You can handle the ListView's PreviewMouseLeftButtonUp event. The reason not to handle the PreviewMouseLeftButtonDown event is that, by the time when you handle the event, the ListView's SelectedItem may still be null.

XAML:

<ListView ... PreviewMouseLeftButtonUp="listView_Click"> ...

Code behind:

private void listView_Click(object sender, RoutedEventArgs e)
{
    var item = (sender as ListView).SelectedItem;
    if (item != null)
    {
        ...
    }
}

Olof's answer is good, but it needs one more thing before it's perfect. In the comments below his answer, dacwe (correctly) points out that his implementation violates the Compare/Equals contract for Sets. If you try to call contains or remove on an entry that's clearly in the set, the set won't recognize it because of the code that allows entries with equal values to be placed in the set. So, in order to fix this, we need to test for equality between the keys:

static <K,V extends Comparable<? super V>> SortedSet<Map.Entry<K,V>> entriesSortedByValues(Map<K,V> map) {
    SortedSet<Map.Entry<K,V>> sortedEntries = new TreeSet<Map.Entry<K,V>>(
        new Comparator<Map.Entry<K,V>>() {
            @Override public int compare(Map.Entry<K,V> e1, Map.Entry<K,V> e2) {
                int res = e1.getValue().compareTo(e2.getValue());
                if (e1.getKey().equals(e2.getKey())) {
                    return res; // Code will now handle equality properly
                } else {
                    return res != 0 ? res : 1; // While still adding all entries
                }
            }
        }
    );
    sortedEntries.addAll(map.entrySet());
    return sortedEntries;
}

"Note that the ordering maintained by a sorted set (whether or not an explicit comparator is provided) must be consistent with equals if the sorted set is to correctly implement the Set interface... the Set interface is defined in terms of the equals operation, but a sorted set performs all element comparisons using its compareTo (or compare) method, so two elements that are deemed equal by this method are, from the standpoint of the sorted set, equal." (http://docs.oracle.com/javase/6/docs/api/java/util/SortedSet.html)

Since we originally overlooked equality in order to force the set to add equal valued entries, now we have to test for equality in the keys in order for the set to actually return the entry you're looking for. This is kinda messy and definitely not how sets were intended to be used - but it works.

public string BuildAbsolute(PathString path, QueryString query = default(QueryString), FragmentString fragment = default(FragmentString))

}

Simply add this event to your text field. It will prevent a submission on pressing Enter, and you're free to add a submit button or call form.submit() as required:

onKeyPress="if (event.which == 13) return false;"

For example:

<input id="txt" type="text" onKeyPress="if (event.which == 13) return false;"></input>

The number 61.0 does indeed have an exact floating-point operation—but that's not true for all integers. If you wrote a loop that added one to both a double-precision floating point number and a 64-bit integer, eventually you'd reach a point where the 64-bit integer perfectly represents a number, but the floating point doesn't—because there aren't enough significant bits.

It's just much easier to reach the point of approximation on the right side of the decimal point. If you started writing out all the numbers in binary floating point, it'd make more sense.

Another way of thinking about it is that when you note that 61.0 is perfectly representable in base 10, and shifting the decimal point around doesn't change that, you're performing multiplication by powers of ten (10^1, 10^-1). In floating point, multiplying by powers of two does not affect the precision of the number. Try taking 61.0 and dividing it by three repeatedly for an illustration of how a perfectly precise number can lose its precise representation.

You can use:

@foreach (var item in Model)
{
  ...
  @Html.DisplayFor(modelItem => item.address + " " + item.city) 
  ...

In View:

<Button
 Height="50" Width="50"
 Style="{StaticResource MyButtonStyle}"
 Command="{Binding SmallDisp}" CommandParameter="{Binding}" 
Cursor="Hand" Visibility="{Binding Path=AdvancedFormat}"/>

In view Model:

public _advancedFormat = Visibility.visible (whatever you start with)

public Visibility AdvancedFormat
{
 get{return _advancedFormat;}
 set{
   _advancedFormat = value;
   //raise property changed here
}

You will need to have a property changed event

 protected virtual void OnPropertyChanged(PropertyChangedEventArgs e) 
    { 
        PropertyChanged.Raise(this, e); 
    } 

    protected void OnPropertyChanged(string propertyName) 
    { 
        OnPropertyChanged(new PropertyChangedEventArgs(propertyName)); 
    } 

This is how they use Model-view-viewmodel

But since you want it binded to a boolean, You will need some converter. Another way is to set a boolean outside and when that button is clicked then set the property_advancedFormat to your desired visibility.

In my case, I was moving a SProc between servers and the profile name in my TSQL code did not match the profile name on the new server.

Updating TSQL profile name == New server profile name fixed the error for me.

Just use Hash.[] with the values in the array. For example:

arr = [1,2,3,4]
Hash[*arr] #=> gives {1 => 2, 3 => 4}

Previous answers suggested (re)installing or configuring CMake, they all did not help.

Previously MinGW's compilation of Make used the filename mingw32-make.exe and now it is make.exe. Most suggested ways to configure CMake to use the other file dont work.

Just copy make.exe and rename the copy mingw32-make.exe.

There're several NuGet packages which can help with formatting. In some cases the capabilities of string.Format are enough, but you may want to auto-size columns based on content, at least.

ConsoleTableExt

ConsoleTableExt is a simple library which allows formatting tables, including tables without grid lines. (A more popular package ConsoleTables doesn't seem to support borderless tables.) Here's an example of formatting a list of objects with columns sized based on their content:

ConsoleTableBuilder
    .From(orders
        .Select(o => new object[] {
            o.CustomerName,
            o.Sales,
            o.Fee,
            o.Value70,
            o.Value30
        })
        .ToList())
    .WithColumn(
        "Customer",
        "Sales",
        "Fee",
        "70% value",
        "30% value")
    .WithFormat(ConsoleTableBuilderFormat.Minimal)
    .WithOptions(new ConsoleTableBuilderOption { DividerString = "" })
    .ExportAndWriteLine();

CsConsoleFormat

If you need more features than that, any console formatting can be achieved with CsConsoleFormat.† For example, here's formatting of a list of objects as a grid with fixed column width of 10, like in the other answers using string.Format:

ConsoleRenderer.RenderDocument(
    new Document { Color = ConsoleColor.Gray }
        .AddChildren(
            new Grid { Stroke = LineThickness.None }
                .AddColumns(10, 10, 10, 10, 10)
                .AddChildren(
                    new Div("Customer"),
                    new Div("Sales"),
                    new Div("Fee"),
                    new Div("70% value"),
                    new Div("30% value"),
                    orders.Select(o => new object[] {
                        new Div().AddChildren(o.CustomerName),
                        new Div().AddChildren(o.Sales),
                        new Div().AddChildren(o.Fee),
                        new Div().AddChildren(o.Value70),
                        new Div().AddChildren(o.Value30)
                    })
                )
        ));

It may look more complicated than pure string.Format, but now it can be customized. For example:

• If you want to auto-size columns based on content, replace AddColumns(10, 10, 10, 10, 10) with AddColumns(-1, -1, -1, -1, -1) (-1 is a shortcut to GridLength.Auto, you have more sizing options, including percentage of console window's width).

• If you want to align number columns to the right, add { Align = Right } to a cell's initializer.

• If you want to color a column, add { Color = Yellow } to a cell's initializer.

• You can change border styles and more.

Guess what? @BenCreasy was totally right!!

Starting version 1.12.0 of jQuery we can do this:

$.post({
    url: yourURL,
    data: yourData,
    contentType: 'application/json; charset=utf-8'
})
    .done(function (response) {
        //Do something on success response...
    });

I just tested it and it worked!!

        </div>
    </div>
  </div>
 #support-box {
        width: 50%;
        float: left;
        display: block;
        height: 20rem; /* is support box height you can change as per your requirement*/
        background-color:#000;
    }
    #wrapper {
        width: 90%;
        display: block;
        position: relative;
        top: 50%;
        transform: translateY(-50%);
         background:#ddd;
       margin:auto;
       height:100px; /* here the height values are automatic you can leave this if you can*/

    }
    #wrapper iframe {
        width: 100%;
        display: block;
        padding:10px;
        margin:auto;
    }

In cmd when you use > or >> the output will be only written on the file. Is it possible to see the output in the cmd windows and also save it in a file. Something similar if you use teraterm, when you can start saving all the log in a file meanwhile you use the console and view it (only for ssh, telnet and serial).

There is a quirk with this that might be relevant for some people... From the PHP docs comments.

If you want cURL to timeout in less than one second, you can use CURLOPT_TIMEOUT_MS, although there is a bug/"feature" on "Unix-like systems" that causes libcurl to timeout immediately if the value is < 1000 ms with the error "cURL Error (28): Timeout was reached". The explanation for this behavior is:

"If libcurl is built to use the standard system name resolver, that portion of the transfer will still use full-second resolution for timeouts with a minimum timeout allowed of one second."

What this means to PHP developers is "You can't use this function without testing it first, because you can't tell if libcurl is using the standard system name resolver (but you can be pretty sure it is)"

The problem is that on (Li|U)nix, when libcurl uses the standard name resolver, a SIGALRM is raised during name resolution which libcurl thinks is the timeout alarm.

The solution is to disable signals using CURLOPT_NOSIGNAL. Here's an example script that requests itself causing a 10-second delay so you can test timeouts:

if (!isset($_GET['foo'])) {
    // Client
    $ch = curl_init('http://localhost/test/test_timeout.php?foo=bar');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_NOSIGNAL, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT_MS, 200);
    $data = curl_exec($ch);
    $curl_errno = curl_errno($ch);
    $curl_error = curl_error($ch);
    curl_close($ch);

    if ($curl_errno > 0) {
        echo "cURL Error ($curl_errno): $curl_error\n";
    } else {
        echo "Data received: $data\n";
    }
} else {
    // Server
    sleep(10);
    echo "Done.";
}

From http://www.php.net/manual/en/function.curl-setopt.php#104597

you can get the value of the respective li by using this method after click

    <li value="10">10</li>

    </ul>

    <script src="pathnameofjs" type="text/javascript"></script>

JS:-

$("li").click(function ()
{       
var a = $(this).attr("value");

$("#user").html(a);//here the clicked value is showing in the div name user
console.log(a);//here the clicked value is showing in the console
});

CSS:-

ul{

You can define a context for your application say ExampleContext which will hold the context of your application and then use it to instantiate an activity like this:

var intent = new Intent(Application.ApplicationContext, typeof(Activity2));
intent.AddFlags(ActivityFlags.NewTask);
Application.ApplicationContext.StartActivity(intent);

Please bear in mind that this code is written in C# as I use MonoDroid, but I believe it is very similar to Java. For how to create an ApplicationContext look at this thread

This is how I made my Application Class

    [Application]
    public class Application : Android.App.Application, IApplication
    {
        public Application(IntPtr handle, JniHandleOwnership transfer) : base(handle, transfer)
        {

        }
        public object MyObject { get; set; }
    }

You should always use .dark for style and add the following code to make it look cool

    blurEffectView.backgroundColor = .black
    blurEffectView.alpha = 0.4

Cited answer (for reference):

Short answer: Cached is the size of the page cache. Buffers is the size of in-memory block I/O buffers. Cached matters; Buffers is largely irrelevant.

Long answer: Cached is the size of the Linux page cache, minus the memory in the swap cache, which is represented by SwapCached (thus the total page cache size is Cached + SwapCached). Linux performs all file I/O through the page cache. Writes are implemented as simply marking as dirty the corresponding pages in the page cache; the flusher threads then periodically write back to disk any dirty pages. Reads are implemented by returning the data from the page cache; if the data is not yet in the cache, it is first populated. On a modern Linux system, Cached can easily be several gigabytes. It will shrink only in response to memory pressure. The system will purge the page cache along with swapping data out to disk to make available more memory as needed.

Buffers are in-memory block I/O buffers. They are relatively short-lived. Prior to Linux kernel version 2.4, Linux had separate page and buffer caches. Since 2.4, the page and buffer cache are unified and Buffers is raw disk blocks not represented in the page cache—i.e., not file data. The Buffers metric is thus of minimal importance. On most systems, Buffers is often only tens of megabytes.

Many people on this thread and on google explain very well that attr_accessible specifies a whitelist of attributes that are allowed to be updated in bulk (all the attributes of an object model together at the same time) This is mainly (and only) to protect your application from "Mass assignment" pirate exploit.

This is explained here on the official Rails doc : Mass Assignment

attr_accessor is a ruby code to (quickly) create setter and getter methods in a Class. That's all.

Now, what is missing as an explanation is that when you create somehow a link between a (Rails) model with a database table, you NEVER, NEVER, NEVER need attr_accessor in your model to create setters and getters in order to be able to modify your table's records.

This is because your model inherits all methods from the ActiveRecord::Base Class, which already defines basic CRUD accessors (Create, Read, Update, Delete) for you. This is explained on the offical doc here Rails Model and here Overwriting default accessor (scroll down to the chapter "Overwrite default accessor")

Say for instance that: we have a database table called "users" that contains three columns "firstname", "lastname" and "role" :

SQL instructions :

CREATE TABLE users (
  firstname string,
  lastname string
  role string
);

I assumed that you set the option config.active_record.whitelist_attributes = true in your config/environment/production.rb to protect your application from Mass assignment exploit. This is explained here : Mass Assignment

Your Rails model will perfectly work with the Model here below :

class User < ActiveRecord::Base

end

However you will need to update each attribute of user separately in your controller for your form's View to work :

def update
    @user = User.find_by_id(params[:id])
    @user.firstname = params[:user][:firstname]
    @user.lastname = params[:user][:lastname]

    if @user.save
        # Use of I18 internationalization t method for the flash message
        flash[:success] = t('activerecord.successful.messages.updated', :model => User.model_name.human)
    end

    respond_with(@user)
end

Now to ease your life, you don't want to make a complicated controller for your User model. So you will use the attr_accessible special method in your Class model :

class User < ActiveRecord::Base

  attr_accessible :firstname, :lastname

end

So you can use the "highway" (mass assignment) to update :

def update
    @user = User.find_by_id(params[:id])

    if @user.update_attributes(params[:user])
        # Use of I18 internationlization t method for the flash message
        flash[:success] = t('activerecord.successful.messages.updated', :model => User.model_name.human)
    end

    respond_with(@user)
end

You didn't add the "role" attributes to the attr_accessible list because you don't let your users set their role by themselves (like admin). You do this yourself on another special admin View.

Though your user view doesn't show a "role" field, a pirate could easily send a HTTP POST request that include "role" in the params hash. The missing "role" attribute on the attr_accessible is to protect your application from that.

You can still modify your user.role attribute on its own like below, but not with all attributes together.

@user.role = DEFAULT_ROLE

Why the hell would you use the attr_accessor?

Well, this would be in the case that your user-form shows a field that doesn't exist in your users table as a column.

For instance, say your user view shows a "please-tell-the-admin-that-I'm-in-here" field. You don't want to store this info in your table. You just want that Rails send you an e-mail warning you that one "crazy" ;-) user has subscribed.

To be able to make use of this info you need to store it temporarily somewhere. What more easy than recover it in a user.peekaboo attribute ?

So you add this field to your model :

class User < ActiveRecord::Base

  attr_accessible :firstname, :lastname
  attr_accessor :peekaboo

end

So you will be able to make an educated use of the user.peekaboo attribute somewhere in your controller to send an e-mail or do whatever you want.

ActiveRecord will not save the "peekaboo" attribute in your table when you do a user.save because she don't see any column matching this name in her model.

I think you are getting confused about what the a:active CSS selector does. This will only change the colour of your link when you click it (and only for the duration of the click i.e. how long your mouse button stays down). What you need to do is introduce a new class e.g. .selected into your CSS and when you select a link, update the selected menu item with new class e.g.

<div class="menuBar">
    <ul>
        <li class="selected"><a href="index.php">HOME</a></li>
        <li><a href="two.php">PORTFOLIO</a></li>
        ....
    </ul>
</div>

// specific CSS for your menu
div.menuBar li.selected a { color: #FF0000; } 
// more general CSS
li.selected a { color: #FF0000; }

You will need to update your template page to take in a selectedPage parameter.

Use toString when you need to display the name to the user.

Use name when you need the name for your program itself, e.g. to identify and differentiate between different enum values.

Below is my onload event handler.

I use an IFRAME within a jQuery UI dialog. Different usages will need some adjustments. This seems to do the trick for me (for now) in Internet Explorer 8 and Firefox 3.5. It might need some extra tweaking, but the general idea should be clear.

    function onLoadDialog(frame) {
    try {
        var body = frame.contentDocument.body;
        var $body = $(body);
        var $frame = $(frame);
        var contentDiv = frame.parentNode;
        var $contentDiv = $(contentDiv);

        var savedShow = $contentDiv.dialog('option', 'show');
        var position = $contentDiv.dialog('option', 'position');
        // disable show effect to enable re-positioning (UI bug?)
        $contentDiv.dialog('option', 'show', null);
        // show dialog, otherwise sizing won't work
        $contentDiv.dialog('open');

        // Maximize frame width in order to determine minimal scrollHeight
        $frame.css('width', $contentDiv.dialog('option', 'maxWidth') -
                contentDiv.offsetWidth + frame.offsetWidth);

        var minScrollHeight = body.scrollHeight;
        var maxWidth = body.offsetWidth;
        var minWidth = 0;
        // decrease frame width until scrollHeight starts to grow (wrapping)
        while (Math.abs(maxWidth - minWidth) > 10) {
            var width = minWidth + Math.ceil((maxWidth - minWidth) / 2);
            $body.css('width', width);
            if (body.scrollHeight > minScrollHeight) {
                minWidth = width;
            } else {
                maxWidth = width;
            }
        }
        $frame.css('width', maxWidth);
        // use maximum height to avoid vertical scrollbar (if possible)
        var maxHeight = $contentDiv.dialog('option', 'maxHeight')
        $frame.css('height', maxHeight);
        $body.css('width', '');
        // correct for vertical scrollbar (if necessary)
        while (body.clientWidth < maxWidth) {
            $frame.css('width', maxWidth + (maxWidth - body.clientWidth));
        }

        var minScrollWidth = body.scrollWidth;
        var minHeight = Math.min(minScrollHeight, maxHeight);
        // descrease frame height until scrollWidth decreases (wrapping)
        while (Math.abs(maxHeight - minHeight) > 10) {
            var height = minHeight + Math.ceil((maxHeight - minHeight) / 2);
            $body.css('height', height);

I had to stopPropigation and preventDefault in order to prevent a button expanding an accordion item that it sat above.

So...

@Component({
  template: `
    <button (click)="doSomething($event); false">Test</button>
  `
})
export class MyComponent {
  doSomething(e) {
    e.stopPropagation();
    // do other stuff...
  }
}

You created the UIButton is added the ViewController, The following instance method to change UIFont, tintColor and TextColor of the UIButton

Objective-C

 buttonName.titleLabel.font = [UIFont fontWithName:@"LuzSans-Book" size:15];
 buttonName.tintColor = [UIColor purpleColor];
 [buttonName setTitleColor:[UIColor purpleColor] forState:UIControlStateNormal];

Swift

buttonName.titleLabel.font = UIFont(name: "LuzSans-Book", size: 15)
buttonName.tintColor = UIColor.purpleColor()
buttonName.setTitleColor(UIColor.purpleColor(), forState: .Normal)

Swift3

buttonName.titleLabel?.font = UIFont(name: "LuzSans-Book", size: 15)
buttonName.tintColor = UIColor.purple
buttonName.setTitleColor(UIColor.purple, for: .normal)

For me PHP is the easiest way to do it:

<?php
echo "Here are our files";
$path = ".";
$dh = opendir($path);
$i=1;
while (($file = readdir($dh)) !== false) {
    if($file != "." && $file != ".." && $file != "index.php" && $file != ".htaccess" && $file != "error_log" && $file != "cgi-bin") {
        echo "<a href='$path/$file'>$file</a><br /><br />";
        $i++;
    }
}
closedir($dh);
?> 

Place this in your directory and set where you want it to search on the $path. The first if statement will hide your php file and .htaccess and the error log. It will then display the output with a link. This is very simple code and easy to edit.

A class literal is an expression consisting of the name of a class, interface, array, or primitive type, or the pseudo-type void, followed by a '.' and the token class. One of the changes in JDK 5.0 is that the class java.lang.Class is generic, java.lang.Class Class<T>, therefore:

Class<Print> p = Print.class;

This is the right way to execute a .jar, and whatever one class in that .jar should have main() and the following are the parameters to it :

java -DLB="uk" -DType="CLIENT_IND" -jar com.fbi.rrm.rrm-batchy-1.5.jar

Use a custom ID if possible if you would like to apply the action to only that button.

HTML

<button class="pushDontpush">PUSH ME</button>

jQuery

$("#pushDontpush").click(function() { 
    if ($(this).text() == "PUSH ME") { 
        $(this).text("DON'T PUSH ME"); 
    } else { 
        $(this).text("PUSH ME"); 
    }; 
});

You will have to add it through code. Try this:

    // 1.create UIView programmetically
    var myView = UIView(frame: CGRectMake(100, 100, 100, 100))
    // 2.add myView to UIView hierarchy
    self.view.addSubview(myView) 
    // 3. add action to myView
    let gesture = UITapGestureRecognizer(target: self, action: "someAction:")
    // or for swift 2 +
    let gestureSwift2AndHigher = UITapGestureRecognizer(target: self, action:  #selector (self.someAction (_:)))
    self.myView.addGestureRecognizer(gesture)

    func someAction(sender:UITapGestureRecognizer){     
       // do other task
    }

    // or for Swift 3
    func someAction(_ sender:UITapGestureRecognizer){     
       // do other task
    }

    // or for Swift 4
    @objc func someAction(_ sender:UITapGestureRecognizer){     
       // do other task
    }

    // update for Swift UI

    Text("Tap me!")
        .tapAction {
             print("Tapped!")
        }

TLDR - In addition to the previous responses. There might be a problem with the version of the fastboot command. Try to download the newest one via Android SDK Manager instead of default one available in the OS repository.

There is one more thing you can do to fix this issue. I had the similar problem when trying to flash Nexus Player. All the adb commands we working fine while in normal boot mode. However, after switching to fastboot mode I wasn't able to execute fastboot commands. My device was not visible in the output of the fastboot devices command. I've set the right rules in /etc/udev/rules.d/11-android.rules file. The lsusb command showed that the device has been pluged in.

The soultion was quite simple. I've downloaded the the fastboot via Android Studio's SDK Manager instead of using the default one available in Ubuntu packages.

All you need is sdkmanager. Download the Android SDK Platform Tools and replace the default /usr/bin/fastboot with the new one.

There's now (C# 6) a more succinct way to do it: string interpolation.

From another question's answer:

In C# 6 you can use string interpolation:

string name = "John";
string result = $"Hello {name}";

The syntax highlighting for this in Visual Studio makes it highly readable and all of the tokens are checked.

For me the issue had to do with the parameters assigned to the package.

 In SSMS, Navigate to:
 "Integration Services Catalog -> SSISDB -> Project Folder Name -> Projects -> Project Name" 

Make sure you right click on your "Project Name" and then validate that 32-bit runtime is set correctly and that the parameters that are used by default are instantiated properly. Check parameter NAMES and initial values. For my package, I was using values that were not correct and so I had to repopulate the parameter defaults prior to executing my package. Check the values you are using against the defaults you have set for your parameters you have set up in your SSIS package. Once these match the issue should be resolved (for some)

[I have a point to make that I cant see above]

"Everyone unit tests, they don't necessarily realise it - FACT"

Think about it, you write a function to maybe parse a string and remove new line characters. As a newbie developer you either run a few cases through it from the command line by implementing it in Main() or you whack together a visual front end with a button, tie up your function to a couple of text boxes and a button and see what happens.

That is unit testing - basic and badly put together but you test the piece of code for a few cases.

You write something more complex. It throws errors when you throw a few cases through (unit testing) and you debug into the code and trace though. You look at values as you go through and decide if they are right or wrong. This is unit testing to some degree.

Unit testing here is really taking that behaviour, formalising it into a structured pattern and saving it so that you can easily re-run those tests. If you write a "proper" unit test case rather than manually testing, it takes the same amount of time, or maybe less as you get experienced, and you have it available to repeat again and again

Fetching data with either null and value on where conditions are very tricky. Even if you are using straight Where and OrWhereNotNull condition then for every rows you will fetch both items ignoring other where conditions if applied. For example if you have more where conditions it will mask out those and still return with either null or value items because you used orWhere condition

The best way so far I found is as follows. This works as where (whereIn Or WhereNotNull)

Code::where(function ($query) {
            $query->where('to_be_used_by_user_id', '!=' , 2)->orWhereNull('to_be_used_by_user_id');                  
        })->get();

Open Command Prompt as Administrator in Windows . Go to the directory where Jenkins is installed. and stop the Jenkins service first, using jenkins.exe stop

type the command to change the port using, java -jar jenkins.war --httpPort=9090 (enter the port number you want to use).

and at-last, restart the Jenkins services, using jenkins.exe restart

For me, the error was actually produced by "Feature 'async main' is not available in C# 7.0. Please use language version 7.1 or greater". This issue was resulting in the "Does not contain a static 'main' method suitable for an entry point" message in the Error List, but the Output window showed the "not available" error. To correct this, I changed the language version from 'C# latest minor version (default)' to 'C# latest minor version (latest)' under Advanced Build Settings.

I was in search of something similar for IPv4 addresses - a regex that also stopped commonly used private ip addresses from being validated (192.168.x.y, 10.x.y.z, 172.16.x.y) so used negative look aheads to accomplish this:

(?!(10\.|172\.(1[6-9]|2\d|3[01])\.|192\.168\.).*)
(?!255\.255\.255\.255)(25[0-5]|2[0-4]\d|[1]\d\d|[1-9]\d|[1-9])
(\.(25[0-5]|2[0-4]\d|[1]\d\d|[1-9]\d|\d)){3}

(These should be on one line of course, formatted for readability purposes on 3 separate lines)

It may not be optimised for speed, but works well when only looking for 'real' internet addresses.

Things that will (and should) fail:

0.1.2.3         (0.0.0.0/8 is reserved for some broadcasts)
10.1.2.3        (10.0.0.0/8 is considered private)
172.16.1.2      (172.16.0.0/12 is considered private)
172.31.1.2      (same as previous, but near the end of that range)
192.168.1.2     (192.168.0.0/16 is considered private)
255.255.255.255 (reserved broadcast is not an IP)
.2.3.4
1.2.3.
1.2.3.256
1.2.256.4
1.256.3.4
256.2.3.4
1.2.3.4.5
1..3.4

IPs that will (and should) work:

1.0.1.0         (China)
8.8.8.8         (Google DNS in USA)
100.1.2.3       (USA)
172.15.1.2      (USA)
172.32.1.2      (USA)
192.167.1.2     (Italy)

Provided in case anybody else is looking for validating 'Internet IP addresses not including the common private addresses'

My problem turned out to be, I had altered a table to add a column called Char. As this is a reserved word in MS Access it needed square brakcets (Single or double quote are no good) in order for the alter statement to work before I could then update the newly created column.

I found the answer to this problem here

Just do

mb_convert_encoding($data['name'], 'UTF-8', 'UTF-8');

if you have bash

str1="MATCH"
str2="match"
shopt -s nocasematch
case "$str1" in
 $str2 ) echo "match";;
 *) echo "no match";;
esac

otherwise, you should tell us what shell you are using.

alternative, using awk

str1="MATCH"
str2="match"
awk -vs1="$str1" -vs2="$str2" 'BEGIN {
  if ( tolower(s1) == tolower(s2) ){
    print "match"
  }
}'

I was used to Home/End getting me to the start and end of lines in Insert mode (from use in Windows and I think Linux), which Mac doesn't support. This is particularly annoying because when I'm using vim on a remote system, I also can't easily do it. After some painful trial and error, I came up with these .vimrc lines which do the same thing, but bound to Ctrl-A for the start of the line and Ctrl-D for the end of the line. (For some reason, Ctrl-E I guess is reserved or at least I couldn't figure a way to bind it.) Enjoy.

            FluentIterable.from(userList).firstMatch(new Predicate<User>() {
                @Override
                public boolean apply(@Nullable User input) {
                    return input.getName().equals(name);
                }
            });
    return userOptional.isPresent() ? userOptional.get() : null; // return user if found otherwise return null if user name don't exist in user list
}

use Select().Distinct()

for example

DBContext db = new DBContext();
var data= db.User_Food_UserIntakeFood .Select( ).Distinct();

pyinstaller --clean --onefile --icon=default.ico Registry.py

It works for Me

concept47's approach is the right way to do it, but I'd advise to merge with the --no-ff option in order to keep your commit history clear.

git checkout develop
git pull --rebase
git checkout NewFeatureBranch
git merge --no-ff master

So ... you need to change some things in your code

<form method="POST" id="form-pass">
Password: <input type="text" name="pwd" id="input-pwd">
<input type="submit" value="Submit">
</form>

<script>
var form = document.querySelector('#form-pass');
var pwd = document.querySelector('#input-pwd');
pwd.focus();
form.onsubmit = checkForm;

function checkForm() {
  alert(pwd.value);
}
</script>

Try this way.

ULs don't have a name attribute, but you can reference the ul by tag name.

Try replacing line 3 in your script with this:

var sub = cat.getElementsByTagName("UL");

Michael has given a very comprehensive answer, but I'd like to point out a few things which you can still do to be able to use grids in IE in a nearly painless way.

The repeat functionality is supported

You can still use the repeat functionality, it's just hiding behind a different syntax. Instead of writing repeat(4, 1fr), you have to write (1fr)[4]. That's it. See this series of articles for the current state of affairs: https://css-tricks.com/css-grid-in-ie-debunking-common-ie-grid-misconceptions/

Supporting grid-gap

Grid gaps are supported in all browsers except IE. So you can use the @supports at-rule to set the grid-gaps conditionally for all new browsers:

Example:

.grid {
  display: grid;
}
.item {
  margin-right: 1rem;
  margin-bottom: 1rem;
}
@supports (grid-gap: 1rem) {
  .grid {
    grid-gap: 1rem;
  }
  .item {
    margin-right: 0;
    margin-bottom: 0;
  }
}

It's a little verbose, but on the plus side, you don't have to give up grids altogether just to support IE.

Use Autoprefixer

I can't stress this enough - half the pain of grids is solved just be using autoprefixer in your build step. Write your CSS in a standards-complaint way, and just let autoprefixer do it's job transforming all older spec properties automatically. When you decide you don't want to support IE, just change one line in the browserlist config and you'll have removed all IE-specific code from your built files.

Found successful workaround that is applicable for my scenario:

Don't log off, just lock the session!

Since this script is running on a Domain Controller, I am logging in to the server via the Remote Desktop console and then log off of the server to terminate my session. When setting up the Task in the Task Scheduler, I was using user accounts and local services that did not have access to run in an offline mode, or logon strictly to run a script.

Thanks to some troubleshooting assistance from Cole, I got to thinking about the RunAs function and decided to try and work around the non-functioning logons.

Starting in the Task Scheduler, I deleted my manually created Tasks. Using the new function in Server 2008 R2, I navigated to a 4740 Security Event in the Event Viewer, and used the right-click > Attach Task to this Event... and followed the prompts, pointing to my script on the Action page. After the Task was created, I locked my session and terminated my Remote Desktop Console connection. WIth the profile 'Locked' and not logged off, everything works like it should.

Taken from: http://www.w3.org/Style/Examples/007/units:

The em is simply the font size. In an element with a 2in font, 1em thus means 2in. Expressing sizes, such as margins and paddings, in em means they are related to the font size, and if the user has a big font (e.g., on a big screen) or a small font (e.g., on a handheld device), the sizes will be in proportion. Declarations such as 'text-indent: 1.5em' and 'margin: 1em' are extremely common in CSS.

em is basically CSS property for font sizes.

<%@page import="java.text.SimpleDateFormat"%>
<%@page import="java.util.Date"%>
<%@page import="java.util.Locale"%>

<html>
<head>
<title>Date Format</title>
</head>
<body>
<%
String stringDate = "Fri May 13 2011 19:59:09 GMT 0530";
Date stringDate1 = new SimpleDateFormat("EEE MMM dd yyyy HH:mm:ss Z", Locale.ENGLISH).parse(stringDate);
String stringDate2 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(stringDate1);

out.println(stringDate2);
%>

</html>

The sequence is CR (Carriage Return) - LF (Line Feed). Remember dot matrix printers? Exactly. So - the correct order is \r \n

If you want to save the model and wants to resume the training later:

Single GPU: Save:

state = {
        'epoch': epoch,
        'state_dict': model.state_dict(),
        'optimizer': optimizer.state_dict(),
}
savepath='checkpoint.t7'
torch.save(state,savepath)

Load:

checkpoint = torch.load('checkpoint.t7')
model.load_state_dict(checkpoint['state_dict'])
optimizer.load_state_dict(checkpoint['optimizer'])
epoch = checkpoint['epoch']

Multiple GPU: Save

state = {
        'epoch': epoch,
        'state_dict': model.module.state_dict(),
        'optimizer': optimizer.state_dict(),
}
savepath='checkpoint.t7'
torch.save(state,savepath)

Load:

checkpoint = torch.load('checkpoint.t7')
model.load_state_dict(checkpoint['state_dict'])
optimizer.load_state_dict(checkpoint['optimizer'])
epoch = checkpoint['epoch']

#Don't call DataParallel before loading the model otherwise you will get an error

model = nn.DataParallel(model) #ignore the line if you want to load on Single GPU

I found I could improve the situation a little with CSS dedicated to Webkit (Safari, Chrome). However, I had to set a fixed width and height on the field because the font change will resize the field.

@media screen and (-webkit-min-device-pixel-ratio:0){ /* START WEBKIT */
  INPUT[type="password"]{
  font-family:Verdana,sans-serif;
  height:28px;
  font-size:19px;
  width:223px;
  padding:5px;
  }
} /* END WEBKIT */

import csv first and use csv.DictReader its easy to process...

I'd use either String.split or a regex:

Using String.split

String[] numberSplit = yourString.split(":") ; 
String numbers = numberSplit[ (numberSplit.length-1) ] ; //!! last array element

Using RegEx (requires import java.util.regex.*)

String numbers = "" ;
Matcher numberMatcher = Pattern.compile("[0-9]{7}").matcher(yourString) ;
    if( matcher.find() ) {
            numbers = matcher.group(0) ;
    } 

You will need to cast or convert as a CHAR datatype, there is no varchar datatype that you can cast/convert data to:

select CAST(id as CHAR(50)) as col1 
from t9;

select CONVERT(id, CHAR(50)) as colI1 
from t9;

See the following SQL — in action — over at SQL Fiddle:

/*! Build Schema */
create table t9 (id INT, name VARCHAR(55));
insert into t9 (id, name) values (2, 'bob');

/*! SQL Queries */
select CAST(id as CHAR(50)) as col1 from t9;
select CONVERT(id, CHAR(50)) as colI1 from t9;

Besides the fact that you were trying to convert to an incorrect datatype, the syntax that you were using for convert was incorrect. The convert function uses the following where expr is your column or value:

 CONVERT(expr,type)

or

 CONVERT(expr USING transcoding_name)

Your original query had the syntax backwards.

To plot multiple categorical features as bar charts on the same plot, I would suggest:

import pandas as pd
import matplotlib.pyplot as plt

df = pd.DataFrame(
    {
        "colour": ["red", "blue", "green", "red", "red", "yellow", "blue"],
        "direction": ["up", "up", "down", "left", "right", "down", "down"],
    }
)

categorical_features = ["colour", "direction"]
fig, ax = plt.subplots(1, len(categorical_features))
for i, categorical_feature in enumerate(df[categorical_features]):
    df[categorical_feature].value_counts().plot("bar", ax=ax[i]).set_title(categorical_feature)
fig.show()

We can get a single using limit in query

$query = $this->db->get_where('mytable', array('id' => $id), $limit, $offset);

 $query = $this->db->get_where('mytable', array('id' => $id), $limit, $offset);

Could you please try this ?

Create another item in post such as post.link then assign the link to it before send post to the render function.

post.link = '/posts/+ id.toString();

So, the above render function should be following instead.

return <li key={post.id}><a href={post.link}>{post.title}</a></li>

Given your Object:

var foo = { 'bar' : 'baz' }

To get bar, use:

Object.keys(foo)[0]

To get baz, use:

foo[Object.keys(foo)[0]]

Assuming a single object

For me, it was caused before I referred a library (specifically typeORM, using the ormconfig.js file, under the entities key) to the src folder, instead of the dist folder...

   "entities": [
      "src/db/entity/**/*.ts", // Pay attention to "src" and "ts" (this is wrong)
   ],

instead of

   "entities": [
      "dist/db/entity/**/*.js", // Pay attention to "dist" and "js" (this is the correct way)
   ],

The auto keyword is an important and frequently used keyword for C ++.When initializing a variable, auto keyword is used for type inference(also called type deduction).

There are 3 different rules regarding the auto keyword.

First Rule

auto x = expr; ----> No pointer or reference, only variable name. In this case, const and reference are ignored.

int  y = 10;
int& r = y;
auto x = r; // The type of variable x is int. (Reference Ignored)

const int y = 10;
auto x = y; // The type of variable x is int. (Const Ignored)

int y = 10;
const int& r = y;
auto x = r; // The type of variable x is int. (Both const and reference Ignored)

const int a[10] = {};
auto x = a; //  x is const int *. (Array to pointer conversion)

Note : When the name defined by auto is given a value with the name of a function,
       the type inference will be done as a function pointer.

Second Rule

auto& y = expr; or auto* y = expr; ----> Reference or pointer after auto keyword.

Warning : const is not ignored in this rule !!! .

int y = 10;
auto& x = y; // The type of variable x is int&.

Warning : In this rule, array to pointer conversion (array decay) does not occur !!!.

auto& x = "hello"; // The type of variable x is  const char [6].

static int x = 10;
auto y = x; // The variable y is not static.Because the static keyword is not a type. specifier 
            // The type of variable x is int.

Third Rule

auto&& z = expr; ----> This is not a Rvalue reference.

Warning : If the type inference is in question and the && token is used, the names introduced like this are called "Forwarding Reference" (also called Universal Reference).

auto&& r1 = x; // The type of variable r1 is int&.Because x is Lvalue expression. 

auto&& r2 = x+y; // The type of variable r2 is int&&.Because x+y is PRvalue expression. 

All previous answers are correct, here is one more and easy way to do it. For example, create a Dict data structure to serialize and deserialize an object

(Notice None is Null in python and I'm intentionally using this to demonstrate how you can store null and convert it to json null)

import json
print('serialization')
myDictObj = { "name":"John", "age":30, "car":None }
##convert object to json
serialized= json.dumps(myDictObj, sort_keys=True, indent=3)
print(serialized)
## now we are gonna convert json to object
deserialization=json.loads(serialized)
print(deserialization)

No, a view consists of a single SELECT statement. You cannot create or drop tables in a view.

Maybe a common table expression (CTE) can solve your problem. CTEs are temporary result sets that are defined within the execution scope of a single statement and they can be used in views.

Example (taken from here) - you can think of the SalesBySalesPerson CTE as a temporary table:

CREATE VIEW vSalesStaffQuickStats
AS
  WITH SalesBySalesPerson (SalesPersonID, NumberOfOrders, MostRecentOrderDate)
      AS
      (
            SELECT SalesPersonID, COUNT(*), MAX(OrderDate)
            FROM Sales.SalesOrderHeader
            GROUP BY SalesPersonID
      )
  SELECT E.EmployeeID,
         EmployeeOrders = OS.NumberOfOrders,
         EmployeeLastOrderDate = OS.MostRecentOrderDate,
         E.ManagerID,
         ManagerOrders = OM.NumberOfOrders,
         ManagerLastOrderDate = OM.MostRecentOrderDate
  FROM HumanResources.Employee AS E
  INNER JOIN SalesBySalesPerson AS OS ON E.EmployeeID = OS.SalesPersonID
  LEFT JOIN SalesBySalesPerson AS OM ON E.ManagerID = OM.SalesPersonID
GO

Performance considerations

Which are more performant, CTE or temporary tables?

No, they're not the same. Aside from the escaping on the client-side that it provides, a prepared statement is compiled on the server-side once, and then can be passed different parameters at each execution. Which means you can do:

$sth = $db->prepare("SELECT * FROM table WHERE foo = ?");
$sth->execute(array(1));
$results = $sth->fetchAll(PDO::FETCH_ASSOC);

$sth->execute(array(2));
$results = $sth->fetchAll(PDO::FETCH_ASSOC);

They generally will give you a performance improvement, although not noticeable on a small scale. Read more on prepared statements (MySQL version).

I think I may have a better solution for having a fully responsive iframe (a vimeo video in my case) embed on your site. Nest the iframe in a div. Give them the following styles:

div {
    width: 100%;
    height: 0;
    padding-bottom: 56%; /* Change this till it fits the dimensions of your video */
    position: relative;
}

div iframe {
    width: 100%;
    height: 100%;
    position: absolute;
    display: block;
    top: 0;
    left: 0;
}

Just did it now for a client, and it seems to be working: http://themilkrunsa.co.za/

After 4 hours, of trying everything... Windows 2008 R2 the files were green in Window Explorer. The files were marked for encryption and arching that came from the zip file. unchecking those options in the file property fixed the issue for me.

Any input from a client are ways to be vulnerable. Including all forms and the query string. This includes all HTTP verbs.

There are 3rd party solutions that can crawl an application and detect when an injection could happen.

(answer suitable for a subset of users)

If you're on (any recent) macOS, and even if you're away from your Time Machine disk, the OS will have saved hourly backups, called local snapshots.

Enter Time Machine and navigate to the file you lost. The OS will then ask you:

The location to which you're restoring "file.ext" already contains an
item with the same name. Do you want to replace it with the one you're
restoring?

You should be able to recover the file(s) you lost.

The only way to prevent SQL injection is with parameterized SQL. It simply isn't possible to build a filter that's smarter than the people who hack SQL for a living.

So use parameters for all input, updates, and where clauses. Dynamic SQL is simply an open door for hackers, and that includes dynamic SQL in stored procedures. Parameterize, parameterize, parameterize.

There are a few technical differences. Abstract classes can still do more in comparison to Java 8 interfaces:

1. Abstract class can have a constructor.
2. Abstract classes are more structured and can hold a state.

Conceptually, main purpose of defender methods is a backward compatibility after introduction of new features (as lambda-functions) in Java 8.

(For the record and before the thread disappears on the msdn forums) You can't disable the warning (at least under VS2010) because it is on the list of the warnings that can't be disabled (so /wd4099 will not work), but what you can do instead is patch link.exe (usually C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\link.exe) to remove it from said list . Sounds like a jackhammer, i know. It works though.

For instance, if you want to remove the warning for 4099, open link.exe with an hex editor, goto line 15A0 which reads 03 10 (little endian for 4099) and replace it with FF 00 (which does not exist.)

It's caused by n % x, when x is 0. You should have x start at 2 instead. You should not use floating point here at all, since you only need integer operations.

General notes:

1. Try to format your code better. Focus on using a consistent style. E.g. you have one else that starts immediately after a if brace (not even a space), and another with a newline in between.
2. Don't use globals unless necessary. There is no reason for q to be global.
3. Don't return without a value in a non-void (int) function.

You should use profiles.

<profiles>
    <profile>
        <id>otherOutputDir</id>
        <build>
            <directory>yourDirectory</directory>
        </build>
    </profile>
</profiles>

And start maven with your profile

mvn compile -PotherOutputDir

If you really want to define your directory from the command line you could do something like this (NOT recommended at all) :

<properties>
    <buildDirectory>${project.basedir}/target</buildDirectory>
</properties>

<build>
    <directory>${buildDirectory}</directory>
</build>

And compile like this :

mvn compile -DbuildDirectory=test

That's because you can't change the target directory by using -Dproject.build.directory

I also want to add Python | Converting all strings in list to integers

Method #1 : Naive Method

# Python3 code to demonstrate 
# converting list of strings to int 
# using naive method 

# initializing list 
test_list = ['1', '4', '3', '6', '7'] 

# Printing original list

for i in range(0, len(test_list)): 
    test_list[i] = int(test_list[i]) 
    

# Printing modified list 
print ("Modified list is : " + str(test_list)) 

Output:

Original list is : ['1', '4', '3', '6', '7']
Modified list is : [1, 4, 3, 6, 7]

Method #2 : Using list comprehension

In my case this error was caused by hot reloading, while introducing new classes. In that stage of the project, use normal watchers to compile your code.

For those who don't want to go for Newtonsoft Json.Net or DataContractJsonSerializer for some reason (I can't think of any :) ), here is an implementation of JavaScriptConverter that supports DataContract and enum to string conversion -

Note: This DataContractJavaScriptConverter will only handle DataContract classes defined in the assembly where it is placed. If you want classes from separate assemblies, modify the _supportedTypes list accordingly in the static constructror.

This can be used as follows -

    JavaScriptSerializer serializer = new JavaScriptSerializer();
    serializer.RegisterConverters(new JavaScriptConverter[] { new DataContractJavaScriptConverter(true) });
    DataObject dataObject = serializer.Deserialize<DataObject>(JsonData);

The DataObject class would look like this -

    using System.Runtime.Serialization;

    [DataContract]
    public class DataObject
    {
        [DataMember(Name = "user_id")]
        public int UserId { get; set; }

        [DataMember(Name = "detail_level")]
        public string DetailLevel { get; set; }
    }

Please note that this solution doesn't handle EmitDefaultValue and Order properties supported by DataMember attribute.

This isn't Perl; you don't want to force-fit multiple lines worth of code onto a single line. Write a function, then calling the function takes one line of code.

An alternative tool to py2exe is bbfreeze which generates executables for windows and linux. It's newer than py2exe and handles eggs quite well. I've found it magically works better without configuration for a wide variety of applications.

If you are a student you can get a free private repository at https://github.com/edu

Update

As noted in another answer, now there is an option for private repos also for simple users

I've found what seems like a good solution to this issue. I am using VS 2008 C#. My solution involves the use of distinct namespaces between multiple configuration files. I've posted the solution on my blog: http://tommiecarter.blogspot.com/2011/02/how-to-access-multiple-config-files-in.html.

For example:

This namespace read/writes dll settings:

var x = company.dlllibrary.Properties.Settings.Default.SettingName;
company.dlllibrary.Properties.Settings.Default.SettingName = value;

This namespace read/writes the exe settings:

company.exeservice.Properties.Settings.Default.SettingName = value;
var x = company.exeservice.Properties.Settings.Default.SettingName;

There are some caveats mentioned in the article. HTH

This is how we do it:

private static void OverrideDefaultFont(string defaultFontNameToOverride, string customFontFileNameInAssets, AssetManager assets)
{
    //Load custom Font from File                
    Typeface customFontTypeface = Typeface.CreateFromAsset(assets, customFontFileNameInAssets);

    //Get Fontface.Default Field by reflection
    Class typeFaceClass = Class.ForName("android.graphics.Typeface");
    Field defaultFontTypefaceField = typeFaceClass.GetField(defaultFontNameToOverride);

    defaultFontTypefaceField.Accessible = true;
    defaultFontTypefaceField.Set(null, customFontTypeface);
}

My approach:

• define a default constraint on the ModDate column with a value of GETDATE() - this handles the INSERT case

• have a AFTER UPDATE trigger to update the ModDate column

Something like:

CREATE TRIGGER trg_UpdateTimeEntry
ON dbo.TimeEntry
AFTER UPDATE
AS
    UPDATE dbo.TimeEntry
    SET ModDate = GETDATE()
    WHERE ID IN (SELECT DISTINCT ID FROM Inserted)

This is how I did this so that only one progress dialog can be open at a time. Based off of the answer from Suraj Bajaj

private ProgressDialog progress;



public void showLoadingDialog() {

    if (progress == null) {
        progress = new ProgressDialog(this);
        progress.setTitle(getString(R.string.loading_title));
        progress.setMessage(getString(R.string.loading_message));
    }
    progress.show();
}

public void dismissLoadingDialog() {

    if (progress != null && progress.isShowing()) {
        progress.dismiss();
    }
}

I also had to use

protected void onResume() {
    dismissLoadingDialog();
    super.onResume();
}

Sure You can. I'd say that You should.

Here you get JSONObject so change this line:

JSONArray jsonArray = new JSONArray(readlocationFeed); 

with following:

JSONObject jsnobject = new JSONObject(readlocationFeed);

and after

JSONArray jsonArray = jsnobject.getJSONArray("locations");
for (int i = 0; i < jsonArray.length(); i++) {
    JSONObject explrObject = jsonArray.getJSONObject(i);
}

Use a BackgroundWorker. It will allow you to get callbacks on completion and allow you to track progress. You can set the Result value on the event arguments to the resulting value.

    public void UseBackgroundWorker()
    {
        var worker = new BackgroundWorker();
        worker.DoWork += DoWork;
        worker.RunWorkerCompleted += WorkDone;
        worker.RunWorkerAsync("input");
    }

    public void DoWork(object sender, DoWorkEventArgs e)
    {
        e.Result = e.Argument.Equals("input");
        Thread.Sleep(1000);
    }

    public void WorkDone(object sender, RunWorkerCompletedEventArgs e)
    {
        var result = (bool) e.Result;
    }

In core php you can do like this :

$method = $_SERVER['REQUEST_METHOD'];

switch ($method) {
  case 'GET':
    //Here Handle GET Request
    echo 'You are using '.$method.' Method';
    break;
  case 'POST':
    //Here Handle POST Request
    echo 'You are using '.$method.' Method';
    break;
  case 'PUT':

    echo 'You are using '.$method.' Method';
    break;
  case 'DELETE':

      echo 'You are using '.$method.' Method';
      break;
  case 'VIEW':
      //Here Handle VIEW Request
      echo 'You are using '.$method.' Method';
      break;
  Default:
    echo 'You are using '.$method.' Method';
  break;

Setting the QT_QPA_PLATFORM_PLUGIN_PATH environment variable to %QTDIR%\plugins\platforms\ worked for me.

It was also mentioned here and here.

Using the size attribute is the most practical solution, however there are quirks when it is applied to select elements with only two or three options.

• Setting the size attribute value to "0" or "1" will mostly render a default select element (dropdown).
• Setting the size attribute to a value greater than "1" will mostly render a selection list with a height capable of displaying at least four items. This also applies to lists with only two or three items, leading to unintended white-space.

Simple JavaScript can be used to set the size attribute to the correct value automatically, e.g. see this fiddle.

$(function() {
    $("#autoheight").attr("size", parseInt($("#autoheight option").length)); 
});

As mentioned above, this solution does not solve the issue when there are only two or three options.

This is the error line:

if (called_from.equalsIgnoreCase("add")) {  --->38th error line

This means that called_from is null. Simple check if it is null above:

String called_from = getIntent().getStringExtra("called");

if(called_from == null) {
    called_from = "empty string";
}
if (called_from.equalsIgnoreCase("add")) {
    // do whatever
} else {
    // do whatever
}

That way, if called_from is null, it'll execute the else part of your if statement.

I do this to make sure they remember to print landscape, which is necessary for a lot of pages on a lot of printers.

<a href="javascript:alert('Please be sure to set your printer to Landscape.');window.print();">Print Me...</a>

or

<body onload="alert('Please be sure to set your printer to Landscape.');window.print();">
etc.
</body>

With negative lookahead, regular expression can match something not contains specific pattern. This is answered and explained by Bart Kiers. Great explanation!

However, with Bart Kiers' answer, the lookahead part will test 1 to 4 characters ahead while matching any single character. We can avoid this and let the lookahead part check out the whole text, ensure there is no 'hede', and then the normal part (.*) can eat the whole text all at one time.

Here is the improved regex:

/^(?!.*?hede).*$/

Note the (*?) lazy quantifier in the negative lookahead part is optional, you can use (*) greedy quantifier instead, depending on your data: if 'hede' does present and in the beginning half of the text, the lazy quantifier can be faster; otherwise, the greedy quantifier be faster. However if 'hede' does not present, both would be equal slow.

Here is the demo code.

For more information about lookahead, please check out the great article: Mastering Lookahead and Lookbehind.

Also, please check out RegexGen.js, a JavaScript Regular Expression Generator that helps to construct complex regular expressions. With RegexGen.js, you can construct the regex in a more readable way:

var _ = regexGen;

var regex = _(
    _.startOfLine(),             
    _.anything().notContains(       // match anything that not contains:
        _.anything().lazy(), 'hede' //   zero or more chars that followed by 'hede',
                                    //   i.e., anything contains 'hede'
    ), 
    _.endOfLine()
);

This will work. Link to your SVG using the following pattern:

https://cdn.rawgit.com/<repo-owner>/<repo>/<branch>/path/to.svg

The downside is hardcoding the owner and repo in the path, meaning the svg will break if either of those are renamed.

The bash manpage says that the variable OSTYPE stores the name of the operation system:

• Login to your iPhone provisioning portal through developer.apple.com
• Add the UDID in devices
• Go to Provisioning Profile sections. Click on your provisioning profile, click on Edit.
• In Device section select your added device and generate provisioning certificate again.
• Download it and double click. It will automatically added in your Xcode.
• To check UDID present in .ipa file or not. Generate .ipa file and upload on diawi.com, get diawi link and hit on Safari browser. You can check their how many UDID are integrated in generated .ipa.

If you want to make multiple operation use

Well, here's an example for overloaded constructors.

public class Employee
{
   private String name;
   private int age;

   public Employee()
   {
      System.out.println("We are inside Employee() constructor");
   }

   public Employee(String name)
   {
      System.out.println("We are inside Employee(String name) constructor");
      this.name = name;
   }

   public Employee(String name, int age)
   {
      System.out.println("We are inside Employee(String name, int age) constructor");
      this.name = name;
      this.age = age;
   }

   public Employee(int age)
   {
      System.out.println("We are inside Employee(int age) constructor");
      this.age = age; 
   }

   public String getName()
   {
      return name;
   }

   public void setName(String name)
   {
      this.name = name;
   }

   public int getAge()
   {
      return age;
   }

   public void setAge(int age)
   {
      this.age = age;
   }
}

In the above example you can see overloaded constructors. Name of the constructors is same but each constructors has different parameters.

Here are some resources which throw more light on constructor overloading in java,

Here's my super cool version BECAUSE IT HAS A PROGRESS BAR :-)

Which is a completely useless feature, I know, but it still looks cool \m/ \m/

$webclient = New-Object System.Net.WebClient
Register-ObjectEvent -InputObject $webclient -EventName "UploadProgressChanged" -Action { Write-Progress -Activity "Upload progress..." -Status "Uploading" -PercentComplete $EventArgs.ProgressPercentage } > $null

$File = "filename.zip"
$ftp = "ftp://user:password@server/filename.zip"
$uri = New-Object System.Uri($ftp)
try{
    $webclient.UploadFileAsync($uri, $File)
}
catch  [Net.WebException]
{
    Write-Host $_.Exception.ToString() -foregroundcolor red
}
while ($webclient.IsBusy) { continue }

PS. Helps a lot, when I'm wondering "did it stop working, or is it just my slow ASDL connection?"

Assume s = socket.socket() The server can be bound by following methods: Method 1:

host = socket.gethostname()
s.bind((host, port))

Method 2:

host = socket.gethostbyname("localhost")  #Note the extra letters "by"
s.bind((host, port))

Method 3:

host = socket.gethostbyname("192.168.1.48")
s.bind((host, port))

If you do not exactly use same method on the client side, you will get the error: socket.error errno 111 connection refused.

So, you have to use on the client side exactly same method to get the host, as you do on the server. For example, in case of client, you will correspondingly use following methods:

Method 1:

host = socket.gethostname() 
s.connect((host, port))

Method 2:

host = socket.gethostbyname("localhost") # Get local machine name
s.connect((host, port))

Method 3:

host = socket.gethostbyname("192.168.1.48") # Get local machine name
s.connect((host, port))

Hope that resolves the problem.

Please check the following file

%SystemRoot%\system32\drivers\etc\host

The line which bind the host name with ip is probably missing a line which bind them togather

127.0.0.1  localhost

If the given line is missing. Add the line in the file

Could you also check your MySQL database's user table and tell us the host column value for the user which you are using. You should have user privilege for both the host "127.0.0.1" and "localhost" and use % as it is a wild char for generic host name.

$array = array("Jonathan","Sampson");

foreach($array as $value) {
  print $value;
}

or

$length = count($array);
for ($i = 0; $i < $length; $i++) {
  print $array[$i];
}

raw_input returns a string (a sequence of characters). In Python, multiplying a string and a float makes no defined meaning (while multiplying a string and an integer has a meaning: "AB" * 3 is "ABABAB"; how much is "L" * 3.14 ? Please do not reply "LLL|"). You need to parse the string to a numerical value.

You might want to try:

salesAmount = float(raw_input("Insert sale amount here\n"))

use Result Rows.
row() method returns a single result row.

$id = $this 
    -> db
    -> select('id')
    -> where('email', $email)
    -> limit(1)
    -> get('users')
    -> row();

then, you can simply use as you want. :)

echo "ID is" . $id;

You are implementing LocationListener in your activity MainActivity. The call for concurrent location updates will therefor be like this:

mLocationClient.requestLocationUpdates(mLocationRequest, this);

Be sure that the LocationListener you're implementing is from the google api, that is import this:

import com.google.android.gms.location.LocationListener;

and not this:

import android.location.LocationListener;

and it should work just fine.

It's also important that the LocationClient really is connected before you do this. I suggest you don't call it in the onCreate or onStart methods, but in onResume. It is all explained quite well in the tutorial for Google Location Api: https://developer.android.com/training/location/index.html

It's a choice (from browser devs or W3C, I can't find any W3C specification about styling select options though) not allowing to style select options.

I suspect this would be to keep consistency with native choice lists.
(think about mobile devices for example).

3 solutions come to my mind:

• Use Select2 which actually converts your selects into uls (allowing many things)
• Split your selects into multiple in order to group values
• Split into optgroup

• F# Has Better Performance than C# in Math
• You could use F# projects in the same solution with C# (and call from one to another)
• F# is really good for complex algorithmic programming, financial and scientific applications
• F# logically is really good for the parallel execution (it is easier to make F# code execute on parallel cores, than C#)

WHERE dates BETWEEN (convert(datetime, '2012-12-12',110) AND (convert(datetime, '2012-12-12',110))

I'm going to add some updated info and references to @max-malysh's excellent answer above.

In short, if you do something on the master, it needs to be replicated on the slave. Postgres uses WAL records for this, which are sent after every logged action on the master to the slave. The slave then executes the action and the two are again in sync. In one of several scenarios, you can be in conflict on the slave with what's coming in from the master in a WAL action. In most of them, there's a transaction happening on the slave which conflicts with what the WAL action wants to change. In that case, you have two options:

1. Delay the application of the WAL action for a bit, allowing the slave to finish its conflicting transaction, then apply the action.
2. Cancel the conflicting query on the slave.

We're concerned with #1, and two values:

• max_standby_archive_delay - this is the delay used after a long disconnection between the master and slave, when the data is being read from a WAL archive, which is not current data.
• max_standby_streaming_delay - delay used for cancelling queries when WAL entries are received via streaming replication.

Generally, if your server is meant for high availability replication, you want to keep these numbers short. The default setting of 30000 (milliseconds if no units given) is sufficient for this. If, however, you want to set up something like an archive, reporting- or read-replica that might have very long-running queries, then you'll want to set this to something higher to avoid cancelled queries. The recommended 900s setting above seems like a good starting point. I disagree with the official docs on setting an infinite value -1 as being a good idea--that could mask some buggy code and cause lots of issues.

The one caveat about long-running queries and setting these values higher is that other queries running on the slave in parallel with the long-running one which is causing the WAL action to be delayed will see old data until the long query has completed. Developers will need to understand this and serialize queries which shouldn't run simultaneously.

For the full explanation of how max_standby_archive_delay and max_standby_streaming_delay work and why, go here.

You can always simply add an alert() prompt anywhere in a function. Especially useful for knowing if a function was called, if a function completed or where a function fails.

alert('start of function x');
alert('end of function y');
alert('about to call function a');
alert('returned from function b');

You get the idea.

To actually resolve the issue I used the following command to stage all my files to the commit.

$ git add .
$ git commit -m 'Your message here'
$ git push origin master

The problem I had was that the -u command in git add didn't actually add the new files and the git add -A command wasn't supported on my installation of git. Thus as mentioned in this thread the commit I was trying to stage was empty.

As it answers my original question, I have accepted doc_180's answer, but if someone runs into this problem again, I will answer the 2nd half of my question as well:

The NullPointerError I described had nothing to do with the List itself, but with its content!

The "MyClass" class didn't have a "no args" constructor, and neither had its superclass one. Once I added a simple "MyClass()" constructor to MyClass and its superclass, everything worked fine, including the List serialization and deserialization as suggested by doc_180.

The alt attribute is defined in a set of tags (namely, img, area and optionally for input and applet) to allow you to provide a text equivalent for the object.

A text equivalent brings the following benefits to your web site and its visitors in the following common situations:

• nowadays, Web browsers are available in a very wide variety of platforms with very different capacities; some cannot display images at all or only a restricted set of type of images; some can be configured to not load images. If your code has the alt attribute set in its images, most of these browsers will display the description you gave instead of the images
• some of your visitors cannot see images, be they blind, color-blind, low-sighted; the alt attribute is of great help for those people that can rely on it to have a good idea of what's on your page
• search engine bots belong to the two above categories: if you want your website to be indexed as well as it deserves, use the alt attribute to make sure that they won't miss important sections of your pages.

Title Attribute

The objective of this technique is to provide context sensitive help for users as they enter data in forms by providing the help information in a title attribute. The help may include format information or examples of input.

Example 1: A pulldown menu that limits the scope of a search
A search form uses a pulldown menu to limit the scope of the search. The pulldown menu is immediately adjacent to the text field used to enter the search term. The relationship between the search field and the pulldown menu is clear to users who can see the visual design, which does not have room for a visible label. The title attribute is used to identify the select menu. The title attribute can be spoken by screen readers or displayed as a tool tip for people using screen magnifiers.

<label for="searchTerm">Search for:</label>
<input id="searchTerm" type="text" size="30" value="" name="searchTerm">
<select title="Search in" id="scope">
    ...
</select> 

Example 2: Input fields for a phone number
A Web page contains controls for entering a phone number in the United States, with three fields for area code, exchange, and last four digits.

<fieldset>
    <legend>Phone number</legend>
    <input id="areaCode" name="areaCode" title="Area Code" type="text" size="3" value="" >
    <input id="exchange" name="exchange" title="First three digits of phone number" type="text" size="3" value="" >
    <input id="lastDigits" name="lastDigits" title="Last four digits of phone number" type="text" size="4" value="" >
</fieldset> 

Example 3: A Search Function A Web page contains a text field where the user can enter search terms and a button labeled "Search" for performing the search. The title attribute is used to identify the form control and the button is positioned right after the text field so that it is clear to the user that the text field is where the search term should be entered.

<input type="text" title="Type search term here"/> <input type="submit" value="Search"/>

Example 4: A data table of form controls
A data table of form controls needs to associate each control with the column and row headers for that cell. Without a title (or off-screen LABEL) it is difficult for non-visual users to pause and interrogate for corresponding row/column header values using their assistive technology while tabbing through the form.

For example, a survey form has four column headers in first row: Question, Agree, Undecided, Disagree. Each following row contains a question and a radio button in each cell corresponding to answer choice in the three columns. The title attribute for every radio button is a concatenation of the answer choice (column header) and the text of the question (row header) with a hyphen or colon as a separator.

Img Element

Allowed attributes mentioned at MDN.

• alt
• crossorigin
• decoding
• height
• importance (experimental api)
• intrinsicsize (experimental api)
• ismap
• referrerpolicy (experimental api)
• src
• srcset
• width
• usemap

As you can see title attribute is not allowed inside img element. I would use alt attribute and if requires I would use CSS (Example: pseudo class :hover) instead of title attribute.

Here is how i resolved this:

1 - create a Field Variable like: private Menu mMenuItem;

2 - override the method invalidateOptionsMenu():

@Override
public void invalidateOptionsMenu() {
    super.invalidateOptionsMenu();
}

3 - call the method invalidateOptionsMenu() in your onCreate()

4 - add mMenuItem = menu in your onCreateOptionsMenu(Menu menu) like this:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.webview_menu, menu);
    mMenuItem = menu;
    return super.onCreateOptionsMenu(menu);
}

5 - in the method onOptionsItemSelected(MenuItem item) change the icon you want like this:

 @Override
public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()){

        case R.id.R.id.action_settings:
            mMenuItem.getItem(0).setIcon(R.drawable.ic_launcher); // to change the fav icon
            //Toast.makeText(this, " " + mMenuItem.getItem(0).getTitle(), Toast.LENGTH_SHORT).show(); <<--- this to check if the item in the index 0 is the one you are looking for
            return true;
    }
    return super.onOptionsItemSelected(item);
}

For starters:

<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.

This would be the optimal solution:

<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Shog9 is right that this doesn't make all that much sense to ask, since an object could be referred to by multiple variables. If you don't really care about that, and all you want is to find the name of one of the global variables that refers to that object, you could do the following hack:

function myClass() { 
  this.myName = function () { 
    // search through the global object for a name that resolves to this object
    for (var name in this.global) 
      if (this.global[name] == this) 
        return name 
  } 
}
// store the global object, which can be referred to as this at the top level, in a
// property on our prototype, so we can refer to it in our object's methods
myClass.prototype.global = this
// create a global variable referring to an object
var myVar = new myClass()
myVar.myName() // returns "myVar"

Note that this is an ugly hack, and should not be used in production code. If there is more than one variable referring to an object, you can't tell which one you'll get. It will only search the global variables, so it won't work if a variable is local to a function. In general, if you need to name something, you should pass the name in to the constructor when you create it.

edit: To respond to your clarification, if you need to be able to refer to something from an event handler, you shouldn't be referring to it by name, but instead add a function that refers to the object directly. Here's a quick example that I whipped up that shows something similar, I think, to what you're trying to do:

function myConstructor () {
  this.count = 0
  this.clickme = function () {
    this.count += 1
    alert(this.count)
  }

  var newDiv = document.createElement("div")
  var contents = document.createTextNode("Click me!")

  // This is the crucial part. We don't construct an onclick handler by creating a
  // string, but instead we pass in a function that does what we want. In order to
  // refer to the object, we can't use this directly (since that will refer to the 
  // div when running event handler), but we create an anonymous function with an 
  // argument and pass this in as that argument.
  newDiv.onclick = (function (obj) { 
    return function () {
      obj.clickme()
    }
  })(this)

  newDiv.appendChild(contents)
  document.getElementById("frobnozzle").appendChild(newDiv)

}
window.onload = function () {
  var myVar = new myConstructor()
}

var string = "Hello";
var str = string.substring(0, string.length-1);
alert(str);

Use the pandas idxmax function. It's straightforward:

>>> import pandas
>>> import numpy as np
>>> df = pandas.DataFrame(np.random.randn(5,3),columns=['A','B','C'])
>>> df
          A         B         C
0  1.232853 -1.979459 -0.573626
1  0.140767  0.394940  1.068890
2  0.742023  1.343977 -0.579745
3  2.125299 -0.649328 -0.211692
4 -0.187253  1.908618 -1.862934
>>> df['A'].argmax()
3
>>> df['B'].argmax()
4
>>> df['C'].argmax()
1

• Alternatively you could also use numpy.argmax, such as numpy.argmax(df['A']) -- it provides the same thing, and appears at least as fast as idxmax in cursory observations.

• idxmax() returns indices labels, not integers.

  • Example': if you have string values as your index labels, like rows 'a' through 'e', you might want to know that the max occurs in row 4 (not row 'd').
  • if you want the integer position of that label within the Index you have to get it manually (which can be tricky now that duplicate row labels are allowed).

HISTORICAL NOTES:

• idxmax() used to be called argmax() prior to 0.11
• argmax was deprecated prior to 1.0.0 and removed entirely in 1.0.0
• back as of Pandas 0.16, argmax used to exist and perform the same function (though appeared to run more slowly than idxmax).
  • argmax function returned the integer position within the index of the row location of the maximum element.
  • pandas moved to using row labels instead of integer indices. Positional integer indices used to be very common, more common than labels, especially in applications where duplicate row labels are common.

For example, consider this toy DataFrame with a duplicate row label:

In [19]: dfrm
Out[19]: 
          A         B         C
a  0.143693  0.653810  0.586007
b  0.623582  0.312903  0.919076
c  0.165438  0.889809  0.000967
d  0.308245  0.787776  0.571195
e  0.870068  0.935626  0.606911
f  0.037602  0.855193  0.728495
g  0.605366  0.338105  0.696460
h  0.000000  0.090814  0.963927
i  0.688343  0.188468  0.352213
i  0.879000  0.105039  0.900260

In [20]: dfrm['A'].idxmax()
Out[20]: 'i'

In [21]: dfrm.iloc[dfrm['A'].idxmax()]  # .ix instead of .iloc in older versions of pandas
Out[21]: 
          A         B         C
i  0.688343  0.188468  0.352213
i  0.879000  0.105039  0.900260

So here a naive use of idxmax is not sufficient, whereas the old form of argmax would correctly provide the positional location of the max row (in this case, position 9).

This is exactly one of those nasty kinds of bug-prone behaviors in dynamically typed languages that makes this sort of thing so unfortunate, and worth beating a dead horse over. If you are writing systems code and your system suddenly gets used on some data sets that are not cleaned properly before being joined, it's very easy to end up with duplicate row labels, especially string labels like a CUSIP or SEDOL identifier for financial assets. You can't easily use the type system to help you out, and you may not be able to enforce uniqueness on the index without running into unexpectedly missing data.

So you're left with hoping that your unit tests covered everything (they didn't, or more likely no one wrote any tests) -- otherwise (most likely) you're just left waiting to see if you happen to smack into this error at runtime, in which case you probably have to go drop many hours worth of work from the database you were outputting results to, bang your head against the wall in IPython trying to manually reproduce the problem, finally figuring out that it's because idxmax can only report the label of the max row, and then being disappointed that no standard function automatically gets the positions of the max row for you, writing a buggy implementation yourself, editing the code, and praying you don't run into the problem again.

Watch out if you want to retrieve a boolean value from a hidden field!

For example:

<input type="hidden" id="SomeBoolean" value="False"/>

(An input like this will be rendered by ASP MVC if you use @Html.HiddenFor(m => m.SomeBoolean).)

Then the following will return a string 'False', not a JS boolean!

var notABool = $('#SomeBoolean').val();

If you want to use the boolean for some logic, use the following instead:

var aBool = $('#SomeBoolean').val() === 'True';
if (aBool) { /* ...*/ }

open your browser,check whether Tomcat homepage is visible by below command.

Here is a function that will do that.

CREATE FUNCTION count_str(haystack TEXT, needle VARCHAR(32))

  BEGIN
    RETURN ROUND((CHAR_LENGTH(haystack) - CHAR_LENGTH(REPLACE(haystack, needle, ""))) / CHAR_LENGTH(needle));
  END;

If you are using RecyclerView-23.2.1 or later. Following solution will work just fine:

In your layout add RecyclerView like this:

<android.support.v7.widget.RecyclerView
        android:id="@+id/review_list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:scrollbars="vertical" />

And in your java file:

RecyclerView mRecyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
LinearLayoutManager layoutManager=new LinearLayoutManager(getContext());
layoutManager.setAutoMeasureEnabled(true);
mRecyclerView.setLayoutManager(layoutManager);
mRecyclerView.setHasFixedSize(true);
mRecyclerView.setAdapter(new YourListAdapter(getContext()));

Here layoutManager.setAutoMeasureEnabled(true); will do the trick.

'svn delete' works against repository content, not against the repository itself. for doing repository maintenance (like completely deleting one) you should use svnadmin. However, there's a reason why svnadmin doesn't have a 'delete' subcommand. You can just

rm -rf $REPOS_PATH

on the svn server,

where $REPOS_PATH is the path you used to create your repository with

svnadmin create $REPOS_PATH

It seems your question is very much older. But I just saw it. I searched(not in google) and found My Answer.

So I am writing its solution so that others may get help from it.

Here is my solution.

Unlike the other answers, you don't need to setup environments.

all you need is just to write php index.php if index.php is your file name.

then you will see that, the file compiled and showing it's desired output.

Wow, I had the same problem, but a line of code resolved my problem. I wrote

$last_child_topic.find( "*" ).prop( "disabled", true );
$last_child_topic.find( "option" ).prop( "disabled", false );   //This seems to work on mine

I send the form to a php script then it prints the correct value for each options while it was "null" before.

Tell me if this works out. I wonder if this only works on mine somehow.

If an abstract class is appropriate for your implementation, test (as suggested above) a derived concrete class. Your assumptions are correct.

To avoid future confusion, be aware that this concrete test class is not a mock, but a fake.

In strict terms, a mock is defined by the following characteristics:

• A mock is used in place of each and every dependency of the subject class being tested.
• A mock is a pseudo-implementation of an interface (you may recall that as a general rule, dependencies should be declared as interfaces; testability is one primary reason for this)
• Behaviors of the mock's interface members -- whether methods or properties -- are supplied at test-time (again, by use of a mocking framework). This way, you avoid coupling of the implementation being tested with the implementation of its dependencies (which should all have their own discrete tests).

This is a warning related to the fact that most JavaScript frameworks (jQuery, Angular, YUI, Bootstrap...) offer backward support for old-nasty-most-hated Internet Explorer starting from IE8 down to IE6 :/

One day that backward compatibility support will be dropped (for IE8/7/6 since IE9 deals with it), and you will no more see this warning (and other IEish bugs)..

It's a question of time (now IE8 has 10% worldwide share, once it reaches 1% it is DEAD), meanwhile, just ignore the warning and stay zen :)

So, eventually I did that thing that all developers hate doing. I went and checked the server log files and found a report of a syntax error in line n.

There's more then one way to do this with DateTime which was introduced in PHP 5.2. Unlike using strtotime() this will account for daylight savings time and leap year.

$datetime = new DateTime('2013-01-29');
$datetime->modify('+1 day');
echo $datetime->format('Y-m-d H:i:s');

// Available in PHP 5.3

$datetime = new DateTime('2013-01-29');
$datetime->add(new DateInterval('P1D'));
echo $datetime->format('Y-m-d H:i:s');

// Available in PHP 5.4

echo (new DateTime('2013-01-29'))->add(new DateInterval('P1D'))->format('Y-m-d H:i:s');

// Available in PHP 5.5

$start = new DateTimeImmutable('2013-01-29');
$datetime = $start->modify('+1 day');
echo $datetime->format('Y-m-d H:i:s');

jQuery (1.4.2) gets confused if you have any form elements named "action". You can get around this by using the DOM attribute methods or simply avoid having form elements named "action".

<form action="foo">
  <button name="action" value="bar">Go</button>
</form>

<script type="text/javascript">
  $('form').attr('action', 'baz'); //this fails silently
  $('form').get(0).setAttribute('action', 'baz'); //this works
</script>

You really want to do this

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

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

Russian Edition offers CSV, CSV (Macintosh) and CSV (DOS).

When saving in plain CSV, it uses windows-1251.

I just tried to save French word Résumé along with the Russian text, it saved it in HEX like 52 3F 73 75 6D 3F, 3F being the ASCII code for question mark.

When I opened the CSV file, the word, of course, became unreadable (R?sum?)

This is happening because your PHP code is getting executed before the form gets posted.

To avoid this wrap your PHP code in following if statement and it will handle the rest no need to set if statements for each variables

       if(isset($_POST) && array_key_exists('name_of_your_submit_input',$_POST))
        {
             //process PHP Code
        }
        else
        {
             //do nothing
         }

Based on the answer of @AlokThakur (thanks!):

    return_value = os.system(command)
    # Calculate the return value code
    return_value = int(bin(return_value).replace("0b", "").rjust(16, '0')[:8], 2)
    if return_value != 0:
        raise RuntimeError(f'The system command\n{command}\nexited with return code {return_value}')

You may want to use the "xcode-select" command in terminal to switch between the different Xcode version in the installed folders.

If you go to the Flat file connection manager under Advanced and Look at the "OutputColumnWidth" description's ToolTip It will tell you that Composit characters may use more spaces. So the "é" in "Société" most likely occupies more than one character.

EDIT: Here's something about it: http://en.wikipedia.org/wiki/Precomposed_character

Your logic is correct but you have 2 mistakes apparently everyone missed:

just change if(Number(i) = 'NaN') to if(Number(i) == NaN)

NaN is a constant and you should use double equality signs to compare, a single one is used to assign values to variables.

Get the dictionary from enum.

{
    return Enum.GetValues(enumType)
    .Cast<object>()

    Type type = en.GetType();
    MemberInfo[] memInfo = type.GetMember(en.ToString());

    {
        object[] attrs = memInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), false);
        if (attrs != null && attrs.Length > 0)
            return ((DescriptionAttribute)attrs[0]).Description;
    }
    return en.ToString();
}

You can run conda install --file requirements.txt instead of the loop, but there is no target directory in conda install. conda install installs a list of packages into a specified conda environment.

Short Answer

To copy myfile.txt to /foo/bar/myfile.txt, use:

mkdir -p /foo/bar && cp myfile.txt $_

How does this work?

There's a few components to this, so I'll cover all the syntax step by step.

The mkdir utility, as specified in the POSIX standard, makes directories. The -p argument, per the docs, will cause mkdir to

Create any missing intermediate pathname components

meaning that when calling mkdir -p /foo/bar, mkdir will create /foo and /foo/bar if /foo doesn't already exist. (Without -p, it will instead throw an error.

The && list operator, as documented in the POSIX standard (or the Bash manual if you prefer), has the effect that cp myfile.txt $_ only gets executed if mkdir -p /foo/bar executes successfully. This means the cp command won't try to execute if mkdir fails for one of the many reasons it might fail.

Finally, the $_ we pass as the second argument to cp is a "special parameter" which can be handy for avoiding repeating long arguments (like file paths) without having to store them in a variable. Per the Bash manual, it:

expands to the last argument to the previous command

In this case, that's the /foo/bar we passed to mkdir. So the cp command expands to cp myfile.txt /foo/bar, which copies myfile.txt into the newly created /foo/bar directory.

Note that $_ is not part of the POSIX standard, so theoretically a Unix variant might have a shell that doesn't support this construct. However, I don't know of any modern shells that don't support $_; certainly Bash, Dash, and zsh all do.

A final note: the command I've given at the start of this answer assumes that your directory names don't have spaces in. If you're dealing with names with spaces, you'll need to quote them so that the different words aren't treated as different arguments to mkdir or cp. So your command would actually look like:

mkdir -p "/my directory/name with/spaces" && cp "my filename with spaces.txt" "$_"

I agree with MarsPeople regarding loading libraries in the wrong order. My example is from working with owl.carousel.

I got the same error when importing jquery after owl.carousel:

<script src="owl.carousel.js"></script>
<script src="jquery-3.1.1.min.js"></script>

and fixed it by importing jquery before owl.carousel:

<script src="jquery-3.1.1.min.js"></script>
<script src="owl.carousel.js"></script>

I use the following method in my JavaFX applications.

You can force gcc to output directly to assembly code by adding the -S switch

gcc -S hello.c

Shared Preferences is so easy to learn, so take a look on this simple tutorial about sharedpreference

import android.os.Bundle;
import android.preference.PreferenceActivity;

    public class UserSettingActivity extends PreferenceActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

      addPreferencesFromResource(R.xml.settings);

    }
}

A class that takes a required dependency as a constructor argument can only be instantiated if that argument is provided (you should have a guard clause to make sure the argument is not null.) A constructor therefore enforces the dependency requirement whether or not you're using Spring, making it container-agnostic.

If you use setter injection, the setter may or may not be called, so the instance may never be provided with its dependency. The only way to force the setter to be called is using @Required or @Autowired , which is specific to Spring and is therefore not container-agnostic.

So to keep your code independent of Spring, use constructor arguments for injection.

Update: Spring 4.3 will perform implicit injection in single-constructor scenarios, making your code more independent of Spring by potentially not requiring an @Autowired annotation at all.

You must remove alpha channels when uploading a photo to iTunes Connect.

You can do this by Preview, Photos App (old iPhoto), Pixelmator, Adobe Photoshop and GIMP.

Preview

1. Open the photo in Preview (if the photo is in your photo album in Photos app (the old iPhoto), then simply drag it from the album to desktop. Then control-click (right-click when mouse) the duplicated photo and select Preview.app under Open With menu).

2. Select Export… under File menu, and after selecting the destination, uncheck Alpha at the bottom, and click Export.

   

   

Pixelmator

1. Open the image in Pixelmator, without creating a new Pixelmator file. Just drag the photo to the Pixelmator window.

2. From Share menu, click Export for Web…

   

3. In the top bar, deselect Transparency.

4. Click Next and then save the new file somewhere.

Finally, upload the new photo to iTunes Connect.

GIMP

1. Open the photo in GIMP.

2. Open the Layer menu.

3. Under Transparency, click Remove Alpha Channel.

4. Save the photo.

Adobe Photoshop

1. Open the photo in Adobe Photoshop.

2. Under Layer menu, click Layer Mask and then From Transparency.

3. Delete the layer mask by right-clicking on the mask in the Layer panel and selecting Delete Layer Mask.

I don't think desc takes an na.rm argument... I'm actually surprised it doesn't throw an error when you give it one. If you just want to remove NAs, use na.omit (base) or tidyr::drop_na:

outcome.df %>%
  na.omit() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

library(tidyr)
outcome.df %>%
  drop_na() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

If you only want to remove NAs from the HeartAttackDeath column, filter with is.na, or use tidyr::drop_na:

outcome.df %>%
  filter(!is.na(HeartAttackDeath)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

outcome.df %>%
  drop_na(HeartAttackDeath) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

As pointed out at the dupe, complete.cases can also be used, but it's a bit trickier to put in a chain because it takes a data frame as an argument but returns an index vector. So you could use it like this:

outcome.df %>%
  filter(complete.cases(.)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

For Windows, CaptureStackBackTrace() is also an option, which requires less preparation code on the user's end than StackWalk64() does. (Also, for a similar scenario I had, CaptureStackBackTrace() ended up working better (more reliably) than StackWalk64().)

Explanation internal working on this error

You are getting this error because after instantiation the container is trying to assign same object to both classes as class name is same irrespective of different packages......thats why error says non compatible bean definition of same name ..

Actually how it works internally is--->>>>.

pkg test1; …. @RestController class Test{}

pkg test2; …. @RestController class Test{}

First container will get class Test and @RestController indicates it to instantiate as…test = new Test(); and it won’t instantiate twice After instantiating container will provide a reference variable test(same as class name) to both the classes and while it provide test reference To second class it gets non compatible bean definition of same name ……

Solution—>>>>

Assign a refrence name to both rest controller so that container won’t instantiate with default name and instantiate saperately for both classes irrespective Of same name

For example——>>>

pkg test1; …. @RestController(“test1”) class Test{}

pkg test2; …. @RestController(“test2”) class Test{}

Note:The same will work with @Controller,@Service,@Repository etc..

Note: if you are creating reference variable at class level then you can also annotate it with @Qualifier("specific refrence name") for example @Autowired @Qualifier("test1") Test test;

After wasting an hour on complex and hacky solutions, I've found both simple and valid solution for commenting my bulky dependencies section in package.json. Just like this:

{
  "name": "package name",
  "version": "1.0",
  "description": "package description",
  "scripts": {
    "start": "npm install && node server.js"
  },
  "scriptsComments": {
    "start": "Runs development build on a local server configured by server.js"
  },
  "dependencies": {
    "ajv": "^5.2.2"
  },
  "dependenciesComments": {
    "ajv": "JSON-Schema Validator for validation of API data"
  }
}

When sorted the same way, it's now very easy for me to track these pairs of dependencies/comments either in Git commit diffs or in an editor while working with file package.json.

And no extra tools are involved, just plain and valid JSON.

If you are just trying to figure out what a malware does, it might be much easier to run it under something like the free tool Process Monitor which will report whenever it tries to access the filesystem, registry, ports, etc...

Also, using a virtual machine like the free VMWare server is very helpful for this kind of work. You can make a "clean" image, and then just go back to that every time you run the malware.

Your primary question has been answered above. I just wanted to point out that the regex you're using has a bug. It will also succeed on foo-domain.com which is not a subdomain of domain.com

What you really want is this:

/(^|\.)domain\.com$/

The best way is:

1. Right-click on the output panel.
2. Choose view frame source, then the whole code will appear.

After that you can copy that code, and paste it in your computer.

Double quotes option helped me

SET QUOTED_IDENTIFIER OFF;
insert into my_table values("hi, my name's tim.");
SET QUOTED_IDENTIFIER ON;

Consider using a Spinner instead of a Number Picker in a Dialog. It's not exactly what was asked for, but it's much easier to implement, more contextual UI design, and should fulfill most use cases. The equivalent code for a Spinner is:

Spinner picker = new Spinner(this);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_spinner_item, yourStringList);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
picker.setAdapter(adapter);

For null or undefined value error, Just add this line to attributes : ,columnDefs: [ { "defaultContent": "-", "targets": "_all" } ]

Example :

oTable = $("#bigtable").dataTable({
  columnDefs: [{
    "defaultContent": "-",
    "targets": "_all"
  }]
});

The alert box will not show again, any empty values will be replaced with what you specified.

Although this post is post is tagged for Windows, it is relevant question on OS X that I have not seen answers for elsewhere. Here are steps to create a self-signed cert for localhost on OS X:

# Use 'localhost' for the 'Common name'
openssl req -x509 -sha256 -nodes -newkey rsa:2048 -days 365 -keyout localhost.key -out localhost.crt

# Add the cert to your keychain
open localhost.crt

In Keychain Access, double-click on this new localhost cert. Expand the arrow next to "Trust" and choose to "Always trust". Chrome and Safari should now trust this cert. For example, if you want to use this cert with node.js:

var options = {
    key: fs.readFileSync('/path/to/localhost.key').toString(),
    cert: fs.readFileSync('/path/to/localhost.crt').toString(),
    ciphers: 'ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES256-SHA384',
    honorCipherOrder: true,
    secureProtocol: 'TLSv1_2_method'
};

var server = require('https').createServer(options, app);

Looks like it could be throwing the error on the empty data row, have you tried to just make sure itemDate isn't empty before you run the CDate() function? I think this might be your problem.

Not sure if this is a new thing, but with deployments it is possible to do it like this:

kubectl logs deployment/app1

According to the GCC page for C++11:

To enable C++0x support, add the command-line parameter -std=c++0x to your g++ command line. Or, to enable GNU extensions in addition to C++0x extensions, add -std=gnu++0x to your g++ command line. GCC 4.7 and later support -std=c++11 and -std=gnu++11 as well.

Did you compile with -std=gnu++0x ?

One of your tables has the same column name's which brings a confusion in the query as to which columns of the tables are you referring to. Copy this code and run it.

SELECT 
    v.VendorName, i.InvoiceID, iL.InvoiceSequence, iL.InvoiceLineItemAmount
FROM Vendors AS v
JOIN Invoices AS i ON (v.VendorID = .VendorID)
JOIN InvoiceLineItems AS iL ON (i.InvoiceID = iL.InvoiceID)
WHERE  
    I.InvoiceID IN
        (SELECT iL.InvoiceSequence 
         FROM InvoiceLineItems
         WHERE iL.InvoiceSequence > 1)
ORDER BY 
    V.VendorName, i.InvoiceID, iL.InvoiceSequence, iL.InvoiceLineItemAmount

As already stated, enum instances should be uppercase according to the docs on the Oracle website (http://docs.oracle.com/javase/tutorial/java/javaOO/enum.html).

However, while looking through a JavaEE7 tutorial on the Oracle website (http://www.oracle.com/technetwork/java/javaee/downloads/index.html), I stumbled across the "Duke's bookstore" tutorial and in a class (tutorial\examples\case-studies\dukes-bookstore\src\main\java\javaeetutorial\dukesbookstore\components\AreaComponent.java), I found the following enum definition:

private enum PropertyKeys {
    alt, coords, shape, targetImage;
}

According to the conventions, it should have looked like:

public enum PropertyKeys {
    ALT("alt"), COORDS("coords"), SHAPE("shape"), TARGET_IMAGE("targetImage");

    private final String val;

    private PropertyKeys(String val) {
        this.val = val;
    }

    @Override
    public String toString() {
        return val;
    }
}

So it seems even the guys at Oracle sometimes trade convention with convenience.

klass.instance_methods.include :method_name or "method_name", depending on the Ruby version I think.

select CONCAT(Name, '(',substr(occupation, 1, 1), ')') AS f1

(select count(occupation) AS counts, occupation, concat('There are a total of ' ,count(occupation) ,' ', lower(occupation),'s.') As str  from OCCUPATIONS group by occupation order by counts ASC, occupation ASC

Simple jquery to remove not selected options.

$('#your_dropdown_id option:not(:selected)').remove();

The concept of http location and disk location is different. What you need to do is:

1. for uploaded file summer.jpg
2. move that under a known (to the application) location to disk, e.g c:\images\summer.jpg
3. insert into db record representing the image with text summer.jpg
4. to display it use plain <img src="images/summer.jpg" />
5. you need something (e.g apache) that will serve c:\images\ under your application's /images. If you cannot do this then in step #2 you need to save somewhere under your web root, e.g c:\my-applications\demo-app\build\images

Iconv just writes the converted text to stdout. You have to use -o OUTPUTFILE.txt as an parameter or write stdout to a file. (iconv -f x -t z filename.txt > OUTPUTFILE.txt or iconv -f x -t z < filename.txt > OUTPUTFILE.txt in some iconv versions)

Synopsis

iconv -f encoding -t encoding inputfile

Description

The iconv program converts the encoding of characters in inputfile from one coded character set to another. 
**The result is written to standard output unless otherwise specified by the --output option.**

--from-code, -f encoding

Convert characters from encoding

--to-code, -t encoding

Convert characters to encoding

--list

List known coded character sets

--output, -o file

Specify output file (instead of stdout)

--verbose

Print progress information.

Follow below steps to do this or simply use apkToJava gem for this process, it even takes care of installing the required tools for it to work.

• convert apk file to zip
• unzip the file
• extract classes.dex from it
• use dex to jar to convert classes.dex into jar file
• use jadx gui to open the jar file as java source code

Redirect fd's

Output needs to be redirected with &>/dev/null which redirects both stderr and stdout to /dev/null and is a synonym of >/dev/null 2>/dev/null or >/dev/null 2>&1.

Parantheses

The best way is to use sh -c '( ( command ) & )' where command is anything.

ssh askapache 'sh -c "( ( nohup chown -R ask:ask /www/askapache.com &>/dev/null ) & )"'

Nohup Shell

You can also use nohup directly to launch the shell:

ssh askapache 'nohup sh -c "( ( chown -R ask:ask /www/askapache.com &>/dev/null ) & )"'

Nice Launch

Another trick is to use nice to launch the command/shell:

ssh askapache 'nice -n 19 sh -c "( ( nohup chown -R ask:ask /www/askapache.com &>/dev/null ) & )"'

Use the --force (-f) flag on your mysql import. Rather than stopping on the offending statement, MySQL will continue and just log the errors to the console.

For example:

mysql -u userName -p -f -D dbName < script.sql

This worked for me:

export class Hero{
   id: number;
   name: string;

   public Hero(i: number, n: string){
     this.id = 0;
     this.name = '';
   }
 }

and make sure you initialize as well selectedHero

selectedHero: Hero = new Hero();

I faced the same issue and solved using the below steps. Go to Windows->preferences->Editors->File Associations

Here click on Add then type .class click on OK

again click on Add then type .classwithoughtsource click on OK

Now you will be able to see JadClipse option under Java section in Windows->Preferences

Please provide the path of jad.exe file as shown below.

Path for Decompiler-C:\Users\ahr\Documents\eclipse-jee-galileo-SR2-win32\jad.exe Directory for temporary Files-C:\Users\ahr.net.sf.jadclipse

click on Apply

Now you should be able to see the classfiles in proper format.

• using: You are going to use it.
• namespace: To use what? A namespace.
• std: The std namespace (where features of the C++ Standard Library, such as string or vector, are declared).

After you write this instruction, if the compiler sees string it will know that you may be referring to std::string, and if it sees vector, it will know that you may be referring to std::vector. (Provided that you have included in your compilation unit the header files where they are defined, of course.)

If you don't write it, when the compiler sees string or vector it will not know what you are refering to. You will need to explicitly tell it std::string or std::vector, and if you don't, you will get a compile error.
