Programs & Examples On #Powerpoint 2007

Here is the simplest way:

#!/bin/sh
cat -

Usage:

$ echo test | sh my_script.sh
test

To assign stdin to the variable, you may use: STDIN=$(cat -) or just simply STDIN=$(cat) as operator is not necessary (as per @mklement0 comment).

To parse each line from the standard input, try the following script:

#!/bin/bash
while IFS= read -r line; do
  printf '%s\n' "$line"
done

To read from the file or stdin (if argument is not present), you can extend it to:

#!/bin/bash
file=${1--} # POSIX-compliant; ${1:--} can be used either.
while IFS= read -r line; do
  printf '%s\n' "$line" # Or: env POSIXLY_CORRECT=1 echo "$line"
done < <(cat -- "$file")

Notes:

^{- read -r - Do not treat a backslash character in any special way. Consider each backslash to be part of the input line.}

^{- Without setting IFS, by default the sequences of Space and Tab at the beginning and end of the lines are ignored (trimmed).}

^{- Use printf instead of echo to avoid printing empty lines when the line consists of a single -e, -n or -E. However there is a workaround by using env POSIXLY_CORRECT=1 echo "$line" which executes your external GNU echo which supports it. See: How do I echo "-e"?}

I needed a solution to convert columns to rows in Microsoft SQL Server, without knowing the colum names (used in trigger) and without dynamic sql (dynamic sql is too slow for use in a trigger).

I finally found this solution, which works fine:

SELECT
    insRowTbl.PK,
    insRowTbl.Username,
    attr.insRow.value('local-name(.)', 'nvarchar(128)') as FieldName,
    attr.insRow.value('.', 'nvarchar(max)') as FieldValue 
FROM ( Select      
          i.ID as PK,
          i.LastModifiedBy as Username,
          convert(xml, (select i.* for xml raw)) as insRowCol
       FROM inserted as i
     ) as insRowTbl
CROSS APPLY insRowTbl.insRowCol.nodes('/row/@*') as attr(insRow)

As you can see, I convert the row into XML (Subquery select i,* for xml raw, this converts all columns into one xml column)

Then I CROSS APPLY a function to each XML attribute of this column, so that I get one row per attribute.

Overall, this converts columns into rows, without knowing the column names and without using dynamic sql. It is fast enough for my purpose.

(Edit: I just saw Roman Pekar answer above, who is doing the same. I used the dynamic sql trigger with cursors first, which was 10 to 100 times slower than this solution, but maybe it was caused by the cursor, not by the dynamic sql. Anyway, this solution is very simple an universal, so its definitively an option).

I am leaving this comment at this place, because I want to reference this explanation in my post about the full audit trigger, that you can find here: https://stackoverflow.com/a/43800286/4160788

After looking at your phpinfo() output, it appears the mysql extensions are not being loaded. I suspect you might be editing the wrong php.ini file (there might be multiple copies). Make sure you are editing the php file at C:\php\php.ini (also check to make sure there is no second copy in C:\Windows).

Also, you should check your Apache logs for errors (should be in the \logs\ directory in your Apache install.

If you haven't read the below, I would take a look at the comments section, because it seems like a lot of people experience quirks with setting this up. A few commenters offer solutions they used to get it working.

http://php.net/manual/en/install.windows.extensions.php

Another common solution seems to be to copy libmysql.dll and php_mysql.dll from c:\PHP to C:\Windows\System32.

use move then move <file or folder> <destination directory>

If you want all the configuration files loaded, this is will tell you:

php -i | grep "\.ini"

Some systems load things from more than one ini file. On my ubuntu system, it looks like this:

$  php -i | grep "\.ini"
Configuration File (php.ini) Path => /etc/php5/cli
Loaded Configuration File => /etc/php5/cli/php.ini
Scan this dir for additional .ini files => /etc/php5/cli/conf.d
additional .ini files parsed => /etc/php5/cli/conf.d/apc.ini,
/etc/php5/cli/conf.d/curl.ini,
/etc/php5/cli/conf.d/gd.ini,
/etc/php5/cli/conf.d/mcrypt.ini,
/etc/php5/cli/conf.d/memcache.ini,
/etc/php5/cli/conf.d/mysql.ini,
/etc/php5/cli/conf.d/mysqli.ini,
/etc/php5/cli/conf.d/pdo.ini,
/etc/php5/cli/conf.d/pdo_mysql.ini

Without having Visual Studio, you can grab Nuget from: http://nuget.org/nuget.exe

For command-line executions using this, check out: http://docs.nuget.org/docs/reference/command-line-reference

With respect to Powershell, just copy the nuget.exe to the machine. No installation required, just execute it using commands from the above documentation.

To execute more Maven builds from one script you shall use the Windows call function in the following way:

call mvn install:install-file -DgroupId=gdata -DartifactId=base -Dversion=1.0 -Dfile=gdata-base-1.0.jar  -Dpackaging=jar -DgeneratePom=true
call mvn install:install-file -DgroupId=gdata -DartifactId=blogger -Dversion=2.0 -Dfile=gdata-blogger-2.0.jar  -Dpackaging=jar -DgeneratePom=true
call mvn install:install-file -DgroupId=gdata -DartifactId=blogger-meta -Dversion=2.0 -Dfile=gdata-blogger-meta-2.0.jar  -Dpackaging=jar -DgeneratePom=true

Edit: Just realized that @Chinmoy was getting at basically the same thing, but I think I may have done a better job ELI5 :)

If you're using a flavor of Spring Data to help persist / fetch things from whatever kind of Repository you've defined, you can probably have your JPA provider do this for you via some clever tricks with method names in your Repository interface class. Allow me to explain.

(As a disclaimer, I just a few moments ago did/still am figuring this out for myself.)

For example, if I am storing Tokens in my database, I might have an entity class that looks like this:

@Data // << Project Lombok convenience annotation
@Entity
public class Token {
    @Id
    @Column(name = "TOKEN_ID")
    private String tokenId;

    @Column(name = "TOKEN")
    private String token;

    @Column(name = "EXPIRATION")
    private String expiration;

    @Column(name = "SCOPE")
    private String scope;
}

And I probably have a CrudRepository<K,V> interface defined like this, to give me simple CRUD operations on that Repository for free.

@Repository
// CrudRepository<{Entity Type}, {Entity Primary Key Type}>
public interface TokenRepository extends CrudRepository<Token, String> { }

And when I'm looking up one of these tokens, my purpose might be checking the expiration or scope, for example. In either of those cases, I probably don't have the tokenId handy, but rather just the value of a token field itself that I want to look up.

To do that, you can add an additional method to your TokenRepository interface in a clever way to tell your JPA provider that the value you're passing in to the method is not the tokenId, but the value of another field within the Entity class, and it should take that into account when it is generating the actual SQL that it will run against your database.

@Repository
// CrudRepository<{Entity Type}, {Entity Primary Key Type}>
public interface TokenRepository extends CrudRepository<Token, String> { 
    List<Token> findByToken(String token);
}

I read about this on the Spring Data R2DBC docs page, and it seems to be working so far within a SpringBoot 2.x app storing in an embedded H2 database.

That error occurs when you want to add a foreign key with values that don't exist in the primary key of the parent table. You must be sure that the new foreign key UserID in table2 has values that exist in the table1 primary key, sometimes by default it is null or equal to 0.

You could first update all the fields of the foreign key in table2 with a value that exists in the primary key of table1.

update table2 set UserID = 1 where UserID is null

If you want to add different UserIDs you must modify each row with the values you want.

Another easy way is to have your own view class and add a property of the view controller in the view class. Usually the view controller creates the view and that is where the controller can set itself to the property. Basically it is instead of searching around (with a bit of hacking) for the controller, having the controller to set itself to the view - this is simple but makes sense because it is the controller that "controls" the view.

In Java 8 I would use:

Set<String> set = Stream.of("a", "b").collect(Collectors.toSet());

This gives you a mutable Set pre-initialized with "a" and "b". Note that while in JDK 8 this does return a HashSet, the specification doesn't guarantee it, and this might change in the future. If you specifically want a HashSet, do this instead:

Set<String> set = Stream.of("a", "b")
                        .collect(Collectors.toCollection(HashSet::new));

long x = 3;
int y = (int) x;

but that assumes that the long can be represented as an int, you do know the difference between the two?

See this. Your code would be something like the following:

from django.db.models import Max
# Generates a "SELECT MAX..." query
Argument.objects.aggregate(Max('rating')) # {'rating__max': 5}

You can also use this on existing querysets:

from django.db.models import Max
args = Argument.objects.filter(name='foo') # or whatever arbitrary queryset
args.aggregate(Max('rating')) # {'rating__max': 5}

If you need the model instance that contains this max value, then the code you posted is probably the best way to do it:

arg = args.order_by('-rating')[0]

Note that this will error if the queryset is empty, i.e. if no arguments match the query (because the [0] part will raise an IndexError). If you want to avoid that behavior and instead simply return None in that case, use .first():

arg = args.order_by('-rating').first() # may return None

package will add packaged jar or war to your target folder, We can check it when, we empty the target folder (using mvn clean) and then run mvn package.
install will do all the things that package does, additionally it will add packaged jar or war in local repository as well. We can confirm it by checking in your .m2 folder.

Smoothly scroll to the proper position (2019)

Get correct y coordinate and use window.scrollTo({top: y, behavior: 'smooth'})

const id = 'anchorName2';
const yourElement = document.getElementById(id);
const y = yourElement.getBoundingClientRect().top + window.pageYOffset;

window.scrollTo({top: y, behavior: 'smooth'});

With offset

scrollIntoView is a good option too but it may not works perfectly in some cases. For example when you need additional offset. With scrollTo you just need to add that offset like this:

const yOffset = -10; 

window.scrollTo({top: y + yOffset, behavior: 'smooth'});

You can log the stack trace without an exception.

https://docs.python.org/3/library/logging.html#logging.Logger.debug

The second optional keyword argument is stack_info, which defaults to False. If true, stack information is added to the logging message, including the actual logging call. Note that this is not the same stack information as that displayed through specifying exc_info: The former is stack frames from the bottom of the stack up to the logging call in the current thread, whereas the latter is information about stack frames which have been unwound, following an exception, while searching for exception handlers.

Example:

>>> import logging
>>> logging.basicConfig(level=logging.DEBUG)
>>> logging.getLogger().info('This prints the stack', stack_info=True)
INFO:root:This prints the stack
Stack (most recent call last):
  File "<stdin>", line 1, in <module>
>>>

Can also be done this way..

regex=re.compile('^hello')

## THIS WAY YOU CAN CHECK FOR MULTIPLE STRINGS
## LIKE
## regex=re.compile('^hello|^john|^world')

if re.match(regex, somestring):
    print("Yes")

Setting this attribute to ObjectMapper instance works,

objectMapper.enable(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY);

You need to add tabs plugin to your code

<script type="text/javascript" src="assets/twitterbootstrap/js/bootstrap-tab.js"></script>

Well, it didn't work. I made some tests and it started working when:

1. moved (updated to 1.7) jQuery script to <head> section
2. added data-toggle="tab" to links and id for <ul> tab element
3. changed $(".tabs").tabs(); to $("#tabs").tab();
4. and some other things that shouldn't matter

Here's a code

<!DOCTYPE html>
<html lang="en">

<link href="../bootstrap/css/bootstrap.css" rel="stylesheet">

        <div class="tab-pane" id="yellow">
            <h1>Yellow</h1>

        </div>
        <div class="tab-pane" id="green">
            <h1>Green</h1>
            <p>green green green green green</p>
        </div>
        <div class="tab-pane" id="blue">
            <h1>Blue</h1>
            <p>blue blue blue blue blue</p>
        </div>
    </div>
</div>


<script type="text/javascript">
    jQuery(document).ready(function ($) {
        $('#tabs').tab();
    });
</script>    
</div> <!-- container -->


<script type="text/javascript" src="../bootstrap/js/bootstrap.js"></script>

</html>

Take a pointer to the first element instead:

process_data (&something [0]);

$(".thumbs").hover(
    function(){
        if (!$(this).hasClass("selected")) {
            $(this).stop().fadeTo("normal", 1.0);
        }
    },
    function(){
        if (!$(this).hasClass("selected")) {
            $(this).stop().fadeTo("slow", 0.3); 
        }           
    }
);

Putting an if inside of each part of the hover will allow you to change the select class dynamically and the hover will still work.

$(".thumbs").click(function() {
    $(".thumbs").each(function () {
        if ($(this).hasClass("selected")) {
            $(this).removeClass("selected");
            $(this).hover();
        }
    });                 
    $(this).addClass("selected");                   
});

As an example I've also attached a click handler to switch the selected class to the clicked item. Then I fire the hover event on the previous item to make it fade out.

Here is another idea that allow you to affect other elements without considering any specific selector and by only using the :hover state of the main element.

For this, I will rely on the use of custom properties (CSS variables). As we can read in the specification:

Custom properties are ordinary properties, so they can be declared on any element, are resolved with the normal inheritance and cascade rules ...

The idea is to define custom properties within the main element and use them to style child elements and since these properties are inherited we simply need to change them within the main element on hover.

Here is an example:

#container {_x000D_
  width: 200px;_x000D_
  height: 30px;_x000D_
  border: 1px solid var(--c);_x000D_
  --c:red;_x000D_
}_x000D_
#container:hover {_x000D_
  --c:blue;_x000D_
}_x000D_
#container > div {_x000D_
  width: 30px;_x000D_
  height: 100%;_x000D_
  background-color: var(--c);_x000D_
}

<div id="container">_x000D_
  <div>_x000D_
  </div>_x000D_
</div>

Why this can be better than using specific selector combined with hover?

I can provide at least 2 reasons that make this method a good one to consider:

1. If we have many nested elements that share the same styles, this will avoid us complex selector to target all of them on hover. Using Custom properties, we simply change the value when hovering on the parent element.
2. A custom property can be used to replace a value of any property and also a partial value of it. For example we can define a custom property for a color and we use it within a border, linear-gradient, background-color, box-shadow etc. This will avoid us reseting all these properties on hover.

Here is a more complex example:

.container {_x000D_
  --c:red;_x000D_
  width:400px;_x000D_
  display:flex;_x000D_
  border:1px solid var(--c);_x000D_
  justify-content:space-between;_x000D_
  padding:5px;_x000D_
  background:linear-gradient(var(--c),var(--c)) 0 50%/100% 3px no-repeat;_x000D_
}_x000D_
.box {_x000D_
  width:30%;_x000D_
  background:var(--c);_x000D_
  box-shadow:0px 0px 5px var(--c);_x000D_
  position:relative;_x000D_
}_x000D_
.box:before {_x000D_
  content:"A";_x000D_
  display:block;_x000D_
  width:15px;_x000D_
  margin:0 auto;_x000D_
  height:100%;_x000D_
  color:var(--c);_x000D_
  background:#fff;_x000D_
}_x000D_
_x000D_
/*Hover*/_x000D_
.container:hover {_x000D_
  --c:blue;_x000D_
}

<div class="container">_x000D_
<div class="box"></div>_x000D_
<div class="box"></div>_x000D_
</div>

As we can see above, we only need one CSS declaration in order to change many properties of different elements.

Here's a similar answer using using a => style function:

var data = [1,2,3,4];
data.forEach( (item, i, self) => self[i] = item + 10 );

gives the result:

[11,12,13,14]

The self parameter isn't strictly necessary with the arrow style function, so

data.forEach( (item,i) => data[i] = item + 10);

also works.

As said before, with JPA, in order to have the chance to have extra columns, you need to use two OneToMany associations, instead of a single ManyToMany relationship. You can also add a column with autogenerated values; this way, it can work as the primary key of the table, if useful.

For instance, the implementation code of the extra class should look like that:

@Entity
@Table(name = "USER_SERVICES")
public class UserService{

    // example of auto-generated ID
    @Id
    @Column(name = "USER_SERVICES_ID", nullable = false)
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long userServiceID;



    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "USER_ID")
    private User user;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "SERVICE_ID")
    private Service service;



    // example of extra column
    @Column(name="VISIBILITY")    
    private boolean visibility;



    public long getUserServiceID() {
        return userServiceID;
    }


    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }

    public Service getService() {
        return service;
    }

    public void setService(Service service) {
        this.service = service;
    }

    public boolean getVisibility() {
        return visibility;
    }

    public void setVisibility(boolean visibility) {
        this.visibility = visibility;
    }

}

The accepted answer is the correct one.

OTOH, the way I previously solved this was to add the following to all projects:

test.onlyIf { ! Boolean.getBoolean('skip.tests') }

Run the build with -Dskip.tests=true and all test tasks will be skipped.

A Popen object has a .wait() method exactly defined for this: to wait for the completion of a given subprocess (and, besides, for retuning its exit status).

If you use this method, you'll prevent that the process zombies are lying around for too long.

(Alternatively, you can use subprocess.call() or subprocess.check_call() for calling and waiting. If you don't need IO with the process, that might be enough. But probably this is not an option, because your if the two subprocesses seem to be supposed to run in parallel, which they won't with (check_)call().)

If you have several subprocesses to wait for, you can do

exit_codes = [p.wait() for p in p1, p2]

which returns as soon as all subprocesses have finished. You then have a list of return codes which you maybe can evaluate.

ViewBag is server side code.
Javascript is client side code.

You can't really connect them.

You can do something like this:

var x = $('#' + '@(ViewBag.CC)').val();

But it will get parsed on the server, so you didn't really connect them.

write a cloud function to and update the node count.

// below function to get the given node count.
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);

exports.userscount = functions.database.ref('/users/')
    .onWrite(event => {

      console.log('users number : ', event.data.numChildren());


      return event.data.ref.parent.child('count/users').set(event.data.numChildren());
    }); 

Refer :https://firebase.google.com/docs/functions/database-events

root--| |-users ( this node contains all users list) |
|-count |-userscount : (this node added dynamically by cloud function with the user count)

You can give below code a try,

public void multiArrayCopy(int[][] source,int[][] destination){
destination=source.clone();}

Hope it works.

For Typescript 2.x.x you should do it in a following way(using type guard):

tl;dr

function isDefined<T>(value: T | undefined | null): value is T {
  return <T>value !== undefined && <T>value !== null;
}

Why?

In this way isDefined() will respect variable's type and the following code would know take this check in account.

Example 1 - basic check:

function getFoo(foo: string): void { 
  //
}

function getBar(bar: string| undefined) {   
  getFoo(bar); //ERROR: "bar" can be undefined
  if (isDefined(bar)) {
    getFoo(bar); // Ok now, typescript knows that "bar' is defined
  }
}

Example 2 - types respect:

function getFoo(foo: string): void { 
  //
}

function getBar(bar: number | undefined) {
  getFoo(bar); // ERROR: "number | undefined" is not assignable to "string"
  if (isDefined(bar)) {
    getFoo(bar); // ERROR: "number" is not assignable to "string", but it's ok - we know it's number
  }
}

Much easier way:

$('#test').css('textTransform', 'capitalize');

I have to give @Dementic some credit for leading me down the right path. Far simpler than whatever you guys are proposing.

I had this issue when tried to run a 32-bit OS with more than 3584 MB of RAM allocated for it. Setting the guest OS RAM to 3584 MB and less helped.

But i ended just enabling the flag in BIOS nevertheless.

You may use cdecl utility or its online versions, like https://cdecl.org/

For example:

void (* x)(int (*[])()); is a declare x as pointer to function (array of pointer to function returning int) returning void

You can use whichever you like in T-SQL. The documentation says they both function the same way. I prefer !=, because it reads "not equal" to my (C/C++/C# based) mind, but database gurus seem to prefer <>.

a quick way to see your errors whilst testing:

$error= $st->errorInfo();
echo $error[2];

i got the same problem, i used malloc over n over again in a loop for adding new char *string data. i faced the same problem, but after releasing the allocated memory void free() problem were sorted

Something like:

$('#test').append('<div id="newdiv">Hello</div>').hide().show('slow');

should do it?

Edit: sorry, mistake in code and took Matt's suggestion on board too.

I would use a ByteArrayOutputStream. And on finish you can call:

new String( baos.toByteArray(), codepage );

or better:

baos.toString( codepage );

For the String constructor, the codepage can be a String or an instance of java.nio.charset.Charset. A possible value is java.nio.charset.StandardCharsets.UTF_8.

The method toString() accepts only a String as a codepage parameter (stand Java 8).

For Windows 10 x64 and Python:

Open a Visual Studio x64 command prompt, and use dumpbin:

dumpbin /dependents [Python Module DLL or PYD file]

If you do not have Visual Studio installed, it is possible to download dumpbin elsewhere, or use another utility such as Dependency Walker.

Note that all other answers (to date) are simply random stabs in the dark, whereas this method is closer to a sniper rifle with night vision.

Case study 1

1. I switched on Address Sanitizer for a Python module that I wrote using C++ using MSVC and CMake.

2. It was giving this error: ImportError: DLL load failed: The specified module could not be found

3. Opened a Visual Studio x64 command prompt.

4. Under Windows, a .pyd file is a .dll file in disguise, so we want to run dumpbin on this file.

5. cd MyLibrary\build\lib.win-amd64-3.7\Debug

6. dumpbin /dependents MyLibrary.cp37-win_amd64.pyd which prints this:

7. Searched for clang_rt.asan_dbg_dynamic-x86_64.dll, copied it into the same directory, problem solved.

8. Alternatively, could update the environment variable PATH to point to the directory with the missing .dll.

Please feel free to add your own case studies here! I've made it a community wiki answer.

Still anyone have this problem, use following code inside your form as below.

HandlerThread is better option to normal java Threads in Android .

1. Create a HandlerThread and start it
2. Create a Handler with Looper from HandlerThread :requestHandler
3. post a Runnable task on requestHandler

Communication with UI Thread from HandlerThread

1. Create a Handler with Looper for main thread : responseHandler and override handleMessage method
2. Inside Runnable task of other Thread ( HandlerThread in this case), call sendMessage on responseHandler
3. This sendMessage result invocation of handleMessage in responseHandler.
4. Get attributes from the Message and process it, update UI

Example: Update TextView with data received from a web service. Since web service should be invoked on non-UI thread, created HandlerThread for Network Operation. Once you get the content from the web service, send message to your main thread (UI Thread) handler and that Handler will handle the message and update UI.

Sample code:

HandlerThread handlerThread = new HandlerThread("NetworkOperation");
handlerThread.start();
Handler requestHandler = new Handler(handlerThread.getLooper());

final Handler responseHandler = new Handler(Looper.getMainLooper()) {
    @Override
    public void handleMessage(Message msg) {
        txtView.setText((String) msg.obj);
    }
};

Runnable myRunnable = new Runnable() {
    @Override
    public void run() {
        try {
            Log.d("Runnable", "Before IO call");
            URL page = new URL("http://www.your_web_site.com/fetchData.jsp");
            StringBuffer text = new StringBuffer();
            HttpURLConnection conn = (HttpURLConnection) page.openConnection();
            conn.connect();
            InputStreamReader in = new InputStreamReader((InputStream) conn.getContent());
            BufferedReader buff = new BufferedReader(in);
            String line;
            while ((line = buff.readLine()) != null) {
                text.append(line + "\n");
            }
            Log.d("Runnable", "After IO call:"+ text.toString());
            Message msg = new Message();
            msg.obj = text.toString();
            responseHandler.sendMessage(msg);


        } catch (Exception err) {
            err.printStackTrace();
        }
    }
};
requestHandler.post(myRunnable);

Adding a separate answer because it is radically different.

You could use rgba and set the alpha channel low (to get transparency) to make your drop shadow less noticeable.

Try something like this (play with the .5)

-webkit-box-shadow: 0px -4px 7px rbga(230, 230, 230, .5);
-moz-box-shadow: 0px -4px 7px rbga(230, 230, 230, .5);
box-shadow: 0px -4px 7px rbga(230, 230, 230, .5);

Hope this helps!

You could also, in another directory:

• git clone [your repository]
• Overwrite the .git directory in your original repository with the .git directory of the repository you just cloned right now.
• git add and git commit your original

Sepia and PDE have also own REPLs (for GNU Emacs).

Use awk(another great bash utility) instead of grep where you dont have the line buffered option! It will continuously stream your data from tail.

this is how you use grep

tail -f <file> | grep pattern

This is how you would use awk

tail -f <file> | awk '/pattern/{print $0}'

This might be interesting: From the documentation:

If you tried a merge which resulted in complex conflicts and want to start over, you can recover with git merge --abort.

But you could also do it the naive (but slow) way:

rm -Rf /tmp/repository
cp -r repository /tmp/
cd /tmp/repository
git merge ...
...if successful, do the real merge. :)

(Note: It won't work just cloning to /tmp, you'd need a copy, in order to be sure that uncommitted changes will not conflict).

There is always this of course:

(async () => {
    await ...

    // all of the script.... 

})();
// nothing else

This makes a quick function with async where you can use await. It saves you the need to make an async function which is great! //credits Silve2611

You may have to first update all the records that are null to the default value then use the alter table statement.

Update dbo.TableName

where Created is NULL

One important point is that Swift's == on strings might not be equivalent to Objective-C's -isEqualToString:. The peculiarity lies in differences in how strings are represented between Swift and Objective-C.

Just look on this example:

let composed = "Ö" // U+00D6 LATIN CAPITAL LETTER O WITH DIAERESIS
let decomposed = composed.decomposedStringWithCanonicalMapping // (U+004F LATIN CAPITAL LETTER O) + (U+0308 COMBINING DIAERESIS)

composed.utf16.count // 1
decomposed.utf16.count // 2

let composedNSString = composed as NSString
let decomposedNSString = decomposed as NSString

decomposed == composed // true, Strings are equal
decomposedNSString == composedNSString // false, NSStrings are not

NSString's are represented as a sequence of UTF–16 code units (roughly read as an array of UTF-16 (fixed-width) code units). Whereas Swift Strings are conceptually sequences of "Characters", where "Character" is something that abstracts extended grapheme cluster (read Character = any amount of Unicode code points, usually something that the user sees as a character and text input cursor jumps around).

The next thing to mention is Unicode. There is a lot to write about it, but here we are interested in something called "canonical equivalence". Using Unicode code points, visually the same "character" can be encoded in more than one way. For example, "Á" can be represented as a precomposed "Á" or as decomposed A + ?´ (that's why in example composed.utf16 and decomposed.utf16 had different lengths). A good thing to read on that is this great article.

-[NSString isEqualToString:], according to the documentation, compares NSStrings code unit by code unit, so:

[Á] != [A, ?´]

Swift's String == compares characters by canonical equivalence.

[ [Á] ] == [ [A, ?´] ]

In swift the above example will return true for Strings. That's why -[NSString isEqualToString:] is not equivalent to Swift's String ==. Equivalent pure Swift comparison could be done by comparing String's UTF-16 Views:

decomposed.utf16.elementsEqual(composed.utf16) // false, UTF-16 code units are not the same
decomposedNSString == composedNSString // false, UTF-16 code units are not the same
decomposedNSString.isEqual(to: composedNSString as String) // false, UTF-16 code units are not the same

Also, there is a difference between NSString == NSString and String == String in Swift. The NSString == will cause isEqual and UTF-16 code unit by code unit comparison, where as String == will use canonical equivalence:

decomposed == composed // true, Strings are equal
decomposed as NSString == composed as NSString // false, UTF-16 code units are not the same

And the whole example:

let composed = "Ö" // U+00D6 LATIN CAPITAL LETTER O WITH DIAERESIS
let decomposed = composed.decomposedStringWithCanonicalMapping // (U+004F LATIN CAPITAL LETTER O) + (U+0308 COMBINING DIAERESIS)

composed.utf16.count // 1
decomposed.utf16.count // 2

let composedNSString = composed as NSString
let decomposedNSString = decomposed as NSString

decomposed == composed // true, Strings are equal
decomposedNSString == composedNSString // false, NSStrings are not

decomposed.utf16.elementsEqual(composed.utf16) // false, UTF-16 code units are not the same
decomposedNSString == composedNSString // false, UTF-16 code units are not the same
decomposedNSString.isEqual(to: composedNSString as String) // false, UTF-16 code units are not the same

If the string was constructed in the same program, I would recommend using this:

String newline = System.getProperty("line.separator");
boolean hasNewline = word.contains(newline);

But if you are specced to use \n, this driver illustrates what to do:

class NewLineTest {
    public static void main(String[] args) {
        String hasNewline = "this has a newline\n.";
        String noNewline = "this doesn't";

        System.out.println(hasNewline.contains("\n"));
        System.out.println(hasNewline.contains("\\n"));
        System.out.println(noNewline.contains("\n"));
        System.out.println(noNewline.contains("\\n"));

    }

}

Resulted in

true
false
false
false

In reponse to your comment:

class NewLineTest {
    public static void main(String[] args) {
        String word = "test\n.";
        System.out.println(word.length());
        System.out.println(word);
        word = word.replace("\n","\n ");
        System.out.println(word.length());
        System.out.println(word);

    }

}

Results in

Try this for getting form input text value to JavaScript object...

var fieldPair = {};
$("#form :input").each(function() {
    if($(this).attr("name").length > 0) {
        fieldPair[$(this).attr("name")] = $(this).val();
    }
});

console.log(fieldPair);

template <typename charT>
static ichar<charT> *istring(const charT *s) { return (ichar<charT> *)s; }

int main()
{
    string s = "The STRING";
    wstring ws = L"The WSTRING";
    cout << istring(s)->find(istring("str")) << " " << istring(ws)->find(istring(L"wstr"))  << endl;
}

A little bit dirty, but short & fast.

Change your App theme to AppCombat..

Another useful way is with Concat.
More information in the official documentation.

List<string> first = new List<string> { "One", "Two", "Three" };
List<string> second = new List<string>() { "Four", "Five" };
first.Concat(second);

The output will be.

One
Two
Three
Four
Five

And there is another similar answer.

Better option is to use :

{{(100*score/questionCounter) || 0 | number:0}}

It sets default value of equation to 0 in the case when values are not initialized.

This is the perfect solution that worked for me without any 3rd party library.

Rendering a PDF Document in Android Activity/Fragment (Using PdfRenderer)

In macOS Catalina, and possibly some earlier versions, you can find out where the command line tools are installed using:

xcode-select -p a.k.a. xcode-select --print-path

Which will, if it is installed, respond with something like:

/Library/Developer/CommandLineTools

To find out which version you have installed there, you can use:

xcode-select -v a.k.a. xcode-select --version

Which will return something like:

xcode-select version 2370.

However, if you attempt to upgrade it to the latest version, assuming it is installed, using this:

xcode-select --install

You will receive in response:

xcode-select: error: command line tools are already installed, use "Software Update" to install updates

Which rather erroneously gives the impression you need to use Spotlight find something called 'Software Update'. In actual fact, you need to continue in the Terminal, and use this:

softwareupdate -i -a a.k.a. softwareupdate --install --all

Which tries to update everything it can and may well respond with:

Software Update Tool

Finding available software
No new software available.

To find out which versions of the different Apple SDKs are installed on your machine, use this:

xcodebuild -showsdks

You can text-align: center the body to center the container. Then text-align: left the container to get all the text, etc. to align left.

AWS / Heroku are both free for small hobby projects (to start with).

If you want to start an app right away, without much customization of the architecture, then choose Heroku.

If you want to focus on the architecture and to be able to use different web servers, then choose AWS. AWS is more time-consuming based on what service/product you choose, but can be worth it. AWS also comes with many plugin services and products.

Heroku

• Platform as a Service (PAAS)
• Good documentation
• Has built-in tools and architecture.
• Limited control over architecture while designing the app.
• Deployment is taken care of (automatic via GitHub or manual via git commands or CLI).
• Not time consuming.

AWS

• Infrastructure as a Service (IAAS)
• Versatile - has many products such as EC2, LAMBDA, EMR, etc.
• Can use a Dedicated instance for more control over the architecture, such as choosing the OS, software version, etc. There is more than one backend layer.
• Elastic Beanstalk is a feature similar to Heroku's PAAS.
• Can use the automated deployment, or roll your own.

set.seed(123)
llwork<-sample(1:length(mydata),round(0.75*length(mydata),digits=0)) 
wmydata<-mydata[llwork, ]
tmydata<-mydata[-llwork, ]

If start can't find what it's looking for, it does what you describe.

Since what you're doing should work, it's very likely you're leaving out some quotes (or putting extras in).

This usually happens when you are using a URI scheme that is not supported by the server in which the app is deployed. So, you might either want to check what all schemes your server supports and modify your request URI accordingly, or, you might want to add the support for that scheme in your server. The scope of your application should help you decide on this.

Heredoc syntax can be very useful:

// start the string with 3 <'s and then a word
// it doesn't have to be any particular string or length
// but it's common to make it in all caps.
echo <<< EOT
    in here is your string
    it has the same variable substitution rules
    as a double quoted string.
    when you end it, put the indicator word at the
    start of the line (no spaces before it)
    and put a semicolon after it
EOT;

i think this add new property in desired type without having to set a primitive value, like when property defined in class definition

var x = new ExpandoObject();
x.NewProp = default(string)

If you will change the ID then Toggle will not working same problem was with me i just change

<div class="collapse navbar-collapse" id="defaultNavbar1">
    <ul class="nav navbar-nav">

id="defaultNavbar1" then toggle is working

$num = array (0 => array ('id' => '20110209172713', 'Date' => '2011-02-09', 'Weight' => '200'),
          1 => array ('id' => '20110209172747', 'Date' => '2011-02-09', 'Weight' => '180'),
          2 => array ('id' => '20110209172827', 'Date' => '2011-02-09', 'Weight' => '175'),
          3 => array ('id' => '20110211204433', 'Date' => '2011-02-11', 'Weight' => '195'));

    foreach($num as $key => $val)   
    {                       
        $weight[] = $val['Weight'];
    }

     echo max($weight);
     echo min($weight);

If your app is in background, Firebase will not trigger onMessageReceived(). Why.....? I have no idea. In this situation, I do not see any point in implementing FirebaseMessagingService.

According to docs, if you want to process background message arrival, you have to send 'click_action' with your message. But it is not possible if you send message from Firebase console, only via Firebase API. It means you will have to build your own "console" in order to enable marketing people to use it. So, this makes Firebase console also quite useless!

There is really good, promising, idea behind this new tool, but executed badly.

I suppose we will have to wait for new versions and improvements/fixes!

return n from main is equivalent to exit(n).

The valid returned is the rest of your program. It's meaning is OS dependent. On unix, 0 means normal termination and non-zero indicates that so form of error forced your program to terminate without fulfilling its intended purpose.

It's unusual that your example returns 0 (normal termination) when it seems to have run out of memory.

public class User implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @Column(name = "USER_ID")
    Long userId;

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "sender", cascade = CascadeType.ALL)
    List<Notification> sender;

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "receiver", cascade = CascadeType.ALL)
    List<Notification> receiver;
}

public class Notification implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id

    @Column(name = "NOTIFICATION_ID")
    Long notificationId;

    @Column(name = "TEXT")
    String text;

    @Column(name = "ALERT_STATUS")

    AlertStatus alertStatus = AlertStatus.NEW;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "SENDER_ID")
    @JsonIgnore
    User sender;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "RECEIVER_ID")
    @JsonIgnore
    User receiver;
}

What I understood from the answer. mappedy="sender" value should be the same in the notification model. I will give you an example..

User model:

@OneToMany(fetch = FetchType.LAZY, mappedBy = "**sender**", cascade = CascadeType.ALL)
    List<Notification> sender;

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "**receiver**", cascade = CascadeType.ALL)
    List<Notification> receiver;

Notification model:

@OneToMany(fetch = FetchType.LAZY, mappedBy = "sender", cascade = CascadeType.ALL)
    List<Notification> **sender**;

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "receiver", cascade = CascadeType.ALL)
    List<Notification> **receiver**;

I gave bold font to user model and notification field. User model mappedBy="sender " should be equal to notification List sender; and mappedBy="receiver" should be equal to notification List receiver; If not, you will get error.

Yes, if bar is not None is more explicit, and thus better, assuming it is indeed what you want. That's not always the case, there are subtle differences: if not bar: will execute if bar is any kind of zero or empty container, or False. Many people do use not bar where they really do mean bar is not None.

You need to add 'checked' htmlAttribute in RadioButtonFor, if the radiobutton's value matches with Model.Gender value.

@{
        foreach (var item in Model.GenderList)
        {
            <div class="btn-group" role="group">
               <label class="btn btn-default">
                   @Html.RadioButtonFor(m => m.Gender, item.Key, (int)Model.Gender==item.Key ? new { @checked = "checked" } : null)
                   @item.Value
              </label>
            </div>
        }
    }

If you have used extern for functions before, exactly same philosophy is followed for templates. if not, going though extern for simple functions may help. Also, you may want to put the extern(s) in header file and include the header when you need it.

public class NumberFormatExceptionExample {
private static final String str = "123.234";
public static void main(String[] args){
float i = Float.valueOf(str); //Float.parseFloat(str);
System.out.println("Value parsed :"+i);
}
}

This should resolve the problem.

Can anyone suggest how should we handle this when the string comes in 35,000.00

In my case i was using some annotations from jetbrains library. I removed those annotations and dependencies and it worked fine.

So please check the libraries in android code and dependencies carefully.

I wanted to find a string between / and #, but # is sometimes optional. Here is the regex I use:

  (?<=\/)([^#]+)(?=#*)

It depends on what form of date / time you want:

• If you want the date / time as a single numeric value, then System.currentTimeMillis() gives you that, expressed as the number of milliseconds after the UNIX epoch (as a Java long). This value is a delta from a UTC time-point, and is independent of the local time-zone¹.

• If you want the date / time in a form that allows you to access the components (year, month, etc) numerically, you could use one of the following:

  • new Date() gives you a Date object initialized with the current date / time. The problem is that the Date API methods are mostly flawed ... and deprecated.

  • Calendar.getInstance() gives you a Calendar object initialized with the current date / time, using the default Locale and TimeZone. Other overloads allow you to use a specific Locale and/or TimeZone. Calendar works ... but the APIs are still cumbersome.

  • new org.joda.time.DateTime() gives you a Joda-time object initialized with the current date / time, using the default time zone and chronology. There are lots of other Joda alternatives ... too many to describe here. (But note that some people report that Joda time has performance issues.; e.g. https://stackoverflow.com/questions/6280829.)

  • in Java 8, calling java.time.LocalDateTime.now() and java.time.ZonedDateTime.now() will give you representations² for the current date / time.

Prior to Java 8, most people who know about these things recommended Joda-time as having (by far) the best Java APIs for doing things involving time point and duration calculations.

With Java 8 and later, the standard java.time package is recommended. Joda time is now considered "obsolete", and the Joda maintainers are recommending that people migrate.³.

^{1 - System.currentTimeMillis() gives the "system" time. While it is normal practice for the system clock to be set to (nominal) UTC, there will be a difference (a delta) between the local UTC clock and true UTC. The size of the delta depends on how well (and how often) the system's clock is synced with UTC.
2 - Note that LocalDateTime doesn't include a time zone. As the javadoc says: "It cannot represent an instant on the time-line without additional information such as an offset or time-zone."
3 - Note: your Java 8 code won't break if you don't migrate, but the Joda codebase may eventually stop getting bug fixes and other patches. As of 2020-02, an official "end of life" for Joda has not been announced, and the Joda APIs have not been marked as Deprecated.}

If your cron job is running on Mac OS X only, you may want to use launchd instead.

From Scheduling Timed Jobs (official Apple docs):

Note: Although it is still supported, cron is not a recommended solution. It has been deprecated in favor of launchd.

You can find additional information (such as the launchd Wikipedia page) with a simple web search.

There are a couple of topics that might provide you with an answer. You could also run some tests yourself. Doesn't see too hard to get some loops started and adding a timer to calculate the execution time ;-)

You can send an HTTP request to http://finance.yahoo.com requesting symbols, names, quotes, and all sorts of other data. Data is returned as a .CSV so you can request multiple symbols in one query.

So if you send:

http://finance.yahoo.com/d/quotes.csv?s=MSFT+F+ATT&f=sn

You'll get back something like:

"MSFT","Microsoft Corp"
"F","FORD MOTOR CO"
"ATT","AT&T"

Here is an article called Downloading Yahoo Data which includes the various tags used to request the data.

with a specific dir:

cd your_dir && curl -L https://download.calibre-ebook.com/3.19.0/calibre-3.19.0-x86_64.txz | tar zx

Specify the version of node The version of Node.js that will be used to run your application on Heroku, should also be defined in your package.json file. You should always specify a Node.js version that matches the runtime you’re developing and testing with. To find your version type node --version.

Your package.json file will look something like this:

"engines": { "node": "10.x" },

It should work

My solution:

//Object forEachDone

Object.defineProperty(Array.prototype, "forEachDone", {
    enumerable: false,
    value: function(task, cb){
        var counter = 0;
        this.forEach(function(item, index, array){
            task(item, index, array);
            if(array.length === ++counter){
                if(cb) cb();
            }
        });
    }
});


//Array forEachDone

Object.defineProperty(Object.prototype, "forEachDone", {
    enumerable: false,
    value: function(task, cb){
        var obj = this;
        var counter = 0;
        Object.keys(obj).forEach(function(key, index, array){
            task(obj[key], key, obj);
            if(array.length === ++counter){
                if(cb) cb();
            }
        });
    }
});

Example:

var arr = ['a', 'b', 'c'];

arr.forEachDone(function(item){
    console.log(item);
}, function(){
   console.log('done');
});

// out: a b c done

Try:

In the controller:

ViewBag.Accounts= new SelectList(db.Accounts, "AccountId", "AccountName");

In the View:

@Html.DropDownList("AccountId", (IEnumerable<SelectListItem>)ViewBag.Accounts, null, new { @class ="form-control" })

or you can replace the "null" with whatever you want display as default selector, i.e. "Select Account".

<div class="row" data-toggle="popover" data-trigger="hover" 
                 data-content="My popover content.My popover content.My popover content.My popover content.">
<div class="col-md-6">
    <label for="name">Name:</label>
    <input id="name" class="form-control" type="text" />
</div>
</div>

Basically i put the popover code in the row div, instead of the input div. Solved the problem.

You can also use the following syntax for the strongly typed version:

<% using (Html.BeginForm<SomeController>(x=> x.SomeAction(), 
          FormMethod.Post, 
          new { enctype = "multipart/form-data" })) 
   { %>

1. delete your project folder under C:\....\wildfly-9.0.1.Final\standalone\deployments\YOUR-PROJEKT-FOLDER
2. restart your wildfly-server

When I have a Store Procedure name, and do not know which database it belongs to, I use the following -

Use [master]
GO

DECLARE @dbname VARCHAR(50)   
DECLARE @statement NVARCHAR(max)

DECLARE db_cursor CURSOR 
LOCAL FAST_FORWARD
FOR  
--Status 48 (mirrored db)
SELECT name FROM MASTER.dbo.sysdatabases WHERE STATUS NOT LIKE 48 AND name NOT IN ('master','model','msdb','tempdb','distribution')  

OPEN db_cursor  
FETCH NEXT FROM db_cursor INTO @dbname  
WHILE @@FETCH_STATUS = 0  
BEGIN  

SELECT @statement = 'SELECT * FROM ['+@dbname+'].INFORMATION_SCHEMA.ROUTINES  WHERE [ROUTINE_NAME] LIKE ''%name_of_proc%'''+';'
print @statement

EXEC sp_executesql @statement

FETCH NEXT FROM db_cursor INTO @dbname  
END  
CLOSE db_cursor  
DEALLOCATE db_cursor

@Kwang-Chun Kang Thanks Kang a lot! I found the solution is working and very helpful, it really save my day. For me I am trying to create a React.js component that convert *.xlsx to json object when user upload the excel file to a html input tag. First I need to install XLSX package with:

npm install xlsx --save

Then in my component code, import with:

import XLSX from 'xlsx'

The component UI should look like this:

<input
  accept=".xlsx"
  type="file"
  onChange={this.fileReader}
/>

It calls a function fileReader(), which is exactly same as the solution provided. To learn more about fileReader API, I found this blog to be helpful: https://blog.teamtreehouse.com/reading-files-using-the-html5-filereader-api

SetTimeout is used to make your set of code to execute after a specified time period so for your requirements its better to use setInterval because that will call your function every time at a specified time interval.

Try:

return $this->sendRequest($uri);

Since PHP is not a pure Object-Orieneted language, it interprets sendRequest() as an attempt to invoke a globally defined function (just like nl2br() for example), but since your function is part of a class ('InstagramController'), you need to use $this to point the interpreter in the right direction.

Very simple example:

def loadById(self, id):
    if id in range(len(self.itemList)):
        self.load(self.itemList[id])

I can't think of a solution that does not use the range-len composition quickly.

But probably instead this should be done with try .. except to stay pythonic i guess..

In my case, I had the .eslintrc.json file inside the .vscode folder. Once I moved it out to the root folder, ESLint started working correctly.

I would go for Dan Tao's answer, but if you're not using .NET 4.0 you can do something like that:

public static string Repeat(this string str, int count)
{
    return Enumerable.Repeat(str, count)
                     .Aggregate(
                        new StringBuilder(str.Length * count),
                        (sb, s) => sb.Append(s))
                     .ToString();
}

It depends on the context. I think you're referring to the operating system's hostname (returned by hostname when you're logged in). This command is for internal names only, so to query for a machine's name requires different naming systems. There are multiple systems which use names to identify hosts including DNS, DHCP, LDAP (DN's), hostname, etc. and many systems use zeroconf to synchronize names between multiple naming systems. For this reason, results from hostname will sometimes match results from dig (see below) or other naming systems, but often times they will not match.

DNS is by far the most common and is used both on the internet (like google.com. A 216.58.218.142) and at home (mDNS/LLMNR), so here's how to perform a reverse DNS lookup: dig -x <address> (nslookup and host are simpler, provide less detail, and may even return different results; however, dig is not included in Windows).

Note that hostnames within a CDN will not resolve to the canonical domain name (e.g. "google.com"), but rather the hostname of the host IP you queried (e.g. "dfw25s08-in-f142.1e100.net"; interesting tidbit: 1e100 is 1 googol).

Also note that DNS hosts can have more than one name. This is common for hosts with more than one webserver (virtual hosting), although this is becoming less common thanks to the proliferation of virtualization technologies. These hosts have multiple PTR DNS records.

Finally, note that DNS host records can be overridden by the local machine via /etc/hosts. If you're not getting the hostname you expect, be sure you check this file.

DHCP hostnames are queried differently depending on which DHCP server software is used, because (as far as I know) the protocol does not define a method for querying; however, most servers provide some way of doing this (usually with a privileged account).

Note DHCP names are usually synchronized with DNS server(s), so it's common to see the same hostnames in a DHCP client least table and in the DNS server's A (or AAAA for IPv6) records. Again, this is usually done as part of zeroconf.

Also note that just because a DHCP lease exists for a client, doesn't mean it's still being used.

NetBIOS for TCP/IP (NBT) was used for decades to perform name resolution, but has since been replaced by LLMNR for name resolution (part of zeroconf on Windows). This legacy system can still be queried with the nbtstat (Windows) or nmblookup (Linux).

   /* Integer[] to List<Integer> */



        Integer[] intArr = { 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 };
        List<Integer> arrList = new ArrayList<>();
        arrList.addAll(Arrays.asList(intArr));
        System.out.println(arrList);


/* Integer[] to Collection<Integer> */


    Integer[] intArr = { 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 };
    Collection<Integer> c = Arrays.asList(intArr);

Usually, best is to see a character in his context.

Here is the full list of Unicode chars, and how your browser currently displays them. I am seeing this list evolving, browser versions after others.

This list is obtained by iteration in decimal of the html entities unicode table, it may take some seconds, but is very useful to me in many cases.

By hovering quickly a given char you will get the dec and hex and the shortcuts to generate it with a keyboard.

var i = 0
    do document.write("<a title='(Linux|Hex): [CTRL+SHIFT]+u"+(i).toString(16)+"\nHtml entity: &# "+i+";\n&#x"+(i).toString(16)+";\n(Win|Dec): [ALT]+"+i+"' onmouseover='this.focus()' onclick='this.href=\"//google.com/?q=\"+this.innerHTML' style='cursor:pointer' target='new'>"+"&#"+i+";</a>"),i++
    while (i<136690)
window.stop() 


//  From https://codepen.io/Nico_KraZhtest/pen/mWzXqy

The same snippet as a bookmarklet:

javascript:void%20!function(){var%20t=0;do{document.write(%22%3Ca%20title='(Linux|Hex):%20[CTRL+SHIFT]+u%22+t.toString(16)+%22\nHtml%20entity:%20%26%23%20%22+t+%22;\n%26%23x%22+t.toString(16)+%22;\n(Win|Dec):%20[ALT]+%22+t+%22'%20onmouseover='this.focus()'%20onclick='this.href=\%22https://google.com/%3Fq=\%22+this.innerHTML'%20style='cursor:pointer'%20target='new'%3E%26%23%22+t+%22;%3C/a%3E%22),t++}while(t%3C136690);window.stop()}();

To generate that list from php:

for ($x = 0; $x < 136690; $x++) {
  echo html_entity_decode('&#'.$x.';',ENT_NOQUOTES,'UTF-8');
}

To generate that list into the console, using php:

php -r 'for ($x = 0; $x < 136690; $x++) { echo html_entity_decode("&#".$x.";",ENT_NOQUOTES,"UTF-8");}'

Here is a plain text extract, of arrows, some are coming with unicode 10.0. http://unicode.org/versions/Unicode10.0.0/

Unicode 10.0 adds 8,518 characters, for a total of 136,690 characters.

???????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

Hey, did you notice the plain html <details> element has a drop down arrow? This is sometimes all what we need.

<details>
  <summary>Morning</summary>
  <p>Hello world!</p>
</details>
<details>
  <summary>Evening</summary>
  <p>How sweat?</p>

Your class doesn't have a __init__(), so by the time it's instantiated, the attribute atoms is not present. You'd have to do C.setdata('something') so C.atoms becomes available.

>>> C = Residues()
>>> C.atoms.append('thing')

Traceback (most recent call last):
  File "<pyshell#84>", line 1, in <module>
    B.atoms.append('thing')
AttributeError: Residues instance has no attribute 'atoms'

>>> C.setdata('something')
>>> C.atoms.append('thing')   # now it works
>>> 

Unlike in languages like Java, where you know at compile time what attributes/member variables an object will have, in Python you can dynamically add attributes at runtime. This also implies instances of the same class can have different attributes.

To ensure you'll always have (unless you mess with it down the line, then it's your own fault) an atoms list you could add a constructor:

def __init__(self):
    self.atoms = []

Clean function can be called from VBA this way:

Range("A1").Value = Application.WorksheetFunction.Clean(Range("A1"))

However as written here, the CLEAN function was designed to remove the first 32 non-printing characters in the 7 bit ASCII code (values 0 through 31) from text. In the Unicode character set, there are additional nonprinting characters (values 127, 129, 141, 143, 144, and 157). By itself, the CLEAN function does not remove these additional nonprinting characters.

Rick Rothstein have written code to handle even this situation here this way:

Function CleanTrim(ByVal S As String, Optional ConvertNonBreakingSpace As Boolean = True) As String
  Dim X As Long, CodesToClean As Variant
  CodesToClean = Array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, _
                       21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 127, 129, 141, 143, 144, 157)
  If ConvertNonBreakingSpace Then S = Replace(S, Chr(160), " ")
  For X = LBound(CodesToClean) To UBound(CodesToClean)
    If InStr(S, Chr(CodesToClean(X))) Then S = Replace(S, Chr(CodesToClean(X)), "")
  Next
  CleanTrim = WorksheetFunction.Trim(S)
End Function

Wow, there are some complex solutions here. So complex I decided to come up with something simpler but also quite powerful. Here it is;

function sortByPriority(data, priorities) {
  if (priorities.length == 0) {
    return data;
  }

  const nextPriority = priorities[0];
  const remainingPriorities = priorities.slice(1);

  const matched = data.filter(item => item.hasOwnProperty(nextPriority));
  const remainingData = data.filter(item => !item.hasOwnProperty(nextPriority));

  return sortByPriority(matched, remainingPriorities)
    .sort((a, b) => (a[nextPriority] > b[nextPriority]) ? 1 : -1)
    .concat(sortByPriority(remainingData, remainingPriorities));
}

And here is an example of how you use it.

const data = [
  { id: 1,                         mediumPriority: 'bbb', lowestPriority: 'ggg' },
  { id: 2, highestPriority: 'bbb', mediumPriority: 'ccc', lowestPriority: 'ggg' },
  { id: 3,                         mediumPriority: 'aaa', lowestPriority: 'ggg' },
];

const priorities = [
  'highestPriority',
  'mediumPriority',
  'lowestPriority'
];


const sorted = sortByPriority(data, priorities);

This will first sort by the precedence of the attributes, then by the value of the attributes.

This might not really answer the question, but just in case someone just need to quickly send a string value to a function that require a NSArray parameter.

NSArray *data = @[@"The String Value"];

if you need to send more than just 1 string value, you could also use

NSArray *data = @[@"The String Value", @"Second String", @"Third etc"];

then you can send it to the function like below

theFunction(data);

First off I would say use boost tokenizer.
Alternatively if your data is space separated then the string stream library is very useful.

But both the above have already been covered.
So as a third C-Like alternative I propose copying the std::string into a buffer for modification.

std::string   data("The data I want to tokenize");

// Create a buffer of the correct length:
std::vector<char>  buffer(data.size()+1);

// copy the string into the buffer
strcpy(&buffer[0],data.c_str());

// Tokenize
strtok(&buffer[0]," ");

As far as I know you can use all mentioned technologies separately or together. It's up to you. I think you look at the problem from the wrong angle. Material Design is just the way particular elements of the page are designed, behave and put together. Material Design provides great UI/UX, but it relies on the graphic layout (HTML/CSS) rather than JS (events, interactions).

On the other hand, AngularJS and Bootstrap are front-end frameworks that can speed up your development by saving you from writing tons of code. For example, you can build web app utilizing AngularJS, but without Material Design. Or You can build simple HTML5 web page with Material Design without AngularJS or Bootstrap. Finally you can build web app that uses AngularJS with Bootstrap and with Material Design. This is the best scenario. All technologies support each other.

1. Bootstrap = responsive page
2. AngularJS = MVC
3. Material Design = great UI/UX

You can check awesome material design components for AngularJS:

AppendDataBoundItems="true" needs to be set.

add this to your form:

<form  id="regform" action="insert.php" method="post">

add this to your function:

<script>
    function myFunction() {
        var pass1 = document.getElementById("pass1").value;
        var pass2 = document.getElementById("pass2").value;
        if (pass1 != pass2) {
            //alert("Passwords Do not match");
            document.getElementById("pass1").style.borderColor = "#E34234";
            document.getElementById("pass2").style.borderColor = "#E34234";
        }
        else {
            alert("Passwords Match!!!");
            document.getElementById("regForm").submit();
        }
    }
</script>

From the man git-stash page:

The modifications stashed away by this command can be listed with git stash list, inspected with git stash show

show [<stash>]
       Show the changes recorded in the stash as a diff between the stashed state and
       its original parent. When no <stash> is given, shows the latest one. By default,
       the command shows the diffstat, but it will accept any format known to git diff
       (e.g., git stash show -p stash@{1} to view the second most recent stash in patch
       form).

To list the stashed modifications

git stash list

To show files changed in the last stash

git stash show

So, to view the content of the most recent stash, run

git stash show -p

To view the content of an arbitrary stash, run something like

git stash show -p stash@{1}

You can put expressions inside braces. Notice in the compiled JavaScript why a for loop would never be possible inside JSX syntax; JSX amounts to function calls and sugared function arguments. Only expressions are allowed.

(Also: Remember to add key attributes to components rendered inside loops.)

JSX + ES2015:

render() {
  return (
    <table className="MyClassName">
      <thead>
        <tr>
          {this.props.titles.map(title =>
            <th key={title}>{title}</th>
          )}
        </tr>
      </thead>
      <tbody>
        {this.props.rows.map((row, i) =>
          <tr key={i}>
            {row.map((col, j) =>
              <td key={j}>{col}</td>
            )}
          </tr>
        )}
      </tbody>
    </table>
  );
} 

JavaScript:

render: function() {
  return (
    React.DOM.table({className: "MyClassName"}, 
      React.DOM.thead(null, 
        React.DOM.tr(null, 
          this.props.titles.map(function(title) {
            return React.DOM.th({key: title}, title);
          })
        )
      ), 
      React.DOM.tbody(null, 
        this.props.rows.map(function(row, i) {
          return (
            React.DOM.tr({key: i}, 
              row.map(function(col, j) {
                return React.DOM.td({key: j}, col);
              })
            )
          );
        })
      )
    )
  );
} 

I don't know why you want to do that, but try:

SELECT *
INTO NewTable
FROM OldTable
WHERE 1 = 2

It should work.

One of the ways that you can run your spring-boot application from command line is as follows :

1) First go to your project directory in command line [where is your project located ?]

2) Then in the next step you have to create jar file for that, this can be done as

mvnw package [for WINDOWS OS ] or ./mvnw package [for MAC OS] , this will create jar file for our application.

3) jar file is created in the target sub-directory

4)Now go to target sub directory as jar was created inside of it , i.e cd target

5) Now run the jar file in there. Use command java -jar name.jar [ name is the name of your created jar file.]

and there you go , you are done . Now you can run project in browser,

 http://localhost:port_number

If you have no FIRST/FIRST conflicts and no FIRST/FOLLOW conflicts, your grammar is LL(1).

An example of a FIRST/FIRST conflict:

S -> Xb | Yc
X -> a 
Y -> a 

By seeing only the first input symbol a, you cannot know whether to apply the production S -> Xb or S -> Yc, because a is in the FIRST set of both X and Y.

An example of a FIRST/FOLLOW conflict:

S -> AB 
A -> fe | epsilon 
B -> fg 

By seeing only the first input symbol f, you cannot decide whether to apply the production A -> fe or A -> epsilon, because f is in both the FIRST set of A and the FOLLOW set of A (A can be parsed as epsilon and B as f).

Notice that if you have no epsilon-productions you cannot have a FIRST/FOLLOW conflict.

JSON in any HTML tag except <script> tag would be a mere text. Thus it's like you add a story to your HTML page.

However, about formatting, that's another matter. I guess you should change the title of your question.

Take a look at this question. Also see this page.

ArrayList myList = new ArrayList(10);

//  myList.add(3, "DDD");
//  myList.add(9, "III");
    myList.add(0, "AAA");
    myList.add(1, "BBB");

    for(String item:myList){
        System.out.println("inside list : "+item);
    }

/*Declare the initial capasity of arraylist is nothing but saving shifting time in internally; when we add the element internally it check the capasity to increase the capasity, you could add the element at 0 index initially then 1 and so on. */

Try wordlists[len(words)]. () is a function call. When you do wordlists(..), python thinks that you are calling a function called wordlists which turns out to be a list. Hence the error.

Well, you're on the right path, Benno!

There are some tips regarding VBA programming that might help you out.

1. Use always explicit references to the sheet you want to interact with. Otherwise, Excel may 'assume' your code applies to the active sheet and eventually you'll see it screws your spreadsheet up.

2. As lionz mentioned, get in touch with the native methods Excel offers. You might use them on most of your tricks.

3. Explicitly declare your variables... they'll show the list of methods each object offers in VBA. It might save your time digging on the internet.

Now, let's have a draft code...

Remember this code must be within the Excel Sheet object, as explained by lionz. It only applies to Sheet 2, is up to you to adapt it to both Sheet 2 and Sheet 3 in the way you prefer.

Hope it helps!

Private Sub Worksheet_Change(ByVal Target As Range)

    Dim oSheet As Excel.Worksheet

    'We only want to do something if the changed cell is B6, right?
    If Target.Address = "$B$6" Then

        'Checks if it's a number...
        If IsNumeric(Target.Value) Then

            'Let's avoid values out of your bonds, correct?
            If Target.Value > 0 And Target.Value < 51 Then

                'Let's assign the worksheet we'll show / hide rows to one variable and then
                '   use only the reference to the variable itself instead of the sheet name.
                '   It's safer.

                'You can alternatively replace 'sheet 2' by 2 (without quotes) which will represent
                '   the sheet index within the workbook
                Set oSheet = ActiveWorkbook.Sheets("Sheet 2")

                'We'll unhide before hide, to ensure we hide the correct ones
                oSheet.Range("A7:A56").EntireRow.Hidden = False

                oSheet.Range("A" & Target.Value + 7 & ":A56").EntireRow.Hidden = True

            End If

        End If

    End If

You could do this:

SELECT * FROM table WHERE cast(YOUR_INTEGER_VALUE as varchar) = 'string of numbers'

Go to your web.config/App.config to verify which .net runtime you are using

  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
  </startup>

Here is the solution:

1. .NET 4.6 and above. You don’t need to do any additional work to support TLS 1.2, it’s supported by default.

2. .NET 4.5. TLS 1.2 is supported, but it’s not a default protocol. You need to opt-in to use it. The following code will make TLS 1.2 default, make sure to execute it before making a connection to secured resource:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12

3. .NET 4.0. TLS 1.2 is not supported, but if you have .NET 4.5 (or above) installed on the system then you still can opt in for TLS 1.2 even if your application framework doesn’t support it. The only problem is that SecurityProtocolType in .NET 4.0 doesn’t have an entry for TLS1.2, so we’d have to use a numerical representation of this enum value:

ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;

4. .NET 3.5 or below. TLS 1.2 is not supported (*) and there is no workaround. Upgrade your application to more recent version of the framework.

Try this

Console.WriteLine("\a")

The approach with istringstream can be improved in order to check that no other characters have been inserted after the expected argument:

#include <sstream>

int main(int argc, char *argv[])
{
    if (argc >= 2)
    {
        std::istringstream iss( argv[1] );
        int val;

        if ((iss >> val) && iss.eof()) // Check eofbit
        {
            // Conversion successful
        }
    }

    return 0;
}

1. Create nuget.config in same directory where your solution file is, with following content:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <config>
    <add key="repositoryPath" value="packages" />
  </config>
</configuration>

'packages' will be the folder where all packages will be restored.

2. Close Visual studio solution and open it again.

Delete _MigrationHistory table in (yourdatabseName > Tables > System Tables) if you already have in your database and then run below command in package manager console

PM> update-database

The worst thing of using just

console.log({'some stuff': 2} + '\n' + 'something')

is that all stuff are converted to the string and if you need object to show you may see next:

[object Object]

Thus my variant is the next code:

console.log({'some stuff': 2},'\n' + 'something');

Before installation use the Control Panel Region and Language Preferences tool to change everything (Format, Keyboard default input, language for non Unicode programs) to English. Revert to the original selections after the installation.

Dont use spaces:

SET @var="GREG"
::instead of SET @var = "GREG"
ECHO %@var%
PAUSE

The error message says it all. At runtime, the type is gone, there is no way to check for it.

You could catch it by making a factory for your object like this:

 public static <T> MyObject<T> createMyObject(Class<T> type) {
    return new MyObject<T>(type);
 }

And then in the object's constructor store that type, so variable so that your method could look like this:

        if (arg0 != null && !(this.type.isAssignableFrom(arg0.getClass()))
        {
            return -1;
        }

Your code is fine. What you are seeing is a linker issue.

If you put your code in a single file like this:

#include <iostream>
#include <string>

using namespace std;

string trim(const string& str)
{
    size_t first = str.find_first_not_of(' ');
    if (string::npos == first)
    {
        return str;
    }
    size_t last = str.find_last_not_of(' ');
    return str.substr(first, (last - first + 1));
}

int main() {
    string s = "abc ";
    cout << trim(s);

}

then do g++ test.cc and run a.out, you will see it works.

You should check if the file that contains the trim function is included in the link stage of your compilation process.

try this

//WITH FIRST COLUMN
arr = arr.sort(function(a,b) {
    return a[0] - b[0];
});


//WITH SECOND COLUMN
arr = arr.sort(function(a,b) {
    return a[1] - b[1];
});

Note: Original answer used a greater than (>) instead of minus (-) which is what the comments are referring to as incorrect.

var myregexp = /\[(\d+)\]\[(\d+)\]/;
var match = myregexp.exec(text);
if (match != null) {
    var productId = match[1];
    var shopId = match[2];
} else {
    // no match
}

std::atan2 allows calculating the arctangent of all four quadrants. std::atan only allows calculating from quadrants 1 and 4.

Given just the pointer, you can't. You'll have to keep hold of the length you passed to new[] or, better, use std::vector to both keep track of the length, and release the memory when you've finished with it.

Here is a simple example of how to use imageEdgeInsets This will make a 30x30 button with a hittable area 10 pixels bigger all the way around (50x50)

    var expandHittableAreaAmt : CGFloat = 10
    var buttonWidth : CGFloat = 30
    var button = UIButton.buttonWithType(UIButtonType.Custom) as UIButton
    button.frame = CGRectMake(0, 0, buttonWidth+expandHittableAreaAmt, buttonWidth+expandHittableAreaAmt)
    button.imageEdgeInsets = UIEdgeInsetsMake(expandHittableAreaAmt, expandHittableAreaAmt, expandHittableAreaAmt, expandHittableAreaAmt)
    button.setImage(UIImage(named: "buttonImage"), forState: .Normal)
    button.addTarget(self, action: "didTouchButton:", forControlEvents:.TouchUpInside)

Add this function at the beginning of your script :

import sys, os 
    def resource_path(relative_path):
        if hasattr(sys, '_MEIPASS'):
            return os.path.join(sys._MEIPASS, relative_path)
        return os.path.join(os.path.abspath("."), relative_path)

Refer to your data files by calling the function resource_path(), like this:

resource_path('myimage.gif')

Then use this command:

pyinstaller --onefile --windowed --add-data todo.ico;. script.py

if you want only to update model if exist (without create it):

Model.objects.filter(id = 223).update(field1 = 2)

mysql query:

UPDATE `model` SET `field1` = 2 WHERE `model`.`id` = 223

sorted(dict.keys())[-1]

Otherwise, the keys is just an unordered list, and the "last one" is meaningless, and even can be different on various python versions.

Maybe you want to look into OrderedDict.

This may not specifically answer your long 3 part question but this thread is old and I found this while searching today. Here is one shorter way to: "Wait until a process has finished." If you know the name of the process such as "EXCEL.EXE"

strProcess = "EXCEL.EXE"    
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
Set colProcesses = objWMIService.ExecQuery ("Select * from Win32_Process Where Name = '"& strProcess &"'")
Do While colProcesses.Count > 0
    Set colProcesses = objWMIService.ExecQuery ("Select * from Win32_Process Where Name = '"& strProcess &"'")
    Wscript.Sleep(1000) 'Sleep 1 second
   'msgbox colProcesses.count 'optional to show the loop works

Have you tried HttpServerUtility.UrlDecode or HttpUtility.UrlDecode?

Your third assertion is incorrect.

It's perfectly legal for two unequal objects to have the same hash code. It's used by HashMap as a "first pass filter" so that the map can quickly find possible entries with the specified key. The keys with the same hash code are then tested for equality with the specified key.

You wouldn't want a requirement that two unequal objects couldn't have the same hash code, as otherwise that would limit you to 2³² possible objects. (It would also mean that different types couldn't even use an object's fields to generate hash codes, as other classes could generate the same hash.)

Here is a small example for those who want to peruse quickly

 object ApplyExample01 extends App {


  class Greeter1(var message: String) {
    println("A greeter-1 is being instantiated with message " + message)


  }

  class Greeter2 {


    def apply(message: String) = {
      println("A greeter-2 is being instantiated with message " + message)
    }
  }

  val g1: Greeter1 = new Greeter1("hello")
  val g2: Greeter2 = new Greeter2()

  g2("world")


} 

output

A greeter-1 is being instantiated with message hello

A greeter-2 is being instantiated with message world

There is a "3 of 9" control on CodeProject: Barcode .NET Control

Answer to use "/I" is working but with little trick - in target you must end with character \ to tell xcopy that target is directory and not file!

Example:

xcopy "$(TargetDir)$(TargetName).dll" "$(SolutionDir)_DropFolder" /F /R /Y /I

does not work and return code 2, but this one:

xcopy "$(TargetDir)$(TargetName).dll" "$(SolutionDir)_DropFolder\" /F /R /Y /I

Command line arguments used in my sample:

/F - Displays full source & target file names

/R - This will overwrite read-only files

/Y - Suppresses prompting to overwrite an existing file(s)

/I - Assumes that destination is directory (but must ends with \)

[EDIT: March 2016: thanks for the votes! Though really, this is not the best answer, I think the solutions based on withColumn, withColumnRenamed and cast put forward by msemelman, Martin Senne and others are simpler and cleaner].

I think your approach is ok, recall that a Spark DataFrame is an (immutable) RDD of Rows, so we're never really replacing a column, just creating new DataFrame each time with a new schema.

Assuming you have an original df with the following schema:

scala> df.printSchema
root
 |-- Year: string (nullable = true)
 |-- Month: string (nullable = true)
 |-- DayofMonth: string (nullable = true)
 |-- DayOfWeek: string (nullable = true)
 |-- DepDelay: string (nullable = true)
 |-- Distance: string (nullable = true)
 |-- CRSDepTime: string (nullable = true)

And some UDF's defined on one or several columns:

import org.apache.spark.sql.functions._

val toInt    = udf[Int, String]( _.toInt)
val toDouble = udf[Double, String]( _.toDouble)
val toHour   = udf((t: String) => "%04d".format(t.toInt).take(2).toInt ) 
val days_since_nearest_holidays = udf( 
  (year:String, month:String, dayOfMonth:String) => year.toInt + 27 + month.toInt-12
 )

Changing column types or even building a new DataFrame from another can be written like this:

val featureDf = df
.withColumn("departureDelay", toDouble(df("DepDelay")))
.withColumn("departureHour",  toHour(df("CRSDepTime")))
.withColumn("dayOfWeek",      toInt(df("DayOfWeek")))              
.withColumn("dayOfMonth",     toInt(df("DayofMonth")))              
.withColumn("month",          toInt(df("Month")))              
.withColumn("distance",       toDouble(df("Distance")))              
.withColumn("nearestHoliday", days_since_nearest_holidays(
              df("Year"), df("Month"), df("DayofMonth"))
            )              
.select("departureDelay", "departureHour", "dayOfWeek", "dayOfMonth", 
        "month", "distance", "nearestHoliday")            

which yields:

scala> df.printSchema
root
 |-- departureDelay: double (nullable = true)
 |-- departureHour: integer (nullable = true)
 |-- dayOfWeek: integer (nullable = true)
 |-- dayOfMonth: integer (nullable = true)
 |-- month: integer (nullable = true)
 |-- distance: double (nullable = true)
 |-- nearestHoliday: integer (nullable = true)

This is pretty close to your own solution. Simply, keeping the type changes and other transformations as separate udf vals make the code more readable and re-usable.

You could use wmic command:

wmic logicaldisk where drivetype=2 get <DeviceID, VolumeName, Description, ...>

Drivetype 2 indicates that its a removable disk.

It depends a bit on what you want:

A) If you want to specify which libraries to link to, you can use find_library to find libs and then use link_directories and target_link_libraries to.

Of course, it is often worth the effort to write a good find_package script, which nicely adds "imported" libraries with add_library( YourLib IMPORTED ) with correct locations, and platform/build specific pre- and suffixes. You can then simply refer to 'YourLib' and use target_link_libraries.

B) If you wish to specify particular linker-flags, e.g. '-mthreads' or '-Wl,--export-all-symbols' with MinGW-GCC, you can use CMAKE_EXE_LINKER_FLAGS. There are also two similar but undocumented flags for modules, shared or static libraries:

CMAKE_MODULE_LINKER_FLAGS
CMAKE_SHARED_LINKER_FLAGS
CMAKE_STATIC_LINKER_FLAGS

If you want new columns showing year and month separately you can do this:

df['year'] = pd.DatetimeIndex(df['ArrivalDate']).year
df['month'] = pd.DatetimeIndex(df['ArrivalDate']).month

or...

df['year'] = df['ArrivalDate'].dt.year
df['month'] = df['ArrivalDate'].dt.month

Then you can combine them or work with them just as they are.

In PyQt there are a lot of options for getting asynchronous behavior. For things that need event processing (ie. QtNetwork, etc) you should use the QThread example I provided in my other answer on this thread. But for the vast majority of your threading needs, I think this solution is far superior than the other methods.

The advantage of this is that the QThreadPool schedules your QRunnable instances as tasks. This is similar to the task pattern used in Intel's TBB. It's not quite as elegant as I like but it does pull off excellent asynchronous behavior.

This allows you to utilize most of the threading power of Qt in Python via QRunnable and still take advantage of signals and slots. I use this same code in several applications, some that make hundreds of asynchronous REST calls, some that open files or list directories, and the best part is using this method, Qt task balances the system resources for me.

    :param slot updatecb: the callback when data is receieved cb(uid, data)
    :param slot errorcb: the callback when there is an error cb(uid, errmsg)

    The uid option is useful when the calling code makes multiple async calls
    and the callbacks need some context about what was sent to the async method.
    For example, if you use this method to thread a long running database call
    and the user decides they want to cancel it and start a different one, the
    first one may complete before you have a chance to cancel the task.  In that
    case, the "readycb" will be called with the cancelled task's data.  The uid

    layout = QtGui.QVBoxLayout(dialog)
    button = QtGui.QPushButton("Generate", dialog)
    progress = QtGui.QProgressBar(dialog)
    progress.setRange(0, 0)
    layout.addWidget(button)
    layout.addWidget(progress)

    app.exec_()
    app.deleteLater() # avoids some QThread messages in the shell on exit
    # cancel all running tasks avoid QThread/QTimer error messages
    # on exit
    Request.shutdown()

When exiting the application you'll want to make sure you cancel all of the tasks or the application will hang until every scheduled task has completed

You can also try this:

<div ng-init="myVar = 'www.thesoftdesign'">
        <h1>Tutorials</h1>
        <p>Go to <a ng-href="{{myVar}}">{{myVar}}</a> to learn!</p>
</div>

The better pattern is to create a standalone BroadcastReceiver. This insures that your app can respond to the broadcast, whether or not the Service is running. In fact, using this pattern may remove the need for a constant-running Service altogether.

Register the BroadcastReceiver in your Manifest, and create a separate class/file for it.

Eg:

<receiver android:name=".FooReceiver" >
    <intent-filter >
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

When the receiver runs, you simply pass an Intent (Bundle) to the Service, and respond to it in onStartCommand().

Eg:

public class FooReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // do your work quickly!
        // then call context.startService();
    }   
}

function replaceAll(str, find, replace) {
  var i = str.indexOf(find);
  if (i > -1){
    str = str.replace(find, replace); 
    i = i + replace.length;
    var st2 = str.substring(i);
    if(st2.indexOf(find) > -1){
      str = str.substring(0,i) + replaceAll(st2, find, replace);
    }       
  }
  return str;
}

My problem was I could not work with localhost I needed to set it to localhost's IP address

network.bind_host: 127.0.0.1

select DocumentFormat.OpenXml under references , view it's properties, and set the Copy Local option to True so that it copies it to the output folder. That worked for me.

<graphics.h> is not a standard header. Most commonly it refers to the header for Borland's BGI API for DOS and is antiquated at best.

However it is nicely simple; there is a Win32 implementation of the BGI interface called WinBGIm. It is implemented using Win32 GDI calls - the lowest level Windows graphics interface. As it is provided as source code, it is perhaps a simple way of understanding how GDI works.

WinBGIm however is by no means cross-platform. If all you want are simple graphics primitives, most of the higher level GUI libraries such as wxWidgets and Qt support that too. There are simpler libraries suggested in the possible duplicate answers mentioned in the comments.

If you are trying to send mail from your local enviroment eg. XAMPP or WAMP, this error will occur everytime, go ahead and try the same code on your web hosting or whatever you are using for production.

Also, 2 step authentication from google may be the issue.

If you do Code-First and already have a Database:

public override void Up()
{
    AlterColumn("dbo.MyTable","Id", c =>  c.Guid(nullable: false, identity: true, defaultValueSql: "newsequentialid()"));
}

Thank you all for responding. After a further investigation I got to the right answer. As mentioned by Skip Head, the TimeStamped I was getting from my application was being adjusted to the user's TimeZone. So if the User entered 6:12 PM (EST) I would get 2:12 PM (GMT). What I needed was a way to undo the conversion so that the time entered by the user is the time I sent to the WebServer request. Here's how I accomplished this:

// Get TimeZone of user
TimeZone currentTimeZone = sc_.getTimeZone();
Calendar currentDt = new GregorianCalendar(currentTimeZone, EN_US_LOCALE);
// Get the Offset from GMT taking DST into account
int gmtOffset = currentTimeZone.getOffset(
    currentDt.get(Calendar.ERA), 
    currentDt.get(Calendar.YEAR), 
    currentDt.get(Calendar.MONTH), 
    currentDt.get(Calendar.DAY_OF_MONTH), 
    currentDt.get(Calendar.DAY_OF_WEEK), 
    currentDt.get(Calendar.MILLISECOND));
// convert to hours
gmtOffset = gmtOffset / (60*60*1000);
System.out.println("Current User's TimeZone: " + currentTimeZone.getID());
System.out.println("Current Offset from GMT (in hrs):" + gmtOffset);
// Get TS from User Input
Timestamp issuedDate = (Timestamp) getACPValue(inputs_, "issuedDate");
System.out.println("TS from ACP: " + issuedDate);
// Set TS into Calendar
Calendar issueDate = convertTimestampToJavaCalendar(issuedDate);
// Adjust for GMT (note the offset negation)
issueDate.add(Calendar.HOUR_OF_DAY, -gmtOffset);
System.out.println("Calendar Date converted from TS using GMT and US_EN Locale: "
    + DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.SHORT)
    .format(issueDate.getTime()));

The code's output is: (User entered 5/1/2008 6:12PM (EST)

Current User's TimeZone: EST
Current Offset from GMT (in hrs):-4 (Normally -5, except is DST adjusted)
TS from ACP: 2008-05-01 14:12:00.0
Calendar Date converted from TS using GMT and US_EN Locale: 5/1/08 6:12 PM (GMT)

Apps can’t be deleted if they are part of a Game Center group, in an app bundle, or currently displayed on a store. You’ll want to remove the app from sale or from the group if you want to delete it.

Little bit difference from Hari:

Right click on project ---> Properties ---> Java Build Path ---> Add Library... ---> Server Runtime ---> Apache Tomcat ----> Finish.

The following will result in a comma separated list. Be sure to include a using statement for System.Linq

List<string> ls = new List<string>();
ls.Add("one");
ls.Add("two");
string type = ls.Aggregate((x,y) => x + "," + y);

will yield one,two

if you need a space after the comma, simply change the last line to string type = ls.Aggregate((x,y) => x + ", " + y);

I have faced same issue, add jsonbackref and jsonmanagedref and please make sure @override equals and hashCode methods , this definitely fix this issue.

Because one moderator deleted my detailed image-supported answer on this question, just because I copied and pasted from another question, I am forced to put a less detailed answer and I will link the original answer if you want a more visual way to see the solution.

For Visual Studio 2019 and Visual Studio 2017 Users
For People who are missing this old feature in VS2019 (or maybe VS2017) from the old versions of Visual Studio

This feature still available, but it is NOT available by default, you have to install it separately.

1. Open VS 2019 go to Tools -> Get Tools and Features
2. Select the Individual components tab and search for Class Designer
3. Select this Component and Install it, After finish installing this component (you may need to restart visual studio)
4. Right-click on the project and select Add -> Add New Item
5. Search for 'class' word and NOW you can see Class Diagram component

see this answer also to see an image associated

(whish that the moderator realized this is the same question and instead of deleting my answer, he could mark one of the questions as duplicated to the other)

Update to create a class-diagram for the whole project
I received a downvote because I did not mention how to generate a diagram for the whole project, here is how to do it (after applying the previous steps)

1. Add class diagram to the project
2. if the option Preview Selected Items is enabled in the solution explorer, disabled it temporarily, you can re-enable it later

3. open the class diagram that you created in step 2 (by double-clicking on it)
4. drag-and-drop the project from the solution explorer to the class diagram

you could be shocked by the results to the point that you can change your mind and remove your downvote (please do NOT upvote, it is enough to remove your downvote)

Here's one of my favorite places to use the ** syntax as in Dave Webb's final example:

mynum = 1000
mystr = 'Hello World!'
print("{mystr} New-style formatting is {mynum}x more fun!".format(**locals()))

I'm not sure if it's terribly fast when compared to just using the names themselves, but it's a lot easier to type!

You can use following code for open actionSheet in Swift

        let alert = UIAlertController(title: enter your title, message: "Enter your messgage. ", preferredStyle: UIAlertControllerStyle.Alert)

        alert.addTextFieldWithConfigurationHandler(configurationTextField)

        alert.addAction(UIAlertAction(title: "Close", style: UIAlertActionStyle.Cancel, handler:{ (UIAlertAction)in
            print("User click Cancel button")
        }))

        alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler:{ (UIAlertAction)in
            print("User click Ok button")


        }))
        self.presentViewController(alert, animated: true, completion: {
            print("completion block")
        })

I faced the same problem but the issue was very silly, By mistake I have given wrong relationship I have given relationship between 2 Ids.

I got this issue on a Web API project. Finally figured out that it was in my "///" method comments. I have these comments set to auto-generate documentation for the API methods. Something in my comments made it go crazy. I deleted all the carriage returns, special characters, etc. Not really sure which thing it didn't like, but it worked.

you can also use this command :

wget --mirror -pc --convert-links -P ./your-local-dir/ http://www.your-website.com

so that you get the exact mirror of the website you want to download

Mongo 3.*.* - OSX - 2017

To run a single server database:

$ mkdir /data/db
$ ./mongod

Go to new Terminal

$ # The mongo javascript shell connects to localhost and test database 
$ # by default -Run the following command in new terminal
$ ./mongo

I didn't know what I was doing when I started changing the Apache configuration. I picked up bits and pieces thought it was working until I ran into the same problem you encountered, specifically Chrome having this error.

What I did was comment out all the site-specific directives that are used to configure SSL verification, confirmed that Chrome let me in, reviewed the documentation before directive before re-enabling one, and restarted Apache. By carefully going through these you ought to be able to figure out which one(s) are causing your problem.

In my case, I went from this:

SSLVerifyClient optional
SSLVerifyDepth 1
SSLOptions +StdEnvVars +StrictRequire
SSLRequireSSL On

to this

<Location /sessions>
  SSLRequireSSL
  SSLVerifyClient require
</Location>

As you can see I had a fair number of changes to get there.

If you're already using the tidyverse, there are a few solution depending on the exact situation.

Basic if you know it's all numbers and doesn't have NAs

library(dplyr)

# solution
dataset %>% mutate_if(is.character,as.numeric)

Test cases

df <- data.frame(
  x1 = c('1','2','3'),
  x2 = c('4','5','6'),
  x3 = c('1','a','x'), # vector with alpha characters
  x4 = c('1',NA,'6'), # numeric and NA
  x5 = c('1',NA,'x'), # alpha and NA
  stringsAsFactors = F)

# display starting structure
df %>% str()

Convert all character vectors to numeric (could fail if not numeric)

df %>%
  select(-x3) %>% # this removes the alpha column if all your character columns need converted to numeric
  mutate_if(is.character,as.numeric) %>%
  str()

Check if each column can be converted. This can be an anonymous function. It returns FALSE if there is a non-numeric or non-NA character somewhere. It also checks if it's a character vector to ignore factors. na.omit removes original NAs before creating "bad" NAs.

is_all_numeric <- function(x) {
  !any(is.na(suppressWarnings(as.numeric(na.omit(x))))) & is.character(x)
}
df %>% 
  mutate_if(is_all_numeric,as.numeric) %>%
  str()

If you want to convert specific named columns, then mutate_at is better.

df %>% mutate_at('x1', as.numeric) %>% str()

#include "stdio.h"

void print_ip(int ip) {
   unsigned char bytes[4];
   int i;
   for(i=0; i<4; i++) {
      bytes[i] = (ip >> i*8) & 0xFF;
   }
   printf("%d.%d.%d.%d\n", bytes[3], bytes[2], bytes[1], bytes[0]);
}

int main() {
   int ip = 0xDEADBEEF;
   print_ip(ip);   
}

At my previous job we struggled with getting our rich UI app to paint instantly and smoothly. We were using standard .Net controls, custom controls and devexpress controls.

After a lot of googling and reflector usage I came across the WM_SETREDRAW win32 message. This really stops controls drawing whilst you update them and can be applied, IIRC to the parent/containing panel.

This is a very very simple class demonstrating how to use this message:

class DrawingControl
{
    [DllImport("user32.dll")]
    public static extern int SendMessage(IntPtr hWnd, Int32 wMsg, bool wParam, Int32 lParam);

    private const int WM_SETREDRAW = 11; 

    public static void SuspendDrawing( Control parent )
    {
        SendMessage(parent.Handle, WM_SETREDRAW, false, 0);
    }

    public static void ResumeDrawing( Control parent )
    {
        SendMessage(parent.Handle, WM_SETREDRAW, true, 0);
        parent.Refresh();
    }
}

There are fuller discussions on this - google for C# and WM_SETREDRAW, e.g.

C# Jitter

Suspending Layouts

And to whom it may concern, this is similar example in VB:

Public Module Extensions
    <DllImport("user32.dll")>
    Private Function SendMessage(ByVal hWnd As IntPtr, ByVal Msg As Integer, ByVal wParam As Boolean, ByVal lParam As IntPtr) As Integer
    End Function

    Private Const WM_SETREDRAW As Integer = 11

    ' Extension methods for Control
    <Extension()>
    Public Sub ResumeDrawing(ByVal Target As Control, ByVal Redraw As Boolean)
        SendMessage(Target.Handle, WM_SETREDRAW, True, 0)
        If Redraw Then
            Target.Refresh()
        End If
    End Sub

    <Extension()>
    Public Sub SuspendDrawing(ByVal Target As Control)
        SendMessage(Target.Handle, WM_SETREDRAW, False, 0)
    End Sub

    <Extension()>
    Public Sub ResumeDrawing(ByVal Target As Control)
        ResumeDrawing(Target, True)
    End Sub
End Module

There is a built in.

Use android:weightSum property to the parent LinearLayout and give value 3. Then in the children LinearLayout use android:layout_weight 2 and 1 respectively. Then in the First Chil LinearLayout use android:layout_gravity="center_vertical". As shown in the following code

<LinearLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:weightSum="3"
                    android:orientation="horizontal">

                    <LinearLayout

                        android:layout_weight="2"
                        android:layout_gravity="center_vertical"
                        android:orientation="horizontal">
                        <TextView

                            android:layout_width="wrap_content"
                            android:layout_height="wrap_content"
                            android:text="00"
                            android:textColor="@color/red"
                            android:textSize="@dimen/default_text_size"
                            />
                          <TextView
                            android:id="@+id/status_text"
                            android:layout_width="wrap_content"
                            android:layout_height="wrap_content"
                            android:text="00"
                            android:textColor="@color/red"
                            android:textSize="@dimen/default_text_size"
                            />
                    </LinearLayout>
                    <LinearLayout
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:layout_weight="1">
                        <Button
                          android:layout_width="fill_parent"
                          android:layout_height="wrap_content"

                </LinearLayout>

To undo the most recent commit I do this:

First:

git log

get the very latest SHA id to undo.

git revert SHA

That will create a new commit that does the exact opposite of your commit. Then you can push this new commit to bring your app to the state it was before, and your git history will show these changes accordingly.

This is good for an immediate redo of something you just committed, which I find is more often the case for me.

As Mike metioned, you can also do this:

git revert HEAD

Use String.format (or java.util.Formatter):

Timestamp timestamp = ...
String.format("%1$TD %1$TT", timestamp)

EDIT:
please see the documentation of Formatter to know what TD and TT means: click on java.util.Formatter

The first 'T' stands for:

't', 'T'    date/time   Prefix for date and time conversion characters.

and the character following that 'T':

'T'     Time formatted for the 24-hour clock as "%tH:%tM:%tS".
'D'     Date formatted as "%tm/%td/%ty". 

• commit() is synchronously, apply() is asynchronous

• apply() is void function.

• commit() returns true if the new values were successfully written to persistent storage.

• apply() guarantees complete before switching states , you don't need to worry about Android component lifecycles

If you dont use value returned from commit() and you're using commit() from main thread, use apply() instead of commit()

Super simple answer - solved!

my full answer here it is now built in in some oracle versions.

select group_id, 
regexp_replace(
    listagg(name, ',') within group (order by name)
    ,'([^,]+)(,\1)*(,|$)', '\1\3')
from demotable
group by group_id;  

This only works if you specify the delimiter to ',' not ', ' ie works only for no spaces after the comma. If you want spaces after the comma - here is a example how.

select 
replace(
    regexp_replace(
     regexp_replace('BBall, BBall, BBall, Football, Ice Hockey ',',\s*',',')            
    ,'([^,]+)(,\1)*(,|$)', '\1\3')
,',',', ') 
from dual

gives BBall, Football, Ice Hockey

# Your current setup
data_list = [-5, -23, 5, 0, 23, -6, 23, 67]
new_list  = []

# Sort function
for i in data_list:
    new_list = [ x for x in new_list if i > x ] + [i] + [ x for x in new_list if i <= x ]

If you only want it to iterate over your HashMap, no need for a list:

HashMap<Integer, String> map = new HashMap<Integer, String>();
map.put (1, "Mark");
map.put (2, "Tarryn");
for (String s : map.values()) {
    System.out.println(s);
}

Of course, if you want to modify your map structurally (i.e. more than only changing the value for an existing key) while iterating, then you better use the "copy to ArrayList" method, since otherwise you'll get a ConcurrentModificationException. Or export as an array:

HashMap<Integer, String> map = new HashMap<Integer, String>();
map.put (1, "Mark");
map.put (2, "Tarryn");
for (String s : map.values().toArray(new String[]{})) {
    System.out.println(s);
}

One option is to use do.call():

 > do.call(rbind, a)
      [,1] [,2] [,3] [,4] [,5] [,6]
 [1,]    1    1    2    3    4    5
 [2,]    2    1    2    3    4    5
 [3,]    3    1    2    3    4    5
 [4,]    4    1    2    3    4    5
 [5,]    5    1    2    3    4    5
 [6,]    6    1    2    3    4    5
 [7,]    7    1    2    3    4    5
 [8,]    8    1    2    3    4    5
 [9,]    9    1    2    3    4    5
[10,]   10    1    2    3    4    5

You need to install C compiler, C/C++ extension, configure launch.json and tasks.json to be able to debug C code.

This article would guide you how to do it: https://medium.com/@jerrygoyal/run-debug-intellisense-c-c-in-vscode-within-5-minutes-3ed956e059d6

Since you want to pivot multiple columns of data, I would first suggest unpivoting the result, score and grade columns so you don't have multiple columns but you will have multiple rows.

Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:

select ratio, col, value
from GRAND_TOTALS
cross apply
(
  select 'result', cast(result as varchar(10)) union all
  select 'score', cast(score as varchar(10)) union all
  select 'grade', grade
) c(col, value)

See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:

select ratio = col,
  [current ratio], [gearing ratio], [performance ratio], total
from
(
  select ratio, col, value
  from GRAND_TOTALS
  cross apply
  (
    select 'result', cast(result as varchar(10)) union all
    select 'score', cast(score as varchar(10)) union all
    select 'grade', grade
  ) c(col, value)
) d
pivot
(
  max(value)
  for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;

See SQL Fiddle with Demo. This will give you the result:

|  RATIO | CURRENT RATIO | GEARING RATIO | PERFORMANCE RATIO |     TOTAL |
|--------|---------------|---------------|-------------------|-----------|
|  grade |          Good |          Good |      Satisfactory |      Good |
| result |       1.29400 |       0.33840 |           0.04270 |    (null) |
|  score |      60.00000 |      70.00000 |          50.00000 | 180.00000 |

Although post is old I had the same problem with mingw32 vers 4.8.1 on 2015/02/13. Compiling using Eclipse CDT failed with this message. Trying from command line with -v option also failed. I was also missing the cc1plus executable.

The cause: I downloaded the command line and graphical installer from the mingw32 site. I used this to do my initial install of mingw32. Using the GUI I selected the base tools, selecting both the c and c++ compilers.

This installer did an incomplete install of the 32 bit c++ compiler. I had the g++ and cpp files but not the cc1plus executable. Trying to do an 'update' failed because the installer assumed I had everything installed.

To fix I found these sites: http://mingw-w64.sourceforge.net/ http://sourceforge.net/projects/mingw-w64/ I downloaded and ran this 'online install'. Sure enough this one contained the missing files. I modified my PATH variable and pointed to the 'bin' folder containing the g++ executable. Rebooted. Installed 64 bit Eclipse. Opened Eclipse and the 'Hello World' c++ program compiled, executed, and debugged properly.

Note: the 64bit installer seems to default to UNIX settings. Why can't an installer determine the OS??? Make sure to change them.

I spent an entire evening dealing with this. Hope this helps someone.

This can be done easily in 3 steps using SourceTree.

1. Temporarily commit everything you don't want stashed.
2. Git add everything else, then stash it.
3. Pop your temporary commit by running git reset, targetting the commit before your temporary one.

This can all be done in a matter of seconds in SourceTree, where you can just click on the files (or even individual lines) you want to add. Once added, just commit them to a temporary commit. Next, click the checkbox to add all changes, then click stash to stash everything. With the stashed changes out of the way, glance over at your commit list and note the hash for the commit before your temporary commit, then run 'git reset hash_b4_temp_commit', which is basically like "popping" the commit by resetting your branch to the commit right before it. Now, you're left with just the stuff you didn't want stashed.

Install as npm install font-awesome --save-dev

In your development less file, you can either import the whole font awesome less using @import "node_modules/font-awesome/less/font-awesome.less", or look in that file and import just the components that you need. I think this is the minimum for basic icons:

/* adjust path as needed */
@fa_path: "../node_modules/font-awesome/less";
@import "@{fa_path}/variables.less";
@import "@{fa_path}/mixins.less";
@import "@{fa_path}/path.less";
@import "@{fa_path}/core.less";
@import "@{fa_path}/icons.less";

As a note, you still aren't going to save that many bytes by doing this. Either way, you're going to end up including between 2-3k lines of unminified CSS.

You'll also need to serve the fonts themselves from a folder called/fonts/ in your public directory. You could just copy them there with a simple gulp task, for example:

gulp.task('fonts', function() {
  return gulp.src('node_modules/font-awesome/fonts/*')
    .pipe(gulp.dest('public/fonts'))
})

You want $_SERVER['REQUEST_URI']. From the docs:

'REQUEST_URI'

The URI which was given in order to access this page; for instance, '/index.html'.

It points to your top level output directory (which by default is target):

https://web.archive.org/web/20150527103929/http://docs.codehaus.org/display/MAVENUSER/MavenPropertiesGuide

EDIT: As has been pointed out, Codehaus is now sadly defunct. You can find details about these properties from Sonatype here:

If you are ever trying to reference output directories in Maven, you should never use a literal value like target/classes. Instead you should use property references to refer to these directories.

    project.build.sourceDirectory
    project.build.scriptSourceDirectory
    project.build.testSourceDirectory
    project.build.outputDirectory
    project.build.testOutputDirectory
    project.build.directory

sourceDirectory, scriptSourceDirectory, and testSourceDirectory provide access to the source directories for the project. outputDirectory and testOutputDirectory provide access to the directories where Maven is going to put bytecode or other build output. directory refers to the directory which contains all of these output directories.
