Change position:absolute to position:fixed;.

Example can be found in this jsFiddle.

tableB.col1 = tableA.col1 
OR tableB.col2 = tableA.col1  
OR tableB.col1 = tableA.col2  
OR tableB.col1 = tableA.col2

Partly, because Go doesn't have generics (so you would need one set-type for every type, or fall back on reflection, which is rather inefficient).

Partly, because if all you need is "add/remove individual elements to a set" and "relatively space-efficient", you can get a fair bit of that simply by using a map[yourtype]bool (and set the value to true for any element in the set) or, for more space efficiency, you can use an empty struct as the value and use _, present = the_setoid[key] to check for presence.

Two things occur to me.

First, are you sure you mean ManyToOne for address? That means multiple people will have the same address. If it's edited for one of them, it'll be edited for all of them. Is that your intent? 99% of the time addresses are "private" (in the sense that they belong to only one person).

Secondly, do you have any other eager relationships on the Person entity? If I recall correctly, Hibernate can only handle one eager relationship on an entity but that is possibly outdated information.

I say that because your understanding of how this should work is essentially correct from where I'm sitting.

Use compareTo() function that's built into the class.

I had the same problem, i solved it by:
1 - i uninstall virtual box
2 - i uninstall genymotion with all new folder that dependency
3 - download latest version of virtual box(from oracle site)
4 - download latest version of Genymotion(without virtual box version
size:about42M)
5 - first install virtual box
6 - install genymotion
7 - before run genymotion you should restart your windows os
8 - run genymotion as admin

In the IIS Manager, under Authentication, disable: 1) Anonymous Authentication 2) Forms Authentication

Then add the following to your controller, to handle testing versus server deployment:

string sUserName = null;
string url = Request.Url.ToString();

if (url.Contains("localhost"))
  sUserName = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
else
  sUserName = User.Identity.Name;

I'm also having the exact same problem with both /usr/local/bin and /etc/sudoers on OSX Snow lepard.Even when i logged in as admin and tried to change the permissions via the terminal, it still says "Operation not permitted". And i did the following to get the permission of these folders.

From the terminal, I accessed /etc/sudoers file and using pico editor i added the following code: username ALL=(ALL) ALL Replace "username" with your MAC OS account name

When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.

With Basic Auth, the HTTP request from the question will look something like this:

GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk

The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password).

To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl, the username and password will be clearly visible on the process list and might turn up in the bash history file.

When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.

Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.

When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.

Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.

I just put into constructor something by reference, so the subform can change its value and main form can get new or modified object from subform.

You can un-check the build automatically in Project menu and then build by hand by type Ctrl + B, or clicking an icon the appears to the right of the printer icon.

I've just started using Java on Eclipse (Juno) after a 15 year break from Java. I was using the ADK on a 1.6GHz Atom N270 with 4Gb RAM on W7 32bit on a nearly empty disk. Not sure if it is the Atom or whether Java is as bad as it used to be 15 years ago but it takes over 2 minutes for Eclipse to even start. The emulator does turn up eventually but is extremely sluggish. Even without the emulator, Eclipse is sluggish.

On a 1.6GHz Core i7 or a 2GHz Core 2 Duo, operation is reasonable. Emulator works, Eclipse takes about 5 to 10 seconds to be ready for work. Moral of the story: don't use an Atom or any other low powered processor. It is sluggish even with 4Gb memory and having the same clock speed as a high end processor.

I've also tried it in a VMWare VM on the 1.6GHz Core i7 and on the Core 2. It is reasonably fast until the the emulator is started. It then slows down to the point of no return. Redraws is now very much like that of the Atom but at least it responds when the buttons are clicked. Note that it is now running an emulator within an emulator. The only problem with VMs is that every so often W7 does what W7 does. There is a wait cursor and whole machine is totally unresponsive for a minute or two then it springs back to life. This was with VMWare V3. V4/V5 might be different. Varying the number of cores/processors did not make any difference to eclipse or the emulator.

My preferred solution for this would be to do the resizing server-side, so you are transmitting less unnecessary data.

If you have to do it client-side though, and need to keep the image ratio, you could use the below:

var image_from_ajax = new Image();
image_from_ajax.src = fetch_image_from_ajax(); // Downloaded via ajax call?

image_from_ajax = rescaleImage(image_from_ajax);

// Rescale the given image to a max of max_height and max_width
function rescaleImage(image_name)
{
    var max_height = 100;
    var max_width = 100;

    var height = image_name.height;
    var width = image_name.width;
    var ratio = height/width;

    // If height or width are too large, they need to be scaled down
    // Multiply height and width by the same value to keep ratio constant
    if(height > max_height)
    {
        ratio = max_height / height;
        height = height * ratio;
        width = width * ratio;
    }

    if(width > max_width)
    {
        ratio = max_width / width;
        height = height * ratio;
        width = width * ratio;
    }

    image_name.width = width;
    image_name.height = height;
    return image_name;
}

Passive event listeners are an emerging web standard, new feature shipped in Chrome 51 that provide a major potential boost to scroll performance. Chrome Release Notes.

It enables developers to opt-in to better scroll performance by eliminating the need for scrolling to block on touch and wheel event listeners.

Problem: All modern browsers have a threaded scrolling feature to permit scrolling to run smoothly even when expensive JavaScript is running, but this optimization is partially defeated by the need to wait for the results of any touchstart and touchmove handlers, which may prevent the scroll entirely by calling preventDefault() on the event.

Solution: {passive: true}

By marking a touch or wheel listener as passive, the developer is promising the handler won't call preventDefault to disable scrolling. This frees the browser up to respond to scrolling immediately without waiting for JavaScript, thus ensuring a reliably smooth scrolling experience for the user.

document.addEventListener("touchstart", function(e) {
    console.log(e.defaultPrevented);  // will be false
    e.preventDefault();   // does nothing since the listener is passive
    console.log(e.defaultPrevented);  // still false
}, Modernizr.passiveeventlisteners ? {passive: true} : false);

Instead of Button use LinearLayout with ImageView and TextView inside. In child items like ImageView and TextView use android:duplicateParentState="true".

Executive summary: it's 64 bits, or larger.

unsigned long long is the same as unsigned long long int. Its size is platform-dependent, but guaranteed by the C standard (ISO C99) to be at least 64 bits. There was no long long in C89, but apparently even MSVC supports it, so it's quite portable.

In the current C++ standard (issued in 2003), there is no long long, though many compilers support it as an extension. The upcoming C++0x standard will support it and its size will be the same as in C, so at least 64 bits.

You can get the exact size, in bytes (8 bits on typical platforms) with the expression sizeof(unsigned long long). If you want exactly 64 bits, use uint64_t, which is defined in the header <stdint.h> along with a bunch of related types (available in C99, C++11 and some current C++ compilers).

I just built a sandbox environment with your code and it worked for me. Here is what I used:

<html>
  <head>
    <title>test</title>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
  </head>
  <body>
    <form id="chatTickets" method="post" action="/admin/index.cfm/">
      <input id="ticketID1" type="radio" checked="checked" value="myvalue1" name="ticketID"/>
      <input id="ticketID2" type="radio" checked="checked" value="myvalue2" name="ticketID"/>
    </form>
    <a href="#" title="Load ActiveChat" id="loadActive">Load Active</a>

    <script>
      jQuery("#loadActive").click(function() {
        //I have other code in here that runs before this function call
        writeData();
      });
      function writeData() {
        jQuery("input[name='ticketID']").each(function(i) {
            jQuery(this).attr('disabled', 'disabled');
        });
      }
    </script>
  </body>
</html>

I tested in FF3.5, moving to IE8 now. And it works fine in IE8 too. What browser are you using?

Button btn=(Button)findViewById(R.id.btn);
String btnText=btn.getText().toString();

Later this btnText can be used .

For example:

if(btnText == "Text for comparison")

Swift 3 / Swift 4 Update:

let screenSize: CGRect = UIScreen.main.bounds
let myView = UIView(frame: CGRect(x: 0, y: 0, width: screenSize.width - 10, height: 10))
self.view.addSubview(myView)

I've made a category from @Abizern answer

@implementation NSString (Extensions)
- (NSDictionary *) json_StringToDictionary {
    NSError *error;
    NSData *objectData = [self dataUsingEncoding:NSUTF8StringEncoding];
    NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData options:NSJSONReadingMutableContainers error:&error];
    return (!json ? nil : json);
}
@end

Use it like this,

NSString *jsonString = @"{\"2\":\"3\"}";
NSLog(@"%@",[jsonString json_StringToDictionary]);

To fix this problem, you have to install OpenSSL development package, which is available in standard repositories of all modern Linux distributions.

To install OpenSSL development package on Debian, Ubuntu or their derivatives:

$ sudo apt-get install libssl-dev

To install OpenSSL development package on Fedora, CentOS or RHEL:

$ sudo yum install openssl-devel 

Edit : As @isapir has pointed out, for Fedora version>=22 use the DNF package manager :

dnf install openssl-devel

=ROUND((TODAY()-A1)/365,0) will provide number of years between date in cell A1 and today's date

You can use substr:

echo substr('a,b,c,d,e,', 0, -1);
# => 'a,b,c,d,e'

To center align text

input[type='text'] { text-align:center;}

To center align the textbox in the container that it sits in, apply text-align:center to the container.

I have read that any variable declared outside a function is a global variable. I have done so, but in another *.cpp File that variable could not be found. So it was not realy global.

According to the concept of scope, your variable is global. However, what you've read/understood is overly-simplified.

Possibility 1

Perhaps you forgot to declare the variable in the other translation unit (TU). Here's an example:

a.cpp

int x = 5; // declaration and definition of my global variable

b.cpp

// I want to use `x` here, too.
// But I need b.cpp to know that it exists, first:
extern int x; // declaration (not definition)

void foo() {
   cout << x;  // OK
}

Typically you'd place extern int x; in a header file that gets included into b.cpp, and also into any other TU that ends up needing to use x.

Possibility 2

Additionally, it's possible that the variable has internal linkage, meaning that it's not exposed across translation units. This will be the case by default if the variable is marked const ([C++11: 3.5/3]):

a.cpp

const int x = 5; // file-`static` by default, because `const`

b.cpp

extern const int x;    // says there's a `x` that we can use somewhere...

void foo() {
   cout << x;    // ... but actually there isn't. So, linker error.
}

You could fix this by applying extern to the definition, too:

a.cpp

extern const int x = 5;

This whole malarky is roughly equivalent to the mess you go through making functions visible/usable across TU boundaries, but with some differences in how you go about it.

This question was not fully answered, since module privacy is not purely conventional, and since using import may or may not recognize module privacy, depending on how it is used.

If you define private names in a module, those names will be imported into any script that uses the syntax, 'import module_name'. Thus, assuming you had correctly defined in your example the module private, _num, in a.py, like so..

#a.py
_num=1

..you would be able to access it in b.py with the module name symbol:

#b.py
import a
...
foo = a._num # 1

To import only non-privates from a.py, you must use the from syntax:

#b.py
from a import *
...
foo = _num # throws NameError: name '_num' is not defined

For the sake of clarity, however, it is better to be explicit when importing names from modules, rather than importing them all with a '*':

#b.py
from a import name1 
from a import name2
...

perl one-liner alert

just for fun... print only one line after match

perl -lne '$next = ($.+1) if /match/; $. == $next && print' data.txt

even more fun... print the next ten lines after match

perl -lne 'push @nexts, (($.+1)..($.+10)) if /match/; $. ~~ @nexts && print' data.txt

kinda cheating though since there's actually two commands

The following should work in an angular CLI 6 project. I.e if you are getting:

get/set have been deprecated in favor of the config command.

npm install node-sass --save-dev

Then (making sure you change the project name)

ng config projects.YourPorjectName.schematics.@schematics/angular:component.styleext sass

To get your default project name use:

ng config defaultProject

However: If you have migrated your project from <6 up to angular 6 there is a good chance that the config wont be there. In which case you might get:

Invalid JSON character: "s" at 0:0

Therefore a manual editing of angular.json will be required.

You will want it to look something like this (taking note of the styleex property):

...
"projects": {
    "Sassy": {
      "root": "",
      "sourceRoot": "src",
      "projectType": "application",
      "prefix": "app",
      "schematics": {
        "@schematics/angular:component": {
          "styleext": "scss"
        }
      }
...

Seems like an overly complex schema to me. ¯_(?)_/¯

You will now have to go and change all your css/less files to be scss and update any references in components etc, but you should be good to go.

Use the RIGHT function... e.g.

DECLARE @testnum TINYINT
SET @testnum = 3
PRINT RIGHT('00' + CONVERT(VARCHAR(2), @testnum), 2)

This problem becomes apparent when you try to host a react app in github pages.

How I fixed this,

In in my main application file, called app.tsx, where I include the router. I set the basename, eg, <BrowserRouter basename="/Seans-TypeScript-ReactJS-Redux-Boilerplate/">

Note that it is a relative url, this completely simplifies the ability to run locally and hosted. The basename value, matches the repository title on GitHub. This is the path that GitHub pages will auto create.

That is all I needed to do.

See working example hosted on GitHub pages at

https://sean-bradley.github.io/Seans-TypeScript-ReactJS-Redux-Boilerplate/

I think you conclusions are correct but not accurate.

As the docs indicates, socket.recv is majorly focused on the network buffers.

When socket is blocking, socket.recv will return as long as the network buffers have bytes. If bytes in the network buffers are more than socket.recv can handle, it will return the maximum number of bytes it can handle. If bytes in the network buffers are less than socket.recv can handle, it will return all the bytes in the network buffers.

If nothing mentioned in the above comments is working for you. It might mean the problem lies somewhere else.

One place I found the solution was in the way I was setting the list to the adapter. In my activity the list was a instance variable and I was changing it directly when any data changed. Due to it being a reference variable there was something weird going on. So I changed the reference variable to a local one and used another variable to update data and then pass to addAll() function mentioned in above answers.

According to https://developers.google.com/api-client-library/python/apis/oauth2/v1 you need to install google-api-python-client package:

pip install --upgrade google-api-python-client

Efficient solution using date as background dedicated process

In order to make this kind of translation a lot quicker...

Intro

In this post, you will find

• a Quick Demo, following this,
• some Explanations,
• a Function useable for many Un*x tools (bc, rot13, sed...).

Quick Demo

fifo=$HOME/.fifoDate-$$
mkfifo $fifo
exec 5> >(exec stdbuf -o0 date -f - +%s >$fifo 2>&1)
echo now 1>&5
exec 6< $fifo
rm $fifo
read -t 1 -u 6 now
echo $now

This must output current UNIXTIME. From there, you could compare

time for i in {1..5000};do echo >&5 "now" ; read -t 1 -u6 ans;done
real    0m0.298s
user    0m0.132s
sys     0m0.096s

and:

time for i in {1..5000};do ans=$(date +%s -d "now");done 
real    0m6.826s
user    0m0.256s
sys     0m1.364s

From more than 6 seconds to less than a half second!!(on my host).

You could check echo $ans, replace "now" by "2019-25-12 20:10:00" and so on...

Optionaly, you could, once requirement of date subprocess ended:

exec 5>&- ; exec 6<&-

Original post (detailed explanation)

Instead of running 1 fork by date to convert, run date just 1 time and do all convertion with same process (this could become a lot quicker)!:

date -f - +%s <<eof
Apr 17  2014
May 21  2012
Mar  8 00:07
Feb 11 00:09
eof
1397685600
1337551200
1520464020
1518304140

Sample:

start1=$(LANG=C ps ho lstart 1)
start2=$(LANG=C ps ho lstart $$)
dirchg=$(LANG=C date -r .)
read -p "A date: " userdate
{ read start1 ; read start2 ; read dirchg ; read userdate ;} < <(
   date -f - +%s <<<"$start1"$'\n'"$start2"$'\n'"$dirchg"$'\n'"$userdate" )

Then now have a look:

declare -p start1 start2 dirchg userdate

(may answer something like:

declare -- start1="1518549549"
declare -- start2="1520183716"
declare -- dirchg="1520601919"
declare -- userdate="1397685600"

This was done in one execution!

Using long running subprocess

We just need one fifo:

mkfifo /tmp/myDateFifo
exec 7> >(exec stdbuf -o0 /bin/date -f - +%s >/tmp/myDateFifo)
exec 8</tmp/myDateFifo
rm /tmp/myDateFifo

(Note: As process is running and all descriptors are opened, we could safely remove fifo's filesystem entry.)

Then now:

LANG=C ps ho lstart 1 $$ >&7
read -u 8 start1
read -u 8 start2
LANG=C date -r . >&7
read -u 8 dirchg

read -p "Some date: " userdate
echo >&7 $userdate
read -u 8 userdate

We could buid a little function:

mydate() {
    local var=$1;
    shift;
    echo >&7 $@
    read -u 8 $var
}

mydate start1 $(LANG=C ps ho lstart 1)
echo $start1

HTTPUtility.HTMLEncode() is meant to handle encoding HTML tags as strings. It takes care of all the heavy lifting for you. From the MSDN Documentation:

If characters such as blanks and punctuation are passed in an HTTP stream, they might be misinterpreted at the receiving end. HTML encoding converts characters that are not allowed in HTML into character-entity equivalents; HTML decoding reverses the encoding. For example, when embedded in a block of text, the characters < and >, are encoded as < and > for HTTP transmission.

HTTPUtility.HTMLEncode() method, detailed here:

public static void HtmlEncode(
  string s,
  TextWriter output
)

Usage:

String TestString = "This is a <Test String>.";
StringWriter writer = new StringWriter();
Server.HtmlEncode(TestString, writer);
String EncodedString = writer.ToString();

$(document).on('click','[action=register]',function(){
    registerSocket(registerJSON(),registerDone,second($(this)));
});

function registerSocket(dataFn,doneFn,second){
                 $.ajax({
                       type:'POST',
                       url: "http://localhost:8080/store/public/register",
                       contentType: "application/json; charset=utf-8",
                       dataType: "json",
                       data:dataFn
                 }).done ([doneFn,second])
                   .fail(function(err){
                            console.log("AJAX failed: " + JSON.stringify(err, null, 2));
                        });
}

function registerDone(data){
    console.log(JSON.stringify(data));
}
function second(element){
    console.log(element);
}

Secondary way :

function socketWithParam(url,dataFn,doneFn,param){
  $.ajax({
    type:'POST',
    url:url,
    contentType: "application/json; charset=utf-8",
    headers: { 'Authorization': 'Bearer '+localStorage.getItem('jwt')},
    data:dataFn
    }).done(function(data){
      doneFn(data,param);
    })
    .fail(function(err,status,xhr){
    console.log("AJAX failed: " + JSON.stringify(err, null, 2));
    });
}

$(document).on('click','[order-btn]',function(){
  socketWithParam(url,fakeDataFn(),orderDetailDone,secondParam);
});

function orderDetailDone(data,param){
  -- to do something --
}

Also, the verbiage that calls ExpressJS or Connect as a "WebServer" is incorrect. You can create a basic WebServer with or without them. A basic NodeJS program can also use the http module to handle http requests, Thus becoming a rudimentary web server.

"adjustResize"

The activity's main window is always resized to make room for the soft keyboard on screen.

"adjustPan"

The activity's main window is not resized to make room for the soft keyboard. Rather, the contents of the window are automatically panned so that the current focus is never obscured by the keyboard and users can always see what they are typing. This is generally less desirable than resizing, because the user may need to close the soft keyboard to get at and interact with obscured parts of the window.

MSSQL have its own database management tool called as "MSSQL Server Management Studio (SSMS)". Here are steps to reset SA password using SSMS :

1] Open SSMS management console, it will prompt for authentication details,

Select Server Type : "Database Engine", Server name : IP / hostname of your MSSQL server Authentication : Windows Authentication

Once you select Authentication type as "Windows Authentication", the user name and password fields will be grayed out and it will allow you to login SQL server without entering login details. Windows Authentication is possible only when you are logged on same server in RDP on which SQL service is present.

2] once you are in, under "Object Explorer" expand Security and then Logins 3] locate and right click on user SA and select Properties 4] under General section enter desired password in front of "Password:" and "Confirm Password:" 5] hit OK at bottom.

This is the easiest and secure way to reset SA password instead of using any third party non secure tools

Iterate through each number with for...of statement.

By adding a + sign before a String, it will be converted into a number.

const num = 143,
  digits = [];

for (const digit of `${num}`) {
  digits.push(+digit)
}
console.log(digits);

Inspired by @iampopov You can write it with spread syntax.

const num = 143;
const digits = [...`${num}`].map(Number);
console.log(digits);

1. Does it work if you remove the AddType line? I'm not quite sure why that's relevant to turning magic quotes off.

2. If PHP isn't running under mod_php, htaccess won't work. Does it work as a CGI?

This is one for your hosting company really.

This trick worked for me in Eclipse Luna (4.4.2): For a jar file I am using (htsjdk), I packed the source in a separate jar file (named htsjdk-2.0.1-src.jar; I could do this since htsjdk is open source) and stored it in the lib-src folder of my project. In my own Java source I selected an element I was using from the jar and hit F3 (Open declaration). Eclipse opened the class file and showed the button "Attach source". I clicked the button and pointed to the src jar file I had just put into the lib-src folder. Now I get the Javadoc when hovering over anything I’m using from the jar.

A bit late to the party, but that's why I wrote jenny, a small reimplementation of some core Jenkinsfile steps. (https://github.com/bmustiata/jenny)

One of the reasons why everyone has a slightly different definition is because Subversion implements zero support for branches and tags. Subversion basically says: We looked at full-featured branches and tags in other systems and did not found them useful, so we did not implement anything. Just make a copy into a new directory with a name convention instead. Then of course everyone is free to have slightly different conventions. To understand the difference between a real tag and a mere copy + naming convention see the Wikipedia entry Subversion tags & branches.

Create a copy of executables of same service and paste it on the same path of the existing service and then uninstall.

For adding unique index following are required:

1) table_name
2) index_name
3) columns on which you want to add index

ALTER TABLE  `tablename` 
ADD UNIQUE index-name
(`column1` ,`column2`,`column3`,...,`columnN`);

In your case we can create unique index as follows:

ALTER TABLE `votes`ADD 
UNIQUE <votesuniqueindex>;(`user` ,`email`,`address`);

Collision with fast-moving objects is always a problem. A good way to ensure that you detect all collision is to use Raycasting instead of relying on the physics simulation. This works well for bullets or small objects, but will not produce good results for large objects. http://unity3d.com/support/documentation/ScriptReference/Physics.Raycast.html

Pseudo-codeish (I don't have code-completion here and a poor memory):

void FixedUpdate()
{
    Vector3 direction = new Vector3(transform.position - lastPosition);
    Ray ray = new Ray(lastPosition, direction);
    RaycastHit hit;
    if (Physics.Raycast(ray, hit, direction.magnitude))
    {
        // Do something if hit
    }

    this.lastPosition = transform.position;
}

You can't run a specific show index query because it will throw an error if an index does not exist. Therefore, you have to grab all indexes into an array and loop through them if you want to avoid any SQL errors.

Heres how I do it. I grab all of the indexes from the table (in this case, leads) and then, in a foreach loop, check if the column name (in this case, province) exists or not.

$this->name = 'province';

$stm = $this->db->prepare('show index from `leads`');
$stm->execute();
$res = $stm->fetchAll();
$index_exists = false;

foreach ($res as $r) {
    if ($r['Column_name'] == $this->name) {
        $index_exists = true;
    }
}

This way you can really narrow down the index attributes. Do a print_r of $res in order to see what you can work with.

Much more simple: Right click -> Refactor -> Move.

I had this problem.When I define firefox path my problem had been solved.

import webbrowser
urL='https://www.python.org'
mozilla_path="C:\\Program Files\\Mozilla Firefox\\firefox.exe"
webbrowser.register('firefox', None,webbrowser.BackgroundBrowser(mozilla_path))
webbrowser.get('firefox').open_new_tab(urL)

During testing I found that foreach loop after break go to the loop beging and not out of the loop. So I changed foreach into for and break in this case work correctly- after break program flow goes out of the loop.

1. Go to Control Panel -> Programs -> Programs and features

   

2. Go to Windows Features and disable Internet Explorer 11

   

   

3. Then click on Display installed updates

   

4. Search for Internet explorer

5. Right-click on Internet Explorer 11 -> Uninstall

   

6. Do the same with Internet Explorer 10

7. Restart your computer
8. Install Internet Explorer 10 here (old broken link)

I think it will be okay.

- (void)viewDidLoad

   [self.tableView setSeparatorColor:[UIColor myColor]];

I hope that helps - you'll need the self. to access it, remember.

Swift 4.2

tableView.separatorColor = UIColor.red

If you not use maven, try to put your jars to WEB-INF/lib, it worked for me.

Using IReadOnlyCollection<T> or IReadOnlyList<T> in the method signature instead of IEnumerable<T>, has the advantage of making explicit that you might need to check the count before iterating, or to iterate multiple times for some other reason.

However they have a huge downside that will cause problems if you try to refactor your code to use interfaces, for instance to make it more testable and friendly to dynamic proxying. The key point is that IList<T> does not inherit from IReadOnlyList<T>, and similarly for other collections and their respective read-only interfaces. (In short, this is because .NET 4.5 wanted to keep ABI compatibility with earlier versions. But they didn't even take the opportunity to change that in .NET core.)

This means that if you get an IList<T> from some part of the program and want to pass it to another part that expects an IReadOnlyList<T>, you can't! You can however pass an IList<T> as an IEnumerable<T>.

In the end, IEnumerable<T> is the only read-only interface supported by all .NET collections including all collection interfaces. Any other alternative will come back to bite you as you realize that you locked yourself out from some architecture choices. So I think it's the proper type to use in function signatures to express that you just want a read-only collection.

(Note that you can always write a IReadOnlyList<T> ToReadOnly<T>(this IList<T> list) extension method that simple casts if the underlying type supports both interfaces, but you have to add it manually everywhere when refactoring, where as IEnumerable<T> is always compatible.)

As always this is not an absolute, if you're writing database-heavy code where accidental multiple enumeration would be a disaster, you might prefer a different trade-off.

Implement in this way

String i="hi";
Intent i = new Intent(this, ActivityTwo.class);
//Create the bundle
Bundle b = new Bundle();
//Add your data to bundle
b.putString(“stuff”, i);
i.putExtras(b);
startActivity(i);

Begin that second activity, inside this class to utilize the Bundle values use this code

Bundle bundle = getIntent().getExtras();
String text= bundle.getString("stuff");

I think that is controlled by the expose_php setting in PHP.ini:

expose_php = off

Decides whether PHP may expose the fact that it is installed on the server (e.g. by adding its signature to the Web server header). It is no security threat in any way, but it makes it possible to determine whether you use PHP on your server or not.

There is no direct security risk, but as David C notes, exposing an outdated (and possibly vulnerable) version of PHP may be an invitation for people to try and attack it.

Here are a couple of ways.

The first will order things based on the order seen in the data frame:

x$variable <- factor(x$variable, levels=unique(as.character(x$variable)) )

The second orders the levels based on another variable (value in this case):

x <- transform(x, variable=reorder(variable, -value) ) 

var list = [
    { date: '12/1/2011', reading: 3, id: 20055 },
    { date: '13/1/2011', reading: 5, id: 20053 },
    { date: '14/1/2011', reading: 6, id: 45652 }
];

and then access it:

alert(list[1].date);

The proper syntax would be - ALTER TABLE Table_Name ADD UNIQUE (column_name)

Example

ALTER TABLE  0_value_addition_setup ADD UNIQUE (`value_code`)

I've been searching the internet for RNG for a while now. Everything I saw was either TOO complex or was just not what I was looking for. After reading a few articles I was able to come up with this simple code.

{
  Random rnd = new Random(DateTime.Now.Millisecond);
  int[] b = new int[10] { 5, 8, 1, 7, 3, 2, 9, 0, 4, 6 };
  textBox1.Text = Convert.ToString(b[rnd.Next(10)])
}

Simple explanation,

1. create a 1 dimensional integer array.
2. full up the array with unordered numbers.
3. use the rnd.Next to get the position of the number that will be picked.

This works well.

To obtain a random number less than 100 use

{
  Random rnd = new Random(DateTime.Now.Millisecond);
  int[] b = new int[10] { 5, 8, 1, 7, 3, 2, 9, 0, 4, 6 };
  int[] d = new int[10] { 9, 4, 7, 2, 8, 0, 5, 1, 3, 4 };
  textBox1.Text = Convert.ToString(b[rnd.Next(10)]) + Convert.ToString(d[rnd.Next(10)]);
}

and so on for 3, 4, 5, and 6 ... digit random numbers.

Hope this assists someone positively.

.disabledLink.disabled {pointer-events:none;}

That should do it hope I helped!

After a couple of csv file downloads (lots of tests) chrome asked whether to allow more downloads from this page. I just dismissed the window. After that chrome did not download the file any more but the console sayed:

"Resource interpreted as Document but transferred with MIME type text/csv"

I could solve that issue by restarting chrome (completely Ctrl-Shift-Q).

[Update] Not sure why this post was deleted but it provided the solution for me. I had gotten the message earlier about trying to download multiple files and must have answered no. I got the "Resource interpreted..." message until I restarted the browser; then it worked perfectly. For some cases, this may be the right answer.

Here is an elegant library that records video in all supported browsers and supports uploading:

UPDATE
From v0.20, melt is a first order function, you can now use

df.melt(id_vars=["location", "name"], 
        var_name="Date", 
        value_name="Value")

  location    name        Date  Value
0        A  "test"    Jan-2010     12
1        B   "foo"    Jan-2010     18
2        A  "test"    Feb-2010     20
3        B   "foo"    Feb-2010     20
4        A  "test"  March-2010     30
5        B   "foo"  March-2010     25

OLD(ER) VERSIONS: <0.20

You can use pd.melt to get most of the way there, and then sort:

>>> df
  location  name  Jan-2010  Feb-2010  March-2010
0        A  test        12        20          30
1        B   foo        18        20          25
>>> df2 = pd.melt(df, id_vars=["location", "name"], 
                  var_name="Date", value_name="Value")
>>> df2
  location  name        Date  Value
0        A  test    Jan-2010     12
1        B   foo    Jan-2010     18
2        A  test    Feb-2010     20
3        B   foo    Feb-2010     20
4        A  test  March-2010     30
5        B   foo  March-2010     25
>>> df2 = df2.sort(["location", "name"])
>>> df2
  location  name        Date  Value
0        A  test    Jan-2010     12
2        A  test    Feb-2010     20
4        A  test  March-2010     30
1        B   foo    Jan-2010     18
3        B   foo    Feb-2010     20
5        B   foo  March-2010     25

(Might want to throw in a .reset_index(drop=True), just to keep the output clean.)

Note: pd.DataFrame.sort has been deprecated in favour of pd.DataFrame.sort_values.

Eclipse does not have internal Subversion connectivity. After you've downloaded and unzipped Eclipse, you have to install a Subversion plug-in. Check with the other developers as to which Subversion plug-in you're using. Subclipse is one Subversion plug-in.

After you've installed the Subversion plug-in, you have to give Eclipse the repository information in the SVN Repositories view of the SVN Repositories perspective. One of the other developers should have that information.

Finally, you check out the project from Subversion, by left clicking on the Package Explorer, selecting New -> Project, and in the New Project wizard,left clicking on SVN -> Checkout projects from SVN.

Here's my Swift solution. In your subclass of UIViewController, override the navigationShouldPopOnBackButton method.

extension UIViewController {
    func navigationShouldPopOnBackButton() -> Bool {
        return true
    }
}

extension UINavigationController {

    func navigationBar(navigationBar: UINavigationBar, shouldPopItem item: UINavigationItem) -> Bool {
        if let vc = self.topViewController {
            if vc.navigationShouldPopOnBackButton() {
                self.popViewControllerAnimated(true)
            } else {
                for it in navigationBar.subviews {
                    let view = it as! UIView
                    if view.alpha < 1.0 {
                        [UIView .animateWithDuration(0.25, animations: { () -> Void in
                            view.alpha = 1.0
                        })]
                    }
                }
                return false
            }
        }
        return true
    }

}

just change your JDK I installed the JDK of SUN not Oracle and it works for me....

With some help from another person, we figured out it was an issue of ordering the source files within the HTML file. I learned that browsers accept the first usable format, and their seems to be an issue with the .m4v file, so I started with the .mp4, then .webm. Here's the order that works in Safari (even on my iPhone 5), Firefox, and Chrome:

<video width="100%" height="400" poster="assets/img/myVideo.jpg" controls="controls" preload="none">
      <!-- MP4 for Safari, IE9, iPhone, iPad, Android, and Windows Phone 7 -->
      <source type="video/mp4" src="assets/vid/PhysicsEtoys.mp4" />
      <!-- WebM/VP8 for Firefox4, Opera, and Chrome -->
      <source type="video/webm" src="assets/vid/PhysicsEtoys.webm" />
       <!-- M4V for Apple -->
      <source type="video/mp4" src="assets/vid/PhysicsEtoys.m4v" />
      <!-- Ogg/Vorbis for older Firefox and Opera versions -->
      <source type="video/ogg" src="assets/vid/PhysicsEtoys.ogv" />
      <!-- Subtitles -->
      <track kind="subtitles" src="assets/vid/subtitles.srt" srclang="en" />
      <track kind="subtitles" src="assets/vid/subtitles.vtt" srclang="en" />
      <!-- Flash fallback for non-HTML5 browsers without JavaScript -->
      <object width="100%" height="400" type="application/x-shockwave-flash" data="flashmediaelement.swf">
          <param name="movie" value="flashmediaelement.swf" />
          <param name="flashvars" value="controls=true&file=assets/vid/PhysicsEtoys.mp4" />
          <!-- Image as a last resort -->
          <img src="assets/img/myVideo.jpg" width="320" height="240" title="No video playback capabilities" />
      </object>
  </video>

Now, I'll have to re-check the encoding on the m4v file (perhaps an issue of Baseline vs Main, High, etc.).

If the targeted thread has been waiting (by calling wait(), or some other related methods that essentially do the same thing, such as sleep()), it will be interrupted, meaning that it stops waiting for what it was waiting for and receive an InterruptedException instead.

It is completely up to the thread itself (the code that called wait()) to decide what to do in this situation. It does not automatically terminate the thread.

It is sometimes used in combination with a termination flag. When interrupted, the thread could check this flag, and then shut itself down. But again, this is just a convention.

The any() function makes for readable code

> w <- c(1,2,3)
> any(w==1)
[1] TRUE

> v <- c('a','b','c')
> any(v=='b')
[1] TRUE

> any(v=='f')
[1] FALSE

1. Building off @Warewolf's answer, the next step is to create your own custom cell.

   Go to File -> New -> File -> User Interface -> Empty -> Call this nib "customNib".

2. In your customNib drag a UICollectionView Cell in. Give it reuse cell identifier @"Cell".

3. File -> New -> File -> Cocoa Touch Class -> Class named "CustomCollectionViewCell" subclass if UICollectionViewCell.

4. Go back to the custom nib, click cell and make this custom class "CustomCollectionViewCell".

5. Go to your viewDidLoad viewcontroller and instead of

   [_collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:@"cellIdentifier"];

   have

   UINib *nib = [UINib nibWithNibName:@"customNib" bundle:nil]; [_collectionView registerNib:nib forCellWithReuseIdentifier:@"Cell"];

6. Also, change (to your new cell identifier)

   UICollectionViewCell *cell=[collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];

You can do this using cross apply

SELECT c.BalanceDue AS BalanceDue
FROM Invoices
cross apply (select (InvoiceTotal - PaymentTotal - CreditTotal) as BalanceDue) as c
WHERE  c.BalanceDue  > 0;

you can also use linq and anonymous types to achieve the same result with much less code as described here.

UPDATE: blog is down, here's the content:

(..) The values shown in the table represent the length of strings instead of string values (!) It may seem strange, but that’s how binding mechanism works by default – given an object it will try to bind to the first property of that object (the first property it can find). When passed an instance the String class the property it binds to is String.Length since there’s no other property that would provide the actual string itself.

That means that to get our binding right we need a wrapper object that will expose the actual value of a string as a property:

public class StringWrapper
    {
     string stringValue;
     public string StringValue { get { return stringValue; } set { stringValue = value; } }

     public StringWrapper(string s)
     {
     StringValue = s;
     }
  }   

   List<StringWrapper> testData = new List<StringWrapper>();

   // add data to the list / convert list of strings to list of string wrappers

  Table1.SetDataBinding(testdata);

While this solution works as expected it requires quite a few lines of code (mostly to convert list of strings to the list of string wrappers).

We can improve this solution by using LINQ and anonymous types- we’ll use LINQ query to create a new list of string wrappers (string wrapper will be an anonymous type in our case).

 var values = from data in testData select new { Value = data };

 Table1.SetDataBinding(values.ToList());

The last change we’re going to make is to move the LINQ code to an extension method:

public static class StringExtensions
  {
     public static IEnumerable CreateStringWrapperForBinding(this IEnumerable<string> strings)
     {
     var values = from data in strings
     select new { Value = data };

     return values.ToList();
     }

This way we can reuse the code by calling single method on any collection of strings:

Table1.SetDataBinding(testData.CreateStringWrapperForBinding());

I've used the Zend Studio (5.5), together with Zend Platform. That gives proper debugging, breakpoints/stepping over the code etc., although at a price.

What do you mean by converting?

• casting*: (int) $float or intval($float)
• truncating: floor($float) (down) or ceil($float) (up)
• rounding: round($float) - has additional modes, see PHP_ROUND_HALF_... constants

*: casting has some chance, that float values cannot be represented in int (too big, or too small), f.ex. in your case.

PHP_INT_MAX: The largest integer supported in this build of PHP. Usually int(2147483647).

But, you could use the BCMath, or the GMP extensions for handling these large numbers. (Both are boundled, you only need to enable these extensions)

I'm not sure whether this could help, but I had a similar problem and I managed to solve it, by defining an apposite function:

def sor_dic_key(diction):
    lista = []
    diction2 = {}
    for x in diction:
        lista.append([x, diction[x]])
    lista.sort(key=lambda x: x[0])
    for l in lista:
        diction2[l[0]] = l[1]
    return diction2

This function returns another dictionary with the same keys and relative values, but sorted by its keys. Similarly, I defined a function that could sort a dictionary by its values. I just needed to use x[1] instead of x[0] in the lambda function. I find this second function mostly useless, but one never can tell!

As of .NET Core 2.2, TargetMigration seems to be gone:

get-help Update-Database

NAME
    Update-Database

SYNOPSIS
    Updates the database to a specified migration.


SYNTAX
    Update-Database [[-Migration] <String>] [-Context <String>] [-Project <String>] [-StartupProject <String>] [<CommonParameters>]


DESCRIPTION
    Updates the database to a specified migration.


RELATED LINKS
    Script-Migration
    about_EntityFrameworkCore 

REMARKS
    To see the examples, type: "get-help Update-Database -examples".
    For more information, type: "get-help Update-Database -detailed".
    For technical information, type: "get-help Update-Database -full".
    For online help, type: "get-help Update-Database -online"

So this works for me now:

Update-Database -Migration 20180906131107_xxxx_xxxx

As well as (no -Migration switch):

Update-Database 20180906131107_xxxx_xxxx

On an added note, you can no longer cleanly delete migration folders without putting your Model Snapshot out of sync. So if you learn this the hard way and wind up with an empty migration where you know there should be changes, you can run (no switches needed for the last migration):

Remove-migration

It will clean up the mess and put you back where you need to be, even though the last migration folder was deleted manually.

Simply add this in CSS,

a {
    color: inherit;
    text-decoration: none;
}

that's it, done.

try $conn = mysql_connect("localhost", "root") or $conn = mysql_connect("localhost", "root", "")

TEXT is a data-type for text based input. On the other hand, you have BLOB and CLOB which are more suitable for data storage (images, etc) due to their larger capacity limits (4GB for example).

As for the difference between BLOB and CLOB, I believe CLOB has character encoding associated with it, which implies it can be suited well for very large amounts of text.

BLOB and CLOB data can take a long time to retrieve, relative to how quick data from a TEXT field can be retrieved. So, use only what you need.

The $.getJSON() method is shorthand that does not let you specify advanced options like that. To do that, you need to use the full $.ajax() method.

Notice in the documentation at http://api.jquery.com/jQuery.getJSON/:

This is a shorthand Ajax function, which is equivalent to:

$.ajax({
  url: url,
  dataType: 'json',
  data: data,
  success: callback
});

So just use $.ajax() and provide all the extra parameters you need.

If there is a reason you can't use the simple solution provided by ennuikiller above, then you will have to use Typeglobs to manipulate file handles. This is way more work. This example copies from the file in $ARGV[0] to that in $ARGV[1]. It defaults to STDIN and STDOUT respectively if files are not specified.

use English;

my $in;
my $out;

if ($#ARGV >= 0){
    unless (open($in,  "<", $ARGV[0])){
      die "could not open $ARGV[0] for reading.";
    }
}
else {
    $in  = *STDIN;
}

if ($#ARGV >= 1){
    unless (open($out, ">", $ARGV[1])){
      die "could not open $ARGV[1] for writing.";
    }
}
else {
    $out  = *STDOUT;
}

while ($_ = <$in>){
    $out->print($_);
}

ADD supports local-only tar extraction. Besides it, COPY will use three layers, but ADD only uses one layer.

from datetime import timedelta    
datetime.datetime.now() - datetime.timedelta(0, 900)

Actually 900 is in seconds. Which is equal to 15 minutes. `15*60 = 900`

If you are facing this issue and everything looks good, try invalidate cache/restart from your IDE. This will resolve the issue in most of the cases.

You can read your BufferedInputStream like this. It will read data till it reaches end of stream which is indicated by -1.

inputS = new BufferedInputStream(inBS);
byte[] buffer = new byte[1024];    //If you handle larger data use a bigger buffer size
int read;
while((read = inputS.read(buffer)) != -1) {
    System.out.println(read);
    // Your code to handle the data
}

You can shorten this with:

Try

//re:*[. ='match']

before going for the step "compile -DIPLIB=NONE filename.cxx" take the path of VIsual Studio installation upto the vcvarsall batch file and change the configuration as shown below.

*C:\apps\MVS9\VC\vcvarsall.bat x86_amd64*

now next step should be

compile -64bit -DIPLIB=none filename.cxx

this solved the problem for me

check all the variables names in both of the combined files. Name of variables of both files to be combines should be exact same or else it will produce the above mentioned errors. I was facing the same problem as well, and after making all names same in both the file, rbind works accurately.

Thanks

Here is a complete, very simple .Net solution that works in all versions of windows. Simply paste it into a new project, run it and try CTRL-C to view how it handles it:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading;

namespace TestTrapCtrlC{
    public class Program{
        static bool exitSystem = false;

        #region Trap application termination
        [DllImport("Kernel32")]
        private static extern bool SetConsoleCtrlHandler(EventHandler handler, bool add);

        private delegate bool EventHandler(CtrlType sig);
        static EventHandler _handler;

        enum CtrlType {
         CTRL_C_EVENT = 0,
         CTRL_BREAK_EVENT = 1,
         CTRL_CLOSE_EVENT = 2,
         CTRL_LOGOFF_EVENT = 5,
         CTRL_SHUTDOWN_EVENT = 6
         }

        private static bool Handler(CtrlType sig) {
            Console.WriteLine("Exiting system due to external CTRL-C, or process kill, or shutdown");

            //do your cleanup here
            Thread.Sleep(5000); //simulate some cleanup delay

            Console.WriteLine("Cleanup complete");

            //allow main to run off
             exitSystem = true;

            //shutdown right away so there are no lingering threads
            Environment.Exit(-1);

            return true;
        }
        #endregion

        static void Main(string[] args) {
            // Some biolerplate to react to close window event, CTRL-C, kill, etc
            _handler += new EventHandler(Handler);
            SetConsoleCtrlHandler(_handler, true);

            //start your multi threaded program here
            Program p = new Program();
            p.Start();

            //hold the console so it doesn’t run off the end
            while(!exitSystem) {
                Thread.Sleep(500);
            }
        }

        public void Start() {
            // start a thread and start doing some processing
            Console.WriteLine("Thread started, processing..");
        }
    }
 }

Tried this in the console, and it works.

var aFileParts = ['<a id="a"><b id="b">hey!</b></a>'];
var oMyBlob = new Blob(aFileParts, {type : 'text/html'}); // the blob
window.open(URL.createObjectURL(oMyBlob));

I use both because sometimes they give different, useful error messages.

The Python project was able to find and fix a number of small buglets when one of the core developers first tried compiling with clang.

You can run a python script via php, and outputs on browser.

Basically you have to call the python script this way:

$command = "python /path/to/python_script.py 2>&1";
$pid = popen( $command,"r");
while( !feof( $pid ) )
{
 echo fread($pid, 256);
 flush();
 ob_flush();
 usleep(100000);
}
pclose($pid);

Note: if you run any time.sleep() in you python code, it will not outputs the results on browser.

For full codes working, visit How to execute python script from php and show output on browser

//get file input
var $el = $('input[type=file]');
//set the next siblings (the span) text to the input value 
$el.next().text( $el.val() );

What worked for me when trying to git clone inside of a Dockerfile was to fetch the SSL certificate and add it to the local certificate list:

openssl s_client -showcerts -servername git.mycompany.com -connect git.mycompany.com:443 </dev/null 2>/dev/null | sed -n -e '/BEGIN\ CERTIFICATE/,/END\ CERTIFICATE/ p'  > git-mycompany-com.pem

cat git-mycompany-com.pem | sudo tee -a /etc/ssl/certs/ca-certificates.crt

You can compose all the functions into one and call them.Libraries like Ramdajs has a function to compose multiple functions into one.

<a href="#" onclick="R.compose(fn1,fn2,fn3)()">Click me To fire some functions</a>

or you can put the composition as a seperate function in js file and call it

const newFunction = R.compose(fn1,fn2,fn3);


<a href="#" onclick="newFunction()">Click me To fire some functions</a>

Another potential way to do this for SQL Server, which has less reliance on the system tables (which are subject to change, version to version) is to use the INFORMATION_SCHEMA views:

select COLUMN_NAME, TABLE_NAME
from INFORMATION_SCHEMA.COLUMNS
where COLUMNPROPERTY(object_id(TABLE_SCHEMA+'.'+TABLE_NAME), COLUMN_NAME, 'IsIdentity') = 1
order by TABLE_NAME 

Pickling will serialize your list (convert it, and it's entries to a unique byte string), so you can save it to disk. You can also use pickle to retrieve your original list, loading from the saved file.

So, first build a list, then use pickle.dump to send it to a file...

EDIT: look at this answer. Using np.cumsum is much faster than np.convolve

A quick and dirty way to smooth data I use, based on a moving average box (by convolution):

x = np.linspace(0,2*np.pi,100)
y = np.sin(x) + np.random.random(100) * 0.8

def smooth(y, box_pts):
    box = np.ones(box_pts)/box_pts
    y_smooth = np.convolve(y, box, mode='same')
    return y_smooth

plot(x, y,'o')
plot(x, smooth(y,3), 'r-', lw=2)
plot(x, smooth(y,19), 'g-', lw=2)

I've had better results by checking the browsers readystate before continuing to the next step. This will do nothing until the browser is has a "complete" readystate

There's a setSeconds method as well:

var t = new Date();
t.setSeconds(t.getSeconds() + 10);

For a list of the other Date functions, you should check out MDN

setSeconds will correctly handle wrap-around cases:

var d;_x000D_
d = new Date('2014-01-01 10:11:55');_x000D_
alert(d.getMinutes() + ':' + d.getSeconds()); //11:55_x000D_
d.setSeconds(d.getSeconds() + 10);_x000D_
alert(d.getMinutes() + ':0' + d.getSeconds()); //12:05

Postgres hasn't implemented an equivalent to INSERT OR REPLACE. From the ON CONFLICT docs (emphasis mine):

It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.

Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE applies more generally, since it lets you set new values based on preexisting data. For example:

INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

ThreadStart delegates in C# used to start threads have return type 'void'.

If you wish to get a 'return value' from a thread, you should write to a shared location (in an appropriate thread-safe manner) and read from that when the thread has completed executing.

You can also get this error if you try to include a jar which was compiled with jdk 1.7 instead of 1.6.

In my case, I figured this out by trying to package my app with the Ant scripts provided by the SDK, instead of ADT, and I noticed these errors, which ADT did not show me:

  [dex] Pre-Dexing libjingle_peerconnection.jar -> libjingle_peerconnection-2f82c9bf868a6c58eaf2c3b2fe6a09f3.jar
   [dx]
   [dx] trouble processing:
   [dx] bad class file magic (cafebabe) or version (0033.0000)
   [dx] ...while parsing org/webrtc/StatsReport$Value.class
   [dx] ...while processing org/webrtc/StatsReport$Value.class

I recompiled my jar with jdk 1.6 and the error was fixed.

For me I had reached the maximum numbers of files a user can own

Check your numbers with quota -s and that the number under files is not too close to the quota

The Issue

The error presents itself as a message similar to this:

Cannot open database "DATABASE NAME" requested by the login. The login failed. Login failed for user XYZ.

• The error cannot usually be rectified by a simple Visual Studio or full-computer restart.
• The error can also be found as a seemingly locked database file.

The Fix

The solution is laid in the following steps. You will not lose any data in your database and you should not delete your database file!

Pre-requisite: You must have installed SQL Server Management Studio (Full or Express)

1. Open SQL Server Management Studio
2. In the "Connect to Server" window (File->Connect object explorer) enter the following:
   • Server type : Database Engine
   • Server name : (localdb)\v11.0
   • Authentication : [Whatever you used when you created your local db. Probably Windows Authentication).
3. Click "Connect"
4. Expand the "Databases" folder in the Object Explorer (View->Object Explorer, F8)
5. Find your database. It should be named as the full path to your database (.mdf) file
   • You should see it says "(Pending Recovery)" at the end of the database name or when you try to expand the database it won't be able to and may or may not give you an error message.
   • This the issue! Your database has crashed essentially..
6. Right click on the database then select "Tasks -> Detach...".
7. In the detach window, select your database in the list and check the column that says "Drop Connections"
8. Click OK.
9. You should see the database disappear from the list of databases. Your problem should now be fixed. Go and run your application that uses your localdb.
10. After running your application, your database will re-appear in the list of databases - this is correct. It should not say "Pending recovery" any more since it should be working properly.

TL;DR: The only 100% correct method is to check for @-sign somewhere in the entered email address and then posting a validation message to given email address. If they can follow validation instructions in the email message, the inputted email address is correct.

Long answer:

David Gilbertson wrote about this years ago:

There are two questions we need to ask:

1. Did the user understand that they were supposed to type an email address into this field?
2. Did the user correctly type their own email address into this field?

If you have a well laid-out form with a label that says “email”, and the user enters an ‘@’ symbol somewhere, then it’s safe to say they understood that they were supposed to be entering an email address. Easy.

Next, we want to do some validation to ascertain if they correctly entered their email address.

Not possible.

[...]

Any mistype will definitely result in an incorrect email address, but only maybe result in an invalid email address.

[...]

There is no point in trying to work out if an email address is ‘valid’. A user is far more likely to enter a wrong and valid email address than they are to enter an invalid one.

In other words, it's important to notice that any kind of string based validation can only check if the syntax is invalid. It cannot check if the user can actually see the email (e.g. because the user already lost credentials, typed address of somebody else or typed work email instead of personal email address for a given use case). How often the question you're really after is "is this email syntactically valid" instead of "can I communicate with the user using given email address"? If you validate the string more than "does it contain @", you're trying to answer the former question! Personally, I'm always interested about the latter question only.

In addition, some email addresses that may be syntactically or politically invalid, do work. For example, postmaster@ai does technically work even though TLDs should not have MX records. Also see discussion about email validation on the WHATWG mailing list (where HTML5 is designed in the first place).

What makes you say that either a singleton or a static method isn't thread-safe? Usually both should be implemented to be thread-safe.

The big difference between a singleton and a bunch of static methods is that singletons can implement interfaces (or derive from useful base classes, although that's less common, in my experience), so you can pass around the singleton as if it were "just another" implementation.

if you need the category ID, you would get it via get_query_var, that is capable of retrieving all publicly queryble variables.

$category_id = get_query_var('cat');

here is an example to get the category name

$category_name = get_query_var('category_name');

and of course the all mighty get_queried_object

$queried_object = get_queried_object();

that is returning the complete taxonomy term object (when used on a taxonomy-archive page..)

returning true or false indicates that whether execution should continue or stop right there. So just an example

<input type="button" onclick="return func();" />

Now if func() is defined like this

function func()
{
 // do something
return false;
}

the click event will never get executed. On the contrary if return true is written then the click event will always be executed.

You would probably would have to set the child div to have position: absolute.

Update your child style to

#parentDiv .childDiv
{
  height:100px;
  width:30px;
  background-color:#999;
  position:absolute;
  top:207px;
}

To perform Email Validation we have many ways,but simple & easiest way are two methods.

1- Using EditText(....).addTextChangedListener which keeps triggering on every input in an EditText box i.e email_id is invalid or valid

/**
 * Email Validation ex:- [email protected]
*/


final EditText emailValidate = (EditText)findViewById(R.id.textMessage); 

final TextView textView = (TextView)findViewById(R.id.text); 

String email = emailValidate.getText().toString().trim();

String emailPattern = "[a-zA-Z0-9._-]+@[a-z]+\\.+[a-z]+";

emailValidate .addTextChangedListener(new TextWatcher() { 
    public void afterTextChanged(Editable s) { 

    if (email.matches(emailPattern) && s.length() > 0)
        { 
            Toast.makeText(getApplicationContext(),"valid email address",Toast.LENGTH_SHORT).show();
            // or
            textView.setText("valid email");
        }
        else
        {
             Toast.makeText(getApplicationContext(),"Invalid email address",Toast.LENGTH_SHORT).show();
            //or
            textView.setText("invalid email");
        }
    } 
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    // other stuffs 
    } 
    public void onTextChanged(CharSequence s, int start, int before, int count) {
    // other stuffs 
    } 
}); 

2- Simplest method using if-else condition. Take the EditText box string using getText() and compare with pattern provided for email. If pattern doesn't match or macthes, onClick of button toast a message. It ll not trigger on every input of an character in EditText box . simple example shown below.

final EditText emailValidate = (EditText)findViewById(R.id.textMessage); 

final TextView textView = (TextView)findViewById(R.id.text); 

String email = emailValidate.getText().toString().trim();

String emailPattern = "[a-zA-Z0-9._-]+@[a-z]+\\.+[a-z]+";

// onClick of button perform this simplest code.
if (email.matches(emailPattern))
{
Toast.makeText(getApplicationContext(),"valid email address",Toast.LENGTH_SHORT).show();
}
else 
{
Toast.makeText(getApplicationContext(),"Invalid email address", Toast.LENGTH_SHORT).show();
}

The error is a stack overflow. That should ring a bell on this site, right? It occurs because a call to poruszanie results in another call to poruszanie, incrementing the recursion depth by 1. The second call results in another call to the same function. That happens over and over again, each time incrementing the recursion depth.

Now, the usable resources of a program are limited. Each function call takes a certain amount of space on top of what is called the stack. If the maximum stack height is reached, you get a stack overflow error.

You must include jQuery in the project.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

I didn't find any doc about this so I just opened a random code example from tutorialrepublic.com http://www.tutorialrepublic.com/twitter-bootstrap-tutorial/bootstrap-dropdowns.php

How to call this function? please view below code;

private List<FundraiserStudentListModel> GetStudentsFromExcel(HttpPostedFileBase file)
    {
        List<FundraiserStudentListModel> list = new List<FundraiserStudentListModel>();
        if (file != null)
        {
            try
            {
                using (ExcelPackage package = new ExcelPackage(file.InputStream))
                {
                    ExcelWorkbook workbook = package.Workbook;
                    if (workbook != null)
                    {
                        ExcelWorksheet worksheet = workbook.Worksheets.FirstOrDefault();
                        if (worksheet != null)
                        {
                            list = worksheet.ImportExcelToList<FundraiserStudentListModel>();
                        }
                    }
                }
            }
            catch (Exception err)
            {
                //save error log
            }
        }
        return list;
    }

FundraiserStudentListModel here:

 public class FundraiserStudentListModel
{
    public string Name { get; set; }
    public string Email { get; set; }
    public string Phone { get; set; }
}

Sounds correct but some issues maybe creates executing this query: I would suggest:

$this->db->where( "$accommodation BETWEEN $minvalue AND $maxvalue", NULL, FALSE );

If you're coding for the kind of clarity that would be understood by someone who is just starting out with Perl, the traditional this construct says what it means, with a high degree of clarity and legibility:

$string = join ', ', @array;
print "$string\n";

This construct is documented in perldoc -fjoin.

However, I've always liked how simple $, makes it. The special variable $" is for interpolation, and the special variable $, is for lists. Combine either one with dynamic scope-constraining 'local' to avoid having ripple effects throughout the script:

use 5.012_002;
use strict;
use warnings;

my @array = qw/ 1 2 3 4 5 /;

{
    local $" = ', ';
    print "@array\n"; # Interpolation.
}

OR with $,:

use feature q(say);
use strict;
use warnings;

my @array = qw/ 1 2 3 4 5 /;
{
    local $, = ', ';
    say @array; # List
}

The special variables $, and $" are documented in perlvar. The local keyword, and how it can be used to constrain the effects of altering a global punctuation variable's value is probably best described in perlsub.

Enjoy!

This is my idea of what you are trying to do and it works fine:

public static void main(String[] args) throws IOException{

    BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

    BufferedWriter out = new BufferedWriter(new FileWriter("c://output.txt"));
    try {
        String inputLine = null;
        do {
            inputLine=in.readLine();
            out.write(inputLine);
            out.newLine();
        } while (!inputLine.equalsIgnoreCase("eof"));
        System.out.print("Write Successful");
    } catch(IOException e1) {
        System.out.println("Error during reading/writing");
    } finally {
        out.close();
        in.close();
    }
}

Works Perfect

For anyone else that comes across this post and might find it useful... There is actually nothing wrong with my code. I made the mistake of requesting client_credentials type access code instead of password access code (#facepalms). FYI I am using urlencoded post hence the use of querystring.. So for those that may be looking for some example code.. here is my full request

Big thanks to @swapnil for trying to help me debug this.

   const data = {
      grant_type: USER_GRANT_TYPE,
      client_id: CLIENT_ID,
      client_secret: CLIENT_SECRET,
      scope: SCOPE_INT,
      username: DEMO_EMAIL,
      password: DEMO_PASSWORD
    };



  axios.post(TOKEN_URL, Querystring.stringify(data))   
   .then(response => {
      console.log(response.data);
      USER_TOKEN = response.data.access_token;
      console.log('userresponse ' + response.data.access_token); 
    })   
   .catch((error) => {
      console.log('error ' + error);   
   });



const AuthStr = 'Bearer '.concat(USER_TOKEN); 
axios.get(URL, { headers: { Authorization: AuthStr } })
 .then(response => {
     // If request is good...
     console.log(response.data);
  })
 .catch((error) => {
     console.log('error ' + error);
  });

The currently accepted answer is now out of date, at least if you are supporting iOS 7.

Here is what you should be using if you are only supporting iOS7+:

+ (UIImage *) imageWithView:(UIView *)view
{
    UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.opaque, 0.0f);
    [view drawViewHierarchyInRect:view.bounds afterScreenUpdates:NO];
    UIImage * snapshotImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return snapshotImage;
}

Swift 4:

func imageWithView(view: UIView) -> UIImage? {
    UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.isOpaque, 0.0)
    defer { UIGraphicsEndImageContext() }
    view.drawHierarchy(in: view.bounds, afterScreenUpdates: true)
    return UIGraphicsGetImageFromCurrentImageContext()
}

As per this article, you can see that the new iOS7 method drawViewHierarchyInRect:afterScreenUpdates: is many times faster than renderInContext:.

Notice: I do update this answer as I find better solutions. I also keep the old answers for future reference as long as they remain related. Latest and best answer comes first.

Better answer:

Directives in angularjs are very powerful, but it takes time to comprehend which processes lie behind them.

While creating directives, angularjs allows you to create an isolated scope with some bindings to the parent scope. These bindings are specified by the attribute you attach the element in DOM and how you define scope property in the directive definition object.

There are 3 types of binding options which you can define in scope and you write those as prefixes related attribute.

angular.module("myApp", []).directive("myDirective", function () {
    return {
        restrict: "A",
        scope: {
            text: "@myText",
            twoWayBind: "=myTwoWayBind",
            oneWayBind: "&myOneWayBind"
        }
    };
}).controller("myController", function ($scope) {
    $scope.foo = {name: "Umur"};
    $scope.bar = "qwe";
});

HTML

<div ng-controller="myController">
    <div my-directive my-text="hello {{ bar }}" my-two-way-bind="foo" my-one-way-bind="bar">
    </div>
</div>

In that case, in the scope of directive (whether it's in linking function or controller), we can access these properties like this:

/* Directive scope */

in: $scope.text
out: "hello qwe"
// this would automatically update the changes of value in digest
// this is always string as dom attributes values are always strings

in: $scope.twoWayBind
out: {name:"Umur"}
// this would automatically update the changes of value in digest
// changes in this will be reflected in parent scope

// in directive's scope
in: $scope.twoWayBind.name = "John"

//in parent scope
in: $scope.foo.name
out: "John"


in: $scope.oneWayBind() // notice the function call, this binding is read only
out: "qwe"
// any changes here will not reflect in parent, as this only a getter .

"Still OK" Answer:

Since this answer got accepted, but has some issues, I'm going to update it to a better one. Apparently, $parse is a service which does not lie in properties of the current scope, which means it only takes angular expressions and cannot reach scope. {{,}} expressions are compiled while angularjs initiating which means when we try to access them in our directives postlink method, they are already compiled. ({{1+1}} is 2 in directive already).

This is how you would want to use:

var myApp = angular.module('myApp',[]);

myApp.directive('myDirective', function ($parse) {
    return function (scope, element, attr) {
        element.val("value=" + $parse(attr.myDirective)(scope));
    };
});

function MyCtrl($scope) {
    $scope.aaa = 3432;
}?

.

<div ng-controller="MyCtrl">
    <input my-directive="123">
    <input my-directive="1+1">
    <input my-directive="'1+1'">
    <input my-directive="aaa">
</div>????????

One thing you should notice here is that, if you want set the value string, you should wrap it in quotes. (See 3rd input)

Here is the fiddle to play with: http://jsfiddle.net/neuTA/6/

Old Answer:

I'm not removing this for folks who can be misled like me, note that using $eval is perfectly fine the correct way to do it, but $parse has a different behavior, you probably won't need this to use in most of the cases.

The way to do it is, once again, using scope.$eval. Not only it compiles the angular expression, it has also access to the current scope's properties.

var myApp = angular.module('myApp',[]);

myApp.directive('myDirective', function () {
    return function (scope, element, attr) {
        element.val("value = "+ scope.$eval(attr.value));
    }
});

function MyCtrl($scope) {
   
}?

What you are missing was $eval.

http://docs.angularjs.org/api/ng.$rootScope.Scope#$eval

Executes the expression on the current scope returning the result. Any exceptions in the expression are propagated (uncaught). This is useful when evaluating angular expressions.

First of all, I think you've misunderstood what the viewport is. The viewport is the area a browser uses to render web pages, and you cannot in any way build your web sites to override this area in any way.

Secondly, it seems that the reason that your overlay-div won't cover the entire viewport is because you have to remove all margins on BODY and HTML.

Try adding this at the top of your stylesheet - it resets all margins and paddings on all elements. Makes further development easier:

* { margin: 0; padding: 0; }

Edit: I just understood your question better. Position: fixed; will probably work out for you, as Jonathan Sampson have written.

Service

• Task with no UI,but should not use for long Task. Use Thread within service for long Task
• Invoke by onStartService()
• Triggered from any Thread
• Runs On Main Thread
• May block main(UI) thread

IntentService

• Long task usually no communication with main thread if communication is needed then it is done by Handler or broadcast
• Invoke via Intent
• triggered from Main Thread (Intent is received on main Thread and worker thread is spawned)
• Runs on separate thread
• We can't run task in parallel and multiple intents are Queued on the same worker thread.

I wrote a little script based on Florian's answer that uses nano (my favorite editor):

#!/bin/sh

if [ "$#" -ne 3 ]; then
  echo "Usage: $0 hugeFilePath startLine endLine" >&2
  exit 1
fi

sed -n -e $2','$3'p' -e $3'q' $1 > hfnano_temporary_file
nano hfnano_temporary_file
(head -n `expr $2 - 1` $1; cat hfnano_temporary_file; sed -e '1,'$3'd' $1) > hfnano_temporary_file2
cat hfnano_temporary_file2 > $1
rm hfnano_temporary_file hfnano_temporary_file2

Use it like this:

sh hfnano yourHugeFile 3 8

In that example, nano will open up lines 3 through 8, you can edit them, and when you save and quit, those lines in the hugefile will automatically be overwritten with your saved lines.

/**
 * Tests image load.
 * @param {String} url
 * @returns {Promise}
 */
function testImageUrl(url) {
  return new Promise(function(resolve, reject) {
    var image = new Image();
    image.addEventListener('load', resolve);
    image.addEventListener('error', reject);
    image.src = url;
  });
}

return testImageUrl(imageUrl).then(function imageLoaded(e) {
  return imageUrl;
})
.catch(function imageFailed(e) {
  return defaultImageUrl;
});

I had the same problem, and I found the real cause.

I had written some concurrent / multi-threads code, while I added some breakpoints inside the code running in a new thread. So, when JUnit tests ran over, and stopped soon, the code will not reach and stop at the breakpoints.

For this situation, we have to click and select "Keep JUnit running after a test run when debugging" check box at "Debug Configurations..."

In Bash you can do it by enabling the extglob option, like this (replace ls with cp and add the target directory, of course)

~/foobar> shopt extglob
extglob        off
~/foobar> ls
abar  afoo  bbar  bfoo
~/foobar> ls !(b*)
-bash: !: event not found
~/foobar> shopt -s extglob  # Enables extglob
~/foobar> ls !(b*)
abar  afoo
~/foobar> ls !(a*)
bbar  bfoo
~/foobar> ls !(*foo)
abar  bbar

You can later disable extglob with

shopt -u extglob

You can use my script from CodePen by just wrapping all the content within a .levit-container DIV.

~function  () {
    function Smooth () {
        this.$container = document.querySelector('.levit-container');
        this.$placeholder = document.createElement('div');
    }

    Smooth.prototype.init = function () {
        var instance = this;

        setContainer.call(instance);
        setPlaceholder.call(instance);
        bindEvents.call(instance);
    }

    function bindEvents () {
        window.addEventListener('scroll', handleScroll.bind(this), false);
    }

    function setContainer () {
        var style = this.$container.style;

        style.position = 'fixed';
        style.width = '100%';
        style.top = '0';
        style.left = '0';
        style.transition = '0.5s ease-out';
    }

    function setPlaceholder () {
        var instance = this,
                $container = instance.$container,
                $placeholder = instance.$placeholder;

        $placeholder.setAttribute('class', 'levit-placeholder');
        $placeholder.style.height = $container.offsetHeight + 'px';
        document.body.insertBefore($placeholder, $container);
    }

    function handleScroll () {
        this.$container.style.transform = 'translateZ(0) translateY(' + (window.scrollY * (- 1)) + 'px)';
    }

    var smooth = new Smooth();
    smooth.init();
}();

You're searching for gc_maxlifetime, see http://php.net/manual/en/session.configuration.php#ini.session.gc-maxlifetime for a description.

Your session will last 1440 seconds which is 24 minutes (default).

I also wondered that long time ago. I searched a bit in my history and I think that this post: http://lists.mysql.com/internals/34919 represents the semi-official position of MySQL (before Oracle's intervention ;))

In short:

this limitation stems only from the way in which this feature is currently implemented in the server and there are no other reasons for its existence.

So their explanation is "because it is implemented like this". Doesn't sound very scientific. I guess it all comes from some old code. This is suggested in the thread above: "carry-over from when only the first timestamp field was auto-set/update".

Cheers!

Just connect the device to the PC with a USB cable, then copy the .apk file to the device. On the device, touch the APK file in the file explorer to install it.

You could also offer the .apk on your website. People can download it, then touch it to install.

F5 triggers a standard reload.

Ctrl + F5 triggers a forced reload. This causes the browser to re-download the page from the web server, ensuring that it always has the latest copy.

Unlike with F5, a forced reload does not display a cached copy of the page.

The update() triggers an update of the chart. chart.update( )

.update(config)

Triggers an update of the chart. This can be safely called after updating the data object. This will update all scales, legends, and then re-render the chart. A config object can be provided with additional configuration for the update process.

update() can be safely called after updating values of one or more existing points within the the data object, rendering the changes in one animated render loop.

// update the first dataset's value of 'March' to be 50
myBarChart.data.datasets[0].bars[2].value = 50;

// animate update of 'March' from 90 to 50.
myBarChart.update();

You need to trigger form validation before checking if it is valid. Field validation runs after you enter data in each field. Form validation is triggered by the submit event but at the document level. So your event handler is being triggered before jquery validates the whole form. But fret not, there's a simple solution to all of this.

You should validate the form:

if ($(this).validate().form()) {
  // do ajax stuff
}

https://jqueryvalidation.org/Validator.form/#validator-form()

One way to do it:

in .git/config fetch for the remote repo should be set to fetch any branch:

   [remote "origin"]
            fetch = +refs/heads/*:refs/remotes/origin/*

to fetch the remote branch:

git fetch origin branch-name

to create a local branch 'branch-name' set up to track remote branch 'branch-name' from origin.

git checkout -b branch-name origin/branch-name

to list all branches

git branch -a

To wrap text in the label control, change the the template of label as follows:

<Style x:Key="ErrorBoxStyle" TargetType="{x:Type Label}">
    <Setter Property="BorderBrush" Value="#FFF08A73"/>
    <Setter Property="BorderThickness" Value="1"/>
    <Setter Property="Foreground" Value="Red"/>
    <Setter Property="Background" Value="#FFFFE3DF"/>
    <Setter Property="FontWeight" Value="Bold"/>
    <Setter Property="Padding" Value="5"/>
    <Setter Property="HorizontalContentAlignment" Value="Left"/>
    <Setter Property="VerticalContentAlignment" Value="Top"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Label}">
                <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="true" CornerRadius="5" HorizontalAlignment="Stretch">
                     
                    <TextBlock TextWrapping="Wrap" Text="{TemplateBinding Content}"/>
                </Border>
                    
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

I stopped writing this myself for laravel in favor of the Laracasts package that handles it all for you. It is really easy to use and keeps your code clean. There is even a laracast that covers how to use it. All you have to do:

Pull in the package through Composer.

"require": {
  "laracasts/flash": "~1.0"
}

Include the service provider within app/config/app.php.

'providers' => [
  'Laracasts\Flash\FlashServiceProvider'
];

Add a facade alias to this same file at the bottom:

'aliases' => [
  'Flash' => 'Laracasts\Flash\Flash'
];

Pull the HTML into the view:

@include('flash::message') 

There is a close button on the right of the message. This relies on jQuery so make sure that is added before your bootstrap.

optional changes:

If you aren't using bootstrap or want to skip the include of the flash message and write the code yourself:

@if (Session::has('flash_notification.message'))
  <div class="{{ Session::get('flash_notification.level') }}">
    {{ Session::get('flash_notification.message') }}
  </div>
@endif

If you would like to view the HTML pulled in by @include('flash::message'), you can find it in vendor/laracasts/flash/src/views/message.blade.php.

If you need to modify the partials do:

php artisan view:publish laracasts/flash

The two package views will now be located in the `app/views/packages/laracasts/flash/' directory.

If the variant is empty then an error will be thrown. The bullet-proof code is the following:

Public Function GetLength(a As Variant) As Integer
   If IsEmpty(a) Then
      GetLength = 0
   Else
      GetLength = UBound(a) - LBound(a) + 1
   End If
End Function

You need the ip of the other pc and do:

scp user@ip_of_remote_pc:/home/user/stuff.php /Users/djorge/Desktop

it will ask you for 'user's password on the other pc.

When you import a module (or a member of it) for the first time, the code inside the module is executed sequentially like any other code; e.g., it is not treated any differently that the body of a function. An import is just a command like any other (assignment, a function call, def, class). Assuming your imports occur at the top of the script, then here's what's happening:

• When you try to import World from world, the world script gets executed.
• The world script imports Field, which causes the entities.field script to get executed.
• This process continues until you reach the entities.post script because you tried to import Post
• The entities.post script causes physics module to be executed because it tries to import PostBody
• Finally, physics tries to import Post from entities.post
• I'm not sure whether the entities.post module exists in memory yet, but it really doesn't matter. Either the module is not in memory, or the module doesn't yet have a Post member because it hasn't finished executing to define Post
• Either way, an error occurs because Post is not there to be imported

So no, it's not "working further up in the call stack". This is a stack trace of where the error occurred, which means it errored out trying to import Post in that class. You shouldn't use circular imports. At best, it has negligible benefit (typically, no benefit), and it causes problems like this. It burdens any developer maintaining it, forcing them to walk on egg shells to avoid breaking it. Refactor your module organization.

The find command will take long time, the fastest way to search for file is using locate command, which looks for file names (and path) in a indexed database (updated by command updatedb).

The result will appear immediately with a simple command:

locate {file-name-or-path}

If the command is not found, you need to install mlocate package and run updatedb command first to prepare the search database for the first time.

Use md5 library: https://github.com/blueimp/JavaScript-MD5

The shortest way:

md5(Math.random())

If you want to limit the size to 5:

md5(Math.random()).substr(0, 5)

This is most likely a NT file permissions problem. IUSR_ needs to have file system permissions to read whatever file you're requesting (like /inetpub/wwwroot/index.htm).

If you still have trouble, check the IIS logs, typically at \windows\system32\logfiles\W3SVC*.

Actually, Ruby does have an in-place editing feature. Like Perl, you can say

ruby -pi.bak -e "gsub(/oldtext/, 'newtext')" *.txt

This will apply the code in double-quotes to all files in the current directory whose names end with ".txt". Backup copies of edited files will be created with a ".bak" extension ("foobar.txt.bak" I think).

NOTE: this does not appear to work for multiline searches. For those, you have to do it the other less pretty way, with a wrapper script around the regex.

ES6:

let csv = test_array.map(row=>row.join(',')).join('\n') 
//test_array being your 2D array

I just figured out a way to fix the alignment issue. Changing the width of div containing the static header will fix its alignment. The optimal width I found is 98%. Please refer to the code.

The auto generated div:

<div class="dataTables_scrollHead" style="overflow: hidden; position: relative; border: 0px none; width: 100%;">

Width here is 100%, change it to 98% on initializing and reloading the data table.

jQuery('#dashboard').dataTable({
    "sEcho": "1",

    "aaSorting": [[aasortvalue, 'desc']],
    "bServerSide": true,
    "sAjaxSource": "NF.do?method=loadData&Table=dashboardReport",
    "bProcessing": true,
    "sPaginationType": "full_numbers",
    "sDom": "lrtip", // Add 'f' to add back in filtering
    "bJQueryUI": false,
    "sScrollX": "100%",
    "sScrollY": "450px",
    "iDisplayLength": '<%=recordCount%>',
    "bScrollCollapse": true,
    "bScrollAutoCss": true,
    "fnInitComplete": function () {
        jQuery('.dataTables_scrollHead').css('width', '98%'); //changing the width
    },
    "fnDrawCallback": function () {
        jQuery('.dataTables_scrollHead').css('width', '98%');//changing the width
    }
});

Do this

 let currentdate = new Date();
 let last3months = new Date(currentdate.setMonth(currentdate.getMonth()-3));

Javascript's setMonth method also takes care of the year. For instance, the above code will return 2020-01-29 if currentDate is set as new Date("2020-01-29")

go to C:xampp\apache\conf\extra\httpd-ssl.conf
Find the line where it says Listen 443, change it to Listen 4330 and restart your computer

Be warned, the majority of the mathematically calculated examples have a hard limit of 2038-01-18 dates and will not work with fictional dates.

As there was a lack of DateTime and DateInterval based examples, I wanted to provide a multi-purpose function that satisfies the OP's need and others wanting compound elapsed periods, such as 1 month 2 days ago. Along with a bunch of other use cases, such as a limit to display the date instead of the elapsed time, or to filter out portions of the elapsed time result.

Additionally the majority of the examples assume elapsed is from the current time, where the below function allows for it to be overridden with the desired end date.

/**
 * multi-purpose function to calculate the time elapsed between $start and optional $end
 * @param string|null $start the date string to start calculation
 * @param string|null $end the date string to end calculation
 * @param string $suffix the suffix string to include in the calculated string
 * @param string $format the format of the resulting date if limit is reached or no periods were found
 * @param string $separator the separator between periods to use when filter is not true
 * @param null|string $limit date string to stop calculations on and display the date if reached - ex: 1 month
 * @param bool|array $filter false to display all periods, true to display first period matching the minimum, or array of periods to display ['year', 'month']
 * @param int $minimum the minimum value needed to include a period
 * @return string
 */
function elapsedTimeString($start, $end = null, $limit = null, $filter = true, $suffix = 'ago', $format = 'Y-m-d', $separator = ' ', $minimum = 1)
{
    $dates = (object) array(
        'start' => new DateTime($start ? : 'now'),
        'end' => new DateTime($end ? : 'now'),
        'intervals' => array('y' => 'year', 'm' => 'month', 'd' => 'day', 'h' => 'hour', 'i' => 'minute', 's' => 'second'),
        'periods' => array()
    );
    $elapsed = (object) array(
        'interval' => $dates->start->diff($dates->end),
        'unknown' => 'unknown'
    );
    if ($elapsed->interval->invert === 1) {
        return trim('0 seconds ' . $suffix);
    }
    if (false === empty($limit)) {
        $dates->limit = new DateTime($limit);
        if (date_create()->add($elapsed->interval) > $dates->limit) {
            return $dates->start->format($format) ? : $elapsed->unknown;
        }
    }
    if (true === is_array($filter)) {
        $dates->intervals = array_intersect($dates->intervals, $filter);
        $filter = false;
    }
    foreach ($dates->intervals as $period => $name) {
        $value = $elapsed->interval->$period;
        if ($value >= $minimum) {
            $dates->periods[] = vsprintf('%1$s %2$s%3$s', array($value, $name, ($value !== 1 ? 's' : '')));
            if (true === $filter) {
                break;
            }
        }
    }
    if (false === empty($dates->periods)) {
        return trim(vsprintf('%1$s %2$s', array(implode($separator, $dates->periods), $suffix)));
    }

    return $dates->start->format($format) ? : $elapsed->unknown;
}

One thing to note - the retrieved intervals for the supplied filter values do not carry over to the next period. The filter merely displays the resulting value of the supplied periods and does not recalculate the periods to display only the desired filter total.

Usage

For the OP's need of displaying the highest period (as of 2015-02-24).

echo elapsedTimeString('2010-04-26');
/** 4 years ago */

To display compound periods and supply a custom end date (note the lack of time supplied and fictional dates).

echo elapsedTimeString('1920-01-01', '2500-02-24', null, false);
/** 580 years 1 month 23 days ago */

To display the result of filtered periods (ordering of array doesn't matter).

echo elapsedTimeString('2010-05-26', '2012-02-24', null, ['month', 'year']);
/** 1 year 8 months ago */

To display the start date in the supplied format (default Y-m-d) if the limit is reached.

echo elapsedTimeString('2010-05-26', '2012-02-24', '1 year');
/** 2010-05-26 */

There are bunch of other use cases. It can also easily be adapted to accept unix timestamps and/or DateInterval objects for the start, end, or limit arguments.

We should first know what is Pull to refresh layout in android . we can call pull to refresh in android as swipe-to-refresh. when you swipe screen from top to bottom it will do some action based on setOnRefreshListener.

Here's tutorial that demonstrate about how to implement android pull to refresh. I hope this helps.

In an ultimate act of boredom, I actually wrote a few versions of these loops and compiled it with GCC on my mac mini.

the while(1){} and for(;;) {} produced same assembly results while the do{} while(1); produced similar but a different assembly code

heres the one for while/for loop

    .section    __TEXT,__text,regular,pure_instructions
    .globl  _main
    .align  4, 0x90

    .cfi_startproc

More generally, generating a random integer with fixed length can be done using Math.pow:

var randomFixedInteger = function (length) {
    return Math.floor(Math.pow(10, length-1) + Math.random() * (Math.pow(10, length) - Math.pow(10, length-1) - 1));
}

To answer the question: randomFixedInteger(6);

You can also declare a constant and use it each time. neat and avoids confusion:

const string myStrQuote = "\"";

Ok, for me that work with this...

var e2key = function(e) {

    };
    return event2key[(e.which || e.keyCode)];
};

var page5Key = function(e, customKey) {
    if (e) e.preventDefault();
    switch(e2key(customKey || e)) {
        case 'left': /*...*/ break;
        case 'right': /*...*/ break;
    }
};

$(document).bind('keyup', page5Key);

$(document).trigger('keyup', [{preventDefault:function(){},keyCode:37}]);

The collection.count is deprecated, and will be removed in a future version. Use collection.countDocuments or collection.estimatedDocumentCount instead.

userModel.countDocuments(query).exec((err, count) => {
    if (err) {
        res.send(err);
        return;
    }

    res.json({ count: count });
});

    }
    .scrollable-content::-webkit-scrollbar-thumb {
      background:rgba(255,0,0,0.1) !important; // manage scrollbar thumb background color here
    }

If you want them to be displayed side by side, why is sideContent the child of mainContent? make them siblings then use:

float:left; display:inline; width: 49%;

on both of them.

#mainContent, #sideContent {float:left; display:inline; width: 49%;}

I had the issue where it wouldn't find the PayPal assembly and it was because I had named my solution PayPal. I'm sure this won't be the answer for anyone but thought I'd share it anyway: C# ASP.NET MVC PayPal not finding assembly

Cygwin has issue recognizing space in between the PC name. So to solve this, you have to use "\" after the first word then include the space, then the last name.

such as ".../my\ dir/"

$ cd /cygdrive/c/Users/my\ dir/Documents

Another interesting and simple way to do it, is to put the directory in quotation marks ("")

e.g run it as follows:

$ cd c:
$ cd Users
$ cd "my dir"
$ cd Documents

Hope it works?

As Johannes Gorset pointed out, the post by Thomas Ptacek from Matasano Security explains why simple, general-purpose hashing functions such as MD5, SHA1, SHA256 and SHA512 are poor password hashing choices.

Why? They are too fast--you can calculate at least 1,000,000 MD5 hashes a second per core with a modern computer, so brute force is feasible against most passwords people use. And that's much less than a GPU-based cracking server cluster!

Salting without key stretching only means that you cannot precompute the rainbow table, you need to build it ad hoc for that specific salt. But it won't really make things that much harder.

User @Will says:

Everyone is talking about this like they can be hacked over the internet. As already stated, limiting attempts makes it impossible to crack a password over the Internet and has nothing to do with the hash.

They don't need to. Apparently, in the case of LinkedIn they used the common SQL injection vulnerability to get the login DB table and cracked millions of passwords offline.

Then he goes back to the offline attack scenario:

The security really comes into play when the entire database is compromised and a hacker can then perform 100 million password attempts per second against the md5 hash. SHA512 is about 10,000 times slower.

No, SHA512 is not 10000 times slower than MD5--it only takes about twice as much. Crypt/SHA512, on the other hand, is a very different beast that, like its BCrypt counterpart, performs key stretching, producing a very different hash with a random salt built-in and will take anything between 500 and 999999 times as much to compute (stretching is tunable).

SHA512 => aaf4c61ddcc5e8a2dabede0f3b482cd9aea9434d
Crypt/SHA512 => $6$rounds=5000$usesomesillystri$D4IrlXatmP7rx3P3InaxBeoomnAihCKRVQP22JZ6EY47Wc6BkroIuUUBOov1i.S5KPgErtP/EN5mcO.ChWQW21

So the choice for PHP is either Crypt/Blowfish (BCrypt), Crypt/SHA256 or Crypt/SHA512. Or at least Crypt/MD5 (PHK). See www.php.net/manual/en/function.crypt.php

The following script works for me for multiple values of $COLUMNS. I wonder if you are not setting COLUMNS prior to this call?

#!/bin/bash
COLUMNS=30
svn diff $@ --diff-cmd /usr/bin/diff -x "-y -w -p -W $COLUMNS"

Can you echo $COLUMNS inside your script to see if it set correctly?

Here's a version, again using the cross product logic, written in Clojure.

(defn is-left? [line point]
  (let [[[x1 y1] [x2 y2]] (sort line)
        [x-pt y-pt] point]
    (> (* (- x2 x1) (- y-pt y1)) (* (- y2 y1) (- x-pt x1)))))

Example usage:

(is-left? [[-3 -1] [3 1]] [0 10])
true

Which is to say that the point (0, 10) is to the left of the line determined by (-3, -1) and (3, 1).

NOTE: This implementation solves a problem that none of the others (so far) does! Order matters when giving the points that determine the line. I.e., it's a "directed line", in a certain sense. So with the above code, this invocation also produces the result of true:

(is-left? [[3 1] [-3 -1]] [0 10])
true

That's because of this snippet of code:

(sort line)

Finally, as with the other cross product based solutions, this solution returns a boolean, and does not give a third result for collinearity. But it will give a result that makes sense, e.g.:

(is-left? [[1 1] [3 1]] [10 1])
false

Not really.

Depending on what you actually need, one possibility may be to set o as the prototype of a new object.

var o = {};
(function(x){
    var obj = Object.create( x );
    obj.foo = 'foo';
    obj.bar = 'bar';
})(o);

alert( o.foo ); // undefined

So any properties you add to obj will be not be added to o. Any properties added to obj with the same property name as a property in o will shadow the o property.

Of course, any properties added to o will be available from obj if they're not shadowed, and all objects that have o in the prototype chain will see the same updates to o.

Also, if obj has a property that references another object, like an Array, you'll need to be sure to shadow that object before adding members to the object, otherwise, those members will be added to obj, and will be shared among all objects that have obj in the prototype chain.

var o = {
    baz: []
};
(function(x){
    var obj = Object.create( x );

    obj.baz.push( 'new value' );

})(o);

alert( o.baz[0] );  // 'new_value'

Here you can see that because you didn't shadow the Array at baz on o with a baz property on obj, the o.baz Array gets modified.

So instead, you'd need to shadow it first:

var o = {
    baz: []
};
(function(x){
    var obj = Object.create( x );

    obj.baz = [];
    obj.baz.push( 'new value' );

})(o);

alert( o.baz[0] );  // undefined

Here is a simple AFNetworking POST I'm using. To get up and running after reading the AFNetworking doc, wkiki, ref, etc, I learned a lot by following http://nsscreencast.com/episodes/6-afnetworking and understanding the associated code sample on github.

 // Add this to the class you're working with - (id)init {}
    _netInst = [MyApiClient sharedAFNetworkInstance];

  // build the dictionary that AFNetworkng converts to a json object on the next line
  //  params = {"user":{"email":emailAddress,"password":password}};
  NSDictionary *parameters =[NSDictionary dictionaryWithObjectsAndKeys:
                             userName, @"email", password, @"password", nil];
  NSDictionary *params =[NSDictionary dictionaryWithObjectsAndKeys:
                         parameters, @"user", nil];

   [_netInst postPath: @"users/login.json" parameters:params
      success:^(AFHTTPRequestOperation *operation, id jsonResponse) {
        NSLog (@"SUCCESS");

        // jsonResponse = {"user":{"accessId":1234,"securityKey":"abc123"}};
        _accessId = [jsonResponse valueForKeyPath:@"user.accessid"];
        _securityKey = [jsonResponse valueForKeyPath:@"user.securitykey"];

        return SUCCESS;
      }
      failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"FAILED");

        // handle failure

        return error;
      }
   ];  

May it's late for the answer. But will be helpful for anyone.

In My case want to call activity from Fragment and setResult back from the fragment.

I have used getContext of Fragment Like.

startActivityForResult(new Intent(getContext(), NextActivity.class), 111);

And Set Result from Fragment

getActivity().setResult(Activity.RESULT_OK);
                    getActivity().finish();

Now Getting Result to Fragment with

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == Activity.RESULT_OK && requestCode == 111) {

    }
}

Use a wild card selector * for this purpose.

#div * { /* Narrowing, to specific elements, like  input, textarea is PREFFERED */
 -webkit-user-select: none;  
  -moz-user-select: none;    
  -ms-user-select: none;      
  user-select: none;
}

Now, every element inside a div with id div will have no selection.

A simple solution is to use Microsoft ASP.NET Web API 2.2 Client from NuGet.

Then you can simply do this and it'll serialize the object to JSON and set the Content-Type header to application/json; charset=utf-8:

var data = new
{
    name = "Foo",
    category = "article"
};

var client = new HttpClient();
client.BaseAddress = new Uri(baseUri);
client.DefaultRequestHeaders.Add("token", token);
var response = await client.PostAsJsonAsync("", data);

For posterity, I think this is quicker:

a = np.array([np.array(list()) for _ in y])

You might even be able to pass in a generator (i.e. [] -> ()), in which case the inner list is never fully stored in memory.

Responding to comment below:

>>> import numpy as np
>>> y = range(10)
>>> a = np.array([np.array(list) for _ in y])
>>> a
array([array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object)], dtype=object)

It's a matter of convention, really. string just looks more like C/C++ style. The general convention is to use whatever shortcuts your chosen language has provided (int/Int for Int32). This goes for "object" and decimal as well.

Theoretically this could help to port code into some future 64-bit standard in which "int" might mean Int64, but that's not the point, and I would expect any upgrade wizard to change any int references to Int32 anyway just to be safe.

Depends on what you run in that thread. If that's your code, then you can implement a stop condition (see other answers).

However, if what you want is to run someone else's code, then you should fork and start a process. Like this:

import multiprocessing
proc = multiprocessing.Process(target=your_proc_function, args=())
proc.start()

now, whenever you want to stop that process, send it a SIGTERM like this:

proc.terminate()
proc.join()

And it's not slow: fractions of a second. Enjoy :)

To extend onto above answers, You can actually add more than one package in your EnableJPARepositories tag, so that you won't run into "Object not mapped" error after only specifying the repository package.

@SpringBootApplication
@EnableJpaRepositories(basePackages = {"com.test.model", "com.test.repository"})
public class SpringBootApplication{

}

In script is usefull something like this:

if [ ! -d /etc/nginx ]; then ln -s /usr/local/nginx/conf/ /etc/nginx > /dev/null 2>&1; fi

it prevents before re-create "bad" looped symlink after re-run script

This approach has the advantage of not needing to loop over all the elements (at least not explicitly). But since array_to_string_internal() in array.c still loops over array elements and concatenates them into a string, it's probably not more efficient than the looping solutions proposed, but it's more readable.

if [[ " ${array[@]} " =~ " ${value} " ]]; then
    # whatever you want to do when array contains value
fi

if [[ ! " ${array[@]} " =~ " ${value} " ]]; then
    # whatever you want to do when array doesn't contain value
fi

Note that in cases where the value you are searching for is one of the words in an array element with spaces, it will give false positives. For example

array=("Jack Brown")
value="Jack"

The regex will see "Jack" as being in the array even though it isn't. So you'll have to change IFS and the separator characters on your regex if you want still to use this solution, like this

IFS=$'\t'
array=("Jack Brown\tJack Smith")
unset IFS
value="Jack"

if [[ "\t${array[@]}\t" =~ "\t${value}\t" ]]; then
    echo "true"
else
    echo "false"
fi

This will print "false".

Obviously this can also be used as a test statement, allowing it to be expressed as a one-liner

[[ " ${array[@]} " =~ " ${value} " ]] && echo "true" || echo "false"

There are two things to consider: users can modify forms, and you need to secure against Cross Site Scripting (XSS).

XSS

XSS is when a user enters HTML into their input. For example, what if a user submitted this value?:

" /><script type="text/javascript" src="http://example.com/malice.js"></script><input value="

This would be written into your form like so:

<input type="hidden" name="prova[]" value="" /><script type="text/javascript" src="http://example.com/malice.js"></script><input value=""/>

The best way to protect against this is to use htmlspecialchars() to secure your input. This encodes characters such as < into <. For example:

<input type="hidden" name="prova[]" value="<?php echo htmlspecialchars($array); ?>"/>

You can read more about XSS here: https://www.owasp.org/index.php/XSS

Form Modification

If I were on your site, I could use Chrome's developer tools or Firebug to modify the HTML of your page. Depending on what your form does, this could be used maliciously.

I could, for example, add extra values to your array, or values that don't belong in the array. If this were a file system manager, then I could add files that don't exist or files that contain sensitive information (e.g.: replace myfile.jpg with ../index.php or ../db-connect.php).

In short, you always need to check your inputs later to make sure that they make sense, and only use safe inputs in forms. A File ID (a number) is safe, because you can check to see if the number exists, then extract the filename from a database (this assumes that your database contains validated input). A File Name isn't safe, for the reasons described above. You must either re-validate the filename or else I could change it to anything.

If I understand correctly what you're trying to do, you need to play with the buttons image edge inset. Something like:

myLikesButton.imageEdgeInsets = UIEdgeInsets(top: 30, left: 30, bottom: 30, right: 30)

I asked a similar question related to performance of the LinkedList collection, and discovered Steven Cleary's C# implement of Deque was a solution. Unlike the Queue collection, Deque allows moving items on/off front and back. It is similar to linked list, but with improved performance.

Following steps shows total information about how to get file, file with extension, file without extension. This technique is very helpful for me. Hope it will be helpful to you too.

  $url = 'https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_120x44dp.png';
        $file = file_get_contents($url); // to get file
        $name = basename($url); // to get file name
        $ext = pathinfo($url, PATHINFO_EXTENSION); // to get extension
        $name2 =pathinfo($url, PATHINFO_FILENAME); //file name without extension

This topic, especially the answer of Xotic750 was very helpful to me. I wanted to generate a json variable to pass it to a php script using ajax. My values were stored into two arrays, and i wanted them in json format. This is a generic example:

valArray1 = [121, 324, 42, 31];
valArray2 = [232, 131, 443];
myJson = {objArray1: {}, objArray2: {}};
for (var k = 1; k < valArray1.length; k++) {
    var objName = 'obj' + k;
    var objValue = valArray1[k];
    myJson.objArray1[objName] = objValue;
}
for (var k = 1; k < valArray2.length; k++) {
    var objName = 'obj' + k;
    var objValue = valArray2[k];
    myJson.objArray2[objName] = objValue;
}
console.log(JSON.stringify(myJson));

The result in the console Log should be something like this:

{
   "objArray1": {
        "obj1": 121,
        "obj2": 324,
        "obj3": 42,
        "obj4": 31
   },
   "objArray2": {
        "obj1": 232,
        "obj2": 131,
        "obj3": 443
  }
}

The documentation says:

class (Optional) String
One or more CSS classes to remove from the elements, these are separated by spaces.

Example:

Remove the class 'blue' and 'under' from the matched elements.

$("p:odd").removeClass("blue under");

Assuming you're running on a Windows machine...

1. Hit the F12 key
2. Select the Scripts, or Sources, tab in the developer tools
3. Click the little folder icon in the top level
4. Select your JavaScript file
5. Add a breakpoint by clicking on the line number on the left (adds a little blue marker)
6. Execute your JavaScript

Then during execution debugging you can do a handful of stepping motions...

• F8 Continue: Will continue until the next breakpoint
• F10 Step over: Steps over next function call (won't enter the library)
• F11 Step into: Steps into the next function call (will enter the library)
• Shift + F11 Step out: Steps out of the current function

Update

After reading your updated post; to debug your code I would recommend temporarily using the jQuery Development Source Code. Although this doesn't directly solve your problem, it will allow you to debug more easily. For what you're trying to achieve I believe you'll need to step-in to the library, so hopefully the production code should help you decipher what's happening.

I did this with std::function and std::bind..

I wrote this EventManager class that stores a vector of handlers in an unordered_map that maps event types (which are just const unsigned int, I have a big namespace-scoped enum of them) to a vector of handlers for that event type.

In my EventManagerTests class, I set up an event handler, like this:

auto delegate = std::bind(&EventManagerTests::OnKeyDown, this, std::placeholders::_1);
event_manager.AddEventListener(kEventKeyDown, delegate);

Here's the AddEventListener function:

std::vector<EventHandler>::iterator EventManager::AddEventListener(EventType _event_type, EventHandler _handler)
{
    if (listeners_.count(_event_type) == 0) 
    {
        listeners_.emplace(_event_type, new std::vector<EventHandler>());
    }
    std::vector<EventHandler>::iterator it = listeners_[_event_type]->end();
    listeners_[_event_type]->push_back(_handler);       
    return it;
}

Here's the EventHandler type definition:

typedef std::function<void(Event *)> EventHandler;

Then back in EventManagerTests::RaiseEvent, I do this:

Engine::KeyDownEvent event(39);
event_manager.RaiseEvent(1, (Engine::Event*) & event);

Here's the code for EventManager::RaiseEvent:

void EventManager::RaiseEvent(EventType _event_type, Event * _event)
{
    if (listeners_.count(_event_type) > 0)
    {
        std::vector<EventHandler> * vec = listeners_[_event_type];
        std::for_each(
            begin(*vec), 
            end(*vec), 
            [_event](EventHandler handler) mutable 
            {
                (handler)(_event);
            }
        );
    }
}

This works. I get the call in EventManagerTests::OnKeyDown. I have to delete the vectors come clean up time, but once I do that there are no leaks. Raising an event takes about 5 microseconds on my computer, which is circa 2008. Not exactly super fast, but. Fair enough as long as I know that and I don't use it in ultra hot code.

I'd like to speed it up by rolling my own std::function and std::bind, and maybe using an array of arrays rather than an unordered_map of vectors, but I haven't quite figured out how to store a member function pointer and call it from code that knows nothing about the class being called. Eyelash's answer looks Very Interesting..

An alternative way can be this: - recommended as using just one expression -

case when address.country <> '' then address.country
else 'United States'
end as country

Note: Result of checking null by <> operator will return false.
And as documented: NULLIF is equivalent to a searched CASE expression
and COALESCE expression is a syntactic shortcut for the CASE expression.
So, combination of those are using two time of case expression.

Why not just use $('#msform').hide()? Behind the scene jQuery's hide and show just set display: none or display: block.

hide() will not change the style if already hidden.

based on the comment below, you are removing all style with removeAttr("style"), in which case call hide() immediately after that.

e.g.

$("#msform").removeAttr("style").hide();

The reverse of this is of course show() as in

$("#msform").show();

Or, more interestingly, toggle(), which effective flips between hide() and show() based on the current state.

Criteria API

Criteria API is better suited for dynamically generated queries. So, if you want to add WHERE clause filters, JOIN clauses, or vary the ORDER BY clause or the projection columns, then the Criteria API can help you generate the query dynamically in a way that also prevents SQL Injection attacks.

On the other hand, Criteria queries are less expressive and can even lead to very complicated and inefficient SQL queries.

JPQL and HQL

JPQL is the JPA standard entity query language while HQL extends JPQL and adds some Hibernate-specific features.

JPQL and HQL are very expressive and resemble SQL. Unlike Criteria API, JPQL and HQL make it easy to predict the underlying SQL query that's generated by the JPA provider. It's also much easier to review one's HQL queries than Criteria ones.

It's worth noting that selecting entities with JPQL or Criteria API makes sense if you need to modify them. Otherwise, a DTO projection is a much better choice.

Conclusion

If you don't need to vary the entity query structure, then use JPQL or HQL. If you need to change the filtering or sorting criteria or change the projection, then use Criteria API.

However, just because you are using JPA or Hibernate, it doesn't mean you should not use native SQL. SQL queries are very useful and JPQL and Criteria API are not a replacement for SQL.

This is probably the longest process to make a singleton in typescript, but in larger applications is the one that has worked better for me.

First you need a Singleton class in, let's say, "./utils/Singleton.ts":

module utils {
    export class Singleton {
        private _initialized: boolean;

        private _setSingleton(): void {
            if (this._initialized) throw Error('Singleton is already initialized.');
            this._initialized = true;
        }

        get setSingleton() { return this._setSingleton; }
    }
}

Now imagine you need a Router singleton "./navigation/Router.ts":

/// <reference path="../utils/Singleton.ts" />

module navigation {
    class RouterClass extends utils.Singleton {
        // NOTICE RouterClass extends from utils.Singleton
        // and that it isn't exportable.

        private _init(): void {
            // This method will be your "construtor" now,
            // to avoid double initialization, don't forget
            // the parent class setSingleton method!.
            this.setSingleton();

            // Initialization stuff.
        }

        // Expose _init method.
        get init { return this.init; }
    }

    // THIS IS IT!! Export a new RouterClass, that no
    // one can instantiate ever again!.
    export var Router: RouterClass = new RouterClass();
}

Nice!, now initialize or import wherever you need:

/// <reference path="./navigation/Router.ts" />

import router = navigation.Router;

router.init();
router.init(); // Throws error!.

The nice thing about doing singletons this way is that you still use all the beauty of typescript classes, it gives you nice intellisense, the singleton logic keeps someway separated and it's easy to remove if needed.
