The below code will kill all iChat oriented programs:

p = subprocess.Popen(['pgrep', '-l' , 'iChat'], stdout=subprocess.PIPE)
out, err = p.communicate()

for line in out.splitlines():        
    line = bytes.decode(line)
    pid = int(line.split(None, 1)[0])
    os.kill(pid, signal.SIGKILL)

You should add fstream::out to open method like this:

file.open("test.txt",fstream::out);

More information about fstream flags, check out this link: http://www.cplusplus.com/reference/fstream/fstream/open/

Layer draws out of clip region, you need to set it to mask to bounds:

self.mainImageView.layer.masksToBounds = true

From the docs:

By default, the corner radius does not apply to the image in the layer’s contents property; it applies only to the background color and border of the layer. However, setting the masksToBounds property to true causes the content to be clipped to the rounded corners

I found a very clear example here which explains how the 'control is inverted'.

Classic code (without Dependency injection)

Here is how a code not using DI will roughly work:

• Application needs Foo (e.g. a controller), so:
• Application creates Foo
• Application calls Foo
  • Foo needs Bar (e.g. a service), so:
  • Foo creates Bar
  • Foo calls Bar
    • Bar needs Bim (a service, a repository, …), so:
    • Bar creates Bim
    • Bar does something

Using dependency injection

Here is how a code using DI will roughly work:

• Application needs Foo, which needs Bar, which needs Bim, so:
• Application creates Bim
• Application creates Bar and gives it Bim
• Application creates Foo and gives it Bar
• Application calls Foo
  • Foo calls Bar
    • Bar does something

The control of the dependencies is inverted from one being called to the one calling.

What problems does it solve?

Dependency injection makes it easy to swap with the different implementation of the injected classes. While unit testing you can inject a dummy implementation, which makes the testing a lot easier.

Ex: Suppose your application stores the user uploaded file in the Google Drive, with DI your controller code may look like this:

class SomeController
{
    private $storage;

    function __construct(StorageServiceInterface $storage)
    {
        $this->storage = $storage;
    }

    public function myFunction () 
    {
        return $this->storage->getFile($fileName);
    }
}

class GoogleDriveService implements StorageServiceInterface
{
    public function authenticate($user) {}
    public function putFile($file) {}
    public function getFile($file) {}
}

When your requirements change say, instead of GoogleDrive you are asked to use the Dropbox. You only need to write a dropbox implementation for the StorageServiceInterface. You don't have make any changes in the controller as long as Dropbox implementation adheres to the StorageServiceInterface.

While testing you can create the mock for the StorageServiceInterface with the dummy implementation where all the methods return null(or any predefined value as per your testing requirement).

Instead if you had the controller class to construct the storage object with the new keyword like this:

class SomeController
{
    private $storage;

    function __construct()
    {
        $this->storage = new GoogleDriveService();
    }

    public function myFunction () 
    {
        return $this->storage->getFile($fileName);
    }
}

When you want to change with the Dropbox implementation you have to replace all the lines where new GoogleDriveService object is constructed and use the DropboxService. Besides when testing the SomeController class the constructor always expects the GoogleDriveService class and the actual methods of this class are triggered.

When is it appropriate and when not? In my opinion you use DI when you think there are (or there can be) alternative implementations of a class.

another way, will also work on MySQL and PostgreSQL

select TABLE_NAME from INFORMATION_SCHEMA.TABLES
where TABLE_TYPE = 'BASE TABLE'

git Stash list 

List will show all stashed items eg:stash@{0}:,stash@{1}:,..,stash@{n}:

Then select the number n which denotes stash@{n}:

git stash apply n 

for example:

git stash apply 1 

will apply that particular stashed changes to the current branch

public event EventHandler ImageFullPath1Changed;

public string ImageFullPath1
{
    get
    {
        // insert getter logic
    }
    set
    {
        // insert setter logic       

        // EDIT -- this example is not thread safe -- do not use in production code
        if (ImageFullPath1Changed != null && value != _backingField)
            ImageFullPath1Changed(this, new EventArgs(/*whatever*/);
    }
}                        

That said, I completely agree with Ryan. This scenario is precisely why INotifyPropertyChanged exists.

Probably a little late to post my answer here but still I'll post, it might benefit someone though,

I had faced the same problem,

The main reason being that I created the virtualenv as a "root" user But later was trying to activate it using another user.

chmod won't work as you're not the owner of the file, hence the alternative is to use chown (to change the ownership)

For e.g. :

If you have your virtualenv created at /home/abc/ENV

Then CD to /home/abc

and run the command : chown -Rv [user-to-whom-you want-change-ownership] [folder/filename whose ownership needs to be changed]

In this example the commands would be : chown -Rv abc ENV

After the ownership is successfully changed you can simply run source /ENV/bin/./activate and your should be able to activate the virtualenv correctly.

This is because (100/500) is an integer expression yielding 0.

Try

per = 100.0 * tota / 500

there's no need for the float() call, since using a floating-point literal (100.0) will make the entire expression floating-point anyway.

I used this method to clear the image from picturebox. It may help some one

private void btnClear1_Click(object sender, EventArgs e)
        {

            img1.ImageLocation = null;
        }

You need to pass your components as children, like this:

var App = require('./App.js');
var SampleComponent = require('./SampleComponent.js');
ReactDOM.render(
    <App>
        <SampleComponent name="SomeName"/> 
    <App>, 
    document.body
);

And then append them in the component's body:

var App = React.createClass({
    render: function() {
        return (
            <div>
                <h1>App main component! </h1>
                {
                    this.props.children
                }
            </div>
        );
    }
});

You don't need to manually manipulate HTML code, React will do that for you. If you want to add some child components, you just need to change props or state it depends. For example:

var App = React.createClass({

    getInitialState: function(){
        return [
            {id:1,name:"Some Name"}
        ]
    },

    addChild: function() {
        // State change will cause component re-render
        this.setState(this.state.concat([
            {id:2,name:"Another Name"}
        ]))
    }

    render: function() {
        return (
            <div>
                <h1>App main component! </h1>
                <button onClick={this.addChild}>Add component</button>
                {
                    this.state.map((item) => (
                        <SampleComponent key={item.id} name={item.name}/>
                    ))
                }
            </div>
        );
    }

});

Here is the code of ReadDoc/docx.java: This will read a dox/docx file and print its content to the console. you can customize it your way.

import java.io.*;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.extractor.WordExtractor;

public class ReadDocFile
{
    public static void main(String[] args)
    {
        File file = null;
        WordExtractor extractor = null;
        try
        {

            file = new File("c:\\New.doc");
            FileInputStream fis = new FileInputStream(file.getAbsolutePath());
            HWPFDocument document = new HWPFDocument(fis);
            extractor = new WordExtractor(document);
            String[] fileData = extractor.getParagraphText();
            for (int i = 0; i < fileData.length; i++)
            {
                if (fileData[i] != null)
                    System.out.println(fileData[i]);
            }
        }
        catch (Exception exep)
        {
            exep.printStackTrace();
        }
    }
}

The solution i'm using is as follows and allows you to set the active class per php page.

Give each of your menu items a unique class, i use .nav-x (nav-about, here).

<li class="nav-item nav-about"> <a class="nav-link" href="about.php">About</a> </li>

At the top of each page (about.php here):

<!-- Navbar Active Class -->
<?php $activeClass = '.nav-about > a'; ?>

Elsewhere (header.php / index.php):

<style>
<?php echo $activeClass; ?> {
    color: #fff !important;
}
</style>

Simply change the .nav-about > a per page, .nav-forum > a, for example.

If you want different styling (colors etc) for each nav item, just attach the inline styling to that page instead of the index / header page.

I was getting this problem while using a tunnel because I:

1. had the tunnel url:port set in the FB app settings
2. but was accessing the local server by pointing my browser to "http://localhost:3000"

once i started punching the tunnel url:port into the browser, i was good to go.

i'm using Rails and Facebooker, but might help others just the same.

 arrList.set(5,newValue);

and if u want to update it then add this line also

 youradapater.NotifyDataSetChanged();

Project Settings > Under "Targets", select your project > Build Phases > open "Compile Sources" and "Copy Bundle Resources". Check if any files are listed in red color. If so , just delete it. Then clean and run.

Worked for me.

I also needed the current screen dimension, specifically the Work-area, which returned the rectangle excluding the Taskbar width.

I used it in order to reposition a window, which is opened to the right and down to where the mouse is positioned. Since the window is fairly large, in many cases it got out of the screen bounds. The following code is based on @e-j answer: This will give you the current screen.... The difference is that I also show my repositioning algorithm, which I assume is actually the point.

The code:

using System.Windows;
using System.Windows.Forms;

namespace MySample
{

    public class WindowPostion
    {
        /// <summary>
        /// This method adjust the window position to avoid from it going 
        /// out of screen bounds.
        /// </summary>
        /// <param name="topLeft">The requiered possition without its offset</param>
        /// <param name="maxSize">The max possible size of the window</param>
        /// <param name="offset">The offset of the topLeft postion</param>
        /// <param name="margin">The margin from the screen</param>
        /// <returns>The adjusted position of the window</returns>
        System.Drawing.Point Adjust(System.Drawing.Point topLeft, System.Drawing.Point maxSize, int offset, int margin)
        {
            Screen currentScreen = Screen.FromPoint(topLeft);
            System.Drawing.Rectangle rect = currentScreen.WorkingArea;

            // Set an offset from mouse position.
            topLeft.Offset(offset, offset);

            // Check if the window needs to go above the task bar, 
            // when the task bar shadows the HUD window.
            int totalHight = topLeft.Y + maxSize.Y + margin;

            if (totalHight > rect.Bottom)
            {
                topLeft.Y -= (totalHight - rect.Bottom);

                // If the screen dimensions exceed the hight of the window
                // set it just bellow the top bound.
                if (topLeft.Y < rect.Top)
                {
                    topLeft.Y = rect.Top + margin;
                }
            }

            int totalWidth = topLeft.X + maxSize.X + margin;
            // Check if the window needs to move to the left of the mouse, 
            // when the HUD exceeds the right window bounds.
            if (totalWidth > rect.Right)
            {
                // Since we already set an offset remove it and add the offset 
                // to the other side of the mouse (2x) in addition include the 
                // margin.
                topLeft.X -= (maxSize.X + (2 * offset + margin));

                // If the screen dimensions exceed the width of the window
                // don't exceed the left bound.
                if (topLeft.X < rect.Left)
                {
                    topLeft.X = rect.Left + margin;
                }
            }

            return topLeft;
        }
    }
}

Some explanations:

1) topLeft - position of the top left at the desktop (works                     
   for multi screens - with different aspect ratio).                            
            Screen1              Screen2

   If the mouse is in Screen3 a possible value might be:                        
   topLeft.X=4140 topLeft.Y=195                                                 
2) offset - the offset from the top left, one value for both                    
   X and Y directions.                                                          
3) maxSize - the maximal size of the window - including its                     
   size when it is expanded - from the following example                        
   we need maxSize.X = 200, maxSize.Y = 150 - To avoid the expansion            
   being out of bound.

• I had no choice but using the code format (otherwise the white spaces would have been lost).
• Originally this appeared in the code above as a <remark><code>...</code></remark>

Are you sure your web service is deployed correctly to the enviornment that is NOT working. Looks like the type is out of date.

You could do that in a single statement

cat("hello","world",file="output.txt",sep="\n",append=TRUE)

The difference in assignment operators is clearer when you use them to set an argument value in a function call. For example:

median(x = 1:10)
x   
## Error: object 'x' not found

In this case, x is declared within the scope of the function, so it does not exist in the user workspace.

median(x <- 1:10)
x    
## [1]  1  2  3  4  5  6  7  8  9 10

In this case, x is declared in the user workspace, so you can use it after the function call has been completed.

There is a general preference among the R community for using <- for assignment (other than in function signatures) for compatibility with (very) old versions of S-Plus. Note that the spaces help to clarify situations like

x<-3
# Does this mean assignment?
x <- 3
# Or less than?
x < -3

Most R IDEs have keyboard shortcuts to make <- easier to type. Ctrl + = in Architect, Alt + - in RStudio (Option + - under macOS), Shift + - (underscore) in emacs+ESS.

If you prefer writing = to <- but want to use the more common assignment symbol for publicly released code (on CRAN, for example), then you can use one of the tidy_* functions in the formatR package to automatically replace = with <-.

library(formatR)
tidy_source(text = "x=1:5", arrow = TRUE)
## x <- 1:5

The answer to the question "Why does x <- y = 5 throw an error but not x <- y <- 5?" is "It's down to the magic contained in the parser". R's syntax contains many ambiguous cases that have to be resolved one way or another. The parser chooses to resolve the bits of the expression in different orders depending on whether = or <- was used.

To understand what is happening, you need to know that assignment silently returns the value that was assigned. You can see that more clearly by explicitly printing, for example print(x <- 2 + 3).

Secondly, it's clearer if we use prefix notation for assignment. So

x <- 5
`<-`(x, 5)  #same thing

y = 5
`=`(y, 5)   #also the same thing

The parser interprets x <- y <- 5 as

`<-`(x, `<-`(y, 5))

We might expect that x <- y = 5 would then be

`<-`(x, `=`(y, 5))

but actually it gets interpreted as

`=`(`<-`(x, y), 5)

This is because = is lower precedence than <-, as shown on the ?Syntax help page.

Trying with a different version of gcc worked for me - gcc 4.9 in my case.

Answer is already given above. Trying to differentiate between strong vs week and static vs dynamic concept.

What is Strongly typed VS Weakly typed?

Strongly Typed: Will not be automatically converted from one type to another

In Go or Python like strongly typed languages "2" + 8 will raise a type error, because they don't allow for "type coercion".

Weakly (loosely) Typed: Will be automatically converted to one type to another: Weakly typed languages like JavaScript or Perl won't throw an error and in this case JavaScript will results '28' and perl will result 10.

Perl Example:

my $a = "2" + 8;
print $a,"\n";

Save it to main.pl and run perl main.pl and you will get output 10.

What is Static VS Dynamic type?

In programming, programmer define static typing and dynamic typing with respect to the point at which the variable types are checked. Static typed languages are those in which type checking is done at compile-time, whereas dynamic typed languages are those in which type checking is done at run-time.

• Static: Types checked before run-time
• Dynamic: Types checked on the fly, during execution

What is this means?

In Go it checks typed before run-time (static check). This mean it not only translates and type-checks code it’s executing, but it will scan through all the code and type error would be thrown before the code is even run. For example,

package main

import "fmt"

func foo(a int) {
    if (a > 0) {
        fmt.Println("I am feeling lucky (maybe).")
    } else {
        fmt.Println("2" + 8)
    }
}

func main() {
    foo(2)
}

Save this file in main.go and run it, you will get compilation failed message for this.

go run main.go
# command-line-arguments
./main.go:9:25: cannot convert "2" (type untyped string) to type int
./main.go:9:25: invalid operation: "2" + 8 (mismatched types string and int)

But this case is not valid for Python. For example following block of code will execute for first foo(2) call and will fail for second foo(0) call. It's because Python is dynamically typed, it only translates and type-checks code it’s executing on. The else block never executes for foo(2), so "2" + 8 is never even looked at and for foo(0) call it will try to execute that block and failed.

def foo(a):
    if a > 0:
        print 'I am feeling lucky.'
    else:
        print "2" + 8
foo(2)
foo(0)

You will see following output

python main.py
I am feeling lucky.
Traceback (most recent call last):
  File "pyth.py", line 7, in <module>
    foo(0)
  File "pyth.py", line 5, in foo
    print "2" + 8
TypeError: cannot concatenate 'str' and 'int' objects

Based on Don W's solution, with fewer variables.

void process_mem_usage(double& vm_usage, double& resident_set)
{
    vm_usage     = 0.0;
    resident_set = 0.0;

    // the two fields we want
    unsigned long vsize;
    long rss;
    {
        std::string ignore;
        std::ifstream ifs("/proc/self/stat", std::ios_base::in);
        ifs >> ignore >> ignore >> ignore >> ignore >> ignore >> ignore >> ignore >> ignore >> ignore >> ignore
                >> ignore >> ignore >> ignore >> ignore >> ignore >> ignore >> ignore >> ignore >> ignore >> ignore
                >> ignore >> ignore >> vsize >> rss;
    }

    long page_size_kb = sysconf(_SC_PAGE_SIZE) / 1024; // in case x86-64 is configured to use 2MB pages
    vm_usage = vsize / 1024.0;
    resident_set = rss * page_size_kb;
}

Use,

var url = $(this).attr('href');
window.open(url, '_blank');

Update:the href is better off being retrieved with prop since it will return the full url and it's slightly faster.

var url = $(this).prop('href');

That is because, of course, there is no ACTUAL page height. Keep in mind that you scroll throughout the contents of a page vertically not horizontally, creating a limited width but unlimited height. What the selected answer did was to make the table take up the visible area and stay there no matter what(absolute positioning).So theoretically what you were trying to do was impossible

In Windows Vista and later the HTTP WCF service stuff would cause the exception you mentioned because a restricted account does not have right for that. That is the reason why it worked when you ran it as administrator.

Every sensible developer must use a RESTRICTED account rather than as an Administrator, yet many people go the wrong way and that is precisely why there are so many applications out there that DEMAND admin permissions when they are not really required. Working the lazy way results in lazy solutions. I hope you still work in a restricted account (my congratulations).

There is a tool out there (from 2008 or so) called NamespaceManagerTool if I remember correctly that is supposed to grant the restricted user permissions on these service URLs that you define for WCF. I haven't used that though...

Include the attribute Method="text" on the xsl:output tag and include newlines in your literal content in the XSL at the appropriate points. If you prefer to keep the source code of your XSL tidy use the entity 
 where you want a new line.

You can Implement this also:- setPage(1, n); where, n = any number.

$products = Mage::getResourceModel('catalog/product_collection')
                ->addAttributeToSelect('*')
                ->addAttributeToSelect(array('name', 'price', 'small_image'))
                ->addFieldToFilter('visibility', Mage_Catalog_Model_Product_Visibility::VISIBILITY_BOTH) //visible only catalog & searchable product
                ->addAttributeToFilter('status', 1) // enabled
                ->setStoreId($storeId)
                ->setOrder('created_at', 'desc')
                ->setPage(1, 6);

You are using jQuery(document).ready(function($) {} means here you are using jQuery instead of $. So to resolve your issue use following code.

jQuery("#submittername").text(submitter_name);

This will resolve your problem.

Whatever they write, have them step through it in a debugger line-by-line on the first run. Let them see for themselves what the computer is doing. This takes a lot of mystery out of things, reduces intimidation ("oh, each line really is that simple!"), and helps them learn debugging skills and recognize why common errors are common (and why they're errors)

Another alternative is Guava which has an easy-to-use suite of Hashing utilities. For example, to hash a string using SHA256 as a hex-string you would simply do:

final String hashed = Hashing.sha256()
        .hashString("your input", StandardCharsets.UTF_8)
        .toString();

You can create a new model to Deserialize your Json CustomerJson:

public class CustomerJson
{
    [JsonProperty("customer")]
    public Customer Customer { get; set; }
}

public class Customer
{
    [JsonProperty("first_name")]
    public string Firstname { get; set; }

    [JsonProperty("last_name")]
    public string Lastname { get; set; }

    ...
}

And you can deserialize your json easily :

JsonConvert.DeserializeObject<List<CustomerJson>>(json);

Hope it helps !

Documentation: Serializing and Deserializing JSON

Library functions like "pow" are usually carefully crafted to yield the minimum possible error (in generic case). This is usually achieved approximating functions with splines (according to Pascal's comment the most common implementation seems to be using Remez algorithm)

fundamentally the following operation:

pow(x,y);

has a inherent error of approximately the same magnitude as the error in any single multiplication or division.

While the following operation:

float a=someValue;
float b=a*a*a*a*a*a;

has a inherent error that is greater more than 5 times the error of a single multiplication or division (because you are combining 5 multiplications).

The compiler should be really carefull to the kind of optimization it is doing:

1. if optimizing pow(a,6) to a*a*a*a*a*a it may improve performance, but drastically reduce the accuracy for floating point numbers.
2. if optimizing a*a*a*a*a*a to pow(a,6) it may actually reduce the accuracy because "a" was some special value that allows multiplication without error (a power of 2 or some small integer number)
3. if optimizing pow(a,6) to (a*a*a)*(a*a*a) or (a*a)*(a*a)*(a*a) there still can be a loss of accuracy compared to pow function.

In general you know that for arbitrary floating point values "pow" has better accuracy than any function you could eventually write, but in some special cases multiple multiplications may have better accuracy and performance, it is up to the developer choosing what is more appropriate, eventually commenting the code so that noone else would "optimize" that code.

The only thing that make sense (personal opinion, and apparently a choice in GCC wichout any particular optimization or compiler flag) to optimize should be replacing "pow(a,2)" with "a*a". That would be the only sane thing a compiler vendor should do.

ASP.NET Core

Routing is configured in the Configure method of the Startup class. To set the "homepage" simply add the following. This will cause users to be routed to the controller and action defined in the MapRoute method when/if they navigate to your site’s base URL, i.e., yoursite.com will route users to yoursite.com/foo/index:

app.UseMvc(routes =>
{
   routes.MapRoute(
   name: "default",
   template: "{controller=FooController}/{action=Index}/{id?}");
});

Pre-ASP.NET Core

Use the RegisterRoutes method located in either App_Start/RouteConfig.cs (MVC 3 and 4) or Global.asax.cs (MVC 1 and 2) as shown below. This will cause users to be routed to the controller and action defined in the MapRoute method if they navigate to your site’s base URL, i.e., yoursite.com will route the user to yoursite.com/foo/index:

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    // Here I have created a custom "Default" route that will route users to the "YourAction" method within the "FooController" controller.
    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "FooController", action = "Index", id = UrlParameter.Optional }
    );
}

I would strongly recommend using SourceTree from Atlassian. (It's free.) It makes this trivial. You can stage individual hunks of code or individual lines of code quickly and easily.

just a moment ago, i came across with the same issue. and i resolve it in the following manner.

Response.Redirect("../index.aspx?Name="+this.textName.Text+"&LastName="+this.textlName.Text);

Yes there still is no API for this (2.1). But it seemed like at WWDC a lot of people were already interested in the functionality (including myself) and the recommendation was to go to the below site and create a feature request for this. If there is enough of an interest, they might end up moving the ICal.framework to the public SDK.

Change the key of the component.

<Component key="1" />

<Component key="2" />

Component will be unmounted and a new instance of Component will be mounted since the key has changed.

edit: Documented on You Probably Don't Need Derived State:

When a key changes, React will create a new component instance rather than update the current one. Keys are usually used for dynamic lists but are also useful here.

I got lucky and answered this in a comment to the question, but I'm posting a full answer for the sake of completeness and so we can mark this question as "Answered".

It depends on what you want to accomplish by sharing a controller; you can either share the same controller (though have different instances), or you can share the same controller instance.

Share a Controller

Two directives can use the same controller by passing the same method to two directives, like so:

app.controller( 'MyCtrl', function ( $scope ) {
  // do stuff...
});

app.directive( 'directiveOne', function () {
  return {
    controller: 'MyCtrl'
  };
});

app.directive( 'directiveTwo', function () {
  return {
    controller: 'MyCtrl'
  };
});

Each directive will get its own instance of the controller, but this allows you to share the logic between as many components as you want.

Require a Controller

If you want to share the same instance of a controller, then you use require.

require ensures the presence of another directive and then includes its controller as a parameter to the link function. So if you have two directives on one element, your directive can require the presence of the other directive and gain access to its controller methods. A common use case for this is to require ngModel.

^require, with the addition of the caret, checks elements above directive in addition to the current element to try to find the other directive. This allows you to create complex components where "sub-components" can communicate with the parent component through its controller to great effect. Examples could include tabs, where each pane can communicate with the overall tabs to handle switching; an accordion set could ensure only one is open at a time; etc.

In either event, you have to use the two directives together for this to work. require is a way of communicating between components.

Check out the Guide page of directives for more info: http://docs.angularjs.org/guide/directive

Check out Apache Commons FileUtils (listFiles, iterateFiles, etc.). Nice convenience methods for doing what you want and also applying filters.

http://commons.apache.org/io/api-1.4/org/apache/commons/io/FileUtils.html

The range function wil give you a list of numbers, while the for loop will iterate through the list and execute the given code for each of its items.

for i in range(5):
      print i

This simply executes print i five times, for i ranging from 0 to 4.

for i in range(5):
      a=i+1

This will execute a=i+1 five times. Since you are overwriting the value of a on each iteration, at the end you will only get the value for the last iteration, that is 4+1.

Run the following commands:

ROBOCOPY C:\source C:\destination /mov /minage:7
del C:\destination /q

Move all the files (using /mov, which moves files and then deletes them as opposed to /move which moves whole filetrees which are then deleted) via robocopy to another location, and then execute a delete command on that path and you're all good.

Also if you have a directory with lots of data in it you can use /mir switch

If you're using Eclipse compiler with lombok, this setup finally worked for me:

• IDEA 14.1
• Lombok plugin
• ... / Compiler / Java Compiler > Use Compiler: Eclipse
• ... / Compiler / Annotation Processors > Enable annotation processing: checked (default configuration)
• ... / Compiler > Additional build process VM options:(Shared build process VM options) -javaagent:lombok.jar

The most important part is the last one, mine looks like following:

Plugin is needed for IntelliJ editor to recognize getters and setters, javaagent is needed for eclipse compiler to compile with lombok.

This is slightly adapted version of Sean's which was preventing back button

// this function makes anchor tags work properly on an iphone

$(document).ready(function(){
if (("standalone" in window.navigator) && window.navigator.standalone) {
  // For iOS Apps
  $("a").on("click", function(e){

    var new_location = $(this).attr("href");
    if (new_location != undefined && new_location.substr(0, 1) != "#" && new_location!='' && $(this).attr("data-method") == undefined){
      e.preventDefault();
      window.location = new_location;
    }
  });
}

});

$("#text").val(function(i,v) { 
   return v.replace(".", ":"); 
});

T = map(lambda i: L[i], Idx)

This worked for me when value came from a TextBox:

string.replace(/\n|\r\n|\r/g, '<br/>');

yum uses RPM, so the following command will list the contents of the installed package:

$ rpm -ql package-name

The easiest way to pass ArrayList using intent

1. Add this line in dependencies block build.gradle.

   implementation 'com.google.code.gson:gson:2.2.4'
   

2. pass arraylist

   ArrayList<String> listPrivate = new ArrayList<>();
   
   
   Intent intent = new Intent(MainActivity.this, ListActivity.class);
   intent.putExtra("private_list", new Gson().toJson(listPrivate));
   startActivity(intent);
   

3. retrieve list in another activity

   ArrayList<String> listPrivate = new ArrayList<>();
   
   Type type = new TypeToken<List<String>>() {
   }.getType();
   listPrivate = new Gson().fromJson(getIntent().getStringExtra("private_list"), type);
   

You can use object also instead of String in type

Works for me..

border-width:0px;
border:none;

Will work fine.

Set alignment: Alignment.centerRight in Container:

Container(

    ),
)

Definitely late to the party; anyway, for those interested, picking up on Lan's mention of HTML5 canvas, you can use gRaphaël Charting which has a MIT License (instead of HighCharts dual license). It's not Bootstrap-specific either, so it's more of a general suggestion.

I have to admit that HighCharts demos seem very pretty, and I have to warn that gRaphaël is quite hard to understand before becoming proficient with it. Anyway you can easily add nice features to your gRaphaël charts (say, tooltips or zooming effects), so it may be worth the effort.

Got this from BrockAllen's answer that worked for me, it displays the keys that have errors:

    var errors =
    from item in ModelState
    where item.Value.Errors.Count > 0
    select item.Key;
    var keys = errors.ToArray();

Source: https://forums.asp.net/t/1805163.aspx?Get+the+Key+value+of+the+Model+error

var newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?foo=bar';
window.history.pushState({path:newurl},'',newurl);

This is how I do this.

DateTime date_time_to_compare = DateTime.Now;
//Compare only date parts
context.YourObject.FirstOrDefault(r =>
                EntityFunctions.TruncateTime(r.date) == EntityFunctions.TruncateTime(date_to_compare));

Try this formula in B2 cell

=IFERROR(INDEX($A$2:$A$7,MATCH(0,COUNTIF(B$1:$B1,$A$2:$A$7),0),1),"")

After click F2 and press Ctrl + Shift + Enter

I just wonder why no one has mentioned Attribute classes as a declarative programming tool in C#. The popular answer of this page has just talked about LINQ as a declarative programming tool.

According to Wikipedia

Common declarative languages include those of database query languages (e.g., SQL, XQuery), regular expressions, logic programming, functional programming, and configuration management systems.

So LINQ, as a functional syntax, is definitely a declarative method, but Attribute classes in C#, as a configuration tool, are declarative too. Here is a good starting point to read more about it: Quick Overview of C# Attribute Programming

here a is an Object but b(null) is not an Object it is a null reference

System.out.println(a instanceof Object); // true

System.out.println(b instanceof Object); // false

here is my similar answer

Be aware that the child selector is not supported in Internet Explorer 6. (If you use the selector in a jQuery/Prototype/YUI etc selector rather than in a style sheet it still works though)

The ES6 way of require is import. You can export your class and import it somewhere else using import { ClassName } from 'path/to/ClassName'syntax.

import fs from 'fs';
export default class Animal {

  constructor(name){
    this.name = name ;
  }

  print(){
    console.log('Name is :'+ this.name);
  }
}

import Animal from 'path/to/Animal.js';

Even if this thread is old is the first on Google, so I'll post an Oracle equivalent to the function implemented here, using regular expressions.

Is fairly faster than nested replace(), and much cleaner.

To replace strings 'a','b','c' with 'd' in a string column from a given table

select regexp_replace(string_col,'a|b|c','d') from given_table

It is nothing else than a regular expression for several static patterns with 'or' operator.

Beware of regexp special characters!

For the react projects with webpack:

1. Do: npm install @babel/plugin-proposal-class-properties --save-dev
2. Create .babelrc (if not present) file in the root folder where package.json and webpack.config.js are present and add below code to that:

{
  "presets": ["@babel/preset-env", "@babel/preset-react"],
  "plugins": [
    [
      "@babel/plugin-proposal-class-properties",
      {
        "loose": true
      }
    ]
  ]
}

3. Add below code to the webpack.config.js file:

{
            test: /\.jsx?$/,
            exclude: /node_modules/,
            loader: 'babel-loader',
            query: {
                presets: ["@babel/preset-env", "@babel/preset-react"]
            },
            resolve: {
                extensions: ['.js', '.jsx']
            }
}

4. Close the terminal and run npm start again.

The TextBox has a property called ReadOnly. If you set that property to true then the TextBox will still be able to scroll but the user wont be able to change the value.

First, it is just a presentation of the float number you see in the debugger. The real value is approximately exact (as much as it's possible).

Note: Use always CultureInfo information when dealing with floating point numbers versus strings.

float.Parse("41.00027357629127",
      System.Globalization.CultureInfo.InvariantCulture);

This is just an example; choose an appropriate culture for your case.

I use <span style="display: inline-block; width: 2ch;">&#9;</span> for a two characters wide tab.

I have created a JSFiddle where I have two nested ng-repeats with tables, and the parent ng-repeat on tbody. If you inspect any row in the table, you will see there are six tbody elements, i.e. the parent level.

( Side note: This fills up the DOM if you have a lot of data on both levels, so I am therefore working on a directive to fetch data and replace, i.e. adding into DOM when clicking parent and removing when another is clicked or same parent again. To get the kind of behavior you find on Prisjakt.nu, if you scroll down to the computers listed and click on the row (not the links). If you do that and inspect elements you will see that a tr is added and then removed if parent is clicked again or another. )

There are a few characters which can indicate a new line. The usual ones are these two: '\n' or '0x0A' (10 in decimal) -> This character is called "Line Feed" (LF). '\r' or '0x0D' (13 in decimal) -> This one is called "Carriage return" (CR).

Different Operating Systems handle newlines in a different way. Here is a short list of the most common ones:

DOS and Windows

They expect a newline to be the combination of two characters, namely '\r\n' (or 13 followed by 10).

Unix (and hence Linux as well)

Unix uses a single '\n' to indicate a new line.

Mac

Macs use a single '\r'.

If you want JUST the source, and not an array with other information:

<?php $url = wp_get_attachment_url( get_post_thumbnail_id($post->ID), 'thumbnail' ); ?>
<img src="<?php echo $url ?>" />

if your div has the runat set to server, you surely can do a myDiv.Visible = false in your Page_PreRender event for example.

if you need help on using the session, have a look in msdn, it's very easy.

In addition to:

myFilePath = replace(myFilePath, "/", "\")
myFilePath = replace(myFilePath, "http:", "")

also replace space:

myFilePath = replace(myFilePath, " ", "%20")

In my case I had to compare column E and I.

I used conditional formatting with new rule. Formula was "=IF($E1<>$I1,1,0)" for highlights in orange and "=IF($E1=$I1,1,0)" to highlight in green.

Next problem is how many columns you want to highlight. If you open Conditional Formatting Rules Manager you can edit for each rule domain of applicability: Check "Applies to"

In my case I used "=$E:$E,$I:$I" for both rules so I highlight only two columns for differences - column I and column E.

As above mentioned, there is no special command to do it. However, if all those connection are inactive, using 'flush tables;' is able to release all those connection which are not active.

If you get the same value for both property and attribute, but still sees it different on the HTML try this to get the HTML one:

$('#inputID').context.defaultValue;

if you don't want to create a UDF in VBA or you can't, this could be an alternative.

=Cell("Filename",A1) this will give you the full file name, and from this you could get the user name with something like this:

=Mid(A1,Find("\",A1,4)+1;Find("\";A1;Find("\";A1;4))-2)

This Formula runs only from a workbook saved earlier.

You must start from 4th position because of the first slash from the drive.

Example to get the last input element:

document.querySelector(".groups-container >div:last-child input")

You can install cygwin, which has rm as well as ls etc.

What you are doing is correct, the problem is somewhere else, e.g. the cookie is being set again somehow on refresh.

you use this code,

var firstValue = "2012-05-12".split('-');
var secondValue = "2014-07-12".split('-');

 var firstDate=new Date();
 firstDate.setFullYear(firstValue[0],(firstValue[1] - 1 ),firstValue[2]);

 var secondDate=new Date();
 secondDate.setFullYear(secondValue[0],(secondValue[1] - 1 ),secondValue[2]);     

  if (firstDate > secondDate)
  {
   alert("First Date  is greater than Second Date");
  }
 else
  {
    alert("Second Date  is greater than First Date");
  }

For Workbench 6.0

Open MySql workbench. To take database backup you need to create New Server Instance(If not available) within Server Administration.

Steps to Create New Server Instance:

1. Select New Server Instance option within Server Administrator.
2. Provide connection details.

After creating new server instance , it will be available in Server Administration list. Double click on Server instance you have created OR Click on Manage Import/Export option and Select Server Instance.

Now, From DATA EXPORT/RESTORE select DATA EXPORT option,Select Schema and Schema Object for backup.

You can take generate backup file in different way as given below-

Q.1) Backup file(.sql) contains both Create Table statements and Insert into Table Statements

ANS:

1. Select Start Export Option

Q.2) Backup file(.sql) contains only Create Table Statements, not Insert into Table statements for all tables

ANS:

1. Select Skip Table Data(no-data) option

2. Select Start Export Option

Q.3) Backup file(.sql) contains only Insert into Table Statements, not Create Table statements for all tables

ANS:

1. Select Advance Option Tab, Within Tables Panel- select no-create info-Do not write CREATE TABLE statement that re-create each dumped table option.
2. Select Start Export Option

For Workbench 6.3

1. Click on Management tab at left side in Navigator Panel
2. Click on Data Export Option
3. Select Schema
4. Select Tables
5. Select required option from dropdown below the tables list as per your requirement
6. Select Include Create schema checkbox
7. Click on Advance option
8. Select Complete insert checkbox in Inserts Panel
9. Start Export

For Workbench 8.0

1. Go to Server tab
2. Go to Database Export

This opens up something like this

3. Select the schema to export in the Tables to export
4. Click on Export to Self-Contained file
5. Check if Advanced Options... are exactly as you want the export
6. Click the button Start Export

This Java code does exactly what is asked in the title of the question, that is "remove newlines from beginning and end of a string-java":

String.replaceAll("^[\n\r]", "").replaceAll("[\n\r]$", "")

Remove newlines only from the end of the line:

String.replaceAll("[\n\r]$", "")

Remove newlines only from the beginning of the line:

String.replaceAll("^[\n\r]", "")

Here are your examples reexplained:

public interface IFood // not Pizza
{
    public void Prepare();

}

public class Pizza : IFood
{
    public void Prepare() // Not order for explanations sake
    {
        //Prepare Pizza
    }
}

public class Burger : IFood
{
    public void Prepare()
    {
        //Prepare Burger
    }
}

Apparently the question poorly describes the OP's problem, but this question is the top search result for dragging to reorder table rows, so that is what I will answer. I wasn't interested in bringing in jQuery UI for something so simple, so here is a jQuery only solution:

$(".grab").mousedown(function(e) {

Note si == 0 and i > 0 ignores the first row, which for me contains TH tags. Replace the alert with your "drag finished" logic.

This answer works in SQL Server 2005, 2008, 2012.

At times the value has MANY single quotes. Rather than add a single quote next to each single quote as described above with 'John''s'. And there are examples using the REPLACE function to handle many single quotes in a value.

Try the following. This is an update statement but you can use it in an INSERT statement as well.

SET QUOTED_IDENTIFIER OFF

DECLARE @s VARCHAR(1000)

SET @s = "SiteId:'1'; Rvc:'6'; Chk:'1832'; TrEmp:'150'; WsId:'81'; TtlDue:'-9.40'; TtlDsc:'0'; TtlSvc:'0'; TtlTax:'-0.88'; TtlPay:'0'; TipAmt:'0.00'; SvcSeq:'09'; ReTx:'N'; TraceId:'160110124347N091832';"


UPDATE TransactionPaymentPrompt
set PromptData = @s

from TransactionPaymentPrompt tpp with (nolock)
where tpp.TransactionID = '106627343'

if you just want diff the specified file, you can :

git diff master 766eceb -- connections/ > 000-mysql-connector.patch

In order to start a service in its own process, you must specify the following in the xml declaration.

<service
  android:name="WordService"
  android:process=":my_process" 
  android:icon="@drawable/icon"
  android:label="@string/service_name"
  >
</service>

In JSX/ React prevent text from wrapping

<div style={{ whiteSpace: "nowrap", overflow: "hidden" }}>
   Text that will never wrap
</div>

You can not test whole abstract class. In this case you have abstract methods, this mean that they should be implemented by class that extend given abstract class.

In that class programmer have to write the source code that is dedicated for logic of his.

In other words there is no sens of testing abstract class because you are not able to check the final behavior of it.

If you have major functionality not related to abstract methods in some abstract class, just create another class where the abstract method will throw some exception.

Create a new directory layout-land, then create xml file with same name in layout-land as it was layout directory and align there your content for Landscape mode.

Note that id of content in both xml is same.

From Bash Reference Manual ? 3.4.2 Special Parameters

#
($#) Expands to the number of positional parameters in decimal.

Therefore, $# will always be either 0 or a bigger integer.

So if you want to do something whenever $# is either 0 or bigger than 1, you just have to check if $# is or is not 1:

[ $# -eq 1 ] && echo "1 positional param" || echo "0 or more than 1"

This uses the syntax:

[ condition ] && {things if true} || {things if false}

Some CSS :

table td, table td * {
    vertical-align: top;
}

Here is my solution:

public static String encode(String key, String data) throws Exception {
  Mac sha256_HMAC = Mac.getInstance("HmacSHA256");
  SecretKeySpec secret_key = new SecretKeySpec(key.getBytes("UTF-8"), "HmacSHA256");
  sha256_HMAC.init(secret_key);

  return Hex.encodeHexString(sha256_HMAC.doFinal(data.getBytes("UTF-8")));
}

public static void main(String [] args) throws Exception {
  System.out.println(encode("key", "The quick brown fox jumps over the lazy dog"));
}

Or you can return the hash encoded in Base64:

Base64.encodeBase64String(sha256_HMAC.doFinal(data.getBytes("UTF-8")));

The output in hex is as expected:

f7bc83f430538424b13298e6aa6fb143ef4d59a14946175997479dbc2d1a3cd8

Go to your cordova project directory then write

npm outdated

npm will be display your outdated plugins, if any plugin outdated then write this command

npm update

AlwaysUp will easily run your batch file as a service. It is similar to FireDaemon (mentioned above) and isn't free, but you may find the rich feature set to be an asset in a professional environment.

Good luck!

I recently leaned about $wpdb->prepare HERE and added into our Free Class Booking plugin, plugin approved on wordpress.org and will live soon:

global $wpdb;
$tablename = $wpdb->prefix . "submitted_form";

$name     = "Kumkum"; //string value use: %s
$email    = "[email protected]"; //string value use: %s
$phone    = "3456734567"; //numeric value use: %d
$country  = "India"; //string value use: %s
$course   = "Database"; //string value use: %s
$message  = "hello i want to read db"; //string value use: %s
$now      = new DateTime(); //string value use: %s
$datesent = $now->format('Y-m-d H:i:s'); //string value use: %s

$sql = $wpdb->prepare("INSERT INTO `$tablename` (`name`, `email`, `phone`, `country`, `course`, `message`, `datesent`) values (%s, %s, %d, %s, %s, %s, %s)", $name, $email, $phone, $country, $course, $message, $datesent);

$wpdb->query($sql);

I use the below query for tracing application activity on a SQL server that does not have trace profiler enabled. The method uses Query Store (SQL Server 2016+) instead of the DMV's. This gives better ability to look into historical data, as well as faster lookups. It is very efficient to capture short-running queries that can't be captured by sp_who/sp_whoisactive.

    Run full script (F5) -> Interact with UI -> Run full script again (F5)

I suggest also checking how much memory is currently being used.

It turns out that the inability to find these DLL files was the first symptom exhibited when trying to run a program (either run or debug) in Visual Studio.

After over a half hour with much head scratching, searching the web, running Process Monitor, and Task Manager, and depends, a completely different program that had been running since the beginning of time reported that "memory is low; try stopping some programs" or some such. After killing Firefox, Thunderbird, Process Monitor, and depends, everything worked again.

i think best approach is to make a common method and call in hover and click events.

There is one more option to follow. In your gradle tasks available in Eclipse, you can set your desired jdk path. (I know this is a while since the question was posted. This answer can help someone.)

Right click on the deploy or any other task and select "Open Gradle Run Configuration..."

Then navigate to "Java Home" and paste your desired java path.

Please note that, bin will be added by the gradle task itself. So don't add the "bin" to the path.

Use Left Outer Join instead of Inner Join to include rows with NULLS.

SELECT Table1.Col1, Table1.Col2, Table1.Col3, Table2.Col4
FROM Table1 LEFT OUTER JOIN 
    Table2 ON Table1.Col1 = Table2.Col1 
    AND Table1.Col2 = Table2.Col2

Assuming your array is sorted (like the one you posted) you could simply iterate over the array and count the longest segment of elements, it's something like @narek.gevorgyan's post but without the awfully big array, and it uses the same amount of memory regardless of the array's size:

private static int getMostPopularElement(int[] a){
    int counter = 0, curr, maxvalue, maxcounter = -1;
    maxvalue = curr = a[0];

    for (int e : a){
        if (curr == e){
            counter++;
        } else {
            if (counter > maxcounter){
                maxcounter = counter;
                maxvalue = curr;
            }
            counter = 0;
            curr = e;
        }
    }
    if (counter > maxcounter){
        maxvalue = curr;
    }

    return maxvalue;
}


public static void main(String[] args) {
    System.out.println(getMostPopularElement(new int[]{1,2,3,4,5,6,7,7,7,7}));
}

If the array is not sorted, sort it with Arrays.sort(a);

Setting android:background and android:button of the RadioButton like the accepted answer didn't work for me. The drawable image was being displayed as a background(eventhough android:button was being set to transparent ) to the radio button text as

android:background="@drawable/radiobuttonstyle"
    android:button="@android:color/transparent"

so gave radiobutton as the custom drawable radiobuttonstyle.xml

<RadioButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="true"
    android:text="Maintenance"
    android:id="@+id/radioButton1"
    android:button="@drawable/radiobuttonstyle"
      />

and radiobuttonstyle.xml is as follows

<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_checked="true" android:drawable="@drawable/ic_radio_checked"></item>
  <item android:state_checked="false" android:drawable="@drawable/ic_radio_unchecked"></item>
</selector>

and after this radiobutton with custom button style worked.

The following does not return a response:

You must return anything like return afunction() or return 'a string'.

This can solve the issue

In the same spirit as 4ndrew's answer:

listOfNames="RA
RB
R C
RD"

# To allow for other whitespace in the string:
# 1. add double quotes around the list variable, or
# 2. see the IFS note (under 'Side Notes')

for databaseName in "$listOfNames"   #  <-- Note: Added "" quotes.
do
  echo "$databaseName"  # (i.e. do action / processing of $databaseName here...)
done

# Outputs
# RA
# RB
# R C
# RD

B. No whitespace in the names:

listOfNames="RA
RB
R C
RD"

for databaseName in $listOfNames  # Note: No quotes
do
  echo "$databaseName"  # (i.e. do action / processing of $databaseName here...)
done

# Outputs
# RA
# RB
# R
# C
# RD

Notes

1. In the second example, using listOfNames="RA RB R C RD" has the same output.

Other ways to bring in data include:

• stdin (listed below),
• variables,
• an array (the accepted answer),
• a file...

Read from stdin

# line delimited (each databaseName is stored on a line)
while read databaseName
do
  echo "$databaseName"  # i.e. do action / processing of $databaseName here...
done # <<< or_another_input_method_here

2. the bash IFS "field separator to line" [1] delimiter can be specified in the script to allow other whitespace (i.e. IFS='\n', or for MacOS IFS='\r')
3. I like the accepted answer also :) -- I've include these snippets as other helpful ways that also answer the question.
4. Including #!/bin/bash at the top of the script file indicates the execution environment.
5. It took me months to figure out how to code this simply :)

Other Sources (while read loop)

You can declare as many Exceptions as you want for your interface method. But the class you gave in your question is invalid. It should read

public class MyClass implements MyInterface {
  public void find(int x) throws A_Exception, B_Exception{
    ----
    ----
    ---
  }
}

Then an interface would look like this

public interface MyInterface {
  void find(int x) throws A_Exception, B_Exception;
}

Note that getcwd(3) is also available in Microsoft's libc: getcwd(3), and works the same way you'd expect.

Must link with -loldnames (oldnames.lib, which is done automatically in most cases), or use _getcwd(). The unprefixed version is unavailable under Windows RT.

To avoid using integer values to identify the VideoCapture properties, one can use, e.g., cv2.cv.CV_CAP_PROP_FPS in OpenCV 2.4 and cv2.CAP_PROP_FPS in OpenCV 3.0. (See also Stefan's comment below.)

Here a utility function that works for both OpenCV 2.4 and 3.0:

# returns OpenCV VideoCapture property id given, e.g., "FPS"
def capPropId(prop):
  return getattr(cv2 if OPCV3 else cv2.cv,
    ("" if OPCV3 else "CV_") + "CAP_PROP_" + prop)

OPCV3 is set earlier in my utilities code like this:

from pkg_resources import parse_version
OPCV3 = parse_version(cv2.__version__) >= parse_version('3')

The problem is that you are trying to access the element before it exists. You need to wait for the page to be fully loaded. A possible approach is to use the onload handler:

window.onload = function () {
    var e = document.getElementById("db_info");
    e.innerHTML='Found you';
};

Most common JavaScript libraries provide a DOM-ready event, though. This is better, since window.onload waits for all images, too. You do not need that in most cases.

Another approach is to place the script tag right before your closing </body>-tag, since everything in front of it is loaded at the time of execution, then.

Looks like Calendar is the new way to go:

Calendar mydate = Calendar.getInstance();
mydate.setTimeInMillis(timestamp*1000);
out.println(mydate.get(Calendar.DAY_OF_MONTH)+"."+mydate.get(Calendar.MONTH)+"."+mydate.get(Calendar.YEAR));

The last line is just an example how to use it, this one would print eg "14.06.2012".

If you have used System.currentTimeMillis() to save the Timestamp you don't need the "*1000" part.

If you have the timestamp in a string you need to parse it first as a long: Long.parseLong(timestamp).

https://docs.oracle.com/javase/7/docs/api/java/util/Calendar.html

Just a hint... think twice before using "transform: rotate()", or even "-ms-transform :rotate()" (IE9) with mobiles!

I've been knocking hard to the wall for days. I have a 'kinetic' system going on, that slides images and, on top of it, a command area. I did "transform" on an arrow button so it simulates pointing up and down... I've reviewd the 1.000 plus code lines for ages!!! ;-)

All ok, once I removed transform:rotate from the CSS. It's a bit (not to use bad words) tricky the way IE handles it, comparing to other borwsers.

Great answer @Spudley! Thanks for writing it!

I needed to print important warning about skipped tests exactly when PyTest muted literally everything.

I didn't want to fail a test to send a signal, so I did a hack as follow:

def test_2_YellAboutBrokenAndMutedTests():
    import atexit
    def report():
        print C_patch.tidy_text("""
In silent mode PyTest breaks low level stream structure I work with, so
I cannot test if my functionality work fine. I skipped corresponding tests.
Run `py.test -s` to make sure everything is tested.""")
    if sys.stdout != sys.__stdout__:
        atexit.register(report)

The atexit module allows me to print stuff after PyTest released the output streams. The output looks as follow:

============================= test session starts ==============================
platform linux2 -- Python 2.7.3, pytest-2.9.2, py-1.4.31, pluggy-0.3.1

~/.../sources/C_patch$

Message is printed even when PyTest is in silent mode, and is not printed if you run stuff with py.test -s, so everything is tested nicely already.

I make a variation to generate this out from script:

volume C: - 49 GB total space / 29512314880 byte(s) free

I use diskpart to get this information.

@echo off

if "%1" == "" goto :usage
set drive=%1
set drive=%drive:\=%
set drive=%drive::=%

Print a string as hex bytes?

The accepted answer gives:

s = "Hello world !!"
":".join("{:02x}".format(ord(c)) for c in s)

returns:

'48:65:6c:6c:6f:20:77:6f:72:6c:64:20:21:21'

The accepted answer works only so long as you use bytes (mostly ascii characters). But if you use unicode, e.g.:

a_string = u"?????? ???!!" # "Prevyet mir", or "Hello World" in Russian.

You need to convert to bytes somehow.

If your terminal doesn't accept these characters, you can decode from UTF-8 or use the names (so you can paste and run the code along with me):

a_string = (
    "\N{CYRILLIC CAPITAL LETTER PE}"
    "\N{CYRILLIC SMALL LETTER ER}"
    "\N{CYRILLIC SMALL LETTER I}"
    "\N{CYRILLIC SMALL LETTER VE}"
    "\N{CYRILLIC SMALL LETTER IE}"
    "\N{CYRILLIC SMALL LETTER TE}"
    "\N{SPACE}"
    "\N{CYRILLIC SMALL LETTER EM}"
    "\N{CYRILLIC SMALL LETTER I}"
    "\N{CYRILLIC SMALL LETTER ER}"
    "\N{EXCLAMATION MARK}"
    "\N{EXCLAMATION MARK}"
)

So we see that:

":".join("{:02x}".format(ord(c)) for c in a_string)

returns

'41f:440:438:432:435:442:20:43c:438:440:21:21'

a poor/unexpected result - these are the code points that combine to make the graphemes we see in Unicode, from the Unicode Consortium - representing languages all over the world. This is not how we actually store this information so it can be interpreted by other sources, though.

To allow another source to use this data, we would usually need to convert to UTF-8 encoding, for example, to save this string in bytes to disk or to publish to html. So we need that encoding to convert the code points to the code units of UTF-8 - in Python 3, ord is not needed because bytes are iterables of integers:

>>> ":".join("{:02x}".format(c) for c in a_string.encode('utf-8'))
'd0:9f:d1:80:d0:b8:d0:b2:d0:b5:d1:82:20:d0:bc:d0:b8:d1:80:21:21'

Or perhaps more elegantly, using the new f-strings (only available in Python 3):

>>> ":".join(f'{c:02x}' for c in a_string.encode('utf-8'))
'd0:9f:d1:80:d0:b8:d0:b2:d0:b5:d1:82:20:d0:bc:d0:b8:d1:80:21:21'

In Python 2, pass c to ord first, i.e. ord(c) - more examples:

>>> ":".join("{:02x}".format(ord(c)) for c in a_string.encode('utf-8'))
'd0:9f:d1:80:d0:b8:d0:b2:d0:b5:d1:82:20:d0:bc:d0:b8:d1:80:21:21'
>>> ":".join(format(ord(c), '02x') for c in a_string.encode('utf-8'))
'd0:9f:d1:80:d0:b8:d0:b2:d0:b5:d1:82:20:d0:bc:d0:b8:d1:80:21:21'

Update:

Django 2.2 version now has a bulk_update.

Old answer:

Refer to the following django documentation section

Updating multiple objects at once

In short you should be able to use:

ModelClass.objects.filter(name='bar').update(name="foo")

You can also use F objects to do things like incrementing rows:

from django.db.models import F
Entry.objects.all().update(n_pingbacks=F('n_pingbacks') + 1)

See the documentation.

However, note that:

• This won't use ModelClass.save method (so if you have some logic inside it won't be triggered).
• No django signals will be emitted.
• You can't perform an .update() on a sliced QuerySet, it must be on an original QuerySet so you'll need to lean on the .filter() and .exclude() methods.

Commenting here as this seems to be the most popular answer on the subject for searching for files whilst excluding certain directories in powershell.

To avoid issues with post filtering of results (i.e. avoiding permission issues etc), I only needed to filter out top level directories and that is all this example is based on, so whilst this example doesn't filter child directory names, it could very easily be made recursive to support this, if you were so inclined.

Quick breakdown of how the snippet works

$folders << Uses Get-Childitem to query the file system and perform folder exclusion

$file << The pattern of the file I am looking for

foreach << Iterates the $folders variable performing a recursive search using the Get-Childitem command

$folders = Get-ChildItem -Path C:\ -Directory -Name -Exclude Folder1,"Folder 2"
$file = "*filenametosearchfor*.extension"

foreach ($folder in $folders) {
   Get-Childitem -Path "C:/$folder" -Recurse -Filter $file | ForEach-Object { Write-Output $_.FullName }
}

Bergi's solution works nicely when fs is promise based. You can use bluebird, fs-extra or fs-promise for this.

However, solution for node's native fs libary is as follows:

const result = await Promise.all(filePaths
    .map( async filePath => {
      const fileContents = await getAssetFromCache(filePath, async function() {

        // 1. Wrap with Promise    
        // 2. Return the result of the Promise
        return await new Promise((res, rej) => {

Instead of using a sheet name, in case you don't know or can't open the excel file to check in ubuntu (in my case, Python 3.6.7, ubuntu 18.04), I use the parameter index_col (index_col=0 for the first sheet)

import pandas as pd
file_name = 'some_data_file.xlsx' 
df = pd.read_excel(file_name, index_col=0)
print(df.head()) # print the first 5 rows

You could just use

DataGridView1.CurrentRow.Cells["ColumnName"].Value

Use List.AddRange(collection As IEnumerable(Of T)) method.

It allows you to append at the end of your list another collection/list.

Example:

List<string> initialList = new List<string>();
// Put whatever you want in the initial list
List<string> listToAdd = new List<string>();
// Put whatever you want in the second list
initialList.AddRange(listToAdd);

you can fix this problem with style like this.

<div class="card"><img alt="Card image cap" class="card-img-top img-fluid" src="img/butterPecan.jpg" style="width: 18rem; height: 20rem;" />

This is my solution with prepared statements and stored procedure is returning several rows not only one value.

<?php

require 'config.php';
header('Content-type:application/json');
$connection->set_charset('utf8');

$mIds = $_GET['ids'];

$stmt = $connection->prepare("CALL sp_takes_string_returns_table(?)");
$stmt->bind_param("s", $mIds);

$stmt->execute();

$result = $stmt->get_result();
$response = $result->fetch_all(MYSQLI_ASSOC);
echo json_encode($response);

$stmt->close();
$connection->close();

The simple way to use XMLHttpRequest with pure JavaScript. You can set custom header but it's optional used based on requirement.

1. Using POST Method:

window.onload = function(){
    var request = new XMLHttpRequest();
    var params = "UID=CORS&name=CORS";

    request.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {
            console.log(this.responseText);
        }
    };

    request.open('POST', 'https://www.example.com/api/createUser', true);
    request.setRequestHeader('api-key', 'your-api-key');
    request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    request.send(params);
}

You can send params using POST method.

2. Using GET Method:

Please run below example and will get an JSON response.

window.onload = function(){_x000D_
    var request = new XMLHttpRequest();_x000D_
_x000D_
    request.onreadystatechange = function() {_x000D_
        if (this.readyState == 4 && this.status == 200) {_x000D_
            console.log(this.responseText);_x000D_
        }_x000D_
    };_x000D_
_x000D_
    request.open('GET', 'https://jsonplaceholder.typicode.com/users/1');_x000D_
    request.send();_x000D_
}

Try this:

static double Evaluate(string expression) {
  var loDataTable = new DataTable();
  var loDataColumn = new DataColumn("Eval", typeof (double), expression);
  loDataTable.Columns.Add(loDataColumn);
  loDataTable.Rows.Add(0);
  return (double) (loDataTable.Rows[0]["Eval"]);
}

mayby one little change from the top answer, because DB_NAME() returns always content db of execution. so, for me better like below:

sp_MSforeachdb 'select DB_name(db_id(''?'')) as DB, * From ?..sysobjects where xtype in (''U'', ''P'') And name like ''[_]x[_]%'''

In my case I was looking for tables their names started with _x_

Cheers, Ondrej

This line is the problem:

int estimatedPopulation (int currentPopulation,
                         float growthRate (birthRate, deathRate))

Make it:

int estimatedPopulation (int currentPopulation, float birthRate, float deathRate)

instead and invoke the function with three arguments like

estimatePopulation( currentPopulation, birthRate, deathRate );

OR declare it with two arguments like:

int estimatedPopulation (int currentPopulation, float growthrt ) { ... }

and call it as

estimatedPopulation( currentPopulation, growthRate (birthRate, deathRate));

Edit:

Probably more important here - C++ (and C) names have scope. You can have two things named the same but not at the same time. In your particular case your grouthRate variable in the main() hides the function with the same name. So within main() you can only access grouthRate as float. On the other hand, outside of the main() you can only access that name as a function, since that automatic variable is only visible within the scope of main().

Just hope I didn't confuse you further :)

select field1, field2, 'example' as TempField
from table1

This should work across different SQL implementations.

It makes a difference if you return early:

try:
    run_code1()
except TypeError:
    run_code2()
    return None   # The finally block is run before the method returns
finally:
    other_code()

Compare to this:

try:
    run_code1()
except TypeError:
    run_code2()
    return None   

other_code()  # This doesn't get run if there's an exception.

Other situations that can cause differences:

• If an exception is thrown inside the except block.
• If an exception is thrown in run_code1() but it's not a TypeError.
• Other control flow statements such as continue and break statements.

You should implement Comparable <Person>. Assuming all fields will not be null (for simplicity sake), that age is an int, and compare ranking is first, last, age, the compareTo method is quite simple:

public int compareTo(Person other) {
    int i = firstName.compareTo(other.firstName);
    if (i != 0) return i;

    i = lastName.compareTo(other.lastName);
    if (i != 0) return i;

    return Integer.compare(age, other.age);
}

Another possibility could be this:

var concat = String(5) + String(6);

follow some steps below:

1. open cygwin setup again

2. choose catagory on view tab

3. fill "make" in search tab

4. expand devel

5. find "make: a GNU version of the 'make' ultility", click to install

6. Done!

This is another solution as well

PackageManager pm = context.getPackageManager();
int hasPerm = pm.checkPermission(
    android.Manifest.permission.WRITE_EXTERNAL_STORAGE, 
    context.getPackageName());
if (hasPerm != PackageManager.PERMISSION_GRANTED) {
   // do stuff
}

You're looking for JSON.stringify().

Inside - Outside

• gravity arranges the content inside the view.
• layout_gravity arranges the view's position outside of itself.

Sometimes it helps to see a picture, too. The green and blue are TextViews and the other two background colors are LinearLayouts.

Notes

• The layout_gravity does not work for views in a RelativeLayout. Use it for views in a LinearLayout or FrameLayout. See my supplemental answer for more details.
• The view's width (or height) has to be greater than its content. Otherwise gravity won't have any effect. Thus, wrap_content and gravity are meaningless together.
• The view's width (or height) has to be less than the parent. Otherwise layout_gravity won't have any effect. Thus, match_parent and layout_gravity are meaningless together.
• The layout_gravity=center looks the same as layout_gravity=center_horizontal here because they are in a vertical linear layout. You can't center vertically in this case, so layout_gravity=center only centers horizontally.
• This answer only dealt with setting gravity and layout_gravity on the views within a layout. To see what happens when you set the gravity of the of the parent layout itself, check out the supplemental answer that I referred to above. (Summary: gravity doesn't work well on a RelativeLayout but can be useful with a LinearLayout.)

So remember, layout_gravity arranges a view in its layout. Gravity arranges the content inside the view.

Using Node.js

sync mode:

var fs = require("fs");
var text = fs.readFileSync("./mytext.txt");
var textByLine = text.split("\n")

async mode:

var fs = require("fs");
fs.readFile("./mytext.txt", function(text){
    var textByLine = text.split("\n")
});

UPDATE

As of at least Node 6, readFileSync returns a Buffer, so it must first be converted to a string in order for split to work:

var text = fs.readFileSync("./mytext.txt").toString('utf-8');

Or

var text = fs.readFileSync("./mytext.txt", "utf-8");

You can use JSTL tags together with EL expressions to avoid intermixing Java and HTML code:

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>

        <c:out value="${param.name}" />
        // and so on

    </body>
</html>

SELECT is_read_committed_snapshot_on FROM sys.databases 
WHERE name= 'YourDatabase'

Return value:

• 1: READ_COMMITTED_SNAPSHOT option is ON. Read operations under the READ COMMITTED isolation level are based on snapshot scans and do not acquire locks.
• 0 (default): READ_COMMITTED_SNAPSHOT option is OFF. Read operations under the READ COMMITTED isolation level use Shared (S) locks.

If you want to use parameters for a,b,c,d in Laravel 4

Model::where(function ($query) use ($a,$b) {
    $query->where('a', '=', $a)

})
->where(function ($query) use ($c,$d) {
    $query->where('c', '=', $c)
          ->orWhere('d', '=', $d);
});

You have to change from wb to w:

def __init__(self):
    self.myCsv = csv.writer(open('Item.csv', 'wb')) 
    self.myCsv.writerow(['title', 'link'])

to

def __init__(self):
    self.myCsv = csv.writer(open('Item.csv', 'w'))
    self.myCsv.writerow(['title', 'link'])

After changing this, the error disappears, but you can't write to the file (in my case). So after all, I don't have an answer?

Changing to 'rb' brings me the other error: io.UnsupportedOperation: write

A solution for me:

$old_ErrorActionPreference = $ErrorActionPreference
$ErrorActionPreference = 'SilentlyContinue'
if((Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue) -eq $null) {
   WriteTraceForTrans "The session configuration MyShellUri is already unregistered."
}
else {        
   #Unregister-PSSessionConfiguration -Name "MyShellUri" -Force -ErrorAction Ignore

Closing IIS Express

By default Visual Studio places the IISExpress icon in your system tray at the lower right hand side of your screen, by the clock. You can right click it and choose exit. If you don't see the icon, try clicking the small arrow to view the full list of icons in the system tray.

then right click and choose Exit:

Changing the Port

Another option is to change the port by modifying the project properties. You'll need to do this for each web project in your solution.

1. Visual Studio > Solution Explorer
2. Right click the web project and choose Properties
3. Go to the Web tab
4. In the 'Servers' section, change the port in the Project URL box
5. Repeat for each web project in the solution

If All Else Fails

If that doesn't work, you can try to bring up Task Manager and close the IIS Express System Tray (32 bit) process and IIS Express Worker Process (32 bit).

If it still doesn't work, as ni5ni6 pointed out, there is a 'Web Deployment Agent Service' running on the port 80. Use this article to track down which process uses it, and turn it off:

HTTP VS HTTPS PERFORMANCE COMPARISON

I have always associated HTTPS with slower page load times when compared to plain old HTTP. As a web developer, web page performance is important to me and anything that will slow down the performance of my web pages is a no-no.

In order to understand the performance implications involved, the diagram below gives you a basic idea of what happens under the hood when you make a request for a resource using HTTPS.

As you can see from the diagram above, there are a few extra steps that need to take place when using HTTPS compared to using plain HTTP. When you make a request using HTTPS, a handshake needs to occur in order to verify the authenticity of the request. This handshake is an extra step when compared to an HTTP request and does unfortunately incur some overhead.

In order to understand the performance implications and see for myself whether or not the performance impact would be significant, I used this site as a testing platform. I headed over to webpagetest.org and used the visual comparison tool to compare this site loading using HTTPS vs HTTP.

As you can see from Here is Test video Result using HTTPS did have an impact on my page load times, however the difference is negligible and I only noticed a 300 millisecond difference. It's important to note that these times depend on many factors, such as computer performance, connection speed, server load, and distance from server.

Your site may be different, and it is important to test your site thoroughly and check the performance impact involved in switching to HTTPS.

jQuery("#autoship_option option:first").attr('selected', true);

The opposite of .append() is .prepend().

From the jQuery documentation for prepend…

The .prepend() method inserts the specified content as the first child of each element in the jQuery collection (To insert it as the last child, use .append()).

I realize this doesn’t answer the OP’s specific case. But it does answer the question heading. :) And it’s the first hit on Google for “jquery opposite append”.

You can also use stack()

df= DataFrame([list(range(5))], columns = [“a{}”.format(I) for I in range(5)])

After u run df, then run:

df.stack()

You obtain your dataframe in series

The solution is using of the following JVM argument:

-Dlog4j.configuration={path to file}

If the file is NOT in the classpath (in WEB-INF/classes in case of Tomcat) but somewhere on you disk, use file:, like

-Dlog4j.configuration=file:C:\Users\me\log4j.xml

More information and examples here: http://logging.apache.org/log4j/1.2/manual.html

You have just created an empty integer array. The array guess does not contain anything to my knowledge. The rest you should work out to get better.

The beauty of jQuery would allow us to do the following:

$(function()
{
    var benefits = $('#benefits');

    // this is the show function
    $('a[name=1]').click(function()
    { 
        benefits.show();
    });

    // this is the hide function
    $('a', benefits).click(function()
    {
        benefits.hide();
    });
});

Alternatively you could have 1 button toggle the display, like this:

$(function()
{
    // this is the show and hide function, all in 1!
    $('a[name=1]').click(function()
    { 
        $('#benefits').toggle();
    });
});

I am not familiar with Axios, but as far as I know in javascript and ajax there is an option

withCredentials: true

This will automatically send the cookie to the client-side. As an example, this scenario is also generated with passportjs, which sets a cookie on the server

you should try this

~/Views/Shared/parts/UMFview.ascx

place the ~/Views/ before your code

C:\Documents and Settings\Scripter>echo %cd%
C:\Documents and Settings\Scripter

C:\Documents and Settings\Scripter>

for Unix use pwd command

Current working directory

I'm sure there's some nice library that does this sort of thing already for you... But to just stick with the approach you're already going with, Map#entrySet gives you a combined Object with the key and the value. So something like:

for (Map.Entry<String, Object> entry : map.entrySet()) {
    System.out.println(entry.getKey() + ":" + entry.getValue().toString());
}

will do what you're after.

If you're using java 8, there's also the new streaming approach.

map.forEach((key, value) -> System.out.println(key + ":" + value));

Getting location updates requires lots of bolierplate code in Android, You need to take care of

• Google Play services availablity Check,
• Update Google play Service if it is old or not available
• Dialog Creation of GoogleApiClient and its callbacks connected,disconnected etc.
• Stopping and releasing resources for location updates
• Handling Location permission scenarios
• Checking Location services are On or Off
• Getting lastknown location is not so easy either
• Fallback to last known location if not getting location after certain duration

To ease out all these steps i have created Android-EasyLocation (small android library) which will take care all this stuff and you can focus on business logic.

All you need is extend EasyLocationActivity and this

requestSingleLocationFix(easyLocationRequest);

or

requestLocationUpdates(easyLocationRequest);

Checkout sample app and steps needed here at https://github.com/akhgupta/Android-EasyLocation

You can use strtotime() as in Gazler's example, which is great for this case.

If you need more complicated control use mktime().

$end_date = mktime(date("H"), date("i"), date("s"), date("n") + 1, date("j"), date("Y"));

In more complicated build scenarios, it is common to break compilation into stages, with compilation and assembly happening first (output to object files), and linking object files into a final executable or library afterward--this prevents having to recompile all object files when their source files haven't changed. That's why including the linking flag -lm isn't working when you put it in CFLAGS (CFLAGS is used in the compilation stage).

The convention for libraries to be linked is to place them in either LOADLIBES or LDLIBS (GNU make includes both, but your mileage may vary):

LDLIBS=-lm

This should allow you to continue using the built-in rules rather than having to write your own linking rule. For other makes, there should be a flag to output built-in rules (for GNU make, this is -p). If your version of make does not have a built-in rule for linking (or if it does not have a placeholder for -l directives), you'll need to write your own:

client.o: client.c
    $(CC) $(CFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c -o $@ $<

client: client.o
    $(CC) $(LDFLAGS) $(TARGET_ARCH) $^ $(LOADLIBES) $(LDLIBS) -o $@

Let's say I have an array arr. When would the following not give the number of elements of the array: sizeof(arr) / sizeof(arr[0])?

One thing I've often seen new programmers doing this:

void f(Sample *arr)
{
   int count = sizeof(arr)/sizeof(arr[0]); //what would be count? 10?
}

Sample arr[10];
f(arr);

So new programmers think the value of count will be 10. But that's wrong.

Even this is wrong:

void g(Sample arr[]) //even more deceptive form!
{
   int count = sizeof(arr)/sizeof(arr[0]); //count would not be 10  
}

It's all because once you pass an array to any of these functions, it becomes pointer type, and so sizeof(arr) would give the size of pointer, not array!

EDIT:

The following is an elegant way you can pass an array to a function, without letting it to decay into pointer type:

template<size_t N>
void h(Sample (&arr)[N])
{
    size_t count = N; //N is 10, so would be count!
    //you can even do this now:
    //size_t count = sizeof(arr)/sizeof(arr[0]);  it'll return 10!
}
Sample arr[10];
h(arr); //pass : same as before!

An empty static class is appropriate. Consider using several classes, so that you end up with good groups of related constants, and not one giant Globals.cs file.

Additionally, for some int constants, consider the notation:

[Flags]
enum Foo
{
}

As this allows for treating the values like flags.

each_with_object is probably the cleanest way to go here:

new_items = items.each_with_object([]) do |x, memo|
    ret = process_x(x)
    memo << ret unless ret.nil?
end

In my opinion, each_with_object is better than inject/reduce in conditional cases because you don't have to worry about the return value of the block.

These are listed in RFC3986. See the Collected ABNF for URI to see what is allowed where and the regex for parsing/validation.

this code will give you latest post first, i think this answer is helpful.

    mInstaList=(RecyclerView)findViewById(R.id.insta_list);
    mInstaList.setHasFixedSize(true);

    LinearLayoutManager layoutManager = new LinearLayoutManager(this);
    layoutManager.setOrientation(LinearLayoutManager.VERTICAL);

    mInstaList.setLayoutManager(layoutManager);
    layoutManager.setStackFromEnd(true);
    layoutManager.setReverseLayout(true);

if you want to find mode as int Value here is the easiest way I was trying to find out mode of Array using Scipy Stats but the problem is that output of the code look like:

ModeResult(mode=array(2), count=array([[1, 2, 2, 2, 1, 2]])) , I only want the Integer output so if you want the same just try this

import numpy as np
from scipy import stats
numbers = list(map(int, input().split())) 
print(int(stats.mode(numbers)[0]))

Last line is enough to print Mode Value in Python: print(int(stats.mode(numbers)[0]))

What finally cleared this up for me was a comment showing that:

git checkout main
git merge --squash feature

is the equivalent of doing:

git checkout feature
git diff main > feature.patch
git checkout main
patch -p1 < feature.patch
git add .

When I want to merge a feature branch with 105(!!) commits and have them all squashed into one, I don't want to git rebase -i origin/master because I need to separately resolve merge conflicts for each of the intermediate commits (or at least the ones which git can't figure out itself). Using git merge --squash gets me the result I want, of a single commit for merging an entire feature branch. And, I only need to do at most one manual conflict resolution.

The easiest way to do this is to delete the branch remotely and then use:

git fetch --prune (aka git fetch -p)

In case somebody is still looking for dynamic function call with dynamic parameters -

callFunction("aaa('hello', 'world')");

    function callFunction(func) {
                try
                {
                    eval(func);
                }
                catch (e)
                { }
            }
    function aaa(a, b) {
                alert(a + ' ' + b);
            }

Usage

File outDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).toString());
copyAssets("fold",outDir.toString());

In to the external directory find all files and directories that are within the fold assets

use the .not() method and check for an attribute:

myList.Count is a method on the list object, it just returns the value of a field so is very fast. As it is a small method it is very likely to be inlined by the compiler (or runtime), they may then allow other optimization to be done by the compiler.

myList.Count() is calling an extension method (introduced by LINQ) that loops over all the items in an IEnumerable, so should be a lot slower.

However (In the Microsoft implementation) the Count extension method has a “special case” for Lists that allows it to use the list’s Count property, this means the Count() method is only a little slower than the Count property.

It is unlikely you will be able to tell the difference in speed in most applications.

So if you know you are dealing with a List use the Count property, otherwise if you have a "unknown" IEnumerabl, use the Count() method and let it optimise for you.

You can use virtualenvwrapper in order to ease the way you work with virtualenv.

Installing virtualenvwrapper:

pip install virtualenvwrapper

If you are using a standard shell, open your ~/.bashrc or ~/.zshrc if you use Oh My Zsh. Add these two lines:

export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh

To activate an existing virtualenv, use command workon:

$ workon myenv
(myenv)$

In order to deactivate your virtualenv:

(myenv)$ deactivate

Here is my tutorial, step by step on how to install virtualenv and virtualenvwrapper.

explain select * from test where id in (values (1), (2));

QUERY PLAN

 Seq Scan on test  (cost=0.00..1.38 rows=2 width=208)
   Filter: (id = ANY ('{1,2}'::bigint[]))

But if try 2nd query:

explain select * from test where id = any (values (1), (2));

QUERY PLAN

Hash Semi Join  (cost=0.05..1.45 rows=2 width=208)
       Hash Cond: (test.id = "*VALUES*".column1)
       ->  Seq Scan on test  (cost=0.00..1.30 rows=30 width=208)
       ->  Hash  (cost=0.03..0.03 rows=2 width=4)
             ->  Values Scan on "*VALUES*"  (cost=0.00..0.03 rows=2 width=4)

We can see that postgres build temp table and join with it

That's because that's an SQL function, not PHP. You can use PDO::lastInsertId().

Like:

$stmt = $db->prepare("...");
$stmt->execute();
$id = $db->lastInsertId();

If you want to do it with SQL instead of the PDO API, you would do it like a normal select query:

$stmt = $db->query("SELECT LAST_INSERT_ID()");
$lastId = $stmt->fetchColumn();

I could do that following the steps:

1. Create a folder __mocks__/ (as pointed by @Januartha comment)
2. Implement an axios.js mock file
3. Use my implemented module on test

The mock will happen automatically

Example of the mock module:

module.exports = {
    get: jest.fn((url) => {
        if (url === '/something') {
            return Promise.resolve({
                data: 'data'
            });
        }
    }),
    post: jest.fn((url) => {
        if (url === '/something') {
            return Promise.resolve({
                data: 'data'
            });
        }
        if (url === '/something2') {
            return Promise.resolve({
                data: 'data2'
            });
        }
    }),
    create: jest.fn(function () {
        return this;
    })
};

You can use INSERT...SELECT syntax. Note that you can quote '1' directly in the SELECT part.

Once you're logged into phpmyadmin look on the top navigation for "Settings" and click that then:

Unfortunately changing it through the UI means that the changes don't persist between logins.

Just to complete the answer, If you are using the LINQ syntax, you can just wrap it since it returns an IEnumerable:

(from int x in intList
 where x > 5
 select x * 2).FirstOrDefault()

I had same issue. Resolved by firstly setting :

imageView.setMinHeight(0);
imageView.setMinimumHeight(0);

And then :

imageView.getLayoutParams().height= ViewGroup.LayoutParams.MATCH_PARENT;

setMinHeight is defined by ImageView, while setMinimumHeight is defined by View. According to the docs, the greater of the two values is used, so both must be set.

Source code

The bug is probably somewhere else in your code, because it should work fine:

>>> 3 not in [2, 3, 4]
False
>>> 3 not in [4, 5, 6]
True

Or with tuples:

>>> (2, 3) not in [(2, 3), (5, 6), (9, 1)]
False
>>> (2, 3) not in [(2, 7), (7, 3), "hi"]
True

paste this at your body tag!

this will remove the top margin

You can use sp_executesql with output parameter.

declare @S nvarchar(max) = 'select @x = 1'

declare @xx int
set @xx = 0

exec sp_executesql @S, N'@x int out', @xx out

select @xx

Result:

(No column name)
1

Edit

In my sample @S is instead of your @template. As you can see I assign a value to @x so you need to modify @template so it internally assigns the comma separated string to the variable you define in your second argument to sp_executesql. In my sample N'@x int out'. You probably want a varchar(max) output parameter. Something like N'@Result varchar(max) out'

Here is another example building a comma separated string from master..spt_values

declare @template nvarchar(max)
set @template = 
'select @Result += cast(number as varchar(10))+'',''
from master..spt_values
where type = ''P''
'

declare @CommaString varchar(max)
set @CommaString = ''

exec sp_executesql @template, N'@Result varchar(max) out', @CommaString out

select @CommaString

The following worked for me:

1. Go to the top right corner of IntelliJ -> click the icon
2. In the Project Structure window -> Select project -> In the Project SDK, choose the correct version -> Click Apply -> Click Okay

You can also use glob for this:

$dirname = "media/images/iconized/";
$images = glob($dirname."*.png");

foreach($images as $image) {
    echo '<img src="'.$image.'" /><br />';
}

You can use percent values:
