You're storing the .Text properties of the textboxes directly into the database, this doesn't work. The .Text properties are Strings (i.e. simple text) and not typed as DateTime instances. Do the conversion first, then it will work.

Do this for each date parameter:

Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) ) 

Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse or DateTime.TryParseExact, but implementing that is an exercise for the reader.

In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

See here:

• How does Spring @Configuration cache references to beans

being overwhelmed by being VERY NEW to python i missed some very simple and useful commands given here: Print in terminal with colors using Python? -

eventually decided to use CLINT as an answer that was given there by great and smart people

You can prevent from this error by using hooks inside a function

Here is my Timer widget, not related to the Question but may help someone.

import 'dart:async';

import 'package:flutter/material.dart';

class OtpTimer extends StatefulWidget {
  @override
  _OtpTimerState createState() => _OtpTimerState();
}

class _OtpTimerState extends State<OtpTimer> {
  final interval = const Duration(seconds: 1);

  final int timerMaxSeconds = 60;

  int currentSeconds = 0;

  String get timerText =>
      '${((timerMaxSeconds - currentSeconds) ~/ 60).toString().padLeft(2, '0')}: ${((timerMaxSeconds - currentSeconds) % 60).toString().padLeft(2, '0')}';

  startTimeout([int milliseconds]) {
    var duration = interval;
    Timer.periodic(duration, (timer) {
      setState(() {
        print(timer.tick);
        currentSeconds = timer.tick;
        if (timer.tick >= timerMaxSeconds) timer.cancel();
      });
    });
  }

  @override
  void initState() {
    startTimeout();
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Row(
      mainAxisSize: MainAxisSize.min,
      children: <Widget>[
        Icon(Icons.timer),
        SizedBox(
          width: 5,
        ),
        Text(timerText)
      ],
    );
  }
}

You will get something like this

For others who have the same problem in IntelliJ:

upgrading to the latest IDE version should resolve the issue.

In my case going from 2018.1 -> 2018.3.3

Wrap your ListView in an Expanded widget

 Expanded(child:MyListView())

The reason for this error occurs is that you are using the CryptoListPresenter _presenter without initializing.

I found that CryptoListPresenter _presenter would have to be initialized to fix because _presenter.loadCurrencies() is passing through a null variable at the time of instantiation;

there are two ways to initialize

1. Can be initialized during an declaration, like this

   CryptoListPresenter _presenter = CryptoListPresenter();
   

2. In the second, initializing(with assigning some value) it when initState is called, which the framework will call this method once for each state object.

   @override
   void initState() {
     _presenter = CryptoListPresenter(...);
   }
   

The Flexible does the trick

new Container(
       child: Row(
         children: <Widget>[
            Flexible(
               child: new Text("A looooooooooooooooooong text"))
                ],
        ));

This is the official doc https://flutter.dev/docs/development/ui/layout#lay-out-multiple-widgets-vertically-and-horizontally on how to arrange widgets.

Remember that Flexible and also Expanded, should only be used within a Column, Row or Flex, because of the Incorrect use of ParentDataWidget.

The solution is not the mere Flexible

Thanks guys for help. From your suggestions i reached a solution like this.

new LayoutBuilder(
        builder:
            (BuildContext context, BoxConstraints viewportConstraints) {
          return SingleChildScrollView(
            child: ConstrainedBox(
              constraints:
                  BoxConstraints(minHeight: viewportConstraints.maxHeight),
              child: Column(children: [
             // remaining stuffs
              ]),
            ),
          );
        },
      )

Set alignment: Alignment.centerRight in Container:

Container(
    alignment: Alignment.centerRight,
    child:Text(
       "Hello",
    ),
)

Try:

Column(
 mainAxisAlignment: MainAxisAlignment.center,
 crossAxisAlignment: CrossAxisAlignment.center,
 children:children...)

Have a look at this solution I came up with

Positioned( child: SizedBox( child: CircularProgressIndicator(), width: 50, height: 50,), left: MediaQuery.of(context).size.width / 2 - 25);

On your backEnd, you should add:

@RequestMapping(value="/blabla",  produces="text/plain" , method = RequestMethod.GET)

On the frontEnd (Service):

methodBlabla() 
{
  const headers = new HttpHeaders().set('Content-Type', 'text/plain; charset=utf-8');
  return this.http.get(this.url,{ headers, responseType: 'text'});
}

You need to use an Expanded Widget. But, if your button is on a column, the Expanded Widget fills the rest of the column. So, you need to enclose the Expanded Widget within a row.

Row(children: <Widget>[
Expanded(
  flex: 1,
  child: RaisedButton(
    child: Text("Your Text"),
      onPressed: _submitForm,
    ),
  ),),])

This worked for me.

The simplest way to give match-parent width or height in the given code above.

...
width: double.infinity,
height: double.infinity,
...

The following steps work for me:

1. npm cache clean -f
2. rm -rf node_modules
3. npm i

Specify maven.compiler.source and target versions.

1) Maven version which supports jdk you use. In my case JDK 11 and maven 3.6.0.

2) pom.xml

<properties>
    <maven.compiler.source>11</maven.compiler.source>
    <maven.compiler.target>11</maven.compiler.target>
</properties>

As an alternative, you can fully specify maven compiler plugin. See previous answers. It is shorter in my example :)

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.0</version>
            <configuration>
                <release>11</release>
            </configuration>
        </plugin>
    </plugins>
</build>

3) rebuild the project to avoid compile errors in your IDE.

4) If it still does not work. In Intellij Idea I prefer using terminal instead of using terminal from OS. Then in Idea go to file -> settings -> build tools -> maven. I work with maven I downloaded from apache (by default Idea uses bundled maven). Restart Idea then and run mvn clean install again. Also make sure you have correct Path, MAVEN_HOME, JAVA_HOME environment variables.

I also saw this one-liner, but it does not work.

<maven.compiler.release>11</maven.compiler.release>

I made some quick starter projects, which I re-use in other my projects, feel free to check:

• https://github.com/yan-khonski-it/mvn-pmd-java11
• https://github.com/yan-khonski-it/pmd-java-14

I had similar issue and no errors shown in Compilation. I have tried to clean and rebuild without any success. I managed to find the issue by using Invalidate Caches/Restart from file Menu, after the restart I managed to see the compilation error.

Step 1: Create Dialog

   showAlertDialog(BuildContext context){
      AlertDialog alert=AlertDialog(
        content: new Row(
            children: [
               CircularProgressIndicator(),
               Container(margin: EdgeInsets.only(left: 5),child:Text("Loading" )),
            ],),
      );
      showDialog(barrierDismissible: false,
        context:context,
        builder:(BuildContext context){
          return alert;
        },
      );
    }

Step 2:Call it

showAlertDialog(context);
await firebaseAuth.signInWithEmailAndPassword(email: email, password: password);
Navigator.pop(context);

Example With Dialog and login form

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:firebase_auth/firebase_auth.dart';
class DynamicLayout extends StatefulWidget{
  @override
  State<StatefulWidget> createState() {

    return new MyWidget();
    }
  }
showAlertDialog(BuildContext context){
  AlertDialog alert=AlertDialog(
    content: new Row(
        children: [
           CircularProgressIndicator(),
           Container(margin: EdgeInsets.only(left: 5),child:Text("Loading" )),
        ],),
  );
  showDialog(barrierDismissible: false,
    context:context,
    builder:(BuildContext context){
      return alert;
    },
  );
}

  class MyWidget extends State<DynamicLayout>{
  Color color = Colors.indigoAccent;
  String title='app';
  GlobalKey<FormState> globalKey=GlobalKey<FormState>();
  String email,password;
  login() async{
   var currentState= globalKey.currentState;
   if(currentState.validate()){
        currentState.save();
        FirebaseAuth firebaseAuth=FirebaseAuth.instance;
        try {
          showAlertDialog(context);
          AuthResult authResult=await firebaseAuth.signInWithEmailAndPassword(
              email: email, password: password);
          FirebaseUser user=authResult.user;
          Navigator.pop(context);
        }catch(e){
          print(e);
        }
   }else{

   }
  }
  @override
  Widget build(BuildContext context) {
    return new Scaffold(
        appBar:AppBar(
        title: Text("$title"),
        ) ,
          body: Container(child: Form(
            key: globalKey,
            child: Container(
              padding: EdgeInsets.all(10),
              child: Column(children: <Widget>[
              TextFormField(decoration: InputDecoration(icon: Icon(Icons.email),labelText: 'Email'),
              // ignore: missing_return
              validator:(val){
                if(val.isEmpty)
                  return 'Please Enter Your Email';
              },
              onSaved:(val){
                email=val;
              },
              ),
                TextFormField(decoration: InputDecoration(icon: Icon(Icons.lock),labelText: 'Password'),
             obscureText: true,
                  // ignore: missing_return
                  validator:(val){
                    if(val.isEmpty)
                      return 'Please Enter Your Password';
                  },
                  onSaved:(val){
                    password=val;
                  },
              ),
                RaisedButton(color: Colors.lightBlue,textColor: Colors.white,child: Text('Login'),
                  onPressed:login),
            ],)
              ,),)
         ),
    );
  }
}

fsevents is dealt differently in mac and other linux system. Linux system ignores fsevents whereas mac install it. As the above error message states that fsevents is optional and it is skipped in installation process.

You can run npm install --no-optional command in linux system to avoid above warning.

Edit (as suggested in comments and other people), Visual Studio Code has evolved and provides this functionality in-built as the command "Organize imports", with the following default keyboard shortcuts:

option+Shift+O for Mac

Alt + Shift + O for Windows

Original answer:

I hope this visual studio code extension will suffice your need: https://marketplace.visualstudio.com/items?itemName=rbbit.typescript-hero

It provides following features:

• Add imports of your project or libraries to your current file
• Add an import for the current name under the cursor
• Add all missing imports of a file with one command
• Intellisense that suggests symbols and automatically adds the needed imports "Light bulb feature" that fixes code you wrote
• Sort and organize your imports (sort and remove unused)
• Code outline view of your open TS / TSX document
• All the cool stuff for JavaScript as well! (experimental stage though, better description below.)

For Mac: control+option+o

For Win: Ctrl+Alt+o

Try to run

npm i node-sass@latest

Return ABDeadlineType from repository:

public interface ABDeadlineTypeRepository extends JpaRepository<ABDeadlineType, Long> {
    List<ABDeadlineType> findAllSummarizedBy();
}

and then convert to DeadlineType. Manually or use mapstruct.

Or call constructor from @Query annotation:

public interface DeadlineTypeRepository extends JpaRepository<ABDeadlineType, Long> {

    @Query("select new package.DeadlineType(a.id, a.code) from ABDeadlineType a ")
    List<DeadlineType> findAllSummarizedBy();
}

Or use @Projection:

@Projection(name = "deadline", types = { ABDeadlineType.class })
public interface DeadlineType {

    @Value("#{target.id}")
    String getId();

    @Value("#{target.code}")
    String getText();

}

Update: Spring can work without @Projection annotation:

public interface DeadlineType {
    String getId();    
    String getText();
}

You need to enqueue the script bootstrap.js or bootstrap.min.js. I had the same problem with bootstrap 4.5.3 and the menu worked when I enqueued one of the above scripts. It can be either.

It's not fancy I known but you could use a callback class, create a hostbuilder and set the configuration to a static property.

For asp core 2.2:

using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using System;

namespace Project
{
    sealed class Program
    {
        #region Variables
        /// <summary>
        /// Last loaded configuration
        /// </summary>
        private static IConfiguration _Configuration;
        #endregion

        #region Properties
        /// <summary>
        /// Default application configuration
        /// </summary>
        internal static IConfiguration Configuration
        {
            get
            {
                // None configuration yet?
                if (Program._Configuration == null)
                {
                    // Create the builder using a callback class
                    IWebHostBuilder builder = WebHost.CreateDefaultBuilder().UseStartup<CallBackConfiguration>();

                    // Build everything but do not initialize it
                    builder.Build();
                }

                // Current configuration
                return Program._Configuration;
            }

            // Update configuration
            set => Program._Configuration = value;
        }
        #endregion

        #region Public
        /// <summary>
        /// Start the webapp
        /// </summary>
        public static void Main(string[] args)
        {
            // Create the builder using the default Startup class
            IWebHostBuilder builder = WebHost.CreateDefaultBuilder(args).UseStartup<Startup>();

            // Build everything and run it
            using (IWebHost host = builder.Build())
                host.Run();
        }
        #endregion


        #region CallBackConfiguration
        /// <summary>
        /// Aux class to callback configuration
        /// </summary>
        private class CallBackConfiguration
        {
            /// <summary>
            /// Callback with configuration
            /// </summary>
            public CallBackConfiguration(IConfiguration configuration)
            {
                // Update the last configuration
                Program.Configuration = configuration;
            }

            /// <summary>
            /// Do nothing, just for compatibility
            /// </summary>
            public void Configure(IApplicationBuilder app, IHostingEnvironment env)
            {
                //
            }
        }
        #endregion
    }
}

So now on you just use the static Program.Configuration at any other class you need it.

In the AppContext.cs besides AppContext class add another class:

// required when local database deleted
public class ToDoContextFactory : IDesignTimeDbContextFactory<AppContext>
{
    public AppContext CreateDbContext(string[] args)
    {
        var builder = new DbContextOptionsBuilder<AppContext>();
          builder.UseSqlServer("Server=localhost;Database=DbName;Trusted_Connection=True;MultipleActiveResultSets=true");
        return new AppContext(builder.Options);
    }
}

This will solve your second problem:

"Unable to create an object of type 'MyContext'. Add an implementation of 'IDesignTimeDbContextFactory' to the project,

After that you will be able to add-migration Initial and execute it by running update-database command. However if running these commands when there is no DataBase yet in your local SqlServer you will get the warning like your first error: "An error

occurred while calling method 'BuildWebHost' on class 'Program'... The login failed. Login failed for user '...'"

But it is not error because migration will be created and it can be executed. So just ignore this error for the first time, and latter since Db will exist it won't happen again.

When this happened to me it was because my script had DOS line endings, which always messes up the shebang line at the top of the script. I changed it to Unix line endings and it worked.

I have SingleChildScrollView as a parent, and one Column Widget and then List View Widget as last child.

Adding these properties in List View Worked for me.

  physics: NeverScrollableScrollPhysics(),
  shrinkWrap: true,
  scrollDirection: Axis.vertical,

In my case, I had the .eslintrc.json file inside the .vscode folder. Once I moved it out to the root folder, ESLint started working correctly.

I found the solution after a few tries, I hope this can help you. Add the following to your <ReactTable> component:

getTrProps={(state, rowInfo) => {
  if (rowInfo && rowInfo.row) {
    return {
      onClick: (e) => {
        this.setState({
          selected: rowInfo.index
        })
      },
      style: {
        background: rowInfo.index === this.state.selected ? '#00afec' : 'white',
        color: rowInfo.index === this.state.selected ? 'white' : 'black'
      }
    }
  }else{
    return {}
  }
}

In your state don't forget to add a null selected value, like:

state = { selected: null }

Try to use the latest com.fasterxml.jackson.core/jackson-databind. I upgraded it to 2.9.4 and it works now.

Appart from setting maven source url to your gradle, I would suggest to add both design and appcompat libraries. Currently the latest version is 26.1.0

maven {

...

compile 'com.android.support:appcompat-v7:26.1.0'
compile 'com.android.support:design:26.1.0'

This one worked for me.

Similarly, we have a function to set or delete the token from calls like this:

import axios from 'axios';

export default function setAuthToken(token) {
  axios.defaults.headers.common['Authorization'] = '';
  delete axios.defaults.headers.common['Authorization'];

  if (token) {
    axios.defaults.headers.common['Authorization'] = `${token}`;
  }
}

We always clean the existing token at initialization, then establish the received one.

You can run the sleep command before your ExecStart with ExecStartPre :

[Service]
ExecStartPre=/bin/sleep 30

I had this problem before and to fix this, Just make sure :

1. You did not create an instance of this class before
2. If you call this from a class method, make sure the __destruct is set on the class you called from.

My problem (before) :
I had class : Core, Router, Permissions and Render Core include's the Router class, Router then calls Permissions class, then Router __destruct calls the Render class and the error "Cannot declare class because the name is already in use" appeared.

Solution :
I added __destruct on Permission class and the __destruct was empty and it's fixed...

CSS solutions not working properly on touch device

I found that any CSS solutions made the menu stay open on touch devices, they didn't collapse anymore.

So I read the article: https://www.brianshim.com/webtricks/drop-down-menus-on-ios-and-android/ (by Brian Shim)
Very useful! It states that a touch device always first checks the existence of a hover class on an element.

But: by using jQuery .show() you introduce a style attribute (display:block;) that makes the menu open up on first touch. Now the menu has opened without the bootstrap 'show' class. If a user chooses a link from the dropdown menu it works perfectly. But if a user decides to close the menu without using it he has to tap twice to close the menu: At the first tap the original bootstrap 'show' class gets attached so the menu opens up again, at the second tap the menu closes due to normal bootstrap behaviour (removal of 'show' class).

To prevent this I used the article: https://codeburst.io/the-only-way-to-detect-touch-with-javascript-7791a3346685 (by David Gilbertson)

He has some very handy ways of detecting touch or hover devices.

So, combined the two authors with a bit jQuery of my own:

$(window).one('mouseover', function(){
      window.USER_CAN_HOVER = true;
      if(USER_CAN_HOVER){
          jQuery('#navbarNavDropdown ul li.dropdown').on("mouseover", function() {
             var $parent = jQuery(this);
             var $dropdown = $parent.children('ul');

             $dropdown.show(200,function() { 
               $parent.mouseleave(function() {
                 var $this = jQuery(this);
                 $this.children('ul').fadeOut(200);
               });
             });
          });
      };

}); Check once if a device allows a hover event. If it does, introduce the possibility to hover using .show(). If the device doesn't allow a hover event, the .show() never gets introduced so you get natural bootstrap behaviour on touch device.

Be sure to remove any CSS regarding menu hover classes.

Took me three days :) so I hope it helps some of you.

You have to use now the new XLSX-Driver from Access-Redist (32/64-Bit). The current XLS-Driver are corrupted since last cumulative update.

In Bootstrap 4 alpha-6 version, As navbar is using flex model, you can use justify-content-end in parent's div and remove mr-auto.

<div class="collapse navbar-collapse justify-content-end" id="navbarText">
  <ul class="navbar-nav">
    <li class="nav-item active">
      <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="#">Link</a>
    </li>
    <li class="nav-item">
      <a class="nav-link disabled" href="#">Disabled</a>
    </li>
  </ul>
</div>

This works like a charm :)

Swift 5
let desiredIndex: Int = 7 let substring = str[String.Index(encodedOffset: desiredIndex)...]
This substring variable will give you the result.
Simply here Int is converted to Index and then you can split the strings. Unless you will get errors.

func change(string: inout String) {

    var character: Character = .normal

    enum Character {
        case space
        case newLine
        case normal
    }

    for i in stride(from: string.count - 1, through: 0, by: -1) {
        // first get index
        let index: String.Index?
        if i != 0 {
            index = string.index(after: string.index(string.startIndex, offsetBy: i - 1))
        } else {
            index = string.startIndex
        }

        if string[index!] == "\n" {

            if character != .normal {

                if character == .newLine {
                    string.remove(at: index!)
                } else if character == .space {
                    let number = string.index(after: string.index(string.startIndex, offsetBy: i))
                    if string[number] == " " {
                        string.remove(at: number)
                    }
                    character = .newLine
                }

            } else {
                character = .newLine
            }

        } else if string[index!] == " " {

            if character != .normal {

                string.remove(at: index!)

            } else {
                character = .space
            }

        } else {

            character = .normal

        }

    }

    // startIndex
    guard string.count > 0 else { return }
    if string[string.startIndex] == "\n" || string[string.startIndex] == " " {
        string.remove(at: string.startIndex)
    }

    // endIndex - here is a little more complicated!
    guard string.count > 0 else { return }
    let index = string.index(before: string.endIndex)
    if string[index] == "\n" || string[index] == " " {
        string.remove(at: index)
    }

}

solved this problem in the /app/app.module.ts file

import your component and declare it

import { MyComponent } from './home-about-me/my.component';

@NgModule({
  declarations: [
    MyComponent,
  ]

In my case, I was updating the server-sided datatable twice and it gives me this error. Hope it helps someone.

That's correct, your response is an object with fields:

{
    "page": 1,
    "results": [ ... ]
}

So you in fact want to iterate the results field only:

this.data = res.json()['results'];

... or even easier:

this.data = res.json().results;

Most of us face this problem for the first time, when we start react native project#1.

Few simple steps solved my problem:

I created a sample project using command:

react-native init ReactProject1

Solution

The fix is to help local-cli\runAndroid\adb.js to find adb.exe, the same way as local-cli\runAndroid\runAndroid.js:

find replace statement under projectname(whatever you have given)\node_modules\react-native\local-cli\runAndroid

Replace:

const devicesResult = child_process.execSync('adb devices');

By:

const devicesResult = child_process.execSync( (process.env.ANDROID_HOME ? process.env.ANDROID_HOME + '/platform-tools/' : '') + 'adb devices');

after doing above replacement, just run react-native run-android in your cmd, it will bundle apk and at first try to install js bundle locally in your device. (Got Success)

If for a some reason can't use rsyslog, this will do: ExecStart=/bin/bash -ce "exec /usr/local/bin/binary1 agent -config-dir /etc/sample.d/server >> /var/log/agent.log 2>&1"

What about this:

with open("your_csv_file.csv", "w") as f:
    f.write("\n".join(text))

str.join() Return a string which is the concatenation of the strings in iterable. The separator between elements is the string providing this method.

Use sortedWith to sort a list with Comparator.

You can then construct a comparator using several ways:

• compareBy, thenBy construct the comparator in a chain of calls:

  list.sortedWith(compareBy<Person> { it.age }.thenBy { it.name }.thenBy { it.address })
  

• compareBy has an overload which takes multiple functions:

  list.sortedWith(compareBy({ it.age }, { it.name }, { it.address }))
  

Change the version number to 2.19.1 works for me :)

`<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.19.1</version>
    <configuration>
        <systemPropertyVariables>
            <xmlOutputDir>${project.build.directory}/surefire</xmlOutputDir>
        </systemPropertyVariables>
    </configuration>
</plugin>`

Cause: The error occurred since hibernate is not able to connect to the database.
Solution:
1. Please ensure that you have a database present at the server referred to in the configuration file eg. "hibernatedb" in this case.
2. Please see if the username and password for connecting to the db are correct.
3. Check if relevant jars required for the connection are mapped to the project.

Including more than one reference to Jquery library is the reason for the error Only Include one reference to the Jquery library and that will resolve the issue

A slight modification beyond @udondan's answer. I like to reuse the registered variable names with the set_fact to help keep the clutter to a minimum.

So if I were to register using the variable, psk, I'd use that same variable name with creating the set_fact.

Example

- name: generate PSK
  shell: openssl rand -base64 48
  register: psk
  delegate_to: 127.0.0.1
  run_once: true

- set_fact: 
    psk={{ psk.stdout }}

- debug: var=psk
  run_once: true

Then when I run it:

$ ansible-playbook -i inventory setup_ipsec.yml

On top of mentioning your environment variable for HADOOP_HOME in windows as C:\winutils, you also need to make sure you are the administrator of the machine. If not and adding environment variables prompts you for admin credentials (even under USER variables) then these variables will be applicable once you start your command prompt as administrator.

If you're just playing around in local mode, you can drop metastore DB and reinstate it:

rm -rf metastore_db/

If you are using babel, you should check out babel-plugin-lodash, it will cherry-pick the parts of lodash you are using for you, less hassle and a smaller bundle.

It has a few limitations:

• You must use ES2015 imports to load Lodash
• Babel < 6 & Node.js < 4 aren’t supported
• Chain sequences aren’t supported. See this blog post for alternatives.
• Modularized method packages aren’t supported

I don't know about all the lifecycle hooks, but as for destruction, ngOnDestroy actually get called on Injectable when it's provider is destroyed (for example an Injectable supplied by a component).

From the docs :

Lifecycle hook that is called when a directive, pipe or service is destroyed.

Just in case anyone is interested in destruction check this question:

You have a numpy array of strings, not floats. This is what is meant by dtype('<U9') -- a little endian encoded unicode string with up to 9 characters.

try:

return sum(np.asarray(listOfEmb, dtype=float)) / float(len(listOfEmb))

However, you don't need numpy here at all. You can really just do:

return sum(float(embedding) for embedding in listOfEmb) / len(listOfEmb)

Or if you're really set on using numpy.

return np.asarray(listOfEmb, dtype=float).mean()

Don't get surprised by the list of answers for a single question. There are various causes for this issue;

For my case, the warning was

warning.js:33 Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in. Check your code at index.js:13.

Followed by the error

invariant.js:42 Uncaught Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in.

I couldn't understand the error since it doesn't mention any method or file name. I was able to resolve only after looking at this warning, mentioned above.

I have the following line at the index.js.

<ConnectedRouter history={history}>

When I googled for the above error with the keyword "ConnectedRouter" I found the solution in a GitHub page.

The error is because, when we install react-router-redux package, by default we install this one. https://github.com/reactjs/react-router-redux but not the actual library.

To resolve this error, install the proper package by specifing the npm scope with @

npm install react-router-redux@next

You don't need to remove the wrongly installed package. It will be automatically overwritten.

Thank you.

PS: Even warning helps you. Don't neglect warning just looking at the error alone.

I tried to connect sql server in following ways and those worked for me.

To connect using windows authentication

import pyodbc

conn = pyodbc.connect('Driver={SQL Server};Server='+servername+';Trusted_Connection=yes;Database='+databasename+';')
cursor = conn.cursor()
cursor.execute("Select 1 as Data")

To use sql server authentication I used following code.

import pyodbc

conn = pyodbc.connect('Driver={SQL Server};Server='+servername+  ';UID='+userid+';PWD='+password+';Database='+databasename) 
cursor1 = conn.cursor()
cursor1.execute("SELECT 1 AS DATA")

If you do not want to use jQuery, make the button type a normal button and add a click listener pointing to the function you would like to execute, and send the form in as a parameter. The button would be as follows:

<button (click)="yourSubmitFunction(yourForm)" [disabled]="!yourForm.valid" type="button" class="btn btn-primary" data-dismiss="modal">Save changes</button>

Remember to remove: (ngSubmit)="yourSubmitFunction(yourForm)" from the form div if you use this method.

//Calling     
[self showMessage:@"There is no internet connection for this device"
                    withTitle:@"Error"];

//Method

-(void)showMessage:(NSString*)message withTitle:(NSString *)title
{

 UIAlertController * alert=   [UIAlertController
                                  alertControllerWithTitle:title
                                  message:message
                                  preferredStyle:UIAlertControllerStyleAlert];

    UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){

        //do something when click button
    }];
    [alert addAction:okAction];
    UIViewController *vc = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
    [vc presentViewController:alert animated:YES completion:nil];
}

If you want to use this alert in NSObject class you should use like:

-(void)showMessage:(NSString*)message withTitle:(NSString *)title{
dispatch_async(dispatch_get_main_queue(), ^{
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];
    [alertController addAction:[UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

    }]];

    [[[[UIApplication sharedApplication] keyWindow] rootViewController] presentViewController:alertController animated:YES completion:^{
    }];
});
}

Laravel optional() Helper is comes to solve this problem. Try this helper so that if any key have not value then it not return error

      $sample_data[] = array(       
        'client_phone' =>optional($users)->phone        
      );
    }
 print_r($sample_data);

Beyond removing .m2/repository, remove application from server, run server (without applications), stop it and add application again. Now it is supposed to work. For some reason just cleaning up server folders from interface doesn't have the same effect.

You are opening an asynchronous connection, yet you have written your code as if it was synchronous. The reqListener callback function will not execute synchronously with your code (that is, before React.createClass), but only after your entire snippet has run, and the response has been received from your remote location.

Unless you are on a zero-latency quantum-entanglement connection, this is well after all your statements have run. For example, to log the received data, you would:

function reqListener(e) {
    data = JSON.parse(this.responseText);
    console.log(data);
}

I'm not seeing the use of data in the React component, so I can only suggest this theoretically: why not update your component in the callback?

You can also write a little wrapper function like this

const onEnter = (event, callback) => event.key === 'Enter' && callback()

Then consume it on your inputs

<input 
    type="text" 
    placeholder="Title of todo" 
    onChange={e => setName(e.target.value)}
    onKeyPress={e => onEnter(e, addItem)}/>

Using NewRequest just to create an URL is an overkill. Use the net/url package:

package main

import (
    "fmt"
    "net/url"
)

func main() {
    base, err := url.Parse("http://www.example.com")
    if err != nil {
        return
    }

    // Path params
    base.Path += "this will get automatically encoded"

    // Query params
    params := url.Values{}
    params.Add("q", "this will get encoded as well")
    base.RawQuery = params.Encode() 

    fmt.Printf("Encoded URL is %q\n", base.String())
}

Think to change JDK used in your project. For me I changed JDK from 1.6 to 1.8 and I updated maven.

On Windows: if you use %>% inside a %dopar% loop, you have to add a reference to load package dplyr (or magrittr, which dplyr loads).

Example:

plots <- foreach(myInput=iterators::iter(plotCount), .packages=c("RODBC", "dplyr")) %dopar%
{
    return(getPlot(myInput))
}

If you omit the .packages command, and use %do% instead to make it all run in a single process, then works fine. The reason is that it all runs in one process, so it doesn't need to specifically load new packages.

I think it is jar file version problem. I had the same issue and I fixed it by changing the commons-codec-1.6.jar file from the build path. Earlier I was using latest version 1.10. Gradually I decreased the versions and 1.6 version fixed my issue.

I had the similar prolem with OP. As the terminal output suggested, I went to http://wiki.apache.org/hadoop/ConnectionRefused

I tried to change my /etc/hosts file as suggested here, i.e. remove 127.0.1.1 as OP suggested it will create another error.

So in the end, I leave it as is. The following is my /etc/hosts

127.0.0.1       localhost.localdomain   localhost
127.0.1.1       linux
# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

In the end, I found that my namenode did not started correctly, i.e. When you type sudo netstat -lpten | grep java in the terminal, there will not be any JVM process running(listening) on port 9000.

So I made two directories for namenode and datanode respectively(if you have not done so). You don't have to put where I put it, please replace it based on your hadoop directory. i.e.

mkdir -p /home/hadoopuser/hadoop-2.6.2/hdfs/namenode
mkdir -p /home/hadoopuser/hadoop-2.6.2/hdfs/datanode

I reconfigured my hdfs-site.xml.

<configuration>
    <property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
   <property>
        <name>dfs.namenode.name.dir</name>
        <value>file:/home/hadoopuser/hadoop-2.6.2/hdfs/namenode</value>
    </property>
    <property>
        <name>dfs.datanode.data.dir</name>
        <value>file:/home/hadoopuser/hadoop-2.6.2/hdfs/datanode</value>
    </property>
</configuration>

In terminal, stop your hdfs and yarn with script stop-dfs.sh and stop-yarn.sh. They are located in your hadoop directory/sbin. In my case, it's /home/hadoopuser/hadoop-2.6.2/sbin/.

Then start your hdfs and yarn with script start-dfs.sh and start-yarn.sh After it is started, type jps in your terminal to see if your JVM processes are running correctly. It should show the following.

15678 NodeManager
14982 NameNode
15347 SecondaryNameNode
23814 Jps
15119 DataNode
15548 ResourceManager

Then try to use netstat again to see if your namenode is listening to port 9000

sudo netstat -lpten | grep java

If you successfully set up the namenode, you should see the following in your terminal output.

tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 1001 175157 14982/java

Then try to type the command hdfs dfs -mkdir /user/hadoopuser If this command executes sucessfully, now you can list your directory in the HDFS user directory by hdfs dfs -ls /user

cors unblock works great for chrome 78 [COrs unb] [1] https://chrome.google.com/webstore/detail/cors-unblock/lfhmikememgdcahcdlaciloancbhjino

it's a plugin for google chrome called "cors unblock"

Summary: No more CORS error by appending 'Access-Control-Allow-Origin: *' header to local and remote web requests when enabled

This extension provides control over XMLHttpRequest and fetch methods by providing custom "access-control-allow-origin" and "access-control-allow-methods" headers to every requests that the browser receives. A user can toggle the extension on and off from the toolbar button. To modify how these headers are altered, use the right-click context menu items. You can customize what method are allowed. The default option is to allow 'GET', 'PUT', 'POST', 'DELETE', 'HEAD', 'OPTIONS', 'PATCH' methods. You can also ask the extension not to overwrite these headers when the server already fills them.

check ur WebApiConfig and add this

GlobalConfiguration.Configuration.Formatters.XmlFormatter.SupportedMediaTypes.Clear();

Yes even I got the same error. So I did the following changes

-> Check the error in the Problems tab located near the Console tab

-> See where the error persists, Its possible that some jar file may be corrupted or is outdated so, pom isn't activated in the Project.

-> I found one of my jar was outdated version so I updated it by getting the dependencies from maven repository from this link https://mvnrepository.com

So to conclude, do check where the error persist and which jar file is outdated and make changes accordingly

I found the problem. This code was placed in a separate file that was added with a php include() function. And this include was happening before the Bootstrap files were loaded. So the Bootstrap JS file was not loaded yet, causing this modal to not do anything.

With the above code sample is nothing wrong and works as intended when placed in the body part of a html page.

<script type="text/javascript">
$('#memberModal').modal('show');
</script>

change below line of code

spring.datasource.driverClassName

to

spring.datasource.driver-class-name

dangerouslySetInnerHTML should not be used unless absolutely necessary. According to the docs, "This is mainly for cooperating with DOM string manipulation libraries". When you use it, you're giving up the benefit of React's DOM management.

In your case, it is pretty straightforward to convert to valid JSX syntax; just change class attributes to className. Or, as mentioned in the comments above, you can use the ReactBootstrap library which encapsulates Bootstrap elements into React components.

Go at References in visual studio and look at which packages are missing. Now right click on Solution in Visual and click on open folder in file explorer. Now open packages folder and delete missing packages folder. Open visual studio and just build the solution. all the missing packages will be restore. Please mark this as answer if I helped.

If you don't care about this question being specifically about a tableview, and you'd just like to center one view on top of another view here's to do it:

    let horizontalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutAttribute.CenterX, relatedBy: NSLayoutRelation.Equal, toItem: parentView, attribute: NSLayoutAttribute.CenterX, multiplier: 1, constant: 0)
    parentView.addConstraint(horizontalConstraint)

    let verticalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutAttribute.CenterY, relatedBy: NSLayoutRelation.Equal, toItem: parentView, attribute: NSLayoutAttribute.CenterY, multiplier: 1, constant: 0)
    parentView.addConstraint(verticalConstraint)

Below is code that I currently use to pull data from a MS SQL Server 2008 into VBA. You need to make sure you have the proper ADODB reference [VBA Editor->Tools->References] and make sure you have Microsoft ActiveX Data Objects 2.8 Library checked, which is the second from the bottom row that is checked (I'm using Excel 2010 on Windows 7; you might have a slightly different ActiveX version, but it will still begin with Microsoft ActiveX):

Sub Module for Connecting to MS SQL with Remote Host & Username/Password

Sub Download_Standard_BOM()
'Initializes variables
Dim cnn As New ADODB.Connection
Dim rst As New ADODB.Recordset
Dim ConnectionString As String
Dim StrQuery As String

'Setup the connection string for accessing MS SQL database
   'Make sure to change:
       '1: PASSWORD
       '2: USERNAME
       '3: REMOTE_IP_ADDRESS
       '4: DATABASE
    ConnectionString = "Provider=SQLOLEDB.1;Password=PASSWORD;Persist Security Info=True;User ID=USERNAME;Data Source=REMOTE_IP_ADDRESS;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Use Encryption for Data=False;Tag with column collation when possible=False;Initial Catalog=DATABASE"

    'Opens connection to the database
    cnn.Open ConnectionString
    'Timeout error in seconds for executing the entire query; this will run for 15 minutes before VBA timesout, but your database might timeout before this value
    cnn.CommandTimeout = 900

    'This is your actual MS SQL query that you need to run; you should check this query first using a more robust SQL editor (such as HeidiSQL) to ensure your query is valid
    StrQuery = "SELECT TOP 10 * FROM tbl_table"

    'Performs the actual query
    rst.Open StrQuery, cnn
    'Dumps all the results from the StrQuery into cell A2 of the first sheet in the active workbook

Integrating SearchView with RecyclerView

1) Add SearchView Item in Menu

SearchView can be added as actionView in menu using

app:useActionClass = "android.support.v7.widget.SearchView" .

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="rohksin.com.searchviewdemo.MainActivity">
<item
    android:id="@+id/searchBar"
    app:showAsAction="always"
    app:actionViewClass="android.support.v7.widget.SearchView"
    />
</menu>

2) Implement SearchView.OnQueryTextListener in your Activity

SearchView.OnQueryTextListener has two abstract methods. So your activity skeleton would now look like this after implementing SearchView text listener.

YourActivity extends AppCompatActivity implements SearchView.OnQueryTextListener{

   public boolean onQueryTextSubmit(String query)

   public boolean onQueryTextChange(String newText) 

}

3) Set up SerchView Hint text, listener etc

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);

    MenuItem searchItem = menu.findItem(R.id.searchBar);

    SearchView searchView = (SearchView) searchItem.getActionView();
    searchView.setQueryHint("Search People");
    searchView.setOnQueryTextListener(this);
    searchView.setIconified(false);

    return true;
}

4) Implement SearchView.OnQueryTextListener

This is how you can implement abstract methods of the listener.

@Override
public boolean onQueryTextSubmit(String query) {

    // This method can be used when a query is submitted eg. creating search history using SQLite DB

    Toast.makeText(this, "Query Inserted", Toast.LENGTH_SHORT).show();
    return true;
}

@Override
public boolean onQueryTextChange(String newText) {

    adapter.filter(newText);
    return true;
}

5) Write a filter method in your RecyclerView Adapter.

You can come up with your own logic based on your requirement. Here is the sample code snippet to show the list of Name which contains the text typed in the SearchView.

public void filter(String queryText)
{
    list.clear();

    if(queryText.isEmpty())
    {
        list.addAll(copyList);
    }
    else
    {

        for(String name: copyList)
        {
            if(name.toLowerCase().contains(queryText.toLowerCase()))
            {
                list.add(name);
            }
        }

    }

    notifyDataSetChanged();
}

Full working code sample can be found > HERE
You can also check out the code on SearchView with an SQLite database in this Music App

You can groupby the 'name' and 'month' columns, then call transform which will return data aligned to the original df and apply a lambda where we join the text entries:

In [119]:

df['text'] = df[['name','text','month']].groupby(['name','month'])['text'].transform(lambda x: ','.join(x))
df[['name','text','month']].drop_duplicates()
Out[119]:
    name         text  month
0  name1       hej,du     11
2  name1        aj,oj     12
4  name2     fin,katt     11
6  name2  mycket,lite     12

I sub the original df by passing a list of the columns of interest df[['name','text','month']] here and then call drop_duplicates

EDIT actually I can just call apply and then reset_index:

In [124]:

df.groupby(['name','month'])['text'].apply(lambda x: ','.join(x)).reset_index()

Out[124]:
    name  month         text
0  name1     11       hej,du
1  name1     12        aj,oj
2  name2     11     fin,katt
3  name2     12  mycket,lite

update

the lambda is unnecessary here:

In[38]:
df.groupby(['name','month'])['text'].apply(','.join).reset_index()

Out[38]: 
    name  month         text
0  name1     11           du
1  name1     12        aj,oj
2  name2     11     fin,katt
3  name2     12  mycket,lite

CryptoSwift Example

Updated to Swift 2

import Foundation
import CryptoSwift

extension String {
    func aesEncrypt(key: String, iv: String) throws -> String{
        let data = self.dataUsingEncoding(NSUTF8StringEncoding)
        let enc = try AES(key: key, iv: iv, blockMode:.CBC).encrypt(data!.arrayOfBytes(), padding: PKCS7())
        let encData = NSData(bytes: enc, length: Int(enc.count))
        let base64String: String = encData.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0));
        let result = String(base64String)
        return result
    }

    func aesDecrypt(key: String, iv: String) throws -> String {
        let data = NSData(base64EncodedString: self, options: NSDataBase64DecodingOptions(rawValue: 0))
        let dec = try AES(key: key, iv: iv, blockMode:.CBC).decrypt(data!.arrayOfBytes(), padding: PKCS7())
        let decData = NSData(bytes: dec, length: Int(dec.count))
        let result = NSString(data: decData, encoding: NSUTF8StringEncoding)
        return String(result!)
    }
}

Usage:

let key = "bbC2H19lkVbQDfakxcrtNMQdd0FloLyw" // length == 32
let iv = "gqLOHUioQ0QjhuvI" // length == 16
let s = "string to encrypt"
let enc = try! s.aesEncrypt(key, iv: iv)
let dec = try! enc.aesDecrypt(key, iv: iv)
print(s) // string to encrypt
print("enc:\(enc)") // 2r0+KirTTegQfF4wI8rws0LuV8h82rHyyYz7xBpXIpM=
print("dec:\(dec)") // string to encrypt
print("\(s == dec)") // true

Make sure you have the right length of iv (16) and key (32) then you won't hit "Block size and Initialization Vector must be the same length!" error.

There is a little known feature in TypeScript that allows you to use Mixins to create re-usable small objects. You can compose these into larger objects using multiple inheritance (multiple inheritance is not allowed for classes, but it is allowed for mixins - which are like interfaces with an associated implenentation).

More information on TypeScript Mixins

I think you could use this technique to share common components between many classes in your game and to re-use many of these components from a single class in your game:

Here is a quick Mixins demo... first, the flavours that you want to mix:

class CanEat {
    public eat() {
        alert('Munch Munch.');
    }
}

class CanSleep {
    sleep() {
        alert('Zzzzzzz.');
    }
}

Then the magic method for Mixin creation (you only need this once somewhere in your program...)

function applyMixins(derivedCtor: any, baseCtors: any[]) {
    baseCtors.forEach(baseCtor => {
        Object.getOwnPropertyNames(baseCtor.prototype).forEach(name => {
             if (name !== 'constructor') {
                derivedCtor.prototype[name] = baseCtor.prototype[name];
            }
        });
    }); 
}

And then you can create classes with multiple inheritance from mixin flavours:

class Being implements CanEat, CanSleep {
        eat: () => void;
        sleep: () => void;
}
applyMixins (Being, [CanEat, CanSleep]);

Note that there is no actual implementation in this class - just enough to make it pass the requirements of the "interfaces". But when we use this class - it all works.

var being = new Being();

// Zzzzzzz...
being.sleep();

UITableViewCell has an attribute multipleSelectionBackgroundView. https://developer.apple.com/documentation/uikit/uitableviewcell/1623226-selectedbackgroundview

Just create an UIView define the .backgroundColor of your choice and assign it to your cells .multipleSelectionBackgroundView attribute.

In my case I had to rename the table with name user. I renamed it for example users and it worked.

(function(){
        $(".modal").on("hidden.bs.modal", function(){
            $(this).removeData();
        });
});

This is perfect solution to remove contact while hide/close bootstrap modal.

I add custom commands to a environment evoked in a CMD after starting services... I haven't done it with postgres, but with Oracle:

#set up var with noop command
RUN export POST_START_CMDS=":"
RUN mkdir /scripts
ADD script.sql /scripts
CMD service oracle-xe start; $POST_START_CMDS; tail -f /var/log/dmesg

and start with

docker run -d ... -e POST_START_CMDS="su - oracle -c 'sqlplus @/scripts/script' " <image>

.

Yes there is, you can simply put <hr> in your code where you want it, I already use it in one of my admin panel side bar.

The easiest solution is to use Uri.getLastPathSegment():

String filename = uri.getLastPathSegment();

• Achartengine: I have used this. Although for real time graph this might not give good performance if you do not tweak properly.

Same case (no DB and MigrationHistory table on Server). My steps:

1. I deleted Migration data from Up and Down section of my first migration.
2. Update Database with empty migration (MigrationHistory table was created)
3. Add your REAL migration and update database with it.

This could be a issue in mvn home path in IntellijIdea IDE. For me it worked out when I set the mvn home directory correctly.

Removing Read-only CheckBox from C:\Users\SQL Service account name\AppData\Local\Temp worked for me.

Auto layout is realized by applying constraints on images. Use NSLayoutConstraint. It is possible to implement an ideal and beautiful design on all devices. Please try the code below.

import UIKit

class ViewController: UIViewController {

override func viewDidLoad() {
super.viewDidLoad()

let myImageView:UIImageView = UIImageView()
myImageView.backgroundColor = UIColor.red
myImageView.image = UIImage(named:"sample_dog")!
myImageView.translatesAutoresizingMaskIntoConstraints = false
myImageView.layer.borderColor = UIColor.red.cgColor
myImageView.layer.borderWidth = 10
self.view.addSubview(myImageView)
        
view.removeConstraints(view.constraints)


view.addConstraint(NSLayoutConstraint(
item: myImageView,
attribute: .top,
relatedBy: .equal,
toItem: view,
attribute: .top,
multiplier: 1,
constant:100)
    
)

view.addConstraint(NSLayoutConstraint(
item: myImageView,
attribute: .centerX,
relatedBy: .equal,
toItem: view,
attribute: .centerX,
multiplier: 1,
constant:0)
)
    
view.addConstraint(NSLayoutConstraint(
item: myImageView,
attribute: .height,
relatedBy: .equal,
toItem: view,
attribute: .width,
multiplier: 0.5,
constant:40))
    
view.addConstraint(NSLayoutConstraint(
item: myImageView,
attribute: .width,
relatedBy: .equal,
toItem: view,
attribute: .width,
multiplier: 0.5,
constant:40))
    
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}
}

What worked for me is setting the height to 100% the having the overflow on auto hope this will help

   <div style="height: 100%;overflow-y: auto;"> Some text o othre div scroll </div>

Always have handy the un-minified CSS for bootstrap so you can see what styles they have on their components, then create a CSS file AFTER it, if you don't use LESS and over-write their mixins or whatever

This is the default modal css for 768px and up:

@media (min-width: 768px) {
  .modal-dialog {
    width: 600px;
    margin: 30px auto;
  }
  ...
}

They have a class modal-lg for larger widths

@media (min-width: 992px) {
  .modal-lg {
    width: 900px;
  }
}

If you need something twice the 600px size, and something fluid, do something like this in your CSS after the Bootstrap css and assign that class to the modal-dialog.

@media (min-width: 768px) {
  .modal-xl {
    width: 90%;
   max-width:1200px;
  }
}

HTML

<div class="modal-dialog modal-xl">

I have created a directive in agularJS supported with ng-bootStrap components

https://angular-ui.github.io/bootstrap/#!#tabs

This warning may also be shown if jQuery is declared more than once in your code. The second jQuery declaration prevents bootstrap.js from working correctly.

<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>

Not really a technical solution, but SQL Server 2017 flat file import is totally revamped, and imported my large-ish file with 5 clicks, handled encoding / field length issues without any input from me

You can define an interface with an indexer:

interface EnumServiceGetOrderBy {
    [index: number]: { id: number; label: string; key: any };
}

This worked for me:

$ sudo apt-get install php-gd php-mysql

I had a similar problem running SciPy on my computer. There are two ways to fix this problem: 1. Yes you do need to cd into your python directory. 2. Sometimes you have to tell the computer explicitly what path to go through, you have to find the program you're using, open up the properties, and reroute the path it takes to run. 3. consult the manual: http://matplotlib.org/users/installing.html or http://www.scipy.org/install.html

the Scipy package is very finicky, and needs things spelled out in obnoxious detail.

I've the same problem right now. check if you fix fetch in lazy with a @jsonIQgnore

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name="teachers")
@JsonIgnoreProperties("course")
Teacher teach;

Just delete the "(fetch=...)" or the annotation "@jsonIgnore" and it will work

@ManyToOne
@JoinColumn(name="teachers")
@JsonIgnoreProperties("course")
Teacher teach;

In my case I removed the server logon credentials for central from my setting.

    <server> 
        <id>central</id>
        <username>admin</username> 
        <password>******</password> 
    </server>

   <mirror>
        <id>central</id>
        <mirrorOf>central</mirrorOf>
        <name>maven-central</name>
        <url>http://www.localhost:8081/repository/maven-central/</url>
   </mirror> 

I don't know why I did that, but its completely wrong since the central maven repo can be accessed anonymously. See my debug output that led to my error identification and resolution.

[DEBUG] Using connector BasicRepositoryConnector with priority 0.0 for http://www.localhost:8081/repository/maven-central/ with username=admin, password=***

Closures can be declared as typealias as below

typealias Completion = (Bool, Any, Error) -> Void

If you want to use in your function anywhere in code; you can write like normal variable

func xyz(with param1: String, completion: Completion) {
}

I had the same problem. I fixed it by adding this piece of code inside the text area's style.

resize: vertical;

According to me, Spring doesn't handle all the cases with ease. In your case the following should do the trick

Page<QueuedBook> findByBookIdRegion(Region region, Pageable pageable);  

or

Page<QueuedBook> findByBookId_Region(Region region, Pageable pageable);

However, it also depends on the naming convention of fields that you have in your @Embeddable class,

e.g. the following field might not work in any of the styles that mentioned above

private String cRcdDel;

I tried with both the cases (as follows) and it didn't work (it seems like Spring doesn't handle this type of naming conventions(i.e. to many Caps , especially in the beginning - 2nd letter (not sure about if this is the only case though)

Page<QueuedBook> findByBookIdCRcdDel(String cRcdDel, Pageable pageable); 

or

Page<QueuedBook> findByBookIdCRcdDel(String cRcdDel, Pageable pageable);

When I renamed column to

private String rcdDel;

my following solutions work fine without any issue:

Page<QueuedBook> findByBookIdRcdDel(String rcdDel, Pageable pageable); 

OR

Page<QueuedBook> findByBookIdRcdDel(String rcdDel, Pageable pageable);

In my situation, the Oracle 11.2 32-bit client was installed on my 64-bit Windows 2008 R2 OS.

My solution: In the Advanced Settings for the Application Pool assigned to my ASP.NET application, I set Enable 32-Bit Applications to True.

Please see below for the standalone .ashx test script that I used to test the ability to connect to Oracle. Before making the Application Pool change, its response was:

[Running as 64-bit] Connection failed.

...and after the Application Pool change:

[Running as 32-bit] Connection succeeded.

            "[Running as 64-bit]" : "[Running as 32-bit]";

        try
        {
            string connString = String.Format(
              "Data Source={0};Password={1};User ID={2};",
              m_Host, m_User, m_Password);

            OracleConnection oradb = new OracleConnection();
            oradb.ConnectionString = connString;
            oradb.Open();
            oradb.Close();
            result += " Connection succeeded.";
        }
        catch
        {
            result += " Connection failed.";
        }

        return result;
    }
}

Another option is to run the package in 32 bit mode. Click on the solution => properties =? Debugging => Set run in 64 bit to false.

Give an ID to uniquely identify the button, lets say myBtn

// when DOM is ready
$(document).ready(function () {

     // Attach Button click event listener 
    $("#myBtn").click(function(){

         // show Modal
         $('#myModal').modal('show');
    });
});

JSFIDDLE

From the docs:

Modals have two optional sizes, available via modifier classes to be placed on a .modal-dialog: modal-lg and modal-sm (as of 3.1).

Also the modal dialogue will scale itself on small screens (as of 3.1.1).

In my case it was permissions issue. The catch is that on device with Android 4.0.4 I got access to file without any error or exception. And on device with Android 5.1 it failed with ACCESS exception (open failed: EACCES (Permission denied)). Handled it with adding follow permission to manifest file:

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

So I guess that it's the difference between permissions management in OS versions that causes to failures.

I know there is already an answer to this but I just found a better solution using the variableWidth parameter, just set it to true in the settings of each breakpoint, like this:

$('#featured-articles').slick({
  arrows: true,
  autoplay: true,
  autoplaySpeed: 3000,
  dots: true,
  draggable: false,
  fade: true,
  infinite: false,
  responsive: [
  {
    breakpoint: 620,
    settings: {
        arrows: true,
        variableWidth: true
    }
  },
  {
    breakpoint: 345,
    settings: {
        arrows: true,
        variableWidth: true
    }
  }
  ]
});

If I were you and wanted to do so, I wouldn't use my User entity in Controller layer.Instead I create and use UserDto (Data transfer object) to communicate with business(Service) layer and Controller. You can use Apache BeanUtils(copyProperties method) to copy data from User entity to UserDto.

Add the following css class

.dropdown-menu {
    width: 300px !important;
    height: 400px !important;
}

Of course you can use what matches your need.

I too have faced similar issue when i started to work on Hibernate. All in all i can say is in the createQuery one needs to pass the name of the entity class not the table name to which the entity is mapped to.

res = ActiveRecord::Base.connection_pool.with_connection { |con| con.exec_query( "SELECT 1;" ) }

The above code is an example for

1. executing arbitrary SQL on your database-connection
2. returning the connection back to the connection pool afterwards

(2018) the new python requests library has simplified this process, we can use the 'files' variable to signal that we want to upload a multipart-encoded file

url = 'http://httpbin.org/post'
files = {'file': open('report.xls', 'rb')}

r = requests.post(url, files=files)
r.text

Please remove . from your target it should be a id

<a href="#bannerformmodal" data-toggle="modal" data-target="#bannerformmodal">Load me</a>

Also you have to give your modal id like below

<div class="modal fade bannerformmodal" tabindex="-1" role="dialog" aria-labelledby="bannerformmodal" aria-hidden="true" id="bannerformmodal">

Here is the solution in a fiddle.

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

I solved the problem by removing ~/Library/Caches/com.apple.amp.itmstransporter. For safety, renaming will be better,

cd ~/Library/Caches
mv com.apple.amp.itmstransporter com.apple.amp.itmstransporter.old

Then, xcrun altool uploaded my ipa successfully.
By the way, I'm using Xcode 11.x & 12.2, macOS Catalina.

I had similar issues when using 'java' at the beginning of the package name, e.g. java.jem.pc

Check your console output, I was receiving:

Exception in thread "main" java.lang.SecurityException: Prohibited package name: java.jem.pc

In linux (Debian Jessie for example):

apt-get install php7.0-intl

will make the job to you due will create a simbolic link to it.

I have also dealt with this exception after a fully working context.xml setup was adjusted. I didn't want environment details in the context.xml, so I took them out and saw this error. I realized I must fully create this datasource resource in code based on System Property JVM -D args.

Original error with just user/pwd/host removed: org.apache.tomcat.jdbc.pool.ConnectionPool init SEVERE: Unable to create initial connections of pool.

Removed entire contents of context.xml and try this: Initialize on startup of app server the datasource object sometime before using first connection. If using Spring this is good to do in an @Configuration bean in @Bean Datasource constructor.

package to use: org.apache.tomcat.jdbc.pool.*

PoolProperties p = new PoolProperties();
p.setUrl(jdbcUrl);
            p.setDriverClassName(driverClass);

            p.setJmxEnabled(true);
            p.setTestWhileIdle(false);
            p.setTestOnBorrow(true);
            p.setValidationQuery("SELECT 1");
            p.setTestOnReturn(false);
            p.setValidationInterval(30000);
            p.setValidationQueryTimeout(100);

              "org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer");
            org.apache.tomcat.jdbc.pool.DataSource ds = new org.apache.tomcat.jdbc.pool.DataSource();
            ds.setPoolProperties(p);
            return ds;

What I've done to solve this problem is save the workbook. This forces it to refresh before closing.

The same approach works for copying many formulas before performing the next operation.

Your code isn't working, because the hidden attibute is not supported in versions of IE before v11

If you need to support IE before version 11, add a CSS style to hide when the hidden attribute is present:

*[hidden] { display: none; }

If you are converting a varchar to int make sure you do not have decimal places.

For example, if you are converting a varchar field with value (12345.0) to an integer then you get this conversion error. In my case I had all my fields with .0 as ending so I used the following statement to globally fix the problem.

CONVERT(int, replace(FIELD_NAME,'.0',''))

I think you are not configured properly,

if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(use the above send mail path only and it will work)

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]

Now you have done!! create php file with mail function and send mail from localhost.

Update

First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()).

You can set the following settings in your PHP.ini:

ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");

Please see Why does the property I want to mock need to be virtual?

You may have to write a wrapper interface or mark the property as virtual/abstract as Moq creates a proxy class that it uses to intercept calls and return your custom values that you put in the .Returns(x) call.

Following steps has fixed my issue.

(1) Moved the website to a Dedicated application pool.

(2) Changed the Managed Pipeline Mode from integrated to Classic.

(3) Set Enable 32-Bit Applications from false to true.

ASP pages are working fine now!

You did not add # before id of the button. You do not have right selector in your jquery code. So jquery is never execute in your button click. its submitted your form directly not passing any ajax request.

See documentation: http://api.jquery.com/category/selectors/
its your friend.

Try this:

It seems that id: $("#Shareitem").val() is wrong if you want to pass the value of

<input type="hidden" name="id" value="" id="id">

you need to change this line:

id: $("#Shareitem").val()

by

id: $("#id").val()

All together:

 <script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
    <script>
    $(document).ready(function(){
      $("#Shareitem").click(function(e){
          e.preventDefault();
        $.ajax({type: "POST",
                url: "/imball-reagens/public/shareitem",
                data: { id: $("#Shareitem").val(), access_token: $("#access_token").val() },
                success:function(result){
          $("#sharelink").html(result);
        }});
      });
    });
    </script>

Use Controls object

For i = 1 To X
    Controls("Label" & i).Caption =  MySheet.Cells(i + 1, i).Value
Next

Simply, @Id: This annotation specifies the primary key of the entity. 

@GeneratedValue: This annotation is used to specify the primary key generation strategy to use. i.e Instructs database to generate a value for this field automatically. If the strategy is not specified by default AUTO will be used. 

GenerationType enum defines four strategies: 
1. Generation Type . TABLE, 
2. Generation Type. SEQUENCE,
3. Generation Type. IDENTITY   
4. Generation Type. AUTO

GenerationType.SEQUENCE

With this strategy, underlying persistence provider must use a database sequence to get the next unique primary key for the entities. 

GenerationType.TABLE

With this strategy, underlying persistence provider must use a database table to generate/keep the next unique primary key for the entities. 

GenerationType.IDENTITY
This GenerationType indicates that the persistence provider must assign primary keys for the entity using a database identity column. IDENTITY column is typically used in SQL Server. This special type column is populated internally by the table itself without using a separate sequence. If underlying database doesn't support IDENTITY column or some similar variant then the persistence provider can choose an alternative appropriate strategy. In this examples we are using H2 database which doesn't support IDENTITY column.

GenerationType.AUTO
This GenerationType indicates that the persistence provider should automatically pick an appropriate strategy for the particular database. This is the default GenerationType, i.e. if we just use @GeneratedValue annotation then this value of GenerationType will be used. 

Reference:- https://www.logicbig.com/tutorials/java-ee-tutorial/jpa/jpa-primary-key.html

The code works for me. (after adding missing except clause / import statements)

Did you put \ in the original code?

urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/' \
              + stock + '/chartdata;type=quote;range=5d/csv'

If you omit it, it could be a cause of the exception:

>>> stock = 'GOOG'
>>> urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/'
>>> + stock + '/chartdata;type=quote;range=5d/csv'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: bad operand type for unary +: 'str'

BTW, string(e) should be str(e).

In our case we were getting UnmarshalException because a wrong Java package was specified in the following. The issue was resolved once the right package was in place:

@Bean
public Unmarshaller tmsUnmarshaller() {
    final Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller();
    jaxb2Marshaller
            .setPackagesToScan("java.package.to.generated.java.classes.for.xsd");
    return jaxb2Marshaller;
}

I solved this problem.

My Java version was the 1.6 and I found that was using 1.7 with CDI however after that I changed the Java version to 1.7 and import the package javax.faces.bean.ManagedBean and everything worked.

Thanks @PM77-1

Try this method to get path of original image captured by camera.

public String getOriginalImagePath() {
        String[] projection = { MediaStore.Images.Media.DATA };
        Cursor cursor = getActivity().managedQuery(
                MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                projection, null, null, null);
        int column_index_data = cursor
                .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToLast();

        return cursor.getString(column_index_data);
    }

This method will return path of the last image captured by camera. So this path would be of original image not of thumbnail bitmap.

The .btn classes are designed for , or elements (though some browsers may apply a slightly different rendering).

If you’re using .btn classes on elements that are used to trigger functionality ex. collapsing content, these links should be given a role="button" to adequately communicate their meaning to assistive technologies such as screen readers. I hope this help.

try this query below:

Insert into tab1 (tab1.column1,tab1.column2) 
select tab2.column1, 'hard coded  value' 
from tab2 
where tab2.column='value';

I had the same issue. When compared the java version mentioned in the pom.xml file is different and the JAVA_HOME env variable was pointing to different version of jdk.

Have the JAVA_HOME and pom.xml updated to the same jdk installation path

To make it short, it means that you lacked some "dependencies" for the libraries you wanted to use. Before trying to use any kind of library, first it is suggested to look up whether it needs another library in python "family". What do I mean?

Downloading "dlls" is something that I avoid. I had the same problem with another library "kivy". The problem occurred when I wanted to use Python 3.4v instead of 3.5 Everything was working correctly in 3.5 but I just wanted to use the stable version for kivy which is 3.4 as they officially "advise". So, I switched to 3.4 but then I had the very same "dll" error saying lots of things are missing. So I checked the website and learned that I needed to install extra "dependencies" from the official website of kivy, then the problem got solved.

I was looking for the onClick option to set the title and body of the modal based on the item in a list. T145's answer helped a lot, so I wanted to share how I used it.

Make sure the tag containing the JavaScript function is of type text/javascript to avoid conflicts:

<script type="text/javascript"> function showMyModalSetTitle(myTitle, myBodyHtml) {

   /*
    * '#myModayTitle' and '#myModalBody' refer to the 'id' of the HTML tags in
    * the modal HTML code that hold the title and body respectively. These id's
    * can be named anything, just make sure they are added as necessary.
    *
    */

   $('#myModalTitle').html(myTitle);
   $('#myModalBody').html(myBodyHtml);

   $('#myModal').modal('show');
}</script>

This function can now be called in the onClick method from inside an element such as a button:

<button type="button" onClick="javascript:showMyModalSetTitle('Some Title', 'Some body txt')"> Click Me! </button>

I was using Spring Data JPA with PostgreSql and during UPDATE call it was showing errors-

• 'could not extract ResultSet' and another one.
• org.springframework.dao.InvalidDataAccessApiUsageException: Executing an update/delete query; nested exception is javax.persistence.TransactionRequiredException: Executing an update/delete query. (Showing Transactional required.)

Actually, I was missing two required Annotations.

• @Transactional and
• @Modifying

With-

@Query(vlaue = " UPDATE DB.TABLE SET Col1 = ?1 WHERE id = ?2 ", nativeQuery = true)
void updateCol1(String value, long id);

This is because you define your "doc" variable outside of your click event. The first time you click the button the doc variable contains a new jsPDF object. But when you click for a second time, this variable can't be used in the same way anymore. As it is already defined and used the previous time.

change it to:

$(function () {

    var specialElementHandlers = {
        '#editor': function (element,renderer) {
            return true;
        }
    };
 $('#cmd').click(function () {
        var doc = new jsPDF();
        doc.fromHTML(
            $('#target').html(), 15, 15, 
            { 'width': 170, 'elementHandlers': specialElementHandlers }, 
            function(){ doc.save('sample-file.pdf'); }
        );

    });  
});

and it will work.

Try this:

$objPHPExcel->getActiveSheet()->getRowDimension('1')->setRowHeight(40);

As you can see in the below source code, BeanUtils.copyProperties internally uses reflection and there's additional internal cache lookup steps as well which is going to add cost wrt performance

 private static void copyProperties(Object source, Object target, @Nullable Class<?> editable,
                @Nullable String... ignoreProperties) throws BeansException {

            Assert.notNull(source, "Source must not be null");
            Assert.notNull(target, "Target must not be null");

            Class<?> actualEditable = target.getClass();
            if (editable != null) {
                if (!editable.isInstance(target)) {
                    throw new IllegalArgumentException("Target class [" + target.getClass().getName() +
                            "] not assignable to Editable class [" + editable.getName() + "]");
                }
                actualEditable = editable;
            }
            **PropertyDescriptor[] targetPds = getPropertyDescriptors(actualEditable);**
            List<String> ignoreList = (ignoreProperties != null ? Arrays.asList(ignoreProperties) : null);

            for (PropertyDescriptor targetPd : targetPds) {
                Method writeMethod = targetPd.getWriteMethod();
                if (writeMethod != null && (ignoreList == null || !ignoreList.contains(targetPd.getName()))) {
                    PropertyDescriptor sourcePd = getPropertyDescriptor(source.getClass(), targetPd.getName());
                    if (sourcePd != null) {
                        Method readMethod = sourcePd.getReadMethod();
                        if (readMethod != null &&
                                ClassUtils.isAssignable(writeMethod.getParameterTypes()[0], readMethod.getReturnType())) {
                            try {
                                if (!Modifier.isPublic(readMethod.getDeclaringClass().getModifiers())) {
                                    readMethod.setAccessible(true);
                                }
                                Object value = readMethod.invoke(source);
                                if (!Modifier.isPublic(writeMethod.getDeclaringClass().getModifiers())) {
                                    writeMethod.setAccessible(true);
                                }
                                writeMethod.invoke(target, value);
                            }
                            catch (Throwable ex) {
                                throw new FatalBeanException(
                                        "Could not copy property '" + targetPd.getName() + "' from source to target", ex);
                            }
                        }
                    }
                }
            }
        }

So it's better to use plain setters given the cost reflection

Building on Joan-Diego Rodriguez's routine with Jordi's approach and some of Jacek Kotowski's code - This function converts any table name for the active workbook into a usable address for SQL queries.

Note to MikeL: Addition of "[#All]" includes headings avoiding problems you reported.

Function getAddress(byVal sTableName as String) as String 

    With Range(sTableName & "[#All]")
        getAddress= "[" & .Parent.Name & "$" & .Address(False, False) & "]"
    End With

End Function

Download desired version of hadoop folder (Say if you are installing spark on Windows then hadoop version for which your spark is built for) from this link as zip.

Extract the zip to desired directory. You need to have directory of the form hadoop\bin (explicitly create such hadoop\bin directory structure if you want) with bin containing all the files contained in bin folder of the downloaded hadoop. This will contain many files such as hdfs.dll, hadoop.dll etc. in addition to winutil.exe.

Now create environment variable HADOOP_HOME and set it to <path-to-hadoop-folder>\hadoop. Then add ;%HADOOP_HOME%\bin; to PATH environment variable.

Open a "new command prompt" and try rerunning your command.

you should receive use page,like this

 @Override
public Page<UserBoard> findLatestBoards() {
    PageRequest request = new PageRequest(
                 0, PresentationUtil.PAGE_SIZE, 
                 Sort.Direction.DESC, "boardId"
    );
    return boardRepository.findAll(request).getContent();
}

Resolved the problem using Jackson library. Prints are called out of Main class and all POJO classes are created. Here is the code snippets.

Value for getChildren is: ddec1caa-a97f-4922-833f-632da07ffc11
Value for getChildren is: true

Password is a reserved word. Bracket that field name to avoid confusing the db engine.

You are specifying .fixedbutton in your CSS (a class) and specifying the id on the element itself.

Change your CSS to the following, which will select the id fixedbutton

#fixedbutton {
    position: fixed;
    bottom: 0px;
    right: 0px; 
}

Here's a jsFiddle courtesy of JoshC.

You can use a heredoc. e.g. from a prompt:

$ sqlplus -s username/password@oracle_instance <<EOF
set feed off
set pages 0
select count(*) from table;
exit
EOF

so sqlplus will consume everything up to the EOF marker as stdin.

In my case the underlying system account through which the package was running was locked out. Once we got the system account unlocked and reran the package, it executed successfully. The developer said that he got to know of this while debugging wherein he directly tried to connect to the server and check the status of the connection.

One thing you can do is get rid of all those onclick attributes and do it the right way with bootstrap. You don't need to open them manually; you can specify the trigger and even subscribe to events before the modal opens so that you can do your operations and populate data in it.

I am just going to show as a static example which you can accommodate in your real world.

On each of your <tr>'s add a data attribute for id (i.e. data-id) with the corresponding id value and specify a data-target, which is a selector you specify, so that when clicked, bootstrap will select that element as modal dialog and show it. And then you need to add another attribute data-toggle=modal to make this a trigger for modal.

  <tr data-toggle="modal" data-id="1" data-target="#orderModal">
            <td>1</td>
            <td>24234234</td>
            <td>A</td>
  </tr>
  <tr data-toggle="modal" data-id="2" data-target="#orderModal">
            <td>2</td>
            <td>24234234</td>
            <td>A</td>
        </tr>
  <tr data-toggle="modal" data-id="3" data-target="#orderModal">
            <td>3</td>
            <td>24234234</td>
            <td>A</td>
  </tr>

And now in the javascript just set up the modal just once and event listen to its events so you can do your work.

$(function(){
    $('#orderModal').modal({
        keyboard: true,
        backdrop: "static",
        show:false,

    }).on('show', function(){ //subscribe to show method
          var getIdFromRow = $(event.target).closest('tr').data('id'); //get the id from tr
        //make your ajax call populate items or what even you need
        $(this).find('#orderDetails').html($('<b> Order Id selected: ' + getIdFromRow  + '</b>'))
    });
});

Demo

Do not use inline click attributes any more. Use event bindings instead with vanilla js or using jquery.

ARIA does not change functionality, it only changes the presented roles/properties to screen reader users. WebAIM’s WAVE toolbar identifies ARIA roles on the page.

It seems to based on advertisement data, particularly the manufacturer data:

<company identifier (2 bytes)> <type (1 byte)> <data length (1 byte)>
    <uuid (16 bytes)> <major (2 bytes)> <minor (2 bytes)> <RSSI @ 1m>

• Apple Company Identifier (Little Endian), 0x004c

Ok. I found a solution.

I had a similar problem and I fixed with

    $('#CompId').select2({
              dropdownParent: $('#AssetsModal')
    });

and modal with select

    <div class="modal fade" id="AssetsModal" role="dialog"

but I don't know why the select menu is smaller than other fields

and it starting like that when start using select2. When I remove it, all is ok.

Is there some one to share some experince about that.

Thanks.

Make sure your Java version matches the project's Java version requirement. This could be an another cause for such kinds of issues.

My variation of the solution: (scss)

  .modal {
        .modal-dialog.modal-fs {
            width: 100%;
            margin: 0;
            box-shadow: none;
            height: 100%;
            .modal-content {
                border: none;
                border-radius: 0;
                box-shadow: none;
                box-shadow: none;
                height: 100%;
            }
        }
    }

(css)

.modal .modal-dialog.modal-fs {
  width: 100%;
  margin: 0;
  box-shadow: none;
  height: 100%;
}
.modal .modal-dialog.modal-fs .modal-content {
  border: none;
  border-radius: 0;
  box-shadow: none;
  box-shadow: none;
  height: 100%;
}

I would start by turning off TCP offloading. There have been a few things that cause intermittent connectivity issues and this is the one that is usually the culprit.

Note: I have seen this setting cause problems on Win Server 2003 and Win Server 2008

I do it this way:

<!-- global template loaded in all pages // -->
     <div id="NewsModal" class="modal fade" tabindex="-1" role="dialog" data-ajaxload="true" aria-labelledby="newsLabel" aria-hidden="true">
            <div class="modal-dialog">
                <div class="modal-content">
                    <div class="modal-header">
                        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
                        <h3 class="newsLabel"></h3>
                    </div>
                    <div class="modal-body">
                            <div class="loading">
                                <span class="caption">Loading...</span>
                               <img src="/images/loading.gif" alt="loading">

                    <div class="modal-footer caption">
                        <button class="btn btn-right default modal-close" data-dismiss="modal">Close</button>
                    </div>
                </div>
            </div>
        </div>

Here is my a href:

<a href="#NewsModal" onclick="remote=\'modal_newsfeed.php?USER='.trim($USER).'&FUNCTION='.trim(urlencode($FUNCTIONCODE)).'&PATH_INSTANCE='.$PATH_INSTANCE.'&ALL=ALL\'
                                        remote_target=\'#NewsModal .modal-body\'" role="button" data-toggle="modal">See All Notifications <i class="m-icon-swapright m-icon-dark"></i></a>

This has nothing to do with using PDO, it's just that you are confusing INSERT and UPDATE.

Here's the difference:

• INSERT creates a new row. I'm guessing that you really want to create a new row.
• UPDATE changes the values in an existing row, but if this is what you're doing you probably should use a WHERE clause to restrict the change to a specific row, because the default is that it applies to every row.

So this will probably do what you want:

$sql = "INSERT INTO `access_users`   
  (`contact_first_name`,`contact_surname`,`contact_email`,`telephone`) 
  VALUES (:firstname, :surname, :email, :telephone);
  ";

Note that I've also changed the order of columns; the order of your columns must match the order of values in your VALUES clause.

MySQL also supports an alternative syntax for INSERT:

$sql = "INSERT INTO `access_users`   
  SET `contact_first_name` = :firstname,
    `contact_surname` = :surname,
    `contact_email` = :email,
    `telephone` = :telephone
  ";

This alternative syntax looks a bit more like an UPDATE statement, but it creates a new row like INSERT. The advantage is that it's easier to match up the columns to the correct parameters.

You can get another validation on this tutorial : http://twitterbootstrap.org/bootstrap-form-validation

They use JQuery validation.

jquery.validate.js

jquery.validate.min.js

jquery-1.7.1.min.js

And you'll get the source code there.

If you are working on your own, and you want the closest thing to OOP as you would find in Java or C# or C++, see the javascript library, CrxOop. CrxOop provides syntax somewhat familiar to Java developers.

Just be careful, Java's OOP is not the same as that found in Javascript. To get the same behavior as in Java, use CrxOop's classes, not CrxOop's structures, and make sure all your methods are virtual. An example of the syntax is,

crx_registerClass("ExampleClass", 
{ 
    "VERBOSE": 1, 

    "public var publicVar": 5, 
    "private var privateVar": 7, 

    "public virtual function publicVirtualFunction": function(x) 
    { 
        this.publicVar1 = x;
        console.log("publicVirtualFunction"); 
    }, 

    "private virtual function privatePureVirtualFunction": 0, 

    "protected virtual final function protectedVirtualFinalFunction": function() 
    { 
        console.log("protectedVirtualFinalFunction"); 
    }
}); 

crx_registerClass("ExampleSubClass", 
{ 
    VERBOSE: 1, 
    EXTENDS: "ExampleClass", 

    "public var publicVar": 2, 

    "private virtual function privatePureVirtualFunction": function(x) 
    { 
        this.PARENT.CONSTRUCT(pA);
        console.log("ExampleSubClass::privatePureVirtualFunction"); 
    } 
}); 

var gExampleSubClass = crx_new("ExampleSubClass", 4);

console.log(gExampleSubClass.publicVar);
console.log(gExampleSubClass.CAST("ExampleClass").publicVar);

The code is pure javascript, no transpiling. The example is taken from a number of examples from the official documentation.

UPDATE 2018 MAY:

Alternatively, you can embed Edge browser, but only targetting windows 10.

In my case the problem was because of conflicting Jars.

It sounds like the populate method is what your looking for. First make small change to your post schema:

var postSchema = new Schema({
    name: String,
    postedBy: {type: mongoose.Schema.Types.ObjectId, ref: 'User'},
    dateCreated: Date,
    comments: [{body:"string", by: mongoose.Schema.Types.ObjectId}],
});

Then make your model:

var Post = mongoose.model('Post', postSchema);

Then, when you make your query, you can populate references like this:

Post.findOne({_id: 123})
.populate('postedBy')
.exec(function(err, post) {
    // do stuff with post
});

This occurs if the password for the database is not given.

default="postgres://postgres:[email protected]:5432/DBname"

If you wants to center the dropdown, this is the solution.

<ul class="dropdown-menu" style="right:auto; left: auto;">

Having the same error trying to install matplotlib for Python 3, those solutions didn't work for me. It was just a matter of dependencies, though it wasn't clear in the error message.

I used sudo apt-get build-dep python3-matplotlib then sudo pip3 install matplotlib and it worked.

Hope it'll help !

How to bring back “Browser mode” in IE11?

Easy way to bring back is just go to Emulation (ctrl +8)

and do change user agent string. (see attached image)

My solution was to run

mysql_upgrade -u root

Scenario: I updated the MySQL version on my Mac with 'homebrew upgrade'. Afterwards, some stuff worked, but other commands raised the error described in the question.

This is an old topic, but in case anyone else is still looking...

I was having trouble after an undock event. An open db connection saved in a global object would error, even after reconnecting to the network. This was due to the TCP connection being forcibly terminated by remote host. (Error -2147467259: TCP Provider: An existing connection was forcibly closed by the remote host.)

However, the error would only show up after the first transaction was attempted. Up to that point, neither Connection.State nor Connection.Version (per solutions above) would reveal any error.

So I wrote the small sub below to force the error - hope it's useful.

Performance testing on my setup (Access 2016, SQL Svr 2008R2) was approx 0.5ms per call.

Function adoIsConnected(adoCn As ADODB.Connection) As Boolean

    '----------------------------------------------------------------
    '#PURPOSE: Checks whether the supplied db connection is alive and
    '          hasn't had it's TCP connection forcibly closed by remote
    '          host, for example, as happens during an undock event
    '#RETURNS: True if the supplied db is connected and error-free, 
    '          False otherwise
    '#AUTHOR:  Belladonna
    '----------------------------------------------------------------

    Dim i As Long
    Dim cmd As New ADODB.Command

    'Set up SQL command to return 1
    cmd.CommandText = "SELECT 1"
    cmd.ActiveConnection = adoCn

    'Run a simple query, to test the connection
    On Error Resume Next
    i = cmd.Execute.Fields(0)
    On Error GoTo 0

    'Tidy up
    Set cmd = Nothing

    'If i is 1, connection is open
    If i = 1 Then
        adoIsConnected = True
    Else
        adoIsConnected = False
    End If

End Function

If you are maintaining one more cinfiguration file for app.config , Don't include any key in parent page.

Parent Page : app.config

<appSettings configSource="appSettings.config">
    <add key="ClientSettings" value="venice" /> <!-- Don't add Key Here -->
</appSettings>

Child Page : appSettings.config

<appSettings>
  <add key="ClientSettings" value="venice"/> <!-- add Here -->
</appSettings>

You need to handle it via ajax submit.

Something like this:

$(function(){
    $('#subscribe-email-form').on('submit', function(e){
        e.preventDefault();
        $.ajax({
            url: url, //this is the submit URL
            type: 'GET', //or POST
            data: $('#subscribe-email-form').serialize(),
            success: function(data){
                 alert('successfully submitted')
            }
        });
    });
});

A better way would be to use a django form, and then render the following snippet:

<form>
    <div class="modal-body">
        <input type="email" placeholder="email"/>
        <p>This service will notify you by email should any issue arise that affects your plivo service.</p>
    </div>
    <div class="modal-footer">
        <input type="submit" value="SUBMIT" class="btn"/>
    </div>
</form>

via the context - example : {{form}}.

Try mono:

This download works on all versions of Windows XP, 2003, Vista and Windows 7.

The easiest solution:

CREATE USER dev WITH PASSWORD 'dev';
CREATE DATABASE test_development;
GRANT ALL PRIVILEGES ON DATABASE test_development to dev;
ALTER ROLE dev CREATEROLE CREATEDB;

Step 1: Define attributes in $appends
Step 2: Define accessor for that attributes.
Example:

<?php
...

class Movie extends Model{

    protected $appends = ['cover'];

    //define accessor
    public function getCoverAttribute()
    {
        return json_decode($this->InJson)->cover;
    }

Either remove the below code from the pom.xml or correct your java version to make it work.

  <plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.0</version>
    <configuration>
      <source>1.6</source>
      <target>1.6</target>
    </configuration>
  </plugin>

My solution is that i want data from all docs and i dont want _id, so

User.find({}, {_id:0, keyToShow:1, keyToNotShow:0})

Try this code,

public void ConnectToAccess()
{
    System.Data.OleDb.OleDbConnection conn = new 
        System.Data.OleDb.OleDbConnection();
    // TODO: Modify the connection string and include any
    // additional required properties for your database.
    conn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;" +
        @"Data source= C:\Documents and Settings\username\" +
        @"My Documents\AccessFile.mdb";
    try
    {
        conn.Open();
        // Insert code to process data.
    }
        catch (Exception ex)
    {
        MessageBox.Show("Failed to connect to data source");
    }
    finally
    {
        conn.Close();
    }
}

Well you're casting OrdersPerHour to an int?

OrdersPerHour = (int?)dbcommand.ExecuteScalar();

Yet your method signature is int:

static int OrdersPerHour(string User)

The two have to match.

Also a quick suggestion -> Use parameters in your query, something like:

string query = "SELECT COUNT(ControlNumber) FROM Log WHERE DateChanged > ? AND User = ? AND Log.EndStatus in ('Needs Review', 'Check Search', 'Vision Delivery', 'CA Review', '1TSI To Be Delivered')";
OleDbCommand dbcommand = new OleDbCommand(query, conn);
dbcommand.Parameters.Add(curTime.AddHours(-1));
dbcommand.Parameters.Add(User);

Ok found out the Tomcat file server.xml must be configured as well for the data source to work. So just add:

<Resource 
auth="Container" 
driverClassName="org.apache.derby.jdbc.EmbeddedDriver" 
maxActive="20" 
maxIdle="10" 
maxWait="-1" 
name="ds/flexeraDS" 
type="javax.sql.DataSource" 
url="jdbc:derby:flexeraDB;create=true" 
  />

You can export the query results to a text file (or insert statements, or even pdf) by right-clicking on Query Result row (any row) and choose Export

using Sql Developer 3.0

See SQL Developer downloads for latest versions

SELECT *

    )

These days, socket.on('connect', ...) is not working for me. I use the below code to check at 1st connecting.

if (socket.connected)
  console.log('socket.io is connected.')

and use this code when reconnected.

socket.on('reconnect', ()=>{
  //Your Code Here
});

I found it sufficient to specify the pypi host as trusted. Example:

pip install --trusted-host pypi.python.org pytest-xdist
pip install --trusted-host pypi.python.org --upgrade pip

This solved the following error:

  Could not fetch URL https://pypi.python.org/simple/pytest-cov/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:600) - skipping
  Could not find a version that satisfies the requirement pytest-cov (from versions: )
No matching distribution found for pytest-cov

Update April 2018: To anyone getting the TLSV1_ALERT_PROTOCOL_VERSION error: it has nothing to do with trusted-host/verification issue of the OP or this answer. Rather the TLSV1 error is because your interpreter does not support TLS v1.2, you must upgrade your interpreter. See for example https://news.ycombinator.com/item?id=13539034, http://pyfound.blogspot.ca/2017/01/time-to-upgrade-your-python-tls-v12.html and https://bugs.python.org/issue17128.

Update Feb 2019: For some it may be sufficient to upgrade pip. If the above error prevents you from doing this, use get-pip.py. E.g. on Linux,

curl https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py

The other solutions should work, but here is a solution for docker-compose.

To fix that error, you need to pass $DISPLAY and .X11-unix to docker, as well as grant the user who started docker access to xhost.

Within docker-compose.yml file:

version: '2'
services:
    node:
        build: .
        container_name: node
        environment:
            - DISPLAY
        volumes:
            - /tmp/.X11-unix:/tmp/.X11-unix

In terminal or script:

• xhost +si:localuser:$USER
• xhost +local:docker
• export DISPLAY=$DISPLAY
• docker-compose up

try the following program

using System;
using System.Data;
using System.Windows.Forms;
using System.Data.SqlClient;

namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        System.Data.OleDb.OleDbConnection MyConnection;
        System.Data.DataSet DtSet;
        System.Data.OleDb.OleDbDataAdapter MyCommand;
        MyConnection = new System.Data.OleDb.OleDbConnection(@"provider=Microsoft.Jet.OLEDB.4.0;Data Source='c:\csharp.net-informations.xls';Extended Properties=Excel 8.0;");
        MyCommand = new System.Data.OleDb.OleDbDataAdapter("select * from [Sheet1$]", MyConnection);
        MyCommand.TableMappings.Add("Table", "Net-informations.com");
        DtSet = new System.Data.DataSet();
        MyCommand.Fill(DtSet);
        dataGridView1.DataSource = DtSet.Tables[0];
        MyConnection.Close();
    }
}
} 

Actually I merged all your answers to my own solution how to solve the above problem:

1. I create the pubxml file according my needs
2. Then I copy all the parameters from pubxml file to my own list of parameters "/p:foo=bar" for msbuild.exe
3. I throw away the pubxml file

The result is like that:

msbuild /t:restore /t:build /p:WebPublishMethod=FileSystem /p:publishUrl=C:\builds\MyProject\ /p:DeleteExistingFiles=True /p:LastUsedPlatform="Any CPU" /p:Configuration=Release

For phone numbers you can simply exclude all non-digit characters with \D in regex:

import re

phone_number = '(619) 459-3635'
phone_number = re.sub(r"\D", "", phone_number)
print(phone_number)

You can use:

<script type="text/javascript">
    function prepareFrame() {
        var ifrm = document.createElement("iframe");
        ifrm.setAttribute("src", "http://google.com/");
        ifrm.style.width = "640px";
        ifrm.style.height = "480px";
        document.body.appendChild(ifrm);
    }
</script> 

also check basics of the iFrame element

Am I missing something to wonder why noone suggests OpenGL? To use it for 2d would be very simple. The OP only wants to color a pixel. It doesn't get simpler than glBegin/glColor/glVertex/glEnd.

There's not really a good way to do this, usually you see an extra item in the enum, i.e.

enum foobar {foo, bar, baz, quz, FOOBAR_NR_ITEMS};

So then you can do:

int fuz[FOOBAR_NR_ITEMS];

Still not very nice though.

But of course you do realize that just the number of items in an enum is not safe, given e.g.

enum foobar {foo, bar = 5, baz, quz = 20};

the number of items would be 4, but the integer values of the enum values would be way out of the array index range. Using enum values for array indexing is not safe, you should consider other options.

edit: as requested, made the special entry stick out more.

Nobody suggested Vagrant yet, so here it is, Vagrant box for OSX

vagrant init https://vagrant-osx.nyc3.digitaloceanspaces.com/osx-sierra-0.3.1.box
vagrant up

and you have a MACOS virtual machine. But according to Apple's EULA, you still need to run it on MacOS hardware :D But anywhere, here's one to all of you geeks who wiped MacOS and installed Ubuntu :D

Unfortunately, you can't run the editors from inside using SSH X-forwarding option.

When writing queries, this difference should be kept in mind :

DECLARE @A INT = 2

SELECT  @A = TBL.A
FROM    ( SELECT 1 A ) TBL
WHERE   1 = 2

SELECT  @A
/* @A is 2*/

---------------------------------------------------------------

DECLARE @A INT = 2

SET @A = ( 
            SELECT  TBL.A
            FROM    ( SELECT 1 A) TBL
            WHERE   1 = 2
         )

SELECT  @A
/* @A is null*/

I'm pretty sure you only have to register MappingJacksonHttpMessageConverter

(the easiest way to do that is through <mvc:annotation-driven /> in XML or @EnableWebMvc in Java)

The easiest way is to have a "wrapper" div element with a width set, and a left and right margin of auto.

Sample markup:

<!doctype html>
<html>
<head>
    <title></title>
    <style type="text/css">
        .wrapper { width: 960px; margin: 0 auto; background-color: #cccccc; }
        body { margin: 0; padding: 0 }
    </style>
</head>
<body>
    <div class="wrapper">
        your content...
    </div>
</body>
</html>

You can use a 1 pixel per 1 pixel Java applet embedded in the page and use that for compression.

It's not JavaScript and the clients will need a Java runtime but it will do what you need.

The issue is with this line

 xlo.Worksheets(1).Cells(2, 2) = TextBox1.Text

You have the textbox defined at some other location which you are not using here. Excel is unable to find the textbox object in the current sheet while this textbox was defined in xlw.

Hence replace this with

 xlo.Worksheets(1).Cells(2, 2) = worksheets("xlw").TextBox1.Text 

Use the builtin function zip():

In Python 3:

z = list(zip(x,y))

In Python 2:

z = zip(x,y)

Don't forget to look at the Javascript as well. My guess is that there is custom Javascript code getting executed when you click on the link and it's that Javascript that is generating the URL and navigating to it.

You can't. You can call a JS function from HTML outputted by PHP, but that's a whole 'nother thing.

i came here for the same problem, i couldn't find anywhere in my code where a certain user was making the action. apparently it was from a trigger that was using a user which was long deleted (db was restored from an older version) so in case you are puzzled as i were, take a look at your db events/triggers/routines. hope this will help someone.

Simply change,

dispatch_async(kBgQueue, ^{
     NSData *imgData = [NSData dataWithContentsOfURL:[NSURL URLWithString:   [NSString stringWithFormat:@"http://myurl.com/%@.jpg",[[myJson objectAtIndex:indexPath.row] objectForKey:@"movieId"]]]];
     dispatch_async(dispatch_get_main_queue(), ^{
        cell.poster.image = [UIImage imageWithData:imgData];
     });
 });

Into

    dispatch_async(kBgQueue, ^{
         NSData *imgData = [NSData dataWithContentsOfURL:[NSURL URLWithString:   [NSString stringWithFormat:@"http://myurl.com/%@.jpg",[[myJson objectAtIndex:indexPath.row] objectForKey:@"movieId"]]]];
         cell.poster.image = [UIImage imageWithData:imgData];
         dispatch_async(dispatch_get_main_queue(), ^{
            [self.tableView reloadRowsAtIndexPaths:indexPaths withRowAnimation:UITableViewRowAnimationNone];
         });
     });

Try to slightly modify your code:

Sub forEachWs()
    Dim ws As Worksheet
    For Each ws In ActiveWorkbook.Worksheets
        Call resizingColumns(ws)
    Next
End Sub

Sub resizingColumns(ws As Worksheet)
    With ws
        .Range("A:A").ColumnWidth = 20.14
        .Range("B:B").ColumnWidth = 9.71
        .Range("C:C").ColumnWidth = 35.86
        .Range("D:D").ColumnWidth = 30.57
        .Range("E:E").ColumnWidth = 23.57
        .Range("F:F").ColumnWidth = 21.43
        .Range("G:G").ColumnWidth = 18.43
        .Range("H:H").ColumnWidth = 23.86
        .Range("i:I").ColumnWidth = 27.43
        .Range("J:J").ColumnWidth = 36.71
        .Range("K:K").ColumnWidth = 30.29
        .Range("L:L").ColumnWidth = 31.14
        .Range("M:M").ColumnWidth = 31
        .Range("N:N").ColumnWidth = 41.14
        .Range("O:O").ColumnWidth = 33.86
    End With
End Sub

Note, resizingColumns routine takes parametr - worksheet to which Ranges belongs.

Basically, when you're using Range("O:O") - code operats with range from ActiveSheet, that's why you should use With ws statement and then .Range("O:O").

And there is no need to use global variables (unless you are using them somewhere else)

try Mozilla official site: https://developer.mozilla.org/en/DOM/window.onhashchange

cite as follow:

if ("onhashchange" in window) {
    alert("The browser supports the hashchange event!");
}

function locationHashChanged() {
    if (location.hash === "#somecoolfeature") {
        somecoolfeature();
    }
}

window.onhashchange = locationHashChanged;

All the above methods will work fine if your content-type is "application/-www-form-urlencoded". But if your content-type is "application/json" then you will have to do the following:

$params = json_decode(file_get_contents('php://input'), true); print_r($params);

I recommend use pod 'UITextView+Placeholder'

pod 'UITextView+Placeholder'

on your code

#import "UITextView+Placeholder.h"

////    

UITextView *textView = [[UITextView alloc] init];
textView.placeholder = @"How are you?";
textView.placeholderColor = [UIColor lightGrayColor];

Using java 8 Stream API could simplify your job.

public static boolean inArray(int[] array, int check) {
    return Stream.of(array).anyMatch(i -> i == check);
}

It's just you have the overhead of creating a new Stream from Array, but this gives exposure to use other Stream API. In your case you may not want to create new method for one-line operation, unless you wish to use this as utility. Hope this helps!

The actual problem is not IE8, but the hacks that you use for earlier versions of IE.

IE8 is pretty close to be standards compliant, so you shouldn't need any hacks at all for it, perhaps only some tweaks. The problem is if you are using some hacks for IE6 and IE7; you will have to make sure that they only apply to those versions and not IE8.

I made the web site of our company compatible with IE8 a while ago. The only thing that I actually changed was adding the meta tag that tells IE that the pages are IE8 compliant...

If you're fetching data using Wordpress, then you can access the number of rows returned using $wpdb->num_rows:

$wpdb->get_results( $wpdb->prepare('select * from mytable where foo = %s', $searchstring));
echo $wpdb->num_rows;

If you want a specific count based on a mysql count query then you do this:

$numrows = $wpdb->get_var($wpdb->prepare('SELECT COUNT(*) FROM mytable where foo = %s', $searchstring );
echo $numrows;

If you're running updates or deletes then the count of rows affected is returned directly from the function call:

$numrowsaffected = $wpdb->query($wpdb->prepare(
   'update mytable set val=%s where myid = %d', $valuetoupdate, $myid));

This applies also to $wpdb->update and $wpdb->delete.

To get all tables with columns columnA or ColumnB in the database YourDatabase:

SELECT DISTINCT TABLE_NAME 
    FROM INFORMATION_SCHEMA.COLUMNS
    WHERE COLUMN_NAME IN ('columnA','ColumnB')
        AND TABLE_SCHEMA='YourDatabase';

There are several more things you might want to audit, such as table/column names, computer/application from which an update was made, and more.

Now, this depends on how detailed auditing you really need and at what level.

We started building our own trigger-based auditing solution, and we wanted to audit everything and also have a recovery option at hand. This turned out to be too complex, so we ended up reverse engineering the trigger-based, third-party tool ApexSQL Audit to create our own custom solution.

Tips:

• Include before/after values

• Include 3-4 columns for storing the primary key (in case it’s a composite key)

• Store data outside the main database as already suggested by Robert

• Spend a decent amount of time on preparing reports – especially those you might need for recovery

• Plan for storing host/application name – this might come very useful for tracking suspicious activities

If you read all answer above and it still does not work...

Make sure that your PHP PDO connection string is fine. Not like mine:

$dbh = new PDO('"mysql:host=' . DB_HOST . ';dbname=' . DB_NAME, DB_USER, DB_PASS)

There is no information in error message what driver was not found.

After reinstalling all possible PDO and MySQL libraries I found out that there was " at start of my connection string.

While there is no functional difference between os.environ.get and os.getenv, there is a massive difference between os.putenv and setting entries on os.environ. os.putenv is broken, so you should default to os.environ.get simply to avoid the way os.getenv encourages you to use os.putenv for symmetry.

os.putenv changes the actual OS-level environment variables, but in a way that doesn't show up through os.getenv, os.environ, or any other stdlib way of inspecting environment variables:

>>> import os
>>> os.environ['asdf'] = 'fdsa'
>>> os.environ['asdf']
'fdsa'
>>> os.putenv('aaaa', 'bbbb')
>>> os.getenv('aaaa')
>>> os.environ.get('aaaa')

You'd probably have to make a ctypes call to the C-level getenv to see the real environment variables after calling os.putenv. (Launching a shell subprocess and asking it for its environment variables might work too, if you're very careful about escaping and --norc/--noprofile/anything else you need to do to avoid startup configuration, but it seems a lot harder to get right.)

In "classic" C language (C89/90) when you call an undeclared function, C assumes that it returns an int and also attempts to derive the types of its parameters from the types of the actual arguments (no, it doesn't assume that it has no parameters, as someone suggested before).

In your specific example the compiler would look at do_something(dest, src) call and implicitly derive a declaration for do_something. The latter would look as follows

int do_something(char *, char *)

However, later in the code you explicitly declare do_something as

char *do_something(char *, const char *)

As you can see, these declarations are different from each other. This is what the compiler doesn't like.

If you are using rails > 3 version, then there is a concept called asset pipeline. You could add your CSS to

app/assets/stylesheets

then it will automatically be picked up by the app. (this is useful as rails will automatically compress the CSS files)

You can map another entity based on this class (you should use entity-name in order to distinct the two) and the second one will be kind of dto (dont forget that dto has design issues ). you should define the second one as readonly and give it a good name in order to be clear that this is not a regular entity. by the way select only few columns is called projection , so google with it will be easier.

alternative - you can create named query with the list of fields that you need (you put them in the select ) or use criteria with projection

The difference appears when the special parameters are quoted. Let me illustrate the differences:

$ set -- "arg  1" "arg  2" "arg  3"

$ for word in $*; do echo "$word"; done
arg
1
arg
2
arg
3

$ for word in $@; do echo "$word"; done
arg
1
arg
2
arg
3

$ for word in "$*"; do echo "$word"; done
arg  1 arg  2 arg  3

$ for word in "$@"; do echo "$word"; done
arg  1
arg  2
arg  3

one further example on the importance of quoting: note there are 2 spaces between "arg" and the number, but if I fail to quote $word:

$ for word in "$@"; do echo $word; done
arg 1
arg 2
arg 3

and in bash, "$@" is the "default" list to iterate over:

$ for word; do echo "$word"; done
arg  1
arg  2
arg  3

Default assignments apply to class members, but not to local variables. As Eric Lippert explained it in this answer, Microsoft could have initialized locals by default, but they choose not to do it because using an unassigned local is almost certainly a bug.

A fix and elaboration of @Fredrik Mörk answer.

• Add a strings.resx Resource file to your project (or a different filename)
• Set Access Modifier to Public (in the opened strings.resx file tab)
• Add a string resouce in the resx file: (example: name Hello, value Hello)
• Save the resource file

Visual Studio auto-generates a respective strings class, which is actually placed in strings.Designer.cs. The class is in the same namespace that you would expect a newly created .cs file to be placed in.

This code always prints Hello, because this is the default resource and no language-specific resources are available:

Console.WriteLine(strings.Hello);

Now add a new language-specific resource:

• Add strings.fr.resx (for French)
• Add a string with the same name as previously, but different value: (name Hello, value Salut)

The following code prints Salut:

Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo("fr-FR");
Console.WriteLine(strings.Hello);

What resource is used depends on Thread.CurrentThread.CurrentUICulture. It is set depending on Windows UI language setting, or can be set manually like in this example. Learn more about this here.

You can add country-specific resources like strings.fr-FR.resx or strings.fr-CA.resx.

The string to be used is determined in this priority order:

• From country-specific resource like strings.fr-CA.resx
• From language-specific resource like strings.fr.resx
• From default strings.resx

Note that language-specific resources generate satellite assemblies.

Also learn how CurrentCulture differs from CurrentUICulture here.

// Store the formatted string in 'result'
String result = String.format("%4d", i * j);

// Write the result to standard output
System.out.println( result );

Sadly it appears that the /deep/ selector is deprecated (at least in Chrome) https://www.chromestatus.com/features/6750456638341120

In short it appears there is (currently) no long term solution other than to somehow get your child component to style things dynamically.

You could pass a style object to your child and have it applied via:
<div [attr.style]="styleobject">

Or if you have a specific style you can use something like:
<div [style.background-color]="colorvar">

Could you please try this ?

Create another item in post such as post.link then assign the link to it before send post to the render function.

post.link = '/posts/+ id.toString();

So, the above render function should be following instead.

return <li key={post.id}><a href={post.link}>{post.title}</a></li>

For temporary testing during development we can disable it by opening chrome with disabled web security like this.

Open command line terminal and go to folder where chrome is installed i.e. C:\Program Files (x86)\Google\Chrome\Application

Enter this command:

chrome.exe --user-data-dir="C:/Chrome dev session" --disable-web-security

A new browser window will open with disabled web security. Use it only for testing your app.

Always show errors on a testing server. Never show errors on a production server.

Write a script to determine whether the page is on a local, testing, or live server, and set $state to "local", "testing", or "live". Then:

if( $state == "local" || $state == "testing" )
{
    ini_set( "display_errors", "1" );
    error_reporting( E_ALL & ~E_NOTICE );
}
else
{
    error_reporting( 0 );
}

After a bit of time (and more searching), I found this blog entry by Jomo Fisher.

One of the recent problems we’ve seen is that, because of the support for side-by-side runtimes, .NET 4.0 has changed the way that it binds to older mixed-mode assemblies. These assemblies are, for example, those that are compiled from C++\CLI. Currently available DirectX assemblies are mixed mode. If you see a message like this then you know you have run into the issue:

Mixed mode assembly is built against version 'v1.1.4322' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

[Snip]

The good news for applications is that you have the option of falling back to .NET 2.0 era binding for these assemblies by setting an app.config flag like so:

<startup useLegacyV2RuntimeActivationPolicy="true">
  <supportedRuntime version="v4.0"/>
</startup>

So it looks like the way the runtime loads mixed-mode assemblies has changed. I can't find any details about this change, or why it was done. But the useLegacyV2RuntimeActivationPolicy attribute reverts back to CLR 2.0 loading.

Also, I add to do the following steps so that the git repo would be correctly linked with the IDE:

 $ git reset <commit #>

 $ git checkout <file/path>

I hope this was helpful!!

Share and install userscript with one-click

To make auto-install (but mannually confirm), You can make gist (gist.github.com) with <filename>.user.js filename to get on-click installation when you click on Raw and get this page:

How to do this ?

1. Name your gist <filename>.user.js, write your code and click on "Create".
   

2. In the gist page, click on Raw to get installation page (first screen).
   

3. Check the code and install it.

The text uses combining characters, also known as combining marks. See section 2.11 of Combining Characters in the Unicode Standard (PDF).

In Unicode, character rendering does not use a simple character cell model where each glyph fits into a box with given height. Combining marks may be rendered above, below, or inside a base character

So you can easily construct a character sequence, consisting of a base character and “combining above” marks, of any length, to reach any desired visual height, assuming that the rendering software conforms to the Unicode rendering model. Such a sequence has no meaning of course, and even a monkey could produce it (e.g., given a keyboard with suitable driver).

And you can mix “combining above” and “combining below” marks.

The sample text in the question starts with:

• LATIN CAPITAL LETTER H - H
• COMBINING LATIN SMALL LETTER T - ͭ
• COMBINING GREEK KORONIS - ̓
• COMBINING COMMA ABOVE - ̓
• COMBINING DOT ABOVE - ̇

format-date(current-date(), '[M01]/[D01]/[Y0001]') = 09/19/2013

format-dateTime(current-dateTime(), '[h1]:[m01] [P] on [MNn] [D].') = 9:26 a.m. on September 19.

The part you're missing is converting from the integer to the type-safe enum. Java will not do it automatically. There's a couple of ways you can go about this:

1. Use a list of static final ints rather than a type-safe enum and switch on the int value you receive (this is the pre-Java 5 approach)
2. Switch on either a specified id value (as described by heneryville) or the ordinal value of the enum values; i.e. guideView.GUIDE_VIEW_SEVEN_DAY.ordinal()

3. Determine the enum value represented by the int value and then switch on the enum value.

   enum GuideView {
       SEVEN_DAY,
       NOW_SHOWING,
       ALL_TIMESLOTS
   }
   
   // Working on the assumption that your int value is 
   // the ordinal value of the items in your enum
   public void onClick(DialogInterface dialog, int which) {
       // do your own bounds checking
       GuideView whichView = GuideView.values()[which];
       switch (whichView) {
           case SEVEN_DAY:
               ...
               break;
           case NOW_SHOWING:
               ...
               break;
       }
   }
   

   You may find it more helpful / less error prone to write a custom valueOf implementation that takes your integer values as an argument to resolve the appropriate enum value and lets you centralize your bounds checking.

Try to set

this.MinimumSize = new Size(140, 480);
this.MaximumSize = new Size(140, 480);

One of the numerous niceties of Ruby is the possibility to extend existing classes with your own methods. That's called "class reopening" or monkey-patching (the meaning of the latter can vary, though).

So, take a look here:

car = {:make => "bmw", :year => "2003"}
# => {:make=>"bmw", :year=>"2003"}
car.to_json
# NoMethodError: undefined method `to_json' for {:make=>"bmw", :year=>"2003"}:Hash
#   from (irb):11
#   from /usr/bin/irb:12:in `<main>'
require 'json'
# => true
car.to_json
# => "{"make":"bmw","year":"2003"}"

As you can see, requiring json has magically brought method to_json to our Hash.

element.children().first();

Find all children and get first of them.

Check if string is positive digit (integer) and alphabet

You may use str.isdigit() and str.isalpha() to check whether given string is positive integer and alphabet respectively.

Sample Results:

# For alphabet
>>> 'A'.isdigit()
False
>>> 'A'.isalpha()
True

# For digit
>>> '1'.isdigit()
True
>>> '1'.isalpha()
False

Check for strings as positive/negative - integer/float

str.isdigit() returns False if the string is a negative number or a float number. For example:

# returns `False` for float
>>> '123.3'.isdigit()
False
# returns `False` for negative number
>>> '-123'.isdigit()
False

If you want to also check for the negative integers and float, then you may write a custom function to check for it as:

def is_number(n):
    try:
        float(n)   # Type-casting the string to `float`.
                   # If string is not a valid `float`, 
                   # it'll raise `ValueError` exception
    except ValueError:
        return False
    return True

Sample Run:

>>> is_number('123')    # positive integer number
True

>>> is_number('123.4')  # positive float number
True
 
>>> is_number('-123')   # negative integer number
True

>>> is_number('-123.4') # negative `float` number
True

>>> is_number('abc')    # `False` for "some random" string
False

Discard "NaN" (not a number) strings while checking for number

The above functions will return True for the "NAN" (Not a number) string because for Python it is valid float representing it is not a number. For example:

>>> is_number('NaN')
True

In order to check whether the number is "NaN", you may use math.isnan() as:

>>> import math
>>> nan_num = float('nan')

>>> math.isnan(nan_num)
True

Or if you don't want to import additional library to check this, then you may simply check it via comparing it with itself using ==. Python returns False when nan float is compared with itself. For example:

# `nan_num` variable is taken from above example
>>> nan_num == nan_num
False

Hence, above function is_number can be updated to return False for "NaN" as:

def is_number(n):
    is_number = True
    try:
        num = float(n)
        # check for "nan" floats
        is_number = num == num   # or use `math.isnan(num)`
    except ValueError:
        is_number = False
    return is_number

Sample Run:

>>> is_number('Nan')   # not a number "Nan" string
False

>>> is_number('nan')   # not a number string "nan" with all lower cased
False

>>> is_number('123')   # positive integer
True

>>> is_number('-123')  # negative integer
True

>>> is_number('-1.12') # negative `float`
True

>>> is_number('abc')   # "some random" string
False

Allow Complex Number like "1+2j" to be treated as valid number

The above function will still return you False for the complex numbers. If you want your is_number function to treat complex numbers as valid number, then you need to type cast your passed string to complex() instead of float(). Then your is_number function will look like:

def is_number(n):
    is_number = True
    try:
        #      v type-casting the number here as `complex`, instead of `float`
        num = complex(n)
        is_number = num == num
    except ValueError:
        is_number = False
    return is_number

Sample Run:

>>> is_number('1+2j')    # Valid 
True                     #      : complex number 

>>> is_number('1+ 2j')   # Invalid 
False                    #      : string with space in complex number represetantion
                         #        is treated as invalid complex number

>>> is_number('123')     # Valid
True                     #      : positive integer

>>> is_number('-123')    # Valid 
True                     #      : negative integer

>>> is_number('abc')     # Invalid 
False                    #      : some random string, not a valid number

>>> is_number('nan')     # Invalid
False                    #      : not a number "nan" string

PS: Each operation for each check depending on the type of number comes with additional overhead. Choose the version of is_number function which fits your requirement.

I wanted something to return the address regardless of whether or not wifi was enabled, so the chosen solution didn't work for me. I used another call I found on some forum after some tweaking. I ended up with the following (excuse my rusty C ) :

#include <sys/types.h>
#include <stdio.h>
#include <string.h>
#include <sys/socket.h>
#include <net/if_dl.h>
#include <ifaddrs.h>


char*  getMacAddress(char* macAddress, char* ifName) {

int  success;
struct ifaddrs * addrs;
struct ifaddrs * cursor;
const struct sockaddr_dl * dlAddr;
const unsigned char* base;
int i;

success = getifaddrs(&addrs) == 0;
if (success) {
    cursor = addrs;
    while (cursor != 0) {
        if ( (cursor->ifa_addr->sa_family == AF_LINK)
            && (((const struct sockaddr_dl *) cursor->ifa_addr)->sdl_type == IFT_ETHER) && strcmp(ifName,  cursor->ifa_name)==0 ) {
            dlAddr = (const struct sockaddr_dl *) cursor->ifa_addr;
            base = (const unsigned char*) &dlAddr->sdl_data[dlAddr->sdl_nlen];
            strcpy(macAddress, ""); 
            for (i = 0; i < dlAddr->sdl_alen; i++) {
                if (i != 0) {
                    strcat(macAddress, ":");
                }
                char partialAddr[3];
                sprintf(partialAddr, "%02X", base[i]);
                strcat(macAddress, partialAddr);

            }
        }
        cursor = cursor->ifa_next;
    }

    freeifaddrs(addrs);
}    
return macAddress;
}

And then I would call it asking for en0, as follows:

char* macAddressString= (char*)malloc(18);
NSString* macAddress= [[NSString alloc] initWithCString:getMacAddress(macAddressString, "en0")
                                              encoding:NSMacOSRomanStringEncoding];
free(macAddressString);

If you aren't actually restricted to keeping all of these elements as sibling nodes you can wrap the ones that go together in another default flex box, and have the container of both use space-between.

.space-between {_x000D_
  border: 1px solid red;_x000D_
  display: flex;_x000D_
  justify-content: space-between;_x000D_
}_x000D_
.default-flex {_x000D_
  border: 1px solid blue;_x000D_
  display: flex;_x000D_
}_x000D_
.child {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  border: 1px solid;_x000D_
}

<div class="space-between">_x000D_
  <div class="child">1</div>_x000D_
  <div class="default-flex">_x000D_
    <div class="child">2</div>_x000D_
    <div class="child">3</div>_x000D_
    <div class="child">4</div>_x000D_
    <div class="child">5</div>_x000D_
  </div>_x000D_
</div>

Or if you were doing the same thing with flex-start and flex-end reversed you just swap the order of the default-flex container and lone child.

This will be possible in C# 6.0:

public int Y { get; } = 2;

You could use Kernel#test:

test ?d, 'some directory'

it gets it's origins from https://ss64.com/bash/test.html you will notice bash test has this flag -d to test if a directory exists -d file True if file is a Directory. [[ -d demofile ]]

OP asked about running from node not from mocha. This is a very common use case, see Using Mocha Programatically

This is what injected describe and it into my tests.

mocha.ui('bdd').run(function (failures) {
    process.on('exit', function () {
      process.exit(failures);
    });
  });

I tried tdd like in the docs, but that didn't work, bdd worked though.

According to Property Accessors defined in ECMA-262(http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-262.pdf, P67), there are two ways you can do to add properties to a exists object. All these two way, the Javascript engine will treat them the same.

The first way is to use dot notation:

obj.key3 = value3;

But this way, you should use a IdentifierName after dot notation.

The second way is to use bracket notation:

obj["key3"] = value3;

and another form:

var key3 = "key3";
obj[key3] = value3;

This way, you could use a Expression (include IdentifierName) in the bracket notation.

Using ReactiveUI, I've created the following alternate solution. It's not an elegant all-in-one solution, but I think at the very least it's readable.

In my case, binding a list of enum to a control is a rare case, so I don't need to scale the solution across the code base. However, the code can be made more generic by changing EffectStyleLookup.Item into an Object. I tested it with my code, no other modifications are necessary. Which means the one helper class could be applied to any enum list. Though that would reduce its readability - ReactiveList<EnumLookupHelper> doesn't have a great ring to it.

Using the following helper class:

public class EffectStyleLookup
{
    public EffectStyle Item { get; set; }
    public string Display { get; set; }
}

In the ViewModel, convert the list of enums and expose it as a property:

public ViewModel : ReactiveObject
{
  private ReactiveList<EffectStyleLookup> _effectStyles;
  public ReactiveList<EffectStyleLookup> EffectStyles
  {
    get { return _effectStyles; }
    set { this.RaiseAndSetIfChanged(ref _effectStyles, value); }
  }

  // See below for more on this
  private EffectStyle _selectedEffectStyle;
  public EffectStyle SelectedEffectStyle
  {
    get { return _selectedEffectStyle; }
    set { this.RaiseAndSetIfChanged(ref _selectedEffectStyle, value); }
  }

  public ViewModel() 
  {
    // Convert a list of enums into a ReactiveList
    var list = (IList<EffectStyle>)Enum.GetValues(typeof(EffectStyle))
      .Select( x => new EffectStyleLookup() { 
        Item = x, 
        Display = x.ToString()
      });

    EffectStyles = new ReactiveList<EffectStyle>( list );
  }
}

In the ComboBox, utilise the SelectedValuePath property, to bind to the original enum value:

<ComboBox Name="EffectStyle" DisplayMemberPath="Display" SelectedValuePath="Item" />

In the View, this allows us to bind the original enum to the SelectedEffectStyle in the ViewModel, but display the ToString() value in the ComboBox:

this.WhenActivated( d =>
{
  d( this.OneWayBind(ViewModel, vm => vm.EffectStyles, v => v.EffectStyle.ItemsSource) );
  d( this.Bind(ViewModel, vm => vm.SelectedEffectStyle, v => v.EffectStyle.SelectedValue) );
});

Try the following (Which does not print -1 at the end now!)

int index = word.indexOf(guess);
while(index >= 0) {
   System.out.println(index);
   index = word.indexOf(guess, index+1);
}

You simply call

Blog::all();

//example usage.
$posts = Blog::all();

$posts->each(function($post) // foreach($posts as $post) { }
{
    //do something
}

from anywhere in your application.

Reading the documentation will help a lot.

You should put your processing into the class constructor or an OnInit hook method.

I think there are two different things here. The first one is that normal SSH authentication requires the user to put the account's password (where the account password will be authenticated against different methods, depending on the sshd configuration).

You can avoid putting that password using certificates. With certificates you still have to put a password, but this time is the password of your private key (that's independent of the account's password).

To do this you can follow the instructions pointed out by steveth45:

With Public Key Authentication.

If you want to avoid putting the certificate's password every time then you can use ssh-agent, as pointed out by DigitalRoss

The exact way you do this depends on Unix vs Windows, but essentially you need to run ssh-agent in the background when you log in, and then the first time you log in, run ssh-add to give the agent your passphrase. All ssh-family commands will then consult the agent and automatically pick up your passphrase.

Start here: man ssh-agent.

The only problem of ssh-agent is that, on *nix at least, you have to put the certificates password on every new shell. And then the certificate is "loaded" and you can use it to authenticate against an ssh server without putting any kind of password. But this is on that particular shell.

With keychain you can do the same thing as ssh-agent but "system-wide". Once you turn on your computer, you open a shell and put the password of the certificate. And then, every other shell will use that "loaded" certificate and your password will never be asked again until you restart your PC.

Gnome has a similar application, called Gnome Keyring that asks for your certificate's password the first time you use it and then it stores it securely so you won't be asked again.

Using refs is not best practice because it reads the DOM directly, it's better to use React's state instead. Also, your button doesn't change because the component is not re-rendered and stays in its initial state.

You can use setState together with an onChange event listener to render the component again every time the input field changes:

// Input field listens to change, updates React's state and re-renders the component.
<input onChange={e => this.setState({ value: e.target.value })} value={this.state.value} />

// Button is disabled when input state is empty.
<button disabled={!this.state.value} />

Here's a working example:

class AddItem extends React.Component {_x000D_
  constructor() {_x000D_
    super();_x000D_
    this.state = { value: '' };_x000D_
    this.onChange = this.onChange.bind(this);_x000D_
    this.add = this.add.bind(this);_x000D_

_x000D_
  onChange(e) {_x000D_
    this.setState({ value: e.target.value });_x000D_

_x000D_
  render() {_x000D_

You need to use the fn:contains() or fn:containsIgnoreCase() function.

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>

...

 <c:if test="${not fn:containsIgnoreCase(mylist, 'apple')}">
        <p>Doesn't contain 'apple'</p>
    </c:if>

or

<c:if test="${not fn:contains(mylist, 'Apple')}">
            <p>Contains 'Apple'</p>
        </c:if>

Note: This will work like mylist.toString().contains("apple") and if this is not what you are looking for better use a other approach.

You have compiled your code with references to the correct math.h header file, but when you attempted to link it, you forgot the option to include the math library. As a result, you can compile your .o object files, but not build your executable.

As Paul has already mentioned add "-lm" to link with the math library in the step where you are attempting to generate your executable.

In the comment, linuxD asks:

Why for sin() in <math.h>, do we need -lm option explicitly; but, not for printf() in <stdio.h>?

Because both these functions are implemented as part of the "Single UNIX Specification". This history of this standard is interesting, and is known by many names (IEEE Std 1003.1, X/Open Portability Guide, POSIX, Spec 1170).

This standard, specifically separates out the "Standard C library" routines from the "Standard C Mathematical Library" routines (page 277). The pertinent passage is copied below:

Standard C Library

The Standard C library is automatically searched by cc to resolve external references. This library supports all of the interfaces of the Base System, as defined in Volume 1, except for the Math Routines.

Standard C Mathematical Library

This library supports the Base System math routines, as defined in Volume 1. The cc option -lm is used to search this library.

The reasoning behind this separation was influenced by a number of factors:

1. The UNIX wars led to increasing divergence from the original AT&T UNIX offering.
2. The number of UNIX platforms added difficulty in developing software for the operating system.
3. An attempt to define the lowest common denominator for software developers was launched, called 1988 POSIX.
4. Software developers programmed against the POSIX standard to provide their software on "POSIX compliant systems" in order to reach more platforms.
5. UNIX customers demanded "POSIX compliant" UNIX systems to run the software.

The pressures that fed into the decision to put -lm in a different library probably included, but are not limited to:

1. It seems like a good way to keep the size of libc down, as many applications don't use functions embedded in the math library.
2. It provides flexibility in math library implementation, where some math libraries rely on larger embedded lookup tables while others may rely on smaller lookup tables (computing solutions).
3. For truly size constrained applications, it permits reimplementations of the math library in a non-standard way (like pulling out just sin() and putting it in a custom built library.

In any case, it is now part of the standard to not be automatically included as part of the C language, and that's why you must add -lm.

You could use Map to make higher abstraction on instance of

private final Map<Class, Consumer<String>> actions = new HashMap<>();

Then having such map add some action to it:

actions.put(String.class, new Consumer<String>() {
        @Override
        public void accept(String s) {
           System.out.println("action for String");       
        }
    };

Then having an Object of not known type you could get specific action from that map:

actions.get(someObject).accept(someObject)

You could just split the frontend and backend. The frontend is hosted on the customers server with an API that makes calls to the backend on your server. This keeps all of the proprietary code proprietary and forces users to sign up / pay for subscriptions.

Here's a short answer

x=' ';

This will print one white space

print(x); 

This will print 10 white spaces

print(10*x) 

Print 10 whites spaces between Hello & World

print("Hello"+10*x+"world"); 

Just to emphasize what Tomasz Gandor and Domain said about having the right version of svn and that it was compiled to enable plain text password storage, you need verify what you have:

svn --version
svn, version 1.9.7 (r1800392)
...
WARNING: Plaintext password storage is enabled!
...

The following authentication credential caches are available:

* Plaintext cache in /gr/home/ffvdqb/.subversion
* GPG-Agent

Versus:

svn --version
svn, version 1.12.2 (r1863366)
...

The following authentication credential caches are available:

* Gnome Keyring
* GPG-Agent
* KWallet (KDE)

Once you see that your version of svn was enabled for plain text password storage, then apply all the rest of the answers here.

Note: Not supported in all browsers.

I was looking for a way to download a file using jquery without having to set the file url in the href attribute from the beginning.

jQuery('<a/>', {_x000D_
    id: 'downloadFile',_x000D_
    href: 'http://cdn.sstatic.net/Sites/stackoverflow/img/[email protected]',_x000D_
    style: 'display:hidden;',_x000D_
    download: ''_x000D_
}).appendTo('body');_x000D_
_x000D_
$("#downloadFile")[0].click();

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

This will ensure that the content gets save when you lose focus of the textarea

 setup: function (editor) {
                editor.on('change', function () {
                    tinymce.triggerSave();
                });

My use case is simpler, and fits simply your title but not your further detail.

That is, I want to install a new package which is not yet in my composer.json without updating all the other packages.

The solution here is composer require x/y

UDP is not "safe", so the question is not great - however -

• if you are on a Mac the max size you can send by default is 9216 bytes.
• if you are on Linux (CentOS/RedHat) or Windows 7 the max is 65507 bytes.

If you send 9217 or more (mac) or 65508+ (linux/windows), the socket send function returns with an error.

The above answers discussing fragmentation and MTU and so on are off topic - that all takes place at a lower level, is "invisible" to you, and does not affect "safety" on typical connections to a significant degree.

To answer the actual question meaning though - do not use UDP - use raw sockets so you get better control of everything; since you're writing a game, you need to delve into the flags to get priority into your traffic anyhow, so you may as well get rid of UDP issues at the same time.

From the errors, it would appear that the FacebookSDK.framework already includes the Bolts.framework classes. Try removing the additional Bolts.framework from the project.

No need to create custom walker. Just use additional argument and set filter for nav_menu_css_class.

For example:

$args = array(
    'container'     => '',
    'theme_location'=> 'your-theme-loc',
    'depth'         => 1,
    'fallback_cb'   => false,
    'add_li_class'  => 'your-class-name1 your-class-name-2'
    );
wp_nav_menu($args);

Notice the new 'add_li_class' argument.

And set the filter on functions.php

function add_additional_class_on_li($classes, $item, $args) {
    if(isset($args->add_li_class)) {
        $classes[] = $args->add_li_class;
    }
    return $classes;
}
add_filter('nav_menu_css_class', 'add_additional_class_on_li', 1, 3);

I just use tops:

find . -name '*.[c|cc|cp|cpp|m|mm|h]' -print0 |  xargs -0 tops -verbose  replace "verify_noerr(<b args>)" with "__Verify_noErr(<args>)" \
replace "check(<b args>)" with "__Check(<args>)" 

Most of the cases issue is due to problem with hostname . Please check the hostname ,some times database team will maintain many hostname for connecting same database . Please check with database team regarding this connection issue.

Op later stated they were using Apache Commons HttpClient 3.0.1

 HttpClient client = new HttpClient();
        client.getHttpConnectionManager().getParams().setConnectionTimeout(5000);
        client.getHttpConnectionManager().getParams().setSoTimeout(5000);

I usually go with the first two options. I've seen a scenario when the third option was used, when radio choices where embedded in labels and the css contained something like

label input {
    vertical-align: bottom;
}

in order to ensure proper vertical alignment for the radios.

I wrote a package named Pretty Slice. You can use it to visualize slices, and their backing arrays, etc.

package main

import pretty "github.com/inancgumus/prettyslice"

func main() {
    nums := []int{1, 9, 5, 6, 4, 8}
    odds := nums[:3]
    evens := nums[3:]

    nums[1], nums[3] = 9, 6
    pretty.Show("nums", nums)
    pretty.Show("odds : nums[:3]", odds)
    pretty.Show("evens: nums[3:]", evens)
}

This code is going produce and output like this one:

$rootScope basically functions as an event listener and dispatcher.

To answer the question of how it is used, it used in conjunction with rootScope.$on;

$rootScope.$broadcast("hi");

$rootScope.$on("hi", function(){
    //do something
});

However, it is a bad practice to use $rootScope as your own app's general event service, since you will quickly end up in a situation where every app depends on $rootScope, and you do not know what components are listening to what events.

The best practice is to create a service for each custom event you want to listen to or broadcast.

.service("hiEventService",function($rootScope) {
    this.broadcast = function() {$rootScope.$broadcast("hi")}
    this.listen = function(callback) {$rootScope.$on("hi",callback)}
})

First set path of python https://stackoverflow.com/questions/3701646/how-to-add-to-the-pythonpath-in-windows

For the datatype Double to int, you can use the following:

Double double = 5.00;

int integer = double.intValue();

You should set property file name without .properties extension, it works correctly for me:)

Just in case...simply trying one more time worked for me. It could just be a temporary connection issue.

A query of type MyEntity is going to return MyEntity. You want a query for a Long.

CriteriaBuilder qb = entityManager.getCriteriaBuilder();
CriteriaQuery<Long> cq = qb.createQuery(Long.class);
cq.select(qb.count(cq.from(MyEntity.class)));
cq.where(/*your stuff*/);
return entityManager.createQuery(cq).getSingleResult();

Obviously you will want to build up your expression with whatever restrictions and groupings etc you skipped in the example.

hasOwnProperty expects the property name as a string, so it would be shape1.hasOwnProperty("name")

In my case the problem was using the language tag "en_US" in Locale.forLanguageTag(..) instead of "en-US" - use a dash instead of underline!

Also use Locale.forLanguageTag("en-US") instead of new Locale("en_US") or new Locale("en_US") to define a language ("en") with a region ("US") - but new Locale("en") works.

The repartition algorithm does a full shuffle of the data and creates equal sized partitions of data. coalesce combines existing partitions to avoid a full shuffle.

Coalesce works well for taking an RDD with a lot of partitions and combining partitions on a single worker node to produce a final RDD with less partitions.

Repartition will reshuffle the data in your RDD to produce the final number of partitions you request. The partitioning of DataFrames seems like a low level implementation detail that should be managed by the framework, but it’s not. When filtering large DataFrames into smaller ones, you should almost always repartition the data. You’ll probably be filtering large DataFrames into smaller ones frequently, so get used to repartitioning.

Read this blog post if you'd like even more details.

I've developed a small vagrant-address plugin for that. It's simple, cross-platform, cross-provider, and does not require scripting.

https://github.com/mkuzmin/vagrant-address

Assuming your div has an id="myDiv", add the following to your CSS. The cursor: pointer specifies that the cursor should be the same hand icon that is use for anchors (hyperlinks):

CSS to Add

#myDiv
{
    cursor: pointer;
}

You can simply add the cursor style to your div's HTML like this:

<div style="cursor: pointer">

</div>

EDIT:

If you are determined to use jQuery for this, then add the following line to your $(document).ready() or body onload: (replace myClass with whatever class all of your divs share)

$('.myClass').css('cursor', 'pointer');

I think this is helpful for you

I encountered similar issue when uploading a file returned 409.

Besides issues mentioned above it can also happen due to file size restrictions for POST on the server side. For example, tomcat (java web server) have POST size limit of 2MB by default.

The selector criteria is now an attribute the DIV tag.

examples are ...

data-date-format="dd MM yyyy" 
data-date-format="dd MM yyyy - HH:ii p
data-date-format="hh:ii"

so the bootstrap example for dd mm yyyy is:-

<div class="input-group date form_date col-md-5" data-date="" 
    data-date-format="dd MM yyyy" data-link-field="dtp_input2" data-link-format="yyyy-mm-dd">
..... etc ....
</div>

my Javascript settings are as follows:-

            var picker_settings = {
                language:  'en',
                weekStart: 1,
                todayBtn:  1,
                autoclose: 1,
                todayHighlight: 1,
                startView: 2,
                minView: 2,
                forceParse: 0
            };

        $(datePickerId).datetimepicker(picker_settings);

You can see working examples of these if you download the bootstrap-datetimepicker-master file. There are sample folders each with an index.html.

We can add "AwaitTerminationSeconds" property for both taskExecutor and taskScheduler as below,

<property name="awaitTerminationSeconds" value="${taskExecutor .awaitTerminationSeconds}" />

<property name="awaitTerminationSeconds" value="${taskScheduler .awaitTerminationSeconds}" />

Documentation for "waitForTasksToCompleteOnShutdown" property says, when shutdown is called

"Spring's container shutdown continues while ongoing tasks are being completed. If you want this executor to block and wait for the termination of tasks before the rest of the container continues to shut down - e.g. in order to keep up other resources that your tasks may need -, set the "awaitTerminationSeconds" property instead of or in addition to this property."

https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/scheduling/concurrent/ExecutorConfigurationSupport.html#setWaitForTasksToCompleteOnShutdown-boolean-

So it is always advised to use waitForTasksToCompleteOnShutdown and awaitTerminationSeconds properties together. Value of awaitTerminationSeconds depends on our application.

Dirty fix.

android:paddingTop="10dp"
android:drawableTop="@drawable/ic_src"

Figuring right padding solve the purpose. However, for varied screen, use different padding and put that in dimens resource in respective value folder.

I had problem with encoding cyrillic letters to URF-8.

I modified one of the above scripts to match cyrillic char map. Implmented is the cyrrilic section of

https://en.wikipedia.org/wiki/UTF-8 and http://www.utf8-chartable.de/unicode-utf8-table.pl?start=1024

Good luck!

For me, the object definitely existed and was uploaded correctly, however, its s3 url still threw the same error:

<Code>NoSuchKey</Code>
<Message>The specified key does not exist.</Message>

I found out that the reason was because my filename contained a # symbol, and I guess certain characters or symbols will also cause this error.

Removing this character and generating the new s3 url resolved my issue.

Or use PyInstaller as an alternative to py2exe. Here is a good starting point. PyInstaller also lets you create executables for linux and mac...

Here is how one could fairly easily use PyInstaller to solve the issue at hand:

pyinstaller oldlogs.py

From the tool's documentation:

PyInstaller analyzes myscript.py and:

• Writes myscript.spec in the same folder as the script.
• Creates a folder build in the same folder as the script if it does not exist.
• Writes some log files and working files in the build folder.
• Creates a folder dist in the same folder as the script if it does not exist.
• Writes the myscript executable folder in the dist folder.

In the dist folder you find the bundled app you distribute to your users.

public static void main(String[] args) {
    try {
        String ss = null;
        Process p = Runtime.getRuntime().exec("cmd.exe /c start dir ");
        BufferedWriter writeer = new BufferedWriter(new OutputStreamWriter(p.getOutputStream()));
        writeer.write("dir");
        writeer.flush();
        BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
        BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
        System.out.println("Here is the standard output of the command:\n");
        while ((ss = stdInput.readLine()) != null) {
            System.out.println(ss);
        }
        System.out.println("Here is the standard error of the command (if any):\n");
        while ((ss = stdError.readLine()) != null) {
            System.out.println(ss);
        }

    } catch (IOException e) {
        System.out.println("FROM CATCH" + e.toString());
    }

}

Does your cacerts.pem file hold a single certificate? Since it is a PEM, have a look at it (with a text editor), it should start with

-----BEGIN CERTIFICATE-----

and end with

-----END CERTIFICATE-----

Finally, to check it is not corrupted, get hold of openssl and print its details using

openssl x509 -in cacerts.pem -text

For a non-volatile solution, how about for 2007+:

for cell    =INDEX($A$1:$XFC$1048576,ROW(),COLUMN())
for column  =INDEX($A$1:$XFC$1048576,0,COLUMN())
for row     =INDEX($A$1:$XFC$1048576,ROW(),0)

I have weird bug on Excel 2010 where it won't accept the very last row or column for these formula (row 1048576 & column XFD), so you may need to reference these one short. Not sure if that's the same for any other versions so appreciate feedback and edit.

and for 2003 (INDEX became non-volatile in '97):

for cell    =INDEX($A$1:$IV$65536,ROW(),COLUMN())
for column  =INDEX($A$1:$IV$65536,0,COLUMN())
for row     =INDEX($A$1:$IV$65536,ROW(),0)

    String.prototype.endsWith = function(substring, position) {
        substring = String(substring);

        var subLen = substring.length | 0;

        if( !subLen )return true;//Empty string

        var strLen = this.length;

        if( position === void 0 )position = strLen;
        else position = position | 0;

        if( position < 1 )return false;

        var fromIndex = (strLen < position ? strLen : position) - subLen;

        return (fromIndex >= 0 || subLen === -fromIndex)
            && (
                position === 0
                // if position not at the and of the string, we can optimise search substring
                //  by checking first symbol of substring exists in search position in current string
                || this.charCodeAt(fromIndex) === substring.charCodeAt(0)//fast false
            )
            && this.indexOf(substring, fromIndex) === fromIndex
        ;
    };
}

Benefits:

• This version is not just re-using indexOf.
• Greatest performance on long strings. Here is a speed test http://jsperf.com/starts-ends-with/4
• Fully compatible with ecmascript specification. It passes the tests

Use the following command

remove(list=c("data_1", "data_2", "data_3"))

Working Query:

SELECT replace(col_name , ' ','') FROM table_name;

While this doesn't :

SELECT trim(col_name) FROM table_name;

First of all, move all your PHP code to the top. Without it, my code below wont work.

To do the redirect, use:

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

Also, please consider my advice. Since it's not the first question today and all your questions are related to basics, you should consider reading some good PHP book to understand how things work.

Here you can find useful links to free books: https://stackoverflow.com/tags/php/info

Try

ROLLBACK WORK;

It usually works

Try This

$(this).closest('.ui-dialog-content').dialog('close'); 

It will close the dialog inside it.

just try (onclick)="this.value = null"

in your html page add onclick method to remove previous value so user can select same file again.

Use conditional comments in HTML, like this:

<!--[if IE 8]>
<style>...</style>
<![endif]-->

See here: http://www.quirksmode.org/css/condcom.html

You can test for IE versions reliably and also be sure other browsers won't be confused.

Short answer:

:%s/string-to-be-searched//gn

For learning:

There are 3 modes in VI editor as below

• : you are entering from Command to Command-line mode. Now, whatever you write after : is on CLI(Command Line Interface)
• %s specifies all lines. Specifying the range as % means do substitution in the entire file. Syntax for all occurrences substitution is :%s/old-text/new-text/g
• g specifies all occurrences in the line. With the g flag , you can make the whole line to be substituted. If this g flag is not used then only first occurrence in the line only will be substituted.
• n specifies to output number of occurrences
• //double slash represents omission of replacement text. Because we just want to find.

Once got the number of occurrences, you can Press N Key to see occurrences one-by-one.

For finding and counting in particular range of line number 1 to 10:

:1,10s/hello//gn

• Please note, % for whole file is repleaced by , separated line numbers.

For finding and replacing in particular range of line number 1 to 10:

:1,10s/helo/hello/gn

In Visual Studio 2013 AND VS15 (but i guess if the same for all other version) just press F4 and change this two properties: -Anonymous Authentication: Disable -Windows Authentication: Enable

We've used a solution based on timeGetTime in winmm.dll for millisecond accuracy for many years. See http://www.aboutvb.de/kom/artikel/komstopwatch.htm

The article is in German, but the code in the download (a VBA class wrapping the dll function call) is simple enough to use and understand without being able to read the article.

Well, you can always try WHERE textcolumn LIKE "%SUBSTRING%" - but this is guaranteed to be pretty slow, as your query can't do an index match because you are looking for characters on the left side.

It depends on the field type - a textarea usually won't be saved as VARCHAR, but rather as (a kind of) TEXT field, so you can use the MATCH AGAINST operator.

To get the columns that don't match, simply put a NOT in front of the like: WHERE textcolumn NOT LIKE "%SUBSTRING%".

Whether the search is case-sensitive or not depends on how you stock the data, especially what COLLATION you use. By default, the search will be case-insensitive.

Updated answer to reflect question update:

I say that doing a WHERE field LIKE "%value%" is slower than WHERE field LIKE "value%" if the column field has an index, but this is still considerably faster than getting all values and having your application filter. Both scenario's:

1/ If you do SELECT field FROM table WHERE field LIKE "%value%", MySQL will scan the entire table, and only send the fields containing "value".

2/ If you do SELECT field FROM table and then have your application (in your case PHP) filter only the rows with "value" in it, MySQL will also scan the entire table, but send all the fields to PHP, which then has to do additional work. This is much slower than case #1.

Solution: Please do use the WHERE clause, and use EXPLAIN to see the performance.

You need to put the last() indexing on the nodelist result, rather than as part of the selection criteria. Try:

(//element[@name='D'])[last()]

The widely-used PCRE library can handle such situations (you won't achieve the the same with POSIX-compliant regex engines, though):

For copy-paste into command line:

git checkout master ; remote=origin ; for brname in `git branch -r | grep $remote | grep -v master | grep -v HEAD | awk '{gsub(/^[^\/]+\//,"",$1); print $1}'`; do git branch -D $brname ; git checkout -b $brname $remote/$brname ; done ; git checkout master

For more readibility:

git checkout master ;
remote=origin ;
for brname in `
    git branch -r | grep $remote | grep -v master | grep -v HEAD 
    | awk '{gsub(/^[^\/]+\//,"",$1); print $1}'
`; do
    git branch -D $brname ;
    git checkout -b $brname $remote/$brname ;
done ;
git checkout master

1. check out master (so that we can delete branch we are on)
2. select remote to checkout (change it to whatever remote you have)
3. loop through all branches of the remote except master and HEAD
   1. delete local branch (so that we can check out force-updated branches)
   2. check out branch from the remote
4. check out master (for the sake of it)

Based on answer of VonC.

You can use jquery Touch events. (see here)

  let holdBtn = $('#holdBtn')
  let holdDuration = 1000
  let holdTimer

  holdBtn.on('touchend', function () {
    // finish hold
  });
  holdBtn.on('touchstart', function () {
    // start hold
    holdTimer = setTimeout(function() {
      //action after certain time of hold
    }, holdDuration );
  });

Create a UITextView inside of a tableViewController. I used function: textViewDidChange and then checked for return-key-input. then if it detected return-key-input, delete the input of return key and dismiss keyboard.

func textViewDidChange(_ textView: UITextView) {
    tableView.beginUpdates()
    if textView.text.contains("\n"){
        textView.text.remove(at: textView.text.index(before: textView.text.endIndex))
        textView.resignFirstResponder()
    }
    tableView.endUpdates()
}

A Ternary is not a good solution for what you want. It will not be readable in your code, and there are much better solutions available.

Why not use an array lookup "map" or "dictionary", like so:

$vocations = array(
    1 => "Sorcerer",
    2 => "Druid",
    3 => "Paladin",
    ...
);

echo $vocations[$result->vocation];

A ternary for this application would end up looking like this:

echo($result->group_id == 1 ? "Player" : ($result->group_id == 2 ? "Gamemaster" : ($result->group_id == 3 ? "God" : "unknown")));

Why is this bad? Because - as a single long line, you would get no valid debugging information if something were to go wrong here, the length makes it difficult to read, plus the nesting of the multiple ternaries just feels odd.

A Standard Ternary is simple, easy to read, and would look like this:

$value = ($condition) ? 'Truthy Value' : 'Falsey Value';

or

echo ($some_condition) ? 'The condition is true!' : 'The condition is false.';

A ternary is really just a convenient / shorter way to write a simple if else statement. The above sample ternary is the same as:

if ($some_condition) {
    echo 'The condition is true!';
} else {
    echo 'The condition is false!';
}

However, a ternary for a complex logic quickly becomes unreadable, and is no longer worth the brevity.

echo($result->group_id == 1 ? "Player" : ($result->group_id == 2 ? "Gamemaster" : ($result->group_id == 3 ? "God" : "unknown")));

Even with some attentive formatting to spread it over multiple lines, it's not very clear:

echo($result->group_id == 1 
    ? "Player" 
    : ($result->group_id == 2 
        ? "Gamemaster" 
        : ($result->group_id == 3 
            ? "God" 
            : "unknown")));

A merge conflict occurs when two branches you're trying to merge both changed the same part of the same file. You can generate a list of conflicts with git status.

When the conflicted line is encountered, Git will edit the content of the affected files with visual indicators that mark both sides of the conflicting content.

<<<<<<< HEAD
conflicted text from HEAD
=======
conflicted text from merging_branch
>>>>>>> merging_branch

When you fix your conflicted files and you are ready to merge, all you have to do is run git add and git commit to generate the merge commit. Once the commit was made ,git push the changes to the branch.

Reference article: Git merge.

This is a very round-about way of doing it but if you want to make a histogram where you already know the bin values but dont have the source data, you can use the np.random.randint function to generate the correct number of values within the range of each bin for the hist function to graph, for example:

import numpy as np
import matplotlib.pyplot as plt

data = [np.random.randint(0, 9, *desired y value*), np.random.randint(10, 19, *desired y value*), etc..]
plt.hist(data, histtype='stepfilled', bins=[0, 10, etc..])

as for labels you can align x ticks with bins to get something like this:

#The following will align labels to the center of each bar with bin intervals of 10
plt.xticks([5, 15, etc.. ], ['Label 1', 'Label 2', etc.. ])

Another reason to use merge is when using custom viewgroups in ListViews or GridViews. Instead of using the viewHolder pattern in a list adapter, you can use a custom view. The custom view would inflate an xml whose root is a merge tag. Code for adapter:

public class GridViewAdapter extends BaseAdapter {
     // ... typical Adapter class methods
     @Override
     public View getView(int position, View convertView, ViewGroup parent) {
        WallpaperView wallpaperView;
        if (convertView == null)
           wallpaperView = new WallpaperView(activity);
        else
            wallpaperView = (WallpaperView) convertView;

        wallpaperView.loadWallpaper(wallpapers.get(position), imageWidth);
        return wallpaperView;
    }
}

here is the custom viewgroup:

public class WallpaperView extends RelativeLayout {

    public WallpaperView(Context context) {
        super(context);
        init(context);
    }
    // ... typical constructors

    private void init(Context context) {
        View.inflate(context, R.layout.wallpaper_item, this);
        imageLoader = AppController.getInstance().getImageLoader();
        imagePlaceHolder = (ImageView) findViewById(R.id.imgLoader2);
        thumbnail = (NetworkImageView) findViewById(R.id.thumbnail2);
        thumbnail.setScaleType(ImageView.ScaleType.CENTER_CROP);
    }

    public void loadWallpaper(Wallpaper wallpaper, int imageWidth) {
        // ...some logic that sets the views
    }
}

and here is the XML:

<merge xmlns:android="http://schemas.android.com/apk/res/android">

    <ImageView
        android:id="@+id/imgLoader"
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:layout_centerInParent="true"
        android:src="@drawable/ico_loader" />

    <com.android.volley.toolbox.NetworkImageView
        android:id="@+id/thumbnail"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</merge>

i think this can be as simple let as assume that you are going to pass multiple parameters to you action as you read up there actions accept only two parameters context and payload which is your data you want to pass in action so let take an example

Setting up Action

instead of

actions: {
        authenticate: ({ commit }, token, expiration) => commit('authenticate', token, expiration)
    }

do

actions: {
        authenticate: ({ commit }, {token, expiration}) => commit('authenticate', token, expiration)
    }

Calling (dispatching) Action

instead of

this.$store.dispatch({
                  type: 'authenticate',
                  token: response.body.access_token,
                  expiration: response.body.expires_in + Date.now()
              })

do

this.$store.dispatch('authenticate',{
                  token: response.body.access_token,
                  expiration: response.body.expires_in + Date.now()
              })

hope this gonna help

I believe Stefan's answer is right on. If you want to remove only one node (rather than all matching nodes), here is another example:

//Load XML from file (or it could come from a POST, etc.)
$xml = simplexml_load_file('fileName.xml');

//Use XPath to find target node for removal
$target = $xml->xpath("//seg[@id=$uniqueIdToDelete]");

//If target does not exist (already deleted by someone/thing else), halt
if(!$target)
return; //Returns null

//Import simpleXml reference into Dom & do removal (removal occurs in simpleXML object)
$domRef = dom_import_simplexml($target[0]); //Select position 0 in XPath array
$domRef->parentNode->removeChild($domRef);

//Format XML to save indented tree rather than one line and save
$dom = new DOMDocument('1.0');
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
$dom->loadXML($xml->asXML());
$dom->save('fileName.xml');

Note that sections Load XML... (first) and Format XML... (last) could be replaced with different code depending on where your XML data comes from and what you want to do with the output; it is the sections in between that find a node and remove it.

In addition, the if statement is only there to ensure that the target node exists before trying to move it. You could choose different ways to handle or ignore this case.

Here is my Timer widget, not related to the Question but may help someone.

import 'dart:async';

import 'package:flutter/material.dart';

class OtpTimer extends StatefulWidget {
  @override
  _OtpTimerState createState() => _OtpTimerState();
}

class _OtpTimerState extends State<OtpTimer> {
  final interval = const Duration(seconds: 1);

  final int timerMaxSeconds = 60;

  int currentSeconds = 0;

  String get timerText =>
      '${((timerMaxSeconds - currentSeconds) ~/ 60).toString().padLeft(2, '0')}: ${((timerMaxSeconds - currentSeconds) % 60).toString().padLeft(2, '0')}';

  startTimeout([int milliseconds]) {
    var duration = interval;
    Timer.periodic(duration, (timer) {
      setState(() {
        print(timer.tick);
        currentSeconds = timer.tick;
        if (timer.tick >= timerMaxSeconds) timer.cancel();
      });
    });
  }

  @override
  void initState() {
    startTimeout();
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Row(
      mainAxisSize: MainAxisSize.min,
      children: <Widget>[
        Icon(Icons.timer),
        SizedBox(
          width: 5,
        ),
        Text(timerText)
      ],
    );
  }
}

You will get something like this

Just use /\s+/ against '' as a splitter. In this case all "extra" blanks were removed. Usually this particular behaviour is required. So, in you case it will be:

my $line = "file1.gz file1.gz file3.gz";
my @abc = split(/\s+/, $line);

See here if you want to grant a Facebook App permanent access to a page (even when you / the app owner are logged out):

http://developers.facebook.com/docs/opengraph/using-app-tokens/

"An App Access Token does not expire unless you refresh the application secret through your app settings."

Looks like you're using SQL Server, in which case GETDATE() or current_timestamp may help you. But you will have to ensure that the format of the date with which you are comparing the system dates matches (timezone, granularity etc.)

e.g.

where convert(varchar(10), submission_date, 102) 
    = convert(varchar(10), getdate(), 102)

For those who struggle at capturing Enter key on TextBox or other input control, if your Form has AcceptButton defined, you will not be able to use KeyDown event to capture Enter.

What you should do is to catch the Enter key at form level. Add this code to the form:

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
    if ((this.ActiveControl == myTextBox) && (keyData == Keys.Return))
    {
        //do something
        return true;
    }
    else
    {
        return base.ProcessCmdKey(ref msg, keyData);
    }
}

What you are looking for can be found here. It may exist a more elegant way to accomplish that, but one possible approach is

Option 1 (preferred):

final Duration timeout = Duration.ofSeconds(30);
ExecutorService executor = Executors.newSingleThreadExecutor();

final Future<String> handler = executor.submit(new Callable() {
    @Override
    public String call() throws Exception {
        return requestDataFromModem();
    }
});

try {
    handler.get(timeout.toMillis(), TimeUnit.MILLISECONDS);
} catch (TimeoutException e) {
    handler.cancel(true);
}

executor.shutdownNow();

Option 2:

final Duration timeout = Duration.ofSeconds(30);
ScheduledExecutorService executor = Executors.newScheduledThreadPool(1);

final Future<String> handler = executor.submit(new Callable() {
    @Override
    public String call() throws Exception {
        return requestDataFromModem();
    }
});

executor.schedule(new Runnable() {
    @Override
    public void run(){
        handler.cancel(true);
    }      
}, timeout.toMillis(), TimeUnit.MILLISECONDS);

executor.shutdownNow();

Those are only a draft so that you can get the main idea.

You can try this:

select
  count(distinct tag) as tag_count,
  count(distinct (case when entryId > 0 then tag end)) as positive_tag_count
from
  your_table_name;

The first count(distinct...) is easy. The second one, looks somewhat complex, is actually the same as the first one, except that you use case...when clause. In the case...when clause, you filter only positive values. Zeros or negative values would be evaluated as null and won't be included in count.

One thing to note here is that this can be done by reading the table once. When it seems that you have to read the same table twice or more, it can actually be done by reading once, in most of the time. As a result, it will finish the task a lot faster with less I/O.

If you need to add multiple key=>value, then try this.

$data = array_merge($data, array("cat"=>"wagon","foo"=>"baar"));

I think you can use db.collection.distinct(fields,query)

You will be able to get the distinct values in your case for NetworkID.

It should be something like this :

Db.collection.distinct('NetworkID')

After using all these mentioned solution, i was still not able to scroll using mouse scroll, keyboard up/down button were working for scrolling content.

So i have added below css fixes to make it working

.modal-open {
    overflow: hidden;
}

.modal-open .modal {
    overflow-x: hidden;
    overflow-y: auto;
    **pointer-events: auto;**
}

Added pointer-events: auto; to make it mouse scrollable.

You can use import nbimporter then import notebookName

A linked table row is possible, but not with the standard <table> elements. You can do it using the display: table style properties. Here and here are some fiddles to demonstrate.

This code should do the trick:

.table {_x000D_
  display: table;_x000D_
}_x000D_
_x000D_
.row {_x000D_
  display: table-row;_x000D_
}_x000D_
_x000D_
.cell {_x000D_
  display: table-cell;_x000D_
  padding: 10px;_x000D_
}_x000D_
_x000D_
.row:hover {_x000D_

}

Note that ARIA roles are needed to ensure proper accessibility since the standard <table> elements are not used. You may need to add additional roles like role="columnheader" if applicable. Find out more at the guide here.

[label setNumberOfLines:1];//Set number of lines in label.
[label.layer setCornerRadius:25.0];//Set corner radius of label to change the shape.
[label.layer setBorderWidth:2.0f];//Set border width of label.
[label setClipsToBounds:YES];//Set its to YES for Corner radius to work.
[label.layer setBorderColor:[UIColor blackColor].CGColor];//Set Border color.
[self.view addSubview:label];//Add it to the view of your choice. 

Application Server:

Application server maintains the application logic and
serves the web pages in response to user request.

That means application server can do both application logic maintanence and web page serving.

Web Server:

Web server just serves the web pages and it cannot enforce any application logic.

Final conclusion is: Application server also contains the web server.

Use the css property overflow . For example:

  .item{
    width : 100px;
    overflow:hidden;
  }

The overflow property can have one of many values like ( hidden , scroll , visible ) .. you can als control the overflow in one direction only using overflow-x or overflow-y.

I hope this helps.

See this link http://momentjs.com/docs/#/displaying/unix-timestamp-milliseconds/

valueOf() is the function you're looking for.

Editing my answer (OP wants milliseconds of today, not since epoch)

You want the milliseconds() function OR you could go the route of moment().valueOf()

Imperative ? declarative

In jQuery, selectors are used to find DOM elements and then bind/register event handlers to them. When an event triggers, that (imperative) code executes to update/change the DOM.

In AngularJS, you want to think about views rather than DOM elements. Views are (declarative) HTML that contain AngularJS directives. Directives set up the event handlers behind the scenes for us and give us dynamic databinding. Selectors are rarely used, so the need for IDs (and some types of classes) is greatly diminished. Views are tied to models (via scopes). Views are a projection of the model. Events change models (that is, data, scope properties), and the views that project those models update "automatically."

In AngularJS, think about models, rather than jQuery-selected DOM elements that hold your data. Think about views as projections of those models, rather than registering callbacks to manipulate what the user sees.

Separation of concerns

jQuery employs unobtrusive JavaScript - behavior (JavaScript) is separated from the structure (HTML).

AngularJS uses controllers and directives (each of which can have their own controller, and/or compile and linking functions) to remove behavior from the view/structure (HTML). Angular also has services and filters to help separate/organize your application.

See also https://stackoverflow.com/a/14346528/215945

Application design

One approach to designing an AngularJS application:

1. Think about your models. Create services or your own JavaScript objects for those models.
2. Think about how you want to present your models -- your views. Create HTML templates for each view, using the necessary directives to get dynamic databinding.
3. Attach a controller to each view (using ng-view and routing, or ng-controller). Have the controller find/get only whatever model data the view needs to do its job. Make controllers as thin as possible.

Prototypal inheritance

You can do a lot with jQuery without knowing about how JavaScript prototypal inheritance works. When developing AngularJS applications, you will avoid some common pitfalls if you have a good understanding of JavaScript inheritance. Recommended reading: What are the nuances of scope prototypal / prototypical inheritance in AngularJS?

depending on the cryptography algorithm you are using, you may have to add some padding bytes at the end before encrypting a byte array so that the length of the byte array is multiple of the block size:

Specifically in your case the padding schema you chose is PKCS5 which is described here: http://www.rsa.com/products/bsafe/documentation/cryptoj35html/doc/dev_guide/group_CJ_SYM__PAD.html

(I assume you have the issue when you try to encrypt)

You can choose your padding schema when you instantiate the Cipher object. Supported values depend on the security provider you are using.

By the way are you sure you want to use a symmetric encryption mechanism to encrypt passwords? Wouldn't be a one way hash better? If you really need to be able to decrypt passwords, DES is quite a weak solution, you may be interested in using something stronger like AES if you need to stay with a symmetric algorithm.

I seemed to have been able to solve it with:

if( $('your-selector-here').attr('id') === undefined){
    console.log( 'has no ID' )
}

Use transparent borders if possible.

  background-clip: padding-box;
  background-color: gold;
  border-right: 10px solid transparent;
}

.cell:last-child {
  border-right: 0 none;
}

Explanation

You could use the border-spacing property, as the accepted answer suggests, but this not only generates space between the table cells but also between the table cells and the table container. This may be unwanted.

If you don't need visible borders on your table cells you should therefore use transparent borders to generate cell margins. Transparent borders require setting background-clip: padding-box; because otherwise the background color of the table cells is displayed on the border.

Transparent borders and background-clip are supported in IE9 upwards (and all other modern browsers). If you need IE8 compatibility or don't need actual transparent space you can simply set a white border color and leave the background-clip out.

You can try this:

{!! $text !!}

You should have a look at: http://laravel.com/docs/5.0/upgrade#upgrade-5.0

devnull's answer provides a function:

mkfile() { mkdir -p -- "$1" && touch -- "$1"/"$2" }

This function did not work for me as is (I'm running bash 4.3.48 on WSL Ubuntu), but did work once I removed the double dashes. So, this worked for me:

echo 'mkfile() { mkdir -p "$1" && touch "$1"/"$2" }' >> ~/.bash_profile
source ~/.bash_profile
mkfile sample/dir test.file

The XmlTextWriter is usually used for generating (not updating) XML content. When you load the xml file into an XmlDocument, you don't need a separate writer.

Just update the node you have selected and .Save() that XmlDocument.

I think the main benefit would be when you define your own Display Templates, or use Data annotations.

So for example if your title was a date, you could define

[DisplayFormat(DataFormatString = "{0:d}")]

and then on every page it would display the value in a consistent manner. Otherwise you may have to customise the display on multiple pages. So it does not help much for plain strings, but it does help for currencies, dates, emails, urls, etc.

For example instead of an email address being a plain string it could show up as a link:

<a href="mailto:@ViewData.Model">@ViewData.TemplateInfo.FormattedModelValue</a>

We're using Install4J to build installers for windows or unix environments.

It's easily customizable up to the point where you want to write scripts for special actions that cannot be done with standard dialogues. But even though we're setting up windows services with it, we're only using standard components.

• installer + launcher
• windows or unix
• scriptable in Java
• ant task
• lots of customizable standard panels and actions
• optionally includes or downloads a JRE
• can also launch windows services
• multiple languages

I think Launch4J is from the same company (just the launcher - no installer).

PS: sadly i'm not getting paid for this endorsement. I just like that tool.

Assertions are checks which may get switched off. They're rarely used. Why?

• They must not be used for checking public method arguments as you have no control over them.
• They should not be used for simple checks like result != null as such checks are very fast and there's hardly anything to save.

So, what's left? Expensive checks for conditions really expected to be true. A good example would be the invariants of a data structure like RB-tree. Actually, in ConcurrentHashMap of JDK8, there are a few such meaningful asserts for the TreeNodes.

• You really don't want to switch them on in production as they could easily dominate the run time.
• You may want to switch them on or off during tests.
• You definitely want to switch them on when working on the code.

Sometimes, the check is not really expensive, but at the same time, you're pretty sure, it'll pass. In my code, there's e.g.,

assert Sets.newHashSet(userIds).size() == userIds.size();

where I'm pretty sure that the list I just created has unique elements, but I wanted to document and double check it.

Fitting a moving average to your data would smooth out the noise, see this this answer for how to do that.

If you'd like to use LOWESS to fit your data (it's similar to a moving average but more sophisticated), you can do that using the statsmodels library:

import numpy as np
import pylab as plt
import statsmodels.api as sm

x = np.linspace(0,2*np.pi,100)
y = np.sin(x) + np.random.random(100) * 0.2
lowess = sm.nonparametric.lowess(y, x, frac=0.1)

plt.plot(x, y, '+')
plt.plot(lowess[:, 0], lowess[:, 1])
plt.show()

Finally, if you know the functional form of your signal, you could fit a curve to your data, which would probably be the best thing to do.

Using CanvasJS, this works for me clearing chart and everything else, might work for you as well, granting you set your canvas/chart up fully before each processing elsewhere:

var myDiv= document.getElementById("my_chart_container{0}";
myDiv.innerHTML = "";

For all the Kotlin users out there:

context?.let {
    val color = ContextCompat.getColor(it, R.color.colorPrimary)
    // ...
}

I figured it out! The steps make it look like it will take more effort than it actually does.

These instructions are for creating a project from scratch. If you have existing Python scripts that you wish to include in this project, you will obviously need to slightly deviate from these instructions.

If you find that these instructions no longer work or are unclear due to changes in Xcode updates, please let me know. I will make the necessary corrections.

1. Open Xcode. The instructions for either are the same.
2. In the menu bar, click “File” ? “New” ? “New Project…”.
3. Select “Other” in the left pane, then "External Build System" in the right page, and next click "Next".
4. Enter the product name, organization name, or organization identifier.
5. For the “Build Tool” field, type in /usr/local/bin/python3 for Python 3 or /usr/bin/python for Python 2 and then click “Next”. Note that this assumes you have the symbolic link (that is setup by default) that resolves to the Python executable. If you are unsure as to where your Python executables are, enter either of these commands into Terminal: which python3 and which python.
6. Click “Next”.
7. Choose where to save it and click “Create”.
8. In the menu bar, click “File” ? “New” ? “New File…”.
9. Select “Other” under “OS X”.
10. Select “Empty” and click “Next”.
11. Navigate to the project folder (it will not work, otherwise), enter the name of the Python file (including the “.py” extension), and click “Create”.
12. In the menu bar, click “Product” ? “Scheme” ? “Edit Scheme…”.
13. Click “Run” in the left pane.
14. In the “Info” tab, click the “Executable” field and then click “Other…”.
15. Navigate to the executable from Step 5. You might need to use ??G to type in the directory if it is hidden.
16. Select the executable and click "Choose".
17. Uncheck “Debug executable”. If you skip this step, Xcode will try to debug the Python executable itself. I am unaware of a way to integrate an external debugging tool into Xcode.
18. Click the “+” icon under “Arguments Passed On Launch”. You might have to expand that section by clicking on the triangle pointing to the right.
19. Type in $(SRCROOT)/ (or $(SOURCE_ROOT)/) and then the name of the Python file you want to test. Remember, the Python program must be in the project folder. Otherwise, you will have to type out the full path (or relative path if it's in a subfolder of the project folder) here. If there are spaces anywhere in the full path, you must include quotation marks at the beginning and end of this.
20. Click “Close”.

Note that if you open the "Utilities" panel, with the "Show the File inspector" tab active, the file type is automatically set to "Default - Python script". Feel free to look through all the file type options it has, to gain an idea as to what all it is capable of doing. The method above can be applied to any interpreted language. As of right now, I have yet to figure out exactly how to get it to work with Java; then again, I haven't done too much research. Surely there is some documentation floating around on the web about all of this.

Running without administrative privileges:

If you do not have administrative privileges or are not in the Developer group, you can still use Xcode for Python programming (but you still won't be able to develop in languages that require compiling). Instead of using the play button, in the menu bar, click "Product" ? "Perform Action" ? "Run Without Building" or simply use the keyboard shortcut ^?R.

Other Notes:

To change the text encoding, line endings, and/or indentation settings, open the "Utilities" panel and click "Show the File inspector" tab active. There, you will find these settings.

For more information about Xcode's build settings, there is no better source than this. I'd be interested in hearing from somebody who got this to work with unsupported compiled languages. This process should work for any other interpreted language. Just be sure to change Step 5 and Step 16 accordingly.

make the image the exact size needed in the email. Windows MSO has a hard time resizing images in different scenarios.

in the case of using a 1px by 1px transparent png or gif as a spacer, defining the dimensions via width, height, or style attributes will work as expected in the majority of clients, but not windows MSO (of course).

example use case - you are using a background image and need to position a with a link inside over some part of the background image. Using a 1px by 1px spacer gif/png will only expand so wide (about 30px). You need size the spacer to the exact dimensions.

For completeness -- also check phpCallGraph.

Just increment i by 3 in each step:

  Debug.Assert((theData.Length % 3) == 0);  // 'theData' will always be divisible by 3

  for (int i = 0; i < theData.Length; i += 3)
  {
       //grab 3 items at a time and do db insert, 
       // continue until all items are gone..
       string item1 = theData[i+0];
       string item2 = theData[i+1];
       string item3 = theData[i+2];
       // use the items
  }

To answer some comments, it is a given that theData.Length is a multiple of 3 so there is no need to check for theData.Length-2 as an upperbound. That would only mask errors in the preconditions.

Using location.go(url) is the way to go, but instead of hardcoding the url , consider generating it using router.createUrlTree().

Given that you want to do the following router call: this.router.navigate([{param: 1}], {relativeTo: this.activatedRoute}) but without reloading the component, it can be rewritten as:

const url = this.router.createUrlTree([], {relativeTo: this.activatedRoute, queryParams: {param: 1}}).toString()

 this.location.go(url);

One of the uses which I found to be very useful is the print_function from __future__ module.

In Python 2.7, I wanted chars from different print statements to be printed on same line without spaces.

It can be done using a comma(",") at the end, but it also appends an extra space. The above statement when used as :

from __future__ import print_function
...
print (v_num,end="")
...

This will print the value of v_num from each iteration in a single line without spaces.

leftclickben answer worked for me, but I wanted a path from a given node back up the tree to the root, and these seemed to be going the other way, down the tree. So, I had to flip some of the fields around and renamed for clarity, and this works for me, in case this is what anyone else wants too--

item | parent
-------------
1    | null
2    | 1
3    | 1
4    | 2
5    | 4
6    | 3

and

select t.item_id as item, @pv:=t.parent as parent
from (select * from item_tree order by item_id desc) t
join
(select @pv:=6)tmp
where t.item_id=@pv;

gives:

item | parent
-------------
6    | 3
3    | 1
1    | null

FWIW, @SergeyL's answer is great, but here is a slight variant for testing. Note the change in logical or to logical and.

main.c has a main wrapper like this:

#if !defined(TEST_SPI) && !defined(TEST_SERIAL) && !defined(TEST_USB)
int main(int argc, char *argv[]) {
  // the true main() routine.
}

spi.c, serial.c and usb.c have main wrappers for their respective test code like this:

#ifdef TEST_USB
int main(int argc, char *argv[]) {
  // the  main() routine for testing the usb code.
}

config.h Which is included by all the c files has an entry like this:

// Uncomment below to test the serial
//#define TEST_SERIAL


// Uncomment below to test the spi code
//#define TEST_SPI

// Uncomment below to test the usb code
#define TEST_USB

A simple example of escaping quotes in the shell:

$ echo 'abc'\''abc'
abc'abc
$ echo "abc"\""abc"
abc"abc

It's done by finishing an already-opened one ('), placing the escaped one (\'), and then opening another one (').

Alternatively:

$ echo 'abc'"'"'abc'
abc'abc
$ echo "abc"'"'"abc"
abc"abc

It's done by finishing already opened one ('), placing a quote in another quote ("'"), and then opening another one (').

A static nested class interacts with the instance members of its outer class (and other classes) just like any other top-level class. In effect, a static nested class is behaviorally a top-level class that has been nested in another top-level class for packaging convenience.

The document says that you can use values to group the queryset .

class Travel(models.Model):
    interest = models.ForeignKey(Interest)
    user = models.ForeignKey(User)
    time = models.DateTimeField(auto_now_add=True)

# Find the travel and group by the interest:

>>> Travel.objects.values('interest').annotate(Count('user'))
<QuerySet [{'interest': 5, 'user__count': 2}, {'interest': 6, 'user__count': 1}]>
# the interest(id=5) had been visited for 2 times, 
# and the interest(id=6) had only been visited for 1 time.

>>> Travel.objects.values('interest').annotate(Count('user', distinct=True)) 
<QuerySet [{'interest': 5, 'user__count': 1}, {'interest': 6, 'user__count': 1}]>
# the interest(id=5) had been visited by only one person (but this person had 
#  visited the interest for 2 times

You can find all the books and group them by name using this code:

Book.objects.values('name').annotate(Count('id')).order_by() # ensure you add the order_by()

MySQL will assume the part before the equals references the columns named in the INSERT INTO clause, and the second part references the SELECT columns.

The easiest way is:

RandomAccessFile in = new RandomAccessFile("filename", "r"); 
int i = in.readInt();

-- or --

DataInputStream in = new DataInputStream(new BufferedInputStream(
    new FileInputStream("filename"))); 
int i = in.readInt();

Bitmap is Parcelable so you can add using [putExtra(String,Parcelable)][2] method, But not sure it is a best practice, If it is large size data it is better to store in a single place and use from both activities.

[2]: http://developer.android.com/reference/android/content/Intent.html#putExtra(java.lang.String, android.os.Parcelable)

This is the most simple solution for me:

just the current date

$tStamp = Get-Date -format yyyy_MM_dd_HHmmss

current date with some months added

$tStamp = Get-Date (get-date).AddMonths(6).Date -Format yyyyMMdd

There are a couple different ways I would do this:

1) Mimic Excel Tables Using with a Named Range

In your example, you named the range A10:A20 "Age". Depending on how you wanted to reference a cell in that range you could either (as @Alex P wrote) use =INDEX(Age, 5) or if you want to reference a cell in range "Age" that is on the same row as your formula, just use:

=INDEX(Age, ROW()-ROW(Age)+1)

This mimics the relative reference features built into Excel tables but is an alternative if you don't want to use a table.

If the named range is an entire column, the formula simplifies as:

=INDEX(Age, ROW())

2) Use an Excel Table

Alternatively if you set this up as an Excel table and type "Age" as the header title of the Age column, then your formula in columns to the right of the Age column can use a formula like this:

=[@[Age]]

_{Note: This is not a duplicate, because the OP is aware that the image from cv2.imread is in BGR format (unlike the suggested duplicate question that assumed it was RGB hence the provided answers only address that issue)}

To illustrate, I've opened up this same color JPEG image:

once using the conversion

img = cv2.imread(path)
img_gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

and another by loading it in gray scale mode

img_gray_mode = cv2.imread(path, cv2.IMREAD_GRAYSCALE)

Like you've documented, the diff between the two images is not perfectly 0, I can see diff pixels in towards the left and the bottom

I've summed up the diff too to see

import numpy as np
np.sum(diff)
# I got 6143, on a 494 x 750 image

I tried all cv2.imread() modes

Among all the IMREAD_ modes for cv2.imread(), only IMREAD_COLOR and IMREAD_ANYCOLOR can be converted using COLOR_BGR2GRAY, and both of them gave me the same diff against the image opened in IMREAD_GRAYSCALE

The difference doesn't seem that big. My guess is comes from the differences in the numeric calculations in the two methods (loading grayscale vs conversion to grayscale)

Naturally what you want to avoid is fine tuning your code on a particular version of the image just to find out it was suboptimal for images coming from a different source.

In brief, let's not mix the versions and types in the processing pipeline.

So I'd keep the image sources homogenous, e.g. if you have capturing the image from a video camera in BGR, then I'd use BGR as the source, and do the BGR to grayscale conversion cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

Vice versa if my ultimate source is grayscale then I'd open the files and the video capture in gray scale cv2.imread(path, cv2.IMREAD_GRAYSCALE)

using Eloquent

$data = array(
    array('user_id'=>'Coder 1', 'subject_id'=> 4096),
    array('user_id'=>'Coder 2', 'subject_id'=> 2048),
    //...
);

Model::insert($data);

Another thing you can do is cat out what you are echoing and pipe with inline cut -c 1-1

Not sure if you want jQuery.

var form;

form.onsubmit = function (e) {
  // stop the regular form submission
  e.preventDefault();

  // collect the form data while iterating over the inputs
  var data = {};
  for (var i = 0, ii = form.length; i < ii; ++i) {
    var input = form[i];
    if (input.name) {
      data[input.name] = input.value;
    }
  }

  // construct an HTTP request
  var xhr = new XMLHttpRequest();
  xhr.open(form.method, form.action, true);
  xhr.setRequestHeader('Content-Type', 'application/json; charset=UTF-8');

  // send the collected data as JSON
  xhr.send(JSON.stringify(data));

  xhr.onloadend = function () {
    // done
  };
};

One more solution:

• no toolbar but a segmented control (eyecandy)

  UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil 
                                                      delegate:nil
                                                      cancelButtonTitle:nil
                                                      destructiveButtonTitle:nil
                                                      otherButtonTitles:nil];
  
  [actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];
  
  CGRect pickerFrame = CGRectMake(0, 40, 0, 0);
  
  UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:pickerFrame];
  pickerView.showsSelectionIndicator = YES;
  pickerView.dataSource = self;
  pickerView.delegate = self;
  
  [actionSheet addSubview:pickerView];
  [pickerView release];
  
  UISegmentedControl *closeButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:@"Close"]];
  closeButton.momentary = YES; 
  closeButton.frame = CGRectMake(260, 7.0f, 50.0f, 30.0f);
  closeButton.segmentedControlStyle = UISegmentedControlStyleBar;
  closeButton.tintColor = [UIColor blackColor];
  [closeButton addTarget:self action:@selector(dismissActionSheet:) forControlEvents:UIControlEventValueChanged];
  [actionSheet addSubview:closeButton];
  [closeButton release];
  
  [actionSheet showInView:[[UIApplication sharedApplication] keyWindow]];
  
  [actionSheet setBounds:CGRectMake(0, 0, 320, 485)];

Another approach is to use a reverse proxy, which allows you to view Tensorboard from any internet connected device without SSHing. This approach can make it far easier / tractable to view Tensorboard on mobile devices, for example.

Steps:

1) Download reverse proxy Ngrok on your remote machine hosting Tensorboard. See https://ngrok.com/download for instructions (~5 minute setup).

2) Run ngrok http 6006 (assuming you're hosting Tensorboard on port 6006)

3) Save the URL that ngrok outputs:

4) Enter that into any browser to view TensorBoard:

Just add these code block on status return, and start passing a query string object {}. For JavaScript devs

After initializing your sdk.

step 1: // get login status

$(document).ready(function($) {
    FB.getLoginStatus(function(response) {
        statusChangeCallback(response);
        console.log(response);
    });
  });

This will check on document load and get your login status check if users has been logged in.

Then the function checkLoginState is called, and response is pass to statusChangeCallback

function checkLoginState() {
    FB.getLoginStatus(function(response) {
      statusChangeCallback(response);
    });
  }

Step 2: Let you get the response data from the status

function statusChangeCallback(response) {
    // body...
    if(response.status === 'connected'){
      // setElements(true);
      let userId = response.authResponse.userID;
      // console.log(userId);
      console.log('login');
      getUserInfo(userId);

    }else{
      // setElements(false);
      console.log('not logged in !');
    }
  }

This also has the userid which is being set to variable, then a getUserInfo func is called to fetch user information using the Graph-api.

function getUserInfo(userId) {
    // body...
    FB.api(
      '/'+userId+'/?fields=id,name,email',
      'GET',
      {},
      function(response) {
        // Insert your code here
        // console.log(response);
        let email = response.email;
        loginViaEmail(email);
      }
    );
  }

After passing the userid as an argument, the function then fetch all information relating to that userid. Note: in my case i was looking for the email, as to allowed me run a function that can logged user via email only.

// login via email

function loginViaEmail(email) {
    // body...
    let token = '{{ csrf_token() }}';

    let data = {
      _token:token,
      email:email
    }

    $.ajax({
      url: '/login/via/email',    
      type: 'POST',
      dataType: 'json',
      data: data,
      success: function(data){
        console.log(data);
        if(data.status == 'success'){
          window.location.href = '/dashboard';
        }

        if(data.status == 'info'){
          window.location.href = '/create-account'; 
        }
      },
      error: function(data){
        console.log('Error logging in via email !');
        // alert('Fail to send login request !');
      }
    });
  }

I ran into this problem while building a program that requires a huge amount of stack space (over 2 GiB). The solution was to add the flag -mcmodel=medium, which is supported by both GCC and Intel compilers.

Also, you can use spring annotation RequestMapping above controller class for receveing application/json;utf-8 in all responses

@Controller
@RequestMapping(produces = {"application/json; charset=UTF-8","*/*;charset=UTF-8"})
public class MyController{
 ...
}

Hm, you may 'have to' quit the application if, say, your application requires an internet connection. You could display an alert and then do something like this:

if ([[UIApplication sharedApplication] respondsToSelector:@selector(terminate)]) {
    [[UIApplication sharedApplication] performSelector:@selector(terminate)];
} else {
    kill(getpid(), SIGINT); 
}

In addition to what is said above, you should be very aware that nolock actually imposes the risk of you not getting rows that has been committed before your select.

See http://blogs.msdn.com/sqlcat/archive/2007/02/01/previously-committed-rows-might-be-missed-if-nolock-hint-is-used.aspx

As I know, PDO_MYSQLND replaced PDO_MYSQL in PHP 5.3. Confusing part is that name is still PDO_MYSQL. So now ND is default driver for MySQL+PDO.

Overall, to execute multiple queries at once you need:

• PHP 5.3+
• mysqlnd
• Emulated prepared statements. Make sure PDO::ATTR_EMULATE_PREPARES is set to 1 (default). Alternatively you can avoid using prepared statements and use $pdo->exec directly.

Using exec

$db = new PDO("mysql:host=localhost;dbname=test", 'root', '');

// works regardless of statements emulation
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, 0);

$sql = "
DELETE FROM car; 
INSERT INTO car(name, type) VALUES ('car1', 'coupe'); 
INSERT INTO car(name, type) VALUES ('car2', 'coupe');
";

$db->exec($sql);

Using statements

$db = new PDO("mysql:host=localhost;dbname=test", 'root', '');

// works not with the following set to 0. You can comment this line as 1 is default
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, 1);

$sql = "
DELETE FROM car; 
INSERT INTO car(name, type) VALUES ('car1', 'coupe'); 
INSERT INTO car(name, type) VALUES ('car2', 'coupe');
";

$stmt = $db->prepare($sql);
$stmt->execute();

A note:

When using emulated prepared statements, make sure you have set proper encoding (that reflects actual data encoding) in DSN (available since 5.3.6). Otherwise there can be a slight possibility for SQL injection if some odd encoding is used.

I am not familiar with sox, but instead of making repeated calls to the program as a command line, is it possible to set it up as a service and connect to it for requests? You can take a look at the connection interface such as sqlite for inspiration.

Received SQLSTATE 01000 in the following error message below:

SQL Agent - Jobs Failed: The SQL Agent Job "LiteSpeed Backup Full" has failed with the message "The job failed. The Job was invoked by User X. The last step to run was step 1 (Step1). NOTE: Failed to notify via email. - Executed as user: X. LiteSpeed(R) for SQL Server Version 6.5.0.1460 Copyright 2011 Quest Software, Inc. [SQLSTATE 01000] (Message 1) LiteSpeed for SQL Server could not open backup file: (N:\BACKUP2\filename.BAK). The previous system message is the reason for the failure. [SQLSTATE 42000] (Error 60405). The step failed."

In my case this was related to permission on drive N following an SQL Server failover on an Active/Passive SQL cluster.

All SQL resources where failed over to the seconary resouce and back to the preferred node following maintenance. When the Quest LiteSpeed job then executed on the preferred node it was clear the previous permissions for SQL server user X had been lost on drive N and SQLSTATE 10100 was reported.

Simply added the permissions again to the backup destination drive and the issue was resolved.

Hope that helps someone.

If you need by several params:

$ids = [1,2,3,4];
$not_ids = [5,6,7,8];
DB::table('table')->whereIn('id', $ids)
                  ->whereNotIn('id', $not_ids)
                  ->where('status', 1)
                  ->get();

Yes, this is an old question. But it's misleading, as this was the first result in my search, and both the answers aren't correct anymore.

You can change your Github account name at any time.

To do this, click your profile picture > Settings > Account Settings > Change Username.

Links to your repositories will redirect to the new URLs, but they should be updated on other sites because someone who chooses your abandoned username can override the links. Links to your profile page will be 404'd.

For more information, see the official help page.

And furthermore, if you want to change your username to something else, but that specific username is being taken up by someone else who has been completely inactive for the entire time their account has existed, you can report their account for name squatting.

As it says, it is ambiguous. Your array comparison returns a boolean array. Methods any() and all() reduce values over the array (either logical_or or logical_and). Moreover, you probably don't want to check for equality. You should replace your condition with:

np.allclose(A.dot(eig_vec[:,col]), eig_val[col] * eig_vec[:,col])

You can also set the title of your chart by adding the title parameter as follows

ax.set(xlabel='common xlabel', ylabel='common ylabel', title='some title')

I used the RowHeight property of a range (which means cells as well). If it's zero then it's hidden. So just loop through all rows as you would normally but in the if condition check for that property as in If myRange.RowHeight > 0 then DoStuff where DoStuff is something you want to do with the visible cells.

I had a similar problem with a physical device. The problem was related with the fact that the google app ( the search bar for google on top ) was disabled. After the first reboot launcher3 began failing. No matter how many cache/data cleaning I did, it kept failing. I reenabled it and launched it, so it appeared again on the screen and from that moment on, launcher3 was back to life.

I guess there mmust be some kind of dependency with this app.
