For everybody who uses Rider you have to select your project>Right Click>Properties>Configurations Then select Debug and Release and check "Allow unsafe code" for both.

Java does not have pointers like C has, but it does allow you to create new objects on the heap which are "referenced" by variables. The lack of pointers is to stop Java programs from referencing memory locations illegally, and also enables Garbage Collection to be automatically carried out by the Java Virtual Machine.

Can I point out that if you're going to iterate over a collection and use StringBuilder, you may want to check out Apache Commons Lang and StringUtils.join() (in different flavours) ?

Regardless of performance, it'll save you having to create StringBuilders and for loops for what seems like the millionth time.

Linux doesn't have a separate threads per process limit, just a limit on the total number of processes on the system (threads are essentially just processes with a shared address space on Linux) which you can view like this:

cat /proc/sys/kernel/threads-max

The default is the number of memory pages/4. You can increase this like:

echo 100000 > /proc/sys/kernel/threads-max

There is also a limit on the number of processes (and hence threads) that a single user may create, see ulimit/getrlimit for details regarding these limits.

Previous answers were good and correct, but in my opinion, an extra names parameter will make it perfect, and it should be the recommended way, especially when the csv has no headers.

Solution

Use usecols and names parameters

df = pd.read_csv(file_path, usecols=[3,6], names=['colA', 'colB'])

Additional reading

or use header=None to explicitly tells people that the csv has no headers (anyway both lines are identical)

df = pd.read_csv(file_path, usecols=[3,6], names=['colA', 'colB'], header=None)

So that you can retrieve your data by

# with `names` parameter
df['colA']
df['colB'] 

instead of

# without `names` parameter
df[0]
df[1]

Explain

Based on read_csv, when names are passed explicitly, then header will be behaving like None instead of 0, so one can skip header=None when names exist.

Maybe it is sufficient if you wrap a Card around the Widget and play a bit with the elevation prop.

I use this trick to make my ListTile look nicer in Lists.

For your code it could look like this:

return Card(
   elevation: 3, // PLAY WITH THIS VALUE 
   child: Row(
      crossAxisAlignment: CrossAxisAlignment.center,
      children: <Widget>[
         // ... MORE OF YOUR CODE 
      ],
   ),
);

I encounter the error as well,

_mysql_exceptions.ProgrammingError: not all arguments converted during string formatting 

But list args work well.

I use mysqlclient python lib. The lib looks like not to accept tuple args. To pass list args like ['arg1', 'arg2'] will work.

What i have found in nearly all the variations and the regex from the bulk transfer pdf and what is on wikipedia site is this, specifically for the wikipedia regex is, there needs to be a ^ after the first |(vertical bar). I figured this out by testing for AA9A 9AA, because otherwise the format check for A9A 9AA will validate it. For Example checking for EC1D 1BB which should be invalid comes back valid because C1D 1BB is a valid format.

Here is what I've come up with for a good regex:

^([G][I][R] 0[A]{2})|^((([A-Z-[QVX]][0-9]{1,2})|([A-Z-[QVX]][A-HK-Y][0-9]{1,2})|([A-Z-[QVX]][0-9][ABCDEFGHJKPSTUW])|([A-Z-[QVX]][A-HK-Y][0-9][ABEHMNPRVWXY])) [0-9][A-Z-[CIKMOV]]{2})$

If you just want to kill any/all java processes, then all you need is;

killall java

If, however, you want to kill the wskInterface process in particular, then you're most of the way there, you just need to strip out the process id;

PID=`ps -ef | grep wskInterface | awk '{ print $2 }'`
kill -9 $PID

Should do it, there is probably an easier way though...

<div class="button_style">
This is your button value
</div>

.button_style{   
background-color: Transparent;
border: none;             /* Your can add different style/properties of button Here*/
cursor:pointer;    
}

If you are using Joseph's answer which is a great answer, and you run these back to back like this:

dim i = GetRandom(1, 1715)
dim o = GetRandom(1, 1715)

Then the result could come back the same over and over because it processes the call so quickly. This may not have been an issue in '08, but since the processors are much faster today, the function doesn't allow the system clock enough time to change prior to making the second call.

Since the System.Random() function is based on the system clock, we need to allow enough time for it to change prior to the next call. One way of accomplishing this is to pause the current thread for 1 millisecond. See example below:

Public Function GetRandom(ByVal min as Integer, ByVal max as Integer) as Integer
    Static staticRandomGenerator As New System.Random
    max += 1
    Return staticRandomGenerator.Next(If(min > max, max, min), If(min > max, min, max))
End Function

When you want to have cross component interaction, then you need to know what are @Input , @Output , EventEmitter and Subjects.

If the relation between components is parent- child or vice versa we use @input & @output with event emitter..

@output emits an event and you need to emit using event emitter.

If it's not parent child relationship.. then you have to use subjects or through a common service.

You just rebuilt your project

compile fileTree(dir: 'libs', include: ['*.jar'])

Use this:

TimeSpan numberOfDays = new TimeSpan(2, 0, 0, 0, 0);
newDateTime = dateTime.Add(numberOfDays);

After lot of trial and error I found that there is a very easy way to do this that is by creating an interface in adapter class and implementing that in fragment now here comes the twist, I instansiated the view model inside my override function present In the fragment now you can send the data from that function to viemodel and from there anywhere.

I don't know if this method is good coding method but please let me know in comment and if any wants to see the let me know in the comment section I regularly open stackover flow.

Whenever you want to execute an SQL statement that shouldn't return a value or a record set, the ExecuteNonQuery should be used.

So if you want to run an update, delete, or insert statement, you should use the ExecuteNonQuery. ExecuteNonQuery returns the number of rows affected by the statement. This sounds very nice, but whenever you use the SQL Server 2005 IDE or Visual Studio to create a stored procedure it adds a small line that ruins everything.

That line is: SET NOCOUNT ON; This line turns on the NOCOUNT feature of SQL Server, which "Stops the message indicating the number of rows affected by a Transact-SQL statement from being returned as part of the results" and therefore it makes the stored procedure always to return -1 when called from the application (in my case a web application).

In conclusion, remove that line from your stored procedure, and you will now get a value indicating the number of rows affected by the statement.

Happy programming!

Try the following query:

collection.update(
  { _id: id },
  { $pull: { 'contact.phone': { number: '+1786543589455' } } }
);

It will find document with the given _id and remove the phone +1786543589455 from its contact.phone array.

You can use $unset to unset the value in the array (set it to null), but not to remove it completely.

Curl will look for a .curlrc file in your home folder when it starts. You can create (or edit) this file and add this line:

If you are using your property in multi-threaded code then you would be able to see the difference between nonatomic and atomic attributes. Nonatomic is faster than atomic and atomic is thread-safe, not nonatomic.

Vijayendra Tripathi has already given an example for a multi-threaded environment.

new String(byteArray, Charset.defaultCharset())

This will convert a byte array to the default charset in java. It may throw exceptions depending on what you supply with the byteArray.

You could query this registry value to get the SQL version directly:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\90\Tools\ClientSetup\CurrentVersion

Alternatively you can query your instance name and then use sqlcmd with your instance name that you would like:

To see your instance name:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names

Then execute this:

SELECT SERVERPROPERTY('productversion'), SERVERPROPERTY ('productlevel'), SERVERPROPERTY ('edition')

If you are using C++ you can use this code to get the registry information.

If the first segment doesn't start with / it is a relative route. router.navigate needs a relativeTo parameter for relative navigation

Either you make the route absolute:

this.router.navigate(['/foo-content', 'bar-contents', 'baz-content', 'page'], this.params.queryParams)

or you pass relativeTo

this.router.navigate(['../foo-content', 'bar-contents', 'baz-content', 'page'], {queryParams: this.params.queryParams, relativeTo: this.currentActivatedRoute})

As others already suggested, the solution in your case is to sniff multiple events.
Plugins doing this job often listen for the following events:

$input.on('change keydown keypress keyup mousedown click mouseup', handler);

If you think it may fit, you can add focus, blur and other events too.
I suggest not to exceed in the events to listen, as it loads in the browser memory further procedures to execute according to the user's behaviour.

Attention: note that changing the value of an input element with JavaScript (e.g. through the jQuery .val() method) won't fire any of the events above.
(Reference: https://api.jquery.com/change/).

You're talking about template literals.

They allow for both multiline strings and string interpolation.

Multiline strings:

console.log(`foo_x000D_
bar`);_x000D_
// foo_x000D_
// bar

String interpolation:

var foo = 'bar';_x000D_
console.log(`Let's meet at the ${foo}`);_x000D_
// Let's meet at the bar

I would like to correct one issue.

this.css("top", ( $(window).height() - this.height() ) / 2+$(window).scrollTop() + "px");

Above code won't work in cases when this.height (lets assume that user resizes the screen and content is dynamic) and scrollTop() = 0, example:

window.height is 600
this.height is 650

600 - 650 = -50  

-50 / 2 = -25

Now the box is centered -25 offscreen.

The book seems to indicate that those commands yield the same effect:

The simple case is the example you just saw, running git checkout -b [branch] [remotename]/[branch]. If you have Git version 1.6.2 or later, you can also use the --track shorthand:

$ git checkout --track origin/serverfix 
Branch serverfix set up to track remote branch serverfix from origin. 
Switched to a new branch 'serverfix' 

To set up a local branch with a different name than the remote branch, you can easily use the first version with a different local branch name:

$ git checkout -b sf origin/serverfix

That's particularly handy when your bash or oh-my-zsh git completions are able to pull the origin/serverfix name for you - just append --track (or -t) and you are on your way.

    local Length
    test $SourceArrayLength -gt $TargetArrayLength && Length=$SourceArrayLength || Length=$TargetArrayLength


    local Result=""
    local AppendToEnd=""

    IFS=$OLDIFS

    local i

    for ((i = 0; i <= $Length + 1 ; i++ ))
    do
            if [ "${SourceDirectoryArray[$i]}" = "${TargetDirectoryArray[$i]}" ]
            then
                continue    
            elif [ "${SourceDirectoryArray[$i]}" != "" ] && [ "${TargetDirectoryArray[$i]}" != "" ] 
            then

If you're looking to store the information in a table, you need to use an INSERT or an UPDATE statement. It sounds like you need an UPDATE statement:

UPDATE  SomeTable
SET     SomeDateField = GETDATE()
WHERE   SomeID = @SomeID

That's called a closure. It basically seals the code inside the function so that other libraries don't interfere with it. It's similar to creating a namespace in compiled languages.

Example. Suppose I write:

(function() {

    var x = 2;

    // do stuff with x

})();

Now other libraries cannot access the variable x I created to use in my library.

A const to a pointer indicates a "read-only" memory location. Whereas the ones without const are a read-write memory areas. So, you "cannot" convert a const(read-only location) to a normal(read-write) location.

The alternate is to copy the data to a different read-write location and pass this pointer to the required function. You may use strdup() to perform this action.

If the problem allows it, try with EXISTS, since it's optimized to end as soon as a result is found (And don't buffer any response), so, if you are just trying to normalize data for a WHERE clause like this

SELECT FROM SOMETHING S WHERE S.ID IN ( SELECT DISTINCT DCR.SOMETHING_ID FROM DIFF_CARDINALITY_RELATIONSHIP DCR ) -- to keep same cardinality

A faster response would be:

SELECT FROM SOMETHING S WHERE EXISTS ( SELECT 1 FROM DIFF_CARDINALITY_RELATIONSHIP DCR WHERE DCR.SOMETHING_ID = S.ID )

This isn't always possible but when available you will see a faster response.

stri_sub("abcde",-3,-1)
[1] "cde"

to install this package.

There are two main ways that you can do this. One of them is the standard CakePHP way, and the other is using a custom join.

It's worth pointing out that this advice is for CakePHP 2.x, not 3.x.

The CakePHP Way

You would create a relationship with your User model and Messages Model, and use the containable behavior:

class User extends AppModel {
    public $actsAs = array('Containable');
    public $hasMany = array('Message');
}

class Message extends AppModel {
    public $actsAs = array('Containable');
    public $belongsTo = array('User');
}

You need to change the messages.from column to be messages.user_id so that cake can automagically associate the records for you.

Then you can do this from the messages controller:

$this->Message->find('all', array(
    'contain' => array('User')
    'conditions' => array(
        'Message.to' => 4
    ),
    'order' => 'Message.datetime DESC'
));

The (other) CakePHP way

I recommend using the first method, because it will save you a lot of time and work. The first method also does the groundwork of setting up a relationship which can be used for any number of other find calls and conditions besides the one you need now. However, cakePHP does support a syntax for defining your own joins. It would be done like this, from the MessagesController:

$this->Message->find('all', array(
    'joins' => array(
        array(
            'table' => 'users',
            'alias' => 'UserJoin',
            'type' => 'INNER',
            'conditions' => array(
                'UserJoin.id = Message.from'
            )
        )
    ),
    'conditions' => array(
        'Message.to' => 4
    ),
    'fields' => array('UserJoin.*', 'Message.*'),
    'order' => 'Message.datetime DESC'
));

Note, I've left the field name messages.from the same as your current table in this example.

Using two relationships to the same model

Here is how you can do the first example using two relationships to the same model:

class User extends AppModel {
    public $actsAs = array('Containable');
    public $hasMany = array(
        'MessagesSent' => array(
            'className'  => 'Message',
            'foreignKey' => 'from'
         )
    );
    public $belongsTo = array(
        'MessagesReceived' => array(
            'className'  => 'Message',
            'foreignKey' => 'to'
         )
    );
}

class Message extends AppModel {
    public $actsAs = array('Containable');
    public $belongsTo = array(
        'UserFrom' => array(
            'className'  => 'User',
            'foreignKey' => 'from'
        )
    );
    public $hasMany = array(
        'UserTo' => array(
            'className'  => 'User',
            'foreignKey' => 'to'
        )
    );
}

Now you can do your find call like this:

$this->Message->find('all', array(
    'contain' => array('UserFrom')
    'conditions' => array(
        'Message.to' => 4
    ),
    'order' => 'Message.datetime DESC'
));

The only difference is that CHARACTER VARYING is more human friendly than VARCHAR

Delete the file(index.php) from your xampp folder, you will get the list of directories and files from htdocs folder.

There is no dict literal to create dict-inherited classes, custom dict classes with additional methods. In such case custom dict class constructor should be used, for example:

class NestedDict(dict):

    # ... skipped

state_type_map = NestedDict(**{
    'owns': 'Another',
    'uses': 'Another',
})

Use composition:

class ClassC
{
    public ClassA A { get; set; }
    public ClassB B { get; set; }   

    public C (ClassA  a, ClassB  b)
    {
        this.A = a;
        this.B = b;
    }
}

Then you can call C.A.DoA(). You also can change the properties to an interface or abstract class, like public InterfaceA A or public AbstractClassA A.

For space between the check mark and the text use:

android:paddingLeft="10dp"

But it becomes more than 10dp, because the check mark contains padding (about 5dp) around. If you want to remove padding, see How to remove padding around Android CheckBox:

android:paddingLeft="-5dp"
android:layout_marginStart="-5dp"
android:layout_marginLeft="-5dp"
// or android:translationX="-5dp" instead of layout_marginLeft

Spring has some standard events which you can handle.

To do that, you must create and register a bean that implements the ApplicationListener interface, something like this:

package test.pack.age;

import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationEvent;
import org.springframework.context.ApplicationListener;
import org.springframework.context.event.ContextRefreshedEvent;

public class ApplicationListenerBean implements ApplicationListener {

    @Override
    public void onApplicationEvent(ApplicationEvent event) {
        if (event instanceof ContextRefreshedEvent) {
            ApplicationContext applicationContext = ((ContextRefreshedEvent) event).getApplicationContext();
            // now you can do applicationContext.getBean(...)
            // ...
        }
    }
}

You then register this bean within your servlet.xml or applicationContext.xml file:

<bean id="eventListenerBean" class="test.pack.age.ApplicationListenerBean" />

and Spring will notify it when the application context is initialized.

In Spring 3 (if you are using this version), the ApplicationListener class is generic and you can declare the event type that you are interested in, and the event will be filtered accordingly. You can simplify a bit your bean code like this:

public class ApplicationListenerBean implements ApplicationListener<ContextRefreshedEvent> {

    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {
        ApplicationContext applicationContext = event.getApplicationContext();
        // now you can do applicationContext.getBean(...)
        // ...
    }
}

Vanilla Javascript:

this.querySelector(':checked').getAttribute('data-id')

@BrainSlugs83

You shouldn't blindly trust everything posted on stackoverflow. The comment in Jens code is incorrect, the parameter doesn't control whether exceptions are thrown or not.

MSDN is very clear what that parameter controls, have you read it? http://msdn.microsoft.com/en-us/library/dd321703(v=vs.110).aspx

If throwOnFirstException is true, an exception will immediately propagate out of the call to Cancel, preventing the remaining callbacks and cancelable operations from being processed. If throwOnFirstException is false, this overload will aggregate any exceptions thrown into an AggregateException, such that one callback throwing an exception will not prevent other registered callbacks from being executed.

The variable name is also wrong because Cancel is called on CancellationTokenSource not the token itself and the source changes state of each token it manages.

Omit row if either of two specific columns contain <NA>.

A little late but I wanted to add the solution I used to solve this problem. I found the solution here.

Anyway, the question seems to be asking 'how to start a new project from a branch of another repo?'

To this, the solution I used would be to first create a new repo in github or where ever. This will serve as the repo to your new project.

On your local machine, navigate to the project that has the branch you want to use as the template for your new project.

Run the command:

git push https://github.com/accountname/new-repo.git +old_branch:master

What this will do is push the old_branch to new-repo and make it the master branch of the new repo.

You then just have to clone the new repo down to your new project's local directory and you have a new project started at the old branch.

Try to avoid complete path references in the #include directive, whether they are absolute or relative. Instead, add the location of the other project's include folder in your project settings. Use only subfolders in path references when necessary. That way, it is easier to move things around without having to update your code.

A one liner but without String.format for all RGB colors:

Color your_color = new Color(128,128,128);

String hex = "#"+Integer.toHexString(your_color.getRGB()).substring(2);

You can add a .toUpperCase()if you want to switch to capital letters. Note, that this is valid (as asked in the question) for all RGB colors.

When you have ARGB colors you can use:

Color your_color = new Color(128,128,128,128);

String buf = Integer.toHexString(your_color.getRGB());
String hex = "#"+buf.substring(buf.length()-6);

A one liner is theoretically also possible but would require to call toHexString twice. I benchmarked the ARGB solution and compared it with String.format():

A vector is a container class while an array is an allocated memory.

In many cases,

display:inline;

is enough.

But in some cases, you have to add following:

clear:none;

According to this, you will need .NET 4.5 installed. For more details, visit the webpage. The gist of it is that after you have .NET 4.5 installed, your 4.0 apps will use the 4.5 System.dll. You can enable TLS 1.2 in two ways:

• At the beginning of the application, add this code: ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;
• Set the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319: SchUseStrongCrypto to DWORD 1

kennytm's links are dead and he doesn't provide an example so here's how you do substrings:

=MID(text, start_num, char_num)

Let's say cell A1 is Hello.

=MID(A1, 2, 3) 

Would return

ell

Because it says to start at character 2, e, and to return 3 characters.

I was going out of my mind when a rule was being ignored while others weren't. Run your CSS through a validator and look for parsing errors.

Whatever GET parameters you had will still be there and if like was a parameter before it will be overwritten, otherwise it will be included at the end.

Post data to backend using retrofit

}

The solution depends on the answer to the question - are all the parameters going to be the same type and if so will each be treated the same?

If the parameters are not the same type or more importantly are not going to be treated the same then you should use method overloading:

public class MyClass
{
  public void doSomething(int i) 
  {
    ...
  }

  public void doSomething(int i, String s) 
  {
    ...
  }

  public void doSomething(int i, String s, boolean b) 
  {
    ...
  }
}

If however each parameter is the same type and will be treated in the same way then you can use the variable args feature in Java:

public MyClass 
{
  public void doSomething(int... integers)
  {
    for (int i : integers) 
    {
      ...
    }
  }
}

Obviously when using variable args you can access each arg by its index but I would advise against this as in most cases it hints at a problem in your design. Likewise, if you find yourself doing type checks as you iterate over the arguments then your design needs a review.

Use this to get the page scroll position.

var screenTop = $(document).scrollTop();

$('#content').css('top', screenTop);

There is a really nice trick. My problem was that some really old C++ jni library leaked resources. At some point, it stopped functioning. The user tried to exit the app and launch it again -- with no result, because finishing an activity is not the same as finishing (or killing) the process. (By the way, the user could go to the list of the running applications and stop it from there -- this would work, but the users just do not know how to terminate applications.)

If you want to observe the effect of this feature, add a static variable to your activity and increment it each, say, button press. If you exit the application activity and then invoke the application again, this static variable will keep its value. (If the application really was exited, the variable would be assigned the initial value.)

(And I have to comment on why I did not want to fix the bug instead. The library was written decades ago and leaked resources ever since. The management believes it always worked. The cost of providing a fix instead of a workaround... I think, you get the idea.)

Now, how could I reset a jni shared (a.k.a. dynamic, .so) library to the initial state? I chose to restart application as a new process.

The trick is that System.exit() closes the current activity and Android recreates the application with one activity less.

So the code is:

/** This activity shows nothing; instead, it restarts the android process */
public class MagicAppRestart extends Activity {
    // Do not forget to add it to AndroidManifest.xml
    // <activity android:name="your.package.name.MagicAppRestart"/>
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        System.exit(0);
    }
    public static void doRestart(Activity anyActivity) {
        anyActivity.startActivity(new Intent(anyActivity.getApplicationContext(), MagicAppRestart.class));
    }
}

The calling activity just executes the code MagicAppRestart.doRestart(this);, the calling activity's onPause() is executed, and then the process is re-created. And do not forget to mention this activity in AndroidManifest.xml

The advantage of this method is that there is no delays.

UPD: it worked in Android 2.x, but in Android 4 something has changed.

Your error is in UpdaterServiceManager in onCreate and showNotification method.

You are trying to show notification from Service using Activity Context. Whereas Every Service has its own Context, just use the that. You don't need to pass a Service an Activity's Context.I don't see why you need a specific Activity's Context to show Notification.

Put your createNotification method in UpdateServiceManager.class. And remove CreateNotificationActivity not from Service.

You cannot display an application window/dialog through a Context that is not an Activity. Try passing a valid activity reference

You should just grab the window by the title bar and snap it to the left side of your screen (close browser) then reopen the browser ans snap it to the top... problem is over.

Once you're in the directory, just run it as ./myScript.sh

It is possible to make noncase sensitive URLs

Making Google.com..GOOGLE.com etc direct to google.com

You need to use the __getitem__ method.

class MyClass:
    def __getitem__(self, key):
        return key * 2

myobj = MyClass()
myobj[3] #Output: 6

And if you're going to be setting values you'll need to implement the __setitem__ method too, otherwise this will happen:

>>> myobj[5] = 1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: MyClass instance has no attribute '__setitem__'

The way to do this without use of plugins is to make a subclass of google's OverlayView() method.

https://developers.google.com/maps/documentation/javascript/reference?hl=en#OverlayView

You make a custom function and apply it to the map.

function Label() { 
    this.setMap(g.map);
};

Now you prototype your subclass and add HTML nodes:

Label.prototype = new google.maps.OverlayView; //subclassing google's overlayView
Label.prototype.onAdd = function() {
        this.MySpecialDiv               = document.createElement('div');
        this.MySpecialDiv.className     = 'MyLabel';
        this.getPanes().overlayImage.appendChild(this.MySpecialDiv); //attach it to overlay panes so it behaves like markers

}

you also have to implement remove and draw functions as stated in the API docs, or this won't work.

Label.prototype.onRemove = function() {
... // remove your stuff and its events if any
}
Label.prototype.draw = function() {
      var position = this.getProjection().fromLatLngToDivPixel(this.get('position')); // translate map latLng coords into DOM px coords for css positioning
var pos = this.get('position');
            $('.myLabel')
            .css({
                'top'   : position.y + 'px',
                'left'  : position.x + 'px'
            })
        ;
}

That's the gist of it, you'll have to do some more work in your specific implementation.

You can override UIButton's setHighlighted method.

Objective-C

- (void)setHighlighted:(BOOL)highlighted {
    [super setHighlighted:highlighted];

    if (highlighted) {
        self.backgroundColor = UIColorFromRGB(0x387038);
    } else {
        self.backgroundColor = UIColorFromRGB(0x5bb75b);
    }
}

Swift 3.0 and Swift 4.1

override open var isHighlighted: Bool {
    didSet {
        backgroundColor = isHighlighted ? UIColor.black : UIColor.white
    }
}

before you do other way, please do open php.exe on your PHP folder. run it and if you faced any error statement on it, you can fix it manually. else, do most-usefull post in this thread.

As you said, Safari sends Cache-Control: max-age=0 on reload. Express (or more specifically, Express's dependency, node-fresh) considers the cache stale when Cache-Control: no-cache headers are received, but it doesn't do the same for Cache-Control: max-age=0. From what I can tell, it probably should. But I'm not an expert on caching.

The fix is to change (what is currently) line 37 of node-fresh/index.js from

if (cc && cc.indexOf('no-cache') !== -1) return false;  

to

if (cc && (cc.indexOf('no-cache') !== -1 ||
  cc.indexOf('max-age=0') !== -1)) return false;

I forked node-fresh and express to include this fix in my project's package.json via npm, you could do the same. Here are my forks, for example:

https://github.com/stratusdata/node-fresh https://github.com/stratusdata/express#safari-reload-fix

The safari-reload-fix branch is based on the 3.4.7 tag.

The more general answer to this question involves shadowed variables and how they are accessed.

In the following example (from Oracle), the variable x in main() is shadowing Test.x:

class Test {
    static int x = 1;
    public static void main(String[] args) {
        InnerClass innerClassInstance = new InnerClass()
        {
            public void printX()
            {
                System.out.print("x=" + x);
                System.out.println(", Test.this.x=" + Test.this.x);
            }
        }
        innerClassInstance.printX();
    }

    public abstract static class InnerClass
    {
        int x = 0;

        public InnerClass() { }

        public abstract void printX();
    }
}

Running this program will print:

x=0, Test.this.x=1

Ionic Version: 1.0.1
Ionic CLI Version: 1.6.1
Ionic App Lib Version: 0.3.3
OS: Windows 7 SP1

Maybe a better solution would be to add an extra column that is automatically set to 1 on each row. As soon as there is an element that is not null change it to a 0.

then

If(drEntitity.rows[i].coulmn[8] = 1)
{
   dtEntity.Rows.Add(drEntity);
}
 else
 {
   //don't add, will create a new one (drEntity = dtEntity.NewRow();)
 }

It "maps" a function to each item in an Enumerable - in this case, a range. So it would call the block passed once for every integer from 0 to param_count (exclusive - you're right about the dots) and return an array containing each return value.

Here's the documentation for Enumerable#map. It also has an alias, collect.

I forgot to annotate my component with "@Input" (Doh!)

book-list.component.html (Offending code):

<app-book-item
  *ngFor="let book of book$ | async"
  [book]="book">  <-- Can't bind to 'book' since it isn't a known property of 'app-book-item'
</app-book-item>

Corrected version of book-item.component.ts:

import { Component, OnInit, Input } from '@angular/core';

import { Book } from '../model/book';
import { BookService } from '../services/book.service';

@Component({
  selector: 'app-book-item',
  templateUrl: './book-item.component.html',
  styleUrls: ['./book-item.component.css']
})
export class BookItemComponent implements OnInit {

  @Input()
  public book: Book;

  constructor(private bookService: BookService)  { }

  ngOnInit() {}

}

The fastest way i could find out is this :

var myArray = (byte[]) new ImageConverter().ConvertTo(InputImg, typeof(byte[]));

Hope to be useful

Simply use text-center class

 <div class="row">
     <div class="col-md-12">
          <h3 class="text-center">Here Comes your Text</h3>
     </div>
 </div>

It is common to have components that are only rendering from props. Like this:

class Template extends React.Component{
  render (){
    return <div>this.props.something</div>
  }
}

Then in your upper level component where you have the logic you just import the Template component and pass the needed props. All your logic stays in the higher level component, and the Template only renders. This is a possible way to achieve 'templates' like in Angular.

There is no way to have .jsx file with jsx only and use it in React because jsx is not really html but markup for a virtual DOM, which React manages.

Go and multiline strings

Using back ticks you can have multiline strings:

package main

import "fmt"

func main() {

    message := `This is a 
Multi-line Text String
Because it uses the raw-string back ticks 
instead of quotes.
`

    fmt.Printf("%s", message)
}

Instead of using either the double quote (“) or single quote symbols (‘), instead use back-ticks to define the start and end of the string. You can then wrap it across lines.

If you indent the string though, remember that the white space will count.

Please check the playground and do experiments with it.

You can better achieve it by using the DrawableCompat like this:

Drawable backgroundDrawable = view.getBackground();             
DrawableCompat.setTint(backgroundDrawable, newColor);

Write your permission before the application tag as given below.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.someapp.sample">

    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme">

You say "this is a piece of java code being written", from which I infer that there is still a chance that you could design it a different way.

Having an ArrayList is like having a collection of stuff. Rather than force the instanceof or getClass every time you take an object from the list, why not design the system so that you get the type of the object when you retrieve it from the DB, and store it into a collection of the appropriate type of object?

Or, you could use one of the many data access libraries that exist to do this for you.

If you already using jQuery simple:

<input type="file" onChange="$(this).closest('form').submit()"/>

You can use a .Net environment Visual studio, Take a look at the differences with the PC version.

A lighter editor would be Visual Code

Alternatives :

1. Installing the Mono Project runtime . It allows you to re-compile the code and run it on a Mac, but this requires various alterations to the codebase, as the fuller .Net Framework is not available. (Also, WPF applications aren't supported here either.)

2. Virtual machine (VMWare Fusion perhaps)

3. Update your codebase to .Net Core, (before choosing this option take a look at this migration process)

   • .Net Core 3.1 is an open-source, free and available on Window, MacOs and Linux

   • As of September 14, a release candidate ¹ of .Net Core 5.0 has been deployed on Window, MacOs and Linux.

That SSL error is misleading. I am using Anaconda 3, conda version 4.6.11, have the most current version of openssl on a Windows 10 instance. I got the issue resolved by changing the security settings on the Anaconda3 folder to Full Control. Don't think this helped, but I also have modified the ..\Anaconda3\Lib\site-packages\certifi\cacert.pem file to include the company's SSL cert.

Hope this info helps you.

Here is the another solution. Please check this.

$first = '10/30/2017'; //starting date
$last= '10/11/2017';   //ending date
$first_time_arr=explode('/',$first); 
$last_time_arr=explode('/',$last);
//create timestamp of starting date
$start_timestamp=mktime(0,0,0, $first_time_arr[0], $first_time_arr[1],$first_time_arr[2]);
//create timestamp of ending date
$end_timestamp=mktime(0,0,0, $last_time_arr[0], $last_time_arr[1],$last_time_arr[2]);
$date_arr=array();
for($i=$start_timestamp;$i<=$end_timestamp;$i=$i+86400){
    $date_arr[]=date("Y-m-d",$i); //this will save all dates in array
}

db.users.count()
db.users.remove({})
db.users.count()

In Java 8, it can be done using

String[] arrayFromList = fromlist.stream().toArray(String[]::new);

a simple way would be to cast the dates into timestamps and take their difference and then extract the DAY part.

if you want real difference

select extract(day from 'DATE_A'::timestamp - 'DATE_B':timestamp);

if you want absolute difference

select abs(extract(day from 'DATE_A'::timestamp - 'DATE_B':timestamp));

Had a similar issue. Here are the steps used to setup SSH keys and forwarding on the Mac. Made these notes for myself - may help someone... check against your config.

The assumption here is there are no keys setup. If you already have the keys setup skip this section.

$ ssh-keygen -t rsa -b 4096

Generating public/private rsa key pair.

Enter a file in which to save the key (/Users/you/.ssh/id_rsa): [Press enter] Enter passphrase (empty for no passphrase): [Type a passphrase] Enter same passphrase again: [Type passphrase again]

Modify ~/.ssh/config adding the entry for the key file:

~/.ssh/config should look similar to:

Host *

AddKeysToAgent yes

UseKeychain yes

IdentityFile ~/.ssh/id_rsa

Store the private key in the keychain:

$ ssh-add -K ~/.ssh/id_rsa

Go test it now with: ssh -A username@yourhostname

Should forward your key to yourhostname. Assuming your keys are added on you should connect without issue.

Do pip3 install PyMySQL and then pip3 install mysqlclient. Worked for me

text/javascript is obsolete, and application/x-javascript was experimental (hence the x- prefix) for a transitional period until application/javascript could be standardised.

You should use application/javascript. This is documented in the RFC.

As far a browsers are concerned, there is no difference (at least in HTTP headers). This was just a change so that the text/* and application/* MIME type groups had a consistent meaning where possible. (text/* MIME types are intended for human readable content, JavaScript is not designed to directly convey meaning to humans).

Note that using application/javascript in the type attribute of a script element will cause the script to be ignored (as being in an unknown language) in some older browsers. Either continue to use text/javascript there or omit the attribute entirely (which is permitted in HTML 5).

This isn't a problem in HTTP headers as browsers universally (as far as I'm aware) either ignore the HTTP content-type of scripts entirely, or are modern enough to recognise application/javascript.

Kotlin Answer

for ((key, value) in map.entries) {
    // do something with `key`
    // so something with `value`
}

You may find other solutions that include filterValues. Just keep in mind that retrieving a Key value using filterValues will include braces [].

val key = map.filterValues {it = position}.keys

Very old question, but since google led me here I'll add a solution that I found useful:

Step 1. Create a user for each schema you need to be able to use. E.g. "user_myschema"

Step 2. Use EXECUTE AS to execute the SQL statements as the required schema user.

Step 3. Use REVERT to switch back to the original user.

Example: Let's say you have a table "mytable" present in schema "otherschema", which is not your default schema. Running "SELECT * FROM mytable" won't work.

Create a user named "user_otherschema" and set that user's default schema to be "otherschema".

Now you can run this script to interact with the table:

EXECUTE AS USER = 'user_otherschema';
SELECT * FROM mytable
REVERT

The revert statements resets current user, so you are yourself again.

Link to EXECUTE AS documentation: https://docs.microsoft.com/en-us/sql/t-sql/statements/execute-as-transact-sql?view=sql-server-2017

Bit more detail:

    private void Form1_Load(object sender, EventArgs e)
    {
        Timer MyTimer = new Timer();
        MyTimer.Interval = (45 * 60 * 1000); // 45 mins
        MyTimer.Tick += new EventHandler(MyTimer_Tick);
        MyTimer.Start();
    }

    private void MyTimer_Tick(object sender, EventArgs e)
    {
        MessageBox.Show("The form will now be closed.", "Time Elapsed");
        this.Close();
    }

How to create symlink in vagrant. Steps:

1. In vagrant file create a synced folder. e.g config.vm.synced_folder "F:/Sunburst/source/sunburst/lms", "/source" F:/Sunburst/source/sunburst/lms :- where the source code, /source :- directory path inside the vagrant
2. Vagrant up and type vagrant ssh and go to source directory e.g cd source
3. Verify your source code folder structure is available in the source directory. e.g /source/local
4. Then go to the guest machine directory where the files which are associate with the browser. After get backup of the file. e.g sudo mv local local_bk
5. Then create symlink e.g sudo ln -s /source/local local. local mean link-name (folder name in guest machine which you are going to link) if you need to remove the symlink :- Type sudo rm local

As I have not found any simple script so far, here's my two cents:

set ELEVATE_APP=Full command line without parameters for the app to run
set ELEVATE_PARMS=The actual parameters for the app
echo Set objShell = CreateObject("Shell.Application") >elevatedapp.vbs
echo Set objWshShell = WScript.CreateObject("WScript.Shell") >>elevatedapp.vbs
echo Set objWshProcessEnv = objWshShell.Environment("PROCESS") >>elevatedapp.vbs
echo objShell.ShellExecute "%ELEVATE_APP%", "%ELEVATE_PARMS%", "", "runas" >>elevatedapp.vbs
DEL elevatedapp.vbs

Try this:

if [ ${STATUS} -ne 100 -a "${STRING}" = "${VALUE}" ]

or

if [ ${STATUS} -ne 100 ] && [ "${STRING}" = "${VALUE}" ]

Set the value it will set it as selected option for dropdown:

$("#salesrep").val("Bruce Jones");

Here is working Demo

If it still not working:

1. Please check JavaScript errors on console.
2. Make sure you included jquery files
3. your network is not blocking jquery file if using externally.
4. Check your view source some time exact copy of element stop jquery to work correctly

The solution for me on a CentOS 8 system was checking the System Cryptography Policy by verifying the /etc/crypto-policies/config reads the default value of DEFAULT rather than any other value.

Once changing this value to DEFAULT, run the following command:

/usr/bin/update-crypto-policies --set DEFAULT

Rerun the curl command and it should work.

Highcharts will automatically try to find the best format for the current zoom-range. This is done if the xAxis has the type 'datetime'. Next the unit of the current zoom is calculated, it could be one of:

• second
• minute
• hour
• day
• week
• month
• year

This unit is then used find a format for the axis labels. The default patterns are:

second: '%H:%M:%S',
minute: '%H:%M',
hour: '%H:%M',
day: '%e. %b',
week: '%e. %b',
month: '%b \'%y',
year: '%Y'

If you want the day to be part of the "hour"-level labels you should change the dateTimeLabelFormats option for that level include %d or %e. These are the available patters:

• %a: Short weekday, like 'Mon'.
• %A: Long weekday, like 'Monday'.
• %d: Two digit day of the month, 01 to 31.
• %e: Day of the month, 1 through 31.
• %b: Short month, like 'Jan'.
• %B: Long month, like 'January'.
• %m: Two digit month number, 01 through 12.
• %y: Two digits year, like 09 for 2009.
• %Y: Four digits year, like 2009.
• %H: Two digits hours in 24h format, 00 through 23.
• %I: Two digits hours in 12h format, 00 through 11.
• %l (Lower case L): Hours in 12h format, 1 through 11.
• %M: Two digits minutes, 00 through 59.
• %p: Upper case AM or PM.
• %P: Lower case AM or PM.
• %S: Two digits seconds, 00 through 59

You can use netstat command

netstat --listen

To display open ports and established TCP connections,

netstat -vatn

To display only open UDP ports try the following command:

netstat -vaun

decimal d = 3.00 is still 3. I guess you want to show it some where on screen or print it on log file as 3.00. You can do following

string str = d.ToString("F2");

or if you are using database to store the decimal then you can set pricision value in database.

Here is one possiblity for you if you are using Bootstrap 3

I'm using the resposive table code from http://getbootstrap.com/css/#tables-responsive

ie:

<div class="table-responsive">
<table class="table">
...
</table>
</div>

http://msdn.microsoft.com/en-us/library/k6h9cz8h.aspx - See this on registering IIS for ASP.NET 4.0

Instead of using config files you can use a configuration database with a scoped systemConfig table and add all your settings there.

CREATE TABLE [dbo].[SystemConfig]  
    (  
      [Id] [int] IDENTITY(1, 1)  
                 NOT NULL ,  
      [AppName] [varchar](128) NULL ,  
      [ScopeName] [varchar](128) NOT NULL ,  
      [Key] [varchar](256) NOT NULL ,  
      [Value] [varchar](MAX) NOT NULL ,  
      CONSTRAINT [PK_SystemConfig_ID] PRIMARY KEY NONCLUSTERED ( [Id] ASC )  
        WITH ( PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF,  
               IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON,  
               ALLOW_PAGE_LOCKS = ON ) ON [PRIMARY]  
    )  
ON  [PRIMARY]  

GO  

SET ANSI_PADDING OFF  
GO  

ALTER TABLE [dbo].[SystemConfig] ADD  CONSTRAINT [DF_SystemConfig_ScopeName]  DEFAULT ('SystemConfig') FOR [ScopeName]  
GO 

With such configuration table you can create rows like such:

Then from your your application dal(s) wrapping EF you can easily retrieve the scoped configuration.
If you are not using dal(s) and working in the wire directly with EF, you can make an Entity from the SystemConfig table and use the value depending on the application you are on.

You need to create a new Row with the values from dr first. A DataRow can only belong to a single DataTable.

You can also use Add which takes an array of values:

myTable.Rows.Add(dr.ItemArray)

Or probably even better:

// This works because the row was added to the original table.
myTable.ImportRow(dr);

// The following won't work. No data will be added or exception thrown.
var drFail = dt.NewRow()
drFail["CustomerID"] = "[Your data here]";
// dt.Rows.Add(row); // Uncomment for import to succeed.
myTable.ImportRow(drFail);

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "scr", "javascript:test();", true);

It's not clear what you want, or whether you want this trick to work with different targets, or whether you've defined these targets elsewhere, or what version of Make you're using, but what the heck, I'll go out on a limb:

ifeq (yes, ${TEST})
CXXFLAGS := ${CXXFLAGS} -DDESKTOP_TEST
test:
$(info ************  TEST VERSION ************)
else
release:
$(info ************ RELEASE VERSIOIN **********)
endif

cant say why, but the es5/6 syntax doesnt work

This is how I finally did it! You can put a layer (full sized) over your body with high z-index and, of course hidden. You will make it visible when the window is open, make it focused on click over parent window (the layer), and finally will disappear it when the opened window is closed or submitted or whatever.

      .layer
  {
        position: fixed;
        opacity: 0.7;
        left: 0px;
        top: 0px;
        width: 100%;
        height: 100%;
        z-index: 999999;
        background-color: #BEBEBE;
        display: none;
        cursor: not-allowed;
  }

and layer in the body:

                <div class="layout" id="layout"></div>

function that opens the popup window:

    var new_window;
    function winOpen(){
        $(".layer").show();
        new_window=window.open(srcurl,'','height=750,width=700,left=300,top=200');
    }

keeping new window focused:

         $(document).ready(function(){
             $(".layout").click(function(e) {
                new_window.focus();
            }
        });

and in the opened window:

    function submit(){
        var doc = window.opener.document,
        doc.getElementById("layer").style.display="none";
         window.close();
    }   

   window.onbeforeunload = function(){
        var doc = window.opener.document;
        doc.getElementById("layout").style.display="none";
   }

I hope it would help :-)

Please put this code in head section

<link href='http://fonts.googleapis.com/css?family=Lato:400,700' rel='stylesheet' type='text/css'>

and use font-family: 'Lato', sans-serif; in your css. For example:

h1 {
    font-family: 'Lato', sans-serif;
    font-weight: 400;
}

Or you can use manually also

Generate .ttf font from fontSquiral

and can try this option

    @font-face {
        font-family: "Lato";
        src: url('698242188-Lato-Bla.eot');
        src: url('698242188-Lato-Bla.eot?#iefix') format('embedded-opentype'),
        url('698242188-Lato-Bla.svg#Lato Black') format('svg'),
        url('698242188-Lato-Bla.woff') format('woff'),
        url('698242188-Lato-Bla.ttf') format('truetype');
        font-weight: normal;
        font-style: normal;
}

Called like this

body {
  font-family: 'Lato', sans-serif;
}

It didn't. Your compiler did, but there's still a debug symbol for the original variable name.

If you want to use SQL Server Management Studio, you want to install the full Oracle client, not the Instant Client. The full Oracle client is on the same download page as the Oracle database. Assuming that you are installing on a 64-bit version of Windows, I expect you want the "Oracle Database 11g Release 2 Client (11.2.0.1.0) for Microsoft Windows (x64)" download. This is several hundred MB rather than a couple of MB for the Instant Client.

Hello I am trying to add new session values in node js like

req.session.portal = false
Passport.authenticate('facebook', (req, res, next) => {
    next()
})(req, res, next)

On passport strategies I am not getting portal value in mozilla request but working fine with chrome and opera

FacebookStrategy: new PassportFacebook.Strategy({
    clientID: Configuration.SocialChannel.Facebook.AppId,
    clientSecret: Configuration.SocialChannel.Facebook.AppSecret,
    callbackURL: Configuration.SocialChannel.Facebook.CallbackURL,
    profileFields: Configuration.SocialChannel.Facebook.Fields,
    scope: Configuration.SocialChannel.Facebook.Scope,
    passReqToCallback: true
}, (req, accessToken, refreshToken, profile, done) => {
    console.log(JSON.stringify(req.session));

You should create an installer, as mentioned before. Even though it is also possible to let py2exe bundle everything into a single executable, by setting bundle_files option to 1 and the zipfile keyword argument to None, I don't recommend this for PyGTK applications.

That's because of GTK+ tries to load its data files (locals, themes, etc.) from the directory it was loaded from. So you have to make sure that the directory of your executable contains also the libraries used by GTK+ and the directories lib, share and etc from your installation of GTK+. Otherwise you will get problems running your application on a machine where GTK+ is not installed system-wide.

For more details read my guide to py2exe for PyGTK applications. It also explains how to bundle everything, but GTK+.

Other way to get the minor version is:

SELECT extversion
FROM pg_catalog.pg_extension
WHERE extname='postgis'

You could use sp_executesql instead of exec. That allows you to specify an output parameter.

declare @out_var varchar(max);
execute sp_executesql 
    N'select @out_var = ''hello world''', 
    N'@out_var varchar(max) OUTPUT', 
    @out_var = @out_var output;
select @out_var;

This prints "hello world".

To retain order of the rows:

UPDATE thetable SET rowid=col_serial FROM 
(SELECT rowid, row_number() OVER ( ORDER BY lngid) AS col_serial FROM thetable ORDER BY lngid) AS t1 
WHERE thetable.rowid=t1.rowid;

Step-1: Your Model class

public class RechargeMobileViewModel
    {
        public string CustomerFullName { get; set; }
        public string TelecomSubscriber { get; set; }
        public int TotalAmount { get; set; }
        public string MobileNumber { get; set; }
        public int Month { get; set; }
        public List<SelectListItem> getAllDaysList { get; set; }

        // Define the list which you have to show in Drop down List
        public List<SelectListItem> getAllWeekDaysList()
        {
            List<SelectListItem> myList = new List<SelectListItem>();
            var data = new[]{
                 new SelectListItem{ Value="1",Text="Monday"},
                 new SelectListItem{ Value="2",Text="Tuesday"},
                 new SelectListItem{ Value="3",Text="Wednesday"},
                 new SelectListItem{ Value="4",Text="Thrusday"},
                 new SelectListItem{ Value="5",Text="Friday"},
                 new SelectListItem{ Value="6",Text="Saturday"},
                 new SelectListItem{ Value="7",Text="Sunday"},
             };
            myList = data.ToList();
            return myList;
        }
}

Step-2: Call this method to fill Drop down in your controller Action

namespace MvcVariousApplication.Controllers
    {
        public class HomeController : Controller
        {
            public ActionResult Index()
            {
              RechargeMobileViewModel objModel = new RechargeMobileViewModel();
                objModel.getAllDaysList = objModel.getAllWeekDaysList();  
                return View(objModel);
            }
    }
    }

Step-3: Fill your Drop-Down List of View as follows

 @model MvcVariousApplication.Models.RechargeMobileViewModel
    @{
        ViewBag.Title = "Contact";
    }
    @Html.LabelFor(model=> model.CustomerFullName)
    @Html.TextBoxFor(model => model.CustomerFullName)

    @Html.LabelFor(model => model.MobileNumber)
    @Html.TextBoxFor(model => model.MobileNumber)

    @Html.LabelFor(model => model.TelecomSubscriber)
    @Html.TextBoxFor(model => model.TelecomSubscriber)

    @Html.LabelFor(model => model.TotalAmount)
    @Html.TextBoxFor(model => model.TotalAmount)

    @Html.LabelFor(model => model.Month)
    @Html.DropDownListFor(model => model.Month, new SelectList(Model.getAllDaysList, "Value", "Text"), "-Select Day-")

In the course of learning regular expression, I was really stuck in the metacharacter which is \b. I indeed didn't comprehend its meaning while I was asking myself "what it is, what it is" repetitively. After some attempts by using the website, I watch out the pink vertical dashes at the every beginning of words and at the end of words. I got it its meaning well at that time. It's now exactly word(\w)-boundary.

My view is merely to immensely understanding-oriented. Logic behind of it should be examined from another answers.

The general approach is to convert the data to long format (using melt() from package reshape or reshape2) or gather()/pivot_longer() from the tidyr package:

library("reshape2")
library("ggplot2")

test_data_long <- melt(test_data, id="date")  # convert to long format

ggplot(data=test_data_long,
       aes(x=date, y=value, colour=variable)) +
       geom_line()

Also see this question on reshaping data from wide to long.

Use:

Dim n As String = MsgBox("Do you really want to exit?", MsgBoxStyle.YesNo, "Confirmation Dialog Box")
If n = vbYes Then
    MsgBox("Current Form is closed....")
    Me.Close() 'Current Form Closed
    Yogi_Cottex.Show() 'Form Name.show()
End If

If I understand your question right you are asking what is difference if you register listener callback with $watch or if you do it with $observe.

Callback registerd with $watch is fired when $digest is executed.

Callback registered with $observe are called when value changes of attributes that contain interpolation (e.g. attr="{{notJetInterpolated}}").

Inside directive you can use both of them on very similar way:

    attrs.$observe('attrYouWatch', function() {
         // body
    });

or

    scope.$watch(attrs['attrYouWatch'], function() {
         // body
    });

<input id="name" type="text" #myInput />
{{ myInput.focus() }}

this is the best and simplest way, because code "myInput.focus()" runs after input created

WARNING: this solution is acceptable only if you have single element in the form (user will be not able to select other elements)

If you need to pass a variable along with the 'this' keyword, the below code works:

var status = 'Active';
var anchorHTML = '<a href ="#" onClick = "DisplayActiveStatus(this,\'' + status + '\')">' + data+ '</a>';

Download the bootbox typings

Then add a reference to it inside your .ts file.

First of all, you need to login as root and than go to /etc directory and execute some commands which are given below.

[root@localhost~]# cd /etc
[root@localhost /etc]# vi sudoers

and enter this line at the end

kundan ALL=NOPASSWD: ALL

where kundan is the username and than save it. and then try to transfer the file and add sudo as a prefix to the command you want to execute:

sudo cp hello.txt /home/rahul/program/

where rahul is the second user in the same server.

//To open the form

Form2 form2 = new Form2();

form2.Show();
// And to close
form2.Close();

Hope this helps

I also used the base_path() function and it worked for me.

You'll want a Map<String, String>. Classes that implement the Map interface include (but are not limited to):

• HashMap
• LinkedHashMap
• Hashtable

Each is designed/optimized for certain situations (go to their respective docs for more info). HashMap is probably the most common; the go-to default.

For example (using a HashMap):

Map<String, String> map = new HashMap<String, String>();
map.put("dog", "type of animal");
System.out.println(map.get("dog"));

type of animal

So you're trying to grab numeric values that are preceded by the token "%download%#"?

Try this pattern:

(?<=%download%#)\d+

That should work. I don't think # or % are special characters in .NET Regex, but you'll have to either escape the backslash like \\ or use a verbatim string for the whole pattern:

var regex = new Regex(@"(?<=%download%#)\d+");
return regex.Matches(strInput);

Tested here: http://rextester.com/BLYCC16700

NOTE: The lookbehind assertion (?<=...) is important because you don't want to include %download%# in your results, only the numbers after it. However, your example appears to require it before each string you want to capture. The lookbehind group will make sure it's there in the input string, but won't include it in the returned results. More on lookaround assertions here.

Instead of using the instance with the scope resolution operator :: because it wasn't defined like static function.

$r=Page::getInstanceByName($page);

change it to :

$r=Page->getInstanceByName($page);

And it will work like a charm.

With JavaScript

1. var a = document.createElement('a');
   a.setAttribute('href',desiredLink);
   a.innerHTML = desiredText;
   // apend the anchor to the body
   // of course you can append it almost to any other dom element
   document.getElementsByTagName('body')[0].appendChild(a);
   

2. document.getElementsByTagName('body')[0].innerHTML += '<a href="'+desiredLink+'">'+desiredText+'</a>';
   

   or, as suggested by @travis :

   document.getElementsByTagName('body')[0].innerHTML += desiredText.link(desiredLink);
   

3. <script type="text/javascript">
   //note that this case can be used only inside the "body" element
   document.write('<a href="'+desiredLink+'">'+desiredText+'</a>');
   </script>
   

With JQuery

1. $('<a href="'+desiredLink+'">'+desiredText+'</a>').appendTo($('body'));
   

2. $('body').append($('<a href="'+desiredLink+'">'+desiredText+'</a>'));
   

3. var a = $('<a />');
   a.attr('href',desiredLink);
   a.text(desiredText);
   $('body').append(a);
   

In all the above examples you can append the anchor to any element, not just to the 'body', and desiredLink is a variable that holds the address that your anchor element points to, and desiredText is a variable that holds the text that will be displayed in the anchor element.

To see non-staged (non-added) changes to existing files

git diff

Note that this does not track new files. To see staged, non-commited changes

git diff --cached

I think you cannot get it as String but you can get it as int by get resource id:

int resId = this.getResources().getIdentifier("imageNameHere", "drawable", this.getPackageName());

To center align text

input[type='text'] { text-align:center;}

To center align the textbox in the container that it sits in, apply text-align:center to the container.

As above(Kai) or do the following. Really enums are "Enumerations", what you want to do is have a set, therefore you should really use stl::set

enum AnimalFlags
{
    HasClaws = 1,
    CanFly =2,
    EatsFish = 4,
    Endangered = 8
};

int main(void)
{
    AnimalFlags seahawk;
    //seahawk= CanFly | EatsFish | Endangered;
    seahawk= static_cast<AnimalFlags>(CanFly | EatsFish | Endangered);
}

There you go :

The following should work, but you may need to change the format:

echo date('l F jS, Y (m-d-Y)', strtotime('+3 months', strtotime($DateToAdjust)));

Use $ before " " it will allow to write variables between these brackets

 Console.WriteLine($"{mon}.{da}.{yer}");

The pro way :

  Console.WriteLine($"{DateTime.Today.Month}.{DateTime.Today.Day}.{DateTime.Today.Year}");
  Console.WriteLine($"month{DateTime.Today.Month} day{DateTime.Today.Day} year{DateTime.Today.Year}");

5.24.2016

One of the way you can achieve this is:

1. Create an executable Jar file
2. Create a batch file to run the above jar and launch the desktop java application.
3. Use Batch2Exe converter and covert to batch file to Exe.
4. During above conversion, you can change the icon to that of your choice.(must of valid .ico file)
5. Place the short cut for the above exe on desktop.

Now your java program can be opened in a fancy way just like any other MSWindows apps.! :)

The problem is that '_' underscores are not valid in header attribute. If removing the underscore is not an option you can add to the server block:

underscores_in_headers on;

This is basically a copy and paste from @kishorer747 comment on @Fleshgrinder answer, and solution is from: https://serverfault.com/questions/586970/nginx-is-not-forwarding-a-header-value-when-using-proxy-pass/586997#586997

I added it here as in my case the application behind nginx was working perfectly fine, but as soon ngix was between my flask app and the client, my flask app would not see the headers any longer. It was kind of time consuming to debug.

The border css property will increase all elements "outer" size, excepts tds in tables. You can get a visual idea of how this works in Firebug (discontinued), under the html->layout tab.

Just as an example, a div with a width and height of 10px and a border of 1px, will have an outer width and height of 12px.

For your case, to make it appear like the border is on the "inside" of the div, in your selected CSS class, you can reduce the width and height of the element by double your border size, or you can do the same for the elements padding.

Eg:

div.navitem
{
    width: 15px;
    height: 15px;
    /* padding: 5px; */
}

div.navitem .selected
{
    border: 1px solid;
    width: 13px;
    height: 13px;
    /* padding: 4px */
}

You should set responseType: ResponseContentType.Blob in your GET-Request settings, because so you can get your image as blob and convert it later da base64-encoded source. You code above is not good. If you would like to do this correctly, then create separate service to get images from API. Beacuse it ism't good to call HTTP-Request in components.

Here is an working example:

Create image.service.ts and put following code:

Angular 4:

getImage(imageUrl: string): Observable<File> {
    return this.http
        .get(imageUrl, { responseType: ResponseContentType.Blob })
        .map((res: Response) => res.blob());
}

Angular 5+:

getImage(imageUrl: string): Observable<Blob> {
  return this.httpClient.get(imageUrl, { responseType: 'blob' });
}

Important: Since Angular 5+ you should use the new HttpClient.

The new HttpClient returns JSON by default. If you need other response type, so you can specify that by setting responseType: 'blob'. Read more about that here.

Now you need to create some function in your image.component.ts to get image and show it in html.

For creating an image from Blob you need to use JavaScript's FileReader. Here is function which creates new FileReader and listen to FileReader's load-Event. As result this function returns base64-encoded image, which you can use in img src-attribute:

imageToShow: any;

createImageFromBlob(image: Blob) {
   let reader = new FileReader();
   reader.addEventListener("load", () => {
      this.imageToShow = reader.result;
   }, false);

   if (image) {
      reader.readAsDataURL(image);
   }
}

Now you should use your created ImageService to get image from api. You should to subscribe to data and give this data to createImageFromBlob-function. Here is an example function:

getImageFromService() {
      this.isImageLoading = true;
      this.imageService.getImage(yourImageUrl).subscribe(data => {
        this.createImageFromBlob(data);
        this.isImageLoading = false;
      }, error => {
        this.isImageLoading = false;
        console.log(error);
      });
}

Now you can use your imageToShow-variable in HTML template like this:

<img [src]="imageToShow"
     alt="Place image title"
     *ngIf="!isImageLoading; else noImageFound">
<ng-template #noImageFound>
     <img src="fallbackImage.png" alt="Fallbackimage">
</ng-template>

I hope this description is clear to understand and you can use it in your project.

See the working example for Angular 5+ here.

Make a div 100% wide and 100% high. Then set a background image.

$ heroku config:set DISABLE_COLLECTSTATIC=1

after

$ git push heroku master

Remember before you merge you need to update the tag, it's quite different from branches (git pull origin tag_name won't update your local tags). Thus, you need the following command:

git fetch --tags origin

Then you can perform git merge tag_name to merge the tag onto a branch.

Javascript doesn't have access to the user's filesystem for security reasons. FileReader is only for files manually selected by the user.

It can be simplify to this:

<button onclick="return confirm('Are you sure you want to delete?');" />

The behaviour may be undefined, but that just means there isn't a "standard". All decent compilers offer #pragmas to control packing and alignment, but may have different defaults. The defaults will also change depending on the optimisation settings used.

Also, unions are not just for saving space. They can help modern compilers with type punning. If you reinterpret_cast<> everything the compiler can't make assumptions about what you are doing. It may have to throw away what it knows about your type and start again (forcing a write back to memory, which is very inefficient these days compared to CPU clock speed).

If you want to test explicitly for valid JSON (as opposed to the absence of the returned value false), then you can use a parsing approach as described here.

To make an Ajax request using jQuery you can do this by the following code.

HTML:

<form id="foo">
    <label for="bar">A bar</label>
    <input id="bar" name="bar" type="text" value="" />
    <input type="submit" value="Send" />
</form>

<!-- The result of the search will be rendered inside this div -->
<div id="result"></div>

JavaScript:

Method 1

 /* Get from elements values */
 var values = $(this).serialize();

 $.ajax({
        url: "test.php",
        type: "post",
        data: values ,
        success: function (response) {

           // You will get response from your PHP page (what you echo or print)
        },
        error: function(jqXHR, textStatus, errorThrown) {
           console.log(textStatus, errorThrown);
        }
    });

Method 2

/* Attach a submit handler to the form */
$("#foo").submit(function(event) {
    var ajaxRequest;

    /* Stop form from submitting normally */
    event.preventDefault();

    /* Clear result div*/
    $("#result").html('');

    /* Get from elements values */
    var values = $(this).serialize();

    /* Send the data using post and put the results in a div. */
    /* I am not aborting the previous request, because it's an
       asynchronous request, meaning once it's sent it's out
       there. But in case you want to abort it you can do it
       by abort(). jQuery Ajax methods return an XMLHttpRequest
       object, so you can just use abort(). */
       ajaxRequest= $.ajax({
            url: "test.php",
            type: "post",
            data: values
        });

    /*  Request can be aborted by ajaxRequest.abort() */

    ajaxRequest.done(function (response, textStatus, jqXHR){

         // Show successfully for submit message
         $("#result").html('Submitted successfully');
    });

    /* On failure of request this function will be called  */
    ajaxRequest.fail(function (){

        // Show error
        $("#result").html('There is error while submit');
    });

The .success(), .error(), and .complete() callbacks are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use .done(), .fail(), and .always() instead.

MDN: abort() . If the request has been sent already, this method will abort the request.

So we have successfully send an Ajax request, and now it's time to grab data to server.

PHP

As we make a POST request in an Ajax call (type: "post"), we can now grab data using either $_REQUEST or $_POST:

  $bar = $_POST['bar']

You can also see what you get in the POST request by simply either. BTW, make sure that $_POST is set. Otherwise you will get an error.

var_dump($_POST);
// Or
print_r($_POST);

And you are inserting a value into the database. Make sure you are sensitizing or escaping All requests (whether you made a GET or POST) properly before making the query. The best would be using prepared statements.

And if you want to return any data back to the page, you can do it by just echoing that data like below.

// 1. Without JSON
   echo "Hello, this is one"

// 2. By JSON. Then here is where I want to send a value back to the success of the Ajax below
echo json_encode(array('returned_val' => 'yoho'));

And then you can get it like:

 ajaxRequest.done(function (response){
    alert(response);
 });

There are a couple of shorthand methods. You can use the below code. It does the same work.

var ajaxRequest= $.post("test.php", values, function(data) {
  alert(data);
})
  .fail(function() {
    alert("error");
  })
  .always(function() {
    alert("finished");
});

If someone referring how to do the same feature (reading OTP using received SMS) on Xamarin Android like me :

1. Add this code to your AndroidManifest.xml file :

   <receiver android:name=".listener.BroadcastReveiverOTP">
   <intent-filter>
       <action android:name="android.provider.Telephony.SMS_RECEIVED" />
   </intent-filter>
   </receiver>
   <uses-permission android:name="android.permission.RECEIVE_SMS" />
   <uses-permission android:name="android.permission.BROADCAST_SMS" />
   <uses-permission android:name="android.permission.READ_SMS" />
   

2. Then create your BroadcastReveiver class in your Android Project.

   [BroadcastReceiver(Enabled = true)] [IntentFilter(new[] { "android.provider.Telephony.SMS_RECEIVED" }, Priority = (int)IntentFilterPriority.HighPriority)] 
   public class BroadcastReveiverOTP : BroadcastReceiver {
           public static readonly string INTENT_ACTION = "android.provider.Telephony.SMS_RECEIVED";
   
           protected string message, address = string.Empty;
   
           public override void OnReceive(Context context, Intent intent)
           {
               if (intent.HasExtra("pdus"))
               {
                   var smsArray = (Java.Lang.Object[])intent.Extras.Get("pdus");
                   foreach (var item in smsArray)
                   {
                       var sms = SmsMessage.CreateFromPdu((byte[])item);
                       address = sms.OriginatingAddress;
                       if (address.Equals("NotifyDEMO"))
                       {
                           message = sms.MessageBody;
                           string[] pin = message.Split(' ');
                           if (!string.IsNullOrWhiteSpace(pin[0]))
                           { 
                                   // NOTE : Here I'm passing received OTP to Portable Project using MessagingCenter. So I can display the OTP in the relevant entry field.
                                   MessagingCenter.Send<object, string>(this,MessengerKeys.OnBroadcastReceived, pin[0]);
                           }
                           }
                   }
               }
           }
   }
   

3. Register this BroadcastReceiver class in your MainActivity class on Android Project:

   public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity {
   
           // Initialize your class
           private BroadcastReveiverOTP _receiver = new BroadcastReveiverOTP ();
   
           protected override void OnCreate(Bundle bundle) { 
                   base.OnCreate(bundle);
   
                   global::Xamarin.Forms.Forms.Init(this, bundle);
                   LoadApplication(new App());
   
                   // Register your receiver :  RegisterReceiver(_receiver, new IntentFilter("android.provider.Telephony.SMS_RECEIVED"));
   
           }
   }
   

I followed the below Steps. It worked for me.

In Jenkins execute shell under Build, creating a file and trying to push that file from Jenkins workspace to GitHub.

Download Git Publisher Plugin and Configure as shown below snapshot.

Click on Save and Build. Now you can check your git repository whether the file was pushed successfully or not.

if only 1 row, you can use join

Select t1.Col1, t1.Col2, t1.Col3, t2.Col4, t2.Col5 from Table1 t1 join Table2 t2;

Try using null for the background ...

android:background="@null"

CSharpJExcel for reading Excel 97-2003 files (XLS), ExcelPackage for reading Excel 2007/2010 files (Office Open XML format, XLSX), and ExcelDataReader that seems to have the ability to handle both formats

Good luck!

Spaces in a folder name in your header search path can cause this problem. Make sure the folders in your project do not have spaces in their names.

This may be an answer (for spring boot 2) and a question at the same time. It seems that in spring boot 2 combined with spring security everything (means every route/antmatcher) is protected by default if you use an individual security mechanism extended from

WebSecurityConfigurerAdapter

If you don´t use an individual security mechanism, everything is as it was?

In older spring boot versions (1.5 and below) as Andy Wilkinson states in his above answer places like public/** or static/** are permitted by default.

So to sum this question/answer up - if you are using spring boot 2 with spring security and have an individual security mechanism you have to exclusivley permit access to static contents placed on any route. Like so:

@Configuration
public class SpringSecurityConfiguration extends WebSecurityConfigurerAdapter {

private final ThdAuthenticationProvider thdAuthenticationProvider;

private final ThdAuthenticationDetails thdAuthenticationDetails;

/**
 * Overloaded constructor.
 * Builds up the needed dependencies.
 *
 * @param thdAuthenticationProvider a given authentication provider
 * @param thdAuthenticationDetails  given authentication details
 */
@Autowired
public SpringSecurityConfiguration(@NonNull ThdAuthenticationProvider thdAuthenticationProvider,
                                   @NonNull ThdAuthenticationDetails thdAuthenticationDetails) {
    this.thdAuthenticationProvider = thdAuthenticationProvider;
    this.thdAuthenticationDetails = thdAuthenticationDetails;
}

/**
 * Creates the AuthenticationManager with the given values.
 *
 * @param auth the AuthenticationManagerBuilder
 */
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) {

    auth.authenticationProvider(thdAuthenticationProvider);
}

/**
 * Configures the http Security.
 *
 * @param http HttpSecurity
 * @throws Exception a given exception
 */
@Override
protected void configure(HttpSecurity http) throws Exception {

    http.authorizeRequests()
            .requestMatchers(PathRequest.toStaticResources().atCommonLocations()).permitAll()
            .antMatchers("/management/**").hasAnyAuthority(Role.Role_Engineer.getValue(),
            Role.Role_Admin.getValue())
            .antMatchers("/settings/**").hasAnyAuthority(Role.Role_Engineer.getValue(),
            Role.Role_Admin.getValue())

            .anyRequest()
            .fullyAuthenticated()
            .and()
            .formLogin()
            .authenticationDetailsSource(thdAuthenticationDetails)
            .loginPage("/login").permitAll()
            .defaultSuccessUrl("/bundle/index", true)
            .failureUrl("/denied")
            .and()
            .logout()
            .invalidateHttpSession(true)
            .logoutSuccessUrl("/login")
            .logoutUrl("/logout")
            .and()
            .exceptionHandling()
            .accessDeniedHandler(new CustomAccessDeniedHandler());
}

}

Please mind this line of code, which is new:

.requestMatchers(PathRequest.toStaticResources().atCommonLocations()).permitAll()

If you use spring boot 1.5 and below you don´t need to permit these locations (static/public/webjars etc.) explicitly.

Here is the official note, what has changed in the new security framework as to old versions of itself:

Security changes in Spring Boot 2.0 M4

I hope this helps someone. Thank you! Have a nice day!

While the answers explaining the exact differences are fine, I want to show how the relational algebra is transformed to SQL and what the actual value of the 3 concepts is.

The key concept in your question is the idea of a join. To understand a join you need to understand a Cartesian Product (the example is based on SQL where the equivalent is called a cross join as onedaywhen points out);

This isn't very useful in practice. Consider this example.

Product(PName, Price)
====================
Laptop,   1500
Car,      20000
Airplane, 3000000


Component(PName, CName, Cost)
=============================
Laptop, CPU,    500
Laptop, hdd,    300
Laptop, case,   700
Car,    wheels, 1000

The Cartesian product Product x Component will be - bellow or sql fiddle. You can see there are 12 rows = 3 x 4. Obviously, rows like "Laptop" with "wheels" have no meaning, this is why in practice the Cartesian product is rarely used.

|    PNAME |   PRICE |  CNAME | COST |
--------------------------------------
|   Laptop |    1500 |    CPU |  500 |
|   Laptop |    1500 |    hdd |  300 |
|   Laptop |    1500 |   case |  700 |
|   Laptop |    1500 | wheels | 1000 |
|      Car |   20000 |    CPU |  500 |
|      Car |   20000 |    hdd |  300 |
|      Car |   20000 |   case |  700 |
|      Car |   20000 | wheels | 1000 |
| Airplane | 3000000 |    CPU |  500 |
| Airplane | 3000000 |    hdd |  300 |
| Airplane | 3000000 |   case |  700 |
| Airplane | 3000000 | wheels | 1000 |

JOINs are here to add more value to these products. What we really want is to "join" the product with its associated components, because each component belongs to a product. The way to do this is with a join:

Product JOIN Component ON Pname

The associated SQL query would be like this (you can play with all the examples here)

SELECT *
FROM Product
JOIN Component
  ON Product.Pname = Component.Pname

and the result:

|  PNAME | PRICE |  CNAME | COST |
----------------------------------
| Laptop |  1500 |    CPU |  500 |
| Laptop |  1500 |    hdd |  300 |
| Laptop |  1500 |   case |  700 |
|    Car | 20000 | wheels | 1000 |

Notice that the result has only 4 rows, because the Laptop has 3 components, the Car has 1 and the Airplane none. This is much more useful.

Getting back to your questions, all the joins you ask about are variations of the JOIN I just showed:

Natural Join = the join (the ON clause) is made on all columns with the same name; it removes duplicate columns from the result, as opposed to all other joins; most DBMS (database systems created by various vendors such as Microsoft's SQL Server, Oracle's MySQL etc. ) don't even bother supporting this, it is just bad practice (or purposely chose not to implement it). Imagine that a developer comes and changes the name of the second column in Product from Price to Cost. Then all the natural joins would be done on PName AND on Cost, resulting in 0 rows since no numbers match.

Theta Join = this is the general join everybody uses because it allows you to specify the condition (the ON clause in SQL). You can join on pretty much any condition you like, for example on Products that have the first 2 letters similar, or that have a different price. In practice, this is rarely the case - in 95% of the cases you will join on an equality condition, which leads us to:

Equi Join = the most common one used in practice. The example above is an equi join. Databases are optimized for this type of joins! The oposite of an equi join is a non-equi join, i.e. when you join on a condition other than "=". Databases are not optimized for this! Both of them are subsets of the general theta join. The natural join is also a theta join but the condition (the theta) is implicit.

Source of information: university + certified SQL Server developer + recently completed the MOO "Introduction to databases" from Stanford so I dare say I have relational algebra fresh in mind.

None of these answers ended up working for my Git credential issue. Here is what did work if anyone needs it (I'm using Git 1.9 on Windows 8.1).

To update your credentials, go to Control Panel → Credential Manager → Generic Credentials. Find the credentials related to your Git account and edit them to use the updated password.

Reference: How to update your Git credentials on Windows

Note that to use the Windows Credential Manager for Git you need to configure the credential helper like so:

git config --global credential.helper wincred

If you have multiple GitHub accounts that you use for different repositories, then you should configure credentials to use the full repository path (rather than just the domain, which is the default):

git config --global credential.useHttpPath true

Update: AppCompat support

Other answers suspecting if android:tint will work on only 21+ devices only, AppCompat(v23.2.0 and above) now provides a backward compatible handling of tint attribute.

So, the course of action would be to use AppCompatImageView and app:srcCompat(in AppCompat namespace) instead of android:src(Android namespace).

Here is an example(AndroidX: This is androidx.appcompat.widget.AppCompatImageView ;)):

<android.support.v7.widget.AppCompatImageView
        android:id="@+id/credits_material_icon"
        android:layout_width="20dp"
        android:layout_height="20dp"
        android:layout_marginBottom="8dp"
        android:layout_marginLeft="16dp"
        android:layout_marginStart="16dp"
        android:scaleType="fitCenter"
        android:tint="#ffd2ee"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:srcCompat="@drawable/ic_dollar_coin_stack" />

And don't forget to enable vector drawable support in gradle:

vectorDrawables.useSupportLibrary = true 

There are two possible reasons for that problem:

1. did not install aclocal.
   solution:install libtool

   • For ubuntu: sudo apt-get install libtool
   • For centos: sudo yum install libtool

2. the path to LIBTOOL.m4 is error.
   solution:

   1. use aclocal --print-ac-dir to check current path to aclocal.(It's usually should be "/usr/share/aclocal" or "/usr/share/aclocal")
   2. Then check if there are *.m4 files.
   3. If not, cp corresponding *.m4 files to this path.( Maybe cp /usr/share/aclocal/*.m4 /usr/local/share/aclocal/ or cp /usr/local/share/aclocal/*.m4 /usr/share/aclocal/)

Hope it helps

The following works lists all *.txt files in the current dir, except those that begin with a number.

This works in bash, dash, zsh and all other POSIX compatible shells.

for FILE in /some/dir/*.txt; do    # for each *.txt file
    case "${FILE##*/}" in          #   if file basename...
        [0-9]*) continue ;;        #   starts with digit: skip
    esac
    ## otherwise, do stuff with $FILE here
done

1. In line one the pattern /some/dir/*.txt will cause the for loop to iterate over all files in /some/dir whose name end with .txt.

2. In line two a case statement is used to weed out undesired files. – The ${FILE##*/} expression strips off any leading dir name component from the filename (here /some/dir/) so that patters can match against only the basename of the file. (If you're only weeding out filenames based on suffixes, you can shorten this to $FILE instead.)

3. In line three, all files matching the case pattern [0-9]*) line will be skipped (the continue statement jumps to the next iteration of the for loop). – If you want to you can do something more interesting here, e.g. like skipping all files which do not start with a letter (a–z) using [!a-z]*, or you could use multiple patterns to skip several kinds of filenames e.g. [0-9]*|*.bak to skip files both .bak files, and files which does not start with a number.

Try this:

<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/rel_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<ImageView
    android:id="@+id/ImageView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src=//source of image />

<TextView
    android:id="@+id/ImageViewText"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@id/ImageView"
    android:layout_alignTop="@id/ImageView"
    android:layout_alignRight="@id/ImageView"
    android:layout_alignBottom="@id/ImageView"
    android:text=//u r text here
    android:gravity="center"
    />

Hope this could help you.

the abs function is when the Strings are not the same length so the legth of the result will be the same as the min lenght of the two String a and b

public String xor(String a, String b){
    StringBuilder sb = new StringBuilder();
    for(int k=0; k < a.length(); k++)
       sb.append((a.charAt(k) ^ b.charAt(k + (Math.abs(a.length() - b.length()))))) ;
       return sb.toString();
}

You can do it without having to create a real Hibernate mapping. Try this:

SELECT * FROM Employee e, Team t WHERE e.Id_team=t.Id_team

you may use template reference variable and send to a method

html

<input #variable type="file" placeholder="File Name" name="filename" (change)="onChange($event, variable);">

component

onChange(event: any, element): void {
    // codes
    element.value = '';
  }

If you don't create a root window, Tkinter will create one for you when you try to create any other widget. Thus, in your __init__, because you haven't yet created a root window when you initialize the frame, Tkinter will create one for you. Then, you call make_widgets which creates a second root window. That is why you are seeing two windows.

A well-written Tkinter program should always explicitly create a root window before creating any other widgets.

When you modify your code to explicitly create the root window, you'll end up with one window with the expected title.

Example:

from tkinter import Tk, Button, Frame, Entry, END

class ABC(Frame):
    def __init__(self,parent=None):
        Frame.__init__(self,parent)
        self.parent = parent
        self.pack()
        self.make_widgets()

    def make_widgets(self):
        # don't assume that self.parent is a root window.
        # instead, call `winfo_toplevel to get the root window
        self.winfo_toplevel().title("Simple Prog")

        # this adds something to the frame, otherwise the default
        # size of the window will be very small
        label = Entry(self)
        label.pack(side="top", fill="x")

root = Tk()
abc = ABC(root)
root.mainloop()

Also note the use of self.make_widgets() rather than ABC.make_widgets(self). While both end up doing the same thing, the former is the proper way to call the function.

    void *ptr = ((uintptr_t)mem+15) & ~ (uintptr_t)0x0F;
    memset_16aligned(ptr, 0, 1024);
    free(mem);
}

Explanation as requested

The first step is to allocate enough spare space, just in case. Since the memory must be 16-byte aligned (meaning that the leading byte address needs to be a multiple of 16), adding 16 extra bytes guarantees that we have enough space. Somewhere in the first 16 bytes, there is a 16-byte aligned pointer. (Note that malloc() is supposed to return a pointer that is sufficiently well aligned for any purpose. However, the meaning of 'any' is primarily for things like basic types — long, double, long double, long long, and pointers to objects and pointers to functions. When you are doing more specialized things, like playing with graphics systems, they can need more stringent alignment than the rest of the system — hence questions and answers like this.)

The next step is to convert the void pointer to a char pointer; GCC notwithstanding, you are not supposed to do pointer arithmetic on void pointers (and GCC has warning options to tell you when you abuse it). Then add 16 to the start pointer. Suppose malloc() returned you an impossibly badly aligned pointer: 0x800001. Adding the 16 gives 0x800011. Now I want to round down to the 16-byte boundary — so I want to reset the last 4 bits to 0. 0x0F has the last 4 bits set to one; therefore, ~0x0F has all bits set to one except the last four. Anding that with 0x800011 gives 0x800010. You can iterate over the other offsets and see that the same arithmetic works.

The last step, free(), is easy: you always, and only, return to free() a value that one of malloc(), calloc() or realloc() returned to you — anything else is a disaster. You correctly provided mem to hold that value — thank you. The free releases it.

Finally, if you know about the internals of your system's malloc package, you could guess that it might well return 16-byte aligned data (or it might be 8-byte aligned). If it was 16-byte aligned, then you'd not need to dink with the values. However, this is dodgy and non-portable — other malloc packages have different minimum alignments, and therefore assuming one thing when it does something different would lead to core dumps. Within broad limits, this solution is portable.

Someone else mentioned posix_memalign() as another way to get the aligned memory; that isn't available everywhere, but could often be implemented using this as a basis. Note that it was convenient that the alignment was a power of 2; other alignments are messier.

One more comment — this code does not check that the allocation succeeded.

Amendment

Windows Programmer pointed out that you can't do bit mask operations on pointers, and, indeed, GCC (3.4.6 and 4.3.1 tested) does complain like that. So, an amended version of the basic code — converted into a main program, follows. I've also taken the liberty of adding just 15 instead of 16, as has been pointed out. I'm using uintptr_t since C99 has been around long enough to be accessible on most platforms. If it wasn't for the use of PRIXPTR in the printf() statements, it would be sufficient to #include <stdint.h> instead of using #include <inttypes.h>. [This code includes the fix pointed out by C.R., which was reiterating a point first made by Bill K a number of years ago, which I managed to overlook until now.]

#include <assert.h>
#include <inttypes.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

static void memset_16aligned(void *space, char byte, size_t nbytes)
{
    assert((nbytes & 0x0F) == 0);
    assert(((uintptr_t)space & 0x0F) == 0);
    memset(space, byte, nbytes);  // Not a custom implementation of memset()
}

int main(void)
{
    void *mem = malloc(1024+15);
    void *ptr = (void *)(((uintptr_t)mem+15) & ~ (uintptr_t)0x0F);
    printf("0x%08" PRIXPTR ", 0x%08" PRIXPTR "\n", (uintptr_t)mem, (uintptr_t)ptr);
    memset_16aligned(ptr, 0, 1024);
    free(mem);
    return(0);
}

And here is a marginally more generalized version, which will work for sizes which are a power of 2:

#include <assert.h>
#include <inttypes.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

static void memset_16aligned(void *space, char byte, size_t nbytes)
{
    assert((nbytes & 0x0F) == 0);
    assert(((uintptr_t)space & 0x0F) == 0);
    memset(space, byte, nbytes);  // Not a custom implementation of memset()
}

static void test_mask(size_t align)
{
    uintptr_t mask = ~(uintptr_t)(align - 1);
    void *mem = malloc(1024+align-1);
    void *ptr = (void *)(((uintptr_t)mem+align-1) & mask);
    assert((align & (align - 1)) == 0);
    printf("0x%08" PRIXPTR ", 0x%08" PRIXPTR "\n", (uintptr_t)mem, (uintptr_t)ptr);
    memset_16aligned(ptr, 0, 1024);
    free(mem);
}

int main(void)
{
    test_mask(16);
    test_mask(32);
    test_mask(64);
    test_mask(128);
    return(0);
}

To convert test_mask() into a general purpose allocation function, the single return value from the allocator would have to encode the release address, as several people have indicated in their answers.

Problems with interviewers

Uri commented: Maybe I am having [a] reading comprehension problem this morning, but if the interview question specifically says: "How would you allocate 1024 bytes of memory" and you clearly allocate more than that. Wouldn't that be an automatic failure from the interviewer?

My response won't fit into a 300-character comment...

It depends, I suppose. I think most people (including me) took the question to mean "How would you allocate a space in which 1024 bytes of data can be stored, and where the base address is a multiple of 16 bytes". If the interviewer really meant how can you allocate 1024 bytes (only) and have it 16-byte aligned, then the options are more limited.

• Clearly, one possibility is to allocate 1024 bytes and then give that address the 'alignment treatment'; the problem with that approach is that the actual available space is not properly determinate (the usable space is between 1008 and 1024 bytes, but there wasn't a mechanism available to specify which size), which renders it less than useful.
• Another possibility is that you are expected to write a full memory allocator and ensure that the 1024-byte block you return is appropriately aligned. If that is the case, you probably end up doing an operation fairly similar to what the proposed solution did, but you hide it inside the allocator.

However, if the interviewer expected either of those responses, I'd expect them to recognize that this solution answers a closely related question, and then to reframe their question to point the conversation in the correct direction. (Further, if the interviewer got really stroppy, then I wouldn't want the job; if the answer to an insufficiently precise requirement is shot down in flames without correction, then the interviewer is not someone for whom it is safe to work.)

The world moves on

The title of the question has changed recently. It was Solve the memory alignment in C interview question that stumped me. The revised title (How to allocate aligned memory only using the standard library?) demands a slightly revised answer — this addendum provides it.

C11 (ISO/IEC 9899:2011) added function aligned_alloc():

7.22.3.1 The aligned_alloc function

Synopsis

#include <stdlib.h>
void *aligned_alloc(size_t alignment, size_t size);

Description
The aligned_alloc function allocates space for an object whose alignment is specified by alignment, whose size is specified by size, and whose value is indeterminate. The value of alignment shall be a valid alignment supported by the implementation and the value of size shall be an integral multiple of alignment.

Returns
The aligned_alloc function returns either a null pointer or a pointer to the allocated space.

And POSIX defines posix_memalign():

#include <stdlib.h>

int posix_memalign(void **memptr, size_t alignment, size_t size);

DESCRIPTION

The posix_memalign() function shall allocate size bytes aligned on a boundary specified by alignment, and shall return a pointer to the allocated memory in memptr. The value of alignment shall be a power of two multiple of sizeof(void *).

Upon successful completion, the value pointed to by memptr shall be a multiple of alignment.

If the size of the space requested is 0, the behavior is implementation-defined; the value returned in memptr shall be either a null pointer or a unique pointer.

The free() function shall deallocate memory that has previously been allocated by posix_memalign().

RETURN VALUE

Upon successful completion, posix_memalign() shall return zero; otherwise, an error number shall be returned to indicate the error.

Either or both of these could be used to answer the question now, but only the POSIX function was an option when the question was originally answered.

Behind the scenes, the new aligned memory function do much the same job as outlined in the question, except they have the ability to force the alignment more easily, and keep track of the start of the aligned memory internally so that the code doesn't have to deal with specially — it just frees the memory returned by the allocation function that was used.

Here's a good reference on the different formatting you can use with regard to the date:

http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.infocenter.dc38151.1510/html/iqrefbb/Convert.htm

If you're in netbeans you can right click in the test method and click "Run Focused Test Method".

In C, a "stream" is an abstraction; from the program's perspective it is simply a producer (input stream) or consumer (output stream) of bytes. It can correspond to a file on disk, to a pipe, to your terminal, or to some other device such as a printer or tty. The FILE type contains information about the stream. Normally, you don't mess with a FILE object's contents directly, you just pass a pointer to it to the various I/O routines.

There are three standard streams: stdin is a pointer to the standard input stream, stdout is a pointer to the standard output stream, and stderr is a pointer to the standard error output stream. In an interactive session, the three usually refer to your console, although you can redirect them to point to other files or devices:

$ myprog < inputfile.dat > output.txt 2> errors.txt

In this example, stdin now points to inputfile.dat, stdout points to output.txt, and stderr points to errors.txt.

fprintf writes formatted text to the output stream you specify.

printf is equivalent to writing fprintf(stdout, ...) and writes formatted text to wherever the standard output stream is currently pointing.

sprintf writes formatted text to an array of char, as opposed to a stream.

You can also use translate(). If the third argument is too short, the corresponding characters from the second argument are deleted. Unlike regexp_replace() you don't need to worry about special characters. Source code.

            //element will not Hide on click some specific control inside document
            $('.control-1').on('click', function (e) {

Unix cp doesn't 'support both directories and files':

betelgeuse:tmp james$ cp source/ dest/
cp: source/ is a directory (not copied).

To make cp copy a directory, you have to manually tell cp that it's a directory, by using the '-r' flag.

There is some disconnect here though - cp -r when passed a filename as the source will happily copy just the single file; copytree won't.

Mac OS X doesn't have apt-get. There is a package manager called Homebrew that is used instead.

This command would be:

brew install python

Use Homebrew to install packages that you would otherwise use apt-get for.

The page I linked to has an up-to-date way of installing homebrew, but at present, you can install Homebrew as follows:

Type the following in your Mac OS X terminal:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

After that, usage of Homebrew is brew install <package>.

One of the prerequisites for Homebrew are the XCode command line tools.

1. Install XCode from the App Store.
2. Follow the directions in this Stack Overflow answer to install the XCode Command Line Tools.

Background

A package manager (like apt-get or brew) just gives your system an easy and automated way to install packages or libraries. Different systems use different programs. apt and its derivatives are used on Debian based linux systems. Red Hat-ish Linux systems use rpm (or at least they did many, many, years ago). yum is also a package manager for RedHat based systems.

Alpine based systems use apk.

Warning

As of 25 April 2016, homebrew opts the user in to sending analytics by default. This can be opted out of in two ways:

Setting an environment variable:

1. Open your favorite environment variable editor.
2. Set the following: HOMEBREW_NO_ANALYTICS=1 in whereever you keep your environment variables (typically something like ~/.bash_profile)
3. Close the file, and either restart the terminal or source ~/.bash_profile.

Running the following command:

brew analytics off

the analytics status can then be checked with the command:

brew analytics

        #        #  This is called "self" by convention, but could be any name you want.
        #^ double underscore (dunder) methods are usually special.  This one 
        #  gets called immediately after a new instance is created.

        self.variable = "Foo" #instance attribute.

    def method(self, arg1, arg2):
        #This method has arguments.  You would call it like this:  instance.method(1, 2)
        print "in method (args):", arg1, arg2
        print "in method (attributes):", self.variable, self.bar


a = Foo() # this calls __init__ (indirectly), output:
                 # Foo bar
                 # Foo  Bar is now Baz
print a.variable # Foo

The definitive guide on how to use static, class or abstract methods in Python is one good link for this topic, and summary it as following.

@staticmethod function is nothing more than a function defined inside a class. It is callable without instantiating the class first. It’s definition is immutable via inheritance.

• Python does not have to instantiate a bound-method for object.
• It eases the readability of the code, and it does not depend on the state of object itself;

@classmethod function also callable without instantiating the class, but its definition follows Sub class, not Parent class, via inheritance, can be overridden by subclass. That’s because the first argument for @classmethod function must always be cls (class).

• Factory methods, that are used to create an instance for a class using for example some sort of pre-processing.
• Static methods calling static methods: if you split a static methods in several static methods, you shouldn't hard-code the class name but use class methods

A keystore needs a keystore file. The KeyStore class needs a FileInputStream. But if you supply null (instead of FileInputStream instance) an empty keystore will be loaded. Once you create a keystore, you can verify its integrity using keytool.

Following code creates an empty keystore with empty password

  KeyStore ks2 = KeyStore.getInstance("jks");
  ks2.load(null,"".toCharArray());
  FileOutputStream out = new FileOutputStream("C:\\mykeytore.keystore");
  ks2.store(out, "".toCharArray());

Once you have the keystore, importing certificate is very easy. Checkout this link for the sample code.

I also had this problem recently. Working with a new client, trying to get a an old web forms app running from Visual Studio, with IISExpress using Windows Authentication. For me, the web.config was correctly configured

However, the IISExpress.config settings file had:

<windowsAuthentication enabled="false">

The user account the developer was logged in was very new, so unlikely it had been edited. Simple fix it turned out, change this to enabled=true and it all ran as it should then.
