You can try https://rubygems.org/gems/dates_from_string:

Find date in structure:

text = "get car from repair 2015-02-02 23:00:10"
dates_from_string = DatesFromString.new
dates_from_string.find_date(text)

=> ["2015-02-02 23:00:10"]

curb looks like a great solution, but in case it doesn't meet your needs, you can do it with Net::HTTP. A multipart form post is just a carefully-formatted string with some extra headers. It seems like every Ruby programmer who needs to do multipart posts ends up writing their own little library for it, which makes me wonder why this functionality isn't built-in. Maybe it is... Anyway, for your reading pleasure, I'll go ahead and give my solution here. This code is based off of examples I found on a couple of blogs, but I regret that I can't find the links anymore. So I guess I just have to take all the credit for myself...

The module I wrote for this contains one public class, for generating the form data and headers out of a hash of String and File objects. So for example, if you wanted to post a form with a string parameter named "title" and a file parameter named "document", you would do the following:

#prepare the query
data, headers = Multipart::Post.prepare_query("title" => my_string, "document" => my_file)

Then you just do a normal POST with Net::HTTP:

http = Net::HTTP.new(upload_uri.host, upload_uri.port)
res = http.start {|con| con.post(upload_uri.path, data, headers) }

Or however else you want to do the POST. The point is that Multipart returns the data and headers that you need to send. And that's it! Simple, right? Here's the code for the Multipart module (you need the mime-types gem):

# Takes a hash of string and file parameters and returns a string of text
# formatted to be sent as a multipart form post.

The Python lxml library acts as a Pythonic binding for the libxml2 and libxslt libraries. I like particularly its XPath support and pretty-printing of the in-memory XML structure. It also supports parsing broken HTML. And I don't think you can find other Python libraries/bindings that parse XML faster than lxml.

I don't think adb pull handles wildcards for multiple files. I ran into the same problem and did this by moving the files to a folder and then pulling the folder.

I found a link doing the same thing. Try following these steps.

How to copy selected files from Android with adb pull

This works in all browsers:

window.location.href = '...';

If you wanted to change the page without it reflecting in the browser back history, you can do:

window.location.replace('...');

You need to combine multiple classes (col-*-offset-* for left-margin and col-*-pull-* to pull it right)

So you don't need to separate it manually into different rows.

If you create a user using a profile like this:

CREATE PROFILE my_profile LIMIT
       PASSWORD_LIFE_TIME 30;
ALTER USER scott PROFILE my_profile;

then you can change the password lifetime like this:

ALTER PROFILE my_profile LIMIT
  PASSWORD_LIFE_TIME UNLIMITED;

I hope that helps.

What you are passing to JSON.parse method must be a valid JSON after removing the wrapping quotes for string.

so something is not a valid JSON but "something" is.

A valid JSON is -

JSON = null
    /* boolean literal */
    or true or false
    /* A JavaScript Number Leading zeroes are prohibited; a decimal point must be followed by at least one digit.*/
    or JSONNumber
    /* Only a limited sets of characters may be escaped; certain control characters are prohibited; the Unicode line separator (U+2028) and paragraph separator (U+2029) characters are permitted; strings must be double-quoted.*/
    or JSONString

    /* Property names must be double-quoted strings; trailing commas are forbidden. */
    or JSONObject
    or JSONArray

Examples -

JSON.parse('{}'); // {}
JSON.parse('true'); // true
JSON.parse('"foo"'); // "foo"
JSON.parse('[1, 5, "false"]'); // [1, 5, "false"]
JSON.parse('null'); // null 
JSON.parse("'foo'"); // error since string should be wrapped by double quotes

You may want to look JSON.

The finishAffinity method, released in API 16, closes all ongoing activities and closes the app:

this.finishAffinity();

Finish this activity as well as all activities immediately below it in the current task that have the same affinity. This is typically used when an application can be launched on to another task (such as from an ACTION_VIEW of a content type it understands) and the user has used the up navigation to switch out of the current task and in to its own task. In this case, if the user has navigated down into any other activities of the second application, all of those should be removed from the original task as part of the task switch.

Note that this finish does not allow you to deliver results to the previous activity, and an exception will be thrown if you are trying to do so.

Since API 21, you can use:

finishAndRemoveTask();

Finishes all activities in this task and removes it from the recent tasks list.

Alternatives:

getActivity().finish();
System.exit(0);

int pid = android.os.Process.myPid();
android.os.Process.killProcess(pid);

Process.sendSignal(Process.myPid(), Process.SIGNAL_KILL);

Intent i = new Intent(context, LoginActivity.class);
i.putExtra(EXTRA_EXIT, true);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
context.startActivity(i);

Here's a simple code that reads strings from stdin, adds them into List<String>, and then uses toArray to convert it to String[] (if you really need to work with arrays).

import java.util.*;

public class UserInput {
    public static void main(String[] args) {
        List<String> list = new ArrayList<String>();
        Scanner stdin = new Scanner(System.in);

        do {
            System.out.println("Current list is " + list);
            System.out.println("Add more? (y/n)");
            if (stdin.next().startsWith("y")) {
                System.out.println("Enter : ");
                list.add(stdin.next());
            } else {
                break;
            }
        } while (true);
        stdin.close();
        System.out.println("List is " + list);
        String[] arr = list.toArray(new String[0]);
        System.out.println("Array is " + Arrays.toString(arr));
    }
}

I know its old question, anyway another exact explanation about $this. $this is mainly used to refer properties of a class.

Example:

Class A
{
   public $myname;    //this is a member variable of this class

function callme() {
    $myname = 'function variable';
    $this->myname = 'Member variable';
    echo $myname;                  //prints function variable
    echo $this->myname;              //prints member variable
   }
}

output:

function variable

member variable

If the project is Maven, you can try this way :

1. right click the "Maven Dependencies"-->"Build Path"-->"Remove from the build path";
2. right click the project ,navigate to "Maven"--->"Update project....";

Then the import issue should be solved .

A simple answer to the question can be given using these points:

1. Arrays are to be used when a collection of similar type data elements is required. Whereas, linked list is a collection of mixed type data linked elements known as nodes.

2. In array, one can visit any element in O(1) time. Whereas, in linked list we would need to traverse entire linked list from head to the required node taking O(n) time.

3. For arrays, a specific size needs to be declared initially. But linked lists are dynamic in size.

the easiest way I found is

for i in `ls`; do echo "`pwd`/$i"; done

it works well for me

None of these answers are reliable, and mine wont be much more reliable.

Caveats aside, if you do get into the lucky scenario where the element you're trying to have clicked doesn't have padding (such that all of the "inner" space of the element is completely covered by sub-elements), then you can check the target of the click event against the container itself. If it matches, that means you've clicked a :before or :after element.

Obviously this would not be feasible with both types (before and after) however I have implemented it as a hack/speed fix and it is working very well, without a bunch of position checking, which may be inaccurate depending on about a million different factors.

EDIT: Per comments below, this is not a solution. Not sure how I had it working, and can't check that project.

It's time to update this answer for the latest XAML.

Finding this SO question searching for a solution to this question, I then found that the updated XAML spec has a simple solution.

An attribute called "Placeholder" is now available to accomplish this task. It is as simple as this (in Visual Studio 2015):

<ComboBox x:Name="Selection" PlaceholderText="Select...">
    <x:String>Item 1</x:String>
    <x:String>Item 2</x:String>
    <x:String>Item 3</x:String>
</ComboBox>

If you are sure you want to remove all commit history, simply delete the .git directory in your project root (note that it's hidden). Then initialize a new repository in the same folder and link it to the GitHub repository:

git init
git remote add origin [email protected]:user/repo

now commit your current version of code

git add *
git commit -am 'message'

and finally force the update to GitHub:

git push -f origin master

However, I suggest backing up the history (the .git folder in the repository) before taking these steps!

Try this:

Send data and request with http header in page B to redirect to Gateway

<?php
$host = "www.example.com";
$path = "/path/to/script.php";
$data = "data1=value1&data2=value2";
$data = urlencode($data);

header("POST $path HTTP/1.1\\r\
" );
header("Host: $host\\r\
" );
header("Content-type: application/x-www-form-urlencoded\\r\
" );
header("Content-length: " . strlen($data) . "\\r\
" );
header("Connection: close\\r\
\\r\
" );
header($data);
?>

Additional Headers :

Accept: \*/\*
User-Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like 
Gecko) Chrome/74.0.3729.169 Safari/537.36

The best way is to use display:

inline-block; 

and

overflow: hidden;

This typically stems from a bug in revision control system, or similar. This was a product from CVS, if a file was checked in from Windows to Unix server, and then checked out again...

In other words, it is just broken...

Using the Apache Commons IO library...

boolean isFileUnlocked = false;
try {
    org.apache.commons.io.FileUtils.touch(yourFile);
    isFileUnlocked = true;
} catch (IOException e) {
    isFileUnlocked = false;
}

if(isFileUnlocked){
    // Do stuff you need to do with a file that is NOT locked.
} else {
    // Do stuff you need to do with a file that IS locked
}

In your AndroidManifest.xml file

<application
        android:name="ApplicationClass"
        android:icon="@drawable/ic_launcher"  <--------
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

In pyspark DOCS it would be subtract

df1.subtract(df2)

You actually don't need jQuery, just CSS. For example, here's some HTML:

<div class="special"></div>

And here's the CSS:

.special
{
    cursor: pointer;
}

You're on the right track. You may read the user input into an integer and switch on that:

enum Choice
{
  EASY = 1, 
  MEDIUM = 2, 
  HARD = 3
};

int i = -1;

// ...<present the user with a menu>...

cin >> i;

switch(i)
{
  case EASY:
    cout << "Easy\n";
    break;
  case MEDIUM:
    cout << "Medium\n";
    break;
  case HARD:
    cout << "Hard\n";
    break;
  default:
    cout << "Invalid Selection\n";
    break;
}

This is a PDO-only visualization, as the mysql_* library is deprecated.

<?php
    // Begin Vault (this is in a vault, not actually hard-coded)
    $host="hostname";
    $username="GuySmiley";
    $password="thePassword";
    $dbname="dbname";
    $port="3306";
    // End Vault

    try {
        $dbh = new PDO("mysql:host=$host;port=$port;dbname=$dbname;charset=utf8", $username, $password);
        $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        echo "I am connected.<br/>";

        // ... continue with your code

        // PDO closes connection at end of script
    } catch (PDOException $e) {
        echo 'PDO Exception: ' . $e->getMessage();
        exit();
    }
?>

Note that this OP Question appeared not to be about port numbers afterall. If you are using the default port of 3306 always, then consider removing it from the uri, that is, remove the port=$port; part.

If you often change ports, consider the above port usage for more maintainability having changes made to the $port variable.

Some likely errors returned from above:

PDO Exception: SQLSTATE[HY000] [2002] No connection could be made because the target machine actively refused it.
PDO Exception: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: No such host is known.

In the below error, we are at least getting closer, after changing our connect information:

PDO Exception: SQLSTATE[HY000] [1045] Access denied for user 'GuySmiley'@'localhost' (using password: YES)

After further changes, we are really close now, but not quite:

PDO Exception: SQLSTATE[HY000] [1049] Unknown database 'mustard'

From the Manual on PDO Connections:

I would suggest the following simple approach for conversion:

from datetime import datetime, timedelta
s = "20120213"
# you could also import date instead of datetime and use that.
date = datetime(year=int(s[0:4]), month=int(s[4:6]), day=int(s[6:8]))

For adding/subtracting an arbitary amount of days (seconds work too btw.), you could do the following:

date += timedelta(days=10)
date -= timedelta(days=5)

And convert back using:

s = date.strftime("%Y%m%d")

To convert the integer to a string safely, use:

s = "{0:-08d}".format(i)

This ensures that your string is eight charecters long and left-padded with zeroes, even if the year is smaller than 1000 (negative years could become funny though).

Further reference: datetime objects, timedelta objects

sleep infinity does exactly what it suggests and works without cat abuse.

To print nth line using sed with a variable as line number:

a=4
sed -e $a'q:d' file

Here the '-e' flag is for adding script to command to be executed.

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|00D900",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(12, 18)
);

void 0 returns undefined and can not be overwritten while undefined can be overwritten.

var undefined = "HAHA";

Simple Way to change the seek bar color ...

 <ProgressBar
            android:id="@+id/progress"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:theme="@style/Progress_color"/>

Style : Progress_color

 <style name="Progress_color">
    <item name="colorAccent">@color/white</item> <!-- Whatever color you want-->
</style>

java class change ProgressDrawable()

seek_bar.getProgressDrawable().setColorFilter(getResources().getColor(R.color.white), PorterDuff.Mode.MULTIPLY);

In SQL Server Management Studio, turn on SQLCMD mode from the Query menu. Then at the top of your script, type in the command below

:Connect server_name[\instance_name] [-l timeout] [-U user_name [-P password]

If you are connecting to multiple servers, be sure to insert GO between connections; otherwise your T-SQL won't execute on the server you're thinking it will.

For arbitrary levels of nestedness:

In [2]: def nested_dict():
   ...:     return collections.defaultdict(nested_dict)
   ...:

In [3]: a = nested_dict()

In [4]: a
Out[4]: defaultdict(<function __main__.nested_dict>, {})

In [5]: a['a']['b']['c'] = 1

In [6]: a
Out[6]:
defaultdict(<function __main__.nested_dict>,
            {'a': defaultdict(<function __main__.nested_dict>,
                         {'b': defaultdict(<function __main__.nested_dict>,
                                      {'c': 1})})})

This link was helpful . It contains the javascript code to detect all versions of IE up to IE11. I tested the script with IE11 emulator. To find the IE11 emulator, right-click on the web browser click "Inspect element". At the bottom-left of the page, scroll down the navigation bar and click the desktop icon. The "User Agent String" dropdown box contains options to emulate IE6-11.

It works. I just used it some minutes before writing this answer. Cannot post snapshots - not enough reputation.

From the v3 documentation (Developer's Guide > Concepts > Developing for Mobile Devices):

Android and iOS devices respect the following <meta> tag:

<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />

This setting specifies that the map should be displayed full-screen and should not be resizable by the user. Note that the iPhone's Safari browser requires this <meta> tag be included within the page's <head> element.

Note: This answer is for the specific question asked above. If you are here from Google and just looking for a way to get a Cartesian product in Python, itertools.product or a simple list comprehension may be what you are looking for - see the other answers.

Suppose len(list1) >= len(list2). Then what you appear to want is to take all permutations of length len(list2) from list1 and match them with items from list2. In python:

import itertools
list1=['a','b','c']
list2=[1,2]

[list(zip(x,list2)) for x in itertools.permutations(list1,len(list2))]

Returns

[[('a', 1), ('b', 2)], [('a', 1), ('c', 2)], [('b', 1), ('a', 2)], [('b', 1), ('c', 2)], [('c', 1), ('a', 2)], [('c', 1), ('b', 2)]]

I too got the same problem
I downloaded get-pip.py from https://bootstrap.pypa.io/get-pip.py

and then ran python2.7 get-pip.py for installing pip2.7

and then ran the pip install command with python2.7 as follows

For Ubuntu/Linux:

python2.7 -m pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl

For Mac OS X:

python2.7 -m pip install https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whl

this should work just fine as it did for me :)

I followed these instructions from here

On Postgres 10:

SELECT to_timestamp(CAST(epoch_ms as bigint)/1000)

I tend to use subprocess together with shlex (to handle escaping of quoted strings):

>>> import subprocess, shlex
>>> command = 'ls -l "/your/path/with spaces/"'
>>> call_params = shlex.split(command)
>>> print call_params
["ls", "-l", "/your/path/with spaces/"]
>>> subprocess.call(call_params)

Your problem arises from the fact that $i has a blank value when your statement fails. Always quote your variables when performing comparisons if there is the slightest chance that one of them may be empty, e.g.:

if [ "$i" -ge 2 ] ; then
  ...
fi

This is because of how the shell treats variables. Assume the original example,

if [ $i -ge 2 ] ; then ...

The first thing that the shell does when executing that particular line of code is substitute the value of $i, just like your favorite editor's search & replace function would. So assume that $i is empty or, even more illustrative, assume that $i is a bunch of spaces! The shell will replace $i as follows:

if [     -ge 2 ] ; then ...

Now that variable substitutions are done, the shell proceeds with the comparison and.... fails because it cannot see anything intelligible to the left of -gt. However, quoting $i:

if [ "$i" -ge 2 ] ; then ...

becomes:

if [ "    " -ge 2 ] ; then ...

The shell now sees the double-quotes, and knows that you are actually comparing four blanks to 2 and will skip the if.

You also have the option of specifying a default value for $i if $i is blank, as follows:

if [ "${i:-0}" -ge 2 ] ; then ...

This will substitute the value 0 instead of $i is $i is undefined. I still maintain the quotes because, again, if $i is a bunch of blanks then it does not count as undefined, it will not be replaced with 0, and you will run into the problem once again.

Please read this when you have the time. The shell is treated like a black box by many, but it operates with very few and very simple rules - once you are aware of what those rules are (one of them being how variables work in the shell, as explained above) the shell will have no more secrets for you.

To my knowledge the file has to be right in the folder where the 'this' class resides, i.e. not in WEB-INF/classes but nested even deeper (unless you write in a default package):

net/domain/pkg1/MyClass.java  
net/domain/pkg1/abc.txt

Putting the file in to your java sources should work, compiler copies that file together with class files.

There is no simple command available to find out the largest files/directories on a Linux/UNIX/BSD filesystem. However, combination of following three commands (using pipes) you can easily find out list of largest files:

# du -a /var | sort -n -r | head -n 10

If you want more human readable output try:

$ cd /path/to/some/var
$ du -hsx * | sort -rh | head -10

Where,

• Var is the directory you wan to search
• du command -h option : display sizes in human readable format (e.g., 1K, 234M, 2G).
• du command -s option : show only a total for each argument (summary).
• du command -x option : skip directories on different file systems.
• sort command -r option : reverse the result of comparisons.
• sort command -h option : compare human readable numbers. This is GNU sort specific option only.
• head command -10 OR -n 10 option : show the first 10 lines.

create a textbox:

 <TextBox Name="tb">
 ..hello..
</TextBox>

focus() ---> it is used to set input focus to the textbox control

tb.focus()

Another working example, using similar approach posted : create a html form, use javascript to simulate the post. This does 2 things : post data to a new page and open it in a new window/tab.

HTML

<form name='myForm' target="_blank" action='newpage.html' method='post'>
<input type="hidden" name="thisIsTheParameterName" value="testDataToBePosted"/>
</form>

JavaScript

document.forms["myForm"].submit();

I believe you can also do:

$sortDirection = 'desc';

$user->with(['comments' => function ($query) use ($sortDirection) {
    $query->orderBy('column', $sortDirection);
}]);

That allows you to run arbitrary logic on each related comment record. You could have stuff in there like:

$query->where('timestamp', '<', $someTime)->orderBy('timestamp', $sortDirection);

You're missing the necessary class definition; typically caused by required JAR not being in classpath.

From J2SE API:

public class NoClassDefFoundError extends LinkageError

Thrown if the Java Virtual Machine or a ClassLoader instance tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using the new expression) and no definition of the class could be found.

The searched-for class definition existed when the currently executing class was compiled, but the definition can no longer be found.

If you go the INSERT VALUES route to insert multiple rows, make sure to delimit the VALUES into sets using parentheses, so:

INSERT INTO `receiving_table`

  first_name,
  last_name)

  (1003,'George', 'Boole'),
  (1001,'Donald','Chamberlin'),

You need to pass in a sequence, but you forgot the comma to make your parameters a tuple:

cursor.execute('INSERT INTO images VALUES(?)', (img,))

Without the comma, (img) is just a grouped expression, not a tuple, and thus the img string is treated as the input sequence. If that string is 74 characters long, then Python sees that as 74 separate bind values, each one character long.

>>> len(img)
74
>>> len((img,))
1

If you find it easier to read, you can also use a list literal:

cursor.execute('INSERT INTO images VALUES(?)', [img])

Here's the simplest solution I have come across. I have learnt this from Beginning iOS 5 Development book.

Assuming the number field is called numberField.

1. In ViewController, add the following method:

   -(IBAction)closeKeyboard:(id)sender;
   

2. In ViewController.m, add the following code:

   -(IBAction)closeKeyboard:(id)sender
   {
   
        [numberField resignFirstResponder];
   
   }
   

3. Go back to nib file.

4. Open Utilities pan.
5. Open the Identity inspector under Utilities pan.
6. Click on the View (in nib file) once. Make sure you have not clicked on any of the items in the view. For the sake of clarification, you should see UIView under Class in Identity inspector.
7. Change the class from UIView to UIControl.
8. Open Connection Inspector.
9. Click and drag Touch Down and drop the arrow on File Owner icon. (FYI... File Owner icon is displayed on the left of View and appears as a hollow cube with yellow frame.)
10. Select the method: closeKeyboard.
11. Run the program.

Now when you click anywhere on background of View, you should be able to dismiss the keyboard.

Hope this helps you solve your problem. :-)

CharSequence = interface
String = concrete implementation

• CharSequence is an interface.
• Several classes implement this interface.
  • String is one such class, a concrete implementation of CharSequence.

You said:

converting from one to another

There is no converting from String.

• Every String object is a CharSequence.
• Every CharSequence can produce a String. Call CharSequence::toString. If the CharSequence happens to be a String, then the method returns a reference to its own object.

In other words, every String is a CharSequence, but not every CharSequence is a String.

Programming to an interface

Programming in Android, most of the text values are expected in CharSequence.

Why is that? What is the benefit, and what are the main impacts of using CharSequence over String?

Generally, programming to an interface is better than programming to concrete classes. This yields flexibility, so we can switch between concrete implementations of a particular interface without breaking other code.

When developing an API to be used by various programmers in various situations, write your code to give and take the most general interfaces possible. This gives the calling programmer the freedom to use various implementations of that interface, whichever implementation is best for their particular context.

For example, look at the Java Collections Framework. If your API gives or takes an ordered collection of objects, declare your methods as using List rather than ArrayList, LinkedList, or any other 3rd-party implementation of List.

When writing a quick-and-dirty little method to be used only by your code in one specific place, as opposed to writing an API to be used in multiple places, you need not bother with using the more general interface rather than a specific concrete class. But even then, it does to hurt to use the most general interface you can.

What are the main differences, and what issues are expected, while using them,

• With a String you know you have a single piece of text, entirely in memory, and is immutable.
• With a CharSequence, you do not know what the particular features of the concrete implementation might be.

The CharSequence object might represent an enormous chunk of text, and therefore has memory implications. Or may be many chunks of text tracked separately that will need to be stitched together when you call toString, and therefore has performance issues. The implementation may even be retrieving text from a remote service, and therefore has latency implications.

and converting from one to another?

You generally won't be converting back and forth. A String is a CharSequence. If your method declares that it takes a CharSequence, the calling programmer may pass a String object, or may pass something else such as a StringBuffer or StringBuilder. Your method's code will simply use whatever is passed, calling any of the CharSequence methods.

The closest you would get to converting is if your code receives a CharSequence and you know you need a String. Perhaps your are interfacing with old code written to String class rather than written to the CharSequence interface. Or perhaps your code will work intensively with the text, such as looping repeatedly or otherwise analyzing. In that case, you want to take any possible performance hit only once, so you call toString up front. Then proceed with your work using what you know to be a single piece of text entirely in memory.

Twisted history

Note the comments made on the accepted Answer. The CharSequence interface was retrofitted onto existing class structures, so there are some important subtleties (equals() & hashCode()). Notice the various versions of Java (1, 2, 4 & 5) tagged on the classes/interfaces—quite a bit of churn over the years. Ideally CharSequence would have been in place from the beginning, but such is life.

My class diagram below may help you see the big picture of string types in Java 7/8. I'm not sure if all of these are present in Android, but the overall context may still prove useful to you.

In my (linux mint) system I can not get working combination alt+insert so I do the next steps:

alt+1 (navigate to "tree") --> "context button - analog right mouse click" (between right alt and ctrl) -- then with arrows (up or down) desired choice (create new class or package or ...)

Hope it helps some "mint" owners )).

The abstract version can be:

import numpy as np
myList = [10, 20, 30, 40, 50, 60, 70, 80, 90]
myInt = 10
newList  = np.divide(myList, myInt)

I've setup xampp for my localhost as well, I've not done anything with the files created by xampp during or after setup.

But in the '.htaccess' file, make sure you've set it to something like this. Works for me, and this should not make any difference for you.

RewriteEngine On
RewriteRule ^filename/?$ filename.html

Change .html to whatever format you're using.

Make sure your install is clean, and just make the .htaccess file. Also remember to put one .htaccess file for each directory (don't really know if you can use ONE file for all folders, but to be safe, just do this and it will always work.

I tried the recommended solution that uses Application.ActivityLifecycleCallbacks and many others, but they didn't work as expected. Thanks to Sarge, I came up with a pretty easy and straightforward solution that I am describing below.

They key of the solution is the fact of understanding that if we have ActivityA and ActivityB, and we call ActivityB from ActivityA (and not call ActivityA.finish), then ActivityB's onStart() will be called before ActivityA onStop().

That's also the main difference between onStop() and onPause() that none did mention in the articles I read.

So based on this Activity's Lifecycle behavior, you can simply count how many times did onStart() and onPause() got called in your program. Note that for each Activity of your program, you must override onStart() and onStop(), in order to increment/decrement the static variable used for counting. Below is the code implementing this logic. Note that I am using a class that extends Application, so dont forget to declare on Manifest.xml inside Application tag: android:name=".Utilities", although it can be implemented using a simple custom class too.

public class Utilities extends Application
{
    private static int stateCounter;

    public void onCreate()
    {
        super.onCreate();
        stateCounter = 0;
    }

    /**
     * @return true if application is on background
     * */
    public static boolean isApplicationOnBackground()
    {
        return stateCounter == 0;
    }

    //to be called on each Activity onStart()
    public static void activityStarted()
    {
        stateCounter++;
    }

    //to be called on each Activity onStop()
    public static void activityStopped()
    {
        stateCounter--;
    }
}

Now on each Activity of our program, we should override onStart() and onStop() and increment/decrement as shown below:

@Override
public void onStart()
{
    super.onStart();
    Utilities.activityStarted();
}

@Override
public void onStop()
{
    Utilities.activityStopped();
    if(Utilities.isApplicationOnBackground())
    {
        //you should want to check here if your application is on background
    }
    super.onStop();
}

With this logic, there are 2 possible cases:

1. stateCounter = 0 : The number of stopped is equal with the number of started Activities, which means that the application is running on the background.
2. stateCounter > 0 : The number of started is bigger than the number of stopped, which means that the application is running on the foreground.

Notice: stateCounter < 0 would mean that there are more stopped Activities rather than started, which is impossible. If you encounter this case, then it means that you are not increasing/decreasing the counter as you should.

You are ready to go. You should want to check if your application is on background inside onStop().

If you want to match the two words in either order, use:

gci C:\Logs| select-string -pattern '(VendorEnquiry.*Failed)|(Failed.*VendorEnquiry)'

Of cause it's possible to create dynamic classes using very cool ExpandoObject class. But recently I worked on project and faced that Expando Object is serealized in not the same format on xml as an simple Anonymous class, it was pity =( , that is why I decided to create my own class and share it with you. It's using reflection and dynamic directive , builds Assembly, Class and Instance truly dynamicly. You can add, remove and change properties that is included in your class on fly Here it is :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Reflection.Emit;
using static YourNamespace.DynamicTypeBuilderTest;

namespace YourNamespace
{

    /// This class builds Dynamic Anonymous Classes

    public class DynamicTypeBuilderTest
    {    
        ///   
        /// Create instance based on any Source class as example based on PersonalData
        ///
        public static object CreateAnonymousDynamicInstance(PersonalData personalData, Type dynamicType, List<ClassDescriptorKeyValue> classDescriptionList)
        {
            var obj = Activator.CreateInstance(dynamicType);

            var propInfos = dynamicType.GetProperties();

            classDescriptionList.ForEach(x => SetValueToProperty(obj, propInfos, personalData, x));

            return obj;
        }

        private static void SetValueToProperty(object obj, PropertyInfo[] propInfos, PersonalData aisMessage, ClassDescriptorKeyValue description)
        {
            propInfos.SingleOrDefault(x => x.Name == description.Name)?.SetValue(obj, description.ValueGetter(aisMessage), null);
        }

        public static dynamic CreateAnonymousDynamicType(string entityName, List<ClassDescriptorKeyValue> classDescriptionList)
        {
            AssemblyName asmName = new AssemblyName();
            asmName.Name = $"{entityName}Assembly";
            AssemblyBuilder assemblyBuilder = AssemblyBuilder.DefineDynamicAssembly(asmName, AssemblyBuilderAccess.RunAndCollect);

            ModuleBuilder moduleBuilder = assemblyBuilder.DefineDynamicModule($"{asmName.Name}Module");

            TypeBuilder typeBuilder = moduleBuilder.DefineType($"{entityName}Dynamic", TypeAttributes.Public);

            classDescriptionList.ForEach(x => CreateDynamicProperty(typeBuilder, x));

            return typeBuilder.CreateTypeInfo().AsType();
        }

        private static void CreateDynamicProperty(TypeBuilder typeBuilder, ClassDescriptorKeyValue description)
        {
            CreateDynamicProperty(typeBuilder, description.Name, description.Type);
        }

        ///

        public static void CreateDynamicProperty(TypeBuilder typeBuilder, string name, Type propType)
        {
            FieldBuilder fieldBuider = typeBuilder.DefineField($"{name.ToLower()}Field",
                                                            propType,
                                                            FieldAttributes.Private);

                                                             propType,
                                                             null);

            MethodAttributes getSetAttr =
                MethodAttributes.Public | MethodAttributes.SpecialName |

            MethodBuilder methodGetBuilder =

            yield return new ClassDescriptorKeyValue("IsChild", typeof(bool), x => x.Age < 21);

            if (includeAddress)
                yield return new ClassDescriptorKeyValue("Address", typeof(string), x => x?.Contacts["Address"]);
            if (includeFacebook)
                yield return new ClassDescriptorKeyValue("Facebook", typeof(string), x => x?.Contacts["Facebook"]);
        }

        ///
        ///Source Data Class for example
        /// of cause you can use any other class
        public class PersonalData
        { 
            public int Id { get; set; }
            public string FirstName { get; set; }
            public string LastName { get; set; }
            public string Country { get; set; }
            public int Age { get; set; }

            public Dictionary<string, string> Contacts { get; set; }
        }

    }
}

It is also very simple to use DynamicTypeBuilder, you just need put few lines like this:

    public class ExampleOfUse
    {
        private readonly bool includeAddress;
        private readonly bool includeFacebook;
        private readonly dynamic dynamicType;
        private readonly List<ClassDescriptorKeyValue> classDiscriptionList;
        public ExampleOfUse(bool includeAddress = false, bool includeFacebook = false)
        {
            this.includeAddress = includeAddress;
            this.includeFacebook = includeFacebook;
            this.classDiscriptionList = DynamicTypeBuilderTest.GetAnonymousClassDescription(includeAddress, includeFacebook).ToList();
            this.dynamicType = DynamicTypeBuilderTest.CreateAnonymousDynamicType("VeryPrivateData", this.classDiscriptionList);
        }

        public object Map(PersonalData privateInfo)
        {
            object dynamicObject = DynamicTypeBuilderTest.CreateAnonymousDynamicInstance(privateInfo, this.dynamicType, classDiscriptionList);

            return dynamicObject;
        }

    }

I hope that this code snippet help somebody =) Enjoy!

One extra feature is you can also use-media queries in the media attribute of the <link> tag.

<link href="style.css" rel="stylesheet">
<link href="justForFrint.css" rel="stylesheet" media="print">
<link href="deviceSizeDepending.css" rel="stylesheet" media="(min-width: 40em)">

With this, the browser will download all CSS resources, regardless of the media attribute. The difference is that if the media-query of the media attribute is evaluated to false then that .css file and his content will not be render-blocking.

Therefore, it is recommended to use the media attribute in the <link> tag since it guarantees a better user experience.

Here you can read a Google article about this issue https://developers.google.com/web/fundamentals/performance/critical-rendering-path/render-blocking-css

Some tools that will help you to automate the separation of your css code in different files according to your media-querys

Webpack https://www.npmjs.com/package/media-query-plugin https://www.npmjs.com/package/media-query-splitting-plugin

PostCSS https://www.npmjs.com/package/postcss-extract-media-query

First, a definition, since it's pretty important: A stable sort is one that's guaranteed not to reorder elements with identical keys.

Recommendations:

Quick sort: When you don't need a stable sort and average case performance matters more than worst case performance. A quick sort is O(N log N) on average, O(N^2) in the worst case. A good implementation uses O(log N) auxiliary storage in the form of stack space for recursion.

Merge sort: When you need a stable, O(N log N) sort, this is about your only option. The only downsides to it are that it uses O(N) auxiliary space and has a slightly larger constant than a quick sort. There are some in-place merge sorts, but AFAIK they are all either not stable or worse than O(N log N). Even the O(N log N) in place sorts have so much larger a constant than the plain old merge sort that they're more theoretical curiosities than useful algorithms.

Heap sort: When you don't need a stable sort and you care more about worst case performance than average case performance. It's guaranteed to be O(N log N), and uses O(1) auxiliary space, meaning that you won't unexpectedly run out of heap or stack space on very large inputs.

Introsort: This is a quick sort that switches to a heap sort after a certain recursion depth to get around quick sort's O(N^2) worst case. It's almost always better than a plain old quick sort, since you get the average case of a quick sort, with guaranteed O(N log N) performance. Probably the only reason to use a heap sort instead of this is in severely memory constrained systems where O(log N) stack space is practically significant.

Insertion sort: When N is guaranteed to be small, including as the base case of a quick sort or merge sort. While this is O(N^2), it has a very small constant and is a stable sort.

Bubble sort, selection sort: When you're doing something quick and dirty and for some reason you can't just use the standard library's sorting algorithm. The only advantage these have over insertion sort is being slightly easier to implement.

Non-comparison sorts: Under some fairly limited conditions it's possible to break the O(N log N) barrier and sort in O(N). Here are some cases where that's worth a try:

Counting sort: When you are sorting integers with a limited range.

Radix sort: When log(N) is significantly larger than K, where K is the number of radix digits.

Bucket sort: When you can guarantee that your input is approximately uniformly distributed.

Your C++ is showing.

There is no delete in java, and all objects are created on the heap. The JVM has a garbage collector that relies on reference counts.

Once there are no more references to an object, it becomes available for collection by the garbage collector.

myObject = null may not do it; for example:

Foo myObject = new Foo(); // 1 reference
Foo myOtherObject = myObject; // 2 references
myObject = null; // 1 reference

All this does is set the reference myObject to null, it does not affect the object myObject once pointed to except to simply decrement the reference count by 1. Since myOtherObject still refers to that object, it is not yet available to be collected.

The best bet is to stash the changes and switch branch. For switching branches, you need a clean state. So stash them, checkout a new branch and apply the changes on the new branch and commit it

I recently had some issues with a VirtualHost. I used a2ensite to enable a host but before running a restart (which would kill the server on fail) I ran

apache2ctl -S

Which gives you some info about what's going on with your virtual hosts. It's not perfect, but it helps.

In ES6, you can do like this.

var key = "name";
var person = {[key]:"John"}; // same as var person = {"name" : "John"}
console.log(person); // should print  Object { name="John"}

    var key = "name";_x000D_
    var person = {[key]:"John"};_x000D_
    console.log(person); // should print  Object { name="John"}

Its called Computed Property Names, its implemented using bracket notation( square brackets) []

Example: { [variableName] : someValue }

Starting with ECMAScript 2015, the object initializer syntax also supports computed property names. That allows you to put an expression in brackets [], that will be computed and used as the property name.

For ES5, try something like this

var yourObject = {};

yourObject[yourKey] = "yourValue";

console.log(yourObject );

example:

var person = {};
var key = "name";

person[key] /* this is same as person.name */ = "John";

console.log(person); // should print  Object { name="John"}

    var person = {};_x000D_
    var key = "name";_x000D_
    _x000D_
    person[key] /* this is same as person.name */ = "John";_x000D_
    _x000D_
    console.log(person); // should print  Object { name="John"}

Here is another example, for compiling a java file in a nested directory.

I was trying to build this from the command line. This is an example from 'gradle', which has dependency 'commons-collection.jar'. For more info, please see 'gradle: java quickstart' example. -- of course, you would use the 'gradle' tools to build it. But i thought to extend this example, for a nested java project, with a dependent jar.

Note: You need the 'gradle binary or source' distribution for this, example code is in: 'samples/java/quickstart'

% mkdir -p temp/classes
% curl --get \
    http://central.maven.org/maven2/commons-collections/commons-collections/3.2.2/commons-collections-3.2.2.jar \
        --output commons-collections-3.2.2.jar

% javac -g -classpath commons-collections-3.2.2.jar \
     -sourcepath src/main/java -d temp/classes \
      src/main/java/org/gradle/Person.java 

% jar cf my_example.jar -C temp/classes org/gradle/Person.class
% jar tvf my_example.jar

One way is to convert your array to an object and use it in scope (simulation of an array). This way has the benefit of maintaining the template.

$scope.telephone = {};
for (var i = 0, l = $scope.phones.length; i < l; i++) {
  $scope.telephone[i.toString()] = $scope.phone[i];
}

<input type="text" ng-model="telephone[0.toString()]" />
<input type="text" ng-model="telephone[1.toString()]" />

and on save, change it back.

$scope.phones = [];
for (var i in $scope.telephone) {
  $scope.phones[parseInt(i)] = $scope.telephone[i];
}

Best way is use DateTime object to convert your date.

$myDateTime = DateTime::createFromFormat('Y-m-d', $weddingdate);
$formattedweddingdate = $myDateTime->format('d-m-Y');

Note: It will support for PHP 5 >= 5.3.0 only.

Is this what you are after? Just index the element and assign a new value.

A[2,1]=150

A
Out[345]: 
array([[ 1,  2,  3,  4],
       [ 5,  6,  7,  8],
       [ 9, 150, 11, 12],
       [13, 14, 15, 16]])

You want to check the result of scanf() to make sure there was a successful conversion; if there wasn't, then one of three things is true:

1. scanf() is choking on a character that isn't valid for the %f conversion specifier (i.e., something that isn't a digit, dot, 'e', or 'E');
2. scanf() has detected EOF;
3. scanf() has detected an error on reading stdin.

Example:

int moreData = 1;
...
printf("Input no: ");
fflush(stdout);
/**
 * Loop while moreData is true
 */
while (moreData)
{
  errno = 0;
  int itemsRead = scanf("%f", &input);
  if (itemsRead == 1)
  {
    printf("Output: %f\n", input);
    printf("Input no: ");
    fflush(stdout);
  }
  else
  {
    if (feof(stdin))
    {
      printf("Hit EOF on stdin; exiting\n");
      moreData = 0;
    }
    else if (ferror(stdin))
    {
      /**
       * I *think* scanf() sets errno; if not, replace
       * the line below with a regular printf() and
       * a generic "read error" message.
       */
      perror("error during read");
      moreData = 0;
    }
    else
    {
      printf("Bad character stuck in input stream; clearing to end of line\n");
      while (getchar() != '\n')
        ; /* empty loop */
      printf("Input no: ");
      fflush(stdout);
    }
 }

If you are passing (like me) all the parameters like port, username, password through a system and you are not allow to modify the code, then you can do that easy change on the web.config:

<system.net>
  <mailSettings>
    <smtp>
      <network enableSsl="true"/>
    </smtp>
  </mailSettings>
</system.net>

self and $self aren't the same. The former is the object pointed to by "this" and the latter a jQuery object whose "scope" is the object pointed to by "this". Similarly, $body isn't the body DOM element but the jQuery object whose scope is the body element.

Sometimes is useful to override method onBackPressed() because in case you work with fragments and you're changing between them if you push backbutton they return to the previous fragment.

Try importing this in build.gradle dependencies

compile group: 'com.googlecode.json-simple', name: 'json-simple', version: '1.1'

If you don't mind a small library dependency, Flurl.Http [disclosure: I'm the author] makes this uber-simple. Its PostJsonAsync method takes care of both serializing the content and setting the content-type header, and ReceiveJson deserializes the response. If the accept header is required you'll need to set that yourself, but Flurl provides a pretty clean way to do that too:

using Flurl.Http;

var result = await "http://example.com/"
    .WithHeader("Accept", "application/json")
    .PostJsonAsync(new { ... })
    .ReceiveJson<TResult>();

Flurl uses HttpClient and Json.NET under the hood, and it's a PCL so it'll work on a variety of platforms.

PM> Install-Package Flurl.Http

Another option for the same result with ConstraintSet animation:

1) Put all the animated views in one ConstraintLayout

2) Animate it from code like this (if you want some more effects its up to you..this is only example)

menuItem1 and menuItem2 is the first and second FABs in menu, descriptionItem1 and descriptionItem2 is the description to the left of menu, parentConstraintLayout is the root ConstraintLayout wich contains all the animated views, isMenuOpened is some function to change open/closed flag in the state

I put animation code in extension file but its not necessary.

fun FloatingActionButton.expandMenu(
    menuItem1: View,
    menuItem2: View,
    descriptionItem1: TextView,
    descriptionItem2: TextView,
    parentConstraintLayout: ConstraintLayout,
    isMenuOpened: (Boolean)-> Unit
) {
    val constraintSet = ConstraintSet()
    constraintSet.clone(parentConstraintLayout)

    constraintSet.setVisibility(descriptionItem1.id, View.VISIBLE)
    constraintSet.clear(menuItem1.id, ConstraintSet.TOP)
    constraintSet.connect(menuItem1.id, ConstraintSet.BOTTOM, this.id, ConstraintSet.TOP, 0)
    constraintSet.connect(menuItem1.id, ConstraintSet.START, this.id, ConstraintSet.START, 0)
    constraintSet.connect(menuItem1.id, ConstraintSet.END, this.id, ConstraintSet.END, 0)

    constraintSet.setVisibility(descriptionItem2.id, View.VISIBLE)
    constraintSet.clear(menuItem2.id, ConstraintSet.TOP)
    constraintSet.connect(menuItem2.id, ConstraintSet.BOTTOM, menuItem1.id, ConstraintSet.TOP, 0)
    constraintSet.connect(menuItem2.id, ConstraintSet.START, this.id, ConstraintSet.START, 0)
    constraintSet.connect(menuItem2.id, ConstraintSet.END, this.id, ConstraintSet.END, 0)

    val transition = AutoTransition()
    transition.duration = 150
    transition.interpolator = AccelerateInterpolator()

    transition.addListener(object: Transition.TransitionListener {
        override fun onTransitionEnd(p0: Transition) {
            isMenuOpened(true)
        }
        override fun onTransitionResume(p0: Transition) {}
        override fun onTransitionPause(p0: Transition) {}
        override fun onTransitionCancel(p0: Transition) {}
        override fun onTransitionStart(p0: Transition) {}
    })

    TransitionManager.beginDelayedTransition(parentConstraintLayout, transition)
    constraintSet.applyTo(parentConstraintLayout)
}

here is my solution:

$(el).on('touchstart', function(e) {
    var link = $(e.target.parentNode).closest('a')  
    if(link.length > 0) {
        window.location.href = link.attr('href');
    }
});

It worked for me after adding particular version of node-sass package ([email protected])

You can use flexbox to center your text. By the way no need for extra containers because text is considered as anonymous flex item.

From flexbox specs:

Each in-flow child of a flex container becomes a flex item, and each contiguous run of text that is directly contained inside a flex container is wrapped in an anonymous flex item. However, an anonymous flex item that contains only white space (i.e. characters that can be affected by the white-space property) is not rendered (just as if it were display:none).

So just make grid items as flex containers (display: flex), and add align-items: center and justify-content: center to center both vertically and horizontally.

Also performed optimization of HTML and CSS:

body {_x000D_
  margin: 0;_x000D_
  padding: 0;_x000D_
}_x000D_

For those who know a little bit of actionscript, you can check for flash player, with minimal effort, and make a flash preloader, that you can also export to html5/Javascript/Jquery. To use if the flash player is not detected, check examples on how to do this with the youtube role back to html5 player:) And create your own. I do not have the details, becouse i have not started yet, if i dont forgot, i wil post it later and will try out some standerd Jquery code to mine.

request.getSession().setAttribute("SUBFAMILY", subFam);
request.getSession().getAttribute("SUBFAMILY");

Simply copy the entire working directory contents (including the hidden .git directory). This will move the entire working directory to the new directory and will not affect the remote repository on GitHub.

If you are using GitHub for Windows, you may move the repository using the method as above. However, when you click on the repository in the application it will be unable to find it. To resolve this simply click on the blue circle with the !, select Find It and then browse to the new directory.

Have you tried your own code?
This should work:

SELECT * FROM people WHERE age BETWEEN x AND y

If you want PHP to treat $_GET['select2'] as an array of options just add square brackets to the name of the select element like this: <select name="select2[]" multiple …

Then you can acces the array in your PHP script

<?php
header("Content-Type: text/plain");

foreach ($_GET['select2'] as $selectedOption)
    echo $selectedOption."\n";

$_GET may be substituted by $_POST depending on the <form method="…" value.

Look for a little clipboard icon that pops up at the end of the material you pasted. Click on this and choose "keep text only".

You should try with the parent elements;

html, body, form, main {
    height: 100%;
}

Then this will be enough :

#s7 {
   height: 100%;
}

This is called an initialization list. It is a way of initializing class members. There are benefits to using this instead of simply assigning new values to the members in the body of the constructor, but if you have class members which are constants or references they must be initialized.

I encountered this error when the JDK that I compiled the app under was different from the tomcat JVM. I verified that the Tomcat manager was running jvm 1.6.0 but the app was compiled under java 1.7.0.

After upgrading Java and changing JAVA_HOME in our startup script (/etc/init.d/tomcat) the error went away.

check ur WebApiConfig and add this

GlobalConfiguration.Configuration.Formatters.XmlFormatter.SupportedMediaTypes.Clear();

$(document).ready(function() {
    $("#form1").validate({
        rules: {
            field1: "required"
        },
        messages: {
            field1: "Please specify your name"
        }
    })
});

<form id="form1" name="form1">
     Field 1: <input id="field1" type="text" class="required">
    <input id="btn" type="submit" value="Validate">
</form>

You are also you using type="button". And I'm not sure why you ought to separate the submit button, place it within the form. It's more proper to do it that way. This should work.

Maybe a bit late to answer but i would like to share my way. I found an easy way with threads in the main program for a winform application.

Lets say you have your form "splashscreen" with an animation, and your "main" which has all your application code.

 [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Thread mythread;
        mythread = new Thread(new ThreadStart(ThreadLoop));
        mythread.Start();
        Application.Run(new MainForm(mythread));           
    }

    public static void ThreadLoop()
    {
        Application.Run(new SplashScreenForm());           
    }

In your main form in the constructor:

 public MainForm(Thread splashscreenthread)
    {
        InitializeComponent();

        //add your constructor code

        splashscreenthread.Abort();            
    }

This way the splashscreen will last just the time for your main form to load.

Your splashcreen form should have his own way to animate/display information. In my project my splashscreen start a new thread, and every x milliseconds it changes his main picture to another which is a slightly different gear, giving the illusion of a rotation.

example of my splashscreen:

int status = 0;
private bool IsRunning = false;
    public Form1()
    {
        InitializeComponent();
        StartAnimation();
    }

    public void StartAnimation()
    {
        backgroundWorker1.WorkerReportsProgress = false;
        backgroundWorker1.WorkerSupportsCancellation = true;
        IsRunning = true;
        backgroundWorker1.RunWorkerAsync();
    }


    public void StopAnimation()
    {
        backgroundWorker1.CancelAsync();
    }

    delegate void UpdatingThreadAnimation();
    public void UpdateAnimationFromThread()
    {

        try
        {
            if (label1.InvokeRequired == false)
            {
                UpdateAnimation();
            }
            else
            {
                UpdatingThreadAnimation d = new UpdatingThreadAnimation(UpdateAnimationFromThread);
                this.Invoke(d, new object[] { });
            }
        }
        catch(Exception e)
        {

        }
    }

 private void UpdateAnimation()
    {
    if(status ==0) 
    {
    // mypicture.image = image1
     }else if(status ==1)
     {
    // mypicture.image = image2
     }
    //doing as much as needed

      status++;
        if(status>1) //change here if you have more image, the idea is to set a cycle of images
        {
            status = 0;
        }
        this.Refresh();
    }

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
    {
        BackgroundWorker worker = sender as BackgroundWorker;
        while (IsRunning == true)
        {
            System.Threading.Thread.Sleep(100);
            UpdateAnimationFromThread();
        }
    }

Hope this will help some people. Sorry if i have made some mistakes. English is not my first language.

The git package installed on your system includes bash files to aid you in creating an informative prompt. To create colors, you will need to insert terminal escape sequences into your prompt. And, the final ingredient is to update your prompt after each command gets executed by using the built-in variable PROMPT_COMMAND.

Edit your ~/.bashrc to include the following, and you should get the prompt in your question, modulo some color differences.

#
# Git provides a bash file to create an informative prompt. This is its standard
# location on Linux. On Mac, you should be able to find it under your Git
# installation. If you are unable to find the file, I have a copy of it on my GitHub.
#
# https://github.com/chadversary/home/blob/42cf697ba69d4d474ca74297cdf94186430f1384/.config/kiwi-profile/40-git-prompt.sh
#
source /usr/share/git/completion/git-prompt.sh

#
# Next, we need to define some terminal escape sequences for colors. For a fuller
# list of colors, and an example how to use them, see my bash color file on my GitHub
# and my coniguration for colored man pages.
#
# https://github.com/chadversary/home/blob/42cf697ba69d4d474ca74297cdf94186430f1384/.config/kiwi-profile/10-colors.sh
# https://github.com/chadversary/home/blob/42cf697ba69d4d474ca74297cdf94186430f1384/.config/kiwi-profile/40-less.sh
#
color_start='\e['
color_end='m'
color_reset='\e[0m'
color_bg_blue='44'

#
# To get a fancy git prompt, it's not sufficient to set PS1. Instead, we set PROMPT_COMMAND,
# a built in Bash variable that gets evaluated before each render of the prompt.
#
export PROMPT_COMMAND="PS1=\"\${color_start}\${color_bg_blue}\${color_end}\u@\h [\w\$(__git_ps1 \" - %s\")]\${color_reset}\n\$ \""

#
# If you find that the working directory that appears in the prompt is ofter too long,
# then trim it.
#
export PROMPT_DIRTRIM=3

In case of image stacks, I find it easier to use scikit-image to read, and matplotlib to show or save. I have handled 16-bit TIFF image stacks with the following code.

from skimage import io
import matplotlib.pyplot as plt

# read the image stack
img = io.imread('a_image.tif')
# show the image
plt.imshow(mol,cmap='gray')
plt.axis('off')
# save the image
plt.savefig('output.tif', transparent=True, dpi=300, bbox_inches="tight", pad_inches=0.0)

If you wanna update a table with that DateTime, you can use your SQL string like this example:

int fieldId;
DateTime myDateTime = DateTime.Now
string sql = string.Format(@"UPDATE TableName SET DateFieldName='{0}' WHERE FieldID={1}", myDateTime.ToString("yyyy-MM-dd HH:mm:ss"), fieldId.ToString());

If you want your CSS to be copied into the output without being processed, you can use the (inline) directive. e.g.,

@import (inline) '../timepicker/jquery.ui.timepicker.css';

Xcode 5 lost my Mac Provisioning Profile while the one for iOS was present. The tips elsewhere helped solve the problem; this is what I did, because I noticed the lists were too short and did not include *Mac Team Provisioning Profile: **

1. Xcode menu => Preferences => Accounts
2. Select the Apple ID in the left panel.
3. Click the View Details button on the right.
4. In the pop-over that follows click the round refresh arrow. The lists will refresh after the download from the Member Center finishes. This can take a few minutes.
5. The provisioning profiles can then be selected in a Mac project under Build Settings => Code Signing => Provisioning Profile.

You can append it to the tbody using the appendTo method like this:

$(() => {
   $("<tr><td>my data</td><td>more data</td></tr>").appendTo("tbody");
});

You'll probably want to use the latest JQuery and ECMAScript. Then you can use a back-end language to add your data to the table. You can also wrap it in a variable like so:

$(() => {
  var t_data = $('<tr><td>my data</td><td>more data</td></tr>');
  t_data.appendTo('tbody');
});

Try that:

$createdAt = Carbon::parse(date_format($item['created_at'],'d/m/Y H:i:s');
$createdAt= $createdAt->format('M d Y');

Pure bash, no basename, no variable juggling. Set a string and echo:

p=/the/path/foo.txt
echo "${p//+(*\/|.*)}"

Output:

foo

Note: the bash extglob option must be "on", (Ubuntu sets extglob "on" by default), if it's not, do:

shopt -s extglob

Walking through the ${p//+(*\/|.*)}:

1. ${p -- start with $p.
2. // substitute every instance of the pattern that follows.
3. +( match one or more of the pattern list in parenthesis, (i.e. until item #7 below).
4. 1st pattern: *\/ matches anything before a literal "/" char.
5. pattern separator | which in this instance acts like a logical OR.
6. 2nd pattern: .* matches anything after a literal "." -- that is, in bash the "." is just a period char, and not a regex dot.
7. ) end pattern list.
8. } end parameter expansion. With a string substitution, there's usually another / there, followed by a replacement string. But since there's no / there, the matched patterns are substituted with nothing; this deletes the matches.

Relevant man bash background:

1. pattern substitution:

  ${parameter/pattern/string}
          Pattern substitution.  The pattern is expanded to produce a pat
          tern just as in pathname expansion.  Parameter is  expanded  and
          the  longest match of pattern against its value is replaced with
          string.  If pattern begins with /, all matches  of  pattern  are
          replaced   with  string.   Normally  only  the  first  match  is
          replaced.  If pattern begins with #, it must match at the begin-
          ning of the expanded value of parameter.  If pattern begins with
          %, it must match at the end of the expanded value of  parameter.
          If string is null, matches of pattern are deleted and the / fol
          lowing pattern may be omitted.  If parameter is @ or *, the sub
          stitution  operation  is applied to each positional parameter in
          turn, and the expansion is the resultant list.  If parameter  is
          an  array  variable  subscripted  with  @ or *, the substitution
          operation is applied to each member of the array  in  turn,  and
          the expansion is the resultant list.

2. extended pattern matching:

  If the extglob shell option is enabled using the shopt builtin, several
   extended  pattern  matching operators are recognized.  In the following
   description, a pattern-list is a list of one or more patterns separated
   by a |.  Composite patterns may be formed using one or more of the fol
   lowing sub-patterns:

          ?(pattern-list)
                 Matches zero or one occurrence of the given patterns
          *(pattern-list)
                 Matches zero or more occurrences of the given patterns
          +(pattern-list)
                 Matches one or more occurrences of the given patterns
          @(pattern-list)
                 Matches one of the given patterns
          !(pattern-list)
                 Matches anything except one of the given patterns

I think that this should work:

.element {
   -webkit-transition: all .3s;
   -moz-transition: all .3s;
   -o-transition: all .3s;
   transition: all .3s;
}

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.

You can also do this with named ranges so you don't have to copy the cells from Sheet1 to Sheet2:

1. Define a named range, say Sheet1Vals for the column that has the values on which you want to base your condition. You can define a new named range by using the Insert\Name\Define... menu item. Type in your name, then use the cell browser in the Refers to box to select the cells you want in the range. If the range will change over time (add or remove rows) you can use this formula instead of selecting the cells explicitly:

   =OFFSET('SheetName'!$COL$ROW,0,0,COUNTA('SheetName'!$COL:$COL)).

   Add a -1 before the last ) if the column has a header row.

2. Define a named range, say Sheet2Vals for the column that has the values you want to conditionally format.

3. Use the Conditional Formatting dialog to create your conditions. Specify Formula Is in the dropdown, then put this for the formula:

   =INDEX(Sheet1Vals, MATCH([FirstCellInRange],Sheet2Vals))=[Condition]

   where [FirstCellInRange] is the address of the cell you want to format and [Condition] is the value your checking.

For example, if my conditions in Sheet1 have the values of 1, 2 and 3 and the column I'm formatting is column B in Sheet2 then my conditional formats would be something like:

=INDEX(Sheet1Vals, MATCH(B1,Sheet2Vals))=1
=INDEX(Sheet1Vals, MATCH(B1,Sheet2Vals))=2
=INDEX(Sheet1Vals, MATCH(B1,Sheet2Vals))=3

You can then use the format painter to copy these formats to the rest of the cells.

Another form that works with Postgres 9.1+ is combining a Common Table Expression with the USING statement for the join.

WITH prod AS (select m_product_id, upc from m_product where upc='7094')
DELETE FROM m_productprice B
USING prod C
WHERE B.m_product_id = C.m_product_id 
AND B.m_pricelist_version_id = '1000020';

You have a class on your CSS that is overwriting your width and height, the class reads as such:

.postItem img {
    height: auto;
    width: 450px;
}

Remove that and your width/height properties on the img tag should work.

I tried a few solutions but at the end used replace. My data set is part numbers and I fairly know what to expect. But just for sanity, I used PHP to build the long query:

$dirty = array(' ', '-', '.', ',', ':', '?', '/', '!', '&', '@');
$query = 'part_no';
foreach ($dirty as $dirt) {
    $query = "replace($query,'$dirt','')";
}
echo $query;

This outputs something I used to get a headache from:

replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(part_no,' ',''),'-',''),'.',''),',',''),':',''),'?',''),'/',''),'!',''),'&',''),'@','')

catching in this fashion, in my experience, is dangerous. Any error thrown in the entire stack will be caught, not just an error from this promise (which is probably not what you want).

The second argument to a promise is already a rejection/failure callback. It's better and safer to use that instead.

Here's a typescript typesafe one-liner I wrote to handle this:

function wait<R, E>(promise: Promise<R>): [R | null, E | null] {
  return (promise.then((data: R) => [data, null], (err: E) => [null, err]) as any) as [R, E];
}

// Usage
const [currUser, currUserError] = await wait<GetCurrentUser_user, GetCurrentUser_errors>(
  apiClient.getCurrentUser()
);

You could also do this:

$dump = print_r($variable, true);

Take a look at ArrayList#addAll(Collection)

Appends all of the elements in the specified collection to the end of this list, in the order that they are returned by the specified collection's Iterator. The behaviour of this operation is undefined if the specified collection is modified while the operation is in progress. (This implies that the behaviour of this call is undefined if the specified collection is this list, and this list is nonempty.)

So basically you could use

ArrayList<String> listOfStrings = new ArrayList<>(list.size());
listOfStrings.addAll(list);

What worked for me was to pass the activity instead of the context.

I wanted a custom layout for my dialog, but to keep my code separate, I created it in a separate Class, else I would have to copy and paste that chunk of code into every activity where I want to use the dialog.

Solution explains my situation but it gives the core solution:

1. As I was using a ViewAdapter I initialised the adapter with the Activity (not context ex. ->[kotlin] activity: Activity) as a parameter -> ex. [kotlin] this@MainActivity
2. Then I passed that parameter to the Viewholder
3. After which passing it again to the class that will inflate the Dialog.

Use the activity[optional name]: Activity[mandatory type] every where until it gets to the dialog you want to inflate

Its a lot of passing around, but it does make more sense over copy and pasting the same code everywhere

Just something I found for Wordpress users,

As obvious as it sounds, If your div is returning some AJAX content based on say a header that would commonly link out to a new post page, some tutorials will say to return false since you're returning the post data on the same page and the return would prevent the page from moving. However if you return false, you also prevent Fancybox2 from doing it's thing as well. I spent hours trying to figure that stupid simple thing out.

So for these kind of links, just make sure that the href property is the hashed (#) div you wish to select, and in your javascript, make sure that you do not return false since you no longer will need to.

Simple I know ^_^

Querying a simple subquery sorted descending, followed by sorting on the same column ascending does the trick.

SELECT * FROM 
    (SELECT TOP 200 * FROM [table] t2 ORDER BY t2.[column] DESC) t1
    ORDER BY t1.[column]

So there are two easy ways to make this work. The solution posted by Bert F works fine if you don't need to supply any other special Oracle-specific connection properties. The format for that is:

jdbc:oracle:thin:@//HOSTNAME:PORT/SERVICENAME

However, if you need to supply other Oracle-specific connection properties then you need to use the long TNSNAMES style. I had to do this recently to enable Oracle shared connections (where the server does its own connection pooling). The TNS format is:

jdbc:oracle:thin:@(description=(address=(host=HOSTNAME)(protocol=tcp)(port=PORT))(connect_data=(service_name=SERVICENAME)(server=SHARED)))

If you're familiar with the Oracle TNSNAMES file format, then this should look familiar to you. If not then just Google it for the details.

One more for loop variant, looks cleaner to me than one with enumerate():

for idx in range(len(list)):
    list[idx]=... # set a new value
    # some other code which doesn't let you use a list comprehension

You may try to inherit property from the base class:

var width = 2;_x000D_
var interval = setInterval(function () {_x000D_
    var element = document.getElementById('box');_x000D_
    width += 0.0625;_x000D_
    element.style.width = width + 'em';_x000D_
    if (width >= 7) clearInterval(interval);_x000D_
}, 50);

.box {_x000D_
    /* Set property */_x000D_
    width:4em;_x000D_
    height:2em;_x000D_
    background-color:#d42;_x000D_

You need to understand that a database server or DBA would not want just anyone to be able to connect or modify the contents of the server. This is the whole purpose of security accounts. If a single username/password would work on just any machine, it would provide no protection.

That "sa" thing you have heard of, does not work with SQL Server 2005, 2008 or 2012. I am not sure about previous versions though. I believe somewhere in the early days of SQL Server, the default username and password used to be sa/sa, but that is no longer the case.

FYI, database security and roles are much more complicated nowadays. You may want to look into the details of Windows-based authentication. If your SQL Server is configured for it, you don't need any username/password in the connection string to connect to it. All you need to change is the server machine name and the same connection string will work with both your machines, given both have same database name of course.

If you are already spending time in Visual Studio, then you can always use the Server Explorer to connect to any .Net compliant database server.

Provided you're using Professional or greater, you can create and edit tables and databases, run queries, etc.

i had the same problem with my jar the solution

1. Create the MANIFEST.MF file:

Manifest-Version: 1.0

Sealed: true

Class-Path: . lib/jarX1.jar lib/jarX2.jar lib/jarX3.jar

Main-Class: com.MainClass

2. Right click on project, Select Export.

select export all outpout folders for checked project

3. select using existing manifest from workspace and select the MANIFEST.MF file

This worked for me :)

Assuming you've got access to a standard Unix shell and/or cygwin environment:

tr -s ' ' '\n' < yourfile | sort | uniq -d -c
       ^--space char

Basically: convert all space characters to linebreaks, then sort the tranlsated output and feed that to uniq and count duplicate lines.

Use below code to provide different color to actionbar text and actionbar background just use below theme in manifest against the activity in which you want output :)

<style name="MyTheme" parent="@android:style/Theme.Holo.Light">
    <item name="android:actionBarStyle">@style/MyActionBar</item>
</style>

<style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
    <item name="android:titleTextStyle">@style/TitleBarTextColor</item>
    <item name="android:background">YOUR_COLOR_CODE</item>
</style>

<style name="TitleBarTextColor" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title">
    <item name="android:textColor">YOUR_COLOR_CODE</item>
</style>

In simple words

$.ajax("info.txt").done(function(data) {
  alert(data);
}).fail(function(data){
  alert("Try again champ!");
});

if its get the info.text then it will alert and whatever function you add or if any how unable to retrieve info.text from the server then alert or error function.

Converting your lists to sets will tell you that they contain the same elements. But this method cannot confirm that they contain the same number of all elements. For example, your method will fail in this case:

L1 = [1,2,2,3]
L2 = [1,2,3,3]

You are likely better off sorting the two lists and comparing them:

def checkEqual(L1, L2):
    if sorted(L1) == sorted(L2):
        print "the two lists are the same"
        return True
    else:
        print "the two lists are not the same"
        return False

Note that this does not alter the structure/contents of the two lists. Rather, the sorting creates two new lists

If we use SQL Server >= 2005, then we can solve the task with one select only:

declare @t table (
    Id      int ,
    Section int,
    Moment  date
);

insert into @t values

I'd heartily recommend that you read Other languages have "variables" (I added it as a related link) – in two minutes you'll know that Python has "names", not "variables".

val = None
# ...
if val is None:
   val = any_object

You must put a FrameLayout as Main view then put inside a RelativeLayout with ScrollView and at least your RecyclerView, it works for me.

The real trick here is the RelativeLayout...

Happy to help.

MIME stands for Multipurpose Internet Mail Extensions. It's a way of identifying files on the Internet according to their nature and format.

For example, using the Content-type header value defined in a HTTP response, the browser can open the file with the proper extension/plugin.

Internet Media Type (also Content-type) is the same as a MIME type. MIME types were originally created for emails sent using the SMTP protocol. Nowadays, this standard is used in a lot of other protocols, hence the new naming convention "Internet Media Type".

A MIME type is a string identifier composed of two parts: a type and a subtype.

• The "type" refers to a logical grouping of many MIME types that are closely related to each other; it's no more than a high level category.
• "subtypes" are specific to one file type within the "type".

The x- prefix of a MIME subtype simply means that it's non-standard.
The vnd prefix means that the MIME value is vendor specific.

You can run the dropdb command from the command line:

dropdb 'database name'

Note that you have to be a superuser or the database owner to be able to drop it.

You can also check the pg_stat_activity view to see what type of activity is currently taking place against your database, including all idle processes.

SELECT * FROM pg_stat_activity WHERE datname='database name';

Note that from PostgreSQL v13 on, you can disconnect the users automatically with

DROP DATABASE dbname FORCE;

or

dropdb -f dbname

>>> a = 'ZENOVW'
>>> b = sorted(a)
>>> print b
['E', 'N', 'O', 'V', 'W', 'Z']

sorted returns a list, so you can make it a string again using join:

>>> c = ''.join(b)

which joins the items of b together with an empty string '' in between each item.

>>> print c
'ENOVWZ'

No way to do that other than validate file extension with JavaScript when input path is populated by the file picker. To implement anything fancier you need to write your own component for whichever browser you want (activeX or XUL)

There's an "accept" attribute in HTML4.01 but I'm not aware of any browser supporting it - e.g. accept="image/gif,image/jpeg - so it's a neat but impractical spec

The fundamental difference, which no other answer seems to have mentioned, is that XML is a markup language (as it actually says in its name), whereas JSON is a way of representing objects (as also noted in its name).

A markup language is a way of adding extra information to free-flowing plain text, e.g

Here is some text.

With XML (using a certain element vocabulary) you can put:

<Document>
    <Paragraph Align="Center">
        Here <Bold>is</Bold> some text.
    </Paragraph>
</Document>

This is what makes markup languages so useful for representing documents.

An object notation like JSON is not as flexible. But this is usually a good thing. When you're representing objects, you simply don't need the extra flexibility. To represent the above example in JSON, you'd actually have to solve some problems manually that XML solves for you.

{
    "Paragraphs": [
        {
            "align": "center",
            "content": [
                "Here ", {
                    "style" : "bold",
                    "content": [ "is" ]
                },
                " some text."
            ]
        }
    ]
}

It's not as nice as the XML, and the reason is that we're trying to do markup with an object notation. So we have to invent a way to scatter snippets of plain text around our objects, using "content" arrays that can hold a mixture of strings and nested objects.

On the other hand, if you have typical a hierarchy of objects and you want to represent them in a stream, JSON is better suited to this task than HTML.

{
    "firstName": "Homer",
    "lastName": "Simpson",
    "relatives": [ "Grandpa", "Marge", "The Boy", "Lisa", "I think that's all of them" ]
} 

Here's the logically equivalent XML:

<Person>
    <FirstName>Homer</FirstName>
    <LastName>Simpsons</LastName>
    <Relatives>
        <Relative>Grandpa</Relative>
        <Relative>Marge</Relative>
        <Relative>The Boy</Relative>
        <Relative>Lisa</Relative>
        <Relative>I think that's all of them</Relative>
    </Relatives>
</Person>

JSON looks more like the data structures we declare in programming languages. Also it has less redundant repetition of names.

But most importantly of all, it has a defined way of distinguishing between a "record" (items unordered, identified by names) and a "list" (items ordered, identified by position). An object notation is practically useless without such a distinction. And XML has no such distinction! In my XML example <Person> is a record and <Relatives> is a list, but they are not identified as such by the syntax.

Instead, XML has "elements" versus "attributes". This looks like the same kind of distinction, but it's not, because attributes can only have string values. They cannot be nested objects. So I couldn't have applied this idea to <Person>, because I shouldn't have to turn <Relatives> into a single string.

By using an external schema, or extra user-defined attributes, you can formalise a distinction between lists and records in XML. The advantage of JSON is that the low-level syntax has that distinction built into it, so it's very succinct and universal. This means that JSON is more "self describing" by default, which is an important goal of both formats.

So JSON should be the first choice for object notation, where XML's sweet spot is document markup.

Unfortunately for XML, we already have HTML as the world's number one rich text markup language. An attempt was made to reformulate HTML in terms of XML, but there isn't much advantage in this.

So XML should (in my opinion) have been a pretty limited niche technology, best suited only for inventing your own rich text markup languages if you don't want to use HTML for some reason. The problem was that in 1998 there was still a lot of hype about the Web, and XML became popular due to its superficial resemblance to HTML. It was a strange design choice to try to apply to hierarchical data a syntax actually designed for convenient markup.

The easiest way to concat a static text string to a selected value is to use element.

<a>
  <xsl:attribute name="href"> 
    <xsl:value-of select="/*/properties/property[@name='report']/@value" />
    <xsl:text>staticIconExample.png</xsl:text>
  </xsl:attribute>
</a>

<input type="text" input-disabled="editableInput" />
<button ng-click="editableInput = !editableInput">enable/disable</button>

app.controller("myController", function(){
  $scope.editableInput = false;
});

app.directive("inputDisabled", function(){
  return function(scope, element, attrs){
    scope.$watch(attrs.inputDisabled, function(val){
      if(val)
        element.removeAttr("disabled");
      else
        element.attr("disabled", "disabled");
    });
  }
});

The Math.round method returns a long (or an int if you pass in a float), and Java's integer division is the culprit. Cast it back to a double, or use a double literal when dividing by 10. Either:

double total = (double) Math.round((num / sum * 100) * 10) / 10;

or

double total = Math.round((num / sum * 100) * 10) / 10.0;

Then you should get

27.3

Providing javac is set up through /etc/alternatives/javac, you can add to your .bash_profile:

JAVA_HOME=$(l=$(which javac) ; while : ; do nl=$(readlink ${l}) ; [ "$nl" ] || break ; l=$nl ; done ; echo $(cd $(dirname $l)/.. ; pwd) )
export JAVA_HOME

There is none.

Postal/zip codes around the world don't follow a common pattern. In some countries they are made up by numbers, in others they can be combinations of numbers an letters, some can contain spaces, others dots, the number of characters can vary from two to at least six...

What you could do (theoretically) is create a seperate regex for every country in the world, not recommendable IMO. But you would still be missing on the validation part: Zip code 12345 may exist, but 12346 not, maybe 12344 doesn't exist either. How do you check for that with a regex?

You can't.

If you want to parse a String to a char, whereas the String object represent more than one character, you just simply use the following expression: char c = (char) Integer.parseInt(s). Where s equals the String you want to parse. Most people forget that char's represent a 16-bit number, and thus can be a part of any numerical expression :)

Main issue is that you first need to set the location of your x and y ticks. Also, it helps to use the more object-oriented interface to matplotlib. Namely, interact with the axes object directly.

import matplotlib.pyplot as plt
import numpy as np
column_labels = list('ABCD')
row_labels = list('WXYZ')
data = np.random.rand(4,4)
fig, ax = plt.subplots()
heatmap = ax.pcolor(data)

# put the major ticks at the middle of each cell, notice "reverse" use of dimension
ax.set_yticks(np.arange(data.shape[0])+0.5, minor=False)
ax.set_xticks(np.arange(data.shape[1])+0.5, minor=False)


ax.set_xticklabels(row_labels, minor=False)
ax.set_yticklabels(column_labels, minor=False)
plt.show()

Hope that helps.

How about adding a space in the pattern attribute like pattern="[a-zA-Z0-9 ]+". If you want to support any kind of space try pattern="[a-zA-Z0-9\s]+"

Content (for text and not html):

http://www.quirksmode.org/css/content.html

But just to be clear, it is bad practice. Its support throughout browsers is shaky, and it's generally not a good idea. But in cases where you really have to use it, there it is.

If you don't need to initiate a post back when you press this button, then making the overhead of a server control isn't necesary.

<input id="addButton" type="button" value="Add" />

<script type="text/javascript" language="javascript">
     $(document).ready(function()
     {
         $('#addButton').click(function() 
         { 
             showDialog('#addPerson'); 
         });
     });
</script>

If you still need to be able to do a post back, you can conditionally stop the rest of the button actions with a little different code:

<asp:Button ID="buttonAdd" runat="server" Text="Add" />

<script type="text/javascript" language="javascript">
     $(document).ready(function()
     {
         $('#<%= buttonAdd.ClientID %>').click(function(e) 
         { 
             showDialog('#addPerson');

             if(/*Some Condition Is Not Met*/) 
                return false;
         });
     });
</script>

Specific to XCode 9.1:
You can refere to @Krunal's answer above or follow below steps

its bit tricky to adjust Simulator size.

If you want to zoom your simulator screen follow below steps :

• Goto Window->Uncheck Show Device Bezels

• Goto Window->select zoom

after doing this you can resize your simulator by dragging edges of simulator.

Pixel Accurate : Its to display your simulator in same size as Physical device pixels, if your screen size doesn't have enough resolution to cover dimension it would not enable Pixel Accurate option.

Alternate is change simulator to landscape mode by clicking ? + ? ,then you could click ? + 2 to select Pixel Accurate option (make sure you have disable Show Device Bezels to reduce size.

Here in this article is clearly explained: The $state service provides a number of useful methods for manipulating the state as well as pertinent data on the current state. The current state parameters are accessible on the $state service at the params key. The $stateParams service returns this very same object. Hence, the $stateParams service is strictly a convenience service to quickly access the params object on the $state service.

As such, no controller should ever inject both the $state service and its convenience service, $stateParams. If the $state is being injected just to access the current parameters, the controller should be rewritten to inject $stateParams instead.

If you'd like to initialize the array to values other than 0, with gcc you can do:

int array[1024] = { [ 0 ... 1023 ] = -1 };

This is a GNU extension of C99 Designated Initializers. In older GCC, you may need to use -std=gnu99 to compile your code.

CSS is object oriented. ID says instance, class says class.

You can use the following list as quick reference:

   /   = Root directory
   .   = This location
   ..  = Up a directory
   ./  = Current directory
   ../ = Parent of current directory
   ../../ = Two directories backwards

To better understand the volume instruction in dockerfile, let us learn the typical volume usage in mysql official docker file implementation.

VOLUME /var/lib/mysql

Reference: https://github.com/docker-library/mysql/blob/3362baccb4352bcf0022014f67c1ec7e6808b8c5/8.0/Dockerfile

The /var/lib/mysql is the default location of MySQL that store data files.

When you run test container for test purpose only, you may not specify its mounting point,e.g.

docker run mysql:8

then the mysql container instance will use the default mount path which is specified by the volume instruction in dockerfile. the volumes is created with a very long ID-like name inside the Docker root, this is called "unnamed" or "anonymous" volume. In the folder of underlying host system /var/lib/docker/volumes.

/var/lib/docker/volumes/320752e0e70d1590e905b02d484c22689e69adcbd764a69e39b17bc330b984e4

This is very convenient for quick test purposes without the need to specify the mounting point, but still can get best performance by using Volume for data store, not the container layer.

For a formal use, you will need to specify the mount path by using named volume or bind mount, e.g.

docker run  -v /my/own/datadir:/var/lib/mysql mysql:8

The command mounts the /my/own/datadir directory from the underlying host system as /var/lib/mysql inside the container.The data directory /my/own/datadir won't be automatically deleted, even the container is deleted.

Usage of the mysql official image (Please check the "Where to Store Data" section):

This works for me.

json.load() accepts file object, parses the JSON data, populates a Python dictionary with the data and returns it back to you.

Suppose JSON file is like this:

{
   "emp_details":[
                 {
                "emp_name":"John",
                "emp_emailId":"[email protected]"  
                  },
                {
                 "emp_name":"Aditya",
                 "emp_emailId":"[email protected]"
                }
              ] 
}

import json 

# Opening JSON file 
f = open('data.json',) 

# returns JSON object as  
# a dictionary 
data = json.load(f) 

# Iterating through the json 
# list 
for i in data['emp_details']: 
    print(i) 

# Closing file 
f.close()

#Output:
{'emp_name':'John','emp_emailId':'[email protected]'}
{'emp_name':'Aditya','emp_emailId':'[email protected]'}

  id: 'Myid',

  alt: 'MyAlt'
});
img.appendTo($('#YourDiv'));

I think "works fine in Firefox" is in the Quirks mode rendering only. In the Standard mode rendering, that might not work fine in Firefox too.

percentage depends on "containing block", instead of viewport.

CSS Specification says

The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the value computes to 'auto'.

so

#container { height: auto; }
#container #mainContentsWrapper { height: n%; }
#container #sidebarWrapper { height: n%; }

means

#container { height: auto; }
#container #mainContentsWrapper { height: auto; }
#container #sidebarWrapper { height: auto; }

To stretch to 100% height of viewport, you need to specify the height of the containing block (in this case, it's #container). Moreover, you also need to specify the height to body and html, because initial Containing Block is "UA-dependent".

All you need is...

html, body { height:100%; }
#container { height:100%; }

You will have the same object two times in your array, because object values are passed by reference. You have to create a new object like this

myElement.id = 244;
myElement.value = 3556;
myArray[0] = $.extend({}, myElement); //for shallow copy or
myArray[0] = $.extend(true, {}, myElement); // for deep copy

or

myArray.push({ id: 24, value: 246 });

In my case I needed the configuration stage to be blocking as a whole, but execute each role in parallel. I've tackled this issue using the following code:

echo webserver loadbalancer database | tr ' ' '\n' \
| xargs -I % -P 3 bash -c 'ansible-playbook $1.yml' -- %

the -P 3 argument in xargs makes sure that all the commands are ran in parallel, each command executes the respective playbook and the command as a whole blocks until all parts are finished.

If indeed the goal is to see if a string contains the actual space character (as described in the title), as opposed to any other sort of whitespace characters, you can use:

string s = "Hello There";
bool fHasSpace = s.Contains(" ");

If you're looking for ways to detect whitespace, there's several great options below.

Most likely these classes are already defined by Bootstrap, make sure that your CSS file that you want to override the classes with is called AFTER the Bootstrap CSS.

<link rel="stylesheet" href="css/bootstrap.css" /> <!-- Call Bootstrap first -->
<link rel="stylesheet" href="css/bootstrap-override.css" /> <!-- Call override CSS second -->

Otherwise, you can put !important at the end of your CSS like this: color:#ffffff!important; but I would advise against using !important at all costs.

That's not a jQuery object, it's just an object.

You can use the hasOwnProperty method to check for a key:

if (obj.hasOwnProperty("key1")) {
  ...
}

Dont forget to add user agent since some server will block request if there's no server agent..(you would get Forbidden resource response) example :

curl -X POST -A 'Mozilla/5.0 (X11; Linux x86_64; rv:30.0) Gecko/20100101 Firefox/30.0' -d "field=acaca&name=afadxx" https://example.com

Swift 4

let view = ...
let point = ...
view.bounds.contains(point)

Objective-C

Use CGRectContainsPoint():

bool CGRectContainsPoint(CGRect rect, CGPoint point);

Parameters

• rect The rectangle to examine.
• point The point to examine. Return Value true if the rectangle is not null or empty and the point is located within the rectangle; otherwise, false.

A point is considered inside the rectangle if its coordinates lie inside the rectangle or on the minimum X or minimum Y edge.

From time to time I present MR concepts to people. I find processing tasks familiar to people and then map them to the MR paradigm.

Usually I take two things:

1. Group By / Aggregations. Here the advantage of the shuffling stage is clear. An explanation that shuffling is also distributed sort + an explanation of distributed sort algorithm also helps.

2. Join of two tables. People working with DB are familiar with the concept and its scalability problem. Show how it can be done in MR.

It's possible you want overloading or default parameters - define the same function with defaulted parameters:

void doStuff( int a, double termstator = 1.0, bool useFlag = true )
{
   // stuff
}

void doStuff( double std_termstator )
{
   // assume the user always wants '1' for the a param
   return doStuff( 1, std_termstator );
}

This will allow you to call the method with one of four different calls:

doStuff( 1 );
doStuff( 2, 2.5 );
doStuff( 1, 1.0, false );
doStuff( 6.72 );

... or you could be looking for the v_args calling conventions from C.

UPDATE

I also tried this, but to no avail:

$(document).ready(function() {
$('body :not(.wr-dropdown)').bind("click", function(e) {
    $('.test').focus();
})
$('.wr-dropdown').on('change', function(e) {
    if ($(".wr-dropdow option[value='/search']")) {
        setTimeout(function(e) {
            $('body :not(.wr-dropdown)').trigger("click");
        },3000)         
    } 
}); 

});

I am confused as to why you say this isn't working because your JSFiddle is working just fine, but here is my suggestion anyway...

Try this line of code in your SetTimeOut function on your click event:

document.myInput.focus();

myInput correlates to the name attribute of the input tag.

<input name="myInput">

And use this code to blur the field:

document.activeElement.blur();

instead of using the == sign, more safer use the === sign when compare, the code that you post is work well

Try this code

add this override method to controller

protected override void OnActionExecuting(ActionExecutingContext actionExecutingContext)
{
   var actionName = actionExecutingContext.ActionDescriptor.ActionName;
   var controllerName = actionExecutingContext.ActionDescriptor.ControllerDescriptor.ControllerName;
   base.OnActionExecuting(actionExecutingContext);
}

Unfortunately, no approached mentioned here worked for me. I have to register couple PFX in a docker container and I need to pass the password via command line.

So I re-developed the sn.exe -i <infile> <container> command in C# using the RSACryptoServiceProvider. The source and the app are on GitHub in the SnInstallPfx project.

The SnInstallPfx app accepts a PFX key and its password. It computes the key container name (VS_KEY_*) automatically (borrowed from MSBuild source code) and installs it to the strong name CSP.

Usage:

SnInstallPfx.exe <pfx_infile> <pfx_password>
// or pass a container name if the default is not what you need (e.g. C++)
SnInstallPfx.exe <pfx_infile> <pfx_password> <container_name>

Sometimes it is very convenient to use stringstream to convert between strings and other numerical types. The usage of stringstream is similar to the usage of iostream, so it is not a burden to learn.

Stringstreams can be used to both read strings and write data into strings. It mainly functions with a string buffer, but without a real I/O channel.

The basic member functions of stringstream class are

• str(), which returns the contents of its buffer in string type.

• str(string), which set the contents of the buffer to the string argument.

Here is an example of how to use string streams.

ostringstream os;
os << "dec: " << 15 << " hex: " << std::hex << 15 << endl;
cout << os.str() << endl;

The result is dec: 15 hex: f.

istringstream is of more or less the same usage.

To summarize, stringstream is a convenient way to manipulate strings like an independent I/O device.

FYI, the inheritance relationships between the classes are:

Simple solution:

<style>
.center {
    margin: auto;

}
</style>

<div class="center">
    <p> somthing goes here </p>
</div>

You have 3 options: Chrome (via Developer Tools -> Network tab), Wireshark, and Fiddler (via Log tab), however they all very basic. If you have very high volume of traffic or each frame is very large, it becomes very difficult to use them for debugging.

You can however use Fiddler with FiddlerScript to inspect WebSocket traffic in the same way you inpect HTTP traffic. Few advantages of this solution are that you can leverage many other functionalities in Fiddler, such as multiple inspectors (HexView, JSON, SyntaxView), compare packets, and find packets, etc.

Please refer to my recently written article on CodeProject, which show you how to Debug/Inspect WebSocket traffic with Fiddler (with FiddlerScript). http://www.codeproject.com/Articles/718660/Debug-Inspect-WebSocket-traffic-with-Fiddler

In my case, "Sept8" in a csv file generated using R was converted into "8-Sept" by Excel 2013. The problem was solved by using write.xlsx2() function in the xlsx package to generate the output file in xlsx format, which can be loaded by Excel without unwanted conversion. So, if you are given a csv file, you can try loading it into R and converting it into xlsx using the write.xlsx2() function.

The difference can be illustrated by the following:

std::cout << std::endl;

is equivalent to

std::cout << '\n' << std::flush;

So,

• Use std::endl If you want to force an immediate flush to the output.
• Use \n if you are worried about performance (which is probably not the case if you are using the << operator).

I use \n on most lines.
Then use std::endl at the end of a paragraph (but that is just a habit and not usually necessary).

Contrary to other claims, the \n character is mapped to the correct platform end of line sequence only if the stream is going to a file (std::cin and std::cout being special but still files (or file-like)).

Indeed, as has been mentioned above (and elsewhere on SO), in order to convert the string to a date, you need a specific date of the month. From the as.Date() manual page:

If the date string does not specify the date completely, the returned answer may be system-specific. The most common behaviour is to assume that a missing year, month or day is the current one. If it specifies a date incorrectly, reliable implementations will give an error and the date is reported as NA. Unfortunately some common implementations (such as glibc) are unreliable and guess at the intended meaning.

A simple solution would be to paste the date "01" to each date and use strptime() to indicate it as the first day of that month.

For those seeking a little more background on processing dates and times in R:

In R, times use POSIXct and POSIXlt classes and dates use the Date class.

Dates are stored as the number of days since January 1st, 1970 and times are stored as the number of seconds since January 1st, 1970.

So, for example:

d <- as.Date("1971-01-01")
unclass(d)  # one year after 1970-01-01
# [1] 365

pct <- Sys.time()  # in POSIXct
unclass(pct)  # number of seconds since 1970-01-01
# [1] 1450276559
plt <- as.POSIXlt(pct)
up <- unclass(plt)  # up is now a list containing the components of time
names(up)
# [1] "sec"    "min"    "hour"   "mday"   "mon"    "year"   "wday"   "yday"   "isdst"  "zone"  
# [11] "gmtoff"
up$hour
# [1] 9

To perform operations on dates and times:

plt - as.POSIXlt(d)
# Time difference of 16420.61 days

And to process dates, you can use strptime() (borrowing these examples from the manual page):

strptime("20/2/06 11:16:16.683", "%d/%m/%y %H:%M:%OS")
# [1] "2006-02-20 11:16:16 EST"

# And in vectorized form:
dates <- c("1jan1960", "2jan1960", "31mar1960", "30jul1960")
strptime(dates, "%d%b%Y")
# [1] "1960-01-01 EST" "1960-01-02 EST" "1960-03-31 EST" "1960-07-30 EDT"

If you are considering creating a function, try this: DECLARE @schema sysname = 'dbo' , @tablename sysname = 'mvtEST' , @cmd NVarchar(2000) , @ColName sysname

    DECLARE @NewLine Table
    (ColumnName Varchar(100)
    ,Location Int
    ,ColumnValue Varchar(8000)
    )

    SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE  TABLE_SCHEMA = @schema AND TABLE_NAME =  @tablename AND DATA_TYPE LIKE '%CHAR%'

    DECLARE looper CURSOR FAST_FORWARD for
    SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = @schema AND TABLE_NAME =  @tablename AND DATA_TYPE LIKE '%CHAR%'
    OPEN looper
    FETCH NEXT FROM looper INTO @ColName

    WHILE @@fetch_status = 0
    BEGIN
    SELECT @cmd = 'select ''' +@ColName+    ''',  CHARINDEX(Char(10),  '+  @ColName +') , '+ @ColName + ' from '+@schema + '.'+@tablename +' where CHARINDEX(Char(10),  '+  @ColName +' ) > 0 or CHARINDEX(CHAR(13), '+@ColName +') > 0'
    PRINT @cmd
    INSERT @NewLine ( ColumnName, Location, ColumnValue )
    EXEC sp_executesql @cmd
    FETCH NEXT FROM looper INTO @ColName
    end
    CLOSE looper
    DEALLOCATE looper


    SELECT * FROM  @NewLine

To run a command as root, and pass it the password at the command prompt, you could do it as so:

import subprocess
from getpass import getpass

ls = "sudo -S ls -al".split()
cmd = subprocess.run(
    ls, stdout=subprocess.PIPE, input=getpass("password: "), encoding="ascii",
)
print(cmd.stdout)

For your example, probably something like this:

import subprocess
from getpass import getpass

restart_apache = "sudo /usr/sbin/apache2ctl restart".split()
proc = subprocess.run(
    restart_apache,
    stdout=subprocess.PIPE,
    input=getpass("password: "),
    encoding="ascii",
)

It's programmer preference. Personally, I love using this since it explicitly marks the object members. Of course the _ does the same thing (only when you follow the convention)

You can use Dialog to create this easily

create a Dialog instance using the context

Dialog dialog = new Dialog(contex);

You can design your layout as you like.

You can add this layout to your dialog by dialog.setContentView(R.layout.popupview);//popup view is the layout you created

then you can access its content (textviews, etc.) by using findViewById method

TextView txt = (TextView)dialog.findViewById(R.id.textbox);

you can add any text here. the text can be stored in the String.xml file in res\values.

txt.setText(getString(R.string.message));

then finally show the pop up menu

dialog.show();

In C++11 you can use std::to_string:

#include <string>

std::string s = std::to_string(5);

If you're working with prior to C++11, you could use C++ streams:

#include <sstream>

int i = 5;
std::string s;
std::stringstream out;
out << i;
s = out.str();

As it turns out, my suspicions were right. The audience aud claim in a JWT is meant to refer to the Resource Servers that should accept the token.

As this post simply puts it:

The audience of a token is the intended recipient of the token.

The audience value is a string -- typically, the base address of the resource being accessed, such as https://contoso.com.

The client_id in OAuth refers to the client application that will be requesting resources from the Resource Server.

The Client app (e.g. your iOS app) will request a JWT from your Authentication Server. In doing so, it passes it's client_id and client_secret along with any user credentials that may be required. The Authorization Server validates the client using the client_id and client_secret and returns a JWT.

The JWT will contain an aud claim that specifies which Resource Servers the JWT is valid for. If the aud contains www.myfunwebapp.com, but the client app tries to use the JWT on www.supersecretwebapp.com, then access will be denied because that Resource Server will see that the JWT was not meant for it.

Warning: Only one null row can be in the column you've set to be unique.

You can do this with a filtered index in SQL 2008:

CREATE UNIQUE NONCLUSTERED INDEX idx_col1
ON dbo.MyTable(col1)
WHERE col1 IS NOT NULL;

See Field value must be unique unless it is NULL for a range of answers.

This is the shortest I could get using Core Java.

List<Integer> makeSequence(int begin, int end) {
  List<Integer> ret = new ArrayList(end - begin + 1);

  for(int i = begin; i <= end; i++, ret.add(i));

  return ret;  
}

Different binary trees with n nodes:

(1/(n+1))*(2nCn)

where C=combination eg.

n=6,
possible binary trees=(1/7)*(12C6)=132

The easiest way to do that would be to use the Params plugin, introduced in beta5. It has utility methods to make it easy to access different types of parameters. As always, reading the tests can prove valuable to understand how something is supposed to be used.

Get a single value

To get the value of a named parameter in a controller, you will need to select the appropriate method for the type of parameter you are looking for and pass in the name.

Examples:

$this->params()->fromPost('paramname');   // From POST
$this->params()->fromQuery('paramname');  // From GET
$this->params()->fromRoute('paramname');  // From RouteMatch
$this->params()->fromHeader('paramname'); // From header
$this->params()->fromFiles('paramname');  // From file being uploaded

Default values

All of these methods also support default values that will be returned if no parameter with the given name is found.

Example:

$orderBy = $this->params()->fromQuery('orderby', 'name');

When visiting http://example.com/?orderby=birthdate, $orderBy will have the value birthdate.
When visiting http://example.com/, $orderBy will have the default value name.
 

Get all parameters

To get all parameters of one type, just don't pass in anything and the Params plugin will return an array of values with their names as keys.

Example:

$allGetValues = $this->params()->fromQuery(); // empty method call

When visiting http://example.com/?orderby=birthdate&filter=hasphone $allGetValues will be an array like

array(
    'orderby' => 'birthdate',
    'filter'  => 'hasphone',
);

Not using Params plugin

If you check the source code for the Params plugin, you will see that it's just a thin wrapper around other controllers to allow for more consistent parameter retrieval. If you for some reason want/need to access them directly, you can see in the source code how it's done.

Example:

$this->getRequest()->getRequest('name', 'default');
$this->getEvent()->getRouteMatch()->getParam('name', 'default');

NOTE: You could have used the superglobals $_GET, $_POST etc., but that is discouraged.

I don't think you should use the data option, because this does more than just setting a default value. You're also overriding any data that's being passed to the form during creation. So basically, you're breaking support for that feature. - Which might not matter when you're letting the user create data, but does matter when you want to (someday) use the form for updating data.

See http://symfony.com/doc/current/reference/forms/types/choice.html#data

I believe it would be better to pass any default data during form creation. In the controller.

For example, you can pass in a class and define the default value in your class itself. (when using the default Symfony\Bundle\FrameworkBundle\Controller\Controller)

$form = $this->createForm(AnimalType::class, [
    'species' => 174 // this id might be substituted by an entity
]);

Or when using objects:

$dog = new Dog();
$dog->setSpecies(174); // this id might be substituted by an entity

$form = $this->createForm(AnimalType::class, $dog);

Even better when using a factory: (where dog probably extends from animal)

$form = $this->createForm(AnimalType::class, DogFactory::create());

This will enable you to separate form structure and content from each other and make your form reusable in more situations.

Or, use the preferred_choices option, but this has the side effect of moving the default option to the top of your form.

See: http://symfony.com/doc/current/reference/forms/types/choice.html#preferred-choices

$builder->add(
    'species', 
    'entity', 
    [
        'class' => 'BFPEduBundle:Item',
        'property' => 'name',
        'query_builder' => ...,
        'preferred_choices' => [174] // this id might be substituted by an entity
     ]
 );

Josh is correct but he left out one variation:

ALTER ROLE <role_name> IN DATABASE <db_name> SET search_path TO schema1,schema2;

Set the search path for the user, in one particular database.

$(document).ready(function () {
    $('#tags').on('change', function () {
        $('#tagsname').html('You selected: ' + this.value);
    }).change();
    $('#tags').on('blur', function (e, ui) {
        $('#tagsname').html('You selected: ' + ui.item.value);
    });
});

I guess the method std:remove works but it was giving some compatibility issue with the includes so I ended up writing this little function:

string removeCharsFromString(const string str, char* charsToRemove )
{
    char c[str.length()+1]; // + terminating char
    const char *p = str.c_str();
    unsigned int z=0, size = str.length();
    unsigned int x;
    bool rem=false;

    for(x=0; x<size; x++)
    {
        rem = false;
        for (unsigned int i = 0; charsToRemove[i] != 0; i++)
        {
            if (charsToRemove[i] == p[x])
            {
                rem = true;
                break;
            }
        }
        if (rem == false) c[z++] = p[x];
    }

    c[z] = '\0';
    return string(c);
}

Just use as

myString = removeCharsFromString(myString, "abc\r");

and it will remove all the occurrence of the given char list.

This might also be a bit more efficient as the loop returns after the first match, so we actually do less comparison.

Add a literal space, or a tab:

public void displayCustomerInfo() {
    System.out.println(Name + " " + Income);

    // or a tab
    System.out.println(Name + "\t" + Income);
}

Rethrowing exceptions via throw is useful when you don't have a particular code to handle current exceptions, or in cases when you have a logic to handle specific error cases but want to skip all others.

Example:

string numberText = "";
try
{
    Console.Write("Enter an integer: ");
    numberText = Console.ReadLine();
    var result = int.Parse(numberText);

    Console.WriteLine("You entered {0}", result);
}
catch (FormatException)
{
    if (numberText.ToLowerInvariant() == "nothing")
    {
        Console.WriteLine("Please, please don't be lazy and enter a valid number next time.");
    }
    else
    {
        throw;
    }
}    
finally
{
    Console.WriteLine("Freed some resources.");
}
Console.ReadKey();

However, there is also another way of doing this, using conditional clauses in catch blocks:

string numberText = "";
try
{
    Console.Write("Enter an integer: ");
    numberText = Console.ReadLine();
    var result = int.Parse(numberText);

    Console.WriteLine("You entered {0}", result);
}
catch (FormatException) when (numberText.ToLowerInvariant() == "nothing")
{
    Console.WriteLine("Please, please don't be lazy and enter a valid number next time.");
}    
finally
{
    Console.WriteLine("Freed some resources.");
}
Console.ReadKey();

This mechanism is more efficient than re-throwing an exception because of the .NET runtime doesn’t have to rebuild the exception object before re-throwing it.

The easiest way is to just learn how to do DOM traversing and manipulation with the plain DOM api (you would probably call this: normal JavaScript).

This can however be a pain for some things. (which is why libraries were invented in the first place).

Googling for "javascript DOM traversing/manipulation" should present you with plenty of helpful (and some less helpful) resources.

The articles on this website are pretty good: http://www.htmlgoodies.com/primers/jsp/

And as Nosredna points out in the comments: be sure to test in all browsers, because now jQuery won't be handling the inconsistencies for you.

This can also occur when the path ends in a '' followed by the closing quotation mark. e.g. The following line is passed as one of the arguments and this is not right:

"c:\users\abc\"

instead pass that argument as shown below so that the last backslash is escaped instead of escaping the quotation mark.

"c:\users\abc\\"

You can create external command Run -> External Tools -> External Tools Configuration...

It will be available under Run -> External Tools and can be run using shortcuts.

This should be close to what you are looking for your first example:

=SUM(INDIRECT("A1:A"&B1,TRUE))

This should be close to what you are looking for your final example:

=SUM(INDIRECT("A"&1+B1&":A"&B1,TRUE))

Here is an update for Swift 3 and an addition to Mani's answer. I would suggest using sender.view in combination with tagging UIViews (or other elements, depending on what you are trying to track) for a somewhat more "advanced" approach.

1. Adding the UITapGestureRecognizer to e.g. an UIButton (you can add this to UIViews etc. as well) Or a whole bunch of items in an array with a for-loop and a second array for the tap gestures.

    let yourTapEvent = UITapGestureRecognizer(target: self, action: #selector(yourController.yourFunction)) 
    yourObject.addGestureRecognizer(yourTapEvent) // adding the gesture to your object

2. Defining the function in the same testController (that's the name of your View Controller). We are going to use tags here - tags are Int IDs, which you can add to your UIView with yourButton.tag = 1. If you have a dynamic list of elements like an array you can make a for-loop, which iterates through your array and adds a tag, which increases incrementally

   func yourFunction(_ sender: AnyObject) {
       let yourTag = sender.view!.tag // this is the tag of your gesture's object
       // do whatever you want from here :) e.g. if you have an array of buttons instead of just 1:
       for button in buttonsArray {
         if(button.tag == yourTag) {
           // do something with your button
         }
       }
   }
   

The reason for all of this is because you cannot pass further arguments for yourFunction when using it in conjunction with #selector.

If you have an even more complex UI structure and you want to get the parent's tag of the item attached to your tap gesture you can use let yourAdvancedTag = sender.view!.superview?.tag e.g. getting the UIView's tag of a pressed button inside that UIView; can be useful for thumbnail+button lists etc.
