IMHO, the 'cleanest' way to select the First, visible, enabled text field on the page, is to use jQuery and do something like this:

$(document).ready(function() {
  $('input:text[value=""]:visible:enabled:first').focus();
});

Hope that helps...

Thanks...

Starting Mongo 4.2, db.collection.update() can accept an aggregation pipeline, which allows using aggregation operators such as $addFields, which outputs all existing fields from the input documents and newly added fields:

var new_info = { param2: "val2_new", param3: "val3_new" }

// { some_key: { param1: "val1", param2: "val2", param3: "val3" } }
// { some_key: { param1: "val1", param2: "val2"                 } }
db.collection.update({}, [{ $addFields: { some_key: new_info } }], { multi: true })
// { some_key: { param1: "val1", param2: "val2_new", param3: "val3_new" } }
// { some_key: { param1: "val1", param2: "val2_new", param3: "val3_new" } }

• The first part {} is the match query, filtering which documents to update (in this case all documents).

• The second part [{ $addFields: { some_key: new_info } }] is the update aggregation pipeline:

  • Note the squared brackets signifying the use of an aggregation pipeline.
  • Since this is an aggregation pipeline, we can use $addFields.
  • $addFields performs exactly what you need: updating the object so that the new object will overlay / merge with the existing one:
  • In this case, { param2: "val2_new", param3: "val3_new" } will be merged into the existing some_key by keeping param1 untouched and either add or replace both param2 and param3.

• Don't forget { multi: true }, otherwise only the first matching document will be updated.

You have to set to element_blank() in theme() elements you need to remove

ggplot(data = diamonds, mapping = aes(x = clarity)) + geom_bar(aes(fill = cut))+
  theme(axis.title.x=element_blank(),
        axis.text.x=element_blank(),
        axis.ticks.x=element_blank())

Another way ..

<img ng-src="{{!video.playing ? 'img/icons/play-rounded-button-outline.svg' : 'img/icons/pause-thin-rounded-button.svg'}}" />

Go to http://dev.mysql.com/downloads/connector/j and with in the dropdown select "Platform Independent" then it will show you the options to download tar.gz file or zip file.

Download zip file and extract it, with in that you will find mysql-connector-XXX.jar file

If you are using maven then you can add the dependency from the link http://mvnrepository.com/artifact/mysql/mysql-connector-java

Select the version you want to use and add the dependency in your pom.xml file

Complete set of special characters:

/[\!\@\#\$\%\^\&\*\)\(\+\=\.\<\>\{\}\[\]\:\;\'\"\|\~\`\_\-]/g

To answer your question:

As pointed by this the best way to obtain a concurrency-able HashSet is by means of Collections.synchronizedSet()

Set s = Collections.synchronizedSet(new HashSet(...));

This worked for me and I haven't seen anybody really pointing to it.

EDIT This is less efficient than the currently aproved solution, as Eugene points out, since it just wraps your set into a synchronized decorator, while a ConcurrentHashMap actually implements low-level concurrency and it can back your Set just as fine. So thanks to Mr. Stepanenkov for making that clear.

http://docs.oracle.com/javase/8/docs/api/java/util/Collections.html#synchronizedSet-java.util.Set-

Answering the first two points:

• GPS will always give you a more precise location, if it is enabled and if there are no thick walls around.

• If location did not change, then you can call getLastKnownLocation(String) and retrieve the location immediately.

Using an alternative approach:

You can try getting the cell id in use or all the neighboring cells

TelephonyManager mTelephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
GsmCellLocation loc = (GsmCellLocation) mTelephonyManager.getCellLocation(); 
Log.d ("CID", Integer.toString(loc.getCid()));
Log.d ("LAC", Integer.toString(loc.getLac()));
// or 
List<NeighboringCellInfo> list = mTelephonyManager.getNeighboringCellInfo ();
for (NeighboringCellInfo cell : list) {
    Log.d ("CID", Integer.toString(cell.getCid()));
    Log.d ("LAC", Integer.toString(cell.getLac()));
}

You can refer then to cell location through several open databases (e.g., http://www.location-api.com/ or http://opencellid.org/ )

The strategy would be to read the list of tower IDs when reading the location. Then, in next query (10 minutes in your app), read them again. If at least some towers are the same, then it's safe to use getLastKnownLocation(String). If they're not, then wait for onLocationChanged(). This avoids the need of a third party database for the location. You can also try this approach.

Let me clarify what you're talking about: you want to test Foo in a testcase, which calls external method uses_some_other_method. Instead of calling the actual method, you want to mock the return value.

class Foo:
    def method_1():
       results = uses_some_other_method()
    def method_n():
       results = uses_some_other_method()

Suppose the above code is in foo.py and uses_some_other_method is defined in module bar.py. Here is the unittest:

import unittest
import mock

from foo import Foo


class TestFoo(unittest.TestCase):

    def setup(self):
        self.foo = Foo()

    @mock.patch('foo.uses_some_other_method')
    def test_method_1(self, mock_method):
        mock_method.return_value = 3
        self.foo.method_1(*args, **kwargs)

        mock_method.assert_called_with(*args, **kwargs)

If you want to change the return value every time you passed in different arguments, mock provides side_effect.

I changes only two points

Obviously they were according to the version of the versions that it has, otherwise they would have to download them

• buil.gradle(Project)

  dependencies {
         classpath 'com.android.toolsg.build:gradle:2.3.2' 
         ..
  }
  

• gradle.wrapper.properties

  ...
  distributionUrl=https://services.gradle.org/distributions/gradle-3.3-all.zip

You can also use (focusout) event:

Use (eventName) for while binding event to DOM, basically () is used for event binding. Also you can use ngModel to get two way binding for your model. With the help of ngModel you can manipulate model variable value inside your component.

Do this in HTML file

<input type="text" [(ngModel)]="model" (focusout)="someMethodWithFocusOutEvent($event)">

And in your (component) .ts file

export class AppComponent { 
 model: any;
 constructor(){ }
 someMethodWithFocusOutEvent(){
   console.log('Your method called');
   // Do something here
 }
}

According to the packages list in Ubuntu Wily Xenial Bionic there is a package named openjfx. This should be a candidate for what you're looking for:

JavaFX/OpenJFX 8 - Rich client application platform for Java

You can install it via:

sudo apt-get install openjfx

It provides the following JAR files to the OpenJDK installation on Ubuntu systems:

/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/jfxrt.jar
/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/jfxswt.jar
/usr/lib/jvm/java-8-openjdk-amd64/lib/ant-javafx.jar
/usr/lib/jvm/java-8-openjdk-amd64/lib/javafx-mx.jar

If you want to have sources available, for example for debugging, you can additionally install:

sudo apt-get install openjfx-source

Make sure to enable the use of shortcodes in text widgets.

// To enable the use, add this in your *functions.php* file:
add_filter( 'widget_text', 'do_shortcode' );

// and then you can use it in any PHP file:  
<?php echo do_shortcode('[YOUR-SHORTCODE-NAME/TAG]'); ?>

Check the documentation for more.

The way I'm currently doing this is a bit shorter than those already suggested and as far as I can tell gives the desired result:

 var index = haystack.ToList().IndexOf(needle);

It's a bit clunky, but it does the job and is fairly concise.

What's dumpsys and what are its benefit

dumpsys is an android tool that runs on the device and dumps interesting information about the status of system services.

Obvious benefits:

1. Possibility to easily get system information in a simple string representation.
2. Possibility to use dumped CPU, RAM, Battery, storage stats for a pretty charts, which will allow you to check how your application affects the overall device!

What information can we retrieve from dumpsys shell command and how we can use it

If you run dumpsys you would see a ton of system information. But you can use only separate parts of this big dump.

to see all of the "subcommands" of dumpsys do:

dumpsys | grep "DUMP OF SERVICE"

dumpsys is ultimately flexible and useful tool!

If you want to use this tool do not forget to add permission into your android manifest automatically android.permission.DUMP

Try to test all commands to learn more about dumpsys. Happy dumping!

I was having the exact same problem. I found the issue within bootstrap.min.css. You need to change the label: label {display:inline-block;} to label {display:block;}

An inner class is a friend of the class it is defined within.
So, yes; an object of type Outer::Inner can access the member variable var of an object of type Outer.

Unlike Java though, there is no correlation between an object of type Outer::Inner and an object of the parent class. You have to make the parent child relationship manually.

#include <string>
#include <iostream>

class Outer
{
    class Inner
    {
        public:
            Inner(Outer& x): parent(x) {}
            void func()
            {
                std::string a = "myconst1";
                std::cout << parent.var << std::endl;

                if (a == MYCONST)
                {   std::cout << "string same" << std::endl;
                }
                else
                {   std::cout << "string not same" << std::endl;
                }
            }
        private:
            Outer&  parent;
    };

    public:
        Outer()
            :i(*this)
            ,var(4)
        {}
        Outer(Outer& other)
            :i(other)
            ,var(22)
        {}
        void func()
        {
            i.func();
        }
    private:
        static const char* const MYCONST;
        Inner i;
        int var;
};

const char* const Outer::MYCONST = "myconst";

int main()
{

    Outer           o1;
    Outer           o2(o1);
    o1.func();
    o2.func();
}

simply insert new line where necessary

sql="
SELECT c1, c2
from Table1, Table2
where ...
"

shell will be looking for the closing quotation mark

you can use winhttprequest object instead of internet explorer as it's good to load data excluding pictures n advertisement instead of downloading full webpage including advertisement n pictures those make internet explorer object heavy compare to winhttpRequest object.

For me, I was setting up a database with pgAdmin and it seems setting the owner during database creation was not enough. I had to navigate down to the 'public' schema and set the owner there as well (was originally 'postgres').

For Mac OS Users :

Go to your Android SDK folder and delete the tools folder (I recommend you to make a copy before deleting it, in case this solution does not solve the problem for you)

Then download the tools folder here :

http://dl-ssl.google.com/android/repository/tools_r25.2.5-macosx.zip

You can find all tools zip version here :

https://androidsdkoffline.blogspot.fr/p/android-sdk-build-tools.html

Then unzip the download file and place it in the Android sdk folder.

Hope it helps

nodejs domains is the most up to date way of handling errors in nodejs. Domains can capture both error/other events as well as traditionally thrown objects. Domains also provide functionality for handling callbacks with an error passed as the first argument via the intercept method.

As with normal try/catch-style error handling, is is usually best to throw errors when they occur, and block out areas where you want to isolate errors from affecting the rest of the code. The way to "block out" these areas are to call domain.run with a function as a block of isolated code.

In synchronous code, the above is enough - when an error happens you either let it be thrown through, or you catch it and handle there, reverting any data you need to revert.

try {  
  //something
} catch(e) {
  // handle data reversion
  // probably log too
}

When the error happens in an asynchronous callback, you either need to be able to fully handle the rollback of data (shared state, external data like databases, etc). OR you have to set something to indicate that an exception has happened - where ever you care about that flag, you have to wait for the callback to complete.

var err = null;
var d = require('domain').create();
d.on('error', function(e) {
  err = e;
  // any additional error handling
}
d.run(function() { Fiber(function() {
  // do stuff
  var future = somethingAsynchronous();
  // more stuff

  future.wait(); // here we care about the error
  if(err != null) {
    // handle data reversion
    // probably log too
  }

})});

Some of that above code is ugly, but you can create patterns for yourself to make it prettier, eg:

var specialDomain = specialDomain(function() {
  // do stuff
  var future = somethingAsynchronous();
  // more stuff

  future.wait(); // here we care about the error
  if(specialDomain.error()) {
    // handle data reversion
    // probably log too
  } 
}, function() { // "catch"
  // any additional error handling
});

UPDATE (2013-09):

Above, I use a future that implies fibers semantics, which allow you to wait on futures in-line. This actually allows you to use traditional try-catch blocks for everything - which I find to be the best way to go. However, you can't always do this (ie in the browser)...

There are also futures that don't require fibers semantics (which then work with normal, browsery JavaScript). These can be called futures, promises, or deferreds (I'll just refer to futures from here on). Plain-old-JavaScript futures libraries allow errors to be propagated between futures. Only some of these libraries allow any thrown future to be correctly handled, so beware.

An example:

returnsAFuture().then(function() {
  console.log('1')
  return doSomething() // also returns a future

}).then(function() {
  console.log('2')
  throw Error("oops an error was thrown")

}).then(function() {
  console.log('3')

}).catch(function(exception) {
  console.log('handler')
  // handle the exception
}).done()

This mimics a normal try-catch, even though the pieces are asynchronous. It would print:

1
2
handler

Note that it doesn't print '3' because an exception was thrown that interrupts that flow.

Take a look at bluebird promises:

• https://github.com/petkaantonov/bluebird

Note that I haven't found many other libraries other than these that properly handle thrown exceptions. jQuery's deferred, for example, don't - the "fail" handler would never get the exception thrown an a 'then' handler, which in my opinion is a deal breaker.

Strings are "immutable" for good reason: It really saves a lot of headaches, more often than you'd think. It also allows python to be very smart about optimizing their use. If you want to process your string in increments, you can pull out part of it with split() or separate it into two parts using indices:

a = "abc"
a, result = a[:-1], a[-1]

This shows that you're splitting your string in two. If you'll be examining every byte of the string, you can iterate over it (in reverse, if you wish):

for result in reversed(a):
    ...

I should add this seems a little contrived: Your string is more likely to have some separator, and then you'll use split:

ans = "foo,blah,etc."
for a in ans.split(","):
    ...

Check this page http://www.alanwood.net/unicode/geometric_shapes.html, first is "9650 ? 25B2 BLACK UP-POINTING TRIANGLE (present in WGL4)" and 2nd "9660 ? 25BC BLACK DOWN-POINTING TRIANGLE (present in WGL4)".

Entering a PIN is actually an outdated method of pairing, now called Legacy Pairing. Secure Simple Pairing Mode is available in Bluetooth v2.1 and later, which comprises most modern Bluetooth devices. SSPMode authentication is handled by the Bluetooth protocol stack and thus works without user interaction.

Here is how one might go about connecting to a device:

# hciconfig hci0 sspmode 1
# hciconfig hci0 sspmode
hci0:   Type: BR/EDR  Bus: USB
BD Address: AA:BB:CC:DD:EE:FF  ACL MTU: 1021:8  SCO MTU: 64:1
Simple Pairing mode: Enabled
# hciconfig hci0 piscan
# sdptool add SP
# hcitool scan
    00:11:22:33:44:55    My_Device
# rfcomm connect /dev/rfcomm0 00:11:22:33:44:55 1 &
Connected /dev/rfcomm0 to 00:11:22:33:44:55 on channel 1
Press CTRL-C for hangup

This would establish a serial connection to the device.

If you have just upgraded to SVN 1.7 on your machine (like I just did), and have a lot of projects in your Eclipse workspace which need to be upgraded, you can do the following in a terminal window on Unix-baesd systems:

cd [eclipse/workspace] # <- you supply the actual path here

for file in `find . -depth 2 -name "*.svn"`; do svn upgrade `dirname $file` ; done;

After Googling a bit, I found what seems to be the equivalent for Windows users:

http://www.rqna.net/qna/mnrmqn-how-to-find-all-svn-working-copies-on-win-xp.html

See the answer by Alexey Shcherbak halfway down the page.

All the answers above are correct, What I prefer is to use tui mode (ctrl+X A or 'tui enable') which shows your location and the function in a separate window which is very helpful for the users. Hope that helps too.

This is a newer answer to this excellent old question. From Hadley's Advanced R:

install.packages("pryr")

library(pryr)

object_size(1:10)

object_size(mean)
## 832 B

object_size(mtcars)
## 6.74 kB

Objects in python store their atributes (including functions) in a dict called __dict__. You can (but generally shouldn't) use this to access the attributes directly. If you just want a list, you can also call dir(obj), which returns an iterable with all the attribute names, which you could then pass to getattr.

However, needing to do anything with the names of the variables is usually bad design. Why not keep them in a collection?

class Foo(object):
    def __init__(self, **values):
        self.special_values = values

You can then iterate over the keys with for key in obj.special_values:

When working with youtube the floating elements give the value "0" as the scroll height so rather than using "return document.body.scrollHeight" try using this one "return document.documentElement.scrollHeight" adjust the scroll pause time as per your internet speed else it will run for only one time and then breaks after that.

SCROLL_PAUSE_TIME = 1

# Get scroll height
"""last_height = driver.execute_script("return document.body.scrollHeight")

this dowsnt work due to floating web elements on youtube
"""

last_height = driver.execute_script("return document.documentElement.scrollHeight")
while True:
    # Scroll down to bottom
    driver.execute_script("window.scrollTo(0,document.documentElement.scrollHeight);")

    # Wait to load page
    time.sleep(SCROLL_PAUSE_TIME)

    # Calculate new scroll height and compare with last scroll height
    new_height = driver.execute_script("return document.documentElement.scrollHeight")
    if new_height == last_height:
       print("break")
       break
    last_height = new_height

This worked for me.

Object.keys(myMap).map( key => {
    console.log("key: " + key);
    console.log("value: " + myMap[key]);
});

This is also an option

 for key, element := range myMap{
    fmt.Println("Key:", key, "Element:", element)
 }

Instead of the --target option or the --install-options option, I have found that the following works well (from discussion on a bug regarding this very thing at https://github.com/pypa/pip/issues/446):

PYTHONUSERBASE=/path/to/install/to pip install --user

(Or set the PYTHONUSERBASE directory in your environment before running the command, using export PYTHONUSERBASE=/path/to/install/to)

This uses the very useful --user option but tells it to make the bin, lib, share and other directories you'd expect under a custom prefix rather than $HOME/.local.

Then you can add this to your PATH, PYTHONPATH and other variables as you would a normal installation directory.

Note that you may also need to specify the --upgrade and --ignore-installed options if any packages upon which this depends require newer versions to be installed in the PYTHONUSERBASE directory, to override the system-provided versions.

A full example:

PYTHONUSERBASE=/opt/mysterypackage-1.0/python-deps pip install --user --upgrade numpy scipy

..to install the scipy and numpy package most recent versions into a directory which you can then include in your PYTHONPATH like so (using bash and for python 2.6 on CentOS 6 for this example):

export PYTHONPATH=/opt/mysterypackage-1.0/python-deps/lib64/python2.6/site-packages:$PYTHONPATH
export PATH=/opt/mysterypackage-1.0/python-deps/bin:$PATH

Using virtualenv is still a better and neater solution!

Do you want to iterate over characters or words?

For words, you'll have to split the words first, such as

for index, word in enumerate(loopme.split(" ")):
    print "CURRENT WORD IS", word, "AT INDEX", index

This prints the index of the word.

For the absolute character position you'd need something like

chars = 0
for index, word in enumerate(loopme.split(" ")):
    print "CURRENT WORD IS", word, "AT INDEX", index, "AND AT CHARACTER", chars
    chars += len(word) + 1

This:

STR_TO_DATE(t.datestring, '%d/%m/%Y')

...will convert the string into a datetime datatype. To be sure that it comes out in the format you desire, use DATE_FORMAT:

DATE_FORMAT(STR_TO_DATE(t.datestring, '%d/%m/%Y'), '%Y-%m-%d')

If you can't change the datatype on the original column, I suggest creating a view that uses the STR_TO_DATE call to convert the string to a DateTime data type.

You cannot use IF control block OUTSIDE of functions. So that affects both of your queries.

Turn the EXISTS clause into a subquery instead within an IF function

SELECT IF( EXISTS(
             SELECT *
             FROM gdata_calendars
             WHERE `group` =  ? AND id = ?), 1, 0)

In fact, booleans are returned as 1 or 0

SELECT EXISTS(
         SELECT *
         FROM gdata_calendars
         WHERE `group` =  ? AND id = ?)

You need to double escape any RegExp characters (once for the slash in the string and once for the regexp):

  "$TESTONE $TESTONE".replace( new RegExp("\\$TESTONE","gm"),"foo")

Otherwise, it looks for the end of the line and 'TESTONE' (which it never finds).

Personally, I'm not a big fan of building regexp's using strings for this reason. The level of escaping that's needed could lead you to drink. I'm sure others feel differently though and like drinking when writing regexes.

The NSDictionary and NSMutableDictionary docs are probably your best bet. They even have some great examples on how to do various things, like...

...create an NSDictionary

NSArray *keys = [NSArray arrayWithObjects:@"key1", @"key2", nil];
NSArray *objects = [NSArray arrayWithObjects:@"value1", @"value2", nil];
NSDictionary *dictionary = [NSDictionary dictionaryWithObjects:objects 
                                                       forKeys:keys];

...iterate over it

for (id key in dictionary) {
    NSLog(@"key: %@, value: %@", key, [dictionary objectForKey:key]);
}

...make it mutable

NSMutableDictionary *mutableDict = [dictionary mutableCopy];

Note: historic version before 2010: [[dictionary mutableCopy] autorelease]

...and alter it

[mutableDict setObject:@"value3" forKey:@"key3"];

...then store it to a file

[mutableDict writeToFile:@"path/to/file" atomically:YES];

...and read it back again

NSMutableDictionary *anotherDict = [NSMutableDictionary dictionaryWithContentsOfFile:@"path/to/file"];

...read a value

NSString *x = [anotherDict objectForKey:@"key1"];

...check if a key exists

if ( [anotherDict objectForKey:@"key999"] == nil ) NSLog(@"that key is not there");

...use scary futuristic syntax

From 2014 you can actually just type dict[@"key"] rather than [dict objectForKey:@"key"]

Override the controllers Json/JsonResult to return JSON.Net:

This works a treat

Use Java's replaceAll(String regex, String replacement)

For example, Use a substitution char for the quotes and then replace that char with \"

String newstring = String.replaceAll("%","\"");

or replace all instances of \" with \\\"

String newstring = String.replaceAll("\"","\\\"");

I tried the code and in my case the code below solve the issue. I had not settled the schema properly

@Entity
    @Table(name="table"
         ,catalog="databasename"
      )

Please try to add ,catalog="databasename" the same as I did.

,catalog="databasename"

You can add a PPA that provides a relatively current version of SmartGit(as well as SmartGitHg, the predecessor of SmartGit).

To add the PPA run:

sudo add-apt-repository ppa:eugenesan/ppa
sudo apt-get update

To install smartgit (after adding the PPA) run:

sudo apt-get install smartgit

To install smartgithg (after adding the PPA) run:

sudo apt-get install smartgithg

This should add a menu option for you

This answer didn't work for me, but I found the answer myself. No one, however, has posted my question. I'm too lazy to ask it and then answer it, so will just put it here.

This is for the following query:

data = Leaderboard.objects.filter(id=custom_user.id).values(
    'value1',
    'value2',
    'value3')

In template:

{% for dictionary in data %}
  {% for key, value in dictionary.items %}
    <p>{{ key }} : {{ value }}</p>
  {% endfor %}
{% endfor %}

Here's a kludgy way to get the output from another powershell process:

start-process -wait -nonewwindow powershell 'ps | Export-Clixml out.xml'; import-clixml out.xml

You could make the element containing the bg text have a lower stacking order ( z-index, position ) and possibly even set opacity. So the element you need on top would need a higher stacking order ( z-index:5; position:relative; for ex ) and the element behind would need something lower ( default or just a lower z-index like 3 and position:relative; ).

Sometimes this error occurs when UserAgent request parameter is empty (in github.com api in my case).

Setting this parameter to custom not empty string solved my problem.

The 3rd option is to create a "Policy" table, then a "SectionsMain" table that stores all of the fields that are in common across the types of sections. Then create other tables for each type of section that only contain the fields that are not in common.

Deciding which is best depends mostly on how many fields you have and how you want to write your SQL. They would all work. If you have just a few fields then I would probably go with #1. With "lots" of fields I would lean towards #2 or #3.

print("single",end=" ")
print("line")

this will give output

single line

for the question asked use

i = 0 
while i <10:
     i += 1 
     print (i,end="")

This is because those handlers do not preserve scope. From react documentation: react documentation

Check the "no autobinding" section. You should write the handler like: onClick = () => {}

$result = mysql_query($query) or die("Data not found."); 
$rows=array(); 
while($r=mysql_fetch_assoc($result))
{ 
$rows[]=$r;
}
header("Content-type:application/json"); 
echo json_encode($rows);

Update November 2020

A website is now online with all the TSDoc syntax available (and that's awesome): https://tsdoc.org/

For reference, old answer:

The right syntax is now the one used by TSDoc. It will allow you to have your comments understood by Visual Studio Code or other documentation tools.

Note: you should not use JSDoc, as explained on TSDoc main page: Why can't JSDoc be the standard? Unfortunately, the JSDoc grammar is not rigorously specified but rather inferred from the behavior of a particular implementation. The majority of the standard JSDoc tags are preoccupied with providing type annotations for plain JavaScript, which is an irrelevant concern for a strongly-typed language such as TypeScript. TSDoc addresses these limitations while also tackling a more sophisticated set of goals.

By default it's logged into system log at /var/log/syslog, so it can be read by:

tail -f /var/log/syslog

If the file doesn't exist, check /etc/syslog.conf to see configuration file for syslogd. Note that the configuration file could be different, so check the running process if it's using different file:

# ps wuax | grep syslog
root      /sbin/syslogd -f /etc/syslog-knoppix.conf

^{Note: In some distributions (such as Knoppix) all logged messages could be sent into different terminal (e.g. /dev/tty12), so to access e.g. tty12 try pressing Control+Alt+F12.}

You can also use lsof tool to find out which log file the syslogd process is using, e.g.

sudo lsof -p $(pgrep syslog) | grep log$ 

To send the test message to syslogd in shell, you may try:

echo test | logger

For troubleshooting use a trace tool (strace on Linux, dtruss on Unix), e.g.:

sudo strace -fp $(cat /var/run/syslogd.pid)

Look at java.lang.BigDecimal, may solve your problem.

IF you want to derive usg Boolean true False need to add "[]" around value

<form [formGroup]="form">
  <input type="radio" [value]=true formControlName="gender" >Male
  <input type="radio" [value]=false formControlName="gender">Female
</form>

Not sure if the most efficient way, but this worked for me:

from pyspark.sql.functions import col

df1.alias('a').join(df2.alias('b'),col('b.id') == col('a.id')).select([col('a.'+xx) for xx in a.columns] + [col('b.other1'),col('b.other2')])

The trick is in:

[col('a.'+xx) for xx in a.columns] : all columns in a

[col('b.other1'),col('b.other2')] : some columns of b

I've seen some very creative answers, but you can just do this (for global packages add the --global switch):

npm ls package

Example:

npm ls babel-cli
`-- [email protected]

The npm documentation says that npm -ls

This command will print to stdout all the versions of packages that are installed, as well as their dependencies, in a tree-structure.

NPM documentation

In case you are looking for a cut and paste method that creates and writes to a file, here's one I wrote that just takes a String input. Remove 'true' from PrintWriter if you want to overwrite the file each time.

private static final String newLine = System.getProperty("line.separator");

private synchronized void writeToFile(String msg)  {
    String fileName = "c:\\TEMP\\runOutput.txt";
    PrintWriter printWriter = null;
    File file = new File(fileName);
    try {
        if (!file.exists()) file.createNewFile();
        printWriter = new PrintWriter(new FileOutputStream(fileName, true));
        printWriter.write(newLine + msg);
    } catch (IOException ioex) {
        ioex.printStackTrace();
    } finally {
        if (printWriter != null) {
            printWriter.flush();
            printWriter.close();
        }
    }
}

Try this

SELECT CONCAT('"',GROUP_CONCAT(id),'"') FROM table_level 
where parent_id=4 group by parent_id;

Result will be

 "5,6,9,10,12,14,15,17,18,779"

I recommend Charles Web Proxy

Charles is an HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet. This includes requests, responses and the HTTP headers (which contain the cookies and caching information).

• SSL Proxying – view SSL requests and responses in plain text
• Bandwidth Throttling to simulate slower Internet connections including latency
• AJAX debugging – view XML and JSON requests and responses as a tree or as text
• AMF – view the contents of Flash Remoting / Flex Remoting messages as a tree
• Repeat requests to test back-end changes, Edit requests to test different inputs
• Breakpoints to intercept and edit requests or responses
• Validate recorded HTML, CSS and RSS/atom responses using the W3C validator

It's cross-platform, written in JAVA, and pretty good. Not nearly as overwhelming as Wireshark, and does a lot of the annoying stuff like setting up the proxies, etc. for you. The only bad part is that it costs money, $50 at that. Not cheap, but a useful tool.

Read more about Charles's features.

When N is very large, the normal method that randomly shuffles the N numbers and selects, say, first k numbers, can be prohibitive because of space complexity. The following algorithm requires only O(k) for both time and space complexities.

http://arxiv.org/abs/1512.00501

def random_selection_indices(num_samples, N):
    modified_entries = {}
    seq = []
    for n in xrange(num_samples):
        i = N - n - 1
        j = random.randrange(i)

        # swap a[j] and a[i] 
        a_j = modified_entries[j] if j in modified_entries else j 
        a_i = modified_entries[i] if i in modified_entries else i

        if a_i != j:
            modified_entries[j] = a_i   
        elif j in modified_entries:   # no need to store the modified value if it is the same as index
            modified_entries.pop(j)

        if a_j != i:
            modified_entries[i] = a_j 
        elif i in modified_entries:   # no need to store the modified value if it is the same as index
            modified_entries.pop(i)
        seq.append(a_j)
    return seq

About generating the same random number if you call it in a loop a nifty solution is to declare the new Random() object outside of the loop as a global variable.

Notice that you have to declare your instance of the Random class outside of the GetRandomInt function if you are going to be running this in a loop.

“Why is this?” you ask.

Well, the Random class actually generates pseudo random numbers, with the “seed” for the randomizer being the system time. If your loop is sufficiently fast, the system clock time will not appear different to the randomizer and each new instance of the Random class would start off with the same seed and give you the same pseudo random number.

I would give a min-height and min-width to your overlay div of the size of the image, and change the background color on hover

.overlay { position: absolute; top: 0; left: 0;  z-index: 200; min-height:200px; min-width:200px; background-color: none;}
.overlay:hover { background-color: red;}

JAVA_HOME = C:\Program Files\Java\jdk(JDK version number)

$("meta")

Should give you back an array of elements whose tag name is META and then you can iterate over the collection to pick out whatever attributes of the elements you are interested in.

The answer of this question depends on the number of items and their size and your budget. Depends on that we have following 3 cases:

1- The number of items and size of items in the table are not very much. then as Steffen Opel said you can Use Query rather than Scan to retrieve all items for user_id and then loop over all returned items and either facilitate DeleteItem or BatchWriteItem. But keep in mind you may burn a lot of throughput capacity here. For example, consider a situation where you need delete 1000 items from a DynamoDB table. Assume that each item is 1 KB in size, resulting in Around 1MB of data. This bulk-deleting task will require a total of 2000 write capacity units for query and delete. To perform this data load within 10 seconds (which is not even considered as fast in some applications), you would need to set the provisioned write throughput of the table to 200 write capacity units. As you can see its doable to use this way if its for less number of items or small size items.

2- We have a lot of items or very large items in the table and we can store them according to the time into different tables. Then as jonathan Said you can just delete the table. this is much better but I don't think it is matched with your case. As you want to delete all of users data no matter what is the time of creation of logs, so in this case you can't delete a particular table. if you wanna have a separate table for each user then I guess if number of users are high then its so expensive and it is not practical for your case.

3- If you have a lot of data and you can't divide your hot and cold data into different tables and you need to do large scale delete frequently then unfortunately DynamoDB is not a good option for you at all. It may become more expensive or very slow(depends on your budget). In these cases I recommend to find another database for your data.

It works fine for me, but it's a little tricky :)

• First open the PuTTY configuration.
• Select the session (right part of the window, Saved Sessions)
• Click Load (now you have loaded Host Name, Port and Connection type)
• Then click Logging (under Session on the left)
• Change whatever settings you want
• Go back to Session window and click the Save button

Now you have settings for this session set (every time you load session it will be logged).

If you are using debug configuration for maven, use the command

clean install

And skip all the tests.

How to put MySQL functions back into PHP 7
Step 1

First get the mysql extension source which was removed in March:

https://github.com/php/php-src/tree/PRE_PHP7_EREG_MYSQL_REMOVALS/ext/mysql

Step 2

Then edit your php.ini

Somewhere either in the “Extensions” section or “MySQL” section, simply add this line:

extension = /usr/local/lib/php/extensions/no-debug-non-zts-20141001/mysql.so

Step 3

Restart PHP and mysql_* functions should now be working again.

Step 4

Turn off all deprecated warnings including them from mysql_*:

error_reporting(E_ALL ^ E_DEPRECATED);

Now Below Code Help You :

$result = mysql_query("SELECT names FROM Customers");
$Data= Array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) 
{
        $Data[] =  $row['names'];  
}

You can also get all values in column using mysql_fetch_assoc

$result = mysql_query("SELECT names FROM Customers");
    $Data= Array();
    while ($row = mysql_fetch_assoc($result)) 
    {
            $Data[] =  $row['names'];  
    }

This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used.

YOU CAN USE MYSQLI ALTERNATIVE OF MYSQL EASY WAY

*

<?php
$con=mysqli_connect("localhost","my_user","my_password","my_db");
// Check connection
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }

$sql="SELECT Lastname,Age FROM Persons ORDER BY Lastname";
$result=mysqli_query($con,$sql);

// Numeric array
$row=mysqli_fetch_array($result,MYSQLI_NUM);
printf ("%s (%s)\n",$row[0],$row[1]);

// Associative array
$row=mysqli_fetch_array($result,MYSQLI_ASSOC);
printf ("%s (%s)\n",$row["Lastname"],$row["Age"]);

// Free result set
mysqli_free_result($result);

mysqli_close($con);
?> 

If you need just to execute your VLC playback process and only give control back to your application process when it is done and nothing more complex, then i suppose you can use just:

system("The same thing you type into console");

just .idea/ works fine for me

I just had this problem. This is what worked for me:

pip install botocore==1.13.20

In WPF, you can now simply do:

Mouse.OverrideCursor = System.Windows.Input.Cursors.Wait; // set the cursor to loading spinner

Mouse.OverrideCursor = System.Windows.Input.Cursors.Arrow; // set the cursor back to arrow

As of version 11, Opera supports linear gradients with the -o- vendor prefix. Chris Mills wrote a Dev.Opera article about it: http://dev.opera.com/articles/view/css3-linear-gradients/

Radial gradients are still in the works (both in the spec, and within Opera).

Here's an implementation using node-http-proxy from nodejitsu.

var http = require('http');
var httpProxy = require('http-proxy');
var proxy = httpProxy.createProxyServer({});

http.createServer(function(req, res) {
    proxy.web(req, res, { target: 'http://www.google.com' });
}).listen(3000);

the only solution for me was:

click on window->close all perspective (you can try also close perspective)

after this, in the top right corner click on: open perspective->resource

Superkey - An attribute or set of attributes that uniquely defines a tuple within a relation. However, a superkey may contain additional attributes that are not necessary for unique identification.

Candidate key - A superkey such that no proper subset is a superkey within the relation. So, basically has two properties: Each candidate key uniquely identifies tuple in the relation ; & no proper subset of the composite key has the uniqueness property.

Composite key - When a candidate key consists of more than one attribute.

Primary key - The candidate key chosen to identify tuples uniquely within the relation.

Alternate key - Candidate key that is not a primary key.

Foreign key - An attribute or set of attributes within a relation that matches the candidate key of some relation.

Try this Code

List itemStates = new List();

for (int i = 0; i < 10; i++)
{ 
    itemStates.Add(new ItemState { Id = i.ToString() });
    dataGridView1.DataSource = itemStates;
    dataGridView1.DataBind();
    System.Threading.Thread.Sleep(500);
}

This can be a good option if you want python completion as well as other languages. https://github.com/Valloric/YouCompleteMe

The python completion is jedi based same as jedi-vim.

I use:

cat /home/path/to/dump/file | psql -h localhost -U <user_name> -d <db_name>

Hope this will help someone.

But still, the memory address for each letter in this address is different.

Memory address is different but as its array of characters they are sequential. When you pass address of first element and use %s, printf will print all characters starting from given address until it finds '\0'.

None of the above solutions worked for me on Windows 8

But the following command works fine

SHIFT + Q

As mentioned in other people's comments, the top solution given here was not working for me in Ansible 2.2, particularly when also using with_items.

It appears that OP's intended approach does work now with a slight change to the quoting of item.

- set_fact: something="{{ something + [ item ] }}"
  with_items:
    - one
    - two
    - three

And a longer example where I've handled the initial case of the list being undefined and added an optional when because that was also causing me grief:

- set_fact: something="{{ something|default([]) + [ item ] }}"
  with_items:
    - one
    - two
    - three
  when: item.name in allowed_things.item_list

I think you could just use class "col-md-12" it has required left and right paddings and 100% width. Looks like this is a good replacement for container-fluid from 2nd bootstrap.

I prefer use a pure MySQL syntax to get last auto_increment id of the table I want.

php mysql_insert_id() and mysql last_insert_id() give only last transaction ID.

If you want last auto_incremented ID of any table in your schema (not only last transaction one), you can use this query

SELECT AUTO_INCREMENT FROM information_schema.TABLES
    WHERE TABLE_SCHEMA = 'my_database' 
    AND TABLE_NAME = 'my_table_name';

That's it.

I know this question is 4-5 years old, but still, this might be useful:

Sometimes, if you have only a few elements that "exit the screen", the list might not scroll. That's because the operating system doesn't view it as actually exceeding the screen.

I'm saying this because I ran into this problem today - I only had 2 or 3 elements that were exceeding the screen limits, and my list wasn't scrollable. And it was a real mystery. As soon as I added a few more, it started to scroll.

So you have to make sure it's not a design problem at first, like the list appearing to go beyond the borders of the screen but in reality, "it doesn't", and adjust its dimensions and margin values and see if it's starting to "become scrollable". It did, for me.

Why write custom jQuery code for Marquee... just use a plugin for jQuery - marquee() and use it like in the example below:

First include :

<script type='text/javascript' src='//cdn.jsdelivr.net/jquery.marquee/1.3.1/jquery.marquee.min.js'></script>

and then:

//proporcional speed counter (for responsive/fluid use)
var widths = $('.marquee').width()
var duration = widths * 7;

$('.marquee').marquee({
    //speed in milliseconds of the marquee
    duration: duration, // for responsive/fluid use
    //duration: 8000, // for fixed container
    //gap in pixels between the tickers
    gap: $('.marquee').width(),
    //time in milliseconds before the marquee will start animating
    delayBeforeStart: 0,
    //'left' or 'right'
    direction: 'left',
    //true or false - should the marquee be duplicated to show an effect of continues flow
    duplicated: true
});

If you can make it simpler and better I dare you all people :). Don't make your life more difficult than it should be. More about this plugin and its functionalities at: http://aamirafridi.com/jquery/jquery-marquee-plugin

Resizing canvas using css is not a good idea. It should be done using Javascript. See the below function which does it

function setCanvas(){

   var canvasNode = document.getElementById('xCanvas');

   var pw = canvasNode.parentNode.clientWidth;
   var ph = canvasNode.parentNode.clientHeight;

   canvasNode.height = pw * 0.8 * (canvasNode.height/canvasNode.width);  
   canvasNode.width = pw * 0.8;
   canvasNode.style.top = (ph-canvasNode.height)/2 + "px";
   canvasNode.style.left = (pw-canvasNode.width)/2 + "px";


}

git-pull - Fetch from and integrate with another repository or a local branch

git pull [options] [<repository> [<refspec>...]]

You can refer official git doc https://git-scm.com/docs/git-pull

Ex :

git pull origin dev

 $.ajax({
    type: "POST",
    data: formData,
    url: "/Forms/GetJobData",
    dataType: 'json',
    contentType: false,
    processData: false,               
    success: function (response) {
        if (response.success) {
            alert(response.responseText);
        } else {
            // DoSomethingElse()
            alert(response.responseText);
        }                          
    },
    error: function (response) {
        alert("error!");  // 
    }

});

Controller:

[HttpPost]
public ActionResult GetJobData(Jobs jobData)
{
    var mimeType = jobData.File.ContentType;
    var isFileSupported = IsFileSupported(mimeType);

    if (!isFileSupported){        
         //  Send "false"
        return Json(new { success = false, responseText = "The attached file is not supported." }, JsonRequestBehavior.AllowGet);
    }
    else
    {
        //  Send "Success"
        return Json(new { success = true, responseText= "Your message successfuly sent!"}, JsonRequestBehavior.AllowGet);
    }   
}

---Supplement:---

basically you can send multiple parameters this way:

Controller:

 return Json(new { 
                success = true,
                Name = model.Name,
                Phone = model.Phone,
                Email = model.Email                                
            }, 
            JsonRequestBehavior.AllowGet);

Html:

<script> 
     $.ajax({
                type: "POST",
                url: '@Url.Action("GetData")',
                contentType: 'application/json; charset=utf-8',            
                success: function (response) {

                   if(response.success){ 
                      console.log(response.Name);
                      console.log(response.Phone);
                      console.log(response.Email);
                    }


                },
                error: function (response) {
                    alert("error!"); 
                }
            });

You can comment section of a script using a conditional.

For example, the following script:

DEBUG=false
if ${DEBUG}; then
echo 1
echo 2
echo 3
echo 4
echo 5
fi
echo 6
echo 7

would output:

6
7

In order to uncomment the section of the code, you simply need to comment the variable:

#DEBUG=false

(Doing so would print the numbers 1 through 7.)

isset vs. !empty

FTA:

"isset() checks if a variable has a value including (False, 0 or empty string), but not NULL. Returns TRUE if var exists; FALSE otherwise.

On the other hand the empty() function checks if the variable has an empty value empty string, 0, NULL or False. Returns FALSE if var has a non-empty and non-zero value."

You need to have a SQLite JDBC driver in your classpath.

Taro L. Saito (xerial) forked the Zentus project and now maintains it under the name sqlite-jdbc. It bundles the native drivers for major platforms so you don't need to configure them separately.

For me deleting the derived data fixed it , I noticed even if I check out from an old commit, the same issue happens.

You can reach that option form Window-> Projects .

Or you can use this javascript

$(function () {
    $("#projectKey").change(function () {
        alert($('#projectKey option:selected').text());
    });
});

this method helped me.

MY FAVORITE WAY TO DO IT

1. Open info.plist

2. Click this button to add a new key

3. Scroll down to find Privacy - Photo Library Usage Description

4. Select it, then add your description on the right

DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
  Date date1 = null;
  Date date2 = null;

  try {
    date1 = dateFormat.parse(t1);
    date2 = dateFormat.parse(t2);
  } catch (ParseException e) {
    e.printStackTrace();
  }
  DateFormat formatter = new SimpleDateFormat("dd-MMM-yyyy");
  String StDate = formatter.format(date1);
  String edDate = formatter.format(date2);

  System.out.println("ST  "+ StDate);
  System.out.println("ED "+ edDate);

In pymongo you can update with:
mycollection.update({'_id':mongo_id}, {"$set": post}, upsert=False)
Upsert parameter will insert instead of updating if the post is not found in the database.
Documentation is available at mongodb site.

UPDATE For version > 3 use update_one instead of update:

mycollection.update_one({'_id':mongo_id}, {"$set": post}, upsert=False)

If you have directory listing disabled in your webserver, then the only way somebody will find it is by guessing or by finding a link to it.

That said, I've seen hacking scripts attempt to "guess" a whole bunch of these common names. "secret.html" would probably be in such a guess list.

The more reasonable solution is to restrict access using a username/password via a htaccess file (for apache) or the equivalent setting for whatever webserver you're using.

What solved it for me:

• Open a terminal window
• cd into YOUR_PROJECT/ios
• Remove the build folder with rm -r build
• Run react-native run-ios again

Alternatively, you could open Finder, navigate to YOUR_PROJECT/ios and delete the build folder.

Then run react-native run-ios again.

You can try openSSL to generate certificates. Take a look at this.

You are going to need a .key and .crt file to add HTTPS to node JS express server. Once you generate this, use this code to add HTTPS to server.

var https = require('https');
var fs = require('fs');
var express = require('express');

var options = {
    key: fs.readFileSync('/etc/apache2/ssl/server.key'),
    cert: fs.readFileSync('/etc/apache2/ssl/server.crt'),
    requestCert: false,
    rejectUnauthorized: false
};


var app = express();

var server = https.createServer(options, app).listen(3000, function(){
    console.log("server started at port 3000");
});

This is working fine in my local machine as well as the server where I have deployed this. The one I have in server was bought from goDaddy but localhost had a self signed certificate.

However, every browser threw an error saying connection is not trusted, do you want to continue. After I click continue, it worked fine.

If anyone has ever bypassed this error with self signed certificate, please enlighten.

How to use

Create a new TimeSpan object

    const ts = TimeSpan.zero;

    const milliseconds = 10000; // 1 second

    // by using the constructor
    const ts1 = new TimeSpan(milliseconds);

    // or as an alternative you can use the static factory method
    const ts2 = TimeSpan.fromMilliseconds(milliseconds);

    const seconds = 86400; // 1 day
    const ts = TimeSpan.fromSeconds(seconds);

    const minutes = 1440; // 1 day
    const ts = TimeSpan.fromMinutes(minutes);

    const hours = 24; // 1 day
    const ts = TimeSpan.fromHours(hours);

    const days = 1; // 1 day
    const ts = TimeSpan.fromDays(days);

    const hours = 1;
    const minutes = 1;
    const seconds = 1;
    const ts = TimeSpan.fromTime(hours, minutes, seconds);

    const days = 1;
    const hours = 1;
    const minutes = 1;
    const seconds = 1;
    const milliseconds = 1;
    const ts = TimeSpan.fromTime(days, hours, minutes, seconds, milliseconds);

    const ts = TimeSpan.maxValue;

    const ts = TimeSpan.minValue;

    const ts = TimeSpan.minValue;

    const ts1 = TimeSpan.fromDays(1);
    const ts2 = TimeSpan.fromHours(1);
    const ts = ts1.add(ts2);

    console.log(ts.days);               // 1
    console.log(ts.hours);              // 1
    console.log(ts.minutes);            // 0
    console.log(ts.seconds);            // 0
    console.log(ts.milliseconds);           // 0

    const ts1 = TimeSpan.fromDays(1);
    const ts2 = TimeSpan.fromHours(1);
    const ts = ts1.subtract(ts2);

    console.log(ts.days);               // 0
    console.log(ts.hours);              // 23
    console.log(ts.minutes);            // 0
    console.log(ts.seconds);            // 0
    console.log(ts.milliseconds);           // 0

    const days = 1;
    const hours = 1;
    const minutes = 1;
    const seconds = 1;
    const milliseconds = 1;
    const ts = TimeSpan.fromTime2(days, hours, minutes, seconds, milliseconds);

    console.log(ts.days);               // 1
    console.log(ts.hours);              // 1
    console.log(ts.minutes);            // 1
    console.log(ts.seconds);            // 1
    console.log(ts.milliseconds);           // 1

    console.log(ts.totalDays)           // 1.0423726967592593;
    console.log(ts.totalHours)          // 25.016944722222224;
    console.log(ts.totalMinutes)            // 1501.0166833333333;
    console.log(ts.totalSeconds)            // 90061.001;
    console.log(ts.totalMilliseconds);      // 90061001;

You could try using ES7 async/await. For instance using your example:

handleChange: async function(event) {
    console.log(this.state.value);
    await this.setState({value: event.target.value});
    console.log(this.state.value);
}

You should be able to accomplish this by adding a refspec for tags to your local config. Concretely:

[remote "upstream"]
    url = <redacted>
    fetch = +refs/heads/*:refs/remotes/upstream/*
    fetch = +refs/tags/*:refs/tags/*

The css properties max-width and max-height work great, but aren't supported by IE6 and I believe IE7. You would want to use this over height / width so you don't accidentally scale an image up. You would just want to limit the maximum height/width proportionately.

I know this question is over 6 years old, but still, I would like to share my method using tables and this won't require any CSS.

<table><tr><td><img src="loading.gif"></td><td> Loading...</td></tr></table>

Cheers! Happy Coding

You're missing a FROM and you need to give the subquery an alias.

SELECT COUNT(*) FROM 
(
  SELECT DISTINCT a.my_id, a.last_name, a.first_name, b.temp_val
   FROM dbo.Table_A AS a 
   INNER JOIN dbo.Table_B AS b 
   ON a.a_id = b.a_id
) AS subquery;

First of all, when you put that code in applicationDidFinishLaunching, it might be the case that controllers instantiated from Interface Builder are not yet linked to your application (so "red" and "blue" are still nil).

But to answer your initial question, what you're doing wrong is that you're calling dismissModalViewControllerAnimated: on the wrong controller! It should be like this:

[blue presentModalViewController:red animated:YES];
[red dismissModalViewControllerAnimated:YES];

Usually the "red" controller should decide to dismiss himself at some point (maybe when a "cancel" button is clicked). Then the "red" controller could call the method on self:

[self dismissModalViewControllerAnimated:YES];

If it still doesn't work, it might have something to do with the fact that the controller is presented in an animation fashion, so you might not be allowed to dismiss the controller so soon after presenting it.

By the looks of it you need to actually pass drawImage an image object like so

var canvas = document.getElementById("c");_x000D_
var ctx = canvas.getContext("2d");_x000D_
_x000D_
var image = new Image();_x000D_

Are you sure that the XML file is in the correct character encoding? FileReader always uses the platform default encoding, so if the "working" server had a default encoding of (say) ISO-8859-1 and the "problem" server uses UTF-8 you would see this error if the XML contains any non-ASCII characters.

Does it work if you create the InputSource from a FileInputStream instead of a FileReader?

You need to put the last() indexing on the nodelist result, rather than as part of the selection criteria. Try:

(//element[@name='D'])[last()]

SELECT * FROM table where Date(col) = 'date'

Just put the below simple code :

notification.sound = Uri.parse("android.resource://"
        + context.getPackageName() + "/" + R.raw.sound_file);

For Default Sound:

notification.defaults |= Notification.DEFAULT_SOUND;

It is more efficient to send the files directly.

The base64 encoding of Content-Type: multipart/form-data adds an extra 33% overhead. If the server supports it, it is more efficient to send the files directly:

Doing Multiple $http.post Requests Directly from a FileList

$scope.upload = function(url, fileList) {
    var config = {
      headers: { 'Content-Type': undefined },
      transformResponse: angular.identity
    };
    var promises = fileList.map(function(file) {
      return $http.post(url, file, config);
    });
    return $q.all(promises);
};

When sending a POST with a File object, it is important to set 'Content-Type': undefined. The XHR send method will then detect the File object and automatically set the content type.

Working Demo of "select-ng-files" Directive that Works with ng-model¹

The <input type=file> element does not by default work with the ng-model directive. It needs a custom directive:

angular.module("app",[]);

angular.module("app").directive("selectNgFiles", function() {
  return {
    require: "ngModel",
    link: function postLink(scope,elem,attrs,ngModel) {
      elem.on("change", function(e) {
        var files = elem[0].files;
        ngModel.$setViewValue(files);
      })
    }
  }
});

<script src="//unpkg.com/angular/angular.js"></script>
  <body ng-app="app">
    <h1>AngularJS Input `type=file` Demo</h1>
    
    <input type="file" select-ng-files ng-model="fileList" multiple>
    
    <h2>Files</h2>
    <div ng-repeat="file in fileList">

I'm not using IIS Express but developing against my Local Full IIS 7.

So if anyone else get's here trying to do that, I had to add the mime type for woff via IIS Manager

Mime Types >> Click Add link on right and then enter Extension: .woff MIME type: application/font-woff

simply "CUT" project folder and move it out of workspace directory and do the following

file=>import=>(select new directory)=> mark (copy to my workspace) checkbox 

and you done !

Any best practices here?

Use the Maven advanced reactor options, more specifically:

-pl, --projects
        Build specified reactor projects instead of all projects
-am, --also-make
        If project list is specified, also build projects required by the list

So just cd into the parent P directory and run:

mvn install -pl B -am

And this will build B and the modules required by B.

Note that you need to use a colon if you are referencing an artifactId which differs from the directory name:

mvn install -pl :B -am

Basic program of adding two times:
You can modify hour:min:sec as per your need using if else.
This program shows you how you can add values from two objects and return in another object.

class demo
{private int hour,min,sec;
    void input(int hour,int min,int sec)
    {this.hour=hour;
    this.min=min;
    this.sec=sec;

    }
    demo add(demo d2)//demo  because we are returning object
    {   demo obj=new demo();
    obj.hour=hour+d2.hour;
    obj.min=min+d2.min;
    obj.sec=sec+d2.sec;
    return obj;//Returning object and later on it gets allocated to demo d3                    
    }
    void display()
    {
        System.out.println(hour+":"+min+":"+sec);
    }
    public static  void main(String args[])
    {
        demo d1=new demo();
        demo d2=new demo();
        d1.input(2, 5, 10);
        d2.input(3, 3, 3);
        demo d3=d1.add(d2);//Note another object is created
        d3.display();


    }

}

Modified Time Addition Program

 class demo
{private int hour,min,sec;
void input(int hour,int min,int sec)
{this.hour=(hour>12&&hour<24)?(hour-12):hour;
this.min=(min>60)?0:min;
this.sec=(sec>60)?0:sec;
}
demo add(demo d2)
{ demo obj=new demo();
obj.hour=hour+d2.hour;
obj.min=min+d2.min;
obj.sec=sec+d2.sec;
if(obj.sec>60)
{obj.sec-=60;
obj.min++;
}
if(obj.min>60)
{ obj.min-=60;
obj.hour++;
}
return obj;
}
void display()
{
System.out.println(hour+":"+min+":"+sec);
}
public static void main(String args[])
{
demo d1=new demo();
demo d2=new demo();
d1.input(12, 55, 55);
d2.input(12, 7, 6);
demo d3=d1.add(d2);
d3.display();
}
}

In my case, this error:

Video format or MIME type is not supported.

Was due to the CSP in my .htaccess that did not allow the content to be loaded. You can check this by opening the browser's console and refreshing the page.

Once I added the domain that was hosting the video in the media-src part of that CSP, the console was clean and the video was loaded properly. Example:

Content-Security-Policy: default-src 'none'; media-src https://myvideohost.domain; script-src 'self'; style-src 'unsafe-inline' 'self'

AFAIK, there is no method that does this in the framework. Even if there was support for something like this in the framework, it would essentially be doing the same thing. And that would be looking at each cell in the DataRow to see if it is empty.

If you have no concrete implementations of the class and the methods aren't static whats the point of testing them? If you have a concrete class then you'll be testing those methods as part of the concrete class's public API.

I know what you are thinking "I don't want to test these methods over and over thats the reason I created the abstract class", but my counter argument to that is that the point of unit tests is to allow developers to make changes, run the tests, and analyze the results. Part of those changes could include overriding your abstract class's methods, both protected and public, which could result in fundamental behavioral changes. Depending on the nature of those changes it could affect how your application runs in unexpected, possibly negative ways. If you have a good unit testing suite problems arising from these types changes should be apparent at development time.

• Open build.gradle for library project

• Write two tasks in build.gradle -- deleteJar and createJar and add rule createJar.dependsOn(deleteJar, build)

The code from above:

task deleteJar(type: Delete) {
    delete 'libs/jars/logmanagementlib.jar'
}           

task createJar(type: Copy) {
    from('build/intermediates/bundles/release/')
    into('libs/jars/')
    include('classes.jar')
    rename('classes.jar', 'logmanagementlib.jar')
}

createJar.dependsOn(deleteJar, build)

• Expand gradle panel from right and open all tasks under yourlibrary->others. You will see two new tasks there -- createJar and deleteJar

• Double click on createJar

• Once the task run successfully, get your generated jar from path mentioned in createJar task i.e. libs/xxxx.jar

• copy the newly generated jar into your required project's lib folder-->right click-->select "add as library"

Your file seems quite small (297 lines) so you can read and write them quite quickly. You refer to Excel CSV, which does not exists, and you show space delimited data in your example. Furthermore, Access is limited to 255 columns, and a CSV is not, so there is no guarantee this will work

Sub StripHeaderAndFooter()
Dim fs As Object ''FileSystemObject
Dim tsIn As Object, tsOut As Object ''TextStream
Dim sFileIn As String, sFileOut As String
Dim aryFile As Variant

    sFileIn = "z:\docs\FileName.csv"
    sFileOut = "z:\docs\FileOut.csv"

    Set fs = CreateObject("Scripting.FileSystemObject")
    Set tsIn = fs.OpenTextFile(sFileIn, 1) ''ForReading

    sTmp = tsIn.ReadAll

    Set tsOut = fs.CreateTextFile(sFileOut, True) ''Overwrite
    aryFile = Split(sTmp, vbCrLf)

    ''Start at line 3 and end at last line -1
    For i = 3 To UBound(aryFile) - 1
        tsOut.WriteLine aryFile(i)
    Next

    tsOut.Close

    DoCmd.TransferText acImportDelim, , "NewCSV", sFileOut, False
End Sub

Edit re various comments

It is possible to import a text file manually into MS Access and this will allow you to choose you own cell delimiters and text delimiters. You need to choose External data from the menu, select your file and step through the wizard.

About importing and linking data and database objects -- Applies to: Microsoft Office Access 2003

Introduction to importing and exporting data -- Applies to: Microsoft Access 2010

Once you get the import working using the wizards, you can save an import specification and use it for you next DoCmd.TransferText as outlined by @Olivier Jacot-Descombes. This will allow you to have non-standard delimiters such as semi colon and single-quoted text.

Technically there aren't actually any "remote" things at all¹ in your Git repo, there are just local names that should correspond to the names on another, different repo. The ones named origin/whatever will initially match up with those on the repo you cloned-from:

git clone ssh://some.where.out.there/some/path/to/repo # or git://some.where...

makes a local copy of the other repo. Along the way it notes all the branches that were there, and the commits those refer-to, and sticks those into your local repo under the names refs/remotes/origin/.

Depending on how long you go before you git fetch or equivalent to update "my copy of what's some.where.out.there", they may change their branches around, create new ones, and delete some. When you do your git fetch (or git pull which is really fetch plus merge), your repo will make copies of their new work and change all the refs/remotes/origin/<name> entries as needed. It's that moment of fetching that makes everything match up (well, that, and the initial clone, and some cases of pushing too—basically whenever Git gets a chance to check—but see caveat below).

Git normally has you refer to your own refs/heads/<name> as just <name>, and the remote ones as origin/<name>, and it all just works because it's obvious which one is which. It's sometimes possible to create your own branch names that make it not obvious, but don't worry about that until it happens. :-) Just give Git the shortest name that makes it obvious, and it will go from there: origin/master is "where master was over there last time I checked", and master is "where master is over here based on what I have been doing". Run git fetch to update Git on "where master is over there" as needed.

Caveat: in versions of Git older than 1.8.4, git fetch has some modes that don't update "where master is over there" (more precisely, modes that don't update any remote-tracking branches). Running git fetch origin, or git fetch --all, or even just git fetch, does update. Running git fetch origin master doesn't. Unfortunately, this "doesn't update" mode is triggered by ordinary git pull. (This is mainly just a minor annoyance and is fixed in Git 1.8.4 and later.)

¹Well, there is one thing that is called a "remote". But that's also local! The name origin is the thing Git calls "a remote". It's basically just a short name for the URL you used when you did the clone. It's also where the origin in origin/master comes from. The name origin/master is called a remote-tracking branch, which sometimes gets shortened to "remote branch", especially in older or more informal documentation.

Create a PHP file outside your document root. If your document root is

/var/www/html/

create the a file named minify.php one level above it

/var/www/minify.php

Copy paste the following PHP code into it

<?php
function minify_output($buffer){
    $search = array('/\>[^\S ]+/s','/[^\S ]+\</s','/(\s)+/s');
    $replace = array('>','<','\\1');
    if (preg_match("/\<html/i",$buffer) == 1 && preg_match("/\<\/html\>/i",$buffer) == 1) {
        $buffer = preg_replace($search, $replace, $buffer);
    }
    return $buffer;
}
ob_start("minify_output");?>

Save the minify.php file and open the php.ini file. If it is a dedicated server/VPS search for the following option, on shared hosting with custom php.ini add it.

auto_prepend_file = /var/www/minify.php

I suggest that you make a .gitignore file that includes everything other than the assets folder (all the other files that are originally inside a unity project). Next, you should place all your game projects in one folder. Next, duplicate the .gitignore in every single project folder for your games. This will exclude the libraries and unnecessary folders inside your projects other than the assets. If you have any projects you don't want, then put them in a new .gitignore inside where your game projects are stored. Note: You can have multiple .gitignore's and .gitignore is based on relative paths. I hope that helped!

Your workaround actually just saved me. I was having a lot of problems processing the request using the Falcon framework. This worked for me. req being the request form curl pr httpie

json.loads(req.stream.read().decode('utf-8'))

.nextInt() gets the next int, but doesn't read the new line character. This means that when you ask it to read the "next line", you read til the end of the new line character from the first time.

You can insert another .nextLine() after you get the int to fix this. Or (I prefer this way), read the int in as a string, and parse it to an int.

in SQL*Plus you could also use a REFCURSOR variable:

SQL> VARIABLE x REFCURSOR
SQL> DECLARE
  2   V_Sqlstatement Varchar2(2000);
  3  BEGIN
  4   V_Sqlstatement := 'SELECT * FROM DUAL';
  5   OPEN :x for v_Sqlstatement;
  6  End;
  7  /

I think it's an rather easy task to explain.

At first callback are just ordinary functions.
And the further is, that we call this function (let's call it A) from inside another function (let's call it B).

The magic about this is that I decide, which function should be called by the function from outside B.

At the time I write the function B I don't know which callback function should be called. At the time I call function B I also tell this function to call function A. That is all.

I think it's better to use ng-if. ng-show creates an element in the dom and sets it's display:none. The more dom elements you have the more resource hungry your app becomes, and on devices with lower resources the less dom elements the better.

TBH <span ng-if="!$last">, </span> seems like a great way to do it. It's simple.

Here's the code from Marc Gravell's answer, along with an example of using it.

using System;
using System.Collections.Generic;
using System.Linq;

public static class Utils
{
    public static bool IsAny<T>(this IEnumerable<T> data)
    {
        return data != null && data.Any();
    }
}

class Program
{
    static void Main(string[] args)
    {
        IEnumerable<string> items;
        //items = null;
        //items = new String[0];
        items = new String[] { "foo", "bar", "baz" };

        /*** Example Starts Here ***/
        if (items.IsAny())
        {
            foreach (var item in items)
            {
                Console.WriteLine(item);
            }
        }
        else
        {
            Console.WriteLine("No items.");
        }
    }
}

As he says, not all sequences are repeatable, so that code may sometimes cause problems, because IsAny() starts stepping through the sequence. I suspect what Robert Harvey's answer meant was that you often don't need to check for null and empty. Often, you can just check for null and then use foreach.

To avoid starting the sequence twice and take advantage of foreach, I just wrote some code like this:

using System;
using System.Collections.Generic;
using System.Linq;

class Program
{
    static void Main(string[] args)
    {
        IEnumerable<string> items;
        //items = null;
        //items = new String[0];
        items = new String[] { "foo", "bar", "baz" };

        /*** Example Starts Here ***/
        bool isEmpty = true;
        if (items != null)
        {
            foreach (var item in items)
            {
                isEmpty = false;
                Console.WriteLine(item);
            }
        }
        if (isEmpty)
        {
            Console.WriteLine("No items.");
        }
    }
}

I guess the extension method saves you a couple of lines of typing, but this code seems clearer to me. I suspect that some developers wouldn't immediately realize that IsAny(items) will actually start stepping through the sequence. (Of course if you're using a lot of sequences, you quickly learn to think about what steps through them.)

I know this is old, but here is a additional thing if you still encounter problems with the solution above.

Just put in your <head> :

<meta http-equiv="X-UA-Compatible" content="IE=edge"> 

It will prevent IE to jump back to IE9 compatibility, thus breaking the video function. Worked for me, so if you still have problems, consider checking this out.

Alternatively you can add this in PHP :

header('x-ua-compatible: ie=edge');

Or in a .htaccess file:

header set X-UA-Compatible "IE=Edge"

Make sure that the htaccess file is readable by apache:

chmod 644 /var/www/abc/.htaccess 

And make sure the directory it's in is readable and executable:

chmod 755 /var/www/abc/

if you want to bookkeep some variable before page refresh

$(window).on('beforeunload', function(){
    // your logic here
});

if you want o load some content base on some condition

$(window).on('load', function(){
    // your logic here`enter code here`
});

Launch the Terminal application and enter the following command after the prompt

  openssl pkcs12 -in CertificateName.p12 -out CertificateName.pem -nodes

PDFBox is the best library I've found for this purpose, it's comprehensive and really quite easy to use if you're just doing basic text extraction. Examples can be found here.

It explains it on the page, but one thing to watch out for is that the start and end indexes when using setStartPage() and setEndPage() are both inclusive. I skipped over that explanation first time round and then it took me a while to realise why I was getting more than one page back with each call!

Itext is another alternative that also works with C#, though I've personally never used it. It's more low level than PDFBox, so less suited to the job if all you need is basic text extraction.

I believe that using a combination of interfaces and base classes could work for you. It will enforce behavioral requirements at compile time (rq_ post "below" refers to a post above, which is not this one).

The interface sets the behavioral API that isn't met by the base class. You will not be able to set base class methods to call on methods defined in the interface (because you will not be able to implement that interface in the base class without having to define those behaviors). Maybe someone can come up with a safe trick to allow calling of the interface methods in the parent.

You have to remember to extend and implement in the class you will instantiate. It satisfies concerns about defining runtime-fail code. You also won't even be able to call the methods that would puke if you haven't implemented the interface (such as if you try to instantiate the Animal class). I tried having the interface extend the BaseAnimal below, but it hid the constructor and the 'name' field of BaseAnimal from Snake. If I had been able to do that, the use of a module and exports could have prevented accidental direct instantiation of the BaseAnimal class.

Paste this in here to see if it works for you: http://www.typescriptlang.org/Playground/

// The behavioral interface also needs to extend base for substitutability
interface AbstractAnimal extends BaseAnimal {
    // encapsulates animal behaviors that must be implemented
    makeSound(input : string): string;
}

class BaseAnimal {
    constructor(public name) { }

    move(meters) {
        alert(this.name + " moved " + meters + "m.");
    }
}

// If concrete class doesn't extend both, it cannot use super methods.
class Snake extends BaseAnimal implements AbstractAnimal {
    constructor(name) { super(name); }
    makeSound(input : string): string {
        var utterance = "sssss"+input;
        alert(utterance);
        return utterance;
    }
    move() {
        alert("Slithering...");
        super.move(5);
    }
}

var longMover = new Snake("windy man");

longMover.makeSound("...am I nothing?");
longMover.move();

var fulture = new BaseAnimal("bob fossil");
// compile error on makeSound() because it is not defined.
// fulture.makeSound("you know, like a...")
fulture.move(1);

I came across FristvanCampen's answer as linked below. He says abstract classes are an anti-pattern, and suggests that one instantiate base 'abstract' classes using an injected instance of an implementing class. This is fair, but there are counter arguments made. Read for yourself: https://typescript.codeplex.com/discussions/449920

Part 2: I had another case where I wanted an abstract class, but I was prevented from using my solution above, because the defined methods in the "abstract class" needed to refer to the methods defined in the matching interface. So, I tool FristvanCampen's advice, sort of. I have the incomplete "abstract" class, with method implementations. I have the interface with the unimplemented methods; this interface extends the "abstract" class. I then have a class that extends the first and implements the second (it must extend both because the super constructor is inaccessible otherwise). See the (non-runnable) sample below:

export class OntologyConceptFilter extends FilterWidget.FilterWidget<ConceptGraph.Node, ConceptGraph.Link> implements FilterWidget.IFilterWidget<ConceptGraph.Node, ConceptGraph.Link> {

    subMenuTitle = "Ontologies Rendered"; // overload or overshadow?

    constructor(
        public conceptGraph: ConceptGraph.ConceptGraph,
        graphView: PathToRoot.ConceptPathsToRoot,
        implementation: FilterWidget.IFilterWidget<ConceptGraph.Node, ConceptGraph.Link>
        ){
        super(graphView);
        this.implementation = this;
    }
}

and

export class FilterWidget<N extends GraphView.BaseNode, L extends GraphView.BaseLink<GraphView.BaseNode>> {

    public implementation: IFilterWidget<N, L>

    filterContainer: JQuery;

    public subMenuTitle : string; // Given value in children

    constructor(
        public graphView: GraphView.GraphView<N, L>
        ){

    }

    doStuff(node: N){
        this.implementation.generateStuff(thing);
    }

}

export interface IFilterWidget<N extends GraphView.BaseNode, L extends GraphView.BaseLink<GraphView.BaseNode>> extends FilterWidget<N, L> {

    generateStuff(node: N): string;

}

Disabled elements "eat" clicks in some browsers - they neither respond to them, nor allow them to be captured by event handlers anywhere on either the element or any of its containers.

IMHO the simplest, cleanest way to "fix" this (if you do in fact need to capture clicks on disabled elements like the OP does) is just to add the following CSS to your page:

input[disabled] {pointer-events:none}

This will make any clicks on a disabled input fall through to the parent element, where you can capture them normally. (If you have several disabled inputs, you might want to put each into an individual container of its own, if they aren't already laid out that way - an extra <span> or a <div>, say - just to make it easy to distinguish which disabled input was clicked).

The downside is that this trick unfortunately won't works for older browsers that don't support the pointer-events CSS property. (It should work from IE 11, FF v3.6, Chrome v4): caniuse.com/#search=pointer-events

If you need to support older browsers, you'll need to use one of the other answers!

I used to have exactly the same problem, and finally it was solved.

I put all the dependent DLLs into the same folder where mylib.dll was stored and make sure the JAVA Compiler could find it (if there is no mylib.dll in the compilation path, there would be an error reporting this during compiling). The important thing you need to notice is you must make sure all the dependent libs are of the same version with mylib.dll, for example if your mylib.dll is release version then you should also put the release version of all its dependent libs there.

Hope this could help others who have encountered the same problem.

There are known issues with IE and Opera not removing session cookies when setting the expire date to the past (which is what the jQuery cookie plugin does)

This works fine in Safari and Mozilla/FireFox.

You can use termcolor for this:

 sudo pip install termcolor

To print a colored bold:

 from termcolor import colored
 print(colored('Hello', 'green', attrs=['bold']))

For more information, see termcolor on PyPi.

simple-colors is another package with similar syntax:

 from simple_colors import *
 print(green('Hello', ['bold'])

The equivalent in colorama may be Style.BRIGHT.

Try this code:

bool appNotRestarted = true;

This code must also be in the function:

if (appNotRestarted == true) {
    appNotRestarted = false;
    Application.Restart();
    Application.ExitThread();
}

Several things here.

First off, you're defining your CSS in 3 places!

In line, in the head and externally. I suggest you only choose one. I'm going to suggest externally.

I suggest you update your code in your ASP form from

<td style="background-color: #A3A3A3; color: #FFFFFF; font-family: 'Arial Black'; font-size: large; font-weight: bold;" 
        class="style6">

to this:

<td  class="style6">

And then update your css too

.style6
    {
        height: 79px; background-color: #A3A3A3; color: #FFFFFF; font-family: 'Arial Black'; font-size: large; font-weight: bold;
    }

This removes the inline.

Now, to move it from the head of the webForm.

CROSS APPLY was the method I used for my solution, as it worked for me, and for my clients needs. And from what I've read, should provide the best overall performance should their database grow substantially.

Hello, World!

Use the builtin function zip():

In Python 3:

z = list(zip(x,y))

In Python 2:

z = zip(x,y)

I have been having this issue with SweetAlert2 as well. SA2 differs from 1 and puts everything inside the result object. The following above can be accomplished with the following code.

Swal.fire({
    title: 'A cool title',
    icon: 'info',
    confirmButtonText: 'Log in'
  }).then((result) => {
    if (result['isConfirmed']){
      // Put your function here
    }
  })

Everything placed inside the then result will run. Result holds a couple of parameters which can be used to do the trick. Pretty simple technique. Not sure if it works the same on SweetAlert1 but I really wouldn't know why you would choose that one above the newer version.

I know i went here 7 months late, but I found this questions and it looks interesting. I tried this on my browser console.

try{x,true}catch(e){false}

If variable x is undefined, error is catched and it will be false, if not, it will return true. So you can use eval function to set the value to a variable

var isxdefined = eval('try{x,true}catch(e){false}')

Yes but Thinking that you can program every kind of program in a single language is a flawed idea unless you are writing very simple programs. Objective C is for Cocoa as C# is for .NET, Use the right tool for right job, Trying to make C++ interact to Cocoa via writing bridging code and trying to make C++ code behave according to Cocoa requirements is not a good idea neither expecting C++ performance from Objective C is. You should try to layout design and architecture of app keeping in view existing skills and determine which part should be written in which language then build accordingly.

Maybe some AJAX page content injection could be used as an alternative, though I still can't get around why your teacher would refuse to rid the website of frames.

Additionally, is there any specific reason you personally want to us HTML5?

But if not, I believe <iframe>s are still around.

you can do it like this:

<script>
    function SomeDeleteRowFunction(o) {
     //no clue what to put here?
     var p=o.parentNode.parentNode;
         p.parentNode.removeChild(p);
    }
    </script>

    <table>
       <tr>
           <td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this)"></td>
       </tr>
       <tr>
           <td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this)"></td>
       </tr>
       <tr>
           <td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this)"></td>
       </tr>
    </table>

No. They did not include that in ECMAScript:

ECMAScript has no goto statement.

All your statements are valid except your first statement (after the Java 8 release):

Methods of a Java interface are implicitly abstract and cannot have implementations

From the documentation page:

An interface is a reference type, similar to a class, that can contain only constants, method signatures, default methods, static methods,and nested types

Method bodies exist only for default methods and static methods.

Default methods:

An interface can have default methods, but are different than abstract methods in abstract classes.

Default methods enable you to add new functionality to the interfaces of your libraries and ensure binary compatibility with code written for older versions of those interfaces.

When you extend an interface that contains a default method, you can do the following:

1. Not mention the default method at all, which lets your extended interface inherit the default method.
2. Redeclare the default method, which makes it abstract.
3. Redefine the default method, which overrides it.

Static Methods:

In addition to default methods, you can define static methods in interfaces. (A static method is a method that is associated with the class in which it is defined rather than with any object. Every instance of the class shares its static methods.)

This makes it easier for you to organize helper methods in your libraries;

Example code from documentation page about interface having static and default methods.

import java.time.*;

public interface TimeClient {
    void setTime(int hour, int minute, int second);
    void setDate(int day, int month, int year);
    void setDateAndTime(int day, int month, int year,
                               int hour, int minute, int second);
    LocalDateTime getLocalDateTime();

    static ZoneId getZoneId (String zoneString) {
        try {
            return ZoneId.of(zoneString);
        } catch (DateTimeException e) {
            System.err.println("Invalid time zone: " + zoneString +
                "; using default time zone instead.");
            return ZoneId.systemDefault();
        }
    }

    default ZonedDateTime getZonedDateTime(String zoneString) {
        return ZonedDateTime.of(getLocalDateTime(), getZoneId(zoneString));
    }
}

Use the below guidelines to chose whether to use an interface or abstract class.

Interface:

1. To define a contract ( preferably stateless - I mean no variables )
2. To link unrelated classes with has a capabilities.
3. To declare public constant variables (immutable state)

Abstract class:

1. Share code among several closely related classes. It establishes is a relation.

2. Share common state among related classes ( state can be modified in concrete classes)

Related posts:

Interface vs Abstract Class (general OO)

Implements vs extends: When to use? What's the difference?

By going through these examples, you can understand that

Unrelated classes can have capabilities through interface but related classes change the behaviour through extension of base classes.

I think, there is something wrong with PHP configration.
First, debug your database connection using this script at the end of ./config/database.php :

...
  ...
  ...
  echo '<pre>';
  print_r($db['default']);
  echo '</pre>';

  echo 'Connecting to database: ' .$db['default']['database'];
  $dbh=mysql_connect
  (
    $db['default']['hostname'],
    $db['default']['username'],
    $db['default']['password'])
    or die('Cannot connect to the database because: ' . mysql_error());
    mysql_select_db ($db['default']['database']);

    echo '<br />   Connected OK:'  ;
    die( 'file: ' .__FILE__ . ' Line: ' .__LINE__); 

Then see what the problem is.

You can hide navigation bar, just call this method on your onCreate(),

 public void FullScreencall() {
    if(Build.VERSION.SDK_INT < 19){ 
        View v = this.getWindow().getDecorView();
        v.setSystemUiVisibility(View.GONE);
    } else {
            //for higher api versions.    
        View decorView = getWindow().getDecorView(); 
        int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
        decorView.setSystemUiVisibility(uiOptions);
    }
}

This will hide whole nagiation panel.hope it helps you

In order to match a list of different categories of file, you can use the filter like this:

        var dlg = new Microsoft.Win32.OpenFileDialog()
        {
            DefaultExt = ".xlsx",
            Filter = "Excel Files (*.xls, *.xlsx)|*.xls;*.xlsx|CSV Files (*.csv)|*.csv"
        };

You could try installing the 32 bit version of opencv

For a simple array, you have the union approach, but you can also use :

_.uniq([2, 1, 2]);

I was using the following lines in my .ssh/config (which can be replaced by suitable command line parameters) under Ubuntu

Host remhost
  HostName      my.host.com
  User          myuser
  ProxyCommand  nc -v -X 5 -x proxy-ip:1080 %h %p 2> ssh-err.log
  ServerAliveInterval 30
  ForwardX11 yes

When using it with Msys2, after installing gnu-netcat, file ssh-err.log showed that option -X does not exist. nc --help confirmed that, and seemed to show that there is no alternative option to handle proxies.

So I installed openbsd-netcat (pacman removed gnu-netcat after asking, since it conflicted with openbsd-netcat). On a first view, and checking the respective man pages, openbsd-netcat and Ubuntu netcat seem to very similar, in particular regarding options -X and -x. With this, I connected with no problems.

Expanding on @Ryan G mentioned usage of the pandas.DataFrame.astype(<type>) method, one can use the errors=ignore argument to only convert those columns that do not produce an error, which notably simplifies the syntax. Obviously, caution should be applied when ignoring errors, but for this task it comes very handy.

>>> df = pd.DataFrame(np.random.rand(3, 4), columns=list('ABCD'))
>>> df *= 10
>>> print(df)
...           A       B       C       D
... 0   2.16861 8.34139 1.83434 6.91706
... 1   5.85938 9.71712 5.53371 4.26542
... 2   0.50112 4.06725 1.99795 4.75698

>>> df['E'] = list('XYZ')
>>> df.astype(int, errors='ignore')
>>> print(df)
...     A   B   C   D   E
... 0   2   8   1   6   X
... 1   5   9   5   4   Y
... 2   0   4   1   4   Z

From pandas.DataFrame.astype docs:

errors : {‘raise’, ‘ignore’}, default ‘raise’

Control raising of exceptions on invalid data for provided dtype.

• raise : allow exceptions to be raised
• ignore : suppress exceptions. On error return original object

New in version 0.20.0.

define a String variable using the JSP tags

<%!
String test = new String();
%>

then refer to that variable in your loop as

<c:forEach items="${myParams.items}" var="currentItem" varStatus="stat">
test+= whaterver_value
</c:forEach>

You just need to set background and give previous.xml file in background of button in your layout file.

<Button
 android:id="@+id/button1"
 android:background="@drawable/previous"
 android:layout_width="200dp"
 android:layout_height="126dp"
 android:text="Hello" />

and done.Edit Following is previous.xml file in drawable directory

<?xml version="1.0" encoding="utf-8"?>

<item android:drawable="@drawable/onclick" android:state_selected="true"></item>
<item android:drawable="@drawable/onclick" android:state_pressed="true"></item>
<item android:drawable="@drawable/normal"></item>

It depends on the way your page behaves. If you want this to happens asynchronously, you have to use AJAX. Try out "jQuery post()" on Google to find some tuts.

In other case, if this will happen when a user submits a form, you can send the variable in an hidden field or append ?variableName=someValue" to then end of the URL you are opening. :

http://www.somesite.com/send.php?variableName=someValue

or

http://www.somesite.com/send.php?variableName=someValue&anotherVariable=anotherValue

This way, from PHP you can access this value as:

$phpVariableName = $_POST["variableName"];

for forms using POST method or:

$phpVariableName = $_GET["variableName"];

for forms using GET method or the append to url method I've mentioned above (querystring).

This simplest ways is to add the "checked attribute.

<label for="tag_1">Tag 1</label>
<input type="checkbox" name="tag_1" id="tag_1" value="yes" 
    <?php if($tag_1_saved_value === 'yes') echo 'checked="checked"';?> />

Sun's JVM needs contiguous memory. So the maximal amount of available memory is dictated by memory fragmentation. Especially driver's dlls tend to fragment the memory, when loading into some predefined base address. So your hardware and its drivers determine how much memory you can get.

Two sources for this with statements from Sun engineers: forum blog

Maybe another JVM? Have you tried Harmony? I think they planned to allow non-continuous memory.

If you do decide to have MySQL handle the update of timestamps, you can set up a trigger to update the field on insert.

CREATE TRIGGER <trigger_name> BEFORE INSERT ON <table_name> FOR EACH ROW SET NEW.<timestamp_field> = CURRENT_TIMESTAMP;

MySQL Reference: http://dev.mysql.com/doc/refman/5.0/en/triggers.html

The best solution for this is to create a simple parent pom file project (with packaging 'pom') generically for all projects from your organization.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>

            <url>http://central_nexus/server</url>
        </repository>
    </distributionManagement>

</project>

This can be built, released, and deployed to your local nexus so everyone has access to its artifact.

Now for all projects which you wish to use it, simply include this section:

<parent>
  <groupId>your.company</groupId>
  <artifactId>company-parent</artifactId>
  <version>1.0.0</version>
</parent>

This solution will allow you to easily add other common things to all your company's projects. For instance if you wanted to standardize your JUnit usage to a specific version, this would be the perfect place for that.

If you have projects that use multi-module structures that have their own parent, Maven also supports chaining inheritance so it is perfectly acceptable to make your project's parent pom file refer to your company's parent pom and have the project's child modules not even aware of your company's parent.

I see from your example project structure that you are attempting to put your parent project at the same level as your aggregator pom. If your project needs its own parent, the best approach I have found is to include the parent at the same level as the rest of the modules and have your aggregator pom.xml file at the root of where all your modules' directories exist.

- pom.xml (aggregator)
    - project-parent
    - project-module1
    - project-module2

What you do with this structure is include your parent module in the aggregator and build everything with a mvn install from the root directory.

We use this exact solution at my organization and it has stood the test of time and worked quite well for us.

I made a small test project with just a UITextField and this code

#import <UIKit/UIKit.h>
@interface TextFieldTestViewController : UIViewController
<UITextFieldDelegate>
{
    UITextField *textField;
}
@property (nonatomic, retain) IBOutlet UITextField *textField;
@end

#import "TextFieldTestViewController.h"
@implementation TextFieldTestViewController
@synthesize textField;

- (void)viewDidLoad
{
    [self.textField setDelegate:self];
    [self.textField setReturnKeyType:UIReturnKeyDone];
    [self.textField addTarget:self
                  action:@selector(textFieldFinished:)
        forControlEvents:UIControlEventEditingDidEndOnExit];
    [super viewDidLoad];
}
- (IBAction)textFieldFinished:(id)sender
{
    // [sender resignFirstResponder];
}

- (void)dealloc {
    [super dealloc];
}
@end

The text field is an unmodified UITextField dragged onto the NIB, with the outlet connected.
After loading the app, clicking in the text field brings up the keyboard. Pressing the "Done" button makes the text field lose focus and animates out the keyboard. Note that the advice around the web is to always use [sender resignFirstResponder] but this works without it.

Try this to validate HTTP URLs (uriName is the URI you want to test):

Uri uriResult;
bool result = Uri.TryCreate(uriName, UriKind.Absolute, out uriResult) 
    && uriResult.Scheme == Uri.UriSchemeHttp;

Or, if you want to accept both HTTP and HTTPS URLs as valid (per J0e3gan's comment):

Uri uriResult;
bool result = Uri.TryCreate(uriName, UriKind.Absolute, out uriResult) 
    && (uriResult.Scheme == Uri.UriSchemeHttp || uriResult.Scheme == Uri.UriSchemeHttps);

Try oobash.

It is an OO-style string library for Bash 4. It has support for German umlauts. It is written in Bash.

Many functions are available: -base64Decode, -base64Encode, -capitalize, -center, -charAt, -concat, -contains, -count, -endsWith, -equals, -equalsIgnoreCase, -reverse, -hashCode, -indexOf, -isAlnum, -isAlpha, -isAscii, -isDigit, -isEmpty, -isHexDigit, -isLowerCase, -isSpace, -isPrintable, -isUpperCase, -isVisible, -lastIndexOf, -length, -matches, -replaceAll, -replaceFirst, -startsWith, -substring, -swapCase, -toLowerCase, -toString, -toUpperCase, -trim, and -zfill.

Look at the contains example:

[Desktop]$ String a testXccc
[Desktop]$ a.contains tX
true
[Desktop]$ a.contains XtX
false

oobash is available at Sourceforge.net.

Actually, it is very simple. If you want a simple black rectangle behind the Textview, just add android:background="@android:color/black" within the TextView tags. Like this:

<TextView
    android:textSize="15pt" android:textColor="#ffa7ff04"
    android:layout_alignBottom="@+id/webView1"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true"
    android:background="@android:color/black"/>

I got the same error when I had Authentication disabled/chose "No Authentication'. I re-made my project and chose "Individual User Accounts" and I didn't get the error anymore.

The translation is correct, the typing of the expression isn't. TypeScript is incorrectly typing the expression new Thing[100] as an array. It should be an error to index Thing, a constructor function, using the index operator. In C# this would allocate an array of 100 elements. In JavaScript this calls the value at index 100 of Thing as if was a constructor. Since that values is undefined it raises the error you mentioned. In JavaScript and TypeScript you want new Array(100) instead.

You should report this as a bug on CodePlex.

LENGTH() returns the length of the string measured in bytes.
CHAR_LENGTH() returns the length of the string measured in characters.

This is especially relevant for Unicode, in which most characters are encoded in two bytes. Or UTF-8, where the number of bytes varies. For example:

select length(_utf8 '€'), char_length(_utf8 '€')
--> 3, 1

As you can see the Euro sign occupies 3 bytes (it's encoded as 0xE282AC in UTF-8) even though it's only one character.

If you need to retrieve a URL query from outside a component:

import router from 'next/router'

console.log(router.query)

This change only first handle in multihandle slider. In apiDoc you can see:"For example, if you specify values: [ 1, 5, 18 ] and create one custom handle, the plugin will create the other two."

Update 27 Feb 2015: My original answer keeps getting voted up, but now I normally use @bobince's approach instead.

.child { /* This is the item to center... */
  display: inline-block;
}
.parent { /* ...and this is its parent container. */
  text-align: center;
}

My original post for historical purposes:

You might want to try this approach.

<div class="product_container">
    <div class="outer-center">
        <div class="product inner-center">
        </div>
    </div>
    <div class="clear"/>
</div>

Here's the matching style:

.outer-center {
    float: right;
    right: 50%;
    position: relative;
}
.inner-center {
    float: right;
    right: -50%;
    position: relative;
}
.clear {
    clear: both;
}

JSFiddle

The idea here is that you contain the content you want to center in two divs, an outer one and an inner one. You float both divs so that their widths automatically shrink to fit your content. Next, you relatively position the outer div with it's right edge in the center of the container. Lastly, you relatively position the inner div the opposite direction by half of its own width (actually the outer div's width, but they are the same). Ultimately that centers the content in whatever container it's in.

You may need that empty div at the end if you depend on your "product" content to size the height for the "product_container".

This will do what you want:

<?php

$array = array(2 => 'a', 1 => 'b', 0 => 'c');

array_unshift($array, false); // Add to the start of the array
$array = array_values($array); // Re-number

// Remove the first index so we start at 1
$array = array_slice($array, 1, count($array), true);

print_r($array); // Array ( [1] => a [2] => b [3] => c ) 

?>
