echo "${req}"

a) Open the "php.ini". For XAMPP,it is located in C:\XAMPP\php\php.ini. Find out if you are using WAMP or LAMP server. Note : Make a backup of php.ini file 

b) Search [mail function] in the php.ini file. 

You can find like below.
[mail function]
; For Win32 only.
; http://php.net/smtp
SMTP = localhost
; http://php.net/smtp-port
smtp_port = 25


; For Win32 only.
; http://php.net/sendmail-from
;sendmail_from = postmaster@localhost


Change the localhost to the smtp server name of your ISP. No need to change the smtp_port. Leave it as 25. Change sendmail_from from postmaster@localhost to your domain email address which will be used as from address.. 

So for me, it will become like this.
[mail function]
; For Win32 only.
SMTP = smtp.planetghost.com
smtp_port = 25
; For Win32 only.
sendmail_from = [email protected]
auth_username = [email protected]
auth_password = example_password


c) Restart the XAMPP or WAMP(apache server) so that changes will start working.

d) Now try to send the mail using the mail() function , 

mail("[email protected]","Success","Great, Localhost Mail works");

Another way

Gmail servers use SMTP Authentication under SSL. I think that there is no way to use the mail() function under that circumstances, so you might want to check these alternatives:

1. PEAR: Mail
2. phpMailer

They both support SMTP auth under SSL.

        Current = default;
    }

    public LineEnumerator GetEnumerator() => this;

        if (Text.IsEmpty) return false;

        var index = Text.IndexOf( '\n' ); // \r\n or \n
        if (index != -1) {
            Current = Text.Slice( 0, index + 1 );
            Text = Text.Slice( index + 1 );
            return true;
        } else {
            Current = Text;
            Text = ReadOnlySpan<char>.Empty;
            return true;
        }
    }


}

I rarely employ cursors, but I just discovered one other item that can bite you here, the scope of the cursor name.

If the database CURSOR_DEFAULT is global, you will get the "cursor already exists" error if you declare a cursor in a stored procedure with a particular name (eg "cur"), and while that cursor is open you call another stored procedure which declares and opens a cursor with the same name (eg "cur"). The error will occur in the nested stored procedure when it attempts to open "cur".

Run this bit of sql to see your CURSOR_DEFAULT:

select is_local_cursor_default from sys.databases where name = '[your database name]'

If this value is "0" then how you name your nested cursor matters!

I do not have a USB serial device, but there must be a way to find the real ports using the HAL libraries directly:

====================================================================
#! /usr/bin/env bash
#
# Uses HAL to find existing serial hardware
#

for sport in $(hal-find-by-capability --capability serial) ; do
  hal-get-property --udi "${sport}" --key serial.device
done

====================================================================

The posted python-dbus code nor this sh script lists the bluetooth /dev/rfcomm* devices, so it is not the best solution.

Note that on other unix platforms, the serial ports are not named ttyS? and even in linux, some serial cards allow you to name the devices. Assuming a pattern in the serial devices names is wrong.

If you want to delete document according to a date. You can use kibana console (v.6.1.2)

POST index_name/_delete_by_query
{
      "query" : {
              "range" : {
                 "sendDate" : {
                     "lte" : "2018-03-06"
                              }
                        }
                  }
}

In VB.NET using Function,

Dim query = From order In dc.Orders
            From vendor In 
            dc.Vendors.Where(Function(v) v.Id = order.VendorId).DefaultIfEmpty()
            From status In 
            dc.Status.Where(Function(s) s.Id = order.StatusId).DefaultIfEmpty()
            Select Order = order, Vendor = vendor, Status = status 

use this code...

    dt = city.GetAllCity();//your datatable
    string attachment = "attachment; filename=city.xls";
    Response.ClearContent();
    Response.AddHeader("content-disposition", attachment);
    Response.ContentType = "application/vnd.ms-excel";
    string tab = "";
    foreach (DataColumn dc in dt.Columns)
    {
        Response.Write(tab + dc.ColumnName);
        tab = "\t";
    }
    Response.Write("\n");
    int i;
    foreach (DataRow dr in dt.Rows)
    {
        tab = "";
        for (i = 0; i < dt.Columns.Count; i++)
        {
            Response.Write(tab + dr[i].ToString());
            tab = "\t";
        }
        Response.Write("\n");
    }
    Response.End();

   };

This should work:

/^((?!PART).)*$/

If you only wanted to exclude it from the beginning of the line (I know you don't, but just FYI), you could use this:

/^(?!PART)/

Edit (by request): Why this pattern works

The (?!...) syntax is a negative lookahead, which I've always found tough to explain. Basically, it means "whatever follows this point must not match the regular expression /PART/." The site I've linked explains this far better than I can, but I'll try to break this down:

^         #Start matching from the beginning of the string.    
(?!PART)  #This position must not be followed by the string "PART".
.         #Matches any character except line breaks (it will include those in single-line mode).
$         #Match all the way until the end of the string.

The ((?!xxx).)* idiom is probably hardest to understand. As we saw, (?!PART) looks at the string ahead and says that whatever comes next can't match the subpattern /PART/. So what we're doing with ((?!xxx).)* is going through the string letter by letter and applying the rule to all of them. Each character can be anything, but if you take that character and the next few characters after it, you'd better not get the word PART.

The ^ and $ anchors are there to demand that the rule be applied to the entire string, from beginning to end. Without those anchors, any piece of the string that didn't begin with PART would be a match. Even PART itself would have matches in it, because (for example) the letter A isn't followed by the exact string PART.

Since we do have ^ and $, if PART were anywhere in the string, one of the characters would match (?=PART). and the overall match would fail. Hope that's clear enough to be helpful.

Try something like

SELECT 'rupesh''s' + 'malviya'

+ (String Concatenation)

I'm going to begin this answer with an illustration:

var colours = ['red', 'green', 'blue'];
document.getElementById('element').addEventListener('click', function() {
    // this is a reference to the element clicked on

    var that = this;

    colours.forEach(function() {
        // this is undefined
        // that is a reference to the element clicked on
    });
});

My answer originally demonstrated this with jQuery, which is only very slightly different:

$('#element').click(function(){
    // this is a reference to the element clicked on

    var that = this;

    $('.elements').each(function(){
        // this is a reference to the current element in the loop
        // that is still a reference to the element clicked on
    });
});

Because this frequently changes when you change the scope by calling a new function, you can't access the original value by using it. Aliasing it to that allows you still to access the original value of this.

Personally, I dislike the use of that as the alias. It is rarely obvious what it is referring to, especially if the functions are longer than a couple of lines. I always use a more descriptive alias. In my examples above, I'd probably use clickedEl.

you just need to use word boundary (\b) instead of ^ and $:

\bgarp\b

This worked for me:

<a onClick={this.openPopupbox} style={{cursor: 'pointer'}}>

How are you? I had the same problem while i was trying connect to MSSQL Server remotely using jdbc (dbeaver on debian).

After a while, i found out that my firewall configuration was not correctly. So maybe it could help you!

Configure the firewall to allow network traffic that is related to SQL Server and to the SQL Server Browser service.

Four exceptions must be configured in Windows Firewall to allow access to SQL Server:

A port exception for TCP Port 1433. In the New Inbound Rule Wizard dialog, use the following information to create a port exception: Select Port Select TCP and specify port 1433 Allow the connection Choose all three profiles (Domain, Private & Public) Name the rule “SQL – TCP 1433" A port exception for UDP Port 1434. Click New Rule again and use the following information to create another port exception: Select Port Select UDP and specify port 1434 Allow the connection Choose all three profiles (Domain, Private & Public) Name the rule “SQL – UDP 1434 A program exception for sqlservr.exe. Click New Rule again and use the following information to create a program exception: Select Program Click Browse to select ‘sqlservr.exe’ at this location: [C:\Program Files\Microsoft SQL Server\MSSQL11.\MSSQL\Binn\sqlservr.exe] where is the name of your SQL instance. Allow the connection Choose all three profiles (Domain, Private & Public) Name the rule SQL – sqlservr.exe A program exception for sqlbrowser.exe Click New Rule again and use the following information to create another program exception: Select Program Click Browse to select sqlbrowser.exe at this location: [C:\Program Files\Microsoft SQL Server\90\Shared\sqlbrowser.exe]. Allow the connection Choose all three profiles (Domain, Private & Public) Name the rule SQL - sqlbrowser.exe

You do not need it.

If your action has the HttpPost attribute, then you do not need to bother with setting the JsonRequestBehavior and use the overload without it. There is an overload for each method without the JsonRequestBehavior enum. Here they are:

Without JsonRequestBehavior

protected internal JsonResult Json(object data);
protected internal JsonResult Json(object data, string contentType);
protected internal virtual JsonResult Json(object data, string contentType, Encoding contentEncoding);

With JsonRequestBehavior

protected internal JsonResult Json(object data, JsonRequestBehavior behavior);
protected internal JsonResult Json(object data, string contentType, 
                                   JsonRequestBehavior behavior);
protected internal virtual JsonResult Json(object data, string contentType, 
    Encoding contentEncoding, JsonRequestBehavior behavior);

Split() Variation

I just want to add this variation for reference. Urls are often strings and so it's simpler to use the Split() method than Uri.GetLeftPart(). And Split() can also be made to work with relative, empty, and null values whereas Uri throws an exception. Additionally, Urls may also contain a hash such as /report.pdf#page=10 (which opens the pdf at a specific page).

The following method deals with all of these types of Urls:

   var path = (url ?? "").Split('?', '#')[0];

Example Output:

• null ---> empty
• empty ---> empty
• http://domain/page.html ---> http://domain/page.html
• http://domain/page.html?q=100 ---> http://domain/page.html
• http://domain/page.html?q=100#page=2 ---> http://domain/page.html

• http://domain/page.html#page=2 ---> http://domain/page.html

• page.html ---> page.html

• page.html?q=100 ---> page.html
• page.html?q=100#page=2 ---> page.html
• page.html#hash ---> page.html

If you use it SQLServer 2008R2 you need to set Types of data to script field.

To see how that can go wrong, print console.log at the end of the method.

Things that can go wrong in general:

• Arbitrary order.
• printFiles can finish running before printing files.
• Poor performance.

These are not always wrong but frequently are in standard use cases.

Generally, using forEach will result in all but the last. It'll call each function without awaiting for the function meaning it tells all of the functions to start then finishes without waiting for the functions to finish.

import fs from 'fs-promise'

async function printFiles () {
  const files = (await getFilePaths()).map(file => fs.readFile(file, 'utf8'))

  for(const file of files)
    console.log(await file)
}

printFiles()

This is an example in native JS that will preserve order, prevent the function from returning prematurely and in theory retain optimal performance.

This will:

• Initiate all of the file reads to happen in parallel.
• Preserve the order via the use of map to map file names to promises to wait for.
• Wait for each promise in the order defined by the array.

With this solution the first file will be shown as soon as it is available without having to wait for the others to be available first.

It will also be loading all files at the same time rather than having to wait for the first to finish before the second file read can be started.

The only draw back of this and the original version is that if multiple reads are started at once then it's more difficult to handle errors on account of having more errors that can happen at a time.

With versions that read a file at a time then then will stop on a failure without wasting time trying to read any more files. Even with an elaborate cancellation system it can be hard to avoid it failing on the first file but reading most of the other files already as well.

Performance is not always predictable. While many systems will be faster with parallel file reads some will prefer sequential. Some are dynamic and may shift under load, optimisations that offer latency do not always yield good throughput under heavy contention.

There is also no error handling in that example. If something requires them to either all be successfully shown or not at all it won't do that.

In depth experimentation is recommended with console.log at each stage and fake file read solutions (random delay instead). Although many solutions appear to do the same in simple cases all have subtle differences that take some extra scrutiny to squeeze out.

Use this mock to help tell the difference between solutions:

(async () => {
  const start = +new Date();
  const mock = () => {
    return {
      fs: {readFile: file => new Promise((resolve, reject) => {
        // Instead of this just make three files and try each timing arrangement.
        // IE, all same, [100, 200, 300], [300, 200, 100], [100, 300, 200], etc.
        const time = Math.round(100 + Math.random() * 4900);
        console.log(`Read of ${file} started at ${new Date() - start} and will take ${time}ms.`)
        setTimeout(() => {
          // Bonus material here if random reject instead.
          console.log(`Read of ${file} finished, resolving promise at ${new Date() - start}.`);
          resolve(file);
        }, time);
      })},
      console: {log: file => console.log(`Console Log of ${file} finished at ${new Date() - start}.`)},
      getFilePaths: () => ['A', 'B', 'C', 'D', 'E']
    };
  };

  const printFiles = (({fs, console, getFilePaths}) => {
    return async function() {
      const files = (await getFilePaths()).map(file => fs.readFile(file, 'utf8'));

      for(const file of files)
        console.log(await file);
    };
  })(mock());

  console.log(`Running at ${new Date() - start}`);
  await printFiles();
  console.log(`Finished running at ${new Date() - start}`);
})();

There is a pretty good list at linuxappfinder.com.

My personal preference for LaTeX on Linux has been the KDE-based editor Kile.

I do no expect that multiple div's is a good solution.

I also think you can replace .visible-sm-block with .hidden-xs-down and .hidden-md-up (or .hidden-sm-down and .hidden-lg-up to act on the same media queries).

hidden-sm-up compiles into:

.visible-sm-block {
  display: none !important;
}
@media (min-width: 768px) and (max-width: 991px) {
  .visible-sm-block {
    display: block !important;
  }
}

.hidden-sm-down and .hidden-lg-up compiles into:

@media (max-width: 768px) {
  .hidden-xs-down {
    display: none !important;
  }
}
@media (min-width: 991px) {
  .hidden-lg-up {
    display: none !important;
  }
}

Both situation should act the same.

You situation become different when you try to replace .visible-sm-block and .visible-lg-block. Bootstrap v4 docs tell you:

These classes don’t attempt to accommodate less common cases where an element’s visibility can’t be expressed as a single contiguous range of viewport breakpoint sizes; you will instead need to use custom CSS in such cases.

.visible-sm-and-lg {
  display: none !important;
}
@media (min-width: 768px) and (max-width: 991px) {
  .visible-sm-and-lg {
    display: block !important;
  }
}
@media (min-width: 1200px) {
  .visible-sm-and-lg {
    display: block !important;
  }
}

Got the issue for months, and finally discovered that when we disable DNSSEC on our api domain, everything was ok :simple_smile:

Found this works in Safari. SVG only colors in with background-color where an element's bounding box covers. So, give it a border (stroke) with a zero pixel boundary. It fills in the whole thing for you with your background-color.

<svg style='stroke-width: 0px; background-color: blue;'> </svg>

a[len(a):] - This gets you the length of a to the end. It selects a range. If you reverse a[:len(a)] it will get you the beginning to whatever is len(a).

This is caused when your request response is not received in given time(by timeout request module option).

Basically to catch that error first, you need to register a handler on error, so the unhandled error won't be thrown anymore: out.on('error', function (err) { /* handle errors here */ }). Some more explanation here.

In the handler you can check if the error is ETIMEDOUT and apply your own logic: if (err.message.code === 'ETIMEDOUT') { /* apply logic */ }.

If you want to request for the file again, I suggest using node-retry or node-backoff modules. It makes things much simpler.

If you want to wait longer, you can set timeout option of request yourself. You can set it to 0 for no timeout.

I'd rather use static widths and if you'd like your page to resize depending on screen size, you can have a look at media queries.

Or, you can set a min-width on elements like header, navigation, content etc.

nl2br() worked for me, but I needed to wrap the variable with double quotes:

This works:

$description = nl2br("$description");

This doesn't work:

$description = nl2br($description);

You need to create an object since printInformation() is non-static. Try:

int main() {

MyClass o;
o.printInformation();

fgetc( stdin );
return(0);

}

I've a solution for bash purists.

The function 'define' helps us to assign a multiline value to a variable. This one takes one positional parameter: the variable name to assign the value.

In the heredoc, optionally there're parameter expansions too!

Is there a way to ignore existing errors in project. Something similar what eclipse allows in case of java projects.

In my case the errors exist in jni directory. The errors are shown even though ndk-buid succeeds. So all i want to do is to ignore the errors reported by eclipse.

If the errors are indeed errors then i should get unresolved symbols during ndk-build.

I have ensured standard android includes are there in include path.

Also my project is of type android/c/c++.

I have two builders associated with the project 1. statndard android builder 2. custom ndk builder that ive explicitly created.

document.querySelectorAll("[data-foo]")

will get you all elements with that attribute.

document.querySelectorAll("[data-foo='1']")

will only get you ones with a value of 1.

    System.setErr(save_err);
}

A general solution to convert from byte array to string when you don't know the encoding:

static string BytesToStringConverted(byte[] bytes)
{
    using (var stream = new MemoryStream(bytes))
    {
        using (var streamReader = new StreamReader(stream))
        {
            return streamReader.ReadToEnd();
        }
    }
}

This should give you all the details of the existing locks.

DECLARE @tblVariable TABLE(SPID INT, Status VARCHAR(200), [Login] VARCHAR(200), HostName VARCHAR(200), 
    BlkBy VARCHAR(200), DBName VARCHAR(200), Command VARCHAR(200), CPUTime INT, 
    DiskIO INT, LastBatch VARCHAR(200), ProgramName VARCHAR(200), _SPID INT, 
    RequestID INT)

INSERT INTO @tblVariable
EXEC Master.dbo.sp_who2

SELECT v.*, t.TEXT 
FROM @tblVariable v
INNER JOIN sys.sysprocesses sp ON sp.spid = v.SPID
CROSS APPLY sys.dm_exec_sql_text(sp.sql_handle) AS t
ORDER BY BlkBy DESC, CPUTime DESC

You can then kill, with caution, the SPID that blocks your table.

kill 104 -- Your SPID

Factory classes are more heavyweight, but give you certain advantages. In cases when you need to build your objects from multiple, raw data sources they allow you to encapsulate only the building logic (and maybe the aggregation of the data) in one place. There it can be tested in abstract without being concerned with the object interface.

I have found this a useful pattern, particularly where I am unable to replace and inadequate ORM and want to efficiently instantiate many objects from DB table joins or stored procedures.

In python there is no difference between modules and scripts; You can execute both scripts and modules. The file must be on the pythonpath AFAIK because python must be able to find the file in question. If python is executed from a directory, then the directory is automatically added to the pythonpath.

Refer to What is the best way to call a Python script from another Python script? for more information about modules vs scripts

There is also a builtin function execfile(filename) that will do what you want

You will have to put:

X = input("give starting number") 
X = int(X)
Y = input("give ending number") 
Y = int(Y)

Manually add it when you build the query:

SELECT 'Site1' AS SiteName, t1.column, t1.column2
FROM t1

UNION ALL
SELECT 'Site2' AS SiteName, t2.column, t2.column2
FROM t2

UNION ALL
...

EXAMPLE:

DECLARE @t1 TABLE (column1 int, column2 nvarchar(1))
DECLARE @t2 TABLE (column1 int, column2 nvarchar(1))

INSERT INTO @t1
SELECT 1, 'a'
UNION SELECT 2, 'b'

INSERT INTO @t2
SELECT 3, 'c'
UNION SELECT 4, 'd'


SELECT 'Site1' AS SiteName, t1.column1, t1.column2
FROM @t1 t1

UNION ALL
SELECT 'Site2' AS SiteName, t2.column1, t2.column2
FROM @t2 t2

RESULT:

SiteName  column1  column2
Site1       1      a
Site1       2      b
Site2       3      c
Site2       4      d

$query = "INSERT INTO myTable VALUES (NULL,'Fname', 'Lname', 'Website')";

Just leaving the value of the AI primary key NULL will assign an auto incremented value.

my answer is for windows 10 users only as I have tried the following on windows 10. Extending some of the answers above I suggest this : If you are using anaconda then you can avoid everything and simply install anaconda-navigator using the command

conda install -c anaconda anaconda-navigator

Then you can launch the navigator from command prompt using the command

anaconda-navigator

On running this command you get a simple gui where you can create an virtual environment, create the environment with python=3.5.2 and install module tensorflow-gpu or tensorflow by searching the module in the search box using gui, it will also take care of installing correct cuda files for you. Using anaconda navigator is the simplest solution.

If you are not using anaconda then take care about the following

tensorflow-gpu 1.3 requires python 3.5.2, cuda development kit 8.0 and cudaDNN 6.0, hence when installing make sure you run the command

pip install tensorflow-gpu==1.3

tensorflow-gpu 1.2.1 or less requires python 3.5.2, cuda development kit 8.0 and cudaDNN 5.1 hence when installing make sure you run the command

pip install tensorflow-gpu==1.2.1

Below are the steps you need to follow for both of the above processes Setting up you path variables You must have the following system variables

CUDA_HOME = "C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0"
CUDA_PATH = "C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0"
CUDA_PATH_V8.0 = "C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0"

You PATHTEXT must include ".DLL" along with other extensions

".COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC;.PY;.DLL"

Also Add the following to you path

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\lib\x64
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\extras\CUPTI\libx64;
C:\Windows\SysWOW64;
C:\Windows\System32

"How do I write ruby" is a little beyond the scope of SO.

But to turn these ruby scripts into executable scripts, put this as the first line of your ruby script:

#!/path/to/ruby

Then make the file executable:

chmod a+x myscript.rb

and away you go.

You are not allowed to have a CNAME record for the domain, as the CNAME is an aliasing feature that covers all data types (regardless of whether the client looks for MX, NS or SOA records). CNAMEs also always refer to a new name, not an ip-address, so there are actually two errors in the single line

@                        IN CNAME   88.198.38.XXX

Changing that CNAME to an A record should make it work, provided the ip-address you use is the correct one for your Heroku app.

The only correct way in DNS to make a simple domain.com name work in the browser, is to point the domain to an IP-adress with an A record.

In PHP, passing by reference (&) is ... controversial. I recommend not using it unless you know why you need it and test the results.

I would recommend doing the following:

foreach ($fields as $key => $field) {
    if ($field['required'] && strlen($_POST[$field['name']]) <= 0) {
        $fields[$key]['value'] = "Some error";
    }
}

So basically use $field when you need the values, and $fields[$key] when you need to change the data.

For Upgradation php in Xampp you can follow this steps, Else you can skip these 4 steps and direct install MAMP (for windows as well) from site and here is the direct download link

Step 1: Make backups Before starting, make sure to backup any settings, custom modules and most importantly the htdocs directory, which contains your scripts and page resources. This directory is normally located atC:\xampp\htdocs\

Step 2: Preparation

Download PHP 5.3.0rc2. I use the VC6 build in order to minimise any potential compatibility issues. It is also recommended that you download the latest Windows version of XAMPP. While this is an upgrade guide that shouldwork with previous versions of XAMPP, it is recommended that a fresh copy of the core files is used. Stop any instances of the Apache service that might be running.

Step 3: The upgrade This guide will assume your XAMPP directory is C:\xampp\

Extract the XAMPP archive to a directory of your choosing, I would recommend using the default C:\xampp\ Extract the contents of the PHP archive to C:\xampp\php\, overwriting the contents of this directory with the new files. Open the file C:\xampp\apache\conf\extra\httpd-xampp.conf and ensure the following lines are present in this order:

LoadFile "/xampp/php/php5ts.dll"
LoadModule php5_module "/xampp/apache/bin/php5apache2_2.dll"

Replace C:\xampp\php\php.ini with C:\xampp\php\php.ini-dist
Uncomment the lines:

;extension=php_mbstring.dll
;extension=php_pdo_sqlite.dll

Replace the line

magic_quotes_gpc = On

with

magic_quotes_gpc = Off

Copy all files in the C:\xampp\php\ to C:\xampp\apache\bin\ (do not copy the subdirectories or their contents).

After following the above steps, restart your Apache service (this can be done using C:\xampp\xampp-control.exe or manually through the control panel/command prompt). Your PHPinfo should indicate that the upgrade has been successful. I will update this post if I discover any problems from using this method, or a cleaner (automated) means of performing the upgrade.

here is how you can perform simply, make a drawable resource file in drawable.xml. Say round_button.xml and then paste the following code.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item>
       <shape
           android:shape="oval">

           <solid
               android:color="@color/button_start_gradient_color"/>
       </shape>
    </item>
    <item
        android:drawable="@drawable/microphone"/>
</layer-list>

Note:- use your own color and drawable resource as i have used @drawable/microphone

Following is the result [1]: https://i.stack.imgur.com/QyhdJ.png

import java.io.IOException;
import java.lang.ProcessBuilder;

public class handlingexe {
    public static void main(String[] args) throws IOException {
        ProcessBuilder p = new ProcessBuilder();
        System.out.println("Started EXE");
        p.command("C:\\Users\\AppData\\Local\\Google\\Chrome\\Application\\chrome.exe");   

        p.start();
        System.out.println("Started EXE"); 
    }
}

Unfortunately, Java doesn't provide an easy way to list classes in the "native" JRE. That leaves you with a couple of options: (a) for any given JAR file, you can list the entries inside that JAR file, find the .class files, and then determine which Java class each .class file represents; or (b) you can use a library that does this for you.

Option (a): Scanning JAR files manually

In this option, we'll fill classNames with the list of all Java classes contained inside a jar file at /path/to/jar/file.jar.

List<String> classNames = new ArrayList<String>();
ZipInputStream zip = new ZipInputStream(new FileInputStream("/path/to/jar/file.jar"));
for (ZipEntry entry = zip.getNextEntry(); entry != null; entry = zip.getNextEntry()) {
    if (!entry.isDirectory() && entry.getName().endsWith(".class")) {
        // This ZipEntry represents a class. Now, what class does it represent?
        String className = entry.getName().replace('/', '.'); // including ".class"
        classNames.add(className.substring(0, className.length() - ".class".length()));
    }
}

Option (b): Using specialized reflections libraries

Guava

Guava has had ClassPath since at least 14.0, which I have used and liked. One nice thing about ClassPath is that it doesn't load the classes it finds, which is important when you're scanning for a large number of classes.

ClassPath cp=ClassPath.from(Thread.currentThread().getContextClassLoader());
for(ClassPath.ClassInfo info : cp.getTopLevelClassesRecurusive("my.package.name")) {
    // Do stuff with classes here...
}

Reflections

I haven't personally used the Reflections library, but it seems well-liked. Some great examples are provided on the website like this quick way to load all the classes in a package provided by any JAR file, which may also be useful for your application.

Reflections reflections = new Reflections("my.project.prefix");

Set<Class<? extends SomeType>> subTypes = reflections.getSubTypesOf(SomeType.class);

Set<Class<?>> annotated = reflections.getTypesAnnotatedWith(SomeAnnotation.class);

For anyone looking for a scalable solution: I wrote a small helper utility in SASS to generate responsive proportional rectangles for different breakpoints. Take a look at SASS Proportions

Hope it helps anybody!

As of Laravel 5.2+, you can fetch it directly with $request->input('item') as well.

Retrieving JSON Input Values

When sending JSON requests to your application, you may access the JSON data via the input method as long as the Content-Type header of the request is properly set to application/json. You may even use "dot" syntax to dig deeper into JSON arrays:

$name = $request->input('user.name');

https://laravel.com/docs/5.2/requests

As noted above, the content-type header must be set to application/json so the jQuery ajax call would need to include contentType: "application/json",

$.ajax({
    type: "POST",
    url: "/people",
    data: '[{ "name": "John", "location": "Boston" }, { "name": "Dave", "location": "Lancaster" }]',
    dataType: "json",
    contentType: "application/json",
    success:function(data) {
        $('#save_message').html(data.message);
    } 
});

By fixing the AJAX call, $request->all() should work.

I had the same problem, what helped we was turning of my anti virus protection for like 10 minutes while node installed and it worked like a charm.

Please use this.. it is simplest.

\p{Punct} Punctuation: One of !"#$%&'()*+,-./:;<=>?@[]^_`{|}~

https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html

    StringBuilder builder = new StringBuilder(checkstring);
    String regex = "\\p{Punct}"; //Special character : `~!@#$%^&*()-_+=\|}{]["';:/?.,><
    //change your all special characters to "" 
    Pattern  pattern = Pattern.compile(regex);
    Matcher matcher = pattern.matcher(builder.toString());
    checkstring=matcher.replaceAll("");

bottomline: if you are working offline with selects on large chunks of data, MyISAM will probably give you better (much better) speeds.

there are some situations when MyISAM is infinitely more efficient than InnoDB: when manipulating large data dumps offline (because of table lock).

example: I was converting a csv file (15M records) from NOAA which uses VARCHAR fields as keys. InnoDB was taking forever, even with large chunks of memory available.

this an example of the csv (first and third fields are keys).

USC00178998,20130101,TMAX,-22,,,7,0700
USC00178998,20130101,TMIN,-117,,,7,0700
USC00178998,20130101,TOBS,-28,,,7,0700
USC00178998,20130101,PRCP,0,T,,7,0700
USC00178998,20130101,SNOW,0,T,,7,

since what i need to do is run a batch offline update of observed weather phenomena, i use MyISAM table for receiving data and run JOINS on the keys so that i can clean the incoming file and replace VARCHAR fields with INT keys (which are related to external tables where the original VARCHAR values are stored).

A very useful lib for custom progress bar in android.

In your layout file

<com.lylc.widget.circularprogressbar.example.CircularProgressBar
android:id="@+id/mycustom_progressbar"
.
.
.
 />

and Java file

CircularProgressBar progressBar = (CircularProgressBar) findViewById(R.id.mycustom_progressbar);
progressBar.setTitle("Circular Progress Bar");

I think you add click event five times. Try to count how many times you do this.

console.log('add click event')
$(".addproduct").click(function(){ });

You can use a Web Method and Ajax:

<script type="text/javascript">             //Default.aspx
   function DeleteKartItems() {     
         $.ajax({
         type: "POST",
         url: 'Default.aspx/DeleteItem',
         data: "",
         contentType: "application/json; charset=utf-8",
         dataType: "json",
         success: function (msg) {
             $("#divResult").html("success");
         },
         error: function (e) {
             $("#divResult").html("Something Wrong.");
         }
     });
   }
</script>

[WebMethod]                                 //Default.aspx.cs
public static void DeleteItem()
{
    //Your Logic
}

Remove the extension altogether and then double-click it. Most system shell scripts are like this. As long as it has a shebang it will work.

Try out using getDate feature of datepicker.

$.datepicker.formatDate('yy-mm-dd',new Date(pField.datepicker("getDate")));

Qt provides the simplest API

const char *qPrintable(const QString &str)
const char *qUtf8Printable(const QString &str)

If you want non-const data pointer use

str.toLocal8Bit().data()
str.toUtf8().data()

In Ruby IO module documentation, I suppose.

Problem: you have 64-bit Python, and a 32-bit installer. This will cause problems for extension modules.

The reasons why the installer doesn't finds Python is the transparent 32-bit emulation from Windows 7. 64-bit and 32-bit programs will write to different parts of the Windows registry.

64-bit: HKLM|HKCU\SOFTWARE\

32-bit: HKLM|HKCU\SOFTWARE\wow6432node\.

This means that the 64-bit Python installer writes to HKLM\SOFTWARE\Python, but the 32-bit setuptools installer looks at HKLM\SOFTWARE\wow6432node\Python (this is handled by windows automatically, programs don't notice). This is expected behavior and not a bug.

Usually, you have these choices:

• the "clean" way: use 32-bit Python if you have to use 32-bit modules or extensions
• the other "clean" way: only use 64-bit installers when using 64-bit Python (see below)
• what the answer above suggests: copy HKLM\SOFTWARE\Python to HKLM\SOFTWARE\wow6432node\Python, but this will cause problems with binary distributions, as 64-bit Python can't load 32-bit compiled modules (do NOT do this!)
• install pure Python modules with setuptools instead of the distutils installer (easy_install or pip)

For setuptools itself, for example, you can't use a 32-bit installer for 64-bit Python as it includes binary files. But there's a 64-bit installer at http://www.lfd.uci.edu/~gohlke/pythonlibs/ (has many installers for other modules too). Nowadays, many packages on PyPi have binary distributions, so you can install them via pip.

Recursively find all controls matching the specified predicate (do not include root Control):

    public static IEnumerable<Control> FindControlsRecursive(this Control control, Func<Control, bool> predicate)
    {
        var results = new List<Control>();

        foreach (Control child in control.Controls)
        {
            if (predicate(child))
            {
                results.Add(child);
            }
            results.AddRange(child.FindControlsRecursive(predicate));
        }

        return results;
    }

Usage:

myControl.FindControlsRecursive(c => c.ID == "findThisID");

Second approach is object initializer in C#

Object initializers let you assign values to any accessible fields or properties of an object at creation time without having to explicitly invoke a constructor.

The first approach

var albumData = new Album("Albumius", "Artistus", 2013);

explicitly calls the constructor, whereas in second approach constructor call is implicit. With object initializer you can leave out some properties as well. Like:

 var albumData = new Album
        {
            Name = "Albumius",
        };

Object initializer would translate into something like:

var albumData; 
var temp = new Album();
temp.Name = "Albumius";
temp.Artist = "Artistus";
temp.Year = 2013;
albumData = temp;

Why it uses a temporary object (in debug mode) is answered here by Jon Skeet.

As far as advantages for both approaches are concerned, IMO, object initializer would be easier to use specially if you don't want to initialize all the fields. As far as performance difference is concerned, I don't think there would any since object initializer calls the parameter less constructor and then assign the properties. Even if there is going to be performance difference it should be negligible.

Go to res package and open color.xml. Set color primary to #00000000.

Your line:

img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.

Try

cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

The error is coming from $userRecord->email. You need to use the ->get() or ->first() methods when calling from the database otherwise you're only getting the Eloquent\Builder object rather than an Eloquent\Collection

The ->first() method is pretty self-explanatory, it will return the first row found. ->get() returns all the rows found

$userRecord = Model::where('email', '=', $email)->where('password', '=', $password)->get();
echo "First name: " . $userRecord->email;

Simplest way is to add a target tag.

<a href="http://www.starfall.com/" target="Starfall">Starfall</a>

Use a different value for the target attribute for each link if you want them to open in different tabs, the same value for the target attribute if you want them to replace the other ones.

I am facing the same issue on Xcode 7.3 and my device version is iOS 10.

This error is shown when your Xcode is old and the related device you are using is updated to latest version. First of all, install the latest Xcode version.

We can solve this issue by following the below steps:-

• Open Finder select Applications
• Right click on Xcode 8, select "Show Package Contents", "Contents", "Developer", "Platforms", "iPhoneOS.Platform", "Device Support"
• Copy the 10.0 folder (or above for later version).
• Back in Finder select Applications again
• Right click on Xcode 7.3, select "Show Package Contents", "Contents", "Developer", "Platforms", "iPhoneOS.Platform", "Device Support"
• Paste the 10.0 folder

If everything worked properly, your Xcode has a new developer disk image. Close the finder now, and quit your Xcode. Open your Xcode and the error will be gone. Now you can connect your latest device to old Xcode versions.

Thanks

As per the javadoc of NotEmpty, Integer is not a valid type for it to check. It's for Strings and collections. If you just want to make sure an Integer has some value, javax.validation.constraints.NotNull is all you need.

public @interface NotEmpty

Asserts that the annotated string, collection, map or array is not null or empty.

I had a similar error..This might be due to two reasons. a) If you have used variables, re-evaluate the expressions in which variables are used and make sure the expression is evaluated without errors. b) If you are deleting the excel sheet and creating excel sheet on the fly in your package.

When on Ubuntu 18.04 using Python3.6 I have solved the problem doing both:

with open(filename, encoding="utf-8") as lines:

and if you are running the tool as command line:

export LC_ALL=C.UTF-8

Note that if you are in Python2.7 you have do to handle this differently. First you have to set the default encoding:

import sys
reload(sys)
sys.setdefaultencoding('utf-8')

and then to load the file you must use io.open to set the encoding:

import io
with io.open(filename, 'r', encoding='utf-8') as lines:

You still need to export the env

export LC_ALL=C.UTF-8

It should be noted that starting from C++17 filesystem interface is part of the standard library. This means that one can have following to create directories:

#include <filesystem>

std::filesystem::create_directories("/a/b/c/d")

More info here: https://en.cppreference.com/w/cpp/filesystem/create_directory

Additionally, with gcc, one needs to "-std=c++17" to CFLAGS. And "-lstdc++fs" to LDLIBS. The latter potentially is not going to be required in the future.

Cache: This is a place acquired by kernel on physical RAM to store pages in caches. Now we need some sort of index to get the address of pages from caches. Here we need the buffer for page caches which keeps metadata of page cache.

it's file:///android_asset/... not file:///android_assets/... notice the plural of assets is wrong even if your file name is assets

F# is not yet-another-programming-language if you are comparing it to C#, C++, VB. C#, C, VB are all imperative or procedural programming languages. F# is a functional programming language.

Two main benefits of functional programming languages (compared to imperative languages) are 1. that they don't have side-effects. This makes mathematical reasoning about properties of your program a lot easier. 2. that functions are first class citizens. You can pass functions as parameters to another functions just as easily as you can other values.

Both imperative and functional programming languages have their uses. Although I have not done any serious work in F# yet, we are currently implementing a scheduling component in one of our products based on C# and are going to do an experiment by coding the same scheduler in F# as well to see if the correctness of the implementation can be validated more easily than with the C# equivalent.

Add checked to both of your radio button. And then show/hide your desired one on document ready.

<div class="form-group">
    <div class="mt-radio-inline" style="padding-left:15px;">
        <label class="mt-radio mt-radio-outline">
            Full Edition
            <input type="radio" value="@((int)SelectEditionTypeEnum.FullEdition)" asp-for="SelectEditionType" checked>
            <span></span>
        </label>
        <label class="mt-radio mt-radio-outline">
            Select Modules
            <input type="radio" value="@((int)SelectEditionTypeEnum.CustomEdition)" asp-for="SelectEditionType" checked>
            <span></span>
        </label>
    </div>

For me the issue was caused by com.google.android.exoplayer conflicting with com.facebook.android:audience-network-sdk.

I fixed the problem by excluding the exoplayer library from the audience-network-sdk :

compile ('com.facebook.android:audience-network-sdk:4.24.0') {
    exclude group: 'com.google.android.exoplayer'
}

while (<>) {
print;
}

will read either from a file specified on the command line or from stdin if no file is given

If you are required this loop construction in command line, then you may use -n option:

$ perl -ne 'print;'

Here you just put code between {} from first example into '' in second

A simpler way would be to create a link called cudart64_101.dll to point to cudart64_102.dll. This is not very orthodox but since TensorFlow is looking for cudart64_101.dll exported symbols and the nvidia folks are not amateurs, they would most likely not remove symbols from 101 to 102. It works, based on this assumption (mileage may vary).

Suppose you have a tree like this:

dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]

First, checkout a temp branch:

git checkout -b temp

On temp branch, reset --hard to a commit that you want to change its message (for example, that commit is 946992):

git reset --hard 946992

Use amend to change the message:

git commit --amend -m "<new_message>"

After that the tree will look like this:

dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]
           \
            b886a0 [temp]

Then, cherry-pick all the commit that is ahead of 946992 from master to temp and commit them, use amend if you want to change their messages as well:

git cherry-pick 9143a9
git commit --amend -m "<new_message>
...
git cherry-pick 5a6057
git commit --amend -m "<new_message>

The tree now looks like this:

dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]
               \
                b886a0 - 41ab2c - 6c2a3s - 7c88c9 [temp]

Now force push the temp branch to remote:

git push --force origin temp:master

The final step, delete branch master on local, git fetch origin to pull branch master from the server, then switch to branch master and delete branch temp.

Now both your local and remote will have all the messages updated.

I agree with using frameworks for things like this, just because its easier. I hacked this up real quick, just fades an image out and then switches, also will not work in older versions of IE. But as you can see the code for the actual fade is much longer than the JQuery implementation posted by KARASZI István.

function changeImage() {
    var img = document.getElementById("img");
    img.src = images[x];
    x++;        
    if(x >= images.length) {
        x = 0;
    } 
    fadeImg(img, 100, true);
    setTimeout("changeImage()", 30000);
}

function fadeImg(el, val, fade) {
    if(fade === true) {
        val--;
    } else {
        val ++;
    }       
    if(val > 0 && val < 100) {
        el.style.opacity = val / 100;
        setTimeout(function(){ fadeImg(el, val, fade); }, 10);
    }
}

var images = [], x = 0;
images[0] = "image1.jpg";
images[1] = "image2.jpg";
images[2] = "image3.jpg";
setTimeout("changeImage()", 30000);

I think it would make more sense to use "Find" function in Excel instead of For Each loop. It works much much faster and it's designed for such actions. Try this:

 Sub FindSomeCells(strSearchQuery As String)   

    Set SearchRange = Worksheets("Sheet1").Range("A1:A100")
    FindWhat = strSearchQuery
    Set FoundCells = FindAll(SearchRange:=SearchRange, _
                            FindWhat:=FindWhat, _
                            LookIn:=xlValues, _
                            LookAt:=xlWhole, _
                            SearchOrder:=xlByColumns, _
                            MatchCase:=False, _
                            BeginsWith:=vbNullString, _
                            EndsWith:=vbNullString, _
                            BeginEndCompare:=vbTextCompare)
    If FoundCells Is Nothing Then
        Debug.Print "Value Not Found"
    Else
        For Each FoundCell In FoundCells
            FoundCell.Interior.Color = XlRgbColor.rgbLightGreen
        Next FoundCell
    End If

End Sub

That subroutine searches for some string and returns a collections of cells fullfilling your search criteria. Then you can do whatever you want with the cells in that collection. Forgot to add the FindAll function definition:

Function FindAll(SearchRange As Range, _
                FindWhat As Variant, _
               Optional LookIn As XlFindLookIn = xlValues, _
                Optional LookAt As XlLookAt = xlWhole, _
                Optional SearchOrder As XlSearchOrder = xlByRows, _
                Optional MatchCase As Boolean = False, _
                Optional BeginsWith As String = vbNullString, _
                Optional EndsWith As String = vbNullString, _
                Optional BeginEndCompare As VbCompareMethod = vbTextCompare) As Range
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' FindAll
' This searches the range specified by SearchRange and returns a Range object
' that contains all the cells in which FindWhat was found. The search parameters to
' this function have the same meaning and effect as they do with the
' Range.Find method. If the value was not found, the function return Nothing. If
' BeginsWith is not an empty string, only those cells that begin with BeginWith
' are included in the result. If EndsWith is not an empty string, only those cells
' that end with EndsWith are included in the result. Note that if a cell contains
' a single word that matches either BeginsWith or EndsWith, it is included in the
' result.  If BeginsWith or EndsWith is not an empty string, the LookAt parameter
' is automatically changed to xlPart. The tests for BeginsWith and EndsWith may be
' case-sensitive by setting BeginEndCompare to vbBinaryCompare. For case-insensitive
' comparisons, set BeginEndCompare to vbTextCompare. If this parameter is omitted,
' it defaults to vbTextCompare. The comparisons for BeginsWith and EndsWith are
' in an OR relationship. That is, if both BeginsWith and EndsWith are provided,
' a match if found if the text begins with BeginsWith OR the text ends with EndsWith.

Others have pointed out that INNER JOIN helps human readability, and that's a top priority, I agree.
Let me try to explain why the join syntax is more readable.

A basic SELECT query is this:

SELECT stuff
FROM tables
WHERE conditions

The SELECT clause tells us what we're getting back; the FROM clause tells us where we're getting it from, and the WHERE clause tells us which ones we're getting.

JOIN is a statement about the tables, how they are bound together (conceptually, actually, into a single table).

Any query elements that control the tables - where we're getting stuff from - semantically belong to the FROM clause (and of course, that's where JOIN elements go). Putting joining-elements into the WHERE clause conflates the which and the where-from, that's why the JOIN syntax is preferred.

You can calculate a running mean with:

import numpy as np

def runningMean(x, N):
    y = np.zeros((len(x),))
    for ctr in range(len(x)):
         y[ctr] = np.sum(x[ctr:(ctr+N)])
    return y/N

But it's slow.

Fortunately, numpy includes a convolve function which we can use to speed things up. The running mean is equivalent to convolving x with a vector that is N long, with all members equal to 1/N. The numpy implementation of convolve includes the starting transient, so you have to remove the first N-1 points:

def runningMeanFast(x, N):
    return np.convolve(x, np.ones((N,))/N)[(N-1):]

On my machine, the fast version is 20-30 times faster, depending on the length of the input vector and size of the averaging window.

Note that convolve does include a 'same' mode which seems like it should address the starting transient issue, but it splits it between the beginning and end.

Edit - This answer is a solution, but a much simpler and proper approach would be setting the tabindex attribute on the canvas element (as suggested by hobberwickey).

You can't focus a canvas element. A simple work around this, would be to make your "own" focus.

var lastDownTarget, canvas;
window.onload = function() {
    canvas = document.getElementById('canvas');

    document.addEventListener('mousedown', function(event) {
        lastDownTarget = event.target;
        alert('mousedown');
    }, false);

    document.addEventListener('keydown', function(event) {
        if(lastDownTarget == canvas) {
            alert('keydown');
        }
    }, false);
}

JSFIDDLE

With modern Git (1.8.3.4 in my case) and not using branches you can do:

$ git rev-list --count HEAD
68

I made it that way:

if I have:

var jsonArg1 = new Object();
    jsonArg1.name = 'calc this';
    jsonArg1.value = 3.1415;
var jsonArg2 = new Object();
    jsonArg2.name = 'calc this again';
    jsonArg2.value = 2.73;

var pluginArrayArg = new Array();
    pluginArrayArg.push(jsonArg1);
    pluginArrayArg.push(jsonArg2);

to convert pluginArrayArg (which is pure javascript array) into JSON array:

var jsonArray = JSON.parse(JSON.stringify(pluginArrayArg))

Use something like this:

page1.php

<?php
session_start();
$_SESSION['myValue']=3; // You can set the value however you like.
?>

Any other PHP page:

<?php
session_start();
echo $_SESSION['myValue'];
?>

A few notes to keep in mind though: You need to call session_start() BEFORE any output, HTML, echos - even whitespace.

You can keep changing the value in the session - but it will only be able to be used after the first page - meaning if you set it in page 1, you will not be able to use it until you get to another page or refresh the page.

The setting of the variable itself can be done in one of a number of ways:

$_SESSION['myValue']=1;
$_SESSION['myValue']=$var;
$_SESSION['myValue']=$_GET['YourFormElement'];

And if you want to check if the variable is set before getting a potential error, use something like this:

if(!empty($_SESSION['myValue'])
{
    echo $_SESSION['myValue'];
}
else
{
    echo "Session not set yet.";
}

If linked server name is IP address following code is true:

select * from [1.2.3.4,1433\MSSQLSERVER].test.dbo.Table1

It's just, note [] around IP address section.

    this.toolStrip1 = new System.Windows.Forms.ToolStrip();
    this.toolStrip1.Location = new System.Drawing.Point(0, 0);
    this.toolStrip1.Name = "toolStrip1";
    this.toolStrip1.Size = new System.Drawing.Size(444, 25);
    this.toolStrip1.TabIndex = 0;
    this.toolStrip1.Text = "toolStrip1";
    object O = global::WindowsFormsApplication1.Properties.Resources.ResourceManager.GetObject("best_robust_ghost");

    ToolStripButton btn = new ToolStripButton("m1");
    btn.DisplayStyle = ToolStripItemDisplayStyle.Image;
    btn.Image = (Image)O;
    this.toolStrip1.Items.Add(btn);

    this.Controls.Add(this.toolStrip1);

This week number thing has been a real pain in the a**. Most of scripts around the net didn't work for me. They worked most of time but all of them broke in some point, especially when year changed and last week of the year was suddenly next year's first week etc. Even Angular's date filter showed incorrect data (it was 1st week of next year, angular gave week 53).

Note: Examples are designed to work with European weeks (Mon first)!

getWeek()

Date.prototype.getWeek = function(){

    // current week's Thursday
    var curWeek = new Date(this.getTime());
        curWeek.setDay(4);

    // Get year's first week's Thursday
    var firstWeek = new Date(curWeek.getFullYear(), 0, 4);
        firstWeek.setDay(4);

    return (curWeek.getDayIndex() - firstWeek.getDayIndex()) / 7 + 1;
};

setDay()

/**
* Make a setDay() prototype for Date
* Sets week day for the date
*/
Date.prototype.setDay = function(day){

    // Get day and make Sunday to 7
    var weekDay = this.getDay() || 7;
    var distance = day - weekDay;
    this.setDate(this.getDate() + distance);

    return this;
}

getDayIndex()

/*
* Returns index of given date (from Jan 1st)
*/

Date.prototype.getDayIndex = function(){
    var start = new Date(this.getFullYear(), 0, 0);
    var diff = this - start;
    var oneDay = 86400000;

    return Math.floor(diff / oneDay);
};

I have tested this and it seems to be working very well but if you notice a flaw in it, please let me know.

Your error is in UpdaterServiceManager in onCreate and showNotification method.

You are trying to show notification from Service using Activity Context. Whereas Every Service has its own Context, just use the that. You don't need to pass a Service an Activity's Context.I don't see why you need a specific Activity's Context to show Notification.

Put your createNotification method in UpdateServiceManager.class. And remove CreateNotificationActivity not from Service.

You cannot display an application window/dialog through a Context that is not an Activity. Try passing a valid activity reference

As mentioned before, you can manually edit your project's .csproj file in order to apply it manually.

I also noticed that Visual Studio 2013 attempts to apply a relative path to the reference hintpath, probably because of an attempt to make the project file more portable.

Since youre using JSON, I would Base64 Encode it before sending it across the wire.

If the files are large, try to look at BSON, or some other format that is better with binary transfers.

You could also zip the files, if they compress well, before base64 encoding them.

If you didn't want to use async/await inside your method, but still "decorate" it so as to be able to use the await keyword from outside, TaskCompletionSource.cs:

public static Task<T> RunAsync<T>(Func<T> function)
{ 
    if (function == null) throw new ArgumentNullException(“function”); 
    var tcs = new TaskCompletionSource<T>(); 
    ThreadPool.QueueUserWorkItem(_ =>          
    { 
        try 
        {  
           T result = function(); 
           tcs.SetResult(result);  
        } 
        catch(Exception exc) { tcs.SetException(exc); } 
   }); 
   return tcs.Task; 
}

From here and here

To support such a paradigm with Tasks, we need a way to retain the Task façade and the ability to refer to an arbitrary asynchronous operation as a Task, but to control the lifetime of that Task according to the rules of the underlying infrastructure that’s providing the asynchrony, and to do so in a manner that doesn’t cost significantly. This is the purpose of TaskCompletionSource.

I saw it's also used in the .NET source, e.g. WebClient.cs:

    [HostProtection(ExternalThreading = true)]
    [ComVisible(false)]
    public Task<string> UploadStringTaskAsync(Uri address, string method, string data)
    {
        // Create the task to be returned
        var tcs = new TaskCompletionSource<string>(address);

        // Setup the callback event handler
        UploadStringCompletedEventHandler handler = null;
        handler = (sender, e) => HandleCompletion(tcs, e, (args) => args.Result, handler, (webClient, completion) => webClient.UploadStringCompleted -= completion);
        this.UploadStringCompleted += handler;

        // Start the async operation.
        try { this.UploadStringAsync(address, method, data, tcs); }
        catch
        {
            this.UploadStringCompleted -= handler;
            throw;
        }

        // Return the task that represents the async operation
        return tcs.Task;
    }

Finally, I also found the following useful:

I get asked this question all the time. The implication is that there must be some thread somewhere that’s blocking on the I/O call to the external resource. So, asynchronous code frees up the request thread, but only at the expense of another thread elsewhere in the system, right? No, not at all.

To understand why asynchronous requests scale, I’ll trace a (simplified) example of an asynchronous I/O call. Let’s say a request needs to write to a file. The request thread calls the asynchronous write method. WriteAsync is implemented by the Base Class Library (BCL), and uses completion ports for its asynchronous I/O. So, the WriteAsync call is passed down to the OS as an asynchronous file write. The OS then communicates with the driver stack, passing along the data to write in an I/O request packet (IRP).

This is where things get interesting: If a device driver can’t handle an IRP immediately, it must handle it asynchronously. So, the driver tells the disk to start writing and returns a “pending” response to the OS. The OS passes that “pending” response to the BCL, and the BCL returns an incomplete task to the request-handling code. The request-handling code awaits the task, which returns an incomplete task from that method and so on. Finally, the request-handling code ends up returning an incomplete task to ASP.NET, and the request thread is freed to return to the thread pool.

Introduction to Async/Await on ASP.NET

If the target is to improve scalability (rather than responsiveness), it all relies on the existence of an external I/O that provides the opportunity to do that.

Modern browsers have support for document.getElementsByClassName. You can see the full breakdown of which vendors provide this functionality at caniuse. If you're looking to extend support into older browsers, you may want to consider a selector engine like that found in jQuery or a polyfill.

Older Answer

You'll want to check into jQuery, which will allow the following:

$(".classname").hide(); // hides everything with class 'classname'

Google offers a hosted jQuery source-file, so you can reference it and be up-and-running in moments. Include the following in your page:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
  $(function(){
    $(".classname").hide();
  });
</script>

In case you are considering using the numpy module, it makes this task very simple, as requested:

import numpy as np

j = np.array([4, 5, 6, 7, 1, 3, 7, 5])

j2 = np.sort(j[j >= 5])

The code inside of the brackets, j >= 5, produces a list of True or False values, which then serve as indices to select the desired values in j. Finally, we sort with the sort function built into numpy.

Tested result (a numpy array):

array([5, 5, 6, 7, 7])

I read all of the responses here and finally came up with a usable solution that is simple. The performance issues arise from the BETWEEN statement, not the generation of the row numbers themselves. So I used an algorithm to do dynamic paging by passing the page number and the number of records.

The passes are not start row and number of rows, but rather "rows per page (500)" and "page number (4)" which would be rows 1501 - 2000. These values can be replaced by stored procedure variables so you are not locked into using a specific paging amount.

select * from (
    select
        (((ROW_NUMBER() OVER(ORDER BY MyField) - 1) / 500) + 1) AS PageNum
        , *
    from MyTable
) as PagedTable
where PageNum = 4;

I recently had this problem as I was moving from Putty for Linux to Remmina for Linux. So I have a lot of PPK files for Putty in my .putty directory as I've been using it's for 8 years. For this I used a simple for command for bash shell to do all files:

cd ~/.putty
for X in *.ppk; do puttygen $X -L > ~/.ssh/$(echo $X | sed 's,./,,' | sed 's/.ppk//g').pub; puttygen $X -O private-openssh -o ~/.ssh/$(echo $X | sed 's,./,,' | sed 's/.ppk//g').pvk; done;

Very quick and to the point, got the job done for all files that putty had. If it finds a key with a password it will stop and ask for the password for that key first and then continue.

float: 32 bits (4 bytes) where 23 bits are used for the mantissa (about 7 decimal digits). 8 bits are used for the exponent, so a float can “move” the decimal point to the right or to the left using those 8 bits. Doing so avoids storing lots of zeros in the mantissa as in 0.0000003 (3 × 10^-7) or 3000000 (3 × 10⁷). There is 1 bit used as the sign bit.

double: 64 bits (8 bytes) where 52 bits are used for the mantissa (about 16 decimal digits). 11 bits are used for the exponent and 1 bit is the sign bit.

Since we are using binary (only 0 and 1), one bit in the mantissa is implicitly 1 (both float and double use this trick) when the number is non-zero.

Also, since everything is in binary (mantissa and exponents) the conversions to decimal numbers are usually not exact. Numbers like 0.5, 0.25, 0.75, 0.125 are stored exactly, but 0.1 is not. As others have said, if you need to store cents precisely, do not use float or double, use int, long, BigInteger or BigDecimal.

MongoDB needs data directory to store data. Default path is /data/db

When you start MongoDB engine, it searches this directory which is missing in your case. Solution is create this directory and assign rwx permission to user.

If you want to change the path of your data directory then you should specify it while starting mongod server like,

mongod --dbpath /data/<path> --port <port no> 

This should help you start your mongod server with custom path and port.

1. Connect to your SQL server instance using management studio
2. Goto Security -> Logins -> (RIGHT CLICK) New Login
3. fill in user details
4. Under User Mapping, select the databases you want the user to be able to access and configure

UPDATE:

You'll also want to goto Security -> Server Roles, and for public check the permissions for TSQL Default TCP/TSQL Default VIA/TSQL Local Machine/TSQL Named Pipesand remove the connect permission

Pool

• Pooling Mechanism is the way of creating the Objects in advance. When a class is loaded.
• It improves the application performance [By re using same object's to perform any action on Object-Data] & memory [allocating and de-allocating many objects creates a significant memory management overhead].
• Object clean-up is not required as we are using same Object, reducing the Garbage collection load.

« Pooling [ Object pool, String Constant Pool, Thread Pool, Connection pool]

String Constant pool

• String literal pool maintains only one copy of each distinct string value. which must be immutable.
• When the intern method is invoked, it check object availability with same content in pool using equals method. « If String-copy is available in the Pool then returns the reference. « Otherwise, String object is added to the pool and returns the reference.

Example: String to verify Unique Object from pool.

public class StringPoolTest {
    public static void main(String[] args) { // Integer.valueOf(), String.equals()
        String eol = System.getProperty("line.separator"); //java7 System.lineSeparator();

        String s1 = "Yash".intern();
        System.out.format("Val:%s Hash:%s SYS:%s "+eol, s1, s1.hashCode(), System.identityHashCode(s1));
        String s2 = "Yas"+"h".intern();
        System.out.format("Val:%s Hash:%s SYS:%s "+eol, s2, s2.hashCode(), System.identityHashCode(s2));
        String s3 = "Yas".intern()+"h".intern();
        System.out.format("Val:%s Hash:%s SYS:%s "+eol, s3, s3.hashCode(), System.identityHashCode(s3));
        String s4 = "Yas"+"h";
        System.out.format("Val:%s Hash:%s SYS:%s "+eol, s4, s4.hashCode(), System.identityHashCode(s4));

Connection pool using Type-4 Driver using 3rd party libraries[ DBCP2, c3p0, Tomcat JDBC]

Type 4 - The Thin driver converts JDBC calls directly into the vendor-specific database protocol Ex[Oracle - Thick, MySQL - Quora]. wiki

In Connection pool mechanism, when the class is loaded it get's the physical JDBC connection objects and provides a wrapped physical connection object to user. PoolableConnection is a wrapper around the actual connection.

• getConnection() pick one of the free wrapped-connection form the connection objectpool and returns it.
• close() instead of closing it returns the wrapped-connection back to pool.

OK, first of all I'm not sure how it works when you create a div using (document.createElement('div')), so I might be wrong now, but wouldn't it be possible to use the :target pseudo class selector for this?

If you look at the code below, you can se I've used a link to target the div, but in your case it might be possible to target #new from the script instead and that way make the div fade in without user interaction, or am I thinking wrong?

Here's the code for my example:

HTML

<a href="#new">Click</a> 
<div id="new">
    Fade in ... 
</div>

CSS

#new {
    width: 100px;
    height: 100px;
    border: 1px solid #000000;
    opacity: 0;    
}


#new:target {
    -webkit-transition: opacity 2.0s ease-in;
       -moz-transition: opacity 2.0s ease-in;
         -o-transition: opacity 2.0s ease-in;
                                  opacity: 1;
}

... and here's a jsFiddle

Looks like all you need is text-align: center; in ul

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.

To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".

To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".

Explanation:

From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):

4.3.8 ‘Local echo’

With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)

Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.

4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.

If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.

Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)

Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.

Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

I'm also facing this type of problem. After trying all solutions I got final solution on this problem. Reasons for this type of problem is per-defined global fonts. Use !important keyword for each line in @font-face is the solution for this problem.

Full description and example for Solution of this problem is here :- http://answerdone.blogspot.com/2017/06/font-face-not-working-solution.html

I think the keystore file you want to use has a different or unsupported format in respect to your Java version. Could you post some more info of your task?

In general, to solve this issue you might need to recreate the whole keystore (using some other JDK version for example). In export-import the keys between the old and the new one - if you manage to open the old one somewhere else.

If it is simply an unsupported version, try the BouncyCastle crypto provider for example (although I'm not sure If it adds support to Java for more keystore types?).

Edit: I looked at the feature spec of BC.

You can use this. react hooks

<input
                  type="number"
                  name="price"
                  placeholder="Enter price"
                  step="any"
                  required
                />

You can use Double.parseDouble() to convert a String to a double:

String text = "12.34"; // example String
double value = Double.parseDouble(text);

For your case it looks like you want:

double total = Double.parseDouble(jlbTotal.getText());
double price = Double.parseDouble(jlbPrice.getText());

PHP FILE

<?php
$target_path  = "./Upload/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file ".  basename( $_FILES['uploadedfile']['name']).
" has been uploaded";
} else{

you can use DateAdd on a trigger or a computed column if the timestamp you are adding is fixed or dependent of another column

I faced a similar issue on Docker for Ubuntu. It's a DNS issue. You will have to add Google Public DNS Settings into your network. Instruction for adding those settings is OS dependant. In my case, I was using Ubuntu so I added via network manager. Visit this site for more info.

v has 10 element, the index starts from 0 to 9.

for(int j=10;j>0;--j)
{
    cout<<v[j];   // v[10] out of range
}

you should update for loop to

for(int j=9; j>=0; --j)
//      ^^^^^^^^^^
{
    cout<<v[j];   // out of range
}

Or use reverse iterator to print element in reverse order

for (auto ri = v.rbegin(); ri != v.rend(); ++ri)
{
  std::cout << *ri << std::endl;
}

I'd construct a new data.frame:

d <- data.frame('a' = 1:3, 'b' = c('a','b','c'), 'c' = c('d', 'e', 'f'), 'd' = c('g', 'h', 'i')) 

cols <- c( 'b' , 'c' , 'd' )

data.frame(a = d[, 'a'], x = do.call(paste, c(d[ , cols], list(sep = '-'))))

If you want to stick with the original List instead of creating a new one, you can something similar to what the Distinct() extension method does internally, i.e. use a HashSet to check for uniqueness:

HashSet<long> set = new HashSet<long>(longs.Count);
longs.RemoveAll(x => !set.Add(x));

The List class provides this convenient RemoveAll(predicate) method that drops all elements not satisfying the condition specified by the predicate. The predicate is a delegate taking a parameter of the list's element type and returning a bool value. The HashSet's Add() method returns true only if the set doesn't contain the item yet. Thus by removing any items from the list that can't be added to the set you effectively remove all duplicates.

Do you want to delete a variable, don't you?

ok, I think I've got a best alternative idea to @bnaul's answer:

You can delete individual names with del:

del x

or you can remove them from the globals() object:

for name in dir():
    if not name.startswith('_'):
        del globals()[name]

This is just an example loop; it defensively only deletes names that do not start with an underscore, making a (not unreasoned) assumption that you only used names without an underscore at the start in your interpreter. You could use a hard-coded list of names to keep instead (whitelisting) if you really wanted to be thorough. There is no built-in function to do the clearing for you, other than just exit and restart the interpreter.

Modules you've imported (like import os) are going to remain imported because they are referenced by sys.modules; subsequent imports will reuse the already imported module object. You just won't have a reference to them in your current global namespace.

In Angular 2 and above, “everything is a component.” Components are the main way we build and specify elements and logic on the page, through both custom elements and attributes that add functionality to our existing components.

http://learnangular2.com/components/

But what directives do then in Angular2+ ?

Attribute directives attach behaviour to elements.

There are three kinds of directives in Angular:

1. Components—directives with a template.
2. Structural directives—change the DOM layout by adding and removing DOM elements.
3. Attribute directives—change the appearance or behaviour of an element, component, or another directive.

https://angular.io/docs/ts/latest/guide/attribute-directives.html

So what's happening in Angular2 and above is Directives are attributes which add functionalities to elements and components.

Look at the sample below from Angular.io:

import { Directive, ElementRef, Input } from '@angular/core';

@Directive({ selector: '[myHighlight]' })
export class HighlightDirective {
    constructor(el: ElementRef) {
       el.nativeElement.style.backgroundColor = 'yellow';
    }
}

So what it does, it will extends you components and HTML elements with adding yellow background and you can use it as below:

<p myHighlight>Highlight me!</p>

But components will create full elements with all functionalities like below:

import { Component } from '@angular/core';

@Component({
  selector: 'my-component',
  template: `
    <div>Hello my name is {{name}}. 
      <button (click)="sayMyName()">Say my name</button>
    </div>
   `
})
export class MyComponent {
  name: string;
  constructor() {
    this.name = 'Alireza'
  }
  sayMyName() {
    console.log('My name is', this.name)
  }
}

and you can use it as below:

<my-component></my-component>

When we use the tag in the HTML, this component will be created and the constructor get called and rendered.

Instead of JSONObject , you can use ObjectMapper to convert java object to json string

ObjectMapper mapper = new ObjectMapper();
String requestBean = mapper.writeValueAsString(yourObject);

in code there should be coma"," not colon ":"

the code must be $(this).css({'background-color' , '#FFFFEE'});

i hope it helps.

<span ng-if="verifyName.indicator == 1"><i class="fa fa-check"></i></span>
<span ng-if="verifyName.indicator == 0"><i class="fa fa-times"></i></span>

try this code. here verifyName.indicator value is coming from controller. this works for me.

The issue here is that JSON, as a format, is generally parsed in full and then handled in-memory, which for such a large amount of data is clearly problematic.

The solution to this is to work with the data as a stream - reading part of the file, working with it, and then repeating.

The best option appears to be using something like ijson - a module that will work with JSON as a stream, rather than as a block file.

Edit: Also worth a look - kashif's comment about json-streamer and Henrik Heino's comment about bigjson.

When Python parses the body of a function definition and encounters an assignment such as

feed = ...

Python interprets feed as a local variable by default. If you do not wish for it to be a local variable, you must put

global feed

in the function definition. The global statement does not have to be at the beginning of the function definition, but that is where it is usually placed. Wherever it is placed, the global declaration makes feed a global variable everywhere in the function.

Without the global statement, since feed is taken to be a local variable, when Python executes

feed = feed + 1,

Python evaluates the right-hand side first and tries to look up the value of feed. The first time through it finds feed is undefined. Hence the error.

The shortest way to patch up the code is to add global feed to the beginning of onLoadFinished. The nicer way is to use a class:

class Page(object):
    def __init__(self):
        self.feed = 0
    def onLoadFinished(self, result):
        ...
        self.feed += 1

The problem with having functions which mutate global variables is that it makes it harder to grok your code. Functions are no longer isolated units. Their interaction extends to everything that affects or is affected by the global variable. Thus it makes larger programs harder to understand.

By avoiding mutating globals, in the long run your code will be easier to understand, test and maintain.

We'd used SOAPpy from Python Web Services, but it seems that ZSI (same source) is replacing it.

When using WebAPI, you should just return the Object rather than specifically returning Json, as the API will either return JSON or XML depending on the request.

I am not sure why your WebAPI is returning an ActionResult, but I would change the code to something like;

public IEnumerable<ListItems> GetAllNotificationSettings()
{
    var result = new List<ListItems>();
    // Filling the list with data here...

    // Then I return the list
    return result;
}

This will result in JSON if you are calling it from some AJAX code.

P.S WebAPI is supposed to be RESTful, so your Controller should be called ListItemController and your Method should just be called Get. But that is for another day.

If you are going to manage your memory manually, you have two cases:

1. I created the object (perhaps indirectly, by calling a function that allocates a new object), I use it (or a function I call uses it), then I free it.
2. Somebody gave me the reference, so I should not free it.

If you need to break any of these rules, please document it.

It is all about pointer ownership.

My solution,

load the app using

NODE_ENV=production node app.js

Then setup config.js as a function rather than an object

module.exports = function(){
    switch(process.env.NODE_ENV){
        case 'development':
            return {dev setting};

        case 'production':
            return {prod settings};

        default:
            return {error or other settings};
    }
};

Then as per Jans solution load the file and create a new instance which we could pass in a value if needed, in this case process.env.NODE_ENV is global so not needed.

var Config = require('./conf'),
    conf = new Config();

Then we can access the config object properties exactly as before

conf.twitter.consumerKey

I think the best option is:

1. Create a model class as config schema

2. Register in DI: services.Configure(Configuration.GetSection("democonfig"));

3. Get the values as model object from DI in your controller:

   private readonly your_model myConfig;
   public DemoController(IOptions<your_model> configOps)
   {
       this.myConfig = configOps.Value;
   }
   

If you need to check whether the elements of one vector are in another, the best solution is ismember as mentioned in the other answers.

ismember([15 17],primes(20))

However when you are dealing with floating point numbers, or just want to have close matches (+- 1000 is also possible), the best solution I found is the fairly efficient File Exchange Submission: ismemberf

It gives a very practical example:

[tf, loc]=ismember(0.3, 0:0.1:1) % returns false 
[tf, loc]=ismemberf(0.3, 0:0.1:1) % returns true

Though the default tolerance should normally be sufficient, it gives you more flexibility

ismemberf(9.99, 0:10:100) % returns false
ismemberf(9.99, 0:10:100,'tol',0.05) % returns true

At the risk of irritating you;

You're asking the wrong question. You don't need a reason NOT to deviate from the defaults, but the other way around. You need a reason to do so. Timeouts are absolutely essential when running a web server and to disable that setting without a reason is inherently contrary to good practice, even if it's running on a web server that happens to have a timeout directive of its own.

Now, as for the real answer; probably it doesn't matter at all in this particular case, but it's bad practice to go by the setting of a separate system. What if the script is later run on a different server with a different timeout? If you can safely say that it will never happen, fine, but good practice is largely about accounting for seemingly unlikely events and not unnecessarily tying together the settings and functionality of completely different systems. The dismissal of such principles is responsible for a lot of pointless incompatibilities in the software world. Almost every time, they are unforeseen.

What if the web server later is set to run some other runtime environment which only inherits the timeout setting from the web server? Let's say for instance that you later need a 15-year-old CGI program written in C++ by someone who moved to a different continent, that has no idea of any timeout except the web server's. That might result in the timeout needing to be changed and because PHP is pointlessly relying on the web server's timeout instead of its own, that may cause problems for the PHP script. Or the other way around, that you need a lesser web server timeout for some reason, but PHP still needs to have it higher.

It's just not a good idea to tie the PHP functionality to the web server because the web server and PHP are responsible for different roles and should be kept as functionally separate as possible. When the PHP side needs more processing time, it should be a setting in PHP simply because it's relevant to PHP, not necessarily everything else on the web server.

In short, it's just unnecessarily conflating the matter when there is no need to.

Last but not least, 'stillstanding' is right; you should at least rather use set_time_limit() than ini_set().

Hope this wasn't too patronizing and irritating. Like I said, probably it's fine under your specific circumstances, but it's good practice to not assume your circumstances to be the One True Circumstance. That's all. :)

You can also try this. If you like the model view controller concept and fast prototyping then I would say you will like the idea behind it;)

SimpleUi ( https://github.com/bitstars/SimpleUi )

The generated UI (code below):

The complete code to create this Android UI:

I use it in real applications, not only for fast prototyping or dialogs and its well tested over the years. The concept is based on the model view control principle and for most common scenarios there are ready to use components which automatically look correct on any device. I don't say it should be used for any UI (e.g. listviews should be done by hand) but for most usecases this should be quite handy ;) Oh and feel free to fork it and improve it further if you want

For multiple text boxes - add them into a list and show all errors into 1 messagebox.

// Append errors into 1 Message Box      

 List<string> errors = new List<string>();   

 if (string.IsNullOrEmpty(textBox1.Text))
    {
        errors.Add("User");
    }

    if (string.IsNullOrEmpty(textBox2.Text))
    {
        errors.Add("Document Ref Code");
    }

    if (errors.Count > 0)
    {
        errors.Insert(0, "The following fields are empty:");
        string message = string.Join(Environment.NewLine, errors);
        MessageBox.Show(message, "errors", MessageBoxButtons.OK, MessageBoxIcon.Warning);
        return;
    } 

Change the return type to Nullable<T>, and call the method with the non nullable parameter

static void Main(string[] args)
{
    int? i = GetValueOrNull<int>(null, string.Empty);
}


public static Nullable<T> GetValueOrNull<T>(DbDataRecord reader, string columnName) where T : struct
{
    object columnValue = reader[columnName];

    if (!(columnValue is DBNull))
        return (T)columnValue;

    return null;
}

$_SERVER['HTTP_HOST'] 

//to get the domain

$protocol=strpos(strtolower($_SERVER['SERVER_PROTOCOL']),'https') === FALSE ? 'http' : 'https';
$domainLink=$protocol.'://'.$_SERVER['HTTP_HOST'];

//domain with protocol

$url=$protocol.'://'.$_SERVER['HTTP_HOST'].'?'.$_SERVER['QUERY_STRING'];

//protocol,domain,queryString total **As the $_SERVER['SERVER_NAME'] is not reliable for multi domain hosting!

Icesoap, which I found yesterday, looks promising. It worked on a basic test, but it lacks more examples.

As mentioned in the React documentation, there is no guarantee of setState being fired synchronously, so your console.log may return the state prior to it updating.

Michael Parker mentions passing a callback within the setState. Another way to handle the logic after state change is via the componentDidUpdate lifecycle method, which is the method recommended in React docs.

Generally we recommend using componentDidUpdate() for such logic instead.

This is particularly useful when there may be successive setStates fired, and you would like to fire the same function after every state change. Rather than adding a callback to each setState, you could place the function inside of the componentDidUpdate, with specific logic inside if necessary.

// example
componentDidUpdate(prevProps, prevState) {
  if (this.state.value > prevState.value) {
    this.foo();  
  }
}

I created a custom function.

def exists(var):
     return var in globals()

Then the call the function like follows replacing variable_name with the variable you want to check:

exists("variable_name")

Will return True or False

xmlns - xml namespace. It's just a method to avoid element name conflicts. For example:

<config xmlns:rnc="URI1" xmlns:bsc="URI2">
  <rnc:node>
      <rnc:rncId>5</rnc:rncId>
  </rnc:node>

  <bsc:node>
      <bsc:cId>5</bsc:cId>
  </bsc:node>
</config>

Two different node elements in one xml file. Without namespaces this file would not be valid.

numpy.fromiter() is what you are looking for:

big_array = numpy.fromiter(xrange(5), dtype="int")

It also works with generator expressions, e.g.:

big_array = numpy.fromiter( (i*(i+1)/2 for i in xrange(5)), dtype="int" )

If you know the length of the array in advance, you can specify it with an optional 'count' argument.

The only problem with threads is accessing the same object from different threads without synchronization.

If each function only uses parameters for reading and local variables, they don't need any synchronization to be thread-safe.

If you have a rogue loop, pause the code in Google Chrome debugger (the small "||" button while in Sources tab).

Switch back to Chrome itself, open "Task Manager" (Shift+ESC), select your tab, click the "End Process" button.

You will get the Aww Snap message and then you can reload (F5).

As others have noted, reloading the page at the point of pausing is the same as restarting the rogue loop and can cause nasty lockups if the debugger also then locks (in some cases leading to restarting chrome or even the PC). The debugger needs a "Stop" button. Nb: The accepted answer is out of date in that some aspects of it are now apparently wrong. If you vote me down, pls explain :).

Set the "AutoSizeColumnsMode" property to "Fill".. By default it is set to 'NONE'. Now columns will be filled across the DatagridView. Then you can set the width of other columns accordingly.

DataGridView1.Columns[0].Width=100;// The id column 
DataGridView1.Columns[1].Width=200;// The abbrevation columln
//Third Colulmns 'description' will automatically be resized to fill the remaining 
//space

Make sure you log into psql as the owner of the tables. to find out who own the tables use \dt

psql -h CONNECTION_STRING DBNAME -U OWNER_OF_THE_TABLES

then you can run the GRANTS

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

 marker.setVisible(false);

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

This works great

.create:before{
    content: "";
    display: block;
    background: url('somewhere.jpg') no-repeat;
    width: 25px;
    height: 25px;
    float: left;
}

Another way is download and unzip chromedriver and put 'chromedriver.exe' in C:\Python27\Scripts and then you need not to provide the path of driver, just

driver= webdriver.Chrome()

will work

The "if" expression tests for truthiness, while the double-equal tests for type-independent equivalency. A string is always truthy, as others here have pointed out. If the double-equal were testing both of its operands for truthiness and then comparing the results, then you'd get the outcome you were intuitively assuming, i.e. ("0" == true) === true. As Doug Crockford says in his excellent JavaScript: the Good Parts, "the rules by which [== coerces the types of its operands] are complicated and unmemorable.... The lack of transitivity is alarming." It suffices to say that one of the operands is type-coerced to match the other, and that "0" ends up being interpreted as a numeric zero, which is in turn equivalent to false when coerced to boolean (or false is equivalent to zero when coerced to a number).

There is a difference in performance.

Simply put HS256 is about 1 order of magnitude faster than RS256 for verification but about 2 orders of magnitude faster than RS256 for issuing (signing).

 640,251  91,464.3 ops/s
  86,123  12,303.3 ops/s (RS256 verify)
   7,046   1,006.5 ops/s (RS256 sign)

Don't get hung up on the actual numbers, just think of them with respect of each other.

Simple feature added in rails 2.3.4, db/seeds.rb

Provides a new rake task

rake db:seed

Good for populating common static records like states, countries, etc...

http://railscasts.com/episodes/179-seed-data

*Note that you can use fixtures if you had already created them to also populate with the db:seed task by putting the following in your seeds.rb file (from the railscast episode):

require 'active_record/fixtures'
Fixtures.create_fixtures("#{Rails.root}/test/fixtures", "operating_systems")

For Rails 3.x use 'ActiveRecord::Fixtures' instead of 'Fixtures' constant

require 'active_record/fixtures'
ActiveRecord::Fixtures.create_fixtures("#{Rails.root}/test/fixtures", "fixtures_file_name")

You can len(list(generator)) but you could probably make something more efficient if you really intend to discard the results.

Please make sure at first that

1. you are using InnoDB tables.
2. field for FOREIGN KEY has the same type and length (!) as source field.

I had the same trouble and I've fixed it. I had unsigned INT for one field and just integer for other field.

This should do the trick

'g' in df.index

I'm using Eclipse and I copied your code and got the same error. I then opened up the project properties->Java Build Path -> Libraries->Add External JARs... c:\jrun4\lib\sqlitejdbc-v056.jar Worked like a charm. You may need to restart your web server if you've just copied the .jar file.

Add the following code in your HTML page, and it will show print preview on page load.

<head>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>

<script type="text/javascript">

$(document).ready(function () {
    window.print();
});

</script>

You forgot to add the global operator. Use this:

var s = "04.07.2012";_x000D_
alert(s.replace(new RegExp("[0-9]","g"), "X")); 

Most of the answers address how to add a column safely in a stored procedure, I had the need to add a column to a table safely without using a stored proc and discovered that MySQL does not allow the use of IF Exists() outside a SP. I'll post my solution that it might help someone in the same situation.

SELECT count(*)
INTO @exist
FROM information_schema.columns 
WHERE table_schema = database()
and COLUMN_NAME = 'original_data'
AND table_name = 'mytable';

set @query = IF(@exist <= 0, 'alter table intent add column mycolumn4 varchar(2048) NULL after mycolumn3', 
'select \'Column Exists\' status');

prepare stmt from @query;

EXECUTE stmt;

This will work although when embedding PHP in HTML it is better practice to use the following form:

<table>
    <?php foreach($array as $key=>$value): ?>
    <tr>
        <td><?= $key; ?></td>
    </tr>
    <?php endforeach; ?>
</table>

You can find the doc for the alternative syntax on PHP.net

Answer to my question (after several Google searches) revealed the following:

$ curl https://pkgconfig.freedesktop.org/releases/pkg-config-0.29.tar.gz -o pkgconfig.tgz
$ tar -zxf pkgconfig.tgz && cd pkg-config-0.29
$ ./configure && make install

Thanks to everyone for their comments, and sorry for my linux/OSX ignorance!

Doing this fixed my issues as mentioned above.

Iterators:

Iterator are objects which uses next() method to get next value of sequence.

Generators:

A generator is a function that produces or yields a sequence of values using yield method.

Every next() method call on generator object(for ex: f as in below example) returned by generator function(for ex: foo() function in below example), generates next value in sequence.

When a generator function is called, it returns an generator object without even beginning execution of the function. When next() method is called for the first time, the function starts executing until it reaches yield statement which returns the yielded value. The yield keeps track of i.e. remembers last execution. And second next() call continues from previous value.

The following example demonstrates the interplay between yield and call to next method on generator object.

>>> def foo():
...     print "begin"
...     for i in range(3):
...         print "before yield", i
...         yield i
...         print "after yield", i
...     print "end"
...
>>> f = foo()
>>> f.next()
begin
before yield 0            # Control is in for loop
0
>>> f.next()
after yield 0             
before yield 1            # Continue for loop
1
>>> f.next()
after yield 1
before yield 2
2
>>> f.next()
after yield 2
end
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
StopIteration

this is for classes

$('.nameofdiv').val('we are developers');

for ids

$('#nameofdiv').val('we are developers');

now if u have an iput in a form u can use

$("#form li.name input.name_val").val('we are awsome developers');

var iframe = document.getElementById('iframeId');
var innerDoc = (iframe.contentDocument) ? iframe.contentDocument : iframe.contentWindow.document;

You could more simply write:

var iframe = document.getElementById('iframeId');
var innerDoc = iframe.contentDocument || iframe.contentWindow.document;

and the first valid inner doc will be returned.

Once you get the inner doc, you can just access its internals the same way as you would access any element on your current page. (innerDoc.getElementById...etc.)

IMPORTANT: Make sure that the iframe is on the same domain, otherwise you can't get access to its internals. That would be cross-site scripting.

The urlArgs solution has problems. Unfortunately you cannot control all proxy servers that might be between you and your user's web browser. Some of these proxy servers can be unfortunately configured to ignore URL parameters when caching files. If this happens, the wrong version of your JS file will be delivered to your user.

I finally gave up and implemented my own fix directly into require.js. If you are willing to modify your version of the requirejs library, this solution might work for you.

You can see the patch here:

https://github.com/jbcpollak/requirejs/commit/589ee0cdfe6f719cd761eee631ce68eee09a5a67

Once added, you can do something like this in your require config:

var require = {
    baseUrl: "/scripts/",
    cacheSuffix: ".buildNumber"
}

Use your build system or server environment to replace buildNumber with a revision id / software version / favorite color.

Using require like this:

require(["myModule"], function() {
    // no-op;
});

Will cause require to request this file:

http://yourserver.com/scripts/myModule.buildNumber.js

On our server environment, we use url rewrite rules to strip out the buildNumber, and serve the correct JS file. This way we don't actually have to worry about renaming all of our JS files.

The patch will ignore any script that specifies a protocol, and it will not affect any non-JS files.

This works well for my environment, but I realize some users would prefer a prefix rather than a suffix, it should be easy to modify my commit to suit your needs.

Update:

In the pull request discussion, the requirejs author suggest this might work as a solution to prefix the revision number:

var require = {
    baseUrl: "/scripts/buildNumber."
};

I have not tried this, but the implication is that this would request the following URL:

http://yourserver.com/scripts/buildNumber.myModule.js

Which might work very well for many people who can use a prefix.

Here are some possible duplicate questions:

RequireJS and proxy caching

require.js - How can I set a version on required modules as part of the URL?

var http = require("http");
var url = "http://api.example.com/api/v1/?param1=1&param2=2";

var options = {
    host: "http://api.example.com",
    port: 80,
    method: "GET",
    path: url,//I don't know for some reason i have to use full url as a path
    auth: username + ':' + password
};

http.get(options, function(rs) {
    var result = "";
    rs.on('data', function(data) {
        result += data;
    });
    rs.on('end', function() {
        console.log(result);
    });
});

you can try in this way if you are using thymeleaf

sec:authorize="hasAnyRole(T(com.orsbv.hcs.model.SystemRole).ADMIN.getName(),
               T(com.orsbv.hcs.model.SystemRole).SUPER_USER.getName(),'ROLE_MANAGEMENT')"

this will return true if the user has the mentioned roles,false otherwise.

Please note you have to use sec tag in your html declaration tag like this

<html xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">

Add "new":

var movies = _db.Movies.OrderBy( m => new { m.CategoryID, m.Name })

That works on my box. It does return something that can be used to sort. It returns an object with two values.

Similar, but different to sorting by a combined column, as follows.

var movies = _db.Movies.OrderBy( m => (m.CategoryID.ToString() + m.Name))

You may want to consider using a different type of loop where that logic is applicable, because it is the most obvious answer.

perhaps a:

i=2
while i < n:
    if something:
       do something
       i += 1
    else: 
       do something else  
       i = 2 #restart the loop  

          <Scatter
            data={data}
            // style={{ width: "50%", height: "50%" }}
            options={{
              scales: {
                yAxes: [
                  {
                    scaleLabel: {
                      display: true,
                      labelString: "Probability",
                    },
                  },
                ],
                xAxes: [
                  {
                    scaleLabel: {
                      display: true,
                      labelString: "Hours",
                    },
                  },
                ],
              },
            }}
          />

I don't think you can do it in one line of code. Try opening your activities with startActivityForResult. As the result you can pass something like a CLOSE_FLAG, which will inform your parent activity that its child activity has finished.

That said, you should probably read this answer.

notebook version

I was facing a similar issue. Actually the command is :

java -version and not java --version.

You will get output something like this:

How do I finish the merge after resolving my merge conflicts?

With Git 2.12 (Q1 2017), you will have the more natural command:

git merge --continue

See commit c7d227d (15 Dec 2016) by Jeff King (peff).
See commit 042e290, commit c261a87, commit 367ff69 (14 Dec 2016) by Chris Packham (cpackham).
^{(Merged by Junio C Hamano -- gitster -- in commit 05f6e1b, 27 Dec 2016)}

See 2.12 release notes.

merge: add '--continue' option as a synonym for 'git commit'

Teach 'git merge' the --continue option which allows 'continuing' a merge by completing it.
The traditional way of completing a merge after resolving conflicts is to use 'git commit'.
Now with commands like 'git rebase' and 'git cherry-pick' having a '--continue' option adding such an option to 'git merge' presents a consistent UI.

I had the same error because I didn't issued a Let's Encrypt cert for the www.my-domain.com, only for my-domain.com

Issuing also for the www. and configuring the vhost to load certificates for www.my-domain.com before redirecting to https://my-domain.com did the trick.

Use list, it will solve problem

Step1:

 result=YOUR_MODELE_NAME.objects.values('PROP1','PROP2').all();

Step2:

 result=list(result)  #after getting data from model convert result to list

Step3:

 return HttpResponse(json.dumps(result), content_type = "application/json")

Update 2019

I tried easy_install at first but it doesn't install packages in a clean and intuitive way. Also when it comes time to remove packages it left a lot of artifacts that needed to be cleaned up.

sudo yum install epel-release
sudo yum install python34-pip
pip install package

Was the solution that worked for me, it installs "pip3" as pip on the system. It also uses standard rpm structure so it clean in its removal. I am not sure what process you would need to take if you want both python2 and python3 package manager on your system.

This is not something that SVG 1.1 supports. SVG 1.2 does have the textArea element, with automatic word wrapping, but it's not implemented in all browsers. SVG 2 does not plan on implementing textArea, but it does have auto-wrapped text.

However, given that you already know where your linebreaks should occur, you can break your text into multiple <tspan>s, each with x="0" and dy="1.4em" to simulate actual lines of text. For example:

<g transform="translate(123 456)"><!-- replace with your target upper left corner coordinates -->
  <text x="0" y="0">
    <tspan x="0" dy="1.2em">very long text</tspan>
    <tspan x="0" dy="1.2em">I would like to linebreak</tspan>
  </text>
</g>

Of course, since you want to do that from JavaScript, you'll have to manually create and insert each element into the DOM.

No. = sets somevar to have that value. use === to compare value and type which returns a boolean that you need.

Never use or suggest == instead of ===. its a recipe for disaster. e.g 0 == "" is true but "" == '0' is false and many more.

I hope that helps.

You need to switch your values:

/* No greater than 900px, no less than 400px */
@media (max-width:900px) and (min-width:400px) {
    .foo {
        display:none;
    }
}?

I have the solution for this due to I have a similar problem today.

Supposed you want to open http://google.com from an app running with admin priviliges:

ProcessStartInfo startInfo = new ProcessStartInfo("iexplore.exe", "http://www.google.com/");
Process.Start(startInfo); 

This dplyr method works nicely when piping.

For selected columns:

library(dplyr)
iris %>% 
  select(Sepal.Width, Species) %>% 
  t %>% c %>% unique

 [1] "3.5"        "setosa"     "3.0"        "3.2"        "3.1"       
 [6] "3.6"        "3.9"        "3.4"        "2.9"        "3.7"       
[11] "4.0"        "4.4"        "3.8"        "3.3"        "4.1"       
[16] "4.2"        "2.3"        "versicolor" "2.8"        "2.4"

You can use both jQuery and $ in below snippet. it worked for me

jQuery( document ).ready(function( $ ) {
  // jQuery(document)
  // $(document)
});

Example 1:

0 means ignore

1 means show

User.find({}, { createdAt: 0, updatedAt: 0, isActive: 0, _id : 1 }).then(...)

Example 2:

User.findById(id).select("_id, isActive").then(...)

You could use the nuget package Newtonsoft.JSON in order to achieve this:

JsonConvert.DeserializeObject<List<Response>>(yourJsonString)

As @Roko mentioned you can do this in multiple ways.

1.Using the jQuery first-child selector - SnoopCode

   $(document).ready(function(){
    $(".alldivs onediv:first-child").css("background-color","yellow");
        }

2. Using jQuery eq Selector - SnoopCode

    $( "body" ).find( "onediv" ).eq(1).addClass( "red" );
   

3. Using jQuery Id Selector - SnoopCode

      $(document).ready(function(){
        $("#div1").css("background-color: red;");
      });
   

Png files can handle transparency. So you could use this question Save plot to image file instead of displaying it using Matplotlib so as to save you graph as a png file.

And if you want to turn all white pixel transparent, there's this other question : Using PIL to make all white pixels transparent?

If you want to turn an entire area to transparent, then there's this question: And then use the PIL library like in this question Python PIL: how to make area transparent in PNG? so as to make your graph transparent.

You can use animated background-position property and sprite image.

you can use commons csv to convert into CSV format. or use POI to convert into xls. if you need helper to convert into xls, you can use jxls, it can convert java bean (or list) into excel with expression language.

Basically, the json doc maybe is a json array, right? so it will be same. the result will be list, and you just write the property that you want to display in excel format that will be read by jxls. See http://jxls.sourceforge.net/reference/collections.html

If the problem is the json can't be read in the jxls excel property, just serialize it into collection of java bean first.

This solution is purely using ng tag on HTML.

The solution is to limit the long text displayed with 'show more...' link at the end of it. If user click 'show more...' link, it will show the rest of the text and removed the 'show more...' link.

HTML:

<div ng-init="limitText=160">
   <p>{{ veryLongText | limitTo: limitText }} 
       <a href="javascript:void(0)" 
           ng-hide="veryLongText.length < limitText" 
           ng-click="limitText = veryLongText.length + 1" > show more..
       </a>
   </p>
</div>
