All proposed solutions didn't work for me but the closest one was from @Rishii.

I'm using AngularJS 1.4.4 and UI Bootstrap 0.13.3.

.directive('jsr310Compatible', ['dateFilter', 'dateParser', function(dateFilter, dateParser) {
  return {
    restrict: 'EAC',
    require: 'ngModel',
    priority: 1,
    link: function(scope, element, attrs, ngModel) {
      var dateFormat = 'yyyy-MM-dd';

      ngModel.$parsers.push(function(viewValue) {
        return dateFilter(viewValue, dateFormat);
      });

      ngModel.$validators.date = function (modelValue, viewValue) {
        var value = modelValue || viewValue;

        if (!attrs.ngRequired && !value) {
          return true;
        }

        if (angular.isNumber(value)) {
          value = new Date(value);
        }

        if (!value) {
          return true;
        }
        else if (angular.isDate(value) && !isNaN(value)) {
          return true;
        }
        else if (angular.isString(value)) {
          var date = dateParser.parse(value, dateFormat);
          return !isNaN(date);
        }
        else {
          return false;
        }
      };
    }
  };
}])

I think this will work even though this was forever ago.

SELECT employee_number, Row_Number()  
   OVER (PARTITION BY course_code ORDER BY course_completion_date DESC ) as rownum
FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
   AND rownum = 1

If you want to get the last Id if the date is the same then you can use this assuming your primary key is Id.

SELECT employee_number, Row_Number()  
   OVER (PARTITION BY course_code ORDER BY course_completion_date DESC, Id Desc) as rownum    FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
   AND rownum = 1

This two commands work for me in my project

composer require laravel/ui --dev

Then

php artisan ui:auth

I had the same error but I am using Perforce version control. Here's how I fixed it.

1. Closed Perforce P4V client
2. Restarted Visual Studio 2010 (might not be necessary)
3. Rebuilt the project, which succeeded
4. Felt exceptionally happy and disgusted at the same time

One of the difference is that merge is creating a new index, and join is keeping the left side index. It can have a big consequence on your later transformations if you wrongly assume that your index isn't changed with merge.

For example:

import pandas as pd

df1 = pd.DataFrame({'org_index': [101, 102, 103, 104],
                    'date': [201801, 201801, 201802, 201802],
                    'val': [1, 2, 3, 4]}, index=[101, 102, 103, 104])
df1

       date  org_index  val
101  201801        101    1
102  201801        102    2
103  201802        103    3
104  201802        104    4

-

df2 = pd.DataFrame({'date': [201801, 201802], 'dateval': ['A', 'B']}).set_index('date')
df2

       dateval
date          
201801       A
201802       B

-

df1.merge(df2, on='date')

     date  org_index  val dateval
0  201801        101    1       A
1  201801        102    2       A
2  201802        103    3       B
3  201802        104    4       B

-

df1.join(df2, on='date')
       date  org_index  val dateval
101  201801        101    1       A
102  201801        102    2       A
103  201802        103    3       B
104  201802        104    4       B

It depends on what function you want to run. If you need something done on server side, like querying a database or setting something in the session or anything that can not be done on client side, you need AJAX, else you can do it on client-side with JavaScript. Don't make the server work when you can do what you need to do on client side.

jQuery provides an easy way to do ajax : http://api.jquery.com/jQuery.ajax/

The simplest way to to check running processes:

ps auxwww | grep postgres

And look for a command that looks something like this (your version may not be 8.3):

/Library/PostgreSQL/8.3/bin/postgres -D /Library/PostgreSQL/8.3/data

To start the server, execute something like this:

/Library/PostgreSQL/8.3/bin/pg_ctl start -D /Library/PostgreSQL/8.3/data -l postgres.log

This is a big gray area in cookie SOP (Same Origin Policy).

Theoretically, you can specify port number in the domain and the cookie will not be shared. In practice, this doesn't work with several browsers and you will run into other issues. So this is only feasible if your sites are not for general public and you can control what browsers to use.

The better approach is to get 2 domain names for the same IP and not relying on port numbers for cookies.

If you have this code in your settings.json file, delete it:

{
    "python.jediEnabled": false
}

As for 2018 there is still not a simple answer to the question of how to convert a PDF document to an image in C#; many libraries use Ghostscript licensed under AGPL and in most cases an expensive commercial license is required for production use.

A good alternative might be using the popular 'pdftoppm' utility which has a GPL license; it can be used from C# as command line tool executed with System.Diagnostics.Process. Popular tools are well known in the Linux world, but a windows build is also available.

If you don't want to integrate pdftoppm by yourself, you can use my PdfRenderer popular wrapper (supports both classic .NET Framework and .NET Core) - it is not free, but pricing is very affordable.

I solved that problem by using a special setting for JsonSerializerSettings which is called TypeNameHandling.All

TypeNameHandling setting includes type information when serializing JSON and read type information so that the create types are created when deserializing JSON

Serialization:

var settings = new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All };
var text = JsonConvert.SerializeObject(configuration, settings);

Deserialization:

var settings = new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All };
var configuration = JsonConvert.DeserializeObject<YourClass>(json, settings);

The class YourClass might have any kind of base type fields and it will be serialized properly.

Store that objects into Array  and then iterate the Array
export class AppComponent {

 public obj: object =null;
 public myArr=[];

  constructor(){

    this.obj = {
      jon : {username: 'Jon', genrePref: 'rock'},
      lucy : {username: 'Lucy', genrePref: 'pop'},
      mike : {username: 'Mike', genrePref: 'rock'},
      luke : {username: 'Luke', genrePref: 'house'},
      james : {username: 'James', genrePref: 'house'},
      dave : {username: 'Dave', genrePref: 'bass'},
      sarah : {username: 'Sarah', genrePref: 'country'},
      natalie : {username: 'Natalie', genrePref: 'bass'}
  }
  }
  ngOnInit(){
    this.populateCode();
  }

  populateCode(){
    for( let i in this.obj) {   //Pay attention to the 'in'
    console.log(this.obj[i]);
    this.myArr.push(this.obj[i]);
  }
  }
 }



<div *ngFor="let item of myArr ">
    {{item.username}}
    {{item.genrePref}}
  </div>

Assuming you are using Windows forms, you could allow the user to select a row and in the delete key click event. It is recommended that you allow the user to select 1 row only and not a group of rows (myDataGridView.MultiSelect = false)

Private Sub pbtnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click

        If myDataGridView.SelectedRows.Count > 0 Then
            'you may want to add a confirmation message, and if the user confirms delete
            myDataGridView.Rows.Remove(myDataGridView.SelectedRows(0))
        Else
            MessageBox.Show("Select 1 row before you hit Delete")
        End If

    End Sub

Note that this will not delete the row form the database until you perform the delete in the database.

In principle, I use UserDefinedVariables (prepended with @) within Stored Procedures. This makes life easier, especially when I need these variables in two or more Stored Procedures. Just when I need a variable only within ONE Stored Procedure, than I use a System Variable (without prepended @).

@Xybo: I don't understand why using @variables in StoredProcedures should be risky. Could you please explain "scope" and "boundaries" a little bit easier (for me as a newbe)?

This might also help:

void ButtQuitClick(object sender, EventArgs e)
{
    QuitWin form = new QuitWin();
    form.Show();
}

Change ButtQuit to your button name and also change QuitWin to the name of the form that you made.

When the button is clicked it will open another window, you will need to make another form and a button on your main form for it to work.

So normally you would create a backing variable in the class and toggle it on click and tie a class binding to the variable. Something like:

@Component(
    selector:'foo',
    template:`<a (click)="onClick()"
                         [class.selected]="wasClicked">Link</a>
    `)
export class MyComponent {
    wasClicked = false;

    onClick() {
        this.wasClicked= !this.wasClicked;
    }
}

Heads up, you should be using the main thread for this action.

let center = UNUserNotificationCenter.current()
center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
        if granted {
            DispatchQueue.main.async(execute: {
                UIApplication.shared.registerForRemoteNotifications()
            })
        }
    }

A 404 return code actually means 'resource not found', and applies to any entity for which a request was made but not satisfied. So it works equally-well for pages, subsections of pages, and any item that exists on the page which has a specific request to be rendered.

So 404 is the right code to use in this scenario. Note that it doesn't apply to 'server not found', which is a different situation in which a request was issued but not answered at all, as opposed to answered but without the resource requested.

Suppose you have less data, I suggest to try 70%, 80% and 90% and test which is giving better result. In case of 90% there are chances that for 10% test you get poor accuracy.

In Notepad++ v7.8.9 you can use the Tab key to increase the indention level, and use Shift + Tab to decrease the indentation level.

Alternatively:

ALTER TABLE users
ADD COLUMN `status` INT(10) UNSIGNED NOT NULL AFTER `lastname`,
ADD COLUMN `log` VARCHAR(12) NOT NULL AFTER `lastname`,
ADD COLUMN `count` SMALLINT(6) NOT NULL AFTER `lastname`;

Will put them in the order you want while streamlining the AFTER statement.

None of the css trick worked for me (in my case the fb-like box was pulled right with "float:right"). However, what worked without any additional tricks is an IFRAME version of the button code. I.e.:

<iframe src="//www.facebook.com/plugins/like.php?href=..." 
        scrolling="no" frameborder="0" 
        style="border:none; overflow:hidden; width:71px; height:21px;" 
        allowTransparency="true">
</iframe>

(Note custom width in style, and no need to include additional javascript.)

My solution:

$defaultvalue = $options['data']->getMyField();
$builder->add('myField', 'number', array(
            'data' => !empty($defaultvalue) ? $options['data']->getMyField() : 0
        )) ;

This command line tool is the business! https://wkhtmltopdf.org/

It uses webkit rendering engine(used in safari and KDE), I tested it on some complex sites and it was by far better than any other tool.

Basically, no you have to make three delete statements in a transaction, children first and then parents. Setting up cascading deletes is a good idea if this is not a one-off thing and its existence won't conflict with any existing trigger setup.

Not perfect but close:

newcol<-sapply(rownames(t), function(rn){z[match(rn, rownames(z)), 5]})
cbind(data.frame(t), newcol)

Statements a == object2 and a.equals(object2) both will always return false because a is a string while object2 is an instance of MyClass

Making your own itoa is also easy, try this :

char* itoa(int i, char b[]){
    char const digit[] = "0123456789";
    char* p = b;
    if(i<0){
        *p++ = '-';
        i *= -1;
    }
    int shifter = i;
    do{ //Move to where representation ends
        ++p;
        shifter = shifter/10;
    }while(shifter);
    *p = '\0';
    do{ //Move back, inserting digits as u go
        *--p = digit[i%10];
        i = i/10;
    }while(i);
    return b;
}

or use the standard sprintf() function.

Your file .idea/workspace.xml is not under git version control. You have either not added it yet (check git status/Untracked files) or ignored it (using .gitignore or .git/info/exclude files)

You can verify it using following git command, that lists all ignored files:

git ls-files --others -i --exclude-standard

YOu can also try the following

   do {
        try {
            System.out.println("Enter first num: ");
            n1 = Integer.parseInt(input.next());

            System.out.println("Enter second num: ");
            n2 = Integer.parseInt(input.next());

            nQuotient = n1/n2;

            bError = false;
        } 
        catch (Exception e) {
            System.out.println("Error!");
            input.reset();
        }
    } while (bError);

in Javascript.

    var myObject = { "name" : "john" };
    // { "name" : "john" };
    myObject.gender = "male";
    // { "name" : "john", "gender":"male"};

Definitely late to the party; anyway, for those interested, picking up on Lan's mention of HTML5 canvas, you can use gRaphaël Charting which has a MIT License (instead of HighCharts dual license). It's not Bootstrap-specific either, so it's more of a general suggestion.

I have to admit that HighCharts demos seem very pretty, and I have to warn that gRaphaël is quite hard to understand before becoming proficient with it. Anyway you can easily add nice features to your gRaphaël charts (say, tooltips or zooming effects), so it may be worth the effort.

To get the specific tag code try to create a new branch add get the tag code in it. I have done it by command : $git checkout -b newBranchName tagName

Use this commad when first connect to psql

The problem is that you can't use a list as the key in a dict, since dict keys need to be immutable. Use a tuple instead.

This is a list:

[x, y]

This is a tuple:

(x, y)

Note that in most cases, the ( and ) are optional, since , is what actually defines a tuple (as long as it's not surrounded by [] or {}, or used as a function argument).

You might find the section on tuples in the Python tutorial useful:

Though tuples may seem similar to lists, they are often used in different situations and for different purposes. Tuples are immutable, and usually contain an heterogeneous sequence of elements that are accessed via unpacking (see later in this section) or indexing (or even by attribute in the case of namedtuples). Lists are mutable, and their elements are usually homogeneous and are accessed by iterating over the list.

And in the section on dictionaries:

Unlike sequences, which are indexed by a range of numbers, dictionaries are indexed by keys, which can be any immutable type; strings and numbers can always be keys. Tuples can be used as keys if they contain only strings, numbers, or tuples; if a tuple contains any mutable object either directly or indirectly, it cannot be used as a key. You can’t use lists as keys, since lists can be modified in place using index assignments, slice assignments, or methods like append() and extend().

In case you're wondering what the error message means, it's complaining because there's no built-in hash function for lists (by design), and dictionaries are implemented as hash tables.

As an alternative, StringUtils from Apache Commons can be used.

 byte[] bytes = {(byte) 1};
 String convertedString = StringUtils.newStringUtf8(bytes);

or

 String myString = "example";
 byte[] convertedBytes = StringUtils.getBytesUtf8(myString);

If you have non-standard charset, you can use getBytesUnchecked() or newString() accordingly.

The "responsible" answer would be for me to suggest building a ViewModel for the dialog and use two-way databinding on the TextBox so that the ViewModel had some "ResponseText" property or what not. This is easy enough to do but probably overkill.

The pragmatic answer would be to just give your text box an x:Name so that it becomes a member and expose the text as a property in your code behind class like so:

<!-- Incredibly simplified XAML -->
<Window x:Class="MyDialog">
   <StackPanel>
       <TextBlock Text="Enter some text" />
       <TextBox x:Name="ResponseTextBox" />
       <Button Content="OK" Click="OKButton_Click" />
   </StackPanel>
</Window>

Then in your code behind...

partial class MyDialog : Window {

    public MyDialog() {
        InitializeComponent();
    }

    public string ResponseText {
        get { return ResponseTextBox.Text; }
        set { ResponseTextBox.Text = value; }
    }

    private void OKButton_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        DialogResult = true;
    }
}

Then to use it...

var dialog = new MyDialog();
if (dialog.ShowDialog() == true) {
    MessageBox.Show("You said: " + dialog.ResponseText);
}

This will work in all JavaScript implementations:

var keys = [];

for (var key in driversCounter) {
    if (driversCounter.hasOwnProperty(key)) {
        keys.push(key);
    }
}

Like others mentioned before you may use Object.keys, but it may not work in older engines. So you can use the following monkey patch:

if (!Object.keys) {
    Object.keys = function (object) {
        var keys = [];

        for (var key in object) {
            if (object.hasOwnProperty(key)) {
                keys.push(key);
            }
        }
    }
}

If you want to find the rows that have any of the values in a vector, one option is to loop the vector (lapply(v1,..)), create a logical index of (TRUE/FALSE) with (==). Use Reduce and OR (|) to reduce the list to a single logical matrix by checking the corresponding elements. Sum the rows (rowSums), double negate (!!) to get the rows with any matches.

indx1 <- !!rowSums(Reduce(`|`, lapply(v1, `==`, df)), na.rm=TRUE)

Or vectorise and get the row indices with which with arr.ind=TRUE

indx2 <- unique(which(Vectorize(function(x) x %in% v1)(df),
                                     arr.ind=TRUE)[,1])

Benchmarks

I didn't use @kristang's solution as it is giving me errors. Based on a 1000x500 matrix, @konvas's solution is the most efficient (so far). But, this may vary if the number of rows are increased

val <- paste0('M0', 1:1000)
set.seed(24)
df1 <- as.data.frame(matrix(sample(c(val, NA), 1000*500, 
  replace=TRUE), ncol=500), stringsAsFactors=FALSE) 
set.seed(356)
v1 <- sample(val, 200, replace=FALSE)

 konvas <- function() {apply(df1, 1, function(r) any(r %in% v1))}
 akrun1 <- function() {!!rowSums(Reduce(`|`, lapply(v1, `==`, df1)),
               na.rm=TRUE)}
 akrun2 <- function() {unique(which(Vectorize(function(x) x %in% 
              v1)(df1),arr.ind=TRUE)[,1])}


 library(microbenchmark)
 microbenchmark(konvas(), akrun1(), akrun2(), unit='relative', times=20L)
 #Unit: relative
 #   expr       min         lq       mean     median         uq      max   neval

I noticed there is no no-custom class, n-length, no-cast, type-safe answers yet to returning multiple values.

Here is my go:

import java.util.Objects;

public final class NTuple<V, T extends  NTuple<?, ?>> {
    private final V value;
    private final T next;

    private NTuple(V value, T next) {
        this.value = value;
        this.next = next;
    }

    public static <V> NTuple<V, ?> of(V value) {
        return new NTuple<>(value, null);
    }

    public static <V,  T extends  NTuple<?, ?>> NTuple<V, T> of(V value, T next) {
        return new NTuple<>(value, next);
    }

    public V value() {

        return next;
    }

    public static <V> V unpack0(NTuple<V, ?> tuple) {
        return Objects.requireNonNull(tuple, "0").value();
    }

    public static <V, T extends NTuple<V, ?>> V unpack1(NTuple<?, T> tuple) {
        NTuple<?, T> tuple0 = Objects.requireNonNull(tuple, "0");
        NTuple<V, ?> tuple1 = Objects.requireNonNull(tuple0.next(), "1");
        return tuple1.value();
    }

    public static <V, T extends NTuple<?, NTuple<V, ?>>> V unpack2(NTuple<?, T> tuple) {
        NTuple<?, T> tuple0 = Objects.requireNonNull(tuple, "0");
        NTuple<?, NTuple<V, ?>> tuple1 = Objects.requireNonNull(tuple0.next(), "1");
        NTuple<V, ?> tuple2 = Objects.requireNonNull(tuple1.next(), "2");
        return tuple2.value();
    }
}

Sample use:

public static void main(String[] args) {
    // pre-java 10 without lombok - use lombok's var or java 10's var if you can
    NTuple<String, NTuple<Integer, NTuple<Integer, ?>>> multiple = wordCount("hello world");
    String original = NTuple.unpack0(multiple);
    Integer wordCount = NTuple.unpack1(multiple);
    Integer characterCount  = NTuple.unpack2(multiple);

    System.out.println(original + ": " + wordCount + " words " + characterCount + " chars");
}

private static NTuple<String, NTuple<Integer, NTuple<Integer, ?>>> wordCount(String s) {
    int nWords = s.split(" ").length;
    int nChars = s.length();
    return NTuple.of(s, NTuple.of(nWords, NTuple.of(nChars)));
}

Pros:

• no-custom container class - no need to write a class just for a return type
• n-length - can handle any number of return values
• no-cast - no need to cast from Object
• type-safe - the types are checked via Java's generics

Cons:

• inefficient for large numbers of return values
  • according to my experience with python's multiple return values, this should not happen in practice
• heavy type declarations
  • can be alleviated by lombok/Java 10 var

While many are taking the approach to stop/disable IIS, it may be helpful to know that you can simply modify the XAMPP port, which has been answered here. This is the route I had to take as I need both running.

To solve this, I ensured all my projects used the same version by running the following command and checking the results:

update-package Newtonsoft.Json -reinstall

And, lastly I removed the following from my web.config:

  <dependentAssembly>
    <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
  </dependentAssembly>

If you want to ensure all your Newtonsoft.Json packages are the same version, you can specify the version like so:

update-package Newtonsoft.Json -version 6.0.0 -reinstall

Heroes of Might and Magic V used modified Silent Storm engine. I think you can find many good engines listed in wikipedia: Lua-scriptable game engines

Swift version

Updated for Swift 3

This example will show two methods to programmatically add the following constraints the same as if doing it in the Interface Builder:

Width and Height

Center in Container

Boilerplate code

override func viewDidLoad() {
    super.viewDidLoad()

    // set up the view
    let myView = UIView()
    myView.backgroundColor = UIColor.blue
    myView.translatesAutoresizingMaskIntoConstraints = false
    view.addSubview(myView)

    // Add constraints code here (choose one of the methods below)
    // ...
}

Method 1: Anchor Style

// width and height
myView.widthAnchor.constraint(equalToConstant: 200).isActive = true
myView.heightAnchor.constraint(equalToConstant: 100).isActive = true

// center in container
myView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
myView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true

Method 2: NSLayoutConstraint Style

// width and height
NSLayoutConstraint(item: myView, attribute: NSLayoutAttribute.width, relatedBy: NSLayoutRelation.equal, toItem: nil, attribute: NSLayoutAttribute.notAnAttribute, multiplier: 1, constant: 200).isActive = true
NSLayoutConstraint(item: myView, attribute: NSLayoutAttribute.height, relatedBy: NSLayoutRelation.equal, toItem: nil, attribute: NSLayoutAttribute.notAnAttribute, multiplier: 1, constant: 100).isActive = true

// center in container
NSLayoutConstraint(item: myView, attribute: NSLayoutAttribute.centerX, relatedBy: NSLayoutRelation.equal, toItem: view, attribute: NSLayoutAttribute.centerX, multiplier: 1, constant: 0).isActive = true
NSLayoutConstraint(item: myView, attribute: NSLayoutAttribute.centerY, relatedBy: NSLayoutRelation.equal, toItem: view, attribute: NSLayoutAttribute.centerY, multiplier: 1, constant: 0).isActive = true

Notes

• Anchor style is the preferred method over NSLayoutConstraint Style, however it is only available from iOS 9, so if you are supporting iOS 8 then you should still use NSLayoutConstraint Style.
• See also the Programmatically Creating Constraints documentation.
• See this answer for a similar example of adding a pinning constraint.

As you know angular.module( declared under angular.js file.So before accessing angular.module, you must have make it available by using <script src="lib/angular/angular.js"></script>(In your case) after then you can call angular.module. It will work.

like

<html lang="en">
<head>
  <meta charset="utf-8">
  <title>My AngularJS App</title>
  <link rel="stylesheet" href="css/app.css"/>
<!-- In production use:
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
  -->
  <script src="lib/angular/angular.js"></script>
  <script src="lib/angular/angular-route.js"></script>
  <script src="js/app.js"></script>
  <script src="js/services.js"></script>
  <script src="js/controllers.js"></script>
  <script src="js/filters.js"></script>
  <script src="js/directives.js"></script>

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

        app.directive('myDirective',function(){

            return function(scope, element,attrs) {
                element.bind('click',function() {alert('click')});
            };

        });
    </script>
</head>
<body ng-app="myApp">
    <div >
        <button my-directive>Click Me!</button>
    </div>
    <h1>{{2+3}}</h1>

</body>
</html>

Wonderful answer! I needed to fill in the empty cells in a column where there were titles in cells that applied to the empty cells below until the next title cell.

I used your code above to develop the code that is below my example sheet here. I applied this code as a macro ctl/shft/D to rapidly run down the column copying the titles.

--- Example Spreadsheet ------------ Title1 is copied to rows 2 and 3; Title2 is copied to cells below it in rows 5 and 6. After the second run of the Macro the active cell is the Title3 cell.

 ' **row** **Column1**        **Column2**
 '    1     Title1         Data 1 for title 1
 '    2                    Data 2 for title 1
 '    3                    Data 3 for title 1
 '    4     Title2         Data 1 for title 2
 '    5                    Data 2 for title 2
 '    6                    Data 3 for title 2
 '    7   Title 3          Data 1 for title 3

----- CopyDown code ----------

Sub CopyDown()
Dim Lastrow As String, FirstRow As String, strtCell As Range
'
' CopyDown Macro
' Copies the current cell to any empty cells below it.   
'
' Keyboard Shortcut: Ctrl+Shift+D
'
    Set strtCell = ActiveCell
    FirstRow = strtCell.Address
' Lastrow is address of the *list* of empty cells
    Lastrow = Range(Selection, Selection.End(xlDown).Offset(-1, 0)).Address
'   MsgBox Lastrow
    Range(Lastrow).Formula = strtCell.Formula

    Range(Lastrow).End(xlDown).Select
 End Sub

Your keys may already be in PEM format, but just named with .crt or .key.

If the file's content begins with -----BEGIN and you can read it in a text editor:

The file uses base64, which is readable in ASCII, not binary format. The certificate is already in PEM format. Just change the extension to .pem.

If the file is in binary:

For the server.crt, you would use

openssl x509 -inform DER -outform PEM -in server.crt -out server.crt.pem

For server.key, use openssl rsa in place of openssl x509.

The server.key is likely your private key, and the .crt file is the returned, signed, x509 certificate.

If this is for a Web server and you cannot specify loading a separate private and public key:

You may need to concatenate the two files. For this use:

cat server.crt server.key > server.includesprivatekey.pem

I would recommend naming files with "includesprivatekey" to help you manage the permissions you keep with this file.

The click() binding you're using is called a "direct" binding which will only attach the handler to elements that already exist. It won't get bound to elements created in the future. To do that, you'll have to create a "delegated" binding by using on().

Delegated events have the advantage that they can process events from descendant elements that are added to the document at a later time.

^Source

Here's what you're looking for:

var counter = 0;_x000D_
_x000D_
$("button").click(function() {_x000D_
    $("h2").append("<p class='test'>click me " + (++counter) + "</p>")_x000D_
});_x000D_
_x000D_
// With on():_x000D_
_x000D_
$("h2").on("click", "p.test", function(){_x000D_
    alert($(this).text());_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>_x000D_
<h2></h2>_x000D_
<button>generate new element</button>

The above works for those using jQuery version 1.7+. If you're using an older version, refer to the previous answer below.

Previous Answer:

Try using live():

$("button").click(function(){
    $("h2").html("<p class='test'>click me</p>")
});   


$(".test").live('click', function(){
    alert('you clicked me!');
});

Worked for me. Tried it with jsFiddle.

Or there's a new-fangled way of doing it with delegate():

$("h2").delegate("p", "click", function(){
    alert('you clicked me again!');
});

An updated jsFiddle.

Use

cut -b COLUMN_N_BEGINS-COLUMN_N_UNTIL INPUT.TXT > OUTPUT.TXT

-f doesn't work if you have "tabs" in the text file.

In iOS 6 you can set the tint color of UIPageControl:

There are 2 new properties:

• pageIndicatorTintColor
• currentPageIndicatorTintColor

You can also use the appearance API to change the tint color of all page indicators.

If you are targeting iOS 5 make sure it doesn't crash:

if ([pageControl respondsToSelector:@selector(setPageIndicatorTintColor:)]) {
    pageControl.pageIndicatorTintColor = [UIColor whiteColor];
}

You can also setup multiple domain with nginx, forwarding to multiple node.js processes.

For example to achieve these:

• domain1.com -> to Node.js process running locally http://127.0.0.1:4000
• domain2.com -> to Node.js process running locally http://127.0.0.1:5000

These ports (4000 and 5000) should be used to listen the app requests in your app code.

/etc/nginx/sites-enabled/domain1

server {
    listen 80;
    listen [::]:80;
    server_name domain1.com;
    access_log /var/log/nginx/domain1.access.log;
    location / {
        proxy_pass    http://127.0.0.1:4000/;
    }
}

In /etc/nginx/sites-enabled/domain2

server {
    listen 80;
    listen [::]:80;
    server_name domain2.com;
    access_log /var/log/nginx/domain2.access.log;
    location / {
        proxy_pass    http://127.0.0.1:5000/;
    }
}

Inline SVG can be used in IE 10 and 11 and Edge 12.

I've created a project called gray which includes a polyfill for these browsers. The polyfill switches out <img> tags with inline SVG: https://github.com/karlhorky/gray

To implement, the short version is to download the jQuery plugin at the GitHub link above and add after jQuery at the end of your body:

<script src="/js/jquery.gray.min.js"></script>

Then every image with the class grayscale will appear as gray.

<img src="/img/color.jpg" class="grayscale">

You can see a demo too if you like.

It depends on the tools you can use. I doubt there is a JavaScript too that could do it directly within the browser. It also depends if it's a one-off (always the same key) or whether you need to script it.

Command-line / OpenSSL

If you want to use something like OpenSSL on a unix command line, you can do something as follows. I'm assuming you public.key file contains something like this:

-----BEGIN PUBLIC KEY-----
MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAmBAjFv+29CaiQqYZIw4P
J0q5Qz2gS7kbGleS3ai8Xbhu5n8PLomldxbRz0RpdCuxqd1yvaicqpDKe/TT09sR
mL1h8Sx3Qa3EQmqI0TcEEqk27Ak0DTFxuVrq7c5hHB5fbJ4o7iEq5MYfdSl4pZax
UxdNv4jRElymdap8/iOo3SU1RsaK6y7kox1/tm2cfWZZhMlRFYJnpoXpyNYrp+Yo
CNKxmZJnMsS698kaFjDlyznLlihwMroY0mQvdD7dCeBoVlfPUGPAlamwWyqtIU+9
5xVkSp3kxcNcNb/mePSKQIPafQ1sAmBKPwycA/1I5nLzDVuQa95ZWMn0JkphtFIh
HQIDAQAB
-----END PUBLIC KEY-----

Then, the commands would be:

PUBKEY=`grep -v -- ----- public.key | tr -d '\n'`

Then, you can look into the ASN.1 structure:

echo $PUBKEY | base64 -d | openssl asn1parse -inform DER -i

This should give you something like this:

    0:d=0  hl=4 l= 290 cons: SEQUENCE          
    4:d=1  hl=2 l=  13 cons:  SEQUENCE          
    6:d=2  hl=2 l=   9 prim:   OBJECT            :rsaEncryption
   17:d=2  hl=2 l=   0 prim:   NULL              
   19:d=1  hl=4 l= 271 prim:  BIT STRING 

The modulus and public exponent are in the last BIT STRING, offset 19, so use -strparse:

 echo $PUBKEY | base64 -d | openssl asn1parse -inform DER -i -strparse 19

This will give you the modulus and the public exponent, in hexadecimal (the two INTEGERs):

    0:d=0  hl=4 l= 266 cons: SEQUENCE          
    4:d=1  hl=4 l= 257 prim:  INTEGER           :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
  265:d=1  hl=2 l=   3 prim:  INTEGER           :010001

That's probably fine if it's always the same key, but this is probably not very convenient to put in a script.

Alternatively (and this might be easier to put into a script),

openssl rsa -pubin -inform PEM -text -noout < public.key

will return this:

Modulus (2048 bit):

Java

It depends on the input format. If it's an X.509 certificate in a keystore, use (RSAPublicKey)cert.getPublicKey(): this object has two getters for the modulus and the exponent.

If it's in the format as above, you might want to use BouncyCastle and its PEMReader to read it. I haven't tried the following code, but this would look more or less like this:

PEMReader pemReader = new PEMReader(new FileReader("file.pem"));
Object obj = pemReader.readObject();
pemReader.close();
if (obj instanceof X509Certificate) {
   // Just in case your file contains in fact an X.509 certificate,
   // useless otherwise.
   obj = ((X509Certificate)obj).getPublicKey();
}
if (obj instanceof RSAPublicKey) {
   // ... use the getters to get the BigIntegers.
}

(You can use BouncyCastle similarly in C# too.)

There is also another difference:

null instanceof X is false no matter what X is

null.getClass().isAssignableFrom(X) will throw a NullPointerException

To get the day from any given date, just pass the date into a new Date object:

let date = new Date("01/05/2020");
let day = date.toLocaleString('en-us', {weekday: 'long'});
console.log(day);
// expected result = tuesday

To read more, go to mdn-date.prototype.toLocaleString()(https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleString)

You can do union or simple list comprehension

[A.add(_) for _ in B]

A would have all the elements of B

It may not be the elegant way but you can iterate all classes in the assembly and invoke Type.IsSubclassOf(AbstractDataExport) for each one.

If the project is check out to different PC through team foundation server with different location of same library file, there will be no yellow icon mark in Reference but when change to Release build and build the project, it will give an error. Just like what @C.Evenhuis said, it will use back old one in previous build (eg: Debug build) so I didn't notice the mistake.

Now I know it is a bad habit to put library files in different location on different PC.

Just need to delete the reference and re-add the same reference from correct location.

I found Serge's answer to be very promising, but I also encountered performance issues with it as-written. However, when I restructured it to use temporary tables and not include double CTE tables, the performance went from 1 minute 40 seconds to sub-second for 1000 combined records. Here it is for anyone who needs to do this without FOR XML on older versions of SQL Server:

DECLARE @STRUCTURED_VALUES TABLE (
     ID                 INT
    ,VALUE              VARCHAR(MAX) NULL
    ,VALUENUMBER        BIGINT
    ,VALUECOUNT         INT
);

INSERT INTO @STRUCTURED_VALUES
SELECT   ID
        ,VALUE
        ,ROW_NUMBER() OVER (PARTITION BY ID ORDER BY VALUE) AS VALUENUMBER
        ,COUNT(*) OVER (PARTITION BY ID)    AS VALUECOUNT
FROM    RAW_VALUES_TABLE;

WITH CTE AS (
    SELECT   SV.ID
            ,SV.VALUE
            ,SV.VALUENUMBER
            ,SV.VALUECOUNT
    FROM    @STRUCTURED_VALUES SV
    WHERE   VALUENUMBER = 1

    UNION ALL

    SELECT   SV.ID
            ,CTE.VALUE + ' ' + SV.VALUE AS VALUE
            ,SV.VALUENUMBER
            ,SV.VALUECOUNT
    FROM    @STRUCTURED_VALUES SV
    JOIN    CTE 
        ON  SV.ID = CTE.ID
        AND SV.VALUENUMBER = CTE.VALUENUMBER + 1

)
SELECT   ID
        ,VALUE
FROM    CTE
WHERE   VALUENUMBER = VALUECOUNT
ORDER BY ID
;

In Maven: The Definitive Guide, I wrote about the differences between Maven and Ant in the introduction the section title is "The Differences Between Ant and Maven". Here's an answer that is a combination of the info in that introduction with some additional notes.

A Simple Comparison

I'm only showing you this to illustrate the idea that, at the most basic level, Maven has built-in conventions. Here's a simple Ant build file:

<project name="my-project" default="dist" basedir=".">
    <description>
        simple example build file
    </description>   
    <!-- set global properties for this build -->   
    <property name="src" location="src/main/java"/>
    <property name="build" location="target/classes"/>
    <property name="dist"  location="target"/>

    <target name="init">
      <!-- Create the time stamp -->
      <tstamp/>
      <!-- Create the build directory structure used by compile -->
      <mkdir dir="${build}"/>   
    </target>

    <target name="compile" depends="init"
        description="compile the source " >
      <!-- Compile the java code from ${src} into ${build} -->
      <javac srcdir="${src}" destdir="${build}"/>  
    </target>

    <target name="dist" depends="compile"
        description="generate the distribution" >
      <!-- Create the distribution directory -->
      <mkdir dir="${dist}/lib"/>

      <!-- Put everything in ${build} into the MyProject-${DSTAMP}.jar file
-->
      <jar jarfile="${dist}/lib/MyProject-${DSTAMP}.jar" basedir="${build}"/>
   </target>

   <target name="clean"
        description="clean up" >
     <!-- Delete the ${build} and ${dist} directory trees -->
     <delete dir="${build}"/>
     <delete dir="${dist}"/>
   </target>
 </project>

In this simple Ant example, you can see how you have to tell Ant exactly what to do. There is a compile goal which includes the javac task that compiles the source in the src/main/java directory to the target/classes directory. You have to tell Ant exactly where your source is, where you want the resulting bytecode to be stored, and how to package this all into a JAR file. While there are some recent developments that help make Ant less procedural, a developer's experience with Ant is in coding a procedural language written in XML.

Contrast the previous Ant example with a Maven example. In Maven, to create a JAR file from some Java source, all you need to do is create a simple pom.xml, place your source code in ${basedir}/src/main/java and then run mvn install from the command line. The example Maven pom.xml that achieves the same results.

</project>

That's all you need in your pom.xml. Running mvn install from the command line will process resources, compile source, execute unit tests, create a JAR, and install the JAR in a local repository for reuse in other projects. Without modification, you can run mvn site and then find an index.html file in target/site that contains links to JavaDoc and a few reports about your source code.

Admittedly, this is the simplest possible example project. A project which only contains source code and which produces a JAR. A project which follows Maven conventions and doesn't require any dependencies or customization. If we wanted to start customizing the behavior, our pom.xml is going to grow in size, and in the largest of projects you can see collections of very complex Maven POMs which contain a great deal of plugin customization and dependency declarations. But, even when your project's POM files become more substantial, they hold an entirely different kind of information from the build file of a similarly sized project using Ant. Maven POMs contain declarations: "This is a JAR project", and "The source code is in src/main/java". Ant build files contain explicit instructions: "This is project", "The source is in src/main/java", "Run javac against this directory", "Put the results in target/classses", "Create a JAR from the ....", etc. Where Ant had to be explicit about the process, there was something "built-in" to Maven that just knew where the source code was and how it should be processed.

High-level Comparison

The differences between Ant and Maven in this example? Ant...

• doesn't have formal conventions like a common project directory structure, you have to tell Ant exactly where to find the source and where to put the output. Informal conventions have emerged over time, but they haven't been codified into the product.
• is procedural, you have to tell Ant exactly what to do and when to do it. You had to tell it to compile, then copy, then compress.
• doesn't have a lifecycle, you had to define goals and goal dependencies. You had to attach a sequence of tasks to each goal manually.

Where Maven...

• has conventions, it already knew where your source code was because you followed the convention. It put the bytecode in target/classes, and it produced a JAR file in target.
• is declarative. All you had to do was create a pom.xml file and put your source in the default directory. Maven took care of the rest.
• has a lifecycle, which you invoked when you executed mvn install. This command told Maven to execute a series of sequence steps until it reached the lifecycle. As a side-effect of this journey through the lifecycle, Maven executed a number of default plugin goals which did things like compile and create a JAR.

What About Ivy?

Right, so someone like Steve Loughran is going to read that comparison and call foul. He's going to talk about how the answer completely ignores something called Ivy and the fact that Ant can reuse build logic in the more recent releases of Ant. This is true. If you have a bunch of smart people using Ant + antlibs + Ivy, you'll end up with a well designed build that works. Even though, I'm very much convinced that Maven makes sense, I'd happily use Ant + Ivy with a project team that had a very sharp build engineer. That being said, I do think you'll end up missing out on a number of valuable plugins such as the Jetty plugin and that you'll end up doing a whole bunch of work that you didn't need to do over time.

More Important than Maven vs. Ant

1. Is that you use a Repository Manager to keep track of software artifacts. I'd suggest downloading Nexus. You can use Nexus to proxy remote repositories and to provide a place for your team to deploy internal artifacts.
2. You have appropriate modularization of software components. One big monolithic component rarely scales over time. As your project develops, you'll want to have the concept of modules and sub-modules. Maven lends itself to this approach very well.
3. You adopt some conventions for your build. Even if you use Ant, you should strive to adopt some form of convention that is consistent with other projects. When a project uses Maven, it means that anyone familiar with Maven can pick up the build and start running with it without having to fiddle with configuration just to figure out how to get the thing to compile.

You can do it with:

dotnet ef migrations remove

Warning

Take care not to remove any migrations which are already applied to production databases. Not doing so will prevent you from being able to revert it, and may break the assumptions made by subsequent migrations.

I tried many thing to get DELETE method work (I was getting 405 method not allowed web api) , and finally I added [Route("api/scan/{id}")] to my controller and was work fine. hope this post help some one.

     // DELETE api/Scan/5
    [Route("api/scan/{id}")]
    [ResponseType(typeof(Scan))]
    public IHttpActionResult DeleteScan(int id)
    {
        Scan scan = db.Scans.Find(id);
        if (scan == null)
        {
            return NotFound();
        }

        db.Scans.Remove(scan);
        db.SaveChanges();

        return Ok(scan);
    }

Update 2016:

Google Chrome released the storage API: http://developer.chrome.com/extensions/storage.html

It is pretty easy to use like the other Chrome APIs and you can use it from any page context within Chrome.

    // Save it using the Chrome extension storage API.
    chrome.storage.sync.set({'foo': 'hello', 'bar': 'hi'}, function() {
      console.log('Settings saved');
    });

    // Read it using the storage API
    chrome.storage.sync.get(['foo', 'bar'], function(items) {
      message('Settings retrieved', items);
    });

To use it, make sure you define it in the manifest:

    "permissions": [
      "storage"
    ],

There are methods to "remove", "clear", "getBytesInUse", and an event listener to listen for changed storage "onChanged"

Using native localStorage (old reply from 2011)

Content scripts run in the context of webpages, not extension pages. Therefore, if you're accessing localStorage from your contentscript, it will be the storage from that webpage, not the extension page storage.

Now, to let your content script to read your extension storage (where you set them from your options page), you need to use extension message passing.

The first thing you do is tell your content script to send a request to your extension to fetch some data, and that data can be your extension localStorage:

contentscript.js

chrome.runtime.sendMessage({method: "getStatus"}, function(response) {
  console.log(response.status);
});

background.js

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
    if (request.method == "getStatus")
      sendResponse({status: localStorage['status']});
    else
      sendResponse({}); // snub them.
});

You can do an API around that to get generic localStorage data to your content script, or perhaps, get the whole localStorage array.

I hope that helped solve your problem.

To be fancy and generic ...

contentscript.js

chrome.runtime.sendMessage({method: "getLocalStorage", key: "status"}, function(response) {
  console.log(response.data);
});

background.js

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
    if (request.method == "getLocalStorage")
      sendResponse({data: localStorage[request.key]});
    else
      sendResponse({}); // snub them.
});

What are disadvantages of the following solution? Seems to be faster and shorter.

var options = {
    set0: ['Option 1','Option 2'],
    set1: ['First Option','Second Option','Third Option']
};

var list = "<li>" + options.set0.join("</li><li>") + "</li>";
document.getElementById("list").innerHTML = list;

http://api.football-data.org/index is free and useful. The API is in active development, stable and recently the first versioned release called alpha was put online. Check the blog section to follow updates and changes.

Other possible solution:

tv.setText(Integer.toString(a1));  // where a1 - int value

You need to get id from:

youtube.com/watch?v=VIDEO_ID

And put this in:

i.ytimg.com/vi/VIDEO_ID/maxresdefault.jpg

I hope that I helped :D

Note that this may also work:

SELECT * FROM table WHERE s=ANY(array)

SQL doesn't typically allow you to reference column aliases in WHERE, GROUP BY or HAVING clauses. MySQL does support referencing column aliases in the GROUP BY and HAVING, but I stress that it will cause problems when porting such queries to other databases.

When in doubt, use the actual column name:

SELECT t.lat AS latitude 
  FROM poi_table t
 WHERE t.lat < 500

I added a table alias to make it easier to see what is an actual column vs alias.

Update

A computed column, like the one you see here:

SELECT *, 
       ( 6371*1000 * acos( cos( radians(42.3936868308) ) * cos( radians( lat ) ) * cos( radians( lon ) - radians(-72.5277256966) ) + sin( radians(42.3936868308) ) * sin( radians( lat ) ) ) ) AS distance
  FROM poi_table 
 WHERE distance < 500;

...doesn't change that you can not reference a column alias in the WHERE clause. For that query to work, you'd have to use:

SELECT *, 
       ( 6371*1000 * acos( cos( radians(42.3936868308) ) * cos( radians( lat ) ) * cos( radians( lon ) - radians(-72.5277256966) ) + sin( radians(42.3936868308) ) * sin( radians( lat ) ) ) ) AS distance
  FROM poi_table
 WHERE ( 6371*1000 * acos( cos( radians(42.3936868308) ) * cos( radians( lat ) ) * cos( radians( lon ) - radians(-72.5277256966) ) + sin( radians(42.3936868308) ) * sin( radians( lat ) ) ) ) < 500;

Be aware that using a function on a column (IE: RADIANS(lat)) will render an index useless, if one exists on the column.

Try this for javascript:

const strippedString = htmlString.replace(/(<([^>]+)>)/gi, "");
console.log(strippedString);

Well using find is the best option here

just simply use like this

$(".class").click(function(){
        $("this").find('.subclass').css("visibility","visible");
})

and if there are many classes with the same name class its always better to give the class name of parent class like this

$(".parent .class").click(function(){
            $("this").find('.subclass').css("visibility","visible");
    })

Using 
 didn't work in my fb app. However this did, beautifully (in Chrome FF and IE):

<img src="'../images/foo.gif'" title="line 1&lt;br&gt;line 2">

Easily change without any headche Convert any object array to string array Object drivex[] = {1,2};

    for(int i=0; i<drive.length ; i++)
        {
            Str[i]= drivex[i].toString();
            System.out.println(Str[i]); 
        }

It should not happen. However, when .NET is under a heavy load, it is possible to get duplicate guids. I have two different web servers using two different sql servers. I went to merge the data and found I had 15 million guids and 7 duplicates.

Delete all PODs in all Namespace only (restart deployment)

Since this is the first question from Google I'll add the JavaScript style typeof alternative here as well:

myObject.getClass().getName() // String

For route controller method we have to define only one route. In get or post method we have to define the route separately.

And the resources method is used to creates multiple routes to handle a variety of Restful actions.

Here the Laravel documentation about this.

To Hide the Action Bar add the below code in Values/Styles

<style name="CustomActivityThemeNoActionBar" parent="@android:style/Theme.Holo.Light">
    <item name="android:windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>
</style>

Then in your AndroidManifest.xml file add the below code in the required activity

<activity
        android:name="com.newbelievers.android.NBMenu"
        android:label="@string/title_activity_nbmenu"
        android:theme="@style/CustomActivityThemeNoActionBar">
</activity>

This is not your answer and this is an alternate way to process the form submission

$('.signinform').click(function(e) { 
      e.preventDefault();
      $.ajax({
      type: "POST",
      url: 'index.php/user/signin', // target element(s) to be updated with server response 
      dataType:'json',
      success : function(response){ console.log(response); alert(response)}
     });
}); 

Put this code somewhere in your C++ project:

#ifdef _DEBUG
TCHAR version[50];
sprintf(&version[0], "Version = %d", _MSC_VER);
MessageBox(NULL, (LPCTSTR)szMsg, "Visual Studio", MB_OK | MB_ICONINFORMATION);
#endif

Note that _MSC_VER symbol is Microsoft specific. Here you can find a list of Visual Studio versions with the value for _MSC_VER for each version.

Try using anaconda. I had the same error. One lone option was to build tensorflow from source which took long time. I tried using conda and it worked.

1. Create a new environment in anaconda.
2. conda -c conda-forge tensorflow

Then, it worked.

Why not create symlinks the other way around? Meaning instead of linking from the Git repository to the application directory, just link the other way around.

For example, let’s say I am setting up an application installed in ~/application that needs a configuration file config.conf:

• I add config.conf to my Git repository, for example, at ~/repos/application/config.conf.
• Then I create a symlink from ~/application by running ln -s ~/repos/application/config.conf.

This approach might not always work, but it worked well for me so far.

The explanation for this behavior is right in the javadoc for afterExecute:

Note: When actions are enclosed in tasks (such as FutureTask) either explicitly or via methods such as submit, these task objects catch and maintain computational exceptions, and so they do not cause abrupt termination, and the internal exceptions are not passed to this method.

Java

The Robot class will work much more efficiently than sending the keys through Selenium sendkeys. Please try:

Example:

Robot rb = new Robot();
rb.keyPress(KeyEvent.VK_CONTROL);
rb.keyPress(KeyEvent.VK_A);

To use the above Robot class, you need to import java.awt.Robot;'.

Try:

name = "^aH^ai"
name = name:gsub("%^a", "")

Here is what I ended up doing to work around the error.

First, I set up the database recovery model as SIMPLE. More information here.

Then, by deleting some old files I was able to make 5GB of free space which gave the log file more space to grow.

I reran the DELETE statement sucessfully without any warning.

I thought that by running the DELETE statement the database would inmediately become smaller thus freeing space in my hard drive. But that was not true. The space freed after a DELETE statement is not returned to the operating system inmediatedly unless you run the following command:

DBCC SHRINKDATABASE (MyDb, 0);
GO

More information about that command here.

If you don't want to use API 21 you can use the older version of appcompact library, use older app compact library without updating it.

you can achieve this by simply following steps:

1) Extract the downloaded version of complete sdk and eclipse bundle.

2) Simply import appCompact library from sdk\extras\android\support\v7\appcompact

now you are done.

This happened to me when a stored procedure running in SSMS encountered an error during the loop, while the cursor was in use to iterate over records and before the it was closed. To fix it I added extra code in the CATCH block to close the cursor if it is still open (using CURSOR_STATUS as other answers here suggest).

I was also suffered by same problem. I resolved the problem by reinstalling anaconda(While installation at this time I selected "just for me" as user) and my problem was solved.Try the same

=arrayformula(if(isblank(B2:B),iferror(1/0),mmult(sign(B2:B=TRANSPOSE(A2:A)),A2:A)))

I got this from a good tutorial - can't remember the title - probably about using MMult

Your code is OK. Note though that if you return a pointer to an array, and that array goes out of scope, you should not use that pointer anymore. Example:

int* test (void)
{
    int out[5];
    return out;
}

The above will never work, because out does not exist anymore when test() returns. The returned pointer must not be used anymore. If you do use it, you will be reading/writing to memory you shouldn't.

In your original code, the arr array goes out of scope when main() returns. Obviously that's no problem, since returning from main() also means that your program is terminating.

If you want something that will stick around and cannot go out of scope, you should allocate it with new:

int* test (void)
{
    int* out = new int[5];
    return out;
}

The returned pointer will always be valid. Remember do delete it again when you're done with it though, using delete[]:

int* array = test();
// ...
// Done with the array.
delete[] array;

Deleting it is the only way to reclaim the memory it uses.

The ComboBox control inherits from the ListControl control.

The SelectedItem property is a proper member of the ComboBox control. The event that is fired on change is ComboBox.SelectionChangeCommitted

ComboBox.SelectionChangeCommitted

Occurs when the selected item has changed and that change is displayed in the ComboBox.

The SelectedValue property is inherited from the ListControl control. As such, this property will fire the ListControl.SelectedValueChanged event.

ListControl.SelectedValueChanged

Occurs when the SelectedValue property changes.

That said, they won't fire the INotifyPropertyChanged.PropertyChanged event the same, but they will anyway. The only difference is in the firing event. SelectedValueChanged is fired as soon as a new selection is made from the list part of the ComboBox, and SelectedItemChanged is fired when the item is displayed in the TextBox portion of the ComboBox.

In short, they both represent something in the list part of the ComboBox. So, when binding either property, the result is the same, since the PropertyChanged event is fired in either case. And since they both represent an element from the list, the they are probably treated the same.

Does this help?

EDIT #1

Assuming that the list part of the ComboBox represents a property (as I can't confirm since I didn't write the control), binding either of SelectedItem or SelectedValue affects the same collection inside the control. Then, when this property is changed, the same occurs in the end. The INotifyPropertryPropertyChanged.PropertyChanged event is fired on the same property.

The original answer the author gave works pretty well. Just to extend this idea, you can do something like

group by datediff(minute, 0, [Date])/10

which will allow you to group by a longer period then 60 minutes, say 720, which is half a day etc.

An alternative package that you can use is readxl. This package don't require external dependencies.

I got this error after I changed my model (code first) as follows:

public DateTime? DateCreated

to

public DateTime DateCreated

Present rows with null-value in DateCreated caused this error. So I had to use SQL UPDATE Statement manually for initializing the field with a standard value.

Another solution could be a specifying of the default value for the filed.

You can use NestedScrollView instead of ScrollView. However, when using a Kotlin Lambda, it won't know you want NestedScrollView's setOnScrollChangeListener instead of the one at View (which is API level 23). You can fix this by specifying the first parameter as a NestedScrollView.

nestedScrollView.setOnScrollChangeListener { _: NestedScrollView, scrollX: Int, scrollY: Int, _: Int, _: Int ->
    Log.d("ScrollView", "Scrolled to $scrollX, $scrollY")
}

Please note that you must install the driver for the version of your software client(MS access) not the version of the OS. that's mean that if your MS Access is a 32-bits version,you must install a 32-bit odbc driver. regards

I like to use the semicolons only for the WHILE statement, and the && operator to make the loop do more than one thing...

So I always do it like this

while true ; do echo Launching Spaceship into orbit && sleep 5s && /usr/bin/launch-mechanism && echo Launching in T-5 && sleep 1s && echo T-4 && sleep 1s && echo T-3 && sleep 1s && echo T-2 && sleep 1s && echo T-1 && sleep 1s && echo liftoff ; done

After a restart I could not connect with the local mariadb, a search also brought me to this page and I wanted to share my solution with you.

I noticed that the directory my.cnf.d in /usr/local/etc/ is missing.

This is a known bug with homebrew that is described and solved there. https://github.com/Homebrew/homebrew-core/issues/36801

fast way to fix: mkdir /usr/local/etc/my.cnf.d

I had a semicolon at the end, and gave me this error.

Step 1: Modify package.json file to include lodash in the dependencies.

  "dependencies": {
"@angular/common":  "2.0.0-rc.1",
"@angular/compiler":  "2.0.0-rc.1",
"@angular/core":  "2.0.0-rc.1",
"@angular/http":  "2.0.0-rc.1",
"@angular/platform-browser":  "2.0.0-rc.1",
"@angular/platform-browser-dynamic":  "2.0.0-rc.1",
"@angular/router":  "2.0.0-rc.1",
"@angular/router-deprecated":  "2.0.0-rc.1",
"@angular/upgrade":  "2.0.0-rc.1",
"systemjs": "0.19.27",

"zone.js": "^0.6.12",
"lodash":"^4.12.0",
"angular2-in-memory-web-api": "0.0.7",
"bootstrap": "^3.3.6"  }

Step 2:I am using SystemJs module loader in my angular2 application. So I would be modifying the systemjs.config.js file to map lodash.

(function(global) {

// map tells the System loader where to look for things
var map = {
    'app':                        'app', // 'dist',
    'rxjs':                       'node_modules/rxjs',
    'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
    '@angular':                   'node_modules/@angular',
    'lodash':                    'node_modules/lodash'
};

// packages tells the System loader how to load when no filename and/or no extension
var packages = {
    'app':                        { main: 'main.js',  defaultExtension: 'js' },

});

var config = {
    map: map,
    packages: packages
}

// filterSystemConfig - index.html's chance to modify config before we register it.
if (global.filterSystemConfig) { global.filterSystemConfig(config); }

System.config(config);})(this);

Step 3: Now do npm install

Step 4: To use lodash in your file.

import * as _ from 'lodash';
let firstIndexOfElement=_.findIndex(array,criteria);

As from MSDN for GetChanges

A filtered copy of the DataTable that can have actions performed on it, and later be merged back in the DataTable using Merge. If no rows of the desired DataRowState are found, the method returns Nothing (null).

dataTable1 is null so just check before you iterate over it.

For python, use the

from selenium.webdriver import ActionChains

and

ActionChains(browser).click(element).perform()

I was facing a similar issue, I had a file on my project, and wanted to test a class which had to deal with loading files from the FS and process them some way. What I did was:

• added the file test.txt to my test project
• on the solution explorer hit alt-enter (file properties)
• there I set BuildAction to Content and Copy to Output Directory to Copy if newer, I guess Copy always would have done it as well

then on my tests I just had to Path.Combine(Environment.CurrentDirectory, "test.txt") and that's it. Whenever the project is compiled it will copy the file (and all it's parent path, in case it was in, say, a folder) to the bin\Debug (or whatever configuration you are using) folder.

Hopes this helps someone

SQL Server and the .NET Framework are based on different type systems. For example, the .NET Framework Decimal structure has a maximum scale of 28, whereas the SQL Server decimal and numeric data types have a maximum scale of 38. Click Here's a link! for detail

It depends on how you want to use the data in the excel file. If you want to import it into mysql, you could simply save it as a CSV formatted file and then use fgetcsv to parse it.

If possible, check out SSIS (SQL Server Integration Services). I am just getting my feet wet with this toolkit, but already am looping over 40+ servers and preparing to wreak all kinds of havoc ;)

This does not answer the question directly, but I have on different occasions landed on this Stack Overflow question in order to solve something I would use $watch for in angularJs. I ended up using another approach than described in the current answers, and want to share it in case someone finds it useful.

The technique I use to achieve something similar $watch is to use a BehaviorSubject (more on the topic here) in an Angular service, and let my components subscribe to it in order to get (watch) the changes. This is similar to a $watch in angularJs, but require some more setup and understanding.

In my component:

export class HelloComponent {
  name: string;
  // inject our service, which holds the object we want to watch.
  constructor(private helloService: HelloService){
    // Here I am "watching" for changes by subscribing
    this.helloService.getGreeting().subscribe( greeting => {
      this.name = greeting.value;
    });
  }
}

In my service

export class HelloService {
  private helloSubject = new BehaviorSubject<{value: string}>({value: 'hello'});
  constructor(){}
  // similar to using $watch, in order to get updates of our object 
  getGreeting(): Observable<{value:string}> {
    return this.helloSubject;
  }
  // Each time this method is called, each subscriber will receive the updated greeting.
  setGreeting(greeting: string) {
    this.helloSubject.next({value: greeting});
  }
}

Here is a demo on Stackblitz

Let's dissect it. There are three parts:

1. cd -- This is change directory command.
2. /d -- This switch makes cd change both drive and directory at once. Without it you would have to do cd %~d0 & cd %~p0. (%~d0 Changs active drive, cd %~p0 change the directory).
3. %~dp0 -- This can be dissected further into three parts:
   1. %0 -- This represents zeroth parameter of your batch script. It expands into the name of the batch file itself.
   2. %~0 -- The ~ there strips double quotes (") around the expanded argument.
   3. %dp0 -- The d and p there are modifiers of the expansion. The d forces addition of a drive letter and the p adds full path.

You can change the mysql root password by logging in to the database directly (mysql -h your_host -u root) then run

SET PASSWORD FOR root@localhost = PASSWORD('yourpassword');

You can use below script to get the output to csv files. One file per table with headers.

for tn in `mysql --batch --skip-page --skip-column-name --raw -uuser -ppassword -e"show tables from mydb"`
do 
mysql -uuser -ppassword mydb -B -e "select * from \`$tn\`;" | sed 's/\t/","/g;s/^/"/;s/$/"/;s/\n//g' > $tn.csv
done

user is your user name, password is the password if you don't want to keep typing the password for each table and mydb is the database name.

Explanation of the script: The first expression in sed, will replace the tabs with "," so you have fields enclosed in double quotes and separated by commas. The second one insert double quote in the beginning and the third one insert double quote at the end. And the final one takes care of the \n.

While I found the two top-upvoted answers useful on other occasions, today, the simplest way to resolve the issue was to realize that PyCharm might be keeping a session open, and if I clicked Stop in PyCharm, that might help. With pgAdmin4 open in the browser, I did so, and almost immediately saw the Database sessions stats drop to 0, at which point I was able to drop the database.

Deleting/Moving tablename.ibd sure did not work for me.

How I solved it

Since I was going to delete the corrupted and non existing table, I took a backup of the other tables by going to phpmyadmin->database->export->selected tables to backup->export(as .sql).

After that I selected the database icon next to database name and then dropped it. Created a new database. Select your new database->import-> Select the file you downloaded earlier->click import. Now I have my old working tables and have the corrupted table deleted. Now I just create the table that was throwing the error.

Likely I had an earlier backup of the corrupted table.

}

Short answer: Yes, you need to rename .cpp files to c, so you can write C: https://msdn.microsoft.com/en-us/library/bb384838.aspx?f=255&MSPPError=-2147217396

From the link above:

By default, the Visual C++ compiler treats all files that end in .c as C source code, and all files that end in .cpp as C++ source code. To force the compiler to treat all files as C regardless of file name extension, use the /Tc compiler option.

That being said, I do not recommend learning C language in Visual Studio, why VS? It does have lots of features you are not going to use while learning C

Use:

var hovered = $("#parent").find("#element:hover").length;

jQuery 1.9+

Either in your admin.py or in a separate forms.py you can add a ModelForm class and then declare your extra fields inside that as you normally would. I've also given an example of how you might use these values in form.save():

from django import forms
from yourapp.models import YourModel


class YourModelForm(forms.ModelForm):

    extra_field = forms.CharField()

    def save(self, commit=True):
        extra_field = self.cleaned_data.get('extra_field', None)
        # ...do something with extra_field here...
        return super(YourModelForm, self).save(commit=commit)

    class Meta:
        model = YourModel

To have the extra fields appearing in the admin just:

1. edit your admin.py and set the form property to refer to the form you created above
2. include your new fields in your fields or fieldsets declaration

Like this:

class YourModelAdmin(admin.ModelAdmin):

    form = YourModelForm

    fieldsets = (
        (None, {
            'fields': ('name', 'description', 'extra_field',),
        }),
    )

UPDATE: In django 1.8 you need to add fields = '__all__' to the metaclass of YourModelForm.

In my case it's because the permission for my home directory is 775, and SSH is not happy about it. It should work after executing:

server$ chmod go-w ~/
server$ chmod 700 ~/.ssh
server$ chmod 600 ~/.ssh/authorized_keys

I had very similar experience this afternoon. I was setting up django on EC2, and suddenly I cannot SSH into the box anymore. Glad I still had an active connection, so I modified /etc/ssh/sshd_config to set:

PasswordAuthentication yes

and set password for ec2-user, then I can login by entering the password.

However, after some googling I found this thread: http://ubuntuforums.org/showthread.php?t=577279. It turned out that during my setup of django I changed the permission for my home directory, and SSH is very strict about this. So the file permission must be set correctly.

SELECT * FROM permlog ORDER BY id DESC LIMIT 0, 1

Using this you can avoid the loop.

// obj is the params object with key-value pair. 
// This is how you convert that to HttpParams and pass this to GET API. 

const params = Object.getOwnPropertyNames(obj)
               .reduce((p, key) => p.set(key, obj[key]), new HttpParams());

Furthermore, I suggest making toHttpParams function in your commonly used service. So you can call the function to convert the object to the HttpParams.

/**
 * Convert Object to HttpParams
 * @param {Object} obj
 * @returns {HttpParams}
 */
toHttpParams(obj: Object): HttpParams {
    return Object.getOwnPropertyNames(obj)
        .reduce((p, key) => p.set(key, obj[key]), new HttpParams());
}

Update:

Since 5.0.0-beta.6 (2017-09-03) they added new feature (accept object map for HttpClient headers & params)

Going forward the object can be passed directly instead of HttpParams.

This is the other reason if you have used one common function like toHttpParams mentioned above, you can easily remove it or do changes if required.

I faced the exact same problem. This problem occurred when I cloned using HTTPS URL and then tried to push the changes using Git Bash on Windows using:

git clone https://github.com/{username}/{repo}.git

However, when I used SSH URL to clone, this problem didn't occur:

git clone [email protected]:{username}/{repo}.git

Flex is the better way. Just try..

display: flex;

While it is not free (but $39), FireDaemon has worked so well for me I have to recommend it. It will run your batch file but has loads of additional and very useful functionality such as scheduling, service up monitoring, GUI or XML based install of services, dependencies, environmental variables and log management.

I started out using FireDaemon to launch JBoss application servers (run.bat) but shortly after realized that the richness of the FireDaemon configuration abilities allowed me to ditch the batch file and recreate the intent of its commands in the FireDaemon service definition.

There's also a SUPER FireDaemon called Trinity which you might want to look at if you have a large number of Windows servers on which to manage this service (or technically, any service).

One requirement for remote debugging is that the windows account used to run SSMS be part of the sysadmin role. See this MSDN link: http://msdn.microsoft.com/en-us/library/cc646024%28v=sql.105%29.aspx

It seems that you have invalid JSON. In that case, that's totally dependent on the data the server sends you which you have not shown. I would suggest running the response through a JSON validator.

Modal Window using ExtJS approach.

In Main Window

<html>
<link rel="stylesheet" href="ext.css" type="text/css">
<head>    
<script type="text/javascript" src="ext-all.js"></script>

function openModalDialog() {
    Ext.onReady(function() {
        Ext.create('Ext.window.Window', {
        title: 'Hello',
        height: Ext.getBody().getViewSize().height*0.8,
        width: Ext.getBody().getViewSize().width*0.8,
        minWidth:'730',
        minHeight:'450',
        layout: 'fit',
        itemId : 'popUpWin',        
        modal:true,
        shadow:false,
        resizable:true,
        constrainHeader:true,
        items: [{

            autoEl: {
                     tag: 'iframe',
                     src: '2.html',
                     frameBorder:'0'
            }
        }]
        }).show();
  });
}
function closeExtWin(isSubmit) {
     Ext.ComponentQuery.query('#popUpWin')[0].close();
     if (isSubmit) {
          document.forms[0].userAction.value = "refresh";
          document.forms[0].submit();
    }
}
</head>
<body>
   <form action="abc.jsp">
   <a href="javascript:openModalDialog()"> Click to open dialog </a>
   </form>
</body>
</html>

In popupWindow 2.html

<html>
<head>
<script type="text\javascript">
function doSubmit(action) {
     if (action == 'save') {
         window.parent.closeExtWin(true);
     } else {
         window.parent.closeExtWin(false);
     }   
}
</script>
</head>

Problem with the above answer comes with files input with "./" like "./my-file.txt"

Workaround (of many):

    myfile="./somefile.txt"
    FOLDER="$(dirname $(readlink -f "${ARG}"))"
    echo ${FOLDER}

on php7 run for example:

> sudo apt-get install php-curl
> sudo apt-get install php-mbstring

for every missing extension. Then:

> sudo apt-get update

and finally (in the project's root folder):

> composer install

You could use DATE_ADD : (or ADDDATE with INTERVAL)

UPDATE table SET date = DATE_ADD(date, INTERVAL 1 YEAR) 

This script demonstrates a few ways to show the local timezone using astimezone():

#!/usr/bin/env python3

import pytz
from datetime import datetime, timezone
from tzlocal import get_localzone

utc_dt = datetime.now(timezone.utc)

PST = pytz.timezone('US/Pacific')
EST = pytz.timezone('US/Eastern')
JST = pytz.timezone('Asia/Tokyo')
NZST = pytz.timezone('Pacific/Auckland')

print("Pacific time {}".format(utc_dt.astimezone(PST).isoformat()))
print("Eastern time {}".format(utc_dt.astimezone(EST).isoformat()))
print("UTC time     {}".format(utc_dt.isoformat()))
print("Japan time   {}".format(utc_dt.astimezone(JST).isoformat()))

# Use astimezone() without an argument
print("Local time   {}".format(utc_dt.astimezone().isoformat()))

# Use tzlocal get_localzone
print("Local time   {}".format(utc_dt.astimezone(get_localzone()).isoformat()))

# Explicitly create a pytz timezone object
# Substitute a pytz.timezone object for your timezone
print("Local time   {}".format(utc_dt.astimezone(NZST).isoformat()))

It outputs the following:

$ ./timezones.py 
Pacific time 2019-02-22T17:54:14.957299-08:00
Eastern time 2019-02-22T20:54:14.957299-05:00
UTC time     2019-02-23T01:54:14.957299+00:00
Japan time   2019-02-23T10:54:14.957299+09:00
Local time   2019-02-23T14:54:14.957299+13:00
Local time   2019-02-23T14:54:14.957299+13:00
Local time   2019-02-23T14:54:14.957299+13:00

As of python 3.6 calling astimezone() without a timezone object defaults to the local zone (docs). This means you don't need to import tzlocal and can simply do the following:

#!/usr/bin/env python3

from datetime import datetime, timezone

utc_dt = datetime.now(timezone.utc)

print("Local time {}".format(utc_dt.astimezone().isoformat()))

If you are using eGit in Eclipse:

• Right click on the project node.
• Choose Team ? then Advanced ? then Rename branch
• Then expand the remote tracking folder.
• Choose the branch with the wrong name, then click the rename button, rename it to whatever the new name.
• Choose the new master, then rename it to master.

SessionState

• Can be persisted in memory, which makes it a fast solution. Which means state cannot be shared in the Web Farm/Web Garden.
• Can be persisted in a Database, useful for Web Farms / Web Gardens.
• Is Cleared when the session dies - usually after 20min of inactivity.

ViewState

• Is sent back and forth between the server and client, taking up bandwidth.
• Has no expiration date.
• Is useful in a Web Farm / Web Garden

You can also get SIGBUS when a code page cannot be paged in for some reason.

On *nix, you can use comm. The answer to the question is:

comm -1 -2 file1.sorted file2.sorted 
# where file1 and file2 are sorted and piped into *.sorted

Here's the full usage of comm:

comm [-1] [-2] [-3 ] file1 file2
-1 Suppress the output column of lines unique to file1.
-2 Suppress the output column of lines unique to file2.
-3 Suppress the output column of lines duplicated in file1 and file2. 

Also note that it is important to sort the files before using comm, as mentioned in the man pages.

One (dirty) way to do it is to use tryCatch with an empty function for error handling. For example, the following code raises an error and breaks the loop :

for (i in 1:10) {
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
Erreur : Urgh, the iphone is in the blender !

But you can wrap your instructions into a tryCatch with an error handling function that does nothing, for example :

for (i in 1:10) {
  tryCatch({
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
  }, error=function(e){})
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
[1] 8
[1] 9
[1] 10

But I think you should at least print the error message to know if something bad happened while letting your code continue to run :

for (i in 1:10) {
  tryCatch({
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
  }, error=function(e){cat("ERROR :",conditionMessage(e), "\n")})
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
ERROR : Urgh, the iphone is in the blender ! 
[1] 8
[1] 9
[1] 10

EDIT : So to apply tryCatch in your case would be something like :

for (v in 2:180){
    tryCatch({
        mypath=file.path("C:", "file1", (paste("graph",names(mydata[columnname]), ".pdf", sep="-")))
        pdf(file=mypath)
        mytitle = paste("anything")
        myplotfunction(mydata[,columnnumber]) ## this function is defined previously in the program
        dev.off()
    }, error=function(e){cat("ERROR :",conditionMessage(e), "\n")})
}

You have to overrride the scale, try this: (applies to ChartJS v1.x)

window.onload = function(){
    var ctx = document.getElementById("canvas").getContext("2d");
    window.myLine = new Chart(ctx).Line(lineChartData, {
        scaleOverride : true,
        scaleSteps : 10,
        scaleStepWidth : 50,
        scaleStartValue : 0 
    });
}

It's an indication that connection pooling is being used (which is a good thing).

You need to run the script as source or the shorthand .

source ./myscript.sh

or

. ./myscript.sh

This will run within the existing shell, ensuring any variables created or modified by the script will be available after the script completes.

Running the script just using the filename will execute the script in a separate subshell.

Solution without page reload

<?php
  function removeday() { echo 'Day removed'; }

  if (isset($_GET['remove'])) { return removeday(); }
?>


<!DOCTYPE html><html><title>Days</title><body>

  <a href="" onclick="removeday(event)" class="deletebtn">Delete</a>

  <script>
  async function removeday(e) {
    e.preventDefault(); 
    document.body.innerHTML+= '<br>'+ await(await fetch('?remove=1')).text();
  }
  </script>

</body></html>

Other solutions on this page aren't desirable if you have a long list of extensions -- maintaining a long sequence of -not -name 'this' -not -name 'that' -not -name 'other' would be tedious and error-prone -- or if the search is programmatic and the list of extensions is built at runtime.

For those situations, a solution that more clearly separates data (the list of extensions) and code (the parameters to find) may be desirable. Given a directory & file structure that looks like this:

.
+-- a
    +-- 1.txt
    +-- 15.xml
    +-- 8.dll
    +-- b
    ¦   +-- 16.xml
    ¦   +-- 2.txt
    ¦   +-- 9.dll
    ¦   +-- c
    ¦       +-- 10.dll
    ¦       +-- 17.xml
    ¦       +-- 3.txt
    +-- d
    ¦   +-- 11.dll
    ¦   +-- 18.xml
    ¦   +-- 4.txt
    ¦   +-- e
    ¦       +-- 12.dll
    ¦       +-- 19.xml
    ¦       +-- 5.txt
    +-- f
        +-- 13.dll
        +-- 20.xml
        +-- 6.txt
        +-- g
            +-- 14.dll
            +-- 21.xml
            +-- 7.txt

You can do something like this:

## data section, list undesired extensions here
declare -a _BADEXT=(xml dll)

## code section, this never changes
BADEXT="$( IFS="|" ; echo "${_BADEXT[*]}" | sed 's/|/\\|/g' )"
find . -type f ! -regex ".*\.\($BADEXT\)"

Which results in:

./a/1.txt
./a/b/2.txt
./a/b/c/3.txt
./a/d/4.txt
./a/d/e/5.txt
./a/f/6.txt
./a/f/g/7.txt

You can change the extensions list without changing the code block.

NOTE doesn't work with native OSX find - use gnu find instead.

Go to file \phpMyAdmin\config.inc.php at the very bottom, change the hosting details such as host, username, password etc.

Select-Object returns a custom PSObject with just the properties specified. Even with a single property, you don't get the ACTUAL variable; it is wrapped inside the PSObject.

Instead, do:

Get-Date | Select-Object -ExpandProperty DayOfWeek

That will get you the same result as:

(Get-Date).DayOfWeek

The difference is that if Get-Date returns multiple objects, the pipeline way works better than the parenthetical way as (Get-ChildItem), for example, is an array of items. This has changed in PowerShell v3 and (Get-ChildItem).FullPath works as expected and returns an array of just the full paths.

Something like this should remove it

document.getElementById('x').style.visibility='hidden';

If you are going to do alot of this dom manipulation might be worth looking at jquery

You cannot initialize an array to '0' like that

int cipher[Array_size][Array_size]=0;

You can either initialize all the values in the array as you declare it like this:

// When using different values
int a[3] = {10,20,30};

// When using the same value for all members
int a[3] = {0};

// When using same value for all members in a 2D array
int a[Array_size][Array_size] = { { 0 } };

Or you need to initialize the values after declaration. If you want to initialize all values to 0 for example, you could do something like:

for (int i = 0; i < Array_size; i++ ) {
    a[i] = 0;
}

I wrote next method as my solution (I hadn't any load indicator):

public static void waitForAjax(WebDriver driver, String action) {
       driver.manage().timeouts().setScriptTimeout(5, TimeUnit.SECONDS);
       ((JavascriptExecutor) driver).executeAsyncScript(
               "var callback = arguments[arguments.length - 1];" +
                       "var xhr = new XMLHttpRequest();" +
                       "xhr.open('POST', '/" + action + "', true);" +
                       "xhr.onreadystatechange = function() {" +
                       "  if (xhr.readyState == 4) {" +
                       "    callback(xhr.responseText);" +
                       "  }" +
                       "};" +
                       "xhr.send();");
}

Then I jsut called this method with actual driver. More description in this post.

Likely you have bad data that cannot convert. Dates should never be stored in varchar becasue it will allow dates such as ASAP or 02/30/2009. Use the isdate() function on your data to find the records which can't convert.

OK I tested with known good data and still got the message. You need to convert to a different format becasue it does not know if 12302009 is mmddyyyy or ddmmyyyy. The format of yyyymmdd is not ambiguous and SQL Server will convert it correctly

I got this to work:

cast( right(@date,4) + left(@date,4) as datetime)

You will still get an error message though if you have any that are in a non-standard format like '112009' or some text value or a true out of range date.

Type-safe means that the set of values that may be assigned to a program variable must fit well-defined and testable criteria. Type-safe variables lead to more robust programs because the algorithms that manipulate the variables can trust that the variable will only take one of a well-defined set of values. Keeping this trust ensures the integrity and quality of the data and the program.

For many variables, the set of values that may be assigned to a variable is defined at the time the program is written. For example, a variable called "colour" may be allowed to take on the values "red", "green", or "blue" and never any other values. For other variables those criteria may change at run-time. For example, a variable called "colour" may only be allowed to take on values in the "name" column of a "Colours" table in a relational database, where "red, "green", and "blue", are three values for "name" in the "Colours" table, but some other part of the computer program may be able to add to that list while the program is running, and the variable can take on the new values after they are added to the Colours table.

Many type-safe languages give the illusion of "type-safety" by insisting on strictly defining types for variables and only allowing a variable to be assigned values of the same "type". There are a couple of problems with this approach. For example, a program may have a variable "yearOfBirth" which is the year a person was born, and it is tempting to type-cast it as a short integer. However, it is not a short integer. This year, it is a number that is less than 2009 and greater than -10000. However, this set grows by 1 every year as the program runs. Making this a "short int" is not adequate. What is needed to make this variable type-safe is a run-time validation function that ensures that the number is always greater than -10000 and less than the next calendar year. There is no compiler that can enforce such criteria because these criteria are always unique characteristics of the problem domain.

Languages that use dynamic typing (or duck-typing, or manifest typing) such as Perl, Python, Ruby, SQLite, and Lua don't have the notion of typed variables. This forces the programmer to write a run-time validation routine for every variable to ensure that it is correct, or endure the consequences of unexplained run-time exceptions. In my experience, programmers in statically typed languages such as C, C++, Java, and C# are often lulled into thinking that statically defined types is all they need to do to get the benefits of type-safety. This is simply not true for many useful computer programs, and it is hard to predict if it is true for any particular computer program.

The long & the short.... Do you want type-safety? If so, then write run-time functions to ensure that when a variable is assigned a value, it conforms to well-defined criteria. The down-side is that it makes domain analysis really difficult for most computer programs because you have to explicitly define the criteria for each program variable.

Normally I do like this

 git push https://$(git_token)@github.com/user_name/repo_name.git

The git_token is reading from variable config in azure devops.

Test execution result different from JUnit run and from maven install seems to be symptom for several problems.

Disabling thread reusing test execution did also get rid of the symptom in our case, but the impression that the code was not thread-safe was still strong.

In our case the difference was due to the presence of a bean that modified the test behaviour. Running just the JUnit test would result fine, but running the project install target would result in a failed test case. Since it was the test case under development, it was immediately suspicious.

It resulted that another test case was instantiating a bean through Spring that would survive until the execution of the new test case. The bean presence was modifying the behaviour of some classes and producing the failed result.

The solution in our case was getting rid of the bean, which was not needed in the first place (yet another prize from the copy+paste gun).

I suggest everybody with this symptom to investigate what the root cause is. Disabling thread reuse in test execution might only hide it.

I'm not entirely sure but I think you are probably surprised at how arrays are serialized in JSON. Let's isolate the problem. Consider following code:

var display = Array();
display[0] = "none";
display[1] = "block";
display[2] = "none";

console.log( JSON.stringify(display) );

This will print:

["none","block","none"]

This is how JSON actually serializes array. However what you want to see is something like:

{"0":"none","1":"block","2":"none"}

To get this format you want to serialize object, not array. So let's rewrite above code like this:

var display2 = {};
display2["0"] = "none";
display2["1"] = "block";
display2["2"] = "none";

console.log( JSON.stringify(display2) );

This will print in the format you want.

You can play around with this here: http://jsbin.com/oDuhINAG/1/edit?js,console

To find all system generated unique constraint names and other information related to it on any database.

You may use below query and enhance it as per your need:

SELECT * FROM INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE WHERE CONSTRAINT_NAME LIKE '%UQ%'

Final query to drop all unique constraint through database. You may add where clause to restrict it to one table:

    DECLARE @uqQuery NVARCHAR(MAX)
    SET @uqQuery = SUBSTRING( (SELECT '; ' + 'ALTER TABLE [' + Table_Schema+'].['+Table_Name
        +']  DROP CONSTRAINT ['+CONSTRAINT_NAME+']'

    FROM INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE WHERE CONSTRAINT_NAME LIKE '%UQ%'
    FOR XML PATH('')), 2,  2000000)
    SELECT @uqQuery

Place this line before the closing script tag,writing from memory:

window.onload  = GetTimeZoneOffset;

i think the question is how to call the javascript function on pageload

To manually Request GC (not from System.gc()) :

1. Go To : bin folder in JDK eg.-C:\Program Files\Java\jdk1.6.0_31\bin
2. Open jconsole.exe
3. Connect to the desired local Process.
4. Go To memory tab and click perform GC.

Here you can see the nature of Scanner:

double nextDouble()

Returns the next token as a double. If the next token is not a float or is out of range, InputMismatchException is thrown.

Try to catch the exception

try {
    // ...
} catch (InputMismatchException e) {
    System.out.print(e.getMessage()); //try to find out specific reason.
}

UPDATE

CASE 1

I tried your code and there is nothing wrong with it. Your are getting that error because you must have entered String value. When I entered a numeric value, it runs without any errors. But once I entered String it throw the same Exception which you have mentioned in your question.

CASE 2

You have entered something, which is out of range as I have mentioned above.

I'm really wondering what you could have tried to enter. In my system, it is running perfectly without changing a single line of code. Just copy as it is and try to compile and run it.

import java.util.*;

public class Test {
    public static void main(String... args) {
        new Test().askForMarks(5);
    }

    public void askForMarks(int student) {
        double marks[] = new double[student];
        int index = 0;
        Scanner reader = new Scanner(System.in);
        while (index < student) {
            System.out.print("Please enter a mark (0..30): ");
            marks[index] = (double) checkValueWithin(0, 30); 
            index++;
        }
    }

    public double checkValueWithin(int min, int max) {
        double num;
        Scanner reader = new Scanner(System.in);
        num = reader.nextDouble();                         
        while (num < min || num > max) {                 
            System.out.print("Invalid. Re-enter number: "); 
            num = reader.nextDouble();                         
        } 

        return num;
    }
}

As you said, you have tried to enter 1.0, 2.8 and etc. Please try with this code.

Note : Please enter number one by one, on separate lines. I mean, enter 2.7, press enter and then enter second number (e.g. 6.7).

With a simple JSON object, you don't need jQuery:

for (var i in json) {
   for (var j in json[i]) {
     console.log(json[i][j]);
   }
}

It's because you don't an async response For example:

app.get(`${api}/users`, async (req, res) => {
    const users = await User.find()
    res.send(users);
   })

The two most usual choices are GTK+, which has documentation links here, and is mostly used with C; or Qt which has documentation here and is more used with C++.

I posted these two as you do not specify an operating system and these two are pretty cross-platform.

rbind.fill from the package plyr might be what you are looking for.

Just be careful. You will get this message if you try to enter a command that doesn't exist like this

/usr/bin/java -v

Download whatever configuration script that your browser is using.

the script would have various host:port configuration. based on the domain you want to connect , one of the host:port is selected by the borwser.

in the eclipse network setting you can try to put on of the host ports and see if that works.

worked for me.

the config script looks like,

if (isPlainHostName(host))
    return "DIRECT";
else if (dnsDomainIs(host, "<***sample host name *******>"))
    return "PROXY ***some ip*****; DIRECT";
else if (dnsDomainIs(host, "address.com")
        || dnsDomainIs(host, "adress2..com")
        || dnsDomainIs(host, "address3.com")
        || dnsDomainIs(host, "address4.com")        
    return "PROXY <***some proxyhost****>:8080";

you would need to look for the host port in the return statement.

I had this same issue trying to run a simple tkinter app remotely on a Raspberry Pi. In my case I did want to display the tkinter GUI on the pi display, but I want to be able to execute it over SSH from my host machine. I was also not using matplotlib, so that wasn't the cause of my issue. I was able to resolve the issue by setting the DISPLAY environment variable as the error suggests with the command:

export DISPLAY=:0.0

A good explanation of what the display environment variable is doing and why the syntax is so odd can be found here: https://askubuntu.com/questions/432255/what-is-display-environment-variable

My solution was to change the run configurations module drop-down list from wearable to android. (This error happened to me when I tried running Google's I/O Sched open-source app.) It would automatically pop up the configurations every time I tried to run until I changed the module to android.

You can access the configurations by going to Run -> Edit Configurations... -> General tab -> Module: [drop-down-list-here]

How about

if (dr.GetSchemaTable().Columns.Contains("accounttype"))
   do something
else
   do something

It probably would not be as efficient in a loop

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.

To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".

To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".

Explanation:

From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):

4.3.8 ‘Local echo’

With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)

Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.

4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.

If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.

Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)

Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.

Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

You would need to attach your click event to some element. If there are lots of other elements on the page you would not want to attach a click event to all of them.

One potential way would be to create a transparent div below your dropdown menu but above all other elements on the page. You would show it when the drop down was shown. Have the element have a click hander that hides the drop down and the transparent div.

$('#clickCatcher').click(function () { _x000D_
  $('#dropContainer').hide();_x000D_
  $(this).hide();_x000D_
});

#dropContainer { z-index: 101; ... }_x000D_
#clickCatcher { position: absolute; top: 0; left: 0; width: 100%; height: 100%; z-index: 100; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="dropDown"></div>_x000D_
<div id="clickCatcher"></div>

Use this,

AppCompatActivity activity = (AppCompatActivity) view.getContext();
Fragment myFragment = new MyFragment();
activity.getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, myFragment).addToBackStack(null).commit();

Since 1.10 release, you can now add multiple tags at once on build:

docker build -t name1:tag1 -t name1:tag2 -t name2 .

Source: Add ability to add multiple tags with docker build

Docker cp command is a handy utility that allows to copy files and folders between a container and the host system.

If you want to copy files from your host system to the container, you should use docker cp command like this:

docker cp host_source_path container:destination_path

List your running containers first using docker ps command:

abhishek@linuxhandbook:~$ sudo docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              
  PORTS               NAMES
  8353c6f43fba        775349758637        "bash"              8 seconds ago       Up 7 
  seconds                            ubu_container

You need to know either the container ID or the container name. In my case, the docker container name is ubu_container. and the container ID is 8353c6f43fba.

If you want to verify that the files have been copied successfully, you can enter your container in the following manner and then use regular Linux commands:

docker exec -it ubu_container bash

Copy files from host system to docker container Copying with docker cp is similar to the copy command in Linux.

I am going to copy a file named a.py to the home/dir1 directory in the container.

docker cp a.py ubu_container:/home/dir1

If the file is successfully copied, you won’t see any output on the screen. If the destination path doesn’t exist, you would see an error:

abhishek@linuxhandbook:~$ sudo docker cp a.txt ubu_container:/home/dir2/subsub
        Error: No such container:path: ubu_container:/home/dir2

If the destination file already exists, it will be overwritten without any warning.

You may also use container ID instead of the container name:

docker cp a.py 8353c6f43fba:/home/dir1

I have successfully used the Enterprise DT FTP library, which is free and open source. I can't compare it to other libraries (like the Apache Commons Net library) since I haven't used them. It does provide a simple upgrade path to SFTP (over SSH) and FTPS (over SSL), though that is a pay-for commercial product.

So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]

To find a hostname in your local network by IP address you can use:

nmblookup -A <ip>

To find a hostname on the internet you could use the host program:

host <ip>

Or you can install nbtscan by running:

sudo apt-get install nbtscan

And use:

nbtscan <ip>

*Taken from https://askubuntu.com/questions/205063/command-to-get-the-hostname-of-remote-server-using-ip-address/205067#205067

You can query a name server with nslookup. It works both ways!

nslookup <IP>
nslookup <hostname>

Smart Pointers are those where you don't have to worry about Memory De-Allocation, Resource Sharing and Transfer.

You can very well use these pointer in the similar way as any allocation works in Java. In java Garbage Collector does the trick, while in Smart Pointers, the trick is done by Destructors.

You can access Current logged in user by using the following code:

request.user.id

You declared activity A with the standard launchMode in the Android manifest. According to the documentation, that means the following:

The system always creates a new instance of the activity in the target task and routes the intent to it.

Therefore, the system is forced to recreate activity A (i.e. calling onCreate) even if the task stack is handled correctly.

To fix this problem you need to change the manifest, adding the following attribute to the A activity declaration:

android:launchMode="singleTop"

Note: calling finish() (as suggested as solution before) works only when you are completely sure that the activity B instance you are terminating lives on top of an instance of activity A. In more complex workflows (for instance, launching activity B from a notification) this might not be the case and you have to correctly launch activity A from B.

Jeffrey L Whitledge is right. Your `dataList´-Object itself is null.

There is also another problem with your code: You are using the ref-keyword, which means the argument data cannot be null! The MSDN says:

An argument passed to a ref parameter must first be initialized. This differs from out, whose arguments do not have to be explicitly initialized before they are passed

It's also not a good idea to use generics with the type `Object´. Generics should avoid boxing/unboxing and also ensure type safety. If you want a common type make your method generic. Finally your code should look like this:

public class Foo<T> where T : MyTypeOrInterface {

      public List<T> dataList = new List<T>();

      public bool AddData(ref T data) {
        bool success = false;
        try {
          dataList.Add(data);                   
          success = doOtherStuff(data);
        } catch (Exception e) {
          throw new Exception(e.ToString());
        }
        return success;
      }

      private bool doOtherStuff(T data) {
        //...
      }
    }

There is a way to make youtube autoplay, and complete playlists play through. Get Adblock browser for Android, and then go to the youtube website, and and configure it for the desktop version of the page, close Adblock browser out, and then reopen, and you will have the desktop version, where autoplay will work.

Using the desktop version will also mean that AdBlock will work. The mobile version invokes the standalone YouTube player, which is why you want the desktop version of the page, so that autoplay will work, and so ad blocking will work.

You are probably looking for System.Guid.NewGuid().

While I haven't found a good way to specify proxy network credentials in the web.config, you might find that you can still use a non-coding solution, by including this in your web.config:

  <system.net>
    <defaultProxy useDefaultCredentials="true">
      <proxy proxyaddress="proxyAddress" usesystemdefault="True"/>
    </defaultProxy>
  </system.net>

The key ingredient in getting this going, is to change the IIS settings, ensuring the account that runs the process has access to the proxy server. If your process is running under LocalService, or NetworkService, then this probably won't work. Chances are, you'll want a domain account.

For me worked when I changed "directory" content into this:

<Directory  "*YourLocation*">
Options All
AllowOverride All
Require all granted  
</Directory>

Granted, the answer I linked in the comments is not very helpful. You can specify your own string converter like so.

In [25]: pd.set_option('display.float_format', lambda x: '%.3f' % x)

In [28]: Series(np.random.randn(3))*1000000000
Out[28]: 
0    -757322420.605
1   -1436160588.997
2   -1235116117.064
dtype: float64

I'm not sure if that's the preferred way to do this, but it works.

Converting numbers to strings purely for aesthetic purposes seems like a bad idea, but if you have a good reason, this is one way:

In [6]: Series(np.random.randn(3)).apply(lambda x: '%.3f' % x)
Out[6]: 
0     0.026
1    -0.482
2    -0.694
dtype: object

Just use in the CSS whatever you would use in a fill attribute. Of course, this requires that you have defined the linear gradient somewhere in your SVG.

Here is a complete example:

rect {_x000D_
    cursor: pointer;_x000D_
    shape-rendering: crispEdges;_x000D_
    fill: url(#MyGradient);_x000D_
}

<svg width="100" height="50" version="1.1" xmlns="http://www.w3.org/2000/svg">_x000D_
      <style type="text/css">_x000D_
        rect{fill:url(#MyGradient)}_x000D_
      </style>_x000D_
      <defs>_x000D_
        <linearGradient id="MyGradient">_x000D_
          <stop offset="5%" stop-color="#F60" />_x000D_
          <stop offset="95%" stop-color="#FF6" />_x000D_
        </linearGradient>_x000D_
      </defs>_x000D_
      _x000D_
      <rect width="100" height="50"/>_x000D_
    </svg>

Internally, getters and setters are just methods. When C# compiles, it generates methods for your getters and setters like this, for example:

public int get_MyProperty() { ... }
public void set_MyProperty(int value) { ... }

C# allows you to declare these methods using a short-hand syntax. The line below will be compiled into the methods above when you build your application.

public int MyProperty { get; set; }

or

private int myProperty;
public int MyProperty 
{ 
    get { return myProperty; }
    set { myProperty = value; } // value is an implicit parameter containing the value being assigned to the property.
}

Well, .html() uses .innerHTML which is faster than DOM creation.

Ajax (also AJAX) an acronym for Asynchronous JavaScript and XML) is a group of interrelated web development techniques used on the client-side to create asynchronous web applications. With Ajax, web applications can send data to, and retrieve data from, a server asynchronously Below is example code:

Jsp page java script function to submit data to servlet with two variable firstName and lastName:

function onChangeSubmitCallWebServiceAJAX()
    {
      createXmlHttpRequest();
      var firstName=document.getElementById("firstName").value;
      var lastName=document.getElementById("lastName").value;
      xmlHttp.open("GET","/AJAXServletCallSample/AjaxServlet?firstName="
      +firstName+"&lastName="+lastName,true)
      xmlHttp.onreadystatechange=handleStateChange;
      xmlHttp.send(null);

    }

Servlet to read data send back to jsp in xml format ( You could use text as well. Just you need to change response content to text and render data on javascript function.)

/**
 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
 */
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    String firstName = request.getParameter("firstName");
    String lastName = request.getParameter("lastName");

    response.setContentType("text/xml");
    response.setHeader("Cache-Control", "no-cache");
    response.getWriter().write("<details>");
    response.getWriter().write("<firstName>"+firstName+"</firstName>");
    response.getWriter().write("<lastName>"+lastName+"</lastName>");
    response.getWriter().write("</details>");
}

In addressing your comment that you need your current time, and not the system time, you will have to make an adjustment yourself, there are 3600 seconds in an hour (the unit timestamps use), so use that. for example, if your system time was one hour behind:

$time = date('H:i',time() + 3600);

If you install MySQL via homebrew on MacOS, you might need to delete your old data directory /usr/local/var/mysql. Otherwise, it will fail during the initialization process with the following error:

You will need to define "special characters", but it's likely that for some string s you mean:

import re
if re.match(r'^\w+$', s):
    # s is good-to-go

it works fine without nine-patch Api 10+

Use the MultiValueDict's get method. This is also present on standard dicts and is a way to fetch a value while providing a default if it does not exist.

is_private = request.POST.get('is_private', False)

Generally,

my_var = dict.get(<key>, <default>)

A faster way is to join the list, replace 8 and split the new string:

mylist = [("aaaa8"),("bb8"),("ccc8"),("dddddd8")]
mylist = ' '.join(mylist).replace('8','').split()
print mylist

list(cursor) works because a cursor is an iterable; you can also use cursor in a loop:

for row in cursor:
    # ...

A good database adapter implementation will fetch rows in batches from the server, saving on the memory footprint required as it will not need to hold the full result set in memory. cursor.fetchall() has to return the full list instead.

There is little point in using list(cursor) over cursor.fetchall(); the end effect is then indeed the same, but you wasted an opportunity to stream results instead.

You could add a Category partial and a Product partial, each would take a smaller part of the main model as it's own model, i.e. Category's model type might be an IEnumerable, you would pass in Model.Theme to it. The Product's partial might be an IEnumerable that you pass Model.Products into (from within the Category partial).

I'm not sure if that would be the right way forward, but would be interested in knowing.

EDIT

Since posting this answer, I've used EditorTemplates and find this the easiest way to handle repeating input groups or items. It handles all your validation message problems and form submission/model binding woes automatically.

The lock screen works without keyguard i have tested it. The home button stops working and you can't get to task manager by holding the home key. I wish they didn't develop a new process when it used to be built into system ui or whatever. I don't see the need for the change and extra process

Since swift 3.0 there is more convenient way: #imageLiterals here is text example. And below animated example from here:

Even this will work nicely

REPT(0,2-LEN(F2)&F2

where 2 is total number of digits, for 0 ~ 9 -> it will display 00 to 09 rest nothing will be added.

I had exactly same problem, my solution was to

scp -i /path/pem -r /path/file/ ec2-user@public aws dns name: (leave it blank here)

once you done this part, get into ssh server and mv file to desired location

In my case i was missing trailing / in path.

find /var/opt/gitlab/backups/ -name *.tar
