You will need to use JS to send the URL back with a variable in it such as: http://www.site.com/index.php?uid=1

by using something like this in JS:

window.location.href=”index.php?uid=1";

Then in the PHP code use $_GET:

$somevar = $_GET["uid"]; //puts the uid varialbe into $somevar

Functions in Python are first-class objects. But your function definition is a bit off.

def myfunc(anotherfunc, extraArgs, extraKwArgs):
  return anotherfunc(*extraArgs, **extraKwArgs)

The issue you're encountering is that even though the method emptyList() returns List<T>, you haven't provided it with the type, so it defaults to returning List<Object>. You can supply the type parameter, and have your code behave as expected, like this:

public Person(String name) {
  this(name,Collections.<String>emptyList());
}

Now when you're doing straight assignment, the compiler can figure out the generic type parameters for you. It's called type inference. For example, if you did this:

public Person(String name) {
  List<String> emptyList = Collections.emptyList();
  this(name, emptyList);
}

then the emptyList() call would correctly return a List<String>.

This is the easiest solution in my opinion is to select all the element which has certain data attribute:

var data = $("#dataTable[data-timer]");
var diffs = [];

for(var i = 0; i + 1 < data.length; i++) {
    diffs[i] = data[i + 1] - data[i];
}

alert(diffs.join(', '));

Here is the screenshot of how it works.

import java.io.*;


public class FileRead {


    public static void main(String[] args) throws IOException {


        File f=new File("C:\\Documents and Settings\\abc\\Desktop\\abc.pdf");

        OutputStream oos = new FileOutputStream("test.pdf");

        byte[] buf = new byte[8192];

        InputStream is = new FileInputStream(f);

        int c = 0;

        while ((c = is.read(buf, 0, buf.length)) > 0) {
            oos.write(buf, 0, c);
            oos.flush();
        }

        oos.close();
        System.out.println("stop");
        is.close();

    }

}

The easiest way so far. Hope this helps.

I created a function to handle this situation, thought I would share it.

getDirectDecendent(elem, selector, all){
    const tempID = randomString(10) //use your randomString function here.
    elem.dataset.tempid = tempID;

    let returnObj;
    if(all)
        returnObj = elem.parentElement.querySelectorAll(`[data-tempid="${tempID}"] > ${selector}`);
    else
        returnObj = elem.parentElement.querySelector(`[data-tempid="${tempID}"] > ${selector}`);

    elem.dataset.tempid = '';
    return returnObj;
}

In essence what you are doing is generating a random-string (randomString function here is an imported npm module, but you can make your own.) then using that random string to guarantee that you get the element you are expecting in the selector. Then you are free to use the > after that.

The reason I am not using the id attribute is that the id attribute may already be used and I don't want to override that.

you can render your recaptcha using following code

<div id="recapchaWidget" class="g-recaptcha"></div>

<script type="text/javascript">
   var widId = "";
   var onloadCallback = function ()
   {
    widId = grecaptcha.render('recapchaWidget', {
    'sitekey':'Your Site Key'
            });
   };
 </script>

 <script src="https://www.google.com/recaptcha/api.js?onload=onloadCallback&render=explicit" async defer></script>

Then you can validate your recaptcha by using "IsRecapchaValid()" method as follows.

 <script type="text/javascript">
     function IsRecapchaValid()
      {
      var res = grecaptcha.getResponse(widId);
      if (res == "" || res == undefined || res.length == 0)
         {
          return false;
         }
       return true;
      }
 </script>

Try this:

private boolean isPackageInstalled(String packageName, PackageManager packageManager) {
    try {
        packageManager.getPackageInfo(packageName, 0);
        return true;
    } catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}

It attempts to fetch information about the package whose name you passed in. Failing that, if a NameNotFoundException was thrown, it means that no package with that name is installed, so we return false.

Note that we pass in a PackageManager instead of a Context, so that the method is slightly more flexibly usable and doesn't violate the law of Demeter. You can use the method without access to a Context instance, as long as you have a PackageManager instance.

Use it like this:

public void someMethod() {
    // ...

    PackageManager pm = context.getPackageManager();
    boolean isInstalled = isPackageInstalled("com.somepackage.name", pm);

    // ...
}

You're correct that this is really painful to hand out to others, but if you have to, this is how you do it.

1. Just extract the .ocx file from the .cab file (it is similar to a zip)
2. Copy to the system folder (c:\windows\sysWOW64 for 64 bit systems and c:\windows\system32 for 32 bit)
3. Use regsvr32 through the command prompt to register the file (e.g. "regsvr32 c:\windows\sysWOW64\mscomct2.ocx")

Dates are stored in their timestamp format. If you want everything that belongs to a specific month, query for the start and the end of the month.

var start = new Date(2010, 11, 1);
var end = new Date(2010, 11, 30);

db.posts.find({created_on: {$gte: start, $lt: end}});

My ~/.gradle/caches/ folder was using 14G.

After using the following solution, it went from 14G to 1.7G.

$ rm -rf ~/.gradle/caches/transforms-*
$ rm -rf ~/.gradle/caches/build-cache-*

Bonus

This command shows you in detail the used cache space

$ sudo du -ah --max-depth = 1 ~/.gradle/caches/ | sort -hr

One place where it's useful is for UI activities, like setting a spinner before a lengthy operation:

- (void) handleDoSomethingButton{

    [mySpinner startAnimating];

    (do something lengthy)
    [mySpinner stopAnimating];
}

will not work, because you are blocking the main thread during your lengthy thing and not letting UIKit actually start the spinner.

- (void) handleDoSomethingButton{
     [mySpinner startAnimating];

     dispatch_async (dispatch_get_main_queue(), ^{
          (do something lengthy)
          [mySpinner stopAnimating];
    });
}

will return control to the run loop, which will schedule UI updating, starting the spinner, then will get the next thing off the dispatch queue, which is your actual processing. When your processing is done, the animation stop is called, and you return to the run loop, where the UI then gets updated with the stop.

You could try:

agg <- aggregate(list(x$val1, x$val2, x$val3, x$val4), by = list(x$id1, x$id2), mean)

I wrote a quick little Python script that is callable from a bash command line. It takes the name of the module, class and method you want to call and the parameters you want to pass. I call it PyRun and left off the .py extension and made it executable with chmod +x PyRun so that I can just call it quickly as follow:

./PyRun PyTest.ClassName.Method1 Param1

Save this in a file called PyRun

#!/usr/bin/env python
#make executable in bash chmod +x PyRun

import sys
import inspect
import importlib
import os

if __name__ == "__main__":
    cmd_folder = os.path.realpath(os.path.abspath(os.path.split(inspect.getfile( inspect.currentframe() ))[0]))
    if cmd_folder not in sys.path:
        sys.path.insert(0, cmd_folder)

    # get the second argument from the command line      
    methodname = sys.argv[1]

    # split this into module, class and function name
    modulename, classname, funcname = methodname.split(".")

    # get pointers to the objects based on the string names
    themodule = importlib.import_module(modulename)
    theclass = getattr(themodule, classname)
    thefunc = getattr(theclass, funcname)

    # pass all the parameters from the third until the end of 
    # what the function needs & ignore the rest
    args = inspect.getargspec(thefunc)
    z = len(args[0]) + 2
    params=sys.argv[2:z]
    thefunc(*params)

Here is a sample module to show how it works. This is saved in a file called PyTest.py:

class SomeClass:
 @staticmethod
 def First():
     print "First"

 @staticmethod
 def Second(x):
    print(x)
    # for x1 in x:
    #     print x1

 @staticmethod
 def Third(x, y):
     print x
     print y

class OtherClass:
    @staticmethod
    def Uno():
        print("Uno")

Try running these examples:

./PyRun PyTest.SomeClass.First
./PyRun PyTest.SomeClass.Second Hello
./PyRun PyTest.SomeClass.Third Hello World
./PyRun PyTest.OtherClass.Uno
./PyRun PyTest.SomeClass.Second "Hello"
./PyRun PyTest.SomeClass.Second \(Hello, World\)

Note the last example of escaping the parentheses to pass in a tuple as the only parameter to the Second method.

If you pass too few parameters for what the method needs you get an error. If you pass too many, it ignores the extras. The module must be in the current working folder, put PyRun can be anywhere in your path.

if you can load jQuery from your own server, then you can append this to your jQuery file:

jQuery(document).trigger('jquery.loaded');

then you can bind to that triggered event.

You can simply figure out :

git log --cherry master...experimental

--cherry option is a synonym for --right-only --cherry-mark --no-merges

git-log man page said

it's useful to limit the output to the commits on our side and mark those that have been applied to the other side of a forked history with git log --cherry upstream...mybranch, similar to git cherry upstream mybranch.

FYI. --cherry-pick omits equivalent commits but --cherry-marks doesn't. It's useful to find rebase and force updated changes between upstream and co-working public branch

PL/SQL: numeric or value error: character string buffer too small

is due to the fact that you declare a string to be of a fixed length (say 20), and at some point in your code you assign it a value whose length exceeds what you declared.

for example:

myString VARCHAR2(20);
myString :='abcdefghijklmnopqrstuvwxyz'; --length 26

will fire such an error

Your server needs to have the php modules installed so it can parse php code.

If you are on ubuntu you can do this easily with

sudo apt-get install apache2

sudo apt-get install php5

sudo apt-get install libapache2-mod-php5

sudo /etc/init.d/apache2 restart

Otherwise you may compile apache with php: http://dan.drydog.com/apache2php.html

Specifying your server OS will help others to answer more specifically.

You don't need javascript for doing so. Just delete the onClick and write the php Admin.php file like this:

<!-- HTML STARTS-->
<?php
//If all the required fields are filled
if (!empty($GET_['fullname'])&&!empty($GET_['email'])&&!empty($GET_['name']))
{
function addNewContact()
    {
    $new = '{';
    $new .= '"fullname":"' . $_GET['fullname'] . '",';
    $new .= '"email":"' . $_GET['email'] . '",';
    $new .= '"phone":"' . $_GET['phone'] . '",';
    $new .= '}';
    return $new;
    }

function saveContact()
    {
    $datafile = fopen ("data/data.json", "a+");
    if(!$datafile){
        echo "<script>alert('Data not existed!')</script>";
        } 
    else{
        $contact_list = $contact_list . addNewContact();
        file_put_contents("data/data.json", $contact_list);
        }
    fclose($datafile);
    }

// Call the function saveContact()
saveContact();
echo "Thank you for joining us";
}
else //If the form is not submited or not all the required fields are filled

{ ?>

<form>
    <fieldset>
        <legend>Add New Contact</legend>
        <input type="text" name="fullname" placeholder="First name and last name" required /> <br />
        <input type="email" name="email" placeholder="[email protected]" required /> <br />
        <input type="text" name="phone" placeholder="Personal phone number: mobile, home phone etc." required /> <br />
        <input type="submit" name="submit" class="button" value="Add Contact"/>
        <input type="button" name="cancel" class="button" value="Reset" />
    </fieldset>
</form>
<?php }
?>
<!-- HTML ENDS -->

Thought I don't like the PHP bit. Do you REALLY want to create a file for contacts? It'd be MUCH better to use a mysql database. Also, adding some breaks to that file would be nice too...

Other thought, IE doesn't support placeholder.

In addition to the answers here, I can explain a little bit. It is actually a mathematical problem.

321 is the total of 300 + 20 + 1.

If you divide 300 by 100, you get 3.

If you divide 20 by 10, you get 2.

If you divide 1 by 1, you get 1.

At the end of these operations, you can sum up all of them and you get 6.

public class SumOfDigits{

public static void main(String[] args) {
    int myVariable = 542;
    int checker = 1;
    int result = 0;
    int updater = 0;

    //This while finds the size of the myVariable
    while (myVariable % checker != myVariable) {
        checker = checker * 10;
    }

    //This for statement calculates, what you want.
    for (int i = checker / 10; i > 0; i = i / 10) {

        updater = myVariable / i;
        result += updater;
        myVariable = myVariable - (updater * i);
    }

    System.out.println("The result is " + result);
}
}

It is very friendly framework for Notification Area Application... it is enough to add NotificationIcon to base form and change auto-generated code to code below:

public partial class Form1 : Form
{
    private bool hidden = false;

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        this.ShowInTaskbar = false;
        //this.WindowState = FormWindowState.Minimized;
        this.Hide();
        hidden = true;
    }

    private void notifyIcon1_Click(object sender, EventArgs e)
    {
        if (hidden) // this.WindowState == FormWindowState.Minimized)
        {
            // this.WindowState = FormWindowState.Normal;
            this.Show();
            hidden = false;
        }
        else
        {
            // this.WindowState = FormWindowState.Minimized;
            this.Hide();
            hidden = true;
        }
    }
}

Dowski's method is good if all of your callbacks are always going to be present and you are happy with them being dependant on each other.

If you want the callbacks to be independent of each other, though, you could be to take advantage of bubbling and attach subsequent events as delegates to parent elements. The handlers on a parent elements will be triggered after the handlers on the element, continuing right up to the document. This is quite good as you can use event.stopPropagation(), event.preventDefault(), etc to skip handlers and cancel or un-cancel the action.

$( '#mybutton' ).click( function(e) { 
    // Do stuff first
} );

$( '#mybutton' ).click( function(e) { 
    // Do other stuff first
} );

$( document ).delegate( '#mybutton', 'click', function(e) {
    // Do stuff last
} );

Or, if you don't like this, you could use Nick Leaches bindLast plugin to force an event to be bound last: https://github.com/nickyleach/jQuery.bindLast.

Or, if you are using jQuery 1.5, you could also potentially do something clever with the new Deferred object.

This should work with only one loop:

function checkIfArrayIsUnique(arr) {
    var map = {}, i, size;

    for (i = 0, size = arr.length; i < size; i++){
        if (map[arr[i]]){
            return false;
        }

        map[arr[i]] = true;
    }

    return true;
}

For anyone who might stumble upon this, if all the other answers do not help and you are on Windows, know that there is currently a big issue with spawn on Windows and the PATHEXT environment variable that can cause certain calls to spawn to not work depending on how the target command is installed.

Lets say to want to make default version as 10.19.0.

nvm alias default v10.19.0

But it will give following error

! WARNING: Version 'v10.19.0' does not exist.
default -> v10.19.0 (-> N/A)

In That case you need to run two commands in the following order

# Install the version that you would like 
nvm install 10.19.0

# Set 10.19.0 (or another version) as default
nvm alias default 10.19.0

You could try using Strings with a separator which does not appear in any element.

if ("|a|b|c|".contains("|a|"))

You can understand it best by relating it to Plain JS functions.

Simply put,

State is the local state of the component which cannot be accessed and modified outside of the component. It's equivalent to local variables in a function.

Plain JS Function

const DummyFunction = () => {
  let name = 'Manoj';
  console.log(`Hey ${name}`)
}

React Component

class DummyComponent extends React.Component {
  state = {
    name: 'Manoj'
  }
  render() {
    return <div>Hello {this.state.name}</div>;
  }

Props, on the other hand, make components reusable by giving components the ability to receive data from their parent component in the form of props. They are equivalent to function parameters.

Plain JS Function

const DummyFunction = (name) => {

Yes, you just need to add a parenthesis :

SELECT col1 as a, (CASE WHEN a = 'test' THEN 'yes' END) as value FROM table;

The other answers point out how to accomplish this, but you should keep in mind the consequences since this is a remote repository.

The git tag man page, in the On Retagging section, has a good explanation of how to courteously inform the remote repo's other users of the change. They even give a handy announcement template for communicating how others should get your changes.

you can wrap reserved words in square brackets to avoid these kinds of errors:

dbo.TableName.[Date]

Let is a mathematical statement that was adopted by early programming languages like Scheme and Basic. Variables are considered low level entities not suitable for higher levels of abstraction, thus the desire of many language designers to introduce similar but more powerful concepts like in Clojure, F#, Scala, where let might mean a value, or a variable that can be assigned, but not changed, which in turn lets the compiler catch more programming errors and optimize code better.

JavaScript has had var from the beginning, so they just needed another keyword, and just borrowed from dozens of other languages that use let already as a traditional keyword as close to var as possible, although in JavaScript let creates block scope local variable instead.

TEXT is a string data type that can store up to 65,535 characters. But still if you want to store more data then change its data type to LONGTEXT

ALTER TABLE name_tabel CHANGE text_field LONGTEXT CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL;

Yes, that is normal behavior. You basically read to the end of the file the first time (you can sort of picture it as reading a tape), so you can't read any more from it unless you reset it, by either using f.seek(0) to reposition to the start of the file, or to close it and then open it again which will start from the beginning of the file.

If you prefer you can use the with syntax instead which will automatically close the file for you.

e.g.,

with open('baby1990.html', 'rU') as f:
  for line in f:
     print line

once this block is finished executing, the file is automatically closed for you, so you could execute this block repeatedly without explicitly closing the file yourself and read the file this way over again.

You can just use the View.setId(integer) for this. In the XML, even though you're setting a String id, this gets converted into an integer. Due to this, you can use any (positive) Integer for the Views you add programmatically.

According to View documentation

The identifier does not have to be unique in this view's hierarchy. The identifier should be a positive number.

So you can use any positive integer you like, but in this case there can be some views with equivalent id's. If you want to search for some view in hierarchy calling to setTag with some key objects may be handy.

SELECT COUNT(job_id) FROM jobs WHERE posted_date < NOW()-30;

Now() returns the current Date and Time.

There is no subquery needed with this statement, which is better written as

select u.* 
from Users u, CompanyRolesToUsers c
where u.Id = c.UserId        --join just specified here, perfectly fine
and u.lastname like '%fra%'
and c.CompanyRoleId in (2,3,4)

or

select u.* 
from Users u inner join CompanyRolesToUsers c
             on u.Id = c.UserId    --explicit "join" statement, no diff from above, just preference
where u.lastname like '%fra%'
  and c.CompanyRoleId in (2,3,4)

That being said, in LINQ it would be

from u in Users
from c in CompanyRolesToUsers 
where u.Id == c.UserId &&
      u.LastName.Contains("fra") &&
      selectedRoles.Contains(c.CompanyRoleId)
select u

or

from u in Users
join c in CompanyRolesToUsers 
       on u.Id equals c.UserId
where u.LastName.Contains("fra") &&
      selectedRoles.Contains(c.CompanyRoleId)
select u

Which again, are both respectable ways to represent this. I prefer the explicit "join" syntax in both cases myself, but there it is...

This should work...

JavaScriptSerializer ser = new JavaScriptSerializer();
var records = new ser.Deserialize<List<Record>>(jsonData);

public class Person
{
    public string Name;
    public int Age;
    public string Location;
}
public class Record
{
    public Person record;
}

echo '
<html>
<body>
</body>
</html>
';

or

echo "<html>\n<body>\n</body>\n</html>\n";

When the array consists of strings one has to alter the code. This can be the case, if the array is a result from a databank request. This code works:

alert(
["1", "2", "3", "4"].reduce((a, b) => Number(a) + Number(b), 0)
);

Here, ["1", "2", "3", "4"] ist the string array and the function Number() converts the strings to numbers.

I had a similar problem in a large multi-module project with many dependencies among the modules. What worked for me, was to attempt to build separately from command line all the modules that failed to build within Android Studio. That gave me indications on resources missing in each project. From the project level in my console I did:

$ cd moduleName
$ ../gradlew assembleDebug

This provided me with a number of 'No resource found that matches the given name' errors, that weren't shown before, when I build the project as a whole.

Here's how I'm handling my exceptions. The idea is to do try solving the issue if that's easy, and later add a more desirable solution if possible. Don't solve the issue in the code that generates the exception, or that code loses track of the original algorithm, which should be written to-the-point. However, pass what data is needed to solve the issue, and return a lambda just in case you can't solve the problem outside of the code that generates it.

path = 'app.p'

def load():
    if os.path.exists(path):
        try:
            with open(path, 'rb') as file:
                data = file.read()
                inst = pickle.load(data)
        except Exception as e:
            inst = solve(e, 'load app data', easy=lambda: App(), path=path)()
    else:
        inst = App()
    inst.loadWidgets()

# e.g. A solver could search for app data if desc='load app data'
def solve(e, during, easy, **kwargs):
    class_name = e.__class__.__name__
    print(class_name + ': ' + str(e))
    print('\t during: ' + during)
    return easy

For now, since I don't want to think tangentially to my app's purpose, I haven't added any complicated solutions. But in the future, when I know more about possible solutions (since the app is designed more), I could add in a dictionary of solutions indexed by during.

In the example shown, one solution might be to look for app data stored somewhere else, say if the 'app.p' file got deleted by mistake.

For now, since writing the exception handler is not a smart idea (we don't know the best ways to solve it yet, because the app design will evolve), we simply return the easy fix which is to act like we're running the app for the first time (in this case).

The problem is that arr is not (declared as) a 2D array, and you are treating it as if it were 2D.

I'd try to declare i outside of the loop!

Good luck on solving 3n+1 :-)

Here's an example:

#include <stdio.h>

int main() {

   int i;

   /* for loop execution */
   for (i = 10; i < 20; i++) {
       printf("i: %d\n", i);
   }   

   return 0;
}

Read more on for loops in C here.

Try this:

Select u.[username]
      ,u.[ip]
      ,q.[time_stamp]
From [users] As u
Inner Join (
    Select [username]
          ,max(time_stamp) as [time_stamp]
    From [users]
    Group By [username]) As [q]
On u.username = q.username
And u.time_stamp = q.time_stamp

In our case were were getting this error because we had accidentally flipped the order of comparison of s1 and s2. So watch out for that. It was obviously way more complicated than the following but this is an illustration:

s1 == s2   
    return 0;
s2 > s1 
    return 1;
s1 < s2 
    return -1;

To disable resizing completely:

textarea {
    resize: none;
}

To allow only vertical resizing:

textarea {
    resize: vertical;
}

To allow only horizontal resizing:

textarea {
    resize: horizontal;
}

Or you can limit size:

textarea {
    max-width: 100px; 
    max-height: 100px;
}

To limit size to parents width and/or height:

textarea {
    max-width: 100%; 
    max-height: 100%;
}

Good news! awk field separator can be a regular expression. You just need to use -F"<separator1>|<separator2>|...":

awk -F"/|=" -vOFS='\t' '{print $3, $5, $NF}' file

Returns:

tc0001  tomcat7.1  demo.example.com
tc0001  tomcat7.2  quest.example.com
tc0001  tomcat7.5  www.example.com

Here:

• -F"/|=" sets the input field separator to either / or =. Then, it sets the output field separator to a tab.

• -vOFS='\t' is using the -v flag for setting a variable. OFS is the default variable for the Output Field Separator and it is set to the tab character. The flag is necessary because there is no built-in for the OFS like -F.

• {print $3, $5, $NF} prints the 3rd, 5th and last fields based on the input field separator.

See another example:

$ cat file
hello#how_are_you
i#am_very#well_thank#you

This file has two fields separators, # and _. If we want to print the second field regardless of the separator being one or the other, let's make both be separators!

$ awk -F"#|_" '{print $2}' file
how
am

Where the files are numbered as follows:

hello#how_are_you           i#am_very#well_thank#you
^^^^^ ^^^ ^^^ ^^^           ^ ^^ ^^^^ ^^^^ ^^^^^ ^^^
  1    2   3   4            1  2   3    4    5    6

I add a little extra comment just in case it helps anyone because I found this exchange useful but needed this little extra bit of info to get it all working.

To log to a specific facility using SysLogHandler you need to specify the facility value. Say for example that you have defined:

local3.* /var/log/mylog

in syslog, then you'll want to use:

handler = logging.handlers.SysLogHandler(address = ('localhost',514), facility=19)

and you also need to have syslog listening on UDP to use localhost instead of /dev/log.

I had this problem and I nearly tore my hair out, and I wasn't able to find the appropriate answer on the net. I was trying to control the background color of the selected row in a WPF DataGrid. It just wouldn't do it. In my case, the reason was that I also had a CellStyle in my datagrid, and the CellStyle overrode the RowStyle I was setting. Interestingly so, because the CellStyle wasn't even setting the background color, which was instead bing set by the RowBackground and AlternateRowBackground properties. Nevertheless, trying to set the background colour of the selected row did not work at all when I did this:

        <DataGrid ... >
        <DataGrid.RowBackground>
            ...
        </DataGrid.RowBackground>
        <DataGrid.AlternatingRowBackground>
            ...
        </DataGrid.AlternatingRowBackground>
        <DataGrid.RowStyle>
            <Style TargetType="{x:Type DataGridRow}">
                <Style.Triggers>
                    <Trigger Property="IsSelected" Value="True">
                        <Setter Property="Background" Value="Pink"/>
                        <Setter Property="Foreground" Value="White"/>
                    </Trigger>
                </Style.Triggers>
            </Style>
        </DataGrid.RowStyle>
        <DataGrid.CellStyle>
            <Style TargetType="{x:Type DataGridCell}">
                <Setter Property="Foreground" Value="{Binding MyProperty}" />
            </Style>
        </DataGrid.CellStyle>

and it did work when I moved the desired style for the selected row out of the row style and into the cell style, like so:

    <DataGrid ... >
        <DataGrid.RowBackground>
            ...
        </DataGrid.RowBackground>
        <DataGrid.AlternatingRowBackground>
            ...
        </DataGrid.AlternatingRowBackground>
        <DataGrid.CellStyle>
            <Style TargetType="{x:Type DataGridCell}">
                <Setter Property="Foreground" Value="{Binding MyProperty}" />
                <Style.Triggers>
                    <Trigger Property="IsSelected" Value="True">
                        <Setter Property="Background" Value="Pink"/>
                        <Setter Property="Foreground" Value="White"/>
                    </Trigger>
                </Style.Triggers>
            </Style>
        </DataGrid.CellStyle>

Just posting this in case someone has the same problem.

1. Install packages: babel-core, babel-polyfill, babel-preset-es2015
2. Create .babelrc with contents: { "presets": ["es2015"] }
3. Do not put import statement in your main entry file, use another file eg: app.js and your main entry file should required babel-core/register and babel-polyfill to make babel works separately at the first place before anything else. Then you can require app.js where import statement.

Example:

index.js

require('babel-core/register');
require('babel-polyfill');
require('./app');

app.js

import co from 'co';

It should works with node index.js.

In case somebody needs to append the output and not overriding, it is possible to use "-a" or "--append" option of "tee" command :

ls 2>&1 | tee -a /tmp/ls.txt
ls 2>&1 | tee --append /tmp/ls.txt

Graphviz is evidently included in Anaconda so as to be used with pydot or pydot-ng (both of which are included in Anaconda). You may want to consider using one of those instead of the 'graphviz' Python module.

I'm using simple alias to create pull request,

alias pr='open -n -a "Google Chrome" --args "https://github.com/user/repo/compare/pre-master...nawarkhede:$(git_current_branch)\?expand\=1"'

I know it's not exactly what you're asking, but, for replacing a comma with a newline, this works great:

tr , '\n' < file

Perhaps "the most pythonic way" should include handling the case where list1 and list2 are not the same size. Applying some of these methods will quietly give you an answer. The numpy approach will let you know, most likely with a ValueError.

Example:

import numpy as np
>>> list1 = [ 1, 2 ]
>>> list2 = [ 1, 2, 3]
>>> list3 = [ 1 ]
>>> [a + b for a, b in zip(list1, list2)]
[2, 4]
>>> [a + b for a, b in zip(list1, list3)]
[2]
>>> a = np.array (list1)
>>> b = np.array (list2)
>>> a+b
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: operands could not be broadcast together with shapes (2) (3)

Which result might you want if this were in a function in your problem?

Example of solution with reflection, passed method must be public

    public static void main(String[] args) {
        Program   obj = new Program();    //some object

        try {
            Method method = obj.getClass().getMethod("target");
            repeatMethod( 5, obj, method );
        } 
        catch ( NoSuchMethodException | IllegalAccessException | InvocationTargetException e) {
            System.out.println( e ); 
        }
    }

    static void repeatMethod (int times, Object object, Method method)
        throws IllegalAccessException, InvocationTargetException {

        for (int i=0; i<times; i++)
            method.invoke(object);
    }
    public void target() {                 //public is necessary
        System.out.println("target(): "+ ++i);
    }
}

Change these shortcuts in Visual Studio

Tools ? Options ? Environment ? Keyboard

and then change the command

"Edit.FormatDocument" or "Edit.FormatSelection"

assign the same shortcut alt + shift +f as in visual studio code in order to not remember another one and confuse between each other.

It is not at all obvious why one would want to concatenate the (decimal) "ascii values". What is certain is that concatenating them without leading zeroes (or some other padding or a delimiter) is useless -- nothing can be reliably recovered from such an output.

>>> tests = ["hi", "Hi", "HI", '\x0A\x29\x00\x05']
>>> ["".join("%d" % ord(c) for c in s) for s in tests]
['104105', '72105', '7273', '104105']

Note that the first 3 outputs are of different length. Note that the fourth result is the same as the first.

>>> ["".join("%03d" % ord(c) for c in s) for s in tests]
['104105', '072105', '072073', '010041000005']
>>> [" ".join("%d" % ord(c) for c in s) for s in tests]
['104 105', '72 105', '72 73', '10 41 0 5']
>>> ["".join("%02x" % ord(c) for c in s) for s in tests]
['6869', '4869', '4849', '0a290005']
>>>

Note no such problems.

From the docs of the flush method:

Flushes the output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.

The buffering is mainly done to improve the I/O performance. More on this can be read from this article: Tuning Java I/O Performance.

set a reference to the Scripting.Runtime library and then use the FileSystemObject:

Dim fso as New FileSystemObject, aFile as File

if (fso.FileExists("PathToFile")) then
    aFile = fso.GetFile("PathToFile")
    aFile.Delete
End if

If you want to know on which platform you are on out of "Linux", "Windows", or "Darwin" (Mac), without more precision, you should use:

>>> import platform
>>> platform.system()
'Linux'  # or 'Windows'/'Darwin'

The platform.system function uses uname internally.

Easiest solution is to create the column using the correct data type: DATE

For example:

1. Create table:

   create table test_date (mydate date);

2. Insert row:

   insert into test_date values (to_date('01-01-2011','dd-mm-yyyy'));

To get the month and year, do as follows:

select to_char(mydate, 'MM-YYYY') from test_date;

Your result will be as follows: 01-2011

Another cool function to use is "EXTRACT"

select extract(year from mydate) from test_date;

This will return: 2011

A big change that happened with Xcode 8 Beta 6 for Swift 3 was that id now imports as Any rather than AnyObject.

This means that parsedData is returned as a dictionary of most likely with the type [Any:Any]. Without using a debugger I could not tell you exactly what your cast to NSDictionary will do but the error you are seeing is because dict!["currently"]! has type Any

So, how do you solve this? From the way you've referenced it, I assume dict!["currently"]! is a dictionary and so you have many options:

First you could do something like this:

let currentConditionsDictionary: [String: AnyObject] = dict!["currently"]! as! [String: AnyObject]  

This will give you a dictionary object that you can then query for values and so you can get your temperature like this:

let currentTemperatureF = currentConditionsDictionary["temperature"] as! Double

Or if you would prefer you can do it in line:

let currentTemperatureF = (dict!["currently"]! as! [String: AnyObject])["temperature"]! as! Double

Hopefully this helps, I'm afraid I have not had time to write a sample app to test it.

One final note: the easiest thing to do, might be to simply cast the JSON payload into [String: AnyObject] right at the start.

let parsedData = try JSONSerialization.jsonObject(with: data as Data, options: .allowFragments) as! Dictionary<String, AnyObject>

It's because size_t can be anything other than an int (maybe a struct). The idea is that it decouples it's job from the underlying type.

In the first plate you have to check that:

• 1) You install a appropriate version of Crystal Reports SDK => http://downloads.i-theses.com/index.php?option=com_downloads&task=downloads&groupid=9&id=101 (for example)
• 2) Add reference to dll => crystaldecisions.reportappserver.commlayer.dll

Vector's iterators are random access iterators which means they look and feel like plain pointers.

You can access the nth element by adding n to the iterator returned from the container's begin() method, or you can use operator [].

std::vector<int> vec(10);
std::vector<int>::iterator it = vec.begin();

int sixth = *(it + 5);
int third = *(2 + it);
int second = it[1];

Alternatively you can use the advance function which works with all kinds of iterators. (You'd have to consider whether you really want to perform "random access" with non-random-access iterators, since that might be an expensive thing to do.)

std::vector<int> vec(10);
std::vector<int>::iterator it = vec.begin();

std::advance(it, 5);
int sixth = *it;

I faced the same problem, the following changes solved my problem.

$(document).ready(function() {
     $('.datatable').dataTable( {
            bSort: false,
            aoColumns: [ { sWidth: "45%" }, { sWidth: "45%" }, { sWidth: "10%", bSearchable: false, bSortable: false } ],
        "scrollY":        "200px",
        "scrollCollapse": true,
        "info":           true,
        "paging":         true
    } );
} );

the aoColumns array describes the width of each column and its sortable properties.

Another thing to mention this error will also appear when you order by a column number that does not exist.

This can't be done with pure HTML.

However if you have access to PHP on the Apache server (you tagged the post "apache") it can be done easilly - se the PHP glob function. If not - you might try Server Side Include - it's an Apache thing, and I don't know much about it.

sed -n 's/^potato:[[:space:]]*//p' file.txt

One can think of Grep as a restricted Sed, or of Sed as a generalized Grep. In this case, Sed is one good, lightweight tool that does what you want -- though, of course, there exist several other reasonable ways to do it, too.

In Debian NGINX environment i did the following.

Goto /etc/mysql/mysql.conf.d edit mysqld.cnf if you find log-error = /var/log/mysql/error.log add the following 2 lines bellow it.

general_log_file        = /var/log/mysql/mysql.log
general_log             = 1

To see the logs goto /var/log/mysql and tail -f mysql.log

Remember to comment these lines out once you are done with debugging if you are in production environment delete mysql.log as this log file will grow quickly and can be huge.

I found that I also had to set the Access Modifier in the Resources tab to 'Public' - by default it was set to Internal and my icon only appeared in design mode but not when I ran the application.

Look before you leap (LBYL):

if idx < len(array):
    array[idx]
else:
    # handle this

Easier to ask forgiveness than permission (EAFP):

try:
    array[idx]
except IndexError:
    # handle this

In Python, EAFP seems to be the popular and preferred style. It is generally more reliable, and avoids an entire class of bugs (time of check vs. time of use). All other things being equal, the try/except version is recommended - don't see it as a "last resort".

This excerpt is from the official docs linked above, endorsing using try/except for flow control:

This common Python coding style assumes the existence of valid keys or attributes and catches exceptions if the assumption proves false. This clean and fast style is characterized by the presence of many try and except statements.

Normally in Visual Studio 2015 you should create the dll project as a C++ -> CLR project from Visual Studio's templates, but you can technically enable it after the fact:

The critical property is called Common Language Runtime Support set in your project's configuration. It's found under Configuration Properties > General > Common Language Runtime Support.

When doing this, VS will probably not update the 'Target .NET Framework' option (like it should). You can manually add this by unloading your project, editing the your_project.xxproj file, and adding/updating the Target .NET framework Version XML tag.

For a sample, I suggest creating a new solution as a C++ CLR project and examining the XML there, perhaps even diffing it to make sure there's nothing very important that's out of the ordinary.

You can use the :before and :after pseudo-classes to put a multi-layered background on a element.

#divID : before {
    background: url(someImage);
}

#div : after {
    background : url(someotherImage) -10% no-repeat;
}

Use stripTrailingZeros().

I wanted to use JavaScript to change a form's action, so I could have different submit inputs within the same form linking to different pages.

I also had the added complication of using Apache rewrite to change example.com/page-name into example.com/index.pl?page=page-name. I found that changing the form's action caused example.com/index.pl (with no page parameter) to be rendered, even though the expected URL (example.com/page-name) was displayed in the address bar.

To get around this, I used JavaScript to insert a hidden field to set the page parameter. I still changed the form's action, just so the address bar displayed the correct URL.

function setAction (element, page)
{
  if(checkCondition(page))
  {
    /* Insert a hidden input into the form to set the page as a parameter.
     */
    var input = document.createElement("input");
    input.setAttribute("type","hidden");
    input.setAttribute("name","page");
    input.setAttribute("value",page);
    element.form.appendChild(input);

    /* Change the form's action. This doesn't chage which page is displayed,
     * it just make the URL look right.
     */
    element.form.action = '/' + page;
    element.form.submit();
  }
}

In the form:

<input type="submit" onclick='setAction(this,"my-page")' value="Click Me!" />

Here are my Apache rewrite rules:

RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-f
RewriteRule ^/(.*)$ %{DOCUMENT_ROOT}/index.pl?page=$1&%{QUERY_STRING}

I'd be interested in any explanation as to why just setting the action didn't work.

To access the raw RGB values of an UIImage in Swift 5 use the underlying CGImage and its dataProvider:

import UIKit

let image = UIImage(named: "example.png")!

guard let cgImage = image.cgImage,
    let data = cgImage.dataProvider?.data,
    let bytes = CFDataGetBytePtr(data) else {
    fatalError("Couldn't access image data")
}
assert(cgImage.colorSpace?.model == .rgb)

let bytesPerPixel = cgImage.bitsPerPixel / cgImage.bitsPerComponent
for y in 0 ..< cgImage.height {
    for x in 0 ..< cgImage.width {
        let offset = (y * cgImage.bytesPerRow) + (x * bytesPerPixel)
        let components = (r: bytes[offset], g: bytes[offset + 1], b: bytes[offset + 2])
        print("[x:\(x), y:\(y)] \(components)")
    }
    print("---")
}

Works for me just fine.

If you want to know how much numbers the array have, you want to know the array length. The function sizeof(var) in C gives you the bytes in the computer memory. So if you know the memory the int occupy you can do like this:

int arraylength(int array[]) {
    return sizeof(array) / sizeof(int); // Size of the Array divided by the int size
}

I used a hybrid approach to get around the newline thing by using tr to replace newlines with tabs, then replacing tabs with whatever I want. In this case, "
" since I'm trying to generate HTML breaks.

echo -e "a\nb\nc\n" |tr '\n' '\t' | sed 's/\t/ <br> /g'`

asyncio.sleep

Notice in recent Python versions (Python 3.4 or higher) you can use asyncio.sleep. It's related to asynchronous programming and asyncio. Check out next example:

import asyncio
from datetime import datetime

@asyncio.coroutine
def countdown(iteration_name, countdown_sec):
    """
    Just count for some countdown_sec seconds and do nothing else
    """
    while countdown_sec > 0:
       print(f'{iteration_name} iterates: {countdown_sec} seconds')
       yield from asyncio.sleep(1)
       countdown_sec -= 1

loop = asyncio.get_event_loop()
tasks = [asyncio.ensure_future(countdown('First Count', 2)),
         asyncio.ensure_future(countdown('Second Count', 3))]

start_time = datetime.utcnow()

# Run both methods. How much time will both run...?
loop.run_until_complete(asyncio.wait(tasks))

loop.close()

print(f'total running time: {datetime.utcnow() - start_time}')

We may think it will "sleep" for 2 seconds for first method and then 3 seconds in the second method, a total of 5 seconds running time of this code. But it will print:

total_running_time: 0:00:03.01286

It is recommended to read asyncio official documentation for more details.

Named tuples are basically easy-to-create, lightweight object types. Named tuple instances can be referenced using object-like variable dereferencing or the standard tuple syntax. They can be used similarly to struct or other common record types, except that they are immutable. They were added in Python 2.6 and Python 3.0, although there is a recipe for implementation in Python 2.4.

For example, it is common to represent a point as a tuple (x, y). This leads to code like the following:

pt1 = (1.0, 5.0)
pt2 = (2.5, 1.5)

from math import sqrt
line_length = sqrt((pt1[0]-pt2[0])**2 + (pt1[1]-pt2[1])**2)

Using a named tuple it becomes more readable:

from collections import namedtuple
Point = namedtuple('Point', 'x y')
pt1 = Point(1.0, 5.0)
pt2 = Point(2.5, 1.5)

from math import sqrt
line_length = sqrt((pt1.x-pt2.x)**2 + (pt1.y-pt2.y)**2)

However, named tuples are still backwards compatible with normal tuples, so the following will still work:

Point = namedtuple('Point', 'x y')
pt1 = Point(1.0, 5.0)
pt2 = Point(2.5, 1.5)

from math import sqrt
# use index referencing
line_length = sqrt((pt1[0]-pt2[0])**2 + (pt1[1]-pt2[1])**2)
 # use tuple unpacking
x1, y1 = pt1

Thus, you should use named tuples instead of tuples anywhere you think object notation will make your code more pythonic and more easily readable. I personally have started using them to represent very simple value types, particularly when passing them as parameters to functions. It makes the functions more readable, without seeing the context of the tuple packing.

Furthermore, you can also replace ordinary immutable classes that have no functions, only fields with them. You can even use your named tuple types as base classes:

class Point(namedtuple('Point', 'x y')):
    [...]

However, as with tuples, attributes in named tuples are immutable:

>>> Point = namedtuple('Point', 'x y')
>>> pt1 = Point(1.0, 5.0)
>>> pt1.x = 2.0
AttributeError: can't set attribute

If you want to be able change the values, you need another type. There is a handy recipe for mutable recordtypes which allow you to set new values to attributes.

>>> from rcdtype import *
>>> Point = recordtype('Point', 'x y')
>>> pt1 = Point(1.0, 5.0)
>>> pt1 = Point(1.0, 5.0)
>>> pt1.x = 2.0
>>> print(pt1[0])
    2.0

I am not aware of any form of "named list" that lets you add new fields, however. You may just want to use a dictionary in this situation. Named tuples can be converted to dictionaries using pt1._asdict() which returns {'x': 1.0, 'y': 5.0} and can be operated upon with all the usual dictionary functions.

As already noted, you should check the documentation for more information from which these examples were constructed.

You can use json.loads:

import json
import requests

response = requests.get(...)
json_data = json.loads(response.text)

This converts a given string into a dictionary which allows you to access your JSON data easily within your code.

Or you can use @Martijn's helpful suggestion, and the higher voted answer, response.json().

In Java 9 the version 1 should be faster because it is converted to invokedynamic call. More details can be found in JEP-280:

The idea is to replace the entire StringBuilder append dance with a simple invokedynamic call to java.lang.invoke.StringConcatFactory, that will accept the values in the need of concatenation.

For NetBeans to be able to interact with tomcat, it needs the user as setup in netbeans to be properly configured in the tomcat-users.xml file. NetBeans can do so automatically.

That is, within the tomcat-users.xml, which you can find in ${CATALINA_HOME}/conf, or ${CATALINA_BASE}/conf,

1. make sure that the user (as chosen in netbeans) is added the script-manager role

Example, change

<user password="tomcat" roles="manager,admin" username="tomcat"/>

To

<user password="tomcat" roles="manager-script,manager,admin" username="tomcat"/>

2. make sure that the manager-script role is declared

Add

<role rolename="manager-script"/>

Actually the netbeans online-help incorrectly states:

Username - Specifies the user name that the IDE uses to log into the server's manager application. The user must be associated with the manager role. The first time the IDE started the Tomcat Web Server, such as through the Start/Stop menu action or by executing a web component from the IDE, the IDE adds an admin user with a randomly-generated password to the tomcat-base-path/conf/tomcat-users.xml file. (Right-click the Tomcat Web server instance node in the Services window and select Properties. In the Properties dialog box, the Base Directory property points to the base-dir directory.) The admin user entry in the tomcat-users.xml file looks similar to the following: <user username="idea" password="woiehh" roles="manager"/>

The role should be manager-script, and not manager.

For a more complete tomcat-users.xml file:

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
  <role rolename="manager-script"/>
  <role rolename="manager-gui"/>
  <user password="tomcat" roles="manager-script" username="tomcat"/>
  <user password="pass" roles="manager-gui" username="me"/>
</tomcat-users>

There is another nice posting on why am I getting the deployment error?

from within the git bash shell type:

>cd /bin
>ls -l

You will then see a long listing of all the unix-like commands available. There are lots of goodies in there.

You can simply handle the NO_DATA_FOUND exception by setting your variable to NULL. This way, only one query is required.

    v_column my_table.column%TYPE;

BEGIN

    BEGIN
      select column into v_column from my_table where ...;
    EXCEPTION
      WHEN NO_DATA_FOUND THEN
        v_column := NULL;
    END;

    ... use v_column here
END;

scrollHeight is a regular javascript property so you don't need jQuery.

var test = document.getElementById("foo").scrollHeight;

From SonarLint, if you already have the path, use path.toFile().exists() instead of Files.exists for better performance.

The Files.exists method has noticeably poor performance in JDK 8, and can slow an application significantly when used to check files that don't actually exist.

The same goes for Files.notExists, Files.isDirectory and Files.isRegularFile.

Noncompliant Code Example:

Path myPath;
if(java.nio.Files.exists(myPath)) {  // Noncompliant
    // do something
}

Compliant Solution:

Path myPath;
if(myPath.toFile().exists())) {
    // do something
}

The best i can do for both iOS7 and less is:

- (CGRect)placeholderRectForBounds:(CGRect)bounds {
  return [self textRectForBounds:bounds];
}

- (CGRect)editingRectForBounds:(CGRect)bounds {
  return [self textRectForBounds:bounds];
}

- (CGRect)textRectForBounds:(CGRect)bounds {
  CGRect rect = CGRectInset(bounds, 0, 6); //TODO: can be improved by comparing font size versus bounds.size.height
  return rect;
}

- (void)drawPlaceholderInRect:(CGRect)rect {
  UIColor *color =RGBColor(65, 65, 65);
  if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) {
    [self.placeholder drawInRect:rect withAttributes:@{NSFontAttributeName:self.font, UITextAttributeTextColor:color}];
  } else {
    [color setFill];
    [self.placeholder drawInRect:rect withFont:self.font];
  }
}

You can use str.format(), too:

>>> print "financial return of outcome 1 = {:.2f}".format(1.23456)
financial return of outcome 1 = 1.23

Use .net inbuilt class JavaScriptSerializer

  JavaScriptSerializer js = new JavaScriptSerializer();
  string json = js.Serialize(obj);

Try Access DataTable easiest way which can help you for getting perfect idea for accessing DataTable, DataSet using Linq...

Consider following example, suppose we have DataTable like below.

DataTable ObjDt = new DataTable("List");
ObjDt.Columns.Add("WorkName", typeof(string));
ObjDt.Columns.Add("Price", typeof(decimal));
ObjDt.Columns.Add("Area", typeof(string));
ObjDt.Columns.Add("Quantity",typeof(int));
ObjDt.Columns.Add("Breath",typeof(decimal));
ObjDt.Columns.Add("Length",typeof(decimal));

Here above is the code for DatTable, here we assume that there are some data are available in this DataTable, and we have to bind Grid view of particular by processing some data as shown below.

Area | Quantity | Breath | Length | Price = Quantity * breath *Length

Than we have to fire following query which will give us exact result as we want.

var data = ObjDt.AsEnumerable().Select
            (r => new
            {
                Area = r.Field<string>("Area"),
                Que = r.Field<int>("Quantity"),
                Breath = r.Field<decimal>("Breath"),
                Length = r.Field<decimal>("Length"),
                totLen = r.Field<int>("Quantity") * (r.Field<decimal>("Breath") * r.Field<decimal>("Length"))
            }).ToList();

We just have to assign this data variable as Data Source.

By using this simple Linq query we can get all our accepts, and also we can perform all other LINQ queries with this…

You can do it the DOM way as well:

var div = document.getElementById('cart_item');
while(div.firstChild){
    div.removeChild(div.firstChild);
}

save the array from explode() to a variable, and then call end() on this variable:

$tmp = explode('.', $file_name);
$file_extension = end($tmp);

btw: I use this code to get the file extension:

$ext = substr( strrchr($file_name, '.'), 1);

where strrchr extracts the string after the last . and substr cuts off the .

At least for the Windows binary version I tested, (the Generic Win64 no-SSL binary, currently based on 7.33.0), you are subject to limitations in how the command line arguments are being parsed. The answer by xmas describes the correct syntax in that setting, which also works in a batch file. Using the example provided:

curl -i -X POST -H "Content-Type: application/json" -d "{""data1"":""data goes here"",""data2"":""data2 goes here""}" http:localhost/path/to/api

A cleaner alternative to avoid having to deal with escaped characters, which is dependent upon whatever library is used to parse the command line, is to have your standard json format text in a separate file:

curl -i -X POST -H "Content-Type: application/json" -d "@body.json" http:localhost/path/to/api

You can use offsets to make a column appear centered, just use an offset equal to half of the remaining size of the row, in your case I would suggest using col-lg-4 with col-lg-offset-4, that's (12-4)/2.

<div class="row">
    <div class="col-lg-4 col-lg-offset-4">
        <div class="input-group">
            <input type="text" class="form-control" /> 
            <span class="input-group-btn">
                <button class="btn btn-default" type="button">Go!</button>
            </span>
        </div><!-- /input-group -->
    </div><!-- /.col-lg-4 -->
</div><!-- /.row -->

Demo fiddle

Note that this technique only works for even column sizes (.col-X-2, .col-X-4, col-X-6, etc...), if you want to support any size you can use margin: 0 auto; but you need to remove the float from the element too, I recommend a custom CSS class like the following:

.col-centered{
    margin: 0 auto;
    float: none;
}

Demo fiddle

You can also add an Image to the Media Gallery by intent, have a look at the example code to see how it is done:

ContentValues image = new ContentValues();

image.put(Images.Media.TITLE, imageTitle);
image.put(Images.Media.DISPLAY_NAME, imageDisplayName);
image.put(Images.Media.DESCRIPTION, imageDescription);
image.put(Images.Media.DATE_ADDED, dateTaken);
image.put(Images.Media.DATE_TAKEN, dateTaken);
image.put(Images.Media.DATE_MODIFIED, dateTaken);
image.put(Images.Media.MIME_TYPE, "image/png");
image.put(Images.Media.ORIENTATION, 0);

 File parent = imageFile.getParentFile();
 String path = parent.toString().toLowerCase();
 String name = parent.getName().toLowerCase();
 image.put(Images.ImageColumns.BUCKET_ID, path.hashCode());
 image.put(Images.ImageColumns.BUCKET_DISPLAY_NAME, name);
 image.put(Images.Media.SIZE, imageFile.length());

 image.put(Images.Media.DATA, imageFile.getAbsolutePath());

 Uri result = context.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, image);

If you are using Resharper make sure it does not add the wrong header for you, very common cases with ReSharper are:

• #include <consoleapi2.h
  
• #include <apiquery2.h>
• #include <fileapi.h>

UPDATE:
Another suggestion is to check if you are including a "partial Windows.h", what I mean is that if you include for example winbase.h or minwindef.h you may end up with that error, add "the big" Windows.h instead. There are also some less obvious cases that I went through, the most notable was when I only included synchapi.h, the docs clearly state that is the header to be included for some functions like AcquireSRWLockShared but it triggered the No target architecture, the fix was to remove the synchapi.h and include "the big" Windows.h.

The Windows.h is huge, it defines macros(many of them remove the No target arch error) and includes many other headers. In summary, always check if you are including some header that could be replaced by Windows.h because it is not unusual to include a header that relies on some constants that are defined by Windows.h, so if you fail to include this header your compilation may fail.

Use data type 'MultilineText':

[DataType(DataType.MultilineText)]
public string Text { get; set; }

See ASP.NET MVC3 - textarea with @Html.EditorFor

r = read mode only
r+ = read/write mode
w = write mode only
w+ = read/write mode, if the file already exists override it (empty it)

So yes, if the file already exists w+ will erase the file and give you an empty file.

I'm using XML to carry the result back from the php on the server to the webpage and I have had the same behaviour.

In my case the reason was , that the closing tag did not match the opening tag.

<?php
....
header("Content-Type: text/xml");
echo "<?xml version=\"1.0\" encoding=\"utf-8\"?>
    <result>
        <status>$status</status>
        <OPENING_TAG>$message</CLOSING_TAG>
    </result>";
?>

The method len() returns the number of elements in the list.

 list1, list2 = [123, 'xyz', 'zara'], [456, 'abc']
    print "First list length : ", len(list1)
    print "Second list length : ", len(list2)

When we run above program, it produces the following result -

First list length : 3 Second list length : 2

You should use POST if there is a lot of data, or sort-of sensitive information (really sensitive stuff needs a secure connection as well).

Use GET if you want people to be able to bookmark your page, because all the data is included with the bookmark.

Just be careful of people hitting REFRESH with the GET method, because the data will be sent again every time without warning the user (POST sometimes warns the user about resending data).

If the data is stored as INT, you may want to try

Average = (R1 + R2 + R3 + R4 + R5) / 5.0

The answer provided by Joe Stefanelli is already correct.

SELECT name FROM (SELECT name FROM agentinformation) as a  

We need to make an alias of the subquery because a query needs a table object which we will get from making an alias for the subquery. Conceptually, the subquery results are substituted into the outer query. As we need a table object in the outer query, we need to make an alias of the inner query.

Statements that include a subquery usually take one of these forms:

• WHERE expression [NOT] IN (subquery)
• WHERE expression comparison_operator [ANY | ALL] (subquery)
• WHERE [NOT] EXISTS (subquery)

Check for more subquery rules and subquery types.

More examples of Nested Subqueries.

1. IN / NOT IN – This operator takes the output of the inner query after the inner query gets executed which can be zero or more values and sends it to the outer query. The outer query then fetches all the matching [IN operator] or non matching [NOT IN operator] rows.

2. ANY – [>ANY or ANY operator takes the list of values produced by the inner query and fetches all the values which are greater than the minimum value of the list. The

e.g. >ANY(100,200,300), the ANY operator will fetch all the values greater than 100.

3. ALL – [>ALL or ALL operator takes the list of values produced by the inner query and fetches all the values which are greater than the maximum of the list. The

e.g. >ALL(100,200,300), the ALL operator will fetch all the values greater than 300.

4. EXISTS – The EXISTS keyword produces a Boolean value [TRUE/FALSE]. This EXISTS checks the existence of the rows returned by the sub query.

Try to use sudo, to run asterisk -r that works for me every time this error comes up.

The disabled attribute's standard behavior only happens for form elements. Try unbinding the event:

$("span").unbind("click");

Just try encodeURI() and encodeURIComponent() yourself...

console.log(encodeURIComponent('@#$%^&*'));

Input: @#$%^&*. Output: %40%23%24%25%5E%26*. So, wait, what happened to *? Why wasn't this converted? TLDR: You actually want fixedEncodeURIComponent() and fixedEncodeURI(). Long-story...

You should not be using encodeURIComponent() or encodeURI(). You should use fixedEncodeURIComponent() and fixedEncodeURI(), according to the MDN Documentation.

Regarding encodeURI()...

If one wishes to follow the more recent RFC3986 for URLs, which makes square brackets reserved (for IPv6) and thus not encoded when forming something which could be part of a URL (such as a host), the following code snippet may help:

function fixedEncodeURI(str) { return encodeURI(str).replace(/%5B/g, '[').replace(/%5D/g, ']'); }

Regarding encodeURIComponent()...

To be more stringent in adhering to RFC 3986 (which reserves !, ', (, ), and *), even though these characters have no formalized URI delimiting uses, the following can be safely used:

function fixedEncodeURIComponent(str) { return encodeURIComponent(str).replace(/[!'()*]/g, function(c) { return '%' + c.charCodeAt(0).toString(16); }); }

So, what is the difference? fixedEncodeURI() and fixedEncodeURIComponent() convert the same set of values, but fixedEncodeURIComponent() also converts this set: +@?=:*#;,$&. This set is used in GET parameters (&, +, etc.), anchor tags (#), wildcard tags (*), email/username parts (@), etc..

For example -- If you use encodeURI(), [email protected]/?email=me@home will not properly send the second @ to the server, except for your browser handling the compatibility (as Chrome naturally does often).

Another way of doing this would be using Aggregation. You should be able to achieve a similar result using a single query. Such as this:

Item.objects.values("contest").annotate(Count("id"))

I did not test this specific query, but this should output a count of the items for each value in contests as a dictionary.

Try multiple-select, especially multiple-items. Looks to be much clean and managed solution, with tons of examples. You can also view the source.

Unfortunately, when it comes to EDMs (Electronic Direct Mail), Outlook is your worst enemy. Some versions don't respect padding when a cell's content dictates the cell dimensions.

The approach that'll give you the most consistent result across mail clients is to use empty table cells as padding (I know, the horror), but remember to fill those tables with a blank image of the desired dimensions because, you guessed it, some versions of Outlook don't respect height/width declarations of empty cells.

Aren't EDMs fun? (No. They are not.)

If you don't mind the boolean being converted to a number (that is either 0 or 1), you can use the Bitwise XOR Assignment Operator. Like so:

bool ^= true;   //- toggle value.

This is especially good if you use long, descriptive boolean names, EG:

var inDynamicEditMode   = true;     // Value is: true (boolean)
inDynamicEditMode      ^= true;     // Value is: 0 (number)
inDynamicEditMode      ^= true;     // Value is: 1 (number)
inDynamicEditMode      ^= true;     // Value is: 0 (number)

This is easier for me to scan than repeating the variable in each line.

This method works in all (major) browsers (and most programming languages).

If you want to test the logic just don´t test it asynchronously.

For example to test this code which works on results of an asynchronous method.

public class Example {
    private Dependency dependency;

    public Example(Dependency dependency) {
        this.dependency = dependency;            
    }

    public CompletableFuture<String> someAsyncMethod(){
        return dependency.asyncMethod()
                .handle((r,ex) -> {
                    if(ex != null) {
                        return "got exception";
                    } else {
                        return r.toString();
                    }
                });
    }
}

public class Dependency {
    public CompletableFuture<Integer> asyncMethod() {
        // do some async stuff       
    }
}

In the test mock the dependency with synchronous implementation. The unit test is completely synchronous and runs in 150ms.

public class DependencyTest {
    private Example sut;
    private Dependency dependency;

    public void setup() {
        dependency = Mockito.mock(Dependency.class);;
        sut = new Example(dependency);
    }

    @Test public void success() throws InterruptedException, ExecutionException {
        when(dependency.asyncMethod()).thenReturn(CompletableFuture.completedFuture(5));

        // When
        CompletableFuture<String> result = sut.someAsyncMethod();

        // Then
        assertThat(result.isCompletedExceptionally(), is(equalTo(false)));
        String value = result.get();
        assertThat(value, is(equalTo("5")));
    }

    @Test public void failed() throws InterruptedException, ExecutionException {
        // Given
        CompletableFuture<Integer> c = new CompletableFuture<Integer>();
        c.completeExceptionally(new RuntimeException("failed"));
        when(dependency.asyncMethod()).thenReturn(c);

        // When
        CompletableFuture<String> result = sut.someAsyncMethod();

        // Then
        assertThat(result.isCompletedExceptionally(), is(equalTo(false)));
        String value = result.get();
        assertThat(value, is(equalTo("got exception")));
    }
}

You don´t test the async behaviour but you can test if the logic is correct.

If every input asks the same question, you should use a for loop and an array of inputs:

Scanner dd = new Scanner(System.in);
int[] vars = new int[3];

for(int i = 0; i < vars.length; i++) {
  System.out.println("Enter next var: ");
  vars[i] = dd.nextInt();
}

Or as Chip suggested, you can parse the input from one line:

Scanner in = new Scanner(System.in);
int[] vars = new int[3];

System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
  vars[i] = in.nextInt();

You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.

The SpeechRecognition library requires Python 3.3 or up:

Requirements

[...]

The first software requirement is Python 3.3 or better. This is required to use the library.

and from the Trove classifiers:

Programming Language :: Python
Programming Language :: Python :: 3
Programming Language :: Python :: 3.3
Programming Language :: Python :: 3.4

The urllib.request module is part of the Python 3 standard library; in Python 2 you'd use urllib2 here.

The END comes from the pager used to display the log (your are at that moment still inside it). Type q to exit it.

In your broadcast receiver you could access a view via inflation a root layout from XML resource and then find all your views from this root layout with findViewByid():

View view = View.inflate(context, R.layout.ROOT_LAYOUT, null);

Now you can access your views via 'view' and cast them to your view type:

myImage = (ImageView) view.findViewById(R.id.my_image);

This option was introduced in order to remove the need to deploy very large PIAs (Primary Interop Assemblies) for interop.

It simply embeds the managed bridging code used that allows you to talk to unmanaged assemblies, but instead of embedding it all it only creates the stuff you actually use in code.

Read more in Scott Hanselman's blog post about it and other VS improvements here.

As for whether it is advised or not, I'm not sure as I don't need to use this feature. A quick web search yields a few leads:

• Check your Embed Interop Types flag when doing Visual Studio extensibility work
• The Pain of deploying Primary Interop Assemblies

The only risk of turning them all to false is more deployment concerns with PIA files and a larger deployment if some of those files are large.

As he stated, used the ImageButton widget. Copy your image file within the Res/drawable/ directory of your project. While in XML simply go into the graphic representation (for simplicity) of your XML file and click on your ImageButton widget that you added, go to its properties sheet and click on the [...] in the src: field. Simply navigate to your image file. Also, make sure you're using a proper format; I tend to stick with .png files for my own reasons, but they work.

Programmatically in Swift 5 with Xcode 10.2

Building on top of @La masse's solution, but using autolayout to support rotation

Set anchors for the view's position (left, top, centerY, centerX, etc). You can also set the width anchor or set the frame.width dynamically with the UIScreen extension provided (to support rotation)

label = UILabel()
label.numberOfLines = 0
label.lineBreakMode = .byWordWrapping
self.view.addSubview(label)
// SET AUTOLAYOUT ANCHORS
label.translatesAutoresizingMaskIntoConstraints = false
label.leftAnchor.constraint(equalTo: self.view.leftAnchor, constant: 20).isActive = true
label.rightAnchor.constraint(equalTo: self.view.rightAnchor, constant: -20).isActive = true
label.topAnchor.constraint(equalTo: self.view.topAnchor, constant: 20).isActive = true
// OPTIONALLY, YOU CAN USE THIS INSTEAD OF THE WIDTH ANCHOR (OR LEFT/RIGHT)
// label.frame.size = CGSize(width: UIScreen.absoluteWidth() - 40.0, height: 0)
label.text = "YOUR LONG TEXT GOES HERE"
label.sizeToFit()

If setting frame.width dynamically using UIScreen:

extension UIScreen {   // OPTIONAL IF USING A DYNAMIC FRAME WIDTH
    class func absoluteWidth() -> CGFloat {
        var width: CGFloat
        if UIScreen.main.bounds.width > UIScreen.main.bounds.height {
            width = self.main.bounds.height // Landscape
        } else {
            width = self.main.bounds.width // Portrait
        }
        return width
    }
}

@amal. This code will match your requirement. Only letter and space in between will be allow, no number. The text begin with any letter and could have space in between only. "^" denotes the beginning of the line and "$" denotes end of the line.

public static boolean validateLetters(String txt) {

    String regx = "^[a-zA-Z ]+$";
    Pattern pattern = Pattern.compile(regx,Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(txt);
    return matcher.find();

}

Try with below code sample.it is working for me

var date_input_field = $('input[name="date"]');
    date_input_field .datepicker({
        dateFormat: '/dd/mm/yyyy',
        container: container,
        todayHighlight: true,
        autoclose: true,
    }).on('change', function(selected){
        alert("startDate..."+selected.timeStamp);
    });

Use the css "rotate()" method:

div {
  width: 100px;
  height: 100px;
  background-color: yellow;
  border: 1px solid black;
}

div#rotate{
  transform: rotate(90deg);
}

<div>
normal div
</div>
<br>

<div id="rotate">
This div is rotated 90 degrees
</div>

Summary from Angular docs:

• There are five recipe types that define how to create objects: Value, Factory, Service, Provider and Constant.
• Factory and Service are the most commonly used recipes. The only difference between them is that the Service recipe works better for objects of a custom type, while the Factory can produce JavaScript primitives and functions.
• The Provider recipe is the core recipe type and all the other ones are just syntactic sugar on it.
• Provider is the most complex recipe type. You don't need it unless you are building a reusable piece of code that needs global configuration.

You can also use the AddRange method

listBox1.Items.AddRange(myList.ToArray());

I use this small extension in Swift 5, which keeps it simple and easy to check for any object that is member of UIView.

extension UIView {
    var isVisible: Bool {
        guard let _ = self.window else {
            return false
        }
        return true
    }
}

Then, I just use it as a simple if statement check...

if myView.isVisible {
    // do something
}

I hope it helps! :)

The simplest method to escape and insert:

global $connection;
$columns = implode(", ",array_keys($array_data));
$func = function($value) {
    global $connection;
    return mysqli_real_escape_string($connection, $value);
};
$escaped_values = array_map($func, array_values($array_data));
$values  = implode(", ", $escaped_values);
$result = mysqli_query($connection, "INSERT INTO $table_name ($columns) VALUES ($values)");

string inLine = reader.ReadToEnd();
myList = inLine.Split(new string[] { "\r\n" }, StringSplitOptions.None).ToList();

This answer misses the original point, which was that they were getting an OutOfMemory error. If you proceed with the above version, you are sure to hit it if your system does not have the appropriate CONTIGUOUS available ram to load the file.

You simply must break it into parts, and either store as List or String[] either way.

I know this was asked awhile back, but I found a comprehensive list of the virtual keyboard key codes right in MSDN, for use in C/C++. This also includes the mouse events. Note it is different than the javascript key codes (I noticed it around the VK_OEM section).

The problem can be seen when checking the remote.origin.fetch setting
(The lines starting with $ are bash prompts with the commands I typed. The other lines are the resulting output)

$ git config --get remote.origin.fetch
+refs/heads/master:refs/remotes/origin/master

As you can see, in my case, the remote was set to fetch the master branch specifically and only. I fixed it as per below, including the second command to check the results.

$ git config remote.origin.fetch "+refs/heads/*:refs/remotes/origin/*"
$ git config --get remote.origin.fetch
+refs/heads/*:refs/remotes/origin/*

The wildcard * of course means everything under that path.

Unfortunately I saw this comment after I had already dug through and found the answer by trial and error.

First of all, the easiest way to run things at startup is to add them to the file /etc/rc.local.

Another simple way is to use @reboot in your crontab. Read the cron manpage for details.

However, if you want to do things properly, in addition to adding a script to /etc/init.d you need to tell ubuntu when the script should be run and with what parameters. This is done with the command update-rc.d which creates a symlink from some of the /etc/rc* directories to your script. So, you'd need to do something like:

update-rc.d yourscriptname start 2

However, real init scripts should be able to handle a variety of command line options and otherwise integrate to the startup process. The file /etc/init.d/README has some details and further pointers.

The following query i have used in sql-server 2008, it may be help you.

Now I need to connect that application from my local computer, but I don't know the JMX port number of the remote computer. Where can I find it? Or, must I restart that application with some VM parameters to specify the port number?

By default JMX does not publish on a port unless you specify the arguments from this page: How to activate JMX...

-Dcom.sun.management.jmxremote # no longer required for JDK6
-Dcom.sun.management.jmxremote.port=9010
-Dcom.sun.management.jmxremote.local.only=false # careful with security implications
-Dcom.sun.management.jmxremote.authenticate=false # careful with security implications

If you are running you should be able to access any of those system properties to see if they have been set:

if (System.getProperty("com.sun.management.jmxremote") == null) {
    System.out.println("JMX remote is disabled");
} else [
    String portString = System.getProperty("com.sun.management.jmxremote.port");
    if (portString != null) {
        System.out.println("JMX running on port "
            + Integer.parseInt(portString));
    }
}

Depending on how the server is connected, you might also have to specify the following parameter. As part of the initial JMX connection, jconsole connects up to the RMI port to determine which port the JMX server is running on. When you initially start up a JMX enabled application, it looks its own hostname to determine what address to return in that initial RMI transaction. If your hostname is not in /etc/hosts or if it is set to an incorrect interface address then you can override it with the following:

-Djava.rmi.server.hostname=<IP address>

As an aside, my SimpleJMX package allows you to define both the JMX server and the RMI port or set them both to the same port. The above port defined with com.sun.management.jmxremote.port is actually the RMI port. This tells the client what port the JMX server is running on.

Just simply use:

var update_pizza = function () {
     $("#pizza_kind").prop("disabled", !$('#pizza').prop('checked'));
};

update_pizza();
$("#pizza").change(update_pizza);

DEMO ?

For people who are reading byte array into String and trying to convert to object with JAXB, you can add "iso-8859-1" encoding by creating String from byte array like this:

String JAXBallowedString= new String(byte[] input, "iso-8859-1");

This would replace the conflicting byte to single-byte encoding which JAXB can handle. Obviously this solution is only to parse the xml.

Once you are able to parse those strings into a Date object comparing them is easy (Using the < operator). Parsing the dates will depend on the format. You may take a look at Datejs which might simplify this task.

Add your library folder in your root location of your project and copy all the library files there. For ex YourProject/library then sync it and rest things seems OK to me.

Unfortunately PL/SQL doesn't have IF EXISTS operator like SQL Server. But you can do something like this:

begin
  for x in ( select count(*) cnt
               from dual 
              where exists (
                select 1 from courseoffering co
                  join co_enrolment ce on ce.co_id = co.co_id
                 where ce.s_regno = 403 
                   and ce.coe_completionstatus = 'C' 
                   and co.c_id = 803 ) )
  loop
        if ( x.cnt = 1 ) 
        then
           dbms_output.put_line('exists');
        else 
           dbms_output.put_line('does not exist');
        end if;
  end loop;
end;

Simply try this code

A quick answer:

mvn -fn test

Works with nested project builds.

Here is what I use when I don't have access to the source string, e.g. for downloaded HTML:

// replace newlines with <br>
public static String replaceNewlinesWithBreaks(String source) {
    return source != null ? source.replaceAll("(?:\n|\r\n)","<br>") : "";
}

For XML you should probably edit that to replace with <br/> instead.

Example of its use in a function (additional calls removed for clarity):

// remove HTML tags but preserve supported HTML text styling (if there is any)
public static CharSequence getStyledTextFromHtml(String source) {
    return android.text.Html.fromHtml(replaceNewlinesWithBreaks(source));
}

...and a further example:

textView.setText(getStyledTextFromHtml(someString));

In general, I use nohup CMD & to run a nohup background process. However, when the command is in a form that nohup won't accept then I run it through bash -c "...".

For example:

nohup bash -c "(time ./script arg1 arg2 > script.out) &> time_n_err.out" &

stdout from the script gets written to script.out, while stderr and the output of time goes into time_n_err.out.

So, in your case:

nohup bash -c "(time bash executeScript 1 input fileOutput > scrOutput) &> timeUse.txt" &

try using form collection

<input id="responsable" value="True" name="checkResp" type="checkbox" /> 

[HttpPost]
public ActionResult Index(FormCollection collection)
{
     if(!string.IsNullOrEmpty(collection["checkResp"])
     {
        string checkResp=collection["checkResp"];
        bool checkRespB=Convert.ToBoolean(checkResp);
     }

}

There seem to be multiple causes for this.

For mine, it was that the .csproj file contained references to two different versions of Microsoft.Bcl.Build.targets:

I removed the old reference, and it solved the problem.

Replace [True | False (default)]

Effect

1.  Replace the directive element. 

Dependency:

1. When replace: true, the template or templateUrl must be required. 

I've not found anything in the API, but one thing you could do is attach an event handler to the standard paginator and detect if it has changed:

$('.dataTables_length select').live('change', function(){

You can easily change the match-type to 1 when you are looking for the greatest value or to -1 when looking for the smallest value.

You have to explicitly define the constructor in B and explicitly call the constructor for the parent.

B(int x) : A(x) { }

or

B() : A(5) { }

    }

        for(double a : data)
            sum += a;
        return sum/size;
    }

    double getVariance() {
        double mean = getMean();
        double temp = 0;
        for(double a :data)
            temp += (a-mean)*(a-mean);
        return temp/(size-1);
    }

    double getStdDev() {
        return Math.sqrt(getVariance());
    }

    public double median() {
       Arrays.sort(data);
       if (data.length % 2 == 0)
          return (data[(data.length / 2) - 1] + data[data.length / 2]) / 2.0;

ADD this single line code in your App Delegate - Did Finish Lauch. It will change Font, color of navigation bar throughout the application.

UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white, NSAttributedString.Key.font: UIFont(name: "YOUR FONT NAME", size: 25.0)!]

Bootstrap has 3 lines of CSS, within your bootstrap.css generated file that control the placeholder text color:

.form-control::-moz-placeholder {
  color: #999999;
  opacity: 1;
}
.form-control:-ms-input-placeholder {
  color: #999999;
}
.form-control::-webkit-input-placeholder {
  color: #999999;
}

Now if you add this to your own CSS file it won't override bootstrap's because it is less specific. So assmuning your form inside a then add that to your CSS:

form .form-control::-moz-placeholder {
  color: #fff;
  opacity: 1;
}
form .form-control:-ms-input-placeholder {
  color: #fff;
}
form .form-control::-webkit-input-placeholder {
  color: #fff;
}

Voila that will override bootstrap's CSS.

the bast way i use i bind the textblock and combobox to same property and this property should support notifyPropertyChanged.

i used relativeresource to bind to parent view datacontext which is usercontrol to go up datagrid level in binding because in this case the datagrid will search in object that you used in datagrid.itemsource

<DataGridTemplateColumn Header="your_columnName">
     <DataGridTemplateColumn.CellTemplate>
          <DataTemplate>
             <TextBlock Text="{Binding RelativeSource={RelativeSource AncestorType={x:Type UserControl}}, Path=DataContext.SelectedUnit.Name, Mode=TwoWay}" />
           </DataTemplate>
     </DataGridTemplateColumn.CellTemplate>
     <DataGridTemplateColumn.CellEditingTemplate>
           <DataTemplate>
            <ComboBox DisplayMemberPath="Name"
                      IsEditable="True"
                      ItemsSource="{Binding RelativeSource={RelativeSource AncestorType={x:Type UserControl}}, Path=DataContext.UnitLookupCollection}"
                       SelectedItem="{Binding RelativeSource={RelativeSource AncestorType={x:Type UserControl}}, Path=DataContext.SelectedUnit, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                      SelectedValue="{Binding UnitId, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                      SelectedValuePath="Id" />
            </DataTemplate>
    </DataGridTemplateColumn.CellEditingTemplate>
</DataGridTemplateColumn>

In IntelliJ Idea 2017.1 you can use the embedded SVN client that sadly is not enabled by default. Here's how you can activate it.

1) Open IntelliJ Idea

2) Menu Help > Find Actions...

3) Type subversion to gain access to the subversion related settings. Choose the item Subversion Settings as highlighted in the following picture.

4) Finally, be sure to uncheck the option Use command line client.

From now on, in the current project, you'll use the embedded subversion.

I had a similar problem recently, and needed to change the permissions of my vendor folder

By running following commands :

1. php artisan cache:clear
2. chmod -R 777 storage vendor
3. composer dump-autoload

I need to give all the permissions required to open and write vendor files to solve this issue

You can do like this

sqlcmd -S <server Name> -U sa -P sapassword -i inputquery_file_name -o outputfile_name

From your command prompt run sqlcmd /? to get all the options you can use with sqlcmd utility

Never use =='NA' to test for missing values. Use is.na() instead. This should do it:

new_DF <- DF[rowSums(is.na(DF)) > 0,]

or in case you want to check a particular column, you can also use

new_DF <- DF[is.na(DF$Var),]

In case you have NA character values, first run

Df[Df=='NA'] <- NA

to replace them with missing values.

Because your update uses PUT method, {entryId: $scope.entryId} is considered as data, to tell angular generate from the PUT data, you need to add params: {entryId: '@entryId'} when you define your update, which means

return $resource('http://localhost\\:3000/realmen/:entryId', {}, {
  query: {method:'GET', params:{entryId:''}, isArray:true},
  post: {method:'POST'},
  update: {method:'PUT', params: {entryId: '@entryId'}},
  remove: {method:'DELETE'}
});

Fix: Was missing a closing curly brace on the update line.

As we were already using jQuery for a graphical eye-candy feature we ended up using this. A code like

$(document).ready(function() {
    // any code goes here
    init();
});

did everything we wanted and cares about browser incompatibilities at its own.

I use method 3 because it's the most understandable for others (whenever you see an <a> tag, you know it's a link) and when you are part of a team, you have to make simple things ;).

And finally I don't think it's useful and efficient to use JS simply to navigate to an other page.

There are in fact 3 questions in your question :

• Define frontend, middle and back end
• How and when do they overlap ?
• Their associated usual bottlenecks.

What JB King has described is correct, but it is a particular, simple version, where in fact he mapped front, middle and bacn to an MVC layer. He mapped M to the back, V to the front, and C to the middle.

For many people, it is just fine, since they come from the ugly world where even MVC was not applied, and you could have direct DB calls in a view.

However in real, complex web applications, you indeed have two or three different layers, called front, middle and back. Each of them may have an associated database and a controller.

The front-end will be visible by the end-user. It should not be confused with the front-office, which is the UI for parameters and administration of the front. The front-end will usually be some kind of CMS or e-commerce Platform (Magento, etc.)

The middle-end is not compulsory and is where the business logics is. It will be based on a PIM, a MDM tool, or some kind of custom database where you enrich your produts or your articles (for CMS). It'll also be the place where you code business functions that need to be shared between differents frontends (for instance between the PC frontend and the API-based mobile application). Sometimes, an ESB or tool like ActiveMQ will be your middle-end

The back-end will be a 3rd layer, surrouding your source database or your ERP. It may be jsut the API wrting to and reading from your ERP. It may be your supplier DB, if you are doing e-commerce. In fact, it really depends on web projects, but it is always a central repository. It'll be accessed either through a DB call, through an API, or an Hibernate layer, or a full-featured back-end application

This description means that answering the other 2 questions is not possible in this thread, as bottlenecks really depend on what your 3 ends contain : what JB King wrote remains true for simple MVC architectures

at the time the question was asked (5 years ago), maybe the MVC pattern was not yet so widely adopted. Now, there is absolutely no reason why the MVC pattern would not be followed and a view would be tied to DB calls. If you read the question "Are there cases where they MUST overlap, and frontend/backend cannot be separated?" in a broader sense, with 3 different components, then there times when the 3 layers architecture is useless of course. Think of a simple personal blog, you'll not need to pull external data or poll RabbitMQ queues.

Wrap your all statements in !IsPostBack condition on page load.

protected void Page_Load(object sender, EventArgs e)
{
   if(!IsPostBack)
   {
      // all statements
   }
}

This will fix your issue.

there are two ways to do this in jquery depending what you are looking for..

using jquery you can do

• //this will wait for the text assets to be loaded before calling this (the dom.. css.. js)

  $(document).ready(function(){...});
  

• //this will wait for all the images and text assets to finish loading before executing

  $(window).load(function(){...});
  

For Node.js there is Nodeclipse 0.2 with some bug fixes for chromedevtools

With docker compose there's a simple alternative (no need to create a Dockerfile). Just create a init-database.sh:

#!/bin/bash
set -e

psql -v ON_ERROR_STOP=1 --username "$POSTGRES_USER" --dbname "$POSTGRES_DB" <<-EOSQL
    CREATE USER docker;
    CREATE DATABASE my_project_development;
    GRANT ALL PRIVILEGES ON DATABASE my_project_development TO docker;
    CREATE DATABASE my_project_test;
    GRANT ALL PRIVILEGES ON DATABASE my_project_test TO docker;
EOSQL

And reference it in the volumes section:

version: '3.4'

services:
  postgres:
    image: postgres
    restart: unless-stopped
    volumes:
      - postgres:/var/lib/postgresql/data
      - ./init-database.sh:/docker-entrypoint-initdb.d/init-database.sh
    environment:
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=postgres
    ports:
      - 5432:5432

volumes:
  postgres:

Sorry but that's just much too much overhead (above), short and quick, if you have the MapFragment, you also have to map, just do the following:

if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
            googleMap.setMyLocationEnabled(true)
} else {
    // Show rationale and request permission.
}

Code is in Kotlin, hope you don't mind.

have fun

Btw I think this one is a duplicate of: Show Current Location inside Google Map Fragment

If, like me, what you usually want is to overwrite the contents of the working directory with that of the stashed files, and you still get a conflict, then what you want is to resolve the conflict using git checkout --theirs -- . from the root.

After that, you can git reset to bring all the changes from the index to the working directory, since apparently in case of conflict the changes to non-conflicted files stay in the index.

You may also want to run git stash drop [<stash name>] afterwards, to get rid of the stash, because git stash pop doesn't delete it in case of conflicts.

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|00D900",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(12, 18)
);

This is based off of Erik's answer from earlier, but I've found it easiest to read in the .csv file using pandas and then create a new instance of the class for every row in the in data frame.

This example is updated using iloc as pandas no longer uses ix in the most recent version. I don't know about Erik's situation but you need to create the list outside of the for loop otherwise it will not append to your array but simply overwrite it.

import pandas as pd
df = pd.read_csv('path_to_file', sep='delimiter')
products = []
for i in range(len(df)):
    products.append(
        Product(
        name=df.iloc[i][0]
        description=df.iloc[i][1]
        price=df.iloc[i][2]
        )
    )
Product.objects.bulk_create(products)

This is just breaking the DataFrame into an array of rows and then selecting each column out of that array off the zero index. (i.e. name is the first column, description the second, etc.)

Hope that helps.

Run below commands from app's home directory:

1. rake db:migrate:down VERSION="20140311142212" (here version is the timestamp prepended by rails when migration was created. This action will revert DB changes due to this migration)

2. Run "rails destroy migration migration_name" (migration_name is the one use chose while creating migration. Remove "timestamp_" from your migration file name to get it)

type in Terminal:

$ mvn --version

then get following result:

I've just set up a quick benchmarking exercise:

Function             time to run 1 million iterations
--------------------------------------------
(int) "123":                0.55029
intval("123"):              1.0115  (183%)

(int) "0":                  0.42461
intval("0"):                0.95683 (225%)

(int) int:                  0.1502
intval(int):                0.65716 (438%)

(int) array("a", "b"):      0.91264
intval(array("a", "b")):    1.47681 (162%)

(int) "hello":              0.42208
intval("hello"):            0.93678 (222%)

On average, calling intval() is two and a half times slower, and the difference is the greatest if your input already is an integer.

I'd be interested to know why though.

Update: I've run the tests again, this time with coercion (0 + $var)

| INPUT ($x)      |  (int) $x  |intval($x) |  0 + $x   |
|-----------------|------------|-----------|-----------|
| "123"           |   0.51541  |  0.96924  |  0.33828  |
| "0"             |   0.42723  |  0.97418  |  0.31353  |
| 123             |   0.15011  |  0.61690  |  0.15452  |
| array("a", "b") |   0.8893   |  1.45109  |  err!     |
| "hello"         |   0.42618  |  0.88803  |  0.1691   |
|-----------------|------------|-----------|-----------|

Addendum: I've just come across a slightly unexpected behaviour which you should be aware of when choosing one of these methods:

$x = "11";
(int) $x;      // int(11)
intval($x);    // int(11)
$x + 0;        // int(11)

$x = "0x11";
(int) $x;      // int(0)
intval($x);    // int(0)
$x + 0;        // int(17) !

$x = "011";
(int) $x;      // int(11)
intval($x);    // int(11)
$x + 0;        // int(11) (not 9)

_{Tested using PHP 5.3.1}

This is how a snapshot looks like for a repository and in this case is not enabled, which means that the repository referred in here is stable and there's no need for updates.

<project>
    ...
    <repositories>
        <repository>
            <id>lds-main</id>
            <name>LDS Main Repo</name>
            <url>http://code.lds.org/nexus/content/groups/main-repo</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>
</project>

Another case would be for:

<snapshots>
        <enabled>true</enabled>
</snapshots>

which means that Maven will look for updates for this repository. You can also specify an interval for the updates with tag.

java.lang.StringBuilder. Use int constructor to create an initial size.

Yes, Use jspdf To create a pdf file.

You can then turn it into a data URI and inject a download link into the DOM

You will however need to write the HTML to pdf conversion yourself.

Just use printer friendly versions of your page and let the user choose how he wants to print the page.

Edit: Apparently it has minimal support

So the answer is write your own PDF writer or get a existing PDF writer to do it for you (on the server).
