You can't, because IEnumerable doesn't have an index at all... if you are sure your enumerable has less than int.MaxValue elements (or long.MaxValue if you use a long index), you can:

1. Don't use foreach, and use a for loop, converting your IEnumerable to a generic enumerable first:

   var genericList = list.Cast<object>();
   for(int i = 0; i < genericList.Count(); ++i)
   {
      var row = genericList.ElementAt(i);
      /* .... */
   }
   

2. Have an external index:

   int i = 0;
   foreach(var row in list)
   {
      /* .... */
      ++i;
   }
   

3. Get the index via Linq:

   foreach(var rowObject in list.Cast<object>().Select((r, i) => new {Row=r, Index=i}))
   {
     var row = rowObject.Row;
     var i = rowObject.Index;
     /* .... */    
   }
   

In your case, since your IEnumerable is not a generic one, I'd rather use the foreach with external index (second method)... otherwise, you may want to make the Cast<object> outside your loop to convert it to an IEnumerable<object>.

Your datatype is not clear from the question, but I'm assuming object since it's an items source (it could be DataGridRow)... you may want to check if it's directly convertible to a generic IEnumerable<object> without having to call Cast<object>(), but I'll make no such assumptions.

All this said:

The concept of an "index" is foreign to an IEnumerable. An IEnumerable can be potentially infinite. In your example, you are using the ItemsSource of a DataGrid, so more likely your IEnumerable is just a list of objects (or DataRows), with a finite (and hopefully less than int.MaxValue) number of members, but IEnumerable can represent anything that can be enumerated (and an enumeration can potentially never end).

Take this example:

public static IEnumerable InfiniteEnumerable()
{
  var rnd = new Random();
  while(true)
  {
    yield return rnd.Next();
  }
}

So if you do:

foreach(var row in InfiniteEnumerable())
{
  /* ... */
}

Your foreach will be infinite: if you used an int (or long) index, you'll eventually overflow it (and unless you use an unchecked context, it'll throw an exception if you keep adding to it: even if you used unchecked, the index would be meaningless also... at some point -when it overflows- the index will be the same for two different values).

So, while the examples given work for a typical usage, I'd rather not use an index at all if you can avoid it.

SelectedItem is an object. SelectedValue and SelectedValuePath are strings.

for example using the ListBox:

if you say give me listbox1.SelectedValue it will return the text of the currently selected item.

string value = listbox1.SelectedValue;

if you say give me listbox1.SelectedItem it will give you the entire object.

ListItem item = listbox1.SelectedItem;
string value = item.value;

I have a slightly simplified answer for this (with just the PreviewMouseLeftButtonDown event) which seems to mimic the usual functionality of a browser:

In XAML you have a TextBox say:

<TextBox Text="http://www.blabla.com" BorderThickness="2" BorderBrush="Green" VerticalAlignment="Center" Height="25"
                 PreviewMouseLeftButtonDown="SelectAll" />

In codebehind:

private void SelectAll(object sender, MouseButtonEventArgs e)
{
    TextBox tb = (sender as TextBox);

    if (tb == null)
    {
        return;
    }

    if (!tb.IsKeyboardFocusWithin)
    {
        tb.SelectAll();
        e.Handled = true;
        tb.Focus();
    }
}

In SL5 I found this to work:

<TextBlock Name="textBlock" Text="{Binding JustificationDate, StringFormat=dd-MMMM-yy hh:mm}">
<TextBlock Name="textBlock" Text="{Binding JustificationDate, StringFormat='Justification Date: \{0:dd-MMMM-yy hh:mm\}'}">

Seems to me like you want to create a property.

public int MyProperty
{
    get { return _myProperty; }
    set
    {
        _myProperty = value;
        if (_myProperty == 1)
        {
            // DO SOMETHING HERE
        }
    }
}

private int _myProperty;

This allows you to run some code any time the property value changes. You could raise an event here, if you wanted.

Grid.ColumnSpacing, Grid.RowSpacing, StackPanel.Spacing are now on UWP preview, all will allow to better acomplish what is requested here.

These properties are currently only available with the Windows 10 Fall Creators Update Insider SDK, but should make it to the final bits!

myImg.Source = new BitmapImage(new Uri(@"component/Images/down.png", UriKind.RelativeOrAbsolute)); 

Don't forget to set Build Action to "Content", and Copy to output directory to "Always".

This might be due to the fact that you are trying to add a ListBoxItem with a same name to the page.

If you want to refresh the content of the listbox with the newly retrieved values you will have to first manually remove the content of the listbox other wise your loop will try to create lb_1 again and add it to the same list.

Look at here for a similar problem that occured Silverlight: Value does not fall within the expected range exception

Cheers,

You may need to add a using statement to the file. The default Silverlight class template doesn't include it:

using System.Linq;

For me the solution was besides using "Ntlm" as credential type, similar as Jeroen K's solution. If I had the permission level I would plus on his post, but let me post my whole code here, which will support both Windows and other credential types like basic auth:

    XxxSoapClient xxxClient = new XxxSoapClient();
    ApplyCredentials(userName, password, xxxClient.ClientCredentials);

    private static void ApplyCredentials(string userName, string password, ClientCredentials clientCredentials)
    {
        clientCredentials.UserName.UserName = userName;
        clientCredentials.UserName.Password = password;
        clientCredentials.Windows.ClientCredential.UserName = userName;
        clientCredentials.Windows.ClientCredential.Password = password;
        clientCredentials.Windows.AllowNtlm = true;
        clientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;
    }  

I feel it is worth adding that a static variable is not the same as a constant variable.

using a constant variable in a class

struct Foo{
    const int a;
    Foo(int b) : a(b){}
}

and we would declare it like like so

fooA = new Foo(5);
fooB = new Foo(10);
// fooA.a = 5;
// fooB.a = 10;

For a static variable

struct Bar{
    static int a;
    Foo(int b){
        a = b;
    }
}
Bar::a = 0; // set value for a

which is used like so

barA = new Bar(5);
barB = new Bar(10);
// barA.a = 10;
// barB.a = 10;
// Bar::a = 10;

You see what happens here. The constant variable, which is instanced along with each instance of Foo, as Foo is instanced has a separate value for each instance of Foo, and it can't be changed by Foo at all.

Where as with Bar, their is only one value for Bar::a no matter how many instances of Bar are made. They all share this value, you can also access it with their being any instances of Bar. The static variable also abides rules for public/private, so you could make it that only instances of Bar can read the value of Bar::a;

use

window.location.replace("login.php");

or simply window.location("login.php");

It is better than using window.location.href =, because replace() does not put the originating page in the session history, meaning the user won't get stuck in a never-ending back-button fiasco. If you want to simulate someone clicking on a link, use location.href. If you want to simulate an HTTP redirect, use location.replace.

Here is my code of custom UITableView subclass, which expand UITextView at the table cell, without reloading (and lost keyboard focus):

- (void)textViewDidChange:(UITextView *)textView {
    CGFloat textHeight = [textView sizeThatFits:CGSizeMake(self.width, MAXFLOAT)].height;
    // Check, if text height changed
    if (self.previousTextHeight != textHeight && self.previousTextHeight > 0) {
        [self beginUpdates];

        // Calculate difference in height
        CGFloat difference = textHeight - self.previousTextHeight;

        // Update currently editing cell's height
        CGRect editingCellFrame = self.editingCell.frame;
        editingCellFrame.size.height += difference;
        self.editingCell.frame = editingCellFrame;

        // Update UITableView contentSize
        self.contentSize = CGSizeMake(self.contentSize.width, self.contentSize.height + difference);

        // Scroll to bottom if cell is at the end of the table
        if (self.editingNoteInEndOfTable) {
            self.contentOffset = CGPointMake(self.contentOffset.x, self.contentOffset.y + difference);
        } else {
            // Update all next to editing cells
            NSInteger editingCellIndex = [self.visibleCells indexOfObject:self.editingCell];
            for (NSInteger i = editingCellIndex; i < self.visibleCells.count; i++) {
                UITableViewCell *cell = self.visibleCells[i];
                CGRect cellFrame = cell.frame;
                cellFrame.origin.y += difference;
                cell.frame = cellFrame;
            }
        }
        [self endUpdates];
    }
    self.previousTextHeight = textHeight;
}

I ended up using:

Function DirectoryExists(Directory As String) As Boolean
    DirectoryExists = False
    If Len(Dir(Directory, vbDirectory)) > 0 Then
        If (GetAttr(Directory) And vbDirectory) = vbDirectory Then
            DirectoryExists = True
        End If
    End If
End Function

which is a mix of @Brian and @ZygD answers. Where I think @Brian's answer is not enough and don't like the On Error Resume Next used in @ZygD's answer

char cString1[]

This is an array, i.e. a pointer to the first element of a range of elements of the same data type. Note you're not passing the array by-value but by-pointer.

char strToLower(...)

However, this returns a char. So your assignment

cString1 = strToLower(cString1);

has different types on each side of the assignment operator .. you're actually assigning a 'char' (sort of integer) to an array, which resolves to a simple pointer. Due to C++'s implicit conversion rules this works, but the result is rubbish and further access to the array causes undefined behaviour.

The solution is to make strToLower return char*.

int elem = 42;
std::vector<int> v;
v.push_back(elem);
if(std::find(v.begin(), v.end(), elem) != v.end())
{
  //elem exists in the vector
} 

this should be close!

public static void OpenWithDefaultProgram(string path)
{
    Process fileopener = new Process();
    fileopener.StartInfo.FileName = "explorer";
    fileopener.StartInfo.Arguments = "\"" + path + "\"";
    fileopener.Start();
}

For EF Core migrationBuilder.RenameColumn usually works fine but sometimes you have to handle indexes as well.

migrationBuilder.RenameColumn(name: "Identifier", table: "Questions", newName: "ChangedIdentifier", schema: "dbo");

Example error message when updating database:

Microsoft.Data.SqlClient.SqlException (0x80131904): The index 'IX_Questions_Identifier' is dependent on column 'Identifier'.

The index 'IX_Questions_Identifier' is dependent on column 'Identifier'.

RENAME COLUMN Identifier failed because one or more objects access this column.

In this case you have to do the rename like this:

migrationBuilder.DropIndex(
    name: "IX_Questions_Identifier",
    table: "Questions");

migrationBuilder.RenameColumn(name: "Identifier", table: "Questions", newName: "ChangedIdentifier", schema: "dbo");

migrationBuilder.CreateIndex(
    name: "IX_Questions_ChangedIdentifier",
    table: "Questions",
    column: "ChangedIdentifier",
    unique: true,
    filter: "[ChangedIdentifier] IS NOT NULL");

There are many ways to fix this, like enabling automatic signing etc. But if you want to understand the reason for this error you need to look at the error message.

It says that the provisioning profile you have selected in the "General tab", does not contain the signing certificate you selected in the "Build settings" -> "Code Signing Identity".

Usually this happens if a distribution certificate has been selected for the debug identity under "Build settings" -> "Code Signing Identity".

If this happens under "Signing (Debug)" it might also be that the "Signing Identity" -> "iOS Development" is not included in the provisioning profile.

If i is the int, then

char c = i;

makes it a char. You might want to add a check that the value is <128 if it comes from an untrusted source. This is best done with isascii from <ctype.h>, if available on your system (see @Steve Jessop's comment to this answer).

You have to tell your SQLCommand objects to use the transaction:

cmd1.Transaction = transaction;

or in the constructor:

SqlCommand cmd1 = new SqlCommand("select...", connectionsql, transaction);

Make sure to have the connectionsql object open, too.

But all you are doing are SELECT statements. Transactions would benefit more when you use INSERT, UPDATE, etc type actions.

If anyone wants to add an URL on a single marker which not require for loops, here is how it goes:

if ($('#googleMap').length) {
    var initialize = function() {
        var mapOptions = {
            zoom: 15,
            scrollwheel: false,
            center: new google.maps.LatLng(45.725788, -73.5120818),
            styles: [{
                stylers: [{
                    saturation: -100
                }]
            }]
        };
        var map = new google.maps.Map(document.getElementById("googleMap"), mapOptions);
        var marker = new google.maps.Marker({
            position: map.getCenter(),
            animation: google.maps.Animation.BOUNCE,
            icon: 'example-marker.png',
            map: map,
            url: 'https://example.com'
        });

        //Add an url to the marker
    google.maps.event.addListener(marker, 'click', function() {
        window.location.href = this.url;
    });
    }
    // Add the map initialize function to the window load function
    google.maps.event.addDomListener(window, "load", initialize);
}

Does not seem like it, but android recognises a webcam as a device. Every time I run the emulator my webcam's active light comes on.

I assume you're using GCC. The standard solution would be to profile with gprof.

Be sure to add -pg to compilation before profiling:

cc -o myprog myprog.c utils.c -g -pg

I haven't tried it yet but I've heard good things about google-perftools. It is definitely worth a try.

Related question here.

A few other buzzwords if gprof does not do the job for you: Valgrind, Intel VTune, Sun DTrace.

• Ensure debug mode is on - either add APP_DEBUG=true to .env file or set an environment variable

• Log files are in storage/logs folder. laravel.log is the default filename. If there is a permission issue with the log folder, Laravel just halts. So if your endpoint generally works - permissions are not an issue.

• In case your calls don't even reach Laravel or aren't caused by code issues - check web server's log files (check your Apache/nginx config files to see the paths).

• If you use PHP-FPM, check its log files as well (you can see the path to log file in PHP-FPM pool config).

The response of staff is correct, but if you want to further automate can do:

$ sudo -u postgres psql -c "ALTER USER postgres PASSWORD 'postgres';"

Done! You saved User = postgres and password = postgres.

If you do not have a password for the User postgres ubuntu do:

$ sudo passwd postgres

As of version 18.03, you can use host.docker.internal as the host's IP.

Works in Docker for Mac, Docker for Windows, and perhaps other platforms as well.

This is an update from the Mac-specific docker.for.mac.localhost, available since version 17.06, and docker.for.mac.host.internal, available since version 17.12, which may also still work on that platform.

Note, as in the Mac and Windows documentation, this is for development purposes only.

For example, I have environment variables set on my host:

MONGO_SERVER=host.docker.internal

In my docker-compose.yml file, I have this:

version: '3'

services:
  api:
    build: ./api
    volumes:
      - ./api:/usr/src/app:ro
    ports:
      - "8000"
    environment:
      - MONGO_SERVER
    command: /usr/local/bin/gunicorn -c /usr/src/app/gunicorn_config.py -w 1 -b :8000 wsgi

for (int i = 0; i < a.length; i++) {
    for (int k = 0; k < a.length; k++) {
        if (a[i] != a[k]) {
            System.out.println(a[i] + " not the same with  " + a[k + 1] + "\n");
        }
    }
}

You can start from k=1 & keep "a.length-1" in outer for loop, in order to reduce two comparisions,but that doesnt make any significant difference.

Why PendingIntent is required ? I was thinking like

1. Why the receiving application itself cannot create the Intent or
2. Why we cannot use a simple Intent for the same purpose.

E.g.Intent bluetoothIntent= new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);

If I send bluetoothIntent to another application, which doesn't have permission android.permission.BLUETOOTH_ADMIN, that receiving application cannot enable Bluetooth with startActivity(bluetoothIntent).

The limitation is overcome using PendingIntent. With PendingIntent the receiving application, doesn't need to have android.permission.BLUETOOTH_ADMIN for enabling Bluetooth. Source.

With n being the line number:

• ng: Jump to line number n. Default is the start of the file.
• nG: Jump to line number n. Default is the end of the file.

So to go to line number 320123, you would type 320123g.

Copy-pasted straight from Wikipedia.

You can use the sequence method list.extend to extend the list by multiple values from any kind of iterable, being it another list or any other thing that provides a sequence of values.

>>> lst = [1, 2]
>>> lst.append(3)
>>> lst.append(4)
>>> lst
[1, 2, 3, 4]

>>> lst.extend([5, 6, 7])
>>> lst.extend((8, 9, 10))
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

>>> lst.extend(range(11, 14))
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]

So you can use list.append() to append a single value, and list.extend() to append multiple values.

And if all else fails, such as ensuring that the target frameworks are the same, and you are dealing with a WPF class library in VS2010, simply restart Visual Studio. That did it for me.

I was getting the issue 'Newtonsoft.Json' already has a dependency defined for 'Microsoft.CSharp' on the TeamCity build server. I changed the "Update Mode" of the Nuget Installer build step from solution file to packages.config and NuGet.exe to the latest version (I had 3.5.0) and it worked !!

I came here looking for a solution for extended ascii characters, but couldnt find it. The closest I found is bzlm's solution. But that works only for ASCII Code upto 127(obviously you can replace the encoding type in his code, but i think it was a bit complex to understand. Hence, sharing this version). Here's a solution that works for extended ASCII codes i.e. upto 255 which is the ISO 8859-1

It finds and strips out non-ascii characters(greater than 255)

Dim str1 as String= "â, ??î or ôu? n?i?++$-?!??4?od;/?'®;?:?)///1!@#"

Dim extendedAscii As Encoding = Encoding.GetEncoding("ISO-8859-1", 
                                                New EncoderReplacementFallback(String.empty),
                                                New DecoderReplacementFallback())

Dim extendedAsciiBytes() As Byte = extendedAscii.GetBytes(str1)

Dim str2 As String = extendedAscii.GetString(extendedAsciiBytes)

console.WriteLine(str2)
'Output : â, ??î or ôu ni++$-!??4od;/';:)///1!@#$%^yz:

Here's a working fiddle for the code

Replace the encoding as per the requirement, rest should remain the same.

Note: it is invalid to provide percentages directly as <img> width or height attribute unless you're using HTML 4.01 (see current spec, obsolete spec and this answer for more details). That being said, browsers will often tolerate such behaviour to support backwards-compatibility.

Those percentage widths in your 2nd example are actually applying to the container your <img> is in, and not the image's actual size. Say you have the following markup:

<div style="width: 1000px; height: 600px;">
    <img src="#" width="50%" height="50%">
</div>

Your resulting image will be 500px wide and 300px tall.

jQuery Resize

If you're trying to reduce an image to 50% of its width, you can do it with a snippet of jQuery:

$( "img" ).each( function() {
    var $img = $( this );
    $img.width( $img.width() * .5 );
});

Just make sure you take off any height/width = 50% attributes first.

Depending on your application, you may want to consider using System.nanoTime() instead.

Here's the whole code snippet needed:

$queried_object = get_queried_object();
$term_id = $queried_object->term_id;

Try that:

  var defaultEmailNews = "Email address";
  $('input[name=email]').focus(function() {
    if($(this).val() == defaultEmailNews) $(this).val("");
  });

  $('input[name=email]').focusout(function() {
    if($(this).val() == "") $(this).val(defaultEmailNews);
  });

This might be considered one of the options. now if you wanted to load a yml file ( which did not get loaded by default on applying the above annotations) the trick is to use

@ContextConfiguration(classes= {...}, initializers={ConfigFileApplicationContextInitializer.class})

Here is a sample code

@RunWith(SpringRunner.class)
@ActiveProfiles("test")
@DirtiesContext
@ContextConfiguration(classes= {DataSourceTestConfig.class}, initializers = {ConfigFileApplicationContextInitializer.class})
public class CustomDateDeserializerTest {


    private ObjectMapper objMapper;

    @Before
    public void setUp() {
        objMapper = new ObjectMapper();

    }

    @Test
    public void test_dateDeserialization() {

    }
}

Again make sure that the setup config java file - here DataSourceTestConfig.java contains the following property values.

@Configuration
@ActiveProfiles("test")
@TestPropertySource(properties = { "spring.config.location=classpath:application-test.yml" })
public class DataSourceTestConfig implements EnvironmentAware {

    private Environment env;

    @Bean
    @Profile("test")
    public DataSource testDs() {
       HikariDataSource ds = new HikariDataSource();

        boolean isAutoCommitEnabled = env.getProperty("spring.datasource.hikari.auto-commit") != null ? Boolean.parseBoolean(env.getProperty("spring.datasource.hikari.auto-commit")):false;
        ds.setAutoCommit(isAutoCommitEnabled);
        // Connection test query is for legacy connections
        //ds.setConnectionInitSql(env.getProperty("spring.datasource.hikari.connection-test-query"));
        ds.setPoolName(env.getProperty("spring.datasource.hikari.pool-name"));
        ds.setDriverClassName(env.getProperty("spring.datasource.driver-class-name"));
        long timeout = env.getProperty("spring.datasource.hikari.idleTimeout") != null ? Long.parseLong(env.getProperty("spring.datasource.hikari.idleTimeout")): 40000;
        ds.setIdleTimeout(timeout);
        long maxLifeTime = env.getProperty("spring.datasource.hikari.maxLifetime") != null ? Long.parseLong(env.getProperty("spring.datasource.hikari.maxLifetime")): 1800000 ;
        ds.setMaxLifetime(maxLifeTime);
        ds.setJdbcUrl(env.getProperty("spring.datasource.url"));
        ds.setPoolName(env.getProperty("spring.datasource.hikari.pool-name"));
        ds.setUsername(env.getProperty("spring.datasource.username"));
        ds.setPassword(env.getProperty("spring.datasource.password"));
        int poolSize = env.getProperty("spring.datasource.hikari.maximum-pool-size") != null ? Integer.parseInt(env.getProperty("spring.datasource.hikari.maximum-pool-size")): 10;
        ds.setMaximumPoolSize(poolSize);

        return ds;
    }

    @Bean
    @Profile("test")
    public JdbcTemplate testJdbctemplate() {
        return new JdbcTemplate(testDs());
    }

    @Bean
    @Profile("test")
    public NamedParameterJdbcTemplate testNamedTemplate() {
        return new NamedParameterJdbcTemplate(testDs());
    }

    @Override
    public void setEnvironment(Environment environment) {
        // TODO Auto-generated method stub
        this.env = environment;
    }
}

Initialize tSize to

tSize = ""  

before your if block to be safe. Also in your else case, put tSize in quotes so it is a string not an int. Also also you are comparing strings to ints.

Here's my ultimate answer to this.

Also apparently javascript's new Date(year, month, day) constructor doesn't account for leap seconds too.

// Parses an Excel Date ("serial") into a
// corresponding javascript Date in UTC+0 timezone.
//
// Doesn't account for leap seconds.
// Therefore is not 100% correct.
// But will do, I guess, since we're
// not doing rocket science here.
//
// https://www.pcworld.com/article/3063622/software/mastering-excel-date-time-serial-numbers-networkdays-datevalue-and-more.html
// "If you need to calculate dates in your spreadsheets,
//  Excel uses its own unique system, which it calls Serial Numbers".
//
lib.parseExcelDate = function (excelSerialDate) {
  // "Excel serial date" is just
  // the count of days since `01/01/1900`
  // (seems that it may be even fractional).
  //
  // The count of days elapsed
  // since `01/01/1900` (Excel epoch)
  // till `01/01/1970` (Unix epoch).
  // Accounts for leap years
  // (19 of them, yielding 19 extra days).
  const daysBeforeUnixEpoch = 70 * 365 + 19;

  // An hour, approximately, because a minute
  // may be longer than 60 seconds, see "leap seconds".
  const hour = 60 * 60 * 1000;

  // "In the 1900 system, the serial number 1 represents January 1, 1900, 12:00:00 a.m.
  //  while the number 0 represents the fictitious date January 0, 1900".
  // These extra 12 hours are a hack to make things
  // a little bit less weird when rendering parsed dates.
  // E.g. if a date `Jan 1st, 2017` gets parsed as
  // `Jan 1st, 2017, 00:00 UTC` then when displayed in the US
  // it would show up as `Dec 31st, 2016, 19:00 UTC-05` (Austin, Texas).
  // That would be weird for a website user.
  // Therefore this extra 12-hour padding is added
  // to compensate for the most weird cases like this
  // (doesn't solve all of them, but most of them).
  // And if you ask what about -12/+12 border then
  // the answer is people there are already accustomed
  // to the weird time behaviour when their neighbours
  // may have completely different date than they do.
  //
  // `Math.round()` rounds all time fractions
  // smaller than a millisecond (e.g. nanoseconds)
  // but it's unlikely that an Excel serial date
  // is gonna contain even seconds.
  //
  return new Date(Math.round((excelSerialDate - daysBeforeUnixEpoch) * 24 * hour) + 12 * hour);
};

Other than mentioned answers..I would like to add some other points.

Bias acts as our anchor. It's a way for us to have some kind of baseline where we don't go below that. In terms of a graph, think of like y=mx+b it's like a y-intercept of this function.

output = input times the weight value and added a bias value and then apply an activation function.

From Python Cookbook v.30

def myfun():
    return 1, 2, 3

a, b, c = myfun()

Although it looks like myfun() returns multiple values, a tuple is actually being created. It looks a bit peculiar, but it’s actually the comma that forms a tuple, not the parentheses

So yes, what's going on in Python is an internal transformation from multiple comma separated values to a tuple and vice-versa.

Though there's no equivalent in java you can easily create this behaviour using array's or some Collections like Lists:

private static int[] sumAndRest(int x, int y) {
    int[] toReturn = new int[2];

    toReturn[0] = x + y;
    toReturn[1] = x - y;

    return toReturn;

}

Executed in this way:

public static void main(String[] args) {
    int[] results = sumAndRest(10, 5);

    int sum  = results[0];
    int rest = results[1];

    System.out.println("sum = " + sum + "\nrest = " + rest);

}

result:

sum = 15
rest = 5

Sum of arithmetical progression

(A1+AN)/2*N = (1 + (N-1))/2*(N-1) = N*(N-1)/2

There are various methods for collision resolution.Some of them are Separate Chaining,Open addressing,Robin Hood hashing,Cuckoo Hashing etc.

Java uses Separate Chaining for resolving collisions in Hash tables.Here is a great link to how it happens: http://javapapers.com/core-java/java-hashtable/

Another vote for Valgrind here, but I would like to add that you can use a tool like Alleyoop to help you interpret the results generated by Valgrind.

I use the two tools all the time and always have lean, non-leaky code to proudly show for it ;)

You have to reference System.Configuration via explorer (not only append using System.Configuration). Then you can write:

string xmlDataDirectory = 
    System.Configuration.ConfigurationManager.AppSettings.Get("xmlDataDirectory");

Tested with VS2010 (thanks to www.developpez.net). Hope this helps.

Let's say you have added a file "xyz.js" under assets/js folder in some Angular project in Visual-Studio, then the easiest way to include that file is to add it to .angular-cli.json

"scripts": [ "assets/js/xyz.js" ],

You should be able to use this JS file's functionality in your component or .ts files.

Use html2text (example HTML to text), licensed under the Eclipse Public License. It uses PHP's DOM methods to load from HTML, and then iterates over the resulting DOM to extract plain text. Usage:

// when installed using the Composer package
$text = Html2Text\Html2Text::convert($html);

// usage when installed using html2text.php
require('html2text.php');
$text = convert_html_to_text($html);

Although incomplete, it is open source and contributions are welcome.

Issues with other conversion scripts:

• Since html2text (GPL) is not EPL-compatible.
• lkessler's link (attribution) is incompatible with most open source licenses.

This works good

Server 2008:

When in SSMS connected to server1.DB1 and try:

SELECT  * FROM
[server2].[DB2].[dbo].[table1]

as others noted, if it doesn't work it's because the server isn't linked.

I get the error:

Could not find server DB2 in sys.servers. Verify that the correct server name was specified. If necessary, execute stored procedure sp_addlinkedserver to add the server to sys.servers.

To add the server:

reference: To add server using sp_addlinkedserver Link: [1]: To add server using sp_addlinkedserver

To see what is in your sys.servers just query it:

SELECT * FROM [sys].[servers]

The "nav nav-list" class of Twiter Bootstrap 2.0 is handy for building a side bar.

You can see a lot of documentation at http://www.w3resource.com/twitter-bootstrap/nav-tabs-and-pills-tutorial.php

The following works for me:

$('video')[0].pause();

The most direct way to get a list of columns of certain dtype e.g. 'object':

df.select_dtypes(include='object').columns

For example:

>>df = pd.DataFrame([[1, 2.3456, 'c', 'd', 78]], columns=list("ABCDE"))
>>df.dtypes

A      int64
B    float64
C     object
D     object
E      int64
dtype: object

To get all 'object' dtype columns:

>>df.select_dtypes(include='object').columns

Index(['C', 'D'], dtype='object')

For just the list:

>>list(df.select_dtypes(include='object').columns)

['C', 'D']   

Strings are immutable and cannot be altered once they have been created. Creating a password as a string will leave stray references to the password on the heap or on the String pool. Now if someone takes a heap dump of the Java process and carefully scans through he might be able to guess the passwords. Of course these non used strings will be garbage collected but that depends on when the GC kicks in.

On the other side char[] are mutable as soon as the authentication is done you can overwrite them with any character like all M's or backslashes. Now even if someone takes a heap dump he might not be able to get the passwords which are not currently in use. This gives you more control in the sense like clearing the Object content yourself vs waiting for the GC to do it.

Try this:

driver.manage().window().maximize();

in some case you can use annotation @Primary.

@Primary
class USA implements Country {}

This way it will be selected as the default autowire candididate, with no need to autowire-candidate on the other bean.

for mo deatils look at Autowiring two beans implementing same interface - how to set default bean to autowire?

Ensure that the permissions on your home directory and on the home directory of the user on the host you're connecting to are set to 700 ( owning user rwx only to prevent others seeing the .ssh subdirectory ).

Then ensure that the ~/.ssh directory is also 700 ( user rwx ) and that the authorized_keys is 600 ( user rw ) .

Private keys in your ~/.ssh directory should be 600 or 400 ( user rw or user r )

The WHERE clause is always conceptually applied (the execution plan can do what it wants, obviously) prior to the GROUP BY. It must come before the GROUP BY in the query, and acts as a filter before things are SUMmed, which is how most of the answers here work.

You should also be aware of the optional HAVING clause which must come after the GROUP BY. This can be used to filter on the resulting properties of groups after GROUPing - for instance HAVING SUM(Amount) > 0

Local classes have already been mentioned, but here is a way to let them appear even more as local functions, using an operator() overload and an anonymous class:

int main() {
    struct {
        unsigned int operator() (unsigned int val) const {
            return val<=1 ? 1 : val*(*this)(val-1);
        }
    } fac;

    std::cout << fac(5) << '\n';
}

I don't advise on using this, it's just a funny trick (can do, but imho shouldn't).

2014 Update:

With the rise of C++11 a while back, you can now have local functions whose syntax is a little reminiscient of JavaScript:

auto fac = [] (unsigned int val) {
    return val*42;
};

Sounds like you probably want a simple method like this:

public String getValueOrDefault(String value, String defaultValue) {
    return isNotNullOrEmpty(value) ? value : defaultValue;
}

Then:

String result = getValueOrDefault(System.getProperty("XYZ"), "default");

At this point, you don't need temp... you've effectively used the method parameter as a way of initializing the temporary variable.

If you really want temp and you don't want an extra method, you can do it in one statement, but I really wouldn't:

public class Test {
    public static void main(String[] args) {
        String temp, result = isNotNullOrEmpty(temp = System.getProperty("XYZ")) ? temp : "default";
        System.out.println("result: " + result);
        System.out.println("temp: " + temp);
    }

    private static boolean isNotNullOrEmpty(String str) {
        return str != null && !str.isEmpty();
    }
}

What's abaut this one:

List<int> tmpList = intArry.ToList(); tmpList.Add(anyInt); intArry = tmpList.ToArray();

I had the same problem and fixed it with this command:

$ git push -u origin master

From the help file the -u basically sets the default for pulls:

-u, --set-upstream`

  For every branch that is up to date or successfully pushed, add 
  upstream (tracking) reference, used by argument-less git-pull(1) and
  other commands. For more information, see branch.<name>.merge in 
  git-config(1).

Since 2019, Google Firebase has a big change in their APIs I mean: 'com.google.firebase:firebase-messaging:18.0.0'

in 18.0.0 they removed MyFirebaseInstanceIDService and you need to get token in MyFirebaseMessagingService so you just need to write :

@Override
public void onNewToken(String token) {
    Log.d(TAG, "Refreshed token: " + token);

}

and also in your AndroidManifest.xml, you have to remove :

<service android:name=".service.MyFirebaseInstanceIDService">
        <intent-filter>
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
        </intent-filter>
    </service>

Also, you're recommended to set default values to customize the appearance of notifications. You can specify a custom default icon and a custom default color that are applied whenever equivalent values are not set in the notification payload.

Add these lines inside the application tag to set the custom default icon and custom color:

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_icon"
        android:resource="@drawable/ic_notification" />

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_color"
        android:resource="@color/colorAccent" />

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_channel_id"
        android:value="@string/push_channel" />

now to handle notification messages in a backgrounded app you should define an Intent in your first Activity even if it is SplashScreen, When your app is in the background, Android directs notification messages to the system tray. A user tap on the notification opens the app launcher by default.

for example, if your Json is like this:

 "data": {
"message": "2",
"title": "1",
"pushType" : "banner",
"bannerLink": "http://www.google.com",
"image" : "https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png"}

you just need to write a simple intent to get those values:

        Bundle extras = intent.getExtras();
        String bannerLink = extras.getString("bannerLink");
        ...
        String channelId = extras.getString("channelId");

you have an type error in example of code. You forget curlybracket after success

$.ajax({
 type: "POST",
 url: '@Url.Action("Search","Controller")',
 data: "{queryString:'" + searchVal + "'}",
 contentType: "application/json; charset=utf-8",
 dataType: "html",
 success: function (data) {
     alert("here" + data.d.toString());
 }
})

;

best way I know

         window.onbeforeunload = function (e) {
            var e = e || window.event;
            var msg = "Do you really want to leave this page?"

            // For IE and Firefox
            if (e) {
                e.returnValue = msg;
            }

            // For Safari / chrome
            return msg;
         };

No need to pass anything in. The function used for addEventListener will automatically have this bound to the current element. Simply use this in your function:

productLineSelect.addEventListener('change', getSelection, false);

function getSelection() {
    var value = this.options[this.selectedIndex].value;
    alert(value);
}

Here's the fiddle: http://jsfiddle.net/dJ4Wm/

If you want to pass arbitrary data to the function, wrap it in your own anonymous function call:

productLineSelect.addEventListener('change', function() {
    foo('bar');
}, false);

function foo(message) {
    alert(message);
}

Here's the fiddle: http://jsfiddle.net/t4Gun/

If you want to set the value of this manually, you can use the call method to call the function:

var self = this;
productLineSelect.addEventListener('change', function() {
    getSelection.call(self);
    // This'll set the `this` value inside of `getSelection` to `self`
}, false);

function getSelection() {
    var value = this.options[this.selectedIndex].value;
    alert(value);
}

Shorter:

   Split(stringval,":")(0)

Let me know if this is what you need. Or some thing is missing. I went through the other answers and found that jquery has been used . I took it on assumption that you need css solution . If I am missing any more point please mention :)

You can get a columns value by doing this

 rows["ColumnName"]

You will also have to cast to the appropriate type.

 output += (string)rows["ColumnName"]

Be sure you use com.fasterxml.jackson everywhere. I spent much time to find it out.

<properties>
  <fasterxml.jackson.version>2.9.2</fasterxml.jackson.version>
</properties>

<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-annotations -->
<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>${fasterxml.jackson.version}</version>
</dependency>

<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->
<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>${fasterxml.jackson.version}</version>
</dependency>

Then use @JsonManagedReference and @JsonBackReference.

Finally, you can serialize your model to JSON:

import com.fasterxml.jackson.databind.ObjectMapper;

ObjectMapper mapper = new ObjectMapper();
String json = mapper.writeValueAsString(model);

1. PSYoungGen refers to the garbage collector in use for the minor collection. PS stands for Parallel Scavenge.
2. The first set of numbers are the before/after sizes of the young generation and the second set are for the entire heap. (Diagnosing a Garbage Collection problem details the format)
3. The name indicates the generation and collector in question, the second set are for the entire heap.

An example of an associated full GC also shows the collectors used for the old and permanent generations:

3.757: [Full GC [PSYoungGen: 2672K->0K(35584K)] 
            [ParOldGen: 3225K->5735K(43712K)] 5898K->5735K(79296K) 
            [PSPermGen: 13533K->13516K(27584K)], 0.0860402 secs]

Finally, breaking down one line of your example log output:

8109.128: [GC [PSYoungGen: 109884K->14201K(139904K)] 691015K->595332K(1119040K), 0.0454530 secs]

• 107Mb used before GC, 14Mb used after GC, max young generation size 137Mb
• 675Mb heap used before GC, 581Mb heap used after GC, 1Gb max heap size
• minor GC occurred 8109.128 seconds since the start of the JVM and took 0.04 seconds

The $ operator is for avoiding parentheses. Anything appearing after it will take precedence over anything that comes before.

For example, let's say you've got a line that reads:

putStrLn (show (1 + 1))

If you want to get rid of those parentheses, any of the following lines would also do the same thing:

putStrLn (show $ 1 + 1)
putStrLn $ show (1 + 1)
putStrLn $ show $ 1 + 1

The primary purpose of the . operator is not to avoid parentheses, but to chain functions. It lets you tie the output of whatever appears on the right to the input of whatever appears on the left. This usually also results in fewer parentheses, but works differently.

Going back to the same example:

putStrLn (show (1 + 1))

1. (1 + 1) doesn't have an input, and therefore cannot be used with the . operator.
2. show can take an Int and return a String.
3. putStrLn can take a String and return an IO ().

You can chain show to putStrLn like this:

(putStrLn . show) (1 + 1)

If that's too many parentheses for your liking, get rid of them with the $ operator:

putStrLn . show $ 1 + 1

1. Create a new Java project in Eclipse. This will create a src folder (to contain your source files).

2. Also create a lib folder (the name isn't that important, but it follows standard conventions).

3. Copy the ./com/* folders into the /src folder (you can just do this using the OS, no need to do any fancy importing or anything from the Eclipse GUI).

4. Copy any dependencies (jar files that your project itself depends on) into /lib (note that this should NOT include the TGGL jar - thanks to commenter Mike Deck for pointing out my misinterpretation of the OPs post!)

5. Copy the other TGGL stuff into the root project folder (or some other folder dedicated to licenses that you need to distribute in your final app)

6. Back in Eclipse, select the project you created in step 1, then hit the F5 key (this refreshes Eclipse's view of the folder tree with the actual contents.

7. The content of the /src folder will get compiled automatically (with class files placed in the /bin file that Eclipse generated for you when you created the project). If you have dependencies (which you don't in your current project, but I'll include this here for completeness), the compile will fail initially because you are missing the dependency jar files from the project classpath.

8. Finally, open the /lib folder in Eclipse, right click on each required jar file and choose Build Path->Add to build path.

That will add that particular jar to the classpath for the project. Eclipse will detect the change and automatically compile the classes that failed earlier, and you should now have an Eclipse project with your app in it.

You can also use a callable in the default field, such as:

b = models.CharField(max_length=7, default=foo)

And then define the callable:

def foo():
    return 'bar'

I would recommend replace() rather than attach()/detach() in your tab handling.

Or, switch to ViewPager. Here is a sample project showing a ViewPager, with tabs, hosting 10 maps.

I got this error when I did a Response.Redirect after a successful login of the user.

I fixed it by doing a FormsAuthentication.RedirectFromLoginPage instead.

use "" with the string resource value.

Example :

<string>"value with spaces"</string>

OR

use \u0020 code for spaces.

If you want to see the array as an array, you can say

alert(JSON.stringify(aCustomers));

instead of all those document.writes.

However, if you want to display them cleanly, one per line, in your popup, do this:

alert(aCustomers.join("\n"));

What is the real difference between one-to-many and many-to-one relationship?

There are conceptual differences between these terms that should help you visualize the data and also possible differences in the generated schema that should be fully understood. Mostly the difference is one of perspective though.

In a one-to-many relationship, the local table has one row that may be associated with many rows in another table. In the example from SQL for beginners, one Customer may be associated to many Orders.

In the opposite many-to-one relationship, the local table may have many rows that are associated with one row in another table. In our example, many Orders may be associated to one Customer. This conceptual difference is important for mental representation.

In addition, the schema which supports the relationship may be represented differently in the Customer and Order tables. For example, if the customer has columns id and name:

id,name
1,Bill Smith
2,Jim Kenshaw

Then for a Order to be associated with a Customer, many SQL implementations add to the Order table a column which stores the id of the associated Customer (in this schema customer_id:

id,date,amount,customer_id
10,20160620,12.34,1
11,20160620,7.58,1
12,20160621,158.01,2

In the above data rows, if we look at the customer_id id column, we see that Bill Smith (customer-id #1) has 2 orders associated with him: one for $12.34 and one for $7.58. Jim Kenshaw (customer-id #2) has only 1 order for $158.01.

What is important to realize is that typically the one-to-many relationship doesn't actually add any columns to the table that is the "one". The Customer has no extra columns which describe the relationship with Order. In fact the Customer might also have a one-to-many relationship with ShippingAddress and SalesCall tables and yet have no additional columns added to the Customer table.

However, for a many-to-one relationship to be described, often an id column is added to the "many" table which is a foreign-key to the "one" table -- in this case a customer_id column is added to the Order. To associated order #10 for $12.34 to Bill Smith, we assign the customer_id column to Bill Smith's id 1.

However, it is also possible for there to be another table that describes the Customer and Order relationship, so that no additional fields need to be added to the Order table. Instead of adding a customer_id field to the Order table, there could be Customer_Order table that contains keys for both the Customer and Order.

customer_id,order_id
1,10
1,11
2,12

In this case, the one-to-many and many-to-one is all conceptual since there are no schema changes between them. Which mechanism depends on your schema and SQL implementation.

Hope this helps.

I believe that it is virtually never correct to use nolock.

If you are reading a single row, then the correct index means that you won't need NOLOCK as individual row actions are completed quickly.

If you are reading many rows for anything other than temporary display, and care about being able repeat the result, or defend by the number produced, then NOLOCK is not appropriate.

NOLOCK is a surrogate tag for "i don't care if this answer contains duplicate rows, rows which are deleted, or rows which were never inserted to begin with because of rollback"

Errors which are possible under NOLOCK:

• Rows which match are not returned at all.
• single rows are returned multiple times (including multiple instances of the same primary key)
• Rows which do not match are returned.

Any action which can cause a page split while the noLock select is running can cause these things to occur. Almost any action (even a delete) can cause a page split.

Therefore: if you "know" that the row won't be changed while you are running, don't use nolock, as an index will allow efficient retrieval.

If you suspect the row can change while the query is running, and you care about accuracy, don't use nolock.

If you are considering NOLOCK because of deadlocks, examine the query plan structure for unexpected table scans, trace the deadlocks and see why they occur. NOLOCK around writes can mean that queries which previously deadlocked will potentially both write the wrong answer.

If you are refering to res strings, use CDATA with \n.

Use the constructor for appending material to the file:

FileOutputStream(File file, boolean append)
Creates a file output stream to write to the file represented by the specified File object.

So to append to a file say "abc.txt" use

FileOutputStream fos=new FileOutputStream(new File("abc.txt"),true);

Here is how you can retrieve only directories with GLOB:

$directories = glob($somePath . '/*' , GLOB_ONLYDIR);

The problem is that you use a localizing formatter that generates locale-specific decimal point, which is "," in your case. But Double.parseDouble() expects non-localized double literal. You could solve your problem by using a locale-specific parsing method or by changing locale of your formatter to something that uses "." as the decimal point. Or even better, avoid unnecessary formatting by using something like this:

double rounded = (double) Math.round(value * 100.0) / 100.0;

use OTHER OPEN memorystream:

example for lauch pdf and send pdf in MVC4 C# Controller

        public void ToPdf(string uco, int idAudit)
    {
        Response.Clear();
        Response.ContentType = "application/octet-stream";
        Response.AddHeader("content-disposition", "attachment;filename= Document.pdf");
        Response.Buffer = true;
        Response.Clear();

        //get the memorystream pdf
        var bytes = new MisAuditoriasLogic().ToPdf(uco, idAudit).ToArray();

        Response.OutputStream.Write(bytes, 0, bytes.Length);
        Response.OutputStream.Flush();

    }


    public ActionResult ToMail(string uco, string filter, int? page, int idAudit, int? full) 
    {
        //get the memorystream pdf
        var bytes = new MisAuditoriasLogic().ToPdf(uco, idAudit).ToArray();

        using (var stream = new MemoryStream(bytes))
        using (var mailClient = new SmtpClient("**YOUR SERVER**", 25))
        using (var message = new MailMessage("**SENDER**", "**RECEIVER**", "Just testing", "See attachment..."))
        {

            stream.Position = 0;

            Attachment attach = new Attachment(stream, new System.Net.Mime.ContentType("application/pdf"));
            attach.ContentDisposition.FileName = "test.pdf";

            message.Attachments.Add(attach);

            mailClient.Send(message);
        }

        ViewBag.errMsg = "Documento enviado.";

        return Index(uco, filter, page, idAudit, full);
    }

Strict aliasing is not allowing different pointer types to the same data.

This article should help you understand the issue in full detail.

Try to check if the div has a class attribute first, like this:

soup = BeautifulSoup(sdata)
mydivs = soup.findAll('div')
for div in mydivs:
    if "class" in div:
        if (div["class"]=="stylelistrow"):
            print div

You can only do so during a transaction.

BEGIN;
INSERT INTO xxx ...;
DELETE FROM ...;

Then you can either:

COMMIT; -- will confirm your changes

Or

ROLLBACK -- will undo your previous changes

If you have a key that is repeated for each row, then you can produce a cartesian product using merge (like you would in SQL).

from pandas import DataFrame, merge
df1 = DataFrame({'key':[1,1], 'col1':[1,2],'col2':[3,4]})
df2 = DataFrame({'key':[1,1], 'col3':[5,6]})

merge(df1, df2,on='key')[['col1', 'col2', 'col3']]

Output:

   col1  col2  col3
0     1     3     5
1     1     3     6
2     2     4     5
3     2     4     6

See here for the documentation: http://pandas.pydata.org/pandas-docs/stable/merging.html#brief-primer-on-merge-methods-relational-algebra

I am using this vanilla js function to add "modal-open" class to the body. (Based on smhmic's answer)

function freezeScroll(show, new_width)
{
    var innerWidth = window.innerWidth,
        clientWidth = document.documentElement.clientWidth,
        new_margin = ((show) ? (new_width + innerWidth - clientWidth) : new_width) + "px";

    document.body.style.marginRight = new_margin;
    document.body.className = (show) ? "modal-open" : "";
};

Give this a try...

The dictionary is an object, not an array. I believe ng-repeat requires an array in Angular 2.

The simplest solution would be to create a pipe/filter that converts the object to an array on the fly. That said, you probably want to use an array as @basarat says.

If you'd like to use Code Behind, may I suggest the following solution for an asp:button -

ASPX Page

<asp:Button ID="btnRecover" runat="server" Text="Recover" OnClick="btnRecover_Click" />

Code Behind

    protected void btnRecover_Click(object sender, EventArgs e)
    {
        var recoveryId = Guid.Parse(lbRecovery.SelectedValue);
        var url = string.Format("{0}?RecoveryId={1}", @"../Recovery.aspx", vehicleId);

        // Response.Redirect(url); // Old way

        Response.Write("<script> window.open( '" + url + "','_blank' ); </script>");
        Response.End();
    }

if you are allowed to do it globally then you can set the session time out in

TOMCAT_HOME/conf/web.xml as below

 <!-- ==================== Default Session Configuration ================= -->
  <!-- You can set the default session timeout (in minutes) for all newly   -->
  <!-- created sessions by modifying the value below.                       -->


<session-config>
        <session-timeout>60</session-timeout>
</session-config>

date.setTime( date.getTime() + days * 86400000 );

You need to apply the logo class to the image...then float the ul

All these answers around here, as well as the answers in this question, suggest that loading absolute URLs, like "/foo/bar.properties" treated the same by class.getResourceAsStream(String) and class.getClassLoader().getResourceAsStream(String). This is NOT the case, at least not in my Tomcat configuration/version (currently 7.0.40).

MyClass.class.getResourceAsStream("/foo/bar.properties"); // works!  
MyClass.class.getClassLoader().getResourceAsStream("/foo/bar.properties"); // does NOT work!

Sorry, I have absolutely no satisfying explanation, but I guess that tomcat does dirty tricks and his black magic with the classloaders and cause the difference. I always used class.getResourceAsStream(String) in the past and haven't had any problems.

PS: I also posted this over here

This works just as well: http://jsfiddle.net/maniator/ge59E/3/

var reg = new RegExp(" ","g"); //<< just look for a space.

Initially it was to be a comma, however as the comma is often used as a decimal point it wouldnt be such good separator, hence others like the semicolon, mostly country dependant

I found one way to access the shared folder without giving the username and password.

We need to change the share folder protect settings in the machine where the folder has been shared.

Go to Control Panel > Network and sharing center > Change advanced sharing settings > Enable Turn Off password protect sharing option.

By doing the above settings we can access the shared folder without any username/password.

Here's a short snippet using subprocess. The check_call method either returns 0 for success, or raises an exception. This way, I don't have to parse the output of ping. I'm using shlex to split the command line arguments.

  import subprocess
  import shlex

  command_line = "ping -c 1 www.google.comsldjkflksj"
  args = shlex.split(command_line)
  try:
      subprocess.check_call(args,stdout=subprocess.PIPE,stderr=subprocess.PIPE)
      print "Website is there."
  except subprocess.CalledProcessError:
      print "Couldn't get a ping."

The first answer does't work anymore.

This worked for me:

from selenium.webdriver.firefox.options import Options as FirefoxOptions
from selenium import webdriver

options = FirefoxOptions()
options.add_argument("--headless")
driver = webdriver.Firefox(options=options)
driver.get("http://google.com")

$string = 'this is my world, not my world';
$find = 'world';
$replace = 'farm';
$result = preg_replace("/$find/",$replace,$string,1);
echo $result;

The better way is using 'background-size'.

.pnx-msg-icon .pnx-icon-msg-warning{
background-image: url("../pics/edit.png");
background-repeat: no-repeat;
background-size: 10px;
width: 10px;
height: 10px;
cursor: pointer;
}

even if your icon dimensions is bigger than 10px it will be 10px.

An additional consideraion that I have not seen in the answers already given, is that included columns can be of data types that are not allowed as index key columns, such as varchar(max).

This allows you to include such columns in a covering index. I recently had to do this to provide a nHibernate generated query, which had a lot of columns in the SELECT, with a useful index.

You have to understand how Unix interprets your input.

The standard Unix shell interpolates environment variables, and what are called globs before it passes the parameters to your program. This is a bit different from Windows which makes the program interpret the expansion.

Try this:

 $ echo *

This will echo all the files and directories in your current directory. Before the echo command acts, the shell interpolates the * and expands it, then passes that expanded parameter back to your command. You can see it in action by doing this:

$ set -xv
$ echo *
$ set +xv

The set -xv turns on xtrace and verbose. Verbose echoes the command as entered, and xtrace echos the command that will be executed (that is, after the shell expansion).

Now try this:

$ echo "*"

Note that putting something inside quotes hides the glob expression from the shell, and the shell cannot expand it. Try this:

$ foo="this is the value of foo"
$ echo $foo
$ echo "$foo"
$ echo '$foo'

Note that the shell can still expand environment variables inside double quotes, but not in single quotes.

Now let's look at your statement:

file="home/edward/bank1/fiche/Test*"

The double quotes prevent the shell from expanding the glob expression, so file is equal to the literal home/edward/bank1/finche/Test*. Therefore, you need to do this:

file=/home/edward/bank1/fiche/Test*

The lack of quotes (and the introductory slash which is important!) will now make file equal to all files that match that expression. (There might be more than one!). If there are no files, depending upon the shell, and its settings, the shell may simply set file to that literal string anyway.

You certainly have the right idea:

 file=/home/edward/bank1/fiche/Test*
 if  test -s $file
    then 
        echo "found one"
    else 
       echo "found none"
 fi

However, you still might get found none returned if there is more than one file. Instead, you might get an error in your test command because there are too many parameters.

One way to get around this might be:

if ls /home/edward/bank1/finche/Test* > /dev/null 2>&1
then
    echo "There is at least one match (maybe more)!"
else
    echo "No files found"
fi

In this case, I'm taking advantage of the exit code of the ls command. If ls finds one file it can access, it returns a zero exit code. If it can't find one matching file, it returns a non-zero exit code. The if command merely executes a command, and then if the command returns a zero, it assumes the if statement as true and executes the if clause. If the command returns a non-zero value, the if statement is assumed to be false, and the else clause (if one is available) is executed.

The test command works in a similar fashion. If the test is true, the test command returns a zero. Otherwise, the test command returns a non-zero value. This works great with the if command. In fact, there's an alias to the test command. Try this:

 $ ls -li /bin/test /bin/[

The i prints out the inode. The inode is the real ID of the file. Files with the same ID are the same file. You can see that /bin/test and /bin/[ are the same command. This makes the following two commands the same:

if test -s $file
then
    echo "The file exists"
fi

if [ -s $file ]
then
    echo "The file exists"
fi

Just for sake of completion, you can also do this:

array = []
array += [valueToBeInserted]

If it's a list of strings, this will also work:

array += 'string'

• In my case the issue is occurred because of am trying to open/show dialog box in onPostExecute AsyncTask

• However its an wrong method of showing dialog or Ui changes in onPostExecute.

• For that, we need to check the activity is in active Eg : !isFinishing() , if the activity is not finished then only able to show our dialog box or ui change.

  @Override
  protected void onPostExecute(String response_str) {
  
     getActivity().runOnUiThread(new Runnable() {
                  @Override
                  public void run() {
                      if (!((Activity) mContext).isFinishing()) {
                          try {
                              ShowAgilDialog();
                          } catch (WindowManager.BadTokenException e) {
                              Log.e("WindowManagerBad ", e.toString());
                          }
                      }
                  }
              });
  }
  

/dev/tty is a synonym for the controlling terminal (if any) of the current process. As jtl999 says, it's a character special file; that's what the c in the ls -l output means.

man 4 tty or man -s 4 tty should give you more information, or you can read the man page online here.

Incidentally, pwd > /dev/tty doesn't necessarily print to the shell's stdout (though it is the pwd command's standard output). If the shell's standard output has been redirected to something other than the terminal, /dev/tty still refers to the terminal.

You can also read from /dev/tty, which will normally read from the keyboard.

There are two problems in your code:

• the return value of scanf must be checked
• the %d conversion does not take overflows into account (blindly applying *10 + newdigit for each consecutive numeric character)

The first value you got (-104204697) is equals to 5623125698541159 modulo 2^32; it is thus the result of an overflow (if int where 64 bits wide, no overflow would happen). The next values are uninitialized (garbage from the stack) and thus unpredictable.

The code you need could be (similar to the answer of BLUEPIXY above, with the illustration how to check the return value of scanf, the number of items successfully matched):

#include <stdio.h>

int main(int argc, char *argv[]) {
    int i, j;
    short unsigned digitArray[16];
    i = 0;
    while (
        i != sizeof(digitArray) / sizeof(digitArray[0])
     && 1 == scanf("%1hu", digitArray + i)
    ) {
        i++;
    }
    for (j = 0; j != i; j++) {
        printf("%hu\n", digitArray[j]);
    }
    return 0;
}

<a href="#" class="btnTest">Test</a>


.btnTest{
   background:url('images/icon.png') no-repeat left center;
   padding-left:20px;
}    

my way:

in gradle.properties:

profile=profile-dev

in build.gradle add VM options -Dspring.profiles.active:

bootRun {
   jvmArgs = ["-Dspring.output.ansi.enabled=ALWAYS","-Dspring.profiles.active="+profile]
}

this will override application spring.profiles.active option

Another way to deal with this kind of problem is to use Exception().

for ii in range(200):
    try:
        for jj in range(200, 400):
            ...block0...
            if something:
                raise Exception()
    except Exception:
        continue
    ...block1...

For example:

for n in range(1,4):
    for m in range(1,4):
        print n,'-',m

result:

    1-1
    1-2
    1-3
    2-1
    2-2
    2-3
    3-1
    3-2
    3-3

Assuming we want to jump to the outer n loop from m loop if m =3:

for n in range(1,4):
    try:
        for m in range(1,4):
            if m == 3:
                raise Exception()            
            print n,'-',m
    except Exception:
        continue

result:

    1-1
    1-2
    2-1
    2-2
    3-1
    3-2

Adjusting the background-size is permitted. You still need to specify width and height of the block, however.

.pdflink:after {
    background-image: url('/images/pdf.png');
    background-size: 10px 20px;
    display: inline-block;
    width: 10px; 
    height: 20px;
    content:"";
}

#use return convertView;

Code:

public View getView(final int position, View convertView, ViewGroup parent) {

    //convertView = null;

    if (convertView == null) {

        LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        convertView = mInflater.inflate(R.layout.list_item, null);     

        TextView tv = (TextView) convertView.findViewById(R.id.name);
        Button rm_btn = (Button) convertView.findViewById(R.id.rm_btn);

        Model m = modelList.get(position);
        tv.setText(m.getName());

        // click listener for remove button  ??????????
        rm_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                modelList.remove(position);
                notifyDataSetChanged();
            }
        });
    }

Install the Bundler and Minifier into Visual Studio Extensions

Then you create a bundleconfig.json and enter the following like :

// Configure bundling and minification for the project.
// More info at https://go.microsoft.com/fwlink/?LinkId=808241
[
 {
    "outputFileName": "wwwroot/js/jquery.min.js",
    "inputFiles": [
      "node_modules/jquery/dist/jquery.js"
    ],
    // Optionally specify minification options
    "minify": {
      "enabled": true,
      "renameLocals": false
    },
    // Optionally generate .map file
    "sourceMap": false
  }
]

So the bundler and minifier (gulp based) has access to the source files (which should be excluded from Visual Studio and also excluded from GIT) and puts them into the wwwroot as specified

only side effect every time you save it will run this (but you can set it to run it manually)

In Info.plist add the entry "Fonts provided by application" and include the font names as strings:

Fonts provided by application
           Item 0        myfontname.ttf
           Item 1        myfontname-bold.ttf
           ...

Then check to make sure your font is included by running :

for (NSString *familyName in [UIFont familyNames]) {
    for (NSString *fontName in [UIFont fontNamesForFamilyName:familyName]) {
         NSLog(@"%@", fontName);
    }
}

Note that your ttf file name might not be the same name that you use when you set the font for your label (you can use the code above to get the "fontWithName" parameter):

[label setFont:[UIFont fontWithName:@"MyFontName-Regular" size:18]];

Named exports:

Let's say you create a file called utils.js, with utility functions that you want to make available for other modules (e.g. a React component). Then you would make each function a named export:

export function add(x, y) {
  return x + y
}

export function mutiply(x, y) {
  return x * y
}

Assuming that utils.js is located in the same directory as your React component, you can use its exports like this:

import { add, multiply } from './utils.js';
...
add(2, 3) // Can be called wherever in your component, and would return 5.

Or if you prefer, place the entire module's contents under a common namespace:

import * as utils from './utils.js'; 
...
utils.multiply(2,3)

Default exports:

If you on the other hand have a module that only does one thing (could be a React class, a normal function, a constant, or anything else) and want to make that thing available to others, you can use a default export. Let's say we have a file log.js, with only one function that logs out whatever argument it's called with:

export default function log(message) {
  console.log(message);
}

This can now be used like this:

import log from './log.js';
...
log('test') // Would print 'test' in the console.

You don't have to call it log when you import it, you could actually call it whatever you want:

import logToConsole from './log.js';
...
logToConsole('test') // Would also print 'test' in the console.

Combined:

A module can have both a default export (max 1), and named exports (imported either one by one, or using * with an alias). React actually has this, consider:

import React, { Component, PropTypes } from 'react';

Here is the changes you need to be done

just replace the carousel div with the below code

You have missed the '#' for data-target and add active class for the first item

<div id="carousel" class="carousel slide" data-ride="carousel">

UTF-8 is not a character set, it's an encoding. The character set for UTF-8 is Unicode. If you want to store Unicode text you use the nvarchar data type.

If the database would use UTF-8 to store text, you would still not get the text out as encoded UTF-8 data, you would get it out as decoded text.

You can easily store UTF-8 encoded text in the database, but then you don't store it as text, you store it as binary data (varbinary).

Let me just quote again the problem as described by @Steg

I had a similar problem to yours. I perform an ajax request that has 2 possible responses: one that redirects the browser to a new page and one that replaces an existing HTML form on the current page with a new one.

IMHO this is a real challenge and will have to be officially extended to the current HTTP standards.

I believe the new Http Standard will be to use a new status-code. meaning: currently 301/302 tells the browser to go and fetch the content of this request to a new location.

In the extended standard, it will say that if the response status: 308 (just an example), then the browser should redirect the main page to the location provided.

That being said; I'm inclined to already mimic this future behavior, and therefore when a document.redirect is needed, I have the server respond as:

status: 204 No Content
x-status: 308 Document Redirect
x-location: /login.html

When JS gets the "status: 204", it checks for the existence of the x-status: 308 header, and does a document.redirect to the page provided in the location header.

Does this make any sense to you?

If the user clicks Cancel, a zero-length string is returned. You can't differentiate this from entering an empty string. You can however make your own custom InputBox class...

EDIT to properly differentiate between empty string and cancel, according to this answer.

Your example

Private Sub test()
    Dim result As String
    result = InputBox("Enter Date MM/DD/YYY", "Date Confirmation", Now)
    If StrPtr(result) = 0 Then
        MsgBox ("User canceled!")
    ElseIf result = vbNullString Then
        MsgBox ("User didn't enter anything!")
    Else
        MsgBox ("User entered " & result)
    End If
End Sub

Would tell the user they canceled when they delete the default string, or they click cancel.

See http://msdn.microsoft.com/en-us/library/6z0ak68w(v=vs.90).aspx

An attempt to find the first would be:

$first = true; 
foreach ( $obj as $value )
{
  if ( $first )
  {
    // do something
    $first = false; //in order not to get into the if statement for the next loops
  }
  else
  {
    // do something else for all loops except the first
  }
}

Depending on your table type, locking will perform differently, but so will a SELECT count. For MyISAM tables a simple SELECT count(*) FROM table should not lock the table since it accesses meta data to pull the record count. Innodb will take longer since it has to grab the table in a snapshot to count the records, but it shouldn't cause locking.

You should at least have concurrent_insert set to 1 (default). Then, if there are no "gaps" in the data file for the table to fill, inserts will be appended to the file and SELECT and INSERTs can happen simultaneously with MyISAM tables. Note that deleting a record puts a "gap" in the data file which will attempt to be filled with future inserts and updates.

If you rarely delete records, then you can set concurrent_insert equal to 2, and inserts will always be added to the end of the data file. Then selects and inserts can happen simultaneously, but your data file will never get smaller, no matter how many records you delete (except all records).

The bottom line, if you have a lot of updates, inserts and selects on a table, you should make it InnoDB. You can freely mix table types in a system though.

Using balexandre's info:

SELECT usesysid, usename FROM pg_stat_activity;

The ~ selector is in fact the General sibling combinator (renamed to Subsequent-sibling combinator in selectors Level 4):

The general sibling combinator is made of the "tilde" (U+007E, ~) character that separates two sequences of simple selectors. The elements represented by the two sequences share the same parent in the document tree and the element represented by the first sequence precedes (not necessarily immediately) the element represented by the second one.

Consider the following example:

.a ~ .b {_x000D_
  background-color: powderblue;_x000D_
}

<ul>_x000D_
  <li class="b">1st</li>_x000D_
  <li class="a">2nd</li>_x000D_
  <li>3rd</li>_x000D_
  <li class="b">4th</li>_x000D_
  <li class="b">5th</li>_x000D_
</ul>

.a ~ .b matches the 4th and 5th list item because they:

• Are .b elements
• Are siblings of .a
• Appear after .a in HTML source order.

Likewise, .check:checked ~ .content matches all .content elements that are siblings of .check:checked and appear after it.

May be your dump.sql is having garbage character in beginning of your file or there is a blank line in beginning.

Use the json module to produce JSON output:

import json

with open(outputfilename, 'wb') as outfile:
    json.dump(row, outfile)

This writes the JSON result directly to the file (replacing any previous content if the file already existed).

If you need the JSON result string in Python itself, use json.dumps() (added s, for 'string'):

json_string = json.dumps(row)

The L is just Python syntax for a long integer value; the json library knows how to handle those values, no L will be written.

Demo string output:

>>> import json
>>> row = [1L,[0.1,0.2],[[1234L,1],[134L,2]]]
>>> json.dumps(row)
'[1, [0.1, 0.2], [[1234, 1], [134, 2]]]'

This usually happens to me when I have a using statement but have forgotten to reference the assembly that defines the namespace.

But in your case, as the namespace is defined in a file in your project, you have forgotten to tell the compiler about the snarlnetwork.cs file.

See csc compiler examples

This is the best you can do without JavaScript:

[draggable=true] {_x000D_
  cursor: move;_x000D_

  background-color: skyblue;_x000D_
}

<div draggable="true" class="resizable"></div>

Rails 4.0

you can use request.original_url, output will be as given below example

get "/articles?page=2"

request.original_url # => "http://www.example.com/articles?page=2"

Do what is suggested in the answer, but make sure you also click inside the VM so that OSX has the focus before you plug in the phone. In my case, I had to do that to make it work.

It only seems to because that is what it is printing out. But actually, you shouldn't write the logic this way. This is equivalent:

insert into errortable (dateupdated, table1id)
    values (sysdate, 1083);

It seems silly to convert the system date to a string just to convert it back to a date.

If you want to see the full date, then you can do:

select TO_CHAR(dateupdated, 'YYYY-MM-DD HH24:MI:SS'), table1id
from errortable;

I had the same issue, but none of other answers fully solved my problem. Answer by @Kiee was helpful, although all I could see in the GUI was a black screen (with underscore in top-left, this issue in Virtual Box also has been raised separately in stack overflow, again nothing helped).

Eventually, a solution proved to be very simple: check version of your virtual machine.

More precisely, I had a box from someone else with 64-bit Debian, but Virtual Box insisted to treat it as 32-bit, what I didn't notice. To change it, open Virtual Box, then open terminal and run

vagrant up

wait for the line

default: SSH auth method: private key

now you can hit ctrl+C (or wait for timeout) and run

vagrant halt

your virtual machine won't be destroyed, so you can see it in the menu of Virtual Box, but will be powered off, so you can change settings. Chose your machine in the menu, click 'Settings'->'General' and chose proper 'Version', for me it was 'Debian (64-bit)'. After this type vagrant up again.

If this is a case for you (or different changes in 'Settings' solved your issue), you can create new box from the repaired one typing

vagrant package --output mynew.box

Some more details: host 32-bit Ubuntu 12.04, guest 64-bit Debian 8.1, Virtual Box 5.0.14, Vagrant 1.8.1

Using <summary> and <details>

Using <summary> and <details> elements is the simplest but see browser support as current IE is not supporting it. You can polyfill though (most are jQuery-based). Do note that unsupported browser will simply show the expanded version of course, so that may be acceptable in some cases.

/* Optional styling */_x000D_
summary::-webkit-details-marker {_x000D_
  color: blue;_x000D_
}_x000D_
summary:focus {_x000D_
  outline-style: none;_x000D_
}

<details>_x000D_
  <summary>Summary, caption, or legend for the content</summary>_x000D_
  Content goes here._x000D_
</details>

See also how to style the <details> element (HTML5 Doctor) (little bit tricky).

Pure CSS3

The :target selector has a pretty good browser support, and it can be used to make a single collapsible element within the frame.

.details,_x000D_
.show,_x000D_
.hide:target {_x000D_
  display: none;_x000D_
}_x000D_
.hide:target + .show,_x000D_
.hide:target ~ .details {_x000D_
  display: block;_x000D_
}

<div>_x000D_
  <a id="hide1" href="#hide1" class="hide">+ Summary goes here</a>_x000D_
  <a id="show1" href="#show1" class="show">- Summary goes here</a>_x000D_
  <div class="details">_x000D_
    Content goes here._x000D_
  </div>_x000D_
</div>_x000D_
<div>_x000D_
  <a id="hide2" href="#hide2" class="hide">+ Summary goes here</a>_x000D_
  <a id="show2" href="#show2" class="show">- Summary goes here</a>_x000D_
  <div class="details">_x000D_
    Content goes here._x000D_
  </div>_x000D_
</div>

If you just need to search for one string within another, use the index function (or rindex if you want to start scanning from the end of the string):

if (index($string, $substring) != -1) {
   print "'$string' contains '$substring'\n";
}

To search a string for a pattern match, use the match operator m//:

if ($string =~ m/pattern/) {
    print "'$string' matches the pattern\n";       
}

The following adds one line after SearchPattern.

sed -i '/SearchPattern/aNew Text' SomeFile.txt

It inserts New Text one line below each line that contains SearchPattern.

To add two lines, you can use a \ and enter a newline while typing New Text.

POSIX sed requires a \ and a newline after the a sed function. [1] Specifying the text to append without the newline is a GNU sed extension (as documented in the sed info page), so its usage is not as portable.

select round(rand(checksum(newid()))*(10)+20,2)

Here the random number will come in between 20 and 30. round will give two decimal place maximum.

If you want negative numbers you can do it with

select round(rand(checksum(newid()))*(10)-60,2)

Then the min value will be -60 and max will be -50.

Connection in APPConfig

<connectionStrings>
  <add name="ConnectionString" connectionString="Data Source=192.168.1.25;Initial Catalog=Login;Persist Security Info=True;User ID=sa;Password=example.com"   providerName="System.Data.SqlClient" />
</connectionStrings>

In Class.Cs

public string ConnectionString
{
    get
    {
        return System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString"].ToString();
    }
}

It could be that there is a previous instance of the client still running and listening on port 5000.

In my particular case, I was trying to store a Base64 encoded file into a table BLOB field, using Mybatis.

So in my xml I had:

<insert id="save..." parameterType="...DTO">
    <selectKey keyProperty="id" resultType="long" order="BEFORE">
        SELECT SEQ.nextVal FROM DUAL
    </selectKey>
    insert into MYTABLE(
        ID,
        ...,
        PDF
    ) values (
        #{id, jdbcType=VARCHAR},
        ...,
        #{tcPdf, jdbcType=BLOB},
    )
</insert>

and in my DTO:

String getPdf(){
    return pdf;
}

That makes to Mybatis threat as if were a String char sequence and try to store it as a Varchar. So my solution was the following:

In my DTO:

Byte[] getPdf(){
    return pdf.getBytes();
}

And worked.

I hope this could help anybody.

It is possible to solve this problem using notepad++ by replacing Tabs with 4 Spaces:

1. Choose Search -> Find... or press Ctrl + F
2. Select the Replace tab
3. In the box named Search Mode choose Extended(\n, \r, \t, \0, \x...)
4. In the field Find what : write \t
5. In the field Replace with : press Space 4 times. Be sure that there is nothing else in this field.
6. Click on the button Replace All

<?php
$string = "producturl.php?id=736375493?=tm";
preg_match('~id=(\d+)~', $string, $m );
var_dump($m[1]); // $m[1] is your string
?>

Just call moment as a function without any arguments:

moment()

For timezone information with moment, look at the moment-timezone package: http://momentjs.com/timezone/

You can convert varchars to floats, and you can do it in the manner you have expressed. Your varchar must not be a numeric value. There must be something else in it. You can use IsNumeric to test it. See this:

declare @thing varchar(100)

select @thing = '122.332'

--This returns 1 since it is numeric.
select isnumeric(@thing)

--This converts just fine.
select convert(float,@thing)

select @thing = '122.332.'

--This returns 0 since it is not numeric.
select isnumeric(@thing)

--This convert throws.
select convert(float,@thing)

git config user.name only changes the name I commit. I still cannot push. This is how I solved it, and I think is an easy way to me.

1. Generate a SSH key under the user name you want to push on the computer you will use https://help.github.com/articles/connecting-to-github-with-ssh/

2. Add this key to the github user account that you want to push to https://help.github.com/articles/adding-a-new-ssh-key-to-your-github-account/

3. Choose to Clone with SSH

You can push in as this user to that repo now.

You can reverse the rows in an even simpler way:

df[::-1]

I have also met this issue and wasted a lot of time debugging it.

First, make sure that the path you provide is valid, i.e., there is an image in that path.

Next, you should be aware that Opencv doesn't support image paths which contain unicode characters (see ref). If your image path contains Unicode characters, you can use the following code to read the image:

import numpy as np
import cv2

# img is in BGR format if the underlying image is a color image
img = cv2.imdecode(np.fromfile(im_path, dtype=np.uint8), cv2.IMREAD_UNCHANGED)

$gender = $_POST['gender'];
echo $gender;  

it will echoes the selected value.

If you are just comparing numbers, I think there's no need to change syntax, just correct those lines, lines 6 and 9 brackets.

Line 6 before: if [ "$age" -le "7"] -o [ "$age" -ge " 65" ]

After: if [ "$age" -le "7" -o "$age" -ge "65" ]

Line 9 before: elif [ "$age" -gt "7"] -a [ "$age" -lt "65"]

After: elif [ "$age" -gt "7" -a "$age" -lt "65" ]

My issue was: I had to do forward declaration of the class whose ctor was "unresolved external".

In the file where I got the error, I had to put something like this:

#include "ClassB" 

class ClassB; // this solved the problem

class ClassA{
    void foo(){
        ClassB* tmp = new ClassB();
        // ...
    }
};

Of course, my project is much more complicated and this is just a snippet example. Also when using namespaces, declare them as well.

I voted for Josh's answer, but would like to add one more to the list:

System.InvalidOperationException should be thrown if the argument is valid, but the object is in a state where the argument shouldn't be used.

Update Taken from MSDN:

InvalidOperationException is used in cases when the failure to invoke a method is caused by reasons other than invalid arguments.

Let's say that your object has a PerformAction(enmSomeAction action) method, valid enmSomeActions are Open and Close. If you call PerformAction(enmSomeAction.Open) twice in a row then the second call should throw the InvalidOperationException (since the arugment was valid, but not for the current state of the control)

Since you're already doing the right thing by programming defensively I have one other exception to mention is ObjectDisposedException. If your object implements IDisposable then you should always have a class variable tracking the disposed state; if your object has been disposed and a method gets called on it you should raise the ObjectDisposedException:

public void SomeMethod()
{
    If (m_Disposed) {
          throw new ObjectDisposedException("Object has been disposed")
     }
    // ... Normal execution code
}

Update: To answer your follow-up: It is a bit of an ambiguous situation, and is made a little more complicated by a generic (not in the .NET Generics sense) data type being used to represent a specific set of data; an enum or other strongly typed object would be a more ideal fit--but we don't always have that control.

I would personally lean towards the ArgumentOutOfRangeException and provide a message that indicates the valid values are 1-12. My reasoning is that when you talk about months, assuming all integer representations of months are valid, then you are expecting a value in the range of 1-12. If only certain months (like months that had 31 days) were valid then you would not be dealing with a Range per-se and I would throw a generic ArgumentException that indicated the valid values, and I would also document them in the method's comments.

I guess the quickest way is just to disable the domain check while you're developing it

They should have the same time, the update is supposed to be atomic, meaning that whatever how long it takes to perform, the action is supposed to occurs as if all was done at the same time.

If you're experiencing a different behaviour, it's time to change for another DBMS.

It's because you have included a leading / in your file path. The / makes it start at the top of your filesystem. Note: filesystem path, not Web site path (you're not accessing it over HTTP). You can use a relative path with include_once (one that doesn't start with a leading /).

You can change it to this:

include_once 'headerSite.php';

That will look first in the same directory as the file that's including it (i.e. C:\xampp\htdocs\PoliticalForum\ in your example.

An interface defines a simple contract of methods all implementing classes must implement. When a class implements an interface, it must provide implementations for all its methods.

I guess the poster assumes a certain level of knowledge about the language.

Try using replaceWith() or replaceAll()

http://api.jquery.com/replaceAll/

As an addendum, if you want to reapply your changes on top of the remote, you can also try:

git pull --rebase origin master

If you then want to undo some of your changes (but perhaps not all of them) you can use:

git reset SHA_HASH

Then do some adjustment and recommit.

USE

Validators.min(5)

It can be used while creating a formGroup variable along with other validators, as in

dueAmount: ['', [Validators.required, Validators.pattern(/^[+]?([0-9]+(?:[\.][0-9]*)?|\.[0-9]+)$/), Validators.min(5)]]

Not sure if it is in Angular 2, but is available in Angular 5

I've had this problem. See The Python "Connection Reset By Peer" Problem.

You have (most likely) run afoul of small timing issues based on the Python Global Interpreter Lock.

You can (sometimes) correct this with a time.sleep(0.01) placed strategically.

"Where?" you ask. Beats me. The idea is to provide some better thread concurrency in and around the client requests. Try putting it just before you make the request so that the GIL is reset and the Python interpreter can clear out any pending threads.

Yes, It is required to add libraries after the source files/objects files. This command will solve the problem:

gcc -static -L/usr/lib -I/usr/lib main.c -ltommath

In your case it was some other process that was using the port and as indicated in the comments, sudo netstat -pna | grep 3000 helped you in solving the problem.

While in other cases (I myself encountered it many times) it mostly is the same container running at some other instance. In that case docker ps was very helpful as often I left the same containers running in other directories and then tried running again at other places, where same container names were used.

How docker ps helped me: docker rm -f $(docker ps -aq) is a short command which I use to remove all containers.

Edit: Added how docker ps helped me.

I used this code:

public class MainActivity extends Activity
    {
    .
    .
    .
    @Override
    protected void onCreate(Bundle savedInstanceState)
        {
        super.onCreate(savedInstanceState);
        .
        .
        .
        }

    @Override
    protected void onResume()
        {
        super.onResume();
        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION);
        registerReceiver(broadcastReceiver, intentFilter);  
        }

    @Override
    protected void onPause()
        {
        super.onPause();
        unregisterReceiver(broadcastReceiver);
        }

    private final BroadcastReceiver broadcastReceiver = new BroadcastReceiver()
        {
        @Override
        public void onReceive(Context context, Intent intent)
            {
            final String action = intent.getAction();
            if (action.equals(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION))
                {
                if (intent.getBooleanExtra(WifiManager.EXTRA_SUPPLICANT_CONNECTED, false))
                    {
                    // wifi is enabled
                    }
                else
                    {
                    // wifi is disabled
                    }
                }
            }
        };
    }

In other words on keeping this brief: in case of root, location argument specified is part of filesystem's path and URI . On the other hand — for alias directive argument of location statement is part of URI only

So, alias is a different name that maps certain URI to certain path in the filesystem, whereas root appends location argument to the root path given as argument to root directive.

Googling gives me this:

Command A & Command B

Execute Command A, then execute Command B (no evaluation of anything)

Command A | Command B

Execute Command A, and redirect all its output into the input of Command B

Command A && Command B

Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B

Command A || Command B

Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B

Try this:

if ( jQuery('#postageyes').is(':checked') ){ ... }

I've just had this problem with MariaDB/InnoDB and was able to fix it by

• create the required table in the correct database in another MySQL/MariaDB instance
• stop both servers
• copy .ibd, .frm files to original server
• start both servers
• drop problem table on both servers

In the jquery ready function you can do something like below -

var hrefcode = $('a[id*=linkbutton]').attr('href').split(':');
var onclickcode = "javascript: if`(Condition()) {" + hrefcode[1] + ";}";
$('a[id*=linkbutton]').attr('href', onclickcode);

I tried the above suggested npm install --global --production windows-build-tools but found that the installation was always hanging forever.

I managed to fix the problem by installing Node.js 8 instead of Node.js 10.

Just try socket.disconnect(true) on the server side by emitting any event from the client side.

fish starts by executing commands in ~/.config/fish/config.fish. You can create it if it does not exist:

vim ~/.config/fish/config.fish

and save it with :wq

step1. make configuration file (like .bashrc)

config.fish

step2. just write your alias like this;

alias rm="rm -i"

here's your amended script

#!/bin/bash    
folder="ABC" #no spaces between assignment    
useracct='test'    
day=$(date "+%d") # use $() to assign return value of date command to variable    
month=$(date "+%B")     
year=$(date "+%Y")    
folderToBeMoved="/users/$useracct/Documents/Archive/Primetime.eyetv"    
newfoldername="/Volumes/Media/Network/$folder/$month$day$year"    
ECHO "Network is $network" $network    
ECHO "day is $day"    
ECHO "Month is $month"    
ECHO "YEAR is $year"    
ECHO "source is $folderToBeMoved"    
ECHO "dest is $newfoldername"    

mkdir "$newfoldername"

You need to do two things:

1. Add async before function.

2. Start your function with return.

   var gulp = require('gulp');
   
   gulp.task('message', async function() {
       return console.log("HTTP Server Started");
   });
   

A boolean cannot be null in java.

A Boolean, however, can be null.

If a boolean is not assigned a value (say a member of a class) then it will be false by default.

Also you have to give permission if you are using >1.6 SDK

uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"

in AndroidManifest.xml file

Other have hit this one on the head:

• the standard arguments to main(int argc, char **argv) give you direct access to the command line (after it has been mangled and tokenized by the shell)
• there are very standard facility to parse the command line: getopt() and getopt_long()

but as you've seen the code to use them is a bit wordy, and quite idomatic. I generally push it out of view with something like:

typedef
struct options_struct {
   int some_flag;
   int other_flage;
   char *use_file;
} opt_t;
/* Parses the command line and fills the options structure, 
 * returns non-zero on error */
int parse_options(opt_t *opts, int argc, char **argv);

Then first thing in main:

int main(int argc, char **argv){
   opt_t opts;
   if (parse_options(&opts,argc,argv)){
      ...
   } 
   ...
}

Or you could use one of the solutions suggested in Argument-parsing helpers for C/UNIX.

Try this:

private string GetJArrayValue(JObject yourJArray, string key)
{
    foreach (KeyValuePair<string, JToken> keyValuePair in yourJArray)
    {
        if (key == keyValuePair.Key)
        {
            return keyValuePair.Value.ToString();
        }
    }
}

You can try

echo "<SCRIPT>alert(\"Login Successful Redirecting To Previous Page \");history.go(-2)</SCRIPT>";

Or

echo "<SCRIPT>alert(\"Login Successful Redirecting To Previous Page \");history.go(-1)</SCRIPT>";

GoodNews from v.9.6 and above, View editing are now native from psql. Just invoke \ev command. View definitions will show in your configured editor.

julian@assange=# \ev {your_view_names}

Bonus. Some useful command to interact with query buffer.

Query Buffer
  \e [FILE] [LINE]       edit the query buffer (or file) with external editor
  \ef [FUNCNAME [LINE]]  edit function definition with external editor
  \ev [VIEWNAME [LINE]]  edit view definition with external editor
  \p                     show the contents of the query buffer
  \r                     reset (clear) the query buffer
  \s [FILE]              display history or save it to file
  \w FILE                write query buffer to file

The best way to do it now is:

android.util.Patterns.WEB_URL.matcher(linkUrl).matches();

If you want to know the day of the week for your code to do something with it, DateTime.Now.DayOfWeek will do the job.

If you want to display the day of week to the user, DateTime.Now.ToString("dddd") will give you the localized day name, according to the current culture (MSDN info on the "dddd" format string).

You can find the answer in this video https://www.youtube.com/watch?v=SYoN-OvdZ3M&list=PLonJJ3BVjZW6CtAMbJz1XD8ELUs1KXaTD&index=19 and the next 3 videos. All the touch events are explained very well, it's very clear and full of examples.

I did the following change and it worked for me.Hope it helps someone.

Try this

$("#mydiv div.myclass")

var timeoutId = 0;

$('#myElement').on('mousedown', function() {
    timeoutId = setTimeout(myFunction, 1000);
}).on('mouseup mouseleave', function() {
    clearTimeout(timeoutId);
});

Edit: correction per AndyE...thanks!

Edit 2: using bind now for two events with same handler per gnarf

I face similar issue while importing TensorFlow. If you are using Tensorflow which uses Pandas library, I suggest restarting your kernel of Anaconda. This works for me.

Try

sudo -su db2inst1 /opt/ibm/db2/V9.7/bin/db2 force application \(1995\)

Here's another approach, in case you want split a string with a delimiter.

import pyspark.sql.functions as f

df = spark.createDataFrame([("1:a:2001",),("2:b:2002",),("3:c:2003",)],["value"])
df.show()
+--------+
|   value|
+--------+
|1:a:2001|
|2:b:2002|
|3:c:2003|
+--------+

df_split = df.select(f.split(df.value,":")).rdd.flatMap(
              lambda x: x).toDF(schema=["col1","col2","col3"])

df_split.show()
+----+----+----+
|col1|col2|col3|
+----+----+----+
|   1|   a|2001|
|   2|   b|2002|
|   3|   c|2003|
+----+----+----+

I don't think this transition back and forth to RDDs is going to slow you down... Also don't worry about last schema specification: it's optional, you can avoid it generalizing the solution to data with unknown column size.

The difference is that, for example, a

List<HashMap<String,String>>

is a

List<? extends Map<String,String>>

but not a

List<Map<String,String>>

So:

void withWilds( List<? extends Map<String,String>> foo ){}
void noWilds( List<Map<String,String>> foo ){}

void main( String[] args ){
    List<HashMap<String,String>> myMap;

    withWilds( myMap ); // Works
    noWilds( myMap ); // Compiler error
}

You would think a List of HashMaps should be a List of Maps, but there's a good reason why it isn't:

Suppose you could do:

List<HashMap<String,String>> hashMaps = new ArrayList<HashMap<String,String>>();

List<Map<String,String>> maps = hashMaps; // Won't compile,
                                          // but imagine that it could

Map<String,String> aMap = Collections.singletonMap("foo","bar"); // Not a HashMap

maps.add( aMap ); // Perfectly legal (adding a Map to a List of Maps)

// But maps and hashMaps are the same object, so this should be the same as

hashMaps.add( aMap ); // Should be illegal (aMap is not a HashMap)

So this is why a List of HashMaps shouldn't be a List of Maps.

It is possible, with the usual CSS caveats and if the HTML code can be modified. If you add the required attribute to the element, then the element will match :invalid or :valid according to whether the value of the control is empty or not. If the element has no value attribute (or it has value=""), the value of the control is initially empty and becomes nonempty when any character (even a space) is entered.

Example:

<style>
#foo { background: yellow; }
#foo:valid { outline: solid blue 2px; }
#foo:invalid { outline: solid red 2px; }
</style>
<input id=foo required>

The pseudo-classed :valid and :invalid are defined in Working Draft level CSS documents only, but support is rather widespread in browsers, except that in IE, it came with IE 10.

If you would like to make “empty” include values that consist of spaces only, you can add the attribute pattern=.*\S.*.

There is (currently) no CSS selector for detecting directly whether an input control has a nonempty value, so we need to do it indirectly, as described above.

Generally, CSS selectors refer to markup or, in some cases, to element properties as set with scripting (client-side JavaScript), rather than user actions. For example, :empty matches element with empty content in markup; all input elements are unavoidably empty in this sense. The selector [value=""] tests whether the element has the value attribute in markup and has the empty string as its value. And :checked and :indeterminate are similar things. They are not affected by actual user input.

You need to use jQuery('#bar')[0].click(); to simulate a mouse click on the actual DOM element (not the jQuery object), instead of using the .trigger() jQuery method.

Note: DOM Level 2 .click() doesn't work on some elements in Safari. You will need to use a workaround.

You can easily write a bit code that will read in a file. You can either assume one sql statement per line, or assume the ;

So, assuming you have a text file such as:

insert into tblTest (t1) values ('2000');

update tbltest set t1 = '2222'
       where id = 5;


insert into tblTest (t1,t2,t3) 
       values ('2001','2002','2003');

Note the in the above text file we free to have sql statements on more then one line.

the code you can use to read + run the above script is:

Sub SqlScripts()

   Dim vSql       As Variant
   Dim vSqls      As Variant
   Dim strSql     As String
   Dim intF       As Integer

   intF = FreeFile()
   Open "c:\sql.txt" For Input As #intF
   strSql = input(LOF(intF), #intF)
   Close intF
   vSql = Split(strSql, ";")

   On Error Resume Next
   For Each vSqls In vSql
      CurrentDb.Execute vSqls
   Next

End Sub

You could expand on placing some error msg if the one statement don't work, such as

if err.number <> 0 then
   debug.print "sql err" & err.Descripiton & "-->" vSqls
end dif

Regardless, the above split() and string read does alow your sql to be on more then one line...

for create method:

-(void)mymethods:(NSString *)aCont withsecond:(NSString *)a-second {
//method definition...
}

for call the method:

[mymethods:self.contoCorrente withsecond:self.asecond];

HTML5 comes with File API spec, which allows you to create applications that let the user interact with files locally; That means you can load files and render them in the browser without actually having to upload the files. Part of the File API is the FileReader interface which lets web applications asynchronously read the contents of files .

Here's a quick example that makes use of the FileReader class to read an image as DataURL and renders a thumbnail by setting the src attribute of an image tag to a data URL:

The html code:

<input type="file" id="files" />
<img id="image" />

The JavaScript code:

document.getElementById("files").onchange = function () {
    var reader = new FileReader();

    reader.onload = function (e) {
        // get loaded data and render thumbnail.
        document.getElementById("image").src = e.target.result;
    };

    // read the image file as a data URL.
    reader.readAsDataURL(this.files[0]);
};

Here's a good article on using the File APIs in JavaScript.

The code snippet in the HTML example below filters out images from the user's selection and renders selected files into multiple thumbnail previews:

function handleFileSelect(evt) {_x000D_
    var files = evt.target.files;_x000D_
_x000D_
    // Loop through the FileList and render image files as thumbnails._x000D_
    for (var i = 0, f; f = files[i]; i++) {_x000D_
_x000D_
      // Only process image files._x000D_
      if (!f.type.match('image.*')) {_x000D_
        continue;_x000D_
      }_x000D_
_x000D_
      var reader = new FileReader();_x000D_
_x000D_
      // Closure to capture the file information._x000D_
      reader.onload = (function(theFile) {_x000D_
        return function(e) {_x000D_
          // Render thumbnail._x000D_
          var span = document.createElement('span');_x000D_
          span.innerHTML = _x000D_
          [_x000D_
            '<img style="height: 75px; border: 1px solid #000; margin: 5px" src="', _x000D_
            e.target.result,_x000D_
            '" title="', escape(theFile.name), _x000D_
            '"/>'_x000D_
          ].join('');_x000D_
          _x000D_
          document.getElementById('list').insertBefore(span, null);_x000D_
        };_x000D_
      })(f);_x000D_
_x000D_
      // Read in the image file as a data URL._x000D_
      reader.readAsDataURL(f);_x000D_
    }_x000D_
  }_x000D_
_x000D_
  document.getElementById('files').addEventListener('change', handleFileSelect, false);

<input type="file" id="files" multiple />_x000D_
<output id="list"></output>

If you need this for several words or elements, but can't apply it to a whole TD or similar, the Span tag can be used.

<span style="white-space: nowrap">Text to break together</span>
    or 
<span class=nobr>Text to break together</span>

If you use the class version, remember to set up the CSS as detailed in the accepted answer.

This took me forever to find something that works on my mac. Here's what worked for me:

brew install xmlformat
cat unformatted.html | xmlformat

Wouldn't occam's razor say to just do this until you need something more complex? It's a bit of a hack, but may suit the needs of someone that wants a quick fix.

.navbar-default .container-fluid{
    background-color:#62ADD7; // Change the color
    margin: -1px -1px 10px -1px; // Get rid of the border
}

We can easily create and export/download the excel file with any separator (in this answer I am using the comma separator) using javascript. I am not using any external package for creating the excel file.

    var Head = [[_x000D_
        'Heading 1',_x000D_
        'Heading 2', _x000D_
        'Heading 3', _x000D_
        'Heading 4'_x000D_
    ]];_x000D_
_x000D_
    var row = [_x000D_
       {key1:1,key2:2, key3:3, key4:4},_x000D_
       {key1:2,key2:5, key3:6, key4:7},_x000D_
       {key1:3,key2:2, key3:3, key4:4},_x000D_
       {key1:4,key2:2, key3:3, key4:4},_x000D_
       {key1:5,key2:2, key3:3, key4:4}_x000D_
    ];_x000D_
_x000D_
for (var item = 0; item < row.length; ++item) {_x000D_
       Head.push([_x000D_
          row[item].key1,_x000D_
          row[item].key2,_x000D_
          row[item].key3,_x000D_
          row[item].key4_x000D_
       ]);_x000D_
}_x000D_
_x000D_
var csvRows = [];_x000D_

This worked for me:

exclude: [/bower_components/, /node_modules/]

module.loaders

A array of automatically applied loaders.

Each item can have these properties:

test: A condition that must be met

exclude: A condition that must not be met

include: A condition that must be met

loader: A string of "!" separated loaders

loaders: A array of loaders as string

A condition can be a RegExp, an absolute path start, or an array of one of these combined with "and".

See http://webpack.github.io/docs/configuration.html#module-loaders

Thanks for the pointers.

I don't know, whether this is the best approach to the problem or not, but here is how I got it to work. I referenced the Microsoft XML, v2.6 dll in my VBA, and then the following code snippet, gives me the required values

Dim objXML As MSXML2.DOMDocument

Set objXML = New MSXML2.DOMDocument

If Not objXML.loadXML(strXML) Then  'strXML is the string with XML'
    Err.Raise objXML.parseError.ErrorCode, , objXML.parseError.reason
End If
 
Dim point As IXMLDOMNode
Set point = objXML.firstChild

Debug.Print point.selectSingleNode("X").Text
Debug.Print point.selectSingleNode("Y").Text

Call onBackPressed after overriding it in your activity.

Just use Analyze | Inspect Code with appropriate inspection enabled (Unused declaration under Declaration redundancy group).

Using IntelliJ 11 CE you can now "Analyze | Run Inspection by Name ... | Unused declaration"

Dupx

Dupx is a simple *nix utility to redirect standard output/input/error of an already running process.

Motivation

I've often found myself in a situation where a process I started on a remote system via SSH takes much longer than I had anticipated. I need to break the SSH connection, but if I do so, the process will die if it tries to write something on stdout/error of a broken pipe. I wish I could suspend the process with ^Z and then do a

bg %1 >/tmp/stdout 2>/tmp/stderr 

Unfortunately this will not work (in shells I know).

Little Edit

Try adding

return new JavascriptResult() { Script = "alert('Successfully registered');" };

in place of

return RedirectToAction("Index");
