There is similar issue. I added listener as given here

https://stackoverflow.com/questions/3145936/spring-security-j-spring-security-logout-problem

It worked for me adding below lines to web.xml. Posting it very late, should help someone looking for answer.

<listener>
    <listener-class> org.springframework.security.web.session.HttpSessionEventPublisher</listener-class>
</listener>

You're looking for this on the command line (for a class called MyClass):

On Unix/Linux:

javap -verbose MyClass | grep "major"

On Windows:

javap -verbose MyClass | findstr "major"

You want the major version from the results. Here are some example values:

• Java 1.2 uses major version 46
• Java 1.3 uses major version 47
• Java 1.4 uses major version 48
• Java 5 uses major version 49
• Java 6 uses major version 50
• Java 7 uses major version 51
• Java 8 uses major version 52
• Java 9 uses major version 53
• Java 10 uses major version 54
• Java 11 uses major version 55

I gave it a try a while back (also: on GitHub). My implementation had some problems, which I won't get into here. Let me tell you, more importantly, what I learned.

Firstly, there's no way you're going to get a full implementation of IList<T> that is lockless and thread-safe. In particular, random insertions and removals are not going to work, unless you also forget about O(1) random access (i.e., unless you "cheat" and just use some sort of linked list and let the indexing suck).

What I thought might be worthwhile was a thread-safe, limited subset of IList<T>: in particular, one that would allow an Add and provide random read-only access by index (but no Insert, RemoveAt, etc., and also no random write access).

This was the goal of my ConcurrentList<T> implementation. But when I tested its performance in multithreaded scenarios, I found that simply synchronizing adds to a List<T> was faster. Basically, adding to a List<T> is lightning fast already; the complexity of the computational steps involved is miniscule (increment an index and assign to an element in an array; that's really it). You would need a ton of concurrent writes to see any sort of lock contention on this; and even then, the average performance of each write would still beat out the more expensive albeit lockless implementation in ConcurrentList<T>.

In the relatively rare event that the list's internal array needs to resize itself, you do pay a small cost. So ultimately I concluded that this was the one niche scenario where an add-only ConcurrentList<T> collection type would make sense: when you want guaranteed low overhead of adding an element on every single call (so, as opposed to an amortized performance goal).

It's simply not nearly as useful a class as you would think.

Just want to share another option:

# mark two objects to be deleted
session.delete(obj1)
session.delete(obj2)

# commit (or flush)
session.commit()

http://docs.sqlalchemy.org/en/latest/orm/session_basics.html#deleting

In this example, the following codes shall works fine:

obj = User.query.filter_by(id=123).one()
session.delete(obj)
session.commit()

As of Entity Framework 4.3, there is an AddOrUpdate method at namespace System.Data.Entity.Migrations:

public static void AddOrUpdate<TEntity>(
    this IDbSet<TEntity> set,
    params TEntity[] entities
)
where TEntity : class

which by the doc:

Adds or updates entities by key when SaveChanges is called. Equivalent to an "upsert" operation from database terminology. This method can be useful when seeding data using Migrations.

To answer the comment by @Smashing1978, I will paste relevant parts from link provided by @Colin

The job of AddOrUpdate is to ensure that you don’t create duplicates when you seed data during development.

First, it will execute a query in your database looking for a record where whatever you supplied as a key (first parameter) matches the mapped column value (or values) supplied in the AddOrUpdate. So this is a little loosey-goosey for matching but perfectly fine for seeding design time data.

More importantly, if a match is found then the update will update all and null out any that weren’t in your AddOrUpdate.

That said, I have a situation where I am pulling data from an external service and inserting or updating existing values by primary key (and my local data for consumers is read-only) - been using AddOrUpdate in production for more than 6 months now and so far no problems.

So that you don't mess up other permissions already on the file, use the flag +, such as via

sudo chmod -R o+rw /var/www

I do recommend you to change the configuration of JDK used by NetBeans in netbeans.conf config file:

netbeans_jdkhome="C:\Program Files\Java\..."

This is an old question, but it is worth noting that you can now use setnames from the data.table package.

library(data.table)

setnames(DF, "oldName", "newName")

# or since the data.frame in question is just one column: 
setnames(DF, "newName")

# And for reference's sake, in general (more than once column)
nms <- c("col1.name", "col2.name", etc...)
setnames(DF, nms)

Looks like this behavior is how Ansible currently works, although there is a lot of interest in fixing it to work as desired. There's currently a pull request with the desired functionality so hopefully this will get incorporated into Ansible eventually.

java.util.Date temp = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSSSSS").parse("2012-07-10 14:58:00.000000");

The mm is minutes you want MM

CODE

public class Test {

    public static void main(String[] args) throws ParseException {
        java.util.Date temp = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSSSSS")
                .parse("2012-07-10 14:58:00.000000");
        System.out.println(temp);
    }
}

Prints:

Tue Jul 10 14:58:00 EDT 2012

do you like it

print(fr"\{''}")

or how about this

print(r"\ "[0])

You can set AWS_REGION environment.

assert(process.env.AWS_REGION, 'Missing AWS_REGION env (eg. ap-northeast-1)');
const aws = require('aws-sdk');
const lambda = new aws.Lambda();

It looks like your 'trainData' is a list of strings:

['-214' '-153' '-58' ..., '36' '191' '-37']

Change your 'trainData' to a numeric type.

 import numpy as np
 np.array(['1','2','3']).astype(np.float)

For me it was enough to reinstall whitelist plugin:

cordova plugin remove cordova-plugin-whitelist

and then

cordova plugin add cordova-plugin-whitelist

It looks like updating from previous versions of Cordova was not succesful.

Look at the API from hostip.info - it provides lots of information.
Example in PHP:

$data = file_get_contents("http://api.hostip.info/country.php?ip=12.215.42.19");
//$data contains: "US"

$data = file_get_contents("http://api.hostip.info/?ip=12.215.42.19");
//$data contains: XML with country, lat, long, city, etc...

If you trust hostip.info, it seems to be a very useful API.

See my answer in this thread.

intent.putExtra("Some string",very_large_obj_for_binder_buffer);

You are exceeding the binder transaction buffer by transferring large element(s) from one activity to another activity.

$result = mysqli_query($con,"SELECT `note` FROM `glogin_users` WHERE email = '".$email."'");
while($row = mysqli_fetch_array($result))
echo $row['note'];

Modified a bit code of @Dr.sai 's code. Hope this will be useful.

Hoping this will be helpful to hide some columns too. Link to file

Try this

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

Result will be

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

Assuming you're interested in whether the variable has been explicitly assigned a value or not, the answer is "not really". There's absolutely no difference between a field (instance variable or class variable) which hasn't been explicitly assigned at all yet, and one which has been assigned its default value - 0, false, null etc.

Now if you know that once assigned, the value will never reassigned a value of null, you can use:

if (box != null) {
    box.removeFromCanvas();
}

(and that also avoids a possible NullPointerException) but you need to be aware that "a field with a value of null" isn't the same as "a field which hasn't been explicitly assigned a value". Null is a perfectly valid variable value (for non-primitive variables, of course). Indeed, you may even want to change the above code to:

if (box != null) {
    box.removeFromCanvas();
    // Forget about the box - we don't want to try to remove it again
    box = null;
}

The difference is also visible for local variables, which can't be read before they've been "definitely assigned" - but one of the values which they can be definitely assigned is null (for reference type variables):

// Won't compile
String x;
System.out.println(x);

// Will compile, prints null
String y = null;
System.out.println(y);

This is very often a symptom of an antipattern. The tool which produced the line numbers may well be replaced with one which deletes the lines right away. For example;

grep -nh error logfile | cut -d: -f1 | deletelines logfile

(where deletelines is the utility you are imagining you need) is the same as

grep -v error logfile

Having said that, if you are in a situation where you genuinely need to perform this task, you can generate a simple sed script from the file of line numbers. Humorously (but perhaps slightly confusingly) you can do this with sed.

sed 's%$%d%' linenumbers

This accepts a file of line numbers, one per line, and produces, on standard output, the same line numbers with d appended after each. This is a valid sed script, which we can save to a file, or (on some platforms) pipe to another sed instance:

sed 's%$%d%' linenumbers | sed -f - logfile

On some platforms, sed -f does not understand the option argument - to mean standard input, so you have to redirect the script to a temporary file, and clean it up when you are done, or maybe replace the lone dash with /dev/stdin or /proc/$pid/fd/1 if your OS (or shell) has that.

As always, you can add -i before the -f option to have sed edit the target file in place, instead of producing the result on standard output. On *BSDish platforms (including OSX) you need to supply an explicit argument to -i as well; a common idiom is to supply an empty argument; -i ''.

Also worth mentioning, in C# the OR operator is short-circuiting. In your example, Close seems to be a property, but if it were a method, it's worth noting that:

if (ActionsLogWriter.Close() || ErrorDumpWriter.Close())

is fundamentally different from

if (ErrorDumpWriter.Close() || ActionsLogWriter.Close())

In C#, if the first expression returns true, the second expression will not be evaluated at all. Just be aware of this. It actually works to your advantage most of the time.

you can use simple if condition like:

if(round(var) != var)­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­

Here is the example from w3chools that was mentioned.

function setCookie(cname, cvalue, exdays) {
    var d = new Date();
    d.setTime(d.getTime() + (exdays*24*60*60*1000));
    var expires = "expires="+ d.toUTCString();
    document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
}

function getCookie(cname) {
    var name = cname + "=";
    var decodedCookie = decodeURIComponent(document.cookie);
    var ca = decodedCookie.split(';');
    for(var i = 0; i <ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') {
            c = c.substring(1);
        }
        if (c.indexOf(name) == 0) {
            return c.substring(name.length, c.length);
        }
    }
    return "";
}

Here's a simple little function that will rbind two datasets together after auto-detecting what columns are missing from each and adding them with all NAs.

For whatever reason this returns MUCH faster on larger datasets than using the merge function.

fastmerge <- function(d1, d2) {
  d1.names <- names(d1)
  d2.names <- names(d2)

  # columns in d1 but not in d2
  d2.add <- setdiff(d1.names, d2.names)

  # columns in d2 but not in d1
  d1.add <- setdiff(d2.names, d1.names)

  # add blank columns to d2
  if(length(d2.add) > 0) {
    for(i in 1:length(d2.add)) {
      d2[d2.add[i]] <- NA
    }
  }

  # add blank columns to d1
  if(length(d1.add) > 0) {
    for(i in 1:length(d1.add)) {
      d1[d1.add[i]] <- NA
    }
  }

  return(rbind(d1, d2))
}

The warning is due to you attempting to add an integer (int shift = 3) to a character value. You can change the data type to char if you want to avoid that.

A char is 16 bits, an int is 32.

char shift = 3;
// ...
eMessage[i] = (message[i] + shift) % (char)letters.length;

As an aside, you can simplify the following:

char[] message = {'o', 'n', 'c', 'e', 'u', 'p', 'o', 'n', 'a', 't', 'i', 'm', 'e'}; 

To:

char[] message = "onceuponatime".toCharArray();

sorted=($(echo ${array[@]} | tr " " "\n" | sort))

In the spirit of bash / linux, I would pipe the best command-line tool for each step. sort does the main job but needs input separated by newline instead of space, so the very simple pipeline above simply does:

Echo array content --> replace space by newline --> sort

$() is to echo the result

($()) is to put the "echoed result" in an array

Note: as @sorontar mentioned in a comment to a different question:

The sorted=($(...)) part is using the "split and glob" operator. You should turn glob off: set -f or set -o noglob or shopt -op noglob or an element of the array like * will be expanded to a list of files.

following Donald's comment:

This variable applies when binary logging is enabled.

All I had to do was:

1. disabled log_bin in my.cnf (#log_bin)
2. restart mysql
3. import DB
4. enable log_bin
5. restart mysql

That step out that import problem.

(Then I'll review the programmer's code to suggest an improvement)

The only reason I'd worry about is that Dog is now allocated on the stack, rather than the heap. So if Dog is megabytes in size, you may have a problem,

If you do need to go the new/delete route, be wary of exceptions. And because of this you should use auto_ptr or one of the boost smart pointer types to manage the object lifetime.

Not the place to give a complete tutorial, but here it is in short;

RewriteCond basically means "execute the next RewriteRule only if this is true". The !-l path is the condition that the request is not for a link (! means not, -l means link)

The RewriteRule basically means that if the request is done that matches ^(.+)$ (matches any URL except the server root), it will be rewritten as index.php?url=$1 which means a request for ollewill be rewritten as index.php?url=olle).

QSA means that if there's a query string passed with the original URL, it will be appended to the rewrite (olle?p=1 will be rewritten as index.php?url=olle&p=1.

L means if the rule matches, don't process any more RewriteRules below this one.

For more complete info on this, follow the links above. The rewrite support can be a bit hard to grasp, but there are quite a few examples on stackoverflow to learn from.

instanceof is used to check if an object is an instance of a class, an instance of a subclass, or an instance of a class that implements a particular interface.

I've used Code-based registration for provider. link1 link2

Just created the configuration class like

class DbContextConfiguration : DbConfiguration
{
    public DbContextConfiguration()
    {
        this.SetDatabaseInitializer(new DropCreateDatabaseAlways<MyDbContext>());
        this.SetProviderServices(SqlProviderServices.ProviderInvariantName, SqlProviderServices.Instance);
    }
}

Key point is this.SetProviderServices(SqlProviderServices.ProviderInvariantName, SqlProviderServices.Instance);

and used it in the such way

[DbConfigurationType(typeof(DbContextConfiguration))]
public class MyDbContext : DbContext
{
    public MyDbContext()
    {
        ...
    }

    public DbSet<...> ...{ get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        ...
    }
}

This works:

myElement.className = 'foo bar baz';

I have tried this, write your own code for formWindowClosing() event.

 private void formWindowClosing(java.awt.event.WindowEvent evt) {                                   
    int selectedOption = JOptionPane.showConfirmDialog(null,
            "Do you want to exit?",
            "FrameToClose",
            JOptionPane.YES_NO_OPTION);
    if (selectedOption == JOptionPane.YES_OPTION) {
        setVisible(false);
        dispose();
    } else {
        setDefaultCloseOperation(javax.swing.WindowConstants.DO_NOTHING_ON_CLOSE);
    }
}    

This asks user whether he want to exit the Frame or Application.

The withColumn function in pyspark enables you to make a new variable with conditions, add in the when and otherwise functions and you have a properly working if then else structure. For all of this you would need to import the sparksql functions, as you will see that the following bit of code will not work without the col() function. In the first bit, we declare a new column -'new column', and then give the condition enclosed in when function (i.e. fruit1==fruit2) then give 1 if the condition is true, if untrue the control goes to the otherwise which then takes care of the second condition (fruit1 or fruit2 is Null) with the isNull() function and if true 3 is returned and if false, the otherwise is checked again giving 0 as the answer.

from pyspark.sql import functions as F
df=df.withColumn('new_column', 
    F.when(F.col('fruit1')==F.col('fruit2'), 1)
    .otherwise(F.when((F.col('fruit1').isNull()) | (F.col('fruit2').isNull()), 3))
    .otherwise(0))

The best way is to use an And clause in your While statement

Dim count as Integer
count =0
While True And count <= 10
    count=count+1
    Debug.Print(count)
Wend

You want to put the ISNULL inside of the COUNT function, not outside:

Not GOOD: ISNULL(COUNT(field), 0)

GOOD: COUNT(ISNULL(field, 0))

Even you don't need to run the loop for that.

You can delete all the node_modules by using the only single command:-

For prototyping, using curl from the shell with the -m parameter allow to pass milliseconds, and will work in both cases, either the connection didn't initiate, error 404, 500, bad url, or the whole data wasn't retrieved in full in the allowed time range, the timeout is always effective. Php won't ever hang out.

Simply don't pass unsanitized user data in the shell call.

system("curl -m 50 -X GET 'https://api.kraken.com/0/public/OHLC?pair=LTCUSDT&interval=60' -H  'accept: application/json' > data.json");
// This data had been refreshed in less than 50ms
var_dump(json_decode(file_get_contents("data.json"),true));

I resolved the issue via this command

pg_ctl -D /usr/local/var/postgres start

At times, you might get this error

SELECT trim(COLUMN_VALUE) str FROM xmltable(('"'||REPLACE('a1, b2, a2, c1', ',', '","')||'"'));

to RelativeLayout, try this code , it works for me: yourLayoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);

Wrap your dialog_custom_layout.xml into RelativeLayout instead of any other layout.That worked for me.

Vector is a template class and it is not safe to convert the contents of a class to a pointer : You cannot inherit the vector class to add this new functionality. and changing the function parameter is actually a better idea. Jst create another vector of int vector temp_foo (foo.begin[X],foo.end()); and pass this vector to you functions

You have to use the SSH version, not HTTPS. When you clone from a repository, copy the link with the SSH version, because SSH is easy to use and solves all problems with access. You can set the access for every SSH you input into your account (like push, pull, clone, etc...)

Here is a link, which says why we need SSH and how to use it: step by step

I believe the way to do this is $location.url('/RouteTo/Login');

Edit for Clarity

Say my route for my login view was /Login, I would say $location.url('/Login') to navigate to that route.

For locations outside of the Angular app (i.e. no route defined), plain old JavaScript will serve:

window.location = "http://www.my-domain.com/login"

When you use the -m option putty does not allocate a tty, it runs the command and quits. If you want to run an interactive script (such as a sql client), you need to tell it to allocate a tty with -t, see 3.8.3.12 -t and -T: control pseudo-terminal allocation. You'll avoid keeping a script on the server, as well as having to invoke it once you're connected.

I come back to this answer fairly often, though none of these are quite right for me. That said, the right answer for me is a mixture of the others.

What I find works is the following:

 git config --global core.eol lf
 git config --global core.autocrlf input

For repos that were checked out after those global settings were set, everything will be checked out as whatever it is in the repo – hopefully LF (\n). Any CRLF will be converted to just LF on checkin.

With an existing repo that you have already checked out – that has the correct line endings in the repo but not your working copy – you can run the following commands to fix it:

git rm -rf --cached .
git reset --hard HEAD

This will delete (rm) recursively (r) without prompt (-f), all files except those that you have edited (--cached), from the current directory (.). The reset then returns all of those files to a state where they have their true line endings (matching what's in the repo).

If you need to fix the line endings of files in a repo, I recommend grabbing an editor that will let you do that in bulk like IntelliJ or Sublime Text, but I'm sure any good one will likely support this.

I added a HorizontalAlignment="Center" (The default is "Strech") and it solved my problem because it made the datagrid only as wide as needed. (Removed the datagrid's Width setting if you have one.)

Just want to add another solution for React Native users that just need the Expo app.

1. Install the Expo app
2. Open you project
3. Click Device -> Open on Android - In this stage Expo will install the expo android app and you'll be able to open it.

Yeah, for safety I would probably do:

if(array == null || array.Length == 0)

In your while statement just replace mysql_fetch_row with mysql_fetch_array or mysql_fetch_assoc... whichever works...

You can get its address by using:

document.getElementById('myframe').src

Not sure if I understood your question correctly but anyways :)

I had the same problem, when i loaded a text file via fs.readFile(), I tried to set the encodeing to UTF8, it keeped the same. my solution now is this:

myString = JSON.parse( JSON.stringify( myString ) )

after this an Ö is realy interpreted as an Ö.

I was also facing same problem on Amazon windows EC2 instance ( Windows Server 2012 R2 ) Then I figured out , it was local windows firewall preventing it . I opened port 80 ( defined port for website ) using windows Firewall with Advance Security .

It resolved the issue .

The following program calculates nCr in an efficient manner (compared to calculating factorials etc.)

import operator as op
from functools import reduce

def ncr(n, r):
    r = min(r, n-r)
    numer = reduce(op.mul, range(n, n-r, -1), 1)
    denom = reduce(op.mul, range(1, r+1), 1)
    return numer // denom  # or / in Python 2

As of Python 3.8, binomial coefficients are available in the standard library as math.comb:

>>> from math import comb
>>> comb(10,3)
120

If it helps you can embed a tab character in a double quoted string:

PS> "`t hello"

You can to this in Twig or the FormClass as shown in the examples above. But you might want to decide in the controller which class your form should get. Just keep in mind to not have much logic in the controller in general!

    $form = $this->createForm(ContactForm::class, null, [
        'attr' => [
            'class' => 'my_contact_form'
        ]
    ]);

In ECMA2016 you can use the includes method. It's the cleanest way I've seen. (Supported by all major browsers)

if([1,3,12].includes(foo)) {
    // ...
}

The 500 (internal server error) means something went wrong on the server's side. It could be several things, but I would start by verifying that the URL and parameters are correct. Also, make sure that whatever handles the request is expecting the request as a GET and not a POST.

One useful way to learn more about what's going on is to use a tool like Fiddler which will let you watch all HTTP requests and responses so you can see exactly what you're sending and the server is responding with.

If you don't have a compelling reason to write your own Ajax code, you would be far better off using a library that handles the Ajax interactions for you. jQuery is one option.

On most Linux systems, simply typing whoami on the command line provides the user ID.

However, on Solaris, you may have to determine the user ID, by determining the UID of the user logged-in through the command below.

echo $UID

Once the UID is known, find the user by matching the UID against the /etc/passwd file.

cat /etc/passwd | cut -d":" -f1,3

This is the only answer that is type safe

E[] a;

a = newArray(size);

@SafeVarargs

{
    return Arrays.copyOf(array, length);
}

I had to manually uninstall all instances of the .dll from the registry, and all instances of the .dll from my local drive. Uninstalled/reinstalled my app and now im hitting breakpoints! Wasted a half a day doing this :(.

Here is how I do it:

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import java.io.File;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;



public class MainFrame implements ActionListener{

/**

 */


/**
 * @param args
 */
public static void main(String[] args) {
    String appdata = System.getenv("APPDATA");
    String iconPath = appdata + "\\JAPP_icon.png";
    File icon = new File(iconPath);

    if(!icon.exists()){
        FileDownloaderNEW fd = new FileDownloaderNEW();
        fd.download("http://icons.iconarchive.com/icons/artua/mac/512/Setting-icon.png", iconPath, false, false);
    }
        JFrame frm = new JFrame("Test");
        ImageIcon imgicon = new ImageIcon(iconPath);
        JButton bttn = new JButton("Kill");
        MainFrame frame = new MainFrame();
        bttn.addActionListener(frame);
        frm.add(bttn);
        frm.setIconImage(imgicon.getImage());
        frm.setSize(100, 100);
        frm.setVisible(true);


}

For me the dialogue appears more than one if I click the dpFlightDate edit text more than one time same for the timmer dialog . how can I avoid this dialog to appear only once and if the user click's 2nd time the dialog must not appear again ie if dialog is on the screen ?

          // perform click event on edit text
            dpFlightDate.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    // calender class's instance and get current date , month and year from calender
                    final Calendar c = Calendar.getInstance();
                    int mYear = c.get(Calendar.YEAR); // current year
                    int mMonth = c.get(Calendar.MONTH); // current month
                    int mDay = c.get(Calendar.DAY_OF_MONTH); // current day
                    // date picker dialog
                    datePickerDialog = new DatePickerDialog(frmFlightDetails.this,
                            new DatePickerDialog.OnDateSetListener() {
                                @Override
                                public void onDateSet(DatePicker view, int year,
                                                      int monthOfYear, int dayOfMonth) {
                                    // set day of month , month and year value in the edit text
                                    dpFlightDate.setText(dayOfMonth + "/"
                                            + (monthOfYear + 1) + "/" + year);

                                }
                            }, mYear, mMonth, mDay);
                    datePickerDialog.show();
                }
            });
            tpFlightTime.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    // Use the current time as the default values for the picker
                    final Calendar c = Calendar.getInstance();
                    int hour = c.get(Calendar.HOUR_OF_DAY);
                    int minute = c.get(Calendar.MINUTE);
                    // Create a new instance of TimePickerDialog
                    timePickerDialog = new TimePickerDialog(frmFlightDetails.this, new TimePickerDialog.OnTimeSetListener() {
                        @Override
                        public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
                            tpFlightTime.setText( selectedHour + ":" + selectedMinute);
                        }
                    }, hour, minute, true);//Yes 24 hour time
                    timePickerDialog.setTitle("Select Time");
                    timePickerDialog.show();
                }
            });

If you are on a system where netstat is not available (e.g. RHEL 7 and more recent Debian releases) you can use ss, as below:

sudo ss -tlpn | grep mysql

And you'll get something like the following for output:

LISTEN     0      50        *:3306        *:*        users:(("mysqld",pid=5307,fd=14))

The fourth column is Local Address:Port. So in this case Mysql is listening on port 3306, the default.

try this one :),

Get-LocalGroup | %{ $groups = "$(Get-LocalGroupMember -Group $_.Name | %{ $_.Name } | Out-String)"; Write-Output "$($_.Name)>`r`n$($groups)`r`n" }

In my case 'await' never finished because of exception while executing the request, e.g. server not responding, etc. Surround it with try..catch to identify what happened, it'll also complete your 'await' gracefully.

public async Task<Stuff> GetStuff(string id)
{
    string path = $"/api/v2/stuff/{id}";
    try
    {
        HttpResponseMessage response = await client.GetAsync(path);
        if (response.StatusCode == HttpStatusCode.OK)
        {
            string json = await response.Content.ReadAsStringAsync();
            return JsonUtility.FromJson<Stuff>(json);
        }
        else
        {
            Debug.LogError($"Could not retrieve stuff {id}");
        }
    }
    catch (Exception exception)
    {
        Debug.LogError($"Exception when retrieving stuff {exception}");
    }
    return null;
}

Here is my code:

The second placeholder is for decimals.

The last placeholder is for thousands separator.

Also you should note that if your project is consist of several modules which are dependent on each other, you should use "install" instead of "package", otherwise your build will fail, cause when you use install command, module A will be packaged and deployed to local repository and then if module B needs module A as a dependency, it can access it from local repository.

You can use canvas’ context.translate & context.rotate to do rotate your image

Here’s a function to draw an image that is rotated by the specified degrees:

function drawRotated(degrees){
    context.clearRect(0,0,canvas.width,canvas.height);

    // save the unrotated context of the canvas so we can restore it later
    // the alternative is to untranslate & unrotate after drawing
    context.save();

    // move to the center of the canvas
    context.translate(canvas.width/2,canvas.height/2);

    // rotate the canvas to the specified degrees
    context.rotate(degrees*Math.PI/180);

    // draw the image
    // since the context is rotated, the image will be rotated also
    context.drawImage(image,-image.width/2,-image.width/2);

    // we’re done with the rotating so restore the unrotated context
    context.restore();
}

The ngRoute module is no longer part of the core angular.js file. If you are continuing to use $routeProvider then you will now need to include angular-route.js in your HTML:

<script src="angular.js">
<script src="angular-route.js">

API Reference

You also have to add ngRoute as a dependency for your application:

var app = angular.module('MyApp', ['ngRoute', ...]);

If instead you are planning on using angular-ui-router or the like then just remove the $routeProvider dependency from your module .config() and substitute it with the relevant provider of choice (e.g. $stateProvider). You would then use the ui.router dependency:

var app = angular.module('MyApp', ['ui.router', ...]);

Hope this helps

string myString = "abc";
double num;
bool isNumber = double.TryParse(myString , out num);

I was wondering how to do this myself; it seems Gmail has since silently implemented this feature. I created the following filter:

Matches: subject:([test])
Do this: Skip Inbox

And then I sent a message with the subject

[test] foo

And the message was archived! So it seems all that is necessary is to create a filter for the subject prefix you wish to handle.

Less efficient, but simpler-looking:

m0 = re.match("I love (\w+)", statement)
m1 = re.match("Ich liebe (\w+)", statement)
m2 = re.match("Je t'aime (\w+)", statement)
if m0:
  print "He loves",m0.group(1)
elif m1:
  print "Er liebt",m1.group(1)
elif m2:
  print "Il aime",m2.group(1)

The problem with the Perl stuff is the implicit updating of some hidden variable. That's simply hard to achieve in Python because you need to have an assignment statement to actually update any variables.

The version with less repetition (and better efficiency) is this:

pats = [
    ("I love (\w+)", "He Loves {0}" ),
    ("Ich liebe (\w+)", "Er Liebe {0}" ),
    ("Je t'aime (\w+)", "Il aime {0}")
 ]
for p1, p3 in pats:
    m= re.match( p1, statement )
    if m:
        print p3.format( m.group(1) )
        break

A minor variation that some Perl folk prefer:

pats = {
    "I love (\w+)" : "He Loves {0}",
    "Ich liebe (\w+)" : "Er Liebe {0}",
    "Je t'aime (\w+)" : "Il aime {0}",
}
for p1 in pats:
    m= re.match( p1, statement )
    if m:
        print pats[p1].format( m.group(1) )
        break

This is hardly worth mentioning except it does come up sometimes from Perl programmers.

i used this code and it works fine for me, just change +92xxxxxxxxxx to your valid whatsapp number, with country code

<script type="text/javascript">
        (function () {
            var options = {
                whatsapp: "+92xxxxxxxxxx", // WhatsApp number
                call_to_action: "Message us", // Call to action
                position: "right", // Position may be 'right' or 'left'

            };
            var proto = document.location.protocol, host = "whatshelp.io", url = proto + "//static." + host;
            var s = document.createElement('script'); s.type = 'text/javascript'; s.async = true; s.src = url + '/widget-send-button/js/init.js';
            s.onload = function () { WhWidgetSendButton.init(host, proto, options); };
            var x = document.getElementsByTagName('script')[0]; x.parentNode.insertBefore(s, x);
        })();

in my case, this error is raised due to sequence was not created..

It's not only a Python bug with * actually, it can also happen when you pass a string as a part of your regular expression to be compiled, like ;

import re
input_line = "string from any input source"
processed_line= "text to be edited with {}".format(input_line)
target = "text to be searched"
re.search(processed_line, target)

this will cause an error if processed line contained some "(+)" for example, like you can find in chemical formulae, or such chains of characters. the solution is to escape but when you do it on the fly, it can happen that you fail to do it properly...

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

For deleting, it is best to use this.$delete(array, index) for reactive objects.

Vue.delete( target, key ): Delete a property on an object. If the object is reactive, ensure the deletion triggers view updates. This is primarily used to get around the limitation that Vue cannot detect property deletions, but you should rarely need to use it.

In my case it was a package name conflict. Current project and signed referenced library had one package in common package.foo.utils. Just changed the current project error-prone package name to something else.

The above is same as using indexers in c#.

The conceptual differences between NULL and "empty-string" are real and very important in database design, but often misunderstood and improperly applied - here's a short description of the two:

NULL - means that we do NOT know what the value is, it may exist, but it may not exist, we just don't know.

Empty-String - means we know what the value is and that it is nothing.

Here's a simple example: Suppose you have a table with people's names including separate columns for first_name, middle_name, and last_name. In the scenario where first_name = 'John', last_name = 'Doe', and middle_name IS NULL, it means that we do not know what the middle name is, or if it even exists. Change that scenario such that middle_name = '' (i.e. empty-string), and it now means that we know that there is no middle name.

I once heard a SQL Server instructor promote making every character type column in a database required, and then assigning a DEFAULT VALUE to each of either '' (empty-string), or 'unknown'. In stating this, the instructor demonstrated he did not have a clear understanding of the difference between NULLs and empty-strings. Admittedly, the differences can seem confusing, but for me the above example helps to clarify the difference. Also, it is important to understand the difference when writing SQL code, and properly handle for NULLs as well as empty-strings.

One more reason for the error.

if you are exporting after wrapping component with connect()() then props may give typescript error
Solution: I didn't explore much as I had the option of replacing connect function with useSelector hook
for example

/* Comp.tsx */
interface IComp {
 a: number
}

const Comp = ({a}:IComp) => <div>{a}</div>

/* ** 

below line is culprit, you are exporting default the return 
value of Connect and there is no types added to that return
value of that connect()(Comp) 

** */

export default connect()(Comp)


--
/* App.tsx */
const App = () => {
/**  below line gives same error 
[ts] Argument of type 'number' is not assignable to 
parameter of type 'never' */
 return <Comp a={3} />
}

I'd recommend looking at consistent gets/logical reads as a better proxy for 'work' than run time. The run time can be skewed by what else is happening on the database server, how much stuff is in the cache etc.

But if you REALLY want SQL executing time, the V$SQL view has both CPU_TIME and ELAPSED_TIME.

To help make life easier, as my file editor(s) do not natively handle this, I made a couple of simple scripts for laptop/desktop editing work, share here in case they are any use to any one else. I have stuck with php as it is handling these things directly and very well.

Under Windows 8.1 say---

C:\Users\`your user name`\AppData\Roaming\Microsoft\Windows\SendTo

... there as an Administrator you can establish a shortcut to a batch file in your path. That batch file will call a php (cli) script.

You can then right click an image in file explorer, and SendTo the batchfile.

Ok Admiinstartor request, and wait for the black command shell windows to close.

Then just simply paste the result from clipboard in your into your text editor...

<img src="|">

or

 `background-image : url("|")` 

Following should be adaptable for other OS.

Batch file...

rem @echo 0ff
rem Puts 64 encoded version of a file on clipboard
php c:\utils\php\make64Encode.php %1

And with php.exe in your path, that calls a php (cli) script...

<?php 

function putClipboard($text){
 // Windows 8.1 workaround ...

  file_put_contents("output.txt", $text);

  exec("  clip < output.txt");

}


// somewhat based on http://perishablepress.com/php-encode-decode-data-urls/
// convert image to dataURL

$img_source = $argv[1]; // image path/name
$img_binary = fread(fopen($img_source, "r"), filesize($img_source));
$img_string = base64_encode($img_binary);

$finfo = finfo_open(FILEINFO_MIME_TYPE); 
$dataType = finfo_file($finfo, $img_source); 


$build = "data:" . $dataType . ";base64," . $img_string;

Depends on your specific situation, but if the iframe can be deployed after the rest of the page's loading, you can simply use a query string, a la:

And then somewhere in some_page.html:

<script>
var params = location.href.split('?')[1].split('&');
data = {};
for (x in params)
 {
data[params[x].split('=')[0]] = params[x].split('=')[1];
 }
</script>

Classic mode (the only mode in IIS6 and below) is a mode where IIS only works with ISAPI extensions and ISAPI filters directly. In fact, in this mode, ASP.NET is just an ISAPI extension (aspnet_isapi.dll) and an ISAPI filter (aspnet_filter.dll). IIS just treats ASP.NET as an external plugin implemented in ISAPI and works with it like a black box (and only when it's needs to give out the request to ASP.NET). In this mode, ASP.NET is not much different from PHP or other technologies for IIS.

Integrated mode, on the other hand, is a new mode in IIS7 where IIS pipeline is tightly integrated (i.e. is just the same) as ASP.NET request pipeline. ASP.NET can see every request it wants to and manipulate things along the way. ASP.NET is no longer treated as an external plugin. It's completely blended and integrated in IIS. In this mode, ASP.NET HttpModules basically have nearly as much power as an ISAPI filter would have had and ASP.NET HttpHandlers can have nearly equivalent capability as an ISAPI extension could have. In this mode, ASP.NET is basically a part of IIS.

If you have devtools like auto build dependency remove it. It is automatically build your project and run it. When you build manually it show port in use.

The general answer to this question is:

Don't geocode known locations every time you load your page. Geocode them off-line and use the resulting coordinates to display the markers on your page.

The limits exist for a reason.

If you can't geocode the locations off-line, see this page (Part 17 Geocoding multiple addresses) from Mike Williams' v2 tutorial which describes an approach, port that to the v3 API.

@VonC's answer to a duplicate question:

If, as commented, Paraminko does not support PPK key, the official solution, as seen here, would be to use PuTTYgen.

But you can also use the Python library CkSshKey to make that same conversion directly in your program.

See "Convert PuTTY Private Key (ppk) to OpenSSH (pem)"

import sys
import chilkat

key = chilkat.CkSshKey()

#  Load an unencrypted or encrypted PuTTY private key.

#  If  your PuTTY private key is encrypted, set the Password
#  property before calling FromPuttyPrivateKey.
#  If your PuTTY private key is not encrypted, it makes no diffference
#  if Password is set or not set.
key.put_Password("secret")

#  First load the .ppk file into a string:

keyStr = key.loadText("putty_private_key.ppk")

#  Import into the SSH key object:
success = key.FromPuttyPrivateKey(keyStr)
if (success != True):
    print(key.lastErrorText())
    sys.exit()

#  Convert to an encrypted or unencrypted OpenSSH key.

#  First demonstrate converting to an unencrypted OpenSSH key

bEncrypt = False
unencryptedKeyStr = key.toOpenSshPrivateKey(bEncrypt)
success = key.SaveText(unencryptedKeyStr,"unencrypted_openssh.pem")
if (success != True):
    print(key.lastErrorText())
    sys.exit()

put it in between <pre></pre> tags then use this characters

Syntax of waitpid():

pid_t waitpid(pid_t pid, int *status, int options);

The value of pid can be:

• < -1: Wait for any child process whose process group ID is equal to the absolute value of pid.
• -1: Wait for any child process.
• 0: Wait for any child process whose process group ID is equal to that of the calling process.
• > 0: Wait for the child whose process ID is equal to the value of pid.

The value of options is an OR of zero or more of the following constants:

• WNOHANG: Return immediately if no child has exited.
• WUNTRACED: Also return if a child has stopped. Status for traced children which have stopped is provided even if this option is not specified.
• WCONTINUED: Also return if a stopped child has been resumed by delivery of SIGCONT.

For more help, use man waitpid.

It will be cleaner if you encode your data to JSON, then send it to Node.js.

function (req, res) {
    if (req.method == 'POST') {
        var jsonString = '';

        req.on('data', function (data) {
            jsonString += data;
        });

        req.on('end', function () {
            console.log(JSON.parse(jsonString));
        });
    }
}

It seems that your project is written in Python < 3. This is because the file() builtin function is removed in Python 3. Try using Python 2to3 tool or edit the erroneous file yourself.

If you have Task constructor, then we may extract Thread from the Task, and invoke thread.abort.

Thread th = null;

Task.Factory.StartNew(() =>

    {
        Console.WriteLine(DateTime.UtcNow);

Looks to me like you are not dealing properly with your Initialization Vector (IV). It's been a long time since I last read about AES, IVs and block chaining, but your line

IvParameterSpec ivParameterSpec = new IvParameterSpec(aesKey.getEncoded());

does not seem to be OK. In the case of AES, you can think of the initialization vector as the "initial state" of a cipher instance, and this state is a bit of information that you can not get from your key but from the actual computation of the encrypting cipher. (One could argue that if the IV could be extracted from the key, then it would be of no use, as the key is already given to the cipher instance during its init phase).

Therefore, you should get the IV as a byte[] from the cipher instance at the end of your encryption

  cipherOutputStream.close();
  byte[] iv = encryptCipher.getIV();

and you should initialize your Cipher in DECRYPT_MODE with this byte[] :

  IvParameterSpec ivParameterSpec = new IvParameterSpec(iv);

Then, your decryption should be OK. Hope this helps.

you forgot to add add alpha1 in module area

compile 'com.android.support:appcompat-v7:26.0.0-alpha1'

use maven repository in project area that's it

        maven {

        }
    }
}

The snippet you're showing doesn't seem to be directly responsible for the error.

This is how you can CAUSE the error:

namespace MyNameSpace
{
   int i; <-- THIS NEEDS TO BE INSIDE THE CLASS

   class MyClass
   {
      ...
   }
}

If you don't immediately see what is "outside" the class, this may be due to misplaced or extra closing bracket(s) }.

You just need to provide an alias for your aggregate columns in the CTE

d as (SELECT 
   duration, 
   sum(totalitems) as sumtotalitems
FROM 
   [DrySoftBranch].[dbo].[mnthItemWiseTotalQty] ('1') AS BkdQty
group by duration
)

I think "works fine in Firefox" is in the Quirks mode rendering only. In the Standard mode rendering, that might not work fine in Firefox too.

percentage depends on "containing block", instead of viewport.

CSS Specification says

The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the value computes to 'auto'.

so

#container { height: auto; }
#container #mainContentsWrapper { height: n%; }
#container #sidebarWrapper { height: n%; }

means

#container { height: auto; }
#container #mainContentsWrapper { height: auto; }
#container #sidebarWrapper { height: auto; }

To stretch to 100% height of viewport, you need to specify the height of the containing block (in this case, it's #container). Moreover, you also need to specify the height to body and html, because initial Containing Block is "UA-dependent".

All you need is...

html, body { height:100%; }
#container { height:100%; }

Since the jar file 'executes' then it contains compiled java files known as .class files. You cannot import it to eclipse and modify the code. You should ask the supplier of the "demo" for the "source code". (or check the page you got the demo from for the source code)

Unless, you want to decompile the .class files and import to Eclipse. That may not be the case for starters.

This is an answer based on jluckyiv's, but I think it is better and simpler to change Javascript as follows.

You should use urllib.reuqest, not urllib3.

import numpy as np    
hist, bin_edges = np.histogram([1, 1, 2, 2, 2, 2, 3], bins = range(5))

Below, hist indicates that there are 0 items in bin #0, 2 in bin #1, 4 in bin #3, 1 in bin #4.

print(hist)
# array([0, 2, 4, 1])   

bin_edges indicates that bin #0 is the interval [0,1), bin #1 is [1,2), ..., bin #3 is [3,4).

print (bin_edges)
# array([0, 1, 2, 3, 4]))  

Play with the above code, change the input to np.histogram and see how it works.

But a picture is worth a thousand words:

import matplotlib.pyplot as plt
plt.bar(bin_edges[:-1], hist, width = 1)
plt.xlim(min(bin_edges), max(bin_edges))

The clean way is to write your own directive to bind to "change" event. Just to let you know IE9 does not support FormData so you cannot really get the file object from the change event.

You can use ng-file-upload library which already supports IE with FileAPI polyfill and simplify the posting the file to the server. It uses a directive to achieve this.

<script src="angular.min.js"></script>
<script src="ng-file-upload.js"></script>

<div ng-controller="MyCtrl">
  <input type="file" ngf-select="onFileSelect($files)" multiple>
</div>

JS:

//inject angular file upload directive.
angular.module('myApp', ['ngFileUpload']);

var MyCtrl = [ '$scope', 'Upload', function($scope, Upload) {
  $scope.onFileSelect = function($files) {
    //$files: an array of files selected, each file has name, size, and type.
    for (var i = 0; i < $files.length; i++) {
      var $file = $files[i];
      Upload.upload({
        url: 'my/upload/url',
        data: {file: $file}
      }).then(function(data, status, headers, config) {
        // file is uploaded successfully
        console.log(data);
      }); 
    }
  }
}];

You need slightly different error handling for powershell functions and for calling exe's, and you need to be sure to tell the caller of your script that it has failed. Building on top of Exec from the library Psake, a script that has the structure below will stop on all errors, and is usable as a base template for most scripts.

Set-StrictMode -Version latest
$ErrorActionPreference = "Stop"


# Taken from psake https://github.com/psake/psake
<#
.SYNOPSIS
  This is a helper function that runs a scriptblock and checks the PS variable $lastexitcode
  to see if an error occcured. If an error is detected then an exception is thrown.
  This function allows you to run command-line programs without having to
  explicitly check the $lastexitcode variable.
.EXAMPLE
  exec { svn info $repository_trunk } "Error executing SVN. Please verify SVN command-line client is installed"
#>
function Exec
{
    [CmdletBinding()]
    param(
        [Parameter(Position=0,Mandatory=1)][scriptblock]$cmd,
        [Parameter(Position=1,Mandatory=0)][string]$errorMessage = ("Error executing command {0}" -f $cmd)
    )
    & $cmd
    if ($lastexitcode -ne 0) {
        throw ("Exec: " + $errorMessage)
    }
}

Try {

    # Put all your stuff inside here!

    # powershell functions called as normal and try..catch reports errors 
    New-Object System.Net.WebClient

    # call exe's and check their exit code using Exec
    Exec { setup.exe }

} Catch {
    # tell the caller it has all gone wrong
    $host.SetShouldExit(-1)
    throw
}

Commands

git fetch --all
git checkout -b <ur_new_local_branch_name> origin/<Remote_Branch_Name>

are equal to

 git fetch --all

and then

 git checkout -b fixes_for_dev origin/development

Both will create a latest fixes_for_dev from development

If you are using the Poco library, here is a portable way to delete a directory.

#include "Poco/File.h"
...
...
Poco::File fooDir("/path/to/your/dir");
fooDir.remove(true);

The remove function when called with "true" means recursively delete all files and sub directories in a directory.

I got the exactly same error, Do this instead:

npm install react-router@next 
react-router-dom@next
npm install --save history

Of course.

Declaring a class abstract only means that you don't allow it to be instantiated on its own.

Declaring a method abstract means that subclasses have to provide an implementation for that method.

The two are separate concepts, though obviously you can't have an abstract method in a non-abstract class. You can even have abstract classes with final methods but never the other way around.

Lets take a vector 'point' which has numbers from 1 to 5

point = c(1,2,3,4,5)

if we want to append a number 6 anywhere inside the vector then below command may come handy

i) Vectors

new_var = append(point, 6 ,after = length(point))

ii) columns of a table

new_var = append(point, 6 ,after = length(mtcars$mpg))

The command append takes three arguments:

1. the vector/column to be modified.
2. value to be included in the modified vector.
3. a subscript, after which the values are to be appended.

simple...!! Apologies in case of any...!

Here is a better way to loop over files as it handles spaces and newlines in file names:

#!/bin/bash

find . -type f -iname "*.txt" -print0 | while IFS= read -r -d $'\0' line; do
    echo "$line"
    ls -l "$line"    
done

You can use plain javascript, this will call your_func once, after 5 seconds:

setTimeout(function() { your_func(); }, 5000);

If your function has no parameters and no explicit receiver you can call directly setTimeout(func, 5000)

There is also a plugin I've used once. It has oneTime and everyTime methods.

• jQuery timers plugin

Run all Collection in a folder in parallel:

'use strict';

global.Promise = require('bluebird');
const path = require('path');
const newman =  Promise.promisifyAll(require('newman'));
const fs = Promise.promisifyAll(require('fs'));
const environment = 'postman_environment.json';
const FOLDER = path.join(__dirname, 'Collections_Folder');


let files = fs.readdirSync(FOLDER);
files = files.map(file=> path.join(FOLDER, file))
console.log(files);

Promise.map(files, file => {

    return newman.runAsync({
    collection: file, // your collection
    environment: path.join(__dirname, environment), //your env
    reporters: ['cli']
    });

}, {
   concurrency: 2
});

I do this frequently using Table Types to ensure more consistency and simplify code. You can't technically return "a table", but you can return a result set and using INSERT INTO .. EXEC ... syntax, you can clearly call a PROC and store the results into a table type. In the following example I'm actually passing a table into a PROC along with another param I need to add logic, then I'm effectively "returning a table" and can then work with that as a table variable.

/****** Check if my table type and/or proc exists and drop them ******/
IF EXISTS (SELECT * FROM sys.objects WHERE type = 'P' AND name = 'returnTableTypeData')
DROP PROCEDURE returnTableTypeData
GO
IF EXISTS (SELECT * FROM sys.types WHERE is_table_type = 1 AND name = 'myTableType')
DROP TYPE myTableType
GO

/****** Create the type that I'll pass into the proc and return from it ******/
CREATE TYPE [dbo].[myTableType] AS TABLE(
    [someInt] [int] NULL,
    [somenVarChar] [nvarchar](100) NULL
)
GO

CREATE PROC returnTableTypeData
    @someInputInt INT,
    @myInputTable myTableType READONLY --Must be readonly because
AS
BEGIN

    --Return the subset of data consistent with the type
    SELECT
        *
    FROM
        @myInputTable
    WHERE
        someInt < @someInputInt

END
GO


DECLARE @myInputTableOrig myTableType
DECLARE @myUpdatedTable myTableType

INSERT INTO @myInputTableOrig ( someInt,somenVarChar )
VALUES ( 0, N'Value 0' ), ( 1, N'Value 1' ), ( 2, N'Value 2' )

INSERT INTO @myUpdatedTable EXEC returnTableTypeData @someInputInt=1, @myInputTable=@myInputTableOrig

SELECT * FROM @myUpdatedTable


DROP PROCEDURE returnTableTypeData
GO
DROP TYPE myTableType
GO

As suggested in other answers it's probably easiest to "POST" the form data to the controller. If you need to pass an entire Model/Form you can easily do this with serialize() e.g.

$('#myform').on('submit', function(e){
    e.preventDefault();

    var formData = $(this).serialize();

    $.post('/student/update', formData, function(response){
         //Do something with response
    });
});

So your controller could have a view model as the param e.g.

 [HttpPost]
 public JsonResult Update(StudentViewModel studentViewModel)
 {}

Alternatively if you just want to post some specific values you can do:

$('#myform').on('submit', function(e){
    e.preventDefault();

    var studentId = $(this).find('#Student_StudentId');
    var isActive = $(this).find('#Student_IsActive');

    $.post('/my/url', {studentId : studentId, isActive : isActive}, function(response){
         //Do something with response
    });
});

With a controller like:

     [HttpPost]
     public JsonResult Update(int studentId, bool isActive)
     {}

You can do this with merge:

df_merged = df1.merge(df2, how='outer', left_index=True, right_index=True)

The keyword argument how='outer' keeps all indices from both frames, filling in missing indices with NaN. The left_index and right_index keyword arguments have the merge be done on the indices. If you get all NaN in a column after doing a merge, another troubleshooting step is to verify that your indices have the same dtypes.

The merge code above produces the following output for me:

                V1    V2
A 2012-01-01  12.0  15.0
  2012-02-01  14.0   NaN
  2012-03-01   NaN  21.0
B 2012-01-01  15.0  24.0
  2012-02-01   8.0   9.0
C 2012-01-01  17.0   NaN
  2012-02-01   9.0   NaN
D 2012-01-01   NaN   7.0
  2012-02-01   NaN  16.0

If the auditing is enabled on the server, just simply use

SELECT *
FROM ALL_TAB_MODIFICATIONS
WHERE TABLE_NAME IN ()

I experienced the same error in my Xamarin.Android solution.

I verified that my JSON was correct, and noticed that the error only appeared when I ran the app as a Release build.

It turned out that the Linker was removing a library from Newtonsoft.JSON, causing the JSON to be parsed incorrectly.

I fixed the error by adding Newtonsoft.Json to the Ignore assemblies setting in the Android Build Configuration (screen shot below)

JSON Parsing Code

static readonly JsonSerializer _serializer = new JsonSerializer();
static readonly HttpClient _client = new HttpClient();

static async Task<T> GetDataObjectFromAPI<T>(string apiUrl)
{
    using (var stream = await _client.GetStreamAsync(apiUrl).ConfigureAwait(false))
    using (var reader = new StreamReader(stream))
    using (var json = new JsonTextReader(reader))
    {
        if (json == null)
            return default(T);

        return _serializer.Deserialize<T>(json);
    }
}

You could also use float and inline-block to center your nav like the following:

nav li {
   float: left;
}
nav {
   display: inline-block;
}

Here's a modified version of SilentGhost's answer that will do what you want.

with open(fname, 'rb') as fh:
    first = next(fh)
    offs = -100
    while True:
        fh.seek(offs, 2)
        lines = fh.readlines()
        if len(lines)>1:
            last = lines[-1]
            break
        offs *= 2
    print first
    print last

No need for an upper bound for line length here.

I was getting the same UnicodeEncodeError when saving scraped web content to a file. To fix it I replaced this code:

with open(fname, "w") as f:
    f.write(html)

with this:

import io
with io.open(fname, "w", encoding="utf-8") as f:
    f.write(html)

Using io gives you backward compatibility with Python 2.

If you only need to support Python 3 you can use the builtin open function instead:

with open(fname, "w", encoding="utf-8") as f:
    f.write(html)

numpy.random.randint accepts a third argument (size) , in which you can specify the size of the output array. You can use this to create your DataFrame -

df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))

Here - np.random.randint(0,100,size=(100, 4)) - creates an output array of size (100,4) with random integer elements between [0,100) .

Demo -

import numpy as np
import pandas as pd
df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))

which produces:

     A   B   C   D
0   45  88  44  92
1   62  34   2  86
2   85  65  11  31
3   74  43  42  56
4   90  38  34  93
5    0  94  45  10
6   58  23  23  60
..  ..  ..  ..  ..

onclick = "setTimeout(function() { document.getElementById('div1').style.display='none';document.getElementById('div2').style.display='none'}, 1000)"

Change 1000 to the number of milliseconds you want to delay.

Simple solution that hasn't been mentioned on this question: restart your computer after you declare the path variable.

I always have to restart - the path never updates until I do. And when I do restart, the path always is updated.

After much searching a way to show a progress bar just to make the most elegant charging could not find any way that would serve my purpose. Check the actual status of the request showed demaziado complex and sometimes snippets not then worked created a very simple way but it gives me the experience seeking (or almost), follows the code:

$.ajax({
    type : 'GET',
    url : url,
    dataType: 'html',
    timeout: 10000,
    beforeSend: function(){
        $('.my-box').html('<div class="progress"><div class="progress-bar progress-bar-success progress-bar-striped active" role="progressbar" aria-valuenow="40" aria-valuemin="0" aria-valuemax="100" style="width: 0%;"></div></div>');
        $('.progress-bar').animate({width: "30%"}, 100);
    },
    success: function(data){  
        if(data == 'Unauthorized.'){
            location.href = 'logout';
        }else{
            $('.progress-bar').animate({width: "100%"}, 100);
            setTimeout(function(){
                $('.progress-bar').css({width: "100%"});
                setTimeout(function(){
                    $('.my-box').html(data);
                }, 100);
            }, 500);
        }
    },
    error: function(request, status, err) {
        alert((status == "timeout") ? "Timeout" : "error: " + request + status + err);
    }
});

Display white space characters

Menu: You can toggle the visibility of the white space characters from the menu: Edit > Advanced > View White Space.

Button: If you want to add the button to a toolbar, it is called Toggle Visual Space in the command category "Edit".
The actual command name is: Edit.ViewWhiteSpace.

Keyboard Shortcut: In Visual Studio 2015, 2017 and 2019 the default keyboard shortcut still is CTRL+R, CTRL+W
Type one after the other.
All default shortcuts

End-of-line characters

Extension: There is a minimal extension adding the displaying of end-of-line characters (LF and CR) to the visual white space mode, as you would expect. Additionally it supplies buttons and short-cuts to modify all line-endings in a document, or a selection.
VisualStudio gallery: End of the Line

Note: Since Visual Studio 2017 there is no option in the File-menu called Advanced Save Options. Changing the encoding and line-endings for a file can be done using Save File As ... and clicking the down-arrow on the right side of the save-button. This shows the option Save with Encoding. You'll be asked permission to overwrite the current file.

The answer I got is that variables and subqueries will not work and we have to user dynamic SQL script. The following works:

DECLARE @SQL VARCHAR(4000)
SET @SQL = 'ALTER TABLE dbo.Student DROP CONSTRAINT |ConstraintName| '

SET @SQL = REPLACE(@SQL, '|ConstraintName|', ( SELECT   name
                                               FROM     sysobjects
                                               WHERE    xtype = 'PK'
                                                        AND parent_obj =        OBJECT_ID('Student')))

EXEC (@SQL)

Individual element copy, it seems to work for me with just a simple example.

maps := map[string]int {
    "alice":12,
    "jimmy":15,
}

maps2 := make(map[string]int)
for k2,v2 := range maps {
    maps2[k2] = v2
}

maps2["miki"]=rand.Intn(100)

fmt.Println("maps: ",maps," vs. ","maps2: ",maps2)

You should use keyPressed if you want an immediate effect, and keyReleased if you want the effect after you release the key. You cannot use keyTyped because F5 is not a character. keyTyped is activated only when an character is pressed.

you can use decoration like this :

   Container(
                    width: 60,
                    height: 60,
                    child: Icon(CustomIcons.option, size: 20,),
                    decoration: BoxDecoration(
                        shape: BoxShape.circle,
                        color: Color(0xFFe0f2f1)),
                  )

Now you have circle shape and Icon on it.

int count = 100;
int total = 0;
int[] numbers = new int[count];
for (int i=0; count>i; i++) {
    numbers[i] = i+1;
    total += i+1;
}
// done

Slightly more compact:

df = pd.DataFrame([1, 2, 3, 4, 5], index=[100, 29, 234, 1, 150], columns=['A'])
df = df.sort_index()
print(df)

Note:

• sort has been deprecated, replaced by sort_index for this scenario
• preferable not to use inplace as it is usually harder to read and prevents chaining. See explanation in answer here: Pandas: peculiar performance drop for inplace rename after dropna

You need to implement a custom Authenticator

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;


class GMailAuthenticator extends Authenticator {
     String user;
     String pw;
     public GMailAuthenticator (String username, String password)
     {
        super();
        this.user = username;
        this.pw = password;
     }
    public PasswordAuthentication getPasswordAuthentication()
    {
       return new PasswordAuthentication(user, pw);
    }
}

Now use it in the Session

Session session = Session.getInstance(props, new GMailAuthenticator(username, password));

Summary of all ways to get info on dimensions of DataFrame or Series

There are a number of ways to get information on the attributes of your DataFrame or Series.

Create Sample DataFrame and Series

df = pd.DataFrame({'a':[5, 2, np.nan], 'b':[ 9, 2, 4]})
df

     a  b
0  5.0  9
1  2.0  2
2  NaN  4

s = df['a']
s

0    5.0
1    2.0
2    NaN
Name: a, dtype: float64

shape Attribute

The shape attribute returns a two-item tuple of the number of rows and the number of columns in the DataFrame. For a Series, it returns a one-item tuple.

df.shape
(3, 2)

s.shape
(3,)

len function

To get the number of rows of a DataFrame or get the length of a Series, use the len function. An integer will be returned.

len(df)
3

len(s)
3

size attribute

To get the total number of elements in the DataFrame or Series, use the size attribute. For DataFrames, this is the product of the number of rows and the number of columns. For a Series, this will be equivalent to the len function:

df.size
6

s.size
3

ndim attribute

The ndim attribute returns the number of dimensions of your DataFrame or Series. It will always be 2 for DataFrames and 1 for Series:

df.ndim
2

s.ndim
1

The tricky count method

The count method can be used to return the number of non-missing values for each column/row of the DataFrame. This can be very confusing, because most people normally think of count as just the length of each row, which it is not. When called on a DataFrame, a Series is returned with the column names in the index and the number of non-missing values as the values.

df.count() # by default, get the count of each column

a    2
b    3
dtype: int64


df.count(axis='columns') # change direction to get count of each row

0    2
1    2
2    1
dtype: int64

For a Series, there is only one axis for computation and so it just returns a scalar:

s.count()
2

Use the info method for retrieving metadata

The info method returns the number of non-missing values and data types of each column

df.info()

<class 'pandas.core.frame.DataFrame'>
RangeIndex: 3 entries, 0 to 2
Data columns (total 2 columns):
a    2 non-null float64
b    3 non-null int64
dtypes: float64(1), int64(1)
memory usage: 128.0 bytes

Cross join :Cross Joins produce results that consist of every combination of rows from two or more tables. That means if table A has 3 rows and table B has 2 rows, a CROSS JOIN will result in 6 rows. There is no relationship established between the two tables – you literally just produce every possible combination.

Full outer Join : A FULL OUTER JOIN is neither "left" nor "right"— it's both! It includes all the rows from both of the tables or result sets participating in the JOIN. When no matching rows exist for rows on the "left" side of the JOIN, you see Null values from the result set on the "right." Conversely, when no matching rows exist for rows on the "right" side of the JOIN, you see Null values from the result set on the "left."

If you're interested in learning a language which supports massive parallelism better go for OpenCL since you don't have an NVIDIA GPU. You can run OpenCL on Intel CPUs, but at best you can learn to program SIMDs. Optimization on CPU and GPU are different. I really don't think you can use Intel card for GPGPU.

Something like this should work:

sh -c 'cd /tmp && exec pwd'

In my case i needed to update the npm version from 5.3.0 ? 5.4.2 .

Before i could use this -- npm i -g npm .. i needed to run two commands which perfectly solved my problem. It is highly likely that it will even solve your problem.

Step 1: sudo chown -R $USER /usr/local

Step 2: npm install -g cordova ionic

After this you should update your npm to latest version

Step 3: npm i -g npm

Then you are good to go. Hope This solves your problem. Cheers!!

To select the right location provider for your app, you can use Criteria objects:

Criteria myCriteria = new Criteria();
myCriteria.setAccuracy(Criteria.ACCURACY_HIGH);
myCriteria.setPowerRequirement(Criteria.POWER_LOW);
// let Android select the right location provider for you
String myProvider = locationManager.getBestProvider(myCriteria, true); 

// finally require updates at -at least- the desired rate
long minTimeMillis = 600000; // 600,000 milliseconds make 10 minutes
locationManager.requestLocationUpdates(myProvider,minTimeMillis,0,locationListener); 

Read the documentation for requestLocationUpdates for more details on how the arguments are taken into account:

The frequency of notification may be controlled using the minTime and minDistance parameters. If minTime is greater than 0, the LocationManager could potentially rest for minTime milliseconds between location updates to conserve power. If minDistance is greater than 0, a location will only be broadcasted if the device moves by minDistance meters. To obtain notifications as frequently as possible, set both parameters to 0.

More thoughts

• You can monitor the accuracy of the Location objects with Location.getAccuracy(), which returns the estimated accuracy of the position in meters.
• the Criteria.ACCURACY_HIGH criterion should give you errors below 100m, which is not as good as GPS can be, but matches your needs.
• You also need to monitor the status of your location provider, and switch to another provider if it gets unavailable or disabled by the user.
• The passive provider may also be a good match for this kind of application: the idea is to use location updates whenever they are requested by another app and broadcast systemwide.

As of Pandas 0.17 there is now a styling system which essentially provides formatted views of a DataFrame using Python format strings:

import pandas as pd
import numpy as np

constants = pd.DataFrame([('pi',np.pi),('e',np.e)],
                   columns=['name','value'])
C = constants.style.format({'name': '~~ {} ~~', 'value':'--> {:15.10f} <--'})
C

which displays

This is a view object; the DataFrame itself does not change formatting, but updates in the DataFrame are reflected in the view:

constants.name = ['pie','eek']
C

However it appears to have some limitations:

• Adding new rows and/or columns in-place seems to cause inconsistency in the styled view (doesn't add row/column labels):

  constants.loc[2] = dict(name='bogus', value=123.456)
  constants['comment'] = ['fee','fie','fo']
  constants
  

which looks ok but:

C

• Formatting works only for values, not index entries:

  constants = pd.DataFrame([('pi',np.pi),('e',np.e)],
                 columns=['name','value'])
  constants.set_index('name',inplace=True)
  C = constants.style.format({'name': '~~ {} ~~', 'value':'--> {:15.10f} <--'})
  C
  

You can change the decimal separator by changing the culture used to display the number. Beware however that this will change everything else about the number (eg. grouping separator, grouping sizes, number of decimal places). From your question, it looks like you are defaulting to a culture that uses a comma as a decimal separator.

To change just the decimal separator without changing the culture, you can modify the NumberDecimalSeparator property of the current culture's NumberFormatInfo.

Thread.CurrentCulture.NumberFormat.NumberDecimalSeparator = ".";

This will modify the current culture of the thread. All output will now be altered, meaning that you can just use value.ToString() to output the format you want, without worrying about changing the culture each time you output a number.

_{(Note that a neutral culture cannot have its decimal separator changed.)}

Here's a little "coup de pouce"

clearfix should contain the floating elements but in your html you have added clearfix only after floating right that is your pull-right so you should do like this:

<div class="clearfix">
  <div id="sidebar">
    <ul>
      <li>A</li>
      <li>A</li>
      <li>C</li>
      <li>D</li>
      <li>E</li>
      <li>F</li>
      <li>...</li>
      <li>Z</li>
    </ul>
  </div>
  <div id="main">
    <div>
      <div class="pull-right">
        <a>RIGHT</a>
      </div>
    </div>
  <div>MOVED BELOW Z</div>
</div>

see this demo

Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden; as you have done in your main.

In order to find out what's wrong you can use gradle's signingReport command.

On mac:

./gradlew signingReport

On Windows:

gradlew signingReport

One of the Related posts gave me the (simple) answer.

Apparently the auto value on the grid-template-rows property does exactly what I was looking for.

.grid {
    display:grid;
    grid-template-columns: 1fr 1.5fr 1fr;
    grid-template-rows: auto auto 1fr 1fr 1fr auto auto;
    grid-gap:10px;
    height: calc(100vh - 10px);
}

$host is a variable of the Core module.

$host

This variable is equal to line Host in the header of request or name of the server processing the request if the Host header is not available.

This variable may have a different value from $http_host in such cases: 1) when the Host input header is absent or has an empty value, $host equals to the value of server_name directive; 2)when the value of Host contains port number, $host doesn't include that port number. $host's value is always lowercase since 0.8.17.

$http_host is also a variable of the same module but you won't find it with that name because it is defined generically as $http_HEADER (ref).

$http_HEADER

The value of the HTTP request header HEADER when converted to lowercase and with 'dashes' converted to 'underscores', e.g. $http_user_agent, $http_referer...;

Summarizing:

• $http_host equals always the HTTP_HOST request header.
• $host equals $http_host, lowercase and without the port number (if present), except when HTTP_HOST is absent or is an empty value. In that case, $host equals the value of the server_name directive of the server which processed the request.

To check whether a process/command returned 0 or not, use the operators && == 0 or not == 0 ||:

Just add operator to your script:

execute_command && (

       echo\Return 0, with no execution error
) || (
        echo\Return non 0, something went wrong
     )

command && echo\Return 0 || echo\Return non 0

• For details on Operators' behavior see: Conditional Execution || && ...

use string's replace method:

"this should be connected".replace(" ", "_")

"this_should_be_disconnected".replace("_", " ")

define I use for global constants.

const I use for class constants.

You cannot define into class scope, and with const you can. Needless to say, you cannot use const outside class scope.

Also, with const, it actually becomes a member of the class, and with define, it will be pushed to global scope.

To revert modified files:

sudo svn revert
svn status|grep "^ *M" | sed -e 's/^ *M *//'

In vi on Red Hat, I was able to insert carriage returns using just the \r character. I believe this internally executes 'ex' instead of 'sed', but it's similar, and vi can be another way to do bulk edits such as code patches. For example. I am surrounding a search term with an if statement that insists on carriage returns after the braces:

:.,$s/\(my_function(.*)\)/if(!skip_option){\r\t\1\r\t}/

Note that I also had it insert some tabs to make things align better.

For me, the problem was:

I used to hibernate my PC instead of shutting down due to the scale of the project. I was lazy enough to reopen all programs.

Before trying anything else, I recommend you to do the following simple things. Otherwise, you will be messed up your MySQL server.

1. Open your task manager and End the XAMPP process.
2. Re-run the XAMPP application as Administrator.

If not works,

1. Save all unsaved programs and restart the PC.
2. Run XAMMP as administrator.

Also, make sure to check 3306 & 5040 ports. These two ports are required to run MySQL on default settings.

Check @Ryan Williams answer to find of why it's good to run XAMPP as administrator.

The answer to my comment above on the Original Question makes me think this is all he wants:

loopnum = 0
word = 'afrykanerskojezyczny'
wordlist = ['afrykanerskojezycznym','afrykanerskojezyczni','nieafrykanerskojezyczni']
for i in wordlist:
    wordlist[loopnum] = word
    loopnum += 1

This will do the following:

For every value in wordlist, set that value of the wordlist to the origional code.

All you have to do is put this piece of code where you need to change wordlist, making sure you store the words you need to change in wordlist, and that the original word is correct.

Hope this helps!

There is an easy method to wrap your data and send it to server as if you were sending an HTML form using POST. you can do that using FormData object as following:

data = new FormData()
data.set('Foo',1)
data.set('Bar','boo')

let request = new XMLHttpRequest();
request.open("POST", 'some_url/', true);
request.send(data)

now you can handle the data on the server-side just like the way you deal with reugular HTML Forms.

Additional Info

It is advised that you must not set Content-Type header when sending FormData since the browser will take care of that.

You also can use in the startup class constructor to add json file (where the connection string lies) to the configuration. Example:

    IConfigurationRoot _config;
    public Startup(IHostingEnvironment env)
    {
        var builder = new ConfigurationBuilder()
            .SetBasePath(env.ContentRootPath)
            .AddJsonFile("appsettings.json");

        _config = builder.Build();
    }

Please check the UTM coordinate system https://en.wikipedia.org/wiki/Universal_Transverse_Mercator_coordinate_system.

These values must be in meters for a specific map projection. For example, the peak of Mount Assiniboine (at 50°52'10"N 115°39'03"W) in UTM Zone 11 is represented by 11U 594934.108296 5636174.091274 where (594934.108296, 5636174.091274) are in meters.

LPCWSTR is equivalent to wchar_t const *. It's a pointer to a wide character string that won't be modified by the function call.

You can assign to LPCWSTRs by prepending a L to a string literal: LPCWSTR *myStr = L"Hello World";

LPCTSTR and any other T types, take a string type depending on the Unicode settings for your project. If _UNICODE is defined for your project, the use of T types is the same as the wide character forms, otherwise the Ansi forms. The appropriate function will also be called this way: FindWindowEx is defined as FindWindowExA or FindWindowExW depending on this definition.

<string-array name="array_name">
<item>Array Item One</item>
<item>Array Item Two</item>
<item>Array Item Three</item>
</string-array>

In your layout:

<Spinner 
        android:id="@+id/spinner"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:drawSelectorOnTop="true"
        android:entries="@array/array_name"
    />

If you want more than one style this is the correct full answer. This is div with class and style:

<div className="class-example" style={{width: '300px', height: '150px'}}></div>

I had this problem in one legacy application that create prepared statement dynamically.

String firstName;
StringBuilder query =new StringBuilder("select id, name from employee where country_Code=1");
query.append("and  name like '");
query.append(firstName + "' ");
query.append("and ssn=?");
PreparedStatement preparedStatement =new prepareStatement(query.toString());

when it try to set value for ssn, it was giving invalid column index error, and finally found out that it is caused by firstName having ' within; that disturb the syntax.

What Tyler Rinker says is correct:

AQ2 <- airquality
AQ2[is.na(AQ2)] <- 0

will do just this.

What you are originally doing is that you are taking from airquality all those rows (cases) that are complete. So, all the cases that do not have any NA's in them, and keep only those.

you could do:

var scriptTag = document.createElement("script");
scriptTag.type = "text/javascript";
scriptTag.src = "script_source_here";
(document.getElementsByTagName("head")[0] || document.documentElement ).appendChild(scriptTag);

a negative index will count from the end of the list, so:

num_list[-9:]

Use DateTime::createFromFormat

$date = date_create_from_format('d/m/Y:H:i:s', $s);
$date->getTimestamp();

You can get the view Back if you put an ID to your Layout.

<RelativeLayout
    android:id="@+id/my_relative_layout_id"

And call it from findViewById ...

grep -Fxq "String to be found" | ls -a

• grep will helps you to check content
• ls will list all the Files

A trivial approach would be to replace

<[^>]*>

with nothing. But depending on how ill-structured your input is that may well fail.

i have used this and solved my

-webkit-appearance:none;

The error message you are getting is a result of Git still thinking that you have not resolved the merge conflicts. In fact, you already have, but you need to tell Git that you have done this by adding the resolved files to the index.

This has the side effect that you could actually just add the files without resolving the conflicts, and Git would still think that you have. So you should be diligent in making sure that you have really resolved the conflicts. You could even run the build and test the code before you commit.
