Setting the Color property alone will guarantee an exact match. Excel 2003 can only handle 56 colors at once. The good news is that you can assign any rgb value at all to those 56 slots (which are called ColorIndexs). When you set a cell's color using the Color property this causes Excel to use the nearest "ColorIndex". Example: Setting a cell to RGB 10,20,50 (or 3281930) will actually cause it to be set to color index 56 which is 51,51,51 (or 3355443).

If you want to be assured you got an exact match, you need to change a ColorIndex to the RGB value you want and then change the Cell's ColorIndex to said value. However you should be aware that by changing the value of a color index you change the color of all cells already using that color within the workbook. To give an example, Red is ColorIndex 3. So any cell you made Red you actually made ColorIndex 3. And if you redefine ColorIndex 3 to be say, purple, then your cell will indeed be made purple, but all other red cells in the workbook will also be changed to purple.

There are several strategies to deal with this. One way is to choose an index not yet in use, or just one that you think will not be likely to be used. Another way is to change the RGB value of the nearest ColorIndex so your change will be subtle. The code I have posted below takes this approach. Taking advantage of the knowledge that the nearest ColorIndex is assigned, it assigns the RGB value directly to the cell (thereby yielding the nearest color) and then assigns the RGB value to that index.

Sub Example()
    Dim lngColor As Long
    lngColor = RGB(10, 20, 50)
    With Range("A1").Interior
        .Color = lngColor
        ActiveWorkbook.Colors(.ColorIndex) = lngColor
    End With
End Sub

C does not have an implementation of for-each. When parsing an array as a point the receiver does not know how long the array is, thus there is no way to tell when you reach the end of the array. Remember, in C int* is a point to a memory address containing an int. There is no header object containing information about how many integers that are placed in sequence. Thus, the programmer needs to keep track of this.

However, for lists, it is easy to implement something that resembles a for-each loop.

for(Node* node = head; node; node = node.next) {
   /* do your magic here */
}

To achieve something similar for arrays you can do one of two things.

1. use the first element to store the length of the array.
2. wrap the array in a struct which holds the length and a pointer to the array.

The following is an example of such struct:

typedef struct job_t {
   int count;
   int* arr;
} arr_t;

r+ The existing file is opened to the beginning for both reading and writing. w+ Same as w except both for reading and writing.

Not sure why you aren't able to set it. In the source, PUBLIC_URL takes precedence over homepage

const envPublicUrl = process.env.PUBLIC_URL;
...
const getPublicUrl = appPackageJson =>
  envPublicUrl || require(appPackageJson).homepage;

You can try setting breakpoints in their code to see what logic is overriding your environment variable.

In my case I got also this issue from my ASP Core 3.1 projets. I thing that for some reason visual studio ignore the IP/Port setting in the project property and start it on 5000 and 5001. I discovered this while attempting to start my Core 3.1 projects from prompt using dotnet run

And this post helped me How to specify the port an ASP.NET Core application is hosted on?

It suggest to

• Specify the port in the appsettings.json or maybe appsettings.development.json. (see lower)
• Close Visual Studio
• Delete /.vs, /bin, /obj folders
• Restart Visual Studio.

appsettings.json / appsettings.development.json content

 {   
      /***************************
      "Urls": "http://localhost:49438", <==== HERE
      /***************************/
      
      "Logging": {
        "LogLevel": {
          "Default": "Information",
          "Microsoft": "Warning",
          "Microsoft.Hosting.Lifetime": "Information"
        }
      },
      "AllowedHosts": "*",
      "connectionStrings": { ...  }
    } 

The accepted answer (using font awesome) is the right one. But since I just wanted the red variant to show on validation errors, I ended using an addon package, kindly offered on this site.

Just edited the url paths in css files since they are absolute (start with /) and I prefer to be relative. Like this:

.icon-red {background-image: url("../img/glyphicons-halflings-red.png") !important;}
.icon-purple {background-image: url("../img/glyphicons-halflings-purple.png") !important;}
.icon-blue {background-image: url("../img/glyphicons-halflings-blue.png") !important;}
.icon-lightblue {background-image: url("../img/glyphicons-halflings-lightblue.png") !important;}
.icon-green {background-image: url("../img/glyphicons-halflings-green.png") !important;}
.icon-yellow {background-image: url("../img/glyphicons-halflings-yellow.png") !important;}
.icon-orange {background-image: url("../img/glyphicons-halflings-orange.png") !important;}

LENGTH() does return the string length (just verified). I suppose that your data is padded with blanks - try

SELECT typ, LENGTH(TRIM(t1.typ))
FROM AUTA_VIEW t1;

instead.

As OraNob mentioned, another cause could be that CHAR is used in which case LENGTH() would also return the column width, not the string length. However, the TRIM() approach also works in this case.

jQuery .val()

  var foo = $('#multiple').val(); 

Goto Properties -> maven Remove the pom.xml from the activate profiles and follow the below steps.

Steps :

1. Delete the .m2 repository
2. Restart the Eclipse IDE
3. Refresh and Rebuild it

There are two solutions for this are :-

(1) do not put onClick in xml

(2) remove

button.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
            // TODO Auto-generated method stub
    }
});

and put

public void setLogin(View v) {
    // Your code here
}

1. Use ref attribute on DOM element for reference

<div class="content scrollable" ref="msgContainer">
    <!-- content -->
</div>

2. You need to setup a WATCH

  data() {
    return {
      count: 5
    };
  },
  watch: {
    count: function() {
      this.$nextTick(function() {
        var container = this.$refs.msgContainer;
        container.scrollTop = container.scrollHeight + 120;
      });
    }
  }

3. Ensure you're using proper CSS

.scrollable {
  overflow: hidden;
  overflow-y: scroll;
  height: calc(100vh - 20px);
}

Suppose s = "ZWzaAd"

To sort above string the simple solution will be below one.

print ''.join(sorted(s))

//Pour inserer :
            $pdf = addslashes(file_get_contents($_FILES['inputname']['tmp_name']));
            $filetype = addslashes($_FILES['inputname']['type']);//pour le test 
            $namepdf = addslashes($_FILES['inputname']['name']);            
            if (substr($filetype, 0, 11) == 'application'){
            $mysqli->query("insert into tablepdf(pdf_nom,pdf)value('$namepdf','$pdf')");
            }
//Pour afficher :
            $row = $mysqli->query("SELECT * FROM tablepdf where id=(select max(id) from tablepdf)");
            foreach($row as $result){
                 $file=$result['pdf'];
            }
            header('Content-type: application/pdf');
            echo file_get_contents('data:application/pdf;base64,'.base64_encode($file));

To start it right after installation, I generate a batch file with installutil followed by sc start

It's not ideal, but it works....

instead of getting Notepad++, You can simply Open the file with Wordpad and then Save As - Plain Text document

Position the outer div however you want, then position the inner divs using absolute. They'll all stack up.

.inner {_x000D_
  position: absolute;_x000D_
}

<div class="outer">_x000D_
   <div class="inner">1</div>_x000D_
   <div class="inner">2</div>_x000D_
   <div class="inner">3</div>_x000D_
   <div class="inner">4</div>_x000D_
</div>

If you are going to override it I don't see a valid reason to keep this static. I would suggest the use of abstraction (see example code). :

     public interface Person {
        public abstract String getName();
       //this will be different for each person, so no need to make it concrete
        public abstract void setName(String name);
    }

Now we can add the Dad:

public class Dad implements Person {

    private String name;

    public Dad(String name) {
        setName(name);
    }

    @Override
    public final String getName() {
    return name;
    }

    @Override
    public final void setName(String name) {
        this.name = name;
    }
}

the son:

public class Son implements Person {

    private String name;

    public Son(String name) {
        setName(name);
    }

    @Override
    public final String getName() {
        return name;
    }

    @Override
    public final void setName(String name) {
        this.name = name;
    }
}

and Dad met a nice lady:

public class StepMom implements Person {

    private String name;

    public StepMom(String name) {
        setName(name);
    }

    @Override
    public final String getName() {
        return name;
    }

    @Override
    public final void setName(String name) {
        this.name = name;
    }
}

Looks like we have a family, lets tell the world their names:

public class ConsoleGUI {

    public static void main(String[] args) {
        List<Person> family = new ArrayList<Person>();
        family.add(new Son("Tommy"));
        family.add(new StepMom("Nancy"));
        family.add(new Dad("Dad"));
        for (Person person : family) {
            //using the getName vs printName lets the caller, in this case the
            //ConsoleGUI determine versus being forced to output through the console. 
            System.out.print(person.getName() + " ");
            System.err.print(person.getName() + " ");
            JOptionPane.showMessageDialog(null, person.getName());
    }
}

}

System.out Output : Tommy Nancy Dad
System.err is the same as above(just has red font)
JOption Output:
Tommy then
Nancy then
Dad

To combine bitmasks you want to use bitwise-or. In the trivial case where every value you combine has exactly 1 bit on (like your example), it's equivalent to adding them. If you have overlapping bits however, or'ing them handles the case gracefully.

To decode the bitmasks you and your value with a mask, like so:

if(val & (1<<1)) SusanIsOn();
if(val & (1<<2)) BobIsOn();
if(val & (1<<3)) KarenIsOn();

This is not an Array. Better declare it like this:

var assoc_pagine = {};
assoc_pagine["home"]=0;
assoc_pagine["about"]=1;
assoc_pagine["work"]=2;

or

var assoc_pagine = {
                 home:0,
                 about:1,
                 work:2
               };

To check if an object contains some label you simply do something like this:

if('work' in assoc_pagine){
   // do your thing
};

This error sometimes occurs in a situation like this:

#ifndef NAN
#include <stdlib.h>
#define NAN (strtod("NAN",NULL))
#endif

static void init_random(uint32_t initseed=0)
{
    if (initseed==0)
    {
        struct timeval tv;
        gettimeofday(&tv, NULL);
        seed=(uint32_t) (4223517*getpid()*tv.tv_sec*tv.tv_usec);
    }
    else
        seed=initseed;
#if !defined(CYGWIN) && !defined(__INTERIX)
    //seed=42
    //SG_SPRINT("initializing random number generator with %d (seed size %d)\n", seed, RNG_SEED_SIZE)
    initstate(seed, CMath::rand_state, RNG_SEED_SIZE);
#endif
}

If the following code lines not run in the run-time:

#ifndef NAN
#include <stdlib.h>
#define NAN (strtod("NAN",NULL))
#endif

you will face with an error in your code like something as follows; because initstate is placed in the stdlib.h file and it's not included:

In file included from ../../shogun/features/SubsetStack.h:14:0, 
                 from ../../shogun/features/Features.h:21,

                 from MatlabInterface.h:15, 
                 from matlabInterface.cpp:7:

@SamMonk your technique is great. But you can use laravel form helper to do so. I have a customer and dogs relationship.

On your controller

$dogs = Dog::lists('name', 'id');

On customer create view you can use.

{{ Form::label('dogs', 'Dogs') }}
{{ Form::select('dogs[]', $dogs, null, ['id' => 'dogs', 'multiple' => 'multiple']) }}

Third parameter accepts a list of array a well. If you define a relationship on your model you can do this:

{{ Form::label('dogs', 'Dogs') }}
{{ Form::select('dogs[]', $dogs, $customer->dogs->lists('id'), ['id' => 'dogs', 'multiple' => 'multiple']) }}

Update For Laravel 5.1

The lists method now returns a Collection. Upgrading To 5.1.0

{!! Form::label('dogs', 'Dogs') !!}
{!! Form::select('dogs[]', $dogs, $customer->dogs->lists('id')->all(), ['id' => 'dogs', 'multiple' => 'multiple']) !!}

Round numbers, yes. This is the main example source.

If you want to connect to a MySQL database using JavaScript, you can use Node.js and a library called mysql. You can create queries, and get results as an array of registers. If you want to try it, you can use my project generator to create a backend and choose MySQL as the database to connect. Then, just expose your new REST API or GraphQL endpoint to your front and start working with your MySQL database.

OLD ANSWER LEFT BY NOSTALGIA

THEN

As I understand the question and correct me if I am wrong, it refers to the classic server model with JavaScript only on the client-side. In this classic model, with LAMP servers (Linux, Apache, MySQL, PHP) the language in contact with the database was PHP, so to request data to the database you need to write PHP scripts and echo the returning data to the client. Basically, the distribution of the languages according to physical machines was:

1. Server Side: PHP and MySQL.
2. Client Side: HTML/CSS and JavaScript.

This answered to an MVC model (Model, View, Controller) where we had the following functionality:

1. MODEL: The model is what deals with the data, in this case, the PHP scripts that manage variables or that access data stored, in this case in our MySQL database and send it as JSON data to the client.
2. VIEW: The view is what we see and it should be completely independent of the model. It just needs to show the data contained in the model, but it shouldn't have relevant data on it. In this case, the view uses HTML and CSS. HTML to create the basic structure of the view, and CSS to give the shape to this basic structure.
3. CONTROLLER: The controller is the interface between our model and our view. In this case, the language used is JavaScript and it takes the data the model send us as a JSON package and put it inside the containers that offer the HTML structure. The way the controller interacts with the model is by using AJAX. We use GET and POST methods to call PHP scripts on the server-side and to catch the returned data from the server.

For the controller, we have really interesting tools like jQuery, as "low-level" library to control the HTML structure (DOM), and then new, more high-level ones as Knockout.js that allow us to create observers that connect different DOM elements updating them when events occur. There is also Angular.js by Google that works in a similar way, but seems to be a complete environment. To help you to choose among them, here you have two excellent analyses of the two tools: Knockout vs. Angular.js and Knockout.js vs. Angular.js. I am still reading. Hope they help you.

NOW

In modern servers based in Node.js, we use JavaScript for everything. Node.js is a JavaScript environment with many libraries that work with Google V8, Chrome JavaScript engine. The way we work with these new servers is:

1. Node.js and Express: The mainframe where the server is built. We can create a server with a few lines of code or even use libraries like Express to make even easier to create the server. With Node.js and Express, we will manage the petitions to the server from the clients and will answer them with the appropriate pages.
2. Jade: To create the pages we use a templating language, in this case, Jade, that allow us to write web pages as we were writing HTML but with differences (it take a little time but is easy to learn). Then, in the code of the server to answer the client's petitions, we just need to render the Jade code into a "real" HTML code.
3. Stylus: Similar to Jade but for CSS. In this case, we use a middleware function to convert the stylus file into a real CSS file for our page.

Then we have a lot of packages we can install using the NPM (Node.js package manager) and use them directly in our Node.js server just requiring it (for those of you that want to learn Node.js, try this beginner tutorial for an overview). And among these packages, you have some of them to access databases. Using this you can use JavaScript on the server-side to access My SQL databases.

But the best you can do if you are going to work with Node.js is to use the new NoSQL databases like MongoDB, based on JSON files. Instead of storing tables like MySQL, it stores the data in JSON structures, so you can put different data inside each structure like long numeric vectors instead of creating huge tables for the size of the biggest one.

I hope this brief explanation becomes useful to you, and if you want to learn more about this, here you have some resources you can use:

• Egghead: This site is full of great short tutorials about JavaScript and its environment. It worths a try. And the make discounts from time to time.
• Code School: With a free and very interesting course about Chrome Developer tools to help you to test the client-side.
• Codecademy: With free courses about HTML, CSS, JavaScript, jQuery, and PHP that you can follow with online examples.
• 10gen Education: With everything you need to know about MongoDB in tutorials for different languages.
• W3Schools: This one has tutorials about all this and you can use it as a reference place because it has a lot of shortcode examples really useful.
• Udacity: A place with free video courses about different subjects with a few interesting ones about web development and my preferred, an amazing WebGL course for 3D graphics with JavaScript.

I hope it helps you to start.

Have fun!

SKU stands for Stock-keeping Unit. It's more for inventory tracking purpose.

The purpose of having an SKU is so that you can tie the app sales to whatever internal SKU number that your accounting is using.

This is not a complete new solution but a correction for afwebservant's solution:

      end

   ELSE

Here's what I've been doing:

  public void displayError(final String errorText) {
    Runnable doDisplayError = new Runnable() {
        public void run() {
            Toast.makeText(getApplicationContext(), errorText, Toast.LENGTH_LONG).show();
        }
    };
    messageHandler.post(doDisplayError);
}

That should allow the method to be called from either thread.

Where messageHandler is declared in the activity as ..

Handler messageHandler = new Handler();

A one-liner (no essential difference to the answers above though):

document.body.appendChild(document.createElement('script')).src = 'source.js';

What you probably want is for...of, a relatively new construct built for the express purpose of enumerating the values of iterable objects:

let myArray = ["a","b","c","d"];_x000D_
for (let item of myArray) {_x000D_
  console.log(item);_x000D_
}

... as distinct from for...in, which enumerates property names (presumably¹ numeric indices in the case of arrays). Your loop displayed unexpected results because you didn't use the property names to get the corresponding values via bracket notation... but you could have:

let myArray = ["a","b","c","d"];_x000D_
for (let key in myArray) {_x000D_
  let value =  myArray[key]; // get the value by key_x000D_
  console.log("key: %o, value: %o", key, value);_x000D_
}

_{¹ Unfortunately, someone may have added enumerable properties to the array or its prototype chain which are not numeric indices... or they may have assigned an index leaving unassigned indices in the interim range. The issues are explained pretty well here. The main takeaway is that it's best to loop explicitly from 0 to array.length - 1 rather than using for...in.}

So, this is not (as I'd originally thought) an academic question, i.e.:

Without regard for practicality, is it possible to avoid length when iterating over an array?

According to your comment (emphasis mine):

[...] why do I need to calculate the size of an array whereas the interpreter can know it.

You have a misguided aversion to Array.length. It's not calculated on the fly; it's updated whenever the length of the array changes. You're not going to see performance gains by avoiding it (apart from caching the array length rather than accessing the property):

Now, even if you did get some marginal performance increase, I doubt it would be enough to justify the risk of dealing with the aforementioned issues.

For people looking this up now:

It seems that now setting the User-Agent header is allowed since Firefox 43. See https://developer.mozilla.org/en-US/docs/Glossary/Forbidden_header_name for the current list of forbidden headers.

The value returned by Date.prototype.toLocaleString is implementation dependent, so you get what you get. You can try to parse the string to remove seconds, but it may be different in different browsers so you'd need to make allowance for every browser in use.

Creating your own, unambiguous format isn't difficult using Date methods. For example:

function formatTimeHHMMA(d) {
  function z(n){return (n<10?'0':'')+n}
  var h = d.getHours();
  return (h%12 || 12) + ':' + z(d.getMinutes()) + ' ' + (h<12? 'AM' :'PM');
}

Do you have a pointer to a vector because that's how you've coded it? You may want to reconsider this and use a (possibly const) reference. For example:

#include <iostream>
#include <vector>

using namespace std;

void foo(vector<int>* a)
{
    cout << a->at(0) << a->at(1) << a->at(2) << endl;
    // expected result is "123"
}

int main()
{
    vector<int> a;
    a.push_back(1);
    a.push_back(2);
    a.push_back(3);

    foo(&a);
}

While this is a valid program, the general C++ style is to pass a vector by reference rather than by pointer. This will be just as efficient, but then you don't have to deal with possibly null pointers and memory allocation/cleanup, etc. Use a const reference if you aren't going to modify the vector, and a non-const reference if you do need to make modifications.

Here's the references version of the above program:

#include <iostream>
#include <vector>

using namespace std;

void foo(const vector<int>& a)
{
    cout << a[0] << a[1] << a[2] << endl;
    // expected result is "123"
}

int main()
{
    vector<int> a;
    a.push_back(1);
    a.push_back(2);
    a.push_back(3);

    foo(a);
}

As you can see, all of the information contained within a will be passed to the function foo, but it will not copy an entirely new value, since it is being passed by reference. It is therefore just as efficient as passing by pointer, and you can use it as a normal value rather than having to figure out how to use it as a pointer or having to dereference it.

For Microsoft SQL Server or PostgreSQL you may want to try this syntax

SELECT constants FROM (VALUES ('[email protected]'), ('[email protected]'), ('[email protected]')) AS MyTable(constants)

You can also view an SQL Fiddle here: http://www.sqlfiddle.com/#!17/9eecb/34703/0

You have $headers .= '...'; followed by $headers = '...';; the second line is overwriting the first.

Just put the $headers .= "Bcc: $emailList\r\n"; say after the Content-type line and it should be fine.

On a side note, the To is generally required; mail servers might mark your message as spam otherwise.

$headers  = "From: [email protected]\r\n" .
  "X-Mailer: php\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$headers .= "Bcc: $emailList\r\n";

Try the following:

with open('data.txt', 'r') as myfile:
    data = myfile.read()

    sentences = data.split('\\n')
    for sentence in sentences:
        print(sentence)

Caution: It does not remove the \n. It is just for viewing the text as if there were no \n

The definitions for NP complete problems above is correct, but I thought I might wax lyrical about their philosophical importance as nobody has addressed that issue yet.

Almost all complex problems you'll come up against will be NP Complete. There's something very fundamental about this class, and which just seems to be computationally different from easily solvable problems. They sort of have their own flavour, and it's not so hard to recognise them. This basically means that any moderately complex algorithm is impossible for you to solve exactly -- scheduling, optimising, packing, covering etc.

But not all is lost if a problem you'll encounter is NP Complete. There is a vast and very technical field where people study approximation algorithms, which will give you guarantees for being close to the solution of an NP complete problem. Some of these are incredibly strong guarantees -- for example, for 3sat, you can get a 7/8 guarantee through a really obvious algorithm. Even better, in reality, there are some very strong heuristics, which excel at giving great answers (but no guarantees!) for these problems.

Note that two very famous problems -- graph isomorphism and factoring -- are not known to be P or NP.

Been doing it for years. Never run into a problem.

I usually set up my DB's to have one table that contains all the keys and the modified dates and such. Haven't run into a problem of duplicate keys ever.

The only drawback that it has is when you are writing some queries to find some information quickly you are doing a lot of copying and pasting of the keys. You don't have the short easy to remember ids anymore.

It has nothing to do with append. tuple(3, 4) all by itself raises that error.

The reason is that, as the error message says, tuple expects an iterable argument. You can make a tuple of the contents of a single object by passing that single object to tuple. You can't make a tuple of two things by passing them as separate arguments.

Just do (3, 4) to make a tuple, as in your first example. There's no reason not to use that simple syntax for writing a tuple.

Use DATE() function:

select * from follow_queue group by DATE(follow_date)

I ran into this problem because I had multiple wildcard entries for the same ports. You can easily check this by executing apache2ctl -S:

# apache2ctl -S
[Wed Oct 22 18:02:18 2014] [warn] _default_ VirtualHost overlap on port 30000, the first has precedence
[Wed Oct 22 18:02:18 2014] [warn] _default_ VirtualHost overlap on port 20001, the first has precedence
VirtualHost configuration:
11.22.33.44:80       is a NameVirtualHost
         default server xxx.com (/etc/apache2/sites-enabled/xxx.com.conf:1)
         port 80 namevhost xxx.com (/etc/apache2/sites-enabled/xxx.com.conf:1)
         [...]
11.22.33.44:443      is a NameVirtualHost
         default server yyy.com (/etc/apache2/sites-enabled/yyy.com.conf:37)
         port 443 namevhost yyy.com (/etc/apache2/sites-enabled/yyy.com.conf:37)
wildcard NameVirtualHosts and _default_ servers:
*:80                   hostname.com (/etc/apache2/sites-enabled/000-default:1)
*:20001                hostname.com (/etc/apache2/sites-enabled/000-default:33)
*:30000                hostname.com (/etc/apache2/sites-enabled/000-default:57)
_default_:443          hostname.com (/etc/apache2/sites-enabled/default-ssl:2)
*:20001                hostname.com (/etc/apache2/sites-enabled/default-ssl:163)
*:30000                hostname.com (/etc/apache2/sites-enabled/default-ssl:178)
Syntax OK

Notice how at the beginning of the output are a couple of warning lines. These will indicate which ports are creating the problems (however you probably already knew that).

Next, look at the end of the output and you can see exactly which files and lines the virtualhosts are defined that are creating the problem. In the above example, port 20001 is assigned both in /etc/apache2/sites-enabled/000-default on line 33 and /etc/apache2/sites-enabled/default-ssl on line 163. Likewise *:30000 is listed in 2 places. The solution (in my case) was simply to delete one of the entries.

I know its too late to answer, but in my scenario below code was not working.

 $('#datepicker').val("");
 $('#datepicker').val('').datepicker('update');
 $('#datepicker').datepicker('update','');

here is my solution.

 $('#datepicker').val('').datepicker('remove').datepicker();

I did clear datepicker value first then removed datepicker and again reinitialize datepicker. its resolved my problem.

PHP can be easily utilized for reading bar codes printed on paper documents. Connecting manual barcode reader to the computer via USB significantly extends usability of PHP (or any other web programming language) into tasks involving document and product management, like finding a book records in the database or listing all bills for a particular customer.

Following sections briefly describe process of connecting and using manual bar code reader with PHP.

The usage of bar code scanners described in this article are in the same way applicable to any web programming language, such as ASP, Python or Perl. This article uses only PHP since all tests have been done with PHP applications.

What is a bar code reader (scanner)

Bar code reader is a hardware pluggable into computer that sends decoded bar code strings into computer. The trick is to know how to catch that received string. With PHP (and any other web programming language) the string will be placed into focused input HTML element in browser. Thus to catch received bar code string, following must be done:

just before reading the bar code, proper input element, such as INPUT TEXT FIELD must be focused (mouse cursor is inside of the input field). once focused, start reading the code when the code is recognized (bar code reader usually shortly beeps), it is send to the focused input field. By default, most of bar code readers will append extra special character to decoded bar code string called CRLF (ENTER). For example, if decoded bar code is "12345AB", then computer will receive "12345ABENTER". Appended character ENTER (or CRLF) emulates pressing the key ENTER causing instant submission of the HTML form:

<form action="search.php" method="post">
    <input name="documentID" onmouseover="this.focus();" type="text">
</form>

Choosing the right bar code scanner

When choosing bar code reader, one should consider what types of bar codes will be read with it. Some bar codes allow only numbers, others will not have checksum, some bar codes are difficult to print with inkjet printers, some barcode readers have narrow reading pane and cannot read for example barcodes with length over 10 cm. Most of barcode readers support common barcodes, such as EAN8, EAN13, CODE 39, Interleaved 2/5, Code 128 etc.

For office purposes, the most suitable barcodes seem to be those supporting full range of alphanumeric characters, which might be:

• code 39 - supports 0-9, uppercased A-Z, and few special characters (dash, comma, space, $, /, +, %, *)
• code 128 - supports 0-9, a-z, A-Z and other extended characters

Other important things to note:

• make sure all standard barcodes are supported, at least CODE39, CODE128, Interleaved25, EAN8, EAN13, PDF417, QRCODE.
• use only standard USB plugin cables. RS232 interfaces are meant for industrial usage, rather than connecting to single PC.
• the cable should be long enough, at least 1.5 m - the longer the better.
• bar code reader plugged into computer should not require other power supply - it should power up simply by connecting to PC via USB.
• if you also need to print bar code into generated PDF documents, you can use TCPDF open source library that supports most of common 2D bar codes.

Installing scanner drivers

Installing manual bar code reader requires installing drivers for your particular operating system and should be normally supplied with purchased bar code reader.

Once installed and ready, bar code reader turns on signal LED light. Reading the barcode starts with pressing button for reading.

Scanning the barcode - how does it work?

STEP 1 - Focused input field ready for receiving character stream from bar code scanner:

STEP 2 - Received barcode string from bar code scanner is immediatelly submitted for search into database, which creates nice "automated" effect:

STEP 3 - Results returned after searching the database with submitted bar code:

Conclusion

It seems, that utilization of PHP (and actually any web programming language) for scanning the bar codes has been quite overlooked so far. However, with natural support of emulated keypress (ENTER/CRLF) it is very easy to automate collecting & processing recognized bar code strings via simple HTML (GUI) fomular.

The key is to understand, that recognized bar code string is instantly sent to the focused HTML element, such as INPUT text field with appended trailing character ASCII 13 (=ENTER/CRLF, configurable option), which instantly sends input text field with populated received barcode as a HTML formular to any other script for further processing.

You could add the time component

WHERE mydate<='2008-11-25 23:59:59'

but that might fail on DST switchover dates if mydate is '2008-11-25 24:59:59', so it's probably safest to grab everything before the next date:

WHERE mydate < '2008-11-26 00:00:00'

I was getting the error : CryptographicException 'Keyset does not exist' when i run the MVC application.

Solution was : to give access to the personal certificates to the account that application pool is running under. In my case it was to add IIS_IUSRS and choosing the right location resolved this issue.

RC on the Certificate - > All tasks -> Manage Private Keys -> Add->  
For the From this location : Click on Locations and make sure to select the Server name. 
In the Enter the object names to select : IIS_IUSRS and click ok. 

I was having this same problem and found the solution in the anwser to another question: https://stackoverflow.com/a/1951132/425749

Basically, installing CDT does not install a compiler, and Eclipse's error messages are not explicit about this.

Turn on gzip if you want to do it properly. You can also just do something like this:

$this->output = preg_replace(
    array(
        '/ {2,}/',
        '/<!--.*?-->|\t|(?:\r?\n[ \t]*)+/s'
    ),
    array(
        ' ',
        ''
    ),
    $this->output
);

This removes about 30% of the page size by turning your html into one line, no tabs, no new lines, no comments. Mileage may vary

There are a lot of answers to this question, which never worked for me (including suggesting getPosition() which doesn't seem to be a method available for markers objects). The only method that worked for me in maps V3 is (simply) :

var lat = marker.lat();
var long = marker.lng();

I'd strongly recommend to keep working with swap files (in case Vim crashes).

You can set the directory where the swap files are stored, so they don't clutter your normal directories:

set swapfile
set dir=~/tmp

You can also look up the sql,username,machine,port information and get to the actual process which holds the connection

SELECT O.OBJECT_NAME, S.SID, S.SERIAL#, P.SPID, S.PROGRAM,S.USERNAME,
S.MACHINE,S.PORT , S.LOGON_TIME,SQ.SQL_FULLTEXT 
FROM V$LOCKED_OBJECT L, DBA_OBJECTS O, V$SESSION S, 
V$PROCESS P, V$SQL SQ 
WHERE L.OBJECT_ID = O.OBJECT_ID 
AND L.SESSION_ID = S.SID AND S.PADDR = P.ADDR 
AND S.SQL_ADDRESS = SQ.ADDRESS;

The accepted answer only shows files in the current directory's tree. To show all of the tracked files that have been committed (on the current branch), use

git ls-tree --full-tree --name-only -r HEAD

• --full-tree makes the command run as if you were in the repo's root directory.
• -r recurses into subdirectories. Combined with --full-tree, this gives you all committed, tracked files.
• --name-only removes SHA / permission info for when you just want the file paths.
• HEAD specifies which branch you want the list of tracked, committed files for. You could change this to master or any other branch name, but HEAD is the commit you have checked out right now.

This is the method from the accepted answer to the ~duplicate question https://stackoverflow.com/a/8533413/4880003.

String s = "a.b.c.d";
int charCount = s.length() - s.replaceAll("\\.", "").length();

ReplaceAll(".") would replace all characters.

PhiLho's solution uses ReplaceAll("[^.]",""), which does not need to be escaped, since [.] represents the character 'dot', not 'any character'.

For the offline tools that support multiple inputs, the best I've seen so far is https://github.com/wolverdude/GenSON/ I'd like to see a tool that takes filenames on standard input because I have thousands of files. However, I run out of open file descriptors, so make sure the files are closed. I'd also like to see JSON Schema generators that handle recursion. I am now working on generating Java classes from JSON objects in hopes of going to JSON Schema from my Java classes. Here is my GenSON script if you are curious or want to identify bugs in it.

Actually, curl has an option explicitly for this: --resolve

Instead of curl -H 'Host: yada.com' http://127.0.0.1/something

use curl --resolve 'yada.com:80:127.0.0.1' http://yada.com/something

What's the difference, you ask?

Among others, this works with HTTPS. Assuming your local server has a certificate for yada.com, the first example above will fail because the yada.com certificate doesn't match the 127.0.0.1 hostname in the URL.

The second example works correctly with HTTPS.

In essence, passing a "Host" header via -H does hack your Host into the header set, but bypasses all of curl's host-specific intelligence. Using --resolve leverages all of the normal logic that applies, but simply pretends the DNS lookup returned the data in your command-line option. It works just like /etc/hosts should.

Note --resolve takes a port number, so for HTTPS you would use

curl --resolve 'yada.com:443:127.0.0.1' https://yada.com/something

From git reset

"pull" or "merge" always leaves the original tip of the current branch in ORIG_HEAD.

git reset --hard ORIG_HEAD

Resetting hard to it brings your index file and the working tree back to that state, and resets the tip of the branch to that commit.

git reset --merge ORIG_HEAD

After inspecting the result of the merge, you may find that the change in the other branch is unsatisfactory. Running "git reset --hard ORIG_HEAD" will let you go back to where you were, but it will discard your local changes, which you do not want. "git reset --merge" keeps your local changes.

Before any patches are applied, ORIG_HEAD is set to the tip of the current branch.
This is useful if you have problems with multiple commits, like running 'git am' on the wrong branch or an error in the commits that is more easily fixed by changing the mailbox (e.g. +errors in the "From:" lines).

In addition, merge always sets '.git/ORIG_HEAD' to the original state of HEAD so a problematic merge can be removed by using 'git reset ORIG_HEAD'.

Note: from here

HEAD is a moving pointer. Sometimes it means the current branch, sometimes it doesn't.

So HEAD is NOT a synonym for "current branch" everywhere already.

HEAD means "current" everywhere in git, but it does not necessarily mean "current branch" (i.e. detached HEAD).

But it almost always means the "current commit".
It is the commit "git commit" builds on top of, and "git diff --cached" and "git status" compare against.
It means the current branch only in very limited contexts (exactly when we want a branch name to operate on --- resetting and growing the branch tip via commit/rebase/etc.).

Reflog is a vehicle to go back in time and time machines have interesting interaction with the notion of "current".

HEAD@{5.minutes.ago} could mean "dereference HEAD symref to find out what branch we are on RIGHT NOW, and then find out where the tip of that branch was 5 minutes ago".
Alternatively it could mean "what is the commit I would have referred to as HEAD 5 minutes ago, e.g. if I did "git show HEAD" back then".

git1.8.4 (July 2013) introduces introduced a new notation!
(Actually, it will be for 1.8.5, Q4 2013: reintroduced with commit 9ba89f4), by Felipe Contreras.

Instead of typing four capital letters "HEAD", you can say "@" now,
e.g. "git log @".

See commit cdfd948

Typing 'HEAD' is tedious, especially when we can use '@' instead.

The reason for choosing '@' is that it follows naturally from the ref@op syntax (e.g. HEAD@{u}), except we have no ref, and no operation, and when we don't have those, it makes sens to assume 'HEAD'.

So now we can use 'git show @~1', and all that goody goodness.

Until now '@' was a valid name, but it conflicts with this idea, so let's make it invalid. Probably very few people, if any, used this name.

Drag the constraint into your VC as an IBOutlet. Then you can change its associated value (and other properties; check the documentation):

@IBOutlet myConstraint : NSLayoutConstraint!
@IBOutlet myView : UIView!

func updateConstraints() {
    // You should handle UI updates on the main queue, whenever possible
    DispatchQueue.main.async {
        self.myConstraint.constant = 10
        self.myView.layoutIfNeeded()
    }
}

You can do this if you use an <a> tag instead of a button. I know it's not exactly what you asked for, but it might give you some other options if you cannot find a solution to this:

Just to add on these answers is that, mod_php is the oldest and slowest method available in HTTPD server to use PHP. It is not recommended, unless you are running old versions of Apache HTTPD and PHP. php-fpm and proxy_cgi are the preferred methods.

Place a breakpoint on the ending brace of main(). It will get tripped even with multiple return statements. The only downside is that a call to exit() won't be caught.

If you're not debugging, follow the advice in Zoidberg's answer and start your program with Ctrl+F5 instead of just F5.

I was struggling with this for a few days until I chanced on the issue when I had to build a new Dropdown. I had several DropDownList controls and attempted to get validation working with no luck. One was databound and the other was filled from the aspx page. I needed to drop the databound one and add a second manual list. In my case Validators failed if you built a dropdown like this and looked at any value (0 or -1) for either a required or compare validator:

<asp:DropDownList ID="DDL_Reason" CssClass="inputDropDown" runat="server">
<asp:ListItem>--Select--</asp:ListItem>                                                                                                
<asp:ListItem>Expired</asp:ListItem>                                                                                                
<asp:ListItem>Lost/Stolen</asp:ListItem>                                                                                                
<asp:ListItem>Location Change</asp:ListItem>                                                                                            
</asp:DropDownList>

However adding the InitialValue like this worked instantly for a compare Validator.

<asp:ListItem Text="-- Select --" Value="-1"></asp:ListItem>

I didn't make any workaround. I've just attached document:click on my toggle function as follow :

    @Directive({
      selector: '[appDropDown]'
    })
    export class DropdownDirective implements OnInit {

      @HostBinding('class.open') isOpen: boolean;

      constructor(private elemRef: ElementRef) { }

      ngOnInit(): void {
        this.isOpen = false;
      }

      @HostListener('document:click', ['$event'])
      @HostListener('document:touchstart', ['$event'])
      toggle(event) {
        if (this.elemRef.nativeElement.contains(event.target)) {
          this.isOpen = !this.isOpen;
        } else {
          this.isOpen = false;
      }
    }

So, when I am outside my directive, I close the dropdown.

The recommended way to write validation and authorization logic is to put that logic in separate request classes. This way your controller code will remain clean.

You can create a request class by executing php artisan make:request SomeRequest.

In each request class's rules() method define your validation rules:

//SomeRequest.php
public function rules()
{
   return [
    "name"    => [
          'required',
          'array', // input must be an array
          'min:3'  // there must be three members in the array
    ],
    "name.*"  => [
          'required',
          'string',   // input must be of type string
          'distinct', // members of the array must be unique
          'min:3'     // each string must have min 3 chars
    ]
  ];
}

In your controller write your route function like this:

// SomeController.php
public function store(SomeRequest $request) 
{
  // Request is already validated before reaching this point.
  // Your controller logic goes here.
}

public function update(SomeRequest $request)
{
  // It isn't uncommon for the same validation to be required
  // in multiple places in the same controller. A request class
  // can be beneficial in this way.
}

Each request class comes with pre- and post-validation hooks/methods which can be customized based on business logic and special cases in order to modify the normal behavior of request class.

You may create parent request classes for similar types of requests (e.g. web and api) requests and then encapsulate some common request logic in these parent classes.

One solution can be using pool of clients like the following:

const { Pool } = require('pg');
var config = {
    user: 'foo', 
    database: 'my_db', 
    password: 'secret', 
    host: 'localhost', 
    port: 5432, 
    max: 10, // max number of clients in the pool
    idleTimeoutMillis: 30000
};
const pool = new Pool(config);
pool.on('error', function (err, client) {
    console.error('idle client error', err.message, err.stack);
});
pool.query('SELECT $1::int AS number', ['2'], function(err, res) {
    if(err) {
        return console.error('error running query', err);
    }
    console.log('number:', res.rows[0].number);
});

You can see more details on this resource.

You can do this:

DB::transaction(function() {
      //
});

Everything inside the Closure executes within a transaction. If an exception occurs it will rollback automatically.

Faced the same Issue in MI devices and figured out the problem by following these Steps :

1) Go to Setting

2) Click on Additional Settings

3) Click on Developer Options

4) Click toggle of Install via USB to enable it

and the issue will be resolved.

Unfortunately you can't declare database names with a variable in that format.

For what you're trying to accomplish, you're going to need to wrap your statements within an EXEC() statement. So you'd have something like:

DECLARE @Sql varchar(max) ='CREATE DATABASE ' + @DBNAME

Then call

EXECUTE(@Sql) or sp_executesql(@Sql)

to execute the sql string.

This will remove your colour as well as the underline that anchor tag exists with

a {
    text-decoration: none ;
}

a:hover {
    color:white;
    text-decoration:none;
    cursor:pointer;
}

Well, base on your code, you would put onkeyup=sum() in each text box txt1 and txt2

If you want to change the card background color, use:

app:cardBackgroundColor="@somecolor"

like this:

<android.support.v7.widget.CardView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:cardBackgroundColor="@color/white">

</android.support.v7.widget.CardView>

Edit: As pointed by @imposible, you need to include

xmlns:app="http://schemas.android.com/apk/res-auto"

in your root XML tag in order to make this snippet function

Try this...

<script type="text/javascript">
      $("#form_oferta").submit(function(event) 
      {
           var myData = $( form ).serialize(); 
           $.ajax({
                type: "POST", 
                contentType:attr( "enctype", "multipart/form-data" ),
                url: " URL Goes Here ",  
                data: myData,  
                success: function( data )  
                {
                     alert( data );
                }
           });
           return false;  
      });
</script>

Here the contentType is specified as multipart/form-data as we do in the form tag, this will work to upload simple file On server side you just need to write simple file upload code to handle this request with echoing message you want to show to user as a response.

You have to modify your regex in the following way

pat = re.compile("^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$")

that's because . is a wildcard that stands for "every character"

To add to the other answers, here are the variable list from Python Documentation.

Directive   Meaning Notes

%a  Locale’s abbreviated weekday name.   
%A  Locale’s full weekday name.  
%b  Locale’s abbreviated month name.     
%B  Locale’s full month name.    
%c  Locale’s appropriate date and time representation.   
%d  Day of the month as a decimal number [01,31].    
%H  Hour (24-hour clock) as a decimal number [00,23].    
%I  Hour (12-hour clock) as a decimal number [01,12].    
%j  Day of the year as a decimal number [001,366].   
%m  Month as a decimal number [01,12].   
%M  Minute as a decimal number [00,59].  
%p  Locale’s equivalent of either AM or PM. (1)
%S  Second as a decimal number [00,61]. (2)
%U  Week number of the year (Sunday as the first day of the week) as a decimal number [00,53]. All days in a new year preceding the first Sunday are considered to be in week 0.    (3)
%w  Weekday as a decimal number [0(Sunday),6].   
%W  Week number of the year (Monday as the first day of the week) as a decimal number [00,53]. All days in a new year preceding the first Monday are considered to be in week 0.    (3)
%x  Locale’s appropriate date representation.    
%X  Locale’s appropriate time representation.    
%y  Year without century as a decimal number [00,99].    
%Y  Year with century as a decimal number.   
%z  Time zone offset indicating a positive or negative time difference from UTC/GMT of the form +HHMM or -HHMM, where H represents decimal hour digits and M represents decimal minute digits [-23:59, +23:59].  
%Z  Time zone name (no characters if no time zone exists).   
%%  A literal '%' character.     

The optional SECOND argument is the index, starting at 0. So to output the index and total length of an array called 'some_list':

<div>Total Length: {{some_list.length}}</div>
<div v-for="(each, i) in some_list">
  {{i + 1}} : {{each}}
</div>

If instead of a list, you were looping through an object, then the second argument is key of the key/value pair. So for the object 'my_object':

var an_id = new Vue({
  el: '#an_id',
  data: {
    my_object: {
        one: 'valueA',
        two: 'valueB'
    }
  }
})

The following would print out the key : value pairs. (you can name 'each' and 'i' whatever you want)

<div id="an_id">
  <span v-for="(each, i) in my_object">
    {{i}} : {{each}}<br/>
  </span>
</div>

I ran into this as well - I did all of my development on a Lenovo IdeaTab A2107A-F and could run development builds on it, and even release signed APKs (installed with adb install) with no issues. Once it was published in Alpha test mode and available on Google Play I received the "incompatible with your device" error message.

It turns out I had placed in my AndroidManifest.xml the following from a tutorial:

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<uses-permission android:name="android.permission.CAMERA" />

Well, the Lenovo IdeaTab A2107A-F doesn't have an autofocusing camera on it (which I learned from http://www.phonearena.com/phones/Lenovo-IdeaTab-A2107_id7611, under Cons: lacks autofocus camera). Regardless of whether I was using that feature, Google Play said no. Once that was removed I rebuilt my APK, uploaded it to Google Play, and sure enough my IdeaTab was now in the compatible devices list.

So, double-check every <uses-feature> and if you've been doing some copy-paste from the web check again. Odds are you requested some feature you aren't even using.

Use the StringFormat property (or ContentStringFormat on ContentControl and its derivatives, e.g. Label).

<TextBlock Text="{Binding Date, StringFormat={}{0:d}}" />

Note the {} prior to the standard String.Format positional argument notation allows the braces to be escaped in the markup extension language.

The below code works for me, for both accessing and changing a pixel value.

For accessing pixel's channel value :

for (int i = 0; i < image.cols; i++) {
    for (int j = 0; j < image.rows; j++) {
        Vec3b intensity = image.at<Vec3b>(j, i);
        for(int k = 0; k < image.channels(); k++) {
            uchar col = intensity.val[k]; 
        }   
    }
}

For changing a pixel value of a channel :

uchar pixValue;
for (int i = 0; i < image.cols; i++) {
    for (int j = 0; j < image.rows; j++) {
        Vec3b &intensity = image.at<Vec3b>(j, i);
        for(int k = 0; k < image.channels(); k++) {
            // calculate pixValue
            intensity.val[k] = pixValue;
        }
     }
}

If you have a CSV file with single or even multiple columns, you can do these line by line "diff" operations using the sqlite3 embedded db. It comes with python, so should be available on most linux/macs. You can script the sqlite3 commands on the bash shell without needing to write python.

1. Create your a.csv and b.csv files
2. Ensure sqlite3 is installed using the command "sqlite3 -help"
3. Run the below commands directly on the Linux/Mac shell (or put it in a script)

echo "
.mode csv
.import a.csv atable
.import b.csv btable
create table result as select * from atable EXCEPT select * from btable;
.output result.csv
select * from result ;
.quit
" | sqlite3 temp.db

Note : Ensure there is a newline for each of the sqlite3 commands.

How it works

1. Import the 2 csvs into "atable" and "btable" respectively.
2. Use the "except" sql operator to select the data available in "atable" but missing in "btable". Create a "result" table using the select query statement
3. Output the result table to result.csv by running "select * from result;"

If you need to operate on specific columns, sqlite3 or any db is the way to go.

I have tried diff'ing on multiple GB files using the builtin diff and comm tools. Sqlite beats linux utilities by a mile.

A very easy to use service is provided by ws.geonames.org. Here's an example URL:

http://ws.geonames.org/countryCode?lat=43.7534932&lng=28.5743187&type=JSON

And here's some (jQuery) code which I've added to your code:

if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(function(position) {
        $.getJSON('http://ws.geonames.org/countryCode', {
            lat: position.coords.latitude,
            lng: position.coords.longitude,
            type: 'JSON'
        }, function(result) {
            alert('Country: ' + result.countryName + '\n' + 'Code: ' + result.countryCode);
        });
    });
}?

If you are using ASP.NET MVC – you do not need an additional HTTP handler and some modifications of the web.config file. All you need – just to add some simple action in a Home/Common controller:

[HttpPost]
public JsonResult KeepSessionAlive() {
    return new JsonResult {Data = "Success"};
}

, write a piece of JavaScript code like this one (I have put it in one of site’s JavaScript file):

var keepSessionAlive = false;
var keepSessionAliveUrl = null;

function SetupSessionUpdater(actionUrl) {
    keepSessionAliveUrl = actionUrl;
    var container = $("#body");
    container.mousemove(function () { keepSessionAlive = true; });
    container.keydown(function () { keepSessionAlive = true; });
    CheckToKeepSessionAlive();
}

function CheckToKeepSessionAlive() {
    setTimeout("KeepSessionAlive()", 5*60*1000);
}

function KeepSessionAlive() {
    if (keepSessionAlive && keepSessionAliveUrl != null) {
        $.ajax({
            type: "POST",
            url: keepSessionAliveUrl,
            success: function () { keepSessionAlive = false; }
        });
    }
    CheckToKeepSessionAlive();
}

, and initialize this functionality by calling a JavaScript function:

SetupSessionUpdater('/Home/KeepSessionAlive');

Please note! I have implemented this functionality only for authorized users (there is no reason to keep session state for guests in most cases) and decision to keep session state active is not only based on – is browser open or not, but authorized user must do some activity on the site (move a mouse or type some key).

Use doubleval(). But be very careful about using decimals in financial transactions, and validate that user input very carefully.

For .net 2.0 this works. It DOES compile both in the same project if you create sub directories of in app code with the related language code. As of yet, I am looking for whether this should work in 3.5 or not though.

You are checking Parent properties for null in your delegate. The same should work with lambda expressions too.

List<AnalysisObject> analysisObjects = analysisObjectRepository
        .FindAll()
        .Where(x => 
            (x.ID == packageId) || 
            (x.Parent != null &&
                (x.Parent.ID == packageId || 
                (x.Parent.Parent != null && x.Parent.Parent.ID == packageId)))
        .ToList();

Here's what I did that that brought the authorization prompt and made my device appear. I used a Samsung Galaxy s7 edge.

1. Enable developer mode and USB debugging on your device.

2. Revoke the USB debugging authorization

3. Plug your phone to computer via USB.

4. Drag notification panel and select "Software Installation" as shown in the image below

   

5. This will begin installing USB driver and the prompt for USB debugging authorization will show.

First of all wrap the src in {}

Then if using Webpack; Instead of: <img src={"./logo.jpeg"} />

You may need to use require:

<img src={require('./logo.jpeg')} />

Another option would be to first import the image as such:

import logo from './logo.jpeg'; // with import

or ...

const logo = require('./logo.jpeg); // with require

then plug it in...

<img src={logo} />

I'd recommend this option especially if you're reusing the image source.

Simply remove the .value from your code.

Set envFrmwrkPath = ActiveSheet.Range("D6").Value

instead of this, use:

Set envFrmwrkPath = ActiveSheet.Range("D6")

Django has some documentation about that on their website, see: Saving changes to objects. To summarize:

.. to save changes to an object that's already in the database, use save().

It is very simple:

1. To check the current status of any file in the current dir, whether it is staged or not:

   git status

2. Staging any files:

   git add . for all files in the current directory

   git add <filename> for specific file

3. Unstaging the file:

   git restore --staged <filename>

After typing "prop" + Tab + Tab as suggested by Amra, you can immediately type the property's type (which will replace the default int), type another tab and type the property name (which will replace the default MyProperty). Finish by pressing Enter.

Here's a fairly simple way to achieve it by enclosing both the magnifying glass icon and the input field inside a div with relative positioning.

Absolute positioning is applied to the icon, which takes it out of the normal document layout flow. The icon is then positioned inside the input. Left padding is applied to the input so that the user's input appears to the right of the icon.

Note that this example places the magnifying glass icon on the left instead of the right. This is recommended when using <input type="search"> as Chrome adds an X button in the right side of the searchbox. If we placed the icon there it would overlay the X button and look fugly.

Here is the needed Bootstrap markup.

<div class="position-relative">
    <i class="fa fa-search position-absolute"></i>
    <input class="form-control" type="search">
</div>

...and a couple CSS classes for the things which I couldn't do with Bootstrap classes:

i {
    font-size: 1rem;
    color: #333;
    top: .75rem;
    left: .75rem
}

input {
    padding-left: 2.5rem;
}

You may have to fiddle with the values for top, left, and padding-left.

I am not sure why anyone hasn't suggested http://gitblit.com. Pure java based solution, allow HTTP protocol and really easy to setup.

Others have provided answers for how to change the title size, but as for the axes tick label size, you can also use the set_tick_params method.

E.g., to make the x-axis tick label size small:

ax.xaxis.set_tick_params(labelsize='small')

or, to make the y-axis tick label large:

ax.yaxis.set_tick_params(labelsize='large')

You can also enter the labelsize as a float, or any of the following string options: 'xx-small', 'x-small', 'small', 'medium', 'large', 'x-large', or 'xx-large'.

I've implemented and tested this one; it should cover most bases:

public static <T> List<T> safeSubList(List<T> list, int fromIndex, int toIndex) {
    int size = list.size();
    if (fromIndex >= size || toIndex <= 0 || fromIndex >= toIndex) {
        return Collections.emptyList();
    }

    fromIndex = Math.max(0, fromIndex);
    toIndex = Math.min(size, toIndex);

    return list.subList(fromIndex, toIndex);
}

import java.util.*;

class GetCurrentmonth
{
    public static void main(String args[])
    {
        int month;
        GregorianCalendar date = new GregorianCalendar();      
        month = date.get(Calendar.MONTH);
        month = month+1;
        System.out.println("Current month is  " + month);
    }
}

Yes, this is confusing...

According to this blog post, it looks like this is an omission from WPF.

To make it work you need to use a style:

    <Border Name="ClearButtonBorder" Grid.Column="1" CornerRadius="0,3,3,0">
        <Border.Style>
            <Style>
                <Setter Property="Border.Background" Value="Blue"/>
                <Style.Triggers>
                    <Trigger Property="Border.IsMouseOver" Value="True">
                        <Setter Property="Border.Background" Value="Green" />
                    </Trigger>
                </Style.Triggers>
            </Style>
        </Border.Style>
        <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="X" />
    </Border>

I guess this problem isn't that common as most people tend to factor out this sort of thing into a style, so it can be used on multiple controls.

What about pymysql? It's pure Python, and I've used it on Windows with considerable success, bypassing the difficulties of compiling and installing mysql-python.

1. Upload setup.py to drive.
2. Mount the drive.
3. Get the path of setup.py.
4. !python PATH install.

armhf stands for "arm hard float", and is the name given to a debian port for arm processors (armv7+) that have hardware floating point support.

On the beaglebone black, for example:

:~$ dpkg --print-architecture
armhf

Although other commands (such as uname -a or arch) will just show armv7l

:~$ cat /proc/cpuinfo 
processor       : 0
model name      : ARMv7 Processor rev 2 (v7l)
BogoMIPS        : 995.32
Features        : half thumb fastmult vfp edsp thumbee neon vfpv3 tls
...

The vfpv3 listed under Features is what refers to the floating point support.

Incidentally, armhf, if your processor supports it, basically supersedes Raspbian, which if I understand correctly was mainly a rebuild of armhf with work arounds to deal with the lack of floating point support on the original raspberry pi's. Nowdays, of course, there's a whole ecosystem build up around Raspbian, so they're probably not going to abandon it. However, this is partly why the beaglebone runs straight debian, and that's ok even if you're used to Raspbian, unless you want some of the special included non-free software such as Mathematica.

You can use the datetime module for working with dates and times in Python. The strftime method allows you to produce string representation of dates and times with a format you specify.

You have more static resources that the cache has room for. You can do one of the following:

• Increase the size of the cache
• Decrease the TTL for the cache
• Disable caching

For more details see the documentation for these configuration options.

You can use mt_rand()

$random = $ran[mt_rand(0, count($ran) - 1)];

This comes in handy as a function as well if you need the value

function random_value($array, $default=null)
{
    $k = mt_rand(0, count($array) - 1);
    return isset($array[$k])? $array[$k]: $default;
}

If you use jquery, it can be done by using $(window).height();

<iframe src="html_intro.asp" width="100%" class="myIframe">
<p>Hi SOF</p>
</iframe>

<script type="text/javascript" language="javascript"> 
$('.myIframe').css('height', $(window).height()+'px');
</script>

Try something like this. Like in this format it will return you a continuous line like you have successfully enquired about this property:

"message": f'You have successfully inquired about '
           f'{enquiring_property.title} Property owned by '
           f'{enquiring_property.client}'

Now a days phonegap and cordova is owned by Adobe. Only name conversation was different. For install plugin functionality , we should use same command for phonegap and cordova too.

Command : cordova plugin add cordova-plugin-photo-library

Here,

• cordova - keyword for initiator
• plugin - initialize a plugin
• cordova plugin photo library - plugin name.

You can also find more plugin from https://cordova.apache.org/docs/en/latest/

I've always tested to find the MAX string length of an encrypted string and set that as the character length of a VARCHAR type. Depending on how many records you're going to have, it could really help the database size.

Based on the syntax provided

 Select * Where Amount = min(Amount)

You could do using:

 library(sqldf)

Using @Kara Woo's example df

  sqldf("select * from df where Amount in (select min(Amount) from df)")
  #Name Amount
 #1    B    120
 #2    E    120

In my case, this error started appearing randomly and wouldn't go away even after setting a timeout of 30000. Simply ending the process in the terminal and re-running the tests resolved the issue for me. I have also removed the timeout and tests are still passing again.

string = "removeTHISplease";
result = string.replace('THIS','');

I think replace do the same thing like a some own function. For me this works.

I wrestled quite a while with the proper syntax for CREATE TEMPORARY TABLE SELECT. Having figured out a few things, I wanted to share the answers with the rest of the community.

Basic information about the statement is available at the following MySQL links:

CREATE TABLE SELECT and CREATE TABLE.

At times it can be daunting to interpret the spec. Since most people learn best from examples, I will share how I have created a working statement, and how you can modify it to work for you.

1. Add multiple indexes

   This statement shows how to add multiple indexes (note that index names - in lower case - are optional):

   CREATE TEMPORARY TABLE core.my_tmp_table 
   (INDEX my_index_name (tag, time), UNIQUE my_unique_index_name (order_number))
   SELECT * FROM core.my_big_table
   WHERE my_val = 1
   

2. Add a new primary key:

   CREATE TEMPORARY TABLE core.my_tmp_table 
   (PRIMARY KEY my_pkey (order_number),
   INDEX cmpd_key (user_id, time))
   SELECT * FROM core.my_big_table
   

3. Create additional columns

   You can create a new table with more columns than are specified in the SELECT statement. Specify the additional column in the table definition. Columns specified in the table definition and not found in select will be first columns in the new table, followed by the columns inserted by the SELECT statement.

   CREATE TEMPORARY TABLE core.my_tmp_table 
   (my_new_id BIGINT NOT NULL AUTO_INCREMENT,  
   PRIMARY KEY my_pkey (my_new_id), INDEX my_unique_index_name (invoice_number))
   SELECT * FROM core.my_big_table
   

4. Redefining data types for the columns from SELECT

   You can redefine the data type of a column being SELECTed. In the example below, column tag is a MEDIUMINT in core.my_big_table and I am redefining it to a BIGINT in core.my_tmp_table.

   CREATE TEMPORARY TABLE core.my_tmp_table 
   (tag BIGINT,
   my_time DATETIME,  
   INDEX my_unique_index_name (tag) )
   SELECT * FROM core.my_big_table
   

5. Advanced field definitions during create

   All the usual column definitions are available as when you create a normal table. Example:

   CREATE TEMPORARY TABLE core.my_tmp_table 
   (id INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
   value BIGINT UNSIGNED NOT NULL DEFAULT 0 UNIQUE,
   location VARCHAR(20) DEFAULT "NEEDS TO BE SET",
   country CHAR(2) DEFAULT "XX" COMMENT "Two-letter country code",  
   INDEX my_index_name (location))
   ENGINE=MyISAM 
   SELECT * FROM core.my_big_table
   

You are trying to read the set value before Angular is done assigning.

Demo:

var testController = function ($scope, $timeout) {
    console.log('test');
    $timeout(function(){
        console.log($scope.testInput);
    },1000);
}

Ideally you should use $watch as suggested by @Beterraba to get rid of the timer:

var testController = function ($scope) {
    console.log('test');
    $scope.$watch("testInput", function(){
        console.log($scope.testInput);
    });
}

1. Storing JSON in database violates the first normal form.

   The best thing you can do is to normalize and store features in another table. Then you will be able to use a much better looking and performing query with joins. Your JSON even resembles the table.

2. Mysql 5.7 has builtin JSON functionality:
   http://mysqlserverteam.com/mysql-5-7-lab-release-json-functions-part-2-querying-json-data/

3. Correct pattern is:

   WHERE  `attribs_json` REGEXP '"1":{"value":[^}]*"3"[^}]*}'
   

   [^}] will match any character except }

Please set your form action attribute as below it will solve your problem.

<form name="addProductForm" id="addProductForm" action="javascript:;" enctype="multipart/form-data" method="post" accept-charset="utf-8">

jQuery code:

$(document).ready(function () {
    $("#addProductForm").submit(function (event) {

        //disable the default form submission
        event.preventDefault();
        //grab all form data  
        var formData = $(this).serialize();

        $.ajax({
            url: 'addProduct.php',
            type: 'POST',
            data: formData,
            async: false,
            cache: false,
            contentType: false,
            processData: false,
            success: function () {
                alert('Form Submitted!');
            },
            error: function(){
                alert("error in ajax form submission");
            }
        });

        return false;
    });
});

It is possible to view a html file from terminal using lynx or links. But none of those browswers support the onload javascript feature. By using lynx or links you will have to actively click the submit button.

You could fill the dependend cell (D2) by a User Defined Function (VBA Macro Function) that takes the value of the C2-Cell as input parameter, returning the current date as ouput.

Having C2 as input parameter for the UDF in D2 tells Excel that it needs to reevaluate D2 everytime C2 changes (that is if auto-calculation of formulas is turned on for the workbook).

EDIT:

Here is some code:

For the UDF:

    Public Function UDF_Date(ByVal data) As Date

        UDF_Date = Now()

    End Function

As Formula in D2:

=UDF_Date(C2)

You will have to give the D2-Cell a Date-Time Format, or it will show a numeric representation of the date-value.

And you can expand the formula over the desired range by draging it if you keep the C2 reference in the D2-formula relative.

Note: This still might not be the ideal solution because every time Excel recalculates the workbook the date in D2 will be reset to the current value. To make D2 only reflect the last time C2 was changed there would have to be some kind of tracking of the past value(s) of C2. This could for example be implemented in the UDF by providing also the address alonside the value of the input parameter, storing the input parameters in a hidden sheet, and comparing them with the previous values everytime the UDF gets called.

Addendum:

Here is a sample implementation of an UDF that tracks the changes of the cell values and returns the date-time when the last changes was detected. When using it, please be aware that:

• The usage of the UDF is the same as described above.

• The UDF works only for single cell input ranges.

• The cell values are tracked by storing the last value of cell and the date-time when the change was detected in the document properties of the workbook. If the formula is used over large datasets the size of the file might increase considerably as for every cell that is tracked by the formula the storage requirements increase (last value of cell + date of last change.) Also, maybe Excel is not capable of handling very large amounts of document properties and the code might brake at a certain point.

• If the name of a worksheet is changed all the tracking information of the therein contained cells is lost.

• The code might brake for cell-values for which conversion to string is non-deterministic.

• The code below is not tested and should be regarded only as proof of concept. Use it at your own risk.

  Public Function UDF_Date(ByVal inData As Range) As Date
  
      Dim wb As Workbook
      Dim dProps As DocumentProperties
      Dim pValue As DocumentProperty
      Dim pDate As DocumentProperty
      Dim sName As String
      Dim sNameDate As String
  
      Dim bDate As Boolean
      Dim bValue As Boolean
      Dim bChanged As Boolean
  
      bDate = True
      bValue = True
  
      bChanged = False
  
  
      Dim sVal As String
      Dim dDate As Date
  
      sName = inData.Address & "_" & inData.Worksheet.Name
      sNameDate = sName & "_dat"
  
      sVal = CStr(inData.Value)
      dDate = Now()
  
      Set wb = inData.Worksheet.Parent
  
      Set dProps = wb.CustomDocumentProperties
  
  On Error Resume Next
  
      Set pValue = dProps.Item(sName)
  
      If Err.Number <> 0 Then
          bValue = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bValue Then
          bChanged = True
          Set pValue = dProps.Add(sName, False, msoPropertyTypeString, sVal)
      Else
          bChanged = pValue.Value <> sVal
          If bChanged Then
              pValue.Value = sVal
          End If
      End If
  
  On Error Resume Next
  
      Set pDate = dProps.Item(sNameDate)
  
      If Err.Number <> 0 Then
          bDate = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bDate Then
          Set pDate = dProps.Add(sNameDate, False, msoPropertyTypeDate, dDate)
      End If
  
      If bChanged Then
          pDate.Value = dDate
      Else
          dDate = pDate.Value
      End If
  
  
      UDF_Date = dDate
   End Function
  

Make the insertion of the date conditional upon the range.

This has an advantage of not changing the dates unless the content of the cell is changed, and it is in the range C2:C2, even if the sheet is closed and saved, it doesn't recalculate unless the adjacent cell changes.

Did you setup your project to be compiled with 1.4 compliance? If so, do what krock said. Or to be more exact you need to select the J2SE-1.4 execution environment and check one of the installed JRE that you want to use in 1.4 compliance mode; most likely you'll have a 1.6 JRE installed, just check that one. Or install a 1.4 JRE if you have a setup kit, and use that one.

Otherwise go to your Eclipse preferences, Java -> Compiler and check if the compliance is set to 1.4. If it is change it back to 1.6. If it's not go to the project properties, and check if it has project specific settings. Go to Java Compiler, and uncheck that if you want to use the general eclipse preferences. Or set the project specific settings to 1.6, so that it's always 1.6 regardless of eclipse preferences.

The following main steps are required to achieve a secured connection from Certification Authorities which are not considered as trusted by the android platform.

As requested by many users, I've mirrored the most important parts from my blog article here:

1. Grab all required certificates (root and any intermediate CA’s)
2. Create a keystore with keytool and the BouncyCastle provider and import the certs
3. Load the keystore in your android app and use it for the secured connections (I recommend to use the Apache HttpClient instead of the standard java.net.ssl.HttpsURLConnection (easier to understand, more performant)

Grab the certs

You have to obtain all certificates that build a chain from the endpoint certificate the whole way up to the Root CA. This means, any (if present) Intermediate CA certs and also the Root CA cert. You don’t need to obtain the endpoint certificate.

Create the keystore

Download the BouncyCastle Provider and store it to a known location. Also ensure that you can invoke the keytool command (usually located under the bin folder of your JRE installation).

Now import the obtained certs (don’t import the endpoint cert) into a BouncyCastle formatted keystore.

I didn’t test it, but I think the order of importing the certificates is important. This means, import the lowermost Intermediate CA certificate first and then all the way up to the Root CA certificate.

With the following command a new keystore (if not already present) with the password mysecret will be created and the Intermediate CA certificate will be imported. I also defined the BouncyCastle provider, where it can be found on my file system and the keystore format. Execute this command for each certificate in the chain.

keytool -importcert -v -trustcacerts -file "path_to_cert/interm_ca.cer" -alias IntermediateCA -keystore "res/raw/mykeystore.bks" -provider org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath "path_to_bouncycastle/bcprov-jdk16-145.jar" -storetype BKS -storepass mysecret

Verify if the certificates were imported correctly into the keystore:

keytool -list -keystore "res/raw/mykeystore.bks" -provider org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath "path_to_bouncycastle/bcprov-jdk16-145.jar" -storetype BKS -storepass mysecret

Should output the whole chain:

RootCA, 22.10.2010, trustedCertEntry, Thumbprint (MD5): 24:77:D9:A8:91:D1:3B:FA:88:2D:C2:FF:F8:CD:33:93
IntermediateCA, 22.10.2010, trustedCertEntry, Thumbprint (MD5): 98:0F:C3:F8:39:F7:D8:05:07:02:0D:E3:14:5B:29:43

Now you can copy the keystore as a raw resource in your android app under res/raw/

Use the keystore in your app

First of all we have to create a custom Apache HttpClient that uses our keystore for HTTPS connections:

import org.apache.http.*

public class MyHttpClient extends DefaultHttpClient {

    final Context context;

    public MyHttpClient(Context context) {
        this.context = context;
    }

    @Override
    protected ClientConnectionManager createClientConnectionManager() {
        SchemeRegistry registry = new SchemeRegistry();
        registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
        // Register for port 443 our SSLSocketFactory with our keystore
        // to the ConnectionManager
        registry.register(new Scheme("https", newSslSocketFactory(), 443));
        return new SingleClientConnManager(getParams(), registry);
    }

    private SSLSocketFactory newSslSocketFactory() {
        try {
            // Get an instance of the Bouncy Castle KeyStore format
            KeyStore trusted = KeyStore.getInstance("BKS");
            // Get the raw resource, which contains the keystore with
            // your trusted certificates (root and any intermediate certs)
            InputStream in = context.getResources().openRawResource(R.raw.mykeystore);
            try {
                // Initialize the keystore with the provided trusted certificates
                // Also provide the password of the keystore
                trusted.load(in, "mysecret".toCharArray());
            } finally {
                in.close();
            }
            // Pass the keystore to the SSLSocketFactory. The factory is responsible
            // for the verification of the server certificate.
            SSLSocketFactory sf = new SSLSocketFactory(trusted);
            // Hostname verification from certificate
            // http://hc.apache.org/httpcomponents-client-ga/tutorial/html/connmgmt.html#d4e506
            sf.setHostnameVerifier(SSLSocketFactory.STRICT_HOSTNAME_VERIFIER);
            return sf;
        } catch (Exception e) {
            throw new AssertionError(e);
        }
    }
}

We have created our custom HttpClient, now we can use it for secure connections. For example when we make a GET call to a REST resource:

// Instantiate the custom HttpClient
DefaultHttpClient client = new MyHttpClient(getApplicationContext());
HttpGet get = new HttpGet("https://www.mydomain.ch/rest/contacts/23");
// Execute the GET call and obtain the response
HttpResponse getResponse = client.execute(get);
HttpEntity responseEntity = getResponse.getEntity();

That's it ;)

This error happen usually when tables in the query doesn't exist. Just check the table's spelling in the query, and it will work.

Initialization is not require in case of zero because default value of int in Java is zero. For values other than zero java.util.Arrays provides a number of options, simplest one is fill method.

int[] arr = new int[5];
Arrays.fill(arr, -1);
System.out.println(Arrays.toString(arr));  //[-1, -1, -1, -1, -1 ]

int [] arr = new int[5];
// fill value 1 from index 0, inclusive, to index 3, exclusive
Arrays.fill(arr, 0, 3, -1 )
System.out.println(Arrays.toString(arr)); // [-1, -1, -1, 0, 0]

We can also use Arrays.setAll() if we want to fill value on condition basis:

int[] array = new int[20];
Arrays.setAll(array, p -> p > 10 ? -1 : p);

int[] arr = new int[5];
Arrays.setAll(arr, i -> i);
System.out.println(Arrays.toString(arr));   // [0, 1, 2, 3, 4]

If someone is in search for a quick minimal solution,

import signal

# The code which crashes program on interruption

signal.signal(signal.SIGINT, call_this_function_if_interrupted)

# The code skipped if interrupted

None of the provided examples on here worked for me. They were either for Python 2 (uurllib2) or those for Python 3 return the error "ImportError: No module named request". I google the error message and it apparently requires me to install a the module - which is obviously unacceptable for such a simple task.

This code worked for me:

import json,urllib
data = urllib.urlopen("https://api.github.com/users?since=0").read()
d = json.loads(data)
print (d)

The accepted answer doesn't quite work when you have foreign key relationships. In that case you have to drop the constraints and recreate them. Below is a stored proc for doing that based on the answer here

You can use urllib2 as well:

import urllib2

req = urllib2.Request('http://www.python.org/fish.html')
try:
    resp = urllib2.urlopen(req)
except urllib2.HTTPError as e:
    if e.code == 404:
        # do something...
    else:
        # ...
except urllib2.URLError as e:
    # Not an HTTP-specific error (e.g. connection refused)
    # ...
else:
    # 200
    body = resp.read()

Note that HTTPError is a subclass of URLError which stores the HTTP status code.

This should work:

/^((?!PART).)*$/

If you only wanted to exclude it from the beginning of the line (I know you don't, but just FYI), you could use this:

/^(?!PART)/

Edit (by request): Why this pattern works

The (?!...) syntax is a negative lookahead, which I've always found tough to explain. Basically, it means "whatever follows this point must not match the regular expression /PART/." The site I've linked explains this far better than I can, but I'll try to break this down:

^         #Start matching from the beginning of the string.    
(?!PART)  #This position must not be followed by the string "PART".
.         #Matches any character except line breaks (it will include those in single-line mode).
$         #Match all the way until the end of the string.

The ((?!xxx).)* idiom is probably hardest to understand. As we saw, (?!PART) looks at the string ahead and says that whatever comes next can't match the subpattern /PART/. So what we're doing with ((?!xxx).)* is going through the string letter by letter and applying the rule to all of them. Each character can be anything, but if you take that character and the next few characters after it, you'd better not get the word PART.

The ^ and $ anchors are there to demand that the rule be applied to the entire string, from beginning to end. Without those anchors, any piece of the string that didn't begin with PART would be a match. Even PART itself would have matches in it, because (for example) the letter A isn't followed by the exact string PART.

Since we do have ^ and $, if PART were anywhere in the string, one of the characters would match (?=PART). and the overall match would fail. Hope that's clear enough to be helpful.

Are methods using FOR XML PATH like below really that slow? Itzik Ben-Gan writes that this method has good performance in his T-SQL Querying book (Mr. Ben-Gan is a trustworthy source, in my view).

create table #t (id int, name varchar(20))

insert into #t
values (1, 'Matt'), (1, 'Rocks'), (2, 'Stylus')

select  id
        ,Names = stuff((select ', ' + name as [text()]
        from #t xt
        where xt.id = t.id
        for xml path('')), 1, 2, '')
from #t t
group by id

Since AngularJS 1.5 we should use $onInit which is available on any AngularJS component. Taken from the component lifecycle documentation since v1.5 its the preffered way:

$onInit() - Called on each controller after all the controllers on an element have been constructed and had their bindings initialized (and before the pre & post linking functions for the directives on this element). This is a good place to put initialization code for your controller.

var myApp = angular.module('myApp',[]);
myApp.controller('MyCtrl', function ($scope) {

    //default state
    $scope.name = '';

    //all your init controller goodness in here
    this.$onInit = function () {
      $scope.name = 'Superhero';
    }
});

An advanced example of using component lifecycle:

The component lifecycle gives us the ability to handle component stuff in a good way. It allows us to create events for e.g. "init", "change" or "destroy" of an component. In that way we are able to manage stuff which is depending on the lifecycle of an component. This little example shows to register & unregister an $rootScope event listener $on. By knowing, that an event $on binded on $rootScope will not be undinded when the controller loses its reference in the view or getting destroyed we need to destroy a $rootScope.$on listener manually. A good place to put that stuff is $onDestroy lifecycle function of an component:

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

myApp.controller('MyCtrl', function ($scope, $rootScope) {

  var registerScope = null;

  this.$onInit = function () {
    //register rootScope event
    registerScope = $rootScope.$on('someEvent', function(event) {
        console.log("fired");
    });
  }

  this.$onDestroy = function () {
    //unregister rootScope event by calling the return function
    registerScope();
  }
});

You can also use query which is very readable in my opinion and straightforward to use:

import pandas as pd

df = pd.DataFrame({'A': [1, 2, 3, 4], 'B': [10, 20, 50, 80], 'C': [6, 7, 8, 9]})
df = df.set_index(['A', 'B'])

      C
A B    
1 10  6
2 20  7
3 50  8
4 80  9

For what you had in mind you can now simply do:

df.query('A == 1')

      C
A B    
1 10  6

You can also have more complex queries using and

df.query('A >= 1 and B >= 50')

      C
A B    
3 50  8
4 80  9

and or

df.query('A == 1 or B >= 50')

      C
A B    
1 10  6
3 50  8
4 80  9

You can also query on different index levels, e.g.

df.query('A == 1 or C >= 8')

will return

      C
A B    
1 10  6
3 50  8
4 80  9

If you want to use variables inside your query, you can use @:

b_threshold = 20
c_threshold = 8

df.query('B >= @b_threshold and C <= @c_threshold')

      C
A B    
2 20  7
3 50  8

Steve's reply is definitely the correct technique but it should be refactored so that your installpath variable is in a separate environment script where all such declarations are made.

Then all scripts source that script and should installpath change, you only need to change it in one location. Makes things more, er, futureproof. God I hate that word! (-:

BTW You should really refer to the variable using ${installpath} when using it in the way shown in your example:

. ${installpath}/incl.sh

If the braces are left out, some shells will try and expand the variable "installpath/incl.sh"!

If your array has static storage allocation, it is default initialized to zero. However, if the array has automatic storage allocation, then you can simply initialize all its elements to zero using an array initializer list which contains a zero.

// function scope
// this initializes all elements to 0
int arr[4] = {0};
// equivalent to
int arr[4] = {0, 0, 0, 0};

// file scope
int arr[4];
// equivalent to
int arr[4] = {0};

Please note that there is no standard way to initialize the elements of an array to a value other than zero using an initializer list which contains a single element (the value). You must explicitly initialize all elements of the array using the initializer list.

// initialize all elements to 4
int arr[4] = {4, 4, 4, 4};
// equivalent to
int arr[] = {4, 4, 4, 4};

In Swift 4.2 the notification names have moved to a different namespace. So now it's

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    addKeyboardListeners()
}


override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    NotificationCenter.default.removeObserver(self)
}


func addKeyboardListeners() {
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name: UIResponder.keyboardWillHideNotification, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name: UIResponder.keyboardWillShowNotification, object: nil)
}

@objc private extension WhateverTheClassNameIs {

    func keyboardWillShow(_ notification: Notification) {
        // Do something here.
    }

    func keyboardWillHide(_ notification: Notification) {
        // Do something here.
    }
}

Response you are getting is in object form i.e.

{ 
  "dstOffset" : 3600, 
  "rawOffset" : 36000, 
  "status" : "OK", 
  "timeZoneId" : "Australia/Hobart", 
  "timeZoneName" : "Australian Eastern Daylight Time" 
}

Replace below line of code :

List<Post> postsList = Arrays.asList(gson.fromJson(reader,Post.class))

with

Post post = gson.fromJson(reader, Post.class);

Once you set the app.config file, visual studio will generate a copy in the bin folder named App.exe.config. Copy this to the application directory during deployment. Sounds obvious but surprisingly a lot of people miss this step. WinForms developers are not used to config files :).

The python seaborn module is based on matplotlib, and produces a very nice heatmap.

Below is an implementation with seaborn, designed for the ipython/jupyter notebook.

import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
%matplotlib inline
# import the data directly into a pandas dataframe
nba = pd.read_csv("http://datasets.flowingdata.com/ppg2008.csv", index_col='Name  ')
# remove index title
nba.index.name = ""
# normalize data columns
nba_norm = (nba - nba.mean()) / (nba.max() - nba.min())
# relabel columns
labels = ['Games', 'Minutes', 'Points', 'Field goals made', 'Field goal attempts', 'Field goal percentage', 'Free throws made', 
          'Free throws attempts', 'Free throws percentage','Three-pointers made', 'Three-point attempt', 'Three-point percentage', 
          'Offensive rebounds', 'Defensive rebounds', 'Total rebounds', 'Assists', 'Steals', 'Blocks', 'Turnover', 'Personal foul']
nba_norm.columns = labels
# set appropriate font and dpi
sns.set(font_scale=1.2)
sns.set_style({"savefig.dpi": 100})
# plot it out
ax = sns.heatmap(nba_norm, cmap=plt.cm.Blues, linewidths=.1)
# set the x-axis labels on the top
ax.xaxis.tick_top()
# rotate the x-axis labels
plt.xticks(rotation=90)
# get figure (usually obtained via "fig,ax=plt.subplots()" with matplotlib)
fig = ax.get_figure()
# specify dimensions and save
fig.set_size_inches(15, 20)
fig.savefig("nba.png")

The output looks like this: I used the matplotlib Blues color map, but personally find the default colors quite beautiful. I used matplotlib to rotate the x-axis labels, as I couldn't find the seaborn syntax. As noted by grexor, it was necessary to specify the dimensions (fig.set_size_inches) by trial and error, which I found a bit frustrating.

As noted by Paul H, you can easily add the values to heat maps (annot=True), but in this case I didn't think it improved the figure. Several code snippets were taken from the excellent answer by joelotz.

I know this is an old post but I was looking up something similar... I think your issue was that when you use Now(), the output will be "6/20/2014"... This an issue for a file name as it has "/" in it. As you may know, you cannot use certain symbols in a file name.

Although there are some useful algorithmic explanations here, I think it may help to add some simple 'real life' reasoning as to why it works this way, which I have found useful when introducing the subject to young newcomers:

With something like 'range(1,10)' confusion can arise from thinking that pair of parameters represents the "start and end".

It is actually start and "stop".

Now, if it were the "end" value then, yes, you might expect that number would be included as the final entry in the sequence. But it is not the "end".

Others mistakenly call that parameter "count" because if you only ever use 'range(n)' then it does, of course, iterate 'n' times. This logic breaks down when you add the start parameter.

So the key point is to remember its name: "stop". That means it is the point at which, when reached, iteration will stop immediately. Not after that point.

So, while "start" does indeed represent the first value to be included, on reaching the "stop" value it 'breaks' rather than continuing to process 'that one as well' before stopping.

One analogy that I have used in explaining this to kids is that, ironically, it is better behaved than kids! It doesn't stop after it supposed to - it stops immediately without finishing what it was doing. (They get this ;) )

Another analogy - when you drive a car you don't pass a stop/yield/'give way' sign and end up with it sitting somewhere next to, or behind, your car. Technically you still haven't reached it when you do stop. It is not included in the 'things you passed on your journey'.

I hope some of that helps in explaining to Pythonitos/Pythonitas!

system("mkdir -p /tmp/a/b/c")

This is not, as you've titled it, a "JavaScript" question; it is a question regarding the design of jQuery.

jQuery and the previously linked citation from John Resig (in karim79's message) seem to be the source misunderstanding of how event handlers in general work.

Fact: An event handler that returns false prevents the default action for that event. It does not stop the event propagation. Event handlers have always worked this way, since the old days of Netscape Navigator.

The documentation from MDN explains how return false in an event handler works

What happens in jQuery is not the same as what happens with event handlers. DOM event listeners and MSIE "attached" events are a different matter altogether.

For further reading, see attachEvent on MSDN and the W3C DOM 2 Events documentation.

DataFrames are based on RDDs. RDDs are immutable structures and do not allow updating elements on-site. To change values, you will need to create a new DataFrame by transforming the original one either using the SQL-like DSL or RDD operations like map.

A highly recommended slide deck: Introducing DataFrames in Spark for Large Scale Data Science.

CSS was designed to affect presentation, not behaviour.

You could use some JavaScript.

document.links[0].onclick = function(event) {
   event.preventDefault();
};

XAMPP Apache + MariaDB + PHP + Perl (X -any OS)

By default your port is listing with 80.If you want you can change it to your desired port number in httpd.conf file.(If port 80 is already using with other app then you have to change it).

For example you changed port number 80 to 8090 then you can run as 'localhost:8090' or '127.0.0.1:8090'

You need to use custom comparator which will use compareToIgnoreCase, not compareTo.

The answer of this question depends on the number of items and their size and your budget. Depends on that we have following 3 cases:

1- The number of items and size of items in the table are not very much. then as Steffen Opel said you can Use Query rather than Scan to retrieve all items for user_id and then loop over all returned items and either facilitate DeleteItem or BatchWriteItem. But keep in mind you may burn a lot of throughput capacity here. For example, consider a situation where you need delete 1000 items from a DynamoDB table. Assume that each item is 1 KB in size, resulting in Around 1MB of data. This bulk-deleting task will require a total of 2000 write capacity units for query and delete. To perform this data load within 10 seconds (which is not even considered as fast in some applications), you would need to set the provisioned write throughput of the table to 200 write capacity units. As you can see its doable to use this way if its for less number of items or small size items.

2- We have a lot of items or very large items in the table and we can store them according to the time into different tables. Then as jonathan Said you can just delete the table. this is much better but I don't think it is matched with your case. As you want to delete all of users data no matter what is the time of creation of logs, so in this case you can't delete a particular table. if you wanna have a separate table for each user then I guess if number of users are high then its so expensive and it is not practical for your case.

3- If you have a lot of data and you can't divide your hot and cold data into different tables and you need to do large scale delete frequently then unfortunately DynamoDB is not a good option for you at all. It may become more expensive or very slow(depends on your budget). In these cases I recommend to find another database for your data.

You can make simple batch based on @mike-caron answer so you don't need to type every time whole robocopy command instead just input path to selected folder:

@echo off
ECHO What Directory would you like to empty?
ECHO Current path: %cd%
SET /p UserInputPath=Input relative path to directory:
ROBOCOPY /MIR empty_dir %cd%\%UserInputPath% > NUL
PAUSE

Here you are using empty directory named empty_dir in robocopy command that needs to be in same directory with batch file for this to work. After batch file finishes its job both selected directory and empty_dir directory will be empty so that you can remove them.

I made a simple batch file that creates empty folder and after robocopy command is executed removes both empty folder and selected folder so that only thing you need to do is enter path to selected folder that you want to delete. It is fast and practical if you don't want to install stuff like rimraf. You can download it here https://github.com/5imun/WinCleaner

I'm going to go against the grain here and state that the principle of separating content from layout (which would justify the answers that suggest using CSS) does not always apply to image height and width.

Each image has an innate, original height and width that can be derived from the image data. In the framework of content vs layout, I would say that this derived height and width information is content, not layout, and should therefore be rendered as HTML as element attributes.

This is much like the alt text, which can also be said to be derived from the image. This also supports the idea that an arbitrary user agent (e.g. a speech browser) should have that information in order to relate it to the user. At the least, the aspect ratio could prove useful ("image has a width of 15 and a height of 200"). Such user agents wouldn't necessarily process any CSS.

The spec says that the width and height attributes can also be used to override the height and width conveyed in the actual image file. I am not suggesting they be used for this. To override height and width, I believe CSS (inline, embedded or external) is the best approach.

So depending on what you want to do, you would specify one and/or the other. I think ideally, the original height and width would always be specified as HTML element attributes, while styling information should optionally be conveyed in CSS.

"DataBaseName" is the name of our Data Base

Check Opacity, You can set this css property to the div, the <p> or using <span> you want to make transparent

And by the way, the font tag is deprecated, use css to style the text

div {

Here's a simple solution with lambdas:

root = Tk()
root.attributes("-fullscreen", True)
root.bind("<F11>", lambda event: root.attributes("-fullscreen",
                                    not root.attributes("-fullscreen")))
root.bind("<Escape>", lambda event: root.attributes("-fullscreen", False))
root.mainloop()

This will make the screen exit fullscreen when escape is pressed, and toggle fullscreen when F11 is pressed.

If you have the code to log_out(), rewrite it. Most likely, you can do:

static FILE *logfp = ...;

void log_out(const char *fmt, ...)
{
    va_list args;

    va_start(args, fmt);
    vfprintf(logfp, fmt, args);
    va_end(args);
}

If there is extra logging information needed, that can be printed before or after the message shown. This saves memory allocation and dubious buffer sizes and so on and so forth. You probably need to initialize logfp to zero (null pointer) and check whether it is null and open the log file as appropriate - but the code in the existing log_out() should be dealing with that anyway.

The advantage to this solution is that you can simply call it as if it was a variant of printf(); indeed, it is a minor variant on printf().

If you don't have the code to log_out(), consider whether you can replace it with a variant such as the one outlined above. Whether you can use the same name will depend on your application framework and the ultimate source of the current log_out() function. If it is in the same object file as another indispensable function, you would have to use a new name. If you cannot work out how to replicate it exactly, you will have to use some variant like those given in other answers that allocates an appropriate amount of memory.

void log_out_wrapper(const char *fmt, ...)
{
    va_list args;
    size_t  len;
    char   *space;

    va_start(args, fmt);
    len = vsnprintf(0, 0, fmt, args);
    va_end(args);
    if ((space = malloc(len + 1)) != 0)
    {
         va_start(args, fmt);
         vsnprintf(space, len+1, fmt, args);
         va_end(args);
         log_out(space);
         free(space);
    }
    /* else - what to do if memory allocation fails? */
}

Obviously, you now call the log_out_wrapper() instead of log_out() - but the memory allocation and so on is done once. I reserve the right to be over-allocating space by one unnecessary byte - I've not double-checked whether the length returned by vsnprintf() includes the terminating null or not.

As for me, i need the view diraction:

in -> swipe from right

out -> swipe to left

Here works for me code:

slide_in_right.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromXDelta="50%p" android:toXDelta="0"
            android:duration="@android:integer/config_mediumAnimTime"/>
    <alpha android:fromAlpha="0.0" android:toAlpha="1.0"
            android:duration="@android:integer/config_mediumAnimTime" />
</set>

slide_out_left.xml

 <set xmlns:android="http://schemas.android.com/apk/res/android">
        <translate android:fromXDelta="0" android:toXDelta="-50%p"
                android:duration="@android:integer/config_mediumAnimTime"/>
        <alpha android:fromAlpha="1.0" android:toAlpha="0.0"
                android:duration="@android:integer/config_mediumAnimTime" />
    </set>

transaction code:

inline fun FragmentActivity.setContentFragment(
        containerViewId: Int,
        backStack: Boolean = false,
        isAnimate: Boolean = false,
        f: () -> Fragment

): Fragment? {
    val manager = supportFragmentManager
    return f().apply {
        manager.beginTransaction().let {
            if (isAnimate)
                it.setCustomAnimations(R.anim.slide_in_right, R.anim.slide_out_left)

            if (backStack) {
                it.replace(containerViewId, this, "Fr").addToBackStack("Fr").commit()
            } else {
                it.replace(containerViewId, this, "Fr").commit()
            }
        }
    }
}

You're on the right track with using document.getElementById() as you have done for your first two text boxes. Use something like document.getElementById("textbox3") to retrieve the element. Then you can just set its value property: document.getElementById("textbox3").value = answer;

For the "Your answer is: --", I'd recommend wrapping the "--" in a <span/> (e.g. <span id="answerDisplay">--</span>). Then use document.getElementById("answerDisplay").textContent = answer; to display it.

For me, in Python 3, it's working simply in this way:

keep = keep.union((0,1,2,3,4,5,6,7,8,9,10))

I don't know if it may be correct...

My bad, in trying to simplify it, I went too far, actually stuffs is a record of all kinds of info, I just want the id in it.

stuffs = [[123, first, last], [456, first, last]]

I want my_sting to be

my_sting = '123, 456'

My original code should have looked like this:

{% set my_string = '' %}
{% for stuff in stuffs %}
{% set my_string = my_string + stuff.id + ', '%}
{% endfor%}

Thinking about it, stuffs is probably a dictionary, but you get the gist.

Yes I found the join filter, and was going to approach it like this:

 {% set my_string = [] %}
 {% for stuff in stuffs %}
 {% do my_string.append(stuff.id) %}
 {% endfor%}
 {%  my_string|join(', ') %}

But the append doesn't work without importing the extensions to do it, and reading that documentation gave me a headache. It doesn't explicitly say where to import it from or even where you would put the import statement, so I figured finding a way to concat would be the lesser of the two evils.

It is very subjective. I write this:

while(true) {} //in C++

Because its intent is very much clear and it is also readable: you look at it and you know infinite loop is intended.

One might say for(;;) is also clear. But I would argue that because of its convoluted syntax, this option requires extra knowledge to reach the conclusion that it is an infinite loop, hence it is relatively less clear. I would even say there are more number of programmers who don't know what for(;;) does (even if they know usual for loop), but almost all programmers who knows while loop would immediately figure out what while(true) does.

To me, writing for(;;) to mean infinite loop, is like writing while() to mean infinite loop — while the former works, the latter does NOT. In the former case, empty condition turns out to be true implicitly, but in the latter case, it is an error! I personally didn't like it.

Now while(1) is also there in the competition. I would ask: why while(1)? Why not while(2), while(3) or while(0.1)? Well, whatever you write, you actually mean while(true) — if so, then why not write it instead?

In C (if I ever write), I would probably write this:

while(1) {} //in C

While while(2), while(3) and while(0.1) would equally make sense. But just to be conformant with other C programmers, I would write while(1), because lots of C programmers write this and I find no reason to deviate from the norm.

When you use command=self.root.destroy you pass the method to Tkinter.Button without the parentheses because you want Tkinter.Button to store the method for future calling, not to call it immediately when the button is created.

But when you define the quit method, you need to call self.root.destroy() in the body of the method because by then the method has been called.

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

I think rgba is the quickest and easiest!

If you don’t need to pass arguments through then here’s a compact UAC prompting script that’s a single line long. This does a similar thing as the elevation script in the top voted answer but doesn’t pass arguments through since there’s no foolproof way to do that that handles every possible combination of poison characters.

net sess>nul 2>&1||(echo(CreateObject("Shell.Application"^).ShellExecute"%~0",,,"RunAs",1:CreateObject("Scripting.FileSystemObject"^).DeleteFile(wsh.ScriptFullName^)>"%temp%\%~nx0.vbs"&start wscript.exe "%temp%\%~nx0.vbs"&exit)

Place this just below the @echo off line in your batch script.

Explanation

The net sess>nul 2>&1 part is what checks for elevation. net sess is just shorthand for net session which is a command that returns an error code when the script doesn’t have elevated rights. I got this idea from this SO answer. Most of the answers here use net file instead though which works the same.

The error level is then checked with the || operator. If the check succeeds then it creates and executes a WScript which re-runs the original batch file but with elevated rights before deleting itself.

The WScript file is the best approach being fast and reliable, although it uses a temporary file. Here are some other variations and their dis/advantages.

PowerShell

net sess>nul 2>&1||(powershell saps '%0'-Verb RunAs&exit)

Pros:

• Very short.
• No temporary files.

Cons:

• Slow. PowerShell can be very slow to start up.
• Spews red text when the user declines the UAC prompt. The PowerShell command could be wrapped in a try..catch to prevent this though.

Mshta WSH script

net sess>nul 2>&1||(start mshta.exe vbscript:code(close(Execute("CreateObject(""Shell.Application"").ShellExecute""%~0"",,,""RunAs"",1"^)^)^)&exit)

Pros:

• Fast.
• No temporary files.

Cons:

• Not reliable. Some Windows 10 machines will block the script from running as Windows Defender intercepts it as a potential trojan.

I am not sure what you need the app/installation ID for, but you can review the existing possibilities in a great article from Android developers:

• http://android-developers.blogspot.com/2011/03/identifying-app-installations.html

To sum up:

• UUID.randomUUID() for creating id on the first time an app runs after installation and simple retrieval afterwards
• TelephonyManager.getDeviceId() for actual device identifier
• Settings.Secure.ANDROID_ID on relatively modern devices

Keep an in-memory list like this

user_id   revoke_tokens_issued_before
-------------------------------------

If your tokens expire in one week then clean or ignore the records older than that. Also keep only the most recent record of each user. The size of the list will depend on how long you keep your tokens and how often users revoke their tokens. Use db only when the table changes. Load the table in memory when your application starts.

The C++ semantics of const are very different from Java final. If the designers had used const it would have been unnecessarily confusing.

The fact that const is a reserved word suggests that the designers had ideas for implementing const, but they have since decided against it; see this closed bug. The stated reasons include that adding support for C++ style const would cause compatibility problems.

I had to drop the extra quoting using msysGit on windows 7, not sure why.

You can use MSSQL Server Auditing feature. From version SQL Server 2012 you will find this feature in all editions:

http://technet.microsoft.com/en-us/library/cc280386.aspx

If you don't want to keep strings out of it, this works as well (Put it into a function):

DECLARE @Day int, @Month int, @Year int
SELECT @Day = 1, @Month = 2, @Year = 2008

SELECT DateAdd(dd, @Day-1, DateAdd(mm, @Month -1, DateAdd(yy, @Year - 2000, '20000101')))

In ZSH this is dead easy (note this uses more bash compatible syntax than necessary where possible for ease of understanding):

# I always include an edge case to make sure each element
# is not being word split.
start=(one two three 'four 4' five)
work=(${(@)start})

idx=2
val=${work[idx]}

# How to remove a single element easily.
# Also works for associative arrays (at least in zsh)
work[$idx]=()

echo "Array size went down by one: "
[[ $#work -eq $(($#start - 1)) ]] && echo "OK"

echo "Array item "$val" is now gone: "
[[ -z ${work[(r)$val]} ]] && echo OK

echo "Array contents are as expected: "
wanted=("${start[@]:0:1}" "${start[@]:2}")
[[ "${(j.:.)wanted[@]}" == "${(j.:.)work[@]}" ]] && echo "OK"

echo "-- array contents: start --"
print -l -r -- "-- $#start elements" ${(@)start}
echo "-- array contents: work --"
print -l -r -- "-- $#work elements" "${work[@]}"

Results:

Array size went down by one:
OK
Array item two is now gone:
OK
Array contents are as expected:
OK
-- array contents: start --
-- 5 elements
one
two
three
four 4
five
-- array contents: work --
-- 4 elements

    <label > Upload Photo : </label> 
    <input type="file" id="file" name='file' onChange=" return submitForm();">
    <input type="hidden" id="filecount" value='0'>

Here is Ajax Code:

function submitForm() {

    var fcnt = $('#filecount').val();
    var fname = $('#filename').val();
    var imgclean = $('#file');
    if(fcnt<=5)
    {
    data = new FormData();
    data.append('file', $('#file')[0].files[0]);

    var imgname  =  $('input[type=file]').val();
     var size  =  $('#file')[0].files[0].size;

    var ext =  imgname.substr( (imgname.lastIndexOf('.') +1) );
    if(ext=='jpg' || ext=='jpeg' || ext=='png' || ext=='gif' || ext=='PNG' || ext=='JPG' || ext=='JPEG')

      contentType: false   // tell jQuery not to set contentType
    }).done(function(data) {
       if(data!='FILE_SIZE_ERROR' || data!='FILE_TYPE_ERROR' )
       {
        fcnt = parseInt(fcnt)+1;
        $('#filecount').val(fcnt);
        var img = '<div class="dialog" id ="img_'+fcnt+'" ><img src="<?php echo base_url() ?>/local_cdn/'+data+'"><a href="#" id="rmv_'+fcnt+'" onclick="return removeit('+fcnt+')" class="close-classic"></a></div><input type="hidden" id="name_'+fcnt+'" value="'+data+'">';
        $('#prv').append(img);

        }else
        {
          fname = data;
        }
         $('#filename').val(fname);
          imgclean.replaceWith( imgclean = imgclean.clone( true ) );
       }
       else
       {
         imgclean.replaceWith( imgclean = imgclean.clone( true ) );
         alert('SORRY SIZE AND TYPE ISSUE');
       }

    });
    return false;
  }//end size
  else

  }
  }//end filecount
  else
  {    imgclean.replaceWith( imgclean = imgclean.clone( true ) );
     alert('You Can not Upload more than 6 Photos');
  }
}

Here is PHP code :

$filetype = array('jpeg','jpg','png','gif','PNG','JPEG','JPG');
   foreach ($_FILES as $key )
    {

          $name =time().$key['name'];

          $path='local_cdn/'.$name;
          $file_ext =  pathinfo($name, PATHINFO_EXTENSION);
          if(in_array(strtolower($file_ext), $filetype))
          {
            if($key['name']<1000000)
            {

             @move_uploaded_file($key['tmp_name'],$path);
             echo $name;

            }
           else
           {
               echo "FILE_SIZE_ERROR";
           }
        }
        else
        {
            echo "FILE_TYPE_ERROR";
        }// Its simple code.Its not with proper validation.

Here upload and preview part done.Now if you want to delete and remove image from page and folder both then code is here for deletion. Ajax Part:

function removeit (arg) {
       var id  = arg;
       // GET FILE VALUE
       var fname = $('#filename').val();
       var fcnt = $('#filecount').val();
        // GET FILE VALUE

       $('#img_'+id).remove();
       $('#rmv_'+id).remove();
       $('#img_'+id).css('display','none');

        var dname  =  $('#name_'+id).val();
        fcnt = parseInt(fcnt)-1;
        $('#filecount').val(fcnt);
        var fname = fname.replace(dname, "");
        var fname = fname.replace(",,", "");
        $('#filename').val(fname);
        $.ajax({
          url: 'delete.php',
          type: 'POST',
          data:{'name':dname},
          success:function(a){
            console.log(a);
            }
        });
    } 

Here is PHP part(delete.php):

$path='local_cdn/'.$_POST['name'];

   if(@unlink($path))
   {
     echo "Success";
   }
   else
   {
     echo "Failed";
   }

jQuery now supports scrollTop as an animation variable.

$("#id").animate({"scrollTop": $("#id").scrollTop() + 100});

You no longer need to setTimeout/setInterval to scroll smoothly.

The same error occurred when I had another variable named mythread. That variable overwrote this and that's why I got error

This also works:

Model:

public class ViewModel
{         
    public HttpPostedFileBase File{ get; set; }
}

View:

@using (Html.BeginForm("Action", "Controller", FormMethod.Post, new 
                                       { enctype = "multipart/form-data" }))
{
    @Html.TextBoxFor(m => m.File, new { type = "file" })       
}

Controller action:

[HttpPost]
public ActionResult Action(ViewModel model)
{
    if (ModelState.IsValid)
    {
        var postedFile = Request.Files["File"];

       // now you can get and validate the file type:
        var isFileSupported= IsFileSupported(postedFile);

    }
}

public bool IsFileSupported(HttpPostedFileBase file)
            {
                var isSupported = false;

                switch (file.ContentType)
                {

                    case ("image/gif"):
                        isSupported = true;
                        break;

                    case ("image/jpeg"):
                        isSupported = true;
                        break;

                    case ("image/png"):
                        isSupported = true;
                        break;


                    case ("audio/mp3"):  
                        isSupported = true;
                        break;

                }

                return isSupported;
            }

First you need to download JQuery library from http://jquery.com/ then load the jquery library the following way within your html head tags

then you can test whether the jquery is working by coding your jquery code after the jquery loading script

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>

<!--LINK JQUERY-->
<script type="text/javascript" src="jquery-3.3.1.js"></script>
<!--PERSONAL SCRIPT JavaScript-->
<script type="text/javascript">
   $(function(){
      alert("My First Jquery Test");
   });
</script>

</head>
<body><!-- Your web--></body>
</html>

If you want to use your jquery scripts file seperately you must define the external .js file this way after the jquery library loading.

<script type="text/javascript" src="jquery-3.3.1.js"></script>
<script src="js/YourExternalJQueryScripts.js"></script>

Test in real time

I realize this is answered, but there is another option when you're dealing with objects.

If you have an object that might be:

{
   name: {
      first: "John",
      last: "Doe"
   }
}

You can use:

obj.get(property_name, value_if_null)

Like:

obj.get("name", {}).get("first", "Name is missing") 

By adding {} as the default value, if "name" is missing, an empty object is returned and passed through to the next get. This is similar to null-safe-navigation in C#, which would be like obj?.name?.first.

According to PHPMailer Manual, full answer would be :

$mail->AddEmbeddedImage(filename, cid, name);
//Example
$mail->AddEmbeddedImage('my-photo.jpg', 'my-photo', 'my-photo.jpg '); 

Use Case :

$mail->AddEmbeddedImage("rocks.png", "my-attach", "rocks.png");
$mail->Body = 'Embedded Image: <img alt="PHPMailer" src="cid:my-attach"> Here is an image!';

If you want to display an image with a remote URL :

$mail->addStringAttachment(file_get_contents("url"), "filename");

I realize this is an old thread, but for those taking @JasonMArcher's accepted answer above as fact, I'm surprised it has not been corrected many of us have known for years it is actually the PIPELINE adding the delay and NOTHING to do with whether it is Out-Null or not. In fact, if you run the tests below you will quickly see that the same "faster" casting to [void] and $void= that for years we all used thinking it was faster, are actually JUST AS SLOW and in fact VERY SLOW when you add ANY pipelining whatsoever. In other words, as soon as you pipe to anything, the whole rule of not using out-null goes into the trash.

Proof, the last 3 tests in the list below. The horrible Out-null was 32339.3792 milliseconds, but wait - how much faster was casting to [void]? 34121.9251 ms?!? WTF? These are REAL #s on my system, casting to VOID was actually SLOWER. How about =$null? 34217.685ms.....still friggin SLOWER! So, as the last three simple tests show, the Out-Null is actually FASTER in many cases when the pipeline is already in use.

So, why is this? Simple. It is and always was 100% a hallucination that piping to Out-Null was slower. It is however that PIPING TO ANYTHING is slower, and didn't we kind of already know that through basic logic? We just may not have know HOW MUCH slower, but these tests sure tell a story about the cost of using the pipeline if you can avoid it. And, we were not really 100% wrong because there is a very SMALL number of true scenarios where out-null is evil. When? When adding Out-Null is adding the ONLY pipeline activity. In other words....the reason a simple command like $(1..1000) | Out-Null as shown above showed true.

If you simply add an additional pipe to Out-String to every test above, the #s change radically (or just paste the ones below) and as you can see for yourself, the Out-Null actually becomes FASTER in many cases:

playORM can do it for you using S-SQL(Scalable SQL) which just adds partitioning such that you can do joins within partitions.

Simplest answer is the following.....

All members in C# always take the LEAST accessible modifier possible by default.

That is why all top level classes in an assembly are "internal" by default, which means they are public to the assembly they are in, but private or excluded from access to outside assemblies. The only other option for a top level class is public which is more accessible. For nested types its all private except for a few rare exceptions like members of enums and interfaces which can only be public. Some examples. In the case of top level classes and interfaces, the defaults are:

class Animal same as internal class Animal

interface Animal same as public interface Animal

In the case of nested classes and interfaces (inside types), the defaults are:

class Animal same as private class Animal

interface Animal same as private interface Animal

If you just assume the default is always the most private, then you do not need to use an accessors until you need to change the default. Easy.

There is a scala way (if you have a enough memory on working machine):

val arr = df.select("column").rdd.collect
println(arr(100))

If dataframe schema is unknown, and you know actual type of "column" field (for example double), than you can get arr as following:

val arr = df.select($"column".cast("Double")).as[Double].rdd.collect

thought I would update on this.

Found out that adding to the VB Module behind the spreadsheet does not actually register as a Macro.

So here is the solution:

1. Press ALT + F11
2. Click Insert > Module
3. Paste the following into the window:

Code

Function LastSavedTimeStamp() As Date
  LastSavedTimeStamp = ActiveWorkbook.BuiltinDocumentProperties("Last Save Time")
End Function

4. Save the module, close the editor and return to the worksheet.
5. Click in the Cell where the date is to be displayed and enter the following formula:

Code

=LastSavedTimeStamp()

I had the same issue when I was trying to connect to my IIS .NET Webservice from the Android emulator.

note: code to be used inside a command line, and you must have powershell preinstalled on os.

If you place anything in src/main/resources directory, then by default it will end up in your final *.jar. If you are referencing it from some other project and it cannot be found on a classpath, then you did one of those two mistakes:

1. *.jar is not correctly loaded (maybe typo in the path?)
2. you are not addressing the resource correctly, for instance: /src/main/resources/conf/settings.properties is seen on classpath as classpath:conf/settings.properties

Use the 'And' keyword for a logical and. Like this:

If Not ((filename = testFileName) And (fileName <> "")) Then

If you're on a remote server you can configure your web.config file like so:

<configuration>
<system.webServer>
    <httpErrors errorMode="Detailed" />
    <asp scriptErrorSentToBrowser="true"/>
</system.webServer>
<system.web>
    <customErrors mode="Off"/>
    <compilation debug="true"/>
</system.web>
