Quick Answer:

In a single line, the curl command would be:

a) If sending form data:

curl -X PUT -H "Content-Type: multipart/form-data;" -F "key1=val1" "YOUR_URI"

b) If sending raw data as json:

curl -X PUT -H "Content-Type: application/json" -d '{"key1":"value"}' "YOUR_URI"

c) If sending a file with a POST request:

curl -X POST "YOUR_URI" -F 'file=@/file-path.csv'

Alternative solution:

You can use the POSTMAN app from Chrome Store to get the equivalent cURL request. This is especially useful when writing more complicated requests.

For the request with other formats or for different clients like java, PHP, you can check out POSTMAN/comment below.

My best guess is that this is not a bug, but a feature of Sql 2012. ;-) In other contexts, you'd be happy to retain your cr-lf's, like when copying a big chunk of text. It's just that it doesn't work well in your situation.

You could always strip them out in your select. This would make your query for as you intend in both versions:

select REPLACE(col, CHAR(13) + CHAR(10), ', ') from table

This can also be caused if you include bootstrap.js before jquery.js.

Others might have the same problem I did.

Include jQuery before bootstrap.

I had similar json response coming from client. Created one main list class, and one POJO class.

You don't quite have SQL Server's proprietary UPDATE FROM syntax down. Also not sure why you needed to join on the CommonField and also filter on it afterward. Try this:

UPDATE t1
  SET t1.CalculatedColumn = t2.[Calculated Column]
  FROM dbo.Table1 AS t1
  INNER JOIN dbo.Table2 AS t2
  ON t1.CommonField = t2.[Common Field]
  WHERE t1.BatchNo = '110';

If you're doing something really silly - like constantly trying to set the value of one column to the aggregate of another column (which violates the principle of avoiding storing redundant data), you can use a CTE (common table expression) - see here and here for more details:

;WITH t2 AS
(
  SELECT [key], CalculatedColumn = SUM(some_column)
    FROM dbo.table2
    GROUP BY [key]
)
UPDATE t1
  SET t1.CalculatedColumn = t2.CalculatedColumn
  FROM dbo.table1 AS t1
  INNER JOIN t2
  ON t1.[key] = t2.[key];

The reason this is really silly, is that you're going to have to re-run this entire update every single time any row in table2 changes. A SUM is something you can always calculate at runtime and, in doing so, never have to worry that the result is stale.

This happened to me when I had a class in one jar trying to access a private method in a class from another jar. I simply changed the private method to public, recompiled and deployed, and it worked ok afterwards.

There is a read_pickle function as part of pandas 0.22+

import pandas as pd

object = pd.read_pickle(r'filepath')

look the compileSdkVersion at android/biuld.gradle ,and compileSdkVersion in all other packages should be the same.

It's a one-liner with mutate_at:

dat %>% mutate_at("l1", factor) %>% mutate_at("l2", as.numeric)

The traceback module and sys.exc_info are overkill for tracking down the source of an exception. That's all in the default traceback. So instead of calling exit(1) just re-raise:

try:
    assert "birthday cake" == "ice cream cake", "Should've asked for pie"
except AssertionError:
    print 'Houston, we have a problem.'
    raise

Which gives the following output that includes the offending statement and line number:

Houston, we have a problem.
Traceback (most recent call last):
  File "/tmp/poop.py", line 2, in <module>
    assert "birthday cake" == "ice cream cake", "Should've asked for pie"
AssertionError: Should've asked for pie

Similarly the logging module makes it easy to log a traceback for any exception (including those which are caught and never re-raised):

import logging

try:
    assert False == True 
except AssertionError:
    logging.error("Nothing is real but I can't quit...", exc_info=True)

You could do this:

if( ctrl[0].nodeName.toLowerCase() === 'input' ) {
    // it was an input
}

or this, which is slower, but shorter and cleaner:

if( ctrl.is('input') ) {
    // it was an input
}

If you want to be more specific, you can test the type:

if( ctrl.is('input:text') ) {
    // it was an input
}

I had let this go for a good while but revisited it later. Since this question is viewed regularly. This is eventually what I ended up using that worked for me.

define("DOC_ROOT","/path/to/html");
//username and password of account
$username = trim($values["email"]);
$password = trim($values["password"]);

//set the directory for the cookie using defined document root var
$path = DOC_ROOT."/ctemp";
//build a unique path with every request to store. the info per user with custom func. I used this function to build unique paths based on member ID, that was for my use case. It can be a regular dir.
//$path = build_unique_path($path); // this was for my use case

//login form action url
$url="https://www.example.com/login/action"; 
$postinfo = "email=".$username."&password=".$password;

$cookie_file_path = $path."/cookie.txt";

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_NOBODY, false);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);
//set the cookie the site has for certain features, this is optional
curl_setopt($ch, CURLOPT_COOKIE, "cookiename=0");
curl_setopt($ch, CURLOPT_USERAGENT,

curl_setopt($ch, CURLOPT_REFERER, $_SERVER['REQUEST_URI']);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

curl_setopt($ch, CURLOPT_POST, 1);

curl_exec($ch);

curl_setopt($ch, CURLOPT_URL, "http://www.example.com/page/");
//do stuff with the info with DomDocument() etc
$html = curl_exec($ch);
curl_close($ch);

Update: This code was never meant to be a copy and paste. It was to show how I used it for my specific use case. You should adapt it to your code as needed. Such as directories, vars etc

These are bitwise shift operators.

Quoting from the docs:

x << y

Returns x with the bits shifted to the left by y places (and new bits on the right-hand-side are zeros). This is the same as multiplying x by 2**y.

x >> y

Returns x with the bits shifted to the right by y places. This is the same as dividing x by 2**y.

Use next, it will bypass that condition and rest of the code will work. Below i have provided the Full script and out put

class TestBreak
  puts " Enter the nmber"
  no= gets.to_i
  for i in 1..no
    if(i==5)
      next
    else 
      puts i
    end
  end
end

obj=TestBreak.new()

Output: Enter the nmber 10

1 2 3 4 6 7 8 9 10

I have pulled my hair out with this error a few time. I have managed to make it sometime disappear by restarting Apache/Nginx.

So I fixed it the same way as above, by adding the following to the GEM file:

gem 'execjs'
gem 'therubyracer', :platforms => :ruby

and then I DELETED my gemfile.lock file and then reran "bundle install". I found only then did "bundle install" actually install the correct libraries etc.

Use this XPath expression:

/*/*/X/node()

This selects any node (element, text node, comment or processing instruction) that is a child of any X element that is a grand-child of the top element of the XML document.

To verify what is selected, here is this XSLT transformation that outputs exactly the selected nodes:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes"/>
 <xsl:template match="/">
  <xsl:copy-of select="/*/*/X/node()"/>
 </xsl:template>
</xsl:stylesheet>

and it produces exactly the wanted, correct result:

   First Text Node #1            
    <y> Y can Have Child Nodes #                
        <child> deep to it </child>
    </y>            Second Text Node #2 
    <z />

Explanation:

1. As defined in the W3 XPath 1.0 Spec, "child::node() selects all the children of the context node, whatever their node type." This means that any element, text-node, comment-node and processing-instruction node children are selected by this node-test.

2. node() is an abbreviation of child::node() (because child:: is the primary axis and is used when no axis is explicitly specified).

Try this (using "Results to text"):

SELECT
ISNULL(smsp.definition, ssmsp.definition) AS [Definition]
FROM
sys.all_objects AS sp
LEFT OUTER JOIN sys.sql_modules AS smsp ON smsp.object_id = sp.object_id
LEFT OUTER JOIN sys.system_sql_modules AS ssmsp ON ssmsp.object_id = sp.object_id
WHERE
(sp.type = N'V' OR sp.type = N'P' OR sp.type = N'RF' OR sp.type=N'PC')and(sp.name=N'YourObjectName' and SCHEMA_NAME(sp.schema_id)=N'dbo')

The following code center the Window in the center of the current monitor (ie where the mouse pointer is located).

public static final void centerWindow(final Window window) {
    GraphicsDevice screen = MouseInfo.getPointerInfo().getDevice();
    Rectangle r = screen.getDefaultConfiguration().getBounds();
    int x = (r.width - window.getWidth()) / 2 + r.x;
    int y = (r.height - window.getHeight()) / 2 + r.y;
    window.setLocation(x, y);
}

You need to use the local set command below:

local set

git config user.email [email protected]
git config user.name 'Mahmoud Zalt'

local get

git config --get user.email
git config --get user.name

The local config file is in the project directory: .git/config.

global set

git config --global user.email [email protected]
git config --global user.name 'Mahmoud Zalt'

global get

git config --global --get user.email
git config --global --get user.name

The global config file in in your home directory: ~/.gitconfig.

Remember to quote blanks, etc, for example: 'FirstName LastName'

Among many others already covered in the many answers, I would highlight that SOAP enables to define a contract, the WSDL, which define the operations supported, complex types, etc. SOAP is oriented to operations, but REST is oriented at resources. Personally I would select SOAP for complex interfaces between internal enterprise applications, and REST for public, simpler, stateless interfaces with the outside world.

Here is an example of a javascript function that can generate a random number of any specified length without using Math.random():

    function genRandom(length)
    {
     const t1 = new Date().getMilliseconds();
     var min = "1",max = "9";
     var result;
     var numLength = length;
     if (numLength != 0)
     {
        for (var i = 1; i < numLength; i++)
        {
           min = min.toString() + "0";
           max = max.toString() + "9";
        }
     } 
     else
     {
        min = 0;
        max = 0;
        return; 
     }

      for (var i = min; i <= max; i++)
      {
           //Empty Loop
      }

      const t2 = new Date().getMilliseconds();
      console.log(t2);
      result = ((max - min)*t1)/t2;
      console.log(result);
      return result;
    }

Use the method .rdd like this:

rdd = df.rdd

I think that once you've imported it, the behaviour is the same (in the place your variable will be used outside source file).

The only difference would be if you try to reassign it before the end of this very file.

It happens more often than not, I am on a slow internet connection and I have to clone a decently-huge git repository. The most common issue is that the connection closes and the whole clone is cancelled.

Cloning into 'large-repository'...
remote: Counting objects: 20248, done.
remote: Compressing objects: 100% (10204/10204), done.
error: RPC failed; curl 18 transfer closed with outstanding read data remaining 
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed

After a lot of trial and errors and a lot of “remote end hung up unexpectedly” I have a way that works for me. The idea is to do a shallow clone first and then update the repository with its history.

$ git clone http://github.com/large-repository --depth 1
$ cd large-repository
$ git fetch --unshallow

The accepted answer correctly addresses the OP's question based on his example. However, it only applies when ToList is applied to a concrete collection; it does not hold when the elements of the source sequence have yet to be instantiated (due to deferred execution). In case of the latter, you might get a new set of items each time you call ToList (or enumerate the sequence).

Here is an adaptation of the OP's code to demonstrate this behaviour:

public static void RunChangeList()
{
    var objs = Enumerable.Range(0, 10).Select(_ => new MyObject() { SimpleInt = 0 });
    var whatInt = ChangeToList(objs);   // whatInt gets 0
}

public static int ChangeToList(IEnumerable<MyObject> objects)
{
    var objectList = objects.ToList();
    objectList.First().SimpleInt = 5;
    return objects.First().SimpleInt;
}

Whilst the above code may appear contrived, this behaviour can appear as a subtle bug in other scenarios. See my other example for a situation where it causes tasks to get spawned repeatedly.

Old, but maybe useful for readers to have a full example of how use modal.

I do like following ( working example jsfiddle ) :

$('button.btn.btn-success').click(function(event)
{

event.preventDefault();

$.post('getpostcodescript.php', $('form').serialize(), function(data, status, xhr)
    {
        // do something here with response;
        console.info(data);
        console.info(status);
        console.info(xhr);
    })
    .done(function() {
        // do something here if done ;
        alert( "saved" );
    })
    .fail(function() {
        // do something here if there is an error ;
        alert( "error" );
    })
    .always(function() {
        // maybe the good state to close the modal
        alert( "finished" );
        // Set a timeout to hide the element again
        setTimeout(function(){
          $("#myModal").hide();
        }, 3000);
    });
});

To deal easier with modals, I recommend using eModal, which permit to go faster on base use of bootstrap 3 modals.

Try a conditional group matching 50-99 or any string of three or more digits:

var r = /^(?:[5-9]\d|\d{3,})$/

You could even do it like this:

Example

grep -rl 'windows' ./ | xargs sed -i 's/windows/linux/g'

This will search for the string 'windows' in all files relative to the current directory and replace 'windows' with 'linux' for each occurrence of the string in each file.

Adding the following lines in "~/.bashrc" solved the issue for me. I'm using Ubuntu 14.04 desktop.

eval `gnome-keyring-daemon --start`
USERNAME="reynold"
export SSH_AUTH_SOCK="$(ls /run/user/$(id -u $USERNAME)/keyring*/ssh|head -1)"
export SSH_AGENT_PID="$(pgrep gnome-keyring)"

You can either copy files into the folder where external partition is located or use

INSERT OVERWRITE TABLE tablename1 PARTITION (partcol1=val1, partcol2=val2...)...

statement.

If x^2 and y^2 were expressions already given in the variable squared, this solves the problem:

labNames <- c('xLab','yLab')
squared <- c(expression('x'^2), expression('y'^2))

xlab <- eval(bquote(expression(.(labNames[1]) ~ .(squared[1][[1]]))))
ylab <- eval(bquote(expression(.(labNames[2]) ~ .(squared[2][[1]]))))

plot(c(1:10), xlab = xlab, ylab = ylab)

Please note the [[1]] behind squared[1]. It gives you the content of "expression(...)" between the brackets without any escape characters.

This should fulfill your requirements.

Here is an example showing some text in circles with data from a json file: http://bl.ocks.org/4474971. Which gives the following:

The main idea behind this is to encapsulate the text and the circle in the same "div" as you would do in html to have the logo and the name of the company in the same div in a page header.

The main code is:

var width = 960,
    height = 500;

var svg = d3.select("body").append("svg")
    .attr("width", width)
    .attr("height", height)

d3.json("data.json", function(json) {
    /* Define the data for the circles */
    var elem = svg.selectAll("g")
        .data(json.nodes)

    /*Create and place the "blocks" containing the circle and the text */  
    var elemEnter = elem.enter()
        .append("g")
        .attr("transform", function(d){return "translate("+d.x+",80)"})

    /*Create the circle for each block */
    var circle = elemEnter.append("circle")
        .attr("r", function(d){return d.r} )
        .attr("stroke","black")
        .attr("fill", "white")

    /* Create the text for each block */
    elemEnter.append("text")
        .attr("dx", function(d){return -20})
        .text(function(d){return d.label})
})

and the json file is:

{"nodes":[
  {"x":80, "r":40, "label":"Node 1"}, 
  {"x":200, "r":60, "label":"Node 2"}, 
  {"x":380, "r":80, "label":"Node 3"}
]}

The resulting html code shows the encapsulation you want:

<svg width="960" height="500">
    <g transform="translate(80,80)">
        <circle r="40" stroke="black" fill="white"></circle>
        <text dx="-20">Node 1</text>
    </g>
    <g transform="translate(200,80)">
        <circle r="60" stroke="black" fill="white"></circle>
        <text dx="-20">Node 2</text>
    </g>
    <g transform="translate(380,80)">
        <circle r="80" stroke="black" fill="white"></circle>
        <text dx="-20">Node 3</text>
    </g>
</svg>

DECLARE @yourSpecialMark = '/';

It will count, how many times occours the special mark '/'

myDivObj = document.getElementById("myDiv");
if ( myDivObj ) {
   alert ( myDivObj.innerHTML ); 
}else{
   alert ( "Alien Found" );
}

Above code will show the innerHTML, i.e if you have used html tags inside div then it will show even those too. probably this is not what you expected. So another solution is to use: innerText / textContent property [ thanx to bobince, see his comment ]

function showDivText(){
            divObj = document.getElementById("myDiv");
            if ( divObj ){
                if ( divObj.textContent ){ // FF
                    alert ( divObj.textContent );
                }else{  // IE           
                    alert ( divObj.innerText );  //alert ( divObj.innerHTML );
                } 
            }  
        }

In my opinion, no answer covers all edge cases as parsing a float should result in an error.

function parseInteger(value) {
    if(value === '') return NaN;
    const number = Number(value);
    return Number.isInteger(number) ? number : NaN;
}

parseInteger("4")            // 4
parseInteger("5aaa")         // NaN
parseInteger("4.33333")      // NaN
parseInteger("aaa");         // NaN

you have to use this css property,

 position:relative;

use it for your #contentframe div tag

User data is very important for a good developer, so don't ask again and again for same data, use some logic to correct some basic error in data.

Before validation of Email: First you have to remove all illegal characters from email.

//This will Remove all illegal characters from email
$email = filter_var($email, FILTER_SANITIZE_EMAIL);

after that validate your email address using this filter_var() function.

filter_var($email, FILTER_VALIDATE_EMAIL)) // To Validate the email

For e.g.

<?php
$email = "[email protected]";

// Remove all illegal characters from email
$email = filter_var($email, FILTER_SANITIZE_EMAIL);

// Validate email
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
    echo $email." is a valid email address";
} else {
    echo $email." is not a valid email address";
}
?>

On my server, the nginx cache folder is at /data/nginx/cache/

So I removed it only: sudo rm -rf /data/nginx/cache/

Hope this will help anyone.

The solution is actually a lot easier than any of the other suggestions:

std::wstring stemp = std::wstring(s.begin(), s.end());
LPCWSTR sw = stemp.c_str();

Best of all, it's platform independent.

A - How To Reverse A Stack

To understand how to construct a queue using two stacks, you should understand how to reverse a stack crystal clear. Remember how stack works, it is very similar to the dish stack on your kitchen. The last washed dish will be on the top of the clean stack, which is called as Last In First Out (LIFO) in computer science.

Lets imagine our stack like a bottle as below;

If we push integers 1,2,3 respectively, then 3 will be on the top of the stack. Because 1 will be pushed first, then 2 will be put on the top of 1. Lastly, 3 will be put on the top of the stack and latest state of our stack represented as a bottle will be as below;

Now we have our stack represented as a bottle is populated with values 3,2,1. And we want to reverse the stack so that the top element of the stack will be 1 and bottom element of the stack will be 3. What we can do ? We can take the bottle and hold it upside down so that all the values should reverse in order ?

Yes we can do that, but that's a bottle. To do the same process, we need to have a second stack that which is going to store the first stack elements in reverse order. Let's put our populated stack to the left and our new empty stack to the right. To reverse the order of the elements, we are going to pop each element from left stack, and push them to the right stack. You can see what happens as we do so on the image below;

So we know how to reverse a stack.

B - Using Two Stacks As A Queue

On previous part, I've explained how can we reverse the order of stack elements. This was important, because if we push and pop elements to the stack, the output will be exactly in reverse order of a queue. Thinking on an example, let's push the array of integers {1, 2, 3, 4, 5} to a stack. If we pop the elements and print them until the stack is empty, we will get the array in the reverse order of pushing order, which will be {5, 4, 3, 2, 1} Remember that for the same input, if we dequeue the queue until the queue is empty, the output will be {1, 2, 3, 4, 5}. So it is obvious that for the same input order of elements, output of the queue is exactly reverse of the output of a stack. As we know how to reverse a stack using an extra stack, we can construct a queue using two stacks.

Our queue model will consist of two stacks. One stack will be used for enqueue operation (stack #1 on the left, will be called as Input Stack), another stack will be used for the dequeue operation (stack #2 on the right, will be called as Output Stack). Check out the image below;

Our pseudo-code is as below;

Enqueue Operation

Push every input element to the Input Stack

Dequeue Operation

If ( Output Stack is Empty)
    pop every element in the Input Stack
    and push them to the Output Stack until Input Stack is Empty

pop from Output Stack

Let's enqueue the integers {1, 2, 3} respectively. Integers will be pushed on the Input Stack (Stack #1) which is located on the left;

Then what will happen if we execute a dequeue operation? Whenever a dequeue operation is executed, queue is going to check if the Output Stack is empty or not(see the pseudo-code above) If the Output Stack is empty, then the Input Stack is going to be extracted on the output so the elements of Input Stack will be reversed. Before returning a value, the state of the queue will be as below;

Check out the order of elements in the Output Stack (Stack #2). It's obvious that we can pop the elements from the Output Stack so that the output will be same as if we dequeued from a queue. Thus, if we execute two dequeue operations, first we will get {1, 2} respectively. Then element 3 will be the only element of the Output Stack, and the Input Stack will be empty. If we enqueue the elements 4 and 5, then the state of the queue will be as follows;

Now the Output Stack is not empty, and if we execute a dequeue operation, only 3 will be popped out from the Output Stack. Then the state will be seen as below;

Again, if we execute two more dequeue operations, on the first dequeue operation, queue will check if the Output Stack is empty, which is true. Then pop out the elements of the Input Stack and push them to the Output Stack unti the Input Stack is empty, then the state of the Queue will be as below;

Easy to see, the output of the two dequeue operations will be {4, 5}

C - Implementation Of Queue Constructed with Two Stacks

Here is an implementation in Java. I'm not going to use the existing implementation of Stack so the example here is going to reinvent the wheel;

C - 1) MyStack class : A Simple Stack Implementation

public class MyStack<T> {

    // inner generic Node class
    private class Node<T> {
        T data;
        Node<T> next;

        public Node(T data) {
            this.data = data;
        }
    }

    private Node<T> head;
    private int size;

    public void push(T e) {
        Node<T> newElem = new Node(e);

        if(head == null) {
            head = newElem;
        } else {
            newElem.next = head;
            head = newElem;     // new elem on the top of the stack
        }

        size++;
    }

    public T pop() {
        if(head == null)
            return null;

        T elem = head.data;
        head = head.next;   // top of the stack is head.next

        size--;

        return elem;
    }

    public int size() {
        return size;
    }

    public boolean isEmpty() {
        return size == 0;
    }

    public void printStack() {
        System.out.print("Stack: ");

        if(size == 0)
            System.out.print("Empty !");
        else
            for(Node<T> temp = head; temp != null; temp = temp.next)
                System.out.printf("%s ", temp.data);

        System.out.printf("\n");
    }
}

C - 2) MyQueue class : Queue Implementation Using Two Stacks

public class MyQueue<T> {

    private MyStack<T> inputStack;      // for enqueue
    private MyStack<T> outputStack;     // for dequeue
    private int size;

    public MyQueue() {
        inputStack = new MyStack<>();
        outputStack = new MyStack<>();
    }

    public void enqueue(T e) {
        inputStack.push(e);
        size++;
    }

    public T dequeue() {
        // fill out all the Input if output stack is empty
        if(outputStack.isEmpty())
            while(!inputStack.isEmpty())
                outputStack.push(inputStack.pop());

        T temp = null;
        if(!outputStack.isEmpty()) {
            temp = outputStack.pop();
            size--;
        }

        return temp;
    }

    public int size() {
        return size;
    }

    public boolean isEmpty() {
        return size == 0;
    }

}

C - 3) Demo Code

public class TestMyQueue {

    public static void main(String[] args) {
        MyQueue<Integer> queue = new MyQueue<>();

        // enqueue integers 1..3
        for(int i = 1; i <= 3; i++)
            queue.enqueue(i);

        // execute 2 dequeue operations 
        for(int i = 0; i < 2; i++)
            System.out.println("Dequeued: " + queue.dequeue());

        // enqueue integers 4..5
        for(int i = 4; i <= 5; i++)
            queue.enqueue(i);

        // dequeue the rest
        while(!queue.isEmpty())
            System.out.println("Dequeued: " + queue.dequeue());
    }

}

C - 4) Sample Output

Dequeued: 1
Dequeued: 2
Dequeued: 3
Dequeued: 4
Dequeued: 5

objectForKey: is an NSDictionary method. An NSDictionary is a collection class similar to an NSArray, except instead of using indexes, it uses keys to differentiate between items. A key is an arbitrary string you provide. No two objects can have the same key (just as no two objects in an NSArray can have the same index).

valueForKey: is a KVC method. It works with ANY class. valueForKey: allows you to access a property using a string for its name. So for instance, if I have an Account class with a property accountNumber, I can do the following:

NSNumber *anAccountNumber = [NSNumber numberWithInt:12345];
Account *newAccount = [[Account alloc] init];

[newAccount setAccountNumber:anAccountNUmber];

NSNumber *anotherAccountNumber = [newAccount accountNumber];

Using KVC, I can access the property dynamically:

NSNumber *anAccountNumber = [NSNumber numberWithInt:12345];
Account *newAccount = [[Account alloc] init];

[newAccount setValue:anAccountNumber forKey:@"accountNumber"];

NSNumber *anotherAccountNumber = [newAccount valueForKey:@"accountNumber"];

Those are equivalent sets of statements.

I know you're thinking: wow, but sarcastically. KVC doesn't look all that useful. In fact, it looks "wordy". But when you want to change things at runtime, you can do lots of cool things that are much more difficult in other languages (but this is beyond the scope of your question).

If you want to learn more about KVC, there are many tutorials if you Google especially at Scott Stevenson's blog. You can also check out the NSKeyValueCoding Protocol Reference.

Hope that helps.

You can try with this code (Same case)

chaine1 + chaine2; 

I suggest you also (I prefer this) the string.concat method

A better solution for this is to

1. Copy/past code of Stored Procedure
2. Join that code with the table for which you want to run it again (for each row)

This was you get a clean table-formatted output. While if you run SP for every row, you get a separate query result for each iteration which is ugly.

For people who wants to load apk from Linux system with React native application running on it. I have given the path in which the android application resides as well. So that those who need to find the apk file can go to view it.

adb -s 434eeads install android/app/build/outputs/apk/debug/app-debug.apk

For reinstalling the android app on phone

adb -s 434eeads install -r android/app/build/outputs/apk/debug/app-debug.apk

-s -> source/serialNumber

r -> Re-install path + file name : android/app/build/outputs/apk/debug/app-debug.apk

It is for react native applications.

Have you escaped your forward slashes( / )? I've had trouble with those before

There is also another easy way to check the latest version without going to NPM if you are using VS Code.

In package.json file check for the module you want to know the latest version. Remove the current version already present there and do CTRL + space or CMD + space(mac).The VS code will show the latest versions

The singe pipe "|" is the "bitwise" or and should only be used when you know what you're doing. The double pipe "||" is a logical or, and can be used in logical statements, like "x == 0 || x == 1".

Here's an example of what the bitwise or does: if a=0101 and b=0011, then a|b=0111. If you're dealing with a logic system that treats any non-zero as true, then the bitwise or will act in the same way as the logical or, but it's counterpart (bitwise and, "&") will NOT. Also the bitwise or does not perform short circuit evaluation.

I've just put together what you may be looking for: http://www.graphdracula.net

It's JavaScript with directed graph layouting, SVG and you can even drag the nodes around. Still needs some tweaking, but is totally usable. You create nodes and edges easily with JavaScript code like this:

var g = new Graph();
g.addEdge("strawberry", "cherry");
g.addEdge("cherry", "apple");
g.addEdge("id34", "cherry");

I used the previously mentioned Raphael JS library (the graffle example) plus some code for a force based graph layout algorithm I found on the net (everything open source, MIT license). If you have any remarks or need a certain feature, I may implement it, just ask!

You may want to have a look at other projects, too! Below are two meta-comparisons:

• SocialCompare has an extensive list of libraries, and the "Node / edge graph" line will filter for graph visualization ones.

• DataVisualization.ch has evaluated many libraries, including node/graph ones. Unfortunately there's no direct link so you'll have to filter for "graph":

Here's a list of similar projects (some have been already mentioned here):

Pure JavaScript Libraries

• vis.js supports many types of network/edge graphs, plus timelines and 2D/3D charts. Auto-layout, auto-clustering, springy physics engine, mobile-friendly, keyboard navigation, hierarchical layout, animation etc. MIT licensed and developed by a Dutch firm specializing in research on self-organizing networks.

• Cytoscape.js - interactive graph analysis and visualization with mobile support, following jQuery conventions. Funded via NIH grants and developed by by @maxkfranz (see his answer below) with help from several universities and other organizations.

• The JavaScript InfoVis Toolkit - Jit, an interactive, multi-purpose graph drawing and layout framework. See for example the Hyperbolic Tree. Built by Twitter dataviz architect Nicolas Garcia Belmonte and bought by Sencha in 2010.

• D3.js Powerful multi-purpose JS visualization library, the successor of Protovis. See the force-directed graph example, and other graph examples in the gallery.

• Plotly's JS visualization library uses D3.js with JS, Python, R, and MATLAB bindings. See a nexworkx example in IPython here, human interaction example here, and JS Embed API.

• sigma.js Lightweight but powerful library for drawing graphs

• jsPlumb jQuery plug-in for creating interactive connected graphs

• Springy - a force-directed graph layout algorithm

• Processing.js Javascript port of the Processing library by John Resig

• JS Graph It - drag'n'drop boxes connected by straight lines. Minimal auto-layout of the lines.

• RaphaelJS's Graffle - interactive graph example of a generic multi-purpose vector drawing library. RaphaelJS can't layout nodes automatically; you'll need another library for that.

• JointJS Core - David Durman's MPL-licensed open source diagramming library. It can be used to create either static diagrams or fully interactive diagramming tools and application builders. Works in browsers supporting SVG. Layout algorithms not-included in the core package

• mxGraph Previously commercial HTML 5 diagramming library, now available under Apache v2.0. mxGraph is the base library used in draw.io.

Commercial libraries

• GoJS Interactive graph drawing and layout library

• yFiles for HTML Commercial graph drawing and layout library

• KeyLines Commercial JS network visualization toolkit

• ZoomCharts Commercial multi-purpose visualization library

• Syncfusion JavaScript Diagram Commercial diagram library for drawing and visualization.

Abandoned libraries

• Cytoscape Web Embeddable JS Network viewer (no new features planned; succeeded by Cytoscape.js)

• Canviz JS renderer for Graphviz graphs. Abandoned in Sep 2013.

• arbor.js Sophisticated graphing with nice physics and eye-candy. Abandoned in May 2012. Several semi-maintained forks exist.

• jssvggraph "The simplest possible force directed graph layout algorithm implemented as a Javascript library that uses SVG objects". Abandoned in 2012.

• jsdot Client side graph drawing application. Abandoned in 2011.

• Protovis Graphical Toolkit for Visualization (JavaScript). Replaced by d3.

• Moo Wheel Interactive JS representation for connections and relations (2008)

• JSViz 2007-era graph visualization script

• dagre Graph layout for JavaScript

Non-Javascript Libraries

• Graphviz Sophisticated graph visualization language

  • Graphviz has been compiled to Javascript using Emscripten here with an online interactive demo here

• Flare Beautiful and powerful Flash based graph drawing

• NodeBox Python Graph Visualization

As mentioned by Quynh Nguyen, you don't need the '.' in the className. However - document.getElementsByClassName('col1') will return an array of objects.

This will return an "undefined" value because an array doesn't have a class. You'll still need to loop through the array elements...

function changeBGColor() {
  var cols = document.getElementsByClassName('col1');
  for(i = 0; i < cols.length; i++) {
    cols[i].style.backgroundColor = 'blue';
  }
}

One special case for this is if you have used a construction like the following in your ~/.muttrc:

# Reset From email to default
send-hook . "my_hdr From: Real Name <[email protected]>"

This send-hook will override either of these:

mutt -e "set [email protected]"
mutt -e "my_hdr From: Other Name <[email protected]>"

Your emails will still go out with the header:

From: Real Name <[email protected]>

In this case, the only command line solution I've found is actually overriding the send-hook itself:

mutt -e "send-hook . \"my_hdr From: Other Name <[email protected]>\""

Open the file again using vi. and then press the insert button to begin editing it.

Actually I think there is a error in the documentation for this particular example. The method that is intended is expectThrows

public static void assertThrows(
public static <T extends Throwable> T expectThrows(

You can do it directly with the HTTPS URL like this:

pip install git+https://github.com/username/repo.git

This also works just appending that line in the requirements.txt in a Django project, for instance.

I assume that you are looking to do something interactive when the textbox changes (i.e. retrieve some data via ajax). I was looking for this same functionality. I know using a global isn't the most robust or elegant solution, but that is what I went with. Here is an example:

var searchValue = $('#Search').val();
$(function () {
    setTimeout(checkSearchChanged, 0.1);
});

function checkSearchChanged() {
    var currentValue = $('#Search').val();
    if ((currentValue) && currentValue != searchValue && currentValue != '') {
        searchValue = $('#Search').val();
        $('#submit').click();
    }
    else {
        setTimeout(checkSearchChanged, 0.1);
    }
}

One key thing to note here is that I am using setTimeout and not setInterval since I don't want to send multiple requests at the same time. This ensures that the timer "stops" when the form is submitted and "starts" when the request is complete. I do this by calling checkSearchChanged when my ajax call completes. Obviously you could expand this to check for minimum length, etc.

In my case, I am using ASP.Net MVC so you can see how to tie this in with MVC Ajax as well in the following post:

http://geekswithblogs.net/DougLampe/archive/2010/12/21/simple-interactive-search-with-jquery-and-asp.net-mvc.aspx

I'd like to give my give my practice.

Use your preferred IDE, take eclipse for for example here:

1. Find an appropriate location within the exception stack
2. Set conditional breakpoint
3. Debug it
4. It will print the corrupted jar before exception

This may be irrelevant. It is for people don't want build the latest git on the host meanwhile they still can get the latest git.

I think most people don't like building the latest git on CentOS because the dependencies will contaminate the host and you have to run lots of commands. Therefore, I have an idea which is building git inside the Docker container and then install the executable via the docker volume mount. After that, you can delete the image and container.

Yes, the downside is you have to install docker. But the least dependencies are introduced to the host and you don't have to install other yum repo.

Here is my repository. https://github.com/wood1986/docker-library/tree/master/git

JSONObject jsonObject =new JSONObject(jsonStr);
JSONArray jsonArray = jsonObject.getJSONArray("data");
for(int i=0;i<jsonArray.length;i++){
    JSONObject json = jsonArray.getJSONObject(i);
    String id = json.getString("id");
    String name=json.getString("name");
    JSONArray ingArray = json.getJSONArray("Ingredients") // here you are going   to get ingredients
    for(int j=0;j<ingArray.length;j++){
        JSONObject ingredObject= ingArray.getJSONObject(j);
        String ingName = ingredObject.getString("name");//so you are going to get   ingredient name
        Log.e("name",ingName); // you will get 
   }
}

You can include the following lines in the file you want to debug:

error_reporting(E_ALL);
ini_set('display_errors', '1');

This overrides the default settings in php.ini, which just make PHP report the errors to the log.

If you use jQuery, u can do it like this:

<form action="example" method="post" id="loginform">
  ...
  <input id="btnin" type="button" value="login"/>
  <input id="btnreg" type="button" value="regist"/>
</form>

And js will be:

$("#btnin").click(function(){
   $("#loginform").attr("action", "user_login");
   $("#loginform").submit();
}
$("#btnreg").click(function(){
   $("#loginform").attr("action", "user_regist");
   $("#loginform").submit();
}

Like this:

>>> s='1\t2\t3\t4\t5'
>>> [x for x in s.split('\t')]
['1', '2', '3', '4', '5']

For a file:

# create test file:
>>> with open('tabs.txt','w') as o:
...    s='\n'.join(['\t'.join(map(str,range(i,i+10))) for i in [0,10,20,30]])
...    print >>o, s

#read that file:
>>> with open('tabs.txt','r') as f:
...    LoL=[x.strip().split('\t') for x in f]
... 
>>> LoL
[['0', '1', '2', '3', '4', '5', '6', '7', '8', '9'], 
 ['10', '11', '12', '13', '14', '15', '16', '17', '18', '19'], 
 ['20', '21', '22', '23', '24', '25', '26', '27', '28', '29'], 
 ['30', '31', '32', '33', '34', '35', '36', '37', '38', '39']]
>>> LoL[2][3]
23

If you want the input transposed:

>>> with open('tabs.txt','r') as f:
...    LoT=zip(*(line.strip().split('\t') for line in f))
... 
>>> LoT[2][3]
'32'

Or (better still) use the csv module in the default distribution...

You need to use the .toFixed() method

It takes as a parameter the number of digits to show after the decimal point.

$(document).ready(function() {
  $('.add').click(function() {
     var value = parseFloat($('#total').text()) + parseFloat($(this).data('amount'))/100
     $('#total').text( value.toFixed(2) );
  });
})

This is by far the best post for exporting to excel from SQL:

http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=49926

To quote from user madhivanan,

Apart from using DTS and Export wizard, we can also use this query to export data from SQL Server2000 to Excel

Create an Excel file named testing having the headers same as that of table columns and use these queries

1 Export data to existing EXCEL file from SQL Server table

insert into OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
    'Excel 8.0;Database=D:\testing.xls;', 
    'SELECT * FROM [SheetName$]') select * from SQLServerTable

2 Export data from Excel to new SQL Server table

select * 
into SQLServerTable FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
    'Excel 8.0;Database=D:\testing.xls;HDR=YES', 
    'SELECT * FROM [Sheet1$]')

3 Export data from Excel to existing SQL Server table (edited)

Insert into SQLServerTable Select * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
    'Excel 8.0;Database=D:\testing.xls;HDR=YES', 
    'SELECT * FROM [SheetName$]')

4 If you dont want to create an EXCEL file in advance and want to export data to it, use

EXEC sp_makewebtask 
    @outputfile = 'd:\testing.xls', 
    @query = 'Select * from Database_name..SQLServerTable', 
    @colheaders =1, 
    @FixedFont=0,@lastupdated=0,@resultstitle='Testing details'

(Now you can find the file with data in tabular format)

5 To export data to new EXCEL file with heading(column names), create the following procedure

create procedure proc_generate_excel_with_columns
(
    @db_name    varchar(100),
    @table_name varchar(100),   
    @file_name  varchar(100)
)
as

--Generate column names as a recordset
declare @columns varchar(8000), @sql varchar(8000), @data_file varchar(100)
select 
    @columns=coalesce(@columns+',','')+column_name+' as '+column_name 
from 
    information_schema.columns
where 
    table_name=@table_name
select @columns=''''''+replace(replace(@columns,' as ',''''' as '),',',',''''')

--Create a dummy file to have actual data
select @data_file=substring(@file_name,1,len(@file_name)-charindex('\',reverse(@file_name)))+'\data_file.xls'

--Generate column names in the passed EXCEL file
set @sql='exec master..xp_cmdshell ''bcp " select * from (select '+@columns+') as t" queryout "'+@file_name+'" -c'''
exec(@sql)

--Generate data in the dummy file
set @sql='exec master..xp_cmdshell ''bcp "select * from '+@db_name+'..'+@table_name+'" queryout "'+@data_file+'" -c'''
exec(@sql)

--Copy dummy file to passed EXCEL file
set @sql= 'exec master..xp_cmdshell ''type '+@data_file+' >> "'+@file_name+'"'''
exec(@sql)

--Delete dummy file 
set @sql= 'exec master..xp_cmdshell ''del '+@data_file+''''
exec(@sql)

After creating the procedure, execute it by supplying database name, table name and file path:

EXEC proc_generate_excel_with_columns 'your dbname', 'your table name','your file path'

Its a whomping 29 pages but that is because others show various other ways as well as people asking questions just like this one on how to do it.

Follow that thread entirely and look at the various questions people have asked and how they are solved. I picked up quite a bit of knowledge just skimming it and have used portions of it to get expected results.

To update single cells

A member also there Peter Larson posts the following: I think one thing is missing here. It is great to be able to Export and Import to Excel files, but how about updating single cells? Or a range of cells?

This is the principle of how you do manage that

update OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
'Excel 8.0;Database=c:\test.xls;hdr=no', 
'SELECT * FROM [Sheet1$b7:b7]') set f1 = -99

You can also add formulas to Excel using this:

update OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
'Excel 8.0;Database=c:\test.xls;hdr=no', 
'SELECT * FROM [Sheet1$b7:b7]') set f1 = '=a7+c7'

Exporting with column names using T-SQL

Member Mladen Prajdic also has a blog entry on how to do this here

References: www.sqlteam.com (btw this is an excellent blog / forum for anyone looking to get more out of SQL Server). For error referencing I used this

Errors that may occur

If you get the following error:

OLE DB provider 'Microsoft.Jet.OLEDB.4.0' cannot be used for distributed queries

Then run this:

sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Ad Hoc Distributed Queries', 1;
GO
RECONFIGURE;
GO

You can get your package name like so:

$ /path/to/adb shell 'pm list packages -f myapp'
package:/data/app/mycompany.myapp-2.apk=mycompany.myapp

Here are the options:

1. Save and close all Internet Explorer windows and then, run Windows Task Manager to end the running processes in background.
2. Go to Control Panel.
3. Click Programs and choose the View installed updates instead.
4. Locate the following Windows Internet Explorer 11 or you can type "Internet Explorer" for a quick search.
5. Choose the Yes option from the following "Uninstall an update".
6. Please wait while Windows Internet Explorer 10 is being restored and reconfigured automatically.
7. Follow the Microsoft Windows wizard to restart your system.

Note: You can do it for as many earlier versions you want, i.e. IE9, IE8 and so on.

"adjustResize"

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

"adjustPan"

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

according to your comment, use following in your activity manifest

<activity android:windowSoftInputMode="adjustResize"> </activity>

Restrict the dimension of the NVARCHAR to 7, supplied to CONVERT to show only "YYYY-MM"

SELECT CONVERT(NVARCHAR(7),PaymentDate,120) [Month], SUM(Amount) [TotalAmount]
FROM Payments
GROUP BY CONVERT(NVARCHAR(7),PaymentDate,120)
ORDER BY [Month]

MS doesn't support LIMIT in t-sql. Most of the times i just get MAX(ID) and then subtract.

select * from ORDERS where ID >(select MAX(ID)-10 from ORDERS)

This will return less than 10 records when ID is not sequential.

1. Open a command prompt as an Administrator.

2. Enter slmgr /upk and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.

3. Enter slmgr /cpky and wait for this to complete. This will remove the product key from the registry if it's still there.

4. Enter slmgr /rearm and wait for this to complete. This is to reset the Windows activation timers so the new users will be prompted to activate Windows when they put in the key.

This should put the system back to a pre-key state.

Hope this helps you out!

If you make this user especial for a specific database, then maybe you do not set it as db_owner in "user mapping" of properties

I always get in here, for this topic. I'll put my code in here so i (or other) can use it next time. (Phew hate to search into my repository code).

Add the permission:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

Add receiver and service:

<receiver android:enabled="true" android:name=".BootUpReceiver"
    android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>
<service android:name="Launcher" />

Create class Launcher:

public class Launcher extends Service {
    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        new AsyncTask<Service, Void, Service>() {

            @Override
            protected Service doInBackground(Service... params) {
                Service service = params[0];
                PackageManager pm = service.getPackageManager();
                try {
                    Intent target = pm.getLaunchIntentForPackage("your.package.id");
                    if (target != null) {
                        service.startActivity(target);
                        synchronized (this) {
                            wait(3000);
                        }
                    } else {
                        throw new ActivityNotFoundException();
                    }
                } catch (ActivityNotFoundException | InterruptedException ignored) {
                }
                return service;
            }

            @Override
            protected void onPostExecute(Service service) {
                service.stopSelf();
            }

        }.execute(this);

        return START_STICKY;
    }
}

Create class BootUpReceiver to do action after android reboot.

For example launch MainActivity:

public class BootUpReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        Intent target = new Intent(context, MainActivity.class);  
        target.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(target);  
    }
}

Just passing the file object to the putobject method worked for me. If you are getting a stream, try writing it to a temp file before passing it on to S3.

amazonS3.putObject(bucketName, id,fileObject);

I am using Aws SDK v1.11.414

I found myself in a similar predicament today while trying to run a command through a Node.js module:

I was using the PowerShell and trying to run:

command -e 'func($a)'

But with the extra symbols, PowerShell was mangling the arguments. To fix, I back-tick escaped double-quote marks:

command -e `"func($a)`"

For example, you have a doc with three fields:

PUT movie/_doc/1
{
  "name":"The Lion King",
  "language":"English",
  "score":"9.3"
}

If you want to return name and score you can use the following command:

GET movie/_doc/1?_source_includes=name,score

If you want to get some fields which match a pattern:

GET movie/_doc/1?_source_includes=*re

Maybe exclude some fields:

GET movie/_doc/1?_source_excludes=score

Yes, you can.

From cplusplus.com:

Because these functions are operator overloading functions, the usual way in which they are called is:

   strm >> variable;

Where strm is the identifier of a istream object and variable is an object of any type supported as right parameter. It is also possible to call a succession of extraction operations as:

   strm >> variable1 >> variable2 >> variable3; //...

which is the same as performing successive extractions from the same object strm.

Just replace strm with cin.

Intent intent = null;
    try {
        getPackageManager().getPackageInfo("com.facebook.katana", 0);
        String url = "https://www.facebook.com/"+idFacebook;
        intent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://facewebmodal/f?href="+url));
    } catch (Exception e) {
        // no Facebook app, revert to browser
        String url = "https://facebook.com/"+idFacebook;
        intent = new Intent(Intent.ACTION_VIEW);
        intent .setData(Uri.parse(url));
    }
    this.startActivity(intent);

Setting session timeout through the deployment descriptor should work - it sets the default session timeout for the web app. Calling session.setMaxInactiveInterval() sets the timeout for the particular session it is called on, and overrides the default. Be aware of the unit difference, too - the deployment descriptor version uses minutes, and session.setMaxInactiveInterval() uses seconds.

So

<session-config>
    <session-timeout>60</session-timeout>
</session-config>

sets the default session timeout to 60 minutes.

And

session.setMaxInactiveInterval(600);

sets the session timeout to 600 seconds - 10 minutes - for the specific session it's called on.

This should work in Tomcat or Glassfish or any other Java web server - it's part of the spec.

Was following one of training with Spring webmvc 4.2.3, while I'm using Spring webmvc 5.2.3 they suggested to create a form

<form:form modelAttribute="aNewAccount" method="get" action="/accountCreated">

that was causing the "disclose" error.

Altered as below to make it work. Looks like method above was the culprit.

<form:form modelAttribute="aNewAccount" action="accountCreated.html">

in fact, exploring further, method="post" in form annotation would work if properly declared:

@RequestMapping(value="/accountCreated", method=RequestMethod.POST)

just write the css attributes in a proper manner i.e:

font-size:35px;

in kotlin :

val sharingIntent = Intent(android.content.Intent.ACTION_SEND)
sharingIntent.type = "text/plain"
val shareBody = "Application Link : https://play.google.com/store/apps/details?id=${App.context.getPackageName()}"
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "App link")
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody)
startActivity(Intent.createChooser(sharingIntent, "Share App Link Via :"))

I have another solution to do it without dynamic query. We can do it with the help of xquery as well.

    SET @Xml = cast(('<A>'+replace('3,4,22,6014',',' ,'</A><A>')+'</A>') AS XML)
    Select @Xml

    SELECT A.value('.', 'varchar(max)') as [Column] FROM @Xml.nodes('A') AS FN(A)

function flatMultidimensionalArray(array &$_arr): array

    $result = [];
    \array_walk_recursive($_arr, static function (&$value, &$key) use (&$result) {

    });

    return $result;
}

is it possible to export without looping through all records

For a range in Excel with a large number of rows you may see some performance improvement if you create an Access.Application object in Excel and then use it to import the Excel data into Access. The code below is in a VBA module in the same Excel document that contains the following test data

Option Explicit

Sub AccImport()
    Dim acc As New Access.Application
    acc.OpenCurrentDatabase "C:\Users\Public\Database1.accdb"
    acc.DoCmd.TransferSpreadsheet _
            TransferType:=acImport, _
            SpreadSheetType:=acSpreadsheetTypeExcel12Xml, _
            TableName:="tblExcelImport", _
            Filename:=Application.ActiveWorkbook.FullName, _
            HasFieldNames:=True, _
            Range:="Folio_Data_original$A1:B10"
    acc.CloseCurrentDatabase
    acc.Quit
    Set acc = Nothing
End Sub

If you want/need to do it without int:

sum(int(c) * (2 ** i) for i, c in enumerate(s[::-1]))

This reverses the string (s[::-1]), gets each character c and its index i (for i, c in enumerate(), multiplies the integer of the character (int(c)) by two to the power of the index (2 ** i) then adds them all together (sum()).

honoring font family, dynamic font I've concocted this abomination:

            return nil
        }
        let mutable = NSMutableAttributedString(attributedString: attributedText)
        if let font = font {
        do {
            var found = false
            mutable.beginEditing()
            mutable.enumerateAttribute(NSAttributedString.Key.font, in: NSMakeRange(0, attributedText.length), options: NSAttributedString.EnumerationOptions(rawValue: 0)) { (value, range, stop) in
                    if let oldFont = value as? UIFont {
                        let newsize = oldFont.pointSize * 15 * Font.scaleHeruistic / 12
                        let newFont = oldFont.withSize(newsize)
                        mutable.addAttribute(NSAttributedString.Key.font, value: newFont, range: range)
                        found = true
                    }
                }
                if !found {
                    // No font was found - do something else?
                }

            mutable.endEditing()
            
//            mutable.addAttribute(.font, value: font, range: NSRange(location: 0, length: mutable.length))
        }
        self.init(attributedString: mutable)
    }

}

alternatively you can use the versions this was derived from and set font on UILabel after setting attributedString

this will clobber the size and boldness encapsulated in the attributestring though

kudos for reading through all the answers up to here. You are a very patient man woman or child.

You can do this all in the File.open block:

Dir.chdir 'C:/Users/name/Music'
music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
puts 'what would you like to call the playlist?'
playlist_name = gets.chomp + '.m3u'

File.open playlist_name, 'w' do |f|
  music.each do |z|
    f.puts z
  end
end

this function worked for me

<?php

function everything_in_tags($string, $tagname)
{
    $pattern = "#<\s*?$tagname\b[^>]*>(.*?)</$tagname\b[^>]*>#s";
    preg_match($pattern, $string, $matches);
    return $matches[1];
}

?>

(C++17 and above):

can use std::search also

This is also useful for searching sequence of elements.

#include <algorithm>
#include <iostream>
#include <vector>

template <typename Container>
bool search_vector(const Container& vec, const Container& searchvec)
{
    return std::search(vec.begin(), vec.end(), searchvec.begin(), searchvec.end()) != vec.end();
}

int main()
{
     std::vector<int> v = {2,4,6,8};

     //THIS WORKS. SEARCHING ONLY ONE ELEMENT.
     std::vector<int> searchVector1 = {2};
     if(search_vector(v,searchVector1))
         std::cout<<"searchVector1 found"<<std::endl;
     else
         std::cout<<"searchVector1 not found"<<std::endl;

     //THIS WORKS, AS THE ELEMENTS ARE SEQUENTIAL.
     std::vector<int> searchVector2 = {6,8};
     if(search_vector(v,searchVector2))
         std::cout<<"searchVector2 found"<<std::endl;
     else
         std::cout<<"searchVector2 not found"<<std::endl;

     //THIS WILL NOT WORK, AS THE ELEMENTS ARE NOT SEQUENTIAL.
     std::vector<int> searchVector3 = {8,6};
     if(search_vector(v,searchVector3))
         std::cout<<"searchVector3 found"<<std::endl;
     else
         std::cout<<"searchVector3 not found"<<std::endl;
}

Also there is flexibility of passing some search algorithms. Refer here.

set the height to 200

Set the Font to a large variant (150+ px). As already mentioned, control the width using columns, and use a layout manager (or constraint) that will respect the preferred width & height.

public class BigTextField {

    public static void main(String[] args) {

                // the GUI as seen by the user (without frame)
                JPanel gui = new JPanel(new FlowLayout(5));
                gui.setBorder(new EmptyBorder(2, 3, 2, 3));

                // Create big text fields & add them to the GUI
                String s = "Hello!";
                JTextField tf1 = new JTextField(s, 1);
                Font bigFont = tf1.getFont().deriveFont(Font.PLAIN, 150f);
                tf1.setFont(bigFont);

The table normally contains multiple rows. Use a loop and use row.Field<string>(0) to access the value of each row.

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>("File");
}

You can also access it via index:

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>(0);
}

If you expect only one row, you can also use the indexer of DataRowCollection:

string file = dt.Rows[0].Field<string>(0); 

Since this fails if the table is empty, use dt.Rows.Count to check if there is a row:

if(dt.Rows.Count > 0)
    file = dt.Rows[0].Field<string>(0);

Combining the answers above, you can implement something that works like the gem colorize without needing another dependency.

class String
  # colorization
  def colorize(color_code)
    "\e[#{color_code}m#{self}\e[0m"
  end

  def red
    colorize(31)
  end

  def green
    colorize(32)
  end

  def yellow
    colorize(33)
  end

  def blue
    colorize(34)
  end

  def pink
    colorize(35)
  end

  def light_blue
    colorize(36)
  end
end

To get a footer that sticks to the bottom of your viewport, give it a fixed position like this:

footer {
    position: fixed;
    height: 100px;
    bottom: 0;
    width: 100%;
}

Bootstrap includes this CSS in the Navbar > Placement section with the class fixed-bottom. Just add this class to your footer element:

<footer class="fixed-bottom">

Answer if you only want to use for each loop ..

for (WebElement s : options) {
    int i = options.indexOf(s);
    System.out.println(options.get(i).getText());
}

WORKING:

$("#ContentPlaceHolder1_txtNombre").keyup(function () {
    var txt = $(this).val();
        $('.column').each(function () {
            $(this).show();
            if ($(this).text().toUpperCase().indexOf(txt.toUpperCase()) == -1) {
                $(this).hide();
            }
        });
    //}
});

If you want the last 5 rows, ordered in ascending order, you need a subquery:

SELECT *
FROM
    ( SELECT id, name, form_id, DATE(updated_at) AS updated_date, updated_at
      FROM wp_frm_items
      WHERE user_id = 11 
        AND form_id=9
      ORDER BY updated_at DESC
      LIMIT 5
    ) AS tmp
ORDER BY updated_at

After reading the question for 10th time, this may be (just maybe) what you want. Order by Date descending and then order by time (on same date) ascending:

SELECT id, name, form_id, DATE(updated_at) AS updated_date
FROM wp_frm_items
WHERE user_id = 11 
  AND form_id=9
ORDER BY DATE(updated_at) DESC
       , updated_at ASC

In my case I had special instruction into nginx configuration file:

location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {
            try_files $uri =404;
    }

All clients have received '404' because nginx nothing known about Flask.

I hope it help someone.

With Groovy, you don't need the includes, and can just do:

String oldDate = '04-DEC-2012'
Date date = Date.parse( 'dd-MMM-yyyy', oldDate )
String newDate = date.format( 'M-d-yyyy' )

println newDate

To print:

12-4-2012

Errr, it's a bit messy in the view. But I think I've gotten it to work with group (http://mongoid.org/docs/querying/)

Controller

@event_attendees = Activity.only(:user_id).where(:action => 'Attend').order_by(:created_at.desc).group

View

<% @event_attendees.each do |event_attendee| %>    
  <%= event_attendee['group'].first.user.first_name %>
<% end %>

Looking for EventHandling, ActionListener?

or code?

JButton b = new JButton("Clear");
b.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent e){
        textfield.setText("");
        //textfield.setText(null); //or use this
    }
});

I had the same issue and found out that I had another key file in ~/.ssh for a different GitHub repository. Somehow it was used instead of the new one.

from zipfile import ZipFile
ZipFile("YOURZIP.zip").extractall("YOUR_DESTINATION_DIRECTORY")

The directory where you will extract your files doesn't need to exist before, you name it at this moment

YOURZIP.zip is the name of the zip if your project is in the same directory. If not, use the PATH i.e : C://....//YOURZIP.zip

Think to escape the / by an other / in the PATH If you have a permission denied try to launch your ide (i.e: Anaconda) as administrator

YOUR_DESTINATION_DIRECTORY will be created in the same directory than your project

insert into OPT       (email,        campaign_id) 
select 'mom@coxnet' as email, 100 as campaign_id from dual MINUS
select                 email,        campaign_id from OPT;

If there is already a record with [email protected]/100 in OPT, the MINUS will subtract this record from the select 'mom@coxnet' as email, 100 as campaign_id from dual record and nothing will be inserted. On the other hand, if there is no such record, the MINUS does not subract anything and the values mom@coxnet/100 will be inserted.

As p.marino has already pointed out, merge is probably the better (and more correct) solution for your problem as it is specifically designed to solve your task.

OK I found it.

=LARGE($E$4:$E$9;A12)

=large(array, k)

Array Required. The array or range of data for which you want to determine the k-th largest value.

K Required. The position (from the largest) in the array or cell range of data to return.

when we call ASCII as 7 bit code, the left most bit is used as sign bit so with 7 bits we can write up to 127. that means from -126 to 127 because Max imam value of ASCII is 0 to 255. this can be only satisfied with the argument of 7 bit if last bit is considered as sign bit

I wrote a little jQuery extension for this:

$.fn.nl2brText = function (sText) {
    var bReturnValue = 'undefined' == typeof sText;
    if(bReturnValue) {
        sText = $('<pre>').html(this.html().replace(/<br[^>]*>/i, '\n')).text();
    }
    var aElms = [];
    sText.split(/\r\n|\r|\n/).forEach(function(sSubstring) {
        if(aElms.length) {
            aElms.push(document.createElement('br'));
        }
        aElms.push(document.createTextNode(sSubstring));
    });
    var $aElms = $(aElms);
    if(bReturnValue) {
        return $aElms;
    }
    return this.empty().append($aElms);
};

Follow These Steps and it Will Work For You :

1. run msfconsole
2. type db_console
3. some information will be shown to you chose the information who tell you to make: db_connect user:pass@host:port.../database sorry I don't remember it but it's like this one then replace the user and the password and the host and the database with the information included in the database.yml in the emplacement: /usr/share/metasploit-framework/config
4. you will see. rebuilding the model cache in the background.
5. Type apt-get update && apt-get upgrade after the update restart the terminal and lunch msfconsole and it works you can check that by typing in msfconsole: msf>db_status you will see that it's connected.

There are well maintained libraries that already do this. One example on the npm registry is merge-deep

The OP's questions about canonical form and how it can improve performance of the equals method can both be answered by extending the example provided in Effective Java.

Consider the following class:

public final class CaseInsensitiveString {

  private final String s;

  public CaseInsensitiveString(String s) {
    this.s = Objects.requireNonNull(s);
  }

  @Override 
  public boolean equals(Object o) {
    return o instanceof CaseInsensitiveString && ((CaseInsensitiveString) o).s.equalsIgnoreCase(s);
  }
}

The equals method in this example has added cost by using String's equalsIgnoreCase method. As mentioned in the text

you may want to store a canonical form of the field so the equals method can do a cheap exact comparison on canonical forms rather than a more costly nonstandard comparison.

What does Joshua Bloch mean when he says canonical form? Well, I think Dónal's concise answer is very appropriate. We can store the underlying String field in the CaseInsensitiveString example in a standard way, perhaps the uppercase form of the String. Now, you can reference this canonical form of the CaseInsensitiveString, its uppercase variant, and perform cheap evaluations in your equals and hashcode methods.

@Synxmax's answer is correct when using a Service and the MediaPlayer class, however you also need to declare the Service in the Manifest for this to work, like so:

<service
    android:enabled="true"
    android:name="com.package.name.BackgroundSoundService" />

For what it's worth, I had the same problem but it wasn't because of an extra semicolon, it was because I'd forgotten a semicolon on the previous statement.

My situation was something like

mynamespace::MyObject otherObject

for (const auto& element: otherObject.myVector) {
  // execute arbitrary code on element
  //...
  //...
} 

From this code, my compiler kept telling me:

error: expected unqualified-id before for (const auto& element: otherObject.myVector) { etc... which I'd taken to mean I'd writtten the for loop wrong. Nope! I'd simply forgotten a ; after declaring otherObject.

Actually in some devices the external sdcard default name is showing as extSdCard and for other it is sdcard1.

This code snippet helps to find out that exact path and helps to retrieve you the path of external device.

String sdpath,sd1path,usbdiskpath,sd0path;    
        if(new File("/storage/extSdCard/").exists())
            {
               sdpath="/storage/extSdCard/";
               Log.i("Sd Cardext Path",sdpath);
            }
        if(new File("/storage/sdcard1/").exists())
         {
              sd1path="/storage/sdcard1/";
              Log.i("Sd Card1 Path",sd1path);
         }
        if(new File("/storage/usbcard1/").exists())
         {
              usbdiskpath="/storage/usbcard1/";
              Log.i("USB Path",usbdiskpath);
         }
        if(new File("/storage/sdcard0/").exists())
         {
              sd0path="/storage/sdcard0/";
              Log.i("Sd Card0 Path",sd0path);
         }

Involve following steps to resolve the issue:

1) Install the CLI and env preset

$ npm install --save-dev babel-cli babel-preset-env

2) Create a .babelrc file

{
  "presets": ["env"]
}

3) configure npm start in package.json

"scripts": {
    "start": "babel-node ./server/app.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  }

4) then start app

$ npm start

As I understand your question, you want to write some function y = interpolate(x_values, y_values, x), which will give you the y value at some x? The basic idea then follows these steps:

1. Find the indices of the values in x_values which define an interval containing x. For instance, for x=3 with your example lists, the containing interval would be [x1,x2]=[2.5,3.4], and the indices would be i1=1, i2=2
2. Calculate the slope on this interval by (y_values[i2]-y_values[i1])/(x_values[i2]-x_values[i1]) (ie dy/dx).
3. The value at x is now the value at x1 plus the slope multiplied by the distance from x1.

You will additionally need to decide what happens if x is outside the interval of x_values, either it's an error, or you could interpolate "backwards", assuming the slope is the same as the first/last interval.

Did this help, or did you need more specific advice?

It depends on either the configuration or programmatic change.
Therefore the most reliable way to check the current value is at runtime via code.

See the HttpSessionState.Timeout property; default value is 20 minutes.

You can access this propery in ASP.NET via HttpContext:

this.HttpContext.Session.Timeout // ASP.NET MVC controller
Page.Session.Timeout // ASP.NET Web Forms code-behind
HttpContext.Current.Session.Timeout // Elsewhere

It should be on Project -> app folder

From Apache Commons library:

import org.apache.commons.lang3.StringUtils

Another similar question and answer here

Assuming a Css class of "image" :

input.image { 
  background: url(/i/bg.png) no-repeat top left; 
  width: /* img-width */; 
  height: /* img-height */ 
}

If you don't know what the image width and height are, you can set this dynamically with javascript.

Why can't you use it in MVC?

Rather than using the body load method use jQuery and wait for the the document onready function to complete.

We encountered this issue on a Tomcat running from a jre directory that was (almost fully) removed after an automatic jre update, so that the running jre could no longer find jre.../lib/security/cacerts because it no longer existed.

Restarting Tomcat (after changing the configuration to run from the different jre location) fixed the problem.

It worked for me:

     window.location = $('#myanchor').attr('href');

I'll add another case where I was getting the same error but just being a dummy. I had added [routerLinkActiveOptions]="{exact: true}" without yet adding routerLinkActive="active".

My incorrect code was

<a class="nav-link active" routerLink="/dashboard" [routerLinkActiveOptions]="{exact: true}">
  Home
</a>

when it should have been

<a class="nav-link active" routerLink="/dashboard" routerLinkActive="active" [routerLinkActiveOptions]="{exact: true}">
  Home
</a>

Without having routerLinkActive, you can't have routerLinkActiveOptions.

I would use an algorithm, brute force could be as follows:

First time through loop: Generate a random number between 100,000 through 999,999 and call that x1

Second time through the loop Generate a random number between 100,000 and x1 call this xt2, then generate a random number between x1 and 999,999 call this xt3, then randomly choose x2 or x3, call this x2

Nth time through the loop Generate random number between 100,000 and x1, x1 and x2, and x2 through 999,999 and so forth...

watch out for endpoints, also watch out for x1

I removed the float from the second div to make it work.

convert number string to array, split by decimal point. Then, if the array has only one value, that means no decimal in string.

if(!number.split(".")[1]){
    //do stuff
}

This way you can also know what the integer and decimal actually are. a more advanced example would be.

number_to_array = string.split(".");
inte = number_to_array[0];
dece = number_to_array[1]; 

if(!dece){
    //do stuff
}

my two cents for VS 2017:

I can confirm it works in stdafx.h both in these styles:

a)

#pragma once
#define _CRT_SECURE_NO_WARNINGS 1 
#define _WINSOCK_DEPRECATED_NO_WARNINGS 1 

b)

#define _CRT_SECURE_NO_WARNINGS 1 
#define _WINSOCK_DEPRECATED_NO_WARNINGS 1 
#pragma once

(I have added another define for MSDN network calls..) Of course I do prefer a).

I can confirm that: #define _CRT_SECURE_NO_WARNINGS (without a value) DOES NOT WORK.

PS the real point is to put these defines BEFORE declarations of functions, i.e. before *.h

String str = "129018";
String str2 = String.format("%10s", str).replace(' ', '0');

While not exactly renaming, dplyr::select_all() can be used to reformat column names. This example replaces spaces and periods with an underscore and converts everything to lower case:

Save the username and password hashes in array in a php file instead of db.

When you need to authenticate the user, compute hashes of his credentials and then compare them to hashes in array.

If you use safe hash function (see hash function and hash algos in PHP documentation), it should be pretty safe (you may consider using salted hash) and also add some protections to the form itself.

Extending @endian 's answer, you could use a thread and call a method to update the TextView. Below is some code I made up on the spot.

    super.onCreate(savedInstanceState);
    setContentView(R.layout.deskclock);

    tvTime = (TextView) findViewById(R.id.tvTime);
    tvDate = (TextView) findViewById(R.id.tvDate);

    Thread t = new Thread() {

        @Override
        public void run() {
            try {

Use extension method

 public static object ToSafeDbDateDBnull(this object objectstring)
    {
        try

            if ((DateTime)objectstring >= SqlDateTime.MinValue)
            {
                return objectstring;
            }
            else
            {
                return DBNull.Value;
            }
        }
        catch (Exception)
        {

            return DBNull.Value;
        }

    }

DateTime objdte = new DateTime(1000, 1, 1);
dte.ToSafeDbDateDBnull();

I think amazon definition is straight and simple to understand.

"Continuous delivery is a software development methodology where the release process is automated. Every software change is automatically built, tested, and deployed to production. Before the final push to production, a person, an automated test, or a business rule decides when the final push should occur. Although every successful software change can be immediately released to production with continuous delivery, not all changes need to be released right away.

Continuous integration is a software development practice where members of a team use a version control system and integrate their work frequently to the same location, such as a master branch. Each change is built and verified by tests and other verifications in order to detect any integration errors as quickly as possible. Continuous integration is focused on automatically building and testing code, as compared to continuous delivery, which automates the entire software release process up to production."

I know it's old news but to add my two cents. By default I use the commands LIKE[cd] rather than just [c]. The [d] compares letters with accent symbols. This works especially well in my Warcraft App where people spell their name "Vòódòó" making it nearly impossible to search for their name in a tableview. The [d] strips their accent symbols during the predicate. So a predicate of @"name LIKE[CD] %@", object.name where object.name == @"voodoo" will return the object containing the name Vòódòó.

From the Apple documentation: like[cd] means “case- and diacritic-insensitive like.”) For a complete description of the string syntax and a list of all the operators available, see Predicate Format String Syntax.

C# Thread.Abort is NOT guaranteed to abort the thread instantaneously. It will probably work when a thread calls Abort on itself but not when a thread calls on another.

Please refer to the documentation: http://msdn.microsoft.com/en-us/library/ty8d3wta.aspx

I have faced this problem writing tools that interact with hardware - you want immediate stop but it is not guaranteed. I typically use some flags or other such logic to prevent execution of parts of code running on a thread (and which I do not want to be executed on abort - tricky).

I am trying to push value in an array state and set value like this and define state array and push value by map function.

 this.state = {
        createJob: [],
        totalAmount:Number=0
    }


 your_API_JSON_Array.map((_) => {
                this.setState({totalAmount:this.state.totalAmount += _.your_API_JSON.price})
                this.state.createJob.push({ id: _._id, price: _.your_API_JSON.price })
                return this.setState({createJob: this.state.createJob})
            })

If you just want to apply a function to each element and put the results in an output array, you can use arrayfun.

As others have pointed out, for most operations, it's best to avoid loops in MATLAB and vectorise your code instead.

There are too many points in the process you describe where errors can occur, so I won't try to guess what you're doing wrong, but I think I know what's happening under the hood.

EF BF BD is the UTF-8 encoded form of U+FFFD, the standard replacement character that's inserted by decoders when they encounter malformed input. It sounds like your text is being saved as ISO-8859-1, then read as if it were UTF-8, then saved as UTF-8, then converted to the Properties format using native2ascii using the platform default encoding (e.g., windows-1252).

ü              => 0xFC                // save as ISO-8859-1
0xFC           => U+FFFD              // read as UTF-8
U+FFFD         => 0xEF 0xBF 0xBD      // save as UTF-8
0xEF 0xBF 0xBD => \u00EF\u00BF\u00BD  // native2ascii

I suggest you leave the "file.encoding" property alone. Like "file.separator" and "line.separator", it's not nearly as useful as you would expect it to be. Instead, get into the habit of always specifying an encoding when reading and writing text files.

From 0.2.13 to 0.3.0 Just download new gradle 1.8 from http://www.gradle.org/downloads Reimport project and choose new gradle to use.

in build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.1'
    }
}

not sure it really need, but i use invalidate caches and restart before reimport project

I decided not to touch headers and make a redirect on the server side instead and it woks like a charm.

The example below is for the current version of Angular (currently 9) and probably any other framework using webpacks DevServer. But I think the same principle will work on other backends.

So I use the following configuration in the file proxy.conf.json:

{
  "/api": {
    "target": "http://localhost:3000",
    "pathRewrite": {"^/api" : ""},
   "secure": false
 }
}

In case of Angular I serve with that configuration:

$ ng serve -o --proxy-config=proxy.conf.json

I prefer to use the proxy in the serve command, but you may also put this configuration to angular.json like this:

"architect": {
  "serve": {
    "builder": "@angular-devkit/build-angular:dev-server",
    "options": {
      "browserTarget": "your-application-name:build",
      "proxyConfig": "src/proxy.conf.json"
    },

Have a max int and set it to the first value in the array. Then in a for loop iterate through the whole array and see if the max int is larger than the int at the current index.

int max = array.get(0);

for (int i = 1; i < array.length; i++) {
    if (array.get(i) > max) {
      max = array.get(i);
    }
}

You need a delimiter for your pattern. It should be added at the start and end of the pattern like so:

$pattern = "/My name is '(.*)' and im fine/";  // With / as a delimeter 

The answer from @KM is good as far as it goes but fails to fully follow up on one of his early bits of advice;

..., ignore compact code, ignore worrying about repeating code, ...

If you are looking to achieve the best performance then you should write a bespoke query for each possible combination of optional criteria. This might sound extreme, and if you have a lot of optional criteria then it might be, but performance is often a trade-off between effort and results. In practice, there might be a common set of parameter combinations that can be targeted with bespoke queries, then a generic query (as per the other answers) for all other combinations.

CREATE PROCEDURE spDoSearch
    @FirstName varchar(25) = null,
    @LastName varchar(25) = null,
    @Title varchar(25) = null
AS
BEGIN

    IF (@FirstName IS NOT NULL AND @LastName IS NULL AND @Title IS NULL)
        -- Search by first name only
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            FirstName = @FirstName

    ELSE IF (@FirstName IS NULL AND @LastName IS NOT NULL AND @Title IS NULL)
        -- Search by last name only
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            LastName = @LastName

    ELSE IF (@FirstName IS NULL AND @LastName IS NULL AND @Title IS NOT NULL)
        -- Search by title only
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            Title = @Title

    ELSE IF (@FirstName IS NOT NULL AND @LastName IS NOT NULL AND @Title IS NULL)
        -- Search by first and last name
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
            FirstName = @FirstName
            AND LastName = @LastName

    ELSE
        -- Search by any other combination
        SELECT ID, FirstName, LastName, Title
        FROM tblUsers
        WHERE
                (@FirstName IS NULL OR (FirstName = @FirstName))
            AND (@LastName  IS NULL OR (LastName  = @LastName ))
            AND (@Title     IS NULL OR (Title     = @Title    ))

END

The advantage of this approach is that in the common cases handled by bespoke queries the query is as efficient as it can be - there's no impact by the unsupplied criteria. Also, indexes and other performance enhancements can be targeted at specific bespoke queries rather than trying to satisfy all possible situations.

What you call "Two-Way SSL" is usually called TLS/SSL with client certificate authentication.

In a "normal" TLS connection to example.com only the client verifies that it is indeed communicating with the server for example.com. The server doesn't know who the client is. If the server wants to authenticate the client the usual thing is to use passwords, so a client needs to send a user name and password to the server, but this happens inside the TLS connection as part of an inner protocol (e.g. HTTP) it's not part of the TLS protocol itself. The disadvantage is that you need a separate password for every site because you send the password to the server. So if you use the same password on for example PayPal and MyPonyForum then every time you log into MyPonyForum you send this password to the server of MyPonyForum so the operator of this server could intercept it and try it on PayPal and can issue payments in your name.

Client certificate authentication offers another way to authenticate the client in a TLS connection. In contrast to password login, client certificate authentication is specified as part of the TLS protocol. It works analogous to the way the client authenticates the server: The client generates a public private key pair and submits the public key to a trusted CA for signing. The CA returns a client certificate that can be used to authenticate the client. The client can now use the same certificate to authenticate to different servers (i.e. you could use the same certificate for PayPal and MyPonyForum without risking that it can be abused). The way it works is that after the server has sent its certificate it asks the client to provide a certificate too. Then some public key magic happens (if you want to know the details read RFC 5246) and now the client knows it communicates with the right server, the server knows it communicates with the right client and both have some common key material to encrypt and verify the connection.

Definitely Docker for the win!

As you may know Vagrant is for virtual machine management whereas Docker is for software containers management. If you are not aware of the difference, here is: A software container can share the same machine and kernel with other software containers. Using containers you save money because you don't waste resources on multiple operating systems (kernels), you can pack more software per server keeping a good degree of isolation.

Of course is a new discipline to care with its own pitfals and challenges.

Go for Docker Swarm if your requirements cross the single machine resources limit.

I'm assuming c++ here. If you're using c#, the answer is probably the same, but the syntax will be a bit different. The enum is a set of int values. It's not an object, so you shouldn't be setting it to null. Setting something to null means you are pointing a pointer to an object to address zero. You can't really do that with an int. What you want to do with an int is to set it to a value you wouldn't normally have it at so that you can tel if it's a good value or not. So, set your colour to -1

Color color = -1;

Or, you can start your enum at 1 and set it to zero. If you set the colour to zero as it is right now, you will be setting it to "red" because red is zero in your enum.

So,

enum Color {
red =1
blue,
green
}
//red is 1, blue is 2, green is 3
Color mycolour = 0;

Xoom has the word Xoom in the user-agent: Mozilla/5.0 (Linux; U; Android 3.0.1; en-us; Xoom Build/HRI66) AppleWebKit/534.13 (KHTML, like Gecko) Version/4.0 Safari/534.13

Galaxy Tab has "Mobile" in the user-agent: Mozilla/5.0 (Linux; U; Android 2.2; en-us; SCH-I800 Build/FROYO) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1

So, it's easy to detect the Xoom, hard to detect if a specific Android version is mobile or not.

You're declaring (some of) your event handlers incorrectly:

$('.menuOption').click(function( event ){ // <---- "event" parameter here

    event.preventDefault();
    var categories = $(this).attr('rel');
    $('.pages').hide();
    $(categories).fadeIn();


});

You need "event" to be a parameter to the handlers. WebKit follows IE's old behavior of using a global symbol for "event", but Firefox doesn't. When you're using jQuery, that library normalizes the behavior and ensures that your event handlers are passed the event parameter.

edit — to clarify: you have to provide some parameter name; using event makes it clear what you intend, but you can call it e or cupcake or anything else.

Note also that the reason you probably should use the parameter passed in from jQuery instead of the "native" one (in Chrome and IE and Safari) is that that one (the parameter) is a jQuery wrapper around the native event object. The wrapper is what normalizes the event behavior across browsers. If you use the global version, you don't get that.

The SIMPLEST answer is to put "data" into a pair of square brackets (i.e. [data]):

     $.getJSON("json/products.json").done(function (data) {

         var allProducts = [data].map(function (item) {
             return new getData(item);
         });

     });

Here, [data] is an array, and the ".map" method can be used on it. It works for me!

While technically correct, the other answers would benefit from an explanation of Angular's URL-to-route matching. I don't think you can fully (pardon the pun) understand what pathMatch: full does if you don't know how the router works in the first place.

Let's first define a few basic things. We'll use this URL as an example: /users/james/articles?from=134#section.

1. It may be obvious but let's first point out that query parameters (?from=134) and fragments (#section) do not play any role in path matching. Only the base url (/users/james/articles) matters.

2. Angular splits URLs into segments. The segments of /users/james/articles are, of course, users, james and articles.

3. The router configuration is a tree structure with a single root node. Each Route object is a node, which may have children nodes, which may in turn have other children or be leaf nodes.

The goal of the router is to find a router configuration branch, starting at the root node, which would match exactly all (!!!) segments of the URL. This is crucial! If Angular does not find a route configuration branch which could match the whole URL - no more and no less - it will not render anything.

E.g. if your target URL is /a/b/c but the router is only able to match either /a/b or /a/b/c/d, then there is no match and the application will not render anything.

Finally, routes with redirectTo behave slightly differently than regular routes, and it seems to me that they would be the only place where anyone would really ever want to use pathMatch: full. But we will get to this later.

Default (prefix) path matching

The reasoning behind the name prefix is that such a route configuration will check if the configured path is a prefix of the remaining URL segments. However, the router is only able to match full segments, which makes this naming slightly confusing.

Anyway, let's say this is our root-level router configuration:

const routes: Routes = [
  {
    path: 'products',
    children: [
      {
        path: ':productID',
        component: ProductComponent,
      },
    ],
  },
  {
    path: ':other',
    children: [
      {
        path: 'tricks',
        component: TricksComponent,
      },
    ],
  },
  {
    path: 'user',
    component: UsersonComponent,
  },
  {
    path: 'users',
    children: [
      {
        path: 'permissions',
        component: UsersPermissionsComponent,
      },
      {
        path: ':userID',
        children: [
          {
            path: 'comments',
            component: UserCommentsComponent,
          },
          {
            path: 'articles',
            component: UserArticlesComponent,
          },
        ],
      },
    ],
  },
];

Note that every single Route object here uses the default matching strategy, which is prefix. This strategy means that the router iterates over the whole configuration tree and tries to match it against the target URL segment by segment until the URL is fully matched. Here's how it would be done for this example:

1. Iterate over the root array looking for a an exact match for the first URL segment - users.
2. 'products' !== 'users', so skip that branch. Note that we are using an equality check rather than a .startsWith() or .includes() - only full segment matches count!
3. :other matches any value, so it's a match. However, the target URL is not yet fully matched (we still need to match james and articles), thus the router looks for children.

• The only child of :other is tricks, which is !== 'james', hence not a match.

4. Angular then retraces back to the root array and continues from there.
5. 'user' !== 'users, skip branch.
6. 'users' === 'users - the segment matches. However, this is not a full match yet, thus we need to look for children (same as in step 3).

• 'permissions' !== 'james', skip it.
• :userID matches anything, thus we have a match for the james segment. However this is still not a full match, thus we need to look for a child which would match articles.
  1. We can see that :userID has a child route articles, which gives us a full match! Thus the application renders UserArticlesComponent.

Full URL (full) matching

Example 1

Imagine now that the users route configuration object looked like this:

{
  path: 'users',
  component: UsersComponent,
  pathMatch: 'full',
  children: [
    {
      path: 'permissions',
      component: UsersPermissionsComponent,
    },
    {
      path: ':userID',
      component: UserComponent,
      children: [
        {
          path: 'comments',
          component: UserCommentsComponent,
        },
        {
          path: 'articles',
          component: UserArticlesComponent,
        },
      ],
    },
  ],
}

Note the usage of pathMatch: full. If this were the case, steps 1-5 would be the same, however step 6 would be different:

6. 'users' !== 'users/james/articles - the segment does not match because the path configuration users with pathMatch: full does not match the full URL, which is users/james/articles.
7. Since there is no match, we are skipping this branch.
8. At this point we reached the end of the router configuration without having found a match. The application renders nothing.

Example 2

What if we had this instead:

{
  path: 'users/:userID',
  component: UsersComponent,
  pathMatch: 'full',
  children: [
    {
      path: 'comments',
      component: UserCommentsComponent,
    },
    {
      path: 'articles',
      component: UserArticlesComponent,
    },
  ],
}

users/:userID with pathMatch: full matches only users/james thus it's a no-match once again, and the application renders nothing.

Example 3

Let's consider this:

{
  path: 'users',
  children: [
    {
      path: 'permissions',
      component: UsersPermissionsComponent,
    },
    {
      path: ':userID',
      component: UserComponent,
      pathMatch: 'full',
      children: [
        {
          path: 'comments',
          component: UserCommentsComponent,
        },
        {
          path: 'articles',
          component: UserArticlesComponent,
        },
      ],
    },
  ],
}

In this case:

6. 'users' === 'users - the segment matches, but james/articles still remains unmatched. Let's look for children.

• 'permissions' !== 'james' - skip.
• :userID' can only match a single segment, which would be james. However, it's a pathMatch: full route, and it must match james/articles (the whole remaining URL). It's not able to do that and thus it's not a match (so we skip this branch)!

7. Again, we failed to find any match for the URL and the application renders nothing.

As you may have noticed, a pathMatch: full configuration is basically saying this:

Ignore my children and only match me. If I am not able to match all of the remaining URL segments myself, then move on.

Redirects

Any Route which has defined a redirectTo will be matched against the target URL according to the same principles. The only difference here is that the redirect is applied as soon as a segment matches. This means that if a redirecting route is using the default prefix strategy, a partial match is enough to cause a redirect. Here's a good example:

const routes: Routes = [
  {
    path: 'not-found',
    component: NotFoundComponent,
  },
  {
    path: 'users',
    redirectTo: 'not-found',
  },
  {
    path: 'users/:userID',
    children: [
      {
        path: 'comments',
        component: UserCommentsComponent,
      },
      {
        path: 'articles',
        component: UserArticlesComponent,
      },
    ],
  },
];

For our initial URL (/users/james/articles), here's what would happen:

1. 'not-found' !== 'users' - skip it.
2. 'users' === 'users' - we have a match.
3. This match has a redirectTo: 'not-found', which is applied immediately.
4. The target URL changes to not-found.
5. The router begins matching again and finds a match for not-found right away. The application renders NotFoundComponent.

Now consider what would happen if the users route also had pathMatch: full:

const routes: Routes = [
  {
    path: 'not-found',
    component: NotFoundComponent,
  },
  {
    path: 'users',
    pathMatch: 'full',
    redirectTo: 'not-found',
  },
  {
    path: 'users/:userID',
    children: [
      {
        path: 'comments',
        component: UserCommentsComponent,
      },
      {
        path: 'articles',
        component: UserArticlesComponent,
      },
    ],
  },
];

1. 'not-found' !== 'users' - skip it.
2. users would match the first segment of the URL, but the route configuration requires a full match, thus skip it.
3. 'users/:userID' matches users/james. articles is still not matched but this route has children.

• We find a match for articles in the children. The whole URL is now matched and the application renders UserArticlesComponent.

Empty path (path: '')

The empty path is a bit of a special case because it can match any segment without "consuming" it (so it's children would have to match that segment again). Consider this example:

const routes: Routes = [
  {
    path: '',
    children: [
      {
        path: 'users',
        component: BadUsersComponent,
      }
    ]
  },
  {
    path: 'users',
    component: GoodUsersComponent,
  },
];

Let's say we are trying to access /users:

• path: '' will always match, thus the route matches. However, the whole URL has not been matched - we still need to match users!
• We can see that there is a child users, which matches the remaining (and only!) segment and we have a full match. The application renders BadUsersComponent.

Now back to the original question

The OP used this router configuration:

const routes: Routes = [
  {
    path: 'welcome',
    component: WelcomeComponent,
  },
  {
    path: '',
    redirectTo: 'welcome',
    pathMatch: 'full',
  },
  {
    path: '**',
    redirectTo: 'welcome',
    pathMatch: 'full',
  },
];

If we are navigating to the root URL (/), here's how the router would resolve that:

1. welcome does not match an empty segment, so skip it.
2. path: '' matches the empty segment. It has a pathMatch: 'full', which is also satisfied as we have matched the whole URL (it had a single empty segment).
3. A redirect to welcome happens and the application renders WelcomeComponent.

What if there was no pathMatch: 'full'?

Actually, one would expect the whole thing to behave exactly the same. However, Angular explicitly prevents such a configuration ({ path: '', redirectTo: 'welcome' }) because if you put this Route above welcome, it would theoretically create an endless loop of redirects. So Angular just throws an error, which is why the application would not work at all! (https://angular.io/api/router/Route#pathMatch)

Actually, this does not make too much sense to me because Angular also has implemented a protection against such endless redirects - it only runs a single redirect per routing level! This would stop all further redirects (as you'll see in the example below).

What about path: '**'?

path: '**' will match absolutely anything (af/frewf/321532152/fsa is a match) with or without a pathMatch: 'full'.

Also, since it matches everything, the root path is also included, which makes { path: '', redirectTo: 'welcome' } completely redundant in this setup.

Funnily enough, it is perfectly fine to have this configuration:

const routes: Routes = [
  {
    path: '**',
    redirectTo: 'welcome'
  },
  {
    path: 'welcome',
    component: WelcomeComponent,
  },
];

If we navigate to /welcome, path: '**' will be a match and a redirect to welcome will happen. Theoretically this should kick off an endless loop of redirects but Angular stops that immediately (because of the protection I mentioned earlier) and the whole thing works just fine.

Pass the array to a method that sorts it with Arrays.sort() so it only sorts the array the method is using then sets min to array[0] and max to array[array.length-1].

Use @Named to differentiate between different objects of the same type bound in the same scope.

@Named("maxWaitTime")
public long maxWaitTimeMs;

@Named("minWaitTime")
public long minWaitTimeMs;

Without the @Named qualifier, the injector would not know which long to bind to which variable.

• If you want to create annotations that act like @Named, use the @Qualifier annotation when creating them.

• If you look at @Named, it is itself annotated with @Qualifier.

Simple, make a simple asp page with the designer (just for the beginning) Lets say the body is something like this:

<body>
    <form id="form1" runat="server">
    <div>
        <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
        <br />
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    </div>
    <p>
        <asp:Button ID="Button1" runat="server" Text="Button" />
    </p>
    </form>
</body>

Great, now every asp object IS an object. So you can access it in the asp's CS code. The asp's CS code is triggered by events (mostly). The class will probably inherit from System.Web.UI.Page

If you go to the cs file of the asp page, you'll see a protected void Page_Load(object sender, EventArgs e) ... That's the load event, you can use that to populate data into your objects when the page loads.

Now, go to the button in your designer (Button1) and look at its properties, you can design it, or add events from there. Just change to the events view, and create a method for the event.

The button is a web control Button Add a Click event to the button call it Button1Click:

void Button1Click(Object sender,EventArgs e) { }

Now when you click the button, this method will be called. Because ASP is object oriented, you can think of the page as the actual class, and the objects will hold the actual current data.

So if for example you want to access the text in TextBox1 you just need to call that object in the C# code:

String firstBox = TextBox1.Text;

In the same way you can populate the objects when event occur.

Now that you have the data the user posted in the textboxes , you can use regular C# SQL connections to add the data to your database.

You are looking for

MyList.Select(x=>x.Name).ToArray();

Since Select is an Extension method make sure to add that namespace by adding a

using System.Linq

to your file - then it will show up with Intellisense.

I needed to do this for an AWS ELB. After getting beaten up by the dialog many times, finally this is what worked for me:

openssl rsa -in server.key -text > private.pem
openssl x509 -inform PEM -in server.crt > public.pem

Thanks NCZ

Edit: As @floatingrock says

With AWS, don't forget to prepend the filename with file://. So it'll look like:

 aws iam upload-server-certificate --server-certificate-name blah --certificate-body file://path/to/server.crt --private-key file://path/to/private.key --path /cloudfront/static/

http://docs.aws.amazon.com/cli/latest/reference/iam/upload-server-certificate.html

This should help -

var json = "{'@STARTDATE': '2016-02-17 00:00:00.000',  '@ENDDATE': '2016-02-18 23:59:00.000' }";
var fdate = JObject.Parse(json)["@STARTDATE"];

If you want to trim specified number of spaces from left and right, you could do this:

def remove_outer_spaces(text, num_of_leading, num_of_trailing):
    text = list(text)
    for i in range(num_of_leading):
        if text[i] == " ":
            text[i] = ""
        else:
            break

    for i in range(1, num_of_trailing+1):
        if text[-i] == " ":
            text[-i] = ""
        else:
            break
    return ''.join(text)

txt1 = "   MY name is     "
print(remove_outer_spaces(txt1, 1, 1))  # result is: "  MY name is    "
print(remove_outer_spaces(txt1, 2, 3))  # result is: " MY name is  "
print(remove_outer_spaces(txt1, 6, 8))  # result is: "MY name is"

I use Redgate backup pro 7 tools for this purpose. you can create mirror from backup file in create tile on other location. and can copy backup file after create on network and on host storage automatically.

A simple date comparison in pure JS should be sufficient:

// Create date from input value
var inputDate = new Date("11/21/2011");

// Get today's date
var todaysDate = new Date();

// call setHours to take the time out of the comparison
if(inputDate.setHours(0,0,0,0) == todaysDate.setHours(0,0,0,0)) {
    // Date equals today's date
}

Here's a working JSFiddle.

You can LEFT JOIN the two tables. If there is no corresponding row in the second table, the values will be NULL.

SELECT id FROM partmaster LEFT JOIN product_details ON (...) WHERE product_details.part_num IS NULL

No, functions are not first class objects in java. You can do the same thing by implementing a handler class - this is how callbacks are implemented in the Swing etc.

There are however proposals for closures (the official name for what you're talking about) in future versions of java - Javaworld has an interesting article.

Strictly in reference to prefacing "transpose", by the book, either one will work; i.e., application.transpose() OR worksheetfunction.transpose(), and by experience, if you really like typing, application.WorksheetFunction.Transpose() will work also-

get_or_create() returns a tuple:

customer.source, created  = Source.objects.get_or_create(name="Website")

• created ? has a boolean value, is created or not.

• customer.source ? has an object of get_or_create() method.

Assuming a is a string. The Slice notation in python has the syntax -

list[<start>:<stop>:<step>]

So, when you do a[::-1], it starts from the end towards the first taking each element. So it reverses a. This is applicable for lists/tuples as well.

Example -

>>> a = '1234'
>>> a[::-1]
'4321'

Then you convert it to int and then back to string (Though not sure why you do that) , that just gives you back the string.

MySQL will assume the part before the equals references the columns named in the INSERT INTO clause, and the second part references the SELECT columns.

INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, 
                inact, inadur, inadist, 
                smlct, smldur, smldist, 
                larct, lardur, lardist, 
                emptyct, emptydur)
SELECT id, uid, t.location, t.animal, t.starttime, t.endtime, t.entct, 
       t.inact, t.inadur, t.inadist, 
       t.smlct, t.smldur, t.smldist, 
       t.larct, t.lardur, t.lardist, 
       t.emptyct, t.emptydur 
FROM tmp t WHERE uid=x
ON DUPLICATE KEY UPDATE entct=t.entct, inact=t.inact, ...

Firebird:

SELECT FIRST 10 * FROM MYTABLE

All of the other answers are great, I just want to give a cool example of one thing you can do with constexpr that is amazing. See-Phit (https://github.com/rep-movsd/see-phit/blob/master/seephit.h) is a compile time HTML parser and template engine. This means you can put HTML in and get out a tree that is able to be manipulated. Having the parsing done at compile time can give you a bit of extra performance.

From the github page example:

#include <iostream>
#include "seephit.h"
using namespace std;



int main()
{
  constexpr auto parser =
    R"*(
    <span >
    <p  color="red" height='10' >{{name}} is a {{profession}} in {{city}}</p  >
    </span>
    )*"_html;

  spt::tree spt_tree(parser);

  spt::template_dict dct;
  dct["name"] = "Mary";
  dct["profession"] = "doctor";
  dct["city"] = "London";

  spt_tree.root.render(cerr, dct);
  cerr << endl;

  dct["city"] = "New York";
  dct["name"] = "John";
  dct["profession"] = "janitor";

  spt_tree.root.render(cerr, dct);
  cerr << endl;
}

1. Remove pod name(which to remove) from Podfile and then
2. Open Terminal, set project folder path
3. Run pod install --no-integrate

Here is a solution for those, who want to remove it from the database with Entity Framework:

prods.RemoveWhere(s => s.ID == 1);

And the extension method itself:

using System;
using System.Linq;
using System.Linq.Expressions;
using Microsoft.EntityFrameworkCore;

namespace LivaNova.NGPDM.Client.Services.Data.Extensions
{
    public static class DbSetExtensions
    {
        public static void RemoveWhere<TEntity>(this DbSet<TEntity> entities, Expression<Func<TEntity, bool>> predicate) where TEntity : class
        {
            var records = entities
                .Where(predicate)
                .ToList();
            if (records.Count > 0)
                entities.RemoveRange(records);
        }
    }
}

P.S. This simulates the method RemoveAll() that's not available for DB sets of the entity framework.

This is incredible but real.

csrf filter is enabled by default and it actually blocks any POST, PUT or DELETE requests which do not include de csrf token.

Try using a GET instead of POST to confirm that this is it.

If this is so then allow any HTTP method:

@Throws(Exception::class)
override fun configure(http: HttpSecurity) {

    /**
     * Allow POST, PUT or DELETE request
     *
     * NOTE: csrf filter is enabled by default and it actually blocks any POST, PUT or DELETE requests
     * which do not include de csrf token.
     */
    http.csrf().disable()

}

If you are obtaining a 401 the most intuitive thing is to think that in the request you have No Auth or you are missing something in the headers regarding authorization.

But apparently there is an internal function that is filtering the HTTP methods that use POST and returns a 401. After fixing it I thought it was a cache issue with the status code but apparently not.

• Disable csrf
• Demo

What you wrote would get you the greatest id assuming they were unique and auto-incremented that would be fine assuming you are okay with inviting concurrency issues.
Since you're using MySQL as your database, there is the specific function LAST_INSERT_ID() which only works on the current connection that did the insert.
PHP offers a specific function for that too called mysql_insert_id.

To Completely Remove Android Studio from Windows:

Step 1: Run the Android Studio uninstaller

The first step is to run the uninstaller. Open the Control Panel and under Programs, select Uninstall a Program. After that, click on "Android Studio" and press Uninstall. If you have multiple versions, uninstall them as well.

Step 2: Remove the Android Studio files

To delete any remains of Android Studio setting files, in File Explorer, go to your user folder (%USERPROFILE%), and delete .android, .AndroidStudio and any analogous directories with versions on the end, i.e. .AndroidStudio1.2, as well as .gradle and .m2 if they exist.

Then go to %APPDATA% and delete the JetBrains directory.

Finally, go to C:\Program Files and delete the Android directory.

Step 3: Remove SDK

To delete any remains of the SDK, go to %LOCALAPPDATA% and delete the Android directory.

Step 4: Delete Android Studio projects

Android Studio creates projects in a folder %USERPROFILE%\AndroidStudioProjects, which you may want to delete.

Alternativly if your using bootstrap then you can just add align-middle to vertical align the element.

<button id="whaever" class="btn btn-large btn-primary" style="padding: 20px;" name="Continue" type="submit">Continue
    <i class="icon-ok align-middle" style="font-size:40px;"></i>
</button>

According to W3Schools, HTML 5 lets you do this using a new "srcdoc" attribute, but the browser support seems very limited.

Use the change event of the select:

$('#my_select').change(function()
{
   $(this).parents('td').css('background', '#000000');
});

export is used to set environment variables. For example:

export EDITOR=pico

Will set your default text editor to be the pico command.

Get the position of the first space:

int space1 = theString.IndexOf(' ');

The the position of the next space after that:

int space2 = theString.IndexOf(' ', space1 + 1);

Get the part of the string up to the second space:

string firstPart = theString.Substring(0, space2);

The above code put togehter into a one-liner:

string firstPart = theString.Substring(0, theString.IndexOf(' ', theString.IndexOf(' ') + 1));

If you get this error in PowerShell, it's most likely because you're using Resolve-Path to resolve a remote path, e.g.

 Resolve-Path \\server\share\path

In this case, Resolve-Path returns an object that, when converted to a string, doesn't return a valid path. It returns PowerShell's internal path:

> [string](Resolve-Path \\server\share\path)
Microsoft.PowerShell.Core\FileSystem::\\server\share\path

The solution is to use the ProviderPath property on the object returned by Resolve-Path:

> Resolve-Path \\server\share\path | Select-Object -ExpandProperty PRoviderPath
\\server\share\path
> (Resolve-Path \\server\share\path).ProviderPath
\\server\share\path

Please check your free space on your disk also. I had a same problem and finally I got I need to free up space to fix this.

You could designate a class for each cell in the second column.

<table>
<tr><td>Column 1</td><td class="col2">Col 2</td></tr>
<tr><td>Column 1</td><td class="col2">Col 2</td></tr>
<tr><td>Column 1</td><td class="col2">Col 2</td></tr>
<tr><td>Column 1</td><td class="col2">Col 2</td></tr>
</table>

Try this.

public class StopWatch { 

      private long startTime = 0;
      private long stopTime = 0;

      public StopWatch()
      {
            startTime = System.currentTimeMillis();
      }

      public void start() {
        startTime = System.currentTimeMillis();
      }

      public void stop() {
        stopTime = System.currentTimeMillis();
        System.out.println("StopWatch: " + getElapsedTime() + " milliseconds.");
        System.out.println("StopWatch: " + getElapsedTimeSecs() + " seconds.");
      }

      /**
       * @param process_name
       */
      public void stop(String process_name) {
            stopTime = System.currentTimeMillis();
            System.out.println(process_name + " StopWatch: " + getElapsedTime() + " milliseconds.");
            System.out.println(process_name + " StopWatch: " + getElapsedTimeSecs() + " seconds.");
      }      

      //elaspsed time in milliseconds
      public long getElapsedTime() {
          return stopTime - startTime;
      }

      //elaspsed time in seconds
      public double getElapsedTimeSecs() {
        double elapsed;
          elapsed = ((double)(stopTime - startTime)) / 1000;
        return elapsed;
      }
} 

Usage:

StopWatch watch = new StopWatch();
// do something
watch.stop();

Console:

StopWatch: 143 milliseconds.
StopWatch: 0.143 seconds.

Not javascript free, I am afraid too and my solution do require a js library, however, you can only use those files which you need rather than using them all, maybe best suited for those who are already using YUI for their projects or deciding which one to use. Have a look at: http://ciitronian.com/blog/programming/yui-button-mimicking-native-select-dropdown-avoid-width-problem/

My blog post also discusses other solutions as well, one is referenced back to here on stackoverflow, why I went back to create my own SELECT element is because of simple reason, I don't like mouseover expand events. Maybe if that helps anyone else too!

Using navigation controller to host a bar to dismiss the keyboard:

in the .h file:

UIBarButtonItem* dismissKeyboardButton;

in the .m file:

- (void)viewDidLoad {
    dismissKeyboardButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(dismissKeyboard)];
}

-(void)textViewDidBeginEditing:(UITextView *)textView {
    self.navigationItem.rightBarButtonItem = dismissKeyboardButton;
}

-(void)textFieldDidBeginEditing:(UITextField *)textField {
    self.navigationItem.rightBarButtonItem = dismissKeyboardButton;
}

-(void)dismissKeyboard {
    [self.textField resignFirstResponder];
    [self.textView resignFirstResponder];
    //or replace this with your regular right button
    self.navigationItem.rightBarButtonItem = nil;
}

Doesn't SELECT DISTINCT help? I suppose it would return the result you want.

There doesn't seem to be a standardized default value. I have the feeling the default is 0, and the timeout event left totally dependent on browser and network settings.

For IE, there is a timeout property for XMLHTTPRequests here. It defaults to null, and it says the network stack is likely to be the first to time out (which will not generate an ontimeout event by the way).

In addition to adding python's bin directory to $PATH variable, I also had to change the owner of that directory, to make it work. No idea why I wasn't the owner already.

chown -R ~/Library/Python/

Try adding a transform to the parent (doesn't have to do anything, could be a zero translation) and set the fixed child's width to 100%

body{ height:20000px }_x000D_
#wrapper {padding:10%;}_x000D_
#wrap{ _x000D_
    float: left;_x000D_
    position: relative;_x000D_
    width: 40%; _x000D_
    background:#ccc; _x000D_
    transform: translate(0, 0);_x000D_
}_x000D_
#fixed{ _x000D_
    position:fixed;_x000D_
    width:100%;_x000D_
    padding:0px;_x000D_
    height:10px;_x000D_
    background-color:#333;_x000D_
}

<div id="wrapper">_x000D_
    <div id="wrap">_x000D_
    Some relative item placed item_x000D_
    <div id="fixed"></div>_x000D_
    </div>_x000D_
</div>

Global variables are not extern nor static by default on C and C++. When you declare a variable as static, you are restricting it to the current source file. If you declare it as extern, you are saying that the variable exists, but are defined somewhere else, and if you don't have it defined elsewhere (without the extern keyword) you will get a link error (symbol not found).

Your code will break when you have more source files including that header, on link time you will have multiple references to varGlobal. If you declare it as static, then it will work with multiple sources (I mean, it will compile and link), but each source will have its own varGlobal.

What you can do in C++, that you can't in C, is to declare the variable as const on the header, like this:

const int varGlobal = 7;

And include in multiple sources, without breaking things at link time. The idea is to replace the old C style #define for constants.

If you need a global variable visible on multiple sources and not const, declare it as extern on the header, and then define it, this time without the extern keyword, on a source file:

Header included by multiple files:

extern int varGlobal;

In one of your source files:

int varGlobal = 7;

Another option would be:

SELECT * FROM [Village] WHERE PATINDEX('foo', [CastleType]) <> 0

To return a value from a VBScript function, assign the value to the name of the function, like this:

Function getNumber
    getNumber = "423"
End Function

According to the latest documentation about PyMongo titled Insert a Document (insert is deprecated) and following defensive approach, you should insert and update as follows:

result = mycollection.insert_one(post)
post = mycollection.find_one({'_id': result.inserted_id})

if post is not None:
    post['newfield'] = "abc"
    mycollection.save(post)

in restore wizard click "close existing connections to destination database"

in Detach Database wizard click "Drop connection" item.

What does res.render do and what does the html file look like?

res.render() function compiles your template (please don't use ejs), inserts locals there, and creates html output out of those two things.

Answering Edit 2 part.

// here you set that all templates are located in `/views` directory
app.set('views', __dirname + '/views');

// here you set that you're using `ejs` template engine, and the
// default extension is `ejs`
app.set('view engine', 'ejs');

// here you render `orders` template
response.render("orders", {orders: orders_json});

So, the template path is views/ (first part) + orders (second part) + .ejs (third part) === views/orders.ejs

Anyway, express.js documentation is good for what it does. It is API reference, not a "how to use node.js" book.
