The best way to accomplish this is by simply adding "href" to the link button like below.

<asp:LinkButton runat="server" id="SomeLinkButton" href="url" CssClass="btn btn-primary btn-sm">Button Text</asp:LinkButton>

Using javascript, or doing this programmatically in the page_load, will work as well but is not the best way to go about doing this.

You will get this result:

<a id="MainContent_ctl00_SomeLinkButton" class="btn btn-primary btn-sm" href="url" href="javascript:__doPostBack(&#39;ctl00$MainContent$ctl00$lSomeLinkButton&#39;,&#39;&#39;)">Button Text</a>

You can also get the same results by using using a regular <a href="" class=""></a>.

I have done it accessing the controls inside the cell control. Find in all control collections.

 ControlCollection cc = (ControlCollection)e.Row.Controls[1].Controls;

 Label lbCod = (Label)cc[1];

I have my menu in the site master page. I used the Page_Load() function to make the "Admin" menu item only visible to users with an Admin role.

using System;
using System.Linq;
using Telerik.Web.UI;
using System.Web.Security;



<telerik:RadMenu ID="menu" runat="server" RenderMode="Auto"  >
    <Items>
       <telerik:RadMenuItem    Text="Admin"  Visible="true" />
    </Items>
 </telerik:RadMenu>

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        RadMenuItem item = this.menu.FindItemByText("Admin");
        if (null != item)
        {
            if (Roles.IsUserInRole("Admin"))
            {
                item.Visible = true;   
            }
            else
            {
                item.Visible = false;
            }
        }
    }
}

While the example works, its not the correct way to handle the streams...

You need to ensure the closing of the files/streams with the using clause.. Also, add try/catch to handle IO errors...

       public void DownloadAll()
    {
        string host = @"sftp.domain.com";
        string username = "myusername";
        string password = "mypassword";

        string remoteDirectory = "/RemotePath/";
        string localDirectory = @"C:\LocalDriveFolder\Downloaded\";

        using (var sftp = new SftpClient(host, username, password))
        {
            sftp.Connect();
            var files = sftp.ListDirectory(remoteDirectory);

            foreach (var file in files)
            {
                string remoteFileName = file.Name;
                if ((!file.Name.StartsWith(".")) && ((file.LastWriteTime.Date == DateTime.Today))

                    using (Stream file1 = File.OpenWrite(localDirectory + remoteFileName))
                    { 
                        sftp.DownloadFile(remoteDirectory + remoteFileName, file1);
                    }
            }

        }
    }

I have a nodeJs project and lost my folders after removing the /[project_name].iml file.

This restored the folders while preserving my other project settings:

• Project Settings > Modules
• + Add Content Root

I use the file *nix command to convert a unknown charset file in a utf-8 file

# -*- encoding: utf-8 -*-

# converting a unknown formatting file in utf-8

import codecs
import commands

file_location = "jumper.sub"
file_encoding = commands.getoutput('file -b --mime-encoding %s' % file_location)

file_stream = codecs.open(file_location, 'r', file_encoding)
file_output = codecs.open(file_location+"b", 'w', 'utf-8')

for l in file_stream:
    file_output.write(l)

file_stream.close()
file_output.close()

You're checking the wrong method. Moq requires that you Setup (and then optionally Verify) the method in the dependency class.

You should be doing something more like this:

class MyClassTest
{
    [TestMethod]
    public void MyMethodTest()
    {
        string action = "test";
        Mock<SomeClass> mockSomeClass = new Mock<SomeClass>();

        mockSomeClass.Setup(mock => mock.DoSomething());

        MyClass myClass = new MyClass(mockSomeClass.Object);
        myClass.MyMethod(action);

        // Explicitly verify each expectation...
        mockSomeClass.Verify(mock => mock.DoSomething(), Times.Once());

        // ...or verify everything.
        // mockSomeClass.VerifyAll();
    }
}

In other words, you are verifying that calling MyClass#MyMethod, your class will definitely call SomeClass#DoSomething once in that process. Note that you don't need the Times argument; I was just demonstrating its value.

OFFSET is what you are looking for.

SELECT * FROM table LIMIT 10 OFFSET 10

FYI, [ChildActionOnly] is not available in ASP.NET MVC Core. see some info here

Filter the data directly from DataTable or Dataset:

"MyTable".DefaultView.RowFilter = "<DataTable Field> LIKE '%" + textBox1.Text + "%'";
   this.dataGridView1.DataSource = "MyTable".DefaultView;

Use this code on event KeyUp of Textbox, replace "MyTable" for you table name or dataset, replace for the field where you want make the search.

Yes. The ++ operator is not available in Python. Guido doesn't like these operators.

Try adding this in your vhost config:

RewriteEngine On
RewriteRule ^(.*)$ https://%{HTTP_HOST}$1 [R=301,L]

int number = 1000000000;
string whatYouWant = number.ToString("#,##0");
//You get: 1,000,000,000

Actually Sun's HotSpot JVM uses "mixed-mode" execution. It interprets the method's bytecode until it determines (usually through a counter of some sort) that a particular block of code (method, loop, try-catch block, etc.) is going to be executed a lot, then it JIT compiles it. The time required to JIT compile a method often takes longer than if the method were to be interpreted if it is a seldom run method. Performance is usually higher for "mixed-mode" because the JVM does not waste time JITing code that is rarely, if ever, run. C# and .NET do not do this. .NET JITs everything which, often times, wastes time.

<table style="min-width:50px; max-width:150px;">
    <tr>
        <td style="min-width:50px">one</td>
        <td style="min-width:100px">two</td>
    </tr>
</table>

This works for me using an email script.

Just use the location.host property

switch (location.host) {
    case "xxx.local":
        settings = ...
        break;
    case "xxx.dev.yyy.com":
        settings = ...
        break;
}

There is a way with struct namespace.

The benefit is all enum variables are under a specific namespace to avoid pollution. The issue is that we could only use var not const

type OrderStatusType string

var OrderStatus = struct {
    APPROVED         OrderStatusType
    APPROVAL_PENDING OrderStatusType
    REJECTED         OrderStatusType
    REVISION_PENDING OrderStatusType
}{
    APPROVED:         "approved",
    APPROVAL_PENDING: "approval pending",
    REJECTED:         "rejected",
    REVISION_PENDING: "revision pending",
}

In "classic" C language (C89/90) when you call an undeclared function, C assumes that it returns an int and also attempts to derive the types of its parameters from the types of the actual arguments (no, it doesn't assume that it has no parameters, as someone suggested before).

In your specific example the compiler would look at do_something(dest, src) call and implicitly derive a declaration for do_something. The latter would look as follows

int do_something(char *, char *)

However, later in the code you explicitly declare do_something as

char *do_something(char *, const char *)

As you can see, these declarations are different from each other. This is what the compiler doesn't like.

It's a really old topic but as it still comes up top in search results:

Nowadays you can add additional class fa-fw to set it fixed width.

Example:

<i class="fa fa-pencil fa-fw" aria-hidden="true"></i>

With Log4j2, this can be achieved using the following utility method added to your code.

private static void setLogLevel() {
  if (Boolean.getBoolean("log4j.debug")) {
    Configurator.setLevel(System.getProperty("log4j.logger"), Level.DEBUG);
  }
}

You need these imports

import org.apache.logging.log4j.Level;
import org.apache.logging.log4j.core.config.Configurator;

Now invoke the setLogLevel method in your main() or whereever appropriate and pass command line params -Dlog4j.logger=com.mypackage.Thingie and -Dlog4j.debug=true.

While rolling stone's answer is good, straightforward and functional, I think there are two things it does not solve.

1. If OP wanted to enforce a phone number cannot belong to both a Dude and a Business
2. The inescapable feeling of sadness as a result of defining the relationship on the PhoneNumber model and not on the Dude/Business models. When extra terrestrials come to Earth, and we want to add an Alien model, we need to modify the PhoneNumber (assuming the ETs have phone numbers) instead of simply adding a "phone_numbers" field to the Alien model.

Introduce the content types framework, which exposes some objects that allow us to create a "generic foreign key" on the PhoneNumber model. Then, we can define the reverse relationship on Dude and Business

from django.contrib.contenttypes.fields import GenericForeignKey, GenericRelation
from django.contrib.contenttypes.models import ContentType
from django.db import models

class PhoneNumber(models.Model):
    number = models.CharField()

    content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE)
    object_id = models.PositiveIntegerField()
    owner = GenericForeignKey()

class Dude(models.Model):
    numbers = GenericRelation(PhoneNumber)

class Business(models.Model):
    numbers = GenericRelation(PhoneNumber)

See the docs for details, and perhaps check out this article for a quick tutorial.

Also, here is an article that argues against the use of Generic FKs.

Use the rename() function.

rename("user/image1.jpg", "user/del/image1.jpg");

Your arguments are in the wrong order. The connection comes first according to the docs

<?php
require("constants.php");

// 1. Create a database connection
$connection = mysqli_connect(DB_SERVER,DB_USER,DB_PASS);

if (!$connection) {
    error_log("Failed to connect to MySQL: " . mysqli_error($connection));
    die('Internal server error');
}

// 2. Select a database to use 
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
    error_log("Database selection failed: " . mysqli_error($connection));
    die('Internal server error');
}

?>

UPDATE: This question was the subject of my blog on May 12th 2011. Thanks for the great question!

Suppose you have an interface as you describe, and a hundred classes that implement it. Then you decide to make one of the parameters of one of the interface's methods optional. Are you suggesting that the right thing to do is for the compiler to force the developer to find every implementation of that interface method, and make the parameter optional as well?

Suppose we did that. Now suppose the developer did not have the source code for the implementation:

// in metadata:
public class B 
{ 
    public void TestMethod(bool b) {}
}

// in source code
interface MyInterface 
{ 
    void TestMethod(bool b = false); 
}
class D : B, MyInterface {}
// Legal because D's base class has a public method 
// that implements the interface method

How is the author of D supposed to make this work? Are they required in your world to call up the author of B on the phone and ask them to please ship them a new version of B that makes the method have an optional parameter?

That's not going to fly. What if two people call up the author of B, and one of them wants the default to be true and one of them wants it to be false? What if the author of B simply refuses to play along?

Perhaps in that case they would be required to say:

class D : B, MyInterface 
{
    public new void TestMethod(bool b = false)
    {
        base.TestMethod(b);
    }
}

The proposed feature seems to add a lot of inconvenience for the programmer with no corresponding increase in representative power. What's the compelling benefit of this feature which justifies the increased cost to the user?

UPDATE: In the comments below, supercat suggests a language feature that would genuinely add power to the language and enable some scenarios similar to the one described in this question. FYI, that feature -- default implementations of methods in interfaces -- will be added to C# 8.

This is very simple to understand :-

id is used when we have to apply CSS property to one attribute only.

class is used when we have to use CSS property in many locations within the same page or different.

General :- for unique structure like staring div and buttons layout we use id .

for same CSS throughout the page or project we use class

id is light and class is little heavy

document.getElementById("address_box").value = 
(title + "\n" + address + "\n" + address2 + "\n" + address3 + "\n" + address4);

I have tried the following option in Helios Version of Eclipse. Simply press CTRL+F you will get the "Find/Replace" Window on your screen

If you run Pytest from a terminal:

Run pytest with the --import-mode=append command-line flag.

Argument description in the official documentation: https://docs.pytest.org/en/stable/pythonpath.html

UPD: Before I also wrote how to do the same if you use PyCharm, but community does not like extendend answers, so I removed additional information that probably was helpful to someone who have a similar issue.

The problem is that PhpMyAdmin control user (usually: pma) password does not match the mysql user: pma (same user) password.

To fix it, 1. Set the password you want for user pma here:

"C:\xampp\phpMyAdmin\config.inc.php"

$cfg['Servers'][$i]['controlpass'] = 'your_new_phpmyadmin_pass';

(should be like on line 32)

Then go to mysql, login as root, go to: (I used phpmyadmin to go here)

Database: mysql »Table: user

Edit the user: pma

Select "Password" from the function list (left column) and set "your_new_phpmyadmin_pass" on the right column and hit go.

Restart mysql server.

Now the message should disappear.

If you don't want it to look horrible I'd suggest defining a list of colours in an array and then using a random number generator to pick one.

If you want a truly random colour you can just generate 3 random numbers from 0 to 255 and then use the Color(int,int,int) constructor to create a new Color instance.

Random randomGenerator = new Random();
int red = randomGenerator.nextInt(256);
int green = randomGenerator.nextInt(256);
int blue = randomGenerator.nextInt(256);

Color randomColour = new Color(red,green,blue);

I used this code to show the dialog at the bottom of the screen:

Dialog dlg = <code to create custom dialog>;

Window window = dlg.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();

wlp.gravity = Gravity.BOTTOM;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(wlp);

This code also prevents android from dimming the background of the dialog, if you need it. You should be able to change the gravity parameter to move the dialog about

private void showPictureialog() {
    final Dialog dialog = new Dialog(this,
            android.R.style.Theme_Translucent_NoTitleBar);

    // Setting dialogview
    Window window = dialog.getWindow();
    window.setGravity(Gravity.CENTER);

    window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    dialog.setTitle(null);
    dialog.setContentView(R.layout.selectpic_dialog);
    dialog.setCancelable(true);

    dialog.show();
}

you can customize you dialog based on gravity and layout parameters change gravity and layout parameter on the basis of your requirenment

In python you must always pass in at least one argument to class methods, the argument is self and it is not meaningless its a reference to the instance itself

Correct me if I am wrong, but getClass() will be useful when you want to make sure your instance is NOT a subclass of the class you are comparing with. If you use instanceof in that situation you can NOT know that because:

class A { }

class B extends A { }

Object oA = new A();
Object oB = new B();

oA instanceof A => true
oA instanceof B => false
oB instanceof A => true // <================ HERE
oB instanceof B => true

oA.getClass().equals(A.class) => true
oA.getClass().equals(B.class) => false
oB.getClass().equals(A.class) => false // <===============HERE
oB.getClass().equals(B.class) => true

Print lines where the third field is either snow or snowman only:

awk '$3~/^snow(man)?$/' file

In JavaScript, most functions are both callable and instantiable: they have both a [[Call]] and [[Construct]] internal methods.

As callable objects, you can use parentheses to call them, optionally passing some arguments. As a result of the call, the function can return a value.

var player = makeGamePlayer("John Smith", 15, 3);

The code above calls function makeGamePlayer and stores the returned value in the variable player. In this case, you may want to define the function like this:

function makeGamePlayer(name, totalScore, gamesPlayed) {
  // Define desired object
  var obj = {
    name:  name,
    totalScore: totalScore,
    gamesPlayed: gamesPlayed
  };
  // Return it
  return obj;
}

Additionally, when you call a function you are also passing an additional argument under the hood, which determines the value of this inside the function. In the case above, since makeGamePlayer is not called as a method, the this value will be the global object in sloppy mode, or undefined in strict mode.

As constructors, you can use the new operator to instantiate them. This operator uses the [[Construct]] internal method (only available in constructors), which does something like this:

1. Creates a new object which inherits from the .prototype of the constructor
2. Calls the constructor passing this object as the this value
3. It returns the value returned by the constructor if it's an object, or the object created at step 1 otherwise.

var player = new GamePlayer("John Smith", 15, 3);

The code above creates an instance of GamePlayer and stores the returned value in the variable player. In this case, you may want to define the function like this:

function GamePlayer(name,totalScore,gamesPlayed) {
  // `this` is the instance which is currently being created
  this.name =  name;
  this.totalScore = totalScore;
  this.gamesPlayed = gamesPlayed;
  // No need to return, but you can use `return this;` if you want
}

By convention, constructor names begin with an uppercase letter.

The advantage of using constructors is that the instances inherit from GamePlayer.prototype. Then, you can define properties there and make them available in all instances

I know it's been eight years but I wanted to share this piece of code found in MRuby that shows how __declspec() can bee used at the same level as the export keyword.

/** Declare a public MRuby API function. */
#if defined(MRB_BUILD_AS_DLL)
#if defined(MRB_CORE) || defined(MRB_LIB)
# define MRB_API __declspec(dllexport)
#else
# define MRB_API __declspec(dllimport)
#endif
#else
# define MRB_API extern
#endif

It is very simple: Use the command:

docker-compose restart worker

You can set the time to wait for stop before killing the container (in seconds)

docker-compose restart -t 30 worker

Note that this will restart the container but without rebuilding it. If you want to apply your changes and then restart, take a look at the other answers.

Here's a toggleClass to toggle/add/remove a class on an element:

// If newState is provided add/remove theClass accordingly, otherwise toggle theClass
function toggleClass(elem, theClass, newState) {
    var matchRegExp = new RegExp('(?:^|\\s)' + theClass + '(?!\\S)', 'g');
    var add=(arguments.length>2 ? newState : (elem.className.match(matchRegExp) == null));

    elem.className=elem.className.replace(matchRegExp, ''); // clear all
    if (add) elem.className += ' ' + theClass;
}

There are some funnies restoring old databases into SQL 2008 via the guy; have you tried doing it via TSQL ?

Use Master
Go
RESTORE DATABASE YourDB
FROM DISK = 'C:\YourBackUpFile.bak'
WITH MOVE 'YourMDFLogicalName' TO 'D:\Data\YourMDFFile.mdf',--check and adjust path
MOVE 'YourLDFLogicalName' TO 'D:\Data\YourLDFFile.ldf' 

Here's an example in C on Linux. That's if, you're on Linux and don't mind doing this small bit in ANSI C.

#include <dirent.h>

DIR *dpdf;
struct dirent *epdf;

dpdf = opendir("./");
if (dpdf != NULL){
   while (epdf = readdir(dpdf)){
      printf("Filename: %s",epdf->d_name);
      // std::cout << epdf->d_name << std::endl;
   }
}
closedir(dpdf);

Try doing this...

document.getElementById("MyElement").className += " MyClass";

Got this here...

This is the best and reliable way to do this. Here is a simple example and after that you can develop your custom logic:

//In .ts
public showUploadButton:boolean = false;

if(some logic)
{
    //your logic
    showUploadButton = true;
}

//In template
<button [class]="showUploadButton ? 'btn btn-default': 'btn btn-info'">Upload</button>

By definition, file: URLs are system-dependent, and they have little use. A URL as in your example works when used locally, i.e. the linking page itself is in the user’s computer. But browsers generally refuse to follow file: links on a page that it has fetched with the HTTP protocol, so that the page's own URL is an http: URL. When you click on such a link, nothing happens. The purpose is presumably security: to prevent a remote page from accessing files in the visitor’s computer. (I think this feature was first implemented in Mozilla, then copied to other browsers.)

So if you work with HTML documents in your computer, the file: URLs should work, though there are system-dependent issues in their syntax (how you write path names and file names in such a URL).

If you really need to work with an HTML document on your computers and another HTML document on a web server, the way to make links work is to use the local file as primary and, if needed, use client-side scripting to fetch the document from the server,

An example:

log4j.rootLogger=ERROR, logfile

log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.logfile.datePattern='-'dd'.log'
log4j.appender.logfile.File=log/radius-prod.log
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%-6r %d{ISO8601} %-5p %40.40c %x - %m\n

log4j.logger.foo.bar.Baz=DEBUG, myappender
log4j.additivity.foo.bar.Baz=false

log4j.appender.myappender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.myappender.datePattern='-'dd'.log'
log4j.appender.myappender.File=log/access-ext-dmz-prod.log
log4j.appender.myappender.layout=org.apache.log4j.PatternLayout
log4j.appender.myappender.layout.ConversionPattern=%-6r %d{ISO8601} %-5p %40.40c %x - %m\n

Seems like you could also do this:

__dirname=fs.realpathSync('.');

of course, dont forget fs=require('fs')

(it's not really global in node scripts exactly, its just defined on the module level)

It's simple:

array = []

will set array to be an empty list. (They're called lists in Python, by the way, not arrays)

If that doesn't work for you, edit your question to include a code sample that demonstrates your problem.

Do not use more than one style attribute. Just seperate styles in the style attribute with ; It is a block of inline CSS, so think of this as you would do CSS in a separate stylesheet.

So in this case its: style="height:100px;width:100px;"

You can use this for any CSS style, so if you wanted to change the colour of the text to white: style="height:100px;width:100px;color:#ffffff" and so on.

However, it is worth using inline CSS sparingly, as it can make code less manageable in future. Using an external stylesheet may be a better option for this. It depends really on your requirements. Inline CSS does make for quicker coding.

I will second madExcept and similar tools, like Eurekalog, but I think you can come a good way with FastMM also. With full debugmode enabled, it should give you some clues of whats wrong.

Anyway, even though Delphi uses FastMM as default, it's worth getting the full FastMM for it's additional control over logging.

The accepted answer uses the Apache Commons package but this is how I did it using Java's native libraries

Java 11 and up

import java.util.Base64;

public class Base64Encoding {

    public static void main(String[] args) {
        Base64.Encoder enc = Base64.getEncoder();
        Base64.Decoder dec = Base64.getDecoder();
        String str = "77+9x6s=";

        // encode data using BASE64
        String encoded = enc.encodeToString(str.getBytes());
        System.out.println("encoded value is \t" + encoded);

        // Decode data
        String decoded = new String(dec.decode(encoded));
        System.out.println("decoded value is \t" + decoded);
        System.out.println("original value is \t" + str);
    }
}

Java 6 - 10

import java.io.UnsupportedEncodingException;    
import javax.xml.bind.DatatypeConverter;

public class EncodeString64 {
    public static void main(String[] args) throws UnsupportedEncodingException {

        String str = "77+9x6s=";
        // encode data using BASE64
        String encoded = DatatypeConverter.printBase64Binary(str.getBytes());
        System.out.println("encoded value is \t" + encoded);

        // Decode data 
        String decoded = new String(DatatypeConverter.parseBase64Binary(encoded));
        System.out.println("decoded value is \t" + decoded);

        System.out.println("original value is \t" + str);
    }
}

The better way would be to try/catch the encoding/decoding steps but hopefully you get the idea.

You can build a Rest API or a restful project using ASP.NET MVC and return data as a JSON. An example controller function would be:

        public JsonpResult GetUsers(string userIds)
        {
           var values = JsonConvert.DeserializeObject<List<int>>(userIds);

            var users = _userRepository.GetAllUsersByIds(userIds);

            var collection = users.Select(user => new { id = user.Id, fullname = user.FirstName +" "+ user.LastName });
            var result = new { users = collection };

            return this.Jsonp(result);
        }
        public IQueryable<User> GetAllUsersByIds(List<int> ids)
        {
            return _db.Users.Where(c=> ids.Contains(c.Id));
        }

Then you just call the GetUsers function via a regular AJAX function supplying the array of Ids(in this case I am using jQuery stringify to send the array as string and dematerialize it back in the controller but you can just send the array of ints and receive it as an array of int's in the controller). I've build an entire Restful API using ASP.NET MVC that returns the data as cross domain json and that can be used from any app. That of course if you can use ASP.NET MVC.

function GetUsers()
    {
           var link = '<%= ResolveUrl("~")%>users?callback=?';
           var userIds = [];
            $('#multiselect :selected').each(function (i, selected) {
                userIds[i] = $(selected).val();
            });

            $.ajax({
                url: link,
                traditional: true,
                data: { 'userIds': JSON.stringify(userIds) },
                dataType: "jsonp",
                jsonpCallback: "refreshUsers"
            });
    }

On the Windows platform the Zeus editor has an option to display white space (i.e. View, White sapce menu).

It also has an option to display the file in hex mode (i.e. Tools, Hex Dump menu).

Though all good answers, unfortunately none of them worked for me. So I had to write something old school. ( I was on a bare minimal Linux OS )

$ date -d @$( echo $(( $(date +%s)-$((60*60*24)) )) )

You can combine this with date's usual formatting. Eg.

$ date -d @$( echo $(( $(date +%s)-$((60*60*24)) )) ) +%Y-%m-%d

Explanation : Take date input in terms of epoc seconds ( the -d option ), from which you would have subtracted one day equivalent seconds. This will give the date precisely one day back.

I use correctly in localhost:

header('0');

Maybe that can help someone, I had the same problem.

I've already created two tables with the serializer class and the views. So when I wanted to updated, I had this error.

I followed this steps:

1. I made .\manage.py makemigrations app
2. I executed .\manage.py migrate
3. I erased both tables of my models.py
4. I erased all reference to my tables from serializer and view class.
5. I executed step 1 and 2.
6. I retrieved my changes just in the models.py
7. I executed again step 5.
8. I restored all my changes.

If you're working with Pycharm, local history is very helpfull.

Character.isDigit(string.charAt(0))

Note that this will allow any Unicode digit, not just 0-9. You might prefer:

char c = string.charAt(0);
isDigit = (c >= '0' && c <= '9');

Or the slower regex solutions:

s.substring(0, 1).matches("\\d")
// or the equivalent
s.substring(0, 1).matches("[0-9]")

However, with any of these methods, you must first be sure that the string isn't empty. If it is, charAt(0) and substring(0, 1) will throw a StringIndexOutOfBoundsException. startsWith does not have this problem.

To make the entire condition one line and avoid length checks, you can alter the regexes to the following:

s.matches("\\d.*")
// or the equivalent
s.matches("[0-9].*")

If the condition does not appear in a tight loop in your program, the small performance hit for using regular expressions is not likely to be noticeable.

You need to make your regex pattern 'non-greedy' by adding a '?' after the '.+'

By default, '*' and '+' are greedy in that they will match as long a string of chars as possible, ignoring any matches that might occur within the string.

Non-greedy makes the pattern only match the shortest possible match.

See Watch Out for The Greediness! for a better explanation.

Or alternately, change your regex to

\(([^\)]+)\)

which will match any grouping of parens that do not, themselves, contain parens.

If display: inline; isn't working, try out display: inline-block;. :)

VonC mentioned in his answer how to remote debug from Eclipse.

I would like to add that the JAVA_OPTS settings are already in run.conf.bat. You just have to uncomment them:

in JBOSS_HOME\bin\run.conf.bat on Windows:

rem # Sample JPDA settings for remote socket debugging
set "JAVA_OPTS=%JAVA_OPTS% -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n"

The Linux version is similar and is located at JBOSS_HOME/bin/run.conf

When you want to check the condition at the beginning of the loop, simply negate the condition on a standard while loop:

while(!cond) { ... }

If you need it at the end, use a do ... while loop and negate the condition:

do { ... } while(!cond);

Look at this online backend.

Parse.com

They offer push notifications, social integration, data storage, and the ability to add rich custom logic to your app’s backend with Cloud Code.

If somehow balancePanel won't work, you could use this:

this.Location = new Point(127, 283);

or

anotherObject.Location = new Point(127, 283);

You can use generator expressions like this:

gen = (x for x in xyz if x not in a)

for x in gen:
    print x

See, here you are overriding one of the method of the base class hence if you like to call base class method from inherited class then you have to use super keyword in the same method of the inherited class.

Take a look at SQL Server - Set based random numbers which has a very detailed explanation.

To summarize, the following code generates a random number between 0 and 13 inclusive with a uniform distribution:

ABS(CHECKSUM(NewId())) % 14

To change your range, just change the number at the end of the expression. Be extra careful if you need a range that includes both positive and negative numbers. If you do it wrong, it's possible to double-count the number 0.

A small warning for the math nuts in the room: there is a very slight bias in this code. CHECKSUM() results in numbers that are uniform across the entire range of the sql Int datatype, or at least as near so as my (the editor) testing can show. However, there will be some bias when CHECKSUM() produces a number at the very top end of that range. Any time you get a number between the maximum possible integer and the last exact multiple of the size of your desired range (14 in this case) before that maximum integer, those results are favored over the remaining portion of your range that cannot be produced from that last multiple of 14.

As an example, imagine the entire range of the Int type is only 19. 19 is the largest possible integer you can hold. When CHECKSUM() results in 14-19, these correspond to results 0-5. Those numbers would be heavily favored over 6-13, because CHECKSUM() is twice as likely to generate them. It's easier to demonstrate this visually. Below is the entire possible set of results for our imaginary integer range:

Checksum Integer: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
Range Result:     0 1 2 3 4 5 6 7 8 9 10 11 12 13  0  1  2  3  4  5

You can see here that there are more chances to produce some numbers than others: bias. Thankfully, the actual range of the Int type is much larger... so much so that in most cases the bias is nearly undetectable. However, it is something to be aware of if you ever find yourself doing this for serious security code.

I received this error code 0x800A03EC when trying to save an Excel file created within my .Net application in VS 2017. I changed the Excel.Application object property Visible=True and let it run until the point of failure. Tried to finish the steps manually in Excel and then discovered I could not save the file because of missing folder permissions. I added the Write permission to the folder, and the error went away.

In my Case Everything was right

1) Web Config was configured properly 2) Route prefix and Route attributes were proper

Still i was getting the error. In my Case "Route" attribute (by pressing F12) was point to System.Web.MVc but not System.Web.Http which caused the issue.

Add !important rule to display: table of your .v-center class.

.v-center {
    display:table !important;
    border:2px solid gray;
    height:300px;
}

Your display property is being overridden by bootstrap to display: block.

Example

If you tried all of the other suggestions, and couldn't get any of them to work (like I couldn't), here's something you can try that may be useful.

HTML

<a class="refresh-this-frame" rel="#iframe-id-0">Refresh</a>
<iframe src="" id="iframe-id-0"></iframe>

JS

$('.refresh-this-frame').click(function() {
    var thisIframe = $(this).attr('rel');
    var currentState = $(thisIframe).attr('src');
    function removeSrc() {
        $(thisIframe).attr('src', '');
    }
    setTimeout (removeSrc, 100);
    function replaceSrc() {
        $(thisIframe).attr('src', currentState);
    }
    setTimeout (replaceSrc, 200);
});

I initially set out to try and save some time with RWD and cross-browser testing. I wanted to create a quick page that housed a bunch of iframes, organized into groups that I would show/hide at will. Logically you'd want to be able to easily and quickly refresh any given frame.

I should note that the project I am working on currently, the one in use in this test-bed, is a one-page site with indexed locations (e.g. index.html#home). That may have had something to do with why I couldn't get any of the other solutions to refresh my particular frame.

Having said that, I know it's not the cleanest thing in the world, but it works for my purposes. Hope this helps someone. Now if only I could figure out how to keep the iframe from scrolling the parent page each time there's animation inside iframe...

EDIT: I realized that this doesn't "refresh" the iframe like I'd hoped it would. It will reload the iframe's initial source though. Still can't figure out why I couldn't get any of the other options to work..

UPDATE: The reason I couldn't get any of the other methods to work is because I was testing them in Chrome, and Chrome won't allow you to access an iframe's content (Explanation: Is it likely that future releases of Chrome support contentWindow/contentDocument when iFrame loads a local html file from local html file?) if it doesn't originate from the same location (so far as I understand it). Upon further testing, I can't access contentWindow in FF either.

AMENDED JS

$('.refresh-this-frame').click(function() {
    var targetID = $(this).attr('rel');
    var targetSrc = $(targetID).attr('src');
    var cleanID = targetID.replace("#","");     
    var chromeTest = ( navigator.userAgent.match(/Chrome/g) ? true : false );
    var FFTest = ( navigator.userAgent.match(/Firefox/g) ? true : false );      
    if (chromeTest == true) {
        function removeSrc() {
            $(targetID).attr('src', '');
        }
        setTimeout (removeSrc, 100);
        function replaceSrc() {
            $(targetID).attr('src', targetSrc);
        }
        setTimeout (replaceSrc, 200);
    }
    if (FFTest == true) {
        function removeSrc() {
            $(targetID).attr('src', '');
        }
        setTimeout (removeSrc, 100);
        function replaceSrc() {
            $(targetID).attr('src', targetSrc);
        }
        setTimeout (replaceSrc, 200);
    }       
    if (chromeTest == false && FFTest == false) {
        var targetLoc = (document.getElementById(cleanID).contentWindow.location).toString();
        function removeSrc() {
            $(targetID).attr('src', '');
        }
        setTimeout (removeSrc, 100);
        function replaceSrc2() {
            $(targetID).attr('src', targetLoc);
        }
        setTimeout (replaceSrc2, 200);
    }
});

To sign an assembly with a strong name using attributes

Open AssemblyInfo.cs (in $(SolutionDir)\Properties)

the AssemblyKeyFileAttribute or the AssemblyKeyNameAttribute, specifying the name of the file or container that contains the key pair to use when signing the assembly with a strong name.

add the following code:

[assembly:AssemblyKeyFileAttribute("keyfile.snk")]

The correct approach in Angularjs is to use ng-value for non-string values of models.

Modify your code like this:

<label data-ng-repeat="choice in question.choices">
  <input type="radio" name="response" data-ng-model="choice.isUserAnswer" data-ng-value="true" />
  {{choice.text}}
</label>

Ref: Straight from the horse's mouth

Yes, you can use numpy for that.

import numpy as np
a = arange(3,dtype=float)

a[0] = np.nan
a[1] = np.inf
a[2] = -np.inf

a # is now [nan,inf,-inf]

np.isnan(a[0]) # True
np.isinf(a[1]) # True
np.isinf(a[2]) # True

These days, you can leverage the .NET library from VBA. The following works for me in Excel 2016. Returns the hash as uppercase hex.

Public Function SHA1(ByVal s As String) As String
    Dim Enc As Object, Prov As Object
    Dim Hash() As Byte, i As Integer

    Set Enc = CreateObject("System.Text.UTF8Encoding")
    Set Prov = CreateObject("System.Security.Cryptography.SHA1CryptoServiceProvider")

    Hash = Prov.ComputeHash_2(Enc.GetBytes_4(s))

    SHA1 = ""
    For i = LBound(Hash) To UBound(Hash)
        SHA1 = SHA1 & Hex(Hash(i) \ 16) & Hex(Hash(i) Mod 16)
    Next
End Function

None of these solutions worked for me. These two similar problems offer temporary solutions that worked, it seems the simulator process isn't being shutdown correctly:

Killing Simulator Processes

From https://stackoverflow.com/a/52533391/11279823

1. Quit the simulator & Xcode.
2. Opened Activity monitor, selected cpu option and search for sim, killing all the process shown as result.
3. Then fired up the terminal and run sudo xcrun simctl erase all. It will delete all content of all simulators. By content if you logged in somewhere password will be gone, all developer apps installed in that simulator will be gone.

Opening Simulator before starting the package

From https://stackoverflow.com/a/55374768/11279823

open -a Simulator; npm start

Hopefully a permanent solution is found.

there's a bootstrap function to change the color of table header called thead-dark for dark background of table header and thead-light for light background of table header. Your code will look like this after using this function.

<table class="table">
    <tr class="thead-danger">
        <!-- here I used dark table headre -->
        <th>
            @Html.DisplayNameFor(model => model.name)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.checkBox1)
        </th>
        <th></th>
    </tr>

Please try

sudo a2enmod rewrite

or use correct apache restart command

sudo /etc/init.d/apache2 restart 

The syntax looks right to me ... try to change it to use INNER JOIN ...

Have a look at this.

This is what I'm doing in TypeScript I have a little utils library where I put things like this

export const arrayToHash = (array: any[], id: string = 'id') => 
         array.reduce((obj, item) =>  (obj[item[id]] = item , obj), {})

usage:

const hash = arrayToHash([{id:1,data:'data'},{id:2,data:'data'}])

or if you have a identifier other than 'id'

const hash = arrayToHash([{key:1,data:'data'},{key:2,data:'data'}], 'key')

if you don't want to use float

<div style="text-align:right; margin:0px auto 0px auto;">
<p> Hello </p>
</div>
  <div style="">
<p> Hello </p>
</div>

You mean like this?

> eq = function(x){x*x}
> plot(eq(1:1000), type='l')

(Or whatever range of values is relevant to your function)

Best Method...

SendingActivity

Intent intent = new Intent(SendingActivity.this, RecievingActivity.class);

1. Make sure you can run powershell scripts (it is disabled by default). Likely you have already done this. http://technet.microsoft.com/en-us/library/ee176949.aspx

   Set-ExecutionPolicy RemoteSigned
   

2. Run this python script on your powershell script helloworld.py:

   # -*- coding: iso-8859-1 -*-
   import subprocess, sys
   
   p = subprocess.Popen(["powershell.exe", 
                 "C:\\Users\\USER\\Desktop\\helloworld.ps1"], 
                 stdout=sys.stdout)
   p.communicate()
   

This code is based on python3.4 (or any 3.x series interpreter), though it should work on python2.x series as well.

C:\Users\MacEwin\Desktop>python helloworld.py
Hello World

The two alternative you gave are semantically identical, but using make([]int, 0) will result in an internal call to runtime.makeslice (Go 1.14).

You also have the option to leave it with a nil value:

var myslice []int

As written in the Golang.org blog:

a nil slice is functionally equivalent to a zero-length slice, even though it points to nothing. It has length zero and can be appended to, with allocation.

A nil slice will however json.Marshal() into "null" whereas an empty slice will marshal into "[]", as pointed out by @farwayer.

None of the above options will cause any allocation, as pointed out by @ArmanOrdookhani.

You just need Visual C++ runtime 2015 installed, if you change your php version to the newest version you will get the error for it. this is why apache has php dependency error.

For reactive form, I managed to make it work by using the following example (47 can be replaced with other value or variable):

<div [formGroup]="form">
  <select formControlName="fieldName">
    <option
        *ngFor="let option of options; index as i"
        [selected]="option === 47"
    >
        {{ option }}
    </option>
  </select>
</div>

The "jQuery method" of determining the document size - query everything, take the highest value, and hope for the best - works in most cases, but not in all of them .

If you really need bullet-proof results for the document size, I'd suggest you use my jQuery.documentSize plugin. Unlike the other methods, it actually tests and evaluates browser behaviour when it is loaded and, based on the result, queries the right property from there on out.

The impact of this one-time test on performance is minimal, and the plugin returns the right results in even the weirdest scenarios - not because I say so, but because a massive, auto-generated test suite actually verifies that it does.

Because the plugin is written in vanilla Javascript, you can use it without jQuery, too.

You can try to use the bringChildToFront, you can check if this documentation is helpful in the Android Developers page.

I suppose C# and Java produce equal byte arrays. If you have non-ASCII characters, it's not enough to add an additional 0. My example contains a few special characters:

var str = "Hell ö € O ";
var bytes = [];
var charCode;

for (var i = 0; i < str.length; ++i)
{
    charCode = str.charCodeAt(i);
    bytes.push((charCode & 0xFF00) >> 8);
    bytes.push(charCode & 0xFF);
}

alert(bytes.join(' '));
// 0 72 0 101 0 108 0 108 0 32 0 246 0 32 32 172 0 32 3 169 0 32 216 52 221 30

I don't know if C# places BOM (Byte Order Marks), but if using UTF-16, Java String.getBytes adds following bytes: 254 255.

String s = "Hell ö € O ";
// now add a character outside the BMP (Basic Multilingual Plane)
// we take the violin-symbol (U+1D11E) MUSICAL SYMBOL G CLEF
s += new String(Character.toChars(0x1D11E));
// surrogate codepoints are: d834, dd1e, so one could also write "\ud834\udd1e"

byte[] bytes = s.getBytes("UTF-16");
for (byte aByte : bytes) {
    System.out.print((0xFF & aByte) + " ");
}
// 254 255 0 72 0 101 0 108 0 108 0 32 0 246 0 32 32 172 0 32 3 169 0 32 216 52 221 30

Edit:

Added a special character (U+1D11E) MUSICAL SYMBOL G CLEF (outside BPM, so taking not only 2 bytes in UTF-16, but 4.

Current JavaScript versions use "UCS-2" internally, so this symbol takes the space of 2 normal characters.

I'm not sure but when using charCodeAt it seems we get exactly the surrogate codepoints also used in UTF-16, so non-BPM characters are handled correctly.

This problem is absolutely non-trivial. It might depend on the used JavaScript versions and engines. So if you want reliable solutions, you should have a look at:

• https://github.com/koichik/node-codepoint/
• http://mathiasbynens.be/notes/javascript-escapes
• Mozilla Developer Network: charCodeAt
• BigEndian vs. LittleEndian

You can use pigz instead of gzip, which does gzip compression on multiple cores. Instead of using the -z option, you would pipe it through pigz:

tar cf - paths-to-archive | pigz > archive.tar.gz

By default, pigz uses the number of available cores, or eight if it could not query that. You can ask for more with -p n, e.g. -p 32. pigz has the same options as gzip, so you can request better compression with -9. E.g.

tar cf - paths-to-archive | pigz -9 -p 32 > archive.tar.gz

D or dd deletes and copies the line to the register. You can use Vx which only deletes the line and stays in the normal mode.

I would use Winamp to do this. Create a playlist of files you want to merge into one, select Disk Writer output plugin, choose filename and you're done. The file you will get will be correct MP3 file and you can set bitrate etc.

You can use HTML5 <figcaption>:

<figure>
  <img src="img.jpg" alt="my img"/>
  <figcaption> Your text </figcaption>
</figure>

Working example.

What about this:

while ($row = mysql_fetch_array($result)) 
{
    $new_array[$row['id']]['id'] = $row['id'];
    $new_array[$row['id']]['link'] = $row['link'];
}

To retrieve link and id:

foreach($new_array as $array)
{       
   echo $array['id'].'<br />';
   echo $array['link'].'<br />';
}

The conventional way of handling this doesn't play well with ES6. You can do this instead:

$('.delete').on('click', event => {
  const clickedElement = $(event.target);

  this.delete(clickedElement.data('id'));
});

Note that the event target will be the clicked element, which may not be the element you want (it could be a child that received the event). To get the actual element:

$('.delete').on('click', event => {
  const clickedElement = $(event.target);
  const targetElement = clickedElement.closest('.delete');

  this.delete(targetElement.data('id'));
});

You should probably do some validations before you actually execute your function :

function trim(str) {
    if(typeof str !== 'string') {
        throw new Error('only string parameter supported!');
    }

    return str.replace(/^\s+|\s+$/g,'');
}

Add a third group by adding parens around .*, then replace the subsequence with "number" + m.group(2) + "1". e.g.:

String output = m.replaceFirst("number" + m.group(2) + "1");

I like AstroGrep. The results are shown in a list. A click on a row shows you the whole line as a preview highlighting the hit. It seems to be quite fast, lean and it is free. Tested on Windows 7, 8, 10 and Windows Server 2008 R2. Allows regular expressions.

AstroGrep is a Microsoft Windows GUI File Searching (grep) utility. Its features include regular expressions, versatile printing options, stores most recent used paths and has a "context" feature which is very nice for looking at source code

Reference: AstroGrep

Double the backslashes in the path, like this:

driver.findElement(browsebutton).sendKeys("C:\\Users\\Desktop\\Training\\Training.jpg");

json_decode($jsondata, true);

true turns all properties to array (sequential or not)

I had the same problem. I had to follow these steps to resolve the issue:

1. Make sure you have the following dependencies:

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-core</artifactId>
        <version>${jackson-version}</version> // 2.4.3
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>${jackson-version}</version> // 2.4.3
    </dependency>

2. Create the following filter:

    public class CORSFilter extends OncePerRequestFilter {

        @Override
        protected void doFilterInternal(HttpServletRequest request,
                                        HttpServletResponse response, FilterChain filterChain)
                throws ServletException, IOException {

            String origin = request.getHeader("origin");
            origin = (origin == null || origin.equals("")) ? "null" : origin;
            response.addHeader("Access-Control-Allow-Origin", origin);
            response.addHeader("Access-Control-Allow-Methods", "POST, GET, PUT, UPDATE, DELETE, OPTIONS");
            response.addHeader("Access-Control-Allow-Credentials", "true");
            response.addHeader("Access-Control-Allow-Headers",
                    "Authorization, origin, content-type, accept, x-requested-with");

            filterChain.doFilter(request, response);
        }
    }

3. Apply the above filter for the requests in web.xml

    <filter>
        <filter-name>corsFilter</filter-name>
        <filter-class>com.your.package.CORSFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>corsFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

I hope this is useful to somebody.

Check the MySQL Datetime Functions:

Try this:

SELECT * 
FROM tableA 
WHERE YEAR(columnName) = YEAR(CURRENT_DATE()) AND 
      MONTH(columnName) = MONTH(CURRENT_DATE());

try this

UITextField *field = [[UITextField alloc] initWithFrame:CGRectMake(20, 80, 280, 120)];

Jin Yong - IE has an issue with polluting the global scope with object references to any DOM elements with a "name" or "id" attribute set on the "initial" page load.

Thus you may have issues due to your variable name.

Try this and see if it works.

var someOtherName="abc";
//  ^^^^^^^^^^^^^
document.getElementById('msg').value = someOtherName;
document.getElementById('sp_100').checked = true;

There is a chance (in your original code) that IE attempts to set the value of the input to a reference to that actual element (ignores the error) but leaves you with no new value.

Keep in mind that in IE6/IE7 case doesn't matter for naming objects. IE believes that "foo" "Foo" and "FOO" are all the same object.

Another reason this could be happening is if you are using an iframe that has the sandbox attribute and allow-same-origin isn't set e.g.:

// page.html
<iframe id="f" src="http://localhost:8000/iframe.html" sandbox="allow-scripts"></iframe>
<script type="text/javascript">
    var f = document.getElementById("f").contentWindow;
    // will throw exception
    f.postMessage("hello world!", 'http://localhost:8000');
</script>

// iframe.html
<script type="text/javascript">
    window.addEventListener("message", function(event) {
        console.log(event);
    }, false);
</script>

I haven't found a solution other than:

• add allow-same-origin to the sandbox (didn't want to do that)
• use f.postMessage("hello world!", '*');

You need to put the data before render

Should be like this:

var data = [
  {author: "Pete Hunt", text: "This is one comment"},
  {author: "Jordan Walke", text: "This is *another* comment"}
];

React.render(
  <CommentBox data={data}/>,
  document.getElementById('content')
);

Instead of this:

React.render(
  <CommentBox data={data}/>,
  document.getElementById('content')
);

var data = [
  {author: "Pete Hunt", text: "This is one comment"},
  {author: "Jordan Walke", text: "This is *another* comment"}
];

try launching it via android-studio/eclipse plugin. Thats how I had similar issue when launching it from ubuntu.

Try that out bud

sudo wget http://cdn.mysql.com//Downloads/Connector-Python/mysql-connector-python-2.1.3.tar.gz

gunzip mysql-connector-python-2.1.3.tar.gz

tar xf mysql-connector-python-2.1.3.tar

cd mysql-connector-python-2.1.3

sudo python3 setup.py install

Try the following

Dictionary<int, DateTime> existingItems = 
    (from ObjType ot in TableObj).ToDictionary(x => x.Key);

Or the fully fledged type inferenced version

var existingItems = TableObj.ToDictionary(x => x.Key);

You can do something like this

import React from 'react';

class Header extends React.Component {

constructor() {
    super();
}

checkClick(e, notyId) {
    alert(notyId);
}

render() {
    return (
        <PopupOver func ={this.checkClick } />
    )
}
};

class PopupOver extends React.Component {

constructor(props) {
    super(props);
    this.props.func(this, 1234);
}

render() {
    return (
        <div className="displayinline col-md-12 ">
            Hello
        </div>
    );
}
}

export default Header;

Using statics

var MyComponent = React.createClass({
 statics: {
 customMethod: function(foo) {
  return foo === 'bar';
  }
 },
   render: function() {
 }
});

MyComponent.customMethod('bar');  // true

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"

We have just been going through this same issue, but the other way around. That is, we store dollar amounts as DECIMAL, but now we're finding that, for example, MySQL was calculating a value of 4.389999999993, but when storing this into the DECIMAL field, it was storing it as 4.38 instead of 4.39 like we wanted it to. So, though DOUBLE may cause rounding issues, it seems that DECIMAL can cause some truncating issues as well.

For your example, you'd add this:

interface JQuery{
    printArea():void;
}

Edit: oops, basarat is correct below. I'm not sure why I thought it was compiling but I've updated this answer.

This issue (https://bugs.eclipse.org/394042) is fixed in m2e 1.5.0 which is available for Eclipse Kepler and Luna from this p2 repo :

http://download.eclipse.org/technology/m2e/releases/1.5

If you also use m2e-wtp, you'll need to install m2e-wtp 1.1.0 as well :

In Ruby, the Hash#select is a right option. If you work with Rails, you can use Hash#slice and Hash#slice!. e.g. (rails 3.2.13)

h1 = {:a => 1, :b => 2, :c => 3, :d => 4}

h1.slice(:a, :b)         # return {:a=>1, :b=>2}, but h1 is not changed

h2 = h1.slice!(:a, :b)   # h1 = {:a=>1, :b=>2}, h2 = {:c => 3, :d => 4}

There is now a much easier way to setup Git password caching by double clicking a small exe on Windows. The program is still based on git-credential-winstore mentioned by the top voted answer, although the project has been moved from GitHub to http://gitcredentialstore.codeplex.com/

You can download the exe (and a binary for Mac) from this blog post: https://github.com/blog/1104-credential-caching-for-wrist-friendly-git-usage

Java <= 6.x just allows you to catch one exception for each catch block:

try {

} catch (ExceptionType name) {

} catch (ExceptionType name) {

}

Documentation:

Each catch block is an exception handler and handles the type of exception indicated by its argument. The argument type, ExceptionType, declares the type of exception that the handler can handle and must be the name of a class that inherits from the Throwable class.

For Java 7 you can have multiple Exception caught on one catch block:

catch (IOException|SQLException ex) {
    logger.log(ex);
    throw ex;
}

Documentation:

In Java SE 7 and later, a single catch block can handle more than one type of exception. This feature can reduce code duplication and lessen the temptation to catch an overly broad exception.

Reference: http://docs.oracle.com/javase/tutorial/essential/exceptions/catch.html

Depending on your privileges, this query might work:

SELECT sqltext.TEXT,
req.session_id,
req.status,
req.command,
req.cpu_time,
req.total_elapsed_time
FROM sys.dm_exec_requests req
CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS sqltext

Ref: http://blog.sqlauthority.com/2009/01/07/sql-server-find-currently-running-query-t-sql

For many years I have always used this format:

<?php
    $data = "Hello";

    function sayHello(){
        echo $GLOBALS["data"];
    }

    sayHello();
?>

I find it straightforward and easy to follow. The $GLOBALS is how PHP lets you reference a global variable. If you have used things like $_SERVER, $_POST, etc. then you have reference a global variable without knowing it.

For that particular case you can use:

.detail_container > ul + h1{ 
    color: blue; 
}

But if you need that same selector on many cases, you should have a class for those, like BoltClock said.

Just throw some light in to some issues related to this control.

Date picker is not a standard control that comes with office package. So developers encountered issues like missing date picker controls when application deployed in some other machiens/versions of office. In order to use it you have to activate the reference to the .dll, .ocx file that contains it.

In the event of a missing date picker, you have to replace MSCOMCT2.OCX file in System or System32 directory and register it properly. Try this link to do the proper replacement of the file.

In the VBA editor menu bar-> select tools-> references and then find the date picker reference and check it.

If you need the file, download MSCOMCT2.OCX from here.

I'm not familiar with the Python API but you can always use

SELECT * FROM sqlite_master;

You can use vue-loader and code your components in their own files (Single file components). This will allow you to include scripts and css on a component basis.

Alternative to the nice head / tail way:

ls -al | awk 'NR==2'

or

ls -al | sed -n '2p'

To get the path, you can use:

console.log('document.location', document.location.href);_x000D_
console.log('location.pathname',  window.location.pathname); // Returns path only_x000D_
console.log('location.href', window.location.href); // Returns full URL

In Python 2.x:

• range creates a list, so if you do range(1, 10000000) it creates a list in memory with 9999999 elements.

• xrange is a sequence object that evaluates lazily.

In Python 3:

• range does the equivalent of Python 2's xrange. To get the list, you have to explicitly use list(range(...)).
• xrange no longer exists.

you can find how to do it here. In short it is:

public object this[int i]
{
    get { return InnerList[i]; }
    set { InnerList[i] = value; }
}

If you only need a getter the syntax in answer below can be used as well (starting from C# 6).

This was probably a casting issue. Casting syntax happens when you try to combine two different types of variables. Since we cannot convert a string to an integer or float always, we have to convert our integers into a string. This is how you do it.: str(x). To convert to a integer, it's: int(x), and a float is float(x). Our code will be:

print('Total score for ' + str(name) + ' is ' + str(score))

Also! Run this snippet to see a table of how to convert different types of variables!

<table style="border-collapse: collapse; width: 100%;background-color:maroon; color: #00b2b2;">

Go to Settings->Basic, on top you will find a Switch button which will say App is in development mode.

Click on in development switch button, it will ask you to make app live, and after providing all necessary things, it will become live.

I just had the same problem and ended up doing:

git rebase -i HEAD~N

(N is the number of commits git will show you)

That prompts your text editor and then you can remove the commit you want by deleting the line associated with it.

Kyle's solution worked perfectly fine for me so I made my research in order to avoid any Js and CSS, but just sticking with HTML. Adding a value of selected to the item we want to appear as a header forces it to show in the first place as a placeholder. Something like:

<option selected disabled>Choose here</option>

The complete markup should be along these lines:

<select>
    <option selected disabled>Choose here</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
    <option value="4">Four</option>
    <option value="5">Five</option>
</select>

You can take a look at this fiddle, and here's the result:

If you do not want the sort of placeholder text to appear listed in the options once a user clicks on the select box just add the hidden attribute like so:

<select>
    <option selected disabled hidden>Choose here</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
    <option value="4">Four</option>
    <option value="5">Five</option>
</select>

Check the fiddle here and the screenshot below.

Here is the solution:

<select>
    <option style="display:none;" selected>Select language</option>
    <option>Option 1</option>
    <option>Option 2</option>
</select>

*(myString.end() - 1) maybe? That's not exactly elegant either.

A python-esque myString.at(-1) would be asking too much of an already-bloated class.

In Windows, if you have mapped network drives and you don't know the UNC path for them, you can start a command prompt (Start ? Run ? cmd.exe) and use the net use command to list your mapped drives and their UNC paths:

C:\>net use
New connections will be remembered.

Status       Local     Remote                    Network

-------------------------------------------------------------------------------
OK           Q:        \\server1\foo             Microsoft Windows Network
OK           X:        \\server2\bar             Microsoft Windows Network
The command completed successfully.

Note that this shows the list of mapped and connected network file shares for the user context the command is run under. If you run cmd.exe under your own user account, the results shown are the network file shares for yourself. If you run cmd.exe under another user account, such as the local Administrator, you will instead see the network file shares for that user.

Use:

SELECT *
  FROM YOUR_TABLE
 WHERE creation_date <= TRUNC(SYSDATE) - 30

SYSDATE returns the date & time; TRUNC resets the date to being as of midnight so you can omit it if you want the creation_date that is 30 days previous including the current time.

Depending on your needs, you could also look at using ADD_MONTHS:

SELECT *
  FROM YOUR_TABLE
 WHERE creation_date <= ADD_MONTHS(TRUNC(SYSDATE), -1)

If calculating with dates summertime will cause often 1 uur more or one hour less than midnight (CEST). This causes 1 day difference when dates return. So the dates have to round to the nearest midnight. So the code will be (ths to jamisOn):

    var d = new Date();
    if(d.getHours() < 12) {
    d.setHours(0,0,0,0); // previous midnight day
    } else {
    d.setHours(24,0,0,0); // next midnight day
    }

If only names of regular files immediately contained within a directory (assume it's ~/dirs) are needed, you can do

find ~/docs -type f -maxdepth 1 > filenames.txt

If the library is included in the VS project, you can check .cproj file, e.g.:

Suppose there are 2 tables TableA and TableB with only 2 columns (Id, Data) and following data:

TableA:

|  1 | DataA11 |
|  1 | DataA12 |

Inner Join on column Id will return columns from both the tables and only the matching records:

From Google OAuth2.0 for Client documentation,

• expires_in -- The number of seconds left before the token becomes invalid.

I had this issue and some of the answer work just fine for JS but not for TS here is the reason.

//JS
let couldBeNullOrUndefined;
if(couldBeNullOrUndefined == null) {
  console.log('null OR undefined', couldBeNullOrUndefined);
} else {
  console.log('Has some value', couldBeNullOrUndefined);
}

That is all good as JS has no Types

//TS
let couldBeNullOrUndefined?: string | null; // THIS NEEDS TO BE TYPED AS undefined || null || Type(string)

if(couldBeNullOrUndefined === null) { // TS should always use strict-check
  console.log('null OR undefined', couldBeNullOrUndefined);
} else {
  console.log('Has some value', couldBeNullOrUndefined);
}

In TS if the variable wasn't defined with null when you try to check for that null the tslint | compiler will complain.

//tslint.json
...
"triple-equals":[true],
...

 let couldBeNullOrUndefined?: string; // to fix it add | null

 Types of property 'couldBeNullOrUndefined' are incompatible.
      Type 'string | null' is not assignable to type 'string | undefined'.
        Type 'null' is not assignable to type 'string | undefined'.

suptitle seems the way to go, but for what it's worth, the figure has a transFigure property that you can use:

fig=figure(1)
text(0.5, 0.95, 'test', transform=fig.transFigure, horizontalalignment='center')

You can use Date.before() or Date.after() or Date.equals() for date comparison.

        compareDates("2017-01-13 00:00:00", "2017-01-13 00:00:00");//output will be Date1 is equal Date2 because both date and time are equal

Make sure you have enabled TextQualified option and set it to be ".

In general, questions regarding "magic" variables in Perl can be answered by looking in the Perl predefined variables documentation a la:

perldoc perlvar

However, when you search this documentation for $1, etc., you'll find references in a number of places except the section on these "digit" variables. You have to search for

$<digits>

I would have added this to Brian's answer either by commenting or editing, but I don't have enough rep. If someone adds this I'll remove this answer.

My preferred method is to use PadRight. Instead of clearing the line first, this clears the remainder of the line after the new text is displayed, saving a step:

Console.CursorTop = 0;
Console.CursorLeft = 0;
Console.Write("Whatever...".PadRight(Console.BufferWidth));

This error happens because of your Jre version of Eclipse and Tomcat are mismatched ..either change eclipse one to tomcat one or ViceVersa..

I've created a little directive that bind with the tabindex attribute. It adds/removes the has-focus class dynamically.

@Directive({
    selector: "[tabindex]"
})
export class TabindexDirective {
    constructor(private elementHost: ElementRef) {}

    @HostListener("focus")
    setInputFocus(): void {
        this.elementHost.nativeElement.classList.add("has-focus");
    }

    @HostListener("blur")
    setInputFocusOut(): void {
        this.elementHost.nativeElement.classList.remove("has-focus");
    }
}

The only way to fix this issue for my bootstrap modal (containing a form) was to add the following code to my CSS:

.modal {
    -webkit-overflow-scrolling: auto!important;
}

This will be useful

$("input[type=checkbox]").change((e)=>{ 
  console.log(e.target.checked);
});

A less known difference is that in operating systems with optimistic memory allocation, like Linux, the pointer returned by malloc isn't backed by real memory until the program actually touches it.

calloc does indeed touch the memory (it writes zeroes on it) and thus you'll be sure the OS is backing the allocation with actual RAM (or swap). This is also why it is slower than malloc (not only does it have to zero it, the OS must also find a suitable memory area by possibly swapping out other processes)

See for instance this SO question for further discussion about the behavior of malloc

You have to create an item of type ListBoxItem and add that to the Items collection:

list.Items.add( new ListBoxItem("clan", "sifOsoba"));

String[] result = "hi i'm paul".split("\\s+"); to split across one or more cases.

Or you could take a look at Apache Common StringUtils. It has StringUtils.split(String str) method that splits string using white space as delimiter. It also has other useful utility methods

Error and Exception both extend Throwable, but mostly Error is thrown by JVM in a scenario which is fatal and there is no way for the application program to recover from that error. For instance OutOfMemoryError.

Though even application can raise an Error but its just not a good a practice, instead applications should use checked exceptions for recoverable conditions and runtime exceptions for programming errors.

Turn on visible whitespace in whatever editor you are using and turn on replace tabs with spaces.

While you can use tabs with Python mixing tabs and space usually leads to the error you are experiencing. Replacing tabs with 4 spaces is the recommended approach for writing Python code.

Here are some methods that may help others, though they aren't really services as much as they may be described as "methods that may, after some torture of effort or logic, lead to a claim of on-demand access to Mac OS X" (no doubt I should patent that phrase).

Fundamentally, I am inclined to believe that on-demand (per-hour) hosting does not exist, and @Erik has given information for the shortest feasible services, i.e. monthly hosting.

It seems that one may use EC2 itself, but install OS X on the instance through a lot of elbow grease.

• This article on Lifehacker.com gives instructions for setting up OSX under Virtual Box and depends on hardware virtualization. It seems that the Cluster Compute instances (and Cluster GPU, but ignore these) are the only ones supporting hardware virtualization.
• This article gives instructions for transferring a VirtualBox image to EC2.

Where this gets tricky is I'm not sure if this will work for a cluster compute instance. In fact, I think this is likely to be a royal pain. A similar approach may work for Rackspace or other cloud services.

I found only this site claiming on-demand Mac hosting, with a Mac Mini. It doesn't look particularly accurate: it offers free on-demand access to a Mini if one pays for a month of bandwidth. That's like free bandwidth if one rents a Mini for a month. That's not really how "on-demand" works.

Update 1: In the end, it seems that nobody offers a comparable service. An outfit called Media Temple claims they will offer the first virtual servers using Parallels, OS X Leopard, and some other stuff (in other words, I wonder if there is some caveat that makes them unique, but, without that caveat, someone else may have a usable offering).

After this search, I think that a counterpart to EC2 does not exist for the OS X operating system. It is extraordinarily unlikely that one would exist, offer a scalable solution, and yet be very difficult to find. One could set it up internally, but there's no reseller/vendor offering on-demand, hourly virtual servers. This may be disappointing, but not surprising - apparently iCloud is running on Amazon and Microsoft systems.

Useful tip - if you use __FILE__ and __LINE__ then format your debug as:

"file(line): Your output here"

then when you click on that line in the output window Visual Studio will jump directly to that line of code. An example:

#include <Windows.h>
#include <iostream>
#include <sstream>

void DBOut(const char *file, const int line, const WCHAR *s)
{
    std::wostringstream os_;
    os_ << file << "(" << line << "): ";
    os_ << s;
    OutputDebugStringW(os_.str().c_str());
}

#define DBOUT(s)       DBOut(__FILE__, __LINE__, s)

I wrote a blog post about this so I always knew where I could look it up: https://windowscecleaner.blogspot.co.nz/2013/04/debug-output-tricks-for-visual-studio.html

Short story: The 0 tells the parser it's dealing with a constant (and not an identifier/reserved word). Something is still needed to specify the number base: the x is an arbitrary choice.

Long story: In the 60's, the prevalent programming number systems were decimal and octal — mainframes had 12, 24 or 36 bits per byte, which is nicely divisible by 3 = log2(8).

The BCPL language used the syntax 8 1234 for octal numbers. When Ken Thompson created B from BCPL, he used the 0 prefix instead. This is great because

1. an integer constant now always consists of a single token,
2. the parser can still tell right away it's got a constant,
3. the parser can immediately tell the base (0 is the same in both bases),
4. it's mathematically sane (00005 == 05), and
5. no precious special characters are needed (as in #123).

When C was created from B, the need for hexadecimal numbers arose (the PDP-11 had 16-bit words) and all of the points above were still valid. Since octals were still needed for other machines, 0x was arbitrarily chosen (00 was probably ruled out as awkward).

C# is a descendant of C, so it inherits the syntax.

This can be achieved by using constructor function instead of literal

var o = new function() {
  this.foo = "it";
  this.bar = this.foo + " works"
}

alert(o.bar)

You have to call

setPadding(int left, int top, int right, int bottom)

like so: your_view.setPadding(0,16,0,0)

What you are trying to use is only the getter.

Android studio shows what padding...() actually means in java:

padding example The image shows it only calls getPadding...()

If you want to add a margin to your TextView you will have to LayoutParams:

val params =  LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT)
params.setMargins(int left, int top, int right, int bottom)
your_view.layoutParams = params

Here are two extension methods you can use. They ensure any existing classes are preserved and do not duplicate classes being added.

public static void RemoveCssClass(this WebControl control, String css) {
  control.CssClass = String.Join(" ", control.CssClass.Split(' ').Where(x => x != css).ToArray());
}

public static void AddCssClass(this WebControl control, String css) {
  control.RemoveCssClass(css);
  css += " " + control.CssClass;
  control.CssClass = css;
}

Usage: hlCreateNew.AddCssClass("disabled");

Usage: hlCreateNew.RemoveCssClass("disabled");

Use sorted() with a key as follows -

>>> unsorted_list = [['a','b','c','5','d'],['e','f','g','3','h'],['i','j','k','4','m']]
>>> sorted(unsorted_list, key = lambda x: int(x[3]))
[['e', 'f', 'g', '3', 'h'], ['i', 'j', 'k', '4', 'm'], ['a', 'b', 'c', '5', 'd']]

The lambda returns the fourth element of each of the inner lists and the sorted function uses that to sort those list. This assumes that int(elem) will not fail for the list.

Or use itemgetter (As Ashwini's comment pointed out, this method would not work if you have string representations of the numbers, since they are bound to fail somewhere for 2+ digit numbers)

>>> from operator import itemgetter
>>> sorted(unsorted_list, key = itemgetter(3))
[['e', 'f', 'g', '3', 'h'], ['i', 'j', 'k', '4', 'm'], ['a', 'b', 'c', '5', 'd']]

Here is how I fixed this on my Windows (7) Dev. environment. I assume the following...

• You are Running Command Prompt, Git Bash, Cmder or your favorite Terminal, as an Administrator by right clicking
• Privileges Permissions have been granted for Read/Write (i.e chmod -777)

Okay, let's get to it:

1. Update any packages where a version check is returning a warning ("npm WARN"..) for example...

   npm update -g npm

   npm update -g graceful-fs

2. Next we want to force a cache clean. This is flagged by an '--f' or '-f'..

   npm cache clean --f

3. In Widows Explorer search for the following path

%APPDATA%\npm-cache

And Delete it's contents

4. Start a fresh instance of your Terminal, remembering to 'Right-Click' and 'Run as Administrator', install the packages again.

Hope this helps someone!!

You're storing the .Text properties of the textboxes directly into the database, this doesn't work. The .Text properties are Strings (i.e. simple text) and not typed as DateTime instances. Do the conversion first, then it will work.

Do this for each date parameter:

Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) ) 

Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse or DateTime.TryParseExact, but implementing that is an exercise for the reader.

You need to choose a Property to sort by and pass it as a lambda expression to OrderByDescending

like:

.OrderByDescending(x => x.Delivery.SubmissionDate);

Really, though the first version of your LINQ statement should work. Is t.Delivery.SubmissionDate actually populated with valid dates?

Why so complicated? I think using system API can achieve the same result:

UIImage *largeImage;
CGFloat ratio = 0.4; // you want to get a new image that is 40% the size of large image.
UIImage *newImage = [UIImage imageWithCGImage:largeImage.CGImage
                                        scale:1/ratio
                                  orientation:largeImage.imageOrientation];
// notice the second argument, it is 1/ratio, not ratio.

The only gotcha is you should pass inverse of target ratio as the second argument, as according to the document the second parameter specifies the ratio of original image compared to the new scaled one.

The next() method (offcial doc here) simply move the pointer of the result rows set to the next row (if it can). Anyway you can read this from the offcial doc as well:

Moves the cursor down one row from its current position.

This method return true if there's another row or false otherwise.

The rates that were quoted above are what you would expect to pay US developers; however, I do know some people who have been able to get their apps built for as little as $4,000 by using offshore developers.

Here is a blog post from a group that did this: http://www.lolerapps.com/why-outsourcing-iphone-apps-was-a-no-brainer-for-us

Also, Carla White wrote a fantastic eBook about the process she used to outsource her app called "Inside Secrets to an iPhone App". She talks about how she got a great deal because she was willing to work with a team that was still learning iPhone app development.

So, there are alternatives to the higher price developers discussed above.

Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.

First the actual accounts:

• LocalService account (preferred)

  A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.

  • Name: NT AUTHORITY\LocalService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the LocalService user account
  • has minimal privileges on the local computer
  • presents anonymous credentials on the network
  • SID: S-1-5-19
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-19)

   

• NetworkService account

  Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).

  • NT AUTHORITY\NetworkService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the NetworkService user account
  • has minimal privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers
  • SID: S-1-5-20
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-20)
  • If trying to schedule a task using it, enter NETWORK SERVICE into the Select User or Group dialog

   

• LocalSystem account (dangerous, don't use!)

  Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)

  • Name: .\LocalSystem (can also use LocalSystem or ComputerName\LocalSystem)
  • the account has no password (any password information you provide is ignored)
  • SID: S-1-5-18
  • does not have any profile of its own (HKCU represents the default user)
  • has extensive privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers

   

Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService can still access the internet.

The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).

It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.

In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).

In Windows Server 2003 you cannot run a scheduled task as

• NT_AUTHORITY\LocalService (aka the Local Service account), or
• NT AUTHORITY\NetworkService (aka the Network Service account).

That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.

A service running as NetworkService presents the machine credentials on the network. This means that if your computer was called mango, it would present as the machine account MANGO$:

Non-numpy functions like math.abs() or math.log10() don't play nicely with numpy arrays. Just replace the line raising an error with:

m = np.log10(np.abs(x))

Apart from that the np.polyfit() call will not work because it is missing a parameter (and you are not assigning the result for further use anyway).

You can use a select into statement. See more at W3Schools.

Update: User cphyc has kindly created a Github repository for the code in this answer (see here), and bundled the code into a package which may be installed using pip install matplotlib-label-lines.

Pretty Picture:

In matplotlib it's pretty easy to label contour plots (either automatically or by manually placing labels with mouse clicks). There does not (yet) appear to be any equivalent capability to label data series in this fashion! There may be some semantic reason for not including this feature which I am missing.

Regardless, I have written the following module which takes any allows for semi-automatic plot labelling. It requires only numpy and a couple of functions from the standard math library.

Description

The default behaviour of the labelLines function is to space the labels evenly along the x axis (automatically placing at the correct y-value of course). If you want you can just pass an array of the x co-ordinates of each of the labels. You can even tweak the location of one label (as shown in the bottom right plot) and space the rest evenly if you like.

In addition, the label_lines function does not account for the lines which have not had a label assigned in the plot command (or more accurately if the label contains '_line').

Keyword arguments passed to labelLines or labelLine are passed on to the text function call (some keyword arguments are set if the calling code chooses not to specify).

Issues

• Annotation bounding boxes sometimes interfere undesirably with other curves. As shown by the 1 and 10 annotations in the top left plot. I'm not even sure this can be avoided.
• It would be nice to specify a y position instead sometimes.
• It's still an iterative process to get annotations in the right location
• It only works when the x-axis values are floats

Gotchas

• By default, the labelLines function assumes that all data series span the range specified by the axis limits. Take a look at the blue curve in the top left plot of the pretty picture. If there were only data available for the x range 0.5-1 then then we couldn't possibly place a label at the desired location (which is a little less than 0.2). See this question for a particularly nasty example. Right now, the code does not intelligently identify this scenario and re-arrange the labels, however there is a reasonable workaround. The labelLines function takes the xvals argument; a list of x-values specified by the user instead of the default linear distribution across the width. So the user can decide which x-values to use for the label placement of each data series.

Also, I believe this is the first answer to complete the bonus objective of aligning the labels with the curve they're on. :)

label_lines.py:

from math import atan2,degrees
import numpy as np

#Label line with line2D label data
def labelLine(line,x,label=None,align=True,**kwargs):

    ax = line.axes
    xdata = line.get_xdata()
    ydata = line.get_ydata()

    if (x < xdata[0]) or (x > xdata[-1]):
        print('x label location is outside data range!')
        return

    #Find corresponding y co-ordinate and angle of the line
    ip = 1
    for i in range(len(xdata)):

    if xvals is None:
        xmin,xmax = ax.get_xlim()
        xvals = np.linspace(xmin,xmax,len(labLines)+2)[1:-1]

    for line,x,label in zip(labLines,xvals,labels):
        labelLine(line,x,label,align,**kwargs)

Test code to generate the pretty picture above:

from matplotlib import pyplot as plt
from scipy.stats import loglaplace,chi2

from labellines import *

X = np.linspace(0,1,500)
A = [1,2,5,10,20]
funcs = [np.arctan,np.sin,loglaplace(4).pdf,chi2(5).pdf]

plt.subplot(221)
for a in A:
    plt.plot(X,np.arctan(a*X),label=str(a))

labelLines(plt.gca().get_lines(),zorder=2.5)

plt.subplot(222)
for a in A:
    plt.plot(X,np.sin(a*X),label=str(a))

labelLines(plt.gca().get_lines(),align=False,fontsize=14)

plt.subplot(223)
for a in A:
    plt.plot(X,loglaplace(4).pdf(a*X),label=str(a))

xvals = [0.8,0.55,0.22,0.104,0.045]
labelLines(plt.gca().get_lines(),align=False,xvals=xvals,color='k')

plt.subplot(224)
for a in A:
    plt.plot(X,chi2(5).pdf(a*X),label=str(a))

lines = plt.gca().get_lines()
l1=lines[-1]
labelLine(l1,0.6,label=r'$Re=${}'.format(l1.get_label()),ha='left',va='bottom',align = False)
labelLines(lines[:-1],align=False)

plt.show()

I have a very simple solution for this ! //HTML

<div>
<div id="left">
    left
</div>
<div id="right">
    right
</div>

//CSS

#left {
float:left;
width:50%;
position:relative;
background-color:red;
}
#right {
position:relative;
background-color:#00FF00;}

Just run on ports above 1024 , anything below is privileged, its the same deal with Linux, i use 5000 for example on wins without any UAC priv escalation.

using pymsql if it helps

import pymysql
import csv
db = pymysql.connect("localhost","root","12345678","data" )

cursor = db.cursor()
csv_data = csv.reader(open('test.csv'))
next(csv_data)
for row in csv_data:
    cursor.execute('INSERT INTO PM(col1,col2) VALUES(%s, %s)',row)

db.commit()
cursor.close()

Try MtPutty, you can automate the ssh login in it. Its a great tool especially if you need to login to multiple servers many times. Try it here

Another tool worth trying is TeraTerm. Its really easy to use for the ssh automation stuff. You can get it here. But my favorite one is always MtPutty.

You could subscribe for the .click event for the links and change the contents of the div using the .html method:

$('.click').click(function() {
    // get the contents of the link that was clicked
    var linkText = $(this).text();

    // replace the contents of the div with the link text
    $('#content-container').html(linkText);

    // cancel the default action of the link by returning false
    return false;
});

Note however that if you replace the contents of this div the click handler that you have assigned will be destroyed. If you intend to inject some new DOM elements inside the div for which you need to attach event handlers, this attachments should be performed inside the .click handler after inserting the new contents. If the original selector of the event is preserved you may also take a look at the .delegate method to attach the handler.

    Object object = new Object();

    // First way
    List objects1 = new ArrayList<Object>();
    objects1.add(object);

    // second way
    List<Object> objects2 = Arrays.asList(object);

    // Third way
    List<Object> objects3 = Collections.singletonList(object);

I am also adding an answer that augments this a little bit because I came to this entry when searching for an answer, and this had almost what I needed, but I needed a bit more, which I got via @MrFlik 's answer and the R lazyeval vignettes.

I wanted to make a function that could take a dataframe and a vector of column names (as strings) that I want to be converted from a string to a Date object. I couldn't figure out how to make as.Date() take an argument that is a string and convert it to a column, so I did it as shown below.

Below is how I did this via SE mutate (mutate_()) and the .dots argument. Criticisms that make this better are welcome.

library(dplyr)

dat <- data.frame(a="leave alone",
                  dt="2015-08-03 00:00:00",
                  dt2="2015-01-20 00:00:00")

# This function takes a dataframe and list of column names
# that have strings that need to be
# converted to dates in the data frame
convertSelectDates <- function(df, dtnames=character(0)) {
    for (col in dtnames) {
        varval <- sprintf("as.Date(%s)", col)
        df <- df %>% mutate_(.dots= setNames(list(varval), col))
    }
    return(df)
}

dat <- convertSelectDates(dat, c("dt", "dt2"))
dat %>% str

I got the same problem. I did all those steps mentioned in all above comments. It didn't work. But when I closed Visual Studio, deleted ".vs" folder (in the solution folder) then reopened Visual Studio. It now works like a charm. The problem is gone.

You can truncate the date part:

select * from table1 where trunc(field1) = to_date('2012-01-01', 'YYYY-MM-DD')

The trouble with this approach is that any index on field1 wouldn't be used due to the function call.

Alternatively (and more index friendly)

select * from table1 
 where field1 >= to_timestamp('2012-01-01', 'YYYY-MM-DD') 
   and field1 < to_timestamp('2012-01-02', 'YYYY-MM-DD')

The idea is, using the command cmd ipconfig /all and extract only the address mac.

Which his index $pmac+33.

And the size of mac is 17.

<?php
ob_start();
system('ipconfig /all');
$mycom=ob_get_contents();
ob_clean();
$findme = 'physique';
$pmac = strpos($mycom, $findme);
$mac=substr($mycom,($pmac+33),17);
echo $mac;
?>

To match either / or end of content, use (/|\z)

This only applies if you are not using multi-line matching (i.e. you're matching a single URL, not a newline-delimited list of URLs).

To put that with an updated version of what you had:

/(\S+?)/(\d{4}-\d{2}-\d{2})-(\d+)(/|\z)

Note that I've changed the start to be a non-greedy match for non-whitespace ( \S+? ) rather than matching anything and everything ( .* )

Just a note for php developers (I lack the necessary stackoverflow points to post this as a comment) ... the automagic (and silent) conversion to TINYINT means that php retrieves a value from a "BOOLEAN" column as a "0" or "1", not the expected (by me) true/false.

A developer who is looking at the SQL used to create a table and sees something like: "some_boolean BOOLEAN NOT NULL DEFAULT FALSE," might reasonably expect to see true/false results when a row containing that column is retrieved. Instead (at least in my version of PHP), the result will be "0" or "1" (yes, a string "0" or string "1", not an int 0/1, thank you php).

It's a nit, but enough to cause unit tests to fail.

The easiest solution to workaround this is to create 'temporary' input with type submit and trigger click:

var submitInput = $("<input type='submit' />");
$("#aspnetForm").append(submitInput);
submitInput.trigger("click");

Quote from official documentation as of August 2013:

User-created libraries as of version 0017 go in a subdirectory of your default sketch directory. For example, on OSX, the new directory would be ~/Documents/Arduino/libraries/. On Windows, it would be My Documents\Arduino\libraries\. To add your own library, create a new directory in the libraries directory with the name of your library. The folder should contain a C or C++ file with your code and a header file with your function and variable declarations. It will then appear in the Sketch | Import Library menu in the Arduino IDE.

To remove a library, stop the Arduino IDE and remove the library directory from the aforementioned location.
