I had trouble with touchend handler firing continuously while the user was dragging a finger around. I don't know if that's due to something I'm doing wrong or not but I rewired this to accumulate moves with touchmove and touchend actually fires the callback.

I also needed to have a large number of these instances and so I added enable/disable methods.

And a threshold where a short swipe doesn't fire. Touchstart zero's the counters each time.

You can change the target_node on the fly. Enable on creation is optional.

To answer your question, firstly I would strongly recommend looking at the Documentation.

Without overriding the equals() method, it will act like "==". When you use the "==" operator on objects, it simply checks to see if those pointers refer to the same object. Not if their members contain the same value.

We override to keep our code clean, and abstract the comparison logic from the If statement, into the object. This is considered good practice and takes advantage of Java's heavily Object Oriented Approach.

Why use the canvas to resize images? Modern browsers all use bicubic interpolation — the same process used by Photoshop (if you're doing it right) — and they do it faster than the canvas process. Just specify the image size you want (use only one dimension, height or width, to resize proportionally).

This is supported by most browsers, including later versions of IE. Earlier versions may require browser-specific CSS.

A simple function (using jQuery) to resize an image would be like this:

function resizeImage(img, percentage) {
    var coeff = percentage/100,
        width = $(img).width(),
        height = $(img).height();

    return {"width": width*coeff, "height": height*coeff}           
}

Then just use the returned value to resize the image in one or both dimensions.

Obviously there are different refinements you could make, but this gets the job done.

Paste the following code into the console of this page and watch what happens to the gravatars:

function resizeImage(img, percentage) {
    var coeff = percentage/100,
        width = $(img).width(),
        height = $(img).height();

    return {"width": width*coeff, "height": height*coeff}           
}

$('.user-gravatar32 img').each(function(){
  var newDimensions = resizeImage( this, 150);
  this.style.width = newDimensions.width + "px";
  this.style.height = newDimensions.height + "px";
});

You can't add image from desktop to UIimageView, you only can add image (dragging) into project folders and then select the name image into UIimageView properties (inspector).

Tutorial on how to do that: http://conecode.com/news/2011/06/ios-tutorial-creating-an-image-view-uiimageview/

A web application involving lot of user interaction with many AJAX requests, which needs to be changed from time to time, and which runs in real time (such as Facebook or StackOverflow) ought to use an MVC framework such as Backbone.js. It's the best way to build good code.

If the application is only small though, then Backbone.js is overkill, especially for first time users.

Backbone gives you client side MVC, and all the advantages implied by this.

From RFC 6750, Section 1.2:

Bearer Token

A security token with the property that any party in possession of the token (a "bearer") can use the token in any way that any other party in possession of it can. Using a bearer token does not require a bearer to prove possession of cryptographic key material (proof-of-possession).

The Bearer Token or Refresh token is created for you by the Authentication server. When a user authenticates your application (client) the authentication server then goes and generates for your a Bearer Token (refresh token) which you can then use to get an access token.

The Bearer Token is normally some kind of cryptic value created by the authentication server, it isn't random it is created based upon the user giving you access and the client your application getting access.

I am using this, which works for me.

I know I am late to answer the function but jquery have a in build function to do this

if(jQuery.type(val) === "undefined"){
    //Some code goes here
}

Refer jquery API document of jquery.type https://api.jquery.com/jQuery.type/ for the same.

edit: sorry, I no longer have the code mentioned below. It was a neat solution, although complex.

I posted a sample project describing how to use PropertyDescriptor and lambda delegates with dynamic ObservableCollection and DynamicObject to populate a grid with strongly-typed column definitions.

Columns can be added/removed at runtime dynamically. If your data is not a object with known type, you could create a data structure that would enable access by any number of columns and specify a PropertyDescriptor for each "column".

For example:

IList<string> ColumnNames { get; set; }
//dict.key is column name, dict.value is value
Dictionary<string, string> Rows { get; set; }

You can define columns this way:

var descriptors= new List<PropertyDescriptor>();
//retrieve column name from preprepared list or retrieve from one of the items in dictionary
foreach(var columnName in ColumnNames)
    descriptors.Add(new DynamicPropertyDescriptor<Dictionary, string>(ColumnName, x => x[columnName]))
MyItemsCollection = new DynamicDataGridSource(Rows, descriptors) 

Or even better, in case of some real objects

public class User 
{
    public string FirstName { get; set; }
    public string LastName{ get; set; }
    ...
}

You can specify columns strongly typed (related to your data model):

var propertyDescriptors = new List<PropertyDescriptor>
{
    new DynamicPropertyDescriptor<User, string>("First name", x => x.FirstName ),
    new DynamicPropertyDescriptor<User, string>("Last name", x => x.LastName ),
    ...
}

var users = retrieve some users

Users = new DynamicDataGridSource<User>(users, propertyDescriptors, PropertyChangedListeningMode.Handler);

Then you just bind to Users collections and columns are autogenerated as you speficy them. Strings passed to property descriptors are names for column headers. At runtime you can add more PropertyDescriptors to 'Users' add another column to the grid.

You could use

options(warn=-1)

But note that turning off warning messages globally might not be a good idea.

To turn warnings back on, use

options(warn=0)

(or whatever your default is for warn, see this answer)

You can do the following command to see the username you are logged in with and the registry used:

docker system info | grep -E 'Username|Registry'

My last adventure with MSDTC and this error today turned out to be a DNS issue. You're on the right track asking if the machines are on the same domain, EBarr. Terrific list for this issue, by the way!

My situation: I needed a server in a child domain to be able to run distributed transactions against a server in the parent domain through a firewall. I've used linked servers quite a bit over the years, so I had all the usual settings in SQL for a linked server and in MSDTC that Ian documented so nicely above. I set up MSDTC with a range of TCP ports (5000-5200) to use on both servers, and arranged for a firewall hole between the boxes for ports 1433 and 5000-5200. That should have worked. The linked server tested OK and I could query the remote SQL server via the linked server nicely, but I couldn't get it to allow a distributed transaction. I could even see a connection on the QA server from the DEV server, but something wasn't making the trip back.

I could PING the DEV server from QA using a FQDN like: PING DEVSQL.dev.domain.com

I could not PING the DEV server with just the machine name: PING DEVSQL

The DEVSQL server was supposed to be a member of both domains, but the name wasn't resolving in the parent domain's DNS... something had happened to the machine account for DEVSQL in the parent domain. Once we added DEVSQL to the DNS for the parent domain, and "PING DEVSQL" worked from the remote QA server, this issue was resolved for us.

I hope this helps!

$cmd would just replace the variable with it's value to be executed on command line. eval "$cmd" does variable expansion & command substitution before executing the resulting value on command line

The 2nd method is helpful when you wanna run commands that aren't flexible eg.
for i in {$a..$b}
format loop won't work because it doesn't allow variables.
In this case, a pipe to bash or eval is a workaround.

Tested on Mac OSX 10.6.8, Bash 3.2.48

I think you should use git pull --rebase when collaborating with others on the same branch. You are in your work ? commit ? work ? commit cycle, and when you decide to push your work your push is rejected, because there's been parallel work on the same branch. At this point I always do a pull --rebase. I do not use squash (to flatten commits), but I rebase to avoid the extra merge commits.

As your Git knowledge increases you find yourself looking a lot more at history than with any other version control systems I've used. If you have a ton of small merge commits, it's easy to lose focus of the bigger picture that's happening in your history.

This is actually the only time I do rebasing(*), and the rest of my workflow is merge based. But as long as your most frequent committers do this, history looks a whole lot better in the end.

(*) While teaching a Git course, I had a student arrest me on this, since I also advocated rebasing feature branches in certain circumstances. And he had read this answer ;) Such rebasing is also possible, but it always has to be according to a pre-arranged/agreed system, and as such should not "always" be applied. And at that time I usually don't do pull --rebase either, which is what the question is about ;)

It looks like you override public Map<String, String> getHeaders(), defined in Request, to return your desired HTTP headers.

For to use looping get all arguments and in pure batch:

Obs: For using without: ?*&<>

@echo off && setlocal EnableDelayedExpansion

 for %%Z in (%*)do set "_arg_=%%Z" && set/a "_cnt+=1+0" && (
     call set "_arg_[!_cnt!]=!_arg_!" && for /l %%l in (!_cnt! 1 !_cnt!
     )do echo/ The argument n:%%l is: !_arg_[%%l]!
 )

goto :eof 

Your code is ready to do something with the argument number where it needs, like...

 @echo off && setlocal EnableDelayedExpansion

 for %%Z in (%*)do set "_arg_=%%Z" && set/a "_cnt+=1+0" && call set "_arg_[!_cnt!]=!_arg_!"
 
 fake-command /u !_arg_[1]! /p !_arg_[2]! > test-log.txt
 

There are mainly two ways to use JDBC - using Windows authentication and SQL authentication. SQL authentication is probably the easiest. What you can do is something like:

String userName = "username";
String password = "password";

String url = "jdbc:sqlserver://MYPC\\SQLEXPRESS;databaseName=MYDB";

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn = DriverManager.getConnection(url, userName, password);

after adding sqljdbc4.jar to the build path.

For Window authentication you can do something like:

String url = "jdbc:sqlserver://MYPC\\SQLEXPRESS;databaseName=MYDB;integratedSecurity=true";
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn = DriverManager.getConnection(url);

and then add the path to sqljdbc_auth.dll as a VM argument (still need sqljdbc4.jar in the build path).

Please take a look here for a short step-by-step guide showing how to connect to SQL Server from Java using jTDS and JDBC should you need more details. Hope it helps!

I believe you should escape the dot. Try:

String filename = "D:/some folder/001.docx";
String extensionRemoved = filename.split("\\.")[0];

Otherwise dot is interpreted as any character in regular expressions.

Go to obj folder in you app folder, then Debug. In there delete the manifest file and build again. It worked for me.

public class Test {
    public static void main(String args[]) {
    String s = "pre/fix/dir1/dir2/dir3/dir4/..";
    String prefix = "pre/fix";
    String[] tokens = s.substring(prefix.length()).split("/");
    for (int i=0; i<tokens.length; i++) {
        System.out.println(tokens[i]);
    }
    }

}

Actually, valueOf uses parseInt internally. The difference is parseInt returns an int primitive while valueOf returns an Integer object. Consider from the Integer.class source:

public static int parseInt(String s) throws NumberFormatException {
    return parseInt(s, 10);
}

public static Integer valueOf(String s, int radix) throws NumberFormatException {
    return Integer.valueOf(parseInt(s, radix));
}

public static Integer valueOf(String s) throws NumberFormatException {
    return Integer.valueOf(parseInt(s, 10));
}

As for parsing with a comma, I'm not familiar with one. I would sanitize them.

int million = Integer.parseInt("1,000,000".replace(",", ""));

I am using JDK 7 for maven project and I used -Dhttps.protocols=TLSv1.2 as argument in JRE. It has allowed to download all maven repository which were failing earlier.

To complement Michael's answer, and according to this answer, a safe way to deal with the problem is to use the following arguments:

-XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled -XX:+UseConcMarkSweepGC

I also had trouble overruling a dependency in a third party library. I used scot's approach with the exclusion but I also added the dependency with the newer version in the pom. (I used Maven 3.3.3)

So for the stAX example it would look like this:

<dependency>
  <groupId>a.group</groupId>
  <artifactId>a.artifact</artifactId>
  <version>a.version</version>
  <exclusions>
    <!--  STAX comes with Java 1.6 -->
    <exclusion>
      <artifactId>stax-api</artifactId>
      <groupId>javax.xml.stream</groupId>
    </exclusion>
    <exclusion>
      <artifactId>stax-api</artifactId>
      <groupId>stax</groupId>
    </exclusion>
  </exclusions>
<dependency>

<dependency>
    <groupId>javax.xml.stream</groupId>
    <artifactId>stax-api</artifactId>
    <version>1.0-2</version>

Swift 5 version

The answers given here are either outdated or incorrect because they don't take into account the following:

1. The pixel size of the image can differ from its point size that is returned by image.size.width/image.size.height.
2. There can be various layouts used by pixel components in the image, such as BGRA, ABGR, ARGB etc. or may not have an alpha component at all, such as BGR and RGB. For example, UIView.drawHierarchy(in:afterScreenUpdates:) method can produce BGRA images.
3. Color components can be premultiplied by the alpha for all pixels in the image and need to be divided by alpha in order to restore the original color.
4. For memory optimization used by CGImage, the size of a pixel row in bytes can be greater than the mere multiplication of the pixel width by 4.

The code below is to provide a universal Swift 5 solution to get the UIColor of a pixel for all such special cases. The code is optimized for usability and clarity, not for performance.

"As with bootstrap’s own plugins, datepicker provides a data-api that can be used to instantiate datepickers without the need for custom javascript..."

Boostrap DatePicker Documentation

Maybe you want to set format without DatePicker instance, for that, you have to add the property data-date-format="DateFormat" to main Div tag, for example:

<div class="input-group date" data-provide="datepicker" data-date-format="yyyy-mm-dd">
    <div class="input-group-addon">
        <span class="glyphicon glyphicon-th"></span>
    </div>

    <input type="text" name="YourName" id="YourId" class="YourClass">
</div>

Encrypting using openssl_encrypt() The openssl_encrypt function provides a secured and easy way to encrypt your data.

In the script below, we use the AES128 encryption method, but you may consider other kind of encryption method depending on what you want to encrypt.

<?php
$message_to_encrypt = "Yoroshikune";
$secret_key = "my-secret-key";
$method = "aes128";
$iv_length = openssl_cipher_iv_length($method);
$iv = openssl_random_pseudo_bytes($iv_length);

$encrypted_message = openssl_encrypt($message_to_encrypt, $method, $secret_key, 0, $iv);

echo $encrypted_message;
?>

Here is an explanation of the variables used :

message_to_encrypt : the data you want to encrypt secret_key : it is your ‘password’ for encryption. Be sure not to choose something too easy and be careful not to share your secret key with other people method : the method of encryption. Here we chose AES128. iv_length and iv : prepare the encryption using bytes encrypted_message : the variable including your encrypted message

Decrypting using openssl_decrypt() Now you encrypted your data, you may need to decrypt it in order to re-use the message you first included into a variable. In order to do so, we will use the function openssl_decrypt().

<?php
$message_to_encrypt = "Yoroshikune";
$secret_key = "my-secret-key";
$method = "aes128";
$iv_length = openssl_cipher_iv_length($method);
$iv = openssl_random_pseudo_bytes($iv_lenght);
$encrypted_message = openssl_encrypt($message_to_encrypt, $method, $secret_key, 0, $iv);

$decrypted_message = openssl_decrypt($encrypted_message, $method, $secret_key, 0, $iv);

echo $decrypted_message;
?>

The decrypt method proposed by openssl_decrypt() is close to openssl_encrypt().

The only difference is that instead of adding $message_to_encrypt, you will need to add your already encrypted message as the first argument of openssl_decrypt().

That is all you have to do.

Here's a Swift version:

func durationsBySecond(seconds s: Int) -> (days:Int,hours:Int,minutes:Int,seconds:Int) {
    return (s / (24 * 3600),(s % (24 * 3600)) / 3600, s % 3600 / 60, s % 60)
}

Can be used like this:

let (d,h,m,s) = durationsBySecond(seconds: duration)
println("time left: \(d) days \(h) hours \(m) minutes \(s) seconds")

I use following code, found somewhere in the internet don't remember the source though.

    var allText;
    var rawFile = new XMLHttpRequest();
    rawFile.open("GET", file, false);
    rawFile.onreadystatechange = function () {
        if (rawFile.readyState === 4) {
            if (rawFile.status === 200 || rawFile.status == 0) {
                allText = rawFile.responseText;
            }
        }
    }
    rawFile.send(null);
    return JSON.parse(allText);

Hope this helps :-)

You need to do custom SQL as exemplified in this snippet:

Custom SQL via subquery

Or in a custom manager as shown in the online Django docs:

Adding extra Manager methods

Since tooltip is not initialized automatically, you can make changes in your initialization of the tooltip. I did mine like this:

$(document).ready(function() {
    $('body').tooltip({
        selector: "[data-tooltip=tooltip]",
        container: "body"
    });
});

with this markup:

<button type="button" data-target="#myModal" data-toggle="modal" data-tooltip="tooltip" class="btn btn-info" title="Your tooltip">Text here</button>

Notice the data-tooltip.

Update

Or simply,

$('[data-tooltip="tooltip"]').tooltip();

1. Delete rows 1 and 2 so that your headings are on row 1

2. Put this in a macro (IT WILL CHECK THROUGH ROW 75000, YOU CAN LOWER THE NUMBER IF YOU WOULD LIKE

   Columns("E:E").Select Selection.AutoFilter ActiveSheet.Range("$E$1:$E$75000").AutoFilter Field:=1, Criteria1:="none" Range("E2:E75000").SpecialCells(xlCellTypeVisible).Select Selection.EntireRow.Delete ActiveSheet.Cells.EntireRow.Hidden = False ActiveSheet.Range("$E$1:$E$75000").AutoFilter Field:=1 Columns("E:E").Select Selection.AutoFilter Range("E2").Select Range("A1").Select

As other answers mentioned, git config -l lists all your configuration details from your config file. Here's a partial example of that output for my configuration:

...
alias.force=push -f
alias.wd=diff --color-words
alias.shove=push -f
alias.gitignore=!git ls-files -i --exclude-from=.gitignore | xargs git rm --cached
alias.branches=!git remote show origin | grep \w*\s*(new^|tracked) -E
core.repositoryformatversion=0
core.filemode=false
core.bare=false
...

So we can grep out the alias lines, using git config -l | grep alias:

alias.force=push -f
alias.wd=diff --color-words
alias.shove=push -f
alias.gitignore=!git ls-files -i --exclude-from=.gitignore | xargs git rm --cached
alias.branches=!git remote show origin | grep \w*\s*(new^|tracked) -E

We can make this prettier by just cutting out the alias. part of each line, leaving us with this command:

git config -l | grep alias | cut -c 7-

Which prints:

force=push -f
wd=diff --color-words
shove=push -f
gitignore=!git ls-files -i --exclude-from=.gitignore | xargs git rm --cached
branches=!git remote show origin | grep \w*\s*(new^|tracked) -E

Lastly, don't forget to add this as an alias:

git config --global alias.la "!git config -l | grep alias | cut -c 7-"

Enjoy!

You can retrieve the series through slicing your dataframe using one of these two methods:

http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.iloc.html http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.loc.html

import pandas as pd
import numpy as np
df = pd.DataFrame(data=np.random.randn(1,8))

series1=df.iloc[0,:]
type(series1)
pandas.core.series.Series

Why can't you do it? Because the language doesn't allow you to initializa a base class' members in the derived class' initializer list.

How can you get this done? Like this:

class A
{
public:
    A(int a, int b) : a_(a), b_(b) {};
    int a_, b_;
};

class B : public A
{
public:
    B() : A(0,0) 
    {
    }
};

For Windows:

• Ctrl+K,Ctrl+U for UPPERCASE.
• Ctrl+K,Ctrl+L for lowercase.

Method 1 (Two keys pressed at a time)

1. Press Ctrl and hold.
2. Now press K, release K while holding Ctrl. (Do not release the Ctrl key)
3. Immediately, press U (for uppercase) OR L (for lowercase) with Ctrl still being pressed, then release all pressed keys.

Method 2 (3 keys pressed at a time)

1. Press Ctrl and hold.
2. Now press K.
3. Without releasing Ctrl and K, immediately press U (for uppercase) OR L (for lowercase) and release all pressed keys.

Please note: If you press and hold Ctrl+K for more than two seconds it will start deleting text so try to be quick with it.

I use the above shortcuts, and they work on my Windows system.

you should declare label first use this :

    Select Case parameter 
        Case "userID"
                    ' does something here.
            Case "packageID"
                    ' does something here.
            Case "mvrType" 
                    If otherFactor Then 
                            ' does something here. 
                    Else 
                            GoTo else
                    End If 

            Case Else 
else :
                    ' does some processing... 
                    Exit Select 
    End Select

In your Eclipse editor screen, try Control + Shift + R buttons.

Also you can try to formulate your answer in the form of a SELECT CASE Statement. You can then later create simple if then's that use your results if needed as you have narrowed down the possibilities.

SELECT @Result =   
CASE @inputParam   
WHEN 1 THEN 1   
WHEN 2 THEN 2   
WHEN 3 THEN 1   
ELSE 4   
END  

IF @Result = 1   
BEGIN  
...  
END  

IF @Result = 2   
BEGIN   
....  
END  

IF @Result = 4   
BEGIN   
//Error handling code   
END   

Xcode8 swift3.1:

1. Set webView height to 0 first.
2. In webViewDidFinishLoad Delegate:

let height = webView.scrollView.contentSize.height

Without step1, if webview.height > actual contentHeight, step 2 will return webview.height but not contentsize.height.

contentCompressionResistancePriority – The view with the lowest value gets truncated when there is not enough space to fit everything’s intrinsicContentSize

contentHuggingPriority – The view with the lowest value gets expanded beyond its intrinsicContentSize when there is leftover space to fill

You can format your output in Java as described in below code snippet.

public class TestFormat {

    public static void main(String[] args) {
      long n = 461012;
      System.out.format("%d%n", n);      //  -->  "461012"
      System.out.format("%08d%n", n);    //  -->  "00461012"
      System.out.format("%+8d%n", n);    //  -->  " +461012"
      System.out.format("%,8d%n", n);    // -->  " 461,012"
      System.out.format("%+,8d%n%n", n); //  -->  "+461,012"
   }
}

SQL Server Express doesn't include SQL Server Agent, so it's not possible to just create SQL Agent jobs.

What you can do is:
You can create jobs "manually" by creating batch files and SQL script files, and running them via Windows Task Scheduler.
For example, you can backup your database with two files like this:

backup.bat:

sqlcmd -i backup.sql

backup.sql:

backup database TeamCity to disk = 'c:\backups\MyBackup.bak'

Just put both files into the same folder and exeute the batch file via Windows Task Scheduler.

The first file is just a Windows batch file which calls the sqlcmd utility and passes a SQL script file.
The SQL script file contains T-SQL. In my example, it's just one line to backup a database, but you can put any T-SQL inside. For example, you could do some UPDATE queries instead.

If the jobs you want to create are for backups, index maintenance or integrity checks, you could also use the excellent Maintenance Solution by Ola Hallengren.

It consists of a bunch of stored procedures (and SQL Agent jobs for non-Express editions of SQL Server), and in the FAQ there’s a section about how to run the jobs on SQL Server Express:

How do I get started with the SQL Server Maintenance Solution on SQL Server Express?

SQL Server Express has no SQL Server Agent. Therefore, the execution of the stored procedures must be scheduled by using cmd files and Windows Scheduled Tasks. Follow these steps.

SQL Server Express has no SQL Server Agent. Therefore, the execution of the stored procedures must be scheduled by using cmd files and Windows Scheduled Tasks. Follow these steps.

1. Download MaintenanceSolution.sql.

2. Execute MaintenanceSolution.sql. This script creates the stored procedures that you need.

3. Create cmd files to execute the stored procedures; for example:
   sqlcmd -E -S .\SQLEXPRESS -d master -Q "EXECUTE dbo.DatabaseBackup @Databases = 'USER_DATABASES', @Directory = N'C:\Backup', @BackupType = 'FULL'" -b -o C:\Log\DatabaseBackup.txt

4. In Windows Scheduled Tasks, create tasks to call the cmd files.

5. Schedule the tasks.

6. Start the tasks and verify that they are completing successfully.

The compilation problem only occurs for me (gcc 4.3, ubuntu 8.10) if the three variables are global. The problem is that C doesn't work like a script languages, so you cannot take for granted that the initialization of u and t occur after the one of s. That's why you get a compilation error. Now, you cannot initialize t and y they way you did it before, that's why you will need a char*. The code that do the work is the following:

#include <stdio.h>
#include <stdlib.h>

#define STR "ABCD"

const char s[] = STR;
char* t;
char* u;

void init(){
    t = malloc(sizeof(STR)-1);
    t[0] = s[0];
    t[1] = s[1];
    t[2] = s[2];
    t[3] = s[3];


    u = malloc(sizeof(STR)-1);
    u[0] = s[3];
    u[1] = s[2];
    u[2] = s[1];
    u[3] = s[0];
}

int main(void) {
    init();
    puts(t);
    puts(u);

    return EXIT_SUCCESS;
}

In case you need this to write a .properties file you can just add the Strings into a Properties object and then save it to a file. It will take care for the conversion.

This is from Apple doc

Classes and structures must set all of their stored properties to an appropriate initial value by the time an instance of that class or structure is created. Stored properties cannot be left in an indeterminate state.

You get the error message Class "HomeCell" has no initializers because your variables is in an indeterminate state. Either you create initializers or you make them optional types, using ! or ?

If you're using pip to install your modules, just pip show $module the location is returned.

Try this solution for remove border around the button. Add this code in css.

Try

button:focus{
outline:0px;
}

If not works then use below.

button:focus{
 outline:none !important;
 }

You can use this way either :

Add this line to your recyclerView xml file :

android:nestedScrollingEnabled="false"

Or in java code :

RecyclerView.setNestedScrollingEnabled(false);

Hope this helped .

I had the same problem and I chosed to create my own encoder, which will cope by themself with recursion.

I created classes which implements Symfony\Component\Serializer\Normalizer\NormalizerInterface, and a service which holds every NormalizerInterface.

#This is the NormalizerService

class NormalizerService 
{

   //normalizer are stored in private properties
   private $entityOneNormalizer;
   private $entityTwoNormalizer;

   public function getEntityOneNormalizer()
   {
    //Normalizer are created only if needed
    if ($this->entityOneNormalizer == null)
        $this->entityOneNormalizer = new EntityOneNormalizer($this); //every normalizer keep a reference to this service

    return $this->entityOneNormalizer;
   }

   //create a function for each normalizer



  //the serializer service will also serialize the entities 
  //(i found it easier, but you don't really need it)
   public function serialize($objects, $format)
   {
     $serializer = new Serializer(
            array(
                $this->getEntityOneNormalizer(),
                $this->getEntityTwoNormalizer()
            ),
            array($format => $encoder) );

     return $serializer->serialize($response, $format);
}

An example of a Normalizer :

use Symfony\Component\Serializer\Normalizer\NormalizerInterface;

class PlaceNormalizer implements NormalizerInterface {

private $normalizerService;

public function __construct($normalizerService)
{
    $this->service = normalizerService;

}

public function normalize($object, $format = null) {
    $entityTwo = $object->getEntityTwo();
    $entityTwoNormalizer = $this->service->getEntityTwoNormalizer();

    return array(
        'param' => object->getParam(),
        //repeat for every parameter
        //!!!! this is where the entityOneNormalizer dealt with recursivity
        'entityTwo' => $entityTwoNormalizer->normalize($entityTwo, $format.'_without_any_entity_one') //the 'format' parameter is adapted for ignoring entity one - this may be done with different ways (a specific method, etc.)
    );
}

}

In a controller :

$normalizerService = $this->get('normalizer.service'); //you will have to configure services.yml
$json = $normalizerService->serialize($myobject, 'json');
return new Response($json);

The complete code is here : https://github.com/progracqteur/WikiPedale/tree/master/src/Progracqteur/WikipedaleBundle/Resources/Normalizer

Use jQuery. Keep your checkbox elements hidden and create a list like this:

<ul id="list">
    <li><a href="javascript:void(0)" id="link1">Happy face</a></li>
    <li><a href="javascript:void(0)" id="link2">Sad face</a></li>
</ul>

<form action="file.php" method="post">
    <!-- More code -->
    <input type="radio" id="option1" name="radio1" value="happy" style="display:none"/>
    <input type="radio" id="option2" name="radio1" value="sad" style="display:none"/>
    <!-- More code -->
</form>

<script type="text/javascript">
$("#list li a").click(function() {
    $('#list .active').removeClass("active");
    var id = this.id;
    var newselect = id.replace('link', 'option');
    $('#'+newselect).attr('checked', true);
    $(this).addClass("active").parent().addClass("active");
    return false;
});
</script>

This code would add the checked attribute to your radio inputs in the background and assign class active to your list elements. Do not use inline styles of course, don't forget to include jQuery and everything should run out of the box after you customize it.

Others do not exactly reload. They keep values inside text boxes.

I couldn't find a neat way in the end so I went for create a directory called local_modules and then added this bashscript to the package.json in scripts->preinstall

#!/bin/sh
for i in $(find ./local_modules -type d -maxdepth 1) ; do
    packageJson="${i}/package.json"
    if [ -f "${packageJson}" ]; then
        echo "installing ${i}..."
        npm install "${i}"
    fi
done

The simplest supported solution is to either use margin

.element {
  display: block;
  margin: 0px auto;
}

Or use a second container around the element that has this margin applied. This will somewhat have the effect of padding: 0px auto if it did exist.

CSS

.element_wrapper {
  display: block;
  margin: 0px auto;
}
.element {
  background: blue;
}

HTML

<div class="element_wrapper">
  <div class="element">
    Hello world
  </div>
</div>

I've made a jQuery plugin for the equivalent of

<pre>
<?php echo print_r($data) ?>

Don't hardcode ip of containers in nginx config, docker link adds the hostname of the linked machine to the hosts file of the container and you should be able to ping by hostname.

EDIT: Docker 1.9 Networking no longer requires you to link containers, when multiple containers are connected to the same network, their hosts file will be updated so they can reach each other by hostname.

Every time a docker container spins up from an image (even stop/start-ing an existing container) the containers get new ip's assigned by the docker host. These ip's are not in the same subnet as your actual machines.

see docker linking docs (this is what compose uses in the background)

but more clearly explained in the docker-compose docs on links & expose

links

links:
 - db
 - db:database
 - redis

An entry with the alias' name will be created in /etc/hosts inside containers for this service, e.g:

172.17.2.186  db
172.17.2.186  database
172.17.2.187  redis

expose

Expose ports without publishing them to the host machine - they'll only be accessible to linked services. Only the internal port can be specified.

and if you set up your project to get the ports + other credentials through environment variables, links automatically set a bunch of system variables:

To see what environment variables are available to a service, run docker-compose run SERVICE env.

name_PORT

Full URL, e.g. DB_PORT=tcp://172.17.0.5:5432

name_PORT_num_protocol

Full URL, e.g. DB_PORT_5432_TCP=tcp://172.17.0.5:5432

name_PORT_num_protocol_ADDR

Container's IP address, e.g. DB_PORT_5432_TCP_ADDR=172.17.0.5

name_PORT_num_protocol_PORT

Exposed port number, e.g. DB_PORT_5432_TCP_PORT=5432

name_PORT_num_protocol_PROTO

Protocol (tcp or udp), e.g. DB_PORT_5432_TCP_PROTO=tcp

name_NAME

Fully qualified container name, e.g. DB_1_NAME=/myapp_web_1/myapp_db_1

If, like me, you would just prefer people didn't click out to youtube using the logo, one option is to use a player like jwplayer. Using jwplayer the logo is still there just unclickable.

For the first one: your program will go through the loop once for every row in the result set returned by the query. You can know in advance how many results there are by using mysql_num_rows().

For the second one: this time you are only using one row of the result set and you are doing something for each of the columns. That's what the foreach language construct does: it goes through the body of the loop for each entry in the array $row. The number of times the program will go through the loop is knowable in advance: it will go through once for every column in the result set (which presumably you know, but if you need to determine it you can use count($row)).

Tip for Windows users: Run this PowerShell command from within node_modules parent directory:

ls .\node_modules | % {npm uninstall $_}

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

If using Subdomains, for example like "pt.mydomain.com" to set portuguese for example, using Application_AcquireRequestState won't work, because it's not called on subsequent cache requests.

To solve this, I suggest an implementation like this:

1. Add the VaryByCustom parameter to the OutPutCache like this:

   [OutputCache(Duration = 10000, VaryByCustom = "lang")]
   public ActionResult Contact()
   {
       return View("Contact");
   }
   

2. In global.asax.cs, get the culture from the host using a function call:

   protected void Application_AcquireRequestState(object sender, EventArgs e)
   {
       System.Threading.Thread.CurrentThread.CurrentUICulture = GetCultureFromHost();
   }
   

3. Add the GetCultureFromHost function to global.asax.cs:

   private CultureInfo GetCultureFromHost()
   {
       CultureInfo ci = new CultureInfo("en-US"); // en-US
       string host = Request.Url.Host.ToLower();
       if (host.Equals("mydomain.com"))
       {
           ci = new CultureInfo("en-US");
       }
       else if (host.StartsWith("pt."))
       {
           ci = new CultureInfo("pt");
       }
       else if (host.StartsWith("de."))
       {
           ci = new CultureInfo("de");
       }
       else if (host.StartsWith("da."))
       {
           ci = new CultureInfo("da");
       }
   
       return ci;
   }
   

4. And finally override the GetVaryByCustomString(...) to also use this function:

   public override string GetVaryByCustomString(HttpContext context, string value)
   {
       if (value.ToLower() == "lang")
       {
           CultureInfo ci = GetCultureFromHost();
           return ci.Name;
       }
       return base.GetVaryByCustomString(context, value);
   }
   

The function Application_AcquireRequestState is called on non-cached calls, which allows the content to get generated and cached. GetVaryByCustomString is called on cached calls to check if the content is available in cache, and in this case we examine the incoming host domain value, again, instead of relying on just the current culture info, which could have changed for the new request (because we are using subdomains).

Input type text and oninput event with regex to accept only numbers worked for me.

<input type="text" maxlength="4" oninput="this.value=this.value.replace(/[^0-9]/g,'');" id="myId"/>

try{
    // ...
} catch (...) {
    // ...
}

will catch all C++ exceptions, but it should be considered bad design. You can use c++11's new current_exception mechanism, but if you don't have the ability to use c++11 (legacy code systems requiring a rewrite), then you have no named exception pointer to use to get a message or name. You may want to add separate catch clauses for the various exceptions you can catch, and only catch everything at the bottom to record an unexpected exception. E.g.:

try{
    // ...
} catch (const std::exception& ex) {
    // ...
} catch (const std::string& ex) {
    // ...
} catch (...) {
    // ...
}

When you think of unmanaged, think machine-specific, machine-level code. Like x86 assembly language. Unmanaged (native) code is compiled and linked to run directly on the processor it was designed for, excluding all the OS stuff for the moment. It's not portable, but it is fast. Very simple, stripped down code.

Managed code is everything from Java to old Interpretive BASIC, or anything that runs under .NET. Managed code typically is compiled to an intermediate level P-Code or byte code set of instructions. These are not machine-specific instructions, although they look similar to assembly language. Managed code insulates the program from the machine it's running on, and creates a secure boundary in which all memory is allocated indirectly, and generally speaking, you don't have direct access to machine resources like ports, memory address space, the stack, etc. The idea is to run in a more secure environment.

To convert from a managed variable, say, to an unmanaged one, you have to get to the actual object itself. It's probably wrapped or boxed in some additional packaging. UNmanaged variables (like an 'int', say) - on a 32 bit machine - takes exactly 4 bytes. There is no overhead or additional packaging. The process of going from managed to unmanaged code - and back again - is called "marshaling". It allows your programs to cross the boundary.

Here are modern mixins that I use (credits: PSA: don't use gradient generators):

.buttonAkc
{
    .gradientBackground(@imageName: 'accept.png');
    background-repeat: no-repeat !important;
    background-position: center right, top left !important;
}

.buttonAkc:hover
{
    .gradientBackgroundHover('accept.png');
}

.gradientBackground(@startColor: #fdfdfd, @endColor: #d9d9db, @imageName)
{
    background-color: mix(@startColor, @endColor, 60%); // fallback
    background-image: url("@{img-folder}/@{imageName}?v=@{version}"); // fallback
    background: url("@{img-folder}/@{imageName}?v=@{version}") no-repeat scroll right center, -webkit-linear-gradient(top, @startColor 0%, @endColor 100%) no-repeat scroll left top; // Chrome 10-25, Safari 5.1-6
    background: url("@{img-folder}/@{imageName}?v=@{version}") no-repeat scroll right center, linear-gradient(to bottom, @startColor 0%, @endColor 100%) no-repeat scroll left top;
}

.gradientBackgroundHover(@imageName)
{
    .gradientBackground(#fdfdfd, #b5b6b9, @imageName);
}

I was over-complicating myself. After taking a long break and coming back, the desired output could be accomplished by this simple query:

SELECT Sandwiches.[Sandwich Type], Sandwich.Bread, Count(Sandwiches.[SandwichID]) AS [Total Sandwiches]
FROM Sandwiches
GROUP BY Sandwiches.[Sandwiches Type], Sandwiches.Bread;

Thanks for answering, it helped my train of thought.

I hope this helps .. I got this same error message (Server not found in Kerberos database (7)) but this occurs after the successful use of the keytab to login.

The error message occurs when we attempt to use the credentials to do LDAP searches against AD.

This has only started happening since java 1.6.0_34 - it worked with 1.6.0_31 which I think was previous release. The error occurs because the java doesn't trust that the KDC it is communicating with for LDAP is actually part of the Kerberos realm. In our case, I think it is because the LDAP connection is made with the server name found via the round-robin'd resolved query. That is, java resolves realm.example.com, but gets any one of kdc1.example.com or kdc2.example .com ..etc). They must have tightened the checking betweeen these releases.

In our case the problem was worked around by setting the ldap server name directly rather than relying on DNS.

But investigations continue.

Make sure that your log4j is configured correctly, there's probably an exception that is being thrown, but you're only seeing half of the picture.

NOTE: I am sharing this. It is not mean that here is not good answer but because I easily understood.

Answer:

When a class is conceptualized, what are the properties we can have in it given the context. If we are designing a class Animal in the context of a zoo, it is important that we have an attribute as animalType to describe domestic or wild. This attribute may not make sense when we design the class in a different context.

Similarly, what are the behaviors we are going to have in the class? Abstraction is also applied here. What is necessary to have here and what will be an overdose? Then we cut off some information from the class. This process is applying abstraction.

When we ask for difference between encapsulation and abstraction, I would say, encapsulation uses abstraction as a concept. So then, is it only encapsulation. No, abstraction is even a concept applied as part of inheritance and polymorphism.

Go here for more explanation about this topic.

It worked perfectly for me in this way:

    RadioGroup radioGroup = (RadioGroup) findViewById(R.id.radio_group);
    int radioButtonID = radioGroup.getCheckedRadioButtonId();
    RadioButton radioButton = (RadioButton) radioGroup.findViewById(radioButtonID);
    String selectedtext = (String) radioButton.getText();

Use python-textops package :

from textops import *

'oldfile.txt' | cat() | grepv('bad') | tofile('newfile.txt')

I have just experienced the same problem. After some trial-and-error I discovered that if the selection was to the right of my filter area AND the number of shown records was zero, ShowAllData would fail.

A little more context is probably relevant. I have a number of sheets, each with a filter. I would like to set up some standard filters on all sheets, therefore I use some VBA like this

Sheets("Server").Select
col = Range("1:1").Find("In Selected SLA").Column
ActiveSheet.ListObjects("Srv").Range.AutoFilter Field:=col, Criteria1:="TRUE"

This code will adjust the filter on the column with heading "In Selected SLA", and leave all other filters unchanged. This has the unfortunate side effect that I can create a filter that shows zero records. This is not possible using the UI alone.

To avoid that situation, I would like to reset all filters before I apply the filtering above. My reset code looked like this

Sheets("Server").Select
If ActiveSheet.FilterMode Then ActiveSheet.ShowAllData

Note how I did not move the selected cell. If the selection was to the right, it would not remove filters, thus letting the filter code build a zero-row filter. The second time the code is run (on a zero-row filter) ShowAllData will fail.

The workaround is simple: Move the selection inside the filter columns before calling ShowAllData

Application.Goto (Sheets("Server").Range("A1"))
If ActiveSheet.FilterMode Then ActiveSheet.ShowAllData

This was on Excel version 14.0.7128.5000 (32-bit) = Office 2010

It could also mean something like "Lexical Environment Type or Tied".. It bothers me that it would simply be "let this be that". And let rec wouldn't make sense in lambda calculus.

You need to check both document.referrer and history.length like in my answer to similar question here: https://stackoverflow.com/a/36645802/1145274

In iOS this worked fine for me

CGFloat height = self.inputTableView.contentSize.height;
if (height > CGRectGetHeight(self.inputTableView.frame)) {
    height -= (CGRectGetHeight(self.inputTableView.frame) - CGRectGetHeight(self.navigationController.navigationBar.frame));
}
else {
    height = 0;
}
[self.inputTableView setContentOffset:CGPointMake(0, height) animated:animated];

It needs to be called from viewDidLayoutSubviews

Storm's answer is not correct. No hard feelings Storm, and apologies to the OP as I'm a bit late to the party here (wish I could have helped sooner, but I didn't run into the problem until today, or this stack overflow answer until I was figuring out a solution.)

The Visual C++ 2003 runtime was not available as a seperate download because it was included with the .NET 1.1 runtime.

If you install the .NET 1.1 runtime you will get msvcr71.dll installed, and in addition added to C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322.

The .NET 1.1 runtime is available here: http://www.microsoft.com/downloads/en/details.aspx?familyid=262d25e3-f589-4842-8157-034d1e7cf3a3&displaylang=en (23.1 MB)

If you are looking for a file that ends with a "P" such as msvcp71.dll, this indicates that your file was compiled against a C++ runtime (as opposed to a C runtime), in some situations I noticed these files were only installed when I installed the full SDK. If you need one of these files, you may need to install the full .NET 1.1 SDK as well, which is available here: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=9b3a2ca6-3647-4070-9f41-a333c6b9181d (106.2 MB)

After installing the SDK I now have both msvcr71.dll and msvcp71.dll in my System32 folder, and the application I'm trying to run (boomerang c++ decompiler) works fine without any missing DLL errors.

Also on a side note: be VERY aware of the difference between a Hotfix Update and a Regular Update. As noted in the linked KB932298 download (linked below by Storm): "Please be aware this Hotfix has not gone through full Microsoft product regression testing nor has it been tested in combination with other Hotfixes."

Hotfixes are NOT meant for general users, but rather users who are facing a very specific problem. As described in the article only install that Hotfix if you are have having specific daylight savings time issues with the rules that changed in 2007. -- Likely this was a pre-release for customers who "just couldn't wait" for the official update (probably for some business critical application) -- for regular users Windows Update should be all you need.

Thanks, and I hope this helps others who run into this issue!

Go for the full installation of Git for windows (with Unix tool), and bison and flex would come with it in the bin folder.

My problem was that POST requests need trailing slashes '/'.

If you are not into Cygwin, you can use native Windows builds. Some are here: curl Download Wizard.

For protobuf 2.5, use the dependency:

"com.googlecode.protobuf-java-format" % "protobuf-java-format" % "1.2"

Then use the code:

com.googlecode.protobuf.format.JsonFormat.merge(json, builder)
com.googlecode.protobuf.format.JsonFormat.printToString(proto)

you should use :

Upcasting is casting to a supertype, while downcasting is casting to a subtype. Upcasting is always allowed, but downcasting involves a type check and can throw a ClassCastException.

In your case, a cast from a Dog to an Animal is an upcast, because a Dog is-a Animal. In general, you can upcast whenever there is an is-a relationship between two classes.

Downcasting would be something like this:

Animal animal = new Dog();
Dog castedDog = (Dog) animal;

Basically what you're doing is telling the compiler that you know what the runtime type of the object really is. The compiler will allow the conversion, but will still insert a runtime sanity check to make sure that the conversion makes sense. In this case, the cast is possible because at runtime animal is actually a Dog even though the static type of animal is Animal.

However, if you were to do this:

Animal animal = new Animal();
Dog notADog = (Dog) animal;

You'd get a ClassCastException. The reason why is because animal's runtime type is Animal, and so when you tell the runtime to perform the cast it sees that animal isn't really a Dog and so throws a ClassCastException.

To call a superclass's method you can do super.method() or by performing the upcast.

To call a subclass's method you have to do a downcast. As shown above, you normally risk a ClassCastException by doing this; however, you can use the instanceof operator to check the runtime type of the object before performing the cast, which allows you to prevent ClassCastExceptions:

Animal animal = getAnimal(); // Maybe a Dog? Maybe a Cat? Maybe an Animal?
if (animal instanceof Dog) {
    // Guaranteed to succeed, barring classloader shenanigans
    Dog castedDog = (Dog) animal;
}

I figured that the DJANGO_SETTINGS_MODULE had to be set some way, so I looked at the documentation (link updated) and found:

export DJANGO_SETTINGS_MODULE=mysite.settings

Though that is not enough if you are running a server on heroku, you need to specify it there, too. Like this:

heroku config:set DJANGO_SETTINGS_MODULE=mysite.settings --account <your account name> 

In my specific case I ran these two and everything worked out:

export DJANGO_SETTINGS_MODULE=nirla.settings
heroku config:set DJANGO_SETTINGS_MODULE=nirla.settings --account personal

Edit

I would also like to point out that you have to re-do this every time you close or restart your virtual environment. Instead, you should automate the process by going to venv/bin/activate and adding the line: set DJANGO_SETTINGS_MODULE=mysite.settings to the bottom of the code. From now on every time you activate the virtual environment, you will be using that app's settings.

I am not sure how this happened but I started to get this error in my internal submit form pages. So when ever I submit something I'm getting this error. But the problem is this website is almost working 5-6 years. I don't remember I made an important change.

None of the solutions worked for me.

I have setup a machine key with the Microsoft script and copied into my web.config

I have executed asp.net regiis script.

aspnet_regiis -ga "IIS APPPOOL\My App Pool"

Also tried to add this code into the page:

enableViewStateMac="false"

still no luck.

Any other idea to solve this issue?

UPDATE:

Finally I solved the issue. I had integrated my angular 4 component into my asp.net website. So I had added base href into my master page. So I removed that code and it is working fine now.

<base href="/" />

This code creates a nice vertical scrollbar for me in Firefox and Chrome:

#answerform {
  position: absolute;
  border: 5px solid gray;
  padding: 5px;
  background: white;
  width: 300px;
  height: 400px;
  overflow-y: scroll;
}

<div id='answerform'>
  badger<br><br>badger<br><br>badger<br><br>badger<br><br>badger<br><br> mushroom
  <br><br>mushroom<br><br> a badger<br><br>badger<br><br>badger<br><br>badger<br><br>badger<br><br>
</div>

Here is a JS fiddle demo proving the above works.

I still prefer using dc, which is an RPN calculator, so quick session to divide 67 by 18 with 4 digits precision would look like

>dc
4k
67
18/p
3.7222
q
>

Obviously, much more available: man dc

I came across this solution from @jbabey while trying to solve a similar problem. With a little modification, I got it right. In my case, the object keys are numbers (489) and strings ("489"). Hence to solve this, each key is parse. The following code works:

var array = {"nR": 22, "nH": 7, "totB": "2761", "nSR": 16, "htRb": "91981"}
var parskey = 0;
for (var key in array) {
    parskey = parseInt(array[key]);
    sum += parskey;
};
return(sum);

Convert a number into a string, keeping only two decimals:

var num = 5.56789;
var n = num.toFixed(2);

The result of n will be:

5.57

With angular 6 spread operator and concat not work. You can resolve it easy:

result.push(...data);

Drag & Drop

To install apk in avd, just manually drag and drop the apk file in the opened emulated device

The same if you want to copy a file to the sd card

Try this:

SCRIPT:

function winOpen()
{
    window.open("yourpage.jsp");
}

HTML:

<a href="javascript:;" onclick="winOpen()">Pop Up</a>

Read https://developer.mozilla.org/en/docs/DOM/window.open for window.open

The 2018 ES6+ ANSWER IS:

    const arr = [1, 2, 3];

    arr.forEach((val, key, arr) => {
      if (Object.is(arr.length - 1, key)) {
        // execute last item logic
        console.log(`Last callback call at index ${key} with value ${val}` ); 
      }
    });

$("#birthday").change(function (){


var val=this.value;

var current_year=new Date().getFullYear();
if(val!=null){
    var Split = val.split("-");
    var birth_year=parseInt(Split[2]);

    if(parseInt(current_year)-parseInt(birth_year)<parseInt(18)){

  $("#maritial_status").attr('disabled', 'disabled');
        var val2= document.getElementById("maritial_status");
        val2.value = "Not Married";
        $("#anniversary").attr('disabled', 'disabled');
        var val1= document.getElementById("anniversary");
        val1.value = "NA";

    }else{
        $("#maritial_status").attr('disabled', false);
        $("#anniversary").attr('disabled', false);

    }
}
});

The following code snippet helps you to create a complete path.

Function GenerateFolder($path) {
    $global:foldPath = $null
    foreach($foldername in $path.split("\")) {
        $global:foldPath += ($foldername+"\")
        if (!(Test-Path $global:foldPath)){
            New-Item -ItemType Directory -Path $global:foldPath
            # Write-Host "$global:foldPath Folder Created Successfully"
        }
    }
}

The above function split the path you passed to the function and will check each folder whether it exists or not. If it does not exist it will create the respective folder until the target/final folder created.

To call the function, use below statement:

GenerateFolder "H:\Desktop\Nithesh\SrcFolder"

Basically, with prepared statements the data coming in from a potential hacker is treated as data - and there's no way it can be intermixed with your application SQL and/or be interpreted as SQL (which can happen when data passed in is placed directly into your application SQL).

This is because prepared statements "prepare" the SQL query first to find an efficient query plan, and send the actual values that presumably come in from a form later - at that time the query is actually executed.

More great info here:

Prepared statements and SQL Injection

API level is basically the Android version. Instead of using the Android version name (eg 2.0, 2.3, 3.0, etc) an integer number is used. This number is increased with each version. Android 1.6 is API Level 4, Android 2.0 is API Level 5, Android 2.0.1 is API Level 6, and so on.

This should work...

var displayDate = new Date().toLocaleDateString();

alert(displayDate);

But I suspect you are trying it on something else, for example:

var displayDate = Date.now.toLocaleDateString(); // No!

alert(displayDate);

One way is to use NVM, the Node Version Manager.

Use following command to get nvm

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash

You can find it at https://github.com/creationix/nvm

It allows you to easily install and manage multiple versions of node. Here's a snippet from the help:

Usage:
nvm install <version>       Download and install a <version>
nvm use <version>           Modify PATH to use <version>
nvm ls                      List versions (installed versions are blue)

The answers didn't work for me with postgresql 9.1+

This is what I had to do (you can check more in the manual here)

UPDATE schema.TableA as A
SET "columnA" = "B"."columnB"
FROM schema.TableB as B
WHERE A.id = B.id;

You can omit the schema, if you are using the default schema for both tables.

I think there are different ways to do this. Since im not familiar with asp i can only give you some hints to check for a specific filetype:

1) the safe way: get more informations about the header of the filetype you wish to pass. parse the uploaded file and compare the headers

2) the quick way: split the name of the file into two pieces -> name of the file and the ending of the file. check out the ending of the file and compare it to the filetype you want to allow to be uploaded

hope it helps :)

You can also try Word Extractor tool. Word Extractor can be used with any file in your computer to separate the strings that contain human text / words from binary code (exe applications, DLLs).

Start > Computer : Properties > Change Settings > Advanced > Environment Variables > PATH : Edit [add this string (without "") at the end of line ";C:\<path to php folder>\php5.5.3"].. open cmd and type composer thats it :-)

You can do this

textView.text = "Name: \(string1) \n" + "Phone Number: \(string2)"

The output will be

Name: output of string1 Phone Number: output of string2

Class Parent cannot be declared because it is PHP reserved keyword so in effect it's already in use

I know this isn't exactly one command, but the desired result can be achieved from within phpMyAdmin by following these steps:

1. Select (all) tables to be removed (Check All)
2. Select "Drop" / "Truncate" from the "With selected:" list
3. On the confirmation page ("Do you really want to:") copy the query (everything with the red background)
4. Go at the top and click on SQL and write: "SET FOREIGN_KEY_CHECKS=0;" then paste the previously copied query
5. Click "Go"

The idea is to quickly get all the tables from the database (which you do in 5 seconds and 2 clicks) but disable foreign key checks first. No CLI and no dropping the database and adding it again.

Just press windows button and type %APPDATA% and type enter.

Above is the location where you can find \npm\node_modules folder. This is where global modules sit in your system.

The standard tool for listing symbols is nm, you can use it simply like this:

nm -gD yourLib.so

If you want to see symbols of a C++ library, add the "-C" option which demangle the symbols (it's far more readable demangled).

nm -gDC yourLib.so

If your .so file is in elf format, you have two options:

Either objdump (-C is also useful for demangling C++):

$ objdump -TC libz.so

libz.so:     file format elf64-x86-64

You can use cin.get(); or cin.ignore(); just before your return statement to avoid the console window from closing.

There are 2 possibilities. In either case PyGame has to be initialized by pygame.init.

import pygame
pygame.init()

Use either the pygame.font module and create a pygame.font.SysFont or pygame.font.Font object. render() a pygame.Surface with the text and blit the Surface to the screen:

my_font = pygame.font.SysFont(None, 50)
text_surface = myfont.render("Hello world!", True, (255, 0, 0))
screen.blit(text_surface, (10, 10))

Or use the pygame.freetype module. Create a pygame.freetype.SysFont() or pygame.freetype.Font object. render() a pygame.Surface with the text or directly render_to() the text to the screen:

my_ft_font = pygame.freetype.SysFont('Times New Roman', 50)
my_ft_font.render_to(screen, (10, 10), "Hello world!", (255, 0, 0))

Choose one of the options- OPTION A

1. Delete the 'local.properties' file in 'Gradle Script'
2. Create new 'local.properties' file there
3. Paste this into your new 'local.properties' file sdk.dir=/Users/uttam/Library/Android/sdk

OPTION B

1. copy the 'local.properties' file from your any old project.
2. paste this in your new project, you will be asked confirmation, choose 'replace'

For Googlers, another way to get a list of users is to use:

Get-WmiObject -Class Win32_UserAccount

You can set proxies using environment variables.

import os
os.environ['http_proxy'] = '127.0.0.1'
os.environ['https_proxy'] = '127.0.0.1'

urllib2 will add proxy handlers automatically this way. You need to set proxies for different protocols separately otherwise they will fail (in terms of not going through proxy), see below.

For example:

proxy = urllib2.ProxyHandler({'http': '127.0.0.1'})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)
urllib2.urlopen('http://www.google.com')
# next line will fail (will not go through the proxy) (https)
urllib2.urlopen('https://www.google.com')

Instead

proxy = urllib2.ProxyHandler({
    'http': '127.0.0.1',
    'https': '127.0.0.1'
})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)
# this way both http and https requests go through the proxy
urllib2.urlopen('http://www.google.com')
urllib2.urlopen('https://www.google.com')

As I felt similarly confused with .transform operation vs. .apply I found a few answers shedding some light on the issue. This answer for example was very helpful.

My takeout so far is that .transform will work (or deal) with Series (columns) in isolation from each other. What this means is that in your last two calls:

df.groupby('A').transform(lambda x: (x['C'] - x['D']))
df.groupby('A').transform(lambda x: (x['C'] - x['D']).mean())

You asked .transform to take values from two columns and 'it' actually does not 'see' both of them at the same time (so to speak). transform will look at the dataframe columns one by one and return back a series (or group of series) 'made' of scalars which are repeated len(input_column) times.

So this scalar, that should be used by .transform to make the Series is a result of some reduction function applied on an input Series (and only on ONE series/column at a time).

Consider this example (on your dataframe):

zscore = lambda x: (x - x.mean()) / x.std() # Note that it does not reference anything outside of 'x' and for transform 'x' is one column.
df.groupby('A').transform(zscore)

will yield:

       C      D
0  0.989  0.128
1 -0.478  0.489
2  0.889 -0.589
3 -0.671 -1.150
4  0.034 -0.285
5  1.149  0.662
6 -1.404 -0.907
7 -0.509  1.653

Which is exactly the same as if you would use it on only on one column at a time:

df.groupby('A')['C'].transform(zscore)

yielding:

0    0.989
1   -0.478
2    0.889
3   -0.671
4    0.034
5    1.149
6   -1.404
7   -0.509

Note that .apply in the last example (df.groupby('A')['C'].apply(zscore)) would work in exactly the same way, but it would fail if you tried using it on a dataframe:

df.groupby('A').apply(zscore)

gives error:

ValueError: operands could not be broadcast together with shapes (6,) (2,)

So where else is .transform useful? The simplest case is trying to assign results of reduction function back to original dataframe.

df['sum_C'] = df.groupby('A')['C'].transform(sum)
df.sort('A') # to clearly see the scalar ('sum') applies to the whole column of the group

yielding:

     A      B      C      D  sum_C
1  bar    one  1.998  0.593  3.973
3  bar  three  1.287 -0.639  3.973
5  bar    two  0.687 -1.027  3.973
4  foo    two  0.205  1.274  4.373
2  foo    two  0.128  0.924  4.373
6  foo    one  2.113 -0.516  4.373
7  foo  three  0.657 -1.179  4.373
0  foo    one  1.270  0.201  4.373

Trying the same with .apply would give NaNs in sum_C. Because .apply would return a reduced Series, which it does not know how to broadcast back:

df.groupby('A')['C'].apply(sum)

giving:

A
bar    3.973
foo    4.373

There are also cases when .transform is used to filter the data:

df[df.groupby(['B'])['D'].transform(sum) < -1]

     A      B      C      D
3  bar  three  1.287 -0.639
7  foo  three  0.657 -1.179

I hope this adds a bit more clarity.

To build on pinusnegra's answer, and in response to Gumbo's comment on that answer:

function has_leading_underscore($string) {

    return $string[0] === '_';

}

Running on PHP 5.3.0, the following works and returns the expected value, even without checking if the string is at least 1 character in length:

echo has_leading_underscore('_somestring').', ';
echo has_leading_underscore('somestring').', ';
echo has_leading_underscore('').', ';
echo has_leading_underscore(null).', ';
echo has_leading_underscore(false).', ';
echo has_leading_underscore(0).', ';
echo has_leading_underscore(array('_foo', 'bar'));

/*
 * output: true, false, false, false, false, false, false
 */

I don't know how other versions of PHP will react, but if they all work, then this method is probably more efficient than the substr route.

Okay This may sound Dumb but it worked for me.

as a total beginner, I didn't realized that writing:

router.post("/", (res, req) => {
  console.log(req.body);
  req.send("User Route");
});

is wrong !

You have make sure that you pass parameters(req,res) of post/get in right order: and call them accordingly:

router.post("/", (req, res) => {
  console.log(req.body);
  res.send("User Route");
});

If you're a minimalist like me. Say you only want to render a record with a list containing entries.

<div>
  {data.map((record) => (
    record.list.length > 0
      ? (<YourRenderComponent record={record} key={record.id} />)
      : null
  ))}
</div>

I was able to solve this problem by replacing the following:

In the Toolbar layout, replace everything which is like this:

android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"

with

android:minHeight="@dimen/abc_action_bar_default_height_material"
android:background="@color/myColor"

This happened to me, and it was caused the absence of a comment (should say "comment required" instead of this enigmatic error at first, right...)

I always use this, works perfect.

$(document).ready(function(){
        $(function(){
        $('#ideal_form').submit(function(e){
                e.preventDefault();
                var form = $(this);
                var post_url = form.attr('action');
                var post_data = form.serialize();
                $('#loader3', form).html('<img src="../../images/ajax-loader.gif" />       Please wait...');
                $.ajax({
                    type: 'POST',
                    url: post_url, 
                    data: post_data,
                    success: function(msg) {
                        $(form).fadeOut(800, function(){
                            form.html(msg).fadeIn().delay(2000);

                        });
                    }
                });
            });
        });
         });

You need to include a declaration of the printf() function.

#include <stdio.h>

There is better solution for Oracle instead of using dbms_random.value, while it requires full scan to order rows by dbms_random.value and it is quite slow for large tables.

Use this instead:

SELECT *
FROM employee sample(1)
WHERE rownum=1

I agree as well, using a timer is the best option. I have tried a solution similar to yours in the past and started having issues where the loop would misfire, and I would have to wait for another Thread.Sleep() before it would fire again. Also, it did cause all sorts of issues with stopping the service, I would get constant errors about how it wasn't responding and had to be closed.

@Prashanth's code should be exactly what you need.

Set decoding to true

Your decoding is not set to true. If you don't have access to set the source to true. The code below will fix it for you.

$WorkingArray = json_decode(json_encode($data),true);

You can't access a MySQL DB from Android natively. EDIT: Actually you may be able to use JDBC, but it is not recommended (or may not work?) ... see Android JDBC not working: ClassNotFoundException on driver

See

http://www.helloandroid.com/tutorials/connecting-mysql-database

http://www.basic4ppc.com/forum/basic4android-getting-started-tutorials/8339-connect-android-mysql-database-tutorial.html

Android cannot connect directly to the database server. Therefore we need to create a simple web service that will pass the requests to the database and will return the response.

For most [good] users this might be fine. But imagine you get a hacker that gets a hold of your program. I've decompiled my own applications and its scary what I've seen. What if they get your username / password to your database and wreak havoc? Bad.
