For an easier way to use the InputTextLayout, I have created this library that cuts your XML code to less than the half, and also provides you with the ability to set an error message as well as a hint message and an easy way to do your validations. https://github.com/TeleClinic/SmartEditText

Simply add

compile 'com.github.TeleClinic:SmartEditText:0.1.0'

Then you can do something like this:

<com.teleclinic.kabdo.smartmaterialedittext.CustomViews.SmartEditText
    android:id="@+id/emailSmartEditText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:setLabel="Email"
    app:setMandatoryErrorMsg="Mandatory field"
    app:setRegexErrorMsg="Wrong email format"
    app:setRegexType="EMAIL_VALIDATION" />

<com.teleclinic.kabdo.smartmaterialedittext.CustomViews.SmartEditText
    android:id="@+id/passwordSmartEditText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:setLabel="Password"
    app:setMandatoryErrorMsg="Mandatory field"
    app:setPasswordField="true"
    app:setRegexErrorMsg="Weak password"
    app:setRegexType="MEDIUM_PASSWORD_VALIDATION" />

<com.teleclinic.kabdo.smartmaterialedittext.CustomViews.SmartEditText
    android:id="@+id/ageSmartEditText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:setLabel="Age"
    app:setMandatory="false"
    app:setRegexErrorMsg="Is that really your age :D?"
    app:setRegexString=".*\\d.*" />

I have done following and it resolve an issue with recyclerview same you may use for other widget as well if it's not working in eclipse project.

• Go to sdk\extras\android\m2repository\com\android\support\recyclerview-v7\21.0.0-rc1 directory

• Copy recyclerview-v7-21.0.0-rc1.aar file and rename it as .zip

• Unzip the file, you will get classes.jar (rename the jar file more meaningful name)

• Use the following jar in your project build path or lib directory.

and it resolve your error.

happy coding :)

You need to escape the backslash \:

println yourString.replace("\\", "/")

The height of list view items are adjusted based on its contents. In first image, no content. so height is very minimum. In second image, height is increased based on the size of the text. Because, you specified android:layout_height="wrap_content".

Here is a solution that works with Xcode 10.1 (FEB 23 2019) :

func getCurrentDateTime() {

    let now = Date()
    let formatter = DateFormatter()
    formatter.locale = Locale(identifier: "fr_FR")
    formatter.dateFormat = "EEEE dd MMMM YYYY"
    labelDate.text = formatter.string(from: now)
    labelDate.font = UIFont(name: "HelveticaNeue-Bold", size: 12)
    labelDate.textColor = UIColor.lightGray

    let text = formatter.string(from: now)
    labelDate.text = text.uppercased()
}

The "Accueil" Label is not connected to the code.

Use

docker image prune -all

or

docker image prune -a

Remove all dangling images. If -a is specified, it will also remove all images not referenced by any container.

Note: You are prompted for confirmation before the prune removes anything, but you are not shown a list of what will potentially be removed. In addition, docker image ls does not support negative filtering, so it difficult to predict what images will actually be removed.

As stated under Docker's documentation for prune.

It depends on the language, but there should be a modifier that you can add to the regex pattern. In PHP it is:

/(.*)<FooBar>/s

The s at the end causes the dot to match all characters including newlines.

foreach (DataRow dr in ds.Tables[0].Rows)
{
    //your code here
}

all:
    echo ${PATH}

Or change PATH just for one command:

all:
    PATH=/my/path:${PATH} cmd

sum(l) / float(len(l)) is the right answer, but just for completeness you can compute an average with a single reduce:

>>> reduce(lambda x, y: x + y / float(len(l)), l, 0)
20.111111111111114

Note that this can result in a slight rounding error:

>>> sum(l) / float(len(l))
20.111111111111111

Had this problem after install Git Extensions v3.48. Tried to install mysysgit again but same problem. At the end, had to disable (please consider security implications!) Git SSL verification with:

git config --global http.sslVerify false

but if you have a domain certificate better add it to (Win7)

C:\Program Files (x86)\Git\bin\curl-ca-bundle.crt

For Each row As DataGridViewRow In yourDGV.SelectedRows
    yourDGV.Rows.Remove(row)
Next

This will delete all rows that had been selected.

1D array of primitives does copy elements when it is cloned. This tempts us to clone 2D array(Array of Arrays).

Remember that 2D array clone doesn't work due to shallow copy implementation of clone().

public static void main(String[] args) {
    int row1[] = {0,1,2,3};
    int row2[] =  row1.clone();
    row2[0] = 10;
    System.out.println(row1[0] == row2[0]); // prints false

    int table1[][]={{0,1,2,3},{11,12,13,14}};
    int table2[][] = table1.clone();
    table2[0][0] = 100;
    System.out.println(table1[0][0] == table2[0][0]); //prints true
}

math.fabs() always returns float, while abs() may return integer.

You have to load the db library first. In autoload.php add :

$autoload['libraries'] = array('database');

Also, try renaming User model class for "User_model".

I normally use pip list to get a list of packages (with version).

This works in a virtual environment too, of course. To show what's installed in only the virtual environment (not global packages), use pip list --local.

Here's documentation showing all the available pip list options, with several good examples.

You could also just compile the following program and run it on your machine.

#include <gtk/gtk.h>
#include <glib/gprintf.h>

int main(int argc, char *argv[])
{
    /* Initialize GTK */
    gtk_init (&argc, &argv);

    g_printf("%d.%d.%d\n", gtk_major_version, gtk_minor_version, gtk_micro_version);
    return(0);
}

compile with ( assuming above source file is named version.c):

gcc version.c -o version `pkg-config --cflags --libs gtk+-2.0`

When you run this you will get some output. On my old embedded device I get the following:

[root@n00E04B3730DF n2]# ./version 
2.10.4
[root@n00E04B3730DF n2]#

There is a read_pickle function as part of pandas 0.22+

import pandas as pd

object = pd.read_pickle(r'filepath')

Summary:

Backticks in JavaScript is a feature which is introduced in ECMAScript 6 // ECMAScript 2015 for making easy dynamic strings. This ECMAScript 6 feature is also named template string literal. It offers the following advantages when compared to normal strings:

• In Template strings linebreaks are allowed and thus can be multiline. Normal string literals (declared with '' or "") are not allowed to have linebreaks.
• We can easily interpolate variable values to the string with the ${myVariable} syntax.

Example:

const name = 'Willem';_x000D_
const age = 26;_x000D_
_x000D_
const story = `_x000D_
  My name is: ${name}_x000D_
  And I'm: ${age} years old_x000D_
`;_x000D_
_x000D_
console.log(story);

Browser compatibility:

Template string literal are natively supported by all major browser vendors (except Internet Explorer). So it is pretty save to use in your production code. A more detailed list of the browser compatibilities can be found here.

Using android:singleLine="true" is deprecated.

Just add your input type and set maxline to 1 and everything will work fine

android:inputType="text"
android:maxLines="1"

Assuming ASCII strings:

string1 = 'Hello'
string2 = 'hello'

if string1.lower() == string2.lower():
    print("The strings are the same (case insensitive)")
else:
    print("The strings are NOT the same (case insensitive)")

As of June 2009 the originally cited blog post has a method to create animated GIFs in the comments. Download the script images2gif.py (formerly images2gif.py, update courtesy of @geographika).

Then, to reverse the frames in a gif, for instance:

#!/usr/bin/env python

from PIL import Image, ImageSequence
import sys, os
filename = sys.argv[1]
im = Image.open(filename)
original_duration = im.info['duration']
frames = [frame.copy() for frame in ImageSequence.Iterator(im)]    
frames.reverse()

from images2gif import writeGif
writeGif("reverse_" + os.path.basename(filename), frames, duration=original_duration/1000.0, dither=0)

esModuleInterop generates the helpers outlined in the docs. Looking at the generated code, we can see exactly what these do:

//ts 
import React from 'react'
//js 
var __importDefault = (this && this.__importDefault) || function (mod) {
    return (mod && mod.__esModule) ? mod : { "default": mod };
};
Object.defineProperty(exports, "__esModule", { value: true });
var react_1 = __importDefault(require("react"));

__importDefault: If the module is not an es module then what is returned by require becomes the default. This means that if you use default import on a commonjs module, the whole module is actually the default.

__importStar is best described in this PR:

TypeScript treats a namespace import (i.e. import * as foo from "foo") as equivalent to const foo = require("foo"). Things are simple here, but they don't work out if the primary object being imported is a primitive or a value with call/construct signatures. ECMAScript basically says a namespace record is a plain object.

Babel first requires in the module, and checks for a property named __esModule. If __esModule is set to true, then the behavior is the same as that of TypeScript, but otherwise, it synthesizes a namespace record where:

1. All properties are plucked off of the require'd module and made available as named imports.
2. The originally require'd module is made available as a default import.

So we get this:

// ts
import * as React from 'react'

// emitted js
var __importStar = (this && this.__importStar) || function (mod) {
    if (mod && mod.__esModule) return mod;
    var result = {};
    if (mod != null) for (var k in mod) if (Object.hasOwnProperty.call(mod, k)) result[k] = mod[k];
    result["default"] = mod;
    return result;
};
Object.defineProperty(exports, "__esModule", { value: true });
var React = __importStar(require("react"));

allowSyntheticDefaultImports is the companion to all of this, setting this to false will not change the emitted helpers (both of them will still look the same). But it will raise a typescript error if you are using default import for a commonjs module. So this import React from 'react' will raise the error Module '".../node_modules/@types/react/index"' has no default export. if allowSyntheticDefaultImports is false.

If you don't explicitly cast one of the two values to a float before doing the division then an integer division will be used (so that's why you get 0). You just need one of the two operands to be a floating point value, so that the normal division is used (and other integer value is automatically turned into a float).

Just try with

float completed = 50000.0f;

and it will be fine.

result = bytes.fromhex(some_hex_string)

press Windows key + R write "services.msc" enter search for "MYSQL56" write click on it and start the service

It is changed to : from PIL.Image import core as image for new versions.

In my case, the error was being shown because when I was reading my JSON file using Jackson library, my JSON file contained only 1 object. Hence it started with "{" and ended with "}". But while reading it and storing it in a variable, I was storing it in an Array object (As in my case, there could be more than 1 object).

Hence, I added "[" in the start and "]" in the end of my JSON file to convert it into an array of object and it worked perfectly fine without any error.

You can use

var modal_template_html = $.trim($('#modal_template').html());
var template = $(modal_template_html);

Access 2010 has both stored procedures, and also has table triggers. And, both features are available even when you not using a server (so, in 100% file based mode).

If you using SQL Server with Access, then of course the stored procedures are built using SQL Server and not Access.

For Access 2010, you open up the table (non-design view), and then choose the table tab. You see options there to create store procedures and table triggers.

For example:

Note that the stored procedure language is its own flavor just like Oracle or SQL Server (T-SQL). Here is example code to update an inventory of fruits as a result of an update in the fruit order table

Keep in mind these are true engine-level table triggers. In fact if you open up that table with VB6, VB.NET, FoxPro or even modify the table on a computer WITHOUT Access having been installed, the procedural code and the trigger at the table level will execute. So, this is a new feature of the data engine jet (now called ACE) for Access 2010. As noted, this is procedural code that runs, not just a single statement.

I'm guessing that you're doing some sort of localization, so have a look at this script.

As suggested by user7860670, right-click on the project, select properties, navigate to C/C++ -> Preprocessor and add _USE_MATH_DEFINES to the Preprocessor Definitions.

That's what worked for me.

Simple solution source='category.name' where category is foreign key and .name it's attribute.

from rest_framework.serializers import ModelSerializer, ReadOnlyField
from my_app.models import Item

class ItemSerializer(ModelSerializer):
    category_name = ReadOnlyField(source='category.name')

    class Meta:
        model = Item
        fields = "__all__"

The MOST CORRECT answer to your question is...

#content > div:first-of-type { /* css */ }

This will apply the CSS to the first div that is a direct child of #content (which may or may not be the first child element of #content)

Another option:

#content > div:nth-of-type(1) { /* css */ }

Unless you are writing a library or have special reasons, you can forget about inline and use link-time optimization instead. It removes the requirement that a function definition must be in a header for it to be considered for inlining across compilation units, which is precisely what inline allows.

(But see Is there any reason why not to use link time optimization?)

For very advanced JSON objects to HTML tables you can try My jQuery Solution that is based on this closed thread.

var myList=[{"name": "abc","age": 50},{"name": {"1": "piet","2": "jan","3": "klaas"},"age": "25","hobby": "watching tv"},{"name": "xyz","hobby": "programming","subtable": [{"a": "a","b": "b"},{"a": "a","b": "b"}]}];

// Builds the HTML Table out of myList json data from Ivy restful service.
 function buildHtmlTable() {
      addTable(myList, $("#excelDataTable"));
 }

function addTable(list, appendObj) {
    var columns = addAllColumnHeaders(list, appendObj);

    for (var i = 0; i < list.length; i++) {

you can also try lsblk ... is in util-linux ... but i have a question too

fdisk -l /dev/sdl

no result

grep sdl /proc/partitions      
   8      176   15632384 sdl
   8      177   15628288 sdl1

lsblk | grep sdl
sdl       8:176  1  14.9G  0 disk  
`-sdl1    8:177  1  14.9G  0 part  

fdisk is good but not that good ... seems like it cannot "see" everything

in my particular example i have a stick that have also a card reader build in it and i can see only the stick using fdisk:

fdisk -l /dev/sdk

Disk /dev/sdk: 15.9 GB, 15931539456 bytes
255 heads, 63 sectors/track, 1936 cylinders, total 31116288 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xbe24be24

   Device Boot      Start         End      Blocks   Id  System
/dev/sdk1   *        8192    31116287    15554048    c  W95 FAT32 (LBA)

but not the card (card being /dev/sdl)

also, file -s is inefficient ...

file -s /dev/sdl1
/dev/sdl1: sticky x86 boot sector, code offset 0x52, OEM-ID "NTFS    ", sectors/cluster 8, reserved sectors 0, Media descriptor 0xf8, heads 255, hidden sectors 8192, dos < 4.0 BootSector (0x0)

that's nice ... BUT

fdisk -l /dev/sdb
/dev/sdb1            2048   156301487    78149720   fd  Linux raid autodetect
/dev/sdb2       156301488   160086527     1892520   82  Linux swap / Solaris

file -s /dev/sdb1
/dev/sdb1: sticky \0

to see information about a disk that cannot be accesed by fdisk, you can use parted:

parted /dev/sdl print

Model: Mass Storage Device (scsi)
Disk /dev/sdl: 16.0GB
Sector size (logical/physical): 512B/512B

 2      80.0GB  82.0GB  1938MB  primary  linux-swap(v1)

You can use \t in a string literal:

"hello\talex"

You can also mix raw SQL with ActiveRecord conditions, for example if you want to call a function in a condition:

my_instances = MyModel.where.not(attribute_a: nil) \
  .where('crc32(attribute_b) = ?', slot) \
  .select(:id)

I found an another way to fix this issue in a more convenient manner:

1. Select the broken file in Solution Explorer.
2. Open its Properties.
3. Switch field "Build Action" from "Compile" to "None".
4. Then switch it back to "Compile".

This will kill the synchronization between Unity and Visual Studio somehow.

The next time Visual Studio will reload the project, it will prompt a warning. Just click on "Discard".

To formalize some of the approaches laid out above:

Create a function that operates on the rows of your dataframe like so:

def f(row):
    if row['A'] == row['B']:
        val = 0
    elif row['A'] > row['B']:
        val = 1
    else:
        val = -1
    return val

Then apply it to your dataframe passing in the axis=1 option:

In [1]: df['C'] = df.apply(f, axis=1)

In [2]: df
Out[2]:
   A  B  C
a  2  2  0
b  3  1  1
c  1  3 -1

Of course, this is not vectorized so performance may not be as good when scaled to a large number of records. Still, I think it is much more readable. Especially coming from a SAS background.

Edit

Here is the vectorized version

df['C'] = np.where(
    df['A'] == df['B'], 0, np.where(
    df['A'] >  df['B'], 1, -1))

Update 2016:

Google Chrome released the storage API: http://developer.chrome.com/extensions/storage.html

It is pretty easy to use like the other Chrome APIs and you can use it from any page context within Chrome.

    // Save it using the Chrome extension storage API.
    chrome.storage.sync.set({'foo': 'hello', 'bar': 'hi'}, function() {
      console.log('Settings saved');
    });

    // Read it using the storage API
    chrome.storage.sync.get(['foo', 'bar'], function(items) {
      message('Settings retrieved', items);
    });

To use it, make sure you define it in the manifest:

    "permissions": [
      "storage"
    ],

There are methods to "remove", "clear", "getBytesInUse", and an event listener to listen for changed storage "onChanged"

Using native localStorage (old reply from 2011)

Content scripts run in the context of webpages, not extension pages. Therefore, if you're accessing localStorage from your contentscript, it will be the storage from that webpage, not the extension page storage.

Now, to let your content script to read your extension storage (where you set them from your options page), you need to use extension message passing.

The first thing you do is tell your content script to send a request to your extension to fetch some data, and that data can be your extension localStorage:

contentscript.js

chrome.runtime.sendMessage({method: "getStatus"}, function(response) {
  console.log(response.status);
});

background.js

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
    if (request.method == "getStatus")
      sendResponse({status: localStorage['status']});
    else
      sendResponse({}); // snub them.
});

You can do an API around that to get generic localStorage data to your content script, or perhaps, get the whole localStorage array.

I hope that helped solve your problem.

To be fancy and generic ...

contentscript.js

chrome.runtime.sendMessage({method: "getLocalStorage", key: "status"}, function(response) {
  console.log(response.data);
});

background.js

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
    if (request.method == "getLocalStorage")
      sendResponse({data: localStorage[request.key]});
    else
      sendResponse({}); // snub them.
});

georg's solution is nice, but breaks if the string doesn't contain any whitespace. If your strings have a chance of not containing whitespace, it's safer to use .split and capturing groups like so:

str_1 = str.split(/\s(.+)/)[0];  //everything before the first space
str_2 = str.split(/\s(.+)/)[1];  //everything after the first space

If I may add to @Lauritz's answer

In order not to have a run error don't forget to add a condition before the bisect_left line:

if (myNumber > myList[-1] or myNumber < myList[0]):
    return False

so the full code will look like:

from bisect import bisect_left

def takeClosest(myList, myNumber):
    """
    Assumes myList is sorted. Returns closest value to myNumber.
    If two numbers are equally close, return the smallest number.
    If number is outside of min or max return False
    """
    if (myNumber > myList[-1] or myNumber < myList[0]):
        return False
    pos = bisect_left(myList, myNumber)
    if pos == 0:
            return myList[0]
    if pos == len(myList):
            return myList[-1]
    before = myList[pos - 1]
    after = myList[pos]
    if after - myNumber < myNumber - before:
       return after
    else:
       return before

I'm just writing this to remind myself...

    Array.prototype.slice.call(arguments);
==  Array.prototype.slice(arguments[1], arguments[2], arguments[3], ...)
==  [ arguments[1], arguments[2], arguments[3], ... ]

Or just use this handy function $A to turn most things into an array.

function hasArrayNature(a) {
    return !!a && (typeof a == "object" || typeof a == "function") && "length" in a && !("setInterval" in a) && (Object.prototype.toString.call(a) === "[object Array]" || "callee" in a || "item" in a);
}

function $A(b) {
    if (!hasArrayNature(b)) return [ b ];
    if (b.item) {
        var a = b.length, c = new Array(a);
        while (a--) c[a] = b[a];
        return c;
    }
    return Array.prototype.slice.call(b);
}

example usage...

function test() {
    $A( arguments ).forEach( function(arg) {
        console.log("Argument: " + arg);
    });
}

I would write the code like this:

def search_book(request):
    form = SearchForm(request.POST or None)
    if request.method == "POST" and form.is_valid():
        stitle = form.cleaned_data['title']
        sauthor = form.cleaned_data['author']
        scategory = form.cleaned_data['category']
        return HttpResponseRedirect('/thanks/')
    return render_to_response("books/create.html", {
        "form": form,
    }, context_instance=RequestContext(request))

Pretty much like the documentation.

1. crop would be a more reusable function if you separate the cropping code from the image saving code. It would also make the call signature simpler.
2. im.crop returns a Image._ImageCrop instance. Such instances do not have a save method. Instead, you must paste the Image._ImageCrop instance onto a new Image.Image
3. Your ranges do not have the right step sizes. (Why height-2 and not height? for example. Why stop at imgheight-(height/2)?).

So, you might try instead something like this:

import Image
import os

def crop(infile,height,width):
    im = Image.open(infile)
    imgwidth, imgheight = im.size
    for i in range(imgheight//height):
        for j in range(imgwidth//width):
            box = (j*width, i*height, (j+1)*width, (i+1)*height)
            yield im.crop(box)

if __name__=='__main__':
    infile=...
    height=...
    width=...
    start_num=...
    for k,piece in enumerate(crop(infile,height,width),start_num):
        img=Image.new('RGB', (height,width), 255)
        img.paste(piece)
        path=os.path.join('/tmp',"IMG-%s.png" % k)
        img.save(path)

You have to use Javascript since code behind is server side only. I am pretty sure that this works.

<asp:Button ID="btnNewEntry" runat="Server" CssClass="button" Text="New Entry" OnClick="btnNewEntry_Click" OnClientClick="aspnetForm.target ='_blank';"/>

protected void btnNewEntry_Click(object sender, EventArgs e)
{
  Response.Redirect("New.aspx");
}

Any errors show up? This might an issue of not having set the backend. You can set it from the Python interpreter or from a config file (.matplotlib/matplotlibrc) in you home directory.

To set the backend in code you can do

import matplotlib
matplotlib.use('Agg')

where 'Agg' is the name of the backend. Which backends are present depend on your installation and OS.

http://matplotlib.sourceforge.net/faq/installing_faq.html#backends

http://matplotlib.org/users/customizing.html

You have to use .onload

let canvas = document.getElementById("myCanvas");
let ctx = canvas.getContext("2d"); 

const drawImage = (url) => {
    const image = new Image();
    image.src = url;
    image.onload = () => {
       ctx.drawImage(image, 0, 0)
    }
}

Here's Why

If you are loading the image first after the canvas has already been created then the canvas won't be able to pass all the image data to draw the image. So you need to first load all the data that came with the image and then you can use drawImage()

This is because you have specified the form method as GET

Change code in the view to this:

using (@Html.BeginForm("myMethod", "Home", FormMethod.Post, new { id = @item.JobId })){
}

I can not see where do you declare context. For the purpose of the intent creation you can use MainActivity.this

 lv.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                    long id) {
                Intent intent = new Intent(MainActivity.this, SendMessage.class);
                String message = "abc";
                intent.putExtra(EXTRA_MESSAGE, message);
                startActivity(intent);
            }
        });

To retrieve the object upon you have clicked you can use the AdapterView:

ListEntry entry = (ListEntry) parent.getItemAtPosition(position);

You could also set an inputMask:

QLineEdit.setInputMask("9")

This allows the user to type only one digit ranging from 0 to 9. Use multiple 9's to allow the user to enter multiple numbers. See also the complete list of characters that can be used in an input mask.

(My answer is in Python, but it should not be hard to transform it to C++)

you can try this ts_create TIMESTAMP DEFAULT CURRENT_TIMESTAMP, ts_update TIMESTAMP DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP

@bhamby is correct. By leaving the microseconds off of your timestamp value, your query would only match on a usagetime of 2012-09-03 08:03:06.000000

If you don't have the complete timestamp value captured from a previous query, you can specify a ranged predicate that will match on any microsecond value for that time:

...WHERE id = 1 AND usagetime BETWEEN '2012-09-03 08:03:06' AND '2012-09-03 08:03:07'

or

...WHERE id = 1 AND usagetime >= '2012-09-03 08:03:06' 
   AND usagetime < '2012-09-03 08:03:07'

You want java.text.DecimalFormat

There is already a correct answer from Adam, but you have another option to refactor your code:

if (Age.GetValueOrDefault() == 0)
{
    // it's null or 0
}

Why should not use jquery popup for this purpose.I use bpopup for this purpose.See more about this.

I edited the ./bash_profile and added below command

It's probably worth noting that IE won't cache css files called by other css files using the @import method. So, for example, if your html page links to "master.css" which pulls in "reset.css" via @import, then reset.css will not be cached by IE.

It says “Android library projects cannot be launched” because Android library projects cannot be launched. That simple. You cannot run a library. If you want to test a library, create an Android project that uses the library, and execute it.

Bit old question now, but if somebody is looking for solution this works for me.

using Excel = Microsoft.Office.Interop.Excel;

Excel.ApplicationClass excel = new Excel.ApplicationClass();
Excel.Application app = excel.Application;
Excel.Range all = app.get_Range("A1:H10", Type.Missing);

yourElement.setAttribute("style", "background-color:red; font-size:2em;");

Or you could write the element as pure HTML and use .innerHTML = [raw html code]... that's very ugly though.

In answer to your first question, first you use var myElement = createElement(...);, then you do document.body.appendChild(myElement);.

Don't change any environment variables

It was the installer which caused the issue and did not install all the required file.

I just repaired the NODEJS setup on windows 7 and it works very well. May be you can reinstall, just incase something does not work.

myList = [1, 2, 3, 100, 5]    
sorted(range(len(myList)),key=myList.__getitem__)

[0, 1, 2, 4, 3]

I can't extract hours, with HOUR(Date())

There is a way to call HOUR (I would not recommend to use it though because there is DATEPART function) using ODBC Scalar Functions:

SELECT {fn HOUR(GETDATE())} AS hour

LiveDemo

You can't reference an alias except in ORDER BY because SELECT is the second last clause that's evaluated. Two workarounds:

SELECT BalanceDue FROM (
  SELECT (InvoiceTotal - PaymentTotal - CreditTotal) AS BalanceDue
  FROM Invoices
) AS x
WHERE BalanceDue > 0;

Or just repeat the expression:

SELECT (InvoiceTotal - PaymentTotal - CreditTotal) AS BalanceDue
FROM Invoices
WHERE  (InvoiceTotal - PaymentTotal - CreditTotal)  > 0;

I prefer the latter. If the expression is extremely complex (or costly to calculate) you should probably consider a computed column (and perhaps persisted) instead, especially if a lot of queries refer to this same expression.

PS your fears seem unfounded. In this simple example at least, SQL Server is smart enough to only perform the calculation once, even though you've referenced it twice. Go ahead and compare the plans; you'll see they're identical. If you have a more complex case where you see the expression evaluated multiple times, please post the more complex query and the plans.

Here are 5 example queries that all yield the exact same execution plan:

SELECT LEN(name) + column_id AS x
FROM sys.all_columns
WHERE LEN(name) + column_id > 30;

SELECT x FROM (
SELECT LEN(name) + column_id AS x
FROM sys.all_columns
) AS x
WHERE x > 30;

SELECT LEN(name) + column_id AS x
FROM sys.all_columns
WHERE column_id + LEN(name) > 30;

SELECT name, column_id, x FROM (
SELECT name, column_id, LEN(name) + column_id AS x
FROM sys.all_columns
) AS x
WHERE x > 30;

SELECT name, column_id, x FROM (
SELECT name, column_id, LEN(name) + column_id AS x
FROM sys.all_columns
) AS x
WHERE LEN(name) + column_id > 30;

Resulting plan for all five queries:

you can use enumerate keeping the ind/index of the elements is in vm, if you make vm a set you will also have 0(1) lookups:

vm = {-1, -1, -1, -1}

print([ind if q in vm else 9999 for ind,ele in enumerate(vm) ])

Adding on to @Alexandre Aimbiré's answer - sometimes you may need to specify z-index:1 to have the element always on top while scrolling. Like this:

position: -webkit-sticky; /* Safari & IE */
position: sticky;
top: 0;
z-index: 1;

That's not how to add an item to a string. This:

newinv=inventory+str(add)

Means you're trying to concatenate a list and a string. To add an item to a list, use the list.append() method.

inventory.append(add) #adds a new item to inventory
print(inventory) #prints the new inventory

Hope this helps!

You can resolve the issue by looking if your network has any proxies, that is prohibiting the download process. My company's network had a firewall enabled, which was causing the issue for me. So I had to switch to an un-secure network (probably a hotspot from your mobile network), and that worked for me.

Yes, it is because you are using auto layout. Setting the view frame and resizing mask will not work.

You should read Working with Auto Layout Programmatically and Visual Format Language.

You will need to get the current constraints, add the text field, adjust the contraints for the text field, then add the correct constraints on the text field.

You can use jQuery's css function to test the CSS properties, eg. if ($('node').css('display') == 'block').

Colin is right, that there is no explicit event that gets fired when a specific CSS property gets changed. But you may be able to flip it around, and trigger an event that sets the display, and whatever else.

Also consider using adding CSS classes to get the behavior you want. Often you can add a class to a containing element, and use CSS to affect all elements. I often slap a class onto the body element to indicate that an AJAX response is pending. Then I can use CSS selectors to get the display I want.

Not sure if this is what you're looking for.

String[] command = {"cmd.exe" , "/c", "start" , "cmd.exe" , "/k" , "\" dir && ipconfig 
\"" };
ProcessBuilder probuilder = new ProcessBuilder( command );
probuilder.directory(new File("D:\\Folder1"));
Process process = probuilder.start();

One can also use requests if we would like to access a web page using proxies. Python 3 code:

>>> import requests
>>> url = 'http://www.google.com'
>>> proxy = '169.50.87.252:80'
>>> requests.get(url, proxies={"http":proxy})
<Response [200]>

More than one proxies can also be added.

>>> proxy1 = '169.50.87.252:80'
>>> proxy2 = '89.34.97.132:8080'
>>> requests.get(url, proxies={"http":proxy1,"http":proxy2})
<Response [200]>

Please store your JSON file with the .js extension and make sure that your JSON should be in same directory.

The compiler doesn't get the intricate logic where you return in the last iteration of the loop, so it thinks that you could exit out of the loop and end up not returning anything at all.

Instead of returning in the last iteration, just return true after the loop:

public static bool isTwenty(int num) {
  for(int j = 1; j <= 20; j++) {
    if(num % j != 0) {
      return false;
    }
  }
  return true;
}

Side note, there is a logical error in the original code. You are checking if num == 20 in the last condition, but you should have checked if j == 20. Also checking if num % j == 0 was superflous, as that is always true when you get there.

Depending on your regex variant, you might be able to do simply this:

([\w-]+)

Also, you probably don't need the parentheses unless this is part of a larger expression.

For those who stumble upon this from a search (Google) and are trying to translate to .NET and MVC code. (as in my case)

@using (Html.BeginForm("RemoveLostRolls", "Process", FormMethod.Get)) {
     <input type="submit" value="Process" />
}

This will show a button labeled "Process" and take you to "/Process/RemoveLostRolls". Without "FormMethod.Get" it worked, but was seen as a "post".

One option for the follow on question (how to find a customer who might have any number of first names):

List<string> names = new List<string>{ "John", "Max", "Pete" };
bool has = customers.Any(cus => names.Contains(cus.FirstName));

or to retrieve the customer from csv of similar list

string input = "John,Max,Pete";
List<string> names = input.Split(',').ToList();
customer = customers.FirstOrDefault(cus => names.Contains(cus.FirstName));

2019 Answer Late, but hope it helps somebody

This will make sure you won't get null on an empty textfield

• Textfield value is always 0
• When backspacing, you will end with 0
• When value is 0 and you start typing, 0 will be replaced with the actual number

// This will make sure that value never is null when textfield is empty

const minimum = 0;   

export default (props) => {
    const [count, changeCount] = useState(minimum);

    function validate(count) {
        return parseInt(count) | minimum
    }

    function handleChangeCount(count) {
        changeCount(validate(count))
    }

    return (
        <Form>
            <FormGroup>
                <TextInput
                    type="text"
                    value={validate(count)}
                    onChange={handleChangeCount}
                />
            </FormGroup>
            <ActionGroup>
                <Button type="submit">submit form</Button>
            </ActionGroup>
        </Form>
    );
};

I think you can use methods of the str type to do this. There's no need for regular expressions:

def remove_prefix(text, prefix):
    if text.startswith(prefix): # only modify the text if it starts with the prefix
         text = text.replace(prefix, "", 1) # remove one instance of prefix
    return text

In addition to the provided answer, there are more details to navigate. From the function's comments:

/**
 * Navigate based on the provided array of commands and a starting point.
 * If no starting route is provided, the navigation is absolute.
 *
 * Returns a promise that:
 * - resolves to 'true' when navigation succeeds,
 * - resolves to 'false' when navigation fails,
 * - is rejected when an error happens.
 *
 * ### Usage
 *
 * ```
 * router.navigate(['team', 33, 'user', 11], {relativeTo: route});
 *
 * // Navigate without updating the URL
 * router.navigate(['team', 33, 'user', 11], {relativeTo: route, skipLocationChange: true});
 * ```
 *
 * In opposite to `navigateByUrl`, `navigate` always takes a delta that is applied to the current
 * URL.
 */

The Router Guide has more details on programmatic navigation.

Append .done() to your ajax request.

$.ajax({
  url: "test.html",
  context: document.body
}).done(function() { //use this
  alert("DONE!");
});

See the JQuery Doc for .done()

The difference appears when the special parameters are quoted. Let me illustrate the differences:

$ set -- "arg  1" "arg  2" "arg  3"

$ for word in $*; do echo "$word"; done
arg
1
arg
2
arg
3

$ for word in $@; do echo "$word"; done
arg
1
arg
2
arg
3

$ for word in "$*"; do echo "$word"; done
arg  1 arg  2 arg  3

$ for word in "$@"; do echo "$word"; done
arg  1
arg  2
arg  3

one further example on the importance of quoting: note there are 2 spaces between "arg" and the number, but if I fail to quote $word:

$ for word in "$@"; do echo $word; done
arg 1
arg 2
arg 3

and in bash, "$@" is the "default" list to iterate over:

$ for word; do echo "$word"; done
arg  1
arg  2
arg  3

Comments about previous answers

The universal solution is using the HTML tag <sup>, as suggested in the main answer.
However, the idea behind Markdown is precisely to avoid the use of such tags:
The document should look nice as plain text, not only when rendered.

Another answer proposes using Unicode characters, which makes the document look nice as a plain text document but could reduce compatibility.

Finally, I would like to remember the simplest solution for some documents: the character ^.
Some Markdown implementation (e.g. MacDown in macOS) interprets the caret as an instruction for superscript.

Ex.
Sin^2 + Cos^2 = 1
Clearly, Stack Overflow does not interpret the caret as a superscript instruction. However, the text is comprehensible, and this is what really matters when using Markdown.

Two steps, for example,

package main

import (
    "fmt"
    "strings"
)

func main() {
    s := strings.Split("127.0.0.1:5432", ":")
    ip, port := s[0], s[1]
    fmt.Println(ip, port)
}

Output:

127.0.0.1 5432

One step, for example,

package main

import (
    "fmt"
    "net"
)

func main() {
    host, port, err := net.SplitHostPort("127.0.0.1:5432")
    fmt.Println(host, port, err)
}

Output:

127.0.0.1 5432 <nil>

You're missing the option:

<h1>
  <a href="http://stackoverflow.com">
    <img src="logo.png" alt="Stack Overflow" />
  </a>
</h1>

title in href and img to h1 is very, very important!

I have solved this on ubuntu 16.4 PHP 7.0.27-0+deb9u and nginx

Use this code it works perfectly for odd or even list sizes. Hope it help somebody .

 int listSize = listOfArtist.size();
 int mid = 0;
 if (listSize % 2 == 0) {
    mid = listSize / 2;
    Log.e("Parting", "You entered an even number. mid " + mid
                    + " size is " + listSize);
 } else {
    mid = (listSize + 1) / 2;
    Log.e("Parting", "You entered an odd number. mid " + mid
                    + " size is " + listSize);
 }
 //sublist returns List convert it into arraylist * very important
 leftArray = new ArrayList<ArtistModel>(listOfArtist.subList(0, mid));
 rightArray = new ArrayList<ArtistModel>(listOfArtist.subList(mid,
                listSize));

If you are reading that text from a file or from the network.

You can achieve it by adding HTML tags to your text like mentioned

This text is <i>italic</i> and <b>bold</b>
and <u>underlined</u> <b><i><u>bolditalicunderlined</u></b></i>

and then you can use the HTML class that processes HTML strings into displayable styled text.

// textString is the String after you retrieve it from the file
textView.setText(Html.fromHtml(textString));

You should use Modernizr, it will add a class to the body tag.

    var re  = new RegExp("Trident/.*rv:([0-9]{1,}[\.0-9]{0,})");
    if (re.exec(ua) != null)
      rv = parseFloat( RegExp.$1 );
  }
  return rv;
}

Note that IE11 is still is in preview, and the user agent may change before release.

The User-agent string for IE 11 is currently this one :

Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv 11.0) like Gecko

Which means your can simply test, for versions 11.xx,

var isIE11 = !!navigator.userAgent.match(/Trident.*rv 11\./)

For readability, I'd go with

char * s = malloc(snprintf(NULL, 0, "%s %s", first, second) + 1);
sprintf(s, "%s %s", first, second);

If your platform supports GNU extensions, you could also use asprintf():

char * s = NULL;
asprintf(&s, "%s %s", first, second);

If you're stuck with the MS C Runtime, you have to use _scprintf() to determine the length of the resulting string:

char * s = malloc(_scprintf("%s %s", first, second) + 1);
sprintf(s, "%s %s", first, second);

The following will most likely be the fastest solution:

size_t len1 = strlen(first);
size_t len2 = strlen(second);

char * s = malloc(len1 + len2 + 2);
memcpy(s, first, len1);
s[len1] = ' ';
memcpy(s + len1 + 1, second, len2 + 1); // includes terminating null

You'll need to open the workbook to refer to it.

Sub Setwbk()

    Dim wbk As Workbook

    Set wbk = Workbooks.Open("F:\Quarterly Reports\2012 Reports\New Reports\ _
        Master Benchmark Data Sheet.xlsx")

End Sub

_{* Follow Doug's answer if the workbook is already open. For the sake of making this answer as complete as possible, I'm including my comment on his answer:}

Why do I have to "set" it?

Set is how VBA assigns object variables. Since a Range and a Workbook/Worksheet are objects, you must use Set with these.

Unwrap procedure can be performed to assign results to non-entity(which is Beans/POJO). The procedure is as following.

List<JobDTO> dtoList = entityManager.createNativeQuery(sql)
        .setParameter("userId", userId)
        .unwrap(org.hibernate.Query.class).setResultTransformer(Transformers.aliasToBean(JobDTO.class)).list();

The usage is for JPA-Hibernate implementation.

According to http://caniuse.com/#feat=flexbox:

"IE10 and IE11 default values for flex are 0 0 auto rather than 0 1 auto, as per the draft spec, as of September 2013"

So in plain words, if somewhere in your CSS you have something like this: flex:1 , that is not translated the same way in all browsers. Try changing it to 1 0 0 and I believe you will immediately see that it -kinda- works.

The problem is that this solution will probably mess up firefox, but then you can use some hacks to target only Mozilla and change it back:

@-moz-document url-prefix() {
 #flexible-content{
      flex: 1;
    }
}

Since flexbox is a W3C Candidate and not official, browsers tend to give different results, but I guess that will change in the immediate future.

If someone has a better answer I would like to know!

I guess I'm unclear about what the OP was really asking for... Do you want to pass the whole array/list and operate on it inside the function? Or do you want the same thing done on every value/item in the array/list. If the latter is what you wish I have found a method which works well.

I'm more familiar with programming languages such as Fortran and C, in which you can define elemental functions which operate on each element inside an array. I finally tracked down the python equivalent to this and thought I would repost the solution here. The key is to 'vectorize' the function. Here is an example:

def myfunc(a,b):
    if (a>b): return a
    else: return b
vecfunc = np.vectorize(myfunc)
result=vecfunc([[1,2,3],[5,6,9]],[7,4,5])
print(result)

Output:

[[7 4 5]
 [7 6 9]]

If you don't need two-way data-binding:

<select (change)="onChange($event.target.value)">
    <option *ngFor="let i of devices">{{i}}</option>
</select>

onChange(deviceValue) {
    console.log(deviceValue);
}

For two-way data-binding, separate the event and property bindings:

<select [ngModel]="selectedDevice" (ngModelChange)="onChange($event)" name="sel2">
    <option [value]="i" *ngFor="let i of devices">{{i}}</option>
</select>

export class AppComponent {
  devices = 'one two three'.split(' ');
  selectedDevice = 'two';
  onChange(newValue) {
    console.log(newValue);
    this.selectedDevice = newValue;
    // ... do other stuff here ...
}

If devices is array of objects, bind to ngValue instead of value:

<select [ngModel]="selectedDeviceObj" (ngModelChange)="onChangeObj($event)" name="sel3">
  <option [ngValue]="i" *ngFor="let i of deviceObjects">{{i.name}}</option>
</select>
{{selectedDeviceObj | json}}

export class AppComponent {
  deviceObjects = [{name: 1}, {name: 2}, {name: 3}];
  selectedDeviceObj = this.deviceObjects[1];
  onChangeObj(newObj) {
    console.log(newObj);
    this.selectedDeviceObj = newObj;
    // ... do other stuff here ...
  }
}

Plunker - does not use <form>

To get the first day of the month, simply get a Date and set the current day to day 1 of the month. Clear hour, minute, second and milliseconds if you need it.

private static Date firstDayOfMonth(Date date) {
   Calendar calendar = Calendar.getInstance();
   calendar.setTime(date);
   calendar.set(Calendar.DATE, 1);
   return calendar.getTime();
}

First day of the week is the same thing, but using Calendar.DAY_OF_WEEK instead

private static Date firstDayOfWeek(Date date) {
   Calendar calendar = Calendar.getInstance();
   calendar.setTime(date);
   calendar.set(Calendar.DAY_OF_WEEK, 1);
   return calendar.getTime();
}

You must to add a needle headers:

Sample code :

$headers = "From: [email protected]\r\n";
$headers .= "Reply-To: [email protected]\r\n";
$headers .= "Return-Path: [email protected]\r\n";
$headers .= "CC: [email protected]\r\n";
$headers .= "BCC: [email protected]\r\n";

if ( mail($to,$subject,$message,$headers) ) {
   echo "The email has been sent!";
   } else {
   echo "The email has failed!";
   }

Use following interface to communicate between activity and fragment

public interface BundleListener {
    void update(Bundle bundle);
    Bundle getBundle();
}

Or use following this generic listener for two way communication using interface

 /**
 * Created by Qamar4P on 10/11/2017.
 */
public interface GenericConnector<T,E> {
    T getData();
    void updateData(E data);
    void connect(GenericConnector<T,E> connector);
}

fragment show method

public static void show(AppCompatActivity activity) {
        CustomValueDialogFragment dialog = new CustomValueDialogFragment();
        dialog.connector = (GenericConnector) activity;
        dialog.show(activity.getSupportFragmentManager(),"CustomValueDialogFragment");
    }

you can cast your context to GenericConnector in onAttach(Context) too

in your activity

CustomValueDialogFragment.show(this);

in your fragment

...
@Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        connector.connect(new GenericConnector() {
            @Override
            public Object getData() {
                return null;
            }

            @Override
            public void updateData(Object data) {

            }

            @Override
            public void connect(GenericConnector connector) {

            }
        });
    }
...
    public static void show(AppCompatActivity activity, GenericConnector connector) {
            CustomValueDialogFragment dialog = new CustomValueDialogFragment();
            dialog.connector = connector;
            dialog.show(activity.getSupportFragmentManager(),"CustomValueDialogFragment");
        }

Note: Never use it like "".toString().toString().toString(); way.

Time. .Now includes the 09:23:12 or whatever; .Today is the date-part only (at 00:00:00 on that day).

So use .Now if you want to include the time, and .Today if you just want the date!

.Today is essentially the same as .Now.Date

This is really a tricky thing to have a sticky header on your table. I had same requirement but with asp:GridView and then I found it really thought to have sticky header on gridview. There are many solutions available and it took me 3 days trying all the solution but none of them could satisfy.

The main issue that I faced with most of these solutions was the alignment problem. When you try to make the header floating, somehow the alignment of header cells and body cells get off track.

With some solutions, I also got issue of getting header overlapped to first few rows of body, which cause body rows getting hidden behind the floating header.

So now I had to implement my own logic to achieve this, though I also not consider this as perfect solution but this could also be helpful for someone,

Below is the sample table.

<div class="table-holder">
        <table id="MyTable" cellpadding="4" cellspacing="0" border="1px" class="customerTable">
            <thead>
                <tr><th>ID</th><th>First Name</th><th>Last Name</th><th>DOB</th><th>Place</th></tr>
            </thead>
            <tbody>
                <tr><td>1</td><td>Customer1</td><td>LastName</td><td>1-1-1</td><td>SUN</td></tr>
                <tr><td>2</td><td>Customer2</td><td>LastName</td><td>2-2-2</td><td>Earth</td></tr>
                <tr><td>3</td><td>Customer3</td><td>LastName</td><td>3-3-3</td><td>Mars</td></tr>
                <tr><td>4</td><td>Customer4</td><td>LastName</td><td>4-4-4</td><td>Venus</td></tr>
                <tr><td>5</td><td>Customer5</td><td>LastName</td><td>5-5-5</td><td>Saturn</td></tr>
                <tr><td>6</td><td>Customer6</td><td>LastName</td><td>6-6-6</td><td>Jupitor</td></tr>
                <tr><td>7</td><td>Customer7</td><td>LastName</td><td>7-7-7</td><td>Mercury</td></tr>
                <tr><td>8</td><td>Customer8</td><td>LastName</td><td>8-8-8</td><td>Moon</td></tr>
                <tr><td>9</td><td>Customer9</td><td>LastName</td><td>9-9-9</td><td>Uranus</td></tr>
                <tr><td>10</td><td>Customer10</td><td>LastName</td><td>10-10-10</td><td>Neptune</td></tr>
            </tbody>
        </table>
    </div>

Note: The table is wrapped into a DIV with class attribute equal to 'table-holder'.

Below is the JQuery script that I added in my html page header.

<script src="../Scripts/jquery-1.7.2.min.js" type="text/javascript"></script>
<script src="../Scripts/jquery-ui.min.js" type="text/javascript"></script>
<script type="text/javascript">
    $(document).ready(function () {
        //create var for table holder
        var originalTableHolder = $(".table-holder");
        // set the table holder's with
        originalTableHolder.width($('table', originalTableHolder).width() + 17);
        // Create a clone of table holder DIV
        var clonedtableHolder = originalTableHolder.clone();

        // Calculate height of all header rows.
        var headerHeight = 0;
        $('thead', originalTableHolder).each(function (index, element) {
            headerHeight = headerHeight + $(element).height();
        });

        // Set the position of cloned table so that cloned table overlapped the original
        clonedtableHolder.css('position', 'relative');
        clonedtableHolder.css('top', headerHeight + 'px');

        // Set the height of cloned header equal to header height only so that body is not visible of cloned header
        clonedtableHolder.height(headerHeight);
        clonedtableHolder.css('overflow', 'hidden');

        // reset the ID attribute of each element in cloned table
        $('*', clonedtableHolder).each(function (index, element) {
            if ($(element).attr('id')) {
                $(element).attr('id', $(element).attr('id') + '_Cloned');
            }
        });

        originalTableHolder.css('border-bottom', '1px solid #aaa');

        // Place the cloned table holder before original one
        originalTableHolder.before(clonedtableHolder);
    });
</script>

and at last below is the CSS class for bit of coloring purpose.

.table-holder
{
    height:200px;
    overflow:auto;
    border-width:0px;    
}

.customerTable thead
{
    background: #4b6c9e;        
    color:White;
}

So the whole idea of this logic is to place the table into a table holder div and create clone of that holder at client side when page loaded. Now hide the body of table inside clone holder and position the remaining header part over to original header.

Same solution also works for asp:gridview, you need to add two more steps to achieve this in gridview,

1. In OnPrerender event of gridview object in your web page, set the table section of header row equal to TableHeader.

   if (this.HeaderRow != null)
   {
       this.HeaderRow.TableSection = TableRowSection.TableHeader;
   }
   

2. And wrap your grid into <div class="table-holder"></div>.

Note: if your header has clickable controls then you may need to add some more jQuery script to pass the events raised in cloned header to original header. This code is already available in jQuery sticky-header plugin create by jmosbech

In Ecmascript 6,

var obj = {"1":5,"2":7,"3":0,"4":0,"5":0,"6":0,"7":0,"8":0,"9":0,"10":0,"11":0,"12":0};

var res = Object.entries(obj);

console.log(res);

Yes, C++ supports bool and it is a data type. For reference - Bool data type

I had compatibility issues with several plugins I tried, this seems to me to be the simplest way of supporting placeholders on text inputs:

function placeholders(){
    //On Focus
    $(":text").focus(function(){
        //Check to see if the user has modified the input, if not then remove the placeholder text
        if($(this).val() == $(this).attr("placeholder")){
            $(this).val("");
        }
    });

    //On Blur
    $(":text").blur(function(){
        //Check to see if the use has modified the input, if not then populate the placeholder back into the input
        if( $(this).val() == ""){
            $(this).val($(this).attr("placeholder"));
        }
    });
}

For Basic Authentication of WSDL the accepted answers code raises an error. Try the following instead

Authenticator.setDefault(new Authenticator() {
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication("username","password".toCharArray());
    }
});

Almost four years after asking this question, I have finally found an answer that completely satisfies me!

See the details in github:help's guide to Dealing with line endings.

Git allows you to set the line ending properties for a repo directly using the text attribute in the .gitattributes file. This file is committed into the repo and overrides the core.autocrlf setting, allowing you to ensure consistent behaviour for all users regardless of their git settings.

And thus

The advantage of this is that your end of line configuration now travels with your repository and you don't need to worry about whether or not collaborators have the proper global settings.

Here's an example of a .gitattributes file

# Auto detect text files and perform LF normalization
*        text=auto

*.cs     text diff=csharp
*.java   text diff=java
*.html   text diff=html
*.css    text
*.js     text
*.sql    text

*.csproj text merge=union
*.sln    text merge=union eol=crlf

*.docx   diff=astextplain
*.DOCX   diff=astextplain

# absolute paths are ok, as are globs
/**/postinst* text eol=lf

# paths that don't start with / are treated relative to the .gitattributes folder
relative/path/*.txt text eol=lf

There is a convenient collection of ready to use .gitattributes files for the most popular programming languages. It's useful to get you started.

Once you've created or adjusted your .gitattributes, you should perform a once-and-for-all line endings re-normalization.

Note that the GitHub Desktop app can suggest and create a .gitattributes file after you open your project's Git repo in the app. To try that, click the gear icon (in the upper right corner) > Repository settings ... > Line endings and attributes. You will be asked to add the recommended .gitattributes and if you agree, the app will also perform a normalization of all the files in your repository.

Finally, the Mind the End of Your Line article provides more background and explains how Git has evolved on the matters at hand. I consider this required reading.

You've probably got users in your team who use EGit or JGit (tools like Eclipse and TeamCity use them) to commit their changes. Then you're out of luck, as @gatinueta explained in this answer's comments:

This setting will not satisfy you completely if you have people working with Egit or JGit in your team, since those tools will just ignore .gitattributes and happily check in CRLF files https://bugs.eclipse.org/bugs/show_bug.cgi?id=342372

One trick might be to have them commit their changes in another client, say SourceTree. Our team back then preferred that tool to Eclipse's EGit for many use cases.

Who said software is easy? :-/

Isn't this a much better solution? DisplayMetrics comes with everything you need and works from API 1.

public void getScreenInfo(){
    DisplayMetrics metrics = new DisplayMetrics();
    getActivity().getWindowManager().getDefaultDisplay().getMetrics(metrics);

    heightPixels = metrics.heightPixels;
    widthPixels = metrics.widthPixels;
    density = metrics.density;
    densityDpi = metrics.densityDpi;
}

You can also get the actual display (including screen decors, such as Status Bar or software navigation bar) using getRealMetrics, but this works on 17+ only.

Am I missing something?

If the server is well configured, eg it has an up and running MTA, you can just use the mail command.

For instance, to send the content of a file, you can do this:

$ cat /path/to/file | mail -s "your subject" [email protected]

man mail for more details.

Incredibly late but inspired by Homan's brilliantly simple answer, allow me to post a more general solution (general in the sense that Homan's solution crashes on arrays of points with less than 3 vertices):

function smooth(ctx, points)
{
    if(points == undefined || points.length == 0)
    {
        return true;
    }
    if(points.length == 1)
    {
        ctx.moveTo(points[0].x, points[0].y);
        ctx.lineTo(points[0].x, points[0].y);
        return true;
    }
    if(points.length == 2)
    {
        ctx.moveTo(points[0].x, points[0].y);
        ctx.lineTo(points[1].x, points[1].y);
        return true;
    }
    ctx.moveTo(points[0].x, points[0].y);
    for (var i = 1; i < points.length - 2; i ++)
    {
        var xc = (points[i].x + points[i + 1].x) / 2;
        var yc = (points[i].y + points[i + 1].y) / 2;
        ctx.quadraticCurveTo(points[i].x, points[i].y, xc, yc);
    }
    ctx.quadraticCurveTo(points[i].x, points[i].y, points[i+1].x, points[i+1].y);
}

You can convert a number to a string with n decimal places using the SPRINTF command:

>> x = 1.23;
>> sprintf('%0.6f', x)

ans =

1.230000

>> x = 1.23456789;
>> sprintf('%0.6f', x)

ans =

1.234568

At the time of this post all major browsers disable CSS transitions if you try to change the display property, but CSS animations still work fine so we can use them as a workaround.

Example Code (you can apply it to your menu accordingly) Demo:

Add the following CSS to your stylesheet:

@-webkit-keyframes fadeIn {
    from { opacity: 0; }
      to { opacity: 1; }
}
@keyframes fadeIn {
    from { opacity: 0; }
      to { opacity: 1; }
}

Then apply the fadeIn animation to the child on parent hover (and of course set display: block):

.parent:hover .child {
    display: block;
    -webkit-animation: fadeIn 1s;
    animation: fadeIn 1s;
}

Update 2019 - Method that also supports fading out:

(Some JavaScript code is required)

Depending on what you want the file to contain:

• touch /path/to/file for an empty file

• somecommand > /path/to/file for a file containing the output of some command.

    eg: grep --help > randomtext.txt
        echo "This is some text" > randomtext.txt
  

• nano /path/to/file or vi /path/to/file (or any other editor emacs,gedit etc)
  It either opens the existing one for editing or creates & opens the empty file to enter, if it doesn't exist

Create the file using cat

$ cat > myfile.txt

Now, just type whatever you want in the file:

Hello World!

CTRL-D to save and exit

There are several possible solutions:

Create an empty file

touch file

>file

echo -n > file

printf '' > file

The echo version will work only if your version of echo supports the -n switch to suppress newlines. This is a non-standard addition. The other examples will all work in a POSIX shell.

Create a file containing a newline and nothing else

echo '' > file

printf '\n' > file

This is a valid "text file" because it ends in a newline.

Write text into a file

"$EDITOR" file

echo 'text' > file

cat > file <<END \
text
END

printf 'text\n' > file

These are equivalent. The $EDITOR command assumes that you have an interactive text editor defined in the EDITOR environment variable and that you interactively enter equivalent text. The cat version presumes a literal newline after the \ and after each other line. Other than that these will all work in a POSIX shell.

Of course there are many other methods of writing and creating files, too.

you didn't use time() function that returns the current time measured in the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT). use like this:

$date = strtotime(time());
$date = strtotime("+7 day", $date);
echo date('M d, Y', $date);

I would go a step further than just saying "use a docstring". Pick a documentation generation tool, such as pydoc or epydoc (I use epydoc in pyparsing), and use the markup syntax recognized by that tool. Run that tool often while you are doing your development, to identify holes in your documentation. In fact, you might even benefit from writing the docstrings for the members of a class before implementing the class.

let myImage = UIImage(named: "myImageName")
myButton.setImage(myImage , forState: UIControlState.Normal)

where myImageName is the name of your image in your asset catalog.

The Docker daemon binds to a Unix socket instead of a TCP port. By default that Unix socket is owned by the user root and other users can only access it using sudo. The Docker daemon always runs as the root user.

sudo groupadd docker
sudo usermod -aG docker $USER

Log out and log back in so that your group membership is re-evaluated.

docker run hello-world

If timezone is not specified in postgresql.conf or as a server command-line option, the server attempts to use the value of the TZ environment variable as the default time zone. If TZ is not defined or is not any of the time zone names known to PostgreSQL, the server attempts to determine the operating system's default time zone by checking the behavior of the C library function localtime(). The default time zone is selected as the closest match among PostgreSQL's known time zones. (These rules are also used to choose the default value of log_timezone, if not specified.) source

This means that if you do not define a timezone, the server attempts to determine the operating system's default time zone by checking the behavior of the C library function localtime().

If timezone is not specified in postgresql.conf or as a server command-line option, the server attempts to use the value of the TZ environment variable as the default time zone.

It seems to have the System's timezone to be set is possible indeed.

Get the OS local time zone from the shell. In psql:

=> \! date +%Z

You can use the Firefox/Chrome developer toolbar:

1. Open Dev Toolbar Ctrl + Shift + I
2. Go to network tab
3. Press the "disable cache" checkbox (Firefox: top right of toolbar; Chrome: top centre of toolbar)

Going back to absolute basics here. The answers on this page and a little googling have brought me to the following resolution to my issue. Steps to restart the apache service with Xampp installed:-

1. Click the start button and type CMD (if on Windows Vista or later and Apache is installed as a service make sure this is an elevated command prompt)
2. In the command window that appears type cd C:\xampp\apache\bin (the default installation path for Xampp)
3. Then type httpd -k restart

I hope that this is of use to others just starting out with running a local Apache server.

Solved.

I used the JSON.simple library from here https://code.google.com/p/json-simple/ to read the JSON string to keep the order of keys and use JavaCSV library from here http://sourceforge.net/projects/javacsv/ to convert to CSV format.

You can use JsonBuilder for that.

Example Code:

import groovy.json.JsonBuilder

class Person {
    String name
    String address
}

def o = new Person( name: 'John Doe', address: 'Texas' )

println new JsonBuilder( o ).toPrettyString()

In case any one wants it in Kotlin :

val dialogBuilder = AlertDialog.Builder(this)
// ...Irrelevant code for customizing the buttons and title
val dialogView = layoutInflater.inflate(R.layout.alert_label_editor, null)
dialogBuilder.setView(dialogView)

val editText =  dialogView.findViewById(R.id.label_field)
editText.setText("test label")
val alertDialog = dialogBuilder.create()
alertDialog.show()

I set the delegate of the UITextField to my ViewController class.

In that class I implemented this method as following:

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    [textField resignFirstResponder];
    return NO;
}

Use ack. Checkout its --passthru option here: ack. It has the added benefit of allowing full perl regular expressions.

$ ack --passthru 'pattern1' file_name

$ command_here | ack --passthru 'pattern1'

You can also do it using grep like this:

$ grep --color -E '^|pattern1|pattern2' file_name

$ command_here | grep --color -E '^|pattern1|pattern2'

This will match all lines and highlight the patterns. The ^ matches every start of line, but won't get printed/highlighted since it's not a character.

(Note that most of the setups will use --color by default. You may not need that flag).

Try using this instead:

var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();

It's bit hard to navigate Google's api but here is the relevant documentation.

One thing I had trouble finding was how to go in the other direction. From coordinates to an address. Here is the code I neded upp using. Please not that I also use jquery.

$.each(results[0].address_components, function(){
    $("#CreateDialog").find('input[name="'+ this.types+'"]').attr('value', this.long_name);
});

What I'm doing is to loop through all the returned address_components and test if their types match any input element names I have in a form. And if they do I set the value of the element to the address_components value.
If you're only interrested in the whole formated address then you can follow Google's example

The ways in which you can get the results are:

• if your_dict.has_key(key) Removed in Python 3
• if key in your_dict
• try/except block

Which is better is dependent on 3 things:

1. Does the dictionary 'normally has the key' or 'normally does not have the key'.
2. Do you intend to use conditions like if...else...elseif...else?
3. How big is dictionary?

Read More: http://paltman.com/try-except-performance-in-python-a-simple-test/

Use of try/block instead of 'in' or 'if':

try:
    my_dict_of_items[key_i_want_to_check]
except KeyError:
    # Do the operation you wanted to do for "key not present in dict".
else:
    # Do the operation you wanted to do with "key present in dict."

It's very simple to do this recursively. The basic idea is that for each element, the set of subsets can be divided equally into those that contain that element and those that don't, and those two sets are otherwise equal.

• For n=1, the set of subsets is {{}, {1}}
• For n>1, find the set of subsets of 1,...,n-1 and make two copies of it. For one of them, add n to each subset. Then take the union of the two copies.

Edit To make it crystal clear:

• The set of subsets of {1} is {{}, {1}}
• For {1, 2}, take {{}, {1}}, add 2 to each subset to get {{2}, {1, 2}} and take the union with {{}, {1}} to get {{}, {1}, {2}, {1, 2}}
• Repeat till you reach n

Here is a very easy way of doing that

 $(function () {
    $(".glyphicon").unbind('click');
    $(".glyphicon").click(function (e) {
        $(this).toggleClass("glyphicon glyphicon-chevron-up glyphicon glyphicon-chevron-down");
});

Hope this helps :D

val testDataFrame = Seq(
  (1.0, 4.0), (2.0, 5.0), (3.0, 6.0)
).toDF("A", "B")

val (maxA, maxB) = testDataFrame.select(max("A"), max("B"))
  .as[(Double, Double)]
  .first()
println(maxA, maxB)

And the result is (3.0,6.0), which is the same to the testDataFrame.agg(max($"A"), max($"B")).collect()(0).However, testDataFrame.agg(max($"A"), max($"B")).collect()(0) returns a List, [3.0,6.0]

when you save the #ID as the cookie to recognize logged in users, you actually are showing data to users that is not related to them. In addition, if a third party tries to set random IDs as cookie data in their browser, they will be able to convince the server that they are a user while they actually are not. That's a lack of security.

You have used cookies, and as you said you have already completed most of the project. besides cookie has the privilege of remaining for a long time, while sessions end more quickly. So sessions are not suitable in this case. In reality many famous and popular websites and services use cookie and you can stay logged-in for a long time. But how can you use their method to create a safer log-in process?

here's the idea: you can help the way you use cookies: If you use random keys instead of IDs to recognize logged-in users, first, you don't leak your primary data to random users, and second, If you consider the Random key large enough, It will be harder for anyone to guess a key or create a random one. for example you can save a 40 length key like this in User's browser: "KUYTYRFU7987gJHFJ543JHBJHCF5645UYTUYJH54657jguthfn" and it will be less likely for anyone to create the exact key and pretend to be someone else.

Scala:

Leaddetails.join(
    Utm_Master, 
    Leaddetails("LeadSource") <=> Utm_Master("LeadSource")
        && Leaddetails("Utm_Source") <=> Utm_Master("Utm_Source")
        && Leaddetails("Utm_Medium") <=> Utm_Master("Utm_Medium")
        && Leaddetails("Utm_Campaign") <=> Utm_Master("Utm_Campaign"),
    "left"
)

To make it case insensitive,

import org.apache.spark.sql.functions.{lower, upper}

then just use lower(value) in the condition of the join method.

Eg: dataFrame.filter(lower(dataFrame.col("vendor")).equalTo("fortinet"))

On UNIX Just use this:

mkdir -p $(OBJDIR)

The -p option to mkdir prevents the error message if the directory exists.

I was able to do that with :

var dateTest = new Date("04/04/2013");
dateTest.toLocaleString().substring(0,dateTest.toLocaleString().indexOf(' '))

the 04/04/2013 is just for testing, replace with your Date Object.

I wasted a lot of time on this. Turns out that the default database library is not supported for Python 3. You have to use a different one.

A solution using modern-async's map():

import { map } from 'modern-async'

...
const result = await map(myArray, async (v) => {
    ...
})

The advantage of using that library is that you can control the concurrency using mapLimit() or mapSeries().

Just for convenience, very simple.

        retval += ( '0123456789ABCDEF'[int(intval % 16)])
        retval += delim
    return( retval[:-1])

# Out[439]: '48:65:6C:6C:6F:20:57:6F:72:6C:64:21'

It looks like the best approach is to use:

ContextCompat.getColor(context, R.color.color_name)

eg:

yourView.setBackgroundColor(ContextCompat.getColor(applicationContext,
                            R.color.colorAccent))

This will choose the Marshmallow two parameter method or the pre-Marshmallow method appropriately.

All the plugins listed above have a serious problem - they are using the virtual folders implemented via WordPress Taxonomy API, while X4 Media Library is using the real physical folders located in your wp-content/uploads directory on the server.

What happens when you put some images to the folder using any plugin listed above? Because of they are using the virtual folders, the destinition folder is represented as a taxonomy tag in the database, so they just assign the folder's tag to moved files.

There are no real modifications happened on your physical disk, in the wp-content/uploads directory. You can see that images URL didn't change when you move them to another folder.

Alternatively, with X4 Media Library if you put some files to the folder they will really be moved to that physical folder on your disk, in the wp-content/uploads directory, and the images URL will be changed automatically.

Moreover, this plugin will make sure that all the links associated with these images in all your Posts, Pages and other custom types will be updated automatically.

${word:$(expr index "$word" "="):1}

Full reference present at : listview with checkbox android studio Pass selected items to next activity

Main source code is as below.

Create a model class first

public class Model {

    private boolean isSelected;
    private String animal;

    public String getAnimal() {
        return animal;
    }

    public void setAnimal(String animal) {
        this.animal = animal;
    }

    public boolean getSelected() {
        return isSelected;
    }

    public void setSelected(boolean selected) {
        isSelected = selected;
    }
}

Then in adapter class, setTags to checkbox. Use those tags in onclicklistener of checkbox.

A tuple is immutable and thus you get the error you posted.

>>> pixels = [1, 2, 3]
>>> pixels[0] = 5
>>> pixels = (1, 2, 3)
>>> pixels[0] = 5
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'tuple' object does not support item assignment

In your specific case, as correctly pointed out in other answers, you should write:

pixel = (pixel[0] + 20, pixel[1], pixel[2])

To allow Windows installers to find the installed Python directory in Windows 7, OR, change which Python installation to install an installer into, add the installed path into the InstallPath registry key's (Default) value:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python\PythonCore\2.X\InstallPath

Where "X" is the Python version (that is, 2.5, 2.6, or 2.7).

For .net 2.0 this works. It DOES compile both in the same project if you create sub directories of in app code with the related language code. As of yet, I am looking for whether this should work in 3.5 or not though.

It looks like it is 100% a pytest code pattern.

See:

pytest fixtures: explicit, modular, scalable

I had the same problem with it, and this is why I found this post ;)

# ./tests/test_twitter1.py
import os
import pytest

from mylib import db
# ...

@pytest.fixture
def twitter():
    twitter_ = db.Twitter()
    twitter_._debug = True
    return twitter_

@pytest.mark.parametrize("query,expected", [
    ("BANCO PROVINCIAL", 8),
    ("name", 6),
    ("castlabs", 42),
])
def test_search(twitter: db.Twitter, query: str, expected: int):

    for query in queries:
        res = twitter.search(query)
        print(res)
        assert res

And it will warn with This inspection detects shadowing names defined in outer scopes.

To fix that, just move your twitter fixture into ./tests/conftest.py

# ./tests/conftest.py
import pytest

from syntropy import db


@pytest.fixture
def twitter():
    twitter_ = db.Twitter()
    twitter_._debug = True
    return twitter_

And remove the twitter fixture, like in ./tests/test_twitter2.py:

# ./tests/test_twitter2.py
import os
import pytest

from mylib import db
# ...

@pytest.mark.parametrize("query,expected", [
    ("BANCO PROVINCIAL", 8),
    ("name", 6),
    ("castlabs", 42),
])
def test_search(twitter: db.Twitter, query: str, expected: int):

    for query in queries:
        res = twitter.search(query)
        print(res)
        assert res

This will be make happy for QA, PyCharm and everyone.

Depending on your exact requirements, you may do best with a jagged array of sorts with:

List<string>[] results = new { new List<string>(), new List<string>() };

Or you may do well with a list of lists or some other such construct.

int myInt = myBoolean ? 1 : 0;

^^

PS : true = 1 and false = 0

It denotes an rvalue reference. Rvalue references will only bind to temporary objects, unless explicitly generated otherwise. They are used to make objects much more efficient under certain circumstances, and to provide a facility known as perfect forwarding, which greatly simplifies template code.

In C++03, you can't distinguish between a copy of a non-mutable lvalue and an rvalue.

std::string s;
std::string another(s);           // calls std::string(const std::string&);
std::string more(std::string(s)); // calls std::string(const std::string&);

In C++0x, this is not the case.

std::string s;
std::string another(s);           // calls std::string(const std::string&);
std::string more(std::string(s)); // calls std::string(std::string&&);

Consider the implementation behind these constructors. In the first case, the string has to perform a copy to retain value semantics, which involves a new heap allocation. However, in the second case, we know in advance that the object which was passed in to our constructor is immediately due for destruction, and it doesn't have to remain untouched. We can effectively just swap the internal pointers and not perform any copying at all in this scenario, which is substantially more efficient. Move semantics benefit any class which has expensive or prohibited copying of internally referenced resources. Consider the case of std::unique_ptr- now that our class can distinguish between temporaries and non-temporaries, we can make the move semantics work correctly so that the unique_ptr cannot be copied but can be moved, which means that std::unique_ptr can be legally stored in Standard containers, sorted, etc, whereas C++03's std::auto_ptr cannot.

Now we consider the other use of rvalue references- perfect forwarding. Consider the question of binding a reference to a reference.

std::string s;
std::string& ref = s;
(std::string&)& anotherref = ref; // usually expressed via template

Can't recall what C++03 says about this, but in C++0x, the resultant type when dealing with rvalue references is critical. An rvalue reference to a type T, where T is a reference type, becomes a reference of type T.

(std::string&)&& ref // ref is std::string&
(const std::string&)&& ref // ref is const std::string&
(std::string&&)&& ref // ref is std::string&&
(const std::string&&)&& ref // ref is const std::string&&

Consider the simplest template function- min and max. In C++03 you have to overload for all four combinations of const and non-const manually. In C++0x it's just one overload. Combined with variadic templates, this enables perfect forwarding.

template<typename A, typename B> auto min(A&& aref, B&& bref) {
    // for example, if you pass a const std::string& as first argument,
    // then A becomes const std::string& and by extension, aref becomes
    // const std::string&, completely maintaining it's type information.
    if (std::forward<A>(aref) < std::forward<B>(bref))
        return std::forward<A>(aref);
    else
        return std::forward<B>(bref);
}

I left off the return type deduction, because I can't recall how it's done offhand, but that min can accept any combination of lvalues, rvalues, const lvalues.

secure - This attribute tells the browser to only send the cookie if the request is being sent over a secure channel such as HTTPS. This will help protect the cookie from being passed over unencrypted requests. If the application can be accessed over both HTTP and HTTPS, then there is the potential that the cookie can be sent in clear text.

You don't need to have a reportViewer control anywhere - you can create the LocalReport on the fly:

var lr = new LocalReport
{
    ReportPath = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) ?? @"C:\", "Reports", "PathOfMyReport.rdlc"),
    EnableExternalImages = true

lr.DataSources.Add(new ReportDataSource("NameOfMyDataSet", model));

string mimeType, encoding, extension;

Warning[] warnings;
string[] streams;
var renderedBytes = lr.Render
    (
        "PDF",
        @"<DeviceInfo><OutputFormat>PDF</OutputFormat><HumanReadablePDF>False</HumanReadablePDF></DeviceInfo>",
        out mimeType,
        out encoding,
        out extension,
        out streams,
        out warnings
    );

var saveAs = string.Format("{0}.pdf", Path.Combine(tempPath, "myfilename"));

var idx = 0;
while (File.Exists(saveAs))
{
    idx++;
    saveAs = string.Format("{0}.{1}.pdf", Path.Combine(tempPath, "myfilename"), idx);
}

using (var stream = new FileStream(saveAs, FileMode.Create, FileAccess.Write))
{
    stream.Write(renderedBytes, 0, renderedBytes.Length);
    stream.Close();
}

lr.Dispose();

You can also add parameters: (lr.SetParameter()), handle subreports: (lr.SubreportProcessing+=YourHandler), or pretty much anything you can think of.

The public keyword is used only when declaring a class method.

Since you're declaring a simple function and not a class you need to remove public from your code.

You can create a common volume for all Postgres data

 docker volume create pgdata

or you can set it to the compose file

   version: "3"
   services:
     db:
       image: postgres
       environment:
         - POSTGRES_USER=postgres
         - POSTGRES_PASSWORD=postgress
         - POSTGRES_DB=postgres
       ports:
         - "5433:5432"
       volumes:
         - pgdata:/var/lib/postgresql/data
       networks:
         - suruse
   volumes: 
     pgdata:

It will create volume name pgdata and mount this volume to container's path.

You can inspect this volume

docker volume inspect pgdata

// output will be

AnyObject is the official way to use a weak reference in Swift.

class MyClass {
    weak var delegate: MyClassDelegate?
}

protocol MyClassDelegate: AnyObject {
}

From Apple:

To prevent strong reference cycles, delegates should be declared as weak references. For more information about weak references, see Strong Reference Cycles Between Class Instances. Marking the protocol as class-only will later allow you to declare that the delegate must use a weak reference. You mark a protocol as being class-only by inheriting from AnyObject, as discussed in Class-Only Protocols.

Well, you essentially create a JDialog, add your text components and make it visible. It might help if you narrow down which specific bit you're having trouble with.

When you use a code like this:

using (var rsa = new RSACryptoServiceProvider(1024))
{
   // Do something with the key...
   // Encrypt, export, etc.
}

.NET (actually Windows) stores your key in a persistent key container forever. The container is randomly generated by .NET

This means:

1. Any random RSA/DSA key you have EVER generated for the purpose of protecting data, creating custom X.509 certificate, etc. may have been exposed without your awareness in the Windows file system. Accessible by anyone who has access to your account.

2. Your disk is being slowly filled with data. Normally not a big concern but it depends on your application (e.g. it might generates hundreds of keys every minute).

To resolve these issues:

using (var rsa = new RSACryptoServiceProvider(1024))
{
   try
   {
      // Do something with the key...
      // Encrypt, export, etc.
   }
   finally
   {
      rsa.PersistKeyInCsp = false;
   }
}

ALWAYS

Android does not support MySQL out of the box. The "normal" way to access your database would be to put a Restful server in front of it and use the HTTPS protocol to connect to the Restful front end.

Have a look at ContentProvider. It is normally used to access a local database (SQLite) but it can be used to get data from any data store.

I do recommend that you look at having a local copy of all/some of your websites data locally, that way your app will still work when the Android device hasn't got a connection. If you go down this route then a service can be used to keep the two databases in sync.

cout << fixed << setprecision(2) << total;

setprecision specifies the minimum precision. So

cout << setprecision (2) << 1.2; 

will print 1.2

fixed says that there will be a fixed number of decimal digits after the decimal point

cout << setprecision (2) << fixed << 1.2;

will print 1.20

Elvis operator:

?: is the Elvis operator. This is a binary operator which does the following:

Coerces the value left of ?: to a boolean and checks if it is true. If true it will return the expression on the left side, if false it will return the expression on the right side.

Example:

var_dump(0 ?: "Expression not true");     // expression returns: Expression not true
var_dump("" ?: "Expression not true");    // expression returns: Expression not true
var_dump("hi" ?: "Expression not true");  // expression returns string hi
var_dump(null ?: "Expression not true");  // expression returns: Expression not true
var_dump(56 ?: "Expression not true");    // expression return int 56

When to use:

The Elvis operator is basically shorthand syntax for a specific case of the ternary operator which is:

$testedVar ? $ testedVar : $otherVar;

The Elvis operator will make the syntax more consise in the following manner:

$testedVar ?: $otherVar;

    <script type="application/javascript">
            function getip(json){
            alert(json.ip); // alerts the ip address
    }
    </script>

    <script type="application/javascript" src="http://jsonip.appspot.com/?callback=getip"></script>

StringExtension class is the way forward, I've combined a couple of the posts above to give a complete code example:

public static class StringExtensions
{
    /// <summary>
    /// Allows case insensitive checks
    /// </summary>
    public static bool Contains(this string source, string toCheck, StringComparison comp)
    {
        return source.IndexOf(toCheck, comp) >= 0;
    }
}

1. You are putting there a two-digits year. The first century. And the Gregorian calendar started in the 16th century. I think you should add 2000 to the year.

2. Month in the function new GregorianCalendar(year, month, days) is 0-based. Subtract 1 from the month there.

3. Change the body of the second function as follows:

       String dateFormatted = null;
       SimpleDateFormat fmt = new SimpleDateFormat("dd-MMM-yyyy");
       try {
           dateFormatted = fmt.format(date);
       }
       catch ( IllegalArgumentException e){
           System.out.println(e.getMessage());
       }
       return dateFormatted;
   

After debugging, you'll see that simply GregorianCalendar can't be an argument of the fmt.format();.

Really, nobody needs GregorianCalendar as output, even you are told to return "a string".

Change the header of your format function to

public static String format(final Date date) 

and make the appropriate changes. fmt.format() will take the Date object gladly.

4. Always after an unexpected exception arises, catch it yourself, don't allow the Java machine to do it. This way, you'll understand the problem.

             <ul>

                <li><a <?php echo ($page == "yourfilename") ? "class='active'" : ""; ?> href="user.php" ><span>Article</span></a></li>
                <li><a <?php echo ($page == "yourfilename") ? "class='active'" : ""; ?> href="newarticle.php"><span>New Articles</span></a></li>

                </ul>

Use Json class instead of Content as shown following:

    //  When I want to return an error:
    if (!isFileSupported)
    {
        Response.StatusCode = (int) HttpStatusCode.BadRequest;
        return Json("The attached file is not supported", MediaTypeNames.Text.Plain);
    }
    else
    {
        //  When I want to return sucess:
        Response.StatusCode = (int)HttpStatusCode.OK; 
        return Json("Message sent!", MediaTypeNames.Text.Plain);
    }

Also set contentType:

contentType: 'application/json; charset=utf-8',

Please use below trick:

• Create an image button with your icon and set its background color to be transparent.
• Put the image button on the EditText
• Implement the 'onclic'k listener of the button to execute your function

If you are looking for a popup in the page, that is not a new browser window, then I would take a look at the various "LightBox" implementations in Javascript.

EDIT: This answer no longer holds true. CSS is well supportedand Javascript (read: JScript) is now pretty much required for any web experience, and few folks disable javascript.

The original answer, as my opinion in 2009.

Off the top of my head:

With CSS, you may have issues with browser support.

With JScript, people can disable jscript (thats what I do).

I believe the preferred method is to do content in HTML, Layout with CSS, and anything dynamic in JScript. So in this instance, you would probably want to take the CSS approach.

Came across the same feature but I had to do the below to make it work.

If you are seeing 'ModuleNotFoundError: No module named', you probably need the dot(.) in front of the filename as below;

from .file import funtion

I'm not sure exactly what you want, but it sounds like it should be possible, and it also sounds like you're already on the right track.

Here are a few links that might help:

jQuery PART:

$(".dropdown-menu").on('click', 'li a', function(){
  var selText = $(this).children("h4").html();


 $(this).parent('li').siblings().removeClass('active');
    $('#vl').val($(this).attr('data-value'));
  $(this).parents('.btn-group').find('.selection').html(selText);
  $(this).parents('li').addClass("active");
});

HTML PART:

<div class="container">
  <div class="btn-group">
    <a class="btn btn-default dropdown-toggle btn-blog " data-toggle="dropdown" href="#" id="dropdownMenu1" style="width:200px;"><span class="selection pull-left">Select an option </span> 
      <span class="pull-right glyphiconglyphicon-chevron-down caret" style="float:right;margin-top:10px;"></span></a>

     <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1">
       <li><a href="#" class="" data-value=1><p> HER Can you write extra text or <b>HTLM</b></p> <h4> <span class="glyphicon glyphicon-plane"></span>  <span> Your Option 1</span> </h4></a>  </li>
       <li><a href="#" class="" data-value=2><p> HER Can you write extra text or <i>HTLM</i> or some long long long long long long long long long long text </p><h4> <span class="glyphicon glyphicon-briefcase"></span> <span>Your Option 2</span>  </h4></a>
      </li>
      <li class="divider"></li>
   <li><a href="#" class="" data-value=3><p> HER Can you write extra text or <b>HTLM</b> or some </p><h4> <span class="glyphicon glyphicon-heart text-danger"></span> <span>Your Option 3</span>  </h4></a>

    </ul>
  </div>
  <input type="text" id="vl" />
</div>  

I came here because I was trying to use ifconfig on the container to find its IPAaddress and there was no ifconfig. If you really need ifconfig on the container go with @vishnu-narayanan answer above, however you may be able to get the information you need by using docker inspect on the host:

docker inspect <containerid>

There is lots of good stuff in the output including IPAddress of container:

"Networks": {
    "bridge": {
        "IPAMConfig": null,
        "Links": null,
        "Aliases": null,
        "NetworkID": "12345FAKEID",
        "EndpointID": "12345FAKEENDPOINTID",
        "Gateway": "172.17.0.1",
        "IPAddress": "172.17.0.3",
        "IPPrefixLen": 16,
        "IPv6Gateway": "",
        "GlobalIPv6Address": "",
        "GlobalIPv6PrefixLen": 0,
        "MacAddress": "01:02:03:04:05:06",
        "DriverOpts": null
    }
}

I will use CXF also you can think of AXIS 2 .

The best way to do it may be using JAX RS Refer this example

Example:

wsimport -p stockquote http://stockquote.xyz/quote?wsdl

This will generate the Java artifacts and compile them by importing the http://stockquote.xyz/quote?wsdl.

I struggled a bit with coming up with a bash function that wraps Peter Tillemans' answer but here's what I came up with:

function regex { perl -n -e "/$1/ && printf \"%s\n\", "'$1' }

I found this worked better than opsb's awk-based bash function for the following regular expression argument, because I do not want the "ms" to be printed.

'([0-9]*)ms$'

Meteor's strength is in it's real-time updates feature which works well for some of the social applications you see nowadays where you see everyone's updates for what you're working on. These updates center around replicating subsets of a MongoDB collection underneath the covers as local mini-mongo (their client side MongoDB subset) database updates on your web browser (which causes multiple render events to be fired on your templates). The latter part about multiple render updates is also the weakness. If you want your UI to control when the UI refreshes (e.g., classic jQuery AJAX pages where you load up the HTML and you control all the AJAX calls and UI updates), you'll be fighting this mechanism.

Meteor uses a nice stack of Node.js plugins (Handlebars.js, Spark.js, Bootstrap css, etc. but using it's own packaging mechanism instead of npm) underneath along w/ MongoDB for the storage layer that you don't have to think about. But sometimes you end up fighting it as well...e.g., if you want to customize the Bootstrap theme, it messes up the loading sequence of Bootstrap's responsive.css file so it no longer is responsive (but this will probably fix itself when Bootstrap 3.0 is released soon).

So like all "full stack frameworks", things work great as long as your app fits what's intended. Once you go beyond that scope and push the edge boundaries, you might end up fighting the framework...

I used the following code to create a temporary file for writing bytes. And its working fine.

File file = new File(Environment.getExternalStorageDirectory() + "/" + File.separator + "test.txt");
file.createNewFile();
byte[] data1={1,1,0,0};
//write the bytes in file
if(file.exists())
{
     OutputStream fo = new FileOutputStream(file);              
     fo.write(data1);
     fo.close();
     System.out.println("file created: "+file);
}               

//deleting the file             
file.delete();
System.out.println("file deleted");

test = {'foo': 'bar', 'hello': 'world'}
ls = []
for key in test.keys():
    ls.append(key)
print(ls[0])

Conventional way of appending the keys to a statically defined list and then indexing it for same

If you need the full url (for instance to send by email) consider using one of the following built-in methods:

With this you create the route to use to build the url:

Url.RouteUrl("OpinionByCompany", new RouteValueDictionary(new{cid=newop.CompanyID,oid=newop.ID}), HttpContext.Request.Url.Scheme, HttpContext.Request.Url.Authority)

Here the url is built after the route engine determine the correct one:

Url.Action("Detail","Opinion",new RouteValueDictionary(new{cid=newop.CompanyID,oid=newop.ID}),HttpContext.Request.Url.Scheme, HttpContext.Request.Url.Authority)

In both methods, the last 2 parameters specifies the protocol and hostname.
