So the package will be downloaded in a temp folder C:\Users\U122337.BOSTONADVISORS\AppData\Local\Temp\Rtmp404t8Y\downloaded_packages from where it will be installed into your library folder, e.g. C:\R\library\zoo

What you have to do once install command is done: Open Packages menu -> Load package...

You will see your package on the list. You can automate this: How to load packages in R automatically?

Using anytime package:

library(anytime)

anydate("2009-01")
# [1] "2009-01-01"

Having had a similar problem with data from 1800 to now, this worked for me:

data2$date=as.character(data2$date) 
lct <- Sys.getlocale("LC_TIME"); 
Sys.setlocale("LC_TIME","C")
data2$date<- as.Date(data2$date, format = "%Y %m %d") # and it works

I think, below procedure help you to what you are looking for.

 CREATE PROCEDURE [dbo].[FindEmployeeRecord]
        @EmployeeID nvarchar(Max)
    AS
    BEGIN
    DECLARE @sqLQuery VARCHAR(MAX)
    Declare @AnswersTempTable Table
    (  
        EmpId int,         
        EmployeeName nvarchar (250),       
        EmployeeAddress nvarchar (250),  
        PostalCode nvarchar (50),
        TelephoneNo nvarchar (50),
        Email nvarchar (250),
        status nvarchar (50),  
        Sex nvarchar (50) 
    )

    Set @sqlQuery =
    'select e.EmpId,e.EmployeeName,e.Email,e.Sex,ed.EmployeeAddress,ed.PostalCode,ed.TelephoneNo,ed.status
    from Employee e
    join EmployeeDetail ed on e.Empid = ed.iEmpID
    where Convert(nvarchar(Max),e.EmpId) in ('+@EmployeeId+')
    order by EmpId'
    Insert into @AnswersTempTable
    exec (@sqlQuery)
    select * from @AnswersTempTable
    END

Copy the file into your src folder. Go to the Project Explorer in Eclipse, Right-click on your project, and click on "Refresh". The file should appear on the Project Explorer pane as well.

I would like to expand the answer of Jason Bunting

like this

ActionResult action = new SampelController().Index(2, "text");
return action;

And Eli will be here for something idea on how to make it generic variable

Can get all types of controller

  <form>     
            <div class="form-group">
                <label for="nameLabel">Name</label>
                <input id="name" name="name" class="form-control" type="text" /> 
            </div>
            <div class="form-group">
                <label for="PhoneLabel">Phone</label>
                <input id="phone" name="phone" class="form-control" type="text" /> 
            </div>
            <div class="form-group">
                <label for="yearLabel">Year</label>
                <input id="year" name="year" class="form-control" type="text" />
            </div>
        </form>

Easier method is window.location.href = "http://example.com/new_url";

But what if you want to check if username and password whether empty or not using JavaScript and send it to the php to check whether user in the database. You can do this easily following this code.

html form -

<form name="myForm" onsubmit="return validateForm()" method="POST" action="login.php" >         
    <input type="text" name="username" id="username" />
    <input type="password" name="password" id="password" />
    <input type="submit" name="submitBt"value="LogIn" />
</form>

javascript validation-

function validateForm(){
    var uname = document.forms["myForm"]["username"].value;
    var pass = document.forms["myForm"]["password"].value;

    if((!isEmpty(uname, "Log In")) && (!isEmpty(pass, "Password"))){

        return true;
    }else{
        return false;
    }
}

function isEmpty(elemValue, field){
    if((elemValue == "") || (elemValue == null)){
        alert("you can not have "+field+" field empty");
        return true;
    }else{
        return false;
    }
}

check if user in the database using php

<?php
    $con = mysqli_connect("localhost","root","1234","users");

    if(mysqli_connect_errno()){
        echo "Couldn't connect ".mysqli_connect_error();
    }else{
        //echo "connection successful <br />";
    }

    $uname_tb = $_POST['username'];
    $pass_tb = $_POST['password'];

    $query ="SELECT * FROM user";
    $result = mysqli_query($con,$query);

    while($row = mysqli_fetch_array($result)){
        if(($row['username'] == $uname_tb) && ($row['password'] == $pass_tb)){
            echo "Login Successful";
            header('Location: dashbord.php');
            exit();
        }else{
            echo "You are not in our database".mysqli_connect_error();
        }
    }
    mysqli_close($con);
?>

Simply:

$("#tabs_div").tabs();
$("#tabs_div").on("click", "a.tab_a", function(){
    console.log("selected tab id: " + $(this).attr("href"));
    console.log("selected tab name: " + $(this).find("span").text());
});

But you have to add class name to your anchors named "tab_a":

<div id="tabs">
<UL>
    <LI><A class="tab_a" href="#fragment-1"><SPAN>Tab1</SPAN></A></LI>
    <LI><A class="tab_a" href="#fragment-2"><SPAN>Tab2</SPAN></A></LI>
    <LI><A class="tab_a" href="#fragment-3"><SPAN>Tab3</SPAN></A></LI>
    <LI><A class="tab_a" href="#fragment-4"><SPAN>Tab4</SPAN></A></LI>
</UL>

<DIV id=fragment-1>
<UL>
    <LI><A class="tab_a" href="#fragment-1a"><SPAN>Sub-Tab1</SPAN></A></LI>
    <LI><A class="tab_a" href="#fragment-1b"><SPAN>Sub-Tab2</SPAN></A></LI>
    <LI><A class="tab_a" href="#fragment-1c"><SPAN>Sub-Tab3</SPAN></A></LI>
</UL>
</DIV>
.
.
</DIV>

Here is my solution:

<!-- jquery smooth scroll to id's -->   
<script>
$(function() {
  $('a[href*=\\#]:not([href=\\#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top
        }, 500);
        return false;
      }
    }
  });
});
</script>

With just this snippet you can use an unlimited number of hash-links and corresponding ids without having to execute a new script for each.

I already explained how it works in another thread here: https://stackoverflow.com/a/28631803/4566435 (or here's a direct link to my blog post)

For clarifications, let me know. Hope it helps!

Have a look at Fuel library, a sample GET request

"https://httpbin.org/get"
  .httpGet()
  .responseString { request, response, result ->
    when (result) {
      is Result.Failure -> {
        val ex = result.getException()
      }
      is Result.Success -> {
        val data = result.get()
      }
    }
  }

// You can also use Fuel.get("https://httpbin.org/get").responseString { ... }
// You can also use FuelManager.instance.get("...").responseString { ... }

A sample POST request

Fuel.post("https://httpbin.org/post")
    .jsonBody("{ \"foo\" : \"bar\" }")
    .also { println(it) }
    .response { result -> }

Their documentation can be found here ?

If you validate , option 1 comes up as an error in html 5, so option 2 is correct.

There are a few different ways to go about it. reshape2 is a helpful package. Personally, I like using data.table

Below is a step-by-step

If myDF is your data.frame:

library(data.table)
DT <- data.table(myDF)

DT

# this will get you your mean and SD's for each column
DT[, sapply(.SD, function(x) list(mean=mean(x), sd=sd(x)))]

# adding a `by` argument will give you the groupings
DT[, sapply(.SD, function(x) list(mean=mean(x), sd=sd(x))), by=ID]

# If you would like to round the values: 
DT[, sapply(.SD, function(x) list(mean=round(mean(x), 3), sd=round(sd(x), 3))), by=ID]

# If we want to add names to the columns 
wide <- setnames(DT[, sapply(.SD, function(x) list(mean=round(mean(x), 3), sd=round(sd(x), 3))), by=ID], c("ID", sapply(names(DT)[-1], paste0, c(".men", ".SD"))))

wide

   ID Obs.1.men Obs.1.SD Obs.2.men Obs.2.SD Obs.3.men Obs.3.SD
1:  1    35.333    8.021    36.333   10.214      33.0    9.644
2:  2    29.750    3.594    32.250    4.193      30.5    5.916
3:  3    41.500    4.950    43.500    4.950      39.0    4.243

Also, this may or may not be helpful

> DT[, sapply(.SD, summary), .SDcols=names(DT)[-1]]
        Obs.1 Obs.2 Obs.3
Min.    25.00 28.00 22.00
1st Qu. 29.00 31.00 27.00
Median  33.00 32.00 36.00
Mean    34.22 36.11 33.22
3rd Qu. 38.00 40.00 37.00
Max.    45.00 48.00 42.00

Request and response.

To understand the req, try out console.log(req);.

If you want to do something with Java Strings, Commons Lang StringUtils is a great place to look.

StringUtils.remove("TextX Xto modifyX", 'X');

In my experience

http://www.example.com

worked fine But, https required /* at the end

Auto-incrementing the index in a loop:

myArr[(len(myArr)+1)]={"key":"val"}

To just get the value use any of these

1. df1.agg({"x": "max"}).collect()[0][0]
2. df1.agg({"x": "max"}).head()[0]
3. df1.agg({"x": "max"}).first()[0]

Alternatively we could do these for 'min'

from pyspark.sql.functions import min, max
df1.agg(min("id")).collect()[0][0]
df1.agg(min("id")).head()[0]
df1.agg(min("id")).first()[0]

The option that I do is by using the popular Plus Messenger on Android. The play store link is: https://play.google.com/store/apps/details?id=org.telegram.plus&hl=en

You can click on the Channel and in Channel info below the group name, you can find Channel Id.

Supergroup and Channel Ids will looks like 1068773197 on plus messenger. For your usage on API, you can prefix -100 which would make it -1001068773197.

Second Question

Will my existing implementations continue to work? If not, is there an easy to implement alternative.

The answer is yes, but not without a little work.

$.browser is an official plugin which was included in older versions of jQuery, so like any plugin you can simple copy it and incorporate it into your project or you can simply add it to the end of any jQuery release.

I have extracted the code for you incase you wish to use it.

// Limit scope pollution from any deprecated API
(function() {

    var matched, browser;

// Use of jQuery.browser is frowned upon.
// More details: http://api.jquery.com/jQuery.browser
// jQuery.uaMatch maintained for back-compat
    jQuery.uaMatch = function( ua ) {
        ua = ua.toLowerCase();

        var match = /(chrome)[ \/]([\w.]+)/.exec( ua ) ||
            /(webkit)[ \/]([\w.]+)/.exec( ua ) ||
            /(opera)(?:.*version|)[ \/]([\w.]+)/.exec( ua ) ||
            /(msie) ([\w.]+)/.exec( ua ) ||
            ua.indexOf("compatible") < 0 && /(mozilla)(?:.*? rv:([\w.]+)|)/.exec( ua ) ||
            [];

        return {
            browser: match[ 1 ] || "",
            version: match[ 2 ] || "0"
        };
    };

    matched = jQuery.uaMatch( navigator.userAgent );
    browser = {};

    if ( matched.browser ) {
        browser[ matched.browser ] = true;
        browser.version = matched.version;
    }

// Chrome is Webkit, but Webkit is also Safari.
    if ( browser.chrome ) {
        browser.webkit = true;
    } else if ( browser.webkit ) {
        browser.safari = true;
    }

    jQuery.browser = browser;

    jQuery.sub = function() {
        function jQuerySub( selector, context ) {
            return new jQuerySub.fn.init( selector, context );
        }
        jQuery.extend( true, jQuerySub, this );
        jQuerySub.superclass = this;
        jQuerySub.fn = jQuerySub.prototype = this();
        jQuerySub.fn.constructor = jQuerySub;
        jQuerySub.sub = this.sub;
        jQuerySub.fn.init = function init( selector, context ) {
            if ( context && context instanceof jQuery && !(context instanceof jQuerySub) ) {
                context = jQuerySub( context );
            }

            return jQuery.fn.init.call( this, selector, context, rootjQuerySub );
        };
        jQuerySub.fn.init.prototype = jQuerySub.fn;
        var rootjQuerySub = jQuerySub(document);
        return jQuerySub;
    };

})();

If you're asking why anyone would need a depreciated plugin, I have prepared the following answer.

First and foremost the answer is compatibility. Since jQuery is plugin based, some developers opted to use $.browser and with the latest releases of jQuery which doesn't include $.browser all those plugins where rendered useless.

jQuery did release a migration plugin, which was created for developers to detect whether their plugin's used any depreciated dependencies such as $.browser.

Although this helped developers patch their plugin's. jQuery dropped $.browser completely so the above fix is probably the only solution until your developers patch or incorporate the above.

About: jQuery.browser

I had the same issues but nothing worked. What I did was I added this to the selector:

-webkit-appearance: none;
-moz-appearance: none;
appearance: none;

I wrote this little script that takes the guess work out of the copy/paste commands.

The Linux version of the script relies on xclip being already installed in your system. The script is called clipboard.

#!/bin/bash
# Linux version
# Use this script to pipe in/out of the clipboard
#
# Usage: someapp | clipboard     # Pipe someapp's output into clipboard
#        clipboard | someapp     # Pipe clipboard's content into someapp
#

if command -v xclip 1>/dev/null; then
    if [[ -p /dev/stdin ]] ; then
        # stdin is a pipe
        # stdin -> clipboard
        xclip -i -selection clipboard
    else
        # stdin is not a pipe
        # clipboard -> stdout
        xclip -o -selection clipboard
    fi
else
    echo "Remember to install xclip"
fi

The OS X version of the script relies on pbcopy and pbpaste which are preinstalled on all Macs.

#!/bin/bash
# OS X version
# Use this script to pipe in/out of the clipboard
#
# Usage: someapp | clipboard     # Pipe someapp's output into clipboard
#        clipboard | someapp     # Pipe clipboard's content into someapp
#

if [[ -p /dev/stdin ]] ; then
    # stdin is a pipe
    # stdin -> clipboard
    pbcopy
else
    # stdin is not a pipe
    # clipboard -> stdout
    pbpaste
fi

Using the script is very simple since you simply pipe in or out of clipboard as shown in these two examples.

$ cat file | clipboard

$ clipboard | less

I know this is an old question, but how about just binding to Command if using MVVM?

ex:

<CheckBox Content="Case Sensitive" Command="{Binding bSearchCaseSensitive}"/>

For me it triggers on both Check and Uncheck.

A bit late here, but none of the above seemed to work. Try this, using printf, inserts spaces between each. I chose to not have newline at the end.

awk '{for(i=3;i<=NF;++i) printf("%s ",  $i) }'

I just made a pure Javascript function based on that code. Javascript only version demo: http://jsbin.com/copidifiji

That is the independent code from jQuery

if (window.addEventListener) {window.addEventListener('DOMMouseScroll', wheel, false); 
window.onmousewheel = document.onmousewheel = wheel;}

function wheel(event) {
    var delta = 0;
    if (event.wheelDelta) delta = (event.wheelDelta)/120 ;
    else if (event.detail) delta = -(event.detail)/3;

    handle(delta);
    if (event.preventDefault) event.preventDefault();
    event.returnValue = false;
}

function handle(sentido) {
    var inicial = document.body.scrollTop;
    var time = 1000;
    var distance = 200;
  animate({
    delay: 0,
    duration: time,
    delta: function(p) {return p;},
    step: function(delta) {
window.scrollTo(0, inicial-distance*delta*sentido);   
    }});}

function animate(opts) {
  var start = new Date();
  var id = setInterval(function() {
    var timePassed = new Date() - start;
    var progress = (timePassed / opts.duration);
    if (progress > 1) {progress = 1;}
    var delta = opts.delta(progress);
    opts.step(delta);
    if (progress == 1) {clearInterval(id);}}, opts.delay || 10);
}

You can use the fuser command, like:

fuser file_name

You will receive a list of processes using the file.

You can use different flags with it, in order to receive a more detailed output.

You can find more info in the fuser's Wikipedia article, or in the man pages.

Here is a way to do it with a closure:

    def generate_add_mult_func(func):
        def function_generator(x):
            return reduce(func,range(1,x))
        return function_generator

    def add(x,y):
        return x+y

    def mult(x,y):
        return x*y

    adding=generate_add_mult_func(add)
    multiplying=generate_add_mult_func(mult)

    print adding(10)
    print multiplying(10)

Your first example,

@collection.each do |item|
  # do whatever
end

is more idiomatic. While Ruby supports looping constructs like for and while, the block syntax is generally preferred.

Another subtle difference is that any variable you declare within a for loop will be available outside the loop, whereas those within an iterator block are effectively private.

I have used the solution from Anthony Juckel but in the MANIFEST.MF the key have to start with uppercase.

So my MANIFEST.MF file contain a key like:

Mykey: value

Then in the activator or another class you can use the code from Anthony to read the MANIFEST.MF file and the the value that you need.

// If you have a BundleContext 
Dictionary headers = bundleContext.getBundle().getHeaders();

// If you don't have a context, and are running in 4.2 
Bundle bundle = `FrameworkUtil.getBundle(this.getClass()); 
bundle.getHeaders();

On many source packages (e.g. for most GNU software), the building system may know about the DESTDIR make variable, so you can often do:

 make install DESTDIR=/tmp/myinst/
 sudo cp -va /tmp/myinst/ /

The advantage of this approach is that make install don't need to run as root, so you cannot end up with files compiled as root (or root-owned files in your build tree).

Test if your variable is an instance of numbers.Number:

>>> import numbers
>>> import decimal
>>> [isinstance(x, numbers.Number) for x in (0, 0.0, 0j, decimal.Decimal(0))]
[True, True, True, True]

This uses ABCs and will work for all built-in number-like classes, and also for all third-party classes if they are worth their salt (registered as subclasses of the Number ABC).

However, in many cases you shouldn't worry about checking types manually - Python is duck typed and mixing somewhat compatible types usually works, yet it will barf an error message when some operation doesn't make sense (4 - "1"), so manually checking this is rarely really needed. It's just a bonus. You can add it when finishing a module to avoid pestering others with implementation details.

This works starting with Python 2.6. On older versions you're pretty much limited to checking for a few hardcoded types.

Since you're using ToFileTime, you'll want to use FromFileTime to go the other way. But note:

Ordinarily, the FromFileTime method restores a DateTime value that was saved by the ToFileTime method. However, the two values may differ under the following conditions:

If the serialization and deserialization of the DateTime value occur in different time zones. For example, if a DateTime value with a time of 12:30 P.M. in the U.S. Eastern Time zone is serialized, and then deserialized in the U.S. Pacific Time zone, the original value of 12:30 P.M. is adjusted to 9:30 A.M. to reflect the difference between the two time zones.

If the DateTime value that is serialized represents an invalid time in the local time zone. In this case, the ToFileTime method adjusts the restored DateTime value so that it represents a valid time in the local time zone.

If you don't care which long representation of a DateTime is stored, you can use Ticks as others have suggested (Ticks is probably preferable, depending on your requirements, since the value returned by ToFileTime seems to be in the context of the Windows filesystem API).

for jQuery we can use below:

by input name:

$('input[name="textboxname"]').val('some value');

by input class:

$('input[type=text].textboxclass').val('some value');

by input id:

$('#textboxid').val('some value');

A .tex file should be a LaTeX source file.

If this is the case, that file contains the source code for a LaTeX document. You can open it with any text editor (notepad, notepad++ should work) and you can view the source code. But if you want to view the final formatted document, you need to install a LaTeX distribution and compile the .tex file.

Of course, any program can write any file with any extension, so if this is not a LaTeX document, then we can't know what software you need to install to open it. Maybe if you upload the file somewhere and link it in your question we can see the file and provide more help to you.

Yes, this is the source code of a LaTeX document. If you were able to paste it here, then you are already viewing it. If you want to view the compiled document, you need to install a LaTeX distribution. You can try to install MiKTeX then you can use that to compile the document to a .pdf file.

You can also check out this question and answer for how to do it: How to compile a LaTeX document?

Also, there's an online LaTeX editor and you can paste your code in there to preview the document: https://www.overleaf.com/.

The file path 'images/ip-box.png' implies that the css file is at the same level as the images folder.

It's probably more common to have 'images' and 'css' folders at the same level as the 'index.html' file.

If that were the case and the css file were one level down in its respective folder, then the path to ip-box.jpg as specified in the css file would be: '../images/ip-box.png'

ASP.NET web forms page already have a JavaScript method for handling PostBacks called "__doPostBack".

function __doPostBack(eventTarget, eventArgument) {
    if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
        theForm.__EVENTTARGET.value = eventTarget;
        theForm.__EVENTARGUMENT.value = eventArgument;
        theForm.submit();
    }
}

Use the following in your code file to generate the JavaScript that performs the PostBack. Using this method will ensure that the proper ClientID for the control is used.

protected string GetLoginPostBack()
{
    return Page.ClientScript.GetPostBackEventReference(btnLogin, string.Empty);
}

Then in the ASPX page add a javascript block.

<script language="javascript">
function btnLogin_Click() {
  <%= GetLoginPostBack() %>;
}
</script>

The final javascript will be rendered like this.

<script language="javascript">
function btnLogin_Click() {
  __doPostBack('btnLogin','');
}
</script>

Now you can use "btnLogin_Click()" from your javascript to submit the button click to the server.

Non-Unicode string data types:
Use STR for text file and VARCHAR for SQL Server columns.

Unicode string data types:
Use W_STR for text file and NVARCHAR for SQL Server columns.

The problem is that your data types do not match, so there could be a loss of data during the conversion.

Python has a language feature called List Comprehensions that is perfectly suited to making this sort of thing extremely easy. The following statement does exactly what you want and stores the result in l3:

l3 = [x for x in l1 if x not in l2]

l3 will contain [1, 6].

The InterruptedException is usually thrown when a sleep is interrupted.

The easiest would probably be tag stripping combined with replacement of some tags with text layout elements like dashes for list elements (li) and line breaks for br's and p's. It shouldn't be too hard to extend this to tables.

PDO class replaces these methods. Example for Mysql or MariaDB :

$BDD_SQL = new PDO('mysql:host='.BDD_SQL_SERVER.';dbname='.BDD_SQL_BASE.';charset=utf8', 
        BDD_SQL_LOGIN, BDD_SQL_PWD, 
        array(
          PDO::ATTR_EMULATE_PREPARES => false,
          PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION, //launch exception if error
          PDO::ATTR_DEFAULT_FETCH_MODE=> PDO::FETCH_ASSOC
                ));

Hi I know this was asked a while ago but I've just figured this out and it might help someone else. Not sure if this is exactly what you're looking for but this is how I call a stored proc and view the output using SQL Developer.
In SQL Developer when viewing the proc, right click and choose 'Run' or select Ctrl+F11 to bring up the Run PL/SQL window. This creates a template with the input and output params which you need to modify. My proc returns a sys_refcursor. The tricky part for me was declaring a row type that is exactly equivalent to the select stmt / sys_refcursor being returned by the proc:

DECLARE
  P_CAE_SEC_ID_N NUMBER;
  P_FM_SEC_CODE_C VARCHAR2(200);
  P_PAGE_INDEX NUMBER;
  P_PAGE_SIZE NUMBER;
  v_Return sys_refcursor;
  type t_row is record (CAE_SEC_ID NUMBER,FM_SEC_CODE VARCHAR2(7),rownum number, v_total_count number);
  v_rec t_row;

BEGIN
  P_CAE_SEC_ID_N := NULL;
  P_FM_SEC_CODE_C := NULL;
  P_PAGE_INDEX := 0;
  P_PAGE_SIZE := 25;

  CAE_FOF_SECURITY_PKG.GET_LIST_FOF_SECURITY(
    P_CAE_SEC_ID_N => P_CAE_SEC_ID_N,
    P_FM_SEC_CODE_C => P_FM_SEC_CODE_C,
    P_PAGE_INDEX => P_PAGE_INDEX,
    P_PAGE_SIZE => P_PAGE_SIZE,
    P_FOF_SEC_REFCUR => v_Return
  );
  -- Modify the code to output the variable
  -- DBMS_OUTPUT.PUT_LINE('P_FOF_SEC_REFCUR = ');
  loop
    fetch v_Return into v_rec;
    exit when v_Return%notfound;
    DBMS_OUTPUT.PUT_LINE('sec_id = ' || v_rec.CAE_SEC_ID || 'sec code = ' ||v_rec.FM_SEC_CODE);
  end loop;

END;

You can avoid get undefined in '$' this way

window.addEventListener("DOMContentLoaded", function(){
    // Your code
});

EDIT: Using 'DOMContentLoaded' is faster than just 'load' because load wait page fully loaded, imgs included... while DomContentLoaded waits just the structure

In short it's because:

Floating point numbers cannot represent all decimals precisely in binary

So just like 3/10 which does not exist in base 10 precisely (it will be 3.33... recurring), in the same way 1/10 doesn't exist in binary.

So what? How to deal with it? Is there any workaround?

In order to offer The best solution I can say I discovered following method:

parseFloat((0.1 + 0.2).toFixed(10)) => Will return 0.3

Let me explain why it's the best solution. As others mentioned in above answers it's a good idea to use ready to use Javascript toFixed() function to solve the problem. But most likely you'll encounter with some problems.

Imagine you are going to add up two float numbers like 0.2 and 0.7 here it is: 0.2 + 0.7 = 0.8999999999999999.

Your expected result was 0.9 it means you need a result with 1 digit precision in this case. So you should have used (0.2 + 0.7).tofixed(1) but you can't just give a certain parameter to toFixed() since it depends on the given number, for instance

0.22 + 0.7 = 0.9199999999999999

In this example you need 2 digits precision so it should be toFixed(2), so what should be the paramter to fit every given float number?

You might say let it be 10 in every situation then:

(0.2 + 0.7).toFixed(10) => Result will be "0.9000000000"

Damn! What are you going to do with those unwanted zeros after 9? It's the time to convert it to float to make it as you desire:

parseFloat((0.2 + 0.7).toFixed(10)) => Result will be 0.9

Now that you found the solution, it's better to offer it as a function like this:

function floatify(number){
           return parseFloat((number).toFixed(10));
        }
    

Let's try it yourself:

function floatify(number){
       return parseFloat((number).toFixed(10));
    }
 
function addUp(){
  var number1 = +$("#number1").val();
  var number2 = +$("#number2").val();
  var unexpectedResult = number1 + number2;
  var expectedResult = floatify(number1 + number2);
  $("#unexpectedResult").text(unexpectedResult);
  $("#expectedResult").text(expectedResult);
}
addUp();

input{
  width: 50px;
}
#expectedResult{
color: green;
}
#unexpectedResult{
color: red;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="number1" value="0.2" onclick="addUp()" onkeyup="addUp()"/> +
<input id="number2" value="0.7" onclick="addUp()" onkeyup="addUp()"/> =
<p>Expected Result: <span id="expectedResult"></span></p>
<p>Unexpected Result: <span id="unexpectedResult"></span></p>

You can use it this way:

var x = 0.2 + 0.7;
floatify(x);  => Result: 0.9

As W3SCHOOLS suggests there is another solution too, you can multiply and divide to solve the problem above:

var x = (0.2 * 10 + 0.1 * 10) / 10;       // x will be 0.3

Keep in mind that (0.2 + 0.1) * 10 / 10 won't work at all although it seems the same! I prefer the first solution since I can apply it as a function which converts the input float to accurate output float.

This concerns Java versions 7 and earlier.

To quote a good answer to the same question:

If you want it back as a string later, you can call getPath(). Indeed, if you really wanted to mimic Path.Combine, you could just write something like:

public static String combine (String path1, String path2) {
    File file1 = new File(path1);
    File file2 = new File(file1, path2);
    return file2.getPath();
}

A Java class can only extend one parent class. Multiple inheritance (extends) is not allowed. Interfaces are not classes, however, and a class can implement more than one interface.

The parent interfaces are declared in a comma-separated list, after the implements keyword.

In conclusion, yes, it is possible to do:

public class A implements C,D {...}

1. An Object file is the compiled file itself. There is no difference between the two.

2. An executable file is formed by linking the Object files.

3. Object file contains low level instructions which can be understood by the CPU. That is why it is also called machine code.

4. This low level machine code is the binary representation of the instructions which you can also write directly using assembly language and then process the assembly language code (represented in English) into machine language (represented in Hex) using an assembler.

Here's a typical high level flow for this process for code in High Level Language such as C

--> goes through pre-processor

--> to give optimized code, still in C

--> goes through compiler

--> to give assembly code

--> goes through an assembler

--> to give code in machine language which is stored in OBJECT FILES

--> goes through Linker

--> to get an executable file.

This flow can have some variations for example most compilers can directly generate the machine language code, without going through an assembler. Similarly, they can do the pre-processing for you. Still, it is nice to break up the constituents for a better understanding.

Feb 3rd 2020:

• Atlassian Bitbucket v5.8.3 local installation.
• I wanted to add a new line around an horizontal line. --- did produce the line, but I could not get new lines to work with suggestions above.
• note: I did not want to use the [space][space] suggestion, since my editor removes trailing spaces on save, and I like this feature on.

I ended up doing this:

TEXT...
<br><hr><br>
TEXT...

Resulting in:

TEXT...
<AN EMPTY LINE>
----------------- AN HORIZONTAL LINE ----------------
<AN EMPTY LINE>
TEXT...

function _arrayBufferToBase64(uarr) {
    var strings = [], chunksize = 0xffff;
    var len = uarr.length;

    for (var i = 0; i * chunksize < len; i++){
        strings.push(String.fromCharCode.apply(null, uarr.subarray(i * chunksize, (i + 1) * chunksize)));
    }

    return strings.join("");
}

This is better, if you use JSZip for unpack archive from string

You can use the DataGridViewCell.Value Property to retrieve the value stored in a particular cell.

So to retrieve the value of the 'first' selected Cell and display in a MessageBox, you can:

MessageBox.Show(dataGridView1.SelectedCells[0].Value.ToString());

The above probably isn't exactly what you need to do. If you provide more details we can provide better help.

In addition to others' proposals, there is another option to handle that issue.

If your application should behave the same in case of lack of "href" attribute, as in case of it being empty, just replace this:

var theHref = $(obj.mainImg_select).attr('href');

with this:

var theHref = $(obj.mainImg_select).attr('href') || '';

which will treat empty string ('') as the default, if the attribute has not been found.

But it really depends, on how you want to handle undefined "href" attribute. This answer assumes you will want to handle it as if it was empty string.

Suppose we have 14 records of name column in table

in group by

select name,count(*) as totalcount from person where name='Please fill out' group BY name;

it will give count in single row i.e 14

but in partition by

select row_number() over (partition by name) as total from person where name = 'Please fill out';

it will 14 rows of increase in count

OK, so I found the answer from http://binglongx.wordpress.com/2009/01/26/visual-c-does-not-generate-lib-file-for-a-dll-project/ says that this problem was caused by not exporting any symbols and further instructs on how to export symbols to create the lib file. To do so, add the following code to your .h file for your DLL.

#ifdef BARNABY_EXPORTS
#define BARNABY_API __declspec(dllexport)
#else
#define BARNABY_API __declspec(dllimport)
#endif

Where BARNABY_EXPORTS and BARNABY_API are unique definitions for your project. Then, each function you export you simply precede by:

BARNABY_API int add(){
}

This problem could have been prevented either by clicking the Export Symbols box on the new project DLL Wizard or by voting yes for lobotomies for computer programmers.

    INSERT INTO Persons_Table (person_id, person_name,person_email)
          SELECT person_id, customer_name, customer_email
          FROM customer_table
          WHERE "insert your where clause here";
    DELETE FROM customer_table
          WHERE "repeat your where clause here";

The usual way is to use uuencode for the attachments and echo for the body:

(uuencode output.txt output.txt; echo "Body of text") | mailx -s 'Subject' [email protected]

For Solaris and AIX, you may need to put the echo statement first:

(echo "Body of text"; uuencode output.txt output.txt) | mailx -s 'Subject' [email protected]

   private List<Country> countries; 

   //getter - setter
}

RestTemplate restTemplate = new RestTemplate();

let unixtime = Date.parse(datetime)/1000;
console.log('unixtime:',unixtime);

to prove it:

let milliseconds = unixtime * 1000;

Assuming you're happy with truncating towards zero, just cast:

double d = 1234.56;
long x = (long) d; // x = 1234

This will be faster than going via the wrapper classes - and more importantly, it's more readable. Now, if you need rounding other than "always towards zero" you'll need slightly more complicated code.

Example. To find number of vowels within the string

var word='Web Development Tutorial';
var vowels='[aeiou]'; 
var re = new RegExp(vowels, 'gi');
var arr = word.match(re);
document.write(arr.length);

In my case, it seems ng is not registered into my environment path. I have been using npm run command to run the ng commands. Be aware in order to pass arguments you need an extra -- as per the npm run specification.

Or:

npm run ng g c components/scheduling **--** --skip-import

From ggplot2 2.0.0 you can use the margin = argument of element_text() to change the distance between the axis title and the numbers. Set the values of the margin on top, right, bottom, and left side of the element.

ggplot(mpg, aes(cty, hwy)) + geom_point()+
  theme(axis.title.y = element_text(margin = margin(t = 0, r = 20, b = 0, l = 0)))

margin can also be used for other element_text elements (see ?theme), such as axis.text.x, axis.text.y and title.

addition

in order to set the margin for axis titles when the axis has a different position (e.g., with scale_x_...(position = "top"), you'll need a different theme setting - e.g. axis.title.x.top. See https://github.com/tidyverse/ggplot2/issues/4343.

I believe, the 500ms run in the background, while the rest of the code continues to execute and empties the list.

Then after 500ms nothing happens, as no function-call is implemented in the after-callup (same as frame.after(500, function=None))

Extremely Lightweight Modal popup plugin. POPELT - http://welbour.com/labs/popelt/

It is lightweight, supports nested popups, object oriented, supports dynamic buttons, responsive, and lot more. Next update will include Popup Ajax form submissions etc.

Feel free to use and tweet feedback.

Note: The original question was answered already, but I would just like to expand on it with some extras that are relevant to the topic.

Your AIX installation would first be put into volume groups. This is done upon installation.

It will first create rootvg (as in root volume group). This is kinda like your actual hard drive mapped.

This would be equivalent to Disc Management in Windows. AIX wont use up all of that space for its file systems like we tend to do it in consumer Windows machines. Instead there will be a good bit of unallocated space.

To check how much space your rootvg would have you use the following command.

lsvg rootvg

That would stand for list volume group rootvg. This will give you information like the size of physical partitions (PP), Total PPs assigned to the volume group, Free PPs in the volume group, etc. Regardless, the output should be fairly comprehensive.

Next thing you may be interested in, is the file systems on the volume group. Each file system would have certain amount of space given within the volume group it belongs to.

To check what file systems you got on your volume group you use the following command.

lsvgfs rootvg

As in list volume group file systems for rootvg.

You can check how much space each file system has using the following command.

df

I personally like to refine it with flags like -m and -g (in megabytes and gigabytes respectively)

If you have free space available in your volume group, you can assign it to your file systems using the following command.

chfs -a size=+1G /home

As in change file system attribute size by adding 1 G where file system is /home. use man chfs for more instructions. This is a powerful tool. This example is for adjusting size, however you can do more with this command than that.

I had same problem and finally found my mistake :) I used this command for compiling and it worked correctly:

javac -cp "/home/omidmohebbi/AAAATest/jars/core-1.7.jar:/home/omidmohebbi/AAAATest/jars/javase-1.7.jar:/home/omidmohebbi/AAAATest/jars/qrgen-1.2.jar" qrcode.java

But this command did not work for me (I could not find or load the main class, qrcode):

java -cp "/home/omidmohebbi/AAAATest/jars/core-1.7.jar:/home/omidmohebbi/AAAATest/jars/javase-1.7.jar:/home/omidmohebbi/AAAATest/jars/qrgen-1.2.jar" qrcode

Finally I just added the ':' character at end of the classpath and the problem was solved:

java -cp "/home/omidmohebbi/AAAATest/jars/core-1.7.jar:/home/omidmohebbi/AAAATest/jars/javase-1.7.jar:/home/omidmohebbi/AAAATest/jars/qrgen-1.2.jar:" qrcode

you can use hidden property of element:

document.getElementById("test").hidden=true;
document.getElementById("test").hidden=false

The suitable way to analyze an algorithm is by determining its worst case scenarios. Euclidean GCD's worst case occurs when Fibonacci Pairs are involved. void EGCD(fib[i], fib[i - 1]), where i > 0.

For instance, let's opt for the case where the dividend is 55, and the divisor is 34 (recall that we are still dealing with fibonacci numbers).

As you may notice, this operation costed 8 iterations (or recursive calls).

Let's try larger Fibonacci numbers, namely 121393 and 75025. We can notice here as well that it took 24 iterations (or recursive calls).

You can also notice that each iterations yields a Fibonacci number. That's why we have so many operations. We can't obtain similar results only with Fibonacci numbers indeed.

Hence, the time complexity is going to be represented by small Oh (upper bound), this time. The lower bound is intuitively Omega(1): case of 500 divided by 2, for instance.

Let's solve the recurrence relation:

We may say then that Euclidean GCD can make log(xy) operation at most.

You can use the reset() function, it will return the first array member.

You can use the String split method to get the single numbers as an array of strings. Then convert them to numbers with the unary plus operator, the Number function or parseInt, and add them to your array:

var arr = [1,2,3],
    strVale = "130,235,342,124 ";
var strings = strVale.split(",");
for (var i=0; i<strVale.length; i++)
    arr.push( + strings[i] );

Or, in one step, using Array map to convert them and applying them to one single push:

arr.push.apply(arr, strVale.split(",").map(Number));

DATE_ADD works correctly. 1 January plus 6 months is 1 July, just like 1 January plus 1 month is 1 of February.

Between operation is inclusive. So, you are getting everything up to, and including, 1 July. (see also MySQL "between" clause not inclusive?)

What you need to do is subtract 1 day or use < operator instead of between.

In situations I usually come across, I rarely use IList directly.

Usually I just use it as an argument to a method

void ProcessArrayData(IList almostAnyTypeOfArray)
{
    // Do some stuff with the IList array
}

This will allow me to do generic processing on almost any array in the .NET framework, unless it uses IEnumerable and not IList, which happens sometimes.

It really comes down to the kind of functionality you need. I'd suggest using the List class in most cases. IList is best for when you need to make a custom array that could have some very specific rules that you'd like to encapsulate within a collection so you don't repeat yourself, but still want .NET to recognize it as a list.

import numpy as np
# any two python array as two points
a = [0, 0]
b = [3, 4]

You first change list to numpy array and do like this: print(np.linalg.norm(np.array(a) - np.array(b))). Second method directly from python list as: print(np.linalg.norm(np.subtract(a,b)))

no need for the padding or the corners.

here's a sample:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" >
    <gradient android:startColor="#FFFF0000" android:endColor="#80FF00FF"
        android:angle="270"/>
</shape>

Add a default constraint with the GETDATE() function as value.

ALTER TABLE myTable 
  ADD CONSTRAINT CONSTRAINT_NAME
    DEFAULT GETDATE() FOR myColumn

public static void main(String[] args) {
          Scanner input =new Scanner(System.in);
          System.out.print("enter how many:");
         int num =input.nextInt();
    int[] arr= new int [num];
    for(int b=0;b<arr.length;b++){
   System.out.print("enter no." + (b+1) +"=");
   arr[b]=input.nextInt();

    for (int i=0; i<arr.length;i++) {
        for (int k=i;k<arr.length;k++) {

        if(arr[i] > arr[k]) {

        int temp=arr[k];
        arr[k]=arr[i];
        arr[i]=temp;

    for (int i : arr){

/usr/sbin/host `hostname`

 /usr/sbin/ifconfig -a inet | awk '/inet/ {print $2}'

You want the argument unpacking operator *.

For anyone using Windows container like me, know that you CANNOT bind or mount single files using windows container.

The following examples will fail when using Windows-based containers, as the destination of a volume or bind mount inside the container must be one of: a non-existing or empty directory; or a drive other than C:. Further, the source of a bind mount must be a local directory, not a file.

net use z: \\remotemachine\share

docker run -v z:\foo:c:\dest ...

docker run -v \\uncpath\to\directory:c:\dest ...

docker run -v c:\foo\somefile.txt:c:\dest ...

docker run -v c:\foo:c: ...

docker run -v c:\foo:c:\existing-directory-with-contents ...

You get an extension ID when you upload your extension to Google Web Store. Ie. Adblock has URL https://chrome.google.com/webstore/detail/cfhdojbkjhnklbpkdaibdccddilifddb and the last part of this URL is its extension ID cfhdojbkjhnklbpkdaibdccddilifddb.

If you wish to read installed extension IDs from your extension, check out the managment module. chrome.management.getAll allows to fetch information about all installed extensions.

It can be changed in the $CATALINA_BASE/conf/server.xml in the <Host />. See the Tomcat documentation, specifically the section in regards to the Host container:

Add a method to Card that creates a full deck of cards, with one card of each combination of rank and suit.

So without modifying or enhancing the given code other than adding the method (and without using stuff that hasn't been taught yet), I came up with this solution:

struct Card {
    var rank: Rank
    var suit: Suit

    func simpleDescription() -> String {
        return "The \(rank.simpleDescription()) of \(suit.simpleDescription())"
    }

    func createDeck() -> [Card] {
        var deck: [Card] = []
        for rank in Rank.Ace.rawValue...Rank.King.rawValue {
            for suit in Suit.Spades.rawValue...Suit.Clubs.rawValue {
                let card = Card(rank: Rank(rawValue: rank)!, suit: Suit(rawValue: suit)!)
                //println(card.simpleDescription())
                deck += [card]
            }
        }
        return deck
    }
}
let threeOfSpades = Card(rank: .Three, suit: .Spades)
let threeOfSpadesDescription = threeOfSpades.simpleDescription()
let deck = threeOfSpades.createDeck()

Prior to version 1.14, wget timeout arguments were not adhered to if downloading over https due to a bug.

The local names for a function are decided when the function is defined:

>>> x = 1
>>> def inc():
...     x += 5
...     
>>> inc.__code__.co_varnames
('x',)

In this case, x exists in the local namespace. Execution of x += 5 requires a pre-existing value for x (for integers, it's like x = x + 5), and this fails at function call time because the local name is unbound - which is precisely why the exception UnboundLocalError is named as such.

Compare the other version, where x is not a local variable, so it can be resolved at the global scope instead:

>>> def incg():
...    print(x)
...    
>>> incg.__code__.co_varnames
()

The way to keep SELECT dbo.fCalculateEstimateDate(647) call working is:

ALTER function [dbo].[fCalculateEstimateDate] (@vWorkOrderID numeric)
Returns varchar(100)  AS
   Declare @Result varchar(100)
   SELECT @Result = [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID,DEFAULT)
   Return @Result

End

CREATE function [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID numeric,@ToDate DateTime=null)
Returns varchar(100)  AS
Begin
  <Function Body>
End

IoC concept was initially heard during the procedural programming era. Therefore from a historical context IoC talked about inversion of the ownership of control-flow i.e. who owns the responsibility to invoke the functions in the desired order - whether it's the functions themselves or should you invert it to some external entity.

However once the OOP emerged, people began to talk about IoC in OOP context where applications are concerned with object creation and their relationships as well, apart from the control-flow. Such applications wanted to invert the ownership of object-creation (rather than control-flow) and required a container which is responsible for object creation, object life-cycle & injecting dependencies of the application objects thereby eliminating application objects from creating other concrete object.

In that sense DI is not the same as IoC, since it's not about control-flow, however it's a kind of Io*, i.e. Inversion of ownership of object-creation.

What is wrong in my way of explainning DI and IoC?

For pre API 8 i solved the problem using a boolean flag, a dismiss listener and calling dialog.show again if in case the content of the editText wasn´t correct. Like this:

case ADD_CLIENT:
        LayoutInflater factoryClient = LayoutInflater.from(this);
        final View EntryViewClient = factoryClient.inflate(
                R.layout.alert_dialog_add_client, null);

                .findViewById(R.id.client_edit);

        AlertDialog.Builder builderClient = new AlertDialog.Builder(this);
        builderClient

                                            Toast.LENGTH_SHORT).show();
                                    add_client_error = true;
                                } else {
                                    //Here save the info and set the error flag to false
                                    add_client_error = false;
                                }
                            }
                        })
                .setNegativeButton("Cancel",
                        new DialogInterface.OnClickListener() {

                            }
                        });
        final AlertDialog alertClient = builderClient.create();
        alertClient.show();

        alertClient
                .setOnDismissListener(new DialogInterface.OnDismissListener() {

                    @Override
                    public void onDismiss(DialogInterface dialog) {
                        //If the error flag was set to true then show the dialog again
                        if (add_client_error == true) {
                            alertClient.show();
                        } else {
                            return;

I have a folder /fields full of files with a single class each, ex:

fields/Text.js -> Test class
fields/Checkbox.js -> Checkbox class

Drop this in fields/index.js to export each class:

var collectExports, fs, path,
  __hasProp = {}.hasOwnProperty;

fs = require('fs');    
path = require('path');

collectExports = function(file) {
  var func, include, _results;

  if (path.extname(file) === '.js' && file !== 'index.js') {
    include = require('./' + file);
    _results = [];
    for (func in include) {
      if (!__hasProp.call(include, func)) continue;
      _results.push(exports[func] = include[func]);
    }
    return _results;
  }
};

fs.readdirSync('./fields/').forEach(collectExports);

This makes the modules act more like they would in Python:

var text = new Fields.Text()
var checkbox = new Fields.Checkbox()

From what I understand they are independent of one another. By keeping the session timeout less than or equal to the authentication timeout, you can make sure any user-specific session variables are not persisted after the authentication has timed out (if that is your concern, which I think is the normal one when asking this question). Of course, you'll have to manually handle the disposal of session variables upon log-out.

Here is a decent response that may answer your question or at least point you in the right direction:

• Forms Authentication Timeout vs Session Timeout

I've used min-height: 100vh; with great success on some of my projects. See example.

You have to wrap your Javascript-Code with $(document).ready(function(){});Look this JSfiddle.

JS Code:

$(document).ready(function() {

        alert("Hello!");
        $(".hide_div").hide();    
    });
});

Check against any long running queries in your database.

Increasing your pool size will only make your webapp live a little longer (and probably get a lot slower)

You can use sql server profiler and filter on duration / reads to see which querys need optimization.

I also see you're probably keeping a global connection?

blnMainConnectionIsCreatedLocal

Let .net do the pooling for you and open / close your connection with a using statement.

Suggestions:

1. Always open and close a connection like this, so .net can manage your connections and you won't run out of connections:

       using (SqlConnection conn = new SqlConnection(connectionString))
       {
        conn.Open();
        // do some stuff
       } //conn disposed
   

2. As I mentioned, check your query with sql server profiler and see if you can optimize it. Having a slow query with many requests in a web app can give these timeouts too.

I think the xpath query you want goes something like this:

/xml/box[@stepId="$stepId"]/components/component[@id="$componentId"]/variables/variable[@nom="Enabled" and @valeur="Yes"]

This should get you the variables that are named "Enabled" with a value of "Yes" for the specified $stepId and $componentId. This is assuming that your xml starts with an tag like you show, and not

If the SQL Server 2005 XPath stuff is pretty straightforward (I've never used it), then the above query should work. Otherwise, someone else may have to help you with that.

You can create an interface, pass it to AsyncTask (in constructor), and then call method in onPostExecute()

For example:

Your interface:

public interface OnTaskCompleted{
    void onTaskCompleted();
}

Your Activity:

public class YourActivity implements OnTaskCompleted{
    // your Activity
}

And your AsyncTask:

public class YourTask extends AsyncTask<Object,Object,Object>{ //change Object to required type
    private OnTaskCompleted listener;

    public YourTask(OnTaskCompleted listener){
        this.listener=listener;
    }

    // required methods

    protected void onPostExecute(Object o){
        // your stuff
        listener.onTaskCompleted();
    }
}

EDIT

Since this answer got quite popular, I want to add some things.

If you're a new to Android development, AsyncTask is a fast way to make things work without blocking UI thread. It does solves some problems indeed, there is nothing wrong with how the class works itself. However, it brings some implications, such as:

• Possibility of memory leaks. If you keep reference to your Activity, it will stay in memory even after user left the screen (or rotated the device).
• AsyncTask is not delivering result to Activity if Activity was already destroyed. You have to add extra code to manage all this stuff or do you operations twice.
• Convoluted code which does everything in Activity

When you feel that you matured enough to move on with Android, take a look at this article which, I think, is a better way to go for developing your Android apps with asynchronous operations.

            });
          }, 5000);

Ajax call to activeUser.php

if(isset($_POST['action'])){
    if(isset($_POST['userid'])){
        $stamp = time();
        $activeid = $_POST['userid'];
        $ip = $_POST['ipaddress'];

        $query = "SELECT stamp FROM activeusers WHERE activeid = '".$activeid."' LIMIT 1";
        $results = RUNSIMPLEDB($query);

        if($results->num_rows > 0){
            $query = "UPDATE activeusers SET stamp = '$stamp' WHERE activeid = '".$activeid."' AND ip = '$ip' LIMIT 1";
            RUNSIMPLEDB($query);
        }else{
            $query = "INSERT INTO activeusers (activeid,stamp,ip)
                    VALUES ('".$activeid."','$stamp','$ip')";
            RUNSIMPLEDB($query);
        }
    }
}

Database:

CREATE TABLE `activeusers` (
  `id` int(11) NOT NULL,
  `activeid` varchar(20) NOT NULL,
  `stamp` int(11) NOT NULL,
  `ip` text
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

Basically every 5 seconds the js will post to a php file that will track the user and the users ip address. Active users are simply a database record that have an update to the database time stamp within 5 seconds. Old users stop updating to the database. The ip address is used just to ensure that a user is unique so 2 people on the site at the same time don't register as 1 user.

Probably not the most efficient solution but it does the job.

I had the same problem, resolved it by adding

<filtering>true</filtering> 

in pom.xml :

before (didn't work):

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>               
        </resource>
    </resources>
</build>

after(it worked):

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
        </resource>
    </resources>
</build>

After that you just run mvn clean install and deploy application.

I'd aditionally recommend putting the output of var_dump() or printr into a pre tag when outputting to a browser.

print "<pre>";
print_r($dataset);
print "</pre>";

Will give a more readable result.

i'd like to start by understanding the problem

Browsers make HTTP requests to servers. The server then makes an HTTP response.

Both requests and responses consist of a bunch of headers and a (sometimes optional) body with some content in it.

If there is a body, then one of the headers is the Content-Type which describes what the body is (is it an HTML document? An image? The contents of a form submission? etc).

When you ask for your stylesheet, your server is telling the browser that it is an HTML document (Content-Type: text/html) instead of a stylesheet (Content-Type: text/css).

I've already checked my myme.type and text/css is already on css.

Then something else about your server is making that stylesheet come with the wrong content type.

Use the Net tab of your browser's developer tools to examine the request and the response.

SELECT COUNT(1)
FROM FB
WHERE
    Dte BETWEEN CAST(YEAR(GETDATE()) AS VARCHAR(4)) + '-' + CAST(MONTH(DATEADD(month, -1, GETDATE())) AS VARCHAR(2)) + '-20 00:00:00'
        AND CAST(YEAR(GETDATE()) AS VARCHAR(4)) + '-' + CAST(MONTH(GETDATE()) AS VARCHAR(2)) + '-20 00:00:00'

I recommend unlist, which keeps the names.

unlist(df[1,])
  a   b   c 
1.0 2.0 2.6 

is.vector(unlist(df[1,]))
[1] TRUE

If you don't want a named vector:

unname(unlist(df[1,]))
[1] 1.0 2.0 2.6

private void btnchangerate_Click(object sender, EventArgs e)
    {
        this.Hide();  //current form will hide
        Form1 fm = new Form1(); //another form will open
        fm.Show();


    }

on click btn current form will hide and new form will open

I just ran into this issue and checked all of the above answers to make sure I wasn't missing anything obvious. Well, I had a semi-obvious issue. My casing of my classname in code and the classname I used in the configuration file didn't match.

For example: if the class name is CalculatorService and the configuration file refers to Calculatorservice ... you will get this error.

Solution given by Chris Barr here

function isTouchDevice(){
    try{
        document.createEvent("TouchEvent");
        return true;
    }catch(e){
        return false;
    }
}

function touchScroll(id){
    if(isTouchDevice()){ //if touch events exist...
        var el=document.getElementById(id);
        var scrollStartPos=0;

        document.getElementById(id).addEventListener("touchstart", function(event) {
            scrollStartPos=this.scrollTop+event.touches[0].pageY;
            event.preventDefault();
        },false);

        document.getElementById(id).addEventListener("touchmove", function(event) {
            this.scrollTop=scrollStartPos-event.touches[0].pageY;
            event.preventDefault();
        },false);
    }
}

Works fine for me. Remove event.preventDefault if you need to use some clicks...

Your linker (ld) obviously doesn't like the order in which make arranges the GCC arguments so you'll have to change your Makefile a bit:

CC=gcc
CFLAGS=-Wall
LDFLAGS=-lm

.PHONY: all
all: client

.PHONY: clean
clean:
    $(RM) *~ *.o client

OBJECTS=client.o
client: $(OBJECTS)
    $(CC) $(CFLAGS) $(OBJECTS) -o client $(LDFLAGS)

In the line defining the client target change the order of $(LDFLAGS) as needed.

The URLs are passed in the request: request.getRequestURL().

If you mean other sites that are linking to you? You want to capture the HTTP Referrer, which you can do by calling:

request.getHeader("referer");

Is $target.remove(); what you're looking for?

https://api.jquery.com/remove/

# this works:
rm foo
# versus this, which doesn't:
rm foo/

Basically, you need to tell it to delete a file, not delete a directory. I believe the difference between rm and rmdir exists because of differences in the way the C library treats each.

At any rate, the first should work, while the second should complain about foo being a directory.

If it doesn't work as above, then check your permissions. You need write permission to the containing directory to remove files.

Here are some more tests

True if string is not empty:

[ -n "$var" ]
[[ -n $var ]]
test -n "$var"
[ "$var" ]
[[ $var ]]
(( ${#var} ))
let ${#var}
test "$var"

True if string is empty:

[ -z "$var" ]
[[ -z $var ]]
test -z "$var"
! [ "$var" ]
! [[ $var ]]
! (( ${#var} ))
! let ${#var}
! test "$var"

I needed to find a way to do this too, using numbers from different places and not in a collection. I was sure there was a method to do this in c#...though by the looks of it I'm muddling my languages...

Anyway, I ended up writing a couple of generic methods to do it...

    static T Max<T>(params T[] numberItems)
    {
        return numberItems.Max();
    }

    static T Min<T>(params T[] numberItems)
    {
        return numberItems.Min();
    }

...call them this way...

    int intTest = Max(1, 2, 3, 4);
    float floatTest = Min(0f, 255.3f, 12f, -1.2f);

This function found here, works fine for me

function jsonRemoveUnicodeSequences($struct) {
   return preg_replace("/\\\\u([a-f0-9]{4})/e", "iconv('UCS-4LE','UTF-8',pack('V', hexdec('U$1')))", json_encode($struct));
}

Check out Datejs. Their built in formatters can do this: http://code.google.com/p/datejs/wiki/APIDocumentation#toString

It's a really handy library, especially if you are planning on doing other things with date objects.

For anyone who wants to find the build directory from a script but does not want to change it, run the following to get a list of all the build settings that point to a folder in DerivedData:

xcodebuild -showBuildSettings | grep DerivedData

If you run custom targets and schemes, please put them there as well:

xcodebuild -workspace "Foo.xcworkspace" -scheme "Bar" -sdk iphonesimulator -configuration Debug -showBuildSettings | grep DerivedData

Look at the output to locate the setting output that you want and then:

xcodebuild -showBuildSettings | grep SYMROOT | cut -d "=" -f 2 - | sed 's/^ *//'

The last part cuts the string at the equal sign and then trims the whitespace at the beginning.

If you can assume that artist IDs increment over time, then the MIN(artist_id) will be the earliest.

So try something like this (untested...)

SELECT *
  FROM feeds f
  LEFT JOIN artists a ON a.artist_id = (
    SELECT
      MIN(fa.artist_id) a_id
    FROM feeds_artists fa 
    WHERE fa.feed_id = f.feed_id
  ) a

I had this issue when I was using homebrew. Here is the solution from Issue #26900

python -m pip install --upgrade --force pip

Set style= "display:none;". By setting visible=false, it will not render button in the browser. Thus,client side script wont execute.

<asp:Button ID="savebtn" runat="server" OnClick="savebtn_Click" style="display:none" />

html markup should be

<button id="btnsave" onclick="fncsave()">Save</button>

Change javascript to

<script type="text/javascript">
     function fncsave()
     {
        document.getElementById('<%= savebtn.ClientID %>').click();
     }
</script>

You can use the following code. Here I am uploading the image to firebase storage and then I am storing the image download url to firebase database.

//getting the storage reference
            StorageReference sRef = storageReference.child(Constants.STORAGE_PATH_UPLOADS + System.currentTimeMillis() + "." + getFileExtension(filePath));

            //adding the file to reference 
            sRef.putFile(filePath)
                    .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                        @Override
                        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                            //dismissing the progress dialog
                            progressDialog.dismiss();

                            //displaying success toast 
                            Toast.makeText(getApplicationContext(), "File Uploaded ", Toast.LENGTH_LONG).show();

                            //creating the upload object to store uploaded image details 
                            Upload upload = new Upload(editTextName.getText().toString().trim(), taskSnapshot.getDownloadUrl().toString());

                            //adding an upload to firebase database 
                            String uploadId = mDatabase.push().getKey();
                            mDatabase.child(uploadId).setValue(upload);
                        }
                    })
                    .addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception exception) {
                            progressDialog.dismiss();
                            Toast.makeText(getApplicationContext(), exception.getMessage(), Toast.LENGTH_LONG).show();
                        }
                    })
                    .addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
                        @Override
                        public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
                            //displaying the upload progress 
                            double progress = (100.0 * taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount();
                            progressDialog.setMessage("Uploaded " + ((int) progress) + "%...");
                        }
                    });

Now to fetch all the images stored in firebase database you can use

//adding an event listener to fetch values
        mDatabase.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(DataSnapshot snapshot) {
                //dismissing the progress dialog 
                progressDialog.dismiss();

                //iterating through all the values in database
                for (DataSnapshot postSnapshot : snapshot.getChildren()) {
                    Upload upload = postSnapshot.getValue(Upload.class);
                    uploads.add(upload);
                }
                //creating adapter
                adapter = new MyAdapter(getApplicationContext(), uploads);

                //adding adapter to recyclerview
                recyclerView.setAdapter(adapter);
            }

            @Override
            public void onCancelled(DatabaseError databaseError) {
                progressDialog.dismiss();
            }
        });

Fore more details you can see my post Firebase Storage Example.

You can use the curl_error() function to detect if there was some error. For example:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $your_url);
curl_setopt($ch, CURLOPT_FAILONERROR, true); // Required for HTTP error codes to be reported via our call to curl_error($ch)
//...
curl_exec($ch);
if (curl_errno($ch)) {
    $error_msg = curl_error($ch);
}
curl_close($ch);

if (isset($error_msg)) {
    // TODO - Handle cURL error accordingly
}

See the description of libcurl error codes here

See the description of PHP curl_errno() function here

The server sends the following in its response header to set a cookie field.

Set-Cookie:name=value

If there is a cookie set, then the browser sends the following in its request header.

Cookie:name=value

See the HTTP Cookie article at Wikipedia for more information.

When I was learning venv I created a script to remind me how to activate it.

#!/bin/sh
# init_venv.sh
if [ -d "./bin" ];then
  echo "[info] Ctrl+d to deactivate"
  bash -c ". bin/activate; exec /usr/bin/env bash --rcfile <(echo 'PS1=\"(venv)\${PS1}\"') -i"
fi

This has the advantage that it changes the prompt.

Numbers in JS use a . (full stop / period) character to indicate the decimal point not a , (comma).

This works for me:

for each series, use a random rgb colour generator

c = color[np.random.random_sample(), np.random.random_sample(), np.random.random_sample()]

as.character() would be the general way rather than use paste() for its side effect

> v <- 20081101
> date <- as.Date(as.character(v), format = "%Y%m%d")
> date
[1] "2008-11-01"

(I presume this is a simple example and something like this:

v <- "20081101"

isn't possible?)

The C5 Generic Collections Library classes all support the AddRange method. C5 has a much more robust interface that actually exposes all of the features of its underlying implementations and is interface-compatible with the System.Collections.Generic ICollection and IList interfaces, meaning that C5's collections can be easily substituted as the underlying implementation.

Hibernate, because it's basically the defacto standard in Java and was one of the driving forces in the creation of the JPA. It's got excellent support in Spring, and almost every Java framework supports it. Finally, GORM is a really cool wrapper around it doing dynamic finders and so on using Groovy.

It's even been ported to .NET (NHibernate) so you can use it there too.

If you are searching literally the way to return a JSON list in flask and you are completly sure that your variable is a list then the easy way is (where bin is a list of 1's and 0's):

   return jsonify({'ans':bin}), 201

Finally, in your client you will obtain something like

{ "ans": [ 0.0, 0.0, 1.0, 1.0, 0.0 ] }

Adding placeholder attributes from code-behind:

txtFilterTerm.Attributes.Add("placeholder", "Filter" + Filter.Name);

Or

txtFilterTerm.Attributes["placeholder"] = "Filter" + Filter.Name;

Adding placeholder attributes from aspx Page

<asp:TextBox type="text" runat="server" id="txtFilterTerm" placeholder="Filter" />

Or

<input type="text" id="txtFilterTerm" placeholder="Filter"/>

A Runnable is basically a type of class (Runnable is an Interface) that can be put into a thread, describing what the thread is supposed to do.

The Runnable Interface requires of the class to implement the method run() like so:

public class MyRunnableTask implements Runnable {
     public void run() {
         // do stuff here
     }
}

And then use it like this:

Thread t = new Thread(new MyRunnableTask());
t.start();

If you did not have the Runnable interface, the Thread class, which is responsible to execute your stuff in the other thread, would not have the promise to find a run() method in your class, so you could get errors. That is why you need to implement the interface.

Advanced: Anonymous Type

Note that you do not need to define a class as usual, you can do all of that inline:

Thread t = new Thread(new Runnable() {
    public void run() {
        // stuff here
    }
});
t.start();

This is similar to the above, only you don't create another named class.

How about:

<table>
  <tr ng-repeat="(key, value) in data">
    <td> {{key}} </td> <td> {{ value }} </td>
  </tr>
</table>

This method is listed in the docs: https://docs.angularjs.org/api/ng/directive/ngRepeat

Semaphore can also be used as a ... semaphore. For example if you have multiple process enqueuing data to a queue, and only one task consuming data from the queue. If you don't want your consuming task to constantly poll the queue for available data, you can use semaphore.

Here the semaphore is not used as an exclusion mechanism, but as a signaling mechanism. The consuming task is waiting on the semaphore The producing task are posting on the semaphore.

This way the consuming task is running when and only when there is data to be dequeued

There is another way that I found works, you have to build a class that derives from your Product class and use that. For instance:

public class PseudoProduct : Product { }

public IQueryable<Product> GetProducts(int categoryID)
{
    return from p in db.Products
           where p.CategoryID== categoryID
           select new PseudoProduct() { Name = p.Name};
}

Not sure if this is "allowed", but it works.

I wanted to cover a simple way of doing this with the front end too:

Controller:

public ActionResult Index(int page = 0)
{
    const int PageSize = 3; // you can always do something more elegant to set this

    var count = this.dataSource.Count();

    var data = this.dataSource.Skip(page * PageSize).Take(PageSize).ToList();

    this.ViewBag.MaxPage = (count / PageSize) - (count % PageSize == 0 ? 1 : 0);

    this.ViewBag.Page = page;

    return this.View(data);
}

View:

@* rest of file with view *@

@if (ViewBag.Page > 0)
{
    <a href="@Url.Action("Index", new { page = ViewBag.Page - 1 })" 
       class="btn btn-default">
        &laquo; Prev
    </a>
}
@if (ViewBag.Page < ViewBag.MaxPage)
{
    <a href="@Url.Action("Index", new { page = ViewBag.Page + 1 })" 
       class="btn btn-default">
        Next &raquo;
    </a>
}

Use this to force IE to hide that annoying browser compatibility button in the address bar:

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

Try this way

final CharSequence[] items = { "Take Photo", "Choose from Library",
            "Cancel" };

    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
    builder.setTitle("Add Photo!");
    builder.setItems(items, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int item) {
            if (items[item].equals("Take Photo")) {
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                File f = new File(android.os.Environment
                        .getExternalStorageDirectory(), "temp.jpg");
                intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
                startActivityForResult(intent, REQUEST_CAMERA);
            } else if (items[item].equals("Choose from Library")) {
                Intent intent = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                intent.setType("image/*");
                startActivityForResult(
                        Intent.createChooser(intent, "Select File"),
                        SELECT_FILE);
            } else if (items[item].equals("Cancel")) {
                dialog.dismiss();
            }
        }
    });
    builder.show();

Then create onactivityresult method and do something like this

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        if (requestCode == REQUEST_CAMERA) {
            File f = new File(Environment.getExternalStorageDirectory()
                    .toString());
            for (File temp : f.listFiles()) {
                if (temp.getName().equals("temp.jpg")) {
                    f = temp;
                    break;
                }
            }
            try {
                Bitmap bm;
                BitmapFactory.Options btmapOptions = new BitmapFactory.Options();

                bm = BitmapFactory.decodeFile(f.getAbsolutePath(),
                        btmapOptions);

                // bm = Bitmap.createScaledBitmap(bm, 70, 70, true);
                ivImage.setImageBitmap(bm);

                String path = android.os.Environment
                        .getExternalStorageDirectory()
                        + File.separator
                        + "Phoenix" + File.separator + "default";
                f.delete();
                OutputStream fOut = null;
                File file = new File(path, String.valueOf(System
                        .currentTimeMillis()) + ".jpg");
                try {
                    fOut = new FileOutputStream(file);
                    bm.compress(Bitmap.CompressFormat.JPEG, 85, fOut);

Try format function:

> xx = 100000000000
> xx
[1] 1e+11
> format(xx, scientific=F)
[1] "100000000000"

Please try this one

NSError *error;
NSDictionary *responseJson = [NSJSONSerialization JSONObjectWithData:webData
                                options:NSJSONReadingMutableContainers
                                error:&error];

A quick recap of the 2 approaches with speed comparison being the important part.

http://geekswithblogs.net/BlackRabbitCoder/archive/2013/07/25/c.net-little-wonders-getting-caller-information.aspx

Determining the caller at compile-time

static void Log(object message, 
[CallerMemberName] string memberName = "",
[CallerFilePath] string fileName = "",
[CallerLineNumber] int lineNumber = 0)
{
    // we'll just use a simple Console write for now    
    Console.WriteLine("{0}({1}):{2} - {3}", fileName, lineNumber, memberName, message);
}

Determining the caller using the stack

static void Log(object message)
{
    // frame 1, true for source info
    StackFrame frame = new StackFrame(1, true);
    var method = frame.GetMethod();
    var fileName = frame.GetFileName();
    var lineNumber = frame.GetFileLineNumber();

    // we'll just use a simple Console write for now    
    Console.WriteLine("{0}({1}):{2} - {3}", fileName, lineNumber, method.Name, message);
}

Comparison of the 2 approaches

Time for 1,000,000 iterations with Attributes: 196 ms
Time for 1,000,000 iterations with StackTrace: 5096 ms

So you see, using the attributes is much, much faster! Nearly 25x faster in fact.

std::vector<CustomClass *> whatever(20000);

or:

std::vector<CustomClass *> whatever;
whatever.reserve(20000);

The former sets the actual size of the array -- i.e., makes it a vector of 20000 pointers. The latter leaves the vector empty, but reserves space for 20000 pointers, so you can insert (up to) that many without it having to reallocate.

At least in my experience, it's fairly unusual for either of these to make a huge difference in performance--but either can affect correctness under some circumstances. In particular, as long as no reallocation takes place, iterators into the vector are guaranteed to remain valid, and once you've set the size/reserved space, you're guaranteed there won't be any reallocations as long as you don't increase the size beyond that.

I think the problem you're having is that your JSON is a list of objects when it comes in and it doesnt directly relate to your root class.

var content would look something like this (i assume):

[
  {
    "id": 3636,
    "is_default": true,
    "name": "Unit",
    "quantity": 1,
    "stock": "100000.00",
    "unit_cost": "0"
  },
  {
    "id": 4592,
    "is_default": false,
    "name": "Bundle",
    "quantity": 5,
    "stock": "100000.00",
    "unit_cost": "0"
  }
]

Note: make use of http://jsonviewer.stack.hu/ to format your JSON.

So if you try the following it should work:

  public static List<RootObject> GetItems(string user, string key, Int32 tid, Int32 pid)
    {
        // Customize URL according to geo location parameters
        var url = string.Format(uniqueItemUrl, user, key, tid, pid);

        // Syncronious Consumption
        var syncClient = new WebClient();

        var content = syncClient.DownloadString(url);

        return JsonConvert.DeserializeObject<List<RootObject>>(content);

    }

You will need to then iterate if you don't wish to return a list of RootObject.

I went ahead and tested this in a Console app, worked fine.

In Sql Server 2008 R2 database files you can connect with

Server=np:\\.\pipe\YourInstance\tsql\query;InitialCatalog=yourDataBase;Trusted_Connection=True;

only, but in sql Server 2012 you can use this:

Server=(localdb)\v11.0;Integrated Security=true;Database=DB1;

and it depended on your .mdf .ldf version.

for finding programmicaly i use this Method that explained in this post

You have an old password in the settings.xml. It is trying to connect to the repositories, but is not able to, since the password is not updated. Once you update and re-run the command, you should be good.

Im also suffered from this problem & simply, by adding port number after the ip address saved me.

$dsn = 'mysql:dbname=sms_messenger;host=127.0.0.1:8889';
$user = 'root';
$password = 'root';

This works for Mac OS

If you don't know your mysql port number, then
You can easily find the port number on MAMP home page

OR

Type following command while running the MAMP server to switch the terminal into mysql

OMBP:mamp Omal$ /Applications/MAMP/Library/bin/mysql --host=localhost -uroot -proot

Then type

mysql> SHOW GLOBAL VARIABLES LIKE 'PORT';

You don't need to control your checkBoxes with jQuery. You can do it with some simple JavaScript.

This JS snippet should work fine:

document.TheFormHere.test.Value = true;

Try this:

package my_default;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.Iterator;

import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.xssf.usermodel.XSSFCell;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

public class Test {

    public static void main(String[] args) {
        try {
        // Create Workbook instance holding reference to .xlsx file
        XSSFWorkbook workbook = new XSSFWorkbook();

        // Get first/desired sheet from the workbook
        XSSFSheet sheet = createSheet(workbook, "Sheet 1", false);

        // XSSFSheet sheet = workbook.getSheetAt(1);//Don't use this line
        // because you get Sheet index (1) is out of range (no sheets)

        //Write some information in the cells or do what you want
        XSSFRow row1 = sheet.createRow(0);
        XSSFCell r1c2 = row1.createCell(0);
        r1c2.setCellValue("NAME");
        XSSFCell r1c3 = row1.createCell(1);
        r1c3.setCellValue("AGE");


        //Save excel to HDD Drive
        File pathToFile = new File("D:\\test.xlsx");
        if (!pathToFile.exists()) {
            pathToFile.createNewFile();
        }
        FileOutputStream fos = new FileOutputStream(pathToFile);
        workbook.write(fos);
        fos.close();
        System.out.println("Done");
    } catch (Exception e) {
        e.printStackTrace();
    }
}

private static XSSFSheet createSheet(XSSFWorkbook wb, String prefix, boolean isHidden) {
    XSSFSheet sheet = null;
    int count = 0;

    for (int i = 0; i < wb.getNumberOfSheets(); i++) {
        String sName = wb.getSheetName(i);
        if (sName.startsWith(prefix))
            count++;
    }

    if (count > 0) {
        sheet = wb.createSheet(prefix + count);
    } else
        sheet = wb.createSheet(prefix);

    if (isHidden)
        wb.setSheetHidden(wb.getNumberOfSheets() - 1, XSSFWorkbook.SHEET_STATE_VERY_HIDDEN);

        return sheet;
    }

}

I just created this js function using the jQuery size function http://api.jquery.com/size/

function classCount(name){
  alert($('.'+name).size())
}

It alerts out the number of times the class name occurs in the document.

Set FormsBorderStyle of the Form to None.

If you do, it's up to you how to implement the dragging and closing functionality of the window.

For primitive array types, you would have to write a reverse sort algorithm:

Alternatively, you can convert your int[] to Integer[] and write a comparator:

public class IntegerComparator implements Comparator<Integer> {

    @Override
    public int compare(Integer o1, Integer o2) {
        return o2.compareTo(o1);
    }
}

or use Collections.reverseOrder() since it only works on non-primitive array types.

and finally,

Integer[] a2 = convertPrimitiveArrayToBoxableTypeArray(a1);
Arrays.sort(a2, new IntegerComparator()); // OR
// Arrays.sort(a2, Collections.reverseOrder());

//Unbox the array to primitive type
a1 = convertBoxableTypeArrayToPrimitiveTypeArray(a2);

http://momentjs.com/docs/#/displaying/unix-timestamp/

You get the number of unix seconds, not milliseconds!

You you need to multiply it with 1000 or using valueOf() and don't forget to use a formatter, since you are using a non ISO 8601 format. And if you forget to pass the formatter, the date will be parsed in the UTC timezone or as an invalid date.

moment("10/15/2014 9:00", "MM/DD/YYYY HH:mm").valueOf()

 function compareValues(key, order = 'asc') {
  return function innerSort(a, b) {
    if (!a.hasOwnProperty(key) || !b.hasOwnProperty(key)) {
      // property doesn't exist on either object
      return 0;
    }

    const varA = (typeof a[key] === 'string')
      ? a[key].toUpperCase() : a[key];
    const varB = (typeof b[key] === 'string')
      ? b[key].toUpperCase() : b[key];

    let comparison = 0;
    if (varA > varB) {
      comparison = 1;
    } else if (varA < varB) {
      comparison = -1;
    }
    return (
      (order === 'desc') ? (comparison * -1) : comparison
    );
  };
}

As I know, there is no direct support, but you can use plain-ol' javascript for that:

// Cookies
function createCookie(name, value, days) {
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
        var expires = "; expires=" + date.toGMTString();
    }
    else var expires = "";               

    document.cookie = name + "=" + value + expires + "; path=/";
}

function readCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') c = c.substring(1, c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
    }
    return null;
}

function eraseCookie(name) {
    createCookie(name, "", -1);
}

You probably want to have LI rather than the UL have the background-color:

.selected li {
  background-color: red;
}

Then you want to have a dynamic class for the UL:

<ul ng-repeat="vote in votes" ng-click="setSelected()" class="{{selected}}">

Now you need to update the $scope.selected when clicking the row:

$scope.setSelected = function() {
   console.log("show", arguments, this);
   this.selected = 'selected';
}

and then un-select the previously highlighted row:

$scope.setSelected = function() {
   // console.log("show", arguments, this);
   if ($scope.lastSelected) {
     $scope.lastSelected.selected = '';
   }
   this.selected = 'selected';
   $scope.lastSelected = this;
}

Working solution:

You just need to wrap object in ()

var arr = [{_x000D_
  id: 1,_x000D_
  name: 'bill'_x000D_
}, {_x000D_
  id: 2,_x000D_
  name: 'ted'_x000D_
}]_x000D_
_x000D_
var result = arr.map(person => ({ value: person.id, text: person.name }));_x000D_
console.log(result)

in order to make sure, that you are using the latest version for your :latest tag from your registry (e.g. docker hub) you need to also pull the latest tag again. in case it changed, the diff will be downloaded and started when you docker-compose up again.

so this would be the way to go:

docker-compose stop
docker-compose rm -f
docker-compose pull   
docker-compose up -d

i glued this into an image that i run to start docker-compose and make sure images stay up-to-date: https://hub.docker.com/r/stephanlindauer/docker-compose-updater/

You don't have to use jQuery or Javascript.

Use the name tag of the select and let the form do it's job.

<select name="agent_id" id="agent_id">

There's a simply way of doing it. You define for all the rows, except the first one, the following class with properties:

.not-first-row
{
   position: relative;
   top: -20px;
}

Then you apply the class to all non-first rows and adjust the negative top value to fit your desired row space. It's easy and works way better. :) Hope it helped.

Did you check

console.table(yourArray);

jQuery UI Touch Punch just solves it all.

It's a Touch Event Support for jQuery UI. Basically, it just wires touch event back to jQuery UI. Tested on iPad, iPhone, Android and other touch-enabled mobile devices. I used jQuery UI sortable and it works like a charm.

Can't do CLOBs in a Statement.

And: (OraclePreparedStatement) ps

In my case, it is because the format of the first and last two lines of the csv file is different from the middle content of the file.

So what I do is open the csv file as a string, parse the content of the string, then use read_csv to get a dataframe.

import io
import pandas as pd

file = open(f'{file_path}/{file_name}', 'r')
content = file.read()

# change new line character from '\r\n' to '\n'
lines = content.replace('\r', '').split('\n')

# Remove the first and last 2 lines of the file
# StringIO can be considered as a file stored in memory
df = pd.read_csv(StringIO("\n".join(lines[2:-2])), header=None)

use clear:left; or clear:both in your css.

#map { float:left; width:700px; height:500px; }
 #list { float:left; width:200px; background:#eee; list-style:none; padding:0; }
 #similar { float:left; width:200px; background:#000; clear:both; } 


<div id="map"></div>        
<ul id="list"></ul>
<div id ="similar">
 this text should be below, not next to ul.
</div>

If you frequently use a large number of exceptions, you can pre-define a tuple, so you don't have to re-type them many times.

#This example code is a technique I use in a library that connects with websites to gather data

ConnectErrs  = (URLError, SSLError, SocketTimeoutError, BadStatusLine, ConnectionResetError)

def connect(url, data):
    #do connection and return some data
    return(received_data)

def some_function(var_a, var_b, ...):
    try: o = connect(url, data)
    except ConnectErrs as e:
        #do the recovery stuff
    blah #do normal stuff you would do if no exception occurred

NOTES:

1. If you, also, need to catch other exceptions than those in the pre-defined tuple, you will need to define another except block.

2. If you just cannot tolerate a global variable, define it in main() and pass it around where needed...

Below is the example of searching for a keyword in the whole list and remove that item:

public class Book
{
  public int BookId { get; set; }
  public DateTime CreatedDate { get; set; }
  public string Text { get; set; }
  public string Autor { get; set; }
  public string Source { get; set; }
}

If you want to remove a book that contains some keyword in the Text property, you can create a list of keywords and remove it from list of books:

List<Book> listToSearch = new List<Book>()
   {
        new Book(){
            BookId = 1,
            CreatedDate = new DateTime(2014, 5, 27),
            Text = " test voprivreda...",
            Autor = "abc",
            Source = "SSSS"

        },
        new Book(){
            BookId = 2,
            CreatedDate = new DateTime(2014, 5, 27),
            Text = "here you go...",
            Autor = "bcd",
            Source = "SSSS"


        }
    };

var blackList = new List<string>()
            {
                "test", "b"
            }; 

foreach (var itemtoremove in blackList)
    {
        listToSearch.RemoveAll(p => p.Source.ToLower().Contains(itemtoremove.ToLower()) || p.Source.ToLower().Contains(itemtoremove.ToLower()));
    }


return listToSearch.ToList();

You can use http://www.jsonlint.com/ to edit your json online if you don't have Notepad++.

**EDITED for Swift 4.2:

As @Koen commented, swift 4.2 allows:

guard let self = self else {
   return // Could not get a strong reference for self :`(
}

// Now self is a strong reference
self.doSomething()

P.S.: Since I am having some up-votes, I would like to recommend the reading about escaping closures.

EDITED: As @tim-vermeulen has commented, Chris Lattner said on Fri Jan 22 19:51:29 CST 2016, this trick should not be used on self, so please don't use it. Check the non escaping closures info and the capture list answer from @gbk.**

guard let `self` = self else {
   return
}
self.doSomething()

try this. (I modified the example on the purpose of making it non trivial)

import operator
import numpy as np

n=10
a = list(range(n))
a1 = [1]*len(a)
an = np.array(a)

operator.add is almost more than two times faster

%timeit map(operator.add, a, a1)

than adding with numpy

%timeit an+1

JQuery 10.1.2 has a nice show and hide functions that encapsulate the behavior you are talking about. This would save you having to write a new function or keep track of css classes.

$("new").show();

$("new").hide();

I did a work around. I had a hidden textbox to hold the value. Then, on form_onsubmit, I copied the path value, less the file name to the hidden folder. Then, set the fileInput box to "". That way, no file is uploaded. I don't recall the event of the fileUpload control. Maybe onchange. It's been a while. If there's a value, I parse off the file name and put the folder back to the box. Of, course you'd validate that the file as a valid file. This would give you the clients workstation folder.
However, if you want to reflect server paths, that requires a whole different coding approach.

@Bean was created to avoid coupling Spring and your business rules in compile time. It means you can reuse your business rules in other frameworks like PlayFramework or JEE.

Moreover, you have total control on how create beans, where it is not enough the default Spring instantation.

I wrote a post talking about it.

In one controller, you can do:

$rootScope.$broadcast('eventName', data);

and listen to the event in another:

$scope.$on('eventName', function (event, data) {...});

Select cell B2 and click "Freeze Panes" this will freeze Row 1 and Column A.

For future reference, selecting Freeze Panes in Excel will freeze the rows above your selected cell and the columns to the left of your selected cell. For example, to freeze rows 1 and 2 and column A, you could select cell B3 and click Freeze Panes. You could also freeze columns A and B and row 1, by selecting cell C2 and clicking "Freeze Panes".

For completeness sake, also a solution with Joda-Time version 2.5 and its DateTime class:

new Timestamp(new DateTime(2007, 9, 23, 0, 0, DateTimeZone.forID( "America/Montreal" )).getMillis())

That this works is not trivial at all! It's a property of the IEEE floating point representation that int°floor = ?·? if the magnitude of the numbers in question is small enough, but different representations are possible where int(floor(2.3)) might be 1.

This post explains why it works in that range.

In a double, you can represent 32bit integers without any problems. There cannot be any rounding issues. More precisely, doubles can represent all integers between and including 2⁵³ and -2⁵³.

Short explanation: A double can store up to 53 binary digits. When you require more, the number is padded with zeroes on the right.

It follows that 53 ones is the largest number that can be stored without padding. Naturally, all (integer) numbers requiring less digits can be stored accurately.

Adding one to 111(omitted)111 (53 ones) yields 100...000, (53 zeroes). As we know, we can store 53 digits, that makes the rightmost zero padding.

This is where 2⁵³ comes from.

More detail: We need to consider how IEEE-754 floating point works.

  1 bit    11 / 8     52 / 23      # bits double/single precision
[ sign |  exponent | mantissa ]

The number is then calculated as follows (excluding special cases that are irrelevant here):

-1^sign × 1.mantissa ×2^{exponent - bias}

where bias = 2^{exponent - 1} - 1, i.e. 1023 and 127 for double/single precision respectively.

Knowing that multiplying by 2^X simply shifts all bits X places to the left, it's easy to see that any integer must have all bits in the mantissa that end up right of the decimal point to zero.

Any integer except zero has the following form in binary:

1x...x where the x-es represent the bits to the right of the MSB (most significant bit).

Because we excluded zero, there will always be a MSB that is one—which is why it's not stored. To store the integer, we must bring it into the aforementioned form: -1^sign × 1.mantissa ×2^{exponent - bias}.

That's saying the same as shifting the bits over the decimal point until there's only the MSB towards the left of the MSB. All the bits right of the decimal point are then stored in the mantissa.

From this, we can see that we can store at most 52 binary digits apart from the MSB.

It follows that the highest number where all bits are explicitly stored is

111(omitted)111.   that's 53 ones (52 + implicit 1) in the case of doubles.

For this, we need to set the exponent, such that the decimal point will be shifted 52 places. If we were to increase the exponent by one, we cannot know the digit right to the left after the decimal point.

111(omitted)111x.

By convention, it's 0. Setting the entire mantissa to zero, we receive the following number:

100(omitted)00x. = 100(omitted)000.

That's a 1 followed by 53 zeroes, 52 stored and 1 added due to the exponent.

It represents 2⁵³, which marks the boundary (both negative and positive) between which we can accurately represent all integers. If we wanted to add one to 2⁵³, we would have to set the implicit zero (denoted by the x) to one, but that's impossible.

Create the war file in a different directory to where the content is otherwise the jar command might try to zip up the file it is creating.

#!/bin/bash

set -euo pipefail

war=app.war
src=contents

# Clean last war build
if [ -e ${war} ]; then
    echo "Removing old war ${war}"
    rm -rf ${war}
fi

# Build war
if [ -d ${src} ]; then
    echo "Found source at ${src}"
    cd ${src}
    jar -cvf ../${war} *
    cd ..
fi

# Show war details
ls -la ${war}

Like R. Bemrose suggested, if you are doing Windows 7 specific features, you should look at the Windows® API Code Pack for Microsoft® .NET Framework.

It contains a CoreHelpers class that let you determine the OS you are currently on (XP and above only, its a requirement for .NET nowaday)

It also provide multiple helper methods. For example, suppose that you want to use the jump list of Windows 7, there is a class TaskbarManager that provide a property called IsPlatformSupported and it will return true if you are on Windows 7 and above.

Using jquery's map function

var checkboxValues = [];
$('input[name=checkboxName]:checked').map(function() {
            checkboxValues.push($(this).val());
});

An other solution rm(list=ls(pattern="temp")), remove all objects matching the pattern.

If appropriate, you might use a Dictionary which is also a generic collection:

Dictionary<string, int> d = new Dictionary<string, int>();
d.Add("string", 1);

This is just some additional information that might help anyone. I want to make it abundantly clear that what I am describing here is possibly:

• A. not 100% correct and
• B. not safe in terms of network security.

I am not a DBA, but every time I find myself setting up a SQL Server (Express or Full) for testing or what not I run into the connectivity issue. The solution I am describing is more for the person who is just trying to get their job done - consult someone who is knowledgeable in this field when setting up a production server.

For SQL Server 2008 R2 this is what I end up doing:

1. Make sure everything is squared away like in this tutorial which is the same tutorial posted above as a solution by "Dani" as the selected answer to this question.
2. Check and/or set, your firewall settings for the computer that is hosting the SQL Server. If you are using a Windows Server 2008 R2 then use the Server Manager, go to Configuration and then look at "Windows Firewall with Advanced Security". If you are using Windows 7 then go to Control Panel and search for "Firewall" click on "Allow a program through Windows Firewall".
   • Create an inbound rule for port TCP 1433 - allow the connection
   • Create an outbound rule for port TCP 1433 - allow the connection
3. When you are finished with the firewall settings you are going to want to check one more thing. Open up the "SQL Server Configuration Manager" locate: SQL Server Network Configuration - Protocols for SQLEXPRESS (or equivalent) - TCP/IP
   • Double click on TCP/IP
   • Click on the IP Addresses tab
   • Under IP1 set the TCP Port to 1433 if it hasn't been already
   • Under IP All set the TCP Port to 1433 if it hasn't been already
4. Restart SQL Server and SQL Browser (do both just to be on the safe side)

Usually after I do what I mentioned above I don't have a problem anymore. Here is a screenshot of what to look for - for that last step:

Again, if someone with more information about this topic sees a red flag please correct me.

you can use Realm or Sqlite if you want to manage complex data type.

Otherwise go with inbuilt react native asynstorage

Change android:stretchColumns value to *.

Value 0 means stretch the first column. Value 1 means stretch the second column and so on.

Value * means stretch all the columns.

To retrieve the entire querystring from the current URL, beginning with the ? character, you can use

location.search

https://developer.mozilla.org/en-US/docs/DOM/window.location

Example:

// URL = https://example.com?a=a%20a&b=b123
console.log(location.search); // Prints "?a=a%20a&b=b123" 

In regards to retrieving specific querystring parameters, while although classes like URLSearchParams and URL exist, they aren't supported by Internet Explorer at this time, and should probably be avoided. Instead, you can try something like this:

/**
 * Accepts either a URL or querystring and returns an object associating 
 * each querystring parameter to its value. 
 *
 * Returns an empty object if no querystring parameters found.
 */
function getUrlParams(urlOrQueryString) {
  if ((i = urlOrQueryString.indexOf('?')) >= 0) {
    const queryString = urlOrQueryString.substring(i+1);
    if (queryString) {
      return _mapUrlParams(queryString);
    } 
  }

  return {};
}

/**
 * Helper function for `getUrlParams()`
 * Builds the querystring parameter to value object map.
 *
 * @param queryString {string} - The full querystring, without the leading '?'.
 */
function _mapUrlParams(queryString) {
  return queryString    
    .split('&') 
    .map(function(keyValueString) { return keyValueString.split('=') })
    .reduce(function(urlParams, [key, value]) {
      if (Number.isInteger(parseInt(value)) && parseInt(value) == value) {
        urlParams[key] = parseInt(value);
      } else {
        urlParams[key] = decodeURI(value);
      }
      return urlParams;
    }, {});
}

You can use the above like so:

// Using location.search
let urlParams = getUrlParams(location.search); // Assume location.search = "?a=1&b=2b2"
console.log(urlParams); // Prints { "a": 1, "b": "2b2" }

// Using a URL string
const url = 'https://example.com?a=A%20A&b=1';
urlParams = getUrlParams(url);
console.log(urlParams); // Prints { "a": "A A", "b": 1 }

// To check if a parameter exists, simply do:
if (urlParams.hasOwnProperty('parameterName') { 
  console.log(urlParams.parameterName);
}
