@dhanushka's approach showed the most promise but I wanted to play around in Python so went ahead and translated it for fun:

import cv2
import numpy as np
from cv2 import boundingRect, countNonZero, cvtColor, drawContours, findContours, getStructuringElement, imread, morphologyEx, pyrDown, rectangle, threshold

large = imread(image_path)
# downsample and use it for processing
rgb = pyrDown(large)
# apply grayscale
small = cvtColor(rgb, cv2.COLOR_BGR2GRAY)
# morphological gradient
morph_kernel = getStructuringElement(cv2.MORPH_ELLIPSE, (3, 3))
grad = morphologyEx(small, cv2.MORPH_GRADIENT, morph_kernel)
# binarize
_, bw = threshold(src=grad, thresh=0, maxval=255, type=cv2.THRESH_BINARY+cv2.THRESH_OTSU)
morph_kernel = getStructuringElement(cv2.MORPH_RECT, (9, 1))
# connect horizontally oriented regions
connected = morphologyEx(bw, cv2.MORPH_CLOSE, morph_kernel)
mask = np.zeros(bw.shape, np.uint8)
# find contours
im2, contours, hierarchy = findContours(connected, cv2.RETR_CCOMP, cv2.CHAIN_APPROX_SIMPLE)
# filter contours
for idx in range(0, len(hierarchy[0])):
    rect = x, y, rect_width, rect_height = boundingRect(contours[idx])
    # fill the contour
    mask = drawContours(mask, contours, idx, (255, 255, 2555), cv2.FILLED)
    # ratio of non-zero pixels in the filled region
    r = float(countNonZero(mask)) / (rect_width * rect_height)
    if r > 0.45 and rect_height > 8 and rect_width > 8:
        rgb = rectangle(rgb, (x, y+rect_height), (x+rect_width, y), (0,255,0),3)

Now to display the image:

from PIL import Image
Image.fromarray(rgb).show()

Not the most Pythonic of scripts but I tried to resemble the original C++ code as closely as possible for readers to follow.

It works almost as well as the original. I'll be happy to read suggestions how it could be improved/fixed to resemble the original results fully.

If you want to switch the jdk on a regular basis (or update to a new one once it is released), it's very conveniant to use sdkman.

You can additional tools like maven with sdkman, too.

This gives you just the revision.

git rev-parse HEAD

Use the after method on the Tk object:

from tkinter import *

root = Tk()

def task():
    print("hello")
    root.after(2000, task)  # reschedule event in 2 seconds

root.after(2000, task)
root.mainloop()

Here's the declaration and documentation for the after method:

def after(self, ms, func=None, *args):
    """Call function once after given time.

    MS specifies the time in milliseconds. FUNC gives the
    function which shall be called. Additional parameters
    are given as parameters to the function call.  Return
    identifier to cancel scheduling with after_cancel."""

The problem lies in:

$query = $this->db->conn->prepare('SELECT value, param FROM ws_settings WHERE name = ?');
$query->bind_param('s', $setting);

The prepare() method can return false and you should check for that. As for why it returns false, perhaps the table name or column names (in SELECT or WHERE clause) are not correct?

Also, consider use of something like $this->db->conn->error_list to examine errors that occurred parsing the SQL. (I'll occasionally echo the actual SQL statement strings and paste into phpMyAdmin to test, too, but there's definitely something failing there.)

I know the question has been asked a long time ago, but I am surprised that nobody has given the most straightforward unix answer:

split -l 5000 -d --additional-suffix=.txt $FileName file

• -l 5000: split file into files of 5,000 lines each.
• -d: numerical suffix. This will make the suffix go from 00 to 99 by default instead of aa to zz.
• --additional-suffix: lets you specify the suffix, here the extension
• $FileName: name of the file to be split.
• file: prefix to add to the resulting files.

As always, check out man split for more details.

For Mac, the default version of split is apparently dumbed down. You can install the GNU version using the following command. (see this question for more GNU utils)

brew install coreutils

and then you can run the above command by replacing split with gsplit. Check out man gsplit for details.

Here's A generic VBA Array To Range function that writes an array to the sheet in a single 'hit' to the sheet. This is much faster than writing the data into the sheet one cell at a time in loops for the rows and columns... However, there's some housekeeping to do, as you must specify the size of the target range correctly.

This 'housekeeping' looks like a lot of work and it's probably rather slow: but this is 'last mile' code to write to the sheet, and everything is faster than writing to the worksheet. Or at least, so much faster that it's effectively instantaneous, compared with a read or write to the worksheet, even in VBA, and you should do everything you possibly can in code before you hit the sheet.

A major component of this is error-trapping that I used to see turning up everywhere . I hate repetitive coding: I've coded it all here, and - hopefully - you'll never have to write it again.

A VBA 'Array to Range' function

Public Sub ArrayToRange(rngTarget As Excel.Range, InputArray As Variant)
' Write an array to an Excel range in a single 'hit' to the sheet
' InputArray must be a 2-Dimensional structure of the form Variant(Rows, Columns)

' The target range is resized automatically to the dimensions of the array, with
' the top left cell used as the start point.

' This subroutine saves repetitive coding for a common VBA and Excel task.

' If you think you won't need the code that works around common errors (long strings
' and objects in the array, etc) then feel free to comment them out.

You will need the source for ArrayDimensions:

This API declaration is required in the module header:

Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" _
                   (Destination As Any, _
                    Source As Any, _
                    ByVal Length As Long)

...And here's the function itself:

Private Function ArrayDimensions(arr As Variant) As Integer
  '-----------------------------------------------------------------
  ' will return:
  ' -1 if not an array
  ' 0  if an un-dimmed array
  ' 1  or more indicating the number of dimensions of a dimmed array
  '-----------------------------------------------------------------

    ArrayDimensions = -1
    Exit Function
  End If

  'get the address of the SAFEARRAY descriptor
  'this is stored in the second half of the

  CopyMemory ptr, ByVal VarPtr(arr) + 8, 4

  'see whether the routine was passed a Variant
  'that contains an array, rather than directly an array
  'in the former case ptr already points to the SA structure.
  'Thanks to Monte Hansen for this fix

  If (vType And VT_BYREF) Then
    ' ptr is a pointer to a pointer
    CopyMemory ptr, ByVal ptr, 4
  End If

  'get the address of the SAFEARRAY structure
  'this is stored in the descriptor

  'get the first word of the SAFEARRAY structure
  'which holds the number of dimensions
  '...but first check that saAddr is non-zero, otherwise
  'this routine bombs when the array is uninitialized

  If ptr Then
    CopyMemory ArrayDimensions, ByVal ptr, 2
  End If

End Function

Also: I would advise you to keep that declaration private. If you must make it a public Sub in another module, insert the Option Private Module statement in the module header. You really don't want your users calling any function with CopyMemoryoperations and pointer arithmetic.

Well presumably it's not using the same version of Java when running it externally. Look through the startup scripts carefully to find where it picks up the version of Java to run. You should also check the startup logs to see whether they indicate which version is running.

Alternatively, unless you need the Java 7 features, you could always change your compiler preferences in Eclipse to target 1.6 instead.

I could get result by using following:

$resu = mysqli_fetch_assoc(mysqli_query($conn, "SELECT * FROM employees1 WHERE pkint =58"));
echo ( "<br />". $resu['pkint']). "<br />" . $resu['f1'] . "<br />" . $resu['f2']. "<br />" . $resu['f3']. "<br />" . $resu['f4' ];

employees 1 is table name. pkint is primary key id. f1,f2,f3,f4 are field names. $resu is the variable shortcut for result. Following is the output:

<br />58
<br />Caroline
<br />Smith
<br />Zandu Balm

Volatile Variables are light-weight synchronization. When visibility of latest data among all threads is requirement and atomicity can be compromised , in such situations Volatile Variables must be preferred. Read on volatile variables always return most recent write done by any thread since they are neither cached in registers nor in caches where other processors can not see. Volatile is Lock-Free. I use volatile, when scenario meets criteria as mentioned above.

$img_file='http://www.somedomain.com/someimage.jpg'

$img_file=file_get_contents($img_file);

$file_loc=$_SERVER['DOCUMENT_ROOT'].'/some_dir/test.jpg';

$file_handler=fopen($file_loc,'w');

if(fwrite($file_handler,$img_file)==false){
    echo 'error';
}

fclose($file_handler);

You can add a CSS class of cancel to a submit button to suppress the validation

e.g

<input class="cancel" type="submit" value="Save" />

See the jQuery Validator documentation of this feature here: Skipping validation on submit

EDIT:

The above technique has been deprecated and replaced with the formnovalidate attribute.

<input formnovalidate="formnovalidate" type="submit" value="Save" />

On one of my sites I had to make a custom search by a lot of data some of it from custom fields here is how my $args look like for one of the options:

$args = array(
    'meta_query' => $meta_query,
    'tax_query' => array(
        $query_tax
    ),
    'posts_per_page' => 10,
    'post_type' => 'ad_listing',
    'orderby' => $orderby,
    'order' => $order,
    'paged' => $paged
);

where "$meta_query" is:

$key = "your_custom_key"; //custom_color for example
$value = "blue";//or red or any color
$query_color = array('key' => $key, 'value' => $value);
$meta_query[] = $query_color;

and after that:

query_posts($args);

so you would probably get more info here: http://codex.wordpress.org/Class_Reference/WP_Query and you can search for "meta_query" in the page to get to the info

declare
  x number;
begin
  x := myfunc(myargs);
end;

Alternatively:

select myfunc(myargs) from dual;

The by far the simplest approach is:

yourdf.drop(['columnheading1', 'columnheading2'], axis=1, inplace=True)

Even though the ID selector is the simplest, you can also use the name selector as below:

$('[name='submitted[first_name]']').removeAttr('required');

For more see: https://api.jquery.com/attribute-equals-selector/

Python 2

for x in xrange(1,11):
    print x,

Python 3

for x in range(1,11):
    print(x, end=" ") 

A web app can request access to a sandboxed file system by calling window.requestFileSystem(). Works in Chrome.

window.requestFileSystem = window.requestFileSystem || window.webkitRequestFileSystem;
var fs = null;

window.requestFileSystem(window.TEMPORARY, 1024 * 1024, function (filesystem) {
    fs = filesystem;
}, errorHandler);

fs.root.getFile('Hello.txt', {
    create: true
}, null, errorHandler);

function errorHandler(e) {
  var msg = '';

  switch (e.code) {
    case FileError.QUOTA_EXCEEDED_ERR:
      msg = 'QUOTA_EXCEEDED_ERR';
      break;
    case FileError.NOT_FOUND_ERR:
      msg = 'NOT_FOUND_ERR';
      break;
    case FileError.SECURITY_ERR:
      msg = 'SECURITY_ERR';
      break;
    case FileError.INVALID_MODIFICATION_ERR:
      msg = 'INVALID_MODIFICATION_ERR';
      break;
    case FileError.INVALID_STATE_ERR:
      msg = 'INVALID_STATE_ERR';
      break;
    default:
      msg = 'Unknown Error';
      break;
  };

  console.log('Error: ' + msg);
}

By running the above command you can see what are all the jobs running.

kill -9 <PID Number>

Enter the PID (process identification number), so this will terminate/kill the instance.

Comment out the res.render lines in your code and add in next(err); instead. If you're not using a view engine, the res.render stuff will throw an error.

Sorry, you'll have to comment out this line as well:

app.set('view engine', 'html');

My solution would result in not using a view engine though. You don't need a view engine, but if that's the goal, try this:

app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
//swap jade for ejs etc

You'll need the res.render lines when using a view engine as well. Something like this:

// error handlers
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
  app.use(function(err, req, res, next) {
    res.status(err.status || 500);
    res.render('error', {
    message: err.message,
    error: err
    });
  });
}
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
  res.status(err.status || 500);
  next(err);
  res.render('error', {
  message: err.message,
  error: {}
  });
});

The answer is simply that it makes no difference how the segue is triggered.

The prepareForSegue:sender: method is called in any case and this is where you pass your parameters across.

It is better to use ./manage.py sqlflush | ./manage.py dbshell because sqlclear requires app to flush.

WARNING! THIS WILL DELETE THE ENTIRE GIT HISTORY FOR YOUR SUBMODULE. ONLY DO THIS IF YOU CREATED THE SUBMODULE BY ACCIDENT. CERTAINLY NOT WHAT YOU WANT TO DO IN MOST CASES.

In my situation, there was a sub-directory which had a .git directory.

What I do is simply remove that .git directory from my sub-directory.

You're looking for implode()

$string = implode(",", $array);

sub domain is part of the domain, it's like subletting a room of an apartment. A records has to be setup on the dns for the domain e.g

mydomain.com has IP 123.456.789.999 and hosted with Godaddy. Now to get the sub domain

anothersite.mydomain.com

of which the site is actually on another server then

login to Godaddy and add an A record ^dnsimple anothersite.mydomain.com and point the IP to the other server 98.22.11.11

And that's it.

I found a solution to my problem, by using the visble-command.

You may try using ellipsis by adding the following in CSS:

.truncate {
  width: 250px;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

But it seems like this code just applies to one-line trim. More ways to trim text and show ellipsis can be found in this website: http://blog.sanuker.com/?p=631

The most important part is the concepts. Once you understand how the building blocks work, differences in syntax amount to little more than mild dialects. A layer on top of your regular expression engine's syntax is the syntax of the programming language you're using. Languages such as Perl remove most of this complication, but you'll have to keep in mind other considerations if you're using regular expressions in a C program.

If you think of regular expressions as building blocks that you can mix and match as you please, it helps you learn how to write and debug your own patterns but also how to understand patterns written by others.

Start simple

Conceptually, the simplest regular expressions are literal characters. The pattern N matches the character 'N'.

Regular expressions next to each other match sequences. For example, the pattern Nick matches the sequence 'N' followed by 'i' followed by 'c' followed by 'k'.

If you've ever used grep on Unix—even if only to search for ordinary looking strings—you've already been using regular expressions! (The re in grep refers to regular expressions.)

Order from the menu

Adding just a little complexity, you can match either 'Nick' or 'nick' with the pattern [Nn]ick. The part in square brackets is a character class, which means it matches exactly one of the enclosed characters. You can also use ranges in character classes, so [a-c] matches either 'a' or 'b' or 'c'.

The pattern . is special: rather than matching a literal dot only, it matches any character^†. It's the same conceptually as the really big character class [-.?+%$A-Za-z0-9...].

Think of character classes as menus: pick just one.

Helpful shortcuts

Using . can save you lots of typing, and there are other shortcuts for common patterns. Say you want to match a digit: one way to write that is [0-9]. Digits are a frequent match target, so you could instead use the shortcut \d. Others are \s (whitespace) and \w (word characters: alphanumerics or underscore).

The uppercased variants are their complements, so \S matches any non-whitespace character, for example.

Once is not enough

From there, you can repeat parts of your pattern with quantifiers. For example, the pattern ab?c matches 'abc' or 'ac' because the ? quantifier makes the subpattern it modifies optional. Other quantifiers are

• * (zero or more times)
• + (one or more times)
• {n} (exactly n times)
• {n,} (at least n times)
• {n,m} (at least n times but no more than m times)

Putting some of these blocks together, the pattern [Nn]*ick matches all of

• ick
• Nick
• nick
• Nnick
• nNick
• nnick
• (and so on)

The first match demonstrates an important lesson: * always succeeds! Any pattern can match zero times.

A few other useful examples:

• [0-9]+ (and its equivalent \d+) matches any non-negative integer
• \d{4}-\d{2}-\d{2} matches dates formatted like 2019-01-01

Grouping

A quantifier modifies the pattern to its immediate left. You might expect 0abc+0 to match '0abc0', '0abcabc0', and so forth, but the pattern immediately to the left of the plus quantifier is c. This means 0abc+0 matches '0abc0', '0abcc0', '0abccc0', and so on.

To match one or more sequences of 'abc' with zeros on the ends, use 0(abc)+0. The parentheses denote a subpattern that can be quantified as a unit. It's also common for regular expression engines to save or "capture" the portion of the input text that matches a parenthesized group. Extracting bits this way is much more flexible and less error-prone than counting indices and substr.

Alternation

Earlier, we saw one way to match either 'Nick' or 'nick'. Another is with alternation as in Nick|nick. Remember that alternation includes everything to its left and everything to its right. Use grouping parentheses to limit the scope of |, e.g., (Nick|nick).

For another example, you could equivalently write [a-c] as a|b|c, but this is likely to be suboptimal because many implementations assume alternatives will have lengths greater than 1.

Escaping

Although some characters match themselves, others have special meanings. The pattern \d+ doesn't match backslash followed by lowercase D followed by a plus sign: to get that, we'd use \\d\+. A backslash removes the special meaning from the following character.

Greediness

Regular expression quantifiers are greedy. This means they match as much text as they possibly can while allowing the entire pattern to match successfully.

For example, say the input is

"Hello," she said, "How are you?"

You might expect ".+" to match only 'Hello,' and will then be surprised when you see that it matched from 'Hello' all the way through 'you?'.

To switch from greedy to what you might think of as cautious, add an extra ? to the quantifier. Now you understand how \((.+?)\), the example from your question works. It matches the sequence of a literal left-parenthesis, followed by one or more characters, and terminated by a right-parenthesis.

If your input is '(123) (456)', then the first capture will be '123'. Non-greedy quantifiers want to allow the rest of the pattern to start matching as soon as possible.

(As to your confusion, I don't know of any regular-expression dialect where ((.+?)) would do the same thing. I suspect something got lost in transmission somewhere along the way.)

Anchors

Use the special pattern ^ to match only at the beginning of your input and $ to match only at the end. Making "bookends" with your patterns where you say, "I know what's at the front and back, but give me everything between" is a useful technique.

Say you want to match comments of the form

-- This is a comment --

you'd write ^--\s+(.+)\s+--$.

Build your own

Regular expressions are recursive, so now that you understand these basic rules, you can combine them however you like.

Footnote

†: The statement above that . matches any character is a simplification for pedagogical purposes that is not strictly true. Dot matches any character except newline, "\n", but in practice you rarely expect a pattern such as .+ to cross a newline boundary. Perl regexes have a /s switch and Java Pattern.DOTALL, for example, to make . match any character at all. For languages that don't have such a feature, you can use something like [\s\S] to match "any whitespace or any non-whitespace", in other words anything.

You will need to configure you IIS (assuming this is the web server your are/will using) allowing access from WLAN/LAN to specific users (or anonymous). Allow IIS trought your firewall if you have one.

Your application won't need to be changed, that's just networking problems ans configuration you will have to face to allow acces only trought LAN and WLAN.

You should use the provider available in your machine.

1. Goto Control Panel
2. Goto Administrator Tools
3. Goto Data Sources (ODBC)
4. Click the "Drivers" tab.
5. Do you see something called "SQL Server Native Client"?

See the attached screen shot. Here my provider will be SQLNCLI11.0

First create a table in the database with same numbers of columns that are in the csv file.

Then use following query

LOAD DATA INFILE 'D:/Projects/testImport.csv' INTO TABLE cardinfo
FIELDS TERMINATED BY ',' ENCLOSED BY '"'
LINES TERMINATED BY '\r\n'

The easiest option is to make use of the Excel copy/paste.

Public Sub insertRowBelow()
ActiveCell.Offset(1).EntireRow.Insert Shift:=xlDown, CopyOrigin:=xlFormatFromRightOrAbove
ActiveCell.EntireRow.Copy
ActiveCell.Offset(1).EntireRow.PasteSpecial xlPasteFormats
Application.CutCopyMode = False
End Sub

I was missing somehow more dynamic array of strings, where amount of strings could be varied depending on run-time selection, but otherwise strings should be fixed.

I've ended up of coding code snippet like this:

#define INIT_STRING_ARRAY(...)          \
    {                                   \
        char* args[] = __VA_ARGS__;     \
        ev = args;                      \
        count = _countof(args);         \
    }

void InitEnumIfAny(String& key, CMFCPropertyGridProperty* item)
{
    USES_CONVERSION;
    char** ev = nullptr;
    int count = 0;

    if( key.Compare("horizontal_alignment") )
        INIT_STRING_ARRAY( { "top", "bottom" } )

    if (key.Compare("boolean"))
        INIT_STRING_ARRAY( { "yes", "no" } )

    if( ev == nullptr )
        return;

    for( int i = 0; i < count; i++)
        item->AddOption(A2T(ev[i]));

    item->AllowEdit(FALSE);
}

char** ev picks up pointer to array strings, and count picks up amount of strings using _countof function. (Similar to sizeof(arr) / sizeof(arr[0])).

And there is extra Ansi to unicode conversion using A2T macro, but that might be optional for your case.

The following code is working fine. Run the code snippet what it does.

Another option may be to store long strings in an external file and read the file into a string.

To insert a VARCHAR2 into a BLOB column you can rely on the function utl_raw.cast_to_raw as next:

insert into mytable(id, myblob) values (1, utl_raw.cast_to_raw('some magic here'));

It will cast your input VARCHAR2 into RAW datatype without modifying its content, then it will insert the result into your BLOB column.

More details about the function utl_raw.cast_to_raw

The fetch that you are doing should get all the remote branches, but it won't create local branches for them. If you use gitk, you should see the remote branches described as "remotes/origin/dev" or something similar.

To create a local branch based on a remote branch, do something like:

git checkout -b dev refs/remotes/origin/dev

Which should return something like:

Branch dev set up to track remote branch refs/remotes/origin/dev.
Switched to a new branch "dev"

Now, when you are on the dev branch, "git pull" will update your local dev to the same point as the remote dev branch. Note that it will fetch all branches, but only pull the one you are on to the top of the tree.

The issue was solved by dropping those SPs, dropping the user, recreating the user linked to login, and recreating the SPs.

Possibly it got in this state from restoring from backup (during a time when the related login didn't exist) or bulk schema syncing (if its possible to create an SP with execute as even though the user doesn't exist. Could also have been related to this answer.

With CMake it would just be

add_compile_definitions(_USE_MATH_DEFINES)

in CMakeLists.txt.

Define the variables at the beginning of the function so if there are no records, the variables exist and you won't get the error. Check for null values in the returned array.

$hn = null;
$pid = null;
$datereg = null;
$prefix = null;
$fname = null;
$lname = null;
$age = null;
$sex = null;

I got over this issue by using git merge command with the --no-commit option and then explicitly removed the staged file and ignore the changes to the file. E.g.: say I want to ignore any changes to myfile.txt I proceed as follows:

git merge --no-ff --no-commit <merge-branch>
git reset HEAD myfile.txt
git checkout -- myfile.txt
git commit -m "merged <merge-branch>"

You can put statements 2 & 3 in a for loop, if you have a list of files to skip.

Yes, the Map interface will allow you to store Arrays as values. Here's a very simple example:

int[] val = {1, 2, 3};
Map<String, int[]> map = new HashMap<String, int[]>();
map.put("KEY1", val);

Also, depending on your use case you may want to look at the Multimap support offered by guava.

At a minimum, change this:

function BlockID() {
    var IDs = new Array();
        images['s'] = "Images/Block_01.png";
        images['g'] = "Images/Block_02.png";
        images['C'] = "Images/Block_03.png";
        images['d'] = "Images/Block_04.png";
    return IDs;
}

To this:

function BlockID() {
    var IDs = new Object();
        IDs['s'] = "Images/Block_01.png";
        IDs['g'] = "Images/Block_02.png";
        IDs['C'] = "Images/Block_03.png";
        IDs['d'] = "Images/Block_04.png";
    return IDs;
}

There are a couple fixes to point out. First, images is not defined in your original function, so assigning property values to it will throw an error. We correct that by changing images to IDs. Second, you want to return an Object, not an Array. An object can be assigned property values akin to an associative array or hash -- an array cannot. So we change the declaration of var IDs = new Array(); to var IDs = new Object();.

After those changes your code will run fine, but it can be simplified further. You can use shorthand notation (i.e., object literal property value shorthand) to create the object and return it immediately:

function BlockID() {
    return {
            "s":"Images/Block_01.png"
            ,"g":"Images/Block_02.png"
            ,"C":"Images/Block_03.png"
            ,"d":"Images/Block_04.png"
    };
}

DECLARE @StartDate DATETIME, @EndDate DATETIME
SET @StartDate = dateadd(mm, -1, getdate())
SET @StartDate = dateadd(dd, datepart(dd, getdate())*-1, @StartDate)
SET @EndDate = dateadd(mm, 1, @StartDate)
set @StartDate = DATEADD(dd, 1 , @StartDate)

IMPORTANT: It seems like a small difference but you should really use a data attribute to hold the original number to count up to. Altering the original number can have un-intended consequences. For instance, I'm having this animation run everytime an element enters the screen. But if the element enters, exits, and then enters the screen a second time before the first animation finishes, it will count up to the wrong number.

HTML:

<p class="count" data-value="200" >200</p>
<p class="count" data-value="70" >70</p>
<p class="count" data-value="32" >32</p>

JQuery:

$('.count').each(function () {
    $(this).prop('Counter', 0).animate({
            Counter: $(this).data('value')
        }, {
        duration: 1000,
        easing: 'swing',
        step: function (now) {                      
            $(this).text(this.Counter.toFixed(2));
        }
    });
});

If you would like to handle multiple inputs with one handler take a look at my approach where I'm using computed property to get value of the input based on it's name.

import React, { useState } from "react";
import "./style.css";

export default function App() {
  const [state, setState] = useState({
    name: "John Doe",
    email: "[email protected]"
  });

  const handleChange = e => {
    setState({
      [e.target.name]: e.target.value
    });
  };

  return (
    <div>
      <input
        type="text"
        className="name"
        name="name"
        value={state.name}
        onChange={handleChange}
      />

      <input
        type="text"
        className="email"
        name="email"
        value={state.email}
        onChange={handleChange}
      />
    </div>
  );
}

The problem with MVC is that even for "experts" it eats up a lot of valuable time and requires lot of effort. Businesses are driven by the basic thing "Quick Solution that works" regardless of technology behind it. WebForms is a RAD technology that saves time and money. Anything that requires more time is not acceptable by businesses.

Just an addition to the previous answers. Let's not forget that when dealing with real data there might be null values, so it's useful to also include those in the counting by using the option dropna=False (default is True)

An example:

>>> df['Embarked'].value_counts(dropna=False)
S      644
C      168
Q       77
NaN      2

Thanks to 0A0D for a great answer. I've had good luck with it. Darin Dimitrov also makes a good argument about limiting the complexity of your JS files. Still, I do find occasions where collapsing functions to their definitions makes browsing through a file much easier.

Regarding #region in general, this SO Question covers it quite well.

I have made a few modifications to the Macro to support more advanced code collapse. This method allows you to put a description after the //#region keyword ala C# and shows it in the code as shown:

Example code:

//#region InputHandler
var InputHandler = {
    inputMode: 'simple', //simple or advanced

    //#region filterKeys
    filterKeys: function(e) {
        var doSomething = true;
        if (doSomething) {
            alert('something');
        }
    },
    //#endregion filterKeys

    //#region handleInput
    handleInput: function(input, specialKeys) {
        //blah blah blah
    }
    //#endregion handleInput

};
//#endregion InputHandler

If the leading asterisk is a problem, I pipe the git branch as follows

git branch | awk -F ' +' '! /\(no branch\)/ {print $2}'

This also eliminates the '(no branch)' line that shows up when you have detached head.

There are several good answers on here but I wanted to add one since it may be helpful for users like me who have Tomcat installed as a service on a Windows machine.

Option 3 here: http://www.codejava.net/servers/tomcat/4-ways-to-change-jre-for-tomcat

Basically, open tomcatw.exe and point Tomcat to the version of the JVM you need to use then restart the service. Ensure your deployed applications still work as well.

These links explain it with examples

http://dotnetperls.com/openfiledialog

http://www.geekpedia.com/tutorial67_Using-OpenFileDialog-to-open-files.html

private void button1_Click(object sender, EventArgs e)
{
    int size = -1;
    DialogResult result = openFileDialog1.ShowDialog(); // Show the dialog.
    if (result == DialogResult.OK) // Test result.
    {
       string file = openFileDialog1.FileName;
       try
       {
          string text = File.ReadAllText(file);
          size = text.Length;
       }
       catch (IOException)
       {
       }
    }
    Console.WriteLine(size); // <-- Shows file size in debugging mode.
    Console.WriteLine(result); // <-- For debugging use.
}

First convert this structure to a "dictionary" object:

dict = {}
json.forEach(function(x) {
    dict[x.code] = x.name
})

and then simply

countryName = dict[countryCode]

For a list of countries this doesn't matter much, but for larger lists this method guarantees the instant lookup, while the naive searching will depend on the list size.

A container's logs can be found in :

/var/lib/docker/containers/<container id>/<container id>-json.log

(if you use the default log format which is json)

Any problems with the following way of doing it?

int CharToInt(const char c)
{
    switch (c)
    {
    case '0':
        return 0;
    case '1':
        return 1;
    case '2':
        return 2;
    case '3':
        return 3;
    case '4':
        return 4;
    case '5':
        return 5;
    case '6':
        return 6;
    case '7':
        return 7;
    case '8':
        return 8;
    case '9':
        return 9;
    default:
        return 0;
    }
}

I want to serialize objects to strings, and back.

Different from the other answers, but the most straightforward way to do exactly that for most object types is XmlSerializer:

        Subject subject = new Subject();
        XmlSerializer serializer = new XmlSerializer(typeof(Subject));
        using (Stream stream = new MemoryStream())
        {
            serializer.Serialize(stream, subject);
            // do something with stream
            Subject subject2 = (Subject)serializer.Deserialize(stream);
            // do something with subject2
        }

All your public properties of supported types will be serialized. Even some collection structures are supported, and will tunnel down to sub-object properties. You can control how the serialization works with attributes on your properties.

This does not work with all object types, some data types are not supported for serialization, but overall it is pretty powerful, and you don't have to worry about encoding.

Your @POST method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:

@XmlRootElement
public class MyJaxBean {
    @XmlElement public String param1;
    @XmlElement public String param2;
}

Then your @POST method would look like the following:

@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
    System.out.println("param1 = " + input.param1);
    System.out.println("param2 = " + input.param2);
}

This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input in this case. The actual message would look something like:

POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com

{"param1":"hello","param2":"world"}

Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.

HTML <FORM>

The parameters would be annotated using @FormParam:

@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
                   @FormParam("param2") String param2) {
    ...
}

The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:

POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25

param1=hello&param2=world

The content is URL encoded in this case.

If you do not know the names of the FormParam's you can do the following:

@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
    ...
}

HTTP Headers

You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:

@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
                   @HeaderParam("param2") String param2) {
    ...
}

Here's what the HTTP message would look like. Note that this POST does not have a body.

POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world

I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.

HTTP Query Parameters

This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.

@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
                   @QueryParam("param2") String param2) {
    ...
}

Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:

POST /create?param1=hello&param2=world HTTP/1.1
Content-Length: 0
Host: www.example.com

You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.

HTTP Path Parameters

Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:

@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
                   @PathParam("param2") String param2) {
    ...
}

The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.

POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com

This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.

As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM-based HTML pages, then use @FormParam. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.

Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.

Steps to start a certain local MongoDB instance and to connect to in from NodeJS app:

1. Create mongod.cfg for a new database using the path C:\Program Files\MongoDB\Server\4.0\mongod.cfg with the content

   systemLog:
     destination: file
     path: C:\Program Files\MongoDB\Server\4.0\log\mongod.log
   storage:
     dbPath: C:\Program Files\MongoDB\Server\4.0\data\db
   

2. Install mongoDB database by running

   mongod.exe --config "C:\Program Files\MongoDB\Server\4.0\mongod.cfg" --install

3. Run a particular mongoDB database

   mongod.exe --config "C:\Program Files\MongoDB\Server\4.0\mongod.cfg"

4. Run mongoDB service

   mongo 127.0.0.1:27017/db
   

   and !see mongoDB actual connection string to coonect to the service from NodeJS app

   MongoDB shell version v4.0.9
   connecting to: mongodb://127.0.0.1:27017/db?gssapiServiceName=mongodb
   Implicit session: session { "id" : UUID("c7ed5ab4-c64e-4bb8-aad0-ab4736406c03") }
   MongoDB server version: 4.0.9
   Server has startup warnings:
   ...
   

A better, more modern, answer to this question is to use the %pip magic, like:

%pip install scipy

That will automatically use the correct Python version. Using !pip might be tied to a different version of Python, and then you might not find the package after installing it.

And in colab, the magic gives a nice message and button if it detects that you need to restart the runtime if pip updated a packaging you have already imported.

BTW, there is also a %conda magic for doing the same with conda.

I have some experiments about regex in django url, which required from negative to positive numbers

^(?P<pid>(\-\d+|\d+))$

Let's we focused on this (\-\d+|\d+) part and ignoring others, this semicolon | means OR in regex, then the negative value will match with this \-\d+ part, and positive value into this \d+

Simple source will help you. For Ex.

#!/bin/bash
echo "My shell_1"
source my_script1.sh
echo "Back in shell_1"

This work for me in Angular 9:

  import {GoogleMap, GoogleMapsModule} from "@angular/google-maps";
  @ViewChild('Map') Map: GoogleMap; /* Element Map */

  locations = [
   { lat: 7.423568, lng: 80.462287 },
   { lat: 7.532321, lng: 81.021187 },
   { lat: 6.117010, lng: 80.126269 }
  ];

  constructor() {
   var bounds = new google.maps.LatLngBounds();
    setTimeout(() => {
     for (let u in this.locations) {
      var marker = new google.maps.Marker({
       position: new google.maps.LatLng(this.locations[u].lat, 
       this.locations[u].lng),
      });
      bounds.extend(marker.getPosition());
     }

     this.Map.fitBounds(bounds)
    }, 200)
  }

And it automatically centers the map according to the indicated positions.

Result:

You could use sp_executesql instead of exec. That allows you to specify an output parameter.

declare @out_var varchar(max);
execute sp_executesql 
    N'select @out_var = ''hello world''', 
    N'@out_var varchar(max) OUTPUT', 
    @out_var = @out_var output;
select @out_var;

This prints "hello world".

You are selecting inputs with name attribute of "bla", but your inputs have "bla[]" name attribute.

$("input[name='bla[]']").each(function (index, obj) {
        // loop all checked items
    });

Just use join():

# assuming @array is your array:
print join(", ", @array);

I know this is an old question, but it hasn't been correctly addressed, so I'm answering it for others who may run into this problem.

By default Oracle's ODP.net binds variables by position, and treats each position as a new variable.

Treating each copy as a different variable and setting it's value multiple times is a workaround and a pain, as furman87 mentioned, and could lead to bugs, if you are trying to rewrite the query and move things around.

The correct way is to set the BindByName property of OracleCommand to true as below:

var cmd = new OracleCommand(cmdtxt, conn);
cmd.BindByName = true;

You could also create a new class to encapsulate OracleCommand setting the BindByName to true on instantiation, so you don't have to set the value each time. This is discussed in this post

I'm the creator of the key, but the key was attached to an expired Certificate.

To solve it I went to -> Xcode/Preferences/Accounts/"Account you use to archive"/Manage Certificates..

Then click on the dropdown menu with the "+" sign on the bottom left corner, and choose the type of certificate you need updated (mine was Apple Distribution).

This updated my new certificate with its key attached.

If it weren't a homework, you could use existing methods such as Character.isDigit(char), Character.isUpperCase(char) and Character.isLowerCase(char) which are a bit "smarter", because they don't operate only in ASCII, but also in various charsets.

static final char[] VOWELS = { 'a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U' };

static boolean isVowel(char ch) {
    for (char vowel : VOWELS) {
        if (vowel == ch) {
            return true;
        }
    }
    return false;
}

static boolean isDigit(char ch) {
    return ch >= '0' && ch <= '9';
}

static boolean isLowerCase(char ch) {
    return ch >= 'a' && ch <= 'z';
}

static boolean isUpperCase(char ch) {
    return ch >= 'A' && ch <= 'Z';
}

let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)

I was able to fix the problem by changing the maximum-pool size value from one to two

spring.datasource.hikari.maximum-pool-size=2

First of all, you should be aware that UIButton already has a UILabel inside it. You can set it using –setTitle:forState:.

The problem with your example is that you need to set UILabel's numberOfLines property to something other than its default value of 1. You should also review the lineBreakMode property.

For this you can use text-overflow: ellipsis; property. Write like this

span {_x000D_
    display: inline-block;_x000D_
    width: 180px;_x000D_
    white-space: nowrap;_x000D_
    overflow: hidden !important;_x000D_
    text-overflow: ellipsis;_x000D_
}

<span>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book</span>

I too found Python lacking when it comes to reading and writing binary files, so I wrote a small module (for Python 3.6+).

With binaryfile you'd do something like this (I'm guessing, since I don't know Fortran):

import binaryfile

def particle_file(f):
    f.array('group_ids')  # Declare group_ids to be an array (so we can use it in a loop)
    f.skip(4)  # Bytes 1-4
    num_particles = f.count('num_particles', 'group_ids', 4)  # Bytes 5-8
    f.int('num_groups', 4)  # Bytes 9-12
    f.skip(8)  # Bytes 13-20
    for i in range(num_particles):
        f.struct('group_ids', '>f')  # 4 bytes x num_particles
    f.skip(4)

with open('myfile.bin', 'rb') as fh:
    result = binaryfile.read(fh, particle_file)
print(result)

Which produces an output like this:

{
    'group_ids': [(1.0,), (0.0,), (2.0,), (0.0,), (1.0,)],
    '__skipped': [b'\x00\x00\x00\x08', b'\x00\x00\x00\x08\x00\x00\x00\x14', b'\x00\x00\x00\x14'],
    'num_particles': 5,
    'num_groups': 3
}

I used skip() to skip the additional data Fortran adds, but you may want to add a utility to handle Fortran records properly instead. If you do, a pull request would be welcome.

Use mysql_num_rows(), to check if rows are available or not

$result = mysql_query("SELECT * FROM preditors_assigned WHERE lecture_name='$lectureName' LIMIT 1");
$num_rows = mysql_num_rows($result);

if ($num_rows > 0) {
  // do something
}
else {
  // do something else
}

In my case, I had to install the Microsoft.Owin.Host.SystemWeb package.

I was getting the same message as you did, but then noticed I couldn't even hit a breakpoint in Startup.cs which then let me to this SO thread.

Further to @cw24's answer  •  as of Laravel 5.4 you would instead have the following amendment in public/index.php

try {
    $response = $kernel->handle(
        $request = Illuminate\Http\Request::capture()
    );
} catch(\Exception $e) {
    echo "<pre>";
    echo $e;
    echo "</pre>";
}

And in my case, I had forgotten to fire up MySQL.
Which, by the way, is usually mysql.server start in Terminal

In C++0x you will be able to do it in the same way that you did with an array, but not in the current standard.

With only language support you can use:

int tmp[] = { 10, 20, 30 };
std::vector<int> v( tmp, tmp+3 ); // use some utility to avoid hardcoding the size here

If you can add other libraries you could try boost::assignment:

vector<int> v = list_of(10)(20)(30);

To avoid hardcoding the size of an array:

// option 1, typesafe, not a compile time constant
template <typename T, std::size_t N>
inline std::size_t size_of_array( T (&)[N] ) {
   return N;
}
// option 2, not typesafe, compile time constant
#define ARRAY_SIZE(x) (sizeof(x) / sizeof(x[0]))

// option 3, typesafe, compile time constant
template <typename T, std::size_t N>
char (&sizeof_array( T(&)[N] ))[N];    // declared, undefined
#define ARRAY_SIZE(x) sizeof(sizeof_array(x))

Real life example:

public class Control {
    public static final long EXPIRED_ON = 1386082988202l;
    public static final boolean isExpired() {
        return (System.currentTimeMillis() > EXPIRED_ON);
    }
}

Then in other classes, I can exit if the code has expired. If I reference the EXPIRED_ON variable from another class, the constant is inline to the byte code, making it very hard to track down all places in the code that checks the expiry date. However, if the other classes invoke the isExpired() method, the actual method is called, meaning a hacker could replace the isExpired method with another which always returns false.

I agree it would be very nice to force a compiler to inline the static final method to all classes which reference it. In that case, you need not even include the Control class, as it would not be needed at runtime.

From my research, this cannot be done. Perhaps some Obfuscator tools can do this, or, you could modify your build process to edit sources before compile.

As for proving if the method from the control class is placed inline to another class during compile, try running the other class without the Control class in the classpath.

SELECT UPPER(firstname) FROM Person

SELECT LOWER(firstname) FROM Person

I don't think Java 1.5 support concurrent TimeUnit. Otherwise, I would suggest for TimeUnit. Below is based on pure math approach.

stopWatch.stop();
long milliseconds = stopWatch.getTime();

int seconds = (int) ((milliseconds / 1000) % 60);
int minutes = (int) ((milliseconds / 1000) / 60);

Instead of using <div>, it would be better to use to provide the <tr> (which you want to hide) an id and then hiding it using javascript.

Why not a/b/(c|d|e)? I just tried with Saxon XML library (wrapped up nicely with some Clojure goodness), and it seems to work. abc.xml is the doc described by OP.

(require '[saxon :as xml])
(def abc-doc (xml/compile-xml (slurp "abc.xml")))
(xml/query "a/b/(c|d|e)" abc-doc)
=> (#<XdmNode <c>C1</c>>
    #<XdmNode <d>D1</d>>
    #<XdmNode <e>E1</e>>
    #<XdmNode <c>C2</c>>
    #<XdmNode <d>D2</d>>
    #<XdmNode <e>E1</e>>)

If you have Multiple radio buttons in single form then

var myRadio1 = $('input[name=radioButtonName1]');
var value1 = myRadio1.filter(':checked').val();

var myRadio2 = $('input[name=radioButtonName2]');
var value2 = myRadio2.filter(':checked').val();

This is working for me.

Instead of using ->bindParam() you can pass the data only at the time of ->execute():

$data = [   ':item_name' => $_POST['item_name'],   ':item_type' => $_POST['item_type'],   ':item_price' => $_POST['item_price'],   ':item_description' => $_POST['item_description'],   ':image_location' => 'images/'.$_FILES['file']['name'],   ':status' => 0,   ':id' => 0, ];  $stmt->execute($data); 

In this way you would know exactly what values are going to be sent.

Sometimes another software can be holding this door and it can be the cause of this conflict, try change the door on the server.xml.

If you simply need to excute your stored procedure proc_name 'paramValue1' , 'paramValue2'... at the same time you are executing more than one query like one select query and stored procedure you have to add select * from tableName EXEC proc_name paramValue1 , paramValue2...

modified $.each function

$.fn.eachReturn = function(arr, callback) {
   var result = null;
   $.each(arr, function(index, value){
       var test = callback(index, value);
       if (test) {
           result = test;
           return false;
       }
   });
   return result ;
}

it will break loop on non-false/non-empty result and return it back, so in your case it would be

return $.eachReturn(someArray, function(i){
    ...

Try this :

   for match in re.finditer(r"\[P[^\]]*\](.*?)\[/P\]", subject):
        # match start: match.start()
        # match end (exclusive): match.end()
        # matched text: match.group()

Simply use the base transpose function t, wrapped with as.data.frame:

final_df <- as.data.frame(t(starting_df))
final_df
     A    B    C    D
a    1    2    3    4
b 0.02 0.04 0.06 0.08
c Aaaa Bbbb Cccc Dddd

Above updated. As docendo discimus pointed out, t returns a matrix. As Mark suggested wrapping it with as.data.frame gets back a data frame instead of a matrix. Thanks!

To see a list of the Eclipse release name and it's corresponding version number go to this website. http://en.wikipedia.org/wiki/Eclipse_%28software%29#Release

• Release Date Platform version
• Juno ?? June 2012 4.2?
• Indigo 22 June 2011 3.7
• Helios 23 June 2010 3.6
• Galileo 24 June 2009 3.5
• Ganymede 25 June 2008 3.4
• Europa 29 June 2007 3.3
• Callisto 30 June 2006 3.2
• Eclipse 3.1 28 June 2005 3.1
• Eclipse 3.0 21 June 2004 3.0

I too dislike the way that the Eclipse foundation DOES NOT use the version number for their downloads or on the Help -> About Eclipse dialog. They do display the version on the download webpage, but the actual file name is something like:

• eclipse-java-indigo-SR1-linux-gtk.tar.gz
• eclipse-java-helios-linux-gtk.tar.gz

But over time, you forget what release name goes with what version number. I would much prefer a file naming convention like:

• eclipse-3.7.1-java-indigo-SR1-linux-gtk.tar.gz
• eclipse-3.6-java-helios-linux-gtk.tar.gz

This way you get BOTH from the file name and it is sortable in a directory listing. Fortunately, they mostly choose names are alphabetically after the previous one (except for 3.4-Ganymede vs the newer 3.5-Galileo).

Only a teacher would ask you to do something silly like this. You could provide an expected answer. Or a unique solution, while the rest of the class will be (yawn) the same...

from operator import lt, gt
def ultimate (l,op,c=1,u=0):
    try:
        if op(l[c],l[u]): 
            u = c
        c += 1
        return ultimate(l,op,c,u)
    except IndexError:
        return l[u]
def minimum (l):
    return ultimate(l,lt)
def maximum (l):
    return ultimate(l,gt)

The solution is simple. Use this to set yourself apart from obvious choices.

Interop with other languages founded on the DLR is #1 reason I can think of. You can't pass them a Dictionary<string, object> as it's not an IDynamicMetaObjectProvider. Another added benefit is that it implements INotifyPropertyChanged which means in the databinding world of WPF it also has added benefits beyond what Dictionary<K,V> can provide you.

You can use either resample or Grouper (which resamples under the hood).

First make sure that the datetime column is actually of datetimes (hit it with pd.to_datetime). It's easier if it's a DatetimeIndex:

In [11]: df1
Out[11]:
            abc  xyz
Date
2013-06-01  100  200
2013-06-03  -20   50
2013-08-15   40   -5
2014-01-20   25   15
2014-02-21   60   80

In [12]: g = df1.groupby(pd.Grouper(freq="M"))  # DataFrameGroupBy (grouped by Month)

In [13]: g.sum()
Out[13]:
            abc  xyz
Date
2013-06-30   80  250
2013-07-31  NaN  NaN
2013-08-31   40   -5
2013-09-30  NaN  NaN
2013-10-31  NaN  NaN
2013-11-30  NaN  NaN
2013-12-31  NaN  NaN
2014-01-31   25   15
2014-02-28   60   80

In [14]: df1.resample("M", how='sum')  # the same
Out[14]:
            abc  xyz
Date
2013-06-30   40  125
2013-07-31  NaN  NaN
2013-08-31   40   -5
2013-09-30  NaN  NaN
2013-10-31  NaN  NaN
2013-11-30  NaN  NaN
2013-12-31  NaN  NaN
2014-01-31   25   15
2014-02-28   60   80

Note: Previously pd.Grouper(freq="M") was written as pd.TimeGrouper("M"). The latter is now deprecated since 0.21.

I had thought the following would work, but it doesn't (due to as_index not being respected? I'm not sure.). I'm including this for interest's sake.

If it's a column (it has to be a datetime64 column! as I say, hit it with to_datetime), you can use the PeriodIndex:

In [21]: df
Out[21]:
        Date  abc  xyz
0 2013-06-01  100  200
1 2013-06-03  -20   50
2 2013-08-15   40   -5
3 2014-01-20   25   15
4 2014-02-21   60   80

In [22]: pd.DatetimeIndex(df.Date).to_period("M")  # old way
Out[22]:
<class 'pandas.tseries.period.PeriodIndex'>
[2013-06, ..., 2014-02]
Length: 5, Freq: M

In [23]: per = df.Date.dt.to_period("M")  # new way to get the same

In [24]: g = df.groupby(per)

In [25]: g.sum()  # dang not quite what we want (doesn't fill in the gaps)
Out[25]:
         abc  xyz
2013-06   80  250
2013-08   40   -5
2014-01   25   15
2014-02   60   80

To get the desired result we have to reindex...

I had this issue today and replace / trim did the trick..see below.

update table_foo 
set column_bar  = REPLACE(LTRIM(RTRIM(column_bar)), '  ', '')

before and after :

old-bad:  column_bar    |   New-fixed:   column_bar
       '  xyz  '        |                'xyz'   
       '  xyz  '        |                'xyz' 
       '  xyz  '        |                'xyz' 
       '  xyz  '        |                'xyz' 
       '  xyz  '        |                'xyz' 
       '  xyz  '        |                'xyz' 

To get exactly the same thing as base_url of codeigniter, you can do:

var base_url = window.location.origin + '/' + window.location.pathname.split ('/') [1] + '/';

this will be more useful if you work on pure Javascript file.

If any of the code in the try block can throw a checked exception, it has to appear in the throws clause of the method signature. If an unchecked exception is thrown, it's bubbled out of the method.

The finally block is always executed, whether an exception is thrown or not.

@Controller
public class HomeController {

    @RequestMapping(method = RequestMethod.GET, value = "/")
    public ModelAndView welcome() {
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("login.html");
        return modelAndView;
    }
}

This will return the Login.html File. The Login.html should be inside the static Folder.

Note: thymeleaf dependency is not added

@RestController
public class HomeController {

    @RequestMapping(method = RequestMethod.GET, value = "/")
    public String welcome() {
        return "login";
    }
}

This will return the String login

Minor variation to user1850980's answer (for the question "How to initialize a list of empty dictionaries") using list constructor:

dictlistGOOD = list( {} for i in xrange(listsize) )

I found out to my chagrin, this does NOT work:

dictlistFAIL = [{}] * listsize  # FAIL!

as it creates a list of references to the same empty dictionary, so that if you update one dictionary in the list, all the other references get updated too.

Try these updates to see the difference:

dictlistGOOD[0]["key"] = "value"
dictlistFAIL[0]["key"] = "value"

(I was actually looking for user1850980's answer to the question asked, so his/her answer was helpful.)

I have tried to invoke

String oldDir = System.setProperty("user.dir", currdir.getAbsolutePath());

It seems to work. But

File myFile = new File("localpath.ext"); InputStream openit = new FileInputStream(myFile);

throws a FileNotFoundException though

myFile.getAbsolutePath()

shows the correct path. I have read this. I think the problem is:

• Java knows the current directory with the new setting.
• But the file handling is done by the operation system. It does not know the new set current directory, unfortunately.

The solution may be:

File myFile = new File(System.getPropety("user.dir"), "localpath.ext");

It creates a file Object as absolute one with the current directory which is known by the JVM. But that code should be existing in a used class, it needs changing of reused codes.

You had it nearly right in the last line. You want

str(bytes_string, 'utf-8')

because the type of bytes_string is bytes, the same as the type of b'abc'.

Then you'd want to do this instead:

print str(int(1.0/3.0*100))+'%'

The .0 denotes them as floats and int() rounds them to integers afterwards again.

You are simply sending signals to the processes. kill is a command to send those signals.

The keyboard command Ctrl+C sends a SIGINT, kill -9 sends a SIGKILL, and kill -15 sends a SIGTERM.

What signal do you want to send to your server to end it?

Yes it is, there have to be boolean expresion after IF. Here you have a direct link. I hope it helps. GL!

Sample DF:

In [79]: df = pd.DataFrame(np.random.randint(5, 15, (10, 3)), columns=list('abc'))

In [80]: df
Out[80]:
    a   b   c
0   6  11  11
1  14   7   8
2  13   5  11
3  13   7  11
4  13   5   9
5   5  11   9
6   9   8   6
7   5  11  10
8   8  10  14
9   7  14  13

present only those rows where b > 10

In [81]: df[df.b > 10]
Out[81]:
   a   b   c
0  6  11  11
5  5  11   9
7  5  11  10
9  7  14  13

Minimums (for all columns) for the rows satisfying b > 10 condition

In [82]: df[df.b > 10].min()
Out[82]:
a     5
b    11
c     9
dtype: int32

Minimum (for the b column) for the rows satisfying b > 10 condition

In [84]: df.loc[df.b > 10, 'b'].min()
Out[84]: 11

UPDATE: starting from Pandas 0.20.1 the .ix indexer is deprecated, in favor of the more strict .iloc and .loc indexers.

Save this class in the file StaticDemo.java. Also you cant have more than one public classes in one file.

Let's change tütü's code

private void disableEnableControls(boolean enable, ViewGroup vg){
for (int i = 0; i < vg.getChildCount(); i++){
   View child = vg.getChildAt(i);
   if (child instanceof ViewGroup){ 
      disableEnableControls(enable, (ViewGroup)child);
   } else {
     child.setEnabled(enable);
   }
 }
}

I think, there is no point in just making viewgroup disable. If you want to do it, there is another way I have used for exactly the same purpose. Create view as a sibling of your groupview :

<View
    android:visibility="gone"
    android:id="@+id/reservation_second_screen"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="bottom"
    android:background="#66ffffff"
    android:clickable="false" />

and at run-time, make it visible. Note: your groupview's parent layout should be either relative or frame layout. Hope this will help.

You can use a deep watcher for that:

watch: {
  item: {
     handler(val){
       // do stuff
     },
     deep: true
  }
}

This will now detect any changes to the objects in the item array and additions to the array itself (when used with Vue.set). Here's a JSFiddle: http://jsfiddle.net/je2rw3rs/

EDIT

If you don't want to watch for every change on the top level object, and just want a less awkward syntax for watching nested objects directly, you can simply watch a computed instead:

var vm = new Vue({
  el: '#app',
  computed: {
    foo() {
      return this.item.foo;
    }
  },
  watch: {
    foo() {
      console.log('Foo Changed!');
    }
  },
  data: {
    item: {
      foo: 'foo'
    }
  }
})

Here's the JSFiddle: http://jsfiddle.net/oa07r5fw/

I tested this code and it works great:

class MyClass: UIView {        
    class func instanceFromNib() -> UIView {
        return UINib(nibName: "nib file name", bundle: nil).instantiateWithOwner(nil, options: nil)[0] as UIView
    }    
}

Initialise the view and use it like below:

var view = MyClass.instanceFromNib()
self.view.addSubview(view)

OR

var view = MyClass.instanceFromNib
self.view.addSubview(view())

UPDATE Swift >=3.x & Swift >=4.x

class func instanceFromNib() -> UIView {
    return UINib(nibName: "nib file name", bundle: nil).instantiate(withOwner: nil, options: nil)[0] as! UIView
}

With lodash:

_.each([1, 2, 3], (item) => {
   doSomeThing(item);
});

//Or:
_.each([1, 2, 3], doSomeThing);

Or if you want to do something N times:

const N = 10;
_.times(N, () => {
   doSomeThing();
});

//Or shorter:
_.times(N, doSomeThing);

Refer to this link for lodash installation

It's better to use something like this:

s.split("[\\s\\-\\.\\'\\?\\,\\_\\@]+");

Have added a few other characters as sample. This is the safest way to use, because the way . and ' is treated.

One set of familiar operations that you can do in MapReduce is the set of normal SQL operations: SELECT, SELECT WHERE, GROUP BY, ect.

Another good example is matrix multiply, where you pass one row of M and the entire vector x and compute one element of M * x.

However, the previous answer could still be confusing for some programmers. Most especially beginners who are most probably using an older book or tutorial. Or perhaps you still feel the facade is needed. Sure you can use it. Me for one I still love to use the facade, this is because some times while building my api I forget to use the '\' before the Response.

if you are like me, simply add

   "use Response;"

above your class ...extends contoller. this should do.

with this you can now use:

$response = Response::json($posts, 200);

instead of:

$response = \Response::json($posts, 200);

Calling async code from synchronous code can be quite tricky.

I explain the full reasons for this deadlock on my blog. In short, there's a "context" that is saved by default at the beginning of each await and used to resume the method.

So if this is called in an UI context, when the await completes, the async method tries to re-enter that context to continue executing. Unfortunately, code using Wait (or Result) will block a thread in that context, so the async method cannot complete.

The guidelines to avoid this are:

1. Use ConfigureAwait(continueOnCapturedContext: false) as much as possible. This enables your async methods to continue executing without having to re-enter the context.
2. Use async all the way. Use await instead of Result or Wait.

If your method is naturally asynchronous, then you (probably) shouldn't expose a synchronous wrapper.

So far all proposed solutions work with separate char items, not code points. I'd like to propose two solutions to properly handle surrogate pairs as well (those are characters from U+10000 to U+10FFFF, composed of two char items).

1) One-line O(n logn) solution which utilizes Java 8 CharSequence.codePoints() stream:

static boolean areAnagrams(CharSequence a, CharSequence b) {
    return Arrays.equals(a.codePoints().sorted().toArray(),
                         b.codePoints().sorted().toArray());
}

2) Less elegant O(n) solution (in fact, it will be faster only for long strings with low chances to be anagrams):

static boolean areAnagrams(CharSequence a, CharSequence b) {
    int len = a.length();
    if (len != b.length())
        return false;

    // collect codepoint occurrences in "a"
    Map<Integer, Integer> ocr = new HashMap<>(64);
    a.codePoints().forEach(c -> ocr.merge(c, 1, Integer::sum));

    // for each codepoint in "b", look for matching occurrence
    for (int i = 0, c = 0; i < len; i += Character.charCount(c)) {
        int cc = ocr.getOrDefault((c = Character.codePointAt(b, i)), 0);
        if (cc == 0)                        
            return false;            
        ocr.put(c, cc - 1);
    }
    return true;
}

ECMAScript 6 version:

const toTitleCase = (phrase) => {
  return phrase
    .toLowerCase()
    .split(' ')
    .map(word => word.charAt(0).toUpperCase() + word.slice(1))
    .join(' ');
};

let result = toTitleCase('maRy hAd a lIttLe LaMb');
console.log(result);

strings = ("string1", "string2", "string3")
for line in file:
    if any(s in line for s in strings):
        print "yay!"

I would recommend using Glazed Lists for this. It makes it very easy to map a data structure to a table model.

To react to the mouseclick on the JTable, use an ActionListener: ActionListener on JLabel or JTable cell

Imho one of the simplest Solutions is: -

//MIN NUMBER
Collections.sort(listOfNumbers);
listOfNumbers.get(0);

//MAX NUMBER
Collections.sort(listOfNumbers);
Collections.reverse(listOfNumbers);
listOfNumbers.get(0);

You only need to include a throws clause on a method if the method throws a checked exception. If the method throws a runtime exception then there is no need to do so.

See here for some background on checked vs unchecked exceptions: http://download.oracle.com/javase/tutorial/essential/exceptions/runtime.html

If the method catches the exception and deals with it internally (as in your second example) then there is no need to include a throws clause.

My private key was set to permission 400 and was resulting in Permission denied setting it to '644' helped me .

key_load_private_type: Permission denied is the specific error I was getting

Solution: Sudo chmod 644 <key.pem>

Note: set to 644 is must, it was not working with 400

>>> u"\u00b0"
u'\xb0'
>>> print _

BTW, all I did was search "unicode degree" on Google. This brings up two results: "Degree sign U+00B0" and "Degree Celsius U+2103", which are actually different:

>>> u"\u2103"
u'\u2103'
>>> print _

Not sure why the code above did not work for the library rgl, but the following link has a great example with the same library. Run the code in R and you will obtain a beautiful 3d plot that you can turn around in all angles.

This is the official example, may be better for some. It is under their Experiments examples section, but since it is official, it should be kept up to date with the current bootstrap release.

Looks like they have added an off canvas css file used in their example:

http://getbootstrap.com/examples/offcanvas/offcanvas.css

And some JS code:

$(document).ready(function () {
  $('[data-toggle="offcanvas"]').click(function () {
    $('.row-offcanvas').toggleClass('active')
  });
});

If you just need the indexed columns EXEC sp_helpindex 'TABLE_NAME'

use the scan method e.g.

 curl -XGET 'localhost:9200/_search?search_type=scan&scroll=10m&size=50' -d '
 {
    "query" : {
       "match_all" : {}

I have had to use code like this to provide functions to allocate memory to a pointer passed in and return its size because my company "object" to me using the STL

 int iSizeOfArray(int* &piArray) {
    piArray = new int[iNumberOfElements];
    ...
    return iNumberOfElements;
 }

It is not nice, but the pointer must be passed by reference (or use double pointer). If not, memory is allocated to a local copy of the pointer if it is passed by value which results in a memory leak.

You can use the formula INDIRECT().

This basically takes a string and treats it as a reference. In your case, you would use:

=INDIRECT("'"&A5&"'!G7")

The double quotes are to show that what's inside are strings, and only A5 here is a reference.

You can extract that part of the URL using a simple regular expression:

var url = location.href;
var className = url.match(/\w+\/(\w+)_/)[1];
$('body').addClass(className);

@Jason is correct in a way but not entirely.

update

Update the registered submodules, i.e. clone missing submodules and checkout the commit specified in the index of the containing repository. This will make the submodules HEAD be detached unless --rebase or --merge is specified or the key submodule.$name.update is set to rebase or merge.

So, git submodule update does checkout, but it is to the commit in the index of the containing repository. It does not yet know of the new commit upstream at all. So go to your submodule, get the commit you want and commit the updated submodule state in the main repository and then do the git submodule update.

box-shadow: -15px 0px 17px -7px rgba(0,0,0,0.75);

The first px value is the "Horizontal Length" set to -15px to position the shadow towards the left, the next px value is set to 0 so the shadow top and bottom is centred to minimise the top and bottom shadow.

The third value(17px) is known as the blur radius. The higher the number, the more blurred the shadow will be. And then last px value -7px is The spread radius, a positive value increases the size of the shadow, a negative value decreases the size of the shadow, at -7px it keeps the shadow from appearing above and below the item.

There are declared arrays and arrays that are not declared, but otherwise created, particularly using new:

int *p = new int[3];

That array with 3 elements is created dynamically (and that 3 could have been calculated at runtime, too), and a pointer to it which has the size erased from its type is assigned to p. You cannot get the size anymore to print that array. A function that only receives the pointer to it can thus not print that array.

Printing declared arrays is easy. You can use sizeof to get their size and pass that size along to the function including a pointer to that array's elements. But you can also create a template that accepts the array, and deduces its size from its declared type:

template<typename Type, int Size>
void print(Type const(& array)[Size]) {
  for(int i=0; i<Size; i++)
    std::cout << array[i] << std::endl;
}

The problem with this is that it won't accept pointers (obviously). The easiest solution, I think, is to use std::vector. It is a dynamic, resizable "array" (with the semantics you would expect from a real one), which has a size member function:

void print(std::vector<int> const &v) {
  std::vector<int>::size_type i;
  for(i = 0; i<v.size(); i++)
    std::cout << v[i] << std::endl;
}

You can, of course, also make this a template to accept vectors of other types.

import re

url = '<p>Hello World</p><a href="http://example.com">More Examples</a><a href="http://example2.com">Even More Examples</a>'

urls = re.findall('https?://(?:[-\w.]|(?:%[\da-fA-F]{2}))+', url)

>>> print urls
['http://example.com', 'http://example2.com']

you can turn the ":" to space, and do the split.eg

>>> f=open("/proc/net/dev")
>>> for line in f:
...     line=line.replace(":"," ").split()
...     print len(line)

no regex needed (for this case)

Currently some people are facing the same issue because of using 12.0.0 version of AdMob lib.

Update it to 12.0.1. This should fix it. You can read more here

You can also use ctypes to tap into the Windows API and avoid the massive pywin32 package. This is what I use (excuse the poor style, but the idea is there):

import ctypes

# Get required functions, strcpy..
strcpy = ctypes.cdll.msvcrt.strcpy
ocb = ctypes.windll.user32.OpenClipboard    # Basic clipboard functions
ecb = ctypes.windll.user32.EmptyClipboard
gcd = ctypes.windll.user32.GetClipboardData
scd = ctypes.windll.user32.SetClipboardData
ccb = ctypes.windll.user32.CloseClipboard
ga = ctypes.windll.kernel32.GlobalAlloc    # Global memory allocation
gl = ctypes.windll.kernel32.GlobalLock     # Global memory Locking
gul = ctypes.windll.kernel32.GlobalUnlock
GMEM_DDESHARE = 0x2000

def Get():
  ocb(None) # Open Clip, Default task

  pcontents = gcd(1) # 1 means CF_TEXT.. too lazy to get the token thingy...

  data = ctypes.c_char_p(pcontents).value

  #gul(pcontents) ?
  ccb()

  return data

def Paste(data):
  ocb(None) # Open Clip, Default task

  ecb()

  hCd = ga(GMEM_DDESHARE, len(bytes(data,"ascii")) + 1)

  pchData = gl(hCd)

  strcpy(ctypes.c_char_p(pchData), bytes(data, "ascii"))

  gul(hCd)

  scd(1, hCd)

  ccb()

One problem with option 1 in answer from Victor Zamanian is that if the type isn't exported then users of your package can't declare it as the type for function parameters etc. One way around this would be to export an interface instead of the struct e.g.

package candidate
// Exporting interface instead of struct
type Candidate interface {}
// Struct is not exported
type candidate struct {
    Name string
    Votes uint32 // Defaults to 0
}
// We are forced to call the constructor to get an instance of candidate
func New(name string) Candidate {
    return candidate{name, 0}  // enforce the default value here
}

Which lets us declare function parameter types using the exported Candidate interface. The only disadvantage I can see from this solution is that all our methods need to be declared in the interface definition, but you could argue that that is good practice anyway.

The simplest way imo:

(It can also be used with emails for example)

public static matchValues(
    matchTo: string // name of the control to match to
  ): (AbstractControl) => ValidationErrors | null {
    return (control: AbstractControl): ValidationErrors | null => {
      return !!control.parent &&
        !!control.parent.value &&
        control.value === control.parent.controls[matchTo].value
        ? null
        : { isMatching: false };
    };
}

In your Component:

this.SignUpForm = this.formBuilder.group({

password: [undefined, [Validators.required]],
passwordConfirm: [undefined, 
        [
          Validators.required,
          matchValues('password'),
        ],
      ],
});

Follow up:

As others pointed out in the comments, if you fix the error by fixing the password field the error won't go away, Because the validation triggers on passwordConfirm input. This can be fixed by a number of ways. I think the best is:

this.SignUpForm .controls.password.valueChanges.subscribe(() => {
  this.SignUpForm .controls.confirmPassword.updateValueAndValidity();
});

On password change, revliadte confirmPassword.

Use:

//REVENUE_YEAR[starts-with(.,'2552')]/../REGION/text() 

This will give you DD MM YYYY YY HH Min Sec variables and works on any Windows machine from XP Pro and later.

set "YY=%dt:~2,2%" & set "YYYY=%dt:~0,4%" & set "MM=%dt:~4,2%" & set "DD=%dt:~6,2%"
set "HH=%dt:~8,2%" & set "Min=%dt:~10,2%" & set "Sec=%dt:~12,2%"

set "datestamp=%YYYY%%MM%%DD%" & set "timestamp=%HH%%Min%%Sec%"
set "fullstamp=%YYYY%-%MM%-%DD%_%HH%-%Min%-%Sec%"
echo datestamp: "%datestamp%"

sys.executable is not reliable if working in an embedded python environment. My suggestions is to deduce it from

import os
os.__file__

Copy a file from one location to another location means,need to copy the whole content to another location.Files.copy(Path source, Path target, CopyOption... options) throws IOException this method expects source location which is original file location and target location which is a new folder location with destination same type file(as original). Either Target location needs to exist in our system otherwise we need to create a folder location and then in that folder location we need to create a file with the same name as original filename.Then using copy function we can easily copy a file from one location to other.

 public static void main(String[] args) throws IOException {
                String destFolderPath = "D:/TestFile/abc";
                String fileName = "pqr.xlsx";
                String sourceFilePath= "D:/TestFile/xyz.xlsx";
                File f = new File(destFolderPath);
                if(f.mkdir()){
                    System.out.println("Directory created!!!!");
                }
                else {
                    System.out.println("Directory Exists!!!!");
                }
                f= new File(destFolderPath,fileName);
                if(f.createNewFile())   {

                    System.out.println("File Created!!!!");
                }   else {
                    System.out.println("File exists!!!!");
                }

                Files.copy(Paths.get(sourceFilePath), Paths.get(destFolderPath, fileName),REPLACE_EXISTING);
                System.out.println("Copy done!!!!!!!!!!!!!!");


            }

Another option would be file_get_contents():

// $xml_str = your xml
// $url = target url

$post_data = array('xml' => $xml_str);
$stream_options = array(
    'http' => array(
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded' . "\r\n",
        'content' =>  http_build_query($post_data)));

$context  = stream_context_create($stream_options);
$response = file_get_contents($url, null, $context);

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

This script is a improvement of the script from Vector. I have made a little change to it. So this script works for every link with the class page-scroll in it.

At first without easing:

$("a.page-scroll").click(function() {
    var targetDiv = $(this).attr('href');
    $('html, body').animate({
        scrollTop: $(targetDiv).offset().top
    }, 1000);
});

For easing you will need Jquery UI:

<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js"></script>

Add this to the script:

'easeOutExpo'

Final

$("a.page-scroll").click(function() {
    var targetDiv = $(this).attr('href');
    $('html, body').animate({
        scrollTop: $(targetDiv).offset().top
    }, 1000, 'easeOutExpo');
});

All the easings you can find here: Cheat Sheet.

git mv oldname newname

is just shorthand for:

mv oldname newname
git add newname
git rm oldname

i.e. it updates the index for both old and new paths automatically.

If you want to count the number of records in your table, simply run:

    SELECT COUNT(*) FROM your_table;

You could use SqlMethods.Like(matchExpression,pattern)

var results = from c in db.costumers
              where SqlMethods.Like(c.FullName, "%"+FirstName+"%,"+LastName)
              select c;

The use of this method outside of LINQ to SQL will always throw a NotSupportedException exception.

GVIM runs on Windows, and there is VIM for cmd.

Check http://www.vim.org/download.php

Also, a quick look through the docs or google, or some vimmy friends can help you to use VIM's quick search and replace to fix the problem you are having I believe.

window.location is just what you need. Other thing you can do is to create anchor element and simulate click on it

$("<a href='your url'></a>").click(); 

No requires converting the Task to int. Simply Use The Task Result.

int taskResult = AccessTheWebAndDouble().Result;

public async Task<int> AccessTheWebAndDouble()
{
    int task = AccessTheWeb();
    return task;
}

It will return the value if available otherwise it return 0.

I solved this problem by first verifying the that remote did not have anything checked out (it really was not supposed to), and then made it bare with:

$ git config --bool core.bare true

After that git push worked fine.

It's called a Favicon, have a read.

<link rel="shortcut icon" href="http://www.example.com/myicon.ico"/>

You can use this neat tool to generate cross-browser compatible Favicons.

There is a Linux command for that: base64

base64 DSC_0251.JPG >DSC_0251.b64

To assign result to variable use

test=`base64 DSC_0251.JPG`

SELECT DATE(ColumnName) FROM tablename;

More on MySQL DATE() function.

This is called a correlated update

UPDATE table1 t1
   SET (name, desc) = (SELECT t2.name, t2.desc
                         FROM table2 t2
                        WHERE t1.id = t2.id)
 WHERE EXISTS (
    SELECT 1
      FROM table2 t2
     WHERE t1.id = t2.id )

Assuming the join results in a key-preserved view, you could also

UPDATE (SELECT t1.id, 
               t1.name name1,
               t1.desc desc1,
               t2.name name2,
               t2.desc desc2
          FROM table1 t1,
               table2 t2
         WHERE t1.id = t2.id)
   SET name1 = name2,
       desc1 = desc2

Try this

'''
This is a multiline
comment. I can type here whatever I want.
'''

Python does have a multiline string/comment syntax in the sense that unless used as docstrings, multiline strings generate no bytecode -- just like #-prepended comments. In effect, it acts exactly like a comment.

On the other hand, if you say this behavior must be documented in the official docs to be a true comment syntax, then yes, you would be right to say it is not guaranteed as part of the language specification.

In any case your editor should also be able to easily comment-out a selected region (by placing a # in front of each line individually). If not, switch to an editor that does.

Programming in Python without certain text editing features can be a painful experience. Finding the right editor (and knowing how to use it) can make a big difference in how the Python programming experience is perceived.

Not only should the editor be able to comment-out selected regions, it should also be able to shift blocks of code to the left and right easily, and should automatically place the cursor at the current indentation level when you press Enter. Code folding can also be useful.

I have tried everything - but nothing helped. After searching for several hours I found this information:

Apache 2.4.18 for some reason does not load php 7.2 curl. I updated my Apache to 2.4.29 and curl loaded instantly

http://forum.wampserver.com/read.php?2,149346,149348

What should I say: I updated Apache and curl was running like charm

1. Copy your source folder to somedir:

   cp -r srcdir somedir

2. Remove all unneeded files:

   find somedir -name '.svn' -exec rm -rf {} \+

3. launch scp from somedir

 by_type_year_tag_filtered <- by_type_year_tag %>%
      dplyr:: filter(tag_name %in% c("dplyr", "ggplot2"))

I assume you use Graphics.CopyFromScreen to get the screenshot.

You can use P/Invoke to GetForegroundWindow (and then get its position and size) to determine which region you need to copy from.

The answer given by Nico O is correct. However this doesn't get the desired result on Internet Explorer 10 to 11 and Firefox.

For IE, I found that changing

.flex > div
{
   flex: 1 0 50%;
}

to

.flex > div
{
   flex: 1 0 45%;
}

seems to do the trick. Don't ask me why, I haven't gone any further into this but it might have something to do with how IE renders the border-box or something.

In the case of Firefox I solved it by adding

display: inline-block;

to the items.

Change multiple files by extension to UTF-8 without BOM:

$Utf8NoBomEncoding = New-Object System.Text.UTF8Encoding($False)
foreach($i in ls -recurse -filter "*.java") {
    $MyFile = Get-Content $i.fullname 
    [System.IO.File]::WriteAllLines($i.fullname, $MyFile, $Utf8NoBomEncoding)
}

for i in ('apple', 'banana', 'carrot'):
    fruitdict[i] = locals()[i]

Use Entry.insert. For example:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
e = Entry(root)
e.insert(END, 'default text')
e.pack()
root.mainloop()

Or use textvariable option:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
v = StringVar(root, value='default text')
e = Entry(root, textvariable=v)
e.pack()
root.mainloop()

I can't comment because my reputation is not high enough. @Franklin Rivero if you are using Laravel 5.2 you can set the bindings on the main query instead of the join using the setBindings method.

So the main query in @ph4r05's answer would look something like this:

$q = DnsResult::query()
    ->from($dnsTable . ' AS s')
    ->join(
        DB::raw('(' . $qqSql. ') AS ss'),
        function(JoinClause $join) {
            $join->on('s.watch_id', '=', 'ss.watch_id')
                 ->on('s.last_scan_at', '=', 'ss.last_scan');
        })
    ->setBindings($subq->getBindings());

Let's assume that your branch is called master both locally and remotely, and that your remote is called origin you could do:

git reflog to get all the commit history, your commit hash has format like this: e34e1ff

git reset --hard <commit-hash>

git push -f origin master

If you are trying to load a file which is not in the same directory as your Java class, you've got to use the runtime directory structure rather than the one which appears at design time.

To find out what the runtime directory structure is, check your {root project dir}/target/classes directory. This directory is accessible via the "." URL.

Based on user4284592's answer, the following worked for me:

ClassLoader cl = getClass().getClassLoader();
File file = new File(cl.getResource("./docs/doc.pdf").getFile());

with the following directory structure:

{root dir}/target/classes/docs/doc.pdf

Here's an explanation, so you don't just blindly copy and paste my code:

• java.lang.ClassLoader is an object that is responsible for loading classes. Every Class object contains a reference to the ClassLoader that defined it and can fetch it with getClassLoader() method.
• ClassLoader's getResource method finds the resource with the given name. A resource is some data that can be accessed by class code in a way that is independent of the location of the code.

If you're looking for the RPM.

rpm -qa | grep MySQL

Most of it's data is stored in /var/lib/mysql so that's another good place to look.

If it is installed

which mysql

will give you the location of the binary.

You could also do an

updatedb

and a

locate mysql

to find any mysql files.

You refer to 'x' from window object

var x = 0;

function a(key, ref) {
    ref = ref || window;  // object reference - default window
    ref[key]++;
}

a('x');                   // string
alert(x);

add dependency for retrofit2

compile 'com.google.code.gson:gson:2.6.2'
compile 'com.squareup.retrofit2:retrofit:2.0.2'
compile 'com.squareup.retrofit2:converter-gson:2.0.2'

create class for base url

public class ApiClient     
{
public static final String BASE_URL = "base_url";

private static Retrofit retrofit = null;

public static Retrofit getClient() {
    if (retrofit==null) {
        retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .build();
    }
    return retrofit;
}

}

after that create class model to get value

public class ApprovalModel {

@SerializedName("key_parameter")
private String approvalName;
public String getApprovalName() {
    return approvalName;
}
}

create interface class

public interface ApiInterface { 
@GET("append_url")
Call<CompanyDetailsResponse> getCompanyDetails();
}

after that in main class

 if(Connectivity.isConnected(mContext)){
            final ProgressDialog mProgressDialog = new ProgressDialog(mContext);
            mProgressDialog.setIndeterminate(true);
            mProgressDialog.setMessage("Loading...");
            mProgressDialog.show();

            ApiInterface apiService =
                    ApiClient.getClient().create(ApiInterface.class);

            Call<CompanyDetailsResponse> call = apiService.getCompanyDetails();
            call.enqueue(new Callback<CompanyDetailsResponse>() {
                @Override
                public void onResponse(Call<CompanyDetailsResponse>call, Response<CompanyDetailsResponse> response) {
                    mProgressDialog.dismiss();
                    if(response!=null && response.isSuccessful()) {
                        List<CompanyDetails> companyList = response.body().getCompanyDetailsList();

                        if (companyList != null&&companyList.size()>0) {
                            for (int i = 0; i < companyList.size(); i++) {
                                Log.d(TAG, "" + companyList.get(i));
                            }
                         //get values
                        }else{
                            //show alert not get value
                        }
                    }else{
                        //show error message

                    }
                }

                @Override
                public void onFailure(Call<CompanyDetailsResponse>call, Throwable t) {
                    // Log error here since request failed
                    Log.e(TAG, t.toString());
                    mProgressDialog.dismiss();
                }
            });
        }else{
            //network error alert box

        }

I have combined all the answers in one and come up with the following code:

jQuery('#input_id', function(e){
    // Allow: backspace, delete, tab, escape, enter
    if (jQuery.inArray(e.keyCode, [46, 8, 9, 27, 13, 110]) !== -1 ||
        // Allow: Ctrl+A
        (e.keyCode === 65 && e.ctrlKey === true) ||
        // Allow: Ctrl+C
        (e.keyCode === 67 && e.ctrlKey === true) ||
        // Allow: Ctrl+X
        (e.keyCode === 88 && e.ctrlKey === true) ||
        // Disallow several dots (allow 190 only if no dots found)
        (e.keyCode === 190 && jQuery(this).val().indexOf('.') == -1) ||
        // Bug in some Android devices where it is always 229
        (e.keyCode === 229) ||
        // Allow: home, end, left, right
        (e.keyCode >= 35 && e.keyCode <= 40)) {
        // let it happen, don't do anything
        return;
    }
    // Ensure that it is a number and stop the keypress
    if ((e.shiftKey || (e.keyCode < 48 || e.keyCode > 57)) && (e.keyCode < 96 || e.keyCode > 105)) {
        e.preventDefault();
    }
});

In addition the form should have autocomplete="off". Without this option you might have issues with auto-complete algorithms on mobile devices.

Instead of calling the function, bind the value to the function:

this.props.removeTaskFunction.bind(this, todo)

MDN ref: https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_objects/Function/bind

I don't know if this is still actual for you, but I still leave my comment so maybe it will help somebody else. I had same issue, and the solution proposed by @dighan on bountysource.com/issues/ solved it for me.

So here is the code that solved my problem:

var media = document.getElementById("YourVideo");
const playPromise = media.play();
if (playPromise !== null){
    playPromise.catch(() => { media.play(); })
}

It still throws an error into console, but at least the video is playing :)

Table Creating

create table emp(eno int identity(100001,1),ename varchar(50))

Values inserting

insert into emp(ename)values('narendra'),('ajay'),('anil'),('raju')

Select Table

select * from emp

Output

eno     ename
100001  narendra
100002  rama
100003  ajay
100004  anil
100005  raju
