[0-9] is not always equivalent to \d. In python3, [0-9] matches only 0123456789 characters, while \d matches [0-9] and other digit characters, for example Eastern Arabic numerals ??????????.

It's really not that big of a deal. You could just make a script with the single command:

chmod a+x *.pl

And run the script after creating a perl file. Alternatively, you could open a file with a command like this:

touch filename.pl && chmod a+x filename.pl && vi filename.pl # choose your favorite editor

This is easily achieved in ES6;

You can convert strings to Arrays with Array.from('string');

Array.from("01")

will console.log

['0', '1']

Which is exactly what you're looking for.

Here a solution that does not use eval, and works with scripts, linked scripts , as well as with modules.

The function accepts 3 parameters :

• html : String with the html code to insert
• dest : reference to the target element
• append : boolean flag to enable appending at the end of the target element html

function insertHTML(html, dest, append=false){
    // if no append is requested, clear the target element
    if(!append) dest.innerHTML = '';
    // create a temporary container and insert provided HTML code
    let container = document.createElement('div');
    container.innerHTML = html;
    // cache a reference to all the scripts in the container
    let scripts = container.querySelectorAll('script');
    // get all child elements and clone them in the target element
    let nodes = container.childNodes;
    for( let i=0; i< nodes.length; i++) dest.appendChild( nodes[i].cloneNode(true) );
    // force the found scripts to execute...
    for( let i=0; i< scripts.length; i++){
        let script = document.createElement('script');
        script.type = scripts[i].type || 'text/javascript';
        if( scripts[i].hasAttribute('src') ) script.src = scripts[i].src;
        script.innerHTML = scripts[i].innerHTML;
        document.head.appendChild(script);
        document.head.removeChild(script);
    }
    // done!
    return true;
}

The function combn is in the standard utils package (i.e. already installed)

choose is also already available in the Special {base}

Please note , you might need to disable adblocks if necessary. Drag and drop off script path in visual studio doesn't work if you are using HTML pages but it does work for mvc ,asp.netwebforms. I figured this after one hour

Change the backend to automatic:

Tools > preferences > IPython console > Graphics > Graphics backend > Backend: Automatic

Then close and open Spyder.

With user defined functions, you have to declare every parameter, even if they have a default value.

The following would execute successfully:

IF dbo.CheckIfSFExists( 23, default ) = 0
    SET @retValue = 'bla bla bla;

Great answers, but if you look for a singe line do all, you can concatenate, alias and enjoy the convenience:

git add * && git commit -am "<commit message>"

It is a single line but two commands, and as mentioned you can alias these commands:

alias git-aac="git add * && git commit -am " (the space at the end is important) because you are going to parameterize the new short hand command.

From this moment on, you will be using this alias:

git-acc "<commit message>"

You basically say:

git, add for me all untracked files and commit them with this given commit message.

Hope you use Linux, hope this helps.

This is how I solved it:

void selectPage(int pageIndex){
    tabLayout.setScrollPosition(pageIndex,0f,true);
    viewPager.setCurrentItem(pageIndex);
}

Try this

$('.slidingDiv').toggle("slide", {direction: "right" }, 1000);

The example code above was really helpful to me, however (as has been hinted at above), I think you need to use NSMutableURLRequest rather than NSURLRequest. In its current form, I couldn't get it to respond to the setHTTPMethod call. Changing the type fixed things right up.

You could put a crontab file in /etc/cron.d which would run a script that would run your command and then delete the crontab file in /etc/cron.d. Of course, that means your script would need to run as root.

Pure speculation is that you're using a terminal that attempts to do word-wrapping rather than character-wrapping, and treats B as a word character but # as a non-word character. So when it reaches the end of a line and searches for a place to break the line, it sees a # almost immediately and happily breaks there; whereas with the B, it has to keep searching for longer, and may have more text to wrap (which may be expensive on some terminals, e.g., outputting backspaces, then outputting spaces to overwrite the letters being wrapped).

But that's pure speculation.

This one worked for me (it seems like they changed the button classname or id) :

function ClickConnect(){_x000D_
    console.log("Working"); _x000D_
    document.querySelector("colab-connect-button").click() _x000D_
}_x000D_
setInterval(ClickConnect,60000)

Usage:

sftp("file:/C:/home/file.txt", "ssh://user:pass@host/home");
sftp("ssh://user:pass@host/home/file.txt", "file:/C:/home");

Implementation

TL;DR: Use the utility method Iterables.size(Iterable) of the great Guava library.

Of your two code snippets, you should use the first one, because the second one will remove all elements from values, so it is empty afterwards. Changing a data structure for a simple query like its size is very unexpected.

For performance, this depends on your data structure. If it is for example in fact an ArrayList, removing elements from the beginning (what your second method is doing) is very slow (calculating the size becomes O(n*n) instead of O(n) as it should be).

In general, if there is the chance that values is actually a Collection and not only an Iterable, check this and call size() in case:

if (values instanceof Collection<?>) {
  return ((Collection<?>)values).size();
}
// use Iterator here...

The call to size() will usually be much faster than counting the number of elements, and this trick is exactly what Iterables.size(Iterable) of Guava does for you.

lets put this in a simple term. An element is a set of opening and closing tags in use.

Element

<h1>...</h1>

Tag H1 opening tag

<h1>

H1 closing tag

</h1>

I wrote this up the other day

#! /usr/bin/env python

class Node(object):
    def __init__(self):
        self.data = None # contains the data
        self.next = None # contains the reference to the next node


class LinkedList:
    def __init__(self):
        self.cur_node = None

    def add_node(self, data):
        new_node = Node() # create a new node
        new_node.data = data
        new_node.next = self.cur_node # link the new node to the 'previous' node.
        self.cur_node = new_node #  set the current node to the new one.

    def list_print(self):
        node = self.cur_node # cant point to ll!
        while node:
            print node.data
            node = node.next



ll = LinkedList()
ll.add_node(1)
ll.add_node(2)
ll.add_node(3)

ll.list_print()

Don't use the alias (P) in your WHERE clause directly.

You can either use the same REPLACE logic again in the WHERE clause:

SELECT Replace(Postcode, ' ', '') AS P
FROM Contacts
WHERE Replace(Postcode, ' ', '') LIKE 'NW101%'

Or use an aliased sub query as described in Nick's answers.

Open the file again using vi. and then press " i " or press insert key ,

For save and quit

  Enter Esc    

and write the following command

  :wq

without save and quit

  :q!

This won't be suitable for everyone, but if your application is already setup to take commands via a socket, you can use netcat to issue a commands via cron proper.

echo 'mycommand' | nc -U /tmp/myapp.sock

I had a similar issue not long time ago and this was how I solved it

.rotated-half-circle {_x000D_
  /* Create the circle */_x000D_
  width: 40px;_x000D_
  height: 40px;_x000D_

  border-radius: 50%;_x000D_
  /* Halve the circle */_x000D_
  border-bottom-color: transparent;_x000D_
  border-left-color: transparent;_x000D_
  /* Rotate the circle */_x000D_
  transform: rotate(-45deg);_x000D_
}

<div class="rotated-half-circle"></div>

In PowerShell v3, have a look at the Invoke-WebRequest and Invoke-RestMethod e.g.:

$msg = Read-Host -Prompt "Enter message"
$encmsg = [System.Web.HttpUtility]::UrlEncode($msg)
Invoke-WebRequest -Uri "http://smsserver/SNSManager/msgSend.jsp?uid&to=smartsms:*+001XXXXXX&msg=$encmsg&encoding=windows-1255"

This is one of those things that can be difficult to search for if you don't already know where to look.

[ is actually a command, not part of the bash shell syntax as you might expect. It happens to be a Bash built-in command, so it's documented in the Bash manual.

There's also an external command that does the same thing; on many systems, it's provided by the GNU Coreutils package.

[ is equivalent to the test command, except that [ requires ] as its last argument, and test does not.

Assuming the bash documentation is installed on your system, if you type info bash and search for 'test' or '[' (the apostrophes are part of the search), you'll find the documentation for the [ command, also known as the test command. If you use man bash instead of info bash, search for ^ *test (the word test at the beginning of a line, following some number of spaces).

Following the reference to "Bash Conditional Expressions" will lead you to the description of -ne, which is the numeric inequality operator ("ne" stands for "not equal). By contrast, != is the string inequality operator.

You can also find bash documentation on the web.

• Bash reference
• Bourne shell builtins (including test and [)
• Bash Conditional Expressions -- (Scroll to the bottom; -ne is under "arg1 OP arg2")
• POSIX documentation for test

The official definition of the test command is the POSIX standard (to which the bash implementation should conform reasonably well, perhaps with some extensions).

Well, there's nothing really that can pass through that, other than % wildcard. It could be dangerous if you were using LIKE statement as attacker could put just % as login if you don't filter that out, and would have to just bruteforce a password of any of your users. People often suggest using prepared statements to make it 100% safe, as data can't interfere with the query itself that way. But for such simple queries it probably would be more efficient to do something like $login = preg_replace('/[^a-zA-Z0-9_]/', '', $login);

If it's written in .NET and compiled to CIL, it can be reflected. If security is a concern and obfuscation is to be avoided, then I recommend writing your application using a non-managed language, which is, by nature, harder to reverse engineer.

With Hooks and useState

Use defaultValue to select the default value.

    const statusOptions = [
        { value: 1, label: 'Publish' },
        { value: 0, label: 'Unpublish' }
    ];
    const [statusValue, setStatusValue] = useState('');
    const handleStatusChange = e => {
        setStatusValue(e.value);
    }

return(
<>
<Select options={statusOptions} 
    defaultValue={[{ value: published, label: published == 1 ? 'Publish' : 'Unpublish' }]} 
    onChange={handleStatusChange} 
    value={statusOptions.find(obj => obj.value === statusValue)} required />
</>
)

You need to treat a table valued udf like a table, eg JOIN it

select Emp_Id 
from Employee E JOIN dbo.Splitfn(@Id,',') CSV ON E.Emp_Id = CSV.items 

It looks like the test is waiting for some callback that never comes. It's likely because the test is not executed with asynchronous behavior.

First, see if just using fakeAsync in your "it" scenario:

it('should do something', fakeAsync(() => {

You can also use flush() to wait for the microTask queue to finish or tick() to wait a specified amount of time.

Here is an alternative way of doing this using the not in operator:

# define an empty dict
years_dict = dict()

for line in list:
    # here define what key is, for example,
    key = line[0]
    # check if key is already present in dict
    if key not in years_dict:
        years_dict[key] = []
    # append some value 
    years_dict[key].append(some.value)

A lot of the answers here are great. But I wanted something a little simpler. I wanted something that will work with the "Hello World" sample for free. This means I wanted a simple produces a request body that matches the query string:

{
#foreach($param in $input.params().querystring.keySet())
  "$param": "$util.escapeJavaScript($input.params().querystring.get($param))" #if($foreach.hasNext),#end
#end
}

I think the top answer produces something more useful when building something real, but for getting a quick hello world running using the template from AWS this works great.

The Python docs for hash() state:

Hash values are integers. They are used to quickly compare dictionary keys during a dictionary lookup.

Python dictionaries are implemented as hash tables. So any time you use a dictionary, hash() is called on the keys that you pass in for assignment, or look-up.

Additionally, the docs for the dict type state:

Values that are not hashable, that is, values containing lists, dictionaries or other mutable types (that are compared by value rather than by object identity) may not be used as keys.

Since you're using formatters for the rest of it, just use DecimalFormat:

import java.text.DecimalFormat;

DecimalFormat xFormat = new DecimalFormat("000")
System.out.print(xFormat.format(x + 1) + " ");

Alternative you could do whole job in whole line using printf:

System.out.printf("%03d %s  %s    %s    \n",  x + 1, // the payment number
formatter.format(monthlyInterest),  // round our interest rate
formatter.format(principleAmt),
formatter.format(remainderAmt));

Every time you get this kind of error

bash: <command>: command not found

• On a host with that command already working with this solution:

  dpkg -S $(which <command>)
  

• Don't have a host with that package installed? Try this:

  apt-file search /bin/<command>
  

using (StreamWriter writer = File.AppendText(LoggingPath))
{
    writer.WriteLine("Text");
}

u want select all data from database then u can try this:-

dbclassDataContext dc= new dbclassDataContext()
List<tableName> ObjectName= dc.tableName.ToList();

otherwise You can try this:-

var Registration = from reg in dcdc.GetTable<registration>() select reg;

and method Syntex :-

 var Registration = dc.registration.Select(reg => reg); 

I appreciate this is an old question now but my solution wasn't an answer on here so posting it in case anyone else tries all the rest.

In my case, a previous install of the Java JRE (in ProgramData/Oracle/Java) had a path variable at the top of my list of path variables. The contents of that "Oracle" path had a java.exe but not a javac.exe. I added my full JDK path to the top of the list of path variables, ahead of the "Oracle" one, and it then picked up javac.exe as well as java.

Hope that you're affected with build.gradle(app) If do so , follow this step

Replace compile with androidTestImplementation in build.gradle

androidTestImplementation 'com.android.support:appcompat-v7:27.1.1'
androidTestImplementation 'com.android.support:design:27.1.1'

so simple ! hope this will solve

range() can only work with integers, but dividing with the / operator always results in a float value:

>>> 450 / 10
45.0
>>> range(450 / 10)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'float' object cannot be interpreted as an integer

Make the value an integer again:

for i in range(int(c / 10)):

or use the // floor division operator:

for i in range(c // 10):

I attempted to find a more elegant solution, but the best I could do was basically the same thing that Dyno Fu said:

from copy import copy

def subtract_lists(a, b):
    """
    >>> a = [0, 1, 2, 1, 0]
    >>> b = [0, 1, 1]
    >>> subtract_lists(a, b)
    [2, 0]

    >>> import random
    >>> size = 10000
    >>> a = [random.randrange(100) for _ in range(size)]
    >>> b = [random.randrange(100) for _ in range(size)]
    >>> c = subtract_lists(a, b)
    >>> assert all((x in a) for x in c)
    """
    a = copy(a)
    for x in b:
        if x in a:
            a.remove(x)
    return a

From the RFC (3023), under section 3, XML Media Types:

If an XML document -- that is, the unprocessed, source XML document -- is readable by casual users, text/xml is preferable to application/xml. MIME user agents (and web user agents) that do not have explicit support for text/xml will treat it as text/plain, for example, by displaying the XML MIME entity as plain text. Application/xml is preferable when the XML MIME entity is unreadable by casual users.

(emphasis mine)

The syntax is wrong. A member pointer is a different type category from a ordinary pointer. The member pointer will have to be used together with an object of its class:

class A {
public:
 int f();
 int (A::*x)(); // <- declare by saying what class it is a pointer to
};

int A::f() {
 return 1;
}


int main() {
 A a;
 a.x = &A::f; // use the :: syntax
 printf("%d\n",(a.*(a.x))()); // use together with an object of its class
}

a.x does not yet say on what object the function is to be called on. It just says that you want to use the pointer stored in the object a. Prepending a another time as the left operand to the .* operator will tell the compiler on what object to call the function on.

I had the same problem and solved it with:

Code:

$.fn.nextNode = function(){
  var contents = $(this).parent().contents();
  return contents.get(contents.index(this)+1);
}

Usage:

$('#my_id').nextNode();

Is like next() but also returns the text nodes.

The answer of 'ChrisG' is correct, but we need to refresh MainWindowTitle every time and it's better to check for empty.... like this:

var proc = Process.Start("popup.exe");
while (string.IsNullOrEmpty(proc.MainWindowTitle))
{
    System.Threading.Thread.Sleep(100);
    proc.Refresh();
}

This shows the number of connections per each DB:

SELECT 
    DB_NAME(dbid) as DBName, 
    COUNT(dbid) as NumberOfConnections,
    loginame as LoginName
FROM
    sys.sysprocesses
WHERE 
    dbid > 0
GROUP BY 
    dbid, loginame

And this gives the total:

SELECT 
    COUNT(dbid) as TotalConnections
FROM
    sys.sysprocesses
WHERE 
    dbid > 0

If you need more detail, run:

sp_who2 'Active'

Note: The SQL Server account used needs the 'sysadmin' role (otherwise it will just show a single row and a count of 1 as the result)

You can create functions in react components. It is actually regular ES6 class which inherits from React.Component. Just be careful and bind it to the correct context in onClick event:

export default class Archive extends React.Component { 

    saySomething(something) {
        console.log(something);
    }

    handleClick(e) {
        this.saySomething("element clicked");
    }

    componentDidMount() {
        this.saySomething("component did mount");
    }

    render() {
        return <button onClick={this.handleClick.bind(this)} value="Click me" />;
    }
}

This is sort of coming at the question from the other end but I thought I'd throw it in as I really had to dig on the internet to find this out.

There is a lot of stuff about how to check roles but not much saying what you are actually checking when you say hasRole("blah")

HasRole checks the granted authorities for the currently authenticated principal

So really when you see hasRole("blah") really means hasAuthority("blah").

In the case I've seen, you do this with a class that Implements UserDetails which defines a method called getAuthorities. In this you'll basically add some new SimpleGrantedAuthority("some name") to a list based on some logic. The names in this list are the things checked by the hasRole statements.

I guess in this context the UserDetails object is the currently authenticated principal. There's some magic that happens in and around authentication providers and more specifically the authentication-manager that makes this happen.

You need to specify the path where your chromedriver is located.

1. Download chromedriver for your desired platform from here.

2. Place chromedriver on your system path, or where your code is.

3. If not using a system path, link your chromedriver.exe (For non-Windows users, it's just called chromedriver):

   browser = webdriver.Chrome(executable_path=r"C:\path\to\chromedriver.exe")
   

   (Set executable_path to the location where your chromedriver is located.)

   If you've placed chromedriver on your System Path, you can shortcut by just doing the following:

   browser = webdriver.Chrome()

4. If you're running on a Unix-based operating system, you may need to update the permissions of chromedriver after downloading it in order to make it executable:

   chmod +x chromedriver

5. That's all. If you're still experiencing issues, more info can be found on this other StackOverflow article: Can't use chrome driver for Selenium

None of these answers quite fit the problem i had as the migration i wanted to delete was missing: I had created and run a migration in some other branch, which was then discarded. The problem is when a migration is run, rails adds the version into a schema_migrations table in the database. So even if it isn't listed in your db structure or schema, rails looks for it. You can reveal these orphaned migrations by running:

rails db:migrate:status

Note the versions of the missing migrations and head into the db console:

rails dbconsole

Now remove the versions from the migration table manually:

delete from schema_migrations where version='<version>';

You should now be good.

forceUpdate(); method will work but it is advisable to use setState();

Since R is already installed, you should be able to upgrade it with this method. First of all, you may want to have the packages you installed in the previous version in the new one,so it is convenient to check this post. Then, follow the instructions from here

1. Open the sources.list file:

    sudo nano /etc/apt/sources.list    
   

2. Add a line with the source from where the packages will be retrieved. For example:

    deb https://cloud.r-project.org/bin/linux/ubuntu/ version/
   

   Replace https://cloud.r-project.org with whatever mirror you would like to use, and replace version/ with whatever version of Ubuntu you are using (eg, trusty/, xenial/, and so on). If you're getting a "Malformed line error", check to see if you have a space between /ubuntu/ and version/.

3. Fetch the secure APT key:

    gpg --keyserver keyserver.ubuntu.com --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9
   

or

    gpg --hkp://keyserver keyserver.ubuntu.com:80 --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9

4. Add it to keyring:

    gpg -a --export E084DAB9 | sudo apt-key add -
   

5. Update your sources and upgrade your installation:

    sudo apt-get update && sudo apt-get upgrade
   

6. Install the new version

    sudo apt-get install r-base-dev
   

7. Recover your old packages following the solution that best suits to you (see this). For instance, to recover all the packages (not only those from CRAN) the idea is:

-- copy the packages from R-oldversion/library to R-newversion/library, (do not overwrite a package if it already exists in the new version!).

-- Run the R command update.packages(checkBuilt=TRUE, ask=FALSE).

All your problems are that you are mixing content type negotiation with parameter passing. They are things at different levels. More specific, for your question 2, you constructed the response header with the media type your want to return. The actual content negotiation is based on the accept media type in your request header, not response header. At the point the execution reaches the implementation of the method getPersonFormat, I am not sure whether the content negotiation has been done or not. Depends on the implementation. If not and you want to make the thing work, you can overwrite the request header accept type with what you want to return.

return new ResponseEntity<>(PersonFactory.createPerson(), httpHeaders, HttpStatus.OK);

You can try with method select

DataRow[] rows = table.Select("ID = 7");

Hi Just addition to VonC comments. I am using ecj compiler to compile my project. it was throwing expcetion that some of the classes are not found. But the project was bulding fine with javac compiler.

So just I added the classes into the classpath(which we have to pass as argument) and now its working fine... :)

Kulbir Singh

Luckily, Python has this built-in :)

import re
re.split('; |, ',str)

Update:
Following your comment:

>>> a='Beautiful, is; better*than\nugly'
>>> import re
>>> re.split('; |, |\*|\n',a)
['Beautiful', 'is', 'better', 'than', 'ugly']

This worked for me:

np_arr = torch_tensor.cpu().detach().numpy()

You're looking for Action<T>, which takes a parameter.

Once you have cloned the repo, you have everything: you can then hg up branchname or hg up tagname to update your working copy.

UP: hg up is a shortcut of hg update, which also has hg checkout alias for people with git habits.

In simple words (mainly for newbie in coding), we can say,

    `return`: exits the function,
    `exit()`: exits the program (called as process while running)

Also if you observed, this is very basic, but...,

    `return`: is the keyword
    `exit()`: is the function

In my particular case, I had a similar error on a legacy website used in my organization. To solve the issue, I had to list the website a a "Trusted site".

To do so:

• Click the Tools button, and then Internet options.
• Go on the Security tab.
• Click on Trusted sites and then on the sites button.
• Enter the url of the website and click on Add.

I'm leaving this here in the remote case it will help someone.

In Ruby, the Windows version anyways, I just checked and __FILE__ does not contain the full path to the file. Instead it contains the path to the file relative to where it's being executed from.

In PHP __FILE__ is the full path (which in my opinion is preferable). This is why, in order to make your paths portable in Ruby, you really need to use this:

File.expand_path(File.dirname(__FILE__) + "relative/path/to/file")

I should note that in Ruby 1.9.1 __FILE__ contains the full path to the file, the above description was for when I used Ruby 1.8.7.

In order to be compatible with both Ruby 1.8.7 and 1.9.1 (not sure about 1.9) you should require files by using the construct I showed above.

You can len(list(generator)) but you could probably make something more efficient if you really intend to discard the results.

Delete /var/lib/mongodb/mongod.lock, then issue sudo service mongodb start, then mongo.

The query you want to show as an example is:

SELECT * FROM temp WHERE mydate > '2009-06-29 16:00:44';

04:00:00 is 4AM, so all the results you're displaying come after that, which is correct.

If you want to show everything after 4PM, you need to use the correct (24hr) notation in your query.

To make things a bit clearer, try this:

SELECT mydate, DATE_FORMAT(mydate, '%r') FROM temp;

That will show you the date, and its 12hr time.

In Java 8:

LinkedHashMap<Integer, String> sortedMap = 
    map.entrySet().stream().
    sorted(Entry.comparingByValue()).
    collect(Collectors.toMap(Entry::getKey, Entry::getValue,
                             (e1, e2) -> e1, LinkedHashMap::new));

The problem is that you have a circular import: in app.py

from mod_login import mod_login

from app import app

This is not permitted in Python. See Circular import dependency in Python for more info. In short, the solution are

• either gather everything in one big file
• delay one of the import using local import

This solution fixed my problem while replacing br tag to '\n' .

alert(content.replace(/<br\/\>/g,'\n'));

OpenSSH has been added to Windows as of autumn 2018, and is included in Windows 10 and Windows Server 2019.

So you can use it in command prompt or power shell like bellow.

For those looking for the shortex mutex example:

#include <mutex>

int main() {
    std::mutex m;

    m.lock();
    // do thread-safe stuff
    m.unlock();
}

HTML doesn't recognize the & but it will recognize & because it is equal to & in HTML

I looked over this post someone had made: http://www.webmasterworld.com/forum21/8851.htm

Had been messing around with IISExpress and Project to try and get it listening on a different URL than localhost, when reverting back I had this error and after following all the answers here, none of them worked.

Eventually noticed that in the projects Porperties -> Web I had 'Start URL' checked under Start Action, but the input box was empty. Changing this to 'Current Page' fixed my issue.

There is also an alternate solution for those who aren't afraid of using hex editors (e.g. XVI32) [thanks to Trevor for this]: in the unpacked ¹ installer executable (jdk-8uXX-windows-i586.exe in case of JDK) simply replace all occurrences of RegDeleteKeyExA (the name of API found in "new" ADVAPI32.DLL) with RegDeleteKeyA (legacy API name), followed by two hex '00's (to preserve padding/segmentation boundaries). The installer will complain about unsupported Windows version, but will work nevertheless.

For reference, the raw hex strings will be:

52 65 67 44 65 6C 65 74 65 4B 65 79 45 78 41

replaced with

52 65 67 44 65 6C 65 74 65 4B 65 79 41 00 00

Note: this procedure applies to both offline (standalone) and online (downloader) package.

^{1: some newer installer versions are packed with UPX - you'd need to unpack them first, otherwise you simply won't be able to find the hex string required}

Inside the folder you want to be compressed, in terminal:

zip -r -X Archive.zip *

Where -X means: Exclude those invisible Mac resource files such as “_MACOSX” or “._Filename” and .ds store files

source

Note: Will only work for the folder and subsequent folder tree you are in and has to have the * wildcard.

You likely need to delete the entry from the migrations table too.

It's getElementsByName() and getElementsByTagName() - note the "s" in "Elements", indicating that both functions return a list of elements, i.e., a NodeList, which you will access like an array. Note that the second function ends with "TagName" not "Tag".

Even if the function only returns one element it will still be in a NodeList of length one. So:

var els = document.getElementsByName('frmMain');
// els.length will be the number of elements returned
// els[0] will be the first element returned
// els[1] the second, etc.

Assuming your form is the first (or only) form on the page you can do this:

document.getElementsByName('frmMain')[0].elements
document.getElementsByTagName('table')[0].elements

i just made a proxy graber and also can connect with same grabed proxy without any input here is :

#Import Modules

from termcolor import colored
from selenium import webdriver

import time

#Proxy Grab

options = webdriver.ChromeOptions()
options.add_argument('headless')
driver = webdriver.Chrome(chrome_options=options)
driver.get("https://www.sslproxies.org/")
tbody = driver.find_element_by_tag_name("tbody")
cell = tbody.find_elements_by_tag_name("tr")
for column in cell:

        column = column.text.split(" ")
        print(colored(column[0]+":"+column[1],'yellow'))
driver.quit()
print("")

os.system('clear')
os.system('cls')

#Proxy Connection

print(colored('Getting Proxies from graber...','green'))
time.sleep(2)
os.system('clear')
os.system('cls')
proxy = {"http": "http://"+ column[0]+":"+column[1]}

As some people have mentioned, Javascript is the way to go. Bear in mind that the "validation" here is only by file extension, it won't validate that the file is a real excel spreadsheet!

You can't install and run in one go - but you can certainly use adb to start your already installed application. Use adb shell am start to fire an intent - you will need to use the correct intent for your application though. A couple of examples:

adb shell am start -a android.intent.action.MAIN -n com.android.settings/.Settings 

will launch Settings, and

adb shell am start -a android.intent.action.MAIN -n com.android.browser/.BrowserActivity 

will launch the Browser. If you want to point the Browser at a particular page, do this

adb shell am start -a android.intent.action.VIEW -n com.android.browser/.BrowserActivity http://www.google.co.uk

If you don't know the name of the activities in the APK, then do this

aapt d xmltree <path to apk> AndroidManifest.xml

the output content will includes a section like this:

   E: activity (line=32)
    A: android:theme(0x01010000)=@0x7f080000
    A: android:label(0x01010001)=@0x7f070000
    A: android:name(0x01010003)="com.anonymous.MainWindow"
    A: android:launchMode(0x0101001d)=(type 0x10)0x3
    A: android:screenOrientation(0x0101001e)=(type 0x10)0x1
    A: android:configChanges(0x0101001f)=(type 0x11)0x80
    E: intent-filter (line=33)
      E: action (line=34)
        A: android:name(0x01010003)="android.intent.action.MAIN"
        XE: (line=34)

That tells you the name of the main activity (MainWindow), and you can now run

adb shell am start -a android.intent.action.MAIN -n com.anonymous/.MainWindow

Here is my solution:

/^(2[0-9]{3})-(0[1-9]|1[012])-(0[1-9]|[12][0-9]|3[01]) (0[0-9]|1[0-9]|2[0123])\:([012345][0-9])\:([012345][0-9])$/u

pandas >= 1.1: DataFrame.compare

With pandas 1.1, you could essentially replicate Ted Petrou's output with a single function call. Example taken from the docs:

pd.__version__
# '1.1.0'

df1.compare(df2)

  score       isEnrolled       Comment             
   self other       self other    self        other
1  1.11  1.21        NaN   NaN     NaN          NaN
2   NaN   NaN        1.0   0.0     NaN  On vacation

Here, "self" refers to the LHS dataFrame, while "other" is the RHS DataFrame. By default, equal values are replaced with NaNs so you can focus on just the diffs. If you want to show values that are equal as well, use

df1.compare(df2, keep_equal=True, keep_shape=True) 

  score       isEnrolled           Comment             
   self other       self  other       self        other
1  1.11  1.21      False  False  Graduated    Graduated
2  4.12  4.12       True  False        NaN  On vacation

You can also change the axis of comparison using align_axis:

df1.compare(df2, align_axis='index')

         score  isEnrolled      Comment
1 self    1.11         NaN          NaN
  other   1.21         NaN          NaN
2 self     NaN         1.0          NaN
  other    NaN         0.0  On vacation

This compares values row-wise, instead of column-wise.

Collections.sort(testList);
Collections.reverse(testList);

That will do what you want. Remember to import Collections though!

Here is the documentation for Collections.

Here is a working solution.

class BST:
    def __init__(self,data):
        self.root = data
        self.left = None
        self.right = None

    def insert(self,data):

            self.root = BST(data)
        elif data > self.root:

You might want to look at the RouteLink() method.That one lets you specify everything (except the link text and route name) via a dictionary.

Due to security violations, organizations may have their own repositories.

set your local repo as below.

npm config set registry https://yourorg-artifactory.com/

I hope this will solve the issue.

I would unpack your gem in the application vendor folder

gem unpack your.gem --target /path_to_app/vendor/gems/

Then add the path on the Gemfile to link unpacked gem.

gem 'your', '2.0.1', :path => 'vendor/gems/your'

Use (V3 version):

(Get-Content c:\temp\test.txt).replace('[MYID]', 'MyValue') | Set-Content c:\temp\test.txt

Or for V2:

(Get-Content c:\temp\test.txt) -replace '\[MYID\]', 'MyValue' | Set-Content c:\temp\test.txt

This Worked for me

Actually error is a array which contain error message and other values for elements we pass, you can console.log(error); and see. Inside if condition "error.appendTo($(element).parents('div').find($('.errorEmail')));" Is nothing but finding html element in code and passing the error message.

    $("form[name='contactUs']").validate({
rules: {
    message: 'required',
    name: "required",
    phone_number: {
        required: true,
        minlength: 10,
        maxlength: 10,
        number: false
    },
    email: {
        required: true,
        email: true
    }
},
messages: {
    name: "Please enter your name",
    email: "Please enter a valid email address",
    message: "Please enter your message",
    phone_number: "Please enter a valid mobile number"
},
errorPlacement: function(error, element) {
        $("#errorText").empty();

        if(error[0].htmlFor == 'name')
        {
            error.appendTo($(element).parents('div').find($('.errorName')));
        }
        if(error[0].htmlFor == 'email')
        {
            error.appendTo($(element).parents('div').find($('.errorEmail')));
        }
        if(error[0].htmlFor == 'phone_number')
        {
            error.appendTo($(element).parents('div').find($('.errorMobile')));
        }
        if(error[0].htmlFor == 'message')
        {
            error.appendTo($(element).parents('div').find($('.errorMessage')));
        }
      }
    });

For boolean logic, use & and |.

np.random.seed(0)
df = pd.DataFrame(np.random.randn(5,3), columns=list('ABC'))

>>> df
          A         B         C
0  1.764052  0.400157  0.978738
1  2.240893  1.867558 -0.977278
2  0.950088 -0.151357 -0.103219
3  0.410599  0.144044  1.454274
4  0.761038  0.121675  0.443863

>>> df.loc[(df.C > 0.25) | (df.C < -0.25)]
          A         B         C
0  1.764052  0.400157  0.978738
1  2.240893  1.867558 -0.977278
3  0.410599  0.144044  1.454274
4  0.761038  0.121675  0.443863

To see what is happening, you get a column of booleans for each comparison, e.g.

df.C > 0.25
0     True
1    False
2    False
3     True
4     True
Name: C, dtype: bool

When you have multiple criteria, you will get multiple columns returned. This is why the join logic is ambiguous. Using and or or treats each column separately, so you first need to reduce that column to a single boolean value. For example, to see if any value or all values in each of the columns is True.

# Any value in either column is True?
(df.C > 0.25).any() or (df.C < -0.25).any()
True

# All values in either column is True?
(df.C > 0.25).all() or (df.C < -0.25).all()
False

One convoluted way to achieve the same thing is to zip all of these columns together, and perform the appropriate logic.

>>> df[[any([a, b]) for a, b in zip(df.C > 0.25, df.C < -0.25)]]
          A         B         C
0  1.764052  0.400157  0.978738
1  2.240893  1.867558 -0.977278
3  0.410599  0.144044  1.454274
4  0.761038  0.121675  0.443863

setup.py is a python file, the presence of which is an indication that the module/package you are about to install has likely been packaged and distributed with Distutils, which is the standard for distributing Python Modules.

This allows you to easily install Python packages. Often it's enough to write:

$ pip install . 

pip will use setup.py to install your module. Avoid calling setup.py directly.

https://docs.python.org/3/installing/index.html#installing-index

thank you @thierry-templier!

In my understanding, Get-Content eliminates ALL newlines/carriage returns when it rolls your text file through the pipeline. To do multiline regexes, you have to re-combine your string array into one giant string. I do something like:

$text = [string]::Join("`n", (Get-Content test.txt))
[regex]::Replace($text, "t`n", "ting`na ", "Singleline")

Clarification: small files only folks! Please don't try this on your 40 GB log file :)

Here is the short answer:

$ ls -ld directory

Here's what it does:

-d, --directory
    list directory entries instead of contents, and do not dereference symbolic links

You might be interested in manpages. That's where all people in here get their nice answers from.

refer to online man pages

I did it this way:

<update id="updateSettings" parameterType="PushSettings">
    <foreach collection="settings" item="setting">
        UPDATE push_setting SET status = #{setting.status}
        WHERE type = #{setting.type} AND user_id = #{userId};
    </foreach>
</update>

where PushSettings is

public class PushSettings {

    private List<PushSetting> settings;
    private String userId;
}

it works fine

Steps to manually configure DNS:

1. You can access Network and Sharing center by right clicking on the Network icon on the taskbar.

2. Now choose adapter settings from the side menu.

3. This will give you a list of the available network adapters in the system . From them right click on the adapter you are using to connect to the internet now and choose properties option.

4. In the networking tab choose ‘Internet Protocol Version 4 (TCP/IPv4)’.

5. Now you can see the properties dialogue box showing the properties of IPV4. Here you need to change some properties.

   Select ‘use the following DNS address’ option. Now fill the following fields as given here.

   Preferred DNS server: 208.67.222.222

   Alternate DNS server : 208.67.220.220

   This is an available Open DNS address. You may also use google DNS server addresses.

   After filling these fields. Check the ‘validate settings upon exit’ option. Now click OK.

You have to add this DNS server address in the router configuration also (by referring the router manual for more information).

Refer : for above method & alternative

If none of this works, then open command prompt(Run as Administrator) and run these:

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
NETSH winsock reset catalog
NETSH int ipv4 reset reset.log
NETSH int ipv6 reset reset.log
Exit

Hopefully that fixes it, if its still not fixed there is a chance that its a NIC related issue(driver update or h/w).

Also FYI, this has a thread on Microsoft community : Windows 10 - DNS Issue

NotificationManager.cancel(id) is the correct answer. Yet you can remove in Android Oreo and later notifications by deleting the whole notification channel. This should delete all messages in the deleted channel.

Here is the example from the Android documentation:

NotificationManager mNotificationManager =
        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// The id of the channel.
String id = "my_channel_01";
mNotificationManager.deleteNotificationChannel(id);

Ctrl+C is what you need. If it didn't work, hit it harder. :-) Of course, you can also just close the shell window.

Edit: You didn't mention the circumstances. As a last resort, you could write a batch file that contains taskkill /im python.exe, and put it on your desktop, Start menu, etc. and run it when you need to kill a runaway script. Of course, it will kill all Python processes, so be careful.

yeah it works for me as well.

Note : we need to use window.parent.document

    $("button", window.parent.document).click(function()
    {
        alert("Functionality defined by def");
    });

The message means that both the packages have functions with the same names. In this particular case, the testthat and assertive packages contain five functions with the same name.

When two functions have the same name, which one gets called?

R will look through the search path to find functions, and will use the first one that it finds.

search()
 ##  [1] ".GlobalEnv"        "package:assertive" "package:testthat" 
 ##  [4] "tools:rstudio"     "package:stats"     "package:graphics" 
 ##  [7] "package:grDevices" "package:utils"     "package:datasets" 
 ## [10] "package:methods"   "Autoloads"         "package:base"

In this case, since assertive was loaded after testthat, it appears earlier in the search path, so the functions in that package will be used.

is_true
## function (x, .xname = get_name_in_parent(x)) 
## {
##     x <- coerce_to(x, "logical", .xname)
##     call_and_name(function(x) {
##         ok <- x & !is.na(x)
##         set_cause(ok, ifelse(is.na(x), "missing", "false"))
##     }, x)
## }
<bytecode: 0x0000000004fc9f10>
<environment: namespace:assertive.base>

The functions in testthat are not accessible in the usual way; that is, they have been masked.

What if I want to use one of the masked functions?

You can explicitly provide a package name when you call a function, using the double colon operator, ::. For example:

testthat::is_true
## function () 
## {
##     function(x) expect_true(x)
## }
## <environment: namespace:testthat>

How do I suppress the message?

If you know about the function name clash, and don't want to see it again, you can suppress the message by passing warn.conflicts = FALSE to library.

library(testthat)
library(assertive, warn.conflicts = FALSE)
# No output this time

Alternatively, suppress the message with suppressPackageStartupMessages:

library(testthat)
suppressPackageStartupMessages(library(assertive))
# Also no output

Impact of R's Startup Procedures on Function Masking

If you have altered some of R's startup configuration options (see ?Startup) you may experience different function masking behavior than you might expect. The precise order that things happen as laid out in ?Startup should solve most mysteries.

For example, the documentation there says:

Note that when the site and user profile files are sourced only the base package is loaded, so objects in other packages need to be referred to by e.g. utils::dump.frames or after explicitly loading the package concerned.

Which implies that when 3rd party packages are loaded via files like .Rprofile you may see functions from those packages masked by those in default packages like stats, rather than the reverse, if you loaded the 3rd party package after R's startup procedure is complete.

How do I list all the masked functions?

First, get a character vector of all the environments on the search path. For convenience, we'll name each element of this vector with its own value.

library(dplyr)
envs <- search() %>% setNames(., .)

For each environment, get the exported functions (and other variables).

fns <- lapply(envs, ls)

Turn this into a data frame, for easy use with dplyr.

fns_by_env <- data_frame(
  env = rep.int(names(fns), lengths(fns)),
  fn  = unlist(fns)
)

Find cases where the object appears more than once.

fns_by_env %>% 
  group_by(fn) %>% 
  tally() %>% 
  filter(n > 1) %>% 
  inner_join(fns_by_env)

To test this, try loading some packages with known conflicts (e.g., Hmisc, AnnotationDbi).

How do I prevent name conflict bugs?

The conflicted package throws an error with a helpful error message, whenever you try to use a variable with an ambiguous name.

library(conflicted)
library(Hmisc)
units
## Error: units found in 2 packages. You must indicate which one you want with ::
##  * Hmisc::units
##  * base::units

Is there any 64 bit Visual Studio at all?

Yes literally there is one called "Visual Studio" and is 64bit, but well,, on Mac not on Windows

Why not?

Decision making is electro-chemical reaction made in our brain and that have an activation point (Nerdest answer I can come up with, but follow). Same situation happened in history: Windows 64!...

So in order to answer this fully I want you to remember old days. Imagine reasons for "why not we see 64bit Windows" are there at the time. I think at the time for Windows64 they had exact same reasons others have enlisted here about "reasons why not 64bit VS on windows" were on "reasons why not 64bit Windows" too. Then why they did start development for Windows 64bit? Simple! If they didn't succeed in making 64bit Windows I bet M$ would have been a history nowadays. If same reasons forcing M$ making 64bit Windows starts to appear on need for 64Bit VS then I bet we will see 64bit VS, even though very same reasons everyone else here enlisted will stay same! In time the limitations of 32bit may hit VS as well, so most likely something like below start to happen:

• Visual Studio will drop 32bit support and become 64bit,
• Visual Studio Code will take it's place instead,
• Visual Studio will have similar functionality like WOW64 for old extensions which is I believe unlikely to happen.

I put my bets on Visual Studio Code taking the place in time; I guess bifurcation point for it will be some CPU manufacturer X starts to compete x86_64 architecture taking its place on mainstream market for laptop and/or workstation,

If you are running a Windows container on a Service Fabric cluster, the host's IP address is available via the environment variable Fabric_NodeIPOrFQDN. Service Fabric environment variables

Try this example

CREATE PROCEDURE MyProc
BEGIN
    --Stored Procedure variables
    Declare @maxOr int; 
    Declare @maxCa int; 

    --Getting query result in the variable (first variant of syntax)
    SET @maxOr = (SELECT MAX(orId) FROM [order]); 

    --Another variant of seting variable from query
    SELECT @maxCa=MAX(caId) FROM [cart]; 

    --Updating record through the variable
    INSERT INTO [order_cart] (orId,caId)
    VALUES(@maxOr, @maxCa); 

    --return values to the program as dataset
    SELECT
       @maxOr AS maxOr,
       @maxCa AS maxCa

    -- return one int value as "return value"
    RETURN @maxOr
END
GO

SQL-command to call the stored procedure

EXEC MyProc

As a different font is likely to be already defined by the browser for form elements, here are 2 ways to use this font everywhere:

body, input, textarea {
    font-family: Algerian;
}

body {
    font-family: Algerian !important;
}

There'll still have a monospace font on elements like pre/code, kbd, etc but, in case you use these elements, you'd better use a monospace font there.

Important note: if very few people has this font installed on their OS, then the second font in the list will be used. Here you defined no second font so the default serif font will be used, and it'll be Times, Times New Roman except maybe on Linux.
Two options there: use @font-face if your font is free of use as a downloadable font or add fallback(s): a second, a third, etc and finally a default family (sans-serif, cursive (*), monospace or serif). The first of the list that exists on the OS of the user will be used.

(*) default cursive on Windows is Comic Sans. Except if you want to troll Windows users, don't do that :) This font is terrible except for your children birthdays where it's welcome.

Update - I verified the below works. Maybe the creation of your JArray isn't quite right.

        foreach (var item in trendsArray.Children())
        {
            var itemProperties = item.Children<JProperty>();
            //you could do a foreach or a linq here depending on what you need to do exactly with the value
            var myElement = itemProperties.FirstOrDefault(x => x.Name == "url");
            var myElementValue = myElement.Value; ////This is a JValue type
        }
    }

So call Children on your JArray to get each JObject in JArray. Call Children on each JObject to access the objects properties.

foreach(var item in yourJArray.Children())
{
    var itemProperties = item.Children<JProperty>();
    //you could do a foreach or a linq here depending on what you need to do exactly with the value
    var myElement = itemProperties.FirstOrDefault(x => x.Name == "url");
    var myElementValue = myElement.Value; ////This is a JValue type
}

If css3 is an option, this can be done using the css calc() function.

Case 1: Justifying boxes on a single line ( FIDDLE )

Markup is simple - a bunch of divs with some container element.

CSS looks like this:

div
{
    height: 100px;
    float: left;
    background:pink;
    width: 50px;
    margin-right: calc((100% - 300px) / 5 - 1px); 
}
div:last-child
{
    margin-right:0;
}

where -1px to fix an IE9+ calc/rounding bug - see here

Case 2: Justifying boxes on multiple lines ( FIDDLE )

Here, in addition to the calc() function, media queries are necessary.

The basic idea is to set up a media query for each #columns states, where I then use calc() to work out the margin-right on each of the elements (except the ones in the last column).

This sounds like a lot of work, but if you're using LESS or SASS this can be done quite easily

(It can still be done with regular css, but then you'll have to do all the calculations manually, and then if you change your box width - you have to work out everything again)

Below is an example using LESS: (You can copy/paste this code here to play with it, [it's also the code I used to generate the above mentioned fiddle])

@min-margin: 15px;
@div-width: 150px;

@3divs: (@div-width * 3);
@4divs: (@div-width * 4);
@5divs: (@div-width * 5);
@6divs: (@div-width * 6);
@7divs: (@div-width * 7);

@3divs-width: (@3divs + @min-margin * 2);
@4divs-width: (@4divs + @min-margin * 3);
@5divs-width: (@5divs + @min-margin * 4);
@6divs-width: (@6divs + @min-margin * 5);
@7divs-width: (@7divs + @min-margin * 6);


*{margin:0;padding:0;}

.container
{
    overflow: auto;
    display: block;
    min-width: @3divs-width;
}
.container > div
{
    margin-bottom: 20px;
    width: @div-width;
    height: 100px;
    background: blue;
    float:left;
    color: #fff;
    text-align: center;
}

@media (max-width: @3divs-width) {
    .container > div {  
        margin-right: @min-margin;
    }
    .container > div:nth-child(3n) {  
        margin-right: 0;
    }
}

@media (min-width: @3divs-width) and (max-width: @4divs-width) {
    .container > div {  
        margin-right: ~"calc((100% - @{3divs})/2 - 1px)";
    }
    .container > div:nth-child(3n) {  
        margin-right: 0;
    }
}

@media (min-width: @4divs-width) and (max-width: @5divs-width) {
    .container > div {  
        margin-right: ~"calc((100% - @{4divs})/3 - 1px)";
    }
    .container > div:nth-child(4n) {  
        margin-right: 0;
    }
}

@media (min-width: @5divs-width) and (max-width: @6divs-width) {
    .container > div {  
        margin-right: ~"calc((100% - @{5divs})/4 - 1px)";
    }
    .container > div:nth-child(5n) {  
        margin-right: 0;
    }
}

@media (min-width: @6divs-width){
    .container > div {  
        margin-right: ~"calc((100% - @{6divs})/5 - 1px)";
    }
    .container > div:nth-child(6n) {  
        margin-right: 0;
    }
}

So basically you first need to decide a box-width and a minimum margin that you want between the boxes.

With that, you can work out how much space you need for each state.

Then, use calc() to calcuate the right margin, and nth-child to remove the right margin from the boxes in the final column.

The advantage of this answer over the accepted answer which uses text-align:justify is that when you have more than one row of boxes - the boxes on the final row don't get 'justified' eg: If there are 2 boxes remaining on the final row - I don't want the first box to be on the left and the next one to be on the right - but rather that the boxes follow each other in order.

Regarding browser support: This will work on IE9+,Firefox,Chrome,Safari6.0+ - (see here for more details) However i noticed that on IE9+ there's a bit of a glitch between media query states. [if someone knows how to fix this i'd really like to know :) ] <-- FIXED HERE

You can also retrieve it from the environment variables, but that is probably not secure, so I would go with Andrew's answer.

printenv USER

If you need to retrieve it from an app, like Node, it's easier to get it from the environment variables, such as

process.env.USER.

I'll try to answer the why question: The Java array is very simple and rudimentary compared to classes like ArrayList, that are more dynamic. Java wants to know at declaration time how much memory should be allocated for the array. An ArrayList is much more dynamic and the size of it can vary over time.

If you initialize your array with the length of two, and later on it turns out you need a length of three, you have to throw away what you've got, and create a whole new array. Therefore the 'new' keyword.

In your first two examples, you tell at declaration time how much memory to allocate. In your third example, the array name becomes a pointer to nothing at all, and therefore, when it's initialized, you have to explicitly create a new array to allocate the right amount of memory.

I would say that (and if someone knows better, please correct me) the first example

AClass[] array = {object1, object2}

actually means

AClass[] array = new AClass[]{object1, object2};

but what the Java designers did, was to make quicker way to write it if you create the array at declaration time.

The suggested workarounds are good. If the time or memory usage is critical at runtime, use arrays. If it's not critical, and you want code that is easier to understand and to work with, use ArrayList.

public static List<HtmlNode> GetTagsWithClass(string html,List<string> @class)
    {
        // LoadHtml(html);           
        var result = htmlDocument.DocumentNode.Descendants()
            .Where(x =>x.Attributes.Contains("class") && @class.Contains(x.Attributes["class"].Value)).ToList();          
        return result;
    }      

_var has no meaning and only serves the purpose of making it easier to distinguish that the variable is a private member variable.

In C++, using the _var convention is bad form, because there are rules governing the use of the underscore in front of an identifier. _var is reserved as a global identifier, while _Var (underscore + capital letter) is reserved anytime. This is why in C++, you'll see people using the var_ convention instead.

Since API 14 you can use the function onTrimMemory() and check for the flag TRIM_MEMORY_UI_HIDDEN. This will tell you that your Application is going to the background.

So in your custom Application class you can write something like:

override fun onTrimMemory(level: Int) {
    if (level == TRIM_MEMORY_UI_HIDDEN) {
        // Application going to background, do something
    }
}

For an in-depth study of this, I invite you to read this article: http://www.developerphil.com/no-you-can-not-override-the-home-button-but-you-dont-have-to/

Here's the GNU version of printf... you can see it passing in stdout to vfprintf:

__printf (const char *format, ...)
{
   va_list arg;
   int done;

   va_start (arg, format);
   done = vfprintf (stdout, format, arg);
   va_end (arg);

   return done;
}

See here.

Here's a link to vfprintf... all the formatting 'magic' happens here.

The only thing that's truly 'different' about these functions is that they use varargs to get at arguments in a variable length argument list. Other than that, they're just traditional C. (This is in contrast to Pascal's printf equivalent, which is implemented with specific support in the compiler... at least it was back in the day.)

You must write that function body outside the ready();

because ready is used to call a function or to bind a function with binding id like this.

$(document).ready(function() {
    $("Some id/class name").click(function(){
        alert("i'm in");
    });
});

but you can't do this if you are calling "showAmount" function onchange/onclick event

$(document).ready(function() {
    function showAmount(value){
        alert(value);
    }

});

You have to write "showAmount" outside the ready();

function showAmount(value){
    alert(value);//will be called on event it is bind with
}
$(document).ready(function() {
    alert("will display on page load")
});

The simplest way with quotation marks:

B=Bar
b=bar
var="$B""$b""a"
echo "Hello ""$var"

Cloudfront will cache a file/object until the cache expiry. By default it is 24 hrs. If you have changed this to a large value, then it takes longer.

If you anytime needs to force clear the cache, use the invalidation. It is charged separately.

Another option is to change the URL (object key), so it fetches the new object always.

You can use Environment.Exit(0); and Application.Exit

Environment.Exit(0) is cleaner.

From the documentation,

Positioning your Toast

A standard toast notification appears near the bottom of the screen, centered horizontally. You can change this position with the setGravity(int, int, int) method. This accepts three parameters: a Gravity constant, an x-position offset, and a y-position offset.

For example, if you decide that the toast should appear in the top-left corner, you can set the gravity like this:

toast.setGravity(Gravity.TOP|Gravity.LEFT, 0, 0);

If you want to nudge the position to the right, increase the value of the second parameter. To nudge it down, increase the value of the last parameter.

I use Log.d method also please import import android.util.Log;

Log.d("TAG", "Message");

But please keep in mind that, when you want to see the debug messages then don't use Run As rather use "Debug As" then select Android Application. Otherwise you'll not see the debug messages.

Two ways.

i. You can put it in ApplicationController and add the filters in the controller

    class ApplicationController < ActionController::Base       def filter_method       end     end      class FirstController < ApplicationController       before_filter :filter_method     end      class SecondController < ApplicationController       before_filter :filter_method     end 

But the problem here is that this method will be added to all the controllers since all of them extend from application controller

ii. Create a parent controller and define it there

 class ParentController < ApplicationController   def filter_method   end  end  class FirstController < ParentController   before_filter :filter_method end  class SecondController < ParentController   before_filter :filter_method end 

I have named it as parent controller but you can come up with a name that fits your situation properly.

You can also define the filter method in a module and include it in the controllers where you need the filter

A simpler version of user3608934's idea "This is an old trick, create a string with 16 0's then append the trimmed binary string you got ":

private String toBinaryString32(int i) {
    String binaryWithOutLeading0 = Integer.toBinaryString(i);
    return "00000000000000000000000000000000"
            .substring(binaryWithOutLeading0.length())
            + binaryWithOutLeading0;
}

Sweet and simple definitions, but fitting the need: Statically typed languages binds the type to a variable for its entire scope (Seg: SCALA) Dynamically typed languages bind the type to the actual value referenced by a variable.

A very simple test to set and get 100k unique keys and values against redis-2.2.2 and memcached. Both are running on linux VM(CentOS) and my client code(pasted below) runs on windows desktop.

Redis

• Time taken to store 100000 values is = 18954ms

• Time taken to load 100000 values is = 18328ms

Memcached

• Time taken to store 100000 values is = 797ms

• Time taken to retrieve 100000 values is = 38984ms

Jedis jed = new Jedis("localhost", 6379);
int count = 100000;
long startTime = System.currentTimeMillis();
for (int i=0; i<count; i++) {
  jed.set("u112-"+i, "v51"+i);
}
long endTime = System.currentTimeMillis();
System.out.println("Time taken to store "+ count + " values is ="+(endTime-startTime)+"ms");

startTime = System.currentTimeMillis();
for (int i=0; i<count; i++) {
  client.get("u112-"+i);
}
endTime = System.currentTimeMillis();
System.out.println("Time taken to retrieve "+ count + " values is ="+(endTime-startTime)+"ms");

To centre align a div you should apply the style

div 
{
    margin: 0 auto;
}

I may also add, that nowadays it is possible to decompile Android application online, no software needed!

Here are 2 options for you:

• http://www.decompileandroid.com/
• http://www.javadecompilers.com/apk

You can download from below link. ftp://ftp.comtrol.com/dev_mstr/sdk/other/1800136.tar.gz After downloading just extract the image and install.

I create a student table with three column id, student,age. show you this example

declare @id int 
select @id = 1
while @id >=1 and @id <= 1000
begin
    insert into student values(@id, 'jack' + convert(varchar(5), @id), 12)
    select @id = @id + 1
end

this is the result about the example

You can't access the method fxn since it's not static. Static methods can only access other static methods directly. If you want to use fxn in your main method you need to:

...
Two two = new Two();
x = two.fxn(x)
...

That is, make a Two-Object and call the method on that object.

...or make the fxn method static.

Find the Run button present on the top of the Eclipse, then select Run Configuration -> Arguments, in VM arguments section just mention the heap size you want to extend as below:

-Xmx1024m

Considering it hasn't been released yet, I'm assuming this is a question for ahead-of-time or you have a developer's build. As Benjamin mentioned, MAMP is the easiest way. However, if you want a native install, the process should be like 10.5. PHP comes installed on OS X by default (not always activated for some), just download the 32-bit version of MySQL, start Apache, and you should be good to go. You may have to tweak Apache for PHP or MySQL, depending on what builds are present. I didn't have to tweak anything to have it working.

If, running an Oracle HotSpot JDK 1.7.x, on a Linux platform where your locale suggests UTF-8 (e.g. LANG=en_US.utf8), if you don't set it on the command-line with -Dfile.encoding, the JDK will default file.encoding and the default Charset like this:

System.out.println(String.format("file.encoding: %s", System.getProperty("file.encoding")));
System.out.println(String.format("defaultCharset: %s", Charset.defaultCharset().name()));

... yields:

file.encoding: UTF-8
defaultCharset: UTF-8

... suggesting the default is UTF-8 on such a platform.

Additionally, if java.nio.charset.Charset.defaultCharset() finds file.encoding not-set, it looks for java.nio.charset.Charset.forName("UTF-8"), suggesting it prefers that string, although it is well-aliased, so "UTF8" will also work fine.

If you run the same program on the same platform with java -Dfile.encoding=UTF8, without the hypen, it yields:

file.encoding: UTF8
defaultCharset: UTF-8

... noting that the default charset has been canonicalized from UTF8 to UTF-8.

To define "soft real-time," it is easiest to compare it with "hard real-time." Below we will see that the term "firm real-time" constitutes a misunderstanding about "soft real-time."

Speaking casually, most people implicitly have an informal mental model that considers information or an event as being "real-time"

• if, or to the extent that, it is manifest to them with a delay (latency) that can be related to its perceived currency

• i.e., in a time frame that the information or event has acceptably satisfactory value to them.

There are numerous different ad hoc definitions of "hard real-time," but in that mental model, hard real-time is represented by the "if" term. Specifically, assuming that real-time actions (such as tasks) have completion deadlines, acceptably satisfactory value of the event that all tasks complete is limited to the special case that all tasks meet their deadlines.

Hard real-time systems make the very strong assumptions that everything about the application and system and environment is static and known a' priori—e.g., which tasks, that they are periodic, their arrival times, their periods, their deadlines, that they won’t have resource conflicts, and overall the time evolution of the system. In an aircraft flight control system or automotive braking system and many other cases those assumptions can usually be satisfied so that all the deadlines will be met.

This mental model is deliberately and very usefully general enough to encompass both hard and soft real-time--soft is accommodated by the "to the extent that" phrase. For example, suppose that the task completions event has suboptimal but acceptable value if

• no more than 10% of the tasks miss their deadlines
• or no task is more than 20% tardy
• or the average tardiness of all tasks is no more than 15%
• or the maximum tardiness among all tasks is less than 10%

These are all common examples of soft real-time cases in a great many applications.

Consider the single-task application of picking your child up after school. That probably does not have an actual deadline, instead there is some value to you and your child based on when that event takes place. Too early wastes resources (such as your time) and too late has some negative value because your child might be left alone and potentially in harm's way (or at least inconvenienced).

Unlike the static hard real-time special case, soft real-time makes only the minimum necessary application-specific assumptions about the tasks and system, and uncertainties are expected. To pick up your child, you have to drive to the school, and the time to do that is dynamic depending on weather, traffic conditions, etc. You might be tempted to over-provision your system (i.e., allow what you hope is the worst case driving time) but again this is wasting resources (your time, and occupying the family vehicle, possibly denying use by other family members).

That example may not seem to be costly in terms of wasted resources, but consider other examples. All military combat systems are soft real-time. For example, consider performing an aircraft attack on a hostile ground vehicle using a missile guided with updates to it as the target maneuvers. The maximum satisfaction for completing the course update tasks is achieved by a direct destructive strike on the target. But an attempt to over-provision resources to make certain of this outcome is usually far too expensive and may even be impossible. In this case, you may be less but sufficiently satisfied if the missile strikes close enough to the target to disable it.

Obviously combat scenarios have a great many possible dynamic uncertainties that must be accommodated by the resource management. Soft real-time systems are also very common in many civilian systems, such as industrial automation, although obviously military ones are the most dangerous and urgent ones to achieve acceptably satisfactory value in.

The keystone of real-time systems is "predictability." The hard real-time case is interested in only one special case of predictability--i.e., that the tasks will all meet their deadlines and the maximum possible value will be achieved by that event. That special case is named "deterministic."

There is a spectrum of predictability. Deterministic (determinism) is one end-point (maximum predictability) on the predictability spectrum; the other end-point is minimum predictability (maximum non-determinism). The spectrum's metric and end-points have to be interpreted in terms of a chosen predictability model; everything between those two end-points is degrees of unpredictability (= degrees of non-determinism).

Most real-time systems (namely, soft ones) have non-deterministic predictability, for example, of the tasks' completions times and hence the values gained from those events.

In general (in theory), predictability, and hence acceptably satisfactory value, can be made as close to the deterministic end-point as necessary--but at a price which may be physically impossible or excessively expensive (as in combat or perhaps even in picking up your child from school).

Soft real-time requires an application-specific choice of a probability model (not the common frequentist model) and hence predictability model for reasoning about event latencies and resulting values.

Referring back to the above list of events that provide acceptable value, now we can add non-deterministic cases, such as

• the probability that no task will miss its deadline by more than 5% is greater than 0.87. (Note the number of scheduling criteria expressed in there.)

In a missile defense application, given the fact that in combat the offense always has the advantage over the defense, which of these two real-time computing scenarios would you prefer:

• because the perfect destruction of all the hostile missiles is very unlikely or impossible, assign your defensive resources to maximize the probability that as many of the most threatening (e.g., based on their targets) hostile missiles will be successfully intercepted (close interception counts because it can move the hostile missile off-course);

• complain that this is not a real-time computing problem because it is dynamic instead of static, and traditional real-time concepts and techniques do not apply, and it sounds more difficult than static hard real-time, so you are not interested in it.

Despite the various misunderstandings about soft real-time in the real-time computing community, soft real-time is very general and powerful, albeit potentially complex compared with hard real-time. Soft real-time systems as summarized here have a lengthy successful history of use outside the real-time computing community.

To directly answer the OP question:

A hard real-time system can provide deterministic guarantees—most commonly that all tasks will meet their deadlines, interrupt or system call response time will always be less than x, etc.—IF AND ONLY IF very strong assumptions are made and are correct that everything that matters is static and known a' priori (in general, such guarantees for hard real-time systems are an open research problem except for rather simple cases)

A soft real-time system does not make deterministic guarantees, it is intended to provide the best possible analytically specified and accomplished probabilistic timeliness and predictability of timeliness that are feasible under the current dynamic circumstances, according to application-specific criteria.

Obviously hard real-time is a simple special case of soft real-time. Obviously soft real-time's analytical non-deterministic assurances can be very complex to provide, but are mandatory in the most common real-time cases (including the most dangerous safety-critical ones such as combat) since most real-time cases are dynamic not static.

"Firm real-time" is an ill-defined special case of "soft real-time." There is no need for this term if the term "soft real-time" is understood and used properly.

I have a more detailed much more precise discussion of real-time, hard real-time, soft real-time, predictability, determinism, and related topics on my web site real-time.org.

Declaring a two dimensional ArrayList:

ArrayList<ArrayList<String>> rows = new ArrayList<String>();

Or

ArrayList<ArrayList<String>> rows = new ArrayList<>();

Or

ArrayList<ArrayList<String>> rows = new ArrayList<ArrayList<String>>(); 

All the above are valid declarations for a two dimensional ArrayList!

Now, Declaring a one dimensional ArrayList:

ArrayList<String> row = new ArrayList<>();

Inserting values in the two dimensional ArrayList:

for(int i=0; i<5; i++){
    ArrayList<String> row = new ArrayList<>();
    for(int j=0; j<5; j++){
        row.add("Add values here"); 
    }
    rows.add(row); 
}

fetching the values from the two dimensional ArrayList:

for(int i=0; i<5; i++){
    for(int j=0; j<5; j++){
        System.out.print(rows.get(i).get(j)+" ");
     }
     System.out.println("");

1. If your version of Android SDK Tools is lower than 22.6, you must update

2. Under Android 4.4.2, select Android Wear ARM EABI v7a System Image and install it.

3. Under Extras, ensure that you have the latest version of the Android Support Library. If an update is available, select Android Support Library. If you're using Android Studio, also select Android Support Repository.

Below is the snapshot of what it should look like:

Then you must check the following in order to create a Wearable AVD:

1. For the Device, select Android Wear Square or Android Wear Round.

2. For the Target, select Android 4.4.2 - API Level 19 (or higher, otherwise corresponding system image will not show up.).

3. For the CPU/ABI, select Android Wear ARM (armeabi-v7a).

4. For the Skin, select AndroidWearSquare or AndroidWearRound.

5. Leave all other options set to their defaults and click OK.

Then you are good to go. For more information you can always refer to the developer site.

To check the number of times a release file/package was downloaded you can go to https://githubstats0.firebaseapp.com

It gives you a total download count and a break up of of total downloads per release tag.

The 'Answer' didn't work for me some reasons. So here is what I ended up doing:

////var group = new L.featureGroup(markerArray);//getting 'getBounds() not a function error.
////map.fitBounds(group.getBounds());
var bounds = L.latLngBounds(markerArray);
map.fitBounds(bounds);//works!

First, let me explain what a mem-initializer-list is. A mem-initializer-list is a comma-separated list of mem-initializers, where each mem-initializer is a member name followed by (, followed by an expression-list, followed by a ). The expression-list is how the member is constructed. For example, in

static const char s_str[] = "bodacydo";
class Example
{
private:
    int *ptr;
    string name;
    string *pname;
    string &rname;
    const string &crname;
    int age;

public:
    Example()
        : name(s_str, s_str + 8), rname(name), crname(name), age(-4)
    {
    }
};

the mem-initializer-list of the user-supplied, no-arguments constructor is name(s_str, s_str + 8), rname(name), crname(name), age(-4). This mem-initializer-list means that the name member is initialized by the std::string constructor that takes two input iterators, the rname member is initialized with a reference to name, the crname member is initialized with a const-reference to name, and the age member is initialized with the value -4.

Each constructor has its own mem-initializer-list, and members can only be initialized in a prescribed order (basically the order in which the members are declared in the class). Thus, the members of Example can only be initialized in the order: ptr, name, pname, rname, crname, and age.

When you do not specify a mem-initializer of a member, the C++ standard says:

If the entity is a nonstatic data member ... of class type ..., the entity is default-initialized (8.5). ... Otherwise, the entity is not initialized.

Here, because name is a nonstatic data member of class type, it is default-initialized if no initializer for name was specified in the mem-initializer-list. All other members of Example do not have class type, so they are not initialized.

When the standard says that they are not initialized, this means that they can have any value. Thus, because the above code did not initialize pname, it could be anything.

Note that you still have to follow other rules, such as the rule that references must always be initialized. It is a compiler error to not initialize references.

If your XML goes quite deep, you might want to consider using XPath, which comes with your JRE, so you can access the contents far more easily using:

String text = xp.evaluate("//add[@job='351']/tag[position()=1]/text()", 
    document.getDocumentElement());

Full example:

import static org.junit.Assert.assertEquals;
import java.io.StringReader;    
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathFactory;    
import org.junit.Before;
import org.junit.Test;
import org.w3c.dom.Document;
import org.xml.sax.InputSource;

public class XPathTest {

    private Document document;

    @Before
    public void setup() throws Exception {
        String xml = "<add job=\"351\"><tag>foobar</tag><tag>foobar2</tag></add>";
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        document = db.parse(new InputSource(new StringReader(xml)));
    }

    @Test
    public void testXPath() throws Exception {
        XPathFactory xpf = XPathFactory.newInstance();
        XPath xp = xpf.newXPath();
        String text = xp.evaluate("//add[@job='351']/tag[position()=1]/text()",
                document.getDocumentElement());
        assertEquals("foobar", text);
    }
}

Improvement on Bludream's answer:

You can definitely use FontAwesome!

Make sure to include "collapsed" along with "panel-heading" class. The "collapsed" class is not included until you click on the panel so you want to include the "collapsed" class in order to display the correct chevron (i.e., chevron-right is displayed when collapsed and chevron-down when open).

HTML

<div class="panel panel-default">
    <div class="panel-heading collapsed" data-toggle="collapse" data-target="#collapseOrderItems1">Products 1 <i class="chevron fa fa-fw" ></i></div>
    <div class="collapse" id="collapseOrderItems1">
        <p>Lorem ipsum...</p>
    </div>
</div>

CSS

.panel-heading .chevron:after {
    content: "\f078";   
}
.panel-heading.collapsed .chevron:after {
    content: "\f054";   
}   

Also, it is a good practice to create a new class instead of using an existing class.

See Codepen for example: http://codepen.io/anon/pen/PPxOJX

Create an Event object and pass it to the dispatchEvent method of the element:

var element = document.getElementById('just_an_example');
var event = new Event('change');
element.dispatchEvent(event);

This will trigger event listeners regardless of whether they were registered by calling the addEventListener method or by setting the onchange property of the element.

If you want the event to bubble, you need to pass a second argument to the Event constructor:

var event = new Event('change', { bubbles: true });

Information about browser compability:

• dispatchEvent()
• Event()

An easy way of doing this is to use JavaScript like so:

element.addEventListener('click', (e => {
    e.preventDefault();

    element.style = '<insert CSS here as you would in a style attribute>';
}));

First of all, android.graphics.Color is a class thats composed of only static methods. How and why did you create a new android.graphics.Color object? (This is completely useless and the object itself stores no data)

But anyways... I'm going to assume your using some object that actually stores data...

A integer is composed of 4 bytes (in java). Looking at the function getRGB() from the standard java Color object we can see java maps each color to one byte of the integer in the order ARGB (Alpha-Red-Green-Blue). We can replicate this behavior with a custom method as follows:

public int getIntFromColor(int Red, int Green, int Blue){
    Red = (Red << 16) & 0x00FF0000; //Shift red 16-bits and mask out other stuff
    Green = (Green << 8) & 0x0000FF00; //Shift Green 8-bits and mask out other stuff
    Blue = Blue & 0x000000FF; //Mask out anything not blue.

    return 0xFF000000 | Red | Green | Blue; //0xFF000000 for 100% Alpha. Bitwise OR everything together.
}

This assumes you can somehow retrieve the individual red, green and blue colour components and that all the values you passed in for the colours are 0-255.

If your RGB values are in form of a float percentage between 0 and 1 consider the following method:

public int getIntFromColor(float Red, float Green, float Blue){
    int R = Math.round(255 * Red);
    int G = Math.round(255 * Green);
    int B = Math.round(255 * Blue);

    R = (R << 16) & 0x00FF0000;
    G = (G << 8) & 0x0000FF00;
    B = B & 0x000000FF;

    return 0xFF000000 | R | G | B;
}

As others have stated, if you're using a standard java object, just use getRGB();

If you decide to use the android color class properly you can also do:

int RGB = android.graphics.Color.argb(255, Red, Green, Blue); //Where Red, Green, Blue are the RGB components. The number 255 is for 100% Alpha

or

int RGB = android.graphics.Color.rgb(Red, Green, Blue); //Where Red, Green, Blue are the RGB components.

as others have stated... (Second function assumes 100% alpha)

Both methods basically do the same thing as the first method created above.

Codeigniter has a function that retrieves your base path which is:

FCPATH and BASEPATH i recommand use FCPATH.

for your base url use:

<?=base_url()?>

if your php short tag is off

<?php echo base_url(); ?>

for example: if you want to link you css files which is in your base path

<script src='<?=base_url()?>js/jquery.js' type='text/javascript' />

What about something simple like:

document.getElementById('elementID').click();

Supported even by IE.

Perhaps am late or maybe you've already used it before but there is another one called ksoap and its pretty amazing.. It also includes timeouts and can parse any SOAP based webservice efficiently. I also made a few changes to suit my parsing.. Look it up

What is a when you call Ancestors('A',a)? If a['A'] is None, or if a['A'][0] is None, you'd receive that exception.

What do you mean timestamp? If you mean milliseconds since the Unix epoch:

GregorianCalendar cal = new GregorianCalendar(2007, 9 - 1, 23);
long millis = cal.getTimeInMillis();

If you want an actual java.sql.Timestamp object:

Timestamp ts = new Timestamp(millis);

Take two numbers, lets say 9 and 10, write them as binary - 1001 and 1010.

Start with a result, R, of 0.

Take one of the numbers, 1010 in this case, we'll call it A, and shift it right by one bit, if you shift out a one, add the first number, we'll call it B, to R.

Now shift B left by one bit and repeat until all bits have been shifted out of A.

It's easier to see what's going on if you see it written out, this is the example:

      0
   0000      0
  10010      1
 000000      0
1001000      1
 ------
1011010

I added $(inherited) but my project was still not compiling. For me problem was flag "Build for active Architecture only", I had to set it to YES.

The Problem is caused by mksdcard not being installed correctly.

if you are running 64 bit, do this to fix the mksdcard problem.

    sudo dpkg --add-architecture amd64
    sudo apt-get update
    sudo apt-get install libncurses5:amd64 libstdc++6:amd64 zlib1g:amd64

and 32 bit:

    sudo dpkg --add-architecture i386
    sudo apt-get update
    sudo apt-get install libncurses5:i386 libstdc++6:i386 zlib1g:i386

In SDK 6.0, the error message is different but means the same thing.

    Unable to run mksdcard

unlink is the right php function for your use case.

unlink('/path/to/file');

Without more information, I can't tell you what went wrong when you used it.

var obj = new Dictionary<string, object>;
...
Console.WriteLine(obj["MyString"]);

I think that only works because everything has a ToString(), otherwise you'd have to know the type that it was and cast the 'object' to that type.

Some of these are useful more often than others, I'm trying to be thorough.

1. It may be far more natural to access a collection, in this case what is effectively a "dictionary", using the more direct dot notation.

2. It seems as if this could be used as a really nice Tuple. You can still call your members "Item1", "Item2" etc... but now you don't have to, it's also mutable, unlike a Tuple. This does have the huge drawback of lack of intellisense support.

3. You may be uncomfortable with "member names as strings", as is the feel with the dictionary, you may feel it is too like "executing strings", and it may lead to naming conventions getting coded in, and dealing with working with morphemes and syllables when code is trying understand how to use members :-P

4. Can you assign a value to an ExpandoObject itself or just it's members? Compare and contrast with dynamic/dynamic[], use whichever best suits your needs.

5. I don't think dynamic/dynamic[] works in a foreach loop, you have to use var, but possibly you can use ExpandoObject.

6. You cannot use dynamic as a data member in a class, perhaps because it's at least sort of like a keyword, hopefully you can with ExpandoObject.

7. I expect it "is" an ExpandoObject, might be useful to label very generic things apart, with code that differentiates based on types where there is lots of dynamic stuff being used.

Be nice if you could drill down multiple levels at once.

var e = new ExpandoObject();
e.position.x = 5;
etc...

Thats not the best possible example, imagine elegant uses as appropriate in your own projects.

It's a shame you cannot have code build some of these and push the results to intellisense. I'm not sure how this would work though.

Be nice if they could have a value as well as members.

var fifteen = new ExpandoObject();
fifteen = 15;
fifteen.tens = 1;
fifteen.units = 5;
fifteen.ToString() = "fifteen";
etc...

Try using this:-

mkdir -p dir;

NOTE:- This will also create any intermediate directories that don't exist; for instance,

Check out mkdir -p

or try this:-

if [[ ! -e $dir ]]; then
    mkdir $dir
elif [[ ! -d $dir ]]; then
    echo "$Message" 1>&2
fi

You can view loopback traffic live in Wireshark by having it read RawCap's output instantly. cmaynard describes this ingenious approach at the Wireshark forums. I will cite it here:

[...] if you want to view live traffic in Wireshark, you can still do it by running RawCap from one command-line and running Wireshark from another. Assuming you have cygwin's tail available, this could be accomplished using something like so:

cmd1: RawCap.exe -f 127.0.0.1 dumpfile.pcap

cmd2: tail -c +0 -f dumpfile.pcap | Wireshark.exe -k -i -

It requires cygwin's tail, and I could not find a way to do this with Windows' out-of-the-box tools. His approach works very fine for me and allows me to use all of Wiresharks filter capabilities on captured loopback traffic live.

Use const App instead of const app

If you are OK doing it periodically, you could run the following command to run it every 1 sec indefinitely. You can put other custom checks in place to run it n number of times.

watch -n 1 some_command

If you wish to have visual confirmation of changes, append --differences prior to the ls command.

According to the OSX man page, there's also

The --cumulative option makes highlighting "sticky", presenting a running display of all positions that have ever changed. The -t or --no-title option turns off the header showing the interval, command, and current time at the top of the display, as well as the following blank line.

Linux/Unix man page can be found here

Update: As suggested by a commenter (additional credit to How can I disable the spell checker on text inputs on the iPhone), use this to handle all desktop and mobile browsers.

<tag autocomplete="off" autocorrect="off" autocapitalize="off" spellcheck="false"/>

Original answer: Javascript cannot override user settings, so unless you use another mechanism other than textfields, this is not (or shouldn't be) possible.

I found Clover coverage tool which instruments code and highlights the code that is used and that is unused. Unlike Google CodePro Analytics, it also works for WebApplications (as per my experience and I may be incorrect about Google CodePro).

The only drawback that I noticed is that it does not takes Java interfaces into account.

Using strstr() or stristr() if your search should be case insensitive would be another option.

I have search for this problem and i got the following answers:

1. "C:\Program Files\Apache-tomcat-7.0.69\" remove the extra backslash (\)
2. Right click the log folder in tomcat folder and in security tab give this folder as a write-permission and then restart the net-beans as an run as administrator.

Your problem will be solved

SAP is really a big Company that offers incredible solutions oriented to medium-large companies.

Actually, I can say that the main IT products are: ERP, WEB, Human Resources, Integration, BI, Reports, Machine Learning, Mobile, Cloud, Robotics, and so on.

On the cloud, you can even find solutions using Cloud Foundry, NodeJS, HTML5, Java, etc.

It's really huge the solutions that offers to their customers.

select * from information_schema.columns
where table_schema = 'your_db'
order by table_name,ordinal_position

A solution in C# would be:

Helper class:

internal class DriverHelper
{

    private IWebDriver Driver { get; set; }
    private WebDriverWait Wait { get; set; }

    public DriverHelper(string driverUrl, int timeoutInSeconds)
    {
        Driver = new ChromeDriver();
        Driver.Url = driverUrl;
        Wait = new WebDriverWait(Driver, TimeSpan.FromSeconds(timeoutInSeconds));
    }

    internal bool ClickElement(string cssSelector)
    {
        //Find the element
        IWebElement element = Wait.Until(d=>ExpectedConditions.ElementIsVisible(By.CssSelector(cssSelector)))(Driver);
        return Wait.Until(c => ClickElement(element, cssSelector));
    }

    private bool ClickElement(IWebElement element, string cssSelector)
    {
        try
        {
            //Check if element is still included in the dom
            //If the element has changed a the OpenQA.Selenium.StaleElementReferenceException is thrown.
            bool isDisplayed = element.Displayed;

            element.Click();
            return true;
        }
        catch (StaleElementReferenceException)
        {
            //wait until the element is visible again
            element = Wait.Until(d => ExpectedConditions.ElementIsVisible(By.CssSelector(cssSelector)))(Driver);
            return ClickElement(element, cssSelector);
        }
        catch (Exception)
        {
            return false;
        }
    }
}

Invocation:

        DriverHelper driverHelper = new DriverHelper("http://www.seleniumhq.org/docs/04_webdriver_advanced.jsp", 10);
        driverHelper.ClickElement("input[value='csharp']:first-child");

Similarly can be used for Java.

I use Apache server, so I've used mod_proxy module. Enable modules:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

Then add:

ProxyPass /your-proxy-url/ http://service-url:serviceport/

Finally, pass proxy-url to your script.

The simplest solution would be a correlated sub select:

select
    A.*
from
    table_A A
where
    A.id in (
        select B.id from table_B B where B.tag = 'chair'
)

Alternatively you could join the tables and filter the rows you want:

select
    A.*
from
    table_A A
inner join table_B B
    on A.id = B.id
where
    B.tag = 'chair'

You should profile both and see which is faster on your dataset.

I have use this method

function getString()
{
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++)
{
    hash = hashes[i].split('=');
    vars.push(hash[0]);
    vars[hash[0]] = hash[1];
}
return vars;
}
var buisnessArea = getString();

Functional Component

Actually, for functional component the best practice is like below, I create a sample Spinner component:

import React from 'react';
import { ActivityIndicator } from 'react-native';
import { colors } from 'helpers/theme';
import type { FC } from 'types';

interface SpinnerProps {
  color?: string;
  size?: 'small' | 'large' | 1 | 0;
  animating?: boolean;
  hidesWhenStopped?: boolean;
}

const Spinner: FC<SpinnerProps> = ({
  color,
  size,
  animating,
  hidesWhenStopped,
}) => (
  <ActivityIndicator
    color={color}
    size={size}
    animating={animating}
    hidesWhenStopped={hidesWhenStopped}
  />
);

Spinner.defaultProps = {
  animating: true,
  color: colors.primary,
  hidesWhenStopped: true,
  size: 'small',
};

export default Spinner;

Try this one:

<body onload="imageRefreshBig();">

Also you might want to check Javascript console for errors (in Chrome it's under Shift + Ctrl + J).

$("#"+document.getElementById("<%= ButtonID.ClientID %>")).trigger("click");

The new ASP.NET Web API is a continuation of the previous WCF Web API project (although some of the concepts have changed).

WCF was originally created to enable SOAP-based services. For simpler RESTful or RPCish services (think clients like jQuery) ASP.NET Web API should be good choice.

For us, WCF is used for SOAP and Web API for REST. I wish Web API supported SOAP too. We are not using advanced features of WCF. Here is comparison from MSDN:

ASP.net Web API is all about HTTP and REST based GET,POST,PUT,DELETE with well know ASP.net MVC style of programming and JSON returnable; web API is for all the light weight process and pure HTTP based components. For one to go ahead with WCF even for simple or simplest single web service it will bring all the extra baggage. For light weight simple service for ajax or dynamic calls always WebApi just solves the need. This neatly complements or helps in parallel to the ASP.net MVC.

Check out the podcast : Hanselminutes Podcast 264 - This is not your father's WCF - All about the WebAPI with Glenn Block by Scott Hanselman for more information.

In the scenarios listed below you should go for WCF:

1. If you need to send data on protocols like TCP, MSMQ or MIME
2. If the consuming client just knows how to consume SOAP messages

WEB API is a framework for developing RESTful/HTTP services.

There are so many clients that do not understand SOAP like Browsers, HTML5, in those cases WEB APIs are a good choice.

HTTP services header specifies how to secure service, how to cache the information, type of the message body and HTTP body can specify any type of content like HTML not just XML as SOAP services.

Another option is to use one of my personal favorite CSS tools: box-shadow.

A box shadow is really a drop-shadow on the node. It looks like this:

-moz-box-shadow: 1px 2px 3px rgba(0,0,0,.5);
-webkit-box-shadow: 1px 2px 3px rgba(0,0,0,.5);
box-shadow: 1px 2px 3px rgba(0,0,0,.5);

The arguments are:

1px: Horizontal offset of the effect. Positive numbers shift it right, negative left.
2px: Vertical offset of the effect. Positive numbers shift it down, negative up.
3px: The blur effect.  0 means no blur.
color: The color of the shadow.

So, you could leave your current design, and add a box-shadow like:

box-shadow: 0px -2px 2px rgba(34,34,34,0.6);

This should give you a 'blurry' top-edge.

This website will help with more information: http://css-tricks.com/snippets/css/css-box-shadow/

Or use this

- (void)insertSubview:(UIView *)view belowSubview:(UIView*)siblingSubview;

as per here

The pointer-events CSS property is a little lacking when it comes to support (caniuse.com), but it's very succinct:

.my-link { pointer-events: none; } 

In case you have to replace multiple values and if you don't mind "refactoring" your variable with as.factor(as.character(...)) you could try the following:

replace.values <- function(search, replace, x){
  stopifnot(length(search) == length(replace))
  xnew <- replace[ match(x, search) ]
  takeOld <- is.na(xnew) & !is.na(x)
  xnew[takeOld] <- x[takeOld]
  return(xnew)
}

iris$Species <- as.factor(search=c("oldValue1","oldValue2"),
                          replace=c("newValue1","newValue2"),
                          x=as.character(iris$Species))

I know this might sound silly, but I recently came across this myself, Make sure the domain controller is not read-only.

You can use pandas dataframes or series as Julien said but if you want to restrict your-self to numpy you can pass an additional array of indices:

from sklearn.model_selection import train_test_split
import numpy as np
n_samples, n_features, n_classes = 10, 2, 2
data = np.random.randn(n_samples, n_features)  # 10 training examples
labels = np.random.randint(n_classes, size=n_samples)  # 10 labels
indices = np.arange(n_samples)
x1, x2, y1, y2, idx1, idx2 = train_test_split(
    data, labels, indices, test_size=0.2)

Here's the very minimum you need to get data out of a MySQL database:

Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection conn = DriverManager.getConnection
   ("jdbc:mysql://localhost:3306/foo", "root", "password");

Statement stmt = conn.createStatement();
stmt.execute("SELECT * FROM `FOO.BAR`");
stmt.close();
conn.close();

Add exception handling, configuration etc. to taste.

They are synonyms, no difference at all.Decimal and Numeric data types are numeric data types with fixed precision and scale.

-- Initialize a variable, give it a data type and an initial value

declare @myvar as decimal(18,8) or numeric(18,8)----- 9 bytes needed

-- Increse that the vaue by 1

set @myvar = 123456.7

--Retrieve that value

select @myvar as myVariable

You can try ScrollableStackView : https://github.com/gurhub/ScrollableStackView

It's Objective-C and Swift compatible library. It's available through CocoaPods.

Sample Code (Swift)

import ScrollableStackView

var scrollable = ScrollableStackView(frame: view.frame)
view.addSubview(scrollable)

// add your views with 
let rectangle = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 55))
rectangle.backgroundColor = UIColor.blue
scrollable.stackView.addArrangedSubview(rectangle)
// ...

Sample Code (Objective-C)

@import ScrollableStackView

ScrollableStackView *scrollable = [[ScrollableStackView alloc] initWithFrame:self.view.frame];
scrollable.stackView.distribution = UIStackViewDistributionFillProportionally;
scrollable.stackView.alignment = UIStackViewAlignmentCenter;
scrollable.stackView.axis = UILayoutConstraintAxisVertical;
[self.view addSubview:scrollable];

UIView *rectangle = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 55)];
[rectangle setBackgroundColor:[UIColor blueColor]];

// add your views with

I know this an old thread, but I found out using the Subtotal method in VBA also accurately renders a count of the rows. The formula I found is in this article, and looks like this:

Application.WorksheetFunction.Subtotal(2, .Range("A2:A" & .Rows(.Rows.Count).End(xlUp).Row))

I tested it and it came out accurately every time, rendering the correct number of visible rows in column A.

Hopefully this will help some other wayfarer of the 'Net like me.

You may try:

    $('#GridName').data('kendoGrid').dataSource.read();
$('#GridName').data('kendoGrid').refresh();

Another possibility would be the use of REGEXP_SUBSTR.

HTML5 adds a maxlength attribute to the textarea element, like so:

<!DOCTYPE html>
<html>
    <body>
        <form action="processForm.php" action="post">
            <label for="story">Tell me your story:</label><br>
            <textarea id="story" maxlength="100"></textarea>
            <input type="submit" value="Submit">
        </form>
    </body>
</html>

This is currently supported in Chrome 13, FF 5, and Safari 5. Not surprisingly, this is not supported in IE 9. (Tested on Win 7)

In case somebody still needs

android:gravity="end"

First create the duplicate database:

CREATE DATABASE duplicateddb;

Make sure the user and permissions are all in place and:

 mysqldump -u admin -p originaldb | mysql -u backup -pPassword duplicateddb; 

I loved the FireFox Header Spy extension so much that i built a HTTP Spy extension for Chrome. I used to use the developer tools too for debugging headers, but now my life is so much better.

Here is a Chrome extension that allows you to view request-, response headers and cookies without any extra clicks right after the page is loaded.

It also handles redirects. It comes with an unobtrusive micro-mode that only shows a hand picked selection of response headers and a normal mode that shows all the information.

You can use EasyDict library ^(doc):

EasyDict allows to access dict values as attributes (works recursively). A Javascript-like properties dot notation for python dicts.

USEAGE

>>> from easydict import EasyDict as edict
>>> d = edict({'foo':3, 'bar':{'x':1, 'y':2}})
>>> d.foo
3
>>> d.bar.x
1

>>> d = edict(foo=3)
>>> d.foo
3

[INSTALLATION]:

• pip install easydict

Here is a work around but not always a great one, depending on how much you scale it. Explanation can be found here: https://www.geekgoddess.com/how-to-resize-the-google-nocaptcha-recaptcha/

.g-recaptcha {
    transform:scale(0.77);
    transform-origin:0 0;
}

UPDATE: Google has added support for a smaller size via a parameter. Have a look at the docs - https://developers.google.com/recaptcha/docs/display#render_param

This error can also show up if there are parts in your string that json.loads() does not recognize. An in this example string, an error will be raised at character 27 (char 27).

string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""

My solution to this would be to use the string.replace() to convert these items to a string:

import json

string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""

string = string.replace("False", '"False"')

dict_list = json.loads(string)

string[] lines = text.Split(
  Environment.NewLine.ToCharArray(), 
  StringSplitOptions.RemoveEmptyStrings);

The RemoveEmptyStrings option will make sure you don't have empty entries due to \n following a \r

(Edit to reflect comments:) Note that it will also discard genuine empty lines in the text. This is usually what I want but it might not be your requirement.

This formula seems more intuitive to me:

=SUBSTITUTE(A1,"SomeText","") <> A1

this returns TRUE if "SomeText" is contained within A1.

The IsNumber/Search and IsError/Find formulas mentioned in the other answers certainly do work, but I always find myself needing to look at the help or experimenting in Excel too often with those ones.

The accepted answer will not return files prefix with a . To do that use

for entry in "$search_dir"/* "$search_dir"/.[!.]* "$search_dir"/..?*
do
  echo "$entry"
done

Description

You should do this using jQuery.ajaxStart and jQuery.ajaxStop.

1. Create a div with your image
2. Make it visible in jQuery.ajaxStart
3. Hide it in jQuery.ajaxStop

Sample

<div id="loading" style="display:none">Your Image</div>

<script src="../../Scripts/jquery-1.5.1.min.js" type="text/javascript"></script>
<script>
    $(function () {
        var loading = $("#loading");
        $(document).ajaxStart(function () {
            loading.show();
        });

        $(document).ajaxStop(function () {
            loading.hide();
        });

        $("#startAjaxRequest").click(function () {
            $.ajax({
                url: "http://www.google.com",
                // ... 
            });
        });
    });
</script>

<button id="startAjaxRequest">Start</button>

What one program writes to stdout can be read by another via stdin. So simply, using c, write prog1 to print something using printf() and prog2 to read something using scanf(). Then just run

./prog1 | ./prog2

Maybe something like this:

sed 's/ab/~~/g; s/bc/ab/g; s/~~/bc/g'

Replace ~ with a character that you know won't be in the string.

Suppose this is your json

{
  "date":"11/05/2016",
  "venue": "{\"ID\":12,\"CITY\":Delhi}"
}

if you again want deserialize venue, modify json as below

{
  "date":"11/05/2016",
  "venue": "{\"ID\":\"12\",\"CITY\":\"Delhi\"}"
}

then try to deserialize to respective class by taking the value of venue

This is not possible from HTML on. The closest what you can get is the accept-charset attribute of the <form>. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.

To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).

Update: Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.

The workaround is

1. search and replace \r\n to thisismynewlineword

(this will remove all the new lines and there should be whole one line)

1. now perform your replacements

2. search and replace thisismynewlineword to \r\n

(to undo the step 1)
