Programs & Examples On #Constant expression

Check the variables before building the query, if they are empty, change them to the string NULL

don't try to do this

$ make action value1 value2

instead create script:

#! /bin/sh
# rebuild if necessary
make
# do action with arguments
action "$@"

and do this:

$ ./buildthenaction.sh value1 value2

for more explanation why do this and caveats of makefile hackery read my answer to another very similar but seemingly not duplicate question: Passing arguments to "make run"

Let's assume you have install target, which is a very common in makefiles. If you do not use .PHONY, and a file named install exists in the same directory as the Makefile, then make install will do nothing. This is because Make interprets the rule to mean "execute such-and-such recipe to create the file named install". Since the file is already there, and its dependencies didn't change, nothing will be done.

However if you make the install target PHONY, it will tell the make tool that the target is fictional, and that make should not expect it to create the actual file. Hence it will not check whether the install file exists, meaning: a) its behavior will not be altered if the file does exist and b) extra stat() will not be called.

Generally all targets in your Makefile which do not produce an output file with the same name as the target name should be PHONY. This typically includes all, install, clean, distclean, and so on.

Simple way? Use strip_tags():

$str = strip_tags($input);

You can also use filter_var() for that:

$str = filter_var($input, FILTER_SANITIZE_STRING);

The advantage of filter_var() is that you can control the behaviour by, for example, stripping or encoding low and high characters.

Here is a list of sanitizing filters.

Why not create an extension method? That's more readable.

public static IEnumerable<FileInfo> GetFilesByExtensions(this DirectoryInfo dir, params string[] extensions)
{
    if (extensions == null) 
         throw new ArgumentNullException("extensions");
    IEnumerable<FileInfo> files = Enumerable.Empty<FileInfo>();
    foreach(string ext in extensions)
    {
       files = files.Concat(dir.GetFiles(ext));
    }
    return files;
}

EDIT: a more efficient version:

public static IEnumerable<FileInfo> GetFilesByExtensions(this DirectoryInfo dir, params string[] extensions)
{
    if (extensions == null) 
         throw new ArgumentNullException("extensions");
    IEnumerable<FileInfo> files = dir.EnumerateFiles();
    return files.Where(f => extensions.Contains(f.Extension));
}

Usage:

DirectoryInfo dInfo = new DirectoryInfo(@"c:\MyDir");
dInfo.GetFilesByExtensions(".jpg",".exe",".gif");

Tips from 2020:

From Flask 1.0, it defaults to enable multiple threads (source), you don't need to do anything, just upgrade it with:

$ pip install -U flask

If you are using flask run instead of app.run() with older versions, you can control the threaded behavior with a command option (--with-threads/--without-threads):

$ flask run --with-threads

It's same as app.run(threaded=True)

My suggestion:

using System.Linq;

string myStringOutput = String.Join(",", myArray.Select(p => p.ToString()).ToArray());

reference: https://coderwall.com/p/oea7uq/convert-simple-int-array-to-string-c

The answers are commonly found in Java books.

1. cloning: If you don't override clone method, the default behavior is shallow copy. If your objects have only primitive member variables, it's totally ok. But in a typeless language with another object as member variables, it's a headache.

2. serialization/deserialization

$new_object = unserialize(serialize($your_object))

This achieves deep copy with a heavy cost depending on the complexity of the object.

For completeness, we should mention PEP3119 where ABC was introduced and compared with interfaces, and original Talin's comment.

The abstract class is not perfect interface:

• belongs to the inheritance hierarchy
• is mutable

But if you consider writing it your own way:

def some_function(self):
     raise NotImplementedError()

interface = type(
    'your_interface', (object,),
    {'extra_func': some_function,
     '__slots__': ['extra_func', ...]
     ...
     '__instancecheck__': your_instance_checker,
     '__subclasscheck__': your_subclass_checker
     ...
    }
)

ok, rather as a class
or as a metaclass
and fighting with python to achieve the immutable object
and doing refactoring
...

you'll quite fast realize that you're inventing the wheel to eventually achieve abc.ABCMeta

abc.ABCMeta was proposed as a useful addition of the missing interface functionality, and that's fair enough in a language like python.

Certainly, it was able to be enhanced better whilst writing version 3, and adding new syntax and immutable interface concept ...

Conclusion:

The abc.ABCMeta IS "pythonic" interface in python

With Swift 5 and iOS 12, according to your needs, you may use one of the two following ways to find the difference between two dates in days.

#1. Using Calendar's dateComponents(_:from:to:) method

import Foundation

let calendar = Calendar.current

let startDate = calendar.date(from: DateComponents(year: 2010, month: 11, day: 22))!
let endDate = calendar.date(from: DateComponents(year: 2015, month: 5, day: 1))!

let dateComponents = calendar.dateComponents([Calendar.Component.day], from: startDate, to: endDate)

print(dateComponents) // prints: day: 1621 isLeapMonth: false
print(String(describing: dateComponents.day)) // prints: Optional(1621)

#2. Using DateComponentsFormatter's string(from:to:) method

import Foundation

let calendar = Calendar.current

let startDate = calendar.date(from: DateComponents(year: 2010, month: 11, day: 22))!
let endDate = calendar.date(from: DateComponents(year: 2015, month: 5, day: 1))!

let formatter = DateComponentsFormatter()
formatter.unitsStyle = .full
formatter.allowedUnits = [NSCalendar.Unit.day]

let elapsedTime = formatter.string(from: startDate, to: endDate)
print(String(describing: elapsedTime)) // prints: Optional("1,621 days")

If choosing between OAuth versions, go with OAuth 2.0.

OAuth bearer tokens should only be used with a secure transport.

OAuth bearer tokens are only as secure or insecure as the transport that encrypts the conversation. HTTPS takes care of protecting against replay attacks, so it isn't necessary for the bearer token to also guard against replay.

While it is true that if someone intercepts your bearer token they can impersonate you when calling the API, there are plenty of ways to mitigate that risk. If you give your tokens a long expiration period and expect your clients to store the tokens locally, you have a greater risk of tokens being intercepted and misused than if you give your tokens a short expiration, require clients to acquire new tokens for every session, and advise clients not to persist tokens.

If you need to secure payloads that pass through multiple participants, then you need something more than HTTPS/SSL, since HTTPS/SSL only encrypts one link of the graph. This is not a fault of OAuth.

Bearer tokens are easy to for clients to obtain, easy for clients to use for API calls and are widely used (with HTTPS) to secure public facing APIs from Google, Facebook, and many other services.

Methods on SynchronizedMap hold the lock on the object, whereas in ConcurrentHashMap there's a concept of "lock striping" where locks are held on buckets of the contents instead. Thus improved scalability and performance.

I think the accepted way is better, but I guess this might work as well

function getElementByClass(&$parentNode, $tagName, $className, $offset = 0) {
    $response = false;

    $childNodeList = $parentNode->getElementsByTagName($tagName);
    $tagCount = 0;
    for ($i = 0; $i < $childNodeList->length; $i++) {
        $temp = $childNodeList->item($i);
        if (stripos($temp->getAttribute('class'), $className) !== false) {
            if ($tagCount == $offset) {
                $response = $temp;
                break;
            }

            $tagCount++;
        }

    }

    return $response;
}

Add the following:

using System.Linq

...and call ToList() on the IQueryable<>.

One refinement to some of these answers is to let CSS do more of the work.

The basic route seems to be:

1. Create a container element to hold the textarea and a hidden div
2. Using Javascript, keep the textarea’s contents synced with the div’s
3. Let the browser do the work of calculating the height of that div
4. Because the browser handles rendering / sizing the hidden div, we avoid explicitly setting the textarea’s height.

document.addEventListener('DOMContentLoaded', () => {_x000D_
    textArea.addEventListener('change', autosize, false)_x000D_
    textArea.addEventListener('keydown', autosize, false)_x000D_
    textArea.addEventListener('keyup', autosize, false)_x000D_
    autosize()_x000D_
}, false)_x000D_
_x000D_
function autosize() {_x000D_
    // Copy textarea contents to div browser will calculate correct height_x000D_
    // of copy, which will make overall container taller, which will make_x000D_
    // textarea taller._x000D_
    textCopy.innerHTML = textArea.value.replace(/\n/g, '<br/>')_x000D_
}

$("#testID #testID2").removeClass("test2").addClass("test3");

Because you have assigned an id to img too, you can simply do this too:

$("#testID2").removeClass("test2").addClass("test3");

And finally, you can do this too:

$("#testID img").removeClass("test2").addClass("test3");

This may help you!

You could do it this way:

-- Notice how STATE got moved inside the condition:
CASE WHEN STATE = 2 AND RetailerProcessType IN (1, 2) THEN '"AUTHORISED"'
     WHEN STATE = 1 AND RetailerProcessType = 2 THEN '"PENDING"'
     ELSE '"DECLINED"'
END

The reason you can do an AND here is that you are not checking the CASE of STATE, but instead you are CASING Conditions.

The key part here is that the STATE condition is a part of the WHEN.

For disabling a button add css class disabled to it . write

$("button").addClass('disabled')

If you really need to specify all the .jar files dynamically you could use shell scripts, or Apache Ant. There's a commons project called Commons Launcher which basically lets you specify your startup script as an ant build file (if you see what I mean).

Then, you can specify something like:

<path id="base.class.path">
    <pathelement path="${resources.dir}"/>
    <fileset dir="${extensions.dir}" includes="*.jar" />
    <fileset dir="${lib.dir}" includes="*.jar"/>
</path>

In your launch build file, which will launch your application with the correct classpath.

Since Python 3.4 / PEP450 there is a statistics module in the standard library, which has a method stdev for calculating the standard deviation of iterables like yours:

>>> A_rank = [0.8, 0.4, 1.2, 3.7, 2.6, 5.8]
>>> import statistics
>>> statistics.stdev(A_rank)
2.0634114147853952

you dont have to do that in the Google chrome. Use the Internet explorer it offers the option to copy the css associated and after you copy and paste select the style and put that into another file .css to call into that html which you have created. Hope this will solve you problem than anything else:)

    android:id="@+id/i_am_id"
    android:text="my name"
    android:textSize="17sp"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="1"/>

Then, the insertion point should be a layout like LinearLayout:

res/layout/activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/aaa"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:id="@+id/insert_point"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    </LinearLayout>

</RelativeLayout>

Then the code should be

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

    LayoutInflater inflater = getLayoutInflater();
    View view = inflater.inflate(R.layout.my_view, null);
    ViewGroup main = (ViewGroup) findViewById(R.id.insert_point);
    main.addView(view, 0);
}

The reason I post this very similar answer is that when I tried to implement Mark's solution, I got stuck on what xml file should I use for insert_point and the child view. I used layout in the child view firstly and it was totally not working, which took me several hours to figure out. So hope my exploration can save others' time.

Swift 5.3:

let languagePrefix = Locale.preferredLanguages[0]
print(languagePrefix)

In the simplest case, just do

X <- read.csv(url("http://some.where.net/data/foo.csv"))

plus which ever options read.csv() may need.

Edit in Sep 2020 or 9 years later:

For a few years now R also supports directly passing the URL to read.csv:

X <- read.csv("http://some.where.net/data/foo.csv")

End of 2020 edit. Original post continutes.

Long answer: Yes this can be done and many packages have use that feature for years. E.g. the tseries packages uses exactly this feature to download stock prices from Yahoo! for almost a decade:

R> library(tseries)
Loading required package: quadprog
Loading required package: zoo

    ‘tseries’ version: 0.10-24

    ‘tseries’ is a package for time series analysis and computational finance.

    See ‘library(help="tseries")’ for details.

I couldn't always use pointer-events: none in my scenario, because I wanted both the overlay and the underlying element(s) to be clickable / selectable.

The DOM structure looked like this:

<div id="outerElement">
   <div id="canvas-wrapper">
      <canvas id="overlay"></canvas>
   </div>
   <!-- Omitted: element(s) behind canvas that should still be selectable -->
</div>

(The outerElement, canvas-wrapper and canvas elements have the same size.)

To make the elements behind the canvas act normally (e.g. selectable, editable), I used the following code:

canvasWrapper.style.pointerEvents = 'none';

outerElement.addEventListener('mousedown', event => {
    const clickedOnElementInCanvas = yourCheck // TODO: check if the event *would* click a canvas element.
    if (!clickedOnElementInCanvas) {

        // if necessary, add logic to deselect your canvas elements ...

        wrapper.style.pointerEvents = 'none';
        return true;
    }

    // Check if we emitted the event ourselves (avoid endless loop)
    if (event.isTrusted) {
        // Manually forward element to the canvas
        const mouseEvent = new MouseEvent(event.type, event);
        canvas.dispatchEvent(mouseEvent);
        mouseEvent.stopPropagation();
    }
    return true;
});

Some canvas objects also came with input fields, so I had to allow keyboard events, too. To do this, I had to update the pointerEvents property based on whether a canvas input field was currently focused or not:

onCanvasModified(canvas, () => {
    const inputFieldInCanvasActive = // TODO: Check if an input field of the canvas is active.
    wrapper.style.pointerEvents = inputFieldInCanvasActive  ? 'auto' : 'none';
});

@media queries serve this purpose. Here's an example:

@media only screen and (max-width: 991px) and (min-width: 769px){
 /* CSS that should be displayed if width is equal to or less than 991px and larger 
  than 768px goes here */
}

@media only screen and (max-width: 991px){
 /* CSS that should be displayed if width is equal to or less than 991px goes here */
}

for 1 dimensional array

int[] listItems = new int[] {2,4,8};
int length = listItems.Length;

for multidimensional array

int length = listItems.Rank;

To get the size of 1 dimension

int length =  listItems.GetLength(0);

Redirection in angularjs 4 Button for event in eg:app.home.html

 @Component({
   selector: 'app-root',
   templateUrl: './app.home.html',

 export class HomeComponant {
   title = 'Home';

This is a new feature of C# 6 called an expression bodied member that allows you to define a getter only property using a lambda like function.

While it is considered syntactic sugar for the following, they may not produce identical IL:

public int MaxHealth
{
    get
    {
        return Memory[Address].IsValid
               ?   Memory[Address].Read<int>(Offs.Life.MaxHp)
               :   0;
    }
}

It turns out that if you compile both versions of the above and compare the IL generated for each you'll see that they are NEARLY the same.

Here is the IL for the classic version in this answer when defined in a class named TestClass:

.property instance int32 MaxHealth()
{
    .get instance int32 TestClass::get_MaxHealth()
}

.method public hidebysig specialname 
    instance int32 get_MaxHealth () cil managed 
{
    // Method begins at RVA 0x2458
    // Code size 71 (0x47)
    .maxstack 2
    .locals init (
        [0] int32
    )

    IL_0043: br.s IL_0045

    IL_0045: ldloc.0
    IL_0046: ret
} // end of method TestClass::get_MaxHealth

And here is the IL for the expression bodied member version when defined in a class named TestClass:

.property instance int32 MaxHealth()
{
    .get instance int32 TestClass::get_MaxHealth()
}

.method public hidebysig specialname 
    instance int32 get_MaxHealth () cil managed

Update:

Note that expression-bodied members were expanded to include properties, constructors, finalizers and indexers in C# 7.0.

There is a file called config.inc.php in the phpmyadmin folder.

The file path is C:\wamp\apps\phpmyadmin4.0.4

Edit The auth_type 'cookie' to 'config' or 'http'

$cfg['Servers'][$i]['auth_type'] = 'cookie';

$cfg['Servers'][$i]['auth_type'] = 'config';

or

$cfg['Servers'][$i]['auth_type'] = 'http';

When you go to the phpmyadmin site then you will be asked for the username and password. This also secure external people from accessing your phpmyadmin application if you happen to have your web server exposed to outside connections.

Solution to this problem is simple

Go to build.gradle (module.app) file

It will help us to rebuild gradle for the project, to make it sync again.

Resizing the icon is not straightforward. You need to use Java's graphics 2D to scale the image. The first parameter is a Image class which you can easily get from ImageIcon class. You can use ImageIcon class to load your image file and then simply call getter method to get the image.

private Image getScaledImage(Image srcImg, int w, int h){
    BufferedImage resizedImg = new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB);
    Graphics2D g2 = resizedImg.createGraphics();

    g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
    g2.drawImage(srcImg, 0, 0, w, h, null);
    g2.dispose();

    return resizedImg;
}

group by default order by pk id,so the result
username point avg_time
demo123 100 90 ---> id = 4
demo123456 100 100 ---> id = 7
demo 90 120 ---> id = 1

A little bit off topic but useful is the pythonic numpy approach. Its robust and fast but just does compare pixels and not the objects or data the picture contains (and it requires images of same size and shape):

A very simple and fast approach to do this without openCV and any library for computer vision is to norm the picture arrays by

import numpy as np
picture1 = np.random.rand(100,100)
picture2 = np.random.rand(100,100)
picture1_norm = picture1/np.sqrt(np.sum(picture1**2))
picture2_norm = picture2/np.sqrt(np.sum(picture2**2))

After defining both normed pictures (or matrices) you can just sum over the multiplication of the pictures you like to compare:

1) If you compare similar pictures the sum will return 1:

In[1]: np.sum(picture1_norm**2)
Out[1]: 1.0

2) If they aren't similar, you'll get a value between 0 and 1 (a percentage if you multiply by 100):

In[2]: np.sum(picture2_norm*picture1_norm)
Out[2]: 0.75389941124629822

Please notice that if you have colored pictures you have to do this in all 3 dimensions or just compare a greyscaled version. I often have to compare huge amounts of pictures with arbitrary content and that's a really fast way to do so.

I used the below code to convert a string to boolean.

Convert.ToBoolean(Convert.ToInt32(myString));

There's an alternative approach to this:

#include <iterator>
#include <algorithm>

// ...

    copy(istream_iterator<int>(iFile), istream_iterator<int>(),
         ostream_iterator<int>(cerr, "\n"));

Open Command Prompt with Administrator Permissions, and repeat the command:

python -m pip install --upgrade pip

You can use the IGNORE keyword too, example:

 update IGNORE table set primary_field = 'value'...............

You cannot get this in general. From Javascript, you can only get the HTTP header, which may or may not have an IP address (typically only has the host name). Part of the browser's program is to abstract the TCP/IP address away and only allow you to deal with a host name.

Previous answers got you list of torch.Size Here is how to get list of ints

listofints = [int(x) for x in tensor.shape]

Typically, you would use a hash table and function object, both available in Boost, TR1 and C++0x.

void func1() {
}
std::unordered_map<std::string, std::function<void()>> hash_map;
hash_map["Value1"] = &func1;
// .... etc
hash_map[mystring]();

This is a little more overhead at runtime but a bajillion times more maintainable. Hash tables offer O(1) insertion, lookup, and etc, which makes them the same complexity as the assembly-style jump-table.

You can simply call your form's submit method in the onchange event of your file input.

document.getElementById("file").onchange = function() {
    document.getElementById("form").submit();
};

To change dir

foo: 
    $(MAKE) -C mydir

multi:
    $(MAKE) -C / -C my-custom-dir   ## Equivalent to /my-custom-dir

I found eot file should be put beyond ttf. If it's under ttf, thought the font shows correctly, IE9 will still throw an error.

Recommend:

@font-face {
  font-family: 'Font-Name';
  src: url('../fonts/Font-Name.eot?#iefix') format('embedded-opentype');
  src: url('../fonts/Font-Name.ttf')  format('truetype');
}

Not Recommend:

@font-face {
  font-family: 'Font-Name';
  src: url('../fonts/Font-Name.ttf')  format('truetype');
  src: url('../fonts/Font-Name.eot?#iefix') format('embedded-opentype');
  }

Updated for Bootstrap 4.1+

Bootstrap 4 the navbar now uses flexbox so the Website Name can be centered using mx-auto. The left and right side menus don't require floats.

<nav class="navbar navbar-expand-md navbar-fixed-top navbar-dark bg-dark main-nav">
    <div class="container">
        <ul class="nav navbar-nav">
            <li class="nav-item active">
                <a class="nav-link" href="#">Home</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Download</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Register</a>
            </li>
        </ul>
        <ul class="nav navbar-nav mx-auto">
            <li class="nav-item"><a class="nav-link" href="#">Website Name</a></li>
        </ul>
        <ul class="nav navbar-nav">
            <li class="nav-item">
                <a class="nav-link" href="#">Rates</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Help</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Contact</a>
            </li>
        </ul>
    </div>
</nav>

Navbar center with mx-auto Demo

If the Navbar only has a single navbar-nav, then justify-content-center can also be used to center.

EDIT

In the solution above, the Website Name is centered relative to the left and right navbar-nav so if the width of these adjacent navs are different the Website Name is no longer centered.

To resolve this, one of the flexbox workarounds for absolute centering can be used...

Option 1 - Use position:absolute;

Since it's ok to use absolute positioning in flexbox, one option is to use this on the item to be centered.

.abs-center-x {
    position: absolute;
    left: 50%;
    transform: translateX(-50%);
}

Navbar center with absolute position Demo

Option 2 - Use flexbox nesting

Finally, another option is to make the centered item also display:flexbox (using d-flex) and center justified. In this case each navbar component must have flex-grow:1

As of Bootstrap 4 Beta, the Navbar is now display:flex. Bootstrap 4.1.0 includes a new flex-fill class to make each nav section fill the width:

<nav class="navbar navbar-expand-sm navbar-dark bg-dark main-nav">
    <div class="container justify-content-center">
        <ul class="nav navbar-nav flex-fill w-100 flex-nowrap">
            <li class="nav-item active">
                <a class="nav-link" href="#">Home</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Download</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Register</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">More</a>
            </li>
        </ul>
        <ul class="nav navbar-nav flex-fill justify-content-center">
            <li class="nav-item"><a class="nav-link" href="#">Center</a></li>
        </ul>
        <ul class="nav navbar-nav flex-fill w-100 justify-content-end">
            <li class="nav-item">
                <a class="nav-link" href="#">Help</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Contact</a>
            </li>
        </ul>
    </div>
</nav>

Navbar center with flexbox nesting Demo

Prior to Bootstrap 4.1.0 you can add the flex-fill class like this...

.flex-fill {
   flex:1
}

As of 4.1 flex-fill is included in Bootstrap.

1. Open the project explorer ( default left side )
2. Click on the tiny wheel setting button
3. Mark Auto scroll from source option.

Boom! You are done.

Maybe you need a sorted list anyway?

Try this:

your_list = [13, 352, 2553, 0.5, 89, 0.4]
sorted_list = sorted(your_list)
index_of_higher_value = your_list.index(sorted_list[-1])

Suppose you want to insert a particular line of text (not an empty line):

@echo off
FOR /F %%C IN ('FIND /C /V "" ^<%origfile%') DO SET totallines=%%C
set /a totallines+=1

@echo off
<%origfile% (FOR /L %%i IN (1,1,%totallines%) DO (
  SETLOCAL EnableDelayedExpansion
  SET /p L=
  IF %%i==%insertat% ECHO(!TL!
  ECHO(!L!
  ENDLOCAL
)
) >%tempfile%

COPY /Y %tempfile% %origfile% >NUL

"tty" originally meant "teletype" and "pty" means "pseudo-teletype".

In UNIX, /dev/tty* is any device that acts like a "teletype", ie, a terminal. (Called teletype because that's what we had for terminals in those benighted days.)

A pty is a pseudotty, a device entry that acts like a terminal to the process reading and writing there, but is managed by something else. They first appeared (as I recall) for X Window and screen and the like, where you needed something that acted like a terminal but could be used from another program.

Assuming you are using ssh to connect rsync, what about to send a ssh command before:

ssh user@server mkdir -p existingdir/newdir

if it already exists, nothing happens

If you support IE, for versions of Internet Explorer 8 and above, this:

<meta http-equiv="X-UA-Compatible" content="IE=9; IE=8; IE=7" />

Forces the browser to render as that particular version's standards. It is not supported for IE7 and below.

If you separate with semi-colon, it sets compatibility levels for different versions. For example:

<meta http-equiv="X-UA-Compatible" content="IE=7; IE=9" />

Renders IE7 and IE8 as IE7, but IE9 as IE9. It allows for different levels of backwards compatibility. In real life, though, you should only chose one of the options:

<meta http-equiv="X-UA-Compatible" content="IE=8" />

This allows for much easier testing and maintenance. Although generally the more useful version of this is using Emulate:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />

For this:

<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

It forces the browser the render at whatever the most recent version's standards are.

For more information, there is plenty to read about on MSDN,

Try this setup:

a = [["a","b","c",],["d","e"],["f","g","h"]]

To print the 2nd element in the 1st list ("b"), use print a[0][1] - For the 2nd element in 3rd list ("g"): print a[2][1]

The first brackets reference which nested list you're accessing, the second pair references the item in that list.

Use the command dir to list all the directories and files in a directory; ls is a unix command.

<p>tetxetextex</p>
<ol><li>first element</li></ol>
<p>other textetxeettx</p>

Because both <p> and <ol> are element rendered as block.

Windows type command works similarly to UNIX cat.

Example 1: Merge with file names (This will merge file1.csv & file2.csv to create concat.csv)

type file1.csv file2.csv > concat.csv

Example 2: Merge files with pattern (This will merge all files with csv extension and create concat.csv)

When using asterisk(*) to concatenate all files. Please DON'T use same extension for target file(Eg. .csv). There should be some difference in pattern else target file will also be considered in concatenation

type  *.csv > concat_csv.txt

I find the easiest way of doing this is with percentages and just allowing the margin to tally up your width

This means you end up with something like this if you where using your example

#box {
   display: flex;
}

.item {
   flex: 1 1 23%;
   margin: 0 1%;
}

Does mean your values are based on the width though which might not be good for everybody.

In Eclipse Folder there is eclipse.ini file. Increase size -Xms512m -Xmx1024m

The listFiles method, with or without a filter does not guarantee any order.

It does, however, return an array, which you can sort with Arrays.sort().

File[] files = XMLDirectory.listFiles(filter_xml_files);
Arrays.sort(files);
for(File _xml_file : files) {
    ...
}

This works because File is a comparable class, which by default sorts pathnames lexicographically. If you want to sort them differently, you can define your own comparator.

If you prefer using Streams:

A more modern approach is the following. To print the names of all files in a given directory, in alphabetical order, do:

Files.list(Paths.get(dirName)).sorted().forEach(System.out::println)

Replace the System.out::println with whatever you want to do with the file names. If you want only filenames that end with "xml" just do:

Files.list(Paths.get(dirName))
    .filter(s -> s.toString().endsWith(".xml"))
    .sorted()
    .forEach(System.out::println)

Again, replace the printing with whichever processing operation you would like.

Instead of playing with tags, I took different approach. Made delegate for my subclass of UITableViewCell(OptionButtonsCell) and added an indexPath var. From my button in storyboard I connected @IBAction to the OptionButtonsCell and there I send delegate method with the right indexPath to anyone interested. In cell for index path I set current indexPath and it works :)

Let the code speak for itself:

Swift 3 Xcode 8

OptionButtonsTableViewCell.swift

import UIKit
protocol OptionButtonsDelegate{
    func closeFriendsTapped(at index:IndexPath)
}
class OptionButtonsTableViewCell: UITableViewCell {
    var delegate:OptionButtonsDelegate!
    @IBOutlet weak var closeFriendsBtn: UIButton!
    var indexPath:IndexPath!
    @IBAction func closeFriendsAction(_ sender: UIButton) {
        self.delegate?.closeFriendsTapped(at: indexPath)
    }
}

MyTableViewController.swift

class MyTableViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, OptionButtonsDelegate {...

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "optionCell") as! OptionButtonsTableViewCell
    cell.delegate = self
    cell.indexPath = indexPath
    return cell   
}

func closeFriendsTapped(at index: IndexPath) {
     print("button tapped at index:\(index)")
}

Boostrap 3 has a component for exactly this. It's:

<span class="badge">100</span>

Considering the exact question, putting us in a "special" coordinates system where positive axis means moving DOWN (like a screen or an interface view), you need to adapt this function like this, and negative the Y coordinates:

Example in Swift 2.0

func angle_between_two_points(pa:CGPoint,pb:CGPoint)->Double{
    let deltaY:Double = (Double(-pb.y) - Double(-pa.y))
    let deltaX:Double = (Double(pb.x) - Double(pa.x))
    var a = atan2(deltaY,deltaX)
    while a < 0.0 {
        a = a + M_PI*2
    }
    return a
}

This function gives a correct answer to the question. Answer is in radians, so the usage, to view angles in degrees, is:

let p1 = CGPoint(x: 1.5, y: 2) //estimated coords of p1 in question
let p2 = CGPoint(x: 2, y : 3) //estimated coords of p2 in question

print(angle_between_two_points(p1, pb: p2) / (M_PI/180))
//returns 296.56

Please use --user at end of this, it is working fine for me.

pip install enum34 --user

using System.Diagnostics;

class Program

    static void Main()
    {
        Process.Start("C:\\");

If your application needs cmd arguments, use something like this:

using System.Diagnostics;

class Program
{
    static void Main()
    {
        LaunchCommandLineApp();
    }

    /// <summary>
    /// Launch the application with some options set.
    /// </summary>
    static void LaunchCommandLineApp()
    {
        // For the example
        const string ex1 = "C:\\";
        const string ex2 = "C:\\Dir";

        // Use ProcessStartInfo class
        ProcessStartInfo startInfo = new ProcessStartInfo();
        startInfo.CreateNoWindow = false;
        startInfo.UseShellExecute = false;
        startInfo.FileName = "dcm2jpg.exe";
        startInfo.WindowStyle = ProcessWindowStyle.Hidden;
        startInfo.Arguments = "-f j -o \"" + ex1 + "\" -z 1.0 -s y " + ex2;

        try
        {
            // Start the process with the info we specified.
            // Call WaitForExit and then the using statement will close.
            using (Process exeProcess = Process.Start(startInfo))
            {
                exeProcess.WaitForExit();
            }
        }
        catch
        {
             // Log error.
        }
    }
}

My problem was that my company proxy was getting in the way. The solution here was to identify the Root CA / certificate chain of our proxy, (on mac) export it from the keychain in .pem format, then export a variable for node to use.

export NODE_EXTRA_CA_CERTS=/path/to/your/CA/cert.pem

Use git push origin master instead.

You have a repository locally and the initial git push is "pushing" to it. It's not necessary to do so (as it is local) and it shows everything as up-to-date. git push origin master specifies a a remote repository (origin) and the branch located there (master).

For more information, check out this resource.

Another way to do this would be to add this line to the assembly info of the web application:

// Configure log4net using the .config file
[assembly: log4net.Config.XmlConfigurator(Watch = true)]

Similar to Shriek's.

I faced this issue Many time from different scenarios

one of them when I tryed Connecting to team foundation server for different Logged User

so the solution is easy Just Click Switch User

hope this help you

git pull origin master

this will sync your master to the central repo and if new branches are pushed to the central repo it will also update your clone copy.

I know that are already many answers written for this solution however I want to show another javascript method (dependent on JQuery) in which you simply need to include ONLY a single JS File without any dependency on CSS or Gif Images in your code and that will take care of all progress bar related animations that happens during Ajax Request. You need to simnply pass javascript function like this

var objGlobalEvent = new RegisterGlobalEvents(true, "");

I have tried other ways they are not right. This one works.

My inquiry is this. When does one use #import and when does one use @class?

Simple answer: You #import or #include when there is a physical dependency. Otherwise, you use forward declarations (@class MONClass, struct MONStruct, @protocol MONProtocol).

Here are some common examples of physical dependence:

• Any C or C++ value (a pointer or reference is not a physical dependency). If you have a CGPoint as an ivar or property, the compiler will need to see the declaration of CGPoint.
• Your superclass.
• A method you use.

Sometimes if I use a @class declaration, I see a common compiler warning such as the following: "warning: receiver 'FooController' is a forward class and corresponding @interface may not exist."

The compiler's actually very lenient in this regard. It will drop hints (such as the one above), but you can trash your stack easily if you ignore them and don't #import properly. Although it should (IMO), the compiler does not enforce this. In ARC, the compiler is more strict because it is responsible for reference counting. What happens is the compiler falls back on a default when it encounters an unknown method which you call. Every return value and parameter is assumed to be id. Thus, you ought to eradicate every warning from your codebases because this should be considered physical dependence. This is analogous to calling a C function which is not declared. With C, parameters are assumed to be int.

The reason you would favor forward declarations is that you can reduce your build times by factors because there is minimal dependence. With forward declarations, the compiler sees there is a name, and can correctly parse and compile the program without seeing the class declaration or all of its dependencies when there is no physical dependency. Clean builds take less time. Incremental builds take less time. Sure, you will end up spending a little more time making sure the all the headers you need are visible to every translation as a consequence, but this pays off in reduced build times quickly (assuming your project is not tiny).

If you use #import or #include instead, you're throwing a lot more work at the compiler than is necessary. You're also introducing complex header dependencies. You can liken this to a brute-force algorithm. When you #import, you're dragging in tons of unnecessary information, which requires a lot of memory, disk I/O, and CPU to parse and compile the sources.

ObjC is pretty close to ideal for a C based language with regards to dependency because NSObject types are never values -- NSObject types are always reference counted pointers. So you can get away with incredibly fast compile times if you structure your program's dependencies appropriately and forward where possible because there is very little physical dependence required. You can also declare properties in the class extensions to further minimize dependence. That's a huge bonus for large systems -- you would know the difference it makes if you have ever developed a large C++ codebase.

Therefore, my recommendation is to use forwards where possible, and then to #import where there is physical dependence. If you see the warning or another which implies physical dependence -- fix them all. The fix is to #import in your implementation file.

As you build libraries, you will likely classify some interfaces as a group, in which case you would #import that library where physical dependence is introduced (e.g. #import <AppKit/AppKit.h>). This can introduce dependence, but the library maintainers can often handle the physical dependencies for you as needed -- if they introduce a feature, they can minimize the impact it has on your builds.

For ICS I´ve implemented your code and made a class that extends AsyncTask. I hope you appreciate it! Thanks for your code and solution.

public class UpdateApp extends AsyncTask<String,Void,Void>{
    private Context context;
    public void setContext(Context contextf){
        context = contextf;
    }

    @Override
    protected Void doInBackground(String... arg0) {
        try {
            URL url = new URL(arg0[0]);
            HttpURLConnection c = (HttpURLConnection) url.openConnection();
            c.setRequestMethod("GET");
            c.setDoOutput(true);
            c.connect();

            String PATH = "/mnt/sdcard/Download/";
            File file = new File(PATH);
            file.mkdirs();
            File outputFile = new File(file, "update.apk");
            if(outputFile.exists()){
                outputFile.delete();
            }
            FileOutputStream fos = new FileOutputStream(outputFile);

            InputStream is = c.getInputStream();

            byte[] buffer = new byte[1024];
            int len1 = 0;
            while ((len1 = is.read(buffer)) != -1) {
                fos.write(buffer, 0, len1);
            }
            fos.close();
            is.close();

            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.fromFile(new File("/mnt/sdcard/Download/update.apk")), "application/vnd.android.package-archive");
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // without this flag android returned a intent error!
            context.startActivity(intent);


        } catch (Exception e) {
            Log.e("UpdateAPP", "Update error! " + e.getMessage());
        }
        return null;
    }
}   

To use it, in your main activity call by this way:

atualizaApp = new UpdateApp();
atualizaApp.setContext(getApplicationContext());
atualizaApp.execute("http://serverurl/appfile.apk");

it should. Typically that's how you do multiple selectors. Otherwise it may not like you trying to assign the return values of three uploads to the same var.

I would suggest using .each or maybe push the returns to an array rather than assigning them to that value.

Instead of using --no-optional every single time, we can just add it to npm or yarn config.

For Yarn, there is a default no-optional config, so we can just edit that:

yarn config set ignore-optional true

For npm, there is no default config set, so we can create one:

npm config set ignore-optional true

It's a linker error. ld is the linker, so if you get an error message ending with "ld returned 1 exit status", that tells you that it's a linker error.

The error message tells you that none of the object files you're linking against contains a definition for avergecolumns. The reason for that is that the function you've defined is called averagecolumns (in other words: you misspelled the function name when calling the function (and presumably in the header file as well - otherwise you'd have gotten a different error at compile time)).

This *& in theory as well as in practical its possible and called as reference to pointer variable. and it's act like same. This *& combination is used in as function parameter for 'pass by' type defining. unlike ** can also be used for declaring a double pointer variable.
The passing of parameter is divided into pass by value, pass by reference, pass by pointer. there are various answer about "pass by" types available. however the basic we require to understand for this topic is.

pass by reference --> generally operates on already created variable refereed while passing to function e.g fun(int &a);

pass by pointer --> Operates on already initialized 'pointer variable/variable address' passing to function e.g fun(int* a);

auto addControl = [](SomeLabel** label, SomeControl** control) {
    *label = new SomeLabel;
    *control = new SomeControl;
    // few more operation further.
};

addControl(&m_label1,&m_control1);
addControl(&m_label2,&m_control2);
addControl(&m_label3,&m_control3);

in the above example(this is the real life problem i came across) i am trying to init few pointer variable from the lambda function and for that we need to pass it by double pointer, so that comes with d-referencing of pointer for its all usage inside of that lambda + while passing pointer in function which takes double pointer, you need to pass reference to the pointer variable.

so with this same thing reference to the pointer variable, *& this combination helps. in below given way for the same example i have mentioned above.

auto addControl = [](SomeLabel*& label, SomeControl*& control) {
        label = new SomeLabel;
        control = new SomeControl;
        // few more operation further.
    };

addControl(m_label1,m_control1);
addControl(m_label2,m_control2);
addControl(m_label3,m_control3);

so here you can see that you neither require d-referencing nor we require to pass reference to pointer variable while passing in function, as current pass by type is already reference to pointer.

Hope this helps :-)

I had the same problem after I used the .gitignore file from https://github.com/github/gitignore/blob/master/Rails.gitignore

The folder is part of the URL you set when you create request: "ftp://www.contoso.com/test.htm". If you use "ftp://www.contoso.com/wibble/test.htm" then the file will be uploaded to a folder named wibble.

You may need to first use a request with Method = WebRequestMethods.Ftp.MakeDirectory to make the wibble folder if it doesn't already exist.

You can still use the ExcelFile class (and the sheet_names attribute):

xl = pd.ExcelFile('foo.xls')

xl.sheet_names  # see all sheet names

xl.parse(sheet_name)  # read a specific sheet to DataFrame

see docs for parse for more options...

I believe that you will have to drop the foreign key constraints first. Then update all of the appropriate tables and remap them as they were.

ALTER TABLE [dbo.Details_tbl] DROP CONSTRAINT [FK_Details_tbl_User_tbl];
-- Perform more appropriate alters
ALTER TABLE [dbo.Details_tbl] ADD FOREIGN KEY (FK_Details_tbl_User_tbl) 
    REFERENCES User_tbl(appId);
-- Perform all appropriate alters to bring the key constraints back

However, unless memory is a really big issue, I would keep the identity as an INT. Unless you are 100% positive that your keys will never grow past the TINYINT restraints. Just a word of caution :)

Active Directory does not store the group membership on user objects. It only stores the Member list on the group. The tools show the group membership on user objects by doing queries for it.

How about:

(&(objectClass=group)(member=cn=my,ou=full,dc=domain))

(You forgot the (& ) bit in your example in the question as well).

Script its left and top properties as the number of pixels from the left edge and top edge respectively. It must have position: absolute;

var d = document.getElementById('yourDivId');
d.style.position = "absolute";
d.style.left = x_pos+'px';
d.style.top = y_pos+'px';

Or do it as a function so you can attach it to an event like onmousedown

function placeDiv(x_pos, y_pos) {
  var d = document.getElementById('yourDivId');
  d.style.position = "absolute";
  d.style.left = x_pos+'px';
  d.style.top = y_pos+'px';
}

Currently a git replace might do the trick.

In detail: Create a temporary work branch

git checkout -b temp

Reset to the commit to replace

git reset --hard <sha1>

Amend the commit with the right message

git commit --amend -m "<right message>"

Replace the old commit with the new one

git replace <old commit sha1> <new commit sha1>

go back to the branch where you were

git checkout <branch>

remove temp branch

git branch -D temp

push

guess

done.

I can give you an ok solution and you can go with it, but before I do I'm going to try to explain why Document is not a DependencyProperty to begin with.

During the lifetime of a RichTextBox control, the Document property generally doesn't change. The RichTextBox is initialized with a FlowDocument. That document is displayed, can be edited and mangled in many ways, but the underlying value of the Document property remains that one instance of the FlowDocument. Therefore, there is really no reason it should be a DependencyProperty, ie, Bindable. If you have multiple locations that reference this FlowDocument, you only need the reference once. Since it is the same instance everywhere, the changes will be accessible to everyone.

I don't think FlowDocument supports document change notifications, though I am not sure.

That being said, here's a solution. Before you start, since RichTextBox doesn't implement INotifyPropertyChanged and Document is not a DependencyProperty, we have no notifications when the RichTextBox's Document property changes, so the binding can only be OneWay.

Create a class that will provide the FlowDocument. Binding requires the existence of a DependencyProperty, so this class inherits from DependencyObject.

class HasDocument : DependencyObject
{
    public static readonly DependencyProperty DocumentProperty =
        DependencyProperty.Register("Document", 
                                    typeof(FlowDocument), 
                                    typeof(HasDocument), 
                                    new PropertyMetadata(new PropertyChangedCallback(DocumentChanged)));

    private static void DocumentChanged(DependencyObject obj, DependencyPropertyChangedEventArgs e)
    {
        Debug.WriteLine("Document has changed");
    }

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

Create a Window with a rich text box in XAML.

<Window x:Class="samples.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Flow Document Binding" Height="300" Width="300"
    >
    <Grid>
      <RichTextBox Name="richTextBox" />
    </Grid>
</Window>

Give the Window a field of type HasDocument.

HasDocument hasDocument;

Window constructor should create the binding.

hasDocument = new HasDocument();

InitializeComponent();

Binding b = new Binding("Document");
b.Source = richTextBox;
b.Mode = BindingMode.OneWay;
BindingOperations.SetBinding(hasDocument, HasDocument.DocumentProperty, b);

If you want to be able to declare the binding in XAML, you would have to make your HasDocument class derive from FrameworkElement so that it can be inserted into the logical tree.

Now, if you were to change the Document property on HasDocument, the rich text box's Document will also change.

FlowDocument d = new FlowDocument();
Paragraph g = new Paragraph();
Run a = new Run();
a.Text = "I showed this using a binding";
g.Inlines.Add(a);
d.Blocks.Add(g);

hasDocument.Document = d;

You can do a port redirect. This is what I do for a Silverlight policy server running on a Linux box

I change the line "pod 'Alamofire', '~> 4.0'" to "pod 'Alamofire', :git => 'https://github.com/Alamofire/Alamofire', :commit => '3cc5b4e'" after that in terminal: "pod install --repo-update" and it works.

The proposed solution is just to much work for something that can be done like this:

Get-Alias -Definition Write*

It is also now possible to use OCaml for developing iOS applications. It is not part of the standard distribution and requires modifications provided by the Psellos company. See here for more information: http://psellos.com/ocaml/.

As mentioned in the top ranked post, the following works with the Sizzle engine.

$('input:text[value=""]');

In the comments, it was noted that removing the :text portion of the selector causes the selector to fail. I believe what's happening is that Sizzle actually relies on the browser's built in selector engine when possible. When :text is added to the selector, it becomes a non-standard CSS selector and thereby must needs be handled by Sizzle itself. This means that Sizzle checks the current value of the INPUT, instead of the "value" attribute specified in the source HTML.

So it's a clever way to check for empty text fields, but I think it relies on a behavior specific to the Sizzle engine (that of using the current value of the INPUT instead of the attribute defined in the source code). While Sizzle might return elements that match this selector, document.querySelectorAll will only return elements that have value="" in the HTML. Caveat emptor.

I was using the TextField flutter control.I got the user typed input using below methods.

onChanged:(value){
}

OpenCV can be compiled with FFMPEG support. From ./configure --help:

--with-ffmpeg     use ffmpeg libraries (see LICENSE) [automatic]

You can then use cvCreateFileCapture_FFMPEG to create a CvCapture with e.g. the URL of the camera's MJPG stream.

I use this to grab frames from an AXIS camera:

CvCapture *capture = 
    cvCreateFileCapture_FFMPEG("http://axis-cam/mjpg/video.mjpg?resolution=640x480&req_fps=10&.mjpg");

If you decide to learn both (and as other people have mentioned, there's no explicit need to learn both), learn C first. Going from C to C++ feels like a natural progression; going the other way feels like deliberately tying one hand behind your back. :-)

Unirest is the best library I've come across for making HTTP requests from Node. It's aiming at being a multiplatform framework, so learning how it works on Node will serve you well if you need to use an HTTP client on Ruby, PHP, Java, Python, Objective C, .Net or Windows 8 as well. As far as I can tell the unirest libraries are mostly backed by existing HTTP clients (e.g. on Java, the Apache HTTP client, on Node, Mikeal's Request libary) - Unirest just puts a nicer API on top.

Here are a couple of code examples for Node.js:

var unirest = require('unirest')

// GET a resource
unirest.get('http://httpbin.org/get')
  .query({'foo': 'bar'})
  .query({'stack': 'overflow'})
  .end(function(res) {
    if (res.error) {
      console.log('GET error', res.error)
    } else {
      console.log('GET response', res.body)
    }
  })

// POST a form with an attached file
unirest.post('http://httpbin.org/post')
  .field('foo', 'bar')
  .field('stack', 'overflow')
  .attach('myfile', 'examples.js')
  .end(function(res) {
    if (res.error) {
      console.log('POST error', res.error)
    } else {
      console.log('POST response', res.body)
    }
  })

You can jump straight to the Node docs here

$(document).ready(function() {
    $('#div2').hide(0);
    $('#preview').on('click', function() {
        $('#div1').hide(300, function() { // first hide div1
            // then show div2
            $('#div2').show(300);
        });     
    });
});

You missed # before div2

Working Sample

I am currently using PDFBox which has good support for graphic output. There is good support for extracting the vector strokes and also for managing fonts. There are some good tools for trying it out (e.g. PDFReader will display as Java Graphics2D). You can intercept the graphics tool with an SVG tool like Batik (I do this and it gives good capture).

There is no simple way to convert all PDF to SVG - it depends on the strategy and tools used to create the PDFs. Some text is converted to vectors and cannot be easily reconstructed - you have to install vector fonts and look them up.

UPDATE: I have now developed this into a package PDF2SVG which does not use Batik any more:

which has been tested on a range of PDFs. It produces SVG output consisting of

• characters as one <svg:text> per character
• paths as <svg:path>
• images as <svg:image>

Later packages will (hopefully) convert the characters to running text and the paths to higher-level graphics objects

UPDATE: We can now re-create running text from the SVG characters. We've also converted diagrams to domain-specific XML (e.g. chemical spectra). See https://bitbucket.org/petermr/svg2xml-dev. It's still in Alpha, but is moving at a useful speed. Anyone can join in!

UPDATE. (@Tim Kelty) We are continuing to work on PDF2SVG and also downstream tools that do (limited) Java OCR and creation of higher-level graphics primitives (arrows, boxes, etc.) See https://bitbucket.org/petermr/imageanalysis https://bitbucket.org/petermr/diagramanalyzer https://bitbucket.org/petermr/norma and https://bitbucket.org/petermr/ami-core . This is a funded project to capture 100 million facts from the scientific literature (contentmine.org) much of which is PDF.

I had the same problem. I'm using DB2. What I have done is a bit not too professional solution, but it works in every DBMS:

1. Add a column with the same definition without the unique contraint.
2. Copy the values from the original column to the new
3. Drop the original column (so DBMS will remove the constraint as well no matter what its name was)
4. And finally rename the new one to the original
5. And a reorg at the end (only in DB2)

ALTER TABLE USERS ADD COLUMN LOGIN_OLD VARCHAR(50) NOT NULL DEFAULT '';
UPDATE USERS SET LOGIN_OLD=LOGIN;
ALTER TABLE USERS DROP COLUMN LOGIN;
ALTER TABLE USERS RENAME COLUMN LOGIN_OLD TO LOGIN;

CALL SYSPROC.ADMIN_CMD('REORG TABLE USERS');

The syntax of the ALTER commands may be different in other DBMS

Try this:

DateTime.Now.ToString("yyyy-MM-ddThh:mm:sszzz");

zzz is the timezone offset.

That's because you missed ELSE.

"Returns the result for the first condition that is true. If there was no matching result value, the result after ELSE is returned, or NULL if there is no ELSE part." (http://dev.mysql.com/doc/refman/5.0/en/control-flow-functions.html#operator_case)

Python and just about every other computer language use the same principles as (I hope) you would use when finding a word in a printed dictionary:

(1) Depending on the human language involved, you have a notion of character ordering: 'a' < 'b' < 'c' etc

(2) First character has more weight than second character: 'az' < 'za' (whether the language is written left-to-right or right-to-left or boustrophedon is quite irrelevant)

(3) If you run out of characters to test, the shorter string is less than the longer string: 'foo' < 'food'

Typically, in a computer language the "notion of character ordering" is rather primitive: each character has a human-language-independent number ord(character) and characters are compared and sorted using that number. Often that ordering is not appropriate to the human language of the user, and then you need to get into "collating", a fun topic.

Abstract your initialization into a method, and call the method from mounted and wherever else you want.

new Vue({
  methods:{
    init(){
      //call API
      //Setup game
    }
  },
  mounted(){
    this.init()
  }
})

Then possibly have a button in your template to start over.

<button v-if="playerWon" @click="init">Play Again</button>

In this button, playerWon represents a boolean value in your data that you would set when the player wins the game so the button appears. You would set it back to false in init.

Put this at the top of your .py file (for python 2.x)

#!/usr/bin/env python 

or for python 3.x

#!/usr/bin/env python3

This should look up the python environment, without it, it will execute the code as if it were not python code, but straight to the CLI. If you need to specify a manual location of python environment put

#!/#path/#to/#python

consider using

df['column name'].astype('Int64')

nan will be changed to NaN

With this

npm install --save core-js@^3

you now get the error

"core-js@<3 is no longer maintained and not recommended for usage due to the number of
issues. Please, upgrade your dependencies to the actual version of core-js@3"

so you might want to instead try

npm install --save core-js@3

I've posted about vertical alignment it in cross-browser way (Vertically center multiple boxes with CSS)

Create one-cell table. Only table has cross-browser vertical-align

    this.reset();
 }); 
}

Chengs's answer is correct, howewer according to the admin docs not every admin template can be overwritten this way: https://docs.djangoproject.com/en/1.9/ref/contrib/admin/#overriding-admin-templates

Templates which may be overridden per app or model

Not every template in contrib/admin/templates/admin may be overridden per app or per model. The following can:

app_index.html
change_form.html
change_list.html
delete_confirmation.html
object_history.html

For those templates that cannot be overridden in this way, you may still override them for your entire project. Just place the new version in your templates/admin directory. This is particularly useful to create custom 404 and 500 pages

I had to overwrite the login.html of the admin and therefore had to put the overwritten template in this folder structure:

your_project
 |-- your_project/
 |-- myapp/
 |-- templates/
      |-- admin/
          |-- login.html  <- do not misspell this

(without the myapp subfolder in the admin) I do not have enough repution for commenting on Cheng's post this is why I had to write this as new answer.

Can't be done natively with VBA. VBA is built in a single-threaded apartment. The only way to get multiple threads is to build a DLL in something other than VBA that has a COM interface and call it from VBA.

INFO: Descriptions and Workings of OLE Threading Models

Try the following:

 for i in {1..600}; do echo wget http://example.com/search/link$(($i % 5)); done

The $(( )) syntax does an arithmetic evaluation of the contents.

For char or short to int, you just need to assign the value.

char ch = 16;
int in = ch;

Same to int64.

long long lo = ch;

All values will be 16.

In case you want to:

• also get the values for the keys
• check more than one dictonary

then:

from operator import itemgetter
foo = {'foo':1,'zip':2,'zam':3,'bar':4}
keys = ("foo","bar") 
getter = itemgetter(*keys) # returns all values
try:
    values = getter(foo)
except KeyError:
    # not both keys exist
    pass

This is what I used for Excel 2003:

Dictionary<string, string> props = new Dictionary<string, string>();
props["Provider"] = "Microsoft.Jet.OLEDB.4.0";
props["Data Source"] = repFile;
props["Extended Properties"] = "Excel 8.0";

StringBuilder sb = new StringBuilder();
foreach (KeyValuePair<string, string> prop in props)
{
    sb.Append(prop.Key);
    sb.Append('=');
    sb.Append(prop.Value);
    sb.Append(';');
}
string properties = sb.ToString();

using (OleDbConnection conn = new OleDbConnection(properties))
{
    conn.Open();
    DataSet ds = new DataSet();
    string columns = String.Join(",", columnNames.ToArray());
    using (OleDbDataAdapter da = new OleDbDataAdapter(
        "SELECT " + columns + " FROM [" + worksheet + "$]", conn))
    {
        DataTable dt = new DataTable(tableName);
        da.Fill(dt);
        ds.Tables.Add(dt);
    }
}

If you can avoid the need for concurrent writes to a single file, it sounds like you do not need a database to store the chat messages.

Just append the conversation to a text file (1 file per user\conversation). and have a directory/ file structure

Here's a simplified view of the file structure:

chat-1-bob.txt
        201101011029, hi
        201101011030, fine thanks.

chat-1-jen.txt
        201101011030, how are you?
        201101011035, have you spoken to bill recently?

chat-2-bob.txt
        201101021200, hi
        201101021222, about 12:22
chat-2-bill.txt
        201101021201, Hey Bob,
        201101021203, what time do you call this?

You would then only need to store the userid, conversation id (guid ?) & a reference to the file name.

I think you will find it hard to get a more simple scaleable solution.

You can use LOAD_FILE to get the data too see: http://dev.mysql.com/doc/refman/5.0/en/string-functions.html

If you have a requirement to rebuild a conversation you will need to put a value (date time) alongside your sent chat message (in the file) to allow you to merge & sort the files, but at this point it is probably a good idea to consider using a database.

md-icons aren't in the bower release of angular-material yet. I've been using Polymer's icons, they'll probably be the same anyway.

bower install polymer/core-icons

Just use a timeout to make your call; the timeout will be called when the event stack is finished (i.e. after the default event is called)

$("body").on('keydown', 'input[type=tel]', function (e) {
    setTimeout(() => {
        formatPhone(e)
    }, 0)
});

Since Ruby 2.5, it's really easy with SecureRandom.alphanumeric:

len = 8
SecureRandom.alphanumeric(len)
=> "larHSsgL"

It generates random strings containing A-Z, a-z and 0-9 and therefore should be applicable in most use-cases. And they are generated randomly secure, which might be a benefit, too.

This is a benchmark to compare it with the solution having the most upvotes:

require 'benchmark'
require 'securerandom'

len = 10
n = 100_000

Benchmark.bm(12) do |x|
  x.report('SecureRandom') { n.times { SecureRandom.alphanumeric(len) } }
  x.report('rand') do
    o = [('a'..'z'), ('A'..'Z'), (0..9)].map(&:to_a).flatten
    n.times { (0...len).map { o[rand(o.length)] }.join }
  end
end

                   user     system      total        real
SecureRandom   0.429442   0.002746   0.432188 (  0.432705)
rand           0.306650   0.000716   0.307366 (  0.307745)

So the rand solution only takes about 3/4 of the time of SecureRandom. That might matter if you generate a lot of strings, but if you just create some random string from time to time I'd always go with the more secure implementation since it is also easier to call and more explicit.

There is a simpler way actually. I just found:

import matplotlib.pyplot as plt
# We prepare the plot  
fig, ax = plt.subplots()

# We change the fontsize of minor ticks label 
ax.tick_params(axis='both', which='major', labelsize=10)
ax.tick_params(axis='both', which='minor', labelsize=8)

This only answers to the size of label part of your question though.

Author of the Dart Code plugin here! From the screenshot, I would say this is because your flutter project is in a sub-folder of the folder open in Code. We only scan the opened-folder to check whether it's a Flutter project - which then changes the SDK we launch and also enables the Flutter functionality (like the daemon and debugger).

You should re-open the "todo" folder directly.

If you want to have multiple projects open together, use multi-root workspaces, since Dart Code is multi-root-aware and will check each of the folders in the workspace when deciding if it needs to enable Flutter functionality.

Update

This case should be better supported in the Dart plugin now, so opening the immediate parent folder of a Flutter project should work as expected.

Also struggled with this issue, trying to upload .csv data into AWS RDS instance from my local machine using MySQL Workbench on Windows.

The addition I needed was adding OPT_LOCAL_INFILE=1 in: Connection > Advanced > Others. Note CAPS was required.

I found this answer by PeterMag in AWS Developer Forums.

For further info:

SHOW VARIABLES LIKE 'local_infile'; already returned ON and the query was:

LOAD DATA LOCAL INFILE 'filepath/file.csv' 
    INTO TABLE `table_name`
    FIELDS TERMINATED BY ',' 
    ENCLOSED BY '"'
    LINES TERMINATED BY '\n'
    IGNORE 1 ROWS;

Copying from the answer source referenced above:

Apparently this is a bug in MYSQL Workbench V8.X. In addition to the configurations shown earlier in this thread, you also need to change the MYSQL Connection in Workbench as follows:

1. Go to the Welcome page of MYSQL which displays all your connections
2. Select Manage Server Connections (the little spanner icon)
3. Select your connection
4. Select Advanced tab
5. In the Others box, add OPT_LOCAL_INFILE=1

Now I can use the LOAD DATA LOCAL INFILE query on MYSQL RDS. It seems that the File_priv permission is not required.*

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

Set the window start style as maximized. Then, hide the minimize and maximize buttons.

Here's an example

// in the service
getVehicles(){
    return Observable.interval(2200).map(i=> [{name: 'car 1'},{name: 'car 2'}])
}

// in the controller
vehicles: Observable<Array<any>>
ngOnInit() {
    this.vehicles = this._vehicleService.getVehicles();
}

// in template
<div *ngFor='let vehicle of vehicles | async'>
    {{vehicle.name}}
</div>

You can also use the shell Path APIs PathFindFileName, PathRemoveExtension. Probably worse than _splitpath for this particular problem, but those APIs are very useful for all kinds of path parsing jobs and they take UNC paths, forward slashes and other weird stuff into account.

wstring filename = L"C:\\MyDirectory\\MyFile.bat";
wchar_t* filepart = PathFindFileName(filename.c_str());
PathRemoveExtension(filepart); 

http://msdn.microsoft.com/en-us/library/windows/desktop/bb773589(v=vs.85).aspx

The drawback is that you have to link to shlwapi.lib, but I'm not really sure why that's a drawback.

Ok, Here's what I found out.

What I didn't understand is that all fragments that are attached to an activity when a config change happens (phone rotates) are recreated and added back to the activity. (which makes sense)

What was happening in the TabListener constructor was the tab was detached if it was found and attached to the activity. See below:

mFragment = mActivity.getFragmentManager().findFragmentByTag(mTag);
    if (mFragment != null && !mFragment.isDetached()) {
        Log.d(TAG, "constructor: detaching fragment " + mTag);
        FragmentTransaction ft = mActivity.getFragmentManager().beginTransaction();
        ft.detach(mFragment);
        ft.commit();
    }

Later in the activity onCreate the previously selected tab was selected from the saved instance state. See below:

if (savedInstanceState != null) {
    bar.setSelectedNavigationItem(savedInstanceState.getInt("tab", 0));
    Log.d(TAG, "FragmentTabs.onCreate tab: " + savedInstanceState.getInt("tab"));
    Log.d(TAG, "FragmentTabs.onCreate number: " + savedInstanceState.getInt("number"));
}

When the tab was selected it would be reattached in the onTabSelected callback.

public void onTabSelected(Tab tab, FragmentTransaction ft) {
    if (mFragment == null) {
        mFragment = Fragment.instantiate(mActivity, mClass.getName(), mArgs);
        Log.d(TAG, "onTabSelected adding fragment " + mTag);
        ft.add(android.R.id.content, mFragment, mTag);
    } else {
        Log.d(TAG, "onTabSelected attaching fragment " + mTag);
        ft.attach(mFragment);
    }
}

The fragment being attached is the second call to the onCreateView and onActivityCreated methods. (The first being when the system is recreating the acitivity and all attached fragments) The first time the onSavedInstanceState Bundle would have saved data but not the second time.

The solution is to not detach the fragment in the TabListener constructor, just leave it attached. (You still need to find it in the FragmentManager by it's tag) Also, in the onTabSelected method I check to see if the fragment is detached before I attach it. Something like this:

public void onTabSelected(Tab tab, FragmentTransaction ft) {
            if (mFragment == null) {
                mFragment = Fragment.instantiate(mActivity, mClass.getName(), mArgs);
                Log.d(TAG, "onTabSelected adding fragment " + mTag);
                ft.add(android.R.id.content, mFragment, mTag);
            } else {

                if(mFragment.isDetached()) {
                    Log.d(TAG, "onTabSelected attaching fragment " + mTag);
                    ft.attach(mFragment);
                } else {
                    Log.d(TAG, "onTabSelected fragment already attached " + mTag);
                }
            }
        }

In my case, There were new code branch and old code branch was deployed locally in IIS. So it was pointing to old branch code that was not available. So i had deployed my code to IIS with new branch and it is working now.

you can use pattern matcher as well, which will replace all in one shot.

Pattern keyPattern = Pattern.compile(key); Matcher matcher = keyPattern.matcher(str); String nerSrting = matcher.replaceAll(value);

Also works fine within a class:

def update_property(self, property, value):
   setattr(self, property, value)

Apart from the accepted answer, I'm suggesting another alternative. Use QueryDSL, create a predicate and use the exists() method that accepts a predicate and returns Boolean.

One advantage with QueryDSL is you can use the predicate for complicated where clauses.

What about x *= -1; ? Do you really want a library function for this?

In addition to the already established answers, with ES6 arrow functions Promises turn from a modestly shining small blue dwarf straight into a red giant. That is about to collapse into a supernova:

api().then(result => api2()).then(result2 => api3()).then(result3 => console.log(result3))

As oligofren pointed out, without arguments between api calls you don't need the anonymous wrapper functions at all:

api().then(api2).then(api3).then(r3 => console.log(r3))

And finally, if you want to reach a supermassive black hole level, Promises can be awaited:

async function callApis() {
    let api1Result = await api();
    let api2Result = await api2(api1Result);
    let api3Result = await api3(api2Result);

    return api3Result;
}

primary keys are automatically indexed

you can create additional indices using the pk depending on your usage

• index zip_code, id may be helpful if you often select by zip_code and id

This method worked for me:

 public static String daysBetween(String day1, String day2) {
    String daysBetween = "";
    SimpleDateFormat myFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    try {
        Date date1 = myFormat.parse(day1);
        Date date2 = myFormat.parse(day2);
        long diff = date2.getTime() - date1.getTime();
        daysBetween = ""+(TimeUnit.DAYS.convert(diff, TimeUnit.MILLISECONDS));
    } catch (ParseException e) {
        e.printStackTrace();
    }
    return daysBetween;
}

Mysql by default has root user's authentication plugin as auth_socket, which requires the system user name and db user name to be the same.

Specifically, log in as root or sudo -i and just type mysql and you will be logged in as mysql root, you can then create other operating users.

If you do not have a root on host, I guess you should not be allowed to login to mysql as root?

they're not really ordered, but you can do:

var first;
for (var i in obj) {
    if (obj.hasOwnProperty(i) && typeof(i) !== 'function') {
        first = obj[i];
        break;
    }
}

the .hasOwnProperty() is important to ignore prototyped objects.

Use the following for multiple .cpp files

g++ *.cpp
./a.out

If you find search and replace faster to use, you could use a regex replace like this:

Find (regex): (^|\G) {2} (Instead of " {2}" <space>{2} you can just write two spaces. Used it here for clarity.)

Replace with 4 spaces, or whatever you want, like \t.

First try to open the file with a decompiler such as ILSpy, your dll might be corrupt. I had this error on an online web site, when I downloaded the dll and tried to open it, it was corrupt, probably some error occurred while uploading it via ftp.

I have a similar solution to the above and it works for opening, saving, file selecting. I paste it into its own module and use in all the Access DB's I create. As the code states it requires Microsoft Office 14.0 Object Library. Just another option I suppose:

Public Function Select_File(InitPath, ActionType, FileType)
    ' Requires reference to Microsoft Office 14.0 Object Library.

    Dim fDialog As Office.FileDialog
    Dim varFile As Variant


    If ActionType = "FilePicker" Then
        Set fDialog = Application.FileDialog(msoFileDialogFilePicker)
        ' Set up the File Dialog.
    End If
    If ActionType = "SaveAs" Then
        Set fDialog = Application.FileDialog(msoFileDialogSaveAs)
    End If
    If ActionType = "Open" Then
        Set fDialog = Application.FileDialog(msoFileDialogOpen)
    End If
    With fDialog

The one liner : bind() to own address, connect() to remote address.

Quoting from the man page of bind()

bind() assigns the address specified by addr to the socket referred to by the file descriptor sockfd. addrlen specifies the size, in bytes, of the address structure pointed to by addr. Traditionally, this operation is called "assigning a name to a socket".

and, from the same for connect()

The connect() system call connects the socket referred to by the file descriptor sockfd to the address specified by addr.

To clarify,

• bind() associates the socket with its local address [that's why server side binds, so that clients can use that address to connect to server.]
• connect() is used to connect to a remote [server] address, that's why is client side, connect [read as: connect to server] is used.

If you have to ask an user to give input and then you have to count how many numbers are there then you can follow this:

count_number = input('Please enter a number\t')

print(len(count_number))

Note: Never take an int as user input.

Setting Up the database

public class DatabaseHelper extends SQLiteOpenHelper {
    // Database Version
    private static final int DATABASE_VERSION = 1;

    // Database Name
    private static final String DATABASE_NAME = "database_name";

    // Table Names
    private static final String DB_TABLE = "table_image";

    // column names
    private static final String KEY_NAME = "image_name";
    private static final String KEY_IMAGE = "image_data";

    // Table create statement
    private static final String CREATE_TABLE_IMAGE = "CREATE TABLE " + DB_TABLE + "("+ 
                       KEY_NAME + " TEXT," + 
                       KEY_IMAGE + " BLOB);";

    public DatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {

        // creating table
        db.execSQL(CREATE_TABLE_IMAGE);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // on upgrade drop older tables
        db.execSQL("DROP TABLE IF EXISTS " + DB_TABLE);

        // create new table
        onCreate(db);
    }
}

Insert in the Database:

public void addEntry( String name, byte[] image) throws SQLiteException{
    SQLiteDatabase database = this.getWritableDatabase();
    ContentValues cv = new  ContentValues();
    cv.put(KEY_NAME,    name);
    cv.put(KEY_IMAGE,   image);
    database.insert( DB_TABLE, null, cv );
}

Retrieving data:

 byte[] image = cursor.getBlob(1);

Note:

1. Before inserting into database, you need to convert your Bitmap image into byte array first then apply it using database query.
2. When retrieving from database, you certainly have a byte array of image, what you need to do is to convert byte array back to original image. So, you have to make use of BitmapFactory to decode.

Below is an Utility class which I hope could help you:

public class DbBitmapUtility {

    // convert from bitmap to byte array
    public static byte[] getBytes(Bitmap bitmap) {
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(CompressFormat.PNG, 0, stream);
        return stream.toByteArray();
    }

    // convert from byte array to bitmap
    public static Bitmap getImage(byte[] image) {
        return BitmapFactory.decodeByteArray(image, 0, image.length);
    }
}

If you are not familiar how to insert and retrieve into a database, go through this tutorial.

Mid(strYourString, 4) (i.e. without the optional length argument) will return the substring starting from the 4th character and going to the end of the string.

CLOCK_REALTIME is affected by NTP, and can move forwards and backwards. CLOCK_MONOTONIC is not, and advances at one tick per tick.

Since your question is more generic so try to implement it with XML Parsers available in Java .If you need it in specific to parsers, update your code here what you have tried yet

<?xml version="1.0" encoding="UTF-8"?>
<ep>
    <source type="xml">TEST</source>
    <source type="text"></source>
</ep>

DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse("uri to xmlfile");
XPathFactory xPathfactory = XPathFactory.newInstance();
XPath xpath = xPathfactory.newXPath();
XPathExpression expr = xpath.compile("//ep/source[@type]");
NodeList nl = (NodeList) expr.evaluate(doc, XPathConstants.NODESET);

for (int i = 0; i < nl.getLength(); i++)
{
    Node currentItem = nl.item(i);
    String key = currentItem.getAttributes().getNamedItem("type").getNodeValue();
    System.out.println(key);
}

Use the group collection of the Match object, indexing it with the capturing group name, e.g.

foreach (Match m in mc){
    MessageBox.Show(m.Groups["link"].Value);
}

PostgreSQL also supports full POSIX regular expressions:

select * from table where value ~* 'foo|bar|baz';

The ~* is for a case insensitive match, ~ is case sensitive.

Another option is to use ANY:

select * from table where value  like any (array['%foo%', '%bar%', '%baz%']);
select * from table where value ilike any (array['%foo%', '%bar%', '%baz%']);

You can use ANY with any operator that yields a boolean. I suspect that the regex options would be quicker but ANY is a useful tool to have in your toolbox.

I am able to fix this issue by marking "Copy Local=True" on all referenced DLL files in the project, rebuilding and deploying on a testing server.

There are two options. The first (and better) one is using the Fetch as Google option in Webmaster Tools that Mike Flynn commented about. Here are detailed instructions:

1. Go to: https://www.google.com/webmasters/tools/ and log in
2. If you haven't already, add and verify the site with the "Add a Site" button
3. Click on the site name for the one you want to manage
4. Click Crawl -> Fetch as Google
5. Optional: if you want to do a specific page only, type in the URL
6. Click Fetch
7. Click Submit to Index
8. Select either "URL" or "URL and its direct links"
9. Click OK and you're done.

With the option above, as long as every page can be reached from some link on the initial page or a page that it links to, Google should recrawl the whole thing. If you want to explicitly tell it a list of pages to crawl on the domain, you can follow the directions to submit a sitemap.

Your second (and generally slower) option is, as seanbreeden pointed out, submitting here: http://www.google.com/addurl/

Update 2019:

1. Login to - Google Search Console
2. Add a site and verify it with the available methods.
3. After verification from the console, click on URL Inspection.
4. In the Search bar on top, enter your website URL or custom URLs for inspection and enter.
5. After Inspection, it'll show an option to Request Indexing
6. Click on it and GoogleBot will add your website in a Queue for crawling.

You need to close the XML with </web-app>, not with <web-app>.

The Win32_Process class provides access to both 32-bit and 64-bit processes when the script is run from a 64-bit command shell.

If this is not an option for you, you can try using the taskkill command:

Dim oShell : Set oShell = CreateObject("WScript.Shell")

' Launch notepad '
oShell.Run "notepad"
WScript.Sleep 3000

' Kill notepad '
oShell.Run "taskkill /im notepad.exe", , True

I generally use array split because it's easier simple syntax and scales better with more than 2 partitions.

import numpy as np
partitions = 2
dfs = np.array_split(df, partitions)

np.split(df, [100,200,300], axis=0] wants explicit index numbers which may or may not be desirable.

Looks like things have changed and the previous solution doesn't work anymore.

However, here is the working command to launch CNN.com on Microsoft Edge:

microsoft-edge:http://www.cnn.com

I'm use

echo date("Y-m-d H:i:s.").gettimeofday()["usec"];

output: 2017-09-05 17:04:57.555036

In fact you can effectively add in your css .ui-datepicker{ z-index: 9999 !important;} but you can modify jquery-ui.css or jquery-ui.min.css and add at the end of the ui-datepicker class z-index: 9999 !important;. both things work for me (You only need one ;-))

mock.patch is a very very different critter than mock.Mock. patch replaces the class with a mock object and lets you work with the mock instance. Take a look at this snippet:

>>> class MyClass(object):
...   def __init__(self):
...     print 'Created MyClass@{0}'.format(id(self))
... 
>>> def create_instance():
...   return MyClass()
... 
>>> x = create_instance()
Created MyClass@4299548304
>>> 
>>> @mock.patch('__main__.MyClass')
... def create_instance2(MyClass):
...   MyClass.return_value = 'foo'
...   return create_instance()
... 
>>> i = create_instance2()
>>> i
'foo'
>>> def create_instance():
...   print MyClass
...   return MyClass()
...
>>> create_instance2()
<mock.Mock object at 0x100505d90>
'foo'
>>> create_instance()
<class '__main__.MyClass'>
Created MyClass@4300234128
<__main__.MyClass object at 0x100505d90>

patch replaces MyClass in a way that allows you to control the usage of the class in functions that you call. Once you patch a class, references to the class are completely replaced by the mock instance.

mock.patch is usually used when you are testing something that creates a new instance of a class inside of the test. mock.Mock instances are clearer and are preferred. If your self.sut.something method created an instance of MyClass instead of receiving an instance as a parameter, then mock.patch would be appropriate here.

You need to reload the entity after saving changes. Because it has been altered by a database trigger which cannot be tracked by EF. SO we need to reload the entity again from the DB,

db.Entry(MyNewObject).GetDatabaseValues();

Then

int id = myNewObject.Id;

Look at @jayantha answer in below question:

How can I get Id of the inserted entity in Entity framework when using defaultValue?

Looking @christian answer in below question may help too:

Entity Framework Refresh context?

String path = "C:\\Documents and Settings\\someDir";
path = path.replaceAll("\\\\", "/");

In Windows you should use four backslash but not two.

:-) If not typo, why are you using ./commonRT instead of ./commonKT ??

Update for RxJS 6 (April 2018)

It is now perfectly fine to import directly from rxjs. (As can be seen in Angular 6+). Importing from rxjs/operators is also fine and it is actually no longer possible to import operators globally (one of major reasons for refactoring rxjs 6 and the new approach using pipe). Thanks to this treeshaking can now be used as well.

Sample code from rxjs repo:

import { Observable, Subject, ReplaySubject, from, of, range } from 'rxjs';
import { map, filter, switchMap } from 'rxjs/operators';

range(1, 200)
  .pipe(filter(x => x % 2 === 1), map(x => x + x))
  .subscribe(x => console.log(x));

Backwards compatibility for rxjs < 6?

rxjs team released a compatibility package on npm that is pretty much install & play. With this all your rxjs 5.x code should run without any issues. This is especially useful now when most of the dependencies (i.e. modules for Angular) are not yet updated.

With ObsoleteAttribute you can to show the deprecated method. Obsolete attribute has three constructor:

1. [Obsolete]: is a no parameter constructor and is a default using this attribute.
2. [Obsolete(string message)]: in this format you can get message of why this method is deprecated.
3. [Obsolete(string message, bool error)]: in this format message is very explicit but error means, in compilation time, compiler must be showing error and cause to fail compiling or not.

How about using os.kill? See the docs here: http://docs.python.org/library/os.html#os.kill

Instead, you simply JOIN to both tables, and in your SELECT clause, return data from the one that matches:

I suggest you to go through this link Conditional Joins in SQL Server and T-SQL Case Statement in a JOIN ON Clause

e.g.

    SELECT  *
FROM    sys.indexes i
        JOIN sys.partitions p
            ON i.index_id = p.index_id 
        JOIN sys.allocation_units a
            ON a.container_id =
            CASE
               WHEN a.type IN (1, 3)
                   THEN  p.hobt_id 
               WHEN a.type IN (2)
                   THEN p.partition_id
               END 

Edit: As per comments.

You can not specify the join condition as you are doing.. Check the query above that have no error. I have take out the common column up and the right column value will be evaluated on condition.

It's usually \t in command-line interfaces, which will convert the char \t into the whitespace tab character.

For example, hello\talex -> hello--->alex.

MySQL / SQL Server / Oracle / MS Access:

ALTER TABLE Orders
ADD FOREIGN KEY (P_Id)
REFERENCES Persons(P_Id)

To allow naming of a FOREIGN KEY constraint, and for defining a FOREIGN KEY constraint on multiple columns, use the following SQL syntax:

MySQL / SQL Server / Oracle / MS Access:

ALTER TABLE Orders
ADD CONSTRAINT fk_PerOrders
FOREIGN KEY (P_Id)
REFERENCES Persons(P_Id)

The combination of map and lambda functions in Python is a good solution for this kind of problem:

a = [2,2,2]
b = [1,1,1]
map(lambda x,y: x-y, a,b)

zip function is another good choice, as demonstrated by @UncleZeiv

I realize this is an old thread, but for those taking @JasonMArcher's accepted answer above as fact, I'm surprised it has not been corrected many of us have known for years it is actually the PIPELINE adding the delay and NOTHING to do with whether it is Out-Null or not. In fact, if you run the tests below you will quickly see that the same "faster" casting to [void] and $void= that for years we all used thinking it was faster, are actually JUST AS SLOW and in fact VERY SLOW when you add ANY pipelining whatsoever. In other words, as soon as you pipe to anything, the whole rule of not using out-null goes into the trash.

Proof, the last 3 tests in the list below. The horrible Out-null was 32339.3792 milliseconds, but wait - how much faster was casting to [void]? 34121.9251 ms?!? WTF? These are REAL #s on my system, casting to VOID was actually SLOWER. How about =$null? 34217.685ms.....still friggin SLOWER! So, as the last three simple tests show, the Out-Null is actually FASTER in many cases when the pipeline is already in use.

So, why is this? Simple. It is and always was 100% a hallucination that piping to Out-Null was slower. It is however that PIPING TO ANYTHING is slower, and didn't we kind of already know that through basic logic? We just may not have know HOW MUCH slower, but these tests sure tell a story about the cost of using the pipeline if you can avoid it. And, we were not really 100% wrong because there is a very SMALL number of true scenarios where out-null is evil. When? When adding Out-Null is adding the ONLY pipeline activity. In other words....the reason a simple command like $(1..1000) | Out-Null as shown above showed true.

If you simply add an additional pipe to Out-String to every test above, the #s change radically (or just paste the ones below) and as you can see for yourself, the Out-Null actually becomes FASTER in many cases:

$GetProcess = Get-Process

Take a look at PHP COM documents (The comments are helpful) http://us3.php.net/com

For embedding HTML text in your textview you can use Html.fromHTML() syntax. More information you will get from http://developer.android.com/reference/android/text/Html.html#fromHtml%28java.lang.String%29

Swift 3:

As suggested above I'm using FLAnimatedImage with an FLAnimatedImageView. And I'm loading the gif as a data set from xcassets. This allows me to provide different gifs for iphone and ipad for appearance and app slicing purposes. This is far more performant than anything else I've tried. It's also easy to pause using .stopAnimating().

if let asset = NSDataAsset(name: "animation") {
    let gifData = asset.data
    let gif = FLAnimatedImage(animatedGIFData: gifData)
    imageView.animatedImage = gif
  }

For me, I managed to make it work that way. I deployed the automatic click in 5000 milliseconds and then closed the loop after 1000 milliseconds. Then there was only 1 automatic click.

<script> var myVar = setInterval(function ({document.getElementById("test").click();}, 500)); setInterval(function () {clearInterval(myVar)}, 1000));</script>

If you're trying to load a DataTable, then leverage the SqlDataAdapter instead:

DataTable dt = new DataTable();

using (SqlConnection c = new SqlConnection(cString))
using (SqlDataAdapter sda = new SqlDataAdapter(sql, c))
{
    sda.SelectCommand.CommandType = CommandType.StoredProcedure;
    sda.SelectCommand.Parameters.AddWithValue("@parm1", val1);
    ...

    sda.Fill(dt);
}

You don't even need to define the columns. Just create the DataTable and Fill it.

Here, cString is your connection string and sql is the stored procedure command.

How about \A[a-z]*Id\z? [This makes characters before Id optional. Use \A[a-z]+Id\z if there needs to be one or more characters preceding Id.]

You can use the standard MaterialCard included in the official Material Components library.

Use in your layout:

<com.google.android.material.card.MaterialCardView
        style="@style/MyCardView"
        ...>

In your style use the shapeAppearanceOverlay attribute to customize the shape (the default corner radius is 4dp)

  <style name="MyCardView" parent="@style/Widget.MaterialComponents.CardView">
    <item name="shapeAppearanceOverlay">@style/ShapeAppearanceOverlay.MaterialCardView.Cut</item>
  </style>


  <style name="ShapeAppearanceOverlay.MaterialCardView.Cut" parent="">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSizeTopRight">8dp</item>
    <item name="cornerSizeTopLeft">8dp</item>
    <item name="cornerSizeBottomRight">0dp</item>
    <item name="cornerSizeBottomLeft">0dp</item>
  </style>

You can also use:

<com.google.android.material.card.MaterialCardView
     app:shapeAppearanceOverlay="@style/ShapeAppearanceOverlay.MaterialCardView.Cut"
     ...>

It is the result:

Hi our sturucture is like Application, system, user_guide

create a folder name assets just near all the folders and then inside this assets folder create css and javascript and images folder put all your css js insiide the folders

now go to header.php and call the css just like this.

<link rel="stylesheet" href="<?php echo base_url();?>assets/css/touchTouch.css">
  <link rel="stylesheet" href="<?php echo base_url();?>assets/css/style.css">
  <link rel="stylesheet" href="<?php echo base_url();?>assets/css/camera.css"> 

If those elements have a common class name, one may also use this:

$('#your_div .your_classname').serialize()

This way you can avoid selection of buttons, which will be selected using the jQuery selector :input. Though this can also be avoided by using $('#your_div :input:not(:button)').serialize();

new XElement("Foo",
       from s in nameValuePairList
       select
             new XElement("Bar",
                  new XAttribute("SomeAttr", "SomeAttrValue"),
                          new XElement("Name", s.Name),
                          new XElement("Value", s.Value)
                         )
            );

Your student.h file only forward declares a struct named "Student", it does not define one. This is sufficient if you only refer to it through reference or pointer. However, as soon as you try to use it (including creating one) you will need the full definition of the structure.

In short, move your struct Student { ... }; into the .h file and use the .cpp file for implementation of member functions (which it has none so you don't need a .cpp file).

I just met the same problem with mysql 5.7 on OSX:

rm -rf {datadir}
mysqld --initialize --datadir {datadir}
mysqld --datadir {datadir}

The Android SDK path is usually C:\Users\<username>\AppData\Local\Android\sdk.

You can also use plt.setp as follows:

import matplotlib.pyplot as plt
import seaborn as sns

plot=sns.barplot(data=df,  x=" ", y=" ")
plt.setp(plot.get_xticklabels(), rotation=90)

to rotate the labels 90 degrees.

I found it pretty easy like this

    using System;
    using System.Data;
    using System.IO;
    using Excel;

    public DataTable ExcelToDataTableUsingExcelDataReader(string storePath)
    {
        FileStream stream = File.Open(storePath, FileMode.Open, FileAccess.Read);

        string fileExtension = Path.GetExtension(storePath);
        IExcelDataReader excelReader = null;
        if (fileExtension == ".xls")
        {
            excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
        }
        else if (fileExtension == ".xlsx")
        {
            excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
        }

        excelReader.IsFirstRowAsColumnNames = true;
        DataSet result = excelReader.AsDataSet();
        var test = result.Tables[0];
        return result.Tables[0];
    }

Note: you need to install SharpZipLib package for this

Install-Package SharpZipLib

neat and clean! ;)

You Can Select the Id using a Function

<option *ngFor="#c of countries" (change)="onchange(c.id)">{{c.name}}</option>

I know this is SUPER old... but just for fun I decided to give this a try:

@Echo OFF
setlocal
set testpath=%path: =#%
FOR /F "tokens=* delims=;" %%P in ("%testpath%") do call :loop %%P
:loop
if '%1'=='' goto endloop
set testpath=%1
set testpath=%testpath:#= %
echo %testpath%
SHIFT
goto :loop
:endloop
pause
endlocal
exit

This doesn't require a count and will go until it finishes. I had the same problem with spaces but it made it through the entire variable. The key to this is the loop labels and the SHIFT function.

There is a simple way:

Android:

   String macAddress = 
android.provider.Settings.Secure.getString(this.getApplicationContext().getContentResolver(), "android_id");

Xamarin:

    Settings.Secure.GetString(this.ContentResolver, "android_id");

You are checking whether the string contains all illegal characters. Change the ||s to &&s.
