For getting the practical view of converting .apk file into .java files just check out https://www.youtube.com/watch?v=-AX4NYE-9V8 video . you will get more benefited and understand clearly. It clearly demonstrates the steps you required if you are using mac OS.

The basic requirement for getting this done. 1. http://code.google.com/p/dex2jar/
2. http://jd.benow.ca/

Since the column may be null in the database, the rs.getString() will throw a NullPointerException()

No.

rs.getString will not throw NullPointer if the column is present in the selected result set (SELECT query columns) For a particular record if value for the 'comumn is null in db, you must do something like this -

String myValue = rs.getString("myColumn");
if (rs.wasNull()) {
    myValue = ""; // set it to empty string as you desire.
}

You may want to refer to wasNull() documentation -

From java.sql.ResultSet
boolean wasNull() throws SQLException;

* Reports whether
* the last column read had a value of SQL <code>NULL</code>.
* Note that you must first call one of the getter methods
* on a column to try to read its value and then call
* the method <code>wasNull</code> to see if the value read was
* SQL <code>NULL</code>.
*
* @return <code>true</code> if the last column value read was SQL
*         <code>NULL</code> and <code>false</code> otherwise
* @exception SQLException if a database access error occurs or this method is 
*            called on a closed result set
*/

i++: In this scenario first the value is assigned and then increment happens.

++i: In this scenario first the increment is done and then value is assigned

Below is the image visualization and also here is a nice practical video which demonstrates the same.

An abstract class can be used instead of an interface (in C# 7.3).

// Like interface
abstract class IIO
{
    public virtual async Task<string> DoOperation(string Name)
    {
        throw new NotImplementedException(); // throwing exception
        // return await Task.Run(() => { return ""; }); // or empty do
    }
}

// Implementation
class IOImplementation : IIO
{
    public override async Task<string> DoOperation(string Name)
    {
        return await await Task.Run(() =>
        {
            if(Name == "Spiderman")
                return "ok";
            return "cancel";
        }); 
    }
}

The answer is .IsPostBack as suggested by @Kundan Singh Chouhan. Just to add to it, move your code into a separate method from Page_Load

private void PopulateFields()
{
  using(SqlConnection con1 = new SqlConnection("Data Source=USER-PC;Initial Catalog=webservice_database;Integrated Security=True"))
  {
    DataTable dt = new DataTable();
    con1.Open();
    SqlDataReader myReader = null;  
    SqlCommand myCommand = new SqlCommand("select * from customer_registration where username='" + Session["username"] + "'", con1);

    myReader = myCommand.ExecuteReader();

    while (myReader.Read())
    {
        TextBoxPassword.Text = (myReader["password"].ToString());
        TextBoxRPassword.Text = (myReader["retypepassword"].ToString());
        DropDownListGender.SelectedItem.Text = (myReader["gender"].ToString());
        DropDownListMonth.Text = (myReader["birth"].ToString());
        DropDownListYear.Text = (myReader["birth"].ToString());
        TextBoxAddress.Text = (myReader["address"].ToString());
        TextBoxCity.Text = (myReader["city"].ToString());
        DropDownListCountry.SelectedItem.Text = (myReader["country"].ToString());
        TextBoxPostcode.Text = (myReader["postcode"].ToString());
        TextBoxEmail.Text = (myReader["email"].ToString());
        TextBoxCarno.Text = (myReader["carno"].ToString());
    }
    con1.Close();
  }//end using
}

Then call it in your Page_Load

protected void Page_Load(object sender, EventArgs e)
{

    if(!Page.IsPostBack)
    {
       PopulateFields();
    }
}

check boxlist selected values with seperator

 string items = string.Empty;
        foreach (ListItem i in CheckBoxList1.Items)
        {
            if (i.Selected == true)
            {
                items += i.Text + ",";
            }
        }
        Response.Write("selected items"+ items);

Scanner has a method called hasNext():

    Scanner scanner = new Scanner(System.in);

    while(scanner.hasNext())
    {
        System.out.println(scanner.nextInt());
    }

You can get the index of the current iteration by adding another parameter to your iterator function, e.g.

_.each(['foo', 'bar', 'baz'], function (val, i) {
    console.log(i + ": " + val); // 0: foo, 1: bar, 2: baz
});

Rather than doing string manipulation, you can use the HOUR, MINUTE, SECOND functions to break apart the time. You can then multiply by 60*60*1000, 60*1000, and 1000 respectively to get milliseconds.

You can get the file name, but you can also get the full path, depending what you place between the '%~' and the '0'. Take your pick from

d -- drive
p -- path
n -- file name
x -- extension
f -- full path

E.g., from inside c:\tmp\foo.bat, %~nx0 gives you "foo.bat", whilst %~dpnx0 gives "c:\tmp\foo.bat". Note the pieces are always assembled in canonical order, so if you get cute and try %~xnpd0, you still get "c:\tmp\foo.bat"

Using numpy.savetxt is also an option:

import numpy as np

np.savetxt('list.txt', list, delimiter="\n", fmt="%s")

It is working for me.

Get in Timestamp type:

public static Timestamp getCurrentTimestamp() {
    TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
    final Calendar cal = Calendar.getInstance();
    Date date = cal.getTime();
    Timestamp ts = new Timestamp(date.getTime());
    return ts;
}

Get in String type:

    public static String getCurrentTimestamp() {
    TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
    final Calendar cal = Calendar.getInstance();
    Date date = cal.getTime();
    Timestamp ts = new Timestamp(date.getTime());
    return ts.toString();
}

An alternative method is use the setMinimumFractionDigits method from the NumberFormat class.

Here you basically specify how many numbers you want to appear after the decimal point.

So an input of 4.0 would produce 4.00, assuming your specified amount was 2.

But, if your Double input contains more than the amount specified, it will take the minimum amount specified, then add one more digit rounded up/down

For example, 4.15465454 with a minimum amount of 2 specified will produce 4.155

NumberFormat nf = NumberFormat.getInstance();
nf.setMinimumFractionDigits(2);
Double myVal = 4.15465454;
System.out.println(nf.format(myVal));

Usually, this problem resolve with using the modulo of a number in a loop or convert a number to a string. For convert a number to a string, you may can use the function itoa, so considering the variant with the modulo of a number in a loop.

Code to simply get the contents as text instead of html:

'html_text' parameter is the string which you will pass in this function to get the text

from bs4 import BeautifulSoup

soup = BeautifulSoup(html_text, 'lxml')
text = soup.get_text()
print(text)

Usually, if you are using bootstrap you can do this to set a min-height of 100%.

 <div class="container-fluid min-vh-100"></div>

this will also solve the footer not sticking at the bottom.

you can also do this from CSS with the following class

.stickDamnFooter{min-height: 100vh;}

if this class does not stick your footer just add position: fixed; to that same css class and you will not have this issue in a lifetime. Cheers.

Using a more geometric approach, calculate the following distances:

ab = sqrt((a.x-b.x)**2 + (a.y-b.y)**2)
ac = sqrt((a.x-c.x)**2 + (a.y-c.y)**2)
bc = sqrt((b.x-c.x)**2 + (b.y-c.y)**2)

and test whether ac+bc equals ab:

is_on_segment = abs(ac + bc - ab) < EPSILON

That's because there are three possibilities:

• The 3 points form a triangle => ac+bc > ab
• They are collinear and c is outside the ab segment => ac+bc > ab
• They are collinear and c is inside the ab segment => ac+bc = ab

i had the same problem... every time that i wanted to publish my css.. I had to make a search/replace.. and relative path wouldnt work either for me because the relative paths were different from dev to production.

Finally was tired of doing the search/replace and I created a dynamic css, (e.g. www.mysite.com/css.php) it's the same but now i could use my php constants in the css. somethig like

.icon{
  background-image:url('<?php echo BASE_IMAGE;?>icon.png');
}

and it's not a bad idea to make it dynamic because now i could compress it using YUI compressor without loosing the original format on my dev server.

Good Luck!

Ran into this error bc cell re-use identifier was wrong-- a rookie mistake but it happens: 1. Makes SURE cell re-use idenifier has no misspellings or missing letters. 2. Along same line, don't forget capitalization counts. 3. Zeroes are not "O"s (Ohs)

In VS2013 I did this in the following steps:

1.Right-click the web application project and hit Properties

2.View the "Web" tab of the Properties page

3.Under Servers, with "IIS Express" being the default choice of the dropdown, in the "Project Url" change the url using the port number to one that suits you. For example I deleted the port number and added "/MVCDemo4" after the localhost.

4.Click the "Create Virtual Directory" button.

5.Run your project and the new url will be used

Many people prefer to use just .keep since the convention has nothing to do with git.

This may help shed a little light: (from page 11 of PDF32000.book)

PDF syntax is best understood by considering it as four parts, as shown in Figure 1:

• Objects. A PDF document is a data structure composed from a small set of basic types of data objects. Sub-clause 7.2, "Lexical Conventions," describes the character set used to write objects and other syntactic elements. Sub-clause 7.3, "Objects," describes the syntax and essential properties of the objects. Sub-clause 7.3.8, "Stream Objects," provides complete details of the most complex data type, the stream object.

• File structure. The PDF file structure determines how objects are stored in a PDF file, how they are accessed, and how they are updated. This structure is independent of the semantics of the objects. Sub- clause 7.5, "File Structure," describes the file structure. Sub-clause 7.6, "Encryption," describes a file-level mechanism for protecting a document’s contents from unauthorized access.

• Document structure. The PDF document structure specifies how the basic object types are used to represent components of a PDF document: pages, fonts, annotations, and so forth. Sub-clause 7.7, "Document Structure," describes the overall document structure; later clauses address the detailed semantics of the components.

• Content streams. A PDF content stream contains a sequence of instructions describing the appearance of a page or other graphical entity. These instructions, while also represented as objects, are conceptually distinct from the objects that represent the document structure and are described separately. Sub-clause 7.8, "Content Streams and Resources," discusses PDF content streams and their associated resources.

Looks like navigating a PDF file will require a little more than a passing effort.

An alternative to other layouts, might be to put your panel with the GridLayout, inside another panel that is a FlowLayout. That way your spacing will be intact but will not expand across the entire available space.

It is basically a two-step process:

1. install cmap

pip install cmap

2. install dlib

pip install https://pypi.python.org/packages/da/06/bd3e241c4eb0a662914b3b4875fc52dd176a9db0d4a2c915ac2ad8800e9e/dlib-19.7.0-cp36-cp36m-win_amd64.whl#md5=b7330a5b2d46420343fbed5df69e6a3f

If you are looking for a hard limit across all uploads on the site, you can limit these in php.ini by setting the following:

`upload_max_filesize = 2M` `post_max_size = 2M`

that will set the maximum upload limit to 2 MB

I had this problem using Eclipse and solved it as follows:

In the pylint folder (e.g. C:\Python26\Lib\site-packages\pylint), hold Shift, right-click and choose to open the windows command in that folder. Type:

lint.py --generate-rcfile > standard.rc

This creates the standard.rc configuration file. Open it in Notepad and under [MESSAGES CONTROL], uncomment disable= and add the message ID's you want to disable, e.g.:

disable=W0511, C0321

Save the file, and in Eclipse ? Window ? Preferences ? PyDev ? *pylint, in the arguments box, type:

--rcfile=C:\Python26\Lib\site-packages\pylint\standard.rc

Now it should work...

You can also add a comment at the top of your code that will be interpreted by Pylint:

# pylint: disable=C0321

Pylint message codes.

Adding e.g. --disable-ids=C0321 in the arguments box does not work.

All available Pylint messages are stored in the dictionary _messages, an attribute of an instance of the pylint.utils.MessagesHandlerMixIn class. When running Pylint with the argument --disable-ids=... (at least without a configuration file), this dictionary is initially empty, raising a KeyError exception within Pylint (pylint.utils.MessagesHandlerMixIn.check_message_id().

In Eclipse, you can see this error-message in the Pylint Console (windows* ? show view ? Console, select Pylint console from the console options besides the console icon.)

You will want to check out the jQuery animate() feature. The standard way of doing this is positioning an element absolutely and then animating the "left" or "right" CSS property. An equally popular way is to increase/decrease the left or right margin.

Now, having said this, you need to be aware of severe performance loss for any type of animation that lasts longer than a second or two. Javascript was simply not meant to handle long, sustained, slow animations. This has to do with the way the DOM element is redrawn and recalculated for each "frame" of the animation. If you're doing a page-width animation that lasts more than a couple seconds, expect to see your processor spike by 50% or more. If you're on IE6, prepare to see your computer spontaneously combust into a flaming ball of browser incompetence.

To read up on this, check out this thread (from my very first Stackoverflow post no less)!

Here's a link to the jQuery docs for the animate() feature: http://docs.jquery.com/Effects/animate

Note that the onload event doesn't seem to fire if the iframe is loaded when offscreen. This frequently occurs when using "Open in New Window" /w tabs.

To just get the list of the changed files with the paths, use

svn diff --summarize -r<rev-of-commit>:<rev-of-commit - 1>

For example:

svn diff --summarize -r42:41

should result in something like

M       path/to/modifiedfile
A       path/to/newfile

2017 version

You can use

targetElement.insertAdjacentElement('afterbegin', newFirstElement)

From MDN :

The insertAdjacentElement() method inserts a given element node at a given position relative to the element it is invoked upon.

position
A DOMString representing the position relative to the element; must be one of the following strings:
beforebegin: Before the element itself.
afterbegin: Just inside the element, before its first child.
beforeend: Just inside the element, after its last child.
afterend: After the element itself.

element
The element to be inserted into the tree.

Also in the family of insertAdjacent there is the sibling methods:

element.insertAdjacentHTML('afterbegin','htmlText') for inject html string directly, like innerHTML but without overide everything , so you can jump oppressive process of document.createElement and even build whole componet with string manipulation process

element.insertAdjacentText for inject sanitize string into element . no more encode/decode

In case you need this to write a .properties file you can just add the Strings into a Properties object and then save it to a file. It will take care for the conversion.

In vb.net you can actually compare strings with =. Even though String is a reference type, in vb.net = on String has been redefined to do a case-sensitive comparison of contents of the two strings.

You can test this with the following code. Note that I have taken one of the values from user input to ensure that the compiler cannot use the same reference for the two variables like the Java compiler would if variables were defined from the same string Literal. Run the program, type "This" and press <Enter>.

Sub Main()
    Dim a As String = New String("This")
    Dim b As String

    b = Console.ReadLine()

    If a = b Then
        Console.WriteLine("They are equal")
    Else
        Console.WriteLine("Not equal")
    End If
    Console.ReadLine()
End Sub

Regular expression to get a string between two strings in JavaScript

The most complete solution that will work in the vast majority of cases is using a capturing group with a lazy dot matching pattern. However, a dot . in JavaScript regex does not match line break characters, so, what will work in 100% cases is a [^] or [\s\S]/[\d\D]/[\w\W] constructs.

ECMAScript 2018 and newer compatible solution

In JavaScript environments supporting ECMAScript 2018, s modifier allows . to match any char including line break chars, and the regex engine supports lookbehinds of variable length. So, you may use a regex like

var result = s.match(/(?<=cow\s+).*?(?=\s+milk)/gs); // Returns multiple matches if any
// Or
var result = s.match(/(?<=cow\s*).*?(?=\s*milk)/gs); // Same but whitespaces are optional

In both cases, the current position is checked for cow with any 1/0 or more whitespaces after cow, then any 0+ chars as few as possible are matched and consumed (=added to the match value), and then milk is checked for (with any 1/0 or more whitespaces before this substring).

Scenario 1: Single-line input

This and all other scenarios below are supported by all JavaScript environments. See usage examples at the bottom of the answer.

cow (.*?) milk

cow is found first, then a space, then any 0+ chars other than line break chars, as few as possible as *? is a lazy quantifier, are captured into Group 1 and then a space with milk must follow (and those are matched and consumed, too).

Scenario 2: Multiline input

cow ([\s\S]*?) milk

Here, cow and a space are matched first, then any 0+ chars as few as possible are matched and captured into Group 1, and then a space with milk are matched.

Scenario 3: Overlapping matches

If you have a string like >>>15 text>>>67 text2>>> and you need to get 2 matches in-between >>>+number+whitespace and >>>, you can't use />>>\d+\s(.*?)>>>/g as this will only find 1 match due to the fact the >>> before 67 is already consumed upon finding the first match. You may use a positive lookahead to check for the text presence without actually "gobbling" it (i.e. appending to the match):

/>>>\d+\s(.*?)(?=>>>)/g

See the online regex demo yielding text1 and text2 as Group 1 contents found.

Also see How to get all possible overlapping matches for a string.

Performance considerations

Lazy dot matching pattern (.*?) inside regex patterns may slow down script execution if very long input is given. In many cases, unroll-the-loop technique helps to a greater extent. Trying to grab all between cow and milk from "Their\ncow\ngives\nmore\nmilk", we see that we just need to match all lines that do not start with milk, thus, instead of cow\n([\s\S]*?)\nmilk we can use:

/cow\n(.*(?:\n(?!milk$).*)*)\nmilk/gm

See the regex demo (if there can be \r\n, use /cow\r?\n(.*(?:\r?\n(?!milk$).*)*)\r?\nmilk/gm). With this small test string, the performance gain is negligible, but with very large text, you will feel the difference (especially if the lines are long and line breaks are not very numerous).

Sample regex usage in JavaScript:

_x000D_

_x000D_

//Single/First match expected: use no global modifier and access match[1]
console.log("My cow always gives milk".match(/cow (.*?) milk/)[1]);
// Multiple matches: get multiple matches with a global modifier and
// trim the results if length of leading/trailing delimiters is known
var s = "My cow always gives milk, thier cow also gives milk";
console.log(s.match(/cow (.*?) milk/g).map(function(x) {return x.substr(4,x.length-9);}));
//or use RegExp#exec inside a loop to collect all the Group 1 contents
var result = [], m, rx = /cow (.*?) milk/g;
while ((m=rx.exec(s)) !== null) {
  result.push(m[1]);
}
console.log(result);

_x000D_

_x000D_

_x000D_

Using the modern String#matchAll method

_x000D_

_x000D_

const s = "My cow always gives milk, thier cow also gives milk";
const matches = s.matchAll(/cow (.*?) milk/g);
console.log(Array.from(matches, x => x[1]));

_x000D_

_x000D_

_x000D_

It happens when $ret hasn't been defined. The solution is simple. Right above $tags = get_tags();, add the following line:

The best place to demystify this is the source code. The docs are woefully inadequate about explaining this.

dispatchTouchEvent is actually defined on Activity, View and ViewGroup. Think of it as a controller which decides how to route the touch events.

For example, the simplest case is that of View.dispatchTouchEvent which will route the touch event to either OnTouchListener.onTouch if it's defined or to the extension method onTouchEvent.

For ViewGroup.dispatchTouchEvent things are way more complicated. It needs to figure out which one of its child views should get the event (by calling child.dispatchTouchEvent). This is basically a hit testing algorithm where you figure out which child view's bounding rectangle contains the touch point coordinates.

But before it can dispatch the event to the appropriate child view, the parent can spy and/or intercept the event all together. This is what onInterceptTouchEvent is there for. So it calls this method first before doing the hit testing and if the event was hijacked (by returning true from onInterceptTouchEvent) it sends a ACTION_CANCEL to the child views so they can abandon their touch event processing (from previous touch events) and from then onwards all touch events at the parent level are dispatched to onTouchListener.onTouch (if defined) or onTouchEvent(). Also in that case, onInterceptTouchEvent is never called again.

Would you even want to override [Activity|ViewGroup|View].dispatchTouchEvent? Unless you are doing some custom routing you probably should not.

The main extension methods are ViewGroup.onInterceptTouchEvent if you want to spy and/or intercept touch event at the parent level and View.onTouchListener/View.onTouchEvent for main event handling.

All in all its overly complicated design imo but android apis lean more towards flexibility than simplicity.

With a union, you're only supposed to use one of the elements, because they're all stored at the same spot. This makes it useful when you want to store something that could be one of several types. A struct, on the other hand, has a separate memory location for each of its elements and they all can be used at once.

To give a concrete example of their use, I was working on a Scheme interpreter a little while ago and I was essentially overlaying the Scheme data types onto the C data types. This involved storing in a struct an enum indicating the type of value and a union to store that value.

union foo {
  int a;   // can't use both a and b at once
  char b;
} foo;

struct bar {
  int a;   // can use both a and b simultaneously
  char b;
} bar;

union foo x;
x.a = 3; // OK
x.b = 'c'; // NO! this affects the value of x.a!

struct bar y;
y.a = 3; // OK
y.b = 'c'; // OK

edit: If you're wondering what setting x.b to 'c' changes the value of x.a to, technically speaking it's undefined. On most modern machines a char is 1 byte and an int is 4 bytes, so giving x.b the value 'c' also gives the first byte of x.a that same value:

union foo x;
x.a = 3;
x.b = 'c';
printf("%i, %i\n", x.a, x.b);

prints

99, 99

Why are the two values the same? Because the last 3 bytes of the int 3 are all zero, so it's also read as 99. If we put in a larger number for x.a, you'll see that this is not always the case:

union foo x;
x.a = 387439;
x.b = 'c';
printf("%i, %i\n", x.a, x.b);

prints

387427, 99

To get a closer look at the actual memory values, let's set and print out the values in hex:

union foo x;
x.a = 0xDEADBEEF;
x.b = 0x22;
printf("%x, %x\n", x.a, x.b);

prints

deadbe22, 22

You can clearly see where the 0x22 overwrote the 0xEF.

BUT

In C, the order of bytes in an int are not defined. This program overwrote the 0xEF with 0x22 on my Mac, but there are other platforms where it would overwrite the 0xDE instead because the order of the bytes that make up the int were reversed. Therefore, when writing a program, you should never rely on the behavior of overwriting specific data in a union because it's not portable.

For more reading on the ordering of bytes, check out endianness.

decorate your model like this. can use a bootstrap date time picker I used this one. https://github.com/Eonasdan/bootstrap-datetimepicker/

I suppose you already have bundles for bootstrap css and js

Your date picker bundle entries

 bundles.Add(new ScriptBundle("~/bundles/datePicker").Include(
           "~/Scripts/moment.min.js",
           "~/Scripts/bootstrap-datetimepicker.min.js"));

        bundles.Add(new StyleBundle("~/Content/datepicker").Include(
                 "~/Content/bootstrap-datetimepicker.min.css"));

Render bundles on your Layout View

@Styles.Render("~/Content/datepicker")
@Scripts.Render("~/bundles/datePicker")

Your HTML in view

<div class="form-group">
        @Html.LabelFor(model => model.BirthDate, htmlAttributes: new { @class = "lead col-md-2" })
        <div class="col-md-10">
            @Html.TextBoxFor(model => model.BirthDate, new { @class = "datetimepicker form-control" })
            @Html.ValidationMessageFor(model => model.BirthDate, "", new { @class = "text-danger" })
        </div>
</div>

At the end of your view add this.

<script>
    $(document).ready(function () {
        $('.datetimepicker').datetimepicker({
            format: 'lll'
        });
    });
</script>

Using awk only

foo="uNcapItalizedstrIng"
echo $foo | awk '{print toupper(substr($0,0,1))tolower(substr($0,2))}'

Yet another answer with a few extra features like support for quoted values that contain escaped quotes and CR/LF characters (single values that span multiple lines).

NOTE: Though the solution below can likely be adapted for other regex engines, using it as-is will require that your regex engine treats multiple named capture groups using the same name as one single capture group. (.NET does this by default)

When multiple lines/records of a CSV file/stream (matching RFC standard 4180) are passed to the regular expression below it will return a match for each non-empty line/record. Each match will contain a capture group named Value that contains the captured values in that line/record (and potentially an OpenValue capture group if there was an open quote at the end of the line/record).

Here's the commented pattern (test it on Regexstorm.net):

(?<=\r|\n|^)(?!\r|\n|$)                       // Records start at the beginning of line (line must not be empty)
(?:                                           // Group for each value and a following comma or end of line (EOL) - required for quantifier (+?)
  (?:                                         // Group for matching one of the value formats before a comma or EOL
    "(?<Value>(?:[^"]|"")*)"|                 // Quoted value -or-
    (?<Value>(?!")[^,\r\n]+)|                 // Unquoted value -or-
    "(?<OpenValue>(?:[^"]|"")*)(?=\r|\n|$)|   // Open ended quoted value -or-
    (?<Value>)                                // Empty value before comma (before EOL is excluded by "+?" quantifier later)
  )
  (?:,|(?=\r|\n|$))                           // The value format matched must be followed by a comma or EOL
)+?                                           // Quantifier to match one or more values (non-greedy/as few as possible to prevent infinite empty values)
(?:(?<=,)(?<Value>))?                         // If the group of values above ended in a comma then add an empty value to the group of matched values
(?:\r\n|\r|\n|$)                              // Records end at EOL

Here's the raw pattern without all the comments or whitespace.

(?<=\r|\n|^)(?!\r|\n|$)(?:(?:"(?<Value>(?:[^"]|"")*)"|(?<Value>(?!")[^,\r\n]+)|"(?<OpenValue>(?:[^"]|"")*)(?=\r|\n|$)|(?<Value>))(?:,|(?=\r|\n|$)))+?(?:(?<=,)(?<Value>))?(?:\r\n|\r|\n|$)

Here is a visualization from Debuggex.com (capture groups named for clarity):

Examples on how to use the regex pattern can be found on my answer to a similar question here, or on C# pad here, or here.

FYI, sender and e are not specific to ASP.NET or to C#. See Events (C# Programming Guide) and Events in Visual Basic.

There is also read_csv in Pandas, which is fast and supports non-comma column separators and automatic typing by column:

import pandas as pd
df = pd.read_csv('your_file',sep='\t')

It can be converted to a NumPy array if you prefer that type with:

import numpy as np
arr = np.array(df)

This is by far the easiest and most mature text import approach I've come across.

/*

If your delimiters are slash-based, escape it:

\/*

* means "0 or more of the previous repeatable pattern", which can be a single character, a character class or a group.

Would it be as easy as running a LINQ query on your List?

List<string> mylist = new List<string>{ "hello","world","foo","bar"};
List<string> listContainingLetterO = mylist.Where(x=>x.Contains("o")).ToList();

If you want to set something on a timer, you can use JavaScript's setTimeout or setInterval methods:

setTimeout ( expression, timeout );
setInterval ( expression, interval );

Where expression is a function and timeout and interval are integers in milliseconds. setTimeout runs the timer once and runs the expression once whereas setInterval will run the expression every time the interval passes.

So in your case it would work something like this:

setInterval(function() {
    //call $.ajax here
}, 5000); //5 seconds

As far as the Ajax goes, see jQuery's ajax() method. If you run an interval, there is nothing stopping you from calling the same ajax() from other places in your code.

If what you want is for an interval to run every 30 seconds until a user initiates a form submission...and then create a new interval after that, that is also possible:

setInterval() returns an integer which is the ID of the interval.

var id = setInterval(function() {
    //call $.ajax here
}, 30000); // 30 seconds

If you store that ID in a variable, you can then call clearInterval(id) which will stop the progression.

Then you can reinstantiate the setInterval() call after you've completed your ajax form submission.

var currentDateTime = dateTime.Now();
var date=currentDateTime.Date;

You can try this :

unzip -v /your/jar.jar

This will be helpful only if your jar is executable i.e. in manifest you have defined some class as main class

Please note that this answer does download a complete copy of the data from a repository. The git remote add -f command will clone the whole repository. From the man page of git-remote:

With -f option, git fetch <name> is run immediately after the remote information is set up.

Try this:

mkdir myrepo
cd myrepo
git init
git config core.sparseCheckout true
git remote add -f origin git://...
echo "path/within_repo/to/desired_subdir/*" > .git/info/sparse-checkout
git checkout [branchname] # ex: master

Now you will find that you have a "pruned" checkout with only files from path/within_repo/to/desired_subdir present (and in that path).

Note that on windows command line you must not quote the path, i.e. you must change the 6th command with this one:

echo path/within_repo/to/desired_subdir/* > .git/info/sparse-checkout

if you don't you'll get the quotes in the sparse-checkout file, and it will not work

I faced this problem today and I was able to solve it using this Gradle plugin

It's github url is this

IF you, like me, have no idea what Gradle is but need to run a backend to do your front end work, what you need to do is find the build.gradle file that is being called to start your BE server and add this to the top:

plugins {
  id "ua.eshepelyuk.ManifestClasspath" version "1.0.0"
}

The reason the first code sample doesn't work is because the layout of the page changed. As per the warning on that page: "The translated string is fetched by the RegEx close to the bottom. This could of course change, and you have to keep it up to date." I think this should work for now, at least until they change the page again.

public string TranslateText(string input, string languagePair)
{
    string url = String.Format("http://www.google.com/translate_t?hl=en&ie=UTF8&text={0}&langpair={1}", input, languagePair);
    WebClient webClient = new WebClient();
    webClient.Encoding = System.Text.Encoding.UTF8;
    string result = webClient.DownloadString(url);
    result = result.Substring(result.IndexOf("<span title=\"") + "<span title=\"".Length);
    result = result.Substring(result.IndexOf(">") + 1);
    result = result.Substring(0, result.IndexOf("</span>"));
    return result.Trim();
}

Create a UserControl which has a RichTextBox named RTB. Now add the following dependency property:

    public FlowDocument Document
    {
        get { return (FlowDocument)GetValue(DocumentProperty); }
        set { SetValue(DocumentProperty, value); }
    }

    public static readonly DependencyProperty DocumentProperty =
        DependencyProperty.Register("Document", typeof(FlowDocument), typeof(RichTextBoxControl), new PropertyMetadata(OnDocumentChanged));

    private static void OnDocumentChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        RichTextBoxControl control = (RichTextBoxControl) d;
        FlowDocument document = e.NewValue as FlowDocument;
        if (document  == null)
        {
            control.RTB.Document = new FlowDocument(); //Document is not amused by null :)
        }
        else
        {
            control.RTB.Document = document;
        }
    }

This solution is probably that "proxy" solution you saw somewhere.. However.. RichTextBox simply does not have Document as DependencyProperty... So you have to do this in another way...

Web application context, specified by the WebApplicationContext interface, is a Spring application context for a web applications. It has all the properties of a regular Spring application context, given that the WebApplicationContext interface extends the ApplicationContext interface, and add a method for retrieving the standard Servlet API ServletContext for the web application.

In addition to the standard Spring bean scopes singleton and prototype, there are three additional scopes available in a web application context:

• request - scopes a single bean definition to the lifecycle of a single HTTP request; that is, each HTTP request has its own instance of a bean created off the back of a single bean definition
• session - scopes a single bean definition to the lifecycle of an HTTP Session
• application - scopes a single bean definition to the lifecycle of a ServletContext

First off, EC2 and Elastic Compute Cloud are the same thing.

Next, AWS encompasses the range of Web Services that includes EC2 and Elastic Beanstalk. It also includes many others such as S3, RDS, DynamoDB, and all the others.

EC2

EC2 is Amazon's service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n number of instances.

Elastic Beanstalk

Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS. Elastic Beanstalk doesn't add any cost on top of these resources that it creates for you. If you have 10 hours of EC2 usage, then all you pay is 10 compute hours.

Running Wordpress

For running Wordpress, it is whatever you are most comfortable with. You could run it straight on a single EC2 instance, you could use a solution from the AWS Marketplace, or you could use Elastic Beanstalk.

What to pick?

In the case that you want to reduce system operations and just focus on the website, then Elastic Beanstalk would be the best choice for that. Elastic Beanstalk supports a PHP stack (as well as others). You can keep your site in version control and easily deploy to your environment whenever you make changes. It will also setup an Autoscaling group which can spawn up more EC2 instances if traffic is growing.

Here's the first result off of Google when searching for "elastic beanstalk wordpress": https://www.otreva.com/blog/deploying-wordpress-amazon-web-services-aws-ec2-rds-via-elasticbeanstalk/

If you just want an inline IF (without the ELSE), you can use the logical AND operator:

(a < b) && /*your code*/;

If you need an ELSE also, use the ternary operation that the other people suggested.

The Visual jQuery site has some great examples of jQuery's array functionality. (Click "Utilities" on the left-hand tab, and then "Array and Object operations".)

What is the best place is your question. The best place is inside the Controller.Initialize method. MSDN writes that it is called after the constructor and before the action method. In contrary of overriding OnActionExecuting, placing your code in the Initialize method allow you to benefit of having all custom data annotation and attribute on your classes and on your properties to be localized.

For example, my localization logic come from an class that is injected to my custom controller. I have access to this object since Initialize is called after the constructor. I can do the Thread's culture assignation and not having every error message displayed correctly.

 public BaseController(IRunningContext runningContext){/*...*/}

 protected override void Initialize(RequestContext requestContext)
 {
     base.Initialize(requestContext);
     var culture = runningContext.GetCulture();
     Thread.CurrentThread.CurrentUICulture = culture;
     Thread.CurrentThread.CurrentCulture = culture;
 }

Even if your logic is not inside a class like the example I provided, you have access to the RequestContext which allow you to have the URL and HttpContext and the RouteData which you can do basically any parsing possible.

My favorite & elegant JS objects clone solution is

function CloneObject() {}
function cloneObject(o) {
   CloneObject.prototype = o;
   return new CloneObject();
}

Use cloneObject(object) to get a clone of JS object.

Unlike many copy solutions this clone keeps prototype relationship in cloned object.

You can use the centos-sclo-rh-testing repo to install GCC v7 without having to compile it forever, also enable V7 by default and let you switch between different versions if required.

sudo yum install -y yum-utils centos-release-scl;
sudo yum -y --enablerepo=centos-sclo-rh-testing install devtoolset-7-gcc;
echo "source /opt/rh/devtoolset-7/enable" | sudo tee -a /etc/profile;
source /opt/rh/devtoolset-7/enable;
gcc --version;

Here's a simple approach using ng-init that doesn't even require a custom directive. It's worked well for me in certain scenarios e.g. needing to auto-scroll a div of ng-repeated items to a particular item on page load, so the scrolling function needs to wait until the ng-repeat has finished rendering to the DOM before it can fire.

<div ng-controller="MyCtrl">
    <div ng-repeat="thing in things">
        thing: {{ thing }}
    </div>
    <div ng-init="fireEvent()"></div>
</div>

myModule.controller('MyCtrl', function($scope, $timeout){
    $scope.things = ['A', 'B', 'C'];

    $scope.fireEvent = function(){

        // This will only run after the ng-repeat has rendered its things to the DOM
        $timeout(function(){
            $scope.$broadcast('thingsRendered');
        }, 0);

    };
});

Note that this is only useful for functions you need to call one time after the ng-repeat renders initially. If you need to call a function whenever the ng-repeat contents are updated then you'll have to use one of the other answers on this thread with a custom directive.

If you have 300 columns as you mentioned in another comment, and you want to compare on all columns (assuming the columns are all the same name), you can use a NATURAL LEFT JOIN to implicitly join on all matching column names between the two tables so that you don't have to tediously type out all join conditions manually:

SELECT            a.*
FROM              tbl_1 a
NATURAL LEFT JOIN tbl_2 b
WHERE             b.FirstName IS NULL

DECLARE @String NVARCHAR(MAX);
USE Databse Name;
SELECT @String
    =
(
    SELECT 'ALTER INDEX [' + dbindexes.[name] + '] ON [' + db.name + '].[' + dbschemas.[name] + '].[' + dbtables.[name]
           + '] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = PAGE);' + CHAR(10) AS [text()]
    FROM sys.dm_db_index_physical_stats(DB_ID(), NULL, NULL, NULL, NULL) AS indexstats
        INNER JOIN sys.tables dbtables
            ON dbtables.[object_id] = indexstats.[object_id]
        INNER JOIN sys.schemas dbschemas
            ON dbtables.[schema_id] = dbschemas.[schema_id]
        INNER JOIN sys.indexes AS dbindexes
            ON dbindexes.[object_id] = indexstats.[object_id]
               AND indexstats.index_id = dbindexes.index_id
        INNER JOIN sys.databases AS db
            ON db.database_id = indexstats.database_id
    WHERE dbindexes.name IS NOT NULL
          AND indexstats.database_id = DB_ID()
          AND indexstats.avg_fragmentation_in_percent >= 10
    ORDER BY indexstats.page_count DESC
    FOR XML PATH('')

You could just nest the Text components with the required style. The style will be applied along with already defined style in the first Text component.

 </Text>

CSS 3 introduces rgba colour, and you can combine it with graphics for a backwards compatible solution.

If you ARE very very lazy, you can put the values inside an array. Such as

list = []
list.append(x)
list.append(y)
list.append(z)
nums = [add numbers here]
letters = [add corresponding letters here]
for index in range(len(nums)):
    for obj in list:
        if obj == num[index]:
            MyList.append(letters[index])
            break

You can also put the numbers and letters in a dictionary and do it, but this is probably a LOT more complicated than simply if statements. That's what you get for trying to be extra lazy :)

One more thing, your

if x or y or z == 0:

will compile, but not in the way you want it to. When you simply put a variable in an if statement (example)

if b

the program will check if the variable is not null. Another way to write the above statement (which makes more sense) is

if bool(b)

Bool is an inbuilt function in python which basically does the command of verifying a boolean statement (If you don't know what that is, it is what you are trying to make in your if statement right now :))

Another lazy way I found is :

if any([x==0, y==0, z==0])

If you have an element that does not have a specific selector and you still want to check if it is a descendant of another element, you can use jQuery.contains()

jQuery.contains( container, contained )
Description: Check to see if a DOM element is a descendant of another DOM element.

You can pass the parent element and the element that you want to check to that function and it returns if the latter is a descendant of the first.

You can concat many kind of expression by sorrounding your simple/complex expression between || characters:

<p th:text="|${bean.field} ! ${bean.field}|">Static content</p>

I found a simpler fix...

Although the icon was green WAMP still needs to be "Put Online" (last item of menu when left-clicking icon).

After that I had access as normal.

Remember that, converting from List to Set will remove duplicates from collection because List supports duplicates but Set does not support duplicates in Java.

Direct Conversion : The most common and simple way to convert a List to a Set

// Creating a list of strings
List<String> list = Arrays.asList("One", "Two", "Three", "Four");

// Converting a list to set
Set<String> set = new HashSet<>(list);

Apache Commons Collections : You may also use the Commons Collections API to convert a List to a Set :-

// Creating a list of strings
List<String> list = Arrays.asList("One", "Two", "Three", "Four");

// Creating a set with the same number of members in the list 
Set<String> set = new HashSet<>(4);

// Adds all of the elements in the list to the target set
CollectionUtils.addAll(set, list);

Using Stream : Another way is to convert given list to stream, then stream to set :-

// Creating a list of strings 
List<String> list = Arrays.asList("One", "Two", "Three", "Four"); 

// Converting to set using stream 
Set<String> set = list.stream().collect(Collectors.toSet()); 

A simple example where the operator checks if player's id is 1 and sets enemy id depending on the result

player_id=1
....
player_id==1? enemy_id=2 : enemy_id=1
# => enemy=2

And I found a post about to the topic which seems pretty helpful.

alert (product.UnitName + " " + product.UnitPrice + " " + product.Stock)

or else create a toString() method on your object and call

alert(product.toString())

But I have to agree with other posters - if it is debugging you're going for then firebug or F12 on IE9 or chrome and using console.log is the way to go

or by pure js, see also on StackOverflow : JavaScript post request like a form submit

BUT WHY try to set $_session with js? any JS variable can be modified by a player with some 3rd party tools (firebug), thus any player can mod the $_session[]! And PHP cant give js any secret codes (or even [rolling] encrypted) to return, it is all visible. Jquery or AJAX can't help, it's all js in the end.

This happens in online game design a lot. (Maybe a bit of Game Theory? forgive me, I have a masters and love to put theory to use :) ) Like in crimegameonline.com, I initialize a minigame puzzle with PHP, saving the initial board in $_SESSION['foo']. Then, I use php to [make html that] shows the initial puzzle start. Then, js takes over, watching buttons and modding element xy's as players make moves. I DONT want to play client-server (like WOW) and ask the server 'hey, my player want's to move to xy, what should I do?'. It's a lot of bandwidth, I don't want the server that involved.

And I can just send POSTs each time the player makes an error (or dies). The player can block outgoing POSTs (and alter local JS vars to make it forget the out count) or simply modify outgoing POST data. YES, people will do this, especially if real money is involved.

If the game is small, you could send post updates EACH move (button click), 1-way, with post vars of the last TWO moves. Then, the server sanity checks last and cats new in a $_SESSION['allMoves']. If the game is massive, you could just send a 'halfway' update of all preceeding moves, and see if it matches in the final update's list.

Then, after a js thinks we have a win, add or mod a button to change pages:

document.getElementById('but1').onclick=Function("leave()");
...
function leave() {
    var line='crimegameonline-p9b.php';
    top.location.href=line;
}

Then the new page's PHP looks at $_SESSION['init'] and plays thru each of the $_SESSION['allMoves'] to see if it is really a winner. The server (PHP) must decide if it is really a winner, not the client (js).

For anyone getting to this thread late, you may want to take a look back at the .Net Base Class Library (BCL). Many people missed the changes between .Net 1.1 and .Net 2.0 when the TraceSource class was introduced (circa 2005).

Using the TraceSource is analagous to other logging frameworks, with granular control of logging, configuration in app.config/web.config, and programmatic access - without the overhead of the enterprise application block.

• .Net BCL Team Blog: Intro to Tracing - Part I (Look at Part II a,b,c as well)

There are also a number of comparisons floating around: "log4net vs TraceSource"

Using Math.Round():

int percentComplete = (int)Math.Round((double)(100 * complete) / total);

or manually rounding:

int percentComplete = (int)(0.5f + ((100f * complete) / total));

Firstly a quick recap on RSA key generation.

1. Randomly pick two random probable primes of the appropriate size (p and q).
2. Multiply the two primes together to produce the modulus (n).
3. Pick a public exponent (e).
4. Do some math with the primes and the public exponent to produce the private exponent (d).

The public key consists of the modulus and the public exponent.

A minimal private key would consist of the modulus and the private exponent. There is no computationally feasible surefire way to go from a known modulus and private exponent to the corresponding public exponent.

However:

1. Practical private key formats nearly always store more than n and d.
2. e is normally not picked randomly, one of a handful of well-known values is used. If e is one of the well-known values and you know d then it would be easy to figure out e by trial and error.

So in most practical RSA implementations you can get the public key from the private key. It would be possible to build a RSA based cryptosystem where this was not possible, but it is not the done thing.

The following configs works on Cent OS 6 or earlier

As stated above first have to disable selinux.

Step 1 nano /etc/sysconfig/selinux

Make sure the file has this configurations

SELINUX=disabled

SELINUXTYPE=targeted

Then restart the system

Step 2

iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT

Step 3

sudo service iptables save

For Cent OS 7

step 1

firewall-cmd --zone=public --permanent --add-port=8080/tcp

Step 2

firewall-cmd --reload

I suppose your html page is hosted on a different port. Same origin policy requires in most browsers that the loaded file be on the same port than the loading file.

I already gave my +1 to Jeff Yates' solution.

Here is a quick explanation why your approach does not work. This:

//ul[@class='featureList' and contains(li, 'Model')]

encounters a limitation of the contains() function (or any other string function in XPath, for that matter).

The first argument is supposed to be a string. If you feed it a node list (giving it "li" does that), a conversion to string must take place. But this conversion is done for the first node in the list only.

In your case the first node in the list is <li><b>Type:</b> Clip Fan</li> (converted to a string: "Type: Clip Fan") which means that this:

//ul[@class='featureList' and contains(li, 'Type')]

would actually select a node!

a = np.array([1,2,3])
b = np.array([4,5,6])
np.array((a,b))

works just as well as

np.array([[1,2,3], [4,5,6]])

Regardless of whether it is a list of lists or a list of 1d arrays, np.array tries to create a 2d array.

But it's also a good idea to understand how np.concatenate and its family of stack functions work. In this context concatenate needs a list of 2d arrays (or any anything that np.array will turn into a 2d array) as inputs.

np.vstack first loops though the inputs making sure they are at least 2d, then does concatenate. Functionally it's the same as expanding the dimensions of the arrays yourself.

np.stack is a new function that joins the arrays on a new dimension. Default behaves just like np.array.

Look at the code for these functions. If written in Python you can learn quite a bit. For vstack:

return _nx.concatenate([atleast_2d(_m) for _m in tup], 0)

You can use this dummy plugin:

mvn archetype:generate -DgroupId=org.eclipse.m2e -DartifactId=lifecycle-mapping -Dversion=1.0.0 -DarchetypeArtifactId=maven-archetype-mojo

After generating the project install/deploy it.

I use

            chartRange = xlWorkSheet.Rows[1];
            chartRange.Font.Bold = true;

to turn the first-row-cells-font into bold. And it works, and I am using also Excel 2007.

You can call in VBA directly

            ActiveCell.Font.Bold = True

With this code I create a timestamp in the active cell, with bold font and yellow background

           Private Sub Worksheet_SelectionChange(ByVal Target As Range)
               ActiveCell.Value = Now()
               ActiveCell.Font.Bold = True
               ActiveCell.Interior.ColorIndex = 6
           End Sub

If you are using Excel 2013 Than do the following File > Option > Advanced > Under Display options for this worksheet: uncheck the checkbox before Show formulas in cells instead of their calculated results This should resolve the issue.

Whammo blammo (for leading spaces):

SELECT 
    RIGHT(space(60) + cust_name, 60),
    RIGHT(space(60) + cust_address, 60)

OR (for trailing spaces)

SELECT
    LEFT(cust_name + space(60), 60),
    LEFT(cust_address + space(60), 60),

This should work as well. Use quotes to maintain space

<string name="spelatonertext3">"-4,  5, -5,   6,  -6,"</string>

Look at this:

#!/usr/bin/python

import datetime

def addYears(date, years):
    result = date + datetime.timedelta(366 * years)
    if years > 0:
        while result.year - date.year > years or date.month < result.month or date.day < result.day:
            result += datetime.timedelta(-1)
    elif years < 0:
        while result.year - date.year < years or date.month > result.month or date.day > result.day:
            result += datetime.timedelta(1)
    print "input: %s output: %s" % (date, result)
    return result

Example usage:

addYears(datetime.date(2012,1,1), -1)
addYears(datetime.date(2012,1,1), 0)
addYears(datetime.date(2012,1,1), 1)
addYears(datetime.date(2012,1,1), -10)
addYears(datetime.date(2012,1,1), 0)
addYears(datetime.date(2012,1,1), 10)

And output of this example:

input: 2012-01-01 output: 2011-01-01
input: 2012-01-01 output: 2012-01-01
input: 2012-01-01 output: 2013-01-01
input: 2012-01-01 output: 2002-01-01
input: 2012-01-01 output: 2012-01-01
input: 2012-01-01 output: 2022-01-01

Don't use an array if you want named keys, use a plain object.

var a = {};
a["key1"] = "value1";
a["key2"] = "value2";

Then:

if ("key1" in a) {
   // something
} else {
   // something else 
}

This is possible! At least now that css transforms have good support:

You need to use a CSS transform to scale the image - the trick is not just to use a scale(), but also to apply a very small rotation. This triggers IE to use a smoother interpolation of the image:

img {
    /* double desired size */
    width: 56px; 
    height: 56px;

    /* margins to reduce layout size to match the transformed size */ 
    margin: -14px -14px -14px -14px; 

    /* transform to scale with smooth interpolation: */
    transform: scale(0.5) rotate(0.1deg);
}

Because the bootstrap-select is a bootstrap component and therefore you need to include it in your code as you did for your V3

NOTE: this component only works in boostrap-4 since version 1.13.0

$('select').selectpicker();

is the ajax uploader refreshing your input element? if so you should consider using .live() method.

 $('#imageFile').live('change', function(){ uploadFile(); });

update:

from jQuery 1.7+ you should use now .on()

 $(parent_element_selector_here or document ).on('change','#imageFile' , function(){ uploadFile(); });

One way to solve this error is to put the ForeignKey attribute on top of the property you want as a foreign key and add the navigation property.

Note: In the ForeignKey attribute, between parentheses and double quotes, place the name of the class referred to in this way.

@Grantismo provides a great explanation on the overall. If you wish to know who people are actually doing this things i suggest you to take a look at how google did for the Google IO App of 2014 (it's always worth taking a deep look at the source code of these apps that they release. There's a lot to learn from there).

Here's a blog post about it: http://android-developers.blogspot.com.br/2014/09/conference-data-sync-gcm-google-io.html

Essentially, on the application side: GCM for signalling, Sync Adapter for data fetching and talking properly with Content Provider that will make things persistent (yeah, it isolates the DB from direct access from other parts of the app).

Also, if you wish to take a look at the 2015's code: https://github.com/google/iosched

This is probably what you need:

$('div').html();

demo

This says get the div and return all the contents inside it. See more here: http://api.jquery.com/html/

If you had many divs on the page and needed to target just one, you could set an id on the div and call it like so

$('#whatever').html();

where whatever is the id

EDIT

Now that you have clarified your question re this being a string, here is a way to do it with vanilla js:

var l = x.length;
var y = x.indexOf('<div>');
var s = x.slice(y,l);
alert(s);

Demo Here

1. get the length of the string.
2. find out where the first div occurs
3. slice the content there.

First-level cache

Hibernate tries to defer the Persistence Context flushing up until the last possible moment. This strategy has been traditionally known as transactional write-behind.

The write-behind is more related to Hibernate flushing rather than any logical or physical transaction. During a transaction, the flush may occur multiple times.

The flushed changes are visible only for the current database transaction. Until the current transaction is committed, no change is visible by other concurrent transactions.

Due to the first-level cache, Hibernate can do several optimizations:

• JDBC statement batching
• prevent lost update anomalies

Second-level cache

A proper caching solution would have to span across multiple Hibernate Sessions and that’s the reason Hibernate supports an additional second-level cache as well.

The second-level cache is bound to the SessionFactory life-cycle, so it’s destroyed only when the SessionFactory is closed (typically when the application is shutting down). The second-level cache is primarily entity-based oriented, although it supports an optional query-caching solution as well.

When loading an entity, Hibernate will execute the following actions:

1. If the entity is stored in the first-level cache, then the cached object reference is returned. This ensures application-level repeatable reads.
2. If the entity is not stored in the first-level cache and the second-level cache is activated, then Hibernate checks if the entity has been cached in the second-level cache, and if it were, it returns it to the caller.
3. Otherwise, if the entity is not stored in the first or second-level cache, it will be loaded from the DB.

Use Query.setParameterList(), Javadoc here.

There are four variants to pick from.

In Swift 4 and 5. I created a closure variable containing two parameter dictionary and bool.

 var completionHandler:([String:Any], Bool)->Void = { dict, success  in
    if success {
      print(dict)
    }
  }

Calling the closure variable

self.completionHandler(["name":"Gurjinder singh"],true)

There's a caveat with the general 39 character IPv6 structure. For IPv4 mapped IPv6 addresses, the string can be longer (than 39 characters). An example to show this:

IPv6 (39 characters) :

ABCD:ABCD:ABCD:ABCD:ABCD:ABCD:ABCD:ABCD

IPv4-mapped IPv6 (45 characters) :

ABCD:ABCD:ABCD:ABCD:ABCD:ABCD:192.168.158.190

Note: the last 32-bits (that correspond to IPv4 address) can need up to 15 characters (as IPv4 uses 4 groups of 1 byte and is formatted as 4 decimal numbers in the range 0-255 separated by dots (the . character), so the maximum is DDD.DDD.DDD.DDD).

The correct maximum IPv6 string length, therefore, is 45.

This was actually a quiz question in an IPv6 training I attended. (We all answered 39!)

Use the following command outside the WEB-INF folder. This should create your war file and is the quickest method I know.

(You will need JDK 1.7+ installed and environment variables that point to the bin directory of your JDK.)

jar -cvf projectname.war *

Reference Link

std::fill(v.begin(), v.end(), 0);

There is another way without Promise.all() to do it in parallel:

First, we have 2 functions to print numbers:

function printNumber1() {
   return new Promise((resolve,reject) => {
      setTimeout(() => {
      console.log("Number1 is done");
      resolve(10);
      },1000);
   });
}

function printNumber2() {
   return new Promise((resolve,reject) => {
      setTimeout(() => {
      console.log("Number2 is done");
      resolve(20);
      },500);
   });
}

This is sequential:

async function oneByOne() {
   const number1 = await printNumber1();
   const number2 = await printNumber2();
} 
//Output: Number1 is done, Number2 is done

This is parallel:

async function inParallel() {
   const promise1 = printNumber1();
   const promise2 = printNumber2();
   const number1 = await promise1;
   const number2 = await promise2;
}
//Output: Number2 is done, Number1 is done

This query is for add data from one table to another table using foreign key

                                    } else {
                                        res.json("Customer added")
                                    }
                                })
                            }

                }
    
            }

    })

IIS will create it again AFAIK.

Facelets is a XML based view technology. The & is a special character in XML representing the start of an entity like & which ends with the ; character. You'd need to either escape it, which is ugly:

rendered="#{beanA.prompt == true && beanB.currentBase != null}"

or to use the and keyword instead, which is preferred as to readability and maintainability:

rendered="#{beanA.prompt == true and beanB.currentBase != null}"

See also:

• Java EE 6 tutorial - Operators in EL

Unrelated to the concrete problem, comparing booleans with booleans makes little sense when the expression expects a boolean outcome already. I'd get rid of == true:

rendered="#{beanA.prompt and beanB.currentBase != null}"

If there's any chance that your datetimes aren't strict calendar dates, you should consider using enddate exclusion comparisons... This will prevent you from missing any requests created during the date of Jan 31.

DateTime now = DateTime.Now;
DateTime thisMonth = new DateTime(now.Year, now.Month, 1);
DateTime lastMonth = thisMonth.AddMonths(-1);

var RequestIds = rdc.request
  .Where(r => lastMonth <= r.dteCreated)
  .Where(r => r.dteCreated < thisMonth)
  .Select(r => r.intRequestId);

just because you don't have the right to acess the file , use

chmod -R 755 /var/log/nginx;

or you can change to sudo then it

Bootstrap Persian version of the site http://rbootstrap.ir/ Ver.2.3.2

With Android Architecture Components through the use of LiveData this can be easily implemented with any type of Adapter. You simply have to do the following steps:

1. Setup your data to return from the Room Database as LiveData as in the example below:

@Dao
public interface CustomDAO{

@Query("SELECT * FROM words_table WHERE column LIKE :searchquery")
    public LiveData<List<Word>> searchFor(String searchquery);
}

2. Create a ViewModel object to update your data live through a method that will connect your DAO and your UI

public class CustomViewModel extends AndroidViewModel {

    private final AppDatabase mAppDatabase;

    public WordListViewModel(@NonNull Application application) {
        super(application);
        this.mAppDatabase = AppDatabase.getInstance(application.getApplicationContext());
    }

    public LiveData<List<Word>> searchQuery(String query) {
        return mAppDatabase.mWordDAO().searchFor(query);
    }

}

3. Call your data from the ViewModel on the fly by passing in the query through onQueryTextListener as below:

Inside onCreateOptionsMenu set your listener as follows

searchView.setOnQueryTextListener(onQueryTextListener);

Setup your query listener somewhere in your SearchActivity class as follows

private android.support.v7.widget.SearchView.OnQueryTextListener onQueryTextListener =
            new android.support.v7.widget.SearchView.OnQueryTextListener() {
                @Override
                public boolean onQueryTextSubmit(String query) {
                    getResults(query);
                    return true;
                }

                @Override
                public boolean onQueryTextChange(String newText) {
                    getResults(newText);
                    return true;
                }

                private void getResults(String newText) {
                    String queryText = "%" + newText + "%";
                    mCustomViewModel.searchQuery(queryText).observe(
                            SearchResultsActivity.this, new Observer<List<Word>>() {
                                @Override
                                public void onChanged(@Nullable List<Word> words) {
                                    if (words == null) return;
                                    searchAdapter.submitList(words);
                                }
                            });
                }
            };

Note: Steps (1.) and (2.) are standard AAC ViewModel and DAO implementation, the only real "magic" going on here is in the OnQueryTextListener which will update the results of your list dynamically as the query text changes.

If you need more clarification on the matter please don't hesitate to ask. I hope this helped :).

Remove them. It's idiomatic to return from case statements, and it's "unreachable code" noise otherwise.

For me the error message goes away if I unmount the old mount before mounting it again:

fusermount -u /mnt/point

If it's not already mounted you get a non-critical error:

$ fusermount -u /mnt/point

fusermount: entry for /mnt/point not found in /etc/mtab

So in my script I just put unmount it before mounting it.

when(
  fooDao.getBar(
    any(Bazoo.class)
  )
).thenReturn(myFoo);

or (to avoid nulls):

when(
  fooDao.getBar(
    (Bazoo)notNull()
  )
).thenReturn(myFoo);

Don't forget to import matchers (many others are available):

For Mockito 2.1.0 and newer:

import static org.mockito.ArgumentMatchers.*;

For older versions:

import static org.mockito.Matchers.*;

Since I cannot comment, adding this note in addition to @jethro answer.

I found out that you also need to do the FOREIGN KEY line as the last part of create the table statement, otherwise you will get a syntax error when installing your app. What I mean is, you cannot do something like this:

private static final String TASK_TABLE_CREATE = "create table "
    + TASK_TABLE + " (" + TASK_ID
    + " integer primary key autoincrement, " + TASK_TITLE
    + " text not null, " + TASK_NOTES + " text not null, "
+ TASK_CAT + " integer,"
+ " FOREIGN KEY ("+TASK_CAT+") REFERENCES "+CAT_TABLE+" ("+CAT_ID+"), "
+ TASK_DATE_TIME + " text not null);";

Where I put the TASK_DATE_TIME after the foreign key line.

Use some regex like [0-9] or \d:

$words = preg_replace('/\d+/', '', $words );

You might want to read the preg_replace() documentation as this is directly shown there.

var link = $(element);
var offset = link.offset();

var top = offset.top;
var left = offset.left;

var bottom = top + link.outerHeight();
var right = left + link.outerWidth();

I just copied tools.jar file from JDK\lib folder to JRE\lib folder. Since then it worked like a champ.

Surprised that I did not see the below query selector way solution,

document.querySelector('#xyz').style.paddingTop = "10px"

CSSStyleDeclaration solutions, an example of the accepted answer

document.getElementById('xyz').style.paddingTop = "10px";

Async/Await with axios 

  useEffect(() => {     
    const getData = async () => {  
      await axios.get('your_url')  
      .then(res => {  
        console.log(res)  
      })  
      .catch(err => {  
        console.log(err)  
      });  
    }  
    getData()  
  }, [])

basename($_SERVER['REQUEST_URI']) returns everything after and including the '?',

In my code sometimes I need only sections, so separate it out so I can get the value of what I need on the fly. Not sure on the performance speed compared to other methods, but it's really useful for me.

$urlprotocol = 'http'; if ($_SERVER["HTTPS"] == "on") {$urlprotocol .= "s";} $urlprotocol .= "://";
$urldomain = $_SERVER["SERVER_NAME"];
$urluri = $_SERVER['REQUEST_URI'];
$urlvars = basename($urluri);
$urlpath = str_replace($urlvars,"",$urluri);

$urlfull = $urlprotocol . $urldomain . $urlpath . $urlvars;

With ugrep released a few months ago:

ugrep 'abc(\n|.)+?efg'

This tool is highly optimized for speed. It's also GNU/BSD/PCRE-grep compatible.

Note that we should use a lazy repetition +?, unless you want to match all lines with efg together until the last efg in the file.

It should be like this.

In your Component

computed: {
        ...mapGetters({
                nameFromStore: 'name'
            }),
        name: {
           get(){
             return this.nameFromStore
           },
           set(newName){
             return newName
           } 
        }
    }

In your store

export const store = new Vuex.Store({
         state:{
             name : "Stackoverflow"
         },
         getters: {
                 name: (state) => {
                     return state.name;
                 }
         }
}

Change your clean so rm will not complain:

clean:
    rm -f .lambda .lambda_t .activity .activity_t_lambda

=TO_DATE(TO_PURE_NUMBER(Insert Date cell, i.e. AM4)+[how many days to add in numbers, e.g. 3 days])

Looks like in practice:

=TO_DATE(TO_PURE_NUMBER(AM4)+3)

Essentially you are converting the date into a pure number and back into a date again.

There are many ways to wait in Unity. It is really simple but I think it's worth covering most ways to do these:

1.With a coroutine and WaitForSeconds.

The is by far the simplest way. Put all the code that you need to wait for some time in a coroutine function then you can wait with WaitForSeconds. Note that in coroutine function, you call the function with StartCoroutine(yourFunction).

Example below will rotate 90 deg, wait for 4 seconds, rotate 40 deg and wait for 2 seconds, and then finally rotate rotate 20 deg.

void Start()
{
    StartCoroutine(waiter());
}

IEnumerator waiter()
{
    //Rotate 90 deg
    transform.Rotate(new Vector3(90, 0, 0), Space.World);

    //Wait for 4 seconds
    yield return new WaitForSeconds(4);

    //Rotate 40 deg
    transform.Rotate(new Vector3(40, 0, 0), Space.World);

    //Wait for 2 seconds
    yield return new WaitForSeconds(2);

    //Rotate 20 deg
    transform.Rotate(new Vector3(20, 0, 0), Space.World);
}

2.With a coroutine and WaitForSecondsRealtime.

The only difference between WaitForSeconds and WaitForSecondsRealtime is that WaitForSecondsRealtime is using unscaled time to wait which means that when pausing a game with Time.timeScale, the WaitForSecondsRealtime function would not be affected but WaitForSeconds would.

void Start()
{
    StartCoroutine(waiter());
}

IEnumerator waiter()
{
    //Rotate 90 deg
    transform.Rotate(new Vector3(90, 0, 0), Space.World);

    //Wait for 4 seconds
    yield return new WaitForSecondsRealtime(4);

    //Rotate 40 deg
    transform.Rotate(new Vector3(40, 0, 0), Space.World);

    //Wait for 2 seconds
    yield return new WaitForSecondsRealtime(2);

    //Rotate 20 deg
    transform.Rotate(new Vector3(20, 0, 0), Space.World);
}

Wait and still be able to see how long you have waited:

3.With a coroutine and incrementing a variable every frame with Time.deltaTime.

A good example of this is when you need the timer to display on the screen how much time it has waited. Basically like a timer.

It's also good when you want to interrupt the wait/sleep with a boolean variable when it is true. This is where yield break; can be used.

bool quit = false;

void Start()
{
    StartCoroutine(waiter());
}

IEnumerator waiter()
{
    float counter = 0;
    //Rotate 90 deg
    transform.Rotate(new Vector3(90, 0, 0), Space.World);

    //Wait for 4 seconds
    float waitTime = 4;
    while (counter < waitTime)
    {
        //Increment Timer until counter >= waitTime
        counter += Time.deltaTime;
        Debug.Log("We have waited for: " + counter + " seconds");
        //Wait for a frame so that Unity doesn't freeze
        //Check if we want to quit this function
        if (quit)
        {
            //Quit function
            yield break;
        }
        yield return null;
    }

    //Rotate 40 deg
    transform.Rotate(new Vector3(40, 0, 0), Space.World);

    //Wait for 2 seconds
    waitTime = 2;
    //Reset counter
    counter = 0;
    while (counter < waitTime)
    {
        //Increment Timer until counter >= waitTime
        counter += Time.deltaTime;
        Debug.Log("We have waited for: " + counter + " seconds");
        //Check if we want to quit this function
        if (quit)
        {
            //Quit function
            yield break;
        }
        //Wait for a frame so that Unity doesn't freeze
        yield return null;
    }

    //Rotate 20 deg
    transform.Rotate(new Vector3(20, 0, 0), Space.World);
}

You can still simplify this by moving the while loop into another coroutine function and yielding it and also still be able to see it counting and even interrupt the counter.

bool quit = false;

void Start()
{
    StartCoroutine(waiter());
}

IEnumerator waiter()
{
    //Rotate 90 deg
    transform.Rotate(new Vector3(90, 0, 0), Space.World);

    //Wait for 4 seconds
    float waitTime = 4;
    yield return wait(waitTime);

    //Rotate 40 deg
    transform.Rotate(new Vector3(40, 0, 0), Space.World);

    //Wait for 2 seconds
    waitTime = 2;
    yield return wait(waitTime);

    //Rotate 20 deg
    transform.Rotate(new Vector3(20, 0, 0), Space.World);
}

IEnumerator wait(float waitTime)
{
    float counter = 0;

    while (counter < waitTime)
    {
        //Increment Timer until counter >= waitTime
        counter += Time.deltaTime;
        Debug.Log("We have waited for: " + counter + " seconds");
        if (quit)
        {
            //Quit function
            yield break;
        }
        //Wait for a frame so that Unity doesn't freeze
        yield return null;
    }
}

Wait/Sleep until variable changes or equals to another value:

4.With a coroutine and the WaitUntil function:

Wait until a condition becomes true. An example is a function that waits for player's score to be 100 then loads the next level.

float playerScore = 0;
int nextScene = 0;

void Start()
{
    StartCoroutine(sceneLoader());
}

IEnumerator sceneLoader()
{
    Debug.Log("Waiting for Player score to be >=100 ");
    yield return new WaitUntil(() => playerScore >= 10);
    Debug.Log("Player score is >=100. Loading next Leve");

    //Increment and Load next scene
    nextScene++;
    SceneManager.LoadScene(nextScene);
}

5.With a coroutine and the WaitWhile function.

Wait while a condition is true. An example is when you want to exit app when the escape key is pressed.

void Start()
{
    StartCoroutine(inputWaiter());
}

IEnumerator inputWaiter()
{
    Debug.Log("Waiting for the Exit button to be pressed");
    yield return new WaitWhile(() => !Input.GetKeyDown(KeyCode.Escape));
    Debug.Log("Exit button has been pressed. Leaving Application");

    //Exit program
    Quit();
}

void Quit()
{
    #if UNITY_EDITOR
    UnityEditor.EditorApplication.isPlaying = false;
    #else
    Application.Quit();
    #endif
}

6.With the Invoke function:

You can call tell Unity to call function in the future. When you call the Invoke function, you can pass in the time to wait before calling that function to its second parameter. The example below will call the feedDog() function after 5 seconds the Invoke is called.

void Start()
{
    Invoke("feedDog", 5);
    Debug.Log("Will feed dog after 5 seconds");
}

void feedDog()
{
    Debug.Log("Now feeding Dog");
}

7.With the Update() function and Time.deltaTime.

It's just like #3 except that it does not use coroutine. It uses the Update function.

The problem with this is that it requires so many variables so that it won't run every time but just once when the timer is over after the wait.

float timer = 0;
bool timerReached = false;

void Update()
{
    if (!timerReached)
        timer += Time.deltaTime;

    if (!timerReached && timer > 5)
    {
        Debug.Log("Done waiting");
        feedDog();

        //Set to false so that We don't run this again
        timerReached = true;
    }
}

void feedDog()
{
    Debug.Log("Now feeding Dog");
}

There are still other ways to wait in Unity but you should definitely know the ones mentioned above as that makes it easier to make games in Unity. When to use each one depends on the circumstances.

For your particular issue, this is the solution:

IEnumerator showTextFuntion()
{
    TextUI.text = "Welcome to Number Wizard!";
    yield return new WaitForSeconds(3f);
    TextUI.text = ("The highest number you can pick is " + max);
    yield return new WaitForSeconds(3f);
    TextUI.text = ("The lowest number you can pick is " + min);
}

And to call/start the coroutine function from your start or Update function, you call it with

StartCoroutine (showTextFuntion());

if my_list is the list that you want to store your objects in it and my_object is your object wanted to be stored, use this structure:

my_list.append(my_object)

If you already have git installed via homebrew, you can just do upgrade:

$ type -a git
/usr/bin/git
$ brew upgrade git
$ type -a git
/usr/local/bin/git

The one at local/bin will have gitk

Extending DarenW's comment.

Once typename and class are not accepted to be very different, it might be still valid to be strict on their use. Use class only if is really a class, and typename when its a basic type, such as char.

These types are indeed also accepted instead of typename

template< char myc = '/' >

which would be in this case even superior to typename or class.

Think of "hintfullness" or intelligibility to other people. And actually consider that 3rd party software/scripts might try to use the code/information to guess what is happening with the template (consider swig).

you may need to check whether the settings.xml file is correct. such as user name, password, third party url.

Reloading the configuration file (my.cnf) cannot be done without restarting the mysqld server.

FLUSH LOGS only rotates a few log files.

SET @@...=... sets it for anyone not yet logged in, but it will go away after the next restart. But that gives a clue... Do the SET, and change my.cnf; that way you are covered. Caveat: Not all settings can be performed via SET.

New with MySQL 8.0...

SET PERSIST ... will set the global setting and save it past restarts. Nearly all settings can be adjusted this way.

This problem was driving me crazy too. I was using PHP on my server side so I was not able to use @The Lazy Log(ruby) & @deweydb(python) solutions. However it pointed me to the right direction. I fixed it on the backed using Imagick's getImageOrientation().

<?php 
// Note: $image is an Imagick object, not a filename! See example use below. 
function autoRotateImage($image) { 
    $orientation = $image->getImageOrientation(); 

    switch($orientation) { 
        case imagick::ORIENTATION_BOTTOMRIGHT: 
            $image->rotateimage("#000", 180); // rotate 180 degrees 
        break; 

        case imagick::ORIENTATION_RIGHTTOP: 
            $image->rotateimage("#000", 90); // rotate 90 degrees CW 
        break; 

        case imagick::ORIENTATION_LEFTBOTTOM: 
            $image->rotateimage("#000", -90); // rotate 90 degrees CCW 
        break; 
    } 

    // Now that it's auto-rotated, make sure the EXIF data is correct in case the EXIF gets saved with the image! 
    $image->setImageOrientation(imagick::ORIENTATION_TOPLEFT); 
} 
?>

This occurs when declared (non-pure) virtual functions are missing bodies. In your class definition, something like:

virtual void foo();

Should be defined (inline or in a linked source file):

virtual void foo() {}

Or declared pure virtual:

virtual void foo() = 0;

Please try this online tool sql2builder

DB::table('products')
    ->whereIn('products.id',function($query) {
                            DB::table('product_category')
                            ->whereIn('category_id',['223','15'])
                            ->select('product_id');
                        })
    ->where('products.active',1)
    ->select('products.id','products.name','products.img','products.safe_name','products.sku','products.productstatusid')
    ->get();

You can use the visible selector:

http://api.jquery.com/visible-selector/

You can use date(t_stamp) to get only the date part from a timestamp.

You can check the date() function in the docs

DATE(expr)

Extracts the date part of the date or datetime expression expr.

mysql> SELECT DATE('2003-12-31 01:02:03'); -> '2003-12-31'

Try my JavaScript hash table implementation: http://www.timdown.co.uk/jshashtable

It looks for a hashCode() method of key objects, or you can supply a hashing function when creating a Hashtable object.

Get MAC adress for eth0:

$ cat /etc/sysconfig/network-scripts/ifcfg-eth0 | grep HWADDR | cut -c 9-25

Example:

[me@machine ~]$ cat /etc/sysconfig/network-scripts/ifcfg-eth0 | grep HWADDR | cut -c 9-25
55:b5:00:10:be:10

My issue with this was that the element using the disabled attr needed to be defined as a form element, .ie input type for it to work. Both worked with attr() and prop() but chose the latter for future maintainability.

You can also set the color individually for each point/bar if you change the data array to be configuration objects instead of numbers.

data: [
      {y: 34.4, color: 'red'},     // this point is red
      21.8,                        // default blue
      {y: 20.1, color: '#aaff99'}, // this will be greenish
      20]                          // default blue

Example on jsfiddle

It depends. The standard only demands that it is large enough to hold all values, so formally an enum like enum foo { zero, one, two }; needs to only be one byte large. However most implementations make those enums as large as ints (that's faster on modern hardware; moreover it's needed for compatibility with C where enums are basically glorified ints). Note however that C++ allows enums with initializers outside of the int range, and for those enums the size will of course also be larger. For example, if you have enum bar { a, b = 1LL << 35 }; then your enum will be larger than 32 bits (most likely 64 bits) even on a system with 32 bit ints (note that in C that enum would not be allowed).

Try this:

<tr ng-repeat="player in players | filter:{id: player_id, name:player_name} | filter:ageFilter">

$scope.ageFilter = function (player) {
    return (player.age > $scope.min_age && player.age < $scope.max_age);
}

UITableViewController does the Scrolling automatically, indeed. The difference compared to using a UIViewController is, that you have to create Navbar-Buttonitems programmatically by using the NavigationController, when using a TableViewController.

I'm using this code, pretty good. You will very easy to know user-agents visitted your site. This code is opening a file and write the user_agent down the file. You can check each day this file by go to yourdomain.com/useragent.txt and know about new user_agents and put them in your condition of if clause.

$user_agent = strtolower($_SERVER['HTTP_USER_AGENT']);
if(!preg_match("/Googlebot|MJ12bot|yandexbot/i", $user_agent)){
    // if not meet the conditions then
    // do what you need

    // here open a file and write the user_agent down the file. You can check each day this file useragent.txt and know about new user_agents and put them in your condition of if clause
    if($user_agent!=""){
        $myfile = fopen("useragent.txt", "a") or die("Unable to open file useragent.txt!");
        fwrite($myfile, $user_agent);
        $user_agent = "\n";
        fwrite($myfile, $user_agent);
        fclose($myfile);
    }
}

This is the content of useragent.txt

You might want to do it like this:

DateTime? lastPostDate =  (DateTime?)(reader.IsDbNull(3) ? null : reader[3]); 

The problem you are having is that the ternary operator wants a viable cast between the left and right sides. And null can't be cast to DateTime.

Note the above works because both sides of the ternary are object's. The object is explicitly cast to DateTime? which works: as long as reader[3] is in fact a date.

Try this

Option Explicit

Sub UniqueValues()
Dim ws As Worksheet
Dim uniqueRng As Range
Dim myCol As Long

myCol = 5 '<== set it as per your needs
Set ws = ThisWorkbook.Worksheets("unique") '<== set it as per your needs

Set uniqueRng = GetUniqueValues(ws, myCol)

End Sub


Function GetUniqueValues(ws As Worksheet, col As Long) As Range
Dim firstRow As Long

With ws
    .Columns(col).RemoveDuplicates Columns:=Array(1), header:=xlNo

    firstRow = 1
    If IsEmpty(.Cells(1, col)) Then firstRow = .Cells(1, col).End(xlDown).row

    Set GetUniqueValues = Range(.Cells(firstRow, col), .Cells(.Rows.Count, col).End(xlUp))
End With

End Function

it should be quite fast and without the drawback NeepNeepNeep told about

Other answers posted here for this question did not work for me using the latest Visual Studio 2017 Enterprise edition (as of 2018-09-18).

Instead, I used this method:

1. Close all but one instance of Visual Studio.
2. In the running instance, access the menu Tools->Extensions and Updates.
3. In that dialog, choose Online->Visual Studio Marketplace->Tools->Setup & Deployment.
4. From the list that appears, select Microsoft Visual Studio 2017 Installer Projects.

Once installed, close and restart Visual Studio. Go to File->New Project and search for the word Installer. You'll know you have the correct templates installed if you see a list that looks something like this:

2019 Update: It still depends on the browsers your demographic uses.

An important thing to understand with the "new" HTML5 file API is that it wasn't supported until IE 10. If the specific market you're aiming at has a higher-than-average propensity toward older versions of Windows, you might not have access to it.

As of 2017, about 5% of browsers are one of IE 6, 7, 8 or 9. If you head into a big corporation (e.g., this is a B2B tool, or something you're delivering for training) that number can skyrocket. In 2016, I dealt with a company using IE8 on over 60% of their machines.

It's 2019 as of this edit, almost 11 years after my initial answer. IE9 and lower are globally around the 1% mark but there are still clusters of higher usage.

The important take-away from this —whatever the feature— is, check what browser your users use. If you don't, you'll learn a quick and painful lesson in why "works for me" isn't good enough in a deliverable to a client. caniuse is a useful tool but note where they get their demographics from. They may not align with yours. This is never truer than enterprise environments.

My answer from 2008 follows.

However, there are viable non-JS methods of file uploads. You can create an iframe on the page (that you hide with CSS) and then target your form to post to that iframe. The main page doesn't need to move.

It's a "real" post so it's not wholly interactive. If you need status you need something server-side to process that. This varies massively depending on your server. ASP.NET has nicer mechanisms. PHP plain fails, but you can use Perl or Apache modifications to get around it.

If you need multiple file-uploads, it's best to do each file one at a time (to overcome maximum file upload limits). Post the first form to the iframe, monitor its progress using the above and when it has finished, post the second form to the iframe, and so on.

Or use a Java/Flash solution. They're a lot more flexible in what they can do with their posts...

I'm doing this on my raspberry pi from the command line by running:

for i in *;do omxplayer "$i";done

This may answer your question:

select cast(xmlField as xml) xmlField into tmp from (
select '<person><firstName>Jon</firstName><lastName>Johnson</lastName></person>' xmlField

union select '<person><firstName>Bob</firstName><lastName>Burns</lastName></person>'
) tb

SELECT
    xmlField.value('(person/firstName)[1]', 'nvarchar(max)') as FirstName
    ,xmlField.value('(person/lastName)[1]', 'nvarchar(max)') as LastName

PLEASE NOTE: The documentation says:

filter is a JavaScript extension to the ECMA-262 standard; as such it may not be present in other implementations of the standard. You can work around this by inserting the following code at the beginning of your scripts, allowing use of filter in ECMA-262 implementations which do not natively support it. This algorithm is exactly the one specified in ECMA-262, 5th edition, assuming that fn.call evaluates to the original value of Function.prototype.call, and that Array.prototype.push has its original value.

So, to avoid some heartache, you may have to add this code to your script At the beginning.

if (!Array.prototype.filter) {
  Array.prototype.filter = function (fn, context) {
    var i,
        value,
        result = [],
        length;
        if (!this || typeof fn !== 'function' || (fn instanceof RegExp)) {
          throw new TypeError();
        }
        length = this.length;
        for (i = 0; i < length; i++) {
          if (this.hasOwnProperty(i)) {
            value = this[i];
            if (fn.call(context, value, i, this)) {
              result.push(value);
            }
          }
        }
    return result;
  };
}

I had teh same problem and spend many hours find diferent solutions, and now I join all the comments in this post.I hope it, will be helpfull, my answer was correctly tested on Internet Explorer 11, Chrome and FireFox.

"all" and "any" are nice for the many conditions of same type case. BUT they always evaluates all conditions. As shown in this example:

def c1():
    print " Executed c1"
    return False
def c2():
    print " Executed c2"
    return False


print "simple and (aborts early!)"
if c1() and c2():
    pass

print

print "all (executes all :( )"
if all((c1(),c2())):
    pass

print

I think the variable name 'self' should not be used this way anymore, since modern browsers provide a global variable self pointing to the global object of either a normal window or a WebWorker.

To avoid confusion and potential conflicts, you can write var thiz = this or var that = this instead.

To create a simple time delay, you can import Darwin and then use sleep(seconds) to do the delay. That only takes whole seconds, though, so for more precise measurements you can import Darwin and use usleep(millionths of a second) for very precise measurement. To test this, I wrote:

import Darwin
print("This is one.")
sleep(1)
print("This is two.")
usleep(400000)
print("This is three.")

Which prints, then waits for 1 sec and prints, then waits for 0.4 sec then prints. All worked as expected.

You are not setting a classpath that includes your compiled class! java can't find any classes if you don't tell it where to look.

java -cp [compiler outpur dir] HelloWorld

Incidentally you do not need to set CLASSPATH the way you have done.

I had the same issue after a reboot, I followed the guide described here

So try the following:

$ sudo -i
# swapoff -a
# exit
$ strace -eopenat kubectl version

After that it works fine.

Write below code in your MainActivity.java file instead of your code.

public class MainActivity extends Activity implements OnClickListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button mBtn1 = (Button) findViewById(R.id.mBtn1);
        mBtn1.setOnClickListener(this);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

    @Override
    public void onClick(View v) {
        Log.i("clicks","You Clicked B1");
        Intent i=new Intent(MainActivity.this, MainActivity2.class);
        startActivity(i);
    }
}

And Declare MainActivity2 into your Androidmanifest.xml file using below code.

<activity
    android:name=".MainActivity2"
    android:label="@string/title_activity_main">
</activity>

I had the same problem and tried everything but it didn't worked. So I used following trick:

function do_stuff(e)
{
    if(e){ alert(e); }
}
$("#delete").click(function() {
    do_stuff("Clicked");
});

You check if that parameter isn't null than you do code. So when the function will triggered second time it will show what you want.

Here is a script which generates grant queries for a particular table. It omits owner's privileges.

SELECT 
    format (
      'GRANT %s ON TABLE %I.%I TO %I%s;',
      string_agg(tg.privilege_type, ', '),
      tg.table_schema,
      tg.table_name,
      tg.grantee,
      CASE
        WHEN tg.is_grantable = 'YES' 
        THEN ' WITH GRANT OPTION' 
        ELSE '' 
      END
    )
  FROM information_schema.role_table_grants tg
  JOIN pg_tables t ON t.schemaname = tg.table_schema AND t.tablename = tg.table_name
  WHERE
    tg.table_schema = 'myschema' AND
    tg.table_name='mytable' AND
    t.tableowner <> tg.grantee
  GROUP BY tg.table_schema, tg.table_name, tg.grantee, tg.is_grantable;

It's better if you check visibility like this: if($('#video-over').is(':visible'))

Quite simply the number is the precision of the timestamp, the fraction of a second held in the column:

SQL> create table t23
  2  (ts0 timestamp(0)
  3   , ts3 timestamp(3)
  4  , ts6 timestamp(6)
  5  )
  6  /

Table created.

SQL> insert into t23 values (systimestamp, systimestamp, systimestamp)
  2  /

1 row created.

If we don't specify a precision then the timestamp defaults to six places.

SQL> alter table t23 add ts_def timestamp;

Table altered.

SQL> update t23

Note that I'm running on Linux so my TIMESTAMP column actually gives me precision to six places i.e. microseconds. This would also be the case on most (all?) flavours of Unix. On Windows the limit is three places i.e. milliseconds. (Is this still true of the most modern flavours of Windows - citation needed).

As might be expected, the documentation covers this. Find out more.

"when you create timestamp(9) this gives you nanos right"

Only if the OS supports it. As you can see, my OEL appliance does not:

SQL> alter table t23 add ts_nano timestamp(9)
  2  /

Table altered.

SQL> update t23 set ts_nano = systimestamp(9)
  2  /

1 row updated.

(Those trailing zeroes could be a coincidence but they aren't.)

You can use /* tslint:disable-next-line */ to locally disable tslint. However, as this is a compiler error disabling tslint might not help.

You can always temporarily cast $ to any:

delete ($ as any).summernote.options.keyMap.pc.TAB

which will allow you to access whatever properties you want.

Edit: As of Typescript 2.6, you can now bypass a compiler error/warning for a specific line:

if (false) {
    // @ts-ignore: Unreachable code error
    console.log("hello");
}

Note that the official docs "recommend you use [this] very sparingly". It is almost always preferable to cast to any instead as that better expresses intent.

the following can be used:

 install.packages("data.table")
 library(data.table)

For large nested hashes this script could be helpful for you. It prints a nested hash in a nice python/like syntax with only indents to make it easy to copy.

module PrettyHash
  # Usage: PrettyHash.call(nested_hash)
  # Prints the nested hash in the easy to look on format
  # Returns the amount of all values in the nested hash

  def self.call(hash, level: 0, indent: 2)
    unique_values_count = 0
    hash.each do |k, v|
      (level * indent).times { print ' ' }
      print "#{k}:"
      if v.is_a?(Hash)
        puts
        unique_values_count += call(v, level: level + 1, indent: indent)
      else
        puts " #{v}"
        unique_values_count += 1
      end
    end
    unique_values_count
  end
end

Example usage:

  h = {a: { b: { c: :d }, e: :f }, g: :i }
  PrettyHash.call(h)

a:
  b:
    c: d
  e: f
g: i
=> 3

The returned value is the count (3) of all the end-level values of the nested hash.

See Python Web Frameworks wiki.

You probably do not need the full stack frameworks, but the remaining list is still quite long.

This can also be the problem if your string is 6/15/2019. DateTime Parse expects it to be 06/15/2019.

So first split it by slash

var dateParts = "6/15/2019"
var month = dateParts[0].PadLeft(2, '0');
var day = dateParts[1].PadLeft(2, '0');
var year = dateParts[2] 


var properFormat = month + "/" +day +"/" + year;

Now you can use DateTime.Parse(properFormat, "MM/dd/yyyy"). It is very strange but this is only thing working for me.

Just another exception to the already posted list. On 32-bit platforms, pointers can take 6, not 4, bytes:

#include <stdio.h>
#include <stdlib.h>

int main() {
    char far* ptr; // note that this is a far pointer
    printf( "%d\n", sizeof( ptr));
    return EXIT_SUCCESS;
}

If you compile this program with Open Watcom and run it, you'll get 6, because far pointers that it supports consist of 32-bit offset and 16-bit segment values

The solution from PSL will not work in Firefox. FF accepts event only as a formal parameter. So you have to find another way to identify the selected row. My solution is something like this:

...
$('#mySelector')
  .on('show.bs.modal', function(e) {
  var mid;


  if (navigator.userAgent.toLowerCase().indexOf('firefox') > -1) 
    mid = $(e.relatedTarget).data('id');
  else
    mid = $(event.target).closest('tr').data('id');

...

Here's a comprehensive yet non-exhaustive list of examples of list operations and whether or not they are thread safe. Hoping to get an answer regarding the obj in a_list language construct here.

To answer to your second question. You can just hit the IP address of the machine that your flask app is running, e.g. 192.168.1.100 in a browser on different machine on the same network and you are there. Though, you will not be able to access it if you are on a different network. Firewalls or VLans can cause you problems with reaching your application. If that computer has a public IP, then you can hit that IP from anywhere on the planet and you will be able to reach the app. Usually this might impose some configuration, since most of the public servers are behind some sort of router or firewall.

I know I'm a little late to the party, but I did want to throw some interjections. (I would have commented but not enough reputation points yet, so, here's a full answer).

This requires the latest version of VS Code, Azure Repo Extention, and Git to be installed.

Anyone looking to use the new VS Code (or using the preview like myself), when you go to the Settings (Still File -> Preferences -> Settings or CTRL+, ) you'll be looking under User Settings -> Extensions -> Azure Repos.

Then under Tfvc: Location you can paste the location of the executable.

For 2017 it'll be

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\TF.exe

Or for 2019 (Preview)

C:\Program Files (x86)\Microsoft Visual Studio\2019\Preview\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\TF.exe

After adding the location, I closed my VS Code (not sure if this was needed) and went my git repo to copy the git URL.

After that, went back into VS Code went to the Command Palette (View -> Command Palette or CTRL+Shift+P) typed Git: Clone pasted my repo:

Selected the location for the repo to be stored. Next was an error that popped up. I proceeded to follow this video which walked me through clicking on the Team button with the exclamation mark on the bottom of your VS Code Screen

Then chose the new method of authentication

Copy by using CTRL+C and then press enter. Your browser will launch a page where you'll enter the code you copied (CTRL+V).

Click Continue

Log in with your Microsoft Credentials and you should see a change on the bottom bar of VS Code.

Cheers!

Also you can use ss utility to dump sockets statistics.

To dump summary:

ss -s

Total: 91 (kernel 0)
TCP:   18 (estab 11, closed 0, orphaned 0, synrecv 0, timewait 0/0), ports 0

Transport Total     IP        IPv6
*         0         -         -

INET      22        18        4        
FRAG      0         0         0

To display all sockets:

ss -a

To display UDP sockets:

ss -u -a

To display TCP sockets:

ss -t -a

Here you can read ss man: ss

To show the full element (if it's possible with the current window size):

var element       = $("#some_element");
var elementHeight = element.height();
var windowHeight  = $(window).height();

var offset = Math.min(elementHeight, windowHeight) + element.offset().top;
$('html, body').animate({ scrollTop: offset }, 500);

The book is a bit dated with respect to subclass-superclass calling. It's also a little dated with respect to subclassing built-in classes.

It looks like this nowadays:

class FileInfo(dict):
    """store file metadata"""
    def __init__(self, filename=None):
        super(FileInfo, self).__init__()
        self["name"] = filename

Note the following:

1. We can directly subclass built-in classes, like dict, list, tuple, etc.

2. The super function handles tracking down this class's superclasses and calling functions in them appropriately.

Try: http://www.mattweber.org/2007/03/04/python-script-renamepy/

I like to have my music, movie, and picture files named a certain way. When I download files from the internet, they usually don’t follow my naming convention. I found myself manually renaming each file to fit my style. This got old realy fast, so I decided to write a program to do it for me.

This program can convert the filename to all lowercase, replace strings in the filename with whatever you want, and trim any number of characters from the front or back of the filename.

The program's source code is also available.

The new cv2 interface for Python integrates numpy arrays into the OpenCV framework, which makes operations much simpler as they are represented with simple multidimensional arrays. For example, your question would be answered with:

import cv2  # Not actually necessary if you just want to create an image.
import numpy as np
blank_image = np.zeros((height,width,3), np.uint8)

This initialises an RGB-image that is just black. Now, for example, if you wanted to set the left half of the image to blue and the right half to green , you could do so easily:

blank_image[:,0:width//2] = (255,0,0)      # (B, G, R)
blank_image[:,width//2:width] = (0,255,0)

If you want to save yourself a lot of trouble in future, as well as having to ask questions such as this one, I would strongly recommend using the cv2 interface rather than the older cv one. I made the change recently and have never looked back. You can read more about cv2 at the OpenCV Change Logs.

Yes you can. Just check my fiddle for clarification. For demo purpose i kept the code in fiddle at same location. You can extract that code as shown in two different Javascript files and load them in html file.

https://jsfiddle.net/mvora/mrLmkxmo/

 /******** PUT THIS CODE IN ONE JS FILE *******/

    var secondFileFuntion = function(){
        this.name = 'XYZ';
    }

    secondFileFuntion.prototype.getSurname = function(){
     return 'ABC';
    }


    var secondFileObject = new secondFileFuntion();

    /******** Till Here *******/

    /******** PUT THIS CODE IN SECOND JS FILE *******/

    function firstFileFunction(){
      var name = secondFileObject.name;
      var surname = secondFileObject.getSurname()
      alert(name);
      alert(surname );
    }

    firstFileFunction();

If you make an object using the constructor function and trying access the property or method from it in second file, it will give you the access of properties which are present in another file.

Just take care of sequence of including these files in index.html

I know this is an old question, but I thought I'd add my two cents anyway:

It depends on what the link is going to do, but usually, I would be pointing the link at a url that could possibly be displaying/doing the same thing, for example, if you're making a little about box pop up:

<a id="about" href="/about">About</a>

Then with jQuery

$('#about').click(function(e) {
    $('#aboutbox').show();
    e.preventDefault();
});

This way, very old browsers (or browsers with JavaScript disabled) can still navigate to a separate about page, but more importantly, Google will also pick this up and crawl the contents of the about page.

You can do:

import matplotlib.pyplot as plt
x = [1,2,3,4,5]
y = [2,1,3,6,7]

plt.plot(x, y, style='.-')
plt.show()

This will return a graph with the data points marked with a dot

There is one more option that I recently discovered that some people may find useful because it allows you to change a CSS rule within a style element - thus avoiding the need for repeated use of an angular directive such as ng-style, ng-class, ng-show, ng-hide, ng-animate, and others.

This option makes use of a service with service variables which are set by a controller and watched by an attribute-directive I call "custom-style". This strategy could be used in many different ways, and I attempted to provide some general guidance with this fiddle.

var app = angular.module('myApp', ['ui.bootstrap']);
app.service('MainService', function(){
    var vm = this;
});
app.controller('MainCtrl', function(MainService){
    var vm = this;
    vm.ms = MainService;
});
app.directive('customStyle', function(MainService){
    return {
        restrict : 'A',
        link : function(scope, element, attr){
            var style = angular.element('<style></style>');
            element.append(style);
            scope.$watch(function(){ return MainService.theme; },
                function(){
                    var css = '';
                    angular.forEach(MainService.theme, function(selector, key){
                        angular.forEach(MainService.theme[key], function(val, k){
                            css += key + ' { '+k+' : '+val+'} ';
                        });                        
                    });
                    style.html(css);
                }, true);
        }
    };
});

Iterator it = map.entrySet().iterator();
while (it.hasNext()) {
     Map.Entry pairs = (Map.Entry)it.next();

     if(pairs.getKey().equals("mango"))
     {
        map.put(pairs.getKey(), pairs.getValue().add(18));
     }

     else if(!map.containsKey("mango"))
     {
        List<Integer> ints = new ArrayList<Integer>();
        ints.add(18);
        map.put("mango",ints);
     }

     it.remove(); // avoids a ConcurrentModificationException
}

EDIT: So inside the while try this:

map.put(pairs.getKey(), pairs.getValue().add(number))

You are getting the error because you are trying to put an integer to the values, whereas it is expected an ArrayList.

EDIT 2: Then put the following inside your while loop:

if(pairs.getKey().equals("mango"))
{
    map.put(pairs.getKey(), pairs.getValue().add(18));
}

else if(!map.containsKey("mango"))
{
     List<Integer> ints = new ArrayList<Integer>();
     ints.add(18);
     map.put("mango",ints);
 }

EDIT 3: By reading your requirements, I come to think you may not need a loop. You may want to only check if the map contains the key mango, and if it does add 18, else create a new entry in the map with key mango and value 18.

So all you may need is the following, without the loop:

if(map.containsKey("mango"))
{
    map.put("mango", map.get("mango).add(18));
}

else
{
    List<Integer> ints = new ArrayList<Integer>();
    ints.add(18);
    map.put("mango", ints);
}

You can get the different values with:

set(Article.objects.values_list('comment_id', flat=True))

By default flush mode is AUTO which means that: "The Session is sometimes flushed before query execution in order to ensure that queries never return stale state", but most of the time session is flushed when you commit your changes. Manual calling of the flush method is usefull when you use FlushMode=MANUAL or you want to do some kind of optimization. But I have never done this so I can't give you practical advice.

As I said in your previous question, there is no need to base64 encode the string, it will only make the program slower. Just use the repr

>>> with open("images/image.gif", "rb") as fin:
...  image_data=fin.read()
...
>>> with open("image.py","wb") as fout:
...  fout.write("image_data="+repr(image_data))
...

Now the image is stored as a variable called image_data in a file called image.py Start a fresh interpreter and import the image_data

>>> from image import image_data
>>>

One issue you might run into is is_home() returns true when a registered query_var is present in the home URL. For example, if http://example.com displays a static page instead of the blog, http://example.com/?c=123 will return the blog.

See https://core.trac.wordpress.org/ticket/25143 and https://wordpress.org/support/topic/adding-query-var-makes-front-page-missing/ for more info on this.

What you can do (if you're not attempting to affect the query) is use add_rewrite_endpoint(). It should be run during the init action as it affects the rewrite rules. Eg.

add_action( 'init', 'add_custom_setcookie_rewrite_endpoints' );

function add_custom_setcookie_rewrite_endpoints() {
    //add ?c=123 endpoint with
    //EP_ALL so endpoint is present across all places
    //no effect on the query vars
    add_rewrite_endpoint( 'c', EP_ALL, $query_vars = false );
}

This should give you access to $_GET['c'] when the url contains more information like www.example.com/news?c=123.

Remember to flush your rewrite rules after adding/modifying this.

I try this with jquery; use this and have fun :D

    jQuery.printInExcel = function (DivID) 
{ 
var ExcelApp = new ActiveXObject("Excel.Application"); 
ExcelApp.Workbooks.Add; 
ExcelApp.visible = true; 
var str = ""; 
var tblcount = 0; 
var trcount = 0;
 $("#" + DivID + " table").each(function () 
{ $(this).find("tr").each(function () 
{ var tdcount = 0; $(this).find("td").each(function () 
{ str = str + $(this).text(); ExcelApp.Cells(trcount + 1, tdcount + 1).Value = str; 
str = ""; tdcount++ 
}); 
trcount++ 
}); tblcount++ 
}); 
};

use this in your class and call it with $.printInExcel(your var);

Reference Resolution is described by RFC 3986 Uniform Resource Identifier (URI): Generic Syntax. And that is exactly how it supposed to work. To preserve base URI path you need to add slash at the end of the base URI and remove slash at the beginning of relative URI.

If base URI contains non-empty path, merge procedure discards it's last part (after last /). Relevant section:

5.2.3. Merge Paths

The pseudocode above refers to a "merge" routine for merging a relative-path reference with the path of the base URI. This is accomplished as follows:

• If the base URI has a defined authority component and an empty path, then return a string consisting of "/" concatenated with the reference's path; otherwise

• return a string consisting of the reference's path component appended to all but the last segment of the base URI's path (i.e., excluding any characters after the right-most "/" in the base URI path, or excluding the entire base URI path if it does not contain any "/" characters).

If relative URI starts with a slash, it is called a absolute-path relative URI. In this case merge procedure ignore all base URI path. For more information check 5.2.2. Transform References section.

Data-Binding

You go around making your webpage, and keep on putting {{data bindings}} whenever you feel you would have dynamic data. Angular will then provide you a $scope handler, which you can populate (statically or through calls to the web server).

This is a good understanding of data-binding. I think you've got that down.

DOM Manipulation

For simple DOM manipulation, which doesnot involve data manipulation (eg: color changes on mousehover, hiding/showing elements on click), jQuery or old-school js is sufficient and cleaner. This assumes that the model in angular's mvc is anything that reflects data on the page, and hence, css properties like color, display/hide, etc changes dont affect the model.

I can see your point here about "simple" DOM manipulation being cleaner, but only rarely and it would have to be really "simple". I think DOM manipulation is one the areas, just like data-binding, where Angular really shines. Understanding this will also help you see how Angular considers its views.

I'll start by comparing the Angular way with a vanilla js approach to DOM manipulation. Traditionally, we think of HTML as not "doing" anything and write it as such. So, inline js, like "onclick", etc are bad practice because they put the "doing" in the context of HTML, which doesn't "do". Angular flips that concept on its head. As you're writing your view, you think of HTML as being able to "do" lots of things. This capability is abstracted away in angular directives, but if they already exist or you have written them, you don't have to consider "how" it is done, you just use the power made available to you in this "augmented" HTML that angular allows you to use. This also means that ALL of your view logic is truly contained in the view, not in your javascript files. Again, the reasoning is that the directives written in your javascript files could be considered to be increasing the capability of HTML, so you let the DOM worry about manipulating itself (so to speak). I'll demonstrate with a simple example.

This is the markup we want to use. I gave it an intuitive name.

<div rotate-on-click="45"></div>

First, I'd just like to comment that if we've given our HTML this functionality via a custom Angular Directive, we're already done. That's a breath of fresh air. More on that in a moment.

Implementation with jQuery

live demo here (click).

function rotate(deg, elem) {
  $(elem).css({
    webkitTransform: 'rotate('+deg+'deg)', 
    mozTransform: 'rotate('+deg+'deg)', 
    msTransform: 'rotate('+deg+'deg)', 
    oTransform: 'rotate('+deg+'deg)', 
    transform: 'rotate('+deg+'deg)'    
  });
}

function addRotateOnClick($elems) {
  $elems.each(function(i, elem) {
    var deg = 0;
    $(elem).click(function() {
      deg+= parseInt($(this).attr('rotate-on-click'), 10);
      rotate(deg, this);
    });
  });
}

addRotateOnClick($('[rotate-on-click]'));

Implementation with Angular

live demo here (click).

app.directive('rotateOnClick', function() {
  return {
    restrict: 'A',
    link: function(scope, element, attrs) {
      var deg = 0;
      element.bind('click', function() {
        deg+= parseInt(attrs.rotateOnClick, 10);
        element.css({
          webkitTransform: 'rotate('+deg+'deg)', 
          mozTransform: 'rotate('+deg+'deg)', 
          msTransform: 'rotate('+deg+'deg)', 
          oTransform: 'rotate('+deg+'deg)', 
          transform: 'rotate('+deg+'deg)'    
        });
      });
    }
  };
});

Pretty light, VERY clean and that's just a simple manipulation! In my opinion, the angular approach wins in all regards, especially how the functionality is abstracted away and the dom manipulation is declared in the DOM. The functionality is hooked onto the element via an html attribute, so there is no need to query the DOM via a selector, and we've got two nice closures - one closure for the directive factory where variables are shared across all usages of the directive, and one closure for each usage of the directive in the link function (or compile function).

Two-way data binding and directives for DOM manipulation are only the start of what makes Angular awesome. Angular promotes all code being modular, reusable, and easily testable and also includes a single-page app routing system. It is important to note that jQuery is a library of commonly needed convenience/cross-browser methods, but Angular is a full featured framework for creating single page apps. The angular script actually includes its own "lite" version of jQuery so that some of the most essential methods are available. Therefore, you could argue that using Angular IS using jQuery (lightly), but Angular provides much more "magic" to help you in the process of creating apps.

This is a great post for more related information: How do I “think in AngularJS” if I have a jQuery background?

General differences.

The above points are aimed at the OP's specific concerns. I'll also give an overview of the other important differences. I suggest doing additional reading about each topic as well.

Angular and jQuery can't reasonably be compared.

Angular is a framework, jQuery is a library. Frameworks have their place and libraries have their place. However, there is no question that a good framework has more power in writing an application than a library. That's exactly the point of a framework. You're welcome to write your code in plain JS, or you can add in a library of common functions, or you can add a framework to drastically reduce the code you need to accomplish most things. Therefore, a more appropriate question is:

Why use a framework?

Good frameworks can help architect your code so that it is modular (therefore reusable), DRY, readable, performant and secure. jQuery is not a framework, so it doesn't help in these regards. We've all seen the typical walls of jQuery spaghetti code. This isn't jQuery's fault - it's the fault of developers that don't know how to architect code. However, if the devs did know how to architect code, they would end up writing some kind of minimal "framework" to provide the foundation (achitecture, etc) I discussed a moment ago, or they would add something in. For example, you might add RequireJS to act as part of your framework for writing good code.

Here are some things that modern frameworks are providing:

• Templating
• Data-binding
• routing (single page app)
• clean, modular, reusable architecture
• security
• additional functions/features for convenience

Before I further discuss Angular, I'd like to point out that Angular isn't the only one of its kind. Durandal, for example, is a framework built on top of jQuery, Knockout, and RequireJS. Again, jQuery cannot, by itself, provide what Knockout, RequireJS, and the whole framework built on top them can. It's just not comparable.

If you need to destroy a planet and you have a Death Star, use the Death star.

Angular (revisited).

Building on my previous points about what frameworks provide, I'd like to commend the way that Angular provides them and try to clarify why this is matter of factually superior to jQuery alone.

DOM reference.

In my above example, it is just absolutely unavoidable that jQuery has to hook onto the DOM in order to provide functionality. That means that the view (html) is concerned about functionality (because it is labeled with some kind of identifier - like "image slider") and JavaScript is concerned about providing that functionality. Angular eliminates that concept via abstraction. Properly written code with Angular means that the view is able to declare its own behavior. If I want to display a clock:

<clock></clock>

Done.

Yes, we need to go to JavaScript to make that mean something, but we're doing this in the opposite way of the jQuery approach. Our Angular directive (which is in it's own little world) has "augumented" the html and the html hooks the functionality into itself.

MVW Architecure / Modules / Dependency Injection

Angular gives you a straightforward way to structure your code. View things belong in the view (html), augmented view functionality belongs in directives, other logic (like ajax calls) and functions belong in services, and the connection of services and logic to the view belongs in controllers. There are some other angular components as well that help deal with configuration and modification of services, etc. Any functionality you create is automatically available anywhere you need it via the Injector subsystem which takes care of Dependency Injection throughout the application. When writing an application (module), I break it up into other reusable modules, each with their own reusable components, and then include them in the bigger project. Once you solve a problem with Angular, you've automatically solved it in a way that is useful and structured for reuse in the future and easily included in the next project. A HUGE bonus to all of this is that your code will be much easier to test.

It isn't easy to make things "work" in Angular.

THANK GOODNESS. The aforementioned jQuery spaghetti code resulted from a dev that made something "work" and then moved on. You can write bad Angular code, but it's much more difficult to do so, because Angular will fight you about it. This means that you have to take advantage (at least somewhat) to the clean architecture it provides. In other words, it's harder to write bad code with Angular, but more convenient to write clean code.

Angular is far from perfect. The web development world is always growing and changing and there are new and better ways being put forth to solve problems. Facebook's React and Flux, for example, have some great advantages over Angular, but come with their own drawbacks. Nothing's perfect, but Angular has been and is still awesome for now. Just as jQuery once helped the web world move forward, so has Angular, and so will many to come.
