First you can use a Paginator. This is as simple as:

$allUsers = User::paginate(15);

$someUsers = User::where('votes', '>', 100)->paginate(15);

The variables will contain an instance of Paginator class. all of your data will be stored under data key.

Or you can do something like:

Old versions Laravel.

Model::all()->take(10)->get();

Newer version Laravel.

Model::all()->take(10);

The underlying problem here is the 1st level cache of JPA. From the JPA spec Version 2.2 section 3.1. emphasise is mine:

An EntityManager instance is associated with a persistence context. A persistence context is a set of entity instances in which for any persistent entity identity there is a unique entity instance.

This is important because JPA tracks changes to that entity in order to flush them to the database. As a side effect it also means within a single persistence context an entity gets only loaded once. This why reloading the changed entity doesn't have any effect.

You have a couple of options how to handle this:

1. Evict the entity from the EntityManager. This may be done by calling EntityManager.detach, annotating the updating method with @Modifying(clearAutomatically = true) which evicts all entities. Make sure changes to these entities get flushed first or you might end up loosing changes.

2. Use EntityManager.refresh().

3. Use a different persistence context to load the entity. The easiest way to do this is to do it in a separate transaction. With Spring this can be done by having separate methods annotated with @Transactional on beans called from a bean not annotated with @Transactional. Another way is to use a TransactionTemplate which works especially nicely in tests where it makes transaction boundaries very visible.

There is one more option now ( January-2015 )

1. Create a new private repo
2. On the empty repo screen there is an "import" option/button
3. click it and put the existing github repo url There is no github option mention but it works with github repos too.
4. DONE

Put your JavaScript code after your tag <canvas></canvas>

For some reason I kept having this full page width problem with IE7 so I made this hack:

var tag = $("<div></div>");
//IE7 workaround
var w;
if (navigator.appVersion.indexOf("MSIE 7.") != -1)
    w = 400;
else
    w = "auto";

tag.html('My message').dialog({
    width: w,
    maxWidth: 600,
    ...

typeof(MyType).GetField("fieldName", BindingFlags.NonPublic | BindingFlags.Instance)

Removing the focus after the cell value changes allow the values to update in the DataGridView. Remove the focus by setting the CurrentCell to null.

private void DataGridView1OnCellValueChanged(object sender, DataGridViewCellEventArgs dataGridViewCellEventArgs)
{
    // Remove focus
    dataGridView1.CurrentCell = null;
    // Put in updates
    Update();
}

private void DataGridView1OnCurrentCellDirtyStateChanged(object sender, EventArgs eventArgs)
{
    if (dataGridView1.IsCurrentCellDirty)
    {
        dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit);
    }

}

TextWatcher is a bit verbose for my taste, so I made something a bit easier to swallow:

public abstract class TextValidator implements TextWatcher {
    private final TextView textView;

    public TextValidator(TextView textView) {
        this.textView = textView;
    }

    public abstract void validate(TextView textView, String text);

    @Override
    final public void afterTextChanged(Editable s) {
        String text = textView.getText().toString();
        validate(textView, text);
    }

    @Override
    final public void beforeTextChanged(CharSequence s, int start, int count, int after) { /* Don't care */ }

    @Override
    final public void onTextChanged(CharSequence s, int start, int before, int count) { /* Don't care */ }
}

Just use it like this:

editText.addTextChangedListener(new TextValidator(editText) {
    @Override public void validate(TextView textView, String text) {
       /* Validation code here */
    }
});

You might want to do this when you obtain data as objects from databases:

// Suppose 'result' is the end product from some query $query

$result = $mysqli->query($query);
$result = db_result_to_array($result);

function db_result_to_array($result)
{
    $res_array = array();

    for ($count=0; $row = $result->fetch_assoc(); $count++)
        $res_array[$count] = $row;

    return $res_array;
}

I got a solution!

When resetting root password at step 2), also change the auth plugin to mysql_native_password:

use mysql;
update user set authentication_string=PASSWORD("") where User='root';
update user set plugin="mysql_native_password" where User='root';  # THIS LINE

flush privileges;
quit;

This allowed me to log in successfully!

Full code solution

1. run bash commands

1. first, run these bash commands

sudo /etc/init.d/mysql stop # stop mysql service
sudo mysqld_safe --skip-grant-tables & # start mysql without password
# enter -> go
mysql -uroot # connect to mysql

2. then run mysql commands => copy paste this to cli manually

use mysql; # use mysql table
update user set authentication_string=PASSWORD("") where User='root'; # update password to nothing
update user set plugin="mysql_native_password" where User='root'; # set password resolving to default mechanism for root user

flush privileges;
quit;

3. run more bash commands

sudo /etc/init.d/mysql stop 
sudo /etc/init.d/mysql start # reset mysql
# try login to database, just press enter at password prompt because your password is now blank
mysql -u root -p 

4. Socket issue (from your comments)

When you see a socket error, a community came with 2 possible solutions:

sudo mkdir -p /var/run/mysqld; sudo chown mysql /var/run/mysqld
sudo mysqld_safe --skip-grant-tables &

(thanks to @Cerin)

Or

mkdir -p /var/run/mysqld && chown mysql:mysql /var/run/mysqld  

(thanks to @Peter Dvukhrechensky)

Blind paths and possible edge errors

Use 127.0.0.1 instead of localhost

mysql -uroot # "-hlocalhost" is default

Can lead to "missing file" or slt error.

mysql -uroot -h127.0.0.1

Works better.

Skip the socket issue

I've found many ways to create mysqld.sock file, change access rights or symlink it. It was not the issue after all.

Skip the my.cnf file

The issue also was not there. If you are not sure, this might help you.

A little late but..

A more simple way would be to add a dummy data item to the list with parameter IsDummy=true and make sure it is not HitTestVisable and its hight is 1 pixel (using a Converter) so it wont be seen.

Than just register to SelectionChanged and in it, set the index to the dummy item index.

It works like a charm and this way you don't mess with the style and colors of the ComboBox or your application theme.

Suppose the two segments have endpoints A,B and C,D. The numerically robust way to determine intersection is to check the sign of the four determinants:

| Ax-Cx  Bx-Cx |    | Ax-Dx  Bx-Dx |
| Ay-Cy  By-Cy |    | Ay-Dy  By-Dy |

| Cx-Ax  Dx-Ax |    | Cx-Bx  Dx-Bx |
| Cy-Ay  Dy-Ay |    | Cy-By  Dy-By |

For intersection, each determinant on the left must have the opposite sign of the one to the right, but there need not be any relationship between the two lines. You are basically checking each point of a segment against the other segment to make sure they lie on opposite sides of the line defined by the other segment.

See here: http://www.cs.cmu.edu/~quake/robust.html

If you need to concatenate paths with quotes, you can use = to replace quotes in a variable. This does not require you to know if the path already contains quotes or not. If there are no quotes, nothing is changed.

@echo off
rem Paths to combine
set DIRECTORY="C:\Directory with spaces"
set FILENAME="sub directory\filename.txt"

rem Combine two paths
set COMBINED="%DIRECTORY:"=%\%FILENAME:"=%"
echo %COMBINED%

rem This is just to illustrate how the = operator works
set DIR_WITHOUT_SPACES=%DIRECTORY:"=%
echo %DIR_WITHOUT_SPACES%

Try adding this:

$mail->SMTPAuth   = true;
$mail->SMTPSecure = "tls";

By looking at your debug logs, you can notice that the failing PhpMailer log shows this:

(..snip..)
SMTP -> ERROR: AUTH not accepted from server: 250 orion.bommtempo.net.br Hello admin-teste.bommtempo.com.br [200.155.129.6]
(..snip..)
503 AUTH command used when not advertised
(..snip..)

While your successful PEAR log shows this:

DEBUG: Send: STARTTLS
DEBUG: Recv: 220 TLS go ahead

My guess is that explicitly asking PHPMailer to use TLS will put it on the right track.
Also, make sure you're using the latest versin of PHPMailer.

You have to initialise the object (create the object itself) in order to be able to call its methods otherwise you would get a NullPointerException.

WordList words = new WordList();

There's a better way of storing JSON in the HTML:

HTML

<script id="some-data" type="application/json">{"param_1": "Value 1", "param_2": "Value 2"}</script>

JavaScript

JSON.parse(document.getElementById('some-data').textContent);

On the one hand you could use sp_executesql:

exec sp_executesql N'select @rowcount=count(*) from anytable', 
                    N'@rowcount int output', @rowcount output;

On the other hand you could use a temporary table:

declare @result table ([rowcount] int);
insert into @result ([rowcount])
exec (N'select count(*) from anytable');
declare @rowcount int = (select top (1) [rowcount] from @result);

Example to download with wget on server a big file link that can be obtained in your browser.

In example using Google Chrome.

Login where you need, and press download. Go to download and copy your link.

Then open DevTools on a page where you where login, go to Console and get your cookies, by entering document.cookie

Now, go to server and download your file: wget --header "Cookie: <YOUR_COOKIE_OUTPUT_FROM_CONSOLE>" <YOUR_DOWNLOAD_LINK>

There's multiple ways of doing things in batch, so if escaping with a double percent %% isn't working for you, then you could try something like this:

set olddir=%CD%
cd /d "path of folder"
del "file name/ or *.txt etc..."
cd /d "%olddir%"

How this works:

set olddir=%CD% sets the variable "olddir" or any other variable name you like to the directory your batch file was launched from.

cd /d "path of folder" changes the current directory the batch will be looking at. keep the quotations and change path of folder to which ever path you aiming for.

del "file name/ or *.txt etc..." will delete the file in the current directory your batch is looking at, just don't add a directory path before the file name and just have the full file name or, to delete multiple files with the same extension with *.txt or whatever extension you need.

cd /d "%olddir%" takes the variable saved with your old path and goes back to the directory you started the batch with, its not important if you don't want the batch going back to its previous directory path, and like stated before the variable name can be changed to whatever you wish by changing the set olddir=%CD% line.

you can apply css an an object. So you can define your object in your javascript like this:

var my_css_class = { backgroundColor : 'blue', color : '#fff' };

And then simply apply it to all the elements you want

$("#myelement").css(my_css_class);

So it is reusable. What purpose would you do this for though?

In my case, static fields will not be injected.

Another way is:

$('#element').attr('value', '');

This is only a warning: your code still works, but probably won't work in the future as the method is deprecated. See the relevant source of Chromium and corresponding patch.

This has already been recognised and fixed in jQuery 1.11 (see here and here).

Default Values

• Occurrence constraints minOccurs and maxOccurs default to 1.

Common Cases Explained

<xsd:element name="A"/>

means A is required and must appear exactly once.

<xsd:element name="A" minOccurs="0"/>

means A is optional and may appear at most once.

 <xsd:element name="A" maxOccurs="unbounded"/>

means A is required and may repeat an unlimited number of times.

 <xsd:element name="A" minOccurs="0" maxOccurs="unbounded"/>

means A is optional and may repeat an unlimited number of times.

• W3C XML Schema Part 0: Primer

  In general, an element is required to appear when the value of minOccurs is 1 or more. The maximum number of times an element may appear is determined by the value of a maxOccurs attribute in its declaration. This value may be a positive integer such as 41, or the term unbounded to indicate there is no maximum number of occurrences. The default value for both the minOccurs and the maxOccurs attributes is 1. Thus, when an element such as comment is declared without a maxOccurs attribute, the element may not occur more than once. Be sure that if you specify a value for only the minOccurs attribute, it is less than or equal to the default value of maxOccurs, i.e. it is 0 or 1. Similarly, if you specify a value for only the maxOccurs attribute, it must be greater than or equal to the default value of minOccurs, i.e. 1 or more. If both attributes are omitted, the element must appear exactly once.

    maxOccurs = (nonNegativeInteger | unbounded)  : 1

Here's the simplest solution (Jibwa made it seem complicated in another answer), without having to generate indices yourself - just using the ShuffleSplit object to generate 1 split.

import numpy as np 
from sklearn.model_selection import ShuffleSplit # or StratifiedShuffleSplit
sss = ShuffleSplit(n_splits=1, test_size=0.1)

data_size = 100
X = np.reshape(np.random.rand(data_size*2),(data_size,2))
y = np.random.randint(2, size=data_size)

sss.get_n_splits(X, y)
train_index, test_index = next(sss.split(X, y)) 

X_train, X_test = X[train_index], X[test_index] 
y_train, y_test = y[train_index], y[test_index]

Tom's answer is quite detailed and exhaustive but you may also be interested in this simple study about Parquet vs Avro done at Allstate Insurance, summarized here:

"Overall, Parquet showed either similar or better results on every test [than Avro]. The query-performance differences on the larger datasets in Parquet’s favor are partly due to the compression results; when querying the wide dataset, Spark had to read 3.5x less data for Parquet than Avro. Avro did not perform well when processing the entire dataset, as suspected."

You can do it programatically:

        // remove title

            WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.main);
    }
}

Or you can do it via your AndroidManifest.xml file:

There is an important technical difference between race conditions and data races. Most answers seem to make the assumption that these terms are equivalent, but they are not.

A data race occurs when 2 instructions access the same memory location, at least one of these accesses is a write and there is no happens before ordering among these accesses. Now what constitutes a happens before ordering is subject to a lot of debate, but in general ulock-lock pairs on the same lock variable and wait-signal pairs on the same condition variable induce a happens-before order.

A race condition is a semantic error. It is a flaw that occurs in the timing or the ordering of events that leads to erroneous program behavior.

Many race conditions can be (and in fact are) caused by data races, but this is not necessary. As a matter of fact, data races and race conditions are neither the necessary, nor the sufficient condition for one another. This blog post also explains the difference very well, with a simple bank transaction example. Here is another simple example that explains the difference.

Now that we nailed down the terminology, let us try to answer the original question.

Given that race conditions are semantic bugs, there is no general way of detecting them. This is because there is no way of having an automated oracle that can distinguish correct vs. incorrect program behavior in the general case. Race detection is an undecidable problem.

On the other hand, data races have a precise definition that does not necessarily relate to correctness, and therefore one can detect them. There are many flavors of data race detectors (static/dynamic data race detection, lockset-based data race detection, happens-before based data race detection, hybrid data race detection). A state of the art dynamic data race detector is ThreadSanitizer which works very well in practice.

Handling data races in general requires some programming discipline to induce happens-before edges between accesses to shared data (either during development, or once they are detected using the above mentioned tools). this can be done through locks, condition variables, semaphores, etc. However, one can also employ different programming paradigms like message passing (instead of shared memory) that avoid data races by construction.

It has copy, and as stated the JDK already has move.

Don't implement your own copy method. There are so many floating out there...

brew -v or brew --version does the trick!

With tr:

# Converts upper to lower case 
$ tr '[:upper:]' '[:lower:]' < input.txt > output.txt

# Converts lower to upper case
$ tr '[:lower:]' '[:upper:]' < input.txt > output.txt

Or, sed on GNU (but not BSD or Mac as they don't support \L or \U):

# Converts upper to lower case
$ sed -e 's/\(.*\)/\L\1/' input.txt > output.txt

# Converts lower to upper case
$ sed -e 's/\(.*\)/\U\1/' input.txt > output.txt
 

This is a nasty one... mysterious error and no clear fix.

update/revert/commit did NOT work in my situation. I hadn't done anything weird - just some svn moves.

What DID work for me was:

svn remove offender
svn commit
cd ..
rm -fR parent
svn up parent
cd parent
svn remove offender again
svn commit
copy offender back in (minus .svn dirs)
svn add
svn commit

Weird to say the least. Basically, the svn remove --force offender wasn't doing completely removing for some reason. Which is sort of what the error message was saying. Only by removing the parent, then updating the parent, did this become obvious because then the offender reappeared! svn removing offender again then properly removed it.

In case you are using WordPress you can simply use

    add_query_args(['sort' => 'asc'], 'http:/example.com/?search=news')

Docs https://developer.wordpress.org/reference/functions/add_query_arg/

Try this:

body {
  background-image:url(img/background.jpg);
  background-repeat: no-repeat;
  min-height: 679px;
  background-size: cover;
}

You can use a Java COM bridge like JACOB. If it is from client side, another option would be to use Javascript.

I don't know what language you're using, but .NET has the environment variable PROCESSOR_ARCHITEW6432 if the OS is 64-bit.

If all you want to know is whether your application is running 32-bit or 64-bit, you can check IntPtr.Size. It will be 4 if running in 32-bit mode and 8 if running in 64-bit mode.

I faced this problem and finally resolved. Please make sure that your web.xml and Servlet.xml file should present in web/inf folder.

Do not forget to verify if your text editor encodes properly your code in UTF-8.

Otherwise, you may have invisible characters that are not interpreted as UTF-8.

Use a docstring, as others have already written.

You can even go one step further and add a doctest to your docstring, making automated testing of your functions a snap.

Use the following code to obtain the version of R packages installed in the system:

installed.packages(fields = c ("Package", "Version"))

Try running fuser command

/home: root 2919 f.... automount

[root@guest2 ~]# kill -9 2919

autofs service is known to cause this issue.

You can use command

#service autofs stop

And try again.

You need to commit or destroy any unsaved changes before you switch branch.

Git won't let you switch branch if it means unsaved changes would be removed.

There is a long history of the .NET file enumeration methods being slow. The issue is there is not an instantaneous way of enumerating large directory structures. Even the accepted answer here has its issues with GC allocations.

The best I've been able to do is wrapped up in my library and exposed as the FindFile (source) class in the CSharpTest.Net.IO namespace. This class can enumerate files and folders without unneeded GC allocations and string marshalling.

The usage is simple enough, and the RaiseOnAccessDenied property will skip the directories and files the user does not have access to:

    private static long SizeOf(string directory)
    {
        var fcounter = new CSharpTest.Net.IO.FindFile(directory, "*", true, true, true);
        fcounter.RaiseOnAccessDenied = false;

        long size = 0, total = 0;
        fcounter.FileFound +=
            (o, e) =>
            {
                if (!e.IsDirectory)
                {
                    Interlocked.Increment(ref total);
                    size += e.Length;
                }
            };

        Stopwatch sw = Stopwatch.StartNew();
        fcounter.Find();
        Console.WriteLine("Enumerated {0:n0} files totaling {1:n0} bytes in {2:n3} seconds.",
                          total, size, sw.Elapsed.TotalSeconds);
        return size;
    }

For my local C:\ drive this outputs the following:

Enumerated 810,046 files totaling 307,707,792,662 bytes in 232.876 seconds.

Your mileage may vary by drive speed, but this is the fastest method I've found of enumerating files in managed code. The event parameter is a mutating class of type FindFile.FileFoundEventArgs so be sure you do not keep a reference to it as it's values will change for each event raised.

    return Convert.ToInt64((date.ToUniversalTime() - epoch).TotalSeconds);
}

Should use ToUniversalTime() for the DateTime object.

I'd recommend using NSString for strings that you want to manipulate. Actually come to think of it as a developer I've never run into a problem with NSString that Swift String would solve... I understand the subtleties. But I've yet to have an actual need for them.

var foo = someSwiftString as NSString

or

var foo = "Foo" as NSString

or

var foo: NSString = "blah"

And then the whole world of simple NSString string operations is open to you.

As answer to the question

// check bounds before you do this, e.g. foo.length > 0
// Note shortFoo is of type NSString
var shortFoo = foo.substringToIndex(foo.length-1)

if you happen to not have a graphical interface available you can also print out the commit graph on the command line:

git log --oneline --graph --decorate --all

if this command complains with an invalid option --oneline, use:

git log --pretty=oneline --graph --decorate --all

Semantically speaking, a p is a paragraph tag and should be used to format a paragraph of text. A span is an inline formatting change that isn't handled semantically.

You are not doing error checking after the call to mysql_query:

$result = mysql_query("SELECT * FROM student WHERE IDNO=".$_GET['id']);
if (!$result) { // add this check.
    die('Invalid query: ' . mysql_error());
}

In case mysql_query fails, it returns false, a boolean value. When you pass this to mysql_fetch_array function (which expects a mysql result object) we get this error.

You use the modf function:

double integral;
double fractional = modf(some_double, &integral);

You can also cast it to an integer, but be warned you may overflow the integer. The result is not predictable then.

Using aggregate function like below :

[
{$group: {_id : {book : '$book',address:'$addr'}, total:{$sum :1}}},
{$project : {book : '$_id.book', address : '$_id.address', total : '$total', _id : 0}}
]

it will give you result like following :

        {
            "total" : 1,
            "book" : "book33",
            "address" : "address90"
        }, 
        {
            "total" : 1,
            "book" : "book5",
            "address" : "address1"
        }, 
        {
            "total" : 1,
            "book" : "book99",
            "address" : "address9"
        }, 
        {
            "total" : 1,
            "book" : "book1",
            "address" : "address5"
        }, 
        {
            "total" : 1,
            "book" : "book5",
            "address" : "address2"
        }, 
        {
            "total" : 1,
            "book" : "book3",
            "address" : "address4"
        }, 
        {
            "total" : 1,
            "book" : "book11",
            "address" : "address77"
        }, 
        {
            "total" : 1,
            "book" : "book9",
            "address" : "address3"
        }, 
        {
            "total" : 1,
            "book" : "book1",
            "address" : "address15"
        }, 
        {
            "total" : 2,
            "book" : "book1",
            "address" : "address2"
        }, 
        {
            "total" : 3,
            "book" : "book1",
            "address" : "address1"
        }

I didn't quite get your expected result format, so feel free to modify this to one you need.

What if you want to select just a few?

No problem, first:

1. Ctrl+F find the letters by typing them
2. ESC to quit searching (you need to this even when using Ctrl+Shift+L to select all occurences)

OR

1. just select those letters with your mouse or keyboard (Shift+arrows)

Now that the mouse cursor is blinking on your first selection, using a few more Key Bindings (thanks for the ref j08691) you may:

• Ctrl+D select the next occurrence
• Ctrl+K+Ctrl+D skip the next occurrence
• Ctrl+U undo one of the above

There is one more thing you should be aware of - MIME.

If you need to use a MIME type and it isn't supported by default, you can register your own handlers in config/initializers/mime_types.rb:

Mime::Type.register "text/markdown", :markdown

(string)((int)"00000234892839")

When creating your own library, you can can create *.d.ts files by using the tsc (TypeScript Compiler) command like so: (assuming you're building your library to the dist/lib folder)

tsc -d --declarationDir dist/lib --declarationMap --emitDeclarationOnly

• -d (--declaration): generates the *.d.ts files
• --declarationDir dist/lib: Output directory for generated declaration files.
• --declarationMap: Generates a sourcemap for each corresponding ‘.d.ts’ file.
• --emitDeclarationOnly: Only emit ‘.d.ts’ declaration files. (no compiled JS)

(see the docs for all command line compiler options)

Or for instance in your package.json:

"scripts": {
    "build:types": "tsc -d --declarationDir dist/lib --declarationMap --emitDeclarationOnly",
}

and then run: yarn build:types (or npm run build:types)

The particular format for strptime:

datetime.datetime.strptime(string_date, "%Y-%m-%d %H:%M:%S.%f")
#>>> datetime.datetime(2013, 9, 28, 20, 30, 55, 782000)

You can reset the plot by doing this:

dev.off()

I had a similar issue when trying to migrate a Drupal website from one local host to another. From Mac running XAMMP to Windows running WAMP.

This was the error message I kept getting when trying to access the pages of the website.

PDOException: SQLSTATE[HY000] [2002] No connection could be made because the target machine actively refused it. 
in drupal_get_installed_schema_version() (line 155 of C:\wamp\www\chia\includes\install.inc).

In settings.php, I've changed everything correctly, database name, user and password.

$databases = array (
  'default' => 
  array (
    'default' => 
    array (
      'database' => 'mydatabasename',
      'username' => 'mydbusername',
      'password' => 'mydbpass',
      'host' => 'localhost',
      'port' => '8889',
      'driver' => 'mysql',
      'prefix' => '',
    ),
  ),
);

After a couple of hours of mindless google searching I've changed the port to a empty value:

'port' => '',

And after that the site loaded properly.

If you're live watching if unloading class worked in JConsole or something, try also adding java.lang.System.gc() at the end of your class unloading logic. It explicitly triggers Garbage Collector.

I hate to admit how little I've done an iPhone app for, but I can tell you I won't be doing that again. The guy who said that "simple, one function apps can be done .. [by solo developers]... for $5K" is correct; however, that is still lowball, and presumes almost no project design, graphic design or network backend work.

one line version: (i is an old dictionary, p is a reversed dictionary)

explanation : i.keys() and i.values() returns two lists with keys and values of the dictionary respectively. The zip function has the ability to tie together lists to produce a dictionary.

p = dict(zip(i.values(),i.keys()))

Warning : This will work only if the values are hashable and unique.

is there a possibility that casting a double created via Math.round() will still result in a truncated down number

No, round() will always round your double to the correct value, and then, it will be cast to an long which will truncate any decimal places. But after rounding, there will not be any fractional parts remaining.

Here are the docs from Math.round(double):

Returns the closest long to the argument. The result is rounded to an integer by adding 1/2, taking the floor of the result, and casting the result to type long. In other words, the result is equal to the value of the expression:

(long)Math.floor(a + 0.5d)

You can use the function last_insert_rowid():

The last_insert_rowid() function returns the ROWID of the last row insert from the database connection which invoked the function. The last_insert_rowid() SQL function is a wrapper around the sqlite3_last_insert_rowid() C/C++ interface function.

To select between the single quotes I usually do a vi' ("select inner single quotes").

Inside a parenthesis block, I use vib ("select inner block")

Inside a curly braces block you can use viB ("capital B")

To make the selections "inclusive" (select also the quotes, parenthesis or braces) you can use a instead of i.

You can read more about the Text object selections on the manual, or :help text-objects within vim.

I found this solution.I download JDK 8.Then I add downloading jdk file path name of JAVA_HOME into user variables in environment variable.

If your Exchange server is configured to support POP or IMAP, that's an easy way out.

Another option is WebDAV access. there is a library available for that. This might be your best option.

I think there are options using COM objects to access Exchange, but I'm not sure how easy it is.

It all depends on what exactly your administrator is willing to give you access to I guess.

If you wanted to search some elements based on a regex, you can use the filter function. For example, say you wanted to make sure that in all the input boxes, the user has only entered numbers, so let's find all the inputs which don't match and highlight them.

$("input:text")
    .filter(function() {
        return this.value.match(/[^\d]/);
    })
    .addClass("inputError")
;

Of course if it was just something like this, you could use the form validation plugin, but this method could be applied to any sort of elements you like. Another example to show what I mean: Find all the elements whose id matches /[a-z]+_\d+/

$("[id]").filter(function() {
    return this.id.match(/[a-z]+_\d+/);
});

Visual select the text, then U for uppercase or u for lowercase. To swap all casing in a visual selection, press ~ (tilde).

Without using a visual selection, gU<motion> will make the characters in motion uppercase, or use gu<motion> for lowercase.

For more of these, see Section 3 in Vim's change.txt help file.

I usually like to have the following:

• bin (Binaries)
• doc (Documents)
• inf (Information)
• lib (Libraries)
• res (Resources)
• src (Source)
• tst (Test)

These may be considered unconventional, but I find it to be a very nice way to organize things.

UTF-8 doesn't work for me in office 2007 without any service pack, with or without BOM (U+ffef or 0xEF,0xBB,0xBF , neither works) installing sp3 makes UTF-8 work when 0xEF,0xBB,0xBF BOM is prepended.

UTF-16 works when encoding in python using "utf-16-le" with a 0xff 0xef BOM prepended, and using tab as seperator. I had to manually write out the BOM, and then use "utf-16-le" rather then "utf-16", otherwise each encode() prepended the BOM to every row written out which appeared as garbage on the first column of the second line and after.

can't tell whether UTF-16 would work without any sp installed, since I can't go back now. sigh

This is on windows, dunno about office for MAC.

for both working cases, the import works when launching a download directly from the browser and the text import wizard doesn't intervence, it works like you would expect.

Below is a copy-pasteable implementation of Michael Freidgeim's answer

function Delete-FolderAndContents {
    # http://stackoverflow.com/a/9012108

    param(
        [Parameter(Mandatory=$true, Position=1)] [string] $folder_path
    )

    process {
        $child_items = ([array] (Get-ChildItem -Path $folder_path -Recurse -Force))
        if ($child_items) {
            $null = $child_items | Remove-Item -Force -Recurse
        }
        $null = Remove-Item $folder_path -Force
    }
}

Don't use an array - use a generic List<T> which allows you to add items dynamically.

If this is not an option, you can use Array.Copy or Array.CopyTo to copy the array into a larger array.

You need to #include <cstdint>, but that may not always work.

The problem is that some compiler often automatically export names defined in various headers or provided types before such standards were in place.

Now, I said "may not always work." That's because the cstdint header is part of the C++11 standard and is not always available on current C++ compilers (but often is). The stdint.h header is the C equivalent and is part of C99.

For best portability, I'd recommend using Boost's boost/cstdint.hpp header, if you're willing to use boost. Otherwise, you'll probably be able to get away with #include'ing <cstdint>.

You can see value inside [object Object] like this

Alert.alert(  JSON.stringify(userDate)  );

Try like this

    realm.write(() => {
       const userFormData = realm.create('User',{
       user_email: value.username,
       user_password: value.password,
      });
     });

      const userDate = realm.objects('User').filtered('user_email == $0', value.username.toString(), );
      Alert.alert(  JSON.stringify(userDate)  );

The files/folder in your version control will not just delete themselves just because you added them to the .gitignore. They are already in the repository and you have to remove them. You can just do that with this:

Remember to commit everything you've changed before you do this!

git rm -rf --cached .
git add .

This removes all files from the repository and adds them back (this time respecting the rules in your .gitignore).

You can override the default css rules with this:

.table tbody tr > td.success {
  background-color: #dff0d8 !important;
}

.table tbody tr > td.error {
  background-color: #f2dede !important;
}

.table tbody tr > td.warning {
  background-color: #fcf8e3 !important;
}

.table tbody tr > td.info {
  background-color: #d9edf7 !important;
}

.table-hover tbody tr:hover > td.success {
  background-color: #d0e9c6 !important;
}

.table-hover tbody tr:hover > td.error {
  background-color: #ebcccc !important;
}

.table-hover tbody tr:hover > td.warning {
  background-color: #faf2cc !important;
}

.table-hover tbody tr:hover > td.info {
  background-color: #c4e3f3 !important;
}

!important is needed as bootstrap actually colours the cells individually (afaik it's not possible to just apply background-color to a tr). I couldn't find any colour variables in my version of bootstrap but that's the basic idea anyway.

I'll start off my noting that this hasn't happened since I upgraded my RAM. I was at 4GB and would often have multiple instances of VS open along with SSMS. I have since gone to 8GB and then 16GB.

Here's the steps I go through when I lose intellisense.

If only one file/window appears to be affected, close/reopen that file. If that doesn't work, try below.

In Visual Studio:

1. Click Tools->Options->Text Editor->All Languages->General
2. Uncheck "Auto list members"
3. Uncheck "Parameter information"
4. Check "Auto list members" (yes, the one you just unchecked)
5. Check "Parameter information" (again, the one you just unchecked)
6. Click OK

If this doesn't work, here's a few more steps to try:

1. Close all VS documents and reopen
2. If still not working, close/reopen solution
3. If still not working, restart VS.

For C++ projects:
MSDN has a few things to try: MSDN suggestions

The corrupt .ncb file seems most likely.

From MSDN:

1. Close the solution.
2. Delete the .ncb file.
3. Reopen the solution. (This creates a new .ncb file.)

Notes:

• This issue does not appear to be specific to C# as C++ and VB users report the same issue

• Tested in VS 2013/2015

.prop('disabled') will return a Boolean:

var isDisabled = $('textbox').prop('disabled');

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

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

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

More info:

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

If you already committed the changes than you would have to revert changes.

If you didn't commit yet, just do a clean checkout git checkout .

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

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

Using just simple loops:

public static void compareSortOrder (List<String> sortOrder, List<String> listToCompare){
        int currentSortingLevel = 0;
        for (int i=0; i<listToCompare.size(); i++){
            System.out.println("Item from list: " + listToCompare.get(i));
            System.out.println("Sorting level: " + sortOrder.get(currentSortingLevel));
            if (listToCompare.get(i).equals(sortOrder.get(currentSortingLevel))){

            } else {
                try{
                    while (!listToCompare.get(i).equals(sortOrder.get(currentSortingLevel)))
                        currentSortingLevel++;
                    System.out.println("Changing sorting level to next value: " + sortOrder.get(currentSortingLevel));
                } catch (ArrayIndexOutOfBoundsException e){

                }

            }
        }
    }

And sort order in List

public static List<String> ALARMS_LIST = Arrays.asList(
            "CRITICAL",
            "MAJOR",
            "MINOR",
            "WARNING",
            "GOOD",
            "N/A");

//I think this way we could go :
int my_atoi(const char* snum)
{
 int nInt(0);
 int index(0);
 while(snum[index])
 {
    if(!nInt)
        nInt= ( (int) snum[index]) - 48;
    else
    {
        nInt = (nInt *= 10) + ((int) snum[index] - 48);
    }
    index++;
 }
 return(nInt);
}

int main()
{
    printf("Returned number is: %d\n", my_atoi("676987"));
    return 0;
}

• Edit ---> Project Settings ---> Time ... decrease "Fixed Timestep" value .. This will solve the problem but it can affect performance negatively.

• Another solution is could be calculate the coordinates (for example, you have a ball and wall. Ball will hit to wall. So calculate coordinates of wall and set hitting process according these cordinates )

From Oracle (but works in most SQL DBs):

SELECT LASTNAME, COUNT(*)
FROM STUDENTS
GROUP BY LASTNAME
HAVING COUNT(*) >= 3

P.S. it's faster one, because you have no Select withing Select methods here

For Angular9+, according to this, you can use:

.mat-select-panel {
    background: red;
    ....
}

Demo

1. Use ::ng-deep:

Use the /deep/ shadow-piercing descendant combinator to force a style down through the child component tree into all the child component views. The /deep/ combinator works to any depth of nested components, and it applies to both the view children and content children of the component. Use /deep/, >>> and ::ng-deep only with emulated view encapsulation. Emulated is the default and most commonly used view encapsulation. For more information, see the Controlling view encapsulation section. The shadow-piercing descendant combinator is deprecated and support is being removed from major browsers and tools. As such we plan to drop support in Angular (for all 3 of /deep/, >>> and ::ng-deep). Until then ::ng-deep should be preferred for a broader compatibility with the tools.

CSS:

::ng-deep .mat-select-content{
    width:2000px;
    background-color: red;
    font-size: 10px;   
}

DEMO

2. Use ViewEncapsulation

... component CSS styles are encapsulated into the component's view and don't affect the rest of the application. To control how this encapsulation happens on a per component basis, you can set the view encapsulation mode in the component metadata. Choose from the following modes: .... None means that Angular does no view encapsulation. Angular adds the CSS to the global styles. The scoping rules, isolations, and protections discussed earlier don't apply. This is essentially the same as pasting the component's styles into the HTML.

None value is what you will need to break the encapsulation and set material style from your component. So can set on the component's selector:

Typscript:

  import {ViewEncapsulation } from '@angular/core';
  ....
  @Component({
        ....
        encapsulation: ViewEncapsulation.None
 })  

CSS

.mat-select-content{
    width:2000px;
    background-color: red;
    font-size: 10px;
}

DEMO

3. Set class style in style.css

This time you have to 'force' styles with !important too.

style.css

 .mat-select-content{
   width:2000px !important;
   background-color: red !important;
   font-size: 10px !important;
 } 

DEMO

4. Use inline style

<mat-option style="width:2000px; background-color: red; font-size: 10px;" ...>

DEMO

Here is the same function@Triptych provided as a generator, which has also been simplified slightly.

def primes(n):
    d = 2
    while (n > 1):
        while (n%d==0):
            yield d
            n /= d
        d += 1

the max prime can then be found using:

n= 373764623
max(primes(n))

and a list of factors found using:

list(primes(n))

just install rxjs-compat by typing in terminal:

To ADD classes to html elements see how to add css class to html generic control div?. There are answers similar to those given here but showing how to add classes to html elements.

If the recommended answer didn't help because you are already using a newer version of bundler. Try the solution that worked for me.

Delete everything inside your vendor folder. Add a line to your gemfile

gem 'json', '1.8.0'

Then run - bundle update json.

It seems to be an issue with 1.8.1 so going back to 1.8.0 did the trick for me.

In my case, I was executing Maven Build from Eclipse Run Configurations. Even after changing the default JRE configuration to point to JDK installation folder, the issue didn't get fixed for me. The reason is that there is a JRE tab in the Maven Build - Run Configuration (see the image below). And it was still pointing to my JRE installation. I changed it to point to JDK installation and then ran the Maven Build. This time, it worked. enter image description here

Recommended is to use JSON.parse

There is an alternative you can do :

 var myObject = eval('(' + myJSONtext + ')');

Json in javascript

Why is using the JavaScript eval function a bad idea?

The PowerCollections library (formerly available from Wintellect but now hosted on Codeplex @ http://powercollections.codeplex.com) has a generic Pair structure.

You can do it like this, and no need to dedicate variable:

Toolbar toolbar = findViewById(R.id.toolbar);
Menu menu = toolbar.getMenu();
MenuItem menuItem = menu.findItem(R.id.some_action);
menuItem.setTitle("New title");

Or a little simplified:

MenuItem menuItem = ((Toolbar)findViewById(R.id.toolbar)).getMenu().findItem(R.id.some_action);
menuItem.setTitle("New title");

It works only - after the menu created.

You can use DataTable.Select:

var strExpr = "CostumerID = 1 AND OrderCount > 2";
var strSort = "OrderCount DESC";

// Use the Select method to find all rows matching the filter.
foundRows = ds.Table[0].Select(strExpr, strSort);  

Or you can use DataView:

ds.Tables[0].DefaultView.RowFilter = strExpr;  

UPDATE I'm not sure why you want to have a DataSet returned. But I'd go with the following solution:

var dv = ds.Tables[0].DefaultView;
dv.RowFilter = strExpr;
var newDS = new DataSet();
var newDT = dv.ToTable();
newDS.Tables.Add(newDT);

The documentation for focusout says (emphasis mine):

The focusout event is sent to an element when it, or any element inside of it, loses focus. This is distinct from the blur event in that it supports detecting the loss of focus on descendant elements (in other words, it supports event bubbling).

The same distinction exists between the focusin and focus events.

From Prepared statements and stored procedures

Use bindParam to insert multiple rows with one time binding:

<?php

$stmt = $dbh->prepare("INSERT INTO REGISTRY (name, value) VALUES (?, ?)");
$stmt->bindParam(1, $name);
$stmt->bindParam(2, $value);

// insert one row
$name = 'one';
$value = 1;
$stmt->execute();

// insert another row with different values
$name = 'two';
$value = 2;
$stmt->execute();

For example,

package main

import "fmt"

func main() {
    type Map1 map[string]interface{}
    type Map2 map[string]int
    m := Map1{"foo": Map2{"first": 1}, "boo": Map2{"second": 2}}
    //m = map[foo:map[first: 1] boo: map[second: 2]]
    fmt.Println("m:", m)
    for k, v := range m {
        fmt.Println("k:", k, "v:", v)
    }
}

Output:

m: map[boo:map[second:2] foo:map[first:1]]
k: boo v: map[second:2]
k: foo v: map[first:1]

you can use

<meta http-equiv="refresh" content="10" > 

just add it after the head tags

where 10 is the time your page will refresh itself

Open Sql server 2014 Configuration Manager.

Click Sql server services and start the sql server service if it is stopped

Then click Check SQL server Network Configuration for TCP/IP Enabled

then restart the sql server management studio (SSMS) and connect your local database engine

Javascript variables can have letters, digits, dollar signs ($) and underscores (_). They can't start with digits.

Usually libraries use $ and _ as shortcuts for functions that you'll be using everywhere. Although the names $ or _ aren't meaningful, they're useful for their shortness and since you'll be using the function everywhere you're expected to know what they mean.

If your library doesn't consist on getting a single function being used everywhere, I'd recommend that you use more meaningful names as those will help you and others understand what your code is doing without necessarily compromising the source code niceness.

You could for instance take a look at the awesome DateJS library and at the syntatic sugar it allows without the need of any symbol or short-named variables.

You should first get your code to be practical, and only after try making it pretty.

You can do this with CSS Variable

.box-shadow {
    --box-shadow-color: #000; /* Declaring the variable */
    width: 30px;                
    height: 30px;
    box-shadow: 1px 1px 25px var(--box-shadow-color); /* Calling the variable */

}

.box-shadow:hover  {
    --box-shadow-color: #ff0000; /* Changing the value of the variable */
}

Demo

My first post...

I tried this: change 'tr' for 'td' and you will get all HTMLRowElements into an Array, and using textContent will change from Object into String

var dataArray = [];
var data = table.find('td'); //Get All HTML td elements

// Save important data into new Array
for (var i = 0; i <= data.size() - 1; i = i + 4)
{
  dataArray.push(data[i].textContent, data[i + 1].textContent, data[i + 2].textContent);
}

The solution I end up using most is based off of Tomas Petricek's answer. I usually want to do something with both the attribute and property.

var props = from p in this.GetType().GetProperties()
            let attr = p.GetCustomAttributes(typeof(MyAttribute), true)
            where attr.Length == 1
            select new { Property = p, Attribute = attr.First() as MyAttribute};

You can customize material styles by setting different color properties. For example custom application theme

<style name="CustomAppTheme" parent="Theme.AppCompat">
    <item name="android:textColorPrimaryDisableOnly">#00838f</item>
    <item name="colorAccent">#e91e63</item>
</style>

Custom switch theme

<style name="MySwitch" parent="@style/Widget.AppCompat.CompoundButton.Switch">
    <item name="android:textColorPrimaryDisableOnly">#b71c1c</item>
    <item name="android:colorControlActivated">#1b5e20</item>
    <item name="android:colorForeground">#f57f17</item>
    <item name="android:textAppearance">@style/TextAppearance.AppCompat</item>
</style>

You can customize switch track and switch thumb like below image by defining xml drawables. For more information http://www.zoftino.com/android-switch-button-and-custom-switch-examples

An answer I read on another thread similar to this one that worked for me when I had this problem involved the layout xml.

Your logcat says "No view found for id 0x7f080011".

Open up the gen->package->R.java->id and then look for id 0x7f080011.

When I had this problem, this id belonged to a FrameLayout in my activity_main.xml file.

The FrameLayout did not have an ID (there was no statement android:id = "blablabla").

Make sure that all of your components in all of your layouts have IDs, particularly the component cited in the logcat.

Follow following steps:

1. Copy hello.ko to /lib/modules/'uname-r'/misc/
2. Add misc/hello.ko entry in /lib/modules/'uname-r'/modules.dep
3. sudo depmod
4. sudo modprobe hello

modprobe will check modules.dep file for any dependency.

If you are using AdonisJS and have mixed IDs such as ABC-202, ABC-201..., you can combine raw queries with Query Builder and implement the solution above (https://stackoverflow.com/a/25061144/4040835) as follows:

const sortField =
  'membership_id'
const sortDirection =
  'asc'
const subquery = UserProfile.query()
  .select(
    'user_profiles.id',
    'user_profiles.user_id',
    'user_profiles.membership_id',
    'user_profiles.first_name',
    'user_profiles.middle_name',
    'user_profiles.last_name',
    'user_profiles.mobile_number',
    'countries.citizenship',
    'states.name as state_of_origin',
    'user_profiles.gender',
    'user_profiles.created_at',
    'user_profiles.updated_at'
  )
  .leftJoin(
    'users',
    'user_profiles.user_id',
    'users.id'
  )
  .leftJoin(
    'countries',
    'user_profiles.nationality',
    'countries.id'
  )
  .leftJoin(
    'states',
    'user_profiles.state_of_origin',
    'states.id'
  )
  .orderByRaw(
    `SUBSTRING(:sortField:,3,15)*1 ${sortDirection}`,
    {
      sortField: sortField,
    }
  )
  .paginate(
    page,
    per_page
  )

NOTES: In this line: SUBSTRING(:sortField:,3,15)*1 ${sortDirection},

1. '3' stands for the index number of the last non-numerical character before the digits. If your mixed ID is "ABC-123," your index number will be 4.
2. '15' is used to catch as any number of digits as possible after the hyphen.
3. '1' performs a mathematical operation on the substring which effectively casts the substring to a number.

As Bakkal explained, for the keyboard shortcuts, in netbeans you can go to tools->options->editor->code templates and add or edit your own shortcuts.

In Eclipse it's on templates.

There are good answers here but If you like to have some interface for postgres database management, you can install pgAdmin on your local computer and connect to the remote machine using its IP and the postgres exposed port (by default 5432).

Here is another way to change timezone in datetime format (I know I wasted my energy on this but I didn't see this page so I don't know how) without min. and sec. cause I don't need it for my project:

def change_time_zone(year, month, day, hour):
      hour = hour + 7 #<-- difference
      if hour >= 24:
        difference = hour - 24
        hour = difference
        day += 1
        long_months = [1, 3, 5, 7, 8, 10, 12]
        short_months = [4, 6, 9, 11]
        if month in short_months:
          if day >= 30:
            day = 1
            month += 1
            if month > 12:
              year += 1
        elif month in long_months:
          if day >= 31:
            day = 1
            month += 1
            if month > 12:
              year += 1
        elif month == 2:
          if not year%4==0:
            if day >= 29:
              day = 1
              month += 1
              if month > 12:
                year += 1
          else:
            if day >= 28:
              day = 1
              month += 1
              if month > 12:
                year += 1
      return datetime(int(year), int(month), int(day), int(hour), 00)

View>Tool Windows>Run

It will show you the console

I also had the same problem. I used next way:

1.Added settings.xml file (~/.m2/settings.xml) with next content

<proxies>
   <proxy>
      <active>true</active>
      <protocol>http</protocol>
      <host>qq-proxya</host>
      <port>8080</port>
      <username>user</username>
      <password>passw</password>
      <nonProxyHosts>www.google.com|*.example.com</nonProxyHosts>
    </proxy>
  </proxies>

3. Using cmd go to folder with my project and wrote mvn clean and after that mvn install !

4. After that updated project in the Eclipse(Alt + F5) or right click on project -> Maven -> Update project

P.S. after that, when I add new dependency to my project I have to compile project using cmd(mvn compile). Because if I do it using eclipse plugin, I get error connecting with proxy connection.

public class SwitchTest {
    public static void main(String[] args){
        for(int i = 0;i<10;i++){
            switch(i){
                case 1: case 2: case 3: case 4: //First case
                    System.out.println("First case");
                    break;
                case 8: case 9: //Second case
                    System.out.println("Second case");
                    break;
                default: //Default case
                    System.out.println("Default case");
                    break;
            }
        }
    }
}

Out:

Default case
First case
First case
First case
First case
Default case
Default case
Default case
Second case

PROBLEM

• PHP function simplexml_load_file is throwing parsing error parser error : xmlParseEntityRef while trying to load the XML file from a URL.

CAUSE

• XML returned by the URL is not a valid XML. It contains & value instead of &. It is quite possible that there are other errors which aren't obvious at this point of time.

THINGS OUT OF OUR CONTROL

• Ideally, we should make sure that a valid XML is feed into PHP simplexml_load_file function, but it looks like we don't have any control over how the XML is created.
• It is also not possible to force simplexml_load_file to process an invalid XML file. It does not leave us with many options, other than fixing the XML file itself.

POSSIBLE SOLUTION

Convert Invalid XML to Valid XML. It can be done using PHP tidy extension. Further instructions can be found from http://php.net/manual/en/book.tidy.php

Once you are sure that the extension exists or is installed, please do the following.

/**
 * As per the question asked, the URL is loaded into a variable first, 
 * which we can assume to be $xml
 */
$xml = <<<XML
<?xml version="1.0" encoding="UTF-8"?>
<project orderno="6" campaign_name="International Relief & Development for under developed nations">
    <invalid-data>Some other data containing & in it</invalid-data>
    <unclosed-tag>
</project>
XML;

/**
 * Whenever we use tidy it is best to pass some configuration options 
 * similar to $tidyConfig. In this particular case we are making sure that
 * tidy understands that our input and output is XML.
 */
$tidyConfig = array (
    'indent' => true,
    'input-xml' => true, 
    'output-xml' => true,
    'wrap' => 200
);

/**
 * Now we can use tidy to parse the string and then repair it.
 */
$tidy = new tidy;
$tidy->parseString($xml, $tidyConfig, 'utf8');
$tidy->cleanRepair();

/**
 * If we try to output the repaired XML string by echoing $tidy it should look like. 

 <?xml version="1.0" encoding="utf-8"?>
 <project orderno="6" campaign_name="International Relief &amp; Development for under developed nations">
      <invalid-data>Some other data containing &amp; in it</invalid-data>
      <unclosed-tag></unclosed-tag>
 </project> 

 * As you can see that & is now fixed in campaign_name attribute 
 * and also with-in invalid-data element. You can also see that the   
 * <unclosed-tag> which didn't had a close tag, has been fixed too.
 */
echo $tidy;

/**
 * Now when we try to use simplexml_load_string to load the clean XML. When we
 * try to print_r it should look something like below.

 SimpleXMLElement Object
(
    [@attributes] => Array
        (
            [orderno] => 6
            [campaign_name] => International Relief & Development for under developed nations
        )

    [invalid-data] => Some other data containing & in it
    [unclosed-tag] => SimpleXMLElement Object
        (
        )

)

 */
 $simpleXmlElement = simplexml_load_string($tidy);
 print_r($simpleXmlElement);

CAUTION

The developer should try to compare the invalid XML with a valid XML (generated by tidy), to see there are no adverse side effects after using tidy. Tidy does an extremely good job of doing it correctly, but it never hurts to see it visually and to be 100% sure. In our case it should be as simple as comparing $xml with $tidy.

You should use

$this->db->where('$accommodation >=', minvalue);
$this->db->where('$accommodation <=', maxvalue);

I'm not sure of syntax, so I beg your pardon if it's not correct.
Anyway BETWEEN is implemented using >=min && <=max.
This is the meaning of my example.

EDITED:
Looking at this link I think you could write:

$this->db->where("$accommodation BETWEEN $minvalue AND $maxvalue");

A horrendous example using regular expressions (you could easily clean this up :) ):

def f(s):
    return s.group(1).lower() + "_" + s.group(2).lower()

p = re.compile("([A-Z]+[a-z]+)([A-Z]?)")
print p.sub(f, "CamelCase")
print p.sub(f, "getHTTPResponseCode")

Works for getHTTPResponseCode though!

Alternatively, using lambda:

p = re.compile("([A-Z]+[a-z]+)([A-Z]?)")
print p.sub(lambda x: x.group(1).lower() + "_" + x.group(2).lower(), "CamelCase")
print p.sub(lambda x: x.group(1).lower() + "_" + x.group(2).lower(), "getHTTPResponseCode")

EDIT: It should also be pretty easy to see that there's room for improvement for cases like "Test", because the underscore is unconditionally inserted.

There is no linguistic support to do what you're asking for.

You can reflectively access the members of a type at run-time using reflection (e.g. with Class.getDeclaredFields() to get an array of Field), but depending on what you're trying to do, this may not be the best solution.

• How could Reflection not lead to code smells?
• Dumping a java object’s properties

Example

Here's a simple example to show only some of what reflection is capable of doing.

import java.lang.reflect.*;

public class DumpFields {
    public static void main(String[] args) {
        inspect(String.class);
    }
    static <T> void inspect(Class<T> klazz) {
        Field[] fields = klazz.getDeclaredFields();
        System.out.printf("%d fields:%n", fields.length);
        for (Field field : fields) {
            System.out.printf("%s %s %s%n",
                Modifier.toString(field.getModifiers()),
                field.getType().getSimpleName(),
                field.getName()
            );
        }
    }
}

The above snippet uses reflection to inspect all the declared fields of class String; it produces the following output:

7 fields:
private final char[] value
private final int offset
private final int count
private int hash
private static final long serialVersionUID
private static final ObjectStreamField[] serialPersistentFields
public static final Comparator CASE_INSENSITIVE_ORDER

Effective Java 2nd Edition, Item 53: Prefer interfaces to reflection

These are excerpts from the book:

Given a Class object, you can obtain Constructor, Method, and Field instances representing the constructors, methods and fields of the class. [They] let you manipulate their underlying counterparts reflectively. This power, however, comes at a price:

• You lose all the benefits of compile-time checking.
• The code required to perform reflective access is clumsy and verbose.
• Performance suffers.

As a rule, objects should not be accessed reflectively in normal applications at runtime.

There are a few sophisticated applications that require reflection. Examples include [...omitted on purpose...] If you have any doubts as to whether your application falls into one of these categories, it probably doesn't.

Based on @Eyal Ben Dov's answer you may want to create a category to make it flexible to use within another apps of yours.

Obs.: I've updated his code to make compatible with iOS 7

-Header file

#import <UIKit/UIKit.h>

@interface UILabel (DynamicFontSize)

-(void) adjustFontSizeToFillItsContents;

@end

-Implementation file

#import "UILabel+DynamicFontSize.h"

@implementation UILabel (DynamicFontSize)

#define CATEGORY_DYNAMIC_FONT_SIZE_MAXIMUM_VALUE 35
#define CATEGORY_DYNAMIC_FONT_SIZE_MINIMUM_VALUE 3

-(void) adjustFontSizeToFillItsContents
{
    NSString* text = self.text;

    for (int i = CATEGORY_DYNAMIC_FONT_SIZE_MAXIMUM_VALUE; i>CATEGORY_DYNAMIC_FONT_SIZE_MINIMUM_VALUE; i--) {

        UIFont *font = [UIFont fontWithName:self.font.fontName size:(CGFloat)i];
        NSAttributedString *attributedText = [[NSAttributedString alloc] initWithString:text attributes:@{NSFontAttributeName: font}];

        CGRect rectSize = [attributedText boundingRectWithSize:CGSizeMake(self.frame.size.width, CGFLOAT_MAX) options:NSStringDrawingUsesLineFragmentOrigin context:nil];

        if (rectSize.size.height <= self.frame.size.height) {
            self.font = [UIFont fontWithName:self.font.fontName size:(CGFloat)i];
            break;
        }
    }

}

@end

-Usage

#import "UILabel+DynamicFontSize.h"

[myUILabel adjustFontSizeToFillItsContents];

Try using an X-Y Scatter graph with datetime formatted as YYYY-MM-DD HH:MM.

This provides a reasonable graph for me (using Excel 2010).

take a look at this code

<form action="result.php" method="post">
Answer 1 <input type="radio" name="ans" value="ans1" /><br />
Answer 2 <input type="radio" name="ans" value="ans2"  /><br />
Answer 3 <input type="radio" name="ans" value="ans3"  /><br />
Answer 4 <input type="radio" name="ans" value="ans4"  /><br />
<input type="submit" value="submit" />
</form>

php

<?php 
if(isset($_POST['submit'])){
if(isset( $_POST['ans'])){  
echo "This is the value you are selected".$_POST['ans'];          
}         
}
?>

Just in case anyone runs into my issue and has no luck with the other solutions... I was trying to start an activity through adb for FireTV while debugging Amazon launcher integration. However, my project had 60 different build variants (multi-platform, multi-app project) and the ApplicationId didn't match any classpath since the runtime package (and classpaths) were different from the applicationId.

I was trying to run adb shell am start -n com.myappid.example.packageone.packagetwo/com.myappid.example.packageone.packagetwo.MySplashActivity

(Of course I had tried many combinations with com.runtimepath.example since I had the added challenge of a different applicationId in my build.gradle and another at runtime)

What finally helped was this post https://stackoverflow.com/a/36255727/5970652

Which revealed a different format! com.myappid.example/com.runtimepath.example.packageone.packagetwo.MySplashActivity

So if you have a different runtime classpath try specifying with the build.gradle applicationId before the slash and the runtime classpath afterwards.

You can also get these values from BuildConfig.APPLICATION_ID and this.getLocalClassName() respectively if you want to log them in logcat.

If trigger("chosen:updated"); not working, use .trigger("liszt:updated"); of @Nhan Tran it is working fine.

Your mistake is looking for range, which gives you the range of a vector, for example:

range(c(10, -5, 100))

gives

 -5 100

Instead, look at the : operator to give sequences (with a step size of one):

1:100

or you can use the seq function to have a bit more control. For example,

##Step size of 2
seq(1, 100, by=2)

or

##length.out: desired length of the sequence
seq(1, 100, length.out=5)

Building on @IllidanS4 's answer, I have created a template class that allows virtually any member function with predefined arguments and class instance to be passed by reference for later calling.

template<class RET, class... RArgs> class Callback_t {
public:
    virtual RET call(RArgs&&... rargs) = 0;
    //virtual RET call() = 0;
};

template<class T, class RET, class... RArgs> class CallbackCalltimeArgs : public Callback_t<RET, RArgs...> {
public:
    T * owner;
    RET(T::*x)(RArgs...);
    RET call(RArgs&&... rargs) {
        return (*owner.*(x))(std::forward<RArgs>(rargs)...);
    };
    CallbackCalltimeArgs(T* t, RET(T::*x)(RArgs...)) : owner(t), x(x) {}
};

template<class T, class RET, class... Args> class CallbackCreattimeArgs : public Callback_t<RET> {
public:
    T* owner;
    RET(T::*x)(Args...);
    RET call() {
        return (*owner.*(x))(std::get<Args&&>(args)...);
    };
    std::tuple<Args&&...> args;
    CallbackCreattimeArgs(T* t, RET(T::*x)(Args...), Args&&... args) : owner(t), x(x),
        args(std::tuple<Args&&...>(std::forward<Args>(args)...)) {}
};

Test / example:

class container {
public:
    static void printFrom(container* c) { c->print(); };
    container(int data) : data(data) {};
    ~container() {};
    void print() { printf("%d\n", data); };
    void printTo(FILE* f) { fprintf(f, "%d\n", data); };
    void printWith(int arg) { printf("%d:%d\n", data, arg); };
private:
    int data;
};

int main() {
    container c1(1), c2(20);
    CallbackCreattimeArgs<container, void> f1(&c1, &container::print);
    Callback_t<void>* fp1 = &f1;
    fp1->call();//1
    CallbackCreattimeArgs<container, void, FILE*> f2(&c2, &container::printTo, stdout);
    Callback_t<void>* fp2 = &f2;
    fp2->call();//20
    CallbackCalltimeArgs<container, void, int> f3(&c2, &container::printWith);
    Callback_t<void, int>* fp3 = &f3;
    fp3->call(15);//20:15
}

Obviously, this will only work if the given arguments and owner class are still valid. As far as readability... please forgive me.

Edit: removed unnecessary malloc by making the tuple normal storage. Added inherited type for the reference. Added option to provide all arguments at calltime instead. Now working on having both....

Edit 2: As promised, both. Only restriction (that I see) is that the predefined arguments must come before the runtime supplied arguments in the callback function. Thanks to @Chipster for some help with gcc compliance. This works on gcc on ubuntu and visual studio on windows.

Here are some examples which assume $element is a jQuery element:

// Element width including overflow (scrollbar)
$element[0].offsetWidth; // 1280 in your case

// Element width excluding overflow (scrollbar)
$element[0].clientWidth; // 1280 - scrollbarWidth

// Scrollbar width
$element[0].offsetWidth - $element[0].clientWidth; // 0 if no scrollbar

As a one-liner:

var result = Regex.Replace(input, @"[^\x00-\x7F]", c => 
    string.Format(@"\u{0:x4}", (int)c.Value[0]));

Java supports shallow(not deep) copy concept

You can archive it using:

• constructor
• clone()
• putAll()

add the onclick attribute

<div onclick="myFunction( event );"><span>shanghai</span><span>male</span></div>

To get the cursor to change use css's cursor rule.

div[onclick] {
  cursor: pointer;
}

The selector uses an attribute selector which does not work in some versions of IE. If you want to support those versions, add a class to your div.

It looks like a common gaps-and-islands problem. The difference between two sequences of row numbers rn1 and rn2 give the "group" number.

Run this query CTE-by-CTE and examine intermediate results to see how it works.

Sample data

I expanded sample data from the question a little.

DECLARE @Source TABLE
(
    EmployeeID int,
    DateStarted date,
    DepartmentID int
)

INSERT INTO @Source
VALUES
(10001,'2013-01-01',001),
(10001,'2013-09-09',001),
(10001,'2013-12-01',002),

Query for SQL Server 2008

There is no LEAD function in SQL Server 2008, so I had to use self-join via OUTER APPLY to get the value of the "next" row for the DateEnd.

WITH
CTE
AS
(
    SELECT
        EmployeeID
        ,DateStarted
        ,DepartmentID
        ,ROW_NUMBER() OVER (PARTITION BY EmployeeID ORDER BY DateStarted) AS rn1
        ,ROW_NUMBER() OVER (PARTITION BY EmployeeID, DepartmentID ORDER BY DateStarted) AS rn2
    FROM @Source
)
,CTE_Groups
AS
(
    SELECT
        EmployeeID
        ,MIN(DateStarted) AS DateStart
        ,DepartmentID
    FROM CTE
    GROUP BY
        EmployeeID
        ,DepartmentID
        ,rn1 - rn2
)
SELECT
    CTE_Groups.EmployeeID
    ,CTE_Groups.DepartmentID
    ,CTE_Groups.DateStart
    ,A.DateEnd
FROM
    CTE_Groups
    OUTER APPLY
    (
        SELECT TOP(1) G2.DateStart AS DateEnd
        FROM CTE_Groups AS G2
        WHERE
            G2.EmployeeID = CTE_Groups.EmployeeID
            AND G2.DateStart > CTE_Groups.DateStart
        ORDER BY G2.DateStart
    ) AS A
ORDER BY
    EmployeeID
    ,DateStart
;

Query for SQL Server 2012+

Starting with SQL Server 2012 there is a LEAD function that makes this task more efficient.

WITH
CTE
AS
(
    SELECT
        EmployeeID
        ,DateStarted
        ,DepartmentID
        ,ROW_NUMBER() OVER (PARTITION BY EmployeeID ORDER BY DateStarted) AS rn1
        ,ROW_NUMBER() OVER (PARTITION BY EmployeeID, DepartmentID ORDER BY DateStarted) AS rn2
    FROM @Source

    SELECT
        EmployeeID
        ,MIN(DateStarted) AS DateStart
        ,DepartmentID
    FROM CTE
    GROUP BY
        EmployeeID

//list_tables means database all table

$tables = $this->db->list_tables();
foreach ($tables as $table)
{
  echo $table;
}

It might be easier to use JavaScript or jquery for this. Assuming that the height of the header and the footer is 200 then the code will be:

function SetHeight(){
    var h = $(window).height();
    $("#inner-right").height(h-200);    
}

$(document).ready(SetHeight);
$(window).resize(SetHeight);

You have to find the right user that needs to use temp folder. In my computer I follow the above link and find the special folder c:\inetpub, that iis use to execute her web services. I check what users could use these folder and find something like these: computername\iis_isusrs

The main issue comes when you try to add it to all permit on temp folder I was going to properties, security tab, edit button, add user button then i put iis_isusrs

and "check names" button

It doesn´t find anything The reason is the in my case it looks ( windows 2008 r2 iis 7 ) on pdgs.local location You have to go to "Select Users or Groups" form, click on Advanced button, click on Locations button and will see a specific hierarchy

• computername
• Entire Directory
• • pdgs.local

So when you try to add an user, its search name on pdgs.local. You have to select computername and click ok, Click on "Find Now"

Look for IIS_IUSRS on Name(RDN) column, click ok. So we go back to "Select Users or Groups" form with new and right user underline

click ok, allow full control, and click ok again.

That´s all folks, Hope it helps,

padding-right works for me in Firefox/Chrome on Windows but not in IE. Welcome to the wonderful world of IE standards non-compliance.

See: http://jsfiddle.net/SfPju/466/

HTML

<input type="text" class="foo" value="abcdefghijklmnopqrstuvwxyz"/>

CSS

.foo
{
    padding-right: 20px;
}

Your Fragment can subclass ListFragment.
And onCreateView() from ListFragment will return a ListView you can then populate.

I've used jQuery MultiSelect for implementing multiselect drop down menu with checkbox. You can see the implementation guide from here - Multi-select Dropdown List with Checkbox

Implementation is very simple, need only using the following code.

$('#transactionType').multiselect({
    columns: 1,
    placeholder: 'Select Transaction Type'
});

Try this: https://docs.oracle.com/javase/1.5.0/docs/api/java/lang/String.html#replace%28java.lang.CharSequence,%20java.lang.CharSequence%29

String a = "HelloBrother How are you!";
String r = a.replace("HelloBrother","Brother");

System.out.println(r);

This would print out "Brother How are you!"

In Kotlin you must use MutableList or ArrayList.

Let's see how the methods of MutableList work:

var listNumbers: MutableList<Int> = mutableListOf(10, 15, 20)
// Result: 10, 15, 20

listNumbers.add(1000)
// Result: 10, 15, 20, 1000

listNumbers.add(1, 250)
// Result: 10, 250, 15, 20, 1000

listNumbers.removeAt(0)
// Result: 250, 15, 20, 1000

listNumbers.remove(20)
// Result: 250, 15, 1000

for (i in listNumbers) { 
    println(i) 
}

Let's see how the methods of ArrayList work:

var arrayNumbers: ArrayList<Int> = arrayListOf(1, 2, 3, 4, 5)
// Result: 1, 2, 3, 4, 5

arrayNumbers.add(20)
// Result: 1, 2, 3, 4, 5, 20

arrayNumbers.remove(1)
// Result: 2, 3, 4, 5, 20

arrayNumbers.clear()
// Result: Empty

for (j in arrayNumbers) { 
    println(j) 
}

Here are a couple possible solutions...

I have not tried all of these myself yet, but I will be trying them all soon.

Note: I do not have any personal or financial connection to any of these tools.

1) VB Script to EXE Converter (NOT Compiler): (Free)
vbs2exe.com.

The exe produced appears to be a true EXE.

From their website:

VBS to EXE is a free online converter that doesn't only convert your vbs files into exe but it also:

1- Encrypt your vbs file source code using 128 bit key.
2- Allows you to call win32 API
3- If you have troubles with windows vista especially when UAC is enabled then you may give VBS to EXE a try.
4- No need for wscript.exe to run your vbs anymore.
5- Your script is never saved to the hard disk like some others converters. it is a TRUE exe not an extractor.

This solution should work even if wscript/cscript is not installed on the computer.

Basically, this creates a true .EXE file. Inside the created .EXE is an "engine" that replaces wscript/cscript, and an encrypted copy of your VB Script code. This replacement engine executes your code IN MEMORY without calling wscript/cscript to do it.

2) Compile and Convert VBS to EXE...:
ExeScript

The current version is 3.5.

This is NOT a Free solution. They have a 15 day trial. After that, you need to buy a license for a hefty $44.96 (Home License/noncommercial), or $89.95 (Business License/commercial usage).

It seems to work in a similar way to the previous solution.

According to a forum post there:
Post: "A Exe file still need Windows Scripting Host (WSH) ??"

WSH is not required if "Compile" option was used, since ExeScript
implements it's own scripting host. ...

3) Encrypt the script with Microsoft's ".vbs to .vbe" encryption tool.

Apparently, this does not work for Windows 7/8, and it is possible there are ways to "decrypt" the .vbe file. At the time of writing this, I could not find a working link to download this. If I find one, I will add it to this answer.

    Interaction.MsgBox("Total Physical Memory" + Convert.ToInt32((My.Computer.Info.TotalPhysicalMemory) / (1024 * 1024)).ToString() + "Mb");
}

From the Visual C++ help, I'd tend to go with

/* ACCESS.C: This example uses _access to check the
 * file named "ACCESS.C" to see if it exists and if
 * writing is allowed.
 */

#include  <io.h>
#include  <stdio.h>
#include  <stdlib.h>

void main( void )
{
   /* Check for existence */
   if( (_access( "ACCESS.C", 0 )) != -1 )
   {
      printf( "File ACCESS.C exists\n" );
      /* Check for write permission */
      if( (_access( "ACCESS.C", 2 )) != -1 )
         printf( "File ACCESS.C has write permission\n" );
   }
}

Also worth noting mode values of _access(const char *path,int mode):

• 00: Existence only

• 02: Write permission

• 04: Read permission

• 06: Read and write permission

As your fopen could fail in situations where the file existed but could not be opened as requested.

Edit: Just read Mecki's post. stat() does look like a neater way to go. Ho hum.

Quickest (drops and creates all tables including data):

./manage.py reset appname | ./manage.py dbshell

Caution:

• Might not work on Windows correctly.
• Might keep some old tables in the db

Like this:

Dim rng as Range
Set rng = ActiveCell.Resize(numRows, numCols)

then read the contents of that range to an array:

Dim arr As Variant
arr = rng.Value
'arr is now a two-dimensional array of size (numRows, numCols)

or, select the range (I don't think that's what you really want, but you ask for this in the question).

rng.Select

Why not just use rm -rf __pycache__? Run git add -A afterwards to remove them from your repository and add __pycache__/ to your .gitignore file.

NOTE: For a concise and efficient solution, please see Marc-André Lafortune's answer below.

This answer was originally offered as an alternative to approaches using flatten, which were the most highly upvoted at the time of writing. I should have clarified that I didn't intend to present this example as a best practice or an efficient approach. Original answer follows.

Warning! Solutions using flatten will not preserve Array keys or values!

Building on @John Topley's popular answer, let's try:

a3 = [ ['apple', 1], ['banana', 2], [['orange','seedless'], 3] ]
h3 = Hash[*a3.flatten]

This throws an error:

ArgumentError: odd number of arguments for Hash
        from (irb):10:in `[]'
        from (irb):10

The constructor was expecting an Array of even length (e.g. ['k1','v1,'k2','v2']). What's worse is that a different Array which flattened to an even length would just silently give us a Hash with incorrect values.

If you want to use Array keys or values, you can use map:

h3 = Hash[a3.map {|key, value| [key, value]}]
puts "h3: #{h3.inspect}"

This preserves the Array key:

h3: {["orange", "seedless"]=>3, "apple"=>1, "banana"=>2}

var token = 'spo';

switch(token){
    case ( (token.match(/spo/) )? token : undefined ) :
       console.log('MATCHED')    
    break;;
    default:
       console.log('NO MATCH')
    break;;
}

--> If the match is made the ternary expression returns the original token
----> The original token is evaluated by case

--> If the match is not made the ternary returns undefined
----> Case evaluates the token against undefined which hopefully your token is not.

The ternary test can be anything for instance in your case

( !!~ base_url_string.indexOf('xxx.dev.yyy.com') )? xxx.dev.yyy.com : undefined 

===========================================

(token.match(/spo/) )? token : undefined ) 

is a ternary expression.

The test in this case is token.match(/spo/) which states the match the string held in token against the regex expression /spo/ ( which is the literal string spo in this case ).

If the expression and the string match it results in true and returns token ( which is the string the switch statement is operating on ).

Obviously token === token so the switch statement is matched and the case evaluated

It is easier to understand if you look at it in layers and understand that the turnery test is evaluated "BEFORE" the switch statement so that the switch statement only sees the results of the test.

You can use .length with just a descendant selector, like this:

var count = $("#selected li").length;

If you have to use .children(), then it's like this:

var count = $("#selected ul").children().length;

You can test both versions here.

You are incorrectly using Dependency Injection. The proper way is to have your controllers take the dependencies they need and leave to the dependency injection framework inject the concrete instances:

public class HomeController: Controller
{
    private readonly ISettingsManager settingsManager;
    public HomeController(ISettingsManager settingsManager)
    {
        this.settingsManager = settingsManager;
    }

    public ActionResult Index()
    {
        // you could use the this.settingsManager here
    }
}

As you can see in this example the controller doesn't know anything about the container. And that's how it should be.

All the DI wiring should happen in your Bootstraper. You should never use container.Resolve<> calls in your code.

As far as your error is concerned, probably the mUnityContainer you are using inside your controller is not the same instance as the one constructed in your Bootstraper. But since you shouldn't be using any container code in your controllers, this shouldn't be a problem anymore.

for my use case, i wanted to grab the SHA1 hash from the magisk config file. the below worked for me.

adb shell "su -c "cat /sbin/.magisk/config | grep SHA | awk -F= '{ print $2 }'""

Another way to get this error is to build using ant on macOS and have a Finder icon file (Icon\r) in the source tree of the app. It appears jarsigner can't cope with the carriage return in the filename and, although it will claim the signing is valid if you -verify the APK, it always results in an APK that wont install on a device. Ironically, the Google Drive Finder plugin is a great source of Finder icon files.

The solution is to exclude the offending files (which are useless in the APK anyway) with a specifier like this in the fileset:

    <exclude name="**/Icon&#13;" />

Suppose for example your date is coming like this & you need to install momentjs for advance date features.

let cmpDate = Thu Aug 27 2020 00:00:00 GMT+0530 (India Standard Time)

    let format = "MM/DD/YYYY";
    let startDate: any = moment().format(format);
    let endDate: any = moment().add(30, "days").format(format);
    let compareDate: any = moment(cmpDate).format(format);
    var startDate1 = startDate.split("/");
    var startDate2 = endDate.split("/");
    var compareDate1 = compareDate.split("/");

    var fromDate = new Date(startDate1[2], parseInt(startDate1[1]) - 1, startDate1[0]);
    var toDate = new Date(startDate2[2], parseInt(startDate2[1]) - 1, startDate2[0]);
    var checkDate = new Date(compareDate1[2], parseInt(compareDate1[1]) - 1, compareDate1[0]);

    if (checkDate > fromDate && checkDate < toDate) {
      ... condition works between current date to next 30 days
    }

For AngularJs you have to use "angular-datatables.min.js" file for datatable settings. You will get this from http://l-lin.github.io/angular-datatables/#/welcome.

After that you can write code like below,

<script>
     var app = angular.module('AngularWayApp', ['datatables']);
</script>

<div ng-app="AngularWayApp" ng-controller="AngularWayCtrl">
  <table id="example" datatable="ng" class="table">

You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.

Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String

'Assign data to first item in array
compArray(1) = "asdf"

'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"

'Prints "ErrorState"
Debug.Print Computers("Computer Name")

Collections cannot be sorted so if you need to sort data you will probably want to use an array.

Here is a link to the outlook developer reference. http://msdn.microsoft.com/en-us/library/office/ff866465%28v=office.14%29.aspx

Another great site to help you get started is http://www.cpearson.com/Excel/Topic.aspx

Moving everything over to VBA from VB.Net is not going to be simple since not all the data types are the same and you do not have the .Net framework. If you get stuck just post the code you're stuck converting and you will surely get some help!

Edit:

Sub ArrayExample()
    Dim subject As String
    Dim TestArray() As String
    Dim counter As Long

    subject = "Example"
    counter = Len(subject)

    ReDim TestArray(1 To counter) As String

    For counter = 1 To Len(subject)
        TestArray(counter) = Right(Left(subject, counter), 1)
    Next
End Sub

Here's how I do it.

function validate(phone) {_x000D_
  const regex = /^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/;_x000D_
  console.log(regex.test(phone))_x000D_
}_x000D_
_x000D_
validate('1234567890')     // true_x000D_
validate(1234567890)       // true_x000D_
validate('(078)789-8908')  // true_x000D_
validate('123-345-3456')   // true

The equivalent is the ? operator:

var value: NSNumber? = myQuestionableObject?.importantMethod()

importantMethod will only be called if myQuestionableObject exists and implements it.

Many of you must be landing here to find a solution for opaque border instead of a transparent one. In that case you can use rgba, where a stands for alpha.

.your_class {
    height: 100px;
    width: 100px;
    margin: 100px;
    border: 10px solid rgba(255,255,255,.5);
}

Demo

Here, you can change the opacity of the border from 0-1

If you simply want a complete transparent border, the best thing to use is transparent, like border: 1px solid transparent;

Swift 4 and higher

For Swift 4 and higher that is a good way:

    let attributsBold = [NSAttributedString.Key.font : UIFont.systemFont(ofSize: 16, weight: .bold)]
    let attributsNormal = [NSAttributedString.Key.font : UIFont.systemFont(ofSize: 16, weight: .regular)]
    var attributedString = NSMutableAttributedString(string: "Hi ", attributes:attributsNormal)
    let boldStringPart = NSMutableAttributedString(string: "John", attributes:attributsBold)
    attributedString.append(boldStringPart)
  
    yourLabel.attributedText = attributedString

In the Label the Text looks like: "Hi John"

If you'r developing some .Net app (for ex. web app), you can make 1 line of error code (like invoke wrong function name) and reload your page, the .Net version will be show

We can add for all devices with platform specific size

Your entity may not listed in hibernate configuration file.

Here's a solution that doesn't use JS at all. It uses checkboxes instead.

You can hide the checkbox by adding this to your CSS:

.container input{
    display: none;
}

And then add some styling to make it look like a button.

Here's the source code that I modded.

If your method is void and you want to check for an exception, you could use expected: https://weblogs.java.net/blog/johnsmart/archive/2009/09/27/testing-exceptions-junit-47

To set fixed 2 digits after the decimal point use these first:

cout.setf(ios::fixed);
cout.setf(ios::showpoint);
cout.precision(2);

Then print your double values.

This is an example:

#include <iostream>
using std::cout;
using std::ios;
using std::endl;

int main(int argc, char *argv[]) {
    cout.setf(ios::fixed);
    cout.setf(ios::showpoint);
    cout.precision(2);
    double d = 10.90;
    cout << d << endl;
    return 0;
}

The other one doesn't work. According to the docs this is the way you should do it.

angular.module('plunker', ['ui.bootstrap']);
var ModalDemoCtrl = function ($scope, $modal) {

    var modalInstance = $modal.open({
      templateUrl: 'myModalContent.html',
      controller: ModalInstanceCtrl,
      resolve: {
        test: function () {
          return 'test variable';
        }
      }
    });
};

var ModalInstanceCtrl = function ($scope, $modalInstance, test) {

  $scope.test = test;
};

See plunkr

You can also mix raw SQL with ActiveRecord conditions, for example if you want to call a function in a condition:

my_instances = MyModel.where.not(attribute_a: nil) \
  .where('crc32(attribute_b) = ?', slot) \
  .select(:id)

Looks like IE8-IE7 can't understand multiple Google Web Font styles through the same file request using the link tags href.

These two links helped me figure this out:

• See this open Google issue, and look at the comments.
• Also see this StackOverlow Answer Google Web Fonts don't work in IE8

The only way I have gotten it to work in IE7-IE8 is to only have one Google Web Font request. And only have one font style in the href of the link tag:

So normally you would have this, declaring multiple font styles in the same request:

<link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Open+Sans:400,600,300,800,700,400italic" /> 

But in IE7-IE8 add a IE conditional and specify each Google font style separately and it will work:

<!--[if lte IE 8]>
    <link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Open+Sans:400" /> 
    <link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Open+Sans:700" /> 
    <link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Open+Sans:800" />
<![endif]-->

Hope this can help others!

Assembly code is a human readable representation of machine code:

mov eax, 77
jmp anywhere

Machine code is pure hexadecimal code:

5F 3A E3 F1

I assume you mean object code as in an object file. This is a variant of machine code, with a difference that the jumps are sort of parameterized such that a linker can fill them in.

An assembler is used to convert assembly code into machine code (object code) A linker links several object (and library) files to generate an executable.

I have once written an assembler program in pure hex (no assembler available) luckily this was way back on the good old (ancient) 6502. But I'm glad there are assemblers for the pentium opcodes.

When indicating HTTP Basic Authentication we return something like:

WWW-Authenticate: Basic realm="myRealm"

Whereas Basic is the scheme and the remainder is very much dependent on that scheme. In this case realm just provides the browser a literal that can be displayed to the user when prompting for the user id and password.

You're obviously not using Basic however since there is no point having session expiry when Basic Auth is used. I assume you're using some form of Forms based authentication.

From recollection, Windows Challenge Response uses a different scheme and different arguments.

The trick is that it's up to the browser to determine what schemes it supports and how it responds to them.

My gut feel if you are using forms based authentication is to stay with the 200 + relogin page but add a custom header that the browser will ignore but your AJAX can identify.

For a really good User + AJAX experience, get the script to hang on to the AJAX request that found the session expired, fire off a relogin request via a popup, and on success, resubmit the original AJAX request and carry on as normal.

Avoid the cheat that just gets the script to hit the site every 5 mins to keep the session alive cause that just defeats the point of session expiry.

The other alternative is burn the AJAX request but that's a poor user experience.

Step 1 : Create two view inside a linear layout

Step 2 : First view must set to android:layout_weight="1"

Step 3 : Second view will automatically putted downwards

<LinearLayout
android:id="@+id/botton_header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >

    <View
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1" />

    <Button
    android:id="@+id/btn_health_advice"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>


</LinearLayout>

In Command line we can check our installed ng version.

ng -v OR ng --version OR ng version

This will give you like this :

 _                      _                 ____ _     ___

   / \   _ __   __ _ _   _| | __ _ _ __     / ___| |   |_ _|
  / ? \ | '_ \ / _` | | | | |/ _` | '__|   | |   | |    | |
 / ___ \| | | | (_| | |_| | | (_| | |      | |___| |___ | |
/_/   \_\_| |_|\__, |\__,_|_|\__,_|_|       \____|_____|___|
               |___/

Angular CLI: 1.6.5
Node: 8.0.0
OS: linux x64

If you want just the summary of the exception use:

    try
    {
        test();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }

If you want to see the whole stack trace (usually better for debugging) use:

    try
    {
        test();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }

Another method I sometime use is:

    private DoSomthing(int arg1, int arg2, out string errorMessage)
    {
         int result ;
        errorMessage = String.Empty;
        try 
        {           
            //do stuff
            int result = 42;
        }
        catch (Exception ex)
        {

            errorMessage = ex.Message;//OR ex.ToString(); OR Free text OR an custom object
            result = -1;
        }
        return result;
    }

And In your form you will have something like:

    string ErrorMessage;
    int result = DoSomthing(1, 2, out ErrorMessage);
    if (!String.IsNullOrEmpty(ErrorMessage))
    {
        MessageBox.Show(ErrorMessage);
    }

How about some Regex?

I wrote this for a text a file, but I believe this could work for you

(In case your text file contains line starting exactly with the "matched" ones below - simply adapt your Regex)

    private static List<string> fileUploadRequestParser(Stream stream)
    {
        //-----------------------------111111111111111
        //Content-Disposition: form-data; name="file"; filename="data.txt"
        //Content-Type: text/plain
        //...
        //...
        //-----------------------------111111111111111
        //Content-Disposition: form-data; name="submit"
        //Submit
        //-----------------------------111111111111111--

        List<String> lstLines = new List<string>();
        TextReader textReader = new StreamReader(stream);
        string sLine = textReader.ReadLine();
        Regex regex = new Regex("(^-+)|(^content-)|(^$)|(^submit)", RegexOptions.IgnoreCase | RegexOptions.Compiled | RegexOptions.Singleline);

        while (sLine != null)
        {
            if (!regex.Match(sLine).Success)
            {
                lstLines.Add(sLine);
            }
            sLine = textReader.ReadLine();
        }

        return lstLines;
    }

Switching to another branch in git. Straightforward answer,

git-checkout - Switch branches or restore working tree files

git fetch origin         <----this will fetch the branch
git checkout branch_name <--- Switching the branch

Before switching the branch make sure you don't have any modified files, in that case, you can commit the changes or you can stash it.

Just in case anyone falls here, the (only) solution that worked for me is creating the OkHttpClient like explained here.

Here is the code:

private static OkHttpClient getUnsafeOkHttpClient() {
  try {
    // Create a trust manager that does not validate certificate chains
    final TrustManager[] trustAllCerts = new TrustManager[] {
        new X509TrustManager() {
          @Override
          public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
          }

          @Override
          public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
          }

          @Override
          public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return new java.security.cert.X509Certificate[]{};
          }
        }
    };

    // Install the all-trusting trust manager
    final SSLContext sslContext = SSLContext.getInstance("SSL");
    sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
    // Create an ssl socket factory with our all-trusting manager
    final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

    OkHttpClient.Builder builder = new OkHttpClient.Builder();
    builder.sslSocketFactory(sslSocketFactory, (X509TrustManager)trustAllCerts[0]);
    builder.hostnameVerifier(new HostnameVerifier() {
      @Override
      public boolean verify(String hostname, SSLSession session) {
        return true;
      }
    });

    OkHttpClient okHttpClient = builder.build();
    return okHttpClient;
  } catch (Exception e) {
    throw new RuntimeException(e);
  }
}

I had this problem for our FSharp targets (FSharpTargetsPath was empty).

Many of the paths are built with reference to the VS version.

For various reasons, our build runs with system privileges, and the environment variable "VisualStudioVersion" was only set (by the VS 2013 installer) at the "user" level - which is fair enough.

Ensure that the "VisualStudioVersion" environment variable is set to "12.0" at the level (System or User) that you are running at.

The good news is a transaction in SQL Server can span multiple batches (each exec is treated as a separate batch.)

You can wrap your EXEC statements in a BEGIN TRANSACTION and COMMIT but you'll need to go a step further and rollback if any errors occur.

Ideally you'd want something like this:

BEGIN TRY
    BEGIN TRANSACTION 
        exec( @sqlHeader)
        exec(@sqlTotals)
        exec(@sqlLine)
    COMMIT
END TRY
BEGIN CATCH

    IF @@TRANCOUNT > 0
        ROLLBACK
END CATCH

The BEGIN TRANSACTION and COMMIT I believe you are already familiar with. The BEGIN TRY and BEGIN CATCH blocks are basically there to catch and handle any errors that occur. If any of your EXEC statements raise an error, the code execution will jump to the CATCH block.

Your existing SQL building code should be outside the transaction (above) as you always want to keep your transactions as short as possible.

I added it for all fieldsets with

fieldset {
        border: 1px solid lightgray;
    }

I didnt work if I set it separately using for example

border-color : red

. Then a black line was drawn next to the red line.

If you need to convert the dictionary to binary, you need to convert it to a string (JSON) as described in the previous answer, then you can convert it to binary.

For example:

my_dict = {'key' : [1,2,3]}

import json
def dict_to_binary(the_dict):
    str = json.dumps(the_dict)
    binary = ' '.join(format(ord(letter), 'b') for letter in str)
    return binary


def binary_to_dict(the_binary):
    jsn = ''.join(chr(int(x, 2)) for x in the_binary.split())
    d = json.loads(jsn)  
    return d

bin = dict_to_binary(my_dict)
print bin

dct = binary_to_dict(bin)
print dct

will give the output

1111011 100010 1101011 100010 111010 100000 1011011 110001 101100 100000 110010 101100 100000 110011 1011101 1111101

{u'key': [1, 2, 3]}

Using 2.0 and 4.0 assemblies together isn't quite straight forward.

The ORDER of the supported framework declarations in app.config actually have an effect on the exception of mixed mode being thrown. If you flip the declaration order you will get mixed mode error. This is the purpose of this answer.

So if you get the error in a Windows Forms app, , try this, mostly Windows Forms apps.

  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0,Profile=Client"/>
    <supportedRuntime version="v2.0.50727"></supportedRuntime>
  </startup>

Or if the project is not Windows Form. In a Web project add this to web.config file.

  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
    <supportedRuntime version="v2.0.50727"></supportedRuntime>
  </startup>

I'm a little confused. "foo.html" is just the name of your template. There's no inherent relationship between the route name "foo" and the template name "foo.html".

To achieve the goal of not rewriting logic code for two different routes, I would just define a function and call that for both routes. I wouldn't use redirect because that actually redirects the client/browser which requires them to load two pages instead of one just to save you some coding time - which seems mean :-P

So maybe:

def super_cool_logic():
    # execute common code here

@app.route("/foo")
def do_foo():
    # do some logic here
    super_cool_logic()
    return render_template("foo.html")

@app.route("/baz")
def do_baz():
    if some_condition:
        return render_template("baz.html")
    else:
        super_cool_logic()
        return render_template("foo.html", messages={"main":"Condition failed on page baz"})

I feel like I'm missing something though and there's a better way to achieve what you're trying to do (I'm not really sure what you're trying to do)

The below code this will help you

Why not just use substring... string.substring(0, 7); The first argument (0) is the starting point. The second argument (7) is the ending point (exclusive). More info here.

var string = "this is a string";
var length = 7;
var trimmedString = string.substring(0, length);

Getters and Setters in C# are something that simplifies the code.

private string name = "spots";

public string Name
{
    get { return name; }
    set { name = value; }
}

And calling it (assume we have a person obj with a name property):

Console.WriteLine(Person.Name); //prints "spots"
Person.Name = "stops";
Console.Writeline(Person.Name); //prints "stops"

This simplifies your code. Where in Java you might have to have two methods, one to Get() and one to Set() the property, in C# it is all done in one spot. I usually do this at the start of my classes:

public string foobar {get; set;}

This creates a getter and setter for my foobar property. Calling it is the same way as shown before. Somethings to note are that you don't have to include both get and set. If you don't want the property being modified, don't include set!

An XML declaration is not required in all XML documents; however XHTML document authors are strongly encouraged to use XML declarations in all their documents. Such a declaration is required when the character encoding of the document is other than the default UTF-8 or UTF-16 and no encoding was determined by a higher-level protocol. Here is an example of an XHTML document. In this example, the XML declaration is included.

<?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE html 
 PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
 <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
  <head>
    <title>Virtual Library</title>
  </head>
  <body>
    <p>Moved to <a href="http://example.org/">example.org</a>.</p>
 </body>
</html>

Please refer to the W3 standards for XML.

There is also:

try:
    del mydict[key]
except KeyError:
    pass

This only does 1 lookup instead of 2. However, except clauses are expensive, so if you end up hitting the except clause frequently, this will probably be less efficient than what you already have.

git --work-tree=/tmp/files_without_dot_git clone --depth=1 \
  https://git.yourgit.your.com/myawesomerepo.git \
  /tmp/deleteme_contents_of_dot_git

Both the directories in /tmp are created on the fly. No need to pre-create these.

You can do this with the standard Linq.ToLookup(). This will create a collection of values for each unique key. Just select the first item in the collection

Persons.ToLookup(p => p.Id).Select(coll => coll.First());

If you have a string and you know the index you want to put the two variables in the string you can use:

string temp = temp.Substring(0,index) + textbox1.Text + ":" + textbox2.Text +temp.Substring(index);

But if it is a simple line you can use it this way:

string temp = string.Format("your text goes here {0} rest of the text goes here : {1} , textBox1.Text , textBox2.Text ) ;"

You can use Substring:

string b = a.Substring(0,3);

Indeed, you can use the "create" method of Mongoose, it can contain an array of documents, see this example:

Candy.create({ candy: 'jelly bean' }, { candy: 'snickers' }, function (err, jellybean, snickers) {
});

The callback function contains the inserted documents. You do not always know how many items has to be inserted (fixed argument length like above) so you can loop through them:

var insertedDocs = [];
for (var i=1; i<arguments.length; ++i) {
    insertedDocs.push(arguments[i]);
}

Update: A better solution

A better solution would to use Candy.collection.insert() instead of Candy.create() - used in the example above - because it's faster (create() is calling Model.save() on each item so it's slower).

See the Mongo documentation for more information: http://docs.mongodb.org/manual/reference/method/db.collection.insert/
