JFrame and JApplet are top level containers. If you wish to create a desktop application, you will use JFrame and if you plan to host your application in browser you will use JApplet.

JComponent is an abstract class for all Swing components and you can use it as the base class for your new component. JPanel is a simple usable component you can use for almost anything.

Since this is for a fun project, the simplest way for you is to work with JPanel and then host it inside JFrame or JApplet. Netbeans has a visual designer for Swing with simple examples.

I've run into a similar problem many a time, what happens usually for me is that a java file will say it won't compile in the text editor but in the package explorer it will say it's compiling fine.

Sometimes doing a 'rebuild' or 'clean-build' doesn't work, the files don't actually get built (one has to presume that eclipse thinks the files it has are up to date) and when this happens I usually open up the java build path and just move one of my dependencies down/up the pecking order. This forces eclipse to do a rebuild of everything and it always seems to work.

If you're still having problems try copying the project and seeing if you get the same behaviour and at a last ditch attempt post a bug for eclipse, it may take a while for them to fix but at least you know that you're being heard.

Note that %in% returns a logical vector of TRUE and FALSE. To negate it, you can use ! in front of the logical statement:

SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean, 
 !where_case_travelled_1 %in% 
   c('Outside Canada','Outside province/territory of residence but within Canada'))

Regarding your original approach with -c(...), - is a unary operator that "performs arithmetic on numeric or complex vectors (or objects which can be coerced to them)" (from help("-")). Since you are dealing with a character vector that cannot be coerced to numeric or complex, you cannot use -.

Sometimes, even when the file is in the right directory, there is still the "file not found" exception. One thing you could do is to drop the text file inside eclipse, where your classes are, on the left side. It is going to ask you if you want to copy, click yes. Sometimes it helps.

First, the error you're getting is due to where you're using the COUNT function -- you can't use an aggregate (or group) function in the WHERE clause.

Second, instead of using a subquery, simply join the table to itself:

SELECT a.pid 
FROM Catalog as a LEFT JOIN Catalog as b USING( pid )
WHERE a.sid != b.sid
GROUP BY a.pid

Which I believe should return only rows where at least two rows exist with the same pid but there is are at least 2 sids. To make sure you get back only one row per pid I've applied a grouping clause.

You'll need to create local variables for those columns, assign them during the select and use them for your conditional tests.

declare @yes_ans int,
        @no_ans int,
        @na_ans int

SELECT @yes_ans = yes_ans, @no_ans = no_ans, @na_ans = na_ans 
    from dbo.qrc_maintally 
    where school_id = @SchoolId

If @yes_ans > @no_ans and @yes_ans > @na_ans 
begin
Set @Final = 'Yes'
end
-- etc.

You can refer to below simple recursive function.

function fib(n){
      if (n <= 2) return 1;
      return fib(n-1) + fib(n-2);
 }

console.log(fib(10)) //55 // Pass on any value to get fibonacci of.

If you came here looking for an answer to this question but not exactly the way the OP meant, ie how do you get multi-line CMD to work in a single line, I have a sort of dangerous answer for you.

Trying to use this with things that actually use piping, like say findstr is quite problematic. The same goes for dealing with elses. But if you just want a multi-line conditional command to execute directly from CMD and not via a batch file, this should do work well.

Let's say you have something like this in a batch that you want to run directly in command prompt:

@echo off
for /r %%T IN (*.*) DO (
    if /i "%%~xT"==".sln" (
        echo "%%~T" is a normal SLN file, and not a .SLN.METAPROJ or .SLN.PROJ file
        echo Dumping SLN file contents
        type "%%~T"
    )
)

Now, you could use the line-continuation carat (^) and manually type it out like this, but warning, it's tedious and if you mess up you can learn the joy of typing it all out again.

Well, it won't work with just ^ thanks to escaping mechanisms inside of parentheses shrug At least not as-written. You actually would need to double up the carats like so:

@echo off ^
More? for /r %T IN (*.sln) DO (^^
More? if /i "%~xT"==".sln" (^^
More? echo "%~T" is a normal SLN file, and not a .SLN.METAPROJ or .SLN.PROJ file^^
More? echo Dumping SLN file contents^^
More? type "%~T"))

Instead, you can be a dirty sneaky scripter from the wrong side of the tracks that don't need no carats by swapping them out for a single pipe (|) per continuation of a loop/expression:

@echo off
for /r %T IN (*.sln) DO if /i "%~xT"==".sln" echo "%~T" is a normal SLN file, and not a .SLN.METAPROJ or .SLN.PROJ file | echo Dumping SLN file contents | type "%~T"

In Java an array has a fixed size (after initialisation), meaning that you can't add or remove items from an array.

int[] i = new int[10];

The above snippet mean that the array of integers has a length of 10. It's not possible add an eleventh integer, without re-assign the reference to a new array, like the following:

int[] i = new int[11];

In Java the package java.util contains all kinds of data structures that can handle adding and removing items from array-like collections. The classic data structure Stack has methods for push and pop.

If you don't want to group, then use the following method:

db.collection.aggregate( [ { $match : { score : { $gt : 70, $lte : 90 } } }, { $count: 'count' } ] );

An answer you didn't ask for that may be helpful, if you're doing the replacement in preparation for sending the string into alert() -- or anything else where a single quote character might trip you up.

str.replace("'",'\x27')

That will replace all single quotes with the hex code for single quote.

Try this.

view.animate()
    .translationY(0)
    .alpha(0.0f)
    .setListener(new AnimatorListenerAdapter() {
        @Override
        public void onAnimationEnd(Animator animation) {
            super.onAnimationEnd(animation);
            view.setVisibility(View.GONE);
        }
    });

You can write that in single line, but it's not something that someone would be able to read. Keep it like you already wrote it, it's already beautiful by itself.

If you have too much if/else constructs, you may think about using of different datastructures, like Dictionaries (to look up keys) or Collection (to run conditional LINQ queries on it)

I tried this and got a ';'-delimited csv file:

--#SET TERMINATOR % 
EXPORT TO result.csv OF DEL MODIFIED BY CHARDEL;
SELECT * FROM A

In my case, it was due to Same Origin policies. To explain it further, MDN states the following:

If the iframe and the iframe's parent document are Same Origin, returns a Document (that is, the active document in the inline frame's nested browsing context), else returns null.

Set your PYTHONPATH environment variable. For example like this PYTHONPATH=.:.. (for *nix family).

Also you can manually add your current directory (src in your case) to pythonpath:

import os
import sys
sys.path.insert(0, os.getcwd())

Enumerable.First returns the element instead of an index. In both cases you will get an exception if no matching element appears in the list (your original code will throw an IndexOutOfBoundsException when you try to get the item at index -1, but First will throw an InvalidOperationException).

MyList.First(item => string.Equals("foo", item.name)).value

For cases like the one you described, I found this to work. It's relatively short and sweet:

 let attributedString = NSMutableAttributedString(string: "follow the yellow brick road") //can essentially come from a textField.text as well (will need to unwrap though)
 let text = "follow the yellow brick road"
 let str = NSString(string: text) 
 let theRange = str.rangeOfString("yellow")
 attributedString.addAttribute(NSForegroundColorAttributeName, value: UIColor.yellowColor(), range: theRange)

For normal form you can do

class MyModelForm(forms.ModelForm):
    slug = forms.CharField(widget=forms.HiddenInput())

If you have model form you can do the following

class MyModelForm(forms.ModelForm):
    class Meta:
        model = TagStatus
        fields = ('slug', 'ext')
        widgets = {'slug': forms.HiddenInput()}

You can also override __init__ method

class Myform(forms.Form):
    def __init__(self, *args, **kwargs):
        super(Myform, self).__init__(*args, **kwargs)
        self.fields['slug'].widget = forms.HiddenInput()

I think you're missing something.

Someone has published a docker container / file for this:

https://github.com/vipul-sharma20/docker-opencv3-python3

https://hub.docker.com/r/vipul20/docker-opencv3-python3/~/dockerfile/

You can pull the image directly from docker hub or follow the instructions in the Dockerfile to install.

This issue is really an annoying one. Since you can't add/copy any file outside the dockerfile context, which means it's impossible to just link ~/.ssh/id_rsa into image's /root/.ssh/id_rsa, and when you definitely need a key to do some sshed thing like git clone from a private repo link..., during the building of your docker image.

Anyways, I found a solution to workaround, not so persuading but did work for me.

1. in your dockerfile:

   • add this file as /root/.ssh/id_rsa
   • do what you want, such as git clone, composer...
   • rm /root/.ssh/id_rsa at the end

2. a script to do in one shoot:

   • cp your key to the folder holding dockerfile
   • docker build
   • rm the copied key

3. anytime you have to run a container from this image with some ssh requirements, just add -v for the run command, like:

   docker run -v ~/.ssh/id_rsa:/root/.ssh/id_rsa --name container image command

This solution results in no private key in both you project source and the built docker image, so no security issue to worry about anymore.

Position your <div> absolutely at the bottom and don't forget to give div.A a position: relative - http://jsfiddle.net/TTaMx/

    .A {
        position: relative;
        margin: 40px 0;
        height: 40px;
        width: 200px;
        background: #eee;
    }

    .A:after {
        content: " ";
        display: block;
        background: #c00;
        height: 29px;
        width: 100%;

        position: absolute;
        bottom: -29px;
    }?

I had trouble for a number of days and was hacking around. This link proved out to be extremely helpful for me. It helped me to do a successful upgrade of the SSL on MAC OS X 9.

Based on dirkgently's answer, but fixing his two bugs, and always printing a fixed number of digits:

void printbits(unsigned char v) {
  int i; // for C89 compatability
  for(i = 7; i >= 0; i--) putchar('0' + ((v >> i) & 1));
}

Continuing from Pete's example above, to do it directly in the cmd window, use a single %, eg:

cd c:\test\folder A
for %X in (*)do echo %~nxX

(Note that special files like desktop.ini will not show up.)

It's also possible to redirect the output to a file using >>:

cd c:\test\folder A
for %X in (*)do echo %~nxX>>c:\test\output.txt

For a real example, assuming you want to robocopy all files from folder-A to folder-B (non-recursively):

cd c:\test\folder A
for %X in (*)do robocopy . "c:\test\folder B" "%~nxX" /dcopy:dat /copyall /v>>c:\test\output.txt

and for all folders (recursively):

cd c:\test\folder A
for /d %X in (*)do robocopy "%X" "C:\test\folder B\%X" /e /copyall /dcopy:dat /v>>c:\test\output2.txt

on Ubuntu Bionic (18.04), six is already install for python2 and python3 but I have the error launching Wammu. @3ygun solution worked for me to solve

ImportError: No module named six

when launching Wammu

If it's occurred for python3 program, six come with

pip3 install six

and if you don't have pip3:

apt install python3-pip

with sudo under Ubuntu!

All the answers above are correct, but when I use windows and disable the Prettier ESLint extension rvest.vs-code-prettier-eslint the issue will be fixed.

The most straigthforward way that makes full use of the huge TimeZone Database of Java and is correct:

long currentTime = new Date().getTime();
long dateOnly = currentTime + TimeZone.getDefault().getOffset(currentTime);

You want to edit this file: "\xampp\phpMyAdmin\config.inc.php"

change this line:

$cfg['Servers'][$i]['password'] = 'WhateverPassword';

to whatever your password is. If you don't remember your password, then run this command within the Shell:

mysqladmin.exe -u root password WhateverPassword

where WhateverPassword is your new password.

You can also try:

function getTagValue($string, $tag)
{
    $pattern = "/<{$tag}>(.*?)<\/{$tag}>/s";
    preg_match($pattern, $string, $matches);
    return isset($matches[1]) ? $matches[1] : '';
}

It returns empty string in case of no match.

I realized that this problem was a common problem for some of us, so I published my own solution using nuget package. Below you can see how it works. I hope that will be useful.

Note:This nuget package is my first package. So if you see a mistake, please give feedback. Thank you.

1. Install Package or download source code and add your Project

   -Install-Package Betalgo.MvcMenuNavigator
   

2. Add your pages to an enum

   public enum HeaderTop
   {
       Dashboard,
       Product
   }
   public enum HeaderSub
   {
       Index
   }
   

3. Put Filter to top of your Controllor or Action

   [MenuNavigator(HeaderTop.Product, HeaderSub.Index)]
   public class ProductsController : Controller
   {
       public async Task<ActionResult> Index()
       {
           return View();
       }
   
       [MenuNavigator(HeaderTop.Dashboard, HeaderSub.Index)]
       public async Task<ActionResult> Dashboard()
       {
           return View();
       }
   }
   

4. And use it In your header layout like this

   @{
   var headerTop = (HeaderTop?)MenuNavigatorPageDataNavigatorPageData.HeaderTop;
   var headerSub = (HeaderSub?)MenuNavigatorPageDataNavigatorPageData.HeaderSub;
   }
   <div class="nav-collapse collapse navbar-collapse navbar-responsive-collapse">
   <ul class="nav navbar-nav">
       <li class="@(headerTop==HeaderTop.Dashboard?"active selected open":"")">
           <a href="@Url.Action("Index","Home")">Dashboard</a>
       </li>
       <li class="@(headerTop==HeaderTop.Product?"active selected open":"")">
           <a href="@Url.Action("Index", "Products")">Products</a>
       </li>
   </ul>

You can use this simple 'inline' method to construct a string_list_type parameter (works in SQL Server 2014):

declare @p1 dbo.string_list_type
insert into @p1 values(N'myFirstString')
insert into @p1 values(N'mySecondString')

Example use when executing a stored proc:

exec MyStoredProc @MyParam=@p1

when you perform a test, you ever have the probabilty to reject the null hypothesis when it is true.

See the nextt R code:

p=function(n){
  x=rnorm(n,0,1)
  s=shapiro.test(x)
  s$p.value
}

rep1=replicate(1000,p(5))
rep2=replicate(1000,p(100))
plot(density(rep1))
lines(density(rep2),col="blue")
abline(v=0.05,lty=3)

The graph shows that whether you have a sample size small or big a 5% of the times you have a chance to reject the null hypothesis when it s true (a Type-I error)

$('#datepicker').datepicker().on('show', function () {
                var modal = $('#datepicker').closest('.modal');
                var datePicker = $('body').find('.datepicker');
                if (!modal.length) {
                    $(datePicker).css('z-index', 'auto');
                    return;
                }
                var zIndexModal = $(modal).css('z-index');
                $(datePicker).css('z-index', zIndexModal + 1);
            });

After working all day on this, I finally found a solution. Here's how I send from Windows XP with WAMP.

1. Use Google's SMTP server. You probably need an account.
2. Download and install Fake Sendmail. I just downloaded it, unzipped it and put it in the WAMP folder.
3. Create a test PHP file. See below.

<?php
    $message = "test message body";
    $result = mail('[email protected]', 'message subject', $message);
    echo "result: $result";
?>

4. Update your php.ini file and your sendmail.ini file (sendmail.ini is in the sendmail folder).
5. Check the error.log file in the sendmail folder that you just created if it doesn't work.

After years of ugly string parsing, there's a better way: URLSearchParams Let's have a look at how we can use this new API to get values from the location!

//Assuming URL has "?post=1234&action=edit"

var urlParams = new URLSearchParams(window.location.search);
console.log(urlParams.has('post')); // true
console.log(urlParams.get('action')); // "edit"
console.log(urlParams.getAll('action')); // ["edit"]
console.log(urlParams.toString()); // "?post=1234&action=edit"
console.log(urlParams.append('active', '1')); // "?

post=1234&action=edit&active=1"

UPDATE : IE is not supported

use this function from an answer below instead of URLSearchParams

$.urlParam = function (name) {
    var results = new RegExp('[\?&]' + name + '=([^&#]*)')
                      .exec(window.location.search);

    return (results !== null) ? results[1] || 0 : false;
}

console.log($.urlParam('action')); //edit

push is a native javascript method. You could use it like this:

var array = [1, 2, 3];
array.push(4); // array now is [1, 2, 3, 4]
array.push(5, 6, 7); // array now is [1, 2, 3, 4, 5, 6, 7]

.gitattributes - is a root-level file of your repository that defines the attributes for a subdirectory or subset of files.

You can specify the attribute to tell Git to use different merge strategies for a specific file. Here, we want to preserve the existing config.xml for our branch. We need to set the merge=foo to config.xml in .gitattributes file.

merge=foo tell git to use our(current branch) file, if a merge conflict occurs.

1. Add a .gitattributes file at the root level of the repository

2. You can set up an attribute for confix.xml in the .gitattributes file

    <pattern> merge=foo
   

   Let's take an example for config.xml

    config.xml merge=foo
   

3. And then define a dummy foo merge strategy with:

    $ git config --global merge.foo.driver true
   

If you merge the stag form dev branch, instead of having the merge conflicts with the config.xml file, the stag branch's config.xml preserves at whatever version you originally had.

I use new Date().getTime(), which will avoid collisions unless you have multiple requests happening within the same millisecond:

$.get('/getdata?_=' + new Date().getTime(), function(data) {
    console.log(data); 
});

Edit: This answer is several years old. It still works (hence I haven't deleted it), but there are better/cleaner ways of achieving this now. My preference is for this method, but this answer is also useful if you want to disable caching for every request during the lifetime of a page.

Use this code

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

    <corners
        android:bottomLeftRadius="5dp"
        android:bottomRightRadius="5dp"
        android:radius="0.1dp"
        android:topLeftRadius="5dp"
        android:topRightRadius="5dp" />

    <solid android:color="#Efffff" />

    <stroke
        android:width="2dp"
        android:color="#25aaff" />

</shape>

Nothing like these two lines appears in Mike Williams' tutorial:

    wait = true;
    setTimeout("wait = true", 2000);

Here's a Version 3 port:

http://acleach.me.uk/gmaps/v3/plotaddresses.htm

The relevant bit of code is

  // ====== Geocoding ======
  function getAddress(search, next) {
    geo.geocode({address:search}, function (results,status)
      { 
        // If that was successful
        if (status == google.maps.GeocoderStatus.OK) {
          // Lets assume that the first marker is the one we want
          var p = results[0].geometry.location;
          var lat=p.lat();
          var lng=p.lng();
          // Output the data
            var msg = 'address="' + search + '" lat=' +lat+ ' lng=' +lng+ '(delay='+delay+'ms)<br>';
            document.getElementById("messages").innerHTML += msg;
          // Create a marker
          createMarker(search,lat,lng);
        }
        // ====== Decode the error status ======
        else {
          // === if we were sending the requests to fast, try this one again and increase the delay
          if (status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
            nextAddress--;
            delay++;
          } else {
            var reason="Code "+status;
            var msg = 'address="' + search + '" error=' +reason+ '(delay='+delay+'ms)<br>';
            document.getElementById("messages").innerHTML += msg;
          }   
        }
        next();
      }
    );
  }

WHERE clause introduces a condition on individual rows; HAVING clause introduces a condition on aggregations, i.e. results of selection where a single result, such as count, average, min, max, or sum, has been produced from multiple rows. Your query calls for a second kind of condition (i.e. a condition on an aggregation) hence HAVING works correctly.

As a rule of thumb, use WHERE before GROUP BY and HAVING after GROUP BY. It is a rather primitive rule, but it is useful in more than 90% of the cases.

While you're at it, you may want to re-write your query using ANSI version of the join:

SELECT  L.LectID, Fname, Lname
FROM Lecturers L
JOIN Lecturers_Specialization S ON L.LectID=S.LectID
GROUP BY L.LectID, Fname, Lname
HAVING COUNT(S.Expertise)>=ALL
(SELECT COUNT(Expertise) FROM Lecturers_Specialization GROUP BY LectID)

This would eliminate WHERE that was used as a theta join condition.

This should work fine.

    style.setFillPattern(CellStyle.SOLID_FOREGROUND);
    style.setAlignment(CellStyle.ALIGN_CENTER);

If you do not create defaultFont all your workbook will be using the other one as default.

On .Net Core 3.1 we just need to do these:

static void Main(string[] args)
{
  var configuration = new ConfigurationBuilder().AddJsonFile("appsettings.json").Build();
}

Using SeriLog will look like:

using Microsoft.Extensions.Configuration;
using Serilog;
using System;


namespace yournamespace
{
    class Program
    {

        static void Main(string[] args)
        {
            var configuration = new ConfigurationBuilder().AddJsonFile("appsettings.json").Build();
            Log.Logger = new LoggerConfiguration().ReadFrom.Configuration(configuration).CreateLogger();

            try
            {
                Log.Information("Starting Program.");
            }
            catch (Exception ex)
            {
                Log.Fatal(ex, "Program terminated unexpectedly.");
                return;
            }
            finally
            {
                Log.CloseAndFlush();
            }
        }
    }
}

And the Serilog appsetings.json section for generating one file daily will look like:

  "Serilog": {
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Microsoft": "Warning",
        "System": "Warning"
      }
    },
    "Using": [ "Serilog.Sinks.Console", "Serilog.Sinks.File" ],
    "WriteTo": [
      {
        "Name": "File",
        "Args": {
          "path": "C:\\Logs\\Program.json",
          "rollingInterval": "Day",
          "formatter": "Serilog.Formatting.Compact.CompactJsonFormatter, Serilog.Formatting.Compact"
        }
      }
    ]
  }

Just use:

<?php
    include("/path/to/file.html");
?>

That will echo it as well. This also has the benefit of executing any PHP in the file.

If you need to do anything with the contents, use file_get_contents(),

For example,

<?php
    $pagecontents = file_get_contents("/path/to/file.html");

    echo str_replace("Banana", "Pineapple", $pagecontents);

?>

This doesn't execute code in that file, so be careful if you expect that to work.

I usually use:

include($_SERVER['DOCUMENT_ROOT']."/path/to/file/as/in/url.html");

as then I can move files without breaking the includes.

A minor addition to the answers already posted: object files not compiled to be position independent are relocatable; they contain relocation table entries.

These entries allow the loader (that bit of code that loads a program into memory) to rewrite the absolute addresses to adjust for the actual load address in the virtual address space.

An operating system will try to share a single copy of a "shared object library" loaded into memory with all the programs that are linked to that same shared object library.

Since the code address space (unlike sections of the data space) need not be contiguous, and because most programs that link to a specific library have a fairly fixed library dependency tree, this succeeds most of the time. In those rare cases where there is a discrepancy, yes, it may be necessary to have two or more copies of a shared object library in memory.

Obviously, any attempt to randomize the load address of a library between programs and/or program instances (so as to reduce the possibility of creating an exploitable pattern) will make such cases common, not rare, so where a system has enabled this capability, one should make every attempt to compile all shared object libraries to be position independent.

Since calls into these libraries from the body of the main program will also be made relocatable, this makes it much less likely that a shared library will have to be copied.

Many times if your radio buttons belong to the same radioGroup then

radioButton.setChecked(true)

will not select the radio button properly. So to solve this problem try using your radioGroup.

radioGroup.check(R.id.radioButtonId)

Here is how it works for me with no Servlet use.

Let's say I am trying to access web.xml in project/WebContent/WEB-INF/web.xml

1. In project property Source-tab add source folder by pointing to the parent container for WEB-INF folder (in my case WebContent )

2. Now let's use class loader:

   InputStream inStream = class.getClass().getClassLoader().getResourceAsStream("Web-INF/web.xml")
   

You can use GNU Parallel for this as it works as a mutex when called as sem. So, in concrete terms, you can use:

sem --id SCRIPTSINGLETON yourScript

If you want a timeout too, use:

sem --id SCRIPTSINGLETON --semaphoretimeout -10 yourScript

Timeout of <0 means exit without running script if semaphore is not released within the timeout, timeout of >0 mean run the script anyway.

Note that you should give it a name (with --id) else it defaults to the controlling terminal.

GNU Parallel is a very simple install on most Linux/OSX/Unix platforms - it is just a Perl script.

When from . import * isn't good enough, this is an improvement over the answer by ted. Specifically, the use of __all__ is not necessary with this approach.

"""Import all modules that exist in the current directory."""
# Ref https://stackoverflow.com/a/60861023/
from importlib import import_module
from pathlib import Path

for f in Path(__file__).parent.glob("*.py"):
    module_name = f.stem
    if (not module_name.startswith("_")) and (module_name not in globals()):
        import_module(f".{module_name}", __package__)
    del f, module_name
del import_module, Path

Note that module_name not in globals() is intended to avoid reimporting the module if it's already imported, as this can risk cyclic imports.

\n\r seems working for me.

I am using Xcode 4.6 with IOS 6.0 as target. Tested on iPhone 4S. Try it by yourself.

There is a simple trick for this. After you constructed the frame with all it buttons do this:

frame.getRootPane().setDefaultButton(submitButton);

For each frame, you can set a default button that will automatically listen to the Enter key (and maybe some other event's I'm not aware of). When you hit enter in that frame, the ActionListeners their actionPerformed() method will be invoked.

And the problem with your code as far as I see is that your dialog pops up every time you hit a key, because you didn't put it in the if-body. Try changing it to this:

@Override
public void keyPressed(KeyEvent e) {
    if (e.getKeyCode()==KeyEvent.VK_ENTER){
        System.out.println("Hello");

        JOptionPane.showMessageDialog(null , "You've Submitted the name " + nameInput.getText());
    }

}

UPDATE: I found what is wrong with your code. You are adding the key listener to the Submit button instead of to the TextField. Change your code to this:

SubmitButton listener = new SubmitButton(textBoxToEnterName);
textBoxToEnterName.addActionListener(listener);
submit.addKeyListener(listener);

in laravel 5 first we need to create migration and then run the migration

Step 1.

php artisan make:migration create_users_table --create=users

Step 2.

php artisan migrate

Give the same name in urls.py

 path('detail/<int:id>', views.detail, name="detail"),

I believe that you can omit updating the "non-desired" columns by adjusting the other answers as follows:

update table set
    columnx = (case when condition1 then 25 end),
    columny = (case when condition2 then 25 end)`

As I understand it, this will update only when the condition is met.

After reading all the comments, this is the most efficient:

Update table set ColumnX = 25 where Condition1
 Update table set ColumnY = 25 where Condition1`

Sample Table:

CREATE TABLE [dbo].[tblTest](
    [ColX] [int] NULL,
    [ColY] [int] NULL,
    [ColConditional] [bit] NULL,
    [id] [int] IDENTITY(1,1) NOT NULL
) ON [PRIMARY]

Sample Data:

Insert into tblTest (ColX, ColY, ColConditional) values (null, null, 0)
Insert into tblTest (ColX, ColY, ColConditional) values (null, null, 0)
Insert into tblTest (ColX, ColY, ColConditional) values (null, null, 1)
Insert into tblTest (ColX, ColY, ColConditional) values (null, null, 1)
Insert into tblTest (ColX, ColY, ColConditional) values (1, null, null)
Insert into tblTest (ColX, ColY, ColConditional) values (2, null, null)
Insert into tblTest (ColX, ColY, ColConditional) values (null, 1, null)
Insert into tblTest (ColX, ColY, ColConditional) values (null, 2, null)

Now I assume you can write a conditional that handles nulls. For my example, I am assuming you have written such a conditional that evaluates to True, False or Null. If you need help with this, let me know and I will do my best.

Now running these two lines of code does infact change X to 25 if and only if ColConditional is True(1) and Y to 25 if and only if ColConditional is False(0)

Update tblTest set ColX = 25 where ColConditional = 1
Update tblTest set ColY = 25 where ColConditional = 0

P.S. The null case was never mentioned in the original question or any updates to the question, but as you can see, this very simple answer handles them anyway.

This is a very common case in DataTables when it's not able to find the request field define in DataTable configuration.
For Example:

                "aoColumns": [{
                    mData: 'mobile', sWidth: "149px;"
               }, {
                    mData: 'name', sWidth: "121px;"
               }, {
                    mData: 'productName', sWidth: "116px;"
                            }
            }];

Here, If DataTable doesn't receive above mentioned properties. It'll generate this warning:

DataTables warning: Requested unknown parameter '0' from the data source for row '0'

To overcome this you just need to simply set a default value in "aoColumns"

For Example:

  "aoColumns": [{
                mData: 'mobile',sDefaultContent :  '',sWidth: "149px;"
           }, {
                mData: 'name',sDefaultContent :  '', sWidth: "121px;"
           }, {
                mData: 'productName',sDefaultContent :  '', sWidth: "116px;"
              }
        }];

sDefaultContent will supress the warning.
Note: This property could be changed based on version of dataTables you are using.

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

Restarting Android Studio fix the issue for me.

That means that the definition of your function is not present in your program. You forgot to add that one.cpp to your program.

What "to add" means in this case depends on your build environment and its terminology. In MSVC (since you are apparently use MSVC) you'd have to add one.cpp to the project.

In more practical terms, applicable to all typical build methodologies, when you link you program, the object file created form one.cpp is missing.

Based on the title, we can generate strong SHA hashes, in a browser context, it can be used to generate a unique hash from an object, an array of params, a string, or whatever.

async function H(m) {
  const msgUint8 = new TextEncoder().encode(m)                       
  const hashBuffer = await crypto.subtle.digest('SHA-256', msgUint8)          
  const hashArray = Array.from(new Uint8Array(hashBuffer))                    
  const hashHex = hashArray.map(b => b.toString(16).padStart(2, '0')).join('')
  console.log(hashHex)
}

/* Examples ----------------------- */
H("An obscure ....")
H(JSON.stringify( {"hello" : "world"} ))
H(JSON.stringify( [54,51,54,47] ))

Save any variable that want to be shared as one object. Then pass it to loaded module so it could access the variable through object reference..

// main.js
var myModule = require('./module.js');
var shares = {value:123};

// Initialize module and pass the shareable object
myModule.init(shares);

// The value was changed from init2 on the other file
console.log(shares.value); // 789

On the other file..

// module.js
var shared = null;

function init2(){
    console.log(shared.value); // 123
    shared.value = 789;
}

module.exports = {
    init:function(obj){
        // Save the shared object on current module
        shared = obj;

        // Call something outside
        init2();
    }
}

There's no need, just use fadeToggle() on the element:

$('#testElement').fadeToggle('fast');

Here's a demo.

The syntax for providing a single value can be confusing for inexperienced Python users.

Given the query

INSERT INTO mytable (fruit) VALUES (%s)

The value passed to cursor.execute must still be a tuple even though it is a singleton, so we must provide a single element tuple, like this: (value,).

cursor.execute("""INSERT INTO mytable (fruit) VALUES (%s)""", ('apple',))

'dir' is an alias for Get-ChildItem which will return back a System.IO.FileInfo class when you're calling it from the filesystem which has VersionInfo as a property. So ...

To get the version info of a single file do this:

PS C:\Windows> (dir .\write.exe).VersionInfo | fl

Edit the config file with in ".git" folder to maintain the different username and email depends upon the repository

• Go to Your repository
• Show the hidden files and go to ".git" folder
• Find the "config" file
• Add the below lines at EOF

[user]

name = Bob

email = [email protected]

This below command show you which username and email set for this repository.

git config --get user.name

git config --get user.email

Example: for mine that config file in D:\workspace\eclipse\ipchat\.git\config

Here ipchat is my repo name

Make use of the log10 function to determine the number of digits and do like below:

char * toArray(int number)
{
    int n = log10(number) + 1;
    int i;
    char *numberArray = calloc(n, sizeof(char));
    for (i = n-1; i >= 0; --i, number /= 10)
    {
        numberArray[i] = (number % 10) + '0';
    }
    return numberArray;
}

Or the other option is sprintf(yourCharArray,"%ld", intNumber);

As of Django 1.2, you can use exists():

https://docs.djangoproject.com/en/dev/ref/models/querysets/#exists

if some_queryset.filter(pk=entity_id).exists():
    print("Entry contained in queryset")

This works too

 var i = 1;_x000D_
 $('button').click(function() {_x000D_
     $('#red').clone().appendTo('#test').prop('id', 'red' + i);_x000D_
     i++; _x000D_
 });

This problem was created by a regression in a recent release. You can find the pull request that fixes this problem at https://github.com/facebook/react-native-fbsdk/pull/339

You don't have to handcode this. The problem definition is precisely the behavior of Apache Commons CollectionUtils#collate. It's also overloaded for different sort orders and allowing duplicates.

This code is from http://andylangton.co.uk/articles/javascript/get-viewport-size-javascript/

function viewport() {
    var e = window, a = 'inner';
    if (!('innerWidth' in window )) {
        a = 'client';
        e = document.documentElement || document.body;
    }
    return { width : e[ a+'Width' ] , height : e[ a+'Height' ] };
}

NB : to read the width, use console.log('viewport width'+viewport().width);

The best way to do, I think, is to handle it like the MSDN said on http://msdn.microsoft.com/en-us/library/system.windows.forms.control.previewkeydown.aspx

But handle it, how you really need it. My way (in the example below) is to catch every KeyDown ;-)

    /// <summary>
    /// onPreviewKeyDown
    /// </summary>
    /// <param name="e"></param>
    protected override void OnPreviewKeyDown(PreviewKeyDownEventArgs e)
    {
        e.IsInputKey = true;
    }

    /// <summary>
    /// onKeyDown
    /// </summary>
    /// <param name="e"></param>
    protected override void OnKeyDown(KeyEventArgs e)
    {
        Input.SetFlag(e.KeyCode);
        e.Handled = true;
    }

    /// <summary>
    /// onKeyUp
    /// </summary>
    /// <param name="e"></param>
    protected override void OnKeyUp(KeyEventArgs e)
    {
        Input.RemoveFlag(e.KeyCode);
        e.Handled = true;
    }

A string is one string, a string[] is a string array. It means it's a variable with multiple strings in it.

Although you can convert a string to a string[] (create a string array with one element in it), it's probably a sign that you're trying to do something which you shouldn't do.

Little bit cleared @A.Morel's answer. You might beware of keyboard language layout. Some keyboard layouts changed default numeric keys to symbols.

let key = parseInt(e.key)
if (isNaN(key)) {
  console.log("is not numeric")
}
else {
  console.log("is numeric")
}

Usually I will clone the initial repository first, and then move everything in the existing folder to the initial repository. It works every time.

The advantage of this method is that you won't missing anything of the initial repository including README or .gitignore.

You can also use the command below to finish the steps:

$ git clone https://github.com/your_repo.git && mv existing_folder/* your_repo

In my point of view,

If you dont use Integrated security=SSPI,then you need to hardcode the username and password in the connection string which means "relatively insecure" why because, all the employees have the access even ex-employee could use the information maliciously.

This means your nested SELECT returns more than one rows.

You need to add a proper WHERE clause to it.

The syntax for creating a new table is

CREATE TABLE new_table
AS
SELECT *
  FROM old_table

This will create a new table named new_table with whatever columns are in old_table and copy the data over. It will not replicate the constraints on the table, it won't replicate the storage attributes, and it won't replicate any triggers defined on the table.

SELECT INTO is used in PL/SQL when you want to fetch data from a table into a local variable in your PL/SQL block.

Following query is useful and simple-

declare @floatExchRate float;
set @floatExchRate=(select convert(decimal(10, 2), 0.2548712))
select  @floatExchRate

Gives output as 0.25.

The other answers didn't quite work for my specific scenario, where I am reading paths that have originated from an OS different to my current one. To elaborate I am saving email attachments saved from a Windows platform on a Linux server. The filename returned from the JavaMail API is something like 'C:\temp\hello.xls'

The solution I ended up with:

String filenameWithPath = "C:\\temp\\hello.xls";
String[] tokens = filenameWithPath.split("[\\\\|/]");
String filename = tokens[tokens.length - 1];

Found an easy way which works with all browsers I have (Chrome 49, Edge 25, Firefox 44, IE11, Safari 5 [Win], Safari 8 (MacOS)) :

// Clean svg content (if you want to update the svg's objects)_x000D_
// Note : .html('') doesn't works for svg in some browsers_x000D_
$('#svgObject').empty();_x000D_
// add some objects_x000D_
$('#svgObject').append('<polygon class="svgStyle" points="10,10 50,10 50,50 10,50 10,10" />');_x000D_
$('#svgObject').append('<circle class="svgStyle" cx="100" cy="30" r="25"/>');_x000D_
_x000D_
// Magic happens here: refresh DOM (you must refresh svg's parent for Edge/IE and Safari)_x000D_
$('#svgContainer').html($('#svgContainer').html());

It appears as though you need to explicitly set a font, and change the line-height and height as needed. Assuming 'Times New Roman' is your browser's default font:

span {_x000D_
  display: inline-block;_x000D_
  font-size: 50px;_x000D_
  background-color: green;_x000D_
  /*new:*/_x000D_
  font-family: 'Times New Roman';_x000D_
  line-height: 34px;_x000D_
  height: 35px;_x000D_
}

<link href='http://fonts.googleapis.com/css?family=Tinos' rel='stylesheet' type='text/css'>_x000D_
<span>_x000D_
    BIG TEXT_x000D_
</span>

HostListener should be the proper way to bind event into your component:

@Component({
  selector: 'your-element'
})

export class YourElement {
  @HostListener('click', ['$event']) onClick(event) {
     console.log('component is clicked');
     console.log(event);
  }
}

grep -q "something" file
[[ !? -eq 0 ]] && echo "yes" || echo "no"

I think flatMap() is what you're looking for.

For example:

 List<AClass> allTheObjects = map.values()
         .stream()
         .flatMap(listContainer -> listContainer.lst.stream())
         .collect(Collectors.toList());

Modernizr doesn't detect browsers as such, it detects which feature and capability are present and this is the whole jist of what it's trying to do.

You could try hooking in a simple detection script like this and then using it to make your choice. I've included Version Detection as well just in case that's needed. If you only want to check of any version of IE you could just look for the navigator.userAgent having a value of "MSIE".

var BrowserDetect = {_x000D_
        init: function () {_x000D_
            this.browser = this.searchString(this.dataBrowser) || "Other";_x000D_
            this.version = this.searchVersion(navigator.userAgent) || this.searchVersion(navigator.appVersion) || "Unknown";_x000D_
        },_x000D_
        searchString: function (data) {_x000D_
            for (var i = 0; i < data.length; i++) {_x000D_
                var dataString = data[i].string;_x000D_
                this.versionSearchString = data[i].subString;_x000D_
_x000D_
                if (dataString.indexOf(data[i].subString) !== -1) {_x000D_
                    return data[i].identity;_x000D_
                }_x000D_
            }_x000D_
        },_x000D_
        searchVersion: function (dataString) {_x000D_
            var index = dataString.indexOf(this.versionSearchString);_x000D_
            if (index === -1) {_x000D_
                return;_x000D_
            }_x000D_
_x000D_
            var rv = dataString.indexOf("rv:");_x000D_
            if (this.versionSearchString === "Trident" && rv !== -1) {_x000D_
                return parseFloat(dataString.substring(rv + 3));_x000D_
            } else {_x000D_
                return parseFloat(dataString.substring(index + this.versionSearchString.length + 1));_x000D_
            }_x000D_
        },_x000D_
_x000D_
        dataBrowser: [_x000D_
            {string: navigator.userAgent, subString: "Edge", identity: "MS Edge"},_x000D_
            {string: navigator.userAgent, subString: "MSIE", identity: "Explorer"},_x000D_
            {string: navigator.userAgent, subString: "Trident", identity: "Explorer"},_x000D_

    BrowserDetect.init();_x000D_
    document.write("You are using <b>" + BrowserDetect.browser + "</b> with version <b>" + BrowserDetect.version + "</b>");

You can then simply check for:

BrowserDetect.browser == 'Explorer';
BrowserDetect.version <= 9;

the right, easy, cool, exact answer for the question is to use %run macro with -d flag.

Data types must match exactly. If you are dealing with varchar types, the tables must use the same collation.

Here's code that may give you ideas:

<style>
.containerdiv { float: left; position: relative; } 
.cornerimage { position: absolute; top: 0; right: 0; } 
</style>

<div class="containerdiv">
    <img border="0" src="https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png" alt=""">
    <img class="cornerimage" border="0" src="http://www.gravatar.com/avatar/" alt="">
<div>

JSFiddle

I suspect that Espo's solution may be inconvenient because it requires you to position both images absolutely. You may want the first one to position itself in the flow.

Usually, there is a natural way to do that is CSS. You put position: relative on the container element, and then absolutely position children inside it. Unfortunately, you cannot put one image inside another. That's why I needed container div. Notice that I made it a float to make it autofit to its contents. Making it display: inline-block should theoretically work as well, but browser support is poor there.

EDIT: I deleted size attributes from the images to illustrate my point better. If you want the container image to have its default sizes and you don't know the size beforehand, you cannot use the background trick. If you do, it is a better way to go.

None of the mentioned answer worked for me.

To resolve this issue i have to follow bellow steps:

• Right click on Java HotSpot(TM) 64 Bit server.
• Select "Edit Source Lookup".
• Click on "Add".
• Select "File System Directory" instead of Java project.
• Select Root directory of your project.
• Check "Search Subfolders".
• Click Ok ok ok.

Thanks.

Edit: As in a comment rightly requested here some more information. Use the include tag

<include
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   layout="@layout/yourlayout" />

to include the layout you want to reuse.

socket.disconnect()

Only reboots the connection firing disconnect event on client side. But gets connected again.

socket.close()

Disconnect the connection from client. The client will keep trying to connect.

In general, if you have your coins COIN[] and your "change range" 1..MAX, the following should find the maximum number of coins.

Initialise array CHANGEVAL[MAX] to -1

For each element coin in COIN:
  set CHANGEVAL[coin] to 1
Until there are no more -1 in CHANGEVAL:
  For each index I over CHANGEVAL:
    if CHANGEVAL[I] != -1:
      let coincount = CHANGEVAL[I]
      For each element coin in COIN:
        let sum = coin + I
        if (COINS[sum]=-1) OR ((coincount+1)<COINS[sum]):
          COINS[sum]=coincount+1

I don't know if the check for coin-minimality in the inner conditional is, strictly speaking, necessary. I would think that the minimal chain of coin-additions would end up being correct, but better safe than sorry.

Actually the last one is not weird. Code is setting the timezone for working instead of working2.

SimpleDateFormat working2 = new SimpleDateFormat("hh:mm:ss"); working.setTimeZone(TimeZone.getTimeZone("Etc/UTC"));

kk goes from 1 to 24, HH from 0 to 23 and hh from 1 to 12 (AM/PM).

Fixing this error gives:

24:00:00
00:00:00
01:00:00

LatLngBounds must be defined with points in (south-west, north-east) order. Your points are not in that order.

The general fix, especially if you don't know the points will definitely be in that order, is to extend an empty bounds:

var bounds = new google.maps.LatLngBounds();
bounds.extend(myPlace);
bounds.extend(Item_1);
map.fitBounds(bounds);

The API will sort out the bounds.

Work for arrays and lists only, not for set.

If you're trying to use this on Cygwin, then you need to follow the instructions in this answer. (It's a problem how Cygwin treats Windows symlinks.)

Try this:

> HISTTIMEFORMAT="%d/%m/%y %T "

> history

You can adjust the format to your liking, of course.

To check for assignability, you can use the Type.IsAssignableFrom method:

typeof(SomeType).IsAssignableFrom(typeof(Derived))

This will work as you expect for type-equality, inheritance-relationships and interface-implementations but not when you are looking for 'assignability' across explicit / implicit conversion operators.

To check for strict inheritance, you can use Type.IsSubclassOf:

typeof(Derived).IsSubclassOf(typeof(SomeType))

import os

dir_path = os.path.dirname(os.path.realpath(__file__))
parent_path = os.path.abspath(os.path.join(dir_path, os.pardir))

$searchfor = $_GET['keyword'];
$file = 'users.txt';

$contents = file_get_contents($file);
$pattern = preg_quote($searchfor, '/');
$pattern = "/^.*$pattern.*\$/m";

if (preg_match_all($pattern, $contents, $matches)) {
    echo "Found matches:<br />";
    echo implode("<br />", $matches[0]);
} else {
    echo "No matches found";
    fclose ($file); 
}

In JavaScript, the type of key/value store you are attempting to use is an object literal, rather than an array. You are mistakenly creating a composite array object, which happens to have other properties based on the key names you provided, but the array portion contains no elements.

Instead, declare valueToPush as an object and push that onto cookie_value_add:

// Create valueToPush as an object {} rather than an array []
var valueToPush = {};

// Add the properties to your object
// Note, you could also use the valueToPush["productID"] syntax you had
// above, but this is a more object-like syntax
valueToPush.productID = productID;
valueToPush.itemColorTitle = itemColorTitle;
valueToPush.itemColorPath = itemColorPath;

cookie_value_add.push(valueToPush);

// View the structure of cookie_value_add
console.dir(cookie_value_add);

There is no command which will change the name of all files generated using the component create command. So created ts, html, css/scss, .spec.ts files need to be manually renamed/edited.

I am a frequent user of angular cli and I think this would be a nice-to-have command as some time we just create angular components and need to rename them. As this rename command is not there, deleting the created angular component, directive, etc and again running the command to create the component is really a pain.

Here is the discussion link to add this feature rename angular component

1. Make sure you have System.Web referenced
2. Get rid of the two } at the end.

Here's a working version. I changed the XmlElementAttribute labels to XmlElement because in the xml the StockNumber, Make and Model values are elements, not attributes. Also I removed the reader.ReadToEnd(); (that function reads the whole stream and returns a string, so the Deserialize() function couldn't use the reader anymore...the position was at the end of the stream). I also took a few liberties with the naming :).

Here are the classes:

[Serializable()]
public class Car
{
    [System.Xml.Serialization.XmlElement("StockNumber")]
    public string StockNumber { get; set; }

    [System.Xml.Serialization.XmlElement("Make")]
    public string Make { get; set; }

    [System.Xml.Serialization.XmlElement("Model")]
    public string Model { get; set; }
}


[Serializable()]
[System.Xml.Serialization.XmlRoot("CarCollection")]
public class CarCollection
{
    [XmlArray("Cars")]
    [XmlArrayItem("Car", typeof(Car))]
    public Car[] Car { get; set; }
}

The Deserialize function:

CarCollection cars = null;
string path = "cars.xml";

XmlSerializer serializer = new XmlSerializer(typeof(CarCollection));

StreamReader reader = new StreamReader(path);
cars = (CarCollection)serializer.Deserialize(reader);
reader.Close();

And the slightly tweaked xml (I needed to add a new element to wrap <Cars>...Net is picky about deserializing arrays):

<?xml version="1.0" encoding="utf-8"?>
<CarCollection>
<Cars>
  <Car>
    <StockNumber>1020</StockNumber>
    <Make>Nissan</Make>
    <Model>Sentra</Model>
  </Car>
  <Car>
    <StockNumber>1010</StockNumber>
    <Make>Toyota</Make>
    <Model>Corolla</Model>
  </Car>
  <Car>
    <StockNumber>1111</StockNumber>
    <Make>Honda</Make>
    <Model>Accord</Model>
  </Car>
</Cars>
</CarCollection>

TLDR:

git pull is like running git fetch then git merge
git pull --rebase is like git fetch then git rebase

In reply to your first statement,

git pull is like a git fetch + git merge.

"In its default mode, git pull is shorthand for git fetch followed by git merge FETCH_HEAD" More precisely, git pull runs git fetch with the given parameters and then calls git merge to merge the retrieved branch heads into the current branch"

(Ref: https://git-scm.com/docs/git-pull)

For your second statement/question:

'But what is the difference between git pull VS git fetch + git rebase'

Again, from same source:
git pull --rebase

"With --rebase, it runs git rebase instead of git merge."

Now, if you wanted to ask

'the difference between merge and rebase'

that is answered here too:
https://git-scm.com/book/en/v2/Git-Branching-Rebasing
(the difference between altering the way version history is recorded)

Use conditional formatting.

You can enter a condition using any cell you like and a format to apply if the formula is true.

When you're going to work with such time series in Python, pandas is indispensable. And here's the good news: it comes with a historical data downloader for Yahoo: pandas.io.data.DataReader.

from pandas.io.data import DataReader
from datetime import datetime

ibm = DataReader('IBM',  'yahoo', datetime(2000, 1, 1), datetime(2012, 1, 1))
print(ibm['Adj Close'])

Here's an example from the pandas documentation.

Update for pandas >= 0.19:

The pandas.io.data module has been removed from pandas>=0.19 onwards. Instead, you should use the separate pandas-datareader package. Install with:

pip install pandas-datareader

And then you can do this in Python:

import pandas_datareader as pdr
from datetime import datetime

ibm = pdr.get_data_yahoo(symbols='IBM', start=datetime(2000, 1, 1), end=datetime(2012, 1, 1))
print(ibm['Adj Close'])

Downloading from Google Finance is also supported.

There's more in the documentation of pandas-datareader.

if you have repository for entity Foo and need to select all entries with exact string value boo (also works for other primitive types or entity types). Put this into your repository interface:

List<Foo> findByBoo(String boo);

if you need to order results:

List<Foo> findByBooOrderById(String boo);

See more at reference.

The genaral form to declare a new array in java is as follows:

type arrayName[] = new type[numberOfElements];

Where type is a primitive type or Object. numberOfElements is the number of elements you will store into the array and this value can’t change because Java does not support dynamic arrays (if you need a flexible and dynamic structure for holding objects you may want to use some of the Java collections).

Lets initialize an array to store the salaries of all employees in a small company of 5 people:

int salaries[] = new int[5];

The type of the array (in this case int) applies to all values in the array. You can not mix types in one array.

Now that we have our salaries array initialized we want to put some values into it. We can do this either during the initialization like this:

int salaries[] = {50000, 75340, 110500, 98270, 39400};

Or to do it at a later point like this:

salaries[0] = 50000;
salaries[1] = 75340;
salaries[2] = 110500;
salaries[3] = 98270;
salaries[4] = 39400;

More visual example of array creation:

Many of these answers mention how to share the project on Git, which is easy, you just share the code on git, but one thing to take note of is that there is no apparent "project file" that the end user can double click on. Instead you have to use Import->General->Existing project and select the whole folder

You can use try catch block here:

s="1234"
try:
    num=int(s)
    print "S contains only digits"
except:
    print "S doesn't contain digits ONLY"

It's been said elaborately, just as "the short answer":

• static variable (class)
  lifetime = program runtime (1)
  visibility = determined by access modifiers (private/protected/public)

• static variable (global scope)
  lifetime = program runtime (1)
  visibility = the compilation unit it is instantiated in (2)

• heap variable
  lifetime = defined by you (new to delete)
  visibility = defined by you (whatever you assign the pointer to)

• stack variable
  visibility = from declaration until scope is exited
  lifetime = from declaration until declaring scope is exited

(1) more exactly: from initialization until deinitialization of the compilation unit (i.e. C / C++ file). Order of initialization of compilation units is not defined by the standard.

(2) Beware: if you instantiate a static variable in a header, each compilation unit gets its own copy.

You can use "break" to break the loop, which will not allow the loop to process more conditions

You should NOT use jQuery('selector').attr("tagName").toLowerCase(), because it only works in older versions of Jquery.

You could use $('selector').prop("tagName").toLowerCase() if you're certain that you're using a version of jQuery thats >= version 1.6.

Note :

You may think that EVERYONE is using jQuery 1.10+ or something by now (January 2016), but unfortunately that isn't really the case. For example, many people today are still using Drupal 7, and every official release of Drupal 7 to this day includes jQuery 1.4.4 by default.

So if do not know for certain if your project will be using jQuery 1.6+, consider using one of the options that work for ALL versions of jQuery :

Option 1 :

jQuery('selector')[0].tagName.toLowerCase()

Option 2

jQuery('selector')[0].nodeName.toLowerCase()

I wrote my own random number utility class just so that I would have something that functioned a bit more like Math.random() in Java. It has just two functions, and it's all made in C.

Header file:

//Random.h
void initRandomSeed(long firstSeed);
float nextRandomFloat();

Implementation file:

//Random.m
static unsigned long seed;

void initRandomSeed(long firstSeed)
{ 
    seed = firstSeed;
}

float nextRandomFloat()
{
    return (((seed= 1664525*seed + 1013904223)>>16) / (float)0x10000);
}

It's a pretty classic way of generating pseudo-randoms. In my app delegate I call:

#import "Random.h"

- (void)applicationDidFinishLaunching:(UIApplication *)application
{
    initRandomSeed( (long) [[NSDate date] timeIntervalSince1970] );
    //Do other initialization junk.
}

Then later I just say:

float myRandomNumber = nextRandomFloat() * 74;

Note that this method returns a random number between 0.0f (inclusive) and 1.0f (exclusive).

This is an easy way to add an underline, while maintaining other settings:

textView.setPaintFlags(textView.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

1. you have to have a reference to the form object in order to access its elements
2. the elements have to be declared public in order for another class to access them
3. don't do this - your class has to know too much about how your form is implemented; do not expose form controls outside of the form class
4. instead, make public properties on your form to get/set the values you are interested in
5. post more details of what you want and why, it sounds like you may be heading off in a direction that is not consistent with good encapsulation practices

Ahhhh, now it is clear. You seem to have problems binding back the value. Not with displaying it on the view. Indeed, that's the fault of the default model binder. You could write and use a custom one that will take into consideration the [DisplayFormat] attribute on your model. I have illustrated such a custom model binder here: https://stackoverflow.com/a/7836093/29407

Apparently some problems still persist. Here's my full setup working perfectly fine on both ASP.NET MVC 3 & 4 RC.

Model:

public class MyViewModel
{
    [DisplayName("date of birth")]
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
    public DateTime? Birth { get; set; }
}

Controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel
        {
            Birth = DateTime.Now
        });
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        return View(model);
    }
}

View:

@model MyViewModel

@using (Html.BeginForm())
{
    @Html.LabelFor(x => x.Birth)
    @Html.EditorFor(x => x.Birth)
    @Html.ValidationMessageFor(x => x.Birth)
    <button type="submit">OK</button>
}

Registration of the custom model binder in Application_Start:

ModelBinders.Binders.Add(typeof(DateTime?), new MyDateTimeModelBinder());

And the custom model binder itself:

public class MyDateTimeModelBinder : DefaultModelBinder
{
    public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
        var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);

        if (!string.IsNullOrEmpty(displayFormat) && value != null)
        {
            DateTime date;
            displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
            // use the format specified in the DisplayFormat attribute to parse the date
            if (DateTime.TryParseExact(value.AttemptedValue, displayFormat, CultureInfo.InvariantCulture, DateTimeStyles.None, out date))
            {
                return date;
            }
            else
            {
                bindingContext.ModelState.AddModelError(
                    bindingContext.ModelName,
                    string.Format("{0} is an invalid date format", value.AttemptedValue)
                );
            }
        }

        return base.BindModel(controllerContext, bindingContext);
    }
}

Now, no matter what culture you have setup in your web.config (<globalization> element) or the current thread culture, the custom model binder will use the DisplayFormat attribute's date format when parsing nullable dates.

The Alpha Remove section of the ImageMagick Usage Guide suggests using the -alpha remove option, e.g.:

convert in.png  -background white  -alpha remove  out.png

...using the -background color of your choosing.

The guide states:

This operation is simple and fast, and does the job without needing any extra memory use, or other side effects that may be associated with alternative transparency removal techniques. It is thus the prefered way of removing image transparency.

It additionally adds the note:

Note that while transparency is 'removed' the alpha channel will remain turned on, but will now be fully-opaque. If you no longer need the alpha channel you can then use Alpha Off to disable it.

Thus, if you do not need the alpha channel you can make your output image size smaller by adding the -alpha off option, e.g:

convert in.png  -background white  -alpha remove  -alpha off  out.png

There are more details on other, often-used techniques for removing transparency described in the Removing Transparency from Images section.

Included in that section is mention of an important caveat to the usage of -flatten as a technique for removing transparency:

However this will not work with "mogrify" or with a sequence of multiple images, basically because the "-flatten" operator is really designed to merge multiple images into a single image.

So, if you are converting several images at once, e.g. generating thumbnails from a PDF file, -flatten will not do what you want (it will flatten all images for all pages into one image). On the other hand, using the -alpha remove technique will still produce multiple images, each one having transparency removed.

Easy QR Code Library

A simple Android Easy QR Code Library. It is very easy to use, to use this library follow these steps.

For Gradle:

Step 1. Add it in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Step 2. Add the dependency:

dependencies {
        compile 'com.github.mrasif:easyqrlibrary:v1.0.0'
}

For Maven:

Step 1. Add the JitPack repository to your build file:

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

Step 2. Add the dependency:

<dependency>
    <groupId>com.github.mrasif</groupId>
    <artifactId>easyqrlibrary</artifactId>
    <version>v1.0.0</version>
</dependency>

For SBT:

Step 1. Add the JitPack repository to your build.sbt file:

resolvers += "jitpack" at "https://jitpack.io"

Step 2. Add the dependency:

libraryDependencies += "com.github.mrasif" % "easyqrlibrary" % "v1.0.0"

For Leiningen:

Step 1. Add it in your project.clj at the end of repositories:

:repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency:

:dependencies [[com.github.mrasif/easyqrlibrary "v1.0.0"]]

Add this in your layout xml file:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="20dp"
    tools:context=".MainActivity"
    android:orientation="vertical">

    <TextView
        android:id="@+id/tvData"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="No QR Data"/>
    <Button
        android:id="@+id/btnQRScan"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="QR Scan"/>

</LinearLayout>

Add this in your activity java files:

public class MainActivity extends AppCompatActivity implements View.OnClickListener{

    TextView tvData;
    Button btnQRScan;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tvData=findViewById(R.id.tvData);
        btnQRScan=findViewById(R.id.btnQRScan);

        btnQRScan.setOnClickListener(this);
    }

    @Override
    public void onClick(View view){
        switch (view.getId()){
            case R.id.btnQRScan: {
                Intent intent=new Intent(MainActivity.this, QRScanner.class);
                startActivityForResult(intent, EasyQR.QR_SCANNER_REQUEST);
            } break;
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        switch (requestCode){
            case EasyQR.QR_SCANNER_REQUEST: {
                if (resultCode==RESULT_OK){
                    tvData.setText(data.getStringExtra(EasyQR.DATA));
                }
            } break;
        }
    }
}

For customized scanner screen just add these lines when you start the scanner Activity.

Intent intent=new Intent(MainActivity.this, QRScanner.class);
intent.putExtra(EasyQR.IS_TOOLBAR_SHOW,true);
intent.putExtra(EasyQR.TOOLBAR_DRAWABLE_ID,R.drawable.ic_audiotrack_dark);
intent.putExtra(EasyQR.TOOLBAR_TEXT,"My QR");
intent.putExtra(EasyQR.TOOLBAR_BACKGROUND_COLOR,"#0588EE");
intent.putExtra(EasyQR.TOOLBAR_TEXT_COLOR,"#FFFFFF");
intent.putExtra(EasyQR.BACKGROUND_COLOR,"#000000");
intent.putExtra(EasyQR.CAMERA_MARGIN_LEFT,50);
intent.putExtra(EasyQR.CAMERA_MARGIN_TOP,50);
intent.putExtra(EasyQR.CAMERA_MARGIN_RIGHT,50);
intent.putExtra(EasyQR.CAMERA_MARGIN_BOTTOM,50);
startActivityForResult(intent, EasyQR.QR_SCANNER_REQUEST);

You are done. Ref. Link: https://mrasif.github.io/easyqrlibrary

First you want to change the file format from csv to txt. That is simple to do, just edit the file name and change csv to txt. (Windows will give you warning about possibly corrupting the data, but it is fine, just click ok). Then make a copy of the txt file so that now you have two files both with 2 millions rows of data. Then open up the first txt file and delete the second million rows and save the file. Then open the second txt file and delete the first million rows and save the file. Now change the two files back to csv the same way you changed them to txt originally.

The documentation (https://angular.io/guide/template-syntax#!#star-template) gives the following example. Say we have template code like this:

<hero-detail *ngIf="currentHero" [hero]="currentHero"></hero-detail>

Before it will be rendered, it will be "de-sugared". That is, the asterix notation will be transcribed to the notation:

<template [ngIf]="currentHero">
  <hero-detail [hero]="currentHero"></hero-detail>
</template>

If 'currentHero' is truthy this will be rendered as

<hero-detail> [...] </hero-detail>

But what if you want an conditional output like this:

<h1>Title</h1><br>
<p>text</p>

.. and you don't want the output be wrapped in a container.

You could write the de-sugared version directly like so:

<template [ngIf]="showContent">
  <h1>Title</h1>
  <p>text</p><br>
</template>

And this will work fine. However, now we need ngIf to have brackets [] instead of an asterix *, and this is confusing (https://github.com/angular/angular.io/issues/2303)

For that reason a different notation was created, like so:

<ng-container *ngIf="showContent"><br>
  <h1>Title</h1><br>
  <p>text</p><br>
</ng-container>

Both versions will produce the same results (only the h1 and p tag will be rendered). The second one is preferred because you can use *ngIf like always.

This will work too!

foreach($data as &$value) {
  $value['transaction_date'] = date('d/m/Y', $value['transaction_date']);
}

Yay for alternatives!

You are setting the extra with an array. You are then trying to get a single int.

Your code should be:

int[] arrayB = extras.getIntArray("numbers");

z-index property enables you to take your control at front. the bigger number you set the upper your element you get.

position property should be relative because position of html-element should be position relatively against other controls in all dimensions.

element.style {
   position:relative;
   z-index:1000; //change your number as per elements lies on your page.
}

Square brackets are meant for character class, and you're actually trying to match any one of: s, |, s (again), e, a, s (again), o and n.

Use parentheses instead for grouping:

(s|season)

or non-capturing group:

(?:s|season)

Note: Non-capture groups tell the engine that it doesn't need to store the match, while the other one (capturing group does). For small stuff, either works, for 'heavy duty' stuff, you might want to see first if you need the match or not. If you don't, better use the non-capture group to allocate more memory for calculation instead of storing something you will never need to use.

I would solve this problem simply by doing that:

numberText = {
    1: 'one', 2: 'two', 3: 'three', 4: 'four', 5: 'five',
    6: 'six', 7: 'seven', 8: 'eight', 9: 'nine', 10: 'ten',
    11: 'eleven', 12: 'twelve', 13: 'thirteen', 14: 'fourteen',
    15: 'fifteen', 16: 'sixteen', 17: 'seventeen', 18: 'eighteen',
    19: 'nineteen', 20: 'twenty',
    30: 'thirty', 40: 'forty', 50: 'fifty', 60: 'sixty',
    70: 'seventy', 80: 'eighty', 90: 'ninety',
    100: 'hundred', 1000: 'thousand', 1000000: 'million'
}


def numberToEnglishText(n):
    if n == 0:
        return 'zero'
    if n < 0:
        return 'negative ' + numberToEnglishText(-n)

    result = ''

    for num in sorted(numberText.keys(), reverse=True):
        count = int(n/num)

        if (count < 1):
            continue

        if (num >= 100):
            result += numberToEnglishText(count) + ' '

        result += numberText[num]
        n -= count * num
        if (n > 0):
            result += ' '

    return result

Travis R is correct. (I wish I could upvote ya.) I just got this working myself. With these routes:

resources :articles do
  resources :comments
end

You get paths like:

/articles/42
/articles/42/comments/99

routed to controllers at

app/controllers/articles_controller.rb
app/controllers/comments_controller.rb

just as it says at http://guides.rubyonrails.org/routing.html#nested-resources, with no special namespaces.

But partials and forms become tricky. Note the square brackets:

<%= form_for [@article, @comment] do |f| %>

Most important, if you want a URI, you may need something like this:

article_comment_path(@article, @comment)

Alternatively:

[@article, @comment]

as described at http://edgeguides.rubyonrails.org/routing.html#creating-paths-and-urls-from-objects

For example, inside a collections partial with comment_item supplied for iteration,

<%= link_to "delete", article_comment_path(@article, comment_item),
      :method => :delete, :confirm => "Really?" %>

What jamuraa says may work in the context of Article, but it did not work for me in various other ways.

There is a lot of discussion related to nested resources, e.g. http://weblog.jamisbuck.org/2007/2/5/nesting-resources

Interestingly, I just learned that most people's unit-tests are not actually testing all paths. When people follow jamisbuck's suggestion, they end up with two ways to get at nested resources. Their unit-tests will generally get/post to the simplest:

# POST /comments
post :create, :comment => {:article_id=>42, ...}

In order to test the route that they may prefer, they need to do it this way:

# POST /articles/42/comments
post :create, :article_id => 42, :comment => {...}

I learned this because my unit-tests started failing when I switched from this:

resources :comments
resources :articles do
  resources :comments
end

to this:

resources :comments, :only => [:destroy, :show, :edit, :update]
resources :articles do
  resources :comments, :only => [:create, :index, :new]
end

I guess it's ok to have duplicate routes, and to miss a few unit-tests. (Why test? Because even if the user never sees the duplicates, your forms may refer to them, either implicitly or via named routes.) Still, to minimize needless duplication, I recommend this:

resources :comments
resources :articles do
  resources :comments, :only => [:create, :index, :new]
end

Sorry for the long answer. Not many people are aware of the subtleties, I think.

I saw one example that uses Import/Export-CLIXML.

These are my favorite commands for the issue you're trying to resolve. And the simplest way to use them is.

$passwordPath = './password.txt'
if (-not (test-path $passwordPath)) {
    $cred = Get-Credential -Username domain\username -message 'Please login.'
    Export-CliXML -InputObject $cred -Path $passwordPath
}
$cred = Import-CliXML -path $passwordPath

So if the file doesn't locally exist it will prompt for the credentials and store them. This will take a [pscredential] object without issue and will hide the credentials as a secure string.

Finally just use the credential like you normally do.

Restart-Computer -ComputerName ... -Credentail $cred

Note on Securty:

Securely store credentials on disk

When reading the Solution, you might at first be wary of storing a password on disk. While it is natural (and prudent) to be cautious of littering your hard drive with sensitive information, the Export-CliXml cmdlet encrypts credential objects using the Windows standard Data Protection API. This ensures that only your user account can properly decrypt its contents. Similarly, the ConvertFrom-SecureString cmdlet also encrypts the password you provide.

Edit: Just reread the original question. The above will work so long as you've initialized the [pscredential] to the hard disk. That is if you drop that in your script and run the script once it will create that file and then running the script unattended will be simple.

You may consider using ex (which is a standard Unix command-based editor):

ex +g/match/d -cwq file

where:

• + executes given Ex command (man ex), same as -c which executes wq (write and quit)
• g/match/d - Ex command to delete lines with given match, see: Power of g

The above example is a POSIX-compliant method for in-place editing a file as per this post at Unix.SE and POSIX specifications for ex.

The difference with sed is that:

sed is a Stream EDitor, not a file editor.^BashFAQ

Unless you enjoy unportable code, I/O overhead and some other bad side effects. So basically some parameters (such as in-place/-i) are non-standard FreeBSD extensions and may not be available on other operating systems.

Yes, this is described in the documentation. You have to use the InOrder class.

Example (assuming two mocks already created):

InOrder inOrder = inOrder(serviceAMock, serviceBMock);

inOrder.verify(serviceAMock).methodOne();
inOrder.verify(serviceBMock).methodTwo();

Without using '%'.

public int lastDigit(int no){
    int n1 = no / 10;
    n1 = no - n1 * 10;
    return n1;
}

For those who use JUnit 5, Powermock is not an option. You'll require the following dependencies to successfully mock a static method with just Mockito.

testCompile    group: 'org.mockito', name: 'mockito-core',           version: '3.6.0'
testCompile    group: 'org.mockito', name: 'mockito-junit-jupiter',  version: '3.6.0'
testCompile    group: 'org.mockito', name: 'mockito-inline',         version: '3.6.0'

mockito-junit-jupiter add supports for JUnit 5.

And support for mocking static methods is provided by mockito-inline dependency.

Example:

@Test
void returnUtilTest() {
    assertEquals("foo", UtilClass.staticMethod("foo"));

    try (MockedStatic<UtilClass> classMock = mockStatic(UtilClass.class)) {

        classMock.when(() -> UtilClass.staticMethod("foo")).thenReturn("bar");

        assertEquals("bar", UtilClass.staticMethod("foo"));
     }

     assertEquals("foo", UtilClass.staticMethod("foo"));
}

The try-with-resource block is used to make the static mock remains temporary, so it's mocked only within that scope.

When not using a try block, make sure to close the scoped mock, once you are done with the assertions.

MockedStatic<UtilClass> classMock = mockStatic(UtilClass.class)
classMock.when(() -> UtilClass.staticMethod("foo")).thenReturn("bar");
assertEquals("bar", UtilClass.staticMethod("foo"));
classMock.close();

Mocking void methods:

When mockStatic is called on a class, all the static void methods in that class automatically get mocked to doNothing().

Calling m.check(side), meaning you are running actual code, but you can't run code outside main() - you can only define variables. In C++, code can only appear inside function bodies or in variable initializes.

If #uploadedfile is an input with type "file" :

var file = $("#uploadedfile")[0].files[0];
var fileName = file.name;
var fileSize = file.size;
alert("Uploading: "+fileName+" @ "+fileSize+"bytes");

Normally this would fire on the change event, like so:

$("#uploadedfile").on("change", function(){
   var file = this.files[0],
       fileName = file.name,
       fileSize = file.size;
   alert("Uploading: "+fileName+" @ "+fileSize+"bytes");
   CustomFileHandlingFunction(file);
});

FIDDLE

And it works, thanks @trichetriche. The problem was in my RequestOptions, apparently, you can not pass params or body to the RequestOptions while using the post. Removing one of them gives me an error, removing both and it works. Still no final solution to my problem, but I now have something to work with. Final working code.

public post(cmd: string, data: string): Observable<any> {

    const options = new RequestOptions({
      headers: this.getAuthorizedHeaders(),
      responseType: ResponseContentType.Json,
      withCredentials: false
    });

    console.log('Options: ' + JSON.stringify(options));

    return this.http.post(this.BASE_URL, JSON.stringify({
      cmd: cmd,
      data: data}), options)
      .map(this.handleData)
      .catch(this.handleError);
  }

I threw together a small test implementation of this. The basic idea is to call format and pass in the format string, and a map of objects, and the names that they have locally.

The output of the following is:

My dog is named fido, and Jane Doe owns him.

public class StringFormatter {

    private static final String fieldStart = "\\$\\{";
    private static final String fieldEnd = "\\}";

    private static final String regex = fieldStart + "([^}]+)" + fieldEnd;
    private static final Pattern pattern = Pattern.compile(regex);

    public static String format(String format, Map<String, Object> objects) {
        Matcher m = pattern.matcher(format);
        String result = format;
        while (m.find()) {
            String[] found = m.group(1).split("\\.");
            Object o = objects.get(found[0]);
            Field f = o.getClass().getField(found[1]);
            String newVal = f.get(o).toString();
            result = result.replaceFirst(regex, newVal);
        }
        return result;
    }

    static class Dog {
        public String name;
        public String owner;
        public String gender;
    }

    public static void main(String[] args) {
        Dog d = new Dog();
        d.name = "fido";
        d.owner = "Jane Doe";
        d.gender = "him";
        Map<String, Object> map = new HashMap<String, Object>();
        map.put("d", d);
        System.out.println(
           StringFormatter.format(
                "My dog is named ${d.name}, and ${d.owner} owns ${d.gender}.", 
                map));
    }
}

Note: This doesn't compile due to unhandled exceptions. But it makes the code much easier to read.

Also, I don't like that you have to construct the map yourself in the code, but I don't know how to get the names of the local variables programatically. The best way to do it, is to remember to put the object in the map as soon as you create it.

The following example produces the results that you want from your example:

public static void main(String[] args) {
    Map<String, Object> map = new HashMap<String, Object>();
    Site site = new Site();
    map.put("site", site);
    site.name = "StackOverflow.com";
    User user = new User();
    map.put("user", user);
    user.name = "jjnguy";
    System.out.println(
         format("Hello ${user.name},\n\tWelcome to ${site.name}. ", map));
}

_{I should also mention that I have no idea what Velocity is, so I hope this answer is relevant.}

IMPORTANT NOTE: You have to sort your data first.

The part I didn't get is that in the example construction

groups = []
uniquekeys = []
for k, g in groupby(data, keyfunc):
   groups.append(list(g))    # Store group iterator as a list
   uniquekeys.append(k)

k is the current grouping key, and g is an iterator that you can use to iterate over the group defined by that grouping key. In other words, the groupby iterator itself returns iterators.

Here's an example of that, using clearer variable names:

from itertools import groupby

things = [("animal", "bear"), ("animal", "duck"), ("plant", "cactus"), ("vehicle", "speed boat"), ("vehicle", "school bus")]

for key, group in groupby(things, lambda x: x[0]):
    for thing in group:
        print("A %s is a %s." % (thing[1], key))
    print("")
    

This will give you the output:

A bear is a animal.
A duck is a animal.

A cactus is a plant.

A speed boat is a vehicle.
A school bus is a vehicle.

In this example, things is a list of tuples where the first item in each tuple is the group the second item belongs to.

The groupby() function takes two arguments: (1) the data to group and (2) the function to group it with.

Here, lambda x: x[0] tells groupby() to use the first item in each tuple as the grouping key.

In the above for statement, groupby returns three (key, group iterator) pairs - once for each unique key. You can use the returned iterator to iterate over each individual item in that group.

Here's a slightly different example with the same data, using a list comprehension:

for key, group in groupby(things, lambda x: x[0]):
    listOfThings = " and ".join([thing[1] for thing in group])
    print(key + "s:  " + listOfThings + ".")

This will give you the output:

animals: bear and duck.
plants: cactus.
vehicles: speed boat and school bus.

While adding 'DirectoryIndex index.php' to a .htaccess file may work,

NOTE:

In general, you should never use .htaccess files

This is quoted from http://httpd.apache.org/docs/1.3/howto/htaccess.html
Although this refers to an older version of apache, I believe the principle still applies.

Adding the following to your httpd.conf (if you have access to it) is considered better form, causes less server overhead and has the exact same effect:

<Directory /myapp>
DirectoryIndex index.php
</Directory>

Please use SQL Server Data Tools from SQL Server Integration Services (Transfer Database Task) as here: https://stackoverflow.com/a/27777823/2127493

Richie's answer is close. It depends upon the language. Here is a good solution for java:

int smallest =  Integer.MAX_VALUE;
int array[]; // Assume it is filled.
int array_length = array.length;
for (int i = array_length - 1; i >= 0; i--) {
    if (array[i] < smallest) {
        smallest = array[i];
    }
}

I go through the array in reverse order, because comparing "i" to "array_length" in the loop comparison requires a fetch and a comparison (two operations), whereas comparing "i" to "0" is a single JVM bytecode operation. If the work being done in the loop is negligible, then the loop comparison consumes a sizable fraction of the time.

Of course, others pointed out that encapsulating the array and controlling inserts will help. If getting the minimum was ALL you needed, keeping the list in sorted order is not necessary. Just keep an instance variable that holds the smallest inserted so far, and compare it to each value as it is added to the array. (Of course, this fails if you remove elements. In that case, if you remove the current lowest value, you need to do a scan of the entire array to find the new lowest value.)

I am using Oracle Database and i had same problem. Eventually i found ORACLE DB is converting all the metadata (table/sp/view/trigger) in upper case.

And i was trying how i wrote table name (myTempTable) in sql whereas it expect how it store table name in databsae (MYTEMPTABLE). Also same applicable on column name.

It is quite common problem with developer whoever used sql and now jumped into ORACLE DB.

There are my config to support L and old versions of android:

apply plugin: 'com.android.application'

android {
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.example.uladzimir_klyshevich.myapplication"
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }


    productFlavors {
        l {
            minSdkVersion 'android-L'
            targetSdkVersion 'android-L'
            compileSdkVersion 'android-L'
        }
        old {
            minSdkVersion 10
            targetSdkVersion 20
            //TODO comment second line if build is not compiles for "L"
            compileSdkVersion 20
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    lCompile 'com.android.support:appcompat-v7:21.+'
    oldCompile 'com.android.support:appcompat-v7:19.1.0'
}

As result you will have flavors:

oldDebug
oldRelease
lDebug
lRelease

And can install your application on old versions of android.

document.getElementsByName("iframe_name")[0].contentWindow.document.body.focus();

very easy with android

int i=10000;
byte b1=(byte)Color.alpha(i);
byte b2=(byte)Color.red(i);
byte b3=(byte)Color.green(i);
byte b4=(byte)Color.blue(i);

You have to target screen size using media query for different screen size.

for iphone:

@media only screen 
    and (min-device-width : 375px) 
    and (max-device-width : 667px) 
    and (orientation : landscape) 
    and (-webkit-min-device-pixel-ratio : 2)
{ }

@media only screen 
    and (min-device-width : 375px) 
    and (max-device-width : 667px) 
    and (orientation : portrait) 
    and (-webkit-min-device-pixel-ratio : 2)
{ }

and for desktop version:

@media only screen (max-width: 1080){

}

First, you aren't actually creating 10 buttons. Second, you need to set the location of each button, or they will appear on top of each other. This will do the trick:

  for (int i = 0; i < 10; ++i)
  {
      var button = new Button();
      button.Location = new Point(button.Width * i + 4, 0);
      Controls.Add(button);
  }

Including the fb:app_id tag in your HTML HEAD will allow the Facebook scraper to associate the Open Graph entity for that URL with an application. This will allow any admins of that app to view Insights about that URL and any social plugins connected with it.

The fb:admins tag is similar, but allows you to just specify each user ID that you would like to give the permission to do the above.

You can include either of these tags or both, depending on how many people you want to admin the Insights, etc. A single as fb:admins is pretty much a minimum requirement. The rest of the Open Graph tags will still be picked up when people share and like your URL, however it may cause problems in the future, so please include one of the above.

fb:admins is specified like this:
<meta property="fb:admins" content="USER_ID"/>
OR
<meta property="fb:admins" content="USER_ID,USER_ID2,USER_ID3"/>

and fb:app_id like this:
<meta property="fb:app_id" content="APPID"/>

NullPointerException in some cases! Without criteria.setProjection(Projections.distinct(Projections.property("id"))) all query goes well! This solution is bad!

Another way is use SQLQuery. In my case following code works fine:

List result = getSession().createSQLQuery(
"SELECT distinct u.id as usrId, b.currentBillingAccountType as oldUser_type,"
+ " r.accountTypeWhenRegister as newUser_type, count(r.accountTypeWhenRegister) as numOfRegUsers"
+ " FROM recommendations r, users u, billing_accounts b WHERE "
+ " r.user_fk = u.id and"
+ " b.user_fk = u.id and"
+ " r.activated = true and"
+ " r.audit_CD > :monthAgo and"
+ " r.bonusExceeded is null and"
+ " group by u.id, r.accountTypeWhenRegister")
.addScalar("usrId", Hibernate.LONG)
.addScalar("oldUser_type", Hibernate.INTEGER)
.addScalar("newUser_type", Hibernate.INTEGER)
.addScalar("numOfRegUsers", Hibernate.BIG_INTEGER)
.setParameter("monthAgo", monthAgo)
.setMaxResults(20)
.list();

Distinction is done in data base! In opposite to:

criteria.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);

where distinction is done in memory, after load entities!

I'd use a button to trigger the input:

<button onclick="document.getElementById('fileUpload').click()">Open from File...</button>
<input type="file" id="fileUpload" name="files" style="display:none" />

Quick and clean.

The main benefit of "".equals(s) is you don't need the null check (equals will check its argument and return false if it's null), which you seem to not care about. If you're not worried about s being null (or are otherwise checking for it), I would definitely use s.isEmpty(); it shows exactly what you're checking, you care whether or not s is empty, not whether it equals the empty string

Nowadays there is a new(ish) API to do this directly. It works on modern browsers and on HTTPS (and localhost) only. Not supported by IE11.

IE11 has its own API.

And the workaround in the accepted answer can be used for unsecure hosts.

function copyToClipboard (text) {
  if (navigator.clipboard) { // default: modern asynchronous API
    return navigator.clipboard.writeText(text);
  } else if (window.clipboardData && window.clipboardData.setData) {     // for IE11
    window.clipboardData.setData('Text', text);
    return Promise.resolve();
  } else {
    // workaround: create dummy input
    const input = h('input', { type: 'text' });
    input.value = text;
    document.body.append(input);
    input.focus();
    input.select();
    document.execCommand('copy');
    input.remove();
    return Promise.resolve();
  }
}

Note: it uses Hyperscript to create the input element (but should be easy to adapt)

There is no need to make the input invisible, as it is added and removed so fast. Also when hidden (even using some clever method) some browsers will detect it and prevent the copy operation.

Instruction For Eclipse CDT 4.4 Luna and 4.5 Mars

First, before creating project, configure Eclipse syntax parser:

Window -> Preferences -> C/C++ -> Build -> Settings -> Discovery -> CDT GCC Build-in Compiler Settings

in the text box entitled Command to get compiler specs append -std=c++11

Now you can create project, configuration depends on what kind of project you created:

For project created as: File -> New -> Project -> C/C++ -> C++ Project

Right click on created project and open

Properties -> C/C++ Build -> Settings -> Tool Settings -> GCC C++ Compiler -> Dialect

Put -std=c++11 into text box entitled other dialect flags or select ISO C++11 from the Language standard drop down.

For CMake project

Generate eclipse project files (inside your project)

mkdir build
cd build
cmake -G"Eclipse CDT4 - Unix Makefiles" -D CMAKE_BUILD_TYPE=Debug ..

Then import generated directory to eclipse as standard eclipse project. Right click project and open

Properties -> C/C++ General -> Preprocessor Include Paths, Marcos etc. -> Providers

enable CDT GCC Build-in Compiler Settings and move it higher than Contributed PathEntry Containers (This is important)

Last Common Step

recompile, regenerate Project ->C/C++ Index and restart Eclipse.

Update for 2020 - BinaryPrimitives should now be preferred over BitConverter. It provides endian-specific APIs, and is less allocatey.

byte[] bytes = BitConverter.GetBytes(i);

although note also that you might want to check BitConverter.IsLittleEndian to see which way around that is going to appear!

Note that if you are doing this repeatedly you might want to avoid all those short-lived array allocations by writing it yourself via either shift operations (>> / <<), or by using unsafe code. Shift operations also have the advantage that they aren't affected by your platform's endianness; you always get the bytes in the order you expect them.

you can write a stored procedure like this:

CREATE PROCEDURE sanitize_TABLE()

BEGIN

#replace space with underscore

UPDATE Table SET FieldName = REPLACE(FieldName," ","_") WHERE FieldName is not NULL;

#delete dot

UPDATE Table SET FieldName = REPLACE(FieldName,".","") WHERE FieldName is not NULL;

#delete (

UPDATE Table SET FieldName = REPLACE(FieldName,"(","") WHERE FieldName is not NULL;

#delete )

UPDATE Table SET FieldName = REPLACE(FieldName,")","") WHERE FieldName is not NULL;

#raplace or delete any char you want

#..........................

END

In this way you have modularized control over table.

You can also generalize stored procedure making it, parametric with table to sanitoze input parameter

Set the tabindex of the canvas element to 1 or something like this

<canvas tabindex='1'></canvas>

It's an old trick to make any element focusable

Instead of "w" use "a" (append) mode with open function:

with open("games.txt", "a") as text_file:

For me,

1. I ended the process in Windows Task Manager: VsHub.exe.
2. Restarted Visual Studio.

After that, everything works like a charm again!

I found an easier way to do it and it works perfectly even if you don't know the path where the chrome is located.

First of all, you have to paste this code in the top of the module.

Option Explicit
Private pWebAddress As String
Public Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
(ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, _
ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

After that you have to create this two modules:

Sub LoadExplorer()
    LoadFile "Chrome.exe" ' Here you are executing the chrome. exe
End Sub

Sub LoadFile(FileName As String)
    ShellExecute 0, "Open", FileName, "http://test.123", "", 1 ' You can change the URL.
End Sub

With this you will be able (if you want) to set a variable for the url or just leave it like hardcode.

Ps: It works perfectly for others browsers just changing "Chrome.exe" to opera, bing, etc.

If you have defined a method inside your class as static, this is actually possible.

    class myClass
    {
    public:
        static void saySomething()
        {
            std::cout << "This is a static method!" << std::endl;
        }
    }; 

And from main, you declare a pointer and try to invoke the static method.

    myClass * pmyClass;
    pmyClass->saySomething();

/*    
Output:
This is a static method!
*/

This works fine because static methods do not belong to a specific instance of the class and they are not allocated as a part of any instance of the class.

Read more on static methods here: http://en.wikipedia.org/wiki/Static_method#Static_methods

There isn't one easy way to center div vertically which would do the trick in every situation.

However, there are lots of ways to do it depending on the situation.

Here are few of them:

• Set top and bottom padding of the parent element for example padding:20px 0px 20px 0px
• Use table, table cell centers its' content vertically
• Set parent element's position relative and the div's you want to vertically center to absolute and style it as top:50px; bottom:50px; for example

You may also google for "css vertical centering"

The regular expression for this is really simple. Just use a character class. The hyphen is a special character in character classes, so it needs to be first:

/[-!$%^&*()_+|~=`{}\[\]:";'<>?,.\/]/

You also need to escape the other regular expression metacharacters.

Edit: The hyphen is special because it can be used to represent a range of characters. This same character class can be simplified with ranges to this:

/[$-/:-?{-~!"^_`\[\]]/

There are three ranges. '$' to '/', ':' to '?', and '{' to '~'. the last string of characters can't be represented more simply with a range: !"^_`[].

Use an ACSII table to find ranges for character classes.

You could run jconsole (included with Java 6's SDK) then connect to your Java application. It will show you every Thread running and its stack trace.

myvariable=$(mysql -u user -p'password' -s -N <<QUERY_INPUT
    use databaseName;
    SELECT fieldName FROM tablename WHERE filedName='fieldValue';
QUERY_INPUT
)
echo "myvariable=$myvariable"

You could move the common parts to another configuration file and include from both server contexts. This should work:

server {
  listen 80;
  server_name server1.example;
  ...
  include /etc/nginx/include.d/your-common-stuff.conf;
}

server {
  listen 80;
  server_name another-one.example;
  ...
  include /etc/nginx/include.d/your-common-stuff.conf;
}

Edit: Here's an example that's actually copied from my running server. I configure my basic server settings in /etc/nginx/sites-enabled (normal stuff for nginx on Ubuntu/Debian). For example, my main server bunkus.org's configuration file is /etc/nginx/sites-enabled and it looks like this:

server {
  listen   80 default_server;
  listen   [2a01:4f8:120:3105::101:1]:80 default_server;

  include /etc/nginx/include.d/all-common;
  include /etc/nginx/include.d/bunkus.org-common;
  include /etc/nginx/include.d/bunkus.org-80;
}

server {
  listen   443 default_server;
  listen   [2a01:4f8:120:3105::101:1]:443 default_server;

  include /etc/nginx/include.d/all-common;
  include /etc/nginx/include.d/ssl-common;
  include /etc/nginx/include.d/bunkus.org-common;
  include /etc/nginx/include.d/bunkus.org-443;
}

As an example here's the /etc/nginx/include.d/all-common file that's included from both server contexts:

index index.html index.htm index.php .dirindex.php;
try_files $uri $uri/ =404;

location ~ /\.ht {
  deny all;
}

location = /favicon.ico {
  log_not_found off;
  access_log off;
}

location ~ /(README|ChangeLog)$ {
  types { }
  default_type text/plain;
}

I just ran into this question and, while it is old, I figured I'd add an answer for the archives. The OP asked about for loops, but their goal was to gather a random sample of rows from the table. For that task, Postgres 9.5+ offers the TABLESAMPLE clause on WHERE. Here's a good rundown:

https://www.2ndquadrant.com/en/blog/tablesample-in-postgresql-9-5-2/

I tend to use Bernoulli as it's row-based rather than page-based, but the original question is about a specific row count. For that, there's a built-in extension:

https://www.postgresql.org/docs/current/tsm-system-rows.html

CREATE EXTENSION tsm_system_rows;

Then you can grab whatever number of rows you want:

select * from playtime tablesample system_rows (15);

I've just come across this question too and found out that if anytime the build number gets corrupt because of any error-triggered hard shutdown of the jenkins instance you can set back the build number manually by just editing the file nextBuildNumber (pathToJenkins\jobs\jobxyz\nextBuildNumber) and then make a reload by using the option
Reload Configuration from Disk from the Manage Jenkins View.

store all your data initially

function PhoneListCtrl($scope, $http) {
  $http.get('phones/phones.json').success(function(data) {
    $scope.phones = data.splice(0, 5);
    $scope.allPhones = data;
  });

  $scope.orderProp = 'age';
  $scope.howMany = 5;
  //then here watch the howMany variable on the scope and update the phones array accordingly
  $scope.$watch("howMany", function(newValue, oldValue){
    $scope.phones = $scope.allPhones.splice(0,newValue)
  });
}

EDIT had accidentally put the watch outside the controller it should have been inside.

You can create mappings that work in insert mode. The way to do that is via inoremap. Note the 'i' at the beginning of the command (noremap is useful to avoid key map collisions). The corollary is 'n' for 'normal' mode. You can surmise what vim thinks is 'normal' ;)

HOWEVER, you really want to navigate around in text using 'normal' mode. Vim is super at this kind of thing and all that power is available from normal mode. Vim already provides easy ways to get from normal mode to insert mode (e.g., i, I, a, A, o, O). The trick is to make it easy to get into normal mode. The way to do that is to remap escape to a more convient key. But you need one that won't conflict with your regular typing. I use:

inoremap jj <Esc>

Since jj (that's 2 j's typed one after the other quickly) doesn't seem to appear in my vocabulary. Other's will remap to where it's comfortable.

The other essential change I make is to switch the CAPSLOCK and CONTROL keys on my keyboard (using the host computer's keyboard configuration) since I almost never use CAPSLOCK and it has that big, beautiful button right where I want it. (This is common for Emacs users. The downside is when you find yourself on an 'unfixed' keyboard! Aaarggh!)

Once you remap CAPSLOCK, you can comfortably use the following insert mode remappings:

Keeping in mind that some keys are already mapped in insert mode (backwards-kill-word is C-w (Control-w) by default, you might already have the bindings you want. That said, I prefer C-h so in my .vimrc I have:

inoremap <C-h> <C-w>

BUT, you probably want the same muscle memory spasm in normal mode, so I also map C-h as:

nnoremap <C-h> db

(d)elete (b)ackwards accomplishes the same thing with the same key chord. This kind of quick edit is one that I find useful in practice for typos. But stick to normal mode for moving around in text and anything more than killing the previous word. Once you get into the habit of changing modes (using a remap of course), it will be much more efficient than remapping insert mode.

If you want to even support for float values (Dot separated values) then you can use this expression :

var isNumber = /^\d+\.\d+$/.test(value);

I had huge difficulty getting this to work for a shell variable containing a filename with whitespace. For some reason using:

file="foo bar/baz"
scp [email protected]:"'$file'"

as in @Adrian's answer seems to fail.

Turns out that what works best is using a parameter expansion to prepend backslashes to the whitespace as follows:

file="foo bar/baz"
file=${file// /\\ }
scp [email protected]:"$file"

You can Enable DBMS_OUTPUT and set the buffer size. The buffer size can be between 1 and 1,000,000.

dbms_output.enable(buffer_size IN INTEGER DEFAULT 20000);
exec dbms_output.enable(1000000);

Check this

EDIT

As per the comment posted by Frank and Mat, you can also enable it with Null

exec dbms_output.enable(NULL);

buffer_size : Upper limit, in bytes, the amount of buffered information. Setting buffer_size to NULL specifies that there should be no limit. The maximum size is 1,000,000, and the minimum is 2,000 when the user specifies buffer_size (NOT NULL).

skip` didn't work, so my workaround is

$LinesCount = $(get-content $file).Count
get-content $file |
    select -Last $($LinesCount-1) | 
    set-content "$file-temp"
move "$file-temp" $file -Force

For your current structure, you could also try the following:

select cash.Country, cash.Value, cheque.Value, cash.Value + cheque.Value as [Total]
from Cash
join Cheque
on cash.Country = cheque.Country

I think I prefer a union between the two tables, and a group by on the country name as mentioned above.

But I would also recommend normalising your tables. Ideally you'd have a country table, with Id and Name, and a payments table with: CountryId (FK to countries), Total, Type (cash/cheque)

Example:

function Foo () { console.log('Foo function'); }_x000D_
var Bar = function () { console.log('Bar function'); };_x000D_
var Abc = function Xyz() { console.log('Abc function'); };_x000D_
_x000D_
var f = new Foo();_x000D_
var b = new Bar();_x000D_
var a = new Abc();_x000D_
_x000D_
console.log('f', f.constructor.name); // -> "Foo"_x000D_
console.log('b', b.constructor.name); // -> "Function"_x000D_
console.log('a', a.constructor.name); // -> "Xyz"

I know that my answer came late but it happens to me today and I solved it with the following approach:

^(([A-Z]+),)+([A-Z]+)$

So the first group (([A-Z]+),)+ will match all the repeated patterns except the final one ([A-Z]+) that will match the final one. and this will be dynamic no matter how many repeated groups in the string.

Use document.querySelector() if you want to avoid frameworks (which I almost always want to do).

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

Intent service is child of Service

IntentService: If you want to download a bunch of images at the start of opening your app. It's a one-time process and can clean itself up once everything is downloaded.

Service: A Service which will constantly be used to communicate between your app and back-end with web API calls. Even if it is finished with its current task, you still want it to be around a few minutes later, for more communication

In matplotlib grey colors can be given as a string of a numerical value between 0-1.
For example c = '0.1'

Then you can convert your third variable in a value inside this range and to use it to color your points.
In the following example I used the y position of the point as the value that determines the color:

from matplotlib import pyplot as plt

x = [1, 2, 3, 4, 5, 6, 7, 8, 9]
y = [125, 32, 54, 253, 67, 87, 233, 56, 67]

color = [str(item/255.) for item in y]

plt.scatter(x, y, s=500, c=color)

plt.show()

Yes you can do that by just creating a BroadcastReceiver that calls your Service when your Application boots. Here is a complete answer given by me.
Android - Start service on boot

If you don't want any icon/launcher for you Application you can do that also, just don't create any Activity with

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Just declare your Service as declared normally.

When you use jackson to map from string to your concrete class, especially if you work with generic type. then this issue may happen because of different class loader. i met it one time with below scenarior:

Project B depend on Library A

in Library A:

public class DocSearchResponse<T> {
 private T data;
}

it has service to query data from external source, and use jackson to convert to concrete class

public class ServiceA<T>{
  @Autowired
  private ObjectMapper mapper;
  @Autowired
  private ClientDocSearch searchClient;

  public DocSearchResponse<T> query(Criteria criteria){
      String resultInString = searchClient.search(criteria);
      return convertJson(resultInString)
  }
}

public DocSearchResponse<T> convertJson(String result){
     return mapper.readValue(result, new TypeReference<DocSearchResponse<T>>() {});
  }
}

in Project B:

public class Account{
 private String name;
 //come with other attributes
}

and i use ServiceA from library to make query and as well convert data

public class ServiceAImpl extends ServiceA<Account> {
    
}

and make use of that

public class MakingAccountService {
    @Autowired
    private ServiceA service;
    public void execute(Criteria criteria){
      
        DocSearchResponse<Account> result = service.query(criteria);
        Account acc = result.getData(); //  java.util.LinkedHashMap cannot be cast to com.testing.models.Account
    }
}

it happen because from classloader of LibraryA, jackson can not load Account class, then just override method convertJson in Project B to let jackson do its job

public class ServiceAImpl extends ServiceA<Account> {
        @Override
        public DocSearchResponse<T> convertJson(String result){
         return mapper.readValue(result, new TypeReference<DocSearchResponse<T>>() {});
      }
    }
 }

Check the permissions on your Ruby script (may not have execute permission), your theme file and directory (in case it can't read the theme or tries to create other themes in there), and the directory you're in when you run the script (in case it makes temporary files in the current directory rather then /tmp).

Any one of them could be causing you grief.

Also can be done from the environment variable:

export CURL_CA_BUNDLE=""

Use the following code

$("#modal").trigger('click');

Try that:

bool IsValidURL(string URL)
{
    string Pattern = @"^(?:http(s)?:\/\/)?[\w.-]+(?:\.[\w\.-]+)+[\w\-\._~:/?#[\]@!\$&'\(\)\*\+,;=.]+$";
    Regex Rgx = new Regex(Pattern, RegexOptions.Compiled | RegexOptions.IgnoreCase);
    return Rgx.IsMatch(URL);
}

It will accept URL like that:

• http(s)://www.example.com
• http(s)://stackoverflow.example.com
• http(s)://www.example.com/page
• http(s)://www.example.com/page?id=1&product=2
• http(s)://www.example.com/page#start
• http(s)://www.example.com:8080
• http(s)://127.0.0.1
• 127.0.0.1
• www.example.com
• example.com

The problem with your attempt at the psql command line is the direction of the slashes:

newTestDB-# /i E:\db-rbl-restore-20120511_Dump-20120514.sql   # incorrect
newTestDB-# \i E:/db-rbl-restore-20120511_Dump-20120514.sql   # correct

To be clear, psql commands start with a backslash, so you should have put \i instead. What happened as a result of your typo is that psql ignored everything until finding the first \, which happened to be followed by db, and \db happens to be the psql command for listing table spaces, hence why the output was a List of tablespaces. It was not a listing of "default tables of PostgreSQL" as you said.

Further, it seems that psql expects the filepath argument to delimit directories using the forward slash regardless of OS (thus on Windows this would be counter-intuitive).

It is worth noting that your attempt at "elevating permissions" had no relation to the outcome of the command you attempted to execute. Also, you did not say what caused the supposed "Permission Denied" error.

Finally, the extension on the dump file does not matter, in fact you don't even need an extension. Indeed, pgAdmin suggests a .backup extension when selecting a backup filename, but you can actually make it whatever you want, again, including having no extension at all. The problem is that pgAdmin seems to only allow a "Restore" of "Custom or tar" or "Directory" dumps (at least this is the case in the MAC OS X version of the app), so just use the psql \i command as shown above.

open windows powershell, run as administrater and SetExecution policy as Unrestricted then it will work.

The most likely place to find this sort of information is in the event viewer (under Administrative tools in XP or run eventvwr) This is where most services log warnings errors etc.

Here's a copy of a XML file to create a drawable with a white background, black border and rounded corners:

 <?xml version="1.0" encoding="UTF-8"?> 
    <shape xmlns:android="http://schemas.android.com/apk/res/android"> 
        <solid android:color="#ffffffff"/>    

        <stroke android:width="3dp"
                android:color="#ff000000"
                />

        <padding android:left="1dp"
                 android:top="1dp"
                 android:right="1dp"
                 android:bottom="1dp"
                 /> 

        <corners android:bottomRightRadius="7dp" android:bottomLeftRadius="7dp" 
         android:topLeftRadius="7dp" android:topRightRadius="7dp"/> 
    </shape>

save it as a xml file in the drawable directory, Use it like you would use any drawable background(icon or resource file) using its resource name (R.drawable.your_xml_name)
