I had the same issue. Rather than figure out the MVC code, I opted for a cheap hack that seems to work. In my Global.asax class:

member x.Application_EndRequest() =
  if x.Response.StatusCode = 401 then 
      let redir = "?redirectUrl=" + Uri.EscapeDataString x.Request.Url.PathAndQuery
      if x.Request.Url.LocalPath.ToLowerInvariant().Contains("admin") then
          x.Response.Redirect("/Login/Admin/" + redir)
      else
          x.Response.Redirect("/Login/Login/" + redir)

You can list all the files, in the aws s3 bucket using the command

aws s3 ls path/to/file

and to save it in a file, use

aws s3 ls path/to/file >> save_result.txt

if you want to append your result in a file otherwise:

aws s3 ls path/to/file > save_result.txt

if you want to clear what was written before.

It will work both in windows and Linux.

This can be done using the numeric_limits in C++:

http://www.cplusplus.com/reference/limits/numeric_limits/

These are the methods you probably want to look at:

infinity()  T   Representation of positive infinity, if available.
quiet_NaN() T   Representation of quiet (non-signaling) "Not-a-Number", if available.
signaling_NaN() T   Representation of signaling "Not-a-Number", if available.

For completeness, I would add that, if you wanted to copy an entire directory full of controlled AND uncontrolled files, you could use the following:

git mv old new
git checkout HEAD old

The uncontrolled files will be copied over, so you should clean them up:

git clean -fdx new

If you want all the bars to get the same color (fill), you can easily add it inside geom_bar.

ggplot(data=df, aes(x=c1+c2/2, y=c3)) + 
geom_bar(stat="identity", width=c2, fill = "#FF6666")

Add fill = the_name_of_your_var inside aes to change the colors depending of the variable :

c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2)

Use scale_fill_manual() if you want to manually the change of colors.

ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2) + 
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))

If you're already using Heroku, consider running your server via Foreman. It supports a .env file which is simply a list of lines with KEY=VAL that will be exported to your app before it runs.

In my case problem was when i added com.fasterxml.jackson.dataformat i put the version 2.11.0.

While all other Jackson dependencies were 2.8.0 and one of them was 2.11.0 and changing all to be 2.8.0 fixed it.

FYI, 2.11 is the latest but due to my legacy code, i kept it as 2.8 as well.

Ahhh, that's super simple, no programming required.

See: https://developers.facebook.com/docs/plugins/page-plugin

You'll want to keep the show stream option turned on. You can adjust width and heigth and a few other things.

Try this code:

import java.util.Scanner;

public class BasicElement {
    public static void main(String[] args){
        Scanner input = new Scanner(System.in);
        int hours;
        System.out.print("Enter the hours to convert:");
        hours =input.nextInt();
        int d=hours/24;
        int m=hours%24;
        System.out.println(d+"days"+" "+m+"hours");     

    }
}

If you are experiencing this problem when using Docker be sure to map the correct port numbers. If you map port 81:80 when running docker (or through docker-compose.yml), your nginx must listen on port 80 not 81, because docker does the mapping already.

I spent quite some time on this issue myself, so hope it can be to some help for future googlers.

If you are using mac, try giving root access to gradlew by doing

chmod +x ./gradlew

Try swapping the USB port the cable is plugged into.

Sounds crazy but after 20 minutes of debugging this worked for me.

if you are on ubuntu u can try these commands:

sudo apt install npm

npm install && npm run dev

Try this, to set the focus to the first input field:

$(this).parent().siblings('div.bottom').find("input.post").focus();

There is a library for this BarCode PHP. You just need to include a few files:

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

You can generate many types of barcodes, namely 1D or 2D. Add the required library:

require_once('class/BCGcode39.barcode.php');

Generate the colours:

// The arguments are R, G, and B for color.
$colorFront = new BCGColor(0, 0, 0);
$colorBack = new BCGColor(255, 255, 255);

After you have added all the codes, you will get this way:

Example

Since several have asked for an example here is what I was able to do to get it done

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

require_once('class/BCGcode128.barcode.php');

header('Content-Type: image/png');

$color_white = new BCGColor(255, 255, 255);

$code = new BCGcode128();
$code->parse('HELLO');

$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);

$drawing->draw();
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);

If you want to actually create the image file so you can save it then change

$drawing = new BCGDrawing('', $color_white);

to

$drawing = new BCGDrawing('image.png', $color_white);

You could use the ROLLUP operator

SELECT  CASE 
            WHEN (GROUPING([Type]) = 1) THEN 'Total'
            ELSE [Type] END AS [TYPE]
        ,SUM([Total Sales]) as Total_Sales
From    Before
GROUP BY
        [Type] WITH ROLLUP

There is a problem in that whilst:

LIKE 'WC[[]R]S123456' 

and:

LIKE 'WC\[R]S123456' ESCAPE '\'

Both work for SQL Server but neither work for Oracle.

It seems that there is no ISO/IEC 9075 way to recognize a pattern involving a left brace.

Assuming input[row][col],

    rows = len(input)
    cols = map(len, input)  #list of column lengths

Looks like people like doing spoonfeeding, so I have decided to post the worst solution to an easy task:

public static boolean isNumber(String s) throws Exception {
    boolean result = false;
    byte[] bytes = s.getBytes("ASCII");
    int tmp, i = bytes.length;
    while (i >0  && (result = ((tmp = bytes[--i] - '0') >= 0) && tmp <= 9));
    return result;
}

About the worst code I could imagine, but there might be other people here who can come up with even worse solutions.

Hm, containsNumber is worse:

public static boolean containsNumber(String s) throws Exception {
    boolean result = false;
    byte[] bytes = s.getBytes("ASCII");
    int tmp, i = bytes.length;
    while (i >0  && (true | (result |= ((tmp = bytes[--i] - '0') >= 0) && tmp <= 9)));
    return result;
}

This validates dd/mm/yyy dates. Edit your jquery.validate.js and add these.

Reference(Regex): Regex to validate date format dd/mm/yyyy

dateBR: function( value, element ) {
    return this.optional(element) || /^(?:(?:31(\/|-|\.)(?:0?[13578]|1[02]))\1|(?:(?:29|30)(\/|-|\.)(?:0?[1,3-9]|1[0-2])\2))(?:(?:1[6-9]|[2-9]\d)?\d{2})$|^(?:29(\/|-|\.)0?2\3(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00))))$|^(?:0?[1-9]|1\d|2[0-8])(\/|-|\.)(?:(?:0?[1-9])|(?:1[0-2]))\4(?:(?:1[6-9]|[2-9]\d)?\d{2})$/.test(value);
}

messages: {
    dateBR: "Invalid date."
}

classRuleSettings: {
    dateBR: {dateBR: true}
}

Usage:

$( "#myForm" ).validate({
    rules: {
        field: {
            dateBR: true
        }
    }
});

From the File menu, choose Project Structure (if you're running 0.4.4 there's a bug and the menu item doesn't have a title, but it still works), and choose the Android SDK item. You should see something like this where you can set up your JDK and SDK.

After setting it, quit Android Studio and relaunch it for good measure.

If you're uninstalling Anaconda to be able to use the base Python installation in the system, you could temporarily disable the path by following these steps and not uninstalling Anaconda.

Go to your home directory. Just a cd command will do.

Edit the file .bashrc.

Look for something like export PATH="/home/ubuntu/anaconda3/bin:$PATH" in the file.

Put a # at the beginning to comment it from the script.

#export PATH="/home/ubuntu/anaconda3/bin:$PATH"

Open a new terminal and you should be running the base python installation. This works on Linux systems. Should work on Mac too.

turns out it has to do with ng-Route and the order of loading script wrote a directive and put the API script on top of everything works.

if all your value are positive, you can do -max(-n)

 adb shell "mkdir -p /sdcard/tempDB" 
 adb shell "cp -r /data/data/[package.name]/databases/ /sdcard/tempDB/." 
 adb pull sdcard/tempDB/ . 
 adb shell "rm -r /sdcard/tempDB/*"

Haskell uses init to refer to all but the last element of a list (the inverse of tail, basically); would isInInit work, or is that too opaque?

easiest way to append class name using javascript. It can be useful when .siblings() are misbehaving.

For all the databases you have on the server:

mysql> SELECT SCHEMA_NAME 'database', default_character_set_name 'charset', DEFAULT_COLLATION_NAME 'collation' FROM information_schema.SCHEMATA;

Output:

| database                   | charset | collation          |
+----------------------------+---------+--------------------+
| information_schema         | utf8    | utf8_general_ci    |
| my_database                | latin1  | latin1_swedish_ci  |
...
+----------------------------+---------+--------------------+

For a single Database:

mysql> USE my_database;
mysql> show variables like "character_set_database";

Output:

    +----------------------------+---------+
    | Variable_name              |  Value  |

Getting the collation for Tables:

mysql> USE my_database;
mysql> SHOW TABLE STATUS WHERE NAME LIKE 'my_tablename';

OR - will output the complete SQL for create table:

I struggled with redirect not working for very long, none of what mentioned above was working for me, until I tried this:

Change:

return $this->redirect('site/secure');

to:

return $this->redirect(['site/secure']);

In other words, needed to enclose it within [] brackets! I am using PHP 7, might be the reason why?

I had this issue, the only problem was my Procfile was like this

web : node index.js

and I changed to

web:node index.js

the only problem was spaces

text-align: center will center it horizontally as for vertically put it in a span and give it a css of margin:auto 0; (you will probably also have to give the span a display: block property)

You can try this

var scroll=$('#scroll');
scroll.animate({scrollTop: scroll.prop("scrollHeight")});

use the JSON function >

JSON.parse(theString)

Block Elements: Elements liked div, p, headings are block level. They start from new line and occupy full width of parent element. Inline Elements: Elements liked b, i, span, img are inline level. They never start from new line and occupy width of content.

You can do this with dynamic objects:

var dynamicKeyValueArray = new[] { new {Key = "K1", Value = 10}, new {Key = "K2", Value = 5} };

foreach(var keyvalue in dynamicKeyValueArray)
{
    Console.Log(keyvalue.Key);
    Console.Log(keyvalue.Value);
}

I was trying to @Autowire a Spring-managed service into my Deserializer. Somebody tipped me off to Jackson using the new operator when invoking the serializers/deserializers. This meant no auto-wiring of Jackson's instance of my Deserializer. Here's how I was able to @Autowire my service class into my Deserializer:

context.xml

<mvc:annotation-driven>
  <mvc:message-converters>
    <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
      <property name="objectMapper" ref="objectMapper" />
    </bean>
  </mvc:message-converters>
</mvc>
<bean id="objectMapper" class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
    <!-- Add deserializers that require autowiring -->
    <property name="deserializersByType">
        <map key-type="java.lang.Class">
            <entry key="com.acme.Anchor">
                <bean class="com.acme.AnchorDeserializer" />
            </entry>
        </map>
    </property>
</bean>

Now that my Deserializer is a Spring-managed bean, auto-wiring works!

AnchorDeserializer.java

public class AnchorDeserializer extends JsonDeserializer<Anchor> {
    @Autowired
    private AnchorService anchorService;
    public Anchor deserialize(JsonParser parser, DeserializationContext context)
             throws IOException, JsonProcessingException {
        // Do stuff
    }
}

AnchorService.java

@Service
public class AnchorService {}

Update: While my original answer worked for me back when I wrote this, @xi.lin's response is exactly what is needed. Nice find!

This works!

import 'dart:async';
import 'dart:convert';

Future<http.Response> postRequest () async {
  var url ='https://pae.ipportalegre.pt/testes2/wsjson/api/app/ws-authenticate';

  Map data = {
    'apikey': '12345678901234567890'
  }
  //encode Map to JSON
  var body = json.encode(data);

  var response = await http.post(url,
      headers: {"Content-Type": "application/json"},
      body: body
  );
  print("${response.statusCode}");
  print("${response.body}");
  return response;
}

Short answer: Use the change event. Here's a couple of practical examples. Since I misread the question, I'll include jQuery examples along with plain JavaScript. You're not gaining much, if anything, by using jQuery though.

Single checkbox

Using querySelector.

var checkbox = document.querySelector("input[name=checkbox]");

checkbox.addEventListener('change', function() {
  if (this.checked) {
    console.log("Checkbox is checked..");
  } else {
    console.log("Checkbox is not checked..");
  }
});

<input type="checkbox" name="checkbox" />

Single checkbox with jQuery

$('input[name=checkbox]').change(function() {
  if ($(this).is(':checked')) {
    console.log("Checkbox is checked..")
  } else {
    console.log("Checkbox is not checked..")
  }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<input type="checkbox" name="checkbox" />

Multiple checkboxes

Here's an example of a list of checkboxes. To select multiple elements we use querySelectorAll instead of querySelector. Then use Array.filter and Array.map to extract checked values.

// Select all checkboxes with the name 'settings' using querySelectorAll.
var checkboxes = document.querySelectorAll("input[type=checkbox][name=settings]");
let enabledSettings = []

/*
For IE11 support, replace arrow functions with normal functions and
use a polyfill for Array.forEach:
https://vanillajstoolkit.com/polyfills/arrayforeach/
*/

// Use Array.forEach to add an event listener to each checkbox.
checkboxes.forEach(function(checkbox) {
  checkbox.addEventListener('change', function() {
    enabledSettings = 
      Array.from(checkboxes) // Convert checkboxes to an array to use filter and map.
      .filter(i => i.checked) // Use Array.filter to remove unchecked checkboxes.
      .map(i => i.value) // Use Array.map to extract only the checkbox values from the array of objects.
      
    console.log(enabledSettings)
  })
});

<label>
   <input type="checkbox" name="settings" value="forcefield">
   Enable forcefield
</label>
<label>
  <input type="checkbox" name="settings" value="invisibilitycloak">
  Enable invisibility cloak
</label>
<label>
  <input type="checkbox" name="settings" value="warpspeed">
  Enable warp speed
</label>

Multiple checkboxes with jQuery

let checkboxes = $("input[type=checkbox][name=settings]")
let enabledSettings = [];

// Attach a change event handler to the checkboxes.
checkboxes.change(function() {
  enabledSettings = checkboxes
    .filter(":checked") // Filter out unchecked boxes.
    .map(function() { // Extract values using jQuery map.
      return this.value;
    }) 
    .get() // Get array.
    
  console.log(enabledSettings);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<label>
   <input type="checkbox" name="settings" value="forcefield">
   Enable forcefield
</label>
<label>
  <input type="checkbox" name="settings" value="invisibilitycloak">
  Enable invisibility cloak
</label>
<label>
  <input type="checkbox" name="settings" value="warpspeed">
  Enable warp speed
</label>

Try the following

var original = 'www.test.com';
var stripped = original.substring(4);

In my case (Oracle), it's WHERE REGEXP_LIKE(column, 'regex.*'). See here:

SQL Function

Description

---

REGEXP_LIKE

This function searches a character column for a pattern. Use this function in the WHERE clause of a query to return rows matching the regular expression you specify.

...

REGEXP_REPLACE

This function searches for a pattern in a character column and replaces each occurrence of that pattern with the pattern you specify.

...

REGEXP_INSTR

This function searches a string for a given occurrence of a regular expression pattern. You specify which occurrence you want to find and the start position to search from. This function returns an integer indicating the position in the string where the match is found.

...

REGEXP_SUBSTR

This function returns the actual substring matching the regular expression pattern you specify.

(Of course, REGEXP_LIKE only matches queries containing the search string, so if you want a complete match, you'll have to use '^$' for a beginning (^) and end ($) match, e.g.: '^regex.*$'.)

as git says:

RHEL and derivatives typically ship older versions of git. You can download a tarball and build from source, or use a 3rd-party repository such as the IUS Community Project to obtain a more recent version of git.

there is good tutorial here. in my case (Centos7 server) after install had to logout and login again.

Very late, but it may help others:

end_date.mjd - start_date.mjd

https://apidock.com/ruby/Date/mjd

Just nib. Name the class Nib, with a capital N. For more on naming conventions and other style advice, see PEP 8, the Python style guide.

Guard your cast with instanceof

String myString;
if (object instanceof String) {
  myString = (String) object;
}

For this label:

<asp:label id="myLabel" runat="server" />

In the code behind use (C#):

myLabel.Text = "my text"; 

Update (following updated question):

You do not need to use FindControl - that whole line is superfluous:

  Label myLabel = this.FindControl("myLabel") as Label;
  myLabel.Text = "my text";

Should be just:

  myLabel.Text = "my text";

The Visual Studio designer should create a file with all the server side controls already added properly to the class (in a RankPage.aspx.designer.cs file, by default).

You are talking about a RankPage.cs file - the way Visual Studio would have named it is RankPage.aspx.cs. How are you linking these files together?

Old thread but I had the same problem now. If anyone encounters this he'll probably find this answer:

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(30, 30);
yourImageView.setLayoutParams(layoutParams);

This will work only if you add the ImageView as a subView to a LinearLayout. If you add it to a RelativeLayout you will need to call:

RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(30, 30);
yourImageView.setLayoutParams(layoutParams);

Three Possible Solutions

I know I'm coming late to the party, I've been looking if there were any new solutions to the variable configuration settings problem. There are a few answers that touch the solutions I have used in the past but most seem a bit convoluted. I thought I'd look at my old solutions and put the implementations together so that it might help people that are struggling with the same problem.

For this example I have used the following app setting in a console application:

<appSettings>
    <add key="EnvironmentVariableExample" value="%BaseDir%\bin"/>
    <add key="StaticClassExample" value="bin"/>
    <add key="InterpollationExample" value="{0}bin"/>
  </appSettings>

1. Use environment variables

I believe autocro autocro's answer touched on it. I'm just doing an implementation that should suffice when building or debugging without having to close visual studio. I have used this solution back in the day...

• Create a pre-build event that will use the MSBuild variables

  Warning: Use a variable that will not be replaced easily so use your project name or something similar as a variable name.

  SETX BaseDir "$(ProjectDir)"

• Reset variables; using something like the following:

  Refresh Environment Variables on Stack Overflow

• Use the setting in your code:

'

private void Test_Environment_Variables()
{
    string BaseDir = ConfigurationManager.AppSettings["EnvironmentVariableExample"];
    string ExpandedPath = Environment.ExpandEnvironmentVariables(BaseDir).Replace("\"", ""); //The function addes a " at the end of the variable
    Console.WriteLine($"From within the C# Console Application {ExpandedPath}");
}

'

2. Use string interpolation:

• Use the string.Format() function

`

private void Test_Interpollation()
{
    string ConfigPath = ConfigurationManager.AppSettings["InterpollationExample"];
    string SolutionPath = Path.GetFullPath(Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, @"..\..\"));
    string ExpandedPath = string.Format(ConfigPath, SolutionPath.ToString());
    Console.WriteLine($"Using old interpollation {ExpandedPath}");
}

`

3. Using a static class, This is the solution I mostly use.

• The implementation

`

private void Test_Static_Class()
{
    Console.WriteLine($"Using a static config class {Configuration.BinPath}");
}

`

• The static class

`

static class Configuration
{
    public static string BinPath
    {
        get
        {
            string ConfigPath = ConfigurationManager.AppSettings["StaticClassExample"];
            string SolutionPath = Path.GetFullPath(Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, @"..\..\"));
            return SolutionPath + ConfigPath;
        }
    }
}

`

Project Code:

App.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
    </startup>
  <appSettings>
    <add key="EnvironmentVariableExample" value="%BaseDir%\bin"/>
    <add key="StaticClassExample" value="bin"/>
    <add key="InterpollationExample" value="{0}bin"/>
  </appSettings>
</configuration>

Program.cs

using System;
using System.Configuration;
using System.IO;

namespace ConfigInterpollation
{
    class Program
    {
        static void Main(string[] args)
        {
            new Console_Tests().Run_Tests();
            Console.WriteLine("Press enter to exit");
            Console.ReadLine();
        }        
    }

    internal class Console_Tests
    {
        public void Run_Tests()
        {
            Test_Environment_Variables();
            Test_Interpollation();

A True or False version, based on @DMfll answer:

try:
    # python2
    from urlparse import urlparse
except:
    # python3
    from urllib.parse import urlparse

a = 'http://www.cwi.nl:80/%7Eguido/Python.html'
b = '/data/Python.html'
c = 532
d = u'dkakasdkjdjakdjadjfalskdjfalk'

def uri_validator(x):

print(uri_validator(a))
print(uri_validator(b))
print(uri_validator(c))
print(uri_validator(d))

Gives:

simply use the form_validation class of codeigniter:

strip_image_tags($str).

$this->load->library('form_validation');
$this->form_validation->set_rules('nombre_campo', 'label', 'strip_image_tags');

A variant using Bat/Powershell (need .net framework):

replace.bat :

@echo off

call:DoReplace "Findstr" "replacestr" test.txt test1.txt
exit /b

:DoReplace
echo ^(Get-Content "%3"^) ^| ForEach-Object { $_ -replace %1, %2 } ^| Set-Content %4>Rep.ps1
Powershell.exe -executionpolicy ByPass -File Rep.ps1
if exist Rep.ps1 del Rep.ps1
echo Done
pause

The problem is what happens when you get NumberFormatexception thrown? You print it and return nothing.

Note: You don't need to catch and throw an Exception back. Usually it is done to wrap it or print stack trace and ignore for example.

catch(RangeException e) {
     throw e;
}

There are two ways to disable ActionBar in Android.

requestWindowFeature(Window.FEATURE_NO_TITLE); 
setContentView(R.layout.activity_main); 

Classes are simply blueprints to create objects from. The constructor is some code that are run every time you create an object. Therefor it does'nt make sense to have two constructors. What happens is that the second over write the first.

What you typically use them for is create variables for that object like this:

>>> class testing:
...     def __init__(self, init_value):
...         self.some_value = init_value

So what you could do then is to create an object from this class like this:

>>> testobject = testing(5)

The testobject will then have an object called some_value that in this sample will be 5.

>>> testobject.some_value
5

But you don't need to set a value for each object like i did in my sample. You can also do like this:

>>> class testing:
...     def __init__(self):
...         self.some_value = 5

then the value of some_value will be 5 and you don't have to set it when you create the object.

>>> testobject = testing()
>>> testobject.some_value
5

the >>> and ... in my sample is not what you write. It's how it would look in pyshell...

You can change the tool used by git mergetool by passing git mergetool -t=<tool> or --tool=<tool>. To change the default (from vimdiff) use git config merge.tool <tool>.

Finding of week number for each date of a month (considering Monday as beginning of the week)

Keep the first date of month contant $B$13

=WEEKNUM(B18,2)-WEEKNUM($B$13,2)+1

WEEKNUM(B18,2) - returns the week number of the date mentioned in cell B18

WEEKNUM($B$13,2) - returns the week number of the 1st date of month in cell B13

Initialize k = j+1. You won't compare elements to themselves and you'll also not duplicate comparisons. For example, j = 0, k = 1 and k = 0, j = 1 compare the same set of elements. This would remove the k = 0, j = 1 comparison.

In the DOM, a tr element is (implicitly or explicitly) a child of tbody, thead, or tfoot, not a child of table (hence the 0 you got). So a general answer is:

var count = $('#gvPerformanceResult > * > tr').length;

This includes the rows of the table but excludes rows of any inner table.

The easiest way I've found is delete Android Studio from the applications folder, then download & install it again.

Using CPromise package we can use the following approach (Live demo)

import CPromise from "c-promise2";

const chain = new CPromise((resolve, reject, { onCancel }) => {
  const timer = setTimeout(resolve, 1000, 123);
  onCancel(() => clearTimeout(timer));
})
  .then((value) => value + 1)
  .then(
    (value) => console.log(`Done: ${value}`),
    (err, scope) => {
      console.warn(err); // CanceledError: canceled
      console.log(`isCanceled: ${scope.isCanceled}`); // true
    }
  );

setTimeout(() => {
  chain.cancel();
}, 100);

The same thing using AbortController (Live demo)

import CPromise from "c-promise2";

const controller= new CPromise.AbortController();

new CPromise((resolve, reject, { onCancel }) => {
  const timer = setTimeout(resolve, 1000, 123);
  onCancel(() => clearTimeout(timer));
})
  .then((value) => value + 1)
  .then(
    (value) => console.log(`Done: ${value}`),
    (err, scope) => {
      console.warn(err);
      console.log(`isCanceled: ${scope.isCanceled}`);
    }
  ).listen(controller.signal);

setTimeout(() => {
  controller.abort();
}, 100);

I find the syntax of the previous answers to be redundant and difficult to remember. Pandas introduced the query() method in v0.13 and I much prefer it. For your question, you could do df.query('col == val')

.env files are hidden by Netbeans. To show them do this:

Tools > Options > Miscellaneous > Files

Under Files Ignored be the IDE is Ignored Files Pattern:

The default is

^(CVS|SCCS|vssver.?\.scc|#.*#|%.*%|_svn)$|~$|^\.(?!(htaccess|git.+|hgignore)$).*$

Add env to the excluded-not-excluded bit

^(CVS|SCCS|vssver.?\.scc|#.*#|%.*%|_svn)$|~$|^\.(?!(env|htaccess|git.+|hgignore)$).*$

Files named .env now show.

Ignoring the smooth interpolation between points in your example graph (that would require doing some manual interpolation, or just have a higher resolution of your data), you can use pyplot.fill_between():

from matplotlib import pyplot as plt
import numpy as np

x = np.linspace(0, 30, 30)
y = np.sin(x/6*np.pi)
error = np.random.normal(0.1, 0.02, size=y.shape)
y += np.random.normal(0, 0.1, size=y.shape)

plt.plot(x, y, 'k-')
plt.fill_between(x, y-error, y+error)
plt.show()

See also the matplotlib examples.

use Python OS module to find csv file in a directory.

the simple example is here :

import os

# This is the path where you want to search
path = r'd:'

# this is the extension you want to detect
extension = '.csv'

for root, dirs_list, files_list in os.walk(path):
    for file_name in files_list:
        if os.path.splitext(file_name)[-1] == extension:
            file_name_path = os.path.join(root, file_name)
            print file_name
            print file_name_path   # This is the full path of the filter file

set - unordered collection of unique elements. List of elements can be passed to set's constructor. So, pass list with duplicate elements, we get set with unique elements and transform it back to list then get list with unique elements. I can say nothing about performance and memory overhead, but I hope, it's not so important with small lists.

list(set(my_not_unique_list))

Simply and short.

TL;DR, set the initial value

Using destructuring

arr.reduce( ( sum, { x } ) => sum + x , 0)

Without destructuring

arr.reduce( ( sum , cur ) => sum + cur.x , 0)

With Typescript

arr.reduce( ( sum, { x } : { x: number } ) => sum + x , 0)

Let's try the destructuring method:

const arr = [ { x: 1 }, { x: 2 }, { x: 4 } ]
const result = arr.reduce( ( sum, { x } ) => sum + x , 0)
console.log( result ) // 7

The key to this is setting initial value. The return value becomes first parameter of the next iteration.

Technique used in top answer is not idiomatic

The accepted answer proposes NOT passing the "optional" value. This is wrong, as the idiomatic way is that the second parameter always be included. Why? Three reasons:

1. Dangerous -- Not passing in the initial value is dangerous and can create side-effects and mutations if the callback function is careless.

Behold

const badCallback = (a,i) => Object.assign(a,i) 

const foo = [ { a: 1 }, { b: 2 }, { c: 3 } ]
const bar = foo.reduce( badCallback )  // bad use of Object.assign
// Look, we've tampered with the original array
foo //  [ { a: 1, b: 2, c: 3 }, { b: 2 }, { c: 3 } ]

If however we had done it this way, with the initial value:

const bar = foo.reduce( badCallback, {})
// foo is still OK
foo // { a: 1, b: 2, c: 3 }

For the record, unless you intend to mutate the original object, set the first parameter of Object.assign to an empty object. Like this: Object.assign({}, a, b, c).

2 - Better Type Inference --When using a tool like Typescript or an editor like VS Code, you get the benefit of telling the compiler the initial and it can catch errors if you're doing it wrong. If you don't set the initial value, in many situations it might not be able to guess and you could end up with creepy runtime errors.

3 - Respect the Functors -- JavaScript shines best when its inner functional child is unleashed. In the functional world, there is a standard on how you "fold" or reduce an array. When you fold or apply a catamorphism to the array, you take the values of that array to construct a new type. You need to communicate the resulting type--you should do this even if the final type is that of the values in the array, another array, or any other type.

Let's think about it another way. In JavaScript, functions can be pass around like data, this is how callbacks work, what is the result of the following code?

[1,2,3].reduce(callback)

Will it return an number? An object? This makes it clearer

[1,2,3].reduce(callback,0)

Read more on the functional programming spec here: https://github.com/fantasyland/fantasy-land#foldable

Some more background

The reduce method takes two parameters,

Array.prototype.reduce( callback, initialItem )

The callback function takes the following parameters

(accumulator, itemInArray, indexInArray, entireArray) => { /* do stuff */ }

For the first iteration,

• If initialItem is provided, the reduce function passes the initialItem as the accumulator and the first item of the array as the itemInArray.

• If initialItem is not provided, the reduce function passes the first item in the array as the initialItem and the second item in the array as itemInArray which can be confusing behavior.

I teach and recommend always setting the initial value of reduce.

You can check out the documentation at:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/Reduce

Hope this helps!

In my case, running on a Macbook, i had to turn off my firewall, thus allowing incoming connections from my android. RN v0.61.5

You had it nearly right in the last line. You want

str(bytes_string, 'utf-8')

because the type of bytes_string is bytes, the same as the type of b'abc'.

This can be confusing especially when you are not passing any argument to the method. So what gives?

When you call a method on a class (such as work() in this case), Python automatically passes self as the first argument.

Lets read that one more time: When you call a method on a class (such as work() in this case), Python automatically passes self as the first argument

So here Python is saying, hey I can see that work() takes 0 positional arguments (because you have nothing inside the parenthesis) but you know that the self argument is still being passed automatically when the method is called. So you better fix this and put that self keyword back in.

Adding self should resolve the problem. work(self)

class KeyStatisticCollection(DataDownloadUtilities.DataDownloadCollection):
def GenerateAddressStrings(self):
    pass    
def worker(self):
    pass
def DownloadProc(self):
    pass

Might sound silly but I simply called npm i node-fetch --save in the wrong project. Make sure you are in the correct directory.

This short little snippet will do it, but I can't see it working with a nested hash. I think it's pretty cute though

STRING.gsub(/[{}:]/,'').split(', ').map{|h| h1,h2 = h.split('=>'); {h1 => h2}}.reduce(:merge)

Steps 1. I eliminate the '{','}' and the ':' 2. I split upon the string wherever it finds a ',' 3. I split each of the substrings that were created with the split, whenever it finds a '=>'. Then, I create a hash with the two sides of the hash I just split apart. 4. I am left with an array of hashes which I then merge together.

EXAMPLE INPUT: "{:user_id=>11, :blog_id=>2, :comment_id=>1}" RESULT OUTPUT: {"user_id"=>"11", "blog_id"=>"2", "comment_id"=>"1"}

In the .service file under the [Unit] section:

[Unit]
Description=My Website
After=syslog.target network.target mongodb.service

The important part is the mongodb.service

The manpage describes it however due to formatting it's not as clear on first sight

systemd.unit - well formatted

systemd.unit - not so well formatted

Parameters are directly supported in MVC by simply adding parameters onto your action methods. Given an action like the following:

public ActionResult GetImages(string artistName, string apiKey)

MVC will auto-populate the parameters when given a URL like:

/Artist/GetImages/?artistName=cher&apiKey=XXX

One additional special case is parameters named "id". Any parameter named ID can be put into the path rather than the querystring, so something like:

public ActionResult GetImages(string id, string apiKey)

would be populated correctly with a URL like the following:

/Artist/GetImages/cher?apiKey=XXX

In addition, if you have more complicated scenarios, you can customize the routing rules that MVC uses to locate an action. Your global.asax file contains routing rules that can be customized. By default the rule looks like this:

routes.MapRoute(
            "Default",                                              // Route name
            "{controller}/{action}/{id}",                           // URL with parameters
            new { controller = "Home", action = "Index", id = "" }  // Parameter defaults
        );

If you wanted to support a url like

/Artist/GetImages/cher/api-key

you could add a route like:

routes.MapRoute(
            "ArtistImages",                                              // Route name
            "{controller}/{action}/{artistName}/{apikey}",                           // URL with parameters
            new { controller = "Home", action = "Index", artistName = "", apikey = "" }  // Parameter defaults
        );

and a method like the first example above.

SELECT CONVERT(DATETIME, CONVERT(CHAR(8), date, 112) + ' ' + CONVERT(CHAR(8), time, 108))
  FROM tablename

An elegant method would be to use the ~= compatible release operator according to PEP 440. In your case this would amount to:

package~=0.5.0

As an example, if the following versions exist, it would choose 0.5.9:

• 0.5.0
• 0.5.9
• 0.6.0

For clarification, each pair is equivalent:

~= 0.5.0
>= 0.5.0, == 0.5.*

~= 0.5
>= 0.5, == 0.*

Use backticks for system commands, which helps to store their results into Perl variables.

my $pid = 5892;
my $not = ``top -H -p $pid -n 1 | grep myprocess | wc -l`; 
print "not = $not\n";

Use this:

var $ =jQuery.noConflict();

You can use a property setter to raise an event whenever the value of a field is going to change.

You can have your own EventHandler delegate or you can use the famous System.EventHandler delegate.

Usually there's a pattern for this:

1. Define a public event with an event handler delegate (that has an argument of type EventArgs).
2. Define a protected virtual method called OnXXXXX (OnMyPropertyValueChanged for example). In this method you should check if the event handler delegate is null and if not you can call it (it means that there are one or more methods attached to the event delegation).
3. Call this protected method whenever you want to notify subscribers that something has changed.

Here's an example

private int _age;

//#1
public event System.EventHandler AgeChanged;

//#2
protected virtual void OnAgeChanged()
{ 
     if (AgeChanged != null) AgeChanged(this,EventArgs.Empty); 
}

public int Age
{
    get
    {
         return _age;
    }

    set
    {
         //#3
         _age=value;
         OnAgeChanged();
    }
 }

The advantage of this approach is that you let any other classes that want to inherit from your class to change the behavior if necessary.

If you want to catch an event in a different thread that it's being raised you must be careful not to change the state of objects that are defined in another thread which will cause a cross thread exception to be thrown. To avoid this you can either use an Invoke method on the object that you want to change its state to make sure that the change is happening in the same thread that the event has been raised or in case that you are dealing with a Windows Form you can use a BackgourndWorker to do things in a parallel thread nice and easy.

PHP-like passthru

import { spawn } from 'child_process';

export default async function passthru(exe, args, options) {
    return new Promise((resolve, reject) => {
        const env = Object.create(process.env);
        const child = spawn(exe, args, {
            ...options,
            env: {
                ...env,
                ...options.env,
            },
        });
        child.stdout.setEncoding('utf8');
        child.stderr.setEncoding('utf8');
        child.stdout.on('data', data => console.log(data));
        child.stderr.on('data', data => console.log(data));
        child.on('error', error => reject(error));
        child.on('close', exitCode => {
            console.log('Exit code:', exitCode);
            resolve(exitCode);
        });
    });
}

Usage

const exitCode = await passthru('ls', ['-al'], { cwd: '/var/www/html' })

you can use -f option to force delete the containers .

sudo docker rmi -f training/webapp

You may stop the containers using sudo docker stop training/webapp before deleting

It's been quite sometime since I asked this question. Now I understand it more clearly, I'm going to put a more complete answer to help others.

In Web API, it's very simple to remember how parameter binding is happening.

• if you POST simple types, Web API tries to bind it from the URL

• if you POST complex type, Web API tries to bind it from the body of the request (this uses a media-type formatter).

• If you want to bind a complex type from the URL, you'll use [FromUri] in your action parameter. The limitation of this is down to how long your data going to be and if it exceeds the url character limit.

  public IHttpActionResult Put([FromUri] ViewModel data) { ... }

• If you want to bind a simple type from the request body, you'll use [FromBody] in your action parameter.

  public IHttpActionResult Put([FromBody] string name) { ... }

as a side note, say you are making a PUT request (just a string) to update something. If you decide not to append it to the URL and pass as a complex type with just one property in the model, then the data parameter in jQuery ajax will look something like below. The object you pass to data parameter has only one property with empty property name.

var myName = 'ABC';
$.ajax({url:.., data: {'': myName}});

and your web api action will look something like below.

public IHttpActionResult Put([FromBody] string name){ ... }

Windows Solution

For Microsoft Windows Powershell:

git checkout master; git remote update origin --prune; git branch -vv | Select-String -Pattern ": gone]" | % { $_.toString().Trim().Split(" ")[0]} | % {git branch -d $_}

Explaination

git checkout master switches to the master branch

git remote update origin --prune prunes remote branches

git branch -vv gets a verbose output of all branches (git reference)

Select-String -Pattern ": gone]" gets only the records where they have been removed from remote.

% { $_.toString().Trim().Split(" ")[0]} get the branch name

% {git branch -d $_} deletes the branch

Don't use print ..., if you don't want spaces. Use string concatenation or formatting.

Concatenation:

print 'Value is "' + str(value) + '"'

Formatting:

print 'Value is "{}"'.format(value)

The latter is far more flexible, see the str.format() method documentation and the Formatting String Syntax section.

You'll also come across the older % formatting style:

print 'Value is "%d"' % value
print 'Value is "%d", but math.pi is %.2f' % (value, math.pi)

but this isn't as flexible as the newer str.format() method.

If you want to simply convert int 5 to char '5': (Only for integers 0 - 9)

int i = 5;
char c = (char) ('0' + i); // c is now '5';

Same problem happened to me. So if the service returns the response as a JSON string you have to deserialize the string first, then you will be able to deserialize the object type from it properly:

string json= string.Empty;
using (var streamReader = new StreamReader(response.GetResponseStream(), true))
        {
            json= new JavaScriptSerializer().Deserialize<string>(streamReader.ReadToEnd());

        }
//To deserialize to your object type...
MyType myType;
using (var memoryStream = new MemoryStream())
         {
            byte[] jsonBytes = Encoding.UTF8.GetBytes(@json);
            memoryStream.Write(jsonBytes, 0, jsonBytes.Length);
            memoryStream.Seek(0, SeekOrigin.Begin);
            using (var jsonReader = JsonReaderWriterFactory.CreateJsonReader(memoryStream, Encoding.UTF8,          XmlDictionaryReaderQuotas.Max, null))
            {
                var serializer = new DataContractJsonSerializer(typeof(MyType));
                myType = (MyType)serializer.ReadObject(jsonReader);

            }
        }

4 Sure it will work.... ;)

If you want all the chars of a word/sentence in a list, do this:

print(list("word"))
#  ['w', 'o', 'r', 'd']


print(list("some sentence"))
#  ['s', 'o', 'm', 'e', ' ', 's', 'e', 'n', 't', 'e', 'n', 'c', 'e']

Try sudo npm uninstall cordova -g to uninstall it globally and then just npm install cordova without the -g flag after cding to the local app directory

string foo = yourDateTime.ToUniversalTime()
                         .ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fff'Z'");

You don't need regex to split a string on whitespace:

In [1]: text = '''WYATT    - Ranked # 855 with    0.006   %
   ...: XAVIER   - Ranked # 587 with    0.013   %
   ...: YONG     - Ranked # 921 with    0.006   %
   ...: YOUNG    - Ranked # 807 with    0.007   %'''

In [2]: print '\n'.join(line.split()[0] for line in text.split('\n'))
WYATT
XAVIER
YONG
YOUNG

If you need to target multiple classes use:

#main_text .title, #main_text .title2 {
  /* Properties */
}

If there is no instance available then .class syntax is used to get the corresponding Class object for a class otherwise you can use getClass() method to get Class object. Since, there is no instance of primitive data type, we have to use .class syntax for primitive data types.

    package test;

    public class Test {
       public static void main(String[] args)
       {
          //there is no instance available for class Test, so use Test.class
          System.out.println("Test.class.getName() ::: " + Test.class.getName());

          // Now create an instance of class Test use getClass()
          Test testObj = new Test();
          System.out.println("testObj.getClass().getName() ::: " + testObj.getClass().getName());

          //For primitive type
          System.out.println("boolean.class.getName() ::: " + boolean.class.getName());
          System.out.println("int.class.getName() ::: " + int.class.getName());
          System.out.println("char.class.getName() ::: " + char.class.getName());
          System.out.println("long.class.getName() ::: " + long.class.getName());
       }
    }

The function Correlate of numpy works with 2 1D arrays that you want to correlate and returns one correlation value.

Using query comprehension syntax you could achieve the orderby as follows:

var uniqueColors = (from dbo in database.MainTable
                    where dbo.Property
                    orderby dbo.Color.Name ascending
                    select dbo.Color.Name).Distinct();

I have used below code in my SpringBoot application.

MimeMessage message = sender.createMimeMessage();
message.setContent(message, "text/html");
MimeMessageHelper helper = new MimeMessageHelper(message);

helper.setFrom(fromAddress);
helper.setTo(toAddress);
helper.setSubject(mailSubject);
helper.setText(mailText, true);

sender.send(message);

Below is a positive lookbehind JavaScript alternative showing how to capture the last name of people with 'Michael' as their first name.

1) Given this text:

const exampleText = "Michael, how are you? - Cool, how is John Williamns and Michael Jordan? I don't know but Michael Johnson is fine. Michael do you still score points with LeBron James, Michael Green Miller and Michael Wood?";

get an array of last names of people named Michael. The result should be: ["Jordan","Johnson","Green","Wood"]

2) Solution:

function getMichaelLastName2(text) {
  return text
    .match(/(?:Michael )([A-Z][a-z]+)/g)
    .map(person => person.slice(person.indexOf(' ')+1));
}

// or even
    .map(person => person.slice(8)); // since we know the length of "Michael "

3) Check solution

console.log(JSON.stringify(    getMichaelLastName(exampleText)    ));
// ["Jordan","Johnson","Green","Wood"]

Demo here: http://codepen.io/PiotrBerebecki/pen/GjwRoo

You can also try it out by running the snippet below.

const inputText = "Michael, how are you? - Cool, how is John Williamns and Michael Jordan? I don't know but Michael Johnson is fine. Michael do you still score points with LeBron James, Michael Green Miller and Michael Wood?";_x000D_
_x000D_
_x000D_
_x000D_
function getMichaelLastName(text) {_x000D_
  return text_x000D_
    .match(/(?:Michael )([A-Z][a-z]+)/g)_x000D_
    .map(person => person.slice(8));_x000D_
}_x000D_
_x000D_
console.log(JSON.stringify(    getMichaelLastName(inputText)    ));

Here a bit easier:

@echo off
set /p var=Are You Sure?[Y/N]: 
if %var%== Y goto ...
if not %var%== Y exit

or

@echo off
echo Are You Sure?[Y/N]
choice /c YN
if %errorlevel%==1 goto yes
if %errorlevel%==2 goto no
:yes
echo yes
goto :EOF
:no
echo no

I think the best way to do this is to use CheckedItems:

 foreach (DataRowView objDataRowView in CheckBoxList.CheckedItems)
 {
     // use objDataRowView as you wish                
 }

 
            string[] result = new string[table.Columns.Count];
            DataRow dr = table.Rows[0];
            for (int i = 0; i < dr.ItemArray.Length; i++)
            {
                result[i] = dr[i].ToString();
            }
            foreach (string str in result)
                Console.WriteLine(str);

You can use the string.Join method to do something like string.Join(",", o.Number, o.Id, o.whatever, ...).

edit: As digEmAll said, string.Join is faster than StringBuilder. They use an external implementation for the string.Join.

Profiling code (of course run in release without debug symbols):

class Program
{
    static void Main(string[] args)
    {
        Stopwatch sw = new Stopwatch();
        string r;
        int iter = 10000;

        string[] values = { "a", "b", "c", "d", "a little bit longer please", "one more time" };

        sw.Restart();
        for (int i = 0; i < iter; i++)
            r = Program.StringJoin(",", values);
        sw.Stop();
        Console.WriteLine("string.Join ({0} times): {1}ms", iter, sw.ElapsedMilliseconds);

        sw.Restart();
        for (int i = 0; i < iter; i++)
            r = Program.StringBuilderAppend(",", values);
        sw.Stop();
        Console.WriteLine("StringBuilder.Append ({0} times): {1}ms", iter, sw.ElapsedMilliseconds);
        Console.ReadLine();
    }

    static string StringJoin(string seperator, params string[] values)
    {
        return string.Join(seperator, values);
    }

    static string StringBuilderAppend(string seperator, params string[] values)
    {
        StringBuilder builder = new StringBuilder();
        builder.Append(values[0]);
        for (int i = 1; i < values.Length; i++)
        {
            builder.Append(seperator);
            builder.Append(values[i]);
        }
        return builder.ToString();
    }
}

string.Join took 2ms on my machine and StringBuilder.Append 5ms. So there is noteworthy difference. Thanks to digAmAll for the hint.

Try this one

$('<div></div>').appendTo('body')
  .html('<div><h6>Yes or No?</h6></div>')
  .dialog({
      modal: true, title: 'message', zIndex: 10000, autoOpen: true,
      width: 'auto', resizable: false,
      buttons: {
          Yes: function () {
              doFunctionForYes();
              $(this).dialog("close");
          },
          No: function () {
              doFunctionForNo();
              $(this).dialog("close");
          }
      },
      close: function (event, ui) {
          $(this).remove();
      }
});

Fiddle

The answer is no. Please see Spring Reference: Using @Transactional :

The @Transactional annotation may be placed before an interface definition, a method on an interface, a class definition, or a public method on a class

For methods which may fail, that is you specify boolean as return type, I would use the prefix try:

if (tryCreateFreshSnapshot())
{
  // ...
}

For all other cases use prefixes like is.. has.. was.. can.. allows.. ..

1. Remove "Network Link Conditioner", open "System Preferences", press CTRL and click the "Network Link Conditioner" icon. Select "Remove".
2. Restart your computer
3. Download the dmg "Hardware IO tools" for your XCode version from https://developer.apple.com/download/, you need to be logged in to do this.
4. Open it and install "Network Link Conditioner"
5. Restart your computer one last time.

You have to cast it to a correct format Playground.

yourTime := rand.Int31n(1000)
time.Sleep(time.Duration(yourTime) * time.Millisecond)

If you will check documentation for sleep, you see that it requires func Sleep(d Duration) duration as a parameter. Your rand.Int31n returns int32.

The line from the example works (time.Sleep(100 * time.Millisecond)) because the compiler is smart enough to understand that here your constant 100 means a duration. But if you pass a variable, you should cast it.

One way would be to enable telnet server on the machin you want to control services on (add/remove windows components)

Open dos prompt
Type telnet yourmachineip/name
Log on
type net start &serviceName* e.g. w3svc

This will start IIS or you can use net stop to stop a service.

Depending on your setup you need to look at a way of securing the telnet connection as I think its unencrypted.

This is the reason why mkv is such a good container, especially now that it's mature:

mkvmerge -o output.mkv video.mp4 subtitle.srt

I had the similar issue. I solved it the following way after a number of attempts to follow the pieces of advice in the forums. I am reposting the solution because it could be helpful for others.

I am running Windows 7 (Apache 2.2 & PHP 5.2.17 & MySQL 5.0.51a), the syntax in the file "httpd.conf" (C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\httpd.conf) was sensitive to slashes. You can check if "php.ini" is read from the right directory. Just type in your browser "localhost/index.php". The code of index.php is the following:

<?php echo phpinfo(); ?>

There is the row (not far from the top) called "Loaded Configuration File". So, if there is nothing added, then the problem could be that your "php.ini" is not read, even you uncommented (extension=php_mysql.dll and extension=php_mysqli.dll). So, in order to make it work I did the following step. I needed to change from

PHPIniDir 'c:\PHP\'

to

PHPIniDir 'c:\PHP'

Pay the attention that the last slash disturbed everything!

Now the row "Loaded Configuration File" gets "C:\PHP\php.ini" after refreshing "localhost/index.php" (before I restarted Apache2.2) as well as mysql block is there. MySQL and PHP are working together!

To handle undefined variables as well as nulls, you can use substitute with deparse:

nullSafe <- function(x) {
  if (!exists(deparse(substitute(x))) || is.null(x)) {
    return(NA)
  } else {
    return(x)
  }
}

nullSafe(my.nonexistent.var)

Try to update your compiler, I'm using GCC 4.7 on Windows 7 Starter x86 with MinGW and it compiles fine with the same options both in C99 and C11.

Code snippet to copy the clipboard:

Create a wrapper Python code in a module named (clipboard.py):

import clr
clr.AddReference('System.Windows.Forms')
from System.Windows.Forms import Clipboard
def setText(text):
    Clipboard.SetText(text)

def getText():
    return Clipboard.GetText()

Then import the above module into your code.

import io
import clipboard
code = clipboard.getText()
print code
code = "abcd"
clipboard.setText(code)

I must give credit to the blog post Clipboard Access in IronPython.

Old question but I usually use this solution:

import org.apache.commons.io.FilenameUtils;

String fileName = "/abc/defg/file.txt";

String basename = FilenameUtils.getBaseName(fileName);
String extension = FilenameUtils.getExtension(fileName);
System.out.println(basename); // file
System.out.println(extension); // txt (NOT ".txt" !)

You should be able to adjust the width using the .modal-dialog class selector (in conjunction with media queries or whatever strategy you're using for responsive design):

.modal-dialog {
    width: 400px;
}

The best would be to do this server-side or wrap the currency symbols in an element you can select before returning it to the browser, however if neither is an option, you can select all text nodes within the body and do the replace on them. Below i'm doing this using a plugin i wrote 2 years ago that was meant for highlighting text. What i'm doing is finding all occurrences of € and wrapping it in a span with the class currency-symbol, then i'm replacing the text of those spans.

Demo

(function($){

    $.fn.highlightText = function () {
        // handler first parameter
        // is the first parameter a regexp?
        var re,
            hClass,
            reStr,
            argType = $.type(arguments[0]),
            defaultTagName = $.fn.highlightText.defaultTagName;

        if ( argType === "regexp" ) {
            // first argument is a regular expression
            re = arguments[0];
        }       
        // is the first parameter an array?
        else if ( argType === "array" ) {
            // first argument is an array, generate
            // regular expression string for later use
            reStr = arguments[0].join("|");
        }       
        // is the first parameter a string?
        else if ( argType === "string" ) {
            // store string in regular expression string
            // for later use
            reStr = arguments[0];
        }       
        // else, return out and do nothing because this
        // argument is required.
        else {
            return;
        }

        // the second parameter is optional, however,
        // it must be a string or boolean value. If it is 
        // a string, it will be used as the highlight class.
        // If it is a boolean value and equal to true, it 
        // will be used as the third parameter and the highlight
        // class will default to "highlight". If it is undefined,
        // the highlight class will default to "highlight" and 
        // the third parameter will default to false, allowing
        // the plugin to match partial matches.
        // ** The exception is if the first parameter is a regular
        // expression, the third parameter will be ignored.
        argType = $.type(arguments[1]);
        if ( argType === "string" ) {
            hClass = arguments[1];
        }
        else if ( argType === "boolean" ) {
            hClass = "highlight";
            if ( reStr ) {
                reStr = "\\b" + reStr + "\\b";
            }
        }
        else {
            hClass = "highlight";
        }

        if ( arguments[2] && reStr ) {
            reStr = reStr = "\\b" + reStr + "\\b";
        } 

        // if re is not defined ( which means either an array or
        // string was passed as the first parameter ) create the
        // regular expression.
        if (!re) {
            re = new RegExp( "(" + reStr + ")", "ig" );
        }

        // iterate through each matched element
        return this.each( function() {
            // select all contents of this element
            $( this ).find( "*" ).andSelf().contents()

            // filter to only text nodes that aren't already highlighted
            .filter( function () {
                return this.nodeType === 3 && $( this ).closest( "." + hClass ).length === 0;
            })

            // loop through each text node
            .each( function () {
                var output;
                output = this.nodeValue
                    .replace( re, "<" + defaultTagName + " class='" + hClass + "'>$1</" + defaultTagName +">" );
                if ( output !== this.nodeValue ) {
                    $( this ).wrap( "<p></p>" ).parent()
                        .html( output ).contents().unwrap();
                }
            });
        });
    };

    $.fn.highlightText.defaultTagName = "span";

})( jQuery );

$("body").highlightText("€","currency-symbol");
$("span.currency-symbol").text("$");

volatile and transient keywords

1) transient keyword is used along with instance variables to exclude them from serialization process. If a field is transient its value will not be persisted.

On the other hand, volatile keyword is used to mark a Java variable as "being stored in main memory".

Every read of a volatile variable will be read from the computer's main memory, and not from the CPU cache, and that every write to a volatile variable will be written to main memory, and not just to the CPU cache.

2) transient keyword cannot be used along with static keyword but volatile can be used along with static.

3) transient variables are initialized with default value during de-serialization and there assignment or restoration of value has to be handled by application code.

For more information, see my blog:
http://javaexplorer03.blogspot.in/2015/07/difference-between-volatile-and.html

Simple solution:

<iframe onload="this.style.height=this.contentWindow.document.body.scrollHeight + 'px';" ...></iframe>

This works when the iframe and parent window are in the same domain. It does not work when the two are in different domains.

I have been successfull at impersonating users in another domain, but only with a trust set up between the 2 domains.

var token = IntPtr.Zero;
var result = LogonUser(userID, domain, password, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, ref token);
if (result)
{
    return WindowsIdentity.Impersonate(token);
}

I want to share an approach commented about and briefly discussed but show an actual example that I am currently using to help unit test EF-based services.

First, I would love to use the in-memory provider from EF Core, but this is about EF 6. Furthermore, for other storage systems like RavenDB, I'd also be a proponent of testing via the in-memory database provider. Again--this is specifically to help test EF-based code without a lot of ceremony.

Here are the goals I had when coming up with a pattern:

• It must be simple for other developers on the team to understand
• It must isolate the EF code at the barest possible level
• It must not involve creating weird multi-responsibility interfaces (such as a "generic" or "typical" repository pattern)
• It must be easy to configure and setup in a unit test

I agree with previous statements that EF is still an implementation detail and it's okay to feel like you need to abstract it in order to do a "pure" unit test. I also agree that ideally, I would want to ensure the EF code itself works--but this involves a sandbox database, in-memory provider, etc. My approach solves both problems--you can safely unit test EF-dependent code and create integration tests to test your EF code specifically.

The way I achieved this was through simply encapsulating EF code into dedicated Query and Command classes. The idea is simple: just wrap any EF code in a class and depend on an interface in the classes that would've originally used it. The main issue I needed to solve was to avoid adding numerous dependencies to classes and setting up a lot of code in my tests.

This is where a useful, simple library comes in: Mediatr. It allows for simple in-process messaging and it does it by decoupling "requests" from the handlers that implement the code. This has an added benefit of decoupling the "what" from the "how". For example, by encapsulating the EF code into small chunks it allows you to replace the implementations with another provider or totally different mechanism, because all you are doing is sending a request to perform an action.

Utilizing dependency injection (with or without a framework--your preference), we can easily mock the mediator and control the request/response mechanisms to enable unit testing EF code.

First, let's say we have a service that has business logic we need to test:

public class FeatureService {

  private readonly IMediator _mediator;

  public FeatureService(IMediator mediator) {
    _mediator = mediator;
  }

  public async Task ComplexBusinessLogic() {
    // retrieve relevant objects

    var results = await _mediator.Send(new GetRelevantDbObjectsQuery());
    // normally, this would have looked like...
    // var results = _myDbContext.DbObjects.Where(x => foo).ToList();

    // perform business logic
    // ...    
  }
}

Do you start to see the benefit of this approach? Not only are you explicitly encapsulating all EF-related code into descriptive classes, you are allowing extensibility by removing the implementation concern of "how" this request is handled--this class doesn't care if the relevant objects come from EF, MongoDB, or a text file.

Now for the request and handler, via MediatR:

public class GetRelevantDbObjectsQuery : IRequest<DbObject[]> {
  // no input needed for this particular request,
  // but you would simply add plain properties here if needed
}

public class GetRelevantDbObjectsEFQueryHandler : IRequestHandler<GetRelevantDbObjectsQuery, DbObject[]> {
  private readonly IDbContext _db;

  public GetRelevantDbObjectsEFQueryHandler(IDbContext db) {
    _db = db;
  }

  public DbObject[] Handle(GetRelevantDbObjectsQuery message) {
    return _db.DbObjects.Where(foo => bar).ToList();
  }
}

As you can see, the abstraction is simple and encapsulated. It's also absolutely testable because in an integration test, you could test this class individually--there are no business concerns mixed in here.

So what does a unit test of our feature service look like? It's way simple. In this case, I'm using Moq to do mocking (use whatever makes you happy):

[TestClass]
public class FeatureServiceTests {

  // mock of Mediator to handle request/responses
  private Mock<IMediator> _mediator;

  // subject under test
  private FeatureService _sut;

  [TestInitialize]
  public void Setup() {

    // set up Mediator mock
    _mediator = new Mock<IMediator>(MockBehavior.Strict);

    // inject mock as dependency
    _sut = new FeatureService(_mediator.Object);
  }

  [TestCleanup]

    _mediator.Setup(x => x.Send(It.IsAny<GetRelevantDbObjectsQuery>(), default(CancellationToken)).ReturnsAsync(dbObjects.ToArray()).Callback(
    (GetRelevantDbObjectsQuery message, CancellationToken token) => {
       // using Moq Callback functionality, you can make assertions
       // on expected request being passed in
       Assert.IsNotNull(message);
    });

    // act
    _sut.ComplexBusinessLogic();

    // assertions
  }

}

You can see all we need is a single setup and we don't even need to configure anything extra--it's a very simple unit test. Let's be clear: This is totally possible to do without something like Mediatr (you would simply implement an interface and mock it for tests, e.g. IGetRelevantDbObjectsQuery), but in practice for a large codebase with many features and queries/commands, I love the encapsulation and innate DI support Mediatr offers.

If you're wondering how I organize these classes, it's pretty simple:

- MyProject
  - Features
    - MyFeature
      - Queries
      - Commands
      - Services
      - DependencyConfig.cs (Ninject feature modules)

Organizing by feature slices is beside the point, but this keeps all relevant/dependent code together and easily discoverable. Most importantly, I separate the Queries vs. Commands--following the Command/Query Separation principle.

This meets all my criteria: it's low-ceremony, it's easy to understand, and there are extra hidden benefits. For example, how do you handle saving changes? Now you can simplify your Db Context by using a role interface (IUnitOfWork.SaveChangesAsync()) and mock calls to the single role interface or you could encapsulate committing/rolling back inside your RequestHandlers--however you prefer to do it is up to you, as long as it's maintainable. For example, I was tempted to create a single generic request/handler where you'd just pass an EF object and it would save/update/remove it--but you have to ask what your intention is and remember that if you wanted to swap out the handler with another storage provider/implementation, you should probably create explicit commands/queries that represent what you intend to do. More often than not, a single service or feature will need something specific--don't create generic stuff before you have a need for it.

There are of course caveats to this pattern--you can go too far with a simple pub/sub mechanism. I've limited my implementation to only abstracting EF-related code, but adventurous developers could start using MediatR to go overboard and message-ize everything--something good code review practices and peer reviews should catch. That's a process issue, not an issue with MediatR, so just be cognizant of how you're using this pattern.

You wanted a concrete example of how people are unit testing/mocking EF and this is an approach that's working successfully for us on our project--and the team is super happy with how easy it is to adopt. I hope this helps! As with all things in programming, there are multiple approaches and it all depends on what you want to achieve. I value simplicity, ease of use, maintainability, and discoverability--and this solution meets all those demands.

For install with zsh and Homebrew:

brew install nvm

Then Add the following to ~/.zshrc or your desired shell configuration file:

export NVM_DIR="$HOME/.nvm"
. "/usr/local/opt/nvm/nvm.sh"

Then install a node version and use it.

nvm install 7.10.1
nvm use 7.10.1

One way to handle this is to create a new BufferedImage, and tell it's graphics object to draw your scaled image into the new BufferedImage:

final float FACTOR  = 4f;
BufferedImage img = ImageIO.read(new File("graphic.png"));
int scaleX = (int) (img.getWidth() * FACTOR);
int scaleY = (int) (img.getHeight() * FACTOR);
Image image = img.getScaledInstance(scaleX, scaleY, Image.SCALE_SMOOTH);
BufferedImage buffered = new BufferedImage(scaleX, scaleY, TYPE);
buffered.getGraphics().drawImage(image, 0, 0 , null);

That should do the trick without casting.

In python, A dynamic array is an 'array' from the array module. E.g.

from array import array
x = array('d')          #'d' denotes an array of type double
x.append(1.1)
x.append(2.2)
x.pop()                 # returns 2.2

This datatype is essentially a cross between the built-in 'list' type and the numpy 'ndarray' type. Like an ndarray, elements in arrays are C types, specified at initialization. They are not pointers to python objects; this may help avoid some misuse and semantic errors, and modestly improves performance.

However, this datatype has essentially the same methods as a python list, barring a few string & file conversion methods. It lacks all the extra numerical functionality of an ndarray.

See https://docs.python.org/2/library/array.html for details.

Too late, just in case some one is looking for another way:

void Main()
{
    string jsonString = @"{
  'Stores': [
    'Lambton Quay',
    'Willis Street'
  ],
  'Manufacturers': [
    {
      'Name': 'Acme Co',
      'Products': [
        {
          'Name': 'Anvil',
          'Price': 50
        }
      ]
    },
    {
      'Name': 'Contoso',
      'Products': [
        {
          'Name': 'Elbow Grease',
          'Price': 99.95
        },
        {
          'Name': 'Headlight Fluid',
          'Price': 4
        }
      ]
    }
  ]
}";

    Product product = new Product();
    //Serializing to Object
    Product obj = JObject.Parse(jsonString).SelectToken("$.Manufacturers[?(@.Name == 'Acme Co' && @.Name != 'Contoso')]").ToObject<Product>();

    Console.WriteLine(obj);
}


public class Product
{
    public string Name { get; set; }
    public decimal Price { get; set; }
}

you can use Vuex to handle all your global data

Python is very picky about white space and indentation, more so than many languages. The reason is, rather than using curly braces and semi colons (like javascript or php) python looks for a return character (press enter/return on your keyboard) instead of the semicolon, and a colon with a tab after it for a opening curly brace. When the next piece of code is unindented, it expects that this is the same as a closing curly brace in Javascript or PHP.

From ==>https://teamtreehouse.com/community/what-is-a-indentationerror-expected-an-indented-block

Immediately after you start a new activity, using startActivity, make sure you call finish() so that the current activity is not stacked behind the new one.

EDIT With regards to your comment:

What you're suggesting is not particularly how the android app flow usually works, and how the users expect it to work. What you can do if you really want to, is to make sure that every startActivity leading up to that activity, is a startActivityForResult and has an onActivityResult listener that checks for an exit code, and bubbles that back. You can read more about that here. Basically, use setResult before finishing an activity, to set an exit code of your choice, and if your parent activity receives that exit code, you set it in that activity, and finish that one, etc...

I came upon this post looking to do the same and came up with my own solution I wanted to offer for future visitors of this page (and to see if doing this way presents any problems I had not forseen).

If you want to get a simple true or false output and want to do this with one line of code without a function or a loop you could serialize the array and then use stripos to search for the value:

stripos(serialize($my_array),$needle)

It seems to work for me.

In addition to the above, I would like to point out that client-side validation (HTML code, javascript, etc.) is never enough. Also check the length server-side, or just don't check at all (if it's not so important that people can be allowed to get around it, then it's not important enough to really warrant any steps to prevent that, either).

Also, fellows, he (or she) said HTML, not XHTML. ;)

If you're okay with a shallow copy, the underscore.js library has a clone method.

y = _.clone(x);

or you can extend it like

copiedObject = _.extend({},originalObject);

My favorite way in Chrome is clicking on a bookmarklet:

javascript:(function(){function read(url){var r=new XMLHttpRequest();r.open('HEAD',url,false);r.send(null);return r.getAllResponseHeaders();}alert(read(window.location))})();

Put this code in your developer console pad.

Don't forget if you already have a DateTime object and are not sure if it's UTC or Local, it's easy enough to use the methods on the object directly:

DateTime convertedDate = DateTime.Parse(date);
DateTime localDate = convertedDate.ToLocalTime();

How do we adjust for the extra hour?

Unless specified .net will use the local pc settings. I'd have a read of: http://msdn.microsoft.com/en-us/library/system.globalization.daylighttime.aspx

By the looks the code might look something like:

DaylightTime daylight = TimeZone.CurrentTimeZone.GetDaylightChanges( year );

And as mentioned above double check what timezone setting your server is on. There are articles on the net for how to safely affect the changes in IIS.

However, I disagree the official definition of Guide to naming conventions on groupId, artifactId, and version which proposes the groupId must start with a reversed domain name you control.

com means this project belongs to a company, and org means this project belongs to a social organization. These are alright, but for those strange domain like xxx.tv, xxx.uk, xxx.cn, it does not make sense to name the groupId started with "tv.","cn.", the groupId should deliver the basic information of the project rather than the domain.

Whilst more of a workaround, if you're running an Intel Mac, you could go the virtualisation route - at least then you can run the same tools.

If you can catch this in time and you don't have the ability to ROLLBACK or use the transaction log, you can take a backup immediately and use a tool like Redgate's SQL Data Compare to generate a script to "restore" the affected data. This worked like a charm for me. :)

Or, written in one line:

std::cout << std::distance(sampleArray.begin(),std::max_element(sampleArray.begin(), sampleArray.end()));

Have you ever tried to do this? :p

var str = '3.8';ie
alert( +(str) + 0.2 );

+(string) will cast string into float.

Handy!

So in order to solve your problem, you can do something like this:

var floatValue = +(str.replace(/,/,'.'));

To a kill a specific port in Linux use below command

sudo fuser -k Port_Number/tcp

replace Port_Number with your occupied port.

This also could be easiest way to add items in ListBox.

for (int i = 0; i < MyList.Count; i++)
{
        listBox1.Items.Add(MyList.ElementAt(i));
}

Further improvisation of this code can add items at runtime.

Just as a addition. You can find the Catalina Paths in

In the VM Arguments the Paths are listed and changeable

From similar question DB2 - find and compare the lentgh of the value in a table field - add RTRIM since LENGTH will return length of column definition. This should be correct:

select * from table where length(RTRIM(fieldName))=10

UPDATE 27.5.2019: maybe on older db2 versions the LENGTH function returned the length of column definition. On db2 10.5 I have tried the function and it returns data length, not column definition length:

select fieldname
, length(fieldName) len_only
, length(RTRIM(fieldName)) len_rtrim
from (values (cast('1234567890  ' as varchar(30)) )) 
as tab(fieldName)

FIELDNAME                      LEN_ONLY    LEN_RTRIM
------------------------------ ----------- -----------
1234567890                              12          10

One can test this by using this term:

where length(fieldName)!=length(rtrim(fieldName))

No, JavaScript can not directly connect to MySQL. But you can mix JS with PHP to do so.

JavaScript is a client-side language and your MySQL database is going to be running on a server

$.ajax({
        url: 'http://url.of.my.server/submit',
        dataType: "jsonp",
        jsonp: 'callback',
        jsonpCallback: 'jsonp_callback'
    });

jsonp is the querystring parameter name that is defined to be acceptable by the server while the jsonpCallback is the javascript function name to be executed at the client.
When you use such url:

url: 'http://url.of.my.server/submit?callback=?'

the question mark ? at the end instructs jQuery to generate a random function while the predfined behavior of the autogenerated function will just invoke the callback -the sucess function in this case- passing the json data as a parameter.

$.ajax({
        url: 'http://url.of.my.server/submit?callback=?',
        success: function (data, status) {
            mySurvey.closePopup();
        },
        error: function (xOptions, textStatus) {
            mySurvey.closePopup();
        }
    });

The same goes here if you are using $.getJSON with ? placeholder it will generate a random function while the predfined behavior of the autogenerated function will just invoke the callback:

$.getJSON('http://url.of.my.server/submit?callback=?',function(data){
//process data here
});

Why don't you just save/serve the CSS file as UTF-8?

nav a:hover:after {
    content: "?";
}

If that's not good enough, and you want to keep it all-ASCII:

nav a:hover:after {
    content: "\2193";
}

The general format for a Unicode character inside a string is \000000 to \FFFFFF – a backslash followed by six hexadecimal digits. You can leave out leading 0 digits when the Unicode character is the last character in the string or when you add a space after the Unicode character. See the spec below for full details.

Relevant part of the CSS2 spec:

Third, backslash escapes allow authors to refer to characters they cannot easily put in a document. In this case, the backslash is followed by at most six hexadecimal digits (0..9A..F), which stand for the ISO 10646 ([ISO10646]) character with that number, which must not be zero. (It is undefined in CSS 2.1 what happens if a style sheet does contain a character with Unicode codepoint zero.) If a character in the range [0-9a-fA-F] follows the hexadecimal number, the end of the number needs to be made clear. There are two ways to do that:

1. with a space (or other white space character): "\26 B" ("&B"). In this case, user agents should treat a "CR/LF" pair (U+000D/U+000A) as a single white space character.
2. by providing exactly 6 hexadecimal digits: "\000026B" ("&B")

In fact, these two methods may be combined. Only one white space character is ignored after a hexadecimal escape. Note that this means that a "real" space after the escape sequence must be doubled.

If the number is outside the range allowed by Unicode (e.g., "\110000" is above the maximum 10FFFF allowed in current Unicode), the UA may replace the escape with the "replacement character" (U+FFFD). If the character is to be displayed, the UA should show a visible symbol, such as a "missing character" glyph (cf. 15.2, point 5).

• Note: Backslash escapes are always considered to be part of an identifier or a string (i.e., "\7B" is not punctuation, even though "{" is, and "\32" is allowed at the start of a class name, even though "2" is not).
  The identifier "te\st" is exactly the same identifier as "test".

Comprehensive list: Unicode Character 'DOWNWARDS ARROW' (U+2193).

Use the ToDictionary method directly.

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

This is probably the simplest way of doing it:

sed -r 's/\s+//g' filename > output
mv ouput filename

Steps that you should follow if you want the thread dump of your StandAlone Java Process

Step 1: Get the Process ID for the shell script calling the java program

linux$ ps -aef | grep "runABCD"

user1  **8535**  4369   0   Mar 25 ?           0:00 /bin/csh /home/user1/runABCD.sh

user1 17796 17372   0 08:15:41 pts/49      0:00 grep runABCD

Step 2: Get the Process ID for the Child which was Invoked by the runABCD. Use the above PID to get the childs.

linux$ ps -aef | grep **8535**

user1  **8536**  8535   0   Mar 25 ?         126:38 /apps/java/jdk/sun4/SunOS5/1.6.0_16/bin/java -cp /home/user1/XYZServer

user1  8535  4369   0   Mar 25 ?           0:00 /bin/csh /home/user1/runABCD.sh

user1 17977 17372   0 08:15:49 pts/49      0:00 grep 8535

Step 3: Get the JSTACK for the particular process. Get the Process id of your XYSServer process. i.e. 8536

linux$ jstack **8536** > threadDump.log

You can use tree to generate something very similar to your example. Once you have the output, you can wrap it in a <pre> tag to preserve the plain text formatting.

You have to workaround this via static application context accessor approach:

@Component
public class StaticContextAccessor {

    private static StaticContextAccessor instance;

    @Autowired
    private ApplicationContext applicationContext;

    @PostConstruct
    public void registerInstance() {
        instance = this;
    }

    public static <T> T getBean(Class<T> clazz) {
        return instance.applicationContext.getBean(clazz);
    }

}

Then you can access bean instances in a static manner.

public class Boo {

    public static void randomMethod() {
         StaticContextAccessor.getBean(Foo.class).doStuff();
    }

}

An update

Turns out now brew cask install sublime-text installs the most up to date version (e.g. 3) by default and brew cask is now part of the standard brew-installation.

I would suppose that you can use a variable in the result, but aside from getting the ORDER BY piece in a view, you will not see a benefit by implicitly stating "TOP 100 PERCENT":

declare @t int
set @t=100
select top (@t) percent * from tableOf

In some cases you may want the Rails root without having to load Rails.

For example, you get a quicker feedback cycle when TDD'ing models that do not depend on Rails by requiring spec_helper instead of rails_helper.

# spec/spec_helper.rb

require 'pathname'

rails_root = Pathname.new('..').expand_path(File.dirname(__FILE__))

[
  rails_root.join('app', 'models'),
  # Add your decorators, services, etc.
].each do |path|
  $LOAD_PATH.unshift path.to_s
end

Which allows you to easily load Plain Old Ruby Objects from their spec files.

# spec/models/poro_spec.rb

require 'spec_helper'

require 'poro'

RSpec.describe ...

Much easier – this is what I use to avoid Shortlink tracking – is the following:

…which also follows links.

sed is the Stream EDitor. It can do a whole pile of really cool things, but the most common is text replacement.

The s,%,$,g part of the command line is the sed command to execute. The s stands for substitute, the , characters are delimiters (other characters can be used; /, : and @ are popular). The % is the pattern to match (here a literal percent sign) and the $ is the second pattern to match (here a literal dollar sign). The g at the end means to globally replace on each line (otherwise it would only update the first match).

create or replace procedure my_proc(  v_number IN number,p_rc OUT SYS_REFCURSOR )
as
begin
open p_rc
for select 1 col1
     from dual;
 end;
 /

and then write a function lie this which calls your stored procedure

 create or replace function my_proc_test(v_number IN NUMBER) RETURN sys_refcursor
 as
 p_rc sys_refcursor;
 begin
 my_proc(v_number,p_rc);
 return p_rc;
 end
 /

then you can run this SQL query in the SQLDeveloper editor.

 SELECT my_proc_test(3) FROM DUAL;

you will see the result in the console right click on it and cilck on single record view and edit the result you can see the all the records that were returned by the ref cursor.

Take a look at OPENROWSET, and do something like:

SELECT * INTO #TEMPTABLE FROM OPENROWSET('SQLNCLI'
     , 'Server=(local)\SQL2008;Trusted_Connection=yes;',
     'SELECT * FROM ' + @tableName)

In your controller, render the new action from your create action if validation fails, with an instance variable, @car populated from the user input (i.e., the params hash). Then, in your view, add a logic check (either an if block around the form or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car is set.

For Xcode 7, you have a much simpler solution. The only extra work is that you have to create a configuration plist file for exporting archive.

(Compared to Xcode 6, in the results of xcrun xcodebuild -help, -exportFormat and -exportProvisioningProfile options are not mentioned any more; the former is deleted, and the latter is superseded by -exportOptionsPlist.)

Step 1, change directory to the folder including .xcodeproject or .xcworkspace file.

cd MyProjectFolder

Step 2, use Xcode or /usr/libexec/PlistBuddy exportOptions.plist to create export options plist file. By the way, xcrun xcodebuild -help will tell you what keys you have to insert to the plist file.

Step 3, create .xcarchive file (folder, in fact) as follows(build/ directory will be automatically created by Xcode right now),

xcrun xcodebuild -scheme MyApp -configuration Release archive -archivePath build/MyApp.xcarchive

Step 4, export as .ipa file like this, which differs from Xcode6

xcrun xcodebuild -exportArchive -exportPath build/ -archivePath build/MyApp.xcarchive/ -exportOptionsPlist exportOptions.plist

Now, you get an ipa file in build/ directory. Just send it to apple App Store.

By the way, the ipa file created by Xcode 7 is much larger than by Xcode 6.

This grants root access with the same password from any machine in *.example.com:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%.example.com' 
    IDENTIFIED BY 'some_characters' 
    WITH GRANT OPTION;
FLUSH PRIVILEGES;

If name resolution is not going to work, you may also grant access by IP or subnet:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.%'
    IDENTIFIED BY 'some_characters'  
    WITH GRANT OPTION;
FLUSH PRIVILEGES;

If you want to retrive a particular value from an XML file

 XmlDocument _LocalInfo_Xml = new XmlDocument();
            _LocalInfo_Xml.Load(fileName);
            XmlElement _XmlElement;
            _XmlElement = _LocalInfo_Xml.GetElementsByTagName("UserId")[0] as XmlElement;
            string Value = _XmlElement.InnerText;

A slightly more concise example that builds on top of the other answers here. I leveraged the code generation that is shipped with Visual Studio to remove most of the extra invocation code and replaced it with typed objects instead.

Ok here is my version of doing this. I noticed that you want your output to be 7, which means you dont want to count special characters and numbers. So here is regex pattern:

re.findall("[a-zA-Z_]+", string)

Where [a-zA-Z_] means it will match any character beetwen a-z (lowercase) and A-Z (upper case).

About spaces. If you want to remove all extra spaces, just do:

string = string.rstrip().lstrip() # Remove all extra spaces at the start and at the end of the string
while "  " in string: # While  there are 2 spaces beetwen words in our string...
    string = string.replace("  ", " ") # ... replace them by one space!

put this line in your windows form (on load or better in a public method like "binddata" ):

//
// bind the data and make the grid sortable 
//
this.datagridview1.MakeSortable( myenumerablecollection ); 

Put this code in a file called DataGridViewExtensions.cs (or similar)

// MakeSortable extension. 
// this will make any enumerable collection sortable on a datagrid view.  

//
// BEGIN MAKESORTABLE - Mark A. Lloyd
//
// Enables sort on all cols of a DatagridView 

//

Try this Simple Steps....

NOTE: Please check device location latitude & logitude if you are using simulator means. By defaults its none only.

Step 1: Import CoreLocation framework in .h File

#import <CoreLocation/CoreLocation.h>

Step 2: Add delegate CLLocationManagerDelegate

@interface yourViewController : UIViewController<CLLocationManagerDelegate>
{
    CLLocationManager *locationManager;
    CLLocation *currentLocation;
}

Step 3: Add this code in class file

- (void)viewDidLoad
{
    [super viewDidLoad];
    [self CurrentLocationIdentifier]; // call this method
}

Step 4: Method to detect current location

//------------ Current Location Address-----
-(void)CurrentLocationIdentifier
{
    //---- For getting current gps location
    locationManager = [CLLocationManager new];
    locationManager.delegate = self;
    locationManager.distanceFilter = kCLDistanceFilterNone;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    [locationManager startUpdatingLocation];
    //------
}

Step 5: Get location using this method

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
    currentLocation = [locations objectAtIndex:0];
    [locationManager stopUpdatingLocation];
    CLGeocoder *geocoder = [[CLGeocoder alloc] init] ;
    [geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *placemarks, NSError *error)
     {
         if (!(error))
         {
             CLPlacemark *placemark = [placemarks objectAtIndex:0];
             NSLog(@"\nCurrent Location Detected\n");
             NSLog(@"placemark %@",placemark);
             NSString *locatedAt = [[placemark.addressDictionary valueForKey:@"FormattedAddressLines"] componentsJoinedByString:@", "];
             NSString *Address = [[NSString alloc]initWithString:locatedAt];
             NSString *Area = [[NSString alloc]initWithString:placemark.locality];
             NSString *Country = [[NSString alloc]initWithString:placemark.country];
             NSString *CountryArea = [NSString stringWithFormat:@"%@, %@", Area,Country];
             NSLog(@"%@",CountryArea);
         }
         else
         {
             NSLog(@"Geocode failed with error %@", error);
             NSLog(@"\nCurrent Location Not Detected\n");
             //return;
             CountryArea = NULL;
         }
         /*---- For more results 
         placemark.region);
         placemark.country);
         placemark.locality); 
         placemark.name);
         placemark.ocean);
         placemark.postalCode);
         placemark.subLocality);
         placemark.location);
          ------*/
     }];
}

is there a possibility that casting a double created via Math.round() will still result in a truncated down number

No, round() will always round your double to the correct value, and then, it will be cast to an long which will truncate any decimal places. But after rounding, there will not be any fractional parts remaining.

Here are the docs from Math.round(double):

Returns the closest long to the argument. The result is rounded to an integer by adding 1/2, taking the floor of the result, and casting the result to type long. In other words, the result is equal to the value of the expression:

(long)Math.floor(a + 0.5d)

You can also use backtrace Ruby gem (I'm the author):

require 'backtrace'
begin
  # do something dangerous
rescue StandardError => e
  puts Backtrace.new(e)
end

I was using CyanogenMod 12.1 and was building with libgdx when I met with the same error. Rebuilding didn't work for me. My phone was connected as UMS or USB mass storage to my PC when I ran the app. Just changed the USB configuration from mass storage to MTP and it fixed my problem.

This can be logically solved using a property. Here I have a property called a key.

1. Take out any String property in the object and put it in the list.
2. Check in the list weather that property contains if so then remove it.
3. Return the object list.

List<Object> objectList = new ArrayList<>();
 List<String> keyList = new ArrayList<>();
  objectList.forEach( obj -> {
   if(keyList.contains(unAvailabilityModel.getKey())) 
         objectList.remove(unAvailabilityModel); 
    else
        keyList.add(unAvailabilityModel.getKey();
});
return objectList;

This will ensure you get a two-digit day and month.

function formattedDate(d = new Date) {
  let month = String(d.getMonth() + 1);
  let day = String(d.getDate());
  const year = String(d.getFullYear());

  if (month.length < 2) month = '0' + month;
  if (day.length < 2) day = '0' + day;

  return `${day}/${month}/${year}`;
}

Or terser:

function formattedDate(d = new Date) {
  return [d.getDate(), d.getMonth()+1, d.getFullYear()]
      .map(n => n < 10 ? `0${n}` : `${n}`).join('/');
}

My problem was something like that:

FileStream ms = new FileStream(path, FileMode.Open, FileAccess.ReadWrite);

but instead of using path I should use File.FullName... I don't know if it's going to help anyone else, just passing my own experience with this erro given!

Well... I flipped the internet upside down three times but did not find anything that might help me because it was a Drupal project rather than other scenarios people described.

My problem was that someone in the project added a js which his address was: <script src="http://base_url/?p4sxbt"></script> and it was attached in this way:

drupal_add_js('',
    array('scope' => 'footer', 'weight' => 5)
  );

Hope this will help someone in the future.

Some people seem to be confusing these macros with assert().

These macros implement a compile-time test, while assert() is a runtime test.

Using absolute as position is not responsive + mobile friendly. I would suggest using a div with a background-image and then placing text in the div will place text over the image. Depending on your html, you might need to use height with vh value

I can't find toByteArray() as @atrioom said, so I use StringWriter, please try:

public void writeListToJsonArray() throws IOException {  

    //your list
    final List<Event> list = new ArrayList<Event>(2);
    list.add(new Event("a1","a2"));
    list.add(new Event("b1","b2"));


    final StringWriter sw =new StringWriter();
    final ObjectMapper mapper = new ObjectMapper();
    mapper.writeValue(sw, list);
    System.out.println(sw.toString());//use toString() to convert to JSON

    sw.close(); 
}

Or just use ObjectMapper#writeValueAsString:

    final ObjectMapper mapper = new ObjectMapper();
    System.out.println(mapper.writeValueAsString(list));

Using obtrusive JavaScript (i.e. inline code) as in your example, you can attach the click event handler to the div element with the onclick attribute like so:

 <div id="some-id" class="some-class" onclick="slideonlyone('sms_box');">
     ...
 </div>

However, the best practice is unobtrusive JavaScript which you can easily achieve by using jQuery's on() method or its shorthand click(). For example:

 $(document).ready( function() {
     $('.some-class').on('click', slideonlyone('sms_box'));
     // OR //
     $('.some-class').click(slideonlyone('sms_box'));
 });

Inside your handler function (e.g. slideonlyone() in this case) you can reference the element that triggered the event (e.g. the div in this case) with the $(this) object. For example, if you need its ID, you can access it with $(this).attr('id').

EDIT

After reading your comment to @fmsf below, I see you also need to dynamically reference the target element to be toggled. As @fmsf suggests, you can add this information to the div with a data-attribute like so:

<div id="some-id" class="some-class" data-target="sms_box">
    ...
</div>

To access the element's data-attribute you can use the attr() method as in @fmsf's example, but the best practice is to use jQuery's data() method like so:

 function slideonlyone() {
     var trigger_id = $(this).attr('id'); // This would be 'some-id' in our example
     var target_id  = $(this).data('target'); // This would be 'sms_box'
     ...
 }

Note how data-target is accessed with data('target'), without the data- prefix. Using data-attributes you can attach all sorts of information to an element and jQuery would automatically add them to the element's data object.

Just install package Synced?Sidebar?Bg:it will change the sidebar theme based on current color scheme.But it seems that every time you change the color scheme,sidebar will be changed after you open file Preferences.sublime-settings

$('#attached_docs [value="123"]').find ... .remove();

it should do your need however, you cannot duplicate id! remember it

Faced same problem in asp.net core Hope this helps

public static class CorsConfig
{
    public static void AddCorsConfig(this IServiceCollection services)
    {
        services.AddCors(options =>
        {
            options.AddPolicy("CorsPolicy",
                builder => builder
                .WithExposedHeaders("X-Pagination")
                );
        });
    }
}

You simply have to set the state of the your button self.x to normal:

self.x['state'] = 'normal'

or

self.x.config(state="normal")

This code would go in the callback for the event that will cause the Button to be enabled.

Also, the right code should be:

self.x = Button(self.dialog, text="Download", state=DISABLED, command=self.download)
self.x.pack(side=LEFT)

The method pack in Button(...).pack() returns None, and you are assigning it to self.x. You actually want to assign the return value of Button(...) to self.x, and then, in the following line, use self.x.pack().

An enum is only guaranteed to be large enough to hold int values. The compiler is free to choose the actual type used based on the enumeration constants defined so it can choose a smaller type if it can represent the values you define. If you need enumeration constants that don't fit into an int you will need to use compiler-specific extensions to do so.

We have a large .SLN files with many project files. I started the policy of having a "ViewLocal" directory where all non-sourcecontrolled files are located. Inside that directory is an 'Inter' and an 'Out' directory. For the intermediate files, and the output files, respectively.

This obviously makes it easy to just go to your 'viewlocal' directory and do a simple delete, to get rid of everything.

Before you spent time figuring out a way to work around this with scripts, you might think about setting up something similar.

I won't lie though, maintaining such a setup in a large organization has proved....interesting. Especially when you use technologies such as QT that like to process files and create non-sourcecontrolled source files. But that is a whole OTHER story!

I solved the problem by using Socket.ConnectAsync Method instead of Socket.Connect Method. After invoking the Socket.ConnectAsync(SocketAsyncEventArgs), start a timer (timer_connection), if time is up, check whether socket connection is connected (if(m_clientSocket.Connected)), if not, pop up timeout error.

private void connect(string ipAdd,string port)
    {
        try
        {
            SocketAsyncEventArgs e=new SocketAsyncEventArgs();


            m_clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

            IPAddress ip = IPAddress.Parse(serverIp);
            int iPortNo = System.Convert.ToInt16(serverPort);
            IPEndPoint ipEnd = new IPEndPoint(ip, iPortNo);

            //m_clientSocket.
            e.RemoteEndPoint = ipEnd;
            e.UserToken = m_clientSocket;
            e.Completed+=new EventHandler<SocketAsyncEventArgs>(e_Completed);                
            m_clientSocket.ConnectAsync(e);

            if (timer_connection != null)
            {
                timer_connection.Dispose();
            }
            else
            {
                timer_connection = new Timer();
            }
            timer_connection.Interval = 2000;
            timer_connection.Tick+=new EventHandler(timer_connection_Tick);
            timer_connection.Start();
        }
        catch (SocketException se)
        {
            lb_connectStatus.Text = "Connection Failed";
            MessageBox.Show(se.Message);
        }
    }
private void e_Completed(object sender,SocketAsyncEventArgs e)
    {
        lb_connectStatus.Text = "Connection Established";
        WaitForServerData();
    }
    private void timer_connection_Tick(object sender, EventArgs e)
    {
        if (!m_clientSocket.Connected)
        {
            MessageBox.Show("Connection Timeout");
            //m_clientSocket = null;

            timer_connection.Stop();
        }
    }

Using Python 2, calling .lower() on each string or Unicode object...

string1.lower() == string2.lower()

...will work most of the time, but indeed doesn't work in the situations @tchrist has described.

Assume we have a file called unicode.txt containing the two strings S?s?f?? and S?S?F?S. With Python 2:

>>> utf8_bytes = open("unicode.txt", 'r').read()
>>> print repr(utf8_bytes)
'\xce\xa3\xce\xaf\xcf\x83\xcf\x85\xcf\x86\xce\xbf\xcf\x82\n\xce\xa3\xce\x8a\xce\xa3\xce\xa5\xce\xa6\xce\x9f\xce\xa3\n'
>>> u = utf8_bytes.decode('utf8')
>>> print u
S?s?f??
S?S?F?S

>>> first, second = u.splitlines()
>>> print first.lower()
s?s?f??
>>> print second.lower()
s?s?f?s
>>> first.lower() == second.lower()
False
>>> first.upper() == second.upper()
True

The S character has two lowercase forms, ? and s, and .lower() won't help compare them case-insensitively.

However, as of Python 3, all three forms will resolve to ?, and calling lower() on both strings will work correctly:

>>> s = open('unicode.txt', encoding='utf8').read()
>>> print(s)
S?s?f??
S?S?F?S

>>> first, second = s.splitlines()
>>> print(first.lower())
s?s?f??
>>> print(second.lower())
s?s?f??
>>> first.lower() == second.lower()
True
>>> first.upper() == second.upper()
True

So if you care about edge-cases like the three sigmas in Greek, use Python 3.

(For reference, Python 2.7.3 and Python 3.3.0b1 are shown in the interpreter printouts above.)

The & operator takes the intersection of two sets.

{1, 2, 3} & {2, 3, 4}
Out[1]: {2, 3}

You are mixing pointers and arrays. If what you want is an array, then use an array:

struct test {
   static int data[10];        // array, not pointer!
};
int test::data[10] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

If on the other hand you want a pointer, the simplest solution is to write a helper function in the translation unit that defines the member:

struct test {
   static int *data;
};
// cpp
static int* generate_data() {            // static here is "internal linkage"
   int * p = new int[10];
   for ( int i = 0; i < 10; ++i ) p[i] = 10*i;
   return p;
}
int *test::data = generate_data();

IN:

• Works on List result set
• Doesn’t work on subqueries resulting in Virtual tables with multiple columns
• Compares every value in the result list
• Performance is comparatively SLOW for larger result set of subquery

EXISTS:

• Works on Virtual tables
• Is used with co-related queries
• Exits comparison when match is found
• Performance is comparatively FAST for larger result set of subquery

Yes, to make it run in the background create a shortcut to the batch file and go into the properties. I'm on a Linux machine ATM but I believe the option you are wanting is in the advanced tab.

You can also run your batch script through a vbs script like this:

'HideBat.vbs
CreateObject("Wscript.Shell").Run "your_batch_file.bat", 0, True

This will execute your batch file with no cmd window shown.

I had the same question and more, and though this thread is old, it is still a good one, so in summary for SSRS 2008R2 I found...

Situations

1. You want to use a value from a URL to look up data
2. You want to display a parameter from a URL in a report
3. You want to pass a parameter from one report to another report

Actions

If applicable, be sure to replace Reports/Pages/Report.aspx?ItemPath= with ReportServer?. In other words: Instead of this:

http://server/Reports/Pages/Report.aspx?ItemPath=/ReportFolder/ReportSubfolder/ReportName

Use this syntax:

http://server/ReportServer?/ReportFolder/ReportSubfolder/ReportName

Add parameter(s) to the report and set as hidden (or visible if user action allowed, though keep in mind that while the report parameter will change, the URL will not change based on an updated entry).

Attach parameters to URL with &ParameterName=Value

Parameters can be referenced or displayed in report using @ParameterName, whether they're set in the report or in the URL

To hide the toolbar where parameters are displayed, add &rc:Toolbar=false to the URL (reference)

Putting that all together, you can run a URL with embedded values, or call this as an action from one report and read by another report:

http://server.domain.com/ReportServer?/ReportFolder1/ReportSubfolder1/ReportName&UserID=ABC123&rc:Toolbar=false

In report dataset properties query: SELECT stuff FROM view WHERE User = @UserID

In report, set expression value to [UserID] (or =Fields!UserID.Value)

Keep in mind that if a report has multiple parameters, you might need to include all parameters in the URL, even if blank, depending on how your dataset query is written.

To pass a parameter using Action = Go to URL, set expression to:

="http://server.domain.com/ReportServer?/ReportFolder1/ReportSubfolder1/ReportName&UserID="
 &Fields!UserID.Value 
 &"&rc:Toolbar=false"
 &"&rs:ClearSession=True"

Be sure to have a space after an expression if followed by & (a line break is isn't enough). No space is required before an expression. This method can pass a parameter but does not hide it as it is visible in the URL.

If you don't include &rs:ClearSession=True then the report won't refresh until browser session cache is cleared.

To pass a parameter using Action = Go to report:

• Specify the report
• Add parameter(s) to run the report
• Add parameter(s) you wish to pass (the parameters need to be defined in the destination report, so to my knowledge you can't use URL-specific commands such as rc:toolbar using this method); however, I suppose it would be possible to read or set the Prompt User checkbox, as seen in reporting sever parameters, through custom code in the report.)

For reference, / = %2f

I was trying these examples without success. Apparently other stylesheets on the page were setting default font sizes for different tags. If you adjust the ui-datepicker you are changing a div. If you change a div you need to make sure the contents of that div inherit that size. This is what finally worked for me:

<style type="text/css">
.ui-datepicker-calendar tr, .ui-datepicker-calendar td, .ui-datepicker-calendar td a, .ui-datepicker-calendar th{font-size:inherit;}
div.ui-datepicker{font-size:16px;width:inherit;height:inherit;}
.ui-datepicker-title span{font-size:16px;}
</style>

Good luck!

Well you could directly substract from the value by just referencing the key. Which in my opinion is simpler.

>>> books = {}
>>> books['book'] = 3       
>>> books['book'] -= 1   
>>> books   
{'book': 2}   

In your case:

book_shop[ch1] -= 1

public String formatStr(float val) {
 return String.format(Locale.CANADA, "%,.2f", val);
}

formatStr(2524.2) // 2,254.20
