You are dealing with a HttpPostedFile; this is the file that is "uploaded" to the web server. You really need to save that file somewhere and then use it, because...

...in your instance, it just so happens to be that you are hosting your website on the same machine the file resides, so the path is accessible. As soon as you deploy your site to a different machine, your code isn't going to work.

Break this down into two steps:

1) Save the file somewhere - it's very common to see this:

string saveFolder = @"C:\temp\uploads"; //Pick a folder on your machine to store the uploaded files

string filePath = Path.Combine(saveFolder, FileUpload1.FileName); 

FileUpload1.SaveAs(filePath);

Now you have your file locally and the real work can be done.

2) Get the data from the file. Your code should work as is but you can simply write your connection string this way:

string excelConnString = String.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties="Excel 12.0";", filePath);

You can then think about deleting the file you've just uploaded and imported.

To provide a more concrete example, we can refactor your code into two methods:

    private void SaveFileToDatabase(string filePath)
    {
        String strConnection = "Data Source=.\\SQLEXPRESS;AttachDbFilename='C:\\Users\\Hemant\\documents\\visual studio 2010\\Projects\\CRMdata\\CRMdata\\App_Data\\Database1.mdf';Integrated Security=True;User Instance=True";

        String excelConnString = String.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=\"Excel 12.0\"", filePath);
        //Create Connection to Excel work book 
        using (OleDbConnection excelConnection = new OleDbConnection(excelConnString))
        {
            //Create OleDbCommand to fetch data from Excel 
            using (OleDbCommand cmd = new OleDbCommand("Select [ID],[Name],[Designation] from [Sheet1$]", excelConnection))
            {
                excelConnection.Open();
                using (OleDbDataReader dReader = cmd.ExecuteReader())
                {
                    using(SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection))
                    {
                        //Give your Destination table name 
                        sqlBulk.DestinationTableName = "Excel_table";
                        sqlBulk.WriteToServer(dReader);
                    }
                }
            }
        } 
    }


    private string GetLocalFilePath(string saveDirectory, FileUpload fileUploadControl)
    {


        string filePath = Path.Combine(saveDirectory, fileUploadControl.FileName);

        fileUploadControl.SaveAs(filePath);

        return filePath;

    }

You could simply then call SaveFileToDatabase(GetLocalFilePath(@"C:\temp\uploads", FileUpload1));

Consider reviewing the other Extended Properties for your Excel connection string. They come in useful!

Other improvements you might want to make include putting your Sql Database connection string into config, and adding proper exception handling. Please consider this example for demonstration only!

How to address your textbox depends on the HTML-code:

<!-- 1 --><input type="textbox" id="Tue" />
<!-- 2 --><input type="textbox" name="Tue" />

If you use the 'id' attribute:

var textbox = document.getElementById('Tue');

for 'name':

var textbox = document.getElementsByName('Tue')[0]

(Note that getElementsByName() returns all elements with the name as array, therefore we use [0] to access the first one)

Then, use the 'value' attribute:

textbox.value = 'Foobar';

for detail info, let's say the code below will make a div aligned center:

margin-left: auto;
margin-right: auto;

or simply use:

margin: 0 auto;

but bear in mind, the above CSS code only works when you specify a fixed width (not 100%) on your html element. so the complete solution for your issue would be:

.your-inner-div {
      margin: 0 auto;
      width: 900px;
}

To index on any criteria, you can so something like the following:

In [1]: from numpy import *
In [2]: x = arange(125).reshape((5,5,5))
In [3]: y = indices(x.shape)
In [4]: locs = y[:,x >= 120] # put whatever you want in place of x >= 120
In [5]: pts = hsplit(locs, len(locs[0]))
In [6]: for pt in pts:
   .....:         print(', '.join(str(p[0]) for p in pt))
4, 4, 0
4, 4, 1
4, 4, 2
4, 4, 3
4, 4, 4

And here's a quick function to do what list.index() does, except doesn't raise an exception if it's not found. Beware -- this is probably very slow on large arrays. You can probably monkey patch this on to arrays if you'd rather use it as a method.

def ndindex(ndarray, item):
    if len(ndarray.shape) == 1:
        try:
            return [ndarray.tolist().index(item)]
        except:
            pass
    else:
        for i, subarray in enumerate(ndarray):
            try:
                return [i] + ndindex(subarray, item)
            except:
                pass

In [1]: ndindex(x, 103)
Out[1]: [4, 0, 3]

I have a 7GB SQLite database. To perform a particular query with an inner join takes 2.6s In order to speed this up I tried adding indexes. Depending on which index(es) I added, sometimes the query went down to 0.1s and sometimes it went UP to as much as 7s. I think the problem in my case was that if a column is highly duplicate then adding an index degrades performance :(

I needed to know this and came here, before I remembered the Environment class.

In case anyone else had this issue, just use this: Environment.CurrentDirectory.

Example:

Dim dataDirectory As String = String.Format("{0}\Data\", Environment.CurrentDirectory)

When run from Visual Studio in debug mode yeilds:

C:\Development\solution folder\application folder\bin\debug

This is the exact behaviour I needed, and its simple and straightforward enough.

This is another way...(with limited range)

public static String numToWord(Integer i) {

 final  String[] units = { "Zero", "One", "Two", "Three",
        "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven",
        "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen",
        "Seventeen", "Eighteen", "Nineteen" };
 final  String[] tens = { "", "", "Twenty", "Thirty", "Forty",
        "Fifty", "Sixty", "Seventy", "Eighty", "Ninety" };
    if (i < 20)
        return units[i];
    if (i < 100)
        return tens[i / 10] + ((i % 10 > 0) ? " " + numToWord(i % 10) : "");
    if (i < 1000)
        return units[i / 100] + " Hundred"
                + ((i % 100 > 0) ? " and " + numToWord(i % 100) : "");
    if (i < 1000000)
        return numToWord(i / 1000) + " Thousand "
                + ((i % 1000 > 0) ? " " + numToWord(i % 1000) : "");
    return numToWord(i / 1000000) + " Million "
            + ((i % 1000000 > 0) ? " " + numToWord(i % 1000000) : "");
}

I believe you can do this using a Unicode encoding, but I doubt this is what you really want.

The == is the unicode value 2A76 so I belive you can do this:

char c = '\u2A76';

I can't test this at the moment but I'd be interested to know if that works for you.

You will need to dig around for the others. Here is a unicode table if you want to look:

http://www.tamasoft.co.jp/en/general-info/unicode.html

Set the class .fill to height: 100%

.fill { 
    min-height: 100%;
    height: 100%;
}

JSFiddle

(I put a red background for #map so you can see it takes up 100% height)

In Symfony 3.3 you can use

$projectRoot = $this->get('kernel')->getProjectDir();

to get the web/project root.

The V1 git man page had a reference about un-applying a stash. The excerpt is below.

The newer V2 git man page doesn't include any reference to un-applying a stash but the below still works well

Un-applying a Stash In some use case scenarios you might want to apply stashed changes, do some work, but then un-apply those changes that originally came from the stash. Git does not provide such a stash un-apply command, but it is possible to achieve the effect by simply retrieving the patch associated with a stash and applying it in reverse:

$ git stash show -p stash@{0} | git apply -R

Again, if you don’t specify a stash, Git assumes the most recent stash:

$ git stash show -p | git apply -R

You may want to create an alias and effectively add a stash-unapply command to your Git. For example:

$ git config --global alias.stash-unapply '!git stash show -p | git apply -R'
$ git stash apply
$ #... work work work
$ git stash-unapply

No regex, so no need for //.

this should work:

$str = str_replace("\\", '/', $str);

You need to escape "\" as well.

Use the serialize method:

$.ajax({
    ...
    data: $("#registerSubmit").serialize(),
    ...
})

Docs: serialize()

I was deploying python Django framework when I got this error because I forget to put my app name web: gunicorn plaindjango.wsgi:application --log-file - instead of plaindjango

Pass the sheet name with the Range parameter of the DoCmd.TransferSpreadsheet Method. See the box titled "Worksheets in the Range Parameter" near the bottom of that page.

This code imports from a sheet named "temp" in a workbook named "temp.xls", and stores the data in a table named "tblFromExcel".

Dim strXls As String
strXls = CurrentProject.Path & Chr(92) & "temp.xls"
DoCmd.TransferSpreadsheet acImport, , "tblFromExcel", _
    strXls, True, "temp!"

A function inside of a function is commonly used for closures.

(There is a lot of contention over what exactly makes a closure a closure.)

Here's an example using the built-in sum(). It defines start once and uses it from then on:

def sum_partial(start):
    def sum_start(iterable):
        return sum(iterable, start)
    return sum_start

In use:

>>> sum_with_1 = sum_partial(1)
>>> sum_with_3 = sum_partial(3)
>>> 
>>> sum_with_1
<function sum_start at 0x7f3726e70b90>
>>> sum_with_3
<function sum_start at 0x7f3726e70c08>
>>> sum_with_1((1,2,3))
7
>>> sum_with_3((1,2,3))
9

Built-in python closure

functools.partial is an example of a closure.

From the python docs, it's roughly equivalent to:

def partial(func, *args, **keywords):
    def newfunc(*fargs, **fkeywords):
        newkeywords = keywords.copy()
        newkeywords.update(fkeywords)
        return func(*(args + fargs), **newkeywords)
    newfunc.func = func
    newfunc.args = args
    newfunc.keywords = keywords
    return newfunc

(Kudos to @user225312 below for the answer. I find this example easier to figure out, and hopefully will help answer @mango's comment.)

I think that the best solution for drawing text in OpenGL is texture fonts, I work with them for a long time. They are flexible, fast and nice looking (with some rear exceptions). I use special program for converting font files (.ttf for example) to texture, which is saved to file of some internal "font" format (I've developed format and program based on http://content.gpwiki.org/index.php/OpenGL:Tutorials:Font_System though my version went rather far from the original supporting Unicode and so on). When starting the main app, fonts are loaded from this "internal" format. Look link above for more information.

With such approach the main app doesn't use any special libraries like FreeType, which is undesirable for me also. Text is being drawn using standard OpenGL functions.

Just <input id="field_name_{{$index}}" />

I threw CMS's excellent answer into a quick jQuery extension:

(function($, window) {
  $.fn.replaceOptions = function(options) {
    var self, $option;

    this.empty();
    self = this;

    $.each(options, function(index, option) {
      $option = $("<option></option>")
        .attr("value", option.value)
        .text(option.text);
      self.append($option);
    });
  };
})(jQuery, window);

It expects an array of objects which contain "text" and "value" keys. So usage is as follows:

var options = [
  {text: "one", value: 1},
  {text: "two", value: 2}
];

$("#foo").replaceOptions(options);

The various answers in this blog seem to be defined by SE's who promote strict adherence to the usual rules of object-oriented programming (use a Public Class with public shared (aka static), and fully-qualified class references, or SE's who promote using the backward-compatibility feature (Module) for which the compiler obviously needs to do the same thing to make it work.

As a SE with 30+ years of experience, I would propose the following guidelines:

1. If you are writing all new code (not attempting to convert a legacy app) that you avoid using these forms altogether except in the rare instance that you really DO need to have a static variable because they can cause terrible consequences (and really hard-to-find bugs). (Multithread and multiprocessing code requires semaphores around static variables...)

2. If you are modifying a small application that already has a few global variables, then formulate them so they are not obscured by Modules, that is, use the standard rules of object-oriented programming to re-create them as public static and access them by full qualification so others can figure out what is going on.

3. If you have a huge legacy application with dozens or hundreds of global variables, by all means, use Modules to define them. There is no reason to waste time when getting the application working, because you are probably already behind the 8-ball in time spent on Properties, etc.

maybe I'd go by this.

 SQL = SELECT REPLACE(myColumn, '""', '\'') FROM myTable

I used singlequotes because that's the one that registers string expressions in MySQL, or so I believe.

Hope that helps.

You can try updating as below:

Syntax: UPDATE table_name SET column_name = column_name::jsonb || '{"key":new_value}' WHERE column_name condition;

For your example:

UPDATE test SET data = data::jsonb || '{"a":new_value}' WHERE data->>'b' = '2';

            UTF8), BUFFER_SIZE);
    String str;
    while ((str = br.readLine()) != null) {

Available fonts (as of Oreo)

The Material Design Typography page has demos for some of these fonts and suggestions on choosing fonts and styles.

For code sleuths: fonts.xml is the definitive and ever-expanding list of Android fonts.

Using these fonts

Set the android:fontFamily and android:textStyle attributes, e.g.

<!-- Roboto Bold -->
<TextView
    android:fontFamily="sans-serif"
    android:textStyle="bold" />

to the desired values from this table:

Font                     | android:fontFamily          | android:textStyle
-------------------------|-----------------------------|-------------------
Roboto Thin              | sans-serif-thin             |
Roboto Light             | sans-serif-light            |
Roboto Regular           | sans-serif                  |
Roboto Bold              | sans-serif                  | bold
Roboto Medium            | sans-serif-medium           |
Roboto Black             | sans-serif-black            |
Roboto Condensed Light   | sans-serif-condensed-light  |
Roboto Condensed Regular | sans-serif-condensed        |
Roboto Condensed Medium  | sans-serif-condensed-medium |
Roboto Condensed Bold    | sans-serif-condensed        | bold
Noto Serif               | serif                       |
Noto Serif Bold          | serif                       | bold
Droid Sans Mono          | monospace                   |
Cutive Mono              | serif-monospace             |
Coming Soon              | casual                      |
Dancing Script           | cursive                     |
Dancing Script Bold      | cursive                     | bold
Carrois Gothic SC        | sans-serif-smallcaps        |

(Noto Sans is a fallback font; you can't specify it directly)

Note: this table is derived from fonts.xml. Each font's family name and style is listed in fonts.xml, e.g.

<family name="serif-monospace">
    <font weight="400" style="normal">CutiveMono.ttf</font>
</family>

serif-monospace is thus the font family, and normal is the style.

Compatibility

Based on the log of fonts.xml and the former system_fonts.xml, you can see when each font was added:

• Ice Cream Sandwich: Roboto regular, bold, italic, and bold italic
• Jelly Bean: Roboto light, light italic, condensed, condensed bold, condensed italic, and condensed bold italic
• Jelly Bean MR1: Roboto thin and thin italic
• Lollipop:
  • Roboto medium, medium italic, black, and black italic
  • Noto Serif regular, bold, italic, bold italic
  • Cutive Mono
  • Coming Soon
  • Dancing Script
  • Carrois Gothic SC
  • Noto Sans
• Oreo MR1: Roboto condensed medium

Since other solutions are old and either poorly-working or not working at all, I've modified NestedScrollView, which is stable, modern and it has all you expect from a scroll view. Except for horizontal scrolling.

Here's the repo: https://github.com/ultimate-deej/TwoWayNestedScrollView

I've made no changes, no "improvements" to the original NestedScrollView expect for what was absolutely necessary. The code is based on androidx.core:core:1.3.0, which is the latest stable version at the time of writing.

All of the following works:

• Lift on scroll (since it's basically a NestedScrollView)
• Edge effects in both dimensions
• Fill viewport in both dimensions

On OSX these commands worked for me

brew install mysql-connector-c 
pip install MySQL-python

int i,largest = 0;
Scanner scan = new Scanner(System.in);
System.out.println("Enter the number of numbers in the list");
i = scan.nextInt();
int arr[] = new int[i];
System.out.println("Enter the list of numbers:");
for(int j=0;j<i;j++){
    arr[j] = scan.nextInt();
}

The above code works well. I have taken the input of the number of elements in the list and initialized the array accordingly.

You can try FileUtils from org.apache.commons.io.FileUtils, try downloading jar from here

and you can use the following method: FileUtils.readFileToString("yourFileName");

Hope it helps you..

With postgres 9.3 use -> for object access. 4 example

seed.rb

se = SmartElement.new
se.data = 
{
    params:
    [
        {
            type: 1,
            code: 1,
            value: 2012,
            description: 'year of producction'
        },
        {
            type: 1,
            code: 2,
            value: 30,
            description: 'length'
        }
    ]
}

se.save

rails c

SELECT data->'params'->0 as data FROM smart_elements;

returns

                                 data
----------------------------------------------------------------------
 {"type":1,"code":1,"value":2012,"description":"year of producction"}
(1 row)

You can continue nesting

SELECT data->'params'->0->'type' as data FROM smart_elements;

return

 data
------
 1
(1 row)

Here’s the JavaScript equivalent:

var i = null;
var j = i || 10; //j is now 10

Note that the logical operator || does not return a boolean value but the first value that can be converted to true.

Additionally use an array of objects instead of one single object:

var options = {
    filters: [
        {
            name: 'firstName',
            value: 'abc'
        }
    ]
};
var filter  = options.filters[0] || '';  // is {name:'firstName', value:'abc'}
var filter2 = options.filters[1] || '';  // is ''

That can be accessed by index.

Why some of the answers on this page are wrong!

• Any answer that uses window.Focus() is wrong.

  • Why? If a notification message pops up, window.Focus() will grab the focus away from whatever the user is typing at the time. This is insanely frustrating for end users, especially if the popups occur quite frequently.

• Any answer that uses window.Activate() is wrong.

  • Why? It will make any parent windows visible as well.
• Any answer that omits window.ShowActivated = false is wrong.
  • Why? It will grab the focus away from another window when the message pops up which is very annoying!
• Any answer that does not use Visibility.Visible to hide/show the window is wrong.
  • Why? If we are using Citrix, if the window is not collapsed when it is closed, it will leave a weird black rectangular hold on the screen. Thus, we cannot use window.Show() and window.Hide().

Essentially:

• The window should not grab the focus away from any other window when it activates;
• The window should not activate its parent when it is shown;
• The window should be compatible with Citrix.

MVVM Solution

This code is 100% compatible with Citrix (no blank areas of the screen). It is tested with both normal WPF and DevExpress.

This answer is intended for any use case where we want a small notification window that is always in front of other windows (if the user selects this in the preferences).

If this answer seems more complex than the others, it's because it is robust, enterprise level code. Some of the other answers on this page are simple, but do not actually work.

XAML - Attached Property

Add this attached property to any UserControl within the window. The attached property will:

• Wait until the Loaded event is fired (otherwise it cannot look up the visual tree to find the parent window).
• Add an event handler that ensures that the window is visible or not.

At any point, you can set the window to be in front or not, by flipping the value of the attached property.

<UserControl x:Class="..."
         ...
         attachedProperties:EnsureWindowInForeground.EnsureWindowInForeground=
             "{Binding EnsureWindowInForeground, Mode=OneWay}">

            }

            window.Topmost = false;
        }
        catch (Exception)
        {
            // Gulp. Avoids "Cannot set visibility while window is closing".
        }
    }
}

Usage

In order to use this, you need to create the window in your ViewModel:

private ToastView _toastViewWindow;
private void ShowWindow()
{
    if (_toastViewWindow == null)
    {
        _toastViewWindow = new ToastView();
        _dialogService.Show<ToastView>(this, this, _toastViewWindow, true);
    }
    ShiftWindowOntoScreenHelper.ShiftWindowOntoScreen(_toastViewWindow);
    HideAndShowWindowHelper.ShiftWindowIntoForeground(_toastViewWindow);
}

private void HideWindow()
{
    if (_toastViewWindow != null)
    {
        HideAndShowWindowHelper.ShiftWindowIntoBackground(_toastViewWindow);
    }
}

I think the easiest way to match the characters like

\^$.?*|+()[

are using character classes from within R. Consider the following to clean column headers from a data file, which could contain spaces, and punctuation characters:

> library(stringr)
> colnames(order_table) <- str_replace_all(colnames(order_table),"[:punct:]|[:space:]","")

This approach allows us to string character classes to match punctation characters, in addition to whitespace characters, something you would normally have to escape with \\ to detect. You can learn more about the character classes at this cheatsheet below, and you can also type in ?regexp to see more info about this.

It can be better if you set the a element in this way

display:block;

and then by css sprites set your over background

Edit: check this example out http://jsfiddle.net/steweb/dTwtk/

std::string::iterator end_pos = std::remove(str.begin(), str.end(), ' ');
str.erase(end_pos, str.end());

function isNumberCandidate(s) {
  const str = (''+ s).trim();
  if (str.length === 0) return false;
  return !isNaN(+str);
}

console.log(isNumberCandidate('1'));       // true
console.log(isNumberCandidate('a'));       // false
console.log(isNumberCandidate('000'));     // true
console.log(isNumberCandidate('1a'));      // false 
console.log(isNumberCandidate('1e'));      // false
console.log(isNumberCandidate('1e-1'));    // true
console.log(isNumberCandidate('123.3'));   // true
console.log(isNumberCandidate(''));        // false
console.log(isNumberCandidate(' '));       // false
console.log(isNumberCandidate(1));         // true
console.log(isNumberCandidate(0));         // true
console.log(isNumberCandidate(NaN));       // false
console.log(isNumberCandidate(undefined)); // false
console.log(isNumberCandidate(null));      // false
console.log(isNumberCandidate(-1));        // true
console.log(isNumberCandidate('-1'));      // true
console.log(isNumberCandidate('-1.2'));    // true
console.log(isNumberCandidate(0.0000001)); // true
console.log(isNumberCandidate('0.0000001')); // true
console.log(isNumberCandidate(Infinity));    // true
console.log(isNumberCandidate(-Infinity));    // true

console.log(isNumberCandidate('Infinity'));  // true

if (isNumberCandidate(s)) {
  // use +s as a number
  +s ...
}

you can do it using the format function, here is a sample:

Format(mydate, "yyyy-MM-dd HH:mm:ss")

I haven't found this to work on, say Application objects. I have however had success with

var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();

string rval = serializer.Serialize(myAppObj);

EDIT: Per @sshow's comment, if you're trying to run your node app on port 80, the below is not the best way to do it. Here's a better answer: How do I run Node.js on port 80?

Original Answer:

If you want to do this to run on port 80 (or want to set the env variable more permanently),

1. Open up your bash profile vim ~/.bash_profile
2. Add the environment variable to the file export PORT=80
3. Open up the sudoers config file sudo visudo
4. Add the following line to the file exactly as so Defaults env_keep +="PORT"

Now when you run sudo node app.js it should work as desired.

That entire block is misplaced.

class Example(object):
    def main(self):     
        print "Hello World!"

if __name__ == '__main__':
    Example().main()

But you really shouldn't be using a class just to run your main code.

Unfortunately, you need to manually fire the change event. And using the Event Constructor will be the best solution.

var select = document.querySelector('#sel'),_x000D_
    input = document.querySelector('input[type="button"]');_x000D_
select.addEventListener('change',function(){_x000D_
    alert('changed');_x000D_
});_x000D_
input.addEventListener('click',function(){_x000D_
    select.value = 2;_x000D_
    select.dispatchEvent(new Event('change'));_x000D_
});

<select id="sel" onchange='alert("changed")'>_x000D_
  <option value='1'>One</option>_x000D_
  <option value='2'>Two</option>_x000D_
  <option value='3' selected>Three</option>_x000D_
</select>_x000D_
<input type="button" value="Change option to 2" />

And, of course, the Event constructor is not supported in IE. So you may need to polyfill with this:

function Event( event, params ) {
    params = params || { bubbles: false, cancelable: false, detail: undefined };
    var evt = document.createEvent( 'CustomEvent' );
    evt.initCustomEvent( event, params.bubbles, params.cancelable, params.detail );
    return evt;
}

This may help others where there is no option to Enable/Disable the history anywhere in Task Scheduler.

Open Event Viewer (either in Computer Management or Admin Tools > Event Viewer).

In Event Viewer make sure the Preview Pane is showing (View > Preview Pane should be ticked)

In the left hand pane expand Application and Service Logs then Microsoft, Windows, TaskScheduler and then select Operational.

You should have Actions showing in the preview pane with two sections - Operational and below that Event nnn, TaskScheduler. One of the items listed in the Operational section should be Properties. Click this item and the Enable Logging option is on the General tab.

My problem was that the maximum log size had been reached and even though the overwrite old events option was selected it wasn't logging new events. I suspect that might have been a permissions issue but I changed it to Archive when full and all is now working again.

Hope this helps someone else out there. If you don't have the options I've mentioned above I'm sorry, but I don't know where you should look.

I use the CONCATENATE method to take the values of a column and wrap quotes around them with columns in between in order to quickly populate the WHERE IN () clause of a SQL statement.

I always just type =CONCATENATE("'",B2,"'",",") and then select that and drag it down, which creates =CONCATENATE("'",B3,"'",","), =CONCATENATE("'",B4,"'",","), etc. then highlight that whole column, copy paste to a plain text editor and paste back if needed, thus stripping the row separation. It works, but again, just as a one time deal, this is not a good solution for someone who needs this all the time.

Another way:

Regex.Replace(urlString, "www.(.+)", "$1");

Yes you should change the name of your function. Javascript has reserved methods and onclick = >>>> click() <<<< is one of them so just rename it, add an 's' to the end of it or something. strong text`

The difference is that any composition is an aggregation and not vice versa.

Let's set the terms. The Aggregation is a metaterm in the UML standard, and means BOTH composition and shared aggregation, simply named shared. Too often it is named incorrectly "aggregation". It is BAD, for composition is an aggregation, too. As I understand, you mean "shared".

Further from UML standard:

composite - Indicates that the property is aggregated compositely, i.e., the composite object has responsibility for the existence and storage of the composed objects (parts).

So, University to cathedras association is a composition, because cathedra doesn't exist out of University (IMHO)

Precise semantics of shared aggregation varies by application area and modeler.

I.e., all other associations can be drawn as shared aggregations, if you are only following to some principles of yours or of somebody else. Also look here.

There is no such thing as one language being faster than another, so the proper answer is no.

What you really have to ask is "is code compiled with Fortran compiler X faster than equivalent code compiled with C compiler Y?" The answer to that question of course depends on which two compilers you pick.

Another question one could ask would be along the lines of "Given the same amount of effort put into optimizing in their compilers, which compiler would produce faster code?" The answer to this would in fact be Fortran. Fortran compilers have certian advantages:

• Fortran had to compete with Assembly back in the day when some vowed never to use compilers, so it was designed for speed. C was designed to be flexible.
• Fortran's niche has been number crunching. In this domain code is never fast enough. So there's always been a lot of pressure to keep the language efficient.
• Most of the research in compiler optimizations is done by people interested in speeding up Fortran number crunching code, so optimizing Fortran code is a much better known problem than optimizing any other compiled language, and new innovations show up in Fortran compilers first.
• Biggie: C encourages much more pointer use than Fortran. This drasticly increases the potential scope of any data item in a C program, which makes them far harder to optimize. Note that Ada is also way better than C in this realm, and is a much more modern OO Language than the commonly found Fortran77. If you want an OO langauge that can generate faster code than C, this is an option for you.
• Due again to its number-crunching niche, the customers of Fortran compilers tend to care more about optimization than the customers of C compilers.

However, there is nothing stopping someone from putting a ton of effort into their C compiler's optimization, and making it generate better code than their platform's Fortran compiler. In fact, the larger sales generated by C compilers makes this scenario quite feasible

I'm not sure you're what you mean: but here's a solution for a similar (and possibly the same) problem...

I often use preventDefault() to intercept items. However: it's not the only method of interception... often you may just want a "question" following which behaviour continues as before, or stops. In a recent case I used the following solution:

$("#content").on('click', '#replace', (function(event){ return confirm('Are you sure you want to do that?') }));

Basically, the "prevent default" is meant to intercept and do something else: the "confirm" is designed for use in ... well - confirming!

I thinks it is vary helpful way.

models.py

from django.db import models
class User(models.Model):
    user_name = models.CharField(max_length=100)
    password = models.CharField(max_length=32)

forms.py

from django import forms
from Admin.models import *
class User_forms(forms.ModelForm):
    class Meta:
        model= User
        fields=[
           'user_name',
           'password'
            ]
       widgets = {
      'password': forms.PasswordInput()
         }

Since I can only edit my own answer, I'm going to make a composite answer from the other answers to my question. Thanks to all of you who answered.

Using std::copy, this still iterates in the background, but you don't have to type out the code.

int foo(int* data, int size)
{
   static std::vector<int> my_data; //normally a class variable
   std::copy(data, data + size, std::back_inserter(my_data));
   return 0;
}

Using regular memcpy. This is probably best used for basic data types (i.e. int) but not for more complex arrays of structs or classes.

vector<int> x(size);
memcpy(&x[0], source, size*sizeof(int));

If you have GDAL/OGR compiled with the against the Expat library, you can use the XLSX driver to read .xlsx files, and run SQL expressions from a command prompt. For example, from a osgeo4w shell in the same directory as the spreadsheet, use the ogrinfo utility:

ogrinfo -dialect sqlite -sql "SELECT name, count(*) FROM sheet1 GROUP BY name" Book1.xlsx

will run a SQLite query on sheet1, and output the query result in an unusual form:

INFO: Open of `Book1.xlsx'
      using driver `XLSX' successful.

Layer name: SELECT
Geometry: None
Feature Count: 36
Layer SRS WKT:
(unknown)
name: String (0.0)
count(*): Integer (0.0)
OGRFeature(SELECT):0
  name (String) = Red
  count(*) (Integer) = 849

OGRFeature(SELECT):1
  name (String) = Green
  count(*) (Integer) = 265
...

Or run the same query using ogr2ogr to make a simple CSV file:

$ ogr2ogr -f CSV out.csv -dialect sqlite \
          -sql "SELECT name, count(*) FROM sheet1 GROUP BY name" Book1.xlsx

$ cat out.csv
name,count(*)
Red,849
Green,265
...

To do similar with older .xls files, you would need the XLS driver, built against the FreeXL library, which is not really common (e.g. not from OSGeo4w).

NOTE: if you do multiple inserts with one statement mysqli::insert_id will not be correct.

The table:

create table xyz (id int(11) auto_increment, name varchar(255), primary key(id));

Now if you do:

insert into xyz (name) values('one'),('two'),('three');

The mysqli::insert_id will be 1 not 3.

To get the correct value do:

mysqli::insert_id + mysqli::affected_rows) - 1

This has been document but it is a bit obscure.

System.Diagnostics.Process.Start( "notepad.exe", "text.txt");

If your array is not initialized then it contains randoms values and cannot be checked !

To initialize your array with 0 values:

int array[5] = {0};

Then you can check if the value is 0:

array[4] == 0;

When you compare to NULL, it compares to 0 as the NULL is defined as integer value 0 or 0L.

If you have an array of pointers, better use the nullptr value to check:

char* array[5] = {nullptr}; // we defined an array of char*, initialized to nullptr

if (array[4] == nullptr)
    // do something

In case you want to use a different logging framework, log4j for example, I found the easiest approach is to disable spring boots own logging and implement your own. That way I can configure every loglevel within one file, log4j.xml (in my case) that is.

To achieve this you simply have to add those lines to your pom.xml:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-log4j</artifactId>
</dependency>

You probably already have the first dependency and only need the other two. Please note, that this example only covers log4j.
That's all, now you're all set to configure logging for boot within your log4j config file!

Go to your Django project home directory and do:

./manage.py --version

you will need to button initilzation inside method instead of trying to initlzing View's at class level do it as:

 Button button;  //<< declare here..

   @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button= (Button) findViewById(R.id.standingsButton); //<< initialize here
         // set OnClickListener for Button here
        button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            startActivity(new Intent(MainActivity.this,StandingsActivity.class));
        }
      });
    }

For anyone trying to use jQuery.active with JSONP requests (like I was) you'll need enable it with this:

jQuery.ajaxPrefilter(function( options ) {
    options.global = true;
});

Keep in mind that you'll need a timeout on your JSONP request to catch failures.

$.browser was deprecated in version 1.3 and removed in 1.9

You can verify this by viewing the documentation.

This is what worked for me..

.table-no-border>thead>tr>th, 
.table-no-border>tbody>tr>th, 
.table-no-border>tfoot>tr>th, 
.table-no-border>thead>tr>td, 
.table-no-border>tbody>tr>td, 
.table-no-border>tfoot>tr>td,
.table-no-border>tbody,
.table-no-border>thead,
.table-no-border>tfoot{
  border-top: none !important; 
  border-bottom: none !important; 
}

Had to whip out the !important to make it stick.

You can try this issue using virtualenv

Here is test.py

#! /usr/bin/env python
import sys
print(sys.version)

Create virtual environments

virtualenv test2.6 -p /usr/bin/python2.6
virtualenv test2.7 -p /usr/bin/python2.7

activate each environment then check the differences

echo $PATH
./test.py

int[] a = {1,2,3,4,5};

int [] b= new int[a.length]; //New Array and the size of a which is 4

Array.Copy(a,b,a.length);

Where Array is class having method Copy, which copies the element of a array to b array.

While copying from one array to another array, you have to provide same data type to another array of which you are copying.

Mine got solved by enabling multiDex for debug builds.

If you are specifically looking for the 1-7 approach...

This is the ISO weekday number. moment.js has also taken this into account. Use isoWeekday()

console.log(moment().isoWeekday()); // returns 1-7 where 1 is Monday and 7 is Sunday

You should use 'zip' function. Here is an example how your own zip function can look like

def custom_zip(seq1, seq2):
    it1 = iter(seq1)
    it2 = iter(seq2)
    while True:
        yield next(it1), next(it2)

Found it, MSDTC on the remote server was a clone of the local server.

From the Windows Application Events Log:

Event Type: Error
Event Source: MSDTC
Event Category: CM
Event ID: 4101
Date: 9/19/2011
Time: 1:32:59 PM
User: N/A
Computer: ASITESTSERVER
Description:

The local MS DTC detected that the MS DTC on ASICMSTEST has the same unique identity as the local MS DTC. This means that the two MS DTC will not be able to communicate with each other. This problem typically occurs if one of the systems were cloned using unsupported cloning tools. MS DTC requires that the systems be cloned using supported cloning tools such as SYSPREP. Running 'msdtc -uninstall' and then 'msdtc -install' from the command prompt will fix the problem. Note: Running 'msdtc -uninstall' will result in the system losing all MS DTC configuration information.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

Running

msdtc -uninstall
msdtc -install

and then stopping and restarting SQL Server service fixed it.

When you call document.write after a page has loaded it will eliminate all content and replace it with the parameter you provide. Instead use DOM methods to add content, for example:

var OpenWindow = window.open('mypage.html','_blank','width=335,height=330,resizable=1');
var text = document.createTextNode('hi');
OpenWindow.document.body.appendChild(text);

If you want to use jQuery you get some better APIs to deal with. For example:

var OpenWindow = window.open('mypage.html','_blank','width=335,height=330,resizable=1');
$(OpenWindow.document.body).append('<p>hi</p>');

If you need the code to run after the new window's DOM is ready try:

var OpenWindow = window.open('mypage.html','_blank','width=335,height=330,resizable=1');
$(OpenWindow.document.body).ready(function() {
    $(OpenWindow.document.body).append('<p>hi</p>');
});

I had a similar issue, I started to write my application in Kotlin, after I rewrote one of my activities I wanted to see if there are any issues, the problem was that I was not sure how to send an intent from java file to kotlin file.

In this case I created a static function in kotlin (companion object), this function is getting a context (from the current activity) and returning the new intent while using the current context ("java" context) while using the kotlin class ("::class.java").

Here is my code:

 //this code will be in the kotlin activity - SearchActivity
 companion object {

    fun newIntent(context: Context): Intent {
        return Intent(context, SearchActivity::class.java)
    }
}

    //this is how you call SearchActivity from MainActivity.java
Intent searchIntent = SearchActivity.Companion.newIntent(this);
startActivity(searchIntent);

List<Object> object = new List<Object>();

You cannot do this because List is an interface and you cannot create object of any interface or in other word you cannot instantiate any interface. Moreover, you can assign any object of class which implements List to its reference variable. For example you can do this:

list<Object> object = new ArrayList<Object>();

Here ArrayList is a class which implements List, you can use any class which implements List.

I had the same issue:

raise SSLError(e)
requests.exceptions.SSLError: [Errno 8] _ssl.c:504: EOF occurred in violation of protocol

I had fiddler running, I stopped fiddler capture and did not see this error. Could be because of fiddler.

You could write an extension method (for what it's worth):

public static string EmptyNull(this string str)
{
    return str ?? "";
}

Now this works safely:

string str = null;
string upper = str.EmptyNull().ToUpper();

There are several Identity providers with SSO support out of the box, also third-party** products.

** The only problem with third party products is that they charge per user/month, and it can be quite expensive.

Some of the tools available and with APIs for .NET are:

• IdentityExpress (with Admin UI) by IdentityServer
• Centrify Identity Service
• Okta Identity (SAML 2.0)
• OneLogin

If you decide to go with your own implementation, you could use the frameworks below categorized by programming language.

• C#

  • IdentityServer3 (OAuth/OpenID protocols, OWIN/Katana)
  • IdentityServer4 (OAuth/OpenID protocols, ASP.NET Core)
  • OAuth 2.0 by Okta

• Javascript

  • passport-openidconnect (node.js)
  • oidc-provider (node.js)
  • openid-client (node.js)

• Python

  • pyoidc
  • Django OIDC Provider

I would go with IdentityServer4 and ASP.NET Core application, it's easy configurable and you can also add your own authentication provider. It uses OAuth/OpenID protocols which are newer than SAML 2.0 and WS-Federation.

I had problems closing the bootstrap modal dialog, if it was opened with:

$('#myModal').modal('show');

I solved this problem opening the dialog by the following link:

<a href="#myModal" data-toggle="modal">Open my dialog</a>

Do not forget the initialization:

$('#myModal').modal({show: false});

I also used the following attributes for the closing button:

data-dismiss="modal" data-target="#myModal"

I'm no expert with DOM or Javascript/Typescript but I think that the DOM-Tags can't handle real javascript object somehow. But putting the whole object in as a string and parsing it back to an Object/JSON worked for me:

interface TestObject {
  name:string;
  value:number;
}

@Component({
  selector: 'app',
  template: `
      <h4>Select Object via 2-way binding</h4>

      <select [ngModel]="selectedObject | json" (ngModelChange)="updateSelectedValue($event)">
        <option *ngFor="#o of objArray" [value]="o | json" >{{o.name}}</option>
      </select>

      <h4>You selected:</h4> {{selectedObject }}
  `,
  directives: [FORM_DIRECTIVES]
})
export class App {
  objArray:TestObject[];
  selectedObject:TestObject;
  constructor(){
    this.objArray = [{name: 'foo', value: 1}, {name: 'bar', value: 1}];
    this.selectedObject = this.objArray[1];
  }
  updateSelectedValue(event:string): void{
    this.selectedObject = JSON.parse(event);
  }
}

var array = $('#searchKeywords').val().split(",");

then

$.each(array,function(i){
   alert(array[i]);
});

OR

for (i=0;i<array.length;i++){
     alert(array[i]);
}

Things have become really easy with OWIN and WebAPI. In my search for a C# Proxy server, I also came across this post http://blog.kloud.com.au/2013/11/24/do-it-yourself-web-api-proxy/ . This will be the road I'm taking.

After running this:

react-native-rename "MyApp" -b com.mycompany.myapp

Make sure to also goto Build.gradle under android/app/... and rename the application Id as shown below:

defaultConfig {
        applicationId:com.appname.xxx
........
}

You can get the nodeValue of the first childNode using

$('.title')[0].childNodes[0].nodeValue

Even though you asked for wait() and notify() specifically, I feel that this quote is still important enough:

Josh Bloch, Effective Java 2nd Edition, Item 69: Prefer concurrency utilities to wait and notify (emphasis his):

Given the difficulty of using wait and notify correctly, you should use the higher-level concurrency utilities instead [...] using wait and notify directly is like programming in "concurrency assembly language", as compared to the higher-level language provided by java.util.concurrent. There is seldom, if ever, reason to use wait and notify in new code.

It is usually handled automatically.

If autodiscovery doesn't work. Edit the elastic search config file, by enabling unicast discovery

Node 1:

    cluster.name: mycluster
    node.name: "node1"
    node.master: true
    node.data: true
    discovery.zen.ping.multicast.enabled: false
    discovery.zen.ping.unicast.hosts: ["node1.example.com"]

Node 2:

    cluster.name: mycluster
    node.name: "node2"
    node.master: false
    node.data: true
    discovery.zen.ping.multicast.enabled: false
    discovery.zen.ping.unicast.hosts: ["node1.example.com"]

and so on for node 3,4,5. Make node 1 master, and the rest only as data nodes.

Edit: Please note that by ES rule, if you have N nodes, then by convention, N/2+1 nodes should be masters for fail-over mechanisms They may or may not be data nodes, though.

Also, in case auto-discovery doesn't work, most probable reason is because the network doesn't allow it (and therefore disabled). If too many auto-discovery pings take place across multiple servers, the resources to manage those pings will prevent other services from running correctly.

For ex, think of a 10,000 node cluster and all 10,000 nodes doing the auto-pings.

args is an array of pointers. So, here you are comparing args[i] (a pointer) to "&" (also a pointer). Well, the only way this will every be true is if somewhere you have args[i]="&" and even then, "&" is not guaranteed to point to the same place everywhere.

I believe what you are actually looking for is either strcmp to compare the entire string or your wanting to do if (*args[i] == '&') to compare the first character of the args[i] string to the & character

For me, I usually use DataContext together in order to bind two-depth property such as this question.

<TextBlock DataContext="{Binding SelectedRule}" Text="{Binding Name}" />

Or, I prefer to use ElementName because it achieves bindings only with view controls.

<TextBlock DataContext="{Binding ElementName=lbRules, Path=SelectedItem}" Text="{Binding Name}" />

You can do it like this (with a slightly modified array to show it works for non-square arrays):

        long[,] arr = new long[5, 4] { { 1, 2, 3, 4 }, { 1, 1, 1, 1 }, { 2, 2, 2, 2 }, { 3, 3, 3, 3 }, { 4, 4, 4, 4 } };

        int rowLength = arr.GetLength(0);
        int colLength = arr.GetLength(1);

        for (int i = 0; i < rowLength; i++)
        {
            for (int j = 0; j < colLength; j++)
            {
                Console.Write(string.Format("{0} ", arr[i, j]));
            }
            Console.Write(Environment.NewLine + Environment.NewLine);
        }
        Console.ReadLine();

You can read the csv file like this.

this makes use of splits and takes care of spaces.

ArrayList List = new ArrayList();
static ServerSocket Server;
static Socket socket;
static ArrayList<Object> list = new ArrayList<Object>();


public static void ReadFromXcel() throws FileNotFoundException
{   
    File f = new File("Book.csv");
    Scanner in = new Scanner(f);
    int count  =0;
    String[] date;
    String[] name;
    String[] Temp = new String[10];
    String[] Temp2 = new String[10];
    String[] numbers;
    ArrayList<String[]> List = new ArrayList<String[]>();
    HashMap m = new HashMap();

         in.nextLine();
         date = in.nextLine().split(",");
         name = in.nextLine().split(",");
         numbers = in.nextLine().split(",");
         while(in.hasNext())
         {
             String[] one = in.nextLine().split(",");
             List.add(one);
         }
         int xount = 0;
         //Making sure the lines don't start with a blank
         for(int y = 0; y<= date.length-1; y++)
         {
             if(!date[y].equals(""))
             {   
                 Temp[xount] = date[y];
                 Temp2[xount] = name[y];
                 xount++;
             }
         }

         date = Temp;
         name =Temp2;
         int counter = 0;
         while(counter < List.size())
         {
             String[] list = List.get(counter);
             String sNo = list[0];
             String Surname = list[1];
             String Name = list[2];
             for(int x = 3; x < list.length; x++)
             {           
                 m.put(numbers[x], list[x]);
             }
            Object newOne = new newOne(sNo, Name, Surname, m, false);
             StudentList.add(s);
             System.out.println(s.sNo);
             counter++;
         }

I just want to point out, you can use .selectedindex to make it a little cleaner

string value = gridview.Rows[gridview.SelectedIndex].Cells[1].Text.ToString();

The following computes floor(sqrt(N)) for N > 0:

x = 2^ceil(numbits(N)/2)
loop:
    y = floor((x + floor(N/x))/2)
    if y >= x
        return x
    x = y

This is a version of Newton's method given in Crandall & Pomerance, "Prime Numbers: A Computational Perspective". The reason you should use this version is that people who know what they're doing have proven that it converges exactly to the floor of the square root, and it's simple so the probability of making an implementation error is small. It's also fast (although it's possible to construct an even faster algorithm -- but doing that correctly is much more complex). A properly implemented binary search can be faster for very small N, but there you may as well use a lookup table.

To round to the nearest integer, just compute t = floor(sqrt(4N)) using the algorithm above. If the least significant bit of t is set, then choose x = (t+1)/2; otherwise choose t/2. Note that this rounds up on a tie; you could also round down (or round to even) by looking at whether the remainder is nonzero (i.e. whether t^2 == 4N).

Note that you don't need to use floating-point arithmetic. In fact, you shouldn't. This algorithm should be implemented entirely using integers (in particular, the floor() functions just indicate that regular integer division should be used).

Here is the official explanation: https://github.com/golang/go/wiki/InterfaceSlice

var dataSlice []int = foo()
var interfaceSlice []interface{} = make([]interface{}, len(dataSlice))
for i, d := range dataSlice {
    interfaceSlice[i] = d
}

something like

movie.setStopDate(movie.getStartDate() + movie.getDurationInMinutes()* 60000);

Use the following command:

git clone --depth <depth> -b <branch> <repo_url>

Where:

• depth is the amount of commits you want to include. i.e. if you just want the latest commit use git clone --depth 1
• branch is the name of the remote branch that you want to clone from. i.e. if you want the last 3 commits from master branch use git clone --depth 3 -b master
• repo_url is the url of your repository

Returns boolean value of a variable.

Instead, Boolean class can be used.

(please read code descriptions)

var X = "test"; // X value is "test" as a String value
var booleanX = !!X // booleanX is `true` as a Boolean value beacuse non-empty strings evaluates as `true` in boolean
var whatIsXValueInBoolean = Boolean(X) // whatIsXValueInBoolean is `true` again
console.log(Boolean(X) === !!X) // writes `true`

Namely, Boolean(X) = !!X in use.

Please check code snippet out below ?

let a = 0_x000D_
console.log("a: ", a) // writes a value in its kind_x000D_
console.log("!a: ", !a) // writes '0 is NOT true in boolean' value as boolean - So that's true.In boolean 0 means false and 1 means true._x000D_
console.log("!!a: ", !!a) // writes 0 value in boolean. 0 means false._x000D_
console.log("Boolean(a): ", Boolean(a)) // equals to `!!a`_x000D_
console.log("\n") // newline_x000D_
_x000D_
a = 1_x000D_
console.log("a: ", a)_x000D_
console.log("!a: ", !a)_x000D_
console.log("!!a: ", !!a) // writes 1 value in boolean_x000D_
console.log("\n") // newline_x000D_
_x000D_
a = ""_x000D_
console.log("a: ", a)_x000D_
console.log("!a: ", !a) // writes '"" is NOT true in boolean' value as boolean - So that's true.In boolean empty strings, null and undefined values mean false and if there is a string it means true._x000D_
console.log("!!a: ", !!a) // writes "" value in boolean_x000D_
console.log("\n") // newline_x000D_
_x000D_
a = "test"_x000D_
console.log("a: ", a) // writes a value in its kind_x000D_
console.log("!a: ", !a)_x000D_
console.log("!!a: ", !!a) // writes "test" value in boolean_x000D_
_x000D_
console.log("Boolean(a) === !!a: ", Boolean(a) === !!a) // writes true

all you are right! other way to getting !

payton109’s answer is correct if you’re in the default US-EAST-1 region. If your bucket is in a different region, use a slightly different URL:

https://s3-<region>.amazonaws.com/your.domain.com/some/asset

Where <region> is the bucket location name. For example, if your bucket is in the us-west-2 (Oregon) region, you can do this:

https://s3-us-west-2.amazonaws.com/your.domain.com/some/asset

file_get_contents() is not fetching the data from url,then i tried curl and it's working fine.

You can call .prop("tagName"). Examples:

jQuery("<a>").prop("tagName"); //==> "A"
jQuery("<h1>").prop("tagName"); //==> "H1"
jQuery("<coolTagName999>").prop("tagName"); //==> "COOLTAGNAME999"

If writing out .prop("tagName") is tedious, you can create a custom function like so:

jQuery.fn.tagName = function() {
  return this.prop("tagName");
};

Examples:

jQuery("<a>").tagName(); //==> "A"
jQuery("<h1>").tagName(); //==> "H1"
jQuery("<coolTagName999>").tagName(); //==> "COOLTAGNAME999"

Note that tag names are, by convention, returned CAPITALIZED. If you want the returned tag name to be all lowercase, you can edit the custom function like so:

jQuery.fn.tagNameLowerCase = function() {
  return this.prop("tagName").toLowerCase();
};

Examples:

jQuery("<a>").tagNameLowerCase(); //==> "a"
jQuery("<h1>").tagNameLowerCase(); //==> "h1"
jQuery("<coolTagName999>").tagNameLowerCase(); //==> "cooltagname999"

Super simple, does not count on spread operators or apply, if that's an issue.

b.map(x => a.push(x));

After running some performance tests on this, it's terribly slow, but answers the question in regards to not creating a new array. Concat is significantly faster, even jQuery's $.merge() whoops it.

https://jsperf.com/merge-arrays19b/1

This answer predates version 1.1.5 where a proper ternary in the $parse function wasn't available. Use this answer if you're on a lower version, or as an example of filters:

angular.module('myApp.filters', [])
  
  .filter('conditional', function() {
    return function(condition, ifTrue, ifFalse) {
      return condition ? ifTrue : ifFalse;
    };
  });

And then use it as

<i ng-class="checked | conditional:'icon-check':'icon-check-empty'"></i>

When your script is running, it blocks the page from doing anything. You can work around this with one of two ways:

• Use var foo = prompt("Give me input");, which will give you the string that the user enters into a popup box (or null if they cancel it)
• Split your code into two function - run one function to set up the user interface, then provide the second function as a callback that gets run when the user clicks the button.

If you are trying to check the type of an object after you parse a JSON string, I suggest checking the constructor attribute:

obj.constructor == Array || obj.constructor == String || obj.constructor == Object

This will be a much faster check than typeof or instanceof.

If a JSON library does not return objects constructed with these functions, I would be very suspiciouse of it.

Readability can be improved by static factory methods:

Compare

public class Foo{
  public Foo(boolean withBar){
    //...
  }
}

//...

// What exactly does this mean?
Foo foo = new Foo(true);
// You have to lookup the documentation to be sure.
// Even if you remember that the boolean has something to do with a Bar
// you might not remember whether it specified withBar or withoutBar.

to

public class Foo{
  public static Foo createWithBar(){
    //...
  }

  public static Foo createWithoutBar(){
    //...
  }
}

// ...

// This is much easier to read!
Foo foo = Foo.createWithBar();

int range = max - min + 1;
int num = rand() % range + min;

UPDATE: This is wrong answer, but it's still useful to understand why it's wrong. See comments.

How about unicode-escape?

>>> d = {1: "??? ????", 2: u"??? ????"}
>>> json_str = json.dumps(d).decode('unicode-escape').encode('utf8')
>>> print json_str
{"1": "??? ????", "2": "??? ????"}

For me setting alignItems to a parent did the trick, like:

var styles = StyleSheet.create({
  container: {
    alignItems: 'flex-end'
  }
});

For your question as asked

Columns(3).Insert
Range("c1:c4") = Application.Transpose(Array("Loc", "uk", "us", "nj"))

If you had a way of automatically looking up the data (ie matching uk against employer id) then you could do that in VBA

Use a wrapper

Any kind of wrapper is good.

With Java 8+, use either an AtomicInteger:

AtomicInteger ordinal = new AtomicInteger(0);
list.forEach(s -> {
  s.setOrdinal(ordinal.getAndIncrement());
});

... or an array:

int[] ordinal = { 0 };
list.forEach(s -> {
  s.setOrdinal(ordinal[0]++);
});

With Java 10+:

var wrapper = new Object(){ int ordinal = 0; };
list.forEach(s -> {
  s.setOrdinal(wrapper.ordinal++);
});

Note: be very careful if you use a parallel stream. You might not end up with the expected result. Other solutions like Stuart's might be more adapted for those cases.

For types other than int

Of course, this is still valid for types other than int. You only need to change the wrapping type to an AtomicReference or an array of that type. For instance, if you use a String, just do the following:

AtomicReference<String> value = new AtomicReference<>();
list.forEach(s -> {
  value.set("blah");
});

Use an array:

String[] value = { null };
list.forEach(s-> {
  value[0] = "blah";
});

Or with Java 10+:

var wrapper = new Object(){ String value; };
list.forEach(s->{
  wrapper.value = "blah";
});

Add nth Days, months and years

$n = 2;
for ($i = 0; $i <= $n; $i++){
    $d = strtotime("$i days");
    $x = strtotime("$i month");
    $y = strtotime("$i year");
    echo "Dates : ".$dates = date('d M Y', "+$d days");
    echo "<br>";
    echo "Months : ".$months = date('M Y', "+$x months");
    echo '<br>';
    echo "Years : ".$years = date('Y', "+$y years");
    echo '<br>';
}

Just use the == with the negation symbol (!). If dtfm is the name of your data.frame:

dtfm[!dtfm$C == "Foo", ]

Or, to move the negation in the comparison:

dtfm[dtfm$C != "Foo", ]

Or, even shorter using subset():

subset(dtfm, C!="Foo")

Using transform in combination with transition works flawlessly for me:

.ani-grow {
    -webkit-transition: all 0.5s ease; 
    -moz-transition: all 0.5s ease; 
    -o-transition: all 0.5s ease; 
    -ms-transition: all 0.5s ease; 
    transition: all 0.5s ease; 
}
.ani-grow:hover {
    transform: scale(1.01);
}

declare @locationType varchar(50);
declare @locationID int;

SELECT column1, column2
FROM viewWhatever
WHERE
@locationID = 
  CASE @locationType
      WHEN 'location' THEN account_location
      WHEN 'area' THEN xxx_location_area 
      WHEN 'division' THEN xxx_location_division 
  END

Use @Column annotation and define its length attribute. Check Hibernate's documentation for references (section 2.2.2.3).

It's not a direct answer to the question, however I would suggest in most cases to simply set multiple classes to each element:

<div class="myclass one"></div>
<div class="myclass two></div>
<div class="myclass three"></div>

In this way you can set rules for all myclass elements and then more specific rules for one, two and three.

.myclass { color: #f00; }

.two { font-weight: bold; }

etc.

I'm not really sure, I guess it depends on the task: how often to run, how much complicated and how much direct communication with the rails project is needed etc. I guess if there was just "One Best Way" to do something, there wouldn't be so many different ways to do it.

At my last job in a Rails project, we needed to make a batch invitation mailer (survey invitations, not spamming) which should send the planned mails whenever the server had time. I think we were going to use daemon tools to run the rake tasks I had created.

Unfortunately, our company had some money problems and was "bought" by the main rival so the project was never completed, so I don't know what we would eventually have used.

Please check my answer here. Basically I just had to :

@Override
protected void onSaveInstanceState(Bundle outState) {
    //No call for super(). Bug on API Level > 11.
}

Don't make the call to super() on the saveInstanceState method. This was messing things up...

This is a known bug in the support package.

If you need to save the instance and add something to your outState Bundle you can use the following:

@Override
protected void onSaveInstanceState(Bundle outState) {
    outState.putString("WORKAROUND_FOR_BUG_19917_KEY", "WORKAROUND_FOR_BUG_19917_VALUE");
    super.onSaveInstanceState(outState);
}

In the end the proper solution was (as seen in the comments) to use :

transaction.commitAllowingStateLoss();

when adding or performing the FragmentTransaction that was causing the Exception.

If I understand your question right:

To add a .net 2.0 Web Service Reference instead of a WCF Service Reference, right-click on your project and click 'Add Service Reference.'

Then click "Advanced.." at the bottom left of the dialog.

Then click "Add Web Reference.." on the bottom left of the next dialog.

Now you can add a regular SOAP web reference like you are looking for.

Without a bit more code ... its hard to say what's going on.

But if your code looks something like this:

<li routerLinkActive="active">
  <a [routerLink]="/categories"><p>Products Categories</p></a>
</li>
...
<router-outlet></router-outlet>
<myComponentA></myComponentA>
<myComponentB></myComponentB>

Then clicking on the router link will route to the categories route and display its template in the router outlet.

Hiding and showing the child components don't affect what is displayed in the router outlet.

So if you click the link again, the categories route is already displayed in the router outlet and it won't display/re-initialize again.

If you could be a bit more specific about what you are trying to do, we could provide more specific suggestions for you. :-)

Floating Point Exception happens because of an unexpected infinity or NaN. You can track that using gdb, which allows you to see what is going on inside your C program while it runs. For more details: https://www.cs.swarthmore.edu/~newhall/unixhelp/howto_gdb.php

In a nutshell, these commands might be useful...

gcc -g myprog.c

gdb a.out

gdb core a.out

ddd a.out

This ought to do the trick: just limit the result to 1 row; if a row comes back the $lectureName is Assigned, otherwise it's Available.

function checkLectureStatus($lectureName)
{
    $con = connectvar();
    mysql_select_db("mydatabase", $con);
    $result = mysql_query(
        "SELECT * FROM preditors_assigned WHERE lecture_name='$lectureName' LIMIT 1");

    if(mysql_fetch_array($result) !== false)
        return 'Assigned';
    return 'Available';
}

Here if you mention .getPath() then that will return the path of Jar and I guess you will need its parent to refer to all other config files placed with the jar. This code works on Windows. Add the code within the main class.

File jarDir = new File(MyAppName.class.getProtectionDomain().getCodeSource().getLocation().getPath());
String jarDirpath = jarDir.getParent();

System.out.println(jarDirpath);

If you want your numbers in ascending order you can add them into a set and then sort the set into an ascending list.

s = set()
if number1 not in s:
  s.add(number1)
if number2 not in s:
  s.add(number2)
...
s = sorted(s)  #Now a list in ascending order

Try this for a unique list.

ping -c 5 -b 10.10.0.255 | grep 'bytes from' | awk '{ print $4 }' | sort | uniq

another method (fetches live hosts):

fping -ag 192.168.1.0/24

Starting with Git version 2.5+ (Q2 2015), fetching a single commit (without cloning the full repo) is actually possible.

See commit 68ee628 by Fredrik Medley (moroten), 21 May 2015.
^{(Merged by Junio C Hamano -- gitster -- in commit a9d3493, 01 Jun 2015)}

You now have a new config (on the server side)

uploadpack.allowReachableSHA1InWant

Allow upload-pack to accept a fetch request that asks for an object that is reachable from any ref tip. However, note that calculating object reachability is computationally expensive.
Defaults to false.

If you combine that server-side configuration with a shallow clone (git fetch --depth=1), you can ask for a single commit (see t/t5516-fetch-push.sh:

git fetch --depth=1 ../testrepo/.git $SHA1

You can use the git cat-file command to see that the commit has been fetched:

git cat-file commit $SHA1

"git upload-pack" that serves "git fetch" can be told to serve commits that are not at the tip of any ref, as long as they are reachable from a ref, with uploadpack.allowReachableSHA1InWant configuration variable.

The full documentation is:

upload-pack: optionally allow fetching reachable sha1

With uploadpack.allowReachableSHA1InWant configuration option set on the server side, "git fetch" can make a request with a "want" line that names an object that has not been advertised (likely to have been obtained out of band or from a submodule pointer).
Only objects reachable from the branch tips, i.e. the union of advertised branches and branches hidden by transfer.hideRefs, will be processed.
Note that there is an associated cost of having to walk back the history to check the reachability.

This feature can be used when obtaining the content of a certain commit, for which the sha1 is known, without the need of cloning the whole repository, especially if a shallow fetch is used.

Useful cases are e.g.

• repositories containing large files in the history,
• fetching only the needed data for a submodule checkout,
• when sharing a sha1 without telling which exact branch it belongs to and in Gerrit, if you think in terms of commits instead of change numbers.
  (The Gerrit case has already been solved through allowTipSHA1InWant as every Gerrit change has a ref.)

Git 2.6 (Q3 2015) will improve that model.
See commit 2bc31d1, commit cc118a6 (28 Jul 2015) by Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit 824a0be, 19 Aug 2015)}

refs: support negative transfer.hideRefs

If you hide a hierarchy of refs using the transfer.hideRefs config, there is no way to later override that config to "unhide" it.
This patch implements a "negative" hide which causes matches to immediately be marked as unhidden, even if another match would hide it.
We take care to apply the matches in reverse-order from how they are fed to us by the config machinery, as that lets our usual "last one wins" config precedence work (and entries in .git/config, for example, will override /etc/gitconfig).

So you can now do:

git config --system transfer.hideRefs refs/secret
git config transfer.hideRefs '!refs/secret/not-so-secret'

to hide refs/secret in all repos, except for one public bit in one specific repo.

Git 2.7 (Nov/Dec 2015) will improve again:

See commit 948bfa2, commit 00b293e (05 Nov 2015), commit 78a766a, commit 92cab49, commit 92cab49, commit 92cab49 (03 Nov 2015), commit 00b293e, commit 00b293e (05 Nov 2015), and commit 92cab49, commit 92cab49, commit 92cab49, commit 92cab49 (03 Nov 2015) by Lukas Fleischer (lfos).

config.txt: document the semantics of hideRefs with namespaces

Right now, there is no clear definition of how transfer.hideRefs should behave when a namespace is set.
Explain that hideRefs prefixes match stripped names in that case. This is how hideRefs patterns are currently handled in receive-pack.

hideRefs: add support for matching full refs

In addition to matching stripped refs, one can now add hideRefs patterns that the full (unstripped) ref is matched against.
To distinguish between stripped and full matches, those new patterns must be prefixed with a circumflex (^).

Hence the new documentation:

transfer.hideRefs:

If a namespace is in use, the namespace prefix is stripped from each reference before it is matched against transfer.hiderefs patterns.
For example, if refs/heads/master is specified in transfer.hideRefs and the current namespace is foo, then refs/namespaces/foo/refs/heads/master is omitted from the advertisements but refs/heads/master and refs/namespaces/bar/refs/heads/master are still advertised as so-called "have" lines.
In order to match refs before stripping, add a ^ in front of the ref name. If you combine ! and ^, ! must be specified first.

R.. mentions in the comments the config uploadpack.allowAnySHA1InWant, which allows upload-pack to accept a fetch request that asks for any object at all. (Defaults to false).

See commit f8edeaa (Nov. 2016, Git v2.11.1) by David "novalis" Turner (novalis):

upload-pack: optionally allow fetching any sha1

It seems a little silly to do a reachabilty check in the case where we trust the user to access absolutely everything in the repository.

Also, it's racy in a distributed system -- perhaps one server advertises a ref, but another has since had a force-push to that ref, and perhaps the two HTTP requests end up directed to these different servers.

Here is the simple bug free solution (with source code), It is working for me.

1. Derive your ViewModel from INotifyPropertyChanged

2. Create a observable property CloseDialog in ViewModel

   public void Execute()
   {
       // Do your task here
   
       // if task successful, assign true to CloseDialog
       CloseDialog = true;
   }
   
   private bool _closeDialog;
   public bool CloseDialog
   {
       get { return _closeDialog; }
       set { _closeDialog = value; OnPropertyChanged(); }
   }
   
   public event PropertyChangedEventHandler PropertyChanged;
   
   private void OnPropertyChanged([CallerMemberName]string property = "")
   {
       if (PropertyChanged != null)
       {
           PropertyChanged(this, new PropertyChangedEventArgs(property));
       }
   }
   

   }

3. Attach a Handler in View for this property change

       _loginDialogViewModel = new LoginDialogViewModel();
       loginPanel.DataContext = _loginDialogViewModel;
       _loginDialogViewModel.PropertyChanged += OnPropertyChanged;
   

4. Now you are almost done. In the event handler make DialogResult = true

   protected void OnPropertyChanged(object sender, PropertyChangedEventArgs args)
   {
       if (args.PropertyName == "CloseDialog")
       {
           DialogResult = true;
       }
   }
   

In my case there was no log whatsoever.

My mistake was to push a view controller in a navigation stack that was already part of the navigation stack.

If you're having font size issues (your font isn't responding to size changes)...

@codester has the right code:

myButton.titleLabel!.font =  UIFont(name: YourfontName, size: 20)

However, my font size wasn't changing. It turns out that I asking for a font that didn't exist ("HelveticaNeue-Regular"). It wasn't causing a crash, but seemed to be just ignoring that font statement because of it. Once I changed the font to something that does exist, changes to "size: x" did render.

It is 2019 and many of the answers here would work, depending on what you want to do. If you want to pass in some internal state not visible in URL (params, query) you can use state since 7.2 (as I have learned just today :) ).

From the blog (credits Tomasz Kula) - you navigate to route....

...from ts: this.router.navigateByUrl('/details', { state: { hello: 'world' } });

...from HTML template: <a routerLink="/details" [state]="{ hello: 'world' }">Go</a>

And to pick it up in the target component:

constructor(public activatedRoute: ActivatedRoute) {}

  ngOnInit() {
    this.state$ = this.activatedRoute.paramMap
      .pipe(map(() => window.history.state))
  }

Late, but hope this helps someone with recent Angular.

By default, git will update execute file permissions if you change them. It will not change or track any other permissions.

If you don't see any changes when modifying execute permission, you probably have a configuration in git which ignore file mode.

Look into your project, in the .git folder for the config file and you should see something like this:

[core]
    filemode = false

You can either change it to true in your favorite text editor, or run:

git config core.filemode true

Then, you should be able to commit normally your files. It will only commit the permission changes.

you can add keyup event like this

template: `
  <input (keyup)="onKey($event)">
  <p>{{values}}</p>
`

in Component, code some like below

export class KeyUpComponent_v1 {
  values = '';

  onKey(event:any) { // without type info
    this.values += event.target.value + ' | ';
  }
}

I had a similar problem and the solution was to do this:

#cloud-container{
    position:absolute;
    top:0;
    bottom:0;
}

I wanted a page-centered div with height 100% of page height, so my total solution was:

#cloud-container{
    position:absolute;
    top:0;
    bottom:0;
    left:0;
    right:0; 
    width: XXXpx; /*otherwise div defaults to page width*/
    margin: 0 auto; /*horizontally centers div*/
}

You might need to make a parent element (or simply 'body') have position: relative;

Yes, this is possible. One of the main pros for using Swing is the ease with which the abstract controls can be created and manipulates.

Here is a quick and dirty way to extend the existing JButton class to draw a circle to the right of the text.

package test;

import java.awt.Color;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.Graphics;

import javax.swing.JButton;
import javax.swing.JFrame;

public class MyButton extends JButton {

    private static final long serialVersionUID = 1L;

    private Color circleColor = Color.BLACK;

    public MyButton(String label) {
        super(label);
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);

        Dimension originalSize = super.getPreferredSize();
        int gap = (int) (originalSize.height * 0.2);
        int x = originalSize.width + gap;
        int y = gap;
        int diameter = originalSize.height - (gap * 2);

        g.setColor(circleColor);
        g.fillOval(x, y, diameter, diameter);
    }

    @Override
    public Dimension getPreferredSize() {
        Dimension size = super.getPreferredSize();
        size.width += size.height;
        return size;
    }

    /*Test the button*/
    public static void main(String[] args) {
        MyButton button = new MyButton("Hello, World!");

        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(400, 400);

        Container contentPane = frame.getContentPane();
        contentPane.setLayout(new FlowLayout());
        contentPane.add(button);

        frame.setVisible(true);
    }

}

Note that by overriding paintComponent that the contents of the button can be changed, but that the border is painted by the paintBorder method. The getPreferredSize method also needs to be managed in order to dynamically support changes to the content. Care needs to be taken when measuring font metrics and image dimensions.

For creating a control that you can rely on, the above code is not the correct approach. Dimensions and colours are dynamic in Swing and are dependent on the look and feel being used. Even the default Metal look has changed across JRE versions. It would be better to implement AbstractButton and conform to the guidelines set out by the Swing API. A good starting point is to look at the javax.swing.LookAndFeel and javax.swing.UIManager classes.

http://docs.oracle.com/javase/8/docs/api/javax/swing/LookAndFeel.html

http://docs.oracle.com/javase/8/docs/api/javax/swing/UIManager.html

Understanding the anatomy of LookAndFeel is useful for writing controls: Creating a Custom Look and Feel

Just click the dropdown button on left side of RUN button (in your image the dropdown which is in red box) select 'app' option from that and RUN button will be enabled.

Please refer below screenshot.

i had same problem i fix this using if developing jsp, put mysql connetor into WEB-INF->lib folder after puting that in eclipse right click and go build-path -> configure build patha in library tab add external jar file give location where lib folder is

You can set a default style for the entire workbook (all worksheets):

$objPHPExcel->getDefaultStyle()
    ->getBorders()
    ->getTop()
        ->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getDefaultStyle()
    ->getBorders()
    ->getBottom()
        ->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getDefaultStyle()
    ->getBorders()
    ->getLeft()
        ->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getDefaultStyle()
    ->getBorders()
    ->getRight()
        ->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);

or

  $styleArray = array(
      'borders' => array(
          'allborders' => array(
              'style' => PHPExcel_Style_Border::BORDER_THIN
          )
      )
  );
$objPHPExcel->getDefaultStyle()->applyFromArray($styleArray);

And this can be used for all style properties, not just borders.

But column autosizing is structural rather than stylistic, and has to be set for each column on each worksheet individually.

EDIT

Note that default workbook style only applies to Excel5 Writer

if you want to change the only icon of radio button then you can only add android:button="@drawable/ic_launcher" to your radio button and for making sensitive on click then you have to use the selector

 <?xml version="1.0" encoding="utf-8"?>
 <selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:drawable="@drawable/image_what_you_want_on_select_state" android:state_checked="true"/>
<item android:drawable="@drawable/image_what_you_want_on_un_select_state"    android:state_checked="false"/>


 </selector>

and set to your radio android:background="@drawable/name_of_selector"

If you don't mind multiple inheritance (it is not that bad, after all), you may write simple class with private copy constructor and assignment operator and additionally subclass it:

class NonAssignable {
private:
    NonAssignable(NonAssignable const&);
    NonAssignable& operator=(NonAssignable const&);
public:
    NonAssignable() {}
};

class SymbolIndexer: public Indexer, public NonAssignable {
};

For GCC this gives the following error message:

test.h: In copy constructor ‘SymbolIndexer::SymbolIndexer(const SymbolIndexer&)’:
test.h: error: ‘NonAssignable::NonAssignable(const NonAssignable&)’ is private

I'm not very sure for this to work in every compiler, though. There is a related question, but with no answer yet.

UPD:

In C++11 you may also write NonAssignable class as follows:

class NonAssignable {
public:
    NonAssignable(NonAssignable const&) = delete;
    NonAssignable& operator=(NonAssignable const&) = delete;
    NonAssignable() {}
};

The delete keyword prevents members from being default-constructed, so they cannot be used further in a derived class's default-constructed members. Trying to assign gives the following error in GCC:

test.cpp: error: use of deleted function
          ‘SymbolIndexer& SymbolIndexer::operator=(const SymbolIndexer&)’
test.cpp: note: ‘SymbolIndexer& SymbolIndexer::operator=(const SymbolIndexer&)’
          is implicitly deleted because the default definition would
          be ill-formed:

UPD:

Boost already has a class just for the same purpose, I guess it's even implemented in similar way. The class is called boost::noncopyable and is meant to be used as in the following:

#include <boost/core/noncopyable.hpp>

class SymbolIndexer: public Indexer, private boost::noncopyable {
};

I'd recommend sticking to the Boost's solution if your project policy allows it. See also another boost::noncopyable-related question for more information.

var replaced = $("body").html().replace(/-1o9-2202/g,'The ALL new string');
$("body").html(replaced);

for variable:

var replaced = $("body").html().replace(new RegExp("-1o9-2202", "igm"),'The ALL new string');
$("body").html(replaced);

Even better, use DEFAULT instead of NULL. You want to store the default value, not a NULL that might trigger a default value.

But you'd better name all columns, with a piece of SQL you can create all the INSERT, UPDATE and DELETE's you need. Just check the information_schema and construct the queries you need. There is no need to do it all by hand, SQL can help you out.

Laravel 7

1. Create a migration file using cli command:

   php artisan make:migration add_paid_to_users_table --table=users

2. A file will be created in the migrations folder, open it in an editor.

3. Add to the function up():

Schema::table('users', function (Blueprint $table) {
    // Create new column
    // You probably want to make the new column nullable
    $table->integer('paid')->nullable()->after('status');
}

4. Add to the function down(), this will run in case migration fails for some reasons:

   $table->dropColumn('paid');

5. Run migration using cli command:

   php artisan migrate

In case you want to add a column to the table to create a foreign key constraint:

In step 3 of the above process, you'll use the following code:

$table->bigInteger('address_id')->unsigned()->nullable()->after('tel_number');

$table->foreign('address_id')->references('id')->on('addresses')->onDelete('SET NULL');

In step 4 of the above process, you'll use the following code:

// 1. Drop foreign key constraints
$table->dropForeign(['address_id']);
// 2. Drop the column
$table->dropColumn('address_id');

I had the same problem and here is how it worked for me :

1) Open XAMPP control panel.

2)On the right top corner go to config > Service and Port setting and change the port (I did 81 from 80).

3)Open config in Apache just right(next) to Apache admin Option and click on that and select first one (httpd.conf) it will open in the notepad.

4) There you find port listen 80 and replace it with 81 in all place and save the file.

5) Now restart Apache and MYSql

6) Now type following in Browser : http://localhost:81/phpmyadmin/

I hope this works.

In Spring, bean scope is used to decide which type of bean instance should be returned from Spring container back to the caller.

5 types of bean scopes are supported :

1. Singleton : It returns a single bean instance per Spring IoC container.This single instance is stored in a cache of such singleton beans, and all subsequent requests and references for that named bean return the cached object.If no bean scope is specified in bean configuration file, default to singleton.

2. Prototype : It returns a new bean instance each time when requested. It does not store any cache version like singleton.

3. Request : It returns a single bean instance per HTTP request.

   

4. Session : It returns a single bean instance per HTTP session (User level session).

5. GlobalSession : It returns a single bean instance per global HTTP session. It is only valid in the context of a web-aware Spring ApplicationContext (Application level session).

In most cases, you may only deal with the Spring’s core scope – singleton and prototype, and the default scope is singleton.

and.. we must call "waitTimer.purge()" for the GC. If you don't use Timer anymore, "purge()" !! "purge()" removes all canceled tasks from the task queue.

if(waitTimer != null) {
   waitTimer.cancel();
   waitTimer.purge();
   waitTimer = null;
}

A DataTable object represents tabular data as an in-memory, tabular cache of rows, columns, and constraints. The DataSet consists of a collection of DataTable objects that you can relate to each other with DataRelation objects.

One thing i would like to add In a signed int, which is the default value in mysql , 1 bit will be used to represent sign. -1 for negative and 0 for positive. So if your application insert only positive value it should better specify unsigned.

Try it using CONCAT

CONCAT('site.com/path/','%', CAST(t1.id AS CHAR(25)), '%','/more')

imp system/system-password@SID file=directory-you-selected\FILE.dmp log=log-dir\oracle_load.log fromuser=infodba touser=infodba commit=Y

From office 2010, we won't be able to use the common dialog box control, so it's nice to use the Application object to get the desired results.

Here I got a text box and Command button - paste the following code under the command button click event, which will open the file dialog box and add the File name to the Text box.

Dim sFileName  As String

sFileName = Application.GetOpenFilename("MS Excel (*.xlsx), *.xls")

TextBox1.Text = sFileName

You can build your HttpContent using the combination of JObject to avoid and JProperty and then call ToString() on it when building the StringContent:

        /*{
          "agent": {                             
            "name": "Agent Name",                
            "version": 1                                                          
          },
          "username": "Username",                                   
          "password": "User Password",
          "token": "xxxxxx"
        }*/

        JObject payLoad = new JObject(
            new JProperty("agent", 
                new JObject(
                    new JProperty("name", "Agent Name"),
                    new JProperty("version", 1)
                    ),
                new JProperty("username", "Username"),
                new JProperty("password", "User Password"),
                new JProperty("token", "xxxxxx")    
                )
            );

        using (HttpClient client = new HttpClient())
        {
            var httpContent = new StringContent(payLoad.ToString(), Encoding.UTF8, "application/json");

            using (HttpResponseMessage response = await client.PostAsync(requestUri, httpContent))
            {
                response.EnsureSuccessStatusCode();
                string responseBody = await response.Content.ReadAsStringAsync();
                return JObject.Parse(responseBody);
            }
        }

In controller you can use MvcHtmlString

public class HomeController : Controller
{
    public ActionResult Index()
    {
        string rawHtml = "<HTML></HTML>";
        ViewBag.EncodedHtml = MvcHtmlString.Create(rawHtml);
        return View();
    }
}

In your View you can simply use that dynamic property which you set in your Controller like below

<div>
        @ViewBag.EncodedHtml
</div>

To configure bash aliases, it's the same as if you were on a Unix platform: put them in a .bashrc in your home:

cd
echo alias ll=\'ls -l\' >> .bashrc

To have this change taken into account you should then either source this file (ie: run source .bashrc) or restart your terminal

(In some cases* you can find equivalent for .bashrc file in C:\Users\<username>\AppData\Local\GitHub\PortableGit_\etc\profile.d\aliases.sh. And you should add aliases in aliases.sh.)

(*this case is when you install Git for Windows GUI release from https://git-scm.com/download/win that contains GitBash)

This is a simpler version

import pandas as pd
df = pd.DataFrame(columns=('col1', 'col2', 'col3'))
for i in range(5):
   df.loc[i] = ['<some value for first>','<some value for second>','<some value for third>']`

If you want to increase the memory usage of the node globally - not only single script, you can export environment variable, like this:
export NODE_OPTIONS=--max_old_space_size=4096

Then you do not need to play with files when running builds like npm run build.

I faced this problem and when i started searching the important point i found is, the value u are looking up i.e M3 column should be present in the first column of the table u want to search https://support.office.com/en-us/article/VLOOKUP-function-0bbc8083-26fe-4963-8ab8-93a18ad188a1 check in lookup_value

Tried above for solutions to find cat ID of a post, but nothing worked, used the following instead:

$c_id = wp_get_post_categories($obj->ID);

Constructors are not normal methods and they cannot be "overridden". Saying that a constructor can be overridden would imply that a superclass constructor would be visible and could be called to create an instance of a subclass. This isn't true... a subclass doesn't have any constructors by default (except a no-arg constructor if the class it extends has one). It has to explicitly declare any other constructors, and those constructors belong to it and not to its superclass, even if they take the same parameters that the superclass constructors take.

The stuff you mention about default no arg constructors is just an aspect of how constructors work and has nothing to do with overriding.

I don't think it is necessary to "host" the content using the way from the accepted answer. It is too complicated for a normal user with limited developing skills.

Google actually has provided hosting feature without using Drive SDK/API, what you need is just few clicks. Check this out:

http://support.google.com/drive/bin/answer.py?hl=en&answer=2881970

It is the same to the answer of user1557669. However, in step 4, the URL is not correct, it is like:

https://drive.google.com/#folders/...

To get the correct host URL. Right click on the html file (you have to finish 1-3 steps first and put the html in the public shared folder), and select "Details" from the context menu. You will find the hosting URL right close to the bottom of the details panel. It should look like:

https://googledrive.com/host/.../abc.html

Then you can share the link to anyone. Happy sharing.

you try this code---

NSMutableArray *myMutableArray = [myArray mutableCopy];

and

NSArray *myArray = [myMutableArray copy];

Have you configured the jupyter_notebook_config.py file to allow external connections?

By default, Jupyter Notebook only accepts connections from localhost (eg, from the same computer that its running on). By modifying the NotebookApp.allow_origin option from the default ' ' to '*', you allow Jupyter to be accessed externally.

c.NotebookApp.allow_origin = '*' #allow all origins

You'll also need to change the IPs that the notebook will listen on:

c.NotebookApp.ip = '0.0.0.0' # listen on all IPs

Also see the details in a subsequent answer in this thread.

You can also use this free plug-and-play extension:

http://www.magentocommerce.com/magento-connect/manage-customer-account-menu.html

This extension does not touch any of the Magento core files.

With this extension you are able to:

1. Decide per menu item to show or hide it with one click in the Magento backend.
2. Rename menu items easily.

public class CustomEditText extends EditText {
    public CustomEditText(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomEditText(Context context) {
        super(context);
    }

    public CustomEditText(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }


    @Override
    protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {
        super.onFocusChanged(focused, direction, previouslyFocusedRect);
        this.setSelection(this.getText().length());
    }

    @Override
    protected void onSelectionChanged(int selStart, int selEnd) {

    }
}

User this CustomEditText in your XML file, this will work. I have tested this and it is working for me.

Why not just do a named export of the object:

let values = { a: 1, b: 2, c: 3 }
export { values }

or

export let values = { a: 1, b: 2, c: 3 }

and then a named import where you need it:

import { values } from './my-module'

let foo = values.a
let { a, b, c } = values

or

import { values as myModule } from './my-module'

let foo = myModule.a
let { a, b, c } = myModule

can do default export as well:

let values = { a: 1, b: 2, c: 3 }
export default values 

or

export default { a: 1, b: 2, c: 3 }

and then consume it:

import whateverIcallIt from './my-Module'

let foo = whateverIcallIt.a
let {a, b, c } = whateverIcallIt

If you want to export a bunch of individual values, say a bunch of constants, you can:

export const a = 1
export const b = 2
//...

or even

export const a = 1,
             b = 2,
             c = 3,
//...

and then import them individually:

import { a, b, c } from './my-module'

For others like me:

There was once an example in the SSL source in the directory demos/ssl/ with example code in C++. Now it's available only via the history: https://github.com/openssl/openssl/tree/691064c47fd6a7d11189df00a0d1b94d8051cbe0/demos/ssl

You probably will have to find a working version, I originally posted this answer at Nov 6 2015. And I had to edit the source -- not much.

  window.Tether = {};
</script>

in my html head tag to fool bootstrap's check. I then added a second require statement just before the require that loads my app, and subsequently, my bootstrap dependency:

require(['tether'], function (Tether) {
  window.Tether = Tether;
});

require([
  "app",
], function(App){
  App.initialize();
});

Using both of these in tandem and you should have no problem using current bootstrap 4 alpha build.

You can achieve this using a cursor but the performance is much slower than whileloop.. Here's the code:

set nocount on
declare cur cursor local fast_forward for
    (select filepath from Directory)
open cur;
declare @fullpath varchar(250);
declare @isExists int;

fetch from cur into @fullpath
while @@FETCH_STATUS = 0
    begin
        exec xp_fileexist @fullpath, @isExists out
        if @isExists = 1            
            print @fullpath + char(9) + char(9) + 'file exists'
        else            
            print @fullpath + char(9) + char(9) + 'file does not exists'
        fetch from cur into @fullpath
    end
close cur
deallocate cur

or you can put it in a tempTable if you want to integrate it in your frontend..

create proc GetFileStatus as
begin
    set nocount on
    create table #tempFileStatus(FilePath varchar(300),FileStatus varchar(30))
    declare cur cursor local fast_forward for
        (select filepath from Directory)
    open cur;
    declare @fullpath varchar(250);
    declare @isExists int;

    fetch from cur into @fullpath
    while @@FETCH_STATUS = 0
        begin
            exec xp_fileexist @fullpath, @isExists out
            if @isExists = 1                
                insert into #tempFileStatus values(@fullpath,'File exist')
            else
                insert into #tempFileStatus values(@fullpath,'File does not exists')
            fetch from cur into @fullpath
        end
    close cur
    deallocate cur
    select * from #tempFileStatus
    drop table #tempFileStatus
end

then call it using:

exec GetFileStatus

Not quite, the AND has to be lower-case.

<xsl:when test="4 &lt; 5 and 1 &lt; 2">
<!-- do something -->
</xsl:when>

I have used this way and Its a best forever. In this code null also handled

SELECT Title,
FirstName,
lastName, 
ISNULL(Title,'') + ' ' + ISNULL(FirstName,'') + ' ' + ISNULL(LastName,'') as FullName 
FROM Customer

Try this...

The part you should be interested in is the /? part, which should solve most other questions you have with the tool.

Yes, NSDictionary supports fast enumeration. With Objective-C 2.0, you can do this:

// To print out all key-value pairs in the NSDictionary myDict
for(id key in myDict)
    NSLog(@"key=%@ value=%@", key, [myDict objectForKey:key]);

The alternate method (which you have to use if you're targeting Mac OS X pre-10.5, but you can still use on 10.5 and iPhone) is to use an NSEnumerator:

NSEnumerator *enumerator = [myDict keyEnumerator];
id key;
// extra parens to suppress warning about using = instead of ==
while((key = [enumerator nextObject]))
    NSLog(@"key=%@ value=%@", key, [myDict objectForKey:key]);

Basically, Serializable is a marker interface that implies that a class is safe for serialization and the JVM determines how it is serialized. Externalizable contains 2 methods, readExternal and writeExternal. Externalizable allows the implementer to decide how an object is serialized, where as Serializable serializes objects the default way.

The difference between (R,) and (1,R) is literally the number of indices that you need to use. ones((1,R)) is a 2-D array that happens to have only one row. ones(R) is a vector. Generally if it doesn't make sense for the variable to have more than one row/column, you should be using a vector, not a matrix with a singleton dimension.

For your specific case, there are a couple of options:

1) Just make the second argument a vector. The following works fine:

    np.dot(M[:,0], np.ones(R))

2) If you want matlab like matrix operations, use the class matrix instead of ndarray. All matricies are forced into being 2-D arrays, and operator * does matrix multiplication instead of element-wise (so you don't need dot). In my experience, this is more trouble that it is worth, but it may be nice if you are used to matlab.

Instead of passing the ID, you can just pass the element itself:

<link onclick="doWithThisElement(this)" />

Or, if you insist on passing the ID:

<link id="foo" onclick="doWithThisElement(this.id)" />

Here's the JSFiddle Demo: http://jsfiddle.net/dRkuv/

For %appdata% take a look to

Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)

One way to do that is to set the cascade option on you "One" side of relationship:

class Employee {
   // 

   @OneToMany(cascade = {CascadeType.PERSIST})
   private Set<Vehicles> vehicles = new HashSet<Vehicles>();

   //
}

by this, when you call

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

it will save the vehicles too.

Knockout's documentation also mentions a much cleaner way of passing extra parameters to functions bound using an on-click binding using function.bind like this:

<button data-bind="click: myFunction.bind($data, 'param1', 'param2')">
    Click me
</button>

If-elseif-else can be written as a nested if-else. These are (logically speaking) equivalent:

if (A) 
{
    doA();
}
else if (B)
{
    doB();
}
else if (C)
{
    doC();
}
else
{
    doX();
}

is the same as:

if (A) 
{
    doA();
}
else
{
    if (B)
    {
        doB();
    }
    else
    {
         if (C)
         {
             doC();
         }
         else
         {
             doX();
         }
    }
}

The result is that ultimately only one of doA, doB, doC, or doX will be evaluated.

I have had this error for some time as well. It might be some kind of netbeans bug that has to do with netbeans connector. I can't find any mention of favicon.ico in my code or in the project settings.

I was able to fix it by putting the following line in the head section of my html file

<link rel="shortcut icon" href="#">

I am currently using this in my testing environment, but I would remove it for any production environment.

By calling it?

var path = System.Web.HttpContext.Current.Server.MapPath("default.aspx");

Make sure you add a reference to the System.Web assembly.

The answer by Nick Mitchinson is for Bootstrap version 2.

If you are using Bootstrap version 3, then forms have changed a bit. For bootstrap 3, use the following instead:

<div class="form-horizontal">
    <div class="form-group">
        <div class="col-md-6">
            <textarea class="form-control" rows="3" placeholder="What's up?" required></textarea>
        </div>
    </div>
</div>

Where, col-md-6 will target medium sized devices. You can add col-xs-6 etc to target smaller devices.

You are reading the wrong documentation. You want this: https://setuptools.readthedocs.io/en/latest/setuptools.html#develop-deploy-the-project-source-in-development-mode

1. Creating setup.py is covered in the distutils documentation in Python's standard library documentation here. The main difference (for python eggs) is you import setup from setuptools, not distutils.

2. Yep. That should be right.

3. I don't think so. pyc files can be version and platform dependent. You might be able to open the egg (they should just be zip files) and delete .py files leaving .pyc files, but it wouldn't be recommended.

4. I'm not sure. That might be “Development Mode”. Or are you looking for some “py2exe” or “py2app” mode?

To have multiple Xcode instances installed you can put them to different folders for example /Developer5.0.2/Xcode, but to use them in CI or build environment(command line) you need to setup some environment variables during the build. You can have more instructions here. So it is working not just with beta and fresh release, also it's working for the really old versions, you might need it to use with Marmalade or Unity plugins which is not support the latest Xcode versions yet(some times it's happens).

Strange nobody suggested the following nice trick I saw once on this very site :

template <class T>
struct has_foo
{
    struct S { void foo(...); };
    struct derived : S, T {};

    template <typename V, V> struct W {};

    template <typename X>
    char (&test(W<void (X::*)(), &X::foo> *))[1];

    template <typename>
    char (&test(...))[2];

    static const bool value = sizeof(test<derived>(0)) == 1;
};

You have to make sure T is a class. It seems that ambiguity in the lookup of foo is a substitution failure. I made it work on gcc, not sure if it is standard though.

You can use the NonNullable Utility Type:

Example

type T0 = NonNullable<string | number | undefined>;  // string | number
type T1 = NonNullable<string[] | null | undefined>;  // string[]

Docs.

I also enable the 'u' option on every bash script I write in order to do some extra checking:

set -u 

This will report the usage of uninitialized variables, like in the following script 'check_init.sh'

#!/bin/sh
set -u
message=hello
echo $mesage

Running the script :

$ check_init.sh

Will report the following :

./check_init.sh[4]: mesage: Parameter not set.

Very useful to catch typos

In Addition to Ben's Answer, You can try Below Queries as per your need

USE {database-name};  
GO  
-- Truncate the log by changing the database recovery model to SIMPLE.  
ALTER DATABASE {database-name}
SET RECOVERY SIMPLE;  
GO  
-- Shrink the truncated log file to 1 MB.  
DBCC SHRINKFILE ({database-file-name}, 1);  
GO  
-- Reset the database recovery model.  
ALTER DATABASE {database-name}
SET RECOVERY FULL;  
GO 

Update Credit @cema-sp

To find database file names use below query

select * from sys.database_files;

I have used the using Newtonsoft.Json as below. Create an object:

 public class WorklistSortColumn
  {
    [JsonProperty(PropertyName = "field")]
    public string Field { get; set; }

    [JsonProperty(PropertyName = "dir")]
    public string Direction { get; set; }

    [JsonIgnore]
    public string SortOrder { get; set; }
  }

Now Call the below method to serialize to Json object as shown below.

string sortColumn = JsonConvert.SerializeObject(worklistSortColumn);

I would use:

if (Stream.of("a","b","c").anyMatch("a"::equals)) {
    //Code to execute
};

or:

Stream.of("a","b","c")
    .filter("a"::equals)
    .findAny()
    .ifPresent(ignore -> /*Code to execute*/);

To check if variable is null or empty use this:

IF LEN(ISNULL(@var, '')) = 0
    -- Is empty or NULL
ELSE
    -- Is not empty and is not NULL

This works, apply in ul:

display:flex;
flex-direction:column;
flex-wrap:wrap;

The right way is this:

Integer i = Integer.class.cast(obj);

The method cast() is a much safer alternative to compile-time casting.

Can try to adopt approach from C++ Boost libraries. Something like this:

class HashUtil
{
  public static int HashCombine(int seed, int other)
  {
    unchecked
    {
      return other + 0x9e3779b9 + (seed << 6) + (seed >> 2);
    }
  }
}

and then:

class MyClass
{
  private string _field1;
  private int _field2;
  private AnotherClass _field3;
  private YetAnotherClass _field4;

  public override int GetHashCode()
  {
    int result = HashUtil.HashCombine(_field1.GetHashCode(), _field2);
    result = HashUtil.HashCombine(result, _field3.GetHashCode());
    return HashUtil.HashCombine(result, _field4.GetHashCode());
  }
}

You need to use gdb's memory-display commands. The basic one is x, for examine. There's an example on the linked-to page that uses

gdb> x/4xw $sp

to print "four words (w ) of memory above the stack pointer (here, $sp) in hexadecimal (x)". The quotation is slightly paraphrased.

Some posters have already mentioned pipes and kqueue. In fact you can also create a pair of connected Unix domain sockets by the socketpair() call. The socket type should be SOCK_STREAM.

Let us suppose you have the two socket file descriptors fd1, fd2. Now fork() to create the child process, which will inherit the fds. In the parent you close fd2 and in the child you close fd1. Now each process can poll() the remaining open fd on its own end for the POLLIN event. As long as each side doesn't explicitly close() its fd during normal lifetime, you can be fairly sure that a POLLHUP flag should indicate the other's termination (no matter clean or not). Upon notified of this event, the child can decide what to do (e.g. to die).

#include <unistd.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <poll.h>
#include <stdio.h>

int main(int argc, char ** argv)
{
    int sv[2];        /* sv[0] for parent, sv[1] for child */
    socketpair(AF_UNIX, SOCK_STREAM, 0, sv);

    pid_t pid = fork();

    if ( pid > 0 ) {  /* parent */
        close(sv[1]);
        fprintf(stderr, "parent: pid = %d\n", getpid());
        sleep(100);
        exit(0);

    } else {          /* child */
        close(sv[0]);
        fprintf(stderr, "child: pid = %d\n", getpid());

        struct pollfd mon;
        mon.fd = sv[1];
        mon.events = POLLIN;

        poll(&mon, 1, -1);
        if ( mon.revents & POLLHUP )
            fprintf(stderr, "child: parent hung up\n");
        exit(0);
    }
}

You can try compiling the above proof-of-concept code, and run it in a terminal like ./a.out &. You have roughly 100 seconds to experiment with killing the parent PID by various signals, or it will simply exit. In either case, you should see the message "child: parent hung up".

Compared with the method using SIGPIPE handler, this method doesn't require trying the write() call.

This method is also symmetric, i.e. the processes can use the same channel to monitor each other's existence.

This solution calls only the POSIX functions. I tried this in Linux and FreeBSD. I think it should work on other Unixes but I haven't really tested.

See also:

• unix(7) of Linux man pages, unix(4) for FreeBSD, poll(2), socketpair(2), socket(7) on Linux.

In my case using app:autoSize was not solving all cases, for example it doesn't prevent word breaking

This is what I ended up using, it will resize down the text so that there are no word breaks on multiple lines

/**
 * Resizes down the text size so that there are no word breaks
 */
class AutoFitTextView @JvmOverloads constructor(
    context: Context,
    attrs: AttributeSet? = null,
    defStyleAttr: Int = 0
) : AppCompatTextView(context, attrs, defStyleAttr) {

    private val paint = Paint()
    private val bounds = Rect()

    override fun onMeasure(widthMeasureSpec: Int, heightMeasureSpec: Int) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec)
        var shouldResize = false
        paint.typeface = typeface
        var textSize = textSize
        paint.textSize = textSize
        val biggestWord: String = text.split(" ").maxByOrNull { it.count() } ?: return

        // Set bounds equal to the biggest word bounds
        paint.getTextBounds(biggestWord, 0, biggestWord.length, bounds)

        // Iterate to reduce the text size so that it makes the biggest word fit the line
        while ((bounds.width() + paddingStart + paddingEnd + paint.fontSpacing) > measuredWidth) {
            textSize--
            paint.textSize = textSize
            paint.getTextBounds(biggestWord, 0, biggestWord.length, bounds)
            shouldResize = true
        }
        if (shouldResize) {
            setTextSize(TypedValue.COMPLEX_UNIT_PX, textSize)
        }
    }
}

Sometimes yes they are related, and sometimes no they are not related, actually we sometimes use more space to get faster algorithms as in dynamic programming https://www.codechef.com/wiki/tutorial-dynamic-programming dynamic programming uses memoization or bottom-up, the first technique use the memory to remember the repeated solutions so the algorithm needs not to recompute it rather just get them from a list of solutions. and the bottom-up approach start with the small solutions and build upon to reach the final solution. Here two simple examples, one shows relation between time and space, and the other show no relation: suppose we want to find the summation of all integers from 1 to a given n integer: code1:

sum=0
for i=1 to n
   sum=sum+1
print sum

This code used only 6 bytes from memory i=>2,n=>2 and sum=>2 bytes therefore time complexity is O(n), while space complexity is O(1) code2:

array a[n]
a[1]=1
for i=2 to n
    a[i]=a[i-1]+i
print a[n]

This code used at least n*2 bytes from the memory for the array therefore space complexity is O(n) and time complexity is also O(n)

This works in webpack 3:

in the webpack.config.babel.js file:

resolve: {
    alias: {
         jquery: "jquery/src/jquery"
    },
 ....
}

And use ProvidePlugin

new webpack.ProvidePlugin({
        '$': 'jquery',
        'jQuery': 'jquery',
    })

I can't comment yet, but make sure you made all the checks in this quide: How to enable remote connections in SQL Server 2008? It should work fine if all steps are made.

Following example for getting first character from a string might help someone

string anyNameForString = "" + stringVariableName[0];

You should use querySelectorAll. It returns NodeList, however querySelector returns only the first found element:

var deleteLink = document.querySelectorAll('.delete');

Then you would loop:

for (var i = 0; i < deleteLink.length; i++) {
    deleteLink[i].addEventListener('click', function(event) {
        if (!confirm("sure u want to delete " + this.title)) {
            event.preventDefault();
        }
    });
}

Also you should preventDefault only if confirm === false.

It's also worth noting that return false/true is only useful for event handlers bound with onclick = function() {...}. For addEventListening you should use event.preventDefault().

Demo: http://jsfiddle.net/Rc7jL/3/

ES6 version

You can make it a little cleaner (and safer closure-in-loop wise) by using Array.prototype.forEach iteration instead of for-loop:

var deleteLinks = document.querySelectorAll('.delete');

Array.from(deleteLinks).forEach(link => {
    link.addEventListener('click', function(event) {
        if (!confirm(`sure u want to delete ${this.title}`)) {
            event.preventDefault();
        }
    });
});

_{Example above uses Array.from and template strings from ES2015 standard.}
