If you are using Spring as Back-End server and especially using Spring Security then i found a solution by putting http.cors(); in the configure method. The method looks like that:

protected void configure(HttpSecurity http) throws Exception {
        http
                .csrf().disable()
                .authorizeRequests() // authorize
                .anyRequest().authenticated() // all requests are authenticated
                .and()
                .httpBasic();

        http.cors();
}

The problem I run into is I have an existing IIS machine. I then deploy a static React app to it. When you use router, the URL that displays is actually virtual, not real. If you hit F5 it goes to IIS, not index.js, and your return will be 404 file not found. How I resolved it was simple. I have a public folder in my react app. In that public folder I created the same folder name as the virtual routing. In this folder, I have an index.html with the following code:

<script>
  {
    localStorage.setItem("redirect", "/ansible/");
    location.href = "/";
  }
</script>

Now what this does is for this session, I'm adding the "routing" path I want it to go. Then inside my App.js I do this (Note ... is other code but too much to put here for a demo):

import React, { Component } from "react";
import { Route, Link } from "react-router-dom";
import { BrowserRouter as Router } from "react-router-dom";
import { Redirect } from 'react-router';
import Ansible from "./Development/Ansible";
import Code from "./Development/Code";
import Wood from "./WoodWorking";
import "./App.css";

class App extends Component {
  render() {
    const redirect = localStorage.getItem("redirect");

    if(redirect) {
      localStorage.removeItem("redirect");
    }

    return (
      <Router>
        {redirect ?<Redirect to={redirect}/> : ""}
        <div className="App">
        ...
          <Link to="/">
            <li>Home</li>
          </Link>
          <Link to="/dev">
            <li>Development</li>
          </Link>
          <Link to="/wood">
            <li>Wood Working</li>
          </Link>
        ...
          <Route
            path="/"
            exact
            render={(props) => (
              <Home {...props} />
            )}
          />
          <Route
            path="/dev"
            render={(props) => (
              <Code {...props} />
            )}
          />
          <Route
            path="/wood"
            render={(props) => (
              <Wood {...props} />
            )}
          />
          <Route
            path="/ansible/"
            exact
            render={(props) => (
              <Ansible {...props} checked={this.state.checked} />
            )}
          />
          ...
      </Router>
    );
  }
}

export default App;

To name a few we can use redux-react-session which is having good API for session management like, initSessionService, refreshFromLocalStorage, checkAuth and many other. It also provide some advanced functionality like Immutable JS.

Alternatively we can leverage react-web-session which provides options like callback and timeout.

In .NET Core 2.0 the user already exists as part of the underlying inherited controller. Just use the User as you would normally or pass across to any repository code.

[Authorize(AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme, Policy = "TENANT")]
[HttpGet("issue-type-selection"), Produces("application/json")]
public async Task<IActionResult> IssueTypeSelection()
{
    try
    {
        return new ObjectResult(await _item.IssueTypeSelection(User));
    }
    catch (ExceptionNotFound)
    {
        Response.StatusCode = (int)HttpStatusCode.BadRequest;
        return Json(new
        {
            error = "invalid_grant",
            error_description = "Item Not Found"
        });
    }
}

$Group is an object, but you will actually need to check if $Group.samaccountname.StartsWith("string").

Change $Group.StartsWith("S_G_") to $Group.samaccountname.StartsWith("S_G_").

I had this issue after converting my Write-Host cmdlets to Write-Information and I was missing quotes and parens around the parameters. The cmdlet signatures are evidently not the same.

Write-Host this is a good idea $here
Write-Information this is a good idea $here <=BAD

This is the cmdlet signature that corrected after spending 20-30 minutes digging down the function stack...

Write-Information ("this is a good idea $here") <=GOOD

I'm running a Mickey Mouse testing system based on SQL.COM.

I ran setspn -T sql -F -Q */Servername (in this case SQL01) on both the machine I couldn't connect to and a machine I could. I then simply removed the additional entries in the problem machine and it all worked, e.g. setspn -D MSSQLSvc/SQL01.SQL.COM:1433 SQL01

The URL structure you're referring to is called the REST endpoint, as opposed to the Web Site Endpoint.

Note: Since this answer was originally written, S3 has rolled out dualstack support on REST endpoints, using new hostnames, while leaving the existing hostnames in place. This is now integrated into the information provided, below.

If your bucket is really in the us-east-1 region of AWS -- which the S3 documentation formerly referred to as the "US Standard" region, but was subsequently officially renamed to the "U.S. East (N. Virginia) Region" -- then http://s3-us-east-1.amazonaws.com/bucket/ is not the correct form for that endpoint, even though it looks like it should be. The correct format for that region is either http://s3.amazonaws.com/bucket/ or http://s3-external-1.amazonaws.com/bucket/.¹

The format you're using is applicable to all the other S3 regions, but not US Standard US East (N. Virginia) [us-east-1].

S3 now also has dual-stack endpoint hostnames for the REST endpoints, and unlike the original endpoint hostnames, the names of these have a consistent format across regions, for example s3.dualstack.us-east-1.amazonaws.com. These endpoints support both IPv4 and IPv6 connectivity and DNS resolution, but are otherwise functionally equivalent to the existing REST endpoints.

If your permissions and configuration are set up such that the web site endpoint works, then the REST endpoint should work, too.

However... the two endpoints do not offer the same functionality.

Roughly speaking, the REST endpoint is better-suited for machine access and the web site endpoint is better suited for human access, since the web site endpoint offers friendly error messages, index documents, and redirects, while the REST endpoint doesn't. On the other hand, the REST endpoint offers HTTPS and support for signed URLs, while the web site endpoint doesn't.

Choose the correct type of endpoint (REST or web site) for your application:

http://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteEndpoints.html#WebsiteRestEndpointDiff

¹ s3-external-1.amazonaws.com has been referred to as the "Northern Virginia endpoint," in contrast to the "Global endpoint" s3.amazonaws.com. It was unofficially possible to get read-after-write consistency on new objects in this region if the "s3-external-1" hostname was used, because this would send you to a subset of possible physical endpoints that could provide that functionality. This behavior is now officially supported on this endpoint, so this is probably the better choice in many applications. Previously, s3-external-2 had been referred to as the "Pacific Northwest endpoint" for US-Standard, though it is now a CNAME in DNS for s3-external-1 so s3-external-2 appears to have no purpose except backwards-compatibility.

The extension method worked great for me with one exception that if the user logs out there old claim sets still existed so with a tiny modification as in passing usermanager through everything works great and you dont need to logout and login. I cant answer directly as my reputation has been dissed :(

public static class ClaimExtensions
{
    public static void AddUpdateClaim(this IPrincipal currentPrincipal,    string key, string value, ApplicationUserManager userManager)
    {
        var identity = currentPrincipal.Identity as ClaimsIdentity;
        if (identity == null)
            return;

        // check for existing claim and remove it
        var existingClaim = identity.FindFirst(key);
        if (existingClaim != null)
        {
            RemoveClaim(currentPrincipal, key, userManager);
        }

        // add new claim
        var claim = new Claim(key, value);
        identity.AddClaim(claim);
        var authenticationManager = HttpContext.Current.GetOwinContext().Authentication;
        authenticationManager.AuthenticationResponseGrant = new AuthenticationResponseGrant(new ClaimsPrincipal(identity), new AuthenticationProperties() { IsPersistent = true });
        //Persist to store
        userManager.AddClaim(identity.GetUserId(),claim);

    }

            return ;

        // check for existing claim and remove it
        var existingClaims = identity.FindAll(key);
        existingClaims.ForEach(c=> identity.RemoveClaim(c));

        //remove old claims from store
        var user = userManager.FindById(identity.GetUserId());
        var claims =  userManager.GetClaims(user.Id);
        claims.Where(x => x.Type == key).ToList().ForEach(c => userManager.RemoveClaim(user.Id, c));

    }

Thanks to Stein. it is the Enter key not any key.

I encountered the write:errno=104 attempting to test connecting to an SSL-enabled RabbitMQ broker port with openssl s_client.

The issue turned out to be simply that the user RabbitMQ was running as did not have read permissions on the certificate file. There was little-to-no useful logging in RabbitMQ.

Request.GetOwinContext().Authentication.User.Claims

However it is better to add the claims inside the "GenerateUserIdentityAsync" method, especially if regenerateIdentity in the Startup.Auth.cs is enabled.

I was successfully available to get Application User By Following Piece of Code

var manager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
            var user = manager.FindById(User.Identity.GetUserId());
            ApplicationUser EmpUser = user;

SQL Logins are defined at the server level, and must be mapped to Users in specific databases.

In SSMS object explorer, under the server you want to modify, expand Security > Logins, then double-click the appropriate user which will bring up the "Login Properties" dialog.

Select User Mapping, which will show all databases on the server, with the ones having an existing mapping selected. From here you can select additional databases (and be sure to select which roles in each database that user should belong to), then click OK to add the mappings.

These mappings can become disconnected after a restore or similar operation. In this case, the user may still exist in the database but is not actually mapped to a login. If that happens, you can run the following to restore the login:

USE {database};
ALTER USER {user} WITH login = {login}

You can also delete the DB user and recreate it from the Login Properties dialog, but any role memberships or other settings would need to be recreated.

SELECT name FROM sys.database_principals WHERE
type_desc = 'SQL_USER' AND default_schema_name = 'dbo'

This selects all the users in the SQL server that the administrator created!

In my case it was related to a .ps1 referral inside the ps1 script which was not signed (you need to unblock it at the file properties) , also I added as first line:

Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Force

Then it worked

Assuming your controller's action method is something like this:

public ActionResult AllCategories(int id = 0)
{
    return View(db.Categories.Include(p => p.Products).ToList());
}

Modify your models to be something like this:

public class Product
{
    [Key]
    public int ID { get; set; }
    public int CategoryID { get; set; }
    //new code
    public virtual Category Category { get; set; }
    public string Title { get; set; }
    public string Description { get; set; }
    public string Path { get; set; }

    //remove code below
    //public virtual ICollection<Category> Categories { get; set; }
}

public class Category
{
    [Key]
    public int CategoryID { get; set; }
    public string Name { get; set; }
    //new code
    public virtual ICollection<Product> Products{ get; set; }
}

Then your since now the controller takes in a Category as Model (instead of a Product):

foreach (var category in Model)
{
    <h3><u>@category.Name</u></h3>
    <div>
        <ul>    
            @foreach (var product in Model.Products)
            {
                // cut for brevity, need to add back more code from original
                <li>@product.Title</li>
            }
        </ul>
    </div>
}

UPDATED: Add ToList() to the controller return statement.

As pointed already by @Arun P Johny the root cause of the problem is that at the moment when AuthenticationSuccessEvent is processed SecurityContextHolder is not populated by Authentication object. So any declarative authorization checks (that must get user rights from SecurityContextHolder) will not work. I give you another idea how to solve this problem. There are two ways how you can run your custom code immidiately after successful authentication:

1. Listen to AuthenticationSuccessEvent
2. Provide your custom AuthenticationSuccessHandler implementation.

AuthenticationSuccessHandler has one important advantage over first way: SecurityContextHolder will be already populated. So just move your stateService.rowCount() call into loginsuccesshandler.LoginSuccessHandler#onAuthenticationSuccess(...) method and the problem will go away.

Create a class TestUserDetailsImpl on your test package:

@Service
@Primary
@Profile("test")
public class TestUserDetailsImpl implements UserDetailsService {
    public static final String API_USER = "[email protected]";

    private User getAdminUser() {
        User user = new User();
        user.setUsername(API_USER);

        SimpleGrantedAuthority role = new SimpleGrantedAuthority("ROLE_API_USER");
        user.setAuthorities(Collections.singletonList(role));

        return user;
    }

    @Override
    public UserDetails loadUserByUsername(String username) 
                                         throws UsernameNotFoundException {
        if (Objects.equals(username, ADMIN_USERNAME))
            return getAdminUser();
        throw new UsernameNotFoundException(username);
    }
}

Rest endpoint:

@GetMapping("/invoice")
@Secured("ROLE_API_USER")
public Page<InvoiceDTO> getInvoices(){
   ...
}

Test endpoint:

@Test
@WithUserDetails("[email protected]")
public void testApi() throws Exception {
     ...
}

When you’re faced with a problem to solve (and frankly, who isn’t these days?), the basic strategy usually taken by we computer people is called “divide and conquer.” It goes like this:

• Conceptualize the specific problem as a set of smaller sub-problems.
• Solve each smaller problem.
• Combine the results into a solution of the specific problem.

But “divide and conquer” is not the only possible strategy. We can also take a more generalist approach:

• Conceptualize the specific problem as a special case of a more general problem.
• Somehow solve the general problem.
• Adapt the solution of the general problem to the specific problem.

- Eric Lippert

I believe many solutions already exist for this problem in server-side languages such as ASP.Net/C#.

I've outlined some of the major aspects of the problem

• Issue: We need to load data only for the desired language

  Solution: For this purpose we save data to a separate files for each language

ex. res.de.js, res.fr.js, res.en.js, res.js(for default language)

• Issue: Resource files for each page should be separated so we only get the data we need

  Solution: We can use some tools that already exist like https://github.com/rgrove/lazyload

• Issue: We need a key/value pair structure to save our data

  Solution: I suggest a javascript object instead of string/string air. We can benefit from the intellisense from an IDE

• Issue: General members should be stored in a public file and all pages should access them

  Solution: For this purpose I make a folder in the root of web application called Global_Resources and a folder to store global file for each sub folders we named it 'Local_Resources'

• Issue: Each subsystems/subfolders/modules member should override the Global_Resources members on their scope

  Solution: I considered a file for each

Application Structure

root/
    Global_Resources/
        default.js
        default.fr.js
    UserManagementSystem/
        Local_Resources/
            default.js
            default.fr.js
            createUser.js
        Login.htm
        CreateUser.htm

The corresponding code for the files:

Global_Resources/default.js

var res = {
    Create : "Create",
    Update : "Save Changes",
    Delete : "Delete"
};

Global_Resources/default.fr.js

var res = {
    Create : "créer",
    Update : "Enregistrer les modifications",
    Delete : "effacer"
};

The resource file for the desired language should be loaded on the page selected from Global_Resource - This should be the first file that is loaded on all the pages.

UserManagementSystem/Local_Resources/default.js

res.Name = "Name";
res.UserName = "UserName";
res.Password = "Password";

UserManagementSystem/Local_Resources/default.fr.js

res.Name = "nom";
res.UserName = "Nom d'utilisateur";
res.Password = "Mot de passe";

UserManagementSystem/Local_Resources/createUser.js

// Override res.Create on Global_Resources/default.js
res.Create = "Create User"; 

UserManagementSystem/Local_Resources/createUser.fr.js

// Override Global_Resources/default.fr.js
res.Create = "Créer un utilisateur";

manager.js file (this file should be load last)

res.lang = "fr";

var globalResourcePath = "Global_Resources";
var resourceFiles = [];

var currentFile = globalResourcePath + "\\default" + res.lang + ".js" ;

if(!IsFileExist(currentFile))
    currentFile = globalResourcePath + "\\default.js" ;
if(!IsFileExist(currentFile)) throw new Exception("File Not Found");

resourceFiles.push(currentFile);

// Push parent folder on folder into folder
foreach(var folder in parent folder of current page)
{
    currentFile = folder + "\\Local_Resource\\default." + res.lang + ".js";

    if(!IsExist(currentFile))
        currentFile = folder + "\\Local_Resource\\default.js";
    if(!IsExist(currentFile)) throw new Exception("File Not Found");

    resourceFiles.push(currentFile);
}

for(int i = 0; i < resourceFiles.length; i++) { Load.js(resourceFiles[i]); }

// Get current page name
var pageNameWithoutExtension = "SomePage";

currentFile = currentPageFolderPath + pageNameWithoutExtension + res.lang + ".js" ;

if(!IsExist(currentFile))
    currentFile = currentPageFolderPath + pageNameWithoutExtension + ".js" ;
if(!IsExist(currentFile)) throw new Exception("File Not Found");

Hope it helps :)

Do Graphically.

Database right click-->properties-->files-->select database owner-->select [sa]-- ok

Scenario:

I am working on a multi-module Gradle project.

Modules are:

- core, 
- service,
- geo,
- report,
- util and
- some other modules.

So primarily we have prepared a Component[locationRecommendHttpClientBuilder] in geo module.

Java Code:

import org.springframework.stereotype.Component

@Component("locationRecommendHttpClientBuilder")
class LocationRecommendHttpClientBuilder extends PanaromaHttpClientBuilder {
    @Override
    PanaromaHttpClient buildFromConfiguration() {
        this.setURL(PanaromaConf.getInstance().getString("locationrecommend.url"))
        this.setMethod(PanaromaConf.getInstance().getString("locationrecommend.method"))
        this.setProxyHost(PanaromaConf.getInstance().getString("locationrecommend.proxy.host"))
        this.setProxyPort(PanaromaConf.getInstance().getInt("locationrecommend.proxy.port", 0))
        return super.build()
    }
}

application-context.xml

<bean id="locationRecommendHttpClient"
      class="au.co.google.panaroma.platform.logic.impl.PanaromaHttpClient"
      scope="singleton" factory-bean="locationRecommendHttpClientBuilder"
      factory-method="buildFromConfiguration" />

Then it is decided to add this component in core module.

One engineer has previous code for geo module and then he has taken the latest module of core but he forgot to take the latest geo module.

So the component[locationRecommendHttpClientBuilder] is double times in his project and he was getting the following error.

Caused by: org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'LocationRecommendHttpClientBuilder' for bean class [au.co.google.app.locationrecommendation.builder.LocationRecommendHttpClientBuilder] conflicts with existing, non-compatible bean definition of same name and class [au.co.google.panaroma.platform.logic.impl.locationRecommendHttpClientBuilder]

Solution Procedure:

After removal the component from geo module, component[locationRecommendHttpClientBuilder] is only available in core module. So there is no conflicting situation. Issue is solved by this way.

This is a job for numpy.

FWIW, in our case a (PHP) website running on IIS was showing this message on attempting to connect to a database.

The resolution was to edit the Anonymous Authentication on that website to use the Application pool identity (and we set the application pool entry up to use a service account designed for that website).

This is my LDAP Java login test application supporting LDAP:// and LDAPS:// self-signed test certificate. Code is taken from few SO posts, simplified implementation and removed legacy sun.java.* imports.

• how to accept self-signed certificates for JNDI/LDAP connections?
• Authenticating against Active Directory with Java on Linux

Usage
I have run this in Windows7 and Linux machines against WinAD directory service. Application prints username and member groups.

$ java -cp classes test.LoginLDAP url=ldap://1.2.3.4:389 [email protected] password=mypwd

$ java -cp classes test.LoginLDAP url=ldaps://1.2.3.4:636 [email protected] password=mypwd

Test application supports temporary self-signed test certificates for ldaps:// protocol, this DummySSLFactory accepts any server cert so man-in-the-middle is possible. Real life installation should import server certificate to a local JKS keystore file and not using dummy factory.

Application uses enduser's username+password for initial context and ldap queries, it works for WinAD but don't know if can be used for all ldap server implementations. You could create context with internal username+pwd then run queries to see if given enduser is found.

Starting with Spring Security version 3.2, the custom functionality that has been implemented by some of the older answers, exists out of the box in the form of the @AuthenticationPrincipal annotation that is backed by AuthenticationPrincipalArgumentResolver.

An simple example of it's use is:

@Controller
public class MyController {
   @RequestMapping("/user/current/show")
   public String show(@AuthenticationPrincipal CustomUser customUser) {
        // do something with CustomUser
       return "view";
   }
}

CustomUser needs to be assignable from authentication.getPrincipal()

Here are the corresponding Javadocs of AuthenticationPrincipal and AuthenticationPrincipalArgumentResolver

This works on firefox 3.6.x and IE:

    function copyToClipboardCrossbrowser(s) {           
        s = document.getElementById(s).value;               

        if( window.clipboardData && clipboardData.setData )
        {
            clipboardData.setData("Text", s);
        }           
        else
        {
            // You have to sign the code to enable this or allow the action in about:config by changing
            //user_pref("signed.applets.codebase_principal_support", true);
            netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect');

            var clip = Components.classes["@mozilla.org/widget/clipboard;1"].createInstance(Components.interfaces.nsIClipboard);
            if (!clip) return;

            // create a transferable

            var trans = Components.classes["@mozilla.org/widget/transferable;1"].createInstance(Components.interfaces.nsITransferable);
            if (!trans) return;

            // specify the data we wish to handle. Plaintext in this case.
            trans.addDataFlavor('text/unicode');

            // To get the data from the transferable we need two new objects
            var str = new Object();
            var len = new Object();

            var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);

            str.data= s;        

            trans.setTransferData("text/unicode",str, str.data.length * 2);

            var clipid=Components.interfaces.nsIClipboard;              
            if (!clip) return false;
            clip.setData(trans,null,clipid.kGlobalClipboard);

I just found this excellent little tutorial. broken link (Cached version)

I also followed Microsoft's tutorial which is nice, but I only needed pipes as well.

As you can see, you don't need configuration files and all that messy stuff.

By the way, he uses both HTTP and pipes. Just remove all code lines related to HTTP, and you'll get a pure pipe example.

I know this might sound silly, but I recently came across this myself, Make sure the domain controller is not read-only.

This is with reference to @Ladislav Mrnka's answer on using fluent api for configuring one-to-one relationship.

Had a situation where having FK of dependent must be it's PK was not feasible.

E.g., Foo already has one-to-many relationship with Bar.

public class Foo {
   public Guid FooId;
   public virtual ICollection<> Bars; 
}
public class Bar {
   //PK
   public Guid BarId;
   //FK to Foo
   public Guid FooId;
   public virtual Foo Foo;
}

Now, we had to add another one-to-one relationship between Foo and Bar.

public class Foo {
   public Guid FooId;
   public Guid PrimaryBarId;// needs to be removed(from entity),as we specify it in fluent api
   public virtual Bar PrimaryBar;
   public virtual ICollection<> Bars;
}
public class Bar {
   public Guid BarId;
   public Guid FooId;
   public virtual Foo PrimaryBarOfFoo;
   public virtual Foo Foo;
}

Here is how to specify one-to-one relationship using fluent api:

modelBuilder.Entity<Bar>()
            .HasOptional(p => p.PrimaryBarOfFoo)
            .WithOptionalPrincipal(o => o.PrimaryBar)
            .Map(x => x.MapKey("PrimaryBarId"));

Note that while adding PrimaryBarId needs to be removed, as we specifying it through fluent api.

Also note that method name [WithOptionalPrincipal()][1] is kind of ironic. In this case, Principal is Bar. WithOptionalDependent() description on msdn makes it more clear.

sp_change_users_login is deprecated.

Much easier is:

ALTER USER usr1 WITH LOGIN = login1;

Using System.Web.HttpContext.Current.User.Identity.Name should work. Please check the IIS Site settings on the server that is hosting your site by doing the following:

1. Go to IIS ? Sites ? Your Site ? Authentication

   

2. Now check that Anonymous Access is Disabled & Windows Authentication is Enabled.

   

3. Now System.Web.HttpContext.Current.User.Identity.Name should return something like this:

   domain\username

In my case the solution was (on top of adjustments suggested above) to restart my/users' local development computer / IIS (hosting server). My user has just been added to the newly created AD security group - and policy didn't apply to user AD account until I logged out/restarted my computer.

Hope this will help someone.

My solution:

UserPrincipal user = UserPrincipal.FindByIdentity(new PrincipalContext(ContextType.Domain, myDomain), IdentityType.SamAccountName, myUser);
List<string> UserADGroups = new List<string>();            
foreach (GroupPrincipal group in user.GetGroups())
{
    UserADGroups.Add(group.ToString());
}

I solved this problem by setting UseCookies in web.config.

  <system.web>
    <sessionState cookieless="UseCookies" />

and setting enableVersionHeader

  <system.web>
    <httpRuntime targetFramework="4.5.1" enableVersionHeader="false" executionTimeout="1200" shutdownTimeout="1200" maxRequestLength="103424" />

If you want to filter y active accounts add this to Harvey's code:

 UserPrincipal userPrin = new UserPrincipal(context);
 userPrin.Enabled = true;

after the first using. Then add

  searcher.QueryFilter = userPrin;

before the find all. And that should get you the active ones.

This is a simple example of what I used for a recent test. You need to make sure that your security settings are the same on the server and client.

var myBinding = new BasicHttpBinding();
myBinding.Security.Mode = BasicHttpSecurityMode.None;
var myEndpointAddress = new EndpointAddress("http://servername:8732/TestService/");
client = new ClientTest(myBinding, myEndpointAddress);
client.someCall();

Just want to add my two cents on this old post:

In my opinion, almost all of relational database engines include a commit transaction execution automatically after execute a DDL command even when you have autocommit=false, So you don't need to start a transaction to avoid a potential truncated object creation because It is completely unnecessary.

To fix this, open the SQL Server Management Studio and click New Query. Then type:

USE mydatabase
exec sp_changedbowner 'sa', 'true'

Link to a stored-procedure-less approach that Bart Gawrych posted on Dataedo site

I was asking myself, 'Do we really have to use a stored procedure here?' and I found this helpful post. (The state=0 was added to fix issues with offline databases per feedback from users of the linked page.)

declare @sql nvarchar(max);

select @sql = 
    (select ' UNION ALL
        SELECT ' +  + quotename(name,'''') + ' as database_name,
               s.name COLLATE DATABASE_DEFAULT
                    AS schema_name,
               t.name COLLATE DATABASE_DEFAULT as table_name 
               FROM '+ quotename(name) + '.sys.tables t
               JOIN '+ quotename(name) + '.sys.schemas s
                    on s.schema_id = t.schema_id'
    from sys.databases 
    where state=0
    order by [name] for xml path(''), type).value('.', 'nvarchar(max)');

set @sql = stuff(@sql, 1, 12, '') + ' order by database_name, 
                                               schema_name,
                                               table_name';

execute (@sql);

Here is a solution if you need to hook up some methods to @User for use in your views. No solution for any serious membership customization, but if the original question was needed for views alone then this perhaps would be enough. The below was used for checking a variable returned from a authorizefilter, used to verify if some links wehere to be presented or not(not for any kind of authorization logic or access granting).

using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using System.Security.Principal;

    namespace SomeSite.Web.Helpers
    {
        public static class UserHelpers
        {
            public static bool IsEditor(this IPrincipal user)
            {
                return null; //Do some stuff
            }
        }
    }

Then just add a reference in the areas web.config, and call it like below in the view.

@User.IsEditor()

Perhaps you get a blank page when you run from Visual Studio under development server using Windows authentication (previous topic).

If you deploy to IIS you can configure custom error pages for specific status codes, in this case 401. Add httpErrors under system.webServer:

<httpErrors>
  <remove statusCode="401" />
  <error statusCode="401" path="/yourapp/error/unauthorized" responseMode="Redirect" />
</httpErrors>

Then create ErrorController.Unauthorized method and corresponding custom view.

System.getProperty("user.name")

The "pre Windows 2000" name i.e. DOMAIN\SomeBody, the Somebody portion is known as sAMAccountName.

So try:

using(DirectoryEntry de = new DirectoryEntry("LDAP://MyDomainController"))
{
   using(DirectorySearcher adSearch = new DirectorySearcher(de))
   {
     adSearch.Filter = "(sAMAccountName=someuser)";
     SearchResult adSearchResult = adSearch.FindOne();
   }
}

[email protected] is the UserPrincipalName, but it isn't a required field.

Using a static in this case is the best way to write secure code.

Yes, statics are generally bad - generally, but in this case, the static is what you want. Since the security context associates a Principal with the currently running thread, the most secure code would access the static from the thread as directly as possible. Hiding the access behind a wrapper class that is injected provides an attacker with more points to attack. They wouldn't need access to the code (which they would have a hard time changing if the jar was signed), they just need a way to override the configuration, which can be done at runtime or slipping some XML onto the classpath. Even using annotation injection would be overridable with external XML. Such XML could inject the running system with a rogue principal.

runAllManagedModulesForAllRequests=true is actually a real bad solution. This increased the load time of my application by 200%. The better solution is to manually remove and add the session object and to avoid the run all managed modules attribute all together.

Or how can I reset without knowing the current one (user forgot password)?

If you want to change a password using the UserManager but you do not want to supply the user's current password, you can generate a password reset token and then use it immediately instead.

string resetToken = await UserManager.GeneratePasswordResetTokenAsync(model.Id);
IdentityResult passwordChangeResult = await UserManager.ResetPasswordAsync(model.Id, resetToken, model.NewPassword);

I ended up using

cookie_value = encodeURIComponent(my_string);

and

my_string = decodeURIComponent(cookie_value);

That seems to work for all kinds of characters. I had weird issues otherwise, even with characters that weren't semicolons or commas.

2007 is more powerful with ribbon..:=) To add new series in chart do: Select Chart, then click Design in Chart Tools on the ribbon, On the Design ribbon, select "Select Data" in Data Group, Then you will see the button for Add to add new series.

Hope that will help.

this works for me:

cmake -D DBUILD_SHARED_LIBS=ON DBUILD_STATIC_LIBS=ON DBUILD_TESTS=ON ..

In Linux, Open the VIM configuration file

$ sudo -H gedit /etc/vim/vimrc

Added following lines:

set fileencodings=utf-8,ucs-bom,gb18030,gbk,gb2312,cp936
set termencoding=utf-8
set encoding=utf-8

Save and exit, and terminal command:

$ source /etc/vim/vimrc

At this time VIM will correctly display Chinese.

You may want to consider a library to handle the deep link to your app:

https://github.com/airbnb/DeepLinkDispatch

You can add the intent filter on an annotated Activity like people suggested above. It will handle the routing and parsing of parameters for all of your deep links. For example, your MainActivity might have something like this:

@DeepLink("somePath/{useful_info_for_anton_app}")
public class MainActivity extends Activity {
   ...
}

It can also handle query parameters as well.

In my case, the route signature was different from the method parameter. I had id, but I was accepting documentId as parameter, that caused the problem.

[Route("Documents/{id}")]   <--- caused the webapi error
[Route("Documents/{documentId}")] <-- solved
public Document Get(string documentId)
{
  ..
}

You can get raw data using below method. BTW, this pattern is for Java 6. If you are using Java 7 or newer, please consider try-with-resources pattern.

And then you can use returned string with Google Gson to map JSON to object of specified class, like this:

String data = getJSON("http://localhost/authmanager.php");
AuthMsg msg = new Gson().fromJson(data, AuthMsg.class);
System.out.println(msg);

There is a sample of AuthMsg class:

public class AuthMsg {
    private int code;
    private String message;

    public int getCode() {
        return code;
    }
    public void setCode(int code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }
    public void setMessage(String message) {
        this.message = message;
    }
}

JSON returned by http://localhost/authmanager.php must look like this:

{"code":1,"message":"Logged in"}

In order to perform chmod, you need to be owner of the file you are trying to modify, or the root user.

An answer using PIL (just in case it's useful).

given a numpy array "A":

from PIL import Image
im = Image.fromarray(A)
im.save("your_file.jpeg")

you can replace "jpeg" with almost any format you want. More details about the formats here

Functions are indeed almost always the answer as already amply contributed and confirmed by this quote from the man page: "For almost every purpose, aliases are superseded by shell functions."

For completeness and because this can be useful (marginally more lightweight syntax) it could be noted that when the parameter(s) follow the alias, they can still be used (although this wouldn't address the OP's requirement). This is probably easiest to demonstrate with an example:

alias ssh_disc='ssh -O stop'

allows me to type smth like ssh_disc myhost, which gets expanded as expected as: ssh -O stop myhost

This can be useful for commands which take complex arguments (my memory isn't what it use t be anymore...)

Ok, if you are using Windows OS

1. Go to C:\Program Files\Java\jdk1.8.0_40\lib (jdk Version might be different for you)

2. Make sure tools.jar is present (otherwise download it)

3. Copy this path "C:\Program Files\Java\jdk1.8.0_40"

4. In pom.xml

   <dependency>
   <groupId>jdk.tools</groupId>
   <artifactId>jdk.tools</artifactId>
   <version>1.8.0_40</version>
   <scope>system</scope>
   <systemPath>C:/Program Files/Java/jdk1.8.0_40/lib/tools.jar</systemPath>
   </dependency>
   

5. Rebuild and run! BINGO!

I just had to face the same kind of issue with my Laravel 7 project, in Debian 10 shared hosting. I have to add RewriteBase / to my .htaccess within /public/ directory. So the .htaccess looks a like

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ /index.php [L,QSA]

mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, boolean given

This means that the first parameter you passed is a boolean (true or false).

The first parameter is $result, and it is false because there is a syntax error in the query.

" ... WHERE PartNumber = $partid';"

You should never directly include a request variable in a SQL query, else the users are able to inject SQL in your queries. (See SQL injection.)

You should escape the variable:

" ... WHERE PartNumber = '" . mysqli_escape_string($conn,$partid) . "';"

Or better, use Prepared Statements.

you can use this too

echo substr($_SERVER['HTTP_HOST'], 0, strrpos($_SERVER['HTTP_HOST'], '.', -5));

Use jQuery's $.param function to serialize the JSON data in requestData.

In short, using similar code as yours:

$http.post("/foo/bar",
$.param(requestData),
{
    headers:
    {
        'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
    }
}
).success(
    function(responseData) {
        //do stuff with response
    }
});

For using this, you have to include jQuery in your page along with AngularJS.

For me this code: df.loc[(df!=0).any(axis=0)] did not work. It returned the exact dataset.

Instead, I used df.loc[:, (df!=0).any(axis=0)] and dropped all the columns with 0 values in the dataset

The function .all() droped all the columns in which are any zero values in my dataset.

If you have WordPress bootstrap loaded you can use get_home_path() function to get path to the WordPress root directory.

Here is the Swift 5 version:

let delegate = UIApplication.shared.delegate as? AppDelegate

And to access the managed object context:

    if let delegate = UIApplication.shared.delegate as? AppDelegate {

        let moc = delegate.managedObjectContext
        
        // your code here
        
    }

or, using guard:

    guard let delegate = UIApplication.shared.delegate as? AppDelegate  else {
        return
    }

    let moc = delegate.managedObjectContext
        
    // your code here
    

Perfectly fine.
You can't instantiate abstract classes.. but abstract classes can be used to house common implementations for m1() and m3().
So if m2() implementation is different for each implementation but m1 and m3 are not. You could create different concrete IAnything implementations with just the different m2 implementation and derive from AbstractThing -- honoring the DRY principle. Validating if the interface is completely implemented for an abstract class is futile..

Update: Interestingly, I find that C# enforces this as a compile error. You are forced to copy the method signatures and prefix them with 'abstract public' in the abstract base class in this scenario.. (something new everyday:)

I hit this error ("stat /bin/bash: no such file or directory") when running the command:

docker exec -it 80372bc2c41e /bin/bash

The solution was to identify the kind of terminal (or shell) that is available on the container. To do so, I ran:

docker inspect 80372bc2c41e

In the output from that command, I saw:

"Cmd": [
    "/bin/sh",
    "-c",
    "gunicorn -b 0.0.0.0:7082 server.app:app"
],

This tells me that there's a /bin/sh command available, and I was able to connect with:

docker exec -it 80372bc2c41e /bin/sh

    this.toolStrip1 = new System.Windows.Forms.ToolStrip();
    this.toolStrip1.Location = new System.Drawing.Point(0, 0);

    this.toolStrip1.TabIndex = 0;
    this.toolStrip1.Text = "toolStrip1";
    object O = global::WindowsFormsApplication1.Properties.Resources.ResourceManager.GetObject("best_robust_ghost");

    ToolStripButton btn = new ToolStripButton("m1");
    btn.DisplayStyle = ToolStripItemDisplayStyle.Image;
    btn.Image = (Image)O;
    this.toolStrip1.Items.Add(btn);

    this.Controls.Add(this.toolStrip1);

When creating subdirectories hanging off from a non-existing parent directory(s) you must pass the -p flag to mkdir ... Please update your Dockerfile with

RUN mkdir -p ... 

I tested this and it's correct.

PriceList[0][1][2][3][4][5][6]

This says: go to the 1st item of my collection PriceList. That thing is a collection; get its 2nd item. That thing is a collection; get its 3rd...

Instead, you want slicing:

PriceList[:7] = [PizzaChange]*7

The issue turned out to be certificate-related. The WCF service called by the console app uses an X509 cert for authentication, which is installed on the servers that this script is hosted and run from.

On other servers, where the same services are consumed, the certificates were configured as follows:

winhttpcertcfg.exe -g -c LOCAL_MACHINE\My -s "certificate-name" -a "NETWORK SERVICE"

As they ran within the context of IIS. However, when the script was being run as it would in production, it's under the context of the user themselves. So, the script needed to be modified to the following:

winhttpcertcfg.exe -g -c LOCAL_MACHINE\My -s "certificate-name" -a "USERS"

Once that change was made, all was well. Thanks to everyone who offered assistance.

You want the :checkbox:checked selector and map to create an array of the values:

var checkedValues = $('input:checkbox:checked').map(function() {
    return this.value;
}).get();

If your checkboxes have a shared class it would be faster to use that instead, eg. $('.mycheckboxes:checked'), or for a common name $('input[name="Foo"]:checked')

- Update -

If you don't need IE support then you can now make the map() call more succinct by using an arrow function:

var checkedValues = $('input:checkbox:checked').map((i, el) => el.value).get();

I'd like to make some changes: In C, you can use the built in qsort command:

int compare( const void* a, const void* b)
{
   int int_a = * ( (int*) a );
   int int_b = * ( (int*) b );

   // an easy expression for comparing
   return (int_a > int_b) - (int_a < int_b);
}

qsort( a, 6, sizeof(int), compare )

First you have to remove the primary key of the table

ALTER TABLE nametable DROP PRIMARY KEY

and now yo can add the autoincrement ...

ALTER TABLE nametable ADD id INT NOT NULL AUTO_INCREMENT PRIMARY KEY

I think you can do something like this, the syntax might be wrong, havent used C# in a while To get the last item

Dictionary<string, int>.KeyCollection keys = mydict.keys;
string lastKey = keys.Last();

or use Max instead of Last to get the max value, I dont know which one fits your code better.

The url with /1.1/ in it is correct, it is the new Twitter API Version 1.1.

But you need an application and authorize your application (and the user) using oAuth.

Yes, running a 64-bit OS in VMWare is possible from a 32-bit OS if you have a 64 bit processor.

I have an old Intel Core 2 Duo with Windows XP Professional 2002 running on it, and I got it to work.

First of all, see if your CPU is capable of running a 64-bit OS. Search for 'Processor check for 64-bit compatibility' on the VMware site. Run the program.

If it says your processor is capable, restart your computer and go into the BIOS and see if you have 'Virtualization' and are able to enable it. I was able to and got Windows Server 2008 R2 running under VMware on this old laptop.

I hope it works for you!

You have to put it in the root directory, that corresponds to your execution context.

Example:

    MyProject
       src
           MyClass.java
           log4j.properties

If you start executing from a different project, you need to have that file in the project used for starting the execution. For example, if a different project holds some JUnit tests, it needs to have also its log4j.properties file.

I suggest using log4j.xml instead of the log4j.properties. You have more options, get assistance from your IDE and so on...

Firebase Remote Config is better.

• Quickly and easily update our applications without the need to publish a new build to the app

Implementing Remote Config on Android

Adding the Remote Config dependancy

compile 'com.google.firebase:firebase-config:9.6.0'

Once done, we can then access the FirebaseRemoteConfig instance throughout our application where required:

FirebaseRemoteConfig firebaseRemoteConfig = FirebaseRemoteConfig.getInstance();

Retrieving Remote Config values

boolean someBoolean = firebaseRemoteConfig.getBoolean("some_boolean");
byte[] someArray = firebaseRemoteConfig.getByteArray("some_array");
double someDouble = firebaseRemoteConfig.getDouble("some_double");
long someLong = firebaseRemoteConfig.getLong("some_long");
String appVersion = firebaseRemoteConfig.getString("appVersion");

Fetch Server-Side values

firebaseRemoteConfig.fetch(cacheExpiration)
            .addOnCompleteListener(new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {
                    if (task.isSuccessful()) {
                        mFirebaseRemoteConfig.activateFetched();
                        // We got our config, let's do something with it!
                        if(appVersion < CurrentVersion){
                           //show update dialog
                        }
                    } else {
                        // Looks like there was a problem getting the config...
                    }
                }
            });

Now once uploaded the new version to playstore, we have to update the version number inside firebase. Now if it is new version the update dialog will display

Super simple code using TryParse:

var value = "Active";

StatusEnum status;
if (!Enum.TryParse<StatusEnum>(value, out status))
    status = StatusEnum.Unknown;

Following these steps solved my problem.

1. Delete node_modules directory
2. Delete package-lock.json file
3. Start command prompt as Administrator <- important
4. Run npm install
5. Run npm run dev

As Luca indicated, add extra [] to your string and use the code below:

var myObject = eval('(' + myJSONtext + ')');

to test it you can use the snippet below.

var s =" [{'id':1,'name':'Test1'},{'id':2,'name':'Test2'}]";
var myObject = eval('(' + s + ')');
for (i in myObject)
{
   alert(myObject[i]["name"]);
}

hope it helps..

It is possible to roll your own version of PHP's die:

function test(arg1)
{
    arg1 = arg1 || die("arg1 is missing"); 
}

test();

If you don't use a passphrase, then the private key is not encrypted with any symmetric cipher - it is output completely unprotected.

You can generate a keypair, supplying the password on the command-line using an invocation like (in this case, the password is foobar):

openssl genrsa -aes128 -passout pass:foobar 3072

However, note that this passphrase could be grabbed by any other process running on the machine at the time, since command-line arguments are generally visible to all processes.

A better alternative is to write the passphrase into a temporary file that is protected with file permissions, and specify that:

openssl genrsa -aes128 -passout file:passphrase.txt 3072

Or supply the passphrase on standard input:

openssl genrsa -aes128 -passout stdin 3072

You can also used a named pipe with the file: option, or a file descriptor.

To then obtain the matching public key, you need to use openssl rsa, supplying the same passphrase with the -passin parameter as was used to encrypt the private key:

openssl rsa -passin file:passphrase.txt -pubout

(This expects the encrypted private key on standard input - you can instead read it from a file using -in <file>).

Example of creating a 3072-bit private and public key pair in files, with the private key pair encrypted with password foobar:

openssl genrsa -aes128 -passout pass:foobar -out privkey.pem 3072
openssl rsa -in privkey.pem -passin pass:foobar -pubout -out privkey.pub

From System Preferences, turn on the "Show Keyboard & Character Viewer in menu bar" setting.

Then, the "Character Viewer" menu will pop up a tool that will let you search for any unicode character (by name) and insert it ? you're all set.

"Stdafx.h" is a precompiled header.It include file for standard system include files and for project-specific include files that are used frequently but are changed infrequently.which reduces compile time and Unnecessary Processing.

Answer contribution by @anton-vbr

actually you shouldn't specify port in the host name. Mysql has special option for port (if port differs from default)

kind of

mysql --host=192.168.1.2 --port=3306

Try to call object like this:

(<any>Object).dosomething

This error has come because you have declared them as optional using ?. Now Typescript does strict check and it won't allow doing anything that may be undefined. Therefore, you can use (<any>yourObject) here.

Yes. You can throw anything you want: integers, strings, objects, whatever. If you want to throw an object, then simply create a new object, just as you would create one under other circumstances, and then throw it. Mozilla's Javascript reference has several examples.

I had the problem whereby VB6 IDE would not load the common controls (Sp6)with VB6 install on W7 64bit, specifically comctrl and msmask. I tried all the solutions proposed using regsrv32 (elevated), edited the registry, changing the version number in the vbp etc as proposed by MS and others. All failed. These solutions worked on my other 2 PCS but not this one. Eventually I removed IE11 and all worked properly afterwards. IE10 had never bene installed on thsi PC - we went straight from IE8 to IE11 and have been forced to backtrack to using IE8.

I have to say the simple solution above does not address the problem which is that the VB6 IDE will not load the common controls (using the Components menu selection under Project) - you get an error saying Object not loaded. So this will happen (and I proved this to myself) on any project, new or old that try to use theose common controls that will not load.

So my suggestion to anyone who has this problem is to try the manual register solution using regsrv32 route, then the edit the vbp to change the version, and if these fail uninstall IE11 (and defintely IE10). But this may still not be a 100% solution because if your existing project files ".vbp" contain references to the wrong common controls you need to correct that manually - this is where loading a new project, loading the Components you need inside the IDE, then edit the newly create vbp using notepad and copy the version numbers for the common controls to your existing vbp files.

Angular JS Code

    var app = angular.module("myApp", []);
 app.directive("fileInput", function($parse){
      return{
           link: function($scope, element, attrs){
                element.on("change", function(event){

                });
           }
      }
 });
 app.controller("myCtrl", function($scope, $http){
      $scope.IsVisible = false;
      $scope.uploadFile = function(){
           var form_data = new FormData();
           angular.forEach($scope.files, function(file){
                form_data.append('file', file); //form file
                                form_data.append('file_Name',$scope.fileName); //form text data
           });
           $http.post('upload.php', form_data,
           {
                //'file_Name':$scope.file_name;
                transformRequest: angular.identity,
                headers: {'Content-Type': undefined,'Process-Data': false}
           }).success(function(response){
             $scope.IsVisible = $scope.IsVisible = true;
                      $scope.response_msg=response;
               // alert(response);
               // $scope.select();
           });
      }

 });

This code should work reasonably well:

public static File createTempDir() {
    final String baseTempPath = System.getProperty("java.io.tmpdir");

    Random rand = new Random();
    int randomInt = 1 + rand.nextInt();

    File tempDir = new File(baseTempPath + File.separator + "tempDir" + randomInt);
    if (tempDir.exists() == false) {
        tempDir.mkdir();
    }

    tempDir.deleteOnExit();

    return tempDir;
}

if you have USB internet like me the emulator seems to dislike connection being turned on and off so you may need to restart the emulator

At first, a config file is appropriate for this kind of things but you may also use another approach, which is as given below (Laravel - 4):

// You can keep this in your filters.php file
App::before(function($request) {
    App::singleton('site_settings', function(){
        return Setting::all();
    });

    // If you use this line of code then it'll be available in any view
    // as $site_settings but you may also use app('site_settings') as well
    View::share('site_settings', app('site_settings'));
});

To get the same data in any controller you may use:

$site_settings = app('site_settings');

There are many ways, just use one or another, which one you prefer but I'm using the Container.

The standard exceptions can be constructed from a std::string:

#include <stdexcept>

char const * configfile = "hardcode.cfg";
std::string const anotherfile = get_file();

throw std::runtime_error(std::string("Failed: ") + configfile);
throw std::runtime_error("Error: " + anotherfile);

Note that the base class std::exception can not be constructed thus; you have to use one of the concrete, derived classes.

There's absolutely nothing wrong with including the entirety of jQuery within your Greasemonkey script. Just take the source, and place it at the top of your user script. No need to make a script tag, since you're already executing JavaScript!

The user only downloads the script once anyways, so size of script is not a big concern. In addition, if you ever want your Greasemonkey script to work in non-GM environments (such as Opera's GM-esque user scripts, or Greasekit on Safari), it'll help not to use GM-unique constructs such as @require.

One option to override CSS class in JavaScript is using an ID for the style element so that we can update the CSS class

function writeStyles(styleName, cssText) {
    var styleElement = document.getElementById(styleName);
    if (styleElement) document.getElementsByTagName('head')[0].removeChild(
        styleElement);
    styleElement = document.createElement('style');
    styleElement.type = 'text/css';
    styleElement.id = styleName;
    styleElement.innerHTML = cssText;
    document.getElementsByTagName('head')[0].appendChild(styleElement);
}

..

   var cssText = '.testDIV{ height:' + height + 'px !important; }';
    writeStyles('styles_js', cssText)

First:

• Choose an encoding. UTF-8 is generally a good choice; stick to an encoding which will definitely be valid on both sides. It would be rare to use something other than UTF-8 or UTF-16.

Transmitting end:

• Encode the string to bytes (e.g. text.getBytes(encodingName))
• Encode the bytes to base64 using the Base64 class
• Transmit the base64

Receiving end:

• Receive the base64
• Decode the base64 to bytes using the Base64 class
• Decode the bytes to a string (e.g. new String(bytes, encodingName))

So something like:

// Sending side
byte[] data = text.getBytes("UTF-8");
String base64 = Base64.encodeToString(data, Base64.DEFAULT);

// Receiving side
byte[] data = Base64.decode(base64, Base64.DEFAULT);
String text = new String(data, "UTF-8");

Or with StandardCharsets:

// Sending side
byte[] data = text.getBytes(StandardCharsets.UTF_8);
String base64 = Base64.encodeToString(data, Base64.DEFAULT);

// Receiving side
byte[] data = Base64.decode(base64, Base64.DEFAULT);
String text = new String(data, StandardCharsets.UTF_8);

I question the logic of raising a PropertyChanged event on the second property when it's the first property that's changing. If the second properties value changes then the PropertyChanged event could be raised there.

At any rate, the answer to your question is you should implement INotifyPropertyChange. This interface contains the PropertyChanged event. Implementing INotifyPropertyChanged lets other code know that the class has the PropertyChanged event, so that code can hook up a handler. After implementing INotifyPropertyChange, the code that goes in the if statement of your OnPropertyChanged is:

if (PropertyChanged != null)
    PropertyChanged(new PropertyChangedEventArgs("MySecondProperty"));

You need

    str.CopyTo(data);
    data.Position = 0; // reset to beginning
    byte[] buf = new byte[data.Length];
    data.Read(buf, 0, buf.Length);  

And since your Test() method is imitating the client it ought to Close() or Dispose() the str Stream. And the memoryStream too, just out of principal.

There is a web-based project for this that is relatively early on called Pongo. It requires installing Python and some dependencies, but it should run on Windows.

I just changed project facet to 1.7 and it worked.

To have access to stuff provided by math module, like pi. You need to import the module first:

import math
print (math.pi)

This is what I use to get a consistent hash value:

    [uint32]$c = $null
    $crcTable = New-Object 'System.Uint32[]' 256

    for ($n = 0; $n -lt 256; $n++) {
        $c = [uint32]$n
        for ($k = 0; $k -lt 8; $k++) {
            if ($c -band 1) {
                $c = (0xEDB88320 -bxor ($c -shr 1))
            }
            else {
                $c = ($c -shr 1)
            }
        }
        $crcTable[$n] = $c
    }

    Write-Output $crcTable
}

function Update-Crc ([uint32]$crc, [byte[]]$buffer, [int]$length, $crcTable) {
    [uint32]$c = $crc

    for ($n = 0; $n -lt $length; $n++) {
        $c = ($crcTable[($c -bxor $buffer[$n]) -band 0xFF]) -bxor ($c -shr 8)
    }

    Write-Output $c
}

For anyone trying to run kafka on kubernetes and running into this error, this is what finally solved it for me:

You have to either:

1. Add hostname to the pod spec, that way kafka can find itself.

or

2. If using hostPort, then you need hostNetwork: true and dnsPolicy: ClusterFirstWithHostNet

The reason for this is because Kafka needs to talk to itself, and it decides to use the 'advertised' listener/hostname to find itself, rather than using localhost. Even if you have a Service that points the advertised host name at the pod, it is not visible from within the pod. I do not really know why that is the case, but at least there is a workaround.

There are also some properties you can set to force a control to fill its available space when it would otherwise not do so. For example, you can say:

HorizontalContentAlignment="Stretch"

... to force the contents of a control to stretch horizontally. Or you can say:

HorizontalAlignment="Stretch"

... to force the control itself to stretch horizontally to fill its parent.

Try putting display: block in the <li> tags instead of the <ul>

DENSE_RANK() is a rank with no gaps, i.e. it is “dense”.

select Name,EmailId,salary,DENSE_RANK() over(order by salary asc) from [dbo].[Employees]

RANK()-It contain gap between the rank.

select Name,EmailId,salary,RANK() over(order by salary asc) from [dbo].[Employees]

Determine if any string is a date

function checkIsAValidDate($myDateString){
    return (bool)strtotime($myDateString);
}

Iterating through this is the precise code that worked for me.

querySnapshot.docs.forEach((e) => {
   var readableDate = e.data().date.toDate();
   console.log(readableDate);
}

I don't know if you can automatically change the color, but you could exploit your loop to generate different colors:

for i in range(20):
   ax1.plot(x, y, color = (0, i / 20.0, 0, 1)

In this case, colors will vary from black to 100% green, but you can tune it if you want.

See the matplotlib plot() docs and look for the color keyword argument.

If you want to feed a list of colors, just make sure that you have a list big enough and then use the index of the loop to select the color

colors = ['r', 'b', ...., 'w']

for i in range(20):
   ax1.plot(x, y, color = colors[i])

EDIT: Per other comments, the "Advanced..." button appears to have been removed in more recent versions of Jenkins. If your version doesn't have it, see knorx's answer.

I had the same problem, and even after finding this old pull request I still had trouble finding where to specify the Workspace Root Directory or Build Record Root Directory at the system level, versus specifying a custom workspace for each job.

To set these:

1. Navigate to Jenkins -> Manage Jenkins -> Configure System
2. Right at the top, under Home directory, click the Advanced... button:
3. Now the fields for Workspace Root Directory and Build Record Root Directory appear:
4. The information that appears if you click the help bubbles to the left of each option is very instructive. In particular (from the Workspace Root Directory help):

   This value may include the following variables:

   • ${JENKINS_HOME} — Absolute path of the Jenkins home directory
   • ${ITEM_ROOTDIR} — Absolute path of the directory where Jenkins stores the configuration and related metadata for a given job
   • ${ITEM_FULL_NAME} — The full name of a given job, which may be slash-separated, e.g. foo/bar for the job bar in folder foo

   
   The value should normally include ${ITEM_ROOTDIR} or ${ITEM_FULL_NAME}, otherwise different jobs will end up sharing the same workspace.

Hi i tried to integrate with your code.

Can you have a look at this?

Thanks M.S

In my case I've to set Execute concurrent builds if necessary in job's General settings.

There is an extensive example of how to do this on javapractices.com. See in particular the Money class, which is meant to make monetary calculations simpler than using BigDecimal directly.

The design of this Money class is intended to make expressions more natural. For example:

if ( amount.lt(hundred) ) {
 cost = amount.times(price); 
}

The WEB4J tool has a similar class, called Decimal, which is a bit more polished than the Money class.

Here's my solution using generators:

For Maps:

let map1 = new Map(), map2 = new Map();

map1.set('a', 'foo');
map1.set('b', 'bar');
map2.set('b', 'baz');
map2.set('c', 'bazz');

let map3 = new Map(function*() { yield* map1; yield* map2; }());

console.log(Array.from(map3)); // Result: [ [ 'a', 'foo' ], [ 'b', 'baz' ], [ 'c', 'bazz' ] ]

For Sets:

let set1 = new Set(['foo', 'bar']), set2 = new Set(['bar', 'baz']);

let set3 = new Set(function*() { yield* set1; yield* set2; }());

console.log(Array.from(set3)); // Result: [ 'foo', 'bar', 'baz' ]

Have you looked at Android Developers Training on Zooming a View? Might be a good starting point.

You probably want to create a custom class extending DialogFragment to get this working.

Also, take a look at Jake Whartons NineOldAndroids for Honeycomb Animation API compatibility all the way back to API Level 1.

for those like me still stuck with SQL Server 2000, SET ROWCOUNT {number}; can be used before the UPDATE query

SET ROWCOUNT 100;
UPDATE Table SET ..;
SET ROWCOUNT 0;

will limit the update to 100 rows

It has been deprecated at least since SQL 2005, but as of SQL 2017 it still works. https://docs.microsoft.com/en-us/sql/t-sql/statements/set-rowcount-transact-sql?view=sql-server-2017

forfiles /p "v:" /s /m *.* /d -3 /c "cmd /c del @path"

You should do /d -3 (3 days earlier) This works fine for me. So all the complicated batches could be in the trash bin. Also forfiles don't support UNC paths, so make a network connection to a specific drive.

Try like this:

$data = array('current_login' => date('Y-m-d H:i:s'));
$this->db->set('last_login', 'current_login', false);
$this->db->where('id', 'some_id');
$this->db->update('login_table', $data);

Pay particular attention to the set() call's 3rd parameter. false prevents CodeIgniter from quoting the 2nd parameter -- this allows the value to be treated as a table column and not a string value. For any data that doesn't need to special treatment, you can lump all of those declarations into the $data array.

The query generated by above code:

UPDATE `login_table`
SET last_login = current_login, `current_login` = '2018-01-18 15:24:13'
WHERE `id` = 'some_id'

if a file is already being tracked by Git, adding the file to .gitignore won’t stop Git from tracking it. You’ll need to do git rm the offending file(s) first, then add to your .gitignore.

Adding .idea/ should work

To disable all rules on a specific line:

alert('foo'); // eslint-disable-line

I wrote a tool called who_attach_shm.pl, it parses /proc/[pid]/maps to get the information. you can download it from github

sample output:

https://github.com/yongjhih/CardView

A CardView v7 eclipse project. (from sdk/extras/android/m2repository/com/android/support/cardview-v7)

The project was built by steps:

cp {sdk}/extras/android/m2repository/com/android/support/cardview-v7/21.0.0-rc1/cardview-v7-21.0.0-rc1.aar cardview-v7-21.0.0-rc1.zip
unzip cardview-v7-21.0.0-rc1.zip
mkdir libs/
mv classes.jar libs/cardview-v7-21.0.0-rc1.jar

Just in case anyone still cares:

I had the same issue after copying a database directory directly using command

cp -r /path/to/my/database /var/lib/mysql/new_database

If you do this with a database that uses InnoDB tables, you will get this crazy 'table does not exist' error mentioned above.

The issue is that you need the ib* files in the root of the MySQL datadir (e.g. ibdata1, ib_logfile0 and ib_logfile1).

When I copied those it worked for me.

Super simple and readable, here's how you create a local proxy server to a local HTTP server with just Node.js (tested on v8.1.0). I've found it particular useful for integration testing so here's my share:

/**
 * Once this is running open your browser and hit http://localhost
 * You'll see that the request hits the proxy and you get the HTML back
 */

'use strict';

const net = require('net');
const http = require('http');

const PROXY_PORT = 80;
const HTTP_SERVER_PORT = 8080;

let proxy = net.createServer(socket => {
    socket.on('data', message => {
        console.log('---PROXY- got message', message.toString());

        let serviceSocket = new net.Socket();

        serviceSocket.connect(HTTP_SERVER_PORT, 'localhost', () => {
            console.log('---PROXY- Sending message to server');
            serviceSocket.write(message);
        });

        serviceSocket.on('data', data => {
            console.log('---PROXY- Receiving message from server', data.toString();
            socket.write(data);
        });
    });
});

let httpServer = http.createServer((req, res) => {
    switch (req.url) {
        case '/':
            res.writeHead(200, {'Content-Type': 'text/html'});
            res.end('<html><body><p>Ciao!</p></body></html>');
            break;
        default:
            res.writeHead(404, {'Content-Type': 'text/plain'});
            res.end('404 Not Found');
    }
});

proxy.listen(PROXY_PORT);
httpServer.listen(HTTP_SERVER_PORT);

Arbitrary Indentation of any Option

If you just want to indent random, arbitrary <option /> elements, you can use  , which has the greatest cross-browser compatibility of the solutions posted here...

.optionGroup {
  font-weight: bold;
  font-style: italic;
}

<select>
    <option class="optionGroup" selected disabled>Choose one</option>
    <option value="sydney" class="optionChild">&nbsp;&nbsp;&nbsp;&nbsp;Sydney</option>
    <option value="melbourne" class="optionChild">&nbsp;&nbsp;&nbsp;&nbsp;Melbourne</option>
    <option value="cromwell" class="optionChild">&nbsp;&nbsp;&nbsp;&nbsp;Cromwell</option>
    <option value="queenstown" class="optionChild">&nbsp;&nbsp;&nbsp;&nbsp;Queenstown</option>
</select>

Ordered Indentation of Options

But if you have some sorted, ordered structure to your data, then it is recommended that you use the <optgroup/> syntax....

The HTML element creates a grouping of options within a element. (Source: MDN Web Docs: <optgroup>)

<select>
    <optgroup label="Australia" default selected>
        <option value="sydney">Sydney</option>
        <option value="melbourne">Melbourne</option>
    </optgroup>
    <optgroup label="United Kingdom">
        <option value="london">London</option>
        <option value="glasgow">Glasgow</option>
    </optgroup>
</select>

Unfortunately, only one <optgroup /> level is allowed and currently supported by browsers today. (Source: w3.org.) Personally, I would consider that part of the spec broken, but you can always extend to third, fourth, etc., levels of indentation with using the   trick up above.

Put the query arguments in hidden input fields:

<form action="http://spufalcons.com/index.aspx">
    <input type="hidden" name="tab" value="gymnastics" />
    <input type="hidden" name="path" value="gym" />
    <input type="submit" value="SPU Gymnastics"/>
</form>

Just declare the enum outside the bounds of the class. Like this:

public enum card_suits
{
    Clubs,
    Hearts,
    Spades,
    Diamonds
}

public class Card
{
    ...
}

Remember that an enum is a type. You might also consider putting the enum in its own file if it's going to be used by other classes. (You're programming a card game and the suit is a very important attribute of the card that, in well-structured code, will need to be accessible by a number of classes.)

I use:

var lastPart = path.replace(/\\$/,'').split('\\').pop();

It replaces the last \ so it also works with folders.

Use -t on ls. e.g:.

ls -tr

or

ls -ltr

I had the same problem after I used the .gitignore file from https://github.com/github/gitignore/blob/master/Rails.gitignore

Everything worked out fine after I commented the following lines in the .gitignore file.

config/initializers/secret_token.rb
config/secrets.yml

I also have the same problem. Turned out I have the @PropertySource annotation set on the main Application class to read a different base properties file, so the normal "application.properties" is not used anymore.

POST Recipe with navigation to target page and reusable Blade file

dfsq's answer is very nice. I modified it a bit to fit my needs: I actually needed a modal for the case that, after clicking, the user would also be navigated to the corresponding page. Executing the query asynchronously is not always what one needs.

Using Blade I created the file resources/views/includes/confirmation_modal.blade.php:

<div class="modal fade" id="confirmation-modal" tabindex="-1" role="dialog" aria-labelledby="confirmation-modal-label" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <h4>{{ $headerText }}</h4>
            </div>
            <div class="modal-body">
                {{ $bodyText }}
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
                <form action="" method="POST" style="display:inline">
                    {{ method_field($verb) }}
                    {{ csrf_field() }}
                    <input type="submit" class="btn btn-danger btn-ok" value="{{ $confirmButtonText }}" />
                </form>
            </div>
        </div>
    </div>
</div>

<script>
    $('#confirmation-modal').on('show.bs.modal', function(e) {
        href = $(e.relatedTarget).data('href');

        // change href of button to corresponding target
        $(this).find('form').attr('action', href);
    });
</script>

Now, using it is straight-forward:

<a data-href="{{ route('data.destroy', ['id' => $data->id]) }}" data-toggle="modal" data-target="#confirmation-modal" class="btn btn-sm btn-danger">Remove</a>

Not much changed here and the modal can be included like this:

@include('includes.confirmation_modal', ['headerText' => 'Delete Data?', 'bodyText' => 'Do you really want to delete these data? This operation is irreversible.',
'confirmButtonText' => 'Remove Data', 'verb' => 'DELETE'])

Just by putting the verb in there, it uses it. This way, CSRF is also utilized.

Helped me, maybe it helps someone else.

I would add the CSS property of float left as seen below. That gets rid of the extra space.

ul li {
    float:left;
}

I tried all the solutions, none worked for me (using Swift 4), this is the solution that worked for me, if anyone in future faces the same problem.

let temp = base64String.components(separatedBy: ",")
let dataDecoded : Data = Data(base64Encoded: temp[1], options: 
 .ignoreUnknownCharacters)!
let decodedimage = UIImage(data: dataDecoded)

yourImage.image = decodedimage

This worked on my test file (note the index in VBA starts from zero):

Sub DV_Test()
    Dim ValidationList(5) As Variant, i As Integer

    For i = 0 To UBound(ValidationList)
        ValidationList(i) = i + 1
    Next

    With Range("A1").Validation
        .Delete
        .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
            Operator:=xlEqual, Formula1:=Join(ValidationList, ",")
        .IgnoreBlank = True
        .InCellDropdown = True
        .InputTitle = ""
        .ErrorTitle = ""
        .InputMessage = ""
        .ErrorMessage = ""
        .ShowInput = True
        .ShowError = True
    End With
End Sub

I used xlEqual because that's what I think you are trying to get people to select one of the list.

It tells the browser to read the css file as UTF-8. This is handy if your CSS contains unicode characters and not only ASCII.

Using it in the meta tag is fine, but only for pages that include that meta tag.

Read about the rules for character set resolution of CSS files at the w3c spec for CSS 2.

By using CHMOD yes:

For Recursive file:

chmod -R 777 foldername or pathname

For non recursive:

chmod 777 foldername or pathname

The real question is why does it generate a 500 error. If it is related to any input parameters, then I would argue that it should be handled internally and returned as a 400 series error. Generally a 400, 404 or 406 would be appropriate to reflect bad input since the general convention is that a RESTful resource is uniquely identified by the URL and a URL that cannot generate a valid response is a bad request (400) or similar.

If the error is caused by anything other than the inputs explicitly or implicitly supplied by the request, then I would say a 500 error is likely appropriate. So a failed database connection or other unpredictable error is accurately represented by a 500 series error.

if you're still having issues then update to the latest version of Android Studio(its 2.1 as of now), might be it was a bug with older version of Android Studio. Its resolved for me now.

The command [Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27", "User") is not a Python command. Instead, this is an operating system command to the set the PATH variable.

You are getting this error as you are inside the Python interpreter which was triggered by the command python you have entered in the terminal (Windows PowerShell).

Please note the >>> at the left side of the line. It states that you are on inside Python interpreter.

Please enter quit() to exit the Python interpreter and then type the command. It should work!

You can get to the root from within each site using $_SERVER['DOCUMENT_ROOT']. For testing ONLY you can echo out the path to make sure it's working, if you do it the right way. You NEVER want to show the local server paths for things like includes and requires.

Site 1

echo $_SERVER['DOCUMENT_ROOT']; //should be '/main_web_folder/';

Includes under site one would be at:

echo $_SERVER['DOCUMENT_ROOT'].'/includes/'; // should be '/main_web_folder/includes/';

Site 2

echo $_SERVER['DOCUMENT_ROOT']; //should be '/main_web_folder/blog/';

The actual code to access includes from site1 inside of site2 you would say:

include($_SERVER['DOCUMENT_ROOT'].'/../includes/file_from_site_1.php');

It will only use the relative path of the file executing the query if you try to access it by excluding the document root and the root slash:

 //(not as fool-proof or non-platform specific)
 include('../includes/file_from_site_1.php');

Included paths have no place in code on the front end (live) of the site anywhere, and should be secured and used in production environments only.

Additionally for URLs on the site itself you can make them relative to the domain. Browsers will automatically fill in the rest because they know which page they are looking at. So instead of:

<a href='http://www.__domain__name__here__.com/contact/'>Contact</a>

You should use:

<a href='/contact/'>Contact</a>

For good SEO you'll want to make sure that the URLs for the blog do not exist in the other domain, otherwise it may be marked as a duplicate site. With that being said you might also want to add a line to your robots.txt file for ONLY site1:

User-agent: *
Disallow: /blog/

Other possibilities:

Look up your IP address and include this snippet of code:

function is_dev(){
  //use the external IP from Google.
  //If you're hosting locally it's 127.0.01 unless you've changed it.
  $ip_address='xxx.xxx.xxx.xxx';

  if ($_SERVER['REMOTE_ADDR']==$ip_address){
     return true;
  } else {
     return false;
  } 
}

if(is_dev()){
    echo $_SERVER['DOCUMENT_ROOT'];       
}

Remember if your ISP changes your IP, as in you have a DCHP Dynamic IP, you'll need to change the IP in that file to see the results. I would put that file in an include, then require it on pages for debugging.

If you're okay with modern methods like using the browser console log you could do this instead and view it in the browser's debugging interface:

if(is_dev()){
    echo "<script>".PHP_EOL;
    echo "console.log('".$_SERVER['DOCUMENT_ROOT']."');".PHP_EOL;
    echo "</script>".PHP_EOL;       
}

Limit - 30 symbols. Username must contains only letters, numbers, periods and underscores.

An API is the interface through which you access someone elses code or through which someone else's code accesses yours. In effect the public methods and properties.

I've finally worked it out. The biggest issue is how they managed to work out what Wireless networks were around me and how do they know where these networks are.

It "seems" to be something similar to this:

1. skyhookwireless.com [or similar] Company has mapped the location of many wireless access points, i assume by similar means that google streetview went around and picked up all the photos.
2. Using Google gears and my browser, we can report which wireless networks i see and have around me
3. Compare these wireless points to their geolocation and triangulate my position.

In Chrome Ver 84, flex: 1 is equivalent to flex: 1 1 0%. The followings are a bunch of screenshots.

I know this is an old post, but another solution would be to use cURL, for example:

redirect.php:

<?php
if (isset($_GET['url'])) {
    $url = $_GET['url'];
    $ch = curl_init();
    $timeout = 5;
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    $data = curl_exec($ch);
    curl_close($ch);
    echo $data;
}

then in your iframe tag, something like:

<iframe src="/redirect.php?url=http://www.example.com/"></iframe>

This is just a MINIMAL example to illustrate the idea -- it doesn't sanitize the URL, nor would it prevent someone else using the redirect.php for their own purposes. Consider these things in the context of your own site.

The upside, though, is it's more flexible. For example, you could add some validation of the curl'd $data to make sure it's really what you want before displaying it -- for example, test to make sure it's not a 404, and have alternate content of your own ready if it is.

Plus -- I'm a little weary of relying on Javascript redirects for anything important.

Cheers!

No need to go in such deep technicalities, and get yourself blasted. Let me explain it in the most easiest way. We all have studied "Sets" during our school-age in Mathematics. Just consider 3D numpy array as the formation of "sets".

x = np.zeros((2,3,4)) 

Simply Means:

2 Sets, 3 Rows per Set, 4 Columns

Example:

Input

x = np.zeros((2,3,4))

Output

Set # 1 ---- [[[ 0.,  0.,  0.,  0.],  ---- Row 1
               [ 0.,  0.,  0.,  0.],  ---- Row 2
               [ 0.,  0.,  0.,  0.]], ---- Row 3 
    
Set # 2 ----  [[ 0.,  0.,  0.,  0.],  ---- Row 1
               [ 0.,  0.,  0.,  0.],  ---- Row 2
               [ 0.,  0.,  0.,  0.]]] ---- Row 3

Explanation: See? we have 2 Sets, 3 Rows per Set, and 4 Columns.

Note: Whenever you see a "Set of numbers" closed in double brackets from both ends. Consider it as a "set". And 3D and 3D+ arrays are always built on these "sets".

I don't know what things were like in the alpha, but I'm using beta 12 right now and this works fine. If you have an array of objects, create a select like this:

<select [(ngModel)]="simpleValue"> // value is a string or number
    <option *ngFor="let obj of objArray" [value]="obj.value">{{obj.name}}</option>
</select>

If you want to match on the actual object, I'd do it like this:

<select [(ngModel)]="objValue"> // value is an object
    <option *ngFor="let obj of objArray" [ngValue]="obj">{{obj.name}}</option>
</select>

I finally found the answer to my problem. The solution is

function load_home() {
     document.getElementById("content").innerHTML='<object type="text/html" data="home.html" ></object>';
}

UPDATE 
  receipt_invoices dest,
  (
    SELECT 
      `receipt_id`,
      CAST((net * 100) / 112 AS DECIMAL (11, 2)) witoutvat 
    FROM
      receipt 
    WHERE CAST((net * 100) / 112 AS DECIMAL (11, 2)) != total 
      AND vat_percentage = 12
  ) src 
SET
  dest.price = src.witoutvat,
  dest.amount = src.witoutvat 
WHERE col_tobefixed = 1 
  AND dest.`receipt_id` = src.receipt_id ;

Hope this will help you in a case where you have to match and update between two tables.

Not an answer to your question (which others have answered), but if you want to have some edit functionality of an uploaded file field, what you probably want to do is:

• show the current value of this field by just printing the filename or URL, a clickable link to download it, or if it's an image: just show it, possibly as thumbnail
• the <input> tag to upload a new file
• a checkbox that, when checked, deletes the currently uploaded file. note that there's no way to upload an 'empty' file, so you need something like this to clear out the field's value

You can use the overloaded constructor of DateTime:

DateTime utcDateTime = new DateTime(dateTime.Year, dateTime.Month, dateTime.Day, dateTime.Hour, dateTime.Minute, dateTime.Second, DateTimeKind.Utc);

It seems you may be more comfortable with developing in PHP you let this hold you back from utilizing the full potential with web applications.

It is indeed possible to have PHP render partials and whole views, but I would not recommend it.

To fully utilize the possibilities of HTML and javascript to make a web application, that is, a web page that acts more like an application and relies heavily on client side rendering, you should consider letting the client maintain all responsibility of managing state and presentation. This will be easier to maintain, and will be more user friendly.

I would recommend you to get more comfortable thinking in a more API centric approach. Rather than having PHP output a pre-rendered view, and use angular for mere DOM manipulation, you should consider having the PHP backend output the data that should be acted upon RESTFully, and have Angular present it.

Using PHP to render the view:

/user/account

if($loggedIn)
{
    echo "<p>Logged in as ".$user."</p>";
}
else
{
    echo "Please log in.";
}

How the same problem can be solved with an API centric approach by outputting JSON like this:

api/auth/

{
  authorized:true,
  user: {
      username: 'Joe', 
      securityToken: 'secret'
  }
}

and in Angular you could do a get, and handle the response client side.

$http.post("http://example.com/api/auth", {})
.success(function(data) {
    $scope.isLoggedIn = data.authorized;
});

To blend both client side and server side the way you proposed may be fit for smaller projects where maintainance is not important and you are the single author, but I lean more towards the API centric way as this will be more correct separation of conserns and will be easier to maintain.

Yes, MySQL allows this. You can have multiple foreign keys on the same table.

Usually I create Fowler's Range implementation for such things.

public interface IRange<T>
{
    T Start { get; }
    T End { get; }
    bool Includes(T value);
    bool Includes(IRange<T> range);
}

public class DateRange : IRange<DateTime>         
{
    public DateRange(DateTime start, DateTime end)
    {
        Start = start;
        End = end;
    }

    public DateTime Start { get; private set; }
    public DateTime End { get; private set; }

    public bool Includes(DateTime value)
    {
        return (Start <= value) && (value <= End);
    }

    public bool Includes(IRange<DateTime> range)
    {
        return (Start <= range.Start) && (range.End <= End);
    }
}

Usage is pretty simple:

DateRange range = new DateRange(startDate, endDate);
range.Includes(date)

Some extensions like blocksite use the accessibility service API to deploy extension like features to Chrome on Android. Might be worth a look through the play store. Otherwise, Firefox is your best bet, though many extensions don't work on mobile for some reason.

An example (axios_example.js) using Axios in Node.js:

const axios = require('axios');
const express = require('express');
const app = express();
const port = process.env.PORT || 5000;

app.get('/search', function(req, res) {
    let query = req.query.queryStr;
    let url = `https://your.service.org?query=${query}`;

    axios({
        method:'get',
        url,
        auth: {
            username: 'xxxxxxxxxxxxx',
            password: 'xxxxxxxxxxxxx'
        }
    })
    .then(function (response) {
        res.send(JSON.stringify(response.data));
    })
    .catch(function (error) {
        console.log(error);
    });
});

var server = app.listen(port);

Be sure in your project directory you do:

npm init
npm install express
npm install axios
node axios_example.js

You can then test the Node.js REST API using your browser at: http://localhost:5000/search?queryStr=xxxxxxxxx

You could run the data file through cat -v, e.g

$ cat -v tmp/test.log | grep re
line1 re ^@^M
line3 re^M

which could be then further post-processed to remove the junk; this is most analogous to your query about using tr for the task.

-v simply tells cat to display non-printing characters.

Can you load the GUIDs into a scratch table then do a

... WHERE var IN SELECT guid FROM #scratchtable

In my opinion, this is the simplest to read and understand:

StringBuilder sb = new StringBuilder();
for(String string : strings) {
    sb.append(string).append(',');
}
sb.setLength(sb.length() - 1);
String result = sb.toString();

Perhaps this is easier to read:

a2.all? { |e| a1.include?(e) }

You can also use array intersection:

(a1 & a2).size == a1.size

Note that size is used here just for speed, you can also do (slower):

(a1 & a2) == a1

But I guess the first is more readable. These 3 are plain ruby (not rails).

I suggest you step through the code in your debugger as debugging programs is what it is for.

What I would expect you would see is that every time the code loops int x = 0; is set.

I had trouble with touchend handler firing continuously while the user was dragging a finger around. I don't know if that's due to something I'm doing wrong or not but I rewired this to accumulate moves with touchmove and touchend actually fires the callback.

I also needed to have a large number of these instances and so I added enable/disable methods.

And a threshold where a short swipe doesn't fire. Touchstart zero's the counters each time.

You can change the target_node on the fly. Enable on creation is optional.

Sharing data between controllers is what Factories/Services are very good for. In short, it works something like this.

var app = angular.module('myApp', []);

app.factory('items', function() {
    var items = [];
    var itemsService = {};

    itemsService.add = function(item) {
        items.push(item);
    };
    itemsService.list = function() {
        return items;
    };

    return itemsService;
});

function Ctrl1($scope,items) {
    $scope.list = items.list; 
}

function Ctrl2($scope, items) {
    $scope.add = items.add;
}

Just A combination of these answers this And Roger

This is not "wrong" at all, it's just not what the cool guys typically do with MVC. As an aside, I wish some of the early demos of ASP.NET MVC didn't try to cram in Linq-to-Sql at the same time. It's pretty awesome and well suited for MVC, sure, but it's not required. There is nothing about MVC that prevents you from using ADO.NET. For example:

Controller action:

public ActionResult Index()
{
    ViewData["Message"] = "Welcome to ASP.NET MVC!";

    DataTable dt = new DataTable("MyTable");
    dt.Columns.Add(new DataColumn("Col1", typeof(string)));
    dt.Columns.Add(new DataColumn("Col2", typeof(string)));
    dt.Columns.Add(new DataColumn("Col3", typeof(string)));

    for (int i = 0; i < 3; i++)
    {
        DataRow row = dt.NewRow();
        row["Col1"] = "col 1, row " + i;
        row["Col2"] = "col 2, row " + i;
        row["Col3"] = "col 3, row " + i;
        dt.Rows.Add(row);
    }

    return View(dt); //passing the DataTable as my Model
}

View: (w/ Model strongly typed as System.Data.DataTable)

<table border="1">
    <thead>
        <tr>
            <%foreach (System.Data.DataColumn col in Model.Columns) { %>
                <th><%=col.Caption %></th>
            <%} %>
        </tr>
    </thead>
    <tbody>
    <% foreach(System.Data.DataRow row in Model.Rows) { %>
        <tr>
            <% foreach (var cell in row.ItemArray) {%>
                <td><%=cell.ToString() %></td>
            <%} %>
        </tr>
    <%} %>         
    </tbody>
</table>

Now, I'm violating a whole lot of principles and "best-practices" of ASP.NET MVC here, so please understand this is just a simple demonstration. The code creating the DataTable should reside somewhere outside of the controller, and the code in the View might be better isolated to a partial, or html helper, to name a few ways you should do things.

You absolutely are supposed to pass objects to the View, if the view is supposed to present them. (Separation of concerns dictates the view shouldn't be responsible for creating them.) In this case I passed the DataTable as the actual view Model, but you could just as well have put it in ViewData collection. Alternatively you might make a specific IndexViewModel class that contains the DataTable and other objects, such as the welcome message.

I hope this helps!

I have created a wrapper class based on Rustam Irzaev's answer with use of IWshRuntimeLibrary.

IWshRuntimeLibrary -> References -> COM > Windows Script Host Object Model

using System;
using System.IO;
using IWshRuntimeLibrary;
using File = System.IO.File;

{
    public static void CreateShortcut(string originalFilePathAndName, string destinationSavePath)
    {
        string fileName = Path.GetFileNameWithoutExtension(originalFilePathAndName);
        string originalFilePath = Path.GetDirectoryName(originalFilePathAndName);

        string link = destinationSavePath + Path.DirectorySeparatorChar + fileName + ".lnk";
        var shell = new WshShell();
        var shortcut = shell.CreateShortcut(link) as IWshShortcut;
        if (shortcut != null)
        {
            shortcut.TargetPath = originalFilePathAndName;
            shortcut.WorkingDirectory = originalFilePath;
            shortcut.Save();
        }
    }

    }

If you want all the dependencies in a single file at the end within two steps. Add this to your build.gradle.kts in the root of your project:

project.rootProject.allprojects {
    apply(plugin="project-report")

    this.task("allDependencies", DependencyReportTask::class) {
        evaluationDependsOnChildren()
        this.setRenderer(AsciiDependencyReportRenderer())
    }

}

Then apply:

./gradlew allDependencies | grep '\-\-\-' | grep -Po '\w+.*$' | awk -F ' ' '{ print $1 }' | sort | grep -v '\{' | grep -v '\[' | uniq | grep '.\+:.\+:.\+'

This will give you all the dependencies in your project and sub-projects along with all the 3rd party dependencies.

If you want to get this done in a programmatic way, then you'll need a custom renderer of the dependencies - you can start by extending the AsciiDependencyReportRenderer that prints an ascii graph of the dependencies by default.

You can use xsd as suggested by Darin.

In addition to that it is recommended to edit the test.xsd-file to create a more reasonable schema.

type="xs:string" can be changed to type="xs:int" for integer values
minOccurs="0" can be changed to minOccurs="1" where the field is required
maxOccurs="unbounded" can be changed to maxOccurs="1" where only one item is allowed

You can create more advanced xsd-s if you want to validate your data further, but this will at least give you reasonable data types in the generated c#.

The problem is that you used the select option, this is where you went wrong. Select signifies that a textbox or textArea has a focus. What you need to do is use change. "Fires when a new choice is made in a select element", also used like blur when moving away from a textbox or textArea.

function start(){
      document.getElementById("activitySelector").addEventListener("change", addActivityItem, false);
      }

function addActivityItem(){
      //option is selected
      alert("yeah");
}

window.addEventListener("load", start, false);

Use num_holes=None as a default, instead. Then check for whether num_holes is None, and if so, randomize. That's what I generally see, anyway.

More radically different construction methods may warrant a classmethod that returns an instance of cls.

memberOf (in AD) is stored as a list of distinguishedNames. Your filter needs to be something like:

(&(objectCategory=user)(memberOf=cn=MyCustomGroup,ou=ouOfGroup,dc=subdomain,dc=domain,dc=com))

If you don't yet have the distinguished name, you can search for it with:

(&(objectCategory=group)(cn=myCustomGroup))

and return the attribute distinguishedName. Case may matter.

I ran into this problem while upgrading to WordPress 4.0. By default WordPress limits the maximum execution time to 30 seconds.

Add the following code to your .htaccess file on your root directory of your WordPress Installation to over-ride the default.

php_value max_execution_time 300  //where 300 = 300 seconds = 5 minutes

You can call a stored procedure from another stored procedure by using the EXECUTE command.

Say your procedure is X. Then in X you can use

EXECUTE PROCEDURE Y () RETURNING_VALUES RESULT;"

You can try this modal:https://github.com/xue2han/react-dynamic-modal It is stateless and can be rendered only when needed.So it is very easy to use.Just like this:

    class MyModal extends Component{
       render(){
          const { text } = this.props;
          return (
             <Modal
                onRequestClose={this.props.onRequestClose}
                openTimeoutMS={150}
                closeTimeoutMS={150}
                style={customStyle}>
                <h1>What you input : {text}</h1>
                <button onClick={ModalManager.close}>Close Modal</button>
             </Modal>
          );
       }
    }

    class App extends Component{
        openModal(){
           const text = this.refs.input.value;
           ModalManager.open(<MyModal text={text} onRequestClose={() => true}/>);
        }
        render(){
           return (
              <div>
                <div><input type="text" placeholder="input something" ref="input" /></div>
                <div><button type="button" onClick={this.openModal.bind(this)}>Open Modal </button> </div>
              </div>
           );
        }
    }

    ReactDOM.render(<App />,document.getElementById('main'));

Dim originally (in BASIC) stood for Dimension, as it was used to define the dimensions of an array.

(The original implementation of BASIC was Dartmouth BASIC, which descended from FORTRAN, where DIMENSION is spelled out.)

Nowadays, Dim is used to define any variable, not just arrays, so its meaning is not intuitive anymore.

We also faced the same issue, and the problem could only be reproduced in the server (i.e., not locally, which made it even harder to fix, because we could not debug the application), and when using IE. We had a page with an update panel, and within this update panel a modalpopupextender, which also contained an update panel. After trying several solutions that did not work, we fix it by replacing every imagebutton within the modalpopupextender with a linkbutton, and within it the image needed.

Use numeric(n,n) where n has enough resolution to round to 1.00. For instance:

declare @discount numeric(9,9)
    , @quantity int
select @discount = 0.999999999
    , @quantity = 10000

select convert(money, @discount * @quantity)

When using Auto Layout in code, setting the frame does nothing. So the fact that you specified a width of 200 on the view above, doesn't mean anything when you set constraints on it. In order for a view's constraint set to be unambiguous, it needs four things: an x-position, a y-position, a width, and a height for any given state.

Currently in the code above, you only have two (height, relative to the superview, and y-position, relative to the superview). In addition to this, you have two required constraints that could conflict depending on how the view's superview's constraints are setup. If the superview were to have a required constraint that specifies it's height be some value less than 748, you will get an "unsatisfiable constraints" exception.

The fact that you've set the width of the view before setting constraints means nothing. It will not even take the old frame into account and will calculate a new frame based on all of the constraints that it has specified for those views. When dealing with autolayout in code, I typically just create a new view using initWithFrame:CGRectZero or simply init.

To create the constraint set required for the layout you verbally described in your question, you would need to add some horizontal constraints to bound the width and x-position in order to give a fully-specified layout:

[self.view addConstraints:[NSLayoutConstraint
    constraintsWithVisualFormat:@"V:|-[myView(>=748)]-|"
    options:NSLayoutFormatDirectionLeadingToTrailing
    metrics:nil
    views:NSDictionaryOfVariableBindings(myView)]];

[self.view addConstraints:[NSLayoutConstraint
    constraintsWithVisualFormat:@"H:[myView(==200)]-|"
    options:NSLayoutFormatDirectionLeadingToTrailing
    metrics:nil
    views:NSDictionaryOfVariableBindings(myView)]];

Verbally describing this layout reads as follows starting with the vertical constraint:

myView will fill its superview's height with a top and bottom padding equal to the standard space. myView's superview has a minimum height of 748pts. myView's width is 200pts and has a right padding equal to the standard space against its superview.

If you would simply like the view to fill the entire superview's height without constraining the superview's height, then you would just omit the (>=748) parameter in the visual format text. If you think that the (>=748) parameter is required to give it a height - you don't in this instance: pinning the view to the superview's edges using the bar (|) or bar with space (|-, -|) syntax, you are giving your view a y-position (pinning the view on a single-edge), and a y-position with height (pinning the view on both edges), thus satisfying your constraint set for the view.

In regards to your second question:

Using NSDictionaryOfVariableBindings(self.myView) (if you had an property setup for myView) and feeding that into your VFL to use self.myView in your VFL text, you will probably get an exception when autolayout tries to parse your VFL text. It has to do with the dot notation in dictionary keys and the system trying to use valueForKeyPath:. See here for a similar question and answer.

I have got an error on the first answer so I have changed some code line.

FundraiserStudentListModel here:

 public class FundraiserStudentListModel
{
    public string Name { get; set; }
    public string Email { get; set; }
    public string Phone { get; set; }
}

you can also use the class name.

In python notebooks I often want to filter out 'dangling' numpy.ndarray's, in particular the ones that are stored in _1, _2, etc that were never really meant to stay alive.

I use this code to get a listing of all of them and their size.

Not sure if locals() or globals() is better here.

import sys
import numpy
from humanize import naturalsize

for size, name in sorted(
    (value.nbytes, name)
    for name, value in locals().items()
    if isinstance(value, numpy.ndarray)):
  print("{:>30}: {:>8}".format(name, naturalsize(size)))

Note that Math.hypot is part of the ES2015 standard. There's also a good polyfill on the MDN doc for this feature.

So getting the distance becomes as easy as Math.hypot(x2-x1, y2-y1).

Documentation: https://docs.python.org/3/library/copy.html

Tested on Python 3.6.5.

Here's a sample method that adds two extra columns programmatically to the grid view:

    private void AddColumnsProgrammatically()
    {
        // I created these columns at function scope but if you want to access 
        // easily from other parts of your class, just move them to class scope.
        // E.g. Declare them outside of the function...
        var col3 = new DataGridViewTextBoxColumn();
        var col4 = new DataGridViewCheckBoxColumn();

        col3.HeaderText = "Column3";
        col3.Name = "Column3";

        col4.HeaderText = "Column4";
        col4.Name = "Column4";

        dataGridView1.Columns.AddRange(new DataGridViewColumn[] {col3,col4});
    }

A great way to figure out how to do this kind of process is to create a form, add a grid view control and add some columns. (This process will actually work for ANY kind of form control. All instantiation and initialization happens in the Designer.) Then examine the form's Designer.cs file to see how the construction takes place. (Visual Studio does everything programmatically but hides it in the Form Designer.)

For this example I created two columns for the view named Column1 and Column2 and then searched Form1.Designer.cs for Column1 to see everywhere it was referenced. The following information is what I gleaned and, copied and modified to create two more columns dynamically:

// Note that this info scattered throughout the designer but can easily collected.

        System.Windows.Forms.DataGridViewTextBoxColumn Column1;
        System.Windows.Forms.DataGridViewCheckBoxColumn Column2;

        this.Column1 = new System.Windows.Forms.DataGridViewTextBoxColumn();
        this.Column2 = new System.Windows.Forms.DataGridViewCheckBoxColumn();

        this.dataGridView1.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] {
        this.Column1,
        this.Column2});

        this.Column1.HeaderText = "Column1";
        this.Column1.Name = "Column1";

        this.Column2.HeaderText = "Column2";
        this.Column2.Name = "Column2";

I think that the solution of @Azimuts (https://stackoverflow.com/a/33375677/6503697) is for HTTP only connection. For FTPS connection you can use Bouncy Castle with org.apache.commons.net.ftp.FTPSClient without the need for rewrite FTPS protocol.

I have a program running on JRE 1.6.0_04 and I can not update the JRE.

The program has to connect to an FTPS server that work only with TLS 1.2 (IIS server).

I struggled for days and finally I have understood that there are few versions of bouncy castle library right in my use case: bctls-jdk15on-1.60.jar and bcprov-jdk15on-1.60.jar are ok, but 1.64 versions are not.

The version of apache commons-net is 3.1 .

Following is a small snippet of code that should work:

    }

    public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {
    }

    public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {
    }
} };

    org.apache.commons.net.ftp.FTPSClient ftpClient = new FTPSClient(sslContext);
    ByteArrayOutputStream out = null;
    try {

        ftpClient.connect("hostaname", 21);
        if (!FTPReply.isPositiveCompletion(ftpClient.getReplyCode())) {
            String msg = "Il server ftp ha rifiutato la connessione.";
            throw new Exception(msg);
        }
        if (!ftpClient.login("username", "pwd")) {
            String msg = "Il server ftp ha rifiutato il login con username:  username  e pwd:  password  .";
            ftpClient.disconnect();
            throw new Exception(msg);
        }


        ftpClient.enterLocalPassiveMode();
        ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
        ftpClient.setDataTimeout(60000);
        ftpClient.execPBSZ(0); // Set protection buffer size
        ftpClient.execPROT("P"); // Set data channel protection to private
        int bufSize = 1024 * 1024; // 1MB
        ftpClient.setBufferSize(bufSize);
        out = new ByteArrayOutputStream(bufSize);
        ftpClient.retrieveFile("remoteFileName", out);
        out.toByteArray();
    }
    finally {
        if (out != null) {
            out.close();
        }
        ftpClient.disconnect();

Thank you @mfitzp. In my case (CentOS) these libs are not available in the yum repo, but actually the solution was even easier. What I did:

sudo yum install python-devel
sudo yum install zlib-devel
sudo yum install libjpeg-turbo-devel

And now pillow's installation finishes successfully.

This below code will give selected row, you can parse the values from it and send to the AJAX call.

$(".selected").click(function () {
var row = $(this).parent().parent().parent().html();            
});

You are checking whether the string contains all illegal characters. Change the ||s to &&s.

Use the :not pseudo-class to exclude the classes you don't want the hover to apply to:

.test:not(.nohover):hover {  
    border: 1px solid red; 
}

This does what you want in one css rule!

Not so graceful, but the very much simple in implementation solution - using global variable.

In the "first" file:

window.myApp = angular.module("myApp", [])
....

in the "second" , "third", etc:

myApp.controller('MyController', function($scope) {
    .... 
    }); 

I needed a common event handler in which I can show from which button it is called without using switch case... and done like this..

  Private Sub btn_done_clicked(ByVal sender As System.Object, ByVal e As System.EventArgs)

    MsgBox.Show("you have clicked button " & CType(CType(sender,  _
    System.Windows.Forms.Button).Tag, String))

  End Sub

Fix urlpatterns in urls.py file

For example, my app name is "simulator",

My URL pattern for login and logout looks like

urlpatterns = [
    ...
    ...
    url(r'^login/$', simulator.views.login_view, name="login"),
    url(r'^logout/$', simulator.views.logout_view, name="logout"),
    ...
    ...

]

You don't really need it today, because the current standard makes it optional -- and every useful browser currently assumes that a style sheet is CSS, even in versions of HTML that considered the attribute "required".

With HTML being a "living standard" now, though -- and thus subject to change -- you can only guarantee so much. And there's no new DTD that you can point to and say the page was written for that version of HTML, and no reliable way even to say "HTML as of such-and-such a date". For forward-compatibility reasons, in my opinion, you should specify the type.

you can use DateUtils class in org.apache.commons.lang3.time package

int addMinuteTime = 5;
Date targetTime = new Date(); //now
targetTime = DateUtils.addMinutes(targetTime, addMinuteTime); //add minute

I suggest Validator.nu's parser, based on the HTML5 parsing algorithm. It is the parser used in Mozilla from 2010-05-03

In VB.NET, you can apply multiple conditions even if the other conditions don't apply to the Select parameter. See below:

Select Case parameter 
    Case "userID"
                ' does something here.
        Case "packageID"
                ' does something here.
        Case "mvrType" And otherFactor
                ' does something here. 
        Case Else 
                ' does some processing... 
End Select

Another way to do this, if you're in a hurry and don't mind the hacky-aftertaste, is to execute the output of the python script in your bash environment and print out the commands to execute setting the environment in python. Not ideal but it can get the job done in a pinch. It's not very portable across shells, so YMMV.

$(python -c 'print "export MY_DATA=my_export"')

(you can also enclose the statement in backticks in some shells ``)

Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

This solved my problem

    String inputText = "some text with escaped chars"
    InputStream is = new ByteArrayInputStream(inputText.getBytes("UTF-8"));

this.$('#datepicker').datepicker({minDate: 1});

minDate:0 - Enable dates in the calender from the current date. MinDate:1 enable dates in the calender currentDate+1

To Restrict date between from tomorrow and the same day next month u need to give something like

$( "#datepicker" ).datepicker({ minDate: 1, maxDate: "+1M" });

This answer is merged from another question.

Your getAge() method is called instance method in Java.

To invoke an instance method, you should have a object of the Class in which this method is defined.

For Example, If this method in a Class called Person, then

1. Create a Person object using new operator

    Person p = new Person();
   

2. To get the age of a Person object, use this method

   p.getAge()
   

It's ES6 Spread_operator and Destructuring_assignment.

<div {...this.props}>
  Content Here
</div>

It's equal to Class Component

const person = {
    name: "xgqfrms",
    age: 23,
    country: "China"
};

class TestDemo extends React.Component {
    render() {
        const {name, age, country} = {...this.props};
        // const {name, age, country} = this.props;
        return (
          <div>
              <h3> Person Information: </h3>
              <ul>
                <li>name={name}</li>
                <li>age={age}</li>
                <li>country={country}</li>
              </ul>
          </div>
        );
    }
}

ReactDOM.render(
    <TestDemo {...person}/>
    , mountNode
);

or Function component

const props = {
    name: "xgqfrms",
    age: 23,
    country: "China"
};

const Test = (props) => {
  return(
    <div
        name={props.name}
        age={props.age}
        country={props.country}>
        Content Here
        <ul>
          <li>name={props.name}</li>
          <li>age={props.age}</li>
          <li>country={props.country}</li>
        </ul>
    </div>
  );
};

ReactDOM.render(
    <div>
        <Test {...props}/>
        <hr/>
        <Test 
            name={props.name}
            age={props.age}
            country={props.country}
        />
    </div>
    , mountNode
);

If you have a package.json, you can install all the current project dependencies using:

npm install

Here is a piece of my Android app's code:

This app is able to communicate with a HTTP get-post model between a servlet running on a server and an Android device plugged in USB-Debuggable mode (because the app was in developing progress).

I also can run the app over Wi-Fi when the server, Tomcat Apache 7, running on (when the app development was finished).

To get the IP address of yours

1. Go to Command Prompt
2. Type ipconfig
3. Hit enter

In the list, IPv4 Address is your IP.

Here's a slightly more flexible approach using the match method. With this, you can extract more than one string:

s = "<ants> <pants>"
matchdata = s.match(/<([^>]*)> <([^>]*)>/)

# Use 'captures' to get an array of the captures
matchdata.captures   # ["ants","pants"]

# Or use raw indices
matchdata[0]   # whole regex match: "<ants> <pants>"
matchdata[1]   # first capture: "ants"
matchdata[2]   # second capture: "pants"

this worked for me.

Expanding on @Kazetsukai's answer, you may run into this problem if you are making your AJAX request from the user clicking on a link.

If you set up your link like so:

<a href="#" onclick="soAjax()">click me!</a>

And then a javascript handler like the following:

soAjax() {
    $.ajax({ ... all your lovely parameters ... });       
}

To prevent your browser from following the link and cancelling any requests in progress, you should add return false or e.preventDefault() to stop the click event from propagating:

soAjax() {
   $.ajax({ ... etc ... });
   return false;
}

Or:

soAjax(e) {
   $.ajax({ ... etc ... });
   e.preventDefault();
}

If you've tried some of the suggestions in the other answers, most notably:

• David Brabant's answer: confirming the Windows Management Instrumentation (WMI) inbound firewall rule is enabled
• Abhi_Mishra's answer: confirming DCOM is enabled in the Registry

Then consider other common reasons for getting this error:

• The remote machine is OFF
• You specified an invalid computer name
• There are network connectivity problems between you and the target computer

× is better than ✖ as ✖ behaves strangely in Edge and Internet explorer (tested in IE11). It doesn't get the right color and is replaced by an "emoji"

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

If you're running a single node cluster for some reason, you might simply need to do avoid replicas, like this:

curl -XPUT -H 'Content-Type: application/json' 'localhost:9200/_settings' -d '
{
    "index" : {
        "number_of_replicas" : 0
    }
}'

Doing this you'll force to use es without replicas

I would like to answer this question as this comes all times up in searches --

You can call a controller method in view, but please note that this is not a good practice in any MVC including codeigniter.

Your controller may be like below class --

<?php
    class VCI_Controller extends CI_Controller {
    ....
    ....
    function abc($id){
       return $id ;
    }

    }
?>

Now You can call this function in view files as below --
<?php
    $CI =& get_instance();
    $CI->abc($id) ;

?>

in cmd set Visual Studio path depending upon ur version as

Visual Studio 2010 (VS10): SET VS90COMNTOOLS=%VS100COMNTOOLS%

Visual Studio 2012 (VS11): SET VS90COMNTOOLS=%VS110COMNTOOLS%

Visual Studio 2013 (VS12): SET VS90COMNTOOLS=%VS120COMNTOOLS%

In node-master( original node module downloaded from git ) run vcbuild.bat with admin privileges. vcbild.bat will generate windows related dependencies and will add folder name Release in node-master

Once it run it will take time to build the files.

Then in the directory having .gyp file use command

node-gyp rebuild --msvs_version=2012 --nodedir="Dive Name:\path to node-master\node-master"

this will build all the dependencies.

I think what you are looking for is this:

public class Ques2 {

/**
 * @param args the command line arguments
 */
public static void main(String[] args) throws IOException {
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    String input = br.readLine().toLowerCase();
    StringBuilder result = new StringBuilder();
    char currentCharacter;
    int count;

    for (int i = 0; i < input.length(); i++) {
        currentCharacter = input.charAt(i);
        count = 1;
        while (i < input.length() - 1 && input.charAt(i + 1) == currentCharacter) {
            count++;
            i++;
        }
        result.append(currentCharacter);
        result.append(count);
    }

    System.out.println("" + result);
}

}

This was a bug fixed in version 4.3.11 https://hibernate.atlassian.net/browse/HHH-2851

EDIT: Best way to execute a native query is still to use NamedParameterJdbcTemplate It allows you need to retrieve a result that is not a managed entity ; you can use a RowMapper and even a Map of named parameters!

private NamedParameterJdbcTemplate namedParameterJdbcTemplate;

@Autowired
public void setDataSource(DataSource dataSource) {
    this.namedParameterJdbcTemplate = new NamedParameterJdbcTemplate(dataSource);
}

final List<Long> resultList = namedParameterJdbcTemplate.query(query, 
            mapOfNamedParamters, 
            new RowMapper<Long>() {
        @Override
        public Long mapRow(ResultSet rs, int rowNum) throws SQLException {
            return rs.getLong(1);
        }
    });

cout.fill('*');
cout << -12345 << endl; // print default value with no field width
cout << setw(10) << -12345 << endl; // print default with field width
cout << setw(10) << left << -12345 << endl; // print left justified
cout << setw(10) << right << -12345 << endl; // print right justified
cout << setw(10) << internal << -12345 << endl; // print internally justified

This produces the output:

-12345
****-12345
-12345****
****-12345
-****12345

I had a similar problem, too: I wanted numbers and null on an input field that is not required. Worked through a number of different variations. I finally settled on this one, which seems to do the trick. You place a Directive, ntvFormValidity, on any form control that has native invalidity and that doesn't swizzle that invalid state into ng-invalid.

Sample use: <input type="number" formControlName="num" placeholder="0" ntvFormValidity>

Directive definition:

import { Directive, Host, Self, ElementRef, AfterViewInit } from '@angular/core';
import { FormControlName, FormControl, Validators } from '@angular/forms';

@Directive({
  selector: '[ntvFormValidity]'
})
export class NtvFormControlValidityDirective implements AfterViewInit {

  constructor(@Host() private cn: FormControlName, @Host() private el: ElementRef) { }

  /* 
  - Angular doesn't fire "change" events for invalid <input type="number">
  - We have to check the DOM object for browser native invalid state
  - Add custom validator that checks native invalidity
  */
  ngAfterViewInit() {
    var control: FormControl = this.cn.control;

    // Bridge native invalid to ng-invalid via Validators
    const ntvValidator = () => !this.el.nativeElement.validity.valid ? { error: "invalid" } : null;
    const v_fn = control.validator;

    control.setValidators(v_fn ? Validators.compose([v_fn, ntvValidator]) : ntvValidator);
    setTimeout(()=>control.updateValueAndValidity(), 0);
  }
}

The challenge was to get the ElementRef from the FormControl so that I could examine it. I know there's @ViewChild, but I didn't want to have to annotate each numeric input field with an ID and pass it to something else. So, I built a Directive which can ask for the ElementRef.

On Safari, for the HTML example above, Angular marks the form control invalid on inputs like "abc".

I think if I were to do this over, I'd probably build my own CVA for numeric input fields as that would provide even more control and make for a simple html.

Something like this:

<my-input-number formControlName="num" placeholder="0">

PS: If there's a better way to grab the FormControl for the directive, I'm guessing with Dependency Injection and providers on the declaration, please let me know so I can update my Directive (and this answer).

Proper HTML way: just surround your button with anchor element and add attribute target="_blank". It is as simple as that:

<a ng-href="{{yourDynamicURL}}" target="_blank">
    <h1>Open me in new Tab</h1>
</a>

where you can set in the controller:

$scope.yourDynamicURL = 'https://stackoverflow.com';

You can do it with an UPDATE statement setting the value with a REPLACE

UPDATE
    Table
SET
    Column = Replace(Column, 'find value', 'replacement value')
WHERE
    xxx

You will want to be extremely careful when doing this! I highly recommend doing a backup first.

It is now officially supported by Facebook. Just select the 'Button' layout.

First and foremost, the "pass by value vs. pass by reference" distinction as defined in the CS theory is now obsolete because the technique originally defined as "pass by reference" has since fallen out of favor and is seldom used now.¹

Newer languages² tend to use a different (but similar) pair of techniques to achieve the same effects (see below) which is the primary source of confusion.

A secondary source of confusion is the fact that in "pass by reference", "reference" has a narrower meaning than the general term "reference" (because the phrase predates it).

Now, the authentic definition is:

• When a parameter is passed by reference, the caller and the callee use the same variable for the parameter. If the callee modifies the parameter variable, the effect is visible to the caller's variable.

• When a parameter is passed by value, the caller and callee have two independent variables with the same value. If the callee modifies the parameter variable, the effect is not visible to the caller.

Things to note in this definition are:

• "Variable" here means the caller's (local or global) variable itself -- i.e. if I pass a local variable by reference and assign to it, I'll change the caller's variable itself, not e.g. whatever it is pointing to if it's a pointer.

  • This is now considered bad practice (as an implicit dependency). As such, virtually all newer languages are exclusively, or almost exclusively pass-by-value. Pass-by-reference is now chiefly used in the form of "output/inout arguments" in languages where a function cannot return more than one value.

• The meaning of "reference" in "pass by reference". The difference with the general "reference" term is that this "reference" is temporary and implicit. What the callee basically gets is a "variable" that is somehow "the same" as the original one. How specifically this effect is achieved is irrelevant (e.g. the language may also expose some implementation details -- addresses, pointers, dereferencing -- this is all irrelevant; if the net effect is this, it's pass-by-reference).

Now, in modern languages, variables tend to be of "reference types" (another concept invented later than "pass by reference" and inspired by it), i.e. the actual object data is stored separately somewhere (usually, on the heap), and only "references" to it are ever held in variables and passed as parameters.³

Passing such a reference falls under pass-by-value because a variable's value is technically the reference itself, not the referred object. However, the net effect on the program can be the same as either pass-by-value or pass-by-reference:

• If a reference is just taken from a caller's variable and passed as an argument, this has the same effect as pass-by-reference: if the referred object is mutated in the callee, the caller will see the change.
  • However, if a variable holding this reference is reassigned, it will stop pointing to that object, so any further operations on this variable will instead affect whatever it is pointing to now.
• To have the same effect as pass-by-value, a copy of the object is made at some point. Options include:
  • The caller can just make a private copy before the call and give the callee a reference to that instead.
  • In some languages, some object types are "immutable": any operation on them that seems to alter the value actually creates a completely new object without affecting the original one. So, passing an object of such a type as an argument always has the effect of pass-by-value: a copy for the callee will be made automatically if and when it needs a change, and the caller's object will never be affected.
    • In functional languages, all objects are immutable.

As you may see, this pair of techniques is almost the same as those in the definition, only with a level of indirection: just replace "variable" with "referenced object".

There's no agreed-upon name for them, which leads to contorted explanations like "call by value where the value is a reference". In 1975, Barbara Liskov suggested the term "call-by-object-sharing" (or sometimes just "call-by-sharing") though it never quite caught on. Moreover, neither of these phrases draws a parallel with the original pair. No wonder the old terms ended up being reused in the absence of anything better, leading to confusion.⁴

NOTE: For a long time, this answer used to say:

Say I want to share a web page with you. If I tell you the URL, I'm passing by reference. You can use that URL to see the same web page I can see. If that page is changed, we both see the changes. If you delete the URL, all you're doing is destroying your reference to that page - you're not deleting the actual page itself.

If I print out the page and give you the printout, I'm passing by value. Your page is a disconnected copy of the original. You won't see any subsequent changes, and any changes that you make (e.g. scribbling on your printout) will not show up on the original page. If you destroy the printout, you have actually destroyed your copy of the object - but the original web page remains intact.

This is mostly correct except the narrower meaning of "reference" -- it being both temporary and implicit (it doesn't have to, but being explicit and/or persistent are additional features, not a part of the pass-by-reference semantic, as explained above). A closer analogy would be giving you a copy of a document vs inviting you to work on the original.

¹_{Unless you are programming in Fortran or Visual Basic, it's not the default behavior, and in most languages in modern use, true call-by-reference is not even possible.}

²_{A fair amount of older ones support it, too}

³_{In several modern languages, all types are reference types. This approach was pioneered by the language CLU in 1975 and has since been adopted by many other languages, including Python and Ruby. And many more languages use a hybrid approach, where some types are "value types" and others are "reference types" -- among them are C#, Java, and JavaScript.}

⁴_{There's nothing bad with recycling a fitting old term per se, but one has to somehow make it clear which meaning is used each time. Not doing that is exactly what keeps causing confusion.}

Honestly, I was in the same boat as you. I've got a C++ Library that I wanted to connect to a graphing utility. I ended up using Boost Python and matplotlib. It was the best one that I could find.

As a side note: I was also wary of licensing. matplotlib and the boost libraries can be integrated into proprietary applications.

Here's an example of the code that I used:

#include <boost/python.hpp>
#include <pygtk/pygtk.h>
#include <gtkmm.h>

using namespace boost::python;
using namespace std;

// This is called in the idle loop.
bool update(object *axes, object *canvas) {
    static object random_integers = object(handle<>(PyImport_ImportModule("numpy.random"))).attr("random_integers");
    axes->attr("scatter")(random_integers(0,1000,1000), random_integers(0,1000,1000));
    axes->attr("set_xlim")(0,1000);
    axes->attr("set_ylim")(0,1000);
    canvas->attr("draw")();
    return true;
}

int main() {
    try {
        // Python startup code
        Py_Initialize();
        PyRun_SimpleString("import signal");
        PyRun_SimpleString("signal.signal(signal.SIGINT, signal.SIG_DFL)");

        // Normal Gtk startup code
        Gtk::Main kit(0,0);

        // Get the python Figure and FigureCanvas types.
        object Figure = object(handle<>(PyImport_ImportModule("matplotlib.figure"))).attr("Figure");
        object FigureCanvas = object(handle<>(PyImport_ImportModule("matplotlib.backends.backend_gtkagg"))).attr("FigureCanvasGTKAgg");

        // Instantiate a canvas
        object figure = Figure();
        object canvas = FigureCanvas(figure);
        object axes = figure.attr("add_subplot")(111);
        axes.attr("hold")(false);

        // Create our window.
        Gtk::Window window;
        window.set_title("Engineering Sample");
        window.set_default_size(1000, 600);

        // Grab the Gtk::DrawingArea from the canvas.
        Gtk::DrawingArea *plot = Glib::wrap(GTK_DRAWING_AREA(pygobject_get(canvas.ptr())));

        // Add the plot to the window.
        window.add(*plot);
        window.show_all();

        // On the idle loop, we'll call update(axes, canvas).
        Glib::signal_idle().connect(sigc::bind(&update, &axes, &canvas));

        // And start the Gtk event loop.
        Gtk::Main::run(window);

    } catch( error_already_set ) {
        PyErr_Print();
    }
}

No you don't have to put credentials, You have to put headers on client side eg:

 $http({
        url: 'url of service',
        method: "POST",
        data: {test :  name },
        withCredentials: true,
        headers: {
                    'Content-Type': 'application/json; charset=utf-8'
        }
    });

And and on server side you have to put headers to this is example for nodejs:

/**
 * On all requests add headers
 */
app.all('*', function(req, res,next) {


    /**
     * Response settings
     * @type {Object}
     */
    var responseSettings = {
        "AccessControlAllowOrigin": req.headers.origin,
        "AccessControlAllowHeaders": "Content-Type,X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5,  Date, X-Api-Version, X-File-Name",
        "AccessControlAllowMethods": "POST, GET, PUT, DELETE, OPTIONS",
        "AccessControlAllowCredentials": true
    };

    /**
     * Headers
     */
    res.header("Access-Control-Allow-Credentials", responseSettings.AccessControlAllowCredentials);
    res.header("Access-Control-Allow-Origin",  responseSettings.AccessControlAllowOrigin);
    res.header("Access-Control-Allow-Headers", (req.headers['access-control-request-headers']) ? req.headers['access-control-request-headers'] : "x-requested-with");
    res.header("Access-Control-Allow-Methods", (req.headers['access-control-request-method']) ? req.headers['access-control-request-method'] : responseSettings.AccessControlAllowMethods);

    if ('OPTIONS' == req.method) {
        res.send(200);
    }
    else {
        next();
    }


});

If you don't want to go through the hassle of adding orientation in each manifest entry of activity better, create a BaseActivity class (inherits 'Activity' or 'AppCompatActivity') which will be inherited by every activity of your application instead of 'Activity' or 'AppCompatActivity' and just add the following piece of code in your BaseActivity:

@Override

in 2020, the accepted answer is kinda out of date since the PageRequest is deprecated, so you should use code like this :

Pageable page = PageRequest.of(pageable.getPageNumber(), pageable.getPageSize(), Sort.by("id").descending());
return repository.findAll(page);

In makefile language $@ means "name of the target", so rm -f $@ translates to rm -f clean.

You need to specify to rm what exactly you want to delete, like rm -f *.o code1 code2

I would like to propose a generalization with awk.

When the file is made by blocks of a fixed size and the lines to delete are repeated for each block, awk can work fine in such a way

awk '{nl=((NR-1)%2000)+1; if ( (nl<714) || ((nl>1025)&&(nl<1029)) ) print  $0}'
 OriginFile.dat > MyOutputCuttedFile.dat

In this example the size for the block is 2000 and I want to print the lines [1..713] and [1026..1029].

• NR is the variable used by awk to store the current line number.
• % gives the remainder (or modulus) of the division of two integers;
• nl=((NR-1)%BLOCKSIZE)+1 Here we write in the variable nl the line number inside the current block. (see below)
• || and && are the logical operator OR and AND.
• print $0 writes the full line

Why ((NR-1)%BLOCKSIZE)+1:
(NR-1) We need a shift of one because 1%3=1, 2%3=2, but 3%3=0.
  +1   We add again 1 because we want to restore the desired order.

+-----+------+----------+------------+
| NR  | NR%3 | (NR-1)%3 | (NR-1)%3+1 |
+-----+------+----------+------------+
|  1  |  1   |    0     |     1      |
|  2  |  2   |    1     |     2      |
|  3  |  0   |    2     |     3      |
|  4  |  1   |    0     |     1      |

When the compiler compiles the class User and gets to the MyMessageBox line, MyMessageBox has not yet been defined. The compiler has no idea MyMessageBox exists, so cannot understand the meaning of your class member.

You need to make sure MyMessageBox is defined before you use it as a member. This is solved by reversing the definition order. However, you have a cyclic dependency: if you move MyMessageBox above User, then in the definition of MyMessageBox the name User won't be defined!

What you can do is forward declare User; that is, declare it but don't define it. During compilation, a type that is declared but not defined is called an incomplete type. Consider the simpler example:

struct foo; // foo is *declared* to be a struct, but that struct is not yet defined

struct bar
{
    // this is okay, it's just a pointer;
    // we can point to something without knowing how that something is defined
    foo* fp; 

    // likewise, we can form a reference to it
    void some_func(foo& fr);

    // but this would be an error, as before, because it requires a definition
    /* foo fooMember; */
};

struct foo // okay, now define foo!
{
    int fooInt;
    double fooDouble;
};

void bar::some_func(foo& fr)
{
    // now that foo is defined, we can read that reference:
    fr.fooInt = 111605;
    fr.foDouble = 123.456;
}

By forward declaring User, MyMessageBox can still form a pointer or reference to it:

class User; // let the compiler know such a class will be defined

class MyMessageBox
{
public:
    // this is ok, no definitions needed yet for User (or Message)
    void sendMessage(Message *msg, User *recvr); 

    Message receiveMessage();
    vector<Message>* dataMessageList;
};

class User
{
public:
    // also ok, since it's now defined
    MyMessageBox dataMsgBox;
};

You cannot do this the other way around: as mentioned, a class member needs to have a definition. (The reason is that the compiler needs to know how much memory User takes up, and to know that it needs to know the size of its members.) If you were to say:

class MyMessageBox;

class User
{
public:
    // size not available! it's an incomplete type
    MyMessageBox dataMsgBox;
};

It wouldn't work, since it doesn't know the size yet.

On a side note, this function:

 void sendMessage(Message *msg, User *recvr);

Probably shouldn't take either of those by pointer. You can't send a message without a message, nor can you send a message without a user to send it to. And both of those situations are expressible by passing null as an argument to either parameter (null is a perfectly valid pointer value!)

Rather, use a reference (possibly const):

 void sendMessage(const Message& msg, User& recvr);

Per sys.hexversion and API and ABI Versioning:

import sys
if sys.hexversion >= 0x3000000:
    print('Python 3.x hexversion %s is in use.' % hex(sys.hexversion))

Short answer: you can't. Use MSIEXEC /x

Long answer: When you run the MSI file directly at the command line, all that's happening is that it runs MSIEXEC for you. This association is stored in the registry. You can see a list of associations by (in Windows Explorer) going to Tools / Folder Options / File Types.

For example, you can run a .DOC file from the command line, and WordPad or WinWord will open it for you.

If you look in the registry under HKEY_CLASSES_ROOT\.msi, you'll see that .MSI files are associated with the ProgID "Msi.Package". If you look in HKEY_CLASSES_ROOT\Msi.Package\shell\Open\command, you'll see the command line that Windows actually uses when you "run" a .MSI file.

Its very simple to send emails on localhost or local server

Note: I am using the test mail server software on Windows 7 64bit with Xampp installed

Just download test mail server tool and install according to the instruction given on its website Test Mail Server Tool

Now you need to change only two lines under php.ini file

1. Find [mail function] and remove semi colon which is before ;smtp = localhost
2. Put the semi colon before sendmail_path = "C:\xampp\mailtodisk\mailtodisk.exe"

You don't need to change anything else, but if you still not getting emails than check for the SMTP port, the port number must be same.

The above method is for default settings provided by the Xampp software.

You have it exactly right, all you have to do is set selectedIndex in your ng-click.

ng-click="selectedIndex = 1"

Here is how I implemented a set of buttons that change the ng-view, and highlights the button of the currently selected view.

<div id="sidebar" ng-init="partial = 'main'">
    <div class="routeBtn" ng-class="{selected:partial=='main'}" ng-click="router('main')"><span>Main</span></div>
    <div class="routeBtn" ng-class="{selected:partial=='view1'}" ng-click="router('view1')"><span>Resume</span></div>
    <div class="routeBtn" ng-class="{selected:partial=='view2'}" ng-click="router('view2')"><span>Code</span></div>
    <div class="routeBtn" ng-class="{selected:partial=='view3'}" ng-click="router('view3')"><span>Game</span></div>
  </div>

and this in my controller.

$scope.router = function(endpoint) {
    $location.path("/" + ($scope.partial = endpoint));
};

You can change the value of a static readonly string only in the static constructor of the class or a variable initializer, whereas you cannot change the value of a const string anywhere.
