In ASP.NET 5 rc1-final, I did following:

Created ApplicationRoleManager (in similar manner as there is ApplicationUser created by template)

public class ApplicationRoleManager : RoleManager<IdentityRole>
{
    public ApplicationRoleManager(
        IRoleStore<IdentityRole> store,
        IEnumerable<IRoleValidator<IdentityRole>> roleValidators,
        ILookupNormalizer keyNormalizer,
        IdentityErrorDescriber errors,
        ILogger<RoleManager<IdentityRole>> logger,
        IHttpContextAccessor contextAccessor)
        : base(store, roleValidators, keyNormalizer, errors, logger, contextAccessor)
    {
    }
}

To ConfigureServices in Startup.cs, I added it as RoleManager

services.
    .AddIdentity<ApplicationUser, IdentityRole>()
    .AddRoleManager<ApplicationRoleManager>();

For creating new Roles, call from Configure following:

public static class RoleHelper
{
    private static async Task EnsureRoleCreated(RoleManager<IdentityRole> roleManager, string roleName)
    {
        if (!await roleManager.RoleExistsAsync(roleName))
        {
            await roleManager.CreateAsync(new IdentityRole(roleName));
        }
    }
    public static async Task EnsureRolesCreated(this RoleManager<IdentityRole> roleManager)
    {
        // add all roles, that should be in database, here
        await EnsureRoleCreated(roleManager, "Developer");
    }
}

public async void Configure(..., RoleManager<IdentityRole> roleManager, ...)
{
     ...
     await roleManager.EnsureRolesCreated();
     ...
}

Now, the rules can be assigned to user

await _userManager.AddToRoleAsync(await _userManager.FindByIdAsync(User.GetUserId()), "Developer");

Or used in Authorize attribute

[Authorize(Roles = "Developer")]
public class DeveloperController : Controller
{
}

Use count(*)

declare 
   cnt integer;
begin
  SELECT count(*) INTO cnt
  FROM people
  WHERE person_id = my_person_id;

IF cnt > 0 THEN
  -- Do something
END IF;

Edit (for the downvoter who didn't read the statement and others who might be doing something similar)

The solution is only effective because there is a where clause on a column (and the name of the column suggests that its the primary key - so the where clause is highly effective)

Because of that where clause there is no need to use a LIMIT or something else to test the presence of a row that is identified by its primary key. It is an effective way to test this.

How about this?

for (let [key, value] of Object.entries(obj)) {
    ...
}

the shortest way

re.sub(r'http\S+', '', stringliteral)

If you need to organize data in columns of 1 / 2 / 4 depending of the viewport size then push and pull may be no option at all. No matter how you order your items in the first place, one of the sizes may give you a wrong order.

A solution in this case is to use nested rows and cols without any push or pull classes.

Example

In XS you want...

A
B
C
D
E
F
G
H

In SM you want...

A   E
B   F
C   G
D   H

In MD and above you want...

A   C   E   G
B   D   F   H

Solution

Use nested two-column child elements in a surrounding two-column parent element:

Here is a working snippet:

<script src="https://code.jquery.com/jquery-1.12.4.min.js" type="text/javascript" ></script>_x000D_
<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"> _x000D_
<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>_x000D_
_x000D_
<div class="row">_x000D_
  <div class="col-sm-6">_x000D_
    <div class="row">_x000D_
      <div class="col-md-6"><p>A</p><p>B</p></div>_x000D_
      <div class="col-md-6"><p>C</p><p>D</p></div>_x000D_
    </div>_x000D_
  </div>_x000D_
  <div class="col-sm-6">_x000D_
    <div class="row">_x000D_
      <div class="col-md-6"><p>E</p><p>F</p></div>_x000D_
      <div class="col-md-6"><p>G</p><p>H</p></div>_x000D_
    </div>_x000D_
  </div>_x000D_
</div>

Another beauty of this solution is, that the items appear in the code in their natural order (A, B, C, ... H) and don't have to be shuffled, which is nice for CMS generation.

The excellent JavaScript library KeyboardJS handles all types of key presses including the SHIFT key. It even allows specifying key combinations such as first pressing CTRL+x and then a.

KeyboardJS.on('shift', function() { ...handleDown... }, function() { ...handleUp... });

If you want a simple version, head to the answer by @tonycoupland):

var shiftHeld = false;
$('#control').on('mousedown', function (e) { shiftHeld = e.shiftKey });

try the array_count_values() function

<?php
$array = array(1, "hello", 1, "world", "hello");
print_r(array_count_values($array));
?>

output:

Array
(
    [1] => 2
    [hello] => 2
    [world] => 1
)

http://php.net/manual/en/function.array-count-values.php

This can be done in many ways. a. Using nested inside a tag.

<a href="link1.html">
   <div> Something in the div </div>
 </a>

b. Using the Inline JavaScript Method

<div onclick="javascript:window.location.href='link1.html' "> 
  Some Text 
</div>

c. Using jQuery inside tag

HTML:

<div class="demo" > Some text here </div>

jQuery:

$(".demo").click( function() {
  window.location.href="link1.html";
 });

Unfortunately, combining multiple entity contexts into a single named connection isn't possible. If you want to use named connection strings from a .config file to define your Entity Framework connections, they will each have to have a different name. By convention, that name is typically the name of the context:

<add name="ModEntity" connectionString="metadata=res://*/ModEntity.csdl|res://*/ModEntity.ssdl|res://*/ModEntity.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=SomeServer;Initial Catalog=SomeCatalog;Persist Security Info=True;User ID=Entity;Password=SomePassword;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />
<add name="Entity" connectionString="metadata=res://*/Entity.csdl|res://*/Entity.ssdl|res://*/Entity.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=SOMESERVER;Initial Catalog=SOMECATALOG;Persist Security Info=True;User ID=Entity;Password=Entity;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />

However, if you end up with namespace conflicts, you can use any name you want and simply pass the correct name to the context when it is generated:

var context = new Entity("EntityV2");

Obviously, this strategy works best if you are using either a factory or dependency injection to produce your contexts.

Another option would be to produce each context's entire connection string programmatically, and then pass the whole string in to the constructor (not just the name).

// Get "Data Source=SomeServer..."
var innerConnectionString = GetInnerConnectionStringFromMachinConfig();
// Build the Entity Framework connection string.
var connectionString = CreateEntityConnectionString("Entity", innerConnectionString);
var context = new EntityContext(connectionString);

How about something like this:

Type contextType = typeof(test_Entities);
string innerConnectionString = ConfigurationManager.ConnectionStrings["Inner"].ConnectionString;
string entConnection = 
    string.Format(
        "metadata=res://*/{0}.csdl|res://*/{0}.ssdl|res://*/{0}.msl;provider=System.Data.SqlClient;provider connection string=\"{1}\"",
        contextType.Name,
        innerConnectionString);
object objContext = Activator.CreateInstance(contextType, entConnection);
return objContext as test_Entities; 

... with the following in your machine.config:

<add name="Inner" connectionString="Data Source=SomeServer;Initial Catalog=SomeCatalog;Persist Security Info=True;User ID=Entity;Password=SomePassword;MultipleActiveResultSets=True" providerName="System.Data.SqlClient" />

This way, you can use a single connection string for every context in every project on the machine.

I think you will need to edit the doxys file and set GENERATE_UML (something like that) to true. And you need to have dot/graphviz installed.

Use this:

ALTER TABLE users AUTO_INCREMENT=1001;

or if you haven't already added an id column, also add it

ALTER TABLE users ADD id INT UNSIGNED NOT NULL AUTO_INCREMENT,
    ADD INDEX (id);

What about:

SELECT COUNT(*) FROM (SELECT ID FROM Movies GROUP BY ID HAVING COUNT(Genre)=4) a

Using ES6 syntax does not work in node, unfortunately, you have to have babel apparently to make the compiler understand syntax such as export or import.

npm install babel-cli --save

Now we need to create a .babelrc file, in the babelrc file, we’ll set babel to use the es2015 preset we installed as its preset when compiling to ES5.

At the root of our app, we’ll create a .babelrc file. $ npm install babel-preset-es2015 --save

At the root of our app, we’ll create a .babelrc file.

{  "presets": ["es2015"] }

Hope it works ... :)

The usual way to do this is to set the Form's AcceptButton to the button you want "clicked". You can do this either in the VS designer or in code and the AcceptButton can be changed at any time.

This may or may not be applicable to your situation, but I have used this in conjunction with GotFocus events for different TextBoxes on my form to enable different behavior based on where the user hit Enter. For example:

void TextBox1_GotFocus(object sender, EventArgs e)
{
    this.AcceptButton = ProcessTextBox1;
}

void TextBox2_GotFocus(object sender, EventArgs e)
{
    this.AcceptButton = ProcessTextBox2;
}

One thing to be careful of when using this method is that you don't leave the AcceptButton set to ProcessTextBox1 when TextBox3 becomes focused. I would recommend using either the LostFocus event on the TextBoxes that set the AcceptButton, or create a GotFocus method that all of the controls that don't use a specific AcceptButton call.

If you are running the correct class and the main is properly defined, also check if you have a class called String defined in the same package. This definition of String class will be considered and since it doesn't confirm to main(java.lang.String[] args), you will get the same exception.

• It's not a compile time error since compiler just assumes you are defining a custom main method.

Suggestion is to never hide library java classes in your package.

I have faced same problem ... For the problem is like this, I am calling the PRC inside cpp program and my PRC taking 4 arguments but while calling I used only 1 arguments so this error came for me.

Begin Example_PRC(:1); End; // this cause the problem 
Begin Example_PRC(:1,:2,:3,:4); End; // this is the solution

I have used a tool in my work its LDRA tool suite

It is used for testing the c/c++ code but it also can check against coding standards such as MISRA etc.

CREATE TABLE #tempww (

declare @col varchar(1000)

declare @sql varchar(2000)

select @col = COALESCE(@col + ', ','') + QUOTENAME(DBname)

For the benefit of the reader, this recipe here

• can be re-used as oneliner to catch stderr into a variable
• still gives access to the return code of the command
• Sacrifices a temporary file descriptor 3 (which can be changed by you of course)
• And does not expose this temporary file descriptors to the inner command

If you want to catch stderr of some command into var you can do

{ var="$( { command; } 2>&1 1>&3 3>&- )"; } 3>&1;

Afterwards you have it all:

echo "command gives $? and stderr '$var'";

If command is simple (not something like a | b) you can leave the inner {} away:

{ var="$(command 2>&1 1>&3 3>&-)"; } 3>&1;

Wrapped into an easy reusable bash-function (probably needs version 3 and above for local -n):

: catch-stderr var cmd [args..]
catch-stderr() { local -n v="$1"; shift && { v="$("$@" 2>&1 1>&3 3>&-)"; } 3>&1; }

Explained:

• local -n aliases "$1" (which is the variable for catch-stderr)
• 3>&1 uses file descriptor 3 to save there stdout points
• { command; } (or "$@") then executes the command within the output capturing $(..)
• Please note that the exact order is important here (doing it the wrong way shuffles the file descriptors wrongly):
  • 2>&1 redirects stderr to the output capturing $(..)
  • 1>&3 redirects stdout away from the output capturing $(..) back to the "outer" stdout which was saved in file descriptor 3. Note that stderr still refers to where FD 1 pointed before: To the output capturing $(..)
  • 3>&- then closes the file descriptor 3 as it is no more needed, such that command does not suddenly has some unknown open file descriptor showing up. Note that the outer shell still has FD 3 open, but command will not see it.
  • The latter is important, because some programs like lvm complain about unexpected file descriptors. And lvm complains to stderr - just what we are going to capture!

You can catch any other file descriptor with this recipe, if you adapt accordingly. Except file descriptor 1 of course (here the redirection logic would be wrong, but for file descriptor 1 you can just use var=$(command) as usual).

Note that this sacrifices file descriptor 3. If you happen to need that file descriptor, feel free to change the number. But be aware, that some shells (from the 1980s) might understand 99>&1 as argument 9 followed by 9>&1 (this is no problem for bash).

Also note that it is not particluar easy to make this FD 3 configurable through a variable. This makes things very unreadable:

: catch-var-from-fd-by-fd variable fd-to-catch fd-to-sacrifice command [args..]
catch-var-from-fd-by-fd()
{
local -n v="$1";
local fd1="$2" fd2="$3";
shift 3 || return;

eval exec "$fd2>&1";
v="$(eval '"$@"' "$fd1>&1" "1>&$fd2" "$fd2>&-")";
eval exec "$fd2>&-";
}

Security note: The first 3 arguments to catch-var-from-fd-by-fd must not be taken from a 3rd party. Always give them explicitly in a "static" fashion.

So no-no-no catch-var-from-fd-by-fd $var $fda $fdb $command, never do this!

If you happen to pass in a variable variable name, at least do it as follows: local -n var="$var"; catch-var-from-fd-by-fd var 3 5 $command

This still will not protect you against every exploit, but at least helps to detect and avoid common scripting errors.

Notes:

• catch-var-from-fd-by-fd var 2 3 cmd.. is the same as catch-stderr var cmd..
• shift || return is just some way to prevent ugly errors in case you forget to give the correct number of arguments. Perhaps terminating the shell would be another way (but this makes it hard to test from commandline).
• The routine was written such, that it is more easy to understand. One can rewrite the function such that it does not need exec, but then it gets really ugly.
• This routine can be rewritten for non-bash as well such that there is no need for local -n. However then you cannot use local variables and it gets extremely ugly!
• Also note that the evals are used in a safe fashion. Usually eval is considerered dangerous. However in this case it is no more evil than using "$@" (to execute arbitrary commands). However please be sure to use the exact and correct quoting as shown here (else it becomes very very dangerous).

When the propagation setting is PROPAGATION_REQUIRED, a logical transaction scope is created for each method upon which the setting is applied. Each such logical transaction scope can determine rollback-only status individually, with an outer transaction scope being logically independent from the inner transaction scope. Of course, in case of standard PROPAGATION_REQUIRED behavior, all these scopes will be mapped to the same physical transaction. So a rollback-only marker set in the inner transaction scope does affect the outer transaction's chance to actually commit (as you would expect it to).

All of these other answers include runtime overhead... like using ArrayList.toString().replaceAll(...) which are very wasteful.

I will give you the optimal algorithm with zero overhead; it doesn't look as pretty as the other options, but internally, this is what they are all doing (after piles of other hidden checks, multiple array allocation and other crud).

Since you already know you are dealing with strings, you can save a bunch of array allocations by performing everything manually. This isn't pretty, but if you trace the actual method calls made by the other implementations, you'll see it has the least runtime overhead possible.

public static String join(String separator, String ... values) {
  if (values.length==0)return "";//need at least one element
  //all string operations use a new array, so minimize all calls possible
  char[] sep = separator.toCharArray();

  // determine final size and normalize nulls
  int totalSize = (values.length - 1) * sep.length;// separator size
  for (int i = 0; i < values.length; i++) {
    if (values[i] == null)
      values[i] = "";
    else
      totalSize += values[i].length();
  }

  //exact size; no bounds checks or resizes
  char[] joined = new char[totalSize];
  int pos = 0;
  //note, we are iterating all the elements except the last one
  for (int i = 0, end = values.length-1; i < end; i++) {
    System.arraycopy(values[i].toCharArray(), 0, 
      joined, pos, values[i].length());
    pos += values[i].length();
    System.arraycopy(sep, 0, joined, pos, sep.length);
    pos += sep.length;
  }
  //now, add the last element; 
  //this is why we checked values.length == 0 off the hop
  System.arraycopy(values[values.length-1].toCharArray(), 0,
    joined, pos, values[values.length-1].length());

  return new String(joined);
}

You just need to write the first query as a subquery (derived table), inside parentheses, pick an alias for it (t below) and alias the columns as well.

The DISTINCT can also be safely removed as the internal GROUP BY makes it redundant:

SELECT DATE(`date`) AS `date` , COUNT(`player_name`) AS `player_count`
FROM (
    SELECT MIN(`date`) AS `date`, `player_name`
    FROM `player_playtime`
    GROUP BY `player_name`
) AS t
GROUP BY DATE( `date`) DESC LIMIT 60 ;

Since the COUNT is now obvious that is only counting rows of the derived table, you can replace it with COUNT(*) and further simplify the query:

SELECT t.date , COUNT(*) AS player_count
FROM (
    SELECT DATE(MIN(`date`)) AS date
    FROM player_playtime
    GROUP BY player_name
) AS t
GROUP BY t.date DESC LIMIT 60 ;

Try with this

echo date("G:i", strtotime($time));

or you can try like this also

echo date("H:i", strtotime("04:25 PM"));

Current css version still doesn't support selector find by content. But there is a way, by using css selector find by attribute, but you have to put some identifier on all of the <td> that have $ inside. Example: using nth-child in tables tr td

html

<tr>
    <td>&nbsp;</td>
    <td data-rel='$'>$</td>
    <td>&nbsp;</td>
</tr>

css

table tr td[data-rel='$'] {
    background-color: #333;
    color: white;
}

Please try these example.

table tr td[data-content='$'] {_x000D_
    background-color: #333;_x000D_
    color: white;_x000D_
}

<table border="1">_x000D_
    <tr>_x000D_
        <td>A</td>_x000D_
        <td data-content='$'>$</td>_x000D_
        <td>B</td>_x000D_
        <td data-content='$'>$</td>_x000D_
        <td>C</td>_x000D_
        <td data-content='$'>$</td>_x000D_
        <td>D</td>_x000D_
    </tr>_x000D_
</table>

You can use the monitoring program glances with its GPU monitoring plug-in:

• open source
• to install: sudo apt-get install -y python-pip; sudo pip install glances[gpu]
• to launch: sudo glances

It also monitors the CPU, disk IO, disk space, network, and a few other things:

As has been mentioned in other answers, there is no pure HTML5 way to do this.

If you are already using JQuery, then this should do what you need:

$(document).ready(function() {_x000D_
  $('#ourForm').submit(function(e){_x000D_
      var form = this;_x000D_
      e.preventDefault();_x000D_
      // Check Passwords are the same_x000D_
      if( $('#pass1').val()==$('#pass2').val() ) {_x000D_
          // Submit Form_x000D_
          alert('Passwords Match, submitting form');_x000D_
          form.submit();_x000D_
      } else {_x000D_
          // Complain bitterly_x000D_
          alert('Password Mismatch');_x000D_
          return false;_x000D_
      }_x000D_
  });_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<form id="ourForm">_x000D_
    <input type="password" name="password" id="pass1" placeholder="Password" required>_x000D_
    <input type="password" name="password" id="pass2" placeholder="Repeat Password" required>_x000D_
    <input type="submit" value="Go">_x000D_
</form>

I think you should store the size somewhere.

The null-terminated-string kind of model for determining array length is a bad idea. For instance, getting the size of the array will be O(N) when it could very easily have been O(1) otherwise.

Having that said, a good solution might be glib's Arrays, they have the added advantage of expanding automatically if you need to add more items.

P.S. to be completely honest, I haven't used much of glib, but I think it's a (very) reputable library.

objectForKey: will return nil if it doesn't exist.

This code can help you :

$(document).ready(function() { 
    $('#calendar').fullCalendar({ 
        events: 
            [ 
                { 
                    id: 1, 
                    title: 'First Event', 
                    start: ..., 
                    end: ..., 
                    description: 'first description' 
                }, 
                { 
                    id: 2, 
                    title: 'Second Event', 
                    start: ..., 
                    end: ..., 
                    description: 'second description'
                }
            ], 
        eventRender: function(event, element) { 
            element.find('.fc-title').append("<br/>" + event.description); 
        } 
    });
}   

This is my solution using pure Win32/C++ based on the top answer. The idea is to wrap everything required into one function without the need for external callback functions or structures:

#include <utility>

HWND FindTopWindow(DWORD pid)
{
    std::pair<HWND, DWORD> params = { 0, pid };

    // Enumerate the windows using a lambda to process each window
    BOOL bResult = EnumWindows([](HWND hwnd, LPARAM lParam) -> BOOL 
    {
        auto pParams = (std::pair<HWND, DWORD>*)(lParam);

        DWORD processId;
        if (GetWindowThreadProcessId(hwnd, &processId) && processId == pParams->second)
        {
            // Stop enumerating
            SetLastError(-1);
            pParams->first = hwnd;
            return FALSE;
        }

        // Continue enumerating
        return TRUE;
    }, (LPARAM)&params);

    if (!bResult && GetLastError() == -1 && params.first)
    {
        return params.first;
    }

    return 0;
}

counter[row[11]]+=1

You don't show what data is, but apparently when you loop through its rows, row[11] is turning out to be a list. Lists are mutable objects which means they cannot be used as dictionary keys. Trying to use row[11] as a key causes the defaultdict to complain that it is a mutable, i.e. unhashable, object.

The easiest fix is to change row[11] from a list to a tuple. Either by doing

counter[tuple(row[11])] += 1

or by fixing it in the caller before data is passed to medications_minimum3. A tuple simply an immutable list, so it behaves exactly like a list does except you cannot change it once it is created.

I got the same problem also. Here's what I did:

If you're already done granting the user/group the rights to use the profile name.

1. Go to the configuration Wizard of Database Mail
2. Tick Manage profile security
3. On public profiles tab, check your profile name
4. On private profiles tab, select NT AUTHORITY\NETWORK SERVICE for user name and check your profile name
5. Do #4 this time for NT AUTHORITY\SYSTEM user name
6. Click Next until Finish.

One additional reason to allow and use std::unique_ptr<T[]>, that hasn't been mentioned in the responses so far: it allows you to forward-declare the array element type.

This is useful when you want to minimize the chained #include statements in headers (to optimize build performance.)

For instance -

myclass.h:

class ALargeAndComplicatedClassWithLotsOfDependencies;

class MyClass {
   ...
private:
   std::unique_ptr<ALargeAndComplicatedClassWithLotsOfDependencies[]> m_InternalArray;
};

myclass.cpp:

#include "myclass.h"
#include "ALargeAndComplicatedClassWithLotsOfDependencies.h"

// MyClass implementation goes here

With the above code structure, anyone can #include "myclass.h" and use MyClass, without having to include the internal implementation dependencies required by MyClass::m_InternalArray.

If m_InternalArray was instead declared as a std::array<ALargeAndComplicatedClassWithLotsOfDependencies>, or a std::vector<...>, respectively - the result would be attempted usage of an incomplete type, which is a compile-time error.

If you want to see the array as an array, you can say

alert(JSON.stringify(aCustomers));

instead of all those document.writes.

http://jsfiddle.net/5b2eb/

However, if you want to display them cleanly, one per line, in your popup, do this:

alert(aCustomers.join("\n"));

http://jsfiddle.net/5b2eb/1/

You should simply return your object, and shouldn't be concerned about whether its XML or JSON. It is the client responsibility to request JSON or XML from the web api. For example, If you make a call using Internet explorer then the default format requested will be Json and the Web API will return Json. But if you make the request through google chrome, the default request format is XML and you will get XML back.

If you make a request using Fiddler then you can specify the Accept header to be either Json or XML.

Accept: application/xml

You may wanna see this article: Content Negotiation in ASP.NET MVC4 Web API Beta – Part 1

EDIT: based on your edited question with code:

Simple return list of string, instead of converting it to XML. try it using Fiddler.

public List<string> Get(int tenantID, string dataType, string ActionName)
    {
       List<string> SQLResult = MyWebSite_DataProvidor.DB.spReturnXMLData("SELECT * FROM vwContactListing FOR XML AUTO, ELEMENTS").ToList();
       return SQLResult;
     }

For example if your list is like:

List<string> list = new List<string>();
list.Add("Test1");
list.Add("Test2");
list.Add("Test3");
return list;

and you specify Accept: application/xml the output will be:

<ArrayOfstring xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
  <string>Test1</string>
  <string>Test2</string>
  <string>Test3</string>
</ArrayOfstring>

and if you specify 'Accept: application/json' in the request then the output will be:

[
  "Test1",
  "Test2",
  "Test3"
]

So let the client request the content type, instead of you sending the customized xml.

Here is how it worked for me:

After "vagrant up" started the virtual machine, turned off the machine and go to the new virtual machine settings in virtualbox. Then go to "Network" -> "Advanced"

Adapter Type: I changed from "Intel PRO XXXXX" to "PCNet-Fast" (or any other adpter other than Intel PRO did work)

My preference is to keep the formatting details with the view and not the viewmodel. So in MVC4/Razor:

@Html.TextBoxFor(model => model.DateTime, "{0:d}");

datetime format reference: http://msdn.microsoft.com/en-us/library/az4se3k1(v=vs.71).aspx

Then I have a JQuery datepicker bound to it, and that put's the date in as a different format...doh!

Looks like I need to set the datepicker's format to the same formatting.

So I'm storing the System.Globalization formatting in a data-* attribute and collecting it when setting up the

@Html.TextBoxFor(
    model => model.DateTime.Date, 
    "{0:d}", 
    new 
    { 
        @class = "datePicker", 
        @data_date_format=System.Globalization.CultureInfo
                          .CurrentUICulture.DateTimeFormat.ShortDatePattern 
    }));

And here's the sucky part: the formats of .net and datepicker do not match, so hackery is needed:

$('.datePicker').each(function(){
    $(this).datepicker({
        dateFormat:$(this).data("dateFormat").toLowerCase().replace("yyyy","yy")
    });
});

that's kind of weak, but should cover a lot of cases.

Usually you don't have to worry about calculating them as your assembler (or linker) will take of getting the calculations right. Let's say you have a small function:

func:
  slti $t0, $a0, 2
  beq $t0, $zero, cont
  ori $v0, $zero, 1
  jr $ra
cont:
  ...
  jal func
  ... 

When translating the above code into a binary stream of instructions the assembler (or linker if you first assembled into an object file) it will be determined where in memory the function will reside (let's ignore position independent code for now). Where in memory it will reside is usually specified in the ABI or given to you if you're using a simulator (like SPIM which loads the code at 0x400000 - note the link also contains a good explanation of the process).

Assuming we're talking about the SPIM case and our function is first in memory, the slti instruction will reside at 0x400000, the beq at 0x400004 and so on. Now we're almost there! For the beq instruction the branch target address is that of cont (0x400010) looking at a MIPS instruction reference we see that it is encoded as a 16-bit signed immediate relative to the next instruction (divided by 4 as all instructions must reside on a 4-byte aligned address anyway).

That is:

Current address of instruction + 4 = 0x400004 + 4 = 0x400008
Branch target = 0x400010
Difference = 0x400010 - 0x400008 = 0x8
To encode = Difference / 4 = 0x8 / 4 = 0x2 = 0b10

Encoding of beq $t0, $zero, cont

0001 00ss ssst tttt iiii iiii iiii iiii
---------------------------------------
0001 0001 0000 0000 0000 0000 0000 0010

As you can see you can branch to within -0x1fffc .. 0x20000 bytes. If for some reason, you need to jump further you can use a trampoline (an unconditional jump to the real target placed placed within the given limit).

Jump target addresses are, unlike branch target addresses, encoded using the absolute address (again divided by 4). Since the instruction encoding uses 6 bits for the opcode, this only leaves 26 bits for the address (effectively 28 given that the 2 last bits will be 0) therefore the 4 bits most significant bits of the PC register are used when forming the address (won't matter unless you intend to jump across 256 MB boundaries).

Returning to the above example the encoding for jal func is:

Destination address = absolute address of func = 0x400000
Divided by 4 = 0x400000 / 4 = 0x100000
Lower 26 bits = 0x100000 & 0x03ffffff = 0x100000 = 0b100000000000000000000

0000 11ii iiii iiii iiii iiii iiii iiii
---------------------------------------
0000 1100 0001 0000 0000 0000 0000 0000

You can quickly verify this, and play around with different instructions, using this online MIPS assembler i ran across (note it doesn't support all opcodes, for example slti, so I just changed that to slt here):

00400000: <func>    ; <input:0> func:
00400000: 0000002a  ; <input:1> slt $t0, $a0, 2
00400004: 11000002  ; <input:2> beq $t0, $zero, cont
00400008: 34020001  ; <input:3> ori $v0, $zero, 1
0040000c: 03e00008  ; <input:4> jr $ra
00400010: <cont>    ; <input:5> cont:
00400010: 0c100000  ; <input:7> jal func

You need the python-dev package which contains Python.h

In case you need to do it in one line command with bash script as below:

$ cd /path/to/your/repo && /bin/bash $HOME/remove_submodule.sh /path/to/the/submodule

Create bash script file in the $HOME dir named i.e. remove_submodule.sh:

#!/bin/bash

git config -f .gitmodules --remove-section submodule.$1
git config -f .git/config --remove-section submodule.$1
git rm --cached $1
git add .gitmodules
git commit -m "Remove submodule in $1"
rm -rf $1
rm -rf .git/modules/$1
git push origin $(git rev-parse --abbrev-ref HEAD) --force --quiet

uint16_t is guaranteed to be a unsigned integer that is 16 bits large

unsigned short int is guaranteed to be a unsigned short integer, where short integer is defined by the compiler (and potentially compiler flags) you are currently using. For most compilers for x86 hardware a short integer is 16 bits large.

Also note that per the ANSI C standard only the minimum size of 16 bits is defined, the maximum size is up to the developer of the compiler

Minimum Type Limits

Any compiler conforming to the Standard must also respect the following limits with respect to the range of values any particular type may accept. Note that these are lower limits: an implementation is free to exceed any or all of these. Note also that the minimum range for a char is dependent on whether or not a char is considered to be signed or unsigned.

Type Minimum Range

signed char     -127 to +127
unsigned char      0 to 255
short int     -32767 to +32767
unsigned short int 0 to 65535

This was my stupidity, but a stupidity that was not easy to identify :).

Problem:

1. My code is compiled on Jdk 1.8.
2. My eclipse, had JDK 1.8 as the compiler.
3. My tomcat in eclipse was using Java 1.7 for its container, hence it was not able to understand the .class files which were compiled using 1.8.
4. To avoid the problem, ensure in your eclipse, double click on your server -> Open Launch configuration -> Classpath -> JRE System Library -> Give the JDK/JRE of the compiled version of java class, in my case, it had to be JDK 1.8
   5. Post this, clean the server, build and redeploy, start the tomcat.

If you are deploying manually into your server, ensure your JAVA_HOME, JDK_HOME points to the correct JDK which you used to compile the project and build the war.

If you do not like to change JAVA_HOME, JDK_HOME, you can always change the JAVA_HOME and JDK_HOME in catalina.bat(for tomcat server) and that'll enable your life to be easy!

Make sure you still have phpMyAdmin maybe you deleted it in your htdocs folder?

Unzip then place the phpMyAdmin (rename the folder if it has version numbers) in your htdocs folder.

Make sure Skype is disabled as it will some times run on the same port as your XAMPP install... I'm not sure why but apache installed via xampp on some windows 7 machines ive seen apache not run if skype is on after 10years of IT work.

So make sure apache is running, mysql is running and hit:

You should get some kind of install prompt. Step through this you will learn lots along the way. But basically its one config file that needs some settings.

I share your sense that Interfaces are not necessary. Here is a quote from Cwalina pg 80 Framework Design Guidelines "I often here people saying that interfaces specify contracts. I believe this a dangerous myth. Interfaces by themselves do not specify much. ..." He and co-author Abrams managed 3 releases of .Net for Microsoft. He goes on to say that the 'contract' is "expressed" in an implementation of the class. IMHO watching this for decades, there were many people warning Microsoft that taking the engineering paradigm to the max in OLE/COM might seem good but its usefulness is more directly to hardware. Especially in a big way in the 80s and 90s getting interoperating standards codified. In our TCP/IP Internet world there is little appreciation of the hardware and software gymnastics we would jump through to get solutions 'wired up' between and among mainframes, minicomputers, and microprocessors of which PCs were just a small minority. So coding to interfaces and their protocols made computing work. And interfaces ruled. But what does solving making X.25 work with your application have in common with posting recipes for the holidays? I have been coding C++ and C# for many years and I never created one once.

If you are working with Application Pool authentication (instead of IUSR), which you should, then this list of checks by Jean Sun is the very best I could find to deal with 401 errors in IIS:

Open IIS Manager, navigate to your website or application folder where the site is deployed to.

1. Open Advanced Settings (it's on the right hand Actions pane).
2. Note down the Application Pool name then close this window
3. Double click on the Authentication icon to open the authentication settings
4. Disable Windows Authentication
5. Right click on Anonymous Authentication and click Edit
6. Choose the Application pool identity radio button the click OK
7. Select the Application Pools node from IIS manager tree on left and select the Application Pool name you noted down in step 3
8. Right click and select Advanced Settings
9. Expand the Process Model settings and choose ApplicationPoolIdentityfrom the "Built-in account" drop down list then click OK.
10. Click OK again to save and dismiss the Application Pool advanced settings page
11. Open an Administrator command line (right click on the CMD icon and select "Run As Administrator". It'll be somewhere on your start menu, probably under Accessories.

12. Run the following command:

    icacls <path_to_site> /grant "IIS APPPOOL\<app_pool_name>"(CI)(OI)(M)
    

    For example:

    icacls C:\inetpub\wwwroot\mysite\ /grant "IIS APPPOOL\DEFAULTAPPPOOL":(CI)(OI)(M)
    

Especially steps 5. & 6. are often overlooked and rarely mentioned on the web.

Webkit supports gradients in borders, and now accepts the gradient in the Mozilla format.

Firefox claims to support gradients in two ways:

1. Using border-image with border-image-source
2. Using border-right-colors (right/left/top/bottom)

IE9 has no support.

I believe this snippet will also be helpful in a situation where the dates comparison spans more than two entries.

static final int COMPARE_EARLIEST = 0;

static final int COMPARE_MOST_RECENT = 1;


public LocalDate getTargetDate(List<LocalDate> datesList, int comparatorType) { 
   LocalDate refDate = null;
   switch(comparatorType)
   {
       case COMPARE_EARLIEST:         
       //returns the most earliest of the date entries
          refDate = (LocalDate) datesList.stream().min(Comparator.comparing(item -> 
                      item.toDateTimeAtCurrentTime())).get();
          break;

       case COMPARE_MOST_RECENT:
          //returns the most recent of the date entries 
          refDate = (LocalDate) datesList.stream().max(Comparator.comparing(item -> 
                    item.toDateTimeAtCurrentTime())).get();
          break;
   }

   return refDate;
}

Many people have mentioned DecimalFormat. But you can also use printf if you have a recent version of Java:

System.out.printf("%1.2f", 3.14159D);

See the docs on the Formatter for more information about the printf format string.

If your post try to reach the following URL

mypage.php?id=1

you will have the POST data but also GET data.

The exit() and quit() built in functions do just what you want. No import of sys needed.

Alternatively, you can raise SystemExit, but you need to be careful not to catch it anywhere (which shouldn't happen as long as you specify the type of exception in all your try.. blocks).

LGPL / FOSS iTextSharp 4.x

var pdfReader = new PdfReader(path); //other filestream etc
byte[] pageContent = _pdfReader .GetPageContent(pageNum); //not zero based
byte[] utf8 = Encoding.Convert(Encoding.Default, Encoding.UTF8, pageContent);
string textFromPage = Encoding.UTF8.GetString(utf8);

None of the other answers were useful to me, they all seem to target the AGPL v5 of iTextSharp. I could never find any reference to SimpleTextExtractionStrategy or LocationTextExtractionStrategy in the FOSS version.

Something else that might be very useful in conjunction with this:

const string PdfTableFormat = @"\(.*\)Tj";
Regex PdfTableRegex = new Regex(PdfTableFormat, RegexOptions.Compiled);

List<string> ExtractPdfContent(string rawPdfContent)
{
    var matches = PdfTableRegex.Matches(rawPdfContent);

    var list = matches.Cast<Match>()
        .Select(m => m.Value
            .Substring(1) //remove leading (
            .Remove(m.Value.Length - 4) //remove trailing )Tj
            .Replace(@"\)", ")") //unencode parens
            .Replace(@"\(", "(")
            .Trim()
        )
        .ToList();
    return list;
}

This will extract the text-only data from the PDF if the text displayed is Foo(bar) it will be encoded in the PDF as (Foo\(bar\))Tj, this method would return Foo(bar) as expected. This method will strip out lots of additional information such as location coordinates from the raw pdf content.

To get the value of a pointer, just de-reference the pointer.

int *ptr;
int value;
*ptr = 9;

value = *ptr;

value is now 9.

I suggest you read more about pointers, this is their base functionality.

You should never be writing code that looks like this:

private void DoGUISwitch() {
    if (object1.InvokeRequired) {
        object1.Invoke(new MethodInvoker(() => { DoGUISwitch(); }));
    } else {
        object1.Visible = true;
        object2.Visible = false;
    }
}

If you do have code that looks like this then your application is not thread-safe. It means that you have code which is already calling DoGUISwitch() from a different thread. It's too late to be checking to see if it's in a different thread. InvokeRequire must be called BEFORE you make a call to DoGUISwitch. You should not access any method or property from a different thread.

Reference: Control.InvokeRequired Property where you can read the following:

In addition to the InvokeRequired property, there are four methods on a control that are thread safe to call: Invoke, BeginInvoke, EndInvoke and CreateGraphics if the handle for the control has already been created.

In a single CPU architecture there's no problem, but in a multi-CPU architecture you can cause part of the UI thread to be assigned to the processor where the calling code was running...and if that processor is different from where the UI thread was running then when the calling thread ends Windows will think that the UI thread has ended and will kill the application process i.e. your application will exit without error.

I can offer you a jquery solution

add this in your <head></head> tag

<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.2.min.js"></script>

add this after </ul>

 <script> $('ul li:first').remove(); </script> 

You can use a Hashtable with each character as the key and the total count becomes the value.

Hashtable<Character,Integer> table = new Hashtable<Character,Integer>();
String str = "aasjjikkk";
for( c in str ) {
    if( table.get(c) == null )
        table.put(c,1);
    else
        table.put(c,table.get(c) + 1);
}

for( elem in table ) {
    println "elem:" + elem;
}

One way:

SELECT DISTINCT sc.StoreId
FROM StoreClients sc
WHERE NOT EXISTS(
    SELECT * FROM StoreClients sc2 
    WHERE sc2.StoreId = sc.StoreId AND sc2.ClientId = 5)

to complete of Pit answer and for better perfromance : get all in one query and use NextResult method.

using (var sqlCon = new SqlConnection("Server=127.0.0.1;Database=MyDb;User Id=Me;Password=glop;"))
{
    sqlCon.Open();
    var com = sqlCon.CreateCommand();
    com.CommandText = "select * from BigTable;select @@ROWCOUNT;";
    using (var reader = com.ExecuteReader())
    {
        while(reader.read()){
            //iterate code
        }
        int totalRow = 0 ;
        reader.NextResult(); // 
        if(reader.read()){
            totalRow = (int)reader[0];
        }
    }
    sqlCon.Close();
}

According to SolrQuerySyntax, you can use q=-id:[* TO *].

You can scroll to the element by using javascript through the execute_javascript method. For example here is how I do it using SeleniumLibrary on Robot Framework:

web_element = self.selib.find_element(locator)
self.selib.execute_javascript(
    "ARGUMENTS",
    web_element,
    "JAVASCRIPT",
    'arguments[0].scrollIntoView({behavior: "instant", block: "start", inline: "start"});'
)

$('#google').attr('onclick') + ""

However, Firebug shows that this returns a function 'onclick'. You can call the function later on using the following approach:

(new Function ($('#google').attr('onclick') + ';onclick();'))()

... or use a RegEx to strip the function and get only the statements within it.

I know the answers were correct at the time of asking the question - but since people (like me this minute) still happen to find them wondering why their WildFly 10 was behaving differently, I'd like to give an update for the current Hibernate 5.x version:

In the Hibernate 5.2 User Guide it is stated in chapter 11.2. Applying fetch strategies:

The Hibernate recommendation is to statically mark all associations lazy and to use dynamic fetching strategies for eagerness. This is unfortunately at odds with the JPA specification which defines that all one-to-one and many-to-one associations should be eagerly fetched by default. Hibernate, as a JPA provider, honors that default.

So Hibernate as well behaves like Ashish Agarwal stated above for JPA:

OneToMany: LAZY
ManyToOne: EAGER
ManyToMany: LAZY
OneToOne: EAGER

(see JPA 2.1 Spec)

string does not name a type. The class in the string header is called std::string.

Please do not put using namespace std in a header file, it pollutes the global namespace for all users of that header. See also "Why is 'using namespace std;' considered a bad practice in C++?"

Your class should look like this:

#include <string>

class Game
{
    private:
        std::string white;
        std::string black;
        std::string title;
    public:
        Game(std::istream&, std::ostream&);
        void display(colour, short);
};

Small And Better One

var i = 0;
$("#container > option").each(function(){ 
    if($(this).val().length > i) {
        i = $(this).val().length;

        console.log(i);
        console.log($(this).val());
    }
});

The solution that worked for me personally was:

in the build.gradle

defaultConfig {
        multiDexEnabled true
    }

 dexOptions {
        javaMaxHeapSize "4g"
    }

.clearfix:before, .clearfix:after, .container:before, .container:after, .container-fluid:before, .container-fluid:after, .row:before, .row:after, .form-horizontal .form-group:before, .form-horizontal .form-group:after, .btn-toolbar:before, .btn-toolbar:after, .btn-group-vertical > .btn-group:before, .btn-group-vertical > .btn-group:after, .nav:before, .nav:after, .navbar:before, .navbar:after, .navbar-header:before, .navbar-header:after, .navbar-collapse:before, .navbar-collapse:after, .pager:before, .pager:after, .panel-body:before, .panel-body:after, .modal-footer:before, .modal-footer:after {
    content: " ";
    display: table-cell;
}

ul.nav {
    float: none;
    margin-bottom: 0;
    margin-left: auto;
    margin-right: auto;
    margin-top: 0;
    width: 240px;

Map default.aspx as HttpHandler route and redirect to CreateThings.aspx from within the HttpHandler.

<add verb="GET" path="default.aspx" type="RedirectHandler"/>

Make sure Default.aspx does not exists physically at your application root. If it exists physically the HttpHandler will not be given any chance to execute. Physical file overrides HttpHandler mapping.

Moreover you can re-use this for pages other than default.aspx.

<add verb="GET" path="index.aspx" type="RedirectHandler"/>

setRetaininstance is only useful when your activity is destroyed and recreated due to a configuration change because the instances are saved during a call to onRetainNonConfigurationInstance. That is, if you rotate the device, the retained fragments will remain there(they're not destroyed and recreated.) but when the runtime kills the activity to reclaim resources, nothing is left. When you press back button and exit the activity, everything is destroyed.

Usually I use this function to saved orientation changing Time.Say I have download a bunch of Bitmaps from server and each one is 1MB, when the user accidentally rotate his device, I certainly don't want to do all the download work again.So I create a Fragment holding my bitmaps and add it to the manager and call setRetainInstance,all the Bitmaps are still there even if the screen orientation changes.

A cute piece of numerical weirdness may be observed if one converts 9999999.4999999999 to a float and back to a double. The result is reported as 10000000, even though that value is obviously closer to 9999999, and even though 9999999.499999999 correctly rounds to 9999999.

In my case on macOS I solved it with:

brew link libtool

If the time is 11:03, then the accepted answer will print 11:3.

You could zero-pad the minutes:

"Created at {:d}:{:02d}".format(tdate.hour, tdate.minute)

Or go another way and use tdate.time() and only take the hour/minute part:

str(tdate.time())[0:5]

Read the Request.Form NameValueCollection and process your logic accordingly:

NameValueCollection nvc = Request.Form;
string userName, password;
if (!string.IsNullOrEmpty(nvc["txtUserName"]))
{
  userName = nvc["txtUserName"];
}

if (!string.IsNullOrEmpty(nvc["txtPassword"]))
{
  password = nvc["txtPassword"];
}

//Process login
CheckLogin(userName, password);

... where "txtUserName" and "txtPassword" are the Names of the controls on the posting page.

You can't rely on window.open because browsers may have different policies. I had the same issue and I used the code below instead.

let a = document.createElement("a");
document.body.appendChild(a);
a.style = "display: none";
a.href = <your_url>;
a.download = <your_fileName>;
a.click();
document.body.removeChild(a);

Have you tried jQuery.contents() ?

In Python, how can I parse a numeric string like "545.2222" to its corresponding float value, 542.2222? Or parse the string "31" to an integer, 31? I just want to know how to parse a float string to a float, and (separately) an int string to an int.

It's good that you ask to do these separately. If you're mixing them, you may be setting yourself up for problems later. The simple answer is:

"545.2222" to float:

>>> float("545.2222")
545.2222

"31" to an integer:

>>> int("31")
31

Other conversions, ints to and from strings and literals:

Conversions from various bases, and you should know the base in advance (10 is the default). Note you can prefix them with what Python expects for its literals (see below) or remove the prefix:

>>> int("0b11111", 2)
31
>>> int("11111", 2)
31
>>> int('0o37', 8)
31
>>> int('37', 8)
31
>>> int('0x1f', 16)
31
>>> int('1f', 16)
31

If you don't know the base in advance, but you do know they will have the correct prefix, Python can infer this for you if you pass 0 as the base:

>>> int("0b11111", 0)
31
>>> int('0o37', 0)
31
>>> int('0x1f', 0)
31

Non-Decimal (i.e. Integer) Literals from other Bases

If your motivation is to have your own code clearly represent hard-coded specific values, however, you may not need to convert from the bases - you can let Python do it for you automatically with the correct syntax.

You can use the apropos prefixes to get automatic conversion to integers with the following literals. These are valid for Python 2 and 3:

Binary, prefix 0b

>>> 0b11111
31

Octal, prefix 0o

>>> 0o37
31

Hexadecimal, prefix 0x

>>> 0x1f
31

This can be useful when describing binary flags, file permissions in code, or hex values for colors - for example, note no quotes:

>>> 0b10101 # binary flags
21
>>> 0o755 # read, write, execute perms for owner, read & ex for group & others
493
>>> 0xffffff # the color, white, max values for red, green, and blue
16777215

Making ambiguous Python 2 octals compatible with Python 3

If you see an integer that starts with a 0, in Python 2, this is (deprecated) octal syntax.

>>> 037
31

It is bad because it looks like the value should be 37. So in Python 3, it now raises a SyntaxError:

>>> 037
  File "<stdin>", line 1
    037
      ^
SyntaxError: invalid token

Convert your Python 2 octals to octals that work in both 2 and 3 with the 0o prefix:

>>> 0o37
31

We found a quick-and-dirty cross browser implementation of ours that may do the trick for most simple cases with a minimal implementation:

window.onReady = function onReady(fn){
    document.body ? fn() : setTimeout(function(){ onReady(fn);},50);
};

Bootstrap does not document the media queries very well. Those variables of @screen-sm, @screen-md, @screen-lg are actually referring to LESS variables and not simple CSS.

When you customize Bootstrap you can change the media query breakpoints and when it compiles the @screen-xx variables are changed to whatever pixel width you defined as screen-xx. This is how a framework like this can be coded once and then customized by the end user to fit their needs.

A similar question on here that might provide more clarity: Bootstrap 3.0 Media queries

In your CSS, you will still have to use traditional media queries to override or add to what Bootstrap is doing.

In regards to your second question, that is not a typo. Once the screen goes below 768px the framework becomes completely fluid and resizes at any device width, removing the need for breakpoints. The breakpoint at 480px exists because there are specific changes that occur to the layout for mobile optimization.

To see this in action, go to this example on their site (http://getbootstrap.com/examples/navbar-fixed-top/), and resize your window to see how it treats the design after 768px.

From now on is better to use the .prop() function instead of the .attr() one.

Here the jQuery documentation:

As of jQuery 1.6, the .attr() method returns undefined for attributes that have not been set. In addition, .attr() should not be used on plain objects, arrays, the window, or the document. To retrieve and change DOM properties, use the .prop() method.

var div1Class = $('#div1').prop('class');

Whenever the Python interpreter reads a source file, it does two things:

• it sets a few special variables like __name__, and then

• it executes all of the code found in the file.

Let's see how this works and how it relates to your question about the __name__ checks we always see in Python scripts.

Code Sample

Let's use a slightly different code sample to explore how imports and scripts work. Suppose the following is in a file called foo.py.

# Suppose this is foo.py.

print("before import")
import math

print("before functionA")
def functionA():
    print("Function A")

print("before functionB")
def functionB():
    print("Function B {}".format(math.sqrt(100)))

print("before __name__ guard")
if __name__ == '__main__':
    functionA()
    functionB()
print("after __name__ guard")

Special Variables

When the Python interpreter reads a source file, it first defines a few special variables. In this case, we care about the __name__ variable.

When Your Module Is the Main Program

If you are running your module (the source file) as the main program, e.g.

python foo.py

the interpreter will assign the hard-coded string "__main__" to the __name__ variable, i.e.

# It's as if the interpreter inserts this at the top
# of your module when run as the main program.
__name__ = "__main__" 

When Your Module Is Imported By Another

On the other hand, suppose some other module is the main program and it imports your module. This means there's a statement like this in the main program, or in some other module the main program imports:

# Suppose this is in some other main program.
import foo

The interpreter will search for your foo.py file (along with searching for a few other variants), and prior to executing that module, it will assign the name "foo" from the import statement to the __name__ variable, i.e.

# It's as if the interpreter inserts this at the top
# of your module when it's imported from another module.
__name__ = "foo"

Executing the Module's Code

After the special variables are set up, the interpreter executes all the code in the module, one statement at a time. You may want to open another window on the side with the code sample so you can follow along with this explanation.

Always

1. It prints the string "before import" (without quotes).

2. It loads the math module and assigns it to a variable called math. This is equivalent to replacing import math with the following (note that __import__ is a low-level function in Python that takes a string and triggers the actual import):

# Find and load a module given its string name, "math",
# then assign it to a local variable called math.
math = __import__("math")

3. It prints the string "before functionA".

4. It executes the def block, creating a function object, then assigning that function object to a variable called functionA.

5. It prints the string "before functionB".

6. It executes the second def block, creating another function object, then assigning it to a variable called functionB.

7. It prints the string "before __name__ guard".

Only When Your Module Is the Main Program

8. If your module is the main program, then it will see that __name__ was indeed set to "__main__" and it calls the two functions, printing the strings "Function A" and "Function B 10.0".

Only When Your Module Is Imported by Another

8. (instead) If your module is not the main program but was imported by another one, then __name__ will be "foo", not "__main__", and it'll skip the body of the if statement.

Always

9. It will print the string "after __name__ guard" in both situations.

Summary

In summary, here's what'd be printed in the two cases:

# What gets printed if foo is the main program
before import
before functionA
before functionB
before __name__ guard
Function A
Function B 10.0
after __name__ guard

# What gets printed if foo is imported as a regular module
before import
before functionA
before functionB
before __name__ guard
after __name__ guard

Why Does It Work This Way?

You might naturally wonder why anybody would want this. Well, sometimes you want to write a .py file that can be both used by other programs and/or modules as a module, and can also be run as the main program itself. Examples:

• Your module is a library, but you want to have a script mode where it runs some unit tests or a demo.

• Your module is only used as a main program, but it has some unit tests, and the testing framework works by importing .py files like your script and running special test functions. You don't want it to try running the script just because it's importing the module.

• Your module is mostly used as a main program, but it also provides a programmer-friendly API for advanced users.

Beyond those examples, it's elegant that running a script in Python is just setting up a few magic variables and importing the script. "Running" the script is a side effect of importing the script's module.

Food for Thought

• Question: Can I have multiple __name__ checking blocks? Answer: it's strange to do so, but the language won't stop you.

• Suppose the following is in foo2.py. What happens if you say python foo2.py on the command-line? Why?

# Suppose this is foo2.py.
import os, sys; sys.path.insert(0, os.path.dirname(__file__)) # needed for some interpreters

def functionA():
    print("a1")
    from foo2 import functionB
    print("a2")
    functionB()
    print("a3")

def functionB():
    print("b")

print("t1")
if __name__ == "__main__":
    print("m1")
    functionA()
    print("m2")
print("t2")
      

• Now, figure out what will happen if you remove the __name__ check in foo3.py:

# Suppose this is foo3.py.
import os, sys; sys.path.insert(0, os.path.dirname(__file__)) # needed for some interpreters

def functionA():
    print("a1")
    from foo3 import functionB
    print("a2")
    functionB()
    print("a3")

def functionB():
    print("b")

print("t1")
print("m1")
functionA()
print("m2")
print("t2")

• What will this do when used as a script? When imported as a module?

# Suppose this is in foo4.py
__name__ = "__main__"

def bar():
    print("bar")
    
print("before __name__ guard")
if __name__ == "__main__":
    bar()
print("after __name__ guard")

A simple path global variable across each recursive call does the trick for me !

var object = {
  aProperty: {
    aSetting1: 1,
    aSetting2: 2,
    aSetting3: 3,
    aSetting4: 4,
    aSetting5: 5
  },
  bProperty: {
    bSetting1: {
      bPropertySubSetting: true
    },
    bSetting2: "bString"
  },
  cProperty: {
    cSetting: "cString"
  }
}

function iterate(obj, path = []) {
  for (var property in obj) {
    if (obj.hasOwnProperty(property)) {
      if (typeof obj[property] == "object") {
        let curpath = [...path, property];
        iterate(obj[property], curpath);
      } else {
        console.log(path.join('.') + '.' + property + "   " + obj[property]);
        $('#output').append($("<div/>").text(path.join('.') + '.' + property))
      }
    }
  }
}

iterate(object);

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.1/jquery.min.js"></script>
<div id='output'></div>

Meanwhile, another reason : accidentally deleted the .config file caused the same error message appears:

"Service on local computer started and then stopped. some services stop automatically..."

Matplotlib uses a dictionary from its colors.py module.

To print the names use:

# python2:

import matplotlib
for name, hex in matplotlib.colors.cnames.iteritems():
    print(name, hex)

# python3:

import matplotlib
for name, hex in matplotlib.colors.cnames.items():
    print(name, hex)

    pos = (x / x_count, y / y_count)
    ax.add_patch(patches.Rectangle(pos, w, h, color=c))
    ax.annotate(c, xy=pos)
    if y >= y_count-1:
        x += 1
        y = 0
    else:
        y += 1

plt.show()

Ok, so the answer was derived from some other posts about this problem and it is:

If your ViewData contains a SelectList with the same name as your DropDownList i.e. "submarket_0", the Html helper will automatically populate your DropDownList with that data if you don't specify the 2nd parameter which in this case is the source SelectList.

What happened with my error was:

Because the table containing the drop down lists was in a partial view and the ViewData had been changed and no longer contained the SelectList I had referenced, the HtmlHelper (instead of throwing an error) tried to find the SelectList called "submarket_0" in the ViewData (GRRRR!!!) which it STILL couldnt find, and then threw an error on that :)

Please correct me if im wrong

If you don't want to change to numeric you can try this.

You can create script /etc/cron.hourly/php and put there:

#!/bin/bash

max=24
tmpdir=/tmp

nice find ${tmpdir} -type f -name 'sess_*' -mmin +${max} -delete

Then make the script executable (chmod +x).

Now every hour will be deleted all session files with data modified more than 24 minutes ago.

package com.mycompany;

import javax.validation.constraints.Min;

public class Car {

    @NotNull
    private String manufacturer;

    @NotNull
    @Size(min = 2, max = 14)
    private String licensePlate;

    @Min(2)
    private int seatCount;

    public Car(String manufacturer, String licencePlate, int seatCount) {
        this.manufacturer = manufacturer;
        this.licensePlate = licencePlate;
        this.seatCount = seatCount;
    }

    //getters and setters ...
}

@NotNull, @Size and @Min are so-called constraint annotations, that we use to declare constraints, which shall be applied to the fields of a Car instance:

manufacturer shall never be null

licensePlate shall never be null and must be between 2 and 14 characters long

seatCount shall be at least 2.

I managed to find a solution, but not a great one as it requires using AsEnumerable() which is going to return all results from the DB, fortunately I only have 1k records in the table so it isn't really noticable, but here goes.

var users = from u in (from u in ctx.Users
                       where u.Mod_Status != "D"
                       select u).AsEnumerable()
            where ar.All(n => u.FullName.IndexOf(n,
                        StringComparison.InvariantCultureIgnoreCase) >= 0)
            select u;

My original post follows:

How do you do the reverse? I want to do something like the following in entity framework.

string[] search = new string[] { "John", "Doe" };
var users = from u in ctx.Users
            from s in search
           where u.FullName.Contains(s)
          select u;

What I want is to find all users where their FullName contains all of the elements in `search'. I've tried a number of different ways, all of which haven't been working for me.

I've also tried

var users = from u in ctx.Users select u;
foreach (string s in search) {
    users = users.Where(u => u.FullName.Contains(s));
}

This version only finds those that contain the last element in the search array.

If you truly just want to just "download" the folder and not "clone" it (for development), the easiest way to simply get a copy of the most recent version of the repository (and therefore a folder/file within it), without needing to clone the whole repo or even install git in the first place, is to download a zip archive (for any repo, fork, branch, commit, etc.) by going to the desired repository/fork/branch/commit on GitHub (e.g. http(s)://github.com/<user>/<repo>/commit/<Sha1> for a copy of the files as they were after a specific commit) and selecting the Downloads button near the upper-right.

This archive format contains none of the git-repo magic, just the tracked files themselves (and perhaps a few .gitignore files if they were tracked, but you can ignore those :p) - that means that if the code changes and you want to stay on top, you'll have to manually re-download it, and it also means you won't be able to use it as a git repository...

Not sure if that's what you're looking for in this case (again, "download"/view vs "clone"/develop), but it can be useful nonetheless...

<select id="ddlvalue" name="ddlvaluename">
<option value='0' disabled selected>Select Value</option>
<option value='1' >Value 1</option>
<option value='2' >Value 2</option>
</select>

<input type="submit" id="btn_submit" value="click me"/>



<script>
$('#btn_submit').on('click',function(){
      $('#ddlvalue').val(0);
});
</script>

this worked for me: Do not occupy large files, distribute in several small ones you create file Temp, delete file A and then rename file Temp to A.

import os
import json

def Server():
    i = 0
    while i == 0:
        try:        
                with open(File_Temp, "w") as file:
                    json.dump(DATA, file, indent=2)
                if os.path.exists(File_A):
                    os.remove(File_A)
                os.rename(File_Temp, File_A)
                i = 1
        except OSError as e:
                print ("file locked: " ,str(e))
                time.sleep(1)
            
            
def Clients():
    i = 0
    while i == 0:
        try:
            if os.path.exists(File_A):
                with open(File_A,"r") as file:
                    DATA_Temp = file.read()
            DATA = json.loads(DATA_Temp)
            i = 1
        except OSError as e:
            print (str(e))
            time.sleep(1)

Normally, in GIT to clear all your modifications & new files the following 2 commands should work very nicely (be CAREFUL, this will delete all your new files+folders you may have created & will restore all your modified files to the state of your current commit):

$ git clean --force -d
$ git checkout -- .

Maybe a better option sometimes is just doing "git stash push" with optional message, like so:

$ git stash push -m "not sure if i will need this later"

This will also clear all your new and modified files, but you'll have all of them stashed in case you want to restore them. Stash in GIT carries from branch to branch, so you can restore them in a different branch, if you wish to.

As a side note, in case you have already staged some newly added files and want to get rid of them, this should do the trick:

$ git reset --hard

If all of the above doesn't work for you, read below what worked for me a while ago:

I ran into this problem few times before. I'm currently developing on Windows 10 machine provided by my employer. Today, this particular git behavior was caused by me creating a new branch from my "develop" branch. For some reason, after I switched back to "develop" branch, some seemingly random files persisted and were showing up as "modified" in "git status".

Also, at that point I couldn't checkout another branch, so I was stuck on my "develop" branch.

This is what I did:

$ git log

I noticed that the new branch I created from "develop" earlier today was showing in the first "commit" message, being referenced at the end "HEAD -> develop, origin/develop, origin/HEAD, The-branch-i-created-earlier-today".

Since I didn't really need it, I deleted it:

$ git branch -d The-branch-i-created-earlier-today

The changed files were still showing up, so I did:

$ git stash

This solved my problem:

$ git status
On branch develop
Your branch is up to date with 'origin/develop'.

nothing to commit, working tree clean

Of course $ git stash list will show stashed changes, and since I had few and didn't need any of my stashes, I did $ git stash clear to DELETE ALL STASHES.

NOTE: I haven't tried doing what someone suggested here before me:

$ git rm --cached -r .
$ git reset --hard

This may have worked as well, I'll be sure to try it next time I run into this problem.

erlswf is an opensource project written in erlang for decompiling .swf files.

Here's the site: https://github.com/bef/erlswf

Perhaps get the size of the string and loop through each character and call isDigit() on each character. If it is a digit, then add it to a string that only collects the numbers before calling Integer.parseInt().

Something like:

    String something = "423e";
    int length = something.length();
    String result = "";
    for (int i = 0; i < length; i++) {
        Character character = something.charAt(i);
        if (Character.isDigit(character)) {
            result += character;
        }
    }
    System.out.println("result is: " + result);

Hopefully this is self explanatory enough. Use the comments in the code to help understand what is happening. Pass a single cell to this function. The value of that cell will be the base file name. If the cell contains "AwesomeData" then we will try and create a file in the current users desktop called AwesomeData.pdf. If that already exists then try AwesomeData2.pdf and so on. In your code you could just replace the lines filename = Application..... with filename = GetFileName(Range("A1"))

Function GetFileName(rngNamedCell As Range) As String
    Dim strSaveDirectory As String: strSaveDirectory = ""
    Dim strFileName As String: strFileName = ""
    Dim strTestPath As String: strTestPath = ""
    Dim strFileBaseName As String: strFileBaseName = ""
    Dim strFilePath As String: strFilePath = ""
    Dim intFileCounterIndex As Integer: intFileCounterIndex = 1

    ' Get the users desktop directory.
    strSaveDirectory = Environ("USERPROFILE") & "\Desktop\"
    Debug.Print "Saving to: " & strSaveDirectory

    ' Base file name
    strFileBaseName = Trim(rngNamedCell.Value)
    Debug.Print "File Name will contain: " & strFileBaseName

    ' Loop until we find a free file number
    Do
        If intFileCounterIndex > 1 Then
            ' Build test path base on current counter exists.
            strTestPath = strSaveDirectory & strFileBaseName & Trim(Str(intFileCounterIndex)) & ".pdf"
        Else
            ' Build test path base just on base name to see if it exists.
            strTestPath = strSaveDirectory & strFileBaseName & ".pdf"
        End If

        If (Dir(strTestPath) = "") Then
            ' This file path does not currently exist. Use that.
            strFileName = strTestPath
        Else
            ' Increase the counter as we have not found a free file yet.
            intFileCounterIndex = intFileCounterIndex + 1
        End If

    Loop Until strFileName <> ""

    ' Found useable filename
    Debug.Print "Free file name: " & strFileName
    GetFileName = strFileName

End Function

The debug lines will help you figure out what is happening if you need to step through the code. Remove them as you see fit. I went a little crazy with the variables but it was to make this as clear as possible.

In Action

My cell O1 contained the string "FileName" without the quotes. Used this sub to call my function and it saved a file.

Sub Testing()
    Dim filename As String: filename = GetFileName(Range("o1"))

    ActiveWorkbook.Worksheets("Sheet1").Range("A1:N24").ExportAsFixedFormat Type:=xlTypePDF, _
                                              filename:=filename, _
                                              Quality:=xlQualityStandard, _
                                              IncludeDocProperties:=True, _
                                              IgnorePrintAreas:=False, _
                                              OpenAfterPublish:=False
End Sub

Where is your code located in reference to everything else? Perhaps you need to make a module if you have not already and move your existing code into there.

use this.getClass().getName() to get packageName.className and use this.getClass().getSimpleName() to get only class name

This never gonna work, you can't stringify your FormData object.

You should do this:

this.uploadFileToUrl = function(file, title, text, uploadUrl){
   var fd = new FormData();
   fd.append('title', title);
   fd.append('text', text);
   fd.append('file', file);

     $http.post(uploadUrl, obj, {
       transformRequest: angular.identity,
       headers: {'Content-Type': undefined}
     })
  .success(function(){
    blockUI.stop();
  })
  .error(function(error){
    toaster.pop('error', 'Errore', error);
  });
}

Firstly, it probably depends which version of Solaris you're running, but also what hardware you have.

On SPARC at least, you have psrinfo to show you processor information, which run on its own will show you the number of CPUs the machine sees. psrinfo -p shows you the number of physical processors installed. From that you can deduce the number of threads/cores per physical processors.

prtdiag will display a fair bit of info about the hardware in your machine. It looks like on a V240 you do get memory channel info from prtdiag, but you don't on a T2000. I guess that's an architecture issue between UltraSPARC IIIi and UltraSPARC T1.

It is not possible to kill the session variable, when the machine unexpectly shutdown due to power failure. It is only possible when the user is idle for a long time or it is properly logout.

You asked if it is possible to change the circular dependency checking in those slf4j classes.

The simple answer is no.

• It is unconditional ... as implemented.
• It is implemented in a static initializer block ... so you can't override the implementation, and you can't stop it happening.

So the only way to change this would be to download the source code, modify the core classes to "fix" them, build and use them. That is probably a bad idea (in general) and probably not solution in this case; i.e. you risk triggering the stack overflow problem that the message warns about.

Reference:

• The source code.

The real solution (as you identified in your Answer) is to use the right JARs. My understanding is that the circularity that was detected is real and potentially problematic ... and unnecessary.

Just a thought, but Have you tried using application.undo

This will set the values back again. You can then simply read the original value. It should not be too difficult to store the new values first, so you change them back again if you like.

Just my 2 cents. This code combines two matrices or data.frames into one. If one data structure have lower number of rows then missing rows will be added with NA values.

combine.df <- function(x, y) {
    rows.x <- nrow(x)
    rows.y <- nrow(y)
    if (rows.x > rows.y) {
        diff <- rows.x - rows.y
        df.na <- matrix(NA, diff, ncol(y))
        colnames(df.na) <- colnames(y)
        cbind(x, rbind(y, df.na))
    } else {
        diff <- rows.y - rows.x
        df.na <- matrix(NA, diff, ncol(x))
        colnames(df.na) <- colnames(x)
        cbind(rbind(x, df.na), y)
    }
}

df1 <- data.frame(1:10, row.names = 1:10)
df2 <- data.frame(1:5, row.names = 10:14)
combine.df(df1, df2)

Guys use this code for adding nodes and childnodes for TreeView from C# code. *

KISS (Keep It Simple & Stupid :)*

protected void Button1_Click(object sender, EventArgs e)

{

        TreeNode a1 = new TreeNode("Apple");

        TreeNode b1 = new TreeNode("Banana");
        TreeNode a2 = new TreeNode("gree apple");
        TreeView2.Nodes.Add(a1);
        TreeView2.Nodes.Add(b1);
        a1.ChildNodes.Add(a2);

}

The best solution I found when dealing with Typescript classes and json objects: add a constructor in your Typescript class that takes the json data as parameter. In that constructor you extend your json object with jQuery, like this: $.extend( this, jsonData). $.extend allows keeping the javascript prototypes while adding the json object's properties.

export class Foo
{
    Name: string;
    getName(): string { return this.Name };

    constructor( jsonFoo: any )
    {
        $.extend( this, jsonFoo);
    }
}

In your ajax callback, translate your jsons in a your typescript object like this:

onNewFoo( jsonFoos : any[] )
{
  let receviedFoos = $.map( jsonFoos, (json) => { return new Foo( json ); } );

  // then call a method:
  let firstFooName = receviedFoos[0].GetName();
}

If you don't add the constructor, juste call in your ajax callback:

let newFoo = new Foo();
$.extend( newFoo, jsonData);
let name = newFoo.GetName()

...but the constructor will be useful if you want to convert the children json object too. See my detailed answer here.

If you want to do it in a tidyverse manner, try add_column from tibble, which allows you to specifiy where to place the new column with .before or .after parameter:

library(tibble)

df <- data.frame(b = c(1, 1, 1), c = c(2, 2, 2), d = c(3, 3, 3))
add_column(df, a = 0, .before = 1)

#   a b c d
# 1 0 1 2 3
# 2 0 1 2 3
# 3 0 1 2 3

As a further comment on https://stackoverflow.com/a/218037/2279200 - this may break, if the web app implicitely starts other ServletContextListener's, which may get called earlier and which already try to use log4j - in this case, the log4j configuration will be read and parsed already before the property determining the log root directory is set => the log files will appear somewhere below the current directory (the current directory when starting tomcat).

I could only think of following solution to this problem: - rename your log4j.properties (or logj4.xml) file to something which log4j will not automatically read. - In your context filter, after setting the property, call the DOM/PropertyConfigurator helper class to ensure that your log4j-.{xml,properties} is read - Reset the log4j configuration (IIRC there is a method to do that)

This is a bit brute force, but methinks it is the only way to make it watertight.

Instead of this goto mess, try using the ampersand & or double ampersand && (conditional to errorlevel 0) as command separators.

I fixed a script snippet with this trick, to summarize, I have three batch files, one which calls the other two after having found which letters the external backup drives have been assigned. I leave the first file on the primary external drive so the calls to its backup routine worked fine, but the calls to the second one required an active drive change. The code below shows how I fixed it:

for %%b in (d e f g h i j k l m n o p q r s t u v w x y z) DO (
if exist "%%b:\Backup.cmd" %%b: & CALL "%%b:\Backup.cmd"
)

In my case only flush() did not work. I had to use a clear() after flush().

public Object merge(final Object detachedInstance)
    {
        this.getHibernateTemplate().flush();
        this.getHibernateTemplate().clear();
        try
        {
            this.getHibernateTemplate().evict(detachedInstance);
        }
}

You can attach one and even more databases and work with it in the same way like using sqlite dbname.db

sqlite3
:
sqlite> attach "mydb.sqlite" as db1;

and u can see all attached databases with .databases

where in normal way the main is used for the command-line db

.databases
seq  name             file                                                      
---  ---------------  ----------------------------------------------------------

1    temp

If you write this yourself these are some of the points to keep in mind

Proper authentication between the device and the Sync Server

A sync protocol between the device and the server. It will usually go in 3 phases, authentication, data exchange, status exchange (which operations worked and which failed)

Pick your payload format. I suggest SyncML based XML mixed with JSON based format to represent the actual data. So SyncML for the protocol, and JSON for the actual data being exchanged. Using JSON Array while manipulating the data is always preferred as it is easy to access data using JSON Array.

Keeping track of data changes on both client and server. You can maintain a changelog of ids that change and pick them up during a sync session. Also, clear the changelog as the objects are successfully synchronized. You can also use a boolean variable to confirm the synchronization status, i.e. last time of sync. It will be helpful for end users to identify the time when last sync is done.

Need to have a way to communicate from the server to the device to start a sync session as data changes on the server. You can use C2DM or write your own persistent tcp based communication. The tcp approach is a lot seamless

A way to replicate data changes across multiple devices

And last but not the least, a way to detect and handle conflicts

Hope this helps as a good starting point.

Why not skip the string altogether :

SqlDateTime myDateTime = DateTime.Now;

Use DispatchGroups to achieve this. You can either get notified when the group's enter() and leave() calls are balanced:

func myFunction() {
    var a: Int?

    let group = DispatchGroup()
    group.enter()

    DispatchQueue.main.async {
        a = 1
        group.leave()
    }

    // does not wait. But the code in notify() gets run 
    // after enter() and leave() calls are balanced

    group.notify(queue: .main) {
        print(a)
    }
}

or you can wait:

func myFunction() {
    var a: Int?

    let group = DispatchGroup()
    group.enter()

    // avoid deadlocks by not using .main queue here
    DispatchQueue.global(attributes: .qosDefault).async {
        a = 1
        group.leave()
    }

    // wait ...
    group.wait()

    print(a) // you could also `return a` here
}

Note: group.wait() blocks the current queue (probably the main queue in your case), so you have to dispatch.async on another queue (like in the above sample code) to avoid a deadlock.

What is Stroke:

The BasicStroke class defines a basic set of rendering attributes for the outlines of graphics primitives, which are rendered with a Graphics2D object that has its Stroke attribute set to this BasicStroke.

https://docs.oracle.com/javase/7/docs/api/java/awt/BasicStroke.html

Note that the Stroke setting:

Graphics2D g2 = (Graphics2D) g;
g2.setStroke(new BasicStroke(10));

is setting the line width,since BasicStroke(float width):

Constructs a solid BasicStroke with the specified line width and with default values for the cap and join styles.

And, it also effects other methods like Graphics2D.drawLine(int x1, int y1, int x2, int y2) and Graphics2D.drawRect(int x, int y, int width, int height):

The methods of the Graphics2D interface that use the outline Shape returned by a Stroke object include draw and any other methods that are implemented in terms of that method, such as drawLine, drawRect, drawRoundRect, drawOval, drawArc, drawPolyline, and drawPolygon.

According to the documentation:

The WORKDIR instruction sets the working directory for any RUN, CMD, ENTRYPOINT, COPY and ADD instructions that follow it in the Dockerfile. If the WORKDIR doesn’t exist, it will be created even if it’s not used in any subsequent Dockerfile instruction.

Also, in the Docker best practices it recommends you to use it:

... you should use WORKDIR instead of proliferating instructions like RUN cd … && do-something, which are hard to read, troubleshoot, and maintain.

I would suggest to keep it.

I think you can refactor your Dockerfile to something like:

FROM node:latest
WORKDIR /usr/src/app
COPY package.json .
RUN npm install
COPY . ./
EXPOSE 3000
CMD [ “npm”, “start” ] 

var years = [];
for (i= 2015;i<=2030;i=i+1)
{
years.push({operator : i})
}

here array years is having values like

years[0]={operator:2015}
years[1]={operator:2016}

it continues like this.

In my case, it was because it didn't like that I left the minSDK and targeSdk in the manifest. Go figure.

I manually filled NAs by exporting the CSV then editing it and reimporting, as below.

Perhaps one of you experts might explain why this procedure worked so well (the first file had columns with data of types char, INT and num (floating point numbers)), which all became char type after STEP 1; but at the end of STEP 3 R correctly recognized the datatype of each column).

# STEP 1:
MainOptionFile <- read.csv("XLUopt_XLUstk_v3.csv",
                            header=T, stringsAsFactors=FALSE)
#... STEP 2:
TestFrame <- subset(MainOptionFile, str_locate(option_symbol,"120616P00034000") > 0)
write.csv(TestFrame, file = "TestFrame2.csv")
# ...
# STEP 3:
# I made various amendments to `TestFrame2.csv`, including replacing all missing data cells with appropriate numbers. I then read that amended data frame back into R as follows:    
XLU_34P_16Jun12 <- read.csv("TestFrame2_v2.csv",
                            header=T,stringsAsFactors=FALSE)

On arrival back in R, all columns had their correct measurement levels automatically recognized by R!

You have to shrink & backup the log a several times to get the log file to reduce in size, this is because the the log file pages cannot be re-organized as data files pages can be, only truncated. For a more detailed explanation check this out.

WARNING : Detaching the db & deleting the log file is dangerous! don't do this unless you'd like data loss

Yes, it does deserialize to List<>. No need to keep it in an array and wrap/encapsulate it in a list.

public class UserHolder
{
    private List<User> users = null;

    public UserHolder()
    {
    }

    [XmlElement("user")]
    public List<User> Users
    {
        get { return users; }
        set { users = value; }
    }
}

Deserializing code,

XmlSerializer xs = new XmlSerializer(typeof(UserHolder));
UserHolder uh = (UserHolder)xs.Deserialize(new StringReader(str));

Complete the following steps in Eclipse to get plugins for JavaScript files:

1. Open Eclipse -> Go to "Help" -> "Install New Software"
2. Select the repository for your version of Eclipse. I have Juno so I selected http://download.eclipse.org/releases/juno
3. Expand "Programming Languages" -> Check the box next to "JavaScript Development Tools"
4. Click "Next" -> "Next" -> Accept the Terms of the License Agreement -> "Finish"
5. Wait for the software to install, then restart Eclipse (by clicking "Yes" button at pop up window)
6. Once Eclipse has restarted, open "Window" -> "Preferences" -> Expand "General" and "Editors" -> Click "File Associations" -> Add ".js" to the "File types:" list, if it is not already there
7. In the same "File Associations" dialog, click "Add" in the "Associated editors:" section
8. Select "Internal editors" radio at the top
9. Select "JavaScript Viewer". Click "OK" -> "OK"

To add JavaScript Perspective: (Optional)
10. Go to "Window" -> "Open Perspective" -> "Other..."
11. Select "JavaScript". Click "OK"

To open .html or .js file with highlighted JavaScript syntax:
12. (Optional) Select JavaScript Perspective
13. Browse and Select .html or .js file in Script Explorer in [JavaScript Perspective] (Or Package Explorer [Java Perspective] Or PyDev Package Explorer [PyDev Perspective] Don't matter.)
14. Right-click on .html or .js file -> "Open With" -> "Other..."
15. Select "Internal editors"
16. Select "Java Script Editor". Click "OK" (see JavaScript syntax is now highlighted )

while it might not matter now here is a function which generate a float between 2 values.

#include <math.h>

float func_Uniform(float left, float right) {
    float randomNumber = sin(rand() * rand());
    return left + (right - left) * fabs(randomNumber);
}

I ended up doing this

typeof ($('#mySelector').data('events').click) == "object"

Besides being a bitwise complement operator, ~ can also help revert a boolean value, though it is not the conventional bool type here, rather you should use numpy.bool_.

This is explained in,

import numpy as np
assert ~np.True_ == np.False_

Reversing logical value can be useful sometimes, e.g., below ~ operator is used to cleanse your dataset and return you a column without NaN.

from numpy import NaN
import pandas as pd

matrix = pd.DataFrame([1,2,3,4,NaN], columns=['Number'], dtype='float64')
# Remove NaN in column 'Number'
matrix['Number'][~matrix['Number'].isnull()]

Intro:

Nested classes relate to other classes a little differently than outer classes. Taking Java as an example:

Non-static nested classes have access to other members of the enclosing class, even if they are declared private. Also, non-static nested classes require an instance of the parent class to be instantiated.

OuterClass outerObj = new OuterClass(arguments);
outerObj.InnerClass innerObj = outerObj.new InnerClass(arguments);

There are several compelling reasons for using them:

• It is a way of logically grouping classes that are only used in one place.

If a class is useful to only one other class, then it is logical to relate and embed it in that class and keep the two together.

• It increases encapsulation.

Consider two top-level classes, A and B, where B needs access to members of A that would otherwise be declared private. By hiding class B within class A, A's members can be declared private and B can access them. In addition, B itself can be hidden from the outside world.

• Nested classes can lead to more readable and maintainable code.

A nested class usually relates to it's parent class and together form a "package"

In PHP

You can have similar behavior in PHP without nested classes.

If all you want to achieve is structure/organization, as Package.OuterClass.InnerClass, PHP namespaces might sufice. You can even declare more than one namespace in the same file (although, due to standard autoloading features, that might not be advisable).

namespace;
class OuterClass {}

namespace OuterClass;
class InnerClass {}

If you desire to emulate other characteristics, such as member visibility, it takes a little more effort.

Defining the "package" class

namespace {

    class Package {

        /* protect constructor so that objects can't be instantiated from outside
         * Since all classes inherit from Package class, they can instantiate eachother
         * simulating protected InnerClasses
         */
        protected function __construct() {}

        /* This magic method is called everytime an inaccessible method is called 
         * (either by visibility contrains or it doesn't exist)
         * Here we are simulating shared protected methods across "package" classes
         * This method is inherited by all child classes of Package 
         */
        public function __call($method, $args) {

            //class name
            $class = get_class($this);

            /* we check if a method exists, if not we throw an exception 
             * similar to the default error
             */
            if (method_exists($this, $method)) {

                /* The method exists so now we want to know if the 
                 * caller is a child of our Package class. If not we throw an exception
                 * Note: This is a kind of a dirty way of finding out who's
                 * calling the method by using debug_backtrace and reflection 
                 */
                $trace = debug_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS, 3);
                if (isset($trace[2])) {
                    $ref = new ReflectionClass($trace[2]['class']);
                    if ($ref->isSubclassOf(__CLASS__)) {
                        return $this->$method($args);
                    }
                }
                throw new \Exception("Call to private method $class::$method()");
            } else {
                throw new \Exception("Call to undefined method $class::$method()");
            }
        }
    }
}

Use case

namespace Package {
    class MyParent extends \Package {
        public $publicChild;
        protected $protectedChild;

        public function __construct() {
            //instantiate public child inside parent
            $this->publicChild = new \Package\MyParent\PublicChild();
            //instantiate protected child inside parent
            $this->protectedChild = new \Package\MyParent\ProtectedChild();
        }

        public function test() {
            echo "Call from parent -> ";
            $this->publicChild->protectedMethod();
            $this->protectedChild->protectedMethod();

            echo "<br>Siblings<br>";
            $this->publicChild->callSibling($this->protectedChild);
        }
    }
}

namespace Package\MyParent
{
    class PublicChild extends \Package {
        //Makes the constructor public, hence callable from outside 
        public function __construct() {}
        protected function protectedMethod() {
            echo "I'm ".get_class($this)." protected method<br>";
        }

        protected function callSibling($sibling) {
            echo "Call from " . get_class($this) . " -> ";
            $sibling->protectedMethod();
        }
    }
    class ProtectedChild extends \Package { 
        protected function protectedMethod() {
            echo "I'm ".get_class($this)." protected method<br>";
        }

        protected function callSibling($sibling) {
            echo "Call from " . get_class($this) . " -> ";
            $sibling->protectedMethod();
        }
    }
}

Testing

$parent = new Package\MyParent();
$parent->test();
$pubChild = new Package\MyParent\PublicChild();//create new public child (possible)
$protChild = new Package\MyParent\ProtectedChild(); //create new protected child (ERROR)

Output:

Call from parent -> I'm Package protected method
I'm Package protected method

Siblings
Call from Package -> I'm Package protected method
Fatal error: Call to protected Package::__construct() from invalid context

NOTE:

I really don't think trying to emulate innerClasses in PHP is such a good idea. I think the code is less clean and readable. Also, there are probably other ways to achieve similar results using a well established pattern such as the Observer, Decorator ou COmposition Pattern. Sometimes, even simple inheritance is sufficient.

@Paul Cavacas, I had the same issue and I solved by setting the Input() decorator above the getter.

  @Input('allowDays')
  get in(): any {
    return this._allowDays;
  }

  //@Input('allowDays')
  // not working
  set in(val) {
    console.log('allowDays = '+val);
    this._allowDays = val;
  }

I recently published a jQuery plugin which allows you to make PHP function calls in various ways: https://github.com/Xaxis/jquery.php

Simple example usage:

// Both .end() and .data() return data to variables
var strLenA = P.strlen('some string').end();
var strLenB = P.strlen('another string').end();
var totalStrLen = strLenA + strLenB;
console.log( totalStrLen ); // 25

// .data Returns data in an array
var data1 = P.crypt("Some Crypt String").data();
console.log( data1 ); // ["$1$Tk1b01rk$shTKSqDslatUSRV3WdlnI/"]

In case anyone else ends up here with my issue with a DB First Entity Framework setup.

Long story short, I needed to overload the Entities constructor to accept a connection string, the reason being the ability to use Asp.Net Core dependency injection container pulling the connection string from appsettings.json, rather than magically getting it from the App.config file when calling the parameterless constructor.

I forgot to add the calls to initialize my DbSets in the new overload. So the auto-generated parameter-less constructor looked something like this:

    public MyEntities()
        : base("name=MyEntity")
    {
        Set1 = Set<MyDbSet1>();
        Set2 = Set<MyDbSet2>();
    }

And my new overload looked like this:

    public MyEntities(string connectionString)
        : base(connectionString)
    {
    }

The solution was to add those initializers that the auto-generated code takes care of, a simple missed step:

     public MyEntities(string connectionString)
        : base(connectionString)
    {
        Set1 = Set<MyDbSet1>();
        Set2 = Set<MyDbSet2>();
    }

This really threw me for a loop because some calls in our Respository that used the DbContext worked fine (the ones that didn't need those initialized DBSets), and the others throw the runtime error described in the OP.

You can pass program arguments on the command line and get them in your Java app like this:

public static void main(String[] args) {
  String pathToXml = args[0];
....
}

Alternatively you pass a system property by changing the command line to:

java -Dpath-to-xml=enwiki-20111007-pages-articles.xml -jar wiki2txt

and your main class to:

public static void main(String[] args) {
  String pathToXml = System.getProperty("path-to-xml");
....
}

If redirecting stdout works for your problem, Gringo Suave's answer is a good demonstration for how to do it.

To make it even easier, I made a version utilizing contextmanagers for a succinct generalized calling syntax using the with statement:

from contextlib import contextmanager
import sys

@contextmanager
def redirected_stdout(outstream):
    orig_stdout = sys.stdout
    try:
        sys.stdout = outstream
        yield
    finally:
        sys.stdout = orig_stdout

To use it, you just do the following (derived from Suave's example):

with open('out.txt', 'w') as outfile:
    with redirected_stdout(outfile):
        for i in range(2):
            print('i =', i)

It's useful for selectively redirecting print when a module uses it in a way you don't like. The only disadvantage (and this is the dealbreaker for many situations) is that it doesn't work if one wants multiple threads with different values of stdout, but that requires a better, more generalized method: indirect module access. You can see implementations of that in other answers to this question.

For those of you who have tried all the above mentioned methods including Windows system env. variables, .bashrc, .bashprofile, etc. AND can see the correct path in 'echo $PATH' ... I may have a solution for you.

suppress the errors using exec 2> /dev/null

My script runs fine but was throwing 'command not found' or 'No directory found' errors even though, as far as I can tell, the paths were flush. So, if you suppress those errors (might have to also add 'set +e'), than it works properly.

You just use jquery each() function ;

$(function() {
    $( ".selector_class_name" ).each(function(){
        $( this ).accordion({
          collapsible: true, 
          active:false,
          heightStyle: "content"
        });
    });
});

Run dos2unix or similar utility on it to remove the carriage returns (^M).

This message indicates that your file has dos-style lineendings:

-bash: /backup/backup.sh: /bin/bash^M: bad interpreter: No such file or directory 

Utilities like dos2unix will fix it:

 dos2unix <backup.bash >improved-backup.sh 

Or, if no such utility is installed, you can accomplish the same thing with translate:

tr -d "\015\032" <backup.bash >improved-backup.sh 

As for how those characters got there in the first place, @MadPhysicist had some good comments.

As others have mentioned the underlying dict is unordered. However there are OrderedDict objects in python. ( They're built in in recent pythons, or you can use this: http://code.activestate.com/recipes/576693/ ).

I believe that newer pythons json implementations correctly handle the built in OrderedDicts, but I'm not sure (and I don't have easy access to test).

Old pythons simplejson implementations dont handle the OrderedDict objects nicely .. and convert them to regular dicts before outputting them.. but you can overcome this by doing the following:

class OrderedJsonEncoder( simplejson.JSONEncoder ):
   def encode(self,o):
      if isinstance(o,OrderedDict.OrderedDict):
         return "{" + ",".join( [ self.encode(k)+":"+self.encode(v) for (k,v) in o.iteritems() ] ) + "}"
      else:
         return simplejson.JSONEncoder.encode(self, o)

now using this we get:

>>> import OrderedDict
>>> unordered={"id":123,"name":"a_name","timezone":"tz"}
>>> ordered = OrderedDict.OrderedDict( [("id",123), ("name","a_name"), ("timezone","tz")] )
>>> e = OrderedJsonEncoder()
>>> print e.encode( unordered )
{"timezone": "tz", "id": 123, "name": "a_name"}
>>> print e.encode( ordered )
{"id":123,"name":"a_name","timezone":"tz"}

Which is pretty much as desired.

Another alternative would be to specialise the encoder to directly use your row class, and then you'd not need any intermediate dict or UnorderedDict.

You want to do the check for undefined first. If you do it the other way round, it will generate an error if the array is undefined.

if (array === undefined || array.length == 0) {
    // array empty or does not exist
}

Update

This answer is getting a fair amount of attention, so I'd like to point out that my original answer, more than anything else, addressed the wrong order of the conditions being evaluated in the question. In this sense, it fails to address several scenarios, such as null values, other types of objects with a length property, etc. It is also not very idiomatic JavaScript.

The foolproof approach
Taking some inspiration from the comments, below is what I currently consider to be the foolproof way to check whether an array is empty or does not exist. It also takes into account that the variable might not refer to an array, but to some other type of object with a length property.

if (!Array.isArray(array) || !array.length) {
  // array does not exist, is not an array, or is empty
  // ? do not attempt to process array
}

To break it down:

1. Array.isArray(), unsurprisingly, checks whether its argument is an array. This weeds out values like null, undefined and anything else that is not an array.
   Note that this will also eliminate array-like objects, such as the arguments object and DOM NodeList objects. Depending on your situation, this might not be the behavior you're after.

2. The array.length condition checks whether the variable's length property evaluates to a truthy value. Because the previous condition already established that we are indeed dealing with an array, more strict comparisons like array.length != 0 or array.length !== 0 are not required here.

The pragmatic approach
In a lot of cases, the above might seem like overkill. Maybe you're using a higher order language like TypeScript that does most of the type-checking for you at compile-time, or you really don't care whether the object is actually an array, or just array-like.

In those cases, I tend to go for the following, more idiomatic JavaScript:

if (!array || !array.length) {
    // array or array.length are falsy
    // ? do not attempt to process array
}

Or, more frequently, its inverse:

if (array && array.length) {
    // array and array.length are truthy
    // ? probably OK to process array
}

With the introduction of the optional chaining operator (Elvis operator) in ECMAScript 2020, this can be shortened even further:

if (!array?.length) {
    // array or array.length are falsy
    // ? do not attempt to process array
}

Or the opposite:

if (array?.length) {
    // array and array.length are truthy
    // ? probably OK to process array
}

Oneliner using find, with automatic character set detection

The character encoding of all matching text files gets detected automatically and all matching text files are converted to utf-8 encoding:

$ find . -type f -iname *.txt -exec sh -c 'iconv -f $(file -bi "$1" |sed -e "s/.*[ ]charset=//") -t utf-8 -o converted "$1" && mv converted "$1"' -- {} \;

To perform these steps, a sub shell sh is used with -exec, running a one-liner with the -c flag, and passing the filename as the positional argument "$1" with -- {}. In between, the utf-8 output file is temporarily named converted.

Whereby file -bi means:

• -b, --brief Do not prepend filenames to output lines (brief mode).

• -i, --mime Causes the file command to output mime type strings rather than the more traditional human readable ones. Thus it may say for example text/plain; charset=us-ascii rather than ASCII text. The sed command cuts this to only us-ascii as is required by iconv.

The find command is very useful for such file management automation. Click here for more find galore.

Try changing the this.getElementsByTagName("td")[0]) line to read row.getElementsByTagName("td")[0];. That should capture the row reference in a closure, and it should work as expected.

Edit: The above is wrong, since row is a global variable -- as others have said, allocate a new variable and then use THAT in the closure.

.process-list:after{
    content: "\2191";
    position: absolute;
    top:50%;
    right:-8px;
    background-color: #ea1f41;
    width:35px;
    height: 35px;
    border:2px solid #ffffff;
    border-radius: 5px;
    color: #ffffff;
    z-index: 10000;
    -webkit-transform: rotate(50deg) translateY(-50%);
    -moz-transform: rotate(50deg) translateY(-50%);
    -ms-transform: rotate(50deg) translateY(-50%);
    -o-transform: rotate(50deg) translateY(-50%);
    transform: rotate(50deg) translateY(-50%);
}

you can check this code . i hope you will easily understand.

I Found that removing the references to Entity Framework and installing the latest version of Entity Framework from NuGet fixed the issue. It recreates all the required entries for you during install.

It happens because Build Tools revision 24.4.1 doesn't exist.

The latest version is 23.0.2.
These tools is included in the SDK package and installed in the <sdk>/build-tools/ directory.

Don't confuse the Android SDK Tools with SDK Build Tools.

Change in your build.gradle

android {
   buildToolsVersion "23.0.2"

There is a way to do this without installing putty on your Mac. You can easily convert your existing PPK file to a PEM file using PuTTYgen on Windows.

Launch PuTTYgen and then load the existing private key file using the Load button. From the "Conversions" menu select "Export OpenSSH key" and save the private key file with the .pem file extension.

Copy the PEM file to your Mac and set it to be read-only by your user:

chmod 400 <private-key-filename>.pem

Then you should be able to use ssh to connect to your remote server

ssh -i <private-key-filename>.pem username@hostname

I don't think this is your case, but I'll post it if it helps anyone. I had the same issue and the problem was that Node didn't respond at all (I had a condition that when failed didn't do anything - so no response) - So if increasing all your timeouts didn't solve it, make sure all scenarios get a response.

Found this on a different forum

If you're wondering why that leading zero is important, it's because permissions are set as an octal integer, and Python automagically treats any integer with a leading zero as octal. So os.chmod("file", 484) (in decimal) would give the same result.

What you are doing is passing 664 which in octal is 1230

In your case you would need

os.chmod("/tmp/test_file", 436)

[Update] Note, for Python 3 you have prefix with 0o (zero oh). E.G, 0o666

The previous answers were in the right track, but the complete answer for this is going to Disabling rules only for a group of files, there you'll find the documentation needed to disable/enable rules for certain folders (Because in some cases you don't want to ignore the whole thing, only disable certain rules). Example:

    "env": {},
    "extends": [],
    "parser": "",
    "plugins": [],
    "rules": {},
    "overrides": [
      {

Whenever you want to redirect, send the headers:

header("Location: http://www.example.com/");

Remember you cant send data to the client before that, though.

I know it's a bit late for this answer, but I've not seen anyone else put this.

Like Greg said, you want to use the Random class

Random rand = new Random();

but the difference I'm going to say is simple do this:

Color color = new Color(rand.nextInt(0xFFFFFF));

And it's as simple as that! no need to generate lots of different floats.

A visual for those that benefit from it.

After right-clicking the project name ("test" in this example), select "Add framework support" and check the "Maven" option.

if your text size is small, you should make the width of your text view to be "fill_parent". After that, you can set your TextView Gravity to center :

TextView textView = new TextView(this);
textView.setText(message);
textView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
textView.setGravity(Gravity.CENTER);

In bash version 4 associative arrays were introduced.

declare -A arr

arr["key1"]=val1

arr+=( ["key2"]=val2 ["key3"]=val3 )

The arr array now contains the three key value pairs. Bash is fairly limited what you can do with them though, no sorting or popping etc.

for key in ${!arr[@]}; do
    echo ${key} ${arr[${key}]}
done

Will loop over all key values and echo them out.

Note: Bash 4 does not come with Mac OS X because of its GPLv3 license; you have to download and install it. For more on that see here

Google recently added this comprehensive list of reference devices and resolutions, including new device types such as wearables and laptops:

https://design.google.com/devices/

This works for me with Python3 on Linux:

import tkinter as tk

# Create Tk window
root = tk.Tk()

# Add icon from GIF file where my GIF is called 'icon.gif' and
# is in the same directory as this .py file
root.tk.call('wm', 'iconphoto', root._w, tk.PhotoImage(file='icon.gif'))

Use lambda expression:

df[df.apply(lambda x: x['col1'] != x['col2'], axis = 1)]

Do you have an activity set up the be the launched activity when the application starts?

This is done in your Manifest.xml file, something like:

    <activity android:name=".Main" android:label="@string/app_name"
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

SELECT * from new WHERE date < DATE_ADD(now(),interval -1 day);

I haven't tried it but it looks like animateLayoutChanges should do what you're looking for. I see it in the ImageSwitcher class, I assume it's in the ViewSwitcher class as well?

It doesn't always need to be toolkit-dependent or one doesn't always need use the FontMetrics approach since it requires one to first obtain a graphics object which is absent in a web container or in a headless enviroment.

I have tested this in a web servlet and it does calculate the text width.

import java.awt.Font;
import java.awt.font.FontRenderContext;
import java.awt.geom.AffineTransform;

...

String text = "Hello World";
AffineTransform affinetransform = new AffineTransform();     
FontRenderContext frc = new FontRenderContext(affinetransform,true,true);     
Font font = new Font("Tahoma", Font.PLAIN, 12);
int textwidth = (int)(font.getStringBounds(text, frc).getWidth());
int textheight = (int)(font.getStringBounds(text, frc).getHeight());

Add the necessary values to these dimensions to create any required margin.

round(float("123.789"))

will give you an integer value, but a float type. With Python's duck typing, however, the actual type is usually not very relevant. This will also round the value, which you might not want. Replace 'round' with 'int' and you'll have it just truncated and an actual int. Like this:

int(float("123.789"))

But, again, actual 'type' is usually not that important.

len(yourdict.keys())

or just

len(yourdict)

If you like to count unique words in the file, you could just use set and do like

len(set(open(yourdictfile).read().split()))

df['variance'] = df.loc[:,['budget','actual']].sum(axis=1)

Well, wait a minute. I don't think the base tag deserves this bad reputation.

The nice thing about the base tag is that it enables you to do complex URL rewrites with less hassle.

Here's an example. You decide to move http://example.com/product/category/thisproduct to http://example.com/product/thisproduct. You change your .htaccess file to rewrite the first URL to the second URL.

With the base tag in place, you do your .htaccess rewrite and that's it. No problem. But without the base tag, all of your relative links will break.

URL rewrites are often necessary, because tweaking them can help your site's architecture and search engine visibility. True, you'll need workarounds for the "#" and '' problems that folks mentioned. But the base tag deserves a place in the toolkit.

This works for me.

void pause()
{
    cin.clear();
    cin.ignore(numeric_limits<streamsize>::max(), '\n');
    std::string dummy;
    std::cout << "Press any key to continue . . .";
    std::getline(std::cin, dummy);
}

char array[] = new String("Hi there").toCharArray();
for(char c : array)
    System.out.print(c + " ");

os.path.abspath(os.path.join(os.path.dirname( __file__ ), '..', 'templates'))

As far as where the templates folder should go, I don't know since Django 1.4 just came out and I haven't looked at it yet. You should probably ask another question on SE to solve that issue.

You can also use normpath to clean up the path, rather than abspath. However, in this situation, Django expects an absolute path rather than a relative path.

For cross platform compatability, use os.pardir instead of '..'.

sprintf: Writes formatted data to a character string in memory instead of stdout

Syntax of sprintf is:

#include <stdio.h>
int sprintf (char *string, const char *format
[,item [,item]…]);

Here,

String refers to the pointer to a buffer in memory where the data is to be written.

Format refers to pointer to a character string defining the format.

Each item is a variable or expression specifying the data to write.

The value returned by sprintf is greater than or equal to zero if the operation is successful or in other words the number of characters written, not counting the terminating null character is returned and returns a value less than zero if an error occurred.

printf: Prints to stdout

Syntax for printf is:

printf format [argument]…

The only difference between sprintf() and printf() is that sprintf() writes data into a character array, while printf() writes data to stdout, the standard output device.

Here is very sample solution for check class (hasClass) in Javascript:

const mydivclass = document.querySelector('.mydivclass');
// if 'hasClass' is exist on 'mydivclass'
if(mydivclass.classList.contains('hasClass')) {
   // do something if 'hasClass' is exist.
}

Just add overflow:hidden to the table with border-radius.

.tablewithradius {
  overflow:hidden ;
  border-radius: 15px;
}

Your arguments are incorrect, error doesn't return an object containing status and message, it passed them as separate parameters in the order described below.

Taken from the angular docs:

• data – {string|Object} – The response body transformed with the transform functions.
• status – {number} – HTTP status code of the response.
• headers – {function([headerName])} – Header getter function.
• config – {Object} – The configuration object that was used to generate the request.
• statusText – {string} – HTTP status text of the response.

So you'd need to change your code to:

$http.get(dataUrl)
    .success(function (data){
        $scope.data.products = data;
    })
    .error(function (error, status){
        $scope.data.error = { message: error, status: status};
        console.log($scope.data.error.status); 
  }); 

Obviously, you don't have to create an object representing the error, you could just create separate scope properties but the same principle applies.

Combining Daniel's and snnsnn's answers:

let ids = ['id1','id2','id3']
let data = await MyModel.find(
  {'_id': { $in: ids}}
);

Simple and clean code. It works and tested against:

"mongodb": "^3.6.0", "mongoose": "^5.10.0",

I had similar problem. Provided xml sample is put as single ListViewItem, and i couldn't click on Item itself, but checkbox was workng.

Solution: add attribute

to CheckBox control.

Example, Order of inheritance is assumed as O > S > T > U > V

Using extends Keyword ,

Correct:

List<? extends T> Object = new List<T>();
List<? extends T> Object = new List<U>();
List<? extends T> Object = new List<V>();

InCorrect:

List<? extends T> Object = new List<S>();
List<? extends T> Object = new List<O>();

super Keyword:

Correct:

List<? super T> Object = new List<T>();
List<? super T> Object = new List<S>();
List<? super T> Object = new List<O>();

InCorrect:

List<? super T> Object = new List<U>();
List<? super T> Object = new List<V>();

Adding object: List Object = new List();

Object.add(new T()); //error

But Why error ? Let's look at the Possibilities of initializations of List Object

List<? extends T> Object = new List<T>();
List<? extends T> Object = new List<U>();
List<? extends T> Object = new List<V>();

If we use Object.add(new T()); then it will be correct only if

List<? extends T> Object = new List<T>(); 

But there are extra two possibilities

List Object = new List(); List Object = new List(); If we try to add (new T()) to the above two possibilities it will give an error because T is the superior class of U and V . we try to add a T object [which is (new T()) ] to List of type U and V . Higher class object(Base class) cannot be passed to lower class Object(Sub class).

Due to the extra two possibilities , Java gives you error even if you use the correct possilibity as Java don't know what Object you are referring to .So you can't add objects to List Object = new List(); as there are possibilities that are not valid.

Adding object: List Object = new List();

Object.add(new T()); // compiles fine without error
Object.add(new U()); // compiles fine without error
Object.add(new V()); // compiles fine without error

Object.add(new S()); //  error
Object.add(new O()); //  error

But why error occurs in the above two ? we can use Object.add(new T()); only on the below possibilities,

List<? super T> Object = new List<T>();
List<? super T> Object = new List<S>();
List<? super T> Object = new List<O>();

If we Tried to use Object.add(new T()) in List Object = new List(); and List Object = new List(); then it will give error This is because We can't add T object[which is new T()] to the List Object = new List(); because it is an object of type U . We can't add a T object[which is new T()] to U Object because T is a base class and U is a sub class . We can't add base class to subclass and that's why error occurs . This is same for the another case .

I know the question is for JUnit4, but if you happen to be stuck at JUnit3, you could create a short utility function like that:

private void assertArrayEquals(Object[] esperado, Object[] real) {
    assertEquals(Arrays.asList(esperado), Arrays.asList(real));     
}

In JUnit3, this is better than directly comparing the arrays, since it will detail exactly which elements are different.

just an additional comment to the approved answer. You may get a crash when moving the cursor on edittext field due to parsing. I did a try catch statement, but implement your own code.

@Override public void onTextChanged(CharSequence s, int start, int before, int count) {
        if(!s.toString().equals(current)){
        amountEditText.removeTextChangedListener(this);

            String cleanString = s.toString().replaceAll("[$,.]", "");

            try{
                double parsed = Double.parseDouble(cleanString);
                String formatted = NumberFormat.getCurrencyInstance().format((parsed/100));
                current = formatted;
                amountEditText.setText(formatted);
                amountEditText.setSelection(formatted.length());
            } catch (Exception e) {

            }

            amountEditText.addTextChangedListener(this);
        }
    }

I had the same problem in Visual Studio Pro 2017: missing MSVCP120.dll file in Release mode and missing MSVCP120d.dll file in Debug mode. I installed Visual C++ Redistributable Packages for Visual Studio 2013 and Update for Visual C++ 2013 and Visual C++ Redistributable Package as suggested here Microsoft answer this fixed the release mode. For the debug mode what eventually worked was to copy msvcp120d.dll and msvcr120d.dll from a different computer (with Visual studio 2013) into C:\Windows\System32

dynamic version

    ALTER PROCEDURE [dbo].[ReseedTableIdentityCol](@p_table varchar(max))-- RETURNS int

    BEGIN
        -- Declare the return variable here
       DECLARE @sqlCommand nvarchar(1000)
       DECLARE @maxVal INT
       set @sqlCommand = 'SELECT @maxVal = ISNULL(max(ID),0)+1 from '+@p_table
       EXECUTE sp_executesql @sqlCommand, N'@maxVal int OUTPUT',@maxVal=@maxVal OUTPUT

Here is my solution, there is no way to use momemt.js.Here is DataTable with Two DatePickers for DateRange (To and From) Filter.

$.fn.dataTable.ext.search.push(
  function (settings, data, dataIndex) {
    var min = $('#min').datepicker("getDate");
    var max = $('#max').datepicker("getDate");
    var startDate = new Date(data[4]);
    if (min == null && max == null) { return true; }
    if (min == null && startDate <= max) { return true; }
    if (max == null && startDate >= min) { return true; }
    if (startDate <= max && startDate >= min) { return true; }
    return false;
  }
);
  

    

To modify a global variable inside a function, you must use the global keyword.

When you try to do this without the line

global counter

inside of the definition of increment, a local variable named counter is created so as to keep you from mucking up the counter variable that the whole program may depend on.

Note that you only need to use global when you are modifying the variable; you could read counter from within increment without the need for the global statement.

import subprocess
cmd = "vsish -e ls /vmkModules/lsom/disks/  | cut -d '/' -f 1  | while read diskID  ; do echo $diskID; vsish -e cat /vmkModules/lsom/disks/$diskID/virstoStats | grep -iE 'Delete pending |trims currently queued' ;  echo '====================' ;done ;"


def subprocess_cmd(command):
    process = subprocess.Popen(command,stdout=subprocess.PIPE, shell=True)
    proc_stdout = process.communicate()[0].strip()
    for line in proc_stdout.decode().split('\n'):
        print (line)

subprocess_cmd(cmd)

Try to check if you have .env file.

Mostly this thing can cause something like that. Try to create a file then copy everything from .env.example, paste it to your created file and name it .env. or jsut simply rename the .env.example file to .env and run php artisan key:generate

Here is an image from notepad++ when you select text to copy as html.

and how the formatted text looks like after pasting it in OneNote (similar to any other app that supports "Paste Special"):

Yet another way to use Rscript for *Unix systems is Process Substitution.

Rscript <(zcat a.r)
# [1] "hello"

Which obviously does the same as the accepted answer, but this allows you to manipulate and run your file without saving it the power of the command line, e.g.:

Rscript <(sed s/hello/bye/ a.r)
# [1] "bye"

Similar to Rscript -e "Rcode" it also allows to run without saving into a file. So it could be used in conjunction with scripts that generate R-code, e.g.:

Rscript <(echo "head(iris,2)")
# Sepal.Length Sepal.Width Petal.Length Petal.Width Species
# 1          5.1         3.5          1.4         0.2  setosa
# 2          4.9         3.0          1.4         0.2  setosa

As others have said, usually you want to use hg backout or git revert. However, sometimes you really want to get rid of a commit.

First, you'll want to go to your repository's settings. Click on the Strip commits link.

Enter the changeset ID for the changeset you want to destroy, and click Preview strip. That will let you see what kind of damage you're about to do before you do it. Then just click Confirm and your commit is no longer history. Make sure you tell all your collaborators what you've done, so they don't accidentally push the offending commit back.
