Follow the following steps,

1. Update visual studio to latest version (it matters)
2. Remove all binding redirects from web.config

3. Add this to the .csproj file:

   <PropertyGroup>
     <AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>
     <GenerateBindingRedirectsOutputType>true</GenerateBindingRedirectsOutputType>
   </PropertyGroup>
   

4. Build the project
5. In the bin folder there should be a (WebAppName).dll.config file
6. It should have redirects in it, copy these to the web.config
7. Remove the above snipped from the .csproj file

It should work

I needed to do this from Jenkins pipeline, so, needed to upload files to specific folder name but not to the root container folder. I use --destination-path that can be folder or folder1/folder2

az storage blob upload-batch --account-name $AZURE_STORAGE_ACCOUNT --destination ${CONTAINER_NAME} --destination-path ${VERSION_FOLDER} --source ${BUILD_FOLDER} --account-key $ACCESS_KEY

hope this help to someone

1 Create login while connecting to the master db (in your databaseclient open a connection to the master db)

CREATE LOGIN 'testUserLogin' WITH password='1231!#ASDF!a';

2 Create a user while connecting to your db (in your db client open a connection to your database)

CREATE USER testUserLoginFROM LOGIN testUserLogin; Please, note, user name is the same as login. It did not work for me when I had a different username and login.

3 Add required permissions

EXEC sp_addrolemember db_datawriter, 'testUser'; You may want to add 'db_datareader' as well.

I was inspired by @nthpixel answer, but it did not work for my db client DBeaver. It did not allow me to run USE [master] and use [my-db] statements.

https://azure.microsoft.com/en-us/blog/adding-users-to-your-sql-azure-database/

How to test your user?

Run the query bellow in the master database connection.

SELECT A.name as userName, B.name as login, B.Type_desc, default_database_name, B.*
FROM sys.sysusers A
    FULL OUTER JOIN sys.sql_logins B
       ON A.sid = B.sid
WHERE islogin = 1 and A.sid is not null

List of all users in Azure SQL

Building on @tmullaney 's answer, you can also left join in the sys.objects view to get insight when explicit permissions have been granted on objects. Make sure to use the LEFT join:

SELECT DISTINCT pr.principal_id, pr.name AS [UserName], pr.type_desc AS [User_or_Role], pr.authentication_type_desc AS [Auth_Type], pe.state_desc,
    pe.permission_name, pe.class_desc, o.[name] AS 'Object' 
    FROM sys.database_principals AS pr 
    JOIN sys.database_permissions AS pe ON pe.grantee_principal_id = pr.principal_id
    LEFT JOIN sys.objects AS o on (o.object_id = pe.major_id)

If you are trying to install a module that is listed on the central repository for PS content called PowerShell Gallery, you need to install PowerShellGet. Then the command will be available. I'm currently using PS 4.0. Installing PowerShellGet did the trick for me.

Source:

With the latest PowerShellGet module, you can:

• Search through items in the Gallery with Find-Module and Find-Script
• Save items to your system from the Gallery with Save-Module and Save-Script
• Install items from the Gallery with Install-Module and Install-Script
• Upload items to the Gallery with Publish-Module and Publish-Script
• Add your own custom repository with Register-PSRepository

Another great article to get started with PS Gallery.

For Windows 10:

Right-click the taskbar Windows logo, select 'Programs and Features'.

Click 'Turn Windows Features on or off'

In the dialog box that appears, scroll down or resize the window and check the box next to 'Windows Identity Foundation 3.5'

Click OK.

This activates the required DLLs. Apparently Windows 10 keeps all of those features in the windows installation so that it can activate and deactivate them on demand.

I had the same problem in my Application.

System.web.http.webhost not found.

You just need to copy the system.web.http.webhost file from your main project which you run in Visual Studio and paste it into your published project bin directory.

After this it may show the same error but the directory name is changed it may be system.web.http. Follow same procedure as above. It will work after all the files are uploaded. This due to the nuget package in Visual Studio they download from the internet but on server it not able to download it.

You can find this file in your project bin directory.

Update: Ms SQL Server 2017+, Azure SQL Database

Well my old non-answer got rightfully deleted (left in-tact below), but if anyone happens to land here in the future, there is good news. They have implimented STRING_AGG() in Azure SQL Database as well. That should provide the exact functionality originally requested in this post with native and built in support. @hrobky mentioned this previously as a SQL Server 2016 feature at the time.

--- Old Post: Not enough reputation here to reply to @hrobky directly, but STRING_AGG looks great, however it is only available in SQL Server 2016 vNext currently. Hopefully it will follow to Azure SQL Datababse soon as well..

I think it is a lot easier now.

1. Launch SQL Management Studio
2. Right Click on "Databases" and select "Import Data-tier application..."
3. The wizard will take you through the process of connecting to your Azure account, creating a BACPAC file and creating your database.

Additionally, I use Sql Backup and FTP (https://sqlbackupandftp.com/) to do daily backups to a secure FTP server. I simply pull a recent BACPAC file from there and it import it in the same dialog, which is faster and easier to create a local database.

This issue can occur if the Azure Active Directory Module for Windows PowerShell isn't loaded correctly.

To resolve this issue, follow these steps.
1.Install the Azure Active Directory Module for Windows PowerShell on the computer (if it isn't already installed). To install the Azure Active Directory Module for Windows PowerShell, go to the following Microsoft website:
Manage Azure AD using Windows PowerShell

2.If the MSOnline module isn't present, use Windows PowerShell to import the MSOnline module.

Import-Module MSOnline 

After it complete, we can use this command to check it.

PS C:\Users> Get-Module -ListAvailable -Name MSOnline*

We should import azure AD powershell to VS 2015, we can add tool and select Azure AD powershell.

From this document, this DTU percent is determined by this query:

SELECT end_time,   
  (SELECT Max(v)    
   FROM (VALUES (avg_cpu_percent), (avg_data_io_percent), 
(avg_log_write_percent)) AS    
   value(v)) AS [avg_DTU_percent]   
FROM sys.dm_db_resource_stats;  

looks like the max of avg_cpu_percent, avg_data_io_percent and avg_log_write_percent

I would like to add that Lin's answer is correct.

If you improperly delete the MDF you will have to fix it. To fix the screwed up connections in the project to the MDF. Short answer; recreate and delete it properly.

1. Create a new MDF and name it the same as the old MDF, put it in the same folder location. You can create a new project and create a new mdf. The mdf does not have to match your old tables, because were going to delete it. So create or copy an old one to the correct folder.
2. Open it in server explorer [double click the mdf from solution explorer]
3. Delete it in server explorer
4. Delete it from solution explorer
5. run update-database -force [Use force if necessary]

Done, enjoy your new db

UPDATE 11/12/14 - I use this all the time when I make a breaking db change. I found this is a great way to roll back your migrations to the original db:

• Puts the db back to original

• Run the normal migration to put it back to current

  1. Update-Database -TargetMigration:0 -force [This will destroy all tables and all data.]
  2. Update-Database -force [use force if necessary]

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.

I too struggled with something similar. My guess is your actual problem is connecting to a SQL Express instance running on a different machine. The steps to do this can be summarized as follows:

1. Ensure SQL Express is configured for SQL Authentication as well as Windows Authentication (the default). You do this via SQL Server Management Studio (SSMS) Server Properties/Security
2. In SSMS create a new login called "sqlUser", say, with a suitable password, "sql", say. Ensure this new login is set for SQL Authentication, not Windows Authentication. SSMS Server Security/Logins/Properties/General. Also ensure "Enforce password policy" is unchecked
3. Under Properties/Server Roles ensure this new user has the "sysadmin" role
4. In SQL Server Configuration Manager SSCM (search for SQLServerManagerxx.msc file in Windows\SysWOW64 if you can't find SSCM) under SQL Server Network Configuration/Protocols for SQLExpress make sure TCP/IP is enabled. You can disable Named Pipes if you want
5. Right-click protocol TCP/IP and on the IPAddresses tab, ensure every one of the IP addresses is set to Enabled Yes, and TCP Port 1433 (this is the default port for SQL Server)
6. In Windows Firewall (WF.msc) create two new Inbound Rules - one for SQL Server and another for SQL Browser Service. For SQL Server you need to open TCP Port 1433 (if you are using the default port for SQL Server) and very importantly for the SQL Browser Service you need to open UDP Port 1434. Name these two rules suitably in your firewall
7. Stop and restart the SQL Server Service using either SSCM or the Services.msc snap-in
8. In the Services.msc snap-in make sure SQL Browser Service Startup Type is Automatic and then start this service

At this point you should be able to connect remotely, using SQL Authentication, user "sqlUser" password "sql" to the SQL Express instance configured as above. A final tip and easy way to check this out is to create an empty text file with the .UDL extension, say "Test.UDL" on your desktop. Double-clicking to edit this file invokes the Microsoft Data Link Properties dialog with which you can quickly test your remote SQL connection

A nice way to achieve this "if you have an office 365 account" is to use Office 365 outlook connector integrated with Azure Logic App,

Hope this helps someone!

If all you need is to ensure uniqueness of elements, then HashSet is what you need.

What do you mean when you say "just a set implementation"? A set is (by definition) a collection of unique elements that doesn't save element order.

find . -size +10000k -exec ls -sd {} +

If your version of find won't accept the + notation (which acts rather like xargs does), then you might use (GNU find and xargs, so find probably supports + anyway):

find . -size +10000k -print0 | xargs -0 ls -sd

or you might replace the + with \; (and live with the relative inefficiency of this), or you might live with problems caused by spaces in names and use the portable:

find . -size +10000k -print | xargs ls -sd

The -d on the ls commands ensures that if a directory is ever found (unlikely, but...), then the directory information will be printed, not the files in the directory. And, if you're looking for files more than 1 MB (as a now-deleted comment suggested), you need to adjust the +10000k to 1000k or maybe +1024k, or +2048 (for 512-byte blocks, the default unit for -size). This will list the size and then the file name. You could avoid the need for -d by adding -type f to the find command, of course.

Importing a whole library seems inefficient when all you need is essentially two lines of code...

$ldap = ldap_connect("ldap.example.com");
if ($bind = ldap_bind($ldap, $_POST['username'], $_POST['password'])) {
  // log them in!
} else {
  // error message
}

The IEEE standard says when the exponent is all 1s and the mantissa is not zero, the number is a NaN. Double is 1 sign bit, 11 exponent bits and 52 mantissa bits. Do a bit check.

If your compiler is GCC you can also use following syntax:

int array[256] = {[0 ... 255] = 0};

Please look at http://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/Designated-Inits.html#Designated-Inits, and note that this is a compiler-specific feature.

A late answer, although I figured out a solution which could help others:

Java version

Intent emailIntent = new Intent(Intent.ACTION_SENDTO);
emailIntent.setData(Uri.parse("mailto:[email protected]"));
startActivity(Intent.createChooser(emailIntent, "Send feedback"));

Kotlin version

val emailIntent = Intent(Intent.ACTION_SENDTO).apply { 
    data = Uri.parse("mailto:[email protected]")
}
startActivity(Intent.createChooser(emailIntent, "Send feedback"))

This was my output (only Gmail + Inbox suggested):

I got this solution from the Android Developers site.

A String is a type of Object. So any method that accepts Object as parameter will surely accept String also. Please provide more of your code if you still do not find a solution.

Definitely using the Url property is the way to go. Whether to set it in the app.config, the database, or a third location sort of depends on your configuration needs. Sometimes you don't want the app to restart when you change the web service location. You might not have a load balancer scaling the backend. You might be hot-patching a web service bug. Your implementation might have security configuration issues as well. Whether it's production db usernames and passwords or even the ws security auth info. The proper separation of duties can get you into some more involved configuration setups.

If you add a wrapper class around the proxy generated classes, you can set the Url property in some unified fashion every time you create the wrapper class to call a web method.

This is most probably caused by a missing or incomplete PATH environment variable.

If you provide full absolute paths to your executables (su and node) it will work.

Looks like java version conflicts.

Please refer https://medium.com/lucian-daniliuc/upgrading-jenkins-on-ubuntu-14-04-lts-df3e1209f98c

var myText = 'GOOGLE';

$('#HowYouKnow option').map(function() {
    if ($(this).text() == myText) return this;
}).attr('selected', 'selected');

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
           header=TRUE, skip=3)

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

> From what I've heard ...

Your difficulty seems to be in deciding whether what you have heard is credible, and that difficulty will just be repeated when you try to assess the replies on this site.

How are you going to decide if the things people say here are more or less credible than what you originally heard?

One way would be to ask for evidence.

When someone claims "there are some areas in which C# proves to be faster than C++" ask them why they say that, ask them to show you measurements, ask them to show you programs. Sometimes they will simply have made a mistake. Sometimes you'll find out that they are just expressing an opinion rather than sharing something that they can show to be true.

Often information and opinion will be mixed up in what people claim, and you'll have to try and sort out which is which. For example, from the replies in this forum:

• "Take the benchmarks at http://shootout.alioth.debian.org/ with a great deal of scepticism, as these largely test arithmetic code, which is most likely not similar to your code at all."

  Ask yourself if you really understand what "these largely test arithmetic code" means, and then ask yourself if the author has actually shown you that his claim is true.

• "That's a rather useless test, since it really depends on how well the individual programs have been optimized; I've managed to speed up some of them by 4-6 times or more, making it clear that the comparison between unoptimized programs is rather silly."

  Ask yourself whether the author has actually shown you that he's managed to "speed up some of them by 4-6 times or more" - it's an easy claim to make!

Set the CSS position: relative; on the box. This causes all absolute positions of objects inside to be relative to the corners of that box. Then set the following CSS on the "Bet 5 days ago" line:

position: absolute;
bottom: 0;
right: 0;

If you need to space the text farther away from the edge, you could change 0 to 2px or similar.

If your string is in ISO 8601 format, you can also use from_iso8601_timestamp

String.prototype.startsWith = function(needle)
{
    return this.indexOf(needle) === 0;
};

This is not a direct answer to your question (which was answered pretty well already). However, having had times bite me on the fundament several times, I cannot stress enough that it would behoove you to look closely at what your time.struct_time object is providing, vs. what other time fields may have.

Assuming you have both a time.struct_time object, and some other date/time string, compare the two, and be sure you are not losing data and inadvertently creating a naive datetime object, when you can do otherwise.

For example, the excellent feedparser module will return a "published" field and may return a time.struct_time object in its "published_parsed" field:

time.struct_time(tm_year=2013, tm_mon=9, tm_mday=9, tm_hour=23, tm_min=57, tm_sec=42, tm_wday=0, tm_yday=252, tm_isdst=0)

Now note what you actually get with the "published" field.

Mon, 09 Sep 2013 19:57:42 -0400

By Stallman's Beard! Timezone information!

In this case, the lazy man might want to use the excellent dateutil module to keep the timezone information:

from dateutil import parser
dt = parser.parse(entry["published"])
print "published", entry["published"])
print "dt", dt
print "utcoffset", dt.utcoffset()
print "tzinfo", dt.tzinfo
print "dst", dt.dst()

which gives us:

published Mon, 09 Sep 2013 19:57:42 -0400
dt 2013-09-09 19:57:42-04:00
utcoffset -1 day, 20:00:00
tzinfo tzoffset(None, -14400)
dst 0:00:00

One could then use the timezone-aware datetime object to normalize all time to UTC or whatever you think is awesome.

Since maps v2 is deprecated, you are probably interested in v3 maps: https://developers.google.com/maps/documentation/javascript/markers#simple_icons

For v2 maps:

http://code.google.com/apis/maps/documentation/overlays.html#Icons_overview

You would have one set of logic do all the 'regular' pins, and another that does the 'special' pin(s) using the new marker defined.

Generally it is a versioning issue. Node.js v8 cannot compile with angular-cli 6.0 or later. angularcli v6 and above will work for lastest node versions. Please make sure if your node version is v8, then you need to install angular-cli upto 1.7.4. enter ng -v command in cmd and check the cli and node versions.

Try the following code:

void clean(char *var) {
    int i = 0;
    while(var[i] != '\0') {
        var[i] = '\0';
        i++;
    }
}

so if you need want use this code )

import { useRoutes } from "./routes";

import { BrowserRouter as Router } from "react-router-dom";

export const App = () => {

const routes = useRoutes(true);

  return (

    <Router>

      <div className="container">{routes}</div>

    </Router>

  );

};

// ./routes.js 

import { Switch, Route, Redirect } from "react-router-dom";

export const useRoutes = (isAuthenticated) => {
  if (isAuthenticated) {
    return (
      <Switch>
        <Route path="/links" exact>
          <LinksPage />
        </Route>
        <Route path="/create" exact>
          <CreatePage />
        </Route>
        <Route path="/detail/:id">
          <DetailPage />
        </Route>
        <Redirect path="/create" />
      </Switch>
    );
  }
  return (
    <Switch>
      <Route path={"/"} exact>
        <AuthPage />
      </Route>
      <Redirect path={"/"} />
    </Switch>
  );
};

You need to set this permission in your manifest.xml file

android.permission.WRITE_EXTERNAL_STORAGE

You could try this approach:

1. Get the current date.

2. Add the the number of years which is equal to the difference between the current date's year and the specified year.

3. Subtract the number of days that is the last obtained date's week day's number (and it will give us the last day of some week).

4. Add the number of weeks which is the difference between the last obtained date's week number and the specified week number, and that will yield the last day of the desired week.

5. Subtract 6 days to obtain the first day.

Some years ago, in a safety critical field, I have heard something like one day for unit testing ten lines of code.

I have also observed 50% of effort for development and 50% for testing (not only unit testing).

Used

String[] words = {"{apf","hum_","dkoe","12f"};
    for(String s:words)
    {
        if(s.matches("[a-z]+"))
        {
            System.out.println(s);
        }
    }

Insert "checkbox". Every time you check or uncheck the box the sheet recalculates. If you put the text size for the checkbox at 2, the color at almost black and the cell shade to black, it becomes a button that recalculates.

For Chrome on macOS, if you don't want to delete the entire Chrome favicon database as suggested already here, you can delete only the conflicting icons:

1. Quit Chrome
2. Load the favicons database (using sqlite here):

sqlite3 ~/Library/Application\ Support/Google/Chrome/Default/Favicons

3. Search for the file that is causing issues

select * from favicons where url = 'http://mysite.dev/favicon.ico';

4. If you are happy with the output:

delete from favicons where url = 'http://mysite.dev/favicon.ico';

Alternatively, you can search for a pattern that you can reuse to delete multiple entries:

3. Search for multiple files that are causing issues

select * from favicons where url like 'http://mysite.dev%';

4. And again if you are happy with what this returns:

delete from favicons where url like 'http://mysite.dev%';

5. Type .exit and hit return to quit sqlite
6. Restart Chrome

Use wp_localize_script and pass url there:

wp_localize_script( some_handle, 'admin_url', array('ajax_url' => admin_url( 'admin-ajax.php' ) ) );

then inside js, you can call it by

admin_url.ajax_url 

If you are on Windows, you can go to:

C:\Users\{your_name}\.gradle

And delete all the references of the gradle package you can find in those folders:

1. caches
2. daemon
3. wrapper

Then re-open your project and sync gradle

Maybe this is not the best way, but it works.

String pl = Page.Request.PhysicalPath;

// Replace the backslash with slash in your path    
pl = pl.Replace("\\", "/");    
p = p.Replace("\\", "/");

// Root path     
String rp = pl.Replace(pn, "");

// Take out same path    
String final = p.Replace(rp, "");

// So your picture's address is    
String path = sa + final;

Edit: Ok, somebody marked as not helpful. Some explanation: take the physical path of the current page, split it into two parts: server and directory (like c:\inetpub\whatever.com\whatever) and page name (like /Whatever.aspx). The image's physical path should contain the server's path, so "substract" them, leaving only the image's path relative to the server's (like: \design\picture.jpg). Replace the backslashes with slashes and append it to the server's url.

You want the NPGSQL library. Your only other alternative is ODBC.

Use TO_TIMESTAMP function

TO_TIMESTAMP(date_string,'YYYY-MM-DD HH24:MI:SS')

SELECT column_name,data_type 
FROM information_schema.columns 
WHERE
table_name = 'your_table_name' 
AND table_catalog = 'your_database_name' 
AND table_schema = 'your_schema_name';

The Wikipedia newline article might help you out. Here is an excerpt:

The different newline conventions often cause text files that have been transferred between systems of different types to be displayed incorrectly. For example, files originating on Unix or Apple Macintosh systems may appear as a single long line on some programs running on Microsoft Windows. Conversely, when viewing a file originating from a Windows computer on a Unix system, the extra CR may be displayed as ^M or at the end of each line or as a second line break.

I really like this method as well, less clutter:

count=$[count+1]

The approach I suggest is a bit verbose but I found it to scale pretty well into complex apps. When you want to show a modal, fire an action describing which modal you'd like to see:

Dispatching an Action to Show the Modal

this.props.dispatch({
  type: 'SHOW_MODAL',
  modalType: 'DELETE_POST',
  modalProps: {
    postId: 42
  }
})

(Strings can be constants of course; I’m using inline strings for simplicity.)

Writing a Reducer to Manage Modal State

Then make sure you have a reducer that just accepts these values:

const initialState = {
  modalType: null,
  modalProps: {}
}

function modal(state = initialState, action) {
  switch (action.type) {
    case 'SHOW_MODAL':
      return {
        modalType: action.modalType,
        modalProps: action.modalProps
      }
    case 'HIDE_MODAL':
      return initialState
    default:
      return state
  }
}

/* .... */

const rootReducer = combineReducers({
  modal,
  /* other reducers */
})

Great! Now, when you dispatch an action, state.modal will update to include the information about the currently visible modal window.

Writing the Root Modal Component

At the root of your component hierarchy, add a <ModalRoot> component that is connected to the Redux store. It will listen to state.modal and display an appropriate modal component, forwarding the props from the state.modal.modalProps.

// These are regular React components we will write soon
import DeletePostModal from './DeletePostModal'
import ConfirmLogoutModal from './ConfirmLogoutModal'

const MODAL_COMPONENTS = {
  'DELETE_POST': DeletePostModal,
  'CONFIRM_LOGOUT': ConfirmLogoutModal,
  /* other modals */
}

const ModalRoot = ({ modalType, modalProps }) => {
  if (!modalType) {
    return <span /> // after React v15 you can return null here
  }

  const SpecificModal = MODAL_COMPONENTS[modalType]
  return <SpecificModal {...modalProps} />
}

export default connect(
  state => state.modal
)(ModalRoot)

What have we done here? ModalRoot reads the current modalType and modalProps from state.modal to which it is connected, and renders a corresponding component such as DeletePostModal or ConfirmLogoutModal. Every modal is a component!

Writing Specific Modal Components

There are no general rules here. They are just React components that can dispatch actions, read something from the store state, and just happen to be modals.

For example, DeletePostModal might look like:

import { deletePost, hideModal } from '../actions'

const DeletePostModal = ({ post, dispatch }) => (
  <div>
    <p>Delete post {post.name}?</p>
    <button onClick={() => {
      dispatch(deletePost(post.id)).then(() => {
        dispatch(hideModal())
      })
    }}>
      Yes
    </button>
    <button onClick={() => dispatch(hideModal())}>
      Nope
    </button>
  </div>
)

export default connect(
  (state, ownProps) => ({
    post: state.postsById[ownProps.postId]
  })
)(DeletePostModal)

The DeletePostModal is connected to the store so it can display the post title and works like any connected component: it can dispatch actions, including hideModal when it is necessary to hide itself.

Extracting a Presentational Component

It would be awkward to copy-paste the same layout logic for every “specific” modal. But you have components, right? So you can extract a presentational <Modal> component that doesn’t know what particular modals do, but handles how they look.

Then, specific modals such as DeletePostModal can use it for rendering:

import { deletePost, hideModal } from '../actions'
import Modal from './Modal'

const DeletePostModal = ({ post, dispatch }) => (
  <Modal
    dangerText={`Delete post ${post.name}?`}
    onDangerClick={() =>
      dispatch(deletePost(post.id)).then(() => {
        dispatch(hideModal())
      })
    })
  />
)

export default connect(
  (state, ownProps) => ({
    post: state.postsById[ownProps.postId]
  })
)(DeletePostModal)

It is up to you to come up with a set of props that <Modal> can accept in your application but I would imagine that you might have several kinds of modals (e.g. info modal, confirmation modal, etc), and several styles for them.

Accessibility and Hiding on Click Outside or Escape Key

The last important part about modals is that generally we want to hide them when the user clicks outside or presses Escape.

Instead of giving you advice on implementing this, I suggest that you just don’t implement it yourself. It is hard to get right considering accessibility.

Instead, I would suggest you to use an accessible off-the-shelf modal component such as react-modal. It is completely customizable, you can put anything you want inside of it, but it handles accessibility correctly so that blind people can still use your modal.

You can even wrap react-modal in your own <Modal> that accepts props specific to your applications and generates child buttons or other content. It’s all just components!

Other Approaches

There is more than one way to do it.

Some people don’t like the verbosity of this approach and prefer to have a <Modal> component that they can render right inside their components with a technique called “portals”. Portals let you render a component inside yours while actually it will render at a predetermined place in the DOM, which is very convenient for modals.

In fact react-modal I linked to earlier already does that internally so technically you don’t even need to render it from the top. I still find it nice to decouple the modal I want to show from the component showing it, but you can also use react-modal directly from your components, and skip most of what I wrote above.

I encourage you to consider both approaches, experiment with them, and pick what you find works best for your app and for your team.

You can change your target's launch settings in "Manage Scheme" to Wait for <app>.app to be launched manually, which allows you debug by setting a breakpoint in application: didReceiveRemoteNotification: fetchCompletionHandler: and sending the push notification to trigger the background launch.

I'm not sure it'll solve the issue, but it may assist you with debugging for now.

I just wanted to echo @Luann's comment as I use this approach always.

Just right click on the table > Script table as > Select to > New Query window.

You will see the select query. Just take out the column you want to exclude and you have your preferred select query.

Here's a relatively easy method to do this. Throw a GridView into your layout, setting the stretch mode to stretch the column widths, set the spacing to 0 (or whatever you want), and set the number of columns to 2:

res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <GridView
        android:id="@+id/gridview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:verticalSpacing="0dp"
        android:horizontalSpacing="0dp"
        android:stretchMode="columnWidth"
        android:numColumns="2"/>

</FrameLayout>

Make a custom ImageView that maintains its aspect ratio:

src/com/example/graphicstest/SquareImageView.java

public class SquareImageView extends ImageView {
    public SquareImageView(Context context) {
        super(context);
    }

    public SquareImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public SquareImageView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        setMeasuredDimension(getMeasuredWidth(), getMeasuredWidth()); //Snap to width
    }
}

Make a layout for a grid item using this SquareImageView and set the scaleType to centerCrop:

res/layout/grid_item.xml

<?xml version="1.0" encoding="utf-8"?>

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
             android:layout_width="match_parent"
             android:layout_height="match_parent">

    <com.example.graphicstest.SquareImageView
        android:id="@+id/picture"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop"/>

    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:paddingTop="15dp"
        android:paddingBottom="15dp"
        android:layout_gravity="bottom"
        android:textColor="@android:color/white"
        android:background="#55000000"/>

</FrameLayout>

Now make some sort of adapter for your GridView:

src/com/example/graphicstest/MyAdapter.java

private final class MyAdapter extends BaseAdapter {
    private final List<Item> mItems = new ArrayList<Item>();
    private final LayoutInflater mInflater;

    public MyAdapter(Context context) {
        mInflater = LayoutInflater.from(context);

        mItems.add(new Item("Red",       R.drawable.red));
        mItems.add(new Item("Magenta",   R.drawable.magenta));
        mItems.add(new Item("Dark Gray", R.drawable.dark_gray));
        mItems.add(new Item("Gray",      R.drawable.gray));
        mItems.add(new Item("Green",     R.drawable.green));
        mItems.add(new Item("Cyan",      R.drawable.cyan));
    }

    @Override
    public int getCount() {
        return mItems.size();
    }

    @Override
    public Item getItem(int i) {
        return mItems.get(i);
    }

    @Override
    public long getItemId(int i) {
        return mItems.get(i).drawableId;
    }

    @Override
    public View getView(int i, View view, ViewGroup viewGroup) {
        View v = view;
        ImageView picture;
        TextView name;

        if (v == null) {
            v = mInflater.inflate(R.layout.grid_item, viewGroup, false);
            v.setTag(R.id.picture, v.findViewById(R.id.picture));
            v.setTag(R.id.text, v.findViewById(R.id.text));
        }

        picture = (ImageView) v.getTag(R.id.picture);
        name = (TextView) v.getTag(R.id.text);

        Item item = getItem(i);

        picture.setImageResource(item.drawableId);
        name.setText(item.name);

        return v;
    }

    private static class Item {
        public final String name;
        public final int drawableId;

        Item(String name, int drawableId) {
            this.name = name;
            this.drawableId = drawableId;
        }
    }
}

Set that adapter to your GridView:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    GridView gridView = (GridView)findViewById(R.id.gridview);
    gridView.setAdapter(new MyAdapter(this));
}

And enjoy the results:

Don't use "Style:

worksheet.Cells[y,x].HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignLeft;

The existing answers are now outdated. The native getBoundingClientRect() method has been around for quite a while now, and does exactly what the question asks for. Plus it is supported across all browsers (including IE 5, it seems!)

From MDN page:

The returned value is a TextRectangle object, which contains read-only left, top, right and bottom properties describing the border-box, in pixels, with the top-left relative to the top-left of the viewport.

You use it like so:

var viewportOffset = el.getBoundingClientRect();
// these are relative to the viewport, i.e. the window
var top = viewportOffset.top;
var left = viewportOffset.left;

I also had an issue with multiline strings in this scenario. @Iman's backtick(`) solution worked great in the modern browsers but caused an invalid character error in Internet Explorer. I had to use the following:

'@item.MultiLineString.Replace(Environment.NewLine, "<br />")'

Then I had to put the carriage returns back again in the js function. Had to use RegEx to handle multiple carriage returns.

// This will work for the following:
// "hello\nworld"
// "hello<br>world"
// "hello<br />world"
$("#MyTextArea").val(multiLineString.replace(/\n|<br\s*\/?>/gi, "\r"));

Same problem with me. I solved this by adding @ before connection string (C# has a thing called 'String Literals') like so:

SqlConnection sconnection = new SqlConnection(@"Data Source=(Localdb)\v11.0; Initial Catalog=Mydatabase;Integrated Security=True");

sconnection.Open();

When Spring loads your bean definitions, and has been configured to look for @Transactional annotations, it will create these proxy objects around your actual bean. These proxy objects are instances of classes that are auto-generated at runtime. The default behaviour of these proxy objects when a method is invoked is just to invoke the same method on the "target" bean (i.e. your bean).

However, the proxies can also be supplied with interceptors, and when present these interceptors will be invoked by the proxy before it invokes your target bean's method. For target beans annotated with @Transactional, Spring will create a TransactionInterceptor, and pass it to the generated proxy object. So when you call the method from client code, you're calling the method on the proxy object, which first invokes the TransactionInterceptor (which begins a transaction), which in turn invokes the method on your target bean. When the invocation finishes, the TransactionInterceptor commits/rolls back the transaction. It's transparent to the client code.

As for the "external method" thing, if your bean invokes one of its own methods, then it will not be doing so via the proxy. Remember, Spring wraps your bean in the proxy, your bean has no knowledge of it. Only calls from "outside" your bean go through the proxy.

Does that help?

Use the command line utility TF - Team Foundation Version Control Tool (tf).

You can get a list of all workspaces by bringing up a Visual Studio Command Prompt then changing to your workspace folder and issuing the following commands:

C:\YourWorkspaceFolder>tf workspaces /owner:*

You should see your problem workspace in the list as well as it's owner.

You can delete the workspace with the following command:

C:\YourWorkspaceFolder>tf workspace /delete /server:BUILDSERVER WORKSPACENAME;OWNERNAME

State machines can be very complex for a complex problem. They are also subject to unexpected bugs. They can turn into a nightmare if someone runs into a bug or needs to change the logic in the future. They are also difficult to follow and debug without the state diagram. Structured programming is much better (for example you would probably not use a state machine at mainline level). You can use structured programming even in interrupt context (which is where state machines are usually used). See this article "Macros to simulate multi-tasking/blocking code at interrupt level" found at codeproject.com.

In Symfony you can use this for protocol and host:

{{ app.request.schemeAndHttpHost }}

Though @alessandro1997 gave a perfect answer about concatenation.

In python 3.x all strings are sequences of Unicode characters. and doing the isinstance check for str (which means unicode string by default) should suffice.

isinstance(x, str)

With regards to python 2.x, Most people seem to be using an if statement that has two checks. one for str and one for unicode.

If you want to check if you have a 'string-like' object all with one statement though, you can do the following:

isinstance(x, basestring)

You can use the CSS property page-break-before (or page-break-after). Just set page-break-before: always on those block-level elements (e.g., heading, div, p, or table elements) that should start on a new line.

For example, to cause a line break before any 2nd level heading and before any element in class newpage (e.g., <div class=newpage>...), you would use

h2, .newpage { page-break-before: always }

In addition to the answer of Dyppl, I think it would be nice to place this inside the OnDataContextChanged event:

private void OnDataContextChanged(object sender, DependencyPropertyChangedEventArgs e)
{
    // Unforunately we cannot bind from the viewmodel to the code behind so easily, the dependency property is not available in XAML. (for some reason).
    // To work around this, we create the binding once we get the viewmodel through the datacontext.
    var newViewModel = e.NewValue as MyViewModel;

    var executablePathBinding = new Binding
    {
        Source = newViewModel,
        Path = new PropertyPath(nameof(newViewModel.ExecutablePath))
    };

    BindingOperations.SetBinding(LayoutRoot, ExecutablePathProperty, executablePathBinding);
}

We have also had cases were we just saved the DataContext to a local property and used that to access viewmodel properties. The choice is of course yours, I like this approach because it is more consistent with the rest. You can also add some validation, like null checks. If you actually change your DataContext around, I think it would be nice to also call:

BindingOperations.ClearBinding(myText, TextBlock.TextProperty);

to clear the binding of the old viewmodel (e.oldValue in the event handler).

Here is a super simple solution to show the concept of elegance. It's basically for grid snaps.

(pseudo code)

nearestPos = Math.Ceil( numberToRound / multiple ) * multiple;

too many ) parenthesis remove one of them.

There is a much easier way than everything above and this approach does not require the use of android.permission.GET_TASKS in the manifest, or have the issue of race conditions or memory leaks pointed out in the accepted answer.

1. Make a STATIC variable in the main Activity. Static allows other activities to receive the data from another activity. onPause() set this variable false, onResume and onCreate() set this variable true.

   private static boolean mainActivityIsOpen;
   

2. Assign getters and setters of this variable.

   public static boolean mainActivityIsOpen() {
       return mainActivityIsOpen;
   }
   
   public static void mainActivityIsOpen(boolean mainActivityIsOpen) {
       DayView.mainActivityIsOpen = mainActivityIsOpen;
   }
   

3. And then from another activity or Service

   if (MainActivity.mainActivityIsOpen() == false)
   {
                   //do something
   }
   else if(MainActivity.mainActivityIsOpen() == true)
   {//or just else. . . ( or else if, does't matter)
           //do something
   }
   

 protected void Page_Init(object sender, EventArgs e)
 {
   String hostdet = Request.ServerVariables["HTTP_HOST"].ToString();
 }

If you want to fire the event only on changes of your input use:

$('.s').bind('input', function(){
  console.log("search!");
  doSearch();
});

Here is a proposal of an URL parser regex that recognizes :

• Protocol
• Host
• Port
• Path (Document/folder)
• Get parameters

^(?>(?<protocol>[[:alpha:]]+(?>\:[[:alpha:]]+)*)\:\/\/)?(?<host>(?>[[:alnum:]]|[-_.])+)(?>\:(?<port>[[:digit:]]+))?(?<path>\/(?>[[:alnum:]]|[-_.\/])*)?(?>\?(?<request>(?>[[:alnum:]]+=[[:alnum:]]+)(?>\&(?>[[:alnum:]]+=[[:alnum:]]+))*))?$

This regex is able to parse an URL such :

jdbc:hsqldb:hsql://localhost:91/index.

There can be many way to engineer a URL regex, thus the one I propose can be lightly adapted to match more accurate URL grammars.

It can be tested on the following page : https://regex101.com/r/Dy7HE0/5

Be aware that langages native API for regex (such as java.util.regex) don't support smart character classes such as [[:alnum:]] and [[:alpha:]].

Use instead \w and \d.

Since android doesnt support <ol>, <ul> or <li> html elements, I had to do it like this

<string name="names"><![CDATA[<p><h2>List of Names:</h2></p><p>&#8226;name1<br />&#8226;name2<br /></p>]]></string>

if you want to maintain custom space then use </pre> tag

I have had the same problem in my project. I used an IntelliJ Idea 14 and Maven 8. And what I've noticed is that when I added a tomcat destination to to IDE it automaticly linked two jars from tomcat lib directory, they were servlet-api and jsp-api. Also I had them in my pom.xml. I killed a whole day trying to figure out why I'm getting java.lang.ClassNotFoundException: org.apache.jsp.index_jsp. And kewpiedoll99 is right. That is because there are dependency conflicts. When I added provided to those two jars in my pom.xml I found a happiness :)

Using recursion combined with the square root rule from here, checks whether a number is prime or not:

function isPrime(num){

    // An integer is prime if it is not divisible by any prime less than or equal to its square root
    var squareRoot = parseInt(Math.sqrt(num));
    var primeCountUp = function(divisor){
        if(divisor > squareRoot) {
            // got to a point where the divisor is greater than 
            // the square root, therefore it is prime
            return true;
        }
        else if(num % divisor === 0) {
            // found a result that divides evenly, NOT prime
            return false;
        }
        else {
            // keep counting
            return primeCountUp(++divisor);
        }
    };

    // start @ 2 because everything is divisible by 1
    return primeCountUp(2);

}

Also you can use ng-repeat with ng-if:

<div ng-repeat="(key, value) in order" ng-if="value > 0">

Usually, an Alpine Linux image doesn't contain bash, Instead you can use /bin/ash, /bin/sh, ash or only sh.

/bin/ash

docker run -it --rm alpine /bin/ash

/bin/sh

docker run -it --rm alpine /bin/sh

ash

docker run -it --rm alpine ash

sh

docker run -it --rm alpine sh

I hope this information helps you.

This solution will work for all cases even if there are multiple rows or any number of elements. But the count of the section should be same you want 4 in first row and 3 is second row it won't work that way the space for the 4th content will be blank the container won't fill.

We are using display: grid; and its properties.

#box {_x000D_
  display: grid;_x000D_
  width: 100px;_x000D_
  grid-gap: 5px;_x000D_
  /* Space between items */_x000D_
  grid-template-columns: 1fr 1fr 1fr 1fr;_x000D_
  /* Decide the number of columns and size */_x000D_
}_x000D_
_x000D_
.item {_x000D_
  background: gray;_x000D_
  width: 100%;_x000D_
  /* width is not necessary only added this to understand that width works as 100% to the grid template allocated space **DEFAULT WIDTH WILL BE 100%** */_x000D_
  height: 50px;_x000D_
}

<div id='box'>_x000D_
  <div class='item'></div>_x000D_
  <div class='item'></div>_x000D_
  <div class='item'></div>_x000D_
  <div class='item'></div>_x000D_
  <div class='item'></div>_x000D_
  <div class='item'></div>_x000D_
  <div class='item'></div>_x000D_
  <div class='item'></div>_x000D_
</div>

The Downside of this method is in Mobile Opera Mini will not be supported and in PC this works only after IE10.

Note for complete browser compatability including IE11 please use Autoprefixer

OLD ANSWER

Don't think of it as an old solution, it's still one of the best if you only want single row of elements and it will work with all the browsers.

This method is used by CSS sibling combination, so you can manipulate it many other ways also, but if your combination is wrong it may cause issues also.

.item+.item{
  margin-left: 5px;
}

The below code will do the trick. In this method, there is no need to give margin: 0 -5px; to the #box wrapper.

A working sample for you:

#box {_x000D_
  display: flex;_x000D_
  width: 100px;_x000D_
}_x000D_
.item {_x000D_
  background: gray;_x000D_
  width: 22px;_x000D_
  height: 50px;_x000D_
}_x000D_
.item+.item{_x000D_
 margin-left: 5px;_x000D_
}

<div id='box'>_x000D_
  <div class='item'></div>_x000D_
  <div class='item'></div>_x000D_
  <div class='item'></div>_x000D_
  <div class='item'></div>_x000D_
</div>

From the Java API:

Document result = mongoDatabase.runCommand(new Document("buildInfo", 1));
String version = (String) result.get("version");
List<Integer> versionArray = (List<Integer>) result.get("versionArray");

It doesn't work on Ubuntu 16.04, it seems that some libraries have been forgotten in the python installation package on this one. You should use package manager instead.

Solution

Uninstall matplotlib from pip then install it again with apt-get

python 2:

sudo pip uninstall matplotlib
sudo apt-get install python-matplotlib

python 3:

sudo pip3 uninstall matplotlib
sudo apt-get install python3-matplotlib

wget -O yourfilename.zip remote-storage.url/theirfilename.zip

will do the trick for you.

Note:

a) its a capital O.

b) wget -O filename url will only work. Putting -O last will not.

is null is the syntax I use for such things, when COALESCE is of no help.

Try:

if (@zipCode is null)
  begin
    ([Portal].[dbo].[Address].Position.Filter(@radiusBuff) = 1)   
  end
else 
  begin
    ([Portal].[dbo].[Address].PostalCode=@zipCode )
  end  

You'll find that instances of list do not provide a __hash__ --rather, that attribute of each list is actually None (try print [].__hash__). Thus, list is unhashable.

The reason your code works with list and not set is because set constructs a single set of items without duplicates, whereas a list can contain arbitrary data.

I thought I would provide a much more robust example, also in typescript, but it would be easy to convert to pure javascript. This function will query parents using either the ID like so "#my-element" or the class ".my-class" and unlike some of these answers will handle multiple classes. I found I named some similarly and so the examples above were finding the wrong things.

function queryParentElement(el:HTMLElement | null, selector:string) {
    let isIDSelector = selector.indexOf("#") === 0
    if (selector.indexOf('.') === 0 || selector.indexOf('#') === 0) {
        selector = selector.slice(1)
    }
    while (el) {
        if (isIDSelector) {
            if (el.id === selector) {
                return el
            }
        }
        else if (el.classList.contains(selector)) {
            return el;
        }
        el = el.parentElement;
    }
    return null;
}

To select by class name:

let elementByClassName = queryParentElement(someElement,".my-class")

To select by ID:

let elementByID = queryParentElement(someElement,"#my-element")

You should read it recursively, some time ago I had the same question and solve with this code:

public void proccessMenuNodeList(NodeList nl, JMenuBar menubar) {
    for (int i = 0; i < nl.getLength(); i++) {
        proccessMenuNode(nl.item(i), menubar);
    }
}

public void proccessMenuNode(Node n, Container parent) {
    if(!n.getNodeName().equals("menu"))
        return;
    Element element = (Element) n;
    String type = element.getAttribute("type");
    String name = element.getAttribute("name");
    if (type.equals("menu")) {
        NodeList nl = element.getChildNodes();
        JMenu menu = new JMenu(name);

        for (int i = 0; i < nl.getLength(); i++)
            proccessMenuNode(nl.item(i), menu);

        parent.add(menu);
    } else if (type.equals("item")) {
        JMenuItem item = new JMenuItem(name);
        parent.add(item);
    }
}

Probably you can adapt it for your case.

For me, this issue was proxy related. In Mac osx, even while above error is displayed, there is menu bar for Android Studio at top. Select preferences Android Studio -> Preferences and change proxy as below and issue was resolved. There could be similar options in Windows/Linux to access preferences page while error is being displayed.

This JQuery Worked for me :-

$(document).ready(function() {
  $('#con_image').on('mousedown', function(e) {
      e.preventDefault();
  });
});

I had the same error message so I went googling a bit I managed to fix it with the following code.

df<-data.frame(words = unlist(words))

words is a character list.

This just in case somebody else needs the output to be a data frame.

You can simply run this command:

npm install grunt --save-dev

I want to add that when using Windows you can use require './1.rb' if the script is run local or from a mapped network drive but when run from an UNC \\servername\sharename\folder path you need to use require_relative './1.rb'.

I don't mingle in the discussion which to use for other reasons.

For anyone else out there wondering how to do this, I have the following solution for SQL Server 2008 R2 and later:

USE master
go
DENY VIEW ANY DATABASE TO [user]
go

This will address exactly the requirement outlined above..

If you don't give any position to parent then by default it takes static. If you want to understand that difference refer to this example

Example 1::

http://jsfiddle.net/Cr9KB/1/

   #mainall
{

    background-color:red;
    height:150px;
    overflow:scroll
}

Here parent class has no position so element is placed according to body.

Example 2::

http://jsfiddle.net/Cr9KB/2/

#mainall
{
    position:relative;
    background-color:red;
    height:150px;
    overflow:scroll
}

In this example parent has relative position hence element are positioned absolute inside relative parent.

For anyone interested to implement a DropDown of custom class you can follow the bellow steps.

1. Suppose you have a class called Language with the following code and a static method which returns a List<Language>

   class Language {
     final int id;
     final String name;
     final String languageCode;
   
     const Language(this.id, this.name, this.languageCode);
   
   
   }
   
    const List<Language> getLanguages = <Language>[
           Language(1, 'English', 'en'),
           Language(2, '?????', 'fa'),
           Language(3, '????', 'ps'),
        ];
   

2. Anywhere you want to implement a DropDown you can import the Language class first use it as follow

       DropdownButton(
           underline: SizedBox(),
           icon: Icon(
                       Icons.language,
                       color: Colors.white,
                       ),
           items: getLanguages.map((Language lang) {
           return new DropdownMenuItem<String>(
                           value: lang.languageCode,
                           child: new Text(lang.name),
                         );
                       }).toList(),
   
           onChanged: (val) {
                         print(val);
                      },
         )
   

In my case, I had added an .ascx.cs into the project via right-click => "Include in Project", but the project had it set as "Content" instead of "Compile". Once I set this to "Compile", intellisense began working again.

npm fund [<pkg>]

This command retrieves information on how to fund the dependencies of a given project. If no package name is provided, it will list all dependencies that are looking for funding in a tree-structure in which are listed the type of funding and the url to visit.
The message can be disabled using: npm install --no-fund

There is already a Connect Middleware for Timeout support:

var timeout = express.timeout // express v3 and below
var timeout = require('connect-timeout'); //express v4

app.use(timeout(120000));
app.use(haltOnTimedout);

function haltOnTimedout(req, res, next){
  if (!req.timedout) next();
}

If you plan on using the Timeout middleware as a top-level middleware like above, the haltOnTimedOut middleware needs to be the last middleware defined in the stack and is used for catching the timeout event. Thanks @Aichholzer for the update.

Side Note:

Keep in mind that if you roll your own timeout middleware, 4xx status codes are for client errors and 5xx are for server errors. 408s are reserved for when:

The client did not produce a request within the time that the server was prepared to wait. The client MAY repeat the request without modifications at any later time.

If the replacement character can be '?' instead of a space, then I'd suggest result = text.encode('ascii', 'replace').decode():

"""Test the performance of different non-ASCII replacement methods."""


import re
from timeit import timeit


# 10_000 is typical in the project that I'm working on and most of the text
# is going to be non-ASCII.
text = 'Æ' * 10_000


print(timeit(
    """
result = ''.join([c if ord(c) < 128 else '?' for c in text])
    """,
    number=1000,
    globals=globals(),
))

print(timeit(
    """
result = text.encode('ascii', 'replace').decode()
    """,
    number=1000,
    globals=globals(),
))

Results:

0.7208260721400134
0.009975979187503592

I ran into the same problem after restructuring the settings as per the instructions from Daniel Greenfield's book Two scoops of Django.

I resolved the issue by setting

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project_name.settings.local")

in manage.py and wsgi.py.

Update:

In the above solution, local is the file name (settings/local.py) inside my settings folder, which holds the settings for my local environment.

Another way to resolve this issue is to keep all your common settings inside settings/base.py and then create 3 separate settings files for your production, staging and dev environments.

Your settings folder will look like:

settings/
    __init__.py
    base.py
    local.py
    prod.py
    stage.py

and keep the following code in your settings/__init__.py

from .base import *

env_name = os.getenv('ENV_NAME', 'local')

if env_name == 'prod':
    from .prod import *
elif env_name == 'stage':
    from .stage import *
else:
    from .local import *

For those who fear to mess anything up in your vscode json settings this is pretty easy to follow.

1. Open "File -> Preferences -> Keyboard Shortcuts" or "Code -> Preferences -> Keyboard Shortcuts" for Mac Users

2. In the search bar type transform.

3. By default you will not have anything under Keybinding. Now double-click on Transform to Lowercase or Transform to Uppercase.

4. Press your desired combination of keys to set your keybinding. In this case if copying off of Sublime i will press ctrl+shift+u for uppercase or ctrl+shift+l for lowercase.

5. Press Enter on your keyboard to save and exit. Do same for the other option.

6. Enjoy KEYBINDING

If your command is:

$ ssh -p 1122  path/to/pemfile user@[hostip/hostname]

You will also face the same error

ssh: Could not resolve hostname [hostname]: nodename nor servname provided, or not known

when you miss the option -i /path/to/pemfile of ssh

So Command should be:

$ ssh -p 1122 -i path/to/pemfile user@[hostip/hostname]

You may have to perform a diff and put document.getElementById('name') code inside a condition, in case your component is something like this:

// using the new hooks API
function Comp(props) {
  const { isLoading, data } = props;
  useEffect(() => {
    if (data) {
      var name = document.getElementById('name').value;
    }
  }, [data]) // this diff is necessary

  if (isLoading) return <div>isLoading</div>
  return (
    <div id='name'>Comp</div>
  );
}

If diff is not performed then, you will get null.

I have fast solution. Just create a file ImageUtil.java

import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.util.Base64;
import java.io.ByteArrayOutputStream;

public class ImageUtil
{
    public static Bitmap convert(String base64Str) throws IllegalArgumentException
    {
        byte[] decodedBytes = Base64.decode(
            base64Str.substring(base64Str.indexOf(",")  + 1),
            Base64.DEFAULT
        );

        return BitmapFactory.decodeByteArray(decodedBytes, 0, decodedBytes.length);
    }

    public static String convert(Bitmap bitmap)
    {
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, outputStream);

        return Base64.encodeToString(outputStream.toByteArray(), Base64.DEFAULT);
    }

}

Usage:

Bitmap bitmap = ImageUtil.convert(base64String);

or

String base64String = ImageUtil.convert(bitmap);

Create an ouput

<div id="output"></div>

Write to it using JavaScript

var output = document.getElementById("output");
output.innerHTML = "hello world";

If you would like it to handle more complex output values, you can use JSON.stringify

var myObj = {foo: "bar"};
output.innerHTML = JSON.stringify(myObj);

Actually, it will takes 101 bytes.

MySQL Reference

I use PHP to find the URL and match the page name (without the extension of .php, also I can add multiple pages that all have the same word in common like contact, contactform, etc. All will have that class added) and add a class with PHP to change the color, etc. For that you would have to save your pages with file extension .php.

Here is a demo. Change your links and pages as required. The CSS class for all the links is .tab and for the active link there is also another class of .currentpage (as is the PHP function) so that is where you will overwrite your CSS rules. You could name them whatever you like.

<?php # Using REQUEST_URI
    $currentpage = $_SERVER['REQUEST_URI'];?>
    <div class="nav">
        <div class="tab
             <?php
                 if(preg_match("/index/i", $currentpage)||($currentpage=="/"))
                     echo " currentpage";
             ?>"><a href="index.php">Home</a>
         </div>
         <div class="tab
             <?php
                 if(preg_match("/services/i", $currentpage))
                     echo " currentpage";
             ?>"><a href="services.php">Services</a>
         </div>
         <div class="tab
             <?php
                 if(preg_match("/about/i", $currentpage))
                     echo " currentpage";
             ?>"><a href="about.php">About</a>
         </div>
         <div class="tab
             <?php
                 if(preg_match("/contact/i", $currentpage))
                     echo " currentpage";
             ?>"><a href="contact.php">Contact</a>
         </div>
     </div> <!--nav-->

The easiest way would be to specify

SELECT productid FROM product where purchase_date > sysdate-30;

Remember this sysdate above has the time component, so it will be purchase orders newer than 03-06-2011 8:54 AM based on the time now.

If you want to remove the time conponent when comparing..

SELECT productid FROM product where purchase_date > trunc(sysdate-30);

And (based on your comments), if you want to specify a particular date, make sure you use to_date and not rely on the default session parameters.

SELECT productid FROM product where purchase_date > to_date('03/06/2011','mm/dd/yyyy')

And regardng the between (sysdate-30) - (sysdate) comment, for orders you should be ok with usin just the sysdate condition unless you can have orders with order_dates in the future.

Guys let's understand the syntax of it.

1. If class file is present in the Current Dir.

   java -cp . fileName

2. If class file is present within the Dir. Go to the Parent Dir and enter below cmd.

   java -cp . dir1.dir2.dir3.fileName

3. If there is a dependency on external jars then,

   java -cp .:./jarName1:./jarName2 fileName

   Hope this helps.

Try using

<table  border="1" cellspacing="0" cellpadding="0" class="template-table" 
style="table-layout: fixed; width: 100%"> 

as table style along with

<td style="word-break:break-word">long text</td>

for td it works for normal/real scenario text with words, not for random typed letters without gaps

I have never come across a situation where one needs to call a destructor manually. I seem to remember even Stroustrup claims it is bad practice.

There is another way of getting an element by index in jQuery using CSS :nth-of-type pseudo-class:

<script>
    // css selector that describes what you need:
    // ul li:nth-of-type(3)
    var selector = 'ul li:nth-of-type(' + index + ')';
    $(selector).css({'background-color':'#343434'});
</script>

There are other selectors that you may use with jQuery to match any element that you need.

Try to use:

String buttonText = ((Button)v).getText().toString();

Technically you don't need to install it globally if the node_modules folder in your local installation is in your PATH. Generally this isn't a good idea.

Alternatively if npm test references gulp then you can just type npm test and it'll run the local gulp.

I've never installed gulp globally -- I think it's bad form.

Updated with the theme() function, ggsave() and the code for the legend background:

df <- data.frame(y = d, x = 1, group = rep(c("gr1", "gr2"), 50))
p <- ggplot(df) +
  stat_boxplot(aes(x = x, y = y, color = group), 
               fill = "transparent" # for the inside of the boxplot
  ) 

Fastest way is using using rect, as all the rectangle elements inherit from rect:

p <- p +
  theme(
        rect = element_rect(fill = "transparent") # all rectangles
      )
    p

More controlled way is to use options of theme:

p <- p +
  theme(
    panel.background = element_rect(fill = "transparent"), # bg of the panel
    plot.background = element_rect(fill = "transparent", color = NA), # bg of the plot
    panel.grid.major = element_blank(), # get rid of major grid
    panel.grid.minor = element_blank(), # get rid of minor grid
    legend.background = element_rect(fill = "transparent"), # get rid of legend bg
    legend.box.background = element_rect(fill = "transparent") # get rid of legend panel bg
  )
p

To save (this last step is important):

ggsave(p, filename = "tr_tst2.png",  bg = "transparent")

There is a workaround which may help. You may "register" results for each set_fact iteration and then map that results to list:

---
- hosts: localhost
  tasks:
  - name: set fact
    set_fact: foo_item="{{ item }}"
    with_items:
      - four
      - five
      - six
    register: foo_result

  - name: make a list
    set_fact: foo="{{ foo_result.results | map(attribute='ansible_facts.foo_item') | list }}"

  - debug: var=foo

Output:

< TASK: debug var=foo >
 ---------------------
    \   ^__^
     \  (oo)\_______
        (__)\       )\/\
            ||----w |
            ||     ||


ok: [localhost] => {
    "var": {
        "foo": [
            "four", 
            "five", 
            "six"
        ]
    }
}

Well, you're getting a java.lang.NoClassDefFoundError. In your pom.xml, hibernate-core version is 3.3.2.GA and declared after hibernate-entitymanager, so it prevails. You can remove that dependency, since will be inherited version 3.6.7.Final from hibernate-entitymanager.

You're using spring-boot as parent, so no need to declare version of some dependencies, since they are managed by spring-boot.

Also, hibernate-commons-annotations is inherited from hibernate-entitymanager and hibernate-annotations is an old version of hibernate-commons-annotations, you can remove both.

Finally, your pom.xml can look like this:

Let me know if you have a problem.

From the documentation on http://curl.haxx.se/docs/httpscripting.html :

HTTP Authentication

curl --user name:password http://www.example.com 

Put a file to a HTTP server with curl:

curl --upload-file uploadfile http://www.example.com/receive.cgi

Send post data with curl:

curl --data "birthyear=1905&press=%20OK%20" http://www.example.com/when.cgi

If you want to make an empty data frame and add contents in a loop, the following may help:

# Number of students in class
student.count <- 36

# Gather data about the students
student.age <- sample(14:17, size = student.count, replace = TRUE)
student.gender <- sample(c('male', 'female'), size = student.count, replace = TRUE)
student.marks <- sample(46:97, size = student.count, replace = TRUE)

# Create empty data frame
student.data <- data.frame()

# Populate the data frame using a for loop
for (i in 1 : student.count) {
    # Get the row data
    age <- student.age[i]
    gender <- student.gender[i]
    marks <- student.marks[i]

    # Populate the row
    new.row <- data.frame(age = age, gender = gender, marks = marks)

    # Add the row
    student.data <- rbind(student.data, new.row)
}

# Print the data frame
student.data

Hope it helps :)

in order to clean automatically .sock file, place these lines in file /etc/init.d/mysqld immediately after "start)" block of code

test -e /var/lib/mysql/mysql.sock
SOCKEXIST=$?

ps cax | grep mysqld_safe
NOPIDMYSQL=$?

echo NOPIDMYSQL $NOPIDMYSQL
echo SOCKEXIST $SOCKEXIST

if [ $NOPIDMYSQL -eq 1 ] && [ $SOCKEXIST -eq 0 ] ; then
    echo "NOT CLEAN"
    rm -f /var/lib/mysql/mysql.sock
    echo "FILE SOCK REMOVED"
else
    echo "CLEAN"
fi

it worked for me. I had to do this because I have not an UPS and often we have power supply failures.

regards.

This will submit the right form response (i.e. Select value most of the time, and Input value when the Select box is set to "others"). Uses jQuery:

  $("select[name="color"]").change(function(){
    new_value = $(this).val();
    if (new_value == "others") {
      $('input[name="color"]').show();      
    } else {
      $('input[name="color"]').val(new_value);
      $('input[name="color"]').hide();
    }
  });

You can access parent window using 'window.opener', so, write something like the following in the child window:

<script>
    window.onunload = refreshParent;
    function refreshParent() {
        window.opener.location.reload();
    }
</script>

This is useful when you want to have a global variable. You define the global variables in some source file, and declare them extern in a header file so that any file that includes that header file will then see the same global variable.

Put into a script I like something like that:

#!/bin/bash
set -o xtrace # remove me after debug
TABLE=some_table_name
DB_NAME=prod_database

BASE_DIR=/var/backups/someDir
LOCATION="${BASE_DIR}/myApp_$(date +%Y%m%d_%H%M%S)"
FNAME="${LOCATION}_${DB_NAME}_${TABLE}.sql"

# Create backups directory if not exists
if [[ ! -e $BASE_DIR ]];then
       mkdir $BASE_DIR
       chown -R postgres:postgres $BASE_DIR
fi

sudo -H -u postgres pg_dump --column-inserts --data-only --table=$TABLE $DB_NAME > $FNAME
sudo gzip $FNAME

Duplicate question which basically says use ExecuteScalar() instead.

You should apply the following styles:

#button:active {
    vertical-align: top;
    padding: 8px 13px 6px;
}

This will give you the necessary effect, demo here.

.prop("clientWidth") and .prop("scrollWidth")

var actualInnerWidth = $("body").prop("clientWidth"); // El. width minus scrollbar width
var actualInnerWidth = $("body").prop("scrollWidth"); // El. width minus scrollbar width

in JavaScript:

var actualInnerWidth = document.body.clientWidth;     // El. width minus scrollbar width
var actualInnerWidth = document.body.scrollWidth;     // El. width minus scrollbar width

_{P.S: Note that to use scrollWidth reliably your element should not overflow horizontally}

jsBin demo

You could also use .innerWidth() but this will work only on the body element

var innerWidth = $('body').innerWidth(); // Width PX minus scrollbar 

d = DateTime.now.utc

Oops!

That seems to work in Rails, but not vanilla Ruby (and of course that is what the question is asking)

d = Time.now.utc

Does work however.

Is there any reason you need to use DateTime and not Time? Time should include everything you need:

irb(main):016:0> Time.now
=> Thu Apr 16 12:40:44 +0100 2009

You can have return in a void method, you just can't return any value (as in return 5;), that's why they call it a void method. Some people always explicitly end void methods with a return statement, but it's not mandatory. It can be used to leave a function early, though:

void someFunct(int arg)
{
    if (arg == 0)
    {
        //Leave because this is a bad value
        return;
    }
    //Otherwise, do something
}

• When you use .getClass().getResource(fileName) it considers the location of the fileName is the same location of the of the calling class.
• When you use .getClass().getClassLoader().getResource(fileName) it considers the location of the fileName is the root - in other words bin folder.

Source :

package Sound;
public class ResourceTest {
    public static void main(String[] args) {
        String fileName = "Kalimba.mp3";
        System.out.println(fileName);
        System.out.println(new ResourceTest().getClass().getResource(fileName));
        System.out.println(new ResourceTest().getClass().getClassLoader().getResource(fileName));
    }

I've got a YouTube video on this.

Short answer: Use mock when you're passing in the thing that you want mocked, and patch if you're not. Of the two, mock is strongly preferred because it means you're writing code with proper dependency injection.

Silly example:

# Use a mock to test this.
my_custom_tweeter(twitter_api, sentence):
    sentence.replace('cks','x')   # We're cool and hip.
    twitter_api.send(sentence)

# Use a patch to mock out twitter_api. You have to patch the Twitter() module/class 
# and have it return a mock. Much uglier, but sometimes necessary.
my_badly_written_tweeter(sentence):
    twitter_api = Twitter(user="XXX", password="YYY")
    sentence.replace('cks','x') 
    twitter_api.send(sentence)

Create a procedure which just does your lock and install it into a different user, who is "trusted" with dbms_lock ( USERA ), grant USERA access to dbms_lock.

Then just grant USERB access to this function. They then wont need to be able to access DBMS_LOCK

( make sure you don't have usera and userb in your system before running this )

Connect as a user with grant privs for dbms_lock, and can create users

drop user usera cascade;
drop user userb cascade;
create user usera default tablespace users identified by abc123;
grant create session to usera;
grant resource to usera;
grant execute on dbms_lock to usera;

create user userb default tablespace users identified by abc123;
grant create session to userb;
grant resource to useb

connect usera/abc123;

create or replace function usera.f_sleep( in_time number ) return number is
begin
 dbms_lock.sleep(in_time);
 return 1;
end;
/

grant execute on usera.f_sleep to userb;

connect userb/abc123;

/* About to sleep as userb */
select usera.f_sleep(5) from dual;
/* Finished sleeping as userb */

/* Attempt to access dbms_lock as userb.. Should fail */

begin
  dbms_lock.sleep(5);
end;
/

/* Finished */

unbind() doesn't work with hardcoded inline events.

So, for example, if you want to unbind the mouseover event from <div id="some_div" onmouseover="do_something();">, I found that $('#some_div').attr('onmouseover','') is a quick and dirty way to achieve it.

Just in case if anyone reached here looking for solution, here is how i resolved it. By mistake I deleted all files from my server ( bin directory ) but when i recopied all files i missed App_global.asax.dll and App_global.asax.compiled files. Because these files were missing IIS was giving me this error

403 - Forbidden: Access is denied.

As soon as i added these files, it started working perfectly fine.

Among the answers given here before this one, the one by "Yes Barry" is the most appropriate one.

random_int(100000, 999999)

Note that here we use random_int, which was introduced in PHP 7 and uses a cryptographic random generator, something that is important if you want random codes to be hard to guess. random_bytes was also introduced in PHP 7 and likewise uses a cryptographic random generator.

Many other solutions for random value generation, including those involving time(), microtime(), uniqid(), rand(), mt_rand(), str_shuffle(), and array_rand(), are much more predictable and are unsuitable if the random string will serve as a password, a bearer credential, a nonce, a session identifier, a "verification code" or "confirmation code", or another secret value.

The code above generates a string of 6 decimal digits. If you want to use a bigger character set (such as all upper-case letters, all lower-case letters, and the 10 digits), this is a more involved process, but you have to use random_int or random_bytes rather than rand(), mt_rand(), str_shuffle(), etc., if the string will serve as a password, a "confirmation code", or another secret value. See an answer to a related question, and see also: generating a random code in php?

I also list other things to keep in mind when generating unique identifiers, especially random ones.

Using generators, it is quite simple:

signal = ['?Signal value?']
def pniter( iter, signal=signal ):
    iA = iB = signal
    for iC in iter:
        if iB is signal:
            iB = iC
            continue
        else:
            yield iA, iB, iC
        iA = iB
        iB = iC
    iC = signal
    yield iA, iB, iC

if __name__ == '__main__':
    print('test 1:')
    for a, b, c in pniter( range( 10 )):
        print( a, b, c )
    print('\ntest 2:')
    for a, b, c in pniter([ 20, 30, 40, 50, 60, 70, 80 ]):
        print( a, b, c )
    print('\ntest 3:')
    cam = { 1: 30, 2: 40, 10: 9, -5: 36 }
    for a, b, c in pniter( cam ):
        print( a, b, c )
    for a, b, c in pniter( cam ):
        print( a, a if a is signal else cam[ a ], b, b if b is signal else cam[ b ], c, c if c is signal else cam[ c ])
    print('\ntest 4:')
    for a, b, c in pniter([ 20, 30, None, 50, 60, 70, 80 ]):
        print( a, b, c )
    print('\ntest 5:')
    for a, b, c in pniter([ 20, 30, None, 50, 60, 70, 80 ], ['sig']):
        print( a, b, c )
    print('\ntest 6:')
    for a, b, c in pniter([ 20, ['?Signal value?'], None, '?Signal value?', 60, 70, 80 ], signal ):
        print( a, b, c )

Note that tests that include None and the same value as the signal value still work, because the check for the signal value uses "is" and the signal is a value that Python doesn't intern. Any singleton marker value can be used as a signal, though, which might simplify user code in some circumstances.

I use static classes as a means to define "extra functionality" that an object of a given type could use under a specific context. Usually they turn out to be utility classes.

Other than that, I think that "Use a static class as a unit of organization for methods not associated with particular objects." describe quite well their intended usage.

In recent versions of major browsers you can use backdrop-filter property.

HTML

<div>backdrop blur</div>

CSS

div {
    -webkit-backdrop-filter: blur(10px);
    backdrop-filter: blur(10px);
}

or if you need different background color for browsers without support:

div {
    background-color: rgba(255, 255, 255, 0.9);
}

@supports (-webkit-backdrop-filter: none) or (backdrop-filter: none) {
    div {
        -webkit-backdrop-filter: blur(10px);
        backdrop-filter: blur(10px);
        background-color: rgba(255, 255, 255, 0.5);  
    }
}

Looking at man 3 printf on Linux, OS X, and OpenBSD all show support for %z for size_t and %t for ptrdiff_t (for C99), but none of those mention off_t. Suggestions in the wild usually offer up the %u conversion for off_t, which is "correct enough" as far as I can tell (both unsigned int and off_t vary identically between 64-bit and 32-bit systems).

Simple solution is to embed inside of a <textarea> element, which will preserve both the formatting and the angle brackets. I have also removed the border with style="border:none;" which makes the textarea invisible.

Here is a sample: http://jsfiddle.net/y9fqf/1/

What I have done here is that I have returned a promise from the justTesting function. You can then get the result when the function is resolved.

// new answer

function justTesting() {
  return new Promise((resolve, reject) => {
    if (true) {
      return resolve("testing");
    } else {
      return reject("promise failed");
   }
 });
}

justTesting()
  .then(res => {
     let test = res;
     // do something with the output :)
  })
  .catch(err => {
    console.log(err);
  });

Hope this helps!

// old answer

function justTesting() {
  return promise.then(function(output) {
    return output + 1;
  });
}

justTesting().then((res) => {
     var test = res;
    // do something with the output :)
    }

You can try:

string s1 = Regex.Replace(s, "[^A-Za-z0-9 -]", "");

Where s is your string.

go plain for SWIFT 3 and APACHE simple Auth:

func urlSession(_ session: URLSession, task: URLSessionTask,
                didReceive challenge: URLAuthenticationChallenge,
                completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) {

    let credential = URLCredential(user: "test",
                                   password: "test",
                                   persistence: .none)

    completionHandler(.useCredential, credential)


}

I use this SQL code to get all the information about a column.

SELECT
COL.COLUMN_NAME,
ORDINAL_POSITION,
DATA_TYPE,
CHARACTER_MAXIMUM_LENGTH,
NUMERIC_PRECISION,
NUMERIC_PRECISION_RADIX,
NUMERIC_SCALE,
DATETIME_PRECISION,

CONSTRAINT_TYPE,
COLUMNPROPERTY(object_id(COL.TABLE_NAME), COL.COLUMN_NAME, 'IsIdentity') IS_IDENTITY,
COLUMNPROPERTY(object_id(COL.TABLE_NAME), COL.COLUMN_NAME, 'IsComputed') IS_COMPUTED

FROM INFORMATION_SCHEMA.COLUMNS COL 
LEFT OUTER JOIN 
(
    SELECT COLUMN_NAME, CONSTRAINT_TYPE 
    FROM INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE A
    INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS B 
    ON A.CONSTRAINT_NAME = B.CONSTRAINT_NAME
    WHERE A.TABLE_NAME = 'User'
) CONS
ON COL.COLUMN_NAME = CONS.COLUMN_NAME
WHERE COL.TABLE_NAME = 'User'

There are many plugins for doing that. I normally use datatables it works great. http://datatables.net/

As of right now, I do not know of any. It appears the code academy folks have set their sites on Ruby on Rails. They do not rule Java out of the picture however.

If your trying to fade the backgound image but leave the foreground text/images you could use css to separate the background image into a new div and position it over the div containing the text/images then fade the background div.

I edited the solution file and changed localhost to my ip address. Before that I had added IIS_IUSRS with full control in the project directory. I can now debug.

For this case: user signup form, user must choose a username that is not taken.

This means we have to create a customized validation rule, which will send async http request with remote server.

1. create a input element in your html:

<input name="user_name" type="text" >

2. declare your form validation rules:

  $("form").validate({
    rules: {
      'user_name': {
        //  here jquery validate will start a GET request, to 
        //  /interface/users/is_username_valid?user_name=<input_value>
        //  the response should be "raw text", with content "true" or "false" only
        remote: '/interface/users/is_username_valid'
      },
    },

3. the remote code should be like:

class Interface::UsersController < ActionController::Base
  def is_username_valid
    render :text => !User.exists?(:user_name => params[:user_name])
  end
end

If you want to set the precision for all decimals in EF6 you could replace the default DecimalPropertyConvention convention used in the DbModelBuilder:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    modelBuilder.Conventions.Remove<DecimalPropertyConvention>();
    modelBuilder.Conventions.Add(new DecimalPropertyConvention(38, 18));
}

The default DecimalPropertyConvention in EF6 maps decimal properties to decimal(18,2) columns.

If you only want individual properties to have a specified precision then you can set the precision for the entity's property on the DbModelBuilder:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    modelBuilder.Entity<MyEntity>().Property(e => e.Value).HasPrecision(38, 18);
}

Or, add an EntityTypeConfiguration<> for the entity which specifies the precision:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    modelBuilder.Configurations.Add(new MyEntityConfiguration());
}

internal class MyEntityConfiguration : EntityTypeConfiguration<MyEntity>
{
    internal MyEntityConfiguration()

The popular answer google.maps.event.trigger(map, "resize"); didn't work for me alone.

Here was a trick that assured that the page had loaded and that the map had loaded as well. By setting a listener and listening for the idle state of the map you can then call the event trigger to resize.

$(document).ready(function() {
    google.maps.event.addListener(map, "idle", function(){
        google.maps.event.trigger(map, 'resize'); 
    });
}); 

This was my answer that worked for me.

Make a bypass API in server.js. This works for me.

app.post('/by-pass-api',function(req, response){
  const url = req.body.url;
  console.log("calling url", url);
  request.get(
    url,
    (error, res, body) => {
      if (error) {
        console.error(error)
        return response.status(200).json({'content': "error"}) 
}
        return response.status(200).json(JSON.parse(body))
        },
      )
    })

And call it using axios or fetch like this:

const options = {
     method: 'POST',
     headers: {'content-type': 'application/json'},
     url:`http://localhost:3000/by-pass-api`, // your environment 
     data: { url },  // your https request here
    };

>>> s1 ='arbit'
>>> s2 = 'hello world '.join( [s]*3 )
>>> print s2
arbit hello world arbit hello world arbit

this fails:

 DECLARE @vPortalUID NVARCHAR(32)
 SET @vPortalUID='2A66057D-F4E5-4E2B-B2F1-38C51A96D385'
 DECLARE @nPortalUID AS UNIQUEIDENTIFIER
 SET @nPortalUID = CAST(@vPortalUID AS uniqueidentifier)
 PRINT @nPortalUID

this works

 DECLARE @vPortalUID NVARCHAR(36)
 SET @vPortalUID='2A66057D-F4E5-4E2B-B2F1-38C51A96D385'
 DECLARE @nPortalUID AS UNIQUEIDENTIFIER
 SET @nPortalUID = CAST(@vPortalUID AS UNIQUEIDENTIFIER)
 PRINT @nPortalUID

the difference is NVARCHAR(36), your input parameter is too small!

Google has created a library for easy Permissions management. Its called EasyPermissions

Here is a simple example on requesting Location permission using this library.

public class MainActivity extends AppCompatActivity {

    private final int REQUEST_LOCATION_PERMISSION = 1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        requestLocationPermission();
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);

        // Forward results to EasyPermissions
        EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);
    }

    @AfterPermissionGranted(REQUEST_LOCATION_PERMISSION)
    public void requestLocationPermission() {
        String[] perms = {Manifest.permission.ACCESS_FINE_LOCATION};
        if(EasyPermissions.hasPermissions(this, perms)) {
            Toast.makeText(this, "Permission already granted", Toast.LENGTH_SHORT).show();
        }
        else {
            EasyPermissions.requestPermissions(this, "Please grant the location permission", REQUEST_LOCATION_PERMISSION, perms);
        }
    }
}

@AfterPermissionsGranted(REQUEST_CODE) is used to indicate the method that needs to be executed after a permission request with the request code REQUEST_CODE has been granted.

This above case, the method requestLocationPermission() method is called if the user grants the permission to access location services. So, that method acts as both a callback and a method to request the permissions.

You can implement separate callbacks for permission granted and permission denied as well. It is explained in the github page.

USING POD

<?php
$username = "root";
$password = "";
$db = "db_name";

$dns = "mysql:host=localhost;dbname=$db;charset=utf8mb4";
    $conn = new PDO($dns,$username, $password);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $sql = "select * from mine where username = ? ";

    $stmt1 = $conn->prepare($sql);
    $stmt1 -> execute(array($_POST['user']));
    $all = $stmt1->fetchAll(); ?>

    <div class="controls">
        <select  data-rel="chosen"  name="degree_id" id="selectError">

                 <?php foreach($all as $nt) { echo "<option value =$nt[id]>$nt[name]</option>";}?>
        </select>

    </div>

In addition to Jim's answer (sorry not enough rep points to make a comment), just wanted to point out that the arguments specified in PyCharm do not have special characters escaped, unlike what you would do on the command line. So, whereas on the command line you'd do:

python mediadb.py  /media/paul/New\ Volume/Users/paul/Documents/spinmaster/\*.png

the PyCharm parameter would be:

"/media/paul/New Volume/Users/paul/Documents/spinmaster/*.png"

Input masks can be implemented using a combination of the keyup event, and the HTMLInputElement value, selectionStart, and selectionEnd properties. Here's a very simple implementation which does some of what you want. It's certainly not perfect, but works well enough to demonstrate the principle:

Array.prototype.forEach.call(document.body.querySelectorAll("*[data-mask]"), applyDataMask);_x000D_
_x000D_
function applyDataMask(field) {_x000D_
    var mask = field.dataset.mask.split('');_x000D_
    _x000D_
    // For now, this just strips everything that's not a number_x000D_
    function stripMask(maskedData) {_x000D_
        function isDigit(char) {_x000D_
            return /\d/.test(char);_x000D_
        }_x000D_
        return maskedData.split('').filter(isDigit);_x000D_
    }_x000D_
    _x000D_
    // Replace `_` characters with characters from `data`_x000D_
    function applyMask(data) {_x000D_
        return mask.map(function(char) {_x000D_
            if (char != '_') return char;_x000D_
            if (data.length == 0) return char;_x000D_
            return data.shift();_x000D_
        }).join('')_x000D_
    }_x000D_
    _x000D_
    function reapplyMask(data) {_x000D_
        return applyMask(stripMask(data));_x000D_
    }_x000D_
    _x000D_
    function changed() {   _x000D_
        var oldStart = field.selectionStart;_x000D_
        var oldEnd = field.selectionEnd;_x000D_
        _x000D_
        field.value = reapplyMask(field.value);_x000D_
        _x000D_
        field.selectionStart = oldStart;_x000D_
        field.selectionEnd = oldEnd;_x000D_
    }_x000D_
    _x000D_
    field.addEventListener('click', changed)_x000D_
    field.addEventListener('keyup', changed)_x000D_
}

ISO Date: <input type="text" value="____-__-__" data-mask="____-__-__"/><br/>_x000D_
Telephone: <input type="text" value="(___) ___-____" data-mask="(___) ___-____"/><br/>

(View in JSFiddle)

There are also a number of libraries out there which perform this function. Some examples include:

• jquery.inputmask
• MASKED INPUT PLUGIN
• Politespace (presents an alternative to input masks)

In my case

[assembly: System.Resources.NeutralResourcesLanguage("ru-RU")]

in the AssemblyInfo.cs prevented things to work as usual.

The following document linked from the draft RFC mentioned by Jim in his answer further addresses the question and definitely worth a direct note here:

Test Cases for HTTP Content-Disposition header and RFC 2231/2047 Encoding

I've found this question while I was trying to solve my issue with running sequelize seed:generate cli command:

node_modules/.bin/sequelize seed:generate --name=user

Let me get to the point. I wanted to have a short script command in my package.json file and to provide --name argument at the same time

The answer came after some experiments. Here is my command in package.json

"scripts: {
  "seed:generate":"NODE_ENV=development node_modules/.bin/sequelize seed:generate"
}

... and here is an example of running it in terminal to generate a seed file for a user

> yarn seed:generate --name=user

> npm run seed:generate -- --name=user

FYI

yarn -v
1.6.0

npm -v
5.6.0

Use this code if you want to change all tables, views, and procedures at once.

BEGIN
DECLARE @name NVARCHAR(MAX)
        , @sql NVARCHAR(MAX)
        , @oldSchema NVARCHAR(MAX) = 'MyOldSchema'
        , @newSchema NVARCHAR(MAX) = 'dbo'
        
DECLARE objCursor CURSOR FOR
        SELECT  o.name
        FROM    sys.objects o
        WHERE   type IN ('P', 'U', 'V')

OPEN    objCursor
        FETCH NEXT FROM objCursor INTO @name
        WHILE   @@FETCH_STATUS = 0
        BEGIN
            SET @sql = 'ALTER SCHEMA '+ @newSchema +' TRANSFER '+ @oldSchema + '.' +  @name         
            BEGIN TRY
                exec(@sql)
                PRINT 'Success: ' + @sql
            END TRY
            BEGIN CATCH
                PRINT 'Error executing: ' + @sql
            END CATCH
            FETCH NEXT FROM objCursor INTO @name
        END
CLOSE   objCursor
DEALLOCATE  objCursor

END

It will execute a code like this

ALTER SCHEMA dbo TRANSFER MyOldSchema.xx_GetUserInformation

There is a plugin, adampietrasiak/jquery.initialize, which is based on MutationObserver that achieves this simply.

$.initialize(".some-element", function() {
    $(this).css("color", "blue");
});

There's also the QueryString module's parse() method:

var http = require('http'),
    queryString = require('querystring');

http.createServer(function (oRequest, oResponse) {

    var oQueryParams;

    // get query params as object
    if (oRequest.url.indexOf('?') >= 0) {
        oQueryParams = queryString.parse(oRequest.url.replace(/^.*\?/, ''));

        // do stuff
        console.log(oQueryParams);
    }

    oResponse.writeHead(200, {'Content-Type': 'text/plain'});
    oResponse.end('Hello world.');

}).listen(1337, '127.0.0.1');

If you want something lighter than a Label or other ASP.NET-specific server control you can just use a standard HTML DIV or SPAN and with runat="server", e.g.:

Markup:

<span runat="server" id="FooSpan"></span>

Code:

FooSpan.Text = "Foo";

HTML:

<div id="myElement">Rounded Corner Box</div>

CSS:

#myElement {
    background: #EEE;
    padding: 2em;
    -moz-border-radius: 1em;
    -webkit-border-radius: 1em;
    border-radius: 1em;
    behavior: url(PIE.htc);
    border: 1px solid red;

}

PIE.htc file can be downloaded from http://www.css3pie.com

My Solution to this problem is

<li class="@(Context.Request.Path.Value.ToLower().Contains("about") ? "active " : "" ) nav-item">
                <a class="nav-link" asp-area="" asp-controller="Home" asp-action="About">About</a>
            </li>

A better way may be adding an Html extension method to return the current path to be compared with link

Based on @MichalPerlakowski answer (EcmaScipt 6) and his answer based on Tim Down's answer

I wrote a modified version of the function of converting hexToRGB with the addition of safe checking if the r/g/b color components are between 0-255 and also the funtions can take Number r/g/b params or String r/g/b parameters and here it is:

 function rgbToHex(r, g, b) {
     r = Math.abs(r);
     g = Math.abs(g);
     b = Math.abs(b);

     if ( r < 0 ) r = 0;
     if ( g < 0 ) g = 0;
     if ( b < 0 ) b = 0;

     if ( r > 255 ) r = 255;
     if ( g > 255 ) g = 255;
     if ( b > 255 ) b = 255;

    return '#' + [r, g, b].map(x => {
      const hex = x.toString(16);
      return hex.length === 1 ? '0' + hex : hex
    }).join('');
  }

To use the function safely - you should ckeck whether the passing string is a real rbg string color - for example a very simple check could be:

if( rgbStr.substring(0,3) === 'rgb' ) {

  let rgbColors = JSON.parse(rgbStr.replace('rgb(', '[').replace(')', ']'))
  rgbStr = this.rgbToHex(rgbColors[0], rgbColors[1], rgbColors[2]);

  .....
}

A faster solution is provided by Kevin P. Rice here:https://stackoverflow.com/a/11595914/5535820 So here's the code:

function leapYear(year)
{
    return (year & 3) == 0 && ((year % 25) != 0 || (year & 15) == 0);
}

Please use this code.

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss"]; 
[dateFormatter setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"UTC"]];
NSDate *date = [dateFormatter dateFromString:@"2015-04-01T11:42:00"]; // create date from string

[dateFormatter setDateFormat:@"EEE, MMM d, yyyy - h:mm a"];
[dateFormatter setTimeZone:[NSTimeZone localTimeZone]];
NSString *timestamp = [dateFormatter stringFromDate:date];

I met the same problem as you.

I push two tables result into t1 object and group t1.

 from p in Products                         
  join bp in BaseProducts on p.BaseProductId equals bp.Id
  select new {
   p,
   bp
  } into t1
 group t1 by t1.p.SomeId into g
 select new ProductPriceMinMax { 
  SomeId = g.FirstOrDefault().p.SomeId, 
  CountryCode = g.FirstOrDefault().p.CountryCode, 
  MinPrice = g.Min(m => m.bp.Price), 
  MaxPrice = g.Max(m => m.bp.Price),
  BaseProductName = g.FirstOrDefault().bp.Name
};

If you want to start at the "application root" as you describe right click on the top level Default.aspx page and choose set as start page. Hit F5 and you're done.

If you want to start at a different controller action see Mark's answer.

Add the css styling text-align: center to the control.

Ideally you would do this through a css class assigned to the control, but if you must do it directly, here is an example:

<asp:TextBox ID="myTextBox" runat="server" style="text-align: center"></asp:TextBox>

I'm the author of the AI program that others have mentioned in this thread. You can view the AI in action or read the source.

Currently, the program achieves about a 90% win rate running in javascript in the browser on my laptop given about 100 milliseconds of thinking time per move, so while not perfect (yet!) it performs pretty well.

Since the game is a discrete state space, perfect information, turn-based game like chess and checkers, I used the same methods that have been proven to work on those games, namely minimax search with alpha-beta pruning. Since there is already a lot of info on that algorithm out there, I'll just talk about the two main heuristics that I use in the static evaluation function and which formalize many of the intuitions that other people have expressed here.

Monotonicity

This heuristic tries to ensure that the values of the tiles are all either increasing or decreasing along both the left/right and up/down directions. This heuristic alone captures the intuition that many others have mentioned, that higher valued tiles should be clustered in a corner. It will typically prevent smaller valued tiles from getting orphaned and will keep the board very organized, with smaller tiles cascading in and filling up into the larger tiles.

Here's a screenshot of a perfectly monotonic grid. I obtained this by running the algorithm with the eval function set to disregard the other heuristics and only consider monotonicity.

Smoothness

The above heuristic alone tends to create structures in which adjacent tiles are decreasing in value, but of course in order to merge, adjacent tiles need to be the same value. Therefore, the smoothness heuristic just measures the value difference between neighboring tiles, trying to minimize this count.

A commenter on Hacker News gave an interesting formalization of this idea in terms of graph theory.

Here's a screenshot of a perfectly smooth grid, courtesy of this excellent parody fork.

Free Tiles

And finally, there is a penalty for having too few free tiles, since options can quickly run out when the game board gets too cramped.

And that's it! Searching through the game space while optimizing these criteria yields remarkably good performance. One advantage to using a generalized approach like this rather than an explicitly coded move strategy is that the algorithm can often find interesting and unexpected solutions. If you watch it run, it will often make surprising but effective moves, like suddenly switching which wall or corner it's building up against.

Edit:

Here's a demonstration of the power of this approach. I uncapped the tile values (so it kept going after reaching 2048) and here is the best result after eight trials.

Yes, that's a 4096 alongside a 2048. =) That means it achieved the elusive 2048 tile three times on the same board.

No.

The content-type should be whatever it is known to be, if you know it. application/octet-stream is defined as "arbitrary binary data" in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be saved to disk, and from that point on be outside of anything "webby". Or to look at it from another direction; the only thing one can safely do with application/octet-stream is to save it to file and hope someone else knows what it's for.

You can combine the use of Content-Disposition with other content-types, such as image/png or even text/html to indicate you want saving rather than display. It used to be the case that some browsers would ignore it in the case of text/html but I think this was some long time ago at this point (and I'm going to bed soon so I'm not going to start testing a whole bunch of browsers right now; maybe later).

RFC 2616 also mentions the possibility of extension tokens, and these days most browsers recognise inline to mean you do want the entity displayed if possible (that is, if it's a type the browser knows how to display, otherwise it's got no choice in the matter). This is of course the default behaviour anyway, but it means that you can include the filename part of the header, which browsers will use (perhaps with some adjustment so file-extensions match local system norms for the content-type in question, perhaps not) as the suggestion if the user tries to save.

Hence:

Content-Type: application/octet-stream
Content-Disposition: attachment; filename="picture.png"

Means "I don't know what the hell this is. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: attachment; filename="picture.png"

Means "This is a PNG image. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: inline; filename="picture.png"

Means "This is a PNG image. Please display it unless you don't know how to display PNG images. Otherwise, or if the user chooses to save it, we recommend the name picture.png for the file you save it as".

Of those browsers that recognise inline some would always use it, while others would use it if the user had selected "save link as" but not if they'd selected "save" while viewing (or at least IE used to be like that, it may have changed some years ago).

I tried this code and it's working for me .

$html = file_get_contents('www.google.com');
$myVar = htmlspecialchars($html, ENT_QUOTES);
echo($myVar);

You can also override the deployment repository on the command line: -Darguments=-DaltDeploymentRepository=myreposid::default::http://my/url/releases

AFAIR, MySQL implements INTERSECT through INNER JOIN.

• I've got the same info messages and error message today, but I have recently updated Idea -> 2018.3.3, built on January 9, 2019.

• To resolve this issue I've changed File->Project Structure->Modules ->> Language level to 10.

• And check File -> Settings -> Build, Execution, Deployment -> Compiler -> Java Compiler ->> Project bytecode and Per-module bytecode versions. I have 11 there.

• Now I don't get these notifications and the error.

  It could be useful for someone like me, having the most recent Idea and getting the same error.

The methods here that show the actual implementation are all faulty.
I don't have Java code, but just for the record, you could easily convert this C#-code:

You can also change the value of this database parameter for your session by using the ALTER SESSION command and use it as you wanted

ALTER SESSION SET NLS_DATE_FORMAT = 'DD-MM-YYYY';
SELECT TO_DATE('05-12-2015') FROM dual;

UPDATE: matplotlib.mlab.PCA is since release 2.2 (2018-03-06) indeed deprecated.

The library matplotlib.mlab.PCA (used in this answer) is not deprecated. So for all the folks arriving here via Google, I'll post a complete working example tested with Python 2.7.

Use the following code with care as it uses a now deprecated library!

from matplotlib.mlab import PCA
import numpy
data = numpy.array( [[3,2,5], [-2,1,6], [-1,0,4], [4,3,4], [10,-5,-6]] )
pca = PCA(data)

Now in `pca.Y' is the original data matrix in terms of the principal components basis vectors. More details about the PCA object can be found here.

>>> pca.Y
array([[ 0.67629162, -0.49384752,  0.14489202],
   [ 1.26314784,  0.60164795,  0.02858026],
   [ 0.64937611,  0.69057287, -0.06833576],
   [ 0.60697227, -0.90088738, -0.11194732],
   [-3.19578784,  0.10251408,  0.00681079]])

You can use matplotlib.pyplot to draw this data, just to convince yourself that the PCA yields "good" results. The names list is just used to annotate our five vectors.

import matplotlib.pyplot
names = [ "A", "B", "C", "D", "E" ]
matplotlib.pyplot.scatter(pca.Y[:,0], pca.Y[:,1])
for label, x, y in zip(names, pca.Y[:,0], pca.Y[:,1]):
    matplotlib.pyplot.annotate( label, xy=(x, y), xytext=(-2, 2), textcoords='offset points', ha='right', va='bottom' )
matplotlib.pyplot.show()

Looking at our original vectors we'll see that data[0] ("A") and data[3] ("D") are rather similar as are data[1] ("B") and data[2] ("C"). This is reflected in the 2D plot of our PCA transformed data.

Under compiler.xml file you will find :

<bytecodeTargetLevel>
  <module name="your_project_name_main" target="1.8" />
  <module name="your_project_name_test" target="1.8" />
</bytecodeTargetLevel>

and you can change the target value from your old to the new for me i needed to change it from 1.5 to 1.8

bind tells the running process to claim a port. i.e, it should bind itself to port 80 and listen for incomming requests. with bind, your process becomes a server. when you use connect, you tell your process to connect to a port that is ALREADY in use. your process becomes a client. the difference is important: bind wants a port that is not in use (so that it can claim it and become a server), and connect wants a port that is already in use (so it can connect to it and talk to the server)

For python 3

First install module:

pip3 install gitpython

and later, code it :)

import os
from git.repo.base import Repo
Repo.clone_from("https://github.com/*****", "folderToSave")

I hope this helps you

I think a good place to start is with Ninject, it is new and has taken into account alot of fine tuning and is really fast. Nate, the developer, really has a great site and great support.

The following should work for a JSON returned string. It will also work for an associative array of data.

for (var key in data)
     alert(key + ' is ' + data[key]);

NSDateComponents

@aymeric answer wont print the numbers in their natural order, but this code will. Explanation at the end.

public class Driver {
    static Object lock = new Object();

    public static void main(String[] args) {
        Thread t1 = new Thread(new Runnable() {
            public void run() {

                for (int itr = 1; itr < 51; itr = itr + 2) {
                    synchronized (lock) {
                        System.out.print(" " + itr);
                        try {
                            lock.notify();
                            lock.wait();
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    }
                }
            }
        });
        Thread t2 = new Thread(new Runnable() {
            public void run() {

                for (int itr = 2; itr < 51; itr = itr + 2) {
                    synchronized (lock) {
                        System.out.print(" " + itr);
                        try {
                            lock.notify();
                            if(itr==50)
                                break;
                            lock.wait();
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    }
                }
            }
        });
        try {
            t1.start();
            t2.start();
            t1.join();
            t2.join();
            System.out.println("\nPrinting over");
        } catch (Exception e) {

        }
    }
}

In order to achieve so, the run methods of the two threads above have to be called one after the other, i.e. they need to be synchronized and I am achieving that using locks.

The code works like this: t1.run prints the odd number and notifies any waiting thread that it is going to release the lock, then goes into a wait state.

At this point t2.run is invoked, it prints the next even number, notifies other threads that it is about to release the lock it holds and then goes into wait state.

This continues till the itr in t2.run() reaches 50, at this point our goal has been achieved and we need to kill these two threads.

By breaking, I avoid calling lock.wait() in t2.run and t2 thread is thus shutdown, the control will now go to t1.run since it was waiting to acquire the lock; but here itr value will be > 51 and we will come out of its run(), thus shutting down the thread.

If break is not used in t2.run(), though we will see numbers 1 to 50 on the screen but the two threads will get into a deadlock situation and continue to be in wait state.

The following shows an example of a shared class library shared.[h,cpp] and a main.cpp module using the library. It's a very simple example and the makefile could be made much better. But it works and may help you:

shared.h defines the class:

class myclass {
   int myx;

  public:

    myclass() { myx=0; }
    void setx(int newx);
    int  getx();
};

shared.cpp defines the getx/setx functions:

#include "shared.h"

void myclass::setx(int newx) { myx = newx; }
int  myclass::getx() { return myx; }

main.cpp uses the class,

#include <iostream>
#include "shared.h"

using namespace std;

int main(int argc, char *argv[])
{
  myclass m;

  cout << m.getx() << endl;
  m.setx(10);
  cout << m.getx() << endl;
}

and the makefile that generates libshared.so and links main with the shared library:

main: libshared.so main.o
    $(CXX) -o main  main.o -L. -lshared

libshared.so: shared.cpp
    $(CXX) -fPIC -c shared.cpp -o shared.o
    $(CXX) -shared  -Wl,-soname,libshared.so -o libshared.so shared.o

clean:
    $rm *.o *.so

To actual run 'main' and link with libshared.so you will probably need to specify the load path (or put it in /usr/local/lib or similar).

The following specifies the current directory as the search path for libraries and runs main (bash syntax):

export LD_LIBRARY_PATH=.
./main

To see that the program is linked with libshared.so you can try ldd:

LD_LIBRARY_PATH=. ldd main

Prints on my machine:

  ~/prj/test/shared$ LD_LIBRARY_PATH=. ldd main
    linux-gate.so.1 =>  (0xb7f88000)
    libshared.so => ./libshared.so (0xb7f85000)
    libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb7e74000)
    libm.so.6 => /lib/libm.so.6 (0xb7e4e000)
    libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0xb7e41000)
    libc.so.6 => /lib/libc.so.6 (0xb7cfa000)
    /lib/ld-linux.so.2 (0xb7f89000)

Try this: B = A ( : ), or try the reshape function.

If, like me, you use Spyder IDE, you have to disable the interactive mode with :

plt.ioff()

(this command is automatically launched with the scientific startup)

If you want to enable it again, use :

plt.ion()

You use the sql%rowcount variable.

You need to call it straight after the statement which you need to find the affected row count for.

For example:

set serveroutput ON; 
DECLARE 
    i NUMBER; 
BEGIN 
    UPDATE employees 
    SET    status = 'fired' 
    WHERE  name LIKE '%Bloggs'; 
    i := SQL%rowcount; 
    --note that assignment has to precede COMMIT
    COMMIT; 
    dbms_output.Put_line(i); 
END; 

Consider creating an index. A dictionary can do the trick. If you need the list semantics, subclass and keep the index as a private member...

I have taken this and various other comments and created a bit more advanced function for running an application and getting the output.

Example to Call Function: Will output the DIR list of C:\ for Directories only. The output will be returned to the variable CommandResults as well as remain in C:\OUTPUT.TXT.

CommandResults = vFn_Sys_Run_CommandOutput("CMD.EXE /C DIR C:\ /AD",1,1,"C:\OUTPUT.TXT",0,1)

Function

Function vFn_Sys_Run_CommandOutput (Command, Wait, Show, OutToFile, DeleteOutput, NoQuotes)
'Run Command similar to the command prompt, for Wait use 1 or 0. Output returned and
'stored in a file.
'Command = The command line instruction you wish to run.
'Wait = 1/0; 1 will wait for the command to finish before continuing.
'Show = 1/0; 1 will show for the command window.
'OutToFile = The file you wish to have the output recorded to.
'DeleteOutput = 1/0; 1 deletes the output file. Output is still returned to variable.
'NoQuotes = 1/0; 1 will skip wrapping the command with quotes, some commands wont work
'                if you wrap them in quotes.

There are four ways of doing so:

• Clean way, reverting but keep in log the revert:

  git revert --strategy resolve <commit>
  

• Harsh way, remove altogether only the last commit:

  git reset --soft "HEAD^"
  

Note: Avoid git reset --hard as it will also discard all changes in files since the last commit. If --soft does not work, rather try --mixed or --keep.

• Rebase (show the log of the last 5 commits and delete the lines you don't want, or reorder, or squash multiple commits in one, or do anything else you want, this is a very versatile tool):

  git rebase -i HEAD~5
  

And if a mistake is made:

git rebase --abort

• Quick rebase: remove only a specific commit using its id:

  git rebase --onto commit-id^ commit-id
  

• Alternatives: you could also try:

  git cherry-pick commit-id
  

• Yet another alternative:

  git revert --no-commit
  

• As a last resort, if you need full freedom of history editing (eg, because git don't allow you to edit what you want to), you can use this very fast open source application: reposurgeon.

Note: of course, all these changes are done locally, you should git push afterwards to apply the changes to the remote. And in case your repo doesn't want to remove the commit ("no fast-forward allowed", which happens when you want to remove a commit you already pushed), you can use git push -f to force push the changes.

Note2: if working on a branch and you need to force push, you should absolutely avoid git push --force because this may overwrite other branches (if you have made changes in them, even if your current checkout is on another branch). Prefer to always specify the remote branch when you force push: git push --force origin your_branch.

Use some external app like sed:

<exec executable="sed" inputstring="${wersja}" outputproperty="wersjaDot">
  <arg value="s/_/./g"/>
</exec>
<echo>${wersjaDot}</echo>

If you run Windows get it googling for "gnuwin32 sed".

The command s/_/./g replaces every _ with . This script goes well under windows. Under linux arg may need quoting.

I had csrf enabled in my sprint security xml file, so I just added one line in the form:

<input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}" /> 

This way I was able to submit the form having the model attribute.

For Single valued associations, i.e.-One-to-One and Many-to-One:-
Default Lazy=proxy
Proxy lazy loading:- This implies a proxy object of your associated entity is loaded. This means that only the id connecting the two entities is loaded for the proxy object of associated entity.
Eg: A and B are two entities with Many to one association. ie: There may be multiple A's for every B. Every object of A will contain a reference of B.
`

public class A{
    int aid;
    //some other A parameters;
    B b;
}
public class B{
    int bid;
     //some other B parameters;
}

`
The relation A will contain columns(aid,bid,...other columns of entity A).
The relation B will contain columns(bid,...other columns of entity B)
Proxy implies when A is fetched, only id is fetched for B and stored into a proxy object of B which contains only id. Proxy object of B is a an object of a proxy-class which is a subclass of B with only minimal fields. Since bid is already part of relation A, it is not necessary to fire a query to get bid from the relation B. Other attributes of entity B are lazily loaded only when a field other than bid is accessed.

For Collections, i.e.-Many-to-Many and One-to-Many:-
Default Lazy=true


Please also note that the fetch strategy(select,join etc) can override lazy. ie: If lazy='true' and fetch='join', fetching of A will also fetch B or Bs(In case of collections). You can get the reason if you think about it.
Default fetch for single valued association is "join".
Default fetch for collections is "select". Please verify the last two lines. I have deduced that logically.

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

static final int COMPARE_EARLIEST = 0;

static final int COMPARE_MOST_RECENT = 1;


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

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

   return refDate;
}

There already exists a function for this:

from operator import itemgetter

my_dict = {x: x**2 for x in range(10)}

itemgetter(1, 3, 2, 5)(my_dict)
#>>> (1, 9, 4, 25)

itemgetter will return a tuple if more than one argument is passed. To pass a list to itemgetter, use

itemgetter(*wanted_keys)(my_dict)

Keep in mind that itemgetter does not wrap its output in a tuple when only one key is requested, and does not support zero keys being requested.

Here is another way to display PDF inside Div by using Iframe like below.

<div>_x000D_
  <iframe src="/pdf/test.pdf" style="width:100%;height:700px;"></iframe>_x000D_
</div>_x000D_
<div>_x000D_
  <!-- I agree button -->_x000D_
</div>

Rather than Runtime.exec(String command), you need to use the exec(String command, String[] envp, File dir) method signature:

Process p =  Runtime.getRuntime().exec("cmd /c upsert.bat", null, new File("C:\\Program Files\\salesforce.com\\Data Loader\\cliq_process\\upsert"));

But personally, I'd use ProcessBuilder instead, which is a little more verbose but much easier to use and debug than Runtime.exec().

ProcessBuilder pb = new ProcessBuilder("cmd", "/c", "upsert.bat");
File dir = new File("C:/Program Files/salesforce.com/Data Loader/cliq_process/upsert");
pb.directory(dir);
Process p = pb.start();

add one folder any name e.g public and add .htaccess file and write allow from all it means, in this folder your all files and all folder will not give error Access forbidden! use it like this

<link href="<?php echo base_url(); ?>application/public/css/style.css" rel="stylesheet" type="text/css"  />
<script type="text/javascript" src="<?php echo base_url(); ?>application/public/js/javascript.js"></script>

private <A, B> Map<B, A> invertMap(Map<A, B> map) {
    Map<B, A> reverseMap = new HashMap<>();
    for (Map.Entry<A, B> entry : map.entrySet()) {
        reverseMap.put(entry.getValue(), entry.getKey());
    }
    return reverseMap;
}

It's important to remember that put replaces the value when called with the same key. So if you map has two keys with the same value only one of them will exist in the inverted map.
