There is no portable function that allows to check if a key is hit and continue if not. This is always system dependent.

Solution for linux and other posix compliant systems:

Here, for Morgan Mattews's code provide kbhit() functionality in a way compatible with any POSIX compliant system. He uses the trick of desactivating buffering at termios level.

Solution for windows:

For windows, Microsoft offers _kbhit()

@Dirk Eddelbuettel: The basic idea is excellent but the code as shown can be improved. [Takes long to explain, hence a separate answer and not a comment.]

The hist() function by default draws plots, so you need to add the plot=FALSE option. Moreover, it is clearer to establish the plot area by a plot(0,0,type="n",...) call in which you can add the axis labels, plot title etc. Finally, I would like to mention that one could also use shading to distinguish between the two histograms. Here is the code:

set.seed(42)
p1 <- hist(rnorm(500,4),plot=FALSE)
p2 <- hist(rnorm(500,6),plot=FALSE)
plot(0,0,type="n",xlim=c(0,10),ylim=c(0,100),xlab="x",ylab="freq",main="Two histograms")
plot(p1,col="green",density=10,angle=135,add=TRUE)
plot(p2,col="blue",density=10,angle=45,add=TRUE)

And here is the result (a bit too wide because of RStudio :-) ):

Try / \([\s\S]*?\)/g

Where

(space) matches the character (space) literally

\( matches the character ( literally

[\s\S] matches any character (\s matches any whitespace character and \S matches any non-whitespace character)

*? matches between zero and unlimited times

\) matches the character ) literally

g matches globally

Code Example:

var str = "Hello, this is Mike (example)";
str = str.replace(/ \([\s\S]*?\)/g, '');
console.log(str);

.as-console-wrapper {top: 0}

To see what the problem is, when you get the cryptic error 0 go to ... | More Tools | Developer Tools (Ctrl+Shift+I) in Chrome (on the page giving the error)

Read the red text in the log to get the true error message. If there is too much in there, right-click and Clear Console, then do your last request again.

My first problem was, I was passing in Authorization headers to my own cross-domain web service for the browser for the first time.

I already had:

Access-Control-Allow-Origin: *

But not:

Access-Control-Allow-Methods: GET, POST, PUT, DELETE
Access-Control-Allow-Headers: Authorization

in the response header of my web service.

After I added that, my error zero was gone from my own web server, as well as when running the index.html file locally without a web server, but was still giving errors in code pen.

Back to ... | More Tools | Developer Tools while getting the error in codepen, and there is clearly explained: codepen uses https, so I cannot make calls to http, as the security is lower.

I need to therefore host my web service on https.

Knowing how to get the true error message - priceless!

Here are the few techniques I've heard of:

1. Use clone() if the class implements Cloneable. This API is a bit flawed in java and I never quite understood why clone is not defined in the interface, but in Object. Still, it might work.

2. Create a clone manually. If there is a constructor that accepts all parameters, it might be simple, e.g new User( user.ID, user.Age, ... ). You might even want a constructor that takes a User: new User( anotherUser ).

3. Implement something to copy from/to a user. Instead of using a constructor, the class may have a method copy( User ). You can then first snapshot the object backupUser.copy( user ) and then restore it user.copy( backupUser ). You might have a variant with methods named backup/restore/snapshot.

4. Use the state pattern.

5. Use serialization. If your object is a graph, it might be easier to serialize/deserialize it to get a clone.

That all depends on the use case. Go for the simplest.

EDIT

I also recommend to have a look at these questions:

• Clone() vs. Copy constructor
• How to properly override clone method

A field can be assigned to either the class or an instance of a class. By default fields are instance variables. By using static the field becomes a class variable, thus there is one and only one clock. If you make a changes in one place, it's visible everywhere. Instance varables are changed independently of one another.

I use:

delete $array[$index];

Perldoc delete.

I ran into the same problem.

I downloaded the 'popper.min.js' file from the CDN on the bootstrap website.

See here: https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js

Easier than compiling the project.

Important: You must include popper after jquery but BEFORE bootstrap.

The problem is with the way you are printing the Time data

java.util.Date utilDate = new java.util.Date();
java.sql.Timestamp sq = new java.sql.Timestamp(utilDate.getTime());
System.out.println(sa); //this will print the milliseconds as the toString() has been written in that format

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println(sdf.format(timestamp)); //this will print without ms

This is what we called Composite Formatting of the .NET Framework to convert the value of an object to its text representation and embed that representation in a string. The resulting string is written to the output stream.

The overloaded Console.WriteLine Method (String, Object)Writes the text representation of the specified object, followed by the current line terminator, to the standard output stream using the specified format information.

Validator::extend('phone', function($attribute, $value, $parameters, $validator) {
        return preg_match('%^(?:(?:\(?(?:00|\+)([1-4]\d\d|[1-9]\d?)\)?)?[\-\.\ \\\/]?)?((?:\(?\d{1,}\)?[\-\.\ \\\/]?){0,})(?:[\-\.\ \\\/]?(?:#|ext\.?|extension|x)[\-\.\ \\\/]?(\d+))?$%i', $value) && strlen($value) >= 10;
    });

Validator::replacer('phone', function($message, $attribute, $rule, $parameters) {
        return str_replace(':attribute',$attribute, ':attribute is invalid phone number');
    });

Usage

Insert this code in the app/Providers/AppServiceProvider.php to be booted up with your application.

This rule validates the telephone number against the given pattern above that i found after
long search it matches the most common mobile or telephone numbers in a lot of countries
This will allow you to use the phone validation rule anywhere in your application, so your form validation could be:

 'phone' => 'required|numeric|phone' 

Do you want compare VBA with VB-Classic (VB6..) or VB.NET?

VBA (Visual Basic for Applications) is a vb-classic-based script language embedded in Microsoft Office applications. I think it's language features are similar to those of VB5 (it just lacks some few builtin functions), but:

You have access to the office document you wrote the VBA-script for and so you can e.g.

• Write macros (=automated routines for little recurring tasks in your office-work)
• Define new functions for excel-cell-formula
• Process office data

Example: Set the value of an excel-cell

ActiveSheet.Cells("A1").Value = "Foo"

VBC and -.NET are no script languages. You use them to write standalone-applications with separate IDE's which you can't do with VBA (VBA-scripts just "exist" in Office)

VBA has nothing to do with VB.NET (they just have a similar syntax).

Given your representation, your function is as efficient as can be done. Of course, as noted by others (and as practiced in languages older than Lua), the solution to your real problem is to change representation. When you have tables and you want sets, you turn tables into sets by using the set element as the key and true as the value. +1 to interjay.

A blog post that I found useful: Understanding JavaScript Prototypes

You can mess with the __proto__ property of the Object.

var fooJSON = jQuery.parseJSON({"a":4, "b": 3});
fooJSON.__proto__ = Foo.prototype;

This allows fooJSON to inherit the Foo prototype.

I don't think this works in IE, though... at least from what I've read.

I had the issue where it wouldn't find the PayPal assembly and it was because I had named my solution PayPal. I'm sure this won't be the answer for anyone but thought I'd share it anyway: C# ASP.NET MVC PayPal not finding assembly

I used the following trick for the same problem. The good thing is it doesn't require any javascript.

CSS:

.body {
     margin: 0em;
}

.page {
    width: 100vw;
    height: 100vh;
    position: fixed;
    top: 0;
    left: -100vw;
    overflow-y: auto;
    z-index: 0;
    background-color: hsl(0,0%,100%);
}

  .page:target {
    left: 0vw;
    z-index: 1;
}

HTML:

<ul>
    <li>Click <a href="#one">here</a> for page 1</li>
    <li>Click <a href="#two">here</a> for page 2</li>
</ul>

<div class="page" id="one">
    Content of page 1 goes here.

    <ul>
        <li><a href="#">Back</a></li>
        <li><a href="#two">Page 2</a></li>
    </ul>
</div>

<div class="page" id="two">
    Content of page 2 goes here.

    <ul style="margin-bottom: 100vh;">
        <li><a href="#">Back</a></li>
        <li><a href="#one">Page 1</a></li>
    </ul>
</div>

See a JSFiddle.

Added advantage: as your url changes along, you can use it to link to specific pages. This is something the method won't let you do.

Hope this helps!

I had the same issue, the easiest way i found to insert the current date into a prepared statement is this one:

preparedStatement.setDate(1, new java.sql.Date(new java.util.Date().getTime()));

The primary flag seems to only work for vagrant ssh for me.

In the past I have used the following method to hack around the issue.

# stage box intended for configuration closely matching production if ARGV[1] == 'stage'     config.vm.define "stage" do |stage|         box_setup stage, \         "10.9.8.31", "deploy/playbook_full_stack.yml", "deploy/hosts/vagrant_stage.yml"     end end 

If a class type is not defined, you'll get a compiler error if you try to use the class, so in that sense you should have to check.

If you have an instance, and you want to ensure it's not null, simply check for null:

if (value != null)
{
    // it's not null. 
}

Assuming WinForms, the ForeColor property allows to change all the text in the TextBox (not just what you're about to add):

TextBox.ForeColor = Color.Red;

To only change the color of certain words, look at RichTextBox.

May be You are not registering the Controllers. Try below code:

Step 1. Write your own controller factory class ControllerFactory :DefaultControllerFactory by implementing defaultcontrollerfactory in models folder

  public class ControllerFactory :DefaultControllerFactory
    {
    protected override IController GetControllerInstance(RequestContext         requestContext, Type controllerType)
        {
            try
            {
                if (controllerType == null)
                    throw new ArgumentNullException("controllerType");

                if (!typeof(IController).IsAssignableFrom(controllerType))
                    throw new ArgumentException(string.Format(
                        "Type requested is not a controller: {0}",
                        controllerType.Name),
                        "controllerType");

                return MvcUnityContainer.Container.Resolve(controllerType) as IController;
            }
            catch
            {
                return null;
            }

        }
        public static class MvcUnityContainer
        {
            public static UnityContainer Container { get; set; }
        }
    }

Step 2:Regigster it in BootStrap: inBuildUnityContainer method

private static IUnityContainer BuildUnityContainer()
    {
      var container = new UnityContainer();

      // register all your components with the container here
      // it is NOT necessary to register your controllers

      // e.g. container.RegisterType<ITestService, TestService>();    
      //RegisterTypes(container);
      container = new UnityContainer();
      container.RegisterType<IProductRepository, ProductRepository>();


      MvcUnityContainer.Container = container;
      return container;
    }

Step 3: In Global Asax.

protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();

            WebApiConfig.Register(GlobalConfiguration.Configuration);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
            AuthConfig.RegisterAuth();
            Bootstrapper.Initialise();
            ControllerBuilder.Current.SetControllerFactory(typeof(ControllerFactory));

        }

And you are done

Please try the following code below:

//Here I am using a reader object to fetch data from database, along with sqlcommand onject (cmd).
//Once the data is loaded to the Datatable object (datatable) you can loop through it using the datatable.rows.count prop.

using (reader = cmd.ExecuteReader())
{
// Load the Data table object
  dataTable.Load(reader);
  if (dataTable.Rows.Count > 0)
  {
    DataColumn col = dataTable.Columns["YourColumnName"];  
    foreach (DataRow row in dataTable.Rows)
    {                                   
       strJsonData = row[col].ToString();
    }
  }
}

I am using the below format to test with a web server.

use -F 'json data'

Let's assume this JSON dict format:

{
    'comment': {
        'who':'some_one',
        'desc' : 'get it'
    }
}

Full example

curl -XPOST your_address/api -F comment='{"who":"some_one", "desc":"get it"}'

Use the beginning and end anchors.

Regex regex = new Regex(@"^\d$");

Use "^\d+$" if you need to match more than one digit.

Note that "\d" will match [0-9] and other digit characters like the Eastern Arabic numerals ??????????. Use "^[0-9]+$" to restrict matches to just the Arabic numerals 0 - 9.

If you need to include any numeric representations other than just digits (like decimal values for starters), then see @tchrist's comprehensive guide to parsing numbers with regular expressions.

The following CSS declaration works for me:

.td-limit {
    max-width: 70px;
    text-overflow: ellipsis;
    white-space: nowrap;
    overflow: hidden;
}

Here's another option. It works by putting an ActiveX ComboBox on top of the cell with validation enabled, and then providing autocomplete in the ComboBox instead.

Option Explicit

' Autocomplete - replacing validation lists with ActiveX ComboBox

Welcome to Java! This Nodes are like a blocks, they must be assembled to do amazing things! In this particular case, your nodes can represent a list, a linked list, You can see an example here:

public class ItemLinkedList {
    private ItemInfoNode head;
    private ItemInfoNode tail;
    private int size = 0;

    public int getSize() {
        return size;
    }

    public void addBack(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, null, tail);
            this.tail.next =node;
            this.tail = node;
        }
    }

    public void addFront(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, head, null);
            this.head.prev = node;
            this.head = node;
        }
    }

    public ItemInfo removeBack() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = tail.info;
            if (tail.prev != null) {
                tail.prev.next = null;
                tail = tail.prev;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public ItemInfo removeFront() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = head.info;
            if (head.next != null) {
                head.next.prev = null;
                head = head.next;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public class ItemInfoNode {

        private ItemInfoNode next;
        private ItemInfoNode prev;
        private ItemInfo info;

        public ItemInfoNode(ItemInfo info, ItemInfoNode next, ItemInfoNode prev) {
            this.info = info;
            this.next = next;
            this.prev = prev;
        }

        public void setInfo(ItemInfo info) {
            this.info = info;
        }

        public void setNext(ItemInfoNode node) {
            next = node;
        }

        public void setPrev(ItemInfoNode node) {
            prev = node;
        }

        public ItemInfo getInfo() {
            return info;
        }

        public ItemInfoNode getNext() {
            return next;
        }

        public ItemInfoNode getPrev() {
            return prev;
        }
    }
}

EDIT:

Declare ItemInfo as this:

public class ItemInfo {
    private String name;
    private String rfdNumber;
    private double price;
    private String originalPosition;

    public ItemInfo(){
    }

    public ItemInfo(String name, String rfdNumber, double price, String originalPosition) {
        this.name = name;
        this.rfdNumber = rfdNumber;
        this.price = price;
        this.originalPosition = originalPosition;
    }

    public String getName() {
        return name;
    }

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

    public String getRfdNumber() {
        return rfdNumber;
    }

    public void setRfdNumber(String rfdNumber) {
        this.rfdNumber = rfdNumber;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public String getOriginalPosition() {
        return originalPosition;
    }

    public void setOriginalPosition(String originalPosition) {
        this.originalPosition = originalPosition;
    }
}

Then, You can use your nodes inside the linked list like this:

public static void main(String[] args) {
    ItemLinkedList list = new ItemLinkedList();
    for (int i = 1; i <= 10; i++) {
        list.addBack(new ItemInfo("name-"+i, "rfd"+i, i, String.valueOf(i)));

    }
    while (list.size() > 0){
        System.out.println(list.removeFront().getName());
    }
}

This would be better and easy

var arr = $('input[name="user_ids[]"]').map(function(){
  return $(this).val();
}).get();

console.log(arr);

I am using Visual Studio 2017 15.4.0 version. Especially when i started use lightweight solution option, this offline thing happened to me. I tried to above solutions which are:

1. Tried to regedit option but can not see appropriate menu options. Didn't work.
2. Right click on solution, there is go online option and when i choose it that gives this error message: "The solution is offline because its associated Team Foundation Server is offline. Unable to determine the workspace for this solution."

Then from File -> Source Control -> Advanced -> Change Source Control. I saw my files. I select them and then chose bind option. That worked for me.

map can be much faster than replace

If your dictionary has more than a couple of keys, using map can be much faster than replace. There are two versions of this approach, depending on whether your dictionary exhaustively maps all possible values (and also whether you want non-matches to keep their values or be converted to NaNs):

Exhaustive Mapping

In this case, the form is very simple:

df['col1'].map(di)       # note: if the dictionary does not exhaustively map all
                         # entries then non-matched entries are changed to NaNs

Although map most commonly takes a function as its argument, it can alternatively take a dictionary or series: Documentation for Pandas.series.map

Non-Exhaustive Mapping

If you have a non-exhaustive mapping and wish to retain the existing variables for non-matches, you can add fillna:

df['col1'].map(di).fillna(df['col1'])

as in @jpp's answer here: Replace values in a pandas series via dictionary efficiently

Benchmarks

Using the following data with pandas version 0.23.1:

di = {1: "A", 2: "B", 3: "C", 4: "D", 5: "E", 6: "F", 7: "G", 8: "H" }
df = pd.DataFrame({ 'col1': np.random.choice( range(1,9), 100000 ) })

and testing with %timeit, it appears that map is approximately 10x faster than replace.

Note that your speedup with map will vary with your data. The largest speedup appears to be with large dictionaries and exhaustive replaces. See @jpp answer (linked above) for more extensive benchmarks and discussion.

Another simplest way to connect is through an OdbcConnection using App.config file like this

  <appSettings>  
    <add key="Conn" value="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|MyDB.mdb;Persist Security Info=True"/>
  </appSettings>

MyDB.mdb is my database file and it is present in current primary application folder with main exe file.

if your mdf file has password then use like this

  <appSettings>
    <add key="Conn" value="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|MyDB.mdb;Persist Security Info=True;Jet OLEDB:Database Password=Admin$@123"/>
  </appSettings>

Small tweak to Luke's answer,

 function reloadJs(src) {
    src = $('script[src$="' + src + '"]').attr("src");
    $('script[src$="' + src + '"]').remove();
    $('<script/>').attr('src', src).appendTo('head');
}

and call it like,

reloadJs("myFile.js");

This will not have any path related issues.

You need to use JSON.stringify to first serialize your object to JSON, and then specify the contentType so your server understands it's JSON. This should do the trick:

$.ajax({
    url: url,
    type: "POST",
    data: JSON.stringify(data),
    contentType: "application/json",
    complete: callback
});

Note that the JSON object is natively available in browsers that support JavaScript 1.7 / ECMAScript 5 or later. If you need legacy support you can use json2.

If you have a container and two sub containers, you can do like this

jQuery

    $("#previousbutton").click(function() {
    $("#form_sub_container1").show();
    $("#form_sub_container2").hide(); })

    $("#nextbutton").click(function() {
    $("#form_container").find(":hidden").show().next();
    $("#form_sub_container1").hide();
})

HTML

     <div id="form_container">
            <div id="form_sub_container1" style="display: block;">
            </div>

            <div id="form_sub_container2" style="display: none;">
            </div>
     </div>

There are many differences between these two. But while working practically I have found that using $state.params better. When you use more and more parameters this might be confusing to maintain in $stateParams. where if we use multiple params which are not URL param $state is very useful

 .state('shopping-request', {
      url: '/shopping-request/{cartId}',
      data: {requireLogin: true},
      params : {role: null},
      views: {
        '': {templateUrl: 'views/templates/main.tpl.html', controller: "ShoppingRequestCtrl"},
        'body@shopping-request': {templateUrl: 'views/shops/shopping-request.html'},
        'footer@shopping-request': {templateUrl: 'views/templates/footer.tpl.html'},
        'header@shopping-request': {templateUrl: 'views/templates/header.tpl.html'}
      }
    })

It's a limitation of the language. In section 6.7.8/4:

All the expressions in an initializer for an object that has static storage duration shall be constant expressions or string literals.

In section 6.6, the spec defines what must considered a constant expression. No where does it state that a const variable must be considered a constant expression. It is legal for a compiler to extend this (6.6/10 - An implementation may accept other forms of constant expressions) but that would limit portability.

If you can change my_foo so it does not have static storage, you would be okay:

int main()
{
    foo_t my_foo = foo_init;
    return 0;
}

If you have either ruby 1.9 or activesupport, you can do simply

@title = tokens[Title].try :tap, &:strip!

This is really cool, as it leverages the :try and the :tap method, which are the most powerful functional constructs in ruby, in my opinion.

An even cuter form, passing functions as symbols altogether:

@title = tokens[Title].send :try, :tap, &:strip!

Quick and Dirty Way!

It's not a good way, but for me it seems the most simplest.

Add an anchor tag which contains the modal data-target and data-toggle, have an id associated with it. (Can be added mostly anywhere in the html view)

<a href="" data-toggle="modal" data-target="#myModal" id="myModalShower"></a>

Now,

Inside the angular controller, from where you want to trigger the modal just use

angular.element('#myModalShower').trigger('click');

This will mimic a click to the button based on the angular code and the modal will appear.

In my case, I had to call an API repeatedly in a loop, which resulted in halt of my system returning a 403 Forbidden Error. Since my API provider does not allow multiple requests from the same client within milliseconds, I had to use a delay of 1 second at least :

foreach (var it in list)
{
    Thread.Sleep(1000);
    // Call API
}

One way is to add your shortcut keys to the commands themselves them as InputGestures. Commands are implemented as RoutedCommands.

This enables the shortcut keys to work even if they're not hooked up to any controls. And since menu items understand keyboard gestures, they'll automatically display your shortcut key in the menu items text, if you hook that command up to your menu item.

1. Create static attribute to hold a command (preferably as a property in a static class you create for commands - but for a simple example, just using a static attribute in window.cs):

    public static RoutedCommand MyCommand = new RoutedCommand();
   

2. Add the shortcut key(s) that should invoke method:

    MyCommand.InputGestures.Add(new KeyGesture(Key.S, ModifierKeys.Control));
   

3. Create a command binding that points to your method to call on execute. Put these in the command bindings for the UI element under which it should work for (e.g., the window) and the method:

    <Window.CommandBindings>
        <CommandBinding Command="{x:Static local:MyWindow.MyCommand}" Executed="MyCommandExecuted"/>
    </Window.CommandBindings>
   
    private void MyCommandExecuted(object sender, ExecutedRoutedEventArgs e) { ... }
   

In my case, I was getting this error on the same machine, in my test client-server application. But this problem was resolved by "Update Service Reference".

By default wordpress uses MD5. You can upgrade it to blowfish or extended DES.

And it's unlikely too -- EOT is a fairly restrictive format that is supported only by IE. Both Safari 3.1 and Firefox 3.1 (well the current alpha) and possibly Opera 9.6 support true type font (ttf) embedding, and at least Safari supports SVG fonts through the same mechanism. A list apart had a good discussion about this a while back.

For many use cases, the answer you want is:

ys = set(y)
[item for item in x if item not in ys]

This is a hybrid between aaronasterling's answer and quantumSoup's answer.

aaronasterling's version does len(y) item comparisons for each element in x, so it takes quadratic time. quantumSoup's version uses sets, so it does a single constant-time set lookup for each element in x—but, because it converts both x and y into sets, it loses the order of your elements.

By converting only y into a set, and iterating x in order, you get the best of both worlds—linear time, and order preservation.*

However, this still has a problem from quantumSoup's version: It requires your elements to be hashable. That's pretty much built into the nature of sets.** If you're trying to, e.g., subtract a list of dicts from another list of dicts, but the list to subtract is large, what do you do?

If you can decorate your values in some way that they're hashable, that solves the problem. For example, with a flat dictionary whose values are themselves hashable:

ys = {tuple(item.items()) for item in y}
[item for item in x if tuple(item.items()) not in ys]

If your types are a bit more complicated (e.g., often you're dealing with JSON-compatible values, which are hashable, or lists or dicts whose values are recursively the same type), you can still use this solution. But some types just can't be converted into anything hashable.

If your items aren't, and can't be made, hashable, but they are comparable, you can at least get log-linear time (O(N*log M), which is a lot better than the O(N*M) time of the list solution, but not as good as the O(N+M) time of the set solution) by sorting and using bisect:

ys = sorted(y)
def bisect_contains(seq, item):
    index = bisect.bisect(seq, item)
    return index < len(seq) and seq[index] == item
[item for item in x if bisect_contains(ys, item)]

If your items are neither hashable nor comparable, then you're stuck with the quadratic solution.

_{* Note that you could also do this by using a pair of OrderedSet objects, for which you can find recipes and third-party modules. But I think this is simpler.}

_{** The reason set lookups are constant time is that all it has to do is hash the value and see if there's an entry for that hash. If it can't hash the value, this won't work.}

The problem is due to having jQuery instances more than one time. Take care if you are using many files with multiples instance of jQuery. Just leave 1 instance of jQuery and your code will work.

<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.4.min.js"></script>

A few resources:

• TimeDatePicker (jQuery Plugin)
• jQuery.timepickr
• jQuery.ptTimeSelect
• Time Picker
• Fancy Time Picker
• NoGray Time Picker

First ssh-add then ssh user@ip

Using this code you can write to a text file in the SDCard. Along with it, you need to set a permission in the Android Manifest.

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

This is the code :

public void generateNoteOnSD(Context context, String sFileName, String sBody) {
    try {
        File root = new File(Environment.getExternalStorageDirectory(), "Notes");
        if (!root.exists()) {
            root.mkdirs();
        }
        File gpxfile = new File(root, sFileName);
        FileWriter writer = new FileWriter(gpxfile);
        writer.append(sBody);
        writer.flush();
        writer.close();
        Toast.makeText(context, "Saved", Toast.LENGTH_SHORT).show();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

Before writing files you must also check whether your SDCard is mounted & the external storage state is writable.

Environment.getExternalStorageState()

Many answers for this questions are great and some have even looked into the corner cases. I would like to add a simple answer that can be of daily use... where you mostly get into those corner cases (like having escaped commas or commas in quotes etc.,).

FS (Field Separator) is the variable whose value is dafaulted to space. So awk by default splits at space for any line.

So using BEGIN (Execute before taking input) we can set this field to anything we want...

awk 'BEGIN {FS = ","}; {print $3}'

The above code will print the 3rd column in a csv file.

You can't have a <button> inside an <a> element. As W3's content model description for the <a> element states:

"there must be no interactive content descendant."

(a <button> is considered interactive content)

To get the effect you're looking for, you can ditch the <a> tags and add a simple event handler to each button which navigates the browser to the desired location, e.g.

<input type="button" value="stackoverflow.com" onClick="javascript:location.href = 'http://stackoverflow.com';" />

Please consider not doing this, however; there's a reason regular links work as they do:

• Users can instantly recognize links and understand that they navigate to other pages
• Search engines can identify them as links and follow them
• Screen readers can identify them as links and advise their users appropriately

You also add a completely unnecessary requirement to have JavaScript enabled just to perform a basic navigation; this is such a fundamental aspect of the web that I would consider such a dependency as unacceptable.

You can style your links, if desired, using a background image or background color, border and other techniques, so that they look like buttons, but under the covers, they should be ordinary links.

It's been a long time since I've worked in a Windows environment, but I would suggest that you look at using WMI.

This is a common question in C++ programming. There are two valid answers to this. There are advantages and disadvantages to both answers and your choice will depend on context. The common answer is to put all the implementation in the header file, but there's another approach will will be suitable in some cases. The choice is yours.

The code in a template is merely a 'pattern' known to the compiler. The compiler won't compile the constructors cola<float>::cola(...) and cola<string>::cola(...) until it is forced to do so. And we must ensure that this compilation happens for the constructors at least once in the entire compilation process, or we will get the 'undefined reference' error. (This applies to the other methods of cola<T> also.)

Understanding the problem

The problem is caused by the fact that main.cpp and cola.cpp will be compiled separately first. In main.cpp, the compiler will implicitly instantiate the template classes cola<float> and cola<string> because those particular instantiations are used in main.cpp. The bad news is that the implementations of those member functions are not in main.cpp, nor in any header file included in main.cpp, and therefore the compiler can't include complete versions of those functions in main.o. When compiling cola.cpp, the compiler won't compile those instantiations either, because there are no implicit or explicit instantiations of cola<float> or cola<string>. Remember, when compiling cola.cpp, the compiler has no clue which instantiations will be needed; and we can't expect it to compile for every type in order to ensure this problem never happens! (cola<int>, cola<char>, cola<ostream>, cola< cola<int> > ... and so on ...)

The two answers are:

• Tell the compiler, at the end of cola.cpp, which particular template classes will be required, forcing it to compile cola<float> and cola<string>.
• Put the implementation of the member functions in a header file that will be included every time any other 'translation unit' (such as main.cpp) uses the template class.

Answer 1: Explicitly instantiate the template, and its member definitions

At the end of cola.cpp, you should add lines explicitly instantiating all the relevant templates, such as

template class cola<float>;
template class cola<string>;

and you add the following two lines at the end of nodo_colaypila.cpp:

template class nodo_colaypila<float>;
template class nodo_colaypila<std :: string>;

This will ensure that, when the compiler is compiling cola.cpp that it will explicitly compile all the code for the cola<float> and cola<string> classes. Similarly, nodo_colaypila.cpp contains the implementations of the nodo_colaypila<...> classes.

In this approach, you should ensure that all the of the implementation is placed into one .cpp file (i.e. one translation unit) and that the explicit instantation is placed after the definition of all the functions (i.e. at the end of the file).

Answer 2: Copy the code into the relevant header file

The common answer is to move all the code from the implementation files cola.cpp and nodo_colaypila.cpp into cola.h and nodo_colaypila.h. In the long run, this is more flexible as it means you can use extra instantiations (e.g. cola<char>) without any more work. But it could mean the same functions are compiled many times, once in each translation unit. This is not a big problem, as the linker will correctly ignore the duplicate implementations. But it might slow down the compilation a little.

Summary

The default answer, used by the STL for example and in most of the code that any of us will write, is to put all the implementations in the header files. But in a more private project, you will have more knowledge and control of which particular template classes will be instantiated. In fact, this 'bug' might be seen as a feature, as it stops users of your code from accidentally using instantiations you have not tested for or planned for ("I know this works for cola<float> and cola<string>, if you want to use something else, tell me first and will can verify it works before enabling it.").

Finally, there are three other minor typos in the code in your question:

• You are missing an #endif at the end of nodo_colaypila.h
• in cola.h nodo_colaypila<T>* ult, pri; should be nodo_colaypila<T> *ult, *pri; - both are pointers.
• nodo_colaypila.cpp: The default parameter should be in the header file nodo_colaypila.h, not in this implementation file.

You need to subclass UITableViewCell and subclass method willTransitionToState:(UITableViewCellStateMask)state which is called whenever user swipes the cell. The state flags will let you know if the Delete button is showing, and show/hide your More button there.

Unfortunately this method gives you neither the width of the Delete button nor the animation time. So you need to observer & hard-code your More button's frame and animation time into your code (I personally think Apple needs to do something about this).

Try negation operator ! before $(this):

if (!$(this).parent().next().is('ul')){

Unique is a keyword used in the Create Table() directive to denote that a field will contain unique data, usually used for natural keys, foreign keys etc.

For example:

Create Table Employee(   
    Emp_PKey Int Identity(1, 1) Constraint PK_Employee_Emp_PKey Primary Key,  
    Emp_SSN Numeric Not Null Unique,  
    Emp_FName varchar(16),   
    Emp_LName varchar(16) 
)

i.e. Someone's Social Security Number would likely be a unique field in your table, but not necessarily the primary key.

Distinct is used in the Select statement to notify the query that you only want the unique items returned when a field holds data that may not be unique.

Select Distinct Emp_LName
From Employee

You may have many employees with the same last name, but you only want each different last name.

Obviously if the field you are querying holds unique data, then the Distinct keyword becomes superfluous.

Neither of the first two answers worked for me with multiple elements that can open dialogs that point to different pages.

This feels like the cleanest solution, only creates the dialog object once on load and then uses the events to open/close/display appropriately:

$(function () {
      var ajaxDialog = $('<div id="ajax-dialog" style="display:hidden"></div>').appendTo('body');
      ajaxDialog.dialog({autoOpen: false});
      $('a.ajax-dialog-opener').live('click', function() {
          // load remote content
          ajaxDialog.load(this.href);
          ajaxDialog.dialog("open");
          //prevent the browser from following the link
          return false;
      });
}); 

I found a solution that doesn't need to access directly the pixel data and loop through it to perform the downsampling. Depending on the size of the image this can be very resource intensive, and it would be better to use the browser's internal algorithms.

The drawImage() function is using a linear-interpolation, nearest-neighbor resampling method. That works well when you are not resizing down more than half the original size.

If you loop to only resize max one half at a time, the results would be quite good, and much faster than accessing pixel data.

This function downsample to half at a time until reaching the desired size:

  function resize_image( src, dst, type, quality ) {
     var tmp = new Image(),
         canvas, context, cW, cH;

     type = type || 'image/jpeg';
     quality = quality || 0.92;

     cW = src.naturalWidth;
     cH = src.naturalHeight;

     tmp.src = src.src;
     tmp.onload = function() {

        canvas = document.createElement( 'canvas' );

        cW /= 2;
        cH /= 2;

        if ( cW < src.width ) cW = src.width;
        if ( cH < src.height ) cH = src.height;

        canvas.width = cW;
        canvas.height = cH;
        context = canvas.getContext( '2d' );
        context.drawImage( tmp, 0, 0, cW, cH );

        dst.src = canvas.toDataURL( type, quality );

        if ( cW <= src.width || cH <= src.height )
           return;

        tmp.src = dst.src;
     }

  }
  // The images sent as parameters can be in the DOM or be image objects
  resize_image( $( '#original' )[0], $( '#smaller' )[0] );

If you are passing data to a DOM element from the server, you should set the data on the element:

<a id="foo" data-foo="bar" href="#">foo!</a>

The data can then be accessed using .data() in jQuery:

console.log( $('#foo').data('foo') );
//outputs "bar"

However when you store data on a DOM node in jQuery using data, the variables are stored on the node object. This is to accommodate complex objects and references as storing the data on the node element as an attribute will only accommodate string values.

$('#foo').data('foo', 'baz');

console.log( $('#foo').attr('data-foo') );
//outputs "bar" as the attribute was never changed

console.log( $('#foo').data('foo') );
//outputs "baz" as the value has been updated on the object

Also, the naming convention for data attributes has a bit of a hidden "gotcha":

<a id="bar" data-foo-bar-baz="fizz-buzz" href="#">fizz buzz!</a>

console.log( $('#bar').data('fooBarBaz') );
//outputs "fizz-buzz" as hyphens are automatically camelCase'd

The hyphenated key will still work:

<a id="bar" data-foo-bar-baz="fizz-buzz" href="#">fizz buzz!</a>

console.log( $('#bar').data('foo-bar-baz') );
//still outputs "fizz-buzz"

However the object returned by .data() will not have the hyphenated key set:

$('#bar').data().fooBarBaz; //works
$('#bar').data()['fooBarBaz']; //works
$('#bar').data()['foo-bar-baz']; //does not work

It's for this reason I suggest avoiding the hyphenated key in javascript.

For HTML, keep using the hyphenated form. HTML attributes are supposed to get ASCII-lowercased automatically, so <div data-foobar></div>, <DIV DATA-FOOBAR></DIV>, and <dIv DaTa-FoObAr></DiV> are supposed to be treated as identical, but for the best compatibility the lower case form should be preferred.

The .data() method will also perform some basic auto-casting if the value matches a recognized pattern:

<a id="foo"
    href="#"
    data-str="bar"
    data-bool="true"
    data-num="15"
    data-json='{"fizz":["buzz"]}'>foo!</a>

$('#foo').data('str');  //`"bar"`
$('#foo').data('bool'); //`true`
$('#foo').data('num');  //`15`
$('#foo').data('json'); //`{fizz:['buzz']}`

This auto-casting ability is very convenient for instantiating widgets & plugins:

$('.widget').each(function () {
    $(this).widget($(this).data());
    //-or-
    $(this).widget($(this).data('widget'));
});

If you absolutely must have the original value as a string, then you'll need to use .attr():

<a id="foo" href="#" data-color="ABC123"></a>
<a id="bar" href="#" data-color="654321"></a>

$('#foo').data('color').length; //6
$('#bar').data('color').length; //undefined, length isn't a property of numbers

$('#foo').attr('data-color').length; //6
$('#bar').attr('data-color').length; //6

_{This was a contrived example. For storing color values, I used to use numeric hex notation (i.e. 0xABC123), but it's worth noting that hex was parsed incorrectly in jQuery versions before 1.7.2, and is no longer parsed into a Number as of jQuery 1.8 rc 1.}

jQuery 1.8 rc 1 changed the behavior of auto-casting. Before, any format that was a valid representation of a Number would be cast to Number. Now, values that are numeric are only auto-cast if their representation stays the same. This is best illustrated with an example.

<a id="foo"
    href="#"
    data-int="1000"
    data-decimal="1000.00"
    data-scientific="1e3"
    data-hex="0x03e8">foo!</a>

                              // pre 1.8    post 1.8
$('#foo').data('int');        //    1000        1000
$('#foo').data('decimal');    //    1000   "1000.00"
$('#foo').data('scientific'); //    1000       "1e3"
$('#foo').data('hex');        //    1000     "0x03e8"

If you plan on using alternative numeric syntaxes to access numeric values, be sure to cast the value to a Number first, such as with a unary + operator.

+$('#foo').data('hex'); // 1000

When the normType is NORM_MINMAX, cv::normalize normalizes _src in such a way that the min value of dst is alpha and max value of dst is beta. cv::normalize does its magic using only scales and shifts (i.e. adding constants and multiplying by constants).

CV_8UC1 says how many channels dst has.

The documentation here is pretty clear: http://docs.opencv.org/modules/core/doc/operations_on_arrays.html#normalize

In the vast majority of cases, the "stringification" of a SQLAlchemy statement or query is as simple as:

print(str(statement))

This applies both to an ORM Query as well as any select() or other statement.

Note: the following detailed answer is being maintained on the sqlalchemy documentation.

To get the statement as compiled to a specific dialect or engine, if the statement itself is not already bound to one you can pass this in to compile():

print(statement.compile(someengine))

or without an engine:

from sqlalchemy.dialects import postgresql
print(statement.compile(dialect=postgresql.dialect()))

When given an ORM Query object, in order to get at the compile() method we only need access the .statement accessor first:

with regards to the original stipulation that bound parameters are to be "inlined" into the final string, the challenge here is that SQLAlchemy normally is not tasked with this, as this is handled appropriately by the Python DBAPI, not to mention bypassing bound parameters is probably the most widely exploited security holes in modern web applications. SQLAlchemy has limited ability to do this stringification in certain circumstances such as that of emitting DDL. In order to access this functionality one can use the 'literal_binds' flag, passed to compile_kwargs:

from sqlalchemy.sql import table, column, select

t = table('t', column('x'))

s = select([t]).where(t.c.x == 5)

print(s.compile(compile_kwargs={"literal_binds": True}))

the above approach has the caveats that it is only supported for basic types, such as ints and strings, and furthermore if a bindparam without a pre-set value is used directly, it won't be able to stringify that either.

To support inline literal rendering for types not supported, implement a TypeDecorator for the target type which includes a TypeDecorator.process_literal_param method:

from sqlalchemy import TypeDecorator, Integer


class MyFancyType(TypeDecorator):
    impl = Integer

    def process_literal_param(self, value, dialect):
        return "my_fancy_formatting(%s)" % value

from sqlalchemy import Table, Column, MetaData

tab = Table('mytable', MetaData(), Column('x', MyFancyType()))

print(
    tab.select().where(tab.c.x > 5).compile(
        compile_kwargs={"literal_binds": True})
)

producing output like:

SELECT mytable.x
FROM mytable
WHERE mytable.x > my_fancy_formatting(5)

You can use COALESCE:

SELECT  orderhed.ordernum, 
    orderhed.orderdate, 
    currrate.currencycode,  
    coalesce(currrate.currentrate, 1) as currentrate
FROM orderhed 
LEFT OUTER JOIN currrate 
    ON orderhed.company = currrate.company 
    AND orderhed.orderdate = currrate.effectivedate

Or even IsNull():

SELECT  orderhed.ordernum, 
    orderhed.orderdate, 
    currrate.currencycode,  
    IsNull(currrate.currentrate, 1) as currentrate
FROM orderhed 
LEFT OUTER JOIN currrate 
    ON orderhed.company = currrate.company 
    AND orderhed.orderdate = currrate.effectivedate

Here is an article to help decide between COALESCE and IsNull:

The correct answer is "python collections do not have a foreach". In native python we need to resort to the external for _element_ in _collection_ syntax which is not what the OP is after.

Python is in general quite weak for functionals programming. There are a few libraries to mitigate a bit. I helped author one of these infixpy https://pypi.org/project/infixpy/

from infixpy import Seq
(Seq([1,2,3]).foreach(lambda x: print(x)))

I had the same exact problem and found the solution through the use of larachat.

Here's how to fix it you need to have your homestead.yaml file settings correct. If you want to know how its done follow Jeffery Way tutorial on homestead 2.0 https://laracasts.com/lessons/say-hello-to-laravel-homestead-two.

Now to fix Input not specified issue you need to ssh into homestead box and type

serve domain.app /home/vagrant/Code/path/to/public/directory this will generate a serve script for nginx. You will need to do this everytime you switch projects.

• You can make the legend text smaller by specifying set_size of FontProperties.
• Resources:
  • Legend guide
  • matplotlib.legend
  • matplotlib.pyplot.legend
  • matplotlib.font_manager
    • set_size(self, size)
    • Valid font size are xx-small, x-small, small, medium, large, x-large, xx-large, larger, smaller, None
  • Real Python: Python Plotting With Matplotlib (Guide)

import matplotlib.pyplot as plt
from matplotlib.font_manager import FontProperties

fontP = FontProperties()
fontP.set_size('xx-small')

p1, = plt.plot([1, 2, 3], label='Line 1')
p2, = plt.plot([3, 2, 1], label='Line 2')
plt.legend(handles=[p1, p2], title='title', bbox_to_anchor=(1.05, 1), loc='upper left', prop=fontP)

• As noted by Mateen Ulhaq, fontsize='xx-small' also works, without importing FontProperties.

plt.legend(handles=[p1, p2], title='title', bbox_to_anchor=(1.05, 1), loc='upper left', fontsize='xx-small')

Any color parse into int simplest two way here:

1) Get System Color

int redColorValue = Color.RED;

2) Any Color Hex Code as a String Argument

int greenColorValue = Color.parseColor("#00ff00")

MUST REMEMBER in above code Color class must be android.graphics...!

While @yydl gives a compelling reason on why the newInstance method is better:

If Android decides to recreate your Fragment later, it's going to call the no-argument constructor of your fragment. So overloading the constructor is not a solution.

it's still quite possible to use a constructor. To see why this is, first we need to see why the above workaround is used by Android.

Before a fragment can be used, an instance is needed. Android calls YourFragment() (the no arguments constructor) to construct an instance of the fragment. Here any overloaded constructor that you write will be ignored, as Android can't know which one to use.

In the lifetime of an Activity the fragment gets created as above and destroyed multiple times by Android. This means that if you put data in the fragment object itself, it will be lost once the fragment is destroyed.

To workaround, android asks that you store data using a Bundle (calling setArguments()), which can then be accessed from YourFragment. Argument bundles are protected by Android, and hence are guaranteed to be persistent.

One way to set this bundle is by using a static newInstance method:

public static YourFragment newInstance (int data) {
    YourFragment yf = new YourFragment()
    /* See this code gets executed immediately on your object construction */
    Bundle args = new Bundle();
    args.putInt("data", data);
    yf.setArguments(args);
    return yf;
}

However, a constructor:

public YourFragment(int data) {
    Bundle args = new Bundle();
    args.putInt("data", data);
    setArguments(args);
}

can do exactly the same thing as the newInstance method.

Naturally, this would fail, and is one of the reasons Android wants you to use the newInstance method:

public YourFragment(int data) {
    this.data = data; // Don't do this
}

As further explaination, here's Android's Fragment Class:

/**
 * Supply the construction arguments for this fragment.  This can only
 * be called before the fragment has been attached to its activity; that
 * is, you should call it immediately after constructing the fragment.  The
 * arguments supplied here will be retained across fragment destroy and
 * creation.
 */
public void setArguments(Bundle args) {
    if (mIndex >= 0) {
        throw new IllegalStateException("Fragment already active");
    }
    mArguments = args;
}

Note that Android asks that the arguments be set only at construction, and guarantees that these will be retained.

EDIT: As pointed out in the comments by @JHH, if you are providing a custom constructor that requires some arguments, then Java won't provide your fragment with a no arg default constructor. So this would require you to define a no arg constructor, which is code that you could avoid with the newInstance factory method.

EDIT: Android doesn't allow using an overloaded constructor for fragments anymore. You must use the newInstance method.

This is the logger class that I use. The private Log() method has EventLog.WriteEntry() in it, which is how you actually write to the event log. I'm including all of this code here because it's handy. In addition to logging, this class will also make sure the message isn't too long to write to the event log (it will truncate the message). If the message was too long, you'd get an exception. The caller can also specify the source. If the caller doesn't, this class will get the source. Hope it helps.

By the way, you can get an ObjectDumper from the web. I didn't want to post all that here. I got mine from here: C:\Program Files (x86)\Microsoft Visual Studio 10.0\Samples\1033\CSharpSamples.zip\LinqSamples\ObjectDumper

Bootstrap is just a big, useful, yet simple CSS file - not a framework or anything you can't override. I say this because I've noticed many developers got stick with BS classes and became lazy "I-can't-write-CSS-code-anymore" coders [this not being your case of course!].

If it features something you need, go with Bootstrap classes - if not, go write your additional code in good ol' style.css.

To have best of both worlds, you may write your own declarations in LESS and recompile the whole thing upon your needs, minimizing server request as a bonus.

It turns out that the solution is to stop all the related services and solve the “Another daemon is already running” issue.

The commands i used to solve the issue are as follows:

sudo /opt/lampp/lampp stop              
sudo /etc/init.d/apache2 stop    
sudo /etc/init.d/mysql stop

Or, you can also type instead:

sudo service apache2 stop
sudo service mysql stop

After that, we again start the lampp services:

sudo /opt/lampp/lampp start

Now, there must be no problems while opening:

http://localhost                  
http://localhost/phpmyadmin

The @Devart's version is correct, but here are some improvements to avoid having error. I've edited the @Devart's answer, but it was not accepted.

SET FOREIGN_KEY_CHECKS = 0;
SET GROUP_CONCAT_MAX_LEN=32768;
SET @tables = NULL;
SELECT GROUP_CONCAT('`', table_name, '`') INTO @tables
  FROM information_schema.tables
  WHERE table_schema = (SELECT DATABASE());
SELECT IFNULL(@tables,'dummy') INTO @tables;

SET @tables = CONCAT('DROP TABLE IF EXISTS ', @tables);
PREPARE stmt FROM @tables;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SET FOREIGN_KEY_CHECKS = 1;

This script will not raise error with NULL result in case when you already deleted all tables in the database by adding at least one nonexistent - "dummy" table.

And it fixed in case when you have many tables.

And This small change to drop all view exist in the Database

SET FOREIGN_KEY_CHECKS = 0;
SET GROUP_CONCAT_MAX_LEN=32768;
SET @views = NULL;
SELECT GROUP_CONCAT('`', TABLE_NAME, '`') INTO @views
  FROM information_schema.views
  WHERE table_schema = (SELECT DATABASE());
SELECT IFNULL(@views,'dummy') INTO @views;

SET @views = CONCAT('DROP VIEW IF EXISTS ', @views);
PREPARE stmt FROM @views;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SET FOREIGN_KEY_CHECKS = 1;

It assumes that you run the script from Database you want to delete. Or run this before:

USE REPLACE_WITH_DATABASE_NAME_YOU_WANT_TO_DELETE;

This shows the differences from the empty tree to your current working tree. Which happens to count all lines in your current working tree.

To get the numbers in your current working tree, do this:

git diff --shortstat `git hash-object -t tree /dev/null`

It will give you a string like 1770 files changed, 166776 insertions(+).

I know this is an old question, but I wanted to add something to the answers already here in hopes of helping someone else.

You can script the ftp command with the -s:filename option. The syntax is just a list of commands to pass to the ftp shell, each terminated by a newline. This page has a nice reference to the commands that can be performed with ftp.

Upload/Download Entire Directory Structure

Using the normal ftp doesn't work very well when you need to have an entire directory tree copied to or from a ftp site. So you could use something like these to handle those situations.

These scripts works with the Windows ftp command and allows for uploading and downloading of entire directories from a single command. This makes it pretty self reliant when using on different systems.

Basically what they do is map out the directory structure to be up/downloaded, dump corresponding ftp commands to a file, then execute those commands when the mapping has finished.

Adding to the other answers:

you can create a function for trimming the date from a datetime

CREATE FUNCTION dbo.f_trimdate (@dat datetime) RETURNS DATETIME AS BEGIN
    RETURN CONVERT(DATETIME, CONVERT(FLOAT, @dat) - CONVERT(INT, @dat))
END

So this:

DECLARE @dat DATETIME
SELECT @dat = '20080201 02:25:46.000'
SELECT dbo.f_trimdate(@dat)

Will return 1900-01-01 02:25:46.000

You can do that using Requestify, a very simple and cool HTTP client I wrote for nodeJS, it support easy use of cookies and it also supports caching.

To perform a request with a cookie attached just do the following:

var requestify = require('requestify');
requestify.post('http://google.com', {}, {
    cookies: {
        sessionCookie: 'session-cookie-data'   
    }
});

The problem with SQL injection is, that a user input is used as part of the SQL statement. By using prepared statements you can force the user input to be handled as the content of a parameter (and not as a part of the SQL command).

But if you don't use the user input as a parameter for your prepared statement but instead build your SQL command by joining strings together, you are still vulnerable to SQL injections even when using prepared statements.

If you are using -o (or -a), it needs to be inside the brackets of the test command:

if [ "$age" -le "7" -o "$age" -ge " 65" ]

However, their use is deprecated, and you should use separate test commands joined by || (or &&) instead:

if [ "$age" -le "7" ] || [ "$age" -ge " 65" ]

Make sure the closing brackets are preceded with whitespace, as they are technically arguments to [, not simply syntax.

In bash and some other shells, you can use the superior [[ expression as shown in kamituel's answer. The above will work in any POSIX-compliant shell.

You can also use Arrays.copyOfRange.

Example:

public static void main(String[] args) {
    int[] a = {1,2,3};
    int[] b = Arrays.copyOfRange(a, 0, a.length);
    a[0] = 5;
    System.out.println(Arrays.toString(a)); // [5,2,3]
    System.out.println(Arrays.toString(b)); // [1,2,3]
}

This method is similar to Arrays.copyOf, but it's more flexible. Both of them use System.arraycopy under the hood.

HTML:

<label class="block"><input type="radio" name="calculation" value="add">+</label>
<label class="block"><input type="radio" name="calculation" value="sub">-</label>
<label class="block"><input type="radio" name="calculation" value="mul">*</label>
<label class="block"><input type="radio" name="calculation" value="div">/</label>

<p id="result"></p>

JAVAScript:

var options = document.getElementsByName("calculation");

for (var i = 0; i < options.length; i++) {
    if (options[i].checked) {
        // do whatever you want with the checked radio
        var calc = options[i].value;
        }
    }
    if(typeof calc == "undefined"){
        document.getElementById("result").innerHTML = " select the operation you want to perform";
        return false;
}

A lot of problems can be avoided by only creating a branch to work on & not working on master:

git checkout -b mybranch

The following works for remote commits already pushed & a mixture of remote pushed commits / local only commits:

# example merging 4 commits

git checkout mybranch
git rebase -i mybranch~4 mybranch

# at the interactive screen
# choose fixup for commit: 2 / 3 / 4

git push -u origin +mybranch

I also have some pull request notes which may be helpful.

Your code doesn't work (parse) because you have an extra ) at the end that causes a Parse Error. Count, you have 2 ( and 3 ). It would work fine if you fix that, but strtotime() returns a timestamp, so to get a human readable time use date().

$selectedTime = "9:15:00";
$endTime = strtotime("+15 minutes", strtotime($selectedTime));
echo date('h:i:s', $endTime);

Get an editor that will syntax highlight and show unmatched parentheses, braces, etc.

To just do straight time without any TZ or DST and add 15 minutes (read zerkms comment):

 $endTime = strtotime($selectedTime) + 900;  //900 = 15 min X 60 sec

Still, the ) is the main issue here.

class LinksParser(HTMLParser.HTMLParser):
  def __init__(self):
    HTMLParser.HTMLParser.__init__(self)
    self.recording = 0
    self.data = []

  def handle_starttag(self, tag, attributes):
    if tag != 'div':
      return
    if self.recording:
      self.recording += 1
      return
    for name, value in attributes:
      if name == 'id' and value == 'remository':
        break
    else:
      return
    self.recording = 1

  def handle_endtag(self, tag):
    if tag == 'div' and self.recording:
      self.recording -= 1

  def handle_data(self, data):
    if self.recording:
      self.data.append(data)

self.recording counts the number of nested div tags starting from a "triggering" one. When we're in the sub-tree rooted in a triggering tag, we accumulate the data in self.data.

The data at the end of the parse are left in self.data (a list of strings, possibly empty if no triggering tag was met). Your code from outside the class can access the list directly from the instance at the end of the parse, or you can add appropriate accessor methods for the purpose, depending on what exactly is your goal.

The class could be easily made a bit more general by using, in lieu of the constant literal strings seen in the code above, 'div', 'id', and 'remository', instance attributes self.tag, self.attname and self.attvalue, set by __init__ from arguments passed to it -- I avoided that cheap generalization step in the code above to avoid obscuring the core points (keep track of a count of nested tags and accumulate data into a list when the recording state is active).

Essentially console.log() allows you to output variables in your javascript debugger of choice instead of flashing an alert() every time you want to inspect something... additionally, for more complex objects it will give you a tree view to inspect the object further instead of having to convert elements to strings like an alert().

If you want an exact result, use sympy.binomial. It seems to be the fastest method, hands down.

x = 1000000
y = 234050

%timeit scipy.misc.comb(x, y, exact=True)
1 loops, best of 3: 1min 27s per loop

%timeit gmpy.comb(x, y)
1 loops, best of 3: 1.97 s per loop

%timeit int(sympy.binomial(x, y))
100000 loops, best of 3: 5.06 µs per loop

It literally means "Not a Number." I suspect something is wrong with your conversion process.

Check out the Not A Number section at this reference

import java.io.PrintWriter;
import java.io.File;

public class Testing {

  public static void main(String[] args) throws IOException {

    File file = new File ("C:/Users/Me/Desktop/directory/file.txt");
    PrintWriter printWriter = new PrintWriter ("file.txt");
    printWriter.println ("hello");
    printWriter.close ();       
  }
}

throw an exception for the file.

You can use $query->getSingleResult(), which will throw an exception if more than one result are found, or if no result is found. (see the related phpdoc here https://github.com/doctrine/doctrine2/blob/master/lib/Doctrine/ORM/AbstractQuery.php#L791)

There's also the less famous $query->getOneOrNullResult() which will throw an exception if more than one result are found, and return null if no result is found. (see the related phpdoc here https://github.com/doctrine/doctrine2/blob/master/lib/Doctrine/ORM/AbstractQuery.php#L752)

In SQL Management Studio you can:

1. Right click on the result set grid, select 'Save Result As...' and save in.

2. On a tool bar toggle 'Result to Text' button. This will prompt for file name on each query run.

If you need to automate it, use bcp tool.

Overall

SELECT
       COUNT(DISTINCT `site_id`) as distinct_sites
  FROM `cp_visits`
 WHERE ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)

Or per site

  SELECT
         `site_id` as site,
         COUNT(DISTINCT `user_id`) as distinct_users_per_site
    FROM `cp_visits`
   WHERE ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)
GROUP BY `site_id`

Having the time column in the result doesn't make sense - since you are aggregating the rows, showing one particular time is irrelevant, unless it is the min or max you are after.

This exception is thrown when you try to index to something that isn't there, for example:

Dictionary<String, String> test = new Dictionary<String,String>();
test.Add("Key1","Value1");
string error = test["Key2"];

Often times, something like an object will be the key, which undoubtedly makes it harder to get. However, you can always write the following (or even wrap it up in an extension method):

if (test.ContainsKey(myKey))
   return test[myKey];
else
   throw new Exception(String.Format("Key {0} was not found", myKey));

Or more efficient (thanks to @ScottChamberlain)

T retValue;
if (test.TryGetValue(myKey, out retValue))
    return retValue;
else
   throw new Exception(String.Format("Key {0} was not found", myKey));

Microsoft chose not to do this, probably because it would be useless when used on most objects. Its simple enough to do yourself, so just roll your own!

This should work:

$('.myClass, .myOtherClass').removeClass('theclass');

You must add the multiple selectors all in the first argument to $(), otherwise you are giving jQuery a context in which to search, which is not what you want.

It's the same as you would do in CSS.

Based on docker documentation: https://docs.docker.com/compose/compose-file/#/command

I simply put hostname: <string> in my docker-compose file.

E.g.:

[...]

lb01:
  hostname: at-lb01
  image: at-client-base:v1

[...]

and container lb01 picks up at-lb01 as hostname.

This is very late but i like to share my experience this same issue. i face the same issue in Android studio i tried to some other solution that i found in internet but nothing works for me unless i REBUILD THE PROJECT and it solve my issue.

Hope this will works for you too.

Happy coding.

Starting in SQL Server 2017 the STRING_AGG function is available which simplifies the logic considerably:

select FieldA, string_agg(FieldB, '') as data
from yourtable
group by FieldA

See SQL Fiddle with Demo

In SQL Server you can use FOR XML PATH to get the result:

select distinct t1.FieldA,
  STUFF((SELECT distinct '' + t2.FieldB
         from yourtable t2
         where t1.FieldA = t2.FieldA
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,0,'') data
from yourtable t1;

See SQL Fiddle with Demo

This is because you define your "doc" variable outside of your click event. The first time you click the button the doc variable contains a new jsPDF object. But when you click for a second time, this variable can't be used in the same way anymore. As it is already defined and used the previous time.

change it to:

$(function () {

    var specialElementHandlers = {
        '#editor': function (element,renderer) {
            return true;
        }
    };
 $('#cmd').click(function () {
        var doc = new jsPDF();
        doc.fromHTML(
            $('#target').html(), 15, 15, 
            { 'width': 170, 'elementHandlers': specialElementHandlers }, 
            function(){ doc.save('sample-file.pdf'); }
        );

    });  
});

and it will work.

If you're having this issue, and try to run bundle exec jekyll serve per this Jekyll documentation, it'll ask you to run bundle install, which should prompt you to install any missing gems, which in this case will be rake. This should resolve your issue.

You may also need to run bundle update to ensure Gemfile.lock is referencing the most up-to-date gems.

For the answer above, the default serial port is

        serialParams.BaudRate = 9600;
        serialParams.ByteSize = 8;
        serialParams.StopBits = TWOSTOPBITS;
        serialParams.Parity = NOPARITY;

In this case why Java allows downcasting if it cannot be executed at the runtime?

I believe this is because there is no way for the compiler to know at compile-time if the cast will succeed or not. For your example, it's simple to see that the cast will fail, but there are other times where it is not so clear.

For instance, imagine that types B, C, and D all extend type A, and then a method public A getSomeA() returns an instance of either B, C or D depending on a randomly generated number. The compiler cannot know which exact run-time type will be returned by this method, so if you later cast the results to B, there is no way to know if the cast will succeed (or fail). Therefore the compiler has to assume casts will succeed.

I ran across this while on a hunt for answers myself after attempting to follow a guide using pm2. The goal is to automatically start a node.js application on a server. Some guides call out using pm2 startup systemd, which is the path that leads to the question of using systemctl on Ubuntu 14.04. Instead, use pm2 startup ubuntu.

Take a look at CBFG and the Android port of the loading/rendering code. You should be able to drop the code into your project and use it straight away.

Most of the editors take some kind of shortcut to comment out blocks of code. The default editors use something like command or control and single quote to comment out selected lines of code. In RStudio it's Command or Control+/. Check in your editor.

It's still commenting line by line, but they also uncomment selected lines as well. For the Mac RGUI it's command-option ' (I'm imagining windows is control option). For Rstudio it's just Command or Control + Shift + C again.

These shortcuts will likely change over time as editors get updated and different software becomes the most popular R editors. You'll have to look it up for whatever software you have.

According to the Mysql UPDATE Syntax linked by @CheekySoft, it says right at the bottom.

Currently, you cannot update a table and select from the same table in a subquery.

I guess you are deleting from store_category while still selecting from it in the union.

you can use like this:

string Log_In_Val = (Convert.ToString(attenObj.Log_In) == "" ? "Null" + "," : "'" + Convert.ToString(attenObj.Log_In) + "',");

No, you can not do Insert/Update/Delete.

Functions only work with select statements. And it has only READ-ONLY Database Access.

In addition:

• Functions compile every time.
• Functions must return a value or result.
• Functions only work with input parameters.
• Try and catch statements are not used in functions.

Merge them in two steps, df1 and df2 first, and then the result of that to df3.

In [33]: s1 = pd.merge(df1, df2, how='left', on=['Year', 'Week', 'Colour'])

I dropped year from df3 since you don't need it for the last join.

In [39]: df = pd.merge(s1, df3[['Week', 'Colour', 'Val3']],
                       how='left', on=['Week', 'Colour'])

In [40]: df

   Year Week Colour  Val1  Val2 Val3

XAML:

<ComboBox Height="23" HorizontalAlignment="Left" Margin="19,123,0,0" Name="comboBox1" VerticalAlignment="Top" Width="33" ItemsSource="{Binding}" AllowDrop="True" AlternationCount="1">
    <ComboBoxItem Content="1" Name="ComboBoxItem1" />
    <ComboBoxItem Content="2" Name="ComboBoxItem2" />
    <ComboBoxItem Content="3" Name="ComboBoxItem3" />
</ComboBox>

C#:

if (ComboBoxItem1.IsSelected)
{
    // Your code
}
else if (ComboBoxItem2.IsSelected)
{
    // Your code
}
else if(ComboBoxItem3.IsSelected)
{
    // Your code
}

A simple way to think about it is using even plainer English

If Bool1 And Bool2 Then
If [both are true] Then


If Bool1 AndAlso Bool2 Then
If [first is true then evaluate the second] Then

First save all IDs and alter them programmatically to the values you wan't, then remove them from database and then insert them again using something similar:

use [Name.Database]
go
set identity_insert [Test] ON
insert into [dbo].[Test]
           ([Id])
     VALUES
           (2)
set identity_insert [Test] OFF

For bulk insert use:

use [Name.Database]
go
set identity_insert [Test] ON
BULK INSERT [Test]
FROM 'C:\Users\Oscar\file.csv'
WITH (FIELDTERMINATOR = ';',
      ROWTERMINATOR = '\n',
      KEEPIDENTITY)
set identity_insert [Test] OFF

Sample data from file.csv:

2;
3;
4;
5;
6;

If you don't set identity_insert to off you will get the following error:

Cannot insert explicit value for identity column in table 'Test' when IDENTITY_INSERT is set to OFF.

Are you using platform.system?

 system()
        Returns the system/OS name, e.g. 'Linux', 'Windows' or 'Java'.

        An empty string is returned if the value cannot be determined.

If that isn't working, maybe try platform.win32_ver and if it doesn't raise an exception, you're on Windows; but I don't know if that's forward compatible to 64-bit, since it has 32 in the name.

win32_ver(release='', version='', csd='', ptype='')
        Get additional version information from the Windows Registry
        and return a tuple (version,csd,ptype) referring to version
        number, CSD level and OS type (multi/single
        processor).

But os.name is probably the way to go, as others have mentioned.

if sys.platform == 'win32':
#---------
if os.environ.get('OS','') == 'Windows_NT':
#---------
try: import win32api
#---------
# Emulation using _winreg (added in Python 2.0) and
# sys.getwindowsversion() (added in Python 2.3)
import _winreg
GetVersionEx = sys.getwindowsversion
#----------
def system():

    """ Returns the system/OS name, e.g. 'Linux', 'Windows' or 'Java'.    
        An empty string is returned if the value cannot be determined.   
    """
    return uname()[0]

You can use VLOOKUP, but this requires a wrapper function to return True or False. Not to mention it is (relatively) slow. Use COUNTIF or MATCH instead.

Fill down this formula in column K next to the existing values in column I (from I1 to I2691):

=COUNTIF(<entire column E range>,<single column I value>)>0
=COUNTIF($E$1:$E$99504,$I1)>0

You can also use MATCH:

=NOT(ISNA(MATCH(<single column I value>,<entire column E range>)))
=NOT(ISNA(MATCH($I1,$E$1:$E$99504,0)))

In Place of using this

MsgBox(json.SelectToken("Venue").SelectToken("ID"))

You can also use

MsgBox(json.SelectToken("Venue.ID"))

the simplest way I can think to explain this is by using some pseudo code

so

list of 1, 2 ,3
for each item in list
    templist.Add(item)
    for each item2 in list
        if item2 is Not item
            templist.add(item)
               for each item3 in list
                   if item2 is Not item
                      templist.add(item)

                   end if
               Next
            end if

    Next
    permanentListofPermutaitons,add(templist)
    tempList.Clear()
Next

Now obviously this is not the most flexible way to do this, and doing it recursively would be a lot more functional by my tired sunday night brain doesn't want to think about that at this moment. If no ones put up a recursive version by the morning I'll do one.

There are a few ways:

Double brace initialization

This is a technique which creates an anonymous inner class which has an instance initializer which adds Strings to itself when an instance is created:

Set<String> s = new HashSet<String>() {{
    add("a");
    add("b");
}}

Keep in mind that this will actually create an new subclass of HashSet each time it is used, even though one does not have to explicitly write a new subclass.

A utility method

Writing a method that returns a Set which is initialized with the desired elements isn't too hard to write:

public static Set<String> newHashSet(String... strings) {
    HashSet<String> set = new HashSet<String>();

    for (String s : strings) {
        set.add(s);
    }
    return set;
}

The above code only allows for a use of a String, but it shouldn't be too difficult to allow the use of any type using generics.

Use a library

Many libraries have a convenience method to initialize collections objects.

For example, Google Collections has a Sets.newHashSet(T...) method which will populate a HashSet with elements of a specific type.

Make sure you are running the test as a superuser.

sudo nginx -t

Or the test wont have all the permissions needed to complete the test properly.

Don't define variables in headers. Put declarations in header and definitions in one of the .c files.

In config.h

extern const char *names[];

In some .c file:

const char *names[] =
    {
        "brian", "stefan", "steve"
    };

If you put a definition of a global variable in a header file, then this definition will go to every .c file that includes this header, and you will get multiple definition error because a varible may be declared multiple times but can be defined only once.

My favorite smtp server is hMailServer.

It has a nice windows friendly installer and wizard. Hands down the easiest mail server I've ever setup.

It can proxy through your gmail/yahoo/etc account or send email directly.

Once it is installed, email in xampp just works with no config changes.

Do you want to get the number of rows?

SELECT columnName, COUNT(*) AS row_count
FROM eventsTable
WHERE columnName = 'Business'
GROUP BY columnName

You seem to have the quote marks (") embedded in your string at the start and the end. These are not needed and are illegal characters in a path. How are you initializing the string with the path?

This can be seen from the debugger visualizer, as the string starts with "\" and ends with \"", it shows that the quotes are part of the string, when they shouldn't be.

You can do two thing - a regular escaped string (using \) or a verbatim string literal (that starts with a @):

  string str = "C:\\Program Files (x86)\\test software\\myapp\\demo.exe";

Or:

  string verbatim = @"C:\Program Files (x86)\test software\myapp\demo.exe";

So ... more digging, with the result. It seems that although I ran one process normal and one "As Administrator", I had UAC off. Turning UAC to medium allowed me to see different results. Basically, it all boils down to integrity levels, which are 5.

Browsers, for example, run at Low Level (1), while services (System user) run at System Level (4). Everything is very well explained in Windows Integrity Mechanism Design . When UAC is enabled, processes are created with Medium level (SID S-1-16-8192 AKA 0x2000 is added) while when "Run as Administrator", the process is created with High Level (SID S-1-16-12288 aka 0x3000).

So the correct ACCESS_TOKEN for a normal user (Medium Integrity level) is:

0:000:x86> !token

The difference is, re.match() misleads anyone accustomed to Perl, grep, or sed regular expression matching, and re.search() does not. :-)

More soberly, As John D. Cook remarks, re.match() "behaves as if every pattern has ^ prepended." In other words, re.match('pattern') equals re.search('^pattern'). So it anchors a pattern's left side. But it also doesn't anchor a pattern's right side: that still requires a terminating $.

Frankly given the above, I think re.match() should be deprecated. I would be interested to know reasons it should be retained.

Use String.Replace():

http://www.daniweb.com/software-development/java/threads/73139

Example:

Was a MIT licensed header only implementation which was simple enough to add to a project and 4 lines to use.

Technically, you can use StackTrace, but this is very slow and will not give you the answers you expect a lot of the time. This is because during release builds optimizations can occur that will remove certain method calls. Hence you can't be sure in release whether stacktrace is "correct" or not.

Really, there isn't any foolproof or fast way of doing this in C#. You should really be asking yourself why you need this and how you can architect your application, so you can do what you want without knowing which method called it.

There is no float type. Looks like you want float64. You could also use float32 if you only need a single-precision floating point value.

package main

import "fmt"

func main() {
    i := 5
    f := float64(i)
    fmt.Printf("f is %f\n", f)
}

Swift answer: The following code computes the height of your textView.

                let maximumLabelSize = CGSize(width: Double(textView.frame.size.width-100.0), height: DBL_MAX)
                let options = NSStringDrawingOptions.TruncatesLastVisibleLine | NSStringDrawingOptions.UsesLineFragmentOrigin
                let attribute = [NSFontAttributeName: textView.font!]
                let str = NSString(string: message)
                let labelBounds = str.boundingRectWithSize(maximumLabelSize,
                    options: NSStringDrawingOptions.UsesLineFragmentOrigin,
                    attributes: attribute,
                    context: nil)
                let myTextHeight = CGFloat(ceilf(Float(labelBounds.height)))

Now you can set the height of your textView to myTextHeight

Instead of printf("Error");, you should try perror("Error") which may print the actual reason of failure (like Permission Problem, Invalid Argument, etc).

Use ./catalina.sh start to start Tomcat. Do ./catalina.sh to get the usage.

I am using apache-tomcat-6.0.36.

I don't think that this is safe because e.g. the "=" character is used in raw base 64 and is also used in differentiating the parameters from the values in an HTTP GET.

app.factory('persistObject', function () {

        var persistObject = [];

        function set(objectName, data) {
            persistObject[objectName] = data;
        }
        function get(objectName) {
            return persistObject[objectName];
        }

        return {
            set: set,
            get: get
        }
    });

Fill it with data like this

persistObject.set('objectName', data); 

Get the object data like this

persistObject.get('objectName');

Both "arrA" & "arrB" can be accessed (print it out). However, can't get a size of "arrB".

What is a problem there?

1. Is 'char[]' incomplete type? or
2. 'sizeof' does not accept the extern variable/ label?

In my program, "arrA" & "arrB" are constant lists and fixed before to compile. I would like to use a label(let me easy to maintenance & save RAM memory).

The Simplest GitHub Pull Request is from the web interface without using git.

1. Register a GitHub account, login then go to the page in the repository you want to change.

2. Click the pencil icon,

   

   search for text near the location, make any edits you want then preview them to confirm. Give the proposed change a description up to 50 characters and optionally an extended description then click the Propose file Change button.

3. If you're reading this you won't have write access to the repository (project folders) so GitHub will create a copy of the repository (actually a branch) in your account. Click the Create pull request button.

4. Give the Pull Request a description and add any comments then click Create pull request button.

Improving / Adding more functionality to Ali's answer from earlier, I created a util method in Typescript that suited my needs for this issue. This version returns rotation in degrees that you might also need for your project.

you cannot set this in javascript, you have to do this with html/css:

</style>

EDIT: See this Question and the accepted answer for more information on browser support: Is @Page { size:landscape} obsolete?

In addition to using the mentioned jconsole/visualvm, you can use jstack -l <vm-id> on another command line window, and capture that output.

The <vm-id> can be found using the task manager (it is the process id on windows and unix), or using jps.

Both jstack and jps are include in the Sun JDK version 6 and higher.

I think this is important to consider for cross-platform execution, i.e. as a CYA. :)

On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files. Be very careful to use binary mode when reading and writing such files. On Unix, it doesn’t hurt to append a 'b' to the mode, so you can use it platform-independently for all binary files.

This is directly quoted from Python Software Foundation 2.7.x.

In my case I had to "CD" (Change Directory) to the proper directory first, before calling the command, since the executable I was calling was in my project directory.

Example:

cd "$(SolutionDir)"
call "$(SolutionDir)build.bat"

You can also use a Power Shell script:

$smtp = new-object Net.Mail.SmtpClient("mail.example.com")

if( $Env:SmtpUseCredentials -eq "true" ) {
    $credentials = new-object Net.NetworkCredential("username","password")
    $smtp.Credentials = $credentials
}
$objMailMessage = New-Object System.Net.Mail.MailMessage
$objMailMessage.From = "[email protected]"
$objMailMessage.To.Add("[email protected]")
$objMailMessage.Subject = "eMail subject Notification"
$objMailMessage.Body = "Hello world!"

$smtp.send($objMailMessage)

I did it by adding a point to my initial arrays. In this way I avoid defining self-made functions, and the linear extrapolation (in the example below: right extrapolation) looks ok.

import numpy as np  
from scipy import interp as itp  

xnew = np.linspace(0,1,51)  
x1=xold[-2]  
x2=xold[-1]  
y1=yold[-2]  
y2=yold[-1]  
right_val=y1+(xnew[-1]-x1)*(y2-y1)/(x2-x1)  
x=np.append(xold,xnew[-1])  
y=np.append(yold,right_val)  
f = itp(xnew,x,y)  

I think it's just daw

daw - delete a word

check before delete the user otherwise throws error exeption

$user=User::find($request->id);
  
   if($user)
   {
   // return $user;           <------------------------user exist
       if($user->delete()){
         return 'user deleted';
         }
    else{
       return "something wrong";
        }   

   }
  else{
     return "user not exist";// <--------------------user not exist
    }

Standard C++ has no notion of 'colors'. So what you are asking depends on the operating system.

For Windows, you can check out the SetConsoleTextAttribute function.

On *nix, you have to use the ANSI escape sequences.

Kotlin version of @Swapnil Kotwal's answer.

Android Studio 4.0.1, Kotlin 1.3.72

val greenText = SpannableString("This is green,")
greenText.setSpan(ForegroundColorSpan(resources.getColor(R.color.someGreenColor), null), 0, greenText.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
yourTextView.text = greenText

val yellowText = SpannableString("this is yellow, ")
yellowText.setSpan(ForegroundColorSpan(resources.getColor(R.color.someYellowColor), null), 0, yellowText.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
yourTextView.append(yellowText)

val redText = SpannableString("and this is red.")
redText.setSpan(ForegroundColorSpan(resources.getColor(R.color.someRedColor), null), 0, redText.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
yourTextView.append(redText)

History.

The earliest versions of Unix time had a 32-bit integer incrementing at a rate of 60 Hz, which was the rate of the system clock on the hardware of the early Unix systems. The value 60 Hz still appears in some software interfaces as a result. The epoch also differed from the current value. The first edition Unix Programmer's Manual dated November 3, 1971 defines the Unix time as "the time since 00:00:00, Jan. 1, 1971, measured in sixtieths of a second".

Another way of doing this is using the basePackages field; which is a field inside ComponentScan annotation.

@ComponentScan(basePackages={"com.firstpackage","com.secondpackage"})

If you look into the ComponentScan annotation .class from the jar file you will see a basePackages field that takes in an array of Strings

public @interface ComponentScan {
String[] basePackages() default {};
}

Or you can mention the classes explicitly. Which takes in array of classes

Class<?>[]  basePackageClasses

Try this to convert string to uri

String mystring="Hello"
Uri myUri = Uri.parse(mystring);

Uri to String

Uri uri;
String uri_to_string;
uri_to_string= uri.toString();

Do you mean you want Class C to be the base class for A & B in that case.

public abstract class C
{
    public abstract void Method1();

    public abstract void Method2();
}

public class A : C
{
    public override void Method1()
    {
        throw new NotImplementedException();
    }

    public override void Method2()
    {
        throw new NotImplementedException();
    }
}


public class B : C
{
    public override void Method1()
    {
        throw new NotImplementedException();
    }

    public override void Method2()
    {
        throw new NotImplementedException();
    }
}

Technically you can write code in a .NET language and use the Mono Framework (http://www.mono-project.com/) to run it on the iPhone. I haven't ever seen someone do this from scratch, but the folks that write the Unity Game Development platform (http://unity3d.com/) use it to make their games iPhone-compatible. The game itself is written in .NET, and then they provide an iPhone shell with the Mono frameworks that allows everything to run on the iPhone. I don't know whether they've contributed all of their modifications to Mono back to the open-source repository, but if you're serious about writing iPhone apps outside the Mac environment, it might be possible.

That said, I think you could dump weeks into getting that to work, and it might be best to invest in a Mac instead :-)

This function tells the entity referenced by REF that it is now an object in the CLASSNAME package, or the current package if CLASSNAME is omitted. Use of the two-argument form of bless is recommended.

Example:

bless REF, CLASSNAME
bless REF

Return Value

This function returns the reference to an object blessed into CLASSNAME.

Example:

Following is the example code showing its basic usage, the object reference is created by blessing a reference to the package's class -

#!/usr/bin/perl

package Person;
sub new
{
    my $class = shift;
    my $self = {
        _firstName => shift,
        _lastName  => shift,
        _ssn       => shift,
    };
    # Print all the values just for clarification.
    print "First Name is $self->{_firstName}\n";
    print "Last Name is $self->{_lastName}\n";
    print "SSN is $self->{_ssn}\n";
    bless $self, $class;
    return $self;
}

You can pass in the data to be used in the mouseover like this- the mouseover event uses a function with your previously entered data as an argument (and the index as a second argument) so you don't need to use enter() a second time.

vis.selectAll("circle")
.data(datafiltered).enter().append("svg:circle")
.attr("cx", function(d) { return x(d.x);})
.attr("cy", function(d) {return y(d.y)})
.attr("fill", "red").attr("r", 15)
.on("mouseover", function(d,i) {
    d3.select(this).append("text")
        .text( d.x)
        .attr("x", x(d.x))
        .attr("y", y(d.y)); 
});

Note: If you know Key, use this code

String value=meMap.get(key);

You could google for PDF viewer component, and come up with more than a few hits.

If you don't really need to embed them in your app, though - you can just require Acrobat Reader or FoxIt (or bundle it, if it meets their respective licensing terms) and shell out to it. It's not as cool, but it gets the job done for free.

Honestly, I had problems with bundler circular dependencies and the best way to go is rm -rf .bundle. Save yourselves the headache and just use the hammer.

I am using this.

s = s.replaceAll("\\W", ""); 

It replace all special characters from string.

Here

\w : A word character, short for [a-zA-Z_0-9]

\W : A non-word character

This article helped explain a lot of things. It's in FAQ style.

Async/Await FAQ

This part explains why Thread.Sleep runs on the same original thread - leading to my initial confusion.

Does the “async” keyword cause the invocation of a method to queue to the ThreadPool? To create a new thread? To launch a rocket ship to Mars?

No. No. And no. See the previous questions. The “async” keyword indicates to the compiler that “await” may be used inside of the method, such that the method may suspend at an await point and have its execution resumed asynchronously when the awaited instance completes. This is why the compiler issues a warning if there are no “awaits” inside of a method marked as “async”.

You can add whatever headers you need to the HttpClient.

Here is a nice tutorial about it.

This doesn't just reference to POST-requests, you can also use it for GET-requests.

You could simply have the function "remove itself"

?function Once(){
    console.log("run");

    Once = undefined;
}

Once();  // run
Once();  // Uncaught TypeError: undefined is not a function 

But this may not be the best answer if you don't want to be swallowing errors.

You could also do this:

function Once(){
    console.log("run");

    Once = function(){};
}

Once(); // run
Once(); // nothing happens

I need it to work like smart pointer, if there no elements from type A it can be executed, if there is one or more A elements the function can't be executed.

function Conditional(){
    if (!<no elements from type A>) return;

    // do stuff
}

<a href="delete.php?id=22" onclick = "if (! confirm('Continue?')) { return false; }">Confirm OK, then goto URL (uses onclick())</a>

Unless you are writing very small files, you should probably use templates.

Example:

- name: copy upstart script
  template: 
    src: myCompany-service.conf.j2 
    dest: "/etc/init/myCompany-service.conf"

This thread caught my attention since it deals with a simple problem that requires a lot of work (CPU cycles) even for a modern CPU. And one day I also stood there with the same ¤#%"#" problem. I had to flip millions of bytes. However I know all my target systems are modern Intel-based so let's start optimizing to the extreme!!!

So I used Matt J's lookup code as the base. the system I'm benchmarking on is a i7 haswell 4700eq.

Matt J's lookup bitflipping 400 000 000 bytes: Around 0.272 seconds.

I then went ahead and tried to see if Intel's ISPC compiler could vectorise the arithmetics in the reverse.c.

I'm not going to bore you with my findings here since I tried a lot to help the compiler find stuff, anyhow I ended up with performance of around 0.15 seconds to bitflip 400 000 000 bytes. It's a great reduction but for my application that's still way way too slow..

So people let me present the fastest Intel based bitflipper in the world. Clocked at:

Time to bitflip 400000000 bytes: 0.050082 seconds !!!!!

    printf ("\r\nData in(start):\r\n");
    for (unsigned int j = 0; j < 4; j++)
    {
        for (unsigned int i = 0; i < DISPLAY_WIDTH; i++)
        {
            printf ("0x%02x,",data[i+(j*DISPLAY_WIDTH)]);
        }
        printf ("\r\n");
    }

    printf ("\r\nNumber of 32-byte chunks to convert: %d\r\n",(unsigned int)ceil(NUM_DATA_BYTES/32.0));

    double start_time = omp_get_wtime();
    bitflipbyte(data,(unsigned int)ceil(NUM_DATA_BYTES/32.0),k1);
    double end_time = omp_get_wtime();

    printf ("\r\nData out:\r\n");
    for (unsigned int j = 0; j < 4; j++)

    // return with no errors
    return 0;
}

The printf's are for debugging..

Here is the workhorse:

bits 64
global bitflipbyte

bitflipbyte:    
        vmovdqa     ymm2, [rdx]
        add         rdx, 20h
        vmovdqa     ymm3, [rdx]
        add         rdx, 20h
        vmovdqa     ymm4, [rdx]
bitflipp_loop:
        vmovdqa     ymm0, [rdi] 
        vpand       ymm1, ymm2, ymm0 
        vpandn      ymm0, ymm2, ymm0 
        vpsrld      ymm0, ymm0, 4h 
        vpshufb     ymm1, ymm4, ymm1 
        vpshufb     ymm0, ymm3, ymm0         
        vpor        ymm0, ymm0, ymm1
        vmovdqa     [rdi], ymm0
        add     rdi, 20h
        dec     rsi
        jnz     bitflipp_loop
        ret

The code takes 32 bytes then masks out the nibbles. The high nibble gets shifted right by 4. Then I use vpshufb and ymm4 / ymm3 as lookup tables. I could use a single lookup table but then I would have to shift left before ORing the nibbles together again.

There are even faster ways of flipping the bits. But I'm bound to single thread and CPU so this was the fastest I could achieve. Can you make a faster version?

Please make no comments about using the Intel C/C++ Compiler Intrinsic Equivalent commands...

I'm assuming you're using XML layout.

<TextView  
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:gravity="center"
    android:text="@string/**yourtextstring**"
/>

You can also use gravity center_vertical or center_horizontal according to your need.

and as @stealthcopter commented in java: .setGravity(Gravity.CENTER);

Yes, it can be done as long as both windows are on the same domain. The window.open() function will return a handle to the new window. The child window can access the parent window using the DOM element "opener".

You can use :

1. git stash to save your work
2. git checkout <your-branch>
3. git stash apply or git stash pop to load your last work

Git stash extremely useful when you want temporarily save undone or messy work, while you want to doing something on another branch.

git -stash documentation

Think of onload like any other attribute. On an input box, for example, you could put:

<input id="test1" value="something"/>

Or you could call:

document.getElementById('test1').value = "somethingelse";

The onload attribute works the same way, except that it takes a function as its value instead of a string like the value attribute does. That also explains why you can "only use one of them" - calling window.onload reassigns the value of the onload attribute for the body tag.

Also, like others here are saying, usually it is cleaner to keep style and javascript separated from the content of the page, which is why most people advise to use window.onload or like jQuery's ready function.

Here is what worked for me:

render() {
  const { styleValue } = this.props;
  const dynamicStyleUpdatedFromProps = {
    height: styleValue,
    width: styleValue,
    borderRadius: styleValue,
  }

  return (
    <View style={{ ...styles.staticStyleCreatedFromStyleSheet, ...dynamicStyleUpdatedFromProps }} />
  );
}

For some reason, this was the only way that mine would update properly.

In case of proxy the SERVER_PORT may not give the correct value so this is what worked for me -

$protocol = ((!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') || $_SERVER['SERVER_PORT'] == 443 || $_SERVER['HTTP_X_FORWARDED_PORT'] == 443) ? "https://" : "http://"

Try

margin: 0 auto;
display:table

Hope that helps somebody out.

This returns all xml-files recursively :

var allFiles = Directory.GetFiles(path, "*.xml", SearchOption.AllDirectories);

It's a late answer but now there is an easy way. Current version of jquery lets you search if attribute exists. For example

$('[id]')

will give you all the elements if they have id. If you want all spans with id starting with span you can use

$('span[id^="span"]')

Just write <a href="#"></a>.

If that's what you want, you don't need a server-side control.

If someone is still interested in how to validate zip codes I've found a solution:

Using Google Geocoding API we can check validity of ZIP code having both Country code and a ZIP code itself.

For example I live in Ukraine so I can check like this: https://maps.googleapis.com/maps/api/geocode/json?components=postal_code:80380|country:UA

Or using JS API: https://developers.google.com/maps/documentation/javascript/geocoding#ComponentFiltering

Where 80380 is valid ZIP for Ukraine, actually every (#####) is valid.

Google returns ZERO_RESULTS status if nothing found. Or OK and a result if both are correct.

Hope this will be helpful.

1. Switch to Branch2

   git checkout Branch2
   

2. Apply the current (Branch2) changes on top of the Branch1 changes, staying in Branch2:

   git rebase Branch1
   

Which would leave you with the desired result in Branch2:

a -- b -- c                      <-- Master
           \
            d -- e               <-- Branch1
           \
            d -- e -- f' -- g'   <-- Branch2

You can delete Branch1.

You've got several options:

• Use a different user account, one with execute permissions on that directory.
• Change the permissions on the directory to allow your user account execute permissions.
  • Either use chmod(1) to change the permissions or
  • Use the setfacl(1) command to add an access control list entry for your user account. (This also requires mounting the filesystem with the acl option; see mount(8) and fstab(5) for details on the mount parameter.)

It's impossible to suggest the correct approach without knowing more about the problem; why are the directory permissions set the way they are? Why do you need access to that directory?

You are making sense, but you seem to misunderstand the concept of sending emails.

HTML is parsed on the client side, while the e-mail needs to be sent from the server. You cannot do it in pure HTML. I would suggest writing a PHP script that will deal with the email sending for you.

Basically, instead of the MAILTO, your form's action will need to point to that PHP script. In the script, retrieve the values passed by the form (in PHP, they are available through the $_POST superglobal) and use the email sending function (mail()).

Of course, this can be done in other server-side languages as well. I'm giving a PHP solution because PHP is the language I work with.

A simple example code:

form.html:

<form method="post" action="email.php">
    <input type="text" name="subject" /><br />
    <textarea name="message"></textarea>
</form>

email.php:

<?php
    mail('[email protected]', $_POST['subject'], $_POST['message']);
?>
<p>Your email has been sent.</p>

Of course, the script should contain some safety measures, such as checking whether the $_POST valies are at all available, as well as additional email headers (sender's email, for instance), perhaps a way to deal with character encoding - but that's too complex for a quick example ;).

You can do all that by using just one RelativeLayout (which, btw, don't need android:orientation parameter). So, instead of having a LinearLayout, containing a bunch of stuff, you can do something like:

<RelativeLayout>
    <ImageButton
        android:layout_width="wrap_content"
        android:id="@+id/the_first_one"
        android:layout_alignParentLeft="true"/>
    <ImageButton
        android:layout_width="wrap_content"
        android:layout_toRightOf="@+id/the_first_one"/>
    <ImageButton
        android:layout_width="wrap_content"
        android:layout_alignParentRight="true"/>
</RelativeLayout>

As you noticed, there are some XML parameters missing. I was just showing the basic parameters you had to put. You can complete the rest.

Yes, there is a module fs-extra. There is a method .emptyDir() inside this module which does the job. Here is an example:

const fsExtra = require('fs-extra')

fsExtra.emptyDirSync(fileDir)

There is also an asynchronous version of this module too. Anyone can check out the link.

This test shows three blocks of two blocks together on the same line.

.group {
    display:block;
    box-sizing:border-box;
}
.group>div {
    display:inline-block;
    padding-bottom:4px;
}
.group>div>span,.group>div>div {
    width:200px;
    height:40px;
    text-align: center;
    padding-top:20px;
    padding-bottom:0px;
    display:inline-block;
    border:1px solid black;
    background-color:blue;
    color:white;
}

input[type=text] {
    height:1em;
}

<div class="group">
    <div>
        <span>First Name</span>
        <span><input type="text"/></span>
    </div>
    <div>
        <div>Last Name</div>
        <div><input type="text"/></div>
    </div>
    <div>
        <div>Address</div>
        <div><input type="text"/></div>
    </div>
</div>

Try using this instead:

var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();

It's bit hard to navigate Google's api but here is the relevant documentation.

One thing I had trouble finding was how to go in the other direction. From coordinates to an address. Here is the code I neded upp using. Please not that I also use jquery.

$.each(results[0].address_components, function(){
    $("#CreateDialog").find('input[name="'+ this.types+'"]').attr('value', this.long_name);
});

What I'm doing is to loop through all the returned address_components and test if their types match any input element names I have in a form. And if they do I set the value of the element to the address_components value.
If you're only interrested in the whole formated address then you can follow Google's example

Portable HttpClient for .NET Framework and Windows Phone

see paragraph Using HttpClient on .NET Framework 4.0 or Windows Phone 7.5 http://blogs.msdn.com/b/bclteam/archive/2013/02/18/portable-httpclient-for-net-framework-and-windows-phone.aspx

What you have is correct, though you will not call it global, it is a class attribute and can be accessed via class e.g Shape.lolwut or via an instance e.g. shape.lolwut but be careful while setting it as it will set an instance level attribute not class attribute

class Shape(object):
    lolwut = 1

shape = Shape()

print Shape.lolwut,  # 1
print shape.lolwut,  # 1

# setting shape.lolwut would not change class attribute lolwut 
# but will create it in the instance
shape.lolwut = 2

print Shape.lolwut,  # 1
print shape.lolwut,  # 2

# to change class attribute access it via class
Shape.lolwut = 3

print Shape.lolwut,  # 3
print shape.lolwut   # 2 

output:

1 1 1 2 3 2

Somebody may expect output to be 1 1 2 2 3 3 but it would be incorrect

This is how I got it working on httpClient 4.5 (as per Olive Tree request):

CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(
        new AuthScope(AuthScope.ANY_HOST, 443),
        new UsernamePasswordCredentials(this.user, this.password));

SSLContext sslContext = SSLContexts.createDefault();

SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext,
        new String[]{"TLSv1", "TLSv1.1"},
        null,
        new NoopHostnameVerifier());

CloseableHttpClient httpclient = HttpClients.custom()
        .setDefaultCredentialsProvider(credsProvider)
        .setSSLSocketFactory(sslsf)
        .build();

return httpclient;

If you want load image with a local relative URL as you are doing. React project has a default public folder. You should put your images folder inside. It will work.

Use filter, or if the number of dictionaries in exampleSet is too high, use ifilter of the itertools module. It would return an iterator, instead of filling up your system's memory with the entire list at once:

from itertools import ifilter
for elem in ifilter(lambda x: x['type'] in keyValList, exampleSet):
    print elem

My current work machine came with bitlocker, and being an upgrade from the prior model. It only seemed faster to me. What I have found, however, is that bitlocker is more bullet proof than truecrypt, when it comes to accurately laying down the data. I do a lot of work in SAS which constantly writes backup copies to disk as it moves along and shoots a variety of output types to disk at the end. SAS works fine writing output from multithreaded processes back to bitlocker and doesn't seem to know it's there. This has not been the case for me with truecrypt. I'm not sure what happens or how, but I found that processes got out of synch when working with source/output data in a truecrypt container, which is what I installed on my second work computer since it had no bitlocker. The constant backups were shooting to an SSD while the truecrypt results were on a regular HD. Maybe that speed difference helped trip it up. Whatever the cause, I had to quit using truecrypt on that second computer because it made my SAS results out of synch with respect to processing order and it screwed up some of my processes and data. Scary stuff in my world.

I work with people who have successfully used Truecrypt on the exact same computer, but they weren't using a disk intensive app. like SAS.

Bitlocker to Go, the encryption which bitlocker applies to thumb-drives, does slow things down quite a bit when it comes to read/write times. It's not too hard to use as long as you remember your password on the thumbdrive, and are willing to wait for it to format/initialize the drive, but in my experience it made access to the flash drive about 4 times as slow. Don't know why it would slow down a thumb drive and not a disk but that's how it was for me and my coworker.

Based on my success with bitlocker at work, I bought Windows Pro for my home computer to get bitlocker and plan to encrypt some directories with it for things like financials.

window.alert = null;
alert('test'); // fail
delete window.alert; // true
alert('test'); // win

window is an instance of DOMWindow, and by setting something to window.alert, the correct implementation is being "shadowed", i.e. when accessing alert it is first looking for it on the window object. Usually this is not found, and it then goes up the prototype chain to find the native implementation. However, when manually adding the alert property to window it finds it straight away and does not need to go up the prototype chain. Using delete window.alert you can remove the window own property and again expose the prototype implementation of alert. This may help explain:

window.hasOwnProperty('alert'); // false
window.alert = null;
window.hasOwnProperty('alert'); // true
delete window.alert;
window.hasOwnProperty('alert'); // false

The typical approach is to use select() to wait until data is available or until the timeout occurs. Only call recv() when data is actually available. To be safe, we also set the socket to non-blocking mode to guarantee that recv() will never block indefinitely. select() can also be used to wait on more than one socket at a time.

import select

mysocket.setblocking(0)

ready = select.select([mysocket], [], [], timeout_in_seconds)
if ready[0]:
    data = mysocket.recv(4096)

If you have a lot of open file descriptors, poll() is a more efficient alternative to select().

Another option is to set a timeout for all operations on the socket using socket.settimeout(), but I see that you've explicitly rejected that solution in another answer.

You will need a custom class loader for this, have a look at One Jar.

One-JAR lets you package a Java application together with its dependency Jars into a single executable Jar file.

It has an ant task which can simplify the building of it as well.

REFERENCE (from background)

Most developers reasonably assume that putting a dependency Jar file into their own Jar file, and adding a Class-Path attribute to the META-INF/MANIFEST will do the trick:

jarname.jar
| /META-INF
| |  MANIFEST.MF
| |    Main-Class: com.mydomain.mypackage.Main
| |    Class-Path: commons-logging.jar
| /com/mydomain/mypackage
| |  Main.class
| commons-logging.jar

Unfortunately this is does not work. The Java Launcher$AppClassLoader does not know how to load classes from a Jar inside a Jar with this kind of Class-Path. Trying to use jar:file:jarname.jar!/commons-logging.jar also leads down a dead-end. This approach will only work if you install (i.e. scatter) the supporting Jar files into the directory where the jarname.jar file is installed.

Copy =VLOOKUP(M3,A$2:Q$47,13,FALSE) to other sheets, then search for ! replace by !$, search for : replace by :$ one time for all sheets

Here is the way that I've followed,

int[] selRows = ((GridView)gridControl1.MainView).GetSelectedRows();
DataRowView selRow = (DataRowView)(((GridView)gridControl1.MainView).GetRow(selRows[0]));
txtName.Text = selRow["name"].ToString();

Also you can iterate through selected rows using the selRows array. Here the code describes how to get data only from first selected row. You can insert these code lines to click event of the grid.

We just had a similar issue, looks like the user reset his password on Friday and over the weekend and on Monday he kept getting locked out.

Turned out to be he forgot to update his password on his mobile phone.

wll it looks like I found the answer, although I havent tested it yet

var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
saveAs(blob, "hello world.txt");

from this page https://github.com/eligrey/FileSaver.js

I am surprised the code answer is not posted already, it's a one liner.

You could just {{ categeory_id | getVariations }}

It's a one-liner:

$twig->addFilter('getVariations', new Twig_Filter_Function('getVariations'));

I am using both JavaScript Cookie and Java CookieUtil in my project, below settings solved my problem:

var expires = "expires=" + d.toGMTString();         
document.cookie = "visitName" + "=Hailin;" + expires + ";path=/;SameSite=None;Secure"; //can set SameSite=Lax also

JAVA Cookie (set proxy_cookie_path in Nginx)

location / {
   proxy_pass http://96.xx.xx.34;
