It's empty by default. You'll find a bunch of settings in /etc/apache2/apache2.conf.

In there it does this:

# Include all the user configurations:
Include httpd.conf

As the main question:

Anybody know why this is not allowed?

is still not answered, I did a quick search and found a relatively new addition from a MySQL developer at MySQL Bugs:

[17 Mar 2017 15:11] Ståle Deraas

Posted by developer:

This is indeed a valid feature request, and at first glance it might seem trivial to add. But TEXT/BLOBS values are not stored directly in the record buffer used for reading/updating tables. So it is a bit more complex to assign default values for them.

This is no definite answer, but at least a starting point for the why question.

In the mean time, I'll just code around it and either make the column nullable or explicitly assign a (default '') value for each insert from the application code...

I was also facing same issue & notice that this error occurred because the selector on which I am using select2 did not exist or was not loaded.

So make sure that $("#selector") exists by doing

if ($("#selector").length > 0)
   $("#selector").select2();

$(".pushme").click(function () {
  var button = $(this);
  button.text(button.text() == "PUSH ME" ? "DON'T PUSH ME" : "PUSH ME")           
});

This ternary operator has an implicit return. If the expression before ? is true it returns "DON'T PUSH ME", else returns "PUSH ME"

This if-else statement:

if (condition) { return A }
else { return B }

has the equivalent ternary expression:

condition ? A : B

Most answers suggest appending '%' at the end. I would rather prefer Intl.NumberFormat() with { style: 'percent'}

var num = 25;_x000D_
_x000D_
var option = {_x000D_
  style: 'percent'_x000D_
_x000D_
};_x000D_
var formatter = new Intl.NumberFormat("en-US", option);_x000D_
var percentFormat = formatter.format(num / 100);_x000D_
console.log(percentFormat);

what are Access Specifiers?

There are 3 access specifiers for a class/struct/Union in C++. These access specifiers define how the members of the class can be accessed. Of course, any member of a class is accessible within that class(Inside any member function of that same class). Moving ahead to type of access specifiers, they are:

Public - The members declared as Public are accessible from outside the Class through an object of the class.

Protected - The members declared as Protected are accessible from outside the class BUT only in a class derived from it.

Private - These members are only accessible from within the class. No outside Access is allowed.

An Source Code Example:

class MyClass
{
    public:
        int a;
    protected:
        int b;
    private:
        int c;
};

int main()
{
    MyClass obj;
    obj.a = 10;     //Allowed
    obj.b = 20;     //Not Allowed, gives compiler error
    obj.c = 30;     //Not Allowed, gives compiler error
}

Inheritance and Access Specifiers

Inheritance in C++ can be one of the following types:

• Private Inheritance
• Public Inheritance
• Protected inheritance

Here are the member access rules with respect to each of these:

First and most important rule Private members of a class are never accessible from anywhere except the members of the same class.

Public Inheritance:

All Public members of the Base Class become Public Members of the derived class &
All Protected members of the Base Class become Protected Members of the Derived Class.

i.e. No change in the Access of the members. The access rules we discussed before are further then applied to these members.

Code Example:

Class Base
{
    public:
        int a;
    protected:
        int b;
    private:
        int c;
};

class Derived:public Base
{
    void doSomething()
    {
        a = 10;  //Allowed 
        b = 20;  //Allowed
        c = 30;  //Not Allowed, Compiler Error
    }
};

int main()
{
    Derived obj;
    obj.a = 10;  //Allowed
    obj.b = 20;  //Not Allowed, Compiler Error
    obj.c = 30;  //Not Allowed, Compiler Error

}

Private Inheritance:

All Public members of the Base Class become Private Members of the Derived class &
All Protected members of the Base Class become Private Members of the Derived Class.

An code Example:

Class Base
{
    public:
      int a;
    protected:
      int b;
    private:
      int c;
};

class Derived:private Base   //Not mentioning private is OK because for classes it  defaults to private 
{
    void doSomething()
    {
        a = 10;  //Allowed 
        b = 20;  //Allowed
        c = 30;  //Not Allowed, Compiler Error
    }
};

class Derived2:public Derived
{
    void doSomethingMore()
    {
        a = 10;  //Not Allowed, Compiler Error, a is private member of Derived now
        b = 20;  //Not Allowed, Compiler Error, b is private member of Derived now
        c = 30;  //Not Allowed, Compiler Error
    }
};

int main()
{
    Derived obj;
    obj.a = 10;  //Not Allowed, Compiler Error
    obj.b = 20;  //Not Allowed, Compiler Error
    obj.c = 30;  //Not Allowed, Compiler Error

}

Protected Inheritance:

All Public members of the Base Class become Protected Members of the derived class &
All Protected members of the Base Class become Protected Members of the Derived Class.

A Code Example:

Class Base
{
    public:
        int a;
    protected:
        int b;
    private:
        int c;
};

class Derived:protected Base  
{
    void doSomething()
    {
        a = 10;  //Allowed 
        b = 20;  //Allowed
        c = 30;  //Not Allowed, Compiler Error
    }
};

class Derived2:public Derived
{
    void doSomethingMore()
    {
        a = 10;  //Allowed, a is protected member inside Derived & Derived2 is public derivation from Derived, a is now protected member of Derived2
        b = 20;  //Allowed, b is protected member inside Derived & Derived2 is public derivation from Derived, b is now protected member of Derived2
        c = 30;  //Not Allowed, Compiler Error
    }
};

int main()
{
    Derived obj;
    obj.a = 10;  //Not Allowed, Compiler Error
    obj.b = 20;  //Not Allowed, Compiler Error
    obj.c = 30;  //Not Allowed, Compiler Error
}

Remember the same access rules apply to the classes and members down the inheritance hierarchy.

Important points to note:

- Access Specification is per-Class not per-Object

Note that the access specification C++ work on per-Class basis and not per-object basis.
A good example of this is that in a copy constructor or Copy Assignment operator function, all the members of the object being passed can be accessed.

- A Derived class can only access members of its own Base class

Consider the following code example:

class Myclass
{ 
    protected: 
       int x; 
}; 

class derived : public Myclass
{
    public: 
        void f( Myclass& obj ) 
        { 
            obj.x = 5; 
        } 
};

int main()
{
    return 0;
}

It gives an compilation error:

prog.cpp:4: error: ‘int Myclass::x’ is protected

Because the derived class can only access members of its own Base Class. Note that the object obj being passed here is no way related to the derived class function in which it is being accessed, it is an altogether different object and hence derived member function cannot access its members.

What is a friend? How does friend affect access specification rules?

You can declare a function or class as friend of another class. When you do so the access specification rules do not apply to the friended class/function. The class or function can access all the members of that particular class.

So do friends break Encapsulation?

No they don't, On the contrary they enhance Encapsulation!

friendship is used to indicate a intentional strong coupling between two entities.
If there exists a special relationship between two entities such that one needs access to others private or protected members but You do not want everyone to have access by using the public access specifier then you should use friendship.

On SourceTree for Mac, right click the files you want to discard (in the Files in the working tree list), and choose Reset.

On SourceTree for Windows, right click the files you want to discard (in the Working Copy Changes list), and choose Discard.

On git, you'd simply do:

git reset --hard to discard changes made to versioned files;

git clean -xdf to erase new (untracked) files, including ignored ones (the x option). d is to also remove untracked directories and f to force.

As a general advice, I would recommend not stealing the focus from the address bar. (Jeff already talked about that.)

Web page can take some time to load, which means that your focus change can occur some long time after the user typed the pae URL. Then he could have changed his mind and be back to url typing while you will be loading your page and stealing the focus to put it in your textbox.

That's the one and only reason that made me remove Google as my start page.

Of course, if you control the network (local network) or if the focus change is to solve an important usability issue, forget all I just said :)

string result = Regex.Replace(anytext, @"<(.|\n)*?>", string.Empty);

is there a special guideline that should be followed

There is no "standard" way to do batch files, because the vast majority of their authors and maintainers either don't understand programming concepts, or they think they don't apply to batch files.

But I am a programmer. I'm used to compiling, and I'm used to debuggers. Batch files aren't compiled, and you can't run them through a debugger, so they make me nervous. I suggest you be extra strict on what you write, so you can be very sure it will do what you think it does.

There are some coding standards that say: If you write an if statement, you must use braces, even if you don't have an else clause. This saves you from subtle, hard-to-debug problems, and is unambiguously readable. I see no reason you couldn't apply this reasoning to batch files.

Let's take a look at your code.

IF EXIST somefile.txt IF EXIST someotherfile.txt SET var=somefile.txt,someotherfile.txt

And the IF syntax, from the command, HELP IF:

IF [NOT] ERRORLEVEL number command
IF [NOT] string1==string2 command
IF [NOT] EXISTS filename command

...

IF EXIST filename (
  command
) ELSE (
  other command
)

So you are chaining IF's as commands.

If you use the common coding-standard rule I mentioned above, you would always want to use parens. Here is how you would do so for your example code:

IF EXIST "somefile.txt" (
  IF EXIST "someotherfile.txt" (
    SET var="somefile.txt,someotherfile.txt"
  )
)

Make sure you cleanly format, and do some form of indentation. You do it in code, and you should do it in your batch scripts.

Also, you should also get in the habit of always quoting your file names, and getting the quoting right. There is some verbiage under HELP FOR and HELP SET that will help you with removing extra quotes when re-quoting strings.

Edit

From your comments, and re-reading your original question, it seems like you want to build a comma separated list of files that exist. For this case, you could simply use a bunch of if/else statements, but that would result in a bunch of duplicated logic, and would not be at all clean if you had more than two files.

A better way is to write a sub-routine that checks for a single file's existence, and appends to a variable if the file specified exists. Then just call that subroutine for each file you want to check for:

@ECHO OFF
SETLOCAL

REM Todo: Set global script variables here
CALL :MainScript
GOTO :EOF

REM MainScript()
:MainScript
  SETLOCAL

  CALL :AddIfExists "somefile.txt" "%files%" "files"
  CALL :AddIfExists "someotherfile.txt" "%files%" "files"

  ECHO.Files: %files%

  ENDLOCAL
GOTO :EOF

REM AddIfExists(filename, existingFilenames, returnVariableName)
:AddIfExists
  SETLOCAL

  IF EXIST "%~1" (
    SET "result=%~1"
  ) ELSE (
    SET "result="
  )

  (
    REM Cleanup, and return result - concatenate if necessary
    ENDLOCAL

    IF "%~2"=="" (
      SET "%~3=%result%"
    ) ELSE (
      SET "%~3=%~2,%result%"
    )
  )
GOTO :EOF

The answers given don't actually match your question, which implied a trailing number. Also, remember that you're getting a string back; if you actually need a number, cast the result:

item=item.replace('^.*\D(\d*)$', '$1');
if (!/^\d+$/.test(item)) throw 'parse error: number not found';
item=Number(item);

If you're dealing with numeric item ids on a web page, your code could also usefully accept an Element, extracting the number from its id (or its first parent with an id); if you've an Event handy, you can likely get the Element from that, too.

This version can do deep, shallow, or a specific number of levels:

/**
 * @param  array|object $array  array of mixed values to flatten
 * @param  int|boolean  $level  0:deep, 1:shallow, 2:2 levels, 3...
 * @return array
 */
function flatten($array, $level = 0) {
    $level = (int) $level;
    $result = array();
    foreach ($array as $i => $v) {
        if (0 <= $level && is_array($v)) {
            $v = flatten($v, $level > 1 ? $level - 1 : 0 - $level);
            $result = array_merge($result, $v);
        } elseif (is_int($i)) {
            $result[] = $v;
        } else {
            $result[$i] = $v; 
        }
    }
    return $result;
}

I usually find that ProgrammableWeb is a good place to go when looking for APIs.

One of your requirements is to preserve the original lists. If you create a new list and use addAll(), you are effectively doubling the number of references to the objects in your lists. This could lead to memory problems if your lists are very large.

If you don't need to modify the concatenated result, you can avoid this using a custom list implementation. The custom implementation class is more than one line, obviously...but using it is short and sweet.

CompositeUnmodifiableList.java:

public class CompositeUnmodifiableList<E> extends AbstractList<E> {

    private final List<E> list1;
    private final List<E> list2;

    public CompositeUnmodifiableList(List<E> list1, List<E> list2) {
        this.list1 = list1;
        this.list2 = list2;
    }

    @Override
    public E get(int index) {
        if (index < list1.size()) {
            return list1.get(index);
        }
        return list2.get(index-list1.size());
    }

    @Override
    public int size() {
        return list1.size() + list2.size();
    }
}

Usage:

List<String> newList = new CompositeUnmodifiableList<String>(listOne,listTwo);

From info gcc (emphasis mine):

-ansi

In C mode, this is equivalent to -std=c90. In C++ mode, it is equivalent to -std=c++98. This turns off certain features of GCC that are incompatible with ISO C90 (when compiling C code), or of standard C++ (when compiling C++ code), such as the asm and typeof keywords, and predefined macros such as 'unix' and 'vax' that identify the type of system you are using. It also enables the undesirable and rarely used ISO trigraph feature. For the C compiler, it disables recognition of C++ style // comments as well as the inline keyword.

(It uses vax in the example instead of linux because when it was written maybe it was more popular ;-).

The basic idea is that GCC only tries to fully comply with the ISO standards when it is invoked with the -ansi option.

You can try this click event

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    if (e.RowIndex >= 0)
    {
        DataGridViewRow row = this.dataGridView1.Rows[e.RowIndex];
        Eid_txt.Text = row.Cells["Employee ID"].Value.ToString();
        Name_txt.Text = row.Cells["First Name"].Value.ToString();
        Surname_txt.Text = row.Cells["Last Name"].Value.ToString();

4 years after the question got posted, but maybe it will help others who run into this problem. The answer has been posted elsewhere on StackExchange as well, but I lost the link and it's hard to find.

ANSWER: In jQueryTOOLS, the jQuery 'core' is also embedded if you use the default download.

When you load jQuery and jQuery tools, jQuery core gets defined twice and will 'unset' any plugins. 'Draggable' (from jQuery-UI) is such a plug-in.

The solution is to use jQuery tools WITHOUT the jQuery 'core' files and everything will work fine.

If you need a random number in the range [double.MinValue; double.MaxValue]

// Because of:
double.MaxValue - double.MinValue == double.PositiveInfinity

// This will be equals to NaN or PositiveInfinity
random.NextDouble() * (double.MaxValue - double.MinValue)

Use instead:

public static class RandomExtensions
{
    public static double NextDoubleInMinMaxRange(this Random random)
    {
        var bytes = new byte[sizeof(double)];
        var value = default(double);
        while (true)
        {
            random.NextBytes(bytes);
            value = BitConverter.ToDouble(bytes, 0);
            if (!double.IsNaN(value) && !double.IsInfinity(value))
                return value;
        }
    }
}

Try with

f.mkdirs() then createNewFile()

In your $CATALINA_BASE/conf/context.xml add block below before </Context>

<Resources cachingAllowed="true" cacheMaxSize="100000" />

This is just a note for those who might find this question later, but you don't have to pull in the response to change the content type. Here's an example below to do just that:

@RequestMapping(method = RequestMethod.GET, value="/controller")
public ResponseEntity<byte[]> displayUploadedFile()
{
  HttpHeaders headers = new HttpHeaders();
  String disposition = INLINE;
  String fileName = "";
  headers.setContentType(MediaType.APPLICATION_OCTET_STREAM);

  //Load your attachment here

  if (Arrays.equals(Constants.HEADER_BYTES_PDF, contentBytes)) {
    headers.setContentType(MediaType.valueOf("application/pdf"));
    fileName += ".pdf";
  }

  if (Arrays.equals(Constants.HEADER_BYTES_TIFF_BIG_ENDIAN, contentBytes)
      || Arrays.equals(Constantsr.HEADER_BYTES_TIFF_LITTLE_ENDIAN, contentBytes)) {
    headers.setContentType(MediaType.valueOf("image/tiff"));
    fileName += ".tif";
  }

  if (Arrays.equals(Constants.HEADER_BYTES_JPEG, contentBytes)) {
    headers.setContentType(MediaType.IMAGE_JPEG);
    fileName += ".jpg";
  }

  //Handle other types if necessary

  headers.add("Content-Disposition", , disposition + ";filename=" + fileName);
  return new ResponseEntity<byte[]>(uploadedBytes, headers, HttpStatus.OK);
}

To anyone using gradle: don't include the project source, but instead download it using SDK Manager and add this line to dependencies:

To style for many smartphones with smaller screens, you could write:

@media screen and (max-width:480px) { … } 

To block older browsers from seeing an iPhone or Android phone style sheet, you could write:

@media only screen and (max-width: 480px;) { … }

Yes - their performance characteristics differ significantly. It would probably be better to call them SortedList and SortedTree as that reflects the implementation more closely.

Look at the MSDN docs for each of them (SortedList, SortedDictionary) for details of the performance for different operations in different situtations. Here's a nice summary (from the SortedDictionary docs):

The SortedDictionary<TKey, TValue> generic class is a binary search tree with O(log n) retrieval, where n is the number of elements in the dictionary. In this, it is similar to the SortedList<TKey, TValue> generic class. The two classes have similar object models, and both have O(log n) retrieval. Where the two classes differ is in memory use and speed of insertion and removal:

• SortedList<TKey, TValue> uses less memory than SortedDictionary<TKey, TValue>.

• SortedDictionary<TKey, TValue> has faster insertion and removal operations for unsorted data, O(log n) as opposed to O(n) for SortedList<TKey, TValue>.

• If the list is populated all at once from sorted data, SortedList<TKey, TValue> is faster than SortedDictionary<TKey, TValue>.

(SortedList actually maintains a sorted array, rather than using a tree. It still uses binary search to find elements.)

1. Your call to MessageBox.Show needs to pass MessageBoxButtons.YesNo to get the Yes/No buttons instead of the OK button.

2. Compare the result of that call (which will block execution until the dialog returns) to DialogResult.Yes....

if (MessageBox.Show("Are you sure?", "Confirm", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
{
    // user clicked yes
}
else
{
    // user clicked no
}

You can trigger Jenkins builds remotely and to pass parameters by using the following query.

JENKINS_URL/job/job-name/buildWithParameters?token=TOKEN_NAME&param_name1=value&param_name1=value

JENKINS_URL (can be) = https://<your domain name or server address>

TOKE_NAME can be created using configure tab

    function setToggleInputsinPnl(pnlName) {
    var domCount = pnlName.length;
    for (var i = 0; i < domCount; i++) {
        if (pnlName[i].type == 'text') {
            pnlName[i].value = '';
        } else if (pnlName[i].type == 'select-one') {
               pnlName[i].value = '';
        }
    }
}

grep -n "Pattern" in_file.ext | wc -l 

To extract matched pattern

sed -n '/pattern/p' file.est

To display line numbers on which pattern was matched

grep -n "pattern" file.ext | cut -f1 -d:

Configure another port number(eg:8181) in /src/main/resources/application.properties

server.port=8181

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

you should use this code:

$json = json_encode(array_map('utf8_encode', $arr))

array_map function converts special characters in UTF8 standard

I have read that while the underlying chips are essentially the same, the design of the board is different.

Gamers want performance, and tend to favor overclocking and other things to get high frame rates but which maybe burn out the hardware occasionally.

Businesses want reliability, and tend to favor underclocking so they can be sure that their people can keep working.

Also, I have read that the quadro boards use ECC memory.

If you don't know what ECC memory is about: it's a [relatively] well known fact that sometimes memory "flips bits (experiences errors)". This does not happen too often, but is an unavoidable consequence of the underlying physics of the memory cards and the world we live in. ECC memory adds a small percentage to the cost and a small penalty to the performance and has enough redundancy to correct occasional errors and to detect (but not correct) somewhat rarer errors. Gamers don't care about that kind of accuracy because for gamers those are just very rare visual glitches. Companies do care about that kind of accuracy because those glitches would wind up as glitches in their products or else would require more double or triple checking (which winds up being a 2x or 3x performance penalty for some part of their business).

Another issue I have read about has to do with hooking up the graphics card to third party hardware. In other words: sending the images to another card or to another machine instead of to the screen. Most gamers are just using canned software that doesn't have any use for such capabilities. Companies that use that kind of thing get orders of magnitude performance gains from the more direct connections.

After a lot of fiddling, got it working (only tested in Webkit) using:

font-family: "HelveticaNeue-CondensedBold";

font-stretch was dropped between CSS2 and 2.1, though is back in CSS3, but is only supported in IE9 (never thought I'd be able to say that about any CSS prop!)

This works because I'm using the postscript name (find the font in Font Book, hit cmd+I), which is non-standard behaviour. It's probably worth using:

font-family: "HelveticaNeue-CondensedBold", "Helvetica Neue";

As a fallback, else other browsers might default to serif if they can't work it out.

Demo: http://jsfiddle.net/ndFTL/12/

Can you change the if condition to this:

if (!is.na(comments[l])) print(comments[l]);

You can only check for NA values with is.na().

I prefer using Hamcrest because it gives much better output in case of a failure

Assert.assertThat(listUnderTest, 
       IsIterableContainingInOrder.contains(expectedList.toArray()));

Instead of reporting

expected true, got false

it will report

expected List containing "1, 2, 3, ..." got list containing "4, 6, 2, ..."

IsIterableContainingInOrder.contain

Hamcrest

According to the Javadoc:

Creates a matcher for Iterables that matches when a single pass over the examined Iterable yields a series of items, each logically equal to the corresponding item in the specified items. For a positive match, the examined iterable must be of the same length as the number of specified items

So the listUnderTest must have the same number of elements and each element must match the expected values in order.

You can use .append() for simply concatenating strings.

std::string s = "string1";
s.append("string2");

I think you might even be able to do:

std::string s = "string1";
s += "string2";

As for the formatting operations of C#'s StringBuilder, I believe snprintf (or sprintf if you want to risk writing buggy code ;-) ) into a character array and convert back to a string is about the only option.

A good plugin that I have used before is DataTables.

This might be the case too.

you have not specified the file in a variable and redirecting output to it, then bash will throw this error.

files=`ls`
out_file = /path/to/output_file.t
for i in `echo "$files"`;
do
    content=`cat $i` 
    echo "${content}  ${i}" >> ${out_file}
done

out_file variable is not set up correctly so keep an eye on this too. BTW this code is printing all the content and its filename on the console.

Make sure that the variable that holds your angular.module is structured correctly.

This will fail with "Uncaught Error: [$injector:modulerr]":

var angApp = angular.module("angApp");

This works:

var angApp = angular.module("angApp", []);

It's a sneaky one since the error message doesn't point to one thing in particular (Thus the wide variety of answers). Additionally, most js linters won't catch the particulars. Keep at it!

Search for copyLinesDownAction or copyLinesUpAction in your keyboard shortcuts

Usually, it is SHIFT+ALT+?

Instead of parsing it manually it's better to use pathinfo function:

$path_parts = pathinfo($value);
$extension = strtolower($path_parts['extension']);
$fileName = $path_parts['filename'];

if (MaterialTextBox.Text.length==0)
{

}

Here's an updated version (Swift 3.0.1) from Ben Packard's answer.

import UIKit

@IBDesignable class BorderedButton: UIButton {

    @IBInspectable var borderColor: UIColor? {
        didSet {
            if let bColor = borderColor {
                self.layer.borderColor = bColor.cgColor
            }
        }
    }

    @IBInspectable var borderWidth: CGFloat = 0 {
        didSet {
            self.layer.borderWidth = borderWidth
        }
    }

    override var isHighlighted: Bool {
        didSet {
            guard let currentBorderColor = borderColor else {
                return
            }

            let fadedColor = currentBorderColor.withAlphaComponent(0.2).cgColor

            if isHighlighted {
                layer.borderColor = fadedColor
            } else {

                self.layer.borderColor = currentBorderColor.cgColor

                let animation = CABasicAnimation(keyPath: "borderColor")
                animation.fromValue = fadedColor
                animation.toValue = currentBorderColor.cgColor
                animation.duration = 0.4
                self.layer.add(animation, forKey: "")
            }
        }
    }
}

The resulting button can be used inside your StoryBoard thanks to the @IBDesignable and @IBInspectable tags.

Also the two properties defined, allow you to set the border width and color directly on interface builder and preview the result.

Other properties could be added in a similar fashion, for border radius and highlight fading time.

As the dictionary documentation for python 2 and python 3 would tell you, in python 2 items returns a list, while iteritems returns a iterator.

In python 3, items returns a view, which is pretty much the same as an iterator.

If you are using python 2, you may want to user iteritems if you are dealing with large dictionaries and all you want to do is iterate over the items (not necessarily copy them to a list)

adbd has a compilation flag/option to enable root access: ALLOW_ADBD_ROOT=1.

Up to Android 9: If adbd on your device is compiled without that flag, it will always drop privileges when starting up and thus "adb root" will not help at all. I had to patch the calls to setuid(), setgid(), setgroups() and the capability drops out of the binary myself to get a permanently rooted adbd on my ebook reader.

With Android 10 this changed; when the phone/tablet is unlocked (ro.boot.verifiedbootstate == "orange"), then adb root mode is possible in any case.

just in case you're facing this problem under windows 10 , add the group of users "youcomputer\Users" on the security Tab and grant it full control , that solved my issue

I came up with this solution.

Let's assume that we want to add some html to the element with unsafe data from the user or database.

var unsafe = 'some unsafe data like <script>alert("oops");</script> here';

var html = '';
html += '<div>';
html += '<p>' + unsafe + '</p>';
html += '</div>';

element.html(html);

It's unsafe against XSS attacks. Now add this.

$(document.createElement('div')).html(unsafe).text();

So it is

var unsafe = 'some unsafe data like <script>alert("oops");</script> here';

var html = '';
html += '<div>';
html += '<p>' + $(document.createElement('div')).html(unsafe).text(); + '</p>';
html += '</div>';

element.html(html);

To me this is much easier than using .replace() and it'll remove!!! all possible html tags (I hope).

I had the same problem. This what worked for me:

1. Go to SQL Server Management Studio and run it as Administrator.
2. Choose Security -> Then Logins
3. Choose the usernames or whatever users that will access your database under the Logins and Double Click it.
4. Give them a Server Roles that will give them credentials to create database. On my case, public was already checked so I checked dbcreator and sysadmin.
5. Run update-database again on Package Manager Console. Database should now successfully created.

Here is an image so that you can get the bigger picture, I blurred my credentials of course:

If you say that it works with accessing directly manageproducts.do?option=1 in the browser then it should work with:

$.get('manageproducts.do', { option: '1' }, function(data) {
    ...
});

as it would send the same GET request.

the only solution worked for me was using java keytool and generating a .keystore file the command line and then use that .keystore file to sign my app

you can find the java keytool at this directory C:\Program Files\Java\jre7\bin

open a command window and switch to that directory and enter a command like this

keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000

Keytool prompts you to provide passwords for the keystore, your name , company etc . note that at the last prompt you need to enter yes.

It then generates the keystore as a file called my-release-key.keystore in the directory you're in. The keystore and key are protected by the passwords you entered. The keystore contains a single key, valid for 10000 days. The alias is a name that you — will use later, to refer to this keystore when signing your application.

For more information about Keytool, see the documentation at: http://docs.oracle.com/javase/6/docs/technotes/tools/windows/keytool.html

and for more information on signing Android apps go here: http://developer.android.com/tools/publishing/app-signing.html

Your approach is OK

Maybe slightly clearer (to me anyway!)

UPDATE
  T1
SET
  [Description] = t2.[Description]
FROM
   Table1 T1
   JOIN
   [Table2] t2 ON t2.[ID] = t1.DescriptionID

Both this and your query should run the same performance wise because it is the same query, just laid out differently.

I don't know specifics of your issue, but if the function needs the value then it can be a parameter passed through the call.

Globals are considered bad because globals state and multiple modifiers can create hard to follow code and strange errors. To many actors fiddling with something can create chaos.

'b' should be in capital letter in document.getElementById modified code jsfiddle

function test()
{

var element = document.createElement("div");
element.appendChild(document.createTextNode('The man who mistook his wife for a hat'));
document.getElementById('lc').appendChild(element);
 //document.body.appendChild(element);
 }

This doesn't answer how to add them to your POM, and may be a no brainer, but would just adding the lib dir to your classpath work? I know that is what I do when I need an external jar that I don't want to add to my Maven repos.

Hope this helps.

The default limit for the length of the request line is 8190 bytes (see LimitRequestLine directive). And if we subtract three bytes for the request method (i.e. GET), eight bytes for the version information (i.e. HTTP/1.0/HTTP/1.1) and two bytes for the separating space, we end up with 8177 bytes for the URI path plus query.

I almost never create a table without a numeric primary key. If there is also a natural key that should be unique, I also put a unique index on it. Joins are faster on integers than multicolumn natural keys, data only needs to change in one place (natural keys tend to need to be updated which is a bad thing when it is in primary key - foreign key relationships). If you are going to need replication use a GUID instead of an integer, but for the most part I prefer a key that is user readable especially if they need to see it to distinguish between John Smith and John Smith.

The few times I don't create a surrogate key are when I have a joining table that is involved in a many-to-many relationship. In this case I declare both fields as the primary key.

int[][] matrix = {
    {1,2,3},
    {4,5,6},
    {7,8,9},
    {10,11,12}
};

printMatrix(matrix);

public void printMatrix(int[][] m){
    try{
        int rows = m.length;
        int columns = m[0].length;
        String str = "|\t";

        for(int i=0;i<rows;i++){
            for(int j=0;j<columns;j++){
                str += m[i][j] + "\t";
            }

            System.out.println(str + "|");
            str = "|\t";
        }

    }catch(Exception e){System.out.println("Matrix is empty!!");}
}

Output:

That's the default margin/padding of the body element.

Some browsers have a default margin, some a default padding, and both are applied as a padding in the body element.

Add this to your CSS:

body { margin: 0; padding: 0; }

If you want only normal IP-s (no slashes), here:

^(?:[0-9a-f]{1,4}(?:::)?){0,7}::[0-9a-f]+$

I use it for my syntax highlighter in hosts file editor application. Works as charm.

function iterateNumber(N, f) {
    let n = N;
    var length = Math.log(n) * Math.LOG10E + 1 | 0;
    for (let i = 0; i < length; i++) {
        const pow = Math.pow(10, length - i - 1)
        let c = (n - (n % pow)) / pow
        f(c, i)
        n %= pow
    }
}

Try this:

 git fetch --all
 git reset --hard origin/master

Explanation:

git fetch downloads the latest from remote without trying to merge or rebase anything.

Here's a script that uses FOR to build a fully qualified path, and then pushd to test whether the path is a directory. Notice how it works for paths with spaces, as well as network paths.

@echo off
if [%1]==[] goto usage

for /f "delims=" %%i in ("%~1") do set MYPATH="%%~fi"
pushd %MYPATH% 2>nul
if errorlevel 1 goto notdir
goto isdir

:notdir
echo not a directory
goto exit

:isdir
popd
echo is a directory
goto exit

:usage
echo Usage:  %0 DIRECTORY_TO_TEST

:exit

Sample output with the above saved as "isdir.bat":

C:\>isdir c:\Windows\system32

You are getting this problem because the activity you are trying to apply the android:theme="@android:style/Theme.Holo.Light.NoActionBar.Fullscreen"> to is extending ActionBarActivity which requires the AppCompat theme to be applied.

Extend your activity from Activity rather than from ActionBarActivity

You might have to change your Java class accordingly little bit.

If you want to remove status bar too then use this before setContentView(layout) in onCreateView method

        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
        WindowManager.LayoutParams.FLAG_FULLSCREEN);

You can use js. It should work as expected.

function myFunction(){
    var x = document.getElementById("DIV");
  x.style.backgroundColor="red";
  x.style.cursor="pointer";
  x.style.color="white"
}
function my2Function(){
    var x = document.getElementById("DIV");
  x.style.backgroundColor="white";
  x.style.color="red"
}

.mydiv {
  background-color: white;
  color: red;
}

<div class = "mydiv" id="DIV" onmouseover="myFunction()" onmouseleave="my2Function()">
  hi
</div>

Below styles will vertically center it for you.

p.event_desc {
 font: bold 12px "Helvetica Neue", Helvetica, Arial, sans-serif;
 line-height: 14px;
 height: 35px;
 display: table-cell;
 vertical-align: middle;
 margin: 0px;
}

If the input field has a class name formData use this : $(".formData").val("data")

If the input field has an id attribute name formData use this : $("#formData").val("data")

If the input name is given use this : $("input[name='formData']").val("data")

You can also mention the type. Then it will refer to all the inputs of that type and the given class name: $("input[type='text'].formData").val("data")

This is taken from the docs and it works very well. Here is the link

• m - for classes that set margin
• p - for classes that set padding

Where sides are one of:

• t - for classes that set margin-top or padding-top
• b - for classes that set margin-bottom or padding-bottom
• l - for classes that set margin-left or padding-left
• r - for classes that set margin-right or padding-right

if you want to give margin to the left use mt-x where x stands for [1,2,3,4,5]

same for padding

example be like

<div class = "mt-5"></div>
<div class = "pt-5"></div>

Use only p-x or m-x for getting padding and margin of x from all sides.

replace "150x150" with 720x720 and remove /vp/ from the link.it should work.

Using the answers above, I created a quick static method that can easily be re-used. It only aims at tinting the progress color for the activated stars. The stars that are not activated remain grey.

    public static RatingBar tintRatingBar (RatingBar ratingBar, int progressColor)if (ratingBar.getProgressDrawable() instanceof LayerDrawable) {
        LayerDrawable progressDrawable = (LayerDrawable) ratingBar.getProgressDrawable();
        Drawable drawable = progressDrawable.getDrawable(2);
        Drawable compat = DrawableCompat.wrap(drawable);
        DrawableCompat.setTint(compat, progressColor);
        Drawable[] drawables = new Drawable[3];
        drawables[2] = compat;

        drawables[0] = progressDrawable.getDrawable(0);
        drawables[1] = progressDrawable.getDrawable(1);

        LayerDrawable layerDrawable = new LayerDrawable(drawables);

        ratingBar.setProgressDrawable(layerDrawable);

        return ratingBar;
    }
    else {
        Drawable progressDrawable =  ratingBar.getProgressDrawable();
        Drawable compat = DrawableCompat.wrap(progressDrawable);
        DrawableCompat.setTint(compat, progressColor);
        ratingBar.setProgressDrawable(compat);
        return ratingBar;
    }
}

Just pass your rating bar and a Color using getResources().getColor(R.color.my_rating_color)

As you can see, I use DrawableCompat so it's backward compatible.

EDIT : This method does not work on API21 (go figure why). You end up with a NullPointerException when calling setProgressBar. I ended up disabling the whole method on API >= 21.

For API >= 21, I use SupperPuccio solution.

You can pre-fetch your data by using Resolvers in Angular2+, Resolvers process your data before your Component fully be loaded.

There are many cases that you want to load your component only if there is certain thing happening, for example navigate to Dashboard only if the person already logged in, in this case Resolvers are so handy.

Look at the simple diagram I created for you for one of the way you can use the resolver to send the data to your component.

Applying Resolver to your code is pretty simple, I created the snippets for you to see how the Resolver can be created:

import { Injectable } from '@angular/core';
import { Router, Resolve, RouterStateSnapshot, ActivatedRouteSnapshot } from '@angular/router';
import { MyData, MyService } from './my.service';

@Injectable()
export class MyResolver implements Resolve<MyData> {
  constructor(private ms: MyService, private router: Router) {}

  resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Promise<MyData> {
    let id = route.params['id'];

    return this.ms.getId(id).then(data => {
      if (data) {
        return data;
      } else {
        this.router.navigate(['/login']);
        return;
      }
    });
  }
}

and in the module:

import { MyResolver } from './my-resolver.service';

@NgModule({
  imports: [
    RouterModule.forChild(myRoutes)
  ],
  exports: [
    RouterModule
  ],
  providers: [
    MyResolver
  ]
})
export class MyModule { }

and you can access it in your Component like this:

/////
 ngOnInit() {
    this.route.data
      .subscribe((data: { mydata: myData }) => {
        this.id = data.mydata.id;
      });
  }
/////

And in the Route something like this (usually in the app.routing.ts file):

////
{path: 'yourpath/:id', component: YourComponent, resolve: { myData: MyResolver}}
////

To get rid use array_unique(). To detect if have any use count(array_unique()) and compare to count($array).

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="android:Theme.Holo.NoActionBar">
        <item name="android:windowBackground">@android:color/black</item>
    </style>

</resources>

While looking at your code, the only thing I see wrong, is when you try to load the second database:

$DB2=$this->load->database($config);

When you want to retrieve the database object, you have to pass TRUE in the second argument.

From the Codeigniter User Guide:

By setting the second parameter to TRUE (boolean) the function will return the database object.

So, your code should instead be:

$DB2=$this->load->database($config, TRUE);

That will make it work.

Using next or readlines etc, is not necessary. As the documentation says: "For reading lines from a file, you can loop over the file object. This is memory efficient, fast, and leads to simple code".

Here's an example:

with open('/path/to/file') as myfile:
    for line in myfile:
        print(line)

Change Integrated security to false in the connection string.

You can check/verify this by opening up the SQL management studio with the username/password you have and see if you can connect/open the database from there. NOTE! Could be a firewall issue as well.

If you want to use it from Boost TR1 instead

shared_ptr Example

We should first read the documentation on proxy_pass carefully and fully.

The URI passed to upstream server is determined based on whether "proxy_pass" directive is used with URI or not. Trailing slash in proxy_pass directive means that URI is present and equal to /. Absense of trailing slash means hat URI is absent.

Proxy_pass with URI:

location /some_dir/ {
    proxy_pass http://some_server/;
}

With the above, there's the following proxy:

http:// your_server/some_dir/ some_subdir/some_file ->
http:// some_server/          some_subdir/some_file

Basically, /some_dir/ gets replaced by / to change the request path from /some_dir/some_subdir/some_file to /some_subdir/some_file.

Proxy_pass without URI:

location /some_dir/ {
    proxy_pass http://some_server;
}

With the second (no trailing slash): the proxy goes like this:

http:// your_server /some_dir/some_subdir/some_file ->
http:// some_server /some_dir/some_subdir/some_file

Basically, the full original request path gets passed on without changes.

So, in your case, it seems you should just drop the trailing slash to get what you want.

Caveat

Note that automatic rewrite only works if you don't use variables in proxy_pass. If you use variables, you should do rewrite yourself:

location /some_dir/ {
  rewrite    /some_dir/(.*) /$1 break;
  proxy_pass $upstream_server;
}

There are other cases where rewrite wouldn't work, that's why reading documentation is a must.

Edit

Reading your question again, it seems I may have missed that you just want to edit the html output.

For that, you can use the sub_filter directive. Something like ...

location /admin/ {
    proxy_pass http://localhost:8080/;
    sub_filter "http://your_server/" "http://your_server/admin/";
    sub_filter_once off;
}

Basically, the string you want to replace and the replacement string

You can disable the caching by doing the following:

NSURLCache *sharedCache = [[NSURLCache alloc] initWithMemoryCapacity:0 diskCapacity:0 diskPath:nil];
[NSURLCache setSharedURLCache:sharedCache];

[NSURLCache setSharedURLCache:sharedCache];

You should not need to add this back in. This was removed purposefully. The documentation has changed somewhat and the CSS class that is necessary ("nav-stacked") is only mentioned under the pills component, but should work for tabs as well.

This tutorial shows how to use the Bootstrap 3 setup properly to do vertical tabs:

For reset all field in one form you can use event.target.reset()

const app = new Vue({_x000D_
    el: '#app',    _x000D_
    data(){_x000D_
 return{        _x000D_
            name : null,_x000D_
     lastname : null,_x000D_
     address : null_x000D_
 }_x000D_
    },_x000D_
    methods: {_x000D_
        submitForm : function(event){_x000D_
            event.preventDefault(),_x000D_
            //process...             _x000D_
            event.target.reset()_x000D_
        }_x000D_
    }_x000D_
_x000D_
});

When you use the extends template tag, you're saying that the current template extends another -- that it is a child template, dependent on a parent template. Django will look at your child template and use its content to populate the parent.

Everything that you want to use in a child template should be within blocks, which Django uses to populate the parent. If you want use an include statement in that child template, you have to put it within a block, for Django to make sense of it. Otherwise it just doesn't make sense and Django doesn't know what to do with it.

The Django documentation has a few really good examples of using blocks to replace blocks in the parent template.

This solution only for chrome browser. I am not sure about other browser.

1. Add "Modify Content-Type Options" extension in chrome browser.
2. Open "chrome-extension://jnfofbopfpaoeojgieggflbpcblhfhka/options.html" url in browser.
3. Add the rule for raw file url. For example:
   • URL Filter: https:///raw/master//fileName.html
   • Original Type: text/plain
   • Replacement Type: text/html
4. Open the file browser which you added url in rule (in step 3).

This problem has hounded me for some days now, so on finding the answer that affirmatively works with tvanfosson's answer above, I thought it would be worthwhile to emphasize the core part of the answer, and address some related catch ya's.

The core answer is this, sweet and simple:

filterContext.Result = new HttpUnauthorizedResult();

In my case I inherit from a base controller, so in each controller that inherits from it I override OnAuthorize:

protected override void OnAuthorization(AuthorizationContext filterContext)
{
    base.OnAuthorization(filterContext);
    YourAuth(filterContext); // do your own authorization logic here
}

The problem was that in 'YourAuth', I tried two things that I thought would not only work, but would also immediately terminate the request. Well, that is not how it works. So first, the two things that DO NOT work, unexpectedly:

filterContext.RequestContext.HttpContext.Response.Redirect("/Login"); // doesn't work!
FormsAuthentication.RedirectToLoginPage(); // doesn't work!

Not only do those not work, they don't end the request either. Which means the following:

if (!success) {
    filterContext.Result = new HttpUnauthorizedResult();
}
DoMoreStuffNowThatYouThinkYourAuthorized();

Well, even with the correct answer above, the flow of logic still continues! You will still hit DoMoreStuff... within OnAuthorize. So keep that in mind (DoMore... should be in an else therefore).

But with the correct answer, while OnAuthorize flow of logic continues till the end still, after that you really do get what you expect: a redirect to your login page (if you have one set in Forms auth in your webconfig).

But unexpectedly, 1) Response.Redirect("/Login") does not work: the Action method still gets called, and 2) FormsAuthentication.RedirectToLoginPage(); does the same thing: the Action method still gets called!

Which seems totally wrong to me, particularly with the latter: who would have thought that FormsAuthentication.RedirectToLoginPage does not end the request, or do the equivalant above of what filterContext.Result = new HttpUnauthorizedResult() does?

You need to import the module datetime first:

>>> import datetime

After that it works:

>>> import datetime
>>> date = datetime.date.today()
>>> date
datetime.date(2013, 11, 12)

var payeeCountry = document.getElementById( "payeeCountry" );
alert( payeeCountry.options[ yourSelect.selectedIndex ].value );

In IIS 7 and beyond:

web.config file:

<system.webServer>
  <security >
    <requestFiltering>
      <requestLimits maxAllowedContentLength="[Size In Bytes]" />
    </requestFiltering>
  </security>
</system.webServer>

You can then check in code behind, like so:

If FileUpload1.PostedFile.ContentLength > 2097152 Then ' (2097152 = 2 Mb)
  ' Exceeded the 2 Mb limit
  ' Do something
End If

Just make sure the [Size In Bytes] in the web.config is greater than the size of the file you wish to upload then you won't get the 404 error. You can then check the file size in code behind using the ContentLength which would be much better

http://msdn.microsoft.com/en-us/library/system.io.directory.getfiles.aspx

The System.IO namespace has loads of methods to help you with file operations. The

Directory.GetFiles() 

method returns an array of strings which represent the files in the target directory.

You cant style the alt attribute directly in css. However the alt will inherit the styles of the item the alt is on or what is inherited by its parent:

    <div style="background-color:black; height: 50px; width: 50px; color:white;">_x000D_
    <img src="ouch" alt="here i am"/>_x000D_
    <div>

In the above example, the alt text will be black. However with the color:white the alt text is white.

I had the same problem, but setting windowSoftInputMode did not help, and I did not want to change the upper view to have isScrollContainer="false" because I wanted it to scroll.

My solution was to define the top location of the navigation tools instead of the bottom. I'm using Titanium, so I'm not sure exactly how this would translate to android. Defining the top location of the navigation tools view prevented the soft keyboard from pushing it up, and instead covered the nav controls like I wanted.

SelectedText is to get or set the actual text in the string editor for the selected item in the combobox as documented here . This goes uneditable if you set:

comboBox1.DropDownStyle = System.Windows.Forms.ComboBoxStyle.DropDownList;

Use:

comboBox1.SelectedItem = "test1";

or:

comboBox1.SelectedIndex = comboBox1.Items.IndexOf("test1");

Assert is very useful when developing. You use it when something just cannot happen if your code is working correctly. It's easy to use, and can stay in the code for ever, because it will be turned off in real life.

If there is any chance that the condition can occur in real life, then you must handle it.

I love it, but don't know how to turn it on in Eclipse/Android/ADT . It seems to be off even when debugging. (There is a thread on this, but it refers to the 'Java vm', which does not appear in the ADT Run Configuration).

I prefer dotmemory from Jetbrains

I released a grep alternative a few days ago that does support this directly, either via multiline matching or using conditions - hopefully it is useful for some people searching here. This is what the commands for the example would look like:

Multiline:

sift -lm 'abc.*efg' testfile

Conditions:

sift -l 'abc' testfile --followed-by 'efg'

You could also specify that 'efg' has to follow 'abc' within a certain number of lines:

sift -l 'abc' testfile --followed-within 5:'efg'

You can find more information on sift-tool.org.

a dplyr solution using mutate_all and pipes

say you have the following:

> dft
Source: local data frame [11 x 5]

   Bureau.Name Account.Code   X2014   X2015   X2016
1       Senate          110 158,000 211,000 186,000
2       Senate          115       0       0       0
3       Senate          123  15,000  71,000  21,000
4       Senate          126   6,000  14,000   8,000
5       Senate          127 110,000 234,000 134,000
6       Senate          128 120,000 159,000 134,000

10      Senate          140       0       0       0
11      Senate          140       0       0       0

and want to remove commas from the year variables X2014-X2016, and convert them to numeric. also, let's say X2014-X2016 are read in as factors (default)

dft %>%
    mutate_all(funs(as.character(.)), X2014:X2016) %>%
    mutate_all(funs(gsub(",", "", .)), X2014:X2016) %>%
    mutate_all(funs(as.numeric(.)), X2014:X2016)

mutate_all applies the function(s) inside funs to the specified columns

I did it sequentially, one function at a time (if you use multiple functions inside funs then you create additional, unnecessary columns)

First, if you need to talk to a bluetooth 2.x device, this documentation states that :

Hint: If you are connecting to a Bluetooth serial board then try using the well-known SPP UUID 00001101-0000-1000-8000-00805F9B34FB. However if you are connecting to an Android peer then please generate your own unique UUID.

I didn't think that it would work, but only by replacing the UUID with 00001101-0000-1000-8000-00805F9B34FB it works. However, this code seems to handle the problem of SDK version, and you can just replace the function device.createRfcommSocketToServiceRecord(mMyUuid); with tmp = createBluetoothSocket(mmDevice); after defining the following method :

private BluetoothSocket createBluetoothSocket(BluetoothDevice device)
    throws IOException {
    if(Build.VERSION.SDK_INT >= 10){
        try {
            final Method m = device.getClass().getMethod("createInsecureRfcommSocketToServiceRecord", new Class[] { UUID.class });
            return (BluetoothSocket) m.invoke(device, mMyUuid);
        } catch (Exception e) {
            Log.e(TAG, "Could not create Insecure RFComm Connection",e);
        }
    }
    return  device.createRfcommSocketToServiceRecord(mMyUuid);
}

The source code isn't mine, but comes from this website.

I recommend setting an alternative location for your npm modules.

npm config set prefix C:\Dev\npm-repository\npm --global 
npm config set cache C:\Dev\npm-repository\npm-cache --global  

Of course you can set the location to wherever best suits.

This has worked well for me and gets around any permissions issues that you may encounter.

sudo ln -s /usr/bin/nodejs /usr/bin/node

or install legacy nodejs:

Here is the documentation on the drawer and it appears that you can configure it to pull out from the left or right.

Drawer positioning and layout is controlled using the android:layout_gravity attribute on child views corresponding to which side of the view you want the drawer to emerge from: left or right. (Or start/end on platform versions that support layout direction.)

http://developer.android.com/reference/android/support/v4/widget/DrawerLayout.html

Starting with @Ravi's answer, I also applied some validation rules for the NPA (Area) Code.

In particular:

• It should start with a 2 (or higher)
• It cannot have "11" as the second and third digits (N11).

There are a couple other restrictions, including reserved blocks (N9X, 37X, 96X) and 555, but I left those out, particularly because the reserved blocks may see future use, and 555 is useful for testing.

This is what I came up with:

^((\+\d{1,2}|1)[\s.-]?)?\(?[2-9](?!11)\d{2}\)?[\s.-]?\d{3}[\s.-]?\d{4}$

Alternately, if you also want to match blank values (if the field isn't required), you can use:

(^((\+\d{1,2}|1)[\s.-]?)?\(?[2-9](?!11)\d{2}\)?[\s.-]?\d{3}[\s.-]?\d{4}$|^$)

My test cases for valid numbers (many from @Francis' answer) are:

18005551234
1 800 555 1234
+1 800 555-1234
+86 800 555 1234
1-800-555-1234
1.800.555.1234
+1.800.555.1234
1 (800) 555-1234
(800)555-1234
(800) 555-1234
(800)5551234
800-555-1234
800.555.1234

My invalid test cases include:

(003) 555-1212     // Area code starts with 0
(103) 555-1212     // Area code starts with 1
(911) 555-1212     // Area code ends with 11
180055512345       // Too many digits
1 800 5555 1234    // Prefix code too long
+1 800 555x1234    // Invalid delimiter
+867 800 555 1234  // Country code too long
1-800-555-1234p    // Invalid character
1 (800)  555-1234  // Too many spaces
800x555x1234       // Invalid delimiter
86 800 555 1212    // Non-NA country code doesn't have +

My regular expression does not include grouping to extract the digit groups, but it can be modified to include those.

Here is a query which you can use to search for anything in from your database as a search result ,

SELECT * FROM tbl_customer 
    WHERE CustomerName LIKE '%".$search."%'
    OR Address LIKE '%".$search."%' 
    OR City LIKE '%".$search."%' 
    OR PostalCode LIKE '%".$search."%' 
    OR Country LIKE '%".$search."%'

Using this code will help you search in for multiple columns easily

From @Erik Hunter, I post full code for make horizontal UICollectionView

UICollectionViewFlowLayout *collectionViewFlowLayout = [[UICollectionViewFlowLayout alloc] init];
[collectionViewFlowLayout setScrollDirection:UICollectionViewScrollDirectionHorizontal];
self.myCollectionView.collectionViewLayout = collectionViewFlowLayout;

In Swift

let layout = UICollectionViewFlowLayout()
layout.scrollDirection = .Horizontal
self.myCollectionView.collectionViewLayout = layout

In Swift 3.0

let layout = UICollectionViewFlowLayout()
layout.scrollDirection = .horizontal
self.myCollectionView.collectionViewLayout = layout

Hope this help

Here are two extension methods you can use. They ensure any existing classes are preserved and do not duplicate classes being added.

public static void RemoveCssClass(this WebControl control, String css) {
  control.CssClass = String.Join(" ", control.CssClass.Split(' ').Where(x => x != css).ToArray());
}

public static void AddCssClass(this WebControl control, String css) {
  control.RemoveCssClass(css);
  css += " " + control.CssClass;
  control.CssClass = css;
}

Usage: hlCreateNew.AddCssClass("disabled");

Usage: hlCreateNew.RemoveCssClass("disabled");

Well yea, they are the same, but....!

window.location is not working on some Internet Explorer browsers.

you try this way

const fetchBusinesses = () => {
    return fetch("theURL", {method: "GET"}
    )
      .then(res => normalizeResponseErrors(res))
      .then(res => {
        return res.json();
      })
      .then(rcvdBusinesses => {
        // some stuff
      })
      .catch(err => {
        // some error handling
      });
  };

and

useEffect(() => {
    fetchBusinesses();
  });

it's work for you. But my suggestion is try this way also work for you. It's better than before way. I use this way:

useEffect(() => {
        const fetchBusinesses = () => {
    return fetch("theURL", {method: "GET"}
    )
      .then(res => normalizeResponseErrors(res))
      .then(res => {
        return res.json();
      })
      .then(rcvdBusinesses => {
        // some stuff
      })
      .catch(err => {
        // some error handling
      });
  };
        fetchBusinesses();
      }, []);

if you get data on the base of specific id then add in callback useEffect [id] then cannot show you warning React Hook useEffect has a missing dependency: 'any thing'. Either include it or remove the dependency array

Nothing printed. The argument must be a pointer to a signed int, where the number of characters written so far is stored.

#include <stdio.h>

int main()
{
  int val;

  printf("blah %n blah\n", &val);

  printf("val = %d\n", val);

  return 0;

}

The previous code prints:

blah  blah
val = 5

Use the command:

git rev-parse HEAD

For the short version:

git rev-parse --short HEAD

I know it is an old thread, but recently I needed the same and found a neat way:

SELECT c.name FROM pragma_table_info('your_table_name') c;

The second parameter of findBy is for ORDER.

$ens = $em->getRepository('AcmeBinBundle:Marks')
          ->findBy(
             array('type'=> 'C12'), 
             array('id' => 'ASC')
           );

Similar to Java in PHP only set Select PARAMETER with value 'COUNT'

$result = $aws->query(array(
 'TableName' => 'game_table',
 'IndexName' => 'week-point-index',
 'KeyConditions' => array(
    'week' => array(
        'ComparisonOperator' => 'EQ',
        'AttributeValueList' => array(
            array(Type::STRING => $week)
        )
    ),
    'point' => array(
        'ComparisonOperator' => 'GE',
        'AttributeValueList' => array(
            array(Type::NUMBER => $my_point)
        )
    )
 ),
 'Select' => 'COUNT'
));

and acces it just like this :

echo $result['Count'];

but as Saumitra mentioned above be careful with resultsets largers than 1 MB, in that case use LastEvaluatedKey til it returns null to get the last updated count value.

man 8 pam_env

man 5 pam_env.conf

If all login services use PAM, and all login services have session required pam_env.so in their respective /etc/pam.d/* configuration files, then all login sessions will have some environment variables set as specified in pam_env's configuration file.

On most modern Linux distributions, this is all there by default -- just add your desired global environment variables to /etc/security/pam_env.conf.

This works regardless of the user's shell, and works for graphical logins too (if xdm/kdm/gdm/entrance/… is set up like this).

Assuming you type in the full path to the bash script, use $0 and dirname, e.g.:

#!/bin/bash
echo "$0"
dirname "$0"

Example output:

$ /a/b/c/myScript.bash
/a/b/c/myScript.bash
/a/b/c

If necessary, append the results of the $PWD variable to a relative path.

EDIT: Added quotation marks to handle space characters.

Here is a solution that guarantees entire file will be read, that requires no libraries and is efficient:

byte[] fullyReadFileToBytes(File f) throws IOException {
    int size = (int) f.length();
    byte bytes[] = new byte[size];
    byte tmpBuff[] = new byte[size];
    FileInputStream fis= new FileInputStream(f);;
    try {

        int read = fis.read(bytes, 0, size);
        if (read < size) {
            int remain = size - read;
            while (remain > 0) {
                read = fis.read(tmpBuff, 0, remain);
                System.arraycopy(tmpBuff, 0, bytes, size - remain, read);
                remain -= read;
            }
        }
    }  catch (IOException e){
        throw e;
    } finally {
        fis.close();
    }

    return bytes;
}

NOTE: it assumes file size is less than MAX_INT bytes, you can add handling for that if you want.

If you check Thrown for Common Language Runtime Exception in the break when an exception window (Ctrl+Alt+E in Visual Studio), then the execution should break while you are debugging when the exception is thrown.

This will probably give you some insight into what is going on.

These guys have an API that will give the results. It's also free to use.

Note: they also provide data source download in xls or sql format at a premium price. but these data also provides technical specifications for all the make model and trim options.

If you're looking to do an "upsert" one of the most efficient ways currently in SQL Server for single rows is this:

UPDATE myTable ...


IF @@ROWCOUNT=0
    INSERT INTO myTable ....

You can also use the MERGE syntax if you're doing this with sets of data rather than single rows.

If you want to INSERT and not UPDATE then you can just write your single INSERT statement and use WHERE NOT EXISTS (SELECT ...)

Here is my step by step experience, inspired by typeahead examples, from a Scala/PlayFramework app we are working on.

In a script LearnerNameTypeAhead.coffee (convertible of course to JS) I have:

$ ->
  learners = new Bloodhound(
    datumTokenizer: Bloodhound.tokenizers.obj.whitespace("value")
    queryTokenizer: Bloodhound.tokenizers.whitespace
    remote: "/learner/namelike?nameLikeStr=%QUERY"
  )
  learners.initialize()
  $("#firstName").typeahead 
    minLength: 3
    hint: true
    highlight:true
   ,
    name: "learners"
    displayKey: "value"
    source: learners.ttAdapter()

I included the typeahead bundle and my script on the page, and there is a div around my input field as follows:

<script [email protected]("javascripts/typeahead.bundle.js")></script>
<script [email protected]("javascripts/LearnerNameTypeAhead.js") type="text/javascript" ></script>
<div>
  <input name="firstName" id="firstName" class="typeahead" placeholder="First Name" value="@firstName">
</div>

The result is that for each character typed in the input field after the first minLength (3) characters, the page issues a GET request with a URL looking like /learner/namelike?nameLikeStr= plus the currently typed characters. The server code returns a json array of objects containing fields "id" and "value", for example like this:

[ {
    "id": "109",
    "value": "Graham Jones"
  },
  {
    "id": "5833",
    "value": "Hezekiah Jones"
} ]

For play I need something in the routes file:

GET /learner/namelike controllers.Learners.namesLike(nameLikeStr:String)

And finally, I set some of the styling for the dropdown, etc. in a new typeahead.css file which I included in the page's <head> (or accessible .css)

Not in the RFC, no, but there are practical limits.

The HTTP protocol does not place any a priori limit on the length of a URI. Servers MUST be able to handle the URI of any resource they serve, and SHOULD be able to handle URIs of unbounded length if they provide GET-based forms that could generate such URIs. A server SHOULD return 414 (Request-URI Too Long) status if a URI is longer than the server can handle (see section 10.4.15).

Note: Servers should be cautious about depending on URI lengths above 255 bytes, because some older client or proxy implementations may not properly support these lengths.

For Transaction in database level

mostly I used @Transactional in DAO's just on method level, so configuration can be specifically for a method / using default (required)

1. DAO's method that get data fetch (select .. ) - don't need @Transactional this can lead to some overhead because of transaction interceptor / and AOP proxy that need to be executed as well.

2. DAO's methods that do insert / update will get @Transactional

very good blog on transctional

For application level -
I am using transactional for business logic I would like to be able rolback in case of unexpected error

@Transactional(rollbackFor={MyApplicationException.class})
public void myMethod(){

    try {    
        //service logic here     
    } catch(Throwable e) {

        log.error(e)
        throw new MyApplicationException(..);
    }
}

You did not include the datepicker library

so add

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.11/jquery-ui.min.js"></script>

to your <head> tag

live demo

If you want to access your page's global variables, you can do so:

@{
    ViewData["Title"] = "Home Page";

    var LoadingButtons = Model.ToDictionary(person => person, person => false);

    string GetLoadingState (string person) => LoadingButtons[person] ? "is-loading" : string.Empty;
}

For some reason @Alejandro Gracia answer starts working only after a few second. I found a solution that blocks the RecyclerView instantaneously:

recyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
            @Override
            public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
                return true;
            }
            @Override
            public void onTouchEvent(RecyclerView rv, MotionEvent e) {
            }
            @Override
            public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
            }
        });

attachedCompanyIDs is one big string, so mysql try to find company in this its cast to integer

when you use where in

so if comapnyid = 1 :

companyID IN ('1,2,3')

this is return true

but if the number 1 is not in the first place

 companyID IN ('2,3,1')

its return false

Remove the display:none, and use ng-show instead:

<ul class="procedures">
    <li ng-repeat="procedure in procedures | filter:query | orderBy:orderProp">
        <h4><a href="#" ng-click="showDetails = ! showDetails">{{procedure.definition}}</a></h4>
         <div class="procedure-details" ng-show="showDetails">
            <p>Number of patient discharges: {{procedure.discharges}}</p>
            <p>Average amount covered by Medicare: {{procedure.covered}}</p>
            <p>Average total payments: {{procedure.payments}}</p>
         </div>
    </li>
</ul>

Here's the fiddle: http://jsfiddle.net/asmKj/

You can also use ng-class to toggle a class:

<div class="procedure-details" ng-class="{ 'hidden': ! showDetails }">

I like this more, since it allows you to do some nice transitions: http://jsfiddle.net/asmKj/1/

If you are using a build tool then try Rucksack.

Otherwise, you can use CSS variables (custom properties) to easily control the minimum and maximum font sizes like so (demo):

* {
  /* Calculation */
  --diff: calc(var(--max-size) - var(--min-size));
  --responsive: calc((var(--min-size) * 1px) + var(--diff) * ((100vw - 420px) / (1200 - 420))); /* Ranges from 421px to 1199px */
}

h1 {
  --max-size: 50;
  --min-size: 25;
  font-size: var(--responsive);
}

h2 {
  --max-size: 40;
  --min-size: 20;
  font-size: var(--responsive);
}

You should add reference to "Microsoft.AspNet.WebApi.Client" package (read this article for samples).

Without any additional extension, you may use standard PostAsync method:

client.PostAsync(uri, new StringContent(jsonInString, Encoding.UTF8, "application/json"));

where jsonInString value you can get by calling JsonConvert.SerializeObject(<your object>);

I don't think it is possible, because function definitions do not match in your example.

Your lambda expression is evaluated exactly as

void action() { }

whereas your declaration looks like

Void action(Void v) {
    //must return Void type.
}

as an example, if you have following interface

public interface VoidInterface {
    public Void action(Void v);
}

the only kind of function (while instantiating) that will be compatibile looks like

new VoidInterface() {
    public Void action(Void v) {
        //do something
        return v;
    }
}

and either lack of return statement or argument will give you a compiler error.

Therefore, if you declare a function which takes an argument and returns one, I think it is impossible to convert it to function which does neither of mentioned above.

I know that the question is too old, anyway:

select a, b from mytable group by a, b

will give your all the combinations.

That's the non-null assertion operator. It is a way to tell the compiler "this expression cannot be null or undefined here, so don't complain about the possibility of it being null or undefined." Sometimes the type checker is unable to make that determination itself.

It is explained here:

A new ! post-fix expression operator may be used to assert that its operand is non-null and non-undefined in contexts where the type checker is unable to conclude that fact. Specifically, the operation x! produces a value of the type of x with null and undefined excluded. Similar to type assertions of the forms <T>x and x as T, the ! non-null assertion operator is simply removed in the emitted JavaScript code.

I find the use of the term "assert" a bit misleading in that explanation. It is "assert" in the sense that the developer is asserting it, not in the sense that a test is going to be performed. The last line indeed indicates that it results in no JavaScript code being emitted.

This is my android:layout_height=50% activity:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

        style="@style/loginType"
        android:background="#27b" >
    </LinearLayout>

    <LinearLayout
        android:id="@+id/taobao_login"
        style="@style/loginType"
        android:background="#ed6d00" >

    <item name="android:layout_height">match_parent</item>
    <item name="android:layout_weight">0.5</item>
    <item name="android:orientation">vertical</item>
</style>

On terminal type mvn -v and the output will look like the image shown below

If you want to delete all records then as a workaround load an empty file into table in OVERWRITE mode

hive> LOAD DATA LOCAL INPATH '/root/hadoop/textfiles/empty.txt' OVERWRITE INTO TABLE employee;
Loading data to table default.employee
Table default.employee stats: [numFiles=1, numRows=0, totalSize=0, rawDataSize=0]
OK
Time taken: 0.19 seconds

hive> SELECT * FROM employee;
OK
Time taken: 0.052 seconds

You can set any scale you wish. It`s became actual after 6+ simulator been presented

To obtain it follow next easy steps:

1. quit simulator if open
2. open terminal (from spotlight for example)
3. paste next text to terminal and press enter

defaults write ~/Library/Preferences/com.apple.iphonesimulator SimulatorWindowLastScale "0.4"

You can try any scales changing 0.4 to desired value.

To reset this custom scale, just apply any standard scale from simulator menu in way described above.

Use Console.ReadLine() at the end of the program. This will keep the window open until you press the Enter key. See https://docs.microsoft.com/en-us/dotnet/api/system.console.readline for details.

I faced this issue, and resolved this issue using getchar() to catch the ('\n') new char

slice works just fine in IE and other browsers, it's part of the specification and it's the most efficient method too:

alert("xxx_456".slice(-3));
//-> 456

The columns in the result set of a select query with group by clause must be:

• an expression used as one of the group by criteria , or ...
• an aggregate function , or ...
• a literal value

So, you can't do what you want to do in a single, simple query. The first thing to do is state your problem statement in a clear way, something like:

I want to find the individual claim row bearing the most recent creation date within each group in my claims table

Given

create table dbo.some_claims_table
(
  claim_id     int      not null ,
  group_id     int      not null ,
  date_created datetime not null ,

  constraint some_table_PK primary key ( claim_id                ) ,
  constraint some_table_AK01 unique    ( group_id , claim_id     ) ,
  constraint some_Table_AK02 unique    ( group_id , date_created ) ,

)

The first thing to do is identify the most recent creation date for each group:

select group_id ,
       date_created = max( date_created )
from dbo.claims_table
group by group_id

That gives you the selection criteria you need (1 row per group, with 2 columns: group_id and the highwater created date) to fullfill the 1st part of the requirement (selecting the individual row from each group. That needs to be a virtual table in your final select query:

select *
from dbo.claims_table t
join ( select group_id ,
       date_created = max( date_created )
       from dbo.claims_table
       group by group_id
      ) x on x.group_id     = t.group_id
         and x.date_created = t.date_created

If the table is not unique by date_created within group_id (AK02), you you can get duplicate rows for a given group.

I had the same problem of the html data tag not updating when i was using jquery But changing the code that does the actual work from jquery to javascript worked.

Try using this when the button is clicked: (Note that the main code is Javascripts setAttribute() function.)

function increment(q) {

    //increment current num by adding with 1
    q = q+1;

    //change data attribute using JS setAttribute function
    div.setAttribute('data-num',q);

    //refresh data-num value (get data-num value again using JS getAttribute function)
    num = parseInt(div.getAttribute('data-num'));

    //show values
    console.log("(After Increment) Current Num: "+num);

}

//get variables, set as global vars
var div = document.getElementById('foo');
var num = parseInt(div.getAttribute('data-num'));

//increment values using click
$("#changeData").on('click',function(){

    //pass current data-num as parameter
    increment(num);

});

Use coord_flip()

data(diamonds)
diamonds$cut <- paste("Super Dee-Duper",as.character(diamonds$cut))

qplot(cut, carat, data = diamonds, geom = "boxplot") +
  coord_flip()

Add str_wrap()

# wrap text to no more than 15 spaces
library(stringr)
diamonds$cut2 <- str_wrap(diamonds$cut, width = 15)
qplot(cut2, carat, data = diamonds, geom = "boxplot") +
  coord_flip()

In Ch 3.9 of R for Data Science, Wickham and Grolemund speak to this exact question:

coord_flip() switches the x and y axes. This is useful (for example), if you want horizontal boxplots. It’s also useful for long labels: it’s hard to get them to fit without overlapping on the x-axis.

You could write an extension method (for what it's worth):

public static string EmptyNull(this string str)
{
    return str ?? "";
}

Now this works safely:

string str = null;
string upper = str.EmptyNull().ToUpper();

WebDriver driver = new FirefoxDriver();

Actions action = new Actions(driver); 

action.keyDown(Keys.CONTROL).sendKeys("a").keyUp(Keys.CONTROL).perform();

This method removes the extra call ( String.ValueOf() ) to convert unicode to string.

There are a few options

Short Syntax

Using the host : guest format you can do any of the following:

volumes:
  # Just specify a path and let the Engine create a volume
  - /var/lib/mysql

  # Specify an absolute path mapping
  - /opt/data:/var/lib/mysql

  # Path on the host, relative to the Compose file
  - ./cache:/tmp/cache

  # User-relative path
  - ~/configs:/etc/configs/:ro

  # Named volume
  - datavolume:/var/lib/mysql

Long Syntax

As of docker-compose v3.2 you can use long syntax which allows the configuration of additional fields that can be expressed in the short form such as mount type (volume, bind or tmpfs) and read_only.

version: "3.2"
services:
  web:
    image: nginx:alpine
    ports:
      - "80:80"
    volumes:
      - type: volume
        source: mydata
        target: /data
        volume:
          nocopy: true
      - type: bind
        source: ./static
        target: /opt/app/static

Regarding whitehawk's accepted answer. I am just trying to add a bit hands on experience. Was just trying to add a comments, but SO complains it's too long.

Basically, without IE 9 installed, the registry switch FEATURE_BROWSER_EMULATION won't work AT ALL.

For example, my own experience today I was trying to get the .net webcontrol to work with IE10 mode because one html I am trying to render won't work with .netControl under VS2012, and not even work when I load the html to IE8 directly, still css won't render properly(even after I say allow blocked content). But I have tested the same html ok with IE10 on a friend's win 8 machine. That's why I am trying to set the .net webControl to IE 10 mode but just keeps failing...

Now I figured this is bcos my win 7 machine only have IE8 installed, so regardless which value I set to the FEATURE_BROWSER_EMULATION switch(value to IE9, IE10 IE11), it just won't work AT ALL !

Then I downloaded and installed IE 10 on my win 7 machine. Still it won't work, then I added the FEATURE_BROWSER_EMULATION, it started working !

Also I noticed regardless which value I set , even set it to value 0 by default, the webControl is still using IE 10 mode which still works for me.

So to summarise, If you have IE X installed but you want your .Net webControl to work under IE (X+N) N>0 modo, TWO things you need to do:

1. Go to MS website & download and install IE (X+N) on your machine, you will need to reboot after installation.

2. apply whitehawk's answer.

Basically: To control the value of this feature by using the registry, add the name of your executable file to the following setting and set the value to match the desired setting.

HKEY_LOCAL_MACHINE (or HKEY_CURRENT_USER)
   SOFTWARE
      Microsoft
         Internet Explorer
            Main
               FeatureControl
                  FEATURE_BROWSER_EMULATION
                     contoso.exe = (DWORD) 00009000

Windows Internet Explorer 8 and later. The FEATURE_BROWSER_EMULATION feature defines the default emulation mode for Internet Explorer and supports the following values.

Value Description

• 11001 (0x2AF9 Internet Explorer 11. Webpages are displayed in IE11 edge mode, regardless of the !DOCTYPE directive.

  11000 (0x2AF8) IE11. Webpages containing standards-based !DOCTYPE directives are displayed in IE11 edge mode. Default value for IE11.

  10001 (0x2711) Internet Explorer 10. Webpages are displayed in IE10 Standards mode, regardless of the !DOCTYPE directive.

  10000 (0x02710) Internet Explorer 10. Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode. Default value for Internet Explorer 10.

I had this error, because of a missing closing parenthesis on a line.

I started off having an issue with a line saying: invalid syntax (<string>, line ...)? at the end of my script.

I deleted that line, then got the EOF message.

All the above solutions doesn't seem to work in 2019 with the latest Android Studio 3.4+.

I figured out a perfect and up to date solution to migrate or upgrade your Android Project to Java 8.

Solution: Click on File -> Project Structure -> Modules -> Properties tab.

Change the Source Compatibility and Target Compatibility to 1.8 (Java 8)

Another possible solution is instead of passing a variable number of arguments to a stored procedure, pass a single string containing the names you're after, but make them unique by surrounding them with '<>'. Then use PATINDEX to find the names:

SELECT * 
FROM Tags 
WHERE PATINDEX('%<' + Name + '>%','<jo>,<john>,<scruffy>,<rubyonrails>') > 0

Java is strongly typed. 0 and 1 are numbers, which is a different type than a boolean. A number will never be equal to a boolean.

If you want to suppress the warnings and some other error types (for example, notices) while displaying all other errors, you can do:

error_reporting(E_ALL & ~E_WARNING & ~E_NOTICE);

The same thing happened to me. I wanted to open the Bootstrap modal by clicking on the table rows and get more details about each row. I used a trick to do this, Which I call the virtual button! Compatible with the latest version of Bootstrap (v5.0.0-alpha2). It might be useful for others as well.

See this code snippet with preview: https://gist.github.com/alireza-rezaee/c60da1429c36351ef4f071dec0ea9aba

Summary:

let exampleButton = document.createElement("button");
exampleButton.classList.add("d-none");
document.body.appendChild(exampleButton);
exampleButton.dataset.toggle = "modal";
exampleButton.dataset.target = "#exampleModal";

//AddEventListener to all rows
document.querySelectorAll('#exampleTable tr').forEach(row => {
    row.addEventListener('click', e => {
        //Set parameteres (clone row dataset)
        exampleButton.dataset.whatever = e.target.closest('tr').dataset.whatever;
        //Button click simulation
        //Now we can use relatedTarget
        exampleButton.click();
    })
});

All this is to use the relatedTarget property. (See Bootstrap docs)

The only secure way of doing this

The only guaranteed secure method of retrieving the current domain is to store it in a secure location yourself.

Most frameworks take care of storing the domain for you, so you will want to consult the documentation for your particular framework. If you're not using a framework, consider storing the domain in one of the following places:

The following work... but they're not secure

Hackers can make the following variables output whatever domain they want. This can lead to cache poisoning and barely noticeable phishing attacks.

$_SERVER['HTTP_HOST']

This gets the domain from the request headers which are open to manipulation by hackers. Same with:

$_SERVER['SERVER_NAME']

This one can be made better if the Apache setting usecanonicalname is turned off; in which case $_SERVER['SERVER_NAME'] will no longer be allowed to be populated with arbitrary values and will be secure. This is, however, non-default and not as common of a setup.

In popular systems

Below is how you can get the current domain in the following frameworks/systems:

WordPress

$urlparts = parse_url(home_url());
$domain = $urlparts['host'];

If you're constructing a URL in WordPress, just use home_url or site_url, or any of the other URL functions.

Laravel

request()->getHost()

The request()->getHost function is inherited from Symfony, and has been secure since the 2013 CVE-2013-4752 was patched.

Drupal

The installer does not yet take care of making this secure (issue #2404259). But in Drupal 8 there is documentation you can you can follow at Trusted Host Settings to secure your Drupal installation after which the following can be used:

\Drupal::request()->getHost();

Other frameworks

Feel free to edit this answer to include how to get the current domain in your favorite framework. When doing so, please include a link to the relevant source code or to anything else that would help me verify that the framework is doing things securely.

Addendum

Exploitation examples:

1. Cache poisoning can happen if a botnet continuously requests a page using the wrong hosts header. The resulting HTML will then include links to the attackers website where they can phish your users. At first the malicious links will only be sent back to the hacker, but if the hacker does enough requests, the malicious version of the page will end up in your cache where it will be distributed to other users.

2. A phishing attack can happen if you store links in the database based on the hosts header. For example, let say you store the absolute URL to a user's profiles on a forum. By using the wrong header, a hacker could get anyone who clicks on their profile link to be sent a phishing site.

3. Password reset poisoning can happen if a hacker uses a malicious hosts header when filling out the password reset form for a different user. That user will then get an email containing a password reset link that leads to a phishing site. Another more complex form of this skips the user having to do anything by getting the email to bounce and resend to one of the hacker's SMTP servers (for example CVE-2017-8295.)

4. Here are some more malicious examples

Additional Caveats and Notes:

• When usecanonicalname is turned off the $_SERVER['SERVER_NAME'] is populated with the same header $_SERVER['HTTP_HOST'] would have used anyways (plus the port). This is Apache's default setup. If you or devops turns this on then you're okay -- ish -- but do you really want to rely on a separate team, or yourself three years in the future, to keep what would appear to be a minor configuration at a non-default value? Even though this makes things secure, I would caution against relying on this setup.
• Redhat, however, does turn usecanonical on by default [source].
• If serverAlias is used in the virtual hosts entry, and the aliased domain is requested, $_SERVER['SERVER_NAME'] will not return the current domain, but will return the value of the serverName directive.
• If the serverName cannot be resolved, the operating system's hostname command is used in its place [source].
• If the host header is left out, the server will behave as if usecanonical was on [source].
• Lastly, I just tried exploiting this on my local server, and was unable to spoof the hosts header. I'm not sure if there was an update to Apache that addressed this, or if I was just doing something wrong. Regardless, this header would still be exploitable in environments where virtual hosts are not being used.

Little Rant:

     This question received hundreds of thousands of views without a single mention of the security problems at hand! It shouldn't be this way, but just because a Stack Overflow answer is popular, that doesn't mean it is secure.

Why do you want to reinvent the wheel when there are opensource that are already doing the job pretty nicely.

Both apache common-langs and spring support some very flexible builder pattern

For apache, here is how you do it reflectively

@Override
public String toString()
{
  return ToStringBuilder.reflectionToString(this);
}

Here is how you do it if you only want to print fields that you care about.

@Override
public String toString() 
{
    return new ToStringBuilder(this)
      .append("name", name)
      .append("location", location)
      .append("address", address)
      .toString(); 
}

You can go as far as "styling" your print output with non-default ToStringStyle or even customizing it with your own style.

I didn't personally try spring ToStringCreator api, but it looks very similar.

when the port was used by another program.

we also have had similar problems (we're behind a corporate proxy). changing to yarn at least on our jenkins builds made a huge difference.

there are some minor differences in the results between "npm install" and "yarn install" - but nothing that hurts us.

Simple solution using the itertools and string modules

# modules to easily set characters and iterate over them
import itertools, string 

# character limit so you don't run out of ram
maxChar = int(input('Character limit for password: '))  

# file to save output to, so you can look over the output without using so much ram
output_file = open('insert filepath here', 'a+') 

# this is the part that actually iterates over the valid characters, and stops at the 
# character limit.
x = list(map(''.join, itertools.permutations(string.ascii_lowercase, maxChar))) 

# writes the output of the above line to a file 
output_file.write(str(x)) 

# saves the output to the file and closes it to preserve ram
output_file.close() 

I piped the output to a file to save ram, and used the input function so you can set the character limit to something like "hiiworld". Below is the same script but with a more fluid character set using letters, numbers, symbols, and spaces.

import itertools, string

maxChar = int(input('Character limit for password: '))
output_file = open('insert filepath here', 'a+')

x = list(map(''.join, itertools.permutations(string.printable, maxChar)))
x.write(str(x))
x.close()

WORKER TIMEOUT means your application cannot response to the request in a defined amount of time. You can set this using gunicorn timeout settings. Some application need more time to response than another.

Another thing that may affect this is choosing the worker type

The default synchronous workers assume that your application is resource-bound in terms of CPU and network bandwidth. Generally this means that your application shouldn’t do anything that takes an undefined amount of time. An example of something that takes an undefined amount of time is a request to the internet. At some point the external network will fail in such a way that clients will pile up on your servers. So, in this sense, any web application which makes outgoing requests to APIs will benefit from an asynchronous worker.

When I got the same problem as yours (I was trying to deploy my application using Docker Swarm), I've tried to increase the timeout and using another type of worker class. But all failed.

And then I suddenly realised I was limitting my resource too low for the service inside my compose file. This is the thing slowed down the application in my case

deploy:
  replicas: 5
  resources:
    limits:
      cpus: "0.1"
      memory: 50M
  restart_policy:
    condition: on-failure

So I suggest you to check what thing slowing down your application in the first place

As it has been explained here, beside of multiple extensions that perform ad or script blocking you may aware that this may happen by file names as below:

Particularly in the AdBlock Plus the character string "-300x600" is causing the Failed to Load Resource ERR_BLOCKED_BY_CLIENT problem.

As shown in the picture, some of the images were blocked because of the '-300x600' pattern in their name, that particular text pattern matches an expression list pattern in the AdBlock Plus.

MySQL said: Documentation #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'TYPE=MyISAM' at line 36

ActiveXObject is available only on IE browser. So every other useragent will throw an error

On modern browser you could use instead File API or File writer API (currently implemented only on Chrome)

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

val testDataFrame = Seq(
  (1.0, 4.0), (2.0, 5.0), (3.0, 6.0)
).toDF("A", "B")

val (maxA, maxB) = testDataFrame.select(max("A"), max("B"))
  .as[(Double, Double)]
  .first()
println(maxA, maxB)

And the result is (3.0,6.0), which is the same to the testDataFrame.agg(max($"A"), max($"B")).collect()(0).However, testDataFrame.agg(max($"A"), max($"B")).collect()(0) returns a List, [3.0,6.0]

radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
       @Override
       public void onCheckedChanged(RadioGroup group, int checkedId)
       {
           radioButton = (RadioButton) findViewById(checkedId);
           Toast.makeText(getBaseContext(), radioButton.getText(), Toast.LENGTH_SHORT).show();
       }
   }
   );

What you need to remember is that when using LINQ you are utilizing delayed execution. The other methods described here all work perfectly, but they are executed immediately. Furthermore the Concat() function is probably optimized in ways you can't do yourself (calls to internal API's, OS calls etc.). Anyway, unless you really need to try and optimize, you're currently on your path to "the root of all evil" ;)

... and so you should do something like this:

set(tuple ((a,b) for a in range(3)) for b in range(3))

... and if needed convert back to list

You can always use an attribute selector. The selector itself would look something like:

a[data-item-id=stand-out]

If the above solution didn't work for you, you can use import { withRouter } from 'react-router-dom';

Using this you can export your child class as -

class MyApp extends Component{
    // your code
}

export default withRouter(MyApp);

And your class with Router -

// your code
<Router>
      ...
      <Route path="/myapp" component={MyApp} />
      // or if you are sending additional fields
      <Route path="/myapp" component={() =><MyApp process={...} />} />
<Router>

Suppose I have numbers 1 to 10 in cells A2:A11 with my autofilter in A1. I now filter to only show numbers greater then 5 (i.e. 6, 7, 8, 9, 10).

This code will only print visible cells:

Sub SpecialLoop()
    Dim cl As Range, rng As Range

    Set rng = Range("A2:A11")

    For Each cl In rng
        If cl.EntireRow.Hidden = False Then //Use Hidden property to check if filtered or not
            Debug.Print cl
        End If
    Next

End Sub

Perhaps there is a better way with SpecialCells but the above worked for me in Excel 2003.

EDIT

Just found a better way with SpecialCells:

Sub SpecialLoop()
    Dim cl As Range, rng As Range

    Set rng = Range("A2:A11")

    For Each cl In rng.SpecialCells(xlCellTypeVisible)
        Debug.Print cl
    Next cl

End Sub

you can use below groovy code for maps with foreachloop

def map=[key1:'value1',key2:'value2']

for(item in map)
{
log.info item.value // this will print value1 value2
log.info item // this will print key1=value1 key2=value2
}

Just use mysql's DATE function:

mysql> select DATE(mytimestamp) from foo;

It also works with almost any version of Visual Studio, you just need to change the "8.0" in the registry key to the appropriate version number for your version of Visual Studio.

The guide line shows up in the Output window too. (Visual Studio 2010 corrects this, and the line only shows up in the code editor window.)

You can also have the guide in multiple columns by listing more than one number after the color specifier:

RGB(230,230,230), 4, 80

Puts a white line at column 4 and column 80. This should be the value of a string value Guides in "Text Editor" key (see bellow).

Be sure to pick a line color that will be visisble on your background. This color won't show up on the default background color in VS. This is the value for a light grey: RGB(221, 221, 221).

Here are the registry keys that I know of:

Visual Studio 2010: HKCU\Software\Microsoft\VisualStudio\10.0\Text Editor

Visual Studio 2008: HKCU\Software\Microsoft\VisualStudio\9.0\Text Editor

Visual Studio 2005: HKCU\Software\Microsoft\VisualStudio\8.0\Text Editor

Visual Studio 2003: HKCU\Software\Microsoft\VisualStudio\7.1\Text Editor

For those running Visual Studio 2010, you may want to install the following extensions rather than changing the registry yourself:

• http://visualstudiogallery.msdn.microsoft.com/en-us/0fbf2878-e678-4577-9fdb-9030389b338c

• http://visualstudiogallery.msdn.microsoft.com/en-us/7f2a6727-2993-4c1d-8f58-ae24df14ea91

These are also part of the Productivity Power Tools, which includes many other very useful extensions.

Subtract -2 or -3 basis of removing last space also.

 public static void main(String[] args) {
        String s = "apple car 05";
        System.out.println(s.substring(0, s.length() - 2));
    }

Output

apple car

There is some confusion when using pip install in Windows. The instructions talk about a specific folder which has youtube-dl.exe. There is no such folder if you use pip install.

The solution is to:

• Download one of the builds from https://ffmpeg.zeranoe.com/
• Extract the zip contents
• Place the contents of the bin folder (there are three exe files) in any folder which is a path in Windows. I personally use Ananconda, so I placed them in /Anaconda/Scripts, but you could place it in any folder and add that folder to the path.

First, convert your ButtonField or CommandField to a TemplateField, then bind the Visible property of the button to a method that implements the business logic:

<asp:GridView runat="server" ID="GV1" AutoGenerateColumns="false">
    <Columns>
        <asp:BoundField DataField="Name" HeaderText="Name" />
        <asp:BoundField DataField="Age" HeaderText="Age" />
        <asp:TemplateField>
            <ItemTemplate>
                <asp:Button runat="server" Text="Reject" 
                Visible='<%# IsOverAgeLimit((Decimal)Eval("Age")) %>' 
                CommandName="Select"/>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

Then, in the code behind, add in the method:

protected Boolean IsOverAgeLimit(Decimal Age) {
    return Age > 35M;
}

The advantage here is you can test the IsOverAgeLimit method fairly easily.

use className->function(); instead className::function() ;

Asked and answered before...

Books on line says "COUNT ( { [ [ ALL | DISTINCT ] expression ] | * } )"

"1" is a non-null expression so it's the same as COUNT(*). The optimiser recognises it as trivial so gives the same plan. A PK is unique and non-null (in SQL Server at least) so COUNT(PK) = COUNT(*)

This is a similar myth to EXISTS (SELECT * ... or EXISTS (SELECT 1 ...

And see the ANSI 92 spec, section 6.5, General Rules, case 1

        a) If COUNT(*) is specified, then the result is the cardinality
          of T.

        b) Otherwise, let TX be the single-column table that is the
          result of applying the <value expression> to each row of T
          and eliminating null values. If one or more null values are
          eliminated, then a completion condition is raised: warning-
          null value eliminated in set function.

There are two basic kinds of recursions: head recursion and tail recursion.

In head recursion, a function makes its recursive call and then performs some more calculations, maybe using the result of the recursive call, for example.

In a tail recursive function, all calculations happen first and the recursive call is the last thing that happens.

If you want to insert a raw HTML string no matter how complex, you can use: insertAdjacentHTML, with appropriate first argument:

'beforebegin' Before the element itself. 'afterbegin' Just inside the element, before its first child. 'beforeend' Just inside the element, after its last child. 'afterend' After the element itself.

Hint: you can always call Element.outerHTML to get the HTML string representing the element to be inserted.

An example of usage:

document.getElementById("foo").insertAdjacentHTML("beforeBegin",
          "<div><h1>I</h1><h2>was</h2><h3>inserted</h3></div>");

DEMO

Caution: insertAdjacentHTML does not preserve listeners that where attached with .addEventLisntener.

You need to create a set of escaped (with \) parentheses (that match the parentheses) and a group of regular parentheses that create your capturing group:

var regExp = /\(([^)]+)\)/;_x000D_
var matches = regExp.exec("I expect five hundred dollars ($500).");_x000D_
_x000D_
//matches[1] contains the value between the parentheses_x000D_
console.log(matches[1]);

Breakdown:

• \( : match an opening parentheses
• ( : begin capturing group
• [^)]+: match one or more non ) characters
• ) : end capturing group
• \) : match closing parentheses

Here is a visual explanation on RegExplained

You should put the input for the last name into the same div where you have the first name.

<div>
    <label for="username">First Name</label>
    <input id="user_first_name" name="user[first_name]" size="30" type="text" />
    <input id="user_last_name" name="user[last_name]" size="30" type="text" />
</div>

Then, in your CSS give your #user_first_name and #user_last_name height and float them both to the left. For example:

#user_first_name{
    max-width:100px; /*max-width for responsiveness*/
    float:left;
}

#user_lastname_name{
    max-width:100px;
    float:left;
}

There's no isNumeric() type of function, but you could add your own:

function isNumeric(n) {
  return !isNaN(parseFloat(n)) && isFinite(n);
}

NOTE: Since parseInt() is not a proper way to check for numeric it should NOT be used.

Use double braces {{ or }} so your code becomes:

sb.AppendLine(String.Format("public {0} {1} {{ get; private set; }}", 
prop.Type, prop.Name));

// For prop.Type of "Foo" and prop.Name of "Bar", the result would be:
// public Foo Bar { get; private set; }

Or alternatively, you could use this:

WHERE CHARINDEX(N'Apples', someColumn) = 0

Not sure which one performs better - you gotta test it! :-)

UPDATE: the performance seems to be pretty much on a par with the other solution (WHERE someColumn NOT LIKE '%Apples%') - so it's really just a question of your personal preference.

function forEachNested(O, f, cur){
    O = [ O ]; // ensure that f is called with the top-level object
    while (O.length) // keep on processing the top item on the stack
        if(
           !f( cur = O.pop() ) && // do not spider down if `f` returns true
           cur instanceof Object && // ensure cur is an object, but not null 
           [Object, Array].includes(cur.constructor) //limit search to [] and {}
        ) O.push.apply(O, Object.values(cur)); //search all values deeper inside
}

To use the above function, pass the array as the first argument and the callback function as the second argument. The callback function will receive 1 argument when called: the current item being iterated.

(function(){"use strict";

var cars = {"label":"Autos","subs":[{"label":"SUVs","subs":[]},{"label":"Trucks","subs":[{"label":"2 Wheel Drive","subs":[]},{"label":"4 Wheel Drive","subs":[{"label":"Ford","subs":[]},{"label":"Chevrolet","subs":[]}]}]},{"label":"Sedan","subs":[]}]};

var lookForCar = prompt("enter the name of the car you are looking for (e.g. 'Ford')") || 'Ford';
lookForCar = lookForCar.replace(/[^ \w]/g, ""); // incaseif the user put quotes or something around their input
lookForCar = lookForCar.toLowerCase();

var foundObject = null;
forEachNested(cars, function(currentValue){
    if(currentValue.constructor === Object &&
      currentValue.label.toLowerCase() === lookForCar) {
        foundObject = currentValue;
    }
});
if (foundObject !== null) {
    console.log("Found the object: " + JSON.stringify(foundObject, null, "\t"));
} else {
    console.log('Nothing found with a label of "' + lookForCar + '" :(');
}

function forEachNested(O, f, cur){
    O = [ O ]; // ensure that f is called with the top-level object
    while (O.length) // keep on processing the top item on the stack
        if(
           !f( cur = O.pop() ) && // do not spider down if `f` returns true
           cur instanceof Object && // ensure cur is an object, but not null 
           [Object, Array].includes(cur.constructor) //limit search to [] and {}
        ) O.push.apply(O, Object.values(cur)); //search all values deeper inside
}

})();

A "cheat" alternative might be to use JSON.stringify to iterate. HOWEVER, JSON.stringify will call the toString method of each object it passes over, which may produce undesirable results if you have your own special uses for the toString.

function forEachNested(O, f, v){
    typeof O === "function" ? O(v) : JSON.stringify(O,forEachNested.bind(0,f));
    return v; // so that JSON.stringify keeps on recursing
}

(function(){"use strict";

var cars = {"label":"Autos","subs":[{"label":"SUVs","subs":[]},{"label":"Trucks","subs":[{"label":"2 Wheel Drive","subs":[]},{"label":"4 Wheel Drive","subs":[{"label":"Ford","subs":[]},{"label":"Chevrolet","subs":[]}]}]},{"label":"Sedan","subs":[]}]};

var lookForCar = prompt("enter the name of the car you are looking for (e.g. 'Ford')") || 'Ford';
lookForCar = lookForCar.replace(/[^ \w]/g, ""); // incaseif the user put quotes or something around their input
lookForCar = lookForCar.toLowerCase();

var foundObject = null;
forEachNested(cars, function(currentValue){
    if(currentValue.constructor === Object &&
      currentValue.label.toLowerCase() === lookForCar) {
        foundObject = currentValue;
    }
});
if (foundObject !== null)
    console.log("Found the object: " + JSON.stringify(foundObject, null, "\t"));
else
    console.log('Nothing found with a label of "' + lookForCar + '" :(');

function forEachNested(O, f, v){
    typeof O === "function" ? O(v) : JSON.stringify(O,forEachNested.bind(0,f));
    return v; // so that JSON.stringify keeps on recursing
}
})();

However, while the above method might be useful for demonstration purposes, Object.values is not supported by Internet Explorer and there are many terribly illperformant places in the code:

1. the code changes the value of input parameters (arguments) [lines 2 & 5],
2. the code calls Array.prototype.push and Array.prototype.pop on every single item [lines 5 & 8],
3. the code only does a pointer-comparison for the constructor which does not work on out-of-window objects [line 7],
4. the code duplicates the array returned from Object.values [line 8],
5. the code does not localize window.Object or window.Object.values [line 9],
6. and the code needlessly calls Object.values on arrays [line 8].

Below is a much much faster version that should be far faster than any other solution. The solution below fixes all of the performance problems listed above. However, it iterates in a much different way: it iterates all the arrays first, then iterates all the objects. It continues to iterate its present type until complete exhaustion including iteration subvalues inside the current list of the current flavor being iterated. Then, the function iterates all of the other type. By iterating until exhaustion before switching over, the iteration loop gets hotter than otherwise and iterates even faster. This method also comes with an added advantage: the callback which is called on each value gets passed a second parameter. This second parameter is the array returned from Object.values called on the parent hash Object, or the parent Array itself.

var foundObject = null;
forEachNested(cars, function(currentValue){
    if(currentValue.constructor === Object &&
      currentValue.label.toLowerCase() === lookForCar) {
        foundObject = currentValue;
    }
});
if (foundObject !== null) {
    console.log("Found the object: " + JSON.stringify(foundObject, null, "\t"));
} else {
    console.log('Nothing found with a label of "' + lookForCar + '" :(');
}

})();

If you have a problem with circular references (e.g. having object A's values being object A itself in such as that object A contains itself), or you just need the keys then the following slower solution is available.

function forEachNested(O, f){
    O = Object.entries(O);
    var cur;
    function applyToEach(x){return cur[1][x[0]] === x[1]} 
    while (O.length){
        cur = O.pop();
        f(cur[0], cur[1]);
        if (typeof cur[1] === 'object' && cur[1].constructor === Object && 
          !O.some(applyToEach))
            O.push.apply(O, Object.entries(cur[1]));
    }
}

Because these methods do not use any recursion of any sort, these functions are well suited for areas where you might have thousands of levels of depth. The stack limit varies greatly from browser to browser, so recursion to an unknown depth is not very wise in Javascript.

I was going mad trying to figure out why my JavaScript file would not debug and it took looking in the "Script Documents" (the loaded scripts) to realise my script was not there.

The designer had edited the page headers and replaced my individual developer JavaScript files with a combined minified version. I didn't realise until an half an hour's worth of googling and debugging attempts.

So basically I recommend looking in that list when debugging. If it's not in there, it can't be debugged. Doh.

The designer was doing the right thing. It just should have happened at the release stage, not the beta. A list of which script includes were minified would also be good, so it can be rebuilt for development.

BTW I tried the Modules stuff from previous answers, and obviously it was not that. The script was actually not being loaded in the project. Sigh.

Here are the steps to install JSToolNPP plugin on your Notepad++.

1. Download 64bit version from Sourceforge or the 32bit version if you are on a 32-bit OS.

   64bit - JSToolNPP.1.21.0.uni.64.zip: Download from SourceForget.net
   

2. Notepad++ before installation

3. Unzip the downloaded JSToolNPP.1.21.0.uni.64 and copy the JSMinNPP.dll and place it under C:\Program Files\Notepad++\plugins.

4. Close Notepad++ and reopen it. If you have downloaded an incompatible dll, then it will complain, else it will open successfully. If it complains about incompatibility, go back to STEP 1 and download the correct bit version as per your OS. Check Plugins in Notepad++.

5. Paste a sample unformatted but valid JSON data in Notepad++.

6. Select all text in Notepad++ (CTRL+A) and format using Plugins -> JSTool -> JSFormat.

NOTE: On side note, if you do not want to install any plugins like this, I would recommend using the following 2 best online formatters.

• https://jsonformatter.curiousconcept.com/
• https://jsonformatter.org/

Kotlin

There are available Extension methods to parse them into other primitive types.

• "10".toInt()
• "10".toLong()
• "true".toBoolean()
• "10.0".toFloat()
• "10.0".toDouble()
• "10".toByte()
• "10".toShort()

Java

String num = "10";
Integer.parseInt(num );

Since not all of my clients use authenticated SMTP accounts, I resorted to using the SMTP account only if app key values are supplied in web.config file.

Here is the VB code:

sSMTPUser = ConfigurationManager.AppSettings("SMTPUser")
sSMTPPassword = ConfigurationManager.AppSettings("SMTPPassword")

If sSMTPUser.Trim.Length > 0 AndAlso sSMTPPassword.Trim.Length > 0 Then
    NetClient.Credentials = New System.Net.NetworkCredential(sSMTPUser, sSMTPPassword)

    sUsingCredentialMesg = "(Using Authenticated Account) " 'used for logging purposes
End If

NetClient.Send(Message)

If you want to create a CORS service from PHP, you can use this code as the first step in your file that handles the requests:

// Allow from any origin
if(isset($_SERVER["HTTP_ORIGIN"]))
{
    // You can decide if the origin in $_SERVER['HTTP_ORIGIN'] is something you want to allow, or as we do here, just allow all
    header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
}
else
{
    //No HTTP_ORIGIN set, so we allow any. You can disallow if needed here
    header("Access-Control-Allow-Origin: *");
}

header("Access-Control-Allow-Credentials: true");
header("Access-Control-Max-Age: 600");    // cache for 10 minutes

if($_SERVER["REQUEST_METHOD"] == "OPTIONS")
{
    if (isset($_SERVER["HTTP_ACCESS_CONTROL_REQUEST_METHOD"]))
        header("Access-Control-Allow-Methods: POST, GET, OPTIONS, DELETE, PUT"); //Make sure you remove those you do not want to support

    if (isset($_SERVER["HTTP_ACCESS_CONTROL_REQUEST_HEADERS"]))
        header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");

    //Just exit with 200 OK with the above headers for OPTIONS method
    exit(0);
}
//From here, handle the request as it is ok

For me issue is resolved by changing envs like this:

 env.put("LDAP_BASEDN", base)
 env.put(Context.SECURITY_PRINCIPAL,"user@domain")
