The error "client denied by server configuration" generally means that somewhere in your configuration are Allow from and Deny from directives that are preventing access. Read the mod_authz_host documentation for more details.

You should be able to solve this in your VirtualHost by adding something like:

<Location />
  Allow from all
  Order Deny,Allow
</Location>

Or alternatively with a Directory directive:

<Directory "D:/Devel/matysart/matysart_dev1">
  Allow from all
  Order Deny,Allow
</Directory>

Some investigation of your Apache configuration files will probably turn up default restrictions on the default DocumentRoot.

You can easy get that effect without using jQueryUI, for example:

$(document).ready(function(){
    $('#slide').click(function(){
    var hidden = $('.hidden');
    if (hidden.hasClass('visible')){
        hidden.animate({"left":"-1000px"}, "slow").removeClass('visible');
    } else {
        hidden.animate({"left":"0px"}, "slow").addClass('visible');
    }
    });
});

You need to specify which column of the datarow you want to pull data from.

Try the following:

        StringBuilder output = new StringBuilder();
        foreach (DataRow rows in results.Tables[0].Rows)
        {
            foreach (DataColumn col in results.Tables[0].Columns)
            {
                output.AppendFormat("{0} ", rows[col]);
            }

            output.AppendLine();
        }

1. If you want to remove a marker you can do it as marker.remove(); alternatively you can also hide the marker instead of removing it as

 marker.setVisible(false);

and make it visible later whenever needed.
2. However if you want to remove all markers from the map Use map.clear();
Note: map.clear(); will also remove Polylines, Circles etc.
3. If you not want to remove Polylines, Circles etc. than use a loop to the length of marker (if you have multiple markers) to remove those Check out the Example here OR set them Visible false And do not use map.clear(); in such case.

This work for me

The API Doc are very clear on this.

All generators implement the interface org.hibernate.id.IdentifierGenerator. This is a very simple interface. Some applications can choose to provide their own specialized implementations, however, Hibernate provides a range of built-in implementations. The shortcut names for the built-in generators are as follows:

increment

generates identifiers of type long, short or int that are unique only when no other process is inserting data into the same table. Do not use in a cluster.

identity

supports identity columns in DB2, MySQL, MS SQL Server, Sybase and HypersonicSQL. The returned identifier is of type long, short or int.

sequence

uses a sequence in DB2, PostgreSQL, Oracle, SAP DB, McKoi or a generator in Interbase. The returned identifier is of type long, short or int

hilo

uses a hi/lo algorithm to efficiently generate identifiers of type long, short or int, given a table and column (by default hibernate_unique_key and next_hi respectively) as a source of hi values. The hi/lo algorithm generates identifiers that are unique only for a particular database.

seqhilo

uses a hi/lo algorithm to efficiently generate identifiers of type long, short or int, given a named database sequence.

uuid

uses a 128-bit UUID algorithm to generate identifiers of type string that are unique within a network (the IP address is used). The UUID is encoded as a string of 32 hexadecimal digits in length.

guid

uses a database-generated GUID string on MS SQL Server and MySQL.

native

selects identity, sequence or hilo depending upon the capabilities of the underlying database.

assigned

lets the application assign an identifier to the object before save() is called. This is the default strategy if no element is specified.

select

retrieves a primary key, assigned by a database trigger, by selecting the row by some unique key and retrieving the primary key value.

foreign

uses the identifier of another associated object. It is usually used in conjunction with a primary key association.

sequence-identity

a specialized sequence generation strategy that utilizes a database sequence for the actual value generation, but combines this with JDBC3 getGeneratedKeys to return the generated identifier value as part of the insert statement execution. This strategy is only supported on Oracle 10g drivers targeted for JDK 1.4. Comments on these insert statements are disabled due to a bug in the Oracle drivers.

If you are building a simple application with not much concurrent users, you can go for increment, identity, hilo etc.. These are simple to configure and did not need much coding inside the db.

You should choose sequence or guid depending on your database. These are safe and better because the id generation will happen inside the database.

Update: Recently we had an an issue with idendity where primitive type (int) this was fixed by using warapper type (Integer) instead.

Below code worked for me:

<input #fileInput type="file" id="avatar" accept="application/pdf,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document" />

application/pdf means .pdf
application/msword means .doc
application/vnd.openxmlformats-officedocument.wordprocessingml.document means .docx

you have to assign connection to your command object, like..

SqlCommand cmd=new SqlCommand ("insert into time(project,iteration)values('"+this .name1 .SelectedValue +"','"+this .iteration .SelectedValue +"')");
cmd.Connection = conn; 

I found the answer is very very simple...

// It is in java, but it should be same in pyspark
Column col = ds.col("colName"); //the column object
String theNameOftheCol = col.toString();

The variable "theNameOftheCol" is "colName"

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.

If you want to set something on a timer, you can use JavaScript's setTimeout or setInterval methods:

setTimeout ( expression, timeout );
setInterval ( expression, interval );

Where expression is a function and timeout and interval are integers in milliseconds. setTimeout runs the timer once and runs the expression once whereas setInterval will run the expression every time the interval passes.

So in your case it would work something like this:

setInterval(function() {
    //call $.ajax here
}, 5000); //5 seconds

As far as the Ajax goes, see jQuery's ajax() method. If you run an interval, there is nothing stopping you from calling the same ajax() from other places in your code.

If what you want is for an interval to run every 30 seconds until a user initiates a form submission...and then create a new interval after that, that is also possible:

setInterval() returns an integer which is the ID of the interval.

var id = setInterval(function() {
    //call $.ajax here
}, 30000); // 30 seconds

If you store that ID in a variable, you can then call clearInterval(id) which will stop the progression.

Then you can reinstantiate the setInterval() call after you've completed your ajax form submission.

size_t is defined by the C standard to be the unsigned integer return type of the sizeof operator (C99 6.3.5.4.4), and the argument of malloc and friends (C99 7.20.3.3 etc). The actual range is set such that the maximum (SIZE_MAX) is at least 65535 (C99 7.18.3.2).

However, this doesn't let us determine sizeof(size_t). The implementation is free to use any representation it likes for size_t - so there is no upper bound on size - and the implementation is also free to define a byte as 16-bits, in which case size_t can be equivalent to unsigned char.

Putting that aside, however, in general you'll have 32-bit size_t on 32-bit programs, and 64-bit on 64-bit programs, regardless of the data model. Generally the data model only affects static data; for example, in GCC:

`-mcmodel=small'
     Generate code for the small code model: the program and its
     symbols must be linked in the lower 2 GB of the address space.
     Pointers are 64 bits.  Programs can be statically or dynamically
     linked.  This is the default code model.

`-mcmodel=kernel'
     Generate code for the kernel code model.  The kernel runs in the
     negative 2 GB of the address space.  This model has to be used for
     Linux kernel code.

`-mcmodel=medium'
     Generate code for the medium model: The program is linked in the
     lower 2 GB of the address space but symbols can be located
     anywhere in the address space.  Programs can be statically or
     dynamically linked, but building of shared libraries are not
     supported with the medium model.

`-mcmodel=large'
     Generate code for the large model: This model makes no assumptions
     about addresses and sizes of sections.

You'll note that pointers are 64-bit in all cases; and there's little point to having 64-bit pointers but not 64-bit sizes, after all.

Your question was already answered by the other posters, I'd just like to point out that

 delete from table where id <> 2

(or variants thereof, not id = 2 etc) will not delete rows where id is NULL.

If you also want to delete rows with id = NULL:

delete from table where id <> 2 or id is NULL

I think you don't have to use sub query in this scenario.You can directly left outer join the DEPRMNT table .

While using Left Outer Join ,don't use columns in the RHS table of the join in the where condition, you ll get wrong output

The problem you're having is that the event-handlers are being bound before the elements are present in the DOM, if you wrap the jQuery inside of a $(document).ready() then it should work perfectly well:

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").show("slow");
        });

    });

An alternative is to place the <script></script> at the foot of the page, so it's encountered after the DOM has been loaded and ready.

To make the div hide again, once the #music element is clicked, simply use toggle():

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").toggle();
        });
    });

JS Fiddle demo.

And for fading:

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").fadeToggle();
        });
    });

JS Fiddle demo.

You check if it's null in C# like this:

if(MyObject != null) {
  //do something
}

If you want to check against default (tough to understand the question on the info given) check:

if(MyObject != default(MyObject)) {
 //do something
}

Tips and tricks

less

Why are you using editors to just look at a (large) file?

Under *nix or Cygwin, just use less. (There is a famous saying – "less is more, more or less" – because "less" replaced the earlier Unix command "more", with the addition that you could scroll back up.) Searching and navigating under less is very similar to Vim, but there is no swap file and little RAM used.

There is a Win32 port of GNU less. See the "less" section of the answer above.

Perl

Perl is good for quick scripts, and its .. (range flip-flop) operator makes for a nice selection mechanism to limit the crud you have to wade through.

For example:

$ perl -n -e 'print if ( 1000000 .. 2000000)' humongo.txt | less

This will extract everything from line 1 million to line 2 million, and allow you to sift the output manually in less.

Another example:

$ perl -n -e 'print if ( /regex one/ .. /regex two/)' humongo.txt | less

This starts printing when the "regular expression one" finds something, and stops when the "regular expression two" find the end of an interesting block. It may find multiple blocks. Sift the output...

logparser

This is another useful tool you can use. To quote the Wikipedia article:

logparser is a flexible command line utility that was initially written by Gabriele Giuseppini, a Microsoft employee, to automate tests for IIS logging. It was intended for use with the Windows operating system, and was included with the IIS 6.0 Resource Kit Tools. The default behavior of logparser works like a "data processing pipeline", by taking an SQL expression on the command line, and outputting the lines containing matches for the SQL expression.

Microsoft describes Logparser as a powerful, versatile tool that provides universal query access to text-based data such as log files, XML files and CSV files, as well as key data sources on the Windows operating system such as the Event Log, the Registry, the file system, and Active Directory. The results of the input query can be custom-formatted in text based output, or they can be persisted to more specialty targets like SQL, SYSLOG, or a chart.

Example usage:

C:\>logparser.exe -i:textline -o:tsv "select Index, Text from 'c:\path\to\file.log' where line > 1000 and line < 2000"
C:\>logparser.exe -i:textline -o:tsv "select Index, Text from 'c:\path\to\file.log' where line like '%pattern%'"

The relativity of sizes

100 MB isn't too big. 3 GB is getting kind of big. I used to work at a print & mail facility that created about 2% of U.S. first class mail. One of the systems for which I was the tech lead accounted for about 15+% of the pieces of mail. We had some big files to debug here and there.

And more...

Enable Remote Access (Grant) Home / Tutorials / Mysql / Enable Remote Access (Grant) If you try to connect to your mysql server from remote machine, and run into error like below, this article is for you.

ERROR 1130 (HY000): Host ‘1.2.3.4’ is not allowed to connect to this MySQL server

Change mysql config

Start with editing mysql config file

vim /etc/mysql/my.cnf

Comment out following lines.

#bind-address           = 127.0.0.1
#skip-networking

If you do not find skip-networking line, add it and comment out it.

Restart mysql server.

~ /etc/init.d/mysql restart

Change GRANT privilege

You may be surprised to see even after above change you are not getting remote access or getting access but not able to all databases.

By default, mysql username and password you are using is allowed to access mysql-server locally. So need to update privilege.

Run a command like below to access from all machines. (Replace USERNAME and PASSWORD by your credentials.)

mysql> GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'%' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;

Run a command like below to give access from specific IP. (Replace USERNAME and PASSWORD by your credentials.)

mysql> GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'1.2.3.4' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;

You can replace 1.2.3.4 with your IP. You can run above command many times to GRANT access from multiple IPs.

You can also specify a separate USERNAME & PASSWORD for remote access.

You can check final outcome by:

SELECT * from information_schema.user_privileges where grantee like "'USERNAME'%";

Finally, you may also need to run:

mysql> FLUSH PRIVILEGES;

Test Connection

From terminal/command-line:

mysql -h HOST -u USERNAME -pPASSWORD

If you get a mysql shell, don’t forget to run show databases; to check if you have right privileges from remote machines.

Bonus-Tip: Revoke Access

If you accidentally grant access to a user, then better have revoking option handy.

Following will revoke all options for USERNAME from all machines:

mysql> REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'USERNAME'@'%';
Following will revoke all options for USERNAME from particular IP:

mysql> REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'USERNAME'@'1.2.3.4';
Its better to check information_schema.user_privileges table after running REVOKE command.

If you see USAGE privilege after running REVOKE command, its fine. It is as good as no privilege at all. I am not sure if it can be revoked.

If you want something a little more elegant/integrated, you can use a decorator to extend the input directive with support for type=file. The main caveat to keep in mind is that this method will not work in IE9 since IE9 didn't implement the File API. Using JavaScript to upload binary data regardless of type via XHR is simply not possible natively in IE9 or earlier (use of ActiveXObject to access the local filesystem doesn't count as using ActiveX is just asking for security troubles).

This exact method also requires AngularJS 1.4.x or later, but you may be able to adapt this to use $provide.decorator rather than angular.Module.decorator - I wrote this gist to demonstrate how to do it while conforming to John Papa's AngularJS style guide:

(function() {
    'use strict';

    /**
    * @ngdoc input
    * @name input[file]
    *
    * @description
    * Adds very basic support for ngModel to `input[type=file]` fields.
    *
    * Requires AngularJS 1.4.x or later. Does not support Internet Explorer 9 - the browser's
    * implementation of `HTMLInputElement` must have a `files` property for file inputs.
    *
    * @param {string} ngModel
    *  Assignable AngularJS expression to data-bind to. The data-bound object will be an instance
    *  of {@link https://developer.mozilla.org/en-US/docs/Web/API/FileList `FileList`}.
    * @param {string=} name Property name of the form under which the control is published.
    * @param {string=} ngChange
    *  AngularJS expression to be executed when input changes due to user interaction with the
    *  input element.
    */
    angular
        .module('yourModuleNameHere')
        .decorator('inputDirective', myInputFileDecorator);

    myInputFileDecorator.$inject = ['$delegate', '$browser', '$sniffer', '$filter', '$parse'];
    function myInputFileDecorator($delegate, $browser, $sniffer, $filter, $parse) {
        var inputDirective = $delegate[0],
            preLink = inputDirective.link.pre;

        inputDirective.link.pre = function (scope, element, attr, ctrl) {
            if (ctrl[0]) {
                if (angular.lowercase(attr.type) === 'file') {
                    fileInputType(
                        scope, element, attr, ctrl[0], $sniffer, $browser, $filter, $parse);
                } else {
                    preLink.apply(this, arguments);
                }
            }
        };

        return $delegate;
    }

    function fileInputType(scope, element, attr, ctrl, $sniffer, $browser, $filter, $parse) {
        element.on('change', function (ev) {
            if (angular.isDefined(element[0].files)) {
                ctrl.$setViewValue(element[0].files, ev && ev.type);
            }
        })

        ctrl.$isEmpty = function (value) {
            return !value || value.length === 0;
        };
    }
})();

Why wasn't this done in the first place? AngularJS support is intended to reach only as far back as IE9. If you disagree with this decision and think they should have just put this in anyway, then jump the wagon to Angular 2+ because better modern support is literally why Angular 2 exists.

The issue is (as was mentioned before) that without the file api support doing this properly is unfeasible for the core given our baseline being IE9 and polyfilling this stuff is out of the question for core.

Additionally trying to handle this input in a way that is not cross-browser compatible only makes it harder for 3rd party solutions, which now have to fight/disable/workaround the core solution.

...

I'm going to close this just as we closed #1236. Angular 2 is being build to support modern browsers and with that file support will easily available.

your json file look like this

import java.io.*;
import java.util.*;
import org.json.simple.*;
import org.json.simple.parser.*;
public class JSONReadFromTheFileTest {
   public static void main(String[] args) {
      JSONParser parser = new JSONParser();
      try {
         Object obj = parser.parse(new FileReader("/Users/User/Desktop/course.json"));
         JSONObject jsonObject = (JSONObject)obj;
         String name = (String)jsonObject.get("Name");
         String course = (String)jsonObject.get("Course");
         JSONArray subjects = (JSONArray)jsonObject.get("Subjects");
         System.out.println("Name: " + name);
         System.out.println("Course: " + course);
         System.out.println("Subjects:");
         Iterator iterator = subjects.iterator();
         while (iterator.hasNext()) {
            System.out.println(iterator.next());
         }
      } catch(Exception e) {
         e.printStackTrace();
      }
   }
}

the output is

took it from here

I would do the folowing:

Declare separetly the enum, in it´s own file:

public enum RightEnum {
      READ(100), WRITE(200), EDITOR (300);

      private int value;

      private RightEnum (int value) { this.value = value; }


      @Override
      public static Etapa valueOf(Integer value){
           for( RightEnum r : RightEnum .values() ){
              if ( r.getValue().equals(value))
                 return r;
           }
           return null;//or throw exception
     }

      public int getValue() { return value; }


}

Declare a new JPA entity named Right

@Entity
public class Right{
    @Id
    private Integer id;
    //FIElDS

    // constructor
    public Right(RightEnum rightEnum){
          this.id = rightEnum.getValue();
    }

    public Right getInstance(RightEnum rightEnum){
          return new Right(rightEnum);
    }


}

You will also need a converter for receiving this values (JPA 2.1 only and there´s a problem I´ll not discuss here with these enum´s to be directly persisted using the converter, so it will be a one way road only)

import mypackage.RightEnum;
import javax.persistence.AttributeConverter;
import javax.persistence.Converter;

/**
 * 
 * 
 */
@Converter(autoApply = true)
public class RightEnumConverter implements AttributeConverter<RightEnum, Integer>{

    @Override //this method shoudn´t be used, but I implemented anyway, just in case
    public Integer convertToDatabaseColumn(RightEnum attribute) {
        return attribute.getValue();
    }

    @Override
    public RightEnum convertToEntityAttribute(Integer dbData) {
        return RightEnum.valueOf(dbData);
    }

}

The Authority entity:

@Entity
@Table(name = "AUTHORITY_")
public class Authority implements Serializable {


  @Id
  @GeneratedValue(strategy = GenerationType.AUTO)
  @Column(name = "AUTHORITY_ID")
  private Long id;

  // the **Entity** to map : 
  private Right right;

  // the **Enum** to map (not to be persisted or updated) : 
  @Column(name="COLUMN1", insertable = false, updatable = false)
  @Convert(converter = RightEnumConverter.class)
  private RightEnum rightEnum;

}

By doing this way, you can´t set directly to the enum field. However, you can set the Right field in Authority using

autorithy.setRight( Right.getInstance( RightEnum.READ ) );//for example

And if you need to compare, you can use:

authority.getRight().equals( RightEnum.READ ); //for example

Which is pretty cool, I think. It´s not totally correct, since the converter it´s not intended to be use with enum´s. Actually, the documentation says to never use it for this purpose, you should use the @Enumerated annotation instead. The problem is that there are only two enum types: ORDINAL or STRING, but the ORDINAL is tricky and not safe.

However, if it doesn´t satisfy you, you can do something a little more hacky and simpler (or not).

Let´s see.

The RightEnum:

public enum RightEnum {
      READ(100), WRITE(200), EDITOR (300);

      private int value;

      private RightEnum (int value) { 
            try {
                  this.value= value;
                  final Field field = this.getClass().getSuperclass().getDeclaredField("ordinal");
                  field.setAccessible(true);
                  field.set(this, value);
             } catch (Exception e) {//or use more multicatch if you use JDK 1.7+
                  throw new RuntimeException(e);
            }
      }


      @Override
      public static Etapa valueOf(Integer value){
           for( RightEnum r : RightEnum .values() ){
              if ( r.getValue().equals(value))
                 return r;
           }
           return null;//or throw exception
     }

      public int getValue() { return value; }


}

and the Authority entity

@Entity
@Table(name = "AUTHORITY_")
public class Authority implements Serializable {


  @Id
  @GeneratedValue(strategy = GenerationType.AUTO)
  @Column(name = "AUTHORITY_ID")
  private Long id;


  // the **Enum** to map (to be persisted or updated) : 
  @Column(name="COLUMN1")
  @Enumerated(EnumType.ORDINAL)
  private RightEnum rightEnum;

}

In this second idea, its not a perfect situation since we hack the ordinal attribute, but it´s a much smaller coding.

I think that the JPA specification should include the EnumType.ID where the enum value field should be annotated with some kind of @EnumId annotation.

Generally

• Formatting numbers in JavaScript
• Formatting numbers for currency display and more.

In jQuery

• autoNumeric (a decent number formatter & input helper with locale support for jQuery 1.5+)
• jQuery Format (a clientSide implementation of Java's SimpleDateFormat and NumberFormat)
• jquery-numberformatter (number formatter with locale support)

I had also faced same error when i was trying to call bootstrap modal from jquery. But this happens because we are using bootstrap modal and for this we need to attach one cdn bootstrap.min.js which is

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

Hope this will help as I missed that when i was trying to call bootstrap modal from jQuery using

$('#button').on('click',function(){ $('#myModal').modal(); });

myModal is the id of Bootstrap modal and you have to give a click event to a button when you call click that button a pop up modal will be displayed.

It is possible that the executable is statically linked and that is why ldd gzip does not see any links - because it isn't. I don't know much about things that far back so I don't know if there would be incompatibilities if libraries are linked in statically. I might expect there to be.

I know it's the most obvious thing going and I'm sure you've done it, but chmod +x ./gzip, yes? No such file or directory is a classic symptom of that not being done, that's why I mention it.

d = DateTime.now.utc

Oops!

That seems to work in Rails, but not vanilla Ruby (and of course that is what the question is asking)

d = Time.now.utc

Does work however.

Is there any reason you need to use DateTime and not Time? Time should include everything you need:

irb(main):016:0> Time.now
=> Thu Apr 16 12:40:44 +0100 2009

All versions of make require that command lines be indented with a TAB (not space) as the first character in the line. If you showed us the entire rule instead of just the two lines in question we could give a clearer answer, but it should be something like:

myTarget: myDependencies
        @echo hi

where the first character in the second line must be TAB.

If you want to avoid including the full path to awk, you need to update your PATH variable to include the path to the directory where awk is located, then you can just type

awk

to run your programs.

Go to Control Panel->System->Advanced and set your PATH environment variable to include "C:\Program Files (x86)\GnuWin32\bin" at the end (separated by a semi-colon) from previous entry.

If by ID:

$('#datepicker').datepicker({
    format: 'dd/mm/yyyy'

});

If by Class:

$('.datepicker').datepicker({
    format: 'dd/mm/yyyy'

});

The correct solution that i get is

<html>
      <head>
        <script type="text/javascript" language="JavaScript">
                  function clickedButton()
            {

                window.location = 'new url'

            }
             </script>
      </head>

      <form name="login_form" method="post">
            ..................
            <input type="button" value="Login" onClick="clickedButton()"/>
      </form>

When you are using foreach loop within view for binded model ... Your model is supposed to be in listed format.

i.e

@model IEnumerable<ViewModels.MyViewModels>


        @{
            if (Model.Count() > 0)
            {            

                @Html.DisplayFor(modelItem => Model.Theme.FirstOrDefault().name)
                @foreach (var theme in Model.Theme)
                {
                   @Html.DisplayFor(modelItem => theme.name)
                   @foreach(var product in theme.Products)
                   {
                      @Html.DisplayFor(modelItem => product.name)
                      @foreach(var order in product.Orders)
                      {
                          @Html.TextBoxFor(modelItem => order.Quantity)
                         @Html.TextAreaFor(modelItem => order.Note)
                          @Html.EditorFor(modelItem => order.DateRequestedDeliveryFor)
                      }
                  }
                }
            }else{
                   <span>No Theam avaiable</span>

Insert pull-right into the class attribute and let bootstrap arrange the buttons.

For Bootstrap 2.3, see: http://getbootstrap.com/2.3.2/components.html#misc > Helper classes > .pull-right.

For Bootstrap 3, see: https://getbootstrap.com/docs/3.3/css/#helper-classes > Helper classes.

For Bootstrap 4, see: https://getbootstrap.com/docs/4.0/utilities/float/#responsive

The pull-right command was removed and replaced with float-right or in general to float-{sm,md,lg,xl}-{left,right,none}

You can use %%~nf to get the filename only as described in the reference for for:

@echo off
    for /R "C:\Users\Admin\Ordner" %%f in (*.flv) do (
    echo %%~nf
)
pause

The following options are available:

Variable with modifier  Description

%~I                     Expands %I which removes any surrounding 
                        quotation marks ("").
%~fI                    Expands %I to a fully qualified path name.
%~dI                    Expands %I to a drive letter only.
%~pI                    Expands %I to a path only.
%~nI                    Expands %I to a file name only.
%~xI                    Expands %I to a file extension only.
%~sI                    Expands path to contain short names only.
%~aI                    Expands %I to the file attributes of file.
%~tI                    Expands %I to the date and time of file.
%~zI                    Expands %I to the size of file.
%~$PATH:I               Searches the directories listed in the PATH environment 
                        variable and expands %I to the fully qualified name of 
                        the first one found. If the environment variable name is 
                        not defined or the file is not found by the search,
                        this modifier expands to the empty string.    

One word: Don't.

OK obviously that isn't a real answer. But still SOAP should be avoided at all costs. ;-) Is it possible to add a proxy server between the iPhone and the web service? Perhaps something that converts REST into SOAP for you?

You could try CSOAP, a SOAP library that depends on libxml2 (which is included in the iPhone SDK).

I've written my own SOAP framework for OSX. However it is not actively maintained and will require some time to port to the iPhone (you'll need to replace NSXML with TouchXML for a start)

Copying the ".txt" file from one folder to another is very simple and question contains the logic. Only missing part is substituting with right information as below:

import os, shutil, glob

src_fldr = r"Source Folder/Directory path"; ## Edit this

dst_fldr = "Destiantion Folder/Directory path"; ## Edit this

try:
  os.makedirs(dst_fldr); ## it creates the destination folder
except:
  print "Folder already exist or some error";

below lines of code will copy the file with *.txt extension files from src_fldr to dst_fldr

for txt_file in glob.glob(src_fldr+"\\*.txt"):
    shutil.copy2(txt_file, dst_fldr);

In win7, if you want to set the correct timezone as a parameter in JRE, you have to edit the file deployment.properties stored in path c:\users\%username%\appdata\locallow\sun\java\deployment adding the string deployment.javaws.jre.1.args=-Duser.timezone\=my_time_zone

A few years ago it was said that update() and digest() were legacy methods and the new streaming API approach was introduced. Now the docs say that either method can be used. For example:

var crypto    = require('crypto');
var text      = 'I love cupcakes';
var secret    = 'abcdeg'; //make this your secret!!
var algorithm = 'sha1';   //consider using sha256
var hash, hmac;

// Method 1 - Writing to a stream
hmac = crypto.createHmac(algorithm, secret);    
hmac.write(text); // write in to the stream
hmac.end();       // can't read from the stream until you call end()
hash = hmac.read().toString('hex');    // read out hmac digest
console.log("Method 1: ", hash);

// Method 2 - Using update and digest:
hmac = crypto.createHmac(algorithm, secret);
hmac.update(text);
hash = hmac.digest('hex');
console.log("Method 2: ", hash);

Tested on node v6.2.2 and v7.7.2

See https://nodejs.org/api/crypto.html#crypto_class_hmac. Gives more examples for using the streaming approach.

Html:

<input type="file" name="input-file" id="input-file">

jQuery:

var fileToUpload = $('#input-file').prop('files')[0];

We want to get first element only, because prop('files') returns array.

Complete answer is located in the official PostgreSQL documentation.

You can use new PG9.0 anonymous code block feature (http://www.postgresql.org/docs/9.1/static/sql-do.html )

DO $$
DECLARE v_List TEXT;
BEGIN
  v_List := 'foobar' ;
  SELECT *
  FROM   dbo.PubLists
  WHERE  Name = v_List;
  -- ...
END $$;

Also you can get the last insert id:

DO $$
DECLARE lastid bigint;
BEGIN
  INSERT INTO test (name) VALUES ('Test Name') 
  RETURNING id INTO lastid;

  SELECT * FROM test WHERE id = lastid;
END $$;

For me, this issue was slightly different than other answers, as I was only receiving 404s on OPTIONS, yet I already had OPTIONS specifically stated in my Integrated Extensionless URL Handler options. Very confusing.

1. As others have stated, runAllManagedModulesForAllRequests="true" in the modules node is an easy way to blanket-fix most Web API 404 issues - although I prefer @DavidAndroidDev 's answer which is much less intrusive. But there was something additional in my case.
2. Unfortunately, I had this set in IIS under Request Filtering in the site:

By adding the following security node to the web.config was necessary to knock that out - full system.webserver included for context:

  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
      <remove name="WebDAVModule" />
    </modules>
    <handlers>
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <remove name="OPTIONSVerbHandler" />
      <remove name="TRACEVerbHandler" />
      <remove name="WebDAV" />
      <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
    <security>
      <requestFiltering>
        <verbs>
          <remove verb="OPTIONS" />
        </verbs>
      </requestFiltering>
    </security>
  </system.webServer>

Although it's not the perfect answer for this question, it is the first result for "IIS OPTIONS 404" on Google, so I hope this helps someone out; cost me an hour today.

I know it's an old post but it come as first suggestion in google search, short answer no, recommended answer user a custom date piker , the correct answer that i use is using a text box to simulate the date input and do any format you want, here is the code

<html>
<body>
date : 
<span style="position: relative;display: inline-block;border: 1px solid #a9a9a9;height: 24px;width: 500px">
    <input type="date" class="xDateContainer" onchange="setCorrect(this,'xTime');" style="position: absolute; opacity: 0.0;height: 100%;width: 100%;"><input type="text" id="xTime" name="xTime" value="dd / mm / yyyy" style="border: none;height: 90%;" tabindex="-1"><span style="display: inline-block;width: 20px;z-index: 2;float: right;padding-top: 3px;" tabindex="-1">&#9660;</span>
</span>
<script language="javascript">
var matchEnterdDate=0;
//function to set back date opacity for non supported browsers
    window.onload =function(){
        var input = document.createElement('input');
        input.setAttribute('type','date');
        input.setAttribute('value', 'some text'); 
        if(input.value === "some text"){
            allDates = document.getElementsByClassName("xDateContainer");
            matchEnterdDate=1;
            for (var i = 0; i < allDates.length; i++) {
                allDates[i].style.opacity = "1";
            } 
        }
    }
//function to convert enterd date to any format
function setCorrect(xObj,xTraget){
    var date = new Date(xObj.value);
    var month = date.getMonth();
    var day = date.getDate();
    var year = date.getFullYear();
    if(month!='NaN'){
        document.getElementById(xTraget).value=day+" / "+month+" / "+year;
    }else{
        if(matchEnterdDate==1){document.getElementById(xTraget).value=xObj.value;}
    }
}
   </script>
  </body>
</html>

1- please note that this method only work for browser that support date type.

2- the first function in JS code is for browser that don't support date type and set the look to a normal text input.

3- if you will use this code for multiple date inputs in your page please change the ID "xTime" of the text input in both function call and the input itself to something else and of course use the name of the input you want for the form submit.

4-on the second function you can use any format you want instead of day+" / "+month+" / "+year for example year+" / "+month+" / "+day and in the text input use a placeholder or value as yyyy / mm / dd for the user when the page load.

import urllib, urllib2, cookielib

username = 'myuser'
password = 'mypassword'

cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
login_data = urllib.urlencode({'username' : username, 'j_password' : password})
opener.open('http://www.example.com/login.php', login_data)
resp = opener.open('http://www.example.com/hiddenpage.php')
print resp.read()

resp.read() is the straight html of the page you want to open, and you can use opener to view any page using your session cookie.

No, it sets all members/elements that haven't been explicitly set to their default-initialisation value, which is zero for numeric types.

The compiler complains on

var completionHandler: (Float)->Void = {}

because the right-hand side is not a closure of the appropriate signature, i.e. a closure taking a float argument. The following would assign a "do nothing" closure to the completion handler:

var completionHandler: (Float)->Void = {
    (arg: Float) -> Void in
}

and this can be shortened to

var completionHandler: (Float)->Void = { arg in }

due to the automatic type inference.

But what you probably want is that the completion handler is initialized to nil in the same way that an Objective-C instance variable is inititialized to nil. In Swift this can be realized with an optional:

var completionHandler: ((Float)->Void)?

Now the property is automatically initialized to nil ("no value"). In Swift you would use optional binding to check of a the completion handler has a value

if let handler = completionHandler {
    handler(result)
}

or optional chaining:

completionHandler?(result)

If your latest commit is on the master branch, you can simply use

git checkout master

Firefox and other programs allow you to increase and decrease the font size with C-+ and C--. I set up my .emacs so that I have that same ability by adding these lines of code:

(global-set-key [C-kp-add] 'text-scale-increase)

(global-set-key [C-kp-subtract] 'text-scale-decrease)

What you probably need to do is redirect the user after the POST / Form Handler script has been ran.

In PHP this is done like so...

<?php
// ... Handle $_POST data, maybe insert it into a database.
// Ok, $_POST data has been handled, redirect the user
header('Location:success.php');
die();
?>

... this should allow you to refresh the page without getting that "Send Data Again" warning.

You can even redirect to the same page (if that's what you're posting to) as the POST variables will not be sent in the headers (and thus not be there to re-POST on refresh)

Always show errors on a testing server. Never show errors on a production server.

Write a script to determine whether the page is on a local, testing, or live server, and set $state to "local", "testing", or "live". Then:

if( $state == "local" || $state == "testing" )
{
    ini_set( "display_errors", "1" );
    error_reporting( E_ALL & ~E_NOTICE );
}
else
{
    error_reporting( 0 );
}

As of Visual Studio 2012, Microsoft no longer provides the built-in deployment package. If you wish to use this package, you will need to use VS2010.

In 2013 you have several options:

• InstallShield
• WiX
• Roll your own

In my projects I create my own installers from scratch, which, since I do not use Windows Installer, have the advantage of being super fast, even on old machines.

The above solutions fix the project or work around the problem in some way. Sometimes you just don't want to fix the project and just hide the warning instead.

To do that, configure the contents of the warning panel and make sure to toggle-off the "build path"->"JRE System Path Problem" category. The UI for this dialog is a bit complex/weird/usability challenged so you might have to fiddle with a few of the options to make it do what you want.

Try out Vertabelo!

It's an online database modeler that supports reverse enginnering.

Just create free of charge Vertabelo account, import an existing database into Vertabelo and voila - your database is in Vertabelo!

It supports following databases:

• PostgreSQL,
• MySQL,
• Oracle,
• IBM DB2,
• HSQLDB,
• MS SQL Server.

I guess you want to do the "Iterating over Keys and Values"

As the doc here says, just add "|keys" in the variable you want and it will magically happen.

{% for key, user in users %}
    <li>{{ key }}: {{ user.username|e }}</li>
{% endfor %}

It never hurts to search before asking :)

Most databases have a native UUID type these days to make working with them easier. If yours doesn't, they're just 128-bit numbers, so you can use BINARY(16), and if you need the text format frequently, e.g. for troubleshooting, then add a calculated column to generate it automatically from the binary column. There is no good reason to store the (much larger) text form.

Use #define OSsymbol and #ifdef OSsymbol where OSsymbol is a #define'able symbol identifying your target OS.

Typically you would include a central header file defining the selected OS symbol and use OS-specific include and library directories to compile and build.

You did not specify your development environment, but I'm pretty sure your compiler provides global defines for common platforms and OSes.

I found that if the application within the httpd server has a rule like "if the X-Frame-Options header exists and has a value, leave it alone; otherwise add the header X-Frame-Options: SAMEORIGIN" then an httpd.conf mod_headers rule like "Header always unset X-Frame-Options" would not suffice. The SAMEORIGIN value would always reach the client.

To remedy this, I add two, not one, mod_headers rules (in the outermost httpd.conf file):

Header set X-Frame-Options ALLOW-FROM http://to.be.deleted.com early
Header unset X-Frame-Options

The first rule tells any internal request handler that some other agent has taken responsibility for clickjack prevention and it can skip its attempt to save the world. It runs with "early" processing. The second rule strips off the entirely unwanted X-Frame-Options header. It runs with "late" processing.

I also add the appropriate Content-Security-Policy headers so that the world remains protected yet multi-sourced Javascript from trusted sites still gets to run.

You can read that here

If you use

{{<br />}}

it'll be escaped. If you want raw html, you gotta use

{{{<br />}}}

EDIT (Feb 5 2017): As @hitautodestruct points out, in vue 2 you should use v-html instead of triple curly braces.

Internal error is due to a HIDDEN character at end of shebang line !! ie line #!/usr/bin/perl

By adding - or -w at end moves the character away from "perl" allowing the path to the perl processor to be found and script to execute.

HIDDEN character is created by the editor used to create the script

If you want the output to be

array([1.6e-01, 9.9e-01, 3.6e-04])

the problem is not really a missing feature of NumPy, but rather that this sort of rounding is not a standard thing to do. You can make your own rounding function which achieves this like so:

def my_round(value, N):
    exponent = np.ceil(np.log10(value))
    return 10**exponent*np.round(value*10**(-exponent), N)

For a general solution handling 0 and negative values as well, you can do something like this:

def my_round(value, N):
    value = np.asarray(value).copy()
    zero_mask = (value == 0)
    value[zero_mask] = 1.0
    sign_mask = (value < 0)
    value[sign_mask] *= -1
    exponent = np.ceil(np.log10(value))
    result = 10**exponent*np.round(value*10**(-exponent), N)
    result[sign_mask] *= -1
    result[zero_mask] = 0.0

If you are working in a browser that doesn't support tabindex="-1", you may be able to get away with just giving the things that need to be skipped a really high tab index. For example tabindex="500" basically moves the object's tab order to the end of the page.

I did this for a long data entry form with a button thrown in the middle of it. It's not a button people click very often so I didn't want them to accidentally tab to it and press enter. disabled wouldn't work because it's a button.

You probably do not need to be making lists and appending them to make your array. You can likely just do it all at once, which is faster since you can use numpy to do your loops instead of doing them yourself in pure python.

To answer your question, as others have said, you cannot access a nested list with two indices like you did. You can if you convert mean_data to an array before not after you try to slice it:

R = np.array(mean_data)[:,0]

instead of

R = np.array(mean_data[:,0])

But, assuming mean_data has a shape nx3, instead of

R = np.array(mean_data)[:,0]
P = np.array(mean_data)[:,1]
Z = np.array(mean_data)[:,2]

You can simply do

A = np.array(mean_data).mean(axis=0)

which averages over the 0th axis and returns a length-n array

But to my original point, I will make up some data to try to illustrate how you can do this without building any lists one item at a time:

If you don't mind to use swift frameworks then us UINeraida to change navigation background as UIColor or HexColor or UIImage and change navigation back button text programmatically, change complete forground text color.

For UINavigationBar

    neraida.navigation.background.color.hexColor("54ad00", isTranslucent: false, viewController: self)
    
    //Change navigation title, backbutton colour
    
    neraida.navigation.foreground.color.uiColor(UIColor.white, viewController: self)
    
    //Change navigation back button title programmatically
    
    neraida.navigation.foreground.backButtonTitle("Custom Title", ViewController: self)
    
    //Apply Background Image to the UINavigationBar
    
    neraida.navigation.background.image("background", edge: (0,0,0,0), barMetrics: .default, isTranslucent: false, viewController: self)

One very simple way to make a method asynchronous is to use Task.Yield() method. As MSDN states:

You can use await Task.Yield(); in an asynchronous method to force the method to complete asynchronously.

Insert it at beginning of your method and it will then return immediately to the caller and complete the rest of the method on another thread.

private async Task<DateTime> CountToAsync(int num = 1000)
{
    await Task.Yield();
    for (int i = 0; i < num; i++)
    {
        Console.WriteLine("#{0}", i);
    }
    return DateTime.Now;
}

Looking at the implementation differences, I see that:

MDC on encodeURIComponent():

• literal characters (regex representation): [-a-zA-Z0-9._*~'()!]

Java 1.5.0 documentation on URLEncoder:

• literal characters (regex representation): [-a-zA-Z0-9._*]
• the space character " " is converted into a plus sign "+".

So basically, to get the desired result, use URLEncoder.encode(s, "UTF-8") and then do some post-processing:

• replace all occurrences of "+" with "%20"
• replace all occurrences of "%xx" representing any of [~'()!] back to their literal counter-parts

in devices which has Android 4.3 and above you should follow these steps:

How to enable Developer Options:

Launch Settings menu.
Find the open the ‘About Device’ menu.
Scroll down to ‘Build Number’.
Next, tap on the ‘build number’ section seven times.
After the seventh tap you will be told that you are now a developer.
Go back to Settings menu and the Developer Options menu will now be displayed.

In order to enable the USB Debugging you will simply need to open Developer Options, scroll down and tick the box that says ‘USB Debugging’. That’s it.

Go to File> Project Structure (or press Ctrl+Alt+Shift+S), A popup will open now go to SDK Location Tab you will find JDK Location there refer this image to be more clear.

The search or onclick works... but the issue I found was with the older browsers - the search fails. Lots of plugins (jquery ui autocomplete or fancytree filter) have blur and focus handlers. Adding this to an autocomplete input box worked for me(used this.value == "" because it was faster to evaluate). The blur then focus kept the cursor in the box when you hit the little 'x'.

The PropertyChange and input worked for both IE 10 and IE 8 as well as other browsers:

$("#INPUTID").on("propertychange input", function(e) { 
    if (this.value == "") $(this).blur().focus(); 
});

For FancyTree filter extension, you can use a reset button and force it's click event as follows:

var TheFancyTree = $("#FancyTreeID").fancytree("getTree");

$("input[name=FT_FilterINPUT]").on("propertychange input", function (e) {
    var n,
    leavesOnly = false,
    match = $(this).val();
    // check for the escape key or empty filter
    if (e && e.which === $.ui.keyCode.ESCAPE || $.trim(match) === "") {
        $("button#btnResetSearch").click();
        return;
    }

    n = SiteNavTree.filterNodes(function (node) {
        return MatchContainsAll(CleanDiacriticsString(node.title.toLowerCase()), match);
        }, leavesOnly);

    $("button#btnResetSearch").attr("disabled", false);
    $("span#SiteNavMatches").text("(" + n + " matches)");
}).focus();

// handle the reset and check for empty filter field... 
// set the value to trigger the change
$("button#btnResetSearch").click(function (e) {
    if ($("input[name=FT_FilterINPUT]").val() != "")
        $("input[name=FT_FilterINPUT]").val("");
    $("span#SiteNavMatches").text("");
    SiteNavTree.clearFilter();
}).attr("disabled", true);

Should be able to adapt this for most uses.

Let's just say you have 3 buttons:

<input type="button" disabled="disabled" value="hello world">
<input type="button" disabled value="hello world">
<input type="button" value="hello world">

To style the disabled button you can use the following css:

input[type="button"]:disabled{
    color:#000;
}

This will only affect the button which is disabled.

To stop the color changing when hovering you can use this too:

input[type="button"]:disabled:hover{
    color:#000;
}

You can also avoid this by using a css-reset.

In my case i stopped Tomcat server . then immediately the DB went offline .

I resolved my trouble in correcting the "Additional Library Directory", this one was wrong in indicating "$(SolutionDir)\Release", I changed it in "$(SolutionDir)\$(IntDir)"

To correct it, open your project properties -> Configuration Properties -> Linker -> General -> Additional Library Directory

I hope this will help some poeples with the same trouble ;)

declare @data as varchar(50)

In SQLAlchemy v0.8 and newer, use the inspection system.

from sqlalchemy import inspect

def object_as_dict(obj):
    return {c.key: getattr(obj, c.key)
            for c in inspect(obj).mapper.column_attrs}

user = session.query(User).first()

d = object_as_dict(user)

Note that .key is the attribute name, which can be different from the column name, e.g. in the following case:

class_ = Column('class', Text)

This method also works for column_property.

leDbConnection connection = 
new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Inventar.accdb");

@"SELECT tbl_Computer.*,  tbl_Besitzer.*
  FROM tbl_Computer 
  INNER JOIN tbl_Besitzer ON tbl_Computer.FK_Benutzer = tbl_Besitzer.ID 
  WHERE (((tbl_Besitzer.Vorname)='ma'));", 
connection);

Just export the environment variables you want above the check for a non-interactive shell in ~/.bashrc.

If you wish to clear your entire database.

Because of the foreign-key constraints it matters which sequence the tables are truncated. This is a way to bruteforce this sequence.

    public static void ClearDatabase<T>() where T : DbContext, new()
    {
        using (var context = new T())
        {
            var tableNames = context.Database.SqlQuery<string>("SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE = 'BASE TABLE' AND TABLE_NAME NOT LIKE '%Migration%'").ToList();
            foreach (var tableName in tableNames)
            {
                foreach (var t in tableNames)
                {
                    try
                    {

                        if (context.Database.ExecuteSqlCommand(string.Format("TRUNCATE TABLE [{0}]", tableName)) == 1)
                            break;

                    }
                    catch (Exception ex)
                    {

                    }
                }
            }

            context.SaveChanges();
        }
    }

usage:

ClearDatabase<ApplicationDbContext>();

remember to reinstantiate your DbContext after this.

1. Right click on your project and select "Open Module Settings".

2. Click the "+" button in the top left corner of window to add a new module.

3. Select "Import .JAR or .AAR Package" and click the "Next" button.

4. Find the AAR file using the ellipsis button "..." beside the "File name" field.

5. Keep the app's module selected and click on the Dependencies pane to add the new module as a dependency.

6. Use the "+" button of the dependencies screen and select "Module dependency".

7. Select the module and click "OK".

first find your binaries file where it is saved. get the path in terminal mine is

C:\Users\LENOVO\Documents\postgresql-9.5.21-1-windows-x64-binaries (1)\pgsql\bin

then find your local user data path, it is in mostly

C:\usr\local\pgsql\data

now all we have to hit following command in the binary terminal path:

C:\Users\LENOVO\Documents\postgresql-9.5.21-1-windows-x64-binaries (1)\pgsql\bin>pg_ctl -D "C:\usr\local\pgsql\data" start

all done!

autovaccum launcher started! cheers!

There's a tagName property, and a attributes property as well:

var element = document.getElementById("wtv");
var openTag = "<"+element.tagName;
for (var i = 0; i < element.attributes.length; i++) {
    var attrib = element.attributes[i];
    openTag += " "+attrib.name + "=" + attrib.value;
}
openTag += ">";
alert(openTag);

See also How to iterate through all attributes in an HTML element? (I did!)

To get the contents between the open and close tags you could probably use innerHTML if you don't want to iterate over all the child elements...

alert(element.innerHTML);

... and then get the close tag again with tagName.

var closeTag = "</"+element.tagName+">";
alert(closeTag);

Before your write to Excel need to change the format:

xlApp = New Excel.Application
xlWorkSheet = xlWorkBook.Sheets("Sheet1")

Dim cells As Excel.Range = xlWorkSheet.Cells

'set each cell's format to Text
cells.NumberFormat = "@"

'reset horizontal alignment to the right
cells.HorizontalAlignment = Excel.XlHAlign.xlHAlignRight

React Native provides a .measure(...) method which takes a callback and calls it with the offsets and width/height of a component:

myComponent.measure( (fx, fy, width, height, px, py) => {

    console.log('Component width is: ' + width)
    console.log('Component height is: ' + height)
    console.log('X offset to frame: ' + fx)
    console.log('Y offset to frame: ' + fy)
    console.log('X offset to page: ' + px)
    console.log('Y offset to page: ' + py)
})

Example...

The following calculates the layout of a custom component after it is rendered:

class MyComponent extends React.Component {
    render() {
        return <View ref={view => { this.myComponent = view; }} />
    }
    componentDidMount() {
        // Print component dimensions to console
        this.myComponent.measure( (fx, fy, width, height, px, py) => {
            console.log('Component width is: ' + width)
            console.log('Component height is: ' + height)
            console.log('X offset to frame: ' + fx)
            console.log('Y offset to frame: ' + fy)
            console.log('X offset to page: ' + px)
            console.log('Y offset to page: ' + py)
        })        
    }
}

Bug notes

• Note that sometimes the component does not finish rendering before componentDidMount() is called. If you are getting zeros as a result from measure(...), then wrapping it in a setTimeout should solve the problem, i.e.:

  setTimeout( myComponent.measure(...), 0 )
  

if you're connecting to a postgres database, the following works:

result = cursor.execute(query)

if result.returns_rows:
    # we got rows!
    return [{k:v for k,v in zip(result.keys(), r)} for r in result.rows]
else:
    return None

You can do so starting with Postgres 9.1:

with rows as (
INSERT INTO Table1 (name) VALUES ('a_title') RETURNING id
)
INSERT INTO Table2 (val)
SELECT id
FROM rows

In the meanwhile, if you're only interested in the id, you can do so with a trigger:

create function t1_ins_into_t2()
  returns trigger
as $$
begin
  insert into table2 (val) values (new.id);
  return new;
end;
$$ language plpgsql;

create trigger t1_ins_into_t2
  after insert on table1
for each row
execute procedure t1_ins_into_t2();

If you don't want to recompile (as Visual Leak Detector requires) I would recommend WinDbg, which is both powerful and fast (though it's not as easy to use as one could desire).

On the other hand, if you don't want to mess with WinDbg, you can take a look at UMDH, which is also developed by Microsoft and it's easier to learn.

Take a look at these links in order to learn more about WinDbg, memory leaks and memory management in general:

• Memory Leak Detection Using Windbg
• Memory Leak Detection in MFC
• Common WinDbg Commands (Thematically Grouped)
• C/C++ Memory Corruption And Memory Leaks
• The Memory Management Reference
• Using LeakDiag to Debug Unmanaged Memory Leaks
• Heap: Pleasures and Pains

This is what I finally came up with, which works great!

{=SUM(IF((ISTEXT('Worksheet Name!A:A))+(ISTEXT('CCSA Associates'!E:E)),1,0))-1}

Don't forget since it is an array to type the formula above without the "{}", and to CTRL + SHIFT + ENTER instead of just ENTER for the "{}" to appear and for it to be entered properly.

(start -> run -> services.msc) and look for the postgresql-[version] service then right click and enable it

There are all kinds of wonderful ways to specify commits - see the specifying revisions section of man git-rev-parse for more details. In this case, you probably want:

git diff HEAD@{1}

The @{1} means "the previous position of the ref I've specified", so that evaluates to what you had checked out previously - just before the pull. You can tack HEAD on the end there if you also have some changes in your work tree and you don't want to see the diffs for them.

I'm not sure what you're asking for with "the commit ID of my latest version of the file" - the commit "ID" (SHA1 hash) is that 40-character hex right at the top of every entry in the output of git log. It's the hash for the entire commit, not for a given file. You don't really ever need more - if you want to diff just one file across the pull, do

git diff HEAD@{1} filename

This is a general thing - if you want to know about the state of a file in a given commit, you specify the commit and the file, not an ID/hash specific to the file.

CharlesB's answer and helmbert's answer are both helpful, but it took me a while to understand them. Here's another way of putting it:

• A tag is a pointer to a commit, and commits exist independently of branches.
  • It is important to understand that tags have no direct relationship with branches - they only ever identify a commit.
    • That commit can be pointed to from any number of branches - i.e., it can be part of the history of any number of branches - including none.
  • Therefore, running git show <tag> to see a tag's details contains no reference to any branches, only the ID of the commit that the tag points to.
    • (Commit IDs (a.k.a. object names or SHA-1 IDs) are 40-character strings composed of hex. digits that are hashes over the contents of a commit; e.g.: 6f6b5997506d48fc6267b0b60c3f0261b6afe7a2)

• Branches come into play only indirectly:
  • At the time of creating a tag, by implying the commit that the tag will point to:
    • Not specifying a target for a tag defaults to the current branch's most recent commit (a.k.a. HEAD); e.g.:
      • git tag v0.1.0 # tags HEAD of *current* branch
    • Specifying a branch name as the tag target defaults to that branch's most recent commit; e.g.:
      • git tag v0.1.0 develop # tags HEAD of 'develop' branch
    • (As others have noted, you can also specify a commit ID explicitly as the tag's target.)
  • When using git describe to describe the current branch:
    • git describe [--tags] describes the current branch in terms of the commits since the most recent [possibly lightweight] tag in this branch's history.
    • Thus, the tag referenced by git describe may NOT reflect the most recently created tag overall.

Sprint as defined in pure Scrum has the duration 30 calendar days. However Iteration length could be anything as defined by the team.

As a summary, I would describe the wider impact of the repository pattern. It allows all of your code to use objects without having to know how the objects are persisted. All of the knowledge of persistence, including mapping from tables to objects, is safely contained in the repository.

Very often, you will find SQL queries scattered in the codebase and when you come to add a column to a table you have to search code files to try and find usages of a table. The impact of the change is far-reaching.

With the repository pattern, you would only need to change one object and one repository. The impact is very small.

Perhaps it would help to think about why you would use the repository pattern. Here are some reasons:

• You have a single place to make changes to your data access

• You have a single place responsible for a set of tables (usually)

• It is easy to replace a repository with a fake implementation for testing - so you don't need to have a database available to your unit tests

There are other benefits too, for example, if you were using MySQL and wanted to switch to SQL Server - but I have never actually seen this in practice!

I implemented maxlength behaviour on textarea recently, and run into problem described in this question: Chrome counts characters wrong in textarea with maxlength attribute.

So all implementations listed here will work little buggy. To solve this issue I add .replace(/(\r\n|\n|\r)/g, "11") before .length. And kept it in mind when cuting string.

I ended with something like this:

var maxlength = el.attr("maxlength");
var val = el.val();
var length = val.length;
var realLength = val.replace(/(\r\n|\n|\r)/g, "11").length;
if (realLength > maxlength) {
    el.val(val.slice(0, maxlength - (realLength - length)));
}

Don't sure if it solves problem completely, but it works for me for now.

Some more details in relation with the response from Cody Gray. As it took me some time to digest it I though it might be usefull to others.

First, some definitions:

1. There are TypeNames, which are string representations of the type of an object, interface, etc. For example, Bar is a TypeName in Public Class Bar, or in Dim Foo as Bar. TypeNames could be seen as "labels" used in the code to tell the compiler which type definition to look for in a dictionary where all available types would be described.
2. There are System.Type objects which contain a value. This value indicates a type; just like a String would take some text or an Int would take a number, except we are storing types instead of text or numbers. Type objects contain the type definitions, as well as its corresponding TypeName.

Second, the theory:

1. Foo.GetType() returns a Type object which contains the type for the variable Foo. In other words, it tells you what Foo is an instance of.
2. GetType(Bar) returns a Type object which contains the type for the TypeName Bar.

3. In some instances, the type an object has been Cast to is different from the type an object was first instantiated from. In the following example, MyObj is an Integer cast into an Object:

   Dim MyVal As Integer = 42 Dim MyObj As Object = CType(MyVal, Object)

So, is MyObj of type Object or of type Integer? MyObj.GetType() will tell you it is an Integer.

4. But here comes the Type Of Foo Is Bar feature, which allows you to ascertain a variable Foo is compatible with a TypeName Bar. Type Of MyObj Is Integer and Type Of MyObj Is Object will both return True. For most cases, TypeOf will indicate a variable is compatible with a TypeName if the variable is of that Type or a Type that derives from it. More info here: https://docs.microsoft.com/en-us/dotnet/visual-basic/language-reference/operators/typeof-operator#remarks

The test below illustrate quite well the behaviour and usage of each of the mentionned keywords and properties.

Public Sub TestMethod1()

    Dim MyValInt As Integer = 42
    Dim MyValDble As Double = CType(MyValInt, Double)
    Dim MyObj As Object = CType(MyValDble, Object)

    Debug.Print(MyValInt.GetType.ToString) 'Returns System.Int32
    Debug.Print(MyValDble.GetType.ToString) 'Returns System.Double
    Debug.Print(MyObj.GetType.ToString) 'Returns System.Double

    Debug.Print(MyValInt.GetType.GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(MyValDble.GetType.GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(MyObj.GetType.GetType.ToString) 'Returns System.RuntimeType

    Debug.Print(GetType(Integer).GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(GetType(Double).GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(GetType(Object).GetType.ToString) 'Returns System.RuntimeType

    Debug.Print(MyValInt.GetType = GetType(Integer)) '# Returns True
    Debug.Print(MyValInt.GetType = GetType(Double)) 'Returns False
    Debug.Print(MyValInt.GetType = GetType(Object)) 'Returns False

    Debug.Print(MyValDble.GetType = GetType(Integer)) 'Returns False
    Debug.Print(MyValDble.GetType = GetType(Double)) '# Returns True
    Debug.Print(MyValDble.GetType = GetType(Object)) 'Returns False

    Debug.Print(MyObj.GetType = GetType(Integer)) 'Returns False
    Debug.Print(MyObj.GetType = GetType(Double)) '# Returns True
    Debug.Print(MyObj.GetType = GetType(Object)) 'Returns False

    Debug.Print(TypeOf MyObj Is Integer) 'Returns False
    Debug.Print(TypeOf MyObj Is Double) '# Returns True
    Debug.Print(TypeOf MyObj Is Object) '# Returns True


End Sub

EDIT

You can also use Information.TypeName(Object) to get the TypeName of a given object. For example,

Dim Foo as Bar
Dim Result as String
Result = TypeName(Foo)
Debug.Print(Result) 'Will display "Bar"

You could use the Redis Keyspace Notifications by using psubscribe and "__keyevent@<DB-INDEX>__:expired".

With that, each time that a key will expire, you will get a message published on your redis connection.

Regarding your question basically you create a temporary "normal" key using set with an expiration time in s/ms. It should match the name of the key that you wish to delete in your set.

As your temporary key will be published to your redis connection holding the "__keyevent@0__:expired" when it expired, you can easily delete your key from your original set as the message will have the name of the key.

A simple example in practice on that page : https://medium.com/@micah1powell/using-redis-keyspace-notifications-for-a-reminder-service-with-node-c05047befec3

doc : https://redis.io/topics/notifications ( look for the flag xE)

I assume you're talking about a UIButton with UIButtonTypeRoundedRect? You can't change the background color of that. When you try changing it's background color you're rather changing the color of the rect the button is drawn on (which is usually clear). So there are two ways to go. Either you subclass UIButton and overwrite its -drawRect: method or you create images for the different button states (which is perfectly fine to do).

If you set the background images in Interface Builder you should notice that IB doesn't support setting images for all the states the button can have, so I recommend setting the images in code like this:

UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton setBackgroundImage:[UIImage imageNamed:@"normal.png"] forState:UIControlStateNormal];
[myButton setBackgroundImage:[UIImage imageNamed:@"disabled.png"] forState:UIControlStateDisabled];
[myButton setBackgroundImage:[UIImage imageNamed:@"selected.png"] forState:UIControlStateSelected];
[myButton setBackgroundImage:[UIImage imageNamed:@"higligted.png"] forState:UIControlStateHighlighted];
[myButton setBackgroundImage:[UIImage imageNamed:@"highlighted+selected.png"] forState:(UIControlStateHighlighted | UIControlStateSelected)];

The last line shows how to set an image for the selected & highlighted state (that's the one IB can't set). You don't need the selected images (line 4 & 6) if you're button dosn't need a selected state.

echo adds spaces between the arguments passed to it. $text is subject to variable expansion and word splitting, so your echo command is equivalent to:

echo -e "this" "is" "line" "one\n" "this" "is" "line" "two\n"  ...

You can see that a space will be added before "this". You can either remove the newline characters, and quote $text to preserve the newlines:

text="this is line one
this is line two
this is line three"

echo "$text" > filename

Or you could use printf, which is more robust and portable than echo:

printf "%s\n" "this is line one" "this is line two" "this is line three" > filename

In bash, which supports brace expansion, you could even do:

printf "%s\n" "this is line "{one,two,three} > filename

The native system packages installed with python installation in Debian based systems can be found at :

/usr/lib/python2.7/dist-packages/

In OSX - /Library/Python/2.7/site-packages

by using this small code :

from distutils.sysconfig import get_python_lib
print get_python_lib()

However, the list of packages installed via pip can be found at :

/usr/local/bin/

Or one can simply write the following command to list all paths where python packages are.

>>> import site; site.getsitepackages()
['/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages']

Note: the location might vary based on your OS, like in OSX

>>> import site; site.getsitepackages()
['/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/site-python', '/Library/Python/2.7/site-packages']

Best answer of that question I've seen is:

I faced this error several times and, it was due to transferring large resources(larger than 3MB) from server to client.

$("#closeLink").click(closeIt);

Let's say you want to call your function passing some args to it i.e., closeIt(1, false). Then, you should build an anonymous function and call closeIt from it.

$("#closeLink").click(function() {
    closeIt(1, false);
});

robocopy seems to be the most versatile. See it's other options in the help

Try this.

Dim Workbk as workbook
Set Workbk = thisworkbook

Now everything you program will apply just for your containing macro workbook.

Integer i = 5; //example

Long l = Long.valueOf(i.longValue());

This avoids the performance hit of converting to a String. The longValue() method in Integer is just a cast of the int value. The Long.valueOf() method gives the vm a chance to use a cached value.

Suppose you need to pass an arraylist of following class from current activity to next activity // class of the objects those in the arraylist // remember to implement the class from Serializable interface // Serializable means it converts the object into stream of bytes and helps to transfer that object

public class Question implements Serializable {
... 
... 
...
}

in your current activity you probably have an ArrayList as follows

ArrayList<Question> qsList = new ArrayList<>();
qsList.add(new Question(1));
qsList.add(new Question(2));
qsList.add(new Question(3));

// intialize Bundle instance
Bundle b = new Bundle();
// putting questions list into the bundle .. as key value pair.
// so you can retrieve the arrayList with this key
b.putSerializable("questions", (Serializable) qsList);
Intent i = new Intent(CurrentActivity.this, NextActivity.class);
i.putExtras(b);
startActivity(i);

in order to get the arraylist within the next activity

//get the bundle
Bundle b = getIntent().getExtras();
//getting the arraylist from the key
ArrayList<Question> q = (ArrayList<Question>) b.getSerializable("questions");

Atomic size is 4096 bytes, max size is 65536 bytes. Sendfile uses 16 pipes each of 4096 bytes size. cmd : ioctl(fd, FIONREAD, &buff_size).

AForge.net is a free (open-source) library with Fast Fourier Transform support. (See Sources/Imaging/ComplexImage.cs for usage, Sources/Math/FourierTransform.cs for implemenation)

To make it easier add a custom function and call it when ever you want that changing the value also trigger change

$.fn.valAndTrigger = function (element) {
    return $(this).val(element).trigger('change');
}

and

$("#sample").valAndTirgger("NewValue");

Or you can override the val function to always call the change when the val is called

(function ($) {
    var originalVal = $.fn.val;
    $.fn.val = function (value) {
        this.trigger("change");
        return originalVal.call(this, value);
    };
})(jQuery);

@derchambers I found one more solution:

import pandas as pd

# make data
df = pd.DataFrame(index=range(1_000_000))
df['1'] = 'CO'
df['2'] = 'BOB'
df['3'] = '01'
df['4'] = 'BILL'

def eval_join(df, columns):

    sum_elements = [f"df['{col}']" for col in list('1234')]
    to_eval = "+ '_' + ".join(sum_elements)

    return eval(to_eval)


#profile
%timeit df3 = eval_join(df, list('1234')) # 504 ms

If your strings are compile time constants (as in your case) you can use the following trick:

#define USER_JACK strcmp(USER, "jack")
#define USER_QUEEN strcmp(USER, "queen")
#if $USER_JACK == 0
#define USER_VS USER_QUEEN
#elif USER_QUEEN == 0
#define USER_VS USER_JACK
#endif

The compiler can tell the result of the strcmp in advance and will replace the strcmp with its result, thus giving you a #define that can be compared with preprocessor directives. I don't know if there's any variance between compilers/dependance on compiler options, but it worked for me on GCC 4.7.2.

EDIT: upon further investigation, it look like this is a toolchain extension, not GCC extension, so take that into consideration...

Console Application is an application (.exe), not a Library (.dll). To make a library, create a new project, select "Class Library" in type of project, then copy the logic of your first code into this new project.

Or you can edit the Project Properties and select Class Library instead of Console Application in Output type.

As some code can be "console" dependant, I think first solution is better if you check your logic when you copy it.

I wrote a tutorial about this a while ago.

The most important point is the "Site URL":

Site URL: http://localhost/app_name/

Where the folder structure is something like:

app_name
¦   index.php
¦

¦   ¦   index.php
¦   ¦
¦   +---css
¦           main.css
¦           reset.css
¦
+---src
        facebook.php
        fb_ca_chain_bundle.crt

EDIT:
Kavya: how does the FB server recognize my localhost even without an IP or port??

I don't think this has anything to do with Facebook, I guess since the iframe src parameter is loaded from client-side it'll treat your local URL as if you put it directly on your browser.

For example have a file on your online server with content (e.g. online.php):

<iframe src="http://localhost/test.php" width="100%" height="100%">
    <p>Not supported!</p>
</iframe>

And on your localhost root directory, have the file test.php:

<?php echo "Hello from Localhost!"; ?>

Now visit http://your_domain.com/online.php you will see your localhost file's content!

This is why realtime subscriptions and deauthorize callbacks (just to mention) won't work with localhost URLs! because Facebook will ping (send http requests) to these URLs but obviously Facebook server won't translate those URLs to yours!

Android Studio 0.8.10+ has introduced an incredibly useful tool called Memory Monitor.

What it's good for:

• Showing available and used memory in a graph, and garbage collection events over time.
• Quickly testing whether app slowness might be related to excessive garbage collection events.
• Quickly testing whether app crashes may be related to running out of memory.

Figure 1. Forcing a GC (Garbage Collection) event on Android Memory Monitor

You can have plenty good information on your app's RAM real-time consumption by using it.

Sorting a tuple is quite simple:

tuple(sorted(t))

A degree of control is possible over how information travels from a third-party website to Facebook when a page is shared (or liked, etc.). In order to make this possible, information is sent via Open Graph meta tags in the <head> part of the website’s code.

You can use .rstrip('\n') to only remove newlines from the end of the string:

for i in contents:
    alist.append(i.rstrip('\n'))

This leaves all other whitespace intact. If you don't care about whitespace at the start and end of your lines, then the big heavy hammer is called .strip().

However, since you are reading from a file and are pulling everything into memory anyway, better to use the str.splitlines() method; this splits one string on line separators and returns a list of lines without those separators; use this on the file.read() result and don't use file.readlines() at all:

alist = t.read().splitlines()

As you're using Python 3, there is no urllib module anymore. It has been split into several modules.

This would be equivalent to urlretrieve:

import urllib.request
data = urllib.request.urlretrieve("http://...")

urlretrieve behaves exactly the same way as it did in Python 2.x, so it'll work just fine.

Basically:

• urlretrieve saves the file to a temporary file and returns a tuple (filename, headers)
• urlopen returns a Request object whose read method returns a bytestring containing the file contents

In the recent Git, you can add -r/--rebase on pull command to rebase your current branch on top of the upstream branch after fetching. The warning should disappear, but there is a risk that you'll get some conflicts which you'll need to solve.

Alternatively you can checkout different branch with force, then go back to master again, e.g.:

git checkout origin/master -f
git checkout master -f

Then pull it again as usual:

git pull origin master

Using this method can save you time from stashing (git stash) and potential permission issues, reseting files (git reset HEAD --hard), removing files (git clean -fd), etc. Also the above it's easier to remember.

express-fileupload looks like the only middleware that still works these days.

With the same example, multer and connect-multiparty gives an undefined value of req.file or req.files, but express-fileupload works.

And there are a lot of questions and issues raised about the empty value of req.file/req.files.

We had some code here (in VS2005 and C#2.0) where the previous engineers went out of their way to use list.ForEach( delegate(item) { foo;}); instead of foreach(item in list) {foo; }; for all the code that they wrote. e.g. a block of code for reading rows from a dataReader.

I still don't know exactly why they did this.

The drawbacks of list.ForEach() are:

• It is more verbose in C# 2.0. However, in C# 3 onwards, you can use the "=>" syntax to make some nicely terse expressions.

• It is less familiar. People who have to maintain this code will wonder why you did it that way. It took me awhile to decide that there wasn't any reason, except maybe to make the writer seem clever (the quality of the rest of the code undermined that). It was also less readable, with the "})" at the end of the delegate code block.

• See also Bill Wagner's book "Effective C#: 50 Specific Ways to Improve Your C#" where he talks about why foreach is preferred to other loops like for or while loops - the main point is that you are letting the compiler decide the best way to construct the loop. If a future version of the compiler manages to use a faster technique, then you will get this for free by using foreach and rebuilding, rather than changing your code.

• a foreach(item in list) construct allows you to use break or continue if you need to exit the iteration or the loop. But you cannot alter the list inside a foreach loop.

I'm surprised to see that list.ForEach is slightly faster. But that's probably not a valid reason to use it throughout , that would be premature optimisation. If your application uses a database or web service that, not loop control, is almost always going to be be where the time goes. And have you benchmarked it against a for loop too? The list.ForEach could be faster due to using that internally and a for loop without the wrapper would be even faster.

I disagree that the list.ForEach(delegate) version is "more functional" in any significant way. It does pass a function to a function, but there's no big difference in the outcome or program organisation.

I don't think that foreach(item in list) "says exactly how you want it done" - a for(int 1 = 0; i < count; i++) loop does that, a foreach loop leaves the choice of control up to the compiler.

My feeling is, on a new project, to use foreach(item in list) for most loops in order to adhere to the common usage and for readability, and use list.Foreach() only for short blocks, when you can do something more elegantly or compactly with the C# 3 "=>" operator. In cases like that, there may already be a LINQ extension method that is more specific than ForEach(). See if Where(), Select(), Any(), All(), Max() or one of the many other LINQ methods doesn't already do what you want from the loop.

It is indeed possible to change a div elements' width in jQuery:

$("#div").css("width", "300px");

However, what you're describing can be better and more effectively achieved in CSS by setting a width as a percentage:

#div {
    width: 75%;
    /* You can also specify min/max widths */
    min-width: 300px;
    max-width: 960px;
}

This div will then always be 75% the width of the screen, unless the screen width means the div will be smaller than 300px, or bigger than 960px.

I was hit by an unresponsive build and absolutely nothing would allow me to either kill or cancel the build. Even trying to end the task would trigger a user input window, saying that it could not be ended while the build is still going on (quite ironic because that was precisely the intention, to leave that broken state).

The build was taken care of by MSBuild, so the one way I found is to end its task. When forcing MSBuild.exe to end, VS will wake up and finally see the build as cancelled, allowing you to work again.

Hope this helps someone in the same situation.

Using old C++ version, you can use this snippet :

template<typename T>
string toBinary(const T& t)
{
  string s = "";
  int n = sizeof(T)*8;
  for(int i=n-1; i>=0; i--)
  {
    s += (t & (1 << i))?"1":"0";
  }
  return s;
}

int main()
{
  char a, b;

  short c;
  a = -58;
  c = -315;

  b = a >> 3;

  cout << "a = " << a << " => " << toBinary(a) << endl;
  cout << "b = " << b << " => " << toBinary(b) << endl;
  cout << "c = " << c << " => " << toBinary(c) << endl;
}

a = => 11000110
b = => 11111000
c = -315 => 1111111011000101

You can use re.escape():

re.escape(string) Return string with all non-alphanumerics backslashed; this is useful if you want to match an arbitrary literal string that may have regular expression metacharacters in it.

>>> import re
>>> re.escape('^a.*$')
'\\^a\\.\\*\\$'

If you are using a Python version < 3.7, this will escape non-alphanumerics that are not part of regular expression syntax as well.

If you are using a Python version < 3.7 but >= 3.3, this will escape non-alphanumerics that are not part of regular expression syntax, except for specifically underscore (_).

This is possible, but you need to use JSONP, not JSON. Stefan's link pointed you in the right direction. The jQuery AJAX page has more information on JSONP.

Remy Sharp has a detailed example using PHP.

function DoPrevent(e) {
  e.preventDefault();
  e.stopPropagation();
}

// Bind:
$(element).on('click', DoPrevent);

// UnBind:
$(element).off('click', DoPrevent);

I would like to run an automation test in different environments.
So I add this to command maven command:

The package.json file is used by npm to learn about your node.js project.

Use npm init to generate package.json files for you!

It comes bundled with npm. Read its documentation here: https://docs.npmjs.com/cli/init

Also, there's an official tool you can use to generate this file programmatically: https://github.com/npm/init-package-json

• Pointers are not booleans
• Modern C/C++ compilers emit a warning when you write if (foo = bar) by accident.

Therefore I prefer

if (foo == NULL)
{
    // null case
}
else
{
    // non null case
}

or

if (foo != NULL)
{
    // non null case
}
else
{
    // null case
}

However, if I were writing a set of style guidelines I would not be putting things like this in it, I would be putting things like:

Make sure you do a null check on the pointer.

You can modify .htaccess like others said, but the fastest solution is to rename the file extension to .php

Check if db name do not have "_" or "-" that helps in my case

Using the DateTime class available in PHP version 5.2 it would be done like this:

$datetime = new DateTime('17 Oct 2008');
echo $datetime->format('c');

See it in action

As of PHP 5.4 you can do this as a one-liner:

echo (new DateTime('17 Oct 2008'))->format('c');

You can use y.count().

It will return the integer value of the number of times a sub string appears in a string.

For example:

string.count("bah") >> 0
string.count("Hello") >> 1

For portability, try this:

#ifdef _WIN32
#include <conio.h>
#else
#include <stdio.h>
#define clrscr() printf("\e[1;1H\e[2J")
#endif

Then simply call clrscr(). On Windows, it will use conio.h's clrscr(), and on Linux, it will use ANSI escape codes.

If you really want to do it "properly", you can eliminate the middlemen (conio, printf, etc.) and do it with just the low-level system tools (prepare for a massive code-dump):

#ifdef _WIN32
#define WIN32_LEAN_AND_MEAN
#include <windows.h>

void ClearScreen()
{
  HANDLE                     hStdOut;
  CONSOLE_SCREEN_BUFFER_INFO csbi;
  DWORD                      count;
  DWORD                      cellCount;
  COORD                      homeCoords = { 0, 0 };

  hStdOut = GetStdHandle( STD_OUTPUT_HANDLE );
  if (hStdOut == INVALID_HANDLE_VALUE) return;

  /* Get the number of cells in the current buffer */
  if (!GetConsoleScreenBufferInfo( hStdOut, &csbi )) return;
  cellCount = csbi.dwSize.X *csbi.dwSize.Y;

  /* Fill the entire buffer with spaces */
  if (!FillConsoleOutputCharacter(
    hStdOut,
    (TCHAR) ' ',
    cellCount,
    homeCoords,
    &count
    )) return;

  /* Fill the entire buffer with the current colors and attributes */
  if (!FillConsoleOutputAttribute(
    hStdOut,
    csbi.wAttributes,
    cellCount,
    homeCoords,
    &count
    )) return;

  /* Move the cursor home */
  SetConsoleCursorPosition( hStdOut, homeCoords );
}

#else // !_WIN32
#include <unistd.h>
#include <term.h>

void ClearScreen()
{
  if (!cur_term)
  {
     int result;
     setupterm( NULL, STDOUT_FILENO, &result );
     if (result <= 0) return;
  }

   putp( tigetstr( "clear" ) );
}
#endif

You can use split function.

    SELECT 
    (select top 1 item from dbo.Split(FullName,',') where id=1 ) Column1,
    (select top 1 item from dbo.Split(FullName,',') where id=2 ) Column2,
    (select top 1 item from dbo.Split(FullName,',') where id=3 ) Column3,
    (select top 1 item from dbo.Split(FullName,',') where id=4 ) Column4,
    FROM MyTbl

StringUtils.isBlank() returns true for blanks(just whitespaces)and for null String as well. Actually it trims the Char sequences and then performs check.

StringUtils.isEmpty() returns true when there is no charsequence in the String parameter or when String parameter is null. Difference is that isEmpty() returns false if String parameter contains just whiltespaces. It considers whitespaces as a state of being non empty.

this.WindowState = FormWindowState.Maximized;

Very simple:

import json
data = json.loads('{"one" : "1", "two" : "2", "three" : "3"}')
print data['two']

If you do import foo (inside bar.py) and import bar (inside foo.py), it will work fine. By the time anything actually runs, both modules will be fully loaded and will have references to each other.

The problem is when instead you do from foo import abc (inside bar.py) and from bar import xyz (inside foo.py). Because now each module requires the other module to already be imported (so that the name we are importing exists) before it can be imported.

you can pass multiple params in url like

http://localhost:2000/custom?brand=dell&limit=20&price=20000&sort=asc

and in order to get this query fields , you can use map like

    @RequestMapping(method = RequestMethod.GET, value = "/custom")
    public String controllerMethod(@RequestParam Map<String, String> customQuery) {

        System.out.println("customQuery = brand " + customQuery.containsKey("brand"));
        System.out.println("customQuery = limit " + customQuery.containsKey("limit"));
        System.out.println("customQuery = price " + customQuery.containsKey("price"));
        System.out.println("customQuery = other " + customQuery.containsKey("other"));
        System.out.println("customQuery = sort " + customQuery.containsKey("sort"));

        return customQuery.toString();
    }

When using hashcodes with any jce provider you first try to get an instance of the algorithm, then update it with the data you want to be hashed and when you are finished you call digest to get the hash value.

MessageDigest sha = MessageDigest.getInstance("SHA-256");
sha.update(in.getBytes());
byte[] digest = sha.digest();

you can use the digest to get a base64 or hex encoded version according to your needs

You can just create your own .white class and add it to the glyphicon element.

1. First, add a data conversion block into your data flow diagram.

2. Open the data conversion block and tick the column for which the error is showing. Below change its data type to unicode string(DT_WSTR) or whatever datatype is expected and save.

3. Go to the destination block. Go to mapping in it and map the newly created element to its corresponding address and save.

4. Right click your project in the solution explorer.select properties. Select configuration properties and select debugging in it. In this, set the Run64BitRunTime option to false (as excel does not handle the 64 bit application very well).

Select Case parameter 
    ' does something here. 
    ' does something here.

Try using combination of map and lambda functions:

aList = map( lambda x: x, set ([1, 2, 6, 9, 0]) )

It is very convenient approach if you have a set of numbers in string and you want to convert it to list of integers:

aList = map( lambda x: int(x), set (['1', '2', '3', '7', '12']) )

I wrote a simple function:

function push(&$arr,$new) {

}

so that I can "upsert" new element easily:

push($my_array, ['a'=>1,'b'=>2])

At the time this question was asked nobody thought about Bitcoin price. In the case of BTC, it is probably insufficient to use DECIMAL(15,2). If the Bitcoin will rise to $100,000 or more, we will need at least DECIMAL(18,9) to support cryptocurrencies in our apps.

DECIMAL(18,9) takes 12 bytes of space in MySQL (4 bytes per 9 digits).

let me share my experience:

my html page designer use:

<script src="https://code.jquery.com/jquery-3.4.1.slim.min.js" integrity="sha384-J6qa4849blE2+poT4WnyKhv5vZF5SrPo0iEjwBvKU7imGFAV0wwj1yYfoRSJoZ+n" crossorigin="anonymous"></script>

when I create a simple AJAX request, getting an error it says, TypeError: $.ajax(…) is not a function

So, i add:

<script src="https://code.jquery.com/jquery-3.4.1.min.js" integrity="sha256-CSXorXvZcTkaix6Yvo6HppcZGetbYMGWSFlBw8HfCJo=" crossorigin="anonymous"></script>

then, it perfectly works for me at least.

C# 9 records and with expressions can make it a little easier, especially if your type has many properties.

You can use something like:

var books2 = books1.Select(b => b with { }).ToList();

I did this as an example:

record Book
{
    public string Name { get; set; }
}

static void Main()
{
    List<Book> books1 = new List<Book>()
    {
        new Book { Name = "Book1.1" },
        new Book { Name = "Book1.2" },
        new Book { Name = "Book1.3" }
    };

    var books2 = books1.Select(b => b with { }).ToList();

    books2[0].Name = "Changed";
    books2[1].Name = "Changed";

    Console.WriteLine("Book1");
    foreach (var item in books1)
    {
        Console.WriteLine(item);
    }

    Console.WriteLine("Book2");
    foreach (var item in books2)
    {
        Console.WriteLine(item);
    }
}

And the result was:

Book1

Book { Name = Book1.1 }

Book { Name = Book1.2 }

Book { Name = Book1.3 }

Book2

Book { Name = Changed }

Book { Name = Changed }

Book { Name = Book1.3 }

A case when process get SIGABRT from itself: Hrvoje mentioned about a buried pure virtual being called from ctor generating an abort, i recreated an example for this. Here when d is to be constructed, it first calls its base class A ctor, and passes inside pointer to itself. the A ctor calls pure virtual method before table was filled with valid pointer, because d is not constructed yet.

#include<iostream>
using namespace std;
class A {
public:
 A(A *pa){pa->f();}
 virtual void f()=0;
};
class D : public A {
public:
 D():A(this){}
 virtual void f() {cout<<"D::f\n";}
};
int main(){
 D d;
 A *pa = &d;
 pa->f();
 return 0;
}

compile: g++ -o aa aa.cpp

ulimit -c unlimited

run: ./aa

pure virtual method called
terminate called without an active exception
Aborted (core dumped)

now lets quickly see the core file, and validate that SIGABRT was indeed called:

gdb aa core

see regs:

Maybe you want to search for some text in all columns of the Pandas dataframe, and not just in the subset of them. In this case, the following code will help.

df[df.apply(lambda row: row.astype(str).str.contains('String To Find').any(), axis=1)]

Warning. This method is relatively slow, albeit convenient.

I had this exact issue while trying to install mayavi.

So I also had the common error: Microsoft Visual C++ 14.0 is required when pip installing a library.

After looking across many web pages and the solutions to this thread, with none of them working. I figured these steps (most taken from previous solutions) allowed this to work.

1. Go to Build Tools for Visual Studio 2017 and install Build Tools for Visual Studio 2017. Which is under All downloads (scroll down) >> Tools for Visual Studio 2017
   • If you have already installed this skip to 2.

2. Select the C++ Components you require (I didn't know which I required so installed many of them).
   • If you have already installed Build Tools for Visual Studio 2017 then open the application Visual Studio Installer then go to Visual Studio Build Tools 2017 >> Modify >> Individual Components and selected the required components.
   • From other answers important components appear to be: C++/CLI support, VC++ 2017 version <...> latest, Visual C++ 2017 Redistributable Update, Visual C++ tools for CMake, Windows 10 SDK <...> for Desktop C++, Visual C++ Build Tools core features, Visual Studio C++ core features.

3. Install/Modify these components for Visual Studio Build Tools 2017.

4. This is the important step. Open the application Visual Studio Installer then go to Visual Studio Build Tools >> Launch. Which will open a CMD window at the correct location for Microsoft Visual Studio\YYYY\BuildTools.

5. Now enter python -m pip install --upgrade setuptools within this CMD window.

6. Finally, in this same CMD window pip install your python library: pip install -U <library>.

1. Implement a slot in your QMainWindow where you will open your new Window,
2. Place a widget on your QMainWindow,
3. Connect a signal from this widget to a slot from the QMainWindow (for example: if the widget is a QPushButton connect the signal click() to the QMainWindow custom slot you have created).

Code example:

MainWindow.h

// ...
include "newwindow.h"
// ...
public slots:
   void openNewWindow();
// ...
private:
   NewWindow *mMyNewWindow;
// ...
}

MainWindow.cpp

// ...
   MainWindow::MainWindow()
   {
      // ...
      connect(mMyButton, SIGNAL(click()), this, SLOT(openNewWindow()));
      // ...
   }
// ...
void MainWindow::openNewWindow()
{
   mMyNewWindow = new NewWindow(); // Be sure to destroy your window somewhere
   mMyNewWindow->show();
   // ...
}

This is an example on how display a custom new window. There are a lot of ways to do this.

You can export the query results to a text file (or insert statements, or even pdf) by right-clicking on Query Result row (any row) and choose Export

using Sql Developer 3.0

See SQL Developer downloads for latest versions

The -H 'Cache-Control: no-cache' argument is not guaranteed to work because the remote server or any proxy layers in between can ignore it. If it doesn't work, you can do it the old-fashioned way, by adding a unique querystring parameter. Usually, the servers/proxies will think it's a unique URL and not use the cache.

curl "http://www.example.com?foo123"

You have to use a different querystring value every time, though. Otherwise, the server/proxies will match the cache again. To automatically generate a different querystring parameter every time, you can use date +%s, which will return the seconds since epoch.

curl "http://www.example.com?$(date +%s)"

I don't know why but you have to add a setTimeout with at least for me 200ms:

setTimeout( function() {$("#DIV_ID").scrollTop(0)}, 200 );

Tested with Firefox / Chrome / Edge.

You need to create a delegate type. The keyword 'delegate' in the anonymous method creation is a bit misleading. You are not creating an anonymous delegate but an anonymous method. The method you created can be used in a delegate. Like this:

myControl.Invoke(new MethodInvoker(delegate() { (MyMethod(this, new MyEventArgs(someParameter)); }));

Have you tried the Generate Scripts (Right click, tasks, generate scripts) option in SQL Management Studio? Does that produce what you mean by a "SQL File"?

Use sprintf():

int someInt = 368;
char str[12];
sprintf(str, "%d", someInt);

All numbers that are representable by int will fit in a 12-char-array without overflow, unless your compiler is somehow using more than 32-bits for int. When using numbers with greater bitsize, e.g. long with most 64-bit compilers, you need to increase the array size—at least 21 characters for 64-bit types.

Simple answer: give these two tds a style field.

<tr>
<td>One</td>
<td style="padding-right: 10px">Two</td>
<td>Three</td>
<td>Four</td>
</tr>

Tidy one: use class name

<tr>
<td>One</td>
<td class="more-padding-on-right">Two</td>
<td>Three</td>
<td>Four</td>
</tr>

.more-padding-on-right {
  padding-right: 10px;
}

Complex one: using nth-child selector in CSS and specify special padding values for these two, which works in modern browsers.

tr td:nth-child(2) {
  padding-right: 10px;
}?

After reviewing all the other answers, I ended up with this:

function oldSchoolMakeBuild(cb) {
    var makeProcess = exec('make -C ./oldSchoolMakeBuild',
         function (error, stdout, stderr) {
             stderr && console.error(stderr);
             cb(error);
        });
    makeProcess.stdout.on('data', function(data) {
        process.stdout.write('oldSchoolMakeBuild: '+ data);
    });
}

Sometimes data will be multiple lines, so the oldSchoolMakeBuild header will appear once for multiple lines. But this didn't bother me enough to change it.

You can loop through a hash map like this

<%
ArrayList list = new ArrayList();
TreeMap itemList=new TreeMap();
itemList.put("test", "test");
list.add(itemList);
pageContext.setAttribute("itemList", list);                            
%>

  <c:forEach items="${itemList}" var="itemrow">
   <input  type="text"  value="<c:out value='${itemrow.test}'/>"/>
  </c:forEach>

csvreader.next() Return the next row of the reader’s iterable object as a list, parsed according to the current dialect.

Any two GUIDs are very likely unique (not equal).

See this SO entry, and from Wikipedia

While each generated GUID is not guaranteed to be unique, the total number of unique keys (2^128 or 3.4×10^38) is so large that the probability of the same number being generated twice is very small. For example, consider the observable universe, which contains about 5×10^22 stars; every star could then have 6.8×10^15 universally unique GUIDs.

So probably you have to wait for many more billion of years, and hope that you hit one before the universe as we know it comes to an end.

If you don't want duplicates in a list, use a HashSet. That way it will be clear to anyone else reading your code what your intention was and you'll have less code to write since HashSet already handles what you are trying to do.

You can undo your Git commits in two ways: First is you can use git revert, if you want to keep your commit history:

git revert HEAD~3
git revert <hashcode of commit>

Second is you can use git reset, which would delete all your commit history and bring your head to commit where you want it.

git reset <hashcode of commit>
git reset HEAD~3

You can also use the --hard keyword if any of it starts behaving otherwise. But, I would only recommend it until it's extremely necessary.

In windows batch scripts, %~s1 expands path parameters to short names. Create this batch file:

@ECHO OFF
echo %~s1

I called mine shortNamePath.cmd and call it like this:

c:\>shortNamePath "c:\Program Files (x86)\Android\android-sdk"
c:\PROGRA~2\Android\ANDROI~1

Edit: here's a version that uses the current directory if no parameter was supplied:

@ECHO OFF
if '%1'=='' (%0 .) else echo %~s1

Called without parameters:

C:\Program Files (x86)\Android\android-sdk>shortNamePath
C:\PROGRA~2\Android\ANDROI~1

If you want absolute urls, you have the third parameter.

$product_url = $this->generateUrl('product_detail', 
    array(
        'slug' => 'slug'
    ),
    UrlGeneratorInterface::ABSOLUTE_URL
);

Remember to include UrlGeneratorInterface.

This is my pure HTML & Javascript solution:

var setHeight = function (element, height) {
    if (!element) {;
        return false;
    }
    else {
        var elementHeight = parseInt(window.getComputedStyle(element, null).height, 10),
        toggleButton = document.createElement('a'),
        text = document.createTextNode('...Show more'),
        parent = element.parentNode;

        toggleButton.src = '#';
        toggleButton.className = 'show-more';
        toggleButton.style.float = 'right';
        toggleButton.style.paddingRight = '15px';
        toggleButton.appendChild(text);

        parent.insertBefore(toggleButton, element.nextSibling);

        element.setAttribute('data-fullheight', elementHeight);
        element.style.height = height;
        return toggleButton;
    }
}

var toggleHeight = function (element, height) {
    if (!element) {
        return false;
    }
    else {
        var full = element.getAttribute('data-fullheight'),
        currentElementHeight = parseInt(element.style.height, 10);

        element.style.height = full == currentElementHeight ? height : full + 'px';
    }
}

var toggleText = function (element) {
    if (!element) {
        return false;
    }
    else {
        var text = element.firstChild.nodeValue;
        element.firstChild.nodeValue = text == '...Show more' ? '...Show less' : '...Show more';
    }
}


var applyToggle = function(elementHeight){
    'use strict';
    return function(){
        toggleHeight(this.previousElementSibling, elementHeight);
        toggleText(this);
    }
}


var modifyDomElements = function(className, elementHeight){
    var elements = document.getElementsByClassName(className);
    var toggleButtonsArray = [];


    for (var index = 0, arrayLength = elements.length; index < arrayLength; index++) {
        var currentElement = elements[index];
        var toggleButton = setHeight(currentElement, elementHeight);
        toggleButtonsArray.push(toggleButton);
    }

    for (var index=0, arrayLength=toggleButtonsArray.length; index<arrayLength; index++){
        toggleButtonsArray[index].onclick = applyToggle(elementHeight);
    }
}

You can then call modifyDomElements function to apply text shortening on all the elements that have shorten-text class name. For that you would need to specify the class name and the height that you would want your elements to be shortened to:

modifyDomElements('shorten-text','50px'); 

Lastly, in your your html, just set the class name on the element you would want your text to get shorten:

<div class="shorten-text">Your long text goes here...</div>

This is a FAQ:

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

You could try one of these solutions:

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

If by "cursor speed", you mean the repeat rate when holding down a key - then have a look here: http://hints.macworld.com/article.php?story=20090823193018149

To summarize, open up a Terminal window and type the following command:

defaults write NSGlobalDomain KeyRepeat -int 0

More detail from the article:

Everybody knows that you can get a pretty fast keyboard repeat rate by changing a slider on the Keyboard tab of the Keyboard & Mouse System Preferences panel. But you can make it even faster! In Terminal, run this command:

defaults write NSGlobalDomain KeyRepeat -int 0

Then log out and log in again. The fastest setting obtainable via System Preferences is 2 (lower numbers are faster), so you may also want to try a value of 1 if 0 seems too fast. You can always visit the Keyboard & Mouse System Preferences panel to undo your changes.

You may find that a few applications don't handle extremely fast keyboard input very well, but most will do just fine with it.

Since this must have an input element as a parent, you could just use

<input type="text" ng-model="foo" ng-change="myOnChangeFunction()">

Alternatively, you could use the ngModelController and add a function to $formatters, which executes functions on input change. See http://docs.angularjs.org/api/ng.directive:ngModel.NgModelController

.directive("myDirective", function() {
  return {
    restrict: 'A',
    require: 'ngModel',
    link: function(scope, element, attr, ngModel) {
      ngModel.$formatters.push(function(value) {
        // Do stuff here, and return the formatted value.
      });
  };
};

If you want to replace a fragment with another, you should have added them dynamically, first of all. Fragments that are hard coded in XML, cannot be replaced.

// Create new fragment and transaction
Fragment newFragment = new ExampleFragment();
FragmentTransaction transaction = getFragmentManager().beginTransaction();

// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack
transaction.replace(R.id.fragment_container, newFragment);
transaction.addToBackStack(null);

// Commit the transaction
transaction.commit();

Refer this post: Replacing a fragment with another fragment inside activity group

Refer1: Replace a fragment programmatically

Actually, your question is how to write a Higher Order Component (HOC). The main goal of using HOC is preventing copy-pasting. You can write your HOC as a purely functional component or as a class here is an example:

    class Child extends Component {
    render() {
        return (
            <div>
                Child
            </div>
        );
    }
}

If you want to write your parent component as a class-based component:

    class Parent extends Component {
    render() {
        return (
            <div>
                {this.props.children}
            </div>
        );
    }
}

If you want to write your parent as a functional component:

    const Parent=props=>{
    return(
        <div>
            {props.children}
        </div>
    )
}

The answers provided above are absolutely correct and worth to read but I just wanted to give a straight forward answer to the question.

The question asked is just a type conversion question and here its conversion from int data type to float data type and for that you can do it by the function :

float()

And for more details you can visit this page.

A shorter answer from here, adapted to this question:

var arr = $('.requiredText');
arr.each(function(index, item) {
   var is_last_item = (index == (arr.length - 1));
});

Just for completeness.

I think this should work.

TextBox1.Height = 100;

You should NOT use jQuery('selector').attr("tagName").toLowerCase(), because it only works in older versions of Jquery.

You could use $('selector').prop("tagName").toLowerCase() if you're certain that you're using a version of jQuery thats >= version 1.6.

Note :

You may think that EVERYONE is using jQuery 1.10+ or something by now (January 2016), but unfortunately that isn't really the case. For example, many people today are still using Drupal 7, and every official release of Drupal 7 to this day includes jQuery 1.4.4 by default.

So if do not know for certain if your project will be using jQuery 1.6+, consider using one of the options that work for ALL versions of jQuery :

Option 1 :

jQuery('selector')[0].tagName.toLowerCase()

Option 2

jQuery('selector')[0].nodeName.toLowerCase()

This does what you want and overcomes some of the problems in other answers:

import matplotlib.pyplot as plt

labels = ["HHZ 1", "HHN", "HHE"]
colors = ["r","g","b"]

f,axs = plt.subplots(3, sharex=True, sharey=True)

# ---- loop over axes ----
for i,ax in enumerate(axs):
  axs[i].plot([0,1],[1,0],color=colors[i],label=labels[i])
  axs[i].legend(loc="upper right")

plt.show()

... produces ...

It may make things more elegant to wrap it in a property.

string MySessionVar
{
   get{
      return Session["MySessionVar"] ?? String.Empty;
   }
   set{
      Session["MySessionVar"] = value;
   }
}

then you can treat it as a string.

if( String.IsNullOrEmpty( MySessionVar ) )
{
   // do something
}

For case1:

INSERT INTO TAB_STUDENT(name_student, id_teacher_fk)
SELECT 'Joe The Student', id_teacher
  FROM TAB_TEACHER
 WHERE name_teacher = 'Professor Jack'
 LIMIT 1

For case2 you just have to do 2 separate insert statements

My solution:

1. Use Edit > Past Special > Paste XML As Classes to get the class in your code
2. Try something like this: create a list of that class (List<class1>), then use the XmlSerializer to serialize that list to a xml file.
3. Now you just replace the body of that file with your data and try to deserialize it.

Code:

StreamReader sr = new StreamReader(@"C:\Users\duongngh\Desktop\Newfolder\abc.txt");
XmlSerializer xml = new XmlSerializer(typeof(Class1[]));
var a = xml.Deserialize(sr);
sr.Close();

NOTE: you must pay attention to the root name, don't change it. Mine is "ArrayOfClass1"

This should work:

$("label[for='comedyclubs']")

I have been working on Swagger equivalent documentation library called Springfox nowadays and I found that in the Spring 5.0.8 (running at present), interface WebMvcConfigurer has been implemented by class WebMvcConfigurationSupport class which we can directly extend.

import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

public class WebConfig extends WebMvcConfigurationSupport { }

And this is how I have used it for setting my resource handling mechanism as follows -

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("swagger-ui.html")
            .addResourceLocations("classpath:/META-INF/resources/");

    registry.addResourceHandler("/webjars/**")
            .addResourceLocations("classpath:/META-INF/resources/webjars/");
}

For a minimal change:

for(int i=0; i<str.Length; i++ )
   if(str[i] >= 'a' && str[i] <= 'z' || str[i] >= 'A' && str[i] <= 'Z')
      errorCount++;

You could use regular expressions, at least if speed is not an issue and you do not really need the actual exact count.

echo realpath(dirname(__FILE__));

If you place this in an included file, it prints the path to this include. To get the path of the parent script, replace __FILE__ with $_SERVER['PHP_SELF']. But be aware that PHP_SELF is a security risk!
