I think the correct method should be : - (void)addTarget:(id)target action:(SEL)action forControlEvents:(UIControlEvents)controlEvents

UIControl Reference

Where do you get your method from?

I see that your selector has an argument, that argument will be filled by the runtime system. It will send you back the button through that argument.

Your method should look like:

- (void)buttonPressed:(id)BUTTON_HERE { }

According to the MediaPlayer life cycle, which you can view in the Android API guide, I think that you have to call reset() instead of stop(), and after that prepare again the media player (use only one) to play the sound from the beginning. Take also into account that the sound may have finished. So I would also recommend to implement setOnCompletionListener() to make sure that if you try to play again the sound it doesn't fail.

Looking at your code, you need to set the frame of the movie player controller's view, and also add the movie player controller's view to your view. Also, don't forget to add MediaPlayer.framework to your target.

Here's some sample code:

#import <MediaPlayer/MediaPlayer.h>

@interface ViewController () {
    MPMoviePlayerController *moviePlayerController;
}

@property (weak, nonatomic) IBOutlet UIView *movieView; // this should point to a view where the movie will play

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    // Instantiate a movie player controller and add it to your view
    NSString *moviePath = [[NSBundle mainBundle] pathForResource:@"foo" ofType:@"mov"];
    NSURL *movieURL = [NSURL fileURLWithPath:moviePath];    
    moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
    [moviePlayerController.view setFrame:self.movieView.bounds];  // player's frame must match parent's
    [self.movieView addSubview:moviePlayerController.view];

    // Configure the movie player controller
    moviePlayerController.controlStyle = MPMovieControlStyleNone;        
    [moviePlayerController prepareToPlay];
}

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    // Start the movie
    [moviePlayerController play];
}

@end

Escape the quotes with backslashes:

printf("She said \"time flies like an arrow, but fruit flies like a banana\"."); 

There are special escape characters that you can use in string literals, and these are denoted with a leading backslash.

Our array of objects

var someData = [
   {firstName: "Max", lastName: "Mustermann", age: 40},
   {firstName: "Hagbard", lastName: "Celine", age: 44},
   {firstName: "Karl", lastName: "Koch", age: 42},
];

with for...in

var employees = {
    accounting: []
};

for(var i in someData) {    

    var item = someData[i];   

    employees.accounting.push({ 
        "firstName" : item.firstName,
        "lastName"  : item.lastName,
        "age"       : item.age 
    });
}

or with Array.prototype.map(), which is much cleaner:

var employees = {
    accounting: []
};

someData.map(function(item) {        
   employees.accounting.push({ 
        "firstName" : item.firstName,
        "lastName"  : item.lastName,
        "age"       : item.age 
    });
}

If you have the aws command line interface installed on your system you can make use of pythons subprocess library. For example:

import subprocess
def copy_file_to_s3(source: str, target: str, bucket: str):
   subprocess.run(["aws", "s3" , "cp", source, f"s3://{bucket}/{target}"])

Similarly you can use that logics for all sort of AWS client operations like downloading or listing files etc. It is also possible to get return values. This way there is no need to import boto3. I guess its use is not intended that way but in practice I find it quite convenient that way. This way you also get the status of the upload displayed in your console - for example:

Completed 3.5 GiB/3.5 GiB (242.8 MiB/s) with 1 file(s) remaining

To modify the method to your wishes I recommend having a look into the subprocess reference as well as to the AWS Cli reference.

Note: This is a copy of my answer to a similar question.

Use Dictionary - it uses hashtable but is typesafe.

Also, your Java code for

int a = map.get(key);
//continue with your logic

will be best coded in C# this way:

int a;
if(dict.TryGetValue(key, out a)){
//continue with your logic
}

This way, you can scope the need of variable "a" inside a block and it is still accessible outside the block if you need it later.

Always use tax_query to get posts/products from a particular category or any other taxonomy. You can also get the products using ID/slug of particular taxonomy...

$the_query = new WP_Query( array(
    'post_type' => 'product',
    'tax_query' => array(
        array (
            'taxonomy' => 'product_cat',
            'field' => 'slug',
            'terms' => 'accessories',
        )
    ),
) );

while ( $the_query->have_posts() ) :
    $the_query->the_post();
    the_title(); echo "<br>";
endwhile;


wp_reset_postdata();

This method opens a file in the private data area of the application. You cannot open any files in subdirectories in this area or from entirely other areas using this method. So use the constructor of the FileInputStream directly to pass the path with a directory in it.

Just learning this myself. I will answer the second question:

2. How to use these files? Currently I am using webpack-dev-server to run the application.

Instead of using webpack-dev-server, you can just run an "express". use npm install "express" and create a server.js in the project's root dir, something like this:

var path = require("path");
var express = require("express");

var DIST_DIR = path.join(__dirname, "build");
var PORT = 3000;
var app = express();

//Serving the files on the dist folder
app.use(express.static(DIST_DIR));

//Send index.html when the user access the web
app.get("*", function (req, res) {
  res.sendFile(path.join(DIST_DIR, "index.html"));
});

app.listen(PORT);

Then, in the package.json, add a script:

"start": "node server.js"

Finally, run the app: npm run start to start the server

A detailed example can be seen at: https://alejandronapoles.com/2016/03/12/the-simplest-webpack-and-express-setup/ (the example code is not compatible with the latest packages, but it will work with small tweaks)

So, we have a situation when we need to statically get class object or a class full/simple name without an explicit usage of MyClass.class syntax.

It can be really handy in some cases, e.g. logger instance for the kotlin upper-level functions (in this case kotlin creates a static Java class not accessible from the kotlin code).

We have a few different variants for getting this info:

1. new Object(){}.getClass().getEnclosingClass();
   noted by Tom Hawtin - tackline

2. getClassContext()[0].getName(); from the SecurityManager
   noted by Christoffer

3. new Throwable().getStackTrace()[0].getClassName();
   by count ludwig

4. Thread.currentThread().getStackTrace()[1].getClassName();
   from Keksi

5. and finally awesome
   MethodHandles.lookup().lookupClass();
   from Rein

I've prepared a jmh benchmark for all variants and results are:

# Run complete. Total time: 00:04:18

StaticClassLookup.Throwable_stackTrace_0_className             avgt   30  10221.209 ± 176.847  ns/op

Conclusions

1. Best variant to use, rather clean and monstrously fast.
   Available only since Java 7 and Android API 26!

 MethodHandles.lookup().lookupClass();

2. In case you need this functionality for Android or Java 6, you can use the second best variant. It's rather fast too, but creates an anonymous class in each place of usage :(

 new Object(){}.getClass().getEnclosingClass();

3. If you need it in many places and don't want your bytecode to bloat due to tons of anonymous classes – SecurityManager is your friend (third best option).

   But you can't just call getClassContext() – it's protected in the SecurityManager class. You will need some helper class like this:

 // Helper class
 public final class CallerClassGetter extends SecurityManager
 {
    private static final CallerClassGetter INSTANCE = new CallerClassGetter();
    private CallerClassGetter() {}

    public static Class<?> getCallerClass() {
        return INSTANCE.getClassContext()[1];
    }
 }

 // Usage example:
 class FooBar
 {
    static final Logger LOGGER = LoggerFactory.getLogger(CallerClassGetter.getCallerClass())
 }

4. You probably don't ever need to use last two variants based on the getStackTrace() from exception or the Thread.currentThread(). Very inefficient and can return only the class name as a String, not the Class<*> instance.

P.S.

If you want to create a logger instance for static kotlin utils (like me :), you can use this helper:

import org.slf4j.Logger
import org.slf4j.LoggerFactory

// Should be inlined to get an actual class instead of the one where this helper declared
// Will work only since Java 7 and Android API 26!
@Suppress("NOTHING_TO_INLINE")
inline fun loggerFactoryStatic(): Logger
    = LoggerFactory.getLogger(MethodHandles.lookup().lookupClass())

Usage example:

private val LOGGER = loggerFactoryStatic()

/**
 * Returns a pseudo-random, uniformly distributed value between the
 * given least value (inclusive) and bound (exclusive).
 *
 * @param min the least value returned
 * @param max the upper bound (exclusive)
 *
 * @return the next value
 * @throws IllegalArgumentException if least greater than or equal to bound
 * @see java.util.concurrent.ThreadLocalRandom.nextDouble(double, double)
 */
fun Random.nextDouble(min: Double = .0, max: Double = 1.0): Double {
    if (min >= max) {
        if (min == max) return max
        LOGGER.warn("nextDouble: min $min > max $max")
        return min
    }
    return nextDouble() * (max - min) + min
}

I'm using autolayout and none of the answers worked for me. Here is my solution that finally worked:

@property (nonatomic, assign) BOOL shouldScrollToLastRow;


- (void)viewDidLoad {
    [super viewDidLoad];

    _shouldScrollToLastRow = YES;
}


- (void)viewDidLayoutSubviews {
    [super viewDidLayoutSubviews];

    // Scroll table view to the last row
    if (_shouldScrollToLastRow)
    {
        _shouldScrollToLastRow = NO;
        [self.tableView setContentOffset:CGPointMake(0, CGFLOAT_MAX)];
    }
}

Similar to hute37's answer but using the purrr package. I think this tidyverse approach is simpler than the answer proposed by AbiK.

library(purrr)
map_dbl(df, ~sum(is.na(.)))

Note: the tilde (~) creates an anonymous function. And the '.' refers to the input for the anonymous function, in this case the data.frame df.

The difference is that the post-increment operator i++ returns i as it was before incrementing, and the pre-increment operator ++i returns i as it is after incrementing. If you're asking about a typical for loop:

for (i = 0; i < 10; i++)

or

for (i = 0; i < 10; ++i)

They're exactly the same, since you're not using i++ or ++i as a part of a larger expression.

I was facing the same issue as below.

npm ERR! errno -4058 npm ERR! syscall open npm ERR! enoent ENOENT: no such file or directory, open 'D:\SVenu\FullStackDevelopment\Angular\Angular2_Splitter_CodeSkeleton\CodeSke leton\run\package.json' npm ERR! enoent This is related to npm not being able to find a file. npm ERR! enoent

The problem I made was, I was running the command npm build run instead of running npm run build.

Few characters like alphabets i-o couldn't be converted into respective ASCII chars . like in string '6631653064316f30723161' corresponds to fedora . but it gives fedra

Just modify hex_to_int() function a little and it will work for all characters. modified function is

int hex_to_int(char c)
{
    if (c >= 97)
        c = c - 32;
    int first = c / 16 - 3;
    int second = c % 16;
    int result = first * 10 + second;
    if (result > 9) result--;
    return result;
}

Now try it will work for all characters.

jQuery("input.first").click(function(){
   jQuery("input.second").trigger("click");
   return false;
});

You need to call p.Start() to actually run the process after you set the StartInfo. As it is, your function is probably hanging on the WaitForExit() call because the process was never actually started.

What output (exactly) does dir myfile.txt give in the current directory? What happens if you set the delimiters?

FOR /f "tokens=1,2* delims= " %%a in ('dir myfile.txt^|find /i " myfile.txt"') DO SET fileDate=%%a 

(note the space after delims=)
(to make life easier, you can do this from the command line by replacing %%a with %a)

Can't upvote so I'll repost @jfs comment cause I think it should be more visible.

@AnneTheAgile: shell=True is not required. Moreover you should not use it unless it is necessary (see @ valid's comment). You should pass each command-line argument as a separate list item instead e.g., use ['command', 'arg 1', 'arg 2'] instead of "command 'arg 1' 'arg 2'". – jfs Mar 3 '15 at 10:02

TypeScript 0.9+ has a specification for enums:

enum AnimationType {
    BOUNCE,
    DROP,
}

The final comma is optional.

In my case I had to run php artisan optimize:clear in order to make everything to work again.

Chrome, Firefox, IE10 and Safari support the html5 placeholder attribute

<input type="text" placeholder="First Name:" />

In order to get a more cross browser solution you'll need to use some javascript, there are plenty of pre-made solutions out there, though I don't know any off the top of my head.

Try this values_list('column_name', flat=True).

answers = Answer.objects.filter(id__in=[answer.id for answer in answer_set.answers.all()]).values_list('column_name', flat=True)

It will return you a list with specified column values

For the yAxis you'll also need:

gridLineColor: 'transparent',

You have to cd to your master directory and then rails s command will work without problems.

But do not forget bundle-install command when you didn't do it before.

my 2¢ quick global fix:

// drop down in responsive table

(function () {
  $('.table-responsive').on('shown.bs.dropdown', function (e) {
    var $table = $(this),
        $menu = $(e.target).find('.dropdown-menu'),
        tableOffsetHeight = $table.offset().top + $table.height(),
        menuOffsetHeight = $menu.offset().top + $menu.outerHeight(true);

    if (menuOffsetHeight > tableOffsetHeight)
      $table.css("padding-bottom", menuOffsetHeight - tableOffsetHeight);
  });

  $('.table-responsive').on('hide.bs.dropdown', function () {
    $(this).css("padding-bottom", 0);
  })
})();

Explications: When a dropdown-menu inside a '.table-responsive' is shown, it calculate the height of the table and expand it (with padding) to match the height required to display the menu. The menu can be any size.

In my case, this is not the table that has the '.table-responsive' class, it's a wrapping div:

<div class="table-responsive" style="overflow:auto;">
    <table class="table table-hover table-bordered table-condensed server-sort">

So the $table var in the script is actually a div! (just to be clear... or not) :)

Note: I wrap it in a function so my IDE can collapse function ;) but it's not mandatory!

Redis is an in memory data store, that can persist it's state to disk (to enable recovery after restart). However, being an in-memory data store means the size of the data store (on a single node) cannot exceed the total memory space on the system (physical RAM + swap space). In reality, it will be much less that this, as Redis is sharing that space with many other processes on the system, and if it exhausts the system memory space it will likely be killed off by the operating system.

Mongo is a disk based data store, that is most efficient when it's working set fits within physical RAM (like all software). Being a disk based data means there are no intrinsic limits on the size of a Mongo database, however configuration options, available disk space, and other concerns may mean that databases sizes over a certain limit may become impractical or inefficient.

Both Redis and Mongo can be clustered for high availability, backup and to increase the overall size of the datastore.

In Bash (and ksh, zsh, dash, etc.), you can use parameter expansion with % which will remove characters from the end of the string or # which will remove characters from the beginning of the string. If you use a single one of those characters, the smallest matching string will be removed. If you double the character, the longest will be removed.

$ a='hello:world'

$ b=${a%:*}
$ echo "$b"
hello

$ a='hello:world:of:tomorrow'

$ echo "${a%:*}"
hello:world:of

$ echo "${a%%:*}"
hello

$ echo "${a#*:}"
world:of:tomorrow

$ echo "${a##*:}"

The biggest fix that was needed is when Unmarshalling an array, that property needs to be an array/slice in the struct as well.

For example:

{ "things": ["a", "b", "c"] }

Would Unmarshal into a:

type Item struct {
    Things []string
}

And not into:

type Item struct {
    Things string
}

The other thing to watch out for when Unmarshaling is that the types line up exactly. It will fail when Unmarshalling a JSON string representation of a number into an int or float field -- "1" needs to Unmarshal into a string, not into an int like we saw with ShippingAdditionalCost int

There is also the new Android Scripting Environment (ASE/SL4A) project. It looks awesome, and it has some integration with native Android components.

Note: no longer under "active development", but some forks may be.

If rm cannot remove a symlink, perhaps you need to look at the permissions on the directory that contains the symlink. To remove directory entries, you need write permission on the containing directory.

Technically, i don't think that there is a difference, because properties are just wrappers around fields created by the user or automatically created by the compiler.The purpose of properties is to enforce encapsuation and to offer a lightweight method-like feature. It's just a bad practice to declare fields as public, but it does not have any issues.

For me, this is the best autofit and autoresize for table and its columns (use css !important ... only if you can't without)

.myclass table {
    table-layout: auto !important;
}

.myclass th, .myclass td, .myclass thead th, .myclass tbody td, .myclass tfoot td, .myclass tfoot th {
    width: auto !important;
}

Don't specify css width for table or for table columns. If table content is larger it will go over screen size to.

DECLARE @baseTicks AS BIGINT;
SET @baseTicks = 599266080000000000; --# ticks up to 1900-01-01

DECLARE @ticksPerDay AS BIGINT;
SET @ticksPerDay = 864000000000;

SELECT CAST(@baseTicks + (@ticksPerDay * CAST(GETDATE() AS FLOAT)) AS BIGINT) AS currentDateTicks;

there are gotchas with this - but ultimately the simplest way will be to use

string s = [yourlongstring];
string[] values = s.Split(',');

If the number of commas and entries isn't important, and you want to get rid of 'empty' values then you can use

string[] values = s.Split(",".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);

One thing, though - this will keep any whitespace before and after your strings. You could use a bit of Linq magic to solve that:

string[] values = s.Split(',').Select(sValue => sValue.Trim()).ToArray();

That's if you're using .Net 3.5 and you have the using System.Linq declaration at the top of your source file.

$observe() is a method on the Attributes object, and as such, it can only be used to observe/watch the value change of a DOM attribute. It is only used/called inside directives. Use $observe when you need to observe/watch a DOM attribute that contains interpolation (i.e., {{}}'s).
E.g., attr1="Name: {{name}}", then in a directive: attrs.$observe('attr1', ...).
(If you try scope.$watch(attrs.attr1, ...) it won't work because of the {{}}s -- you'll get undefined.) Use $watch for everything else.

$watch() is more complicated. It can observe/watch an "expression", where the expression can be either a function or a string. If the expression is a string, it is $parse'd (i.e., evaluated as an Angular expression) into a function. (It is this function that is called every digest cycle.) The string expression can not contain {{}}'s. $watch is a method on the Scope object, so it can be used/called wherever you have access to a scope object, hence in

• a controller -- any controller -- one created via ng-view, ng-controller, or a directive controller
• a linking function in a directive, since this has access to a scope as well

Because strings are evaluated as Angular expressions, $watch is often used when you want to observe/watch a model/scope property. E.g., attr1="myModel.some_prop", then in a controller or link function: scope.$watch('myModel.some_prop', ...) or scope.$watch(attrs.attr1, ...) (or scope.$watch(attrs['attr1'], ...)).
(If you try attrs.$observe('attr1') you'll get the string myModel.some_prop, which is probably not what you want.)

As discussed in comments on @PrimosK's answer, all $observes and $watches are checked every digest cycle.

Directives with isolate scopes are more complicated. If the '@' syntax is used, you can $observe or $watch a DOM attribute that contains interpolation (i.e., {{}}'s). (The reason it works with $watch is because the '@' syntax does the interpolation for us, hence $watch sees a string without {{}}'s.) To make it easier to remember which to use when, I suggest using $observe for this case also.

To help test all of this, I wrote a Plunker that defines two directives. One (d1) does not create a new scope, the other (d2) creates an isolate scope. Each directive has the same six attributes. Each attribute is both $observe'd and $watch'ed.

<div d1 attr1="{{prop1}}-test" attr2="prop2" attr3="33" attr4="'a_string'"
        attr5="a_string" attr6="{{1+aNumber}}"></div>

Look at the console log to see the differences between $observe and $watch in the linking function. Then click the link and see which $observes and $watches are triggered by the property changes made by the click handler.

Notice that when the link function runs, any attributes that contain {{}}'s are not evaluated yet (so if you try to examine the attributes, you'll get undefined). The only way to see the interpolated values is to use $observe (or $watch if using an isolate scope with '@'). Therefore, getting the values of these attributes is an asynchronous operation. (And this is why we need the $observe and $watch functions.)

Sometimes you don't need $observe or $watch. E.g., if your attribute contains a number or a boolean (not a string), just evaluate it once: attr1="22", then in, say, your linking function: var count = scope.$eval(attrs.attr1). If it is just a constant string – attr1="my string" – then just use attrs.attr1 in your directive (no need for $eval()).

See also Vojta's google group post about $watch expressions.

I've had this issue on a lot of mobile views I've recently built.

My solution is still a pure CSS Fallback

http://css-tricks.com/perfect-full-page-background-image/ as three great methods, the latter two are fall backs for when CSS3's cover doesn't work.

HTML

<img src="images/bg.jpg" id="bg" alt="">

CSS

#bg {
  position: fixed; 
  top: 0; 
  left: 0; 

  /* Preserve aspect ratio */
  min-width: 100%;
  min-height: 100%;
}

It could be some un-initialized function pointer, in particular if you have corrupted memory (then the bogus vtable of C++ bad pointers to invalid objects might give that).

BTW gdb watchpoints & tracepoints, and also valgrind might be useful (if available) to debug such issues. Or some address sanitizer.

You are not supposed to assign it to any variable, when you append something in the list, it updates automatically. use only:-

last_list.append(p.last)

if you assign this to a variable "last_list" again, it will no more be a list (will become a none type variable since you haven't declared the type for that) and append will become invalid in the next run.

I did not like any of the answers above and came up with the below

function isString(variable) { 
    return typeof (variable) === 'string'; 
}

function replaceLastOccurenceInString(input, find, replaceWith) {
    if (!isString(input) || !isString(find) || !isString(replaceWith)) {
        // returns input on invalid arguments
        return input;
    }

    const lastIndex = input.lastIndexOf(find);
    if (lastIndex < 0) {
        return input;
    }

    return input.substr(0, lastIndex) + replaceWith + input.substr(lastIndex + find.length);
}

Usage:

const input = 'ten eleven twelve thirteen fourteen fifteen sixteen seventeen eighteen nineteen twenty';
const find = 'teen';
const replaceWith = 'teenhundred';

const output = replaceLastOccurrenceInString(input, find, replaceWith);
console.log(output);

// output: ten eleven twelve thirteen fourteen fifteen sixteen seventeen eighteen nineteenhundred twenty

Hope that helps!

data: vcnt(4).

clear vcnt.

LOOP at itab WHERE value = '1'.
  add 1 to vcnt.
ENDLOOP.

The answer will be 3. (vcnt = 3).

Much like leonardocsouza, I had the same problem. To clarify a bit, this is what my folder structure looked like when I ran node server.js

node_modules/
app/
  index.html
  server.js

After printing out the __dirname path, I realized that the __dirname path was where my server was running (app/).

So, the answer to your question is this:

If your server.js file is in the same folder as the files you are trying to render, then

app.use( express.static( path.join( application_root, 'site') ) );

should actually be

app.use(express.static(application_root));

The only time you would want to use the original syntax that you had would be if you had a folder tree like so:

app/
  index.html
node_modules
server.js

where index.html is in the app/ directory, whereas server.js is in the root directory (i.e. the same level as the app/ directory).

Side note: Intead of calling the path utility, you can use the syntax application_root + 'site' to join a path.

Overall, your code could look like:

// Module dependencies.
var application_root = __dirname,
express = require( 'express' ), //Web framework
mongoose = require( 'mongoose' ); //MongoDB integration

//Create server
var app = express();

// Configure server
app.configure( function() {

    //Don't change anything here...

    //Where to serve static content
    app.use( express.static( application_root ) );

    //Nothing changes here either...
});

//Start server --- No changes made here
var port = 5000;
app.listen( port, function() {
    console.log( 'Express server listening on port %d in %s mode', port, app.settings.env );
});

All the approaches described did not work for me because I was adding the click event with on() to the document where the element was created at run-time:

$(document).on("click", ".button", function() {
    doSomething();
});

My workaround:

As I could not unbind the ".button" class I just assigned another class to the button that had the same CSS styles. By doing so the live/on-event-handler ignored the click finally:

// prevent another click on the button by assigning another class
$(".button").attr("class","buttonOff");

Hope that helps.

Some background: I went looking for exactly this question because I had to do something to retrieve content, but all I had available was an old version of python with inadequate SSL support. If you're on an older MacBook, you know what I'm talking about. In any case, curl runs fine from a shell (I suspect it has modern SSL support linked in) so sometimes you want to do this without using requests or urllib2.

You can use the subprocess module to execute curl and get at the retrieved content:

import subprocess

// 'response' contains a []byte with the retrieved content.
// use '-s' to keep curl quiet while it does its job, but
// it's useful to omit that while you're still writing code
// so you know if curl is working
response = subprocess.check_output(['curl', '-s', baseURL % page_num])

Python 3's subprocess module also contains .run() with a number of useful options. I'll leave it to someone who is actually running python 3 to provide that answer.

I did use following solution to this:

findAllByStartDateLessThanEqualAndEndDateGreaterThanEqual(OffsetDateTime endDate, OffsetDateTime startDate);

For me when I run git clone, Git will store the cloned package in the directory that I am running the command from.

- I use windows.

for example :

C:\Users\user>git clone https://github.com/broosaction/aria

will create a folder:

 C:\Users\user\aria

You can try using the simple NSArray in syntax for iterating over the array in swift which makes for shorter code. The following is working for me:

class ModelAttachment {
    var id: String?
    var url: String?
    var thumb: String?
}

var modelAttachementObj = ModelAttachment()
modelAttachementObj.id = "1"
modelAttachementObj.url = "http://www.google.com"
modelAttachementObj.thumb = "thumb"

var imgs: Array<ModelAttachment> = [modelAttachementObj]

for img in imgs  {
    let url = img.url
    NSLog(url!)
}

See docs here

I had same problem as yours, but my concern was list view. When i try to scroll list view fixed header also scroll little bit. Problem was list view height smaller than viewport (browser) height. You just need to reduce your viewport height lower than content tag (list view within content tag) height. Here is my meta tag;

<meta name="viewport" content="width=device-width,height=90%,  user-scalable = no"> 

Hope this will help.Thnks.

What worked for me:

worksheet.Cells[0, 0].Style.WrapText = true;
worksheet.Cells[0, 0].Value = yourStringValue.Replace("\\r\\n", "\r\n");

My issue was that the \r\n came escaped.

• Does not matter for inner joins

• Matters for outer joins

  a. WHERE clause: After joining. Records will be filtered after join has taken place.

  b. ON clause - Before joining. Records (from right table) will be filtered before joining. This may end up as null in the result (since OUTER join).

Example: Consider the below tables:

    1. documents:
     | id    | name        |
     --------|-------------|
     | 1     | Document1   |
     | 2     | Document2   |
     | 3     | Document3   |
     | 4     | Document4   |
     | 5     | Document5   |


    2. downloads:
     | id   | document_id   | username |
     |------|---------------|----------|
     | 1    | 1             | sandeep  |
     | 2    | 1             | simi     |
     | 3    | 2             | sandeep  |
     | 4    | 2             | reya     |
     | 5    | 3             | simi     |

a) Inside WHERE clause:

  SELECT documents.name, downloads.id
    FROM documents
    LEFT OUTER JOIN downloads
      ON documents.id = downloads.document_id
    WHERE username = 'sandeep'

 For above query the intermediate join table will look like this.

    | id(from documents) | name         | id (from downloads) | document_id | username |
    |--------------------|--------------|---------------------|-------------|----------|
    | 1                  | Document1    | 1                   | 1           | sandeep  |
    | 1                  | Document1    | 2                   | 1           | simi     |
    | 2                  | Document2    | 3                   | 2           | sandeep  |
    | 2                  | Document2    | 4                   | 2           | reya     |
    | 3                  | Document3    | 5                   | 3           | simi     |
    | 4                  | Document4    | NULL                | NULL        | NULL     |
    | 5                  | Document5    | NULL                | NULL        | NULL     |

  After applying the `WHERE` clause and selecting the listed attributes, the result will be: 

   | name         | id |
   |--------------|----|
   | Document1    | 1  |
   | Document2    | 3  | 

b) Inside JOIN clause

  SELECT documents.name, downloads.id
  FROM documents
    LEFT OUTER JOIN downloads
      ON documents.id = downloads.document_id
        AND username = 'sandeep'

For above query the intermediate join table will look like this.

    | id(from documents) | name         | id (from downloads) | document_id | username |
    |--------------------|--------------|---------------------|-------------|----------|
    | 1                  | Document1    | 1                   | 1           | sandeep  |
    | 2                  | Document2    | 3                   | 2           | sandeep  |
    | 3                  | Document3    | NULL                | NULL        | NULL     |
    | 4                  | Document4    | NULL                | NULL        | NULL     |
    | 5                  | Document5    | NULL                | NULL        | NULL     |

Notice how the rows in `documents` that did not match both the conditions are populated with `NULL` values.

After Selecting the listed attributes, the result will be: 

   | name       | id   |
   |------------|------|
   |  Document1 | 1    |
   |  Document2 | 3    | 
   |  Document3 | NULL |
   |  Document4 | NULL | 
   |  Document5 | NULL | 

Another way that I found useful to use a small Expect script from a Bash script is as follows.

...
Bash script start
Bash commands
...
expect - <<EOF
spawn your-command-here
expect "some-pattern"
send "some-command"
...
...
EOF
...
More Bash commands
...

This works because ...If the string "-" is supplied as a filename, standard input is read instead...

The Python 2 documentation, 7.6. Function definitions gives you a couple of ways to detect whether a caller supplied an optional parameter.

First, you can use special formal parameter syntax *. If the function definition has a formal parameter preceded by a single *, then Python populates that parameter with any positional parameters that aren't matched by preceding formal parameters (as a tuple). If the function definition has a formal parameter preceded by **, then Python populates that parameter with any keyword parameters that aren't matched by preceding formal parameters (as a dict). The function's implementation can check the contents of these parameters for any "optional parameters" of the sort you want.

For instance, here's a function opt_fun which takes two positional parameters x1 and x2, and looks for another keyword parameter named "optional".

>>> def opt_fun(x1, x2, *positional_parameters, **keyword_parameters):
...     if ('optional' in keyword_parameters):
...         print 'optional parameter found, it is ', keyword_parameters['optional']
...     else:
...         print 'no optional parameter, sorry'
... 
>>> opt_fun(1, 2)
no optional parameter, sorry
>>> opt_fun(1,2, optional="yes")
optional parameter found, it is  yes
>>> opt_fun(1,2, another="yes")
no optional parameter, sorry

Second, you can supply a default parameter value of some value like None which a caller would never use. If the parameter has this default value, you know the caller did not specify the parameter. If the parameter has a non-default value, you know it came from the caller.

The Windows "AT" command is very similar to cron. It is available through the command line.

The old thread with many answers. but for me, these commands solved the problem.

regsvr32.exe /u "C:\Program Files (x86)\Common Files\microsoft shared\MSI Tools\mergemod.dll"

regsvr32.exe "C:\Program Files (x86)\Common Files\microsoft shared\MSI Tools\mergemod.dll"

if you want progress download try this:

var fs = require('fs');
var request = require('request');
var progress = require('request-progress');

module.exports = function (uri, path, onProgress, onResponse, onError, onEnd) {
    progress(request(uri))
    .on('progress', onProgress)
    .on('response', onResponse)
    .on('error', onError)
    .on('end', onEnd)
    .pipe(fs.createWriteStream(path))
};

how to use:

  var download = require('../lib/download');
  download("https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_150x54dp.png", "~/download/logo.png", function (state) {
            console.log("progress", state);
        }, function (response) {
            console.log("status code", response.statusCode);
        }, function (error) {
            console.log("error", error);
        }, function () {
            console.log("done");
        });

note: you should install both request & request-progress modules using:

npm install request request-progress --save

Introduction

Whenever an UICommand component (<h:commandXxx>, <p:commandXxx>, etc) fails to invoke the associated action method, or an UIInput component (<h:inputXxx>, <p:inputXxxx>, etc) fails to process the submitted values and/or update the model values, and you aren't seeing any googlable exceptions and/or warnings in the server log, also not when you configure an ajax exception handler as per Exception handling in JSF ajax requests, nor when you set below context parameter in web.xml,

<context-param>
    <param-name>javax.faces.PROJECT_STAGE</param-name>
    <param-value>Development</param-value>
</context-param>

and you are also not seeing any googlable errors and/or warnings in browser's JavaScript console (press F12 in Chrome/Firefox23+/IE9+ to open the web developer toolset and then open the Console tab), then work through below list of possible causes.

Possible causes

1. UICommand and UIInput components must be placed inside an UIForm component, e.g. <h:form> (and thus not plain HTML <form>), otherwise nothing can be sent to the server. UICommand components must also not have type="button" attribute, otherwise it will be a dead button which is only useful for JavaScript onclick. See also How to send form input values and invoke a method in JSF bean and <h:commandButton> does not initiate a postback.

2. You cannot nest multiple UIForm components in each other. This is illegal in HTML. The browser behavior is unspecified. Watch out with include files! You can use UIForm components in parallel, but they won't process each other during submit. You should also watch out with "God Form" antipattern; make sure that you don't unintentionally process/validate all other (invisible) inputs in the very same form (e.g. having a hidden dialog with required inputs in the very same form). See also How to use <h:form> in JSF page? Single form? Multiple forms? Nested forms?.

3. No UIInput value validation/conversion error should have occurred. You can use <h:messages> to show any messages which are not shown by any input-specific <h:message> components. Don't forget to include the id of <h:messages> in the <f:ajax render>, if any, so that it will be updated as well on ajax requests. See also h:messages does not display messages when p:commandButton is pressed.

4. If UICommand or UIInput components are placed inside an iterating component like <h:dataTable>, <ui:repeat>, etc, then you need to ensure that exactly the same value of the iterating component is been preserved during the apply request values phase of the form submit request. JSF will reiterate over it to find the clicked link/button and submitted input values. Putting the bean in the view scope and/or making sure that you load the data model in @PostConstruct of the bean (and thus not in a getter method!) should fix it. See also How and when should I load the model from database for h:dataTable.

5. If UICommand or UIInput components are included by a dynamic source such as <ui:include src="#{bean.include}">, then you need to ensure that exactly the same #{bean.include} value is preserved during the view build time of the form submit request. JSF will reexecute it during building the component tree. Putting the bean in the view scope and/or making sure that you load the data model in @PostConstruct of the bean (and thus not in a getter method!) should fix it. See also How to ajax-refresh dynamic include content by navigation menu? (JSF SPA).

6. The rendered attribute of the component and all of its parents and the test attribute of any parent <c:if>/<c:when> should not evaluate to false during the apply request values phase of the form submit request. JSF will recheck it as part of safeguard against tampered/hacked requests. Storing the variables responsible for the condition in a @ViewScoped bean or making sure that you're properly preinitializing the condition in @PostConstruct of a @RequestScoped bean should fix it. The same applies to the disabled and readonly attributes of the component, which should not evaluate to true during apply request values phase. See also JSF CommandButton action not invoked, Form submit in conditionally rendered component is not processed, h:commandButton is not working once I wrap it in a <h:panelGroup rendered> and Force JSF to process, validate and update readonly/disabled input components anyway

7. The onclick attribute of the UICommand component and the onsubmit attribute of the UIForm component should not return false or cause a JavaScript error. There should in case of <h:commandLink> or <f:ajax> also be no JS errors visible in the browser's JS console. Usually googling the exact error message will already give you the answer. See also Manually adding / loading jQuery with PrimeFaces results in Uncaught TypeErrors.

8. If you're using Ajax via JSF 2.x <f:ajax> or e.g. PrimeFaces <p:commandXxx>, make sure that you have a <h:head> in the master template instead of the <head>. Otherwise JSF won't be able to auto-include the necessary JavaScript files which contains the Ajax functions. This would result in a JavaScript error like "mojarra is not defined" or "PrimeFaces is not defined" in browser's JS console. See also h:commandLink actionlistener is not invoked when used with f:ajax and ui:repeat.

9. If you're using Ajax, and the submitted values end up being null, then make sure that the UIInput and UICommand components of interest are covered by the <f:ajax execute> or e.g. <p:commandXxx process>, otherwise they won't be executed/processed. See also Submitted form values not updated in model when adding <f:ajax> to <h:commandButton> and Understanding PrimeFaces process/update and JSF f:ajax execute/render attributes.

10. If the submitted values still end up being null, and you're using CDI to manage beans, then make sure that you import the scope annotation from the correct package, else CDI will default to @Dependent which effectively recreates the bean on every single evaluation of the EL expression. See also @SessionScoped bean looses scope and gets recreated all the time, fields become null and What is the default Managed Bean Scope in a JSF 2 application?

11. If a parent of the <h:form> with the UICommand button is beforehand been rendered/updated by an ajax request coming from another form in the same page, then the first action will always fail in JSF 2.2 or older. The second and subsequent actions will work. This is caused by a bug in view state handling which is reported as JSF spec issue 790 and currently fixed in JSF 2.3. For older JSF versions, you need to explicitly specify the ID of the <h:form> in the render of the <f:ajax>. See also h:commandButton/h:commandLink does not work on first click, works only on second click.

12. If the <h:form> has enctype="multipart/form-data" set in order to support file uploading, then you need to make sure that you're using at least JSF 2.2, or that the servlet filter who is responsible for parsing multipart/form-data requests is properly configured, otherwise the FacesServlet will end up getting no request parameters at all and thus not be able to apply the request values. How to configure such a filter depends on the file upload component being used. For Tomahawk <t:inputFileUpload>, check this answer and for PrimeFaces <p:fileUpload>, check this answer. Or, if you're actually not uploading a file at all, then remove the attribute altogether.

13. Make sure that the ActionEvent argument of actionListener is an javax.faces.event.ActionEvent and thus not java.awt.event.ActionEvent, which is what most IDEs suggest as 1st autocomplete option. Having no argument is wrong as well if you use actionListener="#{bean.method}". If you don't want an argument in your method, use actionListener="#{bean.method()}". Or perhaps you actually want to use action instead of actionListener. See also Differences between action and actionListener.

14. Make sure that no PhaseListener or any EventListener in the request-response chain has changed the JSF lifecycle to skip the invoke action phase by for example calling FacesContext#renderResponse() or FacesContext#responseComplete().

15. Make sure that no Filter or Servlet in the same request-response chain has blocked the request fo the FacesServlet somehow. For example, login/security filters such as Spring Security. Particularly in ajax requests that would by default end up with no UI feedback at all. See also Spring Security 4 and PrimeFaces 5 AJAX request handling.

16. If you are using a PrimeFaces <p:dialog> or a <p:overlayPanel>, then make sure that they have their own <h:form>. Because, these components are by default by JavaScript relocated to end of HTML <body>. So, if they were originally sitting inside a <form>, then they would now not anymore sit in a <form>. See also p:commandbutton action doesn't work inside p:dialog

17. Bug in the framework. For example, RichFaces has a "conversion error" when using a rich:calendar UI element with a defaultLabel attribute (or, in some cases, a rich:placeholder sub-element). This bug prevents the bean method from being invoked when no value is set for the calendar date. Tracing framework bugs can be accomplished by starting with a simple working example and building the page back up until the bug is discovered.

Debugging hints

In case you still stucks, it's time to debug. In the client side, press F12 in webbrowser to open the web developer toolset. Click the Console tab so see the JavaScript conosle. It should be free of any JavaScript errors. Below screenshot is an example from Chrome which demonstrates the case of submitting an <f:ajax> enabled button while not having <h:head> declared (as described in point 7 above).

Click the Network tab to see the HTTP traffic monitor. Submit the form and investigate if the request headers and form data and the response body are as per expectations. Below screenshot is an example from Chrome which demonstrates a successful ajax submit of a simple form with a single <h:inputText> and a single <h:commandButton> with <f:ajax execute="@form" render="@form">.

(warning: when you post screenshots from HTTP request headers like above from a production environment, then make sure you scramble/obfuscate any session cookies in the screenshot to avoid session hijacking attacks!)

In the server side, make sure that server is started in debug mode. Put a debug breakpoint in a method of the JSF component of interest which you expect to be called during processing the form submit. E.g. in case of UICommand component, that would be UICommand#queueEvent() and in case of UIInput component, that would be UIInput#validate(). Just step through the code execution and inspect if the flow and variables are as per expectations. Below screenshot is an example from Eclipse's debugger.

Your code has no problem. It does print the way you want. Alternatively, you can do this:

printf("%04x",a);

Thomas's solution is good enough for this matter.

If you want to use loop to access these three Answers, you first need to put there three into an array-like data structure ---- kind of like a principle. So loop is used for operating on an array-like data structure, not just simply to simplify typing task. And you cannot use FOR loop by simply just giving increasing-number-names to the elements.

I wrote the following code that works fine. But I think it only works with .wav format.

public static synchronized void playSound(final String url) {
  new Thread(new Runnable() {
  // The wrapper thread is unnecessary, unless it blocks on the
  // Clip finishing; see comments.
    public void run() {
      try {
        Clip clip = AudioSystem.getClip();
        AudioInputStream inputStream = AudioSystem.getAudioInputStream(
          Main.class.getResourceAsStream("/path/to/sounds/" + url));
        clip.open(inputStream);
        clip.start(); 
      } catch (Exception e) {
        System.err.println(e.getMessage());
      }
    }
  }).start();
}

function setPixel(imageData, x, y, r, g, b, a) {
    var index = 4 * (x + y * imageData.width);
    imageData.data[index+0] = r;
    imageData.data[index+1] = g;
    imageData.data[index+2] = b;
    imageData.data[index+3] = a;
}

I believe the correct way of doing it would be to use query builder expressions:

$now = new DateTimeImmutable();
$thirtyDaysAgo = $now->sub(new \DateInterval("P30D"));
$qb->select('e')
   ->from('Entity','e')
   ->add('where', $qb->expr()->between(
            'e.datefield',
            ':from',
            ':to'
        )
    )
   ->setParameters(array('from' => $thirtyDaysAgo, 'to' => $now));

http://docs.doctrine-project.org/en/latest/reference/query-builder.html#the-expr-class

Edit: The advantage this method has over any of the other answers here is that it's database software independent - you should let Doctrine handle the date type as it has an abstraction layer for dealing with this sort of thing.

If you do something like adding a string variable in the form 'Y-m-d' it will break when it goes to a database platform other than MySQL, for example.

How about something like this?

<input name="myvalue" type="text" onfocus="if(this.value=='enter value')this.value='';" onblur="if(this.value=='')this.value='enter value';">

This will clear upon focusing the first time, but then won't clear on subsequent focuses after the user enters their value, when left blank it restores the given value.

Before assigning a new column, if you have indexed data, you need to sort the index. At least in my case I had to:

data.set_index(['index_column'], inplace=True)
"if index is unsorted, assignment of a new column will fail"        
data.sort_index(inplace = True)
data.loc['index_value1', 'column_y'] = np.random.randn(data.loc['index_value1', 'column_x'].shape[0])

If your Main class is in a package called FileManagement, then try:

java -cp . FileManagement.Main

in the parent folder of the FileManagement folder.

If your Main class is not in a package (the default package) then cd to the FileManagement folder and try:

java -cp . Main

A space in a CSS selector selects child elements.

.btn input

This is basically what you wrote and it would select <input> elements within any element that has the btn class.

I think you're looking for

input[disabled].btn:hover, input[disabled].btn:active, input[disabled].btn:focus

This would select <input> elements with the disabled attribute and the btn class in the three different states of hover, active and focus.

Try adding this to the .htaccess file in that directory.

To Whom, deailing with share hosting environment and still chance to have Current PHP less than 7.0 Who does not have dirname( __FILE__, 2 ); it is possible to use following.

function dirname_safe($path, $level = 0){
    $dir = explode(DIRECTORY_SEPARATOR, $path);
    $level = $level * -1;
    if($level == 0) $level = count($dir);
    array_splice($dir, $level);
    return implode($dir, DIRECTORY_SEPARATOR).DIRECTORY_SEPARATOR;
}

print_r(dirname_safe(__DIR__, 2));

If you work on .NET 3.5 or newer, you can use the System.DirectoryServices.AccountManagement namespace and easily verify your credentials:

// create a "principal context" - e.g. your domain (could be machine, too)
using(PrincipalContext pc = new PrincipalContext(ContextType.Domain, "YOURDOMAIN"))
{
    // validate the credentials
    bool isValid = pc.ValidateCredentials("myuser", "mypassword");
}

It's simple, it's reliable, it's 100% C# managed code on your end - what more can you ask for? :-)

Read all about it here:

• Managing Directory Security Principals in the .NET Framework 3.5
• MSDN docs on System.DirectoryServices.AccountManagement

Update:

As outlined in this other SO question (and its answers), there is an issue with this call possibly returning True for old passwords of a user. Just be aware of this behavior and don't be too surprised if this happens :-) (thanks to @MikeGledhill for pointing this out!)

hack but works - (tested on chrome and mobile)

just add no break spaces   till it breaks - you might have to limit the tooltip size depending on the amount of content but for small text messages this works:

   etc

Tried everything above and this is the only thing that worked for me -

EDIT: Use stej's answer below. My own (partially incorrect) one is still reproduced here for reference:

You can use

Get-Variable foo -Scope Global

and trap the error that is raised when the variable doesn't exist.

For ubuntu users, run this command in your terminal [Tested in UBUNTU 16.04]

sudo apt-get -y install libcurl4-openssl-dev

post this install libraries the way you usually do in R using

install.packages("package name")

Properties props = new Properties();
URL resource = getClass().getClassLoader().getResource("data.properties");         
props.load(new InputStreamReader(resource.openStream(), "UTF8"));

Works like a charm

:-)

Even after reinstalling "Android SDK platform-tools" in my UBuntu-16.04 LTS problem persisted. I am using Eclipse-Oxygen. Copying dx.jar from /build-tools/25.0.3/lib into /build-tools/26.0.0-preview/lib solved my problem.

The following worked for me:

The interface consist of you logic methods plus additional identity method:

public interface MyService {
    String getType();
    void checkStatus();
}

Some implementations:

@Component
public class MyServiceOne implements MyService {
    @Override
    public String getType() {
        return "one";
    }

    @Override
    public void checkStatus() {
      // Your code
    }
}

@Component
public class MyServiceTwo implements MyService {
    @Override
    public String getType() {
        return "two";
    }

    @Override
    public void checkStatus() {
      // Your code
    }
}

@Component
public class MyServiceThree implements MyService {
    @Override
    public String getType() {
        return "three";
    }

    @Override
    public void checkStatus() {
      // Your code
    }
}

And the factory itself as following:

@Service
public class MyServiceFactory {

    @Autowired
    private List<MyService> services;

    private static final Map<String, MyService> myServiceCache = new HashMap<>();

    @PostConstruct
    public void initMyServiceCache() {
        for(MyService service : services) {
            myServiceCache.put(service.getType(), service);
        }
    }

    public static MyService getService(String type) {
        MyService service = myServiceCache.get(type);
        if(service == null) throw new RuntimeException("Unknown service type: " + type);
        return service;
    }
}

I've found such implementation easier, cleaner and much more extensible. Adding new MyService is as easy as creating another spring bean implementing same interface without making any changes in other places.

Simple and not time consuming answer with an example relevant to the question asked Follow this example:

 user = [{"name": "Dough", "age": 55}, 
            {"name": "Ben", "age": 44}, 
            {"name": "Citrus", "age": 33},
            {"name": "Abdullah", "age":22},
            ]
    print(sorted(user, key=lambda el: el["name"]))
    print(sorted(user, key= lambda y: y["age"]))

Look at the names in the list, they starts with D, B, C and A. And if you notice the ages, they are 55, 44, 33 and 22. The first print code

print(sorted(user, key=lambda el: el["name"]))

Results to:

[{'name': 'Abdullah', 'age': 22}, 
{'name': 'Ben', 'age': 44}, 
{'name': 'Citrus', 'age': 33}, 
{'name': 'Dough', 'age': 55}]

sorts the name, because by key=lambda el: el["name"] we are sorting the names and the names return in alphabetical order.

The second print code

print(sorted(user, key= lambda y: y["age"]))

Result:

[{'name': 'Abdullah', 'age': 22},
 {'name': 'Citrus', 'age': 33},
 {'name': 'Ben', 'age': 44}, 
 {'name': 'Dough', 'age': 55}]

sorts by age, and hence the list returns by ascending order of age.

Try this code for better understanding.

Ben has told you how to revert a merge commit, but it's very important you realize that in doing so

"...declares that you will never want the tree changes brought in by the merge. As a result, later merges will only bring in tree changes introduced by commits that are not ancestors of the previously reverted merge. This may or may not be what you want." (git-merge man page).

An article/mailing list message linked from the man page details the mechanisms and considerations that are involved. Just make sure you understand that if you revert the merge commit, you can't just merge the branch again later and expect the same changes to come back.

The easiest way to skip leading spaces in a string is, imho,

#include <stdio.h>

int main()
{
char *foo="     teststring      ";
char *bar;
sscanf(foo,"%s",bar);
printf("String is >%s<\n",bar);
    return 0;
}

Run php -f /common/configs/config_templates.inc.php to verify the validity of the PHP syntax in the file.

add into angular-cli.json

   "styles": [
         "../node_modules/bootstrap/dist/css/bootstrap.min.css",
        "styles.css"
      ],
      "scripts": [ 
         "../node_modules/bootstrap/dist/js/bootstrap.js"
      ],

It will be work, i checked it.

try with screen -d -r or screen -D -RR

There are a couple of differences between the & and && operators. The same differences apply to | and ||. The most important thing to keep in mind is that && is a logical operator that only applies to boolean operands, while & is a bitwise operator that applies to integer types as well as booleans.

With a logical operation, you can do short circuiting because in certain cases (like the first operand of && being false, or the first operand of || being true), you do not need to evaluate the rest of the expression. This is very useful for doing things like checking for null before accessing a filed or method, and checking for potential zeros before dividing by them. For a complex expression, each part of the expression is evaluated recursively in the same manner. For example, in the following case:

(7 == 8) || ((1 == 3) && (4 == 4))

Only the emphasized portions will evaluated. To compute the ||, first check if 7 == 8 is true. If it were, the right hand side would be skipped entirely. The right hand side only checks if 1 == 3 is false. Since it is, 4 == 4 does not need to be checked, and the whole expression evaluates to false. If the left hand side were true, e.g. 7 == 7 instead of 7 == 8, the entire right hand side would be skipped because the whole || expression would be true regardless.

With a bitwise operation, you need to evaluate all the operands because you are really just combining the bits. Booleans are effectively a one-bit integer in Java (regardless of how the internals work out), and it is just a coincidence that you can do short circuiting for bitwise operators in that one special case. The reason that you can not short-circuit a general integer & or | operation is that some bits may be on and some may be off in either operand. Something like 1 & 2 yields zero, but you have no way of knowing that without evaluating both operands.

I like the look of that apex utility. However its also good to know about the standard oracle functions you can use for this: subStr and inStr http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/functions001.htm

Unnamed namespaces are a utility to make an identifier translation unit local. They behave as if you would choose a unique name per translation unit for a namespace:

namespace unique { /* empty */ }
using namespace unique;
namespace unique { /* namespace body. stuff in here */ }

The extra step using the empty body is important, so you can already refer within the namespace body to identifiers like ::name that are defined in that namespace, since the using directive already took place.

This means you can have free functions called (for example) help that can exist in multiple translation units, and they won't clash at link time. The effect is almost identical to using the static keyword used in C which you can put in in the declaration of identifiers. Unnamed namespaces are a superior alternative, being able to even make a type translation unit local.

namespace { int a1; }
static int a2;

Both a's are translation unit local and won't clash at link time. But the difference is that the a1 in the anonymous namespace gets a unique name.

Read the excellent article at comeau-computing Why is an unnamed namespace used instead of static? (Archive.org mirror).

I understand that its been answered already. but I hope this will help someone in future and saves so much time and pain.

complete code is below: This one I did for a textbox to make it Autocomplete in CiviCRM. Hope it helps someone

PHP code on how I'm returning data to this jquery ajax call in autocomplete:

I had a similar problem and it was related to the version. In a python terminal check:

>> import xlrd
>> xlrd.__VERSION__

If you have '0.9.0' you can open almost all files. If you have '0.6.0' which was what I found on Ubuntu, you may have problems with newest Excel files. You can download the latest version of xlrd using the Distutils standard.

Here is my solution:

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Select The Difficulty Level");
builder.setCancelable(false);

That is a simple alert dialog, Federico gave you a site where you can look things up.

Here is a short example of how an alert dialog can be built.

new AlertDialog.Builder(this)
.setTitle("Title")
.setMessage("Do you really want to whatever?")
.setIcon(android.R.drawable.ic_dialog_alert)
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {

    public void onClick(DialogInterface dialog, int whichButton) {
        Toast.makeText(MainActivity.this, "Yaay", Toast.LENGTH_SHORT).show();
    }})
 .setNegativeButton(android.R.string.no, null).show();

I came here because I had the same problem.
What was the problem for me was that the procedure was defined in the package body, but not in the package header.
I was executing my function with a lose BEGIN END statement.

Your script could be stopping, not because of the PHP timeout but because of the timeout in the browser you're using to access the script (ie. Firefox, Chrome, etc). Unfortunately there's seldom an easy way to extend this timeout, and in most browsers you simply can't. An option you have here is to access the script over a terminal. For example, on Windows you would make sure the PHP executable is in your path variable and then I think you execute:

C:\path\to\script> php script.php

Or, if you're using the PHP CGI, I think it's:

C:\path\to\script> php-cgi script.php

Plus, you would also set ini_set('max_execution_time', 0); in your script as others have mentioned. When running a PHP script this way, I'm pretty sure you can use buffer flushing to echo out the script's progress to the terminal periodically if you wish. The biggest issue I think with this method is there's really no way of stopping the script once it's started, other than stopping the entire PHP process or service.

Use the -p flag and add /udp suffix to the port number.

-p 53160:53160/udp

Full command

sudo docker run -p 53160:53160 \
    -p 53160:53160/udp -p 58846:58846 \ 
    -p 8112:8112 -t -i aostanin/deluge /start.sh

If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.

You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile (EXPOSE does not publish the port):

EXPOSE 8285/udp

Here is a link with more Docker Networking info covered in the container docs: https://docs.docker.com/config/containers/container-networking/ (Courtesy of Old Pro in the comments)

Maybe try this:

<%= link_to "Add to cart", 
            :controller => "car", 
            :action => "add_to_cart", 
            :car => car.attributes %>

But I'd really like to see where the car object is getting setup for this page (i.e., the rest of the view).

Updated for Bootstrap 3 and 4

Bootstrap 3 and Bootstrap 4 docs refer two events you can use.

hide.bs.modal: This event is fired immediately when the hide instance method has been called.
hidden.bs.modal: This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).

And provide an example on how to use them:

$('#myModal').on('hidden.bs.modal', function () {
  // do something…
})

Legacy Bootstrap 2.3.2 answer

Bootstrap's documentation refers two events you can use.

hide: This event is fired immediately when the hide instance method has been called.
hidden: This event is fired when the modal has finished being hidden from the user (will wait for css transitions to complete).

And provides an example on how to use them:

$('#myModal').on('hidden', function () {
    // do something…
})

var obj = {...};
for (var key in obj) {
    var value = obj[key];

}

The php syntax is just sugar.

A note to this old question:

My reset.css had set border-spacing: 0, causing the corners to get cut off. I had to set it to 3px for my radius to work properly (value will depend on the radius in question).

you can get the product name like this

foreach ( $cart_object->cart_contents as  $value ) {
        $_product     = apply_filters( 'woocommerce_cart_item_product', $value['data'] );

        if ( ! $_product->is_visible() ) {
                echo $_product->get_title();
        } else {
                echo $_product->get_title();
        }


     }

I would not recommend changing the actual bootstrap CSS files. If you do not want to use Jako's first solution you can create a custom bootstrap style sheet with one of the available Bootstrap theme generator (Bootstrap theme generators). That way you can use 1 style sheet with all of the default Bootstrap CSS with just the one change to it that you want. With a Bootstrap theme generator you do not need to write any CSS. You only need to set the hex values for the color you want for the body (Scaffolding; bodyBackground).

You need to use the new operator when creating the object

Contacts.add(new Data(name, address, contact)); // Creating a new object and adding it to list - single step

or else

Data objt = new Data(name, address, contact); // Creating a new object
Contacts.add(objt); // Adding it to the list

and your constructor shouldn't contain void. Else it becomes a method in your class.

public Data(String n, String a, String c) { // Constructor has the same name as the class and no return type as such

I created a blank MS Document with Landscape setting and then opened it in notepad. Copied and pasted the following to my html page

<style type="text/css" media="print">
   @page Section1
    {size:11 8.5in;
    margin:.5in 13.6pt 0in 13.6pt;
    mso-header-margin:.5in;
    mso-footer-margin:.5in;
    mso-paper-source:4;}
div.Section1
    {page:Section1;}
</style>



<div class="Section1"> put  text / images / other stuff  </div>

The print preview shows the pages in a landscape size. This seems to be working fine on IE and Chrome, not tested on FF.

You have to catch the error just as you're already doing for your save() call and since you're handling multiple errors here, you can try multiple calls sequentially in a single do-catch block, like so:

func deleteAccountDetail() {
    let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
    let request = NSFetchRequest()
    request.entity = entityDescription

    do {
        let fetchedEntities = try self.Context!.executeFetchRequest(request) as! [AccountDetail]

        for entity in fetchedEntities {
            self.Context!.deleteObject(entity)
        }

        try self.Context!.save()
    } catch {
        print(error)
    }
}

Or as @bames53 pointed out in the comments below, it is often better practice not to catch the error where it was thrown. You can mark the method as throws then try to call the method. For example:

func deleteAccountDetail() throws {
    let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
    let request = NSFetchRequest()

    request.entity = entityDescription

    let fetchedEntities = try Context.executeFetchRequest(request) as! [AccountDetail]

    for entity in fetchedEntities {
        self.Context!.deleteObject(entity)
    }

    try self.Context!.save()
}

...

If your goal is to drop the dataframe, then you need to pass all columns. For me: the best way is to pass a list comprehension to the columns kwarg. This will then work regardless of the different columns in a df.

import pandas as pd

web_stats = {'Day': [1, 2, 3, 4, 2, 6],
             'Visitors': [43, 43, 34, 23, 43, 23],
             'Bounce_Rate': [3, 2, 4, 3, 5, 5]}
df = pd.DataFrame(web_stats)

df.drop(columns=[i for i in check_df.columns])

This is a little late for this question but others might benefit. I had a similar problem but had an added requirement for the text to correctly wrap in all device sizes. So in my case this worked. Need to setup the view port.

 .p
   {
   white-space: normal;
    overflow-wrap: break-word;
    width: 96vw;
   }

I resolved it by giving permission to the user on each of the directories that you're using, like so:

sudo chown user /home/user/git

and so on.

Try loading the website in another web browser such as Safari. Recently had this problem and for some reason, it worked after loading in a different browser.

You have to drop it and recreate it, but you don't have to incur the cost of revalidating the data if you don't want to.

alter table t drop constraint ck ;
alter table t add constraint ck check (n < 0) enable novalidate;

The enable novalidate clause will force inserts or updates to have the constraint enforced, but won't force a full table scan against the table to verify all rows comply.

Using 'document.body.clientHeight' you can get the seen height of the body elements

$('html, body').animate({
    scrollTop: $("#particularDivision").offset().top - document.body.clientHeight + $("#particularDivision").height()
}, 1000);

this scrolls at the id 'particularDivision'

As others said your Firewall needs to be configured to accept incoming calls on TCP Port 80.

in win 7+ (easy wizardry way)

1. go to windows firewall with advance security
2. Inbound Rules -> Action -> New Rule
3. select Predefined radio button and then select the last item - World Wide Web Services(HTTP)
4. click next and leave the next steps as they are (allow the connection)

• Because outbound traffic(from server to outside world) is allowed by default .it means for example http responses that web server is sending back to outside users and requests

• But inbound traffic (originating from outside world to the server) is blocked by default like the user web requests originating from their browser which cannot reach the web server by default and you must open it.

You can also take a closer look at inbound and outbound rules at this page

One thing you need to keep in mind is the size of your data set. I believe that Dillie-O was the only one who even remotely hit the point.

If you have a small, single user, consumer app then I would say DB. I have a DVD management app that uses the file system (in Program Files at that) and it is a PIA to backup. I wish EVERY time that they would store them in a db, and let me choose where to save that file.

For a larger commercial application then I would start to change my thinking. I used to work for a company that developed the county clerks information management application. We would store the images on disk, in an encoded format [to deal with FS problems with large numbers of files] based on the county assigned instrument number. This was useful on another front as the image could exist before the DB record (due to their workflow).

As with most things: 'It depends on what you are doing'

You can position both the image and the text with position:absolute or position:relative. Then the z-index property will work. E.g.

#sometext {
    position:absolute;
    z-index:1;

}
image.center {
    position:absolute;
    z-index:0;
}

Use whatever method you like to center it.

Another option/hack is to make the image the background, either on the whole page or just within the text box.

I'd go about this slightly differently. Structure your query to retrieve only what you need and split from there.

So make your query the following:

#                                vv or Job.find(1) vv
attachments = Attachment.where(job_id: @job.id, file_type: ["logo", "image"])
# or 
Job.includes(:attachments).where(id: your_job_id, attachments: { file_type: ["logo", "image"] })

And then partition the data:

@logos, @images = attachments.partition { |attachment| attachment.file_type == "logo" }

That will get the data you're after in a neat and efficient manner.

First, implement indexOf in JavaScript for browsers that don't already have it. For example, see Erik Arvidsson's array extras (also, the associated blog post). And then you can use indexOf without worrying about browser support. Here's a slightly optimised version of his indexOf implementation:

if (!Array.prototype.indexOf) {
    Array.prototype.indexOf = function (obj, fromIndex) {
        if (fromIndex == null) {
            fromIndex = 0;
        } else if (fromIndex < 0) {
            fromIndex = Math.max(0, this.length + fromIndex);
        }
        for (var i = fromIndex, j = this.length; i < j; i++) {
            if (this[i] === obj)
                return i;
        }
        return -1;
    };
}

It's changed to store the length so that it doesn't need to look it up every iteration. But the difference isn't huge. A less general purpose function might be faster:

var include = Array.prototype.indexOf ?
    function(arr, obj) { return arr.indexOf(obj) !== -1; } :
    function(arr, obj) {
        for(var i = -1, j = arr.length; ++i < j;)
            if(arr[i] === obj) return true;
        return false;
    };

I prefer using the standard function and leaving this sort of micro-optimization for when it's really needed. But if you're keen on micro-optimization I adapted the benchmarks that roosterononacid linked to in the comments, to benchmark searching in arrays. They're pretty crude though, a full investigation would test arrays with different types, different lengths and finding objects that occur in different places.

See below instructions for Ubuntu Linux with zsh:

1. Open terminal window (CTRL+ALT+T)
2. Run command nano ~/.zshrc to edit your profile
3. Add following lines in the opened file:

export ANDROID_SDK_HOME="~/Android/Sdk"
alias emulator="$ANDROID_SDK_HOME/emulator/emulator"

4. Save the file (CTRL+O, CTRL+X)
5. Source the profile by running command source ~/.zshrc or just log out and log back in
6. Test by running the command emulator -help in terminal

NOTE: Should be same for bash by replacing .zshrc with .bashrc

In my case I was developing an ASP.Net MVC5 web app and the certificate errors on my local dev machine (IISExpress certificate) started becoming a practical concern once I started working with service workers. Chrome simply wouldn't register my service worker because of the certificate error.

I did, however, notice that during my automated Selenium browser tests, Chrome seem to just "ignore" all these kinds of problems (e.g. the warning page about an insecure site), so I asked myself the question: How is Selenium starting Chrome for running its tests, and might it also solve the service worker problem?

Using Process Explorer on Windows, I was able to find out the command-line arguments with which Selenium is starting Chrome:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-background-networking --disable-client-side-phishing-detection --disable-default-apps --disable-hang-monitor --disable-popup-blocking --disable-prompt-on-repost --disable-sync --disable-web-resources --enable-automation --enable-logging --force-fieldtrials=SiteIsolationExtensions/Control --ignore-certificate-errors --log-level=0 --metrics-recording-only --no-first-run --password-store=basic --remote-debugging-port=12207 --safebrowsing-disable-auto-update --test-type=webdriver --use-mock-keychain --user-data-dir="C:\Users\Sam\AppData\Local\Temp\some-non-existent-directory" data:,

There are a bunch of parameters here that I didn't end up doing necessity-testing for, but if I run Chrome this way, my service worker registers and works as expected.

The only one that does seem to make a difference is the --user-data-dir parameter, which to make things work can be set to a non-existent directory (things won't work if you don't provide the parameter).

Hope that helps someone else with a similar problem. I'm using Chrome 60.0.3112.90.

To be able to install wheel files with a simple doubleclick on them you can do one the following:

1) Run two commands in command line under administrator privileges:

assoc .whl=pythonwheel
ftype pythonwheel=cmd /c pip.exe install "%1" ^& pause

2) Alternatively, they can be copied into a wheel.bat file and executed with 'Run as administrator' checkbox in the properties.

PS pip.exe is assumed to be in the PATH.

Update:

(1) Those can be combined in one line:

assoc .whl=pythonwheel& ftype pythonwheel=cmd /c pip.exe install -U "%1" ^& pause

(2) Syntax for .bat files is slightly different:

assoc .whl=pythonwheel& ftype pythonwheel=cmd /c pip.exe install -U "%%1" ^& pause

Also its output can be made more verbose:

@assoc .whl=pythonwheel|| echo Run me with administrator rights! && pause && exit 1
@ftype pythonwheel=cmd /c pip.exe install -U "%%1" ^& pause || echo Installation error && pause && exit 1
@echo Installation successfull & pause

see my blog post for details.

You can find the solution to this problem at: https://help.github.com/en/github/using-git/configuring-git-to-handle-line-endings

Simplified description of how you can solve this problem on windows:

Global settings for line endings The git config core.autocrlf command is used to change how Git handles line endings. It takes a single argument.

On Windows, you simply pass true to the configuration. For example: C:>git config --global core.autocrlf true

Good luck, I hope I helped.

The placeholder image you're including has a height of 50px. It is wrapped in an anchor (.navbar-brand) with a padding-top of 15px and a height of 50px. That's why the placeholder logo flows out of the bar. Try including a smaller image or play with the anchor's padding by assigning a class or an id to it wich you can reference in your css.

EDIT Or remove the static height: 50px from .navbar-brand. Your navbar will then take the height of its highest child.

h3 in bootstrap by default has a padding-top of 20px. Again, it is wrapped with that padding-top: 15px anchor. That's why it's not vertically centered like you want it. You could give the h3 a class or and id that resets the margin-top. And the same you could do with the padding of the anchor.

Here's something to play with: http://jsbin.com/jelec/1/edit?html,output

I like the solution from

http://www.nautsch.net/2008/10/28/class-von-type-parameter-java-generics/

public class Dada<T> {

    private Class<T> typeOfT;

    @SuppressWarnings("unchecked")
    public Dada() {
        this.typeOfT = (Class<T>)
                ((ParameterizedType)getClass()
                .getGenericSuperclass())
                .getActualTypeArguments()[0];
    }

When you concatenate strings, you need to allocate memory to store the result. The easiest to start with is String and &str:

fn main() {
    let mut owned_string: String = "hello ".to_owned();
    let borrowed_string: &str = "world";
    
    owned_string.push_str(borrowed_string);
    println!("{}", owned_string);
}

Here, we have an owned string that we can mutate. This is efficient as it potentially allows us to reuse the memory allocation. There's a similar case for String and String, as &String can be dereferenced as &str.

fn main() {
    let mut owned_string: String = "hello ".to_owned();
    let another_owned_string: String = "world".to_owned();
    
    owned_string.push_str(&another_owned_string);
    println!("{}", owned_string);
}

After this, another_owned_string is untouched (note no mut qualifier). There's another variant that consumes the String but doesn't require it to be mutable. This is an implementation of the Add trait that takes a String as the left-hand side and a &str as the right-hand side:

fn main() {
    let owned_string: String = "hello ".to_owned();
    let borrowed_string: &str = "world";
    
    let new_owned_string = owned_string + borrowed_string;
    println!("{}", new_owned_string);
}

Note that owned_string is no longer accessible after the call to +.

What if we wanted to produce a new string, leaving both untouched? The simplest way is to use format!:

fn main() {
    let borrowed_string: &str = "hello ";
    let another_borrowed_string: &str = "world";
    
    let together = format!("{}{}", borrowed_string, another_borrowed_string);

    // After https://rust-lang.github.io/rfcs/2795-format-args-implicit-identifiers.html
    // let together = format!("{borrowed_string}{another_borrowed_string}");

    println!("{}", together);
}

Note that both input variables are immutable, so we know that they aren't touched. If we wanted to do the same thing for any combination of String, we can use the fact that String also can be formatted:

fn main() {
    let owned_string: String = "hello ".to_owned();
    let another_owned_string: String = "world".to_owned();
    
    let together = format!("{}{}", owned_string, another_owned_string);

    // After https://rust-lang.github.io/rfcs/2795-format-args-implicit-identifiers.html
    // let together = format!("{owned_string}{another_owned_string}");
    println!("{}", together);
}

You don't have to use format! though. You can clone one string and append the other string to the new string:

fn main() {
    let owned_string: String = "hello ".to_owned();
    let borrowed_string: &str = "world";
    
    let together = owned_string.clone() + borrowed_string;
    println!("{}", together);
}

Note - all of the type specification I did is redundant - the compiler can infer all the types in play here. I added them simply to be clear to people new to Rust, as I expect this question to be popular with that group!

You likely want to use onupdate=datetime.now so that UPDATEs also change the last_updated field.

SQLAlchemy has two defaults for python executed functions.

• default sets the value on INSERT, only once
• onupdate sets the value to the callable result on UPDATE as well.

I haven't done SWING development since my early CS classes but if it wasn't built in you could just inherit javax.swing.AbstractButton and create your own. Should be pretty simple to wire something together with their existing framework.

I had same problem with a site on our direct admin hosted site. I added

The reason is that mysql expecting end of the row symbol in the text file after last specified column, and this symbol is char(10) or '\n'. Depends on operation system where text file created or if you created your text file yourself, it can be other combination (Windows uses '\r\n' (chr(13)+chr(10)) as rows separator). Thus, if you use Windows generated text file, add following suffix to your LOAD command: “ LINES TERMINATED BY '\r\n' ”. Otherwise, check how rows are separated in your text file. On default mysql expecting char(10) as rows separator.

Your question is not particularly clear, but in case you want to send POST data to a url without using a form, you can use either fsockopen or curl.

SQL supports qualifying a column by prefixing the reference with either the full table name:

SELECT tbl_names.id, tbl_section.id, name, section
  FROM tbl_names
  JOIN tbl_section ON tbl_section.id = tbl_names.id 

...or a table alias:

SELECT n.id, s.id, n.name, s.section
  FROM tbl_names n
  JOIN tbl_section s ON s.id = n.id 

The table alias is the recommended approach -- why type more than you have to?

Why Do These Queries Look Different?

Secondly, my answers use ANSI-92 JOIN syntax (yours is ANSI-89). While they perform the same, ANSI-89 syntax does not support OUTER joins (RIGHT, LEFT, FULL). ANSI-89 syntax should be considered deprecated, there are many on SO who will not vote for ANSI-89 syntax to reinforce that. For more information, see this question.

if you want to do it with pure HTML solution ,you can delete the border in the table if you want...or you can add align="center" attribute to your img tag like this:

<img align="center" width="100%" height="100%" src="http://dummyimage.com/68x68/000/fff" />

If you overload the function __str__() for your Person class, you can omit the part with map(str, ...). Another way for this is creating a function, just like you wrote:

...

write_list(MyList)

There is in Python 3.* the argument sep for the print() function. Take a look at documentation.

In MySQL Workbench you need an INDEX to edit, no need it to be PK (although adding a PK is a solution as well).

You can make a regular INDEX or compound INDEX. That's all MySQL WB needs to fix the Read only thing (I have v. 6.2 with MariaDB v. 10.1.4):

Just right click table, select "Alter table..." then go to "Indexes" tab. In the left pane put a custom name for your index, and in the middle pane checkmark one (make sure the vale will be unique) or more fields (just make sure the combination is unique)

document.evaluate() (DOM Level 3 XPath) is supported in Firefox, Chrome, Safari and Opera - the only major browser missing is MSIE. Nevertheless, jQuery supports basic XPath expressions: http://docs.jquery.com/DOM/Traversing/Selectors#XPath_Selectors (moved into a plugin in the current jQuery version, see https://plugins.jquery.com/xpath/). It simply converts XPath expressions into equivalent CSS selectors however.

For me the best option is to use CSS pseudo elements, so for disc bullet styling it would look like that:

ul {_x000D_
  list-style-type: none;_x000D_
}_x000D_
_x000D_
li {_x000D_
  position: relative;_x000D_
}_x000D_
_x000D_
li:before {_x000D_
  content: '';_x000D_
  display: block;_x000D_
  position: absolute;_x000D_
  width: 5px; /* adjust to suit your needs */_x000D_
  height: 5px; /* adjust to suit your needs */_x000D_
  border-radius: 50%;_x000D_
  left: -15px; /* adjust to suit your needs */_x000D_
  top: 0.5em;_x000D_
  background: #f00; /* adjust to suit your needs */_x000D_
}

<ul>_x000D_
  <li>first</li>_x000D_
  <li>second</li>_x000D_
  <li>third</li>_x000D_
</ul>

Notes:

• width and height should have equal values to keep pointers rounded
• you may set border-radius to zero if you want to have square list bullets

For more bullets styles you may use other css shapes https://css-tricks.com/examples/ShapesOfCSS/ (choose this which doesn't require pseudo elements to work, so for example triangles)

For the more inexperienced, I have decided to add an example to demonstrate how to input and output an ArrayList of Integer arrays based on this question here.

    ArrayList<Integer[]> arrayList = new ArrayList<Integer[]>();
    while(n > 0)
    {
        int d = scan.nextInt();
       Integer temp[] = new Integer[d];
        for (int i = 0 ; i < d ; i++)
        {
            int t = scan.nextInt();
            temp[i]=Integer.valueOf(t);
        }
        arrayList.add(temp);
        n--;
    }//n is the size of the ArrayList that has been taken as a user input & d is the size 
    //of each individual array.

     //to print something  out from this ArrayList, we take in two 
    // values,index and index1 which is the number of the line we want and 
    // and the position of the element within that line (since the question
    // followed a 1-based numbering scheme, I did not change it here)

Thanks to this answer on this question here, I got the correct answer. I believe this satisfactorily answers OP's question, albeit a little late and can serve as an explanation for those with less experience.

queryForMap is appropriate if you want to get a single row. You are selecting without a where clause, so you probably want to queryForList. The error is probably indicative of the fact that queryForMap wants one row, but you query is retrieving many rows.

Check out the docs. There is a queryForList that takes just sql; the return type is a

List<Map<String,Object>>.

So once you have the results, you can do what you are doing. I would do something like

List results = template.queryForList(sql);

for (Map m : results){
   m.get('userid');
   m.get('username');
} 

I'll let you fill in the details, but I would not iterate over keys in this case. I like to explicit about what I am expecting.

If you have a User object, and you actually want to load User instances, you can use the queryForList that takes sql and a class type

queryForList(String sql, Class<T> elementType)

(wow Spring has changed a lot since I left Javaland.)

There is no => for if.
Use if %energy% GEQ %m2enc%

See if /? for some other details.

A little more maintainable and secure approach.

An update to expand on what I meant and how it works.

1. Secure. MDN is pretty explicit about the use of Math.random for anything related to security:

   Math.random() does not provide cryptographically secure random numbers. Do not use them for anything related to security. Use the Web Crypto API instead, and more precisely the window.crypto.getRandomValues() method.

   Looking at the can-i-use for getRandomValues in 2020 you probably don't need the msCrypto and Math.random fallback any more, unless you care about ancient browsers.

2. Maintainable is mostly about the RegExp _pattern as an easy way to define what character classes you allow in the password. But also about the 3 things where each does its job: defines a pattern, gets a random byte as securely as possible, provides a public API to combine the two.

var Password = {
 
  _pattern : /[a-zA-Z0-9_\-\+\.]/,
  
  
  _getRandomByte : function()
  {
    // http://caniuse.com/#feat=getrandomvalues
    if(window.crypto && window.crypto.getRandomValues) 
    {
      var result = new Uint8Array(1);
      window.crypto.getRandomValues(result);
      return result[0];
    }
    else if(window.msCrypto && window.msCrypto.getRandomValues) 
    {
      var result = new Uint8Array(1);
      window.msCrypto.getRandomValues(result);
      return result[0];
    }
    else
    {
      return Math.floor(Math.random() * 256);
    }
  },
  
  generate : function(length)
  {
    return Array.apply(null, {'length': length})
      .map(function()
      {
        var result;
        while(true) 
        {
          result = String.fromCharCode(this._getRandomByte());
          if(this._pattern.test(result))
          {
            return result;
          }
        }        
      }, this)
      .join('');  
  }    
    
};

<input type='text' id='p'/><br/>
<input type='button' value ='generate' onclick='document.getElementById("p").value = Password.generate(16)'>

ALTER TABLE {tableName} ADD COLUMN COLNew {type};
UPDATE {tableName} SET COLNew = {base on {type} pass value here};

This update is required to handle the null value, inputting a default value as you require. As in your case, you need to call the SELECT query and you will get the order of columns, as paxdiablo already said:

SELECT name, colnew, qty, rate FROM{tablename}

and in my opinion, your column name to get the value from the cursor:

private static final String ColNew="ColNew";
String val=cursor.getString(cursor.getColumnIndex(ColNew));

so if the index changes your application will not face any problems.

This is the safe way in the sense that otherwise, if you are using CREATE temptable or RENAME table or CREATE, there would be a high chance of data loss if not handled carefully, for example in the case where your transactions occur while the battery is running out.

if(isset($rule["type"]) && ($rule["type"] == "radio") || ($rule["type"] == "checkbox") )
{
    if(!isset($data[$field]))
        $data[$field]="";
}

Like Unix shells, PowerShell supports > redirects with most of the variations known from Unix, including 2>&1 (though weirdly, order doesn't matter - 2>&1 > file works just like the normal > file 2>&1).

Like most modern Unix shells, PowerShell also has a shortcut for redirecting both standard error and standard output to the same device, though unlike other redirection shortcuts that follow pretty much the Unix convention, the capture all shortcut uses a new sigil and is written like so: *>.

So your implementation might be:

& myjob.bat *>> $logfile

Starting from the answer given by @chaos, but with a few modifications:

• You should always use ORDER BY if you use LIMIT. There is no implicit order guaranteed for an RDBMS table. You may usually get rows in the order of the primary key, but you can't rely on this, nor is it portable.

• If you order by in the descending order, you don't need to know the number of rows in the table beforehand.

• You must give a correlation name (aka table alias) to a derived table.

Here's my version of the query:

SELECT `id`
FROM (
    SELECT `id`, `val`
    FROM `big_table`
    ORDER BY `id` DESC
    LIMIT $n
) AS t
WHERE t.`val` = $certain_number;

In RSA crypto, when you generate a key pair, it's completely arbitrary which one you choose to be the public key, and which is the private key. If you encrypt with one, you can decrypt with the other - it works in both directions.

So, it's fairly simple to see how you can encrypt a message with the receiver's public key, so that the receiver can decrypt it with their private key.

A signature is proof that the signer has the private key that matches some public key. To do this, it would be enough to encrypt the message with that sender's private key, and include the encrypted version alongside the plaintext version. To verify the sender, decrypt the encrypted version, and check that it is the same as the plaintext.

Of course, this means that your message is not secret. Anyone can decrypt it, because the public key is well known. But when they do so, they have proved that the creator of the ciphertext has the corresponding private key.

However, this means doubling the size of your transmission - plaintext and ciphertext together (assuming you want people who aren't interested in verifying the signature, to read the message). So instead, typically a signature is created by creating a hash of the plaintext. It's important that fake hashes can't be created, so cryptographic hash algorithms such as SHA-2 are used.

So:

• To generate a signature, make a hash from the plaintext, encrypt it with your private key, include it alongside the plaintext.
• To verify a signature, make a hash from the plaintext, decrypt the signature with the sender's public key, check that both hashes are the same.

var array = string.split(',')

and good morning, too, since I have to type 30 chars ...

Or, you can clip the select. Something along the lines of:

select { width:200px; position:absolute; clip:rect(0, 170px, 50px, 0); }

This should clip 30px of the right side of select box, stripping away the arrow. Now supply a 170px background image and voila, styled select

Steps to generate Create table DDLs for all the tables in the Hive database and export into text file to run later:

step 1)
create a .sh file with the below content, say hive_table_ddl.sh

#!/bin/bash
rm -f tableNames.txt
rm -f HiveTableDDL.txt
hive -e "use $1; show tables;" > tableNames.txt  
wait
cat tableNames.txt |while read LINE
   do
   hive -e "use $1;show create table $LINE;" >>HiveTableDDL.txt
   echo  -e "\n" >> HiveTableDDL.txt
   done
rm -f tableNames.txt
echo "Table DDL generated"

step 2)

Run the above shell script by passing 'db name' as paramanter

>bash hive_table_dd.sh <<databasename>>

output :

All the create table statements of your DB will be written into the HiveTableDDL.txt

<head>
    <script type="text/javascript">
        function SetMaxLength () {
            var input = document.getElementById("myInput");
            input.maxLength = 10;
        }
    </script>
</head>
<body>
    <input id="myInput" type="text" size="20" />
</body>

If you have context data along with css and js in your html template. Than you have good option to use pdfjs.

In your code you can use like this.

from django.template.loader import get_template
import pdfkit
from django.conf import settings

context={....}
template = get_template('reports/products.html')
html_string = template.render(context)
pdfkit.from_string(html_string, os.path.join(settings.BASE_DIR, "media", 'products_report-%s.pdf'%(id)))

In your HTML you can link extranal or internal css and js, it will generate best quality of pdf.

If that really is all that's in your CSS file, then yes, nothing will happen. You need a selector, even if it's as simple as body:

body {
    background-image: url(...);
}

I solved the problem by cat'ing all the pems together:

cat cert.pem chain.pem fullchain.pem >all.pem
openssl pkcs12 -export -in all.pem -inkey privkey.pem -out cert_and_key.p12 -name tomcat -CAfile chain.pem -caname root -password MYPASSWORD
keytool -importkeystore -deststorepass MYPASSWORD -destkeypass MYPASSWORD -destkeystore MyDSKeyStore.jks -srckeystore cert_and_key.p12 -srcstoretype PKCS12 -srcstorepass MYPASSWORD -alias tomcat
keytool -import -trustcacerts -alias root -file chain.pem -keystore MyDSKeyStore.jks -storepass MYPASSWORD

(keytool didn't know what to do with a PKCS7 formatted key)

I got all the pems from letsencrypt

50% of C++ programmers like to set their pointers to null after a delete:

template<typename T>    
void moronic_delete(T*& p)
{
    delete p;
    p = nullptr;
}

Without the reference, you would only be changing a local copy of the pointer, not affecting the caller.

Here's a good drop-in solution for perfectly centered circular X icon buttons

• Using only CSS
• Not relying on a font
• The thickness and length of the tines of the X can be configured without affecting centering, using width and height in the pseudo element rule .close::before, .close::after
• Screen reader support using aria-label
• Works on a light or dark background by using transparent grays and currentColor to adapt to the current text color specified on the button or an ancestor.

.close {
    vertical-align: middle;
    border: none;
    color: inherit;
    border-radius: 50%;
    background: transparent;
    position: relative;
    width: 32px;
    height: 32px;
    opacity: 0.6;
}
.close:focus,
.close:hover {
    opacity: 1;
    background: rgba(128, 128, 128, 0.5);
}
.close:active {
    background: rgba(128, 128, 128, 0.9);
}
/* tines of the X */
.close::before,
.close::after {
    content: " ";
    position: absolute;
    top: 50%;
    left: 50%;
    height: 20px;
    width: 4px;
    background-color: currentColor;
}
.close::before {
    transform: translate(-50%, -50%) rotate(45deg);
}
.close::after {
    transform: translate(-50%, -50%) rotate(-45deg);
}

<div style="padding: 15px">
    <button class="close" aria-label="Close"></button>
</div>
<div style="background: black; color: white; padding: 15px">

Something you can try is using the bind method, I think this achieves what you were asking for. If nothing else, it's still very useful.

function doClick(elem, func) {
  var diffElem = document.getElementById('some_element'); //could be the same or different element than the element in the doClick argument
  diffElem.addEventListener('click', func.bind(diffElem, elem))
}

function clickEvent(elem, evt) {
  console.log(this);
  console.log(elem); 
  // 'this' and elem can be the same thing if the first parameter 
  // of the bind method is the element the event is being attached to from the argument passed to doClick
  console.log(evt);
}

var elem = document.getElementById('elem_to_do_stuff_with');
doClick(elem, clickEvent);

You can't expect ObjectInputStream to automagically convert text into objects. The hexadecimal 54657374 is "Test" as text. You must be sending it directly as bytes.

$Query_String  = explode("&", explode("?", $_SERVER['REQUEST_URI'])[1] );

Array ( [ 0] => link=www.google.com )

You have to use GROUP BY so you will have multiple records returned,

SELECT  COUNT(*) TotalCount, 
        b.category_id, 
        b.category_name 
FROM    table1 a
        INNER JOIN table2 b
            ON a.category_id = b.category_id 
WHERE   a.colour <> 'red'
GROUP   BY b.category_id, b.category_name

Raymond Chen has a really excellent blog post on this:

GUIDs are globally unique, but substrings of GUIDs aren't

The concatenation operator + is a binary infix operator which, when applied to lists, returns a new list containing all the elements of each of its two operands. The list.append() method is a mutator on list which appends its single object argument (in your specific example the list c) to the subject list. In your example this results in c appending a reference to itself (hence the infinite recursion).

An alternative to '+' concatenation

The list.extend() method is also a mutator method which concatenates its sequence argument with the subject list. Specifically, it appends each of the elements of sequence in iteration order.

An aside

Being an operator, + returns the result of the expression as a new value. Being a non-chaining mutator method, list.extend() modifies the subject list in-place and returns nothing.

Arrays

I've added this due to the potential confusion which the Abel's answer above may cause by mixing the discussion of lists, sequences and arrays. Arrays were added to Python after sequences and lists, as a more efficient way of storing arrays of integral data types. Do not confuse arrays with lists. They are not the same.

From the array docs:

Arrays are sequence types and behave very much like lists, except that the type of objects stored in them is constrained. The type is specified at object creation time by using a type code, which is a single character.

Try this:

function someFunction(site)     
{     
    return site.replace(/\/$/, "");
} 

This should be the Unix load average. Wikipedia has a nice article about this.

The numbers show the average load of the CPU in different time intervals. From left to right: last minute/last five minutes/last fifteen minutes

you can also just run it with a shell, for example:

bash example.txt

sh example.txt

Your current code:

ggplot(histogram, aes(f0, fill = utt)) + geom_histogram(alpha = 0.2)

is telling ggplot to construct one histogram using all the values in f0 and then color the bars of this single histogram according to the variable utt.

What you want instead is to create three separate histograms, with alpha blending so that they are visible through each other. So you probably want to use three separate calls to geom_histogram, where each one gets it's own data frame and fill:

ggplot(histogram, aes(f0)) + 
    geom_histogram(data = lowf0, fill = "red", alpha = 0.2) + 
    geom_histogram(data = mediumf0, fill = "blue", alpha = 0.2) +
    geom_histogram(data = highf0, fill = "green", alpha = 0.2) +

Here's a concrete example with some output:

dat <- data.frame(xx = c(runif(100,20,50),runif(100,40,80),runif(100,0,30)),yy = rep(letters[1:3],each = 100))

ggplot(dat,aes(x=xx)) + 
    geom_histogram(data=subset(dat,yy == 'a'),fill = "red", alpha = 0.2) +
    geom_histogram(data=subset(dat,yy == 'b'),fill = "blue", alpha = 0.2) +
    geom_histogram(data=subset(dat,yy == 'c'),fill = "green", alpha = 0.2)

which produces something like this:

Edited to fix typos; you wanted fill, not colour.

If you are going to use this conversion a lot, consider calculating once and putting the results in a dictionary:

>>> import string
>>> di=dict(zip(string.letters,[ord(c)%32 for c in string.letters]))
>>> di['c'] 
3

The advantage is dictionary lookups are very fast vs iterating over a list on every call.

>>> for c in sorted(di.keys()):
>>>    print "{0}:{1}  ".format(c, di[c])
# what you would expect....

Other methods were mentioned so let us please acknowledge that, at the time of writing, we are in the 21st century. Let's park the local bus browser opening, and fly with an XMLHTTP GET request (XHR GET for short).

Wiki moment:

XHR is an API in the form of an object whose methods transfer data between a web browser and a web server. The object is provided by the browser's JavaScript environment

It's a fast method for retrieving data that doesn't require opening a browser. The server response can be read into an HTMLDocument and the process of grabbing the table continued from there.

Note that javascript rendered/dynamically added content will not be retrieved as there is no javascript engine running (which there is in a browser).

In the below code, the table is grabbed by its id cr1.

In the helper sub, WriteTable, we loop the columns (td tags) and then the table rows (tr tags), and finally traverse the length of each table row, table cell by table cell. As we only want data from columns 1 and 8, a Select Case statement is used specify what is written out to the sheet.

That's all. I solve the problem by this way.Hope it might work for you.

The solution is given here. https://abcofcomputing.blogspot.com/2017/06/php7-unable-to-load-phpcurldll.html

You just need to bind a variable into the directive "ng-class" and change it from the controller. Here is an example of how to do this:

var app = angular.module("ap",[]);_x000D_
_x000D_
app.controller("con",function($scope){_x000D_
  $scope.class = "red";_x000D_
  $scope.changeClass = function(){_x000D_
    if ($scope.class === "red")_x000D_
      $scope.class = "blue";_x000D_
    else_x000D_
      $scope.class = "red";_x000D_
  };_x000D_
});

.red{_x000D_
  color:red;_x000D_
}_x000D_
_x000D_
.blue{_x000D_
  color:blue;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
<body ng-app="ap" ng-controller="con">_x000D_
  <div ng-class="class">{{class}}</div>_x000D_
  <button ng-click="changeClass()">Change Class</button>    _x000D_
</body>

Here is the example working on jsFiddle

Observations:

• #include <cstring> should introduce std::strcpy().
• using namespace std; (as written in medico.h) introduces any identifiers from std:: into the global namespace.

Aside from using namespace std; being somewhat clumsy once the application grows larger (as it introduces one hell of a lot of identifiers into the global namespace), and that you should never use using in a header file (see below!), using namespace does not affect identifiers introduced after the statement.

(using namespace std is written in the header, which is included in medico.cpp, but #include <cstring> comes after that.)

My advice: Put the using namespace std; (if you insist on using it at all) into medico.cpp, after any includes, and use explicit std:: in medico.h.

strcmpi() is not a standard function at all; while being defined on Windows, you have to solve case-insensitive compares differently on Linux.

(On general terms, I would like to point to this answer with regards to "proper" string handling in C and C++ that takes Unicode into account, as every application should. Summary: The standard cannot handle these things correctly; do use ICU.)

warning: deprecated conversion from string constant to ‘char*’

A "string constant" is when you write a string literal (e.g. "Hello") in your code. Its type is const char[], i.e. array of constant characters (as you cannot change the characters). You can assign an array to a pointer, but assigning to char *, i.e. removing the const qualifier, generates the warning you are seeing.

OT clarification: using in a header file changes visibility of identifiers for anyone including that header, which is usually not what the user of your header file wants. For example, I could use std::string and a self-written ::string just perfectly in my code, unless I include your medico.h, because then the two classes will clash.

Don't use using in header files.

And even in implementation files, it can introduce lots of ambiguity. There is a case to be made to use explicit namespacing in implementation files as well.

Just to complete the answer above that use .Net.

In this code the path is stored in the %1 argument (which is written in the registry under quote that are escaped: \"%1\" ). To retrieve it, we need the $arg (inbuilt arg). Don't forget the quote around $FilePath.

# Get the File path:  
$FilePath = $args
Write-Host "FilePath: " $FilePath

# Get the complete file name:
$file_name_complete = [System.IO.Path]::GetFileName("$FilePath")
Write-Host "fileNameFull :" $file_name_complete

# Get File Name Without Extension:
$fileNameOnly = [System.IO.Path]::GetFileNameWithoutExtension("$FilePath")
Write-Host "fileNameOnly :" $fileNameOnly

# Get the Extension:
$fileExtensionOnly = [System.IO.Path]::GetExtension("$FilePath")
Write-Host "fileExtensionOnly :" $fileExtensionOnly

Here's a relatively easy method to do this. Throw a GridView into your layout, setting the stretch mode to stretch the column widths, set the spacing to 0 (or whatever you want), and set the number of columns to 2:

res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <GridView
        android:id="@+id/gridview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:verticalSpacing="0dp"
        android:horizontalSpacing="0dp"
        android:stretchMode="columnWidth"
        android:numColumns="2"/>

</FrameLayout>

Make a custom ImageView that maintains its aspect ratio:

src/com/example/graphicstest/SquareImageView.java

public class SquareImageView extends ImageView {
    public SquareImageView(Context context) {
        super(context);
    }

    public SquareImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public SquareImageView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        setMeasuredDimension(getMeasuredWidth(), getMeasuredWidth()); //Snap to width
    }
}

Make a layout for a grid item using this SquareImageView and set the scaleType to centerCrop:

res/layout/grid_item.xml

<?xml version="1.0" encoding="utf-8"?>

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
             android:layout_width="match_parent"
             android:layout_height="match_parent">

    <com.example.graphicstest.SquareImageView
        android:id="@+id/picture"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop"/>

    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:paddingTop="15dp"
        android:paddingBottom="15dp"
        android:layout_gravity="bottom"
        android:textColor="@android:color/white"
        android:background="#55000000"/>

</FrameLayout>

Now make some sort of adapter for your GridView:

src/com/example/graphicstest/MyAdapter.java

private final class MyAdapter extends BaseAdapter {
    private final List<Item> mItems = new ArrayList<Item>();
    private final LayoutInflater mInflater;

    public MyAdapter(Context context) {
        mInflater = LayoutInflater.from(context);

        mItems.add(new Item("Red",       R.drawable.red));
        mItems.add(new Item("Magenta",   R.drawable.magenta));
        mItems.add(new Item("Dark Gray", R.drawable.dark_gray));
        mItems.add(new Item("Gray",      R.drawable.gray));
        mItems.add(new Item("Green",     R.drawable.green));
        mItems.add(new Item("Cyan",      R.drawable.cyan));
    }

    @Override
    public int getCount() {
        return mItems.size();
    }

    @Override
    public Item getItem(int i) {
        return mItems.get(i);
    }

    @Override
    public long getItemId(int i) {
        return mItems.get(i).drawableId;
    }

    @Override
    public View getView(int i, View view, ViewGroup viewGroup) {
        View v = view;
        ImageView picture;
        TextView name;

        if (v == null) {
            v = mInflater.inflate(R.layout.grid_item, viewGroup, false);
            v.setTag(R.id.picture, v.findViewById(R.id.picture));
            v.setTag(R.id.text, v.findViewById(R.id.text));
        }

        picture = (ImageView) v.getTag(R.id.picture);
        name = (TextView) v.getTag(R.id.text);

        Item item = getItem(i);

        picture.setImageResource(item.drawableId);
        name.setText(item.name);

        return v;
    }

    private static class Item {
        public final String name;
        public final int drawableId;

        Item(String name, int drawableId) {
            this.name = name;
            this.drawableId = drawableId;
        }
    }
}

Set that adapter to your GridView:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    GridView gridView = (GridView)findViewById(R.id.gridview);
    gridView.setAdapter(new MyAdapter(this));
}

And enjoy the results:

this is the best way to solve this

 getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

You could use jQuery's grep method:

$.grep(carBrands, function(obj) { return obj.name == "ford"; });

But as you specify no jQuery, you could just make a derivative of the function. From the source code:

function grepArray( elems, callback, inv ) {  
    var ret = [];  

    // Go through the array, only saving the items  
    // that pass the validator function  
    for ( var i = 0, length = elems.length; i < length; i++ ) {  
        if ( !inv !== !callback( elems[ i ], i ) ) {  
            ret.push( elems[ i ] );  
        }  
    }  

    return ret;  
}  

grepArray(carBrands, function(obj) { return obj.name == "ford"; });

I had an issue where I had to replace the text of link, but I couldn't use JavaScript nor could I directly change the text of a hyperlink as it was compiled down from XML. Also, I couldn't use pseudo elements, or they didn't seem to work when I had tried them.

Basically, I put the text I wanted into a span and put the anchor tag underneath it and wrapped both in a div. I basically moved the anchor tag up via CSS and then made the font transparent. Now when you hover over the span, it "acts" like a link. A really hacky way of doing this, but this is how you can have a link with different text...

This is a fiddle of how I got around this issue

My HTML

<div class="field">
    <span>This is your link text</span><br/>
    <a href="//www.google.com" target="_blank">This is your actual link</a>
</div>

My CSS

 div.field a {
     color: transparent;
     position: absolute;
     top:1%;
 }
 div.field span {
     display: inline-block;
 }

The CSS will need to change based off your requirements, but this is a general way of doing what you are asking.

I believe there is a simpler solution. You must use Html.Hidden instead of Html.HiddenFor. Look:

@Html.Hidden("CRN", ViewData["crn"]);

This will create an INPUT tag of type="hidden", with id="CRN" and name="CRN", and the correct value inside the value attribute.

Hope it helps!

The best and simpler setup with Nginx and Nodejs is to use Nginx as an HTTP and TCP load balancer with proxy_protocol enabled. In this context, Nginx will be able to proxy incoming requests to nodejs, and also terminate SSL connections to the backend Nginx server(s), and not to the proxy server itself. (SSL-PassThrough)

In my opinion, there is no point in giving non-SSL examples, since all web apps are (or should be) using secure environments.

And lastly, a sample of 2 nodejs webservers: First server:

var http = require('http');

http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello From Nodejs\n');
}).listen(8080, "192.168.1.4");
console.log('Server running at http://192.168.1.4:8080/');

Second server:

var http = require('http');

http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello From Nodejs\n');
}).listen(8080, "192.168.1.5");
console.log('Server running at http://192.168.1.5:8080/');

Now everything should be perfectly working and load-balanced.
