Alternatively if you want to persist in using the DocumentType class. Then you could just add the following annotation on top of your DocumentType class.

    @XmlRootElement(name="document")

Note: the String value "document" refers to the name of the root tag of the xml message.

Thanks to everyone above, but this is now fixed. For the benefit of others the most significant error was in aligning the three namespaces as suggested by Ian.

For completeness, here is the corrected XML and XSD

Here is the XML, with the typos corrected (sorry for any confusion caused by tardiness)

<?xml version="1.0" encoding="UTF-8"?>

<Root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns="urn:Test.Namespace"  
      xsi:schemaLocation="urn:Test.Namespace Test1.xsd">
    <element1 id="001">
        <element2 id="001.1">
            <element3 id="001.1" />
        </element2>
    </element1>
</Root>

and, here is the Schema

<?xml version="1.0"?>

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            targetNamespace="urn:Test.Namespace"
            xmlns="urn:Test.Namespace"
            elementFormDefault="qualified">
    <xsd:element name="Root">
        <xsd:complexType>
            <xsd:sequence>
                <xsd:element name="element1" maxOccurs="unbounded" type="element1Type"/>
            </xsd:sequence>
        </xsd:complexType>
    </xsd:element>
       
    <xsd:complexType name="element1Type">
        <xsd:sequence>
            <xsd:element name="element2" maxOccurs="unbounded" type="element2Type"/>
        </xsd:sequence>
        <xsd:attribute name="id" type="xsd:string"/>
    </xsd:complexType>
       
    <xsd:complexType name="element2Type">
        <xsd:sequence>
            <xsd:element name="element3" type="element3Type"/>
        </xsd:sequence>
        <xsd:attribute name="id" type="xsd:string"/>
    </xsd:complexType>

    <xsd:complexType name="element3Type">
        <xsd:attribute name="id" type="xsd:string"/>
    </xsd:complexType>        
</xsd:schema>

Thanks again to everyone, I hope this is of use to somebody else in the future.

You have a couple of problems here.

First, the XSD has an issue where an element is both named or referenced; in your case should be referenced.

Change:

<xsd:element name="stock" ref="Stock" minOccurs="1" maxOccurs="unbounded"/> 

To:

<xsd:element name="stock" type="Stock" minOccurs="1" maxOccurs="unbounded"/> 

And:

• Remove the declaration of the global element Stock
• Create a complex type declaration for a type named Stock

So:

<xsd:element name="Stock">
    <xsd:complexType>

To:

<xsd:complexType name="Stock">

Make sure you fix the xml closing tags.

The second problem is that the correct way to reference an external XSD is to use XSD schema with import/include within a wsdl:types element. wsdl:import is reserved to referencing other WSDL files. More information is available by going through the WS-I specification, section WSDL and Schema Import. Based on WS-I, your case would be:

INCORRECT: (the way you showed it)

<?xml version="1.0" encoding="UTF-8"?>
<definitions targetNamespace="http://stock.com/schemas/services/stock/wsdl"
    .....xmlns:external="http://stock.com/schemas/services/stock"
    <import namespace="http://stock.com/schemas/services/stock" location="Stock.xsd" />
    <message name="getStockQuoteResp">
        <part name="parameters" element="external:getStockQuoteResponse" />
    </message>
</definitions>

CORRECT:

<?xml version="1.0" encoding="UTF-8"?>
<definitions targetNamespace="http://stock.com/schemas/services/stock/wsdl"
    .....xmlns:external="http://stock.com/schemas/services/stock"
    <types>
        <schema xmlns="http://www.w3.org/2001/XMLSchema">
            <import namespace="http://stock.com/schemas/services/stock" schemaLocation="Stock.xsd" />             
        </schema>
    </types>
    <message name="getStockQuoteResp">
        <part name="parameters" element="external:getStockQuoteResponse" />
    </message>
</definitions>

SOME processors may support both syntaxes. The XSD you put out shows issues, make sure you first validate the XSD.

It would be better if you go the WS-I way when it comes to WSDL authoring.

Other issues may be related to the use of relative vs. absolute URIs in locating external content.

Set the minOccurs attribute to 0 in the schema like so:

<?xml version="1.0"?>
  <xs:schema version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
    <xs:element name="request">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="amenity">
                    <xs:complexType>
                        <xs:sequence>
                            <xs:element name="description" type="xs:string" minOccurs="0" />
                        </xs:sequence>
                    </xs:complexType>
                </xs:element>
            </xs:sequence>
        </xs:complexType>
    </xs:element> </xs:schema>

you need to create a type and make the attribute of that type:

<xs:simpleType name="curr">
  <xs:restriction base="xs:string">
    <xs:enumeration value="pounds" />
    <xs:enumeration value="euros" />
    <xs:enumeration value="dollars" />
  </xs:restriction>
</xs:simpleType>

then:

<xs:complexType>
    <xs:attribute name="currency" type="curr"/>
</xs:complexType>

MSK,

Have you tried setting a namespace declaration to your member variables like this? :

@XmlElement(required = true, namespace = "http://example.com/a")
protected String username;

@XmlElement(required = true, namespace = "http://example.com/a")
protected String password;

For our project, it solved namespace issues. We also had to create NameSpacePrefixMappers.

In the schema you have in your question, child1 or child2 can appear in any order, any number of times. So this sounds like what you are looking for.

Edit: if you wanted only one of them to appear an unlimited number of times, the unbounded would have to go on the elements instead:

Edit: Fixed type in XML.

Edit: Capitalised O in maxOccurs

<xs:element name="foo">
   <xs:complexType>
     <xs:choice maxOccurs="unbounded">
       <xs:element name="child1" type="xs:int" maxOccurs="unbounded"/>
       <xs:element name="child2" type="xs:string" maxOccurs="unbounded"/>
     </xs:choice>
   </xs:complexType>
</xs:element>

I have noticed that XMLSpy(at least 2011 version)needs a targetNameSpace defined if elementFormDefault="qualified" is used. Otherwise won't validate. And also won't generate xmls with namespace prefixes

paxdiablo's answer is great, but there are a lot of common resolutions that have just a few more or less pixels in a given direction, and the greatest common divisor approach gives horrible results to them.

Take for example the well behaved resolution of 1360x765 which gives a nice 16:9 ratio using the gcd approach. According to Steam, this resolution is only used by 0.01% of it's users, while 1366x768 is used by a whoping 18.9%. Let's see what we get using the gcd approach:

1360x765 - 16:9 (0.01%)
1360x768 - 85:48 (2.41%)
1366x768 - 683:384 (18.9%)

We'd want to round up that 683:384 ratio to the closest, 16:9 ratio.

I wrote a python script that parses a text file with pasted numbers from the Steam Hardware survey page, and prints all resolutions and closest known ratios, as well as the prevalence of each ratio (which was my goal when I started this):

# Contents pasted from store.steampowered.com/hwsurvey, section 'Primary Display Resolution'
steam_file = './steam.txt'

# Taken from http://upload.wikimedia.org/wikipedia/commons/thumb/f/f0/Vector_Video_Standards4.svg/750px-Vector_Video_Standards4.svg.png
accepted_ratios = ['5:4', '4:3', '3:2', '8:5', '5:3', '16:9', '17:9']

#-------------------------------------------------------
def gcd(a, b):
    if b == 0: return a
    return gcd (b, a % b)

#-------------------------------------------------------
class ResData:

    #-------------------------------------------------------
    # Expected format: 1024 x 768 4.37% -0.21% (w x h prevalence% change%)
    def __init__(self, steam_line):
        tokens = steam_line.split(' ')
        self.width  = int(tokens[0])
        self.height = int(tokens[2])
        self.prevalence = float(tokens[3].replace('%', ''))

        # This part based on pixdiablo's gcd answer - http://stackoverflow.com/a/1186465/828681
        common = gcd(self.width, self.height)
        self.ratio = str(self.width / common) + ':' + str(self.height / common)
        self.ratio_error = 0

        # Special case: ratio is not well behaved
        if not self.ratio in accepted_ratios:
            lesser_error = 999
            lesser_index = -1
            my_ratio_normalized = float(self.width) / float(self.height)

            # Check how far from each known aspect this resolution is, and take one with the smaller error
            for i in range(len(accepted_ratios)):
                ratio = accepted_ratios[i].split(':')
                w = float(ratio[0])
                h = float(ratio[1])
                known_ratio_normalized = w / h
                distance = abs(my_ratio_normalized - known_ratio_normalized)
                if (distance < lesser_error):
                    lesser_index = i
                    lesser_error = distance
                    self.ratio_error = distance

            self.ratio = accepted_ratios[lesser_index]

    #-------------------------------------------------------
    def __str__(self):
        descr = str(self.width) + 'x' + str(self.height) + ' - ' + self.ratio + ' - ' + str(self.prevalence) + '%'
        if self.ratio_error > 0:
            descr += ' error: %.2f' % (self.ratio_error * 100) + '%'
        return descr

#-------------------------------------------------------
# Returns a list of ResData
def parse_steam_file(steam_file):
    result = []
    for line in file(steam_file):
        result.append(ResData(line))
    return result

#-------------------------------------------------------
ratios_prevalence = {}
data = parse_steam_file(steam_file)

print('Known Steam resolutions:')
for res in data:
    print(res)
    acc_prevalence = ratios_prevalence[res.ratio] if (res.ratio in ratios_prevalence) else 0
    ratios_prevalence[res.ratio] = acc_prevalence + res.prevalence

# Hack to fix 8:5, more known as 16:10
ratios_prevalence['16:10'] = ratios_prevalence['8:5']
del ratios_prevalence['8:5']

print('\nSteam screen ratio prevalences:')
sorted_ratios = sorted(ratios_prevalence.items(), key=lambda x: x[1], reverse=True)
for value in sorted_ratios:
    print(value[0] + ' -> ' + str(value[1]) + '%')

For the curious, these are the prevalence of screen ratios amongst Steam users (as of October 2012):

16:9 -> 58.9%
16:10 -> 24.0%
5:4 -> 9.57%
4:3 -> 6.38%
5:3 -> 0.84%
17:9 -> 0.11%

shorter version:

found = Value1.StartsWith("abc");

sorry, but I am a stickler for 'less' code.

Given the edit of the questioner I would actually go with something that accepted an offset, this may in fact be a Great place to an Extension method that overloads StartsWith

public static class StackOverflowExtensions
{
    public static bool StartsWith(this String val, string findString, int count)
    {
        return val.Substring(0, count).Contains(findString);
    }
}

For those using Mac and you get a command not found error, what you need to do is

type

./adb install "yourapk.apk"

Compare getApplication() and getApplicationContext().

getApplication returns an Application object which will allow you to manage your global application state and respond to some device situations such as onLowMemory() and onConfigurationChanged().

getApplicationContext returns the global application context - the difference from other contexts is that for example, an activity context may be destroyed (or otherwise made unavailable) by Android when your activity ends. The Application context remains available all the while your Application object exists (which is not tied to a specific Activity) so you can use this for things like Notifications that require a context that will be available for longer periods and independent of transient UI objects.

I guess it depends on what your code is doing whether these may or may not be the same - though in normal use, I'd expect them to be different.

check this out: http://hayageek.com/docs/jquery-upload-file.php I've found it accidentally on the net.

Now it's possible and supported by all major browsers: https://developer.mozilla.org/en-US/docs/Web/API/File/File

var file = new File(["foo"], "foo.txt", {
  type: "text/plain",
});

In android studio you can easily press:

1. Ctrl + Shift + Alt + S.
2. If you have a newer version of android studio, then press on app first. Then, continue with step three as follows.
3. A window will open with a bunch of options
4. Go to Flavors and that's actually all you need

You can also change the versionCode of your app there.

UPDATED

DEMO: http://jsbin.com/uneti3/3

your code is wrong, it should be something like this:

 $(bla).click(function() { 
        var disable =  $target.toggleClass('open').hasClass('open');
       $target.prev().prop("disabled", disable);
  });

you are using the toggleClass function in wrong way

• http://api.jquery.com/toggleClass/

If you have control over the input file, and it's an array of objects, you can solve this more easily. Arrange to output the file with each record on one line, like this:

[
   {"key": value},
   {"key": value},
   ...

This is still valid JSON.

Then, use the node.js readline module to process them one line at a time.

var fs = require("fs");

var lineReader = require('readline').createInterface({
    input: fs.createReadStream("input.txt")
});

lineReader.on('line', function (line) {
    line = line.trim();

    if (line.charAt(line.length-1) === ',') {
        line = line.substr(0, line.length-1);
    }

    if (line.charAt(0) === '{') {
        processRecord(JSON.parse(line));
    }
});

function processRecord(record) {
    // Process the records one at a time here! 
}

The answer varies hugely across different systems and different implementations, but the most important parts are:

1. A thread has an independent thread of execution (i.e. you can context-switch away from it, and then back, and it will resume running where it was).
2. A thread has a lifetime (it can be created by another thread, and another thread can wait for it to finish).
3. It probably has less baggage attached than a "process".

Beyond that: threads could be implemented within a single process by a language runtime, threads could be coroutines, threads could be implemented within a single process by a threading library, or threads could be a kernel construct.

In several modern Unix systems, including Linux which I'm most familiar with, everything is threads -- a process is merely a type of thread that shares relatively few things with its parent (i.e. it gets its own memory mappings, its own file table and permissions, etc.) Reading man 2 clone, especially the list of flags, is really instructive here.

I have the same error, please go to

xampp\phpMyAdmin\libraries\config.default.php

Look for : $cfg['ExecTimeLimit'] = 600;

You can change '600' to any higher value, like '6000'.

Maximum execution time in seconds is (0 for no limit).

This will fix your error.

Using jQuery, you can do it easily:

$("input").addClass("class-name")

Here is your input tag

@Html.EditorFor(model => model.Name)

For DropDownlist you can use this one:

$("select").addClass("class-name")

For Dropdownlist:

@Html.DropDownlistFor(model=>model.Name)

You can create a winform project in VS2005/ VS2008 and then change its properties to be a command line application. It can then be started from the command line, but will still open a winform.

ALTER TABLE can do multiple table alterations in one statement, but MODIFY COLUMN can only work on one column at a time, so you need to specify MODIFY COLUMN for each column you want to change:

ALTER TABLE webstore.Store
  MODIFY COLUMN ShortName VARCHAR(100),
  MODIFY COLUMN UrlShort VARCHAR(100);

Also, note this warning from the manual:

When you use CHANGE or MODIFY, column_definition must include the data type and all attributes that should apply to the new column, other than index attributes such as PRIMARY KEY or UNIQUE. Attributes present in the original definition but not specified for the new definition are not carried forward.

When running the python file, you would normally do this

python app.py

To avoid these messsages. Inside the CLI (Command Line Interface), run these commands.

export FLASK_APP=app.py
export FLASK_RUN_HOST=127.0.0.1
export FLASK_ENV=development
export FLASK_DEBUG=0
flask run

This should work perfectlly. :) :)

To answer the question without reading too much else into it i would

char str[2] = "\0"; /* gives {\0, \0} */
str[0] = fgetc(fp);

You could use the second line in a loop with what ever other string operations you want to keep using char's as strings.

This code works very fast. It comes from here

This will only work for int-digits 0-9, but your question seems to suggest that might be enough.

It works by adding the ASCII value of char '0' to the integer digit.

int i=6;
char c = '0'+i;  // now c is '6'

For example:

'0'+0 = '0'
'0'+1 = '1'
'0'+2 = '2'
'0'+3 = '3'

Edit

It is unclear what you mean, "work for alphabets"? If you want the 5th letter of the alphabet:

int i=5;
char c = 'A'-1 + i; // c is now 'E', the 5th letter.

Note that because in C/Ascii, A is considered the 0th letter of the alphabet, I do a minus-1 to compensate for the normally understood meaning of 5th letter.

Adjust as appropriate for your specific situation.
(and test-test-test! any code you write)

By default, unlike an exception, a warning doesn't interrupt.

After import warnings, it is possible to specify a Warnings class when generating a warning. If one is not specified, it is literally UserWarning by default.

>>> warnings.warn('This is a default warning.')
<string>:1: UserWarning: This is a default warning.

To simply use a preexisting class instead, e.g. DeprecationWarning:

>>> warnings.warn('This is a particular warning.', DeprecationWarning)
<string>:1: DeprecationWarning: This is a particular warning.

Creating a custom warning class is similar to creating a custom exception class:

>>> class MyCustomWarning(UserWarning):
...     pass
... 
... warnings.warn('This is my custom warning.', MyCustomWarning)

<string>:1: MyCustomWarning: This is my custom warning.

For testing, consider assertWarns or assertWarnsRegex.

As an alternative, especially for standalone applications, consider the logging module. It can log messages having a level of debug, info, warning, error, etc. Log messages having a level of warning or higher are by default printed to stderr.

I suspect you might not have Customer.equals() implemented properly (or at all).

List.contains() uses equals() to verify whether any of its elements is identical to the object passed as parameter. However, the default implementation of equals tests for physical identity, not value identity. So if you have not overwritten it in Customer, it will return false for two distinct Customer objects having identical state.

Here are the nitty-gritty details of how to implement equals (and hashCode, which is its pair - you must practically always implement both if you need to implement either of them). Since you haven't shown us the Customer class, it is difficult to give more concrete advice.

As others have noted, you are better off using a Set rather than doing the job by hand, but even for that, you still need to implement those methods.

json.dumps() converts a dictionary to str object, not a json(dict) object! So you have to load your str into a dict to use it by using json.loads() method

See json.dumps() as a save method and json.loads() as a retrieve method.

This is the code sample which might help you understand it more:

import json

r = {'is_claimed': 'True', 'rating': 3.5}
r = json.dumps(r)
loaded_r = json.loads(r)
loaded_r['rating'] #Output 3.5
type(r) #Output str
type(loaded_r) #Output dict

It wraps around.

e.g:

public class Test {

    public static void main(String[] args) {
        int i = Integer.MAX_VALUE;
        int j = Integer.MIN_VALUE;

        System.out.println(i+1);
        System.out.println(j-1);
    }
}

prints

-2147483648
2147483647

This is the same solution as you have probably seen already, but by doing it this way it's more clearer:

>>> num = 3.141592654

>>> print(f"Number: {num:.2f}")

The image you're using is Alpine based, so you can't use apt-get because it's Ubuntu's package manager.

To fix this just use:

apk update and apk add

This validates date like dd-mm-yyyy

([0-2][0-9]|(3)[0-1])(\-)(((0)[0-9])|((1)[0-2]))(\-)([0-9][0-9][0-9][0-9])

This can use with javascript like angular reactive forms

$(document).on('click', 'selector', handler);

Where click is an event name, and handler is an event handler, like reference to a function or anonymous function function() {}

PS: if you know the particular node you're adding dynamic elements to - you could specify it instead of document.

In my case, i only needed it within certain conditions, and to be done easily in HTML:

<input type="checkbox" [style.pointer-events]="(condition == true) ? 'none' : 'auto'"> 

Or in case you need this consistently:

<input type="checkbox" style="pointer-events: none;">

position(). E.G.:

<countNo><xsl:value-of select="position()" /></countNo>

You can override any built-in function by just re-declaring it.

parseFloat = function(a){
  alert(a)
};

Now parseFloat(3) will alert 3.

I have seen JMS used in different commercial and academic projects. JMS can easily come into your picture, whenever you want to have a totally decoupled distributed systems. Generally speaking, when you need to send your request from one node, and someone in your network takes care of it without/with giving the sender any information about the receiver.

In my case, I have used JMS in developing a message-oriented middleware (MOM) in my thesis, where specific types of object-oriented objects are generated in one side as your request, and compiled and executed on the other side as your response.

If you are planning to draw a lot of pixel, it's a lot more efficient to use the image data of the canvas to do pixel drawing.

var canvas = document.getElementById("myCanvas");
var canvasWidth = canvas.width;
var canvasHeight = canvas.height;
var ctx = canvas.getContext("2d");
var canvasData = ctx.getImageData(0, 0, canvasWidth, canvasHeight);

// That's how you define the value of a pixel //
function drawPixel (x, y, r, g, b, a) {
    var index = (x + y * canvasWidth) * 4;

    canvasData.data[index + 0] = r;
    canvasData.data[index + 1] = g;
    canvasData.data[index + 2] = b;
    canvasData.data[index + 3] = a;
}

// That's how you update the canvas, so that your //
// modification are taken in consideration //
function updateCanvas() {
    ctx.putImageData(canvasData, 0, 0);
}

Then, you can use it in this way :

drawPixel(1, 1, 255, 0, 0, 255);
drawPixel(1, 2, 255, 0, 0, 255);
drawPixel(1, 3, 255, 0, 0, 255);
updateCanvas();

For more information, you can take a look at this Mozilla blog post : http://hacks.mozilla.org/2009/06/pushing-pixels-with-canvas/

Firstly, you can del other things besides local variables

del list_item[4]
del dictionary["alpha"]

Both of which should be clearly useful. Secondly, using del on a local variable makes the intent clearer. Compare:

del foo

to

foo = None

I know in the case of del foo that the intent is to remove the variable from scope. It's not clear that foo = None is doing that. If somebody just assigned foo = None I might think it was dead code. But I instantly know what somebody who codes del foo was trying to do.

@Alex Martelli's answer is great! But it work only for one element at time (WHERE name = 'Joan') If you take out the WHERE clause, the query will return all the root rows together...

I changed a little bit for my situation, so it can show the entire tree for a table.

table definition:

CREATE TABLE [dbo].[mar_categories] ( 
    [category]  int IDENTITY(1,1) NOT NULL,
    [name]      varchar(50) NOT NULL,
    [level]     int NOT NULL,
    [action]    int NOT NULL,
    [parent]    int NULL,
    CONSTRAINT [XPK_mar_categories] PRIMARY KEY([category])
)

(level is literally the level of a category 0: root, 1: first level after root, ...)

and the query:

WITH n(category, name, level, parent, concatenador) AS 
(
    SELECT category, name, level, parent, '('+CONVERT(VARCHAR (MAX), category)+' - '+CONVERT(VARCHAR (MAX), level)+')' as concatenador
    FROM mar_categories
    WHERE parent is null
        UNION ALL
    SELECT m.category, m.name, m.level, m.parent, n.concatenador+' * ('+CONVERT (VARCHAR (MAX), case when ISNULL(m.parent, 0) = 0 then 0 else m.category END)+' - '+CONVERT(VARCHAR (MAX), m.level)+')' as concatenador
    FROM mar_categories as m, n
    WHERE n.category = m.parent
)
SELECT distinct * FROM n ORDER BY concatenador asc

(You don't need to concatenate the level field, I did just to make more readable)

the answer for this query should be something like:

I hope it helps someone!

now, I'm wondering how to do this on MySQL... ^^

Vladimir's answer is perfect, but anyone like me who is looking for swift solution

This Solution is Worked for swift version 4.2

var i = 0
    func animation(){
        let name = (i % 2 == 0) ? "1.png" : "2.png"
        myImageView.image = UIImage.init(named: name)
        let transition: CATransition = CATransition.init()
        transition.duration = 1.0
        transition.timingFunction = CAMediaTimingFunction.init(name: .easeInEaseOut)
        transition.type = .fade
        myImageView.layer.add(transition, forKey: nil)
        i += 1
    }

You can call this method from anywhere. It will change the image to next one(image) with animation.

For Swift Version 4.0 Use bellow solution

var i = 0
    func animationVersion4(){
        let name = (i % 2 == 0) ? "1.png" : "2.png"
        uiImage.image = UIImage.init(named: name)
        let transition: CATransition = CATransition.init()
        transition.duration = 1.0
        transition.timingFunction = CAMediaTimingFunction.init(name: kCAMediaTimingFunctionEaseInEaseOut)
        transition.type = kCATransitionFade
        uiImage.layer.add(transition, forKey: nil)
        i += 1
    }

$(function(){    
    if($.browser.msie && $.browser.version <= 9){
        $("[placeholder]").focus(function(){
            if($(this).val()==$(this).attr("placeholder")) $(this).val("");
        }).blur(function(){
            if($(this).val()=="") $(this).val($(this).attr("placeholder"));
        }).blur();

        $("[placeholder]").parents("form").submit(function() {
            $(this).find('[placeholder]').each(function() {
                if ($(this).val() == $(this).attr("placeholder")) {
                    $(this).val("");
                }
            })
        });
    }
});

try this

Need some adjusts but should work for Express v4. Including those routes added with .use().

function listRoutes(routes, stack, parent){

  parent = parent || '';
  if(stack){
    stack.forEach(function(r){
      if (r.route && r.route.path){
        var method = '';

        for(method in r.route.methods){
          if(r.route.methods[method]){
            routes.push({method: method.toUpperCase(), path: parent + r.route.path});
          }
        }       

      } else if (r.handle && r.handle.name == 'router') {
        const routerName = r.regexp.source.replace("^\\","").replace("\\/?(?=\\/|$)","");
        return listRoutes(routes, r.handle.stack, parent + routerName);
      }
    });
    return routes;
  } else {
    return listRoutes([], app._router.stack);
  }
}

//Usage on app.js
const routes = listRoutes(); //array: ["method: path", "..."]

edit: code improvements

Unless you want to go the VBA route to work out the Tab name, the Excel formula is fairly ugly based upon Mid functions, etc. But both these methods can be found here if you want to go that way.

Rather, the way I would do it is:

1) Make one cell on your sheet named, for example, Reference_Sheet and put in that cell the value "Jan Item" for example.

2) Now, use the Indirect function like:

=INDIRECT(Reference_Sheet&"!J3") 

3) Now, for each month's sheet, you just have to change that one Reference_Sheet cell.

Hope this gives you what you're looking for!

Well, you can declare variables inside the Constructor.

class Foo {
    constructor() {
        var name = "foo"
        this.method = function() {
            return name
        }
    }
}

var foo = new Foo()

foo.method()

Here is a condensed replacement for the ConvertToLetter function that in theory should work for all possible positive integers. For example, 1412 produces "BBH" as the result.

Public Function ColumnNumToStr(ColNum As Integer) As String
Dim Value As Integer
Dim Rtn As String
    Rtn = ""
    Value = ColNum - 1
    While Value > 25
        Rtn = Chr(65 + (Value Mod 26)) & Rtn
        Value = Fix(Value / 26) - 1
    Wend
    Rtn = Chr(65 + Value) & Rtn
    ColumnNumToStr = Rtn
End Function

You wont be able to access a local resource from your aspx page (web server). Have you tried a relative path from your aspx page to your css file like so...

<link rel="stylesheet" media="all" href="/CSS/Style.css" type="text/css" />

The above assumes that you have a folder called CSS in the root of your website like this:

http://www.website.com/CSS/Style.css

1. You've got the right idea about how to design your resources, IMHO. I wouldn't change a thing.

2. Rather than trying to extend HTTP with more verbs, consider what your proposed verbs can be reduced to in terms of the basic HTTP methods and resources. For example, instead of an activate_login verb, you could set up resources like: /api/users/1/login/active which is a simple boolean. To activate a login, just PUT a document there that says 'true' or 1 or whatever. To deactivate, PUT a document there that is empty or says 0 or false.

Similarly, to change or set passwords, just do PUTs to /api/users/1/password.

Whenever you need to add something (like a credit) think in terms of POSTs. For example, you could do a POST to a resource like /api/users/1/credits with a body containing the number of credits to add. A PUT on the same resource could be used to overwrite the value rather than add. A POST with a negative number in the body would subtract, and so on.

3. I'd strongly advise against extending the basic HTTP status codes. If you can't find one that matches your situation exactly, pick the closest one and put the error details in the response body. Also, remember that HTTP headers are extensible; your application can define all the custom headers that you like. One application that I worked on, for example, could return a 404 Not Found under multiple circumstances. Rather than making the client parse the response body for the reason, we just added a new header, X-Status-Extended, which contained our proprietary status code extensions. So you might see a response like:

HTTP/1.1 404 Not Found    
X-Status-Extended: 404.3 More Specific Error Here

That way a HTTP client like a web browser will still know what to do with the regular 404 code, and a more sophisticated HTTP client can choose to look at the X-Status-Extended header for more specific information.

4. For authentication, I recommend using HTTP authentication if you can. But IMHO there's nothing wrong with using cookie-based authentication if that's easier for you.

The solution that worked for me, is missing from the list of answers. Hence I am posting this solution here:

File[]dirs = new File("/mypath/mydir/").listFiles((FileFilter)FileFilterUtils.directoryFileFilter());

Here I have used org.apache.commons.io.filefilter.FileFilterUtils from Apache commons-io-2.2.jar. Its documentation is available here: https://commons.apache.org/proper/commons-io/javadocs/api-2.2/org/apache/commons/io/filefilter/FileFilterUtils.html

You can also use as many classes as needed on a tag, but an id must be unique to the document. Also be careful of using too many divs, when another more semantic tag can do the job.

<p id="unique" class="x y z">Styled paragraph</p>

I know this is a while ago but I encountered this and followed the other answers here but to no avail, I found the solution via this question (Stackoverflow Question)

Essentially just needed to edit the php.ini file (mine was found at c:\xampp\php\php.ini) and uncomment these lines...

;extension=php_mysql.dll
;extension=php_mysqli.dll
;extension=php_pdo_mysql.dll

After restarting apache all was working as expected.

Use the ToDictionary method directly.

var result = 
  // as Jon Skeet pointed out, OrderBy is useless here, I just leave it 
  // show how to use OrderBy in a LINQ query
  myClassCollection.OrderBy(mc => mc.SomePropToSortOn)
                   .ToDictionary(mc => mc.KeyProp.ToString(), 
                                 mc => mc.ValueProp.ToString(), 
                                 StringComparer.OrdinalIgnoreCase);

In my case I need to do

sudo npm install  

my project is inside /var/www so I also need to set proper permissions.

Even with Rollin_s's tip, Dave Webb's answer didn't work for me. The text in the right TextView was still overlapping the text in the left TextView.

I eventually got the behavior I wanted with something like this:

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/RelativeLayout01" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"
    android:padding="10dp">

<TextView 
    android:id="@+id/mytextview1"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true" />

<TextView 
    android:id="@+id/mytextview2"
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_toRightOf="@id/mytextview1"
    android:gravity="right"/>

</RelativeLayout>

Note that mytextview2 has "android:layout_width" set as "match_parent".

Hope this helps someone!

From a Powershell script, you can try this. I only had a single version of the assembly in the GAC so this worked just fine.

cd "c:\Windows\Microsoft.NET\assembly\GAC_MSIL\"
Get-ChildItem assemblypath -Recurse -Include *.dll |  Copy-Item -Destination "c:\folder to copy to"

where the assembly path can use wildcards.

Here's a subquery for you!

List<int> IdsToFind = new List<int>() {2, 3, 4};

db.Users
.Where(u => SqlMethods.Like(u.LastName, "%fra%"))
.Where(u =>
    db.CompanyRolesToUsers
    .Where(crtu => IdsToFind.Contains(crtu.CompanyRoleId))
    .Select(crtu =>  crtu.UserId)
    .Contains(u.Id)
)

Regarding this portion of the question:

predicateAnd = predicateAnd.And(c => c.LastName.Contains(
                                TextBoxLastName.Text.Trim()));

I strongly recommend extracting the string from the textbox before authoring the query.

string searchString = TextBoxLastName.Text.Trim();
predicateAnd = predicateAnd.And(c => c.LastName.Contains( searchString));

You want to maintain good control over what gets sent to the database. In the original code, one possible reading is that an untrimmed string gets sent into the database for trimming - which is not good work for the database to be doing.

If you are talking about an actual database (an mdf file) you would Attach it

.sql files are typically run using SQL Server Management Studio. They are basically saved SQL statements, so could be anything. You don't "import" them. More precisely, you "execute" them. Even though the script may indeed insert data.

Also, to expand on Jamie F's answer, don't run a SQL file against your database unless you know what it is doing. SQL scripts can be as dangerous as unchecked exe's

you can use @PrivateOwned to delete orphans e.g

@OneToMany(mappedBy = "masterData", cascade = {
        CascadeType.ALL })
@PrivateOwned

df.filter("location like '%google.com%'")

or with DataFrame column methods

df.filter(df.location.like('%google.com%'))

From a comment:

I want to sort each set.

That's easy. For any set s (or anything else iterable), sorted(s) returns a list of the elements of s in sorted order:

>>> s = set(['0.000000000', '0.009518000', '10.277200999', '0.030810999', '0.018384000', '4.918560000'])
>>> sorted(s)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '10.277200999', '4.918560000']

Note that sorted is giving you a list, not a set. That's because the whole point of a set, both in mathematics and in almost every programming language,* is that it's not ordered: the sets {1, 2} and {2, 1} are the same set.

You probably don't really want to sort those elements as strings, but as numbers (so 4.918560000 will come before 10.277200999 rather than after).

The best solution is most likely to store the numbers as numbers rather than strings in the first place. But if not, you just need to use a key function:

>>> sorted(s, key=float)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '4.918560000', '10.277200999']

For more information, see the Sorting HOWTO in the official docs.

The SSPI context error definitely indicates authentication is being attempted using Kerberos.

Since Kerberos authentication SQL Server's Windows Authentication relies on Active Directory, which requires a thrusted relationship between your computer and your network domain controller, you should start by validating that relationship.

You can quickly check that relationship, thru the following Powershell command Test-ComputerSecureChannel.

Test-ComputerSecureChannel -verbose

If it returns False, you must repair your computer Active Directory secure channel, since without it no domain credencials validation is possible outside your computer.

You can repair your Computer Secure Channel, thru the following Powershell command:

Test-ComputerSecureChannel -Repair

Check the security event logs, if you are using kerberos you should see logon attempts with authentication package: Kerberos.

The NTLM authentication may be failing and so a kerberos authentication attempt is being made. You might also see an NTLM logon attempt failure in your security event log?

You can turn on kerberos event logging in dev to try to debug why the kerberos is failing, although it is very verbose.

Microsoft's Kerberos Configuration Manager for SQL Server may help you quickly diagnose and fix this issue.

Here is a good story to read: http://houseofbrick.com/microsoft-made-an-easy-button-for-spn-and-double-hop-issues/

You cannot use both statements; the datetime module contains a datetime type. The local name datetime in your own module can only refer to one or the other.

Use only import datetime, then make sure that you always use datetime.datetime to refer to the contained type:

import datetime

today_date = datetime.date.today()
date_time = datetime.datetime.strptime(date_time_string, '%Y-%m-%d %H:%M')

Now datetime is the module, and you refer to the contained types via that.

Alternatively, import all types you need from the module:

from datetime import date, datetime

today_date = date.today()
date_time = datetime.strptime(date_time_string, '%Y-%m-%d %H:%M')

Here datetime is the type from the module. date is another type, from the same module.

Turned out to be an issue with Webpack just not resolving an import - talk about horrible horrible error messages :(

// Had to change
import DoISuportIt from 'components/DoISuportIt';

// To (notice the missing `./`)
import DoISuportIt from './components/DoISuportIt';

Here is another example using the lapply and table functions in base R.

freqList = lapply(select_if(tips, is.factor), 
              function(x) {
                  df = data.frame(table(x))

                  df = data.frame(fct = df[, 1], 
                                  n = sapply(df[, 2], function(y) {
                                      round(y / nrow(dat), 2)
                                    }
                                )
                            )
                  return(df) 
                    }
                )

Use print(freqList) to see the proportion tables (percent of frequencies) for each column/feature/variable (depending on your tradecraft) that is labeled as a factor.

I use these:

.right {display:table; margin:-18px 0 0 auto;}
.center {display:table; margin:-18px auto 0 auto;}

The standard colormaps also all have reversed versions. They have the same names with _r tacked on to the end. (Documentation here.)

I do have an article on MSDN - Creating ASP.NET MVC with custom bootstrap theme / layout using VS 2012, VS 2013 and VS 2015, also have a demo code sample attached.. Please refer below link. https://code.msdn.microsoft.com/ASPNET-MVC-application-62ffc106

According to Dangerously Set innerHTML,

Improper use of the innerHTML can open you up to a cross-site scripting (XSS) attack. Sanitizing user input for display is notoriously error-prone, and failure to properly sanitize is one of the leading causes of web vulnerabilities on the internet.

Our design philosophy is that it should be "easy" to make things safe, and developers should explicitly state their intent when performing “unsafe” operations. The prop name dangerouslySetInnerHTML is intentionally chosen to be frightening, and the prop value (an object instead of a string) can be used to indicate sanitized data.

After fully understanding the security ramifications and properly sanitizing the data, create a new object containing only the key __html and your sanitized data as the value. Here is an example using the JSX syntax:

function createMarkup() {
    return {
       __html: 'First · Second'    };
 }; 

<div dangerouslySetInnerHTML={createMarkup()} /> 

Read more about it using below link:

documentation: React DOM Elements - dangerouslySetInnerHTML.

Employees.objects.values_list('eng_name', flat=True)

That creates a flat list of all eng_names. If you want more than one field per row, you can't do a flat list: this will create a list of tuples:

Employees.objects.values_list('eng_name', 'rank')

Have the below js inside the iframe and use ajax to submit the form.

$(function(){

   $("form").submit(e){
        e.preventDefault();

       //Use ajax to submit the form
       $.ajax({
          url: this.action,
          data: $(this).serialize(),
          success: function(){
             window.parent.$("#target").load("urlOfThePageToLoad");
          });
       });

   });

});

You need to set oracle to listen on all ip addresses (by default, it listens only to localhost connections.)

Step 1 - Edit listener.ora

This file is located in:

• Windows: %ORACLE_HOME%\network\admin\listener.ora.
• Linux: $ORACLE_HOME/network/admin/listener.ora

Replace localhost with 0.0.0.0

# ...

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))
    )
  )

# ...

Step 2 - Restart Oracle services

• Windows: WinKey + r

  services.msc
  

• Linux (CentOs):

  sudo systemctl restart oracle-xe
  

I'm not entirely certain myself, I recall seeing jQuery did it to an extent, but it doesn't handle hierarchical records at all, let alone in a php friendly way.

One thing I do know for certain, is when building URLs and sticking the product into the dom, don't just use string-glue to do it, or you'll be opening yourself to a handy page breaker.

For instance, certain advertising software in-lines the version string from whatever runs your flash. This is fine when its adobes generic simple string, but however, that's very naive, and blows up in an embarrasing mess for people whom have installed Gnash, as gnash'es version string happens to contain a full blown GPL copyright licences, complete with URLs and <a href> tags. Using this in your string-glue advertiser generator, results in the page blowing open and having imbalanced HTML turning up in the dom.

The moral of the story:

   var foo = document.createElement("elementnamehere"); 
   foo.attribute = allUserSpecifiedDataConsideredDangerousHere; 
   somenode.appendChild(foo); 

Not:

   document.write("<elementnamehere attribute=\"" 
        + ilovebrokenwebsites 
        + "\">" 
        + stringdata 
        + "</elementnamehere>");

_{Google need to learn this trick. I tried to report the problem, they appear not to care.}

@Entity is useful with model classes to denote that this is the entity or table

@Table is used to provide any specific name to your table if you want to provide any different name

Note: if you don't use @Table then hibernate consider that @Entity is your table name by default and @Entity must

@Entity    
@Table(name = "emp")     
public class Employee implements java.io.Serializable    
{

}

I have met same problem. In my case I had no ..\data dir in my C:\mysql\ so I just executed mysqld --initialize command from c:\mysql\bin\ directory and I got the data directory in c:\mysql\data. Afterwards I could use mysqld.exe --console command to test the server startup.

string hostname = "localhost";
int portno = 9081;
IPAddress ipa = (IPAddress) Dns.GetHostAddresses(hostname)[0];


try

    System.Net.Sockets.Socket sock = new System.Net.Sockets.Socket(System.Net.Sockets.AddressFamily.InterNetwork, System.Net.Sockets.SocketType.Stream, System.Net.Sockets.ProtocolType.Tcp);
    sock.Connect(ipa, portno);
    if (sock.Connected == true)  // Port is in use and connection is successful
            MessageBox.Show("Port is Closed");
    sock.Close();

}
catch (System.Net.Sockets.SocketException ex)
{
    if (ex.ErrorCode == 10061)  // Port is unused and could not establish connection 
        MessageBox.Show("Port is Open!");
    else
        MessageBox.Show(ex.Message);
}

Here is my approach- download the freemind and CAM XML Template Editor. Then open CAM XML, create new Template from XML, View -> View Template As Mind Map
Pros of this solution:

• It works locally, so secret files can be processed,
• totally free of charge,
• open source.

Cons:

• Quite unstable with large (more than 20sh MB) files.

Pat Notz is correct. You can get the commit back so long as it's been within a few days. git only garbage collects after about a month or so unless you explicitly tell it to remove newer blobs.

$ git init
Initialized empty Git repository in .git/

$ echo "testing reset" > file1
$ git add file1
$ git commit -m 'added file1'
Created initial commit 1a75c1d: added file1
 1 files changed, 1 insertions(+), 0 deletions(-)
 create mode 100644 file1

$ echo "added new file" > file2
$ git add file2
$ git commit -m 'added file2'
Created commit f6e5064: added file2
 1 files changed, 1 insertions(+), 0 deletions(-)
 create mode 100644 file2

$ git reset --hard HEAD^
HEAD is now at 1a75c1d... added file1

$ cat file2
cat: file2: No such file or directory

$ git reflog
1a75c1d... HEAD@{0}: reset --hard HEAD^: updating HEAD
f6e5064... HEAD@{1}: commit: added file2

$ git reset --hard f6e5064
HEAD is now at f6e5064... added file2

$ cat file2
added new file

You can see in the example that the file2 was removed as a result of the hard reset, but was put back in place when I reset via the reflog.

Here is a TryParse extension method based on Habib's answer:

public static bool TryParse(this string strInput, out JToken output)
{
    if (String.IsNullOrWhiteSpace(strInput))
    {
        output = null;
        return false;
    }
    strInput = strInput.Trim();
    if ((strInput.StartsWith("{") && strInput.EndsWith("}")) || //For object
        (strInput.StartsWith("[") && strInput.EndsWith("]"))) //For array
    {
        try
        {
            output = JToken.Parse(strInput);
            return true;
        }
        catch (JsonReaderException jex)
        {
            //Exception in parsing json
            //optional: LogError(jex);
            output = null;
            return false;
        }
        catch (Exception ex) //some other exception
        {
            //optional: LogError(ex);
            output = null;
            return false;
        }
    }
    else
    {
        output = null;
        return false;
    }
}

Usage:

JToken jToken;
if (strJson.TryParse(out jToken))
{
    // work with jToken
}
else
{
    // not valid json
}

If you want to generate 100 numbers that are random, but each number appearing only once, a good way would be to generate an array with the numbers in order, then shuffle it.

Something like this:

$arr = array();

for ($i=1;$i<=101;$i++) {
    $arr[] = $i;
}

shuffle($arr);

print_r($arr);

Output will look something like this:

Try this

In addition to the answer of BalusC, use the following Java RegExp to replace && with and:

Search:  (#\{[^\}]*)(&&)([^\}]*\})
Replace: $1and$3

You have run this regular expression replacement multiple times to find all occurences in case you are using >2 literals in your EL expressions. Mind to replace the leading # by $ if your EL expression syntax differs.

I was trying to call setErrors() inside a ngModelChange handler in a template form. It did not work until I waited one tick with setTimeout():

template:

<input type="password" [(ngModel)]="user.password" class="form-control" 
 id="password" name="password" required (ngModelChange)="checkPasswords()">

<input type="password" [(ngModel)]="pwConfirm" class="form-control"
 id="pwConfirm" name="pwConfirm" required (ngModelChange)="checkPasswords()"
 #pwConfirmModel="ngModel">

<div [hidden]="pwConfirmModel.valid || pwConfirmModel.pristine" class="alert-danger">
   Passwords do not match
</div>

component:

@ViewChild('pwConfirmModel') pwConfirmModel: NgModel;

checkPasswords() {
  if (this.pwConfirm.length >= this.user.password.length &&
      this.pwConfirm !== this.user.password) {
    console.log('passwords do not match');
    // setErrors() must be called after change detection runs
    setTimeout(() => this.pwConfirmModel.control.setErrors({'nomatch': true}) );
  } else {
    // to clear the error, we don't have to wait
    this.pwConfirmModel.control.setErrors(null);
  }
}

Gotchas like this are making me prefer reactive forms.

Use the -s or --strategy option combined with the -X option. In your specific question, you want to keep all of the remote files and replace the local files of the same name.

Replace conflicts with the remote version

git merge -s recursive -Xtheirs upstream/master  

will use the remote repo version of all conflicting files.

Replace conflicts with the local version

git merge -s recursive -Xours upstream/master

will use the local repo version of all conflicting files.

Something like this should do it :

UPDATE table1 
   SET table1.Price = table2.price 
   FROM table1  INNER JOIN  table2 ON table1.id = table2.id

You can also try this:

UPDATE table1 
   SET price=(SELECT price FROM table2 WHERE table1.id=table2.id);

In my case, i tried all solutions but nothing worked.

My SO is windows 7 x64, with all the Redistributable Packages (x86,x64 / 2010,2013,2015)

The problem was that i tried to install the x64 workbench, but for some reason did not work (even my SO is x64).

so, the solution was download the x86 installer from : https://downloads.mysql.com/archives/workbench/

Tested on Bootstrap 3.3.6 - work's!

$('.nav a').click(function () {_x000D_

From the manual entry for PDOStatement::bindParam:

[With bindParam] Unlike PDOStatement::bindValue(), the variable is bound as a reference and will only be evaluated at the time that PDOStatement::execute() is called.

So, for example:

$sex = 'male';
$s = $dbh->prepare('SELECT name FROM students WHERE sex = :sex');
$s->bindParam(':sex', $sex); // use bindParam to bind the variable
$sex = 'female';
$s->execute(); // executed with WHERE sex = 'female'

or

$sex = 'male';
$s = $dbh->prepare('SELECT name FROM students WHERE sex = :sex');
$s->bindValue(':sex', $sex); // use bindValue to bind the variable's value
$sex = 'female';
$s->execute(); // executed with WHERE sex = 'male'

In addition to Mr. Yankowsky's answers, you could also use postDelayed(). This is available on any View (e.g., your card) and takes a Runnable and a delay period. It executes the Runnable after that delay.

This API has been available for a long time and enables to get access to market data (including live) if you are running a Bloomberg Terminal or have access to a Bloomberg Server, which is chargeable.

The only difference is that the API (not its code) has been open sourced, so it can now be used as a dependency in an open source project for example, without any copyrights issues, which was not the case before.

Use -1 as the start position:

INSTR('JD-EQ-0001', '-', -1)

How about custom module based .htaccess script (like its used in CodeIgniter)? I tried and it worked good in CodeIgniter apps. Any ideas to use it on other apps?

<IfModule authz_core_module>
    Require all denied
</IfModule>
<IfModule !authz_core_module>
    Deny from all
</IfModule>

Yes, mysql_fetch_array() only returns one result. If you want to retrieve more than one row, you need to put the function call in a while loop.

Two examples:

This will only return the first row

$row = mysql_fetch_array($result);

This will return one row on each loop, until no more rows are available from the result set

while($row = mysql_fetch_array($result))
{
    //Do stuff with contents of $row
}

Try this code:

final List<String> list = new ArrayList<String>();
list.add("Item 1");
list.add("Item 2");
list.add("Item 3");
list.add("Item 4");
list.add("Item 5");

final String[] str = {"Report 1", "Report 2", "Report 3", "Report 4", "Report 5"};

final Spinner sp1 = (Spinner) findViewById(R.id.spinner1);
final Spinner sp2 = (Spinner) findViewById(R.id.spinner2);

ArrayAdapter<String> adp1 = new ArrayAdapter<String>(this,
                              android.R.layout.simple_list_item_1, list);
adp1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sp1.setAdapter(adp1);

ArrayAdapter<String> adp2 = new ArrayAdapter<String>(this,
                                  android.R.layout.simple_spinner_item, str);
adp2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sp2.setAdapter(adp2);

sp1.setOnItemSelectedListener(new OnItemSelectedListener()
    {
        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1, int position, long id) {
            // TODO Auto-generated method stub
            Toast.makeText(getBaseContext(), list.get(position), Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub
        }
    });

sp2.setOnItemSelectedListener(new OnItemSelectedListener()
    {
        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1, int position, long id) {
            // TODO Auto-generated method stub
            Toast.makeText(getBaseContext(), str[position], Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub
        }
    });

You can also add spinner item value through String array xml file..

<resources>
    <string name="app_name">Spinner_ex5</string>
    <string name="hello_world">Hello world!</string>
    <string name="menu_settings">Settings</string>
    <string name="title_activity_main">MainActivity</string>
    <string-array name="str2">
        <item>Data 1</item>
        <item>Data 2</item>
        <item>Data 3</item>
        <item>Data 4</item>
        <item>Data 5</item>
    </string-array>
</resources>

In mainActivity.java:

final Spinner sp3 = (Spinner) findViewById(R.id.spinner3);
ArrayAdapter<CharSequence> adp3 = ArrayAdapter.createFromResource(this,
                                    R.array.str2, android.R.layout.simple_list_item_1);

adp3.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sp3.setAdapter(adp3);
sp3.setOnItemSelectedListener(new OnItemSelectedListener()
    {
        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1, int position, long id) {
            // TODO Auto-generated method stub
            String ss = sp3.getSelectedItem().toString();
            Toast.makeText(getBaseContext(), ss, Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub
        }
    });

Escaping strings can be tricky - especially if you want to take unicode into account. I suppose XML is one of the simpler formats/languages to escape but still. I would recommend taking a look at the StringEscapeUtils class in Apache Commons Lang, and its handy escapeXml method.

This happened to me in a React Native project when I was renaming an app's bundle ID, and it clashed with another bundle ID that I'd already used before. I fixed it by performing a re-install:

1. Find the app on the simulator's home screen, then long-press on its app icon, and press App info, then choose "UNINSTALL".

2. Execute react-native run android.

First, keep in mind that, in its precise definition, a module is an object in the memory of a Python interpreter, often created by reading one or more files from disk. While we may informally call a disk file such as a/b/c.py a "module," it doesn't actually become one until it's combined with information from several other sources (such as sys.path) to create the module object.

(Note, for example, that two modules with different names can be loaded from the same file, depending on sys.path and other settings. This is exactly what happens with python -m my.module followed by an import my.module in the interpreter; there will be two module objects, __main__ and my.module, both created from the same file on disk, my/module.py.)

A package is a module that may have submodules (including subpackages). Not all modules can do this. As an example, create a small module hierarchy:

$ mkdir -p a/b
$ touch a/b/c.py

Ensure that there are no other files under a. Start a Python 3.4 or later interpreter (e.g., with python3 -i) and examine the results of the following statements:

import a
a                ? <module 'a' (namespace)>
a.b              ? AttributeError: module 'a' has no attribute 'b'
import a.b.c
a.b              ? <module 'a.b' (namespace)>
a.b.c            ? <module 'a.b.c' from '/home/cjs/a/b/c.py'>

Modules a and a.b are packages (in fact, a certain kind of package called a "namespace package," though we wont' worry about that here). However, module a.b.c is not a package. We can demonstrate this by adding another file, a/b.py to the directory structure above and starting a fresh interpreter:

import a.b.c
? ImportError: No module named 'a.b.c'; 'a.b' is not a package
import a.b
a                ? <module 'a' (namespace)>
a.__path__       ? _NamespacePath(['/.../a'])
a.b              ? <module 'a.b' from '/home/cjs/tmp/a/b.py'>
a.b.__path__     ? AttributeError: 'module' object has no attribute '__path__'

Python ensures that all parent modules are loaded before a child module is loaded. Above it finds that a/ is a directory, and so creates a namespace package a, and that a/b.py is a Python source file which it loads and uses to create a (non-package) module a.b. At this point you cannot have a module a.b.c because a.b is not a package, and thus cannot have submodules.

You can also see here that the package module a has a __path__ attribute (packages must have this) but the non-package module a.b does not.

import java.security.MessageDigest

val digest = MessageDigest.getInstance("MD5")

//Quick MD5 of text
val text = "MD5 this text!"
val md5hash1 = digest.digest(text.getBytes).map("%02x".format(_)).mkString

//MD5 of text with updates
digest.update("MD5 ".getBytes())
digest.update("this ".getBytes())
digest.update("text!".getBytes())
val md5hash2 = digest.digest().map(0xFF & _).map("%02x".format(_)).mkString

//Output
println(md5hash1 + " should be the same as " + md5hash2)

I'm sure this isn't as fast as the solutions using Pandas or Numpy operations, but if you don't want to rewrite your function you can use map. Using the original example data -

import pandas as pd

df = pd.DataFrame({'ID':['1','2','3'], 'col_1': [0,2,3], 'col_2':[1,4,5]})
mylist = ['a','b','c','d','e','f']

def get_sublist(sta,end):
    return mylist[sta:end+1]

df['col_3'] = list(map(get_sublist,df['col_1'],df['col_2']))
#In Python 2 don't convert above to list

We could pass as many arguments as we wanted into the function this way. The output is what we wanted

ID  col_1  col_2      col_3
0  1      0      1     [a, b]
1  2      2      4  [c, d, e]
2  3      3      5  [d, e, f]

Here's my approach, which simply splits a string by spaces, then for loops the array and increases the count if the array[i] matches a given regex pattern.

    function wordCount(str) {
        var stringArray = str.split(' ');
        var count = 0;
        for (var i = 0; i < stringArray.length; i++) {
            var word = stringArray[i];
            if (/[A-Za-z]/.test(word)) {
                count++
            }
        }
        return count
    }

Invoked like so:

var str = "testing strings here's a string --..  ? // ... random characters ,,, end of string";
wordCount(str)

(added extra characters & spaces to show accuracy of function)

The str above returns 10, which is correct!

The list method index will return -1 if the item is not present, and will return the index of the item in the list if it is present. Alternatively in an if statement you can do the following:

if myItem in list:
    #do things

You can also check if an element is not in a list with the following if statement:

if myItem not in list:
    #do things

Open Task Manager and Kill both of these processes. They will autostart back up. Then try debugging your project again.

UnderscoreJs has a function that does that, underscorejs.org/#once

  // Returns a function that will be executed at most one time, no matter how
  // often you call it. Useful for lazy initialization.
  _.once = function(func) {
    var ran = false, memo;
    return function() {
      if (ran) return memo;
      ran = true;
      memo = func.apply(this, arguments);
      func = null;
      return memo;
    };
  };

I wouldn't bother looking for ASP.NET stuff specifically (probably won't find any anyways). Finding a good CSS theme easily can be used in ASP.NET.

Here's some sites that I love for CSS goodness:

http://www.oswd.org/
http://www.openwebdesign.org/
http://www.styleshout.com/

Yes, you can achieve it by find_elements_by_css_selector("*") or find_elements_by_xpath(".//*").

However, this doesn't sound like a valid use case to find all children of an element. It is an expensive operation to get all direct/indirect children. Please further explain what you are trying to do. There should be a better way.

from selenium import webdriver

driver = webdriver.Firefox()
driver.get("http://www.stackoverflow.com")

header = driver.find_element_by_id("header")

# start from your target element, here for example, "header"
all_children_by_css = header.find_elements_by_css_selector("*")
all_children_by_xpath = header.find_elements_by_xpath(".//*")

print 'len(all_children_by_css): ' + str(len(all_children_by_css))
print 'len(all_children_by_xpath): ' + str(len(all_children_by_xpath))

I've put together a function that behaves identically to hist in the default case, but accepts the log argument. It uses several tricks from other posters, but adds a few of its own. hist(x) and myhist(x) look identical.

The original problem would be solved with:

myhist(mydata$V3, breaks=c(0,1,2,3,4,5,25), log="xy")

The function:

myhist <- function(x, ..., breaks="Sturges",
                   main = paste("Histogram of", xname),
                   xlab = xname,
                   ylab = "Frequency") {
  xname = paste(deparse(substitute(x), 500), collapse="\n")
  h = hist(x, breaks=breaks, plot=FALSE)
  plot(h$breaks, c(NA,h$counts), type='S', main=main,
       xlab=xlab, ylab=ylab, axes=FALSE, ...)
  axis(1)
  axis(2)
  lines(h$breaks, c(h$counts,NA), type='s')
  lines(h$breaks, c(NA,h$counts), type='h')
  lines(h$breaks, c(h$counts,NA), type='h')
  lines(h$breaks, rep(0,length(h$breaks)), type='S')
  invisible(h)
}

Exercise for the reader: Unfortunately, not everything that works with hist works with myhist as it stands. That should be fixable with a bit more effort, though.

That question solved a quite similar question for me and I thought I should share :

In raw python you can use sum() to count True values in a list :

>>> sum([True,True,True,False,False])
3

But this won't work :

>>> sum([[False, False, True], [True, False, True]])
TypeError...

You can disable certificate checking globally - no matter which package you are using for making requests - like this:

// Disable certificate errors globally
// (ES6 imports (eg typescript))
//
import * as https from 'https'
https.globalAgent.options.rejectUnauthorized = false

Or

// Disable certificate errors globally
// (vanilla nodejs)
//
require('https').globalAgent.options.rejectUnauthorized = false

Of course you shouldn't do this - but it's certainly handy for debugging and/or very basic scripting where you absolutely don't care about certificates being validated correctly.

If you really really want performance you can go the code generation route.

You can do this on your on by doing your own reflection and building a mixin AspectJ ITD.

Or you can use Spring Roo and make a Spring Roo Addon. Your Roo addon will do something similar to the above but will be available to everyone who uses Spring Roo and you don't have to use Runtime Annotations.

I have done both. People crap on Spring Roo but it really is the most comprehensive code generation for Java.

Actually the minimum amount of Angular to be used (as requested in the original question) is just adding a class to the DOM element when show variable is true, and perform the animation/transition via CSS.

So your minimum Angular code is this:

<div class="box-opener" (click)="show = !show">
    Open/close the box
</div>

<div class="box" [class.opened]="show">
    <!-- Content -->
</div>

With this solution, you need to create CSS rules for the transition, something like this:

.box {
    background-color: #FFCC55;
    max-height: 0px;
    overflow-y: hidden;
    transition: ease-in-out 400ms max-height;
}

.box.opened {
    max-height: 500px;
    transition: ease-in-out 600ms max-height;
}

If you have retro-browser-compatibility issues, just remember to add the vendor prefixes in the transitions.

See the example here

For selecting within single quotes use vi'.

For selecting within parenthesis use vi(.

ImageMagick and GD can handle PNGs too; heck, you could even do stuff with nothing but gdk-pixbuf. Are you looking for a graphical editor, or scriptable/embeddable libraries?

Update: More useful information What does <meta http-equiv="X-UA-Compatible" content="IE=edge"> do?

Maybe this url can help you: Activating Browser Modes with Doctype

Edit: Today we were able to override the compatibility view with: <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />

This worked for me:

=(col_name]/60/60/24)+(col_name-1)

import React from 'react';              <--as normal
import PropTypes from 'prop-types';     <--add this as a second line

    App.propTypes = {
        monkey: PropTypes.string,           <--omit "React."
        cat: PropTypes.number.isRequired    <--omit "React."
    };

    Wrong:  React.PropTypes.string
    Right:  PropTypes.string

There is no "Syntax Error" in the code above - it either ocurred in some other line (the above is not all of your code, as there are no imports, neither the declaration of your path variable) or you got some other error type.

The example above worked fine for me, testing on the interactive interpreter.

You don't mention what language you want to track these in, but I found two for javascript:

http://www.cambiaresearch.com/c4/702b8cd1-e5b0-42e6-83ac-25f0306e3e25/Javascript-Char-Codes-Key-Codes.aspx

Very well done and answered here - http://www.sitepoint.com/css3-transform-background-image/

#myelement:before
{
    content: "";
    position: absolute;
    width: 200%;
    height: 200%;
    top: -50%;
    left: -50%;
    z-index: -1;
    background: url(background.png) 0 0 repeat;
    -webkit-transform: rotate(30deg);
    -moz-transform: rotate(30deg);
    -ms-transform: rotate(30deg);
    -o-transform: rotate(30deg);
    transform: rotate(30deg);
}

Felipsmartins is correct.

It is worth mentioning that it is because you cannot really use the -d/--data option if this is not a POST request. But this is still possible if you use the -G option.

Which means you can do this:

curl -X DELETE -G 'http://localhost:5000/locations' -d 'id=3'

Here it is a bit silly but when you are on the command line and you have a lot of parameters, it is a lot tidier.

I am saying this because cURL commands are usually quite long, so it is worth making it on more than one line escaping the line breaks.

curl -X DELETE -G \
'http://localhost:5000/locations' \
-d id=3 \
-d name=Mario \
-d surname=Bros

This is obviously a lot more comfortable if you use zsh. I mean when you need to re-edit the previous command because zsh lets you go line by line. (just saying)

Hope it helps.

You appear to have a heredoc containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF

or if BUILDING is $2 in your script:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF

If your file.sql had an exit at the end then it would be even simpler as you wouldn't need the heredoc:

sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2

In your SQL you can then refer to the position parameters using substitution variables:

...
}',SEM_Models('&1'),NULL,
...

The &1 will be replaced with the first value passed to the SQL script, BUILDING; because that is a string it still needs to be enclosed in quotes. You might want to set verify off to stop if showing you the substitutions in the output.

You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1, the second is &2, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF

or:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF

If total_count is being passed to your shell script then just use its positional parameter, $4 or whatever. And your SQL would then be:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:

define MY_ALIAS = &1
define MY_MODEL = &2

SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

From your separate question, maybe you just wanted:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

... so the alias will be the same value you're querying on (the value in $2, or BUILDING in the original part of the answer). You can refer to a substitution variable as many times as you want.

That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:

select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT

If you set pages 0 and set heading off, your repeated calls might appear in a neat list. You might also need to set tab off and possibly use rpad('&1', 20) or similar to make that column always the same width. Or get the results as CSV with:

select '&1' ||','|| COUNT(*)

Depends what you're using the results for...

Liviu's answer was extremely helpful for me. Hope this is not bad form but i made a fiddle that may help someone else out in the future.

Two important pieces that are needed are:

    $scope.entities = [{
    "title": "foo",
    "id": 1
}, {
    "title": "bar",
    "id": 2
}, {
    "title": "baz",
    "id": 3
}];
$scope.selected = [];

Simple way in Java

public void resize(String inputImagePath,
            String outputImagePath, int scaledWidth, int scaledHeight)
            throws IOException {
        // reads input image
        File inputFile = new File(inputImagePath);
        BufferedImage inputImage = ImageIO.read(inputFile);
 
        // creates output image
        BufferedImage outputImage = new BufferedImage(scaledWidth,
                scaledHeight, inputImage.getType());
 
        // scales the input image to the output image
        Graphics2D g2d = outputImage.createGraphics();
        g2d.drawImage(inputImage, 0, 0, scaledWidth, scaledHeight, null);
        g2d.dispose();
 
        // extracts extension of output file
        String formatName = outputImagePath.substring(outputImagePath
                .lastIndexOf(".") + 1);
 
        // writes to output file
        ImageIO.write(outputImage, formatName, new File(outputImagePath));
    }

Here is a more complete example.

Autowire Environment

First you will want to autowire the environment bean.

@Autowired
private Environment environment;

Check if Profiles exist in Active Profiles

Then you can use getActiveProfiles() to find out if the profile exists in the list of active profiles. Here is an example that takes the String[] from getActiveProfiles(), gets a stream from that array, then uses matchers to check for multiple profiles(Case-Insensitive) which returns a boolean if they exist.

//Check if Active profiles contains "local" or "test"
if(Arrays.stream(environment.getActiveProfiles()).anyMatch(
   env -> (env.equalsIgnoreCase("test") 
   || env.equalsIgnoreCase("local")) )) 
{
   doSomethingForLocalOrTest();
}
//Check if Active profiles contains "prod"
else if(Arrays.stream(environment.getActiveProfiles()).anyMatch(
   env -> (env.equalsIgnoreCase("prod")) )) 
{
   doSomethingForProd();
}

You can also achieve similar functionality using the annotation @Profile("local") Profiles allow for selective configuration based on a passed-in or environment parameter. Here is more information on this technique: Spring Profiles

This is an answer I haven't seen much around (this it was in a comment somewhere) although yes taking the app off development mode will work this can be bad for security or really annoying if the app isn't ready yet but you need to submit the app for review on account of needing access to special permissions (e.g. user_birthday).

What I did instead to fix the error was go to https://developers.facebook.com/sa/apps/{appId}/roles/ or from the app dashboard click roles on the left side

Then add the user account(s) to either developer or tester. Developers will need to be verified by mobile and will get access to the app to make changes but a tester will only need to be verified by email (not sure if even this is necessary but it probably is) and will only be able to use the API instead of make changes to settings.

If the app is ready for the public, obviously just take the app off development mode.

You can parse the pom file with JDOM (http://www.jdom.org/).

If notepad is already started, you should write:

// import the function in your class
[DllImport ("User32.dll")]
static extern int SetForegroundWindow(IntPtr point);

//...

Process p = Process.GetProcessesByName("notepad").FirstOrDefault();
if (p != null)
{
    IntPtr h = p.MainWindowHandle;
    SetForegroundWindow(h);
    SendKeys.SendWait("k");
}

GetProcessesByName returns an array of processes, so you should get the first one (or find the one you want).

If you want to start notepad and send the key, you should write:

Process p = Process.Start("notepad.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");

The only situation in which the code may not work is when notepad is started as Administrator and your application is not.

            If Val(dimcalvalue) >= 50 Then
                text.Text = Val(text.Text) - Val(Last3)

From android API Level 19, when I want to instance JSONArray object I put JSONObject directly as parameter like below:

JSONArray jsonArray=new JSONArray(jsonObject);

JSONArray has constructor to accept object.

In Chrome Dev Tools you can run the following:

Based on luttken's answer. Thought I'd add my twist :)

function dateIsInBetween(\DateTime $from, \DateTime $to, \DateTime $subject)

    return $subject->getTimestamp() > $from->getTimestamp() && $subject->getTimestamp() < $to->getTimestamp() ? true : false;
}

$paymentDate       = new \DateTime('now');
$contractDateBegin = new \DateTime('01/01/2001');
$contractDateEnd   = new \DateTime('01/01/2016');

echo dateIsInBetween($contractDateBegin, $contractDateEnd, $paymentDate) ? "is between" : "NO GO!";

If you want to use the GUI... click/double-click the table and select the Data tab. Click in the column value you want to set to (null). Select the value and delete it. Hit the commit button (green check-mark button). It should now be null.

How to use the SQL Worksheet in SQL Developer to Insert, Update and Delete Data

I find myself using boost::lexical_cast for this sort of thing all the time these days. Example:

std::string input;
std::getline(std::cin,input);
int input_value;
try {
  input_value=boost::lexical_cast<int>(input));
} catch(boost::bad_lexical_cast &) {
  // Deal with bad input here
}

The pattern works just as well for your own classes too, provided they meet some simple requirements (streamability in the necessary direction, and default and copy constructors).

There are multiple easy ways.

1. Just touch web.xml of any webapp.

   touch /usr/share/tomcat/webapps/<WEBAPP-NAME>/WEB-INF/web.xml
   

You can also update a particular jar file in WEB-INF/lib and then touch web.xml, rather than building whole war file and deploying it again.

2. Delete webapps/YOUR_WEB_APP directory, Tomcat will start deploying war within 5 seconds (assuming your war file still exists in webapps folder).

3. Generally overwriting war file with new version gets redeployed by tomcat automatically. If not, you can touch web.xml as explained above.

4. Copy over an already exploded "directory" to your webapps folder

Java based workflow engines like Activiti, Bonita or jBPM support a wide range of the BPMN 2.0 specification. Therefore, you can model processes in a graphical way. In addition, some of those engines have simulation capabilities like Activiti (with Activiti Crystalball). If you code the processes on your own, you aren´t as flexible when you need to change the process. Therefore, I would also advice to use a java based BPM engine.

I did a research concerning BPMN 2.0 based Open Source Engines. Here are the key-points which were relevant for our concrete use case:

1. Bonita:

Bonita has a zero-coding approach which means that they provide an easy to use IDE to build your processes without the need for coding. To achieve that, Bonita has the concept of connectors. For example, if you want to consume a web service, they provide you with a graphical wizzard. The downside is that you have to write the plain XML SOAP-envelope manually and copy it in a graphical textbox. The problem with this approach is that you only can realize use cases which are intended by Bonita. If you want to integrate a system which Bonita did not developed a connector for, you have to code such a connector on your own which is very painful. For example, Bonita offers a SOAP connector for consuming SOAP web services. This connector only works with SOAP 1.2, but not for SOAP 1.1 (http://community.bonitasoft.com/answers/consume-soap-11-webservices-bonita-secure-web-service-connector). If you have a legacy application with SOAP 1.1, you cannot integrate this system easily in your process. The same is true for databases. There are only a few database connectors for dedicated database versions. If you have a version not matching to a connector, you have to code this on your own.

In addition, Bonita has no support for LDAP or Active Directory Sync in the free community edition which is quite a showstopper for a production environment. Another thing to consider is that Bonita is licensed under the GPL / LGPL license which could cause problems when you want to integrate Bonita in another enterprise application. In addition, the community support is very weak. There are several posts which are more than 2 years old and those posts are still not answered.

Another important thing is Business-IT-Alignment. Modelling processes is a collaborative discipline in which IT AND the business analysts are involed. That is why you need adequate tools for both user groups (e.g. an Eclipse Plugin for the developers and an easy to use web modeler for the business people). Bonita only offers Bonita Studio, which needs to be installed on your machine. This IDE is quite technical and not suitable for business users. Therefore, it is very hard to realize Business-IT-Alignment with Bonita.

Bonita is a BPM tool for very trivial and easy processes. Because of the zero-coding approach, the lerning curve is very low and you can start modelling very fast. You need less programming skills and you are able to realize your processes without the need of coding. But as soon as your processes become very complex, Bonita might not be the best solution because of the lack of flexibility. You only can realize use cases which are intended by Bonita.

2. jBPM:

jBPM is a very powerful Open Source BPM Engine which has a lot of features. The web modeler even supports prefabricated models of some van der Aalst workflow patterns (workflowpatterns.com). Business-IT-Alignment is realizable because jBPM offers an Eclipse integration as well as a web-based modeler. A bit tricky is that you only can define forms in the web modeler, but not in the Eclipse Plugin, as far as I know. To sum up, jBPM is a good candidate for using in a company. Our showstopper was the scalability. jBPM is based on the Rules-Engine Drools. This leads to the fact that whole process instances are persisted as BLOBS in the database. This is a critial showstopper when you consider searching and scalability.

In addition, the learning curve is very high because of the complexity. jBPM does not offer a Service Task like the BPMN-Standard suggests In contrast, you have to define your own Java Service tasks and you have to register them manually in the engine, which results in quite low level programming.

3. Activiti:

In the end, we went with Activiti because this is a very easy to use framework-based engine. It offers an Eclipse Plugin as well as a modern AngularJS Web-Modeler. In this way, you can realize Business-IT-Alignment. The REST-API is secured by Spring Security which means that you can extend the Engine very easily with Single Sign-on features. Because of the Apache License 2.0, there is no copyleft which means you are completely free in terms of usage and extensibility which is very important in a productive environment.

In addition, the BPMN-coverage is very good. Not all BPMN-elements are realized, but I do not know any engine which does that.

The Activiti Explorer is a demo frontend which demonstrates the usage of the Activiti APIs. Since this frontend is based on VAADIN, it can be extended very easily. The community is very active which means that you can get help very fast if you have any problems.

Activiti offers good integration points for external form-technologies which is very important for a productive usage. The form-technologies of all candidates are very restrictive. Therefore, it makes sense to use a standard form-technology like XForms in combination with the Engine. Even such more complex things are realizable via the formKey-Attribute.

Activiti does not follow the zero-coding approach which means that you will need a bit of coding if you want to orchestrate services. But even the communication with SOAP services can be achieved by using a Java Service Task and Apache CXF. The coding effort is low.

I hope that my key points can help by taking a decision. To be clear, this is no advertisment for Activiti. The right product choice depends on the concrete use cases. I only want to point out the most important points in our project

set can help you filter out the elements from the list that are duplicates. It will work well for str, int or tuple elements, but if your list contains dict or other list elements, then you will end up with TypeError exceptions.

Here is a general order-preserving solution to handle some (not all) non-hashable types:

def unique_elements(iterable):
    seen = set()
    result = []
    for element in iterable:
        hashed = element
        if isinstance(element, dict):
            hashed = tuple(sorted(element.iteritems()))
        elif isinstance(element, list):
            hashed = tuple(element)
        if hashed not in seen:
            result.append(element)
            seen.add(hashed)
    return result

Simplest & most correct way is:

from distutils.util import strtobool

parser.add_argument('--feature', dest='feature', 
                    type=lambda x: bool(strtobool(x)))

Do note that True values are y, yes, t, true, on and 1; false values are n, no, f, false, off and 0. Raises ValueError if val is anything else.

Power is ** and e^ is math.exp:

x.append(1 - math.exp(-0.5 * (value1*value2)**2))

I have tried this, write your own code for formWindowClosing() event.

 private void formWindowClosing(java.awt.event.WindowEvent evt) {                                   
    int selectedOption = JOptionPane.showConfirmDialog(null,
            "Do you want to exit?",
            "FrameToClose",
            JOptionPane.YES_NO_OPTION);
    if (selectedOption == JOptionPane.YES_OPTION) {
        setVisible(false);
        dispose();
    } else {
        setDefaultCloseOperation(javax.swing.WindowConstants.DO_NOTHING_ON_CLOSE);
    }
}    

This asks user whether he want to exit the Frame or Application.

You can do by using a custom middleware, even though knowing that the best option is using the tested approach of the package django-cors-headers. With that said, here is the solution:

create the following structure and files:

-- myapp/middleware/__init__.py

from corsMiddleware import corsMiddleware

-- myapp/middleware/corsMiddleware.py

class corsMiddleware(object):
    def process_response(self, req, resp):
        resp["Access-Control-Allow-Origin"] = "*"
        return resp

add to settings.py the marked line:

MIDDLEWARE_CLASSES = (
    "django.contrib.sessions.middleware.SessionMiddleware",
    "django.middleware.common.CommonMiddleware",
    "django.middleware.csrf.CsrfViewMiddleware",

    # Now we add here our custom middleware
     'app_name.middleware.corsMiddleware' <---- this line
)

Firstly, your example is looking quite correct and works well on my machine. You may go another way.

curl $CURLARGS $RVMHTTP > ./install.sh

All output now storing in ./install.sh file, which you can edit and execute.

Presumably, the primary use case for this is to get a base model to the view for all (or the majority of) controller actions.

Given that, I've used a combination of several of these answers, primary piggy backing on Colin Bacon's answer.

It is correct that this is still controller logic because we are populating a viewmodel to return to a view. Thus the correct place to put this is in the controller.

We want this to happen on all controllers because we use this for the layout page. I am using it for partial views that are rendered in the layout page.

We also still want the added benefit of a strongly typed ViewModel

Thus, I have created a BaseViewModel and BaseController. All ViewModels Controllers will inherit from BaseViewModel and BaseController respectively.

The code:

BaseController

public class BaseController : Controller
{
    protected override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        base.OnActionExecuted(filterContext);

        var model = filterContext.Controller.ViewData.Model as BaseViewModel;

        model.AwesomeModelProperty = "Awesome Property Value";
        model.FooterModel = this.getFooterModel();
    }

    protected FooterModel getFooterModel()
    {
        FooterModel model = new FooterModel();
        model.FooterModelProperty = "OMG Becky!!! Another Awesome Property!";
    }
}

Note the use of OnActionExecuted as taken from this SO post

HomeController

public class HomeController : BaseController
{
    public ActionResult Index(string id)
    {
        HomeIndexModel model = new HomeIndexModel();

        // populate HomeIndexModel ...

        return View(model);
    }
}

BaseViewModel

public class BaseViewModel
{
    public string AwesomeModelProperty { get; set; }
    public FooterModel FooterModel { get; set; }
}

HomeViewModel

public class HomeIndexModel : BaseViewModel
{

    public string FirstName { get; set; }

    // other awesome properties
}

FooterModel

public class FooterModel
{
    public string FooterModelProperty { get; set; }
}

Layout.cshtml

@model WebSite.Models.BaseViewModel
<!DOCTYPE html>
<html>
<head>
    < ... meta tags and styles and whatnot ... >
</head>
<body>
    <header>
        @{ Html.RenderPartial("_Nav", Model.FooterModel.FooterModelProperty);}
    </header>

    <main>
        <div class="container">
            @RenderBody()
        </div>

        @{ Html.RenderPartial("_AnotherPartial", Model); }
        @{ Html.RenderPartial("_Contact"); }
    </main>

    <footer>
        @{ Html.RenderPartial("_Footer", Model.FooterModel); }
    </footer>

    < ... render scripts ... >

    @RenderSection("scripts", required: false)
</body>
</html>

_Nav.cshtml

@model string
<nav>
    <ul>
        <li>
            <a href="@Model" target="_blank">Mind Blown!</a>
        </li>
    </ul>
</nav>

Hopefully this helps.

You may want to take a look at Pyschools, the website has quite a lot of practice questions on Python Programming.

Here is a similar question to yours. (Practically the same.)

What ways are there to validate PHP code?

Edit

The top answer there suggest this resource:

http://www.meandeviation.com/tutorials/learnphp/php-syntax-check/v4/syntax-check.php

On the HTTP Response where you are returning the PDF file, ensure the content disposition header looks like:

Content-Disposition: attachment; filename=quot.pdf;

See content-disposition on the wikipedia MIME page.

<?php
    $res = mysql_query('SELECT getTreeNodeName(1) AS result');
    if ($res === false) {
        echo mysql_errno().': '.mysql_error();
    }
    while ($obj = mysql_fetch_object($res)) {
        echo $obj->result;
    }

If you want to just fit the image in image view you can use" wrap content" in height and width property with scale-type but if you want to set manually you have to use LayoutParams.

Layoutparams is efficient for setting the layout height and width programmatically.

This is possible, but you'll have to build it manually from the location object:

location.protocol + '//' + location.host + location.pathname

Yes, you'll need arrays.

var days = ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'];
var months = ['January','February','March','April','May','June','July','August','September','October','November','December'];

var day = days[ now.getDay() ];
var month = months[ now.getMonth() ];

Or you can use the date.js library.

EDIT:

If you're going to use these frequently, you may want to extend Date.prototype for accessibility.

(function() {
    var days = ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'];

    var months = ['January','February','March','April','May','June','July','August','September','October','November','December'];

    Date.prototype.getMonthName = function() {
        return months[ this.getMonth() ];
    };
    Date.prototype.getDayName = function() {
        return days[ this.getDay() ];
    };
})();

var now = new Date();

var day = now.getDayName();
var month = now.getMonthName();

To summarize the responses, extend them, and to answer your question directly:

No, C++ does not impose any limits for the dimensions of an array.

But as the array has to be stored somewhere in memory, so memory-related limits imposed by other parts of the computer system apply. Note that these limits do not directly relate to the dimensions (=number of elements) of the array, but rather to its size (=amount of memory taken). Dimensions (D) and in-memory size (S) of an array is not the same, as they are related by memory taken by a single element (E): S=D * E.

Now E depends on:

• the type of the array elements (elements can be smaller or bigger)
• memory alignment (to increase performance, elements are placed at addresses which are multiplies of some value, which introduces
  ‘wasted space’ (padding) between elements
• size of static parts of objects (in object-oriented programming static components of objects of the same type are only stored once, independent from the number of such same-type objects)

Also note that you generally get different memory-related limitations by allocating the array data on stack (as an automatic variable: int t[N]), or on heap (dynamic alocation with malloc()/new or using STL mechanisms), or in the static part of process memory (as a static variable: static int t[N]). Even when allocating on heap, you still need some tiny amount of memory on stack to store references to the heap-allocated blocks of memory (but this is negligible, usually).

The size of size_t type has no influence on the programmer (I assume programmer uses size_t type for indexing, as it is designed for it), as compiler provider has to typedef it to an integer type big enough to address maximal amount of memory possible for the given platform architecture.

The sources of the memory-size limitations stem from

• amount of memory available to the process (which is limited to 2^32 bytes for 32-bit applications, even on 64-bits OS kernels),
• the division of process memory (e.g. amount of the process memory designed for stack or heap),
• the fragmentation of physical memory (many scattered small free memory fragments are not applicable to storing one monolithic structure),
• amount of physical memory,
• and the amount of virtual memory.

They can not be ‘tweaked’ at the application level, but you are free to use a different compiler (to change stack size limits), or port your application to 64-bits, or port it to another OS, or change the physical/virtual memory configuration of the (virtual? physical?) machine.

It is not uncommon (and even advisable) to treat all the above factors as external disturbances and thus as possible sources of runtime errors, and to carefully check&react to memory-allocation related errors in your program code.

So finally: while C++ does not impose any limits, you still have to check for adverse memory-related conditions when running your code... :-)

Darin Dimitrov's answer shows that OrderBy is slightly faster than List.Sort when faced with already-sorted input. I modified his code so it repeatedly sorts the unsorted data, and OrderBy is in most cases slightly slower.

Furthermore, the OrderBy test uses ToArray to force enumeration of the Linq enumerator, but that obviously returns a type (Person[]) which is different from the input type (List<Person>). I therefore re-ran the test using ToList rather than ToArray and got an even bigger difference:

Sort: 25175ms
OrderBy: 30259ms
OrderByWithToList: 31458ms

Applying the full_extent() function in an answer by @Joe 3 years later from here, you can get exactly what the OP was looking for. Alternatively, you can use Axes.get_tightbbox() which gives a little tighter bounding box

import matplotlib.pyplot as plt
import matplotlib as mpl
import numpy as np
from matplotlib.transforms import Bbox

def full_extent(ax, pad=0.0):
    """Get the full extent of an axes, including axes labels, tick labels, and
    titles."""
    # For text objects, we need to draw the figure first, otherwise the extents
    # are undefined.
    ax.figure.canvas.draw()
    items = ax.get_xticklabels() + ax.get_yticklabels() 
#    items += [ax, ax.title, ax.xaxis.label, ax.yaxis.label]
    items += [ax, ax.title]
    bbox = Bbox.union([item.get_window_extent() for item in items])

    return bbox.expanded(1.0 + pad, 1.0 + pad)

# Make an example plot with two subplots...
fig = plt.figure()
ax1 = fig.add_subplot(2,1,1)
ax1.plot(range(10), 'b-')

ax2 = fig.add_subplot(2,1,2)
ax2.plot(range(20), 'r^')

# Save the full figure...
fig.savefig('full_figure.png')

# Save just the portion _inside_ the second axis's boundaries
extent = full_extent(ax2).transformed(fig.dpi_scale_trans.inverted())
# Alternatively,
# extent = ax.get_tightbbox(fig.canvas.renderer).transformed(fig.dpi_scale_trans.inverted())
fig.savefig('ax2_figure.png', bbox_inches=extent)

I'd post a pic but I lack the reputation points

Hands down the easiest way to parse a HTML table is to use pandas.read_html() - it accepts both URLs and HTML.

import pandas as pd
url = r'https://en.wikipedia.org/wiki/List_of_S%26P_500_companies'
tables = pd.read_html(url) # Returns list of all tables on page
sp500_table = tables[0] # Select table of interest

Only downside is that read_html() doesn't preserve hyperlinks.

JavaScript Object <-> JSON String

JSON.stringify() <-> JSON.parse()

JSON.stringify(obj) - Takes any serializable object and returns the JSON representation as a string.

JSON.stringify() -> Object To String.

JSON.parse(string) - Takes a well formed JSON string and returns the corresponding JavaScript object.

JSON.parse() -> String To Object.

Explanation: JSON.stringify(obj [, replacer [, space]]);

Replacer/Space - optional or takes integer value or you can call interger type return function.

function replacer(key, value) {
    if (typeof value === 'number' && !isFinite(value)) {
        return String(value);
    }
    return value;
}

• Replacer Just Use for replace non finite no with null.
• Space use for indenting Json String by space

This is what a constant expression in Java looks like:

package com.mycompany.mypackage;

public class MyLinks {
  // constant expression
  public static final String GUESTBOOK_URL = "/guestbook";
}

You can use it with annotations as following:

import com.mycompany.mypackage.MyLinks;

@WebServlet(urlPatterns = {MyLinks.GUESTBOOK_URL})
public class GuestbookServlet extends HttpServlet {
  // ...
}

The following code shows how you can use toolhelp and OpenProcess to get a handle to the process. Error handling removed for brevity.

HANDLE GetProcessByName(PCSTR name)
{
    DWORD pid = 0;

    // Create toolhelp snapshot.
    HANDLE snapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
    PROCESSENTRY32 process;
    ZeroMemory(&process, sizeof(process));
    process.dwSize = sizeof(process);

    // Walkthrough all processes.
    if (Process32First(snapshot, &process))
    {
        do
        {
            // Compare process.szExeFile based on format of name, i.e., trim file path
            // trim .exe if necessary, etc.
            if (string(process.szExeFile) == string(name))
            {
               pid = process.th32ProcessID;
               break;
            }
        } while (Process32Next(snapshot, &process));
    }

    CloseHandle(snapshot);

    if (pid != 0)
    {
         return OpenProcess(PROCESS_ALL_ACCESS, FALSE, pid);
    }

    // Not found


       return NULL;
}

You're asking for a comparison between a procedural language and a functional language so I feel your question can be answered here: What is the difference between procedural programming and functional programming?

As to why MS created F# the answer is simply: Creating a functional language with access to the .Net library simply expanded their market base. And seeing how the syntax is nearly identical to OCaml, it really didn't require much effort on their part.

You can read your BufferedInputStream like this. It will read data till it reaches end of stream which is indicated by -1.

inputS = new BufferedInputStream(inBS);
byte[] buffer = new byte[1024];    //If you handle larger data use a bigger buffer size
int read;
while((read = inputS.read(buffer)) != -1) {
    System.out.println(read);
    // Your code to handle the data
}

Take a look at the System log in Windows EventViewer (eventvwr from the command line).
You should see entries with source as 'Service Control Manager'. e.g. on my WinXP machine,

Event Type: Information
Event Source:   Service Control Manager
Event Category: None
Event ID:   7036
Date:       7/1/2009
Time:       12:09:43 PM
User:       N/A
Computer:   MyMachine
Description:
The Background Intelligent Transfer Service service entered the running state.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

simply put this on terminal at ubuntu:

mysql -u username -h host -p

Now hit enter

terminal will ask you password, enter the password and you are into database server

You can set the line height on the text, for example within the active class:

.active {
    ...
    line-height: 2em;
    ....
}

I feel the simplest way would be

 from matplotlib import pyplot;
 from pylab import genfromtxt;  
 mat0 = genfromtxt("data0.txt");
 mat1 = genfromtxt("data1.txt");
 pyplot.plot(mat0[:,0], mat0[:,1], label = "data0");
 pyplot.plot(mat1[:,0], mat1[:,1], label = "data1");
 pyplot.legend();
 pyplot.show();

1. label is the string that is displayed on the legend
2. you can plot as many series of data points as possible before show() to plot all of them on the same graph This is the simple way to plot simple graphs. For other options in genfromtxt go to this url.

On Amazon RDS FLUSH HOSTS; can be executed from default user ("Master Username" in RDS info), and it helps.

In angular 4, this worked for me

template.html

<select (change)="filterChanged($event.target.value)">
  <option *ngFor="let type of filterTypes" [value]="type.value">{{type.display}}
  </option>
</select>

component.ts

export class FilterComponent implements OnInit {

selectedFilter:string;
   public filterTypes = [
     { value: 'percentage', display: 'percentage' },
     { value: 'amount', display: 'amount' }
  ];

   constructor() { 
     this.selectedFilter = 'percentage';
   }

   filterChanged(selectedValue:string){
     console.log('value is ', selectedValue);
   }

  ngOnInit() {
  }
}

You can do it using setOnKeyListener or using a textWatcher like:

Set text watcher editText.addTextChangedListener(textWatcher);

then call

private TextWatcher textWatcher = new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            //after text changed
        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count,
                int after) {
        }

        @Override
        public void afterTextChanged(Editable s) {

        }
    };

If you want a one-liner, you can do:

df.rename(columns=df.iloc[0]).drop(df.index[0])

I'm not sure of your exact requirement but one possible solution to improve 'readability' is to store it as an array.

{
  "testCases" :
  {
    "case.1" :
    {
      "scenario" : "this the case 1.",
      "result" : ["this is a very long line which is not easily readble.",
                  "so i would like to write it in multiple lines.",
                  "but, i do NOT require any new lines in the output."]
    }
  }
}

}

The join in back again whenever required with

result.join(" ")

You can try using blockinfile instead.

You can do something like

- blockinfile: |
    dest=/etc/network/interfaces backup=yes
    content="iface eth0 inet static
        address 192.168.0.1
        netmask 255.255.255.0"

isEmptyOrSpaces(str){
    return !str || str.trim() === '';
}

If you ever need to transfer the zipped content via network or store it as text, you have to use Base64 encoder(such as apache commons codec Base64) to convert the byte array to a Base64 String, and decode the string back to byte array at remote client. Found an example at Use Zip Stream and Base64 Encoder to Compress Large String Data!

Break up the string into two pieces 

alert ("Please select file " +
       "to delete");

tv.setTextColor(getResources().getColor(R.color.solid_red));

What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.

I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)

Removing Containers

1. To remove a specific container

   docker rm CONTAINER_ID CONTAINER_ID
   

   • For single image

     docker rm  70c0e19168cf
     

   • For multiple images

     docker rm  70c0e19168cf c2ce80b62174
     

2. Remove exited containers

   docker ps -a -f status=exited
   

3. Remove all the containers

   docker ps -q -a | xargs docker rm
   

Removing Images

docker rmi IMAGE_ID

1. Remove specific images

   • for single image

     docker rmi ubuntu
     

   • for multiple images

     docker rmi ubuntu alpine
     

2. Remove dangling images
   Dangling images are layers that have no relationship to any tagged images as the Docker images are constituted of multiple images.

   docker rmi -f $(docker images -f dangling=true -q)
   

3. Remove all Docker images

   docker rmi -f $(docker images -a -q)
   

Removing Volumes

To list volumes, run docker volume ls

1. Remove a specific volume

   docker volume rm VOLUME_NAME
   

2. Remove dangling volumes

   docker volume rm $(docker volume ls -f dangling=true -q)
   

3. Remove a container and its volumes

   docker rm -v CONTAINER_NAME
   

In the Notifications case, the NotificationCompat.Builder uses Builder Pattern

like,

mBuilder = new NotificationCompat.Builder(this)
                    .setSmallIcon(R.drawable.ic_stat_notification)
                    .setContentTitle(getString(R.string.notification))
                    .setContentText(getString(R.string.ping))
                    .setDefaults(Notification.DEFAULT_ALL);

Also you are trying to set value2 using Set keyword, which is not required. You can directly use rng.value2 = 1

below test code for ref.

Sub test()
    Dim rng As Range
    Set rng = Range("A1")
    rng.Value2 = 1
End Sub

I confess to not having read the whole thread. However when I faced a similar issue I found that checking carefully the case of the file name and correcting that in the HTML reference fixed a similar issue. So local preview on Windows worked but when I published to my server (hosted Linux) I had to make sure "mugshot.jpg" was changed to "mugshot.JPG". Part of the problem is the defaults in Windows hiding full file names behind file type indications.

In my specific case I tried to create a React Native app using the react-native init installation process, when I encountered the discussed problem.

FAILURE: Build failed with an exception.

* What went wrong:

A problem occurred configuring project ':app'.
> SDK location not found. Define location with an ANDROID_SDK_ROOT environment variable or by setting the sdk.dir path in your project's local properties file at 'C:\Users\***\android\local.properties'.

I add this, because when developing an android app using react native, the 'root directory' to which so many answers refer, is actually the root of the android folder (and not the project's root folder, where App.js resides). This is also made clear by the directory marked in the error message.

To solve it, just add a local.properties file to the android folder, and type:

sdk.dir=C:/Users/{user name}/AppData/Local/Android/Sdk

Be sure to add the local disk's reference ('C:/'), because it did not work otherwise in my case.

Cast one of the integers/both of the integer to float to force the operation to be done with floating point Math. Otherwise integer Math is always preferred. So:

1. double d = (double)5 / 20;
2. double v = (double)5 / (double) 20;
3. double v = 5 / (double) 20;

Note that casting the result won't do it. Because first division is done as per precedence rule.

double d = (double)(5 / 20); //produces 0.0

I do not think there is any problem with casting as such you are thinking about.

Here you have not specified class name to be imported from Map.js file. If Map is class exportable class name exist in the Map.js file, your code should be as follow.

import React, { Component } from 'react';
import Map from  './Map';
class App extends Component {
   render() {
     return (
         <div className="App">
            <Map/>
         </div>
     );
   }
}
export default App;

Something like this

 string find = "item_manuf_id = 'some value'";
 DataRow[] foundRows = table.Select(find);

After reading several of these answers, I used a combination of several in Aug of 2018 to retrieve the query string params through lambda for python 3.6.

First, I went to API Gateway -> My API -> resources (on the left) -> Integration Request. Down at the bottom, select Mapping Templates then for content type enter application/json.

Next, select the Method Request Passthrough template that Amazon provides and select save and deploy your API.

Then in, lambda event['params'] is how you access all of your parameters. For query string: event['params']['querystring']

useState is a hook that lets you add state to a functional component. It accepts an argument which is the initial value of the state property and returns the current value of state property and a method which is capable of updating that state property.
Following is a simple example:

import React, {useState} from react    

function HookCounter {    
  const [count, stateCount]= useState(0)    
    return(    
      <div>     
        <button onClick{( ) => setCount(count+1)}> count{count}</button>    
      </div>    
    )   
 }

useState accepts the initial value of the state variable which is zero in this case and returns a pair of values. The current value of the state has been called count and a method that can update the state variable has been called as setCount.

First you can write the code:

{    [self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];}

after that

{    #define cellHeight 80 // You can change according to your req.<br>
     #define cellWidth 320 // You can change according to your req.<br>

    -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath  *)indexPath
    {
         UIImageView *imgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"seprater_line.png"]];
        imgView.frame = CGRectMake(0, cellHeight, cellWidth, 1);
        [customCell.contentView addSubview:imgView];
         return  customCell;

     }
}

ah homework...

So wait, you need to deduct the balance of items in stock from the total number of those items that have been ordered? I have to tell you that sounds a bit backwards. Generally I think people do it the other way round. Deduct the total number of items ordered from the balance.

If you really need to do that though... Assuming that ITEM is unique in stock_bal...

SELECT s.ITEM, SUM(m.QTY) - s.QTY AS result
FROM stock_bal s
INNER JOIN master_table m ON m.ITEM = s.ITEM
GROUP BY s.ITEM, s.QTY

You can still use EditorFor. Just pass the style/whichever html attribute as ViewData.

@Html.EditorFor(model => model.YourProperty, new { style = "Width:50px" })

Because EditorFor uses templates to render, you could override the default template for your property and simply pass the style attribute as ViewData.

So your EditorTemplate would like the following:

@inherits System.Web.Mvc.WebViewPage<object>

@Html.TextBoxFor(m => m, new { @class = "text ui-widget-content", style=ViewData["style"] })

python setup.py install is used to install (typically third party) packages that you're not going to develop/modify/debug yourself.

For your own stuff, you want to first install your package and then be able to frequently edit the code without having to re-install the package every time — and that is exactly what python setup.py develop does: it installs the package (typically just a source folder) in a way that allows you to conveniently edit your code after it’s installed to the (virtual) environment, and have the changes take effect immediately.

Note that it is highly recommended to use pip install . (install) and pip install -e . (developer install) to install packages, as invoking setup.py directly will do the wrong things for many dependencies, such as pull prereleases and incompatible package versions, or make the package hard to uninstall with pip.

One possible solution can be

class Survey{
  void renderSurvey(Question q) {
  /*
      Depending on the type of question (choice, dropdwn or other, I have to render
      the question on the UI. The class that calls this doesnt have compile time 
      knowledge of the type of question that is going to be rendered. Each question 
      type has its own rendering function. If this is for choice , I need to access 
      its functions using q. 
  */
  if(q.getOption() instanceof ChoiceQuestionOption)
  {
    ChoiceQuestionOption choiceQuestion = (ChoiceQuestionOption)q.getOption();
    boolean result = choiceQuestion.getMultiple();
    //do something with result......
  }
 }
}

Use android:textStyle="bold"

4 ways to make Android TextView Bold

like this

<TextView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:textSize="12dip"
android:textStyle="bold"
/>

There are many ways to make Android TextView bold.

Just to continue to all the answers that were given here, especially @James Lanes

the size of the integer type can be expressed by this formula:

total range = (2 ^ bit system)

lower limit = -(2 ^ bit system)*0.5 upper limit = ((2 ^ bit system)*0.5) - 1

You can find more methods and functions related to Python strings in section 5.6.1. String Methods of the documentation.

w.strip(',.').lower()

Slightly longer version, but if you have to use pure Bash for some reason, you can use a while loop with an incrementing variable:

n=0; while [ $n -lt 100 ]; do n=$((n+1)); echo -n '='; done

Check whether your config string is okay:

Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9999

I just had this issue today, and in my case it was because there was an invisible character in the jpda config parameter.

To be precise, I had dos line endings in my setenv.sh file on tomcat, causing a carriage-return character right after 'dt_socket'

Javascript's String.fromCharCode(code1, code2, ..., codeN) takes an infinite number of arguments and returns a string of letters whose corresponding ASCII values are code1, code2, ... codeN. Since 97 is 'a' in ASCII, we can adjust for your indexing by adding 97 to your index.

function indexToChar(i) {
  return String.fromCharCode(i+97); //97 in ASCII is 'a', so i=0 returns 'a', 
                                    // i=1 returns 'b', etc
}

resize() not only allocates memory, it also creates as many instances as the desired size which you pass to resize() as argument. But reserve() only allocates memory, it doesn't create instances. That is,

std::vector<int> v1;
v1.resize(1000); //allocation + instance creation
cout <<(v1.size() == 1000)<< endl;   //prints 1
cout <<(v1.capacity()==1000)<< endl; //prints 1

std::vector<int> v2;
v2.reserve(1000); //only allocation
cout <<(v2.size() == 1000)<< endl;   //prints 0
cout <<(v2.capacity()==1000)<< endl; //prints 1

Output (online demo):

1
1
0
1

So resize() may not be desirable, if you don't want the default-created objects. It will be slow as well. Besides, if you push_back() new elements to it, the size() of the vector will further increase by allocating new memory (which also means moving the existing elements to the newly allocated memory space). If you have used reserve() at the start to ensure there is already enough allocated memory, the size() of the vector will increase when you push_back() to it, but it will not allocate new memory again until it runs out of the space you reserved for it.

Some of the code I see in here fails with years like 2016, in which week 53 jumps to week 2.

Here is a revised and working version:

Date.prototype.getWeek = function() { 

  // Create a copy of this date object  
  var target  = new Date(this.valueOf());  

  // ISO week date weeks start on monday, so correct the day number  
  var dayNr   = (this.getDay() + 6) % 7;  

  // Set the target to the thursday of this week so the  
  // target date is in the right year  
  target.setDate(target.getDate() - dayNr + 3);  

  // ISO 8601 states that week 1 is the week with january 4th in it  
  var jan4    = new Date(target.getFullYear(), 0, 4);  

  // Number of days between target date and january 4th  
  var dayDiff = (target - jan4) / 86400000;    

  if(new Date(target.getFullYear(), 0, 1).getDay() < 5) {
    // Calculate week number: Week 1 (january 4th) plus the    
    // number of weeks between target date and january 4th    
    return 1 + Math.ceil(dayDiff / 7);    
  }
  else {  // jan 4th is on the next week (so next week is week 1)
    return Math.ceil(dayDiff / 7); 
  }
}; 

I have http_proxy and https_proxy are defined. I don't want to unset and set again those environments but --noproxy '*' works perfectly for me.

curl --noproxy '*' -XGET 172.17.0.2:9200
{
  "status" : 200,
  "name" : "Medusa",
  "cluster_name" : "elasticsearch",
  "version" : {
    "number" : "1.5.0",
    "build_hash" : "544816042d40151d3ce4ba4f95399d7860dc2e92",
    "build_timestamp" : "2015-03-23T14:30:58Z",
    "build_snapshot" : false,
    "lucene_version" : "4.10.4"
  },
  "tagline" : "You Know, for Search"
}

First argument in update method is SyntheticEvent object that contains common properties and methods to any event, it is not reference to React component where there is property props.

if you need pass argument to update method you can do it like this

onClick={ (e) => this.props.onClick(e, 'home', 'Home') }

and get these arguments inside update method

update(e, space, txt){
   console.log(e.target, space, txt);
}

Example

event.target gives you the native DOMNode, then you need to use the regular DOM APIs to access attributes. For instance getAttribute or dataset

<button 
  data-space="home" 
  className="home" 
  data-txt="Home" 
  onClick={ this.props.onClick } 
/> 
  Button
</button>

onClick(e) {
   console.log(e.target.dataset.txt, e.target.dataset.space);
}

Example
