this for the now swift 5.0 and newst

var secondsRemaining = 60


Timer.scheduledTimer(timeInterval: 1.0, target: self, selector: #selector(updateCounter), userInfo: nil, repeats: true)
}
@objc func updateCounter(){
    if secondsRemaining > 0 {
    print("\(secondsRemaining) seconds.")
    secondsRemaining -= 1
            }
        }

Swift itself doesn't use selectors — several design patterns that in Objective-C make use of selectors work differently in Swift. (For example, use optional chaining on protocol types or is/as tests instead of respondsToSelector:, and use closures wherever you can instead of performSelector: for better type/memory safety.)

But there are still a number of important ObjC-based APIs that use selectors, including timers and the target/action pattern. Swift provides the Selector type for working with these. (Swift automatically uses this in place of ObjC's SEL type.)

In Swift 2.2 (Xcode 7.3) and later (including Swift 3 / Xcode 8 and Swift 4 / Xcode 9):

You can construct a Selector from a Swift function type using the #selector expression.

let timer = Timer(timeInterval: 1, target: object,
                  selector: #selector(MyClass.test),
                  userInfo: nil, repeats: false)
button.addTarget(object, action: #selector(MyClass.buttonTapped),
                 for: .touchUpInside)
view.perform(#selector(UIView.insertSubview(_:aboveSubview:)),
             with: button, with: otherButton)

The great thing about this approach? A function reference is checked by the Swift compiler, so you can use the #selector expression only with class/method pairs that actually exist and are eligible for use as selectors (see "Selector availability" below). You're also free to make your function reference only as specific as you need, as per the Swift 2.2+ rules for function-type naming.

(This is actually an improvement over ObjC's @selector() directive, because the compiler's -Wundeclared-selector check verifies only that the named selector exists. The Swift function reference you pass to #selector checks existence, membership in a class, and type signature.)

There are a couple of extra caveats for the function references you pass to the #selector expression:

• Multiple functions with the same base name can be differentiated by their parameter labels using the aforementioned syntax for function references (e.g. insertSubview(_:at:) vs insertSubview(_:aboveSubview:)). But if a function has no parameters, the only way to disambiguate it is to use an as cast with the function's type signature (e.g. foo as () -> () vs foo(_:)).
• There's a special syntax for property getter/setter pairs in Swift 3.0+. For example, given a var foo: Int, you can use #selector(getter: MyClass.foo) or #selector(setter: MyClass.foo).

General notes:

Cases where #selector doesn't work, and naming: Sometimes you don't have a function reference to make a selector with (for example, with methods dynamically registered in the ObjC runtime). In that case, you can construct a Selector from a string: e.g. Selector("dynamicMethod:") — though you lose the compiler's validity checking. When you do that, you need to follow ObjC naming rules, including colons (:) for each parameter.

Selector availability: The method referenced by the selector must be exposed to the ObjC runtime. In Swift 4, every method exposed to ObjC must have its declaration prefaced with the @objc attribute. (In previous versions you got that attribute for free in some cases, but now you have to explicitly declare it.)

Remember that private symbols aren't exposed to the runtime, too — your method needs to have at least internal visibility.

Key paths: These are related to but not quite the same as selectors. There's a special syntax for these in Swift 3, too: e.g. chris.valueForKeyPath(#keyPath(Person.friends.firstName)). See SE-0062 for details. And even more KeyPath stuff in Swift 4, so make sure you're using the right KeyPath-based API instead of selectors if appropriate.

You can read more about selectors under Interacting with Objective-C APIs in Using Swift with Cocoa and Objective-C.

^{Note: Before Swift 2.2, Selector conformed to StringLiteralConvertible, so you might find old code where bare strings are passed to APIs that take selectors. You'll want to run "Convert to Current Swift Syntax" in Xcode to get those using #selector.}

NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:60 target:self selector:@selector(timerCalled) userInfo:nil repeats:NO];

-(void)timerCalled
{
     NSLog(@"Timer Called");
     // Your Code
}

The solution you will use really depends on how long you need to wait between each execution of your function.

If you are waiting for longer than 10 minutes, I would suggest using AlarmManager.

// Some time when you want to run
Date when = new Date(System.currentTimeMillis());

try {
    Intent someIntent = new Intent(someContext, MyReceiver.class); // intent to be launched

    // Note: this could be getActivity if you want to launch an activity
    PendingIntent pendingIntent = PendingIntent.getBroadcast(
        context,
        0, // id (optional)
        someIntent, // intent to launch
        PendingIntent.FLAG_CANCEL_CURRENT // PendingIntent flag
    );

    AlarmManager alarms = (AlarmManager) context.getSystemService(
        Context.ALARM_SERVICE
    );

    alarms.setRepeating(
        AlarmManager.RTC_WAKEUP,
        when.getTime(),
        AlarmManager.INTERVAL_FIFTEEN_MINUTES,
        pendingIntent
    );
} catch(Exception e) {
    e.printStackTrace();
}

Once you have broadcasted the above Intent, you can receive your Intent by implementing a BroadcastReceiver. Note that this will need to be registered either in your application manifest or via the context.registerReceiver(receiver, intentFilter); method. For more information on BroadcastReceiver's please refer to the official documentation..

public class MyReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent)
    {
        System.out.println("MyReceiver: here!") // Do your work here
    }
}

If you are waiting for shorter than 10 minutes then I would suggest using a Handler.

final Handler handler = new Handler();
final int delay = 1000; // 1000 milliseconds == 1 second

handler.postDelayed(new Runnable() {
    public void run() {
        System.out.println("myHandler: here!"); // Do your work here
        handler.postDelayed(this, delay);
    }
}, delay);

This will work:

override func viewDidLoad() {
    super.viewDidLoad()
    // Swift block syntax (iOS 10+)
    let timer = Timer(timeInterval: 0.4, repeats: true) { _ in print("Done!") }
    // Swift >=3 selector syntax
    let timer = Timer.scheduledTimer(timeInterval: 0.4, target: self, selector: #selector(self.update), userInfo: nil, repeats: true)
    // Swift 2.2 selector syntax
    let timer = NSTimer.scheduledTimerWithTimeInterval(0.4, target: self, selector: #selector(MyClass.update), userInfo: nil, repeats: true)
    // Swift <2.2 selector syntax
    let timer = NSTimer.scheduledTimerWithTimeInterval(0.4, target: self, selector: "update", userInfo: nil, repeats: true)
}

// must be internal or public. 
@objc func update() {
    // Something cool
}

For Swift 4, the method of which you want to get the selector must be exposed to Objective-C, thus @objc attribute must be added to the method declaration.

replace isn't available for XSLT 1.0.

Codesling has a template for string-replace you can use as a substitute for the function:

<xsl:template name="string-replace-all">
    <xsl:param name="text" />
    <xsl:param name="replace" />
    <xsl:param name="by" />
    <xsl:choose>
        <xsl:when test="$text = '' or $replace = ''or not($replace)" >
            <!-- Prevent this routine from hanging -->
            <xsl:value-of select="$text" />
        </xsl:when>
        <xsl:when test="contains($text, $replace)">
            <xsl:value-of select="substring-before($text,$replace)" />
            <xsl:value-of select="$by" />
            <xsl:call-template name="string-replace-all">
                <xsl:with-param name="text" select="substring-after($text,$replace)" />
                <xsl:with-param name="replace" select="$replace" />
                <xsl:with-param name="by" select="$by" />
            </xsl:call-template>
        </xsl:when>
        <xsl:otherwise>
            <xsl:value-of select="$text" />
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>

invoked as:

<xsl:variable name="newtext">
    <xsl:call-template name="string-replace-all">
        <xsl:with-param name="text" select="$text" />
        <xsl:with-param name="replace" select="a" />
        <xsl:with-param name="by" select="b" />
    </xsl:call-template>
</xsl:variable>

On the other hand, if you literally only need to replace one character with another, you can call translate which has a similar signature. Something like this should work fine:

<xsl:variable name="newtext" select="translate($text,'a','b')"/>

Also, note, in this example, I changed the variable name to "newtext", in XSLT variables are immutable, so you can't do the equivalent of $foo = $foo like you had in your original code.

On windows 10 (client) you can also script this using

Enable-WindowsOptionalFeature -Online -NoRestart -FeatureName WCF-HTTP-Activation45 -All

Note that this is a different command from the server skus

>>> print "%r, %r" % (True, False)
True, False

This is not specific to boolean values - %r calls the __repr__ method on the argument. %s (for str) should also work.

Even if you don't control the server, you can still see the error messages by adding the following line to the Web.config file in your project (bewlow <system.web>):

<customErrors mode="off" />

you can use PATTERN:

<input class="form-control" minlength="1" pattern="[0-9]*" [(ngModel)]="value" #name="ngModel">

<div *ngIf="name.invalid && (name.dirty || name.touched)" class="text-danger">
  <div *ngIf="name.errors?.pattern">Is not a number</div>
</div>

The documentation is your friend, NSString supports a call substringWithRange that can shorten the string that you have an return the shortened String. You cannot modify an instance of NSString it is immutable. If you have an NSMutableString is has a method called deleteCharactersInRange that can modify the string in place

...
NSRange r;
r.location = 0;
r.size = [mutable length]-1;
NSString* shorted = [stringValue substringWithRange:r];
...

Finally got the correct thing

echo "Hello, world!" | tr -d '\n' | xxd -ps -c 200

The standard Ubuntu install seems to put the various Java versions in /usr/lib/jvm. The javac, java you find in your path will softlink to this.

There's no issue with installing your own Java version anywhere you like, as long as you set the JAVA_HOME environment variable and make sure to have the new Java bin on your path.

A simple way to do this is to have the Java home exist as a softlink, so that if you want to upgrade or switch versions you only have to change the directory that this points to - e.g.:

/usr/bin/java --> /opt/jdk/bin/java,

/opt/jdk --> /opt/jdk1.6.011

Yes, You can do it in a simple way. See below code of lines.

URL - http://localhost:8080/get/request/multiple/param/by/map?name='abc' & id='123'

 @GetMapping(path = "/get/request/header/by/map")
    public ResponseEntity<String> getRequestParamInMap(@RequestParam Map<String,String> map){
        // Do your business here 
        return new ResponseEntity<String>(map.toString(),HttpStatus.OK);
    } 

String s = "String="

String[] str = s.split("="); //now str[0] is "hello" and str[1] is "goodmorning,2,1"

add this string

Two generic ways to do the same thing... I'm not aware of any specific open solutions to do this, but it'd be rather trivial to do.

You could write a daily or weekly cron/jenkins job to scrape the previous time period's email from the archive looking for your keyworkds/combinations. Sending a batch digest with what it finds, if anything.

But personally, I'd Setup a specific email account to subscribe to the various security lists you're interested in. Add a simple automated script to parse the new emails for various keywords or combinations of keywords, when it finds a match forward that email on to you/your team. Just be sure to keep the keywords list updated with new products you're using.

You could even do this with a gmail account and custom rules, which is what I currently do, but I have setup an internal inbox in the past with a simple python script to forward emails that were of interest.

public static void main(String[] args) {
    String test = "something hear - to - find some to or tows";
    System.out.println("1.result: " + contains("- to -( \\w+) som", test, null));
    System.out.println("2.result: " + contains("- to -( \\w+) som", test, 5));
}
static boolean contains(String pattern, String text, Integer fromIndex){
    if(fromIndex != null && fromIndex < text.length())
        return Pattern.compile(pattern).matcher(text).find();

    return Pattern.compile(pattern).matcher(text).find();
}

1.result: true

2.result: true

You can try this code:

USE AdventureWorks2012;
GO
SET STATISTICS TIME ON;
GO
SELECT ProductID, StartDate, EndDate, StandardCost 
FROM Production.ProductCostHistory
WHERE StandardCost < 500.00;
GO
SET STATISTICS TIME OFF;
GO

To compare character you use the == operator:

if (c == ' ')

First I'd check to verify it is listening on the IPs you expect it to be:

netstat -nlpt | grep 6379

Depending on how you start/stop you may not have actually restarted the instance when you thought you had. The netstat will tell you if it is listening where you think it is. If not, restart it and be sure it restarts. If it restarts and still is not listening where you expect, check your config file just to be sure.

After establishing it is listening where you expect it to, from a remote node which should have access try:

redis-cli -h REMOTE.HOST ping

You could also try that from the local host but use the IP you expect it to be listening on instead of a hostname or localhost. You should see it PONG in response in both cases.

If not, your firewall(s) is/are blocking you. This would be either the local IPTables or possibly a firewall in between the nodes. You could add a logging statement to your IPtables configuration to log connections over 6379 to see what is happening. Also, trying he redis ping from local and non-local to the same IP should be illustrative. If it responds locally but not remotely, I'd lean toward an intervening firewall depending on the complexity of your on-node IP Tables rules.

If you are on Linux/Unix have a look at mbstowcs() and wcstombs() defined in GNU C (from ISO C 90).

• mbs stand for "Multi Bytes String" and is basically the usual zero terminated C string.

• wcs stand for Wide Char String and is an array of wchar_t.

For more background details on wide chars have a look at glibc documentation here.

Just select the text you want to change, right click and select UPPERCASE or lowercase depending on what you want.

If destroy() and clear() is not working (just like what i had experience) you can use jquery to remove the canvas and append it again.

    $('#chartAmazon').remove();
    $('#chartBar').append('<canvas id="chartAmazon"></canvas>');

    var ctxAmazon = $("#chartAmazon").get(0).getContext("2d");
      var AmazonChart = new Chart(ctxAmazon, {
        type: 'doughnut',
        data: dataAmazon,
        options: optionsA
    });

You've gotten some answers, and most of them are correct, but miss what (I think) is probably the point here.

My guess is that you have a makefile you're trying to use to create an executable. In case you're not familiar with them, makefiles list dependencies between files. For a really simple case, it might have something like:

myprogram.exe: myprogram.o
    $(CC) -o myprogram.exe myprogram.o

myprogram.o: myprogram.cpp
    $(CC) -c myprogram.cpp

The first line says that myprogram.exe depends on myprogram.o. The second line tells how to create myprogram.exe from myprogram.o. The third and fourth lines say myprogram.o depends on myprogram.cpp, and how to create myprogram.o from myprogram.cpp` respectively.

My guess is that in your case, you have a makefile like the one above that was created for gcc. The problem you're running into is that you're using it with MS VC instead of gcc. As it happens, MS VC uses ".obj" as the extension for its object files instead of ".o".

That means when make (or its equivalent built into the IDE in your case) tries to build the program, it looks at those lines to try to figure out how to build myprogram.exe. To do that, it sees that it needs to build myprogram.o, so it looks for the rule that tells it how to build myprogram.o. That says it should compile the .cpp file, so it does that.

Then things break down -- the VC++ compiler produces myprogram.obj instead of myprogram.o as the object file, so when it tries to go to the next step to produce myprogram.exe from myprogram.o, it finds that its attempt at creating myprogram.o simply failed. It did what the rule said to do, but that didn't produce myprogram.o as promised. It doesn't know what to do, so it quits and give you an error message.

The cure for that specific problem is probably pretty simple: edit the make file so all the object files have an extension of .obj instead of .o. There's room for a lot of question whether that will fix everything though -- that may be all you need, or it may simply lead to other (probably more difficult) problems.

For Tomcat 8, I had to add the following line to tomcat/conf/logging.properties for the jars scanned by Tomcat to show up in the logs:

org.apache.jasper.servlet.TldScanner.level = FINE

I found that none of the answers here applied to my specific use case, so I thought I would share my solution.

I was looking to redirect an unauthentciated user to public version of an app page with any possible URL params. Example:

/app/4903294/my-great-car?email=coolguy%40gmail.com to

/public/4903294/my-great-car?email=coolguy%40gmail.com

Here's the solution that worked for me.

return redirect(url_for('app.vehicle', vid=vid, year_make_model=year_make_model, **request.args))

Hope this helps someone!

On your .m file, you can declare a variable as static:

static ClassName *variableName = nil;

Then you can initialize it on your +(void)initialize method.

Please note that this is a plain C static variable and is not static in the sense Java or C# consider it, but will yield similar results.

Here's a shortcut to DevTools:

2. F1 to open DevTools Settings
3. Check Disable cache (while DevTools is open) as shown below:

Look at shutil in the Python docs, specifically the copytree command.

If the destination directory already exists, try:

I know this thread is old but anyway I'm sharing, I have to install all third part dependencies of the imported assembly - as the imported assembly wasn't included as Nuget package thus its dependencies were missing.

Hop this help :)

If you want to get unix timestamp, then you need to use:

timestamp=$(date +%s)

%T will give you just the time; same as %H:%M:%S (via http://www.cyberciti.biz/faq/linux-unix-formatting-dates-for-display/)

Dim resources As Object = My.Resources.ResourceManager
PictureBoxName.Image = resources.GetObject("Company_Logo")

You can also use ViewPager.SimpleOnPageChangeListener instead of ViewPager.OnPageChangeListener and override only those methods you want to use.

viewPager.addOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {

    // optional 
    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { }

    // optional 
    @Override
    public void onPageSelected(int position) { }

    // optional 
    @Override
    public void onPageScrollStateChanged(int state) { }
});

Hope this help :)

Edit: As per android APIs, setOnPageChangeListener (ViewPager.OnPageChangeListener listener) is deprecated. Please check this url:- Android ViewPager API

Another approach is to use ls when reading the file list within a directory so as to give you what you want, i.e. "just the file name/s". As opposed to reading the full file path and then extracting the "file name" component in the body of the for loop.

Example below that follows your original:

for filename in $(ls /home/user/)
do
  echo $filename
done;

If you are running the script in the same directory as the files, then it simply becomes:

for filename in $(ls)
do
  echo $filename
done;

Right click your www folder and click on properties. Navigate to permissions and change all to read and write then click on "Apply permission to enclosed files" and your are done!! Maybe its too late but this will definitely help some other person

Actually you are right: it runs another instance of make. A possible solution would be:

.PHONY : clearscr fresh clean all

all :
    compile executable

clean :
    rm -f *.o $(EXEC)

fresh : clean clearscr all

clearscr:
    clear

By calling make fresh you get first the clean target, then the clearscreen which runs clear and finally all which does the job.

EDIT Aug 4

What happens in the case of parallel builds with make’s -j option? There's a way of fixing the order. From the make manual, section 4.2:

Occasionally, however, you have a situation where you want to impose a specific ordering on the rules to be invoked without forcing the target to be updated if one of those rules is executed. In that case, you want to define order-only prerequisites. Order-only prerequisites can be specified by placing a pipe symbol (|) in the prerequisites list: any prerequisites to the left of the pipe symbol are normal; any prerequisites to the right are order-only: targets : normal-prerequisites | order-only-prerequisites

The normal prerequisites section may of course be empty. Also, you may still declare multiple lines of prerequisites for the same target: they are appended appropriately. Note that if you declare the same file to be both a normal and an order-only prerequisite, the normal prerequisite takes precedence (since they are a strict superset of the behavior of an order-only prerequisite).

Hence the makefile becomes

.PHONY : clearscr fresh clean all

all :
    compile executable

clean :
    rm -f *.o $(EXEC)

fresh : | clean clearscr all

clearscr:
    clear

EDIT Dec 5

It is not a big deal to run more than one makefile instance since each command inside the task will be a sub-shell anyways. But you can have reusable methods using the call function.

log_success = (echo "\x1B[32m>> $1\x1B[39m")
log_error = (>&2 echo "\x1B[31m>> $1\x1B[39m" && exit 1)

install:
  @[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
  command1  # this line will be a subshell
  command2  # this line will be another subshell
  @command3  # Use `@` to hide the command line
  $(call log_error, "It works, yey!")

uninstall:
  @[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
  ....
  $(call log_error, "Nuked!")

2.0 Update (10/8/19) Setting TF_CPP_MIN_LOG_LEVEL should still work (see below in v0.12+ update), but there is currently an issue open (see issue #31870). If setting TF_CPP_MIN_LOG_LEVEL does not work for you (again, see below), try doing the following to set the log level:

import tensorflow as tf
tf.get_logger().setLevel('INFO')

In addition, please see the documentation on tf.autograph.set_verbosity which sets the verbosity of autograph log messages - for example:

# Can also be set using the AUTOGRAPH_VERBOSITY environment variable
tf.autograph.set_verbosity(1)

v0.12+ Update (5/20/17), Working through TF 2.0+:

In TensorFlow 0.12+, per this issue, you can now control logging via the environmental variable called TF_CPP_MIN_LOG_LEVEL; it defaults to 0 (all logs shown) but can be set to one of the following values under the Level column.

  Level | Level for Humans | Level Description                  
 -------|------------------|------------------------------------ 
  0     | DEBUG            | [Default] Print all messages       
  1     | INFO             | Filter out INFO messages           
  2     | WARNING          | Filter out INFO & WARNING messages 
  3     | ERROR            | Filter out all messages      

See the following generic OS example using Python:

import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3'  # or any {'0', '1', '2'}
import tensorflow as tf

You can set this environmental variable in the environment that you run your script in. For example, with bash this can be in the file ~/.bashrc, /etc/environment, /etc/profile, or in the actual shell as:

TF_CPP_MIN_LOG_LEVEL=2 python my_tf_script.py

To be thorough, you call also set the level for the Python tf_logging module, which is used in e.g. summary ops, tensorboard, various estimators, etc.

# append to lines above
tf.logging.set_verbosity(tf.logging.ERROR)  # or any {DEBUG, INFO, WARN, ERROR, FATAL}

For 1.14 you will receive warnings if you do not change to use the v1 API as follows:

# append to lines above
tf.compat.v1.logging.set_verbosity(tf.compat.v1.logging.ERROR)  # or any {DEBUG, INFO, WARN, ERROR, FATAL}

View the page below for information on TensorFlow logging; with the new update, you're able to set the logging verbosity to either DEBUG, INFO, WARN, ERROR, or FATAL. For example:

tf.logging.set_verbosity(tf.logging.ERROR)

The page additionally goes over monitors which can be used with TF-Learn models. Here is the page.

This doesn't block all logging, though (only TF-Learn). I have two solutions; one is a 'technically correct' solution (Linux) and the other involves rebuilding TensorFlow.

script -c 'python [FILENAME].py' | grep -v 'I tensorflow/'

For the other, please see this answer which involves modifying source and rebuilding TensorFlow.

Just put the html tags with there content and add the xmlns attribute with quotes after the equals and in between the quotes is http://www.w3.org/1999/xhtml

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

var d = "ha";
$(this).attr("href", "data:image/png;base64,abcdefghijklmnop").attr("download", "file-" + d + ".png");

Here's a working example with the name set as the current date: http://jsfiddle.net/Qjvb3/

1. Based on my experience, if you use "ipython.exe" in python-2.7.5/Scripts from other directory, as typing at the comamnd prompt as ipython notebook, *.ipynb files will be loaded and saved in the current directory. ("notebook" is just a comamnd line parameter) I think the "ipython notebook.exe" in Winpython top directory is not relevant for your request. As for me, I added the ipython.exe directory to the Path only.
2. If you want to make your profile in user directory, see below: https://code.google.com/p/winpython/wiki/Installation#Settings

Try following code in KeyPress event of textbox

if (char.IsLetter(e.KeyChar) == false  & 
        Convert.ToString(e.KeyChar) != Microsoft.VisualBasic.Constants.vbBack)
            e.Handled = true

I found a better library which transform the normal <select> <option> to bootsrap button dropdown format.

You may be able to adapt a version of the C++ virtual constructor idiom. As far as I know, C# doesn't support covariant return types. I believe that's on many peoples' wish lists.

If you want to read file from sd card. Then following code might be helpful for you.

 StringBuilder text = new StringBuilder();
    try {
    File sdcard = Environment.getExternalStorageDirectory();
    File file = new File(sdcard,"testFile.txt");

        BufferedReader br = new BufferedReader(new FileReader(file));  
        String line;   
        while ((line = br.readLine()) != null) {
                    text.append(line);
                    Log.i("Test", "text : "+text+" : end");
                    text.append('\n');
                    } }
    catch (IOException e) {
        e.printStackTrace();                    

    }
    finally{
            br.close();
    }       
    TextView tv = (TextView)findViewById(R.id.amount);  

    tv.setText(text.toString()); ////Set the text to text view.
  }

    }

If you wan to read file from asset folder then

AssetManager am = context.getAssets();
InputStream is = am.open("test.txt");

Or If you wan to read this file from res/raw foldery, where the file will be indexed and is accessible by an id in the R file:

InputStream is = getResources().openRawResource(R.raw.test);     

Good example of reading text file from res/raw folder

Currently as of Django 2.2, the recommended way when starting a new project is to create a custom user model that inherits from AbstractUser, then point AUTH_USER_MODEL to the model.

Source: https://docs.djangoproject.com/en/2.2/topics/auth/customizing/#using-a-custom-user-model-when-starting-a-project

Try this:

colnames(DF) = DF[1, ] # the first row will be the header
DF = DF[-1, ]          # removing the first row.

However, get a look if the data has been properly read. If you data.frame has numeric variables but the first row were characters, all the data has been read as character. To avoid this problem, it's better to save the data and read again with header=TRUE as you suggest. You can also get a look to this question: Reading a CSV file organized horizontally.

It's worth mentioning as another answer that if you're using eGit, and your classpath gets updated because of say, a test coverage tool like Clover, that sometimes there's a cleanup hiccup that does not completely delete the contents of /path/to/git/repository/<project name>/bin/

Essentially, I used Eclipse's Error Log View, identified what was causing issues during this cleanup effort, navigated to the source directory, and manually deleted the <project name>/bin directory. Once that finished I went back to Eclipse and refreshed (F5) my project and the error went away.

So, I was trying to enable the specific task of running RegAsm (register assembly) from a context menu. The issue I had was that the result would flash up and go away before I could read it. So I tried piping to Pause, which does not work when the command fails (as mentioned here Pause command not working in .bat script and here Batch file command PAUSE does not work). So I tried cmd /k but that leaves the window open for more commands (I just want to read the result). So I added a pause followed by exit to the chain, resulting in the following:

cmd /k C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm.exe "%1" /codebase \"%1\" & pause & exit

This works like a charm -- RegAsm runs on the file and shows its results, then a "Press any key to continue..." prompt is shown, then the command prompt window closes when a key is pressed.

P.S. For others who might be interested, you can use the following .reg file entries to add a dllfile association to .dll files and then a RegAsm command extension to that (notice the escaped quotes and backslashes):

[HKEY_CLASSES_ROOT\.dll]
"Content Type"="application/x-msdownload"
@="dllfile"

[HKEY_CLASSES_ROOT\dllfile]
@="Application Extension"

[HKEY_CLASSES_ROOT\dllfile\Shell\RegAsm]
@="Register Assembly"

[HKEY_CLASSES_ROOT\dllfile\Shell\RegAsm\command]
@="cmd /k C:\\Windows\\Microsoft.NET\\Framework\\v4.0.30319\\regasm.exe \"%1\" /codebase \"%1\" & pause & exit"

Now I have a nice right-click menu to register an assembly.

The exit() function is a type of function with a return type without an argument. It's defined by the stdlib header file.

You need to use ( exit(0) or exit(EXIT_SUCCESS)) or (exit(non-zero) or exit(EXIT_FAILURE) ).

If you want to pull a particular file from another branch just do

git checkout branch1 -- filenamefoo.txt

This will pull a version of the file from one branch into the current tree

Although I have seen the suggested methods used and working, I think that setting the value of an hidden field only using the JSON.stringify breaks the HTML...

Here I'll explain what I mean:

<input type="hidden" value="{"name":"John"}">

As you can see the first double quote after the open chain bracket could be interpreted by some browsers as:

<input type="hidden" value="{" rubbish >

So for a better approach to this I would suggest to use the encodeURIComponent function. Together with the JSON.stringify we shold have something like the following:

> encodeURIComponent(JSON.stringify({"name":"John"}))
> "%7B%22name%22%3A%22John%22%7D"

Now that value can be safely stored in an input hidden type like so:

<input type="hidden" value="%7B%22name%22%3A%22John%22%7D">

or (even better) using the data- attribute of the HTML element manipulated by the script that will consume the data, like so:

<div id="something" data-json="%7B%22name%22%3A%22John%22%7D"></div>

Now to read the data back we can do something like:

> var data = JSON.parse(decodeURIComponent(div.getAttribute("data-json")))
> console.log(data)
> Object {name: "John"}

You can add atom beauty package for formatting text in atom..

file --> setting --> Install

then you type atom-beautify in search area.

then click Package button.. select atom beuty and install it.

next you can format your text using (Alt + ctrl + b) or right click and select beautify editor contents

Fairly certain this cannot be done. However you could use your preferred server-side language to print the server's IP to the client, and then use it however you like. For example, in PHP:

<script type="text/javascript">
    var ip = "<?php echo $_SERVER['SERVER_ADDR']; ?>";
    alert(ip);
</script>

This depends on your server's security setup though - some may block this.

This worked for me on iOS 5.0 simulator.

1. Run the app on the simulator.

2. Go to the path where you can see something like this:

   /Users/arshad/Library/Application\ Support/iPhone\ Simulator/5.0/Applications/34BC3FDC-7398-42D4-9114-D5FEFC737512/…
   

3. Copy all the package contents including the app, lib, temp and Documents.

4. Clear all the applications installed on the simulator so that it is easier to see what is happening.

5. Run a pre-existing app you have on your simulator.

6. Look for the same package content for that application as in step 3 and delete all.

7. Paste the package contents that you have previously copied.

8. Close the simulator and start it again. The new app icon of the intended app will replace the old one.

Your nameContent variable is inside the function scope and not visible outside that function so if you want to use the nameContent outside of the function then declare it global inside the <script> tag and use inside functions without the var keyword as follows

<script language="javascript" type="text/javascript">
    var nameContent; // In the global scope
    function first(){
        nameContent=document.getElementById('full_name').value;
    }

    function second() {
        first();
        y=nameContent; 
        alert(y);
    }
    second();
</script>

For modern browsers, use td:nth-child(2) for the second td, and td:nth-child(3) for the third. Remember that these retrieve the second and third td for every row.

If you need compatibility with IE older than version 9, use sibling combinators or JavaScript as suggested by Tim. Also see my answer to this related question for an explanation and illustration of his method.

Try $(this).attr("src", urlAbsolute);

You can mount files or directories/folders it all depends on Source file or directory. And also you need to provide full path or if you are not sure you can use PWD. Here is a simple working example.

In this example, I am mounting env-commands file which already exists in my working directory

$ docker run  --rm -it -v ${PWD}/env-commands:/env-commands aravindgv/eosdt:1.0.5 /bin/bash -c "cat /env-commands"

Although this is an old question, I had the same question when using the Standard console version. The answer can be found in the Debian Live manual under the section 10.1 Customizing the live user. It says:

It is also possible to change the default username "user" and the default password "live".

I tried the username user and password live and it did work. If you want to run commands as root you can preface each command with sudo

Try this:

$('#select-meal-type').change(function(){
    var arr = $(this).val()
});

Demo

$('#select-meal-type').change(function(){_x000D_
  var arr = $(this).val();_x000D_
  console.log(arr)_x000D_
})

In my case i never put return inside a arrow function so my code is follow

`<ProductConsumer>
   {(myvariable)=>{
      return  <h1>{myvariable}</h1>
   }}
</ProductConsumer> `

There is a lot of answers, but I decided to add my own, because it's little different. It's based on OOP ;)

I created class DirectoryCleaner, which help me each time when I need to clean some directory.

public class DirectoryCleaner {
    private final File mFile;

    public DirectoryCleaner(File file) {
        mFile = file;
    }

    public void clean() {
        if (null == mFile || !mFile.exists() || !mFile.isDirectory()) return;
        for (File file : mFile.listFiles()) {
            delete(file);
        }
    }

    private void delete(File file) {
        if (file.isDirectory()) {
            for (File child : file.listFiles()) {
                delete(child);
            }
        }
        file.delete();

    }
}

It can be used to solve this problem in next way:

File dir = new File(Environment.getExternalStorageDirectory(), "your_directory_name");
new DirectoryCleaner(dir).clean();
dir.delete();

For properties for which css transition will affect, can use transitionend event, example for z-index:

$(".observed-element").on("webkitTransitionEnd transitionend", function(e) {_x000D_
  console.log("end", e);_x000D_
  alert("z-index changed");_x000D_
});_x000D_
_x000D_
$(".changeButton").on("click", function() {_x000D_
  console.log("click");_x000D_
  document.querySelector(".observed-element").style.zIndex = (Math.random() * 1000) | 0;_x000D_
});

.observed-element {_x000D_
  transition: z-index 1ms;_x000D_
  -webkit-transition: z-index 1ms;_x000D_
}_x000D_
div {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  border: 1px solid;_x000D_
  position: absolute;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<button class="changeButton">change z-index</button>_x000D_
<div class="observed-element"></div>

See wp_get_post_terms(), you'd do something like so:

global $post;
$terms = wp_get_post_terms( $post->ID, 'YOUR_TAXONOMY_NAME',array('fields' => 'ids') );

print_r($terms);

The solutions like cmd /c pause cause a new command interpreter to start and run in the background. Although acceptable in some cases, this isn't really ideal.

The solutions using Read-Host force the user to press Enter and are not really "any key".

This solution will give you a true "press any key to continue" interface and will not start a new interpreter, which will essentially mimic the original pause command.

Write-Host "Press any key to continue..."
[void][System.Console]::ReadKey($true)

"equals" is it. To be on the safe side, you should test for null-ness:

x == y || (x != null && x.equals(y))

the x==y tests for null==null, which IMHO should be true.

The code will be inlined by the JIT if it is called often enough, so performance considerations should not matter.

Of course, avoiding "Integer" in favor of plain "int" is the best way, if you can.

[Added]

Also, the null-check is needed to guarantee that the equality test is symmetric -- x.equals(y) should by the same as y.equals(x), but isn't if one of them is null.

Because both a and b have only one axis, as their shape is (3), and the axis parameter specifically refers to the axis of the elements to concatenate.

this example should clarify what concatenate is doing with axis. Take two vectors with two axis, with shape (2,3):

a = np.array([[1,5,9], [2,6,10]])
b = np.array([[3,7,11], [4,8,12]])

concatenates along the 1st axis (rows of the 1st, then rows of the 2nd):

np.concatenate((a,b), axis=0)
array([[ 1,  5,  9],
       [ 2,  6, 10],
       [ 3,  7, 11],
       [ 4,  8, 12]])

concatenates along the 2nd axis (columns of the 1st, then columns of the 2nd):

np.concatenate((a, b), axis=1)
array([[ 1,  5,  9,  3,  7, 11],
       [ 2,  6, 10,  4,  8, 12]])

to obtain the output you presented, you can use vstack

a = np.array([1,2,3])
b = np.array([4,5,6])
np.vstack((a, b))
array([[1, 2, 3],
       [4, 5, 6]])

You can still do it with concatenate, but you need to reshape them first:

np.concatenate((a.reshape(1,3), b.reshape(1,3)))
array([[1, 2, 3],
       [4, 5, 6]])

Finally, as proposed in the comments, one way to reshape them is to use newaxis:

np.concatenate((a[np.newaxis,:], b[np.newaxis,:]))

Make a call to the DB searching with myid (Id of the row) and get back specific columns:

var columns = db.Notifications
                .Where(x => x.Id == myid)
                .Select(n => new { n.NotificationTitle, 
                                   n.NotificationDescription, 
                                   n.NotificationOrder });

Generated Column is one of the good approach for MySql version which is 5.7.6 and above.

There are two kinds of Generated Columns:

• Virtual (default) - column will be calculated on the fly when a record is read from a table
• Stored - column will be calculated when a new record is written/updated in the table

Both types can have NOT NULL restrictions, but only a stored Generated Column can be a part of an index.

For current case, we are going to use stored generated column. To implement I have considered that both of the values required for calculation are present in table

CREATE TABLE order_details (price DOUBLE, quantity INT, amount DOUBLE AS (price * quantity));

INSERT INTO order_details (price, quantity) VALUES(100,1),(300,4),(60,8);

amount will automatically pop up in table and you can access it directly, also please note that whenever you will update any of the columns, amount will also get updated.

Zero and None both treated as same for if block, below code should work fine.

if number or number==0:
    return True

If your class path is fully specified in manifest, maybe you need the last version of java runtime environment. My problem fixed when i reinstalled the jre 8.

For .Net Core :-

public void ConfigureServices(IServiceCollection services)
{
    ...
    services.AddJsonFormatters(f => f.Converters.Add(new StringEnumConverter()));
    ...
}

The steps in order to make a full check are:

Prepare the captor :

ArgumentCaptor<SomeArgumentClass> someArgumentCaptor = ArgumentCaptor.forClass(SomeArgumentClass.class);

verify the call to dependent on component (collaborator of subject under test). times(1) is the default value, so ne need to add it.

verify(dependentOnComponent, times(1)).send(someArgumentCaptor.capture());

Get the argument passed to collaborator

SomeArgumentClass someArgument = messageCaptor.getValue();

someArgument can be used for assertions

I had the same problem in java and I solved it with a bit of logic and regex. I believe the same logic can be applied.First I read from the slq file into memory. Then I apply the following logic. It's pretty much what has been said before however I believe that using regex word bound is safer than expecting a new line char.

String pattern = "\\bGO\\b|\\bgo\\b";

String[] splitedSql = sql.split(pattern);
for (String chunk : splitedSql) {
  getJdbcTemplate().update(chunk);
}

This basically splits the sql string into an array of sql strings. The regex is basically to detect full 'go' words either lower case or upper case. Then you execute the different querys sequentially.

This should work

mysqldump --databases X --tables Y --where="1 limit 1000000"

You can override Text behaviour by adding this in any of your component using Text:

let oldRender = Text.prototype.render;
Text.prototype.render = function (...args) {
    let origin = oldRender.call(this, ...args);
    return React.cloneElement(origin, {
        style: [{color: 'red', fontFamily: 'Arial'}, origin.props.style]
    });
};

Edit: since React Native 0.56, Text.prototypeis not working anymore. You need to remove the .prototype :

let oldRender = Text.render;
Text.render = function (...args) {
    let origin = oldRender.call(this, ...args);
    return React.cloneElement(origin, {
        style: [{color: 'red', fontFamily: 'Arial'}, origin.props.style]
    });
};

I have make combination of answers above and made my solution.

So..

First in razor block create one string variable which will contain name value of controller and action that is called by user.

    @{
        string controllerAction =  ViewContext.RouteData.Values["Controller"].ToString() + ViewContext.RouteData.Values["Action"].ToString(); 
    }

Then use combination of HTML and Razor code:

    <ul class="nav navbar-nav">
        <li class="@(controllerAction == "HomeIndex" ? "active" : "" )">@Html.ActionLink("Home", "Index", "Home")</li>
        <li class="@(controllerAction == "AboutIndex" ? "active" : "" )">@Html.ActionLink("About", "Index", "About")</li>
        <li class="@(controllerAction == "HomeContact" ? "active" : "" )">@Html.ActionLink("Contact", "Contact", "Home")</li>
    </ul>

I think, that this is good because you don't need to access "ViewContext.RouteData.Values" each time to get controller name and action name.

You can directly go to Web IDE and upload your folder there.

Steps:

1. Go to Web IDE(Mostly located below the clone option).
2. Create new directory at your path
3. Upload your files and folders

In some cases you may not be able to directly upload entire folder containing folders, In such cases, you will have to create directory structure yourself.

I just looked and found cell|all output|clear which worked with:

Server Information: You are using Jupyter notebook.

The version of the notebook server is: 6.1.5 The server is running on this version of Python: Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:37:02) [MSC v.1924 64 bit (AMD64)]

Current Kernel Information: Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:37:02) [MSC v.1924 64 bit (AMD64)] Type 'copyright', 'credits' or 'license' for more information IPython 7.19.0 -- An enhanced Interactive Python. Type '?' for help.

Well, you can create your own type - but a DateTime always has a full date and time. You can't even have "just a date" using DateTime - the closest you can come is to have a DateTime at midnight.

You could always ignore the year though - or take the current year:

// Consider whether you want DateTime.UtcNow.Year instead
DateTime value = new DateTime(DateTime.Now.Year, month, day);

To create your own type, you could always just embed a DateTime within a struct, and proxy on calls like AddDays etc:

public struct MonthDay : IEquatable<MonthDay>
{
    private readonly DateTime dateTime;

    public MonthDay(int month, int day)
    {
        dateTime = new DateTime(2000, month, day);
    }

    public MonthDay AddDays(int days)
    {
        DateTime added = dateTime.AddDays(days);
        return new MonthDay(added.Month, added.Day);
    }

    // TODO: Implement interfaces, equality etc
}

Note that the year you choose affects the behaviour of the type - should Feb 29th be a valid month/day value or not? It depends on the year...

Personally I don't think I would create a type for this - instead I'd have a method to return "the next time the program should be run".

Depends on the situation, you can also try using padding property here...

MyControl.Margin=new Padding(0,0,0,0);

Python: You will need to add # - * - coding: UTF-8 - * - (remove the spaces around * ) to the first line of the python file. and then add the following to the text to encode: .encode('ascii', 'xmlcharrefreplace'). This will replace all the unicode characters with it's ASCII equivalent.

What type() means:

I think your question is a bit more general than I originally thought. type() with one argument returns the type or class of the object. So if you have a = 'abc' and use type(a) this returns str because the variable a is a string. If b = 10, type(b) returns int.

See also python documentation on type().

For comparisons:

If you want a comparison you could use: if type(v) == h5py.h5r.Reference (to check if it is a h5py.h5r.Reference instance).

But it is recommended that one uses if isinstance(v, h5py.h5r.Reference) but then also subclasses will evaluate to True.

If you want to print the class use print v.__class__.__name__.

More generally: You can compare if two instances have the same class by using type(v) is type(other_v) or isinstance(v, other_v.__class__).

This may sound obvious, but make sure the Controller where you are reading the headers in, is the first Controller where the request goes through.

I had two WebAPI projects communicating with each other. The first one was a proxy, the second contained the logic. Silly me, I tried reading the custom headers in the second Controller, instead of the first one.

What I can do to fix this (other than installing a real SSL certificate).

You can't.

On an https webpage you can only make AJAX request to https webpage (With a certificate trusted by the browser, if you use a self-signed one, it will not work for your visitors)

In my case, the .gitignore file is somehow corrupted. It sometimes shows up OK but sometimes is gibberish. I guess the encoding might be to blame but cannot be sure. To solve the issue, I deleted the file (previously created through echo > .gitgore in VS Code commandline) and created a new one manually in the file system (Explorer), then added my ignore rules. After the new .ignore was in place, everything works fine.

use DATE_DIFF

Select I.Fee
From   Item I
WHERE  DATEDIFF(day, GETDATE(), I.DateCreated)  < 365

Based on zapl's answer, adding try() around Closeable's closes the streams automatically after use.

public static void unzip(File zipFile, File targetDirectory) {
    try (FileInputStream fis = new FileInputStream(zipFile)) {
        try (BufferedInputStream bis = new BufferedInputStream(fis)) {
            try (ZipInputStream zis = new ZipInputStream(bis)) {
                ZipEntry ze;
                int count;
                byte[] buffer = new byte[Constant.DefaultBufferSize];

                            fout.write(buffer, 0, count);
                    }

Using Constant.DefaultBufferSize (65536) gotten from C# .NET 4 Stream.CopyTo from Jon Skeet's answer here: https://stackoverflow.com/a/411605/1876355

I always just see posts using byte[1024] or byte[4096] buffer, never knew it can be much larger which improves performance and is still working perfectly normal.

Here is the Stream Source code: https://referencesource.microsoft.com/#mscorlib/system/io/stream.cs

//We pick a value that is the largest multiple of 4096 that is still smaller than the large object heap threshold (85K).
// The CopyTo/CopyToAsync buffer is short-lived and is likely to be collected at Gen0, and it offers a significant
// improvement in Copy performance.

private const int _DefaultCopyBufferSize = 81920;

However, I dialed it back to 65536 which is also a multiple of 4096 just to be safe.

Delete has been recently added in Hive version 0.14 Deletes can only be performed on tables that support ACID Below is the link from Apache .

https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DML#LanguageManualDML-Delete

this will open the file with the default windows program (notepad if you haven't changed it);

Process.Start(@"c:\myfile.txt")

It's called a verbatim string literal in C#, and it's just a matter of putting @ before the literal. Not only does this allow multiple lines, but it also turns off escaping. So for example you can do:

string query = @"SELECT foo, bar
FROM table
WHERE name = 'a\b'";

This includes the line breaks (using whatever line break your source has them as) into the string, however. For SQL, that's not only harmless but probably improves the readability anywhere you see the string - but in other places it may not be required, in which case you'd either need to not use a multi-line verbatim string literal to start with, or remove them from the resulting string.

The only bit of escaping is that if you want a double quote, you have to add an extra double quote symbol:

string quote = @"Jon said, ""This will work,"" - and it did!";

For Power-Shell

./adb shell getprop | Select-String -Pattern '(model)|(version.sdk)|(manufacturer)|(platform)|(serialno)|(product.name)|(brand)'

For linux(burrowing asnwer from @0x8BADF00D)

adb shell getprop | grep "model\|version.sdk\|manufacturer\|hardware\|platform\|revision\|serialno\|product.name\|brand"

For single string find in power shell

./adb shell getprop | Select-String -Pattern 'model'

or

./adb shell getprop | Select-String -Pattern '(model)'

For multiple

./adb shell getprop | Select-String -Pattern '(a|b|c|d)'

This will probably have some performance costs when creating the connection but as connections are pooled, they are created only once and then reused, so it won't make any difference to your application. But as always: measure it.

UPDATE:

There are two authentication modes:

1. Windows Authentication mode (corresponding to a trusted connection). Clients need to be members of a domain.
2. SQL Server Authentication mode. Clients are sending username/password at each connection

So, I had this recently also, for integrated security, It turns out that my issue was actually fairly simple to fix but mainly because I had forgotten to add "Trusted_Connection=True" to my connection string.

I know that may seem fairly obvious but it had me going for 20 minutes or so until I realised that I had copied my connection string format from connectionstrings.com and that portion of the connection string was missing.

Simple and I feel a bit daft, but it was the answer for me.

To add some info that helped me today, a jQuery object/this can also be passed in to the .not() selector.

$(document).ready(function(){_x000D_
    $(".navitem").click(function(){_x000D_
        $(".navitem").removeClass("active");_x000D_
        $(".navitem").not($(this)).addClass("active");_x000D_
    });_x000D_
});

.navitem_x000D_
{_x000D_
    width: 100px;_x000D_
    background: red;_x000D_
    color: white;_x000D_
    display: inline-block;_x000D_
    position: relative;_x000D_
    text-align: center;_x000D_
}_x000D_
.navitem.active_x000D_
{_x000D_
    background:green;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<div class="navitem">Home</div>_x000D_
<div class="navitem">About</div>_x000D_
<div class="navitem">Pricing</div>

The above example can be simplified, but wanted to show the usage of this in the not() selector.

Click "view details" to find the inner exception.

You can do either…

$qb->where('e.fecha BETWEEN :monday AND :sunday')
   ->setParameter('monday', $monday->format('Y-m-d'))
   ->setParameter('sunday', $sunday->format('Y-m-d'));

or…

$qb->where('e.fecha > :monday')
   ->andWhere('e.fecha < :sunday')
   ->setParameter('monday', $monday->format('Y-m-d'))
   ->setParameter('sunday', $sunday->format('Y-m-d'));

I recommend Pygments. It accepts a piece of code in any language and outputs syntax highlighted LaTeX code. It uses fancyvrb and color packages to produce its output. I personally prefer it to the listing package. I think fancyvrb creates much prettier results.

I created a extention to response to this you could includ it in your projects, I think this return the most case when you search for duplicates in List or Linq.

Example:

//Dummy class to compare in list
public class Person
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Surname { get; set; }
    public Person(int id, string name, string surname)
    {
        this.Id = id;
        this.Name = name;
        this.Surname = surname;
    }
}


//The extention static class
public static class Extention
{
    public static IEnumerable<T> getMoreThanOnceRepeated<T>(this IEnumerable<T> extList, Func<T, object> groupProps) where T : class
    { //Return only the second and next reptition
        return extList
            .GroupBy(groupProps)
            .SelectMany(z => z.Skip(1)); //Skip the first occur and return all the others that repeats
    }
    public static IEnumerable<T> getAllRepeated<T>(this IEnumerable<T> extList, Func<T, object> groupProps) where T : class
    {
        //Get All the lines that has repeating
        return extList
            .GroupBy(groupProps)
            .Where(z => z.Count() > 1) //Filter only the distinct one
            .SelectMany(z => z);//All in where has to be retuned
    }
}

//how to use it:
void DuplicateExample()
{
    //Populate List
    List<Person> PersonsLst = new List<Person>(){
    new Person(1,"Ricardo","Figueiredo"), //fist Duplicate to the example
    new Person(2,"Ana","Figueiredo"),
    new Person(3,"Ricardo","Figueiredo"),//second Duplicate to the example
    new Person(4,"Margarida","Figueiredo"),
    new Person(5,"Ricardo","Figueiredo")//third Duplicate to the example
    };

    Console.WriteLine("All:");
    PersonsLst.ForEach(z => Console.WriteLine("{0} -> {1} {2}", z.Id, z.Name, z.Surname));
    /* OUTPUT:
        All:
        1 -> Ricardo Figueiredo
        2 -> Ana Figueiredo
        3 -> Ricardo Figueiredo
        4 -> Margarida Figueiredo
        5 -> Ricardo Figueiredo
        */

    Console.WriteLine("All lines with repeated data");
    PersonsLst.getAllRepeated(z => new { z.Name, z.Surname })
        .ToList()
        .ForEach(z => Console.WriteLine("{0} -> {1} {2}", z.Id, z.Name, z.Surname));
    /* OUTPUT:
        All lines with repeated data
        1 -> Ricardo Figueiredo
        3 -> Ricardo Figueiredo
        5 -> Ricardo Figueiredo
        */
    Console.WriteLine("Only Repeated more than once");
    PersonsLst.getMoreThanOnceRepeated(z => new { z.Name, z.Surname })
        .ToList()
        .ForEach(z => Console.WriteLine("{0} -> {1} {2}", z.Id, z.Name, z.Surname));
    /* OUTPUT:
        Only Repeated more than once
        3 -> Ricardo Figueiredo
        5 -> Ricardo Figueiredo
        */
}

You can use this:

<input type="checkbox" [checked]="record.status" (change)="changeStatus(record.id,$event)">

And on your ts file,

changeStatus(id, e) {
    var status = e.target.checked;
    this.yourseverice.changeStatus(id, status).subscribe(result => {
        if (status)
            this.notify.success(this.l('AddedAsKeyPeople'));
        else
            this.notify.success(this.l('RemovedFromKeyPeople'));

    });
}

Here, record is the model for current row and status is boolean value.

You can also create your plot using ggvis:

library(ggvis)

x  <- seq(-2, 2, 0.05)
y1 <- pnorm(x)
y2 <- pnorm(x,1,1)
df <- data.frame(x, y1, y2)

df %>%
  ggvis(~x, ~y1, stroke := 'red') %>%
  layer_paths() %>%
  layer_paths(data = df, x = ~x, y = ~y2, stroke := 'blue')

This will create the following plot:

In PHP and C++ you can use the printf() function

printf("$%01.2f", $money);

You cannot use ToString() on a null object so use a Null Coalescing Operator to assign an empty string to the null object then evaluate with IsNullOrEmpty

        var foo = obj ?? "";

        if (!String.IsNullOrEmpty(foo.ToString()))
        {
          //Do something
        }

You are facing a double-encoding issue.

¦ and • are absolutely equivalent to each other. Both refer to the Unicode character 'BULLET' (U+2022) and can exist side-by-side in HTML source code.

However, if that source-code is HTML-encoded again at some point, it will contain ¦ and •. The former is rendered unchanged, the latter will come out as "•" on the screen.

This is correct behavior under these circumstances. You need to find the point where the superfluous second HTML-encoding occurs and get rid of it.

Per the Android docs SystemClock.elapsedRealtime() is the recommend basis for general purpose interval timing. This is because, per the documentation, elapsedRealtime() is guaranteed to be monotonic, [...], so is the recommend basis for general purpose interval timing.

The SystemClock documentation has a nice overview of the various time methods and the applicable use cases for them.

• SystemClock.elapsedRealtime() and SystemClock.elapsedRealtimeNanos() are the best bet for calculating general purpose elapsed time.
• SystemClock.uptimeMillis() and System.nanoTime() are another possibility, but unlike the recommended methods, they don't include time in deep sleep. If this is your desired behavior then they are fine to use. Otherwise stick with elapsedRealtime().
• Stay away from System.currentTimeMillis() as this will return "wall" clock time. Which is unsuitable for calculating elapsed time as the wall clock time may jump forward or backwards. Many things like NTP clients can cause wall clock time to jump and skew. This will cause elapsed time calculations based on currentTimeMillis() to not always be accurate.

When the game starts:

long startTime = SystemClock.elapsedRealtime();

When the game ends:

long endTime = SystemClock.elapsedRealtime();
long elapsedMilliSeconds = endTime - startTime;
double elapsedSeconds = elapsedMilliSeconds / 1000.0;

Also, Timer() is a best effort timer and will not always be accurate. So there will be an accumulation of timing errors over the duration of the game. To more accurately display interim time, use periodic checks to System.currentTimeMillis() as the basis of the time sent to setText(...).

Also, instead of using Timer, you might want to look into using TimerTask, this class is designed for what you want to do. The only problem is that it counts down instead of up, but that can be solved with simple subtraction.

import urllib

def fetch_thing(url, params, method):
    params = urllib.urlencode(params)
    if method=='POST':
        f = urllib.urlopen(url, params)
    else:
        f = urllib.urlopen(url+'?'+params)
    return (f.read(), f.code)


content, response_code = fetch_thing(
                              'http://google.com/', 
                              {'spam': 1, 'eggs': 2, 'bacon': 0}, 
                              'GET'
                         )

[Update]

Some of these answers are old. Today I would use the requests module like the answer by robaple.

You can do it via callback function.

$('a.button').click(function(){
    if (condition == 'true'){
        function1(someVariable, function() {
          function2(someOtherVariable);
        });
    }
    else {
        doThis(someVariable);
    }
});

function function1(param, callback) { ...do stuff callback(); }

BigDecimal offers a string constructor. You'll need to strip all commas from the number, via via an regex or String filteredString=inString.replaceAll(",","").

You then simply call BigDecimal myBigD=new BigDecimal(filteredString);

You can also create a NumberFormat and call setParseBigDecimal(true). Then parse( will give you a BigDecimal without worrying about manually formatting.

No need for a plugin to check if outside of view port.

var w = Math.max(document.documentElement.clientWidth, window.innerWidth || 0)
var h = Math.max(document.documentElement.clientHeight, window.innerHeight || 0)
var d = $(document).scrollTop();

$.each($("div"),function(){
    p = $(this).position();
    //vertical
    if (p.top > h + d || p.top > h - d){
        console.log($(this))
    }
    //horizontal
    if (p.left < 0 - $(this).width() || p.left > w){
        console.log($(this))
    }
});

Dumping object content as JSON can be achieved without using ngFor. Example:

Object

export class SomeComponent implements OnInit {
    public theObject: any = {
        simpleProp: 1,
        complexProp: {
            InnerProp1: "test1",
            InnerProp2: "test2"
        },
        arrayProp: [1, 2, 3, 4]
    };

Markup

<div [innerHTML]="theObject | json"></div>

Output (ran through a beautifier for better readability, otherwise it is output in a single row)

{
  "simpleProp": 1,
  "complexProp": {
    "InnerProp1": "test1",
    "InnerProp2": "test2"
  },
  "arrayProp": [
    1,
    2,
    3,
    4
  ]
}

I have also discovered a JSON formatter and viewer that displays larger JSON data more readable (similar to JSONView Chrome extension): https://www.npmjs.com/package/ngx-json-viewer

<ngx-json-viewer [json]="someObject" [expanded]="false"></ngx-json-viewer>

This is a rewrite of the great post by @Kay, which throws IOException and provides an early exit:

/**
 * Gets image dimensions for given file 
 * @param imgFile image file
 * @return dimensions of image
 * @throws IOException if the file is not a known image
 */
public static Dimension getImageDimension(File imgFile) throws IOException {
  int pos = imgFile.getName().lastIndexOf(".");
  if (pos == -1)
    throw new IOException("No extension for file: " + imgFile.getAbsolutePath());
  String suffix = imgFile.getName().substring(pos + 1);
  Iterator<ImageReader> iter = ImageIO.getImageReadersBySuffix(suffix);
  while(iter.hasNext()) {
    ImageReader reader = iter.next();
    try {
      ImageInputStream stream = new FileImageInputStream(imgFile);
      reader.setInput(stream);
      int width = reader.getWidth(reader.getMinIndex());
      int height = reader.getHeight(reader.getMinIndex());
      return new Dimension(width, height);
    } catch (IOException e) {
      log.warn("Error reading: " + imgFile.getAbsolutePath(), e);
    } finally {
      reader.dispose();
    }
  }

  throw new IOException("Not a known image file: " + imgFile.getAbsolutePath());
}

I guess my rep is not high enough for my input to be considered worthy as a reply.

I wrote a simple jQuery plugin that will do what you are looking for.

https://github.com/afklondon/jquery.inactivity

$(document).inactivity( {
    interval: 1000, // the timeout until the inactivity event fire [default: 3000]
    mouse: true, // listen for mouse inactivity [default: true]
    keyboard: false, // listen for keyboard inactivity [default: true]
    touch: false, // listen for touch inactivity [default: true]
    customEvents: "customEventName", // listen for custom events [default: ""]
    triggerAll: true, // if set to false only the first "activity" event will be fired [default: false]
});

The script will listen for mouse, keyboard, touch and other custom events inactivity (idle) and fire global "activity" and "inactivity" events.

Hope this helps :)

There are probably embedded tabs (CHAR(9)) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:

DECLARE @var NVARCHAR(255), @i INT;

SET @i = 1;

SELECT @var = AccountType FROM dbo.Account
  WHERE AccountNumber = 200
  AND AccountType LIKE '%Daily%';

CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));

WHILE @i <= LEN(@var)
BEGIN
  INSERT #x 
    SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));

  SET @i = @i + 1;
END

SELECT i,c,a FROM #x ORDER BY i;

You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.

try

CREATE TABLE [dbo].[Names]
(
    [Name] [nvarchar](64) NOT NULL,
    [CreateTS] [smalldatetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [smalldatetime] NOT NULL

)

PS I think a smalldatetime is good enough. You may decide differently.

Can you not do this at the "moment of impact" ?

In Sql Server, this is common:

Update dbo.MyTable 
Set 

ColA = @SomeValue , 
UpdateDS = CURRENT_TIMESTAMP
Where...........

Sql Server has a "timestamp" datatype.

But it may not be what you think.

Here is a reference:

http://msdn.microsoft.com/en-us/library/ms182776(v=sql.90).aspx

Here is a little RowVersion (synonym for timestamp) example:

CREATE TABLE [dbo].[Names]
(
    [Name] [nvarchar](64) NOT NULL,
    RowVers rowversion ,
    [CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [datetime] NOT NULL

)


INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Update dbo.Names Set Name = Name

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Maybe a complete working example:

DROP TABLE [dbo].[Names]
GO


CREATE TABLE [dbo].[Names]
(
    [Name] [nvarchar](64) NOT NULL,
    RowVers rowversion ,
    [CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [datetime] NOT NULL

)

GO

CREATE TRIGGER dbo.trgKeepUpdateDateInSync_ByeByeBye ON dbo.Names
AFTER INSERT, UPDATE
AS

BEGIN

Update dbo.Names Set UpdateTS = CURRENT_TIMESTAMP from dbo.Names myAlias , inserted triggerInsertedTable where 
triggerInsertedTable.Name = myAlias.Name

END


GO






INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Update dbo.Names Set Name = Name , UpdateTS = '03/03/2003' /* notice that even though I set it to 2003, the trigger takes over */

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Matching on the "Name" value is probably not wise.

Try this more mainstream example with a SurrogateKey

DROP TABLE [dbo].[Names]
GO


CREATE TABLE [dbo].[Names]
(
    SurrogateKey int not null Primary Key Identity (1001,1),
    [Name] [nvarchar](64) NOT NULL,
    RowVers rowversion ,
    [CreateTS] [datetime] NOT NULL CONSTRAINT CreateTS_DF DEFAULT CURRENT_TIMESTAMP,
    [UpdateTS] [datetime] NOT NULL

)

GO

CREATE TRIGGER dbo.trgKeepUpdateDateInSync_ByeByeBye ON dbo.Names
AFTER UPDATE
AS

BEGIN

   UPDATE dbo.Names
    SET UpdateTS = CURRENT_TIMESTAMP
    From  dbo.Names myAlias
    WHERE exists ( select null from inserted triggerInsertedTable where myAlias.SurrogateKey = triggerInsertedTable.SurrogateKey)

END


GO






INSERT INTO dbo.Names (Name,UpdateTS)
select 'John' , CURRENT_TIMESTAMP
UNION ALL select 'Mary' , CURRENT_TIMESTAMP
UNION ALL select 'Paul' , CURRENT_TIMESTAMP

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

Update dbo.Names Set Name = Name , UpdateTS = '03/03/2003' /* notice that even though I set it to 2003, the trigger takes over */

select *  ,  ConvertedRowVers = CONVERT(bigint,RowVers) from [dbo].[Names]

top level class: internal
method: private
members (unless an interface or enum): private (including nested classes)
members (of interface or enum): public
constructor: private (note that if no constructor is explicitly defined, a public default constructor will be automatically defined)
delegate: internal
interface: internal
explicitly implemented interface member: public!

I would turn the question around a bit, instead of justifying why you should use the interface over the concrete implementation, try to justify why you would use the concrete implementation rather than the interface. If you can't justify it, use the interface.

Rather than locks, I suggest you look at long-running transactions, using v$transaction. From there you can join to v$session, which should give you an idea about the UI (try the program and machine columns) as well as the user.

Or simply

add to your element

[ngStyle]="{'color': myVariableColor}"

eg

<mat-icon [ngStyle]="{'color': myVariableColor}">{{ getActivityIcon() }}</mat-icon>

Where color can be defined at another component etc

Converting Binary into hex without ignoring leading zeros:

You could use the format() built-in function like this:

"{0:0>4X}".format(int("0000010010001101", 2))

For anaconda installation, first pick a channel which has the latest version of tensorflow binary. Usually, the latest versions are available at the channel conda-forge. Then simply do:

conda update -f -c conda-forge tensorflow

This will upgrade your existing tensorflow installation to the very latest version available. As of this writing, the latest version is 1.4.0-py36_0

Try this:

<tr ng-repeat="player in players | filter:{id: player_id, name:player_name} | filter:ageFilter">

$scope.ageFilter = function (player) {
    return (player.age > $scope.min_age && player.age < $scope.max_age);
}

I needed the class name in the static methods of multiple classes so I implemented a JavaUtil Class with the following method :

public static String getClassName() {
    String className = Thread.currentThread().getStackTrace()[2].getClassName();
    int lastIndex = className.lastIndexOf('.');
    return className.substring(lastIndex + 1);
}

Hope it will help !

Try a clear: left on #inner2. Because they are both being set to float it should cause a line return.

#inner1 {_x000D_
   float:left; _x000D_
}_x000D_
_x000D_
#inner2{_x000D_
   float:left; _x000D_
   clear: left;_x000D_
}

<div id="wrapper">_x000D_
    <div id="inner1">This is inner div 1</div>_x000D_
    <div id="inner2">This is inner div 2</div>_x000D_

I am using Guava which has annotation included:

(Gradle code )

compile 'com.google.guava:guava:23.4-jre'

You can do it by making the background into a pattern:

<defs>
  <pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
    <image href="wall.jpg" x="0" y="0" width="100" height="100" />
  </pattern>
</defs>

Adjust the width and height according to your image, then reference it from the path like this:

<path d="M5,50
         l0,100 l100,0 l0,-100 l-100,0
         M215,100
         a50,50 0 1 1 -100,0 50,50 0 1 1 100,0
         M265,50
         l50,100 l-100,0 l50,-100
         z"
  fill="url(#img1)" />

Working example

console.log() in java is System.out.println(); to put text on the next line

And System.out.print(); puts text on the same line.

By default, oracle date subtraction returns a result in # of days.

So just multiply by 24 to get # of hours, and again by 60 for # of minutes.

Example:

select
  round((second_date - first_date) * (60 * 24),2) as time_in_minutes
from
  (
  select
    to_date('01/01/2008 01:30:00 PM','mm/dd/yyyy hh:mi:ss am') as first_date
   ,to_date('01/06/2008 01:35:00 PM','mm/dd/yyyy HH:MI:SS AM') as second_date

Use the map function (in Python 2.x):

results = map(int, results)

In Python 3, you will need to convert the result from map to a list:

results = list(map(int, results))

When interviewing recently, I was often asked to implement a data structure, usually LinkedList or HashMap. Both of these are easy enough to be doable in a short time, and difficult enough to eliminate the clueless.

I had the same problem, and in my case, the solution was updating the usb-serial driver using windows update on windows 10 device's manager. There was no need to download a especific driver, I just let windows update find a suitable driver.

Furthermore, you also have || which is the logical or, and also ; which is just a separator which doesn't care what happend to the command before.

$ false || echo "Oops, fail"
Oops, fail

$ true || echo "Will not be printed"
$  

$ true && echo "Things went well"
Things went well

$ false && echo "Will not be printed"
$

$ false ; echo "This will always run"
This will always run

Some details about this can be found here Lists of Commands in the Bash Manual.

You're comparing strings. JavaScript compares the ASCII code for each character of the string.

To see why you get false, look at the charCodes:

"1300".charCodeAt(0);
49
"999".charCodeAt(0);
57

The comparison is false because, when comparing the strings, the character codes for 1 is not greater than that of 9.

The fix is to treat the strings as numbers. You can use a number of methods:

parseInt(string, radix)
parseInt("1300", 10);
> 1300 - notice the lack of quotes


+"1300"
> 1300


Number("1300")
> 1300

As of 2017, it's just brew install r. See @Andrew's answer below.

As of 2014 (using an Yosemite), the method is the following:

brew tap homebrew/science
brew install Caskroom/cask/xquartz
brew install r

The gcc package (will be installed automatically as a required dependency) in the homebrew/science tap already contains the latest fortran compiler (gfortran), and most of all: the whole package is precompiled so it saves you a lot of compilation time.

This answer will also work for El Capitan and Mac OS Sierra.

In case you don't have XCode Command Line Tools (CLT), run from terminal:

xcode-select --install

Just Override the boolean equals() method of custom object. Say you have an ArrayList with custom field f1, f2, ... override

@Override
public boolean equals(Object o) {
    if (this == o) return true;
    if (!(o instanceof CustomObject)) return false;

    CustomObject object = (CustomObject) o;

    if (!f1.equals(object.dob)) return false;
    if (!f2.equals(object.fullName)) return false;
    ...
    return true;
}

and check using ArrayList instance's contains() method. That's it.

Presumably, those columns are integer columns - which will be the reason as the result of the calculation will be of the same type.

e.g. if you do this:

SELECT 1 / 2

you will get 0, which is obviously not the real answer. So, convert the values to e.g. decimal and do the calculation based on that datatype instead.

e.g.

SELECT CAST(1 AS DECIMAL) / 2

gives 0.500000

You can also use

./gradlew clean build (Mac and Linux) -With ./

gradlew clean build (Windows) -Without ./

it removes build folder, as well configure your modules and then build your project.

i use it before release any new app on playstore.

To add to MattDMo's answer, you can get the exact font that's used on Linux like so (the example is from Xubuntu 14.04):

$ fc-match Monospace
DejaVuSansMono.ttf: "DejaVu Sans Mono" "Book"

I normally just run git mergetool and it will prompt me if I want to keep the modified file or keep it deleted. This is the quickest way IMHO since it's one command instead of several per file.

If you have a bunch of deleted files in a specific subdirectory and you want all of them to be resolved by deleting the files, you can do this:

yes d | git mergetool -- the/subdirectory

The d is provided to choose deleting each file. You can also use m to keep the modified file. Taken from the prompt you see when you run mergetool:

Use (m)odified or (d)eleted file, or (a)bort?

<servlet-mapping>
  <servlet-name>dispatcher</servlet-name>
  <url-pattern>/*</url-pattern>
</servlet-mapping>

change to:

<servlet-mapping>
  <servlet-name>dispatcher</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

The command

x/i $pc

can be set to run all the time using the usual configuration mechanism.

If you have a Microsoft Virtual WiFi Miniport Adapter as one of the available network adapters, you may do the following:

• Run Windows Command Processor (cmd) as Administrator
• Type: netsh wlan set hostednetwork mode=allow ssid=NAME key=PASSWORD
• Then: netsh wlan start hostednetwork
• Open "Control Panel\Network and Internet\Network Connections"
• Right-click on your active network adapter (the one that you use to connect on the internet) and then click Properties
• Then open Sharing tab
• Check "Allow other network users to connect..." and select your WiFi Miniport Adapter
• Once finished, type: netsh wlan stop hostednetwork

That's it!

use coalesce

COALESCE(value [, ...])

The COALESCE function returns the first of its arguments that is not null.  
Null is returned only if all arguments are null. It is often
used to substitute a default value for null values when data is
retrieved for display.

Edit

Here's an example of COALESCE with your query:

SELECT AVG( price )
FROM(
      SELECT *, cume_dist() OVER ( ORDER BY price DESC ) FROM web_price_scan
      WHERE listing_Type = 'AARM'
        AND u_kbalikepartnumbers_id = 1000307
        AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
        AND COALESCE( price, 0 ) > ( SELECT AVG( COALESCE( price, 0 ) )* 0.50
                                     FROM ( SELECT *, cume_dist() OVER ( ORDER BY price DESC )
                                           FROM web_price_scan
                                           WHERE listing_Type='AARM'
                                             AND u_kbalikepartnumbers_id = 1000307
                                             AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
                                         ) g
                                    WHERE cume_dist < 0.50
                                  )
        AND COALESCE( price, 0 ) < ( SELECT AVG( COALESCE( price, 0 ) ) *2
                                     FROM( SELECT *, cume_dist() OVER ( ORDER BY price desc )
                                           FROM web_price_scan
                                           WHERE listing_Type='AARM'
                                             AND u_kbalikepartnumbers_id = 1000307
                                             AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
                                         ) d
                                     WHERE cume_dist < 0.50)
     )s
HAVING COUNT(*) > 5

IMHO COALESCE should not be use with AVG because it modifies the value. NULL means unknown and nothing else. It's not like using it in SUM. In this example, if we replace AVG by SUM, the result is not distorted. Adding 0 to a sum doesn't hurt anyone but calculating an average with 0 for the unknown values, you don't get the real average.

In that case, I would add price IS NOT NULL in WHERE clause to avoid these unknown values.

Yes, the original question was asked eight years ago, but it's actually relevant today as its always been. Now, I've been going from pillar to post over this issue of ::before, for about a week ::after, and its been driving me round the bend.

From this page, and others on the subject - I've finally put it together and sized an image down in the pseudo tag.

** Running note .colnav is just my container class, that holds an < UL > and < LI > set of tags with a set of < a hrefs inside.

Below is the code (complete)

.colnav li.nexus-button a:hover:before {   
    background-image: url('/images/fleur-de-lis.png');
    background-size: 90px 20px;
    background-repeat: no-repeat;
    width: 130px;
    height: 20px;
    margin-left: -120px;
    margin-top: -3px;
    transform: scale(1.5);
    content: "";
    position: absolute;
}

The image file was (is) 120 x 80, and the picture got reduced right down to 90x 20, where it then fitted quite nicely behind the html href tag, and it all came together with that position: absolute statement at the end.

Change string[] lines = File.ReadLines("c:\\file.txt"); to IEnumerable<string> lines = File.ReadLines("c:\\file.txt"); The rest of your code should work fine.

For those who are still having hard time understanding this strtok() function, take a look at this pythontutor example, it is a great tool to visualize your C (or C++, Python ...) code.

In case the link got broken, paste in:

#include <stdio.h>
#include <string.h>

int main()
{
    char s[] = "Hello, my name is? Matthew! Hey.";
    char* p;
    for (char *p = strtok(s," ,?!."); p != NULL; p = strtok(NULL, " ,?!.")) {
      puts(p);
    }
    return 0;
}

use the scan method e.g.

 curl -XGET 'localhost:9200/_search?search_type=scan&scroll=10m&size=50' -d '
 {
    "query" : {
       "match_all" : {}
     }

edit included the newer across() syntax

Here's another tidyverse solution, using filter(across()) or previously filter_at. The advantage is that you can easily extend to more than one column.

Below also a solution with filter_all in order to find the string in any column, using diamonds as example, looking for the string "V"

library(tidyverse)

String in only one column

# for only one column... extendable to more than one creating a column list in `across` or `vars`!
mtcars %>% 
  rownames_to_column("type") %>% 
  filter(across(type, ~ !grepl('Toyota|Mazda', .))) %>%
  head()
#>                type  mpg cyl  disp  hp drat    wt  qsec vs am gear carb
#> 1        Datsun 710 22.8   4 108.0  93 3.85 2.320 18.61  1  1    4    1
#> 2    Hornet 4 Drive 21.4   6 258.0 110 3.08 3.215 19.44  1  0    3    1
#> 3 Hornet Sportabout 18.7   8 360.0 175 3.15 3.440 17.02  0  0    3    2
#> 4           Valiant 18.1   6 225.0 105 2.76 3.460 20.22  1  0    3    1
#> 5        Duster 360 14.3   8 360.0 245 3.21 3.570 15.84  0  0    3    4
#> 6         Merc 240D 24.4   4 146.7  62 3.69 3.190 20.00  1  0    4    2

The now superseded syntax for the same would be:

mtcars %>% 
  rownames_to_column("type") %>% 
  filter_at(.vars= vars(type), all_vars(!grepl('Toyota|Mazda',.))) 

String in all columns:

# remove all rows where any column contains 'V'
diamonds %>%
  filter(across(everything(), ~ !grepl('V', .))) %>%
  head
#> # A tibble: 6 x 10
#>   carat cut     color clarity depth table price     x     y     z
#>   <dbl> <ord>   <ord> <ord>   <dbl> <dbl> <int> <dbl> <dbl> <dbl>

#> 6  0.31 Ideal   J     SI2      62.2    54   344  4.35  4.37  2.71

The now superseded syntax for the same would be:

diamonds %>% 
  filter_all(all_vars(!grepl('V', .))) %>%
  head

I tried to find an across alternative for the following, but I didn't immediately come up with a good solution:

    #get all rows where any column contains 'V'
    diamonds %>%
    filter_all(any_vars(grepl('V',.))) %>%
      head
    #> # A tibble: 6 x 10
    #>   carat cut       color clarity depth table price     x     y     z
    #>   <dbl> <ord>     <ord> <ord>   <dbl> <dbl> <int> <dbl> <dbl> <dbl>

Update: Thanks to user Petr Kajzar in this answer, here also an approach for the above:

diamonds %>%
   filter(rowSums(across(everything(), ~grepl("V", .x))) > 0)

TRY THIS:

StringVariable=ByteVariable.decode('UTF-8','ignore')

TO TEST TYPE:

print(type(StringVariable))

Here 'StringVariable' represented as a string. 'ByteVariable' represent as Byte. Its not relevent to question Variables..

You can use the IPython.display.clear_output to clear the output as mentioned in cel's answer. I would add that for me the best solution was to use this combination of parameters to print without any "shakiness" of the notebook:

from IPython.display import clear_output

for i in range(10):
    clear_output(wait=True)
    print(i, flush=True)

This should work

if(!Directory.Exists(@"C:\MP_Upload")) {
    Directory.CreateDirectory(@"C:\MP_Upload");
}

This solution will work regardless of the number of char variables you have:

char c1 = 'z';
char c2 = 'w';
std::string s1{c1};
std::string s12{c1, c2};

Don't fart around with inserting spaces. For one, older versions of IE won't know what you're talking about. Besides that, though, there are cleaner ways in general.

For colorless indents, use the text-indent property.

p { text-indent: 1em; }

JSFiddle demo

Edit:

If you want the space to be colored, you might consider adding a thick left border to the first letter. (I'd almost-but-not-quite say "instead", because the indent can be an issue if you use both. But it feels dirty to me to rely solely on the border to indent.) You can specify how far away, and how wide, the color is using the first letter's left margin/padding/border width.

p:first-letter { border-left: 1em solid red; }

Demo

If you use Heroku or otherwise have need to keep your application settings as environment variables, the figaro gem is very helpful.

You do not need it.

If your action has the HttpPost attribute, then you do not need to bother with setting the JsonRequestBehavior and use the overload without it. There is an overload for each method without the JsonRequestBehavior enum. Here they are:

Without JsonRequestBehavior

protected internal JsonResult Json(object data);
protected internal JsonResult Json(object data, string contentType);
protected internal virtual JsonResult Json(object data, string contentType, Encoding contentEncoding);

With JsonRequestBehavior

protected internal JsonResult Json(object data, JsonRequestBehavior behavior);
protected internal JsonResult Json(object data, string contentType, 
                                   JsonRequestBehavior behavior);
protected internal virtual JsonResult Json(object data, string contentType, 
    Encoding contentEncoding, JsonRequestBehavior behavior);

    listView.setOnLongClickListener(new View.OnLongClickListener() {
    @Override
    public boolean onLongClick(View view) {
        return false;
    }
});

Definitely does the trick.

This is caused by the STRICT_TRANS_TABLES SQL mode defined in the

%PROGRAMDATA%\MySQL\MySQL Server 5.6\my.ini

file. Removing that setting and restarting MySQL should fix the problem.

See https://www.farbeyondcode.com/Solution-for-MariaDB-Field--xxx--doesn-t-have-a-default-value-5-2720.html

If editing that file doesn't fix the issue, see http://dev.mysql.com/doc/refman/5.6/en/option-files.html for other possible locations of config files.

Neither <iostream> nor <iostream.h> are standard C header files. Your code is meant to be C++, where <iostream> is a valid header. Use g++ (and a .cpp file extension) for C++ code.

Alternatively, this program uses mostly constructs that are available in C anyway. It's easy enough to convert the entire program to compile using a C compiler. Simply remove #include <iostream> and using namespace std;, and replace cout << endl; with putchar('\n');... I advise compiling using C99 (eg. gcc -std=c99)

For immutable data types:

l = [0] * 100
# [0, 0, 0, 0, 0, ...]

l = ['foo'] * 100
# ['foo', 'foo', 'foo', 'foo', ...]

For values that are stored by reference and you may wish to modify later (like sub-lists, or dicts):

l = [{} for x in range(100)]

(The reason why the first method is only a good idea for constant values, like ints or strings, is because only a shallow copy is does when using the <list>*<number> syntax, and thus if you did something like [{}]*100, you'd end up with 100 references to the same dictionary - so changing one of them would change them all. Since ints and strings are immutable, this isn't a problem for them.)

If you want to add to an existing list, you can use the extend() method of that list (in conjunction with the generation of a list of things to add via the above techniques):

a = [1,2,3]
b = [4,5,6]
a.extend(b)
# a is now [1,2,3,4,5,6]

For substracting in moment.js:

moment().subtract(1, 'months').format('MMM YYYY');

Documentation:

http://momentjs.com/docs/#/manipulating/subtract/

Before version 2.8.0, the moment#subtract(String, Number) syntax was also supported. It has been deprecated in favor of moment#subtract(Number, String).

  moment().subtract('seconds', 1); // Deprecated in 2.8.0
  moment().subtract(1, 'seconds');

As of 2.12.0 when decimal values are passed for days and months, they are rounded to the nearest integer. Weeks, quarters, and years are converted to days or months, and then rounded to the nearest integer.

  moment().subtract(1.5, 'months') == moment().subtract(2, 'months')
  moment().subtract(.7, 'years') == moment().subtract(8, 'months') //.7*12 = 8.4, rounded to 8

Requesting Permissions In the following code, we will ask for camera permission:

in java

EasyPermissions is a wrapper library to simplify basic system permissions logic when targeting Android M or higher.

Installation EasyPermissions is installed by adding the following dependency to your build.gradle file:

dependencies {

    // For developers using AndroidX in their applications
    implementation 'pub.devrel:easypermissions:3.0.0'

    // For developers using the Android Support Library
    implementation 'pub.devrel:easypermissions:2.0.1'

}


private void askAboutCamera(){

        EasyPermissions.requestPermissions(
                this,
                "A partir deste ponto a permissão de câmera é necessária.",
                CAMERA_REQUEST_CODE,
                Manifest.permission.CAMERA );
}

I found that I can run this command:

notepad $((Split-Path $profile -Parent) + "\profile.ps1")

and it opens my default powershell profile (at least when using Terminal for Windows). I found that here.

Then add an alias. For example, here is my alias of jn for jupyter notebook (I hate typing out the cumbersome jupyter notebook every time):

Set-Alias -Name jn -Value C:\Users\words\Anaconda3\Scripts\jupyter-notebook.exe

You can also use .split("[|]").

(I used this instead of .split("\\|"), which didn't work for me.)

You can pass a mutable container datatype into a function, and it can contain anything you want.

If you need a different functionality, name the functions differently, or if you need the same interface, just write an interface function (or method) that calls the functions appropriately based on the data received.

It took a while to me to get adjusted to this coming from Java, but it really isn't a "big handicap".

Using Linq we can simplify this by this

 Enumerable.Range(0, (int)(to - from).TotalHours + 1)
            .Select(i => from.AddHours(i)).Where(date => date.TimeOfDay >= new TimeSpan(8, 0, 0) && date.TimeOfDay <= new TimeSpan(18, 0, 0))

Even if you do not have the pid, you can trigger 'wait;' after triggering all background processes. For. eg. in commandfile.sh-

bteq < input_file1.sql > output_file1.sql &
bteq < input_file2.sql > output_file2.sql &
bteq < input_file3.sql > output_file3.sql &
wait

Then when this is triggered, as -

subprocess.call(['sh', 'commandfile.sh'])
print('all background processes done.')

This will be printed only after all the background processes are done.

This stuff comes from ES file explorer

Just go into this app > settings

Then there is an option that says logging floating window, you just need to disable that and you will get rid of this infernal bubble for good

thatLine = thatLine.replace('\n', '<br />')

Strings in Python are immutable. You might need to recreate it with the assignment operator.

You can use Mode.mode1.name() however you often don't need to do this.

Mode mode =
System.out.println("The mode is "+mode);

In Python you can use (.)\1{9,}

• (.) makes group from one char (any char)
• \1{9,} matches nine or more characters from 1st group

example:

txt = """1. aaaaaaaaaaaaaaa
2. bb
3. cccccccccccccccccccc
4. dd
5. eeeeeeeeeeee"""
rx = re.compile(r'(.)\1{9,}')
lines = txt.split('\n')
for line in lines:
    rxx = rx.search(line)
    if rxx:
        print line

Output:

1. aaaaaaaaaaaaaaa
3. cccccccccccccccccccc
5. eeeeeeeeeeee

Use a div #overlay with your loading info / .gif that will cover all your page:

<div id="overlay">
     <img src="loading.gif" alt="Loading" />
     Loading...
</div>

jQuery:

$(window).load(function(){
   // PAGE IS FULLY LOADED  
   // FADE OUT YOUR OVERLAYING DIV
   $('#overlay').fadeOut();
});

Here's an example with a Loading bar:

jsBin demo

  <div id="overlay">
    <div id="progstat"></div>
    <div id="progress"></div>
  </div>

  <div id="container">
    <img src="http://placehold.it/3000x3000/cf5">
  </div>

CSS:

*{margin:0;}
body{ font: 200 16px/1 sans-serif; }
img{ width:32.2%; }

#overlay{
  position:fixed;
  z-index:99999;
  top:0;
  left:0;
  bottom:0;
  right:0;
  background:rgba(0,0,0,0.9);
  transition: 1s 0.4s;
}
#progress{
  height:1px;
  background:#fff;
  position:absolute;
  width:0;                /* will be increased by JS */
  top:50%;
}
#progstat{
  font-size:0.7em;
  letter-spacing: 3px;
  position:absolute;
  top:50%;
  margin-top:-40px;
  width:100%;
  text-align:center;
  color:#fff;
}

JavaScript:

;(function(){
  function id(v){ return document.getElementById(v); }
  function loadbar() {
    var ovrl = id("overlay"),
        prog = id("progress"),
        stat = id("progstat"),
        img = document.images,
        c = 0,
        tot = img.length;
    if(tot == 0) return doneLoading();

    function imgLoaded(){
      c += 1;
      var perc = ((100/tot*c) << 0) +"%";
      prog.style.width = perc;
      stat.innerHTML = "Loading "+ perc;
      if(c===tot) return doneLoading();
    }
    function doneLoading(){
      ovrl.style.opacity = 0;
      setTimeout(function(){ 
        ovrl.style.display = "none";
      }, 1200);
    }
    for(var i=0; i<tot; i++) {
      var tImg     = new Image();
      tImg.onload  = imgLoaded;
      tImg.onerror = imgLoaded;
      tImg.src     = img[i].src;
    }    
  }
  document.addEventListener('DOMContentLoaded', loadbar, false);
}());

Setters/getters in Swift are quite different than ObjC. The property becomes a computed property which means it does not have a backing variable such as _x as it would in ObjC.

In the solution code below you can see the xTimesTwo does not store anything, but simply computes the result from x.

See Official docs on computed properties.

The functionality you want might also be Property Observers.

What you need is:

var x: Int

var xTimesTwo: Int {
    set {
       x = newValue / 2
    }
    get {
        return x * 2
    }
}

You can modify other properties within the setter/getters, which is what they are meant for.

You can use the jQuery plugin PositionCalculator

That plugin has also included collision handling (flip), so the toolbar-like menu can be placed at a visible position.

$(".placeholder").on('mouseover', function() {
    var $menu = $("#menu").show();// result for hidden element would be incorrect
    var pos = $.PositionCalculator( {
        target: this,
        targetAt: "top right",
        item: $menu,
        itemAt: "top left",
        flip: "both"
    }).calculate();

    $menu.css({
        top: parseInt($menu.css('top')) + pos.moveBy.y + "px",
        left: parseInt($menu.css('left')) + pos.moveBy.x + "px"
    });
});

for that markup:

<ul class="popup" id="menu">
    <li>Menu item</li>
    <li>Menu item</li>
    <li>Menu item</li>
</ul>

<div class="placeholder">placeholder 1</div>
<div class="placeholder">placeholder 2</div>

Here is the fiddle: http://jsfiddle.net/QrrpB/1657/

The range() function in python is a way to generate a sequence. Sequences are objects that can be indexed, like lists, strings, and tuples. An easy way to check for a sequence is to try retrieve indexed elements from them. It can also be checked using the Sequence Abstract Base Class(ABC) from the collections module.

from collections import Sequence as sq
isinstance(foo, sq)

The range() takes three arguments start, stop and step.

1. start : The staring element of the required sequence
2. stop : (n+1)th element of the required sequence
3. step : The required gap between the elements of the sequence. It is an optional parameter that defaults to 1.

To get your desired result you can make use of the below syntax.

range(1,c+1,2)

Now ES6 have arrow function it really helpful if you really confuse with bind(this) expression you can try arrow function

This is how I do.

componentWillMount() {
        ListApi.getList()
            .then(JsonList => this.setState({ List: JsonList }));
    }

 //Above method equalent to this...
     componentWillMount() {
         ListApi.getList()
             .then(function (JsonList) {
                 this.setState({ List: JsonList });
             }.bind(this));
 }

Yes, it is fine to use both:

'''
Comments
'''

and

"""
Comments
"""

But, the only thing you all need to remember while running in an IDE, is you have to 'RUN' the entire file to be accepted as multiple lines codes. Line by line 'RUN' won't work properly and will show an error.

In my case, the site was fine in server but not in local. Then I remember I was working on secure website.
So in file config.session.php, set the variable secure to false

'secure' => env('SESSION_SECURE_COOKIE', false),

The answer @Ro Hit gave helped me a lot, but I was missing the user credentials because I had to fake a user for authentication unit testing. Hence, let me describe how I solved it.

According to this, if you add the method

    // using System.Security.Principal;
    GenericPrincipal FakeUser(string userName)
    {
        var fakeIdentity = new GenericIdentity(userName);
        var principal = new GenericPrincipal(fakeIdentity, null);
        return principal;
    }

and then append

    HttpContext.Current.User = FakeUser("myDomain\\myUser");

to the last line of the TestSetup method you're done, the user credentials are added and ready to be used for authentication testing.

I also noticed that there are other parts in HttpContext you might require, such as the .MapPath() method. There is a FakeHttpContext available, which is described here and can be installed via NuGet.

The CSS content property along with ::after and ::before pseudo-elements have been introduced for this.

    content: 'ADD';
}

Data as factor can be used as input to the plot function.

An answer to a similar question has been given here: https://stat.ethz.ch/pipermail/r-help/2010-December/261873.html

 x=sample(c("Richard", "Minnie", "Albert", "Helen", "Joe", "Kingston"),  
 50, replace=T)
 x=as.factor(x)
 plot(x)

Missing a semicolon

if [ -a myApp ];
then
  rm myApp
fi

However, I assume you are checking for existence before deletion to prevent an error message. If so, you can just use rm -f myApp which "forces" delete, i.e. doesn't error out if the file didn't exist.

In JavaScript, null is a special singleton object which is helpful for signaling "no value". You can test for it by comparison and, as usual in JavaScript, it's a good practice to use the === operator to avoid confusing type coercion:

var a = null;
alert(a === null); // true

As @rynah mentions, "undefined" is a bit confusing in JavaScript. However, it's always safe to test if the typeof(x) is the string "undefined", even if "x" is not a declared variable:

alert(typeof(x) === 'undefined'); // true

Also, variables can have the "undefined value" if they are not initialized:

var y;
alert(typeof(y) === 'undefined'); // true

Putting it all together, your check should look like this:

if ((typeof(data) !== 'undefined') && (data !== null)) {
  // ...

However, since the variable "data" is always defined since it is a formal function parameter, using the "typeof" operator is unnecessary and you can safely compare directly with the "undefined value".

function(data) {
  if ((data !== undefined) && (data !== null)) {
    // ...

This snippet amounts to saying "if the function was called with an argument which is defined and is not null..."

Use Application.ActiveWorkbook.Path for just the path itself (without the workbook name) or Application.ActiveWorkbook.FullName for the path with the workbook name.

You can create a custom directive that is somehow similar to ng-disabled and disable a specific set of elements by:

1. watching the property changes of the custom directive, e.g. my-disabled.
2. clone the current element without the added event handlers.
3. add css properties to the cloned element and other attributes or event handlers that will provide the disabled state of an element.
4. when changes are detected on the watched property, replace the current element with the cloned element.

HTML

   <a my-disabled="disableCreate" href="#" ng-click="disableEdit = true">CREATE</a><br/>
   <a my-disabled="disableEdit" href="#" ng-click="disableCreate = true">EDIT</a><br/>
   <a my-disabled="disableCreate || disableEdit" href="#">DELETE</a><br/>
   <a href="#" ng-click="disableEdit = false; disableCreate = false;">RESET</a>

JAVASCRIPT

directive('myDisabled', function() {
  return {

    link: function(scope, elem, attr) {
      var color = elem.css('color'),
          textDecoration = elem.css('text-decoration'),
          cursor = elem.css('cursor'),
          // double negation for non-boolean attributes e.g. undefined
          currentValue = !!scope.$eval(attr.myDisabled),

          current = elem[0],
          next = elem[0].cloneNode(true);

      var nextElem = angular.element(next);

      nextElem.on('click', function(e) {
        e.preventDefault();
        e.stopPropagation();
      });

      nextElem.css('color', 'gray');
      nextElem.css('text-decoration', 'line-through');
      nextElem.css('cursor', 'not-allowed');
      nextElem.attr('tabindex', -1);

      scope.$watch(attr.myDisabled, function(value) {
        // double negation for non-boolean attributes e.g. undefined
        value = !!value;

        if(currentValue != value) {
          currentValue = value;
          current.parentNode.replaceChild(next, current);
          var temp = current;
          current = next;
          next = temp;
        }

      })
    }

The posted setdiff answer is nice. I just thought I'd post this related function I wrote a while back. Its usefulness is up to the reader :-).

lstype<-function(type='closure'){ 
    inlist<-ls(.GlobalEnv)
    if (type=='function') type <-'closure'
    typelist<-sapply(sapply(inlist,get),typeof)
    return(names(typelist[typelist==type]))
}

One more solution that I've discovered by accident, and may help someone:

1. Back up the corrupted workspace.
2. Move half of you projects to some temporary location.
3. Start Eclipse, if it works, go to step 5.
4. Move the half of projects you've removed back into the workspace, move out the other half. If you've already done that, keep removing/readding your projects in a binary search manner. Go to step 3.
5. Exit Eclipse, move back all your projects, and start it again. You should see now that some of your projects are closed (and in the wrong working sets). Re-open your projects and move them to the correct working sets.

In my case, it was a project that got corrupted, and not the entire workspace (attempting to import said project into a fresh workspace caused it to fail as well). So, I've started to search for the faulty project - instead, I got the result described above.

You can fix this problem by adding "$(ProjectDir)" (or wherever the stdafx.h is) to list of directories under Project->Properties->Configuration Properties->C/C++->General->Additional Include Directories.

After refactoring a little bit, this is an example of a complete windows service installer with automatic start:

using System.ComponentModel;
using System.Configuration.Install;
using System.ServiceProcess;

namespace Example.of.name.space
{
[RunInstaller(true)]
public partial class ServiceInstaller : Installer
{
    private readonly ServiceProcessInstaller processInstaller;
    private readonly System.ServiceProcess.ServiceInstaller serviceInstaller;

    public ServiceInstaller()
    {
        InitializeComponent();
        processInstaller = new ServiceProcessInstaller();
        serviceInstaller = new System.ServiceProcess.ServiceInstaller();

        // Service will run under system account
        processInstaller.Account = ServiceAccount.LocalSystem;

        // Service will have Automatic Start Type
        serviceInstaller.StartType = ServiceStartMode.Automatic;

        serviceInstaller.ServiceName = "Windows Automatic Start Service";

        Installers.Add(serviceInstaller);
        Installers.Add(processInstaller);
        serviceInstaller.AfterInstall += ServiceInstaller_AfterInstall;            
    }
    private void ServiceInstaller_AfterInstall(object sender, InstallEventArgs e)
    {
        ServiceController sc = new ServiceController("Windows Automatic Start Service");
        sc.Start();
    }
}
}

Here's what I use. If you just subtract the dates, it won't work across the Daylight Savings Time Boundary (eg April 1 to April 30 or Oct 1 to Oct 31). This drops all the hours to make sure you get a day and eliminates any DST problem by using UTC.

var nDays = (    Date.UTC(EndDate.getFullYear(), EndDate.getMonth(), EndDate.getDate()) -
                 Date.UTC(StartDate.getFullYear(), StartDate.getMonth(), StartDate.getDate())) / 86400000;

as a function:

function DaysBetween(StartDate, EndDate) {
  // The number of milliseconds in all UTC days (no DST)
  const oneDay = 1000 * 60 * 60 * 24;

  // A day in UTC always lasts 24 hours (unlike in other time formats)
  const start = Date.UTC(EndDate.getFullYear(), EndDate.getMonth(), EndDate.getDate());
  const end = Date.UTC(StartDate.getFullYear(), StartDate.getMonth(), StartDate.getDate());

  // so it's safe to divide by 24 hours
  return (start - end) / oneDay;
}

The Classloader API doesn't have an "enumerate" method, because class loading is an "on-demand" activity -- you usually have thousands of classes in your classpath, only a fraction of which will ever be needed (the rt.jar alone is 48MB nowadays!).

So, even if you could enumerate all classes, this would be very time- and memory-consuming.

The simple approach is to list the concerned classes in a setup file (xml or whatever suits your fancy); if you want to do this automatically, restrict yourself to one JAR or one class directory.

Most of the above suggestions technically aren't C++, they're C solutions.

Look into the use of std::stringstream.

Use this method (No need to xml file)

If you want scale to quarter(half x,half y)

view.animate().scaleX(0.5f).scaleY(0.5f)

If you want scale and move to bottom right

view.animate().scaleX(0.5f).scaleY(0.5f)
        .translationY((view.height/4).toFloat()).translationX((view.width/4).toFloat())

If you want move to top use (-view.height/4) and for left (-view.width/4)

If you want do something after animation ends use withEndAction(Runnable runnable) function.

You can use some other property like alpha and rotation

Full code

view.animate()
      .scaleX(0.5f).scaleY(0.5f)//scale to quarter(half x,half y)
      .translationY((view.height/4).toFloat()).translationX((view.width/4).toFloat())// move to bottom / right
      .alpha(0.5f) // make it less visible
      .rotation(360f) // one round turns
      .setDuration(1000) // all take 1 seconds
      .withEndAction(new Runnable() {
           @Override
           public void run() {
              //animation ended
           }
      });
