Programs & Examples On #Wmi query

A DataTable or DataSet object will have a Select Method that will return a DataRow array of results based on the query passed in as it's parameter.

Looking at your requirement your filterexpression will have to be somewhat general to make this work.

myDataTable.Select("columnName1 like '%" + value + "%'");

A standard-lib version (no pandas)

This assumes that the first row of the csv is the headers

import csv

# open the file in universal line ending mode 
with open('test.csv', 'rU') as infile:
  # read the file as a dictionary for each row ({header : value})
  reader = csv.DictReader(infile)
  data = {}
  for row in reader:
    for header, value in row.items():
      try:
        data[header].append(value)
      except KeyError:
        data[header] = [value]

# extract the variables you want
names = data['name']
latitude = data['latitude']
longitude = data['longitude']

ES6 way.

export in foo.js

const FOO = 'bar';
module.exports = {
  FOO
}

import in bar.js

const {FOO} = require('foo');

if your application accepts errors raise from Oracle, then you can use it. we have an application, each time when an error happens, we call raise_application_error, the application will popup a red box to show the error message we provide through this method.

When using dotnet code, I just use "raise", dotnet exception mechanisim will automatically capture the error passed by Oracle ODP and shown inside my catch exception code.

In Oracle, to insert multiple rows into table t with columns col1, col2 and col3 you can use the following syntax:

INSERT ALL
   INTO t (col1, col2, col3) VALUES ('val1_1', 'val1_2', 'val1_3')
   INTO t (col1, col2, col3) VALUES ('val2_1', 'val2_2', 'val2_3')
   INTO t (col1, col2, col3) VALUES ('val3_1', 'val3_2', 'val3_3')
   .
   .
   .
SELECT 1 FROM DUAL;

I don't know if VB.net in VS 2008 is any different, but none of the above worked for me. Double-clicking My Project in Solution Explorer brings up the window seen below. Select Application on the left, then browse for your icon using the combobox. After you build, it should show up on your exe file.

The key is git submodules.

Start reading the Submodules chapter of the Git Community Book or of the Users Manual

Say you have repository PROJECT1, PROJECT2, and MEDIA...

cd /path/to/PROJECT1
git submodule add ssh://path.to.repo/MEDIA
git commit -m "Added Media submodule"

Repeat on the other repo...

Now, the cool thing is, that any time you commit changes to MEDIA, you can do this:

cd /path/to/PROJECT2/MEDIA
git pull
cd ..
git add MEDIA
git commit -m "Upgraded media to version XYZ"

This just recorded the fact that the MEDIA submodule WITHIN PROJECT2 is now at version XYZ.

It gives you 100% control over what version of MEDIA each project uses. git submodules are great, but you need to experiment and learn about them.

With great power comes the great chance to get bitten in the rump.

All you'd need in your case is:

return expression;

The reason why is that the expression itself evaluates to a boolean value of true or false, so it's redundant to have an if block (or even a ?: operator).

import cv2
camera = cv2.VideoCapture(0)
while True:
    return_value,image = camera.read()
    gray = cv2.cvtColor(image,cv2.COLOR_BGR2GRAY)
    cv2.imshow('image',gray)
    if cv2.waitKey(1)& 0xFF == ord('s'):
        cv2.imwrite('test.jpg',image)
        break
camera.release()
cv2.destroyAllWindows()

What you asked for is:

IF OBJECT_ID('tempdb..##CLIENTS_KEYWORD') IS NOT NULL
    BEGIN
       DROP TABLE ##CLIENTS_KEYWORD

       CREATE TABLE ##CLIENTS_KEYWORD(client_id int)

    END
ELSE
   CREATE TABLE ##CLIENTS_KEYWORD(client_id int) 

IF OBJECT_ID('tempdb..##TEMP_CLIENTS_KEYWORD') IS NOT NULL
    BEGIN
       DROP TABLE ##TEMP_CLIENTS_KEYWORD

       CREATE TABLE ##TEMP_CLIENTS_KEYWORD(client_id int)

    END
ELSE
   CREATE TABLE ##TEMP_CLIENTS_KEYWORD(client_id int) 

Since you're always going to create the table, regardless of whether the table is deleted or not; a slightly optimised solution is:

IF OBJECT_ID('tempdb..##CLIENTS_KEYWORD') IS NOT NULL
   DROP TABLE ##CLIENTS_KEYWORD

CREATE TABLE ##CLIENTS_KEYWORD(client_id int) 

IF OBJECT_ID('tempdb..##TEMP_CLIENTS_KEYWORD') IS NOT NULL
   DROP TABLE ##TEMP_CLIENTS_KEYWORD

CREATE TABLE ##TEMP_CLIENTS_KEYWORD(client_id int) 

I've searched through their docs and it seems there is not xpath option. Also, as you can see here on a similar question on SO, the OP is asking for a translation from xpath to BeautifulSoup, so my conclusion would be - no, there is no xpath parsing available.

Since Spring Boot v2+

I have verified with Spring Boot v2.3.5.RELEASE

With Spring Boot Maven Plugin

You can provide commandline argument like this:

mvn spring-boot:run -Dspring-boot.run.arguments="--spring.profiles.active=dev"

You can provide JVM argument like this:

mvn spring-boot:run -Dspring-boot.run.jvmArguments="-Dspring.profiles.active=dev"

java -jar

java -Dspring.profiles.active=dev -jar app.jar (Note order)

or

java -jar app.jar --spring.profiles.active=dev (Note order)

I know this is ancient however when dealing with finicky tools, uses, users or symptoms re: sid & service naming one can add a little flex to your tnsnames entries as like:

mySID, mySID.whereever.com =
(DESCRIPTION =
  (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = myHostname)(PORT = 1521))
  )
  (CONNECT_DATA =
    (SERVICE_NAME = mySID.whereever.com)
    (SID = mySID)
    (SERVER = DEDICATED)
  )
)

I just thought I'd leave this here as it's mildly relevant to the question and can be helpful when attempting to weave around some less than clear idiosyncrasies of oracle networking.

After use codevar json = @Html.Raw(Json.Encode(@Model.CollegeInformationlist));

You need use JSON.parse(JSON.stringify(json));

Moving Dylan's comment into a full-blown answer because TOO USEFUL:

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock assaflavie/runlike YOUR-CONTAINER

What does it do? Runs https://github.com/lavie/runlike inside a container, gets you the complete docker run command, then removes the container for you.

Non-identifying relationship

A non-identifying relationship means that a child is related to parent but it can be identified by its own.

PERSON    ACCOUNT
======    =======
pk(id)    pk(id)
name      fk(person_id)
          balance

The relationship between ACCOUNT and PERSON is non-identifying.

Identifying relationship

An identifying relationship means that the parent is needed to give identity to child. The child solely exists because of parent.

This means that foreign key is a primary key too.

ITEM      LANGUAGE    ITEM_LANG
====      ========    =========
pk(id)    pk(id)      pk(fk(item_id))
name      name        pk(fk(lang_id))
                      name

The relationship between ITEM_LANG and ITEM is identifying. And between ITEM_LANG and LANGUAGE too.

You have 2 issues here.

1. use == for comparison. You've used = which is for assignment.

2. use && for "and" and || for "or". and and or will work but they are unconventional.

If you write an unmanaged program and use CreateProcess API then you should initialize lpStartupInfo parameter of the type STARTUPINFO so that wShowWindow field of the struct is SW_HIDE and not forget to use STARTF_USESHOWWINDOW flag in the dwFlags field of STARTUPINFO. Another method is to use CREATE_NO_WINDOW flag of dwCreationFlags parameter. The same trick work also with ShellExecute and ShellExecuteEx functions.

If you write a managed application you should follows advices from http://blogs.msdn.com/b/jmstall/archive/2006/09/28/createnowindow.aspx: initialize ProcessStartInfo with CreateNoWindow = true and UseShellExecute = false and then use as a parameter of . Exactly like in case of you can set property WindowStyle of ProcessStartInfo to ProcessWindowStyle.Hidden instead or together with CreateNoWindow = true.

You can use a VBS script which you start with wcsript.exe. Inside the script you can use CreateObject("WScript.Shell") and then Run with 0 as the second (intWindowStyle) parameter. See http://www.robvanderwoude.com/files/runnhide_vbs.txt as an example. I can continue with Kix, PowerShell and so on.

If you don't want to write any program you can use any existing utility like CMDOW /RUN /HID "c:\SomeDir\MyBatch.cmd", hstart /NOWINDOW /D=c:\scripts "c:\scripts\mybatch.bat", hstart /NOCONSOLE "batch_file_1.bat" which do exactly the same. I am sure that you will find much more such kind of free utilities.

In some scenario (for example starting from UNC path) it is important to set also a working directory to some local path (%SystemRoot%\system32 work always). This can be important for usage any from above listed variants of starting hidden batch.

You could use the printf(1) command, e.g. like

printf "Hello times %d\nHere\n" $[2+3] 

The  printf command may accept arguments and needs a format control string similar (but not exactly the same) to the one for the standard C printf(3) function...

Use this function and don't sweat having to remember if your JSON is a str or dict again - just look at the pretty print:

import json

def pp_json(json_thing, sort=True, indents=4):
    if type(json_thing) is str:
        print(json.dumps(json.loads(json_thing), sort_keys=sort, indent=indents))
    else:
        print(json.dumps(json_thing, sort_keys=sort, indent=indents))
    return None

pp_json(your_json_string_or_dict)

There is simple way to do it if you fear Javascript...I'm still learning. Open Street makes a simple Wordpress plugin you can customize. Add OSM Widget plugin.

This will be a filler until I figure out my Python Java concotion using coverter TIGER line files from the Census Bureau.

Try this

ALTER DATABASE XXXX  SET RECOVERY SIMPLE

use XXXX

declare @log_File_Name varchar(200) 

select @log_File_Name  = name from sysfiles where filename like '%LDF'

declare @i int = FILE_IDEX ( @log_File_Name)

dbcc shrinkfile ( @i , 50) 

It is matter of performance and memory usage, compile and keep the complied pattern if you need to use it a lot. A typical usage of regex is to validated user input (format), and also format output data for users, in these classes, saving the complied pattern, seems quite logical as they usually called a lot.

Below is a sample validator, which is really called a lot :)

public class AmountValidator {
    //Accept 123 - 123,456 - 123,345.34
    private static final String AMOUNT_REGEX="\\d{1,3}(,\\d{3})*(\\.\\d{1,4})?|\\.\\d{1,4}";
    //Compile and save the pattern  
    private static final Pattern AMOUNT_PATTERN = Pattern.compile(AMOUNT_REGEX);


    public boolean validate(String amount){

         if (!AMOUNT_PATTERN.matcher(amount).matches()) {
            return false;
         }    
        return true;
    }    
}

As mentioned by @Alan Moore, if you have reusable regex in your code, (before a loop for example), you must compile and save pattern for reuse.

See full query from SHOW PROCESSLIST :

SHOW FULL PROCESSLIST;

Or

 SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST;

Even more concise if you are on python 2.7:

>>> t = ((1,'a'),(2,'b'))
>>> {y:x for x,y in t}
{'a':1, 'b':2}

DECLARE   @UserOptions TABLE(SetOption varchar(100), Value varchar(100))
DECLARE   @IsolationLevel varchar(100)

INSERT    @UserOptions
EXEC('DBCC USEROPTIONS WITH NO_INFOMSGS')

SELECT    @IsolationLevel = Value
FROM      @UserOptions
WHERE     SetOption = 'isolation level'

-- Do whatever you want with the variable here...  
PRINT     @IsolationLevel

$('div.alldivs :first-child');

Or you can just refer to the id directly:

$('#div1');

As suggested, you might be better of using the child selector:

$('div.alldivs > div:first-child')

If you dont have to use first-child, you could use :first as also suggested, or $('div.alldivs').children(0).

I tried:

import os
os.path.abspath(os.path.join(os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe()))), os.pardir))

As an alternative to @Mark Byers' approach, you can use while True:

guess = 50     # this should be outside the loop, I think
while True:    # infinite loop
    n = raw_input("\n\nTrue, False or Correct?: ")
    if n == "Correct":
        break  # stops the loop
    elif n == "True":
        # etc.

For newer versions of Eclipse:

1. open the Debug perspective (Window > Open Perspective > Debug)

2. select process in Devices list (bottom right)

3. Hit Stop button (top right of Devices pane)

Actually, I've got a bit more precise solution, which might be useful if you don't want to change/delete anything else.

Run regedit, and at the HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome key you should have a PasswordManagerEnabled property, which probably is set to 0.

Simply change it to 1.

Edit: I tried it on some other computer and it didn't want to work, so I rebooted my computer, made sure Chrome is closed, then changed it in the registry, and finally it worked. So make sure Chrome is closed when you do this.

import difflib
f=open('a.txt','r')  #open a file
f1=open('b.txt','r') #open another file to compare
str1=f.read()
str2=f1.read()
str1=str1.split()  #split the words in file by default through the spce
str2=str2.split()
d=difflib.Differ()     # compare and just print
diff=list(d.compare(str2,str1))
print '\n'.join(diff)

Arrays.asList(array)

Arrays uses new ArrayList(array). But this is not the java.util.ArrayList. It's very similar though. Note that this constructor takes the array and places it as the backing array of the list. So it is O(1).

In case you already have the list created, Collections.addAll(list, array), but that's less efficient.

Update: Thus your Collections.addAll(list, array) becomes a good option. A wrapper of it is guava's Lists.newArrayList(array).

To make it clear, in addition to @SLaks' answer, that meant you need to change this line :

List<RootObject> datalist = JsonConvert.DeserializeObject<List<RootObject>>(jsonstring);

to something like this :

RootObject datalist = JsonConvert.DeserializeObject<RootObject>(jsonstring);

Swift 2.x answer:

    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)) {
        self.getResultSetFromDB(docids)
    }

To answer the exact question of finding a free port (which is what I needed in my unit tests) in dotnet core 3.1 I came up this

public static int GetAvailablePort(IPAddress ip) {
        TcpListener l = new TcpListener(ip, 0);
        l.Start();
        int port = ((IPEndPoint)l.LocalEndpoint).Port;
        l.Stop();
        Log.Info($"Available port found: {port}");
        return port;
    }

note: based the comment by @user207421 about port zero I searched and found this and slightly modified it.

use the accepted answer / this was the answer to another (already deleted) question

@karopastal

add a ref attribute to your <TextField /> component and call getValue() on it, like this:

Component:

<TextField ref="myField" />

Using getValue:

this.refs.myField.getValue()

If we are use chosen dropdown list, then we can use below css(No JS/JQuery require)

<select chosen="{width: '100%'}" ng- 
   model="modelName" class="form-control input- 
   sm"
   ng- 
   options="persons.persons as 
   persons.persons for persons in 
   jsonData"
   ng- 
   change="anyFunction(anyParam)" 
   required>
   <option value=""> </option>
</select>
<style>   
.chosen-container .chosen-drop {
    border-bottom: 0;
    border-top: 1px solid #aaa;
    top: auto;
    bottom: 40px;
}

.chosen-container.chosen-with-drop .chosen-single {
    border-top-left-radius: 0px;
    border-top-right-radius: 0px;

    border-bottom-left-radius: 5px;
    border-bottom-right-radius: 5px;

    background-image: none;
}

.chosen-container.chosen-with-drop .chosen-drop {
    border-bottom-left-radius: 0px;
    border-bottom-right-radius: 0px;

    border-top-left-radius: 5px;
    border-top-right-radius: 5px;

    box-shadow: none;

    margin-bottom: -16px;
}
</style>

$suborder['payment_date'] = Carbon::parse($item['created_at'])->format('M d Y');

Another option

min.getTime() <= d.getTime() && d.getTime() <= max.getTime()

the above guy was close but here is what you want:

       var table = document.getElementById(tableID);
       var rowCount = table.rows.length;        
         for (var r = 0, n = table.rows.length; r < n; r++) {
        for (var c = 0, m = table.rows[r].cells.length; c < m; c++) {
            alert(table.rows[r].cells[c].firstChild.value);
        }
    }
        }catch(e) {
            alert(e);
        }

CREATE TABLE Orders(
    O_Id int NOT NULL,
    OrderNo int NOT NULL,
    P_Id int,
    OrderDate date DEFAULT GETDATE() // you can set default constraints while creating the table
)

How about:

df['D'] = df['B'].values

You should probably read some JS tutorials like this one.

Not sure if goto exists in JS at all, but, either way, it encourages bad coding style and should be avoided.

You could do:

while ( some_condition ){
    alert('RINSE');
    alert('LATHER');
}

Here is how you do it: Simple way

// Initializing a new alert dialog
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setMessage(R.string.message);
builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        doAction();
    }
});
builder.setNegativeButton(R.string.cancel, null);

// Create the alert dialog and change Buttons colour
AlertDialog dialog = builder.create();
dialog.setOnShowListener(new DialogInterface.OnShowListener() {
    @Override
    public void onShow(DialogInterface arg0) {
        dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(getResources().getColor(R.color.red));
        dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(getResources().getColor(R.color.blue));
        //dialog.getButton(AlertDialog.BUTTON_NEUTRAL).setTextColor(getResources().getColor(R.color.black));
    }
});
dialog.show();

You can take a look at InterpolatedUnivariateSpline

Here an example using it:

import matplotlib.pyplot as plt
import numpy as np
from scipy.interpolate import InterpolatedUnivariateSpline

# given values
xi = np.array([0.2, 0.5, 0.7, 0.9])
yi = np.array([0.3, -0.1, 0.2, 0.1])
# positions to inter/extrapolate
x = np.linspace(0, 1, 50)
# spline order: 1 linear, 2 quadratic, 3 cubic ... 
order = 1
# do inter/extrapolation
s = InterpolatedUnivariateSpline(xi, yi, k=order)
y = s(x)

# example showing the interpolation for linear, quadratic and cubic interpolation
plt.figure()
plt.plot(xi, yi)
for order in range(1, 4):
    s = InterpolatedUnivariateSpline(xi, yi, k=order)
    y = s(x)
    plt.plot(x, y)
plt.show()

I have faced same problem. I followed the approved answer. I have done but it was not working, because my keyboard format was different. It was in Bengali keyboard. But later I have changed my keyboard layout and tried in this way.

Resharper > Options > Keyboard & Menus > Apply scheme > Save.

Then it was working fine. But whenever I change my keyboard English-US to Bengali then it changes again and I need to do reconfigure.

Java native code necessities:

• h/w access and control.
• use of commercial s/w and system services[h/w related].
• use of legacy s/w that hasn't or cannot be ported to Java.
• Using native code to perform time-critical tasks.

hope these points answers your question :)

A much easier way is to go to Data and select Group or Subtotal. Instant collapsible rows without messing with pivot tables or VBA.

I thought it would be valuable to summarize and compare the given answers.

If you want to access the environment variable:

(easier/shorter/memorable option)

• [Environment]::UserName -- @ThomasBratt
• $env:username -- @Eoin
• whoami -- @galaktor

If you want to access the Windows access token:

(more dependable option)

• [System.Security.Principal.WindowsIdentity]::GetCurrent().Name -- @MarkSeemann

If you want the name of the logged in user

(rather than the name of the user running the PowerShell instance)

• $(Get-WMIObject -class Win32_ComputerSystem | select username).username -- @TwonOfAn on this other forum

Comparison

@Kevin Panko's comment on @Mark Seemann's answer deals with choosing one of the categories over the other:

[The Windows access token approach] is the most secure answer, because $env:USERNAME can be altered by the user, but this will not be fooled by doing that.

In short, the environment variable option is more succinct, and the Windows access token option is more dependable.

I've had to use @Mark Seemann's Windows access token approach in a PowerShell script that I was running from a C# application with impersonation.

The C# application is run with my user account, and it runs the PowerShell script as a service account. Because of a limitation of the way I'm running the PowerShell script from C#, the PowerShell instance uses my user account's environment variables, even though it is run as the service account user.

In this setup, the environment variable options return my account name, and the Windows access token option returns the service account name (which is what I wanted), and the logged in user option returns my account name.

Testing

Also, if you want to compare the options yourself, here is a script you can use to run a script as another user. You need to use the Get-Credential cmdlet to get a credential object, and then run this script with the script to run as another user as argument 1, and the credential object as argument 2.

Usage:

$cred = Get-Credential UserTo.RunAs
Run-AsUser.ps1 "whoami; pause" $cred
Run-AsUser.ps1 "[System.Security.Principal.WindowsIdentity]::GetCurrent().Name; pause" $cred

Contents of Run-AsUser.ps1 script:

param(
  [Parameter(Mandatory=$true)]
  [string]$script,
  [Parameter(Mandatory=$true)]
  [System.Management.Automation.PsCredential]$cred
)

Start-Process -Credential $cred -FilePath 'powershell.exe' -ArgumentList 'noprofile','-Command',"$script"

There is a visual studio plugin to support the java language: http://visualstudiogallery.msdn.microsoft.com/bc561769-36ff-4a40-9504-e266e8706f93

Along with Environment.NewLine and the literal \r\n or just \n you may also use a verbatim string in C#. These begin with @ and can have embedded newlines. The only thing to keep in mind is that " needs to be escaped as "". An example:

string s = @"This is a string
that contains embedded new lines,
that will appear when this string is used."

This is an improvement over the accepted answer.

You can use NetEm (Network Emulation) as a proxy server to emulate many network characteristics (speed, delay, packet loss, etc.). It controls the networking using iproute2 package and it's enabled in the kernel of the most Linux distributions.

It is controlled by the tc command-line application (from the iproute2 package), but there are also some web interface GUIs for NetEm, for example PHPnetemGUI2.

The advantage is that, as I wrote, it can emulate not only different network speeds but also, for example, the packet loss, duplication and/or corruption, random or defined delay, etc., so you can emulate various poorly performing networks.

For your application it's absolutely transparent, you can configure the operating system to use the NetEm proxy server, so all connections from that machine will go trough NetEm. Or you can configure only your application to use it as a proxy.

I have been using it to test the performance of an Android app on various emulated poor-performance networks.

This will do what you want but I don't know about performance:

var distinctValues =
    from cust in myCustomerList
    group cust by cust.CustomerId
    into gcust
    select gcust.First();

At least it's not verbose.

My solution is to cover all the range of diacritics:

([A-z0-9À-ž\s]){2,}

A-z - this is for all latin characters

0-9 - this is for all digits

À-ž - this is for all diacritics

\s - this is for spaces

{2,} - string needs to be at least 2 characters long

Looking for EventHandling, ActionListener?

or code?

JButton b = new JButton("Clear");
b.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent e){
        textfield.setText("");
        //textfield.setText(null); //or use this
    }

It depends on whether the setting you have chosen is at "User" scope or "Application" scope.

User scope

User scope settings are stored in

C:\Documents and Settings\ username \Local Settings\Application Data\ ApplicationName

You can read/write them at runtime.

For Vista and Windows 7, folder is

C:\Users\ username \AppData\Local\ ApplicationName

or

C:\Users\ username \AppData\Roaming\ ApplicationName

Application scope

Application scope settings are saved in AppName.exe.config and they are readonly at runtime.

Negatives are your friend here:

SELECT Col1
FROM TABLE
WHERE Col1 like '%[^a-Z0-9]%'

Which says that you want any rows where Col1 consists of any number of characters, then one character not in the set a-Z0-9, and then any number of characters.

If you have a case sensitive collation, it's important that you use a range that includes both upper and lower case A, a, Z and z, which is what I've given (originally I had it the wrong way around. a comes before A. Z comes after z)

Or, to put it another way, you could have written your original WHERE as:

Col1 LIKE '[!@#$%]'

But, as you observed, you'd need to know all of the characters to include in the [].

Add this line in style of v21 if you use two style.

  <item name="android:statusBarColor">#43434f</item>

You should use GlassFish for Java EE enterprise applications. Some things to consider:

A web Server means: Handling HTTP requests (usually from browsers).

A Servlet Container (e.g. Tomcat) means: It can handle servlets & JSP.

An Application Server (e.g. GlassFish) means: *It can manage Java EE applications (usually both servlet/JSP and EJBs).

Tomcat - is run by Apache community - Open source and has two flavors:

1. Tomcat - Web profile - lightweight which is only servlet container and does not support Java EE features like EJB, JMS etc.
2. Tomcat EE - This is a certified Java EE container, this supports all Java EE technologies.

No commercial support available (only community support)

JBoss - Run by RedHat This is a full-stack support for JavaEE and it is a certified Java EE container. This includes Tomcat as web container internally. This also has two flavors:

1. Community version called Application Server (AS) - this will have only community support.
2. Enterprise Application Server (EAP) - For this, you can have a subscription-based license (It's based on the number of Cores you have on your servers.)

Glassfish - Run by Oracle This is also a full stack certified Java EE Container. This has its own web container (not Tomcat). This comes from Oracle itself, so all new specs will be tested and implemented with Glassfish first. So, always it would support the latest spec. I am not aware of its support models.

A GUID is a 128 bit integer (its just in hex rather than base 10). With .NET 4 use http://msdn.microsoft.com/en-us/library/dd268285%28v=VS.100%29.aspx like so:

// Turn a GUID into a string and strip out the '-' characters.
BigInteger huge = BigInteger.Parse(modifiedGuidString, NumberStyles.AllowHexSpecifier)

If you don't have .NET 4 you can look at IntX or Solver Foundation.

• On a 64-bit machine, copy "msvcr71.dll" from C:\Windows\SysWOW64 to the bin directory for your application.
• On a 32-bit machine, copy "msvcr71.dll" from C:\Windows\System32 to the bin directory for your application.

Represent it as a text entity (ASCII 39):

<input type='text' id='abc' value='hel&#39;lo'>

TL;DR: Set CURLOPT_PROXYTYPE to use CURLPROXY_SOCKS5_HOSTNAME if you have a modern PHP, the value 7 otherwise, and/or correct the CURLOPT_PROXY value.

As you correctly deduced, you cannot resolve .onion domains via the normal DNS system, because this is a reserved top-level domain specifically for use by Tor and such domains by design have no IP addresses to map to.

Using CURLPROXY_SOCKS5 will direct the cURL command to send its traffic to the proxy, but will not do the same for domain name resolution. The DNS requests, which are emitted before cURL attempts to establish the actual connection with the Onion site, will still be sent to the system's normal DNS resolver. These DNS requests will surely fail, because the system's normal DNS resolver will not know what to do with a .onion address unless it, too, is specifically forwarding such queries to Tor.

Instead of CURLPROXY_SOCKS5, you must use CURLPROXY_SOCKS5_HOSTNAME. Alternatively, you can also use CURLPROXY_SOCKS4A, but SOCKS5 is much preferred. Either of these proxy types informs cURL to perform both its DNS lookups and its actual data transfer via the proxy. This is required to successfully resolve any .onion domain.

There are also two additional errors in the code in the original question that have yet to be corrected by previous commenters. These are:

• Missing semicolon at end of line 1.
• The proxy address value is set to an HTTP URL, but its type is SOCKS; these are incompatible. For SOCKS proxies, the value must be an IP or domain name and port number combination without a scheme/protocol/prefix.

Here is the correct code in full, with comments to indicate the changes.

<?php
$url = 'http://jhiwjjlqpyawmpjx.onion/'; // Note the addition of a semicolon.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_PROXY, "127.0.0.1:9050"); // Note the address here is just `IP:port`, not an HTTP URL.
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5_HOSTNAME); // Note use of `CURLPROXY_SOCKS5_HOSTNAME`.
$output = curl_exec($ch);
$curl_error = curl_error($ch);
curl_close($ch);

print_r($output);
print_r($curl_error);

You can also omit setting CURLOPT_PROXYTYPE entirely by changing the CURLOPT_PROXY value to include the socks5h:// prefix:

// Note no trailing slash, as this is a SOCKS address, not an HTTP URL.
curl_setopt(CURLOPT_PROXY, 'socks5h://127.0.0.1:9050');

Attaches a change event to the select that gets the text for each selected option and writes them in the div.

You can use jQuery it very face and successful and easy to use

<select name="sweets" multiple="multiple">
  <option>Chocolate</option>
  <option>Candy</option>
  <option>Taffy</option>
  <option selected="selected">Caramel</option>
  <option>Fudge</option>
  <option>Cookie</option>
</select>
<div></div>


$("select").change(function () {
  var str = "";

  $("select option:selected").each(function() {
    str += $( this ).text() + " ";
  });

  $( "div" ).text( str );
}).change();

You can add the rules based on that selector using .rules("add", options), just remove any rules you want class based out of your validate options, and after calling $(".formToValidate").validate({... });, do this:

$(".checkBox").rules("add", { 
  required:true,  
  minlength:3
});

Bower maintains a single version of modules, it only tries to help you select the correct/best one for you.

Javascript dependency management : npm vs bower vs volo?

NPM is better for node modules because there is a module system and you're working locally. Bower is good for the browser because currently there is only the global scope, and you want to be very selective about the version you work with.

console.log($.datepicker.formatDate('yy/mm/dd', new Date()));

  $(function () {
    $('.datetimepicker').datetimepicker(
      {
        format: 'Y-m-d h:m:s'
     }
    );
 });`

modified $.each function

$.fn.eachReturn = function(arr, callback) {
   var result = null;
   $.each(arr, function(index, value){
       var test = callback(index, value);
       if (test) {
           result = test;
           return false;
       }
   });
   return result ;
}

it will break loop on non-false/non-empty result and return it back, so in your case it would be

return $.eachReturn(someArray, function(i){
    ...

There's a book in Martin Fowler's Signature Series called Refactoring Databases. That provides a list of techniques for refactoring databases. I can't say I've heard a list of database patterns so much.

I would also highly recommend David C. Hay's Data Model Patterns and the follow up A Metadata Map which builds on the first and is far more ambitious and intriguing. The Preface alone is enlightening.

Also a great place to look for some pre-canned database models is Len Silverston's Data Model Resource Book Series Volume 1 contains universally applicable data models (employees, accounts, shipping, purchases, etc), Volume 2 contains industry specific data models (accounting, healthcare, etc), Volume 3 provides data model patterns.

Finally, while this book is ostensibly about UML and Object Modelling, Peter Coad's Modeling in Color With UML provides an "archetype" driven process of entity modeling starting from the premise that there are 4 core archetypes of any object/data model

Probably the easiest to hide a div and show a div in PHP based on a variables and the operator.

<?php 
$query3 = mysql_query($query3);
$numrows = mysql_num_rows($query3);
?>
<html>
<?php if($numrows > null){ ?>
     no meow :-(
<?php } ?>

<?php if($numrows < null){ ?>
     lots of meow
<?php } ?>
</html>

Here is my original code before adding your requirements:

<?php 
$address = 'meow';
?>
<?php if($address == null){ ?>
     no meow :-(
<?php } ?>

<?php if($address != null){ ?>
     lots of meow
<?php } ?>

If you are using Python2.6 or newer, it's convenient to use socket.create_connection

sock = socket.create_connection(address, timeout=10)
sock.settimeout(None)
fileobj = sock.makefile('rb', 0)

Removing ./ from source path should resolve your issue:

 COPY test.json /home/test.json
 COPY test.py /home/test.py

<script type="text/javascript">
function showDiv(toggle){
document.getElementById(toggle).style.display = 'block';
}
</script>

<input type="button" name="answer" onclick="showDiv('toggle')">Show</input>

<div id="toggle" style="display:none">Hello</div>

In case Translate works locally but not remotly e.i group.Translate(typeof(NTAccount)

If you want to have the application code executes using the LOGGED IN USER identity, then enable impersonation. Impersonation can be enabled thru IIS or by adding the following element in the web.config.

<system.web>
<identity impersonate="true"/>

If impersonation is enabled, the application executes using the permissions found in your user account. So if the logged in user has access, to a specific network resource, only then will he be able to access that resource thru the application.

Thank PRAGIM tech for this information from his diligent video

Windows authentication in asp.net Part 87:

https://www.youtube.com/watch?v=zftmaZ3ySMc

But impersonation creates a lot of overhead on the server

The best solution to allow users of certain network groups is to deny anonymous in the web config <authorization><deny users="?"/><authentication mode="Windows"/>

and in your code behind, preferably in the global.asax, use the HttpContext.Current.User.IsInRole :

Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)
If HttpContext.Current.User.IsInRole("TheDomain\TheGroup") Then
//code to do when user is in group
End If

NOTE: The Group must be written with a backslash \ i.e. "TheDomain\TheGroup"

This code is working for blur effect for all browsers.

filter: blur(10px);
-webkit-filter: blur(10px);
-moz-filter: blur(10px);
-o-filter: blur(10px);
-ms-filter: blur(10px);

Yes, easy. Just run a data-definition query to update the tables, adding an AUTO_INCREMENT column.

If you have an existing database, be careful to preserve any foreign-key relationships that might already be there on the "artificially created" primary keys.

I use following to clear session and clear aspnet_sessionID:

HttpContext.Current.Session.Clear();
HttpContext.Current.Session.Abandon();
HttpContext.Current.Response.Cookies.Add(new HttpCookie("ASP.NET_SessionId", ""));

I sort of fixed it by using the following code:

$("#editor").live('input paste',function(e){
    if(e.target.id == 'editor') {
        $('<textarea></textarea>').attr('id', 'paste').appendTo('#editMode');
        $("#paste").focus();
        setTimeout($(this).paste, 250);
    }
});

Now I just need to store the caret location and append to that position then I'm all set... I think :)

This is a recursive version (i.e. it finds the most recently updated file in a certain directory or any of its subdirectory)

find $DIR -type f -printf "%T@ %p\n" | sort -n | cut -d' ' -f 2- | tail -n 1

Edit: use -f 2- instead of -f 2 as suggested by Kevin

First, don't. Avoid this sort of code. It tends to be really bad code and insecure too (see section 6 of Secure Coding Guidelines for the Java Programming Language, version 2.0).

If you must do it, prefer java.beans to reflection. Beans wraps reflection allowing relatively safe and conventional access.

String strOut = str.substring(0, 8) + "...";

I recommend using the moment.js library (http://momentjs.com/docs/#/displaying/difference/). It handles daylight savings time correctly and in general is great to work with.

Example:

var start = moment("2013-11-03");
var end = moment("2013-11-04");
end.diff(start, "days")

better way is to reuse ANDROID_HOME variable in path variable. if your ANDROID_HOME variable changes you just have to make change at one place.

export ANDROID_HOME=/home/arshid/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

That also happened to me on a recreated directory, the directory is the same but to make it work again just run:

cd .

Really easy solve. Tested and working. You just need to generate a new url when you update your meta tags. It's as simple as adding a "&cacheBuster=1" to your url. If you change the meta tags, just increment the "&cacheBuster=2"

Orginal URL

www.example.com

URL when og meta tags are updated:

www.example.com?cacheBuster=1

URL when og meta tags are updated again:

www.example.com?cacheBuster=2

Facebook will treat each like a new url and get fresh meta data.

If you did a new or clean install of OS X version 10.3 or more recent, the default user terminal shell is bash.

Bash is essentially an enhanced and GNU freeware version of the original Bourne shell, sh. If you have previous experience with bash (often the default on GNU/Linux installations), this makes the OS X command-line experience familiar, otherwise consider switching your shell either to tcsh or to zsh, as some find these more user-friendly.

If you upgraded from or use OS X version 10.2.x, 10.1.x or 10.0.x, the default user shell is tcsh, an enhanced version of csh('c-shell'). Early implementations were a bit buggy and the programming syntax a bit weird so it developed a bad rap.

There are still some fundamental differences between mac and linux as Gordon Davisson so aptly lists, for example no useradd on Mac and ifconfig works differently.

The following table is useful for knowing the various unix shells.

sh      The original Bourne shell   Present on every unix system 
ksh     Original Korn shell         Richer shell programming environment than sh 
csh     Original C-shell            C-like syntax; early versions buggy 
tcsh    Enhanced C-shell            User-friendly and less buggy csh implementation 
bash    GNU Bourne-again shell      Enhanced and free sh implementation 
zsh     Z shell                     Enhanced, user-friendly ksh-like shell

On a final note, I am on Linux (Ubuntu 11) and Mac osX so I use bash and the thing I like the most is customizing the .bashrc (source'd from .bash_profile on OSX) file with aliases, some examples below. I now placed all my aliases in a separate .bash_aliases file and include it with:

if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi

in the .bashrc or .bash_profile file.

Note that this is an example of a mac-linux difference because on a Mac you can't have the --color=auto. The first time I did this (without knowing) I redefined ls to be invalid which was a bit alarming until I removed --auto-color !

String date="Sat Jun 01 12:53:10 IST 2013";

SimpleDateFormat sdf=new SimpleDateFormat("MMM d, yyyy HH:mm:ss");

This patterns does not tally with your input String which occurs the exception.

You need to use following pattern to get the work done.

E MMM dd HH:mm:ss z yyyy

Following code will help you to skip the exception.

SimpleDateFormat is used.

    String date="Sat Jun 01 12:53:10 IST 2013"; // Input String

    SimpleDateFormat simpleDateFormat=new SimpleDateFormat("E MMM dd HH:mm:ss z yyyy"); // Existing Pattern

    Date currentdate=simpleDateFormat.parse(date); // Returns Date Format,

    SimpleDateFormat simpleDateFormat1=new SimpleDateFormat("MMM dd,yyyy HH:mm:ss"); // New Pattern

    System.out.println(simpleDateFormat1.format(currentdate)); // Format given String to new pattern

    // outputs: Jun 01,2013 12:53:10

Instead of using config files you can use a configuration database with a scoped systemConfig table and add all your settings there.

CREATE TABLE [dbo].[SystemConfig]  
    (  
      [Id] [int] IDENTITY(1, 1)  
                 NOT NULL ,  
      [AppName] [varchar](128) NULL ,  
      [ScopeName] [varchar](128) NOT NULL ,  
      [Key] [varchar](256) NOT NULL ,  
      [Value] [varchar](MAX) NOT NULL ,  
      CONSTRAINT [PK_SystemConfig_ID] PRIMARY KEY NONCLUSTERED ( [Id] ASC )  
        WITH ( PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF,  
               IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON,  
               ALLOW_PAGE_LOCKS = ON ) ON [PRIMARY]  
    )  
ON  [PRIMARY]  

GO  

SET ANSI_PADDING OFF  
GO  

ALTER TABLE [dbo].[SystemConfig] ADD  CONSTRAINT [DF_SystemConfig_ScopeName]  DEFAULT ('SystemConfig') FOR [ScopeName]  
GO 

With such configuration table you can create rows like such:

Then from your your application dal(s) wrapping EF you can easily retrieve the scoped configuration.
If you are not using dal(s) and working in the wire directly with EF, you can make an Entity from the SystemConfig table and use the value depending on the application you are on.

We developed an iPad app with XCode 4.2.1 and wanted to integrate the build into our continuous integration (Jenkins) for OTA distribution. Here's the solution I came up with:

# Unlock keychain
security unlock-keychain -p jenkins /Users/jenkins/Library/Keychains/login.keychain

# Build and sign app
xcodebuild -configuration Distribution clean build

# Set variables
APP_PATH="$PWD/build/Distribution-iphoneos/iPadApp.app"
VERSION=`defaults read $APP_PATH/Info CFBundleShortVersionString`
REVISION=`defaults read $APP_PATH/Info CFBundleVersion`
DATE=`date +"%Y%m%d-%H%M%S"`
ITUNES_LINK="<a href=\"itms-services:\/\/?action=download-manifest\&url=https:\/\/xxx.xxx.xxx\/iPadApp-$VERSION.$REVISION-$DATE.plist\">Download iPad2-App v$VERSION.$REVISION-$DATE<\/a>"

# Package and verify app
xcrun -sdk iphoneos PackageApplication -v build/Distribution-iphoneos/iPadApp.app -o $PWD/iPadApp-$VERSION.$REVISION-$DATE.ipa

# Create plist
cat iPadApp.plist.template | sed -e "s/\${VERSION}/$VERSION/" -e "s/\${DATE}/$DATE/" -e "s/\${REVISION}/$REVISION/" > iPadApp-$VERSION.$REVISION-$DATE.plist

# Update index.html
curl https://xxx.xxx.xxx/index.html -o index.html.$DATE
cat index.html.$DATE | sed -n '1h;1!H;${;g;s/\(<h3>Aktuelle Version<\/h3>\)\(.*\)\(<h3>&Auml;ltere Versionen<\/h3>.<ul>.<li>\)/\1\
${ITUNES_LINK}\
\3\2<\/li>\
<li>/g;p;}' | sed -e "s/\${ITUNES_LINK}/$ITUNES_LINK/" > index.html

Then Jenkins uploads the ipa, plist and html files to our webserver.

This is the plist template:

To set this up, you have to import the distribution certificate and provisioning profile into the designated user's keychain.

This works:

<img src="invalid_link"
     onerror="this.onerror=null;this.src='https://placeimg.com/200/300/animals';"

Live demo: http://jsfiddle.net/oLqfxjoz/

As Nikola pointed out in the comment below, in case the backup URL is invalid as well, some browsers will trigger the "error" event again which will result in an infinite loop. We can guard against this by simply nullifying the "error" handler via this.onerror=null;.

Use

if (Build.VERSION.SDK_INT >= 19) {
        mWebView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
    }

It should solve the error.

If you had generate a SSH-key with passphrase and then you forget your passphrase for this SSH-key,there's no way to recover it, You'll need to generate a brand new SSH keypair or switch to HTTPS cloning so you can use your GitHub password instead.

BUT,there are exceptions

If you configured your SSH passphrase with the OS X Keychain, you may be able to recover it.

1. In Finder, search for the Keychain Access app.
2. In Keychain Access, search for SSH.
3. Double click on the entry for your SSH key to open a new dialog box.

This can become kind of a serious issue if you're using a JS framework with hashbang (/#!/) URLs, e.g. Angular. Indeed, Angular will consider URLs with a non-hashbang fragment as invalid and throw an error :

Error: Invalid url "http://example.com/#_=_", missing hash prefix "#!".

If you're in such a case (and redirecting to your domain root), instead of doing :

window.location.hash = ''; // goes to /#, which is no better

Simply do :

window.location.hash = '!'; // goes to /#!, which allows Angular to take care of the rest

Best way is to Use a Python Web Frame Work you can choose Django/Flask. I will suggest you to Use Django because it's more powerful. Here is Step by guide to get complete your task :

pip install django
django-admin createproject buttonpython

then you have to create a file name views.py in buttonpython directory.

write below code in views.py:

from django.http import HttpResponse

def sample(request):
    #your python script code
    output=code output
    return HttpResponse(output)

Once done navigate to urls.py and add this stanza

from . import views

path('', include('blog.urls')),

Now go to parent directory and execute manage.py

python manage.py runserver 127.0.0.1:8001

If above answers don't work maybe you didn't add return value into getItem method in the custom adapter see this question and check out first answer.

To have code which looks like this:

List<Item> items;
...
for (Item item : In.reverse(items))
{
    ...
}

Put this code into a file called "In.java":

import java.util.*;

public enum In {;
    public static final <T> Iterable<T> reverse(final List<T> list) {
        return new ListReverseIterable<T>(list);
    }

    class ListReverseIterable<T> implements Iterable<T> {
        private final List<T> mList;

        public ListReverseIterable(final List<T> list) {
            mList = list;
        }

        public Iterator<T> iterator() {
            return new Iterator<T>() {
                final ListIterator<T> it = mList.listIterator(mList.size());

                public boolean hasNext() {
                    return it.hasPrevious();
                }
                public T next() {
                    return it.previous();
                }
                public void remove() {
                    it.remove();
                }
            };
        }
    }
}

If you already installed in your eclipse you can solve this problem below,

Go to Windows -> Install New Software and find your android plugin address

Check all lists and re-install your android plugin for eclipse

I solved it like this

For amazon linux(AMI):

sudo yum install nodejs npm --enablerepo=epel

USE:

 >>> a[[0,1,3]][:,[0,2]]
array([[ 0,  2],
   [ 4,  6],
   [12, 14]])

OR:

>>> a[[0,1,3],::2]
array([[ 0,  2],
   [ 4,  6],
   [12, 14]])

There are two parts to your question.

1) How to focus an input on page load?

You can just add the autofocus attribute to the input.

<input id="myinputbox" type="text" autofocus>

However, this might not be supported in all browsers, so we can use javascript.

window.onload = function() {
  var input = document.getElementById("myinputbox").focus();
}

2) How to place cursor at the end of the input text?

Here's a non-jQuery solution with some borrowed code from another SO answer.

function placeCursorAtEnd() {
  if (this.setSelectionRange) {
    // Double the length because Opera is inconsistent about 
    // whether a carriage return is one character or two.
    var len = this.value.length * 2;
    this.setSelectionRange(len, len);
  } else {
    // This might work for browsers without setSelectionRange support.
    this.value = this.value;
  }

  if (this.nodeName === "TEXTAREA") {
    // This will scroll a textarea to the bottom if needed
    this.scrollTop = 999999;
  }
};

window.onload = function() {
  var input = document.getElementById("myinputbox");

  if (obj.addEventListener) {
    obj.addEventListener("focus", placeCursorAtEnd, false);
  } else if (obj.attachEvent) {
    obj.attachEvent('onfocus', placeCursorAtEnd);
  }

  input.focus();
}

Here's an example of how I would accomplish this with jQuery.

<input type="text" autofocus>

<script>
$(function() {
  $("[autofocus]").on("focus", function() {
    if (this.setSelectionRange) {
      var len = this.value.length * 2;
      this.setSelectionRange(len, len);
    } else {
      this.value = this.value;
    }
    this.scrollTop = 999999;
  }).focus();
});
</script>

Try adding a button on mdi parent and add this code' to set your mdi child inside the mdi parent. change the yourchildformname to your MDI Child's form name and see if this works.

    Dim NewMDIChild As New yourchildformname()
    'Set the Parent Form of the Child window.
    NewMDIChild.MdiParent = Me
    'Display the new form.
    NewMDIChild.Show()

I'd do:

not any((x[i] != x[i+1] for i in range(0, len(x)-1)))

as any stops searching the iterable as soon as it finds a True condition.

I was given this as an interview question once, I suspect this has happened to you and you are coming here for help. Break the problem into three questions and it becomes easier.

1. how do you determine the next valid route
2. how do you determine if a point has been used
3. how do you avoid crossing over the same point again

Problem 1) Use the iterator pattern to provide a way of iterating route results. A good place to put the logic to get the next route is probably the "moveNext" of your iterator. To find a valid route, it depends on your data structure. For me it was a sql table full of valid route possibilities so I had to build a query to get the valid destinations given a source.

Problem 2) Push each node as you find them into a collection as you get them, this means that you can see if you are "doubling back" over a point very easily by interrogating the collection you are building on the fly.

Problem 3) If at any point you see you are doubling back, you can pop things off the collection and "back up". Then from that point try to "move forward" again.

Hack: if you are using Sql Server 2008 there is are some new "hierarchy" things you can use to quickly solve this if you structure your data in a tree.

<script type="text/javascript">var s = '/Controller/Action#11112';if(typeof s == 'string' && /\?*/.test(s)){s = s.replace(/\#.*/gi,'');}document.write(s);</script>

It's more common answer. And can be use with s= document.location.href;

That doesn't look like a very Angular way of doing it. I'm not entirely sure why it doesn't work, but you'd probably need to access the scope in order to use a function like that.

My suggestion would be to create a filter. That's the Angular way.

myModule.filter('ceil', function() {
    return function(input) {
        return Math.ceil(input);
    };
});

Then in your HTML do this:

<p>The percentage is {{ (100*count/total) | ceil }}%</p>

I know this is an old post, probably no one would scroll this far, I know I didn't. So, after hours of trying different stuff, I found this blog and dude killed it. Simplest way to do this, tried it and it works like a charm.

Blog

In the ViewModel:

...

public bool CanClose { get; set; }

private RelayCommand closeCommand;
public ICommand CloseCommand
{
    get
    {
        if(closeCommand == null)
        (
            closeCommand = new RelayCommand(param => Close(), param => CanClose);
        )
    }
}

public void Close()
{
    this.Close();
}

...

add an Action property to the ViewModel, but define it from the View’s code-behind file. This will let us dynamically define a reference on the ViewModel that points to the View.

On the ViewModel, we’ll simply add:

public Action CloseAction { get; set; }

And on the View, we’ll define it as such:

public View()
{
    InitializeComponent() // this draws the View
    ViewModel vm = new ViewModel(); // this creates an instance of the ViewModel
    this.DataContext = vm; // this sets the newly created ViewModel as the DataContext for the View
    if ( vm.CloseAction == null )
        vm.CloseAction = new Action(() => this.Close());
}

You can put it like this

  assertTrue("your fail message ",Long.parseLong(previousTokenValues[1]) > Long.parseLong(currentTokenValues[1]));

I kept having this problem because windows was setting my node_modules folder to Readonly. Make sure you uncheck this.

It's probably easiest to create your query object directly as:

  Test.find({
      $and: [
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ]
  }, function (err, results) {
      ...
  }

But you can also use the Query#and helper that's available in recent 3.x Mongoose releases:

  Test.find()
      .and([
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ])
      .exec(function (err, results) {
          ...
      });

Like many people I've been digging the net with no real answer :(

I've nevertheless find out a bypass that could help others. In my case I fully control my web server. In fact it is part of my application (see end reference). It is easy for me to add a script to my http response. I modified my httpd server to inject a small script within every html pages. I only push a extra 'js script' line right after my header construction, that set an existing variable from my document within my browser [I choose location], but any other option is possible. While my server is written in nodejs, I've no doubt that the same technique can be use from PHP or others.

  case ".html":
    response.setHeader("Content-Type", "text/html");
    response.write ("<script>location['GPSD_HTTP_AJAX']=true</script>")
    // process the real contend of my page

Now every html pages loaded from my server, have this script executed by the browser at reception. I can then easily check from JavaScript if the variable exist or not. In my usecase I need to know if I should use JSON or JSON-P profile to avoid CORS issue, but the same technique can be used for other purposes [ie: choose in between development/production server, get from server a REST/API key, etc ....]

On the browser you just need to check variable directly from JavaScript as in my example, where I use it to select my Json/JQuery profile

 // Select direct Ajax/Json profile if using GpsdTracking/HttpAjax server otherwise use JsonP
  var corsbypass = true;  
  if (location['GPSD_HTTP_AJAX']) corsbypass = false;

  if (corsbypass) { // Json & html served from two different web servers
    var gpsdApi = "http://localhost:4080/geojson.rest?jsoncallback=?";
  } else { // Json & html served from same web server [no ?jsoncallback=]
    var gpsdApi = "geojson.rest?";
  }
  var gpsdRqt = 
      {key   :123456789 // user authentication key
      ,cmd   :'list'    // rest command
      ,group :'all'     // group to retreive
      ,round : true     // ask server to round numbers
   };
   $.getJSON(gpsdApi,gpsdRqt, DevListCB);

For who ever would like to check my code: https://www.npmjs.org/package/gpsdtracking

try

.insertAfter()

here

$(content).insertAfter('#bla');

You can also use flexbox, but you'd have to add a parent div that covers div#top and div#term-defs. So the HTML looks like this:

    #content {_x000D_
        width: 100%;_x000D_
        height: 100%;_x000D_
        display: flex;_x000D_
        flex-direction: column;_x000D_
    }_x000D_
_x000D_
    #term-defs {_x000D_
        flex-grow: 1;_x000D_
        overflow: auto;_x000D_
    } 

    <body>_x000D_
        <div id="content">_x000D_
            <div id="top">_x000D_
                <a href="#A">A</a> |_x000D_
                <a href="#B">B</a> |_x000D_
                <a href="#Z">Z</a>_x000D_
            </div>_x000D_
    _x000D_
            <div id="term-defs">_x000D_
                <dl>_x000D_
                    <span id="A"></span>_x000D_
                    <dt>foo</dt>_x000D_
                    <dd>This is the sound made by a fool</dd>_x000D_
                    <!-- and so on ... -->_x000D_
                </dl>_x000D_
            </div>_x000D_
        </div>_x000D_
    </body>

flex-grow ensures that the div's size is equal to the remaining size.

You could do the same without flexbox, but it would be more complicated to work out the height of #term-defs (you'd have to know the height of #top and use calc(100% - 999px) or set the height of #term-defs directly).
With flexbox dynamic sizes of the divs are possible.

One difference is that the scrollbar only appears on the term-defs div.

in your css:

.selected{
    background: #F00;
}

in the jquery:

$("#data tr").click(function(){
   $(this).toggleClass('selected');
});

Basically you create a class and adds/removes it from the selected row.

Btw you could have shown more effort, there's no css or jquery/js at all in your code xD

/stop([a-zA-Z])+/

Will match any stop word (stop, stopped, stopping, etc)

However, if you just want to match "stop" at the start of a string

/^stop/

will do :D

<input id="name" data-upper type="text"/>
<input id="middle" data-upper type="text"/>
<input id="sur" data-upper type="text"/>

Upper the text on dynamically created element which has attribute upper and when keyup action happens

$(document.body).on('keyup', '[data-upper]', function toUpper() {
  this.value = this.value.toUpperCase();
});

The best solution I've found for this is to contain them in a parent div, and give that div a font-size of 0.

Just to enhance @adivis12 answer, you don't need to do the if statement. Put it like this:

fig, ax = plt.subplots()
for BAR in dict_of_dfs.keys():
    dict_of_dfs[BAR].plot(ax=ax)

You should use the unslick method:

function getSliderSettings(){
  return {
    infinite: true,
    slidesToShow: 3,
    slidesToScroll: 1
  }
}

$.ajax({
  type: 'get',
  url: '/public/index',
  dataType: 'script',
  data: data_send,
  success: function() {
    $('.skills_section').slick('unslick'); /* ONLY remove the classes and handlers added on initialize */
    $('.my-slide').remove(); /* Remove current slides elements, in case that you want to show new slides. */
    $('.skills_section').slick(getSliderSettings()); /* Initialize the slick again */
  }
});

Why not try catch, like this:

protected void onPostExecute(Object result) {
        try {
            if ((mDialog != null) && mDialog.isShowing()) {
                mDialog.dismiss();
            }
        } catch (Exception ex) {
            Log.e(TAG, ex.getMessage(), ex);
        }
    }

For multiple checkbox with same name... Code to remove unnecessary false :

List<string> d_taxe1 = new List<string>(Request.Form.GetValues("taxe1"));
d_taxe1 = form_checkbox.RemoveExtraFalseFromCheckbox(d_taxe1);

Function

public class form_checkbox
{

    public static List<string> RemoveExtraFalseFromCheckbox(List<string> val)
    {
        List<string> d_taxe1_list = new List<string>(val);

        int y = 0;

        foreach (string cbox in val)
        {

            if (val[y] == "false")
            {
                if (y > 0)
                {
                    if (val[y - 1] == "true")
                    {
                        d_taxe1_list[y] = "remove";
                    }
                }

            }

            y++;
        }

        val = new List<string>(d_taxe1_list);

        foreach (var del in d_taxe1_list)
            if (del == "remove") val.Remove(del);

        return val;

    }      



}

Use it :

int x = 0;
foreach (var detail in d_prix){
factured.taxe1 = (d_taxe1[x] == "true") ? true : false;
x++;
}

You can just use the return value of require:

if(!require(somepackage)){
    install.packages("somepackage")
    library(somepackage)
}

I use library after the install because it will throw an exception if the install wasn't successful or the package can't be loaded for some other reason. You make this more robust and reuseable:

dynamic_require <- function(package){
  if(eval(parse(text=paste("require(",package,")")))) return True

  install.packages(package)
  return eval(parse(text=paste("require(",package,")")))
}

The downside to this method is that you have to pass the package name in quotes, which you don't do for the real require.

In jQuery 1.6+ it's better to use:

$(selector).prop('href',"http://www...") to set the value, and

$(selector).prop('href') to get the value

In short, .prop gets and sets values on the DOM object, and .attr gets and sets values in the HTML. This makes .prop a little faster and possibly more reliable in some contexts.

For a vivid demonstration, the following monster is pretty good but still does not correctly recognize all syntactically valid email addresses: it recognizes nested comments up to four levels deep.

This is a job for a parser, but even if an address is syntactically valid, it still may not be deliverable. Sometimes you have to resort to the hillbilly method of "Hey, y'all, watch ee-us!"

Building on alko's answer that almost worked for me, except for the filtering step (where I get: ValueError: cannot reindex from a duplicate axis), here is the final solution I used:

# join the dataframes
united_data = pd.concat([data1, data2, data3, ...])
# group the data by the whole row to find duplicates
united_data_grouped = united_data.groupby(list(united_data.columns))
# detect the row indices of unique rows
uniq_data_idx = [x[0] for x in united_data_grouped.indices.values() if len(x) == 1]
# extract those unique values
uniq_data = united_data.iloc[uniq_data_idx]

Found a solution to this. Just ISNULL the CASE statement:

ISNULL(CASE x WHEN x THEN x ELSE x END, '') AS 'BLAH'

    public static void main(String[] args) {
        long a = 1111;
        Long b = 1113L;
        if(a == b.longValue())
    {
        System.out.println("Equals");
    }else{
        System.out.println("not equals");
    }
  }

or:

    public static void main(String[] args) {
        long a = 1111;
        Long b = 1113L;
        if(a == b)
    {
        System.out.println("Equals");
    }else{
        System.out.println("not equals");
    }
  }

In new APIs don't forget about TAG:

notify(String tag, int id, Notification notification)

and correspondingly

cancel(String tag, int id) 

instead of:

cancel(int id)

if you are using netbeans you can add a jlabel to the frame and through properties change its icon to your image and remove the text. then move the jlabel to the bottom of the Jframe or any content pane through navigator

Nothing compares to extjs in terms of community size and presence on StackOverflow. Despite previous controversy, Ext JS now has a GPLv3 open source license. Its learning curve is long, but it can be quite rewarding once learned. Ext JS lacks a Material Design theme, and the team has repeatedly refused to release the source code on GitHub. For mobile, one must use the separate Sencha Touch library.

Have in mind also that,

large JavaScript libraries, such as YUI, have been receiving less attention from the community. Many developers today look at large JavaScript libraries as walled gardens they don’t want to be locked into.

-- Announcement of YUI development being ceased

That said, below are a number of Ext JS alternatives currently available.

Leading client widget libraries

1. Blueprint is a React-based UI toolkit developed by big data analytics company Palantir in TypeScript, and "optimized for building complex data-dense interfaces for desktop applications". Actively developed on GitHub as of May 2019, with comprehensive documentation. Components range from simple (chips, toast, icons) to complex (tree, data table, tag input with autocomplete, date range picker. No accordion or resizer.

   Blueprint targets modern browsers (Chrome, Firefox, Safari, IE 11, and Microsoft Edge) and is licensed under a modified Apache license.

   Sandbox / demo • GitHub • Docs

2. Webix - an advanced, easy to learn, mobile-friendly, responsive and rich free&open source JavaScript UI components library. Webix spun off from DHTMLX Touch (a project with 8 years of development behind it - see below) and went on to become a standalone UI components framework. The GPL3 edition allows commercial use and lets non-GPL applications using Webix keep their license, e.g. MIT, via a license exemption for FLOSS. Webix has 55 UI widgets, including trees, grids, treegrids and charts. Funding comes from a commercial edition with some advanced widgets (Pivot, Scheduler, Kanban, org chart etc.). Webix has an extensive list of free and commercial widgets, and integrates with most popular frameworks (React, Vue, Meteor, etc) and UI components.

   

   Skins look modern, and include a Material Design theme. The Touch theme also looks quite Material Design-ish. See also the Skin Builder.

   Minimal GitHub presence, but includes the library code, and the documentation (which still needs major improvements). Webix suffers from a having a small team and a lack of marketing. However, they have been responsive to user feedback, both on GitHub and on their forum.

   The library was lean (128Kb gzip+minified for all 55 widgets as of ~2015), faster than ExtJS, dojo and others, and the design is pleasant-looking. The current version of Webix (v6, as of Nov 2018) got heavier (400 - 676kB minified but NOT gzipped).

   The demos on Webix.com look and function great. The developer, XB Software, uses Webix in solutions they build for paying customers, so there's likely a good, funded future ahead of it.

   Webix aims for backwards compatibility down to IE8, and as a result carries some technical debt.

3. react-md - MIT-licensed Material Design UI components library for React. Responsive, accessible. Implements components from simple (buttons, cards) to complex (sortable tables, autocomplete, tags input, calendars). One lead author, ~1900 GitHub stars.

4. kendo - jQuery-based UI toolkit with 40+ basic open-source widgets, plus commercial professional widgets (grids, trees, charts etc.). Responsive&mobile support. Works with Bootstrap and AngularJS. Modern, with Material Design themes. The documentation is available on GitHub, which has enabled numerous contributions from users (4500+ commits, 500+ PRs as of Jan 2015).

   

   Well-supported commercially, claiming millions of developers, and part of a large family of developer tools. Telerik has received many accolades, is a multi-national company (Bulgaria, US), was acquired by Progress Software, and is a thought leader.

   A Kendo UI Professional developer license costs $700 and posting access to most forums is conditioned upon having a license or being in the trial period.

   [Wikipedia] • GitHub/Telerik • Demos • Playground • Tools

5. OpenUI5 - jQuery-based UI framework with 180 widgets, Apache 2.0-licensed and fully-open sourced and funded by German software giant SAP SE.

   

   The community is much larger than that of Webix, SAP is hiring developers to grow OpenUI5, and they presented OpenUI5 at OSCON 2014.

   The desktop themes are rather lackluster, but the Fiori design for web and mobile looks clean and neat.

   Wikipedia • GitHub • Mobile-first controls demos • Desktop controls demos • SO

6. DHTMLX - JavaScript library for building rich Web and Mobile apps. Looks most like ExtJS - check the demos. Has been developed since 2005 but still looks modern. All components except TreeGrid are available under GPLv2 but advanced features for many components are only available in the commercial PRO edition - see for example the tree. Claims to be used by many Fortune 500 companies.

   

   Minimal presence on GitHub (the main library code is missing) and StackOverflow but active forum. The documentation is not available on GitHub, which makes it difficult to improve by the community.

7. Polymer, a Web Components polyfill, plus Polymer Paper, Google's implementation of the Material design. Aimed at web and mobile apps. Doesn't have advanced widgets like trees or even grids but the controls it provides are mobile-first and responsive. Used by many big players, e.g. IBM or USA Today.

   

8. Ant Design claims it is "a design language for background applications", influenced by "nature" and helping designers "create low-entropy atmosphere for developer team". That's probably a poor translation from Chinese for "UI components for enterprise web applications". It's a React UI library written in TypeScript, with many components, from simple (buttons, cards) to advanced (autocomplete, calendar, tag input, table).

   The project was born in China, is popular with Chinese companies, and parts of the documentation are available only in Chinese. Quite popular on GitHub, yet it makes the mistake of splitting the community into Chinese and English chat rooms. The design looks Material-ish, but fonts are small and the information looks lost in a see of whitespace.

9. PrimeUI - collection of 45+ rich widgets based on jQuery UI. Apache 2.0 license. Small GitHub community. 35 premium themes available.

10. qooxdoo - "a universal JavaScript framework with a coherent set of individual components", developed and funded by German hosting provider 1&1 (see the contributors, one of the world's largest hosting companies. GPL/EPL (a business-friendly license).

    Mobile themes look modern but desktop themes look old (gradients).

11. jQuery UI - easy to pick up; looks a bit dated; lacks advanced widgets. Of course, you can combine it with independent widgets for particular needs, e.g. trees or other UI components, but the same can be said for any other framework.

12. angular + Angular UI. While Angular is backed by Google, it's being radically revamped in the upcoming 2.0 version, and "users will need to get to grips with a new kind of architecture. It's also been confirmed that there will be no migration path from Angular 1.X to 2.0". Moreover, the consensus seems to be that Angular 2 won't really be ready for use until a year or two from now. Angular UI has relatively few widgets (no trees, for example).

13. DojoToolkit and their powerful Dijit set of widgets. Completely open-sourced and actively developed on GitHub, but development is now (Nov 2018) focused on the new dojo.io framework, which has very few basic widgets. BSD/AFL license. Development started in 2004 and the Dojo Foundation is being sponsored by IBM, Google, and others - see Wikipedia. 7500 questions here on SO.

    

    Themes look desktop-oriented and dated - see the theme tester in dijit. The official theme previewer is broken and only shows "Claro". A Bootstrap theme exists, which looks a lot like Bootstrap, but doesn't use Bootstrap classes. In Jan 2015, I started a thread on building a Material Design theme for Dojo, which got quite popular within the first hours. However, there are questions regarding building that theme for the current Dojo 1.10 vs. the next Dojo 2.0. The response to that thread shows an active and wide community, covering many time zones.

    Unfortunately, Dojo has fallen out of popularity and fewer companies appear to use it, despite having (had?) a strong foothold in the enterprise world. In 2009-2012, its learning curve was steep and the documentation needed improvements; while the documentation has substantially improved, it's unclear how easy it is to pick up Dojo nowadays.

    With a Material Design theme, Dojo (2.0?) might be the killer UI components framework.

14. Enyo - front-end library aimed at mobile and TV apps (e.g. large touch-friendly controls). Developed by LG Electronix and Apache-licensed on GitHub.

15. The radical Cappuccino - Objective-J (a superset of JavaScript) instead of HTML+CSS+DOM

16. Mochaui, MooTools UI Library User Interface Library. <300 GitHub stars.

17. CrossUI - cross-browser JS framework to develop and package the exactly same code and UI into Web Apps, Native Desktop Apps (Windows, OS X, Linux) and Mobile Apps (iOS, Android, Windows Phone, BlackBerry). Open sourced LGPL3. Featured RAD tool (form builder etc.). The UI looks desktop-, not web-oriented. Actively developed, small community. No presence on GitHub.

18. ZinoUI - simple widgets. The DataTable, for instance, doesn't even support sorting.

19. Wijmo - good-looking commercial widgets, with old (jQuery UI) widgets open-sourced on GitHub (their development stopped in 2013). Developed by ComponentOne, a division of GrapeCity. See Wijmo Complete vs. Open.

20. CxJS - commercial JS framework based on React, Babel and webpack offering form elements, form validation, advanced grid control, navigational elements, tooltips, overlays, charts, routing, layout support, themes, culture dependent formatting and more.

Widgets - Demo Apps - Examples - GitHub

Full-stack frameworks

1. SproutCore - developed by Apple for web applications with native performance, handling large data sets on the client. Powers iCloud.com. Not intended for widgets.

2. Wakanda: aimed at business/enterprise web apps - see What is Wakanda?. Architecture:

   • Wakanda Server (server-side JavaScript (custom engine) + open-source NoSQL database)
   • desktop IDE and WYSIWYG editor for tables, forms, reports

   • Wakanda Application Framework (datasource layer + browser-based interface widgets) that helps with browser and device compatibility across desktop and mobile

     Wakanda is highly integrated, includes a ton of features out of the box, but has a very small GitHub community and SO presence.

3. Servoy - "a cross platform frontend development and deployment environment for SQL databases". Boasts a "full WYSIWIG (What You See Is What You Get) UI designer for HTML5 with built-in data-binding to back-end services", responsive design, support for HTML6 Web Components, Websockets and mobile platforms. Written in Java and generates JavaScript code using various JavaBeans.

4. SmartClient/SmartGWT - mobile and cross-browser HTML5 UI components combined with a Java server. Aimed at building powerful business apps - see demos.

5. Vaadin - full-stack Java/GWT + JavaScript/HTML3 web app framework

6. Backbase - portal software

7. Shiny - front-end library on top R, with visualization, layout and control widgets

8. ZKOSS: Java+jQuery+Bootstrap framework for building enterprise web and mobile apps.

CSS libraries + minimal widgets

These libraries don't implement complex widgets such as tables with sorting/filtering, autocompletes, or trees.

1. Bootstrap

2. Foundation for Apps - responsive front-end framework on top of AngularJS; more of a grid/layout/navigation library

3. UI Kit - similar to Bootstrap, with fewer widgets, but with official off-canvas.

Libraries using HTML Canvas

Using the canvas elements allows for complete control over the UI, and great cross-browser compatibility, but comes at the cost of missing native browser functionality, e.g. page search via Ctrl/Cmd+F.

1. Zebra - demos

No longer developed as of Dec 2014

1. Yahoo! User Interface - YUI, launched in 2005, but no longer maintained by the core contributors - see the announcement, which highlights reasons why large UI widget libraries are perceived as walled gardens that developers don't want to be locked into.
2. echo3, GitHub. Supports writing either server-side Java applications that don't require developer knowledge of HTML, HTTP, or JavaScript, or client-side JavaScript-based applications do not require a server, but can communicate with one via AJAX. Last update: July 2013.
3. ampleSDK
4. Simpler widgets livepipe.net
5. JxLib

I can understand your pain. In my case the error got resolved by performing below steps:

1. Start > Run > dcomcnfg.
2. Open the folder DCOM Config and Select Component Services > Computers > My Computer > DCOM Config.
3. Select “Microsoft Office Word 97 – 2003 document”/”Microsoft Excel Application” and go to its properties.
4. In "Security" tab set “Launch and Activation Permissions” need to be Customize (Authorized user).
5. Now go to IIS and select application pool of the Web and go to its Advanced Settings and select “NETWORK SERVICE” as identity user.

Hope this helps.

You can further modify the hput()/hget() interface so that you have named hashes as follows:

hput() {
    eval "$1""$2"='$3'
}

hget() {
    eval echo '${'"$1$2"'#hash}'
}

and then

hput capitals France Paris
hput capitals Netherlands Amsterdam
hput capitals Spain Madrid
echo `hget capitals France` and `hget capitals Netherlands` and `hget capitals Spain`

This lets you define other maps that don't conflict (e.g., 'rcapitals' which does country lookup by capital city). But, either way, I think you'll find that this is all pretty terrible, performance-wise.

If you really want fast hash lookup, there's a terrible, terrible hack that actually works really well. It is this: write your key/values out to a temporary file, one-per line, then use 'grep "^$key"' to get them out, using pipes with cut or awk or sed or whatever to retrieve the values.

Like I said, it sounds terrible, and it sounds like it ought to be slow and do all sorts of unnecessary IO, but in practice it is very fast (disk cache is awesome, ain't it?), even for very large hash tables. You have to enforce key uniqueness yourself, etc. Even if you only have a few hundred entries, the output file/grep combo is going to be quite a bit faster - in my experience several times faster. It also eats less memory.

Here's one way to do it:

hinit() {
    rm -f /tmp/hashmap.$1
}

hput() {
    echo "$2 $3" >> /tmp/hashmap.$1
}

hget() {
    grep "^$2 " /tmp/hashmap.$1 | awk '{ print $2 };'
}

hinit capitals
hput capitals France Paris
hput capitals Netherlands Amsterdam
hput capitals Spain Madrid

echo `hget capitals France` and `hget capitals Netherlands` and `hget capitals Spain`

The for each syntax is supported as an extension to native c++ in Visual Studio.

The example provided in msdn

#include <vector>
#include <iostream>

using namespace std;

int main() 
{
  int total = 0;

  vector<int> v(6);
  v[0] = 10; v[1] = 20; v[2] = 30;
  v[3] = 40; v[4] = 50; v[5] = 60;

  for each(int i in v) {
    total += i;
  }

  cout << total << endl;
}

(works in VS2013) is not portable/cross platform but gives you an idea of how to use for each.

The standard alternatives (provided in the rest of the answers) apply everywhere. And it would be best to use those.

Somthing like this should workL

SELECT BookingId, StartTime
FROM Booking
WHERE StartTime between dateadd(hour, -1, getdate()) and getdate()

Maybe a bit simpler approach with ngInit and Lodash's debounce method without the need of custom directive:

Controller:

$scope.items = [1, 2, 3, 4];

$scope.refresh = _.debounce(function() {
    // Debounce has timeout and prevents multiple calls, so this will be called 
    // once the iteration finishes
    console.log('we are done');
}, 0);

Template:

<ul>
    <li ng-repeat="item in items" ng-init="refresh()">{{item}}</li>
</ul>

Update

There is even simpler pure AngularJS solution using ternary operator:

Template:

<ul>
    <li ng-repeat="item in items" ng-init="$last ? doSomething() : null">{{item}}</li>
</ul>

Be aware that ngInit uses pre-link compilation phase - i.e. the expression is invoked before child directives are processed. This means that still an asynchronous processing might be required.

Just to put my two cents in, if you wanted an object containing all the requests

function getRequests() {
    var s1 = location.search.substring(1, location.search.length).split('&'),
        r = {}, s2, i;
    for (i = 0; i < s1.length; i += 1) {
        s2 = s1[i].split('=');
        r[decodeURIComponent(s2[0]).toLowerCase()] = decodeURIComponent(s2[1]);
    }
    return r;
};

var QueryString = getRequests();

//if url === "index.html?test1=t1&test2=t2&test3=t3"
console.log(QueryString["test1"]); //logs t1
console.log(QueryString["test2"]); //logs t2
console.log(QueryString["test3"]); //logs t3

Note, the key for each get param is set to lower case. So, I made a helper function. So now it's case-insensitive.

function Request(name){
    return QueryString[name.toLowerCase()];
}

These will also redirect both:

yourcommand  &> /dev/null

yourcommand  >& /dev/null

though the bash manual says the first is preferred.

There is no such syntax in SQL Server, though CREATE TABLE AS ... SELECT does exist in PDW. In SQL Server you can use this query to create an empty table:

SELECT * INTO schema.newtable FROM schema.oldtable WHERE 1 = 0;

(If you want to make a copy of the table including all of the data, then leave out the WHERE clause.)

Note that this creates the same column structure (including an IDENTITY column if one exists) but it does not copy any indexes, constraints, triggers, etc.

Pass a returnUrl parameter (url encoded) to the change and login actions and inside redirect to this given returnUrl. Your login action might look something like this:

public ActionResult Login(string returnUrl) 
{
    // Do something...
    return Redirect(returnUrl);
}

As an alternative option you could install OpenSSH http://www.mls-software.com/opensshd.html and then simply ssh user@host -pw password -m command_run

Edit: After a response from user2687375 when installing, select client only. Once this is done you should be able to initiate SSH from command.

Then you can create an ssh batch script such as

ECHO OFF
CLS
:MENU
ECHO.
ECHO ........................
ECHO SSH servers
ECHO ........................
ECHO.
ECHO 1 - Web Server 1
ECHO 2 - Web Server 2
ECHO E - EXIT
ECHO.

SET /P M=Type 1 - 2 then press ENTER:
IF %M%==1 GOTO WEB1
IF %M%==2 GOTO WEB2
IF %M%==E GOTO EOF

REM ------------------------------
REM SSH Server details
REM ------------------------------

:WEB1
CLS
call ssh [email protected]
cmd /k

:WEB2
CLS
call ssh [email protected]
cmd /k

They say IE has issues with the input event but other than that, the solution is rather straightforward.

ta = document.querySelector("textarea");_x000D_
count = document.querySelector("label");_x000D_
_x000D_
ta.addEventListener("input", function (e) {_x000D_
  count.innerHTML = this.value.length;_x000D_
});

<textarea id="my-textarea" rows="4" cols="50" maxlength="10">_x000D_
</textarea>_x000D_
<label for="my-textarea"></label>

If using a where clause be sure to include .First() if you do not want a IQueryable object.

I think this is what you are looking for

 <asp:TextBox ID="txbPass" runat="server" TextMode="Password"></asp:TextBox>

If you don't specify the random_state in your code, then every time you run(execute) your code a new random value is generated and the train and test datasets would have different values each time.

However, if a fixed value is assigned like random_state = 42 then no matter how many times you execute your code the result would be the same .i.e, same values in train and test datasets.

If your $VARIABLE is a string containing spaces or other special characters, and single square brackets are used (which is a shortcut for the test command), then the string may be split out into multiple words. Each of these is treated as a separate argument.

So that one variable is split out into many arguments:

VARIABLE=$(/some/command);  
# returns "hello world"

if [ $VARIABLE == 0 ]; then
  # fails as if you wrote:
  # if [ hello world == 0 ]
fi 

The same will be true for any function call that puts down a string containing spaces or other special characters.

Easy fix

Wrap the variable output in double quotes, forcing it to stay as one string (therefore one argument). For example,

VARIABLE=$(/some/command);
if [ "$VARIABLE" == 0 ]; then
  # some action
fi 

Simple as that. But skip to "Also beware..." below if you also can't guarantee your variable won't be an empty string, or a string that contains nothing but whitespace.

Or, an alternate fix is to use double square brackets (which is a shortcut for the new test command).

This exists only in bash (and apparently korn and zsh) however, and so may not be compatible with default shells called by /bin/sh etc.

This means on some systems, it might work from the console but not when called elsewhere, like from cron, depending on how everything is configured.

It would look like this:

VARIABLE=$(/some/command);
if [[ $VARIABLE == 0 ]]; then
  # some action
fi 

If your command contains double square brackets like this and you get errors in logs but it works from the console, try swapping out the [[ for an alternative suggested here, or, ensure that whatever runs your script uses a shell that supports [[ aka new test.

Also beware of the [: unary operator expected error

If you're seeing the "too many arguments" error, chances are you're getting a string from a function with unpredictable output. If it's also possible to get an empty string (or all whitespace string), this would be treated as zero arguments even with the above "quick fix", and would fail with [: unary operator expected

It's the same 'gotcha' if you're used to other languages - you don't expect the contents of a variable to be effectively printed into the code like this before it is evaluated.

Here's an example that prevents both the [: too many arguments and the [: unary operator expected errors: replacing the output with a default value if it is empty (in this example, 0), with double quotes wrapped around the whole thing:

VARIABLE=$(/some/command);
if [ "${VARIABLE:-0}" == 0 ]; then
  # some action
fi 

(here, the action will happen if $VARIABLE is 0, or empty. Naturally, you should change the 0 (the default value) to a different default value if different behaviour is wanted)

Final note: Since [ is a shortcut for test, all the above is also true for the error test: too many arguments (and also test: unary operator expected)

For those trying to install Redmine, I missed sudo apt-get install ruby-all-dev after trying all of the above.

Initial error being mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h.

No. Most YouTube videos only have one pre-generated "poster" thumbnail (480x360). They usually have several other lower resolution thumbnails (120x90). So even if there were an embedding parameter to use an alternate poster image (which there isn't), it's result wouldn't be acceptable.

You can theoretically use the Player API to seek the video to whatever location you want, but this would be a major hack for a minor result.

You can achieve with following way

    this.projectService.create(project)
    .subscribe(
        result => {
         console.log(result);
        },
        error => {
            console.log(error);
            this.errors = error
        }
    ); 
}

if (!this.errors) {
    //route to new page
}

Codeigniter is an MVC (Model - View - Controller) framework. It's really not a good idea to call a function from the view. The view should be used just for presentation, and all your logic should be happening before you get to the view in the controllers and models.

A good start for clarifying the best practice is to follow this tutorial:

https://codeigniter.com/user_guide/tutorial/index.html

It's simple, but it really lays out an excellent how-to.

I hope this helps!

This was killing me as I had the same issue. I just going over old projects. Really redoing old lessons from class to get more practice. The repos just have compatibility issues. So I import the project. Then add the source like others state. Then close the project. Delete the .idea directory in the root and re-import project.

This script will add a div that covers the entire window as the page loads. It will show a CSS-only loading spinner automatically. It will wait until the window (not the document) finishes loading, then it will wait an optional extra few seconds.

• Works with jQuery 3 (it has a new window load event)
• No image needed but it's easy to add one
• Change the delay for more branding or instructions
• Only dependency is jQuery.

This is easier to do if you convert your matrix to a data frame using as.data.frame(). In that case the previous answers (using subset or m$three) will work, otherwise they will not.

To perform the operation on a matrix, you can define a column by name:

m[m[, "three"] == 11,]

Or by number:

m[m[,3] == 11,]

Note that if only one row matches, the result is an integer vector, not a matrix.

You can use string.scan(your_regex).flatten. If your regex contains groups, it will return in a single plain array.

string = "A 54mpl3 string w1th 7 numbers scatter3r ar0und"
your_regex = /(\d+)[m-t]/
string.scan(your_regex).flatten
=> ["54", "1", "3"]

Regex can be a named group as well.

string = 'group_photo.jpg'
regex = /\A(?<name>.*)\.(?<ext>.*)\z/
string.scan(regex).flatten

You can also use gsub, it's just one more way if you want MatchData.

str.gsub(/\d/).map{ Regexp.last_match }

Just came across this question, and wanted to suggest an alternate approach.

In the markup the OP provided, there is a click event binding. This makes me think that the elements are being used as "buttons". If that is the case, they could be marked up as <button> elements and styled like links, if that is the look you desire. (For example, Bootstrap has a built-in "link" button style, https://v4-alpha.getbootstrap.com/components/buttons/#examples)

This has several direct and indirect benefits. It allows you to bind to the disabled property, which when set will disable mouse and keyboard events automatically. It lets you style the disabled state based on the disabled attribute, so you don't have to also manipulate the element's class. It is also better for accessibility.

For a good write-up about when to use buttons and when to use links, see Links are not buttons. Neither are DIVs and SPANs

Here is new path for changing iOS simulator you just need to change

default: 'iPhone 6' or something else 

Path:

<project_root>/node_modules/@react-native-community/cli/build/commands/runIOS/runIOS.js

A simple solution would be doing something like this:

mysqldump -u myuser --no-create-info --extended-insert=FALSE databasename | grep -i "<search string>"

According the to Windows Dev Center WIN32_LEAN_AND_MEAN excludes APIs such as Cryptography, DDE, RPC, Shell, and Windows Sockets.

The trick is to implement a stable sort. I've created a Widget class that can contain your test data:

public class Widget : IComparable
{
    int x;
    int y;
    public int X
    {
        get { return x; }
        set { x = value; }
    }

    public int Y
    {
        get { return y; }
        set { y = value; }
    }

    public Widget(int argx, int argy)
    {
        x = argx;
        y = argy;
    }

    public int CompareTo(object obj)
    {
        int result = 1;
        if (obj != null && obj is Widget)
        {
            Widget w = obj as Widget;
            result = this.X.CompareTo(w.X);
        }
        return result;
    }

    static public int Compare(Widget x, Widget y)
    {
        int result = 1;
        if (x != null && y != null)                
        {                
            result = x.CompareTo(y);
        }
        return result;
    }
}

I implemented IComparable, so it can be unstably sorted by List.Sort().

However, I also implemented the static method Compare, which can be passed as a delegate to a search method.

I borrowed this insertion sort method from C# 411:

 public static void InsertionSort<T>(IList<T> list, Comparison<T> comparison)
        {           
            int count = list.Count;
            for (int j = 1; j < count; j++)
            {
                T key = list[j];

                int i = j - 1;
                for (; i >= 0 && comparison(list[i], key) > 0; i--)
                {
                    list[i + 1] = list[i];
                }
                list[i + 1] = key;
            }
    }

You would put this in the sort helpers class that you mentioned in your question.

Now, to use it:

    static void Main(string[] args)
    {
        List<Widget> widgets = new List<Widget>();

        widgets.Add(new Widget(0, 1));
        widgets.Add(new Widget(1, 1));
        widgets.Add(new Widget(0, 2));
        widgets.Add(new Widget(1, 2));

        InsertionSort<Widget>(widgets, Widget.Compare);

        foreach (Widget w in widgets)
        {
            Console.WriteLine(w.X + ":" + w.Y);
        }
    }

And it outputs:

0:1
0:2
1:1
1:2
Press any key to continue . . .

This could probably be cleaned up with some anonymous delegates, but I'll leave that up to you.

EDIT: And NoBugz demonstrates the power of anonymous methods...so, consider mine more oldschool :P

Another alternative:

$('option:selected', $('#mySelectParent')).removeAttr("selected");

Hope it helps

By using the _MSC_VER macro.

There's a faster and easy way in Java 9 without involving much of code: Using Collection Factory methods:

List<String> list = List.of("first", "second", "third");

The following JavaScript will open a new browser window, 450px wide by 300px high with scrollbars:

window.open("http://myurl", "_blank", "scrollbars=1,resizable=1,height=300,width=450");

You can add this to a link like so:

<a href='#' onclick='javascript:window.open("http://myurl", "_blank", "scrollbars=1,resizable=1,height=300,width=450");' title='Pop Up'>Pop Up</a>

Use Collections.shuffle() twice, with two Random objects initialized with the same seed:

long seed = System.nanoTime();
Collections.shuffle(fileList, new Random(seed));
Collections.shuffle(imgList, new Random(seed));

Using two Random objects with the same seed ensures that both lists will be shuffled in exactly the same way. This allows for two separate collections.

The options already listed are very good, however here a few more on this topic that I've researched and came across.

1) http://perfectionkills.com/exploring-canvas-drawing-techniques/
2) http://mcc.id.au/2010/signature.html
3) https://zipso.net/a-simple-touchscreen-sketchpad-using-javascript-and-html5/

And as always you may want to save the canvas to image:

good luck and happy signing

Cast works where the actual instance of the list is an ArrayList. If it is, say, a Vector (which is another extension of List) it will throw a ClassCastException.

The error when changing the definition of your HashMap is due to the elements later being processed, and that process expects a method that is defined only in ArrayList. The exception tells you that it did not found the method it was looking for.

Create a new ArrayList with the contents of the old one.

new ArrayList<String>(myList);

Clone the repository as normal:

git clone git://github.com/rspec/rspec-tmbundle.git RSpec.tmbundle

Then checkout the tag you want like so:

git checkout tags/1.1.4

This will checkout out the tag in a 'detached HEAD' state. In this state, "you can look around, make experimental changes and commit them, and [discard those commits] without impacting any branches by performing another checkout".

To retain any changes made, move them to a new branch:

git checkout -b 1.1.4-jspooner

You can get back to the master branch by using:

git checkout master

Note, as was mentioned in the first revision of this answer, there is another way to checkout a tag:

git checkout 1.1.4

But as was mentioned in a comment, if you have a branch by that same name, this will result in git warning you that the refname is ambiguous and checking out the branch by default:

warning: refname 'test' is ambiguous.
Switched to branch '1.1.4'

The shorthand can be safely used if the repository does not share names between branches and tags.

@Jan Kuiken's answer is certainly well-thought and thorough, but there are some caveats:

• it does not work in all cases
• it requires a fair amount of extra code
• it may vary considerably from one plot to the next

A much simpler approach is to annotate the last point of each plot. The point can also be circled, for emphasis. This can be accomplished with one extra line:

from matplotlib import pyplot as plt

for i, (x, y) in enumerate(samples):
    plt.plot(x, y)
    plt.text(x[-1], y[-1], 'sample {i}'.format(i=i))

A variant would be to use ax.annotate.

In SQL Management Studio you can:

1. Right click on the result set grid, select 'Save Result As...' and save in.

2. On a tool bar toggle 'Result to Text' button. This will prompt for file name on each query run.

If you need to automate it, use bcp tool.

The basic idea of Servlet container is using Java to dynamically generate the web page on the server side using Servlets and JSP. So servlet container is essentially a part of a web server that interacts with the servlets.

As ping works, but telnetto port 80 does not, the HTTP port 80 is closed on your machine. I assume that your browser's HTTP connection goes through a proxy (as browsing works, how else would you read stackoverflow?). You need to add some code to your python program, that handles the proxy, like described here:

Using an HTTP PROXY - Python

A .sql file is a set of commands that can be executed against the SQL server.

Sometimes the .sql file will specify the database, other times you may need to specify this.

You should talk to your DBA or whoever is responsible for maintaining your databases. They will probably want to give the file a quick look. .sql files can do a lot of harm, even inadvertantly.

See the other answers if you want to plunge ahead.

very late to the party here I know but I was thinking about the most elegant way of doing this if you were given a range of delimiters rather than whitespace, and using nothing more than the standard library.

Here are my thoughts:

To split words into a string vector by a sequence of delimiters:

template<class Container>
std::vector<std::string> split_by_delimiters(const std::string& input, const Container& delimiters)
{
    std::vector<std::string> result;

    for (auto current = begin(input) ; current != end(input) ; )
    {
        auto first = find_if(current, end(input), not_in(delimiters));
        if (first == end(input)) break;
        auto last = find_if(first, end(input), is_in(delimiters));
        result.emplace_back(first, last);
        current = last;
    }
    return result;
}

to split the other way, by providing a sequence of valid characters:

template<class Container>
std::vector<std::string> split_by_valid_chars(const std::string& input, const Container& valid_chars)
{
    std::vector<std::string> result;

    for (auto current = begin(input) ; current != end(input) ; )
    {
        auto first = find_if(current, end(input), is_in(valid_chars));
        if (first == end(input)) break;
        auto last = find_if(first, end(input), not_in(valid_chars));
        result.emplace_back(first, last);
        current = last;
    }
    return result;
}

is_in and not_in are defined thus:

namespace detail {
    template<class Container>
    struct is_in {
        is_in(const Container& charset)
        : _charset(charset)
        {}

        bool operator()(char c) const
        {
            return find(begin(_charset), end(_charset), c) != end(_charset);
        }

        const Container& _charset;
    };

    template<class Container>
    struct not_in {
        not_in(const Container& charset)
        : _charset(charset)
        {}

        bool operator()(char c) const
        {
            return find(begin(_charset), end(_charset), c) == end(_charset);
        }

        const Container& _charset;
    };

}

template<class Container>
detail::not_in<Container> not_in(const Container& c)
{
    return detail::not_in<Container>(c);
}

template<class Container>
detail::is_in<Container> is_in(const Container& c)
{
    return detail::is_in<Container>(c);
}

The imshow() function with parameters interpolation='nearest' and cmap='hot' should do what you want.

import matplotlib.pyplot as plt
import numpy as np

a = np.random.random((16, 16))
plt.imshow(a, cmap='hot', interpolation='nearest')
plt.show()

The difference concerns redirecting POST, PUT and DELETE requests and what the expectations of the server are for the user agent behavior (RFC 2616):

Note: RFC 1945 and RFC 2068 specify that the client is not allowed to change the method on the redirected request. However, most existing user agent implementations treat 302 as if it were a 303 response, performing a GET on the Location field-value regardless of the original request method. The status codes 303 and 307 have been added for servers that wish to make unambiguously clear which kind of reaction is expected of the client.

Also, read Wikipedia article on the 30x redirection codes.

A good library available named log4j for Java.
This will provide numerous feature. Go through link and you will find your solution.

Regex can be used for this with some detailed info for validation, for example this code can be used to validate any date in (DD/MM/yyyy) format with proper date and month value and year between (1950-2050)

    public Boolean checkDateformat(String dateToCheck){   
        String rex="([0]{1}[1-9]{1}|[1-2]{1}[0-9]{1}|[3]{1}[0-1]{1})+
        \/([0]{1}[1-9]{1}|[1]{1}[0-2]{2})+
        \/([1]{1}[9]{1}[5-9]{1}[0-9]{1}|[2]{1}[0]{1}([0-4]{1}+
        [0-9]{1}|[5]{1}[0]{1}))";

        return(dateToCheck.matches(rex));
    }

Load an image with characters as texture and draw the part of that texture depending on what character you want. You can create that texture using a paint program, hardcode it or use a window component to draw to an image and retrieve that image for an exact copy of system fonts.

No need to use Glut or any other extension, just basic OpenGL operability. It gets the job done, not to mention that its been done like this for decades by professional programmers in very succesfull games and other applications.

You put all threads in an array, start them all, and then have a loop

for(i = 0; i < threads.length; i++)
  threads[i].join();

Each join will block until the respective thread has completed. Threads may complete in a different order than you joining them, but that's not a problem: when the loop exits, all threads are completed.

If you're not interested in the details that git diff outputs you can just run git cherry which will output a list of commits your remote tracking branch has ahead of your local branch.

For example:

git fetch origin
git cherry master origin/master

Will output something like :

+ 2642039b1a4c4d4345a0d02f79ccc3690e19d9b1
+ a4870f9fbde61d2d657e97b72b61f46d1fd265a9

Indicates that there are two commits in my remote tracking branch that haven't been merged into my local branch.

This also works the other way :

    git cherry origin/master master

Will show you a list of local commits that you haven't pushed to your remote repository yet.

I got this same error when installing to an actual device. More information and a solution to loading the missing libraries to the device can be found at the following site:

Fixing the INSTALL_FAILED_MISSING_SHARED_LIBRARY Error

To set this up correctly, there are 2 key files that need to be copied to the system:

com.google.android.maps.xml

com.google.android.maps.jar

These files are located in the any of these google app packs:

http://android.d3xt3...0120-signed.zip

http://goo-inside.me...0120-signed.zip

http://android.local...0120-signed.zip

These links no longer work, but you can find the files in the android sdk if you have Google Maps API v1

After unzipping any of these files, you want to copy the files to your system, like-ah-so:

adb remount

adb push system/etc/permissions/com.google.android.maps.xml /system/etc/permissions

adb push system/framework/com.google.android.maps.jar /system/framework

adb reboot

Vue.js props are not to be mutated as this is considered an Anti-Pattern in Vue.

The approach you will need to take is creating a data property on your component that references the original prop property of list

props: ['list'],
data: () {
  return {
    parsedList: JSON.parse(this.list)
  }
}

Now your list structure that is passed to the component is referenced and mutated via the data property of your component :-)

If you wish to do more than just parse your list property then make use of the Vue component' computed property. This allow you to make more in depth mutations to your props.

props: ['list'],
computed: {
  filteredJSONList: () => {
    let parsedList = JSON.parse(this.list)
    let filteredList = parsedList.filter(listItem => listItem.active)
    console.log(filteredList)
    return filteredList
  }
}

The example above parses your list prop and filters it down to only active list-tems, logs it out for schnitts and giggles and returns it.

note: both data & computed properties are referenced in the template the same e.g

<pre>{{parsedList}}</pre>

<pre>{{filteredJSONList}}</pre>

It can be easy to think that a computed property (being a method) needs to be called... it doesn't

If you go through the documentation, they have mentioned to use php composer.phar Link: https://getcomposer.org/doc/03-cli.md#update-u

Don't use php composer.phar only give composer

Command: composer self-update

It will work.

The other answers here are correct, but they don't get into how instanceof actually works, which may be of interest to some language lawyers out there.

Every object in JavaScript has a prototype, accessible through the __proto__ property. Functions also have a prototype property, which is the initial __proto__ for any objects created by them. When a function is created, it is given a unique object for prototype. The instanceof operator uses this uniqueness to give you an answer. Here's what instanceof might look like if you wrote it as a function.

function instance_of(V, F) {
  var O = F.prototype;
  V = V.__proto__;
  while (true) {
    if (V === null)
      return false;
    if (O === V)
      return true;
    V = V.__proto__;
  }
}

This is basically paraphrasing ECMA-262 edition 5.1 (also known as ES5), section 15.3.5.3.

Note that you can reassign any object to a function's prototype property, and you can reassign an object's __proto__ property after it is constructed. This will give you some interesting results:

function F() { }
function G() { }
var p = {};
F.prototype = p;
G.prototype = p;
var f = new F();
var g = new G();

f instanceof F;   // returns true
f instanceof G;   // returns true
g instanceof F;   // returns true
g instanceof G;   // returns true

F.prototype = {};
f instanceof F;   // returns false
g.__proto__ = {};
g instanceof G;   // returns false

Scrubyt uses Ruby and Hpricot to do nice and easy web scraping. I wrote a scraper for my university's library service using this in about 30 minutes.

Given that Windows has no sys/socket.h, you might consider just doing something like this:

#ifdef __WIN32__
# include <winsock2.h>
#else
# include <sys/socket.h>
#endif

I know you indicated that you won't use WinSock, but since WinSock is how TCP networking is done under Windows, I don't see that you have any alternative. Even if you use a cross-platform networking library, that library will be calling WinSock internally. Most of the standard BSD sockets API calls are implemented in WinSock, so with a bit of futzing around, you can make the same sockets-based program compile under both Windows and other OS's. Just don't forget to do a

#ifdef __WIN32__
   WORD versionWanted = MAKEWORD(1, 1);
   WSADATA wsaData;
   WSAStartup(versionWanted, &wsaData);
#endif

at the top of main()... otherwise all of your socket calls will fail under Windows, because the WSA subsystem wasn't initialized for your process.

For modern browsers

When you have that luxury. There's flexbox too, but that's not broadly supported at the time of this writing.

HTML:

<div class="content">This works with any content</div>

CSS:

.content {
  position: absolute;
  left: 50%;
  top: 50%;
  -webkit-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
}

Tinker with it further on Codepen or on JSBin

For older browser support, look elsewhere in this thread.
