Backing-Bean

   List<SelectItem> names = new ArrayList<SelectItem>();

   //-- Populate list from database

   names.add(new SelectItem(valueObject,"label"));

To display particular selected record, it must be one of the values in the list.

If you are using ASP.NET Identity UserManager you can get it like this as well:

var userManager = Request.GetOwinContext().GetUserManager<ApplicationUserManager>();

var roles = userManager.GetRoles(User.Identity.GetUserId());

If you have changed key for user from Guid to Int for example use this code:

var roles = userManager.GetRoles(User.Identity.GetUserId<int>());

Google's Guava library provides a nice helper method to do this: Doubles.tryParse(String). You use it like Double.parseDouble but it returns null rather than throwing an exception if the string does not parse to a double.

Try this:

Dim myarray As Variant
myarray = Array("Cat", "Dog", "Rabbit")

Here is one way of getting the design that you want.

Start with the following HTML:

<div class="container">
    <div class="row-fluid">
        <div class="span12">
            <div class="nav">nav area</div>
            <div class="bg-image">
                <img src="http://unplugged.ee/wp-content/uploads/2013/03/frank2.jpg">
                 <h1>This is centered text.</h1>
            </div>
            <div class="main">main area</div>
        </div>
    </div>
</div>

Note that the background image is now part of the regular flow of the document.

Apply the following CSS:

.bg-image {
    position: relative;
}
.bg-image img {
    display: block;
    width: 100%;
    max-width: 1200px; /* corresponds to max height of 450px */
    margin: 0 auto;
}
.bg-image h1 {
    position: absolute;
    text-align: center;
    bottom: 0;
    left: 0;
    right: 0;
    color: white;
}
.nav, .main {
    background-color: #f6f6f6;
    text-align: center;
}

How This Works

The image is set an regular flow content with a width of 100%, so it will adjust itself responsively to the width of the parent container. However, you want the height to be no more than 450px, which corresponds to the image width of 1200px, so set the maximum width of the image to 1200px. You can keep the image centered by using display: block and margin: 0 auto.

The text is painted over the image by using absolute positioning. In the simplest case, I stretch the h1 element to be the full width of the parent and use text-align: center to center the text. Use the top or bottom offsets to place the text where it is needed.

If your banner images are going to vary in aspect ratio, you will need to adjust the maximum width value for .bg-image img dynamically using jQuery/Javascript, but otherwise, this approach has a lot to offer.

A colleague asked me how to open A LOT of ssh sessions at once. I used cobbal's answer to write this script:

tmpdir=$( mktemp -d )
trap '$DEBUG rm -rf $tmpdir ' EXIT
index=1

{
cat <<COMMANDS
ssh user1@host1
ssh user2@host2
COMMANDS
} | while read command
do 
  COMMAND_FILE=$tmpdir/$index.command
  index=$(( index + 1 ))
  echo $command > $COMMAND_FILE
  chmod +x  $COMMAND_FILE
  open $COMMAND_FILE
done
sleep 60

By updating the list of commands ( they don't have to be ssh invocations ), you will get an additional open window for every command executed. The sleep 60 at the end is there to keep the .command files around while they are being executed. Otherwise, the shell completes too quickly, executing the trap to delete the temp directory ( created by mktemp ) before the launched sessions have an opportunity to read the files.

If you are using -o (or -a), it needs to be inside the brackets of the test command:

if [ "$age" -le "7" -o "$age" -ge " 65" ]

However, their use is deprecated, and you should use separate test commands joined by || (or &&) instead:

if [ "$age" -le "7" ] || [ "$age" -ge " 65" ]

Make sure the closing brackets are preceded with whitespace, as they are technically arguments to [, not simply syntax.

In bash and some other shells, you can use the superior [[ expression as shown in kamituel's answer. The above will work in any POSIX-compliant shell.

There is a module datetime_truncate which handlers this for you. It just calls datetime.replace.

I solved this problem with a directive that basicly what it does is to bind the real ng-model on a special attribute which I watch in the directive, then using a debounce service I update my directive attribute, so the user watch on the variable that he bind to debounce-model instead of ng-model.

.directive('debounceDelay', function ($compile, $debounce) {
return {
  replace: false,
  scope: {
    debounceModel: '='
  },
  link: function (scope, element, attr) {
    var delay= attr.debounceDelay;
    var applyFunc = function () {
      scope.debounceModel = scope.model;
    }
    scope.model = scope.debounceModel;
    scope.$watch('model', function(){
      $debounce(applyFunc, delay);
    });
    attr.$set('ngModel', 'model');
    element.removeAttr('debounce-delay'); // so the next $compile won't run it again!

   $compile(element)(scope);
  }
};
});

Usage:

<input type="text" debounce-delay="1000" debounce-model="search"></input>

And in the controller :

    $scope.search = "";
    $scope.$watch('search', function (newVal, oldVal) {
      if(newVal === oldVal){
        return;
      }else{ //do something meaningful }

Demo in jsfiddle: http://jsfiddle.net/6K7Kd/37/

I have found the solution in spring boot by using @CrossOrigin annotation.

@RestController
@CrossOrigin
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**");
    }
}

Well, I think it would be a bad idea to replicate the code which is already present in classes like SimpleDateFormat.

On the other hand, personally I'd suggest avoiding Calendar and Date entirely if you can, and using Joda Time instead, as a far better designed date and time API. For example, you need to be aware that SimpleDateFormat is not thread-safe, so you either need thread-locals, synchronization, or a new instance each time you use it. Joda parsers and formatters are thread-safe.

If you want the cells to resize depending on the content, then you must not specify a width to the table, the rows, or the cells.

If you don't want word wrap, assign the CSS style white-space: nowrap to the cells.

Here's a shell script that does it without calling other programs:

#! /bin/env bash 

#bash script to find the relative path between two directories

mydir=${0%/}
mydir=${0%/*}
creadlink="$mydir/creadlink"

shopt -s extglob

relpath_ () {
        path1=$("$creadlink" "$1")
        path2=$("$creadlink" "$2")
        orig1=$path1
        path1=${path1%/}/
        path2=${path2%/}/

        while :; do
                if test ! "$path1"; then
                        break
                fi
                part1=${path2#$path1}
                if test "${part1#/}" = "$part1"; then
                        path1=${path1%/*}
                        continue
                fi
                if test "${path2#$path1}" = "$path2"; then
                        path1=${path1%/*}
                        continue
                fi
                break
        done

        if test ! "$path1"; then
                path1=.
        fi
        printf "$path1"

}

relpath_test () {

Just came up with this:

set sString=" hello|123(4) "
call :trimMENew %sString%
echo "%sString%"
exit /b 0

:trimMeNew
set "sString=%~1"
if "%sString:~0,1%" == " " set "sString=%sString:~1%"
if "%sString:~-1%" == " " set "sString=%sString:~0,-1%"
exit /b 0

Facing the very same problem (avoiding the default path in a network) I came up to this solution with the hints given in other answers.

The solution is editing the Rprofile file to overwrite the variable R_LIBS_USER which by default points to the home directory.

Here the steps:

1. Create the target destination folder for the libraries, e.g., ~\target.
2. Find the Rprofile file. In my case it was at C:\Program Files\R\R-3.3.3\library\base\R\Rprofile.
3. Edit the file and change the definition the variable R_LIBS_USER. In my case, I replaced the this line file.path(Sys.getenv("R_USER"), "R", with file.path("~\target", "R",.

The documentation that support this solution is here

Original file with:

 if(!nzchar(Sys.getenv("R_LIBS_USER")))
     Sys.setenv(R_LIBS_USER=
                file.path(Sys.getenv("R_USER"), "R",
                          "win-library",
                          paste(R.version$major,
                                sub("\\..*$", "", R.version$minor),
                                sep=".")
                          )) 

Modified file:

if(!nzchar(Sys.getenv("R_LIBS_USER")))
     Sys.setenv(R_LIBS_USER=
                file.path("~\target", "R",
                          "win-library",
                          paste(R.version$major,
                                sub("\\..*$", "", R.version$minor),
                                sep=".")
                          ))

Look for keys (first word of line) in file2 that are also in file1.
Step 1: fill array a with the first words of file 1:

awk '{a[$1];}' file1

Step 2: Fill array a and ignore file 2 in the same command. For this check the total number of records until now with the number of the current input file.

awk 'NR==FNR{a[$1]}' file1 file2

Step 3: Ignore actions that might come after } when parsing file 1

awk 'NR==FNR{a[$1];next}' file1 file2 

Step 4: print key of file2 when found in the array a

awk 'NR==FNR{a[$1];next} $1 in a{print $1}' file1 file2

git checkout -f

must work, if your previous state is clean.

The simplest choice I found to solve this problem was using the python lib called networkx.

It implements the Johnson's algorithm mentioned in the best answer of this question but it makes quite simple to execute.

In short you need the following:

import networkx as nx
import matplotlib.pyplot as plt

# Create Directed Graph
G=nx.DiGraph()

# Add a list of nodes:
G.add_nodes_from(["a","b","c","d","e"])

# Add a list of edges:
G.add_edges_from([("a","b"),("b","c"), ("c","a"), ("b","d"), ("d","e"), ("e","a")])

#Return a list of cycles described as a list o nodes
list(nx.simple_cycles(G))

Answer: [['a', 'b', 'd', 'e'], ['a', 'b', 'c']]

You could have multiple Python versions on your macOS.

You may check that by command, type or which command, like:

which -a python python2 python2.7 python3 python3.6

Or type python in Terminal and hit Tab few times for auto completion, which is equivalent to:

compgen -c python

By default python/pip commands points to the first binary found in PATH environment variable depending what's actually installed. So before installing Python packages with Homebrew, the default Python is installed in /usr/bin which is shipped with your macOS (e.g. Python 2.7.10 on High Sierra). Any versions found in /usr/local (such as /usr/local/bin) are provided by external packages.

It is generally advised, that when working with multiple versions, for Python 2 you may use python2/pip2 command, respectively for Python 3 you can use python3/pip3, but it depends on your configuration which commands are available.

It is also worth to mention, that since release of Homebrew 1.5.0+ (on 19 January 2018), the python formula has been upgraded to Python 3.x and a python@2 formula will be added for installing Python 2.7. Before, python formula was pointing to Python 2.

For instance, if you've installed different version via Homebrew, try the following command:

brew list python python3

or:

brew list | grep ^python

it'll show you all Python files installed with the package.

Alternatively you may use apropos or locate python command to locate more Python related files.

To check any environment variables related to Python, run:

env | grep ^PYTHON

To address your issues:

• Error: No such keg: /usr/local/Cellar/python

  Means you don't have Python installed via Homebrew. However double check by specifying only one package at a time (like brew list python python2 python3).

• The locate database (/var/db/locate.database) does not exist.

  Follow the advice and run:

  sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.locate.plist
  

  After the database is rebuild, you can use locate command.

Some times you may make silly mistakes like writing insert query on the same .sql file (in the same workspace/tab) so once you execute the insert query where your create query was written just above and already executed, it will again start executing along with the insert query.

This is the reason why we are getting the object name (table name) exists already, since it's getting executed for the second time.

So go to a separate tab to write the insert or drop or whatever queries you are about to execute.

Or else use comment lines preceding all queries in the same workspace like

CREATE -- …
-- Insert query
INSERT INTO -- …

If you just use inline svg there is no problem.

<svg id="svg1" xmlns="http://www.w3.org/2000/svg" style="width: 3.5in; height: 1in">_x000D_
  <circle id="circle1" r="30" cx="34" cy="34" onclick="circle1.style.fill='yellow';"_x000D_
            style="fill: red; stroke: blue; stroke-width: 2"/>_x000D_
  </svg>_x000D_
  

from __future__ import with_statement
with open('file.txt','r+') as f:
    counter = str(int(f.read().strip())+1)
    f.seek(0)
    f.write(counter)

On @Sorin's suggestion of the Java Pattern docs, it looks like chars to escape are at least:

\.[{(*+?^$|

My issue was very simple, the working directory was not the "Source" directory that was printed when the file ran. To fix this, you can use getwd() and setwd() to get your relative links working, or just use a full path when opening the csv.

print(getwd()) # Where does the code think it is?
setwd("~/Documents") # Where do I want my code to be?
dat = read.csv("~/Documents/Data Visualization/expDataAnalysis/one/ac1_survey.csv") #just make it work!

The answer seems to be just no.

Although there are many good other answers, they either just hide the uglyness (which I did not ask for) or introduce new problems (edge cases).

You could use

https://github.com/slightfoot/flutter_after_layout

which executes a function only one time after the layout is completed. Or just look at its implementation and add it to your code :-)

Which is basically

  void initState() {
    super.initState();
    WidgetsBinding.instance
        .addPostFrameCallback((_) => yourFunction(context));
  }

I had the same $count variable in a while loop getting lost issue.

@fedorqui's answer (and a few others) are accurate answers to the actual question: the sub-shell is indeed the problem.

But it lead me to another issue: I wasn't piping a file content... but the output of a series of pipes & greps...

my erroring sample code:

count=0
cat /etc/hosts | head | while read line; do
  ((count++))
  echo $count $line
done
echo $count

and my fix thanks to the help of this thread and the process substitution:

count=0
while IFS= read -r line; do
  ((count++))
  echo "$count $line"
done < <(cat /etc/hosts | head)
echo "$count"

All the modern browsers provides you storage apis. You can use them (localStorage or sessionStorage) to save your data.

All you have to do is after receiving the response store it to browser storage. Then next time you find the same call, search if the response is saved already. If yes, return the response from there; if not make a fresh call.

Smartjax plugin also does similar things; but as your requirement is just saving the call response, you can write your code inside your jQuery ajax success function to save the response. And before making call just check if the response is already saved.

<ul class="icons-ul">
<li><i class="icon-play-sign"></i> <a>option</a></li>
<li><i class="icon-play-sign"></i> <a>option</a></li>

<li><i class="icon-play-sign"></i> <a>option</a></li>
<li><i class="icon-play-sign"></i> <a>option</a></li>
</ul>

All the font awesome icons comes default with Bootstrap.

There is no such keyword "atomic"

@property(atomic, retain) UITextField *userName;

We can use the above like

@property(retain) UITextField *userName;

See Stack Overflow question I am getting issues if I use @property(atomic,retain)NSString *myString.

clearfix should contain the floating elements but in your html you have added clearfix only after floating right that is your pull-right so you should do like this:

<div class="clearfix">
  <div id="sidebar">
    <ul>
      <li>A</li>
      <li>A</li>
      <li>C</li>
      <li>D</li>
      <li>E</li>
      <li>F</li>
      <li>...</li>
      <li>Z</li>
    </ul>
  </div>
  <div id="main">
    <div>
      <div class="pull-right">
        <a>RIGHT</a>
      </div>
    </div>
  <div>MOVED BELOW Z</div>
</div>

see this demo

Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden; as you have done in your main.

//form/descendant::input[@type='submit']

Check if /usr/bin has 'javac'. If not you have installed JRE & have to install jdk dev version like "java-1.8.0-openjdk-devel.x86_64"

Here is a quick console app to depict the concept of how to solve your issue.

You can use deparse and substitute to get the name of a function argument:

myfunc <- function(v1) {
  deparse(substitute(v1))
}

myfunc(foo)
[1] "foo"

This will give you lines 1 to 20000 in newfile1.csv
and lines 20001 to the end in file newfile2.csv

It overcomes the 8K character limit per line too.

This uses a helper batch file called findrepl.bat from - https://www.dropbox.com/s/rfdldmcb6vwi9xc/findrepl.bat

Place findrepl.bat in the same folder as the batch file or on the path.

It's more robust than a plain batch file, and quicker too.

findrepl /o:1:20000 <file.csv >newfile1.csv
findrepl /o:20001   <file.csv >newfile2.csv

I have just found ActiveSharp - Automatic INotifyPropertyChanged, I have yet to use it, but it looks good.

To quote from it's web site...

Send property change notifications without specifying property name as a string.

Instead, write properties like this:

public int Foo
{
    get { return _foo; }
    set { SetValue(ref _foo, value); }  // <-- no property name here
}

Note that there is no need to include the name of the property as a string. ActiveSharp reliably and correctly figures that out for itself. It works based on the fact that your property implementation passes the backing field (_foo) by ref. (ActiveSharp uses that "by ref" call to identify which backing field was passed, and from the field it identifies the property).

I found the root cause of this (we got both "adding window failed" and file descriptor leak as mvds says).

There is a bug in BitmapFactory.decodeFileDescriptor() of Android 4.4. It only occurs when inPurgeable and inInputShareable of BitmapOptions are set to true. This causes many problem in many places interact with files.

Note that the method is also called from MediaStore.Images.Thumbnails.getThumbnail().

Universal Image Loader is affected by this issue. Picasso and Glide seems to be not affected. https://github.com/nostra13/Android-Universal-Image-Loader/issues/1020

You can avoid confliction like this

var jq=jQuery.noConflict();
jq(document).ready(function(){  
  alert("Hi this will not conflict now");
  jq('selector').show();
});

According to the documentation the related method to android:backgroundTint is setBackgroundTintList(ColorStateList list)

Update

Follow this link to know how create a Color State List Resource.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:color="#your_color_here" />
</selector>

then load it using

setBackgroundTintList(contextInstance.getResources().getColorStateList(R.color.your_xml_name));

where contextInstance is an instance of a Context

using AppCompart

btnTag.setSupportButtonTintList(ContextCompat.getColorStateList(Activity.this, R.color.colorPrimary));

It works for me, by using double quotes around variables.

thank you @thierry-templier!

The closures are a way to execute code in the context it was created in.

What this means for concurency is that you can define variables, then initiate a nonblocking I/O function, and send it an anonymous function for its callback.

When the task is complete, the callback function will execute in the context with the variables, this is the closure.

The reason closures are so good for writing applications with nonblocking I/O is that it's very easy to manage the context of functions executing asynchronously.

My environment was prior tooling such as Jenkins and was running with batch files (I know, I'm old). So those batch files (and their sub-batch files) are using environment variables. This was my piece of groovy script which injects environment variables. The names and parameters used are dummy ones.

// The process/batch which uses environment variables
def buildLabel = "SomeVersionNr"
def script = "startBuild.bat"
def processBuilder = new ProcessBuilder(script, buildLabel)

//Inject our environment variables
Map<String, String> env = processBuilder.environment()
env.put("ProjectRoot", "someLocation")
env.put("SomeVar", "Some")

Process p = processBuilder.start()
p.waitFor()

Of course if you set Jenkins up from scratch you would probably do it differently and share the variables in another way, or pass parameters around but this might come handy.

Let me explain the difference between process and threads first.

A process can have {1..N} number of threads. A small explanation on virtual memory and virtual processor.

Virtual memory

Used as a swap space so that a process thinks that it is sitting on the primary memory for execution.

Virtual processor

The same concept as virtual memory except this is for processor. To a process, it will look it's the only thing that is using the processor.

OS will take care of allocating the virtual memory and virtual processor to a process and performing the swap between processes and doing execution.

All the threads within a process will share the same virtual memory. But, each thread will have their individual virtual processor assigned to them so that they can be executed individually.

Thus saving the memory as well as utilizing the CPU to its potential.

It doesn't work in IE5, but that's not a big issue.

However, cacheing headers are unreliable in meta elements; for one, any web proxies between the site and the user will completely ignore them. You should always use a real HTTP header for headers such as Cache-Control and Pragma.

Answer (Basic is advance!):

Error: 10060 Adding a timeout parameter to request solved the issue for me.

Example 1

import urllib
import urllib2
g = "http://www.google.com/"
read = urllib2.urlopen(g, timeout=20)

Example 2

A similar error also occurred while I was making a GET request. Again, passing a timeout parameter solved the 10060 Error.

response = requests.get(param_url, timeout=20)

As said earlier, your code will work unless you have the same classes loaded on two different class loaders. This might happen in case you need multiple versions of the same class in memory at the same time, or you are doing some weird on the fly compilation stuff (as I am).

In this case, if you want to consider these as the same class (which might be reasonable depending on the case), you can match their names to compare them.

public static boolean areClassesQuiteTheSame(Class<?> c1, Class<?> c2) {
  // TODO handle nulls maybe?
  return c1.getCanonicalName().equals(c2.getCanonicalName());
}

Keep in mind that this comparison will do just what it does: compare class names; I don't think you will be able to cast from one version of a class to the other, and before looking into reflection, you might want to make sure there's a good reason for your classloader mess.

In matplotlib 2.0 there is a parameter called fillstyle which allows better control on the way markers are filled. In my case I have used it with errorbars but it works for markers in general http://matplotlib.org/api/_as_gen/matplotlib.axes.Axes.errorbar.html

fillstyle accepts the following values: [‘full’ | ‘left’ | ‘right’ | ‘bottom’ | ‘top’ | ‘none’]

There are two important things to keep in mind when using fillstyle,

1) If mfc is set to any kind of value it will take priority, hence, if you did set fillstyle to 'none' it would not take effect. So avoid using mfc in conjuntion with fillstyle

2) You might want to control the marker edge width (using markeredgewidth or mew) because if the marker is relatively small and the edge width is thick, the markers will look like filled even though they are not.

Following is an example using errorbars:

myplot.errorbar(x=myXval, y=myYval, yerr=myYerrVal, fmt='o', fillstyle='none', ecolor='blue',  mec='blue')

I guess you could use a background-image that contains the word "password" and change it back to an empty background-image on .focus().

.blur() ----> image with "password"

.focus() -----> image with no "password"

You could also do it with some CSS and jQuery. Have a text field show up exactly on top of the password field, hide() is on focus() and focus on the password field...

To build and install modern Git on CentOS 6:

yum install -y curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker
export GIT_VERSION=2.6.4
mkdir /root/git
cd /root/git
wget "https://www.kernel.org/pub/software/scm/git/git-${GIT_VERSION}.tar.gz"
tar xvzf "git-${GIT_VERSION}.tar.gz"
cd git-${GIT_VERSION}
make prefix=/usr/local all
make prefix=/usr/local install
yum remove -y git
git --version # should be GIT_VERSION

This was the solution that worked for me since I couldn't find 'Common Properties' option.

1. Select your topmost level project in Solution Explorer.

2. Go to Project, and in contextual menu Set as StartUp Project.

I came up with the solution and posted it on my blog

http://web.archive.org/web/20130310123646/http://onlinemarketingexperts.com.au/2013/01/how-to-permanently-redirect-301-all-404-missing-pages-in-htaccess/

here is the htaccess code also

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . / [L,R=301]

but I posted other solutions on my blog too, it depends what you need really

the correct way to do will be as following in the old-style classes which doesn't inherit from 'object'

class A:
    def foo(self):
        return "Hi there"

class B(A):
    def foo(self, name):
        return A.foo(self) + name

Use a comma to specify two (or more) different rules:

@media screen and (max-width: 995px), 
       screen and (max-height: 700px) {
  ...
}

From https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries

Commas are used to combine multiple media queries into a single rule. Each query in a comma-separated list is treated separately from the others. Thus, if any of the queries in a list is true, the entire media statement returns true. In other words, lists behave like a logical or operator.

In Sqlite:

CREATE TABLE T AS
SELECT * FROM ...;
-- Use temporary table `T`
DROP TABLE T;

To check if a string is just a spaces or newline

Use this simple code

mystr = "      \n  \r  \t   "
if not mystr.strip(): # The String Is Only Spaces!
    print("\n[!] Invalid String !!!")
    exit(1)
mystr = mystr.strip()
print("\n[*] Your String Is: "+mystr)

You can retrieve all of the Map's keys using the method keySet(). Now, if what you need is to get a key given its value, that's an entirely different matter and Map won't help you there; you'd need a specialized data structure, like BidiMap (a map that allows bidirectional lookup between key and values) from Apache's Commons Collections - also be aware that several different keys could be mapped to the same value.

Just one more line for @tofutim answer ... if you want custom field name for concatenated row ...

SELECT 
  (
    col1 || '-' || SUBSTR('00' || col2, -2, 2) | '-' || SUBSTR('0000' || col3, -4, 4)
  ) AS my_column 
FROM
  mytable;

Tested on SQLite 3.8.8.3, Thanks!

? PERFORMANCE SOLUTION ?

If you care about performance and micro-optimizations check this one-liner:

function no_dupes(array $input_array) {
    return count($input_array) === count(array_flip($input_array));
}

Description:

Function compares number of array elements in $input_array with array_flip'ed elements. Values become keys and guess what - keys must be unique in associative arrays so not unique values are lost and final number of elements is lower than original.

As said in manual array keys can be only type of int or string so this is what you can have in original array values to compare, otherwise PHP will start casting with unexpected results.

Create xml file like edit_text_design.xml and save it to your drawable folder

i have given the Color codes According to my Choice, Please Change Color Codes As per your Choice !

 <?xml version="1.0" encoding="utf-8"?>
  <layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

<item>
    <shape>
        <solid android:color="#c2c2c2" />
    </shape>
</item>

<!-- main color -->
<item
    android:bottom="1.5dp"
    android:left="1.5dp"
    android:right="1.5dp">
    <shape>
        <solid android:color="#000" />
    </shape>
</item>

<!-- draw another block to cut-off the left and right bars -->
<item android:bottom="5.0dp">
    <shape>
        <solid android:color="#000" />
    </shape>
</item>

</layer-list>

your Edit Text Should contain it as Background :

add android:background="@drawable/edit_text_design" to all of your EditText's

and your above EditText should now look like this:

      <EditText
        android:id="@+id/name_edit_text"
        android:background="@drawable/edit_text_design"
        android:layout_width="wrap_content"

WAR file is just a JAR file, to extract it, just issue following jar command –

jar -xvf yourWARfileName.war

If the jar command is not found, which sometimes happens in the Windows command prompt, then specify full path i.e. in my case it is,

 c:\java\jdk-1.7.0\bin\jar -xvf my-file.war

For everyone if you still strugle with Refusing connection, here is my advice. Download XAMPP or other similar sw and just start MySQL. You dont have to run apache or other things just the MySQL.

I search the source code inside of Github Repositories with the free Sourcegraph Chrome Extension ... But I Downloaded Chrome First, I knew other browsers support it though, such as - and maybe just only - Firefox.

I skimmed through SourceForge's Chrome Extension Docs and then also I looked at just what I needed for searching for directory names with Github's Search Engine itself, by reading some of Github's Codebase Searching Doc

You could try using Caesar.

First option:

byte[] hash =
    new Hash(
        new ImmutableMessageDigest(
            MessageDigest.getInstance("MD5")
        ),
        new PlainText("String to hash...")
    ).asArray();

Second option:

byte[] hash =
    new ImmutableMessageDigest(
        MessageDigest.getInstance("MD5")
    ).update(
        new PlainText("String to hash...")
    ).digest();

Better solution for your Stack implementation

import java.util.List;
import java.util.ArrayList;
public class IntegerStack 

{

    private List<Integer> stack;

    public IntegerStack(int SIZE) 
    {
        stack = new ArrayList<Integer>(SIZE);
    }

    public void push(int i) 
    {

       stack.add(0,i);
     }

     public int pop() 
     { 
        if(!stack.isEmpty()){
           int i= stack.get(0);
           stack.remove(0);
           return i;
        } else{
           return -1;// Or any invalid value
        }
     }

     public int peek()
     {
        if(!stack.isEmpty()){
           return stack.get(0);
        } else{
           return -1;// Or any invalid value
        }
     }


     public boolean isEmpty() 
     {
       stack.isEmpty();
     }

 }

If you have to use Array... Here are problems in your code and possible solutions

import java.util.Arrays;
public class IntegerStack 
{

    private int stack [];
    private int top; 

    public IntegerStack(int SIZE) 
   {
    stack = new int [SIZE];
    top = -1; // top should be 0. If you keep it as -1, problems will arise when SIZE is passed as 0. 
    // In your push method -1==0 will be false and your code will try to add the invalid element to Stack .. 
     /**Solution top=0; */
    }

public void push(int i) 
{
    if (top == stack.length)
    {
        extendStack();
    }

       stack[top]= i;
        top++;

}

public int pop() 
{
    top --; // here you are reducing the top before giving the Object back 
   /*Solution 
      if(!isEmpty()){
      int value = stack[top];
       top --;
     return value; 
    } else{
      return -1;// OR invalid value
    }
   */
    return stack[top];
}

public int peek()
{
    return stack[top]; // Problem when stack is empty or size is 0
    /*Solution 
       if(!isEmpty()){
         return stack[top];
       }else{
         return -1;// Or any invalid value
       }
    */


}


public boolean isEmpty() 
{
    if ( top == -1); // problem... we changed top to 0 above so here it need to check if its 0 and there should be no semicolon after the if statement
   /* Solution if(top==0) */
    {
        return true;
    }
}

private void extendStack()
{

    int [] copy = Arrays.copyOf(stack, stack.length); // The second parameter in Arrays.copyOf has no changes, so there will be no change in array length.
  /*Solution  
    stack=Arrays.copyOf(stack, stack.length+1); 
   */
     }

     }

Today I also got this error Cordova : Requirements check failed for JDK 1.8 or greater in my Mac OS while build Ionic App when I run command ionic cordova build --release android via terminal.

Below command resolve my issue :-

Hope it will help someone in future!

In my case, I was running tests through MSTest and found out that I was deploying both a 32-bit and 64-bit DLL to the test directory. The program was favoring the 64-bit DLL and causing it to fail.

TL;DR Make sure you only deploy 32-bit DLLs to tests.

If you are on Mac OS X just use Simulator. I don't know if it is available by default but it looks like it is a part of the Xcode suite.

Anyway it is free and really useful, it allows you to simulate many popular Apple devices:

Python 3.6+ provides built-in convenience methods to find and decode the plain text body as in @Todor Minakov's answer. You can use the EMailMessage.get_body() and get_content() methods:

msg = email.message_from_string(s, policy=email.policy.default)
body = msg.get_body(('plain',))
if body:
    body = body.get_content()
print(body)

Note this will give None if there is no (obvious) plain text body part.

If you are reading from e.g. an mbox file, you can give the mailbox constructor an EmailMessage factory:

mbox = mailbox.mbox(mboxfile, factory=lambda f: email.message_from_binary_file(f, policy=email.policy.default), create=False)
for msg in mbox:
    ...

Note you must pass email.policy.default as the policy, since it's not the default...

For this example you will need to create your own type, that would be an array. Then you create a bigger array which elements are of type you have just created.

To run my example you will need to fill columns A and B in Sheet1 with some values. Then run test(). It will read first two rows and add the values to the BigArr. Then it will check how many rows of data you have and read them all, from the place it has stopped reading, i.e., 3rd row.

Tested in Excel 2007.

Option Explicit
Private Type SmallArr
  Elt() As Variant
End Type

Sub test()
    Dim x As Long, max_row As Long, y As Long
    '' Define big array as an array of small arrays
    Dim BigArr() As SmallArr
    y = 2
    ReDim Preserve BigArr(0 To y)
    For x = 0 To y
        ReDim Preserve BigArr(x).Elt(0 To 1)
        '' Take some test values
        BigArr(x).Elt(0) = Cells(x + 1, 1).Value
        BigArr(x).Elt(1) = Cells(x + 1, 2).Value
    Next x
    '' Write what has been read
    Debug.Print "BigArr size = " & UBound(BigArr) + 1
    For x = 0 To UBound(BigArr)
        Debug.Print BigArr(x).Elt(0) & " | " & BigArr(x).Elt(1)
    Next x
    '' Get the number of the last not empty row
    max_row = Range("A" & Rows.Count).End(xlUp).Row

    '' Change the size of the big array
    ReDim Preserve BigArr(0 To max_row)

    Debug.Print "new size of BigArr with old data = " & UBound(BigArr)
    '' Check haven't we lost any data
    For x = 0 To y
        Debug.Print BigArr(x).Elt(0) & " | " & BigArr(x).Elt(1)
    Next x

    For x = y To max_row
        '' We have to change the size of each Elt,
        '' because there are some new for,
        '' which the size has not been set, yet.
        ReDim Preserve BigArr(x).Elt(0 To 1)
        '' Take some test values
        BigArr(x).Elt(0) = Cells(x + 1, 1).Value
        BigArr(x).Elt(1) = Cells(x + 1, 2).Value
    Next x

    '' Check what we have read
    Debug.Print "BigArr size = " & UBound(BigArr) + 1
    For x = 0 To UBound(BigArr)
        Debug.Print BigArr(x).Elt(0) & " | " & BigArr(x).Elt(1)
    Next x

This might be more desirable, that is use float instead

SELECT fullName, CAST(totalBal as float) totalBal FROM client_info ORDER BY totalBal DESC

While it may immediately seem useful to utilize class instance variables, since class instance variable are shared among subclasses and they can be referred to within both singleton and instance methods, there is a singificant drawback. They are shared and so subclasses can change the value of the class instance variable, and the base class will also be affected by the change, which is usually undesirable behavior:

class C
  @@c = 'c'
  def self.c_val
    @@c
  end
end

C.c_val
 => "c" 

class D < C
end

D.instance_eval do 
  def change_c_val
    @@c = 'd'
  end
end
 => :change_c_val 

D.change_c_val
(irb):12: warning: class variable access from toplevel
 => "d" 

C.c_val
 => "d" 

Rails introduces a handy method called class_attribute. As the name implies, it declares a class-level attribute whose value is inheritable by subclasses. The class_attribute value can be accessed in both singleton and instance methods, as is the case with the class instance variable. However, the huge benefit with class_attribute in Rails is subclasses can change their own value and it will not impact parent class.

class C
  class_attribute :c
  self.c = 'c'
end

 C.c
 => "c" 

class D < C
end

D.c = 'd'
 => "d" 

 C.c
 => "c" 

Later versions of Safari allow you to Disable Cross-Origin Restrictions. Just enable the developer menu from Preferences >> Advanced, and select "Disable Cross-Origin Restrictions" from the develop menu.

If you want local only, then you only need to enable the developer menu, and select "Disable local file restrictions" from the develop menu.

document.getElementById('mybox').style.display = "block";

Best way to handle such error-"Use Annotation". spring.xml-<context:component-scan base-package=com.SpringCollection.SpringCollection"/>

add annotation in that class for which you want to use Bean ID(i am using class "First")-

@Component

public class First {

Changes In Main Class**-

ApplicationContext context = new AnnotationConfigApplicationContext(First.class); use this.

You can also use react router dom library useHistory;

`
import { useHistory } from "react-router-dom";

function HomeButton() {
  let history = useHistory();

  function handleClick() {
    history.push("/home");
  }

  return (
    <button type="button" onClick={handleClick}>
      Go home
    </button>
  );
}
`

https://reactrouter.com/web/api/Hooks/usehistory

Open you rails console

ActiveRecord::Base.connection.execute("drop table table_name")

use typeid(class).name

// illustratory code assuming all includes/namespaces etc

#include <iostream>
#include <typeinfo>
using namespace std;

struct A{};
int main(){
   cout << typeid(A).name();
}

It is important to remember that this gives an implementation defined names.

As far as I know, there is no way to get the name of the object at run time reliably e.g. 'A' in your code.

EDIT 2:

#include <typeinfo>
#include <iostream>
#include <map>
using namespace std; 

struct A{
};
struct B{
};

map<const type_info*, string> m;

int main(){
    m[&typeid(A)] = "A";         // Registration here
    m[&typeid(B)] = "B";         // Registration here

    A a;
    cout << m[&typeid(a)];
}

Use a git endpoint instead of a package name:

bower install https://github.com/jquery/jquery.git#2.0.3

I got the same error. In the terminal when I typed "python filename.py", with this command, python2 was tring to run python3 code, because the is written python3. It runs correctly when I type "python3 filename.py" in the terminal. I hope this works for you too.

For Google chrome Version 56.0.2924.87 (Latest Release) cookies are found inside profile1 folder.

If you browse that you can find variety of information.

There is a separate file called "Cookies". Also the Cache folder is inside this folder.

Path : C:\Users\user_name\AppData\Local\Google\Chrome\User Data\Profile 1

Remember to replace user_name.

For Version 61.0.3163.100
Path : C:\Users\user_name\AppData\Local\Google\Chrome\User Data\Default

Inside this folder there is Cookies file and Cache folder.

For me, the simplest way to do this is

1) Download and unzip bootstrap into vendor

2) Add the bootstrap path to your config

config.assets.paths << Rails.root.join("vendor/bootstrap-3.3.6-dist")

3) Require them

in css *= require css/bootstrap

in js //= require js/bootstrap

Done!

This methods makes the fonts load without any other special configuration and doesn't require moving the bootstrap files out of their self-contained directory.

In Angular UI Bootstrap 0.13.X, tooltip-html-unsafe has been deprecated. You should now use tooltip-html and $sce.trustAsHtml() to accomplish a tooltip with html.

https://github.com/angular-ui/bootstrap/commit/e31fcf0fcb06580064d1e6375dbedb69f1c95f25

<a href="#" tooltip-html="htmlTooltip">Check me out!</a>

$scope.htmlTooltip = $sce.trustAsHtml('I\'ve been made <b>bold</b>!');

HTML:

<div class="Settings" id="GTSettings">
  <h3 class="SettingsTitle"><a class="toggle" ><img src="${appThemePath}/images/toggle-collapse-light.gif" alt="" /></a>General Theme Settings</h3>
  <div class="options">
    <table>
      <tr>

        </td>
      </tr>
    </table>

JavaScript:

$(document).ready(function() {

  $(".options").hide();
  $(".SettingsTitle").click(function(e) {
    var appThemePath = $("#appThemePath").text();

    var closeMenuImg = appThemePath + '/images/toggle-collapse-light.gif';
    var openMenuImg = appThemePath + '/images/toggle-collapse-dark.gif';

    var elem = $(this).next('.options');
    $('.options').not(elem).hide('fast');
    $('.SettingsTitle').not($(this)).parent().children("h3").children("a.toggle").children("img").attr('src', closeMenuImg);
    elem.toggle('fast');
    var targetImg = $(this).parent().children("h3").children("a.toggle").children("img").attr('src') === closeMenuImg ? openMenuImg : closeMenuImg;
    $(this).parent().children("h3").children("a.toggle").children("img").attr('src', targetImg);
  });

});

The CSS box model is rather complicated, particularly when it comes to scrolling content. While the browser uses the values from your CSS to draw boxes, determining all the dimensions using JS is not straight-forward if you only have the CSS.

That's why each element has six DOM properties for your convenience: offsetWidth, offsetHeight, clientWidth, clientHeight, scrollWidth and scrollHeight. These are read-only attributes representing the current visual layout, and all of them are integers (thus possibly subject to rounding errors).

Let's go through them in detail:

• offsetWidth, offsetHeight: The size of the visual box incuding all borders. Can be calculated by adding width/height and paddings and borders, if the element has display: block
• clientWidth, clientHeight: The visual portion of the box content, not including borders or scroll bars , but includes padding . Can not be calculated directly from CSS, depends on the system's scroll bar size.
• scrollWidth, scrollHeight: The size of all of the box's content, including the parts that are currently hidden outside the scrolling area. Can not be calculated directly from CSS, depends on the content.

Try it out: jsFiddle

Since offsetWidth takes the scroll bar width into account, we can use it to calculate the scroll bar width via the formula

scrollbarWidth = offsetWidth - clientWidth - getComputedStyle().borderLeftWidth - getComputedStyle().borderRightWidth

Unfortunately, we may get rounding errors, since offsetWidth and clientWidth are always integers, while the actual sizes may be fractional with zoom levels other than 1.

Note that this

scrollbarWidth = getComputedStyle().width + getComputedStyle().paddingLeft + getComputedStyle().paddingRight - clientWidth

does not work reliably in Chrome, since Chrome returns width with scrollbar already substracted. (Also, Chrome renders paddingBottom to the bottom of the scroll content, while other browsers don't)

Here's a piece of code that checks whether a number is an integer or not, it works for both Python 2 and Python 3.

import sys

if sys.version < '3':
    integer_types = (int, long,)
else:
    integer_types = (int,)

isinstance(yourNumber, integer_types)  # returns True if it's an integer
isinstance(yourNumber, float)  # returns True if it's a float

Notice that Python 2 has both types int and long, while Python 3 has only type int. Source.

If you want to check whether your number is a float that represents an int, do this

(isinstance(yourNumber, float) and (yourNumber).is_integer())  # True for 3.0

If you don't need to distinguish between int and float, and are ok with either, then ninjagecko's answer is the way to go

import numbers

isinstance(yourNumber, numbers.Real)

As I wrote in the edits of the op, to edit existing excel documents you must use the xlutils module (Thanks Oliver)

Here is the proper way to do it:

#xlrd, xlutils and xlwt modules need to be installed.  
#Can be done via pip install <module>
from xlrd import open_workbook
from xlutils.copy import copy

rb = open_workbook("names.xls")
wb = copy(rb)

s = wb.get_sheet(0)
s.write(0,0,'A1')
wb.save('names.xls')

This replaces the contents of the cell located at a1 in the first sheet of "names.xls" with the text "a1", and then saves the document.

This is how I've added a bot to my channel and set up notifications:

1. Make sure the channel is public (you can set it private later)
2. Add administrators > Type the bot username and make it administrator
3. Your bot will join your channel
4. set a channel id by setting the channel url like

telegram.me/whateverIWantAndAvailable

the channel id will be @whateverIWantAndAvailable

Now set up your bot to send notifications by pusshing the messages here:

https://api.telegram.org/botTOKENOFTHEBOT/sendMessage?chat_id=@whateverIWantAndAvailable&text=Test

the message which bot will notify is: Test

I strongly suggest an urlencode of the message like

https://api.telegram.org/botTOKENOFTHEBOT/sendMessage?chat_id=@whateverIWantAndAvailable&text=Testing%20if%20this%20works

in php you can use urlencode("Test if this works"); in js you can encodeURIComponent("Test if this works");

I hope it helps

This is way I did it:

%matplotlib inline
import matplotlib.pyplot as plt
plt.rcParams["figure.figsize"] = (12, 9) # (w, h)

You can define your own sizes.

404 Not Found technically means that uri does not currently map to a resource. In your example, I interpret a request to http://mywebsite/api/user/13 that returns a 404 to imply that this url was never mapped to a resource. To the client, that should be the end of conversation.

To address concerns with ambiguity, you can enhance your API by providing other response codes. For example, suppose you want to allow clients to issue GET requests the url http://mywebsite/api/user/13, you want to communicate that clients should use the canonical url http://mywebsite/restapi/user/13. In that case, you may want to consider issuing a permanent redirect by returning a 301 Moved Permanently and supply the canonical url in the Location header of the response. This tells the client that for future requests they should use the canonical url.

I had the same problem and after hours of looking found the answer.

The error I was getting was a little different: <path> already exists and is not a valid git repo (and added here for SEO value)

The solution is to NOT create the directory that will house the submodule. The directory will be created as part of the git submodule add command.

Also, the argument is expected to be relative to the parent-repo root, not your working directory, so watch out for that.

Solution for the example above:

1. It IS okay to have your parent repo already cloned.
2. Make sure the common_code directory does not exist.
3. cd Repo
4. git submodule add git://url_to_repo projectfolder/common_code/ (Note the required trailing slash.)
5. Sanity restored.

I hope this helps someone, as there is very little information to be found elsewhere about this.

simply in your css use '.ui-datepicker{ z-index: 9999 !important;}' Here 9999 can be replaced to whatever layer value you want your datepicker available. Neither any code is to be commented nor adding 'position:relative;' css on input elements. Because increasing the z-index of input elements will have effect on all input type buttons, which may not be needed for some cases.

If using Python 2.5, you may need to import simplejson:

Detecting iOS

With iOS 13 iPad both User agent and platform strings are changed and differentiating between iPad and MacOS seems possible, so all answers below needs to take that into account now.

This might be the shortest alternative that also covers iOS 13:

function iOS() {
  return [
    'iPad Simulator',
    'iPhone Simulator',
    'iPod Simulator',
    'iPad',
    'iPhone',
    'iPod'
  ].includes(navigator.platform)
  // iPad on iOS 13 detection
  || (navigator.userAgent.includes("Mac") && "ontouchend" in document)
}

iOS will be either true or false

Worse option: User agent sniffing

User Agent sniffing is more dangerous and problems appear often.

On iPad iOS 13, the user agent is identical with that of a MacOS 13 computer, but if you ignore iPads this might work still for a while:

var iOS = !window.MSStream && /iPad|iPhone|iPod/.test(navigator.userAgent); // fails on iPad iOS 13

The !window.MSStream is to not incorrectly detect IE11, see here and here.

Note: Both navigator.userAgent and navigator.platform can be faked by the user or a browser extension.

Browser extensions to change userAgent or platform exist because websites use too heavy-handed detection and often disable some features even if the user's browser would otherwise be able to use that feature.

To de-escalate this conflict with users it's recommended to detect specifically for each case the exact features that your website needs. Then when the user gets a browser with the needed feature it will already work without additional code changes.

Detecting iOS version

The most common way of detecting the iOS version is by parsing it from the User Agent string. But there is also feature detection inference*;

We know for a fact that history API was introduced in iOS4 - matchMedia API in iOS5 - webAudio API in iOS6 - WebSpeech API in iOS7 and so on.

Note: The following code is not reliable and will break if any of these HTML5 features is deprecated in a newer iOS version. You have been warned!

function iOSversion() {

  if (iOS) { // <-- Use the one here above
    if (window.indexedDB) { return 'iOS 8 and up'; }
    if (window.SpeechSynthesisUtterance) { return 'iOS 7'; }
    if (window.webkitAudioContext) { return 'iOS 6'; }
    if (window.matchMedia) { return 'iOS 5'; }
    if (window.history && 'pushState' in window.history) { return 'iOS 4'; }
    return 'iOS 3 or earlier';
  }

  return 'Not an iOS device';
}

Here is the answer straight from baeldung's reference page :- https://www.baeldung.com/spring-optional-path-variables

You need to use a third party plugin like AndroidIcons Drawable Import to install this. Goto Android Studio > Prefrences > Plugins > and browse for AndroidIcons Drawable You can do things like

1. AndroidIcons Drawable Import
2. Material Icons Drawable Import
3. Scaled Drawable
4. Multisource-Drawable

Restart android studio. If you do not have the drawables folder created, create it by importing any image as -"Action Bar and Tab Icons" & "Notification Icons",. Then right clink on the file explorer and you can see 4 options in the new tab. Use any one according to your need.

With Vim 8.0 or later you can run a terminal emulator in a vim window by using the terminal feature. BTW if you want to simulate modern IDE terminal (like VSCode integrated terminal) in gVim or MacVim, you can put the following configuration in you vimrc.

set shell=/path/to/shell

" Make sure to replace `sh.exe` in BufNr("sh.exe") with your shell executable.
nnoremap <expr> <space> BufNr("sh.exe") > 0 ? (&buftype == 'terminal' ? '<c-^>' : ':b '. BufNr("sh.exe") . '<cr>') : ':terminal ++curwin<cr>'

function! BufNr(pattern)
  let bufcount = bufnr("$")
  let currbufnr = 1
  let nummatches = 0
  let firstmatchingbufnr = 0
  while currbufnr <= bufcount
    if(bufexists(currbufnr))
      let currbufname = bufname(currbufnr)
      if(match(currbufname, a:pattern) > -1)
        let nummatches += 1
        let firstmatchingbufnr = currbufnr
      endif
    endif
    let currbufnr = currbufnr + 1
  endwhile
  return firstmatchingbufnr
endf

Now you can use space in normal mode (or whatever mapping you chosen) to:

1. Open a terminal in current window if terminal doesn't exists yet.
2. Switch to terminal buffer if current buffer is not a terminal type.
3. Switch to previous buffer if current buffer is a terminal buffer.

NanoHttpd works like a charm on Android -- we have code in production, in users hands, that's built on it.

The license absolutely allows commercial use of NanoHttpd, without any "viral" implications.

The error you receive is from another method than the one you show here. It's a method that takes a parameter with the name "source". In your Visual Studio Options dialog, disable "Just my code", disable "Step over properties and operators" and enable "Enable .NET Framework source stepping". Make sure the .NET symbols can be found. Then the debugger will break inside the .NET method if it isn't your own. then check the stacktrace to find which value is passed that's null, but shouldn't.

What you should look for is a value that becomes null and prevent that. From looking at your code, it may be the itemsal.Add line that breaks.

Edit

Since you seem to have trouble with debugging in general and LINQ especially, let's try to help you out step by step (also note the expanded first section above if you still want to try it the classic way, I wasn't complete the first time around):

• Narrow down the possible error scenarios by splitting your code;
• Replace locations that can end up null with something deliberately not null;
• If all fails, rewrite your LINQ statement as loop and go through it step by step.

Step 1

First make the code a bit more readable by splitting it in manageable pieces:

// in your using-section, add this:
using Roundsman.BAL;

// keep this in your normal location
var nCounts = from sale in sal
              select new
              {
                  SaleID = sale.OrderID,
                  LineItem = GetLineItem(sale.LineItems)
              };

foreach (var item in nCounts)
{
    foreach (var itmss in item.LineItem)
    {
        itemsal.Add(CreateWeeklyStockList(itmss));
    }
}


// add this as method somewhere
WeeklyStockList CreateWeeklyStockList(LineItem lineItem)
{
    string name = itmss.Item.Name.ToString();  // isn't Name already a string?
    string code = itmss.Item.Code.ToString();  // isn't Code already a string?
    string description = itmss.Item.Description.ToString();  // isn't Description already a string?
    int quantity = Convert.ToInt32(itmss.Item.Quantity); // wouldn't (int) or "as int" be enough?

    return new WeeklyStockList(
                 name, 
                 code, 
                 description,
                 quantity, 
                 2, 2, 2, 2, 2, 2, 2, 2, 2
              );
}

// also add this as a method
LineItem GetLineItem(IEnumerable<LineItem> lineItems)
{
    // add a null-check
    if(lineItems == null)
        throw new ArgumentNullException("lineItems", "Argument cannot be null!");

    // your original code
    from sli in lineItems
    group sli by sli.Item into ItemGroup
    select new
    {
        Item = ItemGroup.Key,
        Weeks = ItemGroup.Select(s => s.Week)
    }
}

The code above is from the top of my head, of course, because I cannot know what type of classes you have and thus cannot test the code before posting. Nevertheless, if you edit it until it is correct (if it isn't so out of the box), then you already stand a large chance the actual error becomes a lot clearer. If not, you should at the very least see a different stacktrace this time (which we still eagerly await!).

Step 2

The next step is to meticulously replace each part that can result in a null reference exception. By that I mean that you replace this:

select new
{
    SaleID = sale.OrderID,
    LineItem = GetLineItem(sale.LineItems)
};

with something like this:

select new
{
    SaleID = 123,
    LineItem = GetLineItem(new LineItem(/*ctor params for empty lineitem here*/))
};

This will create rubbish output, but will narrow the problem down even further to your potential offending line. Do the same as above for other places in the LINQ statements that can end up null (just about everything).

Step 3

This step you'll have to do yourself. But if LINQ fails and gives you such headaches and such unreadable or hard-to-debug code, consider what would happen with the next problem you encounter? And what if it fails on a live environment and you have to solve it under time pressure=

The moral: it's always good to learn new techniques, but sometimes it's even better to grab back to something that's clear and understandable. Nothing against LINQ, I love it, but in this particular case, let it rest, fix it with a simple loop and revisit it in half a year or so.

Conclusion

Actually, nothing to conclude. I went a bit further then I'd normally go with the long-extended answer. I just hope it helps you tackling the problem better and gives you some tools understand how you can narrow down hard-to-debug situations, even without advanced debugging techniques (which we haven't discussed).

I had a similar problem with é char... I think the comment "it's possible that the text you're feeding it isn't UTF-8" is probably close to the mark here. I have a feeling the default collation in my instance was something else until I realized and changed to utf8... problem is the data was already there, so not sure if it converted the data or not when i changed it, displays fine in mysql workbench. End result is that php will not json encode the data, just returns false. Doesn't matter what browser you use as its the server causing my issue, php will not parse the data to utf8 if this char is present. Like i say not sure if it is due to converting the schema to utf8 after data was present or just a php bug. In this case use json_encode(utf8_encode($string));

  include_directories("${gtest_SOURCE_DIR}/include"
                      "${gmock_SOURCE_DIR}/include")
endif()

# Now simply link your own targets against gtest, gmock,
# etc. as appropriate

However it does seem quite hacky. I'd like to propose an alternative solution - use Git submodules.

cd MyProject/dependencies/gtest
git submodule add https://github.com/google/googletest.git
cd googletest
git checkout release-1.8.0
cd ../../..
git add *
git commit -m "Add googletest"

Then in MyProject/dependencies/gtest/CMakeList.txt you can do something like:

cmake_minimum_required(VERSION 3.3)

if(TARGET gtest) # To avoid diamond dependencies; may not be necessary depending on you project.
    return()
endif()

add_subdirectory("googletest")

I haven't tried this extensively yet but it seems cleaner.

Edit: There is a downside to this approach: The subdirectory might run install() commands that you don't want. This post has an approach to disable them but it was buggy and didn't work for me.

Edit 2: If you use add_subdirectory("googletest" EXCLUDE_FROM_ALL) it seems means the install() commands in the subdirectory aren't used by default.

The object of the exercise is to find the row that contains the information. When we get there, we can easily extract the required information.

Answer

$(".use-address").click(function() {
    var $item = $(this).closest("tr")   // Finds the closest row <tr> 
                       .find(".nr")     // Gets a descendent with class="nr"
                       .text();         // Retrieves the text within <td>

    $("#resultas").append($item);       // Outputs the answer
});

VIEW DEMO

Now let's focus on some frequently asked questions in such situations.

How to find the closest row?

Using .closest():

var $row = $(this).closest("tr");

Using .parent():

You can also move up the DOM tree using .parent() method. This is just an alternative that is sometimes used together with .prev() and .next().

var $row = $(this).parent()             // Moves up from <button> to <td>
                  .parent();            // Moves up from <td> to <tr>

Getting all table cell <td> values

So we have our $row and we would like to output table cell text:

var $row = $(this).closest("tr"),       // Finds the closest row <tr> 
    $tds = $row.find("td");             // Finds all children <td> elements

$.each($tds, function() {               // Visits every single <td> element
    console.log($(this).text());        // Prints out the text within the <td>
});

VIEW DEMO

Getting a specific <td> value

Similar to the previous one, however we can specify the index of the child <td> element.

var $row = $(this).closest("tr"),        // Finds the closest row <tr> 
    $tds = $row.find("td:nth-child(2)"); // Finds the 2nd <td> element

$.each($tds, function() {                // Visits every single <td> element
    console.log($(this).text());         // Prints out the text within the <td>
});

VIEW DEMO

Useful methods

• .closest() - get the first element that matches the selector
• .parent() - get the parent of each element in the current set of matched elements
• .parents() - get the ancestors of each element in the current set of matched elements
• .children() - get the children of each element in the set of matched elements
• .siblings() - get the siblings of each element in the set of matched elements
• .find() - get the descendants of each element in the current set of matched elements
• .next() - get the immediately following sibling of each element in the set of matched elements
• .prev() - get the immediately preceding sibling of each element in the set of matched elements

To use the environment virtualenv has created, you first need to source env/bin/activate. After that, just install packages using pip install package-name.

You don't need to do special things in the form. You just build the comment correctly in the show action:

class ArticlesController < ActionController::Base
  ....
  def show
    @article = Article.find(params[:id])
    @new_comment = @article.comments.build
  end
  ....
end

and then make a form for it in the article view:

<% form_for @new_comment do |f| %>
   <%= f.text_area :text %>
   <%= f.submit "Post Comment" %>
<% end %>

by default, this comment will go to the create action of CommentsController, which you will then probably want to put redirect :back into so you're routed back to the Article page.

I am using a UISplitViewController with a navigationcontroller and a tableviewcontroller. This worked for me in the master view after trying many solutions here:

float systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];
if (systemVersion >= 7.0f) {

    // Move the view down 20 pixels
    CGRect bounds = self.view.bounds;
    bounds.origin.y -= 20.0;
    [self.navigationController.view setBounds:bounds];

    // Create a solid color background for the status bar
    CGRect statusFrame = CGRectMake(0.0, -20.0, bounds.size.width, 20);
    UIView* statusBar = [[UIView alloc] initWithFrame:statusFrame];
    statusBar.backgroundColor = [UIColor whiteColor];
    [statusBar setAlpha:1.0f];
    [statusBar setOpaque:YES];
    [self.navigationController.view addSubview:statusBar];
}

It's similar to Hot Licks' solution but applies the subview to the navigationController.

I know this is an old thread, but thought I may add on a little extra. In my case I was wanting to pass on the text, val and some other data attr. In this case its better to store the whole option as a prev value rather than just the val.

Example code below:

var $sel = $('your select');
$sel.data("prevSel", $sel.clone());
$sel.on('change', function () {
    //grab previous select
    var prevSel = $(this).data("prevSel");

    //do what you want with the previous select
    var prevVal = prevSel.val();
    var prevText = prevSel.text();
    alert("option value - " + prevVal + " option text - " + prevText)

    //reset prev val        
    $(this).data("prevSel", $(this).clone());
});

EDIT:

I forgot to add .clone() onto the element. in not doing so when you try to pull back the values you end up pulling in the new copy of the select rather than the previous. Using the clone() method stores a copy of the select instead of an instance of it.

You can use this

function removeEntity(object) {
    var scene = document.querySelectorAll("scene");                               //clear the objects from the scene
    for (var i = 0; i < scene.length; i++) {                                    //loop through to get all object in the scene
    var scene =document.getElementById("scene");                                  
    scene.removeChild(scene.childNodes[0]);                                        //remove all specified objects
  }   

I see that this is answered already, but I believe I have a simple jQuery solution ( jQuery is not even really needed; I just enjoy using it ):

I suggest counting the line breaks in the textarea text and setting the rows attribute of the textarea accordingly.

var text = jQuery('#your_textarea').val(),
    // look for any "\n" occurences
    matches = text.match(/\n/g),
    breaks = matches ? matches.length : 2;

jQuery('#your_textarea').attr('rows',breaks + 2);

This works for me in Ubuntu 17.10 (Artful Aardvark):

apt-get update
apt-get install build-essential

If you got multiple lines by delimited by \n (normally new line). You can use 'cut' as well:

echo "$data" | cut -f2 -d$'\n'

You will get the 2nd line from the file. -f3 gives you the 3rd line.

Try + (instancetype)appearance of UITableView:

Objective-C:

[[UITableView appearance] setSeparatorColor:[UIColor blackColor]]; // set your desired colour in place of "[UIColor blackColor]"

Swift 3.0:

UITableView.appearance().separatorColor = UIColor.black // set your desired colour in place of "UIColor.black"

Note: Change will reflect to all tables used in application.

If all else fails, open the file in binary to make sure there are no funny characters [3 non printable characters at the beginning of the file that identify the file as utf-8] at the beginning of the file. We did this and found some. so we converted the file from utf-8 to ascii and it worked.

HTMLUNIT is the package if you're a java developer. http://htmlunit.sourceforge.net/apidocs/index.html

You are iterating over one string (word), but then using the index into that to look up a character in so_far. There is no guarantee that these two strings have the same length.

Firstly, in histories_T, you are referencing table T_customer (should be T_customers) and secondly, you are missing the FOREIGN KEY clause that REFERENCES orders; which is not being created (or dropped) with the code you provided.

There may be additional errors as well, and I admit Oracle has never been very good at describing the cause of errors - "Mutating Tables" is a case in point.

Let me know if there additional problems you are missing.

Here is a solution to your problem:

I've tried to solve problem like yours & I want to suggest to test from simple aspect.

Follow these steps: Learn from simple solution.

Step 1: Create a table schema using this SQL Query:

CREATE TABLE IF NOT EXISTS `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(30) NOT NULL,
  `password` varchar(32) NOT NULL,
  `status` tinyint(1) DEFAULT '0',
  PRIMARY KEY (`id`),
  UNIQUE KEY `no_duplicate` (`username`,`password`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1;

Step 2: Create an index of two columns to prevent duplicate data using following SQL Query:

ALTER TABLE `user` ADD INDEX no_duplicate (`username`, `password`);

or, Create an index of two column from GUI as follows:

Step 3: Update if exist, insert if not using following queries:

INSERT INTO `user`(`username`, `password`) VALUES ('ersks','Nepal') ON DUPLICATE KEY UPDATE `username`='master',`password`='Nepal';

INSERT INTO `user`(`username`, `password`) VALUES ('master','Nepal') ON DUPLICATE KEY UPDATE `username`='ersks',`password`='Nepal';

If you only want to install the latest official JRE from Oracle, you can get it there, install it, and export the new JAVA_HOME in the terminal.

• Open your Terminal
• java -version gives you an error and a popup
• Get the JRE dmg on http://www.oracle.com/technetwork/java/javase/downloads/index.html
• Install it
• In your terminal, type: export JAVA_HOME="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home"
• java -version now gives you java version "1.7.0_45"

That's the cleanest way I found to install the latest JRE.

You can add the export JAVA_HOME line in your .bashrc to have java permanently in your Terminal:

echo export JAVA_HOME=\"/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home\" >> ~/.bashrc

In Python, the tendency is usually that one would use a non-fixed size list (that is to say items can be appended/removed to it dynamically). If you followed this, there would be no need to allocate a fixed-size collection ahead of time and fill it in with empty values. Rather, as you get or create strings, you simply add them to the list. When it comes time to remove values, you simply remove the appropriate value from the string. I would imagine you can probably use this technique for this. For example (in Python 2.x syntax):

>>> temp_list = []
>>> print temp_list
[]
>>> 
>>> temp_list.append("one")
>>> temp_list.append("two")
>>> print temp_list
['one', 'two']
>>> 
>>> temp_list.append("three")
>>> print temp_list
['one', 'two', 'three']
>>> 

Of course, some situations might call for something more specific. In your case, a good idea may be to use a deque. Check out the post here: Python, forcing a list to a fixed size. With this, you can create a deque which has a fixed size. If a new value is appended to the end, the first element (head of the deque) is removed and the new item is appended onto the deque. This may work for what you need, but I don't believe this is considered the "norm" for Python.

import math
from itertools import izip

def dot_product(v1, v2):
    return sum(map(lambda x: x[0] * x[1], izip(v1, v2)))

def cosine_measure(v1, v2):
    prod = dot_product(v1, v2)
    len1 = math.sqrt(dot_product(v1, v1))
    len2 = math.sqrt(dot_product(v2, v2))
    return prod / (len1 * len2)

You can round it after computing:

cosine = format(round(cosine_measure(v1, v2), 3))

If you want it really short, you can use this one-liner:

from math import sqrt
from itertools import izip

def cosine_measure(v1, v2):
    return (lambda (x, y, z): x / sqrt(y * z))(reduce(lambda x, y: (x[0] + y[0] * y[1], x[1] + y[0]**2, x[2] + y[1]**2), izip(v1, v2), (0, 0, 0)))

Thanks for all the answers but none of them worked for me. Although some of them gave me some ideas on what services and stuff that needs to be running to be able "turn on" the debugging of my web app again:

1. Ensure that ASP.Net registered properly with IIS and running. To register it follow @Rahul Tripathi instructions then go to Search > type services.msc and make sure that ASP.Net State Service is running.
2. As @Morvael suggested, always run your VS in admin mode.
3. Check if the app pool where your web app resides is started.
4. Ensure that the IIS server itself is running (this what solved the problem for me)

I still haven't figured out what is the reason why my IIS stopped. It was working fine yesterday then today it's not. Anyways, I hope this mini checklist helps somebody else. Cheers!

You can also use MethodBase.GetCurrentMethod() which will inhibit the JIT compiler from inlining the method where it's used.

Update:

This method contains a special enumeration StackCrawlMark that from my understanding will specify to the JIT compiler that the current method should not be inlined.

This is my interpretation of the comment associated to that enumeration present in SSCLI. The comment follows:

// declaring a local var of this enum type and passing it by ref into a function 
// that needs to do a stack crawl will both prevent inlining of the calle and 
// pass an ESP point to stack crawl to
// 
// Declaring these in EH clauses is illegal; 
// they must declared in the main method body

i wrote a small function.. but works for me

def conv(strng):
    k=strng
    k=k.replace('\a','\\a')
    k=k.replace('\b','\\b')
    k=k.replace('\f','\\f')
    k=k.replace('\n','\\n')
    k=k.replace('\r','\\r')
    k=k.replace('\t','\\t')
    k=k.replace('\v','\\v')
    return k

Since TypeScript 3.7 was released you can use optional chaining now.

Property example:

let x = foo?.bar.baz();

This is equvalent to:

let x = (foo === null || foo === undefined) ?
    undefined :
    foo.bar.baz();

Moreover you can call:

Optional Call

function(otherFn: (par: string) => void) {
   otherFn?.("some value");
}

otherFn will be called only if otherFn won't be equal to null or undefined

Usage optional chaining in IF statement

This:

if (someObj && someObj.someProperty) {
    // ...
}

can be replaced now with this

if (someObj?.someProperty) {
    // ...
}

use like this :-

gridview1.DataSource = ds.Tables[0]; <-- Use index or your table name which you want to bind
gridview1.DataBind();

I hope it helps!!

The reason it prints "three" is because you didnt define your array. The equivalent to what you're doing is:

arr = []
for i in array :
    if i == "two" :
        arr.push(i)
print(i)

You are asking for the last element it looked through, which is not what you should be doing. You need to be storing the array to a variable in order to get the element.

The english equivalent of what you are doing is:

You: "I need you to print all the elements in this array that equal two, but in an array. And each time you cycle through the list, define the current element as I."
Computer: "Here: ["two"]"
You: "Now tell me 'i'"
Computer: "'i' is equal to "three"
You: "Why?"

The reason 'i' is equal to "three" is because three was the last thing that was defined as I

the computer did:

i = "one"
i = "two"
i = "three"

print(["two"])

Because you asked it to.

If you want the index, go here If you want the values in an array, define the array, like this:

MyArray = [(i) for i in my_list if i=="two"]

You can use the DOMSubtreeModified event

$(something).bind('DOMSubtreeModified' ...

But this will fire even if the dimensions don't change, and reassigning the position whenever it fires can take a performance hit. In my experience using this method, checking whether the dimensions have changed is less expensive and so you might consider combining the two.

Or if you are directly altering the div (rather than the div being altered by user input in unpredictable ways, like if it is contentEditable), you can simply fire a custom event whenever you do so.

Downside: IE and Opera don't implement this event.

Simply:

x <- vector(mode="numeric", length=0)

Check you gradle settings, it may be set to Offline Work

You might need to do some checking. You cannot safely convert factors directly to numeric. as.character must be applied first. Otherwise, the factors will be converted to their numeric storage values. I would check each column with is.factor then coerce to numeric as necessary.

df1[] <- lapply(df1, function(x) {
    if(is.factor(x)) as.numeric(as.character(x)) else x
})
sapply(df1, class)
#         a         b 
# "numeric" "numeric" 

I would recommend the rename command for this. Type ren /? at the command line for more help.

You are returning a reference to ret which is a variable on the stack.

Normally you should use margin: 0 auto on the div as mentioned in the other answers, but you'll have to specify a width for the div. If you don't want to specify a width you could either (this is depending on what you're trying to do) use margins, something like margin: 0 200px; , this should make your content seems as if it's centered, you could also see the answer of Leyu to my question

Pure javascript can do!

var scrollTop = window.pageYOffset || document.documentElement.scrollTop;

You could use Linq's Aggregate function:

string s = "the\nquick\tbrown\rdog,jumped;over the lazy fox.";
char[] chars = new char[] { ' ', ';', ',', '\r', '\t', '\n' };
string snew = chars.Aggregate(s, (c1, c2) => c1.Replace(c2, '\n'));

Here's the extension method:

public static string ReplaceAll(this string seed, char[] chars, char replacementCharacter)
{
    return chars.Aggregate(seed, (str, cItem) => str.Replace(cItem, replacementCharacter));
}

Extension method usage example:

string snew = s.ReplaceAll(chars, '\n');

You can easily do this using _.pick:

var model = {
  fname: null,
  lname: null
};

var credentials = {
  fname: 'abc',
  lname: 'xyz',
  age: 2
};

var result = _.pick(credentials, _.keys(model));


console.log('result =', result);

But you can simply use pure JavaScript (specially if you use ECMAScript 6), like this:

const model = {
  fname: null,
  lname: null
};

const credentials = {
  fname: 'abc',
  lname: 'xyz',
  age: 2
};

const newModel = {};

Object.keys(model).forEach(key => newModel[key] = credentials[key]);

console.log('newModel =', newModel);

Inheritance is a concept related to code reuse. For example if I have a parent class say Animal and it contains certain attributes and methods (for this example say makeNoise() and sleep()) and I create two child classes called Dog and Cat. Since both dogs and cats go to sleep in the same fashion( I would assume) there is no need to add more functionality to the sleep() method in the Dog and Cat subclasses provided by the parent class Animal. However, a Dog barks and a Cat meows so although the Animal class might have a method for making a noise, a dog and a cat make different noises relative to each other and other animals. Thus, there is a need to redefine that behavior for their specific types. Thus the definition of polymorphism. Hope this helps.

Note that PIL will not apply the EXIF rotation information (at least up to v7.1.1; used in many jpgs). A quick fix to accomodate this:

def get_image_dims(file_path):
    from PIL import Image as pilim
    im = pilim.open(file_path)
    # returns (w,h) after rotation-correction
    return im.size if im._getexif().get(274,0) < 5 else im.size[::-1]

The jQuery UI sortable feature includes a serialize method to do this. It's quite simple, really. Here's a quick example that sends the data to the specified URL as soon as an element has changes position.

$('#element').sortable({
    axis: 'y',
    update: function (event, ui) {
        var data = $(this).sortable('serialize');

        // POST to server using $.post or $.ajax
        $.ajax({
            data: data,
            type: 'POST',
            url: '/your/url/here'
        });
    }
});

What this does is that it creates an array of the elements using the elements id. So, I usually do something like this:

<ul id="sortable">
   <li id="item-1"></li>
   <li id="item-2"></li>
   ...
</ul>

When you use the serialize option, it will create a POST query string like this: item[]=1&item[]=2 etc. So if you make use - for example - your database IDs in the id attribute, you can then simply iterate through the POSTed array and update the elements' positions accordingly.

For example, in PHP:

$i = 0;

foreach ($_POST['item'] as $value) {
    // Execute statement:
    // UPDATE [Table] SET [Position] = $i WHERE [EntityId] = $value
    $i++;
}

Example on jsFiddle.

One of reasons why you will get this Notice: Array to string conversion in… is that you are combining group of arrays. Example, sorting out several first and last names.

To echo elements of array properly, you can use the function, implode(separator, array) Example:

implode(' ', $var)

result:

first name[1], last name[1]
first name[2], last name[2]

More examples from W3C.

C based languages copy C to some degree. The tm structure (defined in time.h) has an integer field tm_mon with the (commented) range of 0-11.

C based languages start arrays at index 0. So this was convenient for outputting a string in an array of month names, with tm_mon as the index.

var path = window.location.pathname;
var page = path.split("/").pop();
console.log( page );

You will have to use two different containers, one for the background image and the other for your content.

In the example, I have created two containers, .background-image and .content.

Both of them are placed with position: fixed and left: 0; right: 0;. The difference in displaying them comes from the z-index values which have been set differently for the elements.

.background-image {
  position: fixed;
  left: 0;
  right: 0;
  z-index: 1;
  display: block;
  background-image: url('https://i.imgur.com/lL6tQfy.png');
  width: 1200px;
  height: 800px;
  -webkit-filter: blur(5px);
  -moz-filter: blur(5px);
  -o-filter: blur(5px);
  -ms-filter: blur(5px);
  filter: blur(5px);
}

.content {
  position: fixed;
  left: 0;
  right: 0;
  z-index: 9999;
  margin-left: 20px;
  margin-right: 20px;
}

<div class="background-image"></div>
<div class="content">
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis aliquam erat in ante malesuada, facilisis semper nulla semper. Phasellus sapien neque, faucibus in malesuada quis, lacinia et libero. Sed sed turpis tellus. Etiam ac aliquam tortor, eleifend

pause command is what you looking for. If you looking ONLY the case when enter is hit you can abuse the runas command:

runas /user:# "" >nul 2>&1

the screen will be frozen until enter is hit.What I like more than set/p= is that if you press other buttons than enter they will be not displayed.

public boolean isInt(String str){
    return (str.lastIndexOf("-") == 0 && !str.equals("-0")) ? str.substring(1).matches(
            "\\d+") : str.matches("\\d+");

While this is usefull in rare cases (if that was not the case, the language would've allowed it directly), take a look at the Base from Member idiom. It's not a code free solution, you'd have to add an extra layer of inheritance, but it gets the job done. To avoid boilerplate code you could use boost's implementation

This could be updated to ES6 with arrow functions and look like:

getFeed().then(data => vm.feed = data);

If you wish to use the async function, you could also do like that:

async function myFunction(){
    vm.feed = await getFeed();
    // do whatever you need with vm.feed below
 }

Well, it seems that the Content-Disposition header was originally created for e-mail, not the web. (Link to relevant RFC.)

I'm guessing that web browsers may respond to

Response.AppendHeader("content-disposition", "inline; filename=" + fileName);

when saving, but I'm not sure.

When you correct the measurements - as mentioned above: Any and Exists, and adding average - we'll get following output:

Executing search Exists() 1000 times ... 
Average Exists(): 35566,023
Fastest Exists() execution: 32226 

Executing search Any() 1000 times ... 
Average Any(): 58852,435
Fastest Any() execution: 52269 ticks

Spring is an application framework which deals with IOC (Inversion of Control).

Struts 2 is a web application MVC framework which deals with actions.

Hibernate is an ORM (Object-Relational Mapping) that deals with persistent data.

Since the release of iOS 8, UIAlertView is now deprecated; UIAlertController is the replacement.

Here is a sample of how it looks in Swift:

let alert = UIAlertController(title: "Hello!", message: "Message", preferredStyle: UIAlertControllerStyle.alert)
let alertAction = UIAlertAction(title: "OK!", style: UIAlertActionStyle.default)
{
    (UIAlertAction) -> Void in
}
alert.addAction(alertAction)
present(alert, animated: true)
{
    () -> Void in
}

As you can see, the API allows us to implement callbacks for both the action and when we are presenting the alert, which is quite handy!

Updated for Swift 4.2

let alert = UIAlertController(title: "Hello!", message: "Message", preferredStyle: .alert)
let alertAction = UIAlertAction(title: "OK!", style: .default)
        {
            (UIAlertAction) -> Void in
        }
        alert.addAction(alertAction)
        present(alert, animated: true)
        {
            () -> Void in
        }

set scrolling="no" attribute in your iframe.

And this for clearing all controls in form like textbox, checkbox, radioButton

you can add different types you want..

private void ClearTextBoxes(Control control)
    {
        foreach (Control c in control.Controls)
        {
            if (c is TextBox)
            {
                ((TextBox)c).Clear();
            }

            if (c.HasChildren)
            {
                ClearTextBoxes(c);
            }


            if (c is CheckBox)
            {

                ((CheckBox)c).Checked = false;
            }

            if (c is RadioButton)
            {
                ((RadioButton)c).Checked = false;
            }
        }
    }

If you click at the icon on the upper left corner, a drop-down menu will appear, and you can find the option to copy/paste from there.

Try this:

1. create your table on the target server using your scripts from the Script Table As / Create Script step

2. on the target server, you can then issue a T-SQL statement:

   INSERT INTO dbo.YourTableNameHere
      SELECT *
      FROM [SourceServer].[SourceDatabase].dbo.YourTableNameHere
   

This should work just fine.

mysql default port is 3306 can you try putting it and then try

ENABLEDELAYEDEXPANSION is a parameter passed to the SETLOCAL command (look at setlocal /?)

Its effect lives for the duration of the script, or an ENDLOCAL:

When the end of a batch script is reached, an implied ENDLOCAL is executed for any outstanding SETLOCAL commands issued by that batch script.

In particular, this means that if you use SETLOCAL ENABLEDELAYEDEXPANSION in a script, any environment variable changes are lost at the end of it unless you take special measures.

Tried this yet?

error_reporting(0);
@ini_set('display_errors', 0);

Just set the outline to none like this

[Identifier] { outline:none; }

Using Node.js

sync mode:

var fs = require("fs");
var text = fs.readFileSync("./mytext.txt");
var textByLine = text.split("\n")

async mode:

var fs = require("fs");
fs.readFile("./mytext.txt", function(text){
    var textByLine = text.split("\n")
});

UPDATE

As of at least Node 6, readFileSync returns a Buffer, so it must first be converted to a string in order for split to work:

var text = fs.readFileSync("./mytext.txt").toString('utf-8');

Or

var text = fs.readFileSync("./mytext.txt", "utf-8");

Do you see what the DatabaseUtils.queryNumEntries() does? It's awful! I use this.

public int getRowNumberByArgs(Object... args) {
    String where = compileWhere(args);
    String raw = String.format("SELECT count(*) FROM %s WHERE %s;", TABLE_NAME, where);
    Cursor c = getWriteableDatabase().rawQuery(raw, null);
    try {
        return (c.moveToFirst()) ? c.getInt(0) : 0;
    } finally {
        c.close();
    }
}

It can be solved by using different attribute.

• Use the cell Control click event.
• Select the column value that your transpose to anther column.
• send the selected value to the another text box or level whatever you fill convenient and a complementary button to modify the selected property.
• update the whole stack op the database and make a algorithm with sql query to overcome this one to transpose it into the another column.

Please Use map() python function.

Input: In case of list of values

index = [u'CARBO1004' u'CARBO1006' u'CARBO1008' u'CARBO1009' u'CARBO1020']

encoded_string = map(str, index)

Output: ['CARBO1004', 'CARBO1006', 'CARBO1008', 'CARBO1009', 'CARBO1020']

For a Single string input:

index = u'CARBO1004'
# Use Any one of the encoding scheme.
index.encode("utf-8")  # To utf-8 encoding scheme
index.encode('ascii', 'ignore')  # To Ignore Encoding Errors and set to default scheme

Output: 'CARBO1004'

In WinForms, ValueMember and DisplayMember are used when data-binding the list. If you're not data-binding, then you can add any arbitrary object as a ListItem.

The catch to that is that, in order to display the item, ToString() will be called on it. Thus, it is highly recommended that you only add objects to the ListBox where calling ToString() will result in meaningful output.

I think Shaz's answer for local variables is hard to understand, though it works for non-recursive functions. Here's another way that I think it's clearer (but it's still his idea, exact same behavior). It's also not accessing the local variables dynamically, just the property of the local variable.

Essentially, it's using a global variable (attached to the function object)

// Here's  a version of it that is more straight forward.
function doIt() {
    doIt.objname = {};
    var someObject = "objname";
    doIt[someObject].value = "value";    
    console.log(doIt.objname);
})();

Which is essentially the same thing as creating a global to store the variable, so you can access it as a property. Creating a global to do this is such a hack.

Here's a cleaner hack that doesn't create global variables, it uses a local variable instead.

function doIt() {
  var scope = {
     MyProp: "Hello"
  };
  var name = "MyProp";
  console.log(scope[name]);
}

See Javascript: interpret string as object reference?

Here is my recursive approach:

function visit(object) {
    if (isIterable(object)) {
        forEachIn(object, function (accessor, child) {
            visit(child);
        });
    }
    else {
        var value = object;
        console.log(value);
    }
}

function forEachIn(iterable, functionRef) {
    for (var accessor in iterable) {
        functionRef(accessor, iterable[accessor]);
    }
}

function isIterable(element) {
    return isArray(element) || isObject(element);
}

function isArray(element) {
    return element.constructor == Array;
}

function isObject(element) {
    return element.constructor == Object;
}

Just a basic example:

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
Button button1;
button1.setLayoutParams(params);

params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.RIGHT_OF, button1.getId());
Button button2;
button2.setLayoutParams(params);

As you can see, this is what you have to do:

1. Create a RelativeLayout.LayoutParams object.
2. Use addRule(int) or addRule(int, int) to set the rules. The first method is used to add rules that don't require values.
3. Set the parameters to the view (in this case, to each button).

Range("A1").value = Environ("Username")

This is better than Application.Username, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.

• Application Username is the name of the User set in Excel > Tools > Options
• Environ("Username") is the name you registered for Windows; see Control Panel >System

I got the same message ("repository element was not specified in the POM inside distributionManagement element"). I checked /target/checkout/pom.xml and as per another answer and it really lacked <distributionManagement>.

It turned out that the problem was that <distributionManagement> was missing in pom.xml in my master branch (using git).

After cleaning up (mvn release:rollback, mvn clean, mvn release:clean, git tag -d v1.0.0) I run mvn release again and it worked.

For your first question, iterate the list and use a dictionary to keep track of an elements existsence.

For your second question, just use the set operator.

First You Have To Add Name Of Your Module In setting.gradle(Project Setting) File Like This..

include ':app', ':simple-crop-image-lib'

Then You Need To Compile This Module Into build.gradle(Module app) File Like This..

implementation project(':simple-crop-image-lib')

That's all for adding module now it will be appear in android  section or project section as well.

If It's till did't appear rebuild or clean your project..

The Eclipse releases are named after the moons of Jupiter, and each denotes a successive release.

Helios is the current release you can download eclipse as your programming needs http://www.eclipse.org/downloads/

When we first moved over to Vista with Oracle 10g, we experienced this issue when we installed the Oracle client on our Vista boxes, even when we were running with admin privileges during install.

Oracle brought out a new version of the 10g client (10.2.0.3) that was Vista compatible.

I do believe that this was after 11g was released, so it is possible that there is a 'Vista compatible' version for 11g also.

Run 'npm install' it will install all necessary pkg .

You have to first obtain the Range object. Also, getCell() will not return the value of the cell but instead will return a Range object of the cell. So, use something on the lines of

function email() {

// Opens SS by its ID

var ss = SpreadsheetApp.openById("0AgJjDgtUl5KddE5rR01NSFcxYTRnUHBCQ0stTXNMenc");

// Get the name of this SS

var name = ss.getName();  // Not necessary 

// Read cell 1,1 * Line below does't work *

// var data = Range.getCell(0, 0);
var sheet = ss.getSheetByName('Sheet1'); // or whatever is the name of the sheet 
var range = sheet.getRange(1,1); 
var data = range.getValue();

}

The hierarchy is Spreadsheet --> Sheet --> Range --> Cell.

Heredoc may be an option, see example 2 here: http://php.net/manual/en/language.types.string.php

I was curious if I could beat the accepted answer's time with a one line stringify approach:

I tried 5 methods, none previously mentioned - all one liner - all producing correct answers - and I couldn't come close.

So... to save you the trouble and perhaps fulfill curiosity:

import json
import yaml
import time
from ast import literal_eval as literal

def merge_two_dicts(x, y):
    z = x.copy()   # start with x's keys and values
    z.update(y)    # modifies z with y's keys and values & returns None
    return z

x = {'a':1, 'b': 2}
y = {'b':10, 'c': 11}

start = time.time()
for i in range(10000):
    z = yaml.load((str(x)+str(y)).replace('}{',', '))
elapsed = (time.time()-start)
print (elapsed, z, 'stringify yaml')

start = time.time()
for i in range(10000):
    z = literal((str(x)+str(y)).replace('}{',', '))
elapsed = (time.time()-start)
print (elapsed, z, 'stringify literal')

start = time.time()
for i in range(10000):
    z = eval((str(x)+str(y)).replace('}{',', '))
elapsed = (time.time()-start)
print (elapsed, z, 'stringify eval')

start = time.time()
for i in range(10000):
    z = {k:int(v) for k,v in (dict(zip(
            ((str(x)+str(y))
            .replace('}',' ')
            .replace('{',' ')
            .replace(':',' ')
            .replace(',',' ')
            .replace("'",'')
            .strip()
            .split('  '))[::2], 
            ((str(x)+str(y))
            .replace('}',' ')
            .replace('{',' ').replace(':',' ')
            .replace(',',' ')
            .replace("'",'')
            .strip()
            .split('  '))[1::2]
             ))).items()}
elapsed = (time.time()-start)
print (elapsed, z, 'stringify replace')

start = time.time()
for i in range(10000):
    z = json.loads(str((str(x)+str(y)).replace('}{',', ').replace("'",'"')))
elapsed = (time.time()-start)
print (elapsed, z, 'stringify json')

start = time.time()
for i in range(10000):
    z = merge_two_dicts(x, y)
elapsed = (time.time()-start)
print (elapsed, z, 'accepted')

results:

7.693928956985474 {'c': 11, 'b': 10, 'a': 1} stringify yaml

0.005082368850708008 {'c': 11, 'b': 10, 'a': 1} accepted

What I did learn from this is that JSON approach is the fastest way (of those attempted) to return a dictionary from string-of-dictionary; much faster (about 1/4th of the time) of what I considered to be the normal method using ast. I also learned that, the YAML approach should be avoided at all cost.

Yes, I understand that this is not the best/correct way. I was curious if it was faster, and it isn't; I posted to prove it so.

for docker-compose you can try just add

network_mode: "host"

example :

version: '2'
services:
  feedx:
    build: web
    ports:
    - "127.0.0.1:8000:8000"
    network_mode: "host"

https://docs.docker.com/compose/compose-file/#network_mode

The TableModel behind the JTable handles all of the data behind the table. In order to add and remove rows from a table, you need to use a DefaultTableModel

To create the table with this model:

JTable table = new JTable(new DefaultTableModel(new Object[]{"Column1", "Column2"}));

To add a row:

DefaultTableModel model = (DefaultTableModel) table.getModel();
model.addRow(new Object[]{"Column 1", "Column 2", "Column 3"});

You can also remove rows with this method.

Full details on the DefaultTableModel can be found here

This this, it worked for me:

Style:

.pagination {
  display: flex;
  justify-content: center;
}

.pagination li {
  display: block;
 }

And blade:

<div class="pagination">                                              
  {{ $myCollection->render() }}
</div>

HTML Code:-

<input type="text" name="txt1" id="txt1" onkeypress="return AddKeyPress(event);" />      

<input type="button" id="btnclick">

Java Script Code

function AddKeyPress(e) { 
        // look for window.event in case event isn't passed in
        e = e || window.event;
        if (e.keyCode == 13) {
            document.getElementById('btnEmail').click();
            return false;
        }
        return true;
    }

Your Form do not have Default Submit Button

Some ideas:

1. Maybe you could simply not inherit from the parent in that case (and declare a dependency on base with the exclusion). Not handy if you have lot of stuff in the parent pom.

2. Another thing to test would be to declare the mail artifact with the version required by ALL-DEPS under the dependencyManagement in the parent pom to force the convergence (although I'm not sure this will solve the scoping problem).

<dependencyManagement>
  <dependencies>
    <dependency>    
      <groupId>javax.mail</groupId>
      <artifactId>mail</artifactId>
      <version>???</version><!-- put the "right" version here -->
    </dependency>
  </dependencies>
</dependencyManagement>

1. Or you could exclude the mail dependency from log4j if you're not using the features relying on it (and this is what I would do):

<dependency>
  <groupId>log4j</groupId>
  <artifactId>log4j</artifactId>
  <version>1.2.15</version>
  <scope>provided</scope>
  <exclusions>
    <exclusion>
      <groupId>javax.mail</groupId>
      <artifactId>mail</artifactId>
    </exclusion>
    <exclusion>
      <groupId>javax.jms</groupId>
      <artifactId>jms</artifactId>
    </exclusion>
    <exclusion>
      <groupId>com.sun.jdmk</groupId>
      <artifactId>jmxtools</artifactId>
    </exclusion>
    <exclusion>
      <groupId>com.sun.jmx</groupId>
      <artifactId>jmxri</artifactId>
    </exclusion>
  </exclusions>
</dependency>

1. Or you could revert to the version 1.2.14 of log4j instead of the heretic 1.2.15 version (why didn't they mark the above dependencies as optional?!).

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(response.GetResponseStream());
string rootNode = XmlDoc.ChildNodes[0].Name;

I also see that the page loading (performance) takes a long time on using h:commandLink than h:link. h:link is faster compared to h:commandLink

Type "msg /?" in the command prompt to get various ways of sending meessages to a user.

Type "net send /?" in the command prompt to get another variation of sending messages across.

Dictionaries themselves do not have ordered items as such, should you want to print them etc to some order, here are some examples:

In Python 2.4 and above:

mydict = {'carl':40,
          'alan':2,
          'bob':1,
          'danny':3}

for key in sorted(mydict):
    print "%s: %s" % (key, mydict[key])

gives:

alan: 2
bob: 1
carl: 40
danny: 3

(Python below 2.4:)

keylist = mydict.keys()
keylist.sort()
for key in keylist:
    print "%s: %s" % (key, mydict[key])

If you want the app to use the system default proxy, add this to your Application.exe.config (where application.exe is the name of your application):

<system.net>
   <defaultProxy enabled="true" useDefaultCredentials="true">
   <proxy usesystemdefault="true" bypassonlocal="true" />
   </defaultProxy>
</system.net>

there are four types of strings available in php. They are single quotes ('), double quotes (") and Nowdoc (<<<'EOD') and heredoc(<<<EOD) strings

you can use both single quotes and double quotes inside heredoc string. Variables will be expanded just as double quotes.

nowdoc strings will not expand variables just like single quotes.
