ORA-12899: value too large for column "DJ"."CUSTOMERS"."ADDRESS" (actual: 25, maximum: 2

Tells you what the error is. Address can hold maximum of 20 characters, you are passing 25 characters.

You can proceed in this way. It must work for you as well!

Step 1:

virtualenv venv 
source venv/bin/activate

Step 2:

sudo python3 -m pip install opencv-python==3.4.2.16 
sudo python3 -m pip install opencv-contrib-python==3.4.2.16

Step 3:

import cv2
sift = cv2.xfeatures2d.SIFT_create()

Don't use cv2.SIFT() . It will raise an exception.

Try this once and make sure you are not getting any error in project Structure saying that "ComGoogleAndroidGmsPlay not added"

Open File > Project Structure and check for below all. If error is shown click on Red bulb marked and click on "Add to dependency".

This is a bug in Android Studio and fixed for the next release(0.4.3)

In my case I had to wrap the bootstrapping of my second app in angular.element(document).ready for it to work:

angular.element(document).ready(function() {
  angular.bootstrap(document.getElementById("app2"), ["app2"]);
});   

There's most likely a more elegant way, but this does find every record with a letter in it, both upper or lower case:

select * from your_table
where UPPER(your_field) like '%A%'
or UPPER(your_field) like '%B%'
or UPPER(your_field) like '%C%'
or UPPER(your_field) like '%D%'
or UPPER(your_field) like '%E%'
or UPPER(your_field) like '%F%'
or UPPER(your_field) like '%G%'
or UPPER(your_field) like '%H%'
or UPPER(your_field) like '%I%'
or UPPER(your_field) like '%J%'
or UPPER(your_field) like '%K%'
or UPPER(your_field) like '%L%'
or UPPER(your_field) like '%M%'
or UPPER(your_field) like '%N%'
or UPPER(your_field) like '%O%'
or UPPER(your_field) like '%P%'
or UPPER(your_field) like '%Q%'
or UPPER(your_field) like '%R%'
or UPPER(your_field) like '%S%'
or UPPER(your_field) like '%T%'
or UPPER(your_field) like '%U%'
or UPPER(your_field) like '%V%'
or UPPER(your_field) like '%W%'
or UPPER(your_field) like '%X%'
or UPPER(your_field) like '%Y%'
or UPPER(your_field) like '%Z%'

For MS SQL you can do this.

    select  CAST(DATEPART(MONTH, DateTyme) as VARCHAR) +'/'+ 
CAST(DATEPART(YEAR, DateTyme) as VARCHAR) as 'Date' from #temp
    group by Name, CAST(DATEPART(MONTH, DateTyme) as VARCHAR) +'/'+
 CAST(DATEPART(YEAR, DateTyme) as VARCHAR) 

in your main layout put this in the head at the bottom of everything

@stack('styles')

and in your view put this

@push('styles')

    <link rel="stylesheet" href="{{ asset('css/app.css') }}">

@endpush

basically a placeholder so the links will appear on your main layout, and you can see custom css files on different pages

-- TRY THIS --

select name= case when isnumeric(empname)= 1 then 'numeric' else 'notmumeric' end from [Employees]

But conversion is quit impossible

select empname=
case
when isnumeric(empname)= 1 then empname
else 'notmumeric'
end
from [Employees]

In this context, "attribute" simply means a data member of an object.

It amazing for me, for solving Field 'id' doesn't have a default value? I have tried all the possible ways what are given here like..

set sql_mode=""
set @@sql_mode = ''; etc

but unfortunately these didn't work for me. So after long investigation, I found that

@Entity
@Table(name="vendor_table")
public class Customer {
    @Id
    @Column(name="cid")
    private int cid;
.....
}

@Entity
@Table(name="vendor_table")
public class Vendor {
    @Id
    private int vid;
    @Column
    private String vname;
    .....
}

here you can see that both tables are having same name. It is very funny mistake, was done by me :)))). After correcting this,my problem was gone off.

There is an option to create virtual environments in Anaconda with required Python version.

conda create -n myenv python=3.4

To activate it :

source activate myenv   # (in linux, you can use . as a shortcut for "source")
activate myenv          # (in windows - note that you should be in your c:\anaconda2 directory)

UPDATE. I have tested it with Ubuntu 18.04. Now you have to install spyder additionally for the new environment with this command (after the activation of the environment with the command above):

conda install spyder

(I have also tested the installation with pip, but for Python 3.4 or older versions, it breaks with the library dependencies error that requires manual installation.)

And now to run Spyder with Python 3.4 just type:

spyder

EDIT from a reader:

For a normal opening, use "Anaconda Prompt" > activate myenv > spyder (then the "Anaconda Prompt" must stay open, you cannot use it for other commands, and a force-close will shut down Spyder). This is of course faster than the long load of "Anaconda Navigator" > switch environment > launch Spyder (@adelriosantiago's answer).

If you're allergic to string concatenation and don't need IE compatibility, you can use URL and URLSearchParams:

const target = new URL('https://example.com/endpoint');_x000D_
const params = new URLSearchParams();_x000D_
params.set('var1', 'foo');_x000D_
params.set('var2', 'bar');_x000D_
target.search = params.toString();_x000D_
_x000D_
console.log(target);

Or to convert an entire object's worth of parameters:

const paramsObject = {_x000D_
  var1: 'foo',_x000D_
  var2: 'bar'_x000D_
};_x000D_
_x000D_
const target = new URL('https://example.com/endpoint');_x000D_
target.search = new URLSearchParams(paramsObject).toString();_x000D_
_x000D_
console.log(target);

An update. Dates of the form '2019-08-00' will trigger the same error. Adding the lines:

[mysqld]

sql_mode="NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION" 

to mysql.cnf fixes this too. Inserting malformed dates now generates warnings for values out of range but does insert the data.

You need to add the following lines in your catalina.sh file.

export CATALINA_OPTS="-Xms512M -Xmx1024M"

UPDATE : catalina.sh content clearly says -

Do not set the variables in this script. Instead put them into a script setenv.sh in CATALINA_BASE/bin to keep your customizations separate.

So you can add above in setenv.sh instead (create a file if it does not exist).

I was able to setup Oracle Instant Client (Basic) 11g2 and Oracle ODBC (32bit) drivers on my 32bit Windows 7 PC. Note: you'll need a 'tnsnames.ora' file because it doesn't come with one. You can Google examples and copy/paste into a text file, change the parameters for your environment.

Setting up Oracle Instant Client-Basic 11g2 (Win7 32-bit)
(I think there's another step or two if your using 64-bit)

Oracle Instant Client

• Unzip Oracle Instant Client - Basic
• Put contents in folder like "C:\instantclient"
• Edit PATH evironment variable, add path to Instant Client folder to the Variable Value.
• Add new Variable called "TNS_ADMIN" point to same folder as Instant Client.
• I had to create a "tnsnames.ora" file because it doesn't come with one. Put it in same folder as the client.
• reboot or use Task Manager to kill "explorer.exe" and restart it to refresh the PATH environment variables.

ODBC Drivers

• Unzip ODBC drivers
• Copy all files into same folder as client "C:\instantclient"
• Use command prompt to run "odbc_install.exe" (should say it was successful)

Note: The "un-documented" things that were hanging me up where...
- All files (Client and Drivers) needed to be in the same folder (nothing in sub-folders).
- Running the ODBC driver from the command prompt will allow you to see if it installs successfully. Double-clicking the installer just flashed a box on the screen, no idea it was failing because no error dialog.

After you've done this you should be able to setup a new DSN Data Source using the Oracle ODBC driver.
-Hope this helps someone else.

Yes! exit(). It's in <cstdlib>.

If you want to get the key name of myVar object then you can use Object.keys() for this purpose.

var result = Object.keys(myVar); 

alert(result[0]) // result[0] alerts typeA

MySQL added this utf8mb4 code after 5.5.3, Mb4 is the most bytes 4 meaning, specifically designed to be compatible with four-byte Unicode. Fortunately, UTF8MB4 is a superset of UTF8, except that there is no need to convert the encoding to UTF8MB4. Of course, in order to save space, the general use of UTF8 is enough.

The original UTF-8 format uses one to six bytes and can encode 31 characters maximum. The latest UTF-8 specification uses only one to four bytes and can encode up to 21 bits, just to represent all 17 Unicode planes. UTF8 is a character set in Mysql that supports only a maximum of three bytes of UTF-8 characters, which is the basic multi-text plane in Unicode.

To save 4-byte-long UTF-8 characters in Mysql, you need to use the UTF8MB4 character set, but only 5.5. After 3 versions are supported (View version: Select version ();). I think that in order to get better compatibility, you should always use UTF8MB4 instead of UTF8. For char type data, UTF8MB4 consumes more space and, according to Mysql's official recommendation, uses VARCHAR instead of char.

In MariaDB utf8mb4 as the default CHARSET when it not set explicitly in the server config, hence COLLATE utf8mb4_unicode_ci is used.

Refer MariaDB CHARSET & COLLATE Click

CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

InnoDB has transaction support, you're not using explicit transactions so innoDB has to do a commit after each statement ("performs a log flush to disk for every insert").

Execute this command before your loop:

START TRANSACTION

and this after you loop

COMMIT

On some servers and web hosts, it's possible to disable ModSecurity via .htaccess, but be aware that you can only switch it on or off, you can't disable individual rules.

But a good practice that still keeps your site secure is to disable it only on specific URLs, rather than your entire site. You can specify which URLs to match via the regex in the <If> statement below...

### DISABLE mod_security firewall
### Some rules are currently too strict and are blocking legitimate users
### We only disable it for URLs that contain the regex below
### The regex below should be placed between "m#" and "#" 
### (this syntax is required when the string contains forward slashes)
<IfModule mod_security.c>
  <If "%{REQUEST_URI} =~ m#/admin/#">
    SecFilterEngine Off
    SecFilterScanPOST Off
  </If>
</IfModule>

To add to Reed Copsey's answer about using Task.FromResult, you can improve performance even more if you cache the already completed task since all instances of completed tasks are the same:

public static class TaskExtensions
{
    public static readonly Task CompletedTask = Task.FromResult(false);
}

With TaskExtensions.CompletedTask you can use the same instance throughout the entire app domain.

The latest version of the .Net Framework (v4.6) adds just that with the Task.CompletedTask static property

Task completedTask = Task.CompletedTask;

Ok i finally managed to do it without using the --privileged mode.

I'm running on ubuntu server 14.04 and i'm using the latest cuda (6.0.37 for linux 13.04 64 bits).

Preparation

Install nvidia driver and cuda on your host. (it can be a little tricky so i will suggest you follow this guide https://askubuntu.com/questions/451672/installing-and-testing-cuda-in-ubuntu-14-04)

ATTENTION : It's really important that you keep the files you used for the host cuda installation

Get the Docker Daemon to run using lxc

We need to run docker daemon using lxc driver to be able to modify the configuration and give the container access to the device.

One time utilization :

sudo service docker stop
sudo docker -d -e lxc

Permanent configuration Modify your docker configuration file located in /etc/default/docker Change the line DOCKER_OPTS by adding '-e lxc' Here is my line after modification

DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4 -e lxc"

Then restart the daemon using

sudo service docker restart

How to check if the daemon effectively use lxc driver ?

docker info

The Execution Driver line should look like that :

Execution Driver: lxc-1.0.5

Build your image with the NVIDIA and CUDA driver.

Here is a basic Dockerfile to build a CUDA compatible image.

Run your image.

First you need to identify your the major number associated with your device. Easiest way is to do the following command :

ls -la /dev | grep nvidia

If the result is blank, use launching one of the samples on the host should do the trick. The result should look like that As you can see there is a set of 2 numbers between the group and the date. These 2 numbers are called major and minor numbers (wrote in that order) and design a device. We will just use the major numbers for convenience.

Why do we activated lxc driver? To use the lxc conf option that allow us to permit our container to access those devices. The option is : (i recommend using * for the minor number cause it reduce the length of the run command)

--lxc-conf='lxc.cgroup.devices.allow = c [major number]:[minor number or *] rwm'

So if i want to launch a container (Supposing your image name is cuda).

docker run -ti --lxc-conf='lxc.cgroup.devices.allow = c 195:* rwm' --lxc-conf='lxc.cgroup.devices.allow = c 243:* rwm' cuda

I also got this error .I was using Text inside body after changing to XML(text/xml) , got result as expected.

• If your request is XML Request use XML(text/xml).

• If your request is JSON Request use JSON(application/json)

If your signatures differ only in the number of arguments, using default arguments is the right way to do it. If you want to be able to pass in different kinds of argument, I would try to avoid the isinstance-based approach mentioned in another answer, and instead use keyword arguments.

If using just keyword arguments becomes unwieldy, you can combine it with classmethods (the bzrlib code likes this approach). This is just a silly example, but I hope you get the idea:

class C(object):

    def __init__(self, fd):
        # Assume fd is a file-like object.
        self.fd = fd

    @classmethod
    def fromfilename(cls, name):
        return cls(open(name, 'rb'))

# Now you can do:
c = C(fd)
# or:
c = C.fromfilename('a filename')

Notice all those classmethods still go through the same __init__, but using classmethods can be much more convenient than having to remember what combinations of keyword arguments to __init__ work.

isinstance is best avoided because Python's duck typing makes it hard to figure out what kind of object was actually passed in. For example: if you want to take either a filename or a file-like object you cannot use isinstance(arg, file), because there are many file-like objects that do not subclass file (like the ones returned from urllib, or StringIO, or...). It's usually a better idea to just have the caller tell you explicitly what kind of object was meant, by using different keyword arguments.

I've compared the different options for speed and found that – much to my surprise – all options (except diag) are equally fast. I personally use

A * b[:, None]

(or (A.T * b).T) because it's short.

Code to reproduce the plot:

import numpy
import perfplot


def newaxis(data):
    A, b = data
    return A * b[:, numpy.newaxis]


def none(data):
    A, b = data
    return A * b[:, None]


def double_transpose(data):
    A, b = data
    return (A.T * b).T


def double_transpose_contiguous(data):
    A, b = data
    return numpy.ascontiguousarray((A.T * b).T)


def diag_dot(data):
    A, b = data
    return numpy.dot(numpy.diag(b), A)


def einsum(data):
    A, b = data
    return numpy.einsum("ij,i->ij", A, b)


perfplot.save(
    "p.png",
    setup=lambda n: (numpy.random.rand(n, n), numpy.random.rand(n)),
    kernels=[
        newaxis,
        none,
        double_transpose,
        double_transpose_contiguous,
        diag_dot,
        einsum,
    ],
    n_range=[2 ** k for k in range(13)],
    xlabel="len(A), len(b)",
)

Bootstrap 4 Beta Answer:

d-block d-md-none to hide on medium, large and extra large devices.

d-none d-md-block to hide on small and extra-small devices.

Note that you can also inline by replacing d-*-block with d-*-inline-block

Old answer: Bootstrap 4 Alpha

• You can use the classes .hidden-*-up to hide on a given size and larger devices

  .hidden-md-up to hide on medium, large and extra large devices.

• The same goes with .hidden-*-down to hide on a given size and smaller devices

  .hidden-md-down to hide on medium, small and extra-small devices

• visible-* is no longer an option with bootstrap 4

• To display only on medium devices, you can combine the two:

  hidden-sm-down and hidden-xl-up

The valid sizes are:

• xs for phones in portrait mode (<34em)
• sm for phones in landscape mode (=34em)
• md for tablets (=48em)
• lg for desktops (=62em)
• xl for desktops (=75em)

This was as of Bootstrap 4, alpha 5 (January 2017). More details here: http://v4-alpha.getbootstrap.com/layout/responsive-utilities/

On Bootstrap 4.3.x: https://getbootstrap.com/docs/4.3/utilities/display/

Its better to always encode spaces as %20, not as "+".

It was RFC-1866 (HTML 2.0 specification), which specified that space characters should be encoded as "+" in "application/x-www-form-urlencoded" content-type key-value pairs. (see paragraph 8.2.1. subparagraph 1.). This way of encoding form data is also given in later HTML specifications, look for relevant paragraphs about application/x-www-form-urlencoded.

Here is an example of such a string in URL where RFC-1866 allows encoding spaces as pluses: "http://example.com/over/there?name=foo+bar". So, only after "?", spaces can be replaced by pluses, according to RFC-1866. In other cases, spaces should be encoded to %20. But since it's hard to determine the context, it's the best practice to never encode spaces as "+".

I would recommend to percent-encode all character except "unreserved" defined in RFC-3986, p.2.3

unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"

NOTE: Before trying this code, please find this line in the below code:

private static String DB_NAME ="YourDbName"; // Database name

DB_NAME here is the name of your database. It is assumed that you have a copy of the database in the assets folder, so for example, if your database name is ordersDB, then the value of DB_NAME will be ordersDB,

private static String DB_NAME ="ordersDB";

Keep the database in assets folder and then follow the below:

                copyDataBase();
                Log.e(TAG, "createDatabase database created");
            } catch (IOException mIOException) {
                throw new Error("ErrorCopyingDataBase");
            }
        }
    }

    // Check that the database file exists in databases folder
    private boolean checkDataBase() {
        return DB_FILE.exists();
    }

    // Copy the database from assets
    private void copyDataBase() throws IOException {
        InputStream mInput = mContext.getAssets().open(DB_NAME);
        OutputStream mOutput = new FileOutputStream(DB_FILE);
        byte[] mBuffer = new byte[1024];
        int mLength;
        while ((mLength = mInput.read(mBuffer)) > 0) {
            mOutput.write(mBuffer, 0, mLength);
        }
        mOutput.flush();
        mOutput.close();
        mInput.close();
    }

    // Open the database, so we can query it
    public boolean openDataBase() throws SQLException {
        // Log.v("DB_PATH", DB_FILE.getAbsolutePath());
        mDataBase = SQLiteDatabase.openDatabase(DB_FILE, null, SQLiteDatabase.CREATE_IF_NECESSARY);
        // mDataBase = SQLiteDatabase.openDatabase(DB_FILE, null, SQLiteDatabase.NO_LOCALIZED_COLLATORS);
        return mDataBase != null;
    }

    @Override
    public synchronized void close() {
        if(mDataBase != null) {
            mDataBase.close();
        }
        super.close();
    }

}

Write a DataAdapter class like:

import java.io.IOException;
import android.content.Context;
import android.database.Cursor;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.util.Log;

public class TestAdapter {

    protected static final String TAG = "DataAdapter";

    private final Context mContext;
    private SQLiteDatabase mDb;
    private DataBaseHelper mDbHelper;

    public TestAdapter(Context context) {
        this.mContext = context;
        mDbHelper = new DataBaseHelper(mContext);
    }

    public TestAdapter createDatabase() throws SQLException {
        try {
            mDbHelper.createDataBase();
        } catch (IOException mIOException) {
            Log.e(TAG, mIOException.toString() + "  UnableToCreateDatabase");
            throw new Error("UnableToCreateDatabase");
        }
        return this;
    }

    public TestAdapter open() throws SQLException {
        try {
            mDbHelper.openDataBase();
            mDbHelper.close();
            mDb = mDbHelper.getReadableDatabase();
        } catch (SQLException mSQLException) {
            Log.e(TAG, "open >>"+ mSQLException.toString());
            throw mSQLException;
        }
        return this;
    }

    public void close() {
        mDbHelper.close();
    }

     public Cursor getTestData() {
         try {
             String sql ="SELECT * FROM myTable";
             Cursor mCur = mDb.rawQuery(sql, null);
             if (mCur != null) {
                mCur.moveToNext();
             }
             return mCur;
         } catch (SQLException mSQLException) {
             Log.e(TAG, "getTestData >>"+ mSQLException.toString());
             throw mSQLException;
         }
     }
}

Now you can use it like:

TestAdapter mDbHelper = new TestAdapter(urContext);
mDbHelper.createDatabase();
mDbHelper.open();

Cursor testdata = mDbHelper.getTestData();

mDbHelper.close();

For Android 4.1 (Jelly Bean), change:

DB_PATH = "/data/data/" + context.getPackageName() + "/databases/";

to:

DB_PATH = context.getApplicationInfo().dataDir + "/databases/";

in the DataHelper class, this code will work on Jelly Bean 4.2 multi-users.

EDIT: Instead of using hardcoded path, we can use

DB_PATH = context.getDatabasePath(DB_NAME).getAbsolutePath();

which will give us the full path to the database file and works on all Android versions

Enhancing one of the above solutions. As adding 1 day to end date sometimes adds an extra day beyond the end date.

    public static List getDaysBetweenDates(Date startdate, Date enddate)
    {
        List dates = new ArrayList();
        Calendar startDay = new GregorianCalendar();
        calendar.setTime(startdate);
        Calendar endDay = new GregorianCalendar();
        endDay.setTime(enddate);
        endDay.add(Calendar.DAY_OF_YEAR, 1);
        endDay.set(Calendar.HOUR_OF_DAY, 0);
        endDay.set(Calendar.MINUTE, 0);
        endDay.set(Calendar.SECOND, 0);
        endDay.set(Calendar.MILLISECOND, 0);

        while (calendar.getTime().before(endDay.getTime())) {
            Date result = startDay.getTime();
            dates.add(result);
            startDay.add(Calendar.DATE, 1);
        }
        return dates;
    }

@m59 Directives will work for ng-bind-html you just need to wait for $viewContentLoaded to finish

app.directive('targetBlank', function($timeout) {
  return function($scope, element) {
    $scope.initializeTarget = function() {
      return $scope.$on('$viewContentLoaded', $timeout(function() {
        var elems;
        elems = element.prop('tagName') === 'A' ? element : element.find('a');
        elems.attr('target', '_blank');
      }));
    };
    return $scope.initializeTarget();

  };
});

Change the code to

List<string> nameslist = new List<string> {"one", "two", "three"};

or

List<string> nameslist = new List<string>(new[] {"one", "two", "three"});

They are two formats of representation of information. While JSON was designed to be more compact, XML was design to be more readable.

If you don't mind a paid-for product, PowerGREP is my personal favorite.

  $objPHPExcel->getActiveSheet()->getStyle('B3:B7')->getFill()
->setFillType(PHPExcel_Style_Fill::FILL_SOLID)
->getStartColor()->setARGB('FFFF0000');

For linux versions(ubuntu/linux mint), you can always type this in the command prompt:

sudo apt-get install python-setuptools

this will automatically install eas-_install

As an alternate streaming approach:

• dump each col into a file
• use python or unix paste command to rejoin on tab, csv, whatever.

Both steps should handle steaming just fine.

Pitfalls:

• if you have 1000s of columns, you might run into the unix file handle limit!

You could just do this:

Activity:

Fragment someFragment;    

//...onCreate etc instantiating your fragments

public void myClickMethod(View v) {
    someFragment.myClickMethod(v);
}

Fragment:

public void myClickMethod(View v) {
    switch(v.getId()) {
        // Just like you were doing
    }
}    

In response to @Ameen who wanted less coupling so Fragments are reuseable

Interface:

public interface XmlClickable {
    void myClickMethod(View v);
}

Activity:

XmlClickable someFragment;    

//...onCreate, etc. instantiating your fragments casting to your interface.

public void myClickMethod(View v) {
    someFragment.myClickMethod(v);
}

Fragment:

public class SomeFragment implements XmlClickable {

//...onCreateView, etc.

@Override
public void myClickMethod(View v) {
    switch(v.getId()){
        // Just like you were doing
    }
}    

you can send your DateTime value into SQL as a String with its special format. this format is "yyyy-MM-dd HH:mm:ss"

Example: CurrentTime is a variable as datetime Type in SQL. And dt is a DateTime variable in .Net.

DateTime dt=DateTime.Now;
string sql = "insert into Users (CurrentTime) values (‘{0}’)";

sql = string.Format(sql, dt.ToString("yyyy-MM-dd HH:mm:ss") );

With redis-cli:

FLUSHDB       - Removes data from your connection's CURRENT database.
FLUSHALL      - Removes data from ALL databases.

Download whatever configuration script that your browser is using.

the script would have various host:port configuration. based on the domain you want to connect , one of the host:port is selected by the borwser.

in the eclipse network setting you can try to put on of the host ports and see if that works.

worked for me.

the config script looks like,

if (isPlainHostName(host))
    return "DIRECT";
else if (dnsDomainIs(host, "<***sample host name *******>"))
    return "PROXY ***some ip*****; DIRECT";
else if (dnsDomainIs(host, "address.com")
        || dnsDomainIs(host, "adress2..com")
        || dnsDomainIs(host, "address3.com")
        || dnsDomainIs(host, "address4.com")        
    return "PROXY <***some proxyhost****>:8080";

you would need to look for the host port in the return statement.

VBA stands for Visual Basic for Applications and so is the small "for applications" scripting brother of VB. VBA is indeed available in Excel, but also in the other office applications.

With VB, one can create a stand-alone windows application, which is not possible with VBA.

It is possible for developers however to "embed" VBA in their own applications, as a scripting language to automate those applications.

Edit: From the VBA FAQ:

Q. What is Visual Basic for Applications?

A. Microsoft Visual Basic for Applications (VBA) is an embeddable programming environment designed to enable developers to build custom solutions using the full power of Microsoft Visual Basic. Developers using applications that host VBA can automate and extend the application functionality, shortening the development cycle of custom business solutions.

Note that VB.NET is even another language, which only shares syntax with VB.

eloone did it file by file with

git checkout <commit-hash> <filename>

but you could checkout all files more easily by doing

git checkout <commit-hash> .

In my case, I used a callback in yaxis ticks, my values are in percent and when it reaches 100% it doesn't show the dot, I used this :

      yAxes: [{
                   ticks: {
                       beginAtZero: true,
                       steps: 10,
                       stepValue: 5,
                       min: 0,
                       max: 100.1,
                       callback: function(value, index, values) {
                           if (value !== 100.1) {
                               return values[index]
                           }
                       }
                   }
               }],

And it worked well.

Dir.foreach("/home/mydir") do |fname|
  puts fname
end

go to the url about:config and paste each line:

network.http.connection-retry-timeout;10
network.http.pipelining.read-timeout;5
network.http.connection-timeout;10

If you're trying to do stuff with the Java default system keystore (cacerts), then the default password is changeit.

You can list keys without needing the password (even if it prompts you) so don't take that as an indication that it is blank.

(Incidentally who in the history of Java ever has changed the default keystore password? They should have left it blank.)

Following code works..

datePickerButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showDialog(0);
        }
    });

@Override
@Deprecated
protected Dialog onCreateDialog(int id) {
    return new DatePickerDialog(this, datePickerListener, year, month, day);
}

private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
    public void onDateSet(DatePicker view, int selectedYear,
                          int selectedMonth, int selectedDay) {
        day = selectedDay;
        month = selectedMonth;
        year = selectedYear;
        datePickerButton.setText(selectedDay + " / " + (selectedMonth + 1) + " / "
                + selectedYear);
    }
};

C++20 will add constexpr strings and vectors

The following proposal has been accepted apparently: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0980r0.pdf and it adds constructors such as:

// 20.3.2.2, construct/copy/destroy
constexpr
basic_string() noexcept(noexcept(Allocator())) : basic_string(Allocator()) { }
constexpr
explicit basic_string(const Allocator& a) noexcept;
constexpr
basic_string(const basic_string& str);
constexpr
basic_string(basic_string&& str) noexcept;

in addition to constexpr versions of all / most methods.

There is no support as of GCC 9.1.0, the following fails to compile:

#include <string>

int main() {
    constexpr std::string s("abc");
}

with:

g++-9 -std=c++2a main.cpp

with error:

error: the type ‘const string’ {aka ‘const std::__cxx11::basic_string<char>’} of ‘constexpr’ variable ‘s’ is not literal

std::vector discussed at: Cannot create constexpr std::vector

Tested in Ubuntu 19.04.

<h4>Order List</h4>
<ul>

Its workaround.

If you not push to server, you will clone into new folder else washout(delete all files) from your repository folder and clone new.

You can do this from the twig template:

{{ form_widget(form.birthdate, { 'attr': {'class': 'calendar'} }) }}

I use the ArrayDebugView add-in for Visual Studio (http://arraydebugview.sourceforge.net/).

It seems to be a long dead project (but one I'm looking at continuing myself) but the add-in still works beautifully for me in VS2010 for both C++ and C#.

It has a few quirks (tab order, modal dialog, no close button) but the ability to plot the contents of an array in a graph more than make up for it.

Edit July 2014: I have finally built a new Visual Studio extension to replace ArrayebugView's functionality. It is available on the VIsual Studio Gallery, search for ArrayPlotter or go to http://visualstudiogallery.msdn.microsoft.com/2fde2c3c-5b83-4d2a-a71e-5fdd83ce6b96?SRC=Home

Yes it's possible. Look!

$str = str_replace('\\', '', $str);

But why would you want to?

use html link instead of asp link and you can use label in between html link for server side control

Always, for any issue regarding the JavaScript spec in practical, I will highly recommend the Mozilla Developer Network, and their JavaScript reference.

As it states in the topic of the Date object about the argument variant you use:

new Date(year, month, day [, hour, minute, second, millisecond ])

And about the months parameter:

month Integer value representing the month, beginning with 0 for January to 11 for December.

Clearly, then, you should use the month number 10 for November.

P.S.: The reason why I recommend the MDN is the correctness, good explanation of things, examples, and browser compatibility chart.

cd C:\path\dir
svn checkout https://server/path/to/trunk/dir/dir/parent_dir--depth empty
cd C:\path\dir\parent_dir
svn update filename.log

(Edit filename.log)

svn commit -m "this is a comment."

Use basic programming composition: create a method and pass the same function to click and hover as a callback.

var hoverOrClick = function () {
    // do something common
}
$('#target').click(hoverOrClick).hover(hoverOrClick);

Second way: use bindon:

$('#target').on('click mouseover', function () {
    // Do something for both
});

jQuery('#target').bind('click mouseover', function () {
    // Do something for both
});

One way would be to create all commits ever made to patches. checkout the initial commit and then apply the patches in order after reading.

use git format-patch <initial revision> and then git checkout <initial revision>. you should get a pile of files in your director starting with four digits which are the patches.

when you are done reading your revision just do git apply <filename> which should look like git apply 0001-* and count.

But I really wonder why you wouldn't just want to read the patches itself instead? Please post this in your comments because I'm curious.

the git manual also gives me this:

git show next~10:Documentation/README

Shows the contents of the file Documentation/README as they were current in the 10th last commit of the branch next.

you could also have a look at git blame filename which gives you a listing where each line is associated with a commit hash + author.

If you're trying to copy the array:

array2 = array[:]

How can I send my $scope object from one controller to another using .$emit and .$on methods?

You can send any object you want within the hierarchy of your app, including $scope.

Here is a quick idea about how broadcast and emit work.

Notice the nodes below; all nested within node 3. You use broadcast and emit when you have this scenario.

Note: The number of each node in this example is arbitrary; it could easily be the number one; the number two; or even the number 1,348. Each number is just an identifier for this example. The point of this example is to show nesting of Angular controllers/directives.

                 3
           ------------
           |          |
         -----     ------
         1   |     2    |
      ---   ---   ---  ---
      | |   | |   | |  | |

Check out this tree. How do you answer the following questions?

Note: There are other ways to answer these questions, but here we'll discuss broadcast and emit. Also, when reading below text assume each number has it's own file (directive, controller) e.x. one.js, two.js, three.js.

How does node 1 speak to node 3?

In file one.js

scope.$emit('messageOne', someValue(s));

In file three.js - the uppermost node to all children nodes needed to communicate.

scope.$on('messageOne', someValue(s));

How does node 2 speak to node 3?

In file two.js

scope.$emit('messageTwo', someValue(s));

In file three.js - the uppermost node to all children nodes needed to communicate.

scope.$on('messageTwo', someValue(s));

How does node 3 speak to node 1 and/or node 2?

In file three.js - the uppermost node to all children nodes needed to communicate.

scope.$broadcast('messageThree', someValue(s));

In file one.js && two.js whichever file you want to catch the message or both.

scope.$on('messageThree', someValue(s));

How does node 2 speak to node 1?

In file two.js

scope.$emit('messageTwo', someValue(s));

In file three.js - the uppermost node to all children nodes needed to communicate.

scope.$on('messageTwo', function( event, data ){
  scope.$broadcast( 'messageTwo', data );
});

In file one.js

scope.$on('messageTwo', someValue(s));

HOWEVER

When you have all these nested child nodes trying to communicate like this, you will quickly see many $on's, $broadcast's, and $emit's.

Here is what I like to do.

In the uppermost PARENT NODE ( 3 in this case... ), which may be your parent controller...

So, in file three.js

scope.$on('pushChangesToAllNodes', function( event, message ){
  scope.$broadcast( message.name, message.data );
});

Now in any of the child nodes you only need to $emit the message or catch it using $on.

NOTE: It is normally quite easy to cross talk in one nested path without using $emit, $broadcast, or $on, which means most use cases are for when you are trying to get node 1 to communicate with node 2 or vice versa.

How does node 2 speak to node 1?

In file two.js

scope.$emit('pushChangesToAllNodes', sendNewChanges());

function sendNewChanges(){ // for some event.
  return { name: 'talkToOne', data: [1,2,3] };
}

In file three.js - the uppermost node to all children nodes needed to communicate.

We already handled this one remember?

In file one.js

scope.$on('talkToOne', function( event, arrayOfNumbers ){
  arrayOfNumbers.forEach(function(number){
    console.log(number);
  });
});

You will still need to use $on with each specific value you want to catch, but now you can create whatever you like in any of the nodes without having to worry about how to get the message across the parent node gap as we catch and broadcast the generic pushChangesToAllNodes.

Hope this helps...

You need to Open the SQL Developer first and then click on File option and browse to the location where your .sql is placed. Once you are at the location where file is placed double click on it, this will get the file open in SQL Developer. Now select all of the content of file (CTRL + A) and press F9 key. Just make sure there is a commit statement at the end of the .sql script so that the changes are persisted in the database

To plot just a selection of your columns you can select the columns of interest by passing a list to the subscript operator:

ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)

What you tried was df['V1','V2'] this will raise a KeyError as correctly no column exists with that label, although it looks funny at first you have to consider that your are passing a list hence the double square brackets [[]].

import matplotlib.pyplot as plt
ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)
ax.set_xlabel("Hour", fontsize=12)
ax.set_ylabel("V", fontsize=12)
plt.show()

irb(main):005:0> {}.class
=> Hash
irb(main):006:0> [].class
=> Array

Basically, there are two ways to clear the cache:

<form autocomplete="off"></form>

or

$('#Textfiledid').attr('autocomplete', 'off');

The scrolling effect is cause by specifying the generic 'background' property in your css instead of the more specific background-image. By setting the background property, the animation will transition between all properties.. Background-Color, Background-Image, Background-Position.. Etc Thus causing the scrolling effect..

E.g.

a {
-webkit-transition-property: background-image 300ms ease-in 200ms;
-moz-transition-property: background-image 300ms ease-in 200ms;
-o-transition-property: background-image 300ms ease-in 200ms;
transition: background-image 300ms ease-in 200ms;
}

Assigning a value to a local variable and then returning that at the end is considered a good practice. Methods having multiple exits are harder to debug and can be difficult to read.

That said, thats the only plus point left to this paradigm. It was originated when only low-level procedural languages were around. And it made much more sense at that time.

While we are on the topic you must check this out. Its an interesting read.

Pandas is pretty good at dealing with data. Here is one example how to use it:

import pandas as pd

# Read the CSV into a pandas data frame (df)
#   With a df you can do many things
#   most important: visualize data with Seaborn
df = pd.read_csv('filename.csv', delimiter=',')

# Or export it in many ways, e.g. a list of tuples
tuples = [tuple(x) for x in df.values]

# or export it as a list of dicts
dicts = df.to_dict().values()

One big advantage is that pandas deals automatically with header rows.

If you haven't heard of Seaborn, I recommend having a look at it.

See also: How do I read and write CSV files with Python?

Pandas #2

import pandas as pd

# Get data - reading the CSV file
import mpu.pd
df = mpu.pd.example_df()

# Convert
dicts = df.to_dict('records')

The content of df is:

     country   population population_time    EUR
0    Germany   82521653.0      2016-12-01   True
1     France   66991000.0      2017-01-01   True
2  Indonesia  255461700.0      2017-01-01  False
3    Ireland    4761865.0             NaT   True
4      Spain   46549045.0      2017-06-01   True
5    Vatican          NaN             NaT   True

When executing adb commands, by default, a limited privileges user is used, the same kind of limited privilege user that is assigned to an app, and you have requested for all privelages to use all features of the device.

This kind of limited user helps protect your phone from malware, by restricting the access between apps, and the system. This is the reason you are unable to access app data and system data on an unrooted phone. The act of rooting means becoming user 0, the super user of the system, capable of any action, and is the highest privilege. Your apps however, are still secure in that they can not talk to eachother.

Now when accessing secure files, note that you do not want to change the permissions of the file when you access it, which may allow for vulnerabilities.

An option that you could use instead, is to make a copy of the file on the sdcard as root, modify that as a standard user, and then move it back into the filesystem as root, while preserving the file permissions of the original file.

I cannot comment on @Michael Blackburn, but I guess you got the downvote because the GroupBy is not necessary in this case.

Use it like:

var lookupOfCustomObjects = listOfCustomObjects.ToLookup(o=>o.PropertyName);
var listWithAllCustomObjectsWithPropertyName = lookupOfCustomObjects[propertyName]

Additionally, I've seen this perform way better than when using GroupBy().ToDictionary().

string.find("substring") will help you. This function returns -1 when there is no substring.

I was trying to solve the problem of being able to iterate over several different text arrays all of which are stored within a memory resident database that is a large struct.

The following was worked out using Visual Studio 2017 Community Edition on an MFC test application. I am including this as an example as this posting was one of several that I ran across that provided some help yet were still insufficient for my needs.

The struct containing the memory resident data looked something like the following. I have removed most of the elements for the sake of brevity and have also not included the Preprocessor defines used (the SDK in use is for C as well as C++ and is old).

What I was interested in doing is having iterators for the various WCHAR two dimensional arrays which contained text strings for mnemonics.

typedef struct  tagUNINTRAM {
    // stuff deleted ...
    WCHAR   ParaTransMnemo[MAX_TRANSM_NO][PARA_TRANSMNEMO_LEN]; /* prog #20 */
    WCHAR   ParaLeadThru[MAX_LEAD_NO][PARA_LEADTHRU_LEN];   /* prog #21 */
    WCHAR   ParaReportName[MAX_REPO_NO][PARA_REPORTNAME_LEN];   /* prog #22 */
    WCHAR   ParaSpeMnemo[MAX_SPEM_NO][PARA_SPEMNEMO_LEN];   /* prog #23 */
    WCHAR   ParaPCIF[MAX_PCIF_SIZE];            /* prog #39 */
    WCHAR   ParaAdjMnemo[MAX_ADJM_NO][PARA_ADJMNEMO_LEN];   /* prog #46 */
    WCHAR   ParaPrtModi[MAX_PRTMODI_NO][PARA_PRTMODI_LEN];  /* prog #47 */
    WCHAR   ParaMajorDEPT[MAX_MDEPT_NO][PARA_MAJORDEPT_LEN];    /* prog #48 */
    //  ... stuff deleted
} UNINIRAM;

The current approach is to use a template to define a proxy class for each of the arrays and then to have a single iterator class that can be used to iterate over a particular array by using a proxy object representing the array.

A copy of the memory resident data is stored in an object that handles reading and writing the memory resident data from/to disk. This class, CFilePara contains the templated proxy class (MnemonicIteratorDimSize and the sub class from which is it is derived, MnemonicIteratorDimSizeBase) and the iterator class, MnemonicIterator.

The created proxy object is attached to an iterator object which accesses the necessary information through an interface described by a base class from which all of the proxy classes are derived. The result is to have a single type of iterator class which can be used with several different proxy classes because the different proxy classes all expose the same interface, the interface of the proxy base class.

The first thing was to create a set of identifiers which would be provided to a class factory to generate the specific proxy object for that type of mnemonic. These identifiers are used as part of the user interface to identify the particular provisioning data the user is interested in seeing and possibly modifying.

const static DWORD_PTR dwId_TransactionMnemonic = 1;
const static DWORD_PTR dwId_ReportMnemonic = 2;
const static DWORD_PTR dwId_SpecialMnemonic = 3;
const static DWORD_PTR dwId_LeadThroughMnemonic = 4;

The Proxy Class

The templated proxy class and its base class are as follows. I needed to accommodate several different kinds of wchar_t text string arrays. The two dimensional arrays had different numbers of mnemonics, depending on the type (purpose) of the mnemonic and the different types of mnemonics were of different maximum lengths, varying between five text characters and twenty text characters. Templates for the derived proxy class was a natural fit with the template requiring the maximum number of characters in each mnemonic. After the proxy object is created, we then use the SetRange() method to specify the actual mnemonic array and its range.

// proxy object which represents a particular subsection of the
// memory resident database each of which is an array of wchar_t
// text arrays though the number of array elements may vary.
class MnemonicIteratorDimSizeBase
{
    DWORD_PTR  m_Type;

public:
    MnemonicIteratorDimSizeBase(DWORD_PTR x) { }
    virtual ~MnemonicIteratorDimSizeBase() { }

    virtual wchar_t *begin() = 0;
    virtual wchar_t *end() = 0;
    virtual wchar_t *get(int i) = 0;
    virtual int ItemSize() = 0;
    virtual int ItemCount() = 0;

    virtual DWORD_PTR ItemType() { return m_Type; }
};

template <size_t sDimSize>
class MnemonicIteratorDimSize : public MnemonicIteratorDimSizeBase
{
    wchar_t    (*m_begin)[sDimSize];
    wchar_t    (*m_end)[sDimSize];

public:
    MnemonicIteratorDimSize(DWORD_PTR x) : MnemonicIteratorDimSizeBase(x), m_begin(0), m_end(0) { }
    virtual ~MnemonicIteratorDimSize() { }

    virtual wchar_t *begin() { return m_begin[0]; }
    virtual wchar_t *end() { return m_end[0]; }
    virtual wchar_t *get(int i) { return m_begin[i]; }

    virtual int ItemSize() { return sDimSize; }
    virtual int ItemCount() { return m_end - m_begin; }

    void SetRange(wchar_t (*begin)[sDimSize], wchar_t (*end)[sDimSize]) {
        m_begin = begin; m_end = end;
    }

};

The Iterator Class

The iterator class itself is as follows. This class provides just basic forward iterator functionality which is all that is needed at this time. However I expect that this will change or be extended when I need something additional from it.

class MnemonicIterator
{
private:
    MnemonicIteratorDimSizeBase   *m_p;  // we do not own this pointer. we just use it to access current item.
    int      m_index;                    // zero based index of item.
    wchar_t  *m_item;                    // value to be returned.

public:
    MnemonicIterator(MnemonicIteratorDimSizeBase *p) : m_p(p) { }
    ~MnemonicIterator() { }

    // a ranged for needs begin() and end() to determine the range.
    // the range is up to but not including what end() returns.
    MnemonicIterator & begin() { m_item = m_p->get(m_index = 0); return *this; }                 // begining of range of values for ranged for. first item
    MnemonicIterator & end() { m_item = m_p->get(m_index = m_p->ItemCount()); return *this; }    // end of range of values for ranged for. item after last item.
    MnemonicIterator & operator ++ () { m_item = m_p->get(++m_index); return *this; }            // prefix increment, ++p
    MnemonicIterator & operator ++ (int i) { m_item = m_p->get(m_index++); return *this; }       // postfix increment, p++
    bool operator != (MnemonicIterator &p) { return **this != *p; }                              // minimum logical operator is not equal to
    wchar_t * operator *() const { return m_item; }                                              // dereference iterator to get what is pointed to
};

The proxy object factory determines which object to created based on the mnemonic identifier. The proxy object is created and the pointer returned is the standard base class type so as to have a uniform interface regardless of which of the different mnemonic sections are being accessed. The SetRange() method is used to specify to the proxy object the specific array elements the proxy represents and the range of the array elements.

CFilePara::MnemonicIteratorDimSizeBase * CFilePara::MakeIterator(DWORD_PTR x)
{
    CFilePara::MnemonicIteratorDimSizeBase  *mi = nullptr;

    switch (x) {
    case dwId_TransactionMnemonic:
        {
            CFilePara::MnemonicIteratorDimSize<PARA_TRANSMNEMO_LEN> *mk = new CFilePara::MnemonicIteratorDimSize<PARA_TRANSMNEMO_LEN>(x);
            mk->SetRange(&m_Para.ParaTransMnemo[0], &m_Para.ParaTransMnemo[MAX_TRANSM_NO]);
            mi = mk;
        }
        break;
    case dwId_ReportMnemonic:
        {
            CFilePara::MnemonicIteratorDimSize<PARA_REPORTNAME_LEN> *mk = new CFilePara::MnemonicIteratorDimSize<PARA_REPORTNAME_LEN>(x);
            mk->SetRange(&m_Para.ParaReportName[0], &m_Para.ParaReportName[MAX_REPO_NO]);
            mi = mk;
        }
        break;
    case dwId_SpecialMnemonic:
        {
            CFilePara::MnemonicIteratorDimSize<PARA_SPEMNEMO_LEN> *mk = new CFilePara::MnemonicIteratorDimSize<PARA_SPEMNEMO_LEN>(x);
            mk->SetRange(&m_Para.ParaSpeMnemo[0], &m_Para.ParaSpeMnemo[MAX_SPEM_NO]);
            mi = mk;
        }
        break;
    case dwId_LeadThroughMnemonic:
        {
            CFilePara::MnemonicIteratorDimSize<PARA_LEADTHRU_LEN> *mk = new CFilePara::MnemonicIteratorDimSize<PARA_LEADTHRU_LEN>(x);
            mk->SetRange(&m_Para.ParaLeadThru[0], &m_Para.ParaLeadThru[MAX_LEAD_NO]);
            mi = mk;
        }
        break;
    }

    return mi;
}

Using the Proxy Class and Iterator

The proxy class and its iterator are used as shown in the following loop to fill in a CListCtrl object with a list of mnemonics. I am using std::unique_ptr so that when the proxy class i not longer needed and the std::unique_ptr goes out of scope, the memory will be cleaned up.

What this source code does is to create a proxy object for the array within the struct which corresponds to the specified mnemonic identifier. It then creates an iterator for that object, uses a ranged for to fill in the CListCtrl control and then cleans up. These are all raw wchar_t text strings which may be exactly the number of array elements so we copy the string into a temporary buffer in order to ensure that the text is zero terminated.

    std::unique_ptr<CFilePara::MnemonicIteratorDimSizeBase> pObj(pFile->MakeIterator(m_IteratorType));
    CFilePara::MnemonicIterator pIter(pObj.get());  // provide the raw pointer to the iterator who doesn't own it.

    int i = 0;    // CListCtrl index for zero based position to insert mnemonic.
    for (auto x : pIter)
    {
        WCHAR szText[32] = { 0 };     // Temporary buffer.

        wcsncpy_s(szText, 32, x, pObj->ItemSize());
        m_mnemonicList.InsertItem(i, szText);  i++;
    }

String#matchAll (see the Stage 3 Draft / December 7, 2018 proposal), simplifies acccess to all groups in the match object (mind that Group 0 is the whole match, while further groups correspond to the capturing groups in the pattern):

With matchAll available, you can avoid the while loop and exec with /g... Instead, by using matchAll, you get back an iterator which you can use with the more convenient for...of, array spread, or Array.from() constructs

This method yields a similar output to Regex.Matches in C#, re.finditer in Python, preg_match_all in PHP.

See a JS demo (tested in Google Chrome 73.0.3683.67 (official build), beta (64-bit)):

var myString = "key1:value1, key2-value2!!@key3=value3";_x000D_
var matches = myString.matchAll(/(\w+)[:=-](\w+)/g);_x000D_
console.log([...matches]); // All match with capturing group values

The console.log([...matches]) shows

You may also get match value or specific group values using

let matchData = "key1:value1, key2-value2!!@key3=value3".matchAll(/(\w+)[:=-](\w+)/g)_x000D_
var matches = [...matchData]; // Note matchAll result is not re-iterable_x000D_
_x000D_
console.log(Array.from(matches, m => m[0])); // All match (Group 0) values_x000D_
// => [ "key1:value1", "key2-value2", "key3=value3" ]_x000D_
console.log(Array.from(matches, m => m[1])); // All match (Group 1) values_x000D_
// => [ "key1", "key2", "key3" ]

NOTE: See the browser compatibility details.

Here's a quick and dirty method that does what you want in a generic way. You'll need to add exception handling and you'll probably want to cache the BeanInfo types in a weakhashmap.

public Map<String, Object> getNonNullProperties(final Object thingy) {
    final Map<String, Object> nonNullProperties = new TreeMap<String, Object>();
    try {
        final BeanInfo beanInfo = Introspector.getBeanInfo(thingy
                .getClass());
        for (final PropertyDescriptor descriptor : beanInfo
                .getPropertyDescriptors()) {
            try {
                final Object propertyValue = descriptor.getReadMethod()
                        .invoke(thingy);
                if (propertyValue != null) {
                    nonNullProperties.put(descriptor.getName(),
                            propertyValue);
                }
            } catch (final IllegalArgumentException e) {
                // handle this please
            } catch (final IllegalAccessException e) {
                // and this also
            } catch (final InvocationTargetException e) {
                // and this, too
            }
        }
    } catch (final IntrospectionException e) {
        // do something sensible here
    }
    return nonNullProperties;
}

I have a Ryzen 2600X and I am able to run the emulator without problems. Here are the tweaks I made:

*NOTE: You don't need the beta version of Android Studio or Android Emulator.

1. Go to the MB bios and turn SVM on (CPU Virtualization).
2. In Windows right click Windows Button => Select "Apps and Features" => "Programs and features" => "Turn Windows Features on and off"
3. In the displayed list select Hyper-V checkbox == Make sure the subfolders are all selected. When prompted to restart, restart the PC.
4. After restart and update instalation screen you are back in Windows and you should be able to run the Emulator.

**Note: I have selected x86_64 and plain x86 images(both API 28) from the x86 Images tab and they work just fine.

***Note: Might also check for Android Licenses if errors pop up, I had an issue because of this while using Flutter, maybe it's related to that.

unfortunately none of the above worked. I finally could do it using the following stuffs: This solution works 100% (adapt it to your need)

I ve had this problem and it has started after importing our solution to TFS as a new project.I came across this topic and found a quick solution with some inspiration from your answers.

All i needed to do is to rebuild the project thats supposedly lost its metadata file and voila , problem solved.

elif and else must immediately follow the end of the if block, or Python will assume that the block has closed without them.

if 1:
    pass
             <--- this line must be indented at the same level as the `pass`
else:
    pass

In your code, the interpreter finishes the if block when the indentation, so the elif and the else aren't associated with it. They are thus being understood as standalone statements, which doesn't make sense.

In general, try to follow the style guidelines, which include removing excessive whitespace.

Yes you can connect your android app to your PHP to grab results from your database. Use a webservice to connect to your backend script via ASYNC task and http post requests. Check this link for more information Connecting to MySQL

When Command Extensions are enabled (Windows XP and newer, roughly), you can use the syntax %~nF (where F is the variable and ~n is the request for its name) to only get the filename.

FOR /R C:\Directory %F in (*.*) do echo %~nF

should echo only the filenames.

I have copied all library files from installer media databases/stage/ext/lib to $ORACLE_HOME/lib and it resolved the issue.

Another way to delete the migration:

$ rails d migration SameMigrationNameAsUsedToGenerate

Use it before rake db:migrate is executed because changes in database will stay forever :) - or remove changes in Database manually

When I used read.table, it assumed that the space after the first string meant the end of the data point and the second string was pushed to the next variable. I used sep= "\t" to solve the problem. I was using RStudio in a Mac OX environment. A previous solution was to transform .txt files to .csv in Excel, and afterwards open them with read.csv function.

Not sure if this is correct in any sense but this seems to work for me.

someHeader.h
inline int someVar;

I don't have linking/multiple definition issues and it "just works"... ;- )

It's quite handy for "quick" tests... Try to avoid global vars tho, because every says so... ;- )

The easiest way is to use a dedicated CSV class like this:

$csv = new csv();
$csv->load_data(array(
    array('name'=>'John', 'age'=>35),
    array('name'=>'Adrian', 'age'=>23), 
    array('name'=>'William', 'age'=>57) 
));
$csv->send_file('age.csv'); 

Use a memory stream

using(MemoryStream ms = new MemoryStream())
{
    image.Save(ms, ...);
    return ms.ToArray();
}

There are plenty of templating systems that offer more compact syntax for your views. Smarty is venerable and popular. This article lists 10 others.

Extension methods I commonly use to solve this problem:

public static string RemoveAfter(this string value, string character)
    {
        int index = value.IndexOf(character);
        if (index > 0)
        {
            value = value.Substring(0, index);
        }
        return value;
    }

    public static string RemoveBefore(this string value, string character)
    {
        int index = value.IndexOf(character);
        if (index > 0)
        {
            value = value.Substring(index + 1);
        }
        return value;
    }

It is not exactly answer of your question but it is a trick to tackle your problem.

export module Gender {

  export enum Type {
    Female = 1,
    Male = 2
  };

  export const List = Object.freeze([
    Type[Type.Female] ,
    Type[Type.Male]
  ]);

}

You can extend your list model in a way you want.

export const List = Object.freeze([
    { name: Type[Type.Female], value: Type.Female } ,
    { name: Type[Type.Male], value: Type.Male }
  ]);

Now, you can use it in this way:

for(const gender of Gender.List){
  console.log(gender.name);
  console.log(gender.value);
}

or:

if(i === Gender.Type.Male){
  console.log("I am a man.");
}

I found a solution for your reference. from some group divs select from group of two same class divs the first one

p[class*="myclass"]:not(:last-of-type) {color:red}
p[class*="myclass"]:last-of-type {color:green}

BTW, I don't know why :last-of-type works, but :first-of-type does not work.

My experiments on jsfiddle... https://jsfiddle.net/aspanoz/m1sg4496/

For the instance of

render :json => @projects, :include => :tasks

You are stating that you want to render @projects as JSON, and include the association tasks on the Project model in the exported data.

For the instance of

render :json => @projects, :callback => 'updateRecordDisplay'

You are stating that you want to render @projects as JSON, and wrap that data in a javascript call that will render somewhat like:

updateRecordDisplay({'projects' => []})

This allows the data to be sent to the parent window and bypass cross-site forgery issues.

As you stated in the comments, some of the values appeared to be floats, not strings. You will need to change it to strings before passing it to re.sub. The simplest way is to change location to str(location) when using re.sub. It wouldn't hurt to do it anyways even if it's already a str.

letters_only = re.sub("[^a-zA-Z]",  # Search for all non-letters
                          " ",          # Replace all non-letters with spaces
                          str(location))

I got this error on my ASP.Net 4.5 app on Windows Server 2012 R2.

Go to start menu -> "Turn windows features on or off". A wizard popped up for me.

Click Next to Server Roles

I had to check these to get this to work, located under Web Server IIS->Web Server-> Application Development (these are based on Jeremy Cook's answer above):

Then click next to Features and make sure the following is checked:

Then click next and Install. At this point, the error went away for me. Good luck!

Swift 5. Clean and simple.

if navigationController.presentingViewController != nil {
    // Navigation controller is being presented modally
}

In my case, in which I validate the most manually and using Firefox (43.0.4), minlength and validity.tooShort are not available unfortunately.

Since I only need to have minimum lengths stored to proceed, an easy and handy way is to assign this value to another valid attribute of the input tag. In that case then, you can use min, max, and step properties from [type="number"] inputs.

Rather than storing those limits in an array it's easier to find it stored in the same input instead of getting the element id to match the array index.

Quick hack:

def dowhile(func = None, condition = None):
    if not func or not condition:
        return
    else:
        func()
        while condition():
            func()

Use like so:

>>> x = 10
>>> def f():
...     global x
...     x = x - 1
>>> def c():
        global x
        return x > 0
>>> dowhile(f, c)
>>> print x
0

I guess the answer is, yes, there is an equivalent that will accomplish the same thing, integrated with Windows security.

In react, state will not change until you do it by using this.setState({});. That is why your console message showing old values.

I think it is better to update your "mysql-connector" lib package, so database can be still more safe.

I am using mysql of version 8.0.12. When I updated the mysql-connector-java to version 8.0.11, the problem was gone.

Simple solution is to run this query: mysql -h yourhostname -u username -p databasename < yoursqlfile.sql

And if you want to import with progress bar, try this: pv yoursqlfile.sql | mysql -uxxx -pxxxx databasename

Try with JQuery:

<script type="text/javascript">
function jquery_get_width_height()
{
    var imgWidth = $("#img").width();
    var imgHeight = $("#img").height();
    alert("JQuery -- " + "imgWidth: " + imgWidth + " - imgHeight: " + imgHeight);
}
</script>

or

<script type="text/javascript">
function javascript_get_width_height()
{
    var img = document.getElementById('img');
    alert("JavaSript -- " + "imgWidth: " + img.width + " - imgHeight: " + img.height);
}
</script>

Felipsmartins is correct.

It is worth mentioning that it is because you cannot really use the -d/--data option if this is not a POST request. But this is still possible if you use the -G option.

Which means you can do this:

curl -X DELETE -G 'http://localhost:5000/locations' -d 'id=3'

Here it is a bit silly but when you are on the command line and you have a lot of parameters, it is a lot tidier.

I am saying this because cURL commands are usually quite long, so it is worth making it on more than one line escaping the line breaks.

curl -X DELETE -G \
'http://localhost:5000/locations' \
-d id=3 \
-d name=Mario \
-d surname=Bros

This is obviously a lot more comfortable if you use zsh. I mean when you need to re-edit the previous command because zsh lets you go line by line. (just saying)

Hope it helps.

Converting the retreived data from the request object to json object is as below using google-gson

Gson gson = new Gson();
ABCClass c1 = gson.fromJson(data, ABCClass.class);

//ABC class is a class whose strcuture matches to the data variable retrieved

In my opinion you should not load and use plugins you don't have to. This particular jQuery plugin doesn't give you anything since directly using the JavaScript sessionStorage object is exactly the same level of complexity. Nor, does the plugin provide some easier way to interact with other jQuery functionality. In addition the practice of using a plugin discourages a deep understanding of how something works. sessionStorage should be used only if its understood. If its understood, then using the jQuery plugin is actually MORE effort.

Consider using sessionStorage directly: https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Storage#sessionStorage

Anyone else stumbling upon this answer should note that jQuery now (>=1.3) has outerHeight/outerWidth functions to retrieve the width including padding/borders, e.g.

$(elem).outerWidth(); // Returns the width + padding + borders

To include the margin as well, simply pass true:

$(elem).outerWidth( true ); // Returns the width + padding + borders + margins

Assuming you really mean easiest and are not necessarily looking for a way to do this programmatically, you can do this:

1. Add, if not already there, a row of "column Musicians" to the spreadsheet. That is, if you have data in columns such as:

   Rory Gallagher      Guitar
   Gerry McAvoy        Bass
   Rod de'Ath          Drums
   Lou Martin          Keyboards
   Donkey Kong Sioux   Self-Appointed Semi-official Stomper
   

   Note: you might want to add "Musician" and "Instrument" in row 0 (you might have to insert a row there)

2. Save the file as a CSV file.

3. Copy the contents of the CSV file to the clipboard

4. Go to http://www.convertcsv.com/csv-to-json.htm

5. Verify that the "First row is column names" checkbox is checked

6. Paste the CSV data into the content area

7. Mash the "Convert CSV to JSON" button

   With the data shown above, you will now have:

   [
     {
       "MUSICIAN":"Rory Gallagher",
       "INSTRUMENT":"Guitar"
     },
     {
       "MUSICIAN":"Gerry McAvoy",
       "INSTRUMENT":"Bass"
     },
     {
       "MUSICIAN":"Rod D'Ath",
       "INSTRUMENT":"Drums"
     },
     {
       "MUSICIAN":"Lou Martin",
       "INSTRUMENT":"Keyboards"
     }
     {
       "MUSICIAN":"Donkey Kong Sioux",
       "INSTRUMENT":"Self-Appointed Semi-Official Stomper"
     }
   ]
   

   With this simple/minimalistic data, it's probably not required, but with large sets of data, it can save you time and headache in the proverbial long run by checking this data for aberrations and abnormalcy.

8. Go here: http://jsonlint.com/

9. Paste the JSON into the content area

10. Pres the "Validate" button.

If the JSON is good, you will see a "Valid JSON" remark in the Results section below; if not, it will tell you where the problem[s] lie so that you can fix it/them.

You can simply do something like...

...
<head>
...
<script>
  window.fbAsyncInit = function() {
    FB.init({
      appId            : 'your-app-id', // you need to create an facebook app
      autoLogAppEvents : true,
      xfbml            : true,
      version          : 'v3.3'
    });
  };
</script>
<script async defer src="https://connect.facebook.net/en_US/sdk.js"></script>
</head>
<body>
...
<button id="share-btn"></button>
<!-- load jquery -->
<script>
    $('#share-btn').on('click', function () {
        FB.ui({
            method: 'share',
            href: location.href, // Current url
        }, function (response) { });
    });
</script>
</body>

Simple way

<select class ="dropdownstyle" name="category" selected="<?php print($messageeditdetails[0]['category_id']); ?>">

<option value=""><?php echo "Select"; ?></option>

<?php  foreach ($dropdowndetails as $dropdowndetails) { ?>
    <option <?php if($messageeditdetails[0]['category_id'] == $dropdowndetails['id']) { ?> selected="<?php echo $dropdowndetails['id']; ?>" <?php } ?> value="<?php echo $dropdowndetails['id']; ?>"><?php echo $dropdowndetails['category_name']; ?></option>
<?php } ?>
</select>

Try this:

$("input:checkbox").hasClass("myClass");

In my case it had to do with the Microsoft.Build.Bcl version. My nuget package version was 1.0.21, but my project files were still pointing to version 1.0.14

So I changed my .csproj files from:

  <Import Project="..\..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets" Condition="Exists('..\..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" />
   <Target Name="EnsureBclBuildImported" BeforeTargets="BeforeBuild" Condition="'$(BclBuildImported)' == ''">
    <Error Condition="!Exists('..\..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" Text="This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=317567." HelpKeyword="BCLBUILD2001" />
    <Error Condition="Exists('..\..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" Text="The build restored NuGet packages. Build the project again to include these packages in the build. For more information, see http://go.microsoft.com/fwlink/?LinkID=317568." HelpKeyword="BCLBUILD2002" />
  </Target>

to:

 <Import Project="..\..\packages\Microsoft.Bcl.Build.1.0.21\build\Microsoft.Bcl.Build.targets" Condition="Exists('..\..\packages\Microsoft.Bcl.Build.1.0.21\build\Microsoft.Bcl.Build.targets')" />
  <Target Name="EnsureBclBuildImported" BeforeTargets="BeforeBuild" Condition="'$(BclBuildImported)' == ''">
    <Error Condition="!Exists('..\..\packages\Microsoft.Bcl.Build.1.0.21\build\Microsoft.Bcl.Build.targets')" Text="This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=317567." HelpKeyword="BCLBUILD2001" />
    <Error Condition="Exists('..\..\packages\Microsoft.Bcl.Build.1.0.21\build\Microsoft.Bcl.Build.targets')" Text="The build restored NuGet packages. Build the project again to include these packages in the build. For more information, see http://go.microsoft.com/fwlink/?LinkID=317568." HelpKeyword="BCLBUILD2002" />

And the build was working again.

See perldoc/perlfaq:

Remember that int() merely truncates toward 0. For rounding to a certain number of digits, sprintf() or printf() is usually the easiest route.

 printf("%.3f",3.1415926535);
 # prints 3.142

The POSIX module (part of the standard Perl distribution) implements ceil(), floor(), and a number of other mathematical and trigonometric functions.

use POSIX;
$ceil  = ceil(3.5); # 4
$floor = floor(3.5); # 3

In 5.000 to 5.003 perls, trigonometry was done in the Math::Complex module.

With 5.004, the Math::Trig module (part of the standard Perl distribution) > implements the trigonometric functions.

Internally it uses the Math::Complex module and some functions can break out from the real axis into the complex plane, for example the inverse sine of 2.

Rounding in financial applications can have serious implications, and the rounding method used should be specified precisely. In these cases, it probably pays not to trust whichever system rounding is being used by Perl, but to instead implement the rounding function you need yourself.

To see why, notice how you'll still have an issue on half-way-point alternation:

for ($i = 0; $i < 1.01; $i += 0.05)
{
   printf "%.1f ",$i
}

0.0 0.1 0.1 0.2 0.2 0.2 0.3 0.3 0.4 0.4 0.5 0.5 0.6 0.7 0.7 0.8 0.8 0.9 0.9 1.0 1.0

Don't blame Perl. It's the same as in C. IEEE says we have to do this. Perl numbers whose absolute values are integers under 2**31 (on 32 bit machines) will work pretty much like mathematical integers. Other numbers are not guaranteed.

You can use the below method, which will take your target URL as the only input (Don't forget http://)

void GoToURL(String url){
    Uri uri = Uri.parse(url);
    Intent intent= new Intent(Intent.ACTION_VIEW,uri);
    startActivity(intent);
}

Just tested and QDir::currentPath() does return the path from which I called my executable.

And a symlink does not "exist". If you are executing an exe from that path you are effectively executing it from the path the symlink points to.

Make sure to delete ~/.bash_profile and ~/.bash_login so that .profile can work. This worked for me http://johnnywey.wordpress.com/2008/04/17/fixing-bash-profile-in-os-x/

Yeah, for most cases, you don't need to create a class with getters and setters. Just create a new Dictionary and bind it to the data source. Here's an example in VB using a for loop to set the DisplayMember and ValueMember of a combo box from a list:

        Dim comboSource As New Dictionary(Of String, String)()
        cboMenu.Items.Clear()
        For I = 0 To SomeList.GetUpperBound(0)
            comboSource.Add(SomeList(I).Prop1, SomeList(I).Prop2)
        Next I
        cboMenu.DataSource = New BindingSource(comboSource, Nothing)
        cboMenu.DisplayMember = "Value"
        cboMenu.ValueMember = "Key"

Then you can set up a data grid view's rows according to the value or whatever you need by calling a method on click:

Private Sub cboMenu_SelectedIndexChanged(sender As Object, e As EventArgs) Handles cboMenu.SelectionChangeCommitted
    SetListGrid(cboManufMenu.SelectedValue)
End Sub

Use DATEADD:

DATEADD(month, 1, reference_dt)

First off you can't have just a number for your id unless you are using the HTML5 DOCTYPE. Secondly, you need to either remove the # in each id or replace it with this:

$container.cycle(id.replace('#','')); 

var data = {_x000D_
  "items": [{_x000D_
    "id": 1,_x000D_
    "category": "cat1"_x000D_
  }, {_x000D_
    "id": 2,_x000D_
    "category": "cat2"_x000D_
  }, {_x000D_
    "id": 3,_x000D_
    "category": "cat1"_x000D_
  }, {_x000D_
    "id": 4,_x000D_
    "category": "cat2"_x000D_
  }, {_x000D_
    "id": 5,_x000D_
    "category": "cat1"_x000D_
  }]_x000D_
};_x000D_
//Filters an array of numbers to include only numbers bigger then zero._x000D_
//Exact Data you want..._x000D_
var returnedData = $.grep(data.items, function(element) {_x000D_
  return element.category === "cat1" && element.id === 3;_x000D_
}, false);_x000D_
console.log(returnedData);_x000D_
$('#id').text('Id is:-' + returnedData[0].id)_x000D_
$('#category').text('Category is:-' + returnedData[0].category)_x000D_
//Filter an array of numbers to include numbers that are not bigger than zero._x000D_
//Exact Data you don't want..._x000D_
var returnedOppositeData = $.grep(data.items, function(element) {_x000D_
  return element.category === "cat1";_x000D_
}, true);_x000D_
console.log(returnedOppositeData);

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<p id='id'></p>_x000D_

The $.grep() method eliminates items from an array as necessary so that only remaining items carry a given search. The test is a function that is passed an array item and the index of the item within the array. Only if the test returns true will the item be in the result array.

There is an article with a working idea on how to request oAuth authorization before loading static content dynamically:

Securing Site That Runs on Github Pages With JSON Backend In Private Repository

Content should be stored in a secret GitHub repository with a viewer having read access to it. GitHub pages stores only the serving JS code.

Edit the build path in this order, this worked for me.

Make sure the /gen is before /src

When you use the exec() function, it is as though you have a cmd terminal open and are typing commands straight to it.

Use single quotes like this $str = exec('start /B Path\to\batch.bat');
The /B means the bat will be executed in the background so the rest of the php will continue after running that line, as opposed to $str = exec('start /B /C command', $result); where command is executed and then result is stored for later use.

PS: It works for both Windows and Linux.
More details are here http://www.php.net/manual/en/function.exec.php :)

This can be archived by adding code on the onchange event of the select control.

For Example:

<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">
    <option value="http://gmail.com">Gmail</option>
    <option value="http://youtube.com">Youtube</option>
</select>

Try opening config-db.php, it's inside /etc/phpmyadmin. In my case, the user was phpmyadmin, and my password was correct. Maybe your problem is that you're using the usual 'root' username, and your password could be correct.

var d = new Date();
console.log(d.valueOf()); 

All values of column A that are not present in column B will have a red background. Hope that it helps as starting point.

Sub highlight_missings()
Dim i As Long, lastA As Long, lastB As Long
Dim compare As Variant
Range("A:A").ClearFormats
lastA = Range("A65536").End(xlUp).Row
lastB = Range("B65536").End(xlUp).Row

For i = 2 To lastA
    compare = Application.Match(Range("a" & i), Range("B2:B" & lastB), 0)
        If IsError(compare) Then
            Range("A" & i).Interior.ColorIndex = 3
        End If
Next i
End Sub

xmp is the way to go, i.e.:

<xmp>
  # your code...
</xmp>

This will check if particular email address exist in the table:

if (isset(User::where('email', Input::get('email'))->value('email')))
{
    // Input::get('email') exist in the table 
}

In my case, I had to install "libz.so.1" library to make it work, on Ubuntu 15.04

sudo apt-get install lib32z1

Had this error when importing project from Eclipse. The reason was some of the xml files had errors. Check ALL your XML files for errors. Including androidmanifest.xml, and values, themes, styles, layouts folders, etc. Warnings in xml are ok, but errors will generate this error.

Afterwards, do a Clean Project and rebuild.

Does your find have the -mmin option? That can let you test the number of mins since last modification:

find $LOCATION -name $REQUIRED_FILES -type f -mmin +360 -delete

Or maybe look at using tmpwatch to do the same job. phjr also recommended tmpreaper in the comments.

Here is a solution by Andreas Joseph Krogh from the PostgreSQL mailing list: http://www.postgresql.org/message-id/[email protected]

SELECT source_table::regclass, source_attr.attname AS source_column,
    target_table::regclass, target_attr.attname AS target_column
FROM pg_attribute target_attr, pg_attribute source_attr,
  (SELECT source_table, target_table, source_constraints[i] source_constraints, target_constraints[i] AS target_constraints
   FROM
     (SELECT conrelid as source_table, confrelid AS target_table, conkey AS source_constraints, confkey AS target_constraints,
       generate_series(1, array_upper(conkey, 1)) AS i
      FROM pg_constraint
      WHERE contype = 'f'
     ) query1
  ) query2
WHERE target_attr.attnum = target_constraints AND target_attr.attrelid = target_table AND
      source_attr.attnum = source_constraints AND source_attr.attrelid = source_table;

This solution handles foreign keys that reference multiple columns, and avoids duplicates (which some of the other answers fail to do). The only thing I changed were the variable names.

Here is an example that returns all employee columns that reference the permission table:

SELECT source_column
FROM foreign_keys
WHERE source_table = 'employee'::regclass AND target_table = 'permission'::regclass;

There is a better solution now: Vertical align anything with just 3 lines of CSS

There is also good old POSIX system("echo -en '\007'");

I know it has been a while since this was asked, but I learned an alternative yesterday

We all know you can do:

if(o instanceof String) {   // etc

but what if you dont know exactly what type of class it needs to be? you cannot generically do:

if(o instanceof <Class variable>.getClass()) {   

as it gives a compile error.
Instead, here is an alternative - isAssignableFrom()

For example:

public static boolean isASubClass(Class classTypeWeWant, Object objectWeHave) {

    return classTypeWeWant.isAssignableFrom(objectWeHave.getClass())
}

First of all scipy.misc.imread and PIL are no longer available. Instead use imageio library but you need to install Pillow for that as a dependancy

pip install Pillow imageio

Then use the following code to load the image and get the details about it.

import imageio
import tensorflow as tf

path = 'your_path_to_image' # '~/Downloads/image.png'

img = imageio.imread(path)
print(img.shape) 

or

img_tf = tf.Variable(img)
print(img_tf.get_shape().as_list()) 

both work fine.

I had this in VS 2012 where the "Section name" had been changed in a project, and I fixed it by deleting "app.config" in the project, then right-clicking on the project in the "Solution Explorer", selecting "Properties", then "Settings", then making a change to one of the settings, saving, and re-building. This created a new app.config with the correct information.

The answer provided by @DSM is simple and straightforward, but I thought I'd add my own input to this question. If you look at the code for pandas.value_counts, you'll see that there is a lot going on.

If you need to calculate the frequency of many series, this could take a while. A faster implementation would be to use numpy.unique with return_counts = True

Here is an example:

import pandas as pd
import numpy as np

my_series = pd.Series([1,2,2,3,3,3])

print(my_series.value_counts())
3    3
2    2
1    1
dtype: int64

Notice here that the item returned is a pandas.Series

In comparison, numpy.unique returns a tuple with two items, the unique values and the counts.

vals, counts = np.unique(my_series, return_counts=True)
print(vals, counts)
[1 2 3] [1 2 3]

You can then combine these into a dictionary:

results = dict(zip(vals, counts))
print(results)
{1: 1, 2: 2, 3: 3}

And then into a pandas.Series

print(pd.Series(results))
1    1
2    2
3    3
dtype: int64

Whenever you are trying to compare the strings, compare them with respect to each character. For this you can use built in string function called strcmp(input1,input2); and you should use the header file called #include<string.h>

Try this code:

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

int main() 
{ 
    char s[]="STACKOVERFLOW";
    char s1[200];
    printf("Enter the string to be checked\n");//enter the input string
    scanf("%s",s1);
    if(strcmp(s,s1)==0)//compare both the strings  
    {
        printf("Both the Strings match\n"); 
    } 
    else
    {
        printf("Entered String does not match\n");  
    } 
    system("pause");  
} 

Try using this:

$description = preg_replace("/\r\n|\r|\n/", '<br/>', $description);

You can do it with a sub-query:

SELECT * FROM (
    SELECT * FROM table ORDER BY id DESC LIMIT 50
) sub
ORDER BY id ASC

This will select the last 50 rows from table, and then order them in ascending order.

Create label in swift 4

 let label = UILabel(frame: CGRect(x: self.view.frame.origin.x, y: self.view.frame.origin.y, width: self.view.frame.size.width, height: 50))
    label.textAlignment = .center
    label.text = "Hello this my label"

    //To set the color
    label.backgroundColor = UIColor.white
    label.textColor = UIColor.black

    //To set the font Dynamic
    label.font = UIFont(name: "Helvetica-Regular", size: 20.0)

    //To set the system font
    label.font = UIFont.systemFont(ofSize: 20.0)

    //To display multiple lines
    label.numberOfLines = 0
    label.lineBreakMode = .byWordWrapping //Wrap the word of label
    label.lineBreakMode = .byCharWrapping //Wrap the charactor of label

    label.sizeToFit()
    self.view.addSubview(label)

If you are using PHPMyAdmin You can be solved this issue by doing this:

CAUTION: Don't use this solution if you want to maintain existing records in your table.

Step 1: Select database export method to custom:

Step 2: Please make sure to check truncate table before insert in data creation options:

Now you are able to import this database successfully.

Unfortunately there is nothing like this in TypeScript (more details here: https://github.com/Microsoft/TypeScript/issues/467)

But to get around this you can change your params to be an interface:

export interface IErrorParams {
  message: string;
  title?: string;
  autoHideAfter?: number;
}

export interface INotificationService {
  error(params: IErrorParams);
}

//then to call it:
error({message: 'msg', autoHideAfter: 42});

Here's a complete example of how it can be done. However you need flashback query privileges on the child table.

Here's the setup.

create table parent_tab
  (parent_id number primary key,
  val varchar2(20));

create table child_tab
    (child_id number primary key,
    parent_id number,
    child_val number,
     constraint child_par_fk foreign key (parent_id) references parent_tab);

insert into parent_tab values (1,'Red');
insert into parent_tab values (2,'Green');
insert into parent_tab values (3,'Blue');
insert into parent_tab values (4,'Black');
insert into parent_tab values (5,'White');

insert into child_tab values (10,1,100);
insert into child_tab values (20,3,100);
insert into child_tab values (30,3,100);
insert into child_tab values (40,4,100);
insert into child_tab values (50,5,200);

commit;

select * from parent_tab
where parent_id not in (select parent_id from child_tab);

Now delete a subset of the children (ones with parents 1,3 and 4 - but not 5).

delete from child_tab where child_val = 100;

Then get the parent_ids from the current COMMITTED state of the child_tab (ie as they were prior to your deletes) and remove those that your session has NOT deleted. That gives you the subset that have been deleted. You can then delete those out of the parent_tab

delete from parent_tab
where parent_id in
  (select parent_id from child_tab as of scn dbms_flashback.get_system_change_number
  minus
  select parent_id from child_tab);

'Green' is still there (as it didn't have an entry in the child table anyway) and 'Red' is still there (as it still has an entry in the child table)

select * from parent_tab
where parent_id not in (select parent_id from child_tab);

select * from parent_tab;

It is an exotic/unusual operation, so if i was doing it I'd probably be a bit cautious and lock both child and parent tables in exclusive mode at the start of the transaction. Also, if the child table was big it wouldn't be particularly performant so I'd opt for a PL/SQL solution like Rajesh's.

Your second way is correct.

def foo(opts: dict = {}):
    pass

print(foo.__annotations__)

this outputs

{'opts': <class 'dict'>}

It's true that's it's not listed in PEP 484, but type hints are an application of function annotations, which are documented in PEP 3107. The syntax section makes it clear that keyword arguments works with function annotations in this way.

I strongly advise against using mutable keyword arguments. More information here.

HTML

<div id="myparent">
  <div id="mychild">Test Content here</div>
</div>

CSS

#myparent {
  display: table;
}
#mychild {
  display: table-cell;
  vertical-align: middle;
}

We set the parent div to display as a table and the child div to display as a table-cell. We can then use vertical-align on the child div and set its value to middle. Anything inside this child div will be vertically centered.

you can use OFFSET and FETCH NEXT

SELECT id
FROM tablename
ORDER BY column
OFFSET 1 ROWS
FETCH NEXT 1 ROWS ONLY;

NOTE:

OFFSET can only be used with ORDER BY clause. It cannot be used on its own.

OFFSET value must be greater than or equal to zero. It cannot be negative, else return error.

The OFFSET argument is used to identify the starting point to return rows from a result set. Basically, it exclude the first set of records.

The FETCH argument is used to return a set of number of rows. FETCH can’t be used itself, it is used in conjuction with OFFSET.

As often, numbers says more than feeling, here are some data: Pipe vs Unix Socket Performance (opendmx.net).

This benchmark shows a difference of about 12 to 15% faster speed for pipes.

Here is an example:

I've an Order table with a DateTime field called OrderDate. I want to retrieve all orders where the order date is equals to 01/01/2006. there are next ways to do it:

1) WHERE DateDiff(dd, OrderDate, '01/01/2006') = 0
2) WHERE Convert(varchar(20), OrderDate, 101) = '01/01/2006'
3) WHERE Year(OrderDate) = 2006 AND Month(OrderDate) = 1 and Day(OrderDate)=1
4) WHERE OrderDate LIKE '01/01/2006%'
5) WHERE OrderDate >= '01/01/2006'  AND OrderDate < '01/02/2006'

I use Hibernate Validator via @Valid for all input objects (binding and @RequestBody json, see https://dzone.com/articles/spring-31-valid-requestbody). So @org.hibernate.validator.constraints.SafeHtml is a good solution for me.

Hibernate SafeHtmlValidator depends on org.jsoup, so it's needed to add one more project dependencies:

<dependency>
    <groupId>org.jsoup</groupId>
    <artifactId>jsoup</artifactId>
    <version>1.10.1</version>
</dependency>

For bean User with field

@NotEmpty
@SafeHtml
protected String name;

for update attempt with value <script>alert(123)</script> in controller

@PutMapping(value = "/{id}", consumes = MediaType.APPLICATION_JSON_VALUE)
public void update(@Valid @RequestBody User user, @PathVariable("id") int id) 

or

@PostMapping
public void createOrUpdate(@Valid User user) {

is thrown BindException for binding and MethodArgumentNotValidException for @RequestBody with default message:

name may have unsafe html content

Validator works as well for binding, as before persisting. Apps could be tested at http://topjava.herokuapp.com/

UPDATE: see also comment from @GuyT

CVE-2019-10219 and status of @SafeHtml

We have been made aware of a CVE-2019-10219 related to the @SafeHtml constraint and it was fixed in both 6.0.18.Final and 6.1.0.Final....

However, we came to the conclusion that the @SafeHtml constraint was fragile, highly security-sensitive and depending on an external library that wasn’t designed for this purpose. Having it included in core Hibernate Validator was not a very good idea. That’s why we deprecated it and marked it for removal.There is no magic plan here so our users will have to maintain this constraint themselves

Resume for myself: it is safe and could be used, until solution better be found.

Here is a clean way to disable and enable submit button:

<input type="submit" name="sendNewSms" class="inputButton" id="sendNewSms" value=" Send " />
<input type="checkbox" id="disableBtn" />

var submit = document.getElementById('sendNewSms'),
    checkbox = document.getElementById('disableBtn'),
    disableSubmit = function(e) {
        submit.disabled = this.checked
    };

checkbox.addEventListener('change', disableSubmit);

to_char actually lets you pull out the Year and month in one fell swoop!

select to_char(date('2014-05-10'),'YYYY-MM') as year_month; --'2014-05'

or in the case of the user's example above:

select to_char(date,'YY-Mon') as year_month
       sum("Sales") as "Sales"
from some_table
group by 1;

ggVG

I solved it this way:

$ brew uninstall --force node
$ brew uninstall --force npm

after it

$ brew install node

which suggested me to overwrite simlinks

  rm '/usr/local/share/doc/node/gdbinit'

To force the link and overwrite all conflicting files:
  brew link --overwrite node

after executing

$ brew link --overwrite node

everything worked again.

Update: Corrected map rendering algorithm, added more illustrations, changed formating.

Perhaps the advantage for the "zig-zag" technique for mapping the tiles to the screen can be said that the tile's x and y coordinates are on the vertical and horizontal axes.

"Drawing in a diamond" approach:

By drawing an isometric map using "drawing in a diamond", which I believe refers to just rendering the map by using a nested for-loop over the two-dimensional array, such as this example:

tile_map[][] = [[...],...]

for (cellY = 0; cellY < tile_map.size; cellY++):
    for (cellX = 0; cellX < tile_map[cellY].size cellX++):
        draw(
            tile_map[cellX][cellY],
            screenX = (cellX * tile_width  / 2) + (cellY * tile_width  / 2)
            screenY = (cellY * tile_height / 2) - (cellX * tile_height / 2)
        )

Advantage:

The advantage to the approach is that it is a simple nested for-loop with fairly straight forward logic that works consistently throughout all tiles.

Disadvantage:

One downside to that approach is that the x and y coordinates of the tiles on the map will increase in diagonal lines, which might make it more difficult to visually map the location on the screen to the map represented as an array:

However, there is going to be a pitfall to implementing the above example code -- the rendering order will cause tiles that are supposed to be behind certain tiles to be drawn on top of the tiles in front:

In order to amend this problem, the inner for-loop's order must be reversed -- starting from the highest value, and rendering toward the lower value:

tile_map[][] = [[...],...]

for (i = 0; i < tile_map.size; i++):
    for (j = tile_map[i].size; j >= 0; j--):  // Changed loop condition here.
        draw(
            tile_map[i][j],
            x = (j * tile_width / 2) + (i * tile_width / 2)
            y = (i * tile_height / 2) - (j * tile_height / 2)
        )

With the above fix, the rendering of the map should be corrected:

"Zig-zag" approach:

Advantage:

Perhaps the advantage of the "zig-zag" approach is that the rendered map may appear to be a little more vertically compact than the "diamond" approach:

Disadvantage:

From trying to implement the zig-zag technique, the disadvantage may be that it is a little bit harder to write the rendering code because it cannot be written as simple as a nested for-loop over each element in an array:

tile_map[][] = [[...],...]

for (i = 0; i < tile_map.size; i++):
    if i is odd:
        offset_x = tile_width / 2
    else:
        offset_x = 0

    for (j = 0; j < tile_map[i].size; j++):
        draw(
            tile_map[i][j],
            x = (j * tile_width) + offset_x,
            y = i * tile_height / 2
        )

Also, it may be a little bit difficult to try to figure out the coordinate of a tile due to the staggered nature of the rendering order:

Note: The illustrations included in this answer were created with a Java implementation of the tile rendering code presented, with the following int array as the map:

tileMap = new int[][] {
    {0, 1, 2, 3},
    {3, 2, 1, 0},
    {0, 0, 1, 1},
    {2, 2, 3, 3}
};

The tile images are:

• tileImage[0] -> A box with a box inside.
• tileImage[1] -> A black box.
• tileImage[2] -> A white box.
• tileImage[3] -> A box with a tall gray object in it.

A Note on Tile Widths and Heights

The variables tile_width and tile_height which are used in the above code examples refer to the width and height of the ground tile in the image representing the tile:

Using the dimensions of the image will work, as long as the image dimensions and the tile dimensions match. Otherwise, the tile map could be rendered with gaps between the tiles.

I don't understand

days, hours, minutes = td.days, td.seconds // 3600, td.seconds // 60 % 60

how about this

days, hours, minutes = td.days, td.seconds // 3600, td.seconds % 3600 / 60.0

You get minutes and seconds of a minute as a float.

It's not working because the entire for loop (from the for to the final closing parenthesis, including the commands between those) is being evaluated when it's encountered, before it begins executing.

In other words, %count% is replaced with its value 1 before running the loop.

What you need is something like:

setlocal enableextensions enabledelayedexpansion
set /a count = 1
for /f "tokens=*" %%a in (config.properties) do (
  set /a count += 1
  echo !count!
)
endlocal

Delayed expansion using ! instead of % will give you the expected behaviour. See also here.

Also keep in mind that setlocal/endlocal actually limit scope of things changed inside so that they don't leak out. If you want to use count after the endlocal, you have to use a "trick" made possible by the very problem you're having:

endlocal && set count=%count%

Let's say count has become 7 within the inner scope. Because the entire command is interpreted before execution, it effectively becomes:

endlocal && set count=7

Then, when it's executed, the inner scope is closed off, returning count to it's original value. But, since the setting of count to seven happens in the outer scope, it's effectively leaking the information you need.

You can string together multiple sub-commands to leak as much information as you need:

endlocal && set count=%count% && set something_else=%something_else%

The type attribute is used to define the MIME type within the HTML document. Depending on what DOCTYPE you use, the type value is required in order to validate the HTML document.

The language attribute lets the browser know what language you are using (Javascript vs. VBScript) but is not necessarily essential and, IIRC, has been deprecated.

I personally prefer the trick of using a hidden pseudo element to span the full height of the outer container, and vertically aligning it with the other content. Chris Coyier has a nice article on the technique. http://css-tricks.com/centering-in-the-unknown/ The huge advantage of this is scalability. You don't have to know the height of the content or worry about it growing/shrinking. This solution scales :).

Here's a fiddle with all the CSS you'll need and a working example. http://jsfiddle.net/m5sLze0d/

.center:before {
    content: ""; /* Adding Extra Space Above Element */
    display: inline-block;

    vertical-align: middle;
}
.center_element {
    display:inline-block;

    vertical-align:middle;
    white-space:normal;
    text-align:left;
}

.newLine() is the best if your system property line.separator is proper . and sometime you don't want to change the property runtime . So alternative solution is appending \n

How about using %/sprintf:

i = 20
"%x" % i  #=> "14"

Can you set the ActionBar before you set the Contient View? This order would be better:

 @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ActionBar actionBar =getSupportActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);            
  }

I find this simple T-SQL query useful for returning valid e-mail addresses

SELECT email
FROM People
WHERE email LIKE '%_@__%.__%' 
    AND PATINDEX('%[^a-z,0-9,@,.,_]%', REPLACE(email, '-', 'a')) = 0

The PATINDEX bit eliminates all e-mail addresses containing characters that are not in the allowed a-z, 0-9, '@', '.', '_' & '-' set of characters.

It can be reversed to do what you want like this:

SELECT email
FROM People
WHERE NOT (email LIKE '%_@__%.__%' 
    AND PATINDEX('%[^a-z,0-9,@,.,_]%', REPLACE(email, '-', 'a')) = 0)

In terminal type :

netstat -anp|grep "port_number"

It will show the port details. Go to last column. It will be in this format . For example :- PID/java

then execute :

kill -9 PID. Worked on Centos5

For MAC:

lsof -n -i :'port-number' | grep LISTEN

Sample Response :

java   4744 (PID)  test  364u  IP0 asdasdasda   0t0  TCP *:port-number (LISTEN)

and then execute :

kill -9 PID

Date.prototype.addDays = function(days) {

   var dat = new Date(this.valueOf())
   dat.setDate(dat.getDate() + days);
   return dat;

function getDates(startDate, stopDate) {

  var dateArray = new Array();
  var currentDate = startDate;
  while (currentDate <= stopDate) {
    dateArray.push(currentDate);
    currentDate = currentDate.addDays(1);
  }
  return dateArray;
}

var dateArray = getDates(new Date(), (new Date().addDays(7)));

for (i = 0; i < dateArray.length; i ++ ) {
  //  alert (dateArray[i]);

    date=('0'+dateArray[i].getDate()).slice(-2);
    month=('0' +(dateArray[i].getMonth()+1)).slice(-2);
    year=dateArray[i].getFullYear();
    alert(date+"-"+month+"-"+year );
}

Using .on() you can define your function once, and it will execute for any dynamically added elements.

for example

$('#staticDiv').on('click', 'yourSelector', function() {
  //do something
});

if you are using FragmentActivity. then do like this

first call This inside your Fragment.

public void callParentMethod(){
    getActivity().onBackPressed();
}

and then Call onBackPressed method in side your parent FragmentActivity class.

@Override
public void onBackPressed() {
  //super.onBackPressed();
  //create a dialog to ask yes no question whether or not the user wants to exit
  ...
}

You neglected to say which version of C you are concerned about. Let's assume it's this one:

http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf

As you can see by reading the specification, the standard definitions of true and false are 1 and 0, yes.

If your question is about a different version of C, or about non-standard definitions for true and false, then ask a more specific question.

The location=1 part should enable an editable location bar.

As a side note, you can drop the language="javascript" attribute from your script as it is now deprecated.

update:

Setting the statusbar=1 to the correct parameter status=1 works for me

You can use CAST function:

SELECT CAST(your_column_name AS varchar(10)) FROM your_table_name
