For JetBrains Rider:

First Option

1. Unload Project
2. Double click the unloaded project

Second option:

1. Click on the project
2. Press F4

That's it!

You can do it a number of ways, depending on the type of quotes you use:

• echo "<a href='http://www.whatever.com/$param'>Click here</a>";
• echo "<a href='http://www.whatever.com/{$param}'>Click here</a>";
• echo '<a href="http://www.whatever.com/' . $param . '">Click here</a>';
• echo "<a href=\"http://www.whatever.com/$param\">Click here</a>";

Double quotes allow for variables in the middle of the string, where as single quotes are string literals and, as such, interpret everything as a string of characters -- nothing more -- not even \n will be expanded to mean the new line character, it will just be the characters \ and n in sequence.

You need to be careful about your use of whichever type of quoting you decide. You can't use double quotes inside a double quoted string (as in your example) as you'll be ending the string early, which isn't what you want. You can escape the inner double quotes, however, by adding a backslash.

On a separate note, you might need to be careful about XSS attacks when printing unsafe variables (populated by the user) out to the browser.

Start each row with \"-\" to create bullet list.

This is almost your original proposal but almost a 1-liner. Not that complicated as other valid answers, and not so depending on bash versions (can work with old bashes).

OK=0 ; MP_FLAVOURS="vanilla lemon hazelnut straciatella"
for FLAV in $MP_FLAVOURS ; do [ $FLAV == $FLAVOR ] && { OK=1 ; break; } ; done
[ $OK -eq 0 ] && { echo "$FLAVOR not a valid value ($MP_FLAVOURS)" ; exit 1 ; }

I guess my proposal can still be improved, both in length and style.

No one mentioned .env in here yet? Make a .env file in your app root, then require('dotenv').config() and read the values. Easily changed, easily read, cross platform.

https://www.npmjs.com/package/dotenv

There are two ways that you can achieve this. Concatenation, and shift/rotate functions.

• Concatenation is the "manual" way of doing things. You specify what part of the original signal that you want to "keep" and then concatenate on data to one end or the other. For example: tmp <= tmp(14 downto 0) & '0';

• Shift functions (logical, arithmetic): These are generic functions that allow you to shift or rotate a vector in many ways. The functions are: sll (shift left logical), srl (shift right logical). A logical shift inserts zeros. Arithmetric shifts (sra/sla) insert the left most or right most bit, but work in the same way as logical shift. Note that for all of these operations you specify what you want to shift (tmp), and how many times you want to perform the shift (n bits)

• Rotate functions: rol (rotate left), ror (rotate right). Rotating does just that, the MSB ends up in the LSB and everything shifts left (rol) or the other way around for ror.

Here is a handy reference I found (see the first page).

1. Click on Window > Show view > Server OR right click on the server in "Servers" view, select "Properties".
2. OR Open the Overview screen for the server by double clicking it.
3. In the Server locations tab , select "Use Tomcat location".
4. Save the configurations and restart the Server.

This way Eclipse will take full control over Tomcat, this way you'll also be able to access the default Tomcat homepage with the Tomcat Manager when running from inside Eclipse.

There are two ways to read and write a file using JavaScript

1. Using JavaScript extensions

2. Using a web page and Active X objects

Recently used xlsx package, works well.

library(xlsx)
write.xlsx(x, file, sheetName="Sheet1")

where x is a data.frame

Firstly, the below method doesn't compile as it is missing the return type and it should be Long.MAX_VALUE in place of Long.Max_value.

public static boolean isBiggerThanMaxLong(long value) {
      return value > Long.Max_value;
}

The above method can never return true as you are comparing a long value with Long.MAX_VALUE , see the method signature you can pass only long there.Any long can be as big as the Long.MAX_VALUE, it can't be bigger than that.

You can try something like this with BigInteger class :

public static boolean isBiggerThanMaxLong(BigInteger l){
    return l.compareTo(BigInteger.valueOf(Long.MAX_VALUE))==1?true:false;
}

The below code will return true :

BigInteger big3 = BigInteger.valueOf(Long.MAX_VALUE).
                  add(BigInteger.valueOf(Long.MAX_VALUE));
System.out.println(isBiggerThanMaxLong(big3)); // prints true

This is the code:

f = open(filename, 'w')
f.write("hello\talex")

The \t inside the string is the escape sequence for the horizontal tabulation.

I was having the same issue in asp.NET razor C#

I had a ComboBox filled with titles from an EventMessage, and I wanted to show the Content of this message with its selected value to show it in a label or TextField or any other Control...

My ComboBox was filled like this:

 @Html.DropDownList("EventBerichten", new SelectList(ViewBag.EventBerichten, "EventBerichtenID", "Titel"), new { @class = "form-control", onchange = "$(this.form).submit();" })

In my EventController I had a function to go to the page, in which I wanted to show my ComboBox (which is of a different model type, so I had to use a partial view)?

The function to get from index to page in which to load the partial view:

  public ActionResult EventDetail(int id)
        {

            Event eventOrg = db.Event.Include(s => s.Files).SingleOrDefault(s => s.EventID == id);
            //  EventOrg eventOrg = db.EventOrgs.Find(id);
            if (eventOrg == null)
            {

                return HttpNotFound();
            }
            ViewBag.EventBerichten = GetEventBerichtenLijst(id);
            ViewBag.eventOrg = eventOrg;
            return View(eventOrg);
        }

The function for the partial view is here:

 public PartialViewResult InhoudByIdPartial(int id)
        {
            return PartialView(
                db.EventBericht.Where(r => r.EventID == id).ToList());

        }

The function to fill EventBerichten:

        public List<EventBerichten> GetEventBerichtenLijst(int id)
        {
            var eventLijst = db.EventBericht.ToList();
            var berLijst = new List<EventBerichten>();
            foreach (var ber in eventLijst)
            {
                if (ber.EventID == id )
                {
                    berLijst.Add(ber);
                }
            }
            return berLijst;
        }

The partialView Model looks like this:

@model  IEnumerable<STUVF_back_end.Models.EventBerichten>

<table>
    <tr>
        <th>
            EventID
        </th>
        <th>
            Titel
        </th>
        <th>
            Inhoud
        </th>
        <th>
            BerichtDatum
        </th>
        <th>
            BerichtTijd
        </th>

    </tr>

    @foreach (var item in Model)
    {
        <tr>
            <td>
                @Html.DisplayFor(modelItem => item.EventID)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.Titel)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.Inhoud)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.BerichtDatum)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.BerichtTijd)
            </td>

        </tr>
    }
</table>

VIEUW: This is the script used to get my output in the view

<script type="text/javascript">
    $(document).ready(function () {
        $("#EventBerichten").change(function () {
            $("#log").ajaxError(function (event, jqxhr, settings, exception) {
                alert(exception);
            });

            var BerichtSelected = $("select option:selected").first().text();
            $.get('@Url.Action("InhoudByIdPartial")',
                { EventBerichtID: BerichtSelected }, function (data) {
                    $("#target").html(data);
                });
        });
    });
            </script>
@{
                    Html.RenderAction("InhoudByIdPartial", Model.EventID);
                } 

<fieldset>
                <legend>Berichten over dit Evenement</legend>
                <div>
                    @Html.DropDownList("EventBerichten", new SelectList(ViewBag.EventBerichten, "EventBerichtenID", "Titel"), new { @class = "form-control", onchange = "$(this.form).submit();" })
                </div>

                <br />
                <div id="target">

                </div>
                <div id="log">

In Python 3, / is float division

In Python 2, / is integer division (assuming int inputs)

In both 2 and 3, // is integer division

(To get float division in Python 2 requires either of the operands be a float, either as 20. or float(20))

You can use a 'here' document with no command to send it to.

#!/bin/bash
echo "Say Something"
<<COMMENT1
    your comment 1
    comment 2
    blah

echo "Do something else"

You don't really need a sub-select:

SELECT a, COUNT(*) AS b,
   SUM( CASE WHEN c = 'const' THEN 1 ELSE 0 END ) as d,
   from t group by a order by b desc

To tell from the style of your code snippet, I suppose you were using IPython rather than Jupyter Notebook.

In this issue on GitHub, it was made clear by a member of IPython in 2016 that the display of charts would only work when "only work when it's a Jupyter kernel". Thus, the %matplotlib inline would not work.

I was just having the same issue and suggest you use Jupyter Notebook for the visualization.

WITH
  Digits AS (SELECT 0 D UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9),
  Dates AS (SELECT adddate('1970-01-01',t4.d*10000 + t3.d*1000 + t2.d*100 + t1.d*10 +t0.d) AS date FROM Digits AS t0, Digits AS t1, Digits AS t2, Digits AS t3, Digits AS t4)
SELECT * FROM Dates WHERE date BETWEEN '2017-01-01' AND '2017-12-31'

This should work for multiplication:

.data

.text
.globl  main

main:

# $4 * $5 = $2

    addi $4, $0, 0x9
    addi $5, $0, 0x6

    add  $2, $0, $0 # initialize product to zero

Loop:   
    beq  $5, $0, Exit # if multiplier is 0,terminate loop
    andi $3, $5, 1 # mask out the 0th bit in multiplier
    beq  $3, $0, Shift # if the bit is 0, skip add
    addu $2, $2, $4 # add (shifted) multiplicand to product

Shift: 
    sll $4, $4, 1 # shift up the multiplicand 1 bit
    srl $5, $5, 1 # shift down the multiplier 1 bit
    j Loop # go for next  

Exit: #


EXIT:

Here is the example directly from PEP 8 on limiting line length:

class Rectangle(Blob):

    def __init__(self, width, height,
                 color='black', emphasis=None, highlight=0):
        if (width == 0 and height == 0 and
                color == 'red' and emphasis == 'strong' or
                highlight > 100):
            raise ValueError("sorry, you lose")
        if width == 0 and height == 0 and (color == 'red' or
                                           emphasis is None):
            raise ValueError("I don't think so -- values are %s, %s" %
                             (width, height))
        Blob.__init__(self, width, height,
                      color, emphasis, highlight)

You can get the current date in a locale-agnostic way using

for /f "skip=1" %%x in ('wmic os get localdatetime') do if not defined MyDate set MyDate=%%x

Then you can extract the individual parts using substrings:

set today=%MyDate:~0,4%-%MyDate:~4,2%-%MyDate:~6,2%

Another way, where you get variables that contain the individual parts, would be:

for /f %%x in ('wmic path win32_localtime get /format:list ^| findstr "="') do set %%x
set today=%Year%-%Month%-%Day%

Much nicer than fiddling with substrings, at the expense of polluting your variable namespace.

If you need UTC instead of local time, the command is more or less the same:

for /f %%x in ('wmic path win32_utctime get /format:list ^| findstr "="') do set %%x
set today=%Year%-%Month%-%Day%

Try this one:

$this->db->select("*");
$this->db->where_in("(SELECT trans_id FROM myTable WHERE code = 'B')");
$this->db->where('code !=', 'B');
$this->db->get('myTable');

Note: $this->db->select("*"); is optional when you are selecting all columns from table

This code make clean dataframe:

df = pd.DataFrame({'a':[1,2], 'b':[3,4]})
#clean
df = pd.DataFrame()

You have to use val() instead of value() and you have missed starting quote id=dbType" should be id="dbType"

Live Demo

Change

selection = $('this').value();

To

selection = $(this).val();

or

selection = this.value;

You can use std::getline :

#include <fstream>
#include <string>

int main() 
{ 
    std::ifstream file("Read.txt");
    std::string str; 
    while (std::getline(file, str))
    {
        // Process str
    }
}

Also note that it's better you just construct the file stream with the file names in it's constructor rather than explicitly opening (same goes for closing, just let the destructor do the work).

Further documentation about std::string::getline() can be read at CPP Reference.

Probably the easiest way to read a whole text file is just to concatenate those retrieved lines.

std::ifstream file("Read.txt");
std::string str;
std::string file_contents;
while (std::getline(file, str))
{
  file_contents += str;
  file_contents.push_back('\n');
}

I prefer outputting my data into XML (using Castor, XStream or JAXB), then transforming it using a XSLT stylesheet into XSL-FO and render that with Apache FOP into PDF. Worked so far for 10-page reports and 400-page manuals. I found this more flexible and stylable than generating PDFs in code using iText.

Updated code from Brad with few things: You don't need Math.truncate, conversion to int or long automatically truncates the value. In my version I am using long instead of int (We will run out of 32 bit signed integers in 2038 year). Also, added timestamp parsing.

public static class DateTimeHelper
{
    /// <summary>
     /// Converts a given DateTime into a Unix timestamp
     /// </summary>

You can use below query to update or create comment on already created table.

SYNTAX:

COMMENT ON COLUMN TableName.ColumnName IS 'comment text';

Example:

COMMENT ON COLUMN TAB_SAMBANGI.MY_COLUMN IS 'This is a comment on my column...';

At least as of Apache commons-io 2.5, the IOUtils.toString() method supports an URI argument and returns contents of files located inside jars on the classpath:

IOUtils.toString(SomeClass.class.getResource(...).toURI(), ...)

Adding a bit to use Gokhan's solution for using:

--allow-file-access-from-files

Now you just need to append above text in Target text followed by a space. make sure you close all the instances of chrome browser after adding above property. Now restart chrome by the icon where you added this property. It should work for all.

You can also use it with Page Object Pattern, e.g:

Try this code:

@FindBy(xpath = "//*[contains(text(), 'Best Choice')]")
WebElement buttonBestChoice;

This should work same :

SELECT MAX(salary) max_salary,
  (SELECT MAX(salary)
   FROM Employee
   WHERE salary NOT IN
       (SELECT MAX(salary)
        FROM Employee)) 2nd_max_salary
FROM Employee

I got here looking for a way to add a key/value pair(s) as a group - in my case it was the output of a function call, so adding the pair using dictionary[key] = value would require me to know the name of the key(s).

In this case, you can use the update method: dictionary.update(function_that_returns_a_dict(*args, **kwargs)))

Beware, if dictionary already contains one of the keys, the original value will be overwritten.

Well, It's a bit late for this but I've just started learning Qt and maybe this could help somebody out there:

If you're using Qt Creator then when you've started creating the project you were asked to choose a kit to be used with your project, Let's say you chose Desktop Qt <version-here> MinGW 64-bit. For Qt 5, If you opened the Qt folder of your installation, you'll find a folder with the version of Qt installed as its name inside it, here you can find the kits you can choose from.

You can go to /PATH/FOR/Qt/mingw<version>_64/include and here you'll find all the includes you can use in your program, just search for QApplication and you'll find it inside the folder QtWidgets, So you can use #include <QtWidgets/QApplication> since the path starts from the include folder.

The same goes for other headers if you're stuck with any and for other kits.

Note: "all the includes you can use" doesn't mean these are the only ones you can use, If you include iostream for example then the compiler will include it from /PATH/FOR/Qt/Tools/mingw<version>_64/lib/gcc/x86_64-w64-mingw32/7.3.0/include/c++/iostream

Another way to do it in async function :

const express = require('express')
const path = require('path')
const db = require(path.join(__dirname, '../database/config')).db;
const router = express.Router()

// Create.R.U.D
router.post('/new-order', async function (req, res, next) {

    // security check
    if (Object.keys(req.body).length === 0) {
        res.status(404).send({
            msg: "Error",
            code: 404
        });
        return;
    }

    try {

        // operations
        let orderNumber = await db.collection('orders').countDocuments()
        let number = orderNumber + 1
        let order = {
            number: number,
            customer: req.body.customer,
            products: req.body.products,
            totalProducts: req.body.totalProducts,
            totalCost: req.body.totalCost,
            type: req.body.type,
            time: req.body.time,
            date: req.body.date,
            timeStamp: Date.now(),

        }

        if (req.body.direction) {
            order.direction = req.body.direction
        }

        if (req.body.specialRequests) {
            order.specialRequests = req.body.specialRequests
        }

        // Here newOrder will store some informations in result of this process.
        // You can find the inserted id and some informations there too.
        
        let newOrder = await db.collection('orders').insertOne({...order})

        if (newOrder) {

            // MARK: Server response
            res.status(201).send({
                msg: `Order N°${number} created : id[${newOrder.insertedId}]`,
                code: 201
            });

        } else {

            // MARK: Server response
            res.status(404).send({
                msg: `Order N°${number} not created`,
                code: 404
            });

        }

    } catch (e) {
        print(e)
        return
    }

})

// C.Read.U.D

module.exports = router;

If the program won't work without the files it seems like splitting them into a separate repo is a bad idea. We have large test suites that we break into a separate repo but those are truly "auxiliary" files.

However, you may be able to manage the files in a separate repo and then use git-submodule to pull them into your project in a sane way. So, you'd still have the full history of all your source but, as I understand it, you'd only have the one relevant revision of your images submodule. The git-submodule facility should help you keep the correct version of the code in line with the correct version of the images.

Here's a good introduction to submodules from Git Book.

I love doing du -sh * | sort -nr | less to sort by the largest files first

To set custom error message for HTML 5 validation use,

oninvalid="this.setCustomValidity('Your custom message goes here.')"

and to remove this message when user enters valid data use,

onkeyup="setCustomValidity('')"

Hope this works for you. Enjoy ;)

There is a simple and very common technique by using 2 background images: a crisp and a blurry one. You set the crisp image as a background for the body and the blurry one as a background image for your container. The blurry image must be set to fixed positioning and the alignment is 100% perfect. I used it before and it works.

body {
    background: url(yourCrispImage.jpg) no-repeat;
}

#container {
    background: url(yourBlurryImage.jpg) no-repeat fixed;
}

You can see a working example at the following fiddle: http://jsfiddle.net/jTUjT/5/. Try to resize the browser and see that the alignment never fails.

If only CSS element() was supported by other browsers other than Mozilla's -moz-element() you could create great effects. See this demo with Mozilla.

Late answer - I found the other answers useful - and wanted to add a bit extra.

How do I dump preprocessor macros coming from a particular header file?

echo "#include <sys/socket.h>" | gcc -E -dM -

or (thanks to @mymedia for the suggestion):

gcc -E -dM -include sys/socket.h - < /dev/null

In particular, I wanted to see what SOMAXCONN was defined to on my system. I know I could just open up the standard header file, but sometimes I have to search around a bit to find the header file locations. Instead I can just use this one-liner:

$ gcc -E -dM -include sys/socket.h - < /dev/null | grep SOMAXCONN
#define SOMAXCONN 128
$ 

You aren't being very clear about what you want here, since I think @DWin's is technically correct, given your example code. I think what you really want is this:

y1 <- c(100, 200, 300, 400, 500)
y2 <- c(1, 2, 3, 4, 5)
x <- c(1, 2, 3, 4, 5)

# first plot
plot(x, y1,ylim = range(c(y1,y2)))

# Add points
points(x, y2)

DWin's solution was operating under the implicit assumption (based on your example code) that you wanted to plot the second set of points overlayed on the original scale. That's why his image looks like the points are plotted at 1, 101, etc. Calling plot a second time isn't what you want, you want to add to the plot using points. So the above code on my machine produces this:

But DWin's main point about using ylim is correct.

I had the same problem with a spring boot project. The solution was to downgrade the spring-boot-starter-parent dependency version from 2.0.0.RELEASE to 1.5.10.RELEASE(you can move to any stable version)

from:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

to

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.10.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

<foo name="port">
   <value>${my.server.port:8088}</value>
</foo>

should work for you to have 8088 as default port

See also: http://blog.callistaenterprise.se/2011/11/17/configure-your-spring-web-application/

There are some webkit css properties that should work on Chrome/Safari at least:

-webkit-text-stroke-width: 2px;
-webkit-text-stroke-color: black;

That's a 2px wide black text outline.

Update for Django 1.10+:

is_authenticated is now an attribute in Django 1.10.

The method was removed in Django 2.0.

For Django 1.9 and older:

is_authenticated is a function. You should call it like

if request.user.is_authenticated():
    # do something if the user is authenticated

As Peter Rowell pointed out, what may be tripping you up is that in the default Django template language, you don't tack on parenthesis to call functions. So you may have seen something like this in template code:

{% if user.is_authenticated %}

However, in Python code, it is indeed a method in the User class.

This will also work

SELECT NAME 
FROM GEO_LOCATION
WHERE MODIFY_ON BETWEEN SYSDATE() - INTERVAL 2 HOUR AND SYSDATE()

In Chrome, request with 'Content-Type:application/json' shows as Request PayedLoad and sends data as json object.

But request with 'Content-Type:application/x-www-form-urlencoded' shows Form Data and sends data as Key:Value Pair, so if you have array of object in one key it flats that key's value:

{ Id: 1, 
name:'john', 
phones:[{title:'home',number:111111,...},
        {title:'office',number:22222,...}]
}

sends

{ Id: 1, 
name:'john', 
phones:[object object]
phones:[object object]
}

Your error is in resultCode = Activity.RESULT_CANCELED, you should instance like resultCode == Activity.RESULT_CANCELED ==

A DBMS is used for storage of data in files. In DBMS relationships can be established between two files. Data is stored in flat files with metadata whereas RDBMS stores the data in tabular form with additional condition of data that enforces relationships among the tables. Unlike RDBMS, DBMS does not support client server architecture. RDBMS imposes integrity constraints and also follows normalization which is not supported in DBMS.

I would not say it is a standard way to swap because it will cause some unexpected errors.

nums[i], nums[nums[i] - 1] = nums[nums[i] - 1], nums[i]

nums[i] will be modified first and then affect the second variable nums[nums[i] - 1].

I find using vintage mode works really well with sublime multiselect.

My most used keys would be "w" for jumping a word, "^" and "$" to move to first/last character of the line. Combinations like "2dw" (delete the next two words after the cursor) make using multiselect really powerful.

This sounds obvious but has really sped up my workflow, especially when editing HTML.

I had to create a timer for teachers grading students' work. Here's one I used which is entirely based on elapsed time since the grading begun by storing the system time at the point that the page is loaded, and then comparing it every half second to the system time at that point:

var startTime = Math.floor(Date.now() / 1000); //Get the starting time (right now) in seconds
localStorage.setItem("startTime", startTime); // Store it if I want to restart the timer on the next page

function startTimeCounter() {
    var now = Math.floor(Date.now() / 1000); // get the time now
    var diff = now - startTime; // diff in seconds between now and start
    var m = Math.floor(diff / 60); // get minutes value (quotient of diff)
    var s = Math.floor(diff % 60); // get seconds value (remainder of diff)
    m = checkTime(m); // add a leading zero if it's single digit
    s = checkTime(s); // add a leading zero if it's single digit
    document.getElementById("idName").innerHTML = m + ":" + s; // update the element where the timer will appear
    var t = setTimeout(startTimeCounter, 500); // set a timeout to update the timer
}

function checkTime(i) {
    if (i < 10) {i = "0" + i};  // add zero in front of numbers < 10
    return i;
}

startTimeCounter();

This way, it really doesn't matter if the 'setTimeout' is subject to execution delays, the elapsed time is always relative the system time when it first began, and the system time at the time of update.

<?php

    require 'database.php';

    $id = $_GET['id'];

    $image = "SELECT * FROM slider WHERE id = '$id'";
    $query = mysqli_query($connect, $image);
    $after = mysqli_fetch_assoc($query);

    if ($after['image'] != 'default.png') {
        unlink('../slider/'.$after['image']);
    }

    $delete = "DELETE FROM slider WHERE id = $id";
    $query = mysqli_query($connect, $delete);

    if ($query) {
        header('location: slider.php');
    }

?>

Slash is a date delimiter, so that will use the current culture date delimiter.

If you want to hard-code it to always use slash, you can do something like this:

DateTime.ToString("dd'/'MM'/'yyyy")

As detailed in the jTDS Frequenlty Asked Questions, the URL format for jTDS is:

jdbc:jtds:<server_type>://<server>[:<port>][/<database>][;<property>=<value>[;...]]

So, to connect to a database called "Blog" hosted by a MS SQL Server running on MYPC, you may end up with something like this:

jdbc:jtds:sqlserver://MYPC:1433/Blog;instance=SQLEXPRESS;user=sa;password=s3cr3t

Or, if you prefer to use getConnection(url, "sa", "s3cr3t"):

jdbc:jtds:sqlserver://MYPC:1433/Blog;instance=SQLEXPRESS

EDIT: Regarding your Connection refused error, double check that you're running SQL Server on port 1433, that the service is running and that you don't have a firewall blocking incoming connections.

That's too complex to set in the definition. You can set the definition to null though, and then in the constructor, check it, and if it has not been changed - set it:

private static $dates = null;
public function __construct()
{
    if (is_null(self::$dates)) {  // OR if (!is_array(self::$date))
         self::$dates = array( /* .... */);
    }
}

This worked:

$("#theSelectId").prepend("<option value='' selected='selected'></option>");

Firebug Output:

<select id="theSelectId">
  <option selected="selected" value=""/>
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>

You could also use .prependTo if you wanted to reverse the order:

?$("<option>", { value: '', selected: true }).prependTo("#theSelectId");???????????

I've tried all the solutions from the answers but couldn't get mysql command to work from the terminal, always getting the message

bash: command not found

The solution is to change the .bash_profile, and add the mysql path to .bash_profile

To do so follow these steps: 1. Open a new Terminal window or make sure you are in the home directory 2. Open .bash_profile using

nano .bash_profile

3. Add the following command to add the mysql path

PATH="/usr/local/mysql/bin:${PATH}"
export PATH

4. Press Ctrl+X, then press y and press enter.

The following is how my .bash_profile looks like

It's actually very easy in jQuery:

$("#ddl_1").clone().attr("id",newId).appendTo("body");

Change .appendTo() of course...

You have to install Microsoft.Bcl.Async NuGet package to be able to use async/await constructs in pre-.NET 4.5 versions (such as Silverlight 4.0+)

Just for clarity - this package used to be called Microsoft.CompilerServices.AsyncTargetingPack and some old tutorials still refer to it.

Take a look here for info from Immo Landwerth.

Just do a \r with a find and replace with a blank in the replace field so everything goes up to one line. Then do a find and replace (in my case by semi colon) and replace with ;\n

No. "In scope" variables are determined by the "scope chain", which is not accessible programmatically.

For detail (quite a lot of it), check out the ECMAScript (JavaScript) specification. Here's a link to the official page where you can download the canonical spec (a PDF), and here's one to the official, linkable HTML version.

Update based on your comment to Camsoft

The variables in scope for your event function are determined by where you define your event function, not how they call it. But, you may find useful information about what's available to your function via this and arguments by doing something along the lines of what KennyTM pointed out (for (var propName in ____)) since that will tell you what's available on various objects provided to you (this and arguments; if you're not sure what arguments they give you, you can find out via the arguments variable that's implicitly defined for every function).

So in addition to whatever's in-scope because of where you define your function, you can find out what else is available by other means by doing:

var n, arg, name;
alert("typeof this = " + typeof this);
for (name in this) {
    alert("this[" + name + "]=" + this[name]);
}
for (n = 0; n < arguments.length; ++n) {
    arg = arguments[n];
    alert("typeof arguments[" + n + "] = " + typeof arg);
    for (name in arg) {
        alert("arguments[" + n + "][" + name + "]=" + arg[name]);
    }
}

(You can expand on that to get more useful information.)

Instead of that, though, I'd probably use a debugger like Chrome's dev tools (even if you don't normally use Chrome for development) or Firebug (even if you don't normally use Firefox for development), or Dragonfly on Opera, or "F12 Developer Tools" on IE. And read through whatever JavaScript files they provide you. And beat them over the head for proper docs. :-)

You can either use:

<button onclick="window.history.back()">Back</button>

or..

<button onclick="window.history.go(-1)">Back</button>

The difference, of course, is back() only goes back 1 page but go() goes back/forward the number of pages you pass as a parameter, relative to your current page.

Overall

Assuming everything descends from object (you are on your own if it doesn't), Python computes a method resolution order (MRO) based on your class inheritance tree. The MRO satisfies 3 properties:

• Children of a class come before their parents
• Left parents come before right parents
• A class only appears once in the MRO

If no such ordering exists, Python errors. The inner workings of this is a C3 Linerization of the classes ancestry. Read all about it here: https://www.python.org/download/releases/2.3/mro/

Thus, in both of the examples below, it is:

1. Child
2. Left
3. Right
4. Parent

When a method is called, the first occurrence of that method in the MRO is the one that is called. Any class that doesn't implement that method is skipped. Any call to super within that method will call the next occurrence of that method in the MRO. Consequently, it matters both what order you place classes in inheritance, and where you put the calls to super in the methods.

With super first in each method

class Parent(object):
    def __init__(self):
        super(Parent, self).__init__()
        print "parent"

class Left(Parent):
    def __init__(self):
        super(Left, self).__init__()
        print "left"

class Right(Parent):
    def __init__(self):
        super(Right, self).__init__()
        print "right"

class Child(Left, Right):
    def __init__(self):
        super(Child, self).__init__()
        print "child"

Child() Outputs:

parent
right
left
child

With super last in each method

class Parent(object):
    def __init__(self):
        print "parent"
        super(Parent, self).__init__()

class Left(Parent):
    def __init__(self):
        print "left"
        super(Left, self).__init__()

class Right(Parent):
    def __init__(self):
        print "right"
        super(Right, self).__init__()

class Child(Left, Right):
    def __init__(self):
        print "child"
        super(Child, self).__init__()

Child() Outputs:

child
left
right
parent

Steps to manually configure DNS:

1. You can access Network and Sharing center by right clicking on the Network icon on the taskbar.

2. Now choose adapter settings from the side menu.

3. This will give you a list of the available network adapters in the system . From them right click on the adapter you are using to connect to the internet now and choose properties option.

4. In the networking tab choose ‘Internet Protocol Version 4 (TCP/IPv4)’.

5. Now you can see the properties dialogue box showing the properties of IPV4. Here you need to change some properties.

   Select ‘use the following DNS address’ option. Now fill the following fields as given here.

   Preferred DNS server: 208.67.222.222

   Alternate DNS server : 208.67.220.220

   This is an available Open DNS address. You may also use google DNS server addresses.

   After filling these fields. Check the ‘validate settings upon exit’ option. Now click OK.

You have to add this DNS server address in the router configuration also (by referring the router manual for more information).

Refer : for above method & alternative

If none of this works, then open command prompt(Run as Administrator) and run these:

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
NETSH winsock reset catalog
NETSH int ipv4 reset reset.log
NETSH int ipv6 reset reset.log
Exit

Hopefully that fixes it, if its still not fixed there is a chance that its a NIC related issue(driver update or h/w).

Also FYI, this has a thread on Microsoft community : Windows 10 - DNS Issue

Simply use

var xmlString = '<?xml version="1.0" ?><root />';
var xml = jQuery.parseXML(xml);

It's jQuery.parseXML, so no need to worry about cross-browser tricks. Use jQuery as like HTML, it's using the native XML engine.

if you want to copy multiple folders to multiple folders one can do something like this:

echo dir1 dir2 dir3 | xargs -n 1 cp -r /path/toyourdir/{subdir1,subdir2,subdir3}

This worked for me:

string connection = System.Configuration.ConfigurationManager.ConnectionStrings["Test"].ConnectionString;

Outputs:

Data Source=.;Initial Catalog=OmidPayamak;IntegratedSecurity=True"

You can use OnClientClick event to call a JavaScript function:

<asp:Button ID="Button1" runat="server" Text="Button" onclientclick='redirect()' />

JavaScript code:

function redirect() {
  location.href = 'page.aspx';
}

But i think the best would be to style a hyperlink with css.

Example :

.button {
  display: block;

-moz-device-pixel-ratio
Gives the number of device pixels per CSS pixel.

this is almost self-explaining. the number describes the ratio of how much "real" pixels (physical pixerls of the screen) are used to display one "virtual" pixel (size set in CSS).

You can use getElementsByName("input") to get a collection of all the inputs on the page. Then loop through the collection, checking the name on the way. Something like this:

<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>JS Bin</title>

</head>
<body>

  <input name="q1_a" type="text" value="1A"/>
  <input name="q1_b" type="text" value="1B"/>
  <input name="q1_c" type="text" value="1C"/>
  <input name="q2_d" type="text" value="2D"/>

  <script type="text/javascript">
  var inputs = document.getElementsByTagName("input");
  for (x = 0 ; x < inputs.length ; x++){
    myname = inputs[x].getAttribute("name");
    if(myname.indexOf("q1_")==0){
      alert(myname);
      // do more stuff here
       }
    }
    </script>
</body>
</html>

This depends not only on the operating system in question, but also on configuration, potentially real-time configuration.

For Linux:

cat /proc/sys/fs/file-max

will show the current maximum number of file descriptors total allowed to be opened simultaneously. Check out http://www.cs.uwaterloo.ca/~brecht/servers/openfiles.html

Loop through the Items and Add to the Collection. You can use the Add method

List<string>items=new List<string>();
using (var con= new SqlConnection("yourConnectionStringHere")
{
    string qry="SELECT Column1 FROM Table1";
    var cmd= new SqlCommand(qry, con);
    cmd.CommandType = CommandType.Text;
    con.Open();
    using (SqlDataReader objReader = cmd.ExecuteReader())
    {
        if (objReader.HasRows)
        {              
            while (objReader.Read())
            {
              //I would also check for DB.Null here before reading the value.
               string item= objReader.GetString(objReader.GetOrdinal("Column1"));
               items.Add(item);                  
            }
        }
    }
}

As an extension to @JBNizet's answer for more technical users here's what implementation of org.w3c.dom.Node interface in com.sun.org.apache.xerces.internal.dom.ParentNode looks like, gives you the idea how it actually works.

public void normalize() {
    // No need to normalize if already normalized.
    if (isNormalized()) {
        return;
    }
    if (needsSyncChildren()) {
        synchronizeChildren();
    }
    ChildNode kid;
    for (kid = firstChild; kid != null; kid = kid.nextSibling) {
         kid.normalize();
    }
    isNormalized(true);
}

It traverses all the nodes recursively and calls kid.normalize()
This mechanism is overridden in org.apache.xerces.dom.ElementImpl

public void normalize() {
     // No need to normalize if already normalized.
     if (isNormalized()) {
         return;
     }
     if (needsSyncChildren()) {
         synchronizeChildren();
     }
     ChildNode kid, next;
     for (kid = firstChild; kid != null; kid = next) {
         next = kid.nextSibling;

         // If kid is a text node, we need to check for one of two
         // conditions:
         //   1) There is an adjacent text node
         //   2) There is no adjacent text node, but kid is
         //      an empty text node.
         if ( kid.getNodeType() == Node.TEXT_NODE )
         {
             // If an adjacent text node, merge it with kid
             if ( next!=null && next.getNodeType() == Node.TEXT_NODE )
             {
                 ((Text)kid).appendData(next.getNodeValue());
                 removeChild( next );
                 next = kid; // Don't advance; there might be another.
             }
             else
             {
                 // If kid is empty, remove it
                 if ( kid.getNodeValue() == null || kid.getNodeValue().length() == 0 ) {
                     removeChild( kid );
                 }
             }
         }

         // Otherwise it might be an Element, which is handled recursively
         else if (kid.getNodeType() == Node.ELEMENT_NODE) {
             kid.normalize();
         }
     }

     // We must also normalize all of the attributes
     if ( attributes!=null )
     {
         for( int i=0; i<attributes.getLength(); ++i )
         {
             Node attr = attributes.item(i);
             attr.normalize();
         }
     }

    // changed() will have occurred when the removeChild() was done,
    // so does not have to be reissued.

     isNormalized(true);
 } 

Hope this saves you some time.

firstOrCreate() checks for all the arguments to be present before it finds a match. If not all arguments match, then a new instance of the model will be created.

If you only want to check on a specific field, then use firstOrCreate(['field_name' => 'value']) with only one item in the array. This will return the first item that matches, or create a new one if not matches are found.

The difference between firstOrCreate() and firstOrNew():

• firstOrCreate() will automatically create a new entry in the database if there is not match found. Otherwise it will give you the matched item.
• firstOrNew() will give you a new model instance to work with if not match was found, but will only be saved to the database when you explicitly do so (calling save() on the model). Otherwise it will give you the matched item.

Choosing between one or the other depends on what you want to do. If you want to modify the model instance before it is saved for the first time (e.g. setting a name or some mandatory field), you should use firstOrNew(). If you can just use the arguments to immediately create a new model instance in the database without modifying it, you can use firstOrCreate().

If you are on Windows, here is a PowerShell script that will print the 10 largest files in your repository:

$revision_objects = git rev-list --objects --all;
$files = $revision_objects.Split() | Where-Object {$_.Length -gt 0 -and $(Test-Path -Path $_ -PathType Leaf) };
$files | Get-Item -Force | select fullname, length | sort -Descending -Property Length | select -First 10

setup.py is designed to be run from the command line. You'll need to open your command prompt (In Windows 7, hold down shift while right-clicking in the directory with the setup.py file. You should be able to select "Open Command Window Here").

From the command line, you can type

python setup.py --help

...to get a list of commands. What you are looking to do is...

python setup.py install

In perl, for an input of 1 (A), 27 (AA), etc.

sub excel_colname {
  my ($idx) = @_;       # one-based column number
  --$idx;               # zero-based column index
  my $name = "";
  while ($idx >= 0) {
    $name .= chr(ord("A") + ($idx % 26));
    $idx   = int($idx / 26) - 1;
  }
  return scalar reverse $name;
}

Note: This is the somewhat crude solution I posted myself, after not finding an answer here on Stack Overflow. It allows for only one array being passed, and it being the last element of the parameter list. Actually, it is not passing the array at all, but a list of its elements, which are re-assembled into an array by called_function(), but it worked for me. Somewhat later Ken posted his solution, but I kept mine here for "historic" reference.

calling_function()
{
    variable="a"
    array=( "x", "y", "z" )
    called_function "${variable}" "${array[@]}"
}

called_function()
{
    local_variable="${1}"
    shift
    local_array=("${@}")
}

Add next methods to your FragmentPagerAdapter:

public Fragment getActiveFragment(ViewPager container, int position) {
String name = makeFragmentName(container.getId(), position);
return  mFragmentManager.findFragmentByTag(name);
}

private static String makeFragmentName(int viewId, int index) {
    return "android:switcher:" + viewId + ":" + index;
}

getActiveFragment(0) has to work.

Here is the solution implemented into ViewPager https://gist.github.com/jacek-marchwicki/d6320ba9a910c514424d. If something fail you will see good crash log.

According to the error message, you declared myLoc as a pointer to an NSInteger (NSInteger *myLoc) rather than an actual NSInteger (NSInteger myLoc). It needs to be the latter.

I've had a similar issue with this error. In my case, I was entering the incorrect password for the Keystore.

I changed the password for the Keystore to match what I was entering (I didn't want to change the password I was entering), but it still gave the same error.

keytool -storepasswd -keystore keystore.jks

Problem was that I also needed to change the Key's password within the Keystore.

When I initially created the Keystore, the Key was created with the same password as the Keystore (I accepted this default option). So I had to also change the Key's password as follows:

keytool -keypasswd  -alias my.alias -keystore keystore.jks

Setattr: We use setattr to add an attribute to our class instance. We pass the class instance, the attribute name, and the value. and with getattr we retrive these values

For example

Employee = type("Employee", (object,), dict())

employee = Employee()

# Set salary to 1000
setattr(employee,"salary", 1000 )

# Get the Salary
value = getattr(employee, "salary")

print(value)

Floating point math is vulnerable to slight, but annoying, precision inaccuracies. If you can work with integer or fixed point, you will be guaranteed precision.

Note: This solution is using pylab, not matplotlib.pyplot

You may try using hist to put your data info along with the fitted curve as below:

import numpy as np
import scipy.stats as stats
import pylab as pl

h = sorted([186, 176, 158, 180, 186, 168, 168, 164, 178, 170, 189, 195, 172,
     187, 180, 186, 185, 168, 179, 178, 183, 179, 170, 175, 186, 159,
     161, 178, 175, 185, 175, 162, 173, 172, 177, 175, 172, 177, 180])  #sorted

fit = stats.norm.pdf(h, np.mean(h), np.std(h))  #this is a fitting indeed

pl.plot(h,fit,'-o')

pl.hist(h,normed=True)      #use this to draw histogram of your data

pl.show()                   #use may also need add this 

For examle

git stash show --name-only

At the end of the day it doesn't matter because C++ compilers can deal with the files in either format. If it's a real issue within your team, flip a coin and move on to the actual work.

Output is buffered.

stdout is line-buffered by default, which means that '\n' is supposed to flush the buffer. Why is it not happening in your case? I don't know. I need more info about your application/environment.

However, you can control buffering with setvbuf():

setvbuf(stdout, NULL, _IOLBF, 0);

This will force stdout to be line-buffered.

setvbuf(stdout, NULL, _IONBF, 0);

This will force stdout to be unbuffered, so you won't need to use fflush(). Note that it will severely affect application performance if you have lots of prints.

Let's say that you have class A that contain class B When you want to call some function of class B outside class A you will simply obtain a pointer to this class and you can do whatever you want and it will also change context of class B in your class A

But be careful with dynamic object

The command above worked for me

This is a late contribution, but there is a valid case for casting json_decode with (array).
Consider the following:

$jsondata = '';
$arr = json_decode($jsondata, true);
foreach ($arr as $k=>$v){
    echo $v; // etc.
}

If $jsondata is ever returned as an empty string (as in my experience it often is), json_decode will return NULL, resulting in the error Warning: Invalid argument supplied for foreach() on line 3. You could add a line of if/then code or a ternary operator, but IMO it's cleaner to simply change line 2 to ...

$arr = (array) json_decode($jsondata,true);

... unless you are json_decodeing millions of large arrays at once, in which case as @TCB13 points out, performance could be negatively effected.

canvas.toDataURL is not working if the original image URL (either relative or absolute) does not belong to the same domain as the web page. Tested from a bookmarklet and a simple javascript in the web page containing the images. Have a look to David Walsh working example. Put the html and images on your own web server, switch original image to relative or absolute URL, change to an external image URL. Only the first two cases are working.

This was a bug fixed in version 4.3.11 https://hibernate.atlassian.net/browse/HHH-2851

EDIT: Best way to execute a native query is still to use NamedParameterJdbcTemplate It allows you need to retrieve a result that is not a managed entity ; you can use a RowMapper and even a Map of named parameters!

private NamedParameterJdbcTemplate namedParameterJdbcTemplate;

@Autowired
public void setDataSource(DataSource dataSource) {
    this.namedParameterJdbcTemplate = new NamedParameterJdbcTemplate(dataSource);
}

final List<Long> resultList = namedParameterJdbcTemplate.query(query, 
            mapOfNamedParamters, 
            new RowMapper<Long>() {
        @Override
        public Long mapRow(ResultSet rs, int rowNum) throws SQLException {
            return rs.getLong(1);
        }
    });

I solved this problem by changing the maven setting.xml and repository

The only problem you would run into is if the norm of V is zero (or very close to it). This could give you Inf or NaN when you divide, along with a divide-by-zero warning. If you don't care about getting an Inf or NaN, you can just turn the warning on and off using WARNING:

oldState = warning('off','MATLAB:divideByZero');  % Return previous state then
                                                  %   turn off DBZ warning
uV = V/norm(V);
warning(oldState);  % Restore previous state

If you don't want any Inf or NaN values, you have to check the size of the norm first:

normV = norm(V);
if normV > 0,  % Or some other threshold, like EPS
  uV = V/normV;
else,
  uV = V;  % Do nothing since it's basically 0
end

If I need it in a program, I usually put the above code in my own function, usually called unit (since it basically turns a vector into a unit vector pointing in the same direction).

if you hit the "back" button it usually tends to stick, what you can do is when the form is submitted clear the element then before it goes to the next page but after doing with the element what you need to.

    $('#shares').keyup(function(){
                payment = 0;
                calcTotal();
                gtotal = ($('#shares').val() * 1) + payment;
                gtotal = gtotal.toFixed(2);
                $('#shares').val('');
                $("p.total").html("Total Payment: <strong>" + gtotal + "</strong>");
            });

1. In wp-config.php add define('FS_METHOD', 'direct');

I used tensorflow 1.8 to train my model and there is no problem for now. Tensorflow 2.0 alpha is not suitable with object detection API

Another alternative is;

sudo iptables -A INPUT -p tcp --dport 8000 -s ! 1.2.3.4 -j DROP

I had similar issue that 3 bridged virtualmachine just need access eachother with different combination, so I have tested this command and it works well.

Edit**

According to Fernando comment and this link exclamation mark (!) will be placed before than -s parameter:

sudo iptables -A INPUT -p tcp --dport 8000 ! -s 1.2.3.4 -j DROP

Try this

java -jar <jar-file-name>.jar

Debian appears to include the following:

• mpiCC.openmpi
• mpic++.openmpi
• mpicc.openmpi
• mpicxx.openmpi
• mpif77.openmpi
• mpif90.openmpi

I'll test symlinks of each for mpic, etc., and see if that helps the likes of HDF5-openmpi enabled find mpi.h.

Take that back Debian includes symlinks via their alternatives system and it still cannot find the proper paths between HDF5 openmpi packages and mpi.h referenced in the H5public.h header.

Here is a great way to build dynamic fields for a pivot query:

--summarize values to a tmp table

declare @STR varchar(1000)
SELECT  @STr =  COALESCE(@STr +', ', '') 
+ QUOTENAME(DateRange) 
from (select distinct DateRange, ID from ##pivot)d order by ID

---see the fields generated

print @STr

exec('  .... pivot code ...
pivot (avg(SalesAmt) for DateRange IN (' + @Str +')) AS P
order by Decile')

I got this error because I was serving from my file system. Once I started with a http server chrome could figure it out.

DateTime  dt  = new DateTime(laterDate);        

DateTime newDate = dt.minus( new  DateTime ( previousDate ).getMillis());

System.out.println("No of days : " + newDate.getDayOfYear() - 1 );    

[This is a late answer addressing the title of the question (since that is what people would encounter when searching) rather than the specifics of OP's question which has already been answered adequately]

Ubound is a bit fragile in that it provides no way to know how many dimensions an array has. You can use error trapping to determine the full layout of an array. The following returns a collection of arrays, one for each dimension. The count property can be used to determine the number of dimensions and their lower and upper bounds can be extracted as needed:

Function Bounds(A As Variant) As Collection
    Dim C As New Collection
    Dim v As Variant, i As Long

    On Error GoTo exit_function
    i = 1
    Do While True
        v = Array(LBound(A, i), UBound(A, i))
        C.Add v
        i = i + 1
    Loop
exit_function:
    Set Bounds = C
End Function

Used like this:

Sub test()
    Dim i As Long
    Dim A(1 To 10, 1 To 5, 4 To 10) As Integer
    Dim B(1 To 5) As Variant
    Dim C As Variant
    Dim sizes As Collection

    Set sizes = Bounds(A)
    Debug.Print "A has " & sizes.Count & " dimensions:"
    For i = 1 To sizes.Count
        Debug.Print sizes(i)(0) & " to " & sizes(i)(1)
    Next i

    Set sizes = Bounds(B)
    Debug.Print vbCrLf & "B has " & sizes.Count & " dimensions:"
    For i = 1 To sizes.Count
        Debug.Print sizes(i)(0) & " to " & sizes(i)(1)
    Next i

    Set sizes = Bounds(C)
    Debug.Print vbCrLf & "C has " & sizes.Count & " dimensions:"
    For i = 1 To sizes.Count
        Debug.Print sizes(i)(0) & " to " & sizes(i)(1)
    Next i
End Sub

Output:

A has 3 dimensions:
1 to 10
1 to 5
4 to 10

B has 1 dimensions:
1 to 5

C has 0 dimensions:

AngularJS form elements look for the required attribute to perform validation functions. ng-required allows you to set the required attribute depending on a boolean test (for instance, only require field B - say, a student number - if the field A has a certain value - if you selected "student" as a choice)

As an example, <input required> and <input ng-required="true"> are essentially the same thing

If you are wondering why this is this way, (and not just make <input required="true"> or <input required="false">), it is due to the limitations of HTML - the required attribute has no associated value - its mere presence means (as per HTML standards) that the element is required - so angular needs a way to set/unset required value (required="false" would be invalid HTML)

To force the download of a PDF file, instead of being handled by the browser's PDF plugin:

public ActionResult DownloadPDF()
{
    return File("~/Content/MyFile.pdf", "application/pdf", "MyRenamedFile.pdf");
}

If you want to let the browser handle by its default behavior (plugin or download), just send two parameters.

public ActionResult DownloadPDF()
{
    return File("~/Content/MyFile.pdf", "application/pdf");
}

You'll need to use the third parameter to specify a name for the file on the browser dialog.

UPDATE: Charlino is right, when passing the third parameter (download filename) Content-Disposition: attachment; gets added to the Http Response Header. My solution was to send application\force-download as the mime-type, but this generates a problem with the filename of the download so the third parameter is required to send a good filename, therefore eliminating the need to force a download.

An Activity is a user interface component that are mainly used to construct a single screen of application, and represents the main focus of attention on a screen.

In contrast, Fragments, introduced in Honeycomb(3.0) as tablets emerged with larger screens, are reusable components that are attached to and displayed within activities.

Fragments must be hosted by an activity and an activity can host one or more fragments at a time. And a fragment’s lifecycle is directly affected by its host activity’s lifecycle.

While it’s possible to develop a UI only using Activities, this is generally a bad idea since their code cannot later be reused within other Activities, and cannot support multiple screens. In contrast, these are advantages that come with the use of Fragments: optimized experiences based on device size and well-structured, reusable code.

it depends what sort of t-test you want to do (one sided or two sided dependent or independent) but it should be as simple as:

from scipy.stats import ttest_ind

cat1 = my_data[my_data['Category']=='cat1']
cat2 = my_data[my_data['Category']=='cat2']

ttest_ind(cat1['values'], cat2['values'])
>>> (1.4927289925706944, 0.16970867501294376)

it returns a tuple with the t-statistic & the p-value

see here for other t-tests http://docs.scipy.org/doc/scipy/reference/stats.html

My issue is a little different, I need to switch from one childViewController in 1st tabBar to home viewController of 2nd tabBar. I simply use the solution provided in the upstairs:

tabBarController.selectedIndex = 2

However when it switched to the home page of 2nd tabBar, the content is invisible. And when I debug, viewDidAppear, viewWillAppear, viewDidLoad, none of them is called. My solutions is to add the following code in the UITabBarController:

override var shouldAutomaticallyForwardAppearanceMethods: Bool 
{
    return true
}

Use this:

if(typeof(String.prototype.trim) === "undefined")
{
    String.prototype.trim = function() 
    {
        return String(this).replace(/^\s+|\s+$/g, '');
    };
}

The trim function will now be available as a first-class function on your strings. For example:

" dog".trim() === "dog" //true

EDIT: Took J-P's suggestion to combine the regex patterns into one. Also added the global modifier per Christoph's suggestion.

Took Matthew Crumley's idea about sniffing on the trim function prior to recreating it. This is done in case the version of JavaScript used on the client is more recent and therefore has its own, native trim function.

If you just want to change the legend title, you can do the following:

import seaborn as sns
import matplotlib.pyplot as plt
tips = sns.load_dataset("tips")

g = sns.lmplot(
    x="total_bill", 
    y="tip", 
    hue="smoker", 
    data=tips,  
    legend=True
)

g._legend.set_title("New Title")

If you're working on the CLI and only have one flask app/process running (or rather, you just want want to kill any flask process running on your system), you can kill it with:

kill $(pgrep -f flask)

I found the log file at /usr/local/var/log/postgres.log on a mac installation from brew.

You can Publish the Solution with desired path by below code, Here PublishInDFolder is the name that has the path where we need to publish(we need to create this in below pic)

You can create publish file like this

Add below 2 lines of code in batch file(.bat)

@echo OFF 
call "C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\Tools\VsMSBuildCmd.bat"
MSBuild.exe  D:\\Solution\\DataLink.sln /p:DeployOnBuild=true /p:PublishProfile=PublishInDFolder
pause

You don't need to delete objects in java. When there is no reference to an object, it will be collected by the garbage collector automatically.

That also resolved my issue.

In case anyone would be searching - I created utility for automated import of xlsx files into google spreadsheet: xls2sheets. One can do it automatically via setting up the cronjob for ./cmd/sheets-refresh, readme describes it all. Hope that would be of use.

var url = location.href;_x000D_
var newurl = url.replace('some-domain.com','another-domain.com';);_x000D_
location.href=newurl;

You can use a constraintLayout and add the following property in the xml,

Remove docs reference

if (err) {
    return res.json(500);
}
Project.populate(docs, options, function (err, projects) {
    res.json(projects);

This worked for me.

if (err) {
    return res.json(500);
}
Project.populate(options, function (err, projects) {
    res.json(projects);
});

I've just noticed something while researching this after getting help with https.request for post method. Thought I share some input to help understand.

process.stdout.write doesn't add a new line while console.log does, like others had mentioned. But there's also this which is easier to explain with examples.

var req = https.request(options, (res) => {
    res.on('data', (d) => {
        process.stdout.write(d);
        console.log(d)
    });
});

process.stdout.write(d); will print the data properly without a new line. However console.log(d) will print a new line but the data won't show correctly, giving this <Buffer 12 34 56... for example.

To make console.log(d) show the information correctly, I would have to do this.

var req = https.request(options, (res) => {
    var dataQueue = "";    
    res.on("data", function (d) {
        dataQueue += d;
    });
    res.on("end", function () {
        console.log(dataQueue);
    });
});

So basically:

• process.stdout.write continuously prints the information as the data being retrieved and doesn't add a new line.

• console.log prints the information what was obtained at the point of retrieval and adds a new line.

That's the best way I can explain it.

java.time

While I am a fan of Joda-Time, Java 8 introduces the java.time package which is finally a worthwhile Java standard solution! Read this article, Java SE 8 Date and Time, for a good amount of information on java.time outside of hours and minutes.

In particular, look at the LocalDateTime class.

Hours and minutes:

LocalDateTime.now().getHour();
LocalDateTime.now().getMinute();

I have to work in tcsh, and I know this is not an elegant solution, but for example, if I had to change folders to a path where one word is different, the whole thing can be done in the alias

a alias_name 'set a = `pwd`; set b = `echo $a | replace "Trees" "Tests"` ; cd $b'

If the path is always fixed, the just

a alias_name2 'cd path/you/always/need'

should work In the line above, the new folder path is set

I believe this can solve app.use(express.json());

Install Fiddler on your PC and use it as a proxy on your Android device.

From RFC 4918 (and also documented at http://www.iana.org/assignments/http-status-codes/http-status-codes.xhtml):

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415 (Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

GitHub now supports closing a pull request

Basically, you need to do the following steps:

1. Visit the pull request page
2. Click on the pull request
3. Click the "close pull request" button

Example (button on the very bottom):

This way the pull request gets closed (and ignored), without merging it.

A three line solution, but works quite well:

int[] source_array = {0,1,2,3,4,5,6,7,8,9,10,11};
ArrayList<Integer> target_list = new ArrayList<Integer>();
for(int i = 0; i < source_array.length; i++){
    target_list.add(random_array[i]);
}

I can see a number of reasons:

Readability

string s = string.Format("Hey, {0} it is the {1}st day of {2}.  I feel {3}!", _name, _day, _month, _feeling);

vs:

string s = "Hey," + _name + " it is the " + _day + "st day of " + _month + ".  I feel " + feeling + "!";

Format Specifiers (and this includes the fact you can write custom formatters)

string s = string.Format("Invoice number: {0:0000}", _invoiceNum);

vs:

string s = "Invoice Number = " + ("0000" + _invoiceNum).Substr(..... /*can't even be bothered to type it*/)

String Template Persistence

What if I want to store string templates in the database? With string formatting:

_id         _translation
  1         Welcome {0} to {1}.  Today is {2}.
  2         You have {0} products in your basket.
  3         Thank-you for your order.  Your {0} will arrive in {1} working days.

vs:

_id         _translation
  1         Welcome
  2         to
  3         .  Today is
  4         . 
  5         You have
  6         products in your basket.
  7         Someone
  8         just shoot
  9         the developer.

I think flatMap() is what you're looking for.

For example:

 List<AClass> allTheObjects = map.values()
         .stream()
         .flatMap(listContainer -> listContainer.lst.stream())
         .collect(Collectors.toList());

This is the correct solution for finding a function:

SELECT name, create_date, modify_date
FROM sys.objects
WHERE type = 'fn'
AND name = 'fn_NAME'

I got a gnarly beast working with only the Microsoft Windows SDK v7.1 batch file SetEnv.Cmd -- ie: I do not have Visual Studio vAny installed and did not have to use any of the specially prepared cmd prompts (where vsvars32.bat et al rear their ugly heads). I just have the Microsoft Windows SDK for Windows 7 (7.1) installed with their C/C++ compilers. On my Xp64 box, this is the sequence I used to be able to compile one of the June 2010 DirectX SDK Audio samples :

REM open a regular old cmd.exe and run these 3
REM this builds the Win32 (ie: x86) version of the exe

cd "C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Samples\C++\XACT\Tutorials\Tut02_Stream"

"C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.Cmd" /debug /x86 /xp

"C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe" Tut02_Stream_2010.sln /p:Configuration=Debug /p:Platform=Win32

Note that using the Framework64 version of MSBuild.exe prevents me from building the X64 version (due to targets?), but the X86 version of MSBuild successfully built the X64 version of the same tutorial exe:

REM open a regular old cmd.exe and run these 3
REM this builds the X64 version of the exe

cd "C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Samples\C++\XACT\Tutorials\Tut02_Stream"

"C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.Cmd" /debug /x64 /2003

"C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe" Tut02_Stream_2010.sln /p:Configuration=Debug /p:Platform=X64

Put this formula in cell d31 and copy down to d39

 =iferror(vlookup(b31,$f$3:$g$12,2,0),"")

Here's what is going on. VLOOKUP:

• Takes a value (here the contents of b31),
• Looks for it in the first column of a range (f3:f12 in the range f3:g12), and
• Returns the value for the corresponding row in a column in that range (in this case, the 2nd column or g3:g12 of the range f3:g12).

As you know, the last argument of VLOOKUP sets the match type, with FALSE or 0 indicating an exact match.

Finally, IFERROR handles the #N/A when VLOOKUP does not find a match.

I got the error "The table/view 'dbo.vMyView' does not have a primary key defined" after I created a view in SQL server query designer. I solved the problem by using ISNULL on a column to force entity framework to use it as a primary key. You might have to restart visual studio to get the warnings to go away.

CREATE VIEW [dbo].[vMyView]
AS
SELECT ISNULL(Id, -1) AS IdPrimaryKey, Name
FROM  dbo.MyTable

Sometimes it is possible to solve it in the model like this: Suppose you have 3 boolean properties OptionA, OptionB, OptionC.

XAML:

<RadioButton IsChecked="{Binding OptionA}"/>
<RadioButton IsChecked="{Binding OptionB}"/>
<RadioButton IsChecked="{Binding OptionC}"/>

CODE:

private bool _optionA;
public bool OptionA
{
    get { return _optionA; }
    set
    {
        _optionA = value;
        if( _optionA )
        {
             this.OptionB= false;
             this.OptionC = false;
        }
    }
}

private bool _optionB;
public bool OptionB
{
    get { return _optionB; }
    set
    {
        _optionB = value;
        if( _optionB )
        {
            this.OptionA= false;
            this.OptionC = false;
        }
    }
}

private bool _optionC;
public bool OptionC
{
    get { return _optionC; }
    set
    {
        _optionC = value;
        if( _optionC )
        {
            this.OptionA= false;
            this.OptionB = false;
        }
    }
}

You get the idea. Not the cleanest thing, but easy.

This XML file does not appear to have any style information associated with it. The document tree is shown below.

You will get this error in the client side when the client (the webbrowser) for some reason interprets the HTTP response content as text/xml instead of text/html and the parsed XML tree doesn't have any XML-stylesheet. In other words, the webbrowser incorrectly parsed the retrieved HTTP response content as XML instead of as HTML due to the wrong or missing HTTP response content type.

In case of JSF/Facelets files which have the default extension of .xhtml, that can in turn happen if the HTTP request hasn't invoked the FacesServlet and thus it wasn't able to parse the Facelets file and generate the desired HTML output based on the XHTML source code. Firefox is then merely guessing the HTTP response content type based on the .xhtml file extension which is in your Firefox configuration apparently by default interpreted as text/xml.

You need to make sure that the HTTP request URL, as you see in browser's address bar, matches the <url-pattern> of the FacesServlet as registered in webapp's web.xml, so that it will be invoked and be able to generate the desired HTML output based on the XHTML source code. If it's for example *.jsf, then you need to open the page by /some.jsf instead of /some.xhtml. Alternatively, you can also just change the <url-pattern> to *.xhtml. This way you never need to fiddle with virtual URLs.

See also:

• JSF Facelets: Sometimes I see the URL is .jsf and sometimes .xhtml. Why?

Note thus that you don't actually need a XML stylesheet. This all was just misinterpretation by the webbrowser while trying to do its best to make something presentable out of the retrieved HTTP response content. It should actually have retrieved the properly generated HTML output, Firefox surely knows precisely how to deal with HTML content.

You can use array_walk to apply your preg_match function to each element of the array.

http://us3.php.net/array_walk

You are lucky that you didn't complete the rebase, so you can still do git rebase --abort. If you had completed the rebase (it rewrites history), things would have been much more complex. Consider tagging the tips of branches before doing potentially damaging operations (particularly history rewriting), that way you can rewind if something blows up.

In your controller, render the new action from your create action if validation fails, with an instance variable, @car populated from the user input (i.e., the params hash). Then, in your view, add a logic check (either an if block around the form or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car is set.

for(n in 1:5) {
  if(n==3) next # skip 3rd iteration and go to next iteration
  cat(n)
}

I solved it using the following:

foreach (var image in images)
{
    iTextSharp.text.Image pic = iTextSharp.text.Image.GetInstance(image, System.Drawing.Imaging.ImageFormat.Jpeg);

    if (pic.Height > pic.Width)
    {
        //Maximum height is 800 pixels.
        float percentage = 0.0f;
        percentage = 700 / pic.Height;
        pic.ScalePercent(percentage * 100);
    }
    else
    {
        //Maximum width is 600 pixels.
        float percentage = 0.0f;
        percentage = 540 / pic.Width;
        pic.ScalePercent(percentage * 100);
    }

    pic.Border = iTextSharp.text.Rectangle.BOX;
    pic.BorderColor = iTextSharp.text.BaseColor.BLACK;
    pic.BorderWidth = 3f;
    document.Add(pic);
    document.NewPage();
}

I had the same error message, but these answers did not help. On a 4.3 nexus 7, I was using a user who was NOT the owner. I had uninstalled the older version but I kept getting the same message.

Solution: I had to login as the owner and go to Settings -> Apps, then swipe to the All tab. Scroll down to the very end of the list where the old versions are listed with a mark 'not installed'. Select it and press the 'settings' button in the top right corner and finally 'uninstall for all users'

class Base
{
    struct FooSecurity{};
};

template<class Type>
class Foo
{
    typename Type::FooSecurity If_You_Are_Reading_This_You_Tried_To_Create_An_Instance_Of_Foo_For_An_Invalid_Type;
};

Make sure derived classes inherit the FooSecurity structure and the compiler will get upset in all the right places.

If your collections object is a list, I would use the sort method, as proposed in the other answers.

However, if it is not a list, and you don't really care about what type of Collection object is returned, I think it is faster to create a TreeSet instead of a List:

TreeSet sortedSet = new TreeSet(myComparator);
sortedSet.addAll(myCollectionToBeSorted);

df.set_index('Mid').reset_index()

seems to be a pretty easy way about this.

Try --allow-unrelated-histories

It is simplified a lot in version Java 8. I have given some util methods below.

To get the day of the month in the format of int for the given day, month, and year.

    public static int findDay(final int month, final int day, final int year) {
        // System.out.println(LocalDate.of(year, month, day).getDayOfMonth());
        return LocalDate.of(year, month, day).getDayOfMonth();
    }

To get current day of the month in the format of int.

    public static int findDay(final int month, final int day, final int year) {
        // System.out.println(LocalDate.now(ZoneId.of("Asia/Kolkata")).getDayOfMonth());
        return LocalDate.now(ZoneId.of("Asia/Kolkata")).getDayOfMonth();
    }

To get the day of the week in the format of String for the given day, month, and year.

    public static String findDay(final int month, final int day, final int year) {
        // System.out.println(LocalDate.of(year, month, day).getDayOfWeek());
        return LocalDate.of(year, month, day).getDayOfWeek().toString();
    }

To get current day of the week in the format of String.

    public static String findDay(final int month, final int day, final int year) {
        // System.out.println(LocalDate.now(ZoneId.of("Asia/Kolkata"))..getDayOfWeek());
        return LocalDate.now(ZoneId.of("Asia/Kolkata")).getDayOfWeek().toString();
    }

This works for basic expressions

const nameof = exp => exp.toString().match(/[.](\w+)/)[1];

Example

nameof(() => options.displaySize);

Snippet:

var nameof = function (exp) { return exp.toString().match(/[.](\w+)/)[1]; };_x000D_
var myFirstName = 'Chuck';_x000D_
var varname = nameof(function () { return window.myFirstName; });_x000D_
console.log(varname);

Regards

Aside from readability and performance, one aspect commonly overlooked is consistency. There are many ways to implement a for (or while) loop over iterators, from:

for (C::iterator iter = c.begin(); iter != c.end(); iter++) {
    do_something(*iter);
}

to:

C::iterator iter = c.begin();
C::iterator end = c.end();
while (iter != end) {
    do_something(*iter);
    ++iter;
}

with many examples in between at varying levels of efficiency and bug potential.

Using for_each, however, enforces consistency by abstracting away the loop:

for_each(c.begin(), c.end(), do_something);

The only thing you have to worry about now is: do you implement the loop body as function, a functor, or a lambda using Boost or C++0x features? Personally, I'd rather worry about that than how to implement or read a random for/while loop.

Since it's C++ why not to use std::string instead of char*? Concatenation will be trivial:

std::string str = "abc";
str += "another";

Here my regexp for validate string:

^\"([^\"\\]*|\\(["\\\/bfnrt]{1}|u[a-f0-9]{4}))*\"$

Was written usign original syntax diagramm.

Please take a good look here: http://jquerymobile.com/test/docs/api/methods.html

$.mobile.changePage() is to change from one page to another, and the parameter can be a url or a page object. ( only #result will also work )

$.mobile.page() isn't recommended anymore, please use .trigger( "create"), see also: JQuery Mobile .page() function causes infinite loop?

Important: Create vs. refresh: An important distinction

Note that there is an important difference between the create event and refresh method that some widgets have. The create event is suited for enhancing raw markup that contains one or more widgets. The refresh method that some widgets have should be used on existing (already enhanced) widgets that have been manipulated programmatically and need the UI be updated to match.

For example, if you had a page where you dynamically appended a new unordered list with data-role=listview attribute after page creation, triggering create on a parent element of that list would transform it into a listview styled widget. If more list items were then programmatically added, calling the listview’s refresh method would update just those new list items to the enhanced state and leave the existing list items untouched.

$.mobile.refresh() doesn't exist i guess

So what are you using for your results? A listview? Then you can update it by doing:

$('ul').listview('refresh');

Example: http://operationmobile.com/dont-forget-to-call-refresh-when-adding-items-to-your-jquery-mobile-list/

Otherwise you can do:

$('#result').live("pageinit", function(){ // or pageshow
    // your dom manipulations here
});

Map is an interface; HashMap is a particular implementation of that interface.

HashMap uses a collection of hashed key values to do its lookup. TreeMap will use a red-black tree as its underlying data store.

Specifying a max-width or fixed width doesn't work for all situations, and the table should be fluid and auto-space its cells. That's what tables are for. Works on IE9 and other browsers.

The Rails Active Support gem provides upcase, downcase, swapcase,capitalize, etc. methods with internationalization support:

gem install activesupport
irb -ractive_support/core_ext/string
"STRING  ÁÂÃÀÇÉÊÍÓÔÕÚ".mb_chars.downcase.to_s
 => "string  áâãàçéêíóôõú"
"string  áâãàçéêíóôõú".mb_chars.upcase.to_s
=> "STRING  ÁÂÃÀÇÉÊÍÓÔÕÚ"

Well, there are methods could be called "inline" methods in java, but depending on the jvm. After compiling, if the method's machine code is less than 35 byte, it will be transferred to a inline method right away, if the method's machine code is less than 325 byte, it could be transferred into a inline method, depending on the jvm.

Can't be sure if this applied to SQL Server Express, but you can still access the "before" data even if your trigger is happening AFTER the update. You need to read the data from either the deleted or inserted table that is created on the fly when the table is changed. This is essentially what @Stamen says, but I still needed to explore further to understand that (helpful!) answer.

The deleted table stores copies of the affected rows during DELETE and UPDATE statements. During the execution of a DELETE or UPDATE statement, rows are deleted from the trigger table and transferred to the deleted table...

The inserted table stores copies of the affected rows during INSERT and UPDATE statements. During an insert or update transaction, new rows are added to both the inserted table and the trigger table...

https://msdn.microsoft.com/en-us/library/ms191300.aspx

So you can create your trigger to read data from one of those tables, e.g.

CREATE TRIGGER <TriggerName> ON <TableName>
AFTER UPDATE
AS
  BEGIN
    INSERT INTO <HistoryTable> ( <columns...>, DateChanged )
    SELECT <columns...>, getdate()
    FROM deleted;
  END;

My example is based on the one here:

sql-server triggers

Don't declare the variable in the userform. Declare it as Public in the module.

Public pass As String

In the Userform

Private Sub CommandButton1_Click()
    pass = UserForm1.TextBox1
    Unload UserForm1
End Sub

In the Module

Public pass As String

Public Sub Login()
    '
    '~~> Rest of the code
    '
    UserForm1.Show
    driver.findElementByName("PASSWORD").SendKeys pass
    '
    '~~> Rest of the code
    '
End Sub

You might want to also add an additional check just before calling the driver.find... line?

If Len(Trim(pass)) <> 0 Then

This will ensure that a blank string is not passed.

I use the below code which is more intuitive.

int countSetBits(int n) {
    return !n ? 0 : 1 + countSetBits(n & (n-1));
}

Logic : n & (n-1) resets the last set bit of n.

P.S : I know this is not O(1) solution, albeit an interesting solution.

Download and install from http://www.microsoft.com/en-us/download/details.aspx?id=34595. You need Windows 7 SP1 though.

It's worth keeping in mind that PowerShell 3 on Windows 7 does not have all the cmdlets as PowerShell 3 on Windows 8. So you may still encounter cmdlets that are not present on your system.

There WHERE part could be written like this:

WHERE 
 (LEN('TestPerson') <> 0 OR co.personentered  = co.personentered) AND
 (LEN('TestPerson') = 0 OR co.personentered LIKE '%TestPerson') AND
 (cc.ccnum = CASE LEN('TestFFNum')
                WHEN 0 THEN cc.ccnum 
                ELSE 'TestFFNum' 
              END ) AND
 (LEN('2011-01-09 11:56:29.327') <> 0 OR co.DTEntered = co.DTEntered ) AND

 tl.storenum < 699 

var firstFiveItems = myList.Take(5);

Or to slice:

var secondFiveItems = myList.Skip(5).Take(5);

And of course often it's convenient to get the first five items according to some kind of order:

var firstFiveArrivals = myList.OrderBy(i => i.ArrivalTime).Take(5);

Use different format or pattern to get the information from the date

var myDate = new Date("2015-06-17 14:24:36");_x000D_
console.log(moment(myDate).format("YYYY-MM-DD HH:mm:ss"));_x000D_
console.log("Date: "+moment(myDate).format("YYYY-MM-DD"));_x000D_
console.log("Year: "+moment(myDate).format("YYYY"));_x000D_
console.log("Month: "+moment(myDate).format("MM"));_x000D_
console.log("Month: "+moment(myDate).format("MMMM"));_x000D_
console.log("Day: "+moment(myDate).format("DD"));_x000D_
console.log("Day: "+moment(myDate).format("dddd"));_x000D_
console.log("Time: "+moment(myDate).format("HH:mm")); // Time in24 hour format_x000D_
console.log("Time: "+moment(myDate).format("hh:mm A"));

Well, its not compulsory to restart the emulator you can also reset adb from eclipse itself.

1.) Go to DDMS and there is a reset adb option, please see the image below.

2.) You can restart adb manually from command prompt

  run->cmd->your_android_sdk_path->platform-tools>

Then write the below commands.

adb kill-server - To kill the server forcefully

adb start-server - To start the server

UPDATED:

F:\android-sdk-windows latest\platform-tools>adb kill-server

F:\android-sdk-windows latest\platform-tools>adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *

Easiest way for me is to Insert Markup.

Then in text box type the text between curly braces.

It will insert the formatted text in a new line but you can copy it anywhere, even inline.

Make sure you image is a relative path such as:

@Url.Content("~/Content/images/myimage.png")

MVC4

<img src="~/Content/images/myimage.png" />

You could convert the byte[] into a Base64 string on the fly.

string base64String = Convert.ToBase64String(imageBytes);

<img src="@String.Format("data:image/png;base64,{0}", base64string)" />

please modify your router.module.ts as:

const routes: Routes = [
{
    path: '',
    redirectTo: 'one',
    pathMatch: 'full'
},
{
    path: 'two',
    component: ClassTwo, children: [
        {
            path: 'three',
            component: ClassThree,
            outlet: 'nameThree',
        },
        {
            path: 'four',
            component: ClassFour,
            outlet: 'nameFour'
        },
        {
           path: '',
           redirectTo: 'two',
           pathMatch: 'full'
        }
    ]
},];

and in your component1.html

<h3>In One</h3>

<nav>
    <a routerLink="/two" class="dash-item">...Go to Two...</a>
    <a routerLink="/two/three" class="dash-item">... Go to THREE...</a>

UPDATE tbl_ClientNotes 
SET ordering=@ordering, title=@title, content=@content

Or if you meant you only want to update individual columns you would use the post above mine. I read it as do not update if any values are null

Take a look at OAuth 2.0 playground.You will get an overview of the protocol.It is basically an environment(like any app) that shows you the steps involved in the protocol.

https://developers.google.com/oauthplayground/

The object name is not very important. what you should be focusing at is the variable that stores the lineedit object (le) and your pushbutton object(pb)

QObject(self.pb, SIGNAL("clicked()"), self.button_clicked)

def button_clicked(self):
  self.le.setText("shost")

I think this is what you want. I hope i got your question correctly :)

I used a version of os.walk and on a larger directory got times around 3.5 sec. I tried two random solutions with no great improvement, then just did:

paths = [line[2:] for line in subprocess.check_output("find . -iname '*.txt'", shell=True).splitlines()]

While it's POSIX-only, I got 0.25 sec.

From this, I believe it's entirely possible to optimise whole searching a lot in a platform-independent way, but this is where I stopped the research.

// this is the dataSource
this.guests = [];

this.guests.push({id: 1, name: 'Ricardo'});

// refresh the dataSource this.guests = Array.from(this.guest);

I used the code for the original basicAuth to find the answer:

app.use(function(req, res, next) {
    var user = auth(req);

    if (user === undefined || user['name'] !== 'username' || user['pass'] !== 'password') {
        res.statusCode = 401;
        res.setHeader('WWW-Authenticate', 'Basic realm="MyRealmName"');
        res.end('Unauthorized');
    } else {
        next();
    }
});

In my case, I was looking for a keydown ctrl key and click event. My jquery looks like this:

$('.linkAccess').click( function (event) {
  if(true === event.ctrlKey) {

    /* Extract the value */
    var $link = $('.linkAccess');
    var value = $link.val();

    /* Verified if the link is not null */
    if('' !== value){
      window.open(value);
    }
  }
});

Where "linkAccess" is the class name for some specific fields where I have a link and I want to access it using my combination of key and click.

A var cannot be set to null since it needs to be statically typed.

var foo = null;
// compiler goes: "Huh, what's that type of foo?"

However, you can use this construct to work around the issue:

var foo = (string)null;
// compiler goes: "Ah, it's a string. Nice."

I don't know for sure, but from what I heard you can also use dynamic instead of var. This does not require static typing.

dynamic foo = null;
foo = "hi";

Also, since it was not clear to me from the question if you meant the varkeyword or variables in general: Only references (to classes) and nullable types can be set to null. For instance, you can do this:

string s = null; // reference
SomeClass c = null; // reference
int? i = null; // nullable

But you cannot do this:

int i = null; // integers cannot contain null

I had this issue and I fixed it using the following steps You need to completely uninstall python3-p using:

sudo apt-get --purge autoremove python3-pip

Then resintall the package with:

 sudo apt install python3-pip

To confirm that everything works, run:

 pip3 -V

After this you can now use pip3 to manage any python package of your interest. Eg

pip3 install NumPy

{{ word|striptags('<b>,<a>,<pre>')|raw }}

if you want to allow multiple tags

I know this has been said earlier, but jQuery Autocomplete will do exactly what you need. You should check out the docs as the autocomplete is very customizable. If you are familiar with javascript then you should be able to work this out. If not I can give you a few pointers, as I have done this once before, but beware I am not well versed in javascript myself either, so bear with me on this.

I think the first thing you should do is just get a simple autocomplete text field working on your page, and then you can customize it from there.

The autocomplete widget accepts JSON data as it's 'source:' option. So you should set-up your app to produce the 20 top level categories, and subcategories in JSON format.

The next thing to know is that when the user types into your textfield, the autocomplete widget will send the typed values in a parameter called "term".

So let's say you first set-up your site to deliver the JSON data from a URL like this:

/categories.json

Then your autocomplete source: option would be 'source: /categories.json'.

When a user types into the textfield, such as 'first-cata...' the autocomplete widget will start sending the value in the 'term' parameter like this:

/categories.json?term=first-cata

This will return JSON data back to the widget filtered by anything that matches 'first-cata', and this is displayed as an autocomplete suggestion.

I am not sure what you are programming in, but you can specify how the 'term' parameter finds a match. So you can customize this, so that the term finds a match in the middle of a word if you want. Example, if the user types 'or' you code could make a match on 'sports'.

Lastly, you made a comment that you want to be able to select a category name but have the autocomplete widget submit the category ID not the name.

This can easily be done with a hidden field. This is what is shown in the jQuery autocomplete docs.

When a user selects a category, your JavaScript should update a hidden field with the ID.

I know this answer is not very detailed, but that is mainly because I am not sure what you are programming in, but the above should point you in the right direction. The thing to know is that you can do practically any customizing you want with this widget, if you are willing to spend the time to learn it.

These are the broad strokes, but you can look here for some notes I made when I implemented something similar to what you want in a Rails app.

Hope this helped.

You can 'learn' the size of the array automatically:

template<typename T, size_t N>
void set_data(const T (&w)[N]){
    w_.assign(w, w+N);
}

Hopefully, you can change the interface to set_data as above. It still accepts a C-style array as its first argument. It just happens to take it by reference.

How it works

[ Update: See here for a more comprehensive discussion on learning the size ]

Here is a more general solution:

template<typename T, size_t N>
void copy_from_array(vector<T> &target_vector, const T (&source_array)[N]) {
    target_vector.assign(source_array, source_array+N);
}

This works because the array is being passed as a reference-to-an-array. In C/C++, you cannot pass an array as a function, instead it will decay to a pointer and you lose the size. But in C++, you can pass a reference to the array.

Passing an array by reference requires the types to match up exactly. The size of an array is part of its type. This means we can use the template parameter N to learn the size for us.

It might be even simpler to have this function which returns a vector. With appropriate compiler optimizations in effect, this should be faster than it looks.

template<typename T, size_t N>
vector<T> convert_array_to_vector(const T (&source_array)[N]) {
    return vector<T>(source_array, source_array+N);
}
