Ok, here is the JS code:

var data = JSON.parse('{"c":{"a":{"name":"cable - black","value":2}}}')

for (var event in data) {
    var dataCopy = data[event];
    for (data in dataCopy) {
        var mainData = dataCopy[data];
        for (key in mainData) {
            if (key.match(/name|value/)) {
                alert('key : ' + key + ':: value : ' + mainData[key])
            }
        }
    }
}?

There is also the possibility of Maven using a different version of JDK, in that case you can set Maven to use the project default JDK version.

I wanto to display the count of rows in the excel sheet after the filter option has been applied.

So I declared the count of last rows as a variable that can be added to the Msgbox

Sub lastrowcall()
Dim hm As Worksheet
Dim dm As Worksheet
Set dm = ActiveWorkbook.Sheets("datecopy")
Set hm = ActiveWorkbook.Sheets("Home")
Dim lngStart As String, lngEnd As String
lngStart = hm.Range("E23").Value
lngEnd = hm.Range("E25").Value
Dim last_row As String
last_row = dm.Cells(Rows.Count, 1).End(xlUp).Row

MsgBox ("Number of test results between the selected dates " + lngStart + " 
and " + lngEnd + " are " + last_row + ". Please Select Yes to continue 
Analysis")


End Sub

This is a perfect example of where you should use the macro recorder. Turn on the recorder and set the color of the cells through the UI. Stop the recorder and review the macro. It will generate a bunch of extraneous code, but it will also show you syntax that works for what you are trying to accomplish. Strip out what you don't need and modify (if you need to) what's left.

I'm putting this in a new answer because no linebreaks / codeblocks in comments. I assume you want those nans to turn into a blank string? I couldn't find a nice way to do this, only do the ugly method:

s = pd.Series([1001.,1002.,None])
a = s.loc[s.isnull()].fillna('')
b = s.loc[s.notnull()].astype(int).astype(str)
result = pd.concat([a,b])

Not very efficient, but if you must use a list, you can deference the iterator

*myList.begin()+N

Just like @aku answer, but using extension methods:

string @namespace = "...";

var types = Assembly.GetExecutingAssembly().GetTypes()
    .Where(t => t.IsClass && t.Namespace == @namespace)
    .ToList();

types.ForEach(t => Console.WriteLine(t.Name));

You can prints lines with multiple colors without HTML as:

TextView textView = (TextView) findViewById(R.id.mytextview01);
Spannable word = new SpannableString("Your message");        

word.setSpan(new ForegroundColorSpan(Color.BLUE), 0, word.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

textView.setText(word);
Spannable wordTwo = new SpannableString("Your new message");        

wordTwo.setSpan(new ForegroundColorSpan(Color.RED), 0, wordTwo.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.append(wordTwo);

if nodeA and nodeB are siblings, likes two <tr> in the same <tbody>, you can just use $(trA).insertAfter($(trB)) or $(trA).insertBefore($(trB)) to swap them, it works for me. and you don't need to call $(trA).remove() before, else you need to re-bind some click events on $(trA)

remove the http or https from wget https:github.com/facebook/facebook-php-sdk/archive/master.zip . this worked fine for me.

You can just use pip for installing packages, even when you are using anaconda:

pip install -U scikit-learn scipy matplotlib

This should work for installing the package.

And for Python 3.x just use pip3:

pip3 install -U scikit-learn scipy matplotlib

Isn't this the normal way to free the memory associated with an object?

This is a common way of managing dynamically allocated memory, but it's not a good way to do so. This sort of code is brittle because it is not exception-safe: if an exception is thrown between when you create the object and when you delete it, you will leak that object.

It is far better to use a smart pointer container, which you can use to get scope-bound resource management (it's more commonly called resource acquisition is initialization, or RAII).

As an example of automatic resource management:

void test()
{
    std::auto_ptr<Object1> obj1(new Object1);

} // The object is automatically deleted when the scope ends.

Depending on your use case, auto_ptr might not provide the semantics you need. In that case, you can consider using shared_ptr.

As for why your program crashes when you delete the object, you have not given sufficient code for anyone to be able to answer that question with any certainty.

100% with what MarkR said. autocommit makes each statement a one statement transaction.

SHOW ENGINE INNODB STATUS should give you some clues as to the deadlock reason. Have a good look at your slow query log too to see what else is querying the table and try to remove anything that's doing a full tablescan. Row level locking works well but not when you're trying to lock all of the rows!

This is offset calculation independent from device. Gets the overlapped height between keyboard and textfield:

func keyboardShown(notification: NSNotification) {
    let info  = notification.userInfo!
    let value: AnyObject = info[UIKeyboardFrameEndUserInfoKey]!

    let rawFrame = value.CGRectValue
    let keyboardFrame = view.convertRect(rawFrame, fromView: nil)

    let screenHeight = UIScreen.mainScreen().bounds.size.height;
    let Ylimit = screenHeight - keyboardFrame.size.height
    let textboxOriginInSuperview:CGPoint = self.view.convertPoint(CGPointZero, fromCoordinateSpace: lastTextField!)

    self.keyboardHeight = (textboxOriginInSuperview.y+self.lastTextField!.frame.size.height) - Ylimit

    if(self.keyboardHeight>0){
        self.animateViewMoving(true, moveValue: keyboardHeight!)
    }else{
        keyboardHeight=0
    }
}

keyBoardHeight is the offset.

isset checks if the variable is set and, if so, whether its value is not NULL. The latter part is (in my opinion) not within the scope of this function. There is no decent workaround to determine whether a variable is NULL because it is not set or because it is explicitly set to NULL.

Here is one possible solution:

$e1 = error_get_last();
$isNULL = is_null(@$x);
$e2 = error_get_last();
$isNOTSET = $e1 != $e2;
echo sprintf("isNOTSET: %d, isNULL: %d", $isNOTSET, $isNULL);

// Sample output:
// when $x is not set: isNOTSET: 1, isNULL: 1
// when $x = NULL:     isNOTSET: 0, isNULL: 1
// when $x = false:    isNOTSET: 0, isNULL: 0

Other workaround is to probe the output of get_defined_vars():

$vars = get_defined_vars();
$isNOTSET = !array_key_exists("x", $vars);
$isNULL = $isNOTSET ? true : is_null($x);
echo sprintf("isNOTSET: %d, isNULL: %d", $isNOTSET, $isNULL);

// Sample output:
// when $x is not set: isNOTSET: 1, isNULL: 1
// when $x = NULL:     isNOTSET: 0, isNULL: 1
// when $x = false:    isNOTSET: 0, isNULL: 0

Assuming that the program cannot be redesigned to avoid the cast (ref. Keith Thomson's answer):

To cast from size_t to int you need to ensure that the size_t does not exceed the maximum value of the int. This can be done using std::numeric_limits:

int SizeTToInt(size_t data)
{
    if (data > std::numeric_limits<int>::max())
        throw std::exception("Invalid cast.");
    return std::static_cast<int>(data);
}

If you need to cast from size_t to double, and you need to ensure that you don't lose precision, I think you can use a narrow cast (ref. Stroustrup: The C++ Programming Language, Fourth Edition):

template<class Target, class Source>
Target NarrowCast(Source v)
{
    auto r = static_cast<Target>(v);
    if (static_cast<Source>(r) != v)
        throw RuntimeError("Narrow cast failed.");
    return r;
}

I tested using the narrow cast for size_t-to-double conversions by inspecting the limits of the maximum integers floating-point-representable integers (code uses googletest):

EXPECT_EQ(static_cast<size_t>(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() - 2 })), size_t{ IntegerRepresentableBoundary() - 2 });
EXPECT_EQ(static_cast<size_t>(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() - 1 })), size_t{ IntegerRepresentableBoundary() - 1 });
EXPECT_EQ(static_cast<size_t>(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() })), size_t{ IntegerRepresentableBoundary() });
EXPECT_THROW(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() + 1 }), std::exception);
EXPECT_EQ(static_cast<size_t>(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() + 2 })), size_t{ IntegerRepresentableBoundary() + 2 });
EXPECT_THROW(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() + 3 }), std::exception);
EXPECT_EQ(static_cast<size_t>(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() + 4 })), size_t{ IntegerRepresentableBoundary() + 4 });
EXPECT_THROW(NarrowCast<double>(size_t{ IntegerRepresentableBoundary() + 5 }), std::exception);

where

constexpr size_t IntegerRepresentableBoundary()
{
    static_assert(std::numeric_limits<double>::radix == 2, "Method only valid for binary floating point format.");
    return size_t{2} << (std::numeric_limits<double>::digits - 1);
}

That is, if N is the number of digits in the mantissa, for doubles smaller than or equal to 2^N, integers can be exactly represented. For doubles between 2^N and 2^(N+1), every other integer can be exactly represented. For doubles between 2^(N+1) and 2^(N+2) every fourth integer can be exactly represented, and so on.

Basically its this: You have three files: Your long running PHP script, a progress bar controlled by Javascript (@SapphireSun gives an option), and a progress script. The hard part is the Progress Script; your long script must be able to report its progress without direct communication to your progress script. This can be in the form of session id's mapped to progress meters, a database, or check of whats not finished.

The process is simple:

1. Execute your script and zero out progress bar
2. Using AJAX, query your progress script
3. Progress script must somehow check on progress
4. Change the progress bar to reflect the value
5. Clean up when finished

I'm surprised nobody mentioned the command php artisan route:list, which gives a list of all registered app routes (including Auth::routes() and Passport::routes() if registered)

The negation operator in Python is not. Therefore just replace your ! with not.

For your example, do this:

if not os.path.exists("/usr/share/sounds/blues") :
    proc = subprocess.Popen(["mkdir", "/usr/share/sounds/blues"])
    proc.wait()

For your specific example (as Neil said in the comments), you don't have to use the subprocess module, you can simply use os.mkdir() to get the result you need, with added exception handling goodness.

Example:

blues_sounds_path = "/usr/share/sounds/blues"
if not os.path.exists(blues_sounds_path):
    try:
        os.mkdir(blues_sounds_path)
    except OSError:
        # Handle the case where the directory could not be created.

Have you tried..

curl_setopt($process, CURLOPT_SSL_VERIFYPEER, false);

If you are consuming a trusted source you can skip the verify.

You can print the function by evaluating the name of it in the console, like so

> unknownFunc
function unknownFunc(unknown) {
    alert('unknown seems to be ' + unknown);
}

this won't work for built-in functions, they will only display [native code] instead of the source code.

EDIT: this implies that the function has been defined within the current scope.

If You Use Namespaces

In my own findings, I think it's good to mention that you (as far as I can tell) must declare the full namespace path of a class.

MyClass.php

namespace com\company\lib;
class MyClass {
}

index.php

namespace com\company\lib;

//Works fine
$i = new MyClass();

$cname = 'MyClass';

//Errors
//$i = new $cname;

//Works fine
$cname = "com\\company\\lib\\".$cname;
$i = new $cname;

We can change context root path using a simple entry in the properties file.

application.properties

### Spring boot 1.x #########
server.contextPath=/ClientApp

### Spring boot 2.x #########
server.servlet.context-path=/ClientApp

You can use .deepEqual()

const { assert } = require('chai');

assert.deepEqual([0,0], [0,0]);

The Permanent Generation (PermGen) space has completely been removed and is kind of replaced by a new space called Metaspace.The consequences of the PermGen removal is that obviously the PermSize and MaxPermSize JVM arguments are ignored and you will never get a java.lang.OutOfMemoryError: PermGen error. The JDK 8 HotSpot JVM is now using native memory for the representation of class metadata and is called Metaspace. Read More>>

To fix this, you need to supply an extra parameter to openssl when you're creating the cert, basically

-sha256 -extfile v3.ext

where v3.ext is a file like so, with %%DOMAIN%% replaced with the same name you use as your Common Name. More info here and over here. Note that typically you'd set the Common Name and %%DOMAIN%% to the domain you're trying to generate a cert for. So if it was www.mysupersite.com, then you'd use that for both.

v3.ext

authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
subjectAltName = @alt_names

[alt_names]
DNS.1 = %%DOMAIN%%

Note: Scripts that address this issue, and create fully trusted ssl certs for use in Chrome, Safari and from Java clients can be found here

Another note: If all you're trying to do is stop chrome from throwing errors when viewing a self signed certificate, you can can tell Chrome to ignore all SSL errors for ALL sites by starting it with a special command line option, as detailed here on SuperUser

You're looking for the onclose event.

see: https://developer.mozilla.org/en/DOM/window.onclose

note that not all browsers support this (for example firefox 2)

I am not very sure if what i did was right, but it worked anyways. I renamed repo2 folder present inside repo1, and committed the changes. In my case it was just one repo which i wanted to merge , so this approach worked. Later on, some path changes were done.

Look for jQuery site

HTML:

<form>
  <input class="target" type="text" value="Field 1">
  <select class="target">
    <option value="option1" selected="selected">Option 1</option>
    <option value="option2">Option 2</option>
  </select>
</form>
<div id="other">
  Trigger the handler
</div>

JAVASCRIPT:

$( ".target" ).change(function() {
  alert( "Handler for .change() called." );
});

jQuery's example:

To add a validity test to all text input elements:

$( "input[type='text']" ).change(function() {
  // Check input( $( this ).val() ) for validity here
});

Greg is absolutely correct. This kind of parsing cannot be done with regular expressions. I suppose it is possible to build some horrendous monstrosity that would work for many cases, but then you'll just run across something that does.

You really need to use more traditional parsing techniques. For example, its pretty simple to write a recursive decent parser to do what you need.

Dim SourcePath As String = "c:\SomeFolder\SomeFileYouWantToCopy.txt" 'This is just an example string and could be anything, it maps to fileToCopy in your code.
Dim SaveDirectory As string = "c:\DestinationFolder"

Dim Filename As String = System.IO.Path.GetFileName(SourcePath) 'get the filename of the original file without the directory on it
Dim SavePath As String = System.IO.Path.Combine(SaveDirectory, Filename) 'combines the saveDirectory and the filename to get a fully qualified path.

If System.IO.File.Exists(SavePath) Then
   'The file exists
Else
    'the file doesn't exist
End If

after
systemctl restart php-fpm
the Gd library works.

As explained in the documentation, by using an @RequestParam annotation:

public @ResponseBody String byParameter(@RequestParam("foo") String foo) {
    return "Mapped by path + method + presence of query parameter! (MappingController) - foo = "
           + foo;
}

You can use this code:

int count;
            try {
                URL url = new URL(f_url[0]);
                URLConnection conection = url.openConnection();
                conection.setConnectTimeout(TIME_OUT);
                conection.connect();
                // Getting file length
                int lenghtOfFile = conection.getContentLength();
                // Create a Input stream to read file - with 8k buffer
                InputStream input = new BufferedInputStream(url.openStream(),
                        8192);
                // Output stream to write file
                OutputStream output = new FileOutputStream(
                        "/sdcard/9androidnet.jpg");

                byte data[] = new byte[1024];
                long total = 0;
                while ((count = input.read(data)) != -1) {
                    total += count;
                    // publishing the progress....
                    // After this onProgressUpdate will be called
                    publishProgress("" + (int) ((total * 100) / lenghtOfFile));
                    // writing data to file
                    output.write(data, 0, count);
                }
                // flushing output
                output.flush();
                // closing streams
                output.close();
                input.close();
            } catch (SocketTimeoutException e) {
                connectionTimeout=true;
            } catch (Exception e) {
                Log.e("Error: ", e.getMessage());
            }

Check this: http://jsfiddle.net/h7kRt/1/,

you should change in jsfiddle on top-left to No-wrap in <head>

Your code looks good and it will work inside a normal page. In jsfiddle your function was being defined inside a load handler and thus is in a different scope. By changing to No-wrap you have it in the global scope and can use it as you wanted.

You have to append your project's path to PYTHONPATH and make sure to use absolute imports.

For UNIX (Linux, OSX, ...)

export PYTHONPATH="${PYTHONPATH}:/path/to/your/project/"

For Windows

set PYTHONPATH=%PYTHONPATH%;C:\path\to\your\project\

Absolute imports

Assuming that we have the following project structure,

+-- myproject
    +-- mypackage
    ¦   +-- a.py
    +-- anotherpackage
        +-- b.py
        +-- c.py
        +-- mysubpackage
            +-- d.py

just make sure to reference each import starting from the project's root directory. For instance,

# in module a.py
import anotherpackage.mysubpackage.d

# in module b
import anotherpackage.c
import mypackage.a

For a more comprehensive explanation, refer to the article How to fix ModuleNotFoundError and ImportError

• Use a Thread or AsyncTask for long-running operations (50ms+). Test your app to see where that is. Most operations (probably) don't require a thread, because most operations (probably) only involve a few rows. Use a thread for bulk operations.
• Share one SQLiteDatabase instance for each DB on disk between threads and implement a counting system to keep track of open connections.

Are there any best practices for these scenarios?

Share a static field between all your classes. I used to keep a singleton around for that and other things that need to be shared. A counting scheme (generally using AtomicInteger) also should be used to make sure you never close the database early or leave it open.

My solution:

The old version I wrote is available at https://github.com/Taeluf/dev/tree/main/archived/databasemanager and is not maintained. If you want to understand my solution, look at the code and read my notes. My notes are usually pretty helpful.

1. copy/paste the code into a new file named DatabaseManager. (or download it from github)
2. extend DatabaseManager and implement onCreate and onUpgrade like you normally would. You can create multiple subclasses of the one DatabaseManager class in order to have different databases on disk.
3. Instantiate your subclass and call getDb() to use the SQLiteDatabase class.
4. Call close() for each subclass you instantiated

The code to copy/paste:

import android.content.Context;
import android.database.sqlite.SQLiteDatabase;

import java.util.concurrent.ConcurrentHashMap;

A bit more modern way to do it:

const selectedValues = $('input[name="locationthemes"]:checked').map( function () { 
        return $(this).val(); 
    })
    .get()
    .join(', ');

We first find all the selected checkboxes with the given name, and then jQuery's map() iterates through each of them, calling the callback on it to get the value, and returning the result as a new jQuery collection that now holds the checkbox values. We then call get() on it to get an array of values, and then join() to concatenate them into a single string - which is then assigned to the constant selectedValues.

The grep family of commands (incl egrep, fgrep) is the usual solution for this.

$ grep pattern filename

If you're searching source code, then ack may be a better bet. It'll search subdirectories automatically and avoid files you'd normally not search (objects, SCM directories etc.)

in response to Dan's comment above:

I am using this method to implement the same thing, but for some reason I am getting an exception on the ReadObject method: "Expecting element 'root' from namespace ''.. Encountered 'None' with name '', namespace ''." Any ideas why? – Dan Appleyard Apr 6 '10 at 17:57

I had the same problem (MVC 3 build 3.0.11209.0), and the post below solved it for me. Basically the json serializer is trying to read a stream which is not at the beginning, so repositioning the stream to 0 'fixed' it...

A convenient, simple and fast way to get rid of \0 is to copy the string without the last char (\0) with the help of strncpy instead of strcpy:

strncpy(newStrg,oldStrg,(strlen(oldStrg)-1));

Maybe

SELECT count(*) FROM (
    SELECT COUNT(*) FROM Movies GROUP BY ID HAVING count(Genre) = 4
) AS the_count_total

although that would not be the sum of all the movies, just how many have 4 genre's.

So maybe you want

SELECT sum(
    SELECT COUNT(*) FROM Movies GROUP BY ID having Count(Genre) = 4
) as the_sum_total

Give permission in .htaccess as follows:

While it may immediately seem useful to utilize class instance variables, since class instance variable are shared among subclasses and they can be referred to within both singleton and instance methods, there is a singificant drawback. They are shared and so subclasses can change the value of the class instance variable, and the base class will also be affected by the change, which is usually undesirable behavior:

class C
  @@c = 'c'
  def self.c_val
    @@c
  end
end

C.c_val
 => "c" 

class D < C
end

D.instance_eval do 
  def change_c_val
    @@c = 'd'
  end
end
 => :change_c_val 

D.change_c_val
(irb):12: warning: class variable access from toplevel
 => "d" 

C.c_val
 => "d" 

Rails introduces a handy method called class_attribute. As the name implies, it declares a class-level attribute whose value is inheritable by subclasses. The class_attribute value can be accessed in both singleton and instance methods, as is the case with the class instance variable. However, the huge benefit with class_attribute in Rails is subclasses can change their own value and it will not impact parent class.

class C
  class_attribute :c
  self.c = 'c'
end

 C.c
 => "c" 

class D < C
end

D.c = 'd'
 => "d" 

 C.c
 => "c" 

Go to the .project file of your project make sure it display the same name as displayed in project folder. if not change the name. it will work.

Short answer:

x.addEventListener("click", function(e){myfunction(e, param1, param2)});

You really want to do this

flog.write("\nCompany Name: "+ pCompanyName.encode('utf-8'))

This is the "encode late" strategy described in this unicode presentation (slides 32 through 35).

Big task, chances are you shouldn't reinvent the wheel rather using an existing wheel (such as paypal).

However, if you insist on continuing. Start small, you can use a credit card processing facility (Moneris, Authorize.NET) to process credit cards. Most providers have an API you can use. Be wary that you may need to use different providers depending on the card type (Discover, Visa, Amex, Mastercard) and Country (USA, Canada, UK). So build it so that you can communicate with multiple credit card processing APIs.

Security is essential if you are storing credit cards and payment details. Ensure that you are encrypting things properly.

Again, don't reinvent the wheel. You are better off using an existing provider and focussing your development attention on solving an problem that can't easily be purchase.

I have experienced this exact problem and found, on the users machine, one of the libraries I depended on was marked as "MISSING" in the references dialog. In that case it was some office font library that was available in my version of Office 2007, but not on the client desktop.

The error you get is a complete red herring (as pointed out by divo).

Fortunately I wasn't using anything from the library, so I was able to remove it from the XLA references entirely. I guess, an extension of divo' suggested best practice would be for testing to check the XLA on all the target Office versions (not a bad idea in any case).

Deep copy literally performs a deep copy. It means, that if your class has some fields that are references, their values will be copied, not references themselves. If, for example you have two instances of a class, A & B with fields of reference type, and perform a deep copy, changing a value of that field in A won't affect a value in B. And vise-versa. Things are different with shallow copy, because only references are copied, therefore, changing this field in a copied object would affect the original object.

What type of a copy does a copy constructor does?

It is implementation - dependent. This means that there are no strict rules about that, you can implement it like a deep copy or shallow copy, however as far as i know it is a common practice to implement a deep copy in a copy constructor. A default copy constructor performs a shallow copy though.

PowerShell has built-in XML and XPath functions. You can use the Select-Xml cmdlet with an XPath query to select nodes from XML object and then .Node.'#text' to access node value.

[xml]$xml = Get-Content $serviceStatePath
$nodes = Select-Xml "//Object[Property/@Name='ServiceState' and Property='Running']/Property[@Name='DisplayName']" $xml
$nodes | ForEach-Object {$_.Node.'#text'}

Or shorter

[xml]$xml = Get-Content $serviceStatePath
Select-Xml "//Object[Property/@Name='ServiceState' and Property='Running']/Property[@Name='DisplayName']" $xml |
  % {$_.Node.'#text'}

to find the program you want you can run this command at terminal:

find / usr-name "your_program"

This may not be the exact answer for the OP, but is the answer to the Title of the question: How to Update Gradle in Android Studio (AS):

• Get latest version supported by AS: http://www.gradle.org/downloads (Currently 1.9, 1.10 is NOT supported by AS yet)
• Install: Unzip to anywhere like near where AS is installed: C:\Users[username]\gradle-1.9\
• Open AS: File->Settings->Build, Execution, Deployment->Build Tools-> Gradle->Service directory path: (Change to folder you set above) ->Click ok. Status on bottom should indicate it's busy & error should be fixed. Might have to restart AS

If you'd like to avoid hard-coding a specific design with css, but rather rely on the browser's default button, you can use the following css.

a.button {
  -webkit-appearance: button;
  -moz-appearance: button;
  appearance: button;
}

Notice that it probably won't work on IE.

This works for me:

#include <iostream>
#include <string>
#include <algorithm>

using namespace std;

int main() {
    string name[] = {"john", "bobby", "dear", "test1", "catherine", "nomi", "shinta", "martin", "abe", "may", "zeno", "zack", "angeal", "gabby"};

    int sname = sizeof(name)/sizeof(name[0]);

    sort(name, name + sname);

    for(int i = 0; i < sname; ++i)
        cout << name[i] << endl;

    return 0;
}

You can build DFA using simple modular arithmetics. We can interpret w which is a string of k-ary numbers using a following rule

V[0] = 0
V[i] = (S[i-1] * k) + to_number(str[i])

V[|w|] is a number that w is representing. If modify this rule to find w mod N, the rule becomes this.

V[0] = 0
V[i] = ((S[i-1] * k) + to_number(str[i])) mod N

and each V[i] is one of a number from 0 to N-1, which corresponds to each state in DFA. We can use this as the state transition.

See an example.

k = 2, N = 5

| V | (V*2 + 0) mod 5     | (V*2 + 1) mod 5     |
+---+---------------------+---------------------+
| 0 | (0*2 + 0) mod 5 = 0 | (0*2 + 1) mod 5 = 1 |
| 1 | (1*2 + 0) mod 5 = 2 | (1*2 + 1) mod 5 = 3 |
| 2 | (2*2 + 0) mod 5 = 4 | (2*2 + 1) mod 5 = 0 |
| 3 | (3*2 + 0) mod 5 = 1 | (3*2 + 1) mod 5 = 2 |
| 4 | (4*2 + 0) mod 5 = 3 | (4*2 + 1) mod 5 = 4 |

k = 3, N = 5

| V | 0 | 1 | 2 |
+---+---+---+---+
| 0 | 0 | 1 | 2 |
| 1 | 3 | 4 | 0 |
| 2 | 1 | 2 | 3 |
| 3 | 4 | 0 | 1 |
| 4 | 2 | 3 | 4 |

Now you can see a very simple pattern. You can actually build a DFA transition just write repeating numbers from left to right, from top to bottom, from 0 to N-1.

ComponentWillReceiveProps() is going to be deprecated in the future due to bugs and inconsistencies. An alternative solution for re-rendering a component on props change is to use ComponentDidUpdate() and ShouldComponentUpdate().

ComponentDidUpdate() is called whenever the component updates AND if ShouldComponentUpdate() returns true (If ShouldComponentUpdate() is not defined it returns true by default).

shouldComponentUpdate(nextProps){
    return nextProps.changedProp !== this.state.changedProp;
}

componentDidUpdate(props){
    // Desired operations: ex setting state
}

This same behavior can be accomplished using only the ComponentDidUpdate() method by including the conditional statement inside of it.

componentDidUpdate(prevProps){
    if(prevProps.changedProp !== this.props.changedProp){
        this.setState({          
            changedProp: this.props.changedProp
        });
    }
}

If one attempts to set the state without a conditional or without defining ShouldComponentUpdate() the component will infinitely re-render

Other answers are great! Few other things which Type can do but Interface can't

You can use union in type

type Name = string | { FullName: string };

const myName = "Jon"; // works fine

const myFullName: Name = {
  FullName: "Jon Doe", //also works fine
};

Iterating over union properties in type

type Keys = "firstName" | "lastName";

type Name = {
  [key in Keys]: string;
};

const myName: Name = {
  firstName: "jon",
  lastName: "doe",
};

Intersection in type ( however, also supported in Interface with extends)

type Name = {
  firstName: string;
  lastName: string;
};

type Address = {
  city: string;
};

const person: Name & Address = {
  firstName: "jon",
  lastName: "doe",
  city: "scranton",
};

Also not that type was introduced later as compared to interface and according to the latest release of TS type can do *almost everything which interface can and much more!

*except Declaration merging (personal opinion: It's good that it's not supported in type as it may lead to inconsistency in code)

Create a div that is the line with the code like this:

CSS

div#lineHorizontal {
    background-color: #000;
    width: //the width of the line or how far it goes sidewards;
    height: 2px;
    display: inline-block;
    margin: 0px;
 }
div#block {
    background-color: #777;
    display: inline-block;
    margin: 0px;
}

HTML

<div id="block">
</div>
<div id="lineHorizontal">
</div>
<div id="block">
</div>

This will display a block with a horizontal line to another block.

I guess you want to convert the values contained in the Map to a list? Easiest is to call the values() method of the Map interface. This will return the Collection of value objects contained in the Map.

Note that this Collection is backed by the Map object and any changes to the Map object will reflect here. So if you want a separate copy not bound to your Map object, simply create a new List object like an ArrayList passing the value Collection as below.

ArrayList<String> list = new ArrayList<String>(map.values());

A UHF RFID reader option for both Android and iOS is available from a company called U Grok It.

It is just UHF, which is "non-NFC enabled Android", if that's what you meant. My apologies if you meant an NFC reader for Android devices that don't have an NFC reader built-in.

Their reader has a range up to 7 meters (~21 feet). It connects via the audio port, not bluetooth, which has the advantage of pairing instantly, securely, and with way less of a power draw.

They have a free native SDK for Android, iOS, Cordova, and Xamarin, as well as an Android keyboard wedge.

2, 4, 5, 6, 7, 8, 9, 10, 11 (TypeScript) with Angular CLI

OneTime Setup

• npm install -g @angular/cli
• ng new projectFolder creates a new application

Bundling Step

• ng build --prod (run in command line when directory is projectFolder)

  flag prod bundle for production (see the Angular documentation for the list of option included with the production flag).

• Compress using Brotli compression the resources using the following command

  for i in dist/*; do brotli $i; done

bundles are generated by default to projectFolder/dist(/$projectFolder for v6+)**

Output

Sizes with Angular 11.0.5 with CLI 11.0.5and option CSS without Angular routing

• dist/main-[es-version].[hash].js Your application bundled [ ES5 size: 136 KB for new Angular CLI application empty, 38 KB compressed].
• dist/polyfill-[es-version].[hash].bundle.js the polyfill dependencies (@angular, RxJS...) bundled [ ES5 size: 36 KB for new Angular CLI application empty, 11 KB compressed].
• dist/index.html entry point of your application.
• dist/runtime-[es-version].[hash].bundle.js webpack loader
• dist/style.[hash].bundle.css the style definitions
• dist/assets resources copied from the Angular CLI assets configuration

Deployment

You can get a preview of your application using the ng serve --prod command that starts a local HTTP server such that the application with production files is accessible using http://localhost:4200.

For a production usage, you have to deploy all the files from the dist folder in the HTTP server of your choice.

I suspect that you have two tables with the same name. One is owned by the schema 'dbo' (dbo.PerfDiag), and the other is owned by the default schema of the account used to connect to SQL Server (something like userid.PerfDiag).

When you have an unqualified reference to a schema object (such as a table) — one not qualified by schema name — the object reference must be resolved. Name resolution occurs by searching in the following sequence for an object of the appropriate type (table) with the specified name. The name resolves to the first match:

• Under the default schema of the user.
• Under the schema 'dbo'.

The unqualified reference is bound to the first match in the above sequence.

As a general recommended practice, one should always qualify references to schema objects, for performance reasons:

• An unqualified reference may invalidate a cached execution plan for the stored procedure or query, since the schema to which the reference was bound may change depending on the credentials executing the stored procedure or query. This results in recompilation of the query/stored procedure, a performance hit. Recompilations cause compile locks to be taken out, blocking others from accessing the needed resource(s).

• Name resolution slows down query execution as two probes must be made to resolve to the likely version of the object (that owned by 'dbo'). This is the usual case. The only time a single probe will resolve the name is if the current user owns an object of the specified name and type.

[Edited to further note]

The other possibilities are (in no particular order):

• You aren't connected to the database you think you are.
• You aren't connected to the SQL Server instance you think you are.

Double check your connect strings and ensure that they explicitly specify the SQL Server instance name and the database name.

use:

sudo /etc/init.d/redis start

as of right now we do not have systemd in WSL

Well, I now have some modification to my previous answer. I have noticed that none of the answers mentioned IF NOT EXISTS. So I am going to provide a new solution of it as I have faced some problems altering the table.

IF NOT EXISTS (SELECT * FROM INFORMATION_SCHEMA.columns WHERE table_name = 'TaskSheet' AND column_name = 'IsBilledToClient')
BEGIN
ALTER TABLE dbo.TaskSheet ADD
 IsBilledToClient bit NOT NULL DEFAULT ((1))
END
GO

Here TaskSheet is the particular table name and IsBilledToClient is the new column which you are going to insert and 1 the default value. That means in the new column what will be the value of the existing rows, therefore one will be set automatically there. However, you can change as you wish with the respect of the column type like I have used BIT, so I put in default value 1.

I suggest the above system, because I have faced a problem. So what is the problem? The problem is, if the IsBilledToClient column does exists in the table table then if you execute only the portion of the code given below you will see an error in the SQL server Query builder. But if it does not exist then for the first time there will be no error when executing.

ALTER TABLE {TABLENAME}
ADD {COLUMNNAME} {TYPE} {NULL|NOT NULL}
CONSTRAINT {CONSTRAINT_NAME} DEFAULT {DEFAULT_VALUE}
[WITH VALUES]

In combination with what Guffa described, you could use the technique described in Explanation of <script type = "text/template"> ... </script> to store the HTML document in a special script element (see the link for an explanation on how this works). That's a lot easier than storing the HTML document in a string.

An other possible solution:

for(Object it : set.toArray()) { /* Create a copy */
    Integer element = (Integer)it;
    if(element % 2 == 0)
        set.remove(element);
}

Or:

Integer[] copy = new Integer[set.size()];
set.toArray(copy);

for(Integer element : copy) {
    if(element % 2 == 0)
        set.remove(element);
}

First Install React dev tools if not installed and then use the run below code in the browser console :

__REACT_DEVTOOLS_GLOBAL_HOOK__.renderers.get(1).version

You can use Thread.getCurrentThread.getId(), but why would you want to do that when LogRecord objects managed by the logger already have the thread Id. I think you are missing a configuration somewhere that logs the thread Ids for your log messages.

with the help of @JsonView we can decide fields of model classes to serialize which satisfy the minimal criteria ( we have to define the criteria) like we can have one core class with 10 properties but only 5 properties can be serialize which are needful for client only

Define our Views by simply creating following class:

public class Views
{
    static class Android{};
    static class IOS{};
    static class Web{};
}

Annotated model class with views:

public class Demo 
{
    public Demo() 
    {
    }

@JsonView(Views.IOS.class)
private String iosField;

@JsonView(Views.Android.class)
private String androidField;

@JsonView(Views.Web.class)
private String webField;

 // getters/setters
...
..
}

Now we have to write custom json converter by simply extending HttpMessageConverter class from spring as:

    public class CustomJacksonConverter implements HttpMessageConverter<Object> 
    {
    public CustomJacksonConverter() 
        {
            super();
        //this.delegate.getObjectMapper().setConfig(this.delegate.getObjectMapper().getSerializationConfig().withView(Views.ClientView.class));
        this.delegate.getObjectMapper().configure(MapperFeature.DEFAULT_VIEW_INCLUSION, true);
        this.delegate.getObjectMapper().setSerializationInclusion(Include.NON_NULL);

    }

    // a real message converter that will respond to methods and do the actual work
    private MappingJackson2HttpMessageConverter delegate = new MappingJackson2HttpMessageConverter();

    @Override
    public boolean canRead(Class<?> clazz, MediaType mediaType) {
        return delegate.canRead(clazz, mediaType);
    }

    @Override
    public boolean canWrite(Class<?> clazz, MediaType mediaType) {
        return delegate.canWrite(clazz, mediaType);
    }

    @Override
    public List<MediaType> getSupportedMediaTypes() {
        return delegate.getSupportedMediaTypes();
    }

    @Override
    public Object read(Class<? extends Object> clazz,
            HttpInputMessage inputMessage) throws IOException,
            HttpMessageNotReadableException {
        return delegate.read(clazz, inputMessage);
    }

    @Override
    public void write(Object obj, MediaType contentType, HttpOutputMessage outputMessage) throws IOException, HttpMessageNotWritableException 
    {
        synchronized(this) 
        {
            String userAgent = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest().getHeader("userAgent");
            if ( userAgent != null ) 
            {
                switch (userAgent) 
                {
                case "IOS" :
                    this.delegate.getObjectMapper().setConfig(this.delegate.getObjectMapper().getSerializationConfig().withView(Views.IOS.class));
                    break;
                case "Android" :
                    this.delegate.getObjectMapper().setConfig(this.delegate.getObjectMapper().getSerializationConfig().withView(Views.Android.class));
                    break;
                case "Web" :
                    this.delegate.getObjectMapper().setConfig(this.delegate.getObjectMapper().getSerializationConfig().withView( Views.Web.class));
                    break;
                default:
                    this.delegate.getObjectMapper().setConfig(this.delegate.getObjectMapper().getSerializationConfig().withView( null ));
                    break;
                }
            }
            else
            {
                // reset to default view
                this.delegate.getObjectMapper().setConfig(this.delegate.getObjectMapper().getSerializationConfig().withView( null ));
            }
            delegate.write(obj, contentType, outputMessage);
        }
    }

}

Now there is need to tell spring to use this custom json convert by simply putting this in dispatcher-servlet.xml

<mvc:annotation-driven>
        <mvc:message-converters register-defaults="true">
            <bean id="jsonConverter" class="com.mactores.org.CustomJacksonConverter" >
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>

That's how you will able to decide which fields to get serialize.

nmap is a useful tool for this kind of thing

Another approach, if the struct allows it, is to use a #define with the default values inside:

#define MYSTRUCT_INIT { 0, 0, true }

typedef struct
{
    int id;
    int flag;
    bool foo;
} MyStruct;

Use:

MyStruct val = MYSTRUCT_INIT;

If using maven, just add to your pom.xml:

<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>mail</artifactId>
    <version>1.5.0-b01</version>
</dependency>

Of course, you need to check the current version.

That should help

df.groupby(['NFF', 'ABUSE']).size().unstack().plot(kind='bar', stacked=True)

You can just add a new submodule and remove the old submodule using standard commands. (should prevent any accidental errors inside of .git)

Example setup:

mkdir foo; cd foo; git init; 
echo "readme" > README.md; git add README.md; git commit -m "First"
## add submodule
git submodule add git://github.com/jquery/jquery.git
git commit -m "Added jquery"
## </setup example>

Examle move 'jquery' to 'vendor/jquery/jquery' :

oldPath="jquery"
newPath="vendor/jquery/jquery"
orginUrl=`git config --local --get submodule.${oldPath}.url`

## add new submodule
mkdir -p `dirname "${newPath}"`
git submodule add -- "${orginUrl}" "${newPath}"

## remove old submodule
git config -f .git/config --remove-section "submodule.${oldPath}"
git config -f .gitmodules --remove-section "submodule.${oldPath}"
git rm --cached "${oldPath}"
rm -rf "${oldPath}"              ## remove old src
rm -rf ".git/modules/${oldPath}" ## cleanup gitdir (housekeeping)

## commit
git add .gitmodules
git commit -m "Renamed ${oldPath} to ${newPath}"

Bonus method for large submodules:

If the submodule is large and you prefer not to wait for the clone, you can create the new submodule using the old as origin, and then switch the origin.

Example (use same example setup)

oldPath="jquery"
newPath="vendor/jquery/jquery"
baseDir=`pwd`
orginUrl=`git config --local --get submodule.${oldPath}.url`

# add new submodule using old submodule as origin
mkdir -p `dirname "${newPath}"`
git submodule add -- "file://${baseDir}/${oldPath}" "${newPath}"

## change origin back to original
git config -f .gitmodules submodule."${newPath}".url "${orginUrl}"
git submodule sync -- "${newPath}"

## remove old submodule
...

This is a platform-specific typedef. For example, on a particular machine, it might be unsigned int or unsigned long. You should use this definition for more portability of your code.

My solution is similar to those above but I have abstracted the gesture handling into an abstract class OnGestureRegisterListener.java, which includes swipe, click and long click gestures.

OnGestureRegisterListener.java

public abstract class OnGestureRegisterListener implements View.OnTouchListener {

    private final GestureDetector gestureDetector;
    private View view;

    public OnGestureRegisterListener(Context context) {
        gestureDetector = new GestureDetector(context, new GestureListener());
    }

    @Override
    public boolean onTouch(View view, MotionEvent event) {
        this.view = view;
        return gestureDetector.onTouchEvent(event);
    }

    public abstract void onSwipeRight(View view);
    public abstract void onSwipeLeft(View view);
    public abstract void onSwipeBottom(View view);
    public abstract void onSwipeTop(View view);
    public abstract void onClick(View view);
    public abstract boolean onLongClick(View view);

    private final class GestureListener extends GestureDetector.SimpleOnGestureListener {

        private static final int SWIPE_THRESHOLD = 100;
        private static final int SWIPE_VELOCITY_THRESHOLD = 100;

        @Override
        public boolean onDown(MotionEvent e) {
            return true;
        }

        @Override
        public void onLongPress(MotionEvent e) {
            onLongClick(view);
            super.onLongPress(e);
        }

        @Override
        public boolean onSingleTapUp(MotionEvent e) {
            onClick(view);
            return super.onSingleTapUp(e);
        }

        @Override
        public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
            boolean result = false;
            try {
                float diffY = e2.getY() - e1.getY();
                float diffX = e2.getX() - e1.getX();
                if (Math.abs(diffX) > Math.abs(diffY)) {
                    if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
                        if (diffX > 0) {
                            onSwipeRight(view);
                        } else {
                            onSwipeLeft(view);
                        }
                        result = true;
                    }
                }
                else if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffY > 0) {
                        onSwipeBottom(view);
                    } else {
                        onSwipeTop(view);
                    }
                    result = true;
                }
            } catch (Exception exception) {
                exception.printStackTrace();
            }
            return result;
        }

    }
}

And use it like so. Note that you can also easily pass in your View parameter.

OnGestureRegisterListener onGestureRegisterListener = new OnGestureRegisterListener(this) {
    public void onSwipeRight(View view) {
        // Do something
    }
    public void onSwipeLeft(View view) {
        // Do something
    }
    public void onSwipeBottom(View view) {
        // Do something
    }
    public void onSwipeTop(View view) {
        // Do something
    }
    public void onClick(View view) {
        // Do something
    }
    public boolean onLongClick(View view) { 
        // Do something
        return true;
    }
};

Button button = findViewById(R.id.my_button);
button.setOnTouchListener(onGestureRegisterListener);

Rails provides a solution to this: shallow nesting.

I think this is a good because when you deal directly with a known resource, there's no need to use nested routes, as has been discussed in other answers here.

Try man exit.

Oh, and:

#include <stdlib.h>

int main(void) {
  /*  ...  */
  if (error_occured) {
    return (EXIT_FAILURE);
  }
  /*  ...  */
  return (EXIT_SUCCESS);
}

Use: LOGGER.log(Level.INFO, "Got an exception.", e);
or LOGGER.info("Got an exception. " + e.getMessage());

The scenarios that you have mentioned are not of overloading, you are just concatenating different variables with a String.

System.out.print("Hello World");

System.out.print("My name is" + foo);

System.out.print("Sum of " + a + "and " + b + "is " + c); 

System.out.print("Total USD is " + usd);

in all of these cases, you are only calling print(String s) because when something is concatenated with a string it gets converted to a String by calling the toString() of that object, and primitives are directly concatenated. However if you want to know of different signatures then yes print() is overloaded for various arguments.

Edit: As Charles Bailey rightly points out in a comment below, this won't work if there are characters buffered in stdin, and there's really no good way to work around that. If you're running with a debugger attached, John Dibling's suggested solution is probably the cleanest solution to your problem.

That said, I'll leave this here and maybe someone else will find it useful. I've used it a lot as a quick hack of sorts when writing tests during development.

At the end of your main function, you can call std::getchar();

This will get a single character from stdin, thus giving you the "press any key to continue" sort of behavior (if you actually want a "press any key" message, you'll have to print one yourself).

You need to #include <cstdio> for getchar.

Have you tried using PHP's serialize()? That allows you to store the contents of a variable's array in a string PHP understands and is safe for the database (assuming you've escaped it first).

$array = array(
    1 => 'some data',
    2 => 'some more'
);

//Assuming you're already connected to the database
$sql = sprintf("INSERT INTO `yourTable` (`rowID`, `rowContent`) VALUES (NULL, '%s')"
     ,  serialize(mysql_real_escape_string($array, $dbConnection)));
mysql_query($sql, $dbConnection) or die(mysql_error());

You can also do the exact same without a numbered array

$array2 = array(
    'something' => 'something else'
);

or

$array3 = array(
    'somethingNew'
);

Yes it is simple to do.

Sub CompactRepair()
  Dim control As Office.CommandBarControl
  Set control = CommandBars.FindControl( Id:=2071 )
  control.accDoDefaultAction
End Sub

Basically it just finds the "Compact and repair" menuitem and clicks it, programatically.

Funnily i was getting the following error for having one th-/th pair too many and still google directed me here. I'll leave it written down so people can find it.

If you need a quick fix, simply add this before the line of your import:

I use PHP as my serverside language, so the example i will write in it - but i'm sure there is a method in your server side as well.

Just have your serverside language add it from a variable. w/ php something like that would go as follows.

Do note, that this will only work if the script is loaded with the page load. If you want to load it dynamically, this solution will not help you.

PHP

HTML

<head>
    <script type="text/javascript"> <?php echo $decodedstring ?> </script>
</head>

In Summary: Decode with serverside and put it in your HTML using the server language.

FYI if you can want to replace simultaneous muti-linebreaks with single line break then you can use

myString.trim().replaceAll("[\n]{2,}", "\n")

Or replace with a single space

myString.trim().replaceAll("[\n]{2,}", " ")

I found this brilliant post on redirection: All about redirections

Redirect both standard output and standard error to a file

$ command &>file

This one-liner uses the &> operator to redirect both output streams - stdout and stderr - from command to file. This is Bash's shortcut for quickly redirecting both streams to the same destination.

Here is how the file descriptor table looks like after Bash has redirected both streams:

As you can see, both stdout and stderr now point to file. So anything written to stdout and stderr gets written to file.

There are several ways to redirect both streams to the same destination. You can redirect each stream one after another:

$ command >file 2>&1

This is a much more common way to redirect both streams to a file. First stdout is redirected to file, and then stderr is duplicated to be the same as stdout. So both streams end up pointing to file.

When Bash sees several redirections it processes them from left to right. Let's go through the steps and see how that happens. Before running any commands, Bash's file descriptor table looks like this:

Now Bash processes the first redirection >file. We've seen this before and it makes stdout point to file:

Next Bash sees the second redirection 2>&1. We haven't seen this redirection before. This one duplicates file descriptor 2 to be a copy of file descriptor 1 and we get:

Both streams have been redirected to file.

However be careful here! Writing

command >file 2>&1

is not the same as writing:

$ command 2>&1 >file

The order of redirects matters in Bash! This command redirects only the standard output to the file. The stderr will still print to the terminal. To understand why that happens, let's go through the steps again. So before running the command, the file descriptor table looks like this:

Now Bash processes redirections left to right. It first sees 2>&1 so it duplicates stderr to stdout. The file descriptor table becomes:

Now Bash sees the second redirect, >file, and it redirects stdout to file:

Do you see what happens here? Stdout now points to file, but the stderr still points to the terminal! Everything that gets written to stderr still gets printed out to the screen! So be very, very careful with the order of redirects!

Also note that in Bash, writing

$ command &>file

is exactly the same as:

$ command >&file

It's a old code, anyway, try it:

import java.util.Arrays;
import java.util.List;
import java.util.ArrayList;
public class StringArrayTest
{
   public static void main(String[] args)
   {
      String[] words = {"word1", "word2", "word3", "word4", "word5"};

      List<String> wordList = Arrays.asList(words);

      for (String e : wordList)
      {
         System.out.println(e);
      }

Download and install LINQPad, it works for SQL Server, MySQL, SQLite and also SDF (SQL CE 4.0).

Steps for open SDF Files:

1. Click Add Connection

2. Select Build data context automatically and Default (LINQ to SQL), then Next.

3. Under Provider choose SQL CE 4.0.

4. Under Database with Attach database file selected, choose Browse to select your .sdf file.

5. Click OK.

If you're only supporting IE 9 or higher, you can use this CSS that will smoothly scale to the size of the window. You may need to tweak the "200px" though, depending on the height of your header or footer.

.modal-body{
    max-height: calc(100vh - 200px);
    overflow-y: auto;
}

For rendering my models in JSON in django 1.9 I had to do the following in my views.py:

from django.core import serializers
from django.http import HttpResponse
from .models import Mymodel

def index(request):
    objs = Mymodel.objects.all()
    jsondata = serializers.serialize('json', objs)
    return HttpResponse(jsondata, content_type='application/json')

Like this:

for pet in pets :
  print(pet)

In fact, Python only has foreach style for loops.

The best that I've been able to do is

$(this).closest('.modal').modal('toggle');

This gets the modal holding the DOM object you triggered the event on (guessing you're clicking a button). Gets the closest parent '.modal' and toggles it. Obviously only works because it's inside the modal you clicked.

You can however do this:

$(".modal:visible").modal('toggle');

This gets the modal that is displaying (since you can only have one open at a time), and triggers the 'toggle' This would not work without ":visible"

You are calling:

JSON.parse(scatterSeries)

But when you defined scatterSeries, you said:

var scatterSeries = []; 

When you try to parse it as JSON it is converted to a string (""), which is empty, so you reach the end of the string before having any of the possible content of a JSON text.

scatterSeries is not JSON. Do not try to parse it as JSON.

data is not JSON either (getJSON will parse it as JSON automatically).

ch is JSON … but shouldn't be. You should just create a plain object in the first place:

var ch = {
    "name": "graphe1",
    "items": data.results[1]
};

scatterSeries.push(ch);

In short, for what you are doing, you shouldn't have JSON.parse anywhere in your code. The only place it should be is in the jQuery library itself.

        var colors = new Dictionary < string, string > ();
        colors["10"] = "Red";

Binding to Combobox

        comboBox1.DataSource = new BindingSource(colors, null);
        comboBox1.DisplayMember = "Value";
        comboBox1.ValueMember = "Key"; 

Full Source...Dictionary as a Combobox Datasource

One of the data columns in the excel (Column Id 6) has one or more cell data that exceed the datacolumn datatype length in the database.

Verify the data in excel. Also verify the data in the excel for its format to be in compliance with the database table schema.

To avoid this, try exceeding the data-length of the string datatype in the database table.

Hope this helps.

Since I have been doing a bit of research in that field lately (Jan, '12), the most promising client is actually : WebSocket for Python. It support a normal socket that you can call like this :

ws = EchoClient('http://localhost:9000/ws')

The client can be Threaded or based on IOLoop from Tornado project. This will allow you to create a multi concurrent connection client. Useful if you want to run stress tests.

The client also exposes the onmessage, opened and closed methods. (WebSocket style).

Permanent generation

if you are using extracted tomcat then,

startup.sh and shutdown.sh are two script located in TOMCAT/bin/ to start and shutdown tomcat, You could use that

if tomcat is installed then

/etc/init.d/tomcat5.5 start
/etc/init.d/tomcat5.5 stop
/etc/init.d/tomcat5.5 restart

Because you must add colorControlNormal, colorControlActivated, colorControlHighLight items to main application theme:

<!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>

        <item name="colorControlActivated">@color/yellow_bright</item>
        <item name="colorControlNormal">@color/yellow_black</item>

    </style>

you can use these styles:

style="border-left: 1px solid #cdd0d4;"  
style="border-bottom: 1px solid #cdd0d4;"
style="border-top: 1px solid #cdd0d4;"
style="border-right: 1px solid #cdd0d4;"

with this you want u must use

<td style="border-left: 1px solid #cdd0d4;border-bottom: 1px solid #cdd0d4;">  

or

<img style="border-left: 1px solid #cdd0d4;border-bottom: 1px solid #cdd0d4;"> 

A modification to GUS's example:

$(document).ready(function() {
    var tmpImg = new Image() ;
    tmpImg.onload = function() {
        // Run onload code.
    } ;

tmpImg.src = $('#img').attr('src');
})

Set the source before and after the onload.

Just a simple explanation to use it in an HTML document.

If you have a Map of types (key, array) then you initialise the array this way:

public cityShop: Map<string, Shop[]> = new Map();

And to iterate over it, you create an array from key values.

Just use it as an array as in:

keys = Array.from(this.cityShop.keys());

Then, in HTML, you can use:

*ngFor="let key of keys"

Inside this loop, you just get the array value with:

this.cityShop.get(key)

Done!

"use strict";

Basically it enables the strict mode.

Strict Mode is a feature that allows you to place a program, or a function, in a "strict" operating context. In strict operating context, the method form binds this to the objects as before. The function form binds this to undefined, not the global set objects.

As per your comments you are telling some differences will be there. But it's your assumption. The Node.js code is nothing but your JavaScript code. All Node.js code are interpreted by the V8 JavaScript engine. The V8 JavaScript Engine is an open source JavaScript engine developed by Google for Chrome web browser.

So, there will be no major difference how "use strict"; is interpreted by the Chrome browser and Node.js.

Please read what is strict mode in JavaScript.

For more information:

1. Strict mode
2. ECMAScript 5 Strict mode support in browsers
3. Strict mode is coming to town
4. Compatibility table for strict mode
5. Stack Overflow questions: what does 'use strict' do in JavaScript & what is the reasoning behind it

ECMAScript 6 Code & strict mode. Following is brief from the specification:

10.2.1 Strict Mode Code

An ECMAScript Script syntactic unit may be processed using either unrestricted or strict mode syntax and semantics. Code is interpreted as strict mode code in the following situations:

• Global code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive (see 14.1.1).
• Module code is always strict mode code.
• All parts of a ClassDeclaration or a ClassExpression are strict mode code.
• Eval code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive or if the call to eval is a direct eval (see 12.3.4.1) that is contained in strict mode code.
• Function code is strict mode code if the associated FunctionDeclaration, FunctionExpression, GeneratorDeclaration, GeneratorExpression, MethodDefinition, or ArrowFunction is contained in strict mode code or if the code that produces the value of the function’s [[ECMAScriptCode]] internal slot begins with a Directive Prologue that contains a Use Strict Directive.
• Function code that is supplied as the arguments to the built-in Function and Generator constructors is strict mode code if the last argument is a String that when processed is a FunctionBody that begins with a Directive Prologue that contains a Use Strict Directive.

Additionally if you are lost on what features are supported by your current version of Node.js, this node.green can help you (leverages from the same data as kangax).

You can use COM, or P/Invoke from .Net, to open the Winspool.drv driver and send bytes directly to devices. But you don't want to do that; this typically works only for the one device on the one version of the one driver you test with, and breaks on everything else. Take this from long, painful, personal experience.

What you want to do is get a barcode font or library that draws barcodes using plain old GDI or GDI+ commands; there's one for .Net here. This works on all devices, even after Zebra changes the driver.

fyi The code I ended up with:

IF UPDATE (QtyToRepair)
    begin
        INSERT INTO tmpQtyToRepairChanges (OrderNo, PartNumber, ModifiedDate, ModifiedUser, ModifiedHost, QtyToRepairOld, QtyToRepairNew)
        SELECT S.OrderNo, S.PartNumber, GETDATE(), SUSER_NAME(), HOST_NAME(), D.QtyToRepair, I.QtyToRepair FROM SCHEDULE S
        INNER JOIN Inserted I ON S.OrderNo = I.OrderNo and S.PartNumber = I.PartNumber
        INNER JOIN Deleted D ON S.OrderNo = D.OrderNo and S.PartNumber = D.PartNumber 
        WHERE I.QtyToRepair <> D.QtyToRepair
end

You can skip the ORM, builders, etc. and simplify your DB/SQL management using sqler and sqler-mdb.

-- create this file at: db/mdb/setup/create.database.sql
CREATE DATABASE IF NOT EXISTS sqlermysql

const conf = {
  "univ": {
    "db": {
      "mdb": {
        "host": "localhost",
        "username":"admin",
        "password": "mysqlpassword"
      }
    }
  },
  "db": {
    "dialects": {
      "mdb": "sqler-mdb"
    },
    "connections": [
      {
        "id": "mdb",
        "name": "mdb",
        "dir": "db/mdb",
        "service": "MySQL",
        "dialect": "mdb",
        "pool": {},
        "driverOptions": {
          "connection": {
            "multipleStatements": true
          }
        }
      }
    ]
  }
};

// create/initialize manager
const manager = new Manager(conf);
await manager.init();

// .sql file path is path to db function
const result = await manager.db.mdb.setup.create.database();

console.log('Result:', result);

// after we're done using the manager we should close it
process.on('SIGINT', async function sigintDB() {
  await manager.close();
  console.log('Manager has been closed');
});

The absolute solution that I've recently just tried is:

<input class="class-name" placeholder="1234567" name="elementname"  type="text" maxlength="4" onkeypress="return (event.charCode == 8 || event.charCode == 0 || event.charCode == 13) ? null : event.charCode >= 48 && event.charCode <= 57" />

I am just doing this without even trying it. Would this work?

myDiv = getElementById("myDiv");
myDiv.querySelectorAll(this.id + " > .foo");

Give it a try, maybe it works maybe not. Apolovies, but I am not on a computer now to try it (responding from my iPhone).

DateTime is not standard nullable type. If you want assign null to DateTime type of variable, you have to use DateTime? type which supports null value.

If you only want test your variable to be set (e.g. variable holds other than default value), you can use keyword "default" like in following code:

if (dateTimeVariable == default(DateTime))
{
    //do work for dateTimeVariable == null situation
}

I just have the same problem, just open the task manager, go to services tab and search MySQL_One service, rigth click and start, this works for very good.

Off the top of my head:

• Use GetType() instead of typeof(Page) in order to bind the script to your actual page class instead of the base class,
• Pass a key constant instead of Page.UniqueID, which is not that meaningful since it's supposed to be used by named controls,
• End your Javascript statement with a semicolon,
• Register the script during the PreRender phase:

protected void Page_PreRender(object sender, EventArgs e)
{
    ScriptManager.RegisterStartupScript(this, GetType(), "YourUniqueScriptKey", 
        "alert('This pops up');", true);
}

You have to make the UL inside the div behave like a block. Try adding

.navigation ul {
     display: inline-block;
}

Strip out tags, leave only alphanumeric characters and space:

$clear = preg_replace('/[^a-zA-Z0-9\s]/', '', strip_tags($des));

Edit: all credit to DaveRandom for the perfect solution...

$clear = preg_replace('/[^a-zA-Z0-9\s]/', '', strip_tags(html_entity_decode($des)));

The problem is in your pubspec.yaml, here you need to delete the last comma.

uses-material-design: true,

AssertJ assertions can be used to compare the values without #equals method properly overridden, e.g.:

import static org.assertj.core.api.Assertions.assertThat; 

// ...

assertThat(actual)
    .usingRecursiveComparison()
    .isEqualTo(expected);

I'm going to make some enemies with this, but I actually use -- gasp -- a non-monospace font! I occasionally switch back to a monospace to disambiguate something, but mostly find that a good clean sans-serif font is easiest to read and doesn't waste screen estate.

An IDE with good syntax colouring helps.

php code to handle upload image and also create image from base64 encoded data

<?php
error_reporting(E_ALL);
if(isset($_POST['ImageName'])){
$imgname = $_POST['ImageName'];
$imsrc = base64_decode($_POST['base64']);
$fp = fopen($imgname, 'w');
fwrite($fp, $imsrc);
if(fclose($fp)){
 echo "Image uploaded";
}else{
 echo "Error uploading image";
}
}
?>

You need to add the new line character \n:

console.log('line one \nline two')

would display:

line one

line two

you may be create function before so, update your function again using.

Alter FUNCTION dbo.Afisho_rankimin(@emri_rest int)
RETURNS int
AS
  BEGIN
     Declare @rankimi int
     Select @rankimi=dbo.RESTORANTET.Rankimi
     From RESTORANTET
     Where  dbo.RESTORANTET.ID_Rest=@emri_rest
     RETURN @rankimi
END
GO

SELECT dbo.Afisho_rankimin(5) AS Rankimi
GO

I've been testing this myself, and looking at all the answers on this post and I don't think they answer this question very well. I experimented myself in order to get a good answer (code below). You CAN fire either event with both ActionListener and ItemListener 100% of the time when a state is changed in either a radio button or a check box, or any other kind of Swing item I'm assuming since it is type Object. The ONLY difference I can tell between these two listeners is the type of Event Object that gets returned with the listener is different. AND you get a better event type with a checkbox using an ItemListener as opposed to an ActionListener.

The return types of an ActionEvent and an ItemEvent will have different methods stored that may be used when an Event Type gets fired. In the code below the comments show the difference in .get methods for each Class returned Event type.

The code below sets up a simple JPanel with JRadioButtons, JCheckBoxes, and a JLabel display that changes based on button configs. I set all the RadioButtons and CheckBoxes up with both an Action Listener and an Item Listener. Then I wrote the Listener classes below with ActionListener fully commented because I tested it first in this experiment. You will notice that if you add this panel to a frame and display, all radiobuttons and checkboxes always fire regardless of the Listener type, just comment out the methods in one and try the other and vice versa.

Return Type into the implemented methods is the MAIN difference between the two. Both Listeners fire events the same way. Explained a little better in comment above is the reason a checkbox should use an ItemListener over ActionListener due to the Event type that is returned.

Sorry, I can't add much light into this yet, but I am still digging.

You need to specify the encoding of the InputStreamReader using the Charset parameter.

Charset inputCharset = Charset.forName("ISO-8859-1");
InputStreamReader isr = new InputStreamReader(fis, inputCharset));

This is work for me. i hope to help you.

In Oracle, (+) denotes the "optional" table in the JOIN. So in your query,

SELECT a.id, b.id, a.col_2, b.col_2, ...
FROM a,b
WHERE a.id=b.id(+)

it's a LEFT OUTER JOIN of table 'b' to table 'a'. It will return all data of table 'a' without losing its data when the other side (optional table 'b') has no data.

The modern standard syntax for the same query would be

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a
LEFT JOIN b ON a.id=b.id

or with a shorthand for a.id=b.id (not supported by all databases):

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a
LEFT JOIN b USING(id)

If you remove (+) then it will be normal inner join query

Older syntax, in both Oracle and other databases:

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a,b
WHERE a.id=b.id

More modern syntax:

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a
INNER JOIN b ON a.id=b.id

Or simply:

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a
JOIN b ON a.id=b.id

It will only return all data where both 'a' & 'b' tables 'id' value is same, means common part.

If you want to make your query a Right Join

This is just the same as a LEFT JOIN, but switches which table is optional.

Old Oracle syntax:

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a,b
WHERE a.id(+)=b.id

Modern standard syntax:

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a
RIGHT JOIN b ON a.id=b.id

Left Outer Join using + sign in Oracle 11g

https://www.w3schools.com/sql/sql_join_left.asp

Steps (1) Just Select your range, rows or column or array , (2) Press ctrl+H , (3 a) then in the find type a space (3 b) in the replace do not enter anything, (4)then just click on replace all..... you are done.

The "usual" solution is make a function that return an empty formGroup or a fullfilled formGroup

createFormGroup(data:any)
{
 return this.fb.group({
   user: [data?data.user:null],
   questioning: [data?data.questioning:null, Validators.required],
   questionType: [data?data.questionType, Validators.required],
   options: new FormArray([this.createArray(data?data.options:null])
})
}

//return an array of formGroup
createArray(data:any[]|null):FormGroup[]
{
   return data.map(x=>this.fb.group({
        ....
   })
}

then, in SUBSCRIBE, you call the function

this.qService.editQue([params["id"]]).subscribe(res => {
  this.editqueForm = this.createFormGroup(res);
});

be carefull!, your form must include an *ngIf to avoid initial error

<form *ngIf="editqueForm" [formGroup]="editqueForm">
   ....
</form>

Probably one of the indexes is wrong, either the inner one or the outer one.

I suspect you mean to say [0] where you say [1] and [1] where you say [2]. Indexes are 0-based in Python.

Generally I just use the command line for svn, it's the fastest and easiest way to do it to be honest, I'd recommend you try it.
Before you dismiss this, you should probably ask yourself if there is really any feature that you need a GUI for, and whether you would prefer to open up a GUI app and download the files, or just type svn co svn://site-goes-here.org/trunk

You can easily add, remove, move, commit, copy or update files with simple commands given with svn help, so for most users it is more than enough.

-Xmx<size>        set maximum Java heap size
-Xss<size>        set java thread stack size

If you are using the tomcat server, you can change the heap size by going to Eclipse/Run/Run Configuration and select Apache Tomcat/your_server_name/Arguments and under VM arguments section use the following:

-XX:MaxPermSize=256m
-Xms256m -Xmx512M

If you are not using any server, you can type the following on the command line before you run your code:

java -Xms64m -Xmx256m HelloWorld

More information on increasing the heap size can be found here

MSDN: Configuration Manager.AppSettings

if (ConfigurationManager.AppSettings[name] != null)
{
// Now do your magic..
}

or

string s = ConfigurationManager.AppSettings["myKey"];
if (!String.IsNullOrEmpty(s))
{
    // Key exists
}
else
{
    // Key doesn't exist
}

First add a column in child table Cid as int then alter table with the code below. This way you can add the foreign key Cid as the primary key of parent table and use it as the foreign key in child table ... hope it will help you as it is good for me:

ALTER TABLE [child] 
  ADD CONSTRAINT [CId] 
  FOREIGN KEY ([CId]) 
  REFERENCES [Parent]([CId]) 
  ON DELETE CASCADE ON UPDATE NO ACTION;
GO

My use case was to save range to variable and then select it later on

Dim targetRange As Range
Set targetRange = Sheets("Sheet").Range("Name")
Application.Goto targetRange
Set targetRangeQ = Nothing ' reset

m - sets margin

p - sets padding

t - sets margin-top or padding-top

b - sets margin-bottom or padding-bottom

l - sets margin-left or padding-left

r - sets margin-right or padding-right

x - sets both padding-left and padding-right or margin-left and margin-right

y - sets both padding-top and padding-bottom or margin-top and margin-bottom

blank - sets a margin or padding on all 4 sides of the element

0 - sets margin or padding to 0

1 - sets margin or padding to .25rem (4px if font-size is 16px)

2 - sets margin or padding to .5rem (8px if font-size is 16px)

3 - sets margin or padding to 1rem (16px if font-size is 16px)

4 - sets margin or padding to 1.5rem (24px if font-size is 16px)

5 - sets margin or padding to 3rem (48px if font-size is 16px)

auto - sets margin to auto

Check that you don't have a .my.cnf hiding in your homedir. That was my problem.

To get the value, we can use multiple attributes, one of them being the name attribute. E.g

$("input[name='nameOfElement']").val();

We can also use other attributes to get values

HTML

<input type="text" id="demoText" demo="textValue" />

JS

$("[demo='textValue']").val();

public static String randomSeriesForThreeCharacter() {
    Random r = new Random();
    String value = "";
    char random_Char ;
    for(int i=0; i<10; i++)
    {
        random_Char = (char) (48 + r.nextInt(74));
        value = value + random_char;
    }
    return value;
}

You forgot the C: after the file:///

Nope, you've heard of MonoTouch which is a .NET/mono environment for iPhone development. But you still need a Mac and the official iPhone SDK. And the emulator is the official apple one, this acts as a separate IDE and allows you to not have to code in Objective C, rather you code in c#

It's an interesting project to say the least....

EDIT: apparently, you can distribute on the app store now, early on that was a no go....

It won't be fast, and there will be a lot for you to type (unless you generate the SQL from user_tab_columns), but here is what I use when I need to compare two tables row-by-row and column-by-column.

The query will return all rows that

• Exists in table1 but not in table2
• Exists in table2 but not in table1
• Exists in both tables, but have at least one column with a different value

(common identical rows will be excluded).

"PK" is the column(s) that make up your primary key. "a" will contain A if the present row exists in table1. "b" will contain B if the present row exists in table2.

select pk
      ,decode(a.rowid, null, null, 'A') as a
      ,decode(b.rowid, null, null, 'B') as b
      ,a.col1, b.col1
      ,a.col2, b.col2
      ,a.col3, b.col3
      ,...
  from table1 a 
  full outer 
  join table2 b using(pk)
 where decode(a.col1, b.col1, 1, 0) = 0
    or decode(a.col2, b.col2, 1, 0) = 0
    or decode(a.col3, b.col3, 1, 0) = 0
    or ...;

Edit Added example code to show the difference described in comment. Whenever one of the values contains NULL, the result will be different.

with a as(
   select 0    as col1 from dual union all
   select 1    as col1 from dual union all
   select null as col1 from dual
)
,b as(
   select 1    as col1 from dual union all
   select 2    as col1 from dual union all
   select null as col1 from dual
)   
select a.col1
      ,b.col1
      ,decode(a.col1, b.col1, 'Same', 'Different') as approach_1
      ,case when a.col1 <> b.col1 then 'Different' else 'Same' end as approach_2       
  from a,b
 order 
    by a.col1
      ,b.col1;    




col1   col1_1   approach_1  approach_2
====   ======   ==========  ==========

I just found a great solution for this, and after looking at all the responses so far, I haven't seen it posted yet. So, here's what I did:

I created a CSS Rule for the class and used a pseudo-class of :focus for that rule. I set outline: none to get rid of that default light-blue non-border-radius-able 'outline' that Chrome uses by default. Then, in that same :focus pseudo-class, where that outline no longer exists, I added my radius and border properties. Leading to the following

outline: none;
border-radius: 5px;
border: 2px solid maroon;

to have a maroon-colored outline with a border radius that now appears when the element is tab-selected by the user.

Here is the BESTEST way to send emails using PHPmailer library, this is the only method that works for me.

require_once 'mailer/class.phpmailer.php';
    $mail = new PHPMailer(); // create a new object
    $mail->IsSMTP(); // enable SMTP
    $mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only
    $mail->SMTPAuth = true; // authentication enabled
    $mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for GMail
    $mail->Host = "smtp.gmail.com";
    $mail->Port = 465; // or 587
    $mail->IsHTML(true);
    $mail->Username = "[email protected]";
    $mail->Password = "xxxxxxx";
    $mail->SetFrom("[email protected]");
    $mail->AddAddress($to);
    $logfile = dirname(dirname(__FILE__)) . '/mail.log';
    try {
        $mail->Body = $message;
        $mail->Subject = $subject;


        file_put_contents($logfile, "Content: \n", FILE_APPEND);
        file_put_contents($logfile, $message . "\n\n", FILE_APPEND);

        if(!$mail->Send()) {
            echo "Mailer Error: " . $mail->ErrorInfo;
        } else {
            echo "Email has been sent";
        }
    } catch (Exception $e) {
        #print_r($e->getMessage());
        file_put_contents($logfile, "Error: \n", FILE_APPEND);
        file_put_contents($logfile, $e->getMessage() . "\n", FILE_APPEND);
        file_put_contents($logfile, $e->getTraceAsString() . "\n\n", FILE_APPEND);
    }

Check for scale factor in touchove event then prevent touch event.

document.addEventListener('touchmove', function(event) {
    event = event.originalEvent || event;
    if(event.scale > 1) {
        event.preventDefault();
    }
}, false);

This is a classic difficulty in LaTeX.

The problem is how to do layout with floats (figures and tables, an similar objects) and footnotes. In particular, it is hard to pick a place for a float with certainty that making room for the associated footnotes won't cause trouble. So the standard tabular and figure environments don't even try.

What can you do:

1. Fake it. Just put a hardcoded vertical skip at the bottom of the caption and then write the footnote yourself (use \footnotesize for the size). You also have to manage the symbols or number yourself with \footnotemark. Simple, but not very attractive, and the footnote does not appear at the bottom of the page.
2. Use the tabularx, longtable, threeparttable[x] (kudos to Joseph) or ctable which support this behavior.
3. Manage it by hand. Use [h!] (or [H] with the float package) to control where the float will appear, and \footnotetext on the same page to put the footnote where you want it. Again, use \footnotemark to install the symbol. Fragile and requires hand-tooling every instance.
4. The footnotes package provides the savenote environment, which can be used to do this.
5. Minipage it (code stolen outright, and read the disclaimer about long caption texts in that case):

    \begin{figure}
      \begin{minipage}{\textwidth}
        ...
        \caption[Caption for LOF]%
          {Real caption\footnote{blah}}
      \end{minipage}
    \end{figure}

In JavaScript, == is pronounced "Probably Equals".

What I mean by that is that JavaScript will automatically convert the Boolean into an integer and then attempt to compare the two sides.

For real equality, use the === operator.

Just for the sake of adding functions to the Date prototype:

In a mutable fashion / style:

Date.prototype.addDays = function(n) {
   this.setDate(this.getDate() + n);
};

// Can call it tomorrow if you want
Date.prototype.nextDay = function() {
   this.addDays(1);
};

Date.prototype.addMonths = function(n) {
   this.setMonth(this.getMonth() + n);
};

Date.prototype.addYears = function(n) {
   this.setFullYear(this.getFullYear() + n);
}

// etc...

var currentDate = new Date();
currentDate.nextDay();

You typically have to do this in a single syscall, or else you will get a race condition.

This will open for reading and writing, creating the file if necessary.

FILE *fp = fopen("scores.dat", "ab+");

If you want to read it and then write a new version from scratch, then do it as two steps.

FILE *fp = fopen("scores.dat", "rb");
if (fp) {
    read_scores(fp);
}

// Later...

// truncates the file
FILE *fp = fopen("scores.dat", "wb");
if (!fp)
    error();
write_scores(fp);

The data received in your serialPort1_DataReceived method is coming from another thread context than the UI thread, and that's the reason you see this error.
To remedy this, you will have to use a dispatcher as descibed in the MSDN article:
How to: Make Thread-Safe Calls to Windows Forms Controls

So instead of setting the text property directly in the serialport1_DataReceived method, use this pattern:

delegate void SetTextCallback(string text);

private void SetText(string text)
{
  // InvokeRequired required compares the thread ID of the
  // calling thread to the thread ID of the creating thread.
  // If these threads are different, it returns true.
  if (this.textBox1.InvokeRequired)
  { 
    SetTextCallback d = new SetTextCallback(SetText);
    this.Invoke(d, new object[] { text });
  }
  else
  {
    this.textBox1.Text = text;
  }
}

So in your case:

private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
{
  txt += serialPort1.ReadExisting().ToString();
  SetText(txt.ToString());
}

Yet another version of the same kind of control. It has similar functionality as the others, but it adds:

1. Touch support (drag/pinch)
2. The image can be deleted (normally, the Image control locks the image on disk, so you cannot delete it).
3. An inner border child, so the panned image doesn't overlap the border. In case of borders with rounded rectangles, look for ClippedBorder classes.

Usage is simple:

<Controls:ImageViewControl ImagePath="{Binding ...}" />

And the code:

public class ImageViewControl : Border
{
    private Point origin;
    private Point start;
    private Image image;

    public ImageViewControl()
    {
        ClipToBounds = true;
        Loaded += OnLoaded;
    }

        var newImagePath = target.ImagePath;
        target.ReloadImage(newImagePath);
        target.OnImagePathChanged(oldImagePath, newImagePath);

CSS has a text-align: center property, and since this is purely a visual thing, not semantic, it should be relegated to CSS, not HTML.

An old thread, but a useful one... so here's some additional code.

First, in response to Craig's point about the regex being overly greedy and failing for sheet names containing a single quote, this should do the trick (replace 'SHEETNAME'!A1 with your own sheet & cell reference):

=IF(TODAY()=TODAY(), SUBSTITUTE(REGEXREPLACE(CELL("address",'SHEETNAME'!A1),"'?(.+?)'?!\$.*","$1"),"''","'", ""), "")

It uses a lazy match (the ".+?") to find a character string (squotes included) that may or may not be enclosed by squotes but is definitely terminated by bang dollar ("!$") followed by any number of characters. Google Sheets actually protects squotes within a sheet name by appending another squote (as in ''), so the SUBSTITUTE is needed to reduce these back to single squotes.

The formula also allows for sheet names that contain bangs ("!"), but will fail for names using bang dollars ("!$") - if you really need to make your sheet names to look like full absolute cell references then put a separating character between the bang and the dollar (such as a space).

Note that it will only work correctly when pointed at a different sheet from the one that the formula resides! This is because CELL("address" returns just the cell reference (not the sheet name) when used on the same sheet. If you need a sheet to show its own name then put the formula in a cell on another sheet, point it at your target sheet, and then reference the formula cell from the target sheet. I often have a "Meta" sheet in my workbooks to hold settings, common values, database matching criteria, etc so that's also where I put this formula.

As others have said many times above, Google Sheets will only notice changes to the sheet name if you set the workbook's recalculation to "On change and every minute" which you can find on the File|Settings|Calculation menu. It can take up to a whole minute for the change to be picked up.

Secondly, if like me you happen to need an inter-operable formula that works on both Google Sheets and Excel (which for older versions at least doesn't have the REGEXREPLACE function), try:

=IF(IFERROR(INFO("release"), 0)=0, IF(TODAY()=TODAY(), SUBSTITUTE(REGEXREPLACE(CELL("address",'SHEETNAME'!A1),"'?(.+?)'?!\$.*","$1"),"''","'", ""), ""), MID(CELL("filename",'SHEETNAME'!A1),FIND("]",CELL("filename",'SHEETNAME'!A1))+1,255))

This uses INFO("release") to determine which platform we are on... Excel returns a number >0 whereas Google Sheets does not implement the INFO function and generates an error which the formula traps into a 0 and uses for numerical comparison. The Google code branch is as above.

For clarity and completeness, this is the Excel-only version (which does correctly return the name of the sheet it resides on):

=MID(CELL("filename",'SHEETNAME'!A1),FIND("]",CELL("filename",'SHEETNAME'!A1))+1,255)

It looks for the "]" filename terminator in the output of CELL("filename" and extracts the sheet name from the remaining part of the string using the MID function. Excel doesn't allow sheet names to contain "]" so this works for all possible sheet names. In the inter-operable version, Excel is happy to be fed a call to the non-existent REGEXREPLACE function because it never gets to execute the Google code branch.

Answered here. But posting it again for reference.

window.open() will not open in new tab if it is not happening on actual click event. In the example given the url is being opened on actual click event. This will work provided user has appropriate settings in the browser.

<a class="link">Link</a>
<script  type="text/javascript">
     $("a.link").on("click",function(){
         window.open('www.yourdomain.com','_blank');
     });
</script>

Similarly, if you are trying to do an ajax call within the click function and want to open a window on success, ensure you are doing the ajax call with async : false option set.

Gradle is one type of build tool that builds the source code of the program. So it's an important part of Android Studio, and needs to be installed before starting developing your application.

We do not have to install it separately, because the Android Studio does it for us, when we make our first project.

You can use join with pop + tolist. Performance is comparable to concat with drop + tolist, but some may find this syntax cleaner:

res = df.join(pd.DataFrame(df.pop('b').tolist()))

Benchmarking with other methods:

df = pd.DataFrame({'a':[1,2,3], 'b':[{'c':1}, {'d':3}, {'c':5, 'd':6}]})

def joris1(df):
    return pd.concat([df.drop('b', axis=1), df['b'].apply(pd.Series)], axis=1)

def joris2(df):
    return pd.concat([df.drop('b', axis=1), pd.DataFrame(df['b'].tolist())], axis=1)

def jpp(df):
    return df.join(pd.DataFrame(df.pop('b').tolist()))

df = pd.concat([df]*1000, ignore_index=True)

%timeit joris1(df.copy())  # 1.33 s per loop
%timeit joris2(df.copy())  # 7.42 ms per loop
%timeit jpp(df.copy())     # 7.68 ms per loop

Yes it is possible. I have been doing that all the while.

dynamic Obj = JsonConvert.DeserializeObject(<your json string>);

It is a bit trickier for non native type. Suppose inside your Obj, there is a ClassA, and ClassB objects. They are all converted to JObject. What you need to do is:

ClassA ObjA = Obj.ObjA.ToObject<ClassA>();
ClassB ObjB = Obj.ObjB.ToObject<ClassB>();

I think it suffices to hand the data over directly:

$("#inputhidden").select2("data", data, true);

Note that the second parameter seems to indicate that a refresh is desired.

Thanks to @Bergi for help with this.

If that doesn't automatically update you could either try calling it's updateResults method directly.

$("#inputhidden").select2("updateResults");

Or trigger it indirectly by sending a trigger to the "input.select2-input" like so:

var search = $("#inputhidden input.select2-input");
search.trigger("input");

The answer is in the error message. In the past you or a process did a sudo pip and that caused some of the directories under /Library/Python/2.7/site-packages/... to have permissions that make it unaccessable to your current user.

Then you did a pip install whatever which relies on the other thing.

So to fix it, visit the /Library/Python/2.7/site-packages/... and find the directory with the root or not-your-user permissions and either remove then reinstall those packages, or just force ownership to the user to whom ought to have access.

Super easy and works, but not sure why....

angular.module('testing')
  .directive('details', function () {
        return {
              templateUrl: 'components/details.template.html',
              restrict: 'E',                 
              controller: function ($scope) {
                    $scope.details=$scope.details;  <=== can see the parent details doing this                     
              }
        };
  });

You are using an immutable list. The operations on the List return a new List. The old List remains unchanged. This can be very useful if another class / method holds a reference to the original collection and is relying on it remaining unchanged. You can either use different named vals as in

val myList1 = 1.0 :: 5.5 :: Nil 
val myList2 = 2.2 :: 3.7 :: mylist1

or use a var as in

var myList = 1.0 :: 5.5 :: Nil 
myList :::= List(2.2, 3.7)

This is equivalent syntax for:

myList = myList.:::(List(2.2, 3.7))

Or you could use one of the mutable collections such as

val myList = scala.collection.mutable.MutableList(1.0, 5.5)
myList.++=(List(2.2, 3.7))

Not to be confused with the following that does not modify the original mutable List, but returns a new value:

myList.++:(List(2.2, 3.7))

However you should only use mutable collections in performance critical code. Immutable collections are much easier to reason about and use. One big advantage is that immutable List and scala.collection.immutable.Vector are Covariant. Don't worry if that doesn't mean anything to you yet. The advantage of it is you can use it without fully understanding it. Hence the collection you were using by default is actually scala.collection.immutable.List its just imported for you automatically.

I tend to use List as my default collection. From 2.12.6 Seq defaults to immutable Seq prior to this it defaulted to immutable.

You could use...

<option <?= ($temp == $value) ? "SELECTED" : "" ?> >$value</opton>

Edit: I thought I was looking at PHP questions... Sorry.

I know this is 8 years old, but no one seems to have actually read and answered the question.

You can call .values() on a dict to get a list of the inner dicts and thus access them by index.

>>> mydict = {
...  'Apple': {'American':'16', 'Mexican':10, 'Chinese':5},
...  'Grapes':{'Arabian':'25','Indian':'20'} }

>>>mylist = list(mydict.values())
>>>mylist[0]
{'American':'16', 'Mexican':10, 'Chinese':5},
>>>mylist[1]
{'Arabian':'25','Indian':'20'}

>>>myInnerList1 = list(mylist[0].values())
>>>myInnerList1
['16', 10, 5]
>>>myInnerList2 = list(mylist[1].values())
>>>myInnerList2
['25', '20']

Make sure you have the last version for youtube-dl

sudo youtube-dl -U

after that you can solve this problem by installing the missing ffmpeg on ubuntu and debian:

sudo apt-get install ffmpeg

and macOS use the command:

brew install ffmpeg

From the de-compiled sources of Android 3.2's framework-res.apk, res/values/styles.xml contains:

<style name="Theme.Holo">
    <!-- ... -->
    <item name="actionBarSize">56.0dip</item>
    <!-- ... -->
</style>

3.0 and 3.1 seem to be the same (at least from AOSP)...

I'm not familiar with the package WriteXLS; I generally use XLConnect:

library(XLConnect)
##
newWB <- loadWorkbook(
  filename="F:/TempDir/tempwb.xlsx",
  create=TRUE)
##
for(i in 1:10){
  wsName <- paste0("newsheet",i)
  createSheet(
    newWB,
    name=wsName)
  ##
  writeWorksheet(
    newWB,
    data=data.frame(
      X=1:10,
      Dataframe=paste0("DF ",i)),
    sheet=wsName,
    header=TRUE,
    rownames=NULL)
}
saveWorkbook(newWB)

This can certainly be vectorized, as @joran noted above, but just for the sake of generating dynamic sheet names quickly, I used a for loop to demonstrate.

I used the create=TRUE argument in loadWorkbook since I was creating a new .xlsx file, but if your file already exists then you don't have to specify this, as the default value is FALSE.

Here are a few screenshots of the created workbook:

you can use the special package "checkinstall" for all packages which are not even in debian/ubuntu yet.

You can use "uupdate" (apt-get install devscripts) to build a package from source with existing debian sources:

Example for libdrm2:

apt-get build-dep libdrm2
apt-get source libdrm2
cd libdrm-2.3.1
uupdate ~/Downloads/libdrm-2.4.1.tar.gz
cd ../libdrm-2.4.1
dpkg-buildpackage -us -uc -nc

This is over simplifying it, but Express.js is to Node.js what Ruby on Rails or Sinatra is to Ruby.

Express 3.x is a light-weight web application framework to help organize your web application into an MVC architecture on the server side. You can use a variety of choices for your templating language (like EJS, Jade, and Dust.js).

You can then use a database like MongoDB with Mongoose (for modeling) to provide a backend for your Node.js application. Express.js basically helps you manage everything, from routes, to handling requests and views.

Redis is a key/value store -- commonly used for sessions and caching in Node.js applications. You can do a lot more with it, but that's what I'm using it for. I use MongoDB for more complex relationships, like line-item <-> order <-> user relationships. There are modules (most notably connect-redis) that will work with Express.js. You will need to install the Redis database on your server.

Here is a link to the Express 3.x guide: https://expressjs.com/en/3x/api.html

This is how I do it in TypeScript:

const index = this.array.indexOf(this.objectToReplace);
this.array[index] = newObject;

NVM Installation & usage on Windows

Below are the steps for NVM Installation on Windows:

NVM stands for node version manager, which will help to switch between node versions while also allowing to work with multiple npm versions.

• Install nvm setup.
• Use command nvm list to check list of installed node versions.
• Example: Type nvm use 6.9.3 to switch versions.

The first question you need to ask is whether you really need the ID to be random. Sometime, sequential IDs are good enough.

Now, if you do need it to be random, we first note a generated sequence of numbers that contain no duplicates can not be called random. :p Now that we get that out of the way, the fastest way to do this is to have a Hashtable or HashMap containing all the IDs already generated. Whenever a new ID is generated, check it against the hashtable, re-generate if the ID already occurs. This will generally work well if the number of students is much less than the range of the IDs. If not, you're in deeper trouble as the probability of needing to regenerate an ID increases, P(generate new ID) = number_of_id_already_generated / number_of_all_possible_ids. In this case, check back the first paragraph (do you need the ID to be random?).

Hope this helps.

If you want to read a zipped or a tar.gz file into pandas dataframe, the read_csv methods includes this particular implementation.

df = pd.read_csv('filename.zip')

Or the long form:

df = pd.read_csv('filename.zip', compression='zip', header=0, sep=',', quotechar='"')

Description of the compression argument from the docs:

compression : {‘infer’, ‘gzip’, ‘bz2’, ‘zip’, ‘xz’, None}, default ‘infer’ For on-the-fly decompression of on-disk data. If ‘infer’ and filepath_or_buffer is path-like, then detect compression from the following extensions: ‘.gz’, ‘.bz2’, ‘.zip’, or ‘.xz’ (otherwise no decompression). If using ‘zip’, the ZIP file must contain only one data file to be read in. Set to None for no decompression.

New in version 0.18.1: support for ‘zip’ and ‘xz’ compression.

Here are two options to emulate the needed behavior. Not a general solution, but may help in some cases. The vertical spacing here is calculated on the basis of the size of the outer element, not its parent, but this size itself can be relative to the parent and this way the spacing will be relative too.

<div id="outer">
    <div id="inner">
        content
    </div>
</div>

First option: use pseudo-elements, here vertical and horizontal spacing are relative to the outer. Demo

#outer::before, #outer::after {
    display: block;
    content: "";
    height: 10%;
}
#inner {
    height: 80%;
    margin-left: 10%;
    margin-right: 10%;
}

Moving the horizontal spacing to the outer element makes it relative to the parent of the outer. Demo

#outer {
    padding-left: 10%;
    padding-right: 10%;
}

Second option: use absolute positioning. Demo

#outer {
    position: relative;
}
#inner {
    position: absolute;
    left: 10%;
    right: 10%;
    top: 10%;
    bottom: 10%;
}

TLDR:

CREATE TABLE MyTable(
    a int NOT NULL
    ,b smallint NOT NULL index IX_indexName nonclustered
    ,c smallint NOT NULL
    ,d smallint NOT NULL
    ,e smallint NOT NULL
)

Details

As per T-SQL CREATE TABLE documentation, in 2014 the column definition supports defining an index:

<column_definition> ::=  
column_name <data_type>  
    ...
    [ <column_index> ]  

and <column_index> grammar is defined as:

<column_index> ::=   
 INDEX index_name [ CLUSTERED | NONCLUSTERED ]  
    [ WITH ( <index_option> [ ,... n ] ) ]  
    [ ON { partition_scheme_name (column_name )   
         | filegroup_name  
         | default   
         }  
    ]   
    [ FILESTREAM_ON { filestream_filegroup_name | partition_scheme_name | "NULL" } ]  
  

So a lot of what you can do as a separate statement can be done inline. I noticed include is not an option in this grammar so some things are not possible.

CREATE TABLE MyTable(
    a int NOT NULL
    ,b smallint NOT NULL index IX_indexName nonclustered
    ,c smallint NOT NULL
    ,d smallint NOT NULL
    ,e smallint NOT NULL
)

You can also have inline indexes defined as another line after columns, but within the create table statement, and this allows multiple columns in the index, but still no include clause:

< table_index > ::=   
{  
    {  
      INDEX index_name [ CLUSTERED | NONCLUSTERED ]   
         (column_name [ ASC | DESC ] [ ,... n ] )   
    | INDEX index_name CLUSTERED COLUMNSTORE  
    | INDEX index_name [ NONCLUSTERED ] COLUMNSTORE (column_name [ ,... n ] )  
    }  
    [ WITH ( <index_option> [ ,... n ] ) ]   
    [ ON { partition_scheme_name (column_name )   
         | filegroup_name  
         | default   
         }  
    ]   
    [ FILESTREAM_ON { filestream_filegroup_name | partition_scheme_name | "NULL" } ]  
  
}   

For example here we add an index on both columns c and d:

CREATE TABLE MyTable(
    a int NOT NULL
    ,b smallint NOT NULL index IX_MyTable_b nonclustered
    ,c smallint NOT NULL
    ,d smallint NOT NULL
    ,e smallint NOT NULL

    ,index IX_MyTable_c_d nonclustered (c,d)
)

If you have control over class loading, you can do static initializing from there.

Example:

class MyClass { public static function static_init() { } }

in your class loader, do the following:

include($path . $klass . PHP_EXT);
if(method_exists($klass, 'static_init')) { $klass::staticInit() }

A more heavy weight solution would be to use an interface with ReflectionClass:

interface StaticInit { public static function staticInit() { } }
class MyClass implements StaticInit { public static function staticInit() { } }

in your class loader, do the following:

$rc = new ReflectionClass($klass);
if(in_array('StaticInit', $rc->getInterfaceNames())) { $klass::staticInit() }

The easiest way would be to create a new (simple) Maven project using the "new project" wizard. You can then migrate your source into the Maven folder structure + the auto generated POM file.

If you haven't already committed your changes, just use git checkout to move to the new branch and then commit them normally - changes to files are not tied to a particular branch until you commit them.

If you have already committed your changes:

1. Type git log and remember the SHA of the commit you want to move.
2. Check out the branch you want to move the commit to.
3. Type git cherry-pick SHA substituting the SHA from above.
4. Switch back to your original branch.
5. Use git reset HEAD~1 to reset back before your wrong-branch commit.

cherry-pick takes a given commit and applies it to the currently checked-out head, thus allowing you to copy the commit over to a new branch.

It is looks stupid for me. But I had been in the same situation and I did revert for reverted commits. I did number reverts so I had to do revert for each 'revert commit'.

Now my commits history looks a weird a bit.

It is a pet project so it is OK. But for real-life project I would give preference to go to last commit before reverted restore all reverted code together in one commit and more reasonable comment.

When using the maven-surefire-plugin or maven-failsafe-plugin you must not use a forkCount of 0 or set the forkMode to never as this would prevent the execution of the tests with the javaagent set and no coverage would be recorded.
