Programs & Examples On #System testing

In order to avoid this kind of ClassCastException, if you have:

class A
class B extends A

You can define a constructor in B that takes an object of A. This way we can do the "cast" e.g.:

public B(A a) {
    super(a.arg1, a.arg2); //arg1 and arg2 must be, at least, protected in class A
    // If B class has more attributes, then you would initilize them here
}

I had exact same error, I was not giving base package. Giving correct base package,ressolved it.

package com.ymc.backend.ymcbe;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan(basePackages="com.ymc.backend")
public class YmcbeApplication {

    public static void main(String[] args) {
        SpringApplication.run(YmcbeApplication.class, args);
    }

}

Note: not including .controller @ComponentScan(basePackages="com.ymc.backend.controller") because i have many other component classes which my project does not scan if i just give .controller

Here is my controller sample:

package com.ymc.backend.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
@CrossOrigin
@RequestMapping(value = "/user")
public class UserController {

    @PostMapping("/sendOTP")
    public String sendOTP() {
        return "OTP sent";
    };


}

I was looking for the same information. Finally found the answer from the link on the answer above by @Straseus

http://arguments.callee.info/2010/04/20/running-apache-and-node-js-together/

Here is the final solution to run apache website on port 80, node js service on port 8080 and use .htaccess RewriteRule

In the DocumentRoot of the apache website, add the following:

Options +FollowSymLinks -MultiViews

<IfModule mod_rewrite.c>

RewriteEngine on

# Simple URL redirect:
RewriteRule ^test.html$ http://arguments.callee.info:8000/test/ [P]

# More complicated (the user sees only "benchmark.html" in their address bar)
RewriteRule ^benchmark.html$ http://arguments.callee.info:8000/node?action=benchmark [P]

# Redirect a whole subdirectory:
RewriteRule ^node/(.*) http://arguments.callee.info:8000/$1 [P]

For the directory level redirect, the link above suggested (.+) rule, which requires one or more character after the 'node/'. I had to convert it to (.*) which is zero or more for my stuff to work.

Thanks a lot for the link @Straseus

I was looking for the same feature but I don't use MySQL. I wanted to copy ALL the fields except of course the primary key (id). This was a one shot query, not to be used in any script or code.

I found my way around with PL/SQL but I'm sure any other SQL IDE would do. I did a basic

SELECT * 
FROM mytable 
WHERE id=42;

Then export it to a SQL file where I could find the

INSERT INTO table (col1, col2, col3, ... , col42) 
VALUES (1, 2, 3, ..., 42);

I just edited it and used it :

INSERT INTO table (col1, col2, col3, ... , col42) 
VALUES (mysequence.nextval, 2, 3, ..., 42);

If your moving to angular 8 or 9 this will do the trick

ng update @angular/cli

Read the manual, it covers it very well: http://php.net/manual/en/function.mysql-query.php

Usually you do something like this:

while ($row = mysql_fetch_assoc($result)) {
  echo $row['firstname'];
  echo $row['lastname'];
  echo $row['address'];
  echo $row['age'];
}

background-attachment: fixed;

As a general rule, you can use Database_Default collation so you don't need to figure out which one to use. However, I strongly suggest reading Simons Liew's excellent article Understanding the COLLATE DATABASE_DEFAULT clause in SQL Server

SELECT *
  FROM [FAEB].[dbo].[ExportaComisiones] AS f
  JOIN [zCredifiel].[dbo].[optPerson] AS p
  ON (p.vTreasuryId = f.RFC) COLLATE Database_Default 

I use numpy.fromiter to invert a 8-greyscale bitmap, yet no signs of side-effects

import Image
import numpy as np

im = Image.load('foo.jpg')
im = im.convert('L')

arr = np.fromiter(iter(im.getdata()), np.uint8)
arr.resize(im.height, im.width)

arr ^= 0xFF  # invert
inverted_im = Image.fromarray(arr, mode='L')
inverted_im.show()

For an instance

Character.Gorgon gor = new Character.Gorgon();

Then do

gor instanceof Monster

For a Class instance do

Class<?> clazz = Character.Gorgon.class;
Monster.class.isAssignableFrom(clazz);

if you don't want to start nginx as root.

first creat log file :

sudo touch /var/log/nginx/error.log

and then fix permissions:

sudo chown -R www-data:www-data /var/log/nginx

sudo find /var/log/nginx -type f -exec chmod 666 {} \;

sudo find /var/log/nginx -type d -exec chmod 755 {} \;

Use typeof arrayName[index] === 'undefined'

i.e.

if(typeof arrayName[index] === 'undefined') {
    // does not exist
}
else {
    // does exist
}

SQLite has a printf function which does exactly that:

SELECT printf('%s-%.2d-%.4d', col1, col2, col3) FROM mytable

The only real use case for GROUP BY without aggregation is when you GROUP BY more columns than are selected, in which case the selected columns might be repeated. Otherwise you might as well use a DISTINCT.

It's worth noting that other RDBMS's do not require that all non-aggregated columns be included in the GROUP BY. For example in PostgreSQL if the primary key columns of a table are included in the GROUP BY then other columns of that table need not be as they are guaranteed to be distinct for every distinct primary key column. I've wished in the past that Oracle did the same as it would have made for more compact SQL in many cases.

This is a message for me in the future:

Just use: (unsigned)!((int)0)

It creates the largest possible number in any machine by assigning all bits to 1s (ones) and then casts it to unsigned

Even better

#define INF (unsigned)!((int)0)

And then just use INF in your code

Checking out more than one repo at a time in a single workspace is possible with Jenkins + Git Plugin (maybe only in more recent versions?).

In section "Source-Code-Management", do not select "Git", but "Multiple SCMs" and add several git repositories.

Be sure that in all but one you add as an "Additional behavior" the action "Check out to a sub-directory" and specify an individual subdirectory.

The methods provide different layers of abstraction.

• $.ajax() gives you full control over the Ajax request. You should use it if the other methods don't fullfil your needs.

• $.get() executes an Ajax GET request. The returned data (which can be any data) will be passed to your callback handler.

• $(selector).load() will execute an Ajax GET request and will set the content of the selected returned data (which should be either text or HTML).

It depends on the situation which method you should use. If you want to do simple stuff, there is no need to bother with $.ajax().

E.g. you won't use $.load(), if the returned data will be JSON which needs to be processed further. Here you would either use $.ajax() or $.get().

Well, I was having the same trouble while uploading and I resolved it by doing the same thing which it says to do: Earlier I was trying to push through terminal to my repository in linux by https like

git push https://github.com/SiddharthChoudhary/ClientServerCloudComputing.git

But was not getting any result and hence I went down deeper and tried:

git push --set-upstream https://github.com/SiddharthChoudhary/ClientServerCloudComputing.git master

And it worked. Thus then you will get prompted with username and password. I also generated a token and instead of Password I pasted the token and thus, being done successfully.

1. To generate a token go to your Github account and in Developer Settings and then create another token.
2. After getting that, copy that token and paste in the password prompt when it's been asked.

This should help. Its CSS3 :first-child where you should say that the first tr of the table you would like to style. http://reference.sitepoint.com/css/pseudoclass-firstchild

Codes starting with 4 (4xx) are meant for client errors. Maybe 400 (Bad Request) could be suitable to this case? Definition in http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html says:

"The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications. "

As this post already contains a lot of different solutions i thought i post another one.

function onlyUnique(value, index, self) {
    return self.indexOf(value) === index;
}

function overload() {
   var functions = arguments;
   var nroffunctionsarguments = [arguments.length];
    for (var i = 0; i < arguments.length; i++) {
        nroffunctionsarguments[i] = arguments[i].length;
    }
    var unique = nroffunctionsarguments.filter(onlyUnique);
    if (unique.length === arguments.length) {
        return function () {
            var indexoffunction = nroffunctionsarguments.indexOf(arguments.length);
            return functions[indexoffunction].apply(this, arguments);
        }
    }
    else throw new TypeError("There are multiple functions with the same number of parameters");

}

this can be used as shown below:

var createVector = overload(
        function (length) {
            return { x: length / 1.414, y: length / 1.414 };
        },
        function (a, b) {
            return { x: a, y: b };
        },
        function (a, b,c) {
            return { x: a, y: b, z:c};
        }
    );
console.log(createVector(3, 4));
console.log(createVector(3, 4,5));
console.log(createVector(7.07));

This solution is not perfect but i only want to demonstrate how it could be done.

I've experienced "internal errors" in the .NET runtime that turned out to be caused by bugs in my code; don't think that just because it was an "internal error" in the .NET runtime that there isn't a bug in your code as the root cause. Always always always blame your own code before you blame someone else's.

Hopefully you have logging and exception/stack trace information to point you where to start looking, or that you can repeat the state of the system before the crash.

I suspect that your GIT_SSH environment variable is set to %ProgramFiles(x86)%\putty\plink.exe. For some reason, PLink does not use the .ssh/known_hosts file in your user directory to store the remote hosts keys.

If this is actually your case, and it might be so on purpose if you want to use pageant, you need to use PLink to connect to the host first.

"$GIT_SSH" user@hostname

You should get a similar message

The server's host key is not cached in the registry. You
have no guarantee that the server is the computer you

If you trust this host, enter "y" to add the key to
PuTTY's cache and carry on connecting.
If you want to carry on connecting just once, without
adding the key to the cache, enter "n".
If you do not trust this host, press Return to abandon the
connection.

Once you have answered y to the question and successfully connected to the remote host, you should be all set. Go ahead and try your push again.

Following Code Currency Mask for EditText ($ 123,125.155)

            isEdiging = false;
        }
    });

I saw the answers here and although helpful, they weren't exactly what I wanted since I had to alter a lot of my code.

What worked out for me, was doing something like this:

function isSession(selector) {
    //line added for the var that will have the result
    var result = false;
    $.ajax({
        type: "POST",
        url: '/order.html',
        data: ({ issession : 1, selector: selector }),
        dataType: "html",
        //line added to get ajax response in sync
        async: false,
        success: function(data) {
            //line added to save ajax response in var result
            result = data;
        },
        error: function() {
            alert('Error occured');
        }
    });
    //line added to return ajax response
    return result;
}

I use this pattern fairly frequently - I've found that it gives me a pretty huge amount of flexibility when I need it. In use it's rather similar to Java-style classes.

var Foo = function()
{

    var privateStaticMethod = function() {};
    var privateStaticVariable = "foo";

    var constructor = function Foo(foo, bar)
    {
        var privateMethod = function() {};
        this.publicMethod = function() {};
    };

    constructor.publicStaticMethod = function() {};

    return constructor;
}();

This uses an anonymous function that is called upon creation, returning a new constructor function. Because the anonymous function is called only once, you can create private static variables in it (they're inside the closure, visible to the other members of the class). The constructor function is basically a standard Javascript object - you define private attributes inside of it, and public attributes are attached to the this variable.

Basically, this approach combines the Crockfordian approach with standard Javascript objects to create a more powerful class.

You can use it just like you would any other Javascript object:

Foo.publicStaticMethod(); //calling a static method
var test = new Foo();     //instantiation
test.publicMethod();      //calling a method

With :before and :after you specify which content should be inserted before (or after) the content inside of that element. input elements have no content.

E.g. if you write <input type="text">Test</input> (which is wrong) the browser will correct this and put the text after the input element.

The only thing you could do is to wrap every input element in a span or div and apply the CSS on these.

See the examples in the specification:

For example, the following document fragment and style sheet:

<h2> Header </h2>               h2 { display: run-in; }
<p> Text </p>                   p:before { display: block; content: 'Some'; }

...would render in exactly the same way as the following document fragment and style sheet:

<h2> Header </h2>            h2 { display: run-in; }
<p><span>Some</span> Text </p>  span { display: block }

This is the same reason why it does not work for <br>, <img>, etc. (<textarea> seems to be special).

An org.json.JSONArray is not iterable.
Here's how I process elements in a net.sf.json.JSONArray:

    JSONArray lineItems = jsonObject.getJSONArray("lineItems");
    for (Object o : lineItems) {
        JSONObject jsonLineItem = (JSONObject) o;
        String key = jsonLineItem.getString("key");
        String value = jsonLineItem.getString("value");
        ...
    }

Works great... :)

If you use windows authentication, and you don't know a password to login as a user via username and password, you can do this: on the login-screen on SSMS click options at the bottom right, then go to the connection properties tab. Then you can type in manually the name of another database you have access to, over where it says , which will let you connect. Then follow the other advice for changing your default database

https://gyazo.com/c3d04c600311c08cb685bb668b569a67

Go to the start menu. Open up cmd (command prompt) and type in the following.

wmic process list brief | find /i "tomcat"

This would tell you if the tomcat is running or not.

You can also get the last command from history and subtract its EndExecutionTime from its StartExecutionTime.

.\do_something.ps1  
$command = Get-History -Count 1  
$command.EndExecutionTime - $command.StartExecutionTime

From what I saw in Express 4.0 this works for me. This is example of authentication required middleware.

function apiDemandLoggedIn(req, res, next) {

    // if user is authenticated in the session, carry on
    console.log('isAuth', req.isAuthenticated(), req.user);
    if (req.isAuthenticated())
        return next();

    // If not return 401 response which means unauthroized.
    var err = new Error();
    err.status = 401;
    next(err);
}

The nearest equivalents would be icode and bcode as used by scalac, view Miguel Garcia's site on the Scalac optimiser for more information, here: http://magarciaepfl.github.io/scala/

You might also consider Java bytecode itself to be your intermediate representation, given that bytecode is the ultimate output of scalac.

Or perhaps the true intermediate is something that the JIT produces before it finally outputs native instructions?

Ultimately though... There's no single place that you can point at an claim "there's the intermediate!". Scalac works in phases that successively change the abstract syntax tree, every single phase produces a new intermediate. The whole thing is like an onion, and it's very hard to try and pick out one layer as somehow being more significant than any other.

For chat applications or any other application that is in constant conversation with the server, WebSockets are the best option. However, you can only use WebSockets with a server that supports them, so that may limit your ability to use them if you cannot install the required libraries. In which case, you would need to use Long Polling to obtain similar functionality.

It's possible in ggplot and you can use scale_date for this task

 library(ggplot2)  
 Lines <- "Date            Visits
    11/1/2010   696537
    11/2/2010   718748
    11/3/2010   799355
    11/4/2010   805800
    11/5/2010   701262
    11/6/2010   531579
    11/7/2010   690068
    11/8/2010   756947
    11/9/2010   718757
    11/10/2010  701768
    11/11/2010  820113
    11/12/2010  645259"
    dm <- read.table(textConnection(Lines), header = TRUE)
    dm <- mutate(dm, Date = as.Date(dm$Date, "%m/%d/%Y"))
    ggplot(data = dm, aes(Date, Visits)) + 
    geom_line() + 
    scale_x_date(format = "%b %d", major =  "1 day")

Any expression that always returns true should be OK for while loop.

Example:

1==1 //Just an example for the text stated before 
true

If the object that needs access to the container is a bean in the container, just implement the BeanFactoryAware or ApplicationContextAware interfaces.

If an object outside the container needs access to the container, I've used a standard GoF singleton pattern for the spring container. That way, you only have one singleton in your application, the rest are all singleton beans in the container.

With CSS3 we can easily adjust an image. But remember this does not change the image. It only displays the adjusted image.

See the following code for more details.

To make an image gray:

img {
 -webkit-filter: grayscale(100%);
}

To give a sepia look:

img {
 -webkit-filter: sepia(100%);
}

To adjust brightness:

img {
 -webkit-filter: brightness(50%);
}

To adjust contrast:

img {
 -webkit-filter: contrast(200%);
}

To Blur an image:

img {
 -webkit-filter: blur(10px);
}

You should also do it for different browser. That is include all css statements

  filter: grayscale(100%);
 -webkit-filter: grayscale(100%);
 -moz-filter: grayscale(100%);

To use multiple

 filter: blur(5px) grayscale(1);

In general you can concatenate a whole sequence of arrays along any axis:

numpy.concatenate( LIST, axis=0 )

but you do have to worry about the shape and dimensionality of each array in the list (for a 2-dimensional 3x5 output, you need to ensure that they are all 2-dimensional n-by-5 arrays already). If you want to concatenate 1-dimensional arrays as the rows of a 2-dimensional output, you need to expand their dimensionality.

As Jorge's answer points out, there is also the function stack, introduced in numpy 1.10:

numpy.stack( LIST, axis=0 )

This takes the complementary approach: it creates a new view of each input array and adds an extra dimension (in this case, on the left, so each n-element 1D array becomes a 1-by-n 2D array) before concatenating. It will only work if all the input arrays have the same shape—even along the axis of concatenation.

vstack (or equivalently row_stack) is often an easier-to-use solution because it will take a sequence of 1- and/or 2-dimensional arrays and expand the dimensionality automatically where necessary and only where necessary, before concatenating the whole list together. Where a new dimension is required, it is added on the left. Again, you can concatenate a whole list at once without needing to iterate:

numpy.vstack( LIST )

This flexible behavior is also exhibited by the syntactic shortcut numpy.r_[ array1, ...., arrayN ] (note the square brackets). This is good for concatenating a few explicitly-named arrays but is no good for your situation because this syntax will not accept a sequence of arrays, like your LIST.

There is also an analogous function column_stack and shortcut c_[...], for horizontal (column-wise) stacking, as well as an almost-analogous function hstack—although for some reason the latter is less flexible (it is stricter about input arrays' dimensionality, and tries to concatenate 1-D arrays end-to-end instead of treating them as columns).

Finally, in the specific case of vertical stacking of 1-D arrays, the following also works:

numpy.array( LIST )

...because arrays can be constructed out of a sequence of other arrays, adding a new dimension to the beginning.

If all the previous answers didn't give any solution, you should check your user privileges.

If you could login as root to mysql then you should add this:

CREATE USER 'root'@'192.168.1.100' IDENTIFIED BY  '***';
GRANT ALL PRIVILEGES ON * . * TO  'root'@'192.168.1.100' IDENTIFIED BY  '***' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;

Then try to connect again using mysql -ubeer -pbeer -h192.168.1.100. It should work.

Try this:

void drawInitialNim(int num1, int num2, int num3){
    int board[3][50] = {0}; // This is a local variable. It is not possible to use it after returning from this function. 

    int i, j, k;

    for(i=0; i<num1; i++)
        board[0][i] = 'O';
    for(i=0; i<num2; i++)
        board[1][i] = 'O';
    for(i=0; i<num3; i++)
        board[2][i] = 'O';

    for (j=0; j<3;j++) {
        for (k=0; k<50; k++) {
            if(board[j][k] != 0)
                printf("%c", board[j][k]);
        }
        printf("\n");
    }
}

There is the way of current thread getting:

Thread t = Thread.currentThread();

After you have got Thread class object (t) you are able to get information you need using Thread class methods.

Thread ID gettting:

long tId = t.getId(); // e.g. 14291

Thread name gettting:

String tName = t.getName(); // e.g. "pool-29-thread-7"

There is fundamental difference between query parameters and path parameters. It goes like this: www.your_domain?queryparam1=1&queryparam2=2 - query parameters. www.your_domain/path_param1/entity/path_param2 - path parameters.

What I found surprising is that in Spring MVC world a lot of people confuse one for the other. While query parameters are more like criteria for a search, path params will most likely uniquely identify a resource. Having said that, it doesn't mean that you can't have multiple path parameters in your URI, because the resource structure can be nested. For example, let's say you need a specific car resource of a specific person:

www.my_site/customer/15/car/2 - looking for a second car of a 15th customer.

What would be a usecase to put all path parameters into a map? Path parameters don't have a "key" when you look at a URI itself, those keys inside the map would be taken from your @Mapping annotation, for example:

@GetMapping("/booking/{param1}/{param2}")

From HTTP/REST perspective path parameters can't be projected onto a map really. It's all about Spring's flexibility and their desire to accommodate any developers whim, in my opinion.

I would never use a map for path parameters, but it can be quite useful for query parameters.

The lubridate package is amazing for this kind of thing:

A JavaScript accordion does the trick.

This fiddle by W3Schools makes a simple task even more simple using nothing but javascript, which i partially reproduce below.

<head>
<style>
button.accordion {
    background-color: #eee;
    color: #444;
    font-size: 15px;
    cursor: pointer;
}

button.accordion.active, button.accordion:hover {
    background-color: #ddd; 
}

div.panel {
    padding: 0 18px;
    display: none;
    background-color: white;
}

div.panel.show {
    display: block;
}
</style>
</head><body>
<script>
var acc = document.getElementsByClassName("accordion");
var i;

for (i = 0; i < acc.length; i++) {
    acc[i].onclick = function(){
    this.classList.toggle("active");
    this.nextElementSibling.classList.toggle("show");
  }
}
</script>
...
<button class="accordion">Section 1</button>
<div class="panel">
  <p>Lorem ipsum dolor sit amet</p>
</div>
...
<button class="accordion">Table</button>
<div class="panel">
  <p><table name="detail_table">...</table></p>
</div>
...
<button class="accordion"><table name="button_table">...</table></button>
<div class="panel">
  <p>Lorem ipsum dolor sit amet</p>
  <table name="detail_table">...</table>
  <img src=...></img>
</div>
...
</body></html>

if using php, don't forget to convert " to '. You can also use tables of data inside the button and it will still work.

  }
}

@-webkit-keyframes fadeIn {
  from {
    opacity: 0;
  }

  to {
    opacity: 1;
  }
}

This worked for me:

String.prototype.replaceAll = function(search, replacement) {
    var target = this;
    return target.replace(new RegExp(search, 'g'), replacement);
};

function replaceAll(str, map){
    for(key in map){
        str = str.replaceAll(key, map[key]);
    }
    return str;
}

//testing...
var str = "bat, ball, cat";
var map = {
    'bat' : 'foo',
    'ball' : 'boo',
    'cat' : 'bar'
};
var new = replaceAll(str, map);
//result: "foo, boo, bar"

Well, you have [[ and ]] to go to the start and end of file. This works in vi.

You cannot initialize an array like that. In addition to what others have suggested, you can do :

data[0] = 10;
data[1] = 20;
...
data[9] = 91;

I ran a similar test as @marcio but with the following loop instead:

String c = a;
for (long i = 0; i < 100000L; i++) {
    c = c.concat(b); // make sure javac cannot skip the loop
    // using c += b for the alternative
}

Just for good measure, I threw in StringBuilder.append() as well. Each test was run 10 times, with 100k reps for each run. Here are the results:

• StringBuilder wins hands down. The clock time result was 0 for most the runs, and the longest took 16ms.
• a += b takes about 40000ms (40s) for each run.
• concat only requires 10000ms (10s) per run.

I haven't decompiled the class to see the internals or run it through profiler yet, but I suspect a += b spends much of the time creating new objects of StringBuilder and then converting them back to String.

Here is some code. It uses 2 classes (Card.java and Deck.java) to accomplish this issue, and to top it off it auto sorts it for you when you create the deck object. :)

import java.util.*;

public class deck2 {
    ArrayList<Card> cards = new ArrayList<Card>();

    String[] values = {"A","2","3","4","5","6","7","8","9","10","J","Q","K"};
    String[] suit = {"Club", "Spade", "Diamond", "Heart"};

    static boolean firstThread = true;
    public deck2(){
        for (int i = 0; i<suit.length; i++) {
            for(int j=0; j<values.length; j++){
                this.cards.add(new Card(suit[i],values[j]));
            }
        }
        //shuffle the deck when its created
        Collections.shuffle(this.cards);

    }

    public ArrayList<Card> getDeck(){
        return cards;
    }

    public static void main(String[] args){
        deck2 deck = new deck2();

        //print out the deck.
        System.out.println(deck.getDeck());
    }

}


//separate class

public class Card {


    private String suit;
    private String value;


    public Card(String suit, String value){
        this.suit = suit;
        this.value = value;
    }
    public Card(){}
    public String getSuit(){
        return suit;
    }
    public void setSuit(String suit){
        this.suit = suit;
    }
    public String getValue(){
        return value;
    }
    public void setValue(String value){
        this.value = value;
    }

    public String toString(){
        return "\n"+value + " of "+ suit;
    }
}

You can also try using a C#/Perl/Java script get the utilization data using WMI Commands, and below is the steps for it.

We need to execute 2 WMI Select Queries and apply CPU% utilization formula

1. To retrieve the total number of logical process

select NumberOfLogicalProcessors from Win32_ComputerSystem

2. To retrieve the values of PercentProcessorTime, TimeStamp_Sys100NS ( CPU utilization formula has be applied get the actual utilization percentage)and WorkingSetPrivate ( RAM ) minimum of 2 times with a sleep interval of 1 second

select * from Win32_PerfRawData_PerfProc_Process where IDProcess=1234

3. Apply CPU% utilization formula

CPU%= ((p2-p1)/(t2-t1)*100)/NumberOfLogicalProcessors

p2 indicated PercentProcessorTime retrieved for the second time, and p1 indicateds the PercentProcessorTime retrieved for the first time, t2 and t1 is for TimeStamp_Sys100NS.

A sample Perl code for this can be found in the link http://www.craftedforeveryone.com/cpu-and-ram-utilization-of-an-application-using-perl-via-wmi/

This logic applies for all programming language which supports WMI queries

This is a function we are using in our application and it is working fine.

delete cookie: No argument method

function clearListCookies()
{   
    var cookies = document.cookie.split(";");
    for (var i = 0; i < cookies.length; i++)
    {   
        var spcook =  cookies[i].split("=");
        deleteCookie(spcook[0]);
    }
    function deleteCookie(cookiename)
    {
        var d = new Date();
        d.setDate(d.getDate() - 1);
        var expires = ";expires="+d;
        var name=cookiename;
        //alert(name);
        var value="";
        document.cookie = name + "=" + value + expires + "; path=/acc/html";                    
    }
    window.location = ""; // TO REFRESH THE PAGE
}

Edit: This will delete the cookie by setting it to yesterday's date.

Here's the solution I used in Kotlin

private fun startTimer()
{
    Log.d(TAG, ":startTimer: timeString = '$timeString'")

    object : CountDownTimer(TASK_SWITCH_TIMER, 250)
    {
        override fun onTick(millisUntilFinished: Long)
        {
            val secondsUntilFinished : Long = 
            Math.ceil(millisUntilFinished.toDouble()/1000).toLong()
            val timeString = "${TimeUnit.SECONDS.toMinutes(secondsUntilFinished)}:" +
                    "%02d".format(TimeUnit.SECONDS.toSeconds(secondsUntilFinished))
            Log.d(TAG, ":startTimer::CountDownTimer:millisUntilFinished = $ttlseconds")
            Log.d(TAG, ":startTimer::CountDownTimer:millisUntilFinished = $millisUntilFinished")
        }

        @SuppressLint("SetTextI18n")
        override fun onFinish()
        {
            timerTxtVw.text = "0:00"
            gameStartEndVisibility(true)
        }
    }.start()
}

[NSTimer scheduledTimerWithTimeInterval:.06 target:self selector:@selector(goToSecondButton:) userInfo:nil repeats:NO];

Is the best one to use. Using sleep(15); will cause the user unable to perform any other actions. With the following function, you would replace goToSecondButton with the appropriate selector or command, which can also be from the frameworks.

If they're contiguous, you can just do

x[2:6] = []

If you want to remove noncontiguous indexes, it's a little trickier.

x = [v for i,v in enumerate(x) if i not in frozenset((2,3,4,5))] 

Try this one.

ALTER TABLE tb_TableName
ALTER COLUMN Record_Status VARCHAR(20) NOT NULL

ALTER TABLE tb_TableName
ADD CONSTRAINT DEF_Name DEFAULT '' FOR Record_Status

ConfigurationSettings.AppSettings is deprecated, see here:

http://msdn.microsoft.com/en-us/library/system.configuration.configurationsettings.appsettings.aspx

That said, it should still work.

Just a suggestion, but have you confirmed that your application configuration is the one your executable is using?

Try attaching a debugger and checking the following value:

AppDomain.CurrentDomain.SetupInformation.ConfigurationFile

And then opening the configuration file and verifying the section is there as you expected.

I've found another easy way to deal with this problem, you just need the attribute " connectToSortable:" to draggable like as below code:

$("#a1,#a2").draggable({
        connectToSortable: "#b,#a",
        revert: 'invalid',
    });

PS: More detail and example
How to move Draggable objects between source area and target area with jQuery

If you have it, try removing this from your vimrc: set mouse=a

It messes with the paste functionality.

There are a few functions like:

NSStringFromCGPoint  
NSStringFromCGSize  
NSStringFromCGRect  
NSStringFromCGAffineTransform  
NSStringFromUIEdgeInsets

An example:

NSLog(@"rect1: %@", NSStringFromCGRect(rect1));

Don`t forget to use DataGrid.Columns, all columns must be inside that collection. In my project I format date a little bit differently:

<tk:DataGrid>
    <tk:DataGrid.Columns>
        <tk:DataGridTextColumn Binding="{Binding StartDate, StringFormat=\{0:dd.MM.yy HH:mm:ss\}}" />
    </tk:DataGrid.Columns>
</tk:DataGrid>

With AutoGenerateColumns you won`t be able to contol formatting as DataGird will add its own columns.

You need to download mysql-connector-java-5.1.46.tar.gz, not the latest version. The Driver class that Pentaho uses is not included in mysql-connector-java-8.xx.yy versions.

Setting this will cause the refresh token to be sent every time:

$client->setApprovalPrompt('force');

an example is given below (php):

$client = new Google_Client();
$client->setClientId($client_id);
$client->setClientSecret($client_secret);
$client->setRedirectUri($redirect_uri);
$client->addScope("email");
$client->addScope("profile"); 
$client->setAccessType('offline');
$client->setApprovalPrompt('force');

It's a little trickier to do what you're trying to do than I'd prefer, but that's because you don't really directly bind a DataGrid to a DataTable.

When you bind DataGrid.ItemsSource to a DataTable, you're really binding it to the default DataView, not to the table itself. This is why, for instance, you don't have to do anything to make a DataGrid sort rows when you click on a column header - that functionality's baked into DataView, and DataGrid knows how to access it (through the IBindingList interface).

The DataView implements IEnumerable<DataRowView> (more or less), and the DataGrid fills its items by iterating over this. This means that when you've bound DataGrid.ItemsSource to a DataTable, its SelectedItem property will be a DataRowView, not a DataRow.

If you know all this, it's pretty straightforward to build a wrapper class that lets you expose properties that you can bind to. There are three key properties:

• Table, the DataTable,
• Row, a two-way bindable property of type DataRowView, and
• SearchText, a string property that, when it's set, will find the first matching DataRowView in the table's default view, set the Row property, and raise PropertyChanged.

It looks like this:

public class DataTableWrapper : INotifyPropertyChanged
{
    private DataRowView _Row;

    private string _SearchText;

    public DataTableWrapper()
    {
        // using a parameterless constructor lets you create it directly in XAML
        DataTable t = new DataTable();
        t.Columns.Add("id", typeof (int));
        t.Columns.Add("text", typeof (string));

        // let's acquire some sample data
        t.Rows.Add(new object[] { 1, "Tower"});
        t.Rows.Add(new object[] { 2, "Luxor" });
        t.Rows.Add(new object[] { 3, "American" });
        t.Rows.Add(new object[] { 4, "Festival" });
        t.Rows.Add(new object[] { 5, "Worldwide" });
        t.Rows.Add(new object[] { 6, "Continental" });
        t.Rows.Add(new object[] { 7, "Imperial" });

        Table = t;

    }

    // you should have this defined as a code snippet if you work with WPF
    private void OnPropertyChanged(string propertyName)
    {
        PropertyChangedEventHandler h = PropertyChanged;
        if (h != null)
        {
            h(this, new PropertyChangedEventArgs(propertyName));
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    // SelectedItem gets bound to this two-way
    public DataRowView Row
    {
        get { return _Row; }
        set
        {
            if (_Row != value)
            {
                _Row = value;
                OnPropertyChanged("Row");
            }
        }
    }

    // the search TextBox is bound two-way to this
    public string SearchText
    {
        get { return _SearchText; }
        set
        {
            if (_SearchText != value)
            {
                _SearchText = value;
                Row = Table.DefaultView.OfType<DataRowView>()
                    .Where(x => x.Row.Field<string>("text").Contains(_SearchText))
                    .FirstOrDefault();
            }
        }
    }

    public DataTable Table { get; private set; }
}

And here's XAML that uses it:

<Window x:Class="DataGridSelectionDemo.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        xmlns:dg="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit"
        xmlns:DataGridSelectionDemo="clr-namespace:DataGridSelectionDemo" 
        Title="DataGrid selection demo" 
        Height="350" 
        Width="525">
    <Window.DataContext>
        <DataGridSelectionDemo:DataTableWrapper />
    </Window.DataContext>
    <DockPanel>
        <Grid DockPanel.Dock="Top">
        <Grid.ColumnDefinitions>
                <ColumnDefinition Width="Auto" />
                <ColumnDefinition Width="*" />
            </Grid.ColumnDefinitions>
            <Label>Text</Label>
            <TextBox Grid.Column="1" 
                     Text="{Binding SearchText, Mode=TwoWay}" />
        </Grid>
        <dg:DataGrid DockPanel.Dock="Top"
                     ItemsSource="{Binding Table}"
                     SelectedItem="{Binding Row, Mode=TwoWay}" />
    </DockPanel>
</Window>

Let's create a decently complicated stacktrace, in order to demonstrate that we get the full stacktrace:

def raise_error():
    raise RuntimeError('something bad happened!')

def do_something_that_might_error():
    raise_error()

Logging the full stacktrace

A best practice is to have a logger set up for your module. It will know the name of the module and be able to change levels (among other attributes, such as handlers)

import logging
logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger(__name__)

And we can use this logger to get the error:

try:
    do_something_that_might_error()
except Exception as error:
    logger.exception(error)

Which logs:

ERROR:__main__:something bad happened!
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "<stdin>", line 2, in do_something_that_might_error
  File "<stdin>", line 2, in raise_error
RuntimeError: something bad happened!

And so we get the same output as when we have an error:

>>> do_something_that_might_error()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in do_something_that_might_error
  File "<stdin>", line 2, in raise_error
RuntimeError: something bad happened!

Getting just the string

If you really just want the string, use the traceback.format_exc function instead, demonstrating logging the string here:

import traceback
try:
    do_something_that_might_error()
except Exception as error:
    just_the_string = traceback.format_exc()
    logger.debug(just_the_string)

Which logs:

DEBUG:__main__:Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "<stdin>", line 2, in do_something_that_might_error
  File "<stdin>", line 2, in raise_error
RuntimeError: something bad happened!

You could try merge

var finalObj = $.merge(json1, json2);

Simplest answer is:

Step 1: Fire up Terminal.app

Step 2: Type nano .bash_profile – This command will open the .bash_profile document (or create it if it doesn’t already exist) in the easiest to use text editor in Terminal – Nano.

Step 3: Now you can make a simple change to the file. Paste these lines of code to change your Terminal prompt.

export PS1="___________________ | \w @ \h (\u) \n| => "

export PS2="| => "

Step 4: Now save your changes by typing ctrl +o Hit return to save. Then exit Nano by typing ctrl+x

Step 5: Now we need to *activate your changes. Type source .bash_profile and watch your prompt change.

That's it! Enjoy!

I find the answer from @Austin Phillips is spot on. One small improvement I'd do is to add -o (to ignore the pid of the script itself) and match for the script with basename (ie same code can be put into any script):

if pidof -x "`basename $0`" -o $$ >/dev/null; then
    echo "Process already running"
fi

Just want to add one more way. Found it elsewhere, and is quite simple. Say I want to pass yes for all the prompts at command line for a command "execute_command", Then I would simply pipe yes to it.

yes | execute_command

This will use yes as the answer to all yes/no prompts.

    <?php
if (isset($_POST['birthdate'])) {
    $timestamp = strtotime($_POST['birthdate']); 
    $date=date('d',$timestamp);
    $month=date('m',$timestamp);
    $year=date('Y',$timestamp);
}
?>  

I had this error with MySQL as my database and the only solution was reinstall all components of MySQL, because before I installed just the server.

So try to download other versions of PostgreSQL and get all the components

This is my solution:

public static int hex2decimal(String s) {
    int val = 0;
    for (int i = 0; i < s.length(); i++) {
        char c = s.charAt(i);
        int num = (int) c;
        val = 256*val + num;
    }
    return val;
}

For example to convert 3E8 to 1000:

StringBuffer sb = new StringBuffer();
sb.append((char) 0x03);
sb.append((char) 0xE8);
int n = hex2decimal(sb.toString());
System.out.println(n); //will print 1000.

Below code will help you:

public class DeckListAdapter extends BaseAdapter{

      private LayoutInflater mInflater;
        ArrayList<String> teams=new ArrayList<String>();
        ArrayList<Integer> teamcolor=new ArrayList<Integer>();


        public DeckListAdapter(Context context) {
            // Cache the LayoutInflate to avoid asking for a new one each time.
            mInflater = LayoutInflater.from(context);

            teams.add("Upload");
            teams.add("Download");
            teams.add("Device Browser");
            teams.add("FTP Browser");
            teams.add("Options");

            teamcolor.add(Color.WHITE);
            teamcolor.add(Color.LTGRAY);
            teamcolor.add(Color.WHITE);
            teamcolor.add(Color.LTGRAY);
            teamcolor.add(Color.WHITE);


        }



        public int getCount() {
            return teams.size();
        }


        public Object getItem(int position) {
            return position;
        }


        public long getItemId(int position) {
            return position;
        }

       @Override
        public View getView(final int position, View convertView, ViewGroup parent) {
            final ViewHolder holder;


            if (convertView == null) {
                convertView = mInflater.inflate(R.layout.decklist, null);

                holder = new ViewHolder();
                holder.icon = (ImageView) convertView.findViewById(R.id.deckarrow);
                holder.text = (TextView) convertView.findViewById(R.id.textname);

             .......here you can use holder.text.setonclicklistner(new View.onclick.

                        for each textview


                System.out.println(holder.text.getText().toString());

                convertView.setTag(holder);
            } else {

                holder = (ViewHolder) convertView.getTag();
            }



             holder.text.setText(teams.get(position));

             if(position<teamcolor.size())
             holder.text.setBackgroundColor(teamcolor.get(position));

             holder.icon.setImageResource(R.drawable.arraocha);







            return convertView;
        }

        class ViewHolder {
            ImageView icon;
            TextView text;



        }
}

Hope this helps.

if div.title is a div then put this:

left: 0;
bottom: 0;

You could do this:

echo "<script>alert('Successfully Updated'); window.location = './edit.php';</script>";

I was experiencing a similar error message that I noticed in the Windows Event Viewer that read:

Login failed for user 'NT AUTHORITY\NETWORK SERVICE'. Reason: Failed to open the explicitly specified database. [CLIENT: local machine]

The solution that resolved my problem was:

1. Login to SqlExpress via SQL Server Management Studio
2. Go to the "Security" directory of the database
3. Right-click the Users directory
4. Select "New User..."
5. Add 'NT AUTHORITY\NETWORK SERVICE' as a new user

Here's a screenshot of the above:

This is a bit old but I ran into the requirement so here is the solution I came up with.

The Problem:

Our development team maintains many .NET web application products we are migrating to AngularJS/Bootstrap. VS2010 does not lend itself easily to custom build processes and my developers are routinely working on multiple releases of our products. Our VCS is Subversion (I know, I know. I'm trying to move to Git but my pesky marketing staff is so demanding) and a single VS solution will include several separate projects. I needed my staff to have a common method for initializing their development environment without having to install the same Node packages (gulp, bower, etc.) several times on the same machine.

TL;DR:

1. Need "npm install" to install the global Node/Bower development environment as well as all locally required packages for a .NET product.

2. Global packages should be installed only if not already installed.

3. Local links to global packages must be created automatically.

The Solution:

We already have a common development framework shared by all developers and all products so I created a NodeJS script to install the global packages when needed and create the local links. The script resides in "....\SharedFiles" relative to the product base folder:

Now if I want to update a global tool for our developers, I update the "packages" object and check in the new script. My developers check it out and either run it with "node npm-setup.js" or by "npm install" from any of the products under development to update the global environment. The whole thing takes 5 minutes.

In addition, to configure the environment for the a new developer, they must first only install NodeJS and GIT for Windows, reboot their computer, check out the "Shared Files" folder and any products under development, and start working.

The "package.json" for the .NET product calls this script prior to install:

{ 
"name"                    : "Books",
"description"             : "Node (npm) configuration for Books Database Web Application Tools",
"version"                 : "2.1.1",
"private"                 : true,
"scripts":
  {
  "preinstall"            : "node ../../SharedFiles/npm-setup.js links",
  "postinstall"           : "bower install"
  },
"dependencies": {}
}

Notes

• Note the script reference requires forward slashes even in a Windows environment.

• "npm ls" will give "npm ERR! extraneous:" messages for all packages locally linked because they are not listed in the "package.json" "dependencies".

Edit 1/29/16

The updated npm-setup.js script above has been modified as follows:

• Package "version" in var packages is now the "package" value passed to npm install on the command line. This was changed to allow for installing packages from somewhere other than the registered repository.

• If the package is already installed but is not the one requested, the existing package is removed and the correct one installed.

• For reasons unknown, npm will periodically throw an EBUSY error (-4082) when performing an install or link. This error is trapped and the command re-executed. The error rarely happens a second time and seems to always clear up.

I have a very simple answer. Just put this formula in cell A2:

=Max($A$1:A1)+1

and fill down.

This sets row number automatically, even if you remove some rows or sort rows.

If you use same color for whole program , you can define printf() function.

   #include<stdio.h>
   #define ah_red "\e[31m"
   #define printf(X) printf(ah_red "%s",X);
   #int main()
   {
        printf("Bangladesh");
        printf("\n");
        return 0;
   }

Comments about previous answers

The universal solution is using the HTML tag <sup>, as suggested in the main answer.
However, the idea behind Markdown is precisely to avoid the use of such tags:
The document should look nice as plain text, not only when rendered.

Another answer proposes using Unicode characters, which makes the document look nice as a plain text document but could reduce compatibility.

Finally, I would like to remember the simplest solution for some documents: the character ^.
Some Markdown implementation (e.g. MacDown in macOS) interprets the caret as an instruction for superscript.

Ex.
Sin^2 + Cos^2 = 1
Clearly, Stack Overflow does not interpret the caret as a superscript instruction. However, the text is comprehensible, and this is what really matters when using Markdown.

The only difference is that CHARACTER VARYING is more human friendly than VARCHAR

Official answer: http://blog.cocoapods.org/Master-Spec-Repo-Rate-Limiting-Post-Mortem/

As a result of this discussion https://github.com/CocoaPods/CocoaPods/issues/4989

Briefly: CocoaPods repository experiences a huge volume of fetches from GitHub and it was the problem. Changes have been available since version 1.0.0.beta.6.

Tips from this document:

If for whatever reason you cannot upgrade to version 1.0.0 just yet, you can perform the following steps to convert your clone of the Master spec-repo from a shallow to a full clone:

$ cd ~/.cocoapods/repos/master
$ git fetch --unshallow

My hack to first installation:

1. pod setup
2. Ctrl+C
After that I could find ~/.cocoapods/repos/ empty directory 
3. Download  https://github.com/CocoaPods/Specs/archive/master.zip
4. unpack it to ~/.cocoapods/repos/
5. Move to project folder
6. pod install --no-repo-update

Today it takes near 15 minutes

While not using datetime, this solves your problem (answers your question) of getting a string with the current time and date format you specify:

import time
timestr = time.strftime("%Y%m%d-%H%M%S")
print timestr

yields:

20120515-155045

so your filename could append or use this string.

if you have two divs, you can use this to align the divs next to each other in the same row:

#keyword {_x000D_
    float:left;_x000D_
    margin-left:250px;_x000D_
    position:absolute;_x000D_
}_x000D_
_x000D_
#bar {_x000D_
    text-align:center;_x000D_
}

<div id="keyword">_x000D_
Keywords:_x000D_
</div>_x000D_
<div id="bar">_x000D_
    <input type = textbox   name ="keywords" value="" onSubmit="search()" maxlength=40>_x000D_
    <input type = button   name="go" Value="Go ahead and find" onClick="search()">_x000D_
</div>

The best practice is to check if the array key exists using the built-in array_key_exists function.

On git version 2.8.1: following works for me.

To save modified and untracked files in stash without a name

git stash save -u

To save modified and untracked files in stash with a name

git stash save -u <name_of_stash>

You can use either pop or apply later as follows.

git stash pop

git stash apply stash@{0}

I think what you want is:

select {
  direction: rtl;
}

Here's another way to do it in VBA.

Function ConvertToArray(ByVal value As String)
    value = StrConv(value, vbUnicode)
    ConvertToArray = Split(Left(value, Len(value) - 1), vbNullChar)
End Function
Sub example()
    Dim originalString As String
    originalString = "hi there"
    Dim myArray() As String
    myArray = ConvertToArray(originalString)
End Sub

The nature of wanting to include the row where A == 5 and all rows upto but not including the row where A == 8 means we will end up using iloc (loc includes both ends of slice).

In order to get the index labels we use idxmax. This will return the first position of the maximum value. I run this on a boolean series where A == 5 (then when A == 8) which returns the index value of when A == 5 first happens (same thing for A == 8).

Then I use searchsorted to find the ordinal position of where the index label (that I found above) occurs. This is what I use in iloc.

i5, i8 = df.index.searchsorted([df.A.eq(5).idxmax(), df.A.eq(8).idxmax()])
df.iloc[i5:i8]

numpy

you can further enhance this by using the underlying numpy objects the analogous numpy functions. I wrapped it up into a handy function.

def find_between(df, col, v1, v2):
    vals = df[col].values
    mx1, mx2 = (vals == v1).argmax(), (vals == v2).argmax()
    idx = df.index.values
    i1, i2 = idx.searchsorted([mx1, mx2])
    return df.iloc[i1:i2]

find_between(df, 'A', 5, 8)

I do think that realizing Haskell's feature by examples is the best way to start above all.

http://en.wikipedia.org/wiki/Haskell_98_features

Here is tricky typeclasses including monads and arrows

http://www.haskell.org/haskellwiki/Typeclassopedia

for real world problems and bigger project, remember these tags: GHC(most used compiler), Hackage(libraryDB), Cabal(building system), darcs(another building system).

A integrated system can save your time: http://hackage.haskell.org/platform/

the package database for this system: http://hackage.haskell.org/

GHC compiler's wiki: http://www.haskell.org/haskellwiki/GHC

After Haskell_98_features and Typeclassopedia, I think you already can find and read the documention about them yourself

By the way, you may want to test some GHC's languages extension which may be a part of haskell standard in the future.

this is my best way for learning haskell. i hope it can help you.

You can only use Core Graphics (Quartz, 2D only) transforms directly applied to a UIView's transform property. To get the effects in coverflow, you'll have to use CATransform3D, which are applied in 3-D space, and so can give you the perspective view you want. You can only apply CATransform3Ds to layers, not views, so you're going to have to switch to layers for this.

Check out the "CovertFlow" sample that comes with Xcode. It's mac-only (ie not for iPhone), but a lot of the concepts transfer well.

Use LINQ .Cast<int>() to convert 2D array to IEnumerable<int>.

LINQPad example:

var arr = new int[,] { 
  { 1, 2, 3 }, 
  { 4, 5, 6 } 
};

IEnumerable<int> values = arr.Cast<int>();
Console.WriteLine(values);

Login to virtual machine use below command to check ip address. (anyone will work)

1. ifconfig
2. ip addr show

If you used NAT for your virtual machine settings(your machine ip will be 10.0.2.15), then you have to use port forwarding to connect to machine. IP address will be 127.0.0.1

If you used bridged networking/Host only networking, then you will have separate Ip address. Use that IP address to connect virtual machine

Try this:

<div id="wrapper">
    <div class="float left">left</div>
    <div class="float right">right</div>
</div>

#wrapper {
   width:500px; 
   height:300px; 
   position:relative;
}

.float {
   background-color:black; 
   height:300px; 
   margin:0; 
   padding:0; 
   color:white;
}

.left {
   background-color:blue; 
   position:fixed; 
   width:400px;
}

.right {
   float:right; 
   width:100px;
}

As the PHP.net manual suggests, take a read of this discussion.

One major difference is that echo can take multiple parameters to output. E.g.:

echo 'foo', 'bar';   // Concatenates the 2 strings
print('foo', 'bar'); // Fatal error

If you're looking to evaluate the outcome of an output statement (as below) use print. If not, use echo.

$res = print('test');
var_dump($res); //bool(true)

In my case, boolean values in my Python dict were the problem. JSON boolean values are in lowercase ("true", "false") whereas in Python they are in Uppercase ("True", "False"). Couldn't find this solution anywhere online but hope it helps.

If there's changes in your submodules, then use

git submodule foreach --recursive git reset --hard

If your changes are remote submodule changes, then use

git submodule update --init

If these changes have been committed, then use

git reset --hard
git submodule update --init

An instance variable would probably be the way to do what you want. You could make it static to persist the same value for the life of the program (or thread depending on your static memory model), or make it an ordinary instance var to control it over the life of an object instance. If that instance is a singleton, they'll behave the same way.

#if DEBUG
private /*static*/ bool s_bDoDebugOnlyCode = false;
#endif

void foo()
{   
  // ...
#if DEBUG
  if (s_bDoDebugOnlyCode)
  {
      // Code here gets executed only when compiled with the DEBUG constant, 
      // and when the person debugging manually sets the bool above to true.  
      // It then stays for the rest of the session until they set it to false.
  }
#endif
 // ...
}

Just to be complete, pragmas (preprocessor directives) are considered a bit of a kludge to use to control program flow. .NET has a built-in answer for half of this problem, using the "Conditional" attribute.

private /*static*/ bool doDebugOnlyCode = false; 
[Conditional("DEBUG")]
void foo()
{   
  // ...    
  if (doDebugOnlyCode)
  {
      // Code here gets executed only when compiled with the DEBUG constant, 
      // and when the person debugging manually sets the bool above to true.  
      // It then stays for the rest of the session until they set it to false.
  }    
  // ...
}

No pragmas, much cleaner. The downside is that Conditional can only be applied to methods, so you'll have to deal with a boolean variable that doesn't do anything in a release build. As the variable exists solely to be toggled from the VS execution host, and in a release build its value doesn't matter, it's pretty harmless.

If you know what column the text/pattern you're looking for (e.g. "yyy") is in, you can just check that specific column to see if it matches, and print it.

For example, given a file with the following contents, (called asdf.txt)

xxx yyy zzz

to only print the second column if it matches the pattern "yyy", you could do something like this:

awk '$2 ~ /yyy/ {print $2}' asdf.txt

Note that this will also match basically any line where the second column has a "yyy" in it, like these:

xxx yyyz zzz
xxx zyyyz

You could use OrderedDict (requires Python 2.7) or higher.

Also, note that OrderedDict({'a': 1, 'b':2, 'c':3}) won't work since the dict you create with {...} has already forgotten the order of the elements. Instead, you want to use OrderedDict([('a', 1), ('b', 2), ('c', 3)]).

As mentioned in the documentation, for versions lower than Python 2.7, you can use this recipe.

callback from adapter to activity can be done using registering listener in form of interface: Make an interface:

      public MyInterface{
         public void  yourmethod(//incase needs parameters );
         }

In Adapter Let's Say MyAdapter:

    public MyAdapter extends BaseAdapter{
       private MyInterface listener;

    MyAdapter(Context context){
        try {
            this. listener = (( MyInterface ) context);
              } catch (ClassCastException e) {
               throw new ClassCastException("Activity must implement MyInterface");
          }

//do this where u need to fire listener l

          try {
                listener . yourmethod ();
            } catch (ClassCastException exception) {
               // do something
            }

      In Activity Implement your method:


         MyActivity extends AppCompatActivity implements MyInterface{

                yourmethod(){
                //do whatever you want
                     }
                     }

StringBuilder sb = new StringBuilder();
sb.Append("Line 1");
sb.Append(System.Environment.NewLine); //Change line
sb.Append("\t"); //Add tabulation
sb.Append("Line 2");
using (StreamWriter sw = new StreamWriter("example.txt"))
{
    sw.Write(sb.ToString());
}

You can find detailed documentation on TAB (and other escape character here).

Are you looking for this?:

my $thisfile = $1 if $0 =~
/\\([^\\]*)$|\/([^\/]*)$/;

print "You are running $thisfile
now.\n";

The output will look like this:

It works on both Windows and Unix.

In order to include the number of row index "columns" in your total shape I would personally add together the number of columns df.columns.size with the attribute pd.Index.nlevels/pd.MultiIndex.nlevels:

Set up dummy data

import pandas as pd

flat_index = pd.Index([0, 1, 2])
multi_index = pd.MultiIndex.from_tuples([("a", 1), ("a", 2), ("b", 1), names=["letter", "id"])

columns = ["cat", "dog", "fish"]

data = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
flat_df = pd.DataFrame(data, index=flat_index, columns=columns)
multi_df = pd.DataFrame(data, index=multi_index, columns=columns)

# Show data
# -----------------
# 3 columns, 4 including the index
print(flat_df)
    cat  dog  fish
id                
0     1    2     3
1     4    5     6
2     7    8     9

# -----------------
# 3 columns, 5 including the index
print(multi_df)
           cat  dog  fish
letter id                
a      1     1    2     3
       2     4    5     6
b      1     7    8     9

def total_ncols(df, include_index=False):
    ncols = df.columns.size
    if include_index is True:
        ncols += df.index.nlevels
    return ncols

print("Ignore the index:")
print(total_ncols(flat_df), total_ncols(multi_df))

print("Include the index:")
print(total_ncols(flat_df, include_index=True), total_ncols(multi_df, include_index=True))

This prints:

Ignore the index:
3 3

Include the index:
4 5

If you want to only include the number of indices if the index is a pd.MultiIndex, then you can throw in an isinstance check in the defined function.

As an alternative, you could use df.reset_index().columns.size to achieve the same result, but this won't be as performant since we're temporarily inserting new columns into the index and making a new index before getting the number of columns.

Lets say you have 17 mod 6.

what total of 6 will get you the closest to 17, it will be 12 because if you go over 12 you will have 18 which is more that the question of 17 mod 6. You will then take 12 and minus from 17 which will give you your answer, in this case 5.

17 mod 6=5

For checking the empty string in shell

if [ "$str" == "" ];then
   echo NULL
fi

OR

if [ ! "$str" ];then
   echo NULL
fi

I think in this case concat is what you want:

In [12]:

pd.concat([df,df1], axis=0, ignore_index=True)
Out[12]:
   attr_1  attr_2  attr_3  id  quantity
0       0       1     NaN   1        20
1       1       1     NaN   2        23
2       1       1     NaN   3        19
3       0       0     NaN   4        19
4       1     NaN       0   5         8
5       0     NaN       1   6        13
6       1     NaN       1   7        20
7       1     NaN       1   8        25

by passing axis=0 here you are stacking the df's on top of each other which I believe is what you want then producing NaN value where they are absent from their respective dfs.

Add import pdb; pdb.set_trace() or breakpoint() (form python3.7) at the corresponding line in the Python code and execute it. The execution will stop with an interactive shell. In the shell you can execute Python code (i.e. print variables) or use commands such as:

• c continue execution
• n step to the next line within the same function
• s step to the next line in this function or a called function
• q quit the debugger/execution

The for loop runs immediately to completion while all your asynchronous operations are started. When they complete some time in the future and call their callbacks, the value of your loop index variable i will be at its last value for all the callbacks.

This is because the for loop does not wait for an asynchronous operation to complete before continuing on to the next iteration of the loop and because the async callbacks are called some time in the future. Thus, the loop completes its iterations and THEN the callbacks get called when those async operations finish. As such, the loop index is "done" and sitting at its final value for all the callbacks.

To work around this, you have to uniquely save the loop index separately for each callback. In Javascript, the way to do that is to capture it in a function closure. That can either be done be creating an inline function closure specifically for this purpose (first example shown below) or you can create an external function that you pass the index to and let it maintain the index uniquely for you (second example shown below).

As of 2016, if you have a fully up-to-spec ES6 implementation of Javascript, you can also use let to define the for loop variable and it will be uniquely defined for each iteration of the for loop (third implementation below). But, note this is a late implementation feature in ES6 implementations so you have to make sure your execution environment supports that option.

Use .forEach() to iterate since it creates its own function closure

someArray.forEach(function(item, i) {
    asynchronousProcess(function(item) {
        console.log(i);
    });
});

Create Your Own Function Closure Using an IIFE

var j = 10;
for (var i = 0; i < j; i++) {
    (function(cntr) {
        // here the value of i was passed into as the argument cntr
        // and will be captured in this function closure so each
        // iteration of the loop can have it's own value
        asynchronousProcess(function() {
            console.log(cntr);
        });
    })(i);
}

Create or Modify External Function and Pass it the Variable

If you can modify the asynchronousProcess() function, then you could just pass the value in there and have the asynchronousProcess() function the cntr back to the callback like this:

var j = 10;
for (var i = 0; i < j; i++) {
    asynchronousProcess(i, function(cntr) {
        console.log(cntr);
    });
}

Use ES6 let

If you have a Javascript execution environment that fully supports ES6, you can use let in your for loop like this:

const j = 10;
for (let i = 0; i < j; i++) {
    asynchronousProcess(function() {
        console.log(i);
    });
}

let declared in a for loop declaration like this will create a unique value of i for each invocation of the loop (which is what you want).

Serializing with promises and async/await

If your async function returns a promise, and you want to serialize your async operations to run one after another instead of in parallel and you're running in a modern environment that supports async and await, then you have more options.

async function someFunction() {
    const j = 10;
    for (let i = 0; i < j; i++) {
        // wait for the promise to resolve before advancing the for loop
        await asynchronousProcess();
        console.log(i);
    }
}

This will make sure that only one call to asynchronousProcess() is in flight at a time and the for loop won't even advance until each one is done. This is different than the previous schemes that all ran your asynchronous operations in parallel so it depends entirely upon which design you want. Note: await works with a promise so your function has to return a promise that is resolved/rejected when the asynchronous operation is complete. Also, note that in order to use await, the containing function must be declared async.

Run asynchronous operations in parallel and use Promise.all() to collect results in order

 function someFunction() {
     let promises = [];
     for (let i = 0; i < 10; i++) {
          promises.push(asynchonousProcessThatReturnsPromise());
     }
     return Promise.all(promises);
 }

 someFunction().then(results => {
     // array of results in order here
     console.log(results);
 }).catch(err => {
     console.log(err);
 });

You can't edit the image via CSS. The only solution I can think of is to edit the image and change its opacity, or make different images with all the opacities needed.

Well, if you have a number like 0.123456 that is the result of a division to give a percentage, multiply it by 100 and then either round it or use toFixed like in your example.

Math.round(0.123456 * 100) //12

Here is a jQuery plugin to do that:

jQuery.extend({
    percentage: function(a, b) {
        return Math.round((a / b) * 100);
    }
});

Usage:

alert($.percentage(6, 10));

It is important to highlight that the Property (MaximumErrorCount) that needs to be changed must be set as more than 0 (which is the default) in the Package level and not in the specific control that is showing the error (I tried this and it does not work!)

Be sure that in the Properties Window, the Pull down menu is set to "Package", then look for the property MaximumErrorCount to change it.

With Spring Boot its not necessary to have any config file like persistence.xml. You can configure with annotations Just configure your DB config for JPA in the

application.properties

spring.datasource.driverClassName=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@DB...
spring.datasource.username=username
spring.datasource.password=pass

spring.jpa.database-platform=org.hibernate.dialect....
spring.jpa.show-sql=true

Then you can use CrudRepository provided by Spring where you have standard CRUD transaction methods. There you can also implement your own SQL's like JPQL.

@Transactional
public interface ObjectRepository extends CrudRepository<Object, Long> {
...
}

And if you still need to use the Entity Manager you can create another class.

public class ObjectRepositoryImpl implements ObjectCustomMethods{

    @PersistenceContext
    private EntityManager em;

}

This should be in your pom.xml

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.5.RELEASE</version>

Combining the top-rated answer with the second-top-rated answer to get the filename without the full path:

$ x="/foo/fizzbuzz.bar.quux"
$ y=(`basename ${x%%.*}`)
$ echo $y
fizzbuzz

If you are using vscode and you are on Windows i would recommend you to click the option at the bottom-right of the window and set it to LF from CRLF. Because we should not turn off the configuration just for sake of removing errors on Windows

If you don't see LF / CLRF, then right click the status bar and select Editor End of Line.

d={1:'a',2:'b'}
sum=0
for i in range(0,len(d),1):
   sum=sum+1
i=i+1
print i

OUTPUT=2

This works:

var t = $('#taCommentSalesAdministration');
t.val('Hi');

Remember, the tricky part here is making sure you use the correct ID. And before you use the ID make sure you put # before it.

You can use PyPdf2s PdfMerger class.

File Concatenation

You can simply concatenate files by using the append method.

from PyPDF2 import PdfFileMerger

pdfs = ['file1.pdf', 'file2.pdf', 'file3.pdf', 'file4.pdf']

merger = PdfFileMerger()

for pdf in pdfs:
    merger.append(pdf)

merger.write("result.pdf")
merger.close()

You can pass file handles instead file paths if you want.

File Merging

If you want more fine grained control of merging there is a merge method of the PdfMerger, which allows you to specify an insertion point in the output file, meaning you can insert the pages anywhere in the file. The append method can be thought of as a merge where the insertion point is the end of the file.

e.g.

merger.merge(2, pdf)

Here we insert the whole pdf into the output but at page 2.

Page Ranges

If you wish to control which pages are appended from a particular file, you can use the pages keyword argument of append and merge, passing a tuple in the form (start, stop[, step]) (like the regular range function).

e.g.

merger.append(pdf, pages=(0, 3))    # first 3 pages
merger.append(pdf, pages=(0, 6, 2)) # pages 1,3, 5

If you specify an invalid range you will get an IndexError.

Note: also that to avoid files being left open, the PdfFileMergers close method should be called when the merged file has been written. This ensures all files are closed (input and output) in a timely manner. It's a shame that PdfFileMerger isn't implemented as a context manager, so we can use the with keyword, avoid the explicit close call and get some easy exception safety.

You might also want to look at the pdfcat script provided as part of pypdf2. You can potentially avoid the need to write code altogether.

The PyPdf2 github also includes some example code demonstrating merging.

You need to transform the object you are getting back into an array in the format that jQueryUI expects.

You can use $.map to transform the dealers object into that array.

$('#dealerName').autocomplete({
    source: function (request, response) {
        $.getJSON("/example/location/example.json?term=" + request.term, function (data) {
            response($.map(data.dealers, function (value, key) {
                return {
                    label: value,
                    value: key
                };
            }));
        });
    },
    minLength: 2,
    delay: 100
});

Note that when you select an item, the "key" will be placed in the text box. You can change this by tweaking the label and value properties that $.map's callback function return.

Alternatively, if you have access to the server-side code that is generating the JSON, you could change the way the data is returned. As long as the data:

• Is an array of objects that have a label property, a value property, or both, or
• Is a simple array of strings

In other words, if you can format the data like this:

[{ value: "1463", label: "dealer 5"}, { value: "269", label: "dealer 6" }]

or this:

["dealer 5", "dealer 6"]

Then your JavaScript becomes much simpler:

$('#dealerName').autocomplete({
    source: "/example/location/example.json"
});

There are many way to achieve, one from them I use always

 Request::url()

Another way to think of it is to calculate the unit vector for a given direction and then apply a 90 degree counterclockwise rotation to get the normal vector.

The matrix representation of the general 2D transformation looks like this:

x' = x cos(t) - y sin(t)
y' = x sin(t) + y cos(t)

where (x,y) are the components of the original vector and (x', y') are the transformed components.

If t = 90 degrees, then cos(90) = 0 and sin(90) = 1. Substituting and multiplying it out gives:

x' = -y
y' = +x

Same result as given earlier, but with a little more explanation as to where it comes from.

m - sets margin

p - sets padding

t - sets margin-top or padding-top

b - sets margin-bottom or padding-bottom

l - sets margin-left or padding-left

r - sets margin-right or padding-right

x - sets both padding-left and padding-right or margin-left and margin-right

y - sets both padding-top and padding-bottom or margin-top and margin-bottom

blank - sets a margin or padding on all 4 sides of the element

0 - sets margin or padding to 0

1 - sets margin or padding to .25rem (4px if font-size is 16px)

2 - sets margin or padding to .5rem (8px if font-size is 16px)

3 - sets margin or padding to 1rem (16px if font-size is 16px)

4 - sets margin or padding to 1.5rem (24px if font-size is 16px)

5 - sets margin or padding to 3rem (48px if font-size is 16px)

auto - sets margin to auto

Update 2020:

You can now use Modern ECMAScript syntax thanks to V8 Runtime.

You can use includes():

var grade = itemResponse.getResponse();
if(grade.includes("9th")){do something}

Most of these linker errors occur because of missing libraries.

I added the libstdc++.6.dylib in my Project->Targets->Build Phases-> Link Binary With Libraries.

That solved it for me on Xcode 6.3.2 for iOS 8.3

If u need to connect your application to a server you can do it through PHP/MySQL and JSON http://www.androidhive.info/2012/05/how-to-connect-android-with-php-mysql/ .Mysql Connection code should be in AsynTask class. Dont run it in Main Thread.

Since mindeavor stated that the object to be cloned is a 'literal-constructed' object, a solution might be to simply generate the object multiple times rather than cloning an instance of the object:

function createMyObject()
{
    var myObject =
    {
        ...
    };
    return myObject;
}

var myObjectInstance1 = createMyObject();
var myObjectInstance2 = createMyObject();

Another option is to use Promise.all to wait for an array of promises to resolve and then act on those.

Code below shows how to wait for all the promises to resolve and then deal with the results once they are all ready (as that seemed to be the objective of the question); Also for illustrative purposes, it shows output during execution (end finishes before middle).

function append_output(suffix, value) {
  $("#output_"+suffix).append(value)
}

function kickOff() {
  let start = new Promise((resolve, reject) => {
    append_output("now", "start")
    resolve("start")
  })
  let middle = new Promise((resolve, reject) => {
    setTimeout(() => {
      append_output("now", " middle")
      resolve(" middle")
    }, 1000)
  })
  let end = new Promise((resolve, reject) => {
    append_output("now", " end")
    resolve(" end")
  })

  Promise.all([start, middle, end]).then(results => {
    results.forEach(
      result => append_output("later", result))
  })
}

kickOff()

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Updated during execution: <div id="output_now"></div>
Updated after all have completed: <div id="output_later"></div>

The keyword final means that the value is constant(it cannot be changed). It is analogous to const in C.

And you can treat static as a global variable which has scope. It basically means if you change it for one object it will be changed for all just like a global variable(limited by scope).

Hope it helps.

When I got this problem I always try this solution and it works.

Instant Run disable 

Build -> Clean Project

File -> Invalidate Caches / Restart

But I found an exception this once. This solution doesn't work for me. Then I find out the problem is Emulator cash. I just do Wipe data and Cold boot now and the problem is solved.

   exec sp_execsql @Sql

The DB change only lasts for the time to complete @sql

If multiple clock are generated with different frequencies, then clock generation can be simplified if a procedure is called as concurrent procedure call. The time resolution issue, mentioned by Martin Thompson, may be mitigated a little by using different high and low time in the procedure. The test bench with procedure for clock generation is:

library ieee;
use ieee.std_logic_1164.all;

entity tb is
end entity;

architecture sim of tb is

  -- Procedure for clock generation
  procedure clk_gen(signal clk : out std_logic; constant FREQ : real) is
    constant PERIOD    : time := 1 sec / FREQ;        -- Full period
    constant HIGH_TIME : time := PERIOD / 2;          -- High time
    constant LOW_TIME  : time := PERIOD - HIGH_TIME;  -- Low time; always >= HIGH_TIME
  begin
    -- Check the arguments
    assert (HIGH_TIME /= 0 fs) report "clk_plain: High time is zero; time resolution to large for frequency" severity FAILURE;
    -- Generate a clock cycle
    loop
      clk <= '1';
      wait for HIGH_TIME;
      clk <= '0';
      wait for LOW_TIME;
    end loop;
  end procedure;

  -- Clock frequency and signal
  signal clk_166 : std_logic;
  signal clk_125 : std_logic;

begin

  -- Clock generation with concurrent procedure call
  clk_gen(clk_166, 166.667E6);  -- 166.667 MHz clock
  clk_gen(clk_125, 125.000E6);  -- 125.000 MHz clock

  -- Time resolution show
  assert FALSE report "Time resolution: " & time'image(time'succ(0 fs)) severity NOTE;

end architecture;

The time resolution is printed on the terminal for information, using the concurrent assert last in the test bench.

If the clk_gen procedure is placed in a separate package, then reuse from test bench to test bench becomes straight forward.

Waveform for clocks are shown in figure below.

An more advanced clock generator can also be created in the procedure, which can adjust the period over time to match the requested frequency despite the limitation by time resolution. This is shown here:

-- Advanced procedure for clock generation, with period adjust to match frequency over time, and run control by signal
procedure clk_gen(signal clk : out std_logic; constant FREQ : real; PHASE : time := 0 fs; signal run : std_logic) is
  constant HIGH_TIME   : time := 0.5 sec / FREQ;  -- High time as fixed value
  variable low_time_v  : time;                    -- Low time calculated per cycle; always >= HIGH_TIME
  variable cycles_v    : real := 0.0;             -- Number of cycles
  variable freq_time_v : time := 0 fs;            -- Time used for generation of cycles
begin
  -- Check the arguments
  assert (HIGH_TIME /= 0 fs) report "clk_gen: High time is zero; time resolution to large for frequency" severity FAILURE;
  -- Initial phase shift
  clk <= '0';
  wait for PHASE;
  -- Generate cycles
  loop
    -- Only high pulse if run is '1' or 'H'
    if (run = '1') or (run = 'H') then
      clk <= run;
    end if;
    wait for HIGH_TIME;
    -- Low part of cycle
    clk <= '0';
    low_time_v := 1 sec * ((cycles_v + 1.0) / FREQ) - freq_time_v - HIGH_TIME;  -- + 1.0 for cycle after current
    wait for low_time_v;
    -- Cycle counter and time passed update
    cycles_v := cycles_v + 1.0;
    freq_time_v := freq_time_v + HIGH_TIME + low_time_v;
  end loop;
end procedure;

Again reuse through a package will be nice.

Using the shell:

#!/bin/bash
prefix="something"
file="file"
while read -r line
do
 echo "${prefix}$line"
done <$file > newfile
mv newfile $file

By 'the wiz' I'm assuming you're talking about the 'SQL Server Import and Export Wizard'. (I'm also pretty new so I don't understand most questions, much less most answers, but I think I get this one). If so couldn't you take the spreadsheet, or a copy of it, delete the columns you don't want imported and then use the wizard?

I've always found the ability to do what I need with it and I'm only on SQL Server 2000 (not sure how other versions differ).

Edit: In fact I'm looking at it now and I seem to be able to choose which columns I want to map to which rows in an existing table. On the 'Select Source Tables and Views' screen I check the datasheet I'm using, select the 'Destination' then click the 'Edit...' button. From there you can choose the Excel column and the table column to map it to.

Try this:

public void LoadData()
        {
            SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=Stocks;Integrated Security=True;Pooling=False");
            SqlDataAdapter sda = new SqlDataAdapter("Select * From [Stocks].[dbo].[product]", con);
            DataTable dt = new DataTable();
            sda.Fill(dt);
            DataGridView1.Rows.Clear();

        foreach (DataRow item in dt.Rows)
        {
            int n = DataGridView1.Rows.Add();
            DataGridView1.Rows[n].Cells[0].Value = item["ProductCode"].ToString();
            DataGridView1.Rows[n].Cells[1].Value = item["Productname"].ToString();
            DataGridView1.Rows[n].Cells[2].Value = item["qty"].ToString();                
            if ((bool)item["productstatus"])
            {
                DataGridView1.Rows[n].Cells[3].Value = "Active";
            }
            else
            {
                DataGridView1.Rows[n].Cells[3].Value = "Deactive";
            }

I recently came across Python 3 interpreter at CompileOnline.

Solution using just POST - no $_SESSION

page1.php

<form action="page2.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>

page2.php

<?php
    // this page outputs the contents of the textarea if posted
    $textarea1 = ""; // set var to avoid errors
    if(isset($_POST['textarea1'])){
        $textarea1 = $_POST['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

Solution using $_SESSION and POST

page1.php

<?php

    session_start(); // needs to be before anything else on page to use $_SESSION
    $textarea1 = "";
    if(isset($_POST['textarea1'])){
        $_SESSION['textarea1'] = $_POST['textarea1'];
    }

?>


<form action="page1.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>
<br /><br />
<a href="page2.php">Go to page2</a>

page2.php

<?php
    session_start(); // needs to be before anything else on page to use $_SESSION
    // this page outputs the textarea1 from the session IF it exists
    $textarea1 = ""; // set var to avoid errors
    if(isset($_SESSION['textarea1'])){
        $textarea1 = $_SESSION['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

WARNING!!! - This contains no validation!!!

You could loop through the list and keep the tuple in a variable and then you can see both values from the same variable...

num=(0, 0)
for item in tuplelist:
  if item[1]>num[1]:
    num=item #num has the whole tuple with the highest y value and its x value

new ArrayList<>(Arrays.asList(array));

For people wanting to use the built-in .NET SmtpClient rather than the SendGrid client library (not sure if that was the OP's intent), I couldn't get it to work unless I used apikey as my username and the api key itself as the password as outlined here.

<mailSettings>
    <smtp>
        <network host="smtp.sendgrid.net" port="587" userName="apikey" password="<your key goes here>" />
    </smtp>
</mailSettings>

The answer is in here :

To declare a bounded type parameter, list the type parameter's name, followed by the extends keyword, followed by its upper bound […]. Note that, in this context, extends is used in a general sense to mean either extends (as in classes) or implements (as in interfaces).

So there you have it, it's a bit confusing, and Oracle knows it.

A column with default value:

CREATE TABLE <TableName>(
...
<ColumnName> <Type> DEFAULT <DefaultValue>
...
)

<DefaultValue> is a placeholder for a:

• value literal
• ( expression )

Examples:

Count INTEGER DEFAULT 0,
LastSeen TEXT DEFAULT (datetime('now'))

The best way to accomplish that is to use POST which is a method of Hypertext Transfer Protocol https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods

index.php

<html>
<body>

<form action="site2.php" method="post">
Name: <input type="text" name="name">
Email: <input type="text" name="email">
<input type="submit">
</form>

</body>
</html> 

site2.php

 <html>
 <body>

 Hello <?php echo $_POST["name"]; ?>!<br>
 Your mail is <?php echo $_POST["mail"]; ?>.

 </body>
 </html> 

output

Hello "name" !

Your email is "[email protected]" .

A simple example could be,

    import tensorflow as tf
    import numpy as np
    a=tf.random_normal([2,3],0.0,1.0,dtype=tf.float32)  #sampling from a std normal
    print(type(a))
    #<class 'tensorflow.python.framework.ops.Tensor'>
    tf.InteractiveSession()  # run an interactive session in Tf.

n now if we want this tensor a to be converted into a numpy array

    a_np=a.eval()
    print(type(a_np))
    #<class 'numpy.ndarray'>

As simple as that!

You need to publish the exposed ports by using the following options:

-P (upper case) or --publish-all that will tell Docker to use random ports from your host and map them to the exposed container's ports.

-p (lower case) or --publish=[] that will tell Docker to use ports you manually set and map them to the exposed container's ports.

The second option is preferred because you already know which ports are mapped. If you use the first option then you will need to call docker inspect demo and check which random ports are being used from your host at the Ports section.

Just run the following command:

docker run -it -p 8080:8080 demo

After that your url will work.

You are using getData() method as void.

You can not return values from void.

"abcd4yyyy" | grep 4 -c gives the count as 1

this problem is for CPU Architecture and you have some of the abi in the lib folder.

go to build.gradle for your app module and in android, block add this :

  splits {
            abi {
                enable true
                reset()
                include 'x86', 'armeabi-v7a'
                universalApk true
            }
        }

Interesting. The consensus from most of these answers seems to be that the redundant break statement is unnecessary clutter. On the other hand, I read the break statement in a switch as the 'closing' of a case. case blocks that don't end in a break tend to jump out at me as potential fall though bugs.

I know that that's not how it is when there's a return instead of a break, but that's how my eyes 'read' the case blocks in a switch, so I personally would prefer that each case be paired with a break. But many compilers do complain about the break after a return being superfluous/unreachable, and apparently I seem to be in the minority anyway.

So get rid of the break following a return.

NB: all of this is ignoring whether violating the single entry/exit rule is a good idea or not. As far as that goes, I have an opinion that unfortunately changes depending on the circumstances...

As said in the comments, the problem lies in your script. Actually, there are 2 problems:

• There is a matplotlib error, I guess that you're passing an argument as None somewhere. Maybe due to the defaultdict ?
• You call show() after each subplot. show() should be called once at the end of your script. The alternative is to use interactive mode, look for ion in matplotlib's documentation.

You can run the application file of project in simulator - not .ipa file.

You can get it from:

Libraries-->Applicationsupport-->iphone simulator-->4.3(its ur simulator version)-->applications-->then u can see many files like 0CD04F.... find out your application file through open it.

You can copy the file to your system(which system simulator u need run ) location Libraries-->Applicationsupport-->iphone simulator-->4.3(its your simulator version)-->applications-->

Then open the simulator 4.3 (its your simulator version where you pasted). You can see the application installed there.

Getting from other people:

Please tell them to find out Libraries-->Applicationsupport-->iphone simulator-->4.3(its ur simulator version)-->applications-->then you can see many files like 0CD04F.... from their system and receive that file from them.

After they have got the file, please copy and paste the file in to your system `Libraries-->Applicationsupport-->iphone simulator-->4.3(its your simulator version)-->applications-->(paste the file here).

Then you can see the app is installed in your system simulator and you can run it after clicking the file.

Use mouse_event or keybd_event. They say not to use them anymore but you don't have to find the window at all.

using System;
using System.Runtime.InteropServices;

public class SimulatePCControl
{

[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern void keybd_event(uint bVk, uint bScan, uint dwFlags, uint dwExtraInfo);

private const int VK_LEFT = 0x25;

public static void LeftArrow()
{
    keybd_event(VK_LEFT, 0, 0, 0);
}

}

Virtual Key Codes are here for this one: http://www.kbdedit.com/manual/low_level_vk_list.html

Also for mouse:

using System.Runtime.InteropServices;
using UnityEngine;

public class SimulateMouseClick
{
[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint cButtons, uint dwExtraInfo);
//Mouse actions
private const int MOUSEEVENTF_LEFTDOWN = 0x02;
private const int MOUSEEVENTF_LEFTUP = 0x04;
private const int MOUSEEVENTF_RIGHTDOWN = 0x08;
private const int MOUSEEVENTF_RIGHTUP = 0x10;

public static void Click()
{
    //Call the imported function with the cursor's current position
    uint X = (uint)0;
    uint Y = (uint)0;
    mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, X, Y, 0, 0);
    Debug.LogError("SIMULATED A MOUSE CLICK JUST NOW...");
}

//...other code needed for the application
}

Besides the window resize functions mentioned it is important to understand that the resize events fire a lot if used without a deboucing the events.

Paul Irish has an excellent function that debounces the resize calls a great deal. Very recommended to use. Works cross-browser. Tested it in IE8 the other day and all was fine.

http://www.paulirish.com/2009/throttled-smartresize-jquery-event-handler/

Make sure to check out the demo to see the difference.

Here is the function for completeness.

(function($,sr){

  // debouncing function from John Hann
  // http://unscriptable.com/index.php/2009/03/20/debouncing-javascript-methods/
  var debounce = function (func, threshold, execAsap) {
      var timeout;

      return function debounced () {
          var obj = this, args = arguments;
          function delayed () {
              if (!execAsap)
                  func.apply(obj, args);
              timeout = null;
          };

          if (timeout)
              clearTimeout(timeout);
          else if (execAsap)
              func.apply(obj, args);

          timeout = setTimeout(delayed, threshold || 100);
      };
  }
  // smartresize 
  jQuery.fn[sr] = function(fn){  return fn ? this.bind('resize', debounce(fn)) : this.trigger(sr); };

})(jQuery,'smartresize');


// usage:
$(window).smartresize(function(){
  // code that takes it easy...
});

@ Robert: I have tried to adapt your code with a relative path, and created a batch file to run the VBS.

The VBS starts and closes but doesn't launch the macro... Any idea of where the issue could be?

Option Explicit

On Error Resume Next

ExcelMacroExample

Sub ExcelMacroExample() 

  Dim xlApp 
  Dim xlBook 

  Set xlApp = CreateObject("Excel.Application")
  Set objFSO = CreateObject("Scripting.FileSystemObject")
  strFilePath = objFSO.GetAbsolutePathName(".") 
  Set xlBook = xlApp.Workbooks.Open(strFilePath, "Excels\CLIENTES.xlsb") , 0, True) 
  xlApp.Run "open_form"


  Set xlBook = Nothing 
  Set xlApp = Nothing 

End Sub

I removed the "Application.Quit" because my macro is calling a userform taking care of it.

Cheers

EDIT

I have actually worked it out, just in case someone wants to run a userform "alike" a stand alone application:

Issues I was facing:

1 - I did not want to use the Workbook_Open Event as the excel is locked in read only. 2 - The batch command is limited that the fact that (to my knowledge) it cannot call the macro.

I first wrote a macro to launch my userform while hiding the application:

Sub open_form()
 Application.Visible = False
 frmAddClient.Show vbModeless
End Sub

I then created a vbs to launch this macro (doing it with a relative path has been tricky):

dim fso
dim curDir
dim WinScriptHost
set fso = CreateObject("Scripting.FileSystemObject")
curDir = fso.GetAbsolutePathName(".")
set fso = nothing

Set xlObj = CreateObject("Excel.application")
xlObj.Workbooks.Open curDir & "\Excels\CLIENTES.xlsb"
xlObj.Run "open_form"

And I finally did a batch file to execute the VBS...

@echo off
pushd %~dp0
cscript Add_Client.vbs

Note that I have also included the "Set back to visible" in my Userform_QueryClose:

Private Sub cmdClose_Click()
Unload Me
End Sub

Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
    ThisWorkbook.Close SaveChanges:=True
    Application.Visible = True
    Application.Quit
End Sub

Anyway, thanks for your help, and I hope this will help if someone needs it

I wasn't satisfied by any of the answers so far so I wrote a new random float function. It makes bitwise assumptions about the float data type. It still needs a rand() function with at least 15 random bits.

//Returns a random number in the range [0.0f, 1.0f).  Every
//bit of the mantissa is randomized.
float rnd(void){
  //Generate a random number in the range [0.5f, 1.0f).
  unsigned int ret = 0x3F000000 | (0x7FFFFF & ((rand() << 8) ^ rand()));
  unsigned short coinFlips;

  //If the coin is tails, return the number, otherwise
  //divide the random number by two by decrementing the
  //exponent and keep going. The exponent starts at 63.
  //Each loop represents 15 random bits, a.k.a. 'coin flips'.
  #define RND_INNER_LOOP() \
    if( coinFlips & 1 ) break; \
    coinFlips >>= 1; \
    ret -= 0x800000
  for(;;){
    coinFlips = rand();
    RND_INNER_LOOP(); RND_INNER_LOOP(); RND_INNER_LOOP();
    //At this point, the exponent is 60, 45, 30, 15, or 0.
    //If the exponent is 0, then the number equals 0.0f.
    if( ! (ret & 0x3F800000) ) return 0.0f;
    RND_INNER_LOOP(); RND_INNER_LOOP(); RND_INNER_LOOP();
    RND_INNER_LOOP(); RND_INNER_LOOP(); RND_INNER_LOOP();
    RND_INNER_LOOP(); RND_INNER_LOOP(); RND_INNER_LOOP();
    RND_INNER_LOOP(); RND_INNER_LOOP(); RND_INNER_LOOP();
  }
  return *((float *)(&ret));
}

A 2019 answer if you're using .NET Core - use the Nuget ToDataTable library. Advantages:

• Better performance than reflection or using DataTableProxy
• Also creates SqlParameters for use with SQL Server Table-Valued Parameters

Disclaimer - I'm the author of ToDataTable

Performance - I span up some Benchmark .Net tests and included them in the ToDataTable repo. The results were as follows:

Creating a 100,000 Row Datatable:

Reflection                 818.5 ms
DataTableProxy           1,068.8 ms
ToDataTable                449.0 ms

The nextInt() method leaves the \n (end line) symbol and is picked up immediately by nextLine(), skipping over the next input. What you want to do is use nextLine() for everything, and parse it later:

String nextIntString = keyboard.nextLine(); //get the number as a single line
int nextInt = Integer.parseInt(nextIntString); //convert the string to an int

This is by far the easiest way to avoid problems--don't mix your "next" methods. Use only nextLine() and then parse ints or separate words afterwards.

Also, make sure you use only one Scanner if your are only using one terminal for input. That could be another reason for the exception.

Last note: compare a String with the .equals() function, not the == operator.

if (playAgain == "yes"); // Causes problems
if (playAgain.equals("yes")); // Works every time

The C and C++ declaration syntax has repeatedly been described as a failed experiment, by the original designers.

Instead, let's name the type “pointer to Type”; I’ll call it Ptr_:

template< class Type >
using Ptr_ = Type*;

Now Ptr_<char> is a pointer to char.

Ptr_<const char> is a pointer to const char.

And const Ptr_<const char> is a const pointer to const char.

There.

Why can't we do this.

Give the optional argument a default value. In that way, the caller of the function don't necessarily need to pass the value of the argument. The argument takes the default value. And easily that argument becomes optional for the client.

For e.g.

void foo(int a, int b = 0);

Here b is an optional argument.

CREATE TABLE #t

Creates a table that is only visible on and during that CONNECTION the same user who creates another connection will not be able to see table #t from the other connection.

CREATE TABLE ##t

Creates a temporary table visible to other connections. But the table is dropped when the creating connection is ended.

In my case the problem was that a method was defined in some Interface A as default, while its sub-class overrode it as private. Then when the method was called, the java Runtime realized it was calling a private method.

I am still puzzled as to why the compiler didn't complain about the private override..

public interface A {
     default void doStuff() {
         // doing stuff
     }
}

public class B {
     private void doStuff() {
         // do other stuff instead
     }
}

public static final main(String... args) {
    A someB = new B();
    someB.doStuff();
}

I get the same problem with my work computer. The problem is that when you enter localhost it goes to proxy's address not local address you should bypass it follow this steps

Chrome => Settings => Change proxy settings => LAN Settings => check Bypass proxy server for local addresses.

The safest way to have a PDF display instead of download seems to be embedding it using an object or iframe element. There are also 3rd party solutions like Google's PDF viewer.

See Best Way to Embed PDF in HTML for an overview.

There's also DoPDF, a Java based In-browser PDF viewer. I can't speak to its quality but it looks interesting.

Try getting the element with the ID and check if the return value is null:

document.getElementById('some_nonexistent_id') === null

If you're using jQuery, you can do:

$('#some_nonexistent_id').length === 0

For the Admin version, I think this is a more compact way if you have more than one field:

def get_readonly_fields(self, request, obj=None):
    skips = ('sku', 'other_field')
    fields = super(ItemAdmin, self).get_readonly_fields(request, obj)

    if not obj:
        return [field for field in fields if not field in skips]
    return fields

Its very easy just do the following:

add the following line in your manifest.json

"content_security_policy": "script-src 'self' https://ajax.googleapis.com; object-src 'self'",

Now you are free to load jQuery directly from url

  <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>

If you dataframe is df you can simply use:

import matplotlib.pyplot as plt
import seaborn as sns

plt.figure(figsize=(15, 10))
sns.heatmap(df.corr(), annot=True)

It throws error.

I Resolved it by cloning my project directly into Eclipse from GIT,

Initially I was cloning it at specific location on file system then importing it as existing project into Eclipse.

If you are using large table and want to access of 10 percent of the data then run this following command: SELECT TOP 10 PERCENT * FROM Table1 ORDER BY NEWID();

If you're using .NET version 3.0 or lower, you have to use XmlDocument aka the classic DOM API. Likewise you'll find there are some other APIs which will expect this.

If you get the choice, however, I would thoroughly recommend using XDocument aka LINQ to XML. It's much simpler to create documents and process them. For example, it's the difference between:

XmlDocument doc = new XmlDocument();
XmlElement root = doc.CreateElement("root");
root.SetAttribute("name", "value");
XmlElement child = doc.CreateElement("child");
child.InnerText = "text node";
root.AppendChild(child);
doc.AppendChild(root);

and

XDocument doc = new XDocument(
    new XElement("root",
                 new XAttribute("name", "value"),
                 new XElement("child", "text node")));

Namespaces are pretty easy to work with in LINQ to XML, unlike any other XML API I've ever seen:

XNamespace ns = "http://somewhere.com";
XElement element = new XElement(ns + "elementName");
// etc

LINQ to XML also works really well with LINQ - its construction model allows you to build elements with sequences of sub-elements really easily:

// Customers is a List<Customer>
XElement customersElement = new XElement("customers",
    customers.Select(c => new XElement("customer",
        new XAttribute("name", c.Name),
        new XAttribute("lastSeen", c.LastOrder)
        new XElement("address",
            new XAttribute("town", c.Town),
            new XAttribute("firstline", c.Address1),
            // etc
    ));

It's all a lot more declarative, which fits in with the general LINQ style.

Now as Brannon mentioned, these are in-memory APIs rather than streaming ones (although XStreamingElement supports lazy output). XmlReader and XmlWriter are the normal ways of streaming XML in .NET, but you can mix all the APIs to some extent. For example, you can stream a large document but use LINQ to XML by positioning an XmlReader at the start of an element, reading an XElement from it and processing it, then moving on to the next element etc. There are various blog posts about this technique, here's one I found with a quick search.

I agree with Joris; it seems like you should be doing this differently, like with numpy record arrays. Modifying "option 2" from this great answer, you could do it like this:

import pandas
import numpy

dtype = [('Col1','int32'), ('Col2','float32'), ('Col3','float32')]
values = numpy.zeros(20, dtype=dtype)
index = ['Row'+str(i) for i in range(1, len(values)+1)]

df = pandas.DataFrame(values, index=index)

You need module.exports:

Exports

An object which is shared between all instances of the current module and made accessible through require(). exports is the same as the module.exports object. See src/node.js for more information. exports isn't actually a global but rather local to each module.

For example, if you would like to expose variableName with value "variableValue" on sourceFile.js then you can either set the entire exports as such:

module.exports = { variableName: "variableValue" };

Or you can set the individual value with:

module.exports.variableName = "variableValue";

To consume that value in another file, you need to require(...) it first (with relative pathing):

const sourceFile = require('./sourceFile');
console.log(sourceFile.variableName);

Alternatively, you can deconstruct it.

const { variableName } = require('./sourceFile');
//            current directory --^
// ../     would be one directory down
// ../../  is two directories down

If all you want out of the file is variableName then

./sourceFile.js:

const variableName = 'variableValue'
module.exports = variableName

./consumer.js:

const variableName = require('./sourceFile')

Edit (2020):

Since Node.js version 8.9.0, you can also use ECMAScript Modules with varying levels of support. The documentation.

• For Node v13.9.0 and beyond, experimental modules are enabled by default
• For versions of Node less than version 13.9.0, use --experimental-modules

Node.js will treat the following as ES modules when passed to node as the initial input, or when referenced by import statements within ES module code:

• Files ending in .mjs.

• Files ending in .js when the nearest parent package.json file contains a top-level field "type" with a value of "module".
• Strings passed in as an argument to --eval or --print, or piped to node via STDIN, with the flag --input-type=module.

Once you have it setup, you can use import and export.

Using the example above, there are two approaches you can take

./sourceFile.js:

// This is a named export of variableName
export const variableName = 'variableValue'
// Alternatively, you could have exported it as a default. 
// For sake of explanation, I'm wrapping the variable in an object
// but it is not necessary. 
// You can actually omit declaring what variableName is here. 
// { variableName } is equivalent to { variableName: variableName } in this case. 
export default { variableName: variableName } 

./consumer.js:

// There are three ways of importing. 
// If you need access to a non-default export, then 
// you use { nameOfExportedVariable } 
import { variableName } from './sourceFile'
console.log(variableName) // 'variableValue'

// Otherwise, you simply provide a local variable name 
// for what was exported as default.
import sourceFile from './sourceFile'
console.log(sourceFile.variableName) // 'variableValue'

./sourceFileWithoutDefault.js:

// The third way of importing is for situations where there
// isn't a default export but you want to warehouse everything
// under a single variable. Say you have:
export const a = 'A'
export const b = 'B'

./consumer2.js

// Then you can import all exports under a single variable
// with the usage of * as:
import * as sourceFileWithoutDefault from './sourceFileWithoutDefault'

console.log(sourceFileWithoutDefault.a) // 'A'
console.log(sourceFileWithoutDefault.b) // 'B'

// You can use this approach even if there is a default export:
import * as sourceFile from './sourceFile'

// Default exports are under the variable default:
console.log(sourceFile.default) // { variableName: 'variableValue' }

// As well as named exports:
console.log(sourceFile.variableName) // 'variableValue

If your XSLT processor supports EXSLT, you can use str:tokenize, otherwise, the link contains an implementation using functions like substring-before.

This might help you.

alert(ParentID.id); 

Just add weightSum tag to linearlayout to 1 and for the corresponding view beneath it give layout_weight as .9 it will create a space between the views. You can experiment with the values to get appropriate value for you.

HTTP Basic + HTTPS is one common method.

we can store data in session and can use it anywhere in out program.

$window.sessionStorage.setItem("Mydata",data);

Other place

$scope.data = $window.sessionStorage.getItem("Mydata");

This is not valid TypeScript code. You can not have method invocations in the body of a class.

// INVALID CODE
export class AppComponent {
  public n: number = 1;
  setTimeout(function() {
    n = n + 10;
  }, 1000);
}

Instead move the setTimeout call to the constructor of the class. Additionally, use the arrow function => to gain access to this.

export class AppComponent {
  public n: number = 1;

  constructor() {
    setTimeout(() => {
      this.n = this.n + 10;
    }, 1000);
  }

}

In TypeScript, you can only refer to class properties or methods via this. That's why the arrow function => is important.

You can convert directly via the String(byte[], String) constructor and getBytes(String) method. Java exposes available character sets via the Charset class. The JDK documentation lists supported encodings.

90% of the time, such conversions are performed on streams, so you'd use the Reader/Writer classes. You would not incrementally decode using the String methods on arbitrary byte streams - you would leave yourself open to bugs involving multibyte characters.

You should use some HTML parsing library like lxml:

from lxml import etree
s = """<table>
  <tr><th>Event</th><th>Start Date</th><th>End Date</th></tr>
  <tr><td>a</td><td>b</td><td>c</td></tr>
  <tr><td>d</td><td>e</td><td>f</td></tr>
  <tr><td>g</td><td>h</td><td>i</td></tr>
</table>
"""
table = etree.HTML(s).find("body/table")
rows = iter(table)
headers = [col.text for col in next(rows)]
for row in rows:
    values = [col.text for col in row]
    print dict(zip(headers, values))

prints

{'End Date': 'c', 'Start Date': 'b', 'Event': 'a'}
{'End Date': 'f', 'Start Date': 'e', 'Event': 'd'}
{'End Date': 'i', 'Start Date': 'h', 'Event': 'g'}

int x = thisObject.compareTo(anotherObject);

The compareTo() method returns an int with the following characteristics:

• negative If thisObject < anotherObject
• zero If thisObject == anotherObject
• positive If thisObject > anotherObject

On your aspx page define the HTML Button element with the usual suspects: runat, class, title, etc.

If this element is part of a data bound control (i.e.: grid view, etc.) you may want to use CommandName and possibly CommandArgument as attributes. Add your button's content and closing tag.

<button id="cmdAction" 
    runat="server" onserverclick="cmdAction_Click()" 
    class="Button Styles" 
    title="Does something on the server" 
    <!-- for databound controls -->
    CommandName="cmdname"> 
    CommandArgument="args..."
    >
    <!-- content -->
    <span class="ui-icon ..."></span>
    <span class="push">Click Me</span>
</button>

On the code behind page the element would call the handler that would be defined as the element's ID_Click event function.

protected void cmdAction_Click(object sender, EventArgs e)
{
: do something.
}

There are other solutions as in using custom controls, etc. Also note that I am using this live on projects in VS2K8.

Hoping this helps. Enjoy!

Overall:You persist entity that is violating database rules like as saving entity that has varchar field over 250 chars ,something like that.

In my case it was a squishy problem with TestEntityManager ,because it use HSQL database /in memory database/ and it persist the user but when you try to find it ,it drops the same exception :/

@RunWith(SpringRunner.class)
@ContextConfiguration(classes= Application.class)
@DataJpaTest
@ActiveProfiles("test")
public class UserServicesTests {

@Autowired
private TestEntityManager testEntityManager;

@Autowired
private UserRepository userRepository;

@Test
public void oops() {
    User user = new User();
    user.setUsername("Toshko");
    //EMAIL IS REQUIRED:
    //user.setEmail("OPS");
    this.testEntityManager.persist(user);

    //HERE COMES TE EXCEPTION BECAUSE THE EMAIL FIELD IN TE DATABASE IS REQUIRED :
    this.userRepository.findUserByUsername("Toshko");

    System.out.println();
}
}

Not possible, I believe ie has a content changed event but it is certainly not x-browser

Should I say not possible without some nasty interval chugging away in the background!

Here is an example of how to use strtok borrowed from MSDN.

And the relevant bits, you need to call it multiple times. The token char* is the part you would stuff into an array (you can figure that part out).

char string[] = "A string\tof ,,tokens\nand some  more tokens";
char seps[]   = " ,\t\n";
char *token;

int main( void )
{
    printf( "Tokens:\n" );
    /* Establish string and get the first token: */
    token = strtok( string, seps );
    while( token != NULL )
    {
        /* While there are tokens in "string" */
        printf( " %s\n", token );
        /* Get next token: */
        token = strtok( NULL, seps );
    }
}

For swift3

If you just want to call the method, run the code below.

self.delegate?.method?()

The getActionCommand() method returns an String associated with that Component set through the setActionCommand() , whereas the getSource() method returns an Object of the Object class specifying the source of the event.
