You can relocate it by editing the DocumentRoot setting in XAMPP\apache\conf\httpd.conf.

It should currently be:

C:/xampp/htdocs

Change it to:

C:/projects/transitCalculator/trunk

There is no place on your phone that you can read the System.out.println();

Instead, if you want to see the result of something either look at your logcat/console window or make a Toast or a Snackbar (if you're on a newer device) appear on the device's screen with the message :) That's what i do when i have to check for example where it goes in a switch case code! Have fun coding! :)

I have another one. I named my css file: default.css. It wouldn't load. When I tried to view it in the browser it showed an empty page.

I changed the name to default_css.css and it started working.

The other answers will break if output of command contains spaces (which is rather frequent) or glob characters like *, ?, [...].

To get the output of a command in an array, with one line per element, there are essentially 3 ways:

1. With Bash=4 use mapfile—it's the most efficient:

   mapfile -t my_array < <( my_command )
   

2. Otherwise, a loop reading the output (slower, but safe):

   my_array=()
   while IFS= read -r line; do
       my_array+=( "$line" )
   done < <( my_command )
   

3. As suggested by Charles Duffy in the comments (thanks!), the following might perform better than the loop method in number 2:

   IFS=$'\n' read -r -d '' -a my_array < <( my_command && printf '\0' )
   

   Please make sure you use exactly this form, i.e., make sure you have the following:

   • IFS=$'\n' on the same line as the read statement: this will only set the environment variable IFS for the read statement only. So it won't affect the rest of your script at all. The purpose of this variable is to tell read to break the stream at the EOL character \n.
   • -r: this is important. It tells read to not interpret the backslashes as escape sequences.
   • -d '': please note the space between the -d option and its argument ''. If you don't leave a space here, the '' will never be seen, as it will disappear in the quote removal step when Bash parses the statement. This tells read to stop reading at the nil byte. Some people write it as -d $'\0', but it is not really necessary. -d '' is better.
   • -a my_array tells read to populate the array my_array while reading the stream.
   • You must use the printf '\0' statement after my_command, so that read returns 0; it's actually not a big deal if you don't (you'll just get an return code 1, which is okay if you don't use set -e – which you shouldn't anyway), but just bear that in mind. It's cleaner and more semantically correct. Note that this is different from printf '', which doesn't output anything. printf '\0' prints a null byte, needed by read to happily stop reading there (remember the -d '' option?).

If you can, i.e., if you're sure your code will run on Bash=4, use the first method. And you can see it's shorter too.

If you want to use read, the loop (method 2) might have an advantage over method 3 if you want to do some processing as the lines are read: you have direct access to it (via the $line variable in the example I gave), and you also have access to the lines already read (via the array ${my_array[@]} in the example I gave).

Note that mapfile provides a way to have a callback eval'd on each line read, and in fact you can even tell it to only call this callback every N lines read; have a look at help mapfile and the options -C and -c therein. (My opinion about this is that it's a little bit clunky, but can be used sometimes if you only have simple things to do — I don't really understand why this was even implemented in the first place!).

Now I'm going to tell you why the following method:

my_array=( $( my_command) )

is broken when there are spaces:

$ # I'm using this command to test:
$ echo "one two"; echo "three four"
one two
three four
$ # Now I'm going to use the broken method:
$ my_array=( $( echo "one two"; echo "three four" ) )
$ declare -p my_array
declare -a my_array='([0]="one" [1]="two" [2]="three" [3]="four")'
$ # As you can see, the fields are not the lines
$
$ # Now look at the correct method:
$ mapfile -t my_array < <(echo "one two"; echo "three four")
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # Good!

Then some people will then recommend using IFS=$'\n' to fix it:

$ IFS=$'\n'
$ my_array=( $(echo "one two"; echo "three four") )
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # It works!

But now let's use another command, with globs:

$ echo "* one two"; echo "[three four]"
* one two
[three four]
$ IFS=$'\n'
$ my_array=( $(echo "* one two"; echo "[three four]") )
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="t")'
$ # What?

That's because I have a file called t in the current directory… and this filename is matched by the glob [three four]… at this point some people would recommend using set -f to disable globbing: but look at it: you have to change IFS and use set -f to be able to fix a broken technique (and you're not even fixing it really)! when doing that we're really fighting against the shell, not working with the shell.

$ mapfile -t my_array < <( echo "* one two"; echo "[three four]")
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="[three four]")'

here we're working with the shell!

conio.h is a C header file used in old MS-DOS compilers to create text user interfaces. Compilers that targeted non-DOS operating systems, such as Linux, Win32 and OS/2, provided different implementations of these functions.

The #include <curses.h> will give you almost all the functionalities that was provided in conio.h

nucurses need to be installed at the first place

In deb based Distros use

sudo apt-get install libncurses5-dev libncursesw5-dev

And in rpm based distros use

sudo yum install ncurses-devel ncurses

For getch() class of functions, you can try this

In Swift both 3&4

 func removeImageLocalPath(localPathName:String) {
            let filemanager = FileManager.default
            let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory,.userDomainMask,true)[0] as NSString
            let destinationPath = documentsPath.appendingPathComponent(localPathName)
 do {
        try filemanager.removeItem(atPath: destinationPath)
        print("Local path removed successfully")
    } catch let error as NSError {
        print("------Error",error.debugDescription)
    }
    }

or This method can delete all local file

func deletingLocalCacheAttachments(){
        let fileManager = FileManager.default
        let documentsURL = fileManager.urls(for: .documentDirectory, in: .userDomainMask)[0]
        do {
            let fileURLs = try fileManager.contentsOfDirectory(at: documentsURL, includingPropertiesForKeys: nil)
            if fileURLs.count > 0{
                for fileURL in fileURLs {
                    try fileManager.removeItem(at: fileURL)
                }
            }
        } catch {
            print("Error while enumerating files \(documentsURL.path): \(error.localizedDescription)")
        }
    }

#include<stdio.h>
int main()
{
    int arr[]={10,20,30,40,50,60};
    int *p;
    int count=0;

    for(p=arr;p<&arr+1;p++)
        count++;

    printf("The no of elements in array=%d",count);

    return 0;
}

OUTPUT=6

EXPLANATION

p is a pointer to a 1-D array, and in the loop for(p=arr,p<&arr+1;p++) I made p point to the base address. Suppose its base address is 1000; if we increment p then it points to 1002 and so on. Now coming to the concept of &arr - It basically represents the whole array, and if we add 1 to the whole array i.e. &arr+1, it gives the address 1012 i.e. the address of next 1-D array (in our case the size of int is 2), so the condition becomes 1000<1012.

So, basically the condition becomes

for(p=1000;p<1012;p++)

And now let's check the condition and count the value

• 1st time p=1000 and p<1012 condition is true: enter in the loop, increment the value of count to 1.
• 2nd time p=1002 and p<1012 condition is true: enter in the loop, increment the value of count to 2.
• ...
• 6th time p=1010 and p<1012 condition is true: enter in the loop, increment the value of count to 6.
• Last time p=1012 and p<1012 condition is false: print the value of count=6 in printf statement.

Unfortunately none of the solutions here worked for me (I get unresolved dependencies). What finally worked and is the easiest way IMHO is: Highlight the project name from Android Studio then File -> New Module -> Import JAR or AAR Package. Credit goes to the solution in this post

You can use pydoc.

Open your terminal and type python -m pydoc list.append

The advantage of pydoc over help() is that you do not have to import a module to look at its help text. For instance python -m pydoc random.randint.

Also you can start an HTTP server to interactively browse documentation by typing python -m pydoc -b (python 3)

For more information python -m pydoc

You can make full use of the && and || operators like this:

ps aux | grep some_proces[s] > /tmp/test.txt && echo 1 || echo 0

For excluding grep itself, you could also do something like:

ps aux | grep some_proces | grep -vw grep > /tmp/test.txt && echo 1 || echo 0

I recently had a similar problem and ended up fixing it using a mixture of different solutions.

The first and most simple one was to use two tables, one for the headers and one for the body. This works but the headers and the body columns are not aligned. And, since I wanted to use the auto-size that comes with twitter bootstrap tables I ended up creating a Javascript function that changes the headers when: the body is rendered; the windows is resized; the data in the column changes, etc.

Here is some of the code I used:

        <table class="table table-striped table-hover" style="margin-bottom: 0px;">
        <thead>
            <tr>
                <th data-sort="id">Header 1</i></th>
                <th data-sort="guide">Header 2</th>
                <th data-sort="origin">Header 3</th>
                <th data-sort="supplier">Header 4</th>
            </tr>
        </thead>
    </table>
    <div class="bodycontainer scrollable">
        <table class="table table-hover table-striped table-scrollable">
            <tbody id="rows"></tbody>
        </table>
    </div>

The headers and the body are divided in two separate tables. One of them is inside a DIV with the necessary style to generate the vertical scrollbars. Here is the CSS I used:

.bodycontainer {
  //height: 200px
  width: 100%;
  margin: 0;
}

.table-scrollable {
  margin: 0px;
  padding: 0px;
}

I commented the height here because I a wanted the table to reach the bottom of the page, whatever the page height might be.

The data-sort attributes I used in the headers are also used in every td. This way I could get the width and the padding of every td and the width of the row. Using the data-sort attributes I set using CSS the padding and width of each header accordingly and of the header row which is always bigger since it doesn´t have a scrollbar. Here is the function using coffeescript:

fixHeaders: =>
  for header, i in @headers
    tdpadding = parseInt(@$("td[data-sort=#{header}]").css('padding'))
    tdwidth = parseInt(@$("td[data-sort=#{header}]").css('width'))
    @$("th[data-sort=#{header}]").css('padding', tdpadding)
    @$("th[data-sort=#{header}]").css('width', tdwidth)
    if (i+1) == @headers.length
      trwidth = @$("td[data-sort=#{header}]").parent().css('width')
      @$("th[data-sort=#{header}]").parent().parent().parent().css('width', trwidth)
      @$('.bodycontainer').css('height', window.innerHeight - ($('html').outerHeight() -@$('.bodycontainer').outerHeight() ) ) unless @collection.length == 0

Here I assume that you have an array of the headers called @headers.

It is not pretty but it works. Hope it helps someone.

Other answers to this question do not return what the OP needs, they will return a string like:

test1 test2 test3 test1 test3 test4

(notice that test1 and test3 are duplicated) while the OP wants to return this string:

test1 test2 test3 test4

the problem here is that the string "test1 test3" is duplicated and is inserted only once, but all of the others are distinct to each other ("test1 test2 test3" is distinct than "test1 test3", even if some tests contained in the whole string are duplicated).

What we need to do here is to split each string into different rows, and we first need to create a numbers table:

CREATE TABLE numbers (n INT);
INSERT INTO numbers VALUES
(1),(2),(3),(4),(5),(6),(7),(8),(9),(10);

then we can run this query:

SELECT
  SUBSTRING_INDEX(
    SUBSTRING_INDEX(tableName.categories, ' ', numbers.n),
    ' ',
    -1) category
FROM
  numbers INNER JOIN tableName
  ON
    LENGTH(tableName.categories)>=
    LENGTH(REPLACE(tableName.categories, ' ', ''))+numbers.n-1;

and we get a result like this:

test1
test4
test1
test1
test2
test3
test3
test3

and then we can apply GROUP_CONCAT aggregate function, using DISTINCT clause:

SELECT
  GROUP_CONCAT(DISTINCT category ORDER BY category SEPARATOR ' ')
FROM (
  SELECT
    SUBSTRING_INDEX(SUBSTRING_INDEX(tableName.categories, ' ', numbers.n), ' ', -1) category
  FROM
    numbers INNER JOIN tableName
    ON LENGTH(tableName.categories)>=LENGTH(REPLACE(tableName.categories, ' ', ''))+numbers.n-1
  ) s;

Please see fiddle here.

action="" will resolve to the page's address. action="#" will resolve to the page's address + #, which will mean an empty fragment identifier.

Doing the latter might prevent a navigation (new load) to the same page and instead try to jump to the element with the id in the fragment identifier. But, since it's empty, it won't jump anywhere.

Usually, authors just put # in href-like attributes when they're not going to use the attribute where they're using scripting instead. In these cases, they could just use action="" (or omit it if validation allows).

int main()
{
  int size;

  std::cin >> size;

  int *array = new int[size];

  delete [] array;

  return 0;
}

Don't forget to delete every array you allocate with new.

Sometimes, you really don't care about the collection itself. For instance, creating a simple model fit line to compare an "approximation" with the raw data:

fib_raw = [1, 1, 2, 3, 5, 8, 13, 21] # Fibonacci numbers

phi = (1 + sqrt(5)) / 2
phi2 = (1 - sqrt(5)) / 2

def fib_approx(n): return (phi**n - phi2**n) / sqrt(5)

x = range(len(data))
y = [fib_approx(n) for n in x]

# Now plot to compare fib_raw and y
# Compare error, etc

In this case, the values of the Fibonacci sequence itself were irrelevant. All we needed here was the size of the input sequence we were comparing with.

your button xml:

 <Button
    android:id="@+id/btn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="jump to activity b"
    />

Mainactivity.java:

 Button btn=findViewVyId(R.id.btn);
btn.setOnClickListener(btnclick);
btnclick.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
               Intent intent=new Intent();
                intent.setClass(Mainactivity.this,b.class);
                startActivity(intent);
    }
});

**It is Simple, just follow 2 steps. Step #1. Fire query "Delete from tableName", It will delete all records from table.

Step #2. There is table named "sqlite_sequence" in Sqlite Database, just browse it and you can set sequence table wise to "0" so it will start from auto id "1".** See the screenshot attached.

You can try this:-

Process p = Runtime.getRuntime().exec(command);

Make sure you have closed your MSAccess file before running the java program.

Why not wrap the content you don't want shown in an element with a class and set that class to display:none in a stylesheet meant only for the iphone and other handheld devices?

setInterval as suggested by SLaks was exactly what I needed to make my timer. (Thanks mate!)

Using setInterval and this great blog post I ended up creating the following function to display a timer inside my "box_header" div. I hope this helps anyone else with similar requirements!

 function get_elapsed_time_string(total_seconds) {
  function pretty_time_string(num) {
    return ( num < 10 ? "0" : "" ) + num;
  }

  var hours = Math.floor(total_seconds / 3600);
  total_seconds = total_seconds % 3600;

  var minutes = Math.floor(total_seconds / 60);
  total_seconds = total_seconds % 60;

  var seconds = Math.floor(total_seconds);

  // Pad the minutes and seconds with leading zeros, if required
  hours = pretty_time_string(hours);
  minutes = pretty_time_string(minutes);
  seconds = pretty_time_string(seconds);

  // Compose the string for display
  var currentTimeString = hours + ":" + minutes + ":" + seconds;

  return currentTimeString;
}

var elapsed_seconds = 0;
setInterval(function() {
  elapsed_seconds = elapsed_seconds + 1;
  $('#box_header').text(get_elapsed_time_string(elapsed_seconds));
}, 1000);

You need to call newTest to make the functions declared inside that method “visible” (see Functions within functions). But that are then just normal functions and no methods.

Subtle, but this error got me because I forgot to declare a smallint column as unsigned to match the referenced, existing table which was "smallint unsigned." Having one unsigned and one not unsigned caused MySQL to prevent the foreign key from being created on the new table.

id smallint(3) not null

does not match, for the sake of foreign keys,

id smallint(3) unsigned not null

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

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

var str = 'Dude, he totally said that "You Rock!"';
var var1 = str.replace(/\"/g,"\\\"");
alert(var1);

Suggest calling 'Now' only once in the function to guard against the minute, or even the day, changing during the execution of the function.

Thus:

Function timeStamp()
    Dim t 
    t = Now
    timeStamp = Year(t) & "-" & _
    Right("0" & Month(t),2)  & "-" & _
    Right("0" & Day(t),2)  & "_" & _  
    Right("0" & Hour(t),2) & _
    Right("0" & Minute(t),2) '    '& _    Right("0" & Second(t),2) 
End Function

Inline SVG can be used in IE 10 and 11 and Edge 12.

I've created a project called gray which includes a polyfill for these browsers. The polyfill switches out <img> tags with inline SVG: https://github.com/karlhorky/gray

To implement, the short version is to download the jQuery plugin at the GitHub link above and add after jQuery at the end of your body:

<script src="/js/jquery.gray.min.js"></script>

Then every image with the class grayscale will appear as gray.

<img src="/img/color.jpg" class="grayscale">

You can see a demo too if you like.

Is Java smart enough to skip checking bool2 and bool2 if bool1 was evaluated to false?

Its not a matter of being smart, its a requirement specified in the language. Otherwise you couldn't write expressions like.

if(s != null && s.length() > 0)

or

if(s == null || s.length() == 0)

BTW if you use & and | it will always evaluate both sides of the expression.

There are two ways you can use spinner:

static way

android:spinnerMode="dialog"

and then set:

android:prompt="@string/hint_resource"

dynamic way

spinner.setPrompt("Gender");

Note: It will work like a Hint but not actually it is.

May it help!

Dave Markle is correct. From W3School's website:

Always specify the type attribute for the button. The default type for Internet Explorer is "button", while in other browsers (and in the W3C specification) it is "submit".

In other words, the browser you're using is following W3C's specification.

I had a similar problem but with the specific requirement to have the CORS header set from decorators in our endpoints, like this:

@CrossOrigin(origins = "*", allowCredentials = "true")
@PostMapping(value = "/login")

Or

@CrossOrigin(origins = "*")
@GetMapping(value = "/verificationState")

So simply intercepting the request, setting the CORS header manually and sending 200 back was not an option, because allowCredentials was needed to be true in some cases and wildcards are not allowed then. Sure, a CORS registry would have helped, but since our clients are angular in capacitor on android and iOS, there is no specific domain to register. So the clean way to do - in my opinion - is to pipe preflights directly to the endpoints to let them handle it. I solved it with this:

@Component
public class PreflightFilter extends OncePerRequestFilter {

    private static final Logger logger = LoggerFactory.getLogger(PreflightFilter.class);

    @Override
    protected void doFilterInternal(HttpServletRequest request,
                                    HttpServletResponse response, FilterChain chain)
            throws ServletException, IOException {

        if (CorsUtils.isPreFlightRequest(request)) {
            logger.info("Preflight request accepted");
            SecurityContextHolder.getContext().setAuthentication(createPreflightToken(request));
        }
        chain.doFilter(request, response);
    }

    private UsernamePasswordAuthenticationToken createPreflightToken(HttpServletRequest request) {
        UserDetails userDetails = new User("Preflight", "",
                true, true, true, true,
                Stream.of(new SimpleGrantedAuthority("AppUser")).collect(Collectors.toSet()));
        UsernamePasswordAuthenticationToken preflightToken =
                new UsernamePasswordAuthenticationToken(
                        userDetails, null, userDetails.getAuthorities());
        preflightToken
                .setDetails(new WebAuthenticationDetailsSource().buildDetails(request));
        return preflightToken;
    }
}

Keep in mind that the endpoint decorators don't work like wildcards here as one would expect!

You can use operator.setitem.

from operator import setitem
a = [5, 4, 3, 2, 1, 0]
ell = [0, 1, 3, 5]
m = [0, 0, 0, 0]
for b, c in zip(ell, m):
    setitem(a, b, c)
>>> a
[0, 0, 3, 0, 1, 0]

Is it any more readable or efficient than your solution? I am not sure!

Say that you like to maintain Width: 100px and the Height: 50px (i.e., 2:1) Just do this math:

.pb-2to1 {
  padding-bottom: calc(50 / 100 * 100%); // i.e., 2:1
}

Expansion for multi-dimension array total length,

Generally for your case, since the shape of the 2D array is "squared".

int length = nir.length * nir[0].length;

However, for 2D array, each row may not have the exact same number of elements. Therefore we need to traverse through each row, add number of elements up.

int length = 0;
for ( int lvl = 0; lvl < _levels.length; lvl++ )
{
    length += _levels[ lvl ].length;
}

If N-D array, which means we need N-1 for loop to get each row's size.

Check your my.cnf file in your MySQL program directory, look for

[mysqld]
datadir=

The datadir is the location where your MySQL database is stored.

Use getattr if you have an attribute in string form:

>>> class User(object):
       name = 'John'

>>> u = User()
>>> param = 'name'
>>> getattr(u, param)
'John'

Otherwise use the dot .:

>>> class User(object):
       name = 'John'

>>> u = User()
>>> u.name
'John'

Use the mod rewrite with R=301 - where you use a incremental version number:

To achieve > css/ver/file.css => css/file.css?v=ver

RewriteRule ^css/([0-9]+)/file.css$ css/file.css?v=$1 [R=301,L,QSA]

so example, css/10/file.css => css/file.css?v=10

Same can be applied to js/ files. Increment ver to force update, 301 forces re-cache

I have tested this across Chrome, Firefox, Opera etc

PS: the ?v=ver is just for readability, this does not cause the refresh

The actual answer to this (reduce) problem is: Just use a loop!

initial_value = 0
for x in the_list:
    initial_value += x #or any function.

This will be faster than a reduce and things like PyPy can optimize loops like that.

BTW, the sum case should be solved with the sum function

Only using css techniques this does not seem possible to me. But you could use jqueryui draggable:

$('#drag_me').draggable();

As of Visual Studio 2012, Microsoft no longer provides the built-in deployment package. If you wish to use this package, you will need to use VS2010.

In 2013 you have several options:

• InstallShield
• WiX
• Roll your own

In my projects I create my own installers from scratch, which, since I do not use Windows Installer, have the advantage of being super fast, even on old machines.

There is an alternative command where you can get the raw value of a cell where formula is put on. It's returns type is String. Use:

cell.getRawValue();

Use substr():

$result = substr($myStr, 0, 5);

This will do it to every line in the file:

:%s/$/,/

If you want to do a subset of lines instead of the whole file, you can specify them in place of the %.

One way is to do a visual select and then type the :. It will fill in :'<,'> for you, then you type the rest of it (Notice you only need to add s/$/,/)

:'<,'>s/$/,/

char buffer [50];

unsigned long a = 5;

int n=sprintf (buffer, "%lu", a);

In Stored procedure, you return the values using OUT parameter ONLY. As you have defined two variables in your example:

   outstaticip OUT VARCHAR2, outcount OUT NUMBER

Just assign the return values to the out parameters i.e. outstaticip and outcount and access them back from calling location. What I mean here is: when you call the stored procedure, you will be passing those two variables as well. After the stored procedure call, the variables will be populated with return values.

If you want to have RETURN value as return from the PL/SQL call, then use FUNCTION. Please note that in case, you would be able to return only one variable as return variable.

The ubuntu package name is qt5-default, not qt.

You add your ActionListener twice to button. So correct your code for button2 to

  JButton button2 = new JButton("hello agin2");
  panel.add(button2);
  button2.addActionListener (new Action2());//note the button2 here instead of button

Furthermore, perform your Swing operations on the correct thread by using EventQueue.invokeLater

You can do this with plain js by using

1. location.host , same as document.location.hostname
2. document.domain Not recommended

This should answer that question, and then some.

The second line, if (obj.GetType() == typeof(ClassA)) {}, is faster, for those that don't want to read the article.

(Be aware that they don't do the same thing)

If you use the relative version on http://www.foo.com/abc your browser will look at http://www.foo.com/abc/kitten.png for the image and would get 404 - Not found.

Your question is somewhat difficult because even the function:

static FooBar MakeFooBar(int foo, float bar);

may be called as:

FooBar fb = MakeFooBar(3.4, 5);

because of the promotion and conversions rules for built-in numeric types. (C has never been really strongly typed)

In C++, what you want is achievable, though with the help of templates and static assertions:

template <typename Integer, typename Real>
FooBar MakeFooBar(Integer foo, Real bar) {
  static_assert(std::is_same<Integer, int>::value, "foo should be of type int");
  static_assert(std::is_same<Real, float>::value, "bar should be of type float");
  return { foo, bar };
}

In C, you may name the parameters, but you'll never get further.

On the other hand, if all you want is named parameters, then you write a lot of cumbersome code:

struct FooBarMaker {
  FooBarMaker(int f): _f(f) {}
  FooBar Bar(float b) const { return FooBar(_f, b); }
  int _f;
};

static FooBarMaker Foo(int f) { return FooBarMaker(f); }

// Usage
FooBar fb = Foo(5).Bar(3.4);

And you can pepper in type promotion protection if you like.

use this command php artisan migrate --path=/database/migrations/my_migration.php it worked for me..

Try listening for events in the parent document and passing the event to a handler in the iframe document.

You can use a Global Mixin to affect every Vue instance. You can add data to this mixin, making a value/values available to all vue components.

To make that value Read Only, you can use the method described in this Stack Overflow answer.

Here is an example:

// This is a global mixin, it is applied to every vue instance. 
// Mixins must be instantiated *before* your call to new Vue(...)
Vue.mixin({
  data: function() {
    return {
      get globalReadOnlyProperty() {
        return "Can't change me!";
      }
    }
  }
})

Vue.component('child', {
  template: "<div>In Child: {{globalReadOnlyProperty}}</div>"
});

new Vue({
  el: '#app',
  created: function() {
    this.globalReadOnlyProperty = "This won't change it";
  }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.1.3/vue.js"></script>
<div id="app">
  In Root: {{globalReadOnlyProperty}}
  <child></child>
</div>

It's a pity to use .NET and not use collections and lambda to save your time and code lines This is an example of how this works: Transform yourDataTable to Enumerable, filter it if you want , according a "FILTER_ROWS_FIELD" column, and if you want, group your data by a "A_GROUP_BY_FIELD". Then get the count, the sum, or whatever you wish. If you want a count and a sum without grouby don't group the data

var groupedData = from b in yourDataTable.AsEnumerable().Where(r=>r.Field<int>("FILTER_ROWS_FIELD").Equals(9999))
                          group b by b.Field<string>("A_GROUP_BY_FIELD") into g
                          select new
                          {
                              tag = g.Key,
                              count = g.Count(),
                              sum = g.Sum(c => c.Field<double>("rvMoney"))
                          };

Give each input a name attribute. Only the clicked input's name attribute will be sent to the server.

<input type="submit" name="publish" value="Publish">
<input type="submit" name="save" value="Save">

And then

<?php
    if (isset($_POST['publish'])) {
        # Publish-button was clicked
    }
    elseif (isset($_POST['save'])) {
        # Save-button was clicked
    }
?>

Edit: Changed value attributes to alt. Not sure this is the best approach for image buttons though, any particular reason you don't want to use input[type=image]?

Edit: Since this keeps getting upvotes I went ahead and changed the weird alt/value code to real submit inputs. I believe the original question asked for some sort of image buttons but there are so much better ways to achieve that nowadays instead of using input[type=image].

Another option with pure CSS would be something like this:

nav {
    margin: 0px auto;
    width: 100%;
    height: 50px;
    background-color: white;
    float: left;
    padding: 10px;
    border: 2px solid red;
    position: relative;
    z-index: 10;
}

nav:after {
    background-color: grey;
    content: '';
    display: block;
    position: absolute;
    top: 10px;
    left: 10px;
    right: 10px;
    bottom: 10px;
    z-index: -1;
}

Demo here

TextView forgot_pswrd = (TextView) findViewById(R.id.ForgotPasswordText);
forgot_pswrd.setOnTouchListener(this);     
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
llp.setMargins(50, 0, 0, 0); // llp.setMargins(left, top, right, bottom);
forgot_pswrd.setLayoutParams(llp);

I did this and it worked perfectly. Maybe as you are giving the value in -ve, that's why your code is not working. You just put this code where you are creating the reference of the view.

It uses commas as separators. So you can either set sep="," or just use read.csv:

x <- read.csv(file="http://www.irs.gov/file_source/pub/irs-soi/countyinflow1011.csv")
dim(x)
## [1] 113593      9

The error is caused by spaces in some of the values, and unmatched quotes. There are no spaces in the header, so read.table thinks that there is one column. Then it thinks it sees multiple columns in some of the rows. For example, the first two lines (header and first row):

State_Code_Dest,County_Code_Dest,State_Code_Origin,County_Code_Origin,State_Abbrv,County_Name,Return_Num,Exmpt_Num,Aggr_AGI
00,000,96,000,US,Total Mig - US & For,6973489,12948316,303495582

And unmatched quotes, for example on line 1336 (row 1335) which will confuse read.table with the default quote argument (but not read.csv):

01,089,24,033,MD,Prince George's County,13,30,1040

Just add http://download.eclipse.org/egit/updates to your Eclipse update manager.

You can create your own AuthorizationHandler that will find custom attributes on your Controllers and Actions, and pass them to the HandleRequirementAsync method.

public abstract class AttributeAuthorizationHandler<TRequirement, TAttribute> : AuthorizationHandler<TRequirement> where TRequirement : IAuthorizationRequirement where TAttribute : Attribute
{
    protected override Task HandleRequirementAsync(AuthorizationHandlerContext context, TRequirement requirement)
    {
        var attributes = new List<TAttribute>();

        var action = (context.Resource as AuthorizationFilterContext)?.ActionDescriptor as ControllerActionDescriptor;
        if (action != null)
        {
            attributes.AddRange(GetAttributes(action.ControllerTypeInfo.UnderlyingSystemType));
            attributes.AddRange(GetAttributes(action.MethodInfo));
        }

        return HandleRequirementAsync(context, requirement, attributes);
    }

    protected abstract Task HandleRequirementAsync(AuthorizationHandlerContext context, TRequirement requirement, IEnumerable<TAttribute> attributes);

    private static IEnumerable<TAttribute> GetAttributes(MemberInfo memberInfo)
    {
        return memberInfo.GetCustomAttributes(typeof(TAttribute), false).Cast<TAttribute>();
    }
}

Then you can use it for any custom attributes you need on your controllers or actions. For example to add permission requirements. Just create your custom attribute.

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = true)]
public class PermissionAttribute : AuthorizeAttribute
{
    public string Name { get; }

    public PermissionAttribute(string name) : base("Permission")
    {
        Name = name;
    }
}

Then create a Requirement to add to your Policy

public class PermissionAuthorizationRequirement : IAuthorizationRequirement
{
    //Add any custom requirement properties if you have them
}

Then create the AuthorizationHandler for your custom attribute, inheriting the AttributeAuthorizationHandler that we created earlier. It will be passed an IEnumerable for all your custom attributes in the HandleRequirementsAsync method, accumulated from your Controller and Action.

public class PermissionAuthorizationHandler : AttributeAuthorizationHandler<PermissionAuthorizationRequirement, PermissionAttribute>
{
    protected override async Task HandleRequirementAsync(AuthorizationHandlerContext context, PermissionAuthorizationRequirement requirement, IEnumerable<PermissionAttribute> attributes)
    {
        foreach (var permissionAttribute in attributes)
        {
            if (!await AuthorizeAsync(context.User, permissionAttribute.Name))
            {
                return;
            }
        }

        context.Succeed(requirement);
    }

    private Task<bool> AuthorizeAsync(ClaimsPrincipal user, string permission)
    {
        //Implement your custom user permission logic here
    }
}

And finally, in your Startup.cs ConfigureServices method, add your custom AuthorizationHandler to the services, and add your Policy.

        services.AddSingleton<IAuthorizationHandler, PermissionAuthorizationHandler>();

        services.AddAuthorization(options =>
        {
            options.AddPolicy("Permission", policyBuilder =>
            {
                policyBuilder.Requirements.Add(new PermissionAuthorizationRequirement());
            });
        });

Now you can simply decorate your Controllers and Actions with your custom attribute.

[Permission("AccessCustomers")]
public class CustomersController
{
    [Permission("AddCustomer")]
    IActionResult AddCustomer([FromBody] Customer customer)
    {
        //Add customer
    }
}

Java does have unsigned types, or at least one: char is an unsigned short. So whatever excuse Gosling throws up it's really just his ignorance why there are no other unsigned types.

Also Short types: shorts are used all the time for multimedia. The reason is you can fit 2 samples in a single 32-bit unsigned long and vectorize many operations. Same thing with 8-bit data and unsigned byte. You can fit 4 or 8 samples in a register for vectorizing.

The syntax to store the command output into a variable is var=$(command).

So you can directly do:

result=$(ls -l | grep -c "rahul.*patle")

And the variable $result will contain the number of matches.

I'll post this comment as answer, as I'm confident enough that what I asked is not possible.

I) Couple of similar questions trying to do the same, without success:

• Pivot Calculated formula: SUM(Field1)/AVG(Field2)
• Excel Pivot Table Calculated Field

II) This article: Excel Pivot Table Calculated Field for example lists many restrictions of Calculated Field:

• For calculated fields, the individual amounts in the other fields are summed, and then the calculation is performed on the total amount.
• Calculated field formulas cannot refer to the pivot table totals or subtotals
• Calculated field formulas cannot refer to worksheet cells by address or by name.
• Sum is the only function available for a calculated field.
• Calculated fields are not available in an OLAP-based pivot table.

III) There is tiny limited possibility to use AVERAGE() and similar function for a range of cells, but that applies only if Pivot table doesn't have grouped cells, which allows listing the cells as items in new group (right to "Fileds" listbox in above screenshot) and then user can calculate AVERAGE(), referencing explicitly every item (cell), from Items listbox, as argument. Maybe it's better explained here: Calculate values in a PivotTable report
For my Pivot table it wasn't applicable because my range wasn't small enough, this option to be sane choice.

I've successful installed Google Maps v2 on an emulator using this guide.
You should do the following steps:

• Create a new emulator Nexus S, Android 2.3.3. Don't use Google API.
• Install com.android.vending.apk (Google Play Store, v.3.10.9)
• Install com.google.android.gms.apk (Google Play Service, v.2.0.12)

Using the Java client of Kafka 2.11-1.0.0, you can do the following thing :

    KafkaConsumer<String, String> consumer = new KafkaConsumer<>(props);
    consumer.subscribe(Collections.singletonList("test"));
    while(true) {
        ConsumerRecords<String, String> records = consumer.poll(100);
        for (ConsumerRecord<String, String> record : records) {
            System.out.printf("offset = %d, key = %s, value = %s%n", record.offset(), record.key(), record.value());

            // after each message, query the number of messages of the topic
            Set<TopicPartition> partitions = consumer.assignment();
            Map<TopicPartition, Long> offsets = consumer.endOffsets(partitions);
            for(TopicPartition partition : offsets.keySet()) {
                System.out.printf("partition %s is at %d\n", partition.topic(), offsets.get(partition));
            }
        }
    }

Output is something like this :

offset = 10, key = null, value = un
partition test is at 13
offset = 11, key = null, value = deux
partition test is at 13
offset = 12, key = null, value = trois
partition test is at 13

You may also use the stringr package

library(dplyr)
library(stringr)
My.Data %>% filter(str_detect(x, '^G45'))

You may not use '^' (starts with) in this case, to obtain the results you need

It's similar to above but you can try like

public Integer count(String tableName) throws CrateException {
        String query = String.format("Select count(*) as size from %s", tableName);
        try (Statement s = connection.createStatement()) {
            try (ResultSet resultSet = queryExecutor.executeQuery(s, query)) {
                Preconditions.checkArgument(resultSet.next(), "Result set is empty");
                return resultSet.getInt("size");
            }
        } catch (SQLException e) {
            throw new CrateException(e);
        }
    }
}

If your cascading deletes nuke a product because it was a member of a category that was killed, then you've set up your foreign keys improperly. Given your example tables, you should have the following table setup:

CREATE TABLE categories (
    id int unsigned not null primary key,
    name VARCHAR(255) default null
)Engine=InnoDB;

CREATE TABLE products (
    id int unsigned not null primary key,
    name VARCHAR(255) default null
)Engine=InnoDB;

CREATE TABLE categories_products (
    category_id int unsigned not null,
    product_id int unsigned not null,
    PRIMARY KEY (category_id, product_id),
    KEY pkey (product_id),
    FOREIGN KEY (category_id) REFERENCES categories (id)
       ON DELETE CASCADE
       ON UPDATE CASCADE,
    FOREIGN KEY (product_id) REFERENCES products (id)
       ON DELETE CASCADE
       ON UPDATE CASCADE
)Engine=InnoDB;

This way, you can delete a product OR a category, and only the associated records in categories_products will die alongside. The cascade won't travel farther up the tree and delete the parent product/category table.

e.g.

products: boots, mittens, hats, coats
categories: red, green, blue, white, black

prod/cats: red boots, green mittens, red coats, black hats

If you delete the 'red' category, then only the 'red' entry in the categories table dies, as well as the two entries prod/cats: 'red boots' and 'red coats'.

The delete will not cascade any farther and will not take out the 'boots' and 'coats' categories.

comment followup:

you're still misunderstanding how cascaded deletes work. They only affect the tables in which the "on delete cascade" is defined. In this case, the cascade is set in the "categories_products" table. If you delete the 'red' category, the only records that will cascade delete in categories_products are those where category_id = red. It won't touch any records where 'category_id = blue', and it would not travel onwards to the "products" table, because there's no foreign key defined in that table.

Here's a more concrete example:

categories:     products:
+----+------+   +----+---------+
| id | name |   | id | name    |
+----+------+   +----+---------+
| 1  | red  |   | 1  | mittens |
| 2  | blue |   | 2  | boots   |
+---++------+   +----+---------+

products_categories:
+------------+-------------+
| product_id | category_id |
+------------+-------------+
| 1          | 1           | // red mittens
| 1          | 2           | // blue mittens
| 2          | 1           | // red boots
| 2          | 2           | // blue boots
+------------+-------------+

Let's say you delete category #2 (blue):

DELETE FROM categories WHERE (id = 2);

the DBMS will look at all the tables which have a foreign key pointing at the 'categories' table, and delete the records where the matching id is 2. Since we only defined the foreign key relationship in products_categories, you end up with this table once the delete completes:

+------------+-------------+
| product_id | category_id |
+------------+-------------+
| 1          | 1           | // red mittens
| 2          | 1           | // red boots
+------------+-------------+

There's no foreign key defined in the products table, so the cascade will not work there, so you've still got boots and mittens listed. There's just no 'blue boots' and no 'blue mittens' anymore.

To get rid of the white color you have to set the background-color to transparent:

button {
  font-size: 18px;
  border: 2px solid #AD235E;
  border-radius: 100px;
  width: 150px;
  height: 150px;
  background-color: transparent; /* like this */
}

display: none or visibility: hidden.

Another way (depending on your actual needs): If you want to pop the first n characters and save both the popped characters and the modified string:

s = 'lipsum'
n = 3
a, s = s[:n], s[n:]
print(a)
# lip
print(s)
# sum

None of previous answers worked for me.

I noticed that my project was referencing another project using the System.Web.Mvc reference from the .NET Framework.

I just deleted that assembly and added the "Microsoft.AspNet.Mvc" NuGet package and that fixed my problem.

No need to include JQuery or any other third party library.

Specify your input date format in title tag.

HTML:

<script type="text/javascript" src="http://services.iperfect.net/js/IP_generalLib.js">

Have you tried using JsonSlurper?

Example usage:

def slurper = new JsonSlurper()
def result = slurper.parseText('{"person":{"name":"Guillaume","age":33,"pets":["dog","cat"]}}')

assert result.person.name == "Guillaume"
assert result.person.age == 33
assert result.person.pets.size() == 2
assert result.person.pets[0] == "dog"
assert result.person.pets[1] == "cat"

EncloseJS.

You get a fully functional binary without sources.

Native modules also supported. (must be placed in the same folder)

JavaScript code is transformed into native code at compile-time using V8 internal compiler. Hence, your sources are not required to execute the binary, and they are not packaged.

Perfectly optimized native code can be generated only at run-time based on the client's machine. Without that info EncloseJS can generate only "unoptimized" code. It runs about 2x slower than NodeJS.

Also, node.js runtime code is put inside the executable (along with your code) to support node API for your application at run-time.

Use cases:

• Make a commercial version of your application without sources.
• Make a demo/evaluation/trial version of your app without sources.
• Make some kind of self-extracting archive or installer.
• Make a closed source GUI application using node-thrust.
• No need to install node and npm to deploy the compiled application.
• No need to download hundreds of files via npm install to deploy your application. Deploy it as a single independent file.
• Put your assets inside the executable to make it even more portable. Test your app against new node version without installing it.

what about this

You can use the plugin ConyEdit to do this. With ConyEdit running in the background, follow these steps:

1. use the command line cc.spc /\t/ a to split the text into columns and store them in a two-dim array.
2. use the command cc.p to print, using the contents of the array.

Apparently jQuery now provides jQuery.parseXML http://api.jquery.com/jQuery.parseXML/ as of version 1.5

jQuery.parseXML( data ) Returns: XMLDocument

For debugging purposes I will often use YAML.

use strict;
use warnings;

use YAML;

my %variable = ('abc' => 123, 'def' => [4,5,6]);

print "# %variable\n", Dump \%variable;

Results in:

# %variable
---
abc: 123
def:
  - 4
  - 5
  - 6

Other times I will use Data::Dump. You don't need to set as many variables to get it to output it in a nice format than you do for Data::Dumper.

use Data::Dump = 'dump';

print dump(\%variable), "\n";

{ abc => 123, def => [4, 5, 6] }

More recently I have been using Data::Printer for debugging.

use Data::Printer;
p %variable;

{
    abc   123,
    def   [
        [0] 4,
        [1] 5,
        [2] 6
    ]
}

( Result can be much more colorful on a terminal )

Unlike the other examples I have shown here, this one is designed explicitly to be for display purposes only. Which shows up more easily if you dump out the structure of a tied variable or that of an object.

use strict;
use warnings;

use MTie::Hash;
use Data::Printer;

my $h = tie my %h, "Tie::StdHash";
@h{'a'..'d'}='A'..'D';
p %h;
print "\n";
p $h;

{
    a   "A",
    b   "B",
    c   "C",
    d   "D"
} (tied to Tie::StdHash)

Tie::StdHash  {
    public methods (9) : CLEAR, DELETE, EXISTS, FETCH, FIRSTKEY, NEXTKEY, SCALAR, STORE, TIEHASH
    private methods (0)
    internals: {
        a   "A",
        b   "B",
        c   "C",
        d   "D"
    }
}

In addition to all the regular confusion around SAP issues might also stem form the fact that SAP used to have their own DBMS ..

It used to be called Adabas (marketed originally by Nixdorf and then by Software AG) and was a quite popular DBMS for smaller SAP (the ERP solution) installations in Germany. At some point (AFAIK around 2000) SAP started to co-develop/support/take over Adabas and marketed it as SAP DB and later MaxDB under commercial and open-source licenses. There also was/is some agreement with MySQL.

But when people talk about SAP, they usually refer to the ERP solution as the other posters have noted.

In MVC 3 I had to add:

using System.ComponentModel.DataAnnotations;

among usings when adding properties:

[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]

Especially if you are adding these properties in .edmx file like me. I found that by default .edmx files don't have this using so adding only propeties is not enough.

 private void HighLightGridRows()

             dtgvAppSettings.Rows[i].DefaultCellStyle.BackColor = Color.Yellow;
         }
     }
 }

Just worked out for another solution as above example have bug( somewhere error ) for me. Variation from the selected answer.

html,body {
    height: 100%
}

#nonFooter {
    min-height: 100%;
    position:relative;
    /* Firefox */
    min-height: -moz-calc(100% - 30px);
    /* WebKit */
    min-height: -webkit-calc(100% - 30px);
    /* Opera */
    min-height: -o-calc(100% - 30px);
    /* Standard */
    min-height: calc(100% - 30px);
}

#footer {
    height:30px;
    margin: 0;
    clear: both;
    width:100%;
    position: relative;
}

for html layout

<body>
    <div id="nonFooter">header,middle,left,right,etc</div>
    <div id="footer"></div>
</body>

Well this way don't support old browser however its acceptable for old browser to scrolldown 30px to view the footer

You have one choice hide your back button and make it with your self. Then set its color.

I did that:

self.navigationItem.setHidesBackButton(true, animated: true)
let backbtn = UIBarButtonItem(title: "Back", style:UIBarButtonItemStyle.Plain, target: self, action: "backTapped:")
self.navigationItem.leftBarButtonItem = backbtn
self.navigationItem.leftBarButtonItem?.tintColor = UIColor.grayColor()

For those with a git gui bent, you can also use gitk.

Right click on the commit you want to return to and select "Reset master branch to here". Then choose hard from the next menu.

The only way to ensure code is executed is to place your setTimeout logic in a different process.

Use the child process module to spawn a new node.js program that does your logic and pass data to that process through some kind of a stream (maybe tcp).

This way even if some long blocking code is running in your main process your child process has already started itself and placed a setTimeout in a new process and a new thread and will thus run when you expect it to.

Further complication are at a hardware level where you have more threads running then processes and thus context switching will cause (very minor) delays from your expected timing. This should be neglible and if it matters you need to seriously consider what your trying to do, why you need such accuracy and what kind of real time alternative hardware is available to do the job instead.

In general using child processes and running multiple node applications as separate processes together with a load balancer or shared data storage (like redis) is important for scaling your code.

For those using a Windows OS, I was able to import a large mysqldump file into my local XAMPP installation using this command in cmd.exe:

C:\xampp\mysql\bin>mysql -u {DB_USER} -p {DB_NAME} < path/to/file/ab.sql

Also, I just wrote a more detailed answer to another question on MySQL imports, if this is what you're after.

If you need it to work on both Mac and Windows, you can use QueryTables:

With ActiveSheet.QueryTables.Add(Connection:="URL;http://carbon.brighterplanet.com/flights.txt", Destination:=Range("A2"))
    .PostText = "origin_airport=MSN&destination_airport=ORD"
    .RefreshStyle = xlOverwriteCells
    .SaveData = True
    .Refresh
End With

Notes:

• Regarding output... I don't know if it's possible to return the results to the same cell that called the VBA function. In the example above, the result is written into A2.
• Regarding input... If you want the results to refresh when you change certain cells, make sure those cells are the argument to your VBA function.
• This won't work on Excel for Mac 2008, which doesn't have VBA. Excel for Mac 2011 got VBA back.

For more details, you can see my full summary about "using web services from Excel."

One obvious and straightforward possibility is to use "if-else conditions". In that example

x <- c(1, 2, 4)
y <- c(1, 4, 5)
w <- ifelse(x <= 1, "good", ifelse((x >= 3) & (x <= 5), "bad", "fair"))
data.frame(x, y, w)

** For the additional question in the edit** Is that what you expect ?

> d1 <- c("e", "c", "a")
> d2 <- c("e", "a", "b")
> 
> w <- ifelse((d1 == "e") & (d2 == "e"), 1, 
+    ifelse((d1=="a") & (d2 == "b"), 2,
+    ifelse((d1 == "e"), 3, 99)))
>     
> data.frame(d1, d2, w)
  d1 d2  w
1  e  e  1
2  c  a 99
3  a  b  2

If you do not feel comfortable with the ifelse function, you can also work with the if and else statements for such applications.

Might be you forgotten to place the Main class and Test Case class in /src/test/java. Check it Once.

You Can use just finish(); everywhere after Activity Start for clear that Activity from Stack.

The R packages dplyr and sf import the operator %>% from the R package magrittr.

Help is available by using the following command:

?'%>%'

Of course the package must be loaded before by using e.g.

library(sf)

The documentation of the magrittr forward-pipe operator gives a good example: When functions require only one argument, x %>% f is equivalent to f(x)

Python trim method is called strip:

str.strip() #trim
str.lstrip() #ltrim
str.rstrip() #rtrim

Kotlin's way -

fun Context.bitMapFromImgUrl(imageUrl: String, callBack: (bitMap: Bitmap) -> Unit) {
    GlideApp.with(this)
        .asBitmap()
        .load(imageUrl)
        .into(object : CustomTarget<Bitmap>() {
            override fun onResourceReady(resource: Bitmap, transition: Transition<in Bitmap>?) {
                callBack(resource)
            }

            override fun onLoadCleared(placeholder: Drawable?) {
                // this is called when imageView is cleared on lifecycle call or for
                // some other reason.
                // if you are referencing the bitmap somewhere else too other than this imageView
                // clear it here as you can no longer have the bitmap
            }
        })
}

You can set values from html like this. I don't think there is a direct solution from angular yet.

 <div style="visibility: hidden;">{{activeTitle='home'}}</div>

May be I am too late but I would like to share my short and sweet answer. Please check Answer for a same problem. It will definitely help you. No more deep specifications.

If you are confident about syntax for creating table, than it may happen when you add new column in your same table, for that...

1) Uninstall from your device and run it again.

OR

2) Setting -> app -> ClearData

OR

3) Change DATABASE_VERSION in your "DatabaseHandler" class (If you have added new column than it will upgrade automatically)

public DatabaseHandler(Context context) {
    super(context, DATABASE_NAME, null, DATABASE_VERSION);
}

OR

4) Change DATABASE_NAME in your "DatabaseHandler" class (I faced same problem. But I succeed by changing DATABASE_NAME.)

You can calculate the checksum of a file by reading the binary data and using hashlib.md5().hexdigest(). A function to do this would look like the following:

def File_Checksum_Dis(dirname):
    
    if not os.path.exists(dirname):
        print(dirname+" directory is not existing");
    
    for fname in os.listdir(dirname):
        if not fname.endswith('~'):
            fnaav = os.path.join(dirname, fname);
            fd = open(fnaav, 'rb');
            data = fd.read();
            fd.close();
        
            print("-"*70);
            print("File Name is: ",fname);          
            print(hashlib.md5(data).hexdigest())
            print("-"*70);
                

You can use any of these tools:

1. adb logcat

2. adb logcat > logs.txt (you can use editors to open and search errors.)

3. eclipse logcat (If not visible in eclipse, Go to Windows->Show View->Others->Android->LogCat)

4. Android Debug Monitor or Android Device Monitor(type command monitor or open through UI)

5. Android Studio

I suggest to use Android Debug Monitor, it is good. Because eclipse hangs when too many logs are there, and through adb logcat filter and all difficult.

nvarchar with preprocessing to standardize them as much as possible. You'll probably want to extract extensions and store them in another field.

A side note, if you want to print it out, you can just say

byte b = 255;
System.out.println((b < 0 ? 256 + b : b));

Your program has no knowledge of where your VS project is, so see get path for my .exe and go ../.. to get your project's path.

Just use sudo, fast boot needs Root Permission

Visual Studio Code: Version: 1.53.2

If you are looking for the answer in 2021 (like I was), the answer is here on the Microsoft website but honestly hard to follow.

Go to Edit > Replace in Files

From there it is similar to the search funtionality for a single file.

I changed the name of a class I was using across files and this worked perfectly.

Note: If you cannot find the Replace in Files option, first click on the Search icon (magnifying glass) and then it will appear.

I tried with the following and it's worked:

release {
            debuggable true
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

It may be possible that there is no other application running. It is possible that the socket wasn't cleanly shutdown from a previous session in which case you may have to wait for a while before the TIME_WAIT expires on that socket. Unfortunately, you won't be able to use the port till that socket expires. If you can start your server after waiting for a while (a few minutes) then the problem is not due to some other application running on port 8080.

<html>
<head>
<title>Cars</title>
</head>
<body >

<h1>Cars</h1>
    <p>Name </p>
        <select id="selectBox" onchange="myFunction(value);">
            <option value="volvo" >Volvo</option>
            <option value="saab"  >Saab</option>
            <option value="mercedes">Mercedes</option>
        </select>        
<p id="result"> Price : </p>
<script>
function myFunction($value)
{       
    if($value=="volvo")
    {document.getElementById("result").innerHTML = "30L";}
    else if($value=="saab")
    {document.getElementById("result").innerHTML = "40L";}
     else if($value=="mercedes")
    {document.getElementById("result").innerHTML = "50L";}
}
</script>
</body>
</html>```

The following should work:

pip install pywin32

But it didn't for me. I fixed this by downloading and installing the exe from here:

https://github.com/mhammond/pywin32/releases

As far as i know this seems out of scope of an IDE. Copyin ,you can copy the string and then try to format it using ctrl+shift+ F Most often these multiline strings are not used hard coded,rather they shall be used from property or xml files.which can be edited at later point of time without the need for code change

I have a far more simple solution, it is working for me; it is also a workaround but might be usable and you dont have to change your settings. I assume you can use value that will never be there, then you use it on your WHERE clause

DELETE FROM MyTable WHERE MyField IS_NOT_EQUAL AnyValueNoItemOnMyFieldWillEverHave

I don't like that solution either too much, that's why I am here, but it works and it seems better than what it has been answered

Replace wouldn't replace numbers. It replaces strings only.

This should work.

function trim(str) {
    return str.toString().replace(/^\s+|\s+$/g,'');
}

If you only want to trim the string. You can simply use "str.trim()"

Handler answer in Kotlin :

1 - Create a top-level function inside a file (for example a file that contains all your top-level functions) :

fun delayFunction(function: ()-> Unit, delay: Long) {
    Handler().postDelayed(function, delay)
}

2 - Then call it anywhere you needed it :

delayFunction({ myDelayedFunction() }, 300)

Here is how to set variables in the package from code -

using Microsoft.SqlServer.Dts.Runtime;

private void Execute_Package()
    {           
        string pkgLocation = @"c:\test.dtsx";

        Package pkg;
        Application app;
        DTSExecResult pkgResults;
        Variables vars;

        app = new Application();
        pkg = app.LoadPackage(pkgLocation, null);

        vars = pkg.Variables;
        vars["A_Variable"].Value = "Some value";               

        pkgResults = pkg.Execute(null, vars, null, null, null);

        if (pkgResults == DTSExecResult.Success)
            Console.WriteLine("Package ran successfully");
        else
            Console.WriteLine("Package failed");
    }

Update:

This linked answer describes a cleaner, simpler way of doing the same thing with C# syntax.

Original post

This is Microsoft's recommended way to handle WCF client calls:

For more detail see: Expected Exceptions

try
{
    ...
    double result = client.Add(value1, value2);
    ...
    client.Close();
}
catch (TimeoutException exception)
{
    Console.WriteLine("Got {0}", exception.GetType());
    client.Abort();
}
catch (CommunicationException exception)
{
    Console.WriteLine("Got {0}", exception.GetType());
    client.Abort();
}

Additional information

So many people seem to be asking this question on WCF that Microsoft even created a dedicated sample to demonstrate how to handle exceptions:

c:\WF_WCF_Samples\WCF\Basic\Client\ExpectedExceptions\CS\client

Download the sample: C# or VB

Considering that there are so many issues involving the using statement, (heated?) Internal discussions and threads on this issue, I'm not going to waste my time trying to become a code cowboy and find a cleaner way. I'll just suck it up, and implement WCF clients this verbose (yet trusted) way for my server applications.

The Interface javax.servlet.http.HttpServletResponse from the servlet API has all the response codes in the form of int constants names SC_<description>. See http://docs.oracle.com/javaee/6/api/javax/servlet/http/HttpServletResponse.html

If you're already using jquery, I don't see why you wouldn't also be able to use a lightweight overlay plugin. Other people have already written some nice ones in jquery, so why re-invent the wheel?

It depends on your scenario (this isn't really suitable for a production environment), but here is one way:

Creating a MySQL Docker Container

This gist of it is to use a directory on your host for data persistence.

For IIS 7.5+ and Rewrite 2.0 you can use:

<system.webServer>
   <httpProtocol>
     <customHeaders>
         <add name="Access-Control-Allow-Headers" value="Origin, X-Requested-With, Content-Type, Accept" />
         <add name="Access-Control-Allow-Methods" value="POST,GET,OPTIONS,PUT,DELETE" />
     </customHeaders>
   </httpProtocol>
        <rewrite>            
            <outboundRules>
                <clear />                
                <rule name="AddCrossDomainHeader">
                    <match serverVariable="RESPONSE_Access_Control_Allow_Origin" pattern=".*" />
                    <conditions logicalGrouping="MatchAll" trackAllCaptures="true">
                        <add input="{HTTP_ORIGIN}" pattern="(http(s)?://((.+\.)?domain1\.com|(.+\.)?domain2\.com|(.+\.)?domain3\.com))" />
                    </conditions>
                    <action type="Rewrite" value="{C:0}" />
                </rule>           
            </outboundRules>
        </rewrite>
 </system.webServer>

Explaining the server variable RESPONSE_Access_Control_Allow_Origin portion:
In Rewrite you can use any string after RESPONSE_ and it will create the Response Header using the rest of the word as the header name (in this case Access-Control-Allow-Origin). Rewrite uses underscores "_" instead of dashes "-" (rewrite converts them to dashes)

Explaining the server variable HTTP_ORIGIN :
Similarly, in Rewrite you can grab any Request Header using HTTP_ as the prefix. Same rules with the dashes (use underscores "_" instead of dashes "-").

Use as.integer:

set.seed(1)
x <- runif(5, 0, 100)
x
[1] 26.55087 37.21239 57.28534 90.82078 20.16819


as.integer(x)
[1] 26 37 57 90 20

Test for class:

xx <- as.integer(x)
str(xx)
 int [1:5] 26 37 57 90 20

If you have the milliseconds since the Epoch and want to convert them to a local date using the current local timezone, you can use

LocalDate date =
    Instant.ofEpochMilli(longValue).atZone(ZoneId.systemDefault()).toLocalDate();

but keep in mind that even the system’s default time zone may change, thus the same long value may produce different result in subsequent runs, even on the same machine.

Further, keep in mind that LocalDate, unlike java.util.Date, really represents a date, not a date and time.

Otherwise, you may use a LocalDateTime:

LocalDateTime date =
    LocalDateTime.ofInstant(Instant.ofEpochMilli(longValue), ZoneId.systemDefault());

This simple implementation helps to pass data between fragments in a simple way. Think you want to pass data from 'Frgment1' to 'Fragment2'

In Fragment1(Set data to send)

 Bundle bundle = new Bundle();
 bundle.putString("key","Jhon Doe"); // set your parameteres

 Fragment2 nextFragment = new Fragment2();
 nextFragment.setArguments(bundle);

 FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
 fragmentManager.beginTransaction().replace(R.id.content_drawer, nextFragment).commit();

In Fragment2 onCreateView method (Get parameteres)

String value = this.getArguments().getString("key");//get your parameters
Toast.makeText(getActivity(), value+" ", Toast.LENGTH_LONG).show();//show data in tost

The u in u'Some String' means that your string is a Unicode string.

Q: I'm in a terrible, awful hurry and I landed here from Google Search. I'm trying to write this data to a file, I'm getting an error, and I need the dead simplest, probably flawed, solution this second.

A: You should really read Joel's Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) essay on character sets.

Q: sry no time code pls

A: Fine. try str('Some String') or 'Some String'.encode('ascii', 'ignore'). But you should really read some of the answers and discussion on Converting a Unicode string and this excellent, excellent, primer on character encoding.

The Identator plugin works to me in Brackets Release 1.13 versión 1.13.0-17696 (release 49d29a8bc) on S.O. Windows 10

Use config something like this:

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
  <servlet-name>myservlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>

<servlet>
  <servlet-name>user-webservice</servlet-name>
  <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  <load-on-startup>2</load-on-startup>
</servlet>

and then you'll need three files:

• applicationContext.xml;
• myservlet-servlet.xml; and
• user-webservice-servlet.xml.

The *-servlet.xml files are used automatically and each creates an application context for that servlet.

From the Spring documentation, 13.2. The DispatcherServlet:

The framework will, on initialization of a DispatcherServlet, look for a file named [servlet-name]-servlet.xml in the WEB-INF directory of your web application and create the beans defined there (overriding the definitions of any beans defined with the same name in the global scope).

For RHEL-based i386 distributions:

yum install ImageMagick.i386
yum install ImageMagick-devel.i386
pecl install imagick
echo "extension=imagick.so" > /etc/php.d/imagick.ini
service httpd restart

This may also work on other i386 distributions using yum package manager. For x86_64, just replace .i386 with .x86_64

In addition to the other options, in at least IntelliJ IDEA 2017 Ultimate, WebStorm 2020.2, and probably a ton of other versions, you can do it in a single shortcut.

Edit preferences, search for Select in Project View, and under Keymap, view the mapped shortcut or map one of your choice.

On the Mac, Ctrl + Option + L is not already used, and is the same shortcut as Visual Studio for Windows uses natively (Ctrl + Alt + L, so that could be a good choice.

There are two things I think you could try to develop iPhone applications.

1. You can try the Aptana mobile wep app plugin for eclipse which is nice, although still in early stage. It comes with a emulator for running the applications so this could be helpful

2. You can try cocoa

3. (Extra) Here is a nice guide I found of guy who managed to get the iPhone SDK running in ubuntu, hope this help -_-. iPhone on Ubuntu

If you are still interested, Chris Wolf made a prototype implementation of SQLite with Stored Procedures. You can find the details at his blog post: Adding Stored Procedures to SQLite

For me, something like Abdelhak Mouaamou's answer works, tested on API level 16 and 27.

Instead of using popupWindow.getContentView().getParent() and casting the result to View (which crashes on API level 16 cause there it returns a ViewRootImpl object which isn't an instance of View) I just use .getRootView() which returns a view already, so no casting required there.

Hope it helps someone :)

complete working example scrambled together from other stackoverflow posts, just copy-paste it, e.g., in the onClick listener of a button:

// inflate the layout of the popup window
LayoutInflater inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
if(inflater == null) {
    return;
}
//View popupView = inflater.inflate(R.layout.my_popup_layout, null); // this version gives a warning cause it doesn't like null as argument for the viewRoot, c.f. https://stackoverflow.com/questions/24832497 and https://stackoverflow.com/questions/26404951
View popupView = View.inflate(MyParentActivity.this, R.layout.my_popup_layout, null);

// create the popup window
final PopupWindow popupWindow = new PopupWindow(popupView,
        LinearLayout.LayoutParams.WRAP_CONTENT,
        LinearLayout.LayoutParams.WRAP_CONTENT,
        true // lets taps outside the popup also dismiss it
        );

// do something with the stuff in your popup layout, e.g.:
//((TextView)popupView.findViewById(R.id.textview_popup_helloworld))
//      .setText("hello stackoverflow");

// dismiss the popup window when touched
popupView.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            popupWindow.dismiss();
            return true;
        }
});

// show the popup window
// which view you pass in doesn't matter, it is only used for the window token
popupWindow.showAtLocation(view, Gravity.CENTER, 0, 0);
//popupWindow.setOutsideTouchable(false); // doesn't seem to change anything for me

View container = popupWindow.getContentView().getRootView();
if(container != null) {
    WindowManager wm = (WindowManager)getSystemService(Context.WINDOW_SERVICE);
    WindowManager.LayoutParams p = (WindowManager.LayoutParams)container.getLayoutParams();
    p.flags = WindowManager.LayoutParams.FLAG_DIM_BEHIND;
    p.dimAmount = 0.3f;
    if(wm != null) {
        wm.updateViewLayout(container, p);
    }
}

I understand that this error can occur because of many different reasons. In my case it was because I uninstalled WSUS service from Server Roles and the whole IIS went down. After doing a bit of research I found that uninstalling WSUS removes a few dlls which are used to do http compression. Since those dlls were missing and the IIS was still looking for them I did a reset using the following command in CMD:

appcmd set config -section:system.webServer/httpCompression /-[name='xpress']

Bingo! The problem is sorted now. Dont forget to run it as an administrator. You might also need to do "iisreset" as well. Just in case.

Hope it helps others. Cheers

Seems to work for me:

String s = "  a   b      c";
System.out.println("\""  + s.replaceAll("\\s\\s", " ") + "\"");

will print:

" a  b   c"

I think you intended to do this instead of your code:

Pattern whitespace = Pattern.compile("\\s\\s");
Matcher matcher = whitespace.matcher(s);
String result = "";
if (matcher.find()) {
    result = matcher.replaceAll(" ");
}

System.out.println(result);

This may not be the prettiest, but if you don't want to use the MessageBoxManager, (which is awesome):

 public static DialogResult DialogBox(string title, string promptText, ref string value, string button1 = "OK", string button2 = "Cancel", string button3 = null)

        button_2.DialogResult = DialogResult.Cancel;

        if (button3 != null)
            form.Controls.Add(button_3);
        if (value != null)

As mentioned by @PSIXO in a comment, this might be the problem with the dependency version of google-services. For me changing,

buildscript {
    // ...
    dependencies {
        // ...
        classpath 'com.google.gms:google-services:4.1.0'
    }
}

to

buildscript {
    // ...
    dependencies {
        // ...
        classpath 'com.google.gms:google-services:4.0.1'
    }
}

worked.There might be some problem with 4.1.0 version. Because I wasted many hours on this, I thought to write this as an answer.

http://www.youtube.com/watch?v=zLZhSSXAwxI

Just watched this video and came out with implementation. It looks easy for me to understand. Please critique this.

visited_node={root}
stack.push(root)
while(!stack.empty){
  unvisited_node = get_unvisited_adj_nodes(stack.top());
  If (unvisited_node!=null){
     stack.push(unvisited_node);  
     visited_node+=unvisited_node;
  }
  else
     stack.pop()
}

A workaround - at least for the minimum size: You can use grid to manage the frames contained in root and make them follow the grid size by setting sticky='nsew'. Then you can use root.grid_rowconfigure and root.grid_columnconfigure to set values for minsize like so:

from tkinter import Frame, Tk

class MyApp():
    def __init__(self):
        self.root = Tk()

        self.my_frame_red = Frame(self.root, bg='red')
        self.my_frame_red.grid(row=0, column=0, sticky='nsew')

        self.my_frame_blue = Frame(self.root, bg='blue')
        self.my_frame_blue.grid(row=0, column=1, sticky='nsew')

        self.root.grid_rowconfigure(0, minsize=200, weight=1)
        self.root.grid_columnconfigure(0, minsize=200, weight=1)
        self.root.grid_columnconfigure(1, weight=1)

        self.root.mainloop()

if __name__ == '__main__':
    app = MyApp()

But as Brian wrote (in 2010 :D) you can still resize the window to be smaller than the frame if you don't limit its minsize.

You can use int casting which allows the base specification.

int(b, 2)  # Convert a binary string to a decimal int.

Try the following:

strcpy(my_custom_data,"");

Arrays have a property .length that returns the number of elements.

var st =
    {
        "itema":{},
        "itemb":
        [
            {"id":"s01","cd":"c01","dd":"d01"},
            {"id":"s02","cd":"c02","dd":"d02"}
        ]
    };

st.itemb.length // 2

In .NET, the difference between Dictionary<,> and HashTable is primarily that the former is a generic type, so you get all the benefits of generics in terms of static type checking (and reduced boxing, but this isn't as big as people tend to think in terms of performance - there is a definite memory cost to boxing, though).

In the %run magic documentation you can find:

-i run the file in IPython’s namespace instead of an empty one. This is useful if you are experimenting with code written in a text editor which depends on variables defined interactively.

Therefore, supplying -i does the trick:

%run -i 'script.py'

The "correct" way to do it

Maybe the command above is just what you need, but with all the attention this question gets, I decided to add a few more cents to it for those who don't know how a more pythonic way would look like.
The solution above is a little hacky, and makes the code in the other file confusing (Where does this x variable come from? and what is the f function?).

I'd like to show you how to do it without actually having to execute the other file over and over again.
Just turn it into a module with its own functions and classes and then import it from your Jupyter notebook or console. This also has the advantage of making it easily reusable and jupyters contextassistant can help you with autocompletion or show you the docstring if you wrote one.
If you're constantly editing the other file, then autoreload comes to your help.

Your example would look like this:
script.py

import matplotlib.pyplot as plt

def myplot(f, x):
    """
    :param f: function to plot
    :type f: callable
    :param x: values for x
    :type x: list or ndarray

    Plots the function f(x).
    """
    # yes, you can pass functions around as if
    # they were ordinary variables (they are)
    plt.plot(x, f(x))
    plt.xlabel("Eje $x$",fontsize=16)
    plt.ylabel("$f(x)$",fontsize=16)
    plt.title("Funcion $f(x)$")

You could try the fnmatch module, it's got a shell-like wildcard syntax

or can use regular expressions

import re

You're forgetting to read it as binary too.

In your write part you have:

open(b"Fruits.obj","wb") # Note the wb part (Write Binary)

In the read part you have:

file = open("Fruits.obj",'r') # Note the r part, there should be a b too

So replace it with:

file = open("Fruits.obj",'rb')

And it will work :)

As for your second error, it is most likely cause by not closing/syncing the file properly.

Try this bit of code to write:

>>> import pickle
>>> filehandler = open(b"Fruits.obj","wb")
>>> pickle.dump(banana,filehandler)
>>> filehandler.close()

And this (unchanged) to read:

>>> import pickle
>>> file = open("Fruits.obj",'rb')
>>> object_file = pickle.load(file)

A neater version would be using the with statement.

For writing:

>>> import pickle
>>> with open('Fruits.obj', 'wb') as fp:
>>>     pickle.dump(banana, fp)

For reading:

>>> import pickle
>>> with open('Fruits.obj', 'rb') as fp:
>>>     banana = pickle.load(fp)

You can have many constructors as long as they take in different parameters. But the compiler putting a default constructor in is not called "constructor overriding".

Independent of your original question, you will get better performance if you capture references to local variables rather than index into your list multiple times:

AllIntegerIDs ids = new AllIntegerIDs();
ids.m_MessageID = (int)IntegerIDsSubstring[IntOffset];
ids.m_MessageType = (int)IntegerIDsSubstring[IntOffset + 1];
ids.m_ClassID = (int)IntegerIDsSubstring[IntOffset + 2];
ids.m_CategoryID = (int)IntegerIDsSubstring[IntOffset + 3];
ids.m_MessageText = MessageTextSubstring;
integerList.Add(ids);

And in your for loop:

for (int cnt3 = 0 ; cnt3 < integerList.Count ; cnt3++) //<----PROBLEM HERE
{
   AllIntegerIDs ids = integerList[cnt3];
   Console.WriteLine("{0}\t{1}\t{2}\t{3}\t{4}\n",
      ids.m_MessageID,ids.m_MessageType,ids.m_ClassID,ids.m_CategoryID, ids.m_MessageText);
}

Yes, this is possible by using worksheet events:

In the Visual Basic Editor open the worksheet you're interested in (i.e. "BigBoard") by double clicking on the name of the worksheet in the tree at the top left. Place the following code in the module:

Private Sub Worksheet_Change(ByVal Target As Range)
    If Intersect(Target, Me.Range("D2")) Is Nothing Then Exit Sub
        Application.EnableEvents = False 'to prevent endless loop
        On Error Goto Finalize 'to re-enable the events      
        MsgBox "You changed THE CELL!"
    End If
Finalize:        
    Application.EnableEvents = True
End Sub

HTML: text/html, full-stop.

XHTML: application/xhtml+xml, or only if following HTML compatbility guidelines, text/html. See the W3 Media Types Note.

XML: text/xml, application/xml (RFC 2376).

There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.

(For unregistered x- types, all bets are off, but you'd hope +xml would be respected.)

I don't think you could change the style of browsers' default alert boxes.

You need to create your own or use a simple and customizable library like xdialog. Following is a example to customize the alert box. More demos can be found here.

function show_alert() {_x000D_
    xdialog.alert("Hello! I am an alert box!");_x000D_
}

Use Form.Activate() or Form.Focus() methods.

A new byte array will automatically be initialized with all zeroes. You don't have to do anything.

The more general approach to initializing with other values, is to use the Arrays class.

import java.util.Arrays;

byte[] bytes = new byte[100];
Arrays.fill( bytes, (byte) 1 );

I have the same warning (it's make my app cannot build). When I add C function in Objective-C's .m file, But forgot to declared it at .h file.

If you're running an Apache server on your localhost (don't do this on a production server), you can also post the results to a script instead of writing it to console.

So instead of console.log, you can write:

JSONP('http://localhost/save.php', {fn: 'filename.txt', data: json});

Then save.php can do this

<?php

 $fn = $_REQUEST['fn'];
 $data = $_REQUEST['data'];

 file_put_contents("path/$fn", $data);

You could simply use

return

which does exactly the same as

return None

Your function will also return None if execution reaches the end of the function body without hitting a return statement. Returning nothing is the same as returning None in Python.

Perl one-liner similar to @jonas's awk solution:

perl -ne 'print if ! $x{$_}++' file

This variation removes trailing whitespace before comparing:

perl -lne 's/\s*$//; print if ! $x{$_}++' file

This variation edits the file in-place:

perl -i -ne 'print if ! $x{$_}++' file

This variation edits the file in-place, and makes a backup file.bak

perl -i.bak -ne 'print if ! $x{$_}++' file

To test multiple variables with one single value: if 1 in {a,b,c}:

To test multiple values with one variable: if a in {1, 2, 3}:

If you use spring this a better way

Is there any way to create form with multiple submit buttons on Spring MVC using annotations?

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().

For me the problem was the <base href="https://domain.ext/"> tag.

After removing, it was OK. Cannot really understand why it was a problem.

Just to add yet another solution :P, I went with a combination of @spheenik and @collin-anderson 's solutions.

 # Ensure that we have an ssh config with AddKeysToAgent set to true
 if [ ! -f ~/.ssh/config ] || ! cat ~/.ssh/config | grep AddKeysToAgent | grep yes > /dev/null; then
     echo "AddKeysToAgent  yes" >> ~/.ssh/config
 fi
 # Ensure a ssh-agent is running so you only have to enter keys once
 if [ ! -S ~/.ssh/ssh_auth_sock ]; then
   eval `ssh-agent`
   ln -sf "$SSH_AUTH_SOCK" ~/.ssh/ssh_auth_sock
 fi
 export SSH_AUTH_SOCK=~/.ssh/ssh_auth_sock

Could be a little more elegant but its simple and readable. This solution:

• ensures AddKeysToAgent yes is in your ssh config so keys will be automatically added upon use
• doesn't prompt you to enter any passphrases at login (again, one-time passphrase entering occurs on first use)
• silently starts an ssh-agent if it has not already started one

Comments welcome :)

I have a label on my form receiving the sum of numbers from Column D in Sheet1. I am only interested in rows 2 to 50, you can use a row counter if your row count is dynamic. I have some blank entries as well in column D and they are ignored.

Me.lblRangeTotal = Application.WorksheetFunction.Sum(ThisWorkbook.Sheets("Sheet1").Range("D2:D50"))

I don't have a high enough reputation to comment on Gavin Simpson's answer, but I wanted to warn that there seems to be a difference in the default treatment of missing values between the standard syntax and the formula syntax for aggregate.

#Create some data with missing values 
a<-data.frame(day=rep(1,5),hour=c(1,2,3,3,4),val=c(1,NA,3,NA,5))
  day hour val
1   1    1   1
2   1    2  NA
3   1    3   3
4   1    3  NA
5   1    4   5

#Standard syntax
aggregate(a$val,by=list(day=a$day,hour=a$hour),mean,na.rm=T)
  day hour   x
1   1    1   1
2   1    2 NaN
3   1    3   3
4   1    4   5

#Formula syntax.  Note the index for hour 2 has been silently dropped.
aggregate(val ~ hour + day,data=a,mean,na.rm=T)
  hour day val
1    1   1   1
2    3   1   3
3    4   1   5

Liviu's answer was extremely helpful for me. Hope this is not bad form but i made a fiddle that may help someone else out in the future.

Two important pieces that are needed are:

    $scope.entities = [{
    "title": "foo",
    "id": 1
}, {
    "title": "bar",
    "id": 2
}, {
    "title": "baz",
    "id": 3
}];
$scope.selected = [];

All the existing answers are imperfect (IMO) and either make assumptions about the desired output or don't provide flexibility for the desired output.

Based on the examples from the OP, and the OP's stated expected answers, I think these are the answers you are looking for (plus some additional examples that make it easy to extrapolate).

(This only requires base R and doesn't require zoo or lubridate)

Convert to Datetime Objects

date_strings = c("14.01.2013", "26.03.2014")
datetimes = strptime(date_strings, format = "%d.%m.%Y") # convert to datetime objects

Difference in Days

You can use the diff in days to get some of our later answers

diff_in_days = difftime(datetimes[2], datetimes[1], units = "days") # days
diff_in_days
#Time difference of 435.9583 days

Difference in Weeks

Difference in weeks is a special case of units = "weeks" in difftime()

diff_in_weeks = difftime(datetimes[2], datetimes[1], units = "weeks") # weeks
diff_in_weeks
#Time difference of 62.27976 weeks

Note that this is the same as dividing our diff_in_days by 7 (7 days in a week)

as.double(diff_in_days)/7
#[1] 62.27976

Difference in Years

With similar logic, we can derive years from diff_in_days

diff_in_years = as.double(diff_in_days)/365 # absolute years
diff_in_years
#[1] 1.194406

You seem to be expecting the diff in years to be "1", so I assume you just want to count absolute calendar years or something, which you can easily do by using floor()

# get desired output, given your definition of 'years'
floor(diff_in_years)
#[1] 1

Difference in Quarters

# get desired output for quarters, given your definition of 'quarters'
floor(diff_in_years * 4)
#[1] 4

Difference in Months

Can calculate this as a conversion from diff_years

# months, defined as absolute calendar months (this might be what you want, given your question details)
months_diff = diff_in_years*12
floor(month_diff)
#[1] 14

I know this question is old, but given that I still had to solve this problem just now, I thought I would add my answers. Hope it helps.

From Wikipedia:

According to the 1999 ISO C standard (C99), size_t is an unsigned integer type of at least 16 bit (see sections 7.17 and 7.18.3).

size_tis an unsigned data type defined by several C/C++ standards, e.g. the C99 ISO/IEC 9899 standard, that is defined in stddef.h.1 It can be further imported by inclusion of stdlib.h as this file internally sub includes stddef.h.

This type is used to represent the size of an object. Library functions that take or return sizes expect them to be of type or have the return type of size_t. Further, the most frequently used compiler-based operator sizeof should evaluate to a constant value that is compatible with size_t.

As an implication, size_t is a type guaranteed to hold any array index.

ssh + key authentication is more reliable way than https + credential.helper

You can configure to use SSH instead of HTTPS for all the repositories as follows:

git config --global url.ssh://[email protected]/.insteadOf https://github.com/

url.<base>.insteadOf is documented here.

The difference is that the background shorthand property sets several background-related properties. It sets them all, even if you only specify e.g. a color value, since then the other properties are set to their initial values, e.g. background-image to none.

This does not mean that it would always override any other settings for those properties. This depends on the cascade according to the usual, generally misunderstood rules.

In practice, the shorthand tends to be somewhat safer. It is a precaution (not complete, but useful) against accidentally getting some unexpected background properties, such as a background image, from another style sheet. Besides, it’s shorter. But you need to remember that it really means “set all background properties”.

For using "overflow: scroll" you must set "display:block" on thead and tbody. And that messes up column widths between them. But then you can clone the thead row with Javascript and paste it in the tbody as a hidden row to keep the exact col widths.

$('.myTable thead > tr').clone().appendTo('.myTable tbody').addClass('hidden-to-set-col-widths');

http://jsfiddle.net/Julesezaar/mup0c5hk/

<table class="myTable">
    <thead>
        <tr>
            <td>Problem</td>
            <td>Solution</td>
            <td>blah</td>
            <td>derp</td>
        </tr>
    </thead>
    <tbody></tbody>
</table>
<p>
  Some text to here
</p>

The css:

table {
  background-color: #aaa;
  width: 100%;
}

thead,
tbody {
  display: block; // Necessary to use overflow: scroll
}

tbody {
  background-color: #ddd;
  height: 150px;
  overflow-y: scroll;
}

tbody tr.hidden-to-set-col-widths,
tbody tr.hidden-to-set-col-widths td {
  visibility: hidden;
  height: 0;
  line-height: 0;
  padding-top: 0;
  padding-bottom: 0;
}

It is correct that rm –rf . will remove everything in the current directly including any subdirectories and their content. The single dot (.) means the current directory. be carefull not to do rm -rf .. since the double dot (..) means the previous directory.

This being said, if you are like me and have multiple terminal windows open at the same time, you'd better be safe and use rm -ir . Lets look at the command arguments to understand why.

First, if you look at the rm command man page (man rm under most Unix) you notice that –r means "remove the contents of directories recursively". So, doing rm -r . alone would delete everything in the current directory and everything bellow it.

In rm –rf . the added -f means "ignore nonexistent files, never prompt". That command deletes all the files and directories in the current directory and never prompts you to confirm you really want to do that. -f is particularly dangerous if you run the command under a privilege user since you could delete the content of any directory without getting a chance to make sure that's really what you want.

On the otherhand, in rm -ri . the -i that replaces the -f means "prompt before any removal". This means you'll get a chance to say "oups! that's not what I want" before rm goes happily delete all your files.

In my early sysadmin days I did an rm -rf / on a system while logged with full privileges (root). The result was two days passed a restoring the system from backups. That's why I now employ rm -ri now.

Try the following

double hours = (b-a).TotalHours;

If you just want the hour difference excluding the difference in days you can use the following

int hours = (b-a).Hours;

The difference between these two properties is mainly seen when the time difference is more than 1 day. The Hours property will only report the actual hour difference between the two dates. So if two dates differed by 100 years but occurred at the same time in the day, hours would return 0. But TotalHours will return the difference between in the total amount of hours that occurred between the two dates (876,000 hours in this case).

The other difference is that TotalHours will return fractional hours. This may or may not be what you want. If not, Math.Round can adjust it to your liking.

I had the same problem, tried all the solutions but nothing worked. The problem is with Windows 7 installed is 64 bit and all the software that you are installing should be 32 bit. Android SDK itself is 32 bit and it identifies only 32 bit JDK. So install following software.

1. JDK (32 bit)
2. Android SDK (while installing SDK, make sure install it in directory other than "C:\Program Files (x86)", more probably in other drive or in the directory where Eclipse is extracted)
3. Eclipse (32 bit) and finally ADT.

I tried it and all works fine.

As said above you can put it inside a ScrollView... and if you want the Scroll View to be horizontal put it inside HorizontalScrollView... and if you want your component (or layout) to support both put inside both of them like this:

  <HorizontalScrollView>
        <ScrollView>
            <!-- SOME THING -->
        </ScrollView>
    </HorizontalScrollView>

and with setting the layout_width and layout_height ofcourse.

You need a parameter with Direction set to ParameterDirection.ReturnValue in code but no need to add an extra parameter in SP. Try this

  SqlParameter returnParameter = cmd.Parameters.Add("RetVal", SqlDbType.Int);
  returnParameter.Direction = ParameterDirection.ReturnValue;
  cmd.ExecuteNonQuery();

  int id = (int) returnParameter.Value;

I solved this problem like this.

1. setImage to UIImageView (with UIViewContentModeScaleAspectFit)
2. get imageSize (CGSize imageSize = imageView.image.size)
3. UIImageView resize. [imageView sizeThatFits:imageSize]
4. move position where you want.

I wanted to put UIView on the top center of UICollectionViewCell. so, I used this function.

- (void)setImageToCenter:(UIImageView *)imageView
{
    CGSize imageSize = imageView.image.size;
    [imageView sizeThatFits:imageSize];
    CGPoint imageViewCenter = imageView.center;
     imageViewCenter.x = CGRectGetMidX(self.contentView.frame);
    [imageView setCenter:imageViewCenter];
}

It works for me.

Based on Anuga answer I have extended it to multiple images.

Keep track of the rotation angle of the image as an attribute of the image.

function rotate(image) {_x000D_
  let rotateAngle = Number(image.getAttribute("rotangle")) + 90;_x000D_
  image.setAttribute("style", "transform: rotate(" + rotateAngle + "deg)");_x000D_
  image.setAttribute("rotangle", "" + rotateAngle);_x000D_
}

.rotater {_x000D_
  transition: all 0.3s ease;_x000D_
  border: 0.0625em solid black;_x000D_
  border-radius: 3.75em;_x000D_
}

Edit

Removed the modulo, looks strange.

Lookarounds are zero width assertions. They check for a regex (towards right or left of the current position - based on ahead or behind), succeeds or fails when a match is found (based on if it is positive or negative) and discards the matched portion. They don't consume any character - the matching for regex following them (if any), will start at the same cursor position.

Read regular-expression.info for more details.

• Positive lookahead:

Syntax:

(?=REGEX_1)REGEX_2

Match only if REGEX_1 matches; after matching REGEX_1, the match is discarded and searching for REGEX_2 starts at the same position.

example:

(?=[a-z0-9]{4}$)[a-z]{1,2}[0-9]{2,3}

REGEX_1 is [a-z0-9]{4}$ which matches four alphanumeric chars followed by end of line.
REGEX_2 is [a-z]{1,2}[0-9]{2,3} which matches one or two letters followed by two or three digits.

REGEX_1 makes sure that the length of string is indeed 4, but doesn't consume any characters so that search for REGEX_2 starts at the same location. Now REGEX_2 makes sure that the string matches some other rules. Without look-ahead it would match strings of length three or five.

• Negative lookahead

Syntax:

(?!REGEX_1)REGEX_2

Match only if REGEX_1 does not match; after checking REGEX_1, the search for REGEX_2 starts at the same position.

example:

(?!.*\bFWORD\b)\w{10,30}$

The look-ahead part checks for the FWORD in the string and fails if it finds it. If it doesn't find FWORD, the look-ahead succeeds and the following part verifies that the string's length is between 10 and 30 and that it contains only word characters a-zA-Z0-9_

Look-behind is similar to look-ahead: it just looks behind the current cursor position. Some regex flavors like javascript doesn't support look-behind assertions. And most flavors that support it (PHP, Python etc) require that look-behind portion to have a fixed length.

• Atomic groups basically discards/forgets the subsequent tokens in the group once a token matches. Check this page for examples of atomic groups

You need to have a doGet method as:

public void doGet(HttpServletRequest request,
        HttpServletResponse response)
throws IOException, ServletException
{
    response.setContentType("text/html");
    PrintWriter out = response.getWriter();

    out.println("<html>");
    out.println("<head>");
    out.println("<title>Hola</title>");
    out.println("</head>");
    out.println("<body bgcolor=\"white\">");
    out.println("</body>");
    out.println("</html>");
}

Use finish like this:

Intent i = new Intent(Main_Menu.this, NextActivity.class);
finish();  //Kill the activity from which you will go to next activity 
startActivity(i);

FLAG_ACTIVITY_NO_HISTORY you can use in case for the activity you want to finish. For exampe you are going from A-->B--C. You want to finish activity B when you go from B-->C so when you go from A-->B you can use this flag. When you go to some other activity this activity will be automatically finished.

To learn more on using Intent.FLAG_ACTIVITY_NO_HISTORY read: http://developer.android.com/reference/android/content/Intent.html#FLAG_ACTIVITY_NO_HISTORY

I know this is a late answer, but I hope this will help someone.

Consider that you have defined following classes in a css file 'primary', 'font-i', 'font-xl'

• The first step would be to import the CSS file.
• Then

<h3 class = {` ${'primary'} ${'font-i'} font-xl`}> HELLO WORLD </h3>

would do the trick!

When using Node.js, you can retrieve environment variables by key from the process.env object:

for example

var mode   = process.env.NODE_ENV;
var apiKey = process.env.apiKey; // '42348901293989849243'

Here is the answer that will explain setting environment variables in node.js

I think the following function can help to have scroll coordinate values:

const getScrollCoordinate = (el = window) => ({
  x: el.pageXOffset || el.scrollLeft,
  y: el.pageYOffset || el.scrollTop,
});

I got this idea from this answer with a little change.

Most of the answers don't include good implementation of childViewControllerForStatusBarStyle method for UINavigationController. According to my experience you should handle such cases as when transparent view controller is presented over navigation controller. In these cases you should pass control to your modal controller (visibleViewController), but not when it's disappearing.

override var childViewControllerForStatusBarStyle: UIViewController? {
  var childViewController = visibleViewController
  if let controller = childViewController, controller.isBeingDismissed {
    childViewController = topViewController
  }
  return childViewController?.childViewControllerForStatusBarStyle ?? childViewController
}

With iOS 13.1.2, orientation always return 0 until device is rotated. I need to call UIDevice.current.beginGeneratingDeviceOrientationNotifications() before any rotation event occurs to get actual rotation.

This works for me:

pip install numpy --upgrade

For Mac -Chrome browser

public class MultipleBrowser {

    public WebDriver driver= null;
    String browser="mozilla";
    String url="https://www.omnicard.com";

    @BeforeMethod
    public void LaunchBrowser() {

      if(browser.equalsIgnoreCase("mozilla"))
          driver= new FirefoxDriver();
      else if(browser.equalsIgnoreCase("safari"))
          driver= new SafariDriver();
      else if(browser.equalsIgnoreCase("chrome"))
          System.setProperty("webdriver.chrome.driver","/Users/mhossain/Desktop/chromedriver");
          driver= new ChromeDriver();   
          driver.manage().timeouts().implicitlyWait(4, TimeUnit.SECONDS);
          driver.navigate().to(url);
          //driver.manage().deleteAllCookies();

  }

As Chris said before me, just an a should override. For example:

a { color:red; }
a:hover { color:blue; }
.nav a { color:green; }

In this instance the .nav a would ALWAYS be green, the :hover wouldn't apply to it.

If there's some other rule affecting it, you COULD use !important, but you shouldn't. It's a bad habit to fall into.

.nav a { color:green !important; } /*I'm a bad person and shouldn't use !important */

Then it'll always be green, irrelevant of any other rule.

The best way is you should destroy the slick slider after reinitializing it.

function slickCarousel() {
  $('.skills_section').slick({
    infinite: true,
    slidesToShow: 3,
    slidesToScroll: 1
  });
