This happens because $cOTLdata is not null but the index 'char_data' does not exist. Previous versions of PHP may have been less strict on such mistakes and silently swallowed the error / notice while 7.4 does not do this anymore.

To check whether the index exists or not you can use isset():

isset($cOTLdata['char_data'])

Which means the line should look something like this:

$len = isset($cOTLdata['char_data']) ? count($cOTLdata['char_data']) : 0;

Note I switched the then and else cases of the ternary operator since === null is essentially what isset already does (but in the positive case).

I have resolved this issue after selecting the "Target Compatibility" to 1.8 Java version. File -> Project Structure -> Modules.

If you are getting this error only when you are generating signed Apk . Then the problem might be in one or more of the imported media file format. I have used an image directly from net to studio and was not able to generate sign apk, then found the error .

from Gradle >assembleRelease then got the error in console. see the error log in console image.

My scenario:

old Kotlin dataclass:

data class AddHotelParams(val destination: Place?, val checkInDate: LocalDate,
                      val checkOutDate: LocalDate?): JsonObject

new Kotlin dataclass:

data class AddHotelParams(val destination: Place?, val checkInDate: LocalDate,
                      val checkOutDate: LocalDate?, val roundTrip: Boolean): JsonObject

The problem was that I forgot to change the object initialization in some parts of the code. I got a generic "compileInternalDebugKotlin" error instead of being told where I needed to change the initialization.

changing initialization to all parts of the code resolved the error.

first you remove this thing in your project .. its is in build.gradle(module:app) then build your app now you project show the actual error and you find what is your actual problem is .. and after you find actual problem again paste it where its is belong to

allprojects { gradle.projectsEvaluated {

    tasks.withType(JavaCompile)

{ options.encoding = 'UTF-8'

        options.compilerArgs

<< "-Xlint:unchecked" << "-Xlint:deprecation"}]}}

Sol 1: In build.gradle:

defaultConfig {
    multiDexEnabled true
}

Clean your project and rebuild.

Sol 2: in local.properties add,

org.gradle.jvmargs=-XX\:MaxHeapSize\=512m -Xmx512m

Sol 3

compile 'com.android.support:multidex:1.0.1'

Else add all 3 in your application.

Practical answer -- you can always delete a terminating pod by running:

kubectl delete pod NAME --grace-period=0

Historical answer -- There was an issue in version 1.1 where sometimes pods get stranded in the Terminating state if their nodes are uncleanly removed from the cluster.

I realize this question was asked and answered a long time ago, but the answers don't give what I feel is the simplest solution. It's almost always a good idea to avoid loops whenever possible, and matplotlib's plot is capable of plotting multiple lines with one command. If x and y are arrays, then plot draws one line for every column.

In your case, you can do the following:

x=np.array([-1 ,0.5 ,1,-0.5])
xx = np.vstack([x[[0,2]],x[[1,3]]])
y=np.array([ 0.5,  1, -0.5, -1])
yy = np.vstack([y[[0,2]],y[[1,3]]])
plt.plot(xx,yy, '-o')

Have a long list of x's and y's, and want to connect adjacent pairs?

xx = np.vstack([x[0::2],x[1::2]])
yy = np.vstack([y[0::2],y[1::2]])

Want a specified (different) color for the dots and the lines?

plt.plot(xx,yy, '-ok', mfc='C1', mec='C1')

In my case, This problem was caused by a mismatch in my Target framework setting under each project. When I created a new project, VS 2015 defaulted to 4.5.2, however all my nuget packages were built for 4.6.

For some reason, VS 2015 was not showing me these errors. I didn't see them until I created a new empty project and tried to add my nuget project there. This behavior may have been aggravated because I had renamed the project a few times during the initial setup.

I solved the problem by

• changing the Target Framework on my projects to 4.6
• closed VS 2015
• deleted "packages", "obj" and "bin" folders
• re-open the solution and try to add the nuget package again.

In my case, the problem occurred when writing in Kotlin and using IDEA 2020.3. Despite proper entries in build.gradle.kts. It turned out that the problem was when generating test functions by IDEA IDE (Alt + Insert). It generates the following code:

@Test
   internal fun name () {
     TODO ("Not yet implemented")
   }

And the problem will be fixed after removing the "internal" modifier:

@Test
   fun name () {
     TODO ("Not yet implemented")
   }

Today I also met this problem. Here is how I solved it:

1. I built the app, then I saw the errors in the message window. They said the picture (with the full path) was malformed.
2. Then I found the malformed png which had the name xxx.9.png.
3. I renamed it to xxx9.png and rebuilt. There were no errors, and the java files with the red wave under the name are gone too.

window.scrollTo(0,1);

this will help you but this javascript is may not work in all browsers

Just found an article from Anand Mani Sankar wich shows a simple way of using nginx upstream proxy with docker composer.

Basically one must configure the instance linking and ports at the docker-compose file and update upstream at nginx.conf accordingly.

Above answers are in python2. So for python 3 users I am giving this answer. You can use the bellow code:

import pandas as pd
fields = ['star_name', 'ra']

df = pd.read_csv('data.csv', skipinitialspace=True, usecols=fields)
# See the keys
print(df.keys())
# See content in 'star_name'
print(df.star_name)

Maybe you should reset frame of the button, I had some problem too, and nslog the view of keyboard like this:

ios8:

"<UIInputSetContainerView: 0x7fef0364b0d0; frame = (0 0; 320 568); autoresize = W+H; layer = <CALayer: 0x7fef0364b1e0>>"

before8:

"<UIPeripheralHostView: 0x11393c860; frame = (0 352; 320 216); autoresizesSubviews = NO; layer = <CALayer: 0x11393ca10>>"

Xcode: 6.4 iOS:8 I got this error as well, but for a very different reason.

//UIKeyboardTypeNumberPad needs a "Done" button    
UIBarButtonItem *doneBarButton = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemDone
                                                                              target:self
                                                                              action:@selector(doneBarButtonTapped:)];

enhancedNumpadToolbar = [[UIToolbar alloc]init]; // previously declared
[self.enhancedNumpadToolbar setItems:@[doneBarButton]];
self.myNumberTextField.inputAccessoryView = self.enhancedNumpadToolbar; //txf previously declared

I got the same error (save mine was "type 4" rather than "type 8"), until I discovered that I was missing this line:

[self.enhancedNumpadToolbar sizeToFit];

I added it, and the sun started shining, the birds resumed chirping, and all was well with the world.

PS You would also get such an error for other mischief, such as forgetting to alloc/init.

The python error says that wordInput is not an iterable -> it is of NoneType.

If you print wordInput before the offending line, you will see that wordInput is None.

Since wordInput is None, that means that the argument passed to the function is also None. In this case word. You assign the result of pickEasy to word.

The problem is that your pickEasy function does not return anything. In Python, a method that didn't return anything returns a NoneType.

I think you wanted to return a word, so this will suffice:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")
    return word

@Balamanigandan your Original Post :- PHP Notice: Trying to get property of non-object error

Your are trying to access the Null Object. From AngularJS your are not passing any Objects instead you are passing the $_GET element. Try by using $_GET['uid'] instead of $objData->token

i can handle it like that ;

svg.selectAll("rect")
    .data(zones)
    .enter()
    .append("rect")
    .attr("id", function (d) { return "zone" + d.zone; })
    .attr("class", "zone")
    .attr("x", function (d, i) {
        if (parseInt(i / (wcount)) % 2 == 0) {
            this.xcor = (i % wcount) * zoneW;
        }
        else {
            this.xcor = (zoneW * (wcount - 1)) - ((i % wcount) * zoneW);
        }

        return this.xcor;
    })

and anymore you can find x coordinate

svg.select("#zone1").on("click",function(){alert(this.xcor});

Found the solution to this problem:

gradle assemble -info gave me the hint that the Manifests have different SDK Versions and cannot be merged.

I needed to edit my Manifests and build.gradle file and everything worked again.

To be clear you need to edit the uses-sdk in the AndroidManifest.xml

<uses-sdk android:minSdkVersion="14" android:targetSdkVersion="16" />

and the android section, particularly minSdkVersion and targetSdkVersion in the build.gradle file

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 16
    }
}

I think all you need to do for your function is just add PtrSafe: i.e. the first line of your first function should look like this:

Private Declare PtrSafe Function swe_azalt Lib "swedll32.dll" ......

You can use pad for this case:

ax.set_title("whatever", pad=20)

Here is an actual implementation of what you described. I rewrote your code a bit using the latest best practices to actualize is. If you resize your browser windows under 1000px, the image's left and right side will be cropped using negative margins and it will be 300px narrower.

<style>
   .container {
      position: relative;
      width: 100%;
   }

   .bg {
      position:relative;
      z-index: 1;
      height: 100%;
      min-width: 1000px;
      max-width: 1500px;
      margin: 0 auto;
   }

   .nebula {
      width: 100%;
   }

   @media screen and (max-width: 1000px) {
      .nebula {
         width: 100%;
         overflow: hidden;
         margin: 0 -150px 0 -150px;
      }
   }
</style>

<div class="container">
   <div class="bg">
      <img src="http://i.stack.imgur.com/tFshX.jpg" class="nebula">
   </div>

The primary advantage is type safety. With a set of constants, any value of the same intrinsic type could be used, introducing errors. With an enum only the applicable values can be used.

For example

public static final int SIZE_SMALL  = 1;
public static final int SIZE_MEDIUM = 2;
public static final int SIZE_LARGE  = 3;

public void setSize(int newSize) { ... }

obj.setSize(15); // Compiles but likely to fail later

vs

public enum Size { SMALL, MEDIUM, LARGE };

public void setSize(Size s) { ... }

obj.setSize( ? ); // Can't even express the above example with an enum

geonames is nice. an export tool based on geonames:

there's also the excellent pycountry module:

In this example code node[k] is just the kth node. You are generating an array N points and node[k] is the kth (from 0 to N-1). If that is all that is confusing you, hopefully you can use that now.

(in other words, k is an array of size N that is defined before the code fragment starts, and which contains a list of the points).

Alternatively, building on the other answer here (and using Python):

> cat ll.py
from math import asin
nx = 4; ny = 5
for x in range(nx):
    lon = 360 * ((x+0.5) / nx)
    for y in range(ny):                                                         
        midpt = (y+0.5) / ny                                                    
        lat = 180 * asin(2*((y+0.5)/ny-0.5))                                    
        print lon,lat

If you plot that, you'll see that the vertical spacing is larger near the poles so that each point is situated in about the same total area of space (near the poles there's less space "horizontally", so it gives more "vertically").

This isn't the same as all points having about the same distance to their neighbours (which is what I think your links are talking about), but it may be sufficient for what you want and improves on simply making a uniform lat/lon grid.

I'm pretty sure it's an Adobe standard, bearing in mind the whole PDF standard is theirs to begin with; despite being open now.

My guess would be no for all PDF viewers supporting it, as some definitely will not have a JS engine. I doubt you can rely on full support outside the most recent versions of Acrobat (Reader). So I guess it depends on how you imagine it being used, if mainly via a browser display, then the majority of the market is catered for by Acrobat (Reader) and Chrome's built-in viewer - dare say there is documentation on whether Chrome's PDF viewer supports JS fully.

There are already a lot of good answers here. For fun, I implemented this solution below, based on the other answers and my own ideas.

<input class="adjust">

The input element is adjusted pixel accurate and an additional offset can be defined.

function adjust(elements, offset, min, max) {

    // Initialize parameters
    offset = offset || 0;
    min    = min    || 0;
    max    = max    || Infinity;
    elements.each(function() {
        var element = $(this);

        // Add element to measure pixel length of text
        var id = btoa(Math.floor(Math.random() * Math.pow(2, 64)));
        var tag = $('<span id="' + id + '">' + element.val() + '</span>').css({
            'display': 'none',
            'font-family': element.css('font-family'),
            'font-size': element.css('font-size'),
        }).appendTo('body');

        // Adjust element width on keydown
        function update() {

            // Give browser time to add current letter
            setTimeout(function() {

                // Prevent whitespace from being collapsed
                tag.html(element.val().replace(/ /g, '&nbsp'));

                // Clamp length and prevent text from scrolling
                var size = Math.max(min, Math.min(max, tag.width() + offset));
                if (size < max)
                    element.scrollLeft(0);

                // Apply width to element
                element.width(size);
            }, 0);
        };
        update();
        element.keydown(update);
    });
}

// Apply to our element
adjust($('.adjust'), 10, 100, 500);

The adjustment gets smoothed with a CSS transition.

.adjust {
    transition: width .15s;
}

Here is the fiddle. I hope this can help others looking for a clean solution.

C# 6 adds a new feature just for this: extension Add methods. This has always been possible for VB.net but is now available in C#.

Now you don't have to add Add() methods to your classes directly, you can implement them as extension methods. When extending any enumerable type with an Add() method, you'll be able to use it in collection initializer expressions. So you don't have to derive from lists explicitly anymore (as mentioned in another answer), you can simply extend it.

public static class TupleListExtensions
{
    public static void Add<T1, T2>(this IList<Tuple<T1, T2>> list,
            T1 item1, T2 item2)
    {
        list.Add(Tuple.Create(item1, item2));
    }

    public static void Add<T1, T2, T3>(this IList<Tuple<T1, T2, T3>> list,
            T1 item1, T2 item2, T3 item3)
    {
        list.Add(Tuple.Create(item1, item2, item3));
    }

    // and so on...
}

This will allow you to do this on any class that implements IList<>:

var numbers = new List<Tuple<int, string>>
{
    { 1, "one" },
    { 2, "two" },
    { 3, "three" },
    { 4, "four" },
    { 5, "five" },
};
var points = new ObservableCollection<Tuple<double, double, double>>
{
    { 0, 0, 0 },
    { 1, 2, 3 },
    { -4, -2, 42 },
};

Of course you're not restricted to extending collections of tuples, it can be for collections of any specific type you want the special syntax for.

public static class BigIntegerListExtensions
{
    public static void Add(this IList<BigInteger> list,
        params byte[] value)
    {
        list.Add(new BigInteger(value));
    }

    public static void Add(this IList<BigInteger> list,
        string value)
    {
        list.Add(BigInteger.Parse(value));
    }
}

var bigNumbers = new List<BigInteger>
{
    new BigInteger(1), // constructor BigInteger(int)
    2222222222L,       // implicit operator BigInteger(long)
    3333333333UL,      // implicit operator BigInteger(ulong)
    { 4, 4, 4, 4, 4, 4, 4, 4 },               // extension Add(byte[])
    "55555555555555555555555555555555555555", // extension Add(string)
};

C# 7 will be adding in support for tuples built into the language, though they will be of a different type (System.ValueTuple instead). So to it would be good to add overloads for value tuples so you have the option to use them as well. Unfortunately, there are no implicit conversions defined between the two.

public static class ValueTupleListExtensions
{
    public static void Add<T1, T2>(this IList<Tuple<T1, T2>> list,
        ValueTuple<T1, T2> item) => list.Add(item.ToTuple());
}

This way the list initialization will look even nicer.

var points = new List<Tuple<int, int, int>>
{
    (0, 0, 0),
    (1, 2, 3),
    (-1, 12, -73),
};

But instead of going through all this trouble, it might just be better to switch to using ValueTuple exclusively.

var points = new List<(int, int, int)>
{
    (0, 0, 0),
    (1, 2, 3),
    (-1, 12, -73),
};

Andrea solution is absolutely right, I will just write another implementation based on the same idea. If you took a look at the THREE.ImageUtils.loadTexture() source you will find it uses the javascript Image object. The $(window).load event is fired after all Images are loaded ! so at that event we can render our scene with the textures already loaded...

• CoffeeScript

  $(document).ready ->
  
      material = new THREE.MeshLambertMaterial(map: THREE.ImageUtils.loadTexture("crate.gif"))
  
      sphere   = new THREE.Mesh(new THREE.SphereGeometry(radius, segments, rings), material)
  
      $(window).load ->
          renderer.render scene, camera
  

• JavaScript

  $(document).ready(function() {
  
      material = new THREE.MeshLambertMaterial({ map: THREE.ImageUtils.loadTexture("crate.gif") });
  
      sphere = new THREE.Mesh(new THREE.SphereGeometry(radius, segments, rings), material);
  
      $(window).load(function() {
          renderer.render(scene, camera);
      });
  });
  

Thanks...

As smnbss comments in Darin Dimitrov's answer, Prompt exists for exactly this purpose, so there is no need to create a custom attribute. From the the documentation:

Gets or sets a value that will be used to set the watermark for prompts in the UI.

To use it, just decorate your view model's property like so:

[Display(Prompt = "numbers only")]
public int Age { get; set; }

This text is then conveniently placed in ModelMetadata.Watermark. Out of the box, the default template in MVC 3 ignores the Watermark property, but making it work is really simple. All you need to do is tweaking the default string template, to tell MVC how to render it. Just edit String.cshtml, like Darin does, except that rather than getting the watermark from ModelMetadata.AdditionalValues, you get it straight from ModelMetadata.Watermark:

~/Views/Shared/EditorTemplates/String.cshtml:

@Html.TextBox("", ViewData.TemplateInfo.FormattedModelValue, new { @class = "text-box single-line", placeholder = ViewData.ModelMetadata.Watermark })

And that is it.

As you can see, the key to make everything work is the placeholder = ViewData.ModelMetadata.Watermark bit.

If you also want to enable watermarking for multi-line textboxes (textareas), you do the same for MultilineText.cshtml:

~/Views/Shared/EditorTemplates/MultilineText.cshtml:

@Html.TextArea("", ViewData.TemplateInfo.FormattedModelValue.ToString(), 0, 0, new { @class = "text-box multi-line", placeholder = ViewData.ModelMetadata.Watermark })

Because if none of the if statements evaluate to true then the local variable will be unassigned. Throw an else statement in there and assign some values to those variables in case the if statements don't evaluate to true. Post back here if that doesn't make the error go away.

Your other option is to initialize the variables to some default value when you declare them at the beginning of your code.

After trying several solutions, this worked for me:

1. Go to IIS Manager
2. Open the Site
3. Click on Authentication
4. Edit Anonymous Authentication.
5. Select "Application pool identity"

example

Had the same issue where query:

SELECT * FROM 'column' WHERE 'column' IS NULL; 

returned no values. Seems to be an issue with MyISAM and the same query on the data in InnoDB returned expected results.

Went with:

SELECT * FROM 'column' WHERE 'column' = ' '; 

Returned all expected results.

I think you are confusing objects and classes. A class inside a class looks like this:

class Foo(object):
    class Bar(object):
        pass

>>> foo = Foo()
>>> bar = Foo.Bar()

But it doesn't look to me like that's what you want. Perhaps you are after a simple containment hierarchy:

class Player(object):
    def __init__(self, ... airplanes ...) # airplanes is a list of Airplane objects
        ...
        self.airplanes = airplanes
        ...

class Airplane(object):
    def __init__(self, ... flights ...) # flights is a list of Flight objects
        ...
        self.flights = flights
        ...

class Flight(object):
    def __init__(self, ... duration ...)
        ...
        self.duration = duration
        ...

Then you can build and use the objects thus:

player = Player(...[
    Airplane(... [
        Flight(...duration=10...),
        Flight(...duration=15...),
        ] ... ),
    Airplane(...[
        Flight(...duration=20...),
        Flight(...duration=11...),
        Flight(...duration=25...),
        ]...),
    ])

player.airplanes[5].flights[6].duration = 5

A little more robust version of what you're attempting:

str = str.replaceAll("(\r\n|\n\r|\r|\n)", "<br />");

I have got a solution without using floats!
check this on codepen

Viz.

dl.inline dd {
  display: inline;
  margin: 0;
}
dl.inline dd:after{
  display: block;
  content: '';
}
dl.inline dt{
  display: inline-block;
  min-width: 100px;
}

Update - 3^rd Jan 2017: I have added flex-box based solution for the problem. Check that in the linked codepen & refine it as per needs. Thanks!

dl.inline-flex {
  display: flex;
  flex-flow: row;
  flex-wrap: wrap;
  width: 300px;      /* set the container width*/
  overflow: visible;
}
dl.inline-flex dt {
  flex: 0 0 50%;
  text-overflow: ellipsis;
  overflow: hidden;
}
dl.inline-flex dd {
  flex:0 0 50%;
  margin-left: auto;
  text-align: left;
  text-overflow: ellipsis;
  overflow: hidden;
}

Extending the above post by Tom, if you need a class type declaration and access the singleton instance using a variable, the code below might be of help. I like this notation as the code is little self guiding.

function SingletonClass(){
    if ( arguments.callee.instance )
        return arguments.callee.instance;
    arguments.callee.instance = this;
}


SingletonClass.getInstance = function() {
    var singletonClass = new SingletonClass();
    return singletonClass;
};

To access the singleton, you would

var singleTon = SingletonClass.getInstance();

You may want to double check the authorized_keys file permissions:

$ chmod 600 ~/.ssh/authorized_keys

Newer SSH server versions are very picky on this respect.

The answers above are really complete, but if you want a quick and dirty header to copy'n paste, use this:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

"""Module documentation goes here
   and here
   and ...
"""

Why this is a good one:

• The first line is for *nix users. It will choose the Python interpreter in the user path, so will automatically choose the user preferred interpreter.
• The second one is the file encoding. Nowadays every file must have a encoding associated. UTF-8 will work everywhere. Just legacy projects would use other encoding.
• And a very simple documentation. It can fill multiple lines.

See also: https://www.python.org/dev/peps/pep-0263/

If you just write a class in each file, you don't even need the documentation (it would go inside the class doc).

If we define dx = x2 - x1 and dy = y2 - y1, then the normals are (-dy, dx) and (dy, -dx).

Note that no division is required, and so you're not risking dividing by zero.

You can project 3D point in 2D using: Commons Math: The Apache Commons Mathematics Library with just two classes.

Example for Java Swing.

import org.apache.commons.math3.geometry.euclidean.threed.Plane;
import org.apache.commons.math3.geometry.euclidean.threed.Vector3D;


Plane planeX = new Plane(new Vector3D(1, 0, 0));
Plane planeY = new Plane(new Vector3D(0, 1, 0)); // Must be orthogonal plane of planeX

void drawPoint(Graphics2D g2, Vector3D v) {
    g2.drawLine(0, 0,
            (int) (world.unit * planeX.getOffset(v)),
            (int) (world.unit * planeY.getOffset(v)));
}

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

    drawPoint(g2, new Vector3D(2, 1, 0));
    drawPoint(g2, new Vector3D(0, 2, 0));
    drawPoint(g2, new Vector3D(0, 0, 2));
    drawPoint(g2, new Vector3D(1, 1, 1));
}

Now you only needs update the planeX and planeY to change the perspective-projection, to get things like this:

I just spent the better part of 3 days wrestling with this. I'm working on an application that loads other applications into itself while maintaining a fixed header and a fixed footer. Here's what I've come up with. (I also used EasyXDM, with success, but pulled it out later to use this solution.)

Make sure to run this code AFTER the <iframe> exists in the DOM. Put it into the page that pulls in the iframe (the parent).

// get the iframe
var theFrame = $("#myIframe");
// set its height to the height of the window minus the combined height of fixed header and footer
theFrame.height(Number($(window).height()) - 80);

function resizeIframe() {
    theFrame.height(Number($(window).height()) - 80);
}

// setup a resize method to fire off resizeIframe.
// use timeout to filter out unnecessary firing.
var TO = false;
$(window).resize(function() {
    if (TO !== false) clearTimeout(TO);
    TO = setTimeout(resizeIframe, 500); //500 is time in miliseconds
});

Here is some Java code that worked for me:

boolean liesOnSegment(Coordinate a, Coordinate b, Coordinate c) {
        
    double dotProduct = (c.x - a.x) * (c.x - b.x) + (c.y - a.y) * (c.y - b.y);
    return (dotProduct < 0);
}

In short: It's a shorthand notation for a mathematical hack.

Long explanation:

You can't do a cross product with vectors in 2D space. The operation is not defined there.

However, often it is interesting to evaluate the cross product of two vectors assuming that the 2D vectors are extended to 3D by setting their z-coordinate to zero. This is the same as working with 3D vectors on the xy-plane.

If you extend the vectors that way and calculate the cross product of such an extended vector pair you'll notice that only the z-component has a meaningful value: x and y will always be zero.

That's the reason why the z-component of the result is often simply returned as a scalar. This scalar can for example be used to find the winding of three points in 2D space.

From a pure mathematical point of view the cross product in 2D space does not exist, the scalar version is the hack and a 2D cross product that returns a 2D vector makes no sense at all.

You need to take out your suffix rule (%.o: %.c) in favour of a big-bang rule. Something like this:

LIBS  = -lkernel32 -luser32 -lgdi32 -lopengl32
CFLAGS = -Wall

OBJ = 64bitmath.o    \
      monotone.o     \
      node_sort.o    \
      planesweep.o   \
      triangulate.o  \
      prim_combine.o \
      welding.o      \
      test.o         \
      main.o

SRCS = $(OBJ:%.o=%.c)

test: $(SRCS)
    gcc -o $@  $(CFLAGS) $(LIBS) $(SRCS)

If you're going to experiment with GCC's whole-program optimization, make sure that you add the appropriate flag to CFLAGS, above.

On reading through the docs for those flags, I see notes about link-time optimization as well; you should investigate those too.

i assume you are working with nullable datatypes, you can do something like this:

var t = things.Where(x => x!=null && x.Value.ID == long.Parse(options.ID)).FirstOrDefault();
var res = t == null ? "" : t.Value;

{ "scripts" :
  { "build": "node build.js"}
}

npm run build OR npm run-script build

{
  "name": "build",
  "version": "1.0.0",
  "scripts": {
    "start": "node build.js"
  }
}

npm start

NB: you were missing the { brackets } and the node command

folder structure is fine:

+ build
  - package.json
  - build.js

You can use the os Module:

var os = require("os");
os.hostname();

See http://nodejs.org/docs/latest/api/os.html#os_os_hostname

Caveats:

1. if you can work with the IP address -- Machines may have several Network Cards and unless you specify it node will listen on all of them, so you don't know on which NIC the request came in, before it comes in.

2. Hostname is a DNS matter -- Don't forget that several DNS aliases can point to the same machine.

Latest Git:

git merge --abort

This attempts to reset your working copy to whatever state it was in before the merge. That means that it should restore any uncommitted changes from before the merge, although it cannot always do so reliably. Generally you shouldn't merge with uncommitted changes anyway.

Prior to version 1.7.4:

git reset --merge

This is older syntax but does the same as the above.

Prior to version 1.6.2:

git reset --hard

which removes all uncommitted changes, including the uncommitted merge. Sometimes this behaviour is useful even in newer versions of Git that support the above commands.

I don't think this question has been completely answered yet because all of the answers only give single match examples. The OP's question demonstrates the nuances of having 2 matches as well as a substring match which should not be reported because it is not a word/token.

To match multiple occurrences, one might do something like this:

iter = re.finditer(r"\bis\b", String)
indices = [m.start(0) for m in iter]

This would return a list of the two indices for the original string.

Putting this information here for future readers' benefit.

• 401 (Unauthorized) response header -> Request authentication header

• Here are several WWW-Authenticate response headers. (The full list is at IANA: HTTP Authentication Schemes.)

  • WWW-Authenticate: Basic-> Authorization: Basic + token - Use for basic authentication
  • WWW-Authenticate: NTLM-> Authorization: NTLM + token (2 challenges)
  • WWW-Authenticate: Negotiate -> Authorization: Negotiate + token - used for Kerberos authentication
    • By the way: IANA has this angry remark about Negotiate: This authentication scheme violates both HTTP semantics (being connection-oriented) and syntax (use of syntax incompatible with the WWW-Authenticate and Authorization header field syntax).

You can set the Authorization: Basic header only when you also have the WWW-Authenticate: Basic header on your 401 challenge.

But since you have WWW-Authenticate: Negotiate this should be the case for Kerberos based authentication.

Variable-length character string having maximum length size bytes or characters. Maximum size is 4000 bytes or characters, and minimum is 1 byte or 1 character. You must specify size for VARCHAR2. BYTE indicates that the column will have byte length semantics; CHAR indicates that the column will have character semantics.

But in Oracle Databast 12c maybe 32767 (http://docs.oracle.com/database/121/SQLRF/sql_elements001.htm#SQLRF30020)

Variable-length character string having maximum length size bytes or characters. You must specify size for VARCHAR2. Minimum size is 1 byte or 1 character. Maximum size is: 32767 bytes or characters if MAX_STRING_SIZE = EXTENDED 4000 bytes or characters if MAX_STRING_SIZE = STANDARD

def digits_to_number(digits):
    return reduce(lambda x,y : x+y, map(str,digits))

print digits_to_number([1,2,3,4,5])

Well, if you're reading the data in as a list, just do np.array(map(float, list_of_strings)) (or equivalently, use a list comprehension). (In Python 3, you'll need to call list on the map return value if you use map, since map returns an iterator now.)

However, if it's already a numpy array of strings, there's a better way. Use astype().

import numpy as np
x = np.array(['1.1', '2.2', '3.3'])
y = x.astype(np.float)

There is no full package of framework yet, but it is a kickstart that might give you a way to proceed further.
As a student, I hope this helpful and please contribute to this project.

You could store key/values in Redis differently to achieve this, by just adding a prefix or namespace to your keys when you store them e.g. "hset_"

• Get a key/value GET hset_key equals to HGET hset key

• Add a key/value SET hset_key value equals to HSET hset key

• Get all keys KEYS hset_* equals to HGETALL hset

• Get all vals should be done in 2 ops, first get all keys KEYS hset_* then get the value for each key

• Add a key/value with TTL or expire which is the topic of question:

 SET hset_key value
 EXPIRE hset_key

Note: KEYS will lookup up for matching the key in the whole database which may affect on performance especially if you have big database.

Note:

• KEYS will lookup up for matching the key in the whole database which may affect on performance especially if you have big database. while SCAN 0 MATCH hset_* might be better as long as it doesn't block the server but still performance is an issue in case of big database.

• You may create a new database for storing separately these keys that you want to expire especially if they are small set of keys.

Thanks to @DanFarrell who highlighted the performance issue related to KEYS

You can install multiple Java runtimes under Windows (including Windows 7) as long as each is in their own directory.

For example, if you are running Win 7 64-bit, or Win Server 2008 R2, you may install 32-bit JRE in "C:\Program Files (x86)\Java\jre6" and 64-bit JRE in "C:\Program Files\Java\jre6", and perhaps IBM Java 6 in "C:\Program Files (x86)\IBM\Java60\jre".

The Java Control Panel app theoretically has the ability to manage multiple runtimes: Java tab >> View... button

There are tabs for User and System settings. You can add additional runtimes with Add or Find, but once you have finished adding runtimes and hit OK, you have to hit Apply in the main Java tab frame, which is not as obvious as it could be - otherwise your changes will be lost.

If you have multiple versions installed, only the main version will auto-update. I have not found a solution to this apart from the weak workaround of manually updating whenever I see an auto-update, so I'd love to know if anyone has a fix for that.

Most Java IDEs allow you to select any Java runtime on your machine to build against, but if not using an IDE, you can easily manage this using environment variables in a cmd window. Your PATH and the JAVA_HOME variable determine which runtime is used by tools run from the shell. Set the JAVA_HOME to the jre directory you want and put the bin directory into your path (and remove references to other runtimes) - with IBM you may need to add multiple bin directories. This is pretty much all the set up that the default system Java does. You can also set CLASSPATH, ANT_HOME, MAVEN_HOME, etc. to unique values to match your runtime.

I got the same error message when using sklearn with pandas. My solution is to reset the index of my dataframe df before running any sklearn code:

df = df.reset_index()

I encountered this issue many times when I removed some entries in my df, such as

df = df[df.label=='desired_one']

I had an identical problem, which I solved by restarting my Python editor and shell. I had installed pywin32 but the new modules were not picked up until the restarts.

If you've already done that, do a search in your Python installation for win32api and you should find win32api.pyd under ${PYTHON_HOME}\Lib\site-packages\win32.

Please try something like:

=IF(LEN(C1)>10,VALUE(LEFT(C1,FIND(" ",C1,8))),IF(ISTEXT(C1),DATE(RIGHT(C1,4),MID(C1,4,2),LEFT(C1,2)),C1))  

You seem to have three main possible scenarios:

1. Space-separated date with time as text (eg as A1 below)
2. Hyphen-separated date as text (eg as A2 below)
3. Formatted date index (as A4 and A5 below)

ColumnA below is formatted General and ColumnB as Date (my default setting). ColumnC also as date but with custom formatting to suit the appearances mentioned in your question.
A clue as to whether or not text format is the left or right alignment of the cells’ contents.

I am suggesting separate treatment for each of the above three main cases, so use =IF to differentiate them.

Case #1

This is longer than any of the others, so can be distinguished as having a length greater than say 10 characters, with =LEN.
In this case we want all but the last six characters but for added flexibility (for instance, in case the time element included seconds) I have chosen to count from the left rather than from the right. The problem then is that the month names may vary in length, so I have chosen to look for the space that immediately follows the year to indicate the limit for the relevant number of characters.

This with =FIND which looks for a space (" ") in C1, starting with the eighth character within C1 counting from the left, on the assumption that for this case days will be expressed as two characters and months as three or more.

Since =LEFT is a string function it returns a string, but this can be converted to a value with=VALUE.

So

=VALUE(LEFT(C1,FIND(" ",C1,8))) 

returns 40671 in this example – in Excel’s 1900 date system the date serial number for May 5, 2011.

Case #2

If the length of C1 is not greater than 10 characters, we still need to distinguish between a text entry or a value entry which I have chosen to do with =ISTEXT and, where the if condition is TRUE (as for C2) apply =DATE which takes three parameters, here provided by:

=RIGHT(C2,4)  

Takes the last four characters of C2, hence 2011 in this example.

=MID(C2,4,2) 

Starting at the fourth character, takes the next two characters of C2, hence 05 in this example (representing May).

=LEFT(C2,2))  

Takes the first two characters of C2, hence 08 in this example (representing the 8th day of the month). Date is not a text function so does not need to be wrapped in =VALUE.

Taken together

=DATE(RIGHT(C2,4),MID(C2,4,2),LEFT(C2,2)) 

also returns 40671 in this example, but from different input from Case #1.

Case #3

Is simple because already a date serial number, so just

=C2  

is sufficient.

Put the above together to cover all three cases in a single formula:

=IF(LEN(C1)>10,VALUE(LEFT(C1,FIND(" ",C1,8))),IF(ISTEXT(C1),DATE(RIGHT(C1,4),MID(C1,4,2),LEFT(C1,2)),C1))  

as applied in ColumnF (formatted to suit OP) or in General format (to show values are integers) in ColumnH:

According the CORS filter documentation:

"Spring MVC provides fine-grained support for CORS configuration through annotations on controllers. However when used with Spring Security it is advisable to rely on the built-in CorsFilter that must be ordered ahead of Spring Security’s chain of filters"

Something like this will allow GET access to the /ajaxUri:

@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class AjaxCorsFilter extends CorsFilter {
    public AjaxCorsFilter() {
        super(configurationSource());
    }

    private static UrlBasedCorsConfigurationSource configurationSource() {
        CorsConfiguration config = new CorsConfiguration();

        // origins
        config.addAllowedOrigin("*");

        // when using ajax: withCredentials: true, we require exact origin match
        config.setAllowCredentials(true);

        // headers
        config.addAllowedHeader("x-requested-with");

        // methods
        config.addAllowedMethod(HttpMethod.OPTIONS);
        config.addAllowedMethod(HttpMethod.GET);

        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/startAsyncAuthorize", config);
        source.registerCorsConfiguration("/ajaxUri", config);
        return source;
    }
}

Of course, your SpringSecurity configuration must allow access to the URI with the listed methods. See @Hendy Irawan answer.

You can also use the hmisc package that will give you the following percentiles:

In my case, I just close all instance and copy my root application folder and paste it in different location then open solution in VS it works....

@Prashant Tukadiya answer works. But if you want to save the value in UserDefaults and then compare it to other date you get yout int64 truncated so it can cause problems. I found a solution.

Swift 4:

You can save int64 as string in UserDefaults:

let value: String(Date().millisecondsSince1970)
let stringValue = String(value)
UserDefaults.standard.set(stringValue, forKey: "int64String")

Like that you avoid Int truncation.

And then you can recover the original value:

let int64String = UserDefaults.standard.string(forKey: "int64String")
let originalValue = Int64(int64String!)

This allow you to compare it with other date values:

let currentTime = Date().millisecondsSince1970
let int64String = UserDefaults.standard.string(forKey: "int64String")
let originalValue = Int64(int64String!) ?? 0 

if currentTime < originalValue {
     return false
} else {
     return true
}

Hope this helps someone who has same problem

Add a try/catch block, if the transaction succeeds it will commit the changes, if the transaction fails the transaction is rolled back:

BEGIN TRANSACTION [Tran1]

  BEGIN TRY

      INSERT INTO [Test].[dbo].[T1] ([Title], [AVG])
      VALUES ('Tidd130', 130), ('Tidd230', 230)

      UPDATE [Test].[dbo].[T1]
      SET [Title] = N'az2' ,[AVG] = 1
      WHERE [dbo].[T1].[Title] = N'az'

      COMMIT TRANSACTION [Tran1]

  END TRY

  BEGIN CATCH

      ROLLBACK TRANSACTION [Tran1]

  END CATCH  

Looking forward to Web Animations in 2020.

Add all event listeners when a window loads.Works like a charm no matter where you put script tags.

window.addEventListener("load", startup);

function startup() {

  document.getElementById("el").addEventListener("click", myFunc);
  document.getElementById("el2").addEventListener("input", myFunc);

}

myFunc(){}

You can do it that way:

• Create a directory where you want to install composer (let's say /home/your_username/composer)
• Go to this directory - cd /home/your_username/composer

• Then run the following command:

  php -r "readfile('https://getcomposer.org/installer');" | php

• After that if you want to run composer, you can do it this way (in this caseyou must be in the composer's dir): php composer.phar

• As a next step, you can do this:

  alias composer="/home/your_username/composer/composer.phar".

  And run commands like you do it normally: $ composer install

Hope that helps

1. change it in solution (right Click) -> property -> web tab
2. Click Create Virtual Directory (in front of project Url textbox)

For excellent code-readability, Fest Assertions has nice support for asserting lists

So in this case, something like:

Assertions.assertThat(returnedComponents).containsExactly("One", "Two", "Three");

Or make the expected list to an array, but I prefer the above approach because it's more clear.

Assertions.assertThat(returnedComponents).containsExactly(argumentComponents.toArray());

You are calling:

JSON.parse(scatterSeries)

But when you defined scatterSeries, you said:

var scatterSeries = []; 

When you try to parse it as JSON it is converted to a string (""), which is empty, so you reach the end of the string before having any of the possible content of a JSON text.

scatterSeries is not JSON. Do not try to parse it as JSON.

data is not JSON either (getJSON will parse it as JSON automatically).

ch is JSON … but shouldn't be. You should just create a plain object in the first place:

var ch = {
    "name": "graphe1",
    "items": data.results[1]
};

scatterSeries.push(ch);

In short, for what you are doing, you shouldn't have JSON.parse anywhere in your code. The only place it should be is in the jQuery library itself.

Here is what needs to go in D1: =VLOOKUP(C1, $A$1:$B$4, 2, FALSE)

You should then be able to copy this down to the rest of column D.

I am providing a code snippet of RestTemplate GET method with path param example

public ResponseEntity<String> getName(int id) {
    final String url = "http://localhost:8080/springrestexample/employee/name?id={id}";
    Map<String, String> params = new HashMap<String, String>();
    params.put("id", id);
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    HttpEntity request = new HttpEntity(headers);
    ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.GET, String.class, params);
    return response;
}

You can convert most of the columns by just calling convert_objects:

In [36]:

df = df.convert_objects(convert_numeric=True)
df.dtypes
Out[36]:
Date         object
WD            int64
Manpower    float64
2nd          object
CTR          object
2ndU        float64
T1            int64
T2          int64
T3           int64
T4        float64
dtype: object

For column '2nd' and 'CTR' we can call the vectorised str methods to replace the thousands separator and remove the '%' sign and then astype to convert:

In [39]:

df['2nd'] = df['2nd'].str.replace(',','').astype(int)
df['CTR'] = df['CTR'].str.replace('%','').astype(np.float64)
df.dtypes
Out[39]:
Date         object
WD            int64
Manpower    float64
2nd           int32
CTR         float64
2ndU        float64
T1            int64
T2            int64
T3            int64
T4           object
dtype: object
In [40]:

df.head()
Out[40]:
        Date  WD  Manpower   2nd   CTR  2ndU   T1    T2   T3     T4
0   2013/4/6   6       NaN  2645  5.27  0.29  407   533  454    368
1   2013/4/7   7       NaN  2118  5.89  0.31  257   659  583    369
2  2013/4/13   6       NaN  2470  5.38  0.29  354   531  473    383
3  2013/4/14   7       NaN  2033  6.77  0.37  396   748  681    458
4  2013/4/20   6       NaN  2690  5.38  0.29  361   528  541    381

Or you can do the string handling operations above without the call to astype and then call convert_objects to convert everything in one go.

Since version 0.17.0 convert_objects is deprecated and there isn't a top-level function to do this so you need to do:

df.apply(lambda col:pd.to_numeric(col, errors='coerce'))

See the docs and this related question: pandas: to_numeric for multiple columns

This is the best possible way that I have tried out. If it should help anyone...

+ (UIViewController*) topMostController
{
    UIViewController *topController = [UIApplication sharedApplication].keyWindow.rootViewController;

    while (topController.presentedViewController) {
        topController = topController.presentedViewController;
    }

    return topController;
}

I don't think all the other answerers understood the question correctly. The question requires disabling editing part of the text. One solution I can think of is simulating a textbox with a fixed prefix which is not part of the textarea or input.

An example of this approach is:

<div style="border:1px solid gray; color:#999999; font-family:arial; font-size:10pt; width:200px; white-space:nowrap;">Default Notes<br/>
<textarea style="border:0px solid black;" cols="39" rows="5"></textarea></div>

The other approach, which I end up using is using JS and JQuery to simulate "Disable" feature. Example with pseudo-code (cannot be specific cause of legal issue):

  // disable existing notes by preventing keystroke
  document.getElementById("txtNotes").addEventListener('keydown', function (e) {
    if (cursorLocation < defaultNoteLength ) {
            e.preventDefault();
  });

    // disable existing notes by preventing right click
    document.addEventListener('contextmenu', function (e) {
        if (cursorLocation < defaultNoteLength )
            e.preventDefault();
    });

Thanks, Carsten, for mentioning that this question is old, but I found that the solution might help other people in the future.

The reason ++i can be slightly faster than i++ is that i++ can require a local copy of the value of i before it gets incremented, while ++i never does. In some cases, some compilers will optimize it away if possible... but it's not always possible, and not all compilers do this.

I try not to rely too much on compilers optimizations, so I'd follow Ryan Fox's advice: when I can use both, I use ++i.

I was able to select (check) a radio input button by using this Javascript code in Firefox 72, within a Web Extension option page to LOAD the value:

var reloadItem = browser.storage.sync.get('reload_mode');
reloadItem.then((response) => {
    if (response["reload_mode"] == "Periodic") {
        document.querySelector('input[name=reload_mode][value="Periodic"]').click();
    } else if (response["reload_mode"] == "Page Bottom") {
        document.querySelector('input[name=reload_mode][value="Page Bottom"]').click();
    } else {
        document.querySelector('input[name=reload_mode][value="Both"]').click();
    }
});

Where the associated code to SAVE the value was:

reload_mode: document.querySelector('input[name=reload_mode]:checked').value

Given HTML like the following:

    <input type="radio" id="periodic" name="reload_mode" value="Periodic">
    <label for="periodic">Periodic</label><br>
    <input type="radio" id="bottom" name="reload_mode" value="Page Bottom">
    <label for="bottom">Page Bottom</label><br>
    <input type="radio" id="both" name="reload_mode" value="Both">
    <label for="both">Both</label></br></br>

You have to manually copy each key/value pair to a new map. This is a loop that people have to reprogram any time they want a deep copy of a map.

You can automatically generate the function for this by installing mapper from the maps package using

go get -u github.com/drgrib/maps/cmd/mapper

and running

mapper -types string:aStruct

which will generate the file map_float_astruct.go containing not only a (deep) Copy for your map but also other "missing" map functions ContainsKey, ContainsValue, GetKeys, and GetValues:

func ContainsKeyStringAStruct(m map[string]aStruct, k string) bool {
    _, ok := m[k]
    return ok
}

func ContainsValueStringAStruct(m map[string]aStruct, v aStruct) bool {
    for _, mValue := range m {
        if mValue == v {
            return true
        }
    }

    return false
}

func GetKeysStringAStruct(m map[string]aStruct) []string {
    keys := []string{}

    for k, _ := range m {
        keys = append(keys, k)
    }

    return keys
}

func GetValuesStringAStruct(m map[string]aStruct) []aStruct {
    values := []aStruct{}

    for _, v := range m {
        values = append(values, v)
    }

    return values
}

func CopyStringAStruct(m map[string]aStruct) map[string]aStruct {
    copyMap := map[string]aStruct{}

    for k, v := range m {
        copyMap[k] = v
    }

    return copyMap
}

Full disclosure: I am the creator of this tool. I created it and its containing package because I found myself constantly rewriting these algorithms for the Go map for different type combinations.

Formally, the correct answer is the @eumiro Solution. The problem of @HYRY solution is that when you have a sequence of numbers like [1,2,3,4] the solution is wrong, i. e., you don't have the mode. Example:

>>> import pandas as pd
>>> df = pd.DataFrame(
        {
            'client': ['A', 'B', 'A', 'B', 'B', 'C', 'A', 'D', 'D', 'E', 'E', 'E', 'E', 'E', 'A'], 
            'total': [1, 4, 3, 2, 4, 1, 2, 3, 5, 1, 2, 2, 2, 3, 4], 
            'bla': [10, 40, 30, 20, 40, 10, 20, 30, 50, 10, 20, 20, 20, 30, 40]
        }
    )

If you compute like @HYRY you obtain:

>>> print(df.groupby(['client']).agg(lambda x: x.value_counts().index[0]))
        total  bla
client            
A           4   30
B           4   40
C           1   10
D           3   30
E           2   20

Which is clearly wrong (see the A value that should be 1 and not 4) because it can't handle with unique values.

Thus, the other solution is correct:

>>> import scipy.stats
>>> print(df.groupby(['client']).agg(lambda x: scipy.stats.mode(x)[0][0]))
        total  bla
client            
A           1   10
B           4   40
C           1   10
D           3   30
E           2   20

Including the header afxwin.h signalizes use of MFC. The following instructions (based on those on CodeProject.com) could help to get MFC code compiling:

1. Download and install the Windows Driver Kit.

2. Select menu Tools > Options… > Projects and Solutions > VC++ Directories.

3. In the drop-down menu Show directories for select Include files.

4. Add the following paths (replace $(WDK_directory) with the directory where you installed Windows Driver Kit in the first step):

   $(WDK_directory)\inc\mfc42
   $(WDK_directory)\inc\atl30
   

   

5. In the drop-down menu Show directories for select Library files and add (replace $(WDK_directory) like before):

   $(WDK_directory)\lib\mfc\i386
   $(WDK_directory)\lib\atl\i386
   

   

6. In the $(WDK_directory)\inc\mfc42\afxwin.inl file, edit the following lines (starting from 1033):

   _AFXWIN_INLINE CMenu::operator==(const CMenu& menu) const
       { return ((HMENU) menu) == m_hMenu; }
   _AFXWIN_INLINE CMenu::operator!=(const CMenu& menu) const
       { return ((HMENU) menu) != m_hMenu; }
   

   to

   _AFXWIN_INLINE BOOL CMenu::operator==(const CMenu& menu) const
       { return ((HMENU) menu) == m_hMenu; }
   _AFXWIN_INLINE BOOL CMenu::operator!=(const CMenu& menu) const
       { return ((HMENU) menu) != m_hMenu; }
   

   In other words, add BOOL after _AFXWIN_INLINE.

You can try this code this works fine for me:

    NotificationCompat.Builder mBuilder= new NotificationCompat.Builder(this);

    Intent i = new Intent(noti.this, Xyz_activtiy.class);
    PendingIntent pendingIntent= PendingIntent.getActivity(this,0,i,0);

    mBuilder.setAutoCancel(true);
    mBuilder.setDefaults(NotificationCompat.DEFAULT_ALL);
    mBuilder.setWhen(20000);
    mBuilder.setTicker("Ticker");
    mBuilder.setContentInfo("Info");
    mBuilder.setContentIntent(pendingIntent);
    mBuilder.setSmallIcon(R.drawable.home);
    mBuilder.setContentTitle("New notification title");
    mBuilder.setContentText("Notification text");
    mBuilder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));

    NotificationManager notificationManager= (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(2,mBuilder.build());

To get size of viewport on load and on resize (based on SimaWB response):

function getViewport() {
    var viewportWidth = $(window).width();
    var viewportHeight = $(window).height();
    $('#viewport').html('Viewport: '+viewportWidth+' x '+viewportHeight+' px');
}

getViewport();

$(window).resize(function() {
    getViewport()
});

When you have a lot of variables that don't need escaping, you can use an autoescape block:

{% autoescape off %}
{{ something }}
{{ something_else }}
<b>{{ something_important }}</b>
{% endautoescape %}

Just a thought, but you may check the influence of a ulimit -v option.

That is not an actual solution since it would limit address space available for all process, but that would allow you to check the behavior of your application with a limited virtual memory.

If you have reason to avoid the use of the datetime module, then these functions will work.

def is_leap_year(year):
    """ if year is a leap year return True
        else return False """
    if year % 100 == 0:
        return year % 400 == 0
    return year % 4 == 0

def doy(Y,M,D):
    """ given year, month, day return day of year
        Astronomical Algorithms, Jean Meeus, 2d ed, 1998, chap 7 """
    if is_leap_year(Y):
        K = 1
    else:
        K = 2
    N = int((275 * M) / 9.0) - K * int((M + 9) / 12.0) + D - 30
    return N

def ymd(Y,N):
    """ given year = Y and day of year = N, return year, month, day
        Astronomical Algorithms, Jean Meeus, 2d ed, 1998, chap 7 """    
    if is_leap_year(Y):
        K = 1
    else:
        K = 2
    M = int((9 * (K + N)) / 275.0 + 0.98)
    if N < 32:
        M = 1
    D = N - int((275 * M) / 9.0) + K * int((M + 9) / 12.0) + 30
    return Y, M, D

You can use substr:

echo substr('a,b,c,d,e,', 0, -1);
# => 'a,b,c,d,e'

Not exactly. The h1.hc-reform > p means "any p exactly one level underneath h1.hc-reform".

What you want is h1.hc-reform + p. Of course, that might cause some issues in older versions of Internet Explorer; if you want to make the page compatible with older IEs, you'll be stuck with either adding a class manually to the paragraphs or using some JavaScript (in jQuery, for example, you could do something like $('h1.hc-reform').next('p').addClass('first-paragraph')).

The skinny is that a CPU loads data from memory addresses, stores data to memory addresses, and execute instructions sequentially out of memory addresses, with some conditional jumps in the sequence of instructions processed. Each of these three categories of instructions involves computing an address to a memory cell to be used in the machine instruction. Because machine instructions are of a variable length depending on the particular instruction involved, and because we string a variable length of them together as we build our machine code, there is a two step process involved in calculating and building any addresses.

First we laying out the allocation of memory as best we can before we can know what exactly goes in each cell. We figure out the bytes, or words, or whatever that form the instructions and literals and any data. We just start allocating memory and building the values that will create the program as we go, and note down anyplace we need to go back and fix an address. In that place we put a dummy to just pad the location so we can continue to calculate memory size. For example our first machine code might take one cell. The next machine code might take 3 cells, involving one machine code cell and two address cells. Now our address pointer is 4. We know what goes in the machine cell, which is the op code, but we have to wait to calculate what goes in the address cells till we know where that data will be located, i.e. what will be the machine address of that data.

If there were just one source file a compiler could theoretically produce fully executable machine code without a linker. In a two pass process it could calculate all of the actual addresses to all of the data cells referenced by any machine load or store instructions. And it could calculate all of the absolute addresses referenced by any absolute jump instructions. This is how simpler compilers, like the one in Forth work, with no linker.

A linker is something that allows blocks of code to be compiled separately. This can speed up the overall process of building code, and allows some flexibility with how the blocks are later used, in other words they can be relocated in memory, for example adding 1000 to every address to scoot the block up by 1000 address cells.

So what the compiler outputs is rough machine code that is not yet fully built, but is laid out so we know the size of everything, in other words so we can start to calculate where all of the absolute addresses will be located. the compiler also outputs a list of symbols which are name/address pairs. The symbols relate a memory offset in the machine code in the module with a name. The offset being the absolute distance to the memory location of the symbol in the module.

That's where we get to the linker. The linker first slaps all of these blocks of machine code together end to end and notes down where each one starts. Then it calculates the addresses to be fixed by adding together the relative offset within a module and the absolute position of the module in the bigger layout.

Obviously I've oversimplified this so you can try to grasp it, and I have deliberately not used the jargon of object files, symbol tables, etc. which to me is part of the confusion.

>>> l = [list(range(i, i+4)) for i in range(10,1,-1)]
>>> l
[[10, 11, 12, 13], [9, 10, 11, 12], [8, 9, 10, 11], [7, 8, 9, 10], [6, 7, 8, 9], [5, 6, 7, 8], [4, 5, 6, 7], [3, 4, 5, 6], [2, 3, 4, 5]]
>>> sorted(l, key=sum)
[[2, 3, 4, 5], [3, 4, 5, 6], [4, 5, 6, 7], [5, 6, 7, 8], [6, 7, 8, 9], [7, 8, 9, 10], [8, 9, 10, 11], [9, 10, 11, 12], [10, 11, 12, 13]]

The above works. Are you doing something different?

Notice that your key function is just sum; there's no need to write it explicitly.

click: WAMP icon->Apache->Apache modules->chose rewrite_module

and do restart for all services.

This should work...

var displayDate = new Date().toLocaleDateString();

alert(displayDate);

But I suspect you are trying it on something else, for example:

var displayDate = Date.now.toLocaleDateString(); // No!

alert(displayDate);

UPDATED for clarification and example

examples: http://jsfiddle.net/pxfunc/5kpeJ/

Method 1. input event

In modern browsers use the input event. This event will fire when the user is typing into a text field, pasting, undoing, basically anytime the value changed from one value to another.

In jQuery do that like this

$('#someInput').bind('input', function() { 
    $(this).val() // get the current value of the input field.
});

starting with jQuery 1.7, replace bind with on:

$('#someInput').on('input', function() { 
    $(this).val() // get the current value of the input field.
});

Method 2. keyup event

For older browsers use the keyup event (this will fire once a key on the keyboard has been released, this event can give a sort of false positive because when "w" is released the input value is changed and the keyup event fires, but also when the "shift" key is released the keyup event fires but no change has been made to the input.). Also this method doesn't fire if the user right-clicks and pastes from the context menu:

$('#someInput').keyup(function() {
    $(this).val() // get the current value of the input field.
});

Method 3. Timer (setInterval or setTimeout)

To get around the limitations of keyup you can set a timer to periodically check the value of the input to determine a change in value. You can use setInterval or setTimeout to do this timer check. See the marked answer on this SO question: jQuery textbox change event or see the fiddle for a working example using focus and blur events to start and stop the timer for a specific input field

I had the same problem. I use Ubuntu 12.04. I tried disabling ipv6.

Modify the /etc/sysctl.conf and add the following:
#disable ipv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

Then restart the machine and check. I think this may be a ipv6 issue even in Windows OS.

Reporting to an external website/database

I wanted a way to simply and automatically report errors (since users often don't) from our applications. The easiest solution I could come up with was a public URL - a web page which could take input and store it to a database - that is sent data upon an application error. (The database could then be checked by a dev or a script to know if there are new errors.)

I wrote the web page in PHP and created a mysql database, user, and table to store the data. I decided on four user variables, an id, and a timestamp. The possible variables (either included in the URL or as POST data) are:

• app (application name)
• msg (message - e.g. Exception occurred ...)
• dev (developer - e.g. Pat)
• src (source - this would come from a variable pertaining to the machine on which the app was running, e.g. Environment.MachineName or some such)
• log (a log file or verbose message)

(All of the variables are optional, but nothing is reported if none of them are set - so if you just visit the website URL nothing is sent to the db.)

To send the data to the URL, I used NLog's WebService target. (Note, I had a few problems with this target at first. It wasn't until I looked at the source that I figured out that my url could not end with a /.)

All in all, it's not a bad system for keeping tabs on external apps. (Of course, the polite thing to do is to inform your users that you will be reporting possibly sensitive data and to give them a way to opt in/out.)

MySQL stuff

(The db user has only INSERT privileges on this one table in its own database.)

CREATE TABLE `reports` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `ts` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
  `applicationName` text,
  `message` text,
  `developer` text,
  `source` text,
  `logData` longtext,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8 COMMENT='storage place for reports from external applications'

If you want it visually formatted to two decimals as a string (for output) use toFixed():

var priceString = someValue.toFixed(2);

The answer by @David has two problems:

1. It leaves the result as a floating point number, and consequently holds the possibility of displaying a particular result with many decimal places, e.g. 134.1999999999 instead of "134.20".

2. If your value is an integer or rounds to one tenth, you will not see the additional decimal value:

   var n = 1.099;

   n.toFixed(2)                            //-> "1.10"
   
   var n = 3;
   (Math.round( n * 100 )/100 ).toString() //-> "3"
   n.toFixed(2)                            //-> "3.00"
   

And, as you can see above, using toFixed() is also far easier to type. ;)

Rename the solution's corresponding .SUO file. The SUO file contains the TFS status (online/offline), amongst a host of other goodies.

Do this only if the "right-click on the solution name right at the top of the Solution Explorer and select the Go Online option" fails (because e.g. you installed VS2015 preview).

This trick does work: Adding a final element in your section of HTML with a style of clear:both;

    <div style="clear:both;"></div>

Everything before that will be included in the height.

The above methods don't work very well if your anchor is a table element or within a table (row or cell).

I had to use javascript and bind to the window hashchange event to work around this (demo):

function moveUnderNav() {
    var $el, h = window.location.hash;
    if (h) {
        $el = $(h);
        if ($el.length && $el.closest('table').length) {
            $('body').scrollTop( $el.closest('table, tr').position().top - 26 );
        }
    }
}

$(window)
    .load(function () {
        moveUnderNav();
    })
    .on('hashchange', function () {
        moveUnderNav();
    });

* Note: The hashchange event is not available in all browsers.

Simply install Win64 OpenSSL v1.0.2a or Win32 OpenSSL v1.0.2a, you can download these from http://slproweb.com/products/Win32OpenSSL.html. Works out of the box, no configuration needed.

In your case it should be:

Select convert(datetime,convert(varchar(10),GRADUATION_DATE,120)) as
'GRADUATION_DATE' from mydb

try this solution

date( 'W', strtotime( "2017-01-01 + 1 day" ) );

Try this:

catch (Throwable t) {
    logger.error("any message" + t);
    StackTraceElement[] s = t.getStackTrace();
    for(StackTraceElement e : s){
        logger.error("\tat " + e);
    }   
}

To split the difference of opinion

I prefer:

   xls.DisplayAlerts = False    
   wb.SaveAs fullFilePath, AccessMode:=xlExclusive, ConflictResolution:=xlLocalSessionChanges
   xls.DisplayAlerts = True

I ran into the same issue with Go11, just wanted to share how I did solve it for helping others just in case they run into the same issue.

I had my Go project outside $GOPATH, so I had to turned on GO111MODULE=on without this option turned on, it will give you this issue; even if you you try to build or test the whole package or directory it won't be solved without GO111MODULE=on

For case-insensitive string search, use index (or rindex) in combination with fc. This example expands on the answer by Eugene Yarmash:

use feature qw( fc ); 
my $str = "Abc"; 
my $substr = "aB"; 

print "found" if index( fc $str, fc $substr ) != -1;
# Prints: found

print "found" if rindex( fc $str, fc $substr ) != -1;
# Prints: found

$str = "Abc";
$substr = "bA";

print "found" if index( fc $str, fc $substr ) != -1;
# Prints nothing

print "found" if rindex( fc $str, fc $substr ) != -1;
# Prints nothing

Both index and rindex return -1 if the substring is not found.
And fc returns a casefolded version of its string argument, and should be used here instead of the (more familiar) uc or lc. Remember to enable this function, for example with use feature qw( fc );.

element::after { 
    display: block;
    content: " ";
}

This worked for me.

I think if I were interviewing someone who had LINQ experience, I'd possibly just ask them to explain LINQ. If they can explain deferred execution, streaming, the IEnumerable/IEnumerator interfaces, foreach, iterator blocks, expression trees (for bonus points, anyway) then they can probably cope with the rest. (Admittedly they could be "ok" developers and not "get" LINQ yet - I'm really thinking of the case where they've claimed to know enough LINQ to make it a fair question.)

In the past I've asked several of the questions already listed, and a few others:

• Difference between reference and value types
• Pass by reference vs pass by value
• IDisposable and finalizers
• Strings, immutability, character encodings
• Floating point
• Delegates
• Generics
• Nullable types

r+ The existing file is opened to the beginning for both reading and writing. w+ Same as w except both for reading and writing.

None of the aforementioned solutions worked for me. What I had to do was use a nullable int (int?) on the foreign key that was not required (or not a not null column key) and then delete some of my migrations.

Start by deleting the migrations, then try the nullable int.

Problem was both a modification and model design. No code change was necessary.

Here I want my no to limit in 4 digit like if it is 1 it should show as 0001,if it 11 it should show as 0011..Below are the code.

        reciptno=1;//Pass only integer.

        string formatted = string.Format("{0:0000}", reciptno);

        TxtRecNo.Text = formatted;//Output=0001..

I implemented this code to generate Money receipt no.

The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard. .jpeg and .jpg files are identical. JPEG images are identified with 6 different standard file name extensions:

• .jpg
• .jpeg
• .jpe
• .jif
• .jfif
• .jfi

The jpg was used in Microsoft Operating Systems when they only supported 3 chars-extensions.

The JPEG File Interchange Format (JFIF - last three extensions in my list) is an image file format standard for exchanging JPEG encoded files compliant with the JPEG Interchange Format (JIF) standard, solving some of JIF's limitations in regard. Image data in JFIF files is compressed using the techniques in the JPEG standard, hence JFIF is sometimes referred to as "JPEG/JFIF".

This answer is in three parts, see below for the official release (v3 and v4)

I couldn't even find the col-lg-push-x or pull classes in the original files for RC1 i downloaded, so check your bootstrap.css file. hopefully this is something they will sort out in RC2.

anyways, the col-push-* and pull classes did exist and this will suit your needs. Here is a demo

<div class="row">
    <div class="col-sm-5 col-push-5">
        Content B
    </div>
    <div class="col-sm-5 col-pull-5">
        Content A
    </div>
    <div class="col-sm-2">
        Content C
    </div>
</div>

EDIT: BELOW IS THE ANSWER FOR THE OFFICIAL RELEASE v3.0

Also see This blog post on the subject

• col-vp-push-x = push the column to the right by x number of columns, starting from where the column would normally render -> position: relative, on a vp or larger view-port.

• col-vp-pull-x = pull the column to the left by x number of columns, starting from where the column would normally render -> position: relative, on a vp or larger view-port.

  vp = xs, sm, md, or lg

  x = 1 thru 12

I think what messes most people up, is that you need to change the order of the columns in your HTML markup (in the example below, B comes before A), and that it only does the pushing or pulling on view-ports that are greater than or equal to what was specified. i.e. col-sm-push-5 will only push 5 columns on sm view-ports or greater. This is because Bootstrap is a "mobile first" framework, so your HTML should reflect the mobile version of your site. The Pushing and Pulling are then done on the larger screens.

• (Desktop) Larger view-ports get pushed and pulled.
• (Mobile) Smaller view-ports render in normal order.

DEMO

<div class="row">
    <div class="col-sm-5 col-sm-push-5">
        Content B
    </div>
    <div class="col-sm-5 col-sm-pull-5">
        Content A
    </div>
    <div class="col-sm-2">
        Content C
    </div>
</div>

View-port >= sm

|A|B|C|

View-port < sm

|B|
|A|
|C|

EDIT: BELOW IS THE ANSWER FOR v4.0

With v4 comes flexbox and other changes to the grid system and the push\pull classes have been removed in favor of using flexbox ordering.

• Use .order-* classes to control visual order (where * = 1 thru 12)
• This can also be grid tier specific .order-md-*
• Also .order-first (-1) and .order-last (13) avalable

<div class="row">_x000D_
  <div class="col order-2">1st yet 2nd</div>_x000D_
  <div class="col order-1">2nd yet 1st</div>_x000D_
</div>

I have come up with two statements that can divide positive and negative numbers into integers and fractions without compromising accuracy (bit overflow) and speed.

x = 100.1323 # A number to be divided into integers and fractions

# The two statement to divided a number into integers and fractions
i = int(x) # A positive or negative integer
f = (x*1e17-i*1e17)/1e17 # A positive or negative fraction

E.g. 100.1323 -> 100, 0.1323 or -100.1323 -> -100, -0.1323

Speedtest

The performance test shows that the two statements are faster than math.modf, as long as they are not put into their own function or method.

POSIX SED:

$ - match last line


{ COMMANDS } - A group of commands may be enclosed between { and } characters. This is particularly useful when you want a group of commands to be triggered by a single address (or address-range) match.

This is working for me. Which version of Flask are you using?

from flask import jsonify

...

@app.route('/test/json')
def test_json():
    list = [
            {'a': 1, 'b': 2},
            {'a': 5, 'b': 10}
           ]
    return jsonify(results = list)

TLDR if you don't want to read all these great answers :-)

Explicit:

Using DateTimeOffset because the timezone is forced to UTC+0.

Implicit:

Using DateTime where you hope everyone sticks to the unwritten rule of the timezone always being UTC+0.

(Side note for devs: explicit is always better than implicit!)

(Side side note for Java devs, C# DateTimeOffset == Java OffsetDateTime, read this: https://www.baeldung.com/java-zoneddatetime-offsetdatetime)

Assuming you want to add this path for all users on the system, add the following line to your /etc/profile.d/play.sh (and possibly play.csh, etc):

PATH=$PATH:/home/me/play
export PATH

PDOStatement::fetch returns a row from the result set. The parameter PDO::FETCH_ASSOC tells PDO to return the result as an associative array.

The array keys will match your column names. If your table contains columns 'email' and 'password', the array will be structured like:

Array
(
    [email] => '[email protected]'
    [password] => 'yourpassword'
)

To read data from the 'email' column, do:

$user['email'];

and for 'password':

$user['password'];

You can also use Yapdi:

Basic usage:

import yapdi

daemon = yapdi.Daemon()
retcode = daemon.daemonize()

# This would run in daemon mode; output is not visible
if retcode == yapdi.OPERATION_SUCCESSFUL:
print('Hello Daemon')

Use this in your server.js file

app.use(express.static('public'));

without the directory ( __dirname ) and then within your project folder create a new file and name it public then put all your static files inside it

Be careful that this will create an "alternate reality" for people who have already fetch/pulled/cloned from the remote repository. But in fact, it's quite simple:

git reset HEAD^ # remove commit locally
git push origin +HEAD # force-push the new HEAD commit

If you want to still have it in your local repository and only remove it from the remote, then you can use:

git push origin +HEAD^:<name of your branch, most likely 'master'>

As the error message states, the method used to get the F score is from the "Classification" part of sklearn - thus the talking about "labels".

Do you have a regression problem? Sklearn provides a "F score" method for regression under the "feature selection" group: http://scikit-learn.org/stable/modules/generated/sklearn.feature_selection.f_regression.html

In case you do have a classification problem, @Shovalt's answer seems correct to me.

I'd construct a new data.frame:

d <- data.frame('a' = 1:3, 'b' = c('a','b','c'), 'c' = c('d', 'e', 'f'), 'd' = c('g', 'h', 'i')) 

cols <- c( 'b' , 'c' , 'd' )

data.frame(a = d[, 'a'], x = do.call(paste, c(d[ , cols], list(sep = '-'))))

Try typing in 'cls', if that doesn't work, type 'Clear' capital C. No quotes for any. Hope this helps.

I think you should refactor your packages in more convenient hierarchy, so they are out of the base package.

But if you can't do this, try:

<context:component-scan base-package="com.example">
    ...
    <context:exclude-filter type="regex" expression="com\.example\.ignore.*"/>
</context:component-scan>

Here you could find more examples: Using filters to customize scanning

function get_attribute(){ alert( $(this).attr("data-id") ); }

Forget float, margin and html 3/5. The mail is very obsolete. You need do all with table. One line = one table. You need margin or padding ? Do another column.

Codepen

Example : i need one line with 1 One Picture of 40*40 2 One margin of 10 px 3 One text of 400px

I start my line :

<table style=" background-repeat:no-repeat; width:450px;margin:0;" cellpadding="0" cellspacing="0" border="0">
   <tr style="height:40px; width:450px; margin:0;">
     <td style="height:40px; width:40px; margin:0;">
        <img src="" style="width=40px;height40;margin:0;display:block"
     </td>
     <td style="height:40px; width:10px; margin:0;">        
     </td>
     <td style="height:40px; width:400px; margin:0;">
     <p style=" margin:0;"> my text   </p>
     </td>
   </tr>
</table>

You could include the 'ncurses' library, and use getch() instead of getchar().

Just solved this problem! I know the question is quite old, but I just had this same problem and none of the answers above helped to solve it.

Assuming the actual domain name you want to use is specified in your c:\windows\System32\drivers\etc\hosts and your configurations in apache\conf\httpd.conf and apache\conf\extra\httpd-vhots.conf are right, your problem might be the same as mine:

In Apache's htdocs directory I had a shortcut linking to the actual project I wanted to see in the browser. It turns out, Apache doesn't understand shortcuts. My solution was to create a proper symlink:

In windows, and within the httdocs directory, I ran this command in the terminal:

mklink /d ple <your project directory with index.html> 

This created a proper symlink in the httpdocs directory. After restarting the Apache service and then reloading the page, I was able to see my website up :)

Use Linq's Union:

using System.Linq;
var l1 = new List<int>() { 1,2,3,4,5 };
var l2 = new List<int>() { 3,5,6,7,8 };
var l3 = l1.Union(l2).ToList();

btw @aar doesn't have transitive dependency. you need a parameter to turn it on: Transitive dependencies not resolved for aar library using gradle

Regarding Fred the Fantastic's answer:

Not every JPEG marker between C0-CF are SOF markers; I excluded DHT (C4), DNL (C8) and DAC (CC). Note that I haven't looked into whether it is even possible to parse any frames other than C0 and C2 in this manner. However, the other ones seem to be fairly rare (I personally haven't encountered any other than C0 and C2).

Either way, this solves the problem mentioned in comments by Malandy with Bangles.jpg (DHT erroneously parsed as SOF).

The other problem mentioned with 1431588037-WgsI3vK.jpg is due to imghdr only being able detect the APP0 (EXIF) and APP1 (JFIF) headers.

This can be fixed by adding a more lax test to imghdr (e.g. simply FFD8 or maybe FFD8FF?) or something much more complex (possibly even data validation). With a more complex approach I've only found issues with: APP14 (FFEE) (Adobe); the first marker being DQT (FFDB); and APP2 and issues with embedded ICC_PROFILEs.

Revised code below, also altered the call to imghdr.what() slightly:

import struct
import imghdr

def test_jpeg(h, f):
    # SOI APP2 + ICC_PROFILE
    if h[0:4] == '\xff\xd8\xff\xe2' and h[6:17] == b'ICC_PROFILE':
        print "A"
        return 'jpeg'
    # SOI APP14 + Adobe
    if h[0:4] == '\xff\xd8\xff\xee' and h[6:11] == b'Adobe':
        return 'jpeg'
    # SOI DQT
    if h[0:4] == '\xff\xd8\xff\xdb':
        return 'jpeg'
imghdr.tests.append(test_jpeg)

def get_image_size(fname):
    '''Determine the image type of fhandle and return its size.
    from draco'''
    with open(fname, 'rb') as fhandle:
        head = fhandle.read(24)
        if len(head) != 24:
            return
        what = imghdr.what(None, head)
        if what == 'png':
            check = struct.unpack('>i', head[4:8])[0]
            if check != 0x0d0a1a0a:
                return
            width, height = struct.unpack('>ii', head[16:24])
        elif what == 'gif':
            width, height = struct.unpack('<HH', head[6:10])
        elif what == 'jpeg':
            try:
                fhandle.seek(0) # Read 0xff next
                size = 2
                ftype = 0
                while not 0xc0 <= ftype <= 0xcf or ftype in (0xc4, 0xc8, 0xcc):
                    fhandle.seek(size, 1)
                    byte = fhandle.read(1)
                    while ord(byte) == 0xff:
                        byte = fhandle.read(1)
                    ftype = ord(byte)
                    size = struct.unpack('>H', fhandle.read(2))[0] - 2
                # We are at a SOFn block
                fhandle.seek(1, 1)  # Skip `precision' byte.
                height, width = struct.unpack('>HH', fhandle.read(4))
            except Exception: #IGNORE:W0703
                return
        else:
            return

Note: Created a full answer instead of a comment, since I'm not yet allowed to.

Take it from someone who has tried it all three ways... just use a varchar(39)

The slightly less efficient storage far outweighs any benefit of having to convert it on insert/update and format it when showing it anywhere.

Java lacks coalesce operator, so your code with an explicit temporary is your best choice for an assignment with a single call.

You can use the result variable as your temporary, like this:

dinner = ((dinner = cage.getChicken()) != null) ? dinner : getFreeRangeChicken();

This, however, is hard to read.

SELECT field1 FROM OPENQUERY 
                   ([NameOfLinkedSERVER], 
                   'SELECT field1 FROM TABLENAME') 
                           WHERE field1=@someParameter T1 
                                 INNER JOIN MYSQLSERVER.DATABASE.DBO.TABLENAME           
                                 T2 ON T1.PK = T2.PK

Calendar toDayCalendar = Calendar.getInstance();
Date date1 = toDayCalendar.getTime();


Calendar tomorrowCalendar = Calendar.getInstance();
tomorrowCalendar.add(Calendar.DAY_OF_MONTH,1);
Date date2 = tomorrowCalendar.getTime();

// date1 is a present date and date2 is tomorrow date

if ( date1.compareTo(date2) < 0 ) {

  //  0 comes when two date are same,
  //  1 comes when date1 is higher then date2
  // -1 comes when date1 is lower then date2

 }

The node-mysql library automatically performs escaping when used as you are already doing. See https://github.com/felixge/node-mysql#escaping-query-values

I fixed an error like this changing the places of the routes in routes.php, for example i had something like this:

Route::resource('Mensajes', 'MensajeriaController');
Route::get('Mensajes/modificar', 'MensajeriaController@modificarEstado');

and then I put it like this:

Route::get('Mensajes/modificar', 'MensajeriaController@modificarEstado');
Route::resource('Mensajes', 'MensajeriaController');

The syntax of set item is

localStorage.setItem(key,value);

The syntax of get item is

localStorage.getItem(key); 

An example of this is:

localStorage.setItem('email','[email protected]');
    let mail = localStorage.getItem("email");
    if(mail){ 
       console.log('your email id is', mail);
    }
  }

IEnumerable<T> is an interface. You need to initiate with a concrete type (that implements IEnumerable<T>). Example:

IEnumerable<string> m_oEnum = new List<string>() { "1", "2", "3"};

Here is a simple expressjs solution if you just want to run this app locally and security is not a concern:

On your server.js or app.js file, add the following:

app.use('/local-files', express.static('/'));

That will serve your ENTIRE root directory under /local-files. Needless to say this is a really bad idea if you're planning to deploy this app anywhere other than your local machine.

Now, you can simply do:

<img src="/local-files/images/mypic.jps"/> 

note: I'm running macOS. If you're using Windows you may have to search and remove 'C:\' from the path string

to get dynamic height based on browser window. Use vh instead of %

e.g: pass following height: 100vh; to the specific div

We can use call method to use other class methods as static methods.

class _Callable:
    def __init__(self, anycallable):
        self.__call__ = anycallable

class Model:

    def get_instance(conn, table_name):

        """ do something"""

    get_instance = _Callable(get_instance)

provs_fac = Model.get_instance(connection, "users")  

First Declare a variable to store filenames (to use them later):

var myfiles = [];

Open File Dialog

$('#browseBtn').click(function() {
    $('<input type="file" multiple>').on('change', function () {
        myfiles = this.files; //save selected files to the array
        console.log(myfiles); //show them on console
    }).click();
});

i'm posting it, so it may help someone because there are no clear instructions on the internet to how to store filenames into an array!

onCreate() method gets called when activity gets created, and its called only once in whole Activity life cycle. where as onStart() is called when activity is stopped... I mean it has gone to background and its onStop() method is called by the os. onStart() may be called multiple times in Activity life cycle.More details here

This worked for me. may help some one. Turn off firewall. on RHEL 7

An elegant way to move your file to an nonexistent directory is to create the following extension to native FileInfo class:

public static class FileInfoExtension
{
    //second parameter is need to avoid collision with native MoveTo
    public static void MoveTo(this FileInfo file, string destination, bool autoCreateDirectory) { 

        if (autoCreateDirectory)
        {
            var destinationDirectory = new DirectoryInfo(Path.GetDirectoryName(destination));

            if (!destinationDirectory.Exists)
                destinationDirectory.Create();
        }

        file.MoveTo(destination);
    }
}

Then use brand new MoveTo extension:

 using <namespace of FileInfoExtension>;
 ...
 new FileInfo("some path")
     .MoveTo("target path",true);

Check Methods extension documentation.

You do not need the latex2exp package to do what you wanted to do. The following code would do the trick.

ggplot(smr, aes(Fuel.Rate, Eng.Speed.Ave., color=Eng.Speed.Max.)) + 
  geom_point() + 
  labs(title=expression("Fuel Efficiency"~(alpha*Omega)), 
color=expression(alpha*Omega), x=expression(Delta~price))

Also, some comments (unanswered as of this point) asked about putting an asterisk (*) after a Greek letter. expression(alpha~"*") works, so I suggest giving it a try.

More comments asked about getting ? Price and I find the most straightforward way to achieve that is expression(Delta~price)). If you need to add something before the Greek letter, you can also do this: expression(Indicative~Delta~price) which gets you:

• install --> "npm i --save-dev babel-cli babel-preset-es2015 babel-preset-stage-0"

next in package.json file add in scripts "start": "babel-node server.js"

    {
  "name": "node",
  "version": "1.0.0",
  "description": "",
  "main": "server.js",
  "dependencies": {
    "body-parser": "^1.18.2",
    "express": "^4.16.2",

    "start": "babel-node server.js"
  },

}

and create file for babel , in root ".babelrc"

    {
    "presets":[
        "es2015",
        "stage-0"
    ]
}

and run npm start in terminal

There is a system function called ISNUMERIC for SQL 2008 and up. An example:

SELECT myCol
FROM mTable
WHERE ISNUMERIC(myCol)<> 1;

I did a couple of quick tests and also looked further into the docs:

ISNUMERIC returns 1 when the input expression evaluates to a valid numeric data type; otherwise it returns 0.

Which means it is fairly predictable for example

-9879210433 would pass but 987921-0433 does not. $9879210433 would pass but 9879210$433 does not.

So using this information you can weed out based on the list of valid currency symbols and + & - characters.

Can place code anywhere

<input class="my_<? print 'test' ?>"  />

You will need to create a public/private key as the Jenkins user on your Jenkins server, then copy the public key to the user you want to do the deployment with on your target server.

Step 1, generate public and private key on build server as user jenkins

build1:~ jenkins$ whoami
jenkins
build1:~ jenkins$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/var/lib/jenkins/.ssh/id_rsa): 
Created directory '/var/lib/jenkins/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /var/lib/jenkins/.ssh/id_rsa.
Your public key has been saved in /var/lib/jenkins/.ssh/id_rsa.pub.
The key fingerprint is:
[...] 
The key's randomart image is:
[...]
build1:~ jenkins$ ls -l .ssh
total 2
-rw-------  1 jenkins  jenkins  1679 Feb 28 11:55 id_rsa
-rw-r--r--  1 jenkins  jenkins   411 Feb 28 11:55 id_rsa.pub 
build1:~ jenkins$ cat .ssh/id_rsa.pub
ssh-rsa AAAlskdjfalskdfjaslkdjf... [email protected]

Step 2, paste the pub file contents onto the target server.

target:~ bob$ cd .ssh
target:~ bob$ vi authorized_keys (paste in the stuff which was output above.)

Make sure your .ssh dir has permissoins 700 and your authorized_keys file has permissions 644

Step 3, configure Jenkins

1. In the jenkins web control panel, nagivate to "Manage Jenkins" -> "Configure System" -> "Publish over SSH"
2. Either enter the path of the file e.g. "var/lib/jenkins/.ssh/id_rsa", or paste in the same content as on the target server.
3. Enter your passphrase, server and user details, and you are good to go!

I try to explain this problem step by step in following example.

0) Question

I try to ask you like this :

i want to open page like facebook profile www.facebook.com/kaila.piyush

it get id from url and parse it to profile.php file and return featch data from database and show user to his profile

normally when we develope any website its link look like www.website.com/profile.php?id=username example.com/weblog/index.php?y=2000&m=11&d=23&id=5678

now we update with new style not rewrite we use www.website.com/username or example.com/weblog/2000/11/23/5678 as permalink

http://example.com/profile/userid (get a profile by the ID) 
http://example.com/profile/username (get a profile by the username) 
http://example.com/myprofile (get the profile of the currently logged-in user)

1) .htaccess

Create a .htaccess file in the root folder or update the existing one :

Options +FollowSymLinks
# Turn on the RewriteEngine
RewriteEngine On
#  Rules
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php

What does that do ?

If the request is for a real directory or file (one that exists on the server), index.php isn't served, else every url is redirected to index.php.

2) index.php

Now, we want to know what action to trigger, so we need to read the URL :

In index.php :

// index.php    

// This is necessary when index.php is not in the root folder, but in some subfolder...
// We compare $requestURL and $scriptName to remove the inappropriate values
$requestURI = explode(‘/’, $_SERVER[‘REQUEST_URI’]);
$scriptName = explode(‘/’,$_SERVER[‘SCRIPT_NAME’]);

for ($i= 0; $i < sizeof($scriptName); $i++)
{
    if ($requestURI[$i] == $scriptName[$i])
    {
        unset($requestURI[$i]);
    }
}

$command = array_values($requestURI);
With the url http://example.com/profile/19837, $command would contain :

$command = array(
    [0] => 'profile',
    [1] => 19837,
    [2] => ,
)
Now, we have to dispatch the URLs. We add this in the index.php :

// index.php

require_once("profile.php"); // We need this file
switch($command[0])
{
    case ‘profile’ :
        // We run the profile function from the profile.php file.
        profile($command([1]);
        break;
    case ‘myprofile’ :
        // We run the myProfile function from the profile.php file.
        myProfile();
        break;
    default:
        // Wrong page ! You could also redirect to your custom 404 page.
        echo "404 Error : wrong page.";
        break;
}

2) profile.php

Now in the profile.php file, we should have something like this :

// profile.php

function profile($chars)
{
    // We check if $chars is an Integer (ie. an ID) or a String (ie. a potential username)

    if (is_int($chars)) {
        $id = $chars;
        // Do the SQL to get the $user from his ID
        // ........
    } else {
        $username = mysqli_real_escape_string($char);
        // Do the SQL to get the $user from his username
        // ...........
    }

    // Render your view with the $user variable
    // .........
}

function myProfile()
{
    // Get the currently logged-in user ID from the session :
    $id = ....

    // Run the above function :
    profile($id);
}

Just my 2 cents. The below command should do the trick, as answered earlier

curl -vs google.com 2>&1

However if need to get the output to a file,

curl -vs google.com > out.txt 2>&1

should work.

Doesn't have to be; "64-bit machine" can mean many things, but typically means that the CPU has registers that big. The sizeof a type is determined by the compiler, which doesn't have to have anything to do with the actual hardware (though it typically does); in fact, different compilers on the same machine can have different values for these.

System.Text.Encoding.ChooseYourEncoding.GetString(bytes).ToCharArray();

Substitute the right encoding above: e.g.

System.Text.Encoding.UTF8.GetString(bytes).ToCharArray();

Because the storage space wasn't stomped on just yet. Don't count on that behavior.

While the above most upvoted answers definitely work, I'd suggest using a slightly different approach in some cases.

If your class has multiple properties with always the same attribute and you want to get those attributes sorted into a dictionary, here is how:

var dict = typeof(Book).GetProperties().ToDictionary(p => p.Name, p => p.GetCustomAttributes(typeof(AuthorName), false).Select(a => (AuthorName)a).FirstOrDefault());

This still uses cast but ensures that the cast will always work as you will only get the custom attributes of the type "AuthorName". If you had multiple Attributes above answers would get a cast exception.

The following should work as it calculates difference between DATE and UTCDATE for the server you are running and uses that offset to calculate the UTC equivalent of any date you pass to it. In my example, I am trying to convert UTC equivalent for '1-nov-2012 06:00' in Adelaide, Australia where UTC offset is -630 minutes, which when added to any date will result in UTC equivalent of any local date.

select DATEADD(MINUTE, DATEDIFF(MINUTE, GETDATE(), GETUTCDATE()), '1-nov-2012 06:00')

I think that it's better to use simply str_replace, like the manual says:

If you don't need fancy replacing rules (like regular expressions), you should always use this function instead of ereg_replace() or preg_replace().

<?
$badUrl = "http://www.site.com/backend.php?/c=crud&m=index&t=care";
$goodUrl = str_replace('?/', '?', $badUrl);

Sounds like you're looking to simulate the IE6 box model. You could use the CSS 3 property box-sizing: border-box to achieve this. This is supported by IE8, but for Firefox you would need to use -moz-box-sizing and for Safari/Chrome, use -webkit-box-sizing.

IE6 already computes the height wrong, so you're good in that browser, but I'm not sure about IE7, I think it will compute the height the same in quirks mode.

Just copy "editor.fontSize": 18 into your setting.json of the editor.

Pressing Control+Shift+P and then typing "settings" will allow you to easily find the user or workspace settings file.

The HTC devices have the PCSII.apk which allow them to select usb connect mode. For your device, you can set it manually:

Use SQLite Editor to open /data/data/com.android.providers.setting/databases/settings.db

open table secure

turn settings starting with mount_ums_ to 0, then restart devices.

UPDATE: If it still doesn't work, try turning on debug mode.

Use the super keyword.

Your APK file is missing . So , Clean Project >> Build APK >> Run the project .

Here is another way:

df[[i for i in list(df.columns) if i != '<your column>']]

You just pass all columns to be shown except of the one you do not want.

Found this workaround

.row {
  margin-left: 0;
  margin-right: 0;
}
[class^="col-"] > [class^="col-"]:first-child,
[class^="col-"] > [class*=" col-"]:first-child
[class*=" col-"] > [class^="col-"]:first-child,
[class*=" col-"]> [class*=" col-"]:first-child,
.row > [class^="col-"]:first-child,
.row > [class*=" col-"]:first-child{
  padding-left: 0px;
}
[class^="col-"] > [class^="col-"]:last-child,
[class^="col-"] > [class*=" col-"]:last-child
[class*=" col-"] > [class^="col-"]:last-child,
[class*=" col-"]> [class*=" col-"]:last-child,
.row > [class^="col-"]:last-child,
.row > [class*=" col-"]:last-child{
    padding-right: 0px;
}

ForEach for IEnumerables

public static class FrameworkExtensions
{
    // a map function
    public static void ForEach<T>(this IEnumerable<T> @enum, Action<T> mapFunction)
    {
        foreach (var item in @enum) mapFunction(item);
    }
}

Naive example:

var buttons = GetListOfButtons() as IEnumerable<Button>;

// click all buttons
buttons.ForEach(b => b.Click());

Cool example:

// no need to type the same assignment 3 times, just
// new[] up an array and use foreach + lambda
// everything is properly inferred by csc :-)
new { itemA, itemB, itemC }
    .ForEach(item => {
        item.Number = 1;
        item.Str = "Hello World!";
    });

Note:

This is not like Select because Select expects your function to return something as for transforming into another list.

ForEach simply allows you to execute something for each of the items without any transformations/data manipulation.

I made this so I can program in a more functional style and I was surprised that List has a ForEach while IEnumerable does not.

Put this in the codeplex project

You may use Map.entrySet() method:

for (Map.Entry entry : objectSet.entrySet())
{
    System.out.println("key: " + entry.getKey() + "; value: " + entry.getValue());
}

The most robust mechanism for listing all subclasses of a given class is currently ClassGraph, because it handles the widest possible array of classpath specification mechanisms, including the new JPMS module system. (I am the author.)

List<Class<Animal>> animals;
try (ScanResult scanResult = new ClassGraph().whitelistPackages("com.zoo.animals")
        .enableClassInfo().scan()) {
    animals = scanResult
        .getSubclasses(Animal.class.getName())
        .loadClasses(Animal.class);
}

I just spent the better part of 3 days wrestling with this. I'm working on an application that loads other applications into itself while maintaining a fixed header and a fixed footer. Here's what I've come up with. (I also used EasyXDM, with success, but pulled it out later to use this solution.)

Make sure to run this code AFTER the <iframe> exists in the DOM. Put it into the page that pulls in the iframe (the parent).

// get the iframe
var theFrame = $("#myIframe");
// set its height to the height of the window minus the combined height of fixed header and footer
theFrame.height(Number($(window).height()) - 80);

function resizeIframe() {
    theFrame.height(Number($(window).height()) - 80);
}

// setup a resize method to fire off resizeIframe.
// use timeout to filter out unnecessary firing.
var TO = false;
$(window).resize(function() {
    if (TO !== false) clearTimeout(TO);
    TO = setTimeout(resizeIframe, 500); //500 is time in miliseconds
});

You can do something like this to count from a list of things.

IList<String> names = new List<string>() { "ToString", "Format" };
IEnumerable<String> methodNames = typeof(String).GetMethods().Select(x => x.Name);

int count = methodNames.Where(x => names.Contains(x)).Count();

To count a single element

string occur = "Test1";
IList<String> words = new List<string>() {"Test1","Test2","Test3","Test1"};

int count = words.Where(x => x.Equals(occur)).Count();

This feature is called designated initializers. It is an addition to the C99 standard. However, this feature was left out of the C++11. According to The C++ Programming Language, 4th edition, Section 44.3.3.2 (C Features Not Adopted by C++):

A few additions to C99 (compared with C89) were deliberately not adopted in C++:

[1] Variable-length arrays (VLAs); use vector or some form of dynamic array

[2] Designated initializers; use constructors

The C99 grammar has the designated initializers [See ISO/IEC 9899:2011, N1570 Committee Draft - April 12, 2011]

6.7.9 Initialization

initializer:
    assignment-expression
    { initializer-list }
    { initializer-list , }
initializer-list:
    designation_opt initializer
    initializer-list , designationopt initializer
designation:
    designator-list =
designator-list:
    designator
    designator-list designator
designator:
    [ constant-expression ]
    . identifier

On the other hand, the C++11 does not have the designated initializers [See ISO/IEC 14882:2011, N3690 Committee Draft - May 15, 2013]

8.5 Initializers

initializer:
    brace-or-equal-initializer
    ( expression-list )
brace-or-equal-initializer:
    = initializer-clause
    braced-init-list
initializer-clause:
    assignment-expression
    braced-init-list
initializer-list:
    initializer-clause ...opt
    initializer-list , initializer-clause ...opt
braced-init-list:
    { initializer-list ,opt }
    { }

In order to achieve the same effect, use constructors or initializer lists:

A modern alternative:

const textToFind = 'Google';
const dd = document.getElementById ('MyDropDown');
dd.selectedIndex = [...dd.options].findIndex (option => option.text === textToFind);

Name and datatype:

USE OurDatabaseName
GO

SELECT 
    sc.name AS [Columne Name], 
    st1.name AS [User Type],
    st2.name AS [Base Type]
FROM dbo.syscolumns sc
    INNER JOIN dbo.systypes st1 ON st1.xusertype = sc.xusertype
    INNER JOIN dbo.systypes st2 ON st2.xusertype = sc.xtype
-- STEP TWO: Change OurTableName to the table name
WHERE sc.id = OBJECT_ID('OurTableName')
ORDER BY sc.colid

Or:

SELECT COLUMN_NAME AS ColumnName, DATA_TYPE AS DataType, CHARACTER_MAXIMUM_LENGTH AS CharacterLength
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'OurTableName'

CharSequence is a readable sequence of char values which implements String. it has 4 methods

1. charAt(int index)
2. length()
3. subSequence(int start, int end)
4. toString()

Please refer documentation CharSequence documentation

Note that the C and C++ standards define two kinds of implementations: freestanding and hosted.

• C90 hosted environment

Allowed forms ¹:

    int main (void)
    int main (int argc, char *argv[])

    main (void)
    main (int argc, char *argv[])
    /*... etc, similar forms with implicit int */

Comments:

The former two are explicitly stated as the allowed forms, the others are implicitly allowed because C90 allowed "implicit int" for return type and function parameters. No other form is allowed.

• C90 freestanding environment

Any form or name of main is allowed ².

• C99 hosted environment

Allowed forms ³:

    int main (void)
    int main (int argc, char *argv[])
    /* or in some other implementation-defined manner. */

Comments:

C99 removed "implicit int" so main() is no longer valid.

A strange, ambiguous sentence "or in some other implementation-defined manner" has been introduced. This can either be interpreted as "the parameters to int main() may vary" or as "main can have any implementation-defined form".

Some compilers have chosen to interpret the standard in the latter way. Arguably, one cannot easily state that they are not conforming by citing the standard in itself, since it is is ambiguous.

However, to allow completely wild forms of main() was probably(?) not the intention of this new sentence. The C99 rationale (not normative) implies that the sentence refers to additional parameters to int main ⁴.

Yet the section for hosted environment program termination then goes on arguing about the case where main does not return int ⁵. Although that section is not normative for how main should be declared, it definitely implies that main might be declared in a completely implementation-defined way even on hosted systems.

• C99 freestanding environment

Any form or name of main is allowed ⁶.

• C11 hosted environment

Allowed forms ⁷:

    int main (void)
    int main (int argc, char *argv[])
    /* or in some other implementation-defined manner. */

• C11 freestanding environment

Any form or name of main is allowed ⁸.

Note that int main() was never listed as a valid form for any hosted implementation of C in any of the above versions. In C, unlike C++, () and (void) have different meanings. The former is an obsolescent feature which may be removed from the language. See C11 future language directions:

6.11.6 Function declarators

The use of function declarators with empty parentheses (not prototype-format parameter type declarators) is an obsolescent feature.

• C++03 hosted environment

Allowed forms ⁹:

    int main ()
    int main (int argc, char *argv[])

Comments:

Note the empty parenthesis in the first form. C++ and C are different in this case, because in C++ this means that the function takes no parameters. But in C it means that it may take any parameter.

• C++03 freestanding environment

The name of the function called at startup is implementation-defined. If it is named main() it must follow the stated forms ¹⁰:

    // implementation-defined name, or 
    int main ()
    int main (int argc, char *argv[])

• C++11 hosted environment

Allowed forms ¹¹:

    int main ()
    int main (int argc, char *argv[])

Comments:

The text of the standard has been changed but it has the same meaning.

• C++11 freestanding environment

The name of the function called at startup is implementation-defined. If it is named main() it must follow the stated forms ¹²:

    // implementation-defined name, or 
    int main ()
    int main (int argc, char *argv[])

References

1. ANSI X3.159-1989 2.1.2.2 Hosted environment. "Program startup"

The function called at program startup is named main. The implementation declares no prototype for this function. It shall be defined with a return type of int and with no parameters:

    int main(void) { /* ... */ } 

or with two parameters (referred to here as argc and argv, though any names may be used, as they are local to the function in which they are declared):

    int main(int argc, char *argv[]) { /* ... */ }

2. ANSI X3.159-1989 2.1.2.1 Freestanding environment:

In a freestanding environment (in which C program execution may take place without any benefit of an operating system), the name and type of the function called at program startup are implementation-defined.

3. ISO 9899:1999 5.1.2.2 Hosted environment -> 5.1.2.2.1 Program startup

The function called at program startup is named main. The implementation declares no prototype for this function. It shall be defined with a return type of int and with no parameters:

    int main(void) { /* ... */ } 

or with two parameters (referred to here as argc and argv, though any names may be used, as they are local to the function in which they are declared):

    int main(int argc, char *argv[]) { /* ... */ }

or equivalent;9) or in some other implementation-defined manner.

4. Rationale for International Standard — Programming Languages — C, Revision 5.10. 5.1.2.2 Hosted environment --> 5.1.2.2.1 Program startup

The behavior of the arguments to main, and of the interaction of exit, main and atexit (see §7.20.4.2) has been codified to curb some unwanted variety in the representation of argv strings, and in the meaning of values returned by main.

The specification of argc and argv as arguments to main recognizes extensive prior practice. argv[argc] is required to be a null pointer to provide a redundant check for the end of the list, also on the basis of common practice.

main is the only function that may portably be declared either with zero or two arguments. (The number of other functions’ arguments must match exactly between invocation and definition.) This special case simply recognizes the widespread practice of leaving off the arguments to main when the program does not access the program argument strings. While many implementations support more than two arguments to main, such practice is neither blessed nor forbidden by the Standard; a program that defines main with three arguments is not strictly conforming (see §J.5.1.).

5. ISO 9899:1999 5.1.2.2 Hosted environment --> 5.1.2.2.3 Program termination

If the return type of the main function is a type compatible with int, a return from the initial call to the main function is equivalent to calling the exit function with the value returned by the main function as its argument;11) reaching the } that terminates the main function returns a value of 0. If the return type is not compatible with int, the termination status returned to the host environment is unspecified.

6. ISO 9899:1999 5.1.2.1 Freestanding environment

In a freestanding environment (in which C program execution may take place without any benefit of an operating system), the name and type of the function called at program startup are implementation-defined.

9. ISO 14882:2003 3.6.1 Main function

An implementation shall not predefine the main function. This function shall not be overloaded. It shall have a return type of type int, but otherwise its type is implementation-defined. All implementations shall allow both of the following definitions of main:

    int main() { /* ... */ }

and

    int main(int argc, char* argv[]) { /* ... */ }

10. ISO 14882:2003 3.6.1 Main function

It is implementation-defined whether a program in a freestanding environment is required to define a main function.

11. ISO 14882:2011 3.6.1 Main function

An implementation shall not predefine the main function. This function shall not be overloaded. It shall have a return type of type int, but otherwise its type is implementation-defined. All implementations shall allow both

— a function of () returning int and

— a function of (int, pointer to pointer to char) returning int

as the type of main (8.3.5).

And another useful command to do this (after git fetch) is:

git log origin/master ^master

This shows the commits that are in origin/master but not in master. You can also do it in opposite when doing git pull, to check what commits will be submitted to remote.

ElementTree is not too smart about namespaces. You need to give the .find(), findall() and iterfind() methods an explicit namespace dictionary. This is not documented very well:

namespaces = {'owl': 'http://www.w3.org/2002/07/owl#'} # add more as needed

root.findall('owl:Class', namespaces)

Prefixes are only looked up in the namespaces parameter you pass in. This means you can use any namespace prefix you like; the API splits off the owl: part, looks up the corresponding namespace URL in the namespaces dictionary, then changes the search to look for the XPath expression {http://www.w3.org/2002/07/owl}Class instead. You can use the same syntax yourself too of course:

root.findall('{http://www.w3.org/2002/07/owl#}Class')

If you can switch to the lxml library things are better; that library supports the same ElementTree API, but collects namespaces for you in a .nsmap attribute on elements.

This works for me.

<div style="position: relative;width:100%;">
    <div style="position:absolute;left:0px;background-color:red;width:25%;height:100px;">
      This will be on the left
    </div>

    <div style="position:absolute;right:0px;background-color:blue;width:25%;height:100px;">
      This will be on the right
    </div>
</div>

This works for me:

import SwiftyJSON

extension JSON {
    
    mutating func appendIfKeyValuePair(key: String, value: Any){
        if var dict = self.dictionaryObject {
            dict[key] = value
            self = JSON(dict)
        }
    }
}

Usage:

var data: JSON = []

data.appendIfKeyValuePair(key: "myKey", value: "myValue")

In computer programming, particularly in the C, C++, and C# programming languages, a variable or object declared with the volatile keyword usually has special properties related to optimization and/or threading. Generally speaking, the volatile keyword is intended to prevent the (pseudo)compiler from applying any optimizations on the code that assume values of variables cannot change "on their own."

If you use use the Jquery from Google CDN, seriously it will improve the performance by 5 to 10 times the one which you add into your page, which gets downloaded. And also, you will get the latest version of the Jquery files.

The difference between both files i.e. jquery.js and jquery.min.js is just the file size, due to this the files are getting downloaded faster. :)

The other answers will give you a good idea how to accomplish what you have asked for....

However

There are not many cases where this is a good idea. It is usually better to store only the filename in the database and the file on the file system.

That way your database is much smaller, can be transported around easier and more importantly is quicker to backup / restore.

You could delete the line using \b

printf("hello");
int i;
for (i=0; i<80; i++)
{
  printf("\b");
}
printf("bye");

Are you mixing C and C++? One issue that can occur is that the declarations in the .h file for a .c file need to be surrounded by:

#if defined(__cplusplus)
  extern "C" {                 // Make sure we have C-declarations in C++ programs
#endif

and:

#if defined(__cplusplus)
  }
#endif

Note: if unable / unwilling to modify the .h file(s) in question, you can surround their inclusion with extern "C":

extern "C" {
#include <abc.h>
} //extern

input { float: right; clear: both; }

This question has already accepted answer but now a days one more NoSQL DB is in trend for many of its great features. It is Couchbase; which runs as CouchbaseLite on mobile platform and Couchbase Server on your server side.

Here is some of main features of Couchbase Lite.

Couchbase Lite is a lightweight, document-oriented (NoSQL), syncable database engine suitable for embedding into mobile apps.

Lightweight means:

Embedded—the database engine is a library linked into the app, not a separate server process. Small code size—important for mobile apps, which are often downloaded over cell networks. Quick startup time—important because mobile devices have relatively slow CPUs. Low memory usage—typical mobile data sets are relatively small, but some documents might have large multimedia attachments. Good performance—exact figures depend on your data and application, of course.

Document-oriented means:

Stores records in flexible JSON format instead of requiring predefined schemas or normalization. Documents can have arbitrary-sized binary attachments, such as multimedia content. Application data format can evolve over time without any need for explicit migrations. MapReduce indexing provides fast lookups without needing to use special query languages.

Syncable means:

Any two copies of a database can be brought into sync via an efficient, reliable, proven replication algorithm. Sync can be on-demand or continuous (with a latency of a few seconds). Devices can sync with a subset of a large database on a remote server. The sync engine supports intermittent and unreliable network connections. Conflicts can be detected and resolved, with app logic in full control of merging. Revision trees allow for complex replication topologies, including server-to-server (for multiple data centers) and peer-to-peer, without data loss or false conflicts. Couchbase Lite provides native APIs for seamless iOS (Objective-C) and Android (Java) development. In addition, it includes the Couchbase Lite Plug-in for PhoneGap, which enables you to build iOS and Android apps that you develop by using familiar web-application programming techniques and the PhoneGap mobile development framework.

Use a package called concurrently.

npm i concurrently --save-dev

Then setup your npm run dev task as so:

"dev": "concurrently --kill-others \"npm run start-watch\" \"npm run wp-server\""

add automaticallyImplyLeading: false, into your Scaffold's Appbar

$emit

It dispatches an event name upwards through the scope hierarchy and notify to the registered $rootScope.Scope listeners. The event life cycle starts at the scope on which $emit was called. The event traverses upwards toward the root scope and calls all registered listeners along the way. The event will stop propagating if one of the listeners cancels it.

$broadcast

It dispatches an event name downwards to all child scopes (and their children) and notify to the registered $rootScope.Scope listeners. The event life cycle starts at the scope on which $broadcast was called. All listeners for the event on this scope get notified. Afterwards, the event traverses downwards toward the child scopes and calls all registered listeners along the way. The event cannot be canceled.

$on

It listen on events of a given type. It can catch the event dispatched by $broadcast and $emit.

Visual demo:

Demo working code, visually showing scope tree (parent/child relationship):
http://plnkr.co/edit/am6IDw?p=preview

There is no need to use entity references like &mdash, &rdquo, or &#x263a, assuming the same encoding (UTF-8) is used for files and editors as well as among teams.

Is there a reason you can't simply use "?

Use the input() built-in function to get a input line from the user.

You can read the help here.

You can use the following code to get several line at once (finishing by an empty one):

while input() != '':
    do_thing

I landed up on this page when searching for a solution for “Could not open input file” error. Here's my 2 cents for this error.

I faced this same error while because I was using parameters in my php file path like this:

/usr/bin/php -q /home/**/public_html/cron/job.php?id=1234

But I found out that this is not the proper way to do it. The proper way of sending parameters is like this:

/usr/bin/php -q /home/**/public_html/cron/job.php id=1234

Just replace the "?" with a space " ".

You can use window.location.reload(); in your componentDidMount() lifecycle method. If you are using react-router, it has a refresh method to do that.

Edit: If you want to do that after a data update, you might be looking to a re-render not a reload and you can do that by using this.setState(). Here is a basic example of it to fire a re-render after data is fetched.

import React from 'react'

const ROOT_URL = 'https://jsonplaceholder.typicode.com';
const url = `${ROOT_URL}/users`;

class MyComponent extends React.Component {
    state = {
        users: null
    }
    componentDidMount() {
        fetch(url)
            .then(response => response.json())
            .then(users => this.setState({users: users}));
    }
    render() {
        const {users} = this.state;
        if (users) {
            return (
                <ul>
                    {users.map(user => <li>{user.name}</li>)}
                </ul>
            )
        } else {
            return (<h1>Loading ...</h1>)
        }
    }
}

export default MyComponent;

I do this to get the first and last value. This works with more values too.

$a = array(
    'foo' => 400,
    'bar' => 'xyz',
);
$first = current($a);   //400
$last = end($a);    //xyz

The error should be with the params. Please verify that the params is a dictionary object. If it is just a list/tuple of arguments use only one * (*params) instead of two * (**params). This will explode the list/tuple into the proper amount of arguments.

Or, if the params is coming from some other part of code as a JSON file, please do json.loads(params), because the JSON objects sometimes behave as string and so you need to make it as a JSON using load from string (loads).

super(HStoreDictionary, self).__init__(value, **params)

Hope this helps!

The correct answer to this has already been given: no, you can't give the name of an enum, only it's value.

Nevertheless, just for fun, this will give you an enum and a lookup-table all in one and give you a means of printing it by name:

main.c:

#include "Enum.h"

CreateEnum(
        EnumerationName,
        ENUMValue1,
        ENUMValue2,
        ENUMValue3);

int main(void)
{
    int i;
    EnumerationName EnumInstance = ENUMValue1;

    /* Prints "ENUMValue1" */
    PrintEnumValue(EnumerationName, EnumInstance);

    /* Prints:
     * ENUMValue1
     * ENUMValue2
     * ENUMValue3
     */
    for (i=0;i<3;i++)
    {
        PrintEnumValue(EnumerationName, i);
    }
    return 0;
}

Enum.h:

#include <stdio.h>
#include <string.h>

#ifdef NDEBUG
#define CreateEnum(name,...) \
    typedef enum \
    { \
        __VA_ARGS__ \
    } name;
#define PrintEnumValue(name,value)
#else
#define CreateEnum(name,...) \
    typedef enum \
    { \
        __VA_ARGS__ \
    } name; \
    const char Lookup##name[] = \
        #__VA_ARGS__;
#define PrintEnumValue(name, value) print_enum_value(Lookup##name, value)
void print_enum_value(const char *lookup, int value);
#endif

Enum.c

#include "Enum.h"

#ifndef NDEBUG
void print_enum_value(const char *lookup, int value)
{
    char *lookup_copy;
    int lookup_length;
    char *pch;

    lookup_length = strlen(lookup);
    lookup_copy = malloc((1+lookup_length)*sizeof(char));
    strcpy(lookup_copy, lookup);

    pch = strtok(lookup_copy," ,");
    while (pch != NULL)
    {
        if (value == 0)
        {
            printf("%s\n",pch);
            break;
        }
        else
        {
            pch = strtok(NULL, " ,.-");
            value--;
        }
    }

    free(lookup_copy);
}
#endif

Disclaimer: don't do this.

This issue vexed me for some time. I was using reactive forms and I fixed it using this method. PS. Using Angular 9 and Material 9.

In the "ngOnInit" lifecycle hook

1) Get the object you want to set as the default from your array or object literal

const countryDefault = this.countries.find(c => c.number === '826');

Here I am grabbing the United Kingdom object from my countries array.

2) Then set the formsbuilder object (the mat-select) with the default value.

this.addressForm.get('country').setValue(countryDefault.name);

3) Lastly...set the bound value property. In my case I want the name value.

<mat-select formControlName="country">
   <mat-option *ngFor="let country of countries" [value]="country.name" >
          {{country.name}}

  </mat-option>
</mat-select>

Works like a charm. I hope it helps

return in function return execution back to caller and exit from function terminates the program.

in main function return 0 or exit(0) are same but if you write exit(0) in different function then you program will exit from that position.

returning different values like return 1 or return -1 means that program is returning error .

When exit(0) is used to exit from program, destructors for locally scoped non-static objects are not called. But destructors are called if return 0 is used.

I was having the same problem while running bulk tests for an assignment. Turns out when I relocated some iostream operations (printing to console) from class constructor to a method in class it was solved.

I assume it was something to do with iostream manipulations in the constructor.

Here is the fix:

// Before
CommandPrompt::CommandPrompt() : afs(nullptr), aff(nullptr) {
    cout << "Some text I was printing.." << endl;
};


// After
CommandPrompt::CommandPrompt() : afs(nullptr), aff(nullptr) {

};

Please feel free to explain more what the error is behind the scenes since it goes beyond my cpp knowledge.

Perhaps the easiest way would be to add an image, scale it, and set it to the JFrame/JPanel (in my case JPanel) but remember to "add" it to the container only after you've added the other children components.

    ImageIcon background=new ImageIcon("D:\\FeedbackSystem\\src\\images\\background.jpg");
    Image img=background.getImage();
    Image temp=img.getScaledInstance(500,600,Image.SCALE_SMOOTH);
    background=new ImageIcon(temp);
    JLabel back=new JLabel(background);
    back.setLayout(null);
    back.setBounds(0,0,500,600);

You can create your mask array in one step like this

mask_data = input_mask_data < 3

This creates a boolean array which can then be used as a pixel mask. Note that we haven't changed the input array (as in your code) but have created a new array to hold the mask data - I would recommend doing it this way.

>>> input_mask_data = np.random.randint(0, 5, (3, 4))
>>> input_mask_data
array([[1, 3, 4, 0],
       [4, 1, 2, 2],
       [1, 2, 3, 0]])
>>> mask_data = input_mask_data < 3
>>> mask_data
array([[ True, False, False,  True],
       [False,  True,  True,  True],
       [ True,  True, False,  True]], dtype=bool)
>>> 

Use this code to pass arraylist<customobj> to anthother Activity

firstly serialize our contact bean

public class ContactBean implements Serializable {
      //do intialization here
}

Now pass your arraylist

 Intent intent = new Intent(this,name of activity.class);
 contactBean=(ConactBean)_arraylist.get(position);
 intent.putExtra("contactBeanObj",conactBean);
 _activity.startActivity(intent);

Your resource methods won't get hit, so their headers will never get set. The reason is that there is what's called a preflight request before the actual request, which is an OPTIONS request. So the error comes from the fact that the preflight request doesn't produce the necessary headers.

For RESTeasy, you should use CorsFilter. You can see here for some example how to configure it. This filter will handle the preflight request. So you can remove all those headers you have in your resource methods.

See Also:

• HTTP access control (CORS)

Turns out that Entity Framework will assume that any class that inherits from a POCO class that is mapped to a table on the database requires a Discriminator column, even if the derived class will not be saved to the DB.

The solution is quite simple and you just need to add [NotMapped] as an attribute of the derived class.

Example:

class Person
{
    public string Name { get; set; }
}

[NotMapped]
class PersonViewModel : Person
{
    public bool UpdateProfile { get; set; }
}

Now, even if you map the Person class to the Person table on the database, a "Discriminator" column will not be created because the derived class has [NotMapped].

As an additional tip, you can use [NotMapped] to properties you don't want to map to a field on the DB.

You could use the library lxml (Note top level link is now spam) , which is a superset of ElementTree. Its tostring() method includes a parameter pretty_print - for example:

>>> print(etree.tostring(root, pretty_print=True))
<root>
  <child1/>
  <child2/>
  <child3/>
</root>

The answers by cval and Priyank Patel work great. However, be aware that some values could be unicode strings and therefore may cause the str to throw a UnicodeEncodeError error. In that case, replace the function str by the function unicode.

For example, assume the string Libië (Dutch for Libya), represented in Python as the unicode string u'Libi\xeb':

print str(u'Libi\xeb')

throws the following error:

Traceback (most recent call last):
  File "/Users/tomasz/Python/MA-CIW-Scriptie/RecreateTweets.py", line 21, in <module>
    print str(u'Libi\xeb')
UnicodeEncodeError: 'ascii' codec can't encode character u'\xeb' in position 4: ordinal not in range(128)

The following line, however, will not throw an error:

print unicode(u'Libi\xeb') # prints Libië

So, replace:

values = ','.join([str(i) for i in value_list])

by

values = ','.join([unicode(i) for i in value_list])

to be safe.

What you actually created with:

MyType[] list = []

Was fixed size array (not list) with size of 0. You can create fixed size array of size for example 4 with:

MyType[] array = new MyType[4]

But there's no add method of course.

If you create list with def it's something like creating this instance with Object (You can read more about def here). And [] creates empty ArrayList in this case.

So using def list = [] you can then append new items with add() method of ArrayList

list.add(new MyType())

Or more groovy way with overloaded left shift operator:

list << new MyType() 

I was going to try something like this:

[Range(typeof(decimal), ((double)0).ToString(), ((double)decimal.MaxValue).ToString(), ErrorMessage = "Amount must be greater than or equal to zero.")]

The problem with doing this, though, is that the compiler wants a constant expression, which disallows ((double)0).ToString(). The compiler will take

[Range(0d, (double)decimal.MaxValue, ErrorMessage = "Amount must be greater than zero.")]

Understanding that you're probably talking about a local/desktop machine and would probably like to continue talking about a local/desktop machine, I'll throw an alternative out there for you just in case it might help you or someone else:

Set up multiple virtual server instances in the cloud, and share your code between them as a git repository (or mercurial, I suppose, though I have no personal experience all you really need is something decentralized). This has the benefit of giving you as close to a production experience as possible, and if you have experience setting up servers then it's not that complicated (or expensive, if you just want to spin a server up, do what you need to do, then spin it down again, then you're talking about a few cents up to say 50 cents, up to a few bucks if you just leave it running).

I do all of my project development in the cloud these days and I've found it much simpler to manage the infrastructure than I ever did when using local/non-virtualized installs, and it makes this sort of side-by-side scenario fairly straight forward. I just wanted to throw the idea out there if you hadn't considered it.

There's some sort of bogus character at the end of that source. Try deleting the last line and adding it back.

I can't figure out exactly what's there, yet ...

edit — I think it's a zero-width space, Unicode 200B. Seems pretty weird and I can't be sure of course that it's not a Stackoverflow artifact, but when I copy/paste that last function including the complete last line into the Chrome console, I get your error.

A notorious source of such characters are websites like jsfiddle. I'm not saying that there's anything wrong with them — it's just a side-effect of something, maybe the use of content-editable input widgets.

If you suspect you've got a case of this ailment, and you're on MacOS or Linux/Unix, the od command line tool can show you (albeit in a fairly ugly way) the numeric values in the characters of the source code file. Some IDEs and editors can show "funny" characters as well. Note that such characters aren't always a problem. It's perfectly OK (in most reasonable programming languages, anyway) for there to be embedded Unicode characters in string constants, for example. The problems start happening when the language parser encounters the characters when it doesn't expect them.

For IntelliJ 2019, JDK 13 and gRPC:

Intellij IDEA -> Preferences -> Build, Execution, Deployment -> Build Tools -> Gradle -> Gradle JVM

and Select correct version.

you might also have to adding below line in your build.gradle dependencies

compileOnly group: 'javax.annotation', name: 'javax.annotation-api', version: '1.3.2'

There is no TCP API that will tell you the current state of the connection. isConnected() and isClosed() tell you the current state of your socket. Not the same thing.

1. isConnected() tells you whether you have connected this socket. You have, so it returns true.

2. isClosed() tells you whether you have closed this socket. Until you have, it returns false.

3. If the peer has closed the connection in an orderly way

   • read() returns -1
   • readLine() returns null

   • readXXX() throws EOFException for any other XXX.

   • A write will throw an IOException: 'connection reset by peer', eventually, subject to buffering delays.

4. If the connection has dropped for any other reason, a write will throw an IOException, eventually, as above, and a read may do the same thing.

5. If the peer is still connected but not using the connection, a read timeout can be used.

6. Contrary to what you may read elsewhere, ClosedChannelException doesn't tell you this. [Neither does SocketException: socket closed.] It only tells you that you closed the channel, and then continued to use it. In other words, a programming error on your part. It does not indicate a closed connection.

7. As a result of some experiments with Java 7 on Windows XP it also appears that if:

   • you're selecting on OP_READ
   • select() returns a value of greater than zero
   • the associated SelectionKey is already invalid (key.isValid() == false)

   it means the peer has reset the connection. However this may be peculiar to either the JRE version or platform.

So here is my solution (similar to John Vance's answer):

First go here and get a function to detect mobile browsers.

http://detectmobilebrowsers.com/

They have a lot of different ways to detect if you are on mobile, so find one that works with what you are using.

Your HTML page (pseudo code):

If Mobile Then
    <input id="selling-date" type="date" placeholder="YYYY-MM-DD" max="2999-12-31" min="2010-01-01" value="2015-01-01" />
else
    <input id="selling-date" type="text" class="date-picker" readonly="readonly" placeholder="YYYY-MM-DD" max="2999-12-31" min="2010-01-01" value="2015-01-01" />

JQuery:

$( ".date-picker" ).each(function() {
    var min = $( this ).attr("min");
    var max = $( this ).attr("max");
    $( this ).datepicker({ 
        dateFormat: "yy-mm-dd",  
        minDate: min,  
        maxDate: max  
    });
});

This way you can still use native date selectors in mobile while still setting the min and max dates either way.

The field for non mobile should be read only because if a mobile browser like chrome for ios "requests desktop version" then they can get around the mobile check and you still want to prevent the keyboard from showing up.

However if the field is read only it could look to a user like they cant change the field. You could fix this by changing the CSS to make it look like it isn't read only (ie change border-color to black) but unless you are changing the CSS for all input tags you will find it hard to keep the look consistent across browsers.

To get arround that I just add a calendar image button to the date picker. Just change your JQuery code a bit:

$( ".date-picker" ).each(function() {
    var min = $( this ).attr("min");
    var max = $( this ).attr("max");
    $( this ).datepicker({ 
        dateFormat: "yy-mm-dd",  
        minDate: min,  
        maxDate: max,
        showOn: "both",
        buttonImage: "images/calendar.gif",
        buttonImageOnly: true,
        buttonText: "Select date"
    });
});

Note: you will have to find a suitable image.

Demi Magus answer worked for me until Rails 5.

On Apache2/Passenger/Ruby (2.4)/Rails (5.1.6), I had to put

export SECRET_KEY_BASE=GENERATED_CODE

from Demi Magus answer in /etc/apache2/envvars, cause /etc/profile seems to be ignored.

parser.print_help()
parser.exit()

The parser.exit method also accept a status (returncode), and a message value (include a trailing newline yourself!).

an opinionated example, :)

#!/usr/bin/env python3

""" Example argparser based python file
"""

import argparse

ARGP = argparse.ArgumentParser(
    description=__doc__,
    formatter_class=argparse.RawTextHelpFormatter,

ARGP.add_argument('--example', action='store_true', help='Example Argument')


def main(argp=None):
    if argp is None:
        argp = ARGP.parse_args()  # pragma: no cover

    if 'soemthing_went_wrong' and not argp.example:
        ARGP.print_help()
        ARGP.exit(status=64, message="\nSomething went wrong, --example condition was not set\n")

Example calls:

You may use the following extension method:

public static class CharExtensions
    {
        public static int CharToInt(this char c)
        {
            if (c < '0' || c > '9')
                throw new ArgumentException("The character should be a number", "c");

            return c - '0';
        }
    }

A really easy way to do it is to create an ODBC link in EXCEL and run SP_WHO2 from there.

You can Refresh whenever you like and because it's EXCEL everything can be manipulated easily!

I got this error while using malloc() to allocate some memory to a struct * after spending some this debugging the code, I finally used free() function to free the allocated memory and subsequently the error message gone :)

It allows you to read from the standard input (mainly, the console). This SO question may helps you.

This is my solution. you can download demo on my github. https://github.com/krossford/KrossLib/tree/master/android-project

This screenshot was a demo that maxLines = 4, I think it works well.

I had similar problems and tried re-installing several times, but no joy. I was looking at installing individual packages from the ISO and all of the fiddling around - not happy at all.

I finally got it to "install" by simply selecting "repair" rather than "uninstall" in control panel / programs. It took quite a while to do the "repair" though. In the end it is installed and working.

This worked for me. It may help others - easier to try than many other options, anyway.

Finish doesn't close the app, it just closes the activity. If this is the launcher activity, then it will close your app; if not, it will go back to the previous activity.

What you can do is use onActivityResult to trigger as many finish() as needed to close all the open activities.

Easily :

<p>lorem ibsum....</p>

with styles :

p{
    background-color: #eee;
    display: inline;
}

the background sets to the whole size of the element; revise the diffrence between inline elements and block elements from here

There are many other subtle points surrounding const correctness in C++. I suppose the question here has simply been about C, but I'll give some related examples since the tag is C++ :

• You often pass large arguments like strings as TYPE const & which prevents the object from being either modified or copied. Example :

  TYPE& TYPE::operator=(const TYPE &rhs) { ... return *this; }

  But TYPE & const is meaningless because references are always const.

• You should always label class methods that do not modify the class as const, otherwise you cannot call the method from a TYPE const & reference. Example :

  bool TYPE::operator==(const TYPE &rhs) const { ... }

• There are common situations where both the return value and the method should be const. Example :

  const TYPE TYPE::operator+(const TYPE &rhs) const { ... }

  In fact, const methods must not return internal class data as a reference-to-non-const.

• As a result, one must often create both a const and a non-const method using const overloading. For example, if you define T const& operator[] (unsigned i) const;, then you'll probably also want the non-const version given by :

  inline T& operator[] (unsigned i) { return const_cast<char&>( static_cast<const TYPE&>(*this)[](i) ); }

Afaik, there are no const functions in C, non-member functions cannot themselves be const in C++, const methods might have side effects, and the compiler cannot use const functions to avoid duplicate function calls. In fact, even a simple int const & reference might witness the value to which it refers be changed elsewhere.

What worked for me was going to the article someone else had already mentioned, but keying on this piece:

application.config.backup is not created by automatic backup. The backup files are in %systemdrive%\inetpub\history directory. Automatic backup is also a Vista SP1 and above feature. More information can be found in this blog post, http://blogs.iis.net/bills/archive/2008/03/24/how-to-backup-restore-iis7-configuration.aspx

I was able to find backups of my settings from when I had first installed IIS, and just copy and replace the files in the inetsrv\config directory.
