Since no one else has given a direct answer to the question that was asked, I'll do it.

The answer is that with POSIX grep, it's impossible to literally satisfy this request:

grep "<Regex for 'doesn't contain hede'>" input

The reason is that POSIX grep is only required to work with Basic Regular Expressions, which are simply not powerful enough for accomplishing that task (they are not capable of parsing all regular languages, because of lack of alternation).

However, GNU grep implements extensions that allow it. In particular, \| is the alternation operator in GNU's implementation of BREs. If your regular expression engine supports alternation, parentheses and the Kleene star, and is able to anchor to the beginning and end of the string, that's all you need for this approach. Note however that negative sets [^ ... ] are very convenient in addition to those, because otherwise, you need to replace them with an expression of the form (a|b|c| ... ) that lists every character that is not in the set, which is extremely tedious and overly long, even more so if the whole character set is Unicode.

Thanks to formal language theory, we get to see how such an expression looks like. With GNU grep, the answer would be something like:

grep "^\([^h]\|h\(h\|eh\|edh\)*\([^eh]\|e[^dh]\|ed[^eh]\)\)*\(\|h\(h\|eh\|edh\)*\(\|e\|ed\)\)$" input

(found with Grail and some further optimizations made by hand).

You can also use a tool that implements Extended Regular Expressions, like egrep, to get rid of the backslashes:

egrep "^([^h]|h(h|eh|edh)*([^eh]|e[^dh]|ed[^eh]))*(|h(h|eh|edh)*(|e|ed))$" input

Here's a script to test it (note it generates a file testinput.txt in the current directory). Several of the expressions presented fail this test.

#!/bin/bash
REGEX="^\([^h]\|h\(h\|eh\|edh\)*\([^eh]\|e[^dh]\|ed[^eh]\)\)*\(\|h\(h\|eh\|edh\)*\(\|e\|ed\)\)$"

# First four lines as in OP's testcase.
cat > testinput.txt <<EOF
hoho

EOF
diff -s -u <(grep -v hede testinput.txt) <(grep "$REGEX" testinput.txt)

In my system it prints:

Files /dev/fd/63 and /dev/fd/62 are identical

as expected.

For those interested in the details, the technique employed is to convert the regular expression that matches the word into a finite automaton, then invert the automaton by changing every acceptance state to non-acceptance and vice versa, and then converting the resulting FA back to a regular expression.

As everyone has noted, if your regular expression engine supports negative lookahead, the regular expression is much simpler. For example, with GNU grep:

grep -P '^((?!hede).)*$' input

However, this approach has the disadvantage that it requires a backtracking regular expression engine. This makes it unsuitable in installations that are using secure regular expression engines like RE2, which is one reason to prefer the generated approach in some circumstances.

Using Kendall Hopkins' excellent FormalTheory library, written in PHP, which provides a functionality similar to Grail, and a simplifier written by myself, I've been able to write an online generator of negative regular expressions given an input phrase (only alphanumeric and space characters currently supported): http://www.formauri.es/personal/pgimeno/misc/non-match-regex/

For hede it outputs:

^([^h]|h(h|e(h|dh))*([^eh]|e([^dh]|d[^eh])))*(h(h|e(h|dh))*(ed?)?)?$

which is equivalent to the above.

Assuming you only want to disallow strings that match the regex completely (i.e., mmbla is okay, but mm isn't), this is what you want:

^(?!(?:m{2}|t)$).*$

(?!(?:m{2}|t)$) is a negative lookahead; it says "starting from the current position, the next few characters are not mm or t, followed by the end of the string." The start anchor (^) at the beginning ensures that the lookahead is applied at the beginning of the string. If that succeeds, the .* goes ahead and consumes the string.

FYI, if you're using Java's matches() method, you don't really need the the ^ and the final $, but they don't do any harm. The $ inside the lookahead is required, though.

In .NET you can use grouping to your advantage like this:

http://regexhero.net/tester/?id=65b32601-2326-4ece-912b-6dcefd883f31

You'll notice that:

(ABC)|(.)

Will grab everything except ABC in the 2nd group. Parenthesis surround each group. So (ABC) is group 1 and (.) is group 2.

So you just grab the 2nd group like this in a replace:

$2

Or in .NET look at the Groups collection inside the Regex class for a little more control.

You should be able to do something similar in most other regex implementations as well.

UPDATE: I found a much faster way to do this here: http://regexhero.net/tester/?id=997ce4a2-878c-41f2-9d28-34e0c5080e03

It still uses grouping (I can't find a way that doesn't use grouping). But this method is over 10X faster than the first.

Wouldn't it be significantly more readable to do a positive match and reject those strings - rather than match the negative to find strings to accept?

/^my/

".*[^(\\.inc)]\\.ftl$"

In Java this will find all files ending in ".ftl" but not ending in ".inc.ftl", which is exactly what I wanted.

The following should work for you:

[\n\r].*Object Name:\s*([^\n\r]*)

Working example

Your desired match will be in capture group 1.

[\n\r][ \t]*Object Name:[ \t]*([^\n\r]*)

Would be similar but not allow for things such as " blah Object Name: blah" and also make sure that not to capture the next line if there is no actual content after "Object Name:"

Here you go:

^[^<>]*$

This will test for string that has no < and no >

If you want to test for a string that may have < and >, but must also have something other you should use just

[^<>] (or ^.*[^<>].*$)

Where [<>] means any of < or > and [^<>] means any that is not of < or >.

And of course the mandatory link.

If you look at Twitter's own container-app.html demo on GitHub, you'll get some ideas on using borders with their grid.

For example, here's the extracted part of the building blocks to their 940-pixel wide 16-column grid system:

.row {
    zoom: 1;
    margin-left: -20px;
}

.row > [class*="span"] {
    display: inline;
    float: left;
    margin-left: 20px;
}

.span4 {
    width: 220px;
}

To allow for borders on specific elements, they added embedded CSS to the page that reduces matching classes by enough amount to account for the border(s).

For example, to allow for the left border on the sidebar, they added this CSS in the <head> after the the main <link href="../bootstrap.css" rel="stylesheet">.

.content .span4 {
    margin-left: 0;
    padding-left: 19px;
    border-left: 1px solid #eee;
}

You'll see they've reduced padding-left by 1px to allow for the addition of the new left border. Since this rule appears later in the source order, it overrides any previous or external declarations.

I'd argue this isn't exactly the most robust or elegant approach, but it illustrates the most basic example.

In C++, variable length arrays are not legal. G++ allows this as an "extension" (because C allows it), so in G++ (without being -pedantic about following the C++ standard), you can do:

int n = 10;
double a[n]; // Legal in g++ (with extensions), illegal in proper C++

If you want a "variable length array" (better called a "dynamically sized array" in C++, since proper variable length arrays aren't allowed), you either have to dynamically allocate memory yourself:

int n = 10;
double* a = new double[n]; // Don't forget to delete [] a; when you're done!

Or, better yet, use a standard container:

int n = 10;
std::vector<double> a(n); // Don't forget to #include <vector>

If you still want a proper array, you can use a constant, not a variable, when creating it:

const int n = 10;
double a[n]; // now valid, since n isn't a variable (it's a compile time constant)

Similarly, if you want to get the size from a function in C++11, you can use a constexpr:

constexpr int n()
{
    return 10;
}

double a[n()]; // n() is a compile time constant expression

Yes, the first means "match all strings that start with a letter", the second means "match all strings that contain a non-letter". The caret ("^") is used in two different ways, one to signal the start of the text, one to negate a character match inside square brackets.

The shortest way:

Console.WriteLine("Press ESC to stop");

while (!(Console.KeyAvailable && Console.ReadKey(true).Key == ConsoleKey.Escape))
{
    // do something
}

Console.ReadKey() is a blocking function, it stops the execution of the program and waits for a key press, but thanks to checking Console.KeyAvailable first, the while loop is not blocked, but running until the Esc is pressed.

we can also use interface for same as broadcastManger here i am sharing the testd code for broadcastManager but by interface.

first make an interface like:

public interface MyInterface {
     void GetName(String name);
}

2-this is the first class that need implementation

public class First implements MyInterface{

    MyInterface interfc;    
    public static void main(String[] args) {
      First f=new First();      
      Second s=new Second();
      f.initIterface(s);
      f.GetName("Paddy");
  }
  private void initIterface(MyInterface interfc){
    this.interfc=interfc;
  }
  public void GetName(String name) {
    System.out.println("first "+name);
    interfc.GetName(name);  
  }
}

3-here is the the second class that implement the same interface whose method call automatically

public class Second implements MyInterface{
   public void GetName(String name) {
     System.out.println("Second"+name);
   }
}

so by this approach we can use the interface functioning same as broadcastManager.

document.getElementById('textbox-id').readOnly=true should work

You can use * operator to unpack dict_values:

>>> d = {1: "a", 2: "b"}
>>> [*d.values()]
['a', 'b']

or list object

>>> d = {1: "a", 2: "b"}
>>> list(d.values())
['a', 'b']

If you want a nice slow animation scroll, for any anchor with href="#bottom" this will scroll you to the bottom:

$("a[href='#bottom']").click(function() {
  $("html, body").animate({ scrollTop: $(document).height() }, "slow");
  return false;
});

Feel free to change the selector.

For those with a non-US keyboard:

File > Preferences > Keyboard Shortcuts. 
(Code > Preferences > Keyboard Shortcuts on Mac)

shows the current key bindings. See also here: https://code.visualstudio.com/docs/getstarted/keybindings

Your code should work just as you expect it to if you add @classmethod decorators.

@classmethod 
def setup_class(cls):
    "Runs once per class"

@classmethod 
def teardown_class(cls):
    "Runs at end of class"

See http://pythontesting.net/framework/pytest/pytest-xunit-style-fixtures/

You can use Sort

List<string> ListaServizi = new List<string>() { };
ListaServizi.Sort();

This is code for the convert PX to SP format. 100% Works

view.setTextSize(TypedValue.COMPLEX_UNIT_PX, 24);

In cases where you know the object is just a Boolean, Date, String, number etc... The javascript String() function works just fine. I recently found this useful in dealing with values coming from jquery's $.each function.

For example the following would convert all items in "value" to a string:

$.each(this, function (name, value) {
  alert(String(value));
});

More details here:

If all you are doing is replacing the existing data, then you can do this

std::vector<int> data; // evil global :)

void CopyData(int *newData, size_t count)
{
   data.assign(newData, newData + count);
}

Dijkstra's algorithm assumes paths can only become 'heavier', so that if you have a path from A to B with a weight of 3, and a path from A to C with a weight of 3, there's no way you can add an edge and get from A to B through C with a weight of less than 3.

This assumption makes the algorithm faster than algorithms that have to take negative weights into account.

You need to get the HLS m3u8 playlist files from the video's manifest. There are ways to do this by hand, but for simplicity I'll be using the youtube-dl tool to get this information. I'll be using this live stream as an example: https://www.youtube.com/watch?v=_Gtc-GtLlTk

Here is how I do it in Python with Selenium 2.48.0:

Show the difference between local and remote tags:

diff <(git tag | sort) <( git ls-remote --tags origin | cut -f2 | grep -v '\^' | sed 's#refs/tags/##' | sort)

• git tag gives the list of local tags
• git ls-remote --tags gives the list of full paths to remote tags
• cut -f2 | grep -v '\^' | sed 's#refs/tags/##' parses out just the tag name from list of remote tag paths
• Finally we sort each of the two lists and diff them

The lines starting with "< " are your local tags that are no longer in the remote repo. If they are few, you can remove them manually one by one, if they are many, you do more grep-ing and piping to automate it.

strstr(request, "favicon") != NULL

if (System.IO.File.Exists(@"C:\test.txt"))

but

System.IO.File.Delete(@"C:\test.txt");

will do the same as long as the folder exists.

• I have the same error as this topic when I restore a new database using an old database. (using .bak gives the same error)

• I Changed the name of old database by name of new database (same this picture). It worked.

Since the request module that other answers use has been deprecated, may I suggest switching to node-fetch:

const fetch = require("node-fetch")

const url = "https://www.googleapis.com/urlshortener/v1/url"
const payload = { longUrl: "http://www.google.com/" }

const res = await fetch(url, {
  method: "post",
  body: JSON.stringify(payload),
  headers: { "Content-Type": "application/json" },
})

const { id } = await res.json()

if ($("input[name='html_elements']:checked").size()==0) {
   alert('Nothing is checked!');
}
else {
  alert('One of the radio buttons is checked!');
}

if you still need to use the double-colon then make sure your on PHP 5.3+

If you don't see log4net.dll in %systemdrive%\windows\assembly\ on the machine you are attempting to deploy it on, it is likely you haven't successfully installed the redistributable for Crystal Reports for .Net Framework 4.0

I ended up writing a function that has worked for me well so far:

  $gettype = gettype($data);

  if (isset($label)) {
    if ($CLI) { $label = $label . ': '; }
    else { $label = '<b>'.$label.'</b>: '; }

// Usage

out('Hello world!');

$var = 'Hello Stackoverflow!';
out($var, 'Label');

All fields in JavaScript (and in TypeScript) can have the value null or undefined.

You can make the field optional which is different from nullable.

interface Employee1 {
    name: string;
    salary: number;
}

var a: Employee1 = { name: 'Bob', salary: 40000 }; // OK
var b: Employee1 = { name: 'Bob' }; // Not OK, you must have 'salary'
var c: Employee1 = { name: 'Bob', salary: undefined }; // OK
var d: Employee1 = { name: null, salary: undefined }; // OK

// OK
class SomeEmployeeA implements Employee1 {
    public name = 'Bob';
    public salary = 40000;
}

// Not OK: Must have 'salary'
class SomeEmployeeB implements Employee1 {
    public name: string;
}

Compare with:

interface Employee2 {
    name: string;
    salary?: number;
}

var a: Employee2 = { name: 'Bob', salary: 40000 }; // OK
var b: Employee2 = { name: 'Bob' }; // OK
var c: Employee2 = { name: 'Bob', salary: undefined }; // OK
var d: Employee2 = { name: null, salary: 'bob' }; // Not OK, salary must be a number

// OK, but doesn't make too much sense
class SomeEmployeeA implements Employee2 {
    public name = 'Bob';
}

The code (C#) bellow ensures that the target element is displayed:

        internal static bool ElementIsDisplayed()
        {
          IWebDriver driver = new ChromeDriver();
          driver.Url = "http://www.seleniumhq.org/docs/04_webdriver_advanced.jsp";
          WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
          By locator = By.CssSelector("input[value='csharp']:first-child");
          IWebElement myDynamicElement = wait.Until<IWebElement>((d) =>
          {
            return d.FindElement(locator);
          });
          return myDynamicElement.Displayed;
        }

If the page supports jQuery it can be used the jQuery.active function to ensure that the target element is retrieved after all the ajax calls are finished:

 public static bool ElementIsDisplayed()
    {
        IWebDriver driver = new ChromeDriver();
        driver.Url = "http://www.seleniumhq.org/docs/04_webdriver_advanced.jsp";
        WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
        By locator = By.CssSelector("input[value='csharp']:first-child");
        return wait.Until(d => ElementIsDisplayed(d, locator));
    }

    public static bool ElementIsDisplayed(IWebDriver driver, By by)
    {
        try
        {
            if (driver.FindElement(by).Displayed)
            {
                //jQuery is supported.
                if ((bool)((IJavaScriptExecutor)driver).ExecuteScript("return window.$ != undefined"))
                {
                    return (bool)((IJavaScriptExecutor)driver).ExecuteScript("return $.active == 0");
                }
                else
                {
                    return true;
                }
            }
            else
            {
                return false;
            }
        }
        catch (Exception)
        {
            return false;
        }
    }

you can do something like that:

where regexp_like(name, 'string$', 'i');

I think this wont be true for all the cases. Because css will download parallel but js cant. Consider for the same case,

Instead of having single css, take 2 or 3 css files and try it out these ways,

1) css..css..js 2) css..js..css 3) js..css..css

I'm sure css..css..js will give better result than all others.

I had a problem where I had to round up only and these answers didnt work for how I had to have my code run so I used a different method. The INT function rounds towards negative (4.2 goes to 4, -4.2 goes to -5) Therefore, I changed my function to negative, applied the INT function, then returned it to positive simply by multiplying it by -1 before and after

Count = -1 * (int(-1 * x))

The easiest solution is to use percentages. This isn't exactly the answer you were looking for since you asked for pixel-precision, but if you just need something to have a little padding between the right edge and the image, giving something a position of 99% usually works well enough.

Code:

/* aligns image to the vertical center and horizontal right of its container with a small amount of padding between the right edge */
div.middleleft {
  background: url("/images/source.jpg") 99% center no-repeat;
}

Thanks to Java 8 you don't need to do the steps below to pass a function to a method, that's what lambdas are for, see Oracle's Lambda Expression tutorial. The rest of this post describes what we used to have to do in the bad old days in order to implement this functionality.

Typically you declare your method as taking some interface with a single method, then you pass in an object that implements that interface. An example is in commons-collections, where you have interfaces for Closure, Transformer, and Predicate, and methods that you pass implementations of those into. Guava is the new improved commons-collections, you can find equivalent interfaces there.

So for instance, commons-collections has org.apache.commons.collections.CollectionUtils, which has lots of static methods that take objects passed in, to pick one at random, there's one called exists with this signature:

static boolean exists(java.util.Collection collection, Predicate predicate) 

It takes an object that implements the interface Predicate, which means it has to have a method on it that takes some Object and returns a boolean.

So I can call it like this:

CollectionUtils.exists(someCollection, new Predicate() {
    public boolean evaluate(Object object) { 
        return ("a".equals(object.toString());
    }
});

and it returns true or false depending on whether someCollection contains an object that the predicate returns true for.

Anyway, this is just an example, and commons-collections is outdated. I just forget the equivalent in Guava.

Works fine, except this message:

Implicit conversion from data type varchar to timestamp is not allowed. Use the CONVERT function to run this query

So yes, TIMESTAMP (RowVersion) is NOT a DATE :)

To be honest, I fidddled around quite some time myself to find a way to convert it to a date.

Best way is to convert it to INT and compare. That's what this type is meant to be.

If you want a date - just add a Datetime column and live happily ever after :)

Angular 2.x && Angular 4.x do not support this out of the box

You can use this two pipes to iterate either by key or by value.

Keys pipe:

import {Pipe, PipeTransform} from '@angular/core'

@Pipe({
  name: 'keys',
  pure: false
})
export class KeysPipe implements PipeTransform {
  transform(value: any, args: any[] = null): any {
    return Object.keys(value)
  }
}

Values pipe:

import {Pipe, PipeTransform} from '@angular/core'

@Pipe({
  name: 'values',
  pure: false
})
export class ValuesPipe implements PipeTransform {
  transform(value: any, args: any[] = null): any {
    return Object.keys(value).map(key => value[key])
  }
}

How to use:

let data = {key1: 'value1', key2: 'value2'}

<div *ngFor="let key of data | keys"></div>
<div *ngFor="let value of data | values"></div>

I achieved it by using method swizzling(Swift 4.2):

To create an UIViewController extension as follows

extension UIViewController {

    @objc private func swizzled_presentstyle(_ viewControllerToPresent: UIViewController, animated: Bool, completion: (() -> Void)?) {

        if #available(iOS 13.0, *) {
            if viewControllerToPresent.modalPresentationStyle == .automatic || viewControllerToPresent.modalPresentationStyle == .pageSheet {
                viewControllerToPresent.modalPresentationStyle = .fullScreen
            }
        }

        self.swizzled_presentstyle(viewControllerToPresent, animated: animated, completion: completion)
    }

     static func setPresentationStyle_fullScreen() {

        let instance: UIViewController = UIViewController()
        let aClass: AnyClass! = object_getClass(instance)

        let originalSelector = #selector(UIViewController.present(_:animated:completion:))
        let swizzledSelector = #selector(UIViewController.swizzled_presentstyle(_:animated:completion:))

        let originalMethod = class_getInstanceMethod(aClass, originalSelector)
        let swizzledMethod = class_getInstanceMethod(aClass, swizzledSelector)
        if let originalMethod = originalMethod, let swizzledMethod = swizzledMethod {
        method_exchangeImplementations(originalMethod, swizzledMethod)
        }
    }
}

and in AppDelegate, in application:didFinishLaunchingWithOptions: invoke the swizzling code by calling:

UIViewController.setPresentationStyle_fullScreen()

The ul.nav li is more restrictive and so takes precedence, try this:

ul.nav li.selected {  
  background-color:red; 
}

I understand this issue is resolved but I happened to solve this same problem on my own.

The cause of

Forbidden You don't have permission to access / on this server

is actually the default configuration for an apache directory in httpd.conf.

#
# Each directory to which Apache has access can be configured with respect
# to which services and features are allowed and/or disabled in that
# directory (and its subdirectories). 
#
# First, we configure the "default" to be a very restrictive set of 
# features.  
#
<Directory "/">
    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    Deny from all          # the cause of permission denied
</Directory>

Simply changing Deny from all to Allow from all should solve the permission problem.

Alternatively, a better approach would be to specify individual directory permissions on virtualhost configuration.

<VirtualHost *:80>
    ....

    # Set access permission
    <Directory "/path/to/docroot">
        Allow from all
    </Directory>

    ....
</VirtualHost>

As of Apache-2.4, however, access control is done using the new module mod_authz_host (Upgrading to 2.4 from 2.2). Consequently, the new Require directive should be used.

<VirtualHost *:80>
    ....

    # Set access permission
    <Directory "/path/to/docroot">
        Require all granted
    </Directory>

    ....
</VirtualHost>

Well, once you have your font, you can invoke deriveFont. For example,

helvetica = helvetica.deriveFont(Font.BOLD, 12f);

Changes the font's style to bold and its size to 12 points.

Hi first of all i would like you to use 'Synaptic Package Manager'. You just need to goto the ubuntu software center and search for synaptic package manager.. The beauty of this is that all the packages you need are easily available here. Second it will automatically configures all your paths. Now install this then search for opencv packages over there if you found the package with the green box then its installed but else the package is not in the right place so you need to reinstall it but from package manager this time. If installed then you can do this only, you just need to fill the OpenCV_DIR variable with the path of opencv (containing the OpenCVConfig.cmake file)

    export OpenCV_DIR=<path_of_opencv>

Take a look also at etcd and Consul.

Your quotes are in the wrong spot. Here's a simple example:

<div style={{backgroundColor: "#FF0000"}}>red</div>

Not all programs do the same thing or run on the same hardware.

This is usually the answer why various language features exist. Arrays are a core computer science concept. Replacing arrays with lists/matrices/vectors/whatever advanced data structure would severely impact performance, and be downright impracticable in a number of systems. There are any number of cases where using one of these "advanced" data collection objects should be used because of the program in question.

In business programming (which most of us do), we can target hardware that is relatively powerful. Using a List in C# or Vector in Java is the right choice to make in these situations because these structures allow the developer to accomplish the goals faster, which in turn allows this type of software to be more featured.

When writing embedded software or an operating system an array may often be the better choice. While an array offers less functionality, it takes up less RAM, and the compiler can optimize code more efficiently for look-ups into arrays.

I am sure I am leaving out a number of the benefits for these cases, but I hope you get the point.

Oh I found it in the PHP manual.

foreach ($array as $key => $value){
    statement
}

The current element's key will be assigned to the variable $key on each loop.

Text inside an ifdef/endif or ifndef/endif pair will be left in or removed by the pre-processor depending on the condition. ifdef means "if the following is defined" while ifndef means "if the following is not defined".

So:

#define one 0
#ifdef one
    printf("one is defined ");
#endif
#ifndef one
    printf("one is not defined ");
#endif

is equivalent to:

printf("one is defined ");

since one is defined so the ifdef is true and the ifndef is false. It doesn't matter what it's defined as. A similar (better in my opinion) piece of code to that would be:

#define one 0
#ifdef one
    printf("one is defined ");
#else
    printf("one is not defined ");
#endif

since that specifies the intent more clearly in this particular situation.

In your particular case, the text after the ifdef is not removed since one is defined. The text after the ifndef is removed for the same reason. There will need to be two closing endif lines at some point and the first will cause lines to start being included again, as follows:

     #define one 0
+--- #ifdef one
|    printf("one is defined ");     // Everything in here is included.
| +- #ifndef one
| |  printf("one is not defined "); // Everything in here is excluded.
| |  :
| +- #endif
|    :                              // Everything in here is included again.
+--- #endif

Something to keep in mind is that this error isn't only due to self signed certs. The new Entrust CA certs fail with the same error, and the right thing to do is to update the server with the appropriate root certs, not to disable this important security feature.

Divider color:

It is a hack a bit, but it works great for me and it works without any external library (at least on Android 4.4).

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle(R.string.dialog)
       .setIcon(R.drawable.ic)
       .setMessage(R.string.dialog_msg);
//The tricky part
Dialog d = builder.show();
int dividerId = d.getContext().getResources().getIdentifier("android:id/titleDivider", null, null);
View divider = d.findViewById(dividerId);
divider.setBackgroundColor(getResources().getColor(R.color.my_color));

You can find more dialog's ids in alert_dialog.xml file. Eg. android:id/alertTitle for changing title color...

UPDATE: Title color

Hack for changing title color:

int textViewId = d.getContext().getResources().getIdentifier("android:id/alertTitle", null, null);
TextView tv = (TextView) d.findViewById(textViewId);
tv.setTextColor(getResources().getColor(R.color.my_color));

If you have onRequestPermissionsResult in both activity and fragment, make sure to call super.onRequestPermissionsResult in activity. It is not required in fragment, but it is in activity.

//Find duplicates 

$arr = array( 
    'unique', 
    'duplicate', 
    'distinct', 
    'justone', 
    'three3', 
    'duplicate', 
    'three3', 
    'three3', 
    'onlyone' 
);

$unique = array_unique($arr); 
$dupes = array_diff_key( $arr, $unique ); 
    // array( 5=>'duplicate', 6=>'three3' 7=>'three3' )

// count duplicates

array_count_values($dupes); // array( 'duplicate'=>1, 'three3'=>2 )

I set width as max-content and it worked for me.

width: max-content;

You need to wait for the emulator to full start - takes a few minutes. Once it is fully started (UI on the emulator will change), it should work.

You will need to restart the app after the emulator is running and choose the running emulator when prompted.

bool IsPalindrome(const char* psz)
{
    int i = 0;
    int j;

    if ((psz == NULL) || (psz[0] == '\0'))
    {
        return false;
    }

    j = strlen(psz) - 1;
    while (i < j)
    {
        if (psz[i] != psz[j])
        {
            return false;
        }
        i++;
        j--;
    }
    return true;

}

// STL string version:

bool IsPalindrome(const string& str)
{
    if (str.empty())
        return false;

    int i = 0;                // first characters
    int j = str.length() - 1; // last character

    while (i < j)
    {
        if (str[i] != str[j])
        {
            return false;
        }
        i++;
        j--;
    }
    return true;
}

I would first concatenate the arrays, then I would return only the unique value.

You have to create your own function to return unique values. Since it is a useful function, you might as well add it in as a functionality of the Array.

In your case with arrays array1 and array2 it would look like this:

1. array1.concat(array2) - concatenate the two arrays
2. array1.concat(array2).unique() - return only the unique values. Here unique() is a method you added to the prototype for Array.

The whole thing would look like this:

Array.prototype.unique = function () {_x000D_
    var r = new Array();_x000D_
    o: for(var i = 0, n = this.length; i < n; i++)_x000D_
    {_x000D_
        for(var x = 0, y = r.length; x < y; x++)_x000D_
        {_x000D_
            if(r[x]==this[i])_x000D_
            {_x000D_
                continue o;_x000D_
            }_x000D_
        }_x000D_
        r[r.length] = this[i];_x000D_
    }_x000D_
    return r;_x000D_
}_x000D_
var array1 = [34,35,45,48,49];_x000D_
var array2 = [34,35,45,48,49,55];_x000D_
_x000D_
// concatenate the arrays then return only the unique values_x000D_
console.log(array1.concat(array2).unique());

If you want your script to return values, just do return [1,2,3] from a function wrapping your code but then you'd have to import your script from another script to even have any use for that information:

Return values (from a wrapping-function)

(again, this would have to be run by a separate Python script and be imported in order to even do any good):

import ...
def main():
    # calculate stuff
    return [1,2,3]

Exit codes as indicators

(This is generally just good for when you want to indicate to a governor what went wrong or simply the number of bugs/rows counted or w/e. Normally 0 is a good exit and >=1 is a bad exit but you could inter-prate them in any way you want to get data out of it)

import sys
# calculate and stuff
sys.exit(100)

And exit with a specific exit code depending on what you want that to tell your governor. I used exit codes when running script by a scheduling and monitoring environment to indicate what has happened.

(os._exit(100) also works, and is a bit more forceful)

Stdout as your relay

If not you'd have to use stdout to communicate with the outside world (like you've described). But that's generally a bad idea unless it's a parser executing your script and can catch whatever it is you're reporting to.

import sys
# calculate stuff
sys.stdout.write('Bugs: 5|Other: 10\n')
sys.stdout.flush()
sys.exit(0)

Are you running your script in a controlled scheduling environment then exit codes are the best way to go.

Files as conveyors

There's also the option to simply write information to a file, and store the result there.

# calculate
with open('finish.txt', 'wb') as fh:
    fh.write(str(5)+'\n')

And pick up the value/result from there. You could even do it in a CSV format for others to read simplistically.

Sockets as conveyors

If none of the above work, you can also use network sockets locally *(unix sockets is a great way on nix systems). These are a bit more intricate and deserve their own post/answer. But editing to add it here as it's a good option to communicate between processes. Especially if they should run multiple tasks and return values.

There is no hex code for transparency. For CSS, you can use either transparent or rgba(0, 0, 0, 0).

ZeroMQ is really with zero queues! It is a really mistake! It does not hav queues, topics, persistence, nothing! It is only a middleware for sockets API. If it is what you are looking cool! otherwise forget it! it is not like activeMQ or rabbitmq.

     would be a work around if you're only after the spacing.

In the Table Designer on SQL Server Management Studio you can set the where the auto increment will start. Right-click on the table in Object Explorer and choose Design, then go to the Column Properties for the relevant column:

Here the autoincrement will start at 760

It is in the dist folder inside of the project, but only if "Compress WAR File" in the project settings dialog ( build / packaging) ist checked. Before I checked this checkbox there was no dist folder.

You can access this folder using the DDMS for your Emulator. you can't access this location on a real device unless you have a rooted device.

You can view Table structure and Data in Eclipse. Here are the steps

1. Install SqliteManagerPlugin for Eclipse. Jump to step 5 if you already have it.
2. Download the *.jar file from here
3. Put the *.jar file into the folder eclipse/dropins/
4. Restart eclipse
5. In the top right of eclipse, click the DDMS icon
6. Select the proper emulator in the left panel
7. In the File Explorer tab on the main panel, go to /data/data/[YOUR.APP.NAMESPACE]/databases
8. Underneath the DDMS icon, there should be a new blue icon of a Database light up when you select your database. Click it and you will see a Questoid Sqlite Manager tab open up to view your data.

*Note: If the database doesn't light up, it may be because your database doesn't have a *.db file extension. Be sure your database is called [DATABASE_NAME].db

*Note: if you want to use a DB without .db-Extension:

1. Download this Questoid SqLiteBrowser: http://www.java2s.com/Code/JarDownload/com.questoid/com.questoid.sqlitebrowser_1.2.0.jar.zip

2. Unzip and put it into eclipse/dropins (not Plugins)

I'll rename the function take_closest to conform with PEP8 naming conventions.

If you mean quick-to-execute as opposed to quick-to-write, min should not be your weapon of choice, except in one very narrow use case. The min solution needs to examine every number in the list and do a calculation for each number. Using bisect.bisect_left instead is almost always faster.

The "almost" comes from the fact that bisect_left requires the list to be sorted to work. Hopefully, your use case is such that you can sort the list once and then leave it alone. Even if not, as long as you don't need to sort before every time you call take_closest, the bisect module will likely come out on top. If you're in doubt, try both and look at the real-world difference.

from bisect import bisect_left

def take_closest(myList, myNumber):
    """
    Assumes myList is sorted. Returns closest value to myNumber.

    If two numbers are equally close, return the smallest number.
    """
    pos = bisect_left(myList, myNumber)
    if pos == 0:
        return myList[0]
    if pos == len(myList):
        return myList[-1]
    before = myList[pos - 1]
    after = myList[pos]
    if after - myNumber < myNumber - before:
       return after
    else:
       return before

Bisect works by repeatedly halving a list and finding out which half myNumber has to be in by looking at the middle value. This means it has a running time of O(log n) as opposed to the O(n) running time of the highest voted answer. If we compare the two methods and supply both with a sorted myList, these are the results:

$ python -m timeit -s "
from closest import take_closest
from random import randint
a = range(-1000, 1000, 10)" "take_closest(a, randint(-1100, 1100))"

100000 loops, best of 3: 2.22 usec per loop

$ python -m timeit -s "
from closest import with_min
from random import randint
a = range(-1000, 1000, 10)" "with_min(a, randint(-1100, 1100))"

10000 loops, best of 3: 43.9 usec per loop

So in this particular test, bisect is almost 20 times faster. For longer lists, the difference will be greater.

What if we level the playing field by removing the precondition that myList must be sorted? Let's say we sort a copy of the list every time take_closest is called, while leaving the min solution unaltered. Using the 200-item list in the above test, the bisect solution is still the fastest, though only by about 30%.

This is a strange result, considering that the sorting step is O(n log(n))! The only reason min is still losing is that the sorting is done in highly optimalized c code, while min has to plod along calling a lambda function for every item. As myList grows in size, the min solution will eventually be faster. Note that we had to stack everything in its favour for the min solution to win.

You missed the each= argument to rep():

R> n <- 3
R> rep(1:5, each=n)
 [1] 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5
R> 

so your example can be done with a simple

R> rep(1:8, each=20)

For Visual Studio 2017, 2019. I got this error and able to fix it just by enable the Live Share extension from extensions.

see the VS community page for detail.

Use the ArrayList copy constructor, then sort that.

List oldList;
List newList = new ArrayList(oldList);
Collections.sort(newList);

After making the copy, any changes to newList do not affect oldList.

Note however that only the references are copied, so the two lists share the same objects, so changes made to elements of one list affect the elements of the other.

Alternatively, you can use Guava's Resources object:

URL url = new URL("http://www.puzzlers.org/pub/wordlists/pocket.txt");
List<String> lines = Resources.readLines(url, Charsets.UTF_8);
lines.forEach(System.out::println);

I use Nodemon version 1.88.3 in my Node.js project. To install Nodemon, see in https://www.npmjs.com/package/nodemon.

Check your package.json, see if "scripts" has changed like this:

  "scripts": {
    "dev": "nodemon server.js"
  },

server.js is my file name, you can use another name for this file like app.js.

After that, run this on your terminal: npm run dev

I did a little experiment to see which of these methods

• string.startswith('hello')
• string.rfind('hello') == 0
• string.rpartition('hello')[0] == ''
• string.rindex('hello') == 0

are most efficient to return whether a certain string begins with another string.

Here is the result of one of the many test runs I've made, where each list is ordered to show the least time it took (in seconds) to parse 5 million of each of the above expressions during each iteration of the while loop I used:

['startswith: 1.37', 'rpartition: 1.38', 'rfind: 1.62', 'rindex: 1.62']

['startswith: 1.28', 'rpartition: 1.43', 'rfind: 1.59', 'rindex: 1.66']

I believe that it is pretty obvious from the start that the startswith method would come out the most efficient, as returning whether a string begins with the specified string is its main purpose.

What surprises me is that the seemingly impractical string.rpartition('hello')[0] == '' method always finds a way to be listed first, before the string.startswith('hello') method, every now and then. The results show that using str.partition to determine if a string starts with another string is more efficient then using both rfind and rindex.

Another thing I've noticed is that string.rindex('hello') == 0 and string.rindex('hello') == 0 have a good battle going on, each rising from fourth to third place, and dropping from third to fourth place, which makes sense, as their main purposes are the same.

Here is the code:

from time import perf_counter

string = 'hello world'
places = dict()

while True:
    start = perf_counter()
    for _ in range(5000000):
        string.startswith('hello')
    end = perf_counter()
    places['startswith'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rfind('hello') == 0
    end = perf_counter()
    places['rfind'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rpartition('hello')[0] == ''
    end = perf_counter()
    places['rpartition'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rindex('hello') == 0
    end = perf_counter()
    places['rindex'] = round(end - start, 2)
    
    print([f'{b}: {str(a).ljust(4, "4")}' for a, b in sorted(i[::-1] for i in places.items())])

    public void ChargingArraySelect()
    {
        int loop = 0;
        int registros = 0;

        OdbcConnection conn = WebApiConfig.conn();
        OdbcCommand query = conn.CreateCommand();

        query.CommandText = "select dataA, DataB, dataC, DataD FROM table  where dataA = 'xpto'";

        try
        {
            conn.Open();
            OdbcDataReader dr = query.ExecuteReader();

            //take the number the registers, to use into next step
            registros = dr.RecordsAffected;

            //calls an array to be populated
            Global.arrayTest = new string[registros, 4];

            while (dr.Read())

                    Global.arrayTest[i, 1] = Convert.ToString(dr["dataB"]);
                    Global.arrayTest[i, 2] = Convert.ToString(dr["dataC"]);
                    Global.arrayTest[i, 3] = Convert.ToString(dr["dataD"]);
                }
                loop++;
            }
        }
    }


    //Declaration the Globais Array in Global Classs
    private static string[] uso_internoArray1;
    public static string[] arrayTest

Modern browsers support the "viewport height" unit. This will expand the div to the available viewport height. I find it more reliable than any other approach.

#some_div {
    height: 100vh;
    background: black;
}

YES - solution is to save workbook in to XML file (eg. 'XML Spreadsheet 2003') and edit this file as text in notepad! use "SEARCH" function of notepad to find query text and change your data to "?".

save and open in excel, try refresh data and excel will be monit about parameters.

delete[] monsters is definitely wrong. My heap debugger shows the following output:

allocated non-array memory at 0x3e38f0 (20 bytes)
allocated non-array memory at 0x3e3920 (20 bytes)
allocated non-array memory at 0x3e3950 (20 bytes)
allocated non-array memory at 0x3e3980 (20 bytes)
allocated non-array memory at 0x3e39b0 (20 bytes)
allocated non-array memory at 0x3e39e0 (20 bytes)
releasing     array memory at 0x22ff38

As you can see, you are trying to release with the wrong form of delete (non-array vs. array), and the pointer 0x22ff38 has never been returned by a call to new. The second version shows the correct output:

[allocations omitted for brevity]
releasing non-array memory at 0x3e38f0
releasing non-array memory at 0x3e3920
releasing non-array memory at 0x3e3950
releasing non-array memory at 0x3e3980
releasing non-array memory at 0x3e39b0
releasing non-array memory at 0x3e39e0

Anyway, I prefer a design where manually implementing the destructor is not necessary to begin with.

#include <array>
#include <memory>

class Foo
{
    std::array<std::shared_ptr<Monster>, 6> monsters;

    Foo()
    {
        for (int i = 0; i < 6; ++i)
        {
            monsters[i].reset(new Monster());
        }
    }

    virtual ~Foo()
    {
        // nothing to do manually
    }
};

Possible Duplicate Question

<@include> - The directive tag instructs the JSP compiler to merge contents of the included file into the JSP before creating the generated servlet code. It is the equivalent to cutting and pasting the text from your include page right into your JSP.

• Only one servlet is executed at run time.
• Scriptlet variables declared in the parent page can be accessed in the included page (remember, they are the same page).
• The included page does not need to able to be compiled as a standalone JSP. It can be a code fragment or plain text. The included page will never be compiled as a standalone. The included page can also have any extension, though .jspf has become a conventionally used extension.
• One drawback on older containers is that changes to the include pages may not take effect until the parent page is updated. Recent versions of Tomcat will check the include pages for updates and force a recompile of the parent if they're updated.
• A further drawback is that since the code is inlined directly into the service method of the generated servlet, the method can grow very large. If it exceeds 64 KB, your JSP compilation will likely fail.

<jsp:include> - The JSP Action tag on the other hand instructs the container to pause the execution of this page, go run the included page, and merge the output from that page into the output from this page.

• Each included page is executed as a separate servlet at run time.
• Pages can conditionally be included at run time. This is often useful for templating frameworks that build pages out of includes. The parent page can determine which page, if any, to include according to some run-time condition.
• The values of scriptlet variables need to be explicitly passed to the include page.
• The included page must be able to be run on its own.
• You are less likely to run into compilation errors due to the maximum method size being exceeded in the generated servlet class.

Depending on your needs, you may either use <@include> or <jsp:include>

The easiest solution is to use tutum/mysql

Step1

docker pull tutum/mysql:5.5

Step2

docker run -d -p 3306:3306 -v /tmp:/tmp  -e STARTUP_SQL="/tmp/to_be_imported.mysql" tutum/mysql:5.5

Step3

Get above CONTAINER_ID and then execute command docker logs to see the generated password information.

docker logs #<CONTAINER_ID>

The Comparable example given by several people here is wrong, since Enum already implements that. You can't even override it.

A better example is having an interface that defines, let's say, a data type. You can have an enum to implement the simple types, and have normal classes to implement complicated types:

interface DataType {
  // methods here
}

enum SimpleDataType implements DataType {
  INTEGER, STRING;

  // implement methods
}

class IdentifierDataType implements DataType {
  // implement interface and maybe add more specific methods
}

The second function should have:

var value = document.getElementById(id).value;

Then they are basically the same function.

i would recommend Modern UI for WPF .

It has a very active maintainer it is awesome and free!

I'm currently porting some projects to MUI, first (and meanwhile second) impression is just wow!

To see MUI in action you could download XAML Spy which is based on MUI.

EDIT: Using Modern UI for WPF a few months and i'm loving it!

Use stat(), if it is cross-platform enough for your needs. It is not C++ standard though, but POSIX.

On MS Windows there is _stat, _stat64, _stati64, _wstat, _wstat64, _wstati64.

Use: $("<p>Test</p>").prependTo(".inner"); Check out the .prepend documentation on jquery.com

This one-liner should work:

npm start --prefix path/to/your/app

In Swift 3.0

let screenSize = UIScreen.main.bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height

In older swift: Do something like this:

let screenSize: CGRect = UIScreen.mainScreen().bounds

then you can access the width and height like this:

let screenWidth = screenSize.width
let screenHeight = screenSize.height

if you want 75% of your screen's width you can go:

let screenWidth = screenSize.width * 0.75

Swift 4.0

// Screen width.
public var screenWidth: CGFloat {
    return UIScreen.main.bounds.width
}

// Screen height.
public var screenHeight: CGFloat {
    return UIScreen.main.bounds.height
}

In Swift 5.0

let screenSize: CGRect = UIScreen.main.bounds

In the "root" __init__.py you can also do a

import sys
sys.path.insert(1, '.')

which should make both modules importable.

I would go with

i = np.min(np.where(V >= x))

where V is vector (1d array), x is the value and i is the resulting index.

You can also add prompt option like this.

<%= f.select(:object_field, ['Item 1', 'Item 2'], {include_blank: "Select something"}, { :class => 'my_style_class' }) %>

I solved this issue by doing the following:

1. Add default_authentication_plugin = mysql_native_password to the
   [mysqld] section of my.cnf
2. Enter mysql and create a new user by doing something like CREATE USER 'root'@'localhost' IDENTIFIED BY 'password';
3. Grant privileges as necessary. E.g. GRANT ALL PRIVILEGES ON * . * TO 'root'@'localhost'; and then FLUSH PRIVILEGES;
4. Login into phpmyadmin with new user

You can get all keys in the Request.Form and then compare and get your desired values.

Your method body will look like this: -

List<int> listValues = new List<int>();
foreach (string key in Request.Form.AllKeys)
{
    if (key.StartsWith("List"))
    {
        listValues.Add(Convert.ToInt32(Request.Form[key]));
    }
}

If you need the construct for a quick example to play with, use the : operator.

But if you are creating a vector/range of numbers dynamically, then use seq() instead.

Let's say you are creating the vector/range of numbers from a to b with a:b, and you expect it to be an increasing series. Then, if b is evaluated to be less than a, you will get a decreasing sequence but you will never be notified about it, and your program will continue to execute with the wrong kind of input.

In this case, if you use seq(), you can set the sign of the by argument to match the direction of your sequence, and an error will be raised if they do not match. For example,

seq(a, b, -1)

will raise an error for a=2, b=6, because the coder expected a decreasing sequence.

I was in a situation where Linq binding was not available and had to expand lambda explicitly. It resulted in a simple function:

public static T KeyByValue<T, W>(this Dictionary<T, W> dict, W val)
{
    T key = default;
    foreach (KeyValuePair<T, W> pair in dict)
    {
        if (EqualityComparer<W>.Default.Equals(pair.Value, val))
        {
            key = pair.Key;
            break;
        }
    }
    return key;
}

Call it like follows:

public static void Main()
{
    Dictionary<string, string> dict = new Dictionary<string, string>()
    {
        {"1", "one"},
        {"2", "two"},
        {"3", "three"}
    };

    string key = KeyByValue(dict, "two");       
    Console.WriteLine("Key: " + key);
}

Works on .NET 2.0 and in other limited environments.

I use

 android:screenOrientation="nosensor"

It is helpful if you do not want to support up side down portrait mode.

..and to detect a change in resolution to handle it (once you're using Docking and Anchoring like SwDevMan81 suggested) use the SystemEvents.DisplaySettingsChanged event in Microsoft.Win32.

If I understand you right, you can do this:

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

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

In your last block you have a comma after 'lang', followed immediately with a function. This is not valid json.

EDIT

It appears that the readme was incorrect. I had to to pass an array with the string 'twitter'.

var converter = new Showdown.converter({extensions: ['twitter']}); converter.makeHtml('whatever @meandave2020'); // output "<p>whatever <a href="http://twitter.com/meandave2020">@meandave2020</a></p>"

Datetime formatting is performed by the org.joda.time.format.DateTimeFormatter class. Three classes provide factory methods to create formatters, and this is one. The others are ISODateTimeFormat and DateTimeFormatterBuilder.

DateTimeFormatter format = DateTimeFormat.forPattern("yyyy-MMM-dd");
LocalDate lDate = new LocalDate().parse("2005-nov-12",format);

final org.joda.time.LocalDate class is an immutable datetime class representing a date without a time zone. LocalDate is thread-safe and immutable, provided that the Chronology is as well. All standard Chronology classes supplied are thread-safe and immutable.

For macOS Sierra, to build wget 1.18 from source with Xcode 8.2.

1. Install Xcode

2. Build OpenSSL

   Since Xcode doesn't come with OpenSSL lib, you need build by yourself. I found this: https://github.com/sqlcipher/openssl-xcode, follow instruction and build OpenSSL lib. Then, prepare your OpenSSL directory with "include" and "lib/libcrypto.a", "lib/libssl.a" in it.

   Let's say it is: "/Users/xxx/openssl-xcode/openssl", so there should be "/Users/xxx/openssl-xcode/openssl/include" for OpenSSL include and "/Users/xxx/openssl-xcode/openssl/lib" for "libcrypto.a" and "libssl.a".

3. Build wget

   Go to wget directory, configure:

   ./configure --with-ssl=openssl --with-libssl-prefix=/Users/xxx/openssl-xcode/openssl
   

   wget should configure and found OpenSSL, then make:

   make
   

   wget made out. Install wget:

   make install
   

   Or just copy wget to where you want.

4. Configure cert

   You may find wget cannot verify any https connection, because there is no CA certs for the OpenSSL you built. You need to run:

   New way:

   If you machine doesn't have "/usr/local/ssl/" dir, first make it.

   ln -s /etc/ssl/cert.pem /usr/local/ssl/cert.pem
   

   Old way:

   security find-certificate -a -p /Library/Keychains/System.keychain > cert.pem
   security find-certificate -a -p /System/Library/Keychains/SystemRootCertificates.keychain >> cert.pem
   

   Then put cert.pem to: "/usr/local/ssl/cert.pem"

   DONE: It should be all right now.

For inversion from 0 to 1 and back you can use this library InvertImages, which provides support for IE 10. I also tested with IE 11 and it should work.

Here is how I got it going specifically for the admob sdk jar file:

1. Drag your jar file into the libs folder.
2. Right click on the jar file and select Add Library now the jar file is a library lets add it to the compile path
3. Open the build.gradle file (note there are two build.gradle files at least, don't use the root one use the one in your project scope).

4. Find the dependencies section (for me i was trying to the admob -GoogleAdMobAdsSdk jar file) e.g.

   dependencies {
      compile files('libs/android-support-v4.jar','libs/GoogleAdMobAdsSdk-6.3.1.jar')
   }
   

5. Last go into settings.gradle and ensure it looks something like this:

   include ':yourproject', ':yourproject:libs:GoogleAdMobAdsSdk-6.3.1'
   

6. Finally, Go to Build -> Rebuild Project

From SQL Server 2008 SSMS (SQL Server Management Studio), simply:

1. Connect to your database instance (for example, "localhost\sqlexpress")

2. Either:

   • a) Select the database you want to restore to; or, alternatively
   • b) Just create a new, empty database to restore to.

3. Right-click, Tasks, Restore, Database

4. Device, [...], Add, Browse to your .bak file
5. Select the backup.
   Choose "overwrite=Y" under options.
   Restore the database
6. It should say "100% complete", and your database should be on-line.

PS: Again, I emphasize: you can easily do this on a "scratch database" - you do not need to overwrite your current database. But you do need to RESTORE.

PPS: You can also accomplish the same thing with T-SQL commands, if you wished to script it.

It depends if you consider if a subclass of a given class is equals to its parent.

class LastName
{
(...)
}


class FamilyName
extends LastName
{
(..)
}

here I would use 'instanceof', because I want a LastName to be compared to FamilyName

class Organism
{
}

class Gorilla extends Organism
{
}

here I would use 'getClass', because the class already says that the two instances are not equivalent.

Yes, and basically you can also use inline style:

<span style="font-size: 15px" class="glyphicon glyphicon-cog"></span>

 if ($('input:checkbox').filter(':checked').length < 1){
        alert("Check at least one!");
 return false;
 }

another ways:

1) include the css code(file) of Yahoo CSS reset and then put everything inside this DIV:

<div class="yui3-cssreset">
    <!-- Anything here would be reset-->
</div>

2) or use

• https://cssreset.com/scripts/vanilla-css-un-reset/
• https://cssreset.com/scripts/html5-doctor-css-reset-stylesheet/
• https://cssreset.com/scripts/eric-meyer-reset-css/
• https://cssreset.com/scripts/tripoli-css-reset-david-hellsing/

 var xxxx : { [key:number]: MyType };

I added a HorizontalAlignment="Center" (The default is "Strech") and it solved my problem because it made the datagrid only as wide as needed. (Removed the datagrid's Width setting if you have one.)

How about this :

            // Checks to see if the value passed is valid. 
            if (!TypeDescriptor.GetConverter(typeof(T)).IsValid(value))
            {
                throw new ArgumentException();
            }

You can send the parameters in the URL of the POST request itself.

Example URL:

localhost:8080/abc/getDetails?paramter1=value1&parameter2=value2

Once you copy such type of URL in Firefox REST client make a POST call to the server you want

<script>
    window.location.hash = "no-back-button";

    // Again because Google Chrome doesn't insert
    // the first hash into the history
    window.location.hash = "Again-No-back-button"; 

    window.onhashchange = function(){
        window.location.hash = "no-back-button";

You can get a list by looking into the document.cookie variable. Clearing them all is just a matter of looping over all of them and clearing them one by one.

SELECT COUNT(*) FROM table1 WHERE id = 1;

if COUNT(*) = 0

INSERT INTO table1(col1, col2, cole) VALUES(var1,var2,var3);

else if COUNT(*) > 0

UPDATE table1 SET col1 = var4, col2 = var5, col3 = var6 WHERE id = 1;

I use a customized version of DX Auth. I found it simple to use, extremely easy to modify and it has a user guide (with great examples) that is very similar to Code Igniter's.

Declare @month as char(2)
Declare @date as char(2)
Declare @year as char(4)
declare @time as char(8)
declare @customdate as varchar(20)

set @month = MONTH(GetDate());
set @date = Day(GetDate());
set @year = year(GetDate());

set @customdate= @month+'/'+@date+'/'+@year+' '+ CONVERT(varchar(8), GETDATE(),108);
print(@customdate)

I have answered this question here..Covariant virtual functions return type problem

See if it helps for some one.

You can set the year range using this option per documentation here http://api.jqueryui.com/datepicker/#option-yearRange

yearRange: '1950:2013', // specifying a hard coded year range

or this way

yearRange: "-100:+0", // last hundred years

From the Docs

Default: "c-10:c+10"

The range of years displayed in the year drop-down: either relative to today's year ("-nn:+nn"), relative to the currently selected year ("c-nn:c+nn"), absolute ("nnnn:nnnn"), or combinations of these formats ("nnnn:-nn"). Note that this option only affects what appears in the drop-down, to restrict which dates may be selected use the minDate and/or maxDate options.

I know that this post is quite old, but for reference I fixed this issue by updating the version of datepicker

It is worth trying that too to avoid hours of debugging.

const is for compile-time constants. You could just make it static readonly, but that would only apply to the METRICS variable itself (which should typically be Metrics instead, by .NET naming conventions). It wouldn't make the list immutable - so someone could call METRICS.Add("shouldn't be here");

You may want to use a ReadOnlyCollection<T> to wrap it. For example:

public static readonly IList<String> Metrics = new ReadOnlyCollection<string>
    (new List<String> { 
         SourceFile.LoC, SourceFile.McCabe, SourceFile.NoM,
         SourceFile.NoA, SourceFile.FanOut, SourceFile.FanIn, 
         SourceFile.Par, SourceFile.Ndc, SourceFile.Calls });

ReadOnlyCollection<T> just wraps a potentially-mutable collection, but as nothing else will have access to the List<T> afterwards, you can regard the overall collection as immutable.

(The capitalization here is mostly guesswork - using fuller names would make them clearer, IMO.)

Whether you declare it as IList<string>, IEnumerable<string>, ReadOnlyCollection<string> or something else is up to you... if you expect that it should only be treated as a sequence, then IEnumerable<string> would probably be most appropriate. If the order matters and you want people to be able to access it by index, IList<T> may be appropriate. If you want to make the immutability apparent, declaring it as ReadOnlyCollection<T> could be handy - but inflexible.

Microsoft has also implemented the operators '<' and '>'. So you use these to compare two dates.

if (date1 < DateTime.Now)
   Console.WriteLine("Less than the current time!");

for all views (you need dba privileges for this query)

select view_name from dba_views

for all accessible views (accessible by logged user)

select view_name from all_views

for views owned by logged user

select view_name from user_views

SELECT CITY,LENGTH(CITY) FROM STATION GROUP BY CITY ORDER BY LENGTH(CITY) ASC LIMIT 1;
SELECT CITY,LENGTH(CITY) FROM STATION GROUP BY CITY ORDER BY LENGTH(CITY) DESC LIMIT 1;

It depends why the something is on the same line in the first place.

clear in the case of floats, display: block in the case of inline content naturally flowing, nothing will defeat position: absolute as the previous element will be taken out of the normal flow by it.

A few years late, but I'd like to add that if you need to do this in one fell swoop (like I did) you can set the config settings during the clone command. Try this:

git clone -c core.longpaths=true <your.url.here>

To add to the answers above: if you want to stop Dyno using admin panel, the current solution on free tier:

1. Open App
2. In Overview tab, in "Dyno formation" section click on "Configure Dynos"
3. In the needed row of "Free Dynos" section, click on the pencil icon on the right
4. Click on the blue on/off control, and then click on "Confirm"

Hope this helps.

You have a scope problem. Define the struct before the function, not inside it.

Use defaultValue to preselect the values for Select.

<Select defaultValue={[{ value: category.published, label: 'Publish' }]} options={statusOptions} onChange={handleStatusChange} />

Although I almost always just use pandas for this, my current little tool is being packaged into an executable and including pandas is overkill. So I created a version of poida's solution that resulted in a list of named tuples. His code with this change would look like this:

from xlrd import open_workbook
from collections import namedtuple
from pprint import pprint

wb = open_workbook('sample.xls')

FORMAT = ['Arm_id', 'DSPName', 'PinCode']
OneRow = namedtuple('OneRow', ' '.join(FORMAT))
all_rows = []

for s in wb.sheets():
    headerRow = s.row(0)
    columnIndex = [x for y in FORMAT for x in range(len(headerRow)) if y == headerRow[x].value]

    for row in range(1,s.nrows):
        currentRow = s.row(row)
        currentRowValues = [currentRow[x].value for x in columnIndex]
        all_rows.append(OneRow(*currentRowValues))

pprint(all_rows)

Barebones C program to produce the above error:

    //peeking too deeply into p, that's a paddlin.

    cout << **p;    
    //error: invalid type argument of `unary *'
    //peeking too deeply into p, you better believe that's a paddlin.
}

Then the master says: "Now open the stone and remove the stone". The student said: "I can't open a stone".

The student was then enlightened.

NO, you can't do it other way than so.

I created an extension method for moving items in a list.

An index should not shift if we are moving an existing item since we are moving an item to an existing index position in the list.

The edge case that @Oliver refers to below (moving an item to the end of the list) would actually cause the tests to fail, but this is by design. To insert a new item at the end of the list we would just call List<T>.Add. list.Move(predicate, list.Count) should fail since this index position does not exist before the move.

In any case, I've created two additional extension methods, MoveToEnd and MoveToBeginning, the source of which can be found here.

    {
        Ensure.Argument.NotNull(list, "list");
        Ensure.Argument.NotNull(itemSelector, "itemSelector");
        Ensure.Argument.Is(newIndex >= 0, "New index must be greater than or equal to zero.");

        var currentIndex = list.FindIndex(itemSelector);
        Ensure.That<ArgumentException>(currentIndex >= 0, "No item was found that matches the specified selector.");

        // Copy the current item
        var item = list[currentIndex];

        // Remove the item
        list.RemoveAt(currentIndex);

        // Finally add the item at the new index
        list.Insert(newIndex, item);
    }

This answer is a complement to @Evert's on the legend position.

My first try on @Evert's solution failed due to overlaps of the legend and the subplot's title.

In fact, the overlaps are caused by fig.tight_layout(), which changes the subplots' layout without considering the figure legend. However, fig.tight_layout() is necessary.

In order to avoid the overlaps, we can tell fig.tight_layout() to leave spaces for the figure's legend by fig.tight_layout(rect=(0,0,1,0.9)).

Old question I know, but for the curious:

Believe it or not, this issue was solved ~2 decades ago with HTTP BASIC, which passes the value as base64 encoded username:password. (See http://en.wikipedia.org/wiki/Basic_access_authentication#Client_side)

You could do the same, so that the example above would become:

Authorization: FIRE-TOKEN MFBONUoxN0hCR1pIVDdKSjNYODI6ZnJKSVVOOERZcEtEdE9MQ3dvLy95bGxxRHpnPQ==

JSL 1.7

The Oracle documentation mentions:

• unchecked: Unchecked warnings are identified by the string "unchecked".
• deprecation: A Java compiler must produce a deprecation warning when a type, method, field, or constructor whose declaration is annotated with the annotation @Deprecated is used (i.e. overridden, invoked, or referenced by name), unless: [...] The use is within an entity that is annotated to suppress the warning with the annotation @SuppressWarnings("deprecation"); or

It then explains that implementations can add and document their own:

Compiler vendors should document the warning names they support in conjunction with this annotation type. Vendors are encouraged to cooperate to ensure that the same names work across multiple compilers.

There is a way to do this without JavaScript!

You can use an inline SVG image. You can use CSS on an SVG if it is inline. You have to remember that using this method means your SVG image will respond to its container size.

Try using the following solution...

HTML

<div>
  <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 360.96 358.98" >
      <text>SAVE $500</text>
  </svg>
</div>

CSS

div {
  width: 50%; /* Set your container width */
  height: 50%; /* Set your container height */

}

svg {
  width: 100%;
  height: auto;

}

text {
  transform: translate(40px, 202px);
  font-size: 62px;
  fill: #000;
}

Example: https://jsfiddle.net/k8L4xLLa/32/

SVG images also allow you to do cool stuff with shapes and junk. Check out this great use case for scalable text...

POD is the official way to do multi line comments in Perl,

• see Multi-line comments in perl code and
• Better ways to make multi-line comments in Perl for more detail.

From faq.perl.org[perlfaq7]

• How can I comment out a large block of Perl code?

The quick-and-dirty way to comment out more than one line of Perl is to surround those lines with Pod directives. You have to put these directives at the beginning of the line and somewhere where Perl expects a new statement (so not in the middle of statements like the # comments). You end the comment with =cut, ending the Pod section:

=pod

my $object = NotGonnaHappen->new();

ignored_sub();

$wont_be_assigned = 37;

=cut

The quick-and-dirty method only works well when you don't plan to leave the commented code in the source. If a Pod parser comes along, your multiline comment is going to show up in the Pod translation. A better way hides it from Pod parsers as well.

The =begin directive can mark a section for a particular purpose. If the Pod parser doesn't want to handle it, it just ignores it. Label the comments with comment. End the comment using =end with the same label. You still need the =cut to go back to Perl code from the Pod comment:

=begin comment

my $object = NotGonnaHappen->new();

ignored_sub();

$wont_be_assigned = 37;

=end comment

=cut

Operations on integers are exact. double is a floating point data type, and floating point operations are approximate whenever there's a fraction.

double also takes up twice as much space as int in many implementations (e.g. most 32-bit systems) .

Assuming we imported pandas as pd and df is our dataframe

pd.to_datetime(df['date'], unit='s')

works for me.

Let's not forget good old parameters. When starting your *.bat or *.cmd file you can add up to nine parameters after the command file name:

call myscript.bat \\path\to\my\file.ext type
call myscript.bat \\path\to\my\file.ext "Del /F"

Example script

The myscript.bat could be something like this:

@Echo Off
Echo The path of this scriptfile %~0
Echo The name of this scriptfile %~n0
Echo The extension of this scriptfile %~x0
Echo.
If "%~2"=="" (
   Echo Parameter missing, quitting.
   GoTo :EOF
)
If Not Exist "%~1" (
   Echo File does not exist, quitting.
   GoTo :EOF
)
Echo Going to %~2 this file: %~1
%~2 "%~1"
If %errorlevel%  NEQ 0 (
   Echo Failed to %~2 the %~1.
)
@Echo On

Example output

c:\>c:\bats\myscript.bat \\server\path\x.txt type
The path of this scriptfile c:\bats\myscript.bat
The name of this scriptfile myscript
The extension of this scriptfile .bat

Going to type this file: \\server\path\x.txt
This is the content of the file:

Some numbers: 1234567890

c:\>c:\bats\myscript.bat \\server\path\x.txt "del /f "
The path of this scriptfile c:\bats\myscript.bat

From the doc for path.resolve:

The resulting path is normalized and trailing slashes are removed unless the path is resolved to the root directory.

If you use the Oracle native data provider rather than the Microsoft driver then you can get at all field types

Dim cn As New Oracle.DataAccess.Client.OracleConnection
Dim cm As New Oracle.DataAccess.Client.OracleCommand
Dim dr As Oracle.DataAccess.Client.OracleDataReader

The connection string does not require a Provider value so you would use something like:

"Data Source=myOracle;UserID=Me;Password=secret"

Open the connection:

cn.ConnectionString = "Data Source=myOracle;UserID=Me;Password=secret"
cn.Open()

Attach the command and set the Sql statement

cm.Connection = cn
cm.CommandText = strCommand

Set the Fetch size. I use 4000 because it's as big as a varchar can be

cm.InitialLONGFetchSize = 4000

Start the reader and loop through the records/columns

dr = cm.ExecuteReader

Do while dr.read()
    strMyLongString = dr(i)
Loop

You can be more specific with the read, eg dr.GetOracleString(i) dr.GetOracleClob(i) etc. if you first identify the data type in the column. If you're reading a LONG datatype then the simple dr(i) or dr.GetOracleString(i) works fine. The key is to ensure that the InitialLONGFetchSize is big enough for the datatype. Note also that the native driver does not support CommandBehavior.SequentialAccess for the data reader but you don't need it and also, the LONG field does not even have to be the last field in the select statement.

Gathering the code in the answers, I wrote this function that seems running well on my FF 25.

function CCSStylesheetRuleStyle(stylesheet, selectorText, style, value){
  /* returns the value of the element style of the rule in the stylesheet
  *  If no value is given, reads the value
  *  If value is given, the value is changed and returned
  *  If '' (empty string) is given, erases the value.
  *  The browser will apply the default one
  *
  * string stylesheet: part of the .css name to be recognized, e.g. 'default'
  * string selectorText: css selector, e.g. '#myId', '.myClass', 'thead td'
  * string style: camelCase element style, e.g. 'fontSize'
  * string value optionnal : the new value
  */
  var CCSstyle = undefined, rules;
  for(var m in document.styleSheets){
    if(document.styleSheets[m].href.indexOf(stylesheet) != -1){
     rules = document.styleSheets[m][document.all ? 'rules' : 'cssRules'];
     for(var n in rules){
       if(rules[n].selectorText == selectorText){
         CCSstyle = rules[n].style;
         break;
       }
     }
     break;
    }
  }
  if(value == undefined)
    return CCSstyle[style]
  else
    return CCSstyle[style] = value
}

This is a way to put values in the css that will be used in JS even if not understood by the browser. e.g. maxHeight for a tbody in a scrolled table.

Call :

CCSStylesheetRuleStyle('default', "#mydiv", "height");

CCSStylesheetRuleStyle('default', "#mydiv", "color", "#EEE");

I tried everything on here and finally discovered that it was the setup in my web.config. I removed that section and it worked fine; I will go back and troubleshoot later as to why it was busted.

*Edit: I removed the statusCode="503" because of an issue with the App_Offline.htm file and the way in which the errors were configured. I've removed the line below (it isn't needed locally), and everything is working perfectly.

<remove statusCode="503"/>

If I understand your problem well you want the following things:

1. Have your media files stored in one single git repository, which is used by many projects
2. If you modify a media file in any of the projects in your local machine, it should immediately appear in every other project (so you don't want to commit+push+pull all the time)

Unfortunately there is no ultimate solution for what you want, but there are some things by which you can make your life easier.

First you should decide one important thing: do you want to store for every version in your project repository a reference to the version of the media files? So for example if you have a project called example.com, do you need know which style.css it used 2 weeks ago, or the latest is always (or mostly) the best?

If you don't need to know that, the solution is easy:

1. create a repository for the media files and one for each project
2. create a symbolic link in your projects which point to the locally cloned media repository. You can either create a relative symbolic link (e.g. ../media) and assume that everybody will checkout the project so that the media directory is in the same place, or write the name of the symbolic link into .gitignore, and everybody can decide where he/she puts the media files.

In most of the cases, however, you want to know this versioning information. In this case you have two choices:

1. Store every project in one big repository. The advantage of this solution is that you will have only 1 copy of the media repository. The big disadvantage is that it is much harder to switch between project versions (if you checkout to a different version you will always modify ALL projects)

2. Use submodules (as explained in answer 1). This way you will store the media files in one repository, and the projects will contain only a reference to a specific media repo version. But this way you will normally have many local copies of the media repository, and you cannot easily modify a media file in all projects.

If I were you I would probably choose the first or third solution (symbolic links or submodules). If you choose to use submodules you can still do a lot of things to make your life easier:

1. Before committing you can rename the submodule directory and put a symlink to a common media directory. When you're ready to commit, you can remove the symlink and remove the submodule back, and then commit.

2. You can add one of your copy of the media repository as a remote repository to all of your projects.

You can add local directories as a remote this way:

cd /my/project2/media
git remote add project1 /my/project1/media

If you modify a file in /my/project1/media, you can commit it and pull it from /my/project2/media without pushing it to a remote server:

cd /my/project1/media
git commit -a -m "message"
cd /my/project2/media
git pull project1 master

You are free to remove these commits later (with git reset) because you haven't shared them with other users.

Solved my issue in Ubuntu 14.04 OS with python 2.7.6, by adding below two lines into ~/.bash_profile (or ~/.bashrc in unix) files.

source "/usr/local/bin/virtualenvwrapper.sh"

export WORKON_HOME="/opt/virtual_env/"

And then executing both these lines onto the terminal.

Based on my experience, the numpy docstring conventions (PEP257 superset) are the most widely-spread followed conventions that are also supported by tools, such as Sphinx.

One example:

Parameters
----------
x : type
    Description of parameter `x`.

In Swift 5 and Xcode 10.2

Please don't add custom bar button item, use this default behaviour.

No need of viewWillDisappear, no need of custom BarButtonItem etc...

It's better to detect when the VC is removed from it's parent.

Use any one of these two functions

override func willMove(toParent parent: UIViewController?) {
    super.willMove(toParent: parent)
    if parent == nil {
        callStatusDelegate?.backButtonClicked()//Here write your code
    }
}

override func didMove(toParent parent: UIViewController?) {
    super.didMove(toParent: parent)
    if parent == nil {
        callStatusDelegate?.backButtonClicked()//Here write your code
    }
}

If you want stop default behaviour of back button then add custom BarButtonItem.

you can use LocalDate:

Days.daysBetween(new LocalDate(start), new LocalDate(end)).getDays() 

This is working for me in Angular 7. It is based on the --main option of the ng command. I am not sure if this option is undocumented and possibly subject to change, but it works for me. I put a line in my package.json file in scripts section. There using the --main option of with the ng test command, I specify the path to the .spec.ts file I want to execute. For example

"test 1": "ng test --main E:/WebRxAngularClient/src/app/test/shared/my-date-utils.spec.ts",

You can run the script as you run any such script. I run it in Webstorm by clicking on "test 1" in the npm section.

Usage of pip for installation of packages in Python 3

Step 1: Install Python 3. Yes, by default an application file pip3.exe is already located there in the path (E.g.):

C:/Users/name/AppData/Local/Programs/Python/Python36-32/Scripts

Step 2: Go to

>Control Panel (Local Machine) > System > Advanced system settings >

>Click on `Environment Variables` >
Set a New User Variable, for this click `New` >
Write new 'Variable name' as "PYTHON_SCRIPTS" >
Copy that path of `pip3.exe` and paste within variable value > `OK` >

>Below again find out and click on `Path` under 'system variables' >
Edit this path >
Within 'Variable value' append and paste the same path of `pip3.exe` after putting a ';' >
Click `OK`/`Apply` and come out.

Step 3: Now, open cmd bash/shell by Pressing key Windows+R.

> Write 'pip3' and press 'Enter'. If pip3 is recognized you can go ahead.

Step 4: In this same cmd

> Write path of the `pip3.exe` followed by `/pip install 'package name'`

As Example just write:

C:/Users/name/AppData/Local/Programs/Python/Python36-32/Scripts/pip install matplotlib

Press Enter now. The Package matplotlib will start getting downloaded.

Further, for upgrading any package

Open cmd bash/shell again, then

type that path of pip3.exe followed by /pip install --upgrade 'package name' Press Enter.

As Example just write:

C:/Users/name/AppData/Local/Programs/Python/Python36-32/Scripts/pip install --upgrade matplotlib

Upgrading of the package will start :)

I would do this slightly different by applying both the UNPIVOT and the PIVOT functions to get the final result. The unpivot takes the values from both the totalcount and totalamount columns and places them into one column with multiple rows. You can then pivot on those results.:

select chardate,
  Australia_totalcount as [Australia # of Transactions], 
  Australia_totalamount as [Australia Total $ Amount],
  Austria_totalcount as [Austria # of Transactions], 
  Austria_totalamount as [Austria Total $ Amount]
from
(
  select 
    numericmonth, 
    chardate,
    country +'_'+col col, 
    value
  from
  (
    select numericmonth, 
      country, 
      chardate,
      cast(totalcount as numeric(10, 2)) totalcount,
      cast(totalamount as numeric(10, 2)) totalamount
    from mytransactions
  ) src
  unpivot
  (
    value
    for col in (totalcount, totalamount)
  ) unpiv
) s
pivot
(
  sum(value)
  for col in (Australia_totalcount, Australia_totalamount,
              Austria_totalcount, Austria_totalamount)
) piv
order by numericmonth

See SQL Fiddle with Demo.

If you have an unknown number of country names, then you can use dynamic SQL:

DECLARE @cols AS NVARCHAR(MAX),
    @colsName AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX)

select @cols = STUFF((SELECT distinct ',' + QUOTENAME(country +'_'+c.col) 
                      from mytransactions
                      cross apply 
                      (
                        select 'TotalCount' col
                        union all
                        select 'TotalAmount'
                      ) c
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

select @colsName 
    = STUFF((SELECT distinct ', ' + QUOTENAME(country +'_'+c.col) 
               +' as ['
               + country + case when c.col = 'TotalCount' then ' # of Transactions]' else 'Total $ Amount]' end
             from mytransactions
             cross apply 
             (
                select 'TotalCount' col
                union all
                select 'TotalAmount'
             ) c
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

set @query 
  = 'SELECT chardate, ' + @colsName + ' 
     from 
     (
      select 
        numericmonth, 
        chardate,
        country +''_''+col col, 
        value
      from
      (
        select numericmonth, 
          country, 
          chardate,
          cast(totalcount as numeric(10, 2)) totalcount,
          cast(totalamount as numeric(10, 2)) totalamount
        from mytransactions
      ) src
      unpivot
      (
        value
        for col in (totalcount, totalamount)
      ) unpiv
     ) s
     pivot 
     (
       sum(value)
       for col in (' + @cols + ')
     ) p 
     order by numericmonth'

execute(@query)

See SQL Fiddle with Demo

Both give the result:

I know, question is a bit old, but since am here looks like people are still looking for solutions.

I'll suggest you to use react-moment link,

react-moment comes with handy JSXtags which reduce a lot of work. Like in your case :-

import React  from 'react';
import Moment from 'react-moment';

exports default class MyComponent extends React.Component {
    render() {
        <Moment format="YYYY/MM/DD">{this.props.dateToFormat}</Moment>
    }
}

You might be confusing compilation from execution. Python has no compilation step! :) As soon as you type python myprogram.py the program runs and, in your case, tries to connect to an open port 5000, giving an error if no server program is listening there. It sounds like you are familiar with two-step languages, that require compilation to produce an executable — and thus you are confusing Python's runtime compilaint that “I can't find anyone listening on port 5000!” with a compile-time error. But, in fact, your Python code is fine; you just need to bring up a listener before running it!

One more option which I did not notice in the answers is using std::reduce which is introduced in c++17.

But you may notice many compilers not supporting it (Above GCC 10 may be good). But eventually the support will come.

With std::reduce, the advantage comes when using the execution policies. Specifying execution policy is optional. When the execution policy specified is std::execution::par, the algorithm may use hardware parallel processing capabilities. The gain may be more clear when using big size vectors.

Example:

//SAMPLE
std::vector<int> vec = {2,4,6,8,10,12,14,16,18};
    
//WITHOUT EXECUTION POLICY
int sum = std::reduce(vec.begin(),vec.end());
    
//TAKING THE ADVANTAGE OF EXECUTION POLICIES
int sum2 = std::reduce(std::execution::par,vec.begin(),vec.end());
    
std::cout << "Without execution policy  " << sum << std::endl;
std::cout << "With execution policy  " << sum2 << std::endl;

You need <numeric> header for std::reduce. And '<execution>' for execution policies.

I don't think emulator and simulator can be compared. Both mimic something, but are not part of the same scope of reasonning, they are not used in the same context.

In short: an emulator is designed to copy some features of the orginial and can even replace it in the real environment. A simulator is not desgined to copy the features of the original, but only to appear similar to the original to human beings. Without the features of the orginal, the simulator cannot replace it in the real environment.

An emulator is a device that mimics something close enough so that it can be substituted to the real thing. E.g you want a circuit to work like a ROM (read only memory) circuit, but also wants to adjust the content until it is what you want. You'll use a ROM emulator, a black box (likely to be CPU-based) with a physical and electrical interfaces compatible with the ROM you want to emulate. The emulator will be plugged into the device in place of the real ROM. The motherboard will not see any difference when working, but you will be able to change the emulated-ROM content easily. Said otherwise the emulator will act exactly as the actual thing in its motherboard context (maybe a little bit slower due to actual internal model) but there will be additional functions (like re-writing) visible only to the designer, out of the motherboard context. So emulator definition would be: something that mimic the original, has all of its functional features, can actually replace it to some extend in the real world, and may have additional features not visible in the normal context.

A simulator is used in another thinking context, e.g a plane simulator, a car simulator, etc. The simulation will take care only of some aspect of the actual thing, usually those related to how a human being will perceive and control it. The simulator will not perform the functions of the real stuff, and cannot be sustituted to it. The plane simulator will not fly or carry someone, it's not its purpose at all. The simulator is not intended to work, but to appear to the pilot somehow like the actual thing for purposes other than its normal ones, e.g. to allow ground training (including in unusual situations like all-engine failure). So simulator definition would be: something that can appear to human, to some extend, like the original, but cannot replace it for actual use. In addition the pilot will know that the simulator is a simulator.

I don't think we'll see any ROM simulator, because ROM are not interacting with human beings, nor we'll see any plane emulator, because planes cannot have a replacement performing the same functions in the real world.

In my view the model inside an emulator or a simulator can be anything, and has not to be similar to the model of the original. A ROM emulator model will likely be software instead of hardware, MS Flight Simulator cannot be more software than it is.

This comparison of both terms will contradict the currently selected answer (from Toybuilder) which puts the difference on the internal model, while my suggestion is that the difference is whether the fake can or cannot be used to perform the actual function in the actual world (to some accepted extend, indeed).

Note that the plane simulator will have also to simulate the earth, the sun, the wind, etc, which are not part of the plane, so a plane simulator will have to mimic some aspects of the plane, as well as the environment of the plane because it is not used in this actual environment, but in a training room.

This is a big difference with the emulator which emulates only the orginal, and its purpose is to be used in the environment of the original with no need to emulate it. Back to the plane context... what could be a plane emulator? Maybe a train that will connect two airports -- actually two plane steps -- carrying passengers, with stewardesses onboard, with car interior looking like an actual plane cabin, and with captain saying "ladies and gentlemen our altitude is currenlty 10 kms and the temperature at our destination is 24°C". Its benefit is difficult to see, hum...

As a conclusion, the emulator is a real thing intended to work, the simulator is a fake intended to trick the user.

I have tried all the solutions and this one worked for me

let temp = base64String.components(separatedBy: ",")
let dataDecoded : Data = Data(base64Encoded: temp[1], options: 
 .ignoreUnknownCharacters)!
let decodedimage = UIImage(data: dataDecoded)

yourImage.image = decodedimage

in jquery we have to use selector($) to declare variables

var test=$("<%=ddl.ClientId%>");

here we can get the id of drop down to j query variable

Here .persist() only will insert the record.If we use .merge() it will check is there any record exist with the current ID, If it exists, it will update otherwise it will insert a new record.

You can get access to the WhatsApp data base located on the SD card only as a root user I think. if you open "\data\data\com.whatsapp" you will see that "databases" is linked to "\firstboot\sqlite\com.whatsapp\"

FYI: A useful simulation tool - phpMyAdmin with Wampserver 3.0.6 - Preview SQL: I use 'Preview SQL' to see the SQL code that would be generated before you save the column with the change to ENUM. Preview SQL

Above you see that I have entered 'Ford','Toyota' into the ENUM but I am getting syntax ENUM(0) which is generating syntax error Query error 1064#

I then copy and paste and alter the SQL and run it through SQL with a positive result.

SQL changed

This is a quickfix that I use often and can also be used on existing ENUM values that need to be altered. Thought this might be useful.

Try using

DateTime.ParseExact(
    txtPaymentSummaryBeginDate.Text.Trim(),
    "MM/dd/yyyy", 
    System.Globalization.CultureInfo.InvariantCulture
);

It throws an exception if the input string is not in proper format, so in the catch section you can return false;

To enable the Windows Authentication on IIS7 on Windows 7 machine:

Any applications that require CPU usage such as transcoding, display performance and media rendering, whether it be audio or visual, will certainly require (at this point) and benefit from using 64 bit versus 32 bit due to the CPU's ability to deal with the sheer amount of data being thrown at it. It's not so much a question of address space as it is the way the data is being dealt with. A 64 bit processor, given 64 bit code, is going to perform better, especially with mathematically difficult things like transcoding and VoIP data - in fact, any sort of 'math' applications should benefit by the usage of 64 bit CPUs and operating systems. Prove me wrong.

If they are in the same controller class, it would be:

foreach ( $characters as $character) {
    $num += $this->getFactorial($index) * $index;
    $index ++;
}

Otherwise you need to create a new instance of the class, and call the method, ie:

$controller = new MyController();
foreach ( $characters as $character) {
    $num += $controller->getFactorial($index) * $index;
    $index ++;
}

If you application is using setting such as Asp.net ConnectionString you need to add the attribute HostType to your method, else they wont load even if you have an App.Config file.

[TestMethod]
[HostType("ASP.NET")] // will load the ConnectionString from the App.Config file
public void Test() {

}

A good plugin that I have used before is DataTables.

The best way to get a browser's default styling on something is to not style the element at all in the first place.

A simple option using plt.gca() to get current axes and set aspect

        plt.gca().set_aspect('equal')

in place of your last line

Default in Debian 8.1 and PostgreSQL 9.4 after the installation with the package manager apt-get

ps auxw |  grep postgres | grep -- -D
postgres 17340  0.0  0.5 226700 21756 ?        S    09:50   0:00 /usr/lib/postgresql/9.4/bin/postgres -D /var/lib/postgresql/9.4/main -c config_file=/etc/postgresql/9.4/main/postgresql.conf

so apparently /var/lib/postgresql/9.4/main.

I personally think Array.from is a more readable solution. By the way, just beware of its browser support.

// clone
let x = [1, 2, 3];
let y = Array.from(x);
console.log({y});

// deep clone
let clone = arr => Array.from(arr, item => Array.isArray(item) ? clone(item) : item);
x = [1, [], [[]]];
y = clone(x);
console.log({y});

If you use box-sizing: border-box means not only border, padding,margin, etc. All element will come inside of the parent element.

div p {_x000D_
    box-sizing: border-box;_x000D_
    -moz-box-sizing: border-box;_x000D_
    -webkit-box-sizing: border-box;_x000D_
    width: 150px;_x000D_
    height:100%;_x000D_
    border: 20px solid #f00;_x000D_
    background-color: #00f;_x000D_
    color:#fff;_x000D_
    padding: 10px;_x000D_
  _x000D_
}

<div>_x000D_
  <p>It was popularised in the 1960s with the release of Letraset sheets</p>_x000D_
</div>

The simple solution is follow this screenshot then crash will go away:

Noted: This is Xcode 11.5

I recommend use boolean;. You have to install the boolean module from cpan though.

Just use target on your tag <a>

<a href="newsletter_01.pdf" target="_blank">Read more</a>

The target attribute specifies where to open the link. Using "_blank" will make your browser to open a new window/tab.

You could also use target in many ways. See http://www.w3schools.com/tags/att_a_target.asp

header('Content-type: text/plain; charset=utf-8');

I'm resurrecting the dead here, but because a range can be defined as "A:A", using a for each loop ends up with a potential infinite loop. The solution, as far as I know, is to use the Do Until loop.

Do Until Selection.Value = ""
  Rem Do things here...
Loop

I found one Solution :

echo iconv('UTF-8', 'ASCII//TRANSLIT', utf8_encode($string));

use utf8_encode()

Html:

<input type="file" name="input-file" id="input-file">

jQuery:

var fileToUpload = $('#input-file').prop('files')[0];

We want to get first element only, because prop('files') returns array.

You could get first rows of Spark DataFrame with head and then create Pandas DataFrame:

l = [('Alice', 1),('Jim',2),('Sandra',3)]
df = sqlContext.createDataFrame(l, ['name', 'age'])

df_pandas = pd.DataFrame(df.head(3), columns=df.columns)

In [4]: df_pandas
Out[4]: 
     name  age
0   Alice    1
1     Jim    2
2  Sandra    3

or via css, which is the preferred method any more...

<td style="text-align: center;">

We have found that adding the Apptentive cocoa pod to an existing Xcode project may potentially not include some of our required frameworks.

Check your linker flags:

Target > Build Settings > Other Linker Flags 

You should see -lApptentiveConnect listed as a linker flag:

... -ObjC -lApptentiveConnect ... 

You should also see our required Frameworks listed:

• Accelerate
• CoreData
• CoreText
• CoreGraphics
• CoreTelephony
• Foundation
• QuartzCore
• StoreKit
• SystemConfiguration

• UIKit

  -ObjC -lApptentiveConnect -framework Accelerate -framework CoreData -framework CoreGraphics -framework CoreText -framework Foundation -framework QuartzCore -framework SystemConfiguration -framework UIKit -framework CoreTelephony -framework StoreKit  

For specific month and year use date() as natural language as following

$first_date = date('d-m-Y',strtotime('first day of april 2010'));
$last_date = date('d-m-Y',strtotime('last day of april 2010'));
// Isn't it simple way?

but for Current month

$first_date = date('d-m-Y',strtotime('first day of this month'));
$last_date = date('d-m-Y',strtotime('last day of this month'));

You will add button column like this in your dataGridView

        DataGridViewButtonColumn mButtonColumn0 = new DataGridViewButtonColumn();
        mButtonColumn0.Name = "ColumnA";
        mButtonColumn0.Text = "ColumnA";


        if (dataGridView.Columns["ColumnA"] == null)
        {
            dataGridView.Columns.Insert(2, mButtonColumn0);
        }

Then you can add some actions inside cell click event. I found this is easiest way of doing it.

    private void dataGridView_CellClick(object sender, DataGridViewCellEventArgs e)
    {

        int rowIndex = e.RowIndex;
        int columnIndex = e.ColumnIndex;

        if (dataGridView.Rows[rowIndex].Cells[columnIndex].Selected == true && dataGridView.Columns[columnIndex].Name == "ColumnA")
         {
               //.... do any thing here.
         }


    }

I found that Cell Click event is automatically subscribed often. So I did not need this code below. However, if your cell click event is not subscribed, then add this line of code for your dataGridView.

     this.dataGridView.CellClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.dataGridView_CellClick);

$(document).ready(function() {
  $('#div_one').bind('click', function() {
    $('#div_two').addClass('large');
  });
});

If I understood your question.

Or you can modify css directly:

var $speech = $('div.speech');
var currentSize = $speech.css('fontSize');
$speech.css('fontSize', '10px');

For Chrome, instead of

response.AppendHeader("X-Frame-Options", "ALLOW-FROM " + host);

you need to add Content-Security-Policy

string selfAuth = System.Web.HttpContext.Current.Request.Url.Authority;
string refAuth = System.Web.HttpContext.Current.Request.UrlReferrer.Authority;
response.AppendHeader("Content-Security-Policy", "default-src 'self' 'unsafe-inline' 'unsafe-eval' data: *.msecnd.net vortex.data.microsoft.com " + selfAuth + " " + refAuth);

to the HTTP-response-headers.
Note that this assumes you checked on the server whether or not refAuth is allowed.
And also, note that you need to do browser-detection in order to avoid adding the allow-from header for Chrome (outputs error on console).

When you log in to your developer account, you can find a link at the bottom of the download section for Xcode that says "Looking for an older version of Xcode?". In there you can find download links to older versions of Xcode and other developer tools

The -p flag of netstat gives you PID of the process:

netstat -l -p

Edit: The command that is needed to get PIDs of socket users in FreeBSD is sockstat. As we worked out during the discussion with @Cyclone, the line that does the job is:

sockstat -4 -l | grep :80 | awk '{print $3}' | head -1

You can get key hash from SHA-1 key. Its very simple you need to get your SHA-1(Signed APK) key from Play Store check below image.

Now Copy that SHA-1 key and past it in this website http://tomeko.net also check below image to get your Key Hash.

Add

tools:ignore="ContentDescription"

to your image. Make sure you have xmlns:tools="http://schemas.android.com/tools" . in your root layout.

In my case, I did Build > Clean Project and it worked!

git rm --cached file will remove the file from the stage. That is, when you commit the file will be removed. git reset HEAD -- file will simply reset file in the staging area to the state where it was on the HEAD commit, i.e. will undo any changes you did to it since last commiting. If that change happens to be newly adding the file, then they will be equivalent.

The other answers are for AWS SDK v1. Here is a method for AWS SDK v2 (currently 2.3.9).

Note that getObjectMetadata and doesObjectExist methods are not currently in the v2 SDK! So those are no longer options. We are forced to use either getObject or listObjects.

listObjects calls are currently 12.5 times more expensive to make than getObject. But AWS also charges for any data downloaded, which raises the price of getObject if the file exists. As long as the file is very unlikely to exist (for example, you have generated a new UUID key randomly and just need to double-check that it isn't taken) then calling getObject is significantly cheaper by my calculation.

Just to be on the safe side though, I added a range() specification to ask AWS to only send a few bytes of the file. As far as I know the SDK will always respect this and not charge you for downloading the whole file. But I haven't verified that so rely on that behavior at your own risk! (Also, I'm not sure what how range behaves if the S3 object is 0 bytes long.)

    private boolean sanityCheckNewS3Key(String bucket, String key) {

        ResponseInputStream<GetObjectResponse> resp = null;
        try {
            resp = s3client.getObject(GetObjectRequest.builder()
                .bucket(bucket)
                .key(key)
                .range("bytes=0-3")
                .build());
        }
        catch (NoSuchKeyException e) {
            return false;
        }
        catch (AwsServiceException se) {
            throw se;
        }
        finally {
            if (resp != null) {
                try {
                    resp.close();
                } catch (IOException e) {
                    log.warn("Exception while attempting to close S3 input stream", e);
                }
            }
        }
        return true;
    }
}

Note: this code assumes s3Client and log are declared and initialized elsewhere. Method returns a boolean, but can throw exceptions.

A great substitute for np.isnan() and pd.isnull() is

for i in range(0,a.shape[0]):
    if(a[i]!=a[i]):
       //do something here
       //a[i] is nan

since only nan is not equal to itself.

Old question but I should warn:

Do NOT use .split('')

You'll get weird results with non-BMP (non-Basic-Multilingual-Plane) character sets.

Reason is that methods like .split() and .charCodeAt() only respect the characters with a code point below 65536; bec. higher code points are represented by a pair of (lower valued) "surrogate" pseudo-characters.

''.length     // —> 6
''.split('')  // —> ["?", "?", "?", "?", "?", "?"]

''.length      // —> 2
''.split('')   // —> ["?", "?"]

Use ES2015 (ES6) features where possible:

Using the spread operator:

let arr = [...str];

Or Array.from

let arr = Array.from(str);

Or split with the new u RegExp flag:

let arr = str.split(/(?!$)/u);

Examples:

[...'']        // —> ["", "", ""]
[...'']     // —> ["", "", ""]

For ES5, options are limited:

I came up with this function that internally uses MDN example to get the correct code point of each character.

function stringToArray() {
  var i = 0,
    arr = [],
    codePoint;
  while (!isNaN(codePoint = knownCharCodeAt(str, i))) {
    arr.push(String.fromCodePoint(codePoint));
    i++;
  }
  return arr;
}

This requires knownCharCodeAt() function and for some browsers; a String.fromCodePoint() polyfill.

if (!String.fromCodePoint) {
// ES6 Unicode Shims 0.1 , © 2012 Steven Levithan , MIT License
    String.fromCodePoint = function fromCodePoint () {
        var chars = [], point, offset, units, i;
        for (i = 0; i < arguments.length; ++i) {
            point = arguments[i];
            offset = point - 0x10000;
            units = point > 0xFFFF ? [0xD800 + (offset >> 10), 0xDC00 + (offset & 0x3FF)] : [point];
            chars.push(String.fromCharCode.apply(null, units));
        }
        return chars.join("");
    }
}

Examples:

stringToArray('')     // —> ["", "", ""]
stringToArray('')  // —> ["", "", ""]

Note: str[index] (ES5) and str.charAt(index) will also return weird results with non-BMP charsets. e.g. ''.charAt(0) returns "?".
