For me, the problem was having nested EAGER fetches.

One solution is to set the nested fields to LAZY and use Hibernate.initialize() to load the nested field(s):

x = session.get(ClassName.class, id);
Hibernate.initialize(x.getNestedField());

Use the ampersand & to glue variables together:

$url = "http://localhost/main.php?email=$email_address&event_id=$event_id";
//                               ^ start of vars      ^next var

I have a simpler solution. In your destination page (irc_online.php) add an auto-refresh tag in the header.

We could look at error object for a property code that mentions the possible system error and in cases of ETIMEDOUT where a network call fails, act accordingly.

if (err.code === 'ETIMEDOUT') {
    console.log('My dish error: ', util.inspect(err, { showHidden: true, depth: 2 }));
}

Using jQuery it is very simple assuming the URL you wish to post to is on the same server or has implemented CORS

$(function() {
  $("#employeeLink").on("click",function(e) {
    e.preventDefault(); // cancel the link itself
    $.post(this.href,function(data) {
      $("#someContainer").html(data);
    });
  });
});

If you insist on using frames which I strongly discourage, have a form and submit it with the link

<form action="employee.action" method="post" target="myFrame" id="myForm"></form>

and use (in plain JS)

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the link
     document.getElementById("myForm").submit(); // but make sure nothing has name or ID="submit"
   });
 });

Without a form we need to make one

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the actual link
     var myForm = document.createElement("form");
     myForm.action=this.href;// the href of the link
     myForm.target="myFrame";
     myForm.method="POST";
     myForm.submit();
   });
 });

In PHP 5 there is a new Object Model. PHP's handling of objects has been completely rewritten, allowing for better performance and more features. In previous versions of PHP, objects were handled like primitive types (for instance integers and strings). The drawback of this method was that semantically the whole object was copied when a variable was assigned, or passed as a parameter to a method. In the new approach, objects are referenced by handle, and not by value (one can think of a handle as an object's identifier).

Desired capabilities comes in handy while doing remote or parallel execution using selenium grid. We will be parametrizing the browser details and passing in to selenium server using desired capabilities class.

Another usage is, test automation using Appium as shown below

// Created object of DesiredCapabilities class. 
DesiredCapabilities capabilities = new DesiredCapabilities(); 
// Set android deviceName desired capability. Set your device name. 
capabilities.setCapability("deviceName", "your Device Name"); 
// Set BROWSER_NAME desired capability. 
capabilities.setCapability(CapabilityType.BROWSER_NAME, "Chrome"); 
// Set android VERSION desired capability. Set your mobile device's OS version. 
capabilities.setCapability(CapabilityType.VERSION, "5.1"); 
// Set android platformName desired capability. It's Android in our case here. 
capabilities.setCapability("platformName", "Android"); 

What worked for me is the following: I had a blank Variables view for the top stack frame. I selected a lower stack frame, then reselected the top one, and the Variables view refreshed itself somehow. Note: I'm using Eclipse Mars, so this bug appears to have returned in this version (or perhaps it's a different one, with the same symptoms?).

I know this question is old but in case if anyone will look for it in the future. It is possible to have two captcha's on one page. Pink to documentation is here: https://developers.google.com/recaptcha/docs/display Example below is just a copy form doc and you dont have to specify different layouts.

<script type="text/javascript">
  var verifyCallback = function(response) {
    alert(response);
  };
  var widgetId1;
  var widgetId2;
  var onloadCallback = function() {
    // Renders the HTML element with id 'example1' as a reCAPTCHA widget.
    // The id of the reCAPTCHA widget is assigned to 'widgetId1'.
    widgetId1 = grecaptcha.render('example1', {
      'sitekey' : 'your_site_key',
      'theme' : 'light'
    });
    widgetId2 = grecaptcha.render(document.getElementById('example2'), {
      'sitekey' : 'your_site_key'
    });
    grecaptcha.render('example3', {
      'sitekey' : 'your_site_key',
      'callback' : verifyCallback,
      'theme' : 'dark'
    });
  };
</script>

Try echo_read_request_body.

"echo_read_request_body ... Explicitly reads request body so that the $request_body variable will always have non-empty values (unless the body is so big that it has been saved by Nginx to a local temporary file)."

location /log {
  log_format postdata $request_body;
  access_log /mnt/logs/nginx/my_tracking.access.log postdata;
  echo_read_request_body;
}

You typically have to do this in a single syscall, or else you will get a race condition.

This will open for reading and writing, creating the file if necessary.

FILE *fp = fopen("scores.dat", "ab+");

If you want to read it and then write a new version from scratch, then do it as two steps.

FILE *fp = fopen("scores.dat", "rb");
if (fp) {
    read_scores(fp);
}

// Later...

// truncates the file
FILE *fp = fopen("scores.dat", "wb");
if (!fp)
    error();
write_scores(fp);

If you can use some dynamic query, you can use LEN . It will give false on both empty and null string. By this way you can implement the option parameter.

ALTER PROCEDURE [dbo].[psProducts] 
(@SearchType varchar(50))
AS
BEGIN
    SET NOCOUNT ON;

DECLARE @Query nvarchar(max) = N'
    SELECT 
        P.[ProductId],
        P.[ProductName],
        P.[ProductPrice],
        P.[Type]
    FROM [Product] P'
    -- if @Searchtype is not null then use the where clause
    SET @Query = CASE WHEN LEN(@SearchType) > 0 THEN @Query + ' WHERE p.[Type] = ' + ''''+ @SearchType + '''' ELSE @Query END   

    EXECUTE sp_executesql @Query
    PRINT @Query
END

An .xsd file is called an XML schema. Via an XML schema, we may require a certain structure in a given XML - which elements in which order, how many times, with which attributes, how they are nested, etc. If we have a schema for our XML input, we can verify that it contains the data we need it to contain, and nothing else, with a few lines invoking a schema validator.

I got the same issue with quaternion module. When updating modules with conda, the numpy version is not up^dated to the last one. If forcing update with pip command pip install --upgrade numpy + install quaternion module by pip install --user numpy numpy-quaternion, the issue is fixed. May be the issue is coming from the numpy version. Here the execution result:

I see this question so much! everywhere I look lacks the real answer.

The php.ini should be in the wp-admin directory, if it isn't just create it and then define whats needed, by default it should contain.

upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300

You're looking for the wrong selector id:

 $("#submitter").text(submitter_name);

should be

 $("#submittername").text(submitter_name);

For Windows using ZBar

Pre-requisites:

• Install ZBar by either:
  • Install Chocolatey and choco install zbar
  • Or use Windows Installer for ZBar
• pip install pyzbar

To decode:

from PIL import Image
from pyzbar import pyzbar

img = Image.open('My-Image.jpg')
output = pyzbar.decode(img)
print(output)

Alternatively, you can also try using ZBarLight by setting it up as mentioned here:
https://pypi.org/project/zbarlight/

First, please do not use extract(), it can be a security problem because it is easy to manipulate POST parameters

In addition, you don't have to use variable variable names (that sounds odd), instead:

foreach($_POST as $key => $value) {
  echo "POST parameter '$key' has '$value'";
}

To ensure that you have only parameters beginning with 'item_name' you can check it like so:

$param_name = 'item_name';
if(substr($key, 0, strlen($param_name)) == $param_name) {
  // do something
}

In my case I needed to install "JST Server Adapters". I am running Eclipse 3.6 Helios RCP Edition.

Here are the steps I followed:

1. Help -> Install New Software
2. Choose "Helios - http://download.eclipse.org/releases/helios" site or kepler - http://download.ecliplse.org/releases/kepler
3. Expand "Web, XML, and Java EE Development"
4. Check JST Server Adapters (version 3.2.2)

After that I could define new Server Runtime Environments.

EDIT: With Eclipse 3.7 Indigo Classic, Eclipse Kepler and Luna, the steps are the same (with appropriate update site) but you need both JST Server Adapters and JST Server Adapters Extentions to get the Server Runtime Environment options.

The short answer to this question is that none of these values are a reliable indicator of how much memory an executable is actually using, and none of them are really appropriate for debugging a memory leak.

Private Bytes refer to the amount of memory that the process executable has asked for - not necessarily the amount it is actually using. They are "private" because they (usually) exclude memory-mapped files (i.e. shared DLLs). But - here's the catch - they don't necessarily exclude memory allocated by those files. There is no way to tell whether a change in private bytes was due to the executable itself, or due to a linked library. Private bytes are also not exclusively physical memory; they can be paged to disk or in the standby page list (i.e. no longer in use, but not paged yet either).

Working Set refers to the total physical memory (RAM) used by the process. However, unlike private bytes, this also includes memory-mapped files and various other resources, so it's an even less accurate measurement than the private bytes. This is the same value that gets reported in Task Manager's "Mem Usage" and has been the source of endless amounts of confusion in recent years. Memory in the Working Set is "physical" in the sense that it can be addressed without a page fault; however, the standby page list is also still physically in memory but not reported in the Working Set, and this is why you might see the "Mem Usage" suddenly drop when you minimize an application.

Virtual Bytes are the total virtual address space occupied by the entire process. This is like the working set, in the sense that it includes memory-mapped files (shared DLLs), but it also includes data in the standby list and data that has already been paged out and is sitting in a pagefile on disk somewhere. The total virtual bytes used by every process on a system under heavy load will add up to significantly more memory than the machine actually has.

So the relationships are:

• Private Bytes are what your app has actually allocated, but include pagefile usage;
• Working Set is the non-paged Private Bytes plus memory-mapped files;
• Virtual Bytes are the Working Set plus paged Private Bytes and standby list.

There's another problem here; just as shared libraries can allocate memory inside your application module, leading to potential false positives reported in your app's Private Bytes, your application may also end up allocating memory inside the shared modules, leading to false negatives. That means it's actually possible for your application to have a memory leak that never manifests itself in the Private Bytes at all. Unlikely, but possible.

Private Bytes are a reasonable approximation of the amount of memory your executable is using and can be used to help narrow down a list of potential candidates for a memory leak; if you see the number growing and growing constantly and endlessly, you would want to check that process for a leak. This cannot, however, prove that there is or is not a leak.

One of the most effective tools for detecting/correcting memory leaks in Windows is actually Visual Studio (link goes to page on using VS for memory leaks, not the product page). Rational Purify is another possibility. Microsoft also has a more general best practices document on this subject. There are more tools listed in this previous question.

I hope this clears a few things up! Tracking down memory leaks is one of the most difficult things to do in debugging. Good luck.

• \s matches any white-space character
• \S matches any non-white-space character
• You can match a space character with just the space character;
• [^ ] matches anything but a space character.

Pick whichever is most appropriate.

ESLint supports this as of version >= 4:

/*
.eslintrc.js
*/
const ERROR = 2;
const WARN = 1;

module.exports = {
  extends: "eslint:recommended",
  env: {
    es6: true
  },
  overrides: [
    {
      files: [
        "**/*.test.js"
      ],
      env: {
        jest: true // now **/*.test.js files' env has both es6 *and* jest
      },
      // Can't extend in overrides: https://github.com/eslint/eslint/issues/8813
      // "extends": ["plugin:jest/recommended"]
      plugins: ["jest"],
      rules: {
        "jest/no-disabled-tests": "warn",
        "jest/no-focused-tests": "error",
        "jest/no-identical-title": "error",
        "jest/prefer-to-have-length": "warn",
        "jest/valid-expect": "error"
      }
    }
  ],
};

Here is a workaround (from another answer on here, vote it up!) for the "extend in overrides" limitation of eslint config :

overrides: [
  Object.assign(
    {
      files: [ '**/*.test.js' ],
      env: { jest: true },
      plugins: [ 'jest' ],
    },
    require('eslint-plugin-jest').configs.recommended
  )
]

This probably has the same table to other schema the reason why you're getting that error.

You need to drop first the child row then the parent row.

You are right. This is a badly documented issue. But you can change the font size parameter (by opposition to font scale) directly after building the plot. Check the following example:

import seaborn as sns
tips = sns.load_dataset("tips")

b = sns.boxplot(x=tips["total_bill"])
b.axes.set_title("Title",fontsize=50)
b.set_xlabel("X Label",fontsize=30)
b.set_ylabel("Y Label",fontsize=20)
b.tick_params(labelsize=5)
sns.plt.show()

, which results in this:

To make it consistent in between plots I think you just need to make sure the DPI is the same. By the way it' also a possibility to customize a bit the rc dictionaries since "font.size" parameter exists but I'm not too sure how to do that.

NOTE: And also I don't really understand why they changed the name of the font size variables for axis labels and ticks. Seems a bit un-intuitive.

How about using Request — Simplified HTTP client.

Edit February 2020: Request has been deprecated so you probably shouldn't use it any more.

Here's a GET:

var request = require('request');
request('http://www.google.com', function (error, response, body) {
    if (!error && response.statusCode == 200) {
        console.log(body) // Print the google web page.
     }
})

OP also wanted a POST:

request.post('http://service.com/upload', {form:{key:'value'}})

I am using a powershell build and couldn't get npm to run without changing the current directory.

Ended up using the start command and just specifying the working directory:

start "npm" -ArgumentList "install --warn" -wo $buildFolder

This method uses the 'C' memset function, and is very fast (avoids a char-by-char loop).

const uint size = 65546;
char* msg = new char[size];
memset(reinterpret_cast<void*>(msg), 0, size);

I usually use the following techinque to run the same app as a console application or as a service:

public static class Program
{
    #region Nested classes to support running as service
    public const string ServiceName = "MyService";

    public class Service : ServiceBase
    {
        public Service()
        {
            ServiceName = Program.ServiceName;
        }

        protected override void OnStart(string[] args)
        {
            Program.Start(args);
        }

        protected override void OnStop()
        {
            Program.Stop();
        }
    }
    #endregion

    static void Main(string[] args)
    {
        if (!Environment.UserInteractive)
            // running as service
            using (var service = new Service())
                ServiceBase.Run(service);
        else
        {
            // running as console app
            Start(args);

            Console.WriteLine("Press any key to stop...");
            Console.ReadKey(true);

            Stop();
        }
    }

    private static void Start(string[] args)
    {
        // onstart code here
    }

    private static void Stop()
    {
        // onstop code here
    }
}

Environment.UserInteractive is normally true for console app and false for a service. Techically, it is possible to run a service in user-interactive mode, so you could check a command-line switch instead.

OK, there is more to it than that, you need zlib. zlib is part of CentOS, but you need the development form to get zlib.h ... notice that the yum name of zlib development is quite different possibly than for apt-get on ubuntu/debian, what follows actually works with my CentOS version
in particular, you do ./configure on git, then try make, and the first build fails with missing zlib.h

I used a two-step procedure to resolve this a) Got RPMFORGE for my version of CentOS

See: www.centos.org/modules/newbb/viewtopic.php?topic_id=18506&forum=38 and this: wiki.centos.org/AdditionalResources/Repositories/RPMForge

In my case [as root, or with sudo]

$ wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm
$ rpm -K rpmforge-release-0.5.2-2.el5.rf.*.rpm
$ rpm -i rpmforge-release-0.5.2-2.el5.rf.*.rpm
## Note: the RPM for rpmforge is small (like 12.3K) but don't let that fool
## you; it augments yum the next time you use yum
## [this is the name that YUM found] (still root or sudo)
$ yum install zlib-devel.x86_64
## and finally in the source directory for git (still root or sudo):
$ ./configure (this worked before, but I ran it again to be sure)
$ make
$ make install

(this install put it by default in /usr/local/bin/git ... not my favorite choice, but OK for the default)... and git works fine!

just copy " _CRT_SECURE_NO_WARNINGS " paste it on projects->properties->c/c++->preprocessor->preprocessor definitions click ok.it will work

Comparision:

if (userProfile.AccountType == AccountType.Retailer)
{
    //your code
}

In case to prevent the NullPointerException you could add the following condition before comparing the AccountType:

if(userProfile != null)
{
    if (userProfile.AccountType == AccountType.Retailer)
    {
       //your code
    }
}

or shorter version:

if (userProfile !=null && userProfile.AccountType == AccountType.Retailer)
{
    //your code
}

Probably because of optimizations. Excel 2007 can have a maximum of 16 384 columns and 1 048 576 rows. Strange numbers?

14 bits = 16 384, 20 bits = 1 048 576

14 + 20 = 34 bits = more than one 32 bit register can hold.

But they also need to store the format of the cell (text, number etc) and formatting (colors, borders etc). Assuming they use two 32-bit words (64 bit) they use 34 bits for the cell number and have 30 bits for other things.

Why is that important? In memory they don't need to allocate all the memory needed for the whole spreadsheet but only the memory necessary for your data, and every data is tagged with in what cell it is supposed to be in.

Update 2016:

Found a link to Microsoft's specification for Excel 2013 & 2016

• Open workbooks: Limited by available memory and system resources
• Worksheet size: 1,048,576 rows (20 bits) by 16,384 columns (14 bits)
• Column width: 255 characters (8 bits)
• Row height: 409 points
• Page breaks: 1,026 horizontal and vertical (unexpected number, probably wrong, 10 bits is 1024)
• Total number of characters that a cell can contain: 32,767 characters (signed 16 bits)
• Characters in a header or footer: 255 (8 bits)
• Sheets in a workbook: Limited by available memory (default is 1 sheet)
• Colors in a workbook: 16 million colors (32 bit with full access to 24 bit color spectrum)
• Named views in a workbook: Limited by available memory
• Unique cell formats/cell styles: 64,000 (16 bits = 65536)
• Fill styles: 256 (8 bits)
• Line weight and styles: 256 (8 bits)
• Unique font types: 1,024 (10 bits) global fonts available for use; 512 per workbook
• Number formats in a workbook: Between 200 and 250, depending on the language version of Excel that you have installed
• Names in a workbook: Limited by available memory
• Windows in a workbook: Limited by available memory
• Hyperlinks in a worksheet: 66,530 hyperlinks (unexpected number, probably wrong. 16 bits = 65536)
• Panes in a window: 4
• Linked sheets: Limited by available memory

This will work fast:

Case 1 - File2 = File1 + extra text appended.

grep -Fxvf File2.txt File1.txt >> File3.txt

File 1: 80 Lines File 2: 100 Lines File 3: 20 Lines

This has nothing to do with a malformed upload. The HTTP error clearly specifies 401 unauthorized, and tells you the CSRF token is invalid. Try sending a valid CSRF token with the upload.

From the composer site (it's clear enough)

require#

Lists packages required by this package. The package will not be installed unless those requirements can be met.

require-dev (root-only)#

Lists packages required for developing this package, or running tests, etc. The dev requirements of the root package are installed by default. Both install or update support the --no-dev option that prevents dev dependencies from being installed.

Using require-dev in Composer you can declare the dependencies you need for development/testing the project but don't need in production. When you upload the project to your production server (using git) require-dev part would be ignored.

Also check this answer posted by the author and this post as well.

As others have said, you can install a password cache helper. I mostly just wanted to post the link for other platforms, and not just Mac. I'm running a Linux server and this was helpful: Caching your GitHub password in Git

For Mac:

git credential-osxkeychain

Windows:

git config --global credential.helper wincred

Linux:

git config --global credential.helper cache
git config --global credential.helper 'cache --timeout=3600'
# Set the cache to timeout after 1 hour (setting is in seconds)

Answer by Adamski is a good one and describes the steps in an encoding operation when using the general encode method (that takes a byte buffer as one of the inputs)

However, the method in question (in this discussion) is a variant of encode - encode(CharBuffer in). This is a convenience method that implements the entire encoding operation. (Please see java docs reference in P.S.)

As per the docs, This method should therefore not be invoked if an encoding operation is already in progress (which is what is happening in ZenBlender's code -- using static encoder/decoder in a multi threaded environment).

Personally, I like to use convenience methods (over the more general encode/decode methods) as they take away the burden by performing all the steps under the covers.

ZenBlender and Adamski have already suggested multiple ways options to safely do this in their comments. Listing them all here:

• Create a new encoder/decoder object when needed for each operation (not efficient as it could lead to a large number of objects). OR,
• Use a ThreadLocal to avoid creating new encoder/decoder for each operation. OR,
• Synchronize the entire encoding/decoding operation (this might not be preferred unless sacrificing some concurrency is ok for your program)

P.S.

java docs references:

1. Encode (convenience) method: http://docs.oracle.com/javase/6/docs/api/java/nio/charset/CharsetEncoder.html#encode%28java.nio.CharBuffer%29
2. General encode method: http://docs.oracle.com/javase/6/docs/api/java/nio/charset/CharsetEncoder.html#encode%28java.nio.CharBuffer,%20java.nio.ByteBuffer,%20boolean%29

As said @v.ladynev, it works with JDK 1.7

With Eclipse, to be able to perform a "Run As" maven install with the TLS command-line parameter, just configure the JDK you're using.

Open the dialog through Window > Preferences > Java > Installed JREs.

Then highlight the one you're using (should be a JDK, not a JRE), click on Edit. In the field "Default VM arguments", fill the value -Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2. As shown below:

Clean the project (maybe optional), then re-run a maven install.

navigate to the url http://jmeter.apache.org/download_jmeter.cgi-->download apache-jmeter-2.11.zip, which is under binaries.

this error is occurring since Apache jmeter.jar is missing in bin folder

1) Check sysctl file-max limit:

$ cat /proc/sys/fs/file-max

If the limit is lower than your desired value, open the sysctl.conf and add this line at the end of file:

fs.file-max = 65536

Finally, apply sysctl limits:

$ sysctl -p 

2) Edit /etc/security/limits.conf and add below the mentioned

* soft     nproc          65535    
* hard     nproc          65535   
* soft     nofile         65535   
* hard     nofile         65535

These limits won't apply for root user, if you want to change root limits you have to do that explicitly:

root soft     nofile         65535   
root hard     nofile         65535
...

3) Reboot system or add following line to the end of /etc/pam.d/common-session:

session required pam_limits.so

Logout and login again.

4) Check soft limits:

$ ulimit -a

and hard limits:

$ ulimit -Ha
....

open files                      (-n) 65535

There is no native method in Java to do that for you. However, you can use IterableUtils#countMatches() from Apache Commons-Collections to do it for you.

@Autowired annotation is defined in the Spring framework.

@Inject annotation is a standard annotation, which is defined in the standard "Dependency Injection for Java" (JSR-330). Spring (since the version 3.0) supports the generalized model of dependency injection which is defined in the standard JSR-330. (Google Guice frameworks and Picocontainer framework also support this model).

With @Inject can be injected the reference to the implementation of the Provider interface, which allows injecting the deferred references.

Annotations @Inject and @Autowired- is almost complete analogies. As well as @Autowired annotation, @Inject annotation can be used for automatic binding properties, methods, and constructors.

In contrast to @Autowired annotation, @Inject annotation has no required attribute. Therefore, if the dependencies will not be found - will be thrown an exception.

There are also differences in the clarifications of the binding properties. If there is ambiguity in the choice of components for the injection the @Named qualifier should be added. In a similar situation for @Autowired annotation will be added @Qualifier qualifier (JSR-330 defines it's own @Qualifier annotation and via this qualifier annotation @Named is defined).

I've found a solution for width: "100%", height: "auto" if you know the aspectRatio (width / height) of the image.

Here's the code:

import { Image, StyleSheet, View } from 'react-native';

const image = () => (
    <View style={styles.imgContainer}>
        <Image style={styles.image} source={require('assets/images/image.png')} />
    </View>
);

const style = StyleSheet.create({
    imgContainer: {
        flexDirection: 'row'
    },
    image: {
        resizeMode: 'contain',
        flex: 1,
        aspectRatio: 1 // Your aspect ratio
    }
});

This is the most simplest way I could get it to work without using onLayout or Dimension calculations. You can even wrap it in a simple reusable component if needed. Give it a shot if anyone is looking for a simple implementation.

If you are having 112 columns in one single table and you would like to insert data from source table, you could do as

create table employees as select * from source_employees where employee_id=100;

Or from sqlplus do as

copy from source_schema/password insert employees using select * from 
source_employees where employee_id=100;

I would do it this way:

UPDATE YourTable SET B = COALESCE(B, A);

COALESCE is a function that returns its first non-null argument.

In this example, if B on a given row is not null, the update is a no-op.

If B is null, the COALESCE skips it and uses A instead.

You can use the row_number() function for this.

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
            row_number() over (order by (select NULL))
    FROM PM_Ingrediants 
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

If you want to start with the maximum already in the table then do:

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
           coalesce(const.maxs, 0) + row_number() over (order by (select NULL))
    FROM PM_Ingrediants cross join
         (select max(sequence) as maxs from PM_Ingrediants_Arrangement_Temp) const
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

Finally, you can just make the sequence column an auto-incrementing identity column. This saves the need to increment it each time:

create table PM_Ingrediants_Arrangement_Temp ( . . .
    sequence int identity(1, 1) -- and might consider making this a primary key too
    . . .
)

Just in case anyone is looking in here for a Sybase version since several of the versions above didn't work

I added some additional lines of code to JS20'07'11's previous Makro to make sure that the name of the sheet's Named Ranges isn't already a name of the workbook's Named Ranges. Without these lines the already definied workbook scooped Named range is deleted and replaced.

I understood that you should use:

Try using the context-application instead of a context-activity

Use rel="external" like below is the example

<li><a href="index.html" rel="external" data-theme="c">Home</a></li>

var secondEmails = (from item in list2
                    select new { Email = item.Email }
                   ).ToList();

var matches = from item in list1
              where !secondEmails.Contains(item.Email)
              select new {Email = item.Email};

case_when(), which was added to dplyr in May 2016, solves this problem in a manner similar to memisc::cases().

For example:

library(dplyr)
mtcars %>% 
  mutate(category = case_when(
    .$cyl == 4 & .$disp < median(.$disp) ~ "4 cylinders, small displacement",
    .$cyl == 8 & .$disp > median(.$disp) ~ "8 cylinders, large displacement",
    TRUE ~ "other"
  )
)

As of dplyr 0.7.0,

mtcars %>% 
  mutate(category = case_when(
    cyl == 4 & disp < median(disp) ~ "4 cylinders, small displacement",
    cyl == 8 & disp > median(disp) ~ "8 cylinders, large displacement",
    TRUE ~ "other"
  )
)

var bodyParser = require('body-parser');
app.use(bodyParser.json());

# convert `dict` to `Series` and replace any blank strings with `None`;
# use the `.dropna()` method and
# then convert back to a `dict`
d_ = pd.Series(d).replace('', None).dropna().to_dict()

print(d_)

    CCS := '0123456789' || 'ABCDEF';
    RNG := 15;

    FOR I IN 1 .. 32 LOOP
      N := TRUNC (RNG * DBMS_RANDOM.VALUE) + 1;
      XSTR := XSTR || SUBSTR (CCS, N, 1);
    END LOOP;

    RETURN SUBSTR(XSTR, 1, 4) || '-' ||

JSONObject json = new JSONObject();
json.put("name", "student");

JSONArray array = new JSONArray();
JSONObject item = new JSONObject();
item.put("information", "test");

item.put("name", "course1");
array.put(item);

json.put("course", array);

message = json.toString();

// message
// {"course":[{"id":3,"information":"test","name":"course1"}],"name":"student"}

Please note that the authors of seaborn only want seaborn.heatmap to work with categorical dataframes. It's not general.

If your index and columns are numeric and/or datetime values, this code will serve you well.

Matplotlib heat-mapping function pcolormesh requires bins instead of indices, so there is some fancy code to build bins from your dataframe indices (even if your index isn't evenly spaced!).

The rest is simply np.meshgrid and plt.pcolormesh.

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

def conv_index_to_bins(index):
    """Calculate bins to contain the index values.
    The start and end bin boundaries are linearly extrapolated from 
    the two first and last values. The middle bin boundaries are 
    midpoints.

    Example 1: [0, 1] -> [-0.5, 0.5, 1.5]
    Example 2: [0, 1, 4] -> [-0.5, 0.5, 2.5, 5.5]
    Example 3: [4, 1, 0] -> [5.5, 2.5, 0.5, -0.5]"""
    assert index.is_monotonic_increasing or index.is_monotonic_decreasing

    # the beginning and end values are guessed from first and last two
    start = index[0] - (index[1]-index[0])/2
    end = index[-1] + (index[-1]-index[-2])/2

    # the middle values are the midpoints
    middle = pd.DataFrame({'m1': index[:-1], 'p1': index[1:]})
    middle = middle['m1'] + (middle['p1']-middle['m1'])/2

    if isinstance(index, pd.DatetimeIndex):
        idx = pd.DatetimeIndex(middle).union([start,end])
    elif isinstance(index, (pd.Float64Index,pd.RangeIndex,pd.Int64Index)):
        idx = pd.Float64Index(middle).union([start,end])
    else:
        print('Warning: guessing what to do with index type %s' % 
              type(index))
        idx = pd.Float64Index(middle).union([start,end])

    return idx.sort_values(ascending=index.is_monotonic_increasing)

def calc_df_mesh(df):
    """Calculate the two-dimensional bins to hold the index and 
    column values."""
    return np.meshgrid(conv_index_to_bins(df.index),
                       conv_index_to_bins(df.columns))

def heatmap(df):
    """Plot a heatmap of the dataframe values using the index and

Call it using heatmap(df), and see it using plt.show().

You should install node.js with nvm, because that way you do not have to provide superuser privileges when installing global packages (you can simply execute "npm install -g packagename" without prepending 'sudo').

Brew is fantastic for other things, however. I tend to be biased towards Bower whenever I have the option to install something with Bower.

You could also use vbCrLf which corresponds to Chr(13) & Chr(10).

I agree with bizl

[XmlInclude(typeof(ParentOfTheItem))]
[Serializable]
public abstract class WarningsType{ }

also if you need to apply this included class to an object item you can do like that

[System.Xml.Serialization.XmlElementAttribute("Warnings", typeof(WarningsType))]
public object[] Items
{
    get
    {
        return this.itemsField;
    }
    set
    {
        this.itemsField = value;
    }
}

Sure, use the .format method. E.g.,

print('{:10s} {:3d}  {:7.2f}'.format('xxx', 123, 98))
print('{:10s} {:3d}  {:7.2f}'.format('yyyy', 3, 1.0))
print('{:10s} {:3d}  {:7.2f}'.format('zz', 42, 123.34))

will print

xxx        123    98.00
yyyy         3     1.00
zz          42   123.34

You can adjust the field sizes as desired. Note that .format works independently of print to format a string. I just used print to display the strings. Brief explanation:

10s format a string with 10 spaces, left justified by default

3d format an integer reserving 3 spaces, right justified by default

7.2f format a float, reserving 7 spaces, 2 after the decimal point, right justfied by default.

There are many additional options to position/format strings (padding, left/right justify etc), String Formatting Operations will provide more information.

Update for f-string mode. E.g.,

text, number, other_number = 'xxx', 123, 98
print(f'{text:10} {number:3d}  {other_number:7.2f}')

For right alignment

print(f'{text:>10} {number:3d}  {other_number:7.2f}')

Just use the style float: left in this way:

<p style="float: left"> Lorem Ipsum </p> 
<form style="float: left">
   <input  type='submit'/>
</form>
<p style="float: left"> Lorem Ipsum </p>

If you are using numpy, printing a single (or multiply) strings to a file can be done with just one line:

numpy.savetxt('Output.txt', ["Purchase Amount: %s" % TotalAmount], fmt='%s')

You better do this syntax

    Code inside the if

The "Premature end of script headers" error message is probably the most loathed and common error message you'll find. What the error actually means, is that the script stopped for whatever reason before it returned any output to the web server. A common cause of this for script writers is to fail to set a content type before printing output code. In Perl for example, before printing any HTML it is necessary to tell the Perl script to set the content type to text/html, this is done by sending a header, like so:

print "Content-type: text/html\n\n";

Or, you can install the GNU version of sed in your Mac, called gsed, and use it using the standard Linux syntax.

For that, install gsed using ports (if you don't have it, get it at http://www.macports.org/) by running sudo port install gsed. Then, you can run sed -i 's/old_link/new_link/g' *

Also check this article. Supposedly Microsoft released their Enterprise Library (v4.0) from their patterns and practices where they cover the validation subject but god knows why they didn't included validation for WPF, so the blog post I'm directing you to, explains what the author did to adapt it. Hope this helps!

You can use

x = [1, 2, 3]
disp(sprintf('Answer: (%d, %d, %d)', x))

This results in

Answer: (1, 2, 3)

For vectors of arbitrary size, you can use

disp(strrep(['Answer: (' sprintf(' %d,', x) ')'], ',)', ')'))

An alternative way would be

disp(strrep(['Answer: (' num2str(x, ' %d,') ')'], ',)', ')'))

If you don't want to use classes (which you really should), the only way to accomplish what you want is by saving the changing styles first:

var oldFontSize = $(this).css("font-size");
var oldBackgroundColor = $(this).css("background-color");

// set style
// do your thing

$(this).css("font-size",oldFontSize);
// etc...

There's a writeup on this article which you might find to be interesting, with some quotes from Jon Skeet. It seems like the use is pretty much the same.

Jon Skeet states that the performance of instance Equals "is slightly better when the strings are short—as the strings increase in length, that difference becomes completely insignificant."

For anybody else stumbling over this, the same happened to me while trying to send a SOAP request header to a SOAP service. The issue was a wrong order in the code, I requested the input stream first before sending the XML body. In the code snipped below, the line InputStream in = conn.getInputStream(); came immediately after ByteArrayOutputStream out = new ByteArrayOutputStream(); which is the incorrect order of things.

ByteArrayOutputStream out = new ByteArrayOutputStream();
// send SOAP request as part of HTTP body 
byte[] data = request.getHttpBody().getBytes("UTF-8");
conn.getOutputStream().write(data); 

if (conn.getResponseCode() != HttpURLConnection.HTTP_OK) {
  Log.d(TAG, "http response code is " + conn.getResponseCode());

FileNotFound in this case was an unfortunate way to encode HTTP response code 400.

You need to get the exact size of the capture like this:

import cv2

cap = cv2.VideoCapture(0)
width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH) + 0.5)
height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT) + 0.5)
size = (width, height)
fourcc = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('your_video.avi', fourcc, 20.0, size)

while(True):
    _, frame = cap.read()
    cv2.imshow('Recording...', frame)
    out.write(frame)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
out.release()
cv2.destroyAllWindows()

This would be really bad to do because sharing your connection string opens up your website to so many vulnerabilities that you can't simply patch up, you have to use a different method if you want it to be secure. Otherwise you are opening up to a huge audience to take advantage of your site.

If you want all the bars to get the same color (fill), you can easily add it inside geom_bar.

ggplot(data=df, aes(x=c1+c2/2, y=c3)) + 
geom_bar(stat="identity", width=c2, fill = "#FF6666")

Add fill = the_name_of_your_var inside aes to change the colors depending of the variable :

c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2)

Use scale_fill_manual() if you want to manually the change of colors.

ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2) + 
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))

Python has some nice functional programming tools that are likely to fit your needs well. Check out lambda functions and map. Also, you're using dicts when it seems like you'd be much better served with lists. For the simple example you provided, try this idiom. Note that map would be better and faster but may not fit your needs:

def mysum(d):
   s = 0  
   for x in d:
        s += x
   return s

def mybigfunction():
   d = (x1, x2, x3, x4, x5, x6, x7, x8, x9)
   return mysum(d)

You mentioned having a lot of local variables, but frankly if you're dealing with lists (or tuples), you should use lists and factor out all those local variables in the long run.

You can parse the date using the Date constructor, then spit out the individual time components:

function convert(str) {_x000D_
  var date = new Date(str),_x000D_
    mnth = ("0" + (date.getMonth() + 1)).slice(-2),_x000D_
    day = ("0" + date.getDate()).slice(-2);_x000D_
  return [date.getFullYear(), mnth, day].join("-");_x000D_
}_x000D_
_x000D_
console.log(convert("Thu Jun 09 2011 00:00:00 GMT+0530 (India Standard Time)"))_x000D_
//-> "2011-06-08"

As you can see from the result though, this will parse the date into the local time zone. If you want to keep the date based on the original time zone, the easiest approach is to split the string and extract the parts you need:

function convert(str) {_x000D_
  var mnths = {_x000D_
      Jan: "01",_x000D_
      Feb: "02",_x000D_
      Mar: "03",_x000D_
      Apr: "04",_x000D_
      May: "05",_x000D_
      Jun: "06",_x000D_
      Jul: "07",_x000D_
      Aug: "08",_x000D_
      Sep: "09",_x000D_
      Oct: "10",_x000D_
      Nov: "11",_x000D_
      Dec: "12"_x000D_
    },_x000D_
    date = str.split(" ");_x000D_
_x000D_
  return [date[3], mnths[date[1]], date[2]].join("-");_x000D_
}_x000D_
_x000D_
console.log(convert("Thu Jun 09 2011 00:00:00 GMT+0530 (India Standard Time)"))_x000D_
//-> "2011-06-09"

1. Try installing VMware tools in guest operating system.
2. Check if firewall is enable
3. If 1 and 2 are ok, try using share internet connection

After sharing connection the VMnet8 IP address will be changed to 192.168.137.1, set up the IP 192.168.18.1 and try again

here is my 2 cents:

Javascript:

$('.scroll').click(function() {
    $('body').animate({
        scrollTop: eval($('#' + $(this).attr('target')).offset().top - 70)
    }, 1000);
});

Html:

<a class="scroll" target="contact">Contact</a>

and the target:

<h2 id="contact">Contact</h2>

If anyone is following all the steps and having no success, make sure that you are using the correct user. I was attempting to use "ec2-user" but I needed to use "ubuntu."

You have to add your jquery script to your chrome-extension project and to the background section of your manifest.json like this :

  "background":
    {
        "scripts": ["thirdParty/jquery-2.0.3.js", "background.js"]
    }

If you need jquery in a content_scripts, you have to add it in the manifest too:

"content_scripts": 
    [
        {
            "matches":["http://website*"],
            "js":["thirdParty/jquery.1.10.2.min.js", "script.js"],
            "css": ["css/style.css"],
            "run_at": "document_end"
        }
    ]

This is what I did.

Also, if I recall correctly, the background scripts are executed in a background window that you can open via chrome://extensions.

As none of the answers above are straight forward:

Backslash escape \ is what you need:

myscript \"test\"

Angular introduced $watchGroup in version 1.3 using which we can watch multiple variables, with a single $watchGroup block $watchGroup takes array as first parameter in which we can include all of our variables to watch.

$scope.$watchGroup(['var1','var2'],function(newVals,oldVals){
   console.log("new value of var1 = " newVals[0]);
   console.log("new value of var2 = " newVals[1]);
   console.log("old value of var1 = " oldVals[0]);
   console.log("old value of var2 = " oldVals[1]);
});

The form tag needs some attributes set:

1. action: The URL that the form data is sent to on submit. Generate it with url_for. It can be omitted if the same URL handles showing the form and processing the data.
2. method="post": Submits the data as form data with the POST method. If not given, or explicitly set to get, the data is submitted in the query string (request.args) with the GET method instead.
3. enctype="multipart/form-data": When the form contains file inputs, it must have this encoding set, otherwise the files will not be uploaded and Flask won't see them.

The input tag needs a name parameter.

Add a view to handle the submitted data, which is in request.form under the same key as the input's name. Any file inputs will be in request.files.

@app.route('/handle_data', methods=['POST'])
def handle_data():
    projectpath = request.form['projectFilepath']
    # your code
    # return a response

Set the form's action to that view's URL using url_for:

<form action="{{ url_for('handle_data') }}" method="post">
    <input type="text" name="projectFilepath">
    <input type="submit">
</form>

For some reason [IgnoreDataMember] does not always work for me, and I sometimes get StackOverflowException (or similar). So instead (or in addition) i've started using a pattern looking something like this when POSTing in Objects to my API:

[Route("api/myroute")]
[AcceptVerbs("POST")]
public IHttpActionResult PostMyObject(JObject myObject)
{
    MyObject myObjectConverted = myObject.ToObject<MyObject>();

    //Do some stuff with the object

    return Ok(myObjectConverted);
}

So basically i pass in an JObject and convert it after it has been recieved to aviod problems caused by the built-in serializer that sometimes cause an infinite loop while parsing the objects.

If someone know a reason that this is in any way a bad idea, please let me know.

It may be worth noting that it is the following code for an EntityFramework Class-property that causes the problem (If two classes refer to each-other):

[Serializable]
public partial class MyObject
{
   [IgnoreDataMember]
   public MyOtherObject MyOtherObject => MyOtherObject.GetById(MyOtherObjectId);
}

[Serializable]
public partial class MyOtherObject
{
   [IgnoreDataMember]
   public List<MyObject> MyObjects => MyObject.GetByMyOtherObjectId(Id);
}

If the pull was the last thing he did then

git reset --hard HEAD~1

You can simply use shell commands. If you want to suppress echoing the output, use the "@" sign. For example:

clean:
    @if [ "test" = "test" ]; then\
        echo "Hello world";\
    fi

Note that the closing ";" and "\" are necessary.

add “| pause” in command arguments box under debugging section at project properties.

(del can be your friend, as it marks objects as being deletable when there no other references to them. Now, often the CPython interpreter keeps this memory for later use, so your operating system might not see the "freed" memory.)

Maybe you would not run into any memory problem in the first place by using a more compact structure for your data. Thus, lists of numbers are much less memory-efficient than the format used by the standard array module or the third-party numpy module. You would save memory by putting your vertices in a NumPy 3xN array and your triangles in an N-element array.

pow() in the cmath library. More info here. Don't forget to put #include<cmath> at the top of the file.

This is a slightly different problem. With me the date picker would display but the css was not loading.

I fixed it by: Reload the theme (go to jquery ui css, line 43 and copy the url there to edit your themeroller theme) > Resave without the advanced options > Replace old files > Try not to change the urls and see if that helps as well.

follow some steps below:

1. open cygwin setup again

2. choose catagory on view tab

3. fill "make" in search tab

4. expand devel

5. find "make: a GNU version of the 'make' ultility", click to install

6. Done!

divclip is an updated version of Florentin Sardan's htmlclipper

with modern enhancements: ES5, HTML5, scoped CSS...

you can programmatically extract a stylized div with:

var html = require("divclip").bySel(".article-body");
console.log(html);

Enjoy.

Here if you are referring to my previous answers Here is an Update. 1. Compile would be removed from the dependencies after 2018.

a new version build Gradle is available.

Use the above-noted stuff it will help you to resolve the errors. It is needed for the developers who are working after March 2018. Also, maven update might be needed. All above answers will not work on the Android Studio 3.1. Hence Above code block is needed to be changed if you are using 3.1. See also I replaced compile by implementation.

I wrote a method for this sometime back. It deletes the specified directory and returns true if the directory deletion was successful.

/**
 * Delets a dir recursively deleting anything inside it.
 * @param dir The dir to delete
 * @return true if the dir was successfully deleted
 */
public static boolean deleteDirectory(File dir) {
    if(! dir.exists() || !dir.isDirectory())    {
        return false;
    }

    String[] files = dir.list();
    for(int i = 0, len = files.length; i < len; i++)    {
        File f = new File(dir, files[i]);
        if(f.isDirectory()) {
            deleteDirectory(f);
        }else   {
            f.delete();
        }
    }
    return dir.delete();
}

There is a much easier way with Regex.

private string FixString(string str)
{
    return string.IsNullOrEmpty(str) ? str : Regex.Replace(str, "[\\D]", "");
}

Just Checkout This :

Solution 1 :

In Subgrid Function You have to write following :

var selectid = $(this).jqGrid('getCell', row_id, 'id');
alert(selectid);

Where row_id is the variable which you define in subgrid as parameter. And id is the column name which you want to get value of the cell.

Solution 2 :

If You Get Jqgrid Row Id In alert Then set your primary key id as key:true In ColModels. So You will get value of your database id in alert. Like this :

{name:"id",index:"id",hidden:true, width:15,key:true, jsonmap:"id"},

I've just checked and i have the same code as you and it works perferctly. The only difference is how i fill my List for the params :

I use a : ArrayList<BasicNameValuePair> params

and fill it this way :

 params.add(new BasicNameValuePair("apikey", apikey);

I do not use any JSONObject to send params to the webservices.

Are you obliged to use the JSONObject ?

See the API docs for java.sql.Statement.

Basically, when you call executeUpdate() or executeQuery(), use the Statement.RETURN_GENERATED_KEYS constant. You can then call getGeneratedKeys to get the auto-generated keys of all rows created by that execution. (Assuming your JDBC driver provides it.)

It goes something along the lines of this:

Statement stmt = conn.createStatement();
stmt.execute(sql, Statement.RETURN_GENERATED_KEYS);
ResultSet keyset = stmt.getGeneratedKeys();

In case you came to this question but related to newer Angular version >= 2.0.

<div [id]="element.id"></div>

PHP has JSON_PRETTY_PRINT option since 5.4.0 (release date 01-Mar-2012).

This should do the job:

$json = json_decode($string);
echo json_encode($json, JSON_PRETTY_PRINT);

See http://www.php.net/manual/en/function.json-encode.php

Note: Don't forget to echo "<pre>" before and "</pre>" after, if you're printing it in HTML to preserve formatting ;)

Why not simply use

function addDays(theDate, days) {
    return new Date(theDate.getTime() + days*24*60*60*1000);
}

var newDate = addDays(new Date(), 5);

or -5 to remove 5 days

If you just want to set the source of the image you can use this.

$("img").attr('src','http://somedomain.com/image.jpg');

Ok, I know there is an accepted answer but… for more special cases you also could use this one:

array_map(function($n) { echo $n['filename']; echo $n['filepath'];},$array);

Or in a more un-complex way:

function printItem($n){
    echo $n['filename'];
    echo $n['filepath'];
}

array_map('printItem', $array);

This will allow you to manipulate the data in an easier way.

I have similar situation, I wanted to test if the user is in a certain group. So, I've created new file utils.py where I put all my small utilities that help me through entire application. There, I've have this definition:

utils.py

def is_company_admin(user):
    return user.groups.filter(name='company_admin').exists()

so basically I am testing if the user is in the group company_admin and for clarity I've called this function is_company_admin.

When I want to check if the user is in the company_admin I just do this:

views.py

from .utils import *

if is_company_admin(request.user):
        data = Company.objects.all().filter(id=request.user.company.id)

Now, if you wish to test same in your template, you can add is_user_admin in your context, something like this:

views.py

return render(request, 'admin/users.html', {'data': data, 'is_company_admin': is_company_admin(request.user)})

Now you can evaluate you response in a template:

users.html

{% if is_company_admin %}
     ... do something ...
{% endif %}

Simple and clean solution, based on answers that can be found earlier in this thread, but done differently. Hope it will help someone.

Tested in Django 3.0.4.

Of the three solutions only Option 1 is polymorphic.

Fields by themselves cannot be overridden. Which is exactly why Option 2 returns the new keyword warning.

The solution to the warning is not to append the “new” keyword, but to implement Option 1.

If you need your field to be polymorphic you need to wrap it in a Property.

Option 3 is OK if you don’t need polymorphic behavior. You should remember though, that when at runtime the property MyInt is accessed, the derived class has no control on the value returned. The base class by itself is capable of returning this value.

This is how a truly polymorphic implementation of your property might look, allowing the derived classes to be in control.

abstract class Parent
{
    abstract public int MyInt { get; }
}

class Father : Parent
{
    public override int MyInt
    {
        get { /* Apply formula "X" and return a value */ }
    }
}

class Mother : Parent
{
    public override int MyInt
    {
        get { /* Apply formula "Y" and return a value */ }
    }
}

If targetSdkVersion is higher than 24, then FileProvider is used to grant access.

Create an xml file(Path: res\xml) provider_paths.xml

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
</paths>

Add a Provider in AndroidManifest.xml

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="${applicationId}.provider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/provider_paths"/>
</provider>

and replace

return Uri.fromFile(getOutputMediaFile(type));

To

               return FileProvider.getUriForFile(this,  BuildConfig.APPLICATION_ID + ".provider", getOutputMediaFile(type));

If it is a list, you can also use AddRange method.

var listB = new List<int>{3, 4, 5};  
var listA = new List<int>{1, 2, 3, 4, 5};

listA.AddRange(listB); // listA now has elements of listB also.

If you need new list (and exclude the duplicate), you can use Union

  var listB = new List<int>{3, 4, 5};  
  var listA = new List<int>{1, 2, 3, 4, 5};
  var listFinal = listA.Union(listB);

If you need new list (and include the duplicate), you can use Concat

  var listB = new List<int>{3, 4, 5};  
  var listA = new List<int>{1, 2, 3, 4, 5};
  var listFinal = listA.Concat(listB);

If you need common items, you can use Intersect.

var listB = new List<int>{3, 4, 5};  
var listA = new List<int>{1, 2, 3, 4};  
var listFinal = listA.Intersect(listB); //3,4

to position the dialog in the center of the screen :

$('#my-selector').parent().position({
                    my: "center",
                    at: "center",
                    of: window
});

To be honest - there aren't any free alternatives to MS Access. At least if you mean database development tool (forms, reports, queries, VBA support etc.). If you think about MS Access as a database engine (you mean MS Jet or ACE in fact) then yes - you have a lot of possibilities. There are a lot of free database engines - the most popular are MySQL and PostgreSQL. I can recommend both - it depends what you want to do.

For writing database frontends C++ is one of the worst choices. You should consider MS Visual C#, MS Visual Basic .NET or... Even Java/Swing (if we are talking about desktop application). If you think about the web-enabled frontend - consider PHP (with MySQL or PostgreSQL on the backend) or ASP.NET (with MSSQL Server at the backend).

I strongly recommend you not to use C++ for such job. This language is very efficient and flexible, but advanced database frontend development with C++ is not the best idea. C++ is great in system programming, games development, maths and physics simulations, everywhere where efficiency is the key - like real-time applications etc. Frontends don't have to be daemons of speed - they should look nice and have advanced end-user features (like sorting, coloring etc.). If you are looking for free tools - maybe C# Express or Visual Basic.NET Express 2008 would be the proper choice? Or maybe Java/Swing (check the NetBeans IDE)? Maybe SharpDevelop? But not C++... Leave C++ for the things it suits the best.

Hibernate is not going to make it easy for you to do what you are trying to do. From the Hibernate documentation:

Note that when using referencedColumnName to a non primary key column, the associated class has to be Serializable. Also note that the referencedColumnName to a non primary key column has to be mapped to a property having a single column (other cases might not work). (emphasis added)

So if you are unwilling to make AnEmbeddableObject the Identifier for Bar then Hibernate is not going to lazily, automatically retrieve Bar for you. You can, of course, still use HQL to write queries that join on AnEmbeddableObject, but you lose automatic fetching and life cycle maintenance if you insist on using a multi-column non-primary key for Bar.

Echo inside an HTML element with class and style the element:

echo "<span class='name'>" . $ip['cityName'] . "</span>";

You want reorder(). Here is an example with dummy data

set.seed(42)
df <- data.frame(Category = sample(LETTERS), Count = rpois(26, 6))

require("ggplot2")

p1 <- ggplot(df, aes(x = Category, y = Count)) +
         geom_bar(stat = "identity")

p2 <- ggplot(df, aes(x = reorder(Category, -Count), y = Count)) +
         geom_bar(stat = "identity")

require("gridExtra")
grid.arrange(arrangeGrob(p1, p2))

Giving:

Use reorder(Category, Count) to have Category ordered from low-high.

You could use the undocumented

DBCC LOG(databasename, typeofoutput)

where typeofoutput:

0: Return only the minimum of information for each operation -- the operation, its context and the transaction ID. (Default)
1: As 0, but also retrieve any flags and the log record length.
2: As 1, but also retrieve the object name, index name, page ID and slot ID.
3: Full informational dump of each operation.
4: As 3 but includes a hex dump of the current transaction log row.

For example, DBCC LOG(database, 1)

You could also try fn_dblog.

For rolling back a transaction using the transaction log I would take a look at Stack Overflow post Rollback transaction using transaction log.

The best solution I've been able to come up with is to include an "onmouseenter" attribute on your element like this:

<button type="button" class="btn btn-default" 
    data-placement="left"
    title="Tooltip on left"
    onmouseenter="$(this).tooltip('show')">
</button>

In my application, it was enough to use:

myclassname.this

The general form of the syntax is

<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>[#<commit-ish> | #semver:<semver>]

which means for your case it will be

npm install git+ssh://[email protected]/visionmedia/express.git

From npmjs docs:

npm install :

Installs the package from the hosted git provider, cloning it with git. For a full git remote url, only that URL will be attempted.

<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>[#<commit-ish>

| #semver:] is one of git, git+ssh, git+http, git+https, or git+file.

If # is provided, it will be used to clone exactly that commit. If the commit-ish has the format #semver:, can be any valid semver range or exact version, and npm will look for any tags or refs matching that range in the remote repository, much as it would for a registry dependency. If neither # or

semver: is specified, then master is used.

If the repository makes use of submodules, those submodules will be cloned as well.

If the package being installed contains a prepare script, its dependencies and devDependencies will be installed, and the prepare script will be run, before the package is packaged and installed.

The following git environment variables are recognized by npm and will be added to the environment when running git:

• GIT_ASKPASS
• GIT_EXEC_PATH
• GIT_PROXY_COMMAND
• GIT_SSH
• GIT_SSH_COMMAND
• GIT_SSL_CAINFO GIT_SSL_NO_VERIFY

See the git man page for details.

Examples:

npm install git+ssh://[email protected]:npm/npm.git#v1.0.27
npm install git+ssh://[email protected]:npm/npm#semver:^5.0
npm install git+https://[email protected]/npm/npm.git
npm install git://github.com/npm/npm.git#v1.0.27
GIT_SSH_COMMAND='ssh -i ~/.ssh/custom_ident' npm install git+ssh://[email protected]:npm/npm.git npm install

For Windows users: Try deleting files: java.exe, javaw.exe and javaws.exe from Windows\System32

My issue was the java version 1.7 installed.

You are reinventing the wheel. Normal PowerShell scripts have parameters starting with -, like script.ps1 -server http://devserver

Then you handle them in param section in the beginning of the file.

You can also assign default values to your params, read them from console if not available or stop script execution:

 param (
    [string]$server = "http://defaultserver",
    [Parameter(Mandatory=$true)][string]$username,
    [string]$password = $( Read-Host "Input password, please" )
 )

Inside the script you can simply

write-output $server

since all parameters become variables available in script scope.

In this example, the $server gets a default value if the script is called without it, script stops if you omit the -username parameter and asks for terminal input if -password is omitted.

Update: You might also want to pass a "flag" (a boolean true/false parameter) to a PowerShell script. For instance, your script may accept a "force" where the script runs in a more careful mode when force is not used.

The keyword for that is [switch] parameter type:

 param (
    [string]$server = "http://defaultserver",
    [string]$password = $( Read-Host "Input password, please" ),
    [switch]$force = $false
 )

Inside the script then you would work with it like this:

if ($force) {
  //deletes a file or does something "bad"
}

Now, when calling the script you'd set the switch/flag parameter like this:

.\yourscript.ps1 -server "http://otherserver" -force

If you explicitly want to state that the flag is not set, there is a special syntax for that

.\yourscript.ps1 -server "http://otherserver" -force:$false

• about_Functions
• about_Functions_Advanced_Parameters

I encountered this error when I use Mysql Cluster, I do not know this question is from a cluster usage or not. As the error is exactly the same, so give my solution here. Getting this error because the data nodes suddenly crash. But when the nodes crash, you can still get the correct result using cmd:

ndb_mgm -e 'ALL REPORT MEMORYUSAGE'

And the mysqld also works correctly.So at first, I can not understand what is wrong. And about 5 mins later, ndb_mgm result shows no data node working. Then I realize the problem. So, try to restart all the data nodes, then the mysql server is back and everything is OK.

But one thing is weird to me, after I lost mysql server for some queries, when I use cmd like show tables, I can still get the return info like 33 rows in set (5.57 sec), but no table info is displayed.

Hmm, there are many solution written for php version lower than 7.1.

Here is an other simple one for those who doesn't want catch all exception and can't make common interfaces:

<?php
$ex = NULL
try {
    /* ... */
} catch (FirstException $ex) {
    // just do nothing here
} catch (SecondException $ex) {
    // just do nothing here
}
if ($ex !== NULL) {
    // handle those exceptions here!
}
?>

I think that Git on Dropbox is great. I use it all the time. I have multiple computers (two at home and one at work) on which I use Dropbox as a central bare repository. Since I don’t want to host it on a public service, and I don’t have access to a server that I can always SSH to, Dropbox takes care of this by syncing in the background (very doing so quickly).

Setup is something like this:

~/project $ git init
~/project $ git add .
~/project $ git commit -m "first commit"
~/project $ cd ~/Dropbox/git

~/Dropbox/git $ git init --bare project.git
~/Dropbox/git $ cd ~/project

~/project $ git remote add origin ~/Dropbox/git/project.git
~/project $ git push -u origin master

From there, you can just clone that ~/Dropbox/git/project.git directory (regardless of whether it belongs to your Dropbox account or is shared across multiple accounts) and do all the normal Git operations—they will be synchronized to all your other machines automatically.

I wrote a blog post “On Version Control” in which I cover the reasoning behind my environment setup. It’s based on my Ruby on Rails development experience, but it can be applied to anything, really.

You can also achieve it by iterating over your String and using a switch to check each individual character, adding a counter whenever it finds a match. Ah, maybe some code will make it clearer:

Main Application:

public static void main(String[] args) {

        String test = "The quick brown fox jumped over the lazy dog.";

        int countA = 0, countO = 0, countSpace = 0, countDot = 0;

        for (int i = 0; i < test.length(); i++) {
            switch (test.charAt(i)) {
                case 'a':
                case 'A': countA++; break;
                case 'o':
                case 'O': countO++; break;
                case ' ': countSpace++; break;
                case '.': countDot++; break;
            }
        }

        System.out.printf("%s%d%n%s%d%n%s%d%n%s%d", "A: ", countA, "O: ", countO, "Space: ", countSpace, "Dot: ", countDot);

    }

Output:

A: 1
O: 4
Space: 8
Dot: 1

The solutions using hasattr(obj, '__call__') and callable(.) mentioned in some of the answers have a main drawback: both also return True for classes and instances of classes with a __call__() method. Eg.

>>> import collections
>>> Test = collections.namedtuple('Test', [])
>>> callable(Test)
True
>>> hasattr(Test, '__call__')
True

One proper way of checking if an object is a user-defined function (and nothing but a that) is to use isfunction(.):

>>> import inspect
>>> inspect.isfunction(Test)
False
>>> def t(): pass
>>> inspect.isfunction(t)
True

If you need to check for other types, have a look at inspect — Inspect live objects.

The current answer for Swift 2.x and higher (from the Swift Programming Language guide on Collection Types) seems to be to either iterate over the Set entries like so:

for item in myItemSet {
   ...
}

Or, to use the "sorted" method:

let itemsArray = myItemSet.sorted()

It seems the Swift designers did not like allObjects as an access mechanism because Sets aren't really ordered, so they wanted to make sure you didn't get out an array without an explicit ordering applied.

If you don't want the overhead of sorting and don't care about the order, I usually use the map or flatMap methods which should be a bit quicker to extract an array:

let itemsArray = myItemSet.map { $0 }

Which will build an array of the type the Set holds, if you need it to be an array of a specific type (say, entitles from a set of managed object relations that are not declared as a typed set) you can do something like:

var itemsArray : [MyObjectType] = []
if let typedSet = myItemSet as? Set<MyObjectType> {
 itemsArray = typedSet.map { $0 }
}

@Shoban It looks like the question is tagged c# so here is the appropriate snipped http://msdn.microsoft.com/en-us/library/system.windows.forms.datetimepicker.value.aspx

    // Create a new DateTimePicker
    DateTimePicker dateTimePicker1 = new DateTimePicker();
    Controls.Add(dateTimePicker1);
    MessageBox.Show(dateTimePicker1.Value.ToString());

    dateTimePicker1.Value = DateTime.Now.AddDays(1);
    MessageBox.Show(dateTimePicker1.Value.ToString());
 } 

@gbtimmon's answer is great, but way, way too complicated. I've simplified his code as much as I could.

This happened to me after I ran a script with cProfile a la python3 -m cProfile script.py even though xlrd was already installed and had never thrown this error before. it persisted even under python3 script.py. (Granted, I agree this wasn't what happened to OP, given the obvious import error)

However, for cases like mine, the following fixed the issue, despite being told "requirement already met" in every case.

pip install --upgrade pandas
pip install --upgrade xlrd

Pretty confounding stuff; not sure if cProfile was the cause or just a coincidence

The following should work, assuming your pip install operated on python2.

python3 -m pip install xlrd

Just pieced this together for the same problem:

before_filter :validate_params

private

def validate_params
  return head :bad_request unless params_present?
end

def params_present?  
  Set.new(%w(one two three)) <= (Set.new(params.keys)) &&
  params.values.all?
end

the first line checks if our target keys are present in the params' keys using the <= subset? operator. Enumerable.all? without block per default returns false if any value is nil or false.

'\r' means 'carriage return' and it is similar to '\n' which means 'line break' or more commonly 'new line'

in the old days of typewriters, you would have to move the carriage that writes back to the start of the line, and move the line down in order to write onto the next line.

in the modern computer era we still have this functionality for multiple reasons. but mostly we use only '\n' and automatically assume that we want to start writing from the start of the line, since it would not make much sense otherwise.

however, there are some times when we want to use JUST the '\r' and that would be if i want to write something to an output, and the instead of going down to a new line and writing something else, i want to write something over what i already wrote, this is how many programs in linux or in windows command line are able to have 'progress' information that changes on the same line.

nowadays most systems use only the '\n' to denote a newline. but some systems use both together.

you can see examples of this given in some of the other answers, but the most common are:

• windows ends lines with '\r\n'
• mac ends lines with '\r'
• unix/linux use '\n'

and some other programs also have specific uses for them.

In the case you need to manually 'exit' a transaction through code (be it through an exception or simply checking an error state) you shouldn't use DB::transaction() but instead wrap your code in DB::beginTransaction and DB::commit/DB::rollback():

DB::beginTransaction();

try {
    DB::insert(...);
    DB::insert(...);
    DB::insert(...);

    DB::commit();
    // all good
} catch (\Exception $e) {
    DB::rollback();
    // something went wrong
}

See the transaction docs.

Yes, it's historical. Without it, it creates an old-style class.

If you use type() on an old-style object, you just get "instance". On a new-style object you get its class.

I usually have scss file associated to each React component. But, I don't see reason why you wouldn't encapsulate the component with logic and look in it. I mean, you have similar thing with web components.

There are 2 options to find matching text; string.match or string.find.

Both of these perform a regex search on the string to find matches.

string.find()

string.find(subject string, pattern string, optional start position, optional plain flag)

Returns the startIndex & endIndex of the substring found.

The plain flag allows for the pattern to be ignored and intead be interpreted as a literal. Rather than (tiger) being interpreted as a regex capture group matching for tiger, it instead looks for (tiger) within a string.

Going the other way, if you want to regex match but still want literal special characters (such as .()[]+- etc.), you can escape them with a percentage; %(tiger%).

You will likely use this in combination with string.sub

Example

str = "This is some text containing the word tiger."
if string.find(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

string.match()

string.match(s, pattern, optional index)

Returns the capture groups found.

Example

str = "This is some text containing the word tiger."
if string.match(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

When using a glob pattern, a question mark represents a single character and an asterisk represents a sequence of zero or more characters:

if [[ $gg == ????grid* ]] ; then echo $gg; fi

When using a regular expression, a dot represents a single character and an asterisk represents zero or more of the preceding character. So ".*" represents zero or more of any character, "a*" represents zero or more "a", "[0-9]*" represents zero or more digits. Another useful one (among many) is the plus sign which represents one or more of the preceding character. So "[a-z]+" represents one or more lowercase alpha character (in the C locale - and some others).

if [[ $gg =~ ^....grid.*$ ]] ; then echo $gg; fi

You would need to restart the Postgresql Server.

If you are using ubuntu you can restart Postgresql by following command

This post shows a complete working HTML file as an example of triggering code to run when a tab is clicked. The .on() method is now the way that jQuery suggests that you handle events.

jQuery development history

To make something happen when the user clicks a tab can be done by giving the list element an id.

<li id="list">

Then referring to the id.

$("#list").on("click", function() {
 alert("Tab Clicked!");
});

Make sure that you are using a current version of the jQuery api. Referencing the jQuery api from Google, you can get the link here:

for a big database you should either remove the database from the disk (after you stop the engine first I guess) or use in Cypher something like:

MATCH (n)
OPTIONAL MATCH (n)-[r]-()
WITH n,r LIMIT 50000
DELETE n,r
RETURN count(n) as deletedNodesCount

see https://zoomicon.wordpress.com/2015/04/18/howto-delete-all-nodes-and-relationships-from-neo4j-graph-database/ for some more info I've gathered on this from various answers

Using split and regex :

    var str = "fooBar0123".split(/(\d+)/);
    console.log(str[0]); // fooBar
    console.log(str[1]); // 0123

You need to include the protocol scheme:

'http://192.168.1.61:8080/api/call'

Without the http:// part, requests has no idea how to connect to the remote server.

Note that the protocol scheme must be all lowercase; if your URL starts with HTTP:// for example, it won’t find the http:// connection adapter either.

The second method would almost certainly be the fastest way to test whether a null-terminated string is empty, since it involves one read and one comparison. There's certainly nothing wrong with this approach in this case, so you may as well use it.

The third method doesn't check whether a character array is empty; it ensures that a character array is empty.

The packages you installed introduced dependencies to version 5.2.3.0 dll's as user Bracher showed above. Microsoft.AspNet.WebApi.Cors is an example package. The path I take is to update the MVC project proir to any package installs:

Install-Package Microsoft.AspNet.Mvc -Version 5.2.3

https://www.nuget.org/packages/microsoft.aspnet.mvc

You may try this example:

<form>_x000D_
  <h1>Hello! I'm duke! What's you name?</h1>_x000D_
  <input type="text" name="user">_x000D_
  <br>_x000D_
  <br>_x000D_
  <input type="submit" value="submit">&nbsp;&nbsp;&nbsp;&nbsp;_x000D_
  <input type="reset">_x000D_
</form>_x000D_
<h1>Hello ${param.user}</h1> _x000D_
<!-- its Expression Language -->

Main classes should be under src/main/java
and
test classes should be under src/test/java

If all in the correct places and still main classes are not accessible then
Right click project => Maven => Update Project
Hope so this will resolve the issue

You can do this:

<div class"my_class">
<?php if ($cart->count_product > 0) {
          print $cart->count_product; 
      } else { 
          print ''; 
      } 
?>
</div>

Before hitting the div, we are not in PHP tags

New Note: You probably don't want or need to do this. What you probably want to do is just put those types of command dependencies for build/test etc. in the devDependencies section of your package.json. Anytime you use something from scripts in package.json your devDependencies commands (in node_modules/.bin) act as if they are in your path.

For example:

npm i --save-dev mocha # Install test runner locally
npm i --save-dev babel # Install current babel locally

Then in package.json:

// devDependencies has mocha and babel now

"scripts": {
  "test": "mocha",
  "build": "babel -d lib src",
  "prepublish": "babel -d lib src"
}

Then at your command prompt you can run:

npm run build # finds babel
npm test # finds mocha

npm publish # will run babel first

But if you really want to install globally, you can add a preinstall in the scripts section of the package.json:

"scripts": {
  "preinstall": "npm i -g themodule"
}

So actually my npm install executes npm install again .. which is weird but seems to work.

Note: you might have issues if you are using the most common setup for npm where global Node package installs required sudo. One option is to change your npm configuration so this isn't necessary:

npm config set prefix ~/npm, add $HOME/npm/bin to $PATH by appending export PATH=$HOME/npm/bin:$PATH to your ~/.bashrc.

To get JSON quickly into Java objects (Maps) that you can then 'drill' and work with, you can use json-io (https://github.com/jdereg/json-io). This library will let you read in a JSON String, and get back a 'Map of Maps' representation.

If you have the corresponding Java classes in your JVM, you can read the JSON in and it will parse it directly into instances of the Java classes.

JsonReader.jsonToMaps(String json)

where json is the String containing the JSON to be read. The return value is a Map where the keys will contain the JSON fields, and the values will contain the associated values.

JsonReader.jsonToJava(String json) 

will read the same JSON string in, and the return value will be the Java instance that was serialized into the JSON. Use this API if you have the classes in your JVM that were written by

JsonWriter.objectToJson(MyClass foo).

for word in d:
    if d in paid[j]:
         do_something()

will try all the words in the list d and check if they can be found in the string paid[j].

This is not very efficient since paid[j] has to be scanned again for each word in d. You could also use two sets, one composed of the words in the sentence, one of your list, and then look at the intersection of the sets.

sentence = "words don't come easy"
d = ["come", "together", "easy", "does", "it"]

s1 = set(sentence.split())
s2 = set(d)

print (s1.intersection(s2))

Output:

{'come', 'easy'}

tl;dr

LocalDateTime.parse(           // Parse into an object representing a date with a time-of-day but without time zone and without offset-from-UTC.
    "2014/10/29 18:10:45"      // Convert input string to comply with standard ISO 8601 format.
    .replace( " " , "T" )      // Replace SPACE in the middle with a `T`.
    .replace( "/" , "-" )      // Replace SLASH in the middle with a `-`.
)
.atZone(                       // Apply a time zone to provide the context needed to determine an actual moment.
    ZoneId.of( "Europe/Oslo" ) // Specify the time zone you are certain was intended for that input.
)                              // Returns a `ZonedDateTime` object.
.toInstant()                   // Adjust into UTC.
.toEpochMilli()                // Get the number of milliseconds since first moment of 1970 in UTC, 1970-01-01T00:00Z.

Time Zone

The accepted answer is correct, except that it ignores the crucial issue of time zone. Is your input string 6:10 PM in Paris or Montréal? Or UTC?

Use a proper time zone name. Usually a continent plus city/region. For example, "Europe/Oslo". Avoid the 3 or 4 letter codes which are neither standardized nor unique.

java.time

The modern approach uses the java.time classes.

Alter your input to conform with the ISO 8601 standard. Replace the SPACE in the middle with a T. And replace the slash characters with hyphens. The java.time classes use these standard formats by default when parsing/generating strings. So no need to specify a formatting pattern.

String input = "2014/10/29 18:10:45".replace( " " , "T" ).replace( "/" , "-" ) ;
LocalDateTime ldt = LocalDateTime.parse( input ) ;

A LocalDateTime, like your input string, lacks any concept of time zone or offset-from-UTC. Without the context of a zone/offset, a LocalDateTime has no real meaning. Is it 6:10 PM in India, Europe, or Canada? Each of those places experience 6:10 PM at different moments, at different points on the timeline. So you must specify which you have in mind if you want to determine a specific point on the timeline.

ZoneId z = ZoneId.of( "Europe/Oslo" ) ;
ZonedDateTime zdt = ldt.atZone( z ) ;  

Now we have a specific moment, in that ZonedDateTime. Convert to UTC by extracting a Instant. The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Instant instant = zdt.toInstant() ;

Now we can get your desired count of milliseconds since the epoch reference of first moment of 1970 in UTC, 1970-01-01T00:00Z.

long millisSinceEpoch = instant.toEpochMilli() ; 

Be aware of possible data loss. The Instant object is capable of carrying microseconds or nanoseconds, finer than milliseconds. That finer fractional part of a second will be ignored when getting a count of milliseconds.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Joda-Time

Update: The Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes. I will leave this section intact for history.

Below is the same kind of code but using the Joda-Time 2.5 library and handling time zone.

The java.util.Date, .Calendar, and .SimpleDateFormat classes are notoriously troublesome, confusing, and flawed. Avoid them. Use either Joda-Time or the java.time package (inspired by Joda-Time) built into Java 8.

ISO 8601

Your string is almost in ISO 8601 format. The slashes need to be hyphens and the SPACE in middle should be replaced with a T. If we tweak that, then the resulting string can be fed directly into constructor without bothering to specify a formatter. Joda-Time uses ISO 8701 formats as it's defaults for parsing and generating strings.

Example Code

String inputRaw = "2014/10/29 18:10:45";
String input = inputRaw.replace( "/", "-" ).replace( " ", "T" );
DateTimeZone zone = DateTimeZone.forID( "Europe/Oslo" ); // Or DateTimeZone.UTC
DateTime dateTime = new DateTime( input, zone );
long millisecondsSinceUnixEpoch = dateTime.getMillis();

I am sure you could make a little SOAP client with Axis. Axis installation instructions.

follow these steps. 1:- create your configuration class like below you can see

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.beans.factory.annotation.Value;

@Configuration
public class YourConfiguration{

    // passing the key which you set in application.properties
    @Value("${userBucket.path}")
    private String userBucket;

   // getting the value from that key which you set in application.properties
    @Bean
    public String getUserBucketPath() {
        return userBucket;
    }
}

2:- when you have a configuration class then inject in the variable from a configuration where you need.

@Component
public class YourService {

    @Autowired
    private String getUserBucketPath;

    // now you have a value in getUserBucketPath varibale automatically.
}

Using a subshell substitution to parse the words undoes all the work you are doing to put spaces together.

Try instead:

cat CSV_file | sed -n 1'p' | tr ',' '\n' | while read word; do
    echo $word
done

That also increases parallelism. Using a subshell as in your question forces the entire subshell process to finish before you can start iterating over the answers. Piping to a subshell (as in my answer) lets them work in parallel. This matters only if you have many lines in the file, of course.

You can see Silverlight/WPF sets ellipse with hexadecimal colour for using a hex value:

your_contorl.Color = DirectCast(ColorConverter.ConvertFromString("#D8E0A627"), Color)

[self dismissModalViewControllerAnimated:NO]; has been deprecated.

Use [self dismissViewControllerAnimated:NO completion:nil]; instead.

So basically I just made another div to wrap the pink and yellow, and I make that div have a float:left on it. The blue div has a float:right on it.

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

result.push(...data);

If you are testing asynchronous code, you need to make sure to place done() in the callback of that asynchronous code. I had that issue when testing http requests to a REST API.

Might be late to answer - if you don't want to modify your current code a lot and still be able to have similar validation code all over your project, you may try this one too - https://github.com/vishalvisd/react-validator.

I would add an identifying Id or class to the dropbox and remove using Javascript.

The article here should help.

Here is the code

<html>
   <body>
      <input type="text" name="name" id="name" required="required"                                    aria-required="true" pattern="[a-z]{1,5}" onchange="func()">
      <script>
       function func()
       {
        var namdata=document.form1.name.value;
         if(namdata.match("[a-z]{1,5}"))
        {
         document.getElementById("but1").disabled=false;
        }
        }
        </script>
  </body>
</html>

Using Javascript

Use anonymous class

Shape your model the way you want using anonymous classes:

var root = new 
{ 
    car = new 
    { 
        name = "Ford", 
        owner = "Henry"
    }
};

string json = JsonConvert.SerializeObject(root);

Database is a collection of schemas and schema is a collection of tables. But in MySQL they use it the same way.

As mentioned by Dan Abramov

Do it right inside render

We actually use that approach with memoise one for any kind of proxying props to state calculations.

Our code looks this way

// ./decorators/memoized.js  
import memoizeOne from 'memoize-one';

export function memoized(target, key, descriptor) {
  descriptor.value = memoizeOne(descriptor.value);
  return descriptor;
}

// ./components/exampleComponent.js
import React from 'react';
import { memoized } from 'src/decorators';

class ExampleComponent extends React.Component {
  buildValuesFromProps() {
    const {
      watchedProp1,
      watchedProp2,
      watchedProp3,
      watchedProp4,
      watchedProp5,
    } = this.props
    return {
      value1: buildValue1(watchedProp1, watchedProp2),
      value2: buildValue2(watchedProp1, watchedProp3, watchedProp5),
      value3: buildValue3(watchedProp3, watchedProp4, watchedProp5),
    }
  }

  @memoized
  buildValue1(watchedProp1, watchedProp2) {
    return ...;
  }

  @memoized
  buildValue2(watchedProp1, watchedProp3, watchedProp5) {
    return ...;
  }

  @memoized
  buildValue3(watchedProp3, watchedProp4, watchedProp5) {
    return ...;
  }

  render() {
    const {
      value1,
      value2,
      value3
    } = this.buildValuesFromProps();

    return (
      <div>
        <Component1 value={value1}>
        <Component2 value={value2}>
        <Component3 value={value3}>
      </div>
    );
  }
}

The benefits of it are that you don't need to code tons of comparison boilerplate inside getDerivedStateFromProps or componentWillReceiveProps and you can skip copy-paste initialization inside a constructor.

NOTE:

This approach is used only for proxying the props to state, in case you have some inner state logic it still needs to be handled in component lifecycles.

In addition to the answer of "dasblinkenlight" I think an example could help. I will only use 8 bits for a better understanding.

x & 1 produces a value that is either 1 or 0, depending on the least significant bit of x: if the last bit is 1, the result of x & 1 is 1; otherwise, it is 0. This is a bitwise AND operation.

This is because 1 will be represented in bits as 00000001. Only the last bit is set to 1. Let's assume x is 185 which will be represented in bits as 10111001. If you apply a bitwise AND operation on x with 1 this will be the result:

00000001
10111001
--------
00000001

The first seven bits of the operation result will be 0 after the operation and will carry no information in this case (see Logical AND operation). Because whatever the first seven bits of the operand x were before, after the operation they will be 0. But the last bit of the operand 1 is 1 and it will reveal if the last bit of operand x was 0 or 1. So in this example the result of the bitwise AND operation will be 1 because our last bit of x is 1. If the last bit would have been 0, then the result would have been also 0, indicating that the last bit of operand x is 0:

00000001
10111000
--------
00000000

x >>= 1 means "set x to itself shifted by one bit to the right". The expression evaluates to the new value of x after the shift

Let's pick the example from above. For x >>= 1 this would be:

10111001
--------
01011100

And for left shift x <<= 1 it would be:

10111001
--------
01110010

Please pay attention to the note of user "dasblinkenlight" in regard to shifts.

Applying

    <item name="android:statusBarColor">@color/color_primary_dark</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>

in Theme.AppCompat.Light.DarkActionBar didn't worked for me. What did the trick is , giving colorPrimaryDark as usual along with android:colorPrimary in styles.xml

<item name="android:colorAccent">@color/color_primary</item>
<item name="android:colorPrimary">@color/color_primary</item>
<item name="android:colorPrimaryDark">@color/color_primary_dark</item>

and in setting

if (Build.VERSION.SdkInt >= BuildVersionCodes.Lollipop)
                {
                    Window window = this.Window;
                    Window.AddFlags(WindowManagerFlags.DrawsSystemBarBackgrounds);
                }

didn't had to set statusbar color in code .

Here's a very simple example for swift Classes ONLY, and not for structures or enumerations. Note that the protocol method being optional, has two levels of optional chaining at play. Also the class adopting the protocol needs the @objc attribute in its declaration.

@objc protocol CollectionOfDataDelegate{
   optional func indexDidChange(index: Int)
}


@objc class RootView: CollectionOfDataDelegate{

    var data = CollectionOfData()

   init(){
      data.delegate = self
      data.indexIsNow()
   }

  func indexDidChange(index: Int) {
      println("The index is currently: \(index)")
  }

}

class CollectionOfData{
    var index : Int?
    weak var delegate : CollectionOfDataDelegate?

   func indexIsNow(){
      index = 23
      delegate?.indexDidChange?(index!)
    }

 }

Use OpenID Connect or User-Managed Access.

As nothing is more efficient than not doing it at all.

Things have evolved in Facebooks approach, I now realised that you need to "Add Product" to your App: facebook login. make sure oauth & web auth on add my own site url to ""Valid Auth redirect URI" (and removed the default https://www.facebook.com/connect/login_success.html which his in the

Without this I get the URL Blocked error.

I am having OpenCV version 3.4.3 on MacOS. I was getting the same error as above.

I changed my code from

frame = cv2.resize(frame, (0,0), fx=0.5, fy=0.5)   

to

frame = cv2.resize(frame, None, fx=0.5, fy=0.5)    

Now its working fine for me.

Build the project Locate the .exe file in your favorite file explorer.

I have the same issue with the Manage NuGet Packages dialog, I use a work-around that may help others - running from package manager console:

If I use the command line powershell commandlet install-package, all is fine.

I am adverse to changing a security setting "just to make it work".

var value = (uint) Enum.Parse(typeof(baseKey), "HKEY_LOCAL_MACHINE");  

Please use the below line of code in script object which is there in package.json

"scripts": {
    "start": "webpack-dev-server --hot"
}

For me it worked perfectly fine.

Off course an old question. But I have a simple solution where no need of Looping, CTE, Table variables etc.

DECLARE @MyVar datetime = '1/1/2010'    
SELECT @MyVar

SELECT DATEADD (DD,NUMBER,@MyVar) 
FROM master.dbo.spt_values 
WHERE TYPE='P' AND NUMBER BETWEEN 0 AND 4 
ORDER BY NUMBER

Note : spt_values is a Mircrosoft's undocumented table. It has numbers for every type. Its not suggestible to use as it can be removed in any new versions of sql server without prior information, since it is undocumented. But we can use it as quick workaround in some scenario's like above.

With Prototype, you can also do:

HTML:

<ul id="mylist"></ul>

JS:

$('mylist').insert('<li>text</li>');

<android.support.v7.widget.SwitchCompat
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/adamSwitch"
    android:textColor="@color/top_color"
    android:textAppearance="@color/top_color"
    android:gravity="center"
    app:showText="true"
    app:theme="@style/Custom.Widget.SwitchCompat"
    app:switchPadding="5dp"
    />

in style.xml

<style name="Custom.Widget.SwitchCompat" parent="Widget.AppCompat.CompoundButton.Switch" >
            <item name="android:textColorPrimary">@color/blue</item>  <!--textColor on activated state -->
      </style>

It's one of those annoying functions that you might not want to re-implement:

from annoying.functions import get_object_or_None
#...
user = get_object_or_None(Content, name="baby")
