There is no tuple type in Go, and you are correct, the multiple values returned by functions do not represent a first-class object.

Nick's answer shows how you can do something similar that handles arbitrary types using interface{}. (I might have used an array rather than a struct to make it indexable like a tuple, but the key idea is the interface{} type)

My other answer shows how you can do something similar that avoids creating a type using anonymous structs.

These techniques have some properties of tuples, but no, they are not tuples.

I got a bit annoyed with reading that multiline syntax is indeed been planned for jdk7 (after about how many decades of java existence?). Funnily, there is not even yet a readAll() function for reading the complete contents of a file (from jdk7 only, huhh), so the code below reads single lines.

/*
  MakeMultiline v1.0 (2010) - Free to use and copy.

  Small gadget to turn text blobs into one java string literal
  (doing the split in lines, adding \n at each end and enclosing
  in double quotes). Does escape quotes encountered in the text blob.

  Useful for working around missing multiline string syntax in java
  prior jdk7. Use with:

     java MakeMultiline "    "
  or
     java MakeMultiline "    " mytextfile.txt
*/

import java.io.*;

class MakeMultiline {
  public static void main(String[] args) {
    try {
      // args[0]: indent
      // args[1]: filename to read (optional; stdin if not given)
      // Beware the nmb of newlines at the end when using stdin!

      String indent = (args.length > 0 ? args[0] : "");
      FileReader fr = null; BufferedReader br;
      if (args.length > 1)
        { fr =  new FileReader(args[1]); br = new BufferedReader(fr); }
      else
        { br = new BufferedReader(new InputStreamReader(System.in)); }
      String s; String res = "";
      while((s = br.readLine()) != null) {
        if (res.length() > 0) res += " +\n";
        res += indent + "\"" + s.replace("\"", "\\\"") + "\\n\"";
      }
      br.close(); if (fr != null) fr.close();
      System.out.println(res + ";");
    }
    catch(Exception e) {
      System.out.println("Exception: " + e);
    }
  }
}

This was the quickest solution for me. (2010-01-27)

OOP and the GoF patterns deal with states. OOP models reality to keep the code base as near as possible to the given requirements of reality. GoF design patterns are patterns that were identified to solve atomic real world problems. They handle the problem of state in a semantic way.

As in real functional programming no state exists, it does not make sense to apply the GoF patterns. There are not functional design patterns in the same way there are GoF design patterns. Every functional design pattern is artifical in contrast to reality as functions are constructs of math and not reality.

Functions lack the concept of time as they are always return the same value whatever the current time is unless time is part of the function parameters what makes it really hard to prrocess "future requests". Hybrid languages mix those concepts make the languages not real functional programming languages.

Functional languages are rising only because of one thing: the current natural restrictions of physics. Todays processors are limited in their speed of processing instructions due to physical laws. You see a stagnation in clock frequency but an expansion in processing cores. That's why parallelism of instructions becomes more and more important to increase speed of modern applications. As functional programming by definition has no state and therefore has no side effects it is safe to process functions safely in parallel.

GoF patterns are not obsolete. They are at least necessary to model the real world requirements. But if you use a functional programming language you have to transform them into their hybrid equivalents. Finally you have no chance to make only functional programs if you use persistence. For the hybrid elements of your program there remains the necessity to use GoF patterns. For any other element that is purely functional there is no necessity to use GoF patterns because there is no state.

Because the GoF patterns are not necessary for real functional programming, it doesn't mean that the SOLID principles should not be applied. The SOLID principles are beyond any language paradigm.

The main differences between InnoDB and MyISAM ("with respect to designing a table or database" you asked about) are support for "referential integrity" and "transactions".

If you need the database to enforce foreign key constraints, or you need the database to support transactions (i.e. changes made by two or more DML operations handled as single unit of work, with all of the changes either applied, or all the changes reverted) then you would choose the InnoDB engine, since these features are absent from the MyISAM engine.

Those are the two biggest differences. Another big difference is concurrency. With MyISAM, a DML statement will obtain an exclusive lock on the table, and while that lock is held, no other session can perform a SELECT or a DML operation on the table.

Those two specific engines you asked about (InnoDB and MyISAM) have different design goals. MySQL also has other storage engines, with their own design goals.

So, in choosing between InnoDB and MyISAM, the first step is in determining if you need the features provided by InnoDB. If not, then MyISAM is up for consideration.

A more detailed discussion of differences is rather impractical (in this forum) absent a more detailed discussion of the problem space... how the application will use the database, how many tables, size of the tables, the transaction load, volumes of select, insert, updates, concurrency requirements, replication features, etc.

The logical design of the database should be centered around data analysis and user requirements; the choice to use a relational database would come later, and even later would the choice of MySQL as a relational database management system, and then the selection of a storage engine for each table.

This is a safety measure to avoid pushing branches that are not ready to be published. Loosely speaking, by executing "git push", only local branches that already exist on the server with the same name will be pushed, or branches that have been pushed using the localbranch:remotebranch syntax.

To push all local branches to the remote repository, use --all:

git push REMOTENAME --all
git push --all

or specify all branches you want to push:

git push REMOTENAME master exp-branch-a anotherbranch bugfix

In addition, it's useful to add -u to the "git push" command, as this will tell you if your local branch is ahead or behind the remote branch. This is shown when you run "git status" after a git fetch.

Maybe the solution someone is looking for is this:

Response.Redirect("/Sucesso")

This work when used in the View as well.

In vue cli-3 You can define the variable in main.js like

window.basurl="http://localhost:8000/";

And you can also access this variable in any component by using the the window.basurl

SELECT * FROM (
    SELECT * FROM table_name ORDER BY sortable_column DESC
) WHERE ROWNUM = 1;

In case you need to define two or more excludeFilters criteria, you have to use the array.

For instances in this section of code I want to exclude all the classes in the org.xxx.yyy package and another specific class, MyClassToExclude

 @ComponentScan(            
        excludeFilters = {
                @ComponentScan.Filter(type = FilterType.REGEX, pattern = "org.xxx.yyy.*"),
                @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = MyClassToExclude.class) })

Also, the apt-show-versions package (installed separately) parses dpkg information about what is installed and tells you if packages are up to date.

Example..

$ sudo apt-show-versions --regex chrome
google-chrome-stable/stable upgradeable from 32.0.1700.102-1 to 35.0.1916.114-1
xserver-xorg-video-openchrome/quantal-security uptodate 1:0.3.1-0ubuntu1.12.10.1
$

Also you could use like below in C++.

int j=3;
int i=2;
for (; i<n && j<n ; j=j+2, i=i+2){
  // your code
}

numpy provides a simple function to do the exact same thing: supposing you have a masked array 'a', calling numpy.ma.compress_rows(a) will delete the rows containing a masked value. I guess this is much faster this way...

An improvement based on the post by Dishan TD (which removes the vertical margin as well):

  .slick-slide{
    margin-left:  15px;
    margin-right:  15px;
  }

  .slick-list {
    margin-left: -15px;
    margin-right: -15px;
    pointer-events: none;
  }

Note: the pointer-events was necessary in my case, to be able to click on the left arrow.

if (Build.VERSION.SDK_INT >= 11) {
        Point size = new Point();
        try {
            this.getWindowManager().getDefaultDisplay().getRealSize(size);
            screenWidth = size.x;
            screenHeight = size.y;
        } catch (NoSuchMethodError e) {
             screenHeight = this.getWindowManager().getDefaultDisplay().getHeight();
             screenWidth=this.getWindowManager().getDefaultDisplay().getWidth();
        }

    } else {
        DisplayMetrics metrics = new DisplayMetrics();
        this.getWindowManager().getDefaultDisplay().getMetrics(metrics);
        screenWidth = metrics.widthPixels;
        screenHeight = metrics.heightPixels;
    }

A quick one liner to get the first entry returned. This is nice for very basic queries.

<?php
$count = current($db->query("select count(*) from table")->fetch());
?>

Reference

You can access your methods in the Ruby on Rails console like the following:

controller.method_name
helper.method_name

Dialog pop up fill default black background color or theme color so you need to set TRANSPARENT background into Dialog. Try below code:-

final Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
dialog.setContentView(R.layout.splash);
dialog.show();

I recently wrote a custom directive which can be generic enough to do any validation. It take a validation function from the current scope

module.directive('customValidator', [function () {
        return {
            restrict: 'A',
            require: 'ngModel',
            scope: { validateFunction: '&' },
            link: function (scope, elm, attr, ngModelCtrl) {
                ngModelCtrl.$parsers.push(function (value) {
                    var result = scope.validateFunction({ 'value': value });
                    if (result || result === false) {
                        if (result.then) {
                            result.then(function (data) {           //For promise type result object
                                ngModelCtrl.$setValidity(attr.customValidator, data);
                            }, function (error) {
                                ngModelCtrl.$setValidity(attr.customValidator, false);
                            });
                        }
                        else {
                            ngModelCtrl.$setValidity(attr.customValidator, result);
                            return result ? value : undefined;      //For boolean result return based on boolean value
                        }
                    }
                    return value;
                });
            }
        };
    }]);

To use it you do

<input type="email" name="email2" ng-model="emailReg2" custom-validator='emailMatch' data-validate-function='checkEmailMatch(value)'>
<span ng-show="registerForm.email2.$error.emailMatch">Emails have to match!</span>

In you controller then you can implement the method, that should return true or false

$scope.checkEmailMatch=function(value) {
    return value===$scope.emailReg;
}

The advantage is that you do not have to write custom directive for each custom validation.

204 No Content

The server has fulfilled the request but does not need to return an entity-body, and might want to return updated metainformation. The response MAY include new or updated metainformation in the form of entity-headers, which if present SHOULD be associated with the requested variant.

According to the RFC part for the status code 204, it seems to me a valid choice for a GET request.

A 404 Not Found, 200 OK with empty body and 204 No Content have completely different meaning, sometimes we can't use proper status code but bend the rules and they will come back to bite you one day or later. So, if you can use proper status code, use it!

I think the choice of GET or POST is very personal as both of them will do the work but I would recommend you to keep a POST instead of a GET, for two reasons:

• You want the other part (the servlet if I understand correctly) to perform an action not retrieve some data from it.
• By default GET requests are cacheable if there are no parameters present in the URL, a POST is not.

You don't have to use dynamic SQL

update
    R
set
    Assoc_Item_1 = CASE WHEN @curr_row = 1 THEN foo.relsku ELSE Assoc_Item_1 END,
    Assoc_Item_2 = CASE WHEN @curr_row = 2 THEN foo.relsku ELSE Assoc_Item_2 END,
    Assoc_Item_3 = CASE WHEN @curr_row = 3 THEN foo.relsku ELSE Assoc_Item_3 END,
    Assoc_Item_4 = CASE WHEN @curr_row = 4 THEN foo.relsku ELSE Assoc_Item_4 END,
    Assoc_Item_5 = CASE WHEN @curr_row = 5 THEN foo.relsku ELSE Assoc_Item_5 END,
    ...
from
    (Select relsku From @TSku Where tid = @curr_row1) foo
    CROSS JOIN
    @RelPro R
Where
     R.RowID = @curr_row;

It can happen that the cause is not that you don't find the right directory. For example, you can read from the file (even without absolute path) but it seems you cannot write into it.

In that case, it might be that you program exits before the writing can be finished.

If your program uses an event loop (like with a GUI application, e.g. QMainWindow) it's not a problem. However, if your program exits immediately after writing to the file, you should flush the text stream, closing the file is not always enough (and it's unnecessary, as it is closed in the destructor).

stream << "something" << endl;
stream.flush();

This guarantees that the changes are committed to the file before the program continues from this instruction.

The problem seems to be that the QFile is destructed before the QTextStream. So, even if the stream is flushed in the QTextStream destructor, it's too late, as the file is already closed.

The simple way is:

import numpy as np
np.exp(np.log(your_array).sum())

As of API 21, you could also use:

   ResourcesCompat.getDrawable(getResources(), R.drawable.name, null);

Instead of ContextCompat.getDrawable(context, android.R.drawable.ic_dialog_email)

Well I agree with above answers but still there can be an another way to do this and it is by using media queries.

Suppose this is what you want to do :

body.nontouch nav a:hover {
    background: yellow;
}

then you can do this by media query as :

@media(hover: hover) and (pointer: fine) {
    nav a:hover {
        background: yellow;
    }
}

And for more details you can visit this page.

df.index

• outputs the row names as pandas Index object.

list(df.index)

• casts to a list.

df.index['Row 2':'Row 5']

• supports label slicing similar to columns.

Sorry, but I'm pretty sure Peter's answer is wrong. Note that the y axis goes down the page (common in graphics). As such the deltaY calculation has to be reversed, or you get the wrong answer.

Consider:

System.out.println (Math.toDegrees(Math.atan2(1,1)));
System.out.println (Math.toDegrees(Math.atan2(-1,1)));
System.out.println (Math.toDegrees(Math.atan2(1,-1)));
System.out.println (Math.toDegrees(Math.atan2(-1,-1)));

gives

45.0
-45.0
135.0
-135.0

So if in the example above, P1 is (1,1) and P2 is (2,2) [because Y increases down the page], the code above will give 45.0 degrees for the example shown, which is wrong. Change the order of the deltaY calculation and it works properly.

The general Angular way to get access to an element that triggered an event is to write a directive and bind() to the desired event:

app.directive('myChange', function() {
  return function(scope, element) {
    element.bind('change', function() {
      alert('change on ' + element);
    });
  };
});

or with DDO (as per @tpartee's comment below):

app.directive('myChange', function() {
  return { 
    link:  function link(scope, element) {
      element.bind('change', function() {
        alert('change on ' + element);
      });
    }
  }
});

The above directive can be used as follows:

<input id="searchText" ng-model="searchText" type="text" my-change>

Plunker.

Type into the text field, then leave/blur. The change callback function will fire. Inside that callback function, you have access to element.

Some built-in directives support passing an $event object. E.g., ng-*click, ng-Mouse*. Note that ng-change does not support this event.

Although you can get the element via the $event object:

<button ng-click="clickit($event)">Hello</button>

$scope.clickit = function(e) {
    var elem = angular.element(e.srcElement);
    ...

this goes "deep against the Angular way" -- Misko.

That only means that an undefined column or parameter name was detected. The errror that DB2 gives should point what that may be:

DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=[THE_UNDEFINED_COLUMN_OR_PARAMETER_NAME], DRIVER=4.8.87

Double check your table definition. Maybe you just missed adding something.

I also tried google-ing this problem and saw this:

http://www.coderanch.com/t/515475/JDBC/databases/sql-insert-statement-giving-sqlcode

The correct answer should be 2nCn/(n+1) for unlabelled nodes and if the nodes are labelled then (2nCn)*n!/(n+1).

There are many ways to do this. To fix your current code using %-formatting, you need to pass in a tuple:

1. Pass it as a tuple:

   print("Total score for %s is %s" % (name, score))
   

A tuple with a single element looks like ('this',).

Here are some other common ways of doing it:

2. Pass it as a dictionary:

   print("Total score for %(n)s is %(s)s" % {'n': name, 's': score})
   

There's also new-style string formatting, which might be a little easier to read:

3. Use new-style string formatting:

   print("Total score for {} is {}".format(name, score))
   

4. Use new-style string formatting with numbers (useful for reordering or printing the same one multiple times):

   print("Total score for {0} is {1}".format(name, score))
   

5. Use new-style string formatting with explicit names:

   print("Total score for {n} is {s}".format(n=name, s=score))
   

6. Concatenate strings:

   print("Total score for " + str(name) + " is " + str(score))
   

The clearest two, in my opinion:

7. Just pass the values as parameters:

   print("Total score for", name, "is", score)
   

   If you don't want spaces to be inserted automatically by print in the above example, change the sep parameter:

   print("Total score for ", name, " is ", score, sep='')
   

   If you're using Python 2, won't be able to use the last two because print isn't a function in Python 2. You can, however, import this behavior from __future__:

   from __future__ import print_function
   

8. Use the new f-string formatting in Python 3.6:

   print(f'Total score for {name} is {score}')
   

If you are learning it's helpful to use a GUI like SQLyog, make the changes using the program and then see the History tab for the DDL statements that made those changes.

You can use groupby, assuming you have an integer enumerated index:

import math
df = pd.DataFrame(dict(sample=np.arange(99)))
rows_per_subframe = math.ceil(len(df) / 4.)

subframes = [i[1] for i in df.groupby(np.arange(len(df))//rows_per_subframe)]

Note: groupby returns a tuple in which the 2nd element is the dataframe, thus the slightly complicated extraction.

>>> len(subframes), [len(i) for i in subframes]
(4, [25, 25, 25, 24])

Here is another example of subtracting two dates in C# ...

if ( DateTime.Now.Subtract(Convert.ToDateTime(objDateValueFromDatabase.CreatedOn)).TotalHours > 24 ) 
{ 
... 
} 

EditText editText= ....;
InputFilter[] fa= new InputFilter[1];
fa[0] = new InputFilter.LengthFilter(8);
editText.setFilters(fa);

See ?which.max

> which.max( matrix[,2] )
[1] 2

I used this:

$('.nav-list li.active').removeClass('active');
$(this).parent().addClass('active');

Since the active class is in the <li> element and what is clicked is the <a> element, the first line removes .active from all <li> and the second one (again, $(this) represents <a> which is the clicked element) adds .active to the direct parent, which is <li>.

$(window).scroll(function() {    
    $('.logo_container, .slogan').css({
        "opacity" : ".1",
        "transition" : "opacity .8s ease-in-out"
    });
});

Just Right Click on "Python Environment" and Click to "Add Environment"

Set a property for the current lesson: currentLesson. It will hold, obviously, the 'number' of the choosen lesson. On each button click, set the currentLesson value to 'number'/ order of the button, i.e. for the first button, it will be '1', for the second '2' and so on. Each button now can be disabled with [disabled] attribute, if it the currentLesson is not the same as it's order.

HTML

  <button  (click)="currentLesson = '1'"
         [disabled]="currentLesson !== '1'" class="primair">
           Start lesson</button>
  <button (click)="currentLesson = '2'"
         [disabled]="currentLesson !== '2'" class="primair">
           Start lesson</button>
 .....//so on

Typescript

currentLesson:string;

  classes = [
{
  name: 'string',
  level: 'string',
  code: 'number',
  currentLesson: '1'
}]

constructor(){
  this.currentLesson=this.classes[0].currentLesson
}

DEMO

Putting everything in a loop:

HTML

<div *ngFor="let class of classes; let i = index">
   <button [disabled]="currentLesson !== i + 1" class="primair">
           Start lesson {{i +  1}}</button>
</div>

Typescript

currentLesson:string;

classes = [
{
  name: 'Lesson1',
  level: 1,
  code: 1,
},{
  name: 'Lesson2',
  level: 1,

If on OSX or *NIX use

Get all actual lines of java code from *.java files

find . -name "*.java" -exec grep "[a-zA-Z0-9{}]" {} \; | wc -l

Get all lines from the *.java files, which includes empty lines and comments

find . -name "*.java" -exec cat | wc -l

Get information per File, this will give you [ path to file + "," + number of lines ]

find . -name "*.java" -exec wc -l {} \;

To my knowledge, you cannot disable the browser window.

What you can do is create a jQuery (or a similar kind of ) popup and when this popup appears your parent browser will be disabled.

Open your child page in popup.

You can use the action 'Fix doc comment'. It doesn't have a default shortcut, but you can assign the Alt+Shift+J shortcut to it in the Keymap, because this shortcut isn't used for anything else. By default, you can also press Ctrl+Shift+A two times and begin typing Fix doc comment in order to find the action.

Similar topic is discussed here Equivalent of $compile in Angular 2. We need to use JitCompiler and NgModule. Read more about NgModule in Angular2 here:

• Angular 2 RC5 - NgModules, Lazy Loading and AoT compilation

In a Nutshell

There is a working plunker/example (dynamic template, dynamic component type, dynamic module,JitCompiler, ... in action)

The principal is:
1) create Template
2) find ComponentFactory in cache - go to 7)
3) - create Component
4) - create Module
5) - compile Module
6) - return (and cache for later use) ComponentFactory
7) use Target and ComponentFactory to create an Instance of dynamic Component

Here is a code snippet (more of it here) - Our custom Builder is returning just built/cached ComponentFactory and the view Target placeholder consume to create an instance of the DynamicComponent

  // here we get a TEMPLATE with dynamic content === TODO
  var template = this.templateBuilder.prepareTemplate(this.entity, useTextarea);

  // here we get Factory (just compiled or from cache)
  this.typeBuilder
      .createComponentFactory(template)
      .then((factory: ComponentFactory<IHaveDynamicData>) =>
    {
        // Target will instantiate and inject component (we'll keep reference to it)
        this.componentRef = this
            .dynamicComponentTarget
            .createComponent(factory);

        // let's inject @Inputs to component instance
        let component = this.componentRef.instance;

        component.entity = this.entity;
        //...
    });

This is it - in nutshell it. To get more details.. read below

TL&DR

Observe a plunker and come back to read details in case some snippet requires more explanation

Detailed explanation - Angular2 RC6++ & runtime components

Below description of this scenario, we will

1. create a module PartsModule:NgModule (holder of small pieces)
2. create another module DynamicModule:NgModule, which will contain our dynamic component (and reference PartsModule dynamically)
3. create dynamic Template (simple approach)
4. create new Component type (only if template has changed)
5. create new RuntimeModule:NgModule. This module will contain the previously created Component type
6. call JitCompiler.compileModuleAndAllComponentsAsync(runtimeModule) to get ComponentFactory
7. create an Instance of the DynamicComponent - job of the View Target placeholder and ComponentFactory
8. assign @Inputs to new instance (switch from INPUT to TEXTAREA editing), consume @Outputs

NgModule

We need an NgModules.

While I would like to show a very simple example, in this case, I would need three modules (in fact 4 - but I do not count the AppModule). Please, take this rather than a simple snippet as a basis for a really solid dynamic component generator.

There will be one module for all small components, e.g. string-editor, text-editor (date-editor, number-editor...)

@NgModule({
  imports:      [ 
      CommonModule,
      FormsModule
  ],
  declarations: [
      DYNAMIC_DIRECTIVES
  ],
  exports: [
      DYNAMIC_DIRECTIVES,
      CommonModule,
      FormsModule
  ]
})
export class PartsModule { }

Where DYNAMIC_DIRECTIVES are extensible and are intended to hold all small parts used for our dynamic Component template/type. Check app/parts/parts.module.ts

The second will be module for our Dynamic stuff handling. It will contain hosting components and some providers.. which will be singletons. Therefor we will publish them standard way - with forRoot()

import { DynamicDetail }          from './detail.view';
import { DynamicTypeBuilder }     from './type.builder';
import { DynamicTemplateBuilder } from './template.builder';

@NgModule({
  imports:      [ PartsModule ],
  declarations: [ DynamicDetail ],
  exports:      [ DynamicDetail],
})

export class DynamicModule {

    static forRoot()
    {
        return {
            ngModule: DynamicModule,
            providers: [ // singletons accross the whole app
              DynamicTemplateBuilder,
              DynamicTypeBuilder
            ], 
        };
    }
}

Check the usage of the forRoot() in the AppModule

Finally, we will need an adhoc, runtime module.. but that will be created later, as a part of DynamicTypeBuilder job.

The forth module, application module, is the one who keeps declares compiler providers:

...
import { COMPILER_PROVIDERS } from '@angular/compiler';    
import { AppComponent }   from './app.component';
import { DynamicModule }    from './dynamic/dynamic.module';

@NgModule({
  imports:      [ 
    BrowserModule,
    DynamicModule.forRoot() // singletons
  ],
  declarations: [ AppComponent],
  providers: [
    COMPILER_PROVIDERS // this is an app singleton declaration
  ],

Read (do read) much more about NgModule there:

• Angular 2 RC5 - NgModules, Lazy Loading and AoT compilation
• Angular Modules documentation

A template builder

In our example we will process detail of this kind of entity

entity = { 
    code: "ABC123",
    description: "A description of this Entity" 
};

To create a template, in this plunker we use this simple/naive builder.

The real solution, a real template builder, is the place where your application can do a lot

// plunker - app/dynamic/template.builder.ts
import {Injectable} from "@angular/core";

@Injectable()
export class DynamicTemplateBuilder {

    public prepareTemplate(entity: any, useTextarea: boolean){
      
      let properties = Object.keys(entity);
      let template = "<form >";
      let editorName = useTextarea 
        ? "text-editor"
        : "string-editor";
        
      properties.forEach((propertyName) =>{
        template += `
          <${editorName}
              [propertyName]="'${propertyName}'"
              [entity]="entity"
          ></${editorName}>`;
      });
  
      return template + "</form>";
    }
}

A trick here is - it builds a template which uses some set of known properties, e.g. entity. Such property(-ies) must be part of dynamic component, which we will create next.

To make it a bit more easier, we can use an interface to define properties, which our Template builder can use. This will be implemented by our dynamic Component type.

export interface IHaveDynamicData { 
    public entity: any;
    ...
}

A ComponentFactory builder

Very important thing here is to keep in mind:

our component type, build with our DynamicTypeBuilder, could differ - but only by its template (created above). Components' properties (inputs, outputs or some protected) are still same. If we need different properties, we should define different combination of Template and Type Builder

So, we are touching the core of our solution. The Builder, will 1) create ComponentType 2) create its NgModule 3) compile ComponentFactory 4) cache it for later reuse.

An dependency we need to receive:

// plunker - app/dynamic/type.builder.ts
import { JitCompiler } from '@angular/compiler';
    
@Injectable()
export class DynamicTypeBuilder {

  // wee need Dynamic component builder
  constructor(
    protected compiler: JitCompiler
  ) {}

And here is a snippet how to get a ComponentFactory:

// plunker - app/dynamic/type.builder.ts
// this object is singleton - so we can use this as a cache
private _cacheOfFactories:
     {[templateKey: string]: ComponentFactory<IHaveDynamicData>} = {};
  
public createComponentFactory(template: string)
    : Promise<ComponentFactory<IHaveDynamicData>> {    
    let factory = this._cacheOfFactories[template];

    if (factory) {
        console.log("Module and Type are returned from cache")
       
        return new Promise((resolve) => {
            resolve(factory);
        });
    }
    
    // unknown template ... let's create a Type for it
    let type   = this.createNewComponent(template);
    let module = this.createComponentModule(type);
    
    return new Promise((resolve) => {
        this.compiler
            .compileModuleAndAllComponentsAsync(module)
            .then((moduleWithFactories) =>
            {
                factory = _.find(moduleWithFactories.componentFactories
                                , { componentType: type });

                this._cacheOfFactories[template] = factory;

                resolve(factory);
            });
    });
}

Above we create and cache both Component and Module. Because if the template (in fact the real dynamic part of that all) is the same.. we can reuse

And here are two methods, which represent the really cool way how to create a decorated classes/types in runtime. Not only @Component but also the @NgModule

protected createNewComponent (tmpl:string) {
  @Component({
      selector: 'dynamic-component',
      template: tmpl,
  })
  class CustomDynamicComponent  implements IHaveDynamicData {
      @Input()  public entity: any;
  };
  // a component for this particular template
  return CustomDynamicComponent;
}
protected createComponentModule (componentType: any) {
  @NgModule({
    imports: [
      PartsModule, // there are 'text-editor', 'string-editor'...
    ],
    declarations: [
      componentType
    ],
  })
  class RuntimeComponentModule
  {
  }
  // a module for just this Type
  return RuntimeComponentModule;
}

Important:

our component dynamic types differ, but just by template. So we use that fact to cache them. This is really very important. Angular2 will also cache these.. by the type. And if we would recreate for the same template strings new types... we will start to generate memory leaks.

ComponentFactory used by hosting component

Final piece is a component, which hosts the target for our dynamic component, e.g. <div #dynamicContentPlaceHolder></div>. We get a reference to it and use ComponentFactory to create a component. That is in a nutshell, and here are all the pieces of that component (if needed, open plunker here)

Let's firstly summarize import statements:

import {Component, ComponentRef,ViewChild,ViewContainerRef}   from '@angular/core';
import {AfterViewInit,OnInit,OnDestroy,OnChanges,SimpleChange} from '@angular/core';

import { IHaveDynamicData, DynamicTypeBuilder } from './type.builder';
import { DynamicTemplateBuilder }               from './template.builder';

@Component({
  selector: 'dynamic-detail',
  template: `
<div>
  check/uncheck to use INPUT vs TEXTAREA:
  <input type="checkbox" #val (click)="refreshContent(val.checked)" /><hr />
  <div #dynamicContentPlaceHolder></div>  <hr />
  entity: <pre>{{entity | json}}</pre>
</div>
`,
})
export class DynamicDetail implements AfterViewInit, OnChanges, OnDestroy, OnInit
{ 
    // wee need Dynamic component builder
    constructor(
        protected typeBuilder: DynamicTypeBuilder,
        protected templateBuilder: DynamicTemplateBuilder
    ) {}
    ...

We just receive, template and component builders. Next are properties which are needed for our example (more in comments)

// reference for a <div> with #dynamicContentPlaceHolder
@ViewChild('dynamicContentPlaceHolder', {read: ViewContainerRef}) 
protected dynamicComponentTarget: ViewContainerRef;
// this will be reference to dynamic content - to be able to destroy it
protected componentRef: ComponentRef<IHaveDynamicData>;

// until ngAfterViewInit, we cannot start (firstly) to process dynamic stuff
protected wasViewInitialized = false;

// example entity ... to be recieved from other app parts
// this is kind of candiate for @Input
protected entity = { 
    code: "ABC123",
    description: "A description of this Entity" 
  };

In this simple scenario, our hosting component does not have any @Input. So it does not have to react to changes. But despite of that fact (and to be ready for coming changes) - we need to introduce some flag if the component was already (firstly) initiated. And only then we can start the magic.

Finally we will use our component builder, and its just compiled/cached ComponentFacotry. Our Target placeholder will be asked to instantiate the Component with that factory.

protected refreshContent(useTextarea: boolean = false){
  
  if (this.componentRef) {
      this.componentRef.destroy();
  }
  
  // here we get a TEMPLATE with dynamic content === TODO
  var template = this.templateBuilder.prepareTemplate(this.entity, useTextarea);

  // here we get Factory (just compiled or from cache)
  this.typeBuilder
      .createComponentFactory(template)
      .then((factory: ComponentFactory<IHaveDynamicData>) =>
    {
        // Target will instantiate and inject component (we'll keep reference to it)
        this.componentRef = this
            .dynamicComponentTarget
            .createComponent(factory);

        // let's inject @Inputs to component instance
        let component = this.componentRef.instance;

        component.entity = this.entity;
        //...
    });
}

small extension

Also, we need to keep a reference to compiled template.. to be able properly destroy() it, whenever we will change it.

// this is the best moment where to start to process dynamic stuff
public ngAfterViewInit(): void
{
    this.wasViewInitialized = true;
    this.refreshContent();
}
// wasViewInitialized is an IMPORTANT switch 
// when this component would have its own changing @Input()
// - then we have to wait till view is intialized - first OnChange is too soon
public ngOnChanges(changes: {[key: string]: SimpleChange}): void
{
    if (this.wasViewInitialized) {
        return;
    }
    this.refreshContent();
}

public ngOnDestroy(){
  if (this.componentRef) {
      this.componentRef.destroy();
      this.componentRef = null;
  }
}

done

That is pretty much it. Do not forget to Destroy anything what was built dynamically (ngOnDestroy). Also, be sure to cache dynamic types and modules if the only difference is their template.

What you want is maxlength.

Valid for text, search, url, tel, email, and password, it defines the maximum number of characters (as UTF-16 code units) the user can enter into the field. This must be an integer value 0 or higher. If no maxlength is specified, or an invalid value is specified, the field has no maximum length. This value must also be greater than or equal to the value of minlength.

You might consider using one of these input types.

Matching Anything but Given Strings

If you want to match the entire string where you want to match everything but certain strings you can do it like this:

^(?!(red|green|blue)$).*$

This says, start the match from the beginning of the string where it cannot start and end with red, green, or blue and match anything else to the end of the string.

You can try it here: https://regex101.com/r/rMbYHz/2

Note that this only works with regex engines that support a negative lookahead.

Or, to get a pseudo-random int in the range 0 to 19, for example, you could use the higher bits like this:

j = ((rand() >> 15) % 20;

Beware if your page is including other .jsp or .jspf (fragment)! If you don't set

<%@ page session="false" %>

on them as well, the parent page will end up starting a new session and setting the JSESSIONID cookie.

For .jspf pages in particular, this happens if you configured your web.xml with such a snippet:

<jsp-config>
    <jsp-property-group>
        <url-pattern>*.jspf</url-pattern>
    </jsp-property-group>
</jsp-config>

in order to enable scriptlets inside them.

According to Joshua Bloch's Effective Java (a book that can't be recommended enough, and which I bought thanks to continual mentions on stackoverflow):

The value 31 was chosen because it is an odd prime. If it were even and the multiplication overflowed, information would be lost, as multiplication by 2 is equivalent to shifting. The advantage of using a prime is less clear, but it is traditional. A nice property of 31 is that the multiplication can be replaced by a shift and a subtraction for better performance: 31 * i == (i << 5) - i. Modern VMs do this sort of optimization automatically.

(from Chapter 3, Item 9: Always override hashcode when you override equals, page 48)

1. Your code won't compile, it should be int [] theArray = new int[20];;
2. You can get the array length as theArray.length;
3. For primitive types, the array will be initialized with the default values (0 for int).

4. You can make it Integer [] theArray = new Integer[20]; and then count initialized members as this code does:

   public int count(Object [] array) {
       int c = 0;
       for(Object el: array) { if(el != null) c++; }
           return c;
   }
   

Please note that this answer isn't about why you may need this and what is the best way to do what you want.

There are a few characters which can indicate a new line. The usual ones are these two: '\n' or '0x0A' (10 in decimal) -> This character is called "Line Feed" (LF). '\r' or '0x0D' (13 in decimal) -> This one is called "Carriage return" (CR).

Different Operating Systems handle newlines in a different way. Here is a short list of the most common ones:

DOS and Windows

They expect a newline to be the combination of two characters, namely '\r\n' (or 13 followed by 10).

Unix (and hence Linux as well)

Unix uses a single '\n' to indicate a new line.

Mac

Macs use a single '\r'.

--- Create new config in signingConfigs

unsigned {
        //do not sign
    }

--- Create build type in buildTypes

unsigned {
        versionNameSuffix '-unsigned'
    }

--- Go to build variants and chose unsigned standard. Build project.

--- Go to "outputs/apk" and find "XXX-unsigned.apk". To check if it is unsigned try to install it to device - you'll fail.

tl;dr

cp -R "/src/project 1/App" "/src/project 2"

Explanation:

Using quotes will cater for spaces in the directory names

cp -R "/src/project 1/App" "/src/project 2"

If the App directory is specified in the destination directory:

cp -R "/src/project 1/App" "/src/project 2/App"

and "/src/project 2/App" already exists the result will be "/src/project 2/App/App"

Best not to specify the directory copied in the destination so that the command can be repeated over and over with the expected result.

Inside a bash script:

cp -R "${1}/App" "${2}"

This cannot be done in the fashion you are talking about. PHP is server-side while the form exists on the client-side. You will need to look into using JavaScript and/or Ajax if you don't want to refresh the page.

test.php

<form action="javascript:void(0);" method="post">
    <input type="text" name="user" placeholder="enter a text" />
    <input type="submit" value="submit" />
</form>

<script type="text/javascript">
    $("form").submit(function(){
        var str = $(this).serialize();
        $.ajax('getResult.php', str, function(result){
            alert(result); // The result variable will contain any text echoed by getResult.php
        }
        return(false);
    });
</script>

It will call getResult.php and pass the serialized form to it so the PHP can read those values. Anything getResult.php echos will be returned to the JavaScript function in the result variable back on test.php and (in this case) shown in an alert box.

getResult.php

<?php
    echo "The name you typed is: " . $_REQUEST['user'];
?>

NOTE

This example uses jQuery, a third-party JavaScript wrapper. I suggest you first develop a better understanding of how these web technologies work together before complicating things for yourself further.

How about this?

JSONObject jsonObject = new JSONObject           (YOUR_JSON_STRING);
JSONObject ipinfo     = jsonObject.getJSONObject ("ipinfo");
String     ip_address = ipinfo.getString         ("ip_address");
JSONObject location   = ipinfo.getJSONObject     ("Location");
String     latitude   = location.getString       ("latitude");
System.out.println (latitude);

This sample code using "org.json.JSONObject"

If you can support it CSS Grid is probably the cleanest way for making a one-dimensional list into a two column layout with responsive interiors.

ul {_x000D_
  max-width: 400px;_x000D_
  display: grid;_x000D_
  grid-template-columns: 50% 50%;_x000D_
  padding-left: 0;_x000D_
  border: 1px solid blue;_x000D_
}_x000D_
_x000D_
li {_x000D_
  list-style: inside;_x000D_
  border: 1px dashed red;_x000D_
  padding: 10px;_x000D_
}

<ul>_x000D_
  <li>1</li>_x000D_
  <li>2</li>_x000D_
  <li>3</li>_x000D_
  <li>4</li>_x000D_
  <li>5</li>_x000D_
  <li>6</li>_x000D_
  <li>7</li>_x000D_
  <li>8</li>_x000D_
  <li>9</li>_x000D_
<ul>

These are the two key lines which will give you your 2 column layout

display: grid;
grid-template-columns: 50% 50%;

Building on some of the responds here, i'd like to add an alternative way. Creating a generic method using reflection, that can map any Stored Procedure response to a List. That is, a List of any type you wish, as long as the given type contains similarly named members to the Stored Procedure columns in the response. Ideally, i'd probably use Dapper for this - but here goes:

private static SqlConnection getConnectionString() // Should be gotten from config in secure storage.
        {
            SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder();
            builder.DataSource = "it.hurts.when.IP";
            builder.UserID = "someDBUser";
            builder.Password = "someDBPassword";
            builder.InitialCatalog = "someDB";
            return new SqlConnection(builder.ConnectionString);
        }

        public static List<T> ExecuteSP<T>(string SPName, List<SqlParameter> Params)
        {
            try
            {
                DataTable dataTable = new DataTable();

                using (SqlConnection Connection = getConnectionString())
                {
                    // Open connection
                    Connection.Open();

                    SqlCommand cmd = new SqlCommand(SPName, Connection);

                    // Add parameters
                    cmd.Parameters.AddRange(Params.ToArray());
                    cmd.CommandType = CommandType.StoredProcedure;

                    // Make datatable for conversion
                    SqlDataAdapter da = new SqlDataAdapter(cmd);
                    da.Fill(dataTable);

In addition to the answer already accepted, for the scenario when you want to define a default property as a function of other properties you can use expression body notation on C#6.0 (and higher) for even more elegant and concise constructs like:

public class Person{

    public string FullName  => $"{First} {Last}"; // expression body notation

    public string First { get; set; } = "First";
    public string Last { get; set; } = "Last";
}

You can use the above in the following fashion

    var p = new Person();

    p.FullName; // First Last

    p.First = "Jon";
    p.Last = "Snow";

    p.FullName; // Jon Snow

In order to be able to use the above "=>" notation, the property must be read only, and you do not use the get accessor keyword.

I think I just discovered a way to apply overlapping conditions in the expected way using VBA. After hours of trying out different approaches I found that what worked was changing the "Applies to" range for the conditional format rule, after every single one was created!

This is my working example:

You can also overload the increment/decrement operators for your enumerated type.

enter image description here

I have a similar issue, which detail information as the first image.

My solution is that switch the certification always trust to use system defaults. just like: enter image description here enter image description here

Can I recommend to you to not use either?

If you want to "send" data to your screen, send a strongly typed object (A.K.A. ViewModel) because it's easier to test.

If you bind to some sort of "Model" and have random "viewbag" or "viewdata" items then it makes automated testing very difficult.

If you are using these consider how you might be able to restructure and just use ViewModels.

if you have a checkbox and you would like to fetch it's value ie true / false in any java file--

Use--

Context mContext;
boolean checkFlag;

checkFlag=PreferenceManager.getDefaultSharedPreferences(mContext).getBoolean(KEY,DEFAULT_VALUE);`

To break a condition use the return(0);

So, in your case it would be:

    if(x==1)
    {
        return 0;
    }

var userPasswordString = new Buffer(baseAuth, 'base64').toString('ascii');

Change this line from your code to this -

var userPasswordString = Buffer.from(baseAuth, 'base64').toString('ascii');

or in my case, I gave the encoding in reverse order

var userPasswordString = Buffer.from(baseAuth, 'utf-8').toString('base64');

DateFormat df = DateFormat.getDateTimeInstance(DateFormat.FULL, DateFormat.FULL);
df.setTimeZone(TimeZone.getTimeZone("PST"));
final String dateTimeString = df.format(new Date());

I use Windows Server 2012 for hosting for a long time and it just stop working after a more than years without any problem. My solution was to add public IP address of the server to list of relays and enabled Windows Integrated Authentication.

I just made two changes and I don't which help.

Go to IIS 6 Manager

Select properties of SMTP server

On tab Access, select Relays

Add your public IP address

Close the dialog and on the same tab click to Authentication button.

Add Integrated Windows Authentication

Maybe some step is not needed, but it works.

Bitmap scaledBitmap = scaleDown(realImage, MAX_IMAGE_SIZE, true);

Scale down method:

public static Bitmap scaleDown(Bitmap realImage, float maxImageSize,
        boolean filter) {
    float ratio = Math.min(
            (float) maxImageSize / realImage.getWidth(),
            (float) maxImageSize / realImage.getHeight());
    int width = Math.round((float) ratio * realImage.getWidth());
    int height = Math.round((float) ratio * realImage.getHeight());

    Bitmap newBitmap = Bitmap.createScaledBitmap(realImage, width,
            height, filter);
    return newBitmap;
}

var divID = "question-" + (parseInt(i)+1);

Use this + operator behave as concat that's why it showing 11.

Approach: calculate keys to remove, mutate dict

Let's call keys the list/iterator of keys that you are given to remove. I'd do this:

keys_to_remove = set(keys).intersection(set(mydict.keys()))
for key in keys_to_remove:
    del mydict[key]

You calculate up front all the affected items and operate on them.

Approach: calculate keys to keep, make new dict with those keys

I prefer to create a new dictionary over mutating an existing one, so I would probably also consider this:

keys_to_keep = set(mydict.keys()) - set(keys)
new_dict = {k: v for k, v in mydict.iteritems() if k in keys_to_keep}

or:

keys_to_keep = set(mydict.keys()) - set(keys)
new_dict = {k: mydict[k] for k in keys_to_keep}

find . -mindepth 1 -maxdepth 1 -type d -printf "%P\n"

It’s about time someone provides the modern answer to this question. In 2012 when the question was asked, the answers also posted back then were good answers. Why the answers posted in 2016 also use the then long outdated classes SimpleDateFormat and Date is a bit more of a mystery to me. java.time, the modern Java date and time API also known as JSR-310, is so much nicer to work with. You can use it on Android through the ThreeTenABP, see this question: How to use ThreeTenABP in Android Project.

For most purposes I recommend using the milliseconds since the epoch at the start of the day in UTC. To obtain these:

    DateTimeFormatter dateFormatter
            = DateTimeFormatter.ofPattern("d-MMMM-uuuu", Locale.ENGLISH);
    String stringDate = "12-December-2012";
    long millisecondsSinceEpoch = LocalDate.parse(stringDate, dateFormatter)
            .atStartOfDay(ZoneOffset.UTC)
            .toInstant()
            .toEpochMilli();
    System.out.println(millisecondsSinceEpoch);

This prints:

1355270400000

If you require the time at start of day in some specific time zone, specify that time zone instead of UTC, for example:

            .atStartOfDay(ZoneId.of("Asia/Karachi"))

As expected this gives a slightly different result:

1355252400000

Another point to note, remember to supply a locale to your DateTimeFormatter. I took December to be English, there are other languages where that month is called the same, so please choose the proper locale yourself. If you didn’t provide a locale, the formatter would use the JVM’s locale setting, which may work in many cases, and then unexpectedly fail one day when you run your app on a device with a different locale setting.

Try this Toggle Buttons

test_activity.xml

<ToggleButton 
android:id="@+id/togglebutton" 
android:layout_width="100px" 
android:layout_height="50px" 
android:layout_centerVertical="true" 
android:layout_centerHorizontal="true"
android:onClick="toggleclick"/>

Test.java

public class Test extends Activity {

private ToggleButton togglebutton;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    togglebutton = (ToggleButton) findViewById(R.id.togglebutton);
}

public void toggleclick(View v){
    if(togglebutton.isChecked())
        Toast.makeText(TestActivity.this, "ON", Toast.LENGTH_SHORT).show();
    else
        Toast.makeText(TestActivity.this, "OFF", Toast.LENGTH_SHORT).show();
    }
}

You should use a List for something like this, not an array. As a general rule of thumb, when you don't know how many elements you will add to an array before hand, use a List instead. Most would probably tackle this problem by using an ArrayList.

If you really can't use a List, then you'll probably have to use an array of some initial size (maybe 10?) and keep track of your array capacity versus how many elements you're adding, and copy the elements to a new, larger array if you run out of room (this is essentially what ArrayList does internally). Also note that, in the real world, you would never do it this way - you would use one of the standard classes that are made specifically for cases like this, such as ArrayList.

Adding "-EA Stop" solved this for me.

I came to this post when i was searching for the same issue but in android. I don't say this is the best way to get sorted files by last modified date, but its the easiest way I found yet.

Below code may be helpful to someone-

File downloadDir = new File("mypath");    
File[] list = downloadDir.listFiles();
    for (int i = list.length-1; i >=0 ; i--) {
        //use list.getName to get the name of the file
    }

Thanks

Have you noticed that you don't get the error if you run

python ./script.py

instead of

python script.py

This is because sys.argv[0] will read ./script.py in the former case, which gives os.path.dirname something to work with. When you don't specify a path, sys.argv[0] reads simply script.py, and os.path.dirname cannot determine a path.

Here is what worked for me:

const fsp = require('fs-promise');

(async () => {
  try {
    const names = await fsp.readdir('path/to/dir');
    console.log(names[0]);
  } catch (e) {
    console.log('error: ', e);
  }
})();

This code works in node 7.6 without babel when harmony flag is enabled: node --harmony my-script.js. And starting with node 7.7, you don't even need this flag!

The fsp library included in the beginning is just a promisified wrapper for fs (and fs-ext).

I’m really exited about what you can do in node without babel these days! Native async/await make writing code such a pleasure!

UPDATE 2017-06: fs-promise module was deprecated. Use fs-extra instead with the same API.

 SELECT * FROM all_procedures WHERE OBJECT_TYPE IN ('FUNCTION','PROCEDURE','PACKAGE') 
 and owner = 'Schema_name' order by object_name

here 'Schema_name' is a name of schema, example i have a schema named PMIS, so the example will be

SELECT * FROM all_procedures WHERE OBJECT_TYPE IN ('FUNCTION','PROCEDURE','PACKAGE') 
and owner = 'PMIS' order by object_name

Ref: https://www.plsql.co/list-all-procedures-from-a-schema-of-oracle-database.html

Don't use the word "click" as the function name. It's a reserved keyword in JavaScript. In the bellow code I’ve used "hello" function instead of "click"

<html>
<head>
    <title>Space Clicker</title>
</head>

<body>
    <script type="text/javascript">

    var clicks = 0;
    function hello() {
        clicks += 1;
        document.getElementById("clicks").innerHTML = clicks;
    };
    </script>
    <button type="button" onclick="hello()">Click me</button>
    <p>Clicks: <a id="clicks">0</a></p>

</body></html>

While converting a STD class object to array.Cast the object to array by using array function of php.

Try out with following code snippet.

/*** cast the object ***/    
foreach($stdArray as $key => $value)
{
    $stdArray[$key] = (array) $value;
}   
/*** show the results ***/  
print_r( $stdArray );

You could also supply variables on the command line with -PmavenUser=user -PmavenPassword=password.

This might be useful you can't use a gradle.properties file for some reason. E.g. on a build server we're using Gradle with the -g option so that each build plan has it's own GRADLE_HOME.

So is there any other method to achieve this goal?

No. In order to convert an image to a byte array you have to specify an image format - just as you have to specify an encoding when you convert text to a byte array.

If you're worried about compression artefacts, pick a lossless format. If you're worried about CPU resources, pick a format which doesn't bother compressing - just raw ARGB pixels, for example. But of course that will lead to a larger byte array.

Note that if you pick a format which does include compression, there's no point in then compressing the byte array afterwards - it's almost certain to have no beneficial effect.

In case someone is still looking for a solution for this, the following plugin does the job http://mohammadyounes.github.io/jquery-scrollLock/

It fully addresses the issue of locking mouse wheel scroll inside a given container, preventing it from propagating to parent element.

It does not change wheel scrolling speed, user experience will not be affected. and you get the same behavior regardless of the OS mouse wheel vertical scrolling speed (On Windows it can be set to one screen or one line up to 100 lines per notch).

CSV is a standard format, outlined in RFC 4180 (in 2005), so there IS no lack of a standard. https://www.ietf.org/rfc/rfc4180.txt

And even before that, the C in CSV has always stood for Comma, not for semiColon :(

It's a pity Microsoft keeps ignoring that and is still sticking to the monstrosity they turned it into decades ago (yes, I admit, that was before the RFC was created).

• One record per line, unless a newline occurs within quoted text (see below).
• COMMA as column separator. Never a semicolon.
• PERIOD as decimal point in numbers. Never a comma.
• Text containing commas, periods and/or newlines enclosed in "double quotation marks".

• Only if text is enclosed in double quotation marks, such quotations marks in the text escaped by doubling. These examples represent the same three fields:

  1,"this text contains ""quotation marks""",3

  1,this text contains "quotation marks",3

The standard does not cover date and time values, personally I try to stick to ISO 8601 format to avoid day/month/year -- month/day/year confusion.

With text files, maybe the EOF is -1 when using BufferReader.read(), char by char. I made a test with BufferReader.readLine()!=null and it worked properly.

that issue is because jersey can't find a dependecy package for your rest service declarated

check your project package distribution and assert that is equals to your web.xml param value

taskkill /f /im "devenv.exe"

this will forcibly kill the pid with the exe name "devenv.exe"

equivalent to -9 on the nix'y kill command

Use the onsubmit event to execute JavaScript code when the form is submitted. You can then return false or call the passed event's preventDefault method to disable the form submission.

For example:

<script>
function doSomething() {
    alert('Form submitted!');
    return false;
}
</script>

<form onsubmit="return doSomething();" class="my-form">
    <input type="submit" value="Submit">
</form>

This works, but it's best not to litter your HTML with JavaScript, just as you shouldn't write lots of inline CSS rules. Many Javascript frameworks facilitate this separation of concerns. In jQuery you bind an event using JavaScript code like so:

<script>
$('.my-form').on('submit', function () {
    alert('Form submitted!');
    return false;
});
</script>

<form class="my-form">
    <input type="submit" value="Submit">
</form>

We can try

iris %>% 
      select_(.dots= setdiff(names(.),drop.cols))

In recent version, The following works fine:

    $('.selector').datetimepicker({
        maxDate: new Date()
    });

maxDate accepts a Date object as parameter.

The following found in documentation:

Multiple types supported:

• Date: A date object containing the minimum date.

• Number: A number of days from today. For example 2 represents two days from today and -1 represents yesterday.

• String: A string in the format defined by the dateFormat option, or a relative date. Relative dates must contain value and period pairs; valid periods are "y" for years, "m" for months, "w" for weeks, and "d" for days. For example, "+1m +7d" represents one month and seven days from today.

Try renaming the default file. In my case, a recent move to IIS7.5 gave the 405 error. I changed index.aspx to default.aspx and it worked immediately for me.

You can try the following code:

import java.time.*;

public class Test{
   public static void main(String[] args) {
      DayOfWeek dow = LocalDate.of(2010,Month.FEBRUARY,23).getDayOfWeek();
      String s = String.valueOf(dow);
      System.out.println(String.format("%.3s",s));
   }
}

All of

std::string s(1, c); std::cout << s << std::endl;

and

std::cout << std::string(1, c) << std::endl;

and

std::string s; s.push_back(c); std::cout << s << std::endl;

worked for me.

This is similar to the difference between

SELECT * FROM table_name and SELECT 1 FROM table_name.  

If you do

SELECT 1 FROM table_name

it will give you the number 1 for each row in the table. So yes count(*) and count(1) will provide the same results as will count(8) or count(column_name)

Best ways to get property values are using.

1. Using Value annotation

@Value("${property.key}")
private String propertyKeyVariable;

2. Using Enviornment bean

@Autowired
private Environment env;

public String getValue() {
    return env.getProperty("property.key");
}

public void display(){
  System.out.println("# Value : "+getValue);
}

you just need to use word boundary (\b) instead of ^ and $:

\bgarp\b

I have had a similar problem with a WPF application that gets invoked from an Access application via the Shell object.

My solution is below - works in XP and Win7 x64 with app compiled to x86 target.

I'd much rather do this than simulate an alt-tab.

void Window_Loaded(object sender, RoutedEventArgs e)
{
    // make sure the window is normal or maximised
    // this was the core of the problem for me;
    // even though the default was "Normal", starting it via shell minimised it
    this.WindowState = WindowState.Normal;

    // only required for some scenarios
    this.Activate();
}

I had a Automated Billing setup online and the credit card said it say good Thru 10/09, but the card was rejected the first week in October and again the next week. Each time it was rejected it cost me a $10 fee. Don't assume it good thru the end of the month if you have automatic billing setup.

Here's what i do to FORCE UNLOCK FOR some locked tables in MySQL

1) Enter MySQL

mysql -u your_user -p

2) Let's see the list of locked tables

mysql> show open tables where in_use>0;

3) Let's see the list of the current processes, one of them is locking your table(s)

mysql> show processlist;

4) Let's kill one of these processes

mysql> kill put_process_id_here;

Add this code after the onCreate ,method in your activity containing the WebView

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);    
}

@Override
protected void onRestoreInstanceState(Bundle state) {
    super.onRestoreInstanceState(state);    
}

Just add

position: relative;
top: 50%;
transform: translateY(-50%);

to the inner div.

What it does is moving the inner div's top border to the half height of the outer div (top: 50%;) and then the inner div up by half its height (transform: translateY(-50%)). This will work with position: absolute or relative.

Keep in mind that transform and translate have vendor prefixes which are not included for simplicity.

Should be pretty straightforward, its just the reverse of your previous method;

public static int GetEnumFromDescription(string description, Type enumType)
{
    foreach (var field in enumType.GetFields())
    {
        DescriptionAttribute attribute
            = Attribute.GetCustomAttribute(field, typeof(DescriptionAttribute))as DescriptionAttribute;
        if(attribute == null)
            continue;
        if(attribute.Description == description)
        {
            return (int) field.GetValue(null);
        }
    }
    return 0;
}

Usage:

Console.WriteLine((Animal)GetEnumFromDescription("Giant Panda",typeof(Animal)));

I have tried several solutions proposed above without success.

So, I have installed the last ruby version 2.7.2 with rbenv, and upgraded my app.

Then I had a PG::ConnectionBad error.

I ran

brew postgresql-upgrade-database.

And now It’s working fine.

here more details about what I tried.

To give a URL to an image tag which locates images/ directory in the root like

`logo.png`

you should give src URL starting with / as follows:

<img src="/images/logo.png"/>

This code works in any directories without any troubles even if you are in branches/europe/about.php still the logo can be seen right there.

Off the top of my head, one way would be to grab all previous elements and count them.

$('td').click(function(){ 
    var colIndex = $(this).prevAll().length;
    var rowIndex = $(this).parent('tr').prevAll().length;
});

You can't create array of generic type. Create List of ArrayLists :

 List<ArrayList<Individual>> group = new ArrayList<ArrayList<Individual>>();

or if you REALLY need array (WARNING: bad design!):

 ArrayList[] group = new ArrayList[4];

Tried printf(1)?

printf "%x\n" 34
22

There are probably ways of doing that with builtin functions in all shells but it would be less portable. I've not checked the POSIX sh specs to see whether it has such capabilities.

You should use setState function. If not, state won't save your change, no matter how you use forceUpdate.

Container {
    handleEvent= () => { // use arrow function
        //this.props.foo.bar = 123
        //You should use setState to set value like this:
        this.setState({foo: {bar: 123}});
    };

    render() {
        return <Child bar={this.state.foo.bar} />
    }
    Child {
        render() {
            return <div>{this.props.bar}</div>
        }
    }
}

Your code seems not valid. I can not test this code.

You can also initialise it like this:

struct name sara = { "Sara", "Black" };

Since (as a special case) you're allowed to initialise char arrays from string constants.

Now, as for what a struct actually is - it's a compound type composed of other values. What sara actually looks like in memory is a block of 20 consecutive char values (which can be referred to using sara.first, followed by 0 or more padding bytes, followed by another block of 20 consecutive char values (which can be referred to using sara.last). All other instances of the struct name type are laid out in the same way.

In this case, it is very unlikely that there is any padding, so a struct name is just a block of 40 characters, for which you have a name for the first 20 and the last 20.

You can find out how big a block of memory a struct name takes using sizeof(struct name), and you can find out where within that block of memory each member of the structure is placed at using offsetof(struct name, first) and offsetof(struct name, last).

if your question is "how to bind events on ajax loaded content" you can do like this :

$("img.lazy").lazyload({
    effect : "fadeIn",
    event: "scrollstop",
    skip_invisible : true
}).removeClass('lazy');

// lazy load to DOMNodeInserted event
$(document).bind('DOMNodeInserted', function(e) {
    $("img.lazy").lazyload({
        effect : "fadeIn",
        event: "scrollstop",
        skip_invisible : true
    }).removeClass('lazy');
});

so you don't need to place your configuration to every you ajax code

print(link_addres.contents[0])

It will print the context of the anchor tags

example:

 statement_title = statement.find('h2',class_='briefing-statement__title')
 statement_title_text = statement_title.a.contents[0]

In traditional terminology, Ruby is strictly pass-by-value. But that's not really what you're asking here.

Ruby doesn't have any concept of a pure, non-reference value, so you certainly can't pass one to a method. Variables are always references to objects. In order to get an object that won't change out from under you, you need to dup or clone the object you're passed, thus giving an object that nobody else has a reference to. (Even this isn't bulletproof, though — both of the standard cloning methods do a shallow copy, so the instance variables of the clone still point to the same objects that the originals did. If the objects referenced by the ivars mutate, that will still show up in the copy, since it's referencing the same objects.)

You should only access Linux files system (those located in lxss folder) from inside WSL; DO NOT create/modify any files in lxss folder in Windows - it's dangerous and WSL will not see these files.

Files can be shared between WSL and Windows, though; put the file outside of lxss folder. You can access them via drvFS (/mnt) such as /mnt/c/Users/yourusername/files within WSL. These files stay synced between WSL and Windows.

For details and why, see: https://blogs.msdn.microsoft.com/commandline/2016/11/17/do-not-change-linux-files-using-windows-apps-and-tools/

HTTPS proxy doesn't make sense because you can't terminate your HTTP connection at the proxy for security reasons. With your trust policy, it might work if the proxy server has a HTTPS port. Your error is caused by connecting to HTTP proxy port with HTTPS.

You can connect through a proxy using SSL tunneling (many people call that proxy) using proxy CONNECT command. However, Java doesn't support newer version of proxy tunneling. In that case, you need to handle the tunneling yourself. You can find sample code here,

http://www.javaworld.com/javaworld/javatips/jw-javatip111.html

EDIT: If you want defeat all the security measures in JSSE, you still need your own TrustManager. Something like this,

 public SSLTunnelSocketFactory(String proxyhost, String proxyport){
      tunnelHost = proxyhost;
      tunnelPort = Integer.parseInt(proxyport);
      dfactory = (SSLSocketFactory)sslContext.getSocketFactory();
 }

 ...

 connection.setSSLSocketFactory( new SSLTunnelSocketFactory( proxyHost, proxyPort ) );
 connection.setDefaultHostnameVerifier( new HostnameVerifier()
 {
    public boolean verify( String arg0, SSLSession arg1 )
    {
        return true;
    }
 }  );

EDIT 2: I just tried my program I wrote a few years ago using SSLTunnelSocketFactory and it doesn't work either. Apparently, Sun introduced a new bug sometime in Java 5. See this bug report,

http://bugs.sun.com/view_bug.do?bug_id=6614957

The good news is that the SSL tunneling bug is fixed so you can just use the default factory. I just tried with a proxy and everything works as expected. See my code,

public class SSLContextTest {

    public static void main(String[] args) {

        System.setProperty("https.proxyHost", "proxy.xxx.com");
        System.setProperty("https.proxyPort", "8888");

        try {

            SSLContext sslContext = SSLContext.getInstance("SSL");

            // set up a TrustManager that trusts everything
            sslContext.init(null, new TrustManager[] { new X509TrustManager() {
                public X509Certificate[] getAcceptedIssuers() {
                    System.out.println("getAcceptedIssuers =============");
                    return null;
                }

                public void checkClientTrusted(X509Certificate[] certs,
                        String authType) {
                    System.out.println("checkClientTrusted =============");
                }

                public void checkServerTrusted(X509Certificate[] certs,
                        String authType) {
                    System.out.println("checkServerTrusted =============");
                }
            } }, new SecureRandom());

            HttpsURLConnection.setDefaultSSLSocketFactory(
                    sslContext.getSocketFactory());

            HttpsURLConnection
                    .setDefaultHostnameVerifier(new HostnameVerifier() {
                        public boolean verify(String arg0, SSLSession arg1) {
                            System.out.println("hostnameVerifier =============");
                            return true;
                        }
                    });

            URL url = new URL("https://www.verisign.net");
            URLConnection conn = url.openConnection();
            BufferedReader reader = 
                new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } 
    }
}

This is what I get when I run the program,

checkServerTrusted =============
hostnameVerifier =============
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
......

As you can see, both SSLContext and hostnameVerifier are getting called. HostnameVerifier is only involved when the hostname doesn't match the cert. I used "www.verisign.net" to trigger this.

Double underscore. That mangles the name. The variable can still be accessed, but it's generally a bad idea to do so.

Use single underscores for semi-private (tells python developers "only change this if you absolutely must") and doubles for fully private.

window.resizeBy() will trigger window's onresize event. This works in both Javascript or VBScript.

window.resizeBy(xDelta, yDelta) called like window.resizeBy(-200, -200) to shrink page 200px by 200px.

I had the same need in bash (Ubuntu 16.04 LTS) and the commands provided in the answers failed to work in my case. I had to use:

curl -X POST -F 'username="$USER"' -F 'password="$PASS"' "http://api.somesite.com/test/blah?something=123"

Double quotes in the -F arguments are only needed if you're using variables, thus from the command line ... -F 'username=myuser' ... will be fine.

Relevant Security Notice: as Mr. Mark Ribau points in comments this command shows the password ($PASS variable, expanded) in the processlist!

For me it was as easy as deleting the local branch again, since I didn't have any local commits that I wanted to push:

So I did:

git branch -d branchname

And then checking the branch out again:

git checkout branchname

Visual Studio 2017 version 15.8 made it possible to use the PackageReferencesyntax to reference NuGet packages in Visual Studio Extensibility (VSIX) projects. This makes it much simpler to reason about NuGet packages and opens the door for having a complete meta package containing the entire VSSDK.

Installing below NuGet package will solve the EmbedInteropTypes Issue.

Install-Package Microsoft.VisualStudio.SDK.EmbedInteropTypes

This works for all cases.

function resizeImg(imgId) {
    var img = document.getElementById(imgId);
    var $img = $(img);
    var maxWidth = 110;
    var maxHeight = 100;
    var width = img.width;
    var height = img.height;
    var aspectW = width / maxWidth;
    var aspectH = height / maxHeight;

    if (aspectW > 1 || aspectH > 1) {
        if (aspectW > aspectH) {
            $img.width(maxWidth);
            $img.height(height / aspectW);
        }
        else {
            $img.height(maxHeight);
            $img.width(width / aspectH);
        }
    }
}

Sure. On my (pretty vanilla) Cygwin setup, bash is in c:\cygwin\bin so I can run a bash script (say testit.sh) from a Windows batch file using a command like:

C:\cygwin\bin\bash testit.sh

... which can be included in a .bat file as easily as it can be typed at the command line, and with the same effect.

if you are in dev mode with not valid certificate, why not just set weClient.setUseInsecureSSL(true). works for me

Generally, make an "inverse" commit, using:

git revert 364705c

then send it to the remote as usual:

git push

This won't delete the commit: it makes an additional commit that undoes whatever the first commit did. Anything else, not really safe, especially when the changes have already been propagated.

Please try this one option:

 task RunTest(type: Test) {
         systemProperty "spring.profiles.active", System.getProperty("DEV")
         include 'com/db/project/Test1.class'
     }

I know it's an older post, but i wanna add some extra informations about that. Firstly, i think that rvm does great BUT it wasn't updating ruby from my system (MAC OS Yosemite).

What rvmwas doing : installing to another location and setting up the path there to my environment variable ... And i was kinda bored, because i had two ruby now on my system.

So to fix that, i uninstalled the rvm, then used the Homebrew package manager available here and installed ruby throw terminal command by doing brew install ruby.

And then, everything was working perfectly ! The ruby from my system was updated ! Hope it will help for the next adventurers !

I also faced similar problem while working on Affable Bean e-commerce site development. I received an error:

Although it is much easier to restore database using SSMS as stated in many answers. You can also restore Database using .bak with SQL server query, for example

RESTORE DATABASE AdventureWorks2012 FROM DISK = 'D:\AdventureWorks2012.BAK'
GO

In above Query you need to keep in mind about .mdf/.ldf file location. You might get error

System.Data.SqlClient.SqlError: Directory lookup for the file "C:\PROGRAM FILES\MICROSOFT SQL SERVER\MSSQL.1\MSSQL\DATA\AdventureWorks.MDF" failed with the operating system error 3(The system cannot find the path specified.). (Microsoft.SqlServer.SmoExtended)

So you need to run Query as below

RESTORE FILELISTONLY 
FROM DISK = 'D:\AdventureWorks2012.BAK'

Once you will run above Query you will get location of mdf/ldf use it Restore database using query

USE MASTER
GO
RESTORE DATABASE DBASE 
FROM DISK = 'D:\AdventureWorks2012.BAK'
WITH 
MOVE 'DBASE' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBASE\MSSQL\DATA\DBASE.MDF',
MOVE 'DBASE_LOG' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBASE\MSSQL\DATA\DBASE_1.LDF', 
NOUNLOAD,  REPLACE,  NOUNLOAD,  STATS = 5
GO

I would go for the second, the token system.

Did you know about ember-auth or ember-simple-auth? They both use the token based system, like ember-simple-auth states:

A lightweight and unobtrusive library for implementing token based authentication in Ember.js applications. http://ember-simple-auth.simplabs.com

They have session management, and are easy to plug into existing projects too.

There is also an Ember App Kit example version of ember-simple-auth: Working example of ember-app-kit using ember-simple-auth for OAuth2 authentication.

I understand this is an older question, but I would like to add another disadvantage of Single Page Applications:

If you build an API that returns results in a data language (such as XML or JSON) rather than a formatting language (like HTML), you are enabling greater application interoperability, for example, in business-to-business (B2B) applications. Such interoperability has great benefits but does allow people to write software to "mine" (or steal) your data. This particular disadvantage is common to all APIs that use a data language, and not to SPAs in general (indeed, an SPA that asks the server for pre-rendered HTML avoids this, but at the expense of poor model/view separation). This risk exposed by this disadvantage can be mitigated by various means, such as request limiting and connection blocking, etc.

Open Terminal and type:

pip config set global.target /Users/Bob/Library/Python/3.8/lib/python/site-packages

except instead of

/Users/Bob/Library/Python/3.8/lib/python/site-packages

you would use whatever directory you want.

It is also good to set the access security - just replace * with the domain you want to be able to reach it.

<?php
header('Access-Control-Allow-Origin: *');
header('Content-type: application/json');
    $response = array();
    $response[0] = array(
        'id' => '1',
        'value1'=> 'value1',
        'value2'=> 'value2'
    );

echo json_encode($response); 
?>

Here is more samples on that: how to bypass Access-Control-Allow-Origin?

Try the following:

<c:set var="count" value="0" scope="page" />

//in your loops
<c:set var="count" value="${count + 1}" scope="page"/>

This came up in a search I was just doing, found a better solution with some more searching, IPython notebooks now have a %%latex magic that makes the whole cell Latex without the $$ wrapper for each line.

Hi For jQuery You can only use like this

Use async and type="text/javascript" only

You'll have to use the ChannelFactory class.

Here's an example:

var myBinding = new BasicHttpBinding();
var myEndpoint = new EndpointAddress("http://localhost/myservice");
using (var myChannelFactory = new ChannelFactory<IMyService>(myBinding, myEndpoint))
{
    IMyService client = null;

    try
    {
        client = myChannelFactory.CreateChannel();
        client.MyServiceOperation();
        ((ICommunicationObject)client).Close();
        myChannelFactory.Close();
    }
    catch
    {
        (client as ICommunicationObject)?.Abort();
    }
}

• How to: Use the ChannelFactory

with 5 columns and colspan, this is possible (click here) (but doesn't make much sense to me):

<table width="100%" border="1" bgcolor="#ffffff">
    <colgroup>
        <col width="25%">
        <col width="25%">
        <col width="25%">
        <col width="5%">
        <col width="20%">
    </colgroup>

        <td>25</td>
        <td colspan="2">50</td>
        <td colspan="2">25</td>     
    </tr>
    <tr>
        <td colspan="2">50</td>
        <td colspan="2">30</td>
        <td>20</td>
    </tr>
</table>

What I tend to do, and I believe this is what Google intended for developers to do too, is to still get the extras from an Intent in an Activity and then pass any extra data to fragments by instantiating them with arguments.

There's actually an example on the Android dev blog that illustrates this concept, and you'll see this in several of the API demos too. Although this specific example is given for API 3.0+ fragments, the same flow applies when using FragmentActivity and Fragment from the support library.

You first retrieve the intent extras as usual in your activity and pass them on as arguments to the fragment:

public static class DetailsActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // (omitted some other stuff)

        if (savedInstanceState == null) {
            // During initial setup, plug in the details fragment.
            DetailsFragment details = new DetailsFragment();
            details.setArguments(getIntent().getExtras());
            getSupportFragmentManager().beginTransaction().add(
                    android.R.id.content, details).commit();
        }
    }
}

In stead of directly invoking the constructor, it's probably easier to use a static method that plugs the arguments into the fragment for you. Such a method is often called newInstance in the examples given by Google. There actually is a newInstance method in DetailsFragment, so I'm unsure why it isn't used in the snippet above...

Anyways, all extras provided as argument upon creating the fragment, will be available by calling getArguments(). Since this returns a Bundle, its usage is similar to that of the extras in an Activity.

public static class DetailsFragment extends Fragment {
    /**
     * Create a new instance of DetailsFragment, initialized to
     * show the text at 'index'.
     */
    public static DetailsFragment newInstance(int index) {
        DetailsFragment f = new DetailsFragment();

        // Supply index input as an argument.
        Bundle args = new Bundle();
        args.putInt("index", index);
        f.setArguments(args);

        return f;
    }

    public int getShownIndex() {
        return getArguments().getInt("index", 0);
    }

    // (other stuff omitted)

}

You can use the DISTINCT keyword within the COUNT aggregate function:

SELECT COUNT(DISTINCT column_name) AS some_alias FROM table_name

This will count only the distinct values for that column.

Because System.exit() is just another method to the compiler. It doesn't read ahead and figure out that the whole program will quit at that point (the JVM quits). Your OS or shell can read the integer that is passed back in the System.exit() method. It is standard for 0 to mean "program quit and everything went OK" and any other value to notify an error occurred. It is up to the developer to document these return values for any users.

return on the other hand is a reserved key word that the compiler knows well. return returns a value and ends the current function's run moving back up the stack to the function that invoked it (if any). In your code above it returns void as you have not supplied anything to return.

window.onclick = e => {
    console.dir(e.target);  // use this in chrome
    console.log(e.target);  // use this in firefox - click on tag name to view 
}  

take advantage of using filter propeties

e.target.tagName
e.target.className
e.target.style.height  // its not the value applied from the css style sheet, to get that values use `getComputedStyle()`

The override keyword serves two purposes:

1. It shows the reader of the code that "this is a virtual method, that is overriding a virtual method of the base class."
2. The compiler also knows that it's an override, so it can "check" that you are not altering/adding new methods that you think are overrides.

To explain the latter:

class base
{
  public:
    virtual int foo(float x) = 0; 
};


class derived: public base
{
   public:
     int foo(float x) override { ... } // OK
}

class derived2: public base
{
   public:
     int foo(int x) override { ... } // ERROR
};

In derived2 the compiler will issue an error for "changing the type". Without override, at most the compiler would give a warning for "you are hiding virtual method by same name".

string _connString = "metadata=res://*/Model.csdl|res://*/Model.ssdl|res://*/Model.msl;provider=System.Data.SqlClient;provider connection string="data source=localhost;initial catalog=DATABASE;persist security info=True;user id=sa;password=YourPassword;multipleactiveresultsets=True;App=EntityFramework"";

EntityConnectionStringBuilder ecsb = new EntityConnectionStringBuilder(_connString);
ctx = new Entities(_connString);

You can get the connection string from the web.config, and just set that in the EntityConnectionStringBuilder constructor, and use the EntityConnectionStringBuilder as an argument in the constructor for the context.

Cache the connection string by username. Simple example using a couple of generic methods to handle adding/retrieving from cache.

private static readonly ObjectCache cache = MemoryCache.Default;

// add to cache
AddToCache<string>(username, value);

// get from cache

 string value = GetFromCache<string>(username);
 if (value != null)
 {
     // got item, do something with it.
 }
 else
 {
    // item does not exist in cache.
 }


public void AddToCache<T>(string token, T item)
    {
        cache.Add(token, item, DateTime.Now.AddMinutes(1));
    }

public T GetFromCache<T>(string cacheKey) where T : class
    {
        try
        {
            return (T)cache[cacheKey];
        }
        catch
        {
            return null;
        }
    }

In the hexadecimal it can't get a negative value. So it shows it like ffffffff.

The advantage to using the unsigned version (when you know the values contained will be non-negative) is that sometimes the computer will spot errors for you (the program will "crash" when a negative value is assigned to the variable).

All the previous solutions seem to be overly complicated for what I think you need, and often didn't work for me. The following one-line command does what you want:

import os
ROOT_DIR = os.path.abspath(os.curdir)

Using one-to-many relation (FK from Friend to parent class) will make your app more scalable (as you can trivially extend the Friend object with additional attributes beyond the simple name). And thus this is the best way

You should write :

if (self.a != 0) and (self.b != 0) :

"&" is the bit wise operator and does not suit for boolean operations. The equivalent of "&&" is "and" in Python.

A shorter way to check what you want is to use the "in" operator :

if 0 not in (self.a, self.b) :

You can check if anything is part of a an iterable with "in", it works for :

• Tuples. I.E : "foo" in ("foo", 1, c, etc) will return true
• Lists. I.E : "foo" in ["foo", 1, c, etc] will return true
• Strings. I.E : "a" in "ago" will return true
• Dict. I.E : "foo" in {"foo" : "bar"} will return true

As an answer to the comments :

Yes, using "in" is slower since you are creating an Tuple object, but really performances are not an issue here, plus readability matters a lot in Python.

For the triangle check, it's easier to read :

0 not in (self.a, self.b, self.c)

Than

(self.a != 0) and (self.b != 0) and (self.c != 0) 

It's easier to refactor too.

Of course, in this example, it really is not that important, it's very simple snippet. But this style leads to a Pythonic code, which leads to a happier programmer (and losing weight, improving sex life, etc.) on big programs.

Here's a cool and scalable design pattern that runs in O(n) time ...

a = [1,2,3,4,5,6,7,6,5,4,3,2,1]

replacements = {
    1: 10,
    2: 20,
    3: 30,
}

a = [replacements.get(x, x) for x in a]

print(a)
# Returns [10, 20, 30, 4, 5, 6, 7, 6, 5, 4, 30, 20, 10]

The OP needed to cast as string outside the {% set ... %}. But if that not your case you can do:

{% set curYear = 2013 | string() %}

Note that you need the parenthesis on that jinja filter.

If you're concatenating 2 variables, you can also use the ~ custom operator.

To center align text

input[type='text'] { text-align:center;}

To center align the textbox in the container that it sits in, apply text-align:center to the container.

As mentioned above, you need the autoreload extension. If you want it to automatically start every time you launch ipython, you need to add it to the ipython_config.py startup file:

It may be necessary to generate one first:

ipython profile create

Then include these lines in ~/.ipython/profile_default/ipython_config.py:

c.InteractiveShellApp.exec_lines = []
c.InteractiveShellApp.exec_lines.append('%load_ext autoreload')
c.InteractiveShellApp.exec_lines.append('%autoreload 2')

As well as an optional warning in case you need to take advantage of compiled Python code in .pyc files:

c.InteractiveShellApp.exec_lines.append('print "Warning: disable autoreload in ipython_config.py to improve performance." ')

edit: the above works with version 0.12.1 and 0.13

One thing you should know is $ prefix refers to an Angular Method, $$ prefixes refers to angular methods that you should avoid using.

below is an example template and its controllers, we'll explore how $broadcast/$on can help us achieve what we want.

<div ng-controller="FirstCtrl">
    <input ng-model="name"/> 
    <button ng-click="register()">Register </button>
</div>

<div ng-controller="SecondCtrl">
    Registered Name: <input ng-model="name"/> 
</div>

The controllers are

app.controller('FirstCtrl', function($scope){
    $scope.register = function(){

    }
});

app.controller('SecondCtrl', function($scope){

});

My question to you is how do you pass the name to the second controller when a user clicks register? You may come up with multiple solutions but the one we're going to use is using $broadcast and $on.

$broadcast vs $emit

Which should we use? $broadcast will channel down to all the children dom elements and $emit will channel the opposite direction to all the ancestor dom elements.

The best way to avoid deciding between $emit or $broadcast is to channel from the $rootScope and use $broadcast to all its children. Which makes our case much easier since our dom elements are siblings.

Adding $rootScope and lets $broadcast

app.controller('FirstCtrl', function($rootScope, $scope){
    $scope.register = function(){
        $rootScope.$broadcast('BOOM!', $scope.name)
    }
});

Note we added $rootScope and now we're using $broadcast(broadcastName, arguments). For broadcastName, we want to give it a unique name so we can catch that name in our secondCtrl. I've chosen BOOM! just for fun. The second arguments 'arguments' allows us to pass values to the listeners.

Receiving our broadcast

In our second controller, we need to set up code to listen to our broadcast

app.controller('SecondCtrl', function($scope){
  $scope.$on('BOOM!', function(events, args){
    console.log(args);
    $scope.name = args; //now we've registered!
  })
});

It's really that simple. Live Example

Other ways to achieve similar results

Try to avoid using this suite of methods as it is neither efficient nor easy to maintain but it's a simple way to fix issues you might have.

You can usually do the same thing by using a service or by simplifying your controllers. We won't discuss this in detail but I thought I'd just mention it for completeness.

Lastly, keep in mind a really useful broadcast to listen to is '$destroy' again you can see the $ means it's a method or object created by the vendor codes. Anyways $destroy is broadcasted when a controller gets destroyed, you may want to listen to this to know when your controller is removed.

While looking at the same problem, I found an example

<style type="text/css">
#topright {
    position: absolute;
    right: 0;
    top: 0;
    display: block;
    height: 125px;
    width: 125px;
    background: url(TRbanner.gif) no-repeat;
    text-indent: -999em;
    text-decoration: none;
}
</style>

<a id="topright" href="#" title="TopRight">Top Right Link Text</a>

The trick here is to create a small, (I used GIMP) a PNG (or GIF) that has a transparent background, (and then just delete the opposite bottom corner.)

No need to embed! Just simply send the user to google and add the var in the search like this: (Remember, code might not work on this, so try in a browser if it doesn't.) Hope it works!

<textarea id="Blah"></textarea><button onclick="search()">Search</button>
<script>
function search() {
var Blah = document.getElementById("Blah").value;
location.replace("https://www.google.com/search?q=" + Blah + "");
}
</script>

    function search() {_x000D_
    var Blah = document.getElementById("Blah").value;_x000D_
    location.replace("https://www.google.com/search?q=" + Blah + "");_x000D_
    }

<textarea id="Blah"></textarea><button onclick="search()">Search</button>

Both are the same.The difference is how you use it. Convention is,

string is for variables

String is for calling other String class methods

Like:

string fName = "John";
string lName = "Smith";

string fullName = String.Concat(fName,lName);

if (String.IsNullOrEmpty(fName))
{
  Console.WriteLine("Enter first name");
}

local_settings.py, for django projects.

*~ for all projects.

Use:

CREATE PROCEDURE [dbo].[GetByName]
    @TableName NVARCHAR(100)
    AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;
    DECLARE @sSQL nvarchar(500);

    SELECT @sSQL = N'SELECT * FROM' + QUOTENAME(@TableName);

    EXEC sp_executesql @sSQL
END

Just use replace instead of replaceAll (which expects regex):

str = str.replace(",", ".");

or

str = str.replace(',', '.');

(replace takes as input either char or CharSequence, which is an interface implemented by String)

Also note that you should reassign the result

it's number_map[int(x)], you tried to actually call the map with one argument

Try:

int i = Convert.ToInt32(dt.Rows.Count);

I think it's the shortest, thus the simplest way.

Try this.

if(is_array($value) || is_object($value)){
    foreach($value as $item){
     //somecode
    }
}

Find if the given number is a power of 2.

#include <math.h>

int main(void)
{
    int n,logval,powval;
    printf("Enter a number to find whether it is s power of 2\n");
    scanf("%d",&n);
    logval=log(n)/log(2);
    powval=pow(2,logval);

    if(powval==n)
        printf("The number is a power of 2");
    else
        printf("The number is not a power of 2");

    getch();
    return 0;
}

This looks like a behavior difference in the handling of \s between grep 2.5 and newer versions (a bug in old grep?). I confirm your result with grep 2.5.4, but all four of your greps do work when using grep 2.6.3 (Ubuntu 10.10).

Note:

GNU grep 2.5.4
echo "foo bar" | grep "\s"
   (doesn't match)

whereas

GNU grep 2.6.3
echo "foo bar" | grep "\s"
foo bar

Probably less trouble (as \s is not documented):

Both GNU greps
echo "foo bar" | grep "[[:space:]]"
foo bar

My advice is to avoid using \s ... use [ \t]* or [[:space:]] or something like it instead.

in my cases, i found my password in glassfish-recources.xml under WEB-INF

Combining Dmitri & dcx's answers I made this:

function Confirm-WindowsServiceExists($name)
{   
    if (Get-Service $name -ErrorAction SilentlyContinue)
    {
        return $true
    }
    return $false
}

function Remove-WindowsServiceIfItExists($name)
{   
    $exists = Confirm-WindowsServiceExists $name
    if ($exists)
    {    
        sc.exe \\server delete $name
    }       
}

This is impossible to answer and has been brought up many many times before. Do a search, read those threads, then pick the framework you and your team have experience with.

You can do it with the options

Preflight is a web security feature implemented by the browser. For Chrome you can disable all web security by adding the --disable-web-security flag.

For example: "C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir="C:\newChromeSettingsWithoutSecurity" . You can first create a new shortcut of chrome, go to its properties and change the target as above. This should help!

From the context, the conflict was caused by the version of the package.
Let's take a look the manual about rpm:

--force
    Same as using --replacepkgs, --replacefiles, and --oldpackage.

--oldpackage
    Allow an upgrade to replace a newer package with an older one.

So, you can execute the command rpm -Uvh info-4.13a-2.rpm --force to solve your issue.

I've created a jQuery plugin that provides 4 additonal placements: topLeft, topRight, bottomLeft, bottomRight

You just include either the minified js or unminified js and have the matching css (minified vs unminified) in the same folder.

1. Run project in iPhone Simulator

2. Create in TextEdit file following file, call it MyOffice for example. Make extension as .gpx

   <?xml version="1.0"?> <gpx version="1.0" creator="MyName"> <wpt lat="53.936166" lon="27.565370"> <name>MyOffice</name> </wpt> </gpx>

3. Select in Xcode at the Simulate area Add GPX File to Project...

4. Add created file from menu to project.
5. Now you can see your location in Simulate area:

Enums are like Java Classes, they can have Constructors, Methods, etc. The only thing that you can't do with them is new EnumName(). The instances are predefined in your enum declaration.

There is the .update() method :)

update([other]) Update the dictionary with the key/value pairs from other, overwriting existing keys. Return None.

update() accepts either another dictionary object or an iterable of key/value pairs (as tuples or other iterables of length two). If keyword arguments are specified, the dictionary is then updated with those key/value pairs: d.update(red=1, blue=2).

Changed in version 2.4: Allowed the argument to be an iterable of key/value pairs and allowed keyword arguments.

This is a quicker fix in one-liner.

Hope this will help.

There are indeed a lot of string similarity measures out there:

• Levenshtein edit distance;
• Damerau-Levenshtein distance;
• Jaro-Winkler similarity;
• Longest Common Subsequence edit distance;
• Q-Gram (Ukkonen);
• n-Gram distance (Kondrak);
• Jaccard index;
• Sorensen-Dice coefficient;
• Cosine similarity;
• ...

You can find explanation and java implementation of these here: https://github.com/tdebatty/java-string-similarity

Sadly dependency:go-offline hasn't worked for me as it didn't cached everything, ie. POMs files and other implicitly mention dependencies.

The workaround has been to specify a local repository location, either within settings.xml file with <localRepository>...</localRepository> or by running mvn with -Dmaven.repo.local=... parameter. After initial project build, all necessary artifacts should be cached, and then you can reference repository location the same ways, while running Maven build in offline mode (mvn -o ...).

Here's how you can check the contents of the EntityValidationErrors in Visual Studio (without writing any extra code) i.e. during Debugging in the IDE.

The Problem?

You are right, the Visual Studio debugger's View Details Popup doesn't show the actual errors inside the EntityValidationErrors collection .

The Solution!

Just add the following expression in a Quick Watch window and click Reevaluate.

((System.Data.Entity.Validation.DbEntityValidationException)$exception).EntityValidationErrors

In my case, see how I am able to expand into the ValidationErrors List inside the EntityValidationErrors collection

EDIT: I just realized you want to filter details, which is an array of hashes. In that case you could do

details.reject { |item| item[:qty].empty? }

The inner data structure itself is not an Array, but a Hash. You can also use select here, but the block is given the key and value in this case:

irb(main):001:0> h = {:sku=>"507772-B21", :desc=>"HP 1TB 3G SATA 7.2K RPM LFF (3 .", :qty=>"", :qty2=>"1", :price=>"5,204.34 P"}
irb(main):002:0> h.select { |key, value| !value.empty? }
=> {:sku=>"507772-B21", :desc=>"HP 1TB 3G SATA 7.2K RPM LFF (3 .", 
    :qty2=>"1", :price=>"5,204.34 P"}

Or using reject, which is the inverse of select (excludes all items for which the given condition holds):

h.reject { |key, value| value.empty? }

Note that this is Ruby 1.9. If you have to maintain compatibility with 1.8, you could do:

Hash[h.reject { |key, value| value.empty? }]

The file opened by codecs.open is a file that takes unicode data, encodes it in iso-8859-1 and writes it to the file. However, what you try to write isn't unicode; you take unicode and encode it in iso-8859-1 yourself. That's what the unicode.encode method does, and the result of encoding a unicode string is a bytestring (a str type.)

You should either use normal open() and encode the unicode yourself, or (usually a better idea) use codecs.open() and not encode the data yourself.

You should apply the following styles:

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

This will give you the necessary effect, demo here.

jQuery doesn't have a convenient function for this. You need to combine contents(), which will give just child nodes but includes text nodes, with find(), which gives all descendant elements but no text nodes. Here's what I've come up with:

var getTextNodesIn = function(el) {
    return $(el).find(":not(iframe)").addBack().contents().filter(function() {
        return this.nodeType == 3;
    });
};

getTextNodesIn(el);

Note: If you're using jQuery 1.7 or earlier, the code above will not work. To fix this, replace addBack() with andSelf(). andSelf() is deprecated in favour of addBack() from 1.8 onwards.

This is somewhat inefficient compared to pure DOM methods and has to include an ugly workaround for jQuery's overloading of its contents() function (thanks to @rabidsnail in the comments for pointing that out), so here is non-jQuery solution using a simple recursive function. The includeWhitespaceNodes parameter controls whether or not whitespace text nodes are included in the output (in jQuery they are automatically filtered out).

Update: Fixed bug when includeWhitespaceNodes is falsy.

function getTextNodesIn(node, includeWhitespaceNodes) {
    var textNodes = [], nonWhitespaceMatcher = /\S/;

    function getTextNodes(node) {
        if (node.nodeType == 3) {
            if (includeWhitespaceNodes || nonWhitespaceMatcher.test(node.nodeValue)) {
                textNodes.push(node);
            }
        } else {
            for (var i = 0, len = node.childNodes.length; i < len; ++i) {
                getTextNodes(node.childNodes[i]);
            }
        }
    }

    getTextNodes(node);
    return textNodes;
}

getTextNodesIn(el);

changing the SVG file was not a fair solution for me so instead, I used relative CSS units.

vh, vw, % are very handy. I used a CSS like height: 2.4vh; to set a dynamic size to my SVG images.

met% python -c 'import this' | grep 'only one'
There should be one-- and preferably only one --obvious way to do it.

Use the ssh2 functions. Anything you'd do via an exec() call can be done directly using these functions, saving you a lot of connections and shell invocations.

I'm finding that it's kind of tricky to get pip3 (v9.0.1, as installed by Ubuntu 18.04's package manager) to actually install the thing I tell it to install. I'm posting this answer to save anyone's time who runs into this problem.

Putting this into a requirements.txt file failed:

git+git://github.com/myname/myrepo.git@my-branch#egg=eggname

By "failed" I mean that while it downloaded the code from Git, it ended up installing the original version of the code, as found on PyPi, instead of the code in the repo on that branch.

However, installing the commmit instead of the branch name works:

git+git://github.com/myname/myrepo.git@d27d07c9e862feb939e56d0df19d5733ea7b4f4d#egg=eggname

To find the version of the java in the classfiles I used:

javap -verbose <classname>

which announces the version at the start as

minor version: 0
major version: 49

which corresponds to Java 1.5

No problem. You're running your code under the debugger, and the debugger is telling you that it doesn't have debugging information for the system libraries.

If you really need that (usually for stack traces), you can download it from Microsoft's symbol servers, but for now you don't need to worry.

I wanted to achieve the same as asked in this question but accepted answer did not work for me in May, 2018 (maybe answer is too old or some other reason). I am using bootsrap 3.3.7 and ionic v1. You need to set line-height to do set height of specific row.

.blank_row {_x000D_
  line-height: 3px;_x000D_
}

  <tbody>_x000D_
    <tr class="header_row">_x000D_
      <td>Header Item</td>_x000D_
      <td>Header Item 2</td>_x000D_
      <td>Header Item 3</td>_x000D_

Here's a workaround.

Make a template subclass B of A. Do the template-argument-independent part of the construction in A's constructor. Do the template-argument-dependent part in B's constructor.

I used a modified version of this answer - based on my experiences adding it to VS 2010:

1. Select Tools >> External Tools in Visual Studio
2. Click Add
3. Title: I use Visual Studio Command &Prompt
   • &P Makes P a alt-shortcut key (when menu active)
   • I originally used C, but that conflicts with the existing shortcut for Customize
4. Command: C:\Windows\System32\cmd.exe
5. Arguments: \k "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\vsvars32.bat
   • /k keeps a secondary session active so the window doesn’t close on the .bat file
6. Initial Directory: I use $(ProjectDir) (from the dropdown)
7. Click OK.

Now you have command prompt access under the Tools Menu.

Another R package for aggregating multiple regression models into LaTeX tables is texreg.

Let's be honest, we should probably consider using a Python Software Foundation maintained library:

https://docs.python.org/3/library/configparser.html

Config example: (ini format, but JSON available)

[DEFAULT]
ServerAliveInterval = 45
Compression = yes
CompressionLevel = 9
ForwardX11 = yes

[bitbucket.org]
User = hg

[topsecret.server.com]
Port = 50022
ForwardX11 = no

Code example:

>>> import configparser
>>> config = configparser.ConfigParser()
>>> config.read('example.ini')
>>> config['DEFAULT']['Compression']
'yes'
>>> config['DEFAULT'].getboolean('MyCompression', fallback=True) # get_or_else

Making it globally-accessible:

import configpaser
class App:
 __conf = None

 @staticmethod
 def config():
  if App.__conf is None:  # Read only once, lazy.
   App.__conf = configparser.ConfigParser()
   App.__conf.read('example.ini')
  return App.__conf

if __name__ == '__main__':
 App.config()['DEFAULT']['MYSQL_PORT']
 # or, better:
 App.config().get(section='DEFAULT', option='MYSQL_PORT', fallback=3306)
 ....

Downsides:

• Uncontrolled global mutable state.

In short: Linear Regression gives continuous output. i.e. any value between a range of values. Logistic Regression gives discrete output. i.e. Yes/No, 0/1 kind of outputs.

Aside: attempt to amend Tomasz Nurkiewicz's answer was rejected:

This edit does not make the post even a little bit easier to read, easier to find, more accurate or more accessible. Changes are either completely superfluous or actively harm readability.

Correct and permanent link to the relevant section of documentation about integration testing.

To enable support for transactions, you must configure a PlatformTransactionManager bean in the ApplicationContext that is loaded via @ContextConfiguration semantics.

@Configuration
@PropertySource("application.properties")
public class Persistence {
    @Autowired
    Environment env;

    @Bean
    DataSource dataSource() {
        return new DriverManagerDataSource(
                env.getProperty("datasource.url"),
                env.getProperty("datasource.user"),
                env.getProperty("datasource.password")
        );
    }

    @Bean
    PlatformTransactionManager transactionManager() {
        return new DataSourceTransactionManager(dataSource());
    }
}

In addition, you must declare Spring’s @Transactional annotation either at the class or method level for your tests.

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {Persistence.class, SomeRepository.class})
@Transactional
public class SomeRepositoryTest { ... }

Annotating a test method with @Transactional causes the test to be run within a transaction that will, by default, be automatically rolled back after completion of the test. If a test class is annotated with @Transactional, each test method within that class hierarchy will be run within a transaction.

Use:

Question question = Question.Role;
int value = question.GetHashCode();

It will result in value == 2.

This is only true if the enum fits inside an int.

String tmpHtml = "<html>a whole bunch of html stuff</html>";
String htmlTextStr = Html.fromHtml(tmpHtml).toString();
