Programs & Examples On #Indicator

The documentation on this is pretty clear. It's a UIView subclass so you use it like any other view. To start/stop the animation you use

[activityIndicator startAnimating];
[activityIndicator stopAnimating];

This is what I have after doing purge of all the python versions and reinstalling only 3.6.

I am totally noob at Linux, I just wanted to update Python from 2.x to 3.x so that Platformio could upgrade and now I messed up everything it seems.

If you are listening to the dragstop or other events, the original position should be a ui parameter:

dragstop: function(event, ui) {
    var originalPosition = ui.originalPosition;
}

Otherwise, I believe the only way to get it is:

draggable.data("draggable").originalPosition

Where draggable is the object you are dragging. The second version is not guaranteed to work in future versions of jQuery.

I was also facing the same issue, then i tried restarting my system after every change and it worked for me:

1. Uninstall Apache2.4 in cmd prompt (run administrator) with the command: httpd -k uninstall.
2. Restart the system.
3. open cmd prompt (run administrator) with the command: httpd -k install.
4. Then httpd -k install.

Hope you find useful.

Just had the same problem.

I'm using EF 6, Code First + Migrations. The problem was that our DBA created a constraint on the table that threw the error.

use now() in any cell. then use that cell as a "dummy" parameter in a function. when now() changes every minute the formula recalculates. example: someFunction(a1,b1,c1) * (cell with now() / cell with now())

You can't add them directly, you have to make a new array and then copy each of the arrays into the new one. System.arraycopy is a method you can use to perform this copy.

int[] array1and2 = new int[array1.length + array2.length];
System.arraycopy(array1, 0, array1and2, 0, array1.length);
System.arraycopy(array2, 0, array1and2, array1.length, array2.length);

This will work regardless of the size of array1 and array2.

Basically same as the accepted answer, but updated with new type and multiple country restrictions:

function initialize() {

 var options = {
  types: ['(regions)'],
  componentRestrictions: {country: ["us", "de"]}
 };

 var input = document.getElementById('searchTextField');
 var autocomplete = new google.maps.places.Autocomplete(input, options);
}

Using '(regions)' instead of '(cities)' allows to search by postal code as well as city name.

See official documentation, Table 3: https://developers.google.com/places/supported_types

You could do:

class myClass : ICloneable
{
    public String test;
    public object Clone()
    {
        return this.MemberwiseClone();
    }
}

then you can do

myClass a = new myClass();
myClass b = (myClass)a.Clone();

N.B. MemberwiseClone() Creates a shallow copy of the current System.Object.

This is a clean version remove query parameter with the URL class for today browsers:

function removeUrlParameter(url, paramKey)
{
  var r = new URL(url);
  r.searchParams.delete(paramKey);
  return r.href;
}

URLSearchParams not supported on old browsers

https://caniuse.com/#feat=urlsearchparams

IE, Edge (below 17) and Safari (below 10.3) do not support URLSearchParams inside URL class.

Polyfills

URLSearchParams only polyfill

This sort of approach should work.

var plugin_exists = true;

try {
  // some code that requires that plugin here
} catch(err) {
  plugin_exists = false;
}

No. JavaScript is automatically garbage collected; the object's memory will be reclaimed only if the GC decides to run and the object is eligible for collection.

Seeing as that will happen automatically as required, what would be the purpose of reclaiming the memory explicitly?

I ended up using:

Function DirectoryExists(Directory As String) As Boolean
    DirectoryExists = False
    If Len(Dir(Directory, vbDirectory)) > 0 Then
        If (GetAttr(Directory) And vbDirectory) = vbDirectory Then
            DirectoryExists = True
        End If
    End If
End Function

which is a mix of @Brian and @ZygD answers. Where I think @Brian's answer is not enough and don't like the On Error Resume Next used in @ZygD's answer

Configuring a working email client from localhost is quite a chore, I have spent hours of frustration attempting it. At last I have found this way to send mails (using WAMP, XAMPP, etc.):

Install hMailServer

Configure this hMailServer setting:

1. Open hMailServer Administrator.
2. Click the "Add domain ..." button to create a new domain.
3. Under the domain text field, enter your computer's localhost IP.
   • Example: 127.0.0.1 is your localhost IP.
4. Click the "Save" button.
5. Now go to Settings > Protocols > SMTP and select the "Delivery of Email" tab.
6. Find the localhost field enter "localhost".
7. Click the Save button.

Configure your Gmail account, perform following modification:

1. Go to Settings > Protocols > SMTP and select "Delivery of Email" tab.
2. Enter "smtp.gmail.com" in the Remote Host name field.
3. Enter "465" as the port number.
4. Check "Server requires authentication".
5. Enter your Google Mail address in the Username field.
6. Enter your Google Mail password in the password field.
7. Check mark "Use SSL"
8. Save all changes.

Optional

If you want to send email from another computer you need to allow deliveries from External to External accounts by following steps:

1. Go to Settings > Advanced > IP Ranges and double click on "My Computer" which should have IP address of 127.0.0.1
2. Check the Allow Deliveries from External to External accounts Checkbox.
3. Save settings using Save button.

 SELECT * FROM ALL_source WHERE UPPER(text) LIKE '%BLAH%'

EDIT Adding additional info:

 SELECT * FROM DBA_source WHERE UPPER(text) LIKE '%BLAH%'

The difference is dba_source will have the text of all stored objects. All_source will have the text of all stored objects accessible by the user performing the query. Oracle Database Reference 11g Release 2 (11.2)

Another difference is that you may not have access to dba_source.

It is usually a good idea to declare variables as unsigned or size_t if they will be compared to sizes, to avoid this issue. Whenever possible, use the exact type you will be comparing against (for example, use std::string::size_type when comparing with a std::string's length).

Compilers give warnings about comparing signed and unsigned types because the ranges of signed and unsigned ints are different, and when they are compared to one another, the results can be surprising. If you have to make such a comparison, you should explicitly convert one of the values to a type compatible with the other, perhaps after checking to ensure that the conversion is valid. For example:

unsigned u = GetSomeUnsignedValue();
int i = GetSomeSignedValue();

if (i >= 0)
{
    // i is nonnegative, so it is safe to cast to unsigned value
    if ((unsigned)i >= u)
        iIsGreaterThanOrEqualToU();
    else
        iIsLessThanU();
}
else
{
    iIsNegative();
}

With quotes around the date:

mysql> CALL insertEvent('2012.01.01 12:12:12');

This can occur when you are showing the dialog for a context that no longer exists. A common case - if the 'show dialog' operation is after an asynchronous operation, and during that operation the original activity (that is to be the parent of your dialog) is destroyed. For a good description, see this blog post and comments:

http://dimitar.me/android-displaying-dialogs-from-background-threads/

From the stack trace above, it appears that the facebook library spins off the auth operation asynchronously, and you have a Handler - Callback mechanism (onComplete called on a listener) that could easily create this scenario.

When I've seen this reported in my app, its pretty rare and matches the experience in the blog post. Something went wrong for the activity/it was destroyed during the work of the the AsyncTask. I don't know how your modification could result in this every time, but perhaps you are referencing an Activity as the context for the dialog that is always destroyed by the time your code executes?

Also, while I'm not sure if this is the best way to tell if your activity is running, see this answer for one method of doing so:

Check whether activity is active

If it's a framework-dependent application (the default), you run it by dotnet yourapp.dll.

If it's a self-contained application, you run it using yourapp.exe on Windows and ./yourapp on Unix.

For more information about the differences between the two app types, see the .NET Core Application Deployment article on .Net Docs.

Very basic, but does what you need without any addon modules or PS version requirements:

while ($true) {Clear-Host; gc E:\test.txt | select -last 3; sleep 2 }

The semicolon character is used to terminate the SQL statement.

You can either use # signs around a date value or use Access's (ACE, Jet, whatever) cast to DATETIME function CDATE(). As its name suggests, DATETIME always includes a time element so your literal values should reflect this fact. The ISO date format is understood perfectly by the SQL engine.

Best not to use BETWEEN for DATETIME in Access: it's modelled using a floating point type and anyhow time is a continuum ;)

DATE and TABLE are reserved words in the SQL Standards, ODBC and Jet 4.0 (and probably beyond) so are best avoided for a data element names:

Your predicates suggest open-open representation of periods (where neither its start date or the end date is included in the period), which is arguably the least popular choice. It makes me wonder if you meant to use closed-open representation (where neither its start date is included but the period ends immediately prior to the end date):

SELECT my_date
  FROM MyTable
 WHERE my_date >= #2008-09-01 00:00:00#
       AND my_date < #2010-09-01 00:00:00#;

Alternatively:

SELECT my_date
  FROM MyTable
 WHERE my_date >= CDate('2008-09-01 00:00:00')
       AND my_date < CDate('2010-09-01 00:00:00'); 

You want this:

curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);  

Zend has a REST client and zend_http_client and I'm sure PEAR has some sort of wrapper. But its easy enough to do on your own.

So the entire request might look something like this:

$ch = curl_init($host);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/xml', $additionalHeaders));
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payloadName);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$return = curl_exec($ch);
curl_close($ch);

object.__del__(self) is called when the instance is about to be destroyed.

>>> class Test:
...     def __del__(self):
...         print "deleted"
... 
>>> test = Test()
>>> del test
deleted

Object is not deleted unless all of its references are removed(As quoted by ethan)

Also, From Python official doc reference:

del x doesn’t directly call x.del() — the former decrements the reference count for x by one, and the latter is only called when x‘s reference count reaches zero

This should work for both strings and unicode objects in Python2, and both strings and bytes in Python3:

# python <3.0
def only_numerics(seq):
    return filter(type(seq).isdigit, seq)

# python =3.0
def only_numerics(seq):
    seq_type= type(seq)
    return seq_type().join(filter(seq_type.isdigit, seq))

For future readers who faced same issue with Windows Forms Application, one solution is to add these lines to your main/start up form class:

    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new MyMainForm());
    }

Then go to project properties > Application > Startup Object dropdown, should see the namespace.MyMainForm, select it, clean and build the solution. And it should work.

In general you can concatenate a whole sequence of arrays along any axis:

numpy.concatenate( LIST, axis=0 )

but you do have to worry about the shape and dimensionality of each array in the list (for a 2-dimensional 3x5 output, you need to ensure that they are all 2-dimensional n-by-5 arrays already). If you want to concatenate 1-dimensional arrays as the rows of a 2-dimensional output, you need to expand their dimensionality.

As Jorge's answer points out, there is also the function stack, introduced in numpy 1.10:

numpy.stack( LIST, axis=0 )

This takes the complementary approach: it creates a new view of each input array and adds an extra dimension (in this case, on the left, so each n-element 1D array becomes a 1-by-n 2D array) before concatenating. It will only work if all the input arrays have the same shape—even along the axis of concatenation.

vstack (or equivalently row_stack) is often an easier-to-use solution because it will take a sequence of 1- and/or 2-dimensional arrays and expand the dimensionality automatically where necessary and only where necessary, before concatenating the whole list together. Where a new dimension is required, it is added on the left. Again, you can concatenate a whole list at once without needing to iterate:

numpy.vstack( LIST )

This flexible behavior is also exhibited by the syntactic shortcut numpy.r_[ array1, ...., arrayN ] (note the square brackets). This is good for concatenating a few explicitly-named arrays but is no good for your situation because this syntax will not accept a sequence of arrays, like your LIST.

There is also an analogous function column_stack and shortcut c_[...], for horizontal (column-wise) stacking, as well as an almost-analogous function hstack—although for some reason the latter is less flexible (it is stricter about input arrays' dimensionality, and tries to concatenate 1-D arrays end-to-end instead of treating them as columns).

Finally, in the specific case of vertical stacking of 1-D arrays, the following also works:

numpy.array( LIST )

...because arrays can be constructed out of a sequence of other arrays, adding a new dimension to the beginning.

if you using Generic Array List with Class instead of specific type like

EX:

private ArrayList<Model> aListModel = new ArrayList<Model>();

Here, Model = Class

Receiving Intent Like :

aListModel = (ArrayList<Model>) getIntent().getSerializableExtra(KEY);

MUST REMEMBER:

Here Model-class must be implemented like: ModelClass implements Serializable

<ul>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
  <li>this is my text</li>
</ul>

you can use this simple css style

ul {
     list-style-type: '\2713';
   }

Okay, so I know I'm way late to the party. Like 6 years late but this was something I needed to figure out and have it formatted YYYY-MM-DD.

moment().format(moment.HTML5_FMT.DATE); // 2019-11-08

You can also pass in a parameter like, 2019-11-08T17:44:56.144.

moment("2019-11-08T17:44:56.144").format(moment.HTML5_FMT.DATE); // 2019-11-08

https://momentjs.com/docs/#/parsing/special-formats/

an abstract method must be call override in derived class other wise it will give compile-time error and in virtual you may or may not override it's depend if it's good enough use it

Example:

abstract class twodshape
{
    public abstract void area(); // no body in base class
}

class twodshape2 : twodshape
{
    public virtual double area()
    {
        Console.WriteLine("AREA() may be or may not be override");
    }
}

The problem with your code seems to be the elseif-statement which should be else if (Notice the space).

I rewrote and simplyfied the code to this:

$(document).ready(function () {

    if (screen.width < 1024) {
        $(".yourClass").hide();
    }
    else {

        $(".yourClass").show();
    }

});

First, you have to write in XML layout:

android:visibility="invisible" <!--or set VISIBLE-->

then use this to show it using Java:

myimage.setVisibility(SHOW); //HIDE

There are various ways to achieve this. Here are three.

    Map<String, String> map = new HashMap<String, String>();
    map.put("key1", "value1");
    map.put("key2", "value2");
    map.put("key3", "value3");

    System.out.println("using entrySet and toString");
    for (Entry<String, String> entry : map.entrySet()) {
        System.out.println(entry);
    }
    System.out.println();

    System.out.println("using entrySet and manual string creation");
    for (Entry<String, String> entry : map.entrySet()) {
        System.out.println(entry.getKey() + "=" + entry.getValue());
    }
    System.out.println();

    System.out.println("using keySet");
    for (String key : map.keySet()) {
        System.out.println(key + "=" + map.get(key));
    }
    System.out.println();

Output

using entrySet and toString
key1=value1
key2=value2
key3=value3

using entrySet and manual string creation
key1=value1
key2=value2
key3=value3

using keySet
key1=value1
key2=value2
key3=value3

because your jQuery code is wrong. Correctly would be:

var theParent = $(this).parent().get(0); 
$(theParent).css('z-index', 3000);

Try reinstall by using the below link,

Download https://bootstrap.pypa.io/get-pip.py

After download, copy the "get-pip.py" to python installed main dirctory, then open cmd and navigate to python directory and type "python get-pip.py" (without quotes)

Note: Also make sure the python directory is set in the environmental variable.

Hope this might help.

put following code in your page

  Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequest);
    function EndRequest(sender, args) {
        if (args.get_error() == undefined) {
        $('.dropdown-toggle').dropdown();
        }
    }

Here's one way to do it:

if not any(d['main_color'] == 'red' for d in a):
    # does not exist

The part in parentheses is a generator expression that returns True for each dictionary that has the key-value pair you are looking for, otherwise False.

If the key could also be missing the above code can give you a KeyError. You can fix this by using get and providing a default value. If you don't provide a default value, None is returned.

if not any(d.get('main_color', default_value) == 'red' for d in a):
    # does not exist

You have to use either DQL or the QueryBuilder. E.g. in your Purchase-EntityRepository you could do something like this:

$q = $this->createQueryBuilder('p')
          ->where('p.prize > :purchasePrize')
          ->setParameter('purchasePrize', 200)
          ->getQuery();

$q->getResult();

For even more complex scenarios take a look at the Expr() class.

Encountered similar problem: parsing CSV file with special characters like é, è, ö etc ...

The following worked fine for me:

To represent the characters correctly on the html page, the header was needed :

header('Content-Type: text/html; charset=UTF-8');

In order to parse every character correctly, I used:

utf8_encode(fgets($file));

Dont forget to use in all following string operations the 'Multibyte String Functions', like:

mb_strtolower($value, 'UTF-8');

Using multiple threads on CPython won't give you better performance for pure-Python code due to the global interpreter lock (GIL). I suggest using the multiprocessing module instead:

pool = multiprocessing.Pool(4)
out1, out2, out3 = zip(*pool.map(calc_stuff, range(0, 10 * offset, offset)))

Note that this won't work in the interactive interpreter.

To avoid the usual FUD around the GIL: There wouldn't be any advantage to using threads for this example anyway. You want to use processes here, not threads, because they avoid a whole bunch of problems.

just give

a{
color:blue
}

even if its is visited it will always be blue

check this below code. this is for dropdown menu. In this if we select others then the text box will show otherwise text box will hide.

I have found this class very helpful to handle with resources. It has some defined methods to deal with dimens, colors, drawables and strings, like this one:

public static String getString(Context context, String stringId) {
    int sid = getStringId(context, stringId);
    if (sid > 0) {
        return context.getResources().getString(sid);
    } else {
        return "";
    }
}

You can use the invert (~) operator (which acts like a not for boolean data):

new_df = df[~df["col"].str.contains(word)]

, where new_df is the copy returned by RHS.

contains also accepts a regular expression...

If the above throws a ValueError, the reason is likely because you have mixed datatypes, so use na=False:

new_df = df[~df["col"].str.contains(word, na=False)]

Or,

new_df = df[df["col"].str.contains(word) == False]

As ant31 already pointed out you can use the synchronize module to this. By default, the module transfers files between the control machine and the current remote host (inventory_host), however that can be changed using the task's delegate_to parameter (it's important to note that this is a parameter of the task, not of the module).

You can place the task on either ServerA or ServerB, but you have to adjust the direction of the transfer accordingly (using the mode parameter of synchronize).

Placing the task on ServerB

- hosts: ServerB
  tasks:
    - name: Transfer file from ServerA to ServerB
      synchronize:
        src: /path/on/server_a
        dest: /path/on/server_b
      delegate_to: ServerA

This uses the default mode: push, so the file gets transferred from the delegate (ServerA) to the current remote (ServerB).

This might sound like strange, since the task has been placed on ServerB (via hosts: ServerB). However, one has to keep in mind that the task is actually executed on the delegated host, which in this case is ServerA. So pushing (from ServerA to ServerB) is indeed the correct direction. Also remember that we cannot simply choose not to delegate at all, since that would mean that the transfer happens between the control machine and ServerB.

Placing the task on ServerA

- hosts: ServerA
  tasks:
    - name: Transfer file from ServerA to ServerB
      synchronize:
        src: /path/on/server_a
        dest: /path/on/server_b
        mode: pull
      delegate_to: ServerB

This uses mode: pull to invert the transfer direction. Again, keep in mind that the task is actually executed on ServerB, so pulling is the right choice.

You should probably use SQL_Latin1_General_Cp1_CI_AS_KI_WI as your collation. The one you specify in your question is explictly case sensitive.

You can see a list of collations here.

I see it hinted here and there, but you could also do a faster calculation first, like, compare the bounding boxes for overlap, and THEN do a radius-based overlap if that first test passes.

The addition/difference math is much faster for a bounding box than all the trig for the radius, and most times, the bounding box test will dismiss the possibility of a collision. But if you then re-test with trig, you're getting the accurate results that you're seeking.

Yes, it's two tests, but it will be faster overall.

ALTER TABLE [Employee]
ALTER COLUMN [Salary] NUMERIC(22,5) NOT NULL

I did this solution: if you want plot more than one plot in one figure, make sure before plotting next plots you have set right matplotlib.pyplot.hold(True) to able adding another plots.

Concerning the datetime values on the X axis, a solution using the alignment of bars works for me. When you create another bar plot with matplotlib.pyplot.bar(), just use align='edge|center' and set width='+|-distance'.

When you set all bars (plots) right, you will see the bars fine.

Also the $wshell = New-Object -ComObject wscript.shell; helped a script that was running in the background, it worked fine with just but adding $wshell. fixed it from running as background! [Microsoft.VisualBasic.Interaction]::AppActivate("App Name")

This should work

gsub('\u009c','','\u009cYes yes for ever for ever the boys ')
"Yes yes for ever for ever the boys "

Here 009c is the hexadecimal number of unicode. You must always specify 4 hexadecimal digits. If you have many , one solution is to separate them by a pipe:

gsub('\u009c|\u00F0','','\u009cYes yes \u00F0for ever for ever the boys and the girls')

"Yes yes for ever for ever the boys and the girls"

I have a much easier way than the above ones.

DECLARE @FirstId int, @SecondId int

    SELECT TOP 1 @FirstId = TableId from MyDataTable ORDER BY TableId 
    SELECT TOP 1 @SecondId = TableId from MyDataTable WHERE TableId <> @FirstId  ORDER BY TableId 

SELECT @SecondId 

You can hide an image using javascript like this:

document.images['imageName'].style.visibility = hidden;

If that isn't what you are after, you need to explain yourself more clearly.

This link has the break down

http://clang.llvm.org/docs/AutomaticReferenceCounting.html#ownership.spelling.property

assign implies __unsafe_unretained ownership.

copy implies __strong ownership, as well as the usual behavior of copy semantics on the setter.

retain implies __strong ownership.

strong implies __strong ownership.

unsafe_unretained implies __unsafe_unretained ownership.

weak implies __weak ownership.

I had this issue when I was trying to make my Docker container smaller. It was because I'd installed Python 2.7 with:

apt-get install -y --no-install-recommends python

And I should not have included the --no-install-recommends flag:

apt-get install -y python

This can be done in C++11

#include <map>
enum MyEnum { AA, BB, CC, DD };

static std::map< MyEnum, const char * > info = {
   {AA, "This is an apple"},
   {BB, "This is a book"},
   {CC, "This is a coffee"},
   {DD, "This is a door"}
};

void main()
{
    std::cout << info[AA] << endl
              << info[BB] << endl
              << info[CC] << endl
              << info[DD] << endl;
}

All the magic on iOS only goes with using source with the file, where you export your environment variables.

For example:

You can create an file like this:

export bim=fooo
export bom=bar

Save this file as bimbom.env, and do source ./bimbom.ev. Voilá, you got your environment variables.

Check them with:

echo $bim

Instead of using $http.get('abc/xyz/getSomething') try to use $http.jsonp('abc/xyz/getSomething')

     return{
            getList:function(){
                return $http.jsonp('http://localhost:8080/getNames');
            }
        }

`

require_once('functions.php');

$errors = FALSE;
$errorMessage = "";

if(mysqli_connect_error()){
  $errors = TRUE;
  $errorMessage .= "There was a connection error <br/>";
  errorDisplay($errorMessage);
  die($errors);
} else if($errors != "TRUE"){
  $errors .= FALSE;
}

if(isset(mysqli_real_escape_string($_POST['search']))){
  $search = mysqli_real_escape_string($_POST['search']);
  search(search);
}



?>
<?php
//This is functions.php
function search($searchQuery){
  echo "<div class="col-md-10 col-md-offset-1">";
  $searchTerm
  $query = query("SELECT * FROM `index` WHERE `keywords` LIKE '".$searchTerm."' ");
  while($row = mysqli_fetch_array($query)){
    $results = <<< DELIMITER
      <div class="result col-md-12">
        <a href="index.php?search={$row['id']}"> {$row['Title']} </a>
        <p class="searchDesc">{$row['description']}</p>
      </div>
DELIMITER;
    echo $results;
  }
  echo "</div>";
}

function errorDisplay($msg){
  if(!isset($_SESSION['errors'])){
    $_SESSION['errors'] = $msg;
    showError($msg);
  } else if() {
    $_SESSION['errors'] .= $msg . "<br>";
    showError($msg);
  }
}
function showError($msg) {
  return $msg;
  unset($_SESSION['errors']);
}

Perhaps That Helps?

An idea would be that display:flex; with flex-direction: row; is filling the container div with .flex-1 and .flex-2, but that does not mean that .flex-2 has a default height:100%;, even if it is extended to full height.

And to have a child element (.flex-2-child) with height:100%;, you'll need to set the parent to height:100%; or use display:flex; with flex-direction: row; on the .flex-2 div too.

From what I know, display:flex will not extend all your child elements height to 100%.

A small demo, removed the height from .flex-2-child and used display:flex; on .flex-2: http://jsfiddle.net/2ZDuE/3/

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

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

Then add:

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

Finally, pass proxy-url to your script.

The compiler doesn't get the intricate logic where you return in the last iteration of the loop, so it thinks that you could exit out of the loop and end up not returning anything at all.

Instead of returning in the last iteration, just return true after the loop:

public static bool isTwenty(int num) {
  for(int j = 1; j <= 20; j++) {
    if(num % j != 0) {
      return false;
    }
  }
  return true;
}

Side note, there is a logical error in the original code. You are checking if num == 20 in the last condition, but you should have checked if j == 20. Also checking if num % j == 0 was superflous, as that is always true when you get there.

Also a possibility:

str.replace( /\s+/g, ' ' )

I was getting the same messages while I was running just msbuild from powershell.

dotnet msbuild "./project.csproj" worked for me.

In case you don't want to track table view's content size changes yourself, you might find this subclass useful.

protocol ContentFittingTableViewDelegate: UITableViewDelegate {
    func tableViewDidUpdateContentSize(_ tableView: UITableView)
}

class ContentFittingTableView: UITableView {

    override var contentSize: CGSize {
        didSet {
            if !constraints.isEmpty {
                invalidateIntrinsicContentSize()
            } else {
                sizeToFit()
            }

            if contentSize != oldValue {
                if let delegate = delegate as? ContentFittingTableViewDelegate {
                    delegate.tableViewDidUpdateContentSize(self)
                }
            }
        }
    }

    override var intrinsicContentSize: CGSize {
        return contentSize
    }

    override func sizeThatFits(_ size: CGSize) -> CGSize {
        return contentSize
    }
}

Try setting the HOME environment variable in Windows to your home folder (c:\users\username).

( you can confirm that this is the problem by doing echo $HOME in git bash and echo %HOME% in cmd - latter might not be available )

This will simply transform you first letter of text:

yourtext.substr(0,1).toUpperCase()+yourtext.substr(1);

This code shows how to use a java.text.SimpleDateFormat to parse a java.util.Date from a String:

String str = "Jun 13 2003 23:11:52.454 UTC";
SimpleDateFormat df = new SimpleDateFormat("MMM dd yyyy HH:mm:ss.SSS zzz");
Date date = df.parse(str);
long epoch = date.getTime();
System.out.println(epoch); // 1055545912454

Date.getTime() returns the epoch time in milliseconds.

Use this code

    ((RadioButton)findViewById(R.id.radio3)).setChecked(true);

mistake -> don't forget to give () for whole before setChecked() -> If u forget to do that setChecked() is not available for this radio button

Updates an old config with new/changed/removed options.

This will get the country code set for the phone (phones language, NOT user location):

 String locale = context.getResources().getConfiguration().locale.getCountry(); 

can also replace getCountry() with getISO3Country() to get a 3 letter ISO code for the country. This will get the country name:

 String locale = context.getResources().getConfiguration().locale.getDisplayCountry();

This seems easier than the other methods and rely upon the localisation settings on the phone, so if a US user is abroad they probably still want Fahrenheit and this will work :)

Editors note: This solution has nothing to do with the location of the phone. It is constant. When you travel to Germany locale will NOT change. In short: locale != location.

Use:

ii .

which is short for

Invoke-Item .

It is one of the most common things I type at the PowerShell command line.

It just happend to me. I solved the problem by tracing backward from the point ng-click is coded. Found out that an extra

</div> 

was placed in the html to prematurely close the div block that contains the ng-click.

Removed the extra

</div> 

then everything is working fine.

I usually send the text I want to copy as an sms message through telnet and then copy the text from the sms message. Here's how:

Connect through telnet:

• Syntax: telnet localhost <port>
• Example: telnet localhost 5554

(5554 is the default port. The title bar of the emulator shows the port that is being used, so you can see if it's different).

Send message:

• Syntax: sms send <senders phone number> <message>
• Example: sms send 1231231234 This is the message you want to send

(You can just make up the senders phone number)

This works really well for links as the message is automatically converted into a hyperlink which you can click without having to copy / paste it into the browser.

Once the emulator receives the message you can copy it and paste it wherever you like.

Try the clear property.

Remember that float removes an element from the document layout - so yes, in a way it is "interfering" with br and p tags, in the sense that it would basically be ignoring anything in the main flow layout.

Why don't you test this with this code:

File fdelete = new File(uri.getPath());
if (fdelete.exists()) {
    if (fdelete.delete()) {
        System.out.println("file Deleted :" + uri.getPath());
    } else {
        System.out.println("file not Deleted :" + uri.getPath());
    }
}

I think part of the problem is you never try to delete the file, you just keep creating a variable that has a method call.

So in your case you could try:

File file = new File(uri.getPath());
file.delete();
if(file.exists()){
      file.getCanonicalFile().delete();
      if(file.exists()){
           getApplicationContext().deleteFile(file.getName());
      }
}

However I think that's a little overkill.

You added a comment that you are using an external directory rather than a uri. So instead you should add something like:

String root = Environment.getExternalStorageDirectory().toString();
File file = new File(root + "/images/media/2918"); 

Then try to delete the file.

Ok, finally got it.

Change this line in %windir%\System32\inetsrv\Config\ApplicationHost.config

Solution:

sort -k 2 -n filename

more verbosely written as:

sort --key 2 --numeric-sort filename

Example:

$ cat filename
A 12
B 48
C 3

$ sort --key 2 --numeric-sort filename 
C 3
A 12
B 48

Explanation:

• -k # - this argument specifies the first column that will be used to sort. (note that column here is defined as a whitespace delimited field; the argument -k5 will sort starting with the fifth field in each line, not the fifth character in each line)

• -n - this option specifies a "numeric sort" meaning that column should be interpreted as a row of numbers, instead of text.

More:

Other common options include:

• -r - this option reverses the sorting order. It can also be written as --reverse.
• -i - This option ignores non-printable characters. It can also be written as --ignore-nonprinting.
• -b - This option ignores leading blank spaces, which is handy as white spaces are used to determine the number of rows. It can also be written as --ignore-leading-blanks.
• -f - This option ignores letter case. "A"=="a". It can also be written as --ignore-case.
• -t [new separator] - This option makes the preprocessing use a operator other than space. It can also be written as --field-separator.

There are other options, but these are the most common and helpful ones, that I use often.

Just use the LIMIT clause.

SELECT * FROM `msgtable` WHERE `cdate`='18/07/2012' LIMIT 10

And from the next call you can do this way:

SELECT * FROM `msgtable` WHERE `cdate`='18/07/2012' LIMIT 10 OFFSET 10

Add below lines to your project

    app.run(host = '0.0.0.0',port=5005)

Each key in a HashMap must be unique.

When "adding a duplicate key" the old value (for the same key, as keys must be unique) is simply replaced; see HashMap.put:

Associates the specified value with the specified key in this map. If the map previously contained a mapping for the key, the old value is replaced.

Returns the previous value associated with key, or null if there was no mapping for key.

As far as nulls: a single null key is allowed (as keys must be unique) but the HashMap can have any number of null values, and a null key need not have a null value. Per the documentation:

[.. HashMap] permits null values and [a] null key.

However, the documentation says nothing about null/null needing to be a specific key/value pair or null/"a" being invalid.

You can dynamically change color of any items ( layout, textview ) . Try below code to set color programmatically in layout

in activity.java file

String quote_bg_color = "#FFC107"
quoteContainer= (LinearLayout)view.findViewById(R.id.id_quotecontainer);
quoteContainer.setBackgroundResource(R.drawable.layout_round);
GradientDrawable drawable = (GradientDrawable) quoteContainer.getBackground();
drawable.setColor(Color.parseColor(quote_bg_color));

create layout_round.xml in drawable folder

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="@color/colorPrimaryLight"/>
    <stroke android:width="0dp" android:color="#B1BCBE" />
    <corners android:radius="10dp"/>
    <padding android:left="0dp" android:top="0dp" android:right="0dp" android:bottom="0dp" />
</shape>

layout in activity.xml file

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

----other components---

</LinearLayout>

  function setIframeHeight() {
      $('.iframe_fullHeight').each(
          function (i, item) {
              item.height = $(document).height();
          }
      );
  };

  $(document).ready( function () {
      setIframeHeight();
  });
  $(window).resize( function () {
      setIframeHeight();
  });
</script> 

The first half is from ???, and works when there is html in the iframe. The second half sets the iframe to page height (not content height), when iframes class is iframe_fullHeight. You can use this if the content is a PDF or other such like, but you have to set the class. Also can only be used when being full height is appropriate.

Note: for some reason, when it recalculates after window resize, it gets height wrong.

Well then: welcome to the R world ;-)

Here you go

Setting up the code

urls <- c(
    "http://stat.ethz.ch/R-manual/R-devel/library/base/html/connections.html",
    "http://en.wikipedia.org/wiki/Xz",
    "xxxxx"
)
readUrl <- function(url) {
    out <- tryCatch(
        {
            # Just to highlight: if you want to use more than one 
            # R expression in the "try" part then you'll have to 
            # use curly brackets.
            # 'tryCatch()' will return the last evaluated expression 
            # in case the "try" part was completed successfully

            message("This is the 'try' part")

            readLines(con=url, warn=FALSE) 
            # The return value of `readLines()` is the actual value 
            # that will be returned in case there is no condition 
            # (e.g. warning or error). 
            # You don't need to state the return value via `return()` as code 
            # in the "try" part is not wrapped inside a function (unlike that
            # for the condition handlers for warnings and error below)
        },
        error=function(cond) {
            message(paste("URL does not seem to exist:", url))
            message("Here's the original error message:")
            message(cond)
            # Choose a return value in case of error
            return(NA)
        },
        warning=function(cond) {
            message(paste("URL caused a warning:", url))
            message("Here's the original warning message:")
            message(cond)
            # Choose a return value in case of warning
            return(NULL)
        },
        finally={
        # NOTE:
        # Here goes everything that should be executed at the end,
        # regardless of success or error.
        # If you want more than one expression to be executed, then you 
        # need to wrap them in curly brackets ({...}); otherwise you could
        # just have written 'finally=<expression>' 
            message(paste("Processed URL:", url))
            message("Some other message at the end")
        }
    )    
    return(out)
}

Applying the code

> y <- lapply(urls, readUrl)
Processed URL: http://stat.ethz.ch/R-manual/R-devel/library/base/html/connections.html
Some other message at the end
Processed URL: http://en.wikipedia.org/wiki/Xz
Some other message at the end
URL does not seem to exist: xxxxx
Here's the original error message:
cannot open the connection
Processed URL: xxxxx
Some other message at the end
Warning message:

Additional remarks

tryCatch

tryCatch returns the value associated to executing expr unless there's an error or a warning. In this case, specific return values (see return(NA) above) can be specified by supplying a respective handler function (see arguments error and warning in ?tryCatch). These can be functions that already exist, but you can also define them within tryCatch() (as I did above).

The implications of choosing specific return values of the handler functions

As we've specified that NA should be returned in case of error, the third element in y is NA. If we'd have chosen NULL to be the return value, the length of y would just have been 2 instead of 3 as lapply() will simply "ignore" return values that are NULL. Also note that if you don't specify an explicit return value via return(), the handler functions will return NULL (i.e. in case of an error or a warning condition).

"Undesired" warning message

As warn=FALSE doesn't seem to have any effect, an alternative way to suppress the warning (which in this case isn't really of interest) is to use

suppressWarnings(readLines(con=url))

instead of

readLines(con=url, warn=FALSE)

Multiple expressions

Note that you can also place multiple expressions in the "actual expressions part" (argument expr of tryCatch()) if you wrap them in curly brackets (just like I illustrated in the finally part).

I use this and it works

public void Messagebox(string xMessage)
{
    Response.Write("<script>alert('" + xMessage + "')</script>");
}

And I call like this

    Messagebox("je suis la!");

Using only nltk tools

from nltk.tokenize import word_tokenize
from nltk.util import ngrams

def get_ngrams(text, n ):
    n_grams = ngrams(word_tokenize(text), n)
    return [ ' '.join(grams) for grams in n_grams]

Example output

get_ngrams('This is the simplest text i could think of', 3 )

['This is the', 'is the simplest', 'the simplest text', 'simplest text i', 'text i could', 'i could think', 'could think of']

In order to keep the ngrams in array format just remove ' '.join

you can initialize it to ' ' instead. Also, the reason that you received an error -1 being too many characters is because it is treating '-' and 1 as separate.

Replace your "Save" button with an anchor link and set the new download attribute dynamically. Works in Chrome and Firefox:

    }
    return keys

Deselect Hide Empty Middle Packages in Project Explorer Windows settings menu than you will be able to refactor each directory

I found the perfect way to Ignore files in TFS like SVN does.
First of all, select the file that you want to ignore (e.g. the Web.config).
Now go to the menu tab and select:

File Source control > Advanced > Exclude web.config from source control

... and boom; your file is permanently excluded from source control.

I'm developing with android studio 2+.

to create class diagrams I did the following: - install "ObjectAid UML Explorer" as plugin for eclipse(in my case luna with android sdk but works with younger versions as well) ... go to eclipse marketplace and search for "ObjectAid UML Explorer". it's further down in the search results. after installation and restart of eclipse ...

open an empty android or what-ever-java-project in eclipse. then right click on the empty eclipse project in the project explorer -> select 'build path' then I link my ANDROID STUDIO SRC PATH into my eclipse android project. doesn't matter if there are errors. again right click on the eclipse-android project and select: New in the filter type 'class' then you should see among others an option 'class diagram' ... select it and confgure it ... png stuff, visibility, etc. drag/drop your ANDROID STUDIO project classes into the open diagram -> voila :)

hth

I open eclipse(luna, but that doesn't matter). I got the "ObjectAid UML Explorer"
that installed I open an empty android project oin eclipse, right

Some threads do background tasks, like sending keepalive packets, or performing periodic garbage collection, or whatever. These are only useful when the main program is running, and it's okay to kill them off once the other, non-daemon, threads have exited.

Without daemon threads, you'd have to keep track of them, and tell them to exit, before your program can completely quit. By setting them as daemon threads, you can let them run and forget about them, and when your program quits, any daemon threads are killed automatically.

It enables error handling. The following is partly from https://msdn.microsoft.com/en-us/library/5hsw66as.aspx

' Enable error handling. When a run-time error occurs, control goes to the statement 
' immediately following the statement where the error occurred, and execution
' continues from that point.
On Error Resume Next

SomeCodeHere

If Err.Number = 0 Then
    WScript.Echo "No Error in SomeCodeHere."
Else
  WScript.Echo "Error in SomeCodeHere: " & Err.Number & ", " & Err.Source & ", " & Err.Description
  ' Clear the error or you'll see it again when you test Err.Number
  Err.Clear
End If

SomeMoreCodeHere

If Err.Number <> 0 Then
  WScript.Echo "Error in SomeMoreCodeHere:" & Err.Number & ", " & Err.Source & ", " & Err.Description
  ' Clear the error or you'll see it again when you test Err.Number
  Err.Clear
End If

' Disables enabled error handler in the current procedure and resets it to Nothing.
On Error Goto 0

' There are also `On Error Goto -1`, which disables the enabled exception in the current 
' procedure and resets it to Nothing, and `On Error Goto line`, 
' which enables the error-handling routine that starts at the line specified in the 
' required line argument. The line argument is any line label or line number. If a run-time 
' error occurs, control branches to the specified line, making the error handler active. 
' The specified line must be in the same procedure as the On Error statement, 
' or a compile-time error will occur.

ButterKnife is probably the best solution for the clutter problem. It uses annotation processors to generate the so called "old method" boilerplate code.

But the onClick method can still be used, with a custom inflator.

How to use

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup cnt, Bundle state) {
    inflater = FragmentInflatorFactory.inflatorFor(inflater, this);
    return inflater.inflate(R.layout.fragment_main, cnt, false);
}

Implementation

public class FragmentInflatorFactory implements LayoutInflater.Factory {

    private static final int[] sWantedAttrs = { android.R.attr.onClick };

    private static final Method sOnCreateViewMethod;
    static {
        // We could duplicate its functionallity.. or just ignore its a protected method.
        try {
            Method method = LayoutInflater.class.getDeclaredMethod(
                    "onCreateView", String.class, AttributeSet.class);
            method.setAccessible(true);
            sOnCreateViewMethod = method;
        } catch (NoSuchMethodException e) {
            // Public API: Should not happen.
            throw new RuntimeException(e);
        }
    }

    private final LayoutInflater mInflator;

            throw new NullPointerException();
        }
        mInflator = delegate;
        mFragment = fragment;

        FragmentInflatorFactory factory = new FragmentInflatorFactory(inflator, fragment);
        inflator.setFactory(factory);
        return inflator;
    }

    @Override

you can find the locked tables in oralce by querying with following query

    select
   c.owner,
   c.object_name,
   c.object_type,
   b.sid,
   b.serial#,
   b.status,
   b.osuser,
   b.machine
from
   v$locked_object a ,
   v$session b,
   dba_objects c
where
   b.sid = a.session_id
and
   a.object_id = c.object_id;

Check this: How to maximize a plt.show() window using Python

The command is different depending on which backend you use. I find that this is the best way to make sure the saved pictures have the same scaling as what I view on my screen.

Since I use Canopy with the QT backend:

pylab.get_current_fig_manager().window.showMaximized()

I then call savefig() as required with an increased DPI per silvado's answer.

If you're open to changing the original string, you can simply replace the delimiter with \0. The original pointer will point to the first string and the pointer to the character after the delimiter will point to the second string. The good thing is you can use both pointers at the same time without allocating any new string buffers.

just in case someone is getting NullPointerException, you need to get the context inside onCreate().

Service is a Context, so do this:

@Override
public void onCreate() {
    super.onCreate();
    context = this;
}

This will work for Linux, for example if you want to check if banshee is running... (banshee is a music player)

import subprocess

def running_process(process):
    "check if process is running. < process > is the name of the process."

    proc = subprocess.Popen(["if pgrep " + process + " >/dev/null 2>&1; then echo 'True'; else echo 'False'; fi"], stdout=subprocess.PIPE, shell=True)

    (Process_Existance, err) = proc.communicate()
    return Process_Existance

# use the function
print running_process("banshee")

I would suggest adding class no-js to your html to nest your CSS selectors under it like:

.loading {
    display: none;
 }

.no-js .loading {
 display: block;
 //....
}

and when you finish loading your credit code remove it:

$('html').removeClass('no-js');

This will hide your loading spinner as there's no no-js class in html it means you already loaded your credit code

Expanding @kravits88 answer:

This will stretch the buttons to fit whole width:

<div className="btn-group-justified">
<div className="btn-group">
  <button type="button" className="btn btn-primary">SAVE MY DEAR!</button>
</div>
<div className="btn-group">
  <button type="button" className="btn btn-default">CANCEL</button>
</div>
</div>

How about this?

https://maps.google.com/?q=1200 Pennsylvania Ave SE, Washington, District of Columbia, 20003

If you have lat-long then use below URL

https://maps.google.com/?ll=latitude,longitude

Example: maps.google.com/?ll=38.882147,-76.99017

UPDATE

As of year 2017, Google now has an official way to create cross-platform Google Maps URLs:

https://developers.google.com/maps/documentation/urls/guide

You can use links like

https://www.google.com/maps/search/?api=1&query=1200%20Pennsylvania%20Ave%20SE%2C%20Washington%2C%20District%20of%20Columbia%2C%2020003 

I'm able to run an SQL query by piping it to SQL*Plus:

@echo select count(*) from table; | sqlplus username/password@database

Give

@echo execute some_procedure | sqlplus username/password@databasename

a try.

instead of these custom error messages we can specify the type of the text field.

Ex: set type of the field in to type = 'email'

then plugin will identify the field and validate correctly.

I can give you an example which results with the same problem, but it may not give you an answer to your question. (Additionally, in this example, I'm using my Maven 3 knowledge, which may not apply for Maven 2.)

In a multi-module maven project (contains modules A and B, where B depends on A), you can add also a test dependency on A from B.

This dependency may look as follows:

<dependency>
     <groupId>com.foo</groupId>
     <artifactId>A</artifactId>
     <type>test-jar</type> <!-- I'm not sure if there is such a thing in Maven 2, but there is definitely a way to achieve such dependency in Maven 2. -->
     <scope>test</scope>
</dependency>

(for more information refer to https://maven.apache.org/guides/mini/guide-attached-tests.html)
Note that the project A produces secondary artifact with a classifier tests where the test classes and test resources are located.

If you build your project with -Dmaven.test.skip=true, you will get a dependency resolution error as long as the test artifact wasn't found in your local repo or external repositories. The reason is that the tests classes were neither compiled nor the tests artifact was produced.
However, if you run your build with -DskipTests your tests artifact will be produced (though the tests won't run) and the dependency will be resolved.

Attach your variable to the req object, not res.

Instead of

res.somevariable = variable1;

Have:

req.somevariable = variable1;

As others have pointed out, res.locals is the recommended way of passing data through middleware.

I do something similar in one of my blog postings. A simple C++ example is shown.

The aim was to use the open source cvBlobsLib library for the detection of spot samples printed to microarray slides, but the images have to be converted from colour -> grayscale -> black + white as you mentioned, in order to achieve this.

For me even with [formGroup] the error was popping up "Cannot find control with name:''".
It got fixed when I added ngModel Value to the input box along with formControlName="fileName"

  <form class="upload-form" [formGroup]="UploadForm">
  <div class="row">
    <div class="form-group col-sm-6">
      <label for="fileName">File Name</label>
      <!-- *** *** *** Adding [(ngModel)]="FileName" fixed the issue-->
      <input type="text" class="form-control" id="fileName" [(ngModel)]="FileName"
        placeholder="Enter file name" formControlName="fileName"> 
    </div>
    <div class="form-group col-sm-6">
      <label for="selectedType">File Type</label>
      <select class="form-control" formControlName="selectedType" id="selectedType" 
        (change)="TypeChanged(selectedType)" name="selectedType" disabled="true">
        <option>Type 1</option>
        <option>Type 2</option>
      </select>
    </div>
  </div>
  <div class="form-group">
    <label for="fileUploader">Select {{selectedType}} file</label>
    <input type="file" class="form-control-file" id="fileUploader" (change)="onFileSelected($event)">
  </div>
  <div class="w-80 text-right mt-3">
    <button class="btn btn-primary mb-2 search-button cancel-button" (click)="cancelUpload()">Cancel</button>
    <button class="btn btn-primary mb-2 search-button" (click)="uploadFrmwrFile()">Upload</button>
  </div>
 </form>

And in the controller

ngOnInit() {
this.UploadForm= new FormGroup({
  fileName: new FormControl({value: this.FileName}),
  selectedType: new FormControl({value: this.selectedType, disabled: true}, Validators.required),
  frmwareFile: new FormControl({value: ['']})
});
}

If you want to re-filter the json data you can use following method. Given example is getting all document data from couchdb.

{
    Gson gson = new Gson();
    String resultJson = restTemplate.getForObject(url+"_all_docs?include_docs=true", String.class);
    JSONObject object =  (JSONObject) new JSONParser().parse(resultJson);
    JSONArray rowdata = (JSONArray) object.get("rows");   
    List<Object>list=new ArrayList<Object>();   
    for(int i=0;i<rowdata.size();i++) {
        JSONObject index = (JSONObject) rowdata.get(i);
        JSONObject data = (JSONObject) index.get("doc");
        list.add(data);      
    }
    // convert your list to json
    String devicelist = gson.toJson(list);
    return devicelist;
}

To answer your question, Hibernate is an implementation of the JPA standard. Hibernate has its own quirks of operation, but as per the Hibernate docs

By default, Hibernate uses lazy select fetching for collections and lazy proxy fetching for single-valued associations. These defaults make sense for most associations in the majority of applications.

So Hibernate will always load any object using a lazy fetching strategy, no matter what type of relationship you have declared. It will use a lazy proxy (which should be uninitialized but not null) for a single object in a one-to-one or many-to-one relationship, and a null collection that it will hydrate with values when you attempt to access it.

It should be understood that Hibernate will only attempt to fill these objects with values when you attempt to access the object, unless you specify fetchType.EAGER.

As per latest api docs:

$(document).ready(function() {
    $('#example').dataTable({
        "order": []
    });
});

More Info

With async you just do:

await Task.Run(() => do some stuff);
// continue doing stuff on the same context as before.
// while it is the default it is nice to be explicit about it with:
await Task.Run(() => do some stuff).ConfigureAwait(true);

However:

await Task.Run(() => do some stuff).ConfigureAwait(false);
// continue doing stuff on the same thread as the task finished on.

            return false
        }
    }
}

//and use like so:
if "16465551212".validPhoneNumber {
    print("valid phone number")
}

Please "include" both Controller and the module(s) where the controller and the functions called in the Controller are.

module(theModule);

$('#datepicker-dep').datepicker({
    minDate: 0
});

minDate:0 works for me.

From here:

"You can also refer to the properties of the data object via that object, instead of accessing them as variables." Meaning that for OP's case this will work (with a significantly smaller change than other possible solutions):

<% if (obj.date) { %><span class="date"><%= date %></span><% }  %>

According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.0</version>
</dependency>

Jakarta EE 8 update (Mar 2020)

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>2.3.3</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.3</version>
  <scope>runtime</scope>
</dependency>

Jakarta EE 9 update (Nov 2020)

Use latest release of Eclipse Implementation of JAXB 3.0.0:

• Jakarta EE9 API jakarta.xml.bind-api
• compatible implementation jaxb-impl

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>3.0.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>3.0.0</version>
  <scope>runtime</scope>
</dependency>

Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:

javax.xml.bind -> jakarta.xml.bind

An alternative is to call the pip module by using python2.7, as below:

python2.7 -m pip <commands>

For example, you could run python2.7 -m pip install <package> to install your favorite python modules. Here is a reference: https://stackoverflow.com/a/50017310/4256346.

In case the pip module has not yet been installed for this version of python, you can run the following:

python2.7 -m ensurepip

Running this command will "bootstrap the pip installer". Note that running this may require administrative privileges (i.e. sudo). Here is a reference: https://docs.python.org/2.7/library/ensurepip.html and another reference https://stackoverflow.com/a/46631019/4256346.

I found out that it also happens if you uninstalled some packages from your react-native project and there is still packages in your build gradle dependencies in the bottom of page like:

{
 project(':react-native-sound-player')
}

Base/Revise on Pengyang answer

And inspired from permutations-in-javascript

The c# version FunctionalPermutations should be this

static IEnumerable<IEnumerable<T>> FunctionalPermutations<T>(IEnumerable<T> elements, int length)
    {
        if (length < 2) return elements.Select(t => new T[] { t });
        /* Pengyang answser..
          return _recur_(list, length - 1).SelectMany(t => list.Where(e => !t.Contains(e)),(t1, t2) => t1.Concat(new T[] { t2 }));
        */
        return elements.SelectMany((element_i, i) => 
          FunctionalPermutations(elements.Take(i).Concat(elements.Skip(i + 1)), length - 1)
            .Select(sub_ei => new[] { element_i }.Concat(sub_ei)));
    }

In Python 3, urllib2 was replaced by two in-built modules named urllib.request and urllib.error

Adapted from source

So replace this:

import urllib2

With this:

import urllib.request as urllib2

I've used this successfully inside R script:

library("reshape2",lib.loc="/path/to/R-packages/")

useful if for whatever reason libraries are in more than one place.

In cases where I don't care whether the variable is undef or equal to '', I usually summarize it as:

$name = "" unless defined $name;
if($name ne '') {
  # do something with $name
}

In which way do you want it dynamic? If you want the popup to successfully map to the background, you need to create two backgrounds. It requires both the use of element() or -moz-element() and a filter (for Firefox, use a SVG filter like filter: url(#svgBlur) since Firefox does not support -moz-filter: blur() as yet?). It only works in Firefox at the time of writing.

See demo here.

I still need to create a simple demo to show how it is done. You're welcome to view the source.

Here's how you can mock your FileConnection

Mock<IFileConnection> fileConnection = new Mock<IFileConnection>(
                                                           MockBehavior.Strict);
fileConnection.Setup(item => item.Get(It.IsAny<string>,It.IsAny<string>))
              .Throws(new IOException());

Then instantiate your Transfer class and use the mock in your method call

Transfer transfer = new Transfer();
transfer.GetFile(fileConnection.Object, someRemoteFilename, someLocalFileName);

Update:

First of all you have to mock your dependencies only, not the class you are testing(Transfer class in this case). Stating those dependencies in your constructor make it easy to see what services your class needs to work. It also makes it possible to replace them with fakes when you are writing your unit tests. At the moment it's impossible to replace those properties with fakes.

Since you are setting those properties using another dependency, I would write it like this:

public class Transfer
{
    public Transfer(IInternalConfig internalConfig)
    {
        source = internalConfig.GetFileConnection("source");
        destination = internalConfig.GetFileConnection("destination");
    }

    //you should consider making these private or protected fields
    public virtual IFileConnection source { get; set; }
    public virtual IFileConnection destination { get; set; }

    public virtual void GetFile(IFileConnection connection, 
        string remoteFilename, string localFilename)
    {
        connection.Get(remoteFilename, localFilename);
    }

    public virtual void PutFile(IFileConnection connection, 
        string localFilename, string remoteFilename)
    {
        connection.Get(remoteFilename, localFilename);
    }

    public virtual void TransferFiles(string sourceName, string destName)
    {
        var tempName = Path.GetTempFileName();
        GetFile(source, sourceName, tempName);
        PutFile(destination, tempName, destName);
    }
}

This way you can mock internalConfig and make it return IFileConnection mocks that does what you want.

As mentioned earlier, you can use the grid system to layout your inputs and labels anyway that you want. The trick is to remember that you can use rows within your columns to break them into twelfths as well.

The example below is one possible way to accomplish your goal and will put the two text boxes near Label3 on the same line when the screen is small or larger.

This can be done using the numeric_limits in C++:

These are the methods you probably want to look at:

infinity()  T   Representation of positive infinity, if available.
quiet_NaN() T   Representation of quiet (non-signaling) "Not-a-Number", if available.
signaling_NaN() T   Representation of signaling "Not-a-Number", if available.

image view add as a sub view to the tableview cell

UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(20, 5, 90, 70)];
imgView.backgroundColor=[UIColor clearColor];
[imgView.layer setCornerRadius:8.0f];
[imgView.layer setMasksToBounds:YES];
[imgView setImage:[UIImage imageWithData: imageData]];
[cell.contentView addSubview:imgView];

Use

public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
    return shouldOverrideUrlLoading(view, request.getUrl().toString());
}

This post already has a checked answer, but the answer doesn't filter for null values. The correct answer should prevent null values by using the Object::nonNull function as a predicate.

BigDecimal result = invoiceList.stream()
    .map(Invoice::total)
    .filter(Objects::nonNull)
    .filter(i -> (i.getUnit_price() != null) && (i.getQuantity != null))
    .reduce(BigDecimal.ZERO, BigDecimal::add);

This prevents null values from attempting to be summed as we reduce.

If none of the above solutions work for you (they did not for me) here is what worked on my server:

RewriteCond %{HTTPS} =on
RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1 [L,R=301]

How wide is the text column?

With a GROUP BY there's not much you can do to avoid a data scan (at least an index scan).

I'd recommend:

1. If possible, changing the schema to remove duplication of text data. This way the count will happen on a narrow foreign key field in the 'many' table.

2. Alternatively, creating a generated column with a HASH of the text, then GROUP BY the hash column. Again, this is to decrease the workload (scan through a narrow column index)

Edit:

Your original question did not quite match your edit. I'm not sure if you're aware that the COUNT, when used with a GROUP BY, will return the count of items per group and not the count of items in the entire table.

You can try this also...

button {
  background: none;
  border: 0;
  box-sizing: border-box;
  margin: 1em;
  padding: 1em 2em;
  box-shadow: inset 0 0 0 2px #f45e61;
  color: #f45e61;
  font-size: inherit;
  font-weight: 700;
  vertical-align: middle;
  position: relative;
}
button::before, button::after {
  box-sizing: inherit;
  content: '';
  position: absolute;
  width: 100%;
  height: 100%;
}

.draw {
  -webkit-transition: color 0.25s;
  transition: color 0.25s;
}
.draw::before, .draw::after {
  border: 2px solid transparent;
  width: 0;
  height: 0;
}
.draw::before {
  top: 0;
  left: 0;
}
.draw::after {
  bottom: 0;
  right: 0;
}
.draw:hover {
  color: #60daaa;
}
.draw:hover::before, .draw:hover::after {
  width: 100%;
  height: 100%;
}
.draw:hover::before {
  border-top-color: #60daaa;
  border-right-color: #60daaa;
  -webkit-transition: width 0.25s ease-out, height 0.25s ease-out 0.25s;
  transition: width 0.25s ease-out, height 0.25s ease-out 0.25s;
}
.draw:hover::after {
  border-bottom-color: #60daaa;
  border-left-color: #60daaa;
  -webkit-transition: border-color 0s ease-out 0.5s, width 0.25s ease-out 0.5s, height 0.25s ease-out 0.75s;
  transition: border-color 0s ease-out 0.5s, width 0.25s ease-out 0.5s, height 0.25s ease-out 0.75s;
}

<section class="buttons">
  <button class="draw">Draw</button>
</section>

You can use color code also.

 const marker: Marker = this.map.addMarkerSync({
    icon: '#008000',
    animation: 'DROP',
    position: {lat: 39.0492127, lng: -111.1435662},
    map: this.map,
 });

library is an object, not an array. You push things onto arrays. Unlike PHP, Javascript makes a distinction.

Your code tries to make a string that looks like the source code for a key-value pair, and then "push" it onto the object. That's not even close to how it works.

What you want to do is add a new key-value pair to the object, where the key is the title and the value is another object. That looks like this:

library[title] = {"foregrounds" : foregrounds, "backgrounds" : backgrounds};

"JSON object" is a vague term. You must be careful to distinguish between an actual object in memory in your program, and a fragment of text that is in JSON format.

Different types to check the values exists

d = {"key1":"value1", "key2":"value2"}
"value10" in d.values() 
>> False

What if list of values

test = {'key1': ['value4', 'value5', 'value6'], 'key2': ['value9'], 'key3': ['value6']}
"value4" in [x for v in test.values() for x in v]
>>True

What if list of values with string values

test = {'key1': ['value4', 'value5', 'value6'], 'key2': ['value9'], 'key3': ['value6'], 'key5':'value10'}
values = test.values()
"value10" in [x for v in test.values() for x in v] or 'value10' in values
>>True

Both these will give you the first child node:

console.log(parentElement.firstChild); // or
console.log(parentElement.childNodes[0]);

If you need the first child that is an element node then use:

console.log(parentElement.children[0]);

Edit

Ah, I see your problem now; parentElement is an array.

If you know that getElementsByClassName will only return one result, which it seems you do, you should use [0] to dearray (yes, I made that word up) the element:

var parentElement = document.getElementsByClassName("uniqueClassName")[0];

One way you could get round it is by having delegates on the view model to handle printing out special rendering like this. I've done this for a paging class, I expose a public property on the model Func<int, string> RenderUrl to deal with it.

So define how the custom bit will be written:

Model.Paging.RenderUrl = (page) => { return string.Concat(@"/foo/", page); };

Output the view for the Paging class:

@Html.DisplayFor(m => m.Paging)

...and for the actual Paging view:

@model Paging
@if (Model.Pages > 1)
{
    <ul class="paging">
    @for (int page = 1; page <= Model.Pages; page++)
    {
        <li><a href="@Model.RenderUrl(page)">@page</a></li>
    }
    </ul>
}

It could be seen as over-complicating matters but I use these pagers everywhere and couldn't stand seeing the same boilerplate code to get them rendered.

str_replace('"', "", $string);
str_replace("'", "", $string);

I assume you mean quotation marks?

Otherwise, go for some regex, this will work for html quotes for example:

preg_replace("/<!--.*?-->/", "", $string);

C-style quotes:

preg_replace("/\/\/.*?\n/", "\n", $string);

CSS-style quotes:

preg_replace("/\/*.*?\*\//", "", $string);

bash-style quotes:

preg-replace("/#.*?\n/", "\n", $string);

Etc etc...

Command mvnw uses Maven that is by default downloaded to ~/.m2/wrapper on the first use.

URL with Maven is specified in each project at .mvn/wrapper/maven-wrapper.properties:

distributionUrl=https://repo1.maven.org/maven2/org/apache/maven/apache-maven/3.3.9/apache-maven-3.3.9-bin.zip

To update or change Maven version invoke the following (remember about --non-recursive for multi-module projects):

./mvnw io.takari:maven:wrapper -Dmaven=3.3.9 

or just modify .mvn/wrapper/maven-wrapper.properties manually.

To generate wrapper from scratch using Maven (you need to have it already in PATH run:

mvn io.takari:maven:wrapper -Dmaven=3.3.9 

select 'ScriptName', scriptName from table
union all
select 'ScriptCode', scriptCode from table
union all
select 'Price', price from table

What about:

list1 = [3,2,4,1, 1]
list2 = ['three', 'two', 'four', 'one', 'one2']

sortedRes = sorted(zip(list1, list2), key=lambda x: x[0]) # use 0 or 1 depending on what you want to sort
>>> [(1, 'one'), (1, 'one2'), (2, 'two'), (3, 'three'), (4, 'four')]

Generally speaking, fixed section should be set with width, height and top, bottom properties, otherwise it won't recognise its size and position.

If the used box is direct child for body and has neighbours, then it makes sense to check z-index and top, left properties, since they could overlap each other, which might affect your mouse hover while scrolling the content.

Here is the solution for a content box (a direct child of body tag) which is commonly used along with mobile navigation.

.fixed-content {
    position: fixed;
    top: 0;
    bottom:0;

    width: 100vw; /* viewport width */
    height: 100vh; /* viewport height */
    overflow-y: scroll;
    overflow-x: hidden;
}

Hope it helps anybody. Thank you!

@Presto Thanks! Yours worked perfectly for me, but I came up with a simpler version to save changing everything around.

Add a <span> tag around the desired link text, specifying class within. (e.g. home tag)

<nav id="top-menu">
    <ul>
        <li> <a href="home.html"><span class="currentLink">Home</span></a> </li>
        <li> <a href="about.html">About</a> </li>
        <li> <a href="cv.html">CV</a> </li>
        <li> <a href="photos.html">Photos</a> </li>
        <li> <a href="archive.html">Archive</a> </li>
        <li> <a href="contact.html">Contact</a></li>
    </ul>
</nav>

Then edit your CSS accordingly:

.currentLink {
    color:#baada7;
}

Two ways come to mind:

• Using a command-line tool like the popular ffmpeg, however you will almost always need an own server (or a very nice server administrator / hosting company) to get that

• Using the "screenshoot" plugin for the LongTail Video player that allows the creation of manual screenshots that are then sent to a server-side script.

There's another reason unserialize() failed because you improperly put serialized data into the database see Official Explanation here. Since serialize() returns binary data and php variables don't care encoding methods, so that putting it into TEXT, VARCHAR() will cause this error.

Solution: store serialized data into BLOB in your table.

It is creating a folder with multiple files, because each partition is saved individually. If you need a single output file (still in a folder) you can repartition (preferred if upstream data is large, but requires a shuffle):

df
   .repartition(1)
   .write.format("com.databricks.spark.csv")
   .option("header", "true")
   .save("mydata.csv")

or coalesce:

df
   .coalesce(1)
   .write.format("com.databricks.spark.csv")
   .option("header", "true")
   .save("mydata.csv")

data frame before saving:

All data will be written to mydata.csv/part-00000. Before you use this option be sure you understand what is going on and what is the cost of transferring all data to a single worker. If you use distributed file system with replication, data will be transfered multiple times - first fetched to a single worker and subsequently distributed over storage nodes.

Alternatively you can leave your code as it is and use general purpose tools like cat or HDFS getmerge to simply merge all the parts afterwards.

This works and shows more than 255 characters in the message box.

Sub TestStrLength()
    Dim s As String
    Dim i As Integer

    s = ""
    For i = 1 To 500
        s = s & "1234567890"
    Next i

    MsgBox s
End Sub

The message box truncates the string to 1023 characters, but the string itself can be very large.

I would also recommend that instead of using fixed variables names with numbers (e.g. Var1, Var2, Var3, ... Var255) that you use an array. This is much shorter declaration and easier to use - loops.

Here's an example:

Sub StrArray()
Dim var(256) As Integer
Dim i As Integer
Dim s As String

For i = 1 To 256
    var(i) = i
Next i

s = "Tims_pet_Robot"
For i = 1 To 256
    s = s & " """ & var(i) & """"
Next i

    SecondSub (s)
End Sub

Sub SecondSub(s As String)
    MsgBox "String length = " & Len(s)
End Sub

Updated this to show that a string can be longer than 255 characters and used in a subroutine/function as a parameter that way. This shows that the string length is 1443 characters. The actual limit in VBA is 2GB per string.

Perhaps there is instead a problem with the API that you are using and that has a limit to the string (such as a fixed length string). The issue is not with VBA itself.

Ok, I see the problem is specifically with the Application.OnTime method itself. It is behaving like Excel functions in that they only accept strings that are up to 255 characters in length. VBA procedures and functions though do not have this limit as I have shown. Perhaps then this limit is imposed for any built-in Excel object method.

Update:
changed ...longer than 256 characters... to ...longer than 255 characters...

Another way to avoid the error is to use the cast like this:

let secondValue: string = (<any>someObject)[key]; (Note the parenthesis)

The only problem is that this isn't type-safe anymore, as you are casting to any. But you can always cast back to the correct type.

ps: I'm using typescript 1.7, not sure about previous versions.

Not all controls that can be included in a page must be run at the server. For example:

<INPUT type="submit" runat=server />

This is essentially the same as:

<asp:Button runat=server />

Remove the runat=server tag from the first one and you have a standard HTML button that runs in the browser. There are reasons for and against running a particular control at the server, and there is no way for ASP.NET to "assume" what you want based on the HTML markup you include. It might be possible to "infer" the runat=server for the <asp:XXX /> family of controls, but my guess is that Microsoft would consider that a hack to the markup syntax and ASP.NET engine.

The answer depends on the presence of other shapes, level of noise if any and invariance you want to provide for (e.g. rotation, scaling, etc). These requirements will define not only the algorithm but also required pre-procesing stages to extract features.

Template matching that was suggested above works well when shapes aren't rotated or scaled and when there are no similar shapes around; in other words, it finds a best translation in the image where template is located:

double minVal, maxVal;
Point minLoc, maxLoc;
Mat image, template, result; // template is your shape
matchTemplate(image, template, result, CV_TM_CCOEFF_NORMED);
minMaxLoc(result, &minVal, &maxVal, &minLoc, &maxLoc); // maxLoc is answer

Geometric hashing is a good method to get invariance in terms of rotation and scaling; this method would require extraction of some contour points.

Generalized Hough transform can take care of invariance, noise and would have minimal pre-processing but it is a bit harder to implement than other methods. OpenCV has such transforms for lines and circles.

In the case when number of shapes is limited calculating moments or counting convex hull vertices may be the easiest solution: openCV structural analysis

For tasks of this type I usually use Crawller4j + Jsoup.

With crawler4j I download the pages from a domain, you can specify which ULR with a regular expression.

With jsoup, I "parsed" the html data you have searched for and downloaded with crawler4j.

Normally you can also download data with jsoup, but Crawler4J makes it easier to find links. Another advantage of using crawler4j is that it is multithreaded and you can configure the number of concurrent threads

I've used Beej's Guide to Network Programming in the past. It's in C, not C++, but the examples are good. Go directly to section 6 for the simple client and server example programs.

Starting June 24th, 2014, you can try cancel a PR easily (See "Reverting a pull request") with:

Introducing the Revert Button

you can easily revert a pull request on GitHub by clicking Revert:

You'll be prompted to create a new pull request with the reverted changes:

It remains to be tested though if that revert uses -m or not (for reverting merges as well)

But Adil H Raza adds in the comments (Dec. 2019):

That is the expected behavior, it created a new branch and you can create a PR from this new branch to your master.
This way in the future you can un-revert the revert if need be, it is safest option and not directly changing your master.

Warning: Korayem points out in the comments that:

After a revert, let's say you did some further changes on Git branch and created a new PR from same source/destination branch.
You will find the PR showing only new changes, but nothing of what was there before reverting.

Korayem refers us to "Github: Changes ignored after revert (git cherry-pick, git rebase)" for more.

The code won't work without an icon. So, add the setSmallIcon call to the builder chain like this for it to work:

.setSmallIcon(R.drawable.icon)

Android Oreo (8.0) and above

Android 8 introduced a new requirement of setting the channelId property by using a NotificationChannel.

private NotificationManager mNotificationManager;

NotificationCompat.Builder mBuilder =
    new NotificationCompat.Builder(mContext.getApplicationContext(), "notify_001");
Intent ii = new Intent(mContext.getApplicationContext(), RootActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(mContext, 0, ii, 0);

NotificationCompat.BigTextStyle bigText = new NotificationCompat.BigTextStyle();
bigText.bigText(verseurl);
bigText.setBigContentTitle("Today's Bible Verse");
bigText.setSummaryText("Text in detail");

mBuilder.setContentIntent(pendingIntent);
mBuilder.setSmallIcon(R.mipmap.ic_launcher_round);
mBuilder.setContentTitle("Your Title");
mBuilder.setContentText("Your text");
mBuilder.setPriority(Notification.PRIORITY_MAX);
mBuilder.setStyle(bigText);

mNotificationManager =
    (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);

// === Removed some obsoletes
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
{
    String channelId = "Your_channel_id";
    NotificationChannel channel = new NotificationChannel(
                                        channelId,
                                        "Channel human readable title",
                                        NotificationManager.IMPORTANCE_HIGH);
   mNotificationManager.createNotificationChannel(channel);
  mBuilder.setChannelId(channelId);
}

mNotificationManager.notify(0, mBuilder.build());

If your device is running Android v4 or above, you can pull app data, including it's database, without root by using adb backup command, then extract the backup file and access the sqlite database.

First backup app data to your PC via USB cable with the following command, replace app.package.name with the actual package name of the application.

adb backup -f ~/data.ab -noapk app.package.name

This will prompt you to "unlock your device and confirm the backup operation". Do not provide a password for backup encryption, so you can extract it later. Click on the "Back up my data" button on your device. The screen will display the name of the package you're backing up, then close by itself upon successful completion.

The resulting data.ab file in your home folder contains application data in android backup format. To extract it use the following command:

dd if=data.ab bs=1 skip=24 | openssl zlib -d | tar -xvf -

If the above ended with openssl:Error: 'zlib' is an invalid command. error, try the below.

dd if=data.ab bs=1 skip=24 | python -c "import zlib,sys;sys.stdout.write(zlib.decompress(sys.stdin.read()))" | tar -xvf -

The result is the apps/app.package.name/ folder containing application data, including sqlite database.

For more details you can check the original blog post.

You can do this with the aeimageresize jquery plugin.

https://plugins.jquery.com/ae.image.resize

$(function() {
    $( ".resizeme" ).aeImageResize({ height: 250, width: 250 });
});

The following complete example will read an existing server.xml file from the current directory, append a new Server and re-write the file to server.xml. It does not work without an existing .xml file, so you will need to modify the code to handle that case.

import java.util.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.dom.*;
import org.w3c.dom.*;
import javax.xml.parsers.*;

public class AddXmlNode {
    public static void main(String[] args) throws Exception {

        DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
        Document document = documentBuilder.parse("server.xml");
        Element root = document.getDocumentElement();

        Collection<Server> servers = new ArrayList<Server>();
        servers.add(new Server());

        for (Server server : servers) {
            // server elements
            Element newServer = document.createElement("server");

            Element name = document.createElement("name");
            name.appendChild(document.createTextNode(server.getName()));
            newServer.appendChild(name);

            Element port = document.createElement("port");
            port.appendChild(document.createTextNode(Integer.toString(server.getPort())));
            newServer.appendChild(port);

            root.appendChild(newServer);
        }

        DOMSource source = new DOMSource(document);

        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        StreamResult result = new StreamResult("server.xml");
        transformer.transform(source, result);
    }

    public static class Server {
        public String getName() { return "foo"; }
        public Integer getPort() { return 12345; }
    }
}

Example server.xml file:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Servers>
  <server>
    <name>something</name>
    <port>port</port>
  </server>
</Servers>

The main change to your code is not creating a new "root" element. The above example just uses the current root node from the existing server.xml and then just appends a new Server element and re-writes the file.

var variables still have a type - and the compiler error message says this type must be established during the declaration.

The specific request (assigning an initial null value) can be done, but I don't recommend it. It doesn't provide an advantage here (as the type must still be specified) and it could be viewed as making the code less readable:

var x = (String)null;

Which is still "type inferred" and equivalent to:

String x = null;

The compiler will not accept var x = null because it doesn't associate the null with any type - not even Object. Using the above approach, var x = (Object)null would "work" although it is of questionable usefulness.

Generally, when I can't use var's type inference correctly then

1. I am at a place where it's best to declare the variable explicitly; or
2. I should rewrite the code such that a valid value (with an established type) is assigned during the declaration.

The second approach can be done by moving code into methods or functions.

For Eclipse IDE the Coffee-Bytes plugin can do it, download link is here.

EDIT:

Latest information about Coffee-Bytes is here.

I did not see any mention of it in the other answers, so here are my 2 Canadian cents:

On the "using namespace" topic, a useful statement is the namespace alias, allowing you to "rename" a namespace, normally to give it a shorter name. For example, instead of:

Some::Impossibly::Annoyingly::Long:Name::For::Namespace::Finally::TheClassName foo;
Some::Impossibly::Annoyingly::Long:Name::For::Namespace::Finally::AnotherClassName bar;

you can write:

namespace Shorter = Some::Impossibly::Annoyingly::Long:Name::For::Namespace::Finally;
Shorter::TheClassName foo;
Shorter::AnotherClassName bar;

ebdiv is set style="display:none;"

it is works show & hide

$(document).ready(function(){
    $("#eb").click(function(){
        $("#ebdiv").toggle();
    });

});

Your 0xED 0x6E 0x2C 0x20 bytes correspond to "ín, " in ISO-8859-1, so it looks like your content is in ISO-8859-1, not UTF-8. Tell your data provider about it and ask them to fix it, because if it doesn't work for you it probably doesn't work for other people either.

Now there are a few ways to work it around, which you should only use if you cannot load the XML normally. One of them would be to use utf8_encode(). The downside is that if that XML contains both valid UTF-8 and some ISO-8859-1 then the result will contain mojibake. Or you can try to convert the string from UTF-8 to UTF-8 using iconv() or mbstring, and hope they'll fix it for you. (they won't, but you can at least ignore the invalid characters so you can load your XML)

Or you can take the long, long road and validate/fix the sequences by yourself. That will take you a while depending on how familiar you are with UTF-8. Perhaps there are libraries out there that would do that, although I don't know any.

Either way, notify your data provider that they're sending invalid data so that they can fix it.

Here's a partial fix. It will definitely not fix everything, but will fix some of it. Hopefully enough for you to get by until your provider fix their stuff.

function fix_latin1_mangled_with_utf8_maybe_hopefully_most_of_the_time($str)
{
    return preg_replace_callback('#[\\xA1-\\xFF](?![\\x80-\\xBF]{2,})#', 'utf8_encode_callback', $str);
}

function utf8_encode_callback($m)
{
    return utf8_encode($m[0]);
}

This works great

.create:before{
    content: "";
    display: block;
    background: url('somewhere.jpg') no-repeat;
    width: 25px;
    height: 25px;
    float: left;
}

malloc for single chars or integers and calloc for dynamic arrays. ie pointer = ((int *)malloc(sizeof(int)) == NULL), you can do arithmetic within the brackets of malloc but you shouldnt because you should use calloc which has the definition of void calloc(count, size)which means how many items you want to store ie count and size of data ie int , char etc.

The most common way to do this is something along these lines:

ul {_x000D_
  list-style: none;_x000D_
  padding: 0;_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
li {_x000D_
  padding-left: 1em; _x000D_
  text-indent: -.7em;_x000D_
}_x000D_
_x000D_
li::before {_x000D_
  content: "• ";_x000D_
  color: red; /* or whatever color you prefer */_x000D_
}

<ul>_x000D_
  <li>Foo</li>_x000D_
  <li>Bar</li>_x000D_

For some components, it is easier to use inline styles. Also, I find it easier and more concise (as I'm using Javascript and not CSS) to animate component styles.

For stand-alone components, I use the 'Spread Operator' or the '...'. For me, it's clear, beautiful, and works in a tight space. Here is a little loading animation I made to show it's benefits:

<div style={{...this.styles.container, ...this.state.opacity}}>
    <div style={{...this.state.colors[0], ...this.styles.block}}/>
    <div style={{...this.state.colors[1], ...this.styles.block}}/>
    <div style={{...this.state.colors[2], ...this.styles.block}}/>
    <div style={{...this.state.colors[7], ...this.styles.block}}/>
    <div style={{...this.styles.block}}/>
    <div style={{...this.state.colors[3], ...this.styles.block}}/>
    <div style={{...this.state.colors[6], ...this.styles.block}}/>
    <div style={{...this.state.colors[5], ...this.styles.block}}/>
    <div style={{...this.state.colors[4], ...this.styles.block}}/>
  </div>

    this.styles = {
  container: {
    'display': 'flex',
    'flexDirection': 'row',
    'justifyContent': 'center',
    'alignItems': 'center',
    'flexWrap': 'wrap',
    'width': 21,
    'height': 21,
    'borderRadius': '50%'
  },
  block: {
    'width': 7,
    'height': 7,
    'borderRadius': '50%',
  }
}
this.state = {
  colors: [
    { backgroundColor: 'red'},
    { backgroundColor: 'blue'},
    { backgroundColor: 'yellow'},
    { backgroundColor: 'green'},
    { backgroundColor: 'white'},
    { backgroundColor: 'white'},
    { backgroundColor: 'white'},
    { backgroundColor: 'white'},
    { backgroundColor: 'white'},
  ],
  opacity: {
    'opacity': 0
  }
}

EDIT NOVEMBER 2019

Working in the industry (A Fortune 500 company), I am NOT allowed to make any inline styling. In our team, we've decided that inline style are unreadable and not maintainable. And, after having seen first hand how inline styles make supporting an application completely intolerable, I'd have to agree. I completely discourage inline styles.

The only solution that worked for me and $.each was definitely causing the error. so i used for loop and it's not throwing error anymore.

Example code

     $.ajax({
            type: 'GET',
            url: 'https://example.com/api',
            data: { get_param: 'value' },
            success: function (data) {
                for (var i = 0; i < data.length; ++i) {
                    console.log(data[i].NameGerman);
                }
            }
        });

you can do update the User path as inside _JAVA_OPTIONS : -Xmx512M Path : C:\Program Files (x86)\Java\jdk1.8.0_231\bin;C:\Program Files(x86)\Java\jdk1.8.0_231\jre\bin for now it is working / /

package com.test;

public class TEst {

    public static void main(String[] args) {

        List<Integer> ls=new ArrayList<>();
        ls.add(1);
        ls.add(2);
        List<Integer> ls1=new ArrayList<>();
        ls1.add(3);
        ls1.add(4);
        List<List<Integer>> ls2=new ArrayList<>();
        ls2.add(ls);
        ls2.add(ls1);

        List<List<List<Integer>>> ls3=new ArrayList<>();
        ls3.add(ls2);


        m1(ls3);
    }

    private static void m1(List ls3) {
        for(Object ls4:ls3)
        {
             if(ls4 instanceof List)    
             {
                m1((List)ls4);
             }else {
                 System.out.print(ls4);
             }

        }
    }

}

You can't modify a String in Java. They are immutable. All you can do is create a new string that is substring of the old string, minus the last character.

In some cases a StringBuffer might help you instead.

That would work depending on what client.get does when passed undefined as its first parameter.

Something like this would be safer:

app.get('/:key?', function(req, res, next) {
    var key = req.params.key;
    if (!key) {
        next();
        return;
    }
    client.get(key, function(err, reply) {
        if(client.get(reply)) {
            res.redirect(reply);
        }
        else {
            res.render('index', {
                link: null
            });
        }
    });
});

There's no problem in calling next() inside the callback.

According to this, handlers are invoked in the order that they are added, so as long as your next route is app.get('/', ...) it will be called if there is no key.

I second the opensta suggestion. I would just add that it allows you to do things to monitor the server you're testing using SMTP. We keep track of processor load, memory used, byes sent, etc. The only downside is that if you find something boken and want to do a fix it relies on several open-source libraries that are no longer kept up, so getting a compiling version of the source is more tricky than with most OSS.

Change statement to

  DBCC CHECKIDENT('TableName', RESEED, 1)

This will start from 2 (or 1 when you recreate table), but it will never be 0.

You can use echo and prefix "\033", simple:

Artisan::command('mycommand', function () {
   echo "\033======== Start ========\n";
});

And change color text:

if (App::environment() === 'production') {
    echo "\033[0;33m======== WARNING ========\033[0m\n";
}

Here is the answer with some explanation.

st = "Hey, you - what are you doing here!?"

# replace all the non alpha-numeric with space and then join.
new_string = ''.join([x.replace(x, ' ') if not x.isalnum() else x for x in st])
# output of new_string
'Hey  you  what are you doing here  '

# str.split() will remove all the empty string if separator is not provided
new_list = new_string.split()

# output of new_list
['Hey', 'you', 'what', 'are', 'you', 'doing', 'here']

# we can join it to get a complete string without any non alpha-numeric character
' '.join(new_list)
# output
'Hey you what are you doing'

or in one line, we can do like this:

(''.join([x.replace(x, ' ') if not x.isalnum() else x for x in st])).split()

# output
['Hey', 'you', 'what', 'are', 'you', 'doing', 'here']

I have a similar case. I need to install openssl via brew and then use pip to install mitmproxy. I get the same complaint from brew link --force. Following is the solution I reached: (without force link by brew)

LDFLAGS=-L/usr/local/opt/openssl/lib 
CPPFLAGS=-I/usr/local/opt/openssl/include
PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig 
pip install mitmproxy

This does not address the question straightforwardly. I leave the one-liner in case anyone uses pip and requires the openssl lib.

Note: the /usr/local/opt/openssl/lib paths are obtained by brew info openssl

Several years ago I used ga's to optimize asr (automatic speech recognition) grammars for better recognition rates. I started with fairly simple lists of choices (where the ga was testing combinations of possible terms for each slot) and worked my way up to more open and complex grammars. Fitness was determined by measuring separation between terms/sequences under a kind of phonetic distance function. I also experimented with making weakly equivalent variations on a grammar to find one that compiled to a more compact representation (in the end I went with a direct algorithm, and it drastically increased the size of the "language" that we could use in applications).

More recently I have used them as a default hypothesis against which to test the quality of solutions generated from various algorithms. This has largely involved categorization and different kinds of fitting problems (i.e. create a "rule" that explains a set of choices made by reviewers over a dataset(s)).

In arraylist you have a positional order and not a nominal order, so you need to know in advance the element position you need to select or you must loop between elements until you find the element that you need to use. To do this you can use an iterator and an if, for example:

Iterator iter = list.iterator();
while (iter.hasNext())
{
    // if here          
    System.out.println("string " + iter.next());
}

String delimiter = ",";
StringBuilder sb = new StringBuilder();
for (Item i : list) {
    sb.append(delimiter).append(i);
}
sb.toString().replaceFirst(delimiter, "");

Uninstall NPM and install it again.

You haven't mentioned a language, so I'm going to give you some some hints how to do it with the straight Windows API in C.

First, open a connection to the printer with OpenPrinter. Next, start a document with StartDocPrinter having the pDatatype field of the DOC_INFO_1 structure set to "RAW" - this tells the printer driver not to encode anything going to the printer, but to pass it along unchanged. Use StartPagePrinter to indicate the first page, WritePrinter to send the data to the printer, and close it with EndPagePrinter, EndDocPrinter and ClosePrinter when done.

Reassigning the path Xcode is configured with worked for me.

sudo xcode-select -switch /Applications/Xcode.app

You'll then likely be prompted (after trying a command) to agree to the license agreement.

Here's a simple solution: $('td[name=tcol1]')

Key differences between Serializable and Externalizable

1. Marker interface: Serializable is marker interface without any methods. Externalizable interface contains two methods: writeExternal() and readExternal().
2. Serialization process: Default Serialization process will be kicked-in for classes implementing Serializable interface. Programmer defined Serialization process will be kicked-in for classes implementing Externalizable interface.
3. Maintenance: Incompatible changes may break serialisation.
4. Backward Compatibility and Control: If you have to support multiple versions, you can have full control with Externalizable interface. You can support different versions of your object. If you implement Externalizable, it's your responsibility to serialize super class
5. public No-arg constructor: Serializable uses reflection to construct object and does not require no arg constructor. But Externalizable demands public no-arg constructor.

Refer to blog by Hitesh Garg for more details.

Use a SQL function (I'm the author):

• https://github.com/teopost/oracle-scripts/blob/master/fn_gen_inserts.sql

Usage:

select fn_gen_inserts('select * from tablename', 'p_new_owner_name', 'p_new_table_name')
from dual;

where:

p_sql            – dynamic query which will be used to export metadata rows
p_new_owner_name – owner name which will be used for generated INSERT
p_new_table_name – table name which will be used for generated INSERT

p_sql in this sample is 'select * from tablename'

You can find original source code here:

Ashish Kumar's script generates individually usable insert statements instead of a SQL block, but supports fewer datatypes.

I faced similar issue while restarting Nginx and found it to be a cause of SeLinux. Be sure to give a try after either disabling SeLinux or temporarily setting it to Permissive mode using below command:

setenforce 0

I hope it helps :)

You can access component one's method from component two..

componentOne

  ngOnInit() {}

  public testCall(){
    alert("I am here..");    
  }

componentTwo

import { oneComponent } from '../one.component';


@Component({
  providers:[oneComponent ],
  selector: 'app-two',
  templateUrl: ...
}


constructor(private comp: oneComponent ) { }

public callMe(): void {
    this.comp.testCall();
  }

componentTwo html file

<button (click)="callMe()">click</button>

I recently was wondering why my code doesn't work, then I realized, I need to setup the event handlers as soon as the document is loaded, otherwise when browser loads the code line by line, it loads the JavaScript, but it does not yet have the element to assign the event handler to it. with your example, it should be like this:

$(document).ready(function(){
     $("#kat").change(function(){ 
         alert("Hello");
     });
});

This Worked For Me:

background-image: url("/assets/image_complete_path");
background-position: center; /* Center the image */
background-repeat: no-repeat; /* Do not repeat the image */
background-size: cover;
height: 100%;

.help will show you all the options. Do .exit in this case
