You can do this easier.

It helped me.

Layout:

<ProgressBar
   android:id="@+id/progressBar1"
   style="?android:attr/progressBarStyleLarge"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:layout_centerHorizontal="true" />

After defining it in xml, you have to get its reference in java file through ProgressBar class. Its syntax is given below:

private ProgressBar spinner;
spinner = (ProgressBar)findViewById(R.id.progressBar1);

After that you can make its disappear , and bring it back when needed through setVisibility Method. Its syntax is given below:

spinner.setVisibility(View.GONE);
spinner.setVisibility(View.VISIBLE);

First the CSS - tweak this however you like:

a.selected {
  background-color:#1F75CC;
  color:white;
  z-index:100;
}

.messagepop {
  background-color:#FFFFFF;
  border:1px solid #999999;
  cursor:default;
  display:none;
  margin-top: 15px;
  position:absolute;
  text-align:left;
  width:394px;
  z-index:50;
  padding: 25px 25px 20px;
}

label {
  display: block;
  margin-bottom: 3px;
  padding-left: 15px;
  text-indent: -15px;
}

.messagepop p, .messagepop.div {
  border-bottom: 1px solid #EFEFEF;
  margin: 8px 0;
  padding-bottom: 8px;
}

And the JavaScript:

function deselect(e) {
  $('.pop').slideFadeToggle(function() {
    e.removeClass('selected');
  });    
}

$(function() {
  $('#contact').on('click', function() {
    if($(this).hasClass('selected')) {
      deselect($(this));               
    } else {
      $(this).addClass('selected');
      $('.pop').slideFadeToggle();
    }
    return false;
  });

  $('.close').on('click', function() {
    deselect($('#contact'));
    return false;
  });
});

$.fn.slideFadeToggle = function(easing, callback) {
  return this.animate({ opacity: 'toggle', height: 'toggle' }, 'fast', easing, callback);
};

And finally the html:

<div class="messagepop pop">
  <form method="post" id="new_message" action="/messages">
    <p><label for="email">Your email or name</label><input type="text" size="30" name="email" id="email" /></p>
    <p><label for="body">Message</label><textarea rows="6" name="body" id="body" cols="35"></textarea></p>
    <p><input type="submit" value="Send Message" name="commit" id="message_submit"/> or <a class="close" href="/">Cancel</a></p>
  </form>
</div>

<a href="/contact" id="contact">Contact Us</a>

Here is a jsfiddle demo and implementation.

Depending on the situation you may want to load the popup content via an ajax call. It's best to avoid this if possible as it may give the user a more significant delay before seeing the content. Here couple changes that you'll want to make if you take this approach.

HTML becomes:

<div>
    <div class="messagepop pop"></div> 
    <a href="/contact" id="contact">Contact Us</a>
</div>

And the general idea of the JavaScript becomes:

$("#contact").on('click', function() {
    if($(this).hasClass("selected")) {
        deselect();               
    } else {
        $(this).addClass("selected");
        $.get(this.href, function(data) {
            $(".pop").html(data).slideFadeToggle(function() { 
                $("input[type=text]:first").focus();
            });
        }
    }
    return false;
});

First of all, you don't convert a DateTime object to some format, you display it in some format.

Given an instance of a DateTime object, you can get a formatted string in that way like this:

DateTime date = new DateTime(2011, 2, 19);
string formatted = date.ToString("dd/M/yyyy");

JonH has covered very well the part on how to write the query. There is another significant issue that must be mentioned too, however, which is the performance characteristics of such a query. Let's repeat it here (adapted to Oracle):

SELECT EmployeeName FROM EmployeeTable WHERE LENGTH(EmployeeName) > 4;

This query is restricting the result of a function applied to a column value (the result of applying the LENGTH function to the EmployeeName column). In Oracle, and probably in all other RDBMSs, this means that a regular index on EmployeeName will be useless to answer this query; the database will do a full table scan, which can be really costly.

However, various databases offer a function indexes feature that is designed to speed up queries like this. For example, in Oracle, you can create an index like this:

CREATE INDEX EmployeeTable_EmployeeName_Length ON EmployeeTable(LENGTH(EmployeeName));

This might still not help in your case, however, because the index might not be very selective for your condition. By this I mean the following: you're asking for rows where the name's length is more than 4. Let's assume that 80% of the employee names in that table are longer than 4. Well, then the database is likely going to conclude (correctly) that it's not worth using the index, because it's probably going to have to read most of the blocks in the table anyway.

However, if you changed the query to say LENGTH(EmployeeName) <= 4, or LENGTH(EmployeeName) > 35, assuming that very few employees have names with fewer than 5 character or more than 35, then the index would get picked and improve performance.

Anyway, in short: beware of the performance characteristics of queries like the one you're trying to write.

I implemented very fast Postgresq data loader with native libpq methods. Try my package https://www.nuget.org/packages/NpgsqlBulkCopy/

I just ran into this problem; the issue seems different from the other answers posted here, so I'll mention it in case it helps someone.

In my case, I have an internal base class defined in one assembly ("A"), an internal derived class defined in a second assembly ("B"), and a test assembly ("TEST"). I exposed internals defined in assembly "B" to "TEST" using InternalsVisibleToAttribute, but neglected to do so for assembly "A". This produced the error mentioned at top with no further indication of the problem; using InternalsVisibleToAttribute to expose assembly "A" to "TEST" resolved the issue.

The similar problem occurs in aspdotnet core with the same error The program '[xxxx] iisexpress.exe' has exited with code -1073741816 (0xc0000008).

Log file setup in web.config did not produce any info also:

<aspNetCore  stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" />

To find exact error the next step with log info in command prompt helped:

> dotnet restore
> dotnet run

In my case the problem was in dotnet core v 1.0.0 installed, while version 1.0.1 was required to be globally installed.

Justin's answer is awesome and this response goes into more depth.

The repartition algorithm does a full shuffle and creates new partitions with data that's distributed evenly. Let's create a DataFrame with the numbers from 1 to 12.

val x = (1 to 12).toList
val numbersDf = x.toDF("number")

numbersDf contains 4 partitions on my machine.

numbersDf.rdd.partitions.size // => 4

Here is how the data is divided on the partitions:

Partition 00000: 1, 2, 3
Partition 00001: 4, 5, 6
Partition 00002: 7, 8, 9
Partition 00003: 10, 11, 12

Let's do a full-shuffle with the repartition method and get this data on two nodes.

val numbersDfR = numbersDf.repartition(2)

Here is how the numbersDfR data is partitioned on my machine:

Partition A: 1, 3, 4, 6, 7, 9, 10, 12
Partition B: 2, 5, 8, 11

The repartition method makes new partitions and evenly distributes the data in the new partitions (the data distribution is more even for larger data sets).

Difference between coalesce and repartition

coalesce uses existing partitions to minimize the amount of data that's shuffled. repartition creates new partitions and does a full shuffle. coalesce results in partitions with different amounts of data (sometimes partitions that have much different sizes) and repartition results in roughly equal sized partitions.

Is coalesce or repartition faster?

coalesce may run faster than repartition, but unequal sized partitions are generally slower to work with than equal sized partitions. You'll usually need to repartition datasets after filtering a large data set. I've found repartition to be faster overall because Spark is built to work with equal sized partitions.

N.B. I've curiously observed that repartition can increase the size of data on disk. Make sure to run tests when you're using repartition / coalesce on large datasets.

Read this blog post if you'd like even more details.

When you'll use coalesce & repartition in practice

• See this question on how to use coalesce & repartition to write out a DataFrame to a single file
• It's critical to repartition after running filtering queries. The number of partitions does not change after filtering, so if you don't repartition, you'll have way too many memory partitions (the more the filter reduces the dataset size, the bigger the problem). Watch out for the empty partition problem.
• partitionBy is used to write out data in partitions on disk. You'll need to use repartition / coalesce to partition your data in memory properly before using partitionBy.

if (isSet($_SESSION['started'])){
    if((mktime() - $_SESSION['started'] - 60*30) > 0){
        //Logout, destroy session, etc.
    }
}
else {
    $_SESSION['started'] = mktime();
}

In MySQL you can do this...

Trim(Leading '0' from your_column)

this helps for me:

on your build.gradle:

implementation 'com.android.support:design:28.0.0'

To add on to this:

If you're using CMAKE to generate a Visual Studio solution, and you want Visual Studio to output compiled files into /bin, Peter's answer needs to be modified a bit:

# set output directories for all builds (Debug, Release, etc.)
foreach( OUTPUTCONFIG ${CMAKE_CONFIGURATION_TYPES} )
    string( TOUPPER ${OUTPUTCONFIG} OUTPUTCONFIG )
    set( CMAKE_ARCHIVE_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${CMAKE_SOURCE_DIR}/lib )
    set( CMAKE_LIBRARY_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${CMAKE_SOURCE_DIR}/lib )
    set( CMAKE_RUNTIME_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${CMAKE_SOURCE_DIR}/bin )
endforeach( OUTPUTCONFIG CMAKE_CONFIGURATION_TYPES )

try below code:

  >>> d2 = dict([('one',1), ('two', 2), ('three', 3)])
  >>> d2
      {'three': 3, 'two': 2, 'one': 1}

You are setting the response headers after writing the contents of the file to the output stream. This is quite late in the response lifecycle to be setting headers. The correct sequence of operations should be to set the headers first, and then write the contents of the file to the servlet's outputstream.

Therefore, your method should be written as follows (this won't compile as it is a mere representation):

response.setContentType("application/force-download");
response.setContentLength((int)f.length());
        //response.setContentLength(-1);
response.setHeader("Content-Transfer-Encoding", "binary");
response.setHeader("Content-Disposition","attachment; filename=\"" + "xxx\"");//fileName);
...
...
File f= new File(fileName);

InputStream in = new FileInputStream(f);
BufferedInputStream bin = new BufferedInputStream(in);
DataInputStream din = new DataInputStream(bin);

while(din.available() > 0){
    out.print(din.readLine());
    out.print("\n");
}

The reason for the failure is that it is possible for the actual headers sent by the servlet would be different from what you are intending to send. After all, if the servlet container does not know what headers (which appear before the body in the HTTP response), then it may set appropriate headers to ensure that the response is valid; setting the headers after the file has been written is therefore futile and redundant as the container might have already set the headers. You could confirm this by looking at the network traffic using Wireshark or a HTTP debugging proxy like Fiddler or WebScarab.

You may also refer to the Java EE API documentation for ServletResponse.setContentType to understand this behavior:

Sets the content type of the response being sent to the client, if the response has not been committed yet. The given content type may include a character encoding specification, for example, text/html;charset=UTF-8. The response's character encoding is only set from the given content type if this method is called before getWriter is called.

This method may be called repeatedly to change content type and character encoding. This method has no effect if called after the response has been committed.

instead of url: serviceURL, use

url: '<%= serviceURL%>',

and are you passing 2 parameters to successFunc?

function successFunc(data)
 {
   alert(data);
 }

In PySpark, if your dataset is small (can fit into memory of driver), you can do

df.collect()[n]

where df is the DataFrame object, and n is the Row of interest. After getting said Row, you can do row.myColumn or row["myColumn"] to get the contents, as spelled out in the API docs.

Ruby 2.4 has Regexp#match?: (with a ?)

def integer?(str)
  /\A[+-]?\d+\z/.match? str
end

For older Ruby versions, there's Regexp#===. And although direct use of the case equality operator should generally be avoided, it looks very clean here:

def integer?(str)
  /\A[+-]?\d+\z/ === str
end

integer? "123"    # true
integer? "-123"   # true
integer? "+123"   # true

integer? "a123"   # false
integer? "123b"   # false
integer? "1\n2"   # false

Best practice I think is to set the font to the body:

body {
    font: normal 10px Verdana, Arial, sans-serif;
}

and if you decide to change it for some element it could be easily overwrited:

h2, h3 {
    font-size: 14px;
}

You need to Open the output file for write access rather than using a new StreamReader, which always overwrites the output file.

StreamWriter stm = null;
fi = new FileInfo(@"C:\target.xml");
if (fi.Exists)
   stm = fi.OpenWrite();

Of course, you will still have to seek to the correct line in the output file, which will be hard since you can't read from it, so unless you already KNOW the byte offset to seek to, you probably really want read/write access.

FileStream stm = fi.Open(FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.None);

with this stream, you can read until you get to the point where you want to make changes, then write. Keep in mind that you are writing bytes, not lines, so to overwrite a line you will need to write the same number of characters as the line you want to change.

You can define first the width of the element as 0, floating right, and then on the event that you are about to show it.. it would be like

$('#the_element_to_slide_from_right_left').animate({ width:'your desired width' }, 600);

Simple as that.

For internal gridlines, use the tag: td For external gridlines, use the tag: table

You can use as many joins as you want, however, the more you use the more it will impact performance

If you are talking about <input type=button>, it won't automatically submit the form

if you are talking about the <button> tag, that's newer and doesn't automatically submit in all browsers.

Bottom line, if you want the form to submit on click in all browsers, use <input type="submit">

The below answer is in reference to the latest ng-bootstrap

Install

npm install --save @ng-bootstrap/ng-bootstrap

app.module.ts

import {NgbModule} from '@ng-bootstrap/ng-bootstrap';

@NgModule({

export class AppModule { }

Component Controller

import { TemplateRef, ViewChild } from '@angular/core';
import { NgbModal } from '@ng-bootstrap/ng-bootstrap';

@Component({
  selector: 'app-app-registration',
  templateUrl: './app-registration.component.html',
  styleUrls: ['./app-registration.component.css']
})

export class AppRegistrationComponent implements OnInit {

  @ViewChild('editModal') editModal : TemplateRef<any>; // Note: TemplateRef

  constructor(private modalService: NgbModal) { }

  openModal(){
    this.modalService.open(this.editModal);

You can also use the tab character '\t' to represent a tab, instead of "\t".

char c ='t';
char c =(char)9;

any('abc' in item for item in mylist)

defaultMember already is an alias - it doesn't need to be the name of the exported function/thing. Just do

import alias from 'my-module';

Alternatively you can do

import {default as alias} from 'my-module';

but that's rather esoteric.

If you develop in Visual Studio 2013 and 2015 versions, you can use their GPU Usage tool:

• GPU Usage Tool in Visual Studio (video) https://www.youtube.com/watch?v=Gjc5bPXGkTE
• GPU Usage Visual Studio 2015 https://msdn.microsoft.com/en-us/library/mt126195.aspx
• GPU Usage tool in Visual Studio 2013 Update 4 CTP1 (blog) http://blogs.msdn.com/b/vcblog/archive/2014/09/05/gpu-usage-tool-in-visual-studio-2013-update-4-ctp1.aspx
• GPU Usage for DirectX in Visual Studio (blog) http://blogs.msdn.com/b/ianhu/archive/2014/12/16/gpu-usage-for-directx-in-visual-studio.aspx

Screenshot from MSDN:

Moreover, it seems you can diagnose any application with it, not only Visual Studio Projects:

In addition to Visual Studio projects you can also collect GPU usage data on any loose .exe applications that you have sitting around. Just open the executable as a solution in Visual Studio and then start up a diagnostics session and you can target it with GPU usage. This way if you are using some type of engine or alternative development environment you can still collect data on it as long as you end up with an executable.

Try to create remote origin first, maybe is missing because you change name of the remote repo

git remote add origin URL_TO_YOUR_REPO

In short, yes. I assume you're looking to parse English: for that you can use the Link Parser from Carnegie Mellon.

It is important to remember that there are many theories of syntax, that can give completely different-looking phrase structure trees; further, the trees are different for each language, and tools may not exist for those languages.

As a note for the future: if you need a sentence parsed out and tag it as linguistics (and syntax or whatnot, if that's available), someone can probably parse it out for you and guide you through it.

You can use below code on onSuccess(LoginResult loginResult)

loginResult.getAccessToken().getUserId();

Create an new Style with any name, in my case "Theme.Alert.NoActionBar"

<style name="Theme.Alert.NoActionBar" parent="Theme.AppCompat.Dialog">
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
</style>

set its parent as "Theme.AppCompat.Dialog" like in the above code

open AndoridManifest.xml and customize the activity you want to show as Alert Dialog like this

    <activity
        android:excludeFromRecents="true"
        android:theme="@style/Theme.Alert.NoActionBar"
        android:name=".activities.UserLoginActivity" />

in my app i want show my user login activity as Alert Dialog, these are the codes i used. hope this works for you!!!

user1  = pd.read_csv('dataset/1.csv',  names=['Time',  'X',  'Y',  'Z']) 

names parameter in read_csv function is used to define column names. If you pass extra name in this list, it will add another new column with that name with NaN values.

header=None is used to trim column names is already exists in CSV file.

Deletion of a topic has been supported since 0.8.2.x version. You have to enable topic deletion (setting delete.topic.enable to true) on all brokers first.

Note: Ever since 1.0.x, the functionality being stable, delete.topic.enable is by default true.

Follow this step by step process for manual deletion of topics

1. Stop Kafka server
2. Delete the topic directory, on each broker (as defined in the logs.dirs and log.dir properties) with rm -rf command
3. Connect to Zookeeper instance: zookeeper-shell.sh host:port
4. From within the Zookeeper instance:
   1. List the topics using: ls /brokers/topics
   2. Remove the topic folder from ZooKeeper using: rmr /brokers/topics/yourtopic
   3. Exit the Zookeeper instance (Ctrl+C)
5. Restart Kafka server
6. Confirm if it was deleted or not by using this command kafka-topics.sh --list --zookeeper host:port

This works for me. Hope it will work for you too.

I think the author probably meant:

if Verbose:
   print("Building internam Index for %d tile(s) ..." % len(inputTiles), end=' ')

He's missing an initial quote after print(.

Note that as of Python 3.0, print is a function as opposed to a statement, if you're using older versions of Python the equivalent would be:

print "Building internam Index for %d tile(s) ..." % len(inputTiles)

The end parameter means that the line gets ' ' at the end rather than a newline character. The equivalent in earlier versions of Python is:

print "Building internam Index for %d tile(s) ..." % len(inputTiles),

i think its helpfull to you

                JSONArray jre = objJson.getJSONArray("Result");

                for (int j = 0; j < jre.length(); j++) {
                    JSONObject jobject = jre.getJSONObject(j);

                    String  date = jobject.getString("Date");
                    String  keywords=jobject.getString("keywords");
                    String  needed=jobject.getString("NeededString");

                }

I would suggest that you just write the case statement yourself using datename():

select (case datename(dw, aws.date)
             when 'Monday' then 1
             when 'Tuesday' then 2
             when 'Wednesday' then 3
             when 'Thursday' then 4
             when 'Friday' then 5
             when 'Saturday' then 6
             when 'Sunday' then 7
        end)

At least, this won't change if someone changes the parameter on the day of the week when weeks begin. On the other hand, it is susceptible to the language chosen for SQL Server.

        document.getElementById("txturl").value = '';
    } else {
        alert("Please enter valid URL..!");
        return false;
    }
}

I have also created a bin with the solution on http://codebins.com/codes/home/4ldqpbw

ngStyle accepts a map:

$scope.myStyle = {
    "width" : "900px",
    "background" : "red"
};

Fiddle

This is my case: it's run Environment: AspNet Core 2.1 Controller:

public class MyController
{
    // ...

    [HttpPost]
    public ViewResult Search([FromForm]MySearchModel searchModel)
    {
        // ...
        return View("Index", viewmodel);
    }
}

View:

<form method="post" asp-controller="MyController" asp-action="Search">
    <input name="MySearchModelProperty" id="MySearchModelProperty" />
    <input type="submit" value="Search" />
</form>

Shift-tab doesn't seem to work on multi-lines in Aptana. It also doesn't work on single lines with a single preceding space. Any workarounds? I use shift-tab (outdent) to fix badly formatted code all the time.

I miss NetBeans ...

UPDATE: it works on multi-newlines, if the multi-lines have the same level of indentation. It should just continue outdenting the other lines that haven't reached the beginning of the new line yet. Is there an option to change this I wonder?

When you push to a remote and you use the --set-upstream flag git sets the branch you are pushing to as the remote tracking branch of the branch you are pushing.

Adding a remote tracking branch means that git then knows what you want to do when you git fetch, git pull or git push in future. It assumes that you want to keep the local branch and the remote branch it is tracking in sync and does the appropriate thing to achieve this.

You could achieve the same thing with git branch --set-upstream-to or git checkout --track. See the git help pages on tracking branches for more information.

To get value, use:

$.each($('input'),function(i,val){
    if($(this).attr("type")=="hidden"){
        var valueOfHidFiled=$(this).val();
        alert(valueOfHidFiled);
    }
});

or:

var valueOfHidFiled=$('input[type=hidden]').val();
alert(valueOfHidFiled);

To set value, use:

$('input[type=hidden]').attr('value',newValue);

On your solution explorer window, right click to References, select Add Reference, go to .NET tab, find and add Microsoft.CSharp.

Alternatively add the Microsoft.CSharp NuGet package.

Install-Package Microsoft.CSharp

You just need to initialize your NSMutableArray

NSMutableArray  *myArray = [[NSMutableArray alloc] init];

To fix the indentation and formatting in all files of your solution:

1. Install the Format All Files extension => close VS, execute the .vsix file and reopen VS;
2. Menu Tools > Options... > Text Editor > All Languages > Tabs:
   1. Click on Smart (for resolving conflicts);
   2. Type the Tab Size and Indent Size you want (e.g. 2);
   3. Click on Insert Spaces if you want to replace tabs by spaces;
3. In the Solution Explorer (Ctrl+Alt+L) right click in any file and choose from the menu Format All Files (near the bottom).

This will recursively open and save all files in your solution, setting the indentation you defined above.

You might want to check other programming languages tabs (Options...) for Code Style > Formatting as well.

The answer is this revoke your Current Development Certificate and make a new one. follow the instructions on apples site on how to do so. Its that simple!! I had this exact problem.

In a regular expression, you can "capture" parts of the matched string with (brackets); in this case, you are capturing the (^|_) and ([a-z]) parts of the match. These are numbered starting at 1, so you have back-references 1 and 2. Match 0 is the whole matched string.

The /e modifier takes a replacement string, and substitutes backslash followed by a number (e.g. \1) with the appropriate back-reference - but because you're inside a string, you need to escape the backslash, so you get '\\1'. It then (effectively) runs eval to run the resulting string as though it was PHP code (which is why it's being deprecated, because it's easy to use eval in an insecure way).

The preg_replace_callback function instead takes a callback function and passes it an array containing the matched back-references. So where you would have written '\\1', you instead access element 1 of that parameter - e.g. if you have an anonymous function of the form function($matches) { ... }, the first back-reference is $matches[1] inside that function.

So a /e argument of

'do_stuff(\\1) . "and" . do_stuff(\\2)'

could become a callback of

function($m) { return do_stuff($m[1]) . "and" . do_stuff($m[2]); }

Or in your case

'strtoupper("\\2")'

could become

function($m) { return strtoupper($m[2]); }

Note that $m and $matches are not magic names, they're just the parameter name I gave when declaring my callback functions. Also, you don't have to pass an anonymous function, it could be a function name as a string, or something of the form array($object, $method), as with any callback in PHP, e.g.

function stuffy_callback($things) {
    return do_stuff($things[1]) . "and" . do_stuff($things[2]);
}
$foo = preg_replace_callback('/([a-z]+) and ([a-z]+)/', 'stuffy_callback', 'fish and chips');

As with any function, you can't access variables outside your callback (from the surrounding scope) by default. When using an anonymous function, you can use the use keyword to import the variables you need to access, as discussed in the PHP manual. e.g. if the old argument was

'do_stuff(\\1, $foo)'

then the new callback might look like

function($m) use ($foo) { return do_stuff($m[1], $foo); }

Gotchas

• Use of preg_replace_callback is instead of the /e modifier on the regex, so you need to remove that flag from your "pattern" argument. So a pattern like /blah(.*)blah/mei would become /blah(.*)blah/mi.
• The /e modifier used a variant of addslashes() internally on the arguments, so some replacements used stripslashes() to remove it; in most cases, you probably want to remove the call to stripslashes from your new callback.

Try to keep all constant at one place, In my application I have created constants folder inside initializers as follows:

and I usually keep all constant in these files.

In your case you can create file under constants folder as colors_constant.rb

colors_constant.rb

Don't forgot to restart server

I wrote a wrapper component that can be reused for this purpose that builds on the accepted answers here. If all you need to do is pass a string however, then just add a data-attribute and read it from e.target.dataset (like some others have suggested). By default my wrapper will bind to any prop that is a function and starts with 'on' and automatically pass the data prop back to the caller after all the other event arguments. Although I haven't tested it for performance, it will give you the opportunity to avoid creating the class yourself, and it can be used like this:

const DataButton = withData('button')
const DataInput = withData('input');

or for Components and functions

const DataInput = withData(SomeComponent);

or if you prefer

const DataButton = withData(<button/>)

declare that Outside your container (near your imports)

Here is usage in a container:

import withData from './withData';
const DataInput = withData('input');

export default class Container extends Component {
    state = {
         data: [
             // ...
         ]
    }

    handleItemChange = (e, data) => {
        // here the data is available 
        // ....
    }

    render () {
        return (
            <div>
                {
                    this.state.data.map((item, index) => (
                        <div key={index}>
                            <DataInput data={item} onChange={this.handleItemChange} value={item.value}/>
                        </div>
                    ))
                }
            </div>
        );
    }
}

Here is the wrapper code 'withData.js:

import React, { Component } from 'react';

const defaultOptions = {
    events: undefined,
}

export default (Target, options) => {
    Target = React.isValidElement(Target) ? Target.type : Target;
    options = { ...defaultOptions, ...options }

    class WithData extends Component {
        constructor(props, context){
            super(props, context);
            this.handlers = getHandlers(options.events, this);        
        }

        render() {
            const { data, children, ...props } = this.props;
            return <Target {...props} {...this.handlers} >{children}</Target>;
        }

        static displayName = `withData(${Target.displayName || Target.name || 'Component'})`
    }

    return WithData;
}

function getHandlers(events, thisContext) {
    if(!events)
        events = Object.keys(thisContext.props).filter(prop => prop.startsWith('on') && typeof thisContext.props[prop] === 'function')
    else if (typeof events === 'string')
        events = [events];

    return events.reduce((result, eventType) => {
        result[eventType] = (...args) => thisContext.props[eventType](...args, thisContext.props.data);
        return result;
    }, {});
}

There is actually an example for this type of issue in the Ant documentation. It makes use of Selectors (mentioned above) and mappers. See last example in http://ant.apache.org/manual/Types/dirset.html :

<dirset id="dirset" dir="${workingdir}">
   <present targetdir="${workingdir}">
        <mapper type="glob" from="*" to="*/${markerfile}" />
   </present>
</dirset>

Selects all directories somewhere under ${workingdir} which contain a ${markerfile}.

can use it too

                      "height": h
                     ,"width": w
                };
                return size;
            }

Instruction from AWS EC2 support:

1. Change pem login
2. go to your EC2 Console
3. Under NETWORK & SECURITY, click on Key Pair Click on Create Key Pair
4. Give your new key pair a name, save the .pem file. The name of the key pair will be used to connect to your instance
5. Create SSH connection to your instance and keep it open
6. in PuttyGen, click "Load" to load your .pem file
7. Keep the SSH-2 RSA radio button checked. Click on "Save private key" You'll get pop-up window warning, click "Yes”
8. click on "Save public key" as well, so to generate the public key. This is the public key that we're going to copy across to your current instance
9. Save the public key with the new key pair name and with the extension .pub
10. Open the public key content in a notepad
11. copy the content below "Comment: "imported-openssh-key" and before "---- END SSH2 PUBLIC KEY ----
    Note - you need to copy the content as one line - delete all new lines
12. on your connected instance, open your authorized_keys file using the tool vi. Run the following command: vi .ssh/authorized_keys you should see the original public key in the file also
13. move your cursor on the file to the end of your first public key content :type "i" for insert
14. on the new line, type "ssh-rsa" and add a space before you paste the content of the public key , space, and the name of the .pem file (without the .pem) Note - you should get a line with the same format as the previous line
15. press the Esc key, and then type :wq!

this will save the updated authorized_keys file

now try open a new SSH session to your instance using your new key pai

When you've confirmed you're able to SSH into the instance using the new key pair, u can vi .ssh/authorized_key and delete the old key.

Answer to Shaggie remark:

If you are unable to connect to the instance (e.g. key is corrupted) than use the AWS console to detach the volume (http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-detaching-volume.html) and reattach it to working instance, than change the key on the volume and reattach it back to the previous instance.

Put finish() just after

Intent i = new Intent(Summary1.this,MainActivity.class);
            startActivity(i);
finish();

You can set the following environment variable:

PIP_TARGET=/path/to/pip/dir

https://pip.pypa.io/en/stable/user_guide/#environment-variables

I use this rule for my applications:

x.y.z

Where:

• x = main version number, 1-~.
• y = feature number, 0-9. Increase this number if the change contains new features with or without bug fixes.
• z = hotfix number, 0-~. Increase this number if the change only contains bug fixes.

Example:

• For new application, the version number starts with 1.0.0.
• If the new version contains only bug fixes, increase the hotfix number so the version number will be 1.0.1.
• If the new version contains new features with or without bug fixes, increase the feature number and reset the hotfix number to zero so the version number will be 1.1.0. If the feature number reaches 9, increase the main version number and reset the feature and hotfix number to zero (2.0.0 etc)

This will make exactly what you were expecting:

Objective-C:

 [myButton.titleLabel setTextAlignment:UITextAlignmentCenter];

For iOS 6 or higher it's

 [myButton.titleLabel setTextAlignment: NSTextAlignmentCenter];

as explained in tyler53's answer

Swift:

myButton.titleLabel?.textAlignment = NSTextAlignment.Center

Swift 4.x and above

myButton.titleLabel?.textAlignment = .center

ack works with similar arguments as grep, and accepts -C. But it's usually better for searching through code.

The question is already answered... but I wanted to show how to add shadow and change the font with NSAttributedString as well, so that when people search for this topic they won't have to keep looking.

#define FONT_SIZE 20
#define FONT_HELVETICA @"Helvetica-Light"
#define BLACK_SHADOW [UIColor colorWithRed:40.0f/255.0f green:40.0f/255.0f blue:40.0f/255.0f alpha:0.4f]

NSString*myNSString = @"This is my string.\nIt goes to a second line.";                

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
               paragraphStyle.alignment = NSTextAlignmentCenter;
             paragraphStyle.lineSpacing = FONT_SIZE/2;
                     UIFont * labelFont = [UIFont fontWithName:FONT_HELVETICA size:FONT_SIZE];
                   UIColor * labelColor = [UIColor colorWithWhite:1 alpha:1];
                       NSShadow *shadow = [[NSShadow alloc] init];
                 [shadow setShadowColor : BLACK_SHADOW];
                [shadow setShadowOffset : CGSizeMake (1.0, 1.0)];
            [shadow setShadowBlurRadius : 1];

NSAttributedString *labelText = [[NSAttributedString alloc] initWithString : myNSString
                      attributes : @{
   NSParagraphStyleAttributeName : paragraphStyle,
             NSKernAttributeName : @2.0,
             NSFontAttributeName : labelFont,
  NSForegroundColorAttributeName : labelColor,
           NSShadowAttributeName : shadow }];

Here is a Swift version...

Warning! This works for 4s.

For 5s you have to change all of the the Float values to Double values (because the compiler isn't working correctly yet)

Swift enum for font choice:

enum FontValue: Int {
    case FVBold = 1 , FVCondensedBlack, FVMedium, FVHelveticaNeue, FVLight, FVCondensedBold, FVLightItalic, FVUltraLightItalic, FVUltraLight, FVBoldItalic, FVItalic
}

Swift array for enum access (needed because enum can't use '-'):

func helveticaFont (index:Int) -> (String) {
    let fontArray = [
    "HelveticaNeue-Bold",
    "HelveticaNeue-CondensedBlack",
    "HelveticaNeue-Medium",
    "HelveticaNeue",
    "HelveticaNeue-Light",
    "HelveticaNeue-CondensedBold",
    "HelveticaNeue-LightItalic",
    "HelveticaNeue-UltraLightItalic",
    "HelveticaNeue-UltraLight",
    "HelveticaNeue-BoldItalic",
    "HelveticaNeue-Italic",
    ]
    return fontArray[index]
}

Swift attributed text function:

func myAttributedText (myString:String, mySize: Float, myFont:FontValue) -> (NSMutableAttributedString) {

    let shadow = NSShadow()
    shadow.shadowColor = UIColor.textShadowColor()
    shadow.shadowOffset = CGSizeMake (1.0, 1.0)
    shadow.shadowBlurRadius = 1

    let paragraphStyle = NSMutableParagraphStyle.alloc()
    paragraphStyle.lineHeightMultiple = 1
    paragraphStyle.lineBreakMode = NSLineBreakMode.ByWordWrapping
    paragraphStyle.alignment = NSTextAlignment.Center

    let labelFont = UIFont(name: helveticaFont(myFont.toRaw()), size: mySize)
    let labelColor = UIColor.whiteColor()

    let myAttributes :Dictionary = [NSParagraphStyleAttributeName : paragraphStyle,
                                              NSKernAttributeName : 3, // (-1,5)
                                              NSFontAttributeName : labelFont,
                                   NSForegroundColorAttributeName : labelColor,
                                            NSShadowAttributeName : shadow]

    let myAttributedString = NSMutableAttributedString (string: myString, attributes:myAttributes)

    // add new color 
    let secondColor = UIColor.blackColor()
    let stringArray = myString.componentsSeparatedByString(" ")
    let firstString: String? = stringArray.first
    let letterCount = countElements(firstString!)
    if firstString {
        myAttributedString.addAttributes([NSForegroundColorAttributeName:secondColor], range:NSMakeRange(0,letterCount))
    }

    return  myAttributedString
}

first and last extension used for finding ranges in a string array:

extension Array {
    var last: T? {
        if self.isEmpty {
            NSLog("array crash error - please fix")
            return self [0]
        } else {
            return self[self.endIndex - 1]
        }
    }
}

extension Array {
    var first: T? {
        if self.isEmpty {
            NSLog("array crash error - please fix")
            return self [0]
        } else {
            return self [0]
        }
    }
}

new colors:

extension UIColor {
    class func shadowColor() -> UIColor {
        return UIColor(red: 0.0/255.0, green: 0.0/255.0, blue: 0.0/255.0, alpha: 0.3)
    }
    class func textShadowColor() -> UIColor {
        return UIColor(red: 50.0/255.0, green: 50.0/255.0, blue: 50.0/255.0, alpha: 0.5)
    }
    class func pastelBlueColor() -> UIColor {
        return UIColor(red: 176.0/255.0, green: 186.0/255.0, blue: 255.0/255.0, alpha: 1)
    }
    class func pastelYellowColor() -> UIColor {
        return UIColor(red: 255.0/255.0, green: 238.0/255.0, blue: 140.0/255.0, alpha: 1)
    }
}

my macro replacement:

enum MyConstants: Float {
    case CornerRadius = 5.0
}

my button maker w/attributed text:

    let myButton = UIButton.buttonWithType(.System) as UIButton
    myButton.backgroundColor = UIColor.pastelBlueColor()
    myButton.showsTouchWhenHighlighted = true;

    myLabel.numberOfLines = 5
    myLabel.tag = 100
    myLabel.layer.cornerRadius = myLabel.bounds.size.width / MyConstants.CornerRadius.toRaw()
    myLabel.clipsToBounds = true
    myLabel.layerborders()

    myBaseView.addSubview(myLabel)

    myBaseView.layerShadow()
    myBaseView.layerGradient()

    myView.addSubview(myBaseView)

    return myLabel
}

generic shadow add:

func viewshadow<T where T: UIView> (shadowObject: T)
{
    let layer = shadowObject.layer
    let radius = shadowObject.frame.size.width / MyConstants.CornerRadius.toRaw();
    layer.borderColor = UIColor.whiteColor().CGColor
    layer.borderWidth = 0.8
    layer.cornerRadius = radius
    layer.shadowOpacity = 1
    layer.shadowRadius = 3
    layer.shadowOffset = CGSizeMake(2.0,2.0)
    layer.shadowColor = UIColor.shadowColor().CGColor
}

view extension for view style:

extension UIView {
    func layerborders() {
        let layer = self.layer
        let frame = self.frame
        let myColor = self.backgroundColor
        layer.borderColor = myColor.CGColor
        layer.borderWidth = 10.8
        layer.cornerRadius = layer.borderWidth / MyConstants.CornerRadius.toRaw()
    }

    func layerShadow() {
        let layer = self.layer
        let frame = self.frame
        layer.cornerRadius = layer.borderWidth / MyConstants.CornerRadius.toRaw()
        layer.shadowOpacity = 1
        layer.shadowRadius = 3
        layer.shadowOffset = CGSizeMake(2.0,2.0)
        layer.shadowColor = UIColor.shadowColor().CGColor
    }

    func layerGradient() {
        let layer = CAGradientLayer()
        let size = self.frame.size
        layer.frame.size = size
        layer.frame.origin = CGPointMake(0.0,0.0)
        layer.cornerRadius = layer.bounds.size.width / MyConstants.CornerRadius.toRaw();

        var color0 = CGColorCreateGenericRGB(250.0/255, 250.0/255, 250.0/255, 0.5)
        var color1 = CGColorCreateGenericRGB(200.0/255, 200.0/255, 200.0/255, 0.1)
        var color2 = CGColorCreateGenericRGB(150.0/255, 150.0/255, 150.0/255, 0.1)
        var color3 = CGColorCreateGenericRGB(100.0/255, 100.0/255, 100.0/255, 0.1)
        var color4 = CGColorCreateGenericRGB(50.0/255, 50.0/255, 50.0/255, 0.1)
        var color5 = CGColorCreateGenericRGB(0.0/255, 0.0/255, 0.0/255, 0.1)
        var color6 = CGColorCreateGenericRGB(150.0/255, 150.0/255, 150.0/255, 0.1)

        layer.colors = [color0,color1,color2,color3,color4,color5,color6]
        self.layer.insertSublayer(layer, atIndex: 2)
    }
}

the actual view did load function:

func buttonPress (sender:UIButton!) {
    NSLog("%@", "ButtonPressed")
}

override func viewDidLoad() {
    super.viewDidLoad()

    let myLabel = myLabelMaker(myView)
    let myButton = myButtonMaker(myView)

    myButton.addTarget(self, action: "buttonPress:", forControlEvents:UIControlEvents.TouchUpInside)

    viewshadow(myButton)
    viewshadow(myLabel)

}

In case could be useful for anyone that uses rh-* packages this worked for me:

sudo ln -s /opt/rh/rh-nodejs8/root/usr/bin/npm /usr/local/bin/npm

You can use the

myDropDown.Items.Remove(ListItem li);

or

myDropDown.Items.RemoveAt(int index);

to remove it using C#.

The better and correct solution is to have a directive. The scope is the same, whether in the controller of the directive or the main controller. Use $element to do DOM operations. The method defined in the directive controller is accessible in the main controller.

Example, finding a child element:

var app = angular.module('myapp', []);
app.directive("testDir", function () {
    function link(scope, element) { 

    }
    return {
        restrict: "AE", 
        link: link, 
        controller:function($scope,$element){
            $scope.name2 = 'this is second name';
            var barGridSection = $element.find('#barGridSection'); //helps to find the child element.
    }
    };
})

app.controller('mainController', function ($scope) {
$scope.name='this is first name'
});

Here is how I do a Subview on iOS in Swift -

class CustomSubview : UIView {

    init() {
        super.init(frame: UIScreen.mainScreen().bounds);

        let windowHeight : CGFloat = 150;
        let windowWidth  : CGFloat = 360;

        self.backgroundColor = UIColor.whiteColor();
        self.frame = CGRectMake(0, 0, windowWidth, windowHeight);
        self.center = CGPoint(x: UIScreen.mainScreen().bounds.width/2, y: 375);

        //for debug validation
        self.backgroundColor = UIColor.grayColor();
        print("My Custom Init");

        return;
    }

    required init?(coder aDecoder: NSCoder) { fatalError("init(coder:) has not been implemented"); }
}

INSERT INTO KeyedTable(KeyField, Otherfield)
SELECT n.* FROM 
    (SELECT 'PossibleDupeLiteral' AS KeyField, 'OtherfieldValue' AS Otherfield
     UNION ALL
     SELECT 'PossibleDupeLiteral', 'OtherfieldValue2'
    )
LEFT JOIN KeyedTable k
    ON k.KeyField=n.KeyField
WHERE k.KeyField IS NULL

This tells the Server to look for the same data (hopefully the same speedy way it does to check for duplicate keys) and insert nothing if it finds it.

I like the IGNORE_DUP_KEY solution too, but then anyone who relies on errors to catch problems will be mystified when the server silently ignores their dupe-key errors.

The reason I choose this over Philip Kelley's solution is that you can provide several rows of data and only have the missing ones actually get in:

You should be able to set the server.session.timeout in your application.properties file.

ref: http://docs.spring.io/spring-boot/docs/1.4.x/reference/html/common-application-properties.html

From "Find duplicate rows with PostgreSQL" here's smart solution:

select * from (
  SELECT id,
  ROW_NUMBER() OVER(PARTITION BY column1, column2 ORDER BY id asc) AS Row
  FROM tbl
) dups
where 
dups.Row > 1

As others pointed out it is usually the simplest to remove the line that is unnecessarily stubbing a method call.

In my case it was in a @BeforeEach and it was relevant most of the time. In the only test where that method was not used I reset the mock, e.g.:

myMock.reset()

Hope this helps others with the same problem.

(Note that if there are multiple mocked calls on the same mock this could be inconvenient as well since you'll have to mock all the other methods except the one that isn't called.)

Javascript Keycodes

• e.keyCode == 8 for backspace
• e.keyCode == 46 for forward backspace or delete button in PC's

^{Except this detail Colin & Tod's answer is working.}

The problem is that they're all the same exact list in memory. When you use the [x]*n syntax, what you get is a list of n many x objects, but they're all references to the same object. They're not distinct instances, rather, just n references to the same instance.

To make a list of 3 different lists, do this:

x = [[] for i in range(3)]

This gives you 3 separate instances of [], which is what you want

[[]]*n is similar to

l = []
x = []
for i in range(n):
    x.append(l)

While [[] for i in range(3)] is similar to:

x = []
for i in range(n):
    x.append([])   # appending a new list!

In [20]: x = [[]] * 4

In [21]: [id(i) for i in x]
Out[21]: [164363948, 164363948, 164363948, 164363948] # same id()'s for each list,i.e same object


In [22]: x=[[] for i in range(4)]

In [23]: [id(i) for i in x]
Out[23]: [164382060, 164364140, 164363628, 164381292] #different id(), i.e unique objects this time

You can try doing:

String myResource = IOUtils.toString(this.getClass().getResourceAsStream("yourfile.xml")).replace("\n","");

In addition to previous post you can have

<h:form rendered="#{!bean.boolvalue}" />
<h:form rendered="#{bean.textvalue == 'value'}" />

Jsf 2.0

Here's my regexp pure JavaScript solution:

function highlight(text) {
    document.body.innerHTML = document.body.innerHTML.replace(
        new RegExp(text + '(?!([^<]+)?<)', 'gi'),
        '<b style="background-color:#ff0;font-size:100%">$&</b>'
    );
}

dougg3 has this pretty much (I can't comment there). The main additional thing you need to know is the headers which don't conflict with each other but do provide the correct prototypes. The answer is

#include <stropts.h>
#include <asm/termios.h>

After that you can use dougg3's code, preferably with error checking round the ioctl() calls. You will probably need to put this in a separate .c file to the rest of your serial port code which uses the normal termios to set other parameters. Doing POSIX manipulations first, then this to set the custom speed, works fine on the built-in UART of the Raspberry Pi to get a 250k baud rate.

This is largely a duplicate of another question.

Here's the section of that answer that is relevant to this question:

Do I need to do my own synchronization if I use java.util.ConcurrentLinkedQueue?

Atomic operations on the concurrent collections are synchronized for you. In other words, each individual call to the queue is guaranteed thread-safe without any action on your part. What is not guaranteed thread-safe are any operations you perform on the collection that are non-atomic.

For example, this is threadsafe without any action on your part:

queue.add(obj);

or

queue.poll(obj);

However; non-atomic calls to the queue are not automatically thread-safe. For example, the following operations are not automatically threadsafe:

if(!queue.isEmpty()) {
   queue.poll(obj);
}

That last one is not threadsafe, as it is very possible that between the time isEmpty is called and the time poll is called, other threads will have added or removed items from the queue. The threadsafe way to perform this is like this:

synchronized(queue) {
    if(!queue.isEmpty()) {
       queue.poll(obj);
    }
}

Again...atomic calls to the queue are automatically thread-safe. Non-atomic calls are not.

You can use python-docx2txt library to read text from Microsoft Word documents. It is an improvement over python-docx library as it can, in addition, extract text from links, headers and footers. It can even extract images.

You can install it by running: pip install docx2txt.

Let's download and read the first Microsoft document on here:

import docx2txt
my_text = docx2txt.process("test.docx")
print(my_text)

Here is a screenshot of the Terminal output the above code:

EDIT:

This does NOT work for .doc files. The only reason I am keep this answer is that it seems there are people who find it useful for .docx files.

If anyone is here for WebApi (not MVC) you just return the ModelState object:

return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ModelState);

The root of it all is to make sure that the requests are coming from the actual users of the site. A csrf token is generated for the forms and Must be tied to the user's sessions. It is used to send requests to the server, in which the token validates them. This is one way of protecting against csrf, another would be checking the referrer header.

This worked for me:

$("[id*=txtName]").on('keydown', function(e) { var keyCode = e.keyCode || e.which; if (keyCode == 9) { e.preventDefault(); alert('Tab Pressed'); } });

From C++11 onwards, all the standard containers (std::vector, std::map, etc) support move semantics, meaning that you can now pass rvalues to standard containers and avoid a copy:

// Example object class.
class object
{
private:
    int             m_val1;
    std::string     m_val2;

public:
    // Constructor for object class.
    object(int val1, std::string &&val2) :
        m_val1(val1),
        m_val2(std::move(val2))
    {

    }
};

std::vector<object> myList;

// #1 Copy into the vector.
object foo1(1, "foo");
myList.push_back(foo1);

// #2 Move into the vector (no copy).
object foo2(1024, "bar");
myList.push_back(std::move(foo2));

// #3 Move temporary into vector (no copy).
myList.push_back(object(453, "baz"));

// #4 Create instance of object directly inside the vector (no copy, no move).
myList.emplace_back(453, "qux");

Alternatively you can use various smart pointers to get mostly the same effect:

std::unique_ptr example

std::vector<std::unique_ptr<object>> myPtrList;

// #5a unique_ptr can only ever be moved.
auto pFoo = std::make_unique<object>(1, "foo");
myPtrList.push_back(std::move(pFoo));

// #5b unique_ptr can only ever be moved.
myPtrList.push_back(std::make_unique<object>(1, "foo"));

std::shared_ptr example

std::vector<std::shared_ptr<object>> objectPtrList2;

// #6 shared_ptr can be used to retain a copy of the pointer and update both the vector
// value and the local copy simultaneously.
auto pFooShared = std::make_shared<object>(1, "foo");
objectPtrList2.push_back(pFooShared);
// Pointer to object stored in the vector, but pFooShared is still valid.

If you remove the files in the directory (with git rm as the other answers explain), then the directory no longer exists as far as git is concerned. You cannot commit an empty directory, nor can you remove one.

This is unlike subversion where you have to explicitly svn rm emptyfolder/, and is incidentally why the man page for git describes itself as "the stupid content tracker"

An answer on "How do I add an empty directory to a git repository" links to the FAQ on this subject:

Currently the design of the git index (staging area) only permits files to be listed, and nobody competent enough to make the change to allow empty directories has cared enough about this situation to remedy it.

Directories are added automatically when adding files inside them. That is, directories never have to be added to the repository, and are not tracked on their own.

You can say "git add <dir>" and it will add files in there.

If you really need a directory to exist in checkouts you should create a file in it. .gitignore works well for this purpose; you can leave it empty, or fill in the names of files you expect to show up in the directory.

The word check_ in the name means that if the command (the shell in this case that returns the exit status of the last command (yum in this case)) returns non-zero status then it raises CalledProcessError exception. It is by design. If the command that you want to run may return non-zero status on success then either catch this exception or don't use check_ methods. You could use subprocess.call in your case because you are ignoring the captured output, e.g.:

import subprocess

rc = subprocess.call(['grep', 'pattern', 'file'],
                     stdout=subprocess.DEVNULL, stderr=subprocess.STDOUT)
if rc == 0: # found
   ...
elif rc == 1: # not found
   ...
elif rc > 1: # error
   ...

You don't need shell=True to run the commands from your question.

I have finally managed to properly add back button to actionbar/toolbar

@Override
public void onCreate(Bundle savedInstanceState) {
    ...
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}  

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            finish();
            return true;
    }

    return super.onOptionsItemSelected(item);
}

public boolean onCreateOptionsMenu(Menu menu) {
    return true;
}

If you config wkhtmltopdf for Rails or Somethings in Centos, you can follow these step bellow:

1. Go to https://wkhtmltopdf.org/downloads.html and copied the link of rpm file.

In centos server bash.

2. wget link_of_wkhtmltopdf_rpm.rpm

3. rpm -ivh link_of_wkhtmltopdf_rpm.rpm

4. which wkhtmltopdf

=> You will get path of wkhtmltopdf.

5. Setup for wicked_pdf or pdfkit with path in step 4. This is sample config with wickedpdf. config/initializers/wicked_pdf.rb

   if Rails.env != "production"
       path = %x[which wkhtmltopdf].gsub(/\n/, "")
   else
       path = "path_of_wkhtmltopdf_in_step_4"
   end
   WickedPdf.config = { exe_path: path }
   

6. Restart server.

DONE.

Try the following code. In most case, it is caused by the comma issue.

cast(replace([FIELD NAME],',','') as float)

Javascript isn't threaded, so a "wait" would freeze the entire page (and probably cause the browser to stop running the script entirely).

To specifically address your problem, you should remove the brackets after donothing in your setTimeout call, and make waitsecs a number not a string:

console.log('before');
setTimeout(donothing,500); // run donothing after 0.5 seconds
console.log('after');

But that won't stop execution; "after" will be logged before your function runs.

To wait properly, you can use anonymous functions:

console.log('before');
setTimeout(function(){
    console.log('after');
},500);

All your variables will still be there in the "after" section. You shouldn't chain these - if you find yourself needing to, you need to look at how you're structuring the program. Also you may want to use setInterval / clearInterval if it needs to loop.

We can't say that it is possible of not their is some other way exist to perform update operation in user-defined Function. Directly DML is not possible in UDF it is for sure.

Below Query is working perfectly:

create table testTbl
(
id int identity(1,1) Not null,
name nvarchar(100)
)
GO

insert into testTbl values('ajay'),('amit'),('akhil')
Go

create function tblValued()
returns Table
as
return (select * from testTbl where id = 1)
Go

update tblValued() set name ='ajay sharma' where id = 1
Go

select * from testTbl 
Go

Minimal example

And just to make what Mizux said as a minimal example:

main_c.c

#include <stdio.h>

int main(void) {
    puts("hello");
}

main_cpp.cpp

#include <iostream>

int main(void) {
    std::cout << "hello" << std::endl;
}

Then, without any Makefile:

make CFLAGS='-g -O3' \
     CXXFLAGS='-ggdb3 -O0' \
     CPPFLAGS='-DX=1 -DY=2' \
     CCFLAGS='--asdf' \
     main_c \
     main_cpp

runs:

cc -g -O3 -DX=1 -DY=2   main_c.c   -o main_c
g++ -ggdb3 -O0 -DX=1 -DY=2   main_cpp.cpp   -o main_cpp

So we understand that:

• make had implicit rules to make main_c and main_cpp from main_c.c and main_cpp.cpp
• CFLAGS and CPPFLAGS were used as part of the implicit rule for .c compilation
• CXXFLAGS and CPPFLAGS were used as part of the implicit rule for .cpp compilation
• CCFLAGS is not used

Those variables are only used in make's implicit rules automatically: if compilation had used our own explicit rules, then we would have to explicitly use those variables as in:

main_c: main_c.c
    $(CC) $(CFLAGS) $(CPPFLAGS) -o $@ $<

main_cpp: main_c.c
    $(CXX) $(CXXFLAGS) $(CPPFLAGS) -o $@ $<

to achieve a similar affect to the implicit rules.

We could also name those variables however we want: but since Make already treats them magically in the implicit rules, those make good name choices.

Tested in Ubuntu 16.04, GNU Make 4.1.

It's actually a sensible question. Here's the answer from Excel 2010 help:

"The Workbook object is a member of the Workbooks collection. The Workbooks collection contains all the Workbook objects currently open in Microsoft Excel."

So, since that workbook isn't open - at least I assume it isn't - it can't be set as a workbook object. If it was open you'd just set it like:

Set wbk = workbooks("Master Benchmark Data Sheet.xlsx")

In Java you can get the keys using ListObjects (see AWS documentation)

FileWriter fileWriter;
BufferedWriter bufferedWriter;
// [...]

AmazonS3 s3client = new AmazonS3Client(new ProfileCredentialsProvider());        

ListObjectsRequest listObjectsRequest = new ListObjectsRequest()
.withBucketName(bucketName)
.withPrefix("myprefix");
ObjectListing objectListing;

do {
    objectListing = s3client.listObjects(listObjectsRequest);
    for (S3ObjectSummary objectSummary : 
        objectListing.getObjectSummaries()) {
        // write to file with e.g. a bufferedWriter
        bufferedWriter.write(objectSummary.getKey());
    }
    listObjectsRequest.setMarker(objectListing.getNextMarker());
} while (objectListing.isTruncated());

I don't think the status bar color has been implemented in AppCompat yet. These are the attributes which are available:

    <!-- ============= -->
    <!-- Color palette -->
    <!-- ============= -->

    <!-- The primary branding color for the app. By default, this is the color applied to the
         action bar background. -->
    <attr name="colorPrimary" format="color" />

    <!-- Dark variant of the primary branding color. By default, this is the color applied to
         the status bar (via statusBarColor) and navigation bar (via navigationBarColor). -->
    <attr name="colorPrimaryDark" format="color" />

    <!-- Bright complement to the primary branding color. By default, this is the color applied
         to framework controls (via colorControlActivated). -->
    <attr name="colorAccent" format="color" />

    <!-- The color applied to framework controls in their normal state. -->
    <attr name="colorControlNormal" format="color" />

    <!-- The color applied to framework controls in their activated (ex. checked) state. -->
    <attr name="colorControlActivated" format="color" />

    <!-- The color applied to framework control highlights (ex. ripples, list selectors). -->
    <attr name="colorControlHighlight" format="color" />

    <!-- The color applied to framework buttons in their normal state. -->
    <attr name="colorButtonNormal" format="color" />

    <!-- The color applied to framework switch thumbs in their normal state. -->
    <attr name="colorSwitchThumbNormal" format="color" />

You don't need any calls to pthread_exit(3) in your particular code.

In general, the main thread should not call pthread_exit, but should often call pthread_join(3) to wait for some other thread to finish.

In your PrintHello function, you don't need to call pthread_exit because it is implicit after returning from it.

So your code should rather be:

void *PrintHello(void *threadid)  {
  long tid = (long)threadid;
  printf("Hello World! It's me, thread #%ld!\n", tid);
  return threadid;
}

int main (int argc, char *argv[]) {
   pthread_t threads[NUM_THREADS];
   int rc;
   intptr_t t;
   // create all the threads
   for(t=0; t<NUM_THREADS; t++){
     printf("In main: creating thread %ld\n", (long) t);
     rc = pthread_create(&threads[t], NULL, PrintHello, (void *)t);
     if (rc) { fprintf(stderr, "failed to create thread #%ld - %s\n",
                                (long)t, strerror(rc));
               exit(EXIT_FAILURE);
             };
   }
   pthread_yield(); // useful to give other threads more chance to run
   // join all the threads
   for(t=0; t<NUM_THREADS; t++){
      printf("In main: joining thread #%ld\n", (long) t);
      rc = pthread_join(&threads[t], NULL);
      if (rc) { fprintf(stderr, "failed to join thread #%ld - %s\n",
                                (long)t, strerror(rc));
               exit(EXIT_FAILURE);
      }
   }
}

Old question, new answer. With C++11 we have the fancy new for loop:

for (const auto &s : schemas)
   names.push_back(s.first);

where schemas is a std::map and names is an std::vector.

This populates the array (names) with keys from the map (schemas); change s.first to s.second to get an array of values.

I found two links of performance compare among several ways of converting string to int.

parseInt(str,10)    
parseFloat(str)
str << 0
+str
str*1 
str-0
Number(str)

Since I was not too happy with the output of other (non-tree) answers (see my comment at Hassou's answer), I tried to mimic trees output a bit more.

It's similar to the answer of Robert but the horizontal lines do not all start at the beginning, but where there are supposed to start. Had to use perl though, but in my case, on the system where I don't have tree, perl is available.

ls -aR | grep ":$" | perl -pe 's/:$//;s/[^-][^\/]*\//    /g;s/^    (\S)/+-- \1/;s/(^    |    (?= ))/¦   /g;s/    (\S)/+-- \1/'

Output (shortened):

.
+-- fd
+-- net
¦   +-- dev_snmp6
¦   +-- nfsfs
¦   +-- rpc
¦   ¦   +-- auth.unix.ip
¦   +-- stat
¦   +-- vlan
+-- ns
+-- task
¦   +-- 1310
¦   ¦   +-- net
¦   ¦   ¦   +-- dev_snmp6
¦   ¦   ¦   +-- rpc
¦   ¦   ¦   ¦   +-- auth.unix.gid
¦   ¦   ¦   ¦   +-- auth.unix.ip
¦   ¦   ¦   +-- stat
¦   ¦   ¦   +-- vlan
¦   ¦   +-- ns

Suggestions to avoid the superfluous vertical lines are welcome :-)

I still like Ben's solution in the comment of Hassou's answer very much, without the (not perfectly correct) lines it's much cleaner. For my use case I additionally removed the global indentation and added the option to also ls hidden files, like so:

ls -aR | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//  /g'

Output (shortened even more):

.
  fd
  net
    dev_snmp6
    nfsfs
    rpc
      auth.unix.ip
    stat
    vlan
  ns

var i;

if (i === null || typeof i === 'undefined') {
    console.log(i, 'i is undefined or null')
}
else {
    console.log(i, 'i has some value')
}

This code is based on the most voted question but I might be easier to use

public enum OS {

    WINDOWS,
    MAC,
    LINUX,
    ANDROID,
    IPHONE,
    UNKNOWN;

    public static OS valueOf(HttpServletRequest request) {

        final String userAgent = request.getHeader("User-Agent");
        final OS toReturn;

        if (userAgent == null || userAgent.isEmpty()) {
            toReturn = UNKNOWN;
        } else if (userAgent.toLowerCase().contains("windows")) {
            toReturn = WINDOWS;
        } else if (userAgent.toLowerCase().contains("mac")) {
            toReturn = MAC;
        } else if (userAgent.toLowerCase().contains("x11")) {
            toReturn = LINUX;
        } else if (userAgent.toLowerCase().contains("android")) {
            toReturn = ANDROID;
        } else if (userAgent.toLowerCase().contains("iphone")) {
            toReturn = IPHONE;
        } else {
            toReturn = UNKNOWN;
        }

        return toReturn;
    }

}

The latest version of elementtree supports XPath pretty well. Not being an XPath expert I can't say for sure if the implementation is full but it has satisfied most of my needs when working in Python. I've also use lxml and PyXML and I find etree nice because it's a standard module.

NOTE: I've since found lxml and for me it's definitely the best XML lib out there for Python. It does XPath nicely as well (though again perhaps not a full implementation).

if you can control creating/passing the settings object, i'd recommend using an ExpandoObject instead.

dynamic settings = new ExpandoObject();
settings.Filename = "asdf.txt";
settings.Size = 10;
...

function void Settings(dynamic settings)
{
    if ( ((IDictionary<string, object>)settings).ContainsKey("Filename") )
        .... do something ....
}

There is an article here that describes your problem

With the Material Components Library you can use the com.google.android.material.textfield.TextInputLayout.

You can apply a custom style to change the colors.

To change the hint color you have to use these attributes:
hintTextColor and android:textColorHint.

<style name="Custom_textinputlayout_filledbox" parent="@style/Widget.MaterialComponents.TextInputLayout.FilledBox">
    <!-- The color of the label when it is collapsed and the text field is active -->
    <item name="hintTextColor">?attr/colorPrimary</item>

    <!-- The color of the label in all other text field states (such as resting and disabled) -->
    <item name="android:textColorHint">@color/selector_hint_text_color</item>
</style>

You should use a selector for the android:textColorHint. Something like:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:alpha="0.38" android:color="?attr/colorOnSurface" android:state_enabled="false"/>
  <item android:alpha="0.6" android:color="?attr/colorOnSurface"/>
</selector>

To change the bottom line color you have to use the attribute: boxStrokeColor.

<style name="Custom_textinputlayout_filledbox" parent="@style/Widget.MaterialComponents.TextInputLayout.FilledBox">
    ....
    <item name="boxStrokeColor">@color/selector_stroke_color</item>
</style>

Also in this case you should use a selector. Something like:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:color="?attr/colorPrimary" android:state_focused="true"/>
  <item android:alpha="0.87" android:color="?attr/colorOnSurface" android:state_hovered="true"/>
  <item android:alpha="0.12" android:color="?attr/colorOnSurface" android:state_enabled="false"/>
  <item android:alpha="0.38" android:color="?attr/colorOnSurface"/>
</selector>

You can also apply these attributes in your layout:

<com.google.android.material.textfield.TextInputLayout
    style="@style/Widget.MaterialComponents.TextInputLayout.FilledBox"
    app:boxStrokeColor="@color/selector_stroke_color"
    app:hintTextColor="?attr/colorPrimary"
    android:textColorHint="@color/selector_hint_text_color"
    ...>

When the tree structure is large, Angular (up to 1.4.x) becomes very slow at rendering a recursive template. After trying a number of these suggestions, I ended up creating a simple HTML string and using ng-bind-html to display it. Of course, this is not the way to use Angular features

A bare-bones recursive function is shown here (with minimal HTML):

function menu_tree(menu, prefix) {
    var html = '<div>' + prefix + menu.menu_name + ' - ' + menu.menu_desc + '</div>\n';
    if (!menu.items) return html;
    prefix += menu.menu_name + '/';
    for (var i=0; i<menu.items.length; ++i) {
        var item = menu.items[i];
        html += menu_tree(item, prefix);
    }
    return html;
}
// Generate the tree view and tell Angular to trust this HTML
$scope.html_menu = $sce.trustAsHtml(menu_tree(menu, ''));

In the template, it only needs this one line:

<div ng-bind-html="html_menu"></div>

This bypasses all of Angular's data binding and simply displays the HTML in a fraction of the time of the recursive template methods.

With a menu structure like this (a partial file tree of a Linux file system):

menu = {menu_name: '', menu_desc: 'root', items: [
            {menu_name: 'bin', menu_desc: 'Essential command binaries', items: [
                {menu_name: 'arch', menu_desc: 'print machine architecture'},
                {menu_name: 'bash', menu_desc: 'GNU Bourne-Again SHell'},
                {menu_name: 'cat', menu_desc: 'concatenate and print files'},
                {menu_name: 'date', menu_desc: 'display or set date and time'},
                {menu_name: '...', menu_desc: 'other files'}
            ]},
            {menu_name: 'boot', menu_desc: 'Static files of the boot loader'},
            {menu_name: 'dev', menu_desc: 'Device files'},
            {menu_name: 'etc', menu_desc: 'Host-specific system configuration'},
            {menu_name: 'lib', menu_desc: 'Essential shared libraries and kernel modules'},
            {menu_name: 'media', menu_desc: 'Mount point for removable media'},
            {menu_name: 'mnt', menu_desc: 'Mount point for mounting a filesystem temporarily'},
            {menu_name: 'opt', menu_desc: 'Add-on application software packages'},
            {menu_name: 'sbin', menu_desc: 'Essential system binaries'},
            {menu_name: 'srv', menu_desc: 'Data for services provided by this system'},
            {menu_name: 'tmp', menu_desc: 'Temporary files'},
            {menu_name: 'usr', menu_desc: 'Secondary hierarchy', items: [
                {menu_name: 'bin', menu_desc: 'user utilities and applications'},
                {menu_name: 'include', menu_desc: ''},
                {menu_name: 'local', menu_desc: '', items: [
                    {menu_name: 'bin', menu_desc: 'local user binaries'},
                    {menu_name: 'games', menu_desc: 'local user games'}
                ]},
                {menu_name: 'sbin', menu_desc: ''},
                {menu_name: 'share', menu_desc: ''},
                {menu_name: '...', menu_desc: 'other files'}
            ]},
            {menu_name: 'var', menu_desc: 'Variable data'}
        ]
       }

The output becomes:

- root
/bin - Essential command binaries
/bin/arch - print machine architecture
/bin/bash - GNU Bourne-Again SHell
/bin/cat - concatenate and print files
/bin/date - display or set date and time
/bin/... - other files
/boot - Static files of the boot loader
/dev - Device files
/etc - Host-specific system configuration
/lib - Essential shared libraries and kernel modules
/media - Mount point for removable media
/mnt - Mount point for mounting a filesystem temporarily
/opt - Add-on application software packages
/sbin - Essential system binaries
/srv - Data for services provided by this system
/tmp - Temporary files
/usr - Secondary hierarchy
/usr/bin - user utilities and applications
/usr/include -
/usr/local -
/usr/local/bin - local user binaries
/usr/local/games - local user games
/usr/sbin -
/usr/share -
/usr/... - other files
/var - Variable data

If you want to use the value of the email input somewhere else on the same page, for example to do some sort of validation, you could use JavaScript. First I would assign an "id" attribute to your email textbox:

<input type="text" name="email" id="email"/>

and then I would retrieve the value with JavaScript:

var email = document.getElementById('email').value;

From there, you can do additional processing on the value of 'email'.

I was also facing same issues, and after lot of research found the solution:

1. Your min sdk version should be same as of the modules you are using eg: your module min sdk version is 14 and your app min sdk version is 9 It should be same.
2. If build version of your app and modules not same. Again it should same ** In short, your app build.gradle file and manifest should have same configurations**
3. There's no duplicacy like same permissions added in manifest file twice, same activity mention twice.
4. If you have delete any activity from your project, delete it from your manifest file as well.
5. Sometimes its because of label, icon etc tag of manifest file:

a) Add the xmlns:tools line in the manifest tag.

b) Add tools:replace= or tools:ignore= in the application tag.

Example:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.slinfy.ikharelimiteduk"
    xmlns:tools="http://schemas.android.com/tools"
    android:versionCode="1"
    android:versionName="1.0" >

  <application
      tools:replace="icon, label"
      android:label="myApp"
      android:name="com.example.MyApplication"
      android:allowBackup="true"
      android:hardwareAccelerated="false"
      android:icon="@drawable/ic_launcher"
      android:theme="@style/Theme.AppCompat" >
  </application>

</manifest>

6. If two dependencies are of not same version example: you are using dependency for appcompat v7:26.0.0 and for facebook com.facebook.android:facebook-android-sdk:[4,5) facebook uses cardview of version com.android.support:cardview-v7:25.3.1 and appcompat v7:26.0.0 uses cardview of version v7:26.0.0, So there is discripancy in two libraries and thus give error

Error:Execution failed for task ':app:processDebugManifest'.

Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.0.0-alpha1) from [com.android.support:appcompat-v7:26.0.0-alpha1] AndroidManifest.xml:27:9-38 is also present at [com.android.support:cardview-v7:25.3.1] AndroidManifest.xml:24:9-31 value=(25.3.1). Suggestion: add 'tools:replace="android:value"' to element at AndroidManifest.xml:25:5-27:41 to override.

So by using appcompat of version 25.3.1, We can avoid this error

By considering above points in mind, you will get rid of this irritating issue. You can check my blog too https://wordpress.com/post/dhingrakimmi.wordpress.com/23

There you go, this is what I used to fix your problem:

CSS CODE

nav ul { list-style-type: none; }

HTML CODE

<nav>
<ul>
<li><a href="#">Milk</a>
   <ul>
   <li><a href="#">Goat</a></li>
   <li><a href="#">Cow</a></li>
   </ul>
</li>
<li><a href="#">Eggs</a>
   <ul>
   <li><a href="#">Free-range</a></li>
   <li><a href="#">Other</a></li>

<li><a href="#">Cheese</a>
   <ul>
   <li><a href="#">Smelly</a></li>
   <li><a href="#">Extra smelly</a></li>

As of Jackson 1.6, you can use:

JsonNode node = mapper.valueToTree(map);

or

JsonNode node = mapper.convertValue(object, JsonNode.class);

The best solution for any browser that lack a console is:

// Avoid `console` errors in browsers that lack a console.
(function() {
    var method;
    var noop = function () {};
    var methods = [
        'assert', 'clear', 'count', 'debug', 'dir', 'dirxml', 'error',
        'exception', 'group', 'groupCollapsed', 'groupEnd', 'info', 'log',
        'markTimeline', 'profile', 'profileEnd', 'table', 'time', 'timeEnd',
        'timeStamp', 'trace', 'warn'
    ];
    var length = methods.length;
    var console = (window.console = window.console || {});

    while (length--) {
        method = methods[length];

        // Only stub undefined methods.
        if (!console[method]) {
            console[method] = noop;
        }
    }
}());

For text:

[RangeObject].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

For cell background

[RangeObject].Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

I am using Primefaces with glassfish and SQL Server.

in my case i created the Webfilter, in back-end, to get every request and convert to UTF-8, like this:

package br.com.teste.filter;

import java.io.IOException;

import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.annotation.WebFilter;

@WebFilter(servletNames={"Faces Servlet"})
public class Filter implements javax.servlet.Filter {

    @Override
    public void destroy() {
        // TODO Auto-generated method stub

    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response,
            FilterChain chain) throws IOException, ServletException {
        request.setCharacterEncoding("UTF-8");
        chain.doFilter(request, response);      
    }

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        // TODO Auto-generated method stub      
    }

}

In the View (.xhtml) i need to set the enctype paremeter's form to UTF-8 like @Kevin Rahe:

    <h:form id="frmt" enctype="multipart/form-data;charset=UTF-8" >
         <!-- your code here -->
    </h:form>  

Check out the example from enable-cors.org:

In your ExpressJS app on node.js, do the following with your routes:

app.all('/', function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Headers", "X-Requested-With");
  next();
 });

app.get('/', function(req, res, next) {
  // Handle the get for this route
});

app.post('/', function(req, res, next) {
 // Handle the post for this route
});

The first call (app.all) should be made before all the other routes in your app (or at least the ones you want to be CORS enabled).

[Edit]

If you want the headers to show up for static files as well, try this (make sure it's before the call to use(express.static()):

app.use(function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Headers", "X-Requested-With");
  next();
});

I tested this with your code, and got the headers on assets from the public directory:

var express = require('express')
  , app = express.createServer();

app.configure(function () {
    app.use(express.methodOverride());
    app.use(express.bodyParser());
    app.use(function(req, res, next) {
      res.header("Access-Control-Allow-Origin", "*");
      res.header("Access-Control-Allow-Headers", "X-Requested-With");
      next();
    });
    app.use(app.router);
});

app.configure('development', function () {
    app.use(express.static(__dirname + '/public'));
    app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));
});

app.configure('production', function () {
    app.use(express.static(__dirname + '/public'));
    app.use(express.errorHandler());
});

app.listen(8888);
console.log('express running at http://localhost:%d', 8888);

You could, of course, package the function up into a module so you can do something like

// cors.js

module.exports = function() {
  return function(req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "X-Requested-With");
    next();
  };
}

// server.js

cors = require('./cors');
app.use(cors());

If youre using a .ssh/config file try to

chmod 0400 .ssh/config

then:

chmod 0400 .ssh/<<KEYFILE_PATH>>

You can pass "<>" (including the quotes) as the parameter for criteria. This basically says, as long as its not empty/blank, count it. I believe this is what you want.

=COUNTIF(A1:A10, "<>") 

Otherwise you can use CountA as Scott suggests

I think you are looking for qsort.
qsort function is the implementation of quicksort algorithm found in stdlib.h in C/C++.

Here is the syntax to call qsort function:

void qsort(void *base, size_t nmemb, size_t size,int (*compar)(const void *, const void *));

List of arguments:

base: pointer to the first element or base address of the array
nmemb: number of elements in the array
size: size in bytes of each element
compar: a function that compares two elements

Here is a code example which uses qsort to sort an array:

#include <stdio.h>
#include <stdlib.h>

int arr[] = { 33, 12, 6, 2, 76 };

// compare function, compares two elements
int compare (const void * num1, const void * num2) {
   if(*(int*)num1 > *(int*)num2)
    return 1;
   else
    return -1;
}

int main () {
   int i;

   printf("Before sorting the array: \n");
   for( i = 0 ; i < 5; i++ ) {
      printf("%d ", arr[i]);
   }
   // calling qsort
   qsort(arr, 5, sizeof(int), compare);

   printf("\nAfter sorting the array: \n");
   for( i = 0 ; i < 5; i++ ) {   
      printf("%d ", arr[i]);
   }
  
   return 0;
}

You can type man 3 qsort in Linux/Mac terminal to get a detailed info about qsort.
Link to qsort man page

Binding the scroll event after the ul has loaded using ajax has solved the issue. In my findings $(document).on( 'scroll', '#id', function () {...}) is not working and binding the scroll event after the ajax load found working.

$("#ulId").bind('scroll', function() {
   console.log('Event worked');
}); 

You may unbind the event after removing or replacing the ul.

Hope it may help someone.

An alternative, I think for your purpose, is to use the round() function:

select round((10 * 1.5),2) // prints 15.00

You can try it here:

Default values in appcompat-v7

<dimen name="abc_text_size_body_1_material">14sp</dimen>
<dimen name="abc_text_size_body_2_material">14sp</dimen>
<dimen name="abc_text_size_button_material">14sp</dimen>
<dimen name="abc_text_size_caption_material">12sp</dimen>
<dimen name="abc_text_size_display_1_material">34sp</dimen>
<dimen name="abc_text_size_display_2_material">45sp</dimen>
<dimen name="abc_text_size_display_3_material">56sp</dimen>
<dimen name="abc_text_size_display_4_material">112sp</dimen>
<dimen name="abc_text_size_headline_material">24sp</dimen>
<dimen name="abc_text_size_large_material">22sp</dimen>
<dimen name="abc_text_size_medium_material">18sp</dimen>
<dimen name="abc_text_size_menu_material">16sp</dimen>
<dimen name="abc_text_size_small_material">14sp</dimen>
<dimen name="abc_text_size_subhead_material">16sp</dimen>
<dimen name="abc_text_size_subtitle_material_toolbar">16dp</dimen>
<dimen name="abc_text_size_title_material">20sp</dimen>
<dimen name="abc_text_size_title_material_toolbar">20dp</dimen>

I think this problem can be solved in this way:

 <TextView
        android:id="@+id/leftText"
        android:includeFontPadding="false"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="30dp"
        android:text="Hello World!\nhello world" />

 <TextView
        android:id="@+id/rightUpperText"
        android:includeFontPadding="false"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@+id/leftText"
        android:layout_alignTop="@+id/leftText"
        android:textSize="30dp"
        android:text="Hello World!" />

 <TextView
        android:id="@+id/rightLowerText"
        android:includeFontPadding="false"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@+id/leftText"
        android:layout_below="@+id/rightUpperText"
        android:textSize="30dp"
        android:text="hello world" />

Those are the results:

ScreenShot-1

ScreenShot-3

Though the line of special characters in rightLowerText looks a little bit higher than the second line of leftText, their baselines are stilled aligned.

for Oracle Database 10g users:

alter table mytable modify(mycolumn null);

You get "ORA-01735: invalid ALTER TABLE option" when you try otherwise

ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;

One major difference that is important to know is that ActiveX controls show up as objects that you can use in your code- try inserting an ActiveX control into a worksheet, bring up the VBA editor (ALT + F11) and you will be able to access the control programatically. You can't do this with form controls (macros must instead be explicitly assigned to each control), but form controls are a little easier to use. If you are just doing something simple, it doesn't matter which you use but for more advanced scripts ActiveX has better possibilities.

ActiveX is also more customizable.

Associative Arrays in JavaScript don't really work the same as they do in other languages. for each statements are complicated (because they enumerate inherited prototype properties). You could declare properties on an object/associative array as Pointy mentioned, but really for this sort of thing you should use an array with the push method:

jsArr = []; 

for (var i = 1; i <= 10; i++) { 
    jsArr.push('example ' + 1); 
} 

Just don't forget that indexed arrays are zero-based so the first element will be jsArr[0], not jsArr[1].

I wanted the Number same as I get from database for example.

1) 00100.220000

2) 00123

3) 0000.0000100

So I modified the code as below

$objPHPExcel->getActiveSheet()
    ->setCellValue('A3', '00100.220000');
$objPHPExcel->getActiveSheet()
    ->getStyle('A3')
    ->getNumberFormat()
    ->setFormatCode('00000.000000');


$objPHPExcel->getActiveSheet()
    ->setCellValue('A4', '00123');
$objPHPExcel->getActiveSheet()
  ->getStyle('A4')
 ->getNumberFormat()
->setFormatCode('00000');


$objPHPExcel->getActiveSheet()
    ->setCellValue('A5', '0000.0000100');
$objPHPExcel->getActiveSheet()
  ->getStyle('A5')
 ->getNumberFormat()
->setFormatCode('0000.0000000');

These specific lines are the usual wrapper for jQuery plugins:

"...to make sure that your plugin doesn't collide with other libraries that might use the dollar sign, it's a best practice to pass jQuery to a self executing function (closure) that maps it to the dollar sign so it can't be overwritten by another library in the scope of its execution."

(function( $ ){
  $.fn.myPlugin = function() {
    // Do your awesome plugin stuff here
  };
})( jQuery );

From http://docs.jquery.com/Plugins/Authoring

Same as @axtavt, but you can use also the RequestDispatcher constant.

request.getAttribute(RequestDispatcher.FORWARD_REQUEST_URI);

I Would suggest the following:

var="any given string"
N=${#var}
G=${var//g/}
G=${#G}
(( G = N - G ))
echo "$G"

No call to any other program

LinkedHashMap is precisely what you're looking for.

It is exactly like HashMap, except that when you iterate over it, it presents the items in the insertion order.

I ran into the same error, turns out that the manifest file had some errors. After fixing it, clicked Make Project again, it worked fine. Android studio sometimes do not give very helpful error messages.

There is an old Bugreport concerning this issue.

As already stated, enum instances should be uppercase according to the docs on the Oracle website (http://docs.oracle.com/javase/tutorial/java/javaOO/enum.html).

However, while looking through a JavaEE7 tutorial on the Oracle website (http://www.oracle.com/technetwork/java/javaee/downloads/index.html), I stumbled across the "Duke's bookstore" tutorial and in a class (tutorial\examples\case-studies\dukes-bookstore\src\main\java\javaeetutorial\dukesbookstore\components\AreaComponent.java), I found the following enum definition:

private enum PropertyKeys {
    alt, coords, shape, targetImage;
}

According to the conventions, it should have looked like:

public enum PropertyKeys {
    ALT("alt"), COORDS("coords"), SHAPE("shape"), TARGET_IMAGE("targetImage");

    private final String val;

    private PropertyKeys(String val) {
        this.val = val;
    }

    @Override
    public String toString() {
        return val;
    }
}

So it seems even the guys at Oracle sometimes trade convention with convenience.

Assuming you use Java 5 enums (which is not so certain since you mention old Enumeration class), you can use the valueOf method of java.lang.Enum subclass:

MyEnum e = MyEnum.valueOf("ONE_OF_CONSTANTS");

I fixed a similar issue building a RadioButtonFor with pairs of text/value from a SelectList. I used a ViewBag to send the SelectList to the View, but you can use data from model too. My web application is a Blog and I have to build a RadioButton with some types of articles when he is writing a new post.

The code below was simplyfied.

List<SelectListItem> items = new List<SelectListItem>();

Dictionary<string, string> dictionary = new Dictionary<string, string>();

dictionary.Add("Texto", "1");
dictionary.Add("Foto", "2");
dictionary.Add("Vídeo", "3");

foreach (KeyValuePair<string, string> pair in objBLL.GetTiposPost())
{
    items.Add(new SelectListItem() { Text = pair.Key, Value = pair.Value, Selected = false });
}

ViewBag.TiposPost = new SelectList(items, "Value", "Text");

In the View, I used a foreach to build a radiobutton.

<div class="form-group">
    <div class="col-sm-10">
        @foreach (var item in (SelectList)ViewBag.TiposPost)
        {
            @Html.RadioButtonFor(model => model.IDTipoPost, item.Value, false)
            <label class="control-label">@item.Text</label>
        }

    </div>
</div>

Notice that I used RadioButtonFor in order to catch the option value selected by user, in the Controler, after submit the form. I also had to put the item.Text outside the RadioButtonFor in order to show the text options.

Hope it's useful!

That's a specific case of the rule that you shouldn't catch any exception you don't know how to handle. If you don't know how to handle it, it's always better to let some other part of the system catch and handle it.

The documentation says:

class (Optional) String
One or more CSS classes to remove from the elements, these are separated by spaces.

Example:

Remove the class 'blue' and 'under' from the matched elements.

$("p:odd").removeClass("blue under");

With Git 2.23 (August 2019), that would be, using git switch -f:

git switch -f master

That avoids the confusion with git checkout (which deals with files or branches).

And that will proceeds, even if the index or the working tree differs from HEAD.
Both the index and working tree are restored to match the switching target.
If --recurse-submodules is specified, submodule content is also restored to match the switching target.
This is used to throw away local changes.

I solved this by subclassing UILabel and overriding drawTextInRect: like this:

- (void)drawTextInRect:(CGRect)rect {
    UIEdgeInsets insets = {0, 5, 0, 5};
    [super drawTextInRect:UIEdgeInsetsInsetRect(rect, insets)];
}

Swift 3.1:

override func drawText(in rect: CGRect) {
    let insets = UIEdgeInsets.init(top: 0, left: 5, bottom: 0, right: 5)
    super.drawText(in: UIEdgeInsetsInsetRect(rect, insets))
}

Swift 4.2.1:

override func drawText(in rect: CGRect) {
    let insets = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
    super.drawText(in: rect.inset(by: insets))
}

As you might have gathered, this is an adaptation of tc.'s answer. It has two advantages over that one:

1. there's no need to trigger it by sending a sizeToFit message
2. it leaves the label frame alone - handy if your label has a background and you don't want that to shrink

We have a tomcat-8.5 + restlet-2.3.4 + hibernate-4.2.0 + log4j-1.2.14 java 8 app running on AlpineLinux in docker.

On adding these 2 lines to /usr/local/tomcat/webapps/ROOT/WEB-INF/classes/log4j.properties, I started seeing the HQL queries in the logs:

### log just the SQL
log4j.logger.org.hibernate.SQL=debug

### log JDBC bind parameters ###
log4j.logger.org.hibernate.type=debug

However, the JDBC bind parameters are not being logged.

int x = -1;
Calendar cal = ...;
cal.add(Calendar.DATE, x);

See java.util.Calendar#add(int,int)

Cast the operands to floats:

float ans = (float)a / (float)b;

Give the Exec Maven plugin a try

Curiously, I was able to solve the same issue by doing the exact opposite move to svc's ! I had to :

1) replace the FQDN hostname in my tnsnames.ora / listener.ora files with localhost, and restart the listener service, and

2) two, I had to use "SYS as SYSDBA" as the username in the SQL Developer input textbox

to finally be able to have SQL Developer hook to my local instance.

You can edit Rprofile in the base library (in 'C:/Program Files/R.Files/library/base/R' by default) to include code to be run on startup. Append

########        User code        ########
.libPaths('C:/my/dir')

to Rprofile using any text editor (like Notepad) to cause R to add 'C:/my/dir' to the list of libraries it knows about.

(Notepad can't save to Program Files, so save your edited Rprofile somewhere else and then copy it in using Windows Explorer.)

Just helpful information - here is newest TypeScript / JavaScript runtime Deno.

Java SE Development Kit 8u112 on a 64-bit Windows 7 or Windows 8

Set the following user environment variables (== environment variables of type user variables)

• JAVA_HOME : C:\Program Files\Java\jdk1.8.0_112
• JDK_HOME : %JAVA_HOME%
• JRE_HOME : %JAVA_HOME%\jre
• CLASSPATH : .;%JAVA_HOME%\lib;%JAVA_HOME%\jre\lib
• PATH : your-unique-entries;%JAVA_HOME%\bin (make sure that the longish your-unique-entries does not contain any other references to another Java installation folder.

Note for Windows users on 64-bit systems:

Progra~1 = 'Program Files'
Progra~2 = 'Program Files(x86)'

Notice that these environment variables are derived from the "root" environment variable JAVA_HOME. This makes it easy to update your environment variables when updating the JDK. Just point JAVA_HOME to the fresh installation.

There is a blogpost explaining the rationale behind all these environment variables.

Optional recommendations

• Add an user environment variable JAVA_TOOL_OPTIONS with value -Dfile.encoding="UTF-8". This ensures that Java (and tools such as Maven) will run with a Charset.defaultCharset() of UTF-8 (instead of the default Windows-1252). This has saved a lot of headaches when wirking with my own code and that of others, which unfortunately often assume the (sane) default encoding UTF-8.
• When JDK is installed, it adds to the system environment variable Path an entry C:\ProgramData\Oracle\Java\javapath;. I anecdotally noticed that the links in that directory didn't get updated during an JDK installation update. So it's best to remove C:\ProgramData\Oracle\Java\javapath; from the Path system environment variable in order to have a consistent environment.

Disconnected recordsets can be useful.

Const adVarChar = 200  'the SQL datatype is varchar

'Create a disconnected recordset
Set rs = CreateObject("ADODB.RECORDSET")
rs.Fields.append "SortField", adVarChar, 25

rs.CursorType = adOpenStatic
rs.Open
rs.AddNew "SortField", "Some data"
rs.Update
rs.AddNew "SortField", "All data"
rs.Update

rs.Sort = "SortField"

rs.MoveFirst

Do Until rs.EOF
    strList=strList & vbCrLf & rs.Fields("SortField")        
    rs.MoveNext
Loop 

MsgBox strList

I had a difficult time in finding a way in XCode 7.2, but finally I had found one. First press Shift+Command+ H twice. This will open up all the apps that are currently open.

Swipe left/right to the app you actually want to close. Just Swipe Up using the Touchpad while Holding the App would close the app.

That depends on how the fragment is structured. If you can have some of the methods on the Fragment Class B static and also the target TextView object static, you can call the method directly on Fragment Class A. This is better than a listener as the method is performed instantaneously, and we don't need to have an additional task that performs listening throughout the activity. See example below:

Fragment_class_B.setmyText(String yourstring);

On Fragment B you can have the method defined as:

public static void setmyText(final String string) {
myTextView.setText(string);
}

Just don't forget to have myTextView set as static on Fragment B, and properly import the Fragment B class on Fragment A.

Just did the procedure on my project recently and it worked. Hope that helped.

I've been thinking about this too. From a C background, you can simulate function return code types, as well as, parameter types, using something like the following:

function top_function() {
    var rc;
    console.log("1st call");
    rc = Number(test_function("number", 1, "string", "my string"));
    console.log("typeof rc: " + typeof rc + "   rc: " + rc);
    console.log("2nd call");
    rc = Number(test_function("number", "a", "string", "my string"));
    console.log("typeof rc: " + typeof rc + "   rc: " + rc);
}
function test_function(parm_type_1, parm_val_1, parm_type_2, parm_val_2) {
    if (typeof parm_val_1 !== parm_type_1) console.log("Parm 1 not correct type");
    if (typeof parm_val_2 !== parm_type_2) console.log("Parm 2 not correct type");
    return parm_val_1;
}

The Number before the calling function returns a Number type regardless of the type of the actual value returned, as seen in the 2nd call where typeof rc = number but the value is NaN

the console.log for the above is:

1st call
typeof rc: number   rc: 1
2nd call
Parm 1 not correct type
typeof rc: number   rc: NaN

Solution: In order to increase your buffer history on iterm bash terminal you've got two options:

Go to iterm -> Preferences -> Profiles -> Terminal Tab -> Scrollback Buffer (section)

Option 1. select the checkbox Unlimited scrollback

Option 2. type the selected Scrollback lines numbers you'd like your terminal buffer to cache (See image below)

extern template is only needed if the template declaration is complete

This was hinted at in other answers, but I don't think enough emphasis was given to it.

What this means is that in the OPs examples, the extern template has no effect because the template definitions on the headers were incomplete:

• void f();: just declaration, no body
• class foo: declares method f() but has no definition

So I would recommend just removing the extern template definition in that particular case: you only need to add them if the classes are completely defined.

For example:

TemplHeader.h

template<typename T>
void f();

TemplCpp.cpp

template<typename T>
void f(){}

// Explicit instantiation for char.
template void f<char>();

Main.cpp

#include "TemplHeader.h"

// Commented out from OP code, has no effect.
// extern template void f<T>(); //is this correct?

int main() {
    f<char>();
    return 0;
}

compile and view symbols with nm:

g++ -std=c++11 -Wall -Wextra -pedantic -c -o TemplCpp.o TemplCpp.cpp
g++ -std=c++11 -Wall -Wextra -pedantic -c -o Main.o Main.cpp
g++ -std=c++11 -Wall -Wextra -pedantic -o Main.out Main.o TemplCpp.o
echo TemplCpp.o
nm -C TemplCpp.o | grep f
echo Main.o
nm -C Main.o | grep f

output:

TemplCpp.o
0000000000000000 W void f<char>()
Main.o
                 U void f<char>()

and then from man nm we see that U means undefined, so the definition did stay only on TemplCpp as desired.

All this boils down to the tradeoff of complete header declarations:

• upsides:
  • allows external code to use our template with new types
  • we have the option of not adding explicit instantiations if we are fine with object bloat
• downsides:
  • when developing that class, header implementation changes will lead smart build systems to rebuild all includers, which could be many many files
  • if we want to avoid object file bloat, we need not only to do explicit instantiations (same as with incomplete header declarations) but also add extern template on every includer, which programmers will likely forget to do

Further examples of those are shown at: Explicit template instantiation - when is it used?

Since compilation time is so critical in large projects, I would highly recommend incomplete template declarations, unless external parties absolutely need to reuse your code with their own complex custom classes.

And in that case, I would first try to use polymorphism to avoid the build time problem, and only use templates if noticeable performance gains can be made.

You can not "attach" a SASS/SCSS file to an HTML document.

SASS/SCSS is a CSS preprocessor that runs on the server and compiles to CSS code that your browser understands.

There are client-side alternatives to SASS that can be compiled in the browser using javascript such as LESS CSS, though I advise you compile to CSS for production use.

It's as simple as adding 2 lines of code to your HTML file.

<link rel="stylesheet/less" type="text/css" href="styles.less" />
<script src="less.js" type="text/javascript"></script>

Here it is how to use MockHttpServletRequest:

// given
MockHttpServletRequest request = new MockHttpServletRequest();
request.setServerName("www.example.com");
request.setRequestURI("/foo");
request.setQueryString("param1=value1&param");

// when
String url = request.getRequestURL() + '?' + request.getQueryString(); // assuming there is always queryString.

// then
assertThat(url, is("http://www.example.com:80/foo?param1=value1&param"));

I find it important to note that python 3 defines the opening modes differently to the answers here that were correct for Python 2.

The Pyhton 3 opening modes are:

'r' open for reading (default)
'w' open for writing, truncating the file first
'x' open for exclusive creation, failing if the file already exists
'a' open for writing, appending to the end of the file if it exists
----
'b' binary mode
't' text mode (default)
'+' open a disk file for updating (reading and writing)
'U' universal newlines mode (for backwards compatibility; should not be used in new code)

The modes r, w, x, a are combined with the mode modifiers b or t. + is optionally added, U should be avoided.

As I found out the hard way, it is a good idea to always specify t when opening a file in text mode since r is an alias for rt in the standard open() function but an alias for rb in the open() functions of all compression modules (when e.g. reading a *.bz2 file).

Thus the modes for opening a file should be:

rt / wt / xt / at for reading / writing / creating / appending to a file in text mode and

rb / wb / xb / ab for reading / writing / creating / appending to a file in binary mode.

Use + as before.

Whevever you get a problem like this just go to the man page for the function in question and it will tell you what header you are missing, e.g.

$ man memset

MEMSET(3)                BSD Library Functions Manual                MEMSET(3)

NAME
     memset -- fill a byte string with a byte value

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <string.h>

     void *
     memset(void *b, int c, size_t len);

Note that for C++ it's generally preferable to use the proper equivalent C++ headers, <cstring>/<cstdio>/<cstdlib>/etc, rather than C's <string.h>/<stdio.h>/<stdlib.h>/etc.

If you look at the documentation for str.split:

If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace. Consequently, splitting an empty string or a string consisting of just whitespace with a None separator returns [].

In other words, if you're trying to figure out what to pass to split to get '\n\tName: Jane Smith' to ['Name:', 'Jane', 'Smith'], just pass nothing (or None).

This almost solves your whole problem. There are two parts left.

First, you've only got two fields, the second of which can contain spaces. So, you only want one split, not as many as possible. So:

s.split(None, 1)

Next, you've still got those pesky colons. But you don't need to split on them. At least given the data you've shown us, the colon always appears at the end of the first field, with no space before and always space after, so you can just remove it:

key, value = s.split(None, 1)
key = key[:-1]

There are a million other ways to do this, of course; this is just the one that seems closest to what you were already trying.

Follow following steps:

1. Copy hello.ko to /lib/modules/'uname-r'/misc/
2. Add misc/hello.ko entry in /lib/modules/'uname-r'/modules.dep
3. sudo depmod
4. sudo modprobe hello

modprobe will check modules.dep file for any dependency.

I found a useful function present in web3 library.

var hexString = "0x1231ac"
string strValue = web3.toAscii(hexString)

Reading the original comment, rutherford is looking for a cross-browser way to wrap unbroken text (inferred by his use of word-wrap for IE, designed to break unbroken strings).

/* Source: http://snipplr.com/view/10979/css-cross-browser-word-wrap */
.wordwrap { 
   white-space: pre-wrap;      /* CSS3 */   
   white-space: -moz-pre-wrap; /* Firefox */    
   white-space: -pre-wrap;     /* Opera <7 */   
   white-space: -o-pre-wrap;   /* Opera 7 */    
   word-wrap: break-word;      /* IE */
}

I've used this class for a bit now, and works like a charm. (note: I've only tested in FireFox and IE)

Actually, all of those examples on the web wherein the common content/file type like "js", "css", "img", etc is been used as library name are misleading.

Real world examples

To start, let's look at how existing JSF implementations like Mojarra and MyFaces and JSF component libraries like PrimeFaces and OmniFaces use it. No one of them use resource libraries this way. They use it (under the covers, by @ResourceDependency or UIViewRoot#addComponentResource()) the following way:

<h:outputScript library="javax.faces" name="jsf.js" />
<h:outputScript library="primefaces" name="jquery/jquery.js" />
<h:outputScript library="omnifaces" name="omnifaces.js" />
<h:outputScript library="omnifaces" name="fixviewstate.js" />
<h:outputScript library="omnifaces.combined" name="[dynamicname].js" />
<h:outputStylesheet library="primefaces" name="primefaces.css" />
<h:outputStylesheet library="primefaces-aristo" name="theme.css" />
<h:outputStylesheet library="primefaces-vader" name="theme.css" />

It should become clear that it basically represents the common library/module/theme name where all of those resources commonly belong to.

Easier identifying

This way it's so much easier to specify and distinguish where those resources belong to and/or are coming from. Imagine that you happen to have a primefaces.css resource in your own webapp wherein you're overriding/finetuning some default CSS of PrimeFaces; if PrimeFaces didn't use a library name for its own primefaces.css, then the PrimeFaces own one wouldn't be loaded, but instead the webapp-supplied one, which would break the look'n'feel.

Also, when you're using a custom ResourceHandler, you can also apply more finer grained control over resources coming from a specific library when library is used the right way. If all component libraries would have used "js" for all their JS files, how would the ResourceHandler ever distinguish if it's coming from a specific component library? Examples are OmniFaces CombinedResourceHandler and GraphicResourceHandler; check the createResource() method wherein the library is checked before delegating to next resource handler in chain. This way they know when to create CombinedResource or GraphicResource for the purpose.

Noted should be that RichFaces did it wrong. It didn't use any library at all and homebrewed another resource handling layer over it and it's therefore impossible to programmatically identify RichFaces resources. That's exactly the reason why OmniFaces CombinedResourceHander had to introduce a reflection-based hack in order to get it to work anyway with RichFaces resources.

Your own webapp

Your own webapp does not necessarily need a resource library. You'd best just omit it.

<h:outputStylesheet name="css/style.css" />
<h:outputScript name="js/script.js" />
<h:graphicImage name="img/logo.png" />

Or, if you really need to have one, you can just give it a more sensible common name, like "default" or some company name.

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

Or, when the resources are specific to some master Facelets template, you could also give it the name of the template, so that it's easier to relate each other. In other words, it's more for self-documentary purposes. E.g. in a /WEB-INF/templates/layout.xhtml template file:

<h:outputStylesheet library="layout" name="css/style.css" />
<h:outputScript library="layout" name="js/script.js" />

And a /WEB-INF/templates/admin.xhtml template file:

<h:outputStylesheet library="admin" name="css/style.css" />
<h:outputScript library="admin" name="js/script.js" />

For a real world example, check the OmniFaces showcase source code.

Or, when you'd like to share the same resources over multiple webapps and have created a "common" project for that based on the same example as in this answer which is in turn embedded as JAR in webapp's /WEB-INF/lib, then also reference it as library (name is free to your choice; component libraries like OmniFaces and PrimeFaces also work that way):

<h:outputStylesheet library="common" name="css/style.css" />
<h:outputScript library="common" name="js/script.js" />
<h:graphicImage library="common" name="img/logo.png" />

Library versioning

Another main advantage is that you can apply resource library versioning the right way on resources provided by your own webapp (this doesn't work for resources embedded in a JAR). You can create a direct child subfolder in the library folder with a name in the \d+(_\d+)* pattern to denote the resource library version.

WebContent
 |-- resources
 |    `-- default
 |         `-- 1_0
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

When using this markup:

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

This will generate the following HTML with the library version as v parameter:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_0" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_0"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_0" alt="" />

So, if you have edited/updated some resource, then all you need to do is to copy or rename the version folder into a new value. If you have multiple version folders, then the JSF ResourceHandler will automatically serve the resource from the highest version number, according to numerical ordering rules.

So, when copying/renaming resources/default/1_0/* folder into resources/default/1_1/* like follows:

WebContent
 |-- resources
 |    `-- default
 |         |-- 1_0
 |         |    :
 |         |
 |         `-- 1_1
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

Then the last markup example would generate the following HTML:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_1" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_1"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_1" alt="" />

This will force the webbrowser to request the resource straight from the server instead of showing the one with the same name from the cache, when the URL with the changed parameter is been requested for the first time. This way the endusers aren't required to do a hard refresh (Ctrl+F5 and so on) when they need to retrieve the updated CSS/JS resource.

Please note that library versioning is not possible for resources enclosed in a JAR file. You'd need a custom ResourceHandler. See also How to use JSF versioning for resources in jar.

There is nothing inherently wrong with using a break statement but nested loops can get confusing. To improve readability many languages (at least Java does) support breaking to labels which will greatly improve readability.

int[] iArray = new int[]{0,1,2,3,4,5,6,7,8,9};
int[] jArray = new int[]{0,1,2,3,4,5,6,7,8,9};

// label for i loop
iLoop: for (int i = 0; i < iArray.length; i++) {

    // label for j loop
    jLoop: for (int j = 0; j < jArray.length; j++) {

        if(iArray[i] < jArray[j]){
            // break i and j loops
            break iLoop;
        } else if (iArray[i] > jArray[j]){  
            // breaks only j loop
            break jLoop;
        } else {
            // unclear which loop is ending
            // (breaks only the j loop)
            break;
        }
    }
}

I will say that break (and return) statements often increase cyclomatic complexity which makes it harder to prove code is doing the correct thing in all cases.

If you're considering using a break while iterating over a sequence for some particular item, you might want to reconsider the data structure used to hold your data. Using something like a Set or Map may provide better results.

The best approach to use yum and update your devtoolset is to utilize the CentOS SCLo RH Testing repository.

yum install centos-release-scl-rh
yum --enablerepo=centos-sclo-rh-testing install devtoolset-7-gcc devtoolset-7-gcc-c++

Many additional packages are also available, to see them all

yum --enablerepo=centos-sclo-rh-testing list devtoolset-7*

You can use this method to install any dev tool version, just swap the 7 for your desired version. devtoolset-6-gcc, devtoolset-5-gcc etc.

Use the "dot space script" calling syntax. For example, here's how to do it using the full path to a script:

. /path/to/set_env_vars.sh

And here's how to do it if you're in the same directory as the script:

. set_env_vars.sh

These execute the script under the current shell instead of loading another one (which is what would happen if you did ./set_env_vars.sh). Because it runs in the same shell, the environmental variables you set will be available when it exits.

This is the same thing as calling source set_env_vars.sh, but it's shorter to type and might work in some places where source doesn't.

Bearer token is one or more repetition of alphabet, digit, "-" , "." , "_" , "~" , "+" , "/" followed by 0 or more "=".

RFC 6750 2.1. Authorization Request Header Field (Format is ABNF (Augmented BNF))

The syntax for Bearer credentials is as follows:

     b64token    = 1*( ALPHA / DIGIT /
                       "-" / "." / "_" / "~" / "+" / "/" ) *"="
     credentials = "Bearer" 1*SP b64token

It looks like Base64 but according to Should the token in the header be base64 encoded?, it is not.

Digging a bit deeper in to "HTTP/1.1, part 7: Authentication"**, however, I see that b64token is just an ABNF syntax definition allowing for characters typically used in base64, base64url, etc.. So the b64token doesn't define any encoding or decoding but rather just defines what characters can be used in the part of the Authorization header that will contain the access token.

This fully addresses the first 3 items in the OP question's list. So I'm extending this answer to address the 4th question, about whether the token must be validated, so @mon feel free to remove or edit:

The authorizer is responsible for accepting or rejecting the http request. If the authorizer says the token is valid, it's up to you to decide what this means:

• Does the authorizer have a way of inspecting the URL, identifying the operation, and looking up some role-based access control database to see if it is allowed? If yes and the request comes through, the service can assume it is allowed, and does not need to verify.
• Is the token an all-or-nothing, so if the token is correct, all operations are allowed? Then the service doesn't need to verify.
• Does the token mean "this request is allowed, but here is the UUID for the role, you check whether the operation is allowed". Then it's up to the service to look up that role, and see if the operation is allowed.

There should be a container that maps component names to all components that are supposed to be used dynamically. Component classes should be registered in a container because in modular environment there's otherwise no single place where they could be accessed. Component classes cannot be identified by their names without specifying them explicitly because function name is minified in production.

Component map

It can be plain object:

class Foo extends React.Component { ... }
...
const componentsMap = { Foo, Bar };
...
const componentName = 'Fo' + 'o';
const DynamicComponent = componentsMap[componentName];
<DynamicComponent/>;

Or Map instance:

const componentsMap = new Map([[Foo, Foo], [Bar, Bar]]);
...
const DynamicComponent = componentsMap.get(componentName);

Plain object is more suitable because it benefits from property shorthand.

Barrel module

A barrel module with named exports can act as such map:

// Foo.js
export class Foo extends React.Component { ... }

// dynamic-components.js
export * from './Foo';
export * from './Bar';

// some module that uses dynamic component
import * as componentsMap from './dynamic-components';

const componentName = 'Fo' + 'o';
const DynamicComponent = componentsMap[componentName];
<DynamicComponent/>;

This works well with one class per module code style.

Decorator

Decorators can be used with class components for syntactic sugar, this still requires to specify class names explicitly and register them in a map:

const componentsMap = {};

function dynamic(Component) {
  if (!Component.displayName)
    throw new Error('no name');

  componentsMap[Component.displayName] = Component;

  return Component;
}

...

@dynamic
class Foo extends React.Component {
  static displayName = 'Foo'
  ...
}

A decorator can be used as higher-order component with functional components:

const Bar = props => ...;
Bar.displayName = 'Bar';

export default dynamic(Bar);

The use of non-standard displayName instead of random property also benefits debugging.

The default behaviour of divs is to take the full width available in their parent container.
This is the same as if you'd give the inner divs a width of 100%.

By floating the divs, they ignore their default and size their width to fit the content. Everything behind it (in the HTML), is placed under the div (on the rendered page).
This is the reason that they align theirselves next to each other.

The float CSS property specifies that an element should be taken from the normal flow and placed along the left or right side of its container, where text and inline elements will wrap around it. A floating element is one where the computed value of float is not none.

Source: https://developer.mozilla.org/en-US/docs/Web/CSS/float

Get rid of the float, and the divs will be aligned under each other.
If this does not happen, you'll have some other css on divs or children of wrapper defining a floating behaviour or an inline display.

If you want to keep the float, for whatever reason, you can use clear on the 2nd div to reset the floating properties of elements before that element.
clear has 5 valid values: none | left | right | both | inherit. Clearing no floats (used to override inherited properties), left or right floats or both floats. Inherit means it'll inherit the behaviour of the parent element

Also, because of the default behaviour, you don't need to set the width and height on auto.
You only need this is you want to set a hardcoded height/width. E.g. 80% / 800px / 500em / ...

<div id="wrapper">
    <div id="inner1"></div>
    <div id="inner2"></div>
</div>

CSS is

#wrapper{
    margin-left:auto;
    margin-right:auto;
    height:auto; // this is not needed, as parent container, this div will size automaticly
    width:auto; // this is not needed, as parent container, this div will size automaticly
}

/*
You can get rid of the inner divs in the css, unless you want to style them.
If you want to style them identicly, you can use concatenation
*/
#inner1, #inner2 {
    border: 1px solid black;
}

You can use substring function:

s.substring(0,s.length() - 2));

With the first 0, you say to substring that it has to start in the first character of your string and with the s.length() - 2 that it has to finish 2 characters before the String ends.

For more information about substring function you can see here:

http://docs.oracle.com/javase/7/docs/api/java/lang/String.html

Bottom line: A module is a cross between a static/utility class and a mixin.

Mixins are reusable pieces of "partial" implementation, that can be combined (or composed) in a mix & match fashion, to help write new classes. These classes can additionally have their own state and/or code, of course.

If you are using PHP, the best way is to control it the .htaccess, you need to put your files, images and videos under consideration in a separate folder/directory, and create a new .htaccess file in this directory with the below:

RewriteEngine On
RewriteCond %{REQUEST_URI} \.(mp4|mp3|avi)$ [NC]
RewriteCond %{HTTP_REFERER} !^http://sample.com/.*$ [NC]
RewriteRule ^.* - [F,L]

The first line %{REQUEST_URI} will prevent getting the file through the web browser or through curl. The second line %{HTTP_REFERER} will prevent accessing the image/video using HTML tags <img> or <video> from any website except the exception ! you provide instead of http://sample.com/ which usually should be your website itself.

This error occurs only on Windows machine with Ruby 2.0.0 version. Until we officially support Ruby 2.0 please downgrade to Ruby 1.9.

On Windows, you can install Ruby 1.9.3 alongside 2.0. Change your %PATH% to c:\ruby193\ or whatever directory you installed to prior to installing the gem.

Take a look at this tutorial for how to use SQL inside VBA:

http://www.ehow.com/how_7148832_access-vba-query-results.html

For a query that won't return results, use (reference here):

DoCmd.RunSQL

For one that will, use (reference here):

Dim dBase As Database
dBase.OpenRecordset

Following up to @steven-anderson you can also configure passwords inside the ant.properties, so the process can be fully automated

so if you put in platform\android\ant.properties the following

key.store=../../yourCertificate.jks
key.store.password=notSoSecretPassword
key.alias=userAlias
key.alias.password=notSoSecretPassword

You could wait jobs to finish on a certain interval:

int maxSecondsPerComputeDTask = 20;
try {
    while (!es.awaitTermination(uniquePhrases.size() * maxSecondsPerComputeDTask, TimeUnit.SECONDS)) {
        // consider giving up with a 'break' statement under certain conditions
    }
} catch (InterruptedException e) {
    throw new RuntimeException(e);    
}

Or you could use ExecutorService.submit(Runnable) and collect the Future objects that it returns and call get() on each in turn to wait for them to finish.

ExecutorService es = Executors.newFixedThreadPool(2);
Collection<Future<?>> futures = new LinkedList<<Future<?>>();
for (DataTable singleTable : uniquePhrases) {
    futures.add(es.submit(new ComputeDTask(singleTable)));
}
for (Future<?> future : futures) {
   try {
       future.get();
   } catch (InterruptedException e) {
       throw new RuntimeException(e);
   } catch (ExecutionException e) {
       throw new RuntimeException(e);
   }
}

InterruptedException is extremely important to handle properly. It is what lets you or the users of your library terminate a long process safely.

In a single line of code:

bool bVal = Convert.ToBoolean(Convert.ToInt16(returnValue))

No-one's mentioned gsub, which lets you do this concisely.

string.gsub(/^([a-z])/) { $1.capitalize }

Example:

 > 'caps lock must go'.gsub(/^(.)/) { $1.capitalize }
=> "Caps lock must go"

I have faced The same problem So I used the Git directly to push the project to GitHub.

In your android studio

Go to VCS=>Git=> Push: use the Branch Name You Commit and hit Push Button

Note: tested for android studio version 3.3

In order to determine the aspect ratio, you need to have a ratio to aim for.

function getHeight(length, ratio) {
  var height = ((length)/(Math.sqrt((Math.pow(ratio, 2)+1))));
  return Math.round(height);
}

function getWidth(length, ratio) {
  var width = ((length)/(Math.sqrt((1)/(Math.pow(ratio, 2)+1))));
  return Math.round(width);
}

In this example I use 16:10 since this the typical monitor aspect ratio.

var ratio = (16/10);
var height = getHeight(300,ratio);
var width = getWidth(height,ratio);

console.log(height);
console.log(width);

Results from above would be 147 and 300

No view engine is necessary, if you want to use angular with simple plain html file. Here's how to do it: In your route.js file:

router.get('/', (req, res) => {
   res.sendFile('index.html', {
     root: 'yourPathToIndexDirectory'
   });
});

If you need to pretty print an array of arrays, something like this could work: Pretty Print Array of Arrays in .NET C#

public string PrettyPrintArrayOfArrays(int[][] arrayOfArrays)
{
  if (arrayOfArrays == null)
    return "";

  var prettyArrays = new string[arrayOfArrays.Length];

  for (int i = 0; i < arrayOfArrays.Length; i++)
  {
    prettyArrays[i] = "[" + String.Join(",", arrayOfArrays[i]) + "]";
  }

  return "[" + String.Join(",", prettyArrays) + "]";
}

Example Output:

[[2,3]]

[[2,3],[5,4,3]]

[[2,3],[5,4,3],[8,9]]

Quick compatibility build script (also works on Windows):

"build": "react-scripts build && rm -rf docs && mv build docs"

Two options:

for (let item in MotifIntervention) {
    if (isNaN(Number(item))) {
        console.log(item);
    }
}

Or

Object.keys(MotifIntervention).filter(key => !isNaN(Number(MotifIntervention[key])));

(code in playground)

Edit

String enums look different than regular ones, for example:

enum MyEnum {
    A = "a",
    B = "b",
    C = "c"
}

Compiles into:

var MyEnum;
(function (MyEnum) {
    MyEnum["A"] = "a";
    MyEnum["B"] = "b";
    MyEnum["C"] = "c";
})(MyEnum || (MyEnum = {}));

Which just gives you this object:

{
    A: "a",
    B: "b",
    C: "c"
}

You can get all the keys (["A", "B", "C"]) like this:

Object.keys(MyEnum);

And the values (["a", "b", "c"]):

Object.keys(MyEnum).map(key => MyEnum[key])

Or using Object.values():

Object.values(MyEnum)

Use a controller method if you need to run arbitrary JavaScript code, or you could define a filter that returned true or false.

I just tested (should have done that first), and something like ng-show="!a && b" worked as expected.

I can't comment up thread due to lack of rep. Another commenter stated they couldn't migrate from a lower version to a higher version of IIS. This is true if you don't merge some files, but if you do you can as I just migrated my IIS 7.5 site to IIS 8.0 using the answer posted by chews.

When the export is created (II7.5), there are two key files (administration.config and applicationHost.config) which have references to resources on the IIS7.5 server. For example, a DLL will be referred with a public key and version specific to 7.5. These are NOT the same on the IIS8 server. The feature configuration may differ as well (I ensured mine were identical). There are some new features in 8 which will never exist in 7.5.

If you are brave enough to merge the two files - it will work. I had to uninstall IIS once because I messed it up, but got it the second time.

I used a merge tool (Beyond Compare) and without something equivalent it would be a huge PITA - but was pretty easy with a good diff tool (five minutes).

To do the merge, the 8.0 files need to be diffed against the exported 7.5 files BEFORE an import is attempted. For the most part, the 8.0 files need to overwrite the server specific stuff in the exported 7.5 files, while leaving the site/app pool specific stuff.

I found that administration.config was almost identical, sans the version info of many entries. This one was easy.

The applicationHost.config has a lot more differences. Some entries are ordered differently, but otherwise identical, so you will have to pick through each difference and figure it out.

I put my 7.5 export files in the System32\inetsrv\config\Export folder prior to merging.

I merged FROM folder System32\inetsrv\config to folder System32\inetsrv\config\Export for both files I mentioned above. I pushed over everything in the FROM files except site specific tags/elements (e.g. applicationPools, customMetadata, sites, authentication). Of special note, there were also many site specific "location" tag blocks that I had to keep, but the new server had its own "location" tag block with server specific defaults that has to be kept.

Lastly, do note that if you use service accounts, these cached passwords are junk and will have to be re-entered for your app pools. None of my sites worked initially, but all that was required was re-entering the passwords for all my app pools and I was up and running.

If someone who can comment mention this post down thread - it will probably help someone else like me who has many sites on one server with complicated configurations.

Stuart

Just remove () at the end.

List<string> optionList = new List<string>
            { "AdditionalCardPersonAdressType", /* rest of elements */ };

<asp:FileUpload ID="FileUploadExcel" ClientIDMode="Static" runat="server" />
<asp:Button ID="btnUpload" ClientIDMode="Static" runat="server" Text="Upload Excel File" />

.

$('#btnUpload').click(function () {
    var uploadpath = $('#FileUploadExcel').val();
    var fileExtension = uploadpath.substring(uploadpath.lastIndexOf(".") + 1, uploadpath.length);

    if ($('#FileUploadExcel').val().length == 0) {
        // write error message
        return false;
    }

    if (fileExtension == "xls" || fileExtension == "xlsx") {
        //write code for success
    }
    else {
        //error code - select only excel files
        return false;
    }

});

SELECT * FROM Table_name Where Month(date)='10' && YEAR(date)='2016';

Putting plot.tight_layout() after all changes on the graph, just before show() or savefig() will solve the problem.

Keep in mind you'll also have to give the IUSR account write access for the folder once you upload to your web server.

Personally I recommend not allowing write access to the root folder unless you have a good reason for doing so. And then you need to be careful what sort of files you allow to be saved so you don't inadvertently allow someone to write their own ASPX pages.

If you want to declare the dictionary once and never change it then declare it as readonly:

private static readonly Dictionary<string, string> ErrorCodes
    = new Dictionary<string, string>
{
    { "1", "Error One" },
    { "2", "Error Two" }
};

If you want to dictionary items to be readonly (not just the reference but also the items in the collection) then you will have to create a readonly dictionary class that implements IDictionary.

Check out ReadOnlyCollection for reference.

BTW const can only be used when declaring scalar values inline.

This is an addendum to @endy-tjahjono's solution.

I ended up not being able to get the value of uploadme from the scope. Even though uploadme in the HTML was visibly updated by the directive, I could still not access its value by $scope.uploadme. I was able to set its value from the scope, though. Mysterious, right..?

As it turned out, a child scope was created by the directive, and the child scope had its own uploadme.

The solution was to use an object rather than a primitive to hold the value of uploadme.

In the controller I have:

$scope.uploadme = {};
$scope.uploadme.src = "";

and in the HTML:

 <input type="file" fileread="uploadme.src"/>
 <input type="text" ng-model="uploadme.src"/>

There are no changes to the directive.

Now, it all works like expected. I can grab the value of uploadme.src from my controller using $scope.uploadme.

Well, it depends on your needs. Very often I keep my references to widgets in activity (as a class fields) - and set them in onCreate method. I think that is a good idea
Probably the reason for your nulls is that you are trying to call findViewById() before you set contentView() in your onCreate() method - please check that.

For Python versions in 2.6+ and 3.x

You can use the str.format method. Examples:

>>> print('{0:.16f}'.format(1.6))
1.6000000000000001

>>> print('{0:.15f}'.format(1.6))
1.600000000000000

Note the 1 at the end of the first example is rounding error; it happens because exact representation of the decimal number 1.6 requires an infinite number binary digits. Since floating-point numbers have a finite number of bits, the number is rounded to a nearby, but not equal, value.

For Python versions prior to 2.6 (at least back to 2.0)

You can use the "modulo-formatting" syntax (this works for Python 2.6 and 2.7 too):

>>> print '%.16f' % 1.6
1.6000000000000001

>>> print '%.15f' % 1.6
1.600000000000000

U use the following class to solve this problem;

.custom-image{height: auto; width: auto; max-height: 100%; max-width: 100%; object-fit: contain;}

You really can't display 3 columns of data as a 'surface'. Only having one column of 'Z' data will give you a line in 3 dimensional space, not a surface (Or in the case of your data, 3 separate lines). For Excel to be able to work with this data, it needs to be formatted as shown below:

      13    21   29      37    45   
1000  75.2                              
1000       79.21                            
1000             80.02                      
5000             87.9                   
5000                    88.54               
5000                           88.56            
10000            90.11      
10000                   90.79   
10000                          90.87

Then, to get an actual surface, you would need to fill in all the missing cells with the appropriate Z-values. If you don't have those, then you are better off showing this as 3 separate 2D lines, because there isn't enough data for a surface.

The best 3D representation that Excel will give you of the above data is pretty confusing:

Representing this limited dataset as 2D data might be a better choice:

As a note for future reference, these types of questions usually do a little better on superuser.com.
