To store the array values in cookie, first you need to convert them to string, so here is some options.

Storing cookies as JSON

Storing code

setcookie('your_cookie_name', json_encode($info), time()+3600);

Reading code

$data = json_decode($_COOKIE['your_cookie_name'], true);

JSON can be good choose also if you need read cookie in front end with JavaScript.

Actually you can use any encrypt_array_to_string/decrypt_array_from_string methods group that will convert array to string and convert string back to same array. For example you can also use explode/implode for array of integers.

Warning: Do not use serialize/unserialize

From PHP.net

Do not pass untrusted user input to unserialize(). - Anything that coming by HTTP including cookies is untrusted!

As an alternative solution, you can do it also without converting array to string.

setcookie('my_array[0]', 'value1' , time()+3600);
setcookie('my_array[1]', 'value2' , time()+3600);
setcookie('my_array[2]', 'value3' , time()+3600);

And after if you will print $_COOKIE variable, you will see the following

echo '<pre>';
print_r( $_COOKIE );
die();

Array
(   
    [my_array] => Array
        (
            [0] => value1
            [1] => value2
            [2] => value3
        )

)

This is documented PHP feature.

From PHP.net

Cookies names can be set as array names and will be available to your PHP scripts as arrays but separate cookies are stored on the user's system.

If you need this to work in a textarea the accepted solution will not work.

<textarea id='textarea'></textarea>

$("#textarea").append(formatJSON(JSON.stringify(jsonobject),true));

function formatJSON(json,textarea) {
    var nl;
    if(textarea) {
        nl = "

    var ret = "";
    var numquotes = 0;
    var betweenquotes = false;
    var firstquote = false;
    for (var i = 0; i < json.length; i++) {
        var c = json[i];
        if(c == '"') {
            numquotes ++;
            if((numquotes + 2) % 2 == 1) {
                betweenquotes = true;

            ret += c;
            ret += nl;
            continue;

            ret += c;
            continue;
        }
        ret += c;

    return ret;

if you have error in Sqlite built in python you can use Conda to solve this conflict

conda install sqlite

Replication is not very hard to create.

Here's some good tutorials:

http://www.ghacks.net/2009/04/09/set-up-mysql-database-replication/

http://dev.mysql.com/doc/refman/5.5/en/replication-howto.html

http://www.lassosoft.com/Beginners-Guide-to-MySQL-Replication

Here some simple rules you will have to keep in mind (there's more of course but that is the main concept):

1. Setup 1 server (master) for writing data.
2. Setup 1 or more servers (slaves) for reading data.

This way, you will avoid errors.

For example: If your script insert into the same tables on both master and slave, you will have duplicate primary key conflict.

You can view the "slave" as a "backup" server which hold the same information as the master but cannot add data directly, only follow what the master server instructions.

NOTE: Of course you can read from the master and you can write to the slave but make sure you don't write to the same tables (master to slave and slave to master).

I would recommend to monitor your servers to make sure everything is fine.

Let me know if you need additional help

Here's a simple method to do it: The (ip >> 8), (ip >> 16) and (ip >> 24) moves the 2nd, 3rd and 4th bytes into the lower order byte, while the & 0xFF isolates the least significant byte at each step.

void print_ip(unsigned int ip)
{
    unsigned char bytes[4];
    bytes[0] = ip & 0xFF;
    bytes[1] = (ip >> 8) & 0xFF;
    bytes[2] = (ip >> 16) & 0xFF;
    bytes[3] = (ip >> 24) & 0xFF;   
    printf("%d.%d.%d.%d\n", bytes[3], bytes[2], bytes[1], bytes[0]);        
}

There is an implied bytes[0] = (ip >> 0) & 0xFF; at the first step.

Use snprintf() to print it to a string.

I'll throw in my two cents for relative beginners or whatnot wanting a simple spl_autoload_register() setup without all the theory: Just create one php file for each class, name that php file the same as your class name, and keep your class files in the same directory as your php file in question, then this will work:

spl_autoload_register(function ($class_name) {
    require_once dirname(__FILE__) . DIRECTORY_SEPARATOR . $class_name . '.php';
});

Googling the pieces inside this function should answer how it works. PS: I use Linux, and this works on Linux. Windows folks should test it out first.

here the problem is model binding if you specify a class then the model binding can understand it during the post if it an integer or string then you have to specify the [FromBody] to bind it properly.

make the following changes in FormMethod

using (@Html.BeginForm("myMethod", "Home", FormMethod.Post, new { id = @item.JobId })){

}

and inside your home controller for binding the string you should specify [FromBody]

using System.Web.Http;
[HttpPost]
public FileStreamResult myMethod([FromBody]string id)
{
     // Set a local variable with the incoming data
     string str = id;

}

FromBody is available in System.Web.Http. make sure you have the reference to that class and added it in the cs file.

Maybe you can subclass your button and override your isEnabled variable. The advantage is that you can reuse in multiple places.

override var isEnabled: Bool {
     didSet {
         if isEnabled {
             self.alpha = 1
         } else {
             self.alpha = 0.2
         }
     }
 }

I use them sometimes as a syntax hack for Map instantiation:

Map map = new HashMap() {{
   put("key", "value");
}};

vs

Map map = new HashMap();
map.put("key", "value");

It saves some redundancy when doing a lot of put statements. However, I have also run into problems doing this when the outer class needs to be serialized via remoting.

The other answers are very complete, and you should definitely use them if you're trying to find the last character of a string. But if you're just trying to use a conditional (e.g. is the last character 'g'), you could also do the following:

if (str.endsWith("g")) {

or, strings

if (str.endsWith("bar")) {

...How can I step through my javascript code line by line using Google Chromes developer tools without it going into javascript libraries?...

For the record: At this time (Feb/2015) both Google Chrome and Firefox have exactly what you (and I) need to avoid going inside libraries and scripts, and go beyond the code that we are interested, It's called Black Boxing:

When you blackbox a source file, the debugger will not jump into that file when stepping through code you're debugging.

More info:

• Chrome: Blackbox JavaScript Source Files
• Firefox: Black box libraries in the Debugger

Found it:

~/Library/Application Support/iPhone Simulator/User/

The current spec of the CSS 3 Lists module does specify the ::marker pseudo-element which would do exactly what you want; FF has been tested to not support ::marker and I doubt that either Safari or Opera has it. IE, of course, does not support it.

So right now, the only way to do this is to use an image with list-style-image.

I guess you could wrap the contents of an li with a span and then you could set the color of each, but that seems a little hackish to me.

The best practice for checking the react native environment information.

react-native info

which will give the information

React Native Environment Info:
System:
  OS: Linux 4.15 Ubuntu 18.04.1 LTS (Bionic Beaver)
  CPU: (8) x64 Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz
  Memory: 2.08 GB / 7.67 GB
  Shell: 4.4.19 - /bin/bash

  Node: 8.10.0 - /usr/bin/node
  Yarn: 1.12.3 - /usr/bin/yarn

  react-native: 0.56.0 => 0.56.0

just simple replace your class with this.

}

I have same issue and i solved it.

I know, this has been asked and answered long ago, however if anyone is interested, here is my solution - custom set class backed by HashMap:

http://pastebin.com/Qv6S91n9

You can easily implement all other Set methods.

I know this is a very old question. I was searching through the proper answer and couldn't find anything that is simple and satisfactory. Took me some time but was able to jot down something.

function denomination(coins, original_amount){
    var original_amount = original_amount;
    var original_best = [ ];

    for(var i=0;i<coins.length; i++){
      var amount = original_amount;
      var best = [ ];
      var tempBest = [ ]
      while(coins[i]<=amount){
        amount = amount - coins[i];
        best.push(coins[i]);
      }
      if(amount>0 && coins.length>1){
        tempBest = denomination(coins.slice(0,i).concat(coins.slice(i+1,coins.length)), amount);
        //best = best.concat(denomination(coins.splice(i,1), amount));
      }
      if(tempBest.length!=0 || (best.length!=0 && amount==0)){
        best = best.concat(tempBest);
        if(original_best.length==0 ){
          original_best = best
        }else if(original_best.length > best.length ){
          original_best = best;
        }  
      }
    }
    return original_best;  
  }
  denomination( [1,10,3,9] , 19 );

This is a javascript solution and uses recursion.

It will compile to this:

React.createElement('div', this.props, 'Content Here');

As you can see above, it passes all it's props to the div.

from celery.task.control import inspect
def key_in_list(k, l):
    return bool([True for i in l if k in i.values()])

def check_task(task_id):
    task_value_dict = inspect().active().values()
    for task_list in task_value_dict:
        if self.key_in_list(task_id, task_list):
             return True
    return False

My answer is an amalgamation of the above two with extension to drawing sphere of user-defined opacity and some annotation. It finds application in b-vector visualization on a sphere for magnetic resonance image (MRI). Hope you find it useful:

from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np

fig = plt.figure()
ax = fig.gca(projection='3d')

# draw sphere
u, v = np.mgrid[0:2*np.pi:50j, 0:np.pi:50j]
x = np.cos(u)*np.sin(v)
y = np.sin(u)*np.sin(v)
z = np.cos(v)
# alpha controls opacity
ax.plot_surface(x, y, z, color="g", alpha=0.3)


# a random array of 3D coordinates in [-1,1]
bvecs= np.random.randn(20,3)

# tails of the arrows
tails= np.zeros(len(bvecs))

# heads of the arrows with adjusted arrow head length
ax.quiver(tails,tails,tails,bvecs[:,0], bvecs[:,1], bvecs[:,2],
          length=1.0, normalize=True, color='r', arrow_length_ratio=0.15)

ax.set_xlabel('X-axis')
ax.set_ylabel('Y-axis')
ax.set_zlabel('Z-axis')

ax.set_title('b-vectors on unit sphere')

plt.show()

This is more of a warning than an answer.
Having seen in the other answers my_list = [None] * 10, I was tempted and set up an array like this speakers = [['','']] * 10 and came to regret it immensely as the resulting list did not behave as I thought it should.
I resorted to:

speakers = []
for i in range(10):
    speakers.append(['',''])

As [['','']] * 10 appears to create an list where subsequent elements are a copy of the first element.
for example:

>>> n=[['','']]*10
>>> n
[['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', '']]
>>> n[0][0] = "abc"
>>> n
[['abc', ''], ['abc', ''], ['abc', ''], ['abc', ''], ['abc', ''], ['abc', ''], ['abc', ''], ['abc', ''], ['abc', ''], ['abc', '']]
>>> n[0][1] = "True"
>>> n
[['abc', 'True'], ['abc', 'True'], ['abc', 'True'], ['abc', 'True'], ['abc', 'True'], ['abc', 'True'], ['abc', 'True'], ['abc', 'True'], ['abc', 'True'], ['abc', 'True']]

Whereas with the .append option:

>>> n=[]
>>> for i in range(10):
...  n.append(['',''])
... 
>>> n
[['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', '']]
>>> n[0][0] = "abc"
>>> n
[['abc', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', '']]
>>> n[0][1] = "True"
>>> n
[['abc', 'True'], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', ''], ['', '']]

I'm sure that the accepted answer by ninjagecko does attempt to mention this, sadly I was too thick to understand.
Wrapping up, take care!

 void main(){
  var x = "4";
  int number = int.parse(x);//STRING to INT

  var y = "4.6";
  double doubleNum = double.parse(y);//STRING to DOUBLE

  var z = 55;
  String myStr = z.toString();//INT to STRING
}

int.parse() and double.parse() can throw an error when it couldn't parse the String

Use serialize and deserialize methods in SerializationUtils from commons-lang.

There is a much easier and more compact solution for multilevel prototype lookup, but it requires Proxy support. Usage: SUPER(<instance>).<method>(<args>), for example, assuming two classes A and B extends A with method m: SUPER(new B).m().

function SUPER(instance) {
    return new Proxy(instance, {
        get(target, prop) {
            return Object.getPrototypeOf(Object.getPrototypeOf(target))[prop].bind(target);
        }
    });
}

I worked in a place where the coding standard was one giant WTF: strange Hungarian notation, prefixing globals with 'g' and members with 'm' (so there were gems like gsSomeVariable), adding 'ref string sError' to every single function, instead of throwing exceptions (which was a BIG nono!).

The killer, though, was prefixing the function parameters with I_ for input parameters, and O_ for output parameters.

I work now in a much better place :)

You can use calc to position element relative to center. For example if you want to position element 200px right from the center .. you can do this :

#your_element{
    position:absolute;
    left: calc(50% + 200px);
}

Dont forget this

When you use signs + and - you must have one blank space between sign and number, but when you use signs * and / there is no need for blank space.

When you do self.button = Button(...).grid(...), what gets assigned to self.button is the result of the grid() command, not a reference to the Button object created.

You need to assign your self.button variable before packing/griding it. It should look something like this:

self.button = Button(self,text="Click Me",command=self.color_change,bg="blue")
self.button.grid(row = 2, column = 2, sticky = W)

Solutions using value.toUpperCase seem to have the problem that typing text into the field resets the cursor position to the end of the text. Solutions using text-transform seem to have the problem that the text submitted to the server is still potentially lowercase. This solution avoids those problems:

function handleInput(e) {_x000D_
   var ss = e.target.selectionStart;_x000D_
   var se = e.target.selectionEnd;_x000D_
   e.target.value = e.target.value.toUpperCase();_x000D_
   e.target.selectionStart = ss;_x000D_
   e.target.selectionEnd = se;_x000D_
}

<input type="text" id="txtTest" oninput="handleInput(event)" />

Update

As of 17th May 2017 the README of autoenv states that direnv is probably the better option and implies autoenv is no longer maintained.

Old answer

I wrote autoenv to do exactly this:

https://github.com/kennethreitz/autoenv

Based on git diff --name-status I wrote the git-diffview git extension that renders a hierarchical tree view of what changed between two paths.

this is an out of topic answer, but, for those who are interested, it maybe valuable.

As in @John Kugelman's answer, % is related to job specification. how to efficiently find that? use less's &pattern command, seems man use less pager (not that sure), in man bash type &% then type Enter will only show lines that containing '%', to reshow all, type &. then Enter.

This worked for me in swift:

let dirPaths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
println("App Path: \(dirPaths)")

An old thread, sure, but a popular one apparently. It's 2020 now and none of these answers have addressed the issue of unreadable code. @pimvdb's answer takes up less lines, but it's also pretty complicated to follow. For easier debugging and better readability, I should suggest refactoring the OP's code to something like this, and adopting an early return pattern, as this is likely the main reason you were unsure of why the were getting undefined:

function validatePassword() {
   const password = document.getElementById("password");
   const confirm_password = document.getElementById("password_confirm");

   if (password.value.length === 0) {
      return false;
   }

   if (password.value !== confirm_password.value) {
      return false;
   }
  
   return true;
}

Swift 4 solution:

UIApplication.shared.open(NSURL(string:"http://yo.lo")! as URL, options: [String : Any](), completionHandler: nil)

You can create a linked server and reference the table in the other instance using its fully qualified Server.Catalog.Schema.Table name.

You need to start the SQL Server manually. Press

windows + R

type

sqlservermanager12.msc

right click ->Start

Service configuration does not display SQL Server?

They are access modifiers and help us implement Encapsulation (or information hiding). They tell the compiler which other classes should have access to the field or method being defined.

private - Only the current class will have access to the field or method.

protected - Only the current class and subclasses (and sometimes also same-package classes) of this class will have access to the field or method.

public - Any class can refer to the field or call the method.

This assumes these keywords are used as part of a field or method declaration within a class definition.

In Java, == always just compares two references (for non-primitives, that is) - i.e. it tests whether the two operands refer to the same object.

However, the equals method can be overridden - so two distinct objects can still be equal.

For example:

String x = "hello";
String y = new String(new char[] { 'h', 'e', 'l', 'l', 'o' });

System.out.println(x == y); // false
System.out.println(x.equals(y)); // true

Additionally, it's worth being aware that any two equal string constants (primarily string literals, but also combinations of string constants via concatenation) will end up referring to the same string. For example:

String x = "hello";
String y = "he" + "llo";
System.out.println(x == y); // true!

Here x and y are references to the same string, because y is a compile-time constant equal to "hello".

Try this, add these lines to your edit text view, i'll add mine. make sure you understand it

android:overScrollMode="always"
android:scrollbarStyle="insideInset"
android:scrollbars="vertical"

<EditText
    android:inputType="textMultiLine"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/editText_newprom_description"
    android:padding="10dp"
    android:lines="5"
    android:overScrollMode="always"
    android:scrollbarStyle="insideInset"
    android:minLines="5"
    android:gravity="top|left"
    android:scrollbars="vertical"
    android:layout_marginBottom="20dp"/>

and on your java class make on click listner to this edit text as follows, i'll add mine, chane names according to yours.

EditText description;
description = (EditText)findViewById(R.id.editText_newprom_description);

description.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {

                view.getParent().requestDisallowInterceptTouchEvent(true);
                switch (motionEvent.getAction() & MotionEvent.ACTION_MASK){
                    case MotionEvent.ACTION_UP:
                        view.getParent().requestDisallowInterceptTouchEvent(false);
                        break;
                }

                return false;
            }

        });

this works fine for me

For best results, you should use both TextFX XML tidy and XML tools pretty print. Here's how and why:

1.TextFX -> TextFX HTML Tidy -> Tidy: reindent XML

TextFX has the benefit of wrapping long lines, which XML Tools does not do, but it doesn't indent those new lines correctly.

2. XML Tools -> Pretty print (Text indent)

XML Tools complements TextFX by indenting the newly wrapped lines nicely.

Scanner scan = new Scanner(System.in);
        int i = scan.nextInt();
        Double d = scan.nextDouble();


        String newStr = "";
        Scanner charScanner = new Scanner( System.in ).useDelimiter( "(\\b|\\B)" ) ;
        while( charScanner.hasNext() ) { 
            String  c = charScanner.next();

            if (c.equalsIgnoreCase("\r")) {
                break;
            }
            else {
                newStr += c;    
            }
        }

        System.out.println("String: " + newStr);
        System.out.println("Int: " + i);
        System.out.println("Double: " + d);

This code works fine

The == token in C# is used for two different equality-check operators. When the compiler encounters that token, it will check whether either of the types being compared has implemented an equality-operator overload for either the specific combination types being compared(*), or for a combination of types to which both types can be converted. If the compiler finds such an overload it will use it. Otherwise, if the two types are both reference types and they are not unrelated classes (either may be an interface, or they may be related classes), the compiler will regard == as a reference-comparison operator. If neither condition applies, compilation will fail.

Note that some other languages use separate tokens for the two equality-check operators. In VB.NET, for example, the = token is used within expressions solely for the overloadable equality-check operator, and Is is used as a reference-test or null-test operator. An to use = on a type which does not override the equality-check operator will fail, as will attempting to use Is for any purpose other than testing reference equality or nullity.

(*)Types generally only overload equality for comparison with themselves, but it may be useful for types to overload the equality operator for comparison with other particular types; for example, int could have (and IMHO should have but didn't) defined an equality operators for comparison with float, so that 16777217 would not report itself equal to 16777216f. As it is, since no such operator is defined, C# will promote the int to float, rounding it to 16777216f before the equality-check operator sees it; that operator then sees two equal floating-point numbers and reports them as equal, unaware of the rounding that took place.

Just a tip: using http_response_code is much easier to remember than writing the full header:

http_response_code(301);
header('Location: /option-a'); 
exit;

Just add ExecJS and the Ruby Racer in your gem file and run bundle install after.

gem 'execjs'

gem 'therubyracer'

Everything should be fine after.

Allowing the user to click through a div to the underlying element depends on the browser. All modern browsers, including Firefox, Chrome, Safari, and Opera, understand pointer-events:none.

For IE, it depends on the background. If the background is transparent, clickthrough works without you needing to do anything. On the other hand, for something like background:white; opacity:0; filter:Alpha(opacity=0);, IE needs manual event forwarding.

See a JSFiddle test and CanIUse pointer events.

This exception says that you are trying to deserialize the object "Address" from string "\"\"" instead of an object description like "{…}". The deserializer can't find a constructor of Address with String argument. You have to replace "" by {} to avoid this error.

In most cases @tster's answer will suffice. However, I had a scenario where I wanted to update a row without first retrieving it.

My situation is this: I've got a table where I want to "lock" a row so that only a single user at a time will be able to edit it in my app. I'm achieving this by saying

update items set status = 'in use', lastuser = @lastuser, lastupdate = @updatetime where ID = @rowtolock and @status = 'free'

The reason being, if I were to simply retrieve the row by ID, change the properties and then save, I could end up with two people accessing the same row simultaneously. This way, I simply send and update claiming this row as mine, then I try to retrieve the row which has the same properties I just updated with. If that row exists, great. If, for some reason it doesn't (someone else's "lock" command got there first), I simply return FALSE from my method.

I do this by using context.Database.ExecuteSqlCommand which accepts a string command and an array of parameters.

Just wanted to add this answer to point out that there will be scenarios in which retrieving a row, updating it, and saving it back to the DB won't suffice and that there are ways of running a straight update statement when necessary.

First, you need to import from inspect and os

from inspect import getsourcefile
from os.path import abspath

Next, wherever you want to find the source file from you just use

abspath(getsourcefile(lambda:0))

My response is fairly late. I faced the same problem. I am on Windows 10. This is what I did:

• Open a new Command prompt (CMD.EXE)
• Set the environment variables . set myvar1=myvalue1
• Launch VS Code from that Command prompt by typing code and then press ENTER
• VS code was launched and it inherited all the custom variables that I had set in the parent CMD window

Optionally, you can also use the Control Panel -> System properties window to set the variables on a more permanent basis

Hope this helps.

What if you had a <tbody> and a <tfoot>?

Such as:

<table>
    <tbody>
        <tr><td>Foo</td></tr>
    </tbody>
    <tfoot>
        <tr><td>footer information</td></tr>
    </tfoot>
</table>

Then it would insert your new row in the footer - not to the body.

Hence the best solution is to include a <tbody> tag and use .append, rather than .after.

$("#myTable > tbody").append("<tr><td>row content</td></tr>");

This is very simple to do:

import matplotlib.pyplot as plt

plt.plot(<X AXIS VALUES HERE>, <Y AXIS VALUES HERE>, 'line type', label='label here')
plt.plot(<X AXIS VALUES HERE>, <Y AXIS VALUES HERE>, 'line type', label='label here')
plt.legend(loc='best')
plt.show()

You can keep adding plt.plot as many times as you like. As for line type, you need to first specify the color. So for blue, it's b. And for a normal line it's -. An example would be:

plt.plot(total_lengths, sort_times_heap, 'b-', label="Heap")

However, if you do end up using rm instead of git rm. You can skip the git add and directly commit the changes using:

git commit -a

Checking if v contains the element x:

#include <algorithm>

if(std::find(v.begin(), v.end(), x) != v.end()) {
    /* v contains x */
} else {
    /* v does not contain x */
}

Checking if v contains elements (is non-empty):

if(!v.empty()){
    /* v is non-empty */
} else {
    /* v is empty */
}

You can run easy_install to install python packages in your home directory even without root access. There's a standard way to do this using site.USER_BASE which defaults to something like $HOME/.local or $HOME/Library/Python/2.7/bin and is included by default on the PYTHONPATH

To do this, create a .pydistutils.cfg in your home directory:

cat > $HOME/.pydistutils.cfg <<EOF
[install]
user=1
EOF

Now you can run easy_install without root privileges:

easy_install boto

Alternatively, this also lets you run pip without root access:

pip install boto

This works for me.

You can run the pipenv command with the --rm option as in:

pipenv --rm

This will remove the virtualenv created for you under ~/.virtualenvs

See https://pipenv.kennethreitz.org/en/latest/cli/#cmdoption-pipenv-rm

It's part of an evolution.

Originally, Python items() built a real list of tuples and returned that. That could potentially take a lot of extra memory.

Then, generators were introduced to the language in general, and that method was reimplemented as an iterator-generator method named iteritems(). The original remains for backwards compatibility.

One of Python 3’s changes is that items() now return views, and a list is never fully built. The iteritems() method is also gone, since items() in Python 3 works like viewitems() in Python 2.7.

I have tried a few fixes and none of them works. My version is simple: add a new unused parameter into query parameters

            if (force) {
                let key = 'time';

                while (key in filter) {
                    key = '_' + key;
                }

                filter[key] = Date.now();
            }

            this.router.navigate(['.', { filter: JSON.stringify(filter) }]);

Setting PATH right before the command line in my crontab worked for me:

* * * * * PATH=$PATH:/usr/local/bin:/path/to/some/thing

Use response.write method in the code-behind.

As I understand Copy-Item -Exclude then you are doing it correct. What I usually do, get 1'st, and then do after, so what about using Get-Item as in

Get-Item -Path $copyAdmin -Exclude $exclude |
Copy-Item  -Path $copyAdmin -Destination $AdminPath -Recurse -force

If use generic repository

> lstModule = _ModuleRepository.GetAll().OrderBy(x => new { x.Level,
> x.Rank}).ToList();

else

> _db.Module.Where(x=> ......).OrderBy(x => new { x.Level, x.Rank}).ToList();

I imagine this like that:

<html>
<head>
<script>
var frame_loaded = 0;
function setFrameLoaded()
{
   frame_loaded = 1;
   alert("Iframe is loaded");
}
$('#click').click(function(){
   if(frame_loaded == 1)
    console.log('iframe loaded')
   } else {
    console.log('iframe not loaded')
   }
})
</script>
</head>
<button id='click'>click me</button>

<iframe id='MainPopupIframe' onload='setFrameLoaded();' src='http://...' />...</iframe>

Use OnClicklistener or you can use android:onClick="myMethod" in your button's xml code from which you going to open a new layout. So when that button is clicked your myMethod function will be called automatically. Your myMethod function in class look like this.

public void myMethod(View v) {
Intent intent=new Intent(context,SecondActivty.class);
startActivity(intent);
}

And in that SecondActivity.class set new layout in contentview.

When parsing its configuration file, the expression ${MY_HOME} will be expanded to the value of the system property named MY_HOME, not the system environment variable. There's a difference between the two.

To achieve this in a clean way, you'll have to add something like this to the JVM invocation line:

-DMY_HOME=$MY_HOME

That would define the Java system property MY_HOME to contain the value of the environment variable MY_HOME.

#header.overlay {
    background-color: SlateGray;
    position:relative;
    width: 100%;
    height: 100%;
    opacity: 0.20;
    -moz-opacity: 20%;
    -webkit-opacity: 20%;
    z-index: 2;
}

Something like this. Just add the overlay class to the header, obviously.

On github there is also a secret way...

You can filter commits by author in the commit view by appending param ?author=github_handle. For example, the link https://github.com/dynjs/dynjs/commits/master?author=jingweno shows a list of commits to the Dynjs project

just do it as follows in your html write:

<button ng-click="going()">goto</button>

And in your controller, add $state as follows:

.controller('homeCTRL', function($scope, **$state**) {

$scope.going = function(){

$state.go('your route');

}

})

Well, I don't understand why are you used transaction in case when you make a select.

Transaction is useful when you make changes (add, edit or delete) data from database.

Remove transaction unless you use insert, update or delete statements

If you have something like this:

var json = [ {a:b, c:d}, {e:f, g:h, ...}, {..}, ... ]

then, you can do:

alert(json.length)

(copy-paste/adapted from https://stackoverflow.com/a/24048772/1733117).

First you can subclass urllib2.BaseHandler or urllib2.HTTPBasicAuthHandler, and implement http_request so that each request has the appropriate Authorization header.

import urllib2
import base64

class PreemptiveBasicAuthHandler(urllib2.HTTPBasicAuthHandler):
    '''Preemptive basic auth.

    Instead of waiting for a 403 to then retry with the credentials,
    send the credentials if the url is handled by the password manager.
    Note: please use realm=None when calling add_password.'''
    def http_request(self, req):
        url = req.get_full_url()
        realm = None
        # this is very similar to the code from retry_http_basic_auth()
        # but returns a request object.
        user, pw = self.passwd.find_user_password(realm, url)
        if pw:
            raw = "%s:%s" % (user, pw)
            auth = 'Basic %s' % base64.b64encode(raw).strip()
            req.add_unredirected_header(self.auth_header, auth)
        return req

    https_request = http_request

Then if you are lazy like me, install the handler globally

api_url = "http://api.foursquare.com/"
api_username = "johndoe"
api_password = "some-cryptic-value"

auth_handler = PreemptiveBasicAuthHandler()
auth_handler.add_password(
    realm=None, # default realm.
    uri=api_url,
    user=api_username,
    passwd=api_password)
opener = urllib2.build_opener(auth_handler)
urllib2.install_opener(opener)

from subprocess import Popen, PIPE
from tempfile import SpooledTemporaryFile as tempfile
f = tempfile()
f.write('one\ntwo\nthree\nfour\nfive\nsix\n')
f.seek(0)
print Popen(['/bin/grep','f'],stdout=PIPE,stdin=f).stdout.read()
f.close()

You can use a Dictionary to keep track of the keys and values.

For instance...

dictOfStuff = {} ##Make a Dictionary

x = "Buffalo" ##OR it can equal the input of something, up to you.

dictOfStuff[x] = 4 ##Get the dict spot that has the same key ("name") as what X is equal to. In this case "Buffalo". and set it to 4. Or you can set it to  what ever you like

print(dictOfStuff[x]) ##print out the value of the spot in the dict that same key ("name") as the dictionary.

A dictionary is very similar to a real life dictionary. You have a word and you have a definition. You can look up the word and get the definition. So in this case, you have the word "Buffalo" and it's definition is 4. It can work with any other word and definition. Just make sure you put them into the dictionary first.

edit to my previous answer: if you want to count a function's invocations, you might want to try:

var countMe = ( function() {
  var c = 0;

  return function() {
    c++;
    return c;
  }
})();

alert(countMe()); // Alerts "1"
alert(countMe()); // Alerts "2"

Here, c serves as the counter, and you do not have to use arguments.callee.

If you're downloading text then I'd recommend using the WebClient and get a streamreader to the text:

        WebClient web = new WebClient();
        System.IO.Stream stream = web.OpenRead("http://www.yoursite.com/resource.txt");
        using (System.IO.StreamReader reader = new System.IO.StreamReader(stream))
        {
            String text = reader.ReadToEnd();
        }

If this is taking a long time then it is probably a network issue or a problem on the web server. Try opening the resource in a browser and see how long that takes. If the webpage is very large, you may want to look at streaming it in chunks rather than reading all the way to the end as in that example. Look at http://msdn.microsoft.com/en-us/library/system.io.stream.read.aspx to see how to read from a stream.

The pandoc manual explains how to link to your headers, using their identifier. I did not check support of this by other parsers, but it was reported that it does not work on github.

The identifier can be specified manually:

## my heading text {#mht}

Some normal text here,
including a [link to the header](#mht).

or you can use the auto-generated identifier (in this case #my-heading-text). Both are explained in detail in the pandoc manual.

NOTE: This only works when converting to HTML, LaTex, ConTeXt, Textile or AsciiDoc.

Including the header afxwin.h signalizes use of MFC. The following instructions (based on those on CodeProject.com) could help to get MFC code compiling:

1. Download and install the Windows Driver Kit.

2. Select menu Tools > Options… > Projects and Solutions > VC++ Directories.

3. In the drop-down menu Show directories for select Include files.

4. Add the following paths (replace $(WDK_directory) with the directory where you installed Windows Driver Kit in the first step):

   $(WDK_directory)\inc\mfc42
   $(WDK_directory)\inc\atl30
   

   

5. In the drop-down menu Show directories for select Library files and add (replace $(WDK_directory) like before):

   $(WDK_directory)\lib\mfc\i386
   $(WDK_directory)\lib\atl\i386
   

   

6. In the $(WDK_directory)\inc\mfc42\afxwin.inl file, edit the following lines (starting from 1033):

   _AFXWIN_INLINE CMenu::operator==(const CMenu& menu) const
       { return ((HMENU) menu) == m_hMenu; }
   _AFXWIN_INLINE CMenu::operator!=(const CMenu& menu) const
       { return ((HMENU) menu) != m_hMenu; }
   

   to

   _AFXWIN_INLINE BOOL CMenu::operator==(const CMenu& menu) const
       { return ((HMENU) menu) == m_hMenu; }
   _AFXWIN_INLINE BOOL CMenu::operator!=(const CMenu& menu) const
       { return ((HMENU) menu) != m_hMenu; }
   

   In other words, add BOOL after _AFXWIN_INLINE.

MySQL WorkBench is free software and is developed by Oracle, you can import an SQL File or specify a database and it will generate an SQL Diagram which you can move around to make it more visually appealing. It runs on GNU/Linux and Windows and it's free and has a professional look..

If you need to print it and don't need a newline, you can use:

printf $(md5sum filename)

So the length is between 10 16-bit chars, and 40 hex digits.

In any case decide the format you are going to store, and make the field a fixed size based on that format. That way you won't have any wasted space.

  ExcelApp.Sheets[1].Range[ExcelApp.Sheets[1].Cells[1, 1], ExcelApp.Sheets[1].Cells[70, 15]].Cells.HorizontalAlignment =
                 Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignCenter;

This works fine for me.

Try this:

$(document).ready(function(){
    var yourArray = [];
    $("span.HOEnZb").find("div").each(function(){
        if(($.trim($(this).text()).length>0)){
         yourArray.push($(this).text());
        }
    });
});

DEMO

You'll want to modify the manifest that gets embedded in the program. This works on Visual Studio 2008 and higher: Project + Add New Item, select "Application Manifest File". Change the <requestedExecutionLevel> element to:

 <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

The user gets the UAC prompt when they start the program. Use wisely; their patience can wear out quickly.

There are several answers that cover how to solve this if you have a UNIQUE index that you can check against with ON DUPLICATE KEY or INSERT IGNORE. That is not always the case, and as UNIQUE has a length constraint (1000 bytes) you might not be able to change that. For example, I had to work with metadata in WordPress (wp_postmeta).

I finally solved it with two queries:

UPDATE wp_postmeta SET meta_value = ? WHERE meta_key = ? AND post_id = ?;
INSERT INTO wp_postmeta (post_id, meta_key, meta_value) SELECT DISTINCT ?, ?, ? FROM wp_postmeta WHERE NOT EXISTS(SELECT * FROM wp_postmeta WHERE meta_key = ? AND post_id = ?);

Query 1 is a regular UPDATE query with no effect when the dataset in question is not there. Query 2 is an INSERT which depends on a NOT EXISTS, i.e. the INSERT is only executed when the dataset doesn't exist.

You're not supplying it with an array in your example. The following compiles fine:

public @interface SampleAnnotation {
    String[] sampleValues();
}

public class Values {
    public static final String val0 = "A";
    public static final String val1 = "B";

    @SampleAnnotation(sampleValues={ val0, val1 })
    public void foo() {
    }
}

At this time, I would answer "no" or "with difficulty", but that could change over time as the android NFC API evolves.

There are three modes of NFC interaction:

1. Reader-Writer: The phone reads tags and writes to them. It's not emulating a card instead an NFC reader/writer device. Hence, you can't emulate a tag in this mode.

2. Peer-to-peer: the phone can read and pass back ndef messages. If the tag reader supports peer-to-peer mode, then the phone could possibly act as a tag. However, I'm not sure if android uses its own protocol on top of the LLCP protocol (NFC logical link protocol), which would then prevent most readers from treating the phone as an nfc tag.

3. Card-emulation mode: the phone uses a secure element to emulate a smart card or other contactless device. I am not sure if this is launched yet, but could provide promising. However, using the secure element might require the hardware vendor or some other person to verify your app / give it permissions to access the secure element. It's not as simple as creating a regular NFC android app.

More details here: http://www.mail-archive.com/[email protected]/msg152222.html

A real question would be: why are you trying to emulate a simple old nfc tag? Is there some application I'm not thinking of? Usually, you'd want to emulate something like a transit card, access key, or credit card which would require a secure element (I think, but not sure).

Switch statements with String cases have been implemented in Java SE 7, at least 16 years after they were first requested. A clear reason for the delay was not provided, but it likely had to do with performance.

Implementation in JDK 7

The feature has now been implemented in javac with a "de-sugaring" process; a clean, high-level syntax using String constants in case declarations is expanded at compile-time into more complex code following a pattern. The resulting code uses JVM instructions that have always existed.

A switch with String cases is translated into two switches during compilation. The first maps each string to a unique integer—its position in the original switch. This is done by first switching on the hash code of the label. The corresponding case is an if statement that tests string equality; if there are collisions on the hash, the test is a cascading if-else-if. The second switch mirrors that in the original source code, but substitutes the case labels with their corresponding positions. This two-step process makes it easy to preserve the flow control of the original switch.

Switches in the JVM

For more technical depth on switch, you can refer to the JVM Specification, where the compilation of switch statements is described. In a nutshell, there are two different JVM instructions that can be used for a switch, depending on the sparsity of the constants used by the cases. Both depend on using integer constants for each case to execute efficiently.

If the constants are dense, they are used as an index (after subtracting the lowest value) into a table of instruction pointers—the tableswitch instruction.

If the constants are sparse, a binary search for the correct case is performed—the lookupswitch instruction.

In de-sugaring a switch on String objects, both instructions are likely to be used. The lookupswitch is suitable for the first switch on hash codes to find the original position of the case. The resulting ordinal is a natural fit for a tableswitch.

Both instructions require the integer constants assigned to each case to be sorted at compile time. At runtime, while the O(1) performance of tableswitch generally appears better than the O(log(n)) performance of lookupswitch, it requires some analysis to determine whether the table is dense enough to justify the space–time tradeoff. Bill Venners wrote a great article that covers this in more detail, along with an under-the-hood look at other Java flow control instructions.

Before JDK 7

Prior to JDK 7, enum could approximate a String-based switch. This uses the static valueOf method generated by the compiler on every enum type. For example:

Pill p = Pill.valueOf(str);
switch(p) {
  case RED:  pop();  break;
  case BLUE: push(); break;
}

Here's a simplest example from ASP.NET Community, this gave me a clear understanding on the concept....

what difference does this make?

For an example of this, here is a way to put focus on a text box on a page when the page is loaded into the browser—with Visual Basic using the RegisterStartupScript method:

Page.ClientScript.RegisterStartupScript(Me.GetType(), "Testing", _ 
"document.forms[0]['TextBox1'].focus();", True)

This works well because the textbox on the page is generated and placed on the page by the time the browser gets down to the bottom of the page and gets to this little bit of JavaScript.

But, if instead it was written like this (using the RegisterClientScriptBlock method):

Page.ClientScript.RegisterClientScriptBlock(Me.GetType(), "Testing", _
"document.forms[0]['TextBox1'].focus();", True)

Focus will not get to the textbox control and a JavaScript error will be generated on the page

The reason for this is that the browser will encounter the JavaScript before the text box is on the page. Therefore, the JavaScript will not be able to find a TextBox1.

One obvious and straightforward possibility is to use "if-else conditions". In that example

x <- c(1, 2, 4)
y <- c(1, 4, 5)
w <- ifelse(x <= 1, "good", ifelse((x >= 3) & (x <= 5), "bad", "fair"))
data.frame(x, y, w)

** For the additional question in the edit** Is that what you expect ?

> d1 <- c("e", "c", "a")
> d2 <- c("e", "a", "b")
> 
> w <- ifelse((d1 == "e") & (d2 == "e"), 1, 
+    ifelse((d1=="a") & (d2 == "b"), 2,
+    ifelse((d1 == "e"), 3, 99)))
>     
> data.frame(d1, d2, w)
  d1 d2  w
1  e  e  1
2  c  a 99
3  a  b  2

If you do not feel comfortable with the ifelse function, you can also work with the if and else statements for such applications.

try this:

<script src="https://maps.googleapis.com/maps/api/js"></script>

it works for me... the point is, change HTTP to HTTPS

@BindView(R.id.checkbox_id) // if you are using Butterknife
CheckBox yourCheckBox;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.your_activity); 
    yourCheckBox = (CheckBox)findViewById(R.id.checkbox_id);// If your are not using Butterknife (the traditional way)

    yourCheckBox.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            yourObject.setYourProperty(yourCheckBox.isChecked()); //yourCheckBox.isChecked() is the method to know if the checkBox is checked
            Log.d(TAG, "onClick: yourCheckBox = " + yourObject.getYourProperty() );
        }
    });
}

Obviously you have to make your XML with the id of your checkbox :

<CheckBox
    android:id="@+id/checkbox_id"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Your label"
    />

So, the method to know if the check box is checked is : (CheckBox) yourCheckBox.isChecked() it returns true if the check box is checked.

In simple words, order() gives the locations of elements of increasing magnitude.

For example, order(c(10,20,30)) will give 1,2,3 and order(c(30,20,10)) will give 3,2,1.

I did it with this (change width, height, margin-top and margin-left accordingly):

.wrapper {
    width:960px;
    height:590px;
    position:absolute;
    top:50%;
    left:50%;
    margin-top:-295px;
    margin-left:-480px;
}

<div class="wrapper"> -- Content -- </div>

1) Add selected class to target element
2) Find all children of parent element excluding target element
3) Remove class from target element

 <div id = "outer">
            <div class="item" id="inner1">Div 1 </div>
            <div class="item" id="inner2">Div 2 </div>

function getSiblings(target) {

setserial with the -g option appears to do what you want and the C source is available at http://www.koders.com/c/fid39344DABD14604E70DF1B8FEA7D920A94AF78BF8.aspx.

In this particular example I think @Tagir is 100% correct get it into one filter and do the two checks. I wouldn't use Optional.ofNullable the Optional stuff is really for return types not to be doing logic... but really neither here nor there.

I wanted to point out that java.util.Objects has a nice method for this in a broad case, so you can do this:

cars.stream()
    .filter(Objects::nonNull)

Which will clear out your null objects. For anyone not familiar, that's the short-hand for the following:

cars.stream()
    .filter(car -> Objects.nonNull(car))

To partially answer the question at hand to return the list of car names that starts with "M":

cars.stream()
    .filter(car -> Objects.nonNull(car))
    .map(car -> car.getName())
    .filter(carName -> Objects.nonNull(carName))
    .filter(carName -> carName.startsWith("M"))
    .collect(Collectors.toList());

Once you get used to the shorthand lambdas you could also do this:

cars.stream()
    .filter(Objects::nonNull)
    .map(Car::getName)        // Assume the class name for car is Car
    .filter(Objects::nonNull)
    .filter(carName -> carName.startsWith("M"))
    .collect(Collectors.toList());

Unfortunately once you .map(Car::getName) you'll only be returning the list of names, not the cars. So less beautiful but fully answers the question:

cars.stream()
    .filter(car -> Objects.nonNull(car))
    .filter(car -> Objects.nonNull(car.getName()))
    .filter(car -> car.getName().startsWith("M"))
    .collect(Collectors.toList());

This works reliably for me. Cell borders and height added for effect and clarity:

<table>_x000D_
  <tr>_x000D_
    <td style="text-align:right; border: thin solid; height:50px">Some label:</td>_x000D_
    <td style="border: thin solid;">_x000D_
      <input type="checkbox" checked="checked" id="chk1" style="cursor:pointer; "><label for="chk1" style="margin-top:auto; margin-left:5px; margin-bottom:auto; cursor:pointer;">Check Me</label>_x000D_
    </td>_x000D_
  </tr>_x000D_
</table>

You should start with the Wikipedia Filename page. It has a decent-sized table (Comparison of filename limitations), listing the reserved characters for quite a lot of file systems.

It also has a plethora of other information about each file system, including reserved file names such as CON under MS-DOS. I mention that only because I was bitten by that once when I shortened an include file from const.h to con.h and spent half an hour figuring out why the compiler hung.

Turns out DOS ignored extensions for devices so that con.h was exactly the same as con, the input console (meaning, of course, the compiler was waiting for me to type in the header file before it would continue).

For this specific use-case using try..except..else is the cleanest solution, the else clause will be executed if no exception was raised.

NOTE: The else clause must follow all except clauses

for i in iterator:
    try:
        # Do something.
    except:
        # Handle exception
    else:
        # Continue doing something

The trigger is executed on the MySQL server, not on the PHP one (even if those are both on the same machine).

So, I would say this is not quite possible -- at least not simply.

Still, considering this entry from the MySQL FAQ on Triggers :

23.5.11: Can triggers call an external application through a UDF?

Yes. For example, a trigger could invoke the sys_exec() UDF available here: https://github.com/mysqludf/lib_mysqludf_sys#readme

So, there might be a way via an UDF function that would launch the php executable/script. Not that easy, but seems possible. ;-)

There should be an easier way to do this, but, depending on what you're trying to do, the best route might be to convert to a regular Python datetime object:

datetime64Obj = np.datetime64('2002-07-04T02:55:41-0700')
print datetime64Obj.astype(object).year
# 2002
print datetime64Obj.astype(object).day
# 4

Based on comments below, this seems to only work in Python 2.7.x and Python 3.6+

If the .project and .classpath are already committed, then they need to be removed from the index (but not the disk)

git rm --cached .project
git rm --cached .classpath

Then the .gitignore would work (and that file can be added and shared through clones).
For instance, this gitignore.io/api/eclipse file will then work, which does include:

# Eclipse Core      
.project

# JDT-specific (Eclipse Java Development Tools)     
.classpath

Note that you could use a "Template Directory" when cloning (make sure your users have an environment variable $GIT_TEMPLATE_DIR set to a shared folder accessible by all).
That template folder can contain an info/exclude file, with ignore rules that you want enforced for all repos, including the new ones (git init) that any user would use.

As commented by Abdollah

When you change the index, you need to commit the change and push it.
Then the file is removed from the repository. So the newbies cannot checkout the files .classpath and .project from the repo.

Oracle has put a prevention cookie on the download link to force you to agree to the terms even though the license agreement to use Java clearly states that merely by using Java you 'agree' to the license..

The method that Oracle wants is you to download it with an agreement. After that, this script cn be modified for your specific Linux

Since you are using the lower version of PS:

What you can do in your case is you first download the module in your local folder.

Then, there will be a .psm1 file under that folder for this module.

You just

import-Module "Path of the file.psm1"

Here is the link to download the Azure Module: Azure Powershell

This will do your work.

To plot just a selection of your columns you can select the columns of interest by passing a list to the subscript operator:

ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)

What you tried was df['V1','V2'] this will raise a KeyError as correctly no column exists with that label, although it looks funny at first you have to consider that your are passing a list hence the double square brackets [[]].

import matplotlib.pyplot as plt
ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)
ax.set_xlabel("Hour", fontsize=12)
ax.set_ylabel("V", fontsize=12)
plt.show()

another option is to define Scanner input = new Scanner(System.in); inside the try block, this will create a new object each time you need to re-enter the values.

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

Since there is no Exception class inside App\Services\PayUService so it's not being triggered. Alternatively, you can use a use statement at the top of your class like use Exception; and then you can use catch (Exception $e).

Try adding a pair of class attributes, say 'even' and 'odd', to alternating list elements, e.g.

<ul>
    <li class="even"><a href="link">Link 1</a></li>
    <li class="odd"><a href="link">Link 2</a></li>
    <li class="even"><a href="link">Link 3</a></li>
    <li class="odd"><a href="link">Link 4</a></li>
    <li class="even"><a href="link">Link 5</a></li>
</ul>

In a <style> section of the HTML page, or in a linked stylesheet, you would define those same classes, specifying your desired background colours:

li.even { background-color: red; }
li.odd { background-color: blue; }

You might want to use a template library as your needs evolve to provide you with greater flexibility and to cut down on the typing. Why type all those list elements by hand?

the solution to the typescript:

Step1:

npm install jquery

npm install --save-dev @types/jquery

step2: in Angular.json add:

"scripts": [
        "node_modules/jquery/dist/jquery.min.js",
      ]

or in index.html add:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>

step3: in *.component.ts where you want to use jquery

import * as $ from 'jquery';  // dont need "declare let $"

Then you can use jquery the same as javaScript. This way, VScode supports auto-suggestion by Typescript

You could do something like this:

create procedure test
as
BEGIN

    create table #ids
    (
        rn int,
        id int
    )

    insert into #ids (rn, id)
    select distinct row_number() over(order by id) as rn, id
    from table

    declare @id int
    declare @totalrows int = (select count(*) from #ids)
    declare @currentrow int = 0

    while @currentrow <  @totalrows  
    begin 
        set @id = (select id from #ids where rn = @currentrow)

        exec stored_proc @varName=@id, @otherVarName='test'

        set @currentrow = @currentrow +1
    end  

END

The simple version is 0x is a prefix denoting a hexadecimal number, source.

So the value you're computing is after the prefix, in this case 10.

But that is not the number 10. The most significant bit 1 denotes the hex value while 0 denotes the units.

So the simple math you would do is

0x10

1 * 16 + 0 = 16

Note - you use 16 because hex is base 16.

Another example:

0xF7

15 * 16 + 7 = 247

You can get a list of values by searching for a hex table. For instance in this chart notice F corresponds with 15.

I really dislike the hard coding of paths to get to regasm, when you install a new .Net or run on a machine with a different version, you need to ensure you find a version of regasm. Here's a solution to find the regasm.exe from the most current .Net installed regasm.

Within a bat file:

for /f %%a in ('dir %windir%\Microsoft.Net\Framework\regasm.exe /s /b') do set currentRegasm="%%a"
%currentRegasm% "full\path\to\your.dll" /options

Outside of a bat file (i.e. command prompt), just use %a instead of %%a

For me to make it work again I just deleted the files

ib_logfile0

and

MAMP:Version 4.3 (853)

To increase the heap size you can use the -Xmx argument when starting Java; e.g.

-Xmx256M

.box-author-txt {width:596px; float:left; padding:5px 0px 10px 10px;  border:1px #dddddd solid; -moz-border-radius: 0 0 5px 5px; -webkit-border-radius: 0 0 5px 5px; -o-border-radius: 0 0 5px 5px; border-radius: 0 0 5px 5px; overflow-x: scroll; white-space: nowrap; overflow-y: hidden;}


.box-author-txt ul{ vertical-align:top; height:auto; display: inline-block; white-space: nowrap; margin:0 9px 0 0; padding:0px;}
.box-author-txt ul li{ list-style-type:none;  width:140px; }

You have a certificate which is self-signed, so it's non-trusted by default, that's why OpenSSL complains. This warning is actually a good thing, because this scenario might also rise due to a man-in-the-middle attack.

To solve this, you'll need to install it as a trusted server. If it's signed by a non-trusted CA, you'll have to install that CA's certificate as well.

Have a look at this link about installing self-signed certificates.

Try this code

public static String pathRoot = "/sdcard/system/temp/";
public static String readFromFile(Context contect, String nameFile) {
    String aBuffer = "";
    try {
        File myFile = new File(pathRoot + nameFile);
        FileInputStream fIn = new FileInputStream(myFile);
        BufferedReader myReader = new BufferedReader(new InputStreamReader(fIn));
        String aDataRow = "";
        while ((aDataRow = myReader.readLine()) != null) {
            aBuffer += aDataRow;
        }
        myReader.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return aBuffer;
}

Like the other answers say, you can't remove an item from a collection you're iterating over. You can get around this by explicitly using an Iterator and removing the item there.

Iterator<Item> iter = list.iterator();
while(iter.hasNext()) {
  Item blah = iter.next();
  if(...) {
    iter.remove(); // Removes the 'current' item
  }
}

This answer is similar to Alexander Ukhov's answer, except that it uses touch events rather than click events. Those event allow the parent to display the proper pressed states (e.g., ripple effect). This answer is also in Kotlin instead of Java.

view.setOnTouchListener { view, motionEvent ->
    (view.parent as View).onTouchEvent(motionEvent)
}

You are not providing the correct address for the file. You need to provide an address such as C:/Users/xyz/Desktop/myfile.xml

Update

data.table v1.9.6+ now supports OP's original attempt and the following answer is no longer necessary.

You can use DT[order(-rank(x), y)].

   x y v
1: c 1 7
2: c 3 8
3: c 6 9
4: b 1 1
5: b 3 2
6: b 6 3
7: a 1 4
8: a 3 5
9: a 6 6

Use strpos():

if (strpos($string2, 'http') === 0) {
   // It starts with 'http'
}

Remember the three equals signs (===). It will not work properly if you only use two. This is because strpos() will return false if the needle cannot be found in the haystack.

Keep in mind that if you want to use the chrome inspect in Windows, besides enabling usb debugging on you mobile, you should also install the usb driver for Windows.

You can find the drivers you need from the list here:

Furthermore, you should use a newer version of Chrome mobile than the one in your Desktop.

It's possible. But it's viewable anyway.

You can make this tool for yourself:

const btn = document.querySelector('.btn');
btn.onclick = textRead;
const copy = document.querySelector('.copy');
copy.onclick = Copy;
const file = document.querySelector('.file');
file.type = 'file';
const pre = document.querySelector('.pre');

var pretxt = pre;

if (pre.innerHTML == "") {
    copy.hidden = true;
}

function textRead() {
    let file = document.querySelector('.file').files[0];
    let read = new FileReader();
    read.addEventListener('load', function(e) {
        let data = e.target.result;
        pre.textContent = data;
    });
    read.readAsDataURL(file);
    copy.hidden = false;
}

function Copy() {
    var text = pre;
    var selection = window.getSelection();
    var range = document.createRange();
    range.selectNodeContents(text);
    selection.addRange(range);
    document.execCommand('copy');
    selection.removeAllRanges();
}

<input class="file" />
<br>
<button class="btn">Read File</button>
<pre class="pre"></pre>
<button class="copy">Copy</button>

How to use this tool?

1. Create a JavaScript file.
2. Go in the tool and choose your JavaScript file.
3. Copy result.
4. Paste the result in Notepad.
5. Remove data:text/javascript;base64,.
6. Paste eval(atob('Notepad Text')) to your code and change Notepad Text to your Notepad text result.

How to view this hidden code?

1. Copy the hidden code and paste it in Notepad.
2. Copy a string that after eval and atob.
3. Paste data:text/javascript;base64,String and change String to your copied string.

Implementing interfaces with abstract base classes is much simpler in modern Python 3 and they serve a purpose as an interface contract for plug-in extensions.

Create the interface/abstract base class:

from abc import ABC, abstractmethod

class AccountingSystem(ABC):

    @abstractmethod
    def create_purchase_invoice(self, purchase):
        pass

    @abstractmethod
    def create_sale_invoice(self, sale):
        log.debug('Creating sale invoice', sale)

Create a normal subclass and override all abstract methods:

class GizmoAccountingSystem(AccountingSystem):

    def create_purchase_invoice(self, purchase):
        submit_to_gizmo_purchase_service(purchase)

    def create_sale_invoice(self, sale):
        super().create_sale_invoice(sale)
        submit_to_gizmo_sale_service(sale)

You can optionally have common implementation in the abstract methods as in create_sale_invoice(), calling it with super() explicitly in the subclass as above.

Instantiation of a subclass that does not implement all the abstract methods fails:

class IncompleteAccountingSystem(AccountingSystem):
    pass

>>> accounting = IncompleteAccountingSystem()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: Can't instantiate abstract class IncompleteAccountingSystem with abstract methods
create_purchase_invoice, create_sale_invoice

You can also have abstract properties, static and class methods by combining corresponding annotations with @abstractmethod.

Abstract base classes are great for implementing plugin-based systems. All imported subclasses of a class are accessible via __subclasses__(), so if you load all classes from a plugin directory with importlib.import_module() and if they subclass the base class, you have direct access to them via __subclasses__() and you can be sure that the interface contract is enforced for all of them during instantiation.

Here's the plugin loading implementation for the AccountingSystem example above:

...
from importlib import import_module

class AccountingSystem(ABC):

    ...
    _instance = None

    @classmethod
    def instance(cls):
        if not cls._instance:
            module_name = settings.ACCOUNTING_SYSTEM_MODULE_NAME
            import_module(module_name)
            subclasses = cls.__subclasses__()
            if len(subclasses) > 1:
                raise InvalidAccountingSystemError('More than one '
                        f'accounting module: {subclasses}')
            if not subclasses or module_name not in str(subclasses[0]):
                raise InvalidAccountingSystemError('Accounting module '
                        f'{module_name} does not exist or does not '
                        'subclass AccountingSystem')
            cls._instance = subclasses[0]()
        return cls._instance

Then you can access the accounting system plugin object through the AccountingSystem class:

>>> accountingsystem = AccountingSystem.instance()

(Inspired by this PyMOTW-3 post.)

Hide the file input. Create a new input to capture a click event and forward it to the hidden input:

<input type="button" id="loadFileXml" value="loadXml" onclick="document.getElementById('file').click();" />
<input type="file" style="display:none;" id="file" name="file"/>

When you push a new branch the first time use: >git push -u origin

After that, you can just type a shorter command: >git push

The first-time -u option created a persistent upstream tracking branch with your local branch.

Keep in mind that MySQL has a maximum row size limit

The internal representation of a MySQL table has a maximum row size limit of 65,535 bytes, not counting BLOB and TEXT types. BLOB and TEXT columns only contribute 9 to 12 bytes toward the row size limit because their contents are stored separately from the rest of the row. Read more about Limits on Table Column Count and Row Size.

Maximum size a single column can occupy, is different before and after MySQL 5.0.3

Values in VARCHAR columns are variable-length strings. The length can be specified as a value from 0 to 255 before MySQL 5.0.3, and 0 to 65,535 in 5.0.3 and later versions. The effective maximum length of a VARCHAR in MySQL 5.0.3 and later is subject to the maximum row size (65,535 bytes, which is shared among all columns) and the character set used.

However, note that the limit is lower if you use a multi-byte character set like utf8 or utf8mb4.

Use TEXT types inorder to overcome row size limit.

The four TEXT types are TINYTEXT, TEXT, MEDIUMTEXT, and LONGTEXT. These correspond to the four BLOB types and have the same maximum lengths and storage requirements.

.p12 and .pfx are both PKCS #12 files. Am I missing something?

Have you tried renaming the exported .pfx file to have a .p12 extension?

I had the same problem - i wanted to pass a parameter to another page by clicking a hyperlink and get the value to go to the next page (without using GET because the parameter is stored in the URL).

to those who don't understand why you would want to do this the answer is you dont want the user to see sensitive information or you dont want someone editing the GET.

well after scouring the internet it seemed it wasnt possible to make a normal hyperlink using the POST method.

And then i had a eureka moment!!!! why not just use CSS to make the submit button look like a normal hyperlink??? ...and put the value i want to pass in a hidden field

i tried it and it works. you can see an exaple here http://paulyouthed.com/test/css-button-that-looks-like-hyperlink.php

the basic code for the form is:

    <form enctype="multipart/form-data" action="page-to-pass-to.php" method="post">
                        <input type="hidden" name="post-variable-name" value="value-you-want-pass"/>
                        <input type="submit" name="whatever" value="text-to-display" id="hyperlink-style-button"/>
                </form>

the basic css is:

    #hyperlink-style-button{
      background:none;
      border:0;
      color:#666;
      text-decoration:underline;
    }

    #hyperlink-style-button:hover{
      background:none;
      border:0;
      color:#666;
      text-decoration:none;
      cursor:pointer;
      cursor:hand;
    }

Simple method to get resource ID:

public int getDrawableName(Context ctx,String str){
    return ctx.getResources().getIdentifier(str,"drawable",ctx.getPackageName());
}

you need just in scss varible

$input-btn-focus-width:       .05rem !default;

The same as @Nix with a small change to be strongly typed:

If you don't want to query for it just create an entity, and then delete it.

                Customer customer = new Customer () { Id = id };
                context.Customers.Attach(customer);
                context.Customers.DeleteObject(customer);
                context.SaveChanges();

The reason this doesn't work is that when you call String(md.digest(convertme)), you are telling Java to interpret a sequence of encrypted bytes as a String. What you want is to convert the bytes into hexadecimal characters.

The primary purpose is to avoid chained indexing and eliminate the SettingWithCopyWarning.

Here chained indexing is something like dfc['A'][0] = 111

The document said chained indexing should be avoided in Returning a view versus a copy. Here is a slightly modified example from that document:

In [1]: import pandas as pd

In [2]: dfc = pd.DataFrame({'A':['aaa','bbb','ccc'],'B':[1,2,3]})

In [3]: dfc
Out[3]:
    A   B
0   aaa 1
1   bbb 2
2   ccc 3

In [4]: aColumn = dfc['A']

In [5]: aColumn[0] = 111
SettingWithCopyWarning: 
A value is trying to be set on a copy of a slice from a DataFrame

In [6]: dfc
Out[6]:
    A   B
0   111 1
1   bbb 2
2   ccc 3

Here the aColumn is a view and not a copy from the original DataFrame, so modifying aColumn will cause the original dfc be modified too. Next, if we index the row first:

In [7]: zero_row = dfc.loc[0]

In [8]: zero_row['A'] = 222
SettingWithCopyWarning: 
A value is trying to be set on a copy of a slice from a DataFrame

In [9]: dfc
Out[9]:
    A   B
0   111 1
1   bbb 2
2   ccc 3

This time zero_row is a copy, so the original dfc is not modified.

From these two examples above, we see it's ambiguous whether or not you want to change the original DataFrame. This is especially dangerous if you write something like the following:

In [10]: dfc.loc[0]['A'] = 333
SettingWithCopyWarning: 
A value is trying to be set on a copy of a slice from a DataFrame

In [11]: dfc
Out[11]:
    A   B
0   111 1
1   bbb 2
2   ccc 3

This time it didn't work at all. Here we wanted to change dfc, but we actually modified an intermediate value dfc.loc[0] that is a copy and is discarded immediately. It’s very hard to predict whether the intermediate value like dfc.loc[0] or dfc['A'] is a view or a copy, so it's not guaranteed whether or not original DataFrame will be updated. That's why chained indexing should be avoided, and pandas generates the SettingWithCopyWarning for this kind of chained indexing update.

Now is the use of .copy(). To eliminate the warning, make a copy to express your intention explicitly:

In [12]: zero_row_copy = dfc.loc[0].copy()

In [13]: zero_row_copy['A'] = 444 # This time no warning

Since you are modifying a copy, you know the original dfc will never change and you are not expecting it to change. Your expectation matches the behavior, then the SettingWithCopyWarning disappears.

Note, If you do want to modify the original DataFrame, the document suggests you use loc:

In [14]: dfc.loc[0,'A'] = 555

In [15]: dfc
Out[15]:
    A   B
0   555 1
1   bbb 2
2   ccc 3

In windows XP and later, there's a command: tasklist that lists all process id's.

For killing a process in Windows, see:

You can execute OS-commands in Java by:

Runtime.getRuntime().exec("your command here");

If you need to handle the output of a command, see example: using Runtime.exec() in Java

It is possible.

<span ng-if="checked && checked2">
  I'm removed when the checkbox is unchecked.

The correct way to change directories is actually with process.chdir(directory). Here's an example from the documentation:

console.log('Starting directory: ' + process.cwd());
try {
  process.chdir('/tmp');
  console.log('New directory: ' + process.cwd());
}
catch (err) {
  console.log('chdir: ' + err);
}

This is also testable in the Node.js REPL:

[monitor@s2 ~]$ node
> process.cwd()
'/home/monitor'
> process.chdir('../');
undefined
> process.cwd();
'/home'

Keep a reference to the timer somewhere, and use:

timer.cancel();
timer.purge();

to stop whatever it's doing. You could put this code inside the task you're performing with a static int to count the number of times you've gone around, e.g.

private static int count = 0;
public static void run() {
     count++;
     if (count >= 6) {
         timer.cancel();
         timer.purge();
         return;
     }

     ... perform task here ....

}

Here's an answer http://wiki.python.org/moin/DictionaryKeys

What would go wrong if you tried to use lists as keys, with the hash as, say, their memory location?

Looking up different lists with the same contents would produce different results, even though comparing lists with the same contents would indicate them as equivalent.

What about Using a list literal in a dictionary lookup?

for all those linux users that are having this problem, check if the rxjs-compat folder is locked. I had this exact same issue and I went in terminal, used the sudo su to give permission to the whole rxjs-compat folder and it was fixed. Thats assuming you imported

import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch'; 

in the project.ts file where the original .map error occurred.

First set your path to C:/Program Files/Java/jdk1.8.0/bin in the environment variables. Say, your file is saved in the C: drive Now open the command prompt and move to the directory using c: javac Filename.java java Filename

Make sure you save the file name as .java.

If it is saved as a text file name then file not found error results as it cannot the text file.

if there are multiple java processes and you wish to kill them with one command try the below command

kill -9 $(ps -ef | pgrep -f "java")

replace "java" with any process string identifier , to kill anything else.

I used another solution (by @satprem rath) already present in this chain.

To find the min value of age in the dataframe:

df.agg(min("age")).show()

+--------+
|min(age)|
+--------+
|      29|
+--------+

edit: to add more context.

While the above method printed the result, I faced issues when assigning the result to a variable to reuse later.

Hence, to get only the int value assigned to a variable:

from pyspark.sql.functions import max, min  

maxValueA = df.agg(max("A")).collect()[0][0]
maxValueB = df.agg(max("B")).collect()[0][0]

No, using sessions does not necessarily violate RESTfulness. If you adhere to the REST precepts and constraints, then using sessions - to maintain state - will simply be superfluous. After all, RESTfulness requires that the server not maintain state.

DF[ ! ( ( DF$sub ==1 & DF$day==2) | ( DF$sub ==3 & DF$day==4) ) , ]   # note the ! (negation)

Or if sub is a factor as suggested by your use of quotes:

DF[ ! paste(sub,day,sep="_") %in% c("1_2", "3_4"), ]

Could also use subset:

subset(DF,  ! paste(sub,day,sep="_") %in% c("1_2", "3_4") )

(And I endorse the use of which in Dirk's answer when using "[" even though some claim it is not needed.)

The easiest way is:

• Find the drop-down box at the top of Visual Studio's window that says Debug
• Select Release
• Hit F6 to build it
• Switch back to Debug and then close Visual Studio
• Open Windows Explorer and navigate to your project's folder (My Documents\Visual Studio 200x\Projects\my_project\)
• Now go to bin\Release\ and copy the executable from there to wherever you want to store it
• Make shortcuts as appropriate and enjoy your new game! :)

Try this,

int dialogButton = JOptionPane.YES_NO_OPTION;
int dialogResult = JOptionPane.showConfirmDialog(this, "Your Message", "Title on Box", dialogButton);
if(dialogResult == 0) {
  System.out.println("Yes option");
} else {
  System.out.println("No Option");
} 

What about this;

 git commit --allow-empty-message -m ''

When you include Underscore, it attaches itself to the window object, and so is available globally.

So you can use it from Angular code as-is.

You can also wrap it up in a service or a factory, if you'd like it to be injected:

var underscore = angular.module('underscore', []);
underscore.factory('_', ['$window', function($window) {
  return $window._; // assumes underscore has already been loaded on the page
}]);

And then you can ask for the _ in your app's module:

// Declare it as a dependency of your module
var app = angular.module('app', ['underscore']);

// And then inject it where you need it
app.controller('Ctrl', function($scope, _) {
  // do stuff
});

By selecting 'Class Library' you were accidentally telling it to make a .Net Library using the CLI (managed) extenstion of C++.

Instead, create a Win32 project, and in the Application Settings on the next page, choose 'DLL'.

You can also make an MFC DLL or ATL DLL from those library choices if you want to go that route, but it sounds like you don't.

Here is working source code using a function approach.

<html>
    <head>
        <style>
            .news{padding:10px; margin-top:2px;background-color:red;color:#fff;}
        </style>
    </head>

    <body>
    <div id="dd"></div>
        <script>
            (function(){
                var countup = this;
                var newNode = document.createElement('div');
                newNode.className = 'textNode news content';
                newNode.innerHTML = 'this created div contains a class while created!!!';
                document.getElementById('dd').appendChild(newNode);
            })();
        </script>
    </body>
</html>

document.getElementById("select").selectedIndex = 0 will work

I have run into problems in the past with IE and the css:hover selector so the approach that I have taken, is to use a custom directive.

.directive('hoverClass', function () {
    return {
        restrict: 'A',
        scope: {
            hoverClass: '@'
        },
        link: function (scope, element) {
            element.on('mouseenter', function() {
                element.addClass(scope.hoverClass);
            });
            element.on('mouseleave', function() {
                element.removeClass(scope.hoverClass);
            });
        }
    };
})

then on the element itself you can add the directive with the class names that you want enabled when the mouse is over the the element for example:

<li data-ng-repeat="item in social" hover-class="hover tint" class="social-{{item.name}}" ng-mouseover="hoverItem(true);" ng-mouseout="hoverItem(false);"
                index="{{$index}}"><i class="{{item.icon}}"
                box="course-{{$index}}"></i></li>

This should add the class hover and tint when the mouse is over the element and doesn't run the risk of a scope variable name collision. I haven't tested but the mouseenter and mouseleave events should still bubble up to the containing element so in the given scenario the following should still work

<div hover-class="hover" data-courseoverview data-ng-repeat="course in courses | orderBy:sortOrder | filter:search"
 data-ng-controller ="CourseItemController"
 data-ng-class="{ selected: isSelected }">

providing of course that the li's are infact children of the parent div

1. rebuild project in VS
2. copy project folder to iis folder, probably C:\inetpub\wwwroot\
3. in iis manager (run>inetmgr) add website, point to folder, point application pool based on your .net
4. add web service to created website, almost the same as 3.
5. INSTALL ASP for windows 7 and .net 4.0: c:\windows\microsoft.net framework\v4.(some numbers)\regiis.exe -i
6. check access to web service on your browser

Alternatively, as long as permissions are not given, the good old <noscript> tags works. You can cover the page in css and tell them what's wrong, ... without using javascript ofcourse.

Yes. You could use the below code:

this.tagName

You can use select ... into ... to create and populate a temp table and then query the temp table to return the result.

select *
into #TempTable
from YourTable

select *
from #TempTable

a.txt

this is line 1
this is line 2

>>> file = open('a.txt').read()
>>> file
>>> file.split('\n')
['this is line 1', 'this is line 2', '']

I'm on Linux, but I guess you just use \r\n on Windows and it would also work

Note that you can use other tricks like :

-- One or more wildcard:
       .../Downloads20*/*.csv
--  braces and brackets   
       .../Downloads201[1-5]/book.csv
       .../Downloads201{11,15,19,99}/book.csv

A different approach that I found ugly compared to the classic dict+append, but that works:

df = df.T

df[0] = ['1/1/2013', 'Smith','test',123]

df = df.T

df
Out[6]: 
       Date   Name Action   ID
0  1/1/2013  Smith   test  123

If you don't want to use a module you have to install like requests, and your use case is very basic, then you can use urllib2

urllib2.urlopen(url, body)

See the documentation for urllib2 here: https://docs.python.org/2/library/urllib2.html.

While trying out the

pip install boto

command, I encounter the error

ImportError: No module named pkg_resources

To resolve this, issue another command to handle the setuptools using curl

curl https://bootstrap.pypa.io/ez_setup.py | python

After doing that, the following command will work perfectly.

pip install boto

Set JAVA_HOME in environment variable.

dplyr >= 1.0.0 using across

sum up each row using rowSums (rowwise works for any aggreation, but is slower)

df %>%
   replace(is.na(.), 0) %>%
   mutate(sum = rowSums(across(where(is.numeric))))

sum down each column

df %>%
   summarise(across(everything(), ~ sum(., is.na(.), 0)))

dplyr < 1.0.0

sum up each row

df %>%
   replace(is.na(.), 0) %>%
   mutate(sum = rowSums(.[1:5]))

sum down each column using superseeded summarise_all:

df %>%
   replace(is.na(.), 0) %>%
   summarise_all(funs(sum))

I had the same for problem for a while. Adding window.scrollTo(0, 0);to every page is painful and redundant. So i added a HOC which will wrap all my routes and it will stay inside BrowserRouter component:

 <ScrollTop>
    <Routes />
  </ScrollTop>

Inside ScrollTopComponent we have the following:

import React, { useEffect } from "react";
import { useLocation } from "react-router-dom";

const ScrollTop = (props) => {
  const { children } = props;

  const location = useLocation();

  useEffect(() => {
    window.scrollTo(0, 0);
  }, [location]);

  return <main>{children}</main>;
};

export default ScrollTop;

use tar to split into multiple archives

there are plenty of programs that will work with tar files on windows, including cygwin.

You need convert list to numpy array and then reshape:

df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)
   a  b  c
0  1  2  3
1  4  5  6
2  7  8  9

Just use JSON.stringify(object). It's built into Javascript and can therefore also be used within Typescript.

Avoid multipart forms in Richfaces:

<h:form enctype="multipart/form-data">
    <a4j:poll id="poll" interval="10000"/>
</h:form>

If you are using Richfaces, i have found that ajax requests inside of multipart forms return a new View ID on each request.

How to debug:

On each ajax request a View ID is returned, that is fine as long as the View ID is always the same. If you get a new View ID on each request, then there is a problem and must be fixed.

If you want to submit files using ajax use "jquery.form.js" This submits all form elements easily.

Samples http://jquery.malsup.com/form/#ajaxSubmit

rough view :

<form id='AddPhotoForm' method='post' action='../photo/admin_save_photo.php' enctype='multipart/form-data'>

<script type="text/javascript">
function showResponseAfterAddPhoto(responseText, statusText)
{ 
    information= responseText;
    callAjaxtolist();
    $("#AddPhotoForm").resetForm();
    $("#photo_msg").html('<div class="album_msg">Photo uploaded Successfully...</div>');        
};

$(document).ready(function(){
    $('.add_new_photo_div').live('click',function(){
            var options = {success:showResponseAfterAddPhoto};  
            $("#AddPhotoForm").ajaxSubmit(options);
        });
});
</script>

You may want to try the following:

SELECT  l.position, 
        l.username, 
        l.score,
        @curRow := @curRow + 1 AS row_number
FROM    league_girl l
JOIN    (SELECT @curRow := 0) r;

The JOIN (SELECT @curRow := 0) part allows the variable initialization without requiring a separate SET command.

Test case:

CREATE TABLE league_girl (position int, username varchar(10), score int);
INSERT INTO league_girl VALUES (1, 'a', 10);
INSERT INTO league_girl VALUES (2, 'b', 25);
INSERT INTO league_girl VALUES (3, 'c', 75);
INSERT INTO league_girl VALUES (4, 'd', 25);
INSERT INTO league_girl VALUES (5, 'e', 55);
INSERT INTO league_girl VALUES (6, 'f', 80);
INSERT INTO league_girl VALUES (7, 'g', 15);

Test query:

SELECT  l.position, 
        l.username, 
        l.score,
        @curRow := @curRow + 1 AS row_number
FROM    league_girl l
JOIN    (SELECT @curRow := 0) r
WHERE   l.score > 50;

Result:

+----------+----------+-------+------------+
| position | username | score | row_number |
+----------+----------+-------+------------+
|        3 | c        |    75 |          1 |
|        5 | e        |    55 |          2 |
|        6 | f        |    80 |          3 |

You cannot set cookies for another domain. Allowing this would present an enormous security flaw.

You need to get b.com to set the cookie. If a.com redirect the user to b.com/setcookie.php?c=value

The setcookie script could contain the following to set the cookie and redirect to the correct page on b.com

<?php
    setcookie('a', $_GET['c']);
    header("Location: b.com/landingpage.php");
?>

This problem might occur if you define 2 different schema's with same Collection name

I'm not sure about the syntax of your specific commands (e.g., vagrant, etc), but in general...

Just register Ansible's (not-normally-shown) JSON output to a variable, then display each variable's stdout_lines attribute:

- name: Generate SSH keys for vagrant user
  user: name=vagrant generate_ssh_key=yes ssh_key_bits=2048
  register: vagrant
- debug: var=vagrant.stdout_lines

- name: Show SSH public key
  command: /bin/cat $home_directory/.ssh/id_rsa.pub
  register: cat
- debug: var=cat.stdout_lines

- name: Wait for user to copy SSH public key
  pause: prompt="Please add the SSH public key above to your GitHub account"
  register: pause
- debug: var=pause.stdout_lines

I had been facing this problem for two days and I found that the directory you create in Oracle also needs to created first on your physical disk.

I didn't find this point mentioned anywhere i tried to look up the solution to this.

Example

If you created a directory, let's say, 'DB_DIR'.

CREATE OR REPLACE DIRECTORY DB_DIR AS 'E:\DB_WORKS';

Then you need to ensure that DB_WORKS exists in your E:\ drive and also file system level Read/Write permissions are available to the Oracle process.

My understanding of UTL_FILE from my experiences is given below for this kind of operation.

UTL_FILE is an object under SYS user. GRANT EXECUTE ON SYS.UTL_FILE TO PUBLIC; needs to given while logged in as SYS. Otherwise, it will give declaration error in procedure. Anyone can create a directory as shown:- CREATE OR REPLACE DIRECTORY DB_DIR AS 'E:\DBWORKS'; But CREATE DIRECTORY permission should be in place. This can be granted as shown:- GRANT CREATE ALL DIRECTORY TO user; while logged in as SYS user. However, if this needs to be used by another user, grants need to be given to that user otherwise it will throw error. GRANT READ, WRITE, EXECUTE ON DB_DIR TO user; while loggedin as the user who created the directory. Then, compile your package. Before executing the procedure, ensure that the Directory exists physically on your Disk. Otherwise it will throw 'Invalid File Operation' error. (V. IMPORTANT) Ensure that Filesystem level Read/Write permissions are in place for the Oracle process. This is separate from the DB level permissions granted.(V. IMPORTANT) Execute procedure. File should get populated with the result set of your query.

You can use getString

String name = jsonObject.getString("name");
// it will throws exception if the key you specify doesn't exist

or optString

String name = jsonObject.optString("name");
// it will returns the empty string ("") if the key you specify doesn't exist

What you are talking about is the preview image and text that Facebook extracts when you share a link. Facebook uses the Open Graph Protocol to get this data.

Essentially, all you'll have to do is place these og:meta tags on the URL that you want to share -

<meta property="og:title" content="The Rock"/>
<meta property="og:type" content="movie"/>
<meta property="og:url" content="http://www.imdb.com/title/tt0117500/"/>
<meta property="og:image" content="http://ia.media-imdb.com/rock.jpg"/>
<meta property="og:site_name" content="IMDb"/>
<meta property="fb:admins" content="USER_ID"/>
<meta property="og:description"
      content="A group of U.S. Marines, under command of
               a renegade general, take over Alcatraz and
               threaten San Francisco Bay with biological
               weapons."/>

As you can see there are both an image property and a description. When you make changes to your pages og:meta tags, you can test these changes using the Facebook Debugger. It will tell you if you have made any mistakes (and how to fix them!)

My suggestion would be to use RestSharp. You can make calls to REST services and have them cast into POCO objects with very little boilerplate code to actually have to parse through the response. This will not solve your particular error, but it answers your overall question of how to make calls to REST services. Having to change your code to use it should pay off in the ease of use and robustness moving forward. That is just my two cents though.

Example:

namespace RestSharpThingy
{
    using System;
    using System.Collections.Generic;
    using System.IO;
    using System.Linq;
    using System.Net;
    using System.Reflection;

    using RestSharp;

    {
        public static void Main()
        {
            Uri baseUrl = new Uri("https://httpbin.org/");
            IRestClient client = new RestClient(baseUrl);
            IRestRequest request = new RestRequest("get", Method.GET) { Credentials = new NetworkCredential("testUser", "P455w0rd") };

            request.AddHeader("Authorization", "Bearer qaPmk9Vw8o7r7UOiX-3b-8Z_6r3w0Iu2pecwJ3x7CngjPp2fN3c61Q_5VU3y0rc-vPpkTKuaOI2eRs3bMyA5ucKKzY1thMFoM0wjnReEYeMGyq3JfZ-OIko1if3NmIj79ZSpNotLL2734ts2jGBjw8-uUgKet7jQAaq-qf5aIDwzUo0bnGosEj_UkFxiJKXPPlF2L4iNJSlBqRYrhw08RK1SzB4tf18Airb80WVy1Kewx2NGq5zCC-SCzvJW-mlOtjIDBAQ5intqaRkwRaSyjJ_MagxJF_CLc4BNUYC3hC2ejQDoTE6HYMWMcg0mbyWghMFpOw3gqyfAGjr6LPJcIly__aJ5__iyt-BTkOnMpDAZLTjzx4qDHMPWeND-TlzKWXjVb5yMv5Q6Jg6UmETWbuxyTdvGTJFzanUg1HWzPr7gSs6GLEv9VDTMiC8a5sNcGyLcHBIJo8mErrZrIssHvbT8ZUPWtyJaujKvdgazqsrad9CO3iRsZWQJ3lpvdQwucCsyjoRVoj_mXYhz3JK3wfOjLff16Gy1NLbj4gmOhBBRb8rJnUXnP7rBHs00FAk59BIpKLIPIyMgYBApDCut8V55AgXtGs4MgFFiJKbuaKxq8cdMYEVBTzDJ-S1IR5d6eiTGusD5aFlUkAs9NV_nFw");
            request.AddParameter("clientId", 123);

            IRestResponse<RootObject> response = client.Execute<RootObject>(request);

            if (response.IsSuccessful)
            {

            }
            else

            Console.WriteLine();

            string path = Assembly.GetExecutingAssembly().Location;
            string name = Path.GetFileName(path);

Simply create an object of Base64 and use it to encode or decode, when using org.apache.commons.codec.binary.Base64 library

To Encode

Base64 ed=new Base64();

String encoded=new String(ed.encode("Hello".getBytes()));

Replace "Hello" with the text to be encoded in String Format.

To Decode

Base64 ed=new Base64();

String decoded=new String(ed.decode(encoded.getBytes()));

Here encoded is the String variable to be decoded

Add the following to Body tag,

<body onload="document.forms['member_signup'].submit()">

and give name attribute to your Form.

<form method="POST" action="" name="member_signup">

There is no way to get the memory address of a value in Python 2.7 in general. In Jython or PyPy, the implementation doesn't even know your value's address (and there's not even a guarantee that it will stay in the same place—e.g., the garbage collector is allowed to move it around if it wants).

However, if you only care about CPython, id is already returning the address. If the only issue is how to format that integer in a certain way… it's the same as formatting any integer:

>>> hex(33)
0x21
>>> '{:#010x}'.format(33) # 32-bit
0x00000021
>>> '{:#018x}'.format(33) # 64-bit
0x0000000000000021

… and so on.

However, there's almost never a good reason for this. If you actually need the address of an object, it's presumably to pass it to ctypes or similar, in which case you should use ctypes.addressof or similar.

int total = 0;
protected void gvEmp_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType==DataControlRowType.DataRow)
{
total += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "Amount"));
}
if(e.Row.RowType==DataControlRowType.Footer)
{
Label lblamount = (Label)e.Row.FindControl("lblTotal");
lblamount.Text = total.ToString();
}
}

ALTER TABLE `group` RENAME `member`

group is keyword so you must have to enclose into group

1. When you create an IIS application only the /bin or /App_Code folder is in the root directory of the IIS app. So just remember put all the code in the root /bin or /App_code directory (see http://blogs.msdn.com/b/chrsmith/archive/2006/08/10/wcf-service-nesting-in-iis.aspx).

2. Make sure that the service name and the contract contain full name(e.g namespace.ClassName), and the service name and interface is the same as the name attribute of the service tag and contract of endpoint in web.config.
