You can change your approach slightly - use Console.ReadKey() to stop your app, but do your work in a background thread:

static void Main(string[] args)
{
    var myWorker = new MyWorker();
    myWorker.DoStuff();
    Console.WriteLine("Press any key to stop...");
    Console.ReadKey();
}

In the myWorker.DoStuff() function you would then invoke another function on a background thread (using Action<>() or Func<>() is an easy way to do it), then immediately return.

That worked for me in Swift 5 like a charm, just add it to your viewDidLoad()

self.navigationItem.setHidesBackButton(true, animated: true)

Yes, you can, without adding a new column. You have to be careful to do it correctly in order to avoid corrupting the database, so you should completely back up your database before trying this.

for your specific example:

CREATE TABLE child(
  id INTEGER PRIMARY KEY,
  parent_id INTEGER,
  description TEXT
);

--- create the table we want to reference
create table parent(id integer not null primary key);

--- now we add the foreign key
pragma writable_schema=1;
update SQLITE_MASTER set sql = replace(sql, 'description TEXT)',
    'description TEXT, foreign key (parent_id) references parent(id))'
) where name = 'child' and type = 'table';

--- test the foreign key
pragma foreign_keys=on;
insert into parent values(1);
insert into child values(1, 1, 'hi'); --- works
insert into child values(2, 2, 'bye'); --- fails, foreign key violation

or more generally:

pragma writable_schema=1;

// replace the entire table's SQL definition, where new_sql_definition contains the foreign key clause you want to add
UPDATE SQLITE_MASTER SET SQL = new_sql_definition where name = 'child' and type = 'table';

// alternatively, you might find it easier to use replace, if you can match the exact end of the sql definition
// for example, if the last column was my_last_column integer not null:
UPDATE SQLITE_MASTER SET SQL = replace(sql, 'my_last_column integer not null', 'my_last_column integer not null, foreign key (col1, col2) references other_table(col1, col2)') where name = 'child' and type = 'table';

pragma writable_schema=0;

Either way, you'll probably want to first see what the SQL definition is before you make any changes:

select sql from SQLITE_MASTER where name = 'child' and type = 'table';

If you use the replace() approach, you may find it helpful, before executing, to first test your replace() command by running:

select replace(sql, ...) from SQLITE_MASTER where name = 'child' and type = 'table';

this type of error usually occur when you try to access data through the index in which data data has not been assign. for example

//assign of data in to array
for(int i=0; i<10; i++){
   arr[i]=i;
}
//accessing of data through array index
for(int i=10; i>=0; i--){
cout << arr[i];
}

the code will give error (vector subscript out of range) because you are accessing the arr[10] which has not been assign yet.

When your form is maximized, set its minimum size = max size, so user cannot resize it.

    this.WindowState = FormWindowState.Maximized;
    this.MinimumSize = this.Size;
    this.MaximumSize = this.Size;

If you give display table property in css some div bootstrap hidden class will not effect on that div

It is CMD + P (or CTRL + P) by default. However the keyboard bindings may differ according to your preferences.

To know your bindings go to the "Keyboard Shortcuts" settings and search for "Go to File"

Received this same error on SQL Server 2017 trying to link to Oracle 12c. We were able to use Oracle's SQL Developer to connect to the source database, but the linked server kept throwing the 7302 error.

In the end, we stopped all SQL Services, then re-installed the ODAC components. Started the SQL Services back up and voila!

The official pattern to implement IDisposable is hard to understand. I believe this one is better:

public class BetterDisposableClass : IDisposable {

  public void Dispose() {
    CleanUpManagedResources();
    CleanUpNativeResources();
    GC.SuppressFinalize(this);
  }

  protected virtual void CleanUpManagedResources() { 
    // ...
  }
  protected virtual void CleanUpNativeResources() {
    // ...
  }

  ~BetterDisposableClass() {
    CleanUpNativeResources();
  }

}

An even better solution is to have a rule that you always have to create a wrapper class for any unmanaged resource that you need to handle:

public class NativeDisposable : IDisposable {

  public void Dispose() {
    CleanUpNativeResource();
    GC.SuppressFinalize(this);
  }

  protected virtual void CleanUpNativeResource() {
    // ...
  }

  ~NativeDisposable() {
    CleanUpNativeResource();
  }

}

With SafeHandle and its derivatives, these classes should be very rare.

The result for disposable classes that don't deal directly with unmanaged resources, even in the presence of inheritance, is powerful: they don't need to be concerned with unmanaged resources anymore. They'll be simple to implement and to understand:

public class ManagedDisposable : IDisposable {

  public virtual void Dispose() {
    // dispose of managed resources
  }

}

Date d=new Date(new Date().getTime()+28800000);
String s=new SimpleDateFormat("dd/MM/yyyy HH:mm:ss").format(d);

HH will return 0-23 for hours.

kk will return 1-24 for hours.

See more here: Customizing Formats

use method setIs24HourView(Boolean is24HourView) to set time picker to set 24 hour view.

I agree it is generally preferable to use an Array for this.

However, this can also be accomplished in JavaScript by simply adding properties to the current scope (the global scope, if top-level code; the function scope, if within a function) by simply using this – which always refers to the current scope.

for (var i = 0; i < coords.length; ++i) {
    this["marker"+i] = "some stuff";
}

You can later retrieve the stored values (if you are within the same scope as when they were set):

var foo = this.marker0;
console.log(foo); // "some stuff"

This slightly odd feature of JavaScript is rarely used (with good reason), but in certain situations it can be useful.

If variable you need could be boolean false - eg. when no records are returned from database or array - when records are returned, you can do following:

foreach (($result ? $result : array()) as $item)
    echo $item;

Approach with cast((Array)$result) produces an array of count 1 when variable is boolean false which isn't what you probably want.

If you can use scp instead of ftp, the -r option will do this for you. I would check to see whether you can use a more modern file transfer mechanism than FTP.

moveBus() is getting called before initialize(). Try putting that line at the end of your initialize() function. Also Lat/Lon 0,0 is off the map (it's coordinates, not pixels), so you can't see it when it moves. Try 54,54. If you want the center of the map to move to the new location, use panTo().

It is easy to convert your OrderedDict to a regular Dict like this:

dict(OrderedDict([('method', 'constant'), ('data', '1.225')]))

If you have to store it as a string in your database, using JSON is the way to go. That is also quite simple, and you don't even have to worry about converting to a regular dict:

import json
d = OrderedDict([('method', 'constant'), ('data', '1.225')])
dString = json.dumps(d)

Or dump the data directly to a file:

with open('outFile.txt','w') as o:
    json.dump(d, o)

Some time you miss below line. add this router will understand this.

module.exports = router;

I had a span that would create a popup. If I used "click touchstart" it would trigger parts of the popup during the touchend. I fixed this by making the span "click touchend".

Your error is because you have:

     JOIN user ON article.author_id = user.id
LEFT JOIN user ON article.modified_by = user.id

You have two instances of the same table, but the database can't determine which is which. To fix this, you need to use table aliases:

     JOIN USER u ON article.author_id = u.id
LEFT JOIN USER u2 ON article.modified_by = u2.id

It's good habit to always alias your tables, unless you like writing the full table name all the time when you don't have situations like these.

The next issues to address will be:

SELECT article.* , section.title, category.title, user.name, user.name

1) Never use SELECT * - always spell out the columns you want, even if it is the entire table. Read this SO Question to understand why.

2) You'll get ambiguous column errors relating to the user.name columns because again, the database can't tell which table instance to pull data from. Using table aliases fixes the issue:

SELECT article.* , section.title, category.title, u.name, u2.name

You can put @JsonSerialize(using = CustomDateSerializer.class) over any date field of object to be serialized.

public class CustomDateSerializer extends SerializerBase<Date> {

    public CustomDateSerializer() {
        super(Date.class, true);
    }

    @Override
    public void serialize(Date value, JsonGenerator jgen, SerializerProvider provider)
        throws IOException, JsonProcessingException {
        SimpleDateFormat formatter = new SimpleDateFormat("EEE MMM dd yyyy HH:mm:ss 'GMT'ZZZ (z)");
        String format = formatter.format(value);
        jgen.writeString(format);
    }

}

Add position:fixed. Then the cover is fixed over the whole screen, also when you scroll.
And add maybe also margin: 0; padding:0; so it wont have some space's around the cover.

#dimScreen
{
    position:fixed;
    padding:0;
    margin:0;

    top:0;
    left:0;

    width: 100%;
    height: 100%;
    background:rgba(255,255,255,0.5);
}

And if it shouldn't stick on the screen fixed, use position:absolute;

CSS Tricks have also an interesting article about fullscreen property.

Edit:
Just came across this answer, so I wanted to add some additional things.
Like Daniel Allen Langdon mentioned in the comment, add top:0; left:0; to be sure, the cover sticks on the very top and left of the screen.

If you some elements are at the top of the cover (so it doesn't cover everything), then add z-index. The higher the number, the more levels it covers.

UTF-8 friendly version of the simple function posted above by Gino:

function stripAccents($str) {

}

Had to come to this because my php document was UTF-8 encoded.

Hope it helps.

keep dividing by ten until you get zero, then just output the number of divisions.

int intLen(int x)
{
  if(!x) return 1;
  int i;
  for(i=0; x!=0; ++i)
  {
    x /= 10;
  }
  return i;
}

Slicing data with pandas

Given a dataframe like this:

    RPT_Date  STK_ID STK_Name  sales
0 1980-01-01       0   Arthur      0
1 1980-01-02       1    Beate      4
2 1980-01-03       2    Cecil      2
3 1980-01-04       3     Dana      8
4 1980-01-05       4     Eric      4
5 1980-01-06       5    Fidel      5
6 1980-01-07       6   George      4
7 1980-01-08       7     Hans      7
8 1980-01-09       8   Ingrid      7
9 1980-01-10       9    Jones      4

There are multiple ways of selecting or slicing the data.

Using .isin

The most obvious is the .isin feature. You can create a mask that gives you a series of True/False statements, which can be applied to a dataframe like this:

mask = df['STK_ID'].isin([4, 2, 6])

mask
0    False
1    False
2     True
3    False
4     True
5    False
6     True
7    False
8    False
9    False
Name: STK_ID, dtype: bool

df[mask]
    RPT_Date  STK_ID STK_Name  sales
2 1980-01-03       2    Cecil      2
4 1980-01-05       4     Eric      4
6 1980-01-07       6   George      4

Masking is the ad-hoc solution to the problem, but does not always perform well in terms of speed and memory.

With indexing

By setting the index to the STK_ID column, we can use the pandas builtin slicing object .loc

df.set_index('STK_ID', inplace=True)
         RPT_Date STK_Name  sales
STK_ID                           
0      1980-01-01   Arthur      0
1      1980-01-02    Beate      4
2      1980-01-03    Cecil      2
3      1980-01-04     Dana      8
4      1980-01-05     Eric      4
5      1980-01-06    Fidel      5
6      1980-01-07   George      4
7      1980-01-08     Hans      7
8      1980-01-09   Ingrid      7
9      1980-01-10    Jones      4

df.loc[[4, 2, 6]]
         RPT_Date STK_Name  sales
STK_ID                           
4      1980-01-05     Eric      4
2      1980-01-03    Cecil      2
6      1980-01-07   George      4

This is the fast way of doing it, even if the indexing can take a little while, it saves time if you want to do multiple queries like this.

Merging dataframes

This can also be done by merging dataframes. This would fit more for a scenario where you have a lot more data than in these examples.

stkid_df = pd.DataFrame({"STK_ID": [4,2,6]})
df.merge(stkid_df, on='STK_ID')
   STK_ID   RPT_Date STK_Name  sales
0       2 1980-01-03    Cecil      2
1       4 1980-01-05     Eric      4
2       6 1980-01-07   George      4

Note

All the above methods work even if there are multiple rows with the same 'STK_ID'

Use Long.parseLong()

 Long.parseLong("0", 10)        // returns 0L
 Long.parseLong("473", 10)      // returns 473L
 Long.parseLong("-0", 10)       // returns 0L
 Long.parseLong("-FF", 16)      // returns -255L
 Long.parseLong("1100110", 2)   // returns 102L
 Long.parseLong("99", 8)        // throws a NumberFormatException
 Long.parseLong("Hazelnut", 10) // throws a NumberFormatException
 Long.parseLong("Hazelnut", 36) // returns 1356099454469L
 Long.parseLong("999")          // returns 999L

Use itertools.combinations(mylist, 2)

mylist = range(5)
for x,y in itertools.combinations(mylist, 2):
    print x,y

0 1
0 2
0 3
0 4
1 2
1 3
1 4
2 3
2 4
3 4

No, you can only get to the interior color of a cell by using a Macro. I am afraid. It's really easy to do (cell.interior.color) so unless you have a requirement that restricts you from using VBA, I say go for it.

Assuming you're passing in strings rather than integers, try casting the arguments to integers:

def example(arg1, arg2, arg3):
     if int(arg1) == 1 and int(arg2) == 2 and int(arg3) == 3:
          print("Example Text")

(Edited to emphasize I'm not asking for clarification; I was trying to be diplomatic in my answer. )

You can use it like this, I hope you wont get outdated message now.

  <td valign="top" style="white-space:nowrap" width="237">

As pointed by @ThiefMaster it is recommended to put width and valign to CSS (note: CSS calls it vertical-align).

1)

<td style="white-space:nowrap; width:237px; vertical-align:top;">

2) We can make a CSS class like this, it is more elegant way

In style section

.td-some-name
{
  white-space:nowrap;
  width:237px;
  vertical-align:top;
}

In HTML section

<td class="td-some-name">

A rather roundabout way, just for completeness:

 for /f "delims=" %i in ('type CON') do set inp=%i

Of course that requires ^Z as a terminator, and so the Johannes answer is better in all practical ways.

The following works for me:

git diff master:foo foo

In the past, it may have been:

git diff foo master:foo

An interface defines behavior. For example, a Vehicle interface might define the move() method.

A Car is a Vehicle, but has additional behavior. For example, the Car interface might define the startEngine() method. Since a Car is also a Vehicle, the Car interface extends the Vehicle interface, and thus defines two methods: move() (inherited) and startEngine().

The Car interface doesn't have any method implementation. If you create a class (Volkswagen) that implements Car, it will have to provide implementations for all the methods of its interface: move() and startEngine().

An interface may not implement any other interface. It can only extend it.

I don't get the point with the formating of the file, since you only want to iterate through folders... Are you looking for something like this?

cd parent
find . -type d | while read d; do
   ls $d/
done

Given an iPhone 5s and not yet having received a 64 bit version of a third party library, I had to go back to 32 bit mode with the latest Xcode (prior to 5.1 it didn't complain).

I fixed this by deleting arm64 from the Valid Architectures list and then setting Build Active Architecture Only to NO. It seems to me this makes more sense than the other way around as shown above. I'm posting in case other people couldn't get any of the above solutions to work for them.

For the question

How can i run a jar file in command prompt but with arguments

.

To pass arguments to the jar file at the time of execution

java -jar myjar.jar arg1 arg2

In the main() method of "Main-Class" [mentioned in the manifest.mft file]of your JAR file. you can retrieve them like this:

String arg1 = args[0];
String arg2 = args[1];

You could base something on the ObjectDumper code that ships with the Linq samples.
Have also a look at the answer of this related question to get a sample.

According to the UI dialog documentation, the dialog plugin generates something like this:

<div class="ui-dialog ui-widget ui-widget-content ui-corner-all ui-draggable ui-resizable">
   <div class="ui-dialog-titlebar ui-widget-header ui-corner-all ui-helper-clearfix">
      <span id="ui-dialog-title-dialog" class="ui-dialog-title">Dialog title</span>
      <a class="ui-dialog-titlebar-close ui-corner-all" href="#"><span class="ui-icon ui-icon-closethick">close</span></a>
   </div>
   <div class="ui-dialog-content ui-widget-content" id="dialog_style1">
      <p>One content</p>
   </div>
</div>

That means what you can add to any class to exactly to first or second dialog using jQuery's closest() method. For example:

$('#dialog_style1').closest('.ui-dialog').addClass('dialog_style1');

$('#dialog_style2').closest('.ui-dialog').addClass('dialog_style2');

and then CSS it.

After hours of research, I finally found a solution to take a screenshot of an element, even if the origin-clean FLAG is set (to prevent XSS), that´s why you can even capture for example Google Maps (in my case). I wrote a universal function to get a screenshot. The only thing you need in addition is the html2canvas library (https://html2canvas.hertzen.com/).

Example:

getScreenshotOfElement($("div#toBeCaptured").get(0), 0, 0, 100, 100, function(data) {
    // in the data variable there is the base64 image
    // exmaple for displaying the image in an <img>
    $("img#captured").attr("src", "data:image/png;base64,"+data);
});

Keep in mind console.log() and alert() won´t generate output if the size of the image is great.

Function:

function getScreenshotOfElement(element, posX, posY, width, height, callback) {
    html2canvas(element, {
        onrendered: function (canvas) {
            var context = canvas.getContext('2d');
            var imageData = context.getImageData(posX, posY, width, height).data;
            var outputCanvas = document.createElement('canvas');
            var outputContext = outputCanvas.getContext('2d');
            outputCanvas.width = width;
            outputCanvas.height = height;

            var idata = outputContext.createImageData(width, height);
            idata.data.set(imageData);
            outputContext.putImageData(idata, 0, 0);
            callback(outputCanvas.toDataURL().replace("data:image/png;base64,", ""));
        },
        width: width,
        height: height,
        useCORS: true,
        taintTest: false,
        allowTaint: false
    });
}

Apache Commons Lang has a method to split a string with whitespace characters as delimiters:

StringUtils.split("abc def")

http://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/StringUtils.html#split(java.lang.String)

This might be easier to use than a regex pattern.

you can achieve this by doing

<item
    android:id="@+id/menus"
    android:actionProviderClass="@android:style/Widget.Holo.ActionButton.Overflow"
    android:icon="@drawable/your_icon"
    android:showAsAction="always">
  <item android:id="@+id/Bugreport"
   android:title="@string/option_bugreport" />

  <item android:id="@+id/Info"
  android:title="@string/option_info" />

 <item android:id="@+id/About"
   android:title="@string/option_about" />
  </item>

For me, the user was mongod instead of mongodb

sudo chown mongod:mongod /newlocation

You can see the logs for errors if the service fails:

/var/log/mongodb/mongod.log

use mode1.name() or String.valueOf(Modes.mode1)

Another solution could be.. find the location of composer.phar file in your computer. If composer is installed successfully then it can be found in the installed directory.

Copy that location & instead of composer.phar in the command line, put the entire path there.

It also worked for me!

Wrapping components with braces if no default exports:

import {MyNavbar} from './comp/my-navbar.jsx';

or import multiple components from single module file

import {MyNavbar1, MyNavbar2} from './module';

Final answer was a combination of two of the above (I've upvoted both to show my appreciation!):

select case 
   when exists (
      SELECT 1 
      FROM Sys.columns c 
      WHERE c.[object_id] = OBJECT_ID('dbo.Tags') 
         AND c.name = 'ModifiedByUserId'
   ) 
   then 1 
   else 0 
end

You can also do it "the joiner way" by inserting "U+2060 Word Joiner".

If Accept-Charset permits, the unicode character itself can be inserted directly into the HTML output.

Otherwise, it can be done using entity encoding. E.g. to join the text red-brown, use:

red-⁠brown

or (decimal equivalent):

red-⁠brown

. Another usable character is "U+FEFF Zero Width No-break Space"^{[⁠ ⁠1 ]}:

red-brown

and (decimal equivalent):

red-brown

^{[1]: Note that while this method still works in major browsers like Chrome, it has been deprecated since Unicode 3.2.}

Comparison of "the joiner way" with "U+2011 Non-breaking Hyphen":

• The word joiner can be used for all other characters, not just hyphens.

• When using the word joiner, most renderers will rasterize the text identically. On Chrome, FireFox, IE, and Opera, the rendering of normal hyphens, eg:

  a-b-c-d-e-f-g-h-i-j-k-l-m-n-o-p-q-r-s-t-u-v-w-x-y-z

  is identical to the rendering of normal hyphens (with U+2060 Word Joiner), eg:

  a-⁠b-⁠c-⁠d-⁠e-⁠f-⁠g-⁠h-⁠i-⁠j-⁠k-⁠l-⁠m-⁠n-⁠o-⁠p-⁠q-⁠r-⁠s-⁠t-⁠u-⁠v-⁠w-⁠x-⁠y-⁠z

  while the above two renders differ from the rendering of "Non-breaking Hyphen", eg:

  a‑b‑c‑d‑e‑f‑g‑h‑i‑j‑k‑l‑m‑n‑o‑p‑q‑r‑s‑t‑u‑v‑w‑x‑y‑z

  . (The extent of the difference is browser-dependent and font-dependent. E.g. when using a font declaration of "arial", Firefox and IE11 show relatively huge variations, while Chrome and Opera show smaller variations.)

Comparison of "the joiner way" with <span class=c1></span> (CSS .c1 {white-space:nowrap;}) and <nobr></nobr>:

• The word joiner can be used for situations where usage of HTML tags is restricted, e.g. forms of websites and forums.

• On the spectrum of presentation and content, majority will consider the word joiner to be closer to content, when compared to tags.

^{• As tested on Windows 8.1 Core 64-bit using:
    • IE 11.0.9600.18205
    • Firefox 43.0.4
    • Chrome 48.0.2564.109 (Official Build) m (32-bit)
    • Opera 35.0.2066.92}

I always use the ISO 8601 format (e.g. 2008-10-31T15:07:38.6875000-05:00) -- date.ToString("o"). It is the XSD date format as well. That is the preferred format and a Standard Date and Time Format string, although you can use a manual format string if necessary if you don't want the 'T' between the date and time: date.ToString("yyyy-MM-dd HH:mm:ss");

EDIT: If you are using a generated class from an XSD or Web Service, you can just assign the DateTime instance directly to the class property. If you are writing XML text, then use the above.

You can simply use:

mvn --settings YourOwnSettings.xml clean install

or

mvn -s YourOwnSettings.xml clean install

<script src="https://cdn.datatables.net/1.10.22/js/jquery.dataTables.min.js"defer</script>

Add Defer to the end of your Script tag, it worked for me (;

Everything needs to be loaded in the correct order (:

The following way has helped me (includes react-hot, babel loaders and es2015, react presets):

loaders: [
      {
        test: /\.jsx?$/,
        exclude: /node_modules/,
        loaders: ['react-hot', 'babel?presets[]=es2015&presets[]=react']
      }
]

I interpreted the question as using cast on a subquery. Yes, you can do that:

select cast((<subquery>) as <newtype>)

If you do so, then you need to be sure that the returns one row and one value. And, since it returns one value, you could put the cast in the subquery instead:

select (select cast(<val> as <newtype>) . . .)

I have a single-page app in our company intranet where certain date fields need to be "blocked" under certain circumstances. Those date fields have a datepicker binding.

Making the fields read-only wasn't enough to block the fields, as datepicker still triggers when the field receives focus.

Disabling the field (or disabling datepicker) have side effects with serialize() or serializeArray().

One of the options was to unbind datepicker from those fields and making them "normal" fields. But one easiest solution is to make the field (or fields) read-only and to avoid datepicker from acting when receive focus.

$('#datefield').attr('readonly',true).datepicker("option", "showOn", "off");

A virtual constructor is not possible but virtual destructor is possible. Let us experiment.......

#include <iostream>

using namespace std;

class Base
{
public:
    Base(){
        cout << "Base Constructor Called\n";
    }
    ~Base(){
        cout << "Base Destructor called\n";
    }
};

class Derived1: public Base
{
public:
    Derived1(){
        cout << "Derived constructor called\n";
    }
    ~Derived1(){
        cout << "Derived destructor called\n";
    }
};

int main()
{
    Base *b = new Derived1();
    delete b;
}

The above code output the following:

Base Constructor Called
Derived constructor called
Base Destructor called

The construction of derived object follow the construction rule but when we delete the "b" pointer(base pointer) we have found that only the base destructor is called. But this must not happen. To do the appropriate thing, we have to make the base destructor virtual. Now let see what happens in the following:

#include <iostream>

using namespace std;

class Base
{ 
public:
    Base(){
        cout << "Base Constructor Called\n";
    }
    virtual ~Base(){
        cout << "Base Destructor called\n";
    }
};

class Derived1: public Base
{
public:
    Derived1(){
        cout << "Derived constructor called\n";
    }
    ~Derived1(){
        cout << "Derived destructor called\n";
    }
};

int main()
{
    Base *b = new Derived1();
    delete b;
}

The output changed as following:

Base Constructor Called
Derived Constructor called
Derived destructor called
Base destructor called

So the destruction of the base pointer (which takes an allocation on derived object!) follows the destruction rule, i.e first the Derived, then the Base. On the other hand, there is nothing like a virtual constructor.

You can normally check for ASCII letters or numbers using simple conditions

if ((ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z'))
{
    /*This is an alphabet*/
}

For digits you can use

if (ch >= '0' && ch <= '9')
{
    /*It is a digit*/
}

But since characters in C are internally treated as ASCII values you can also use ASCII values to check the same.

How to check if a character is number or letter

1. Lowest common denominator max URL length among popular web browsers: 2,083 (Internet Explorer)

2. http://dev.mysql.com/doc/refman/5.0/en/char.html
   Values in VARCHAR columns are variable-length strings. The length can be specified as a value from 0 to 255 before MySQL 5.0.3, and 0 to 65,535 in 5.0.3 and later versions. The effective maximum length of a VARCHAR in MySQL 5.0.3 and later is subject to the maximum row size (65,535 bytes, which is shared among all columns) and the character set used.

3. So ...
   < MySQL 5.0.3 use TEXT
   or
   >= MySQL 5.0.3 use VARCHAR(2083)

The brackets can be used when column names are reserved words.

If you are programatically generating the SQL statement from a collection of column names you don't control, then you can avoid problems by always using the brackets.

CSTR({number_field}, 0, '')

The second placeholder is for decimals.

The last placeholder is for thousands separator.

This works for me on git version 1.8.5.2:

git diff stash HEAD

If you really want to force-download all dependencies, you can try to re-initialise the entire maven repository. Like in this article already described, you could use:

mvn -Dmaven.repo.local=$HOME/.my/other/repository clean install

MySQL can record linebreaks just fine in most cases, but the problem is, you need <br /> tags in the actual string for your browser to show the breaks. Since you mentioned PHP, you can use the nl2br() function to convert a linebreak character ("\n") into HTML <br /> tag.

Just use it like this:

<?php
echo nl2br("Hello, World!\n I hate you so much");
?>

Output (in HTML):

Hello, World!<br>I hate you so much

Here's a link to the manual: http://php.net/manual/en/function.nl2br.php

I use often abstract classes in conjuction with Template method pattern.
In main abstract class I wrote the skeleton of main algorithm and make abstract methods as hooks where suclasses can make a specific implementation; I used often when writing data parser (or processor) that need to read data from one different place (file, database or some other sources), have similar processing step (maybe small differences) and different output.
This pattern looks like Strategy pattern but it give you less granularity and can degradated to a difficult mantainable code if main code grow too much or too exceptions from main flow are required (this considerations came from my experience).
Just a small example:

abstract class MainProcess {
  public static class Metrics {
    int skipped;
    int processed;
    int stored;
    int error;
  }
  private Metrics metrics;
  protected abstract Iterator<Item> readObjectsFromSource();
  protected abstract boolean storeItem(Item item);
  protected Item processItem(Item item) {
    /* do something on item and return it to store, or null to skip */
    return item;
  }
  public Metrics getMetrics() {
    return metrics;
  }
  /* Main method */
  final public void process() {
    this.metrics = new Metrics();
    Iterator<Item> items = readObjectsFromSource();
    for(Item item : items) {
      metrics.processed++;
      item = processItem(item);
      if(null != item) {

        if(storeItem(item))
          metrics.stored++;
        else
          metrics.error++;
      }
      else {
        metrics.skipped++;
      }
    }
  } 
}

class ProcessFromDatabase extends MainProcess {
  ProcessFromDatabase(String query) {
    this.query = query;
  }
  protected Iterator<Item> readObjectsFromSource() {
    return sessionFactory.getCurrentSession().query(query).list();
  }
  protected boolean storeItem(Item item) {
    return sessionFactory.getCurrentSession().saveOrUpdate(item);
  }
}

Here another example.

Maybe EXISTS can help.

and exists (select 1 from @DocumentNames where pcd.Name like DocName+'%' or CD.DocumentName like DocName+'%')

You can, however no any table. From documentation:

For Transact-SQL functions, all data types, including CLR user-defined types and user-defined table types, are allowed except the timestamp data type.

You can use user-defined table types.

Example of user-defined table type:

CREATE TYPE TableType 
AS TABLE (LocationName VARCHAR(50))
GO 

DECLARE @myTable TableType
INSERT INTO @myTable(LocationName) VALUES('aaa')
SELECT * FROM @myTable

So what you can do is to define your table type, for example TableType and define the function which takes the parameter of this type. An example function:

CREATE FUNCTION Example( @TableName TableType READONLY)
RETURNS VARCHAR(50)
AS
BEGIN
    DECLARE @name VARCHAR(50)

    SELECT TOP 1 @name = LocationName FROM @TableName
    RETURN @name
END

The parameter has to be READONLY. And example usage:

DECLARE @myTable TableType
INSERT INTO @myTable(LocationName) VALUES('aaa')
SELECT * FROM @myTable

SELECT dbo.Example(@myTable)

Depending on what you want achieve you can modify this code.

EDIT: If you have a data in a table you may create a variable:

DECLARE @myTable TableType

And take data from your table to the variable

INSERT INTO @myTable(field_name)
SELECT field_name_2 FROM my_other_table

I know there's an answer already, but if you want your input to behave exactly like the maxlength attribute or as close as you can, use the following code:

(function($) {
 methods = {
    /*
     * addMax will take the applied element and add a javascript behavior
     * that will set the max length
     */
    addMax: function() {
        // set variables
        var
            maxlAttr = $(this).attr("maxlength"),
            maxAttR = $(this).attr("max"),
            x = 0,
            max = "";

        // If the element has maxlength apply the code.
        if (typeof maxlAttr !== typeof undefined && maxlAttr !== false) {

The simplest way to do it is to:

1) Start Excel from your batch file to open the workbook containing your macro:

EXCEL.EXE /e "c:\YourWorkbook.xls"

2) Call your macro from the workbook's Workbook_Open event, such as:

Private Sub Workbook_Open()
    Call MyMacro1          ' Call your macro
    ActiveWorkbook.Save    ' Save the current workbook, bypassing the prompt
    Application.Quit       ' Quit Excel
End Sub

This will now return the control to your batch file to do other processing.

You can use a challenge response scheme. Say the client and server both know a secret S. Then the server can be sure that the client knows the password (without giving it away) by:

1. Server sends a random number, R, to client.
2. Client sends H(R,S) back to the server (where H is a cryptographic hash function, like SHA-256)
3. Server computes H(R,S) and compares it to the client's response. If they match, the server knows the client knows the password.

Edit:

There is an issue here with the freshness of R and the fact that HTTP is stateless. This can be handled by having the server create a secret, call it Q, that only the server knows. Then the protocol goes like this:

To note, since H(R,Q) cannot be forged by the client, H(R,Q) acts as a cookie (and could therefore be implemented actually as a cookie).

Another Edit:

The previous edit to the protocol is incorrect as anyone who has observed H(R,Q) seems to be able to replay it with the correct hash. The server has to remember which R's are no longer fresh. I'm CW'ing this answer so you guys can edit away at this and work out something good.

The above code not worked for me. I found new solution :

 var pdf = new jsPDF();
 var img = new Image;
 img.onload = function() {
     pdf.addImage(this, 10, 10);
     pdf.save("test.pdf");
 };
 img.crossOrigin = "";  
 img.src = "assets/images/logo.png";

I'm prettifying the output of @Hassou's answer with:

ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/-/+/' -e '$s/+/+/'

This is much like the output of tree now:

.
+-pkcs11
+-pki
+---ca-trust
+-----extracted
+-------java
+-------openssl
+-------pem
+-----source
+-------anchors
+-profile.d
+-ssh

You can also make an alias of it:

alias ltree=$'ls -R | grep ":$" | sed -e \'s/:$//\' -e \'s/[^-][^\/]*\//--/g\' -e \'s/-/+/\' -e \'$s/+/+/\''

BTW, tree is not available in some environment, like MinGW. So the alternate is helpful.

/*

If your delimiters are slash-based, escape it:

\/*

* means "0 or more of the previous repeatable pattern", which can be a single character, a character class or a group.

In javascript you can do:

var element = document.getElementById("myid");
element.style.position = "fixed";
element.style.top = "0%";

Having consistent line endings is a good thing. For example it will not trigger unnecessary merges, albeit trivial. I have seen Visual Studio create files with mixed line endings.

Also some programs like bash (on linux) do require that .sh files are LF terminated.

To make sure this happens you can use gitattributes. It works on repository level no matter what the value of autcrlf is.

For example you can have .gitattributes like this: * text=auto

You can also be more specific per file type/extension if it did matter in your case.

Then autocrlf can convert line endings for Windows programs locally.

On a mixed C#/C++/Java/Ruby/R, Windows/Linux project this is working well. No issues so far.

This tends to happen particularly with vscode as I'd assume because of how one configures the launch.json.

Based on this answer I had to reconfigure the base path the configuration is being searched for to that of DLL's path, and since the default setting was optional it was hard to track this down on a .net core 3.1 & net 5.0 app. Here's how I've reconfigured

Program.cs:

using System;
using System.IO;
using System.Reflection;
using Microsoft.Extensions.Configuration;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Hosting;

namespace API
{
    public class Program
    {
        public static int Main(string[] args)
        {
            CreateHostBuilder(args).Build().Run();
            return 0;
        }

        public static IHostBuilder CreateHostBuilder(string[] args)
        {
            return Host.CreateDefaultBuilder(args)
            .ConfigureAppConfiguration(c =>
            {
                var codeBase = Assembly.GetExecutingAssembly().Location;
                var uri = new UriBuilder(codeBase);
                var path = Uri.UnescapeDataString(uri.Path);
                var assembyDirectory = Path.GetDirectoryName(path);
                c.SetBasePath(assembyDirectory);
            })
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.UseStartup<Startup>();
            })
            ;
        }
    }
}

I could access the configuration fine in Startup.cs:

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Model;

namespace API
{
    public class Startup
    {
        public IConfiguration Configuration { get; }

        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            var myOptions = Configuration.To<ApiConfig>();
            services.AddAuthentication(myOptions.Secret);
            services.AddControllers();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            app.UseRouting();
            app.UseAuthentication();
            app.UseAuthorization();
            app.UseEndpoints(endpoints => { endpoints.MapControllers(); });
        }
    }
}

Actually you only need to execute:

sudo chmod +x ./gradlew

It works for me! And if it is too slow, you can execute:

./gradlew clean build

For Mac/Linux debug keystore, the Android docs have:

keytool -exportcert -list -v \
-alias androiddebugkey -keystore ~/.android/debug.keystore

But there is something that may not be obvious: If you put the backslash, make sure to do a shift + return in terminal after the backslash so that the second that starts with -alias is on a new line. Simply pasting as-is will not work.

Your terminal (if successful) will look something like this:

$ keytool -exportcert -list -v \
? -alias androiddebugkey -keystore ~/.android/debug.keystore
Enter keystore password: 

The default debug password is: android

Side note: In Android Studio you can manage signing in:

A Window object is just what it sounds like: its a new Window for your application. You should use it when you want to pop up an entirely new window. I don't often use more than one Window in WPF because I prefer to put dynamic content in my main Window that changes based on user action.

A Page is a page inside your Window. It is mostly used for web-based systems like an XBAP, where you have a single browser window and different pages can be hosted in that window. It can also be used in Navigation Applications like sellmeadog said.

A UserControl is a reusable user-created control that you can add to your UI the same way you would add any other control. Usually I create a UserControl when I want to build in some custom functionality (for example, a CalendarControl), or when I have a large amount of related XAML code, such as a View when using the MVVM design pattern.

When navigating between windows, you could simply create a new Window object and show it

var NewWindow = new MyWindow();
newWindow.Show();

but like I said at the beginning of this answer, I prefer not to manage multiple windows if possible.

My preferred method of navigation is to create some dynamic content area using a ContentControl, and populate that with a UserControl containing whatever the current view is.

<Window x:Class="MyNamespace.MainWindow" ...>
    <DockPanel>
        <ContentControl x:Name="ContentArea" />
    </DockPanel>
</Window>

and in your navigate event you can simply set it using

ContentArea.Content = new MyUserControl();

But if you're working with WPF, I'd highly recommend the MVVM design pattern. I have a very basic example on my blog that illustrates how you'd navigate using MVVM, using this pattern:

<Window x:Class="SimpleMVVMExample.ApplicationView"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:SimpleMVVMExample"
        Title="Simple MVVM Example" Height="350" Width="525">

   <Window.Resources>
      <DataTemplate DataType="{x:Type local:HomeViewModel}">
         <local:HomeView /> <!-- This is a UserControl -->
      </DataTemplate>
      <DataTemplate DataType="{x:Type local:ProductsViewModel}">
         <local:ProductsView /> <!-- This is a UserControl -->
      </DataTemplate>
   </Window.Resources>

   <DockPanel>
      <!-- Navigation Buttons -->
      <Border DockPanel.Dock="Left" BorderBrush="Black"
                                    BorderThickness="0,0,1,0">
         <ItemsControl ItemsSource="{Binding PageViewModels}">
            <ItemsControl.ItemTemplate>
               <DataTemplate>
                  <Button Content="{Binding Name}"
                          Command="{Binding DataContext.ChangePageCommand,
                             RelativeSource={RelativeSource AncestorType={x:Type Window}}}"
                          CommandParameter="{Binding }"
                          Margin="2,5"/>
               </DataTemplate>
            </ItemsControl.ItemTemplate>
         </ItemsControl>
      </Border>

      <!-- Content Area -->
      <ContentControl Content="{Binding CurrentPageViewModel}" />
   </DockPanel>
</Window>

Well, you can use default branch to detect it, for a closed channel will be selected, for example: the following code will select default, channel, channel, the first select is not blocked.

func main() {
    ch := make(chan int)

    go func() {
        select {
        case <-ch:
            log.Printf("1.channel")
        default:
            log.Printf("1.default")
        }
        select {
        case <-ch:
            log.Printf("2.channel")
        }
        close(ch)
        select {
        case <-ch:
            log.Printf("3.channel")
        default:
            log.Printf("3.default")
        }
    }()
    time.Sleep(time.Second)
    ch <- 1
    time.Sleep(time.Second)
}

Prints

2018/05/24 08:00:00 1.default
2018/05/24 08:00:01 2.channel
2018/05/24 08:00:01 3.channel

The WM_CONCAT function (if included in your database, pre Oracle 11.2) or LISTAGG (starting Oracle 11.2) should do the trick nicely. For example, this gets a comma-delimited list of the table names in your schema:

select listagg(table_name, ', ') within group (order by table_name) 
  from user_tables;

or

select wm_concat(table_name) 
  from user_tables;

I had a similar problem this morning (trying to build for Android using Unity3D). I ended up uninstalling JDK9 and installing Java SE Development Kit 8u144. Hope this helps.

1. brew cask uninstall java # uninstall java9
2. brew tap homebrew/cask-versions
3. brew cask install java8 # install java8
4. touch ~/.android/repositories.cfg # without this file, error will occur on next step
5. brew cask install android-sdk

import java.util.Scanner;
public class Solution {

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        int i = scan.nextInt();
        double d = scan.nextDouble();
        String s="";
        while(scan.hasNext())
        {
            s=scan.nextLine();
        }

        System.out.println("String: " +s);
        System.out.println("Double: " + d);
        System.out.println("Int: " + i);
    }
}

It depends. If the main code is protected by an if as in:

if __name__ == '__main__':
    ...main code...

then no, you can't make Python execute that because you can't influence the automatic variable __name__.

But when all the code is in a function, then might be able to. Try

import myModule

myModule.main()

This works even when the module protects itself with a __all__.

from myModule import * might not make main visible to you, so you really need to import the module itself.

Found this out by trial and error. If your configuration specifies a ServerName, then your VirtualHost directive will need to do the same. In the following example, awesome.example.com and amazing.example.com would both be forwarded to some local service running on port 4567.

ServerName example.com:80

<VirtualHost example.com:80>
  ProxyPreserveHost On
  ProxyRequests Off
  ServerName awesome.example.com
  ServerAlias amazing.example.com
  ProxyPass / http://localhost:4567/
  ProxyPassReverse / http://localhost:4567/
</VirtualHost>

I know this doesn't exactly answer the question, but I'm putting it here because this is the top search result for Apache port forwarding. So I figure it'll help somebody someday.

1. find /usr/lib/jvm/java-1.x.x-openjdk

2. vim /etc/profile

   Prepend sudo if logged in as not-privileged user, ie. sudo vim

3. Press 'i' to get in insert mode

4. add:

   export JAVA_HOME="path that you found"
   
   export PATH=$JAVA_HOME/bin:$PATH
   

5. logout and login again, reboot, or use source /etc/profile to apply changes immediately in your current shell

It really depends on the hashing algorithm you're using. The length of the password has little to do with the length of the hash, if I remember correctly. Look up the specs on the hashing algorithm you are using, run a few tests, and truncate just above that.

because if you change your code with

def gukan(count):
    while count!=100:
      print(count)
      count=count+3;
gukan(0)

count reaches 99 and then, at the next iteration 102.

So

count != 100

never evaluates true and the loop continues forever

If you want to count up to 100 you may use

def gukan(count):
    while count <= 100:
      print(count)
      count=count+3;
gukan(0)

or (if you want 100 always printed)

def gukan(count):
    while count <= 100:
      print(count)
      count=count+3;
      if count > 100:
          count = 100
gukan(0)

As was written above, if the language you use has a JSON-library coming with it, use it to try decoding the string and catch the exception/error if it fails! If the language does not (just had such a case with FreeMarker) the following regex could at least provide some very basic validation (it's written for PHP/PCRE to be testable/usable for more users). It's not as foolproof as the accepted solution, but also not that scary =):

~^\{\s*\".*\}$|^\[\n?\{\s*\".*\}\n?\]$~s

short explanation:

// we have two possibilities in case the string is JSON
// 1. the string passed is "just" a JSON object, e.g. {"item": [], "anotheritem": "content"}
// this can be matched by the following regex which makes sure there is at least a {" at the
// beginning of the string and a } at the end of the string, whatever is inbetween is not checked!

^\{\s*\".*\}$

// OR (character "|" in the regex pattern)
// 2. the string passed is a JSON array, e.g. [{"item": "value"}, {"item": "value"}]
// which would be matched by the second part of the pattern above

^\[\n?\{\s*\".*\}\n?\]$

// the s modifier is used to make "." also match newline characters (can happen in prettyfied JSON)

if I missed something that would break this unintentionally, I'm grateful for comments!

If you have a large array and only want to see a subsection of the array you can type this into the watch window;

ptr+100,10

to show a list of the 10 elements starting at ptr[100]. Beware that the displayed array subscripts will start at [0], so you will have to remember that ptr[0] is really ptr[100] and ptr[1] is ptr[101] etc.

Give your textbox a name and then use TextBoxName.Text = String.Empty;

If you're code-golfing, I would suggest for(;;). Beyond that, while(true) has the same meaning and seems more intuitive. At any rate, most coders will likely understand both variations, so it doesn't really matter. Use what's most comfortable.

Reducing the image size before output results in something that looks sharper, in my case:

convert -density 300 a.pdf -resize 25% a.png

I thought I would provide a much more robust example, also in typescript, but it would be easy to convert to pure javascript. This function will query parents using either the ID like so "#my-element" or the class ".my-class" and unlike some of these answers will handle multiple classes. I found I named some similarly and so the examples above were finding the wrong things.

function queryParentElement(el:HTMLElement | null, selector:string) {
    let isIDSelector = selector.indexOf("#") === 0
    if (selector.indexOf('.') === 0 || selector.indexOf('#') === 0) {
        selector = selector.slice(1)
    }
    while (el) {
        if (isIDSelector) {
            if (el.id === selector) {
                return el
            }
        }
        else if (el.classList.contains(selector)) {
            return el;
        }
        el = el.parentElement;
    }
    return null;
}

To select by class name:

let elementByClassName = queryParentElement(someElement,".my-class")

To select by ID:

let elementByID = queryParentElement(someElement,"#my-element")

You can pass a regex to the spec command which will only run it blocks matching the name you supply.

spec path/to/my_spec.rb -e "should be the correct answer"

2019 Update: Rspec2 switched from the 'spec' command to the 'rspec' command.

This "tuple" feature it is called destructuring in EcmaScript2015 and is soon to be supported by up to date browsers. For the time being, only Firefox and Chrome support it.

But hey, you can use a transpiler.

The code would look as nice as python:

let tuple = ["Bob", 24]
let [name, age] = tuple

console.log(name)
console.log(age)

Try UISegmentedControl. It behaves similarly to radio buttons -- presents an array of choices and lets the user pick 1.

At this time, the only video codec that truly supports an alpha channel is VP8, which Flash uses. MP4 would probably support it if the video was exported as an image sequence, but I'm fairly certain Ogg video files have no support whatsoever for an alpha channel. This might be one of those rare instances where sticking with Flash would serve you better.

phpPgAdmin is PostgreSQL web frontend which is quite good.

If you are running Rails (its the default db in Rails) check the {RAILS_ROOT}/config/database.yml file and you will see something like:

database: db/development.sqlite3

This means that it will be in the {RAILS_ROOT}/db directory.

mysqli_error()

As in:

$sql = "Your SQL statement here";
$result = mysqli_query($conn, $sql) or trigger_error("Query Failed! SQL: $sql - Error: ".mysqli_error($conn), E_USER_ERROR);

Trigger error is better than die because you can use it for development AND production, it's the permanent solution.

netstat! That's a network command line utility which ships with windows. It shows all current established connections and all ports currently being listened to. You can use this program to check, but if you want to do this from code look into the System.Net.NetworkInformation namespace? It's a new namespace as of 2.0. There's some goodies there. But eventually if you wanna get the same kind of information that's available through the command netstat you'll need to result to P/Invoke...

Update: System.Net.NetworkInformation

That namespace contains a bunch of classes you can use for figuring out things about the network.

I wasn't able to find that old pice of code but I think you can write something similar yourself. A good start is to check out the IP Helper API. Google MSDN for the GetTcpTable WINAPI function and use P/Invoke to enumerate until you have the information you need.

Possible Solution

Swift provides distance() which measures the distance between start and end that can be used to create an NSRange:

let text = "Long paragraph saying something goes here!"
let textRange = text.startIndex..<text.endIndex
let attributedString = NSMutableAttributedString(string: text)

text.enumerateSubstringsInRange(textRange, options: NSStringEnumerationOptions.ByWords, { (substring, substringRange, enclosingRange, stop) -> () in
    let start = distance(text.startIndex, substringRange.startIndex)
    let length = distance(substringRange.startIndex, substringRange.endIndex)
    let range = NSMakeRange(start, length)

//    println("word: \(substring) - \(d1) to \(d2)")

        if (substring == "saying") {
            attributedString.addAttribute(NSForegroundColorAttributeName, value: NSColor.redColor(), range: range)
        }
})

VAL1 and VAL2 need to be dimmed as integer, not as string, to be used as an argument for Cells, which takes integers, not strings, as arguments.

Dim val1 As Integer, val2 As Integer, i As Integer

For i = 1 To 333

  Sheets("Feuil2").Activate
  ActiveSheet.Cells(i, 1).Select

    val1 = Cells(i, 1).Value
    val2 = Cells(i, 2).Value

Sheets("Classeur2.csv").Select
Cells(val1, val2).Select

ActiveCell.FormulaR1C1 = "1"

Next i

you could use something like this

def replace_all(text, dic):
  for i, j in dic.iteritems():
    text = text.replace(i, j)
  return text

This code is not my own and comes from here its a great article and dicusses in depth doing this

checked attribute is a boolean value so "checked" value of other "string" except boolean false converts to true.

Any string value will be true. Also presence of attribute make it true:

<input type="checkbox" checked>

You can make it uncheked only making boolean change in DOM using JS.

So the answer is: they are equal.

Well, this is a terribly late answer but I think I'll still put my two cents in... I could have posted this as a comment because this answer doesn't essentially add any new solution but it does add value to the post as yet another alternative. But in a comment I wouldn't be able to give all the details because of character limit.

NOTE: This needs an edit to bootstrap CSS file - move style definitions for .badge above .label-default. Couldn't find any practical side effects due to the change in my limited testing.

While broc.seib's solution is probably the best way to achieve the requirement of OP with minimal addition to CSS, it is possible to achieve the same effect without any extra CSS at all just like Jens A. Koch's solution or by using .label-xxx contextual classes because they are easy to remember compared to progress-bar-xxx classes. I don't think that .alert-xxx classes give the same effect.

All you have to do is just use .badge and .label-xxx classes together (but in this order). Don't forget to make the changes mentioned in NOTE above.

<a href="#">Inbox <span class="badge label-warning">42</span></a> looks like this:

IMPORTANT: This solution may break your styles if you decide to upgrade and forget to make the changes in your new local CSS file. My solution for this challenge was to copy all .label-xxx styles in my custom CSS file and load it after all other CSS files. This approach also helps when I use a CDN for loading BS3.

**P.S: ** Both the top rated answers have their pros and cons. It's just the way you prefer to do your CSS because there is no "only correct way" to do it.

You can also use translate(). If the third argument is too short, the corresponding characters from the second argument are deleted. Unlike regexp_replace() you don't need to worry about special characters. Source code.

Download Handle.

https://technet.microsoft.com/en-us/sysinternals/bb896655.aspx

If you want to find what program has a handle on a certain file, run this from the directory that Handle.exe is extracted to. Unless you've added Handle.exe to the PATH environment variable. And the file path is C:\path\path\file.txt", run this:

handle "C:\path\path\file.txt"

This will tell you what process(es) have the file (or folder) locked.

You can use stristr() or strpos(). Both return false if nothing is found.

I have to say I was quite surprised that HttpContext is null inside the constructor. I'm sure it's for performance reasons. Have confirmed that using IPrincipal as described below does get it injected into the constructor. Its essentially doing the same as the accepted answer, but in a more interfacey-way.

For anyone finding this question looking for an answer to the generic "How to get current user?" you can just access User directly from Controller.User. But you can only do this inside action methods (I assume because controllers don't only run with HttpContexts and for performance reasons).

However - if you need it in the constructor (as OP did) or need to create other injectable objects that need the current user then the below is a better approach:

Inject IPrincipal to get user

First meet IPrincipal and IIdentity

public interface IPrincipal
{
    IIdentity Identity { get; }
    bool IsInRole(string role);
}

public interface IIdentity
{
    string AuthenticationType { get; }
    bool IsAuthenticated { get; }
    string Name { get; }
}

IPrincipal and IIdentity represents the user and username. Wikipedia will comfort you if 'Principal' sounds odd.

Important to realize that whether you get it from IHttpContextAccessor.HttpContext.User, ControllerBase.User or ControllerBase.HttpContext.User you're getting an object that is guaranteed to be a ClaimsPrincipal object which implements IPrincipal.

There's no other type of User that ASP.NET uses for User right now, (but that's not to say other something else couldn't implement IPrincipal).

So if you have something which has a dependency of 'the current user name' that you want injected you should be injecting IPrincipal and definitely not IHttpContextAccessor.

Important: Don't waste time injecting IPrincipal directly to your controller, or action method - it's pointless since User is available to you there already.

In startup.cs:

   // Inject IPrincipal
   services.AddTransient<IPrincipal>(provider => provider.GetService<IHttpContextAccessor>().HttpContext.User);

Then in your DI object that needs the user you just inject IPrincipal to get the current user.

The most important thing here is if you're doing unit tests you don't need to send in an HttpContext, but only need to mock something that represents IPrincipal which can just be ClaimsPrincipal.

One extra important thing that I'm not 100% sure about. If you need to access the actual claims from ClaimsPrincipal you need to cast IPrincipal to ClaimsPrincipal. This is fine since we know 100% that at runtime it's of that type (since that's what HttpContext.User is). I actually like to just do this in the constructor since I already know for sure any IPrincipal will be a ClaimsPrincipal.

If you're doing mocking, just create a ClaimsPrincipal directly and pass it to whatever takes IPrincipal.

Exactly why there is no interface for IClaimsPrincipal I'm not sure. I assume MS decided that ClaimsPrincipal was just a specialized 'collection' that didn't warrant an interface.

From my HomeController I want to call this Method and convert Json response to List

No you don't. You really don't want to add the overhead of an HTTP call and (de)serialization when the code is within reach. It's even in the same assembly!

Your ApiController goes against (my preferred) convention anyway. Let it return a concrete type:

public IEnumerable<QDocumentRecord> GetAllRecords()
{
    listOfFiles = ...
    return listOfFiles;
}

If you don't want that and you're absolutely sure you need to return HttpResponseMessage, then still there's absolutely no need to bother with calling JsonConvert.SerializeObject() yourself:

return Request.CreateResponse<List<QDocumentRecord>>(HttpStatusCode.OK, listOfFiles);

Then again, you don't want business logic in a controller, so you extract that into a class that does the work for you:

public class FileListGetter
{
    public IEnumerable<QDocumentRecord> GetAllRecords()
    {
        listOfFiles = ...
        return listOfFiles;
    }
}

Either way, then you can call this class or the ApiController directly from your MVC controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        var listOfFiles = new DocumentsController().GetAllRecords();
        // OR
        var listOfFiles = new FileListGetter().GetAllRecords();

        return View(listOfFiles);
    }
}

But if you really, really must do an HTTP request, you can use HttpWebRequest, WebClient, HttpClient or RestSharp, for all of which plenty of tutorials exist.

You can try this

<a [attr.disabled]="someCondition ? true: null"></a>

If you just want to kill any/all java processes, then all you need is;

killall java

If, however, you want to kill the wskInterface process in particular, then you're most of the way there, you just need to strip out the process id;

PID=`ps -ef | grep wskInterface | awk '{ print $2 }'`
kill -9 $PID

Should do it, there is probably an easier way though...

• Download the acrobat reader .apk file for android to display pdf file
• Put your pdf files on an sd card

• Use the snippet of code below

  File file= new File("/sdcard/test.pdf");
  Uri path=Uri.fromFile(file);
  Intent i =new Intent(Intent.ACTION_VIEW);
  i.setDataAndType(path,"application/pdf");
  i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
  startActivity(i);
  

For example, here's a table that has a primary key but is not AUTO_INCREMENT:

mysql> CREATE TABLE foo (
  id INT NOT NULL,
  PRIMARY KEY (id)
);
mysql> INSERT INTO foo VALUES (1), (2), (5);

You can MODIFY the column to redefine it with the AUTO_INCREMENT option:

mysql> ALTER TABLE foo MODIFY COLUMN id INT NOT NULL AUTO_INCREMENT;

Verify this has taken effect:

mysql> SHOW CREATE TABLE foo;

Outputs:

CREATE TABLE foo (
  `id` INT(11) NOT NULL AUTO_INCREMENT,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=6 DEFAULT CHARSET=latin1

Note that you have modified the column definition in place, without requiring creating a second column and dropping the original column. The PRIMARY KEY constraint is unaffected, and you don't need to mention in in the ALTER TABLE statement.

Next you can test that an insert generates a new value:

mysql> INSERT INTO foo () VALUES (); -- yes this is legal syntax
mysql> SELECT * FROM foo;

Outputs:

+----+
| id |
+----+
|  1 | 
|  2 | 
|  5 | 
|  6 | 
+----+
4 rows in set (0.00 sec)

I tested this on MySQL 5.0.51 on Mac OS X.

I also tested with ENGINE=InnoDB and a dependent table. Modifying the id column definition does not interrupt referential integrity.

To respond to the error 150 you mentioned in your comment, it's probably a conflict with the foreign key constraints. My apologies, after I tested it I thought it would work. Here are a couple of links that may help to diagnose the problem:

• What does mysql error 1025 (HY000): Error on rename of './foo' (errorno: 150) mean?
• http://www.simplicidade.org/notes/archives/2008/03/mysql_errno_150.html

You should set the src attribute after the onload event, f.ex:

el.onload = function() { //...
el.src = script;

You should also append the script to the DOM before attaching the onload event:

$body.append(el);
el.onload = function() { //...
el.src = script;

Remember that you need to check readystate for IE support. If you are using jQuery, you can also try the getScript() method: http://api.jquery.com/jQuery.getScript/

First, we choose stable (not static) data columns to form a Primary Key, precisely because updating Keys in a Relational database (in which the references are by Key) is something we wish to avoid.

1. For this issue, it doesn't matter if the Key is a Relational Key ("made up from the data"), and thus has Relational Integrity, Power, and Speed, or if the "key" is a Record ID, with none of that Relational Integrity, Power, and Speed. The effect is the same.

2. I state this because there are many posts by the clueless ones, who suggest that this is the exact reason that Record IDs are somehow better than Relational Keys.

3. The point is, the Key or Record ID is migrated to wherever a reference is required.

Second, if you have to change the value of the Key or Record ID, well, you have to change it. Here is the OLTP Standard-compliant method. Note that the high-end vendors do not allow "cascade update".

• Write a proc. Foo_UpdateCascade_tr @ID, where Foo is the table name

• Begin a Transaction

• First INSERT-SELECT a new row in the parent table, from the old row, with the new Key or RID value

• Second, for all child tables, working top to bottom, INSERT-SELECT the new rows, from the old rows, with the new Key or RID value

• Third, DELETE the rows in the child tables that have the old Key or RID value, working bottom to top

• Last, DELETE the row in the parent table that has the old Key or RID value

• Commit the Transaction

Re the Other Answers

The other answers are incorrect.

• Disabling constraints and then enabling them, after UPDATing the required rows (parent plus all children) is not something that a person would do in an online production environment, if they wish to remain employed. That advice is good for single-user databases.

• The need to change the value of a Key or RID is not indicative of a design flaw. It is an ordinary need. That is mitigated by choosing stable (not static) Keys. It can be mitigated, but it cannot be eliminated.

• A surrogate substituting a natural Key, will not make any difference. In the example you have given, the "key" is a surrogate. And it needs to be updated.

  • Please, just surrogate, there is no such thing as a "surrogate key", because each word contradicts the other. Either it is a Key (made up from the data) xor it isn't. A surrogate is not made up from the data, it is explicitly non-data. It has none of the properties of a Key.

• There is nothing "tricky" about cascading all the required changes. Refer to the steps given above.

• There is nothing that can be prevented re the universe changing. It changes. Deal with it. And since the database is a collection of facts about the universe, when the universe changes, the database will have to change. That is life in the big city, it is not for new players.

• People getting married and hedgehogs getting buried are not a problem (despite such examples being used to suggest that it is a problem). Because we do not use Names as Keys. We use small, stable Identifiers, such as are used to Identify the data in the universe.

  • Names, descriptions, etc, exist once, in one row. Keys exist wherever they have been migrated. And if the "key" is a RID, then the RID too, exists wherever it has been migrated.

• Don't update the PK! is the second-most hilarious thing I have read in a while. Add a new column is the most.

Here's a variant that uses fancy indexing and has the actual values as an intermediate:

p31 = numpy.asarray(o31)
values = p31[p31<200]
za = len(values)

try giving border in % for exapmle 0.1% according to your need.

You can use trunc and to_date as follows:

select TO_CHAR (g.FECHA, 'DD-MM-YYYY HH24:MI:SS') fecha_salida, g.NUMERO_GUIA, g.BOD_ORIGEN, g.TIPO_GUIA, dg.DOC_NUMERO, dg.* 
from ils_det_guia dg, ils_guia g
where dg.NUMERO_GUIA = g.NUMERO_GUIA and dg.TIPO_GUIA = g.TIPO_GUIA and dg.BOD_ORIGEN = g.BOD_ORIGEN
and dg.LAB_CODIGO = 56 
and trunc(g.FECHA) > to_date('01/02/15','DD/MM/YY')
order by g.FECHA;

I've used mingw on Linux to make Windows executables in C, I suspect C++ would work as well.

I have a project, ELLCC, that packages clang and other things as a cross compiler tool chain. I use it to compile clang (C++), binutils, and GDB for Windows. Follow the download link at ellcc.org for pre-compiled binaries for several Linux hosts.

There's a third way that doesn't require a converter or a change to your view model: use a style:

<Style TargetType="Button">
   <Setter Property="Visibility" Value="Collapsed"/>
   <Style.Triggers>
      <DataTrigger Binding="{Binding IsVisible}" Value="True">
         <Setter Property="Visibility" Value="Visible"/>
      </DataTrigger>
   </Style.Triggers>
</Style>

I tend to prefer this technique because I use it in a lot of cases where what I'm binding to is not boolean - e.g. displaying an element only if its DataContext is not null, or implementing multi-state displays where different layouts appear based on the setting of an enum in the view model.

I would like to add that Using the library momentjs in javascript you can have the whole data information in an object with:

const today = moment(1557697070824.94).toObject();

You should obtain an object with this properties:

today: {
  date: 15,
  hours: 2,
  milliseconds: 207,
  minutes: 31,
  months: 4
  seconds: 22,
  years: 2019
}

It is very useful when you have to calculate dates.

getFilesDir()

Returns the absolute path to the directory on the filesystem where files created with openFileOutput(String, int) are stored.

Environment.getDataDirectory()

Return the user data directory.

There is no need to add any extra div wrapper as others suggest.

The simplest way is to wrap your input element inside a related label tag and set input style to display:block.

Bonus point earned: now you don't need to set the labels for attribute. Because every label target the nested input.

<form name="message" method="post">
    <section>
        <label class="left">
            Name
            <input id="name" type="text" name="name">
        </label>
        <label class="right">
            Email
            <input id="email" type="text" name="email">
        </label>
    </section>

Short and elegant

#include <vector>
#include <string>
using namespace std;

vector<string> split(string data, string token)
{
    vector<string> output;
    size_t pos = string::npos; // size_t to avoid improbable overflow
    do
    {
        pos = data.find(token);
        output.push_back(data.substr(0, pos));
        if (string::npos != pos)
            data = data.substr(pos + token.size());
    } while (string::npos != pos);
    return output;
}

can use any string as delimiter, also can be used with binary data (std::string supports binary data, including nulls)

using:

auto a = split("this!!is!!!example!string", "!!");

output:

This is for Mac users:

first of all you have to clarify where the class file is... so for example, in 'Terminal' (A Mac Application) you would type:

cd

then wherever you file is e.g:

cd /Users/CollarBlast/Desktop/JavaFiles/

then you would hit enter. After that you would do the command. e.g:

cd /Users/CollarBlast/Desktop/JavaFiles/ (then i would press enter...)

Then i would type the command:

javap -c JavaTestClassFile.class (then i would press enter again...)

and hopefully it should work!

radian can also be converted to degree by using numpy

print(np.rad2deg(1))
57.29577951308232

if needed to roundoff ( I did with 6 digits after decimal below), then

print(np.round(np.rad2deg(1), 6)

57.29578

This is a way to see if any XML-files exists in that folder, yes.

To check for specific files use File.Exists(path), which will return a boolean indicating wheter the file at path exists.

Adding only android-support-v7-appcompat.jar to library dependencies is not enough, you have also to import in your project the module that you can find in your SDK at the path \android-sdk\extras\android\support\v7\appcompatand after that add module dependencies configuring the project structure in this way

otherwise are included only the class files of support library and the app is not able to load the other resources causing the error.

In addition as reVerse suggested replace this

public CustomActionBarDrawerToggle(Activity mActivity,
                                           DrawerLayout mDrawerLayout) {
            super(mActivity, mDrawerLayout,new Toolbar(MyActivity.this) ,
                    R.string.ns_menu_open, R.string.ns_menu_close);
        }

with

public CustomActionBarDrawerToggle(Activity mActivity,
                                           DrawerLayout mDrawerLayout) {
            super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);
        }

I'm sure Scott's solution worked at one point,

But it's a good argument for not using reflection to peek at private apis. It's broken now.

I was able to set out parameters using a delegate

      delegate void MockOutDelegate(string s, out int value);

    public void SomeMethod()
    {
        ....

         int value;
         myMock.Setup(x => x.TryDoSomething(It.IsAny<string>(), out value))
            .Callback(new MockOutDelegate((string s, out int output) => output = userId))
            .Returns(true);
    }

The docs indicate that numpy.correlate is not what you are looking for:

numpy.correlate(a, v, mode='valid', old_behavior=False)[source]
  Cross-correlation of two 1-dimensional sequences.
  This function computes the correlation as generally defined in signal processing texts:
     z[k] = sum_n a[n] * conj(v[n+k])
  with a and v sequences being zero-padded where necessary and conj being the conjugate.

Instead, as the other comments suggested, you are looking for a Pearson correlation coefficient. To do this with scipy try:

from scipy.stats.stats import pearsonr   
a = [1,4,6]
b = [1,2,3]   
print pearsonr(a,b)

This gives

(0.99339926779878274, 0.073186395040328034)

You can also use numpy.corrcoef:

import numpy
print numpy.corrcoef(a,b)

This gives:

[[ 1.          0.99339927]
 [ 0.99339927  1.        ]]

My approach:

<div class="left">Left</div>
<div class="right">Right</div>

CSS:

.left {
    float: left;
    width: calc(100% - 200px);
    background: green;
}

.right {
    float: right;
    width: 200px;
    background: yellow;
}

You need to use @Autowired and @Value. Refer this post for more information on this topic.

Also worth noting is that with update_attribute, the desired attribute to be updated doesn't need to be white listed with attr_accessible to update it as opposed to the mass assignment method update_attributes which will only update attr_accessible specified attributes.

Try this formula:

=SUBSTITUTE(TEXT(A1/B1,"?/?"),"/",":")

Result:

A   B   C
33  11  3:1
25  5   5:1
6   4   3:2

Explanation:

• TEXT(A1/B1,"?/?") turns A/B into an improper fraction
• SUBSTITUTE(...) replaces the "/" in the fraction with a colon

This doesn't require any special toolkits or macros. The only downside might be that the result is considered text--not a number--so you can easily use it for further calculations.

Note: as @Robin Day suggested, increase the number of question marks (?) as desired to reduce rounding (thanks Robin!).

Please don't use any library for this effect instead use the recommended way of doing it according to Google I/O. In your recyclerView's onBindViewHolder method do this:

final boolean isExpanded = position==mExpandedPosition;
holder.details.setVisibility(isExpanded?View.VISIBLE:View.GONE);
holder.itemView.setActivated(isExpanded);
holder.itemView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        mExpandedPosition = isExpanded ? -1:position;
        TransitionManager.beginDelayedTransition(recyclerView);
        notifyDataSetChanged();
    }
});

• Where details is my view that will be displayed on touch (call details in your case. Default Visibility.GONE).
• mExpandedPosition is an int variable initialized to -1

And for the cool effects that you wanted, use these as your list_item attributes:

android:background="@drawable/comment_background"
android:stateListAnimator="@animator/comment_selection"

where comment_background is:

<selector
xmlns:android="http://schemas.android.com/apk/res/android"
android:constantSize="true"
android:enterFadeDuration="@android:integer/config_shortAnimTime"
android:exitFadeDuration="@android:integer/config_shortAnimTime">

<item android:state_activated="true" android:drawable="@color/selected_comment_background" />
<item android:drawable="@color/comment_background" />
</selector>

and comment_selection is:

<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:state_activated="true">
    <objectAnimator
        android:propertyName="translationZ"
        android:valueTo="@dimen/z_card"
        android:duration="2000"
        android:interpolator="@android:interpolator/fast_out_slow_in" />
</item>

<item>
    <objectAnimator
        android:propertyName="translationZ"
        android:valueTo="0dp"
        android:duration="2000"

</item>
</selector>

if you want to print ascii characters based on their ascii code and do not want to go beyond that (like unicode characters), you can define your variable as a byte, and then use the (char) convert. i.e.:

public static void main(String[] args) {
    byte b = 65;
    for (byte i=b; i<=b+25; i++) {
        System.out.print((char)i + ", ");
    }

BTW, the ascii code for the letter 'A' is 65

Unless I am misunderstanding what you are asking you can do this on the properties for your data grid view. You need to set the Anchor property to the sides you want it locked to.

An empty border is transparent. You need to specify a Line Border or some other visible border when you set the border in order to see it.

Based on Edit to question:

The painting does not honor the border. Add this line of code to your test and you will see the border:

    jboard.setBorder(BorderFactory.createEmptyBorder(0,10,10,10)); 
    jboard.add(new JButton("Test"));  //Add this line
    frame.add(jboard);

  var table = Tables[0]; //get first table from Dataset
  foreach (DataRow row in table.Rows)
     {
       foreach (var item in row.ItemArray)
         {
            console.Write("Value:"+item);
         }
     }

Do this:

<div id="sampleDiv">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</div>

#sampleDiv{

Not sure about solutions but a temporary workaround is to ask eslint to ignore it by adding the following on top of the problem line.

If I understand you right, you can do this:

<img src="image.png" style="background-color:red;" />

In fact, you can even apply a whole background-image to the image, resulting in two "layers" without the need for multi-background support in the browser ;)

Please be aware that the accepted answer is a bit incomplete. Yes, at the most basic level Collation handles sorting. BUT, the comparison rules defined by the chosen Collation are used in many places outside of user queries against user data.

If "What does COLLATE SQL_Latin1_General_CP1_CI_AS do?" means "What does the COLLATE clause of CREATE DATABASE do?", then:

The COLLATE {collation_name} clause of the CREATE DATABASE statement specifies the default Collation of the Database, and not the Server; Database-level and Server-level default Collations control different things.

Server (i.e. Instance)-level controls:

• Database-level Collation for system Databases: master, model, msdb, and tempdb.
• Due to controlling the DB-level Collation of tempdb, it is then the default Collation for string columns in temporary tables (global and local), but not table variables.
• Due to controlling the DB-level Collation of master, it is then the Collation used for Server-level data, such as Database names (i.e. name column in sys.databases), Login names, etc.
• Handling of parameter / variable names
• Handling of cursor names
• Handling of GOTO labels
• Default Collation used for newly created Databases when the COLLATE clause is missing

Database-level controls:

• Default Collation used for newly created string columns (CHAR, VARCHAR, NCHAR, NVARCHAR, TEXT, and NTEXT -- but don't use TEXT or NTEXT) when the COLLATE clause is missing from the column definition. This goes for both CREATE TABLE and ALTER TABLE ... ADD statements.
• Default Collation used for string literals (i.e. 'some text') and string variables (i.e. @StringVariable). This Collation is only ever used when comparing strings and variables to other strings and variables. When comparing strings / variables to columns, then the Collation of the column will be used.
• The Collation used for Database-level meta-data, such as object names (i.e. sys.objects), column names (i.e. sys.columns), index names (i.e. sys.indexes), etc.
• The Collation used for Database-level objects: tables, columns, indexes, etc.

Also:

• ASCII is an encoding which is 8-bit (for common usage; technically "ASCII" is 7-bit with character values 0 - 127, and "ASCII Extended" is 8-bit with character values 0 - 255). This group is the same across cultures.
• The Code Page is the "extended" part of Extended ASCII, and controls which characters are used for values 128 - 255. This group varies between each culture.
• Latin1 does not mean "ASCII" since standard ASCII only covers values 0 - 127, and all code pages (that can be represented in SQL Server, and even NVARCHAR) map those same 128 values to the same characters.

If "What does COLLATE SQL_Latin1_General_CP1_CI_AS do?" means "What does this particular collation do?", then:

• Because the name start with SQL_, this is a SQL Server collation, not a Windows collation. These are definitely obsolete, even if not officially deprecated, and are mainly for pre-SQL Server 2000 compatibility. Although, quite unfortunately SQL_Latin1_General_CP1_CI_AS is very common due to it being the default when installing on an OS using US English as its language. These collations should be avoided if at all possible.

  Windows collations (those with names not starting with SQL_) are newer, more functional, have consistent sorting between VARCHAR and NVARCHAR for the same values, and are being updated with additional / corrected sort weights and uppercase/lowercase mappings. These collations also don't have the potential performance problem that the SQL Server collations have: Impact on Indexes When Mixing VARCHAR and NVARCHAR Types.

• Latin1_General is the culture / locale.
  • For NCHAR, NVARCHAR, and NTEXT data this determines the linguistic rules used for sorting and comparison.
  • For CHAR, VARCHAR, and TEXT data (columns, literals, and variables) this determines the:
    • linguistic rules used for sorting and comparison.
    • code page used to encode the characters. For example, Latin1_General collations use code page 1252, Hebrew collations use code page 1255, and so on.

• CP{code_page} or {version}

  • For SQL Server collations: CP{code_page}, is the 8-bit code page that determines what characters map to values 128 - 255. While there are four code pages for Double-Byte Character Sets (DBCS) that can use 2-byte combinations to create more than 256 characters, these are not available for the SQL Server collations.

  • For Windows collations: {version}, while not present in all collation names, refers to the SQL Server version in which the collation was introduced (for the most part). Windows collations with no version number in the name are version 80 (meaning SQL Server 2000 as that is version 8.0). Not all versions of SQL Server come with new collations, so there are gaps in the version numbers. There are some that are 90 (for SQL Server 2005, which is version 9.0), most are 100 (for SQL Server 2008, version 10.0), and a small set has 140 (for SQL Server 2017, version 14.0).

    I said "for the most part" because the collations ending in _SC were introduced in SQL Server 2012 (version 11.0), but the underlying data wasn't new, they merely added support for supplementary characters for the built-in functions. So, those endings exist for version 90 and 100 collations, but only starting in SQL Server 2012.

• Next you have the sensitivities, that can be in any combination of the following, but always specified in this order:
  • CS = case-sensitive or CI = case-insensitive
  • AS = accent-sensitive or AI = accent-insensitive
  • KS = Kana type-sensitive or missing = Kana type-insensitive
  • WS = width-sensitive or missing = width insensitive
  • VSS = variation selector sensitive (only available in the version 140 collations) or missing = variation selector insensitive

• Optional last piece:

  • _SC at the end means "Supplementary Character support". The "support" only affects how the built-in functions interpret surrogate pairs (which are how supplementary characters are encoded in UTF-16). Without _SC at the end (or _140_ in the middle), built-in functions don't see a single supplementary character, but instead see two meaningless code points that make up the surrogate pair. This ending can be added to any non-binary, version 90 or 100 collation.
  • _BIN or _BIN2 at the end means "binary" sorting and comparison. Data is still stored the same, but there are no linguistic rules. This ending is never combined with any of the 5 sensitivities or _SC. _BIN is the older style, and _BIN2 is the newer, more accurate style. If using SQL Server 2005 or newer, use _BIN2. For details on the differences between _BIN and _BIN2, please see: Differences Between the Various Binary Collations (Cultures, Versions, and BIN vs BIN2).

  • _UTF8 is a new option as of SQL Server 2019. It's an 8-bit encoding that allows for Unicode data to be stored in VARCHAR and CHAR datatypes (but not the deprecated TEXT datatype). This option can only be used on collations that support supplementary characters (i.e. version 90 or 100 collations with _SC in their name, and version 140 collations). There is also a single binary _UTF8 collation (_BIN2, not _BIN).

    PLEASE NOTE: UTF-8 was designed / created for compatibility with environments / code that are set up for 8-bit encodings yet want to support Unicode. Even though there are a few scenarios where UTF-8 can provide up to 50% space savings as compared to NVARCHAR, that is a side-effect and has a cost of a slight hit to performance in many / most operations. If you need this for compatibility, then the cost is acceptable. If you want this for space-savings, you had better test, and TEST AGAIN. Testing includes all functionality, and more than just a few rows of data. Be warned that UTF-8 collations work best when ALL columns, and the database itself, are using VARCHAR data (columns, variables, string literals) with a _UTF8 collation. This is the natural state for anyone using this for compatibility, but not for those hoping to use it for space-savings. Be careful when mixing VARCHAR data using a _UTF8 collation with either VARCHAR data using non-_UTF8 collations or NVARCHAR data, as you might experience odd behavior / data loss. For more details on the new UTF-8 collations, please see: Native UTF-8 Support in SQL Server 2019: Savior or False Prophet?

Okay so it goes like this:

You have created a virtual environment and django module belongs to that environment only.Since virtualenv isolates itself from everything else,hence you are seeing this.

go through this for further assistance:

http://www.swegler.com/becky/blog/2011/08/27/python-django-mysql-on-windows-7-part-i-getting-started/

1.You can switch to the directory where your virtual environment is stored and then run the django module.

2.Alternatively you can install django globally to your python->site-packages by either running pip or easy_install

Command using pip: pip install django

then do this:

import django print (django.get_version()) (depending on which version of python you use.This for python 3+ series)

and then you can run this: python manage.py runserver and check on your web browser by typing :localhost:8000 and you should see django powered page.

Hope this helps.

As the used variables from outside the lamda have to be (implicitly) final, you have to use something like AtomicInteger or write your own data structure.

See https://docs.oracle.com/javase/tutorial/java/javaOO/lambdaexpressions.html#accessing-local-variables.

Trigger the submit event on the DOM Node, not a jQuery Object.

$('#subscription_order_form')[0].submit();

or

$('#subscription_order_form').get(0).submit();

or

document.getElementById("subscription_order_form").submit();

This bypasses the jQuery bound event allowing the form to submit normally.

Send AJAX Http Requests to the server periodically (say once for every 60 seconds) through javascript to maintain session with the server until the file upload gets completed.

Yes, it is possible to merge .NET executables with libraries. There are multiple tools available to get the job done:

• ILMerge is a utility that can be used to merge multiple .NET assemblies into a single assembly.
• Mono mkbundle, packages an exe and all assemblies with libmono into a single binary package.
• IL-Repack is a FLOSS alterantive to ILMerge, with some additional features.

In addition this can be combined with the Mono Linker, which does remove unused code and therefor makes the resulting assembly smaller.

Another possibility is to use .NETZ, which does not only allow compressing of an assembly, but also can pack the dlls straight into the exe. The difference to the above mentioned solutions is that .NETZ does not merge them, they stay separate assemblies but are packed into one package.

.NETZ is a open source tool that compresses and packs the Microsoft .NET Framework executable (EXE, DLL) files in order to make them smaller.

@Override
public void onStart() {
    super.onStart();
    Dialog dialog = getDialog();
    if (dialog != null)
    {
        dialog.getWindow().setLayout(-1, -2);
        dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation;
        Window window = getDialog().getWindow();
        WindowManager.LayoutParams params = window.getAttributes();
        params.dimAmount = 1.0f;
        window.setAttributes(params);
        window.setBackgroundDrawableResource(android.R.color.transparent);
    }
}

Use Shift+Del.

More info: Shift+Del combination key set a field to null when you filled a field by a value and you changed your decision and you want to make it null. It is useful and I amazed from the other answers that give strange solutions.

The capitalization is wrong, and you have an extra argument.

Do this instead:

$('img#thumb').removeAttr('id');

For future reference, there aren't any jQuery methods that begin with a capital letter. They all take the same form as this one, starting with a lower case, and the first letter of each joined "word" is upper case.

There's no need for the outer try in your example, so you can at least go down from 3 to 2, and also you don't need closing ; at the end of the resource list. The advantage of using two try blocks is that all of your code is present up front so you don't have to refer to a separate method:

public List<User> getUser(int userId) {
    String sql = "SELECT id, username FROM users WHERE id = ?";
    List<User> users = new ArrayList<>();
    try (Connection con = DriverManager.getConnection(myConnectionURL);
         PreparedStatement ps = con.prepareStatement(sql)) {
        ps.setInt(1, userId);
        try (ResultSet rs = ps.executeQuery()) {
            while(rs.next()) {
                users.add(new User(rs.getInt("id"), rs.getString("name")));
            }
        }
    } catch (SQLException e) {
        e.printStackTrace();
    }
    return users;
}

SELECT TOP 2 [Id] FROM table

I personally prefer to just get them in one object hash, then I can access them anywhere. This could easily be set to an injectable variable and then everything could have it and it only grabbed once.

By wrapping the function this can also be done as a one liner.

var meta = (function () {
    var m = document.querySelectorAll("meta"), r = {};
    for (var i = 0; i < m.length; i += 1) {
        r[m[i].getAttribute("name")] = m[i].getAttribute("content")
    }
    return r;
})();

You can use Interpolation:

<img src={{imagePath}} />

Or you can use a template expression:

<img [src]="imagePath" />

In a ngFor loop it might look like this:

If you updated Internet Explorer and began having technical problems, you can use the Compatibility View feature to emulate a previous version of Internet Explorer.

For instructions, see the section below that corresponds with your version. To find your version number, click Help > About Internet Explorer. Internet Explorer 11

To edit the Compatibility View list:

Open the desktop, and then tap or click the Internet Explorer icon on the taskbar.
Tap or click the Tools button (Image), and then tap or click Compatibility View settings.
To remove a website:
Click the website(s) where you would like to turn off Compatibility View, clicking Remove after each one.
To add a website:
Under Add this website, enter the website(s) where you would like to turn on Compatibility View, clicking Add after each one.

If you set the image in div, you also must set both height and width. This may cause the image to lose its proportion. In addition, you must set the image URL in CSS instead of HTML.

Instead, you can set the image using the IMG tag. In the container class you can only set the width in percent or pixel and the height will automatically maintain proportion.

This is also more effective for accessibility of search engines and reading engines to define an image using an IMG tag.

Another simple example:

Search: style="(.+?)"
Replace: css={css`$1`}

Useful for converting HTML to JSX with emotion/css!

For those strictly looking for a solution that works for input or textarea, this is the simplest solution I've came across. Only a few lines of CSS and one line of JS.

The JavaScript sets a data-* attribute on the element equal to the value of the input. The input is set within a CSS grid, where that grid is a pseudo-element that uses that data-* attribute as its content. That content is what stretches the grid to the appropriate size based on the input value.

I like to beat dead horses, but I just wanted to make an additional point:

First of all, the problem is that not all conditions of your control structure have been addressed. Essentially, you're saying if a, then this, else if b, then this. End. But what if neither? There's no way to exit (i.e. not every 'path' returns a value).

My additional point is that this is an example of why you should aim for a single exit if possible. In this example you would do something like this:

bool result = false;
if(conditionA)
{
   DoThings();
   result = true;
}
else if(conditionB)
{
   result = false;
}
else if(conditionC)
{
   DoThings();
   result = true;
}

return result;

So here, you will always have a return statement and the method always exits in one place. A couple things to consider though... you need to make sure that your exit value is valid on every path or at least acceptable. For example, this decision structure only accounts for three possibilities but the single exit can also act as your final else statement. Or does it? You need to make sure that the final return value is valid on all paths. This is a much better way to approach it versus having 50 million exit points.

This should give you the conversion dp to pixels:

public static int dpToPx(int dp)
{
    return (int) (dp * Resources.getSystem().getDisplayMetrics().density);
}

This should give you the conversion pixels to dp:

public static int pxToDp(int px)
{
    return (int) (px / Resources.getSystem().getDisplayMetrics().density);
}

How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:

Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.

h1 and h2 are native display: block elements.

Make them display: inline so they behave like normal text.

You should also reset the default padding and margin that the elements have.

After several attempts and going deep in Tomcat's source code I found out that the simple property useNaming="false" did the trick!! Now Tomcat resolves names java:/liferay instead of java:comp/env/liferay

Based on @ofer.sheffer answer, this is the CMD variant for adding an affix (this is not the question, but this page is still the #1 google result if you search affix). It is a bit different because of the extension.

for %a in (*.*) do ren "%~a" "%~na-affix%~xa"

You can change the "-affix" part.

If you're using Python 3, you can you use the star before a variable (on the left side of an assignment) to have it be a list in unpacking.

# Example 1: a is 1 and b is [2, 3]

a, *b = [1, 2, 3]

# Example 2: a is 1, b is [2, 3], and c is 4

a, *b, c = [1, 2, 3, 4]

# Example 3: b is [1, 2] and c is 3

*b, c = [1, 2, 3]       

# Example 4: a is 1 and b is []

a, *b = [1]

Converting your value in milliseconds to days is simply (MsValue / 86,400,000)

We can get 1/1/1970 as numeric value by DATE(1970,1,1)

= (MsValueCellReference / 86400000) + DATE(1970,1,1)

Using your value of 1271664970687 and formatting it as dd/mm/yyyy hh:mm:ss gives me a date and time of 19/04/2010 08:16:11

Python is white-space sensitive in regard to the indentation. Once the indentation level falls back to the level at which the function is defined, the function has ended.

You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:

  /**
   * Used to stitch together functional operators into a chain.
   * @method pipe
   * @return {Observable} the Observable result of all of the operators having
   * been called in the order they were passed in.
   *
   * @example
   *
   * import { map, filter, scan } from 'rxjs/operators';
   *
   * Rx.Observable.interval(1000)
   *   .pipe(
   *     filter(x => x % 2 === 0),
   *     map(x => x + x),
   *     scan((acc, x) => acc + x)
   *   )
   *   .subscribe(x => console.log(x))
   */

In brief:

Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan(), but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe() to make a chain of those operators (see example above).

Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do(). You can think of it as if observable was an array over time, then tap() would be an equivalent to Array.forEach().

If you want to compare dates and not time, you could use this:

$d1->format("Y-m-d") == $d2->format("Y-m-d")

Here are the steps that worked for me:

1. Enable Directions API; Geocoding API; Gelocation API console.cloud.google.com/google/maps-apis

The guide you linked now has a Tear Down section:

Talking to the master with the appropriate credentials, run:

kubectl drain <node name> --delete-local-data --force --ignore-daemonsets
kubectl delete node <node name>

Then, on the node being removed, reset all kubeadm installed state:

kubeadm reset

The difference lies in the fact that ./gradlew indicates you are using a gradle wrapper. The wrapper is generally part of a project and it facilitates installation of gradle. If you were using gradle without the wrapper you would have to manually install it - for example, on a mac brew install gradle and then invoke gradle using the gradle command. In both cases you are using gradle, but the former is more convenient and ensures version consistency across different machines.

Each Wrapper is tied to a specific version of Gradle, so when you first run one of the commands above for a given Gradle version, it will download the corresponding Gradle distribution and use it to execute the build.

Not only does this mean that you don’t have to manually install Gradle yourself, but you are also sure to use the version of Gradle that the build is designed for. This makes your historical builds more reliable

Also, Udacity has a neat, high level video explaining the concept of the gradle wrapper - https://www.youtube.com/watch?v=1aA949H-shk

In spring3.2, new solution is introduced by: http://static.springsource.org/spring/docs/3.2.0.BUILD-SNAPSHOT/api/org/springframework/http/converter/json/Jackson2ObjectMapperFactoryBean.html , the below is my example:

 <mvc:annotation-driven>
   ?<mvc:message-converters>
     ??<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
       ???<property name="objectMapper">
         ????<bean
 class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
           ?????<property name="featuresToEnable">
             ??????<array>
               ???????<util:constant static-field="com.fasterxml.jackson.core.JsonParser.Feature.ALLOW_SINGLE_QUOTES" />
             ??????</array>
           ?????</property>
         ????</bean>
       ???</property>
     ??</bean>
   ?</mvc:message-converters>
 </mvc:annotation-driven>

Go to the terminal and regenerate the ssh key again. Type ssh-keygen. It will ask you where you want to save it, type the path.

Then copy the public key to gitlabs platform. It usually starts with ssh-rsa.

You may consider using CRON for that kind of operation. Sending mass mail at once is certainly not good, it may be detected as spam, ddos, crash your server etc.

So CRON could be a great solution, send 100 mails at once, then wait a few minutes, next 100, etc.

You should not use space character while naming database objects. Even though it's possible by using double quotes(quoted identifiers), CREATE TABLE "chartered flight" ..., it's not recommended. Take a closer look here

If you know that you want the values to the thousandths, place, it's

SELECT (num - FLOOR(num)) * 1000 FROM table...;

Actually, I researched this question and consider all situations. because it is a big issue on my project too. So I reach the below function, it works for all versions of all browsers on all devices:

const isTouchDevice = () => {
  const prefixes = ['', '-webkit-', '-moz-', '-o-', '-ms-', ''];
  const mq = query => window.matchMedia(query).matches;

  if (
    'ontouchstart' in window ||
    (window.DocumentTouch && document instanceof DocumentTouch)
  ) {
    return true;
  }
  return mq(['(', prefixes.join('touch-enabled),('), 'heartz', ')'].join(''));
};

Hint: Definitely, the isTouchDevice just returns boolean values.

Sometimes problems in your project build path can cause this, make sure you resolve it first, in my case the prolem was :

And when fix it highlights come back.

I need to decrypt a password. The password is crypted with password_hash function.

$password = 'examplepassword';
$crypted = password_hash($password, PASSWORD_DEFAULT);

Its not clear to me if you need password_verify, or you are trying to gain unauthorized access to the application or database. Other have talked about password_verify, so here's how you could gain unauthorized access. Its what bad guys often do when they try to gain access to a system.

First, create a list of plain text passwords. A plain text list can be found in a number of places due to the massive data breaches from companies like Adobe. Sort the list and then take the top 10,000 or 100,000 or so.

Second, create a list of digested passwords. Simply encrypt or hash the password. Based on your code above, it does not look like a salt is being used (or its a fixed salt). This makes the attack very easy.

Third, for each digested password in the list, perform a select in an attempt to find a user who is using the password:

$sql_script = 'select * from USERS where password="'.$digested_password.'"'

Fourth, profit.

So, rather than picking a user and trying to reverse their password, the bad guy picks a common password and tries to find a user who is using it. Odds are on the bad guy's side...

Because the bad guy does these things, it would behove you to not let users choose common passwords. In this case, take a look at ProCheck, EnFilter or Hyppocrates (et al). They are filtering libraries that reject bad passwords. ProCheck achieves very high compression, and can digest multi-million word password lists into a 30KB data file.

As denoted in other answers, sets are data structures (and mathematical concepts) that do not preserve the element order -

However, by using a combination of sets and dictionaries, it is possible that you can achieve wathever you want - try using these snippets:

# save the element order in a dict:
x_dict = dict(x,y for y, x in enumerate(my_list) )
x_set = set(my_list)
#perform desired set operations
...
#retrieve ordered list from the set:
new_list = [None] * len(new_set)
for element in new_set:
   new_list[x_dict[element]] = element

Adding to @sefarkas' suggestion and using quantile as cut-offs, one could explore the following option:

newdata <- subset(mydata,!(mydata$var > quantile(mydata$var, probs=c(.01, .99))[2] | mydata$var < quantile(mydata$var, probs=c(.01, .99))[1]) ) 

This will remove the points points beyond the 99th quantile. Care should be taken like what aL3Xa was saying about keeping outliers. It should be removed only for getting an alternative conservative view of the data.

This is answered in the comments; package-lock.json is a feature in npm v5 and higher. npm shrinkwrap is how you create a lockfile in all versions of npm.

If you are doing this in more than one place in your application it would make sense to use a client-side JSON database because creating custom search functions is messy and less maintainable than the alternative.

Check out ForerunnerDB which provides you with a very powerful client-side JSON database system and includes a very simple query language to help you do exactly what you are looking for:

// Create a new instance of ForerunnerDB and then ask for a database
var fdb = new ForerunnerDB(),
    db = fdb.db('myTestDatabase'),
    coll;

// Create our new collection (like a MySQL table) and change the default
// primary key from "_id" to "id"
coll = db.collection('myCollection', {primaryKey: 'id'});

// Insert our records into the collection
coll.insert([
    {"name":"my Name","id":12,"type":"car owner"},
    {"name":"my Name2","id":13,"type":"car owner2"},
    {"name":"my Name4","id":14,"type":"car owner3"},
    {"name":"my Name4","id":15,"type":"car owner5"}
]);

// Search the collection for the string "my nam" as a case insensitive
// regular expression - this search will match all records because every
// name field has the text "my Nam" in it
var searchResultArray = coll.find({
    name: /my nam/i
});

console.log(searchResultArray);

/* Outputs
[
    {"name":"my Name","id":12,"type":"car owner"},
    {"name":"my Name2","id":13,"type":"car owner2"},
    {"name":"my Name4","id":14,"type":"car owner3"},
    {"name":"my Name4","id":15,"type":"car owner5"}
]

Using this code for Navigating next viewcontroller,if you are using storyboard means follow this below code,

UIStoryboard *board;

if (!self.storyboard)
{
    board = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
}
else
{
    board = self.storyboard;
}

ViewController *View = [board instantiateViewControllerWithIdentifier:@"yourstoryboardname"];
[self.navigationController pushViewController:View animated:YES];
