Exit [construct], and intelisense will tell you which one(s) are valid in a particular place.

Here you go:

$( table ).delegate( '.tr_clone_add', 'click', function () {
    var thisRow = $( this ).closest( 'tr' )[0];
    $( thisRow ).clone().insertAfter( thisRow ).find( 'input:text' ).val( '' );
});

Update: The new way of delegating events in jQuery is

$(table).on('click', '.tr_clone_add', function () { … });

I was playing around with ways to restart a container. What I found for me was this solution:

Dockerfile:

...
ENTRYPOINT [ "/app/bootstrap.sh" ]

/app/bootstrap.sh:

#!/bin/bash
/app/startWhatEverYouActuallyWantToStart.sh &
tail -f /dev/null

Whenever I want to restart the container, I kill the process with tail -f /dev/null which I find with

kill -TERM `ps --ppid 1 | grep tail | grep -v -e grep | awk '{print $1}'`

Following that command, all the processes except for the one with PID==1 will be killed and the entrypoint, in my case bootstrap.sh will be executed (again).

That's for the part "restart" - which is not really a restart but it does what you wish, in the end. For the part with limiting restarting the container named container-test you could pass on the container name to the container in question (as the container name would otherwise not be available inside the container) and then you can decide whether to do the above kill. That would be something like this in your deployment.yaml:

    env:
    - name: YOUR_CONTAINER_NAME
      value: container-test

/app/startWhatEverYouActuallyWantToStart.sh:

#!/bin/bash
...
CONDITION_TO_RESTART=0
...
if [ "$YOUR_CONTAINER_NAME" == "container-test" -a $CONDITION_TO_RESTART -eq 1 ]; then
    kill -TERM `ps --ppid 1 | grep tail | grep -v -e grep | awk '{print $1}'`
fi

You could use the JS confirm function.

<form onSubmit="if(!confirm('Is the form filled out correctly?')){return false;}">
  <input type="submit" />
</form>

Fuzzy Wuzzy is a package that implements Levenshtein distance in python, with some helper functions to help in certain situations where you may want two distinct strings to be considered identical. For example:

>>> fuzz.ratio("fuzzy wuzzy was a bear", "wuzzy fuzzy was a bear")
    91
>>> fuzz.token_sort_ratio("fuzzy wuzzy was a bear", "wuzzy fuzzy was a bear")
    100

git gc --prune=now is not what you want.

git remote prune public

or git remote prune origin # if thats the the remote source

I update my Hibernate JPA to 2.1 and It works.

<dependency>
    <groupId>org.hibernate.javax.persistence</groupId>
    <artifactId>hibernate-jpa-2.1-api</artifactId>
    <version>1.0.0.Final</version>
</dependency>

Because QuerySets implement the Python __or__ operator (|), or union, it just works. As you'd expect, the | binary operator returns a QuerySet so order_by(), .distinct(), and other queryset filters can be tacked on to the end.

combined_queryset = User.objects.filter(income__gte=5000) | User.objects.filter(income__isnull=True)
ordered_queryset = combined_queryset.order_by('-income')

Update 2019-06-20: This is now fully documented in the Django 2.1 QuerySet API reference. More historic discussion can be found in DjangoProject ticket #21333.

Simpler, shorter, faster: EXISTS.

IF EXISTS (SELECT 1 FROM people p WHERE p.person_id = my_person_id) THEN
  -- do something
END IF;

The query planner can stop at the first row found - as opposed to count(), which will scan all matching rows regardless. Makes a difference with big tables. Hardly matters with a condition on a unique column - only one row qualifies anyway (and there is an index to look it up quickly).

^{Improved with input from @a_horse_with_no_name in the comments below.}

You could even use an empty SELECT list:

IF EXISTS (SELECT FROM people p WHERE p.person_id = my_person_id) THEN ...

Since the SELECT list is not relevant to the outcome of EXISTS. Only the existence of at least one qualifying row matters.

I made the following module called unicoder to be able to do the transformation on variables:

import sys
import os

def ustr(string):

    string = 'u"%s"'%string

    with open('_unicoder.py', 'w') as script:

        script.write('# -*- coding: utf-8 -*-\n')
        script.write('_ustr = %s'%string)

    import _unicoder
    value = _unicoder._ustr

    del _unicoder
    del sys.modules['_unicoder']

    os.system('del _unicoder.py')
    os.system('del _unicoder.pyc')

    return value

Then in your program you could do the following:

# -*- coding: utf-8 -*-

from unicoder import ustr

txt = 'Hello, Unicode World'
txt = ustr(txt)

print type(txt) # <type 'unicode'>

I'm pretty sure the code is not using the System.Net.Http.HttpContent class, but instead Microsoft.Http.HttpContent. Microsoft.Http was the WCF REST Starter Kit, which never made it out preview before being placed in the .NET Framework. You can still find it here: http://aspnet.codeplex.com/releases/view/24644

I would not recommend basing new code on it.

You need to do some escaping I think.

None of this is a creation time. Most Unix filesystems don't support creation timestamps.

I've noticed that sometimes when switching git branches, Visual Studio (2017) will not recognize types from some files that had been added in the second branch. Deleting the .vs folder solves it, but it also trashes all your workspace settings. This trick seems to work well for me:

1. Solution Explorer -> Find the file with the unrecognized class in it.
2. Click Show All Files at the top of the Solution Explorer.
3. Right-click the file -> Exclude from project.
4. Right-click the file again -> Include in project.

This causes Intellisense to parse the file that it missed when switching branches.

In Designer, activate the centralWidget and assign a layout, e.g. horizontal or vertical layout. Then your QFormLayout will automatically resize.

Always make sure, that all widgets have a layout! Otherwise, automatic resizing will break with that widget!

Add new column to DataTable and use column Expression property to set your Status expression.

Here you can find good example: DataColumn.Expression Property

DataTable and DataColumn Expressions in ADO.NET - Calculated Columns

UPDATE

Code sample:

DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("colBestBefore", typeof(DateTime)));
dt.Columns.Add(new DataColumn("colStatus", typeof(string)));

dt.Columns["colStatus"].Expression = String.Format("IIF(colBestBefore < #{0}#, 'Ok','Not ok')", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));

dt.Rows.Add(DateTime.Now.AddDays(-1));
dt.Rows.Add(DateTime.Now.AddDays(1));
dt.Rows.Add(DateTime.Now.AddDays(2));
dt.Rows.Add(DateTime.Now.AddDays(-2));

demoGridView.DataSource = dt;

UPDATE #2

dt.Columns["colStatus"].Expression = String.Format("IIF(CONVERT(colBestBefore, 'System.DateTime') < #{0}#, 'Ok','Not ok')", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));

By referring this(http://www.excelforum.com/excel-programming-vba-macros/867665-application-cutcopymode-false.html) link the answer is as below:

Application.CutCopyMode=False is seen in macro recorder-generated code when you do a copy/cut cells and paste . The macro recorder does the copy/cut and paste in separate statements and uses the clipboard as an intermediate buffer. I think Application.CutCopyMode = False clears the clipboard. Without that line you will get the warning 'There is a large amount of information on the Clipboard....' when you close the workbook with a large amount of data on the clipboard.

With optimised VBA code you can usually do the copy/cut and paste operations in one statement, so the clipboard isn't used and Application.CutCopyMode = False isn't needed and you won't get the warning.

You can push a branch to a remote server, say github. You would first have to do the initial project setup, then clone your project and:

git push <remote repo> <your branch>

Your user settings are in ~/Library/Application\ Support/Code/User.

If you're not concerned about syncing and it's a one time thing, you can just copy the files keybindings.json and settings.json to the corresponding folder on your new machine.

Your extensions are in the ~/.vscode folder. Most extensions aren't using any native bindings and they should be working properly when copied over. You can manually re-install those who do not.

The IIS7 module will let you redirect.

To write to a log file and make a new one each day, you could use date("j.n.Y") as part of the filename.

//Something to write to txt log
$log  = "User: ".$_SERVER['REMOTE_ADDR'].' - '.date("F j, Y, g:i a").PHP_EOL.
        "Attempt: ".($result[0]['success']=='1'?'Success':'Failed').PHP_EOL.
        "User: ".$username.PHP_EOL.
        "-------------------------".PHP_EOL;
//Save string to log, use FILE_APPEND to append.
file_put_contents('./log_'.date("j.n.Y").'.log', $log, FILE_APPEND);

So you would place that within your hasAccess() method.

public function hasAccess($username,$password){
    $form = array();
    $form['username'] = $username;
    $form['password'] = $password;

    $securityDAO = $this->getDAO('SecurityDAO');
    $result = $securityDAO->hasAccess($form);

    //Write action to txt log
    $log  = "User: ".$_SERVER['REMOTE_ADDR'].' - '.date("F j, Y, g:i a").PHP_EOL.
            "Attempt: ".($result[0]['success']=='1'?'Success':'Failed').PHP_EOL.
            "User: ".$username.PHP_EOL.
            "-------------------------".PHP_EOL;
    //-
    file_put_contents('./log_'.date("j.n.Y").'.txt', $log, FILE_APPEND);

    if($result[0]['success']=='1'){
        $this->Session->add('user_id', $result[0]['id']);
        //$this->Session->add('username', $result[0]['username']);
        //$this->Session->add('roleid', $result[0]['roleid']);
        return $this->status(0,true,'auth.success',$result);
    }else{
        return $this->status(0,false,'auth.failed',$result);
    }
}

Darren Davies is partially correct in saying that you should use a salt - there are several issues with his claim that MD5 is insecure.

You've said that you have to insert the password using an Md5 hash, but that doesn't really tell us why. Is it because that's the format used when validatinb the password? Do you have control over the code which validates the password?

The thing about using a salt is that it avoids the problem where 2 users have the same password - they'll also have the same hash - not a desirable outcome. By using a diferent salt for each password then this does not arise (with very large volumes of data there is still a risk of collisions arising from 2 different passwords - but we'll ignore that for now).

So you can aither generate a random value for the salt and store that in the record too, or you could use some of the data you already hold - such as the username:

$query="INSERT INTO ptb_users (id,
        user_id,
        first_name,
        last_name,
        email )
        VALUES('NULL',
        'NULL',
        '".$firstname."',
        '".$lastname."',
        '".$email."',
        MD5('"$user_id.$password."')
        )";

(I am assuming that you've properly escaped all those strings earlier in your code)

I think this is the most clear solution, using an extension method:

public static class HttpRequestMessageExtensions
{
    private const string HttpContext = "MS_HttpContext";
    private const string RemoteEndpointMessage = "System.ServiceModel.Channels.RemoteEndpointMessageProperty";

    public static string GetClientIpAddress(this HttpRequestMessage request)
    {
        if (request.Properties.ContainsKey(HttpContext))
        {
            dynamic ctx = request.Properties[HttpContext];
            if (ctx != null)
            {
                return ctx.Request.UserHostAddress;
            }
        }

        if (request.Properties.ContainsKey(RemoteEndpointMessage))
        {
            dynamic remoteEndpoint = request.Properties[RemoteEndpointMessage];
            if (remoteEndpoint != null)
            {
                return remoteEndpoint.Address;
            }
        }

        return null;
    }
}

So just use it like:

var ipAddress = request.GetClientIpAddress();

We use this in our projects.

You could also use a URI template. If you structured your request into a restful URL Spring could parse the provided value from the url.

HTML

<li>
    <a id="byParameter" 
       class="textLink" href="<c:url value="/mapping/parameter/bar />">By path, method,and
           presence of parameter</a>
</li>

Controller

@RequestMapping(value="/mapping/parameter/{foo}", method=RequestMethod.GET)
public @ResponseBody String byParameter(@PathVariable String foo) {
    //Perform logic with foo
    return "Mapped by path + method + presence of query parameter! (MappingController)";
}

Spring URI Template Documentation

What about 1.1E10, +1, -0, etc? Parsing all possible numbers is trickier than many people think. If you want to include as many numbers are possible you should use the to_number function in a PL/SQL function. From http://www.oracle-developer.net/content/utilities/is_number.sql:

CREATE OR REPLACE FUNCTION is_number (str_in IN VARCHAR2) RETURN NUMBER IS
   n NUMBER;
BEGIN
   n := TO_NUMBER(str_in);
   RETURN 1;
EXCEPTION
   WHEN VALUE_ERROR THEN
      RETURN 0;
END;

Here is a jQuery plugin that does exactly that: http://fixedheadertable.com/

Usage:

$('selector').fixedHeaderTable({ fixedColumn: 1 });

Set the fixedColumn option if you want any number of columns to be also fixed for horizontal scrolling.

EDIT: This example http://www.datatables.net/examples/basic_init/scroll_y.html is much better in my opinion, although with DataTables you'll need to get a better understanding of how it works in general.

EDIT2: For Bootstrap to work with DataTables you need to follow the instructions here: http://datatables.net/blog/Twitter_Bootstrap_2 (I have tested this and it works)- For Bootstrap 3 there's a discussion here: http://datatables.net/forums/discussion/comment/53462 - (I haven't tested this)

Interestingly putting <httpCookies httpOnlyCookies="false"/> doesn't seem to disable httpOnlyCookies in ASP.NET 2.0. Check this article about SessionID and Login Problems With ASP .NET 2.0.

Looks like Microsoft took the decision to not allow you to disable it from the web.config. Check this post on forums.asp.net

You could take your entire server-side model and turn it into a Javascript object by doing the following:

var model = @Html.Raw(Json.Encode(Model));

In your case if you just want the FloorPlanSettings object, simply pass the Encode method that property:

var floorplanSettings = @Html.Raw(Json.Encode(Model.FloorPlanSettings));

See question: How to find an item in a std::vector?

You'll also need to ensure you've implemented a suitable operator==() for your object, if the default one isn't sufficient for a "deep" equality test.

The canonical T-SQL (SqlServer) answer is to use a DELETE with JOIN as such

DELETE o
FROM Orders o
INNER JOIN Customers c
    ON o.CustomerId = c.CustomerId
WHERE c.FirstName = 'sklivvz'

This will delete all orders which have a customer with first name Sklivvz.

Though currently I am still reading the manual, but I think this is very close to C/C++ const pointer. In other words, something like difference between char const* and char*. Compiler also refuses to update content, not only reference reassignment (pointer).

For example, let's say you have this struct. Take care that this is a struct, not a class. AFAIK, classes don't have a concept of immutable state.

import Foundation


struct
AAA
{
    var inner_value1    =   111

    mutating func
    mutatingMethod1()
    {
        inner_value1    =   222
    }
}


let aaa1    =   AAA()
aaa1.mutatingMethod1()      // compile error
aaa1.inner_value1 = 444     // compile error

var aaa2    =   AAA()
aaa2.mutatingMethod1()      // OK
aaa2.inner_value1 = 444     // OK

Because the structs are immutable by default, you need to mark a mutator method with mutating. And because the name aaa1 is constant, you can't call any mutator method on it. This is exactly what we expected on C/C++ pointers.

I believe this is a mechanism to support a kind of const-correctness stuff.

Why cant the address of the node and the "next" node pointed be stored in a table

If we could tabulate this way

node present: (present node addr) (next node address)

node 1: addr1: 0x100 addr2: 0x200 ( no present node address till this point had 0x200)
node 2: addr2: 0x200 addr3: 0x300 ( no present node address till this point had 0x300)
node 3: addr3: 0x300 addr4: 0x400 ( no present node address till this point had 0x400)
node 4: addr4: 0x400 addr5: 0x500 ( no present node address till this point had 0x500)
node 5: addr5: 0x500 addr6: 0x600 ( no present node address till this point had 0x600)
node 6: addr6: 0x600 addr4: 0x400 ( ONE present node address till this point had 0x400)

Hence there is a cycle formed.

var arr1 = [1, 3, 5, 6];
var arr2 = [3, 6, 10, 11, 12];
arr1.concat(arr2.filter(ele => !arr1.includes(ele)));
console.log(arr1);

output :- [1, 3, 5, 6, 10, 11, 12]

With lodash:

const myArr = [ {name: "john", age: 23},
                {name: "john", age: 43},
                {name: "jim", age: 101},
                {name: "bob", age: 67} ];

const johnArr = _.filter(myArr, person => person.name === 'john');
console.log(johnArr)

Vanilla JavaScript:

const myArr = [ {name: "john", age: 23},
                {name: "john", age: 43},
                {name: "jim", age: 101},
                {name: "bob", age: 67} ];

const johnArr = myArr.filter(person => person.name === 'john');
console.log(johnArr);

brew install gradle

To upgrade

One example has always been brought up to me in the context of abstraction; the automatic vs. manual transmission on cars. The manual transmission hides some of the workings of changing gears, but you still have to clutch and shift as a driver. Automatic transmission encapsulates all the details of changing gears, i.e. hides it from you, and it is therefore a higher abstraction of the process of changing gears.

There is no native version of the Redis for windows.(Only some old versions are available)

But you can install latest versions using WSL(Windows Subsystem for Linux), Refer the following blog from the Redis Labs:

https://redislabs.com/blog/redis-on-windows-10

this will point to the <ul> selected by .nav-list. You can use delegation instead!

$('.nav-list').on('click', 'li', function() {
    $('.nav-list li.active').removeClass('active');

});

I used file_get_contents using stream_create_context and it works fine:

            'method' => 'POST',
            'header'=> "Content-type: application/x-www-form-urlencoded\r\n"
                . "Content-Length: " . strlen($postdataArr) . "\r\n"
                . "Cookie: " . $cookies."\r\n"
            'content' => $postdataStr
            )
        );

$context = stream_context_create($context_options);
$HTTPSReq = file_get_contents('https://www.example.com/', false, $context);

So far best solution that I've made:

function convertHtmlToJQueryObject(html){
    var htmlDOMObject = new DOMParser().parseFromString(html, "text/html");
    return $(htmlDOMObject.documentElement);
}

If you add:

<meta http-equiv="content-type" content="text/plain; charset=UTF-8"/>

in the head of the document it will start working as expected:

<script type="text/javascript">
var tableToExcel = (function() {
  var uri = 'data:application/vnd.ms-excel;base64,'
    , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--><meta http-equiv="content-type" content="text/plain; charset=UTF-8"/></head><body><table>{table}</table></body></html>'
    , base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
    , format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
  return function(table, name) {
    if (!table.nodeType) table = document.getElementById(table)
    var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
    window.location.href = uri + base64(format(template, ctx))
  }
})()
</script>

Use queue.rear+1 to get the length of the queue

Python does not have a defined entry point like Java, C, C++, etc. Rather it simply executes a source file line-by-line. The if statement allows you to create a main function which will be executed if your file is loaded as the "Main" module rather than as a library in another module.

To be clear, this means that the Python interpreter starts at the first line of a file and executes it. Executing lines like class Foobar: and def foobar() creates either a class or a function and stores them in memory for later use.

Placing your list view in a Flexible widget may also help,

Flexible( fit: FlexFit.tight, child: _buildYourListWidget(..),)

May be this will help some one. I have my proxy setup in python script but keep getting the error mentioned in the question.

Below is the piece of block which will take my username and password as a constant in the beginning.

   if (use_proxy):
        proxy = req.ProxyHandler({'https': proxy_url})
        auth = req.HTTPBasicAuthHandler()
        opener = req.build_opener(proxy, auth, req.HTTPHandler)
        req.install_opener(opener)

If you are using corporate laptop and if you did not connect to Direct Access or office VPN then the above block will throw error. All you need to do is to connect to your org VPN and then execute your python script.

The extglob shell option gives you more powerful pattern matching in the command line.

You turn it on with shopt -s extglob, and turn it off with shopt -u extglob.

In your example, you would initially do:

$ shopt -s extglob
$ cp !(*Music*) /target_directory

The full available extended globbing operators are (excerpt from man bash):

If the extglob shell option is enabled using the shopt builtin, several extended pattern matching operators are recognized.A pattern-list is a list of one or more patterns separated by a |. Composite patterns may be formed using one or more of the following sub-patterns:

• ?(pattern-list)
  Matches zero or one occurrence of the given patterns
• *(pattern-list)
  Matches zero or more occurrences of the given patterns
• +(pattern-list)
  Matches one or more occurrences of the given patterns
• @(pattern-list)
  Matches one of the given patterns
• !(pattern-list)
  Matches anything except one of the given patterns

So, for example, if you wanted to list all the files in the current directory that are not .c or .h files, you would do:

$ ls -d !(*@(.c|.h))

Of course, normal shell globing works, so the last example could also be written as:

$ ls -d !(*.[ch])

I've just installed 64 bit Node.js v0.12.0 for Windows 8.1 from here. It's about 8MB and since it's an MSI you just double click to launch. It will automatically set up your environment paths etc.

Then to get the command line it's just [Win-Key]+[S] for search and then enter "node.js" as your search phrase.

Choose the Node.js Command Prompt entry NOT the Node.js entry.

Both will given you a command prompt but only the former will actually work. npm is built into that download so then just npm -whatever at prompt.

If you are using C function fgetc then you should check a next character whether it is equal to the new line character or to EOF. For example

unsigned int count = 0;
while ( 1 )
{
   int c = fgetc( FileStream );

   if ( c == EOF || c == '\n' )
   {
      printF( "The length of the line is %u\n", count );
      count = 0;
      if ( c == EOF ) break;
   }
   else
   {
      ++count;
   }
}    

or maybe it would be better to rewrite the code using do-while loop. For example

unsigned int count = 0;
do
{
   int c = fgetc( FileStream );

   if ( c == EOF || c == '\n' )
   {
      printF( "The length of the line is %u\n", count );
      count = 0;
   }
   else
   {
      ++count;
   }
} while ( c != EOF );

Of course you need to insert your own processing of read xgaracters. It is only an example how you could use function fgetc to read lines of a file.

But if the program is written in C++ then it would be much better if you would use std::ifstream and std::string classes and function std::getline to read a whole line.

    echo "US/Central - 10:26 PM (CST)" | sed -n "s/^.*-\s*\(\S*\).*$/\1/p"

-n      suppress printing
s       substitute
^.*     anything at the beginning
-       up until the dash
\s*     any space characters (any whitespace character)
\(      start capture group
\S*     any non-space characters
\)      end capture group
.*$     anything at the end
\1      substitute 1st capture group for everything on line
p       print it

I had the same problem, and here's how it was fixed:

1. My .jsp was calling attributes that I had not yet defined in the servlet.
2. I had two column names that I was passing into an object through ResultSet (getString("columnName")) that didn't match the column names in my database.

I'm not exactly sure which one fixed the problem, but it worked. Also, be sure that you create a new Statement and ResultSet for each table query.

Here is a POSIX function to do that:

url_encode() {
   awk 'BEGIN {
      for (n = 0; n < 125; n++) {
         m[sprintf("%c", n)] = n
      }
      n = 1
      while (1) {
         s = substr(ARGV[1], n, 1)
         if (s == "") {
            break
         }
         t = s ~ /[[:alnum:]_.!~*\47()-]/ ? t s : t sprintf("%%%02X", m[s])
         n++
      }
      print t
   }' "$1"
}

Example:

value=$(url_encode "$2")

If the component is an EJB, then, there shouldn't be a problem injecting an EM.

But....In JBoss 5, the JAX-RS integration isn't great. If you have an EJB, you cannot use scanning and you must manually list in the context-param resteasy.jndi.resource. If you still have scanning on, Resteasy will scan for the resource class and register it as a vanilla JAX-RS service and handle the lifecycle.

This is probably the problem.

Ansible has a version_compare filter since 1.6. You can do something like below in when conditional:

when: ansible_distribution_version | version_compare('12.04', '>=')

This will give you support for major & minor versions comparisons and you can compare versions using operators like:

<, lt, <=, le, >, gt, >=, ge, ==, =, eq, !=, <>, ne

You can find more information about this here: Ansible - Version comparison filters

Otherwise if you have really simple case you can use what @ProfHase85 suggested

In-order to make SQL server send email notification you need to create mail profile from Management, database mail.

1) User Right click to get the mail profile menu and choose configure database mail

2)choose the first open (set up a database mail by following the following tasks) and press next Note: if the SMTP is not configured please refer the the URL below

http://www.symantec.com/business/support/index?page=content&id=TECH86263

3) in the second screen fill the the profile name and add SMTP account, then press next

4) choose the type of mail account ( public or private ) then press next

5) change the parameters that related to the sending mail options, and press next 6) press finish

Now to make SQL server send an email if action X happened you can do that via trigger or job ( This is the common ways not the only ones).

1) you can create Job from SQL server agent, then right click on operators and check mails (fill the your email for example) and press OK after that right click Jobs and choose new job and fill the required info as well as the from steps, name, ...etc and from notification tab select the profile you made.

2) from triggers please refer to the example below.

AS
declare @results varchar(max)
declare @subjectText varchar(max)
declare @databaseName VARCHAR(255)
SET @subjectText = 'your subject'
SET @results = 'your results'
-- write the Trigger JOB
EXEC msdb.dbo.sp_send_dbmail
 @profile_name = 'SQLAlerts',
 @recipients = '[email protected]',
 @body = @results,
 @subject = @subjectText,
 @exclude_query_output = 1 --Suppress 'Mail Queued' message
GO

I wouldn't have thought so.

If you have Visual Studio you could edit them through that. Some versions of Visual Studio has Crystal Reports shipped with them.

If not, you will have to find someone who has Crystal Reports and ask then nicely to amend them for you. Or buy Crystal Reports!

This should work for you:

var movies = _db.Movies.OrderBy(c => c.Category).ThenBy(n => n.Name)

Dataframes have a sort_index method which returns a copy by default. Pass inplace=True to operate in place.

import pandas as pd
df = pd.DataFrame([1, 2, 3, 4, 5], index=[100, 29, 234, 1, 150], columns=['A'])
df.sort_index(inplace=True)
print(df.to_string())

Gives me:

     A
1    4
29   2
100  1
150  5
234  3

If you have a large array and only want to see a subsection of the array you can type this into the watch window;

ptr+100,10

to show a list of the 10 elements starting at ptr[100]. Beware that the displayed array subscripts will start at [0], so you will have to remember that ptr[0] is really ptr[100] and ptr[1] is ptr[101] etc.

Sure, just add & after the command:

read_cfg cfgA &
read_cfg cfgB &
read_cfg cfgC &
wait

all those jobs will then run in the background simultaneously. The optional wait command will then wait for all the jobs to finish.

Each command will run in a separate process, so it's technically not "multithreading", but I believe it solves your problem.

I think it will help somebody.

Oracle 11g provides a PIVOT operation that does what you want.

Oracle 11g solution

select * from
(select id, k, v from _kv) 
pivot(max(v) for k in ('name', 'age', 'gender', 'status')

(Note: I do not have a copy of 11g to test this on so I have not verified its functionality)

I obtained this solution from: http://orafaq.com/wiki/PIVOT

EDIT -- pivot xml option (also Oracle 11g)
Apparently there is also a pivot xml option for when you do not know all the possible column headings that you may need. (see the XML TYPE section near the bottom of the page located at http://www.oracle.com/technetwork/articles/sql/11g-pivot-097235.html)

select * from
(select id, k, v from _kv) 
pivot xml (max(v)
for k in (any) )

(Note: As before I do not have a copy of 11g to test this on so I have not verified its functionality)

Edit2: Changed v in the pivot and pivot xml statements to max(v) since it is supposed to be aggregated as mentioned in one of the comments. I also added the in clause which is not optional for pivot. Of course, having to specify the values in the in clause defeats the goal of having a completely dynamic pivot/crosstab query as was the desire of this question's poster.

First we can just run map() function to get the new array with the results of calling a provided function on every element in the varjson.DATA.

varjson.DATA.map(({name})=>name))

After getting the array of name from the varjson.DATA. We can convert it into a set that will discard all duplicate entries of array and apply spread operator to get a array of unique names:

[...new Set(varjson.DATA.map(({name})=>name))]

const varjson = {_x000D_
  "DATA": [{_x000D_
      "id": 11,_x000D_
      "name": "ajax",_x000D_

      "mark": 63_x000D_
    },_x000D_
    {_x000D_

I hit this issue myself and after much digging I eventually found this bug for ubuntu:

https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/965371

specifically

https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/965371/comments/62

openssl s_client -connect site.tld:443 failed however openssl s_client -tls1 -connect site.tld:443 gave success. In my particular case part of the output included New, TLSv1/SSLv3, Cipher is RC4-MD5 so I set the php context ssl/cipher value appropriately.

FileZilla does not have any command line arguments (nor any other way) that allow an automatic transfer.

Some references:

• FileZilla Client command-line arguments
• https://trac.filezilla-project.org/ticket/2317
• How do I send a file with FileZilla from the command line?

Though you can use any other client that allows automation.

You have not specified, what protocol you are using. FTP or SFTP? You will definitely be able to use WinSCP, as it supports all protocols that FileZilla does (and more).

Combine WinSCP scripting capabilities with Windows Scheduler:

• Automate file transfers to FTP server or SFTP server;
• Schedule file transfers to FTP/SFTP server

A typical WinSCP script for upload (with SFTP) looks like:

open sftp://user:[email protected]/ -hostkey="ssh-rsa 2048 xxxxxxxxxxx...="
put c:\mypdfs\*.pdf /home/user/
close

With FTP, just replace the sftp:// with the ftp:// and remove the -hostkey="..." switch.

Similarly for download: How to schedule an automatic FTP download on Windows?

WinSCP can even generate a script from an imported FileZilla session.

For details, see the guide to FileZilla automation.

(I'm the author of WinSCP)

Another option, if you are using SFTP, is the psftp.exe client from PuTTY suite.

If you are using electron or other chromium frame, you have to include jquery within window explicitly by:

<script language="javascript" type="text/javascript" src="local_path/jquery.js" onload="window.$ = window.jQuery = module.exports;"></script>

I'll offer an analogy to potentially assist in solidifying the conceptual purpose/practicality of object serialization/deserialization.

I imagine object serialization/deserialization in the context of attempting to move an object through a storm drain. The object is essentially "decomposed" or serialized into more modular versions of itself - in this case, a series of bytes - in order to effectively be granted passage through a medium. In a computational sense, we could view the path traveled by the bytes through the storm drain as being akin to bytes traveling through a network. We're transmuting our object in order to conform to a more desirable mode of transportation, or format. The serialized object will typically be stored in a binary file which may later be read from, written to, or both.

Perhaps once our object is able to slip through the drain as a decomposed series of bytes, we may wish to store that representation of the object as binary data within a database or hard disk drive. The main takeaway though, is that with serialization/deserialization, we have the option to let our object remain in it's binary form after being serialized, or "retrieve" the object's original form by performing deserialization.

You can also try System.Diagnostics.Debugger.Launch() method. It helps in taking the debugger pointer to the specified location and you can then debug you code.

Before this step please install your service.exe using the command line of Visual Studio command prompt - installutil projectservice.exe

Then start your service from the Control Panel -> Administrative Tools -> Computer Management ->Service and Application -> Services -> Your Service Name

I assume you are talking about getElementById() returning a reference to an element whilst the others return a node list. Just subscript the nodelist for the others, e.g. document.getElementBytag('table')[4].

Also, elements is only a property of a form (HTMLFormElement), not a table such as in your example.

rand() % ((highestNumber - lowestNumber) + 1) + lowestNumber

Many times if your radio buttons belong to the same radioGroup then

radioButton.setChecked(true)

will not select the radio button properly. So to solve this problem try using your radioGroup.

radioGroup.check(R.id.radioButtonId)

SELECT col1,
  col2
FROM
  (SELECT rownum X,col_table1 FROM table1) T1
INNER JOIN
  (SELECT rownum Y, col_table2 FROM table2) T2
ON T1.X=T2.Y;

You can get the file name, but you can also get the full path, depending what you place between the '%~' and the '0'. Take your pick from

d -- drive
p -- path
n -- file name
x -- extension
f -- full path

E.g., from inside c:\tmp\foo.bat, %~nx0 gives you "foo.bat", whilst %~dpnx0 gives "c:\tmp\foo.bat". Note the pieces are always assembled in canonical order, so if you get cute and try %~xnpd0, you still get "c:\tmp\foo.bat"

In your my.ini, write this:

[mysqld]
sql_mode = "STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

depend on your version. Or:

[mysqld]
sql_mode = ""

or simply remove this: ONLY_FULL_GROUP_BY

Concatenate them with the . operator:

$result = $data1 . " " . $data2;

Or use string interpolation:

$result = "$data1 $data2";

The aim of having the kernel support different ones is that you can try them out without a reboot; you can then run test workloads through the sytsem, measure performance, and then make that the standard one for your app.

On modern server-grade hardware, only the noop one appears to be at all useful. The others seem slower in my tests.

On PostgreSQL (and many other RDBMS), you can do it with regular ALTER TABLE statement:

=> SELECT * FROM Test1;
 id | foo | bar 
----+-----+-----
  2 |   1 |   2

=> ALTER TABLE Test1 RENAME COLUMN foo TO baz;
ALTER TABLE

=> SELECT * FROM Test1;
 id | baz | bar 
----+-----+-----
  2 |   1 |   2

Here are the high-level differences:

Forking

Pros

• Keeps branches separated by user
• Reduces clutter in the primary repository
• Your team process reflects the external contributor process

Cons

• Makes it more difficult to see all of the branches that are active (or inactive, for that matter)
• Collaborating on a branch is trickier (the fork owner needs to add the person as a collaborator)
• You need to understand the concept of multiple remotes in Git
  • Requires additional mental bookkeeping
  • This will make the workflow more difficult for people who aren't super comfortable with Git

Branching

Pros

• Keeps all of the work being done around a project in one place
• All collaborators can push to the same branch to collaborate on it
• There's only one Git remote to deal with

Cons

• Branches that get abandoned can pile up more easily
• Your team contribution process doesn't match the external contributor process
• You need to add team members as contributors before they can branch

Other people have already answered you how to rollback, but you also asked how you could identify the version number of a migration.

• rake db:migrate:status gives a list of your migrations version, name and status (up or down)
• Your can also find the migration file, which contain a timestamp in the filename, that is the version number. Migrations are located in folder: /db/migrate

I have struggled to get a query to return fields from Table 1 that do not exist in Table 2 and tried most of the answers above until I found a very simple way to obtain the results that I wanted.

I set the join properties between table 1 and table 2 to the third setting (3) (All fields from Table 1 and only those records from Table 2 where the joined fields are equal) and placed a Is Null in the criteria field of the query in Table 2 in the field that I was testing for. It works perfectly.

Thanks to all above though.

If strMyString.Contains("Something") or strMyString.Contains("Something2") Then

The error indicates that the compiler thinks you want to do a bitwise OR on a Boolean and a string. Which of course won't work.

The problem is

When a Scanner is closed, it will close its input source if the source implements the Closeable interface.

http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Scanner.html

Thus scan.close() closes System.in.

To fix it you can make

Scanner scan static and do not close it in PromptCustomerQty. Code below works.

public static void main (String[] args) {   

// Create a customer
// Future proofing the possabiltiies of multiple customers
Customer customer = new Customer("Will");

// Create object for each Product
// (Name,Code,Description,Price)
// Initalize Qty at 0
Product Computer = new Product("Computer","PC1003","Basic Computer",399.99); 
Product Monitor = new Product("Monitor","MN1003","LCD Monitor",99.99);
Product Printer = new Product("Printer","PR1003x","Inkjet Printer",54.23);

// Define internal variables 
// ## DONT CHANGE 
ArrayList<Product> ProductList = new ArrayList<Product>(); // List to store Products
String formatString = "%-15s %-10s %-20s %-10s %-10s %n"; // Default format for output

// Add objects to list
ProductList.add(Computer);
ProductList.add(Monitor);
ProductList.add(Printer);

// Ask users for quantities 
PromptCustomerQty(customer, ProductList);

// Ask user for payment method
PromptCustomerPayment(customer);

// Create the header
PrintHeader(customer, formatString);

// Create Body
PrintBody(ProductList, formatString);   
}

static Scanner scan;

public static void PromptCustomerQty(Customer customer, ArrayList<Product> ProductList)               {
// Initiate a Scanner
scan = new Scanner(System.in);

// **** VARIABLES ****
int qty = 0;

// Greet Customer
System.out.println("Hello " + customer.getName());

// Loop through each item and ask for qty desired
for (Product p : ProductList) {

    do {
    // Ask user for qty
    System.out.println("How many would you like for product: " + p.name);
    System.out.print("> ");

    // Get input and set qty for the object
    qty = scan.nextInt();

    }
    while (qty < 0); // Validation

    p.setQty(qty); // Set qty for object
    qty = 0; // Reset count
}

// Cleanup

}

public static void PromptCustomerPayment (Customer customer) {
// Variables
String payment = "";

// Prompt User
do {
System.out.println("Would you like to pay in full? [Yes/No]");
System.out.print("> ");

payment = scan.next();

} while ((!payment.toLowerCase().equals("yes")) && (!payment.toLowerCase().equals("no")));

// Check/set result
if (payment.toLowerCase() == "yes") {
    customer.setPaidInFull(true);
}
else {
    customer.setPaidInFull(false);
}
}

On a side note, you shouldn't use == for String comparision, use .equals instead.

You can use this way either :

Add this line to your recyclerView xml file :

android:nestedScrollingEnabled="false"

Or in java code :

RecyclerView.setNestedScrollingEnabled(false);

Hope this helped .

I used Joe's way to solve this issue :)

decimal argument = 123.456m;
int count = BitConverter.GetBytes(decimal.GetBits(argument)[3])[2];

There's no good reason for 1 to be true and 0 to be false; that's just the way things have always been notated. So from a logical perspective, the function in your API isn't "wrong", per se.

That said, it's normally not advisable to work against the idioms of whatever language or framework you're using without a damn good reason to do so, so whoever wrote this function was probably pretty bone-headed, assuming it's not simply a bug.

I don't know if this is only in the recent versions, but right clicking on the Tables option in the Navigator pane pops up an option called Search Table Data. This opens up a search box where you fill in the search string and hit search.

You do need to select the table you want to search in on the left pane. But if you hold down shift and select like 10 tables at a time, MySql can handle that and return results in seconds.

For anyone that is looking for better options! :)

Try to work with EditText by make it unclickable and unfocusable, also you can display a scrollbar and delete the EditText's underbar.
Here is an example:

<EditText
android:id="@+id/my_edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_parent"
android:inputType="textMultiLine"                   <!-- multiline -->
android:clickable="false"                         <!-- unclickable -->
android:focusable="false"                         <!-- unfocusable -->
android:scrollbars="vertical"     <!-- enable scrolling vertically -->
android:background="@android:color/transparent"   <!-- hide the underbar of EditText -->
/>  

Hope this helps :)

If you type:

if { number.value.length!= 10}...     

It will sure work because the value is the quantity which will be driven from the object.

You can use Notification and NotificationManager to display the notification you want. You can then customize the sound you want to play with your notification.

If you really need single quotes, apostrophes, you can use

html    | numeric | hex
‘ | ‘  | ‘ // for the left/beginning single-quote and
’ | ’  | ’ // for the right/ending single-quote

I find "per container per bean" difficult to apprehend. I would say "one bean per bean id in a container".Lets have an example to understand it. We have a bean class Sample. I have defined two beans from this class in bean definition, like:

<bean id="id1" class="com.example.Sample" scope="singleton">
        <property name="name" value="James Bond 001"/>    
</bean>    
<bean id="id7" class="com.example.Sample" scope="singleton">
        <property name="name" value="James Bond 007"/>    
</bean>

So when ever I try to get the bean with id "id1",the spring container will create one bean, cache it and return same bean where ever refered with id1. If I try to get it with id7, another bean will be created from Sample class, same will be cached and returned each time you referred that with id7.

This is unlikely with Singleton pattern. In Singlton pattern one object per class loader is created always. However in Spring, making the scope as Singleton does not restrict the container from creating many instances from that class. It just restricts new object creation for the same ID again, returning previously created object when an object is requested for the same id. Reference

Thanks, I could not used the page directive because I have to set a different content type according to some URL parameter. I will paste my code here since it's something quite common with JSON:

    <%
        String callback = request.getParameter("callback");
        response.setCharacterEncoding("UTF-8");
        if (callback != null) {
            // Equivalent to: <@page contentType="text/javascript" pageEncoding="UTF-8">
            response.setContentType("text/javascript");
        } else {
            // Equivalent to: <@page contentType="application/json" pageEncoding="UTF-8">
            response.setContentType("application/json");
        }

        [...]

        String output = "";

        if (callback != null) {
            output += callback + "(";
        }

        output += jsonObj.toString();

        if (callback != null) {
            output += ");";
        }
    %>
    <%=output %>

When callback is supplied, returns:

    callback({...JSON stuff...});

with content-type "text/javascript"

When callback is NOT supplied, returns:

    {...JSON stuff...}

with content-type "application/json"

Short and flexible with support for negative values, although by using two comma expressions :)

function timeUnitsBetween(startDate, endDate) {
  let delta = Math.abs(endDate - startDate) / 1000;
  const isNegative = startDate > endDate ? -1 : 1;
  return [
    ['days', 24 * 60 * 60],
    ['hours', 60 * 60],
    ['minutes', 60],
    ['seconds', 1]
  ].reduce((acc, [key, value]) => (acc[key] = Math.floor(delta / value) * isNegative, delta -= acc[key] * isNegative * value, acc), {});
}

Example:

timeUnitsBetween(new Date("2019-02-11T02:12:03+00:00"), new Date("2019-02-11T01:00:00+00:00"));
// { days: -0, hours: -1, minutes: -12, seconds: -3 }

To get current user info:

jQuery.ajax({
    url: _spPageContextInfo.webServerRelativeUrl + "/_api/web/currentuser",
    type: "GET",
    headers: { "Accept": "application/json;odata=verbose" }
}).done(function( data ){
    console.log( data );
    console.log( data.d.Title );
}).fail(function(){
    console.log( failed );
});

input:

hello world

String A = hello;
String B = world;
System.out.println(A.toUpperCase().charAt(0)+A.substring(1) + " " + B.toUpperCase().charAt(0)+B.substring(1));

Output:

The 2018 ES6+ ANSWER IS:

    const arr = [1, 2, 3];

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

An efficient way to loop over an Array is the built-in array method .map()

For a 1-dimensional array it would look like this:

function HandleOneElement( Cuby ) {
   Cuby.dimension
   Cuby.position_x
   ...
}
cubes.map(HandleOneElement) ; // the map function will pass each element

for 2-dimensional array:

cubes.map( function( cubeRow ) { cubeRow.map( HandleOneElement ) } )

for an n-dimensional array of any form:

Function.prototype.ArrayFunction = function(param) {
  if (param instanceof Array) {
    return param.map( Function.prototype.ArrayFunction, this ) ;
  }
  else return (this)(param) ;
}
HandleOneElement.ArrayFunction(cubes) ;

On windows, you must set a variable to specify proxy settings, download the vagrant-proxyconf plugin: (replace {PROXY_SCHEME}(http:// or https://), {PROXY_IP} and {PROXY_PORT} by the right values)

set http_proxy={PROXY_SCHEME}{PROXY_IP}:{PROXY_PORT}
set https_proxy={PROXY_SCHEME}{PROXY_IP}:{PROXY_PORT}

After that, you can add the plugin to hardcode your proxy settings in the vagrant file

vagrant plugin install vagrant-proxyconf --plugin-source http://rubygems.org

and then you can provide config.proxy.xxx settings in your Vagrantfile to be independent against environment settings variables

To fix this problem on specific page need to set some validation settings when page loading. Write code below in Page_Load() method:

protected void Page_Load(object sender, EventArgs e)
    {
        ValidationSettings.UnobtrusiveValidationMode = UnobtrusiveValidationMode.None;
    }

Its work for me in .NET 4.5

You just need to install Java. It did work after installing Java version 8, using this command : sudo apt install openjdk-8-jre-headless

Use Services

1. Windows -> Services
2. check your PostgresSQL is started or in running state. ( If it's not then start your services for PostgresSQL).
3. Close services and check again with your PostgresSQL.

This will start PostgresSQL servers as normal.

As you say, local variables and references are stored on the stack. When a method returns, the stack pointer is simply moved back to where it was before the method started, that is, all local data is "removed from the stack". Therefore, there is no garbage collection needed on the stack, that only happens in the heap.

To answer your specific questions:

• See this question on how to increase the stack size.
• You can limit the stack growth by:
  • grouping many local variables in an object: that object will be stored in the heap and only the reference is stored on the stack
  • limit the number of nested function calls (typically by not using recursion)
• For windows, the default stack size is 320k for 32bit and 1024k for 64bit, see this link.

• The main entry point of the HttpClient API is the HttpClient interface.
• The most essential function of HttpClient is to execute HTTP methods.
• Execution of an HTTP method involves one or several HTTP request / HTTP response exchanges, usually handled internally by HttpClient.

• CloseableHttpClient is an abstract class which is the base implementation of HttpClient that also implements java.io.Closeable.

• Here is an example of request execution process in its simplest form:

  CloseableHttpClient httpclient = HttpClients.createDefault();
  HttpGet httpget = new HttpGet("http://localhost/");
  CloseableHttpResponse response = httpclient.execute(httpget);
  try {
      //do something
  } finally {
      response.close();
  }

• HttpClient resource deallocation: When an instance CloseableHttpClient is no longer needed and is about to go out of scope the connection manager associated with it must be shut down by calling the CloseableHttpClient#close() method.

  CloseableHttpClient httpclient = HttpClients.createDefault();
  try {
      //do something
  } finally {
      httpclient.close();
  }

see the Reference to learn fundamentals.

@Scadge Since Java 7, Use of try-with-resources statement ensures that each resource is closed at the end of the statement. It can be used both for the client and for each response

try(CloseableHttpClient httpclient = HttpClients.createDefault()){

    // e.g. do this many times
    try (CloseableHttpResponse response = httpclient.execute(httpget)) {
    //do something
    }

    //do something else with httpclient here
}

Missing square brackets around input property may cause this error. For example:

Component Foo {
    @Input()
    bars: BarType[];
}

Correct:

<app-foo [bars]="smth"></app-foo>

Incorrect (triggering error):

<app-foo bars="smth"></app-foo>

If you're testing for all zeros to avoid a warning on another numpy function then wrapping the line in a try, except block will save having to do the test for zeros before the operation you're interested in i.e.

try: # removes output noise for empty slice 
    mean = np.mean(array)
except:
    mean = 0

The above solutions didn't work for me for classes with background images somehow. What I did was I create a default class (the one you need in else) and set class='defaultClass' and then the ng-class="{class1:abc,class2:xyz}"

<span class="booking_warning" ng-class="{ process_success: booking.bookingStatus == 'BOOKING_COMPLETED' || booking.bookingStatus == 'BOOKING_PROCESSED', booking_info: booking.bookingStatus == 'INSTANT_BOOKING_REQUEST_RECEIVED' || booking.bookingStatus == 'BOOKING_PENDING'}"> <strong>{{booking.bookingStatus}}</strong> </span>

P.S: The classes that are in condition should override the default class i.e marked as !important

You could try the following:

import matplotlib.pyplot as plt
import numpy as np

def plot_figures(figures, nrows = 1, ncols=1):
    """Plot a dictionary of figures.

    Parameters
    ----------
    figures : <title, figure> dictionary
    ncols : number of columns of subplots wanted in the display
    nrows : number of rows of subplots wanted in the figure
    """

    fig, axeslist = plt.subplots(ncols=ncols, nrows=nrows)
    for ind,title in zip(range(len(figures)), figures):
        axeslist.ravel()[ind].imshow(figures[title], cmap=plt.jet())
        axeslist.ravel()[ind].set_title(title)
        axeslist.ravel()[ind].set_axis_off()
    plt.tight_layout() # optional



# generation of a dictionary of (title, images)
number_of_im = 20
w=10
h=10
figures = {'im'+str(i): np.random.randint(10, size=(h,w)) for i in range(number_of_im)}

# plot of the images in a figure, with 5 rows and 4 columns
plot_figures(figures, 5, 4)

plt.show()

However, this is basically just copy and paste from here: Multiple figures in a single window for which reason this post should be considered to be a duplicate.

I hope this helps.

does your proxy require you to authenticate? because if it does, you might want you configure your proxy like this.

placeholder names. username is a placeholder for your actual username. password is a placeholder for your actual password. proxy.company.com is a placeholder for your actualy proxy *port" is your actualy port the proxy goes through. its usualy 8080

npm config set proxy "http://username:[email protected]:port"

This fixed version of code above remember the last element of CVS row ;-)

(tested with a CSV file with 5400 rows and 26 elements by row)

   public static string[] CSVRowToStringArray(string r, char fieldSep = ',', char stringSep = '\"')  {
            bool bolQuote = false;
            StringBuilder bld = new StringBuilder();
            List<string> retAry = new List<string>();

            foreach (char c in r.ToCharArray())
                if ((c == fieldSep && !bolQuote))
                {
                    retAry.Add(bld.ToString());
                    bld.Clear();
                }
                else
                    if (c == stringSep)
                        bolQuote = !bolQuote;
                    else
                        bld.Append(c);

            /* to solve the last element problem */
            retAry.Add(bld.ToString()); /* added this line */
            return retAry.ToArray();
        }

You should create a structure that represents JSON keys (in case if you exactly know it) and then you can easily deserialize JSON string into your structure. In my examle I've deserialized a response from Google Cloud Message server:

class templateResponse
{
    public String multicast_id;
    public String success;
    public String failure;
    public String canonical_ids;
    public Result[] results;

    public class Result
    {
        public String message_id;
        public String registration_id;
        public String error;
    };
}

incoming JSON was:

"\"multicast_id\":7400896764380883211,\"success\":1,\"failure\":0,\"canonical_ids\":0,\"results\":[{\"message_id\":\"0:1351777805148960%39895cf0f9fd7ecd\"}]}"

So, use

templateResponse result = new JavaScriptSerializer().Deserialize<templateResponse>(json);

and you will get deserialized result object

Online .htaccess rewrite testing

I found this Googling for RegEx help, it saved me a lot of time from having to upload new .htaccess files every time I make a small modification.

from the site:

htaccess tester

To test your htaccess rewrite rules, simply fill in the url that you're applying the rules to, place the contents of your htaccess on the larger input area and press "Check Now" button.

Anything after Application.Run( ) will only be executed when the main form closes.

What you could do is handle the VisibleChanged event as follows:

static Form1 form1;
static Form2 form2;

static void Main()
{

    Application.EnableVisualStyles();
    Application.SetCompatibleTextRenderingDefault(false);
    form2 = new Form2();
    form1 = new Form1();
    form2.Hide();
    form1.VisibleChanged += OnForm1Changed;
    Application.Run(form1);

}

static void OnForm1Changed( object sender, EventArgs args )
{
    if ( !form1.Visible )
    {
        form2.Show( );
    }
}

From the docs, the recommended way of getting a timezone aware datetime object from seconds since epoch is:

Python 3:

from datetime import datetime, timezone
datetime.fromtimestamp(timestamp, timezone.utc)

Python 2, using pytz:

from datetime import datetime
import pytz
datetime.fromtimestamp(timestamp, pytz.utc)

As other people have already noted, feature detection is preferred over checking for a specific browser. One reason is that the user agent string can be altered. Another reason is that the string may change and break your code in newer versions.

If you still want to do it and test for any Safari version, I'd suggest using this

var isSafari = navigator.vendor && navigator.vendor.indexOf('Apple') > -1 &&
               navigator.userAgent &&
               navigator.userAgent.indexOf('CriOS') == -1 &&
               navigator.userAgent.indexOf('FxiOS') == -1;

This will work with any version of Safari across all devices: Mac, iPhone, iPod, iPad.

Edit

To test in your current browser: https://jsfiddle.net/j5hgcbm2/

Edit 2

Updated according to Chrome docs to detect Chrome on iOS correctly

It's worth noting that all Browsers on iOS are just wrappers for Safari and use the same engine. See bfred.it's comment on his own answer in this thread.

Edit 3

Updated according to Firefox docs to detect Firefox on iOS correctly

I was getting the same problem on Spring Tool Suite 3.2 and changed the version of jstl to 1.2 (from 1.1.2) manually when adding it to the dependency list, and the error got disappeared.

You should also consider using libraries to do that: they allow limiting and much more:

• FineUploader. Demo using validation.itemLimit as of 5.16.2:

  var restrictedUploader = new qq.FineUploader({
      validation: {
          itemLimit: 3,
      }
  });
  

• bluimp's jQuery File Upload Plugin. Usage: jquery file upload restricting number of files using maxNumberOfFiles as of v9.22.0:

  $('#fileuploadbasic').fileupload({
    maxNumberOfFiles: 6
  });
  

They are also available at https://cdnjs.com/

Many thanks to Ramesh. I used a version of his simple code to pull a string out a database and use it to do boolean operations in my code.

x is a number like 1500 or 2100 or whatever.

function would be a stored evaluation like x > 1400 and x < 1600

function = relation[0].Replace("and","&&").Replace("x",x);

DataTable f_dt = new DataTable();
var f_var = f_dt.Compute(function,"");

if (bool.Parse(f_var.ToString()) { do stuff  }

Your code doesn't get the UTF-8 into memory as you read it back into a string again, so its no longer in UTF-8, but back in UTF-16 (though ideally its best to consider strings at a higher level than any encoding, except when forced to do so).

To get the actual UTF-8 octets you could use:

var serializer = new XmlSerializer(typeof(SomeSerializableObject));

var memoryStream = new MemoryStream();
var streamWriter = new StreamWriter(memoryStream, System.Text.Encoding.UTF8);

serializer.Serialize(streamWriter, entry);

byte[] utf8EncodedXml = memoryStream.ToArray();

I've left out the same disposal you've left. I slightly favour the following (with normal disposal left in):

var serializer = new XmlSerializer(typeof(SomeSerializableObject));
using(var memStm = new MemoryStream())
using(var  xw = XmlWriter.Create(memStm))
{
  serializer.Serialize(xw, entry);
  var utf8 = memStm.ToArray();
}

Which is much the same amount of complexity, but does show that at every stage there is a reasonable choice to do something else, the most pressing of which is to serialise to somewhere other than to memory, such as to a file, TCP/IP stream, database, etc. All in all, it's not really that verbose.

Simple solution would be as below. This is improvement of solution from vale.

private void dgMapTable_SelectionChanged(object sender, EventArgs e) 
{
    int active_map=0;
    if(dgMapTable.SelectedRows.Count>0)
        active_map = dgMapTable.SelectedRows[0].Index;
    // User code if required Process_ROW(active_map);
}

Note for other reader, for above code to work FullRowSelect selection mode for datagridview should be used. You may extend this to give message if more than two rows selected.

Rather than ask for details to a specific solution, I recommend describing the problem you face; I think you'll get better answers. I say this since there's almost certainly a better way to do whatever it is you're trying to do. Accessing variable names in this way is not commonly needed to solve problems in any language.

That said, all of your variable names are already in dictionaries which are accessible through the built-in functions locals and globals. Use the correct one for the scope you are inspecting.

One of the few common idioms for inspecting these dictionaries is for easy string interpolation:

>>> first = 'John'
>>> last = 'Doe'
>>> print '%(first)s %(last)s' % globals()
John Doe

This sort of thing tends to be a bit more readable than the alternatives even though it requires inspecting variables by name.

You have to close that application first. There is no way to delete it, if it's used by some application.

UnLock IT is a neat utility that helps you to take control of any file or folder when it is locked by some application or system. For every locked resource, you get a list of locking processes and can unlock it by terminating those processes. EMCO Unlock IT offers Windows Explorer integration that allows unlocking files and folders by one click in the context menu.

There's also Unlocker (not recommended, see Warning below), which is a free tool which helps locate any file locking handles running, and give you the option to turn it off. Then you can go ahead and do anything you want with those files.

Warning: The installer includes a lot of undesirable stuff. You're almost certainly better off with UnLock IT.

PATTERN FORMAT

• A blank line matches no files, so it can serve as a separator for readability.

• A line starting with # serves as a comment.

• An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again. If a negated pattern matches, this will override lower precedence patterns sources.

• If the pattern ends with a slash, it is removed for the purpose of the following description, but it would only find a match with a directory. In other words, foo/ will match a directory foo and paths underneath it, but will not match a regular file or a symbolic link foo (this is consistent with the way how pathspec works in general in git).

• If the pattern does not contain a slash /, git treats it as a shell glob pattern and checks for a match against the pathname relative to the location of the .gitignore file (relative to the toplevel of the work tree if not from a .gitignore file).

• Otherwise, git treats the pattern as a shell glob suitable for consumption by fnmatch(3) with the FNM_PATHNAME flag: wildcards in the pattern will not match a / in the pathname. For example, Documentation/*.html matches Documentation/git.html but not Documentation/ppc/ppc.html or tools/perf/Documentation/perf.html.

• A leading slash matches the beginning of the pathname. For example, /*.c matches cat-file.c but not mozilla-sha1/sha1.c.

Add this dependency

I found this here:

On windows (win xp), the parent process will not finish until the longtask.py has finished its work. It is not what you want in CGI-script. The problem is not specific to Python, in PHP community the problems are the same.

The solution is to pass DETACHED_PROCESS Process Creation Flag to the underlying CreateProcess function in win API. If you happen to have installed pywin32 you can import the flag from the win32process module, otherwise you should define it yourself:

DETACHED_PROCESS = 0x00000008

pid = subprocess.Popen([sys.executable, "longtask.py"],
                       creationflags=DETACHED_PROCESS).pid

Setting a custom button using constraint:

let buttonWidth = CGFloat(30)
let buttonHeight = CGFloat(30)

let button = UIButton(type: .custom)
button.setImage(UIImage(named: "img name"), for: .normal)
button.addTarget(self, action: #selector(buttonTapped(sender:)), for: .touchUpInside)
button.widthAnchor.constraint(equalToConstant: buttonWidth).isActive = true
button.heightAnchor.constraint(equalToConstant: buttonHeight).isActive = true

self.navigationItem.rightBarButtonItem = UIBarButtonItem.init(customView: button)

If you know the position, why not just get the index from that?

Then use .loc:

df.loc[index, 'COL_NAME'] = x

By Using underscore.js

var arr = [{id:1,name:'a'},{id:2,name:'b'},{id:3,name:'c'}];

var resultArr = _.reject(arr,{id:3});

console.log(resultArr);

The result will be :: [{id:1name:'a'},{id:2,name:'c'}]

In my case, the warning occurred because of just the regular type of boolean indexing -- because the series had only np.nan. Demonstration (pandas 1.0.3):

>>> import pandas as pd
>>> import numpy as np
>>> pd.Series([np.nan, 'Hi']) == 'Hi'
0    False
1     True
>>> pd.Series([np.nan, np.nan]) == 'Hi'
~/anaconda3/envs/ms3/lib/python3.7/site-packages/pandas/core/ops/array_ops.py:255: FutureWarning: elementwise comparison failed; returning scalar instead, but in the future will perform elementwise comparison
  res_values = method(rvalues)
0    False
1    False

I think with pandas 1.0 they really want you to use the new 'string' datatype which allows for pd.NA values:

>>> pd.Series([pd.NA, pd.NA]) == 'Hi'
0    False
1    False
>>> pd.Series([np.nan, np.nan], dtype='string') == 'Hi'
0    <NA>
1    <NA>
>>> (pd.Series([np.nan, np.nan], dtype='string') == 'Hi').fillna(False)
0    False
1    False

Don't love at which point they tinkered with every-day functionality such as boolean indexing.

To set value in the ComboBox

cmbEmployeeStatus.Text="Something";

This should work fine (using .text():

$("#toptitle").text("New word");

Here is a simple example of adding an image to a JFrame:

frame.add(new JLabel(new ImageIcon("Path/To/Your/Image.png")));

print type(variable_name)

I also highly recommend the IPython interactive interpreter when dealing with questions like this. It lets you type variable_name? and will return a whole list of information about the object including the type and the doc string for the type.

e.g.

In [9]: var = 123

In [10]: var?
Type:       int
Base Class: <type 'int'>
String Form:    123
Namespace:  Interactive
Docstring:
    int(x[, base]) -> integer

Convert a string or number to an integer, if possible. A floating point argument will be truncated towards zero (this does not include a string representation of a floating point number!) When converting a string, use the optional base. It is an error to supply a base when converting a non-string. If the argument is outside the integer range a long object will be returned instead.

Take a look at this. a clean and simple solution using jQuery.

    <script type="text/javascript">

    $(function() {

          $("#goy").text('The dog is in its shed');

I tried a number of the above suggestions but got an ILLEGAL character warning in Chrome code inspector. The following worked for me (only tested in Chrome though!)

alert('stuff on line 1\\nstuff on line 2);

comes out like...

stuff on line 1
stuff on line 2

NOTE the double backslash!!...this seems to be important!

I would use something similar to this:

DECLARE @DATEFROM AS DATETIME
DECLARE @DATETO AS DATETIME
DECLARE @HOLDER TABLE(DATE DATETIME)

SET @DATEFROM = '2010-08-10'
SET @DATETO = '2010-09-11'

INSERT INTO
    @HOLDER
        (DATE)
VALUES
    (@DATEFROM)

WHILE @DATEFROM < @DATETO
BEGIN

    SELECT @DATEFROM = DATEADD(D, 1, @DATEFROM)
    INSERT 
    INTO
        @HOLDER
            (DATE)
    VALUES
        (@DATEFROM)
END

SELECT 
    DATE
FROM
    @HOLDER

Then the @HOLDER Variable table holds all the dates incremented by day between those two dates, ready to join at your hearts content.

The problem is what happens when you get NumberFormatexception thrown? You print it and return nothing.

Note: You don't need to catch and throw an Exception back. Usually it is done to wrap it or print stack trace and ignore for example.

catch(RangeException e) {
     throw e;
}

In SQL Developer you can right-click on the package body then select RUN. The 'Run PL/SQL' window will let you edit the PL/SQL Block. Clicking OK will give you a window pane titled 'Output Variables - Log' with an output variables tab. You can select your output variables on the left and the result is shown on the right side. Very handy and fast.

I've used Rapid with T-SQL and I think there was something similiar to this.

Writing your own delcare-begin-end script where you loop through the cursor, as with DCookie's example, is always a good exercise to do every now and then. It will work with anything and you will know that your code works.

String str = "129018";
StringBuilder sb = new StringBuilder();

for (int toPrepend=10-str.length(); toPrepend>0; toPrepend--) {
    sb.append('0');
}

sb.append(str);
String result = sb.toString();

First Program with comments

#include <stdio.h>

int main(){
    int *ptr;             //Create a pointer that points to random memory address

    *ptr = 20;            //Dereference that pointer, 
                          // and assign a value to random memory address.
                          //Depending on external (not inside your program) state
                          // this will either crash or SILENTLY CORRUPT another 
                          // data structure in your program.  

    printf("%d", *ptr);   //Print contents of same random memory address
                          // May or may not crash, depending on who owns this address

    return 0;             
}

Second Program with comments

#include <stdio.h>

int main(){
    int *ptr;              //Create pointer to random memory address

    int q = 50;            //Create local variable with contents int 50

    ptr = &q;              //Update address targeted by above created pointer to point
                           // to local variable your program properly created

    printf("%d", *ptr);    //Happily print the contents of said local variable (q)
    return 0;
}

The key is you cannot use a pointer until you know it is assigned to an address that you yourself have managed, either by pointing it at another variable you created or to the result of a malloc call.

Using it before is creating code that depends on uninitialized memory which will at best crash but at worst work sometimes, because the random memory address happens to be inside the memory space your program already owns. God help you if it overwrites a data structure you are using elsewhere in your program.

myArray[j.x] is logically incorrect.

Use (myArray[j].x); instead

for (var j = 0; j < myArray.length; j++){
  console.log(myArray[j].x);
}

Your "listen" directives are wrong. See this page: http://nginx.org/en/docs/http/server_names.html.

They should be

server {
    listen      80;
    server_name www.domain1.com;
    root /var/www/domain1;
}

server {
    listen       80;
    server_name www.domain2.com;
    root /var/www/domain2;
}

Note, I have only included the relevant lines. Everything else looked okay but I just deleted it for clarity. To test it you might want to try serving a text file from each server first before actually serving php. That's why I left the 'root' directive in there.

you can download and install db2client and looking for - db2jcc.jar - db2jcc_license_cisuz.jar - db2jcc_license_cu.jar - and etc. at C:\Program Files (x86)\IBM\SQLLIB\java

Had the same error initially. so.. pre-installed git and node.js and later installed Aptana, which installed perfectly. Rajeeva.

Difference between null & empty string. For example: you have a variable named x. If you write in JS,

var x = "";

this means that you have assigned a value which is empty string (length is 0). Actually this is like something but which is feel of nothing :) On the other hand,

var y = null;

this means you've not assigned a value to y that clearly said by writing null to y at the time of declaration. If you write y.length; it will throw an error which indicates that no value assigned to y and as a result can't read length of y.

I found the solution below on this page:

x="test\ me"  
eval cd $x

A combination of \ in a double-quoted text constant and an eval before cd makes it work like a charm!

It's pretty simple

#Opening file
f= open('sample.txt')
#reading everything in file
r=f.read()
#reading at particular index
r=f.read(1)
#print
print(r)

Another python3 solution uses tuple unpacking with the "*" character:

first, *_, last = range(1, 10)

There are several situations that will give you this particular error. In the case of the OP there was a value defined explicitly as a string. So I have to assume that maybe this came from a dropdown, or web service or raw JSON string.

In that case a simple cast <Fruit> fruitString or fruitString as Fruit is the only solution (see other answers). You wouldn't ever be able to improve on this at compile time. [Edit: See my other answer about <const>] !

However it's very easy to run into this same error when using constants in your code that aren't ever intended to be of type string. My answer focuses on that second scenario:

First of all: Why are 'magic' string constants often better than an enum?

• I like the way a string constant looks vs. an enum - it's compact and 'javascripty'
• Makes more sense if the component you're using already uses string constants.
• Having to import an 'enum type' just to get an enumeration value can be troublesome in itself
• Whatever I do I want it to be compile safe so if I add remove a valid value from the union type, or mistype it then it MUST give a compile error.

Fortunately when you define:

export type FieldErrorType = 'none' | 'missing' | 'invalid'

...you're actually defining a union of types where 'missing' is actually a type!

I often run into the 'not assignable' error if I have a string like 'banana' in my typescript and the compiler thinks I meant it as a string, whereas I really wanted it to be of type banana. How smart the compiler is able to be will depend on the structure of your code.

Here's an example of when I got this error today:

// this gives me the error 'string is not assignable to type FieldErrorType'
fieldErrors: [ { fieldName: 'number', error: 'invalid' } ]

As soon as I found out that 'invalid' or 'banana' could be either a type or a string I realized I could just assert a string into that type. Essentially cast it to itself, and tell the compiler no I don't want this to be a string!

// so this gives no error, and I don't need to import the union type too
fieldErrors: [ { fieldName: 'number', error: <'invalid'> 'invalid' } ]

So what's wrong with just 'casting' to FieldErrorType (or Fruit)

// why not do this?
fieldErrors: [ { fieldName: 'number', error: <FieldErrorType> 'invalid' } ]

It's not compile time safe:

 <FieldErrorType> 'invalidddd';  // COMPILER ALLOWS THIS - NOT GOOD!
 <FieldErrorType> 'dog';         // COMPILER ALLOWS THIS - NOT GOOD!
 'dog' as FieldErrorType;        // COMPILER ALLOWS THIS - NOT GOOD!

Why? This is typescript so <FieldErrorType> is an assertion and you are telling the compiler a dog is a FieldErrorType! And the compiler will allow it!

BUT if you do the following, then the compiler will convert the string to a type

 <'invalid'> 'invalid';     // THIS IS OK  - GOOD
 <'banana'> 'banana';       // THIS IS OK  - GOOD
 <'invalid'> 'invalidddd';  // ERROR       - GOOD
 <'dog'> 'dog';             // ERROR       - GOOD

Just watch out for stupid typos like this:

 <'banana'> 'banan';    // PROBABLY WILL BECOME RUNTIME ERROR - YOUR OWN FAULT!

Another way to solve the problem is by casting the parent object:

My definitions were as follows:

export type FieldName = 'number' | 'expirationDate' | 'cvv'; export type FieldError = 'none' | 'missing' | 'invalid'; export type FieldErrorType = { field: FieldName, error: FieldError };

Let's say we get an error with this (the string not assignable error):

  fieldErrors: [ { field: 'number', error: 'invalid' } ]

We can 'assert' the whole object as a FieldErrorType like this:

  fieldErrors: [ <FieldErrorType> { field: 'number', error: 'invalid' } ]

Then we avoid having to do <'invalid'> 'invalid'.

But what about typos? Doesn't <FieldErrorType> just assert whatever is on the right to be of that type. Not in this case - fortunately the compiler WILL complain if you do this, because it's clever enough to know it's impossible:

  fieldErrors: [ <FieldErrorType> { field: 'number', error: 'dog' } ]

As I understand the .complete property is non-standard. It may not be universal... I notice it seem to work differently in Firefox verses IE. I am loading a number of images in javascript then checking if complete. In Firefox, this seems to work great. In IE, it doesn't because the images appear to be loading on another thread. It works only if I put a delay between my assignment to image.src and when I check the image.complete property.

Using image.onload and image.onerror isn't working for me, either, because I need to pass a parameter to know which image I am talking about when the function is called. Any way of doing that seems to fail because it actually seems to pass the same function, not different instances of the same function. So the value I pass into it to identify the image always ends up being the last value in the loop. I cannot think of any way around this problem.

On Safari and Chrome, I am seeing the image.complete true and the naturalWidth set even when the error console shows a 404 for that image... and I intentionally removed that image to test this. But the above works well for Firefox and IE.

I use Doctrine\ORM\Tools\Pagination\Paginator for this, and it works perfectly (doctrine 2.2).

$dql = "SELECT p, c FROM BlogPost p JOIN p.comments c";
$query = $entityManager->createQuery($dql)
                       ->setFirstResult(0)
                       ->setMaxResults(10);

$paginator = new Paginator($query, $fetchJoinCollection = true);

Use the string.equals(Object other) function to compare strings, not the == operator.

The function checks the actual contents of the string, the == operator checks whether the references to the objects are equal. Note that string constants are usually "interned" such that two constants with the same value can actually be compared with ==, but it's better not to rely on that.

if (usuario.equals(datos[0])) {
    ...
}

NB: the compare is done on 'usuario' because that's guaranteed non-null in your code, although you should still check that you've actually got some tokens in the datos array otherwise you'll get an array-out-of-bounds exception.

From the jQuery :input selector page:

Because :input is a jQuery extension and not part of the CSS specification, queries using :input cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :input to select elements, first select the elements using a pure CSS selector, then use .filter(":input").

This is the best choice.

$('#new_user_form *').filter(':input').each(function(){
    //your code here
});

Implicitly wait and Thread.sleep Both are used for synchronization only..but the difference is we can use Implicitly wait for entire program but Thread.sleep will works for that single code only..Here my suggestion is use Implicitly wait once in the program when every time your Webpage will get refreshed means use Thread.sleep at that time..it will much Better :)

Here is My Code :

package beckyOwnProjects;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.interactions.Actions;

public class Flip {

    public static void main(String[] args) throws InterruptedException {
        WebDriver driver=new FirefoxDriver();
        driver.manage().window().maximize();
        driver.manage().timeouts().implicitlyWait(2, TimeUnit.MINUTES);
        driver.get("https://www.flipkart.com");
    WebElement ele=driver.findElement(By.cssSelector(".menu-text.fk-inline-block"));
    Actions act=new Actions(driver);
    Thread.sleep(5000);
    act.moveToElement(ele).perform();
    }

}

If you can avoid the need for concurrent writes to a single file, it sounds like you do not need a database to store the chat messages.

Just append the conversation to a text file (1 file per user\conversation). and have a directory/ file structure

Here's a simplified view of the file structure:

chat-1-bob.txt
        201101011029, hi
        201101011030, fine thanks.

chat-1-jen.txt
        201101011030, how are you?
        201101011035, have you spoken to bill recently?

chat-2-bob.txt
        201101021200, hi
        201101021222, about 12:22
chat-2-bill.txt
        201101021201, Hey Bob,
        201101021203, what time do you call this?

You would then only need to store the userid, conversation id (guid ?) & a reference to the file name.

I think you will find it hard to get a more simple scaleable solution.

You can use LOAD_FILE to get the data too see: http://dev.mysql.com/doc/refman/5.0/en/string-functions.html

If you have a requirement to rebuild a conversation you will need to put a value (date time) alongside your sent chat message (in the file) to allow you to merge & sort the files, but at this point it is probably a good idea to consider using a database.

try this.. I had it too but now it solved in XP..

On windows, you can use PuttyGen to load the private key file, remove the passphrase and then overwrite the existing private key file.

Doing this fixed my issue

<script type="text/javascript">
    function SubmitFrm(){
        var Searchtxt = document.getElementById("txtSearch").value;
        window.location = "http://www.mysite.com/search/?Query=" + Searchtxt;
    }
</script>

I changed .value(); to .value; taking out the ()

I did not change anything in my text field or submit button

<input name="txtSearch" type="text" id="txtSearch" class="field" />            
<input type="submit" name="btnSearch" value="" id="btnSearch" class="btn" onclick="javascript:SubmitFrm()" />

Works like a charm.

Use StringTokenizer to parse the string.

String s ="SALES:0,SALE_PRODUCTS:1,EXPENSES:2,EXPENSES_ITEMS:3";
    Map<String, Integer> lMap=new HashMap<String, Integer>();


    StringTokenizer st=new StringTokenizer(s, ",");
    while(st.hasMoreTokens())
    {
        String [] array=st.nextToken().split(":");
        lMap.put(array[0], Integer.valueOf(array[1]));
    }

Are you sure you're running your unit tests in Debug? Debug.WriteLine won't be called in Release builds.

Two options to try are:

• Trace.WriteLine(), which is built into release builds as well as debug

• Undefine DEBUG in your build settings for the unit test

Without actually using the object, it looks like using either getNames() or keys() which returns an Iterator is the way to go.

Add return false; to the handler to prevent that.

Building on other answers, a simple solution based on a specific serializer that just converts datetime.datetime and datetime.date objects to strings.

from datetime import date, datetime

def json_serial(obj):
    """JSON serializer for objects not serializable by default json code"""

    if isinstance(obj, (datetime, date)):
        return obj.isoformat()
    raise TypeError ("Type %s not serializable" % type(obj))

As seen, the code just checks to find out if object is of class datetime.datetime or datetime.date, and then uses .isoformat() to produce a serialized version of it, according to ISO 8601 format, YYYY-MM-DDTHH:MM:SS (which is easily decoded by JavaScript). If more complex serialized representations are sought, other code could be used instead of str() (see other answers to this question for examples). The code ends by raising an exception, to deal with the case it is called with a non-serializable type.

This json_serial function can be used as follows:

from datetime import datetime
from json import dumps

print dumps(datetime.now(), default=json_serial)

The details about how the default parameter to json.dumps works can be found in Section Basic Usage of the json module documentation.

While saving the response of get request, same error was thrown on Python 3.7 on window 10. The response received from the URL, encoding was UTF-8 so it is always recommended to check the encoding so same can be passed to avoid such trivial issue as it really kills lots of time in production

import requests
resp = requests.get('https://en.wikipedia.org/wiki/NIFTY_50')
print(resp.encoding)
with open ('NiftyList.txt', 'w') as f:
    f.write(resp.text)

When I added encoding="utf-8" with the open command it saved the file with the correct response

with open ('NiftyList.txt', 'w', encoding="utf-8") as f:
    f.write(resp.text)

The following code will work:

private WebView mWebView;
final Activity activity = this;

// private Button b;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mWebView = (WebView) findViewById(R.id.webview);
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.getSettings().setDomStorageEnabled(true);
    mWebView.setWebChromeClient(new WebChromeClient() {
        public void onProgressChanged(WebView view, int progress) {
            activity.setProgress(progress * 1000);
        }
    });

    mWebView.loadUrl("file:///android_asset/raw/NewFile1.html");
}

1. Configure AngularJS

$location / switching between html5 and hashbang mode / link rewriting

2. Configure your server:

https://github.com/angular-ui/ui-router/wiki/Frequently-Asked-Questions#wiki-how-to-configure-your-server-to-work-with-html5mode

i'd use a simple one line comparisant for these use cases

$username = trim($_POST['userName'])?:'Anonymous';

This is for the use case you are certain error logging is off so you don't get a warning that the variable isn't initialised.

this is the paranoid version:

$username = !empty(trim(isset($_POST['userName'])?$_POST['userName']:''))?$_POST['userName']:'Anonymous';

This implements a check if the $_POST variable is set. before accessing it.

Let's break down the full URL that a client would type into their address bar to reach your servlet:

http://www.example.com:80/awesome-application/path/to/servlet/path/info?a=1&b=2#boo

The parts are:

1. scheme: http
2. hostname: www.example.com
3. port: 80
4. context path: awesome-application
5. servlet path: path/to/servlet
6. path info: path/info
7. query: a=1&b=2
8. fragment: boo

The request URI (returned by getRequestURI) corresponds to parts 4, 5 and 6.

(incidentally, even though you're not asking for this, the method getRequestURL would give you parts 1, 2, 3, 4, 5 and 6).

Now:

• part 4 (the context path) is used to select your particular application out of many other applications that may be running in the server
• part 5 (the servlet path) is used to select a particular servlet out of many other servlets that may be bundled in your application's WAR
• part 6 (the path info) is interpreted by your servlet's logic (e.g. it may point to some resource controlled by your servlet).
• part 7 (the query) is also made available to your servlet using getQueryString
• part 8 (the fragment) is not even sent to the server and is relevant and known only to the client

The following always holds (except for URL encoding differences):

requestURI = contextPath + servletPath + pathInfo

The following example from the Servlet 3.0 specification is very helpful:

Note: image follows, I don't have the time to recreate in HTML:

I have tried www.wheresmymac.com they are cheap and they have great bandwith so their is low latency. You need teamviewer to log into the virtual system though

It is now the first example in the Jersey Client documentation

Example 5.1. POST request with form parameters

Client client = ClientBuilder.newClient();
WebTarget target = client.target("http://localhost:9998").path("resource");

Form form = new Form();
form.param("x", "foo");
form.param("y", "bar");

MyJAXBBean bean =
target.request(MediaType.APPLICATION_JSON_TYPE)
    .post(Entity.entity(form,MediaType.APPLICATION_FORM_URLENCODED_TYPE),
        MyJAXBBean.class);

Inner join - An inner join using either of the equivalent queries gives the intersection of the two tables, i.e. the two rows they have in common.
Left outer join - A left outer join will give all rows in A, plus any common rows in B.
Full outer join - A full outer join will give you the union of A and B, i.e. All the rows in A and all the rows in B. If something in A doesn't have a corresponding datum in B, then the B portion is null, and vice versa. check this

I used git prune origin and that did the work.

There's a set of useful extensions to IDLE called IDLEX that works with MacOS and Windows http://idlex.sourceforge.net/

It includes line numbering and I find it quite handy & free.

Otherwise there are a bunch of other IDEs some of which are free: https://wiki.python.org/moin/IntegratedDevelopmentEnvironments

You can use

String hex = String.format("#%02x%02x%02x", r, g, b);  

Use capital X's if you want your resulting hex-digits to be capitalized (#FFFFFF vs. #ffffff).

Everyone here is talking about the similarities of the two. I am gonna point out the differences.

1. Using new Object() allows you to pass another object. The obvious outcome is that the newly created object will be set to the same reference. Here is a sample code:

   var obj1 = new Object();
   obj1.a = 1;
   var obj2 = new Object(obj1);
   obj2.a // 1
   

2. The usage is not limited to objects as in OOP objects. Other types could be passed to it too. The function will set the type accordingly. For example if we pass integer 1 to it, an object of type number will be created for us.

   var obj = new Object(1);
   typeof obj // "number"
   

3. The object created using the above method (new Object(1)) would be converted to object type if a property is added to it.

   var obj = new Object(1);
   typeof obj // "number"
   obj.a = 2;
   typeof obj // "object"
   

4. If the object is a copy of a child class of object, we could add the property without the type conversion.

   var obj = new Object("foo");
   typeof obj // "object"
   obj === "foo" // true
   obj.a = 1;
   obj === "foo" // true
   obj.a // 1
   var str = "foo";
   str.a = 1;
   str.a // undefined
   

No, you can't make the img stretch to fit the div and simultaneously achieve the inverse. You would have an infinite resizing loop. However, you could take some notes from other answers and implement some min and max dimensions but that wasn't the question.

You need to decide if your image will scale to fit its parent or if you want the div to expand to fit its child img.

Using this block tells me you want the image size to be variable so the parent div is the width an image scales to. height: auto is going to keep your image aspect ratio in tact. if you want to stretch the height it needs to be 100% like this fiddle.

img {
    width: 100%;
    height: auto;
}

The approved solution doesn't work in my case, so my solution is the following one:

    ''' The column name in the example case is "Unnamed: 7"
 but it works with any other name ("Unnamed: 0" for example). '''

        df.rename({"Unnamed: 7":"a"}, axis="columns", inplace=True)

        # Then, drop the column as usual.

        df.drop(["a"], axis=1, inplace=True)

Hope it helps others.
